Developmentally Appropriated Practice For Preschoolers Education Essay

Nowadays more and more parents are looking for appropriate attention for their kids. DAP gives an chance realize all wants and outlook of parents. Developmentally Appropriate Practice ( DAP ) is a attention that takes into history each kid ‘s degree of physical, social-emotional, linguistic communication, rational, and adaptative development. Children provided with the chance to prosecute in DAP are better set up for success in school and society. The subject of DAP is discussed in the book â€Å" Developmentally Appropriate Practice: Course of study and Development in Early Education † , by Carol Gestwicki. The book explains what DAP is and touches such subjects as developmentally appropriate physical, societal, emotional, cognitive and linguistic communication environments. The methodic and plan of DAP differ for every age group ( Infants, Toddlers, Preschoolers, Primary-Aged Children ) . The preschool age kids develop larning activities that include linguistic communication, motor physical activity and motions. Such activities normally include mystifiers and blocks, wheel playthings and climbers, dramatic drama moving and narrative relation. Preschoolers enjoy different experiences and activities such as cutting paper and fabric some cookery and other art activities. Children of this age already can acknowledge forms, colourss ; they can even utilize simple math and problem-solving accomplishments. At this age kids combine thoughts, their memory is turning and their motor accomplishments are bettering. Children show a large involvement in the written linguistic communication. Kids besides develop an involvement in the universe around them, are fond of particular events and trips. Adults should listen to kids, promote originative drama, fall in them in activities, aid to construct self-esteem, and set consistent bounds. Preschoolers need grownups to promote and back up their originative drama, articulation in their activities, assist them to understand societal norms, and set consistent bounds with them. Three and four-year-old kids should be given ample chances to derive experience with linguistic communication, big motor physical activities, motion, and all right motor activities. Adults who work with kindergartners should hold warm, fostering personality with appropriate behaviour, willing to larn, be dependable, to understand the emerging demand for the kindergartner to set up friendly relationships and have. Adult should accept different attention giving methods and techniques, besides read, talk and listen to the kid. Developmentally appropriate patterns include social/emotional, cognitive, physical and linguistic communication development. Social and emotional development of kindergartners. It is really of import for kindergartners to develop their accomplishments in societal and emotional domains which are keys to their success in life, every bit good as, school. The surveies of scientists explain how necessary societal and emotional preparedness is to a kindergarten activities, success in school, and their ulterior grownup achievements. There are three cardinal ends for societal and emotional development. The first is the Sense of Self. It deals with a fact of how childs feel valued and accepted by the people whom they love. The 2nd is the Responsibility for Self and Others. It deals with developing wonts and character qualities such as duty, and independency, autonomy of a kid, and following regulations and modus operandis. The 3rd key is the Prosocial Behavior, which works with qualities such as empathy and sharing that that will assist kids to collaborate in the universe. Cognitive development of kindergartners is the procedure of larning how to believe and happen a ground. Such accomplishments are connected with literacy and mathematics. Such domains as scientific discipline and societal surveies, are besides includes the same as the humanistic disciplines, and engineering. Such development is non merely memorising facts. Preschool kids are â€Å" larning to larn. † Such accomplishment is of import for future acquisition. The three ends are: acquisition and job resolution, logical thought, representation and symbolic thought activity. Learning and Problem Solving teaches small kids how they should information, resources, and stuffs they have. Kids learn how to believe about their thoughts, how to do anticipations, and besides how to prove possible solutions. The qualities such as wonder, continuity, and using cognition, make larning more of import than merely larning new facts about the universe. Logical Thinking helps kindergartners to understand the information they are garnering. Children attempt to compare and contrast things, to screen and sort. Besides kids learn to number, step and so on. Representation and Symbolic Thinking aid kids to concentrate on how they use symbols in idea. Symbols can be objects, people or representations through drawings. Symbolic believing besides includes. Physical accomplishments are besides really of import for the bettering accomplishments in reading, composing, scientific discipline, and math. Physical development affects societal and emotional development because childs gain assurance while they learn what their organic structures can make. The more childs can make, the more their want to seek new and more hard undertakings appear. The two ends for motor accomplishments are: gross motor and all right motor. Gross motor development involves the motions that are controlled by the organic structure ‘s big musculuss while all right motor development wage attending to commanding, coordination, and sleight of the little musculuss in the kids ‘s custodies. Environment for activities should be clean and safe ; the plaything and stuffs should be displayed on unfastened, low shelves. There should be countries for the undermentioned types of acquisition centres or infinite for kids to play with the following types of stuffs: dramatic drama, blocks, art: colouring, picture, pulling, pasting, etc. The country should include sand and H2O district for playing games. Working stuffs should include books. Activities should include music and motions, while the manipulatives would be mystifiers, nogs, little building points scientific discipline. There besides need to be included some sort of big motor country for throwing, siting, mounting, jumping, running ; are for separate cot/mat for single sleeping ; some private, getaway infinites. All countries ought to be soft. The stuffs that are normally used in DAP with kindergartners are siting playthings, balls/bean bags to throw, mounting equipment, books, blocks ( different forms, textures, weights, colourss, sizes plus vehicles, animate beings ) . Such dramatic drama stuffs as vesture, theme points ( house, physician ‘s office, food market shop, etc. ) are besides used. Teachers and parents should utilize art supplies: assorted sorts of pigments, crayons, markers, chalk, assorted sorts of paper, drama dough, gum, paste, scissors, etc. while the composing supplies should include: pens, pencils, paper, stapling machine, paper cartridge holders, envelopes, following letters and Numberss, etc. Language development plays a great function in development of kindergartners because a foundation in linguistic communication development gives childs accomplishments needed to go successful scholars. The researches show that kids who have large linguistic communication experiences in preschool are more volitionally to do stronger their linguistic communication and literacy accomplishments. The ability of kids to listen, compose, read and talk is developed interdependently. The ends for linguistic communication development are: hearing, speech production, reading and composing. Listening and Talking involves spoken linguistic communication. Such accomplishments as holding a big vocabulary and ability to show oneself are of import for kids. Reading and Writing involves the aid of grownups to do sense of written linguistic communication for kids as they enjoy reading. Such development additions kid ‘s ability to manage books and understand the intent of book and how it works, it besides teaches how to recite a narrative. Preschoolers learn the alphabet and words while playing games. Developmentally appropriate pattern for kids should be alone for every kid, because all kids are different and have different abilities. Parents should cognize that the acquisition and development of their kids depends on heed to all facets of a kid ‘s wellbeing. Attention should be paid to physical, societal, emotional and cognitive dimensions of kid development.

The Great Charlemagne

There was relatively little commerce in Western Europe. Roads, bridges, and the infrastructure generally were non-existent. Furthermore, the countryside was unsafe for travel due to a lack of organized law enforcement. Small villages had to take care of themselves; therefore, manufacturing was carried on only to the extent that was needed to supply local needs. In the little kingdoms or principalities, the lands over which a King ruled were regarded as no different from other property. Among the Franks, all sons were entitled to a share. Therefore, when a King died, each son became a King over his own little kingdom. Thus, many political units became small so there were no uniform laws or policies. This lack of unity made them vulnerable to enemies as well as conflict from within. Bullough points out that the loyalty of a warrior or subject to his chosen leader was not a light matter. The author does not contrast that concept of loyalty however, with our present ideas of loyalty to the homeland or institution. â€Å"The apprenticeship of a King† describes how Charlemagne gained power through conquest and diplomacy. In 768, King Pippin died and his kingdom was divided between his two sons. Charles, the elder, and the younger was Carloman. The author says that little is known of Charles† boyhood. When he was of the right age, it is recorded that he worked eagerly at riding and hunting. It was the custom of the Franks to ride and be practiced in the use of arms and ways of hunting. We may reasonably infer that acquiring these skills formed a major part of his early education. Charles was not a â€Å"man of letters† and the author makes no attempt at explaining this other than to point out that literacy was considered unimportant at that time for anyone other than the clergy and Charles didn†t become interested in â€Å"letters† until later in life. Bullough explains a number of experiences in public duties and responsibilities, which were assigned to Charles by his father, thus, giving him an apprenticeship to rule the kingdom. For some reason tension between Charles and his brother began shortly after their accession. The author explains a number of conflicts. The younger brother died however, at the end of 771 and a number of prominent people in his kingdom offered allegiance to Charles. Bullough names and explains those subjects. The result was the re-uniting of those territories, which helped to establish the kingdom of the Franks. The author describes in detail the military conquests of Charlemagne. The text includes maps of the territories and battlefields. It is stated that to some areas, Charles may have come as a liberator from the infidel yoke, but to many other peoples who bordered his dominions, Christian and Non-Christian alike, he was an oppressive enemy, like so many others before and after. In 880, Pope Leo III called on Charles for assistance when he faced charges of simony, perjury, and adultery. Charles acted with careful deliberation when dealing with this matter. Charles was asked to preside over the Pope†s hearing. He did so, and Leo was cleared of all charges. Two days later, Leo placed a crown on Charles head and proclaimed him Holy Roman Emperor. This gave Charles the â€Å"Devine Right to Rule† according to the Roman Church. The author does not infer from any of this information. Personally, it seems that Charlemagne united an empire by conquest and ruled by the authority of the Pope. Bullough does not suggest that during this time the government and the church became so intervened that there were really one and the same. Having conquered an empire and established the â€Å"Devine Right to Rule†, Charles then, according to Bullough, began to establish some uniformity within the empire. The ancient concept of public order had not been entirely destroyed by the invasion of barbarians within the empire. But, as law and order became weaker, its place was partly taken by the Churchmen†s Nations of peace and right order. The author explains how Charles established a system of courts to see that justice was done to all free disputants and to protect widows and orphans. The author does not state any conclusions as to the results of the establishment of a uniform legal system. Although Charles was not literate, he seems to have placed value in education. Bullough credits him with a revival of learning or a â€Å"Carolingian Renaissance†. Charlemagne saw that education was in serious decline. So he gathered together at his court some of the finest minds of his day. He also sponsored monasteries where ancient books were preserved and copied. He reformed the palace school and saw that monastic schools were set up throughout the realm. The idea of learning was given a time and a place to flourish. The â€Å"Carolingian Renaissance† was an isolated phenomenon. Learning did not catch fire throughout Europe. Only in the royal court and monasteries was there any real focus on education. Yet because of Charles† interest in preserving and reviving knowledge, a wealth of ancient manuscripts was copied for future generations. Just as important, a tradition of learning was established in European monastic communities. These monasteries helped to overcome the threat of the extinction of Latin culture. The Carolingian handwriting that evolved during Charlemagne†s reign was developed to increase the legibility of the numerous manuscripts the monks turned out at this time. These small letters, known as â€Å"Carolingian Miniscule† became the basis of the lower case letters we use today. Ninety percent of the works of ancient Rome now in existence are preserved in the form of manuscripts copied in a Carolingian Monastery. Bullough devotes much time to the areas on art and architecture during the Carolingian period. Included are photographs of buildings, which are standing, and in use today. There are also ground plan drawings of buildings and samples of other works of art. Being closely aligned with the church, it is not surprising that the major examples of Carolingian architecture are churches and Biblical illustrations make up much of the art. These are not the only works. There are also many secular works, such as â€Å"Charles and his Warriors†. Bullough tries to separate legend from reality. It seems that while Charles attempted to rekindle an interest in learning and unite various groups into one nation, he never addressed the economic difficulties that Europe faced now that Rome no longer furnished order. Although Charlemagne did devise the system of pounds, shillings and pence used throughout Europe during the middle ages and in Britain until recently, other segments of the infrastructure continued to decline. Roads and bridges fell into decay, trade was fractured, and manufacturing was by necessity a localized craft instead of a widespread and profitable industry. But these are only failures if Charlemagne†s goal was to rebuild the Roman Empire. It is doubtful, however, that that was his motive. Charles was a Frankish Warrior King with the background and traditions of Germanic peoples. He probably succeeded in his goals. Charlemagne treated his empire as his personal property and divided his realm among his sons. Either he failed to realize that only with unity could the empire become a true power, or he placed his own wished, and those of his sons, above the decisions that would best serve the empire. The book is a good source for specific information. It is not a book that I would suggest reading for pleasure. Bullough gives facts and sources but does not stimulate thought. I am sure this book would be great if the reader had considerable knowledge of history. The author makes few direct connections or speculations as to why Charlemagne made certain decisions and took certain actions or the long-term effects of his actions. The author infers most of the conclusions included in this paper in a vague way. At times, I found myself groping for conclusions as to why certain actions were taken. This book provides the reader with hard facts about the Middle Ages in Europe. It does not allow the reader to draw many theories as to the ideas and feelings of the people.

An Exploration Into 14 Bauhaus Books by Lazlo Moholy-Nagy in Relation to Visual Culture Essay

When analysing ‘the 14 bauhaus books’ by Lazlo Moholy-Nagy (see figure 1) in relation to it’s historical context, at least 5 components have to be considered. These are: the image itself; the movement it is part of; the artist, Lazlo Moholy-Nagy, that made it; the bauhaus- the institute it was produced for and where the artist taught – and how these parts have changed or influenced modern times. My argument is that all of these separate components, the main being the movement of Modernism, made life better for the International populations that welcomed it, through the universal progression that modernism once promised. 4 Bauhaus Books is not a ‘pretty’ image. The dirty red mixed with the hard texture of the metal type is not pleasing to the eye for any viewer. But then again it is not meant to be pleasing, the image is a brochure cover, nothing more. Although by todays standards it is crude in design, vaguely relating to the brochure that it covers, which does go into detail about some new typographical forms, it was rather advanced for 1929 as it was a Modernist piece – rejecting decoration. No longer focussing on decoration produced a new language of design that could be understood by everyone, including workers in modern industry. Moholy-Nagy followed his own teachings on typography fully, stating that: â€Å"Letters should never be squeezed into an arbitrary shape†¦ like a square. A new typographic language must be created combining elasticity, variety and a fresh approach to the materials of printing†¦. † (Naylor, 1968, p. 127) This approach to communication through printed material can still be seen today, particularly in adverts which have a very short amount of time to impact on and communicate to an audience. A ‘stand-out’ type coupled with a few witty lines has found itself at the centre of most printed advertisements today (see figure 2), which, it could be argued, can trace it’s heritage back to the modernists ideas of simplicity. We are all now accustomed to this, but back in the early 1900s it was met with fierce opposition and, although new aesthetics were being created, official designers and architects preferred to follow the word of Ruskin who stated: â€Å"We want no new architecture†¦ The forms of architecture already known to us are good enough for us, and far better than any us† (Naylor, 1968, p. ) This narrow-minded approach to design held back progress and kept Europe’s standard of living the same, which, especially for the working classes, was unacceptable. From this, modernism rejected the historical styles before it, such as the Enlightenment phase, that focussed on decoration and perceived that ‘greatness lay in the reconstruction of the past’. Instead modern designers, in the smoke of the Industrial Revolution, created a new style – the ‘International Style’. The ‘International Style’ had called for change and the change was to blur the class distinctions. The â€Å"millions of†¦ home-owners†¦ painted their walls beige† (Greenhalgh, 1990, p52) in an attempt to fit in with this style. This cheap method of interior design, using hardwood for fittings and mass produced light fittings made the ‘International Style’ available and popular. Modernism created objects that functioned with little or no decoration. These objects were mass produced,widely available and more importantly cheap to purchase. For example the Tefal kettle (see figure 3) which has only the water gauge projecting out of a white block for decoration. This simplistic approach to design was, in the eyes of the modernists, an enhancement of purity. The same could be said for ’14 books’. That it’s simplicity is it’s decoration and that the text is the ‘object’ needed for its design purpose. Something functional yet visually satisfying. Modernist designers used the technique of abstraction in their work to help convey a visual trend and to combine the three areas they believed to be true design. This was architecture, furniture and graphic design. Abstraction meant that modernists could use ideas found in a particular building or a colour palette from a painting to create solid habitable homes or items for these homes. A well known example for this is from the painting of Mondrian – composition in red and blue (see figure 4). This was abstracted by the designer Rietveld to create a home (see figure 5) and a chair (see figure 6). Both of which the user had to engage with, as the world had gained a passive lifestyle – the chair was designed for better seated posture and the home bragged fold out compartments, tables and beds so that living was a conscious decision. Unfortunately the chair was not mass produced and only a prototype as there was â€Å"not enough interest in it, as it was not comfortable to sit in† (retrieved on January 10, 2011, from www. contemporarypractice. wordpress. com). This abstraction was seen as a rational use of design, using one ‘useful’ item aesthetics to create another and was used by most modernist designers. The downside to this would be that everything lacked spontaneity. Supposedly a unique series of furniture could look like another, but modernists did not mind this, as they wanted everyone to be equal. The Bauhaus, of course, was the school of modernist design in Europe. It symbolised new technologies and ideas for teaching. Even the building (see figure 7) was a modernist piece. The building had no decoration except for the glass sheets that covered it, which itself was a relatively new item, having been invented in 1832. Glass sheeting, ironically, was used in the crystal palace, which was a celebration of the aristocracies achievements, the opposite message of modernists to â€Å"†¦ reate a new guild of craftsmen, without the class distinctions which raise an arrogant barrier between craftsman and artist. † (Naylor, 1968, p. 9) This quest for the combination of form and function is, in my opinion, found in Josef Hartwig’s 1924 chess set that has, instead of the traditional figures, pieces that consist of geometric shapes (see figure 8). The design of each piece shows how it moves- for example the 2 diagonal lines that make the bishop’s cross show that i t is constrained to diagonal movement. The negative side of this simplicity was a lack of emotion in all creations, as well as an impersonal approach to design. These made the masses feel common, which did not sit well with the elite of the time, who were used to the decorative forms of the Romantics that preceded them. This was, in many ways the enemy of the Bauhaus, referred to as â€Å"that strange decorative disease†(Naylor, 1968, p. 14). Simplicity was key for the Bauhaus and 14 Bauhaus Books was no exception. Understated colours and the photograph used for the main image how this. The type itself is clear and typical of the Bauhaus. Lazlo Moholy-Nagy taught at this revered school and stressed that â€Å"Typography must be clear communication in its most vivid form. Clarity must be especially stressed, for clarity is the essence of modern printing. † (Naylor, 1968, p. 127)Clarity is indeed expressed in ’14 Bauhaus Books’, where no complex symbolisms or congested space occurs. Lazlo Moholy-Nagy’s views on teaching was as radical as his rules. He sought to rid the preliminary course he took over in 1923 of emotion. He saw the soul as part of the body and not in control of it. This wasn’t welcomed by some of his colleagues and students, who described his arrival as â€Å"a pike in a pond full of goldfish† (Whitford, 1984, p. 128). Moholy-Nagy differed from his predecessor in every way. He wore a pair of overalls and nickel-rimmed glasses, emulating an industrial worker , whereas the former teacher, Itten, dressed more like a monk, with a perfectly shaved head – â€Å"creating an aura of spirituality and communion with the transcendal† (Whitford, 1984, p. 23) – mirroring the enlightenment movement that modernism rejected. Moholy-Nagy was to cast out everything irrational in his course. Instead he focussed on teaching techniques and a wider variety of media, stating that: â€Å"anyone who knew nothing about photography was a kind of visual illiterate, and that an artist who restricted himself to any single media should not be taken seriously. † This can be seen in ’14 Bauhaus Books’, where a variety of media is used. The combination of photography, graphics and type give the design a very individual feel. For although Moholy-Nagy insisted he used no emotion, one can’t help but feel a personal aspect behind this cover, a contradiction to his own rule. Moholy-Nagy’s link with industry spilled over to an infatuation with the machine. The machine to him was ‘the’ invention of the century, replacing the transcendental spiritualism of past eras. He saw it as the way to gain equality for the masses. Stating that: â€Å"Everyone is equal before the machine†¦ There is no tradition in technology, no class-consciousness. Everyone can be the machine’s master or its slave. † (Whitford, 1984, p. 128) Using the machine as a figurehead, Moholy-Nagy, along with other modernists and constructivists bettered the world. The change brought about by modernism was huge. As the movement grew in popularity all classes changed their way of living. They were boxed in with hardwood fittings and lived in a functional, conscious home. These homes would later be criticised for being to small and impersonal, but at the time they were considered ‘the modern home’. It wasn’t just the home that was improved through modernism. Factories over Europe America and Asia used more and more machinery, quickly churning out more products in a day than a craftsman, what had come before, could produce in months. This led to more jobs, fewer costs and a better standard of life for everyone. Though this also was met by criticism: that the worker had become non-human, â€Å"an appendage to the machine† (Greenhalgh, 1990, p. 54). The fact that people worked 10-12 hour shifts to maintain their lifestyle did not sit well. Marxists stated that industrial work meant that â€Å"Man is alienated from other men. † (Greenhalgh, 1990, p. 54) It could be argued that the limitations and ideas set in place for this simple graphic design, which is rather crude by today’s standards, has helped the international masses. The change that came about because of the movement of modernism, along with Moholy-Nagy’s approach to design and the new tuition in the Bauhaus of a generation of architects, furniture designers and graphic designers has helped to shape the world of today. Modernist buildings fill today’s cities, from huge skyscrapers consisting of tons of glass, such as the Seagram Building, New York (see figure 9), to mass housing, that was and is cheap, yet functional. This International Style that ’14 Bauhaus Books’ boasts to belong to a collection millions of posters , magazine covers, and furniture designs. Always with its’ main aim to better daily life through technology, for â€Å"not the product the but man is the end in view† (Naylor, 1968,p. 156).

Malware - Essay Example In this case, the malware is used to track and gather statistics and information. Malware have the ability to run without being shutdown, detected or deleted. Malware such as Adware has a privacy invasive characteristic. In this case, the malware displays, plays and downloads advertisements automatically. Malware such as Backdoor have secure remote computer access characteristics. In this case, they can circumvent regular authentication processes (Aquilina, Casey & Malin, 2008). Malware usually infect a computer through executable software. They target a system without the authorization or consent of a user. Running a software or system that is infected by a malware provides opportunities for the malware to spread. A malware needs a user to run an infected system or program in order to facilitate its spread to other executables (Dunham & Abu-Nimeh, 2009). For instance, the Valentine’s Day virus is spread when a user opens an email that has been infected with the virus (Skoudis & Zeltser, 2004). Users are usually compelled to open these emails because they have enticing messages. The aim of the virus was to spread in the computer and capture financial and personal

Economics of the Environment Essay Example | Topics and Well Written Essays - 2250 words

Economics of the Environment - Essay Example Particular issues include the cost and benefits of alternative environmental policies to deal with air pollution, water quality, and toxic substances, Solid waste, and global warming (Hanely, Shogern & White, 2001). Some of the major projects, which have substantial environmental impacts, is Afforestation of Surplus agricultural land, hydroelectric schemes, Building, or widening roads, constructing a new Airport and Manufacturing cars. All the above projects are likely to generate substantial Environmental costs and/or benefits, and they can be considered as Potential Investment. Potential Investment: A Potential Investment can be defined as the Investment made by an investor for growth (profit) of his/her investments in a firm or in a project. Investors look for evidence that, we can really produce growth in our project, and they look for three important things before investing, excellent growth potential, exceptional return on investment, up to 25% to 45% and a way to get their mon ey out. We have to show them how our opportunity will deliver all three, and doing so will be a potential investment made by an investor in our firm or in a project. A Potential Investment can also be a huge project, which has a substantial impact on the environment. It can be a Hydroelectric project, Afforestation project, Building or widening roads, constructing a new airport, and Manufacturing cars. As these projects, have many impacts such as on environment, for profit of an investor, public convenience and many more. When a project is been started, they are many calculation done for different purpose, such as profit, low initial cost, higher efficiency of the project, easy maintenance, etc... In addition, for doing such calculation different numerical, theoretical, ratio analysis and analytical methods such as CBA (cost beneficial analysis) and CEA (cost effectiveness analysis) are been use. For this assignment, we select Afforestation of surplus agricultural land as our major project, which deals with planting of trees on land that did not carry forest for centuries, i.e. Afforestation is a clear shift in land use of a certain area. Afforestation in form of planting trees and future maintenance is an investment for landowner, and possible forgone revenues from Agriculture need to be included. Afforestation of former arable land will have many positive environmental effects. The change from agriculture to forestry means less input of pesticides and Fertilizers that may possibly leach to ground water reserves and the establishment of habitat for species associated with forest. Forest's also able to better retain nitrogen from arable use in the ecosystem, thereby avoiding eutrophication of water reserves. In this paper, we show how CBA can be used as a decision support mechanism for the location of new (urban) forestland, starting from the multifunctional role of these new forests. We start with a simple presentation of the Cost-benefit analysis (CBA) technique. Key features of these evaluation techniques are that (i) assess the monetary value of all benefits and cost (ii) the issue of discounting and (iii) the decision rules used in CBA. Finally, we apply the CBA to a real life policy problem. We investigate the net benefits per Hectare of combinations of potential forests that meet the surface restriction of 540 ha. We show the importance of including recreation benefits in the evaluation of afforestation projects and more specifically the role of alternative forests (substitutes) in the valuation of one specific Forest. We find that this substitution effect is significant in the decision

Law of Evidence Essay Example | Topics and Well Written Essays - 2500 words - 4

Law of Evidence - Essay Example As a result, three recognizable problems can be established. First, the impact on the European Convention of Human Rights on the statutory provisions which seem to offer expressly for a burden of proof that is to be placed on a defendant. The second problem is that whether such burden has ever been placed on a defendant in a criminal trial. And, thirdly, if it possible to inform if Parliament has, in a specific statute, impliedly placed such a burden on a defendant3. Where the issue of implied reverse burden of proof arises by way of statute, it needs to be compatible and given effect with any rights protected under the Article 6(2) ECHR4. The Human Rights Act 1998 (HRA 1998) is where the Convention actually integrated into English laws5. A legal burden of proof is also known as ‘persuasive’ burden of proof. The persuasive burden of proof is the responsibility that is vested on only one party and ought to be satisfied so as to win in any specific issue in question. In that perspective, in some criminal trials, only one party bears the burden of proof on some issue and a different party on others. A discussion that relates to the legal burden of proof in any specific trial usually makes no sense unless that burden is related to a particular issue of fact. It is really very important to establish that the guilt of the accused is for the prosecution to prove and remains there all through the trial as in Woolmington v DPP6. Adrian cited that a legal burden is a burden of proof which a standard of proof can actually be assigned but saved in the case where the defendant needs to establish his insanity upon a balance of probabilities and of defence of insanity. In some instances, a ‘reverse legal burden’ is placed on the defendant7. Donnellan argued that reverse burden procedures usually arises when the statute that creates the criminal offense imposes a legal burden on the

His call for conscience must initially start from cognizance of man’s acts and how it affects the ecology. 2. In its entirety Rachel Carson writes a very poignant essay which illustrates a perceptible recognition of her predisposition which is noticeably literary. â€Å"All through the night the cries of curlews and plovers and knots, of sandpipers and turnstones and yellowlegs, drifted down from the sky. The mockingbirds who lived on the island listened to the cries. The next day they would have many new notes†¦Ã¢â‚¬  (Carson, 1941). This passage stuck to me in a way that it evoked a deep sense of poetic beauty that signifies symbolic representations while at the same time realistically narrating something that is actual and tangible. The connotations of the night proved to be consistent in this passage with the birds howling at night that suggests they are probably in misery over something. The mockingbirds represented the role of a spectator much like the reader who are there only to witness them but without any active part in the process. But as far as symbolisms would go, a new day would present a new beginning and a new hope that was equally appropriate for the birds. 3. There had always been an attribution of enchantment and an implication of beauty toward flowers. This gift of nature in different forms, shapes, sizes and smells evoke a profound feeling that is often romanticized as perpetuated by poets and the like. The reverence given to flowers had always been reinforced by society. Flowers, depending upon the circumstance, may imply love, sympathy, respect or delight. The next quotation signifies a stripped version of man and all of his ingenuities as by-products. But in essence, it is nature that is the

I declare that I have wholly undertaken the study reported herein under supervision Essay The Lord has been faithful in granting me the strength, wisdom, knowledge and the courage needed throughout the period of study. My sincerest appreciation goes to my supervisor, MR. MICHAEL NKONYAA for his guidance and constructive criticism through the preparation of the work. He is largely responsible for the success of this work and I am very much grateful. To my husband Solomon Kweku, to my colleagues in MBA Finance 2012/2013 in whose company I stayed and formed my thoughts I say God richly bless you for the fellowship and love we shared. To the Staff and Management of Growth Capital Microfinance, wish to express my sincere gratitude to you for your support and co-operation. Finally, I wish to thank all authors of various research works and articles I made use of in writing of this work, indeed, your research works and articles have served as major sources of literature and knowledge. ABSTRACT This study examined effects of microfinance on small and medium enterprises in the Accra Metropolis, in the Greater Accra Region. .The population of the study comprised clients and staff of Micro finance Institutions (MIF). A sample of 60 clients and eight staff was used for data collection. Two interview guides were used separately to collect data from staff and clients. The return rate of data collection was 8(100%) for staff and 55(91.7%) for clients. Data collected was analysed manually and electronically. The statistical product and service solution (SPSS) was used for the electronic analysis in which descriptive statistical tools were used for data presentation and discussion. Results of the study indicated that microfinance s impacted positively on the social and economic lives of SMEs operators. The research also indicates that MFIs have had a positive effect on the growth of SMEs. Some of the critical contributions of MFIs include; greater access to credit, savings enhancement and provision of business, financial and managerial training. Irrespective of the contributions of MFIs to SMEs, there are challenges that affect their operations of both SMEs and MFIs. The major challenge faced by SMEs is the cumbersome process associated with accessing credit of which collateral security and high interest rate are major setback. The MFIs on the other hand, face some challenges relating to credit misappropriation and non-disclosure of the relevant facts of their businesses. In the final analysis, the research clearly reveals that MFIs have a positive effect on the growth SMEs. In other to enhance a sustained and accelerated growth in the operations of SMEs credits should be client-oriented and not product- oriented. Recommendations were made to MFIs, Specifically, MFI was asked to put in measures that could help reduce interest rates, train operators of SMEs on proper business practices Proper, extensive monitoring activities should be provided for clients who are granted loans and SMEs were asked to adopt effective bookkeeping modalities.

Effect of the Recession on Sustainable Development

Effect of the Recession on Sustainable Development Sustainability has been on the lips of everyone involved in the construction industry for the last 10 years. However, the issue of Sustainability arouse first in a Report named Our Common Future. This then prompted the need for the conference in Brazil (1992). Discussed in this conference were the core principles of sustainability being; Development that meets the needs of the present without compromising the ability of future generation to meet their own needs Greene, D. (1997) Both Sustainability and the Recession are both terms in which have a range of meanings and attitudes. As the issue of Sustainability is being used more and more in the construction industry is recent years it is imperative to try and pin point exactly what sustainable commercial construction is. It is also paramount to determine just exactly what the recession is and show just how they have affected each other. In recent years, we have had two previous recessions, one being in the 1980s and the second one being in the early 1990s. This is the third recession that the country has been in, in as many decades. In June 2008, the country officially entered the third recession, of which we are still in today, Sustainability has become more of a problem in recent years due to the major issue of the recession. Sustainability needs to be addressed and identified and it is important that it is done within one of the largest industries, if not the biggest, being the construction industry. In my research I will hopefully try to clarify the terms, sustainable commercial construction and the recession and show how each one has affected the other. Keywords Sustainable Commercial Construction; Recession; Introduction One of the main priorities for the construction industry and any construction company are to produce Sustainable Commercial Buildings. As everyone knows, the country has been hit by a recession with the construction industry being hit the hardest. It is important to define exactly what Sustainable Construction in commercial buildings is and exactly what the recession is and see just how the recession has affected Sustainable Commercial Construction 1.2 Aim In this dissertation I aim to investigate exactly what the recession is, exactly what sustainable development is and I aim to show the audience just how each one has affected each other 1.3 Project Objectives To define the recession To define sustainable construction To determine just how the recession and sustainable construction have been affected by each other. What barriers or influences encourage or deter companies to build Sustainable Commercial Buildings. 1.4 Proposed Structure 1.4.1 Background First of all the research will define both the recession and will also define sustainable construction and go on to look at how they have been affected by one another. The research should then go on and look at what barriers or influences encourage or deter companies to build Sustainable Buildings. 1.4.2 Collection of Results The collection of results will be accomplished using professionals who are currently working in and around the construction industry. Results will be collected with information regarding their views on whether Sustainable Construction has been affected by the Recession and other information regarding Sustainable Construction. 1.4.3 Analysis The results collected from my interviews will then be analysed so that an outcome can be gained to answer the investigation objectives pointed out earlier. They will also be analysed to show a comparison with past research relating Sustainable Construction and the Recession. 1.4.4 Final Analysis The final analysis is the last part of the research, like a conclusion it will assess the data to check and make sure that all aspects of the investigation have been covered. The investigation will then be checked to make sure it cannot be improved and revisited. Sustainable Commercial Construction and the Recession Scope of the Chapter This section of the dissertation will determine the definition of Sustainable Commercial Construction and will also try and determine just exactly what a recession is. 2.2 The Recession In June 2008 the United Kingdom officially entered the recession that we are still in today. The main area that has been affected in this country and many other countries is construction, which has been hit massively. Companies and businesses right across the board are being affected from big names such as Balfour Beatty, the Kier Group down to small independent companies. Any sort of work is few and far between nowadays with every company accepting any sort of work no matter how small or big it is. I feel that this topic as it will show you past the commercial side of the recession. Everybody knows that the country is in the recession, but not that many people know exactly what a recession is and what damage it can cause to the economy and the country. It has a massive knock on affect right the way down the board and I believe that if we are going to get out of the recession quickly and efficiently people need to know how to adapt and work with it. The recession is not very well understood for one simple factor: There is not a universally agreed upon definition. There is a standard newspaper definition of a recession is a decline in the gross domestic product (GDP) for two or more consecutive quarters. There are 4 quarters to the year and each one lasts for approximately 12 weeks. This definition is not popular with most economists for two main reasons. Firstly, this definition does not take into account changes in other variables such as unemployment rate or consumer confidence. Secondly, by using quarterly data this definition makes it difficult to pinpoint when a recession starts to when it ends. The second definition is from the Business Cycle Dating Committee (BCDC). The committee provides a better way to find out whether or not there has been a definition as they determine the amount of business activity in the economy by looking at, employment, industrial production, real income and whole-sail retail sites. The past 20 years has been a growing realisation that the current model of development is unsustainable and basically, we are living beyond our means. Before anyone knew anything about this current recession, one part of construction that was on the rise was sustainable development. It is rumoured that one of the key factors in which the recession was brought on is that companies were being too selfish in that they were thinking about the short term rather than the long term. Some unsustainable business practices were concerned about profiteering and not focused enough on balancing profit with social and environmental targets. With the current economic crises being the way it is, companies are rarely willing to spend money on anything but essentials to their business. The credit crunch has virtually halted all new development and with falling land prices, affordability has become more important than ever, thereby highlighting development costs and the increased expense of complying with sustainable standards. Ultimately crucial issues related to sustainable development such as healthcare, education, affordable access to food, water, energy and responsible harvesting of natural resources are being affected as the crisis deepens. The increasing stress we put on resources and environmental systems such as water, land and air cannot go on forever. The need for Sustainable Commercial Development is too great to be ignored. Even in this recession and the state that the economy is in it is absolutely paramount that we as a country, continent and as a human race continue to develop sustainably. Instead of businesses thinking of their short term future, they now need to be thinking about their long term future. Instead of reeling in the cash straight away, we need to hold out and wait for the return from sustainable buildings and development all round. The sooner people and companies realize this, then the sooner the construction industry will have left the recession and will be planning for the future and sustainable development wont be a thing upon which businesses sigh about doing, it will become the first thing they think of. 3.0 Sustainable Buildings Sustainability in building was completely unknown up until around the late 1970s. The idea only came about in reply to the energy crisis and people concerned about the environment. There are not many people in this country or the world in fact who will not have heard the word sustainability but the vast majority of them will not understand what it means. According to Holmberg and Sandbrook (1992) there now appears to be 70 definitions in circulation. However, out of these 70 or so definitions that are circulating there is no definite, set definition of sustainable building but according to Kirby et al (1995) the definition which is commonly deemed as the most accurate or the official one is the Brundtland definition (WCED 1987) development that meets the needs of the present without comprising the ability of future generations to meet their own needs. Although, Brundtland did make this definition, it is an adaption of a previous definition made by Lester Brown. Lester Brown however defined a sustainable society, rather than sustainable development. He defined a sustainable society as one that is able to satisfy its needs without diminishing the chance of future generations. (Charles J Kilbert 2008) It is easy to see the comparisons between the two definitions made firstly by Lester Brown and secondly, the Brundtland definition. Although the Brundtland definition is the most common and widely used, it doesnt define sustainable construction, only sustainable development. According to Dickie and Howard (2000) they describe sustainable construction as the contribution of construction to sustainable development. This definition from Dickie an Howard (2000) is very simple, but explains a lot, anyone would be able to understand it. ORiorden (1985) commented on the difficulty of describing sustainability, describing its definition as Exploration into a tangled conceptual jungle where watchful eyes lurk at every bend. This description of how hard and elusive it is to describe correctly what sustainability just shows you how vague and confusing defining sustainability can become. sustainability is like plumbing or air conditioning its a general attitude you apply to a building. It doesnt create its own architecture but it informs the way architecture is produced Slavid, Ruth (1998) uses this definition and its obvious that there are not only different definitions but also different meanings to the definitions. According to Addis, B and Talbot, R (2001) Sustainable development is about achieving economic and social objectives while minimising adverse environmental impacts This definition comes from the e-journal; Sustainable construction procurement: a guide to delivering environmentally responsible projects by Addis, B and Talbot, R (2001). As you can see all the definitions on this page and the previous page all define sustainable construction, development or sustainability on the whole, and they are all pretty much nothing like each other. Although there have been many definitions of sustainability for example that from the World Congress of Architects (1993) Sustainability means meeting our needs today without compromising the ability of future generations to meet their own needs Even though all the definitions above are different you can see a definite trend between them. I believe they are all loosely based on that from the Report of the World Commission on Environment and Development: Our Common Future. This report is commonly known as The Brundtland Report. Some people may believe that having no definition for sustainable development could be an issue because how are people meant to implement and deliver sustainable development and in this case sustainable construction if an official definition has not been agreed. 3.1 Case Study To help what is understand what is involved in Sustainable Commercial Construction, a case study will be used. Whitecross High School, Hereford, England Owner: Herefordshire County Council Address: Three Elms Road, Herford, Herefordshire Architect: Haverstock Associates Building Services Consultant: Couch Perry Wilkes Contractor: Stepnell LTD Figure 1 Image of Whitecross High School, Hereford, England Whitecross High School in Hereford was primarily designed where energy / sustainability was high priority for the client. The gross internal floor area of the school is 9160m2 and was built for approximately 900 students. The brief for the project contained stringent sustainability requirements, and this became the key driver for the design process. Sustainable features of Whitecross High School: High mass and thermal insulation levels with low air permeability rates Excellent air quality and summertime temperature control Heat recovery ventilation 90% efficient Very Low annual energy consumption Sustainable solutions provided within PFI cost framework Natural materials used throughout construction Hazardous materials excluded from the building specification Following the case study, we can see at the Whitecross High School that not only is there sustainable energy solutions in this sustainable building but there have been solutions designed in the buildings. For example the excellent air quality and summertime temperature control system means that other expensive and unreliable systems would not be needed, saving time and money on the sustainable building. You can tell by the number of definitions and the lack of agreement of an official definition about the subject of sustainability and sustainable construction is confusing and complex. The main disagreement is apparent around how to implement sustainable construction what systems actually make a sustainable building, sustainable. 4.0 Research Approach 4.1 Scope of the Chapter This chapter of my dissertation will outline the research methods used to complete my dissertation. It will compare the two different types of research and will also show why I have chosen my specific method. 4.2 Qualitative and Quantitative Research When researching for any type of information there are different methods that can be used. There are two principal strands of data collection methodologies and strategies which are distinctly different. (Bryman 2004) Quantitative research involves the use of structured questions where the answer are predetermined, this research is done over a large number of respondents and is statistically valid while qualitative research is about collecting and analysing data interpreting what people say or do for instance a questionnaire. The very nature of the dissertation, the different types of information needed in order to achieve the objectives and the resources that are actually available like time implications for instance affects what types of research methods will be used. To gain a wider perspective about sustainable development and about the current recession period, it is always a good idea to do some research within the public, using both primary and secondary research. There are many different types of research that you could do, some of which are quantitative and qualitative approaches. Usually research methods and styles are not mutually exclusive although only one, or a small number of approaches, will normally be adopted due to resource constraints on the work. The different approaches focus on collection and analysis of data rather than examination of theory and literature. Quantitative approaches normally seek to gather factual data, studying relationships between facts and how such facts and relationships accord with theories and the findings and of research carried out previously. Qualitative approaches seek to gain and understand peoples perceptions, both as individuals and as groups. This research looks at peoples beliefs, understandings, opinions and views etc are investigated. The data is detailed and rich in content because the data gathered may be unstructed, but will be in their raw form. If you do use this method of research you would have to be willing to be highly laborious, involving transcripting interviews etc. The researchers are likely to be closely involved in all stages of the work in a more active way than usually is acceptable in quantitative studies. Features of Qualitative research Features of Quantitative research Difference in respect to: Quantitative Research Qualitative Research The aim is a complete, detailed description. The aim is to classify features, count them, and construct statistical models in an attempt to explain what is observed. Underpinning philosophy Rationalism: That human beings achieve knowledge because of their capacity to reason (Bernard, 1994) Empiricism; the only knowledge that human beings acquire is from sensory experiences (Bernard, 1994) Researcher may only know roughly in advance what he/she is looking for Researcher knows clearly in advance what he/she is looking for. Approach to inquiry Structured/ rigid/ predetermined methodology Unstructured/ flexible/ open methodology Recommended during earlier phases of research projects Recommended during latter phases of research projects Main Purpose of investigation To quantify extent or variation in phenomenon, situation, issues etc. To describe variation in a phenomenon, situation, issue etc. The design emerges as the study unfolds All aspects of the study are carefully designed before data is collected Measurement of variables Emphasis on some form of either measurement or classification of variable. Emphasis on description of variables Researcher is the data gathering instrument Researcher uses tools, such as questionnaires or equipment to collect numerical data Sample Size Emphasis on greater sample size Fewer cases Data is in the form of words, pictures or objects Data is in the form of numbers and statistics. Focus of inquiry Narrows focus in terms of extent of inquiry, but assembles required information from a greater number of respondents Covers multiple issues but assembles required information from fewer respondents Subjective individuals interpretation of events is important ,e.g., uses participant observation, in-depth interviews etc. Objective seeks precise measurement analysis of target concepts, e.g., uses surveys, questionnaires etc Dominant research value Reliability and objectivity (value-free) Authenticity but does not claim to be value- free Qualitative data is more rich, time consuming, and less able to be generalized.ÂÂ   Quantitative data is more efficient, able to test hypotheses, but may miss contextual detail. Dominant research topic Explains prevalence, incidence, extent, nature of issues, opinions and attitude; discovers regularities and formulates theories Explores experiences, meanings, perceptions and feelings Researcher tends to become subjectively immersed in the subject matter. Researcher tends to remain objectively separated from the subject matter. Analysis of data Subjects variables to frequency distributions, cross-tabulations or other statistical procedures Subjects responses, narratives or observation data to identification of themes and describes these Communication of findings Organisation more analytical in nature, drawing references and conclusions, and testing magnitude and strength of relationship Organisational more descriptive and narrative in nature Figure 2 Table adapted from www.wilderdom.com and Kumar (2005) The features of qualitative and quantitative research methods along with the differences in the two methods can be seen in Figure which has been adapted from www.wilderdom.com and Kumar (2005) The table shows the two different research methods that can be used and their advantages and disadvantages. It shoes the features of both Qualitative Research and Quantitative Research. 4.3 Research Design There are several different ways that the research for this project could be undertaken and when looking at the most suitable method. There are three major factors that are the most significant amongst the others that need to be taken into account. They are; Reliability Replication Validity These three factors that have been identified are all issues that could affect the consistency, therefore the reliability of the data for my dissertation 4.4 Approaches to date collection 4.4.1 Interviews Interviews have been described by Kumar (2005) as being person to person interaction with specific purposes. There are two main types of interviews and these can be seen in figure below taken from Kumar (2005, page. 123) Interview Styles Unstructured Structured Flexible interview structure Rigid interview structure Flexible interview contents Rigidy interview, rigid interview contents Flexible interview questions Questions and their wording Figure 3 Diagram showing the two possible interview techniques The advantages and disadvantages of interviews have been identified in the table below. Advantages of Interview Disadvantages of Interview ÂÂ   More appropriate for complex situations Can be expensive and time consuming Interviewing has a wider application Interviewee could be bias Questions can be explained Quality of information may deteriorate Good for in depth information Quality of interviewee may be poor Face to face interaction Quality of data could differ on interaction Figure 4 Advantages and disadvantages of the interview 4.5 Research Proposal Because of my dissertation, and what it is involving, it was not feasible for me to produce any quantitative data as the majority of the general public will have very limited or no information whatsoever about my chosen subject. Therefore my research method was a set of self designed research questions used to gather honest and first hand information, about the effects the recession is having on commercial sustainable construction. The purpose of this interview based approach was to abstract through questions the information needed to answer the research question. Tesch, (1990) defines qualitative research as Intensive study of one individual or a group as an entitiy, through observation, self-reports and any other means. In this case the individual was interviewed alone, yet was also grouped together in order to distinguish any inter related experiences. 4.6 Sampling It is clear that to get the best information possible, a wide range of professionals needs to be used. I therefore opted to use professionals from different backgrounds to interview. The professions in which I used are; Building Surveyor Life Cycle Director Commercial Sector Director Senior Design Manager The reason for selection of the professionals is that hopefully I can gain an insight into the different views on the set of self designed questions that have been prepared for them. I was careful in choosing the professionals in which I did. I wanted to gain the best information possible to obtain the best results for my dissertation. I decided on choosing professionals who are well established in their different fields and have a wide vocabulary of knowledge, and in some cases, have plenty of experience. 4.7 Interview Design I decided in order to gain the best and most accurate information it would be best to have a structure interview. Therefore I would take a set of pre determined questions into the interview and asked to the professionals. The advantages of such a structured interview would be that each and every one of the professionals would be asked the same questions then a better analysis could be gained as their responses are all to the same questions 4.8 Summary The above chapter covers the whole process of collecting data and the means for it to be compiled. 5.0 Data Collection Activities 5.1 Scope of the Chapter This chapter in hand looks at the activities that took place in order for me to successfully collect the data. The data collection activity covers what was completed to collect the resulting information and the processes that have taken place. The following chapter should show the results collected, which be analysed according to the objectives. 5.2 Data Collection The only source of data collection was conducted using structures interviews. The interviews were recording on different days, but in the same week as I deemed it important as it would give me the most accurate information. The professionals all gave a good sample of answers to the questions given to them. The interviewees were of a high professional level and of high standard. 5.3 Interview Results I considered it was important to correctly select the amount of the actual questions I would be asking. This was for the simple reason that it would give me the best and most accurate answers about sustainable commercial buildings, the recession and whether or not they have had an effect on each other. Independant Variables I deemed it necessary to find out the age of the interviewees, the years of experience they have in the necessary feild and more importantly what their profession was. Age of the interviewee Figure 5 shows the age of the participants Amount of experience in current profession Figure 6 shows the amount of experience each interviewee has What profession the participants are in Figure 7 shows the profession of the interviewees 6.0 Data analysis 6.1 Scope of the chapter In this chapter I will critically analyse the results that were compiled from the interviews that were undertaken. The results will assess the impact that the interviews have had upon the research completed, and will compare or contrast findings. The way in which I will be analysing the interviews is by looking at each question, explaining each of the results and from there, I will be analysing them. Question 01 Analysis Do you utilise in-house staff rather than specialist consultants? Results You can see from the transcripts that the interviewees have answered the question, with different opinions. Interviewee 1 and Interviewee 3 both say that they use both in-house and specialist consultants. Interviewee 3 then goes on to say that the main reason they are using in-house staff rather than specialist consultants is that they are much much cheaper. Interviewee 2 and Interviewee number 5 both have the same sort of answer. They both said that they try to use specialist consultants rather than in-house staff in their companies. Interviewee number 2 explained it was because contractors are seeing the need for specialist advice that can help them differentiate in a competitive market; to have an edge and make sure they win the tender. Interviewee number 4 however, said that in his company they try to utilise the in-house staff as much as possible but because the company in which he is employed by is fairly small company compared to the Balfour Beattys, Carillions and other such companies.. Analysis From this question, I have a mixed bag of answers to whether companies use in-house staff or specialist consultants. Because of the varied answers, I believe that some companies are doing better in the recession than other companies and still can afford the specialist consultants. I also believe from the answers that some people believe it is more important to gain the specialist knowledge than it is to use in house staff as they believe using in-house staff hinders your chances of winning a contract when tendering for it so having the best knowledge possible is key. Questions 02: Analysis Has the amount of contractors being tendered to changed since the recessional period started? Results I can see from the transcripts there is a popular answer to this question. Interviewee numbers 3, 4 and 5 all agree that there has been some change in the amount of contractors being tendered too. Interviewee 1 the Senior Design Manager is alone when saying that there has been no change. He explains because Balfour Beatty is a big big company they have a local supply chain in every major area. He explains that at Balfour Beatty they use contractors that they have had previous relationships with because you get better quality out of them. Interviewee number 2 is also alone with his answer. He states Tender lists are long, but I am not too sure at the moment if this is better or worse than before.. At the moment, he is unsure as to whether having long tender lists is better or worse than before. He then goes on to state a main problem with long tender lists is that contractors dont want to spend money on sustainability advice if they only have a low win probability. Analysis There is a common answer among the professionals about the amount of contractors being tendered too. The two Building Surveyors and the Life Cycle Director all believed that there has been some change since the recession started. This tells me that the building surveyors definitely believe that there has been a significant change in the amount of contractors being tendered too. The Senior Design Manager (Interviewee 1), whom I believe is the professional with the most experience, is completely alone with his answer. This in my opinion is because he works at one of the largest construction companies in Europe. Although the recession would still have had an effect on Balfour Beatty, I believe they would not nearly be as affected by is as some of the smaller companies in the industry. The Commercial Sector Director (Interviewee 2) doesnt really give a definitive answer to the question; he just states that the tender lists are long. Question 03: What financial arrangements have been put in place depending on sustainability? Results When asking this question you can see from the transcripts that there was a very popular occurrence of and around the term BREEAM Excellent Interviewee numbers 1, 2, 3 and 4 all mentioned the word BREEAM. Interviewee 1 said I think if affected by the recession but its actually probably a very positive time for us he also went on to say if you look at commercial projects whoever is building a commercial project has got to think about their tenant and tenants often look for; is it a sustainable building? So it is actually a marketing tool that we are using now you know to give us an advantage against our opponents so sustainability rath

Climate Change Will Affect Invertebrates And Vertebrates Environmental Sciences Essay

Climate Change Will Affect Invertebrates And Vertebrates Environmental Sciences Essay Global climate change is predicted to cause temperatures to increase by 1.4-5.8ËÅ ¡C by the year 2100. This will likely have a profound impact upon many land animals. Here, four animal groups were selected for review; amphibians, insects, polar bears and birds. Many species will most probably move further north, where conditions will be cooler. Changes in breeding will occur, with many species breeding earlier, as already demonstrated by amphibian and bird species. Higher temperatures are likely to benefit insects, causing higher metabolic rates and increasing their numbers. Alternatively, a warmer future for polar bears doesnt look promising. With rapid loss of sea-ice, many individuals are suffering, as obtaining food is becoming increasingly difficult. Predicting the likely impacts of climate change is complex as each species will be affected differently. Further research is needed to predict the impacts of rainfall patterns and extreme weather events upon the survival of lan d animals. Abstract 2 Global climate change is well under way, with global mean annual temperatures set to increase by 1.4-5.8ËÅ ¡C by the year 2100. This major environmental change has the ability to influence both species distribution and extinction rates. Here, four animal taxa were selected for review; amphibians, insects, polar bears (Ursus maritimus) and birds. Northern distribution shifts are likely to become increasingly common across all groups as species exploit new habitats and seek cooler conditions. Phenological changes will take place such as earlier breeding in amphibians and birds, though it is uncertain about what this will mean for their persistence. Climate-facilitated diseases may influence extinctions, such as Saprolegnia ferax, which causes mortality in amphibian embryos. Higher temperatures are likely to benefit insects, causing an increase in flight-dependent activities. Alternatively, a warmer future for polar bears doesnt look promising. With rapid loss of sea-ice, the body conditions of many individuals are declining, and desperate foraging strategies such as cannibalism have been reported. Predicting climate induced effects is complex as responses will be specie-specific and potential evolutionary adaptations need to be taken into account. Further research is needed to predict the impacts of precipitation and extreme weather events upon the fitness of terrestrial species. 1.0 Introduction Long term global climate change is currently at the forefront of scientific interest. Climatic variation is undoubtedly a natural process, but the balance of evidence available suggests that excessive human activity has been the dominant reason for the recently observed dramatic changes in climate (Telemeco et al, 2009). Records have shown that since the 1970s, global mean annual temperatures have increased significantly, rising by approximately 0.15ËÅ ¡C per decade (Beaumont and Hughes, 2002). It has been predicted that this trend will continue, and global mean annual temperatures are likely to have increased by 1.4-5.8 ËÅ ¡C by the year 2100 (op.cit). Some researchers believe that such temperature rises will be the largest anthropogenic disturbance ever placed upon natural ecosystems (Deutsch et al, 2008). Whilst this warming has received a great deal of attention, changes in precipitation patterns and the frequency of extreme weather events will accompany this temperatur e variation. These recently devised predictions are causing immense concern amongst scientists, because assuming that they are correct, the biodiversity across the globe will be altered significantly. Distribution, the geographical occurrence or range of an organism, is mostly controlled by climate, and therefore, it is anticipated that this will be notably affected in numerous species (Pearson and Dawson, 2003). Studies have shown that global climate change has already taken effect and has been the cause of numerous distribution shifts observed in a variety of organisms during the past 30 years (Thomas et al, 2004). A study carried out by Hitch and Leberg (2006) found that distributions of North American bird species were moving significantly further north, most probably as a result of increasing temperatures. The extent to which animals react to global climate change, whether it be through changing their distribution or reacting in others ways, will depend largely upon several fac tors. The first is the geographical location of the species and the second being the presence of particular biological traits. These traits are related to factors such as genetic make-up, ecology and life history stages, influencing an individuals vulnerability to climate change. Specific traits include dependence upon a particular microhabitat, dispersal limitation due to geographical barriers and low genetic diversity (Foden et al, 2008).Therefore, not all species will respond in similar ways, even when exposed to the same climatic conditions, meaning that the persistence of some species will be threatened more than others. Extinction, due to climate change, will be the likely reality for some species, and it has been estimated that 15-37% of terrestrial species will be committed to extinction by the year 2050 (Thomas et al, 2004). Research is currently very much centred on trying to identify those most at risk and looking for possible ways to reduce predicted extinction rates. Th ough much effort is being made, minimizing the emission of greenhouse gases, primarily carbon dioxide, is the single ultimate action which could save a vast number of species (op.cit). The publication of a growing number of studies regarding extinction in relation to climate change is making humans increasingly aware of the vital actions that need to be taken in an attempt to conserve the earths biodiversity. 1.1 Aims The aim of this review is to evaluate how global climate change will affect the distribution and status of both terrestrial vertebrate and invertebrate species. Status is quite a broad term but in context of biology and hence this review, it primarily refers to conservation status; examining how likely the animal is to become extinct in the future. Predicting the status of an organism is complicated and requires information regarding various aspects of its ecology, such as its habitat, foraging strategy and breeding behaviour. Research concerning a variety of animal groups will be examined, so that a wide range of potential effects across the animal kingdom can be identified. Here, four taxonomic groupings have been selected for review, due to their high vulnerability to climate change and/or high environmental importance. These taxa are also heavily represented in the available literature. The polar bear (Ursus maritimus) has been focused on due to its rapidly changing ice habitat. Insects and amphibians were selected mainly due to their ectothermic nature and are therefore highly sensitive to temperature. Finally birds were chosen due to their close association with climate, especially in migratory species. Although not every animal class has been reviewed, it is hoped that this literature review can provide a balanced evaluation with regards to an area of science which is causing both increased social interest and concern at the present time. 2.0 Amphibians It is widely accepted that amphibian populations are declining dramatically around the globe, with an estimated 43% of the total species currently in decline (Lips et al, 2008). This has prompted a satisfactory number of studies, which have researched the possible factors responsible for amphibian reductions (Corn, 2005). Though climate change as a cause was considered relatively understudied in 2003, it has since received an increasing amount of attention (Carey and Alexander, 2003). Amphibians are terrestrial ectotherms, having life history stages which are very much sensitive to both environmental temperature and precipitation (op.cit). This suggests that they should be highly vulnerable to climate change, but past records have shown that existing amphibians have descended from ancestors that were able to cope with climatic extremes and variability (op.cit). Nevertheless, it still remains highly important to discover if, and how these animals will be affected by global climate cha nge in the future. Understanding links between amphibian distribution and climate change is essential for their conservation, though relatively few studies have investigated this. Girardello et al (2010) undertook a study in an attempt to discover the likely implications of climate change on the distribution of amphibians in Italy. It was confirmed that climate greatly affects species distribution and precipitation plays a crucial role in determining range shifts (op.cit). Negative predictions were made in that the distributions of many amphibian species could reduce considerably. Mediterranean species such as Rana temporaria and those found in mountain habitats are of a main concern, as it was found that their distributions could decrease, despite the fact they may well colonize new areas (op.cit). One of the reasons for this is that many species in these particular locations are highly climate specialised (op.cit). Therefore, any small changes in climate could prove to be damaging in terms of their distributions. Distribution reductions are not only predicted for species in Italy but for those in other countries too. It is expected that the golden striped salamander (Chioglossa lusitanica), native to Spain and Portugal, will constrict its distribution between the years 2050 and 2080 (Corn, 2005). Research regarding 42 amphibian species throughout Europe produced somewhat more promising conclusions. It was found that temperature predictions for 2050 are not likely to be a major threat to this group of animals, and it was also concluded that they can be expected to expand their distribution (ArauÃÅ' jo et al, 2006). This is due to the fact that the warming of northern European areas will create new habitats, which species can exploit (op.cit). However, this will only be possible if the ability to disperse is unlimited. (Figure 1 illustrates the predicted species extinctions with no dispersal/unlimited dispersal in Italy). The involvements of factors which prevent or reduce dispersal, such as habitat loss, will only decrease range size, possibly contributing to amphibian population declines in the future (op.cit). Figure 1 Projected amphibian species losses (no dispersal) and gains (unlimited dispersal) in Italy, Girardello et al (2010). Unfortunately, it appears likely that during the time leading up to 2050, habitats will be further fragmented and destroyed. This does, however, assist current conservation, indicating that to aid the persistence of amphibian species; both existing and potential habitats must be protected and managed in a way that will allow optimum dispersal. Given that the current conservation status of 32% of known amphibian species is either threatened or extinct, understanding their relationship with climate change is vitally necessary (http://www.iucnredlist.org/ initiatives/ amphibians/ analysis). There are various ways in which a changing climate could affect the status of amphibian species, through both direct and indirect methods. For climate to have a direct negative effect, the levels of temperature, moisture and UVB (ultraviolet-b) radiation would need to exceed the lethal limit of a given species (Carey Alexander, 2003). Although recent studies have shown a correlation between amphibia n declines and climate change, there has been little evidence to suggest that amphibians have been subjected to lethal levels of environmental variables (op.cit; Corn, 2005). There are a number of ways in which climate change could indirectly affect individuals. Successful breeding is essential to ensure the survival of any species. It has been suggested that climate change could interfere with reproduction by causing breeding to occur earlier. Tryjanowski et al (2003) found that the first spawning dates of R.temporaria and Bufo bufo shifted 8-9 days earlier between 1978 and 2002; correlating with warmer spring temperatures. This could be both detrimental and beneficial. It may provide more time for growth whilst reducing exposure to UVB radiation (Corn, 2005). On the other hand, it could also cause exposure to extreme spring temperatures (op.cit). Whilst some studies have shown significant trends towards earlier breeding, there have also been a similar proportion of findings conclu ding that climate has no influence upon breeding time (op.cit). Disease has been positively identified as a major cause for amphibian declines, and climate change could potentially facilitate the spread of infectious diseases, causing species to become more susceptible (Lips et al, 2008). Chytridiomycosis is a disease caused by the fungal pathogen Batrachochytrium dendrobatidis, and has been responsible for amphibian extinctions (Carey and Alexander, 2003). However, Lips et al (2008) found no evidence that climate change is the cause behind outbreaks of this disease. The chytrid fungus most likely prefers cooler temperatures and requires an aquatic environment for transmission (Corn, 2005). Therefore, the current trend towards a drier, warmer climate is not likely to encourage outbreaks of this disease (op.cit). A second fungus, Saprolegnia ferax, has been reported to cause mortality in particular amphibian species. Bufo boreas appears to only be susceptible to this pathogen in the presence of UVB radiation. Kiesecker et al (2001) concluded that low levels of precipitation during El Nià ±o southern oscillation years caused the embryos of B.boreas to develop in shallower water. This in turn exposed them to extreme UVB radiation and as a consequence, the fungus caused mortality (op.cit). Although the association between current amphibian declines and climate remains uncertain, future climate change will inevitably provide serious challenges for amphibians. Whilst many of these challenges can be scientifically predicted, predicting how species will react proves to be more complex. Unfortunately, only time will tell which species will survive and which species will fail to persist under the pressure of a rapidly change global climate. 3.0 Insects Insects are the most abundant group of animals on the planet, making up two thirds of all described extant animal species (Stange and Ayres, 2010). Like amphibians, insects are ectothermic so are also strongly influenced by external temperature and other climatic factors. They are extremely important within natural ecosystems due to their position at the bottom of the food chain, and play vital roles in processes such as decomposition and pollination. Insects also have economic involvements, with some species acting as pests and vectors of diseases. Therefore, research focusing on how insects respond to climate change is beneficial for both the natural environment and human economy. Since the 1990s many studies regarding insects in connection to climate change have been carried out (Musolin, 2007). It is expected to exert powerful effects upon abundance, physiology and distribution, with effects becoming more prominent as the severity of climate change increases (Stange and Ayres, 20 10). A change in the distribution of insects has been one of the most frequently reported responses (Musolin, 2007). Those species living in northern temperate regions appear to be expanding their range northwards or moving to higher altitudes (Maes et al, 2010). Such shifts in distribution have been recorded in a vast number of species. In the year 2000, the distribution of the Southern green stink bug (Nezara viridula) in Japan was found to have moved 70km further north of that recorded in the early 1960s (op.cit). Other Heteroptera species, such as those living in Southern Europe, have been recently discovered in the north, probably as a result of climatic variation (op.cit). In Britain, species of Orthoptera have also extended their range. The unusually warm summers of 1989/1990 caused the distribution of the long winged conehead (Conocephalus discolor) in north-western Europe to progress north and east (Cannon, 1998). The distribution of Lepidoptera has been well documented, ow ing to this groups high fecundity and dispersal ability, allowing distribution to be followed over a relatively short time period (Roy and Sparks, 2000). Observations of Lepidoptera species have been carried out for over 20 years in Finland and prominent northern range expansions have been recorded (Stange and Ayres, 2010). With many distribution shifts having already occurred, it is relatively easy to predict how a warmer future will affect present insect distributions. Range expansion towards the poles is most likely to become increasingly common, as insects seek out new habitats. A change in geographical distribution is just one way in which climate change has influenced, and will continue to influence, insects. A broad range of additional climate change induced effects, revealed through recent studies, will most likely impact upon the future survival and fitness of many species. High temperature reduces the time that is needed for insects to raise their body temperature to the f light activity threshold (Beaumont and Hughes, 2002). As an outcome of this, there may be an increase in activities that rely upon flight, such as mate location and egg laying (op.cit). As a result, many of the predicted impacts upon butterfly species have been positive. However, other aspects of climate change, such as drought, may have undesired effects. Prolonged arid conditions can have a negative impact upon host plant growth and egg survival (Roy and Sparks, 2000). One of the most recognized changes observed in butterflies is advancement in their first appearance (op.cit). This has been observed in most British butterfly species, showing a strong correlation with elevated temperatures. It has been predicted that per 1ËÅ ¡C temperature increase, the first appearance of butterflies could advance by 2-10 days (op.cit). Advances in appearance have also been demonstrated in other insect groups. One month advancement in the spring appearance of Heteroptera species was found in Japan, and was also a consequence of soaring temperatures (Musolin, 2007). Other responses noted in insects include behavioural responses in Heteroptera, though they havent been frequently discovered. In Italy, a large number of seed bugs entered urban buildings during the summer. Apparently, this was done in an attempt to escape the harsh high summer temperatures and to find more suitable conditions for aestivation (op.cit). The diversities of dragonfly, butterfly and grasshopper species are expected to decrease in Belgium, if the predicted climate scenarios for 2100 are correct (Maes, 2010). Mortality can be one of the direct consequences of temperature as insects have specie-specific upper and lower temperature limits. In peacock (Inachis io) and comma (Polygonia c-album) butterflies, the proportions of individuals reaching adulthood differed dramatically with varying temperature (Bryant et al, 1997). 60% survived at 15-30ËÅ ¡C, 0% at 9ËÅ ¡C and 20-40% at 34ËÅ ¡C ( op.cit). Whilst such implications of global climate change are worrying, there may be some potential benefits. Metabolic rate is expected to double with each 10ËÅ ¡C increase and mortality due to cold temperatures during the winter many reduce (Stange and Ayres, 2010). An increase in insect abundance is most probable and can be supported by recent outbreaks such as the gypsy moth (Lymantria dispar) in Central Europe (Cannon, 1998). The extent to which insects are susceptible to extinction will depend partly upon their geographical location. Those inhabiting the tropics are likely to be most at risk as they are highly sensitive to temperature and are already living fairly close to their upper thermal limits (Deutsch et al, 2008). Population growth rates in the tropics are predicted to decrease by up to 20%, further reducing fitness (op.cit). Biological traits which will cause species to have a greater extinction risk include reduced dispersal ability and low temperature toleranc e. (op.cit). Most species which possess such characteristics inhabit low latitude areas. Unfortunately, whilst tropical areas are the most vulnerable, they are also the parts of the world which harbour the greatest biodiversity. In comparison, those insects in mid-high latitude areas are expected to experience increased population growth rates (op.cit). At higher latitudes, organisms are living at temperatures that are cooler than their optimum temperatures, so global warming could potentially enhance their fitness (op.cit). It can be seen that much effort has been made in an attempt to understand the links between insects and global climate change, and research will continue to try and establish which species are of greatest conservation concern. However, a key consideration which will play a role in extinctions is the extent to which species will be able to adapt (Cannon, 1998). Unfortunately, this is tremendously complicated to predict and as a result, many studies often overlook , or some have even exaggerated potential evolutionary adaptations. During the quaternary period, large-scale fluctuations in climate occurred, but the insect fossil record provides no evidence for large-scale evolutionary change during this time (op.cit). Many studies have also focused heavily upon temperature effects and have poorly investigated how rainfall and moisture could impact insects. However, this is mainly due to lack of information, as making predictions about rainfall patterns is relatively difficult. It can be expected that climate change will increase the abundance and distribution of the majority of insects but it must be remembered that responses will be specie-specific and care must be taken to avoid over-generalising predicted responses. Effort must be made to enhance our understandings, whilst aiming to fill current gaps in knowledge. 4.0 Polar Bears The polar bear is often regarded as a marine mammal. Although this animal is quite efficient at exploiting marine habitats, it cannot survive within marine waters. Therefore this large predator can be more appropriately referred to as a terrestrial mammal as it lacks the specific adaptations possessed by true marine mammals such seals. Arctic sea-ice is critical to the survival of polar bears, as they depend upon it for numerous aspects of their ecology (Sterling and Derocher, 1993). It acts as a substrate on which to make long distance movements, provides access to maternal denning areas and is a platform for mating (op.cit). Most importantly, the ice allows polar bears to hunt and feed upon their primary prey; ringed seals (Pusa hispida) and bearded seals (Erignathus barbatus) (Regehr et al, 2010). Therefore, changes to sea-ice habitat are expected to have a dramatic impact upon the survival and reproduction of individuals, ultimately affecting the status of the polar bear as a spe cies. With global climate change well underway, changes to arctic ice have already been documented. Since 1978, 14% of the total amount of ice cover has already been lost (Derocher et al, 2004). Thinning of ice is occurring and sea ice is breaking earlier in the year and freezing later. It has been speculated that in as little as 100 years, the arctic ice cap may disappear completely (Sterling and Derocher, 1993). Numerous studies have demonstrated how changes in sea-ice, undoubtedly influenced by rising global temperatures, are causing polar bears to suffer as a result. Polar bears prefer to hunt on ice which lies over the continental shelf, as the waters here are more productive than arctic basin waters (Regeher et al, 2010). Therefore, longer ice free periods over this area could lead to reduced foraging success and in turn could impact survival and reproduction. Between 2001 and 2005, declines in polar bear survival were observed (op.cit). This observation was linked to longer i ce free periods over the continental shelf. It forced individuals to spend more time hunting on ice situated over less productive waters and caused some to seek alternative prey on land (Stirling and Parkinson, 2006). In western Hudson Bay, Canada, the sea-ice now melts completely each year, giving polar bears no other choice but to spend a proportion of the year ashore (Regehr et al, 2010). Individuals on land suffer food shortages. Ice free periods in 2004 and 2005 were associated with rare behaviour (op.cit). There were incidences of cannibalism and even starvation, indicating the severity of food unavailability (op.cit). In addition, living on land increases the exposure to humans, further enhancing their risk (Sterling and Derocher, 1993). Research concerning female polar bears has produced somewhat disturbing conclusions. Not only are the weights of females decreasing (figure 2), reducing cub survival and reproduction rates, but it is expected that within 100 years most female s in Western Hudson Bay will be unable to reach the minimum body mass required to rear viable offspring (Derocher et al, 2004). Figure 2 Mean estimated mass of lone (and thus possibly pregnant) adult female polar bears in Western Hudson Bay,1980-2004 (dashed line indicates fit of linear regression), (Sterling and Parkinson, 2006). Thinning of ice is also occurring due to climate change. Thinner ice moves more quickly which could mean that polar bears need to use more energy to stay in contact with their preferred habitats (Derocher et al, 2004). Ice of reduced thickness also breaks up more easily. It has been shown that polar bears completely abandon ice and move to land when the concentration of ice drops below 50% (Derocher et al, 2004). This is most probably due to the increased costs of locomotion which are associated with walking over fragmented ice (op.cit). Considering that ice is required for long-distance movements, changes in ice may influence the distribution of polar bears. Large areas of open water due to lack of ice in addition to strong currents, may function as barriers, preventing the movement of polar bears, as implicated in South-eastern Baffin Island and Eastern Beaufort Sea (Sterling and Derocher, 1993). Through the assessment of a variety of studies, it can be seen that the future for pol ar bears within the midst of climate change does not look hopeful. They are highly specialised mammals, are already listed as threatened under the US Endangered Species Act and their habitat is declining rapidly (Derocher, 2010). The population most at risk is that in Beaufort Sea, as it is experiencing severe nutritional stress. Drastic declines for this population are predicted and it may even vanish by the end of the century (Hunter, 2010). However, research has shown that there is still time to avoid such a scenario, providing effort is made to reduce greenhouse gas emissions. This indicates that the future of this species lies solely in the hands of policy makers, who have the supremacy to implement the nesseccary changes needed for not only the preservation of this species, but for many more too. 5.0 Birds Local variation in climate has long been recognised as an important factor affecting birds, but addressing how they will cope with long-term global climate change has only recently been attempted (Crick, 2004). Migratory birds have been of great interest, and this isnt surprising, considering that regular long-distance flights enable individuals to exploit various climates in different locations around the globe. Warmer winters are predicted to cause a slight increase in the number of short-distance migrant and resident bird species, whilst there will be a strong decline in the number of long-distance migrants (Lemoine and BoÃÅ'ˆhning-Gaese, 2003). This will likely be due to the increased competition resulting from resident bird species benefiting from the warmer conditions (op.cit). Migratory birds are also thought to be affected by mistiming, a result of climate change. This is when birds fail to breed at the time when their main food supply is most abundant (Both et al, 2006) . A study concerning the long-distance migratory pied flycatcher (Ficedula hypoleuca) showed that populations declined by 90% in 20 years as a consequence of this (op.cit). However, on a more positive note, it has been suggested that migratory birds are faced with a lower extinction risk that sedentary species, due to their high mobility (Sekercioglu et al, 2008). With the forecast of an intermediate climate change scenario (surface warming of 2.8ËÅ ¡C), it can be expected that 5% of sedentary species will become extinct, compared to 1% of long-distance migrants (op.cit). Global climate change appears to be causing birds to lay their eggs earlier. Data derived from the British Trust of Ornithology Nest Record Scheme revealed that 51 UK species showed trends towards earlier laying over a 25 year period (Crick, 2004). These trends were apparent throughout a variety of bird groupings including seed eaters, corvids and water birds (op.cit). The pied flycatcher exhibited an increase in egg and clutch size when eggs were laid earlier, indicating that warmer temperatures may be advantageous (op.cit). By the year 2080, it has been estimated that laying dates will be earlier for 75% of bird species (Crick and Sparks, 1999). This is a positive prediction as the advancement of laying dates suggests that birds are coping with temperature rises (Both et al, 2004). It may also mean that the incidence of mistiming may be reduced as the timing of hatching will be brought closer to that of peak food supply. In terms of distribution, elevational distribution shifts are probable. Pounds et al (1999) studied the mountain cloud forests of Costa Rica. It was shown that global warming had caused the average altitude at the base of the orographic cloud base to rise. This resulted in the colonization of previously cloud forest areas by birds from lower altitudes (Crick, 2004). There are concerns that such changes could have a detrimental impact upon some species. Through modellin g in the UK it has been suggested that species such as the snow bunting (Plectrophenax nivalis) may contract their range or even vanish from current breeding areas in the mountainous zones of the Grampians, Scotland (op.cit). Sekercioglu et al (2008) undertook a study to discover the impact of elevational limitations on the extinction risk of land birds (87% of all bird species). It was found that limitations in elevation actually accounted for 97% of the probability of a species being in a World Conservation Union category of extinction risk (op.cit). Using a model that combined elevational limitations and four habitat loss scenarios, it was predicted that 400-550 avian land species will be extinct and a further 2150 will be at risk, under an intermediate climate change scenario for 2100 (Figure 3 and Figure 4). Figure 3 The number of world landbird species estimated to be extinct by 2100, on the basis of different surface warming estimates, three possible shifts in lower elevational limit and four Millennium Assessment habitat change scenarios (Sekercioglu et al, 2008). Figure 4 The number of world landbird species estimated to be at risk of extinction (near threatened or threatened) by 2100, on the basis of different surface warming estimates, three possible shifts in lower elevational limit and four Millennium Assessment habitat change scenarios (Sekercioglu et al, 2008). 6.0 Conclusion Although most responses to global climate change are expected to be specie-specific, potential distributional changes appear to be quite uniform. Northern distribution shifts are likely to become increasingly common as species seek cooler climates. Elevational distributional changes will also occur, though elevational limitations in birds may increase their extinction risk. Impacts may range from phenological changes such as earlier breeding, to mortality resulting from temperatures exceeding thermal limits. Insects could potentia
