T. C. Boyles When the killings done - Essay Example Pinpoint five or six instances where environmental issues, including problems, become apparent. Perhaps the most spectacular feature of T. C. Boyle’s striking novel titled When the killing’s done is that on many accounts it escapes the stagnation that one might connect with a novel of its genre – the narrative is not only regarding animal rights as it may appear at first but in his story, Boyle showcases the dynamism and complexity that is associated with environmental activism, morality, ethics and the family life which shapes the actions and intentions of a human being. The purpose of this essay is to highlight the background for Boyle’s story by bringing to light the underlying environmental issues in the novel, in doing so the paper draws attention to five instances that are present in the book where problems and issues related to the environment become evident. In conclusion the essay examines the impact of Boyle’s novel in creating awareness r egarding aspects related to environmental activism such as biodiversity management, the issue of non-native species in habitats and the redesigning of ecosystems. At the crux of the narrative that is presented in When the killing’s done lies the conflict between Alma Boyd Takesue and Dave Lajoy. While, Alma seeks the absolute eradication of invasive species such as black rats and feral pigs on the islands of Santa Cruz and Anacapa, for Lajoy the killing of an animal regardless of its categorization as an invasive species is a grave violation of morality and â€Å"†¦that’s what he has to remember: save the animals† (Boyle p75). The varying perceptions and motivations of the two characters in advancing their environmental agendas is not only reflective of a conflict or problem that seeks resolution within the novel itself but also gives insight into the dilemmas associated with environmental activism in the real world. The fundamental question here is that wh en the benefits of environmental activism and protecting the flora and fauna are agreed upon on a widespread scale, why is it that human beings cannot collaborate in harmony to achieve a common objective? Due to its focus and analysis of the subjectivity associated with morals and ethics in environmental activism on a macro level, Boyle’s novel intends to spread a message that comprehends the need to strike a balance between values, morals and ethics for the overall good of humanity. Another aspect that is prominent in the novel has been crafted by Boyle in the background stories of the characters, in fact, it would be correct to state that Alma owes her existence to the island – the island saved Alma’s grandmother from possible death which could have been the consequence of a shipwreck that occurred in 1946. Furthermore, Lajoy’s girlfriend Anise Reed also shares a special relationship with the islands due to her mother’s employment at a ranch loca ted on the island. The implications of these relationships that have been woven within the narrative by Boyle necessarily enhance the dramatic element of the novel to portray the characters and their situations in a manner that is believable. Alma’s determination to promote her cause and garner the attention of the press on the issue of environmental concern also stems from personal reasons, which enhances the ambiguity of the criterion for right and wrong, thereby, enhancing the subjectivity that is associated with an individual’s motivation for environmental activism and selecting the best possible method of conservation. In essence, When the killing’s done documents decades of changes in habitats, ecosystems and the environment that have been brought about by the

Alcoholic Beverage Essay Example for Free

Alcoholic Beverage Essay An alcoholic beverage is a drink containing chemicals from the alcohol family. Mostly ethyl alcohol (ethanol, EtOH), other alcohols are usually present only in small quantities, notably consumable t-Amyl alcohol (t-Amylol, t-AmOH) which is about 20X more potent than ethanol, and hazardous methanol with much weaker sedative effect than ethanol, thus are not prohibited by law or regulated by taxation in most if not all countries. However, alcoholic beverages are divided into three general classes for taxation and regulation of production: beers, wines, and spirits (or distilled beverage). They are legally consumed in most countries, and over 100 countries have laws regulating their production, sale, and consumption.[2] In particular, such laws specify the minimum age at which a person may legally buy or drink them. This minimum age varies between 16 and 25 years, depending upon the country and the type of drink. Most nations set it at 18 years of age.[2] In the human body, ethanol affects the gamma-aminobutyric acid (GABA) receptors and produces a depressant (neurochemical inhibitory) effect. Ethanol is similar to other sedative-hypnotics such as barbiturates and benzodiazepines both in its effect on the GABAA receptor, although its pharmacological profile is not identical. It has anxiolytic, anticonvulsant, hypnotic, and sedative actions similar to many other sedative-hypnotic drugs. Ethanol is also cross-tolerant with benzodiazepines and barbiturates.[3] In fact, a synthetic alcohol based on benzodiazepines is currently developed by a team at Imperial College London, led by Professor David Nutt (chair of ISCD). The alcohol substitute give the drinker the effects of drunkenness without many of the risks of alcohol;[4] Accordingly to ISCD alcohol was the most harmful of all drugs considered, scoring 72%. Alcohol is the most available and widely abused substance and its chronic consumption causes neurobehavioral disorders.[5] A high-functioning alcoholic (HFA) is a form of alcoholism where the alcoholic is able to maintain their outside life such as jobs, academics, relationships, etc. – all while drinking alcoholically.[6] Under the DSMs new definition of Alcoholism about 37 percent of college students may meet the criteria. Doctors are hoping that this new definition of the term will help catch severe cases of alcoholism early, instead of when the problem is full-blown.[7] Alcoholism is a neurodegenerative disease which may lead to physical dependency that can be fatal in alcohol withdrawal syndrome due to its propensity to induce withdrawal convulsions. The production and consumption of alcohol occurs in most cultures of the world, from hunter-gatherer peoples to nation-states.[8][9] Alcoholic beverages are often an important part of social events in these cultures.

City-States in Lower Mesopotamia :: Ancient Egypt Egyptian History

City-states in Lower Mesopotamia Factors that contributed to the emergence of city-states in Lower Mesopotamia and the influence the landscape played in the formation of the civilization which emerged. For this essay I considered the question of what factors contributed to the emergence of city-states in Lower Mesopotamia and the influence the landscape played in the formation of the civilization which emerged. Through my research on this topic I found that there is much evidence to support the claim that landscape was a very large influence on the emergence of civilization and that most of the contributing factors were, in some way, linked to geography. In order to fully understand the topic, I first explored what the definition of civilization is. The first criterion for civilization, that I could think of, is domestication and an agricultural economy capable of producing a stored surplus. From this, I felt the need to examine the origins of Mesopotamian agriculture. With the glacial retreat after the last ice-age (roughly 10000 BC) the Mesopotamian climate improved and many modern plants and animals began to become concentrated in specific areas. Around 9000 BC the vast majority of Mesopotamian peoples were hunter-gatherers. With the concentrations of plants and animals being in specific areas these hunter-gatherers soon began to domesticate those plants and animals and a sedentary village farming pattern arose. This became the predominant way of life around 6000 BC. This change from food collecting to food producing was one of the major transformations in human history. Early peoples no longer had to live the nomadic life of hunter-gatherers but could settle down in permanent housing and produce their own food. It also began an economic change that altered social and political institutions, religion, etc. Domestication is the process of altering plants and animals so that they are no longer bound to the natural habitats of their wild ancestors. In essence they become more productive and useful to people. This process sometimes even includes changes in the genetics of the domesticated plant or animal. In Mesopotamia the major domesticated species of plants were wheat, barley, chickpeas, peas, grapes, olives, walnuts, almonds, pistachios, apricots, dates, and figs. The major domesticated species of animals were cattle, sheep, goats, and pigs. Some of the genetic changes brought about through domestication and the careful breeding of plants and animals include plants that were bred to have more and bigger useful parts and animals that were initially bred to be smaller and less aggressive, and only later to have more of their useful parts.

A Bergerian Reading and Chris “Ludacris” Bridges

The whole of our existence is shaped by our experiences – the various situations that we find ourselves in. Parts of our experiences are influenced by what we see, and what we see takes us to new levels of experiences that allow us to situate ourselves in thoughts or visions represented by what we virtually perceive.Interpretations of visual texts, such as works of art, therefore are based on our perceptions and points of view, consequently leading to subjectivity despite the conventional meanings embedded within these works of art by the artist.Under these pretexts, various works of art, borne out of the social events, situations, or landscapes in the past, become subjects of mystification. Such are the views or perspectives of John Berger on art, particularly on Franz Hals’ portraits, the â€Å"Regents of the Old Men’s Alms House† and the â€Å"Regentesses of the Old Men’s House† (1580-1666) – that the social construct from which the se works were created are mystified because of its incongruity to modern times.Berger, a seasoned art critique, presented a complex yet analytical perspective on the works of Hals, focusing on their being representative of history and how they are inevitably mystified not only by our perspectives as inhabitants of the modern day world but also Hals’, in his own words, oversimplification of what the portraits truly imply.Moreover, because of Berger’s analysis and personal critiques on the work of Hals, we as viewers of the visual text, begin to understand that the portraits are not merely images that represent superficial artistic and social elements such as unity and harmony, the ideas formed from observing facial expressions, gestures, and such.Furthermore, Hals’ works of art are snapshots of the social and economic situations that the artist, the regents and the regentesses found themselves in.The portraits seem to capture the kind of relationship that exists between the artist and the subjects of art, expressing something more – a drama that represents a historical landscape that is shared by Hals and his subjects within a social environment that was illuminated and solidified by large gaps among social groups or classes – brought to life by Hals’ artistry and ingà ©nue in translating emotions and perspectives to visual arts.The analytical perspectives of Berger as explored in his interpretations of Hals’ portraits shall be utilized to describe the messages or arguments evident in a portrait taken of the actor/rapper Chris â€Å"Ludacris† Bridges. In order to do so, it is highly significant to go over Berger’s perceptions or points of view on viewing art, particularly of Hals’ portraits, by creating a framework from which the visual analysis of the Ludacris’ portrait shall be based on.According to Berger, the act of viewing pieces of art may be done in various ways depending on: a ) one’s perspective, b) the artists’ perspective, c) other people’s perspectives, d) the social, economic, or political situations within which the piece of art was conceptualized, and e) the present social, economic, or political situations completing a shared link between the past and the present.Moreover, Berger stressed that it is equally important that in order to understand the genuine sense or value of pieces of art, that viewers look or interpret them beyond their personal perspectives and the pictorial nature of the portrait.Viewing art should not adhere to convention of perspectives that was existent during the Renaissance because it limits the span of pieces of art to convey deeper and comprehensive meanings. The convention of perspectives isolates what the viewer might all-inclusively learn cognitively, emotionally or psychologically, socially, spiritually and such.Therefore, reading or interpreting visual texts should be a combination of one’ s perspectives as they relate to the artists’ and other people’s perspectives, and the connections between the social, economic, and political situations from past to present. Human beings should also be aware that they are represented by and connected to art, as art is also able to view the viewer because of shared visual perspectives.The key to analyzing Ludacris’ portrait is to view it radically, if we are to align ourselves with Berger’s ideologies and perspectives. Ludacris’ portrait, being an image intended to represent remarkable style to signify celebrity-like success, borders on deception and absurdity.The explicit message that the artist photographer Robert Maxwell intended to express was associated with the vision of Moà «t & Chandon; and that is, how adapting elegant, stylish, and distinctive fashion may be translated to remarkableness and success in the limelight that are consequently significant causes for celebration This argument i s solidified by the nature of the camera – a narrow and limited perspective of things and situations – utilized by Maxwell in order to represent a specific idea or though restricted by the visualizations or representations of Moà «t & Chandon, an well-known international producer of champagne that embodies conceptions of â€Å"splendour, pleasure, and prestige.† (Moà «t & Chandon)

Dry Ice Composition and Uses

Dry Ice Composition and Uses Dry ice is the general term for solid carbon dioxide (CO), coined in 1925 by Long Island-based Prest Air Devices. Though originally a trademarked term, dry ice has become the most common way of referring to carbon dioxide in its solid, or frozen, state. How Is Dry Ice Manufactured? Carbon dioxide is frozen by compressing carbon dioxide gas to a high pressure to create dry ice. When it is released, as liquid carbon dioxide, it quickly expands and evaporates, cooling some of the carbon dioxide down to the freezing point (-109.3 F or -78.5 C) so that it becomes solid snow. This solid can be compressed together into blocks, pellets, and other forms. Such dry ice snow also forms on the nozzle of a carbon dioxide fire extinguisher when it is used. Special Properties of Dry Ice Under normal atmospheric pressure, dry ice undergoes the process of sublimation, transitioning directly from solid to gaseous form. In general, at room temperature and normal pressure, it sublimates at a rate of 5 to 10 pounds every 24 hours. Because of the very low temperature of dry ice, it is used for refrigeration. Packing frozen food in dry ice allows it to remain frozen without the mess that would be involved with other cooling methods, such as water from melted ice. Several Uses of Dry Ice Cooling materials- food, biological samples, perishable items, computer components, etc.Dry ice fog (see below)Cloud seeding to increase precipitation from existing clouds or decreasing cloud thicknessTiny pellets can be shot at surfaces to clean them, similar to sanding ... since it sublimates, the benefit is less residue to clean upVarious other industrial uses Dry Ice Fog One of the most popular uses of dry ice is in special effects, to create fog and smoke. When combined with water, it sublimates into a cold mixture of carbon dioxide and humid air, which causes condensation of water vapor in the air, forming fog. Warm water speeds up the process of sublimation, producing more dramatic fog effects. Such devices can be used to make a smoke machine, although simplified versions of this could be created by putting dry ice in water and using fans on low settings. Safety Instructions Do not taste, eat or swallow! Dry ice is very cold and can damage your body.Wear heavy, insulated gloves. Since dry ice is cold, it can damage even your skin, giving you frostbite.Do not store in sealed container. Because dry ice constantly sublimates into carbon dioxide gas, storing it in a sealed container will cause pressure to build up. If it builds up enough, the container could explode.Use only in ventilated space. In a poorly ventilated area, the build up of carbon dioxide could create a suffocation hazard. This is a great danger when transporting the dry ice in a vehicle.Carbon dioxide is heavier than air. It will sink to the floor. Keep this in mind when thinking about how to make the space ventilated. Obtaining Dry Ice You can buy dry ice at most grocery stores. You have to ask for it, though. Sometimes there might be an age requirement on buying dry ice, requiring someone age 18 or over. Edited by Anne Marie Helmenstine, Ph.D.

Validez en EE.UU. de matrimonio celebrado en otro país

Validez en EE.UU. de matrimonio celebrado en otro paà ­s Estados Unidos reconoce como vlidos los matrimonios celebrados en otros paà ­ses siempre y cuando cumplan todos los requisitos exigidos por la ley que aplica en el lugar de la boda. Esto aplica tanto a matrimonios entre una mujer y un varà ³n como a la unià ³n entre dos personas del mismo sexo. Como consecuencia de este reconocimiento de la validez del matrimonio celebrado fuera de EE.UU. se derivan dos efectos. En primer lugar, si una persona que se casà ³ en otro paà ­s desea contraer un nuevo matrimonio deber ser viuda, anular su divorcio o proceder a divorciarse, lo cual puede hacer aà ºn cuando no tenga nacionalidad estadounidense y matrimonio se hubiera celebrado en otro paà ­s. En segundo lugar, por matrimonio como ciudadano estadounidense o residente permanente legal es posible emigrar a los Estados Unidos sacando una tarjeta de residencia conocida como green card si cumple con todos los requisitos que exige la ley migratoria. Puntos clave: validez en EE.UU. de matrimonio celebrado en otro paà ­s Si el matrimonio es vlido segà ºn la ley del paà ­s en el que se celebra, es vlido en EE.UU.Los oficiales consulares de EE.UU. no celebran matrimonios.El matrimonio con ciudadano o residente, por sà ­ mismo, no da derecho a emigrar a EE.UU.Para emigrar a EE.UU. por matrimonio, el ciudadano o residente debe pedir a su cà ³nyuge Respeto por las leyes locales que regulan el matrimonio Para que Inmigracià ³n de Estados Unidos reconozca como vlido a un matrimonio celebrado en el extranjero, à ©ste debe ajustarse a la ley local del lugar en el que la pareja se casà ³. Hay que tener en cuenta que en algunos paà ­ses se exige a los dos novios tener la residencia allà ­ para poder casarse. Adems, si uno de los contrayentes es menor de edad se va a pedir algà ºn tipo de autorizacià ³n de los padres o tutores. Incluso en algunos paà ­ses se exigen determinados anlisis de sangre, requisito que hay que cumplir si es que asà ­ se pide legalmente. Ya que para que EE.UU. reconozca como matrimonio vlido que cumpla con las leyes locales, en el caso de parejas gays es imprescindible celebrar la boda en un estado o en un paà ­s donde es legal. Si no se hace asà ­, no tendr efectos migratorios. En otras palabras, el ciudadano o residente no podr pedir los papeles para su cà ³nyuge, porque EE.UU. considera que no estn casados legalmente. Problemas del matrimonio por poderes para Inmigracià ³n Si la intencià ³n es pedir la tarjeta de residencia permanente para el cà ³nyuge extranjero, se recomienda no casarse por poderes. Las leyes migratorias de EE.UU. exigen que el matrimonio se consume antes de aprobar cualquier peticià ³n por esta causa. Los matrimonios por poderes pueden crear la sospecha de que matrimonio no se ha consumado o que se trata de un matrimonio de conveniencia para sacar los papeles. Documentos  para casarse fuera de EE.UU. El ciudadano estadounidense que se casa en el extranjero deber probar quià ©n es mediante  una identificacià ³n con foto, generalmente el pasaporte americano vigente. Adems es normal que se pida documentacià ³n adicional, como copia de la partida o certificado de nacimiento. Si el contrayente ha estado casado previamente  deber presentar la sentencia del divorcio o la nulidad o el certificado de viudedad. Hay que tener en cuenta que posiblemente se pida que estos documentos sean traducidos al idioma del paà ­s en el que tendr lugar la ceremonia. Por otra parte una vez celebrado el matrimonio fuera de los Estados Unidos ser necesario traducir al inglà ©s el certificado de matrimonio para su uso migratorio. La  traduccià ³n puede hacerla cualquier persona con un conocimiento fluido del inglà ©s y del otro idioma y se necesita certificar la traduccià ³n, lo cual puede hacerse siguiendo un modelo de carta. Autentificacià ³n de documentos de matrimonios celebrados en el extranjero Dependiendo del uso que se quiera dar dentro de Estados Unidos al certificado de matrimonio de celebrado en otro paà ­s es posible que se necesite una autentificacià ³n, que puede ser de dos tipos. En primer lugar, un sello que se conoce como  apostilla de la Haya. La mayorà ­a de los paà ­ses de habla hispana forman parte del Convenio de la Haya y ese sello es el que se necesita para legalizar el certificado de matrimonio que se desea utilizar en Estados Unidos. En segundo lugar, para los paà ­ses que no forman parte de este convenio ser necesario obtener una certificacià ³n de legalidad. Cabe destacar que, para trmites con el Servicio de Inmigracià ³n y Ciudadanà ­a (USCIS, por sus siglas en inglà ©s), por regla general es suficiente una traduccià ³n certificada y no se exige la apostilla de la Haya.  ¿Bodas en embajadas y consulados  de EE.UU.? Ni los cà ³nsules ni ningà ºn oficial de las oficinas diplomticas de los Estados Unidos est autorizado para celebrar bodas en el extranjero. Por ello, sà ³lo en casos muy excepcionales es posible que un matrimonio tenga lugar en el edificio de una embajada o un consulado. Sin embargo, en algunos casos los consulados sà ­ que prestan un servicio necesario cuando algunos paà ­ses se exige por parte del contrayente extranjero una declaracià ³n jurada de que tiene la capacidad legal para contraer matrimonio. Este tipo de declaraciones se pueden prestar ante un oficial consular americano que tienen poder para actuar como notarios pà ºblicos en el extranjero. Traer al cà ³nyuge extranjero a vivir a Estados Unidos El matrimonio con un ciudadano americano o residente, por sà ­ solo, no da derecho a viajar a Estados Unidos ni a permanecer en el paà ­s para a vivir y trabajar. Si la intencià ³n del nuevo matrimonio es vivir en EE.UU, el cà ³nyuge estadounidense o el residente permanente debe pedir una tarjeta de residencia por matrimonio para su esposo o mujer y tambià ©n para los hijastros, si se cumplen condiciones estrictas de edad. Adems, los ciudadanos estadounidenses –pero no los residentes– tienen la opcià ³n de solicitar una visa K-3  para su cà ³nyuge y una K-4 hijos o hijastros en vez de seguir el proceso ordinario de peticià ³n de cà ³nyuge. En realidad estas son unas visas muy poco utilizadas y solo son convenientes cuando los plazos de tramitacià ³n de la peticià ³n ordinaria de la green card para cà ³nyuge de ciudadano son muy largos. En estos casos siempre es mejor estar aconsejado por un abogado migratorio. En los casos de cà ³nyuge extranjero fuera de EE.UU. y ciudadano o residente en los EE.UU. existe la tentacià ³n de que en vez de iniciar un proceso de peticià ³n de la green card el cà ³nyuge extranjero ingrese como turista a los Estados Unidos y luego solicitar un ajuste de estatus para obtener la green card. Esa opcià ³n no es la correcta desde el punto de vista migratorio y puede dar lugar a que no se le permita el ingreso al paà ­s y se le expulse en el puesto de control migratorio o, si consigue ingresar, no se le apruebe la peticià ³n de green card. Esto es asà ­ porque se puede considerar que ingresà ³ al paà ­s en fraude de ley al utilizar un estatus de turista cuando su intencià ³n era ingresar a EE.UU. para quedarse. En estos casos la intencià ³n es fundamental y es recomendable aconsejarse con un abogado para evitar problemas con el USCIS cuando se presente la solicitud de la green card. Finalmente, cabe destacar que en los casos en los que el  ciudadano  que desea traer a vivir a Estados Unidos a su esposo extranjero puede tener problemas muy particulares si el estadounidense siempre o en los à ºltimos aà ±os ha residido fuera de los Estados Unidos. El problema es que podrà ­a ser difà ­cil probar medios econà ³micos suficientes para patrocinar, tal y como lo pide la ley. Adems, para pedir los papeles se exige que el patrocinador resida o tenga como residencia principal los EE.UU. Condicionalidad de la green card En muchos casos, la green card que se obtiene por matrimonio con un ciudadano es condicional por dos aà ±os. Es lo que se conoce como CR-1. En estos casos se exige activamente levantar la condicionalidad.  Esto ocurre cuando la residencia se otorga antes de que la pareja lleve dos aà ±os de casados. Por el contrario, si el cà ³nyuge extranjero de un ciudadano obtiene su tarjeta de residencia despuà ©s de haber cumplido el segundo aniversario de casado su visa de inmigrante es una IR-1 y es definitiva, es decir, no necesita levantar ninguna condicionalidad. Matrimonios de conveniencia Las autoridades migratorias son conscientes de que a veces los matrimonios son una farsa y su à ºnico objetivo es obtener la green card. Cuando se llega a esa conclusià ³n puede haber consecuencias serias. Adems, durante la tramitacià ³n de los papeles puede suceder que se lleven a cabo investigaciones para intentar determinar si el matrimonio es real y siempre existe el riesgo de una denuncia anà ³nima sobre la finalidad del matrimonio. Test de respuestas mà ºltiples Para entender la green card, cà ³mo obtenerla, obligaciones, derechos, cà ³mo conservarla y cà ³mo es posible perderla por cancelacià ³n es importante tener los conocimientos bsicos.   Este test de respuestas mà ºltiples es muy aconsejable ya que el conocimiento evita meterse en problemas de los que luego es difà ­cil salir.

buy custom Case Analysis-Terri Schiavo essay

buy custom Case Analysis-Terri Schiavo essay Terri Schiavo was a legal case in the United States of America that involved the parents of Teresa Marie Schiavo and her legal guardians. Teresa Schiavo was commonly referred to as Terri. Terri was the main subject of this legal case. In 1990, she collapsed at her home in St. Petersburg, Florida due to cardiac arrest. Her brain was damaged due to ineffective supply of oxygen, and she remained in a coma for two months. Her condition was elevated to vegetative state. Doctors tried to restore Terry to the state of awareness through physical and experimental therapy. In 1998, her husband felt that her feeding tube be eliminated, and he filed an appeal in line with the Florida Statutes contained in section 765.401. Terris parents who claimed that she was in her conscious state objected this. The issue reached the level where the only solution could be found from the court. The court held that Terri did not wish to continue with the life prolonging measures. Her feeding tube was thus remov ed, but it was later reinserted after the court gave an injunction to stop the removal of the feeding tube. In 2005, a court in Penillas County ordered that her feeding tube is removed. This led to numerous appeals in courts concerning the issue. The most significant appeal was the one signed by the then US president George W. Bush, to keep her alive. The appeals in the federal courts come and passed, but the origin decision of removing her feeding tube was up held. The tube was removed on 18 March 2005, and; unfortunately, she passed on just a few days prior to the removal. An individual is obliged to turn down medical care if one feels he is all right. For instance, the court asserted that Terri did not wish to continue with the life pro-longing measures. This meant she did not wish to continue with the medical care in the long- run. This was her right and no one could object to it. Her wish against medical care was to be adequately addressed because there was a feeling that she was self supportive. The case brings out both moral and ethical issues. The moral issue drawn from the case is greed. It is perceived that Terris husband takes the decision to have the feeding tube disconnected just because of his greed to posses Terris estates after her demise. Greed is the worst part of life that makes individuals decide anythng malicious against others. For instance, Terris husband was aware that the removal of the tune could result in the ultimate death of his wife, but he did not care. This was against her parents wishes. The husband was also aware that Terri was going to die intestate. This meant he could be the ultimate owner of the vast estates left behind. In this case, I would prefer that Terri be cared for in the life prolonging medical care to keep her for a longer time. This is just the human position to take because each one of us has a right to live until the right time for death comes. In addition, no one is supposed to terminate the life of another individual due to the greed of acquiring the remaining estates and property. The theory of human life and how best to live would be vital in explaining this ethical issue. All humans have a right to life and their lives are valuable. Life should thus be treated as a vital gift to humans that cannot be compared to matters such as property. Human beings must keep in mind that all other individuals have a right to existence and achievement of their dreams whichever even if their condition is unpredictable. Terri would ultimately die. This is because the tube that supports her life would be eliminated thus exposing her to death. She would not be able to survive any longer, as there are no support systems for her feeding mechanisms. Her husband would enrich himself. This is because it is in his best of interest that Terry dies and leaves behind the estates. He would thus gain from the death of Terri due to his greedy behavior. The doctors would be defeated to make a choice between supporting life or killing. The doctors duty is to facilitate the healing of an individual and not to kill. The elimination of the tube would be a way of killing Terri; this would leave them in a dilemma regarding what to do. The taxpayers would have to have to pay more to support the life of Terri if the tube is not eliminated. The parents would end up losing their beloved daughter due to the elimination of the tube. Terris parents would have supported my ethical position to have Terri continue living because she is their daughter and they still cherish her. On the other hand, her husband would be against this because he needs Terris estates after her demise. The health pollicy consideration in this case is that an individual is attended to according to his wish. The law asserts that an individual can choose the kind of attention he needs. If one feels that his condition is too critical and could not survive any longer, he has a right to call off medical care for self-support. In addition, the health policy provides that an individual would be cared for according to his wish. For instance, Terris husband claims that she did not wish to continue with the prolonged medical care and her wishes were ultimately addressed. The health issues relating to individuals are vital and should be treated with the utmost care. Tong (2000) asserts that matters relating to the lives of other people should be put into consideration before making any decision relating to their further treatment. Due care should be the guiding principle to ensure that all other individuals have a right to life. Human beings should not give up even if they are in a critical state that is perceived so complicated. For instance, everyone should have supported the issue that Terri stays with the tube for a longer period in order to ensure she continues living. The ethical issue arising from the case could have been avoided. For instance, if a will had been earlier drafted the husband could not have pushed for the removal of the tube. He would have known his position in the will in advance and thus the greed to own Terris estates would be eliminated. These issues would not have arisen. In addition, it could be avoided by mutual agreement on the course of action needed. If the parents and the husband had talked about the issue, there could be no conflict of interest.

Formal Memo Proposal - Research Paper Example Organizations have rivals as well as companies that complement their services. The audience should realize that the greater benefit goes to the end users who use the goods or services provided by the business. Traditional B2B transaction procedures are ineffective because they require enterprises to calculate transactions costs for setting up and maintaining stores. The personnel carrying out the transaction must be paid duly besides footing other business expenditure when linking up with other firms. Additionally, organizations must ensure that they have conducted many operations to decrease the overall costs incurred. The distributors are also required to prepare to handle high quantities of goods. Poor business-to-business transaction strategies have led to poor profits in businesses. Ineffective B2B strategies play a significant role in contributing towards massive losses that businesses incur when carrying out transactions. Dependence on stores to allow easy distribution of goods calls for extra business expenditures such as personnel to move and distribute goods to other enterprises. The current B2B transaction procedures are ineffective because of the high quantities of goods supplied. The transactions are run with utter inaccuracy due to involvement of high human processing systems.

Organisational Behaviours and HRM Coursework Example | Topics and Well Written Essays - 500 words

Organisational Behaviours and HRM - Coursework Example rce management and staff management may differ in so many ways depending on the scope, nature of the roles and even the services with human resource management being broader in perspective in both compared to staff management that is narrower in perspective. They too have similarities. The similarities can be summarized in terms of; Payroll & Associated Tasks, new staff recruitment procedures, the documentation processes, and models. In terms of models, both focus on the significance of integrating personnel and human resource management techniques with organizational objectives (Armstrong, 2006) so that both can aim to achieve a common overall objective. The organizational behavior concept and human processes are quite basic in relationship. Organizational behavior concept manifest themselves as some regulations or guidelines that define how employees in a given organization should conduct themselves when they want to engage themselves within certain activities like politics, examples include; organization culture, politics, and ethics. Human resource management, on the other hand, is concerned with implementing the said concepts by doing whatever is necessary to develop strategies of setting rules for the concerned employees. Example, under the organization concept of organization culture, human resource will be concerned with acting as an amplifier of the organization culture using any communication means like employee orientation to help him/her understand the said culture. The same is true for other concepts. The primary responsibility of a human resource manager is to ensure that human resources are utilized and managed as efficiently and effectively as possible (Saiyadain, 1999).

Traveling Through the Dark Essay Example for Free

Traveling Through the Dark Essay When reading a poem for the first time, it is fairly easy to view it on a literal level. Nonetheless, after analyzing the purpose, tone, word choice, and figures of speech and how they simultaneously work together, the reader is hit with a whole new perception of the poem. William Staffords Traveling through the Dark holds this characteristic. The poem is about a man driving on a narrow road at night and his internal conflict triggered by an encounter with a dead deer along the road. He immediately leaves his car and walks toward the deer with the intention of rolling it into the canyon. However, when he discovers that this deer has an unborn fawn, the man is struck with an instant conflict. Does he push the deer off into the canyon? Or does he leave it alone and save the fawn while endangering the lives of others that will travel this narrow road? Stafford uses a mans simple confrontation with a deer as an instrument for conveying a deeper message about nature. He comes across a dead deer, and without hesitation, plans to push it into the canyon. This clearly indicates that the speaker holds no emotions whatsoever for the deer. Then, a conversational tone is thrown into the mix. The narrator is sharing and guiding the readers through his experience. He gives advice in line four, It is usually best to roll them into the canyon. This supports his informal attitude and establishes a relationship with the reader in hopes of allowing the reader to feel the way he does. Several symbolic elements emphasize the theme of Traveling through the Dark, all within the last three stanzas of the poem. The first symbol, an unborn fawn. The fawn represents the future of nature in the changing world. Although the mother, or nature in present time, has been killed the fawn still waits alive, still, never to be born (11). The fawn waits in hope that it will live to breathe air, in the hope that the speaker will save it. However, technology is also competing for the speaker’s attention. The first three lines of the fourth stanza make the idling car into a mechanized beast that kills nature. Some details about this mechanized beast are on lines thirteen to fifteen where the car aimed ahead (13) its lights, purred (14) its steady, idling engine, and emitting warm exhaust turning red (15). The third and final symbol is revealed only in the last stanza. On line seventeen, I thought hard for us all exhibits the fact that the speaker is representative of all mankind. The speaker represents mankind coming around the curve in the dark. He symbolizes mankind being caught in the struggle between nature and technology. Nature in the form of a dead doe is portrayed as an object worthy of pity while the mechanical beast is a ruthless image. Among the various descriptions relating to the dead doe, the most conspicuous is of her being large in the belly (8). The heap, a doe (6) describes the speaker’s first impression of the recent killing. Aside from those two images, the other description of the doe correlates to the sense of touch; the speaker notices that that the doe’s side was warm (10) after brushing finger against her fur. Stafford describes the car with regards to three of the body’s five senses. The car is described as having its lights lowered (13) or dimmed, casting the scene in shadows. The steady purring emitted from the engine appeals to the speaker’s sense of hearing. Warm exhaust (16) caresses the speaker, stimulating the speaker’s sense of touch.

Communicating With People On The Internet

Communicating With People On The Internet The arrival of the internet has heralded a lot of new opportunities, created new markets, and afforded us new ways of interacting with each other. Meeting new people is no longer limited to talking to the person youre sitting beside on the bus, or keeping in touch with someone you met at a bar. Now we can find friends from continents away. The internet is a busy place, full of people, many of whom share your own passions and interests. And not just friends, its also a place where its possible to meet someone special. Naturally the hyper-connected youths of today use the internet as if its an extension of themselves. For them meeting new people online seems like a given. But the internet holds just as much promise for the rest of us. It has grown in popularity as a way to find friends, to chat among like minded people, and for finding love, sex, quick flings, soulmates, partners, husbands and wives depending on whos looking. Nowadays there are more and more people who are single enough to use it. The number of people getting divorced is higher than ever. The US, UK, Canada, Russia, New Zeland and Australia all in the top ten for highest divorce rates (per 1,000 people). Society has changed, and with it our values. It is no longer seen as socially unacceptable to leave someone. Why stay in an unhappy marriage? There are many women and men who have faced that very question. Of course there are still those who see it as a sign of a sinful society, or feminism run rampant, or the natural progression of a morally bankrupt western culture, or any number of fantasies that explain a trend in statistics they dont understand. In the past divorces were rare, but were the couples happy? Thankfully society is breaking free of old fashioned attitudes. Where it would have been seen as debauched and morally sinful for a woman to leave her husband, or a man to leave his wife, now individuals have an out. The modern world is about individual choice and personal freedom. Because of this, more people are single, and open to the possibility of meeting someone new. People are also working harder. A busy career can leave little time to build a social life and result in a stagnant love life. Success can often bring more work, and more money, at the expense of someone to share it with. Many successful individuals are even reticent when it comes to looking for love. Relationships can be a lot of trouble, and some people are content without them. Being far removed from our primitive origins, we are no longer slaves to biological imperatives. On the other end of the scale, its thought that as many as a third of the singles on the internet arent quite as single as youd think. But assuming we are single, free, and would like to find someone special, where do we look in the 21st century? Bars and clubs are naturally as popular as ever. Many people still meet through work and friends. Many people bump into that special someone through a random encounter a dropped batch of paperwork, getting stuck in a lift it could be clichà ©, but it will still happen for some of us. With the advent of the internet, meeting people online has become yet another option. A natural one, in this connected world we live in. Personals and dating are big business, bringing in $503.4 million (US) in 2005 and showing consistent year after year growth. And in the UK, with its population of around 60 million, 7.8 million singles used some form of dating service in 2007 according to a press release by dating service PARSIHP. Meeting people on the internet doesnt have to be conducted through dating sites either. Many people who use the internet find people naturally as they wander the landscape of cyberspace. Nor is this a new phenomenon. The dawn of the internet saw the creation of crude bulletin boards and internet relay chat. People found each other using these services just as they do using Messenger clients and forums today. The technology has definitely advanced through, and this has brought people a large number of places to go on the internet. There are many different services that run on the internet, here are some of them: Internet relay chat One of the oldest services on the internet, internet relay chat (IRC) is a service that posts messages to the page instantaneously so that the users can have a conversation that flows naturally in real time. There are thousands upon thousands of chatrooms available through IRC servers, and most of them are free. They can be accessed by downloading an IRC client, though sometimes a bit of configuring is needed to make it work. IRC isnt the easiest thing in the world to pick up and learn, a throwback from its early origins. Messenger clients From Yahoo Messenger to MSN, and now more recently Skype (which can be used in much the same way as a messenger between calls), messenger clients allowed people to manage a list of contacts and then chat with those contacts just like in IRC. Unlike IRC, big improvements were made to the interfaces and ease-of-use that helped to explode the popularity of messengers until we find that most people use at least one. Messengers are also great for keeping in touch with business contacts, family, friends, among many other uses. One of the earliest messenger service called ICQ had a random chat button that would find you someone to chat to, or indeed allow them to find you. Social Networks Like them or loath them, social networks found their place as the heart of meeting people on the internet. At first they were places to link up with your friends and share information about you what you were doing, how you felt, where you were, or indeed where you werent (such as working). Social networks soon snowballed into a giant productivity eating monster. If you havent heard of social networks then hello, and greetings under-rock person. Some of the more well known include LiveJournal, MySpace, Facebook, and Bebo. LiveJournal mixes blogging and social networking, Facebook has become synonymous with social networks, MySpace synonymous with controversy and Bebo was huge in the UK then fell out of favour with users. The phenomena of keeping in touch with contracts led to new companies trying spinnoffs of the idea. One of these Twitter lets users post short messages of up to 140 characters. These tweets can then be read by followers. Like them or loath them, social networks app ear to be here to stay. Work Rather than have separate disjointed categories, lets lump everything thats done for the sake of work together. It can be emails, video conferencing, virtual conferencing, social networking, messaging. If your work requires you to liase with anyone at all over the internet then theres always the chance of meeting someone you hit it off with. It happens all the time. Friends Friends are always looking out for you. If youre single then you can guarantee that your friends are looking out for someone to hook you up with. On the internet this behaviour is no different. Dating services Dating services started off as simple catalogs of user-made profiles, that could be searched according to any criteria. Paying users could then contact the users they found interesting. Growing from these primitive early systems, they added features such as live chat, messenger services, social networking and so on in order to stay ahead of competing services. Their combination of the best ideas found on the internet to provide the optimal environment for users to meet each other, and maintained the value of the service so that people would continue to pay. Dating services have been one of the leading drivers of growth. Similarly theres also a lot of overlap between dating services and other internet services such as social networks. Online Universes Pushing internet interactions further into the futuristic vision of cyberspace, online worlds give us the Neuromancer vision of cyberspace. Gamers were among the first to explore online universes. The advent of massively multiplayer online games (or worlds/universes/spaces) collectively known as MMOs added a new dimension to the internet. The earliest were game worlds, where users had no set goals, other than lead a double (and supposedly exciting) life as a mage, wizard, ranger, space pilot or any number of alternative personas depending on the game. These evolved, and soon virtual universes began to appear which played down gaming aspects and played up its usage as an alternative universe. Second Life proved to be one of the most popular, and its name captures the spirit in which many of these new universes were formed. Others, such as Entropia Universe grew out of games, but diversified into a platform for delivering anything the partner company could imagine (by renting out world ). In these spaces, you can wander through virtual towns and meet peoples avatars as they in turn go about their business. Avatars are, to steal a description from the matrix films, the mental projection of your digital self. People customize their avatars and in doing so reveal a lot about themselves. Interestingly, people behave similarly to the way they do in real life, albeit with less inhibitions. Sociologists have a great time studying virtual worlds because of this, but that is a story for a different article. Virtual universes however are a little too gamelike for some of us. A more recent addition to the virtual universe landscape called IMVU cleverly combines messenger services with Virtual Universe services to create a hybrid that has found a more mainstream popularity than other virtual worlds. Users can keep in touch through a messenger like contact list, or use its social network-like website, and chat to users in virtual rooms. Unlike virtual worlds, there is no walki ng around. You can move your avatar around, but only to fixed locations called nodes. Standing nodes feature in all rooms, and adding furniture adds more nodes. A couch will come sitting nodes, and some furniture includes nodes for couples to sit snuggled together. Removing the ability to walk around, kept IMVU simple enough that the virtual universe features didnt overwhelm the chat features. Users can buy new rooms, furniture, clothes, pets. They can also buy streaming music to play in their rooms. People meet in virtual universes all the time. Sometimes they even get married in the online universe. Often they get married and then quickly split. Sometimes couples take their relationship further, and meet in real life. Does it work? Implications Dangers Anonymity Conclusion What are people looking for? When asked the question: For me, dating is mainly about.. ? in the top dating tips survey, the most popular answer was simply love, edging ahead of the rest with 21% of the votes. Surprisingly, next came Marriage and Sex with 19% each. 1. Love 21% 2. Marriage 19% 3. Friendship 8% 4. Partnership 6% 5. Sex 19% 6. Company 3% 7. Social life 3% 8. Romance 12% 9. Conversation 3% 10.

Essay on Sacrifice in Sir Gawain and the Green Knight :: Sir Gawain Green Knight Essays

Sacrifice in Sir Gawain and the Green Knight  Ã‚  Ã‚   There are many different types of heroism that exist among the heroes of past and present. Heroism usually is thought of as battling and triumphing over an obstacle, or conquest of a fair-maiden’s love. But notice what this passage from the Mahabharata says about â€Å"The True Hero.† Heroes of many kinds are proclaimed: hear from me, then, their goals. Rewards are assigned to the families of heroes and also to the hero himself. Heroes of sacrifice, heroes of self-control; others who are heroes of truth; heroes of battle are also proclaimed, and men who are heroes of giving. Others are heroes of intellect, and heroes of patience are others; and also heroes of honesty, and men who live in tranquility . . . There are forest-dwelling heroes, and householder heroes, and heroes in the honoring of guests. (Mahabharata XIII.74.22-27) Sir Gawain and the Green Knight encompasses every point brought out in the Mahabharata about what a hero truly is. Sacrifice is a quality that many persons choose to ignore. But Sir Gawain, throughout the book, magnified this virtue to its extent, even to the brink of death. When the Green Knight challenged the knights of King Arthur for a game, and King Arthur volunteered, it was Sir Gawain who stepped in. Sir Gawain was quick to explain to Arthur, â€Å"When a challenge like this rings through your hall/To take it yourself . . . For battle. Think of your bold knights,/My life the least, my death no loss. . .† (58). Of course all of King Arthur’s knights were valuable to the kingdom, so the phrase of â€Å"my death no loss,† merely meant that the kingdom of King Arthur would continue without Sir Gawain, but it would not continue with the death King Arthur. Sacrifice continued to play a part even to the halfway point of the book and beyond. Such as that of sacrificing the pleasures of a woman which quite possibly was the greatest of all sacrifices, one that we know Sir Lancelot would have failed at miserably. This sacrifice would indeed save Sir Gawain’s life at the end of the story. Throughout the three days spent in Bercilak’s castle, Morgana tried to seduce him, but each and every time he refused (86-90). From line 1830-1865 (104) we read of one moment that Sir Gawain’s virtuous ways faltered.

Samsung Yemen Lcd Tv & Its Accessories

SAMPLE MARKETING PLAN FOR SAMSUNG 3D TV â€Å"Inspire the world, create the future. † 1. 0 Executive Summary Samsung Electronics has proven to the business world that they are one of the most prestigious technology companies in the industry. With more technology advancements than our market can handle at this point and time, Samsung has paved the way for the future in electronics. One of the most popular new â€Å"toys† in the market today, is the unbelievable 3D TV. The first 3D TV was launched in March of 2010, and has already had a major impact on the market.Samsung dominated the market, controlling nearly90% of the total share. Samsung’s  product, the 9000 series TV, is  incomparable to competition with its ultra-thin screen, measuring only 0. 3 inches in width. The 9000 series also comes with a full color spectrum that makes for an  incredible viewing experience. 2. 0 Situation Analysis Samsung’s current strategy in the 3D television market is t o seize a dominant market share while the market is being pioneered and to maintain the majority market share throughout the stages of the 3D television life cycle.With the recent release of 3DTVs into the market in early 2010, the product is still considered to be in the introduction stage of the product life cycle. While Samsung introduced its  new slogan, â€Å"Inspire the world, Create the Future,† the company's strongest emphasis in the last two years has been on convergence and  integration. Samsung has re-organized their  corporation to encourage cross-pollination and innovation. This is demonstrated by the progressive approach to the market that Samsung has taken, acknowledging the lack of immediate growth in the market, and innovating to prepare for the potential growth in the market.Targeted Segment With the development of 3D TV technology, Samsung’s target market is easily identified as the Early  Adapter. An early adapter is a  consumer who has a very quick rate of diffusion, the rate at which the market accepts a new product or product idea. One Strategy Analytics Survey identified â€Å"Cube Tubers† as the most likely consumers of  products available in the 3D  TV market. â€Å"Cube Tubers,† are twice as likely to express interest in receiving 3D TV  programming at home. These consumers represent a  rather small eight-ten percent of the overall  population.They are most likely  young, mid-twenties to late thirties Caucasian males,  educated and married. They seem to be the  most likely candidates to show interest in buying the newest generation of the television market. Along with the â€Å"Cube Tubers,† the broader target market tends to be families with young children. The target audience for 3D TVs will mostly be  found in or near  bigger cities. These locations must be  considered the prime market areas due to the likelihood of the availability of 3D content in urban areas rat her than away from cities in the more technologically  constrained rural areas. Competitive Analysis . Sony cooperation 2. Mitsubishi Inc. 3 . Panasonic Inc. 4 . LG Electronics Inc. 5 Vizio Inc. 1 Sony Corporation Sony is a Japanese company that uses web advertising as a dominant feature. They offer different videos and PDF documents on their websites to help customers understand their business. When typing into Google,  Sony does not come up  first, however, Best Buy was one of  the leaders, who sell  Sony TV’s. Sony finds itself in the top five of the market share of the previous trends of the television market, usually in the top three until recently being bumped down to fifth recently in the FPTV market. Mitsubishi Inc. Mitsubishi Inc. is also a Japanese company  with a Very broad product mix, and a marketing theory that anything is possible. They Aim to release their 3D TVs mainly through private company sales rather than in nationally acclaimed retail stores like most brands. Mitsubishi has continued to  use and perfect DLP technology, created by Texas Instruments, while Samsung has moved on from DLP and has released some beautiful Plasma, LCD and LED  3D TVs.Mitsubishi’s difference is  in its picture quality,  although DLP offers great picture quality the technology has many drawbacks such as bulb replacement and interior cleaning to maintain picture quality that hinder consumers from buying their product. Mitsubishi is the most recent follower of trends by recently adopting the Smart TV  idea and integrating Internet  connectivity into the unit. .3 Panasonic Inc. Panasonic, another Japanese company, is another competitor finding its way to the top three market shares in the TV market.Panasonic aims to be  the No. 1 Green Innovation Company in the Electronics Industry by 2018, the 100th anniversary of their  founding. After Samsung initiated an unexpected price war with Panasonic  at the opening of the 3D mark et, they announced an expectancy to miss sales targets for the first year. Demonstrating Samsung’s sound knowledge of good pricing strategies keeping competitors on edge. Panasonic’s premier 3D product differs in  the backlight composition, opting to use plasma for the  opening of the 3D market. LG Electronics Inc.LG Electronics is a Korean company. LG Electronics Inc. , ranking as the world's second-largest maker of flat-screen TVs,  said it aims to strengthen its presence in the burgeoning 3D TV market, seeking to grab a share larger than its target for the liquid-crystal display (LCD) TV market. LG is eyeing 25  percent of the global 3D  TV market this year, which amounts to 950,000 sales based on an annual market forecast of 3. 8million units. That compares with LG's 15  percent market share target for  LCD TVs, or  25 million units. LG had focused on the  mass market.Initially LG’s objective  was to create footprint among the sizable mid dle class, and other than its aggressive pricing, little to  distinguish it from  other consumer durable companies. 5 Vizio Inc. Vizio is a market share leader in the industry, but its claim to success is in its ability to follow  technology and market trends. Vizio’s vision is to be the industry leader  in consumer electronics by consistently delivering the latest technologies at the most affordable price. Vizio has developed cost efficient production methods that allow them to undermine the quality of the products slightly and the price for what they sell at  significantly.SWOT Analysis Strength A. High Quality Innovative Products – Brand Prestige Samsung’s 3D TV market products lead the  industry as they have pioneered the launch of the  new market segment in  early 2010. Samsung’s LED TV product line has earned the prestige of the best picture quality available in the market by Consumer Electronics Reports. Those very products are  a lso leading the  way in innovation in the way of style and appeal to consumers, as Samsung released the 9000Series, which is the  thinnest 3D TV available at  . 31 inches.Samsung is a strong corporate brand known  for its quality products and  advanced technology use. The brand prestige that Samsung looks to carry over from the LED, LCD  and Plasma markets, hoping consumers will easily identify the brand and associate it with it high quality products from an organization dedicated to providing  market leading products. B. Availability of Resources Samsung recently transferred 300 engineers from their very prominent semiconductor business unit within the organization, and established a new television business unit.The relocation of these engineers has  allowed SE to develop market products far beyond the technology and innovative capacity of competitors. C. Constant Focus on R;D Samsung Electronic has been regularly strengthening its research and developments (R;D) fu nction. The company devotes significant resources and attention to develop consumer-preferred  products with innovative and distinctive features. It is evident from the fact that, the company invested approximately 5. 0% of its revenue in R;D activities  over 2008 and 2009. 2 WeaknessesA. Lack of Association with 3D Gaming Content Unlike SE’s competitor Sony, Samsung does not have a direct association with content provider for 3D gaming. Acknowledging that the 3D gaming segment will account for a substantial market share, one could infer Sony’s association with gaming consoles like PlayStation as  a competitive advantage over Samsung. B. High Quality, High Price Understanding SE prides itself on having very high quality products, one can infer that SE can  justifiably charge the highest price for those renowned products.To maintain a dominant market share as the market for 3D TVs expands, SE’s establish target consumer will  have to expand. With the  target consumer established economically as the upper level of the middle class and all levels of the upper class currently, the target will have to expand to incorporate all members of the middle class. 3 Opportunities A. Strategic alliances that enhance the company’s product offerings Samsung Electronics has entered into strategic agreements with some of the well-known companies of the world in the recent past.For instance, during June 2009,the company signed a patent cross license agreement with Toshiba for semiconductor  technologies. Toshiba is the leading player in the NAND flash memory market with thousands of patens under its  name. Toshiba is also in the forefront of innovations in this product category with several new technologies under its credit. By signing the cross licensing patent agreement with Toshiba, Samsung Electronics continues to have access to important NAND flash process technology as well as multi level cell flash memory design IP relevant for f uture NAND flash generations.B. Partnership to access 3D gaming content Establishing a partnership with a company in the video game industry would be ideal to increase the amount of 3D gaming content. Although this segment of  the market is currently minimal, the surplus of content could influence consumers so that the segment could increase. A partnership with a company  like Microsoft could have an impact on the market  greatly. The timing of this opportunity would be immediately, the sooner the partnership begins, and the sooner the content could be produced, presenting an opportunity  for the market  to expand. . Threats A. 3D Gaming Market – Sony The fact that Sony offers the PlayStation gaming console, they have a foot in the door with the consumers who have interest in 3D gaming, which could potentially represent a significant share of the market. Sony’s PlayStation is the first gaming console to launch 3D gaming  content. This relationship between t he two products allows Sony to sell both products together at a discount offering not only a product to view 3D content, but also a gaming console with abilities that allow consumers to play3D games.

Exposures, Financial Contracts, and Operational Techniques Essay

Exposures, Financial Contracts, and Operational Techniques - Essay Example As the research declares the transaction exposure can be hedged through three types of contracts: forward market hedging, money market hedging, and option market hedging. The forward market hedging supposes to enter into a derivative contract when the object of the transaction exposure is determined. The contract from the derivative market will be liquidated with the funds obtained from the spot market. According to the paper findings in a money market hedge, the company which is exposed to transaction exposure borrows or invests in one currency and exchanges the proceeds for another currency. The proceeds for the loan or saving account are related to business operations when the hedge is covered or they are purchased from the market at the end of the contract when the hedge is uncovered. Operating exposure can also be offset by considering changing financing policies: using natural hedges, using back-to-back (parallel) loans, and using currency swaps. The first method considers matching the currency cash-flows. The success of this practice depends of the predictability and low volatility of cash-flows. Back-to-back loans are agreements between companies from different countries to borrow each other domestic currency for the period of contract. It is actually a credit swap, because the two companies borrow the currency which will be repaid.

Past President IN Current Times Essay Example | Topics and Well Written Essays - 500 words

Past President IN Current Times - Essay Example This also brings a problem since that the next generation will suffer since there will be little finance. Thus, management should be worried about the economy. John Kennedy was a democrat, and he was able to balance his power effectively both as a President and a conveyor of public interest. While exercising the power he had as a president, he always thought about the general welfare of the people. Bureaucracies suffer from political influence (Hald-Mortensen ), which becomes a problem especially if there is incompetent leadership. There should be a distinction between administration and the political sector for there to be an assurance of effective bureaucracy run by democracy. President Kennedy was courageous and made hard and competent decisions. He went for a strike on behalf of his country against the titans who had hiked steel prices, until it amounted to a rational price. There is a problem in making decision as to abolish parole in America. The parole authorities should stand firm and be courageous in the decision they will make in future. For a country to prosper, leaders should rule using democracy, be courageous in each decision they make and also be concerned about the universal welfare of the

Trouble-shooting for social media Research Paper

Trouble-shooting for social media - Research Paper Example This will enable the Social media director to deliberate on object course of action in case something goes wrong. The hashtag was used for about two hours after when they realized that it was leading to negative publicity. Unfortunately, McDonalds Social media director, Rick Won pulled off the hashtag and admitted that it had failed in achieving the intended purpose. Instead of pulling down the tweets, they could have used them from a public relations point of view to turn the negative publicity into positive publicity. Policies should be put in place to deal with the negativity instead of pulling down the negative feedback. This can involve responding to individual customers who left negative feedback and engage them on the services and products offered by the business. At the end, many of such customers end up becoming loyal customers, pin down their initial negative feedback and instead post positive feedback. McDonald failed to track what their customers were posting on other social media sites. Even after the hashtag was removed, the public continued to outburst with a lot of unintended stories in Facebook and Instagram. Failure to monitor such action led to continued negative publicity despite pulling down the hashtag on twitter. McDonald should put in place a social mention tracking tool which monitor what customers are saying about their brand on other social sites. They will enable them respond to emergency situations before significant damage is

The Role of the Holy Spirit in the Sacrament of Baptism Essay

The Role of the Holy Spirit in the Sacrament of Baptism - Essay Example The general use of purification in the pagan manner of worship means cleansing before entering the temple, after engaging in warfare, before handling of idols which they considered sacred, and to put oneself in a spiritual position. Christian baptism basically is for the purpose of cleansing the person so that they may receive the Spirit of God (Thomas, 2008). Washing which was done by immersion in some pagan religions was the first step in the ceremony of initiation and it was concluded with a meal (Edward, 1994). This seems to resemble the cleansing done before the Eucharist or communion service, and even though the two are not presided by an immersion, the purposes of the cleansing seem to resemble each other. There was also a myth surrounding the idea of immersing that the god Thetis immersed people completely to make them invulnerable holding them only at the heel but having all other parts of the body immersed. John13:9 narrates about John asking Jesus not to only wash his feet , but also his whole body. John the Baptist baptized Jesus at Aenon where there was much water which implies that it was an immersion whereby the whole body needed to be covered by the water. In the beginning of all of the four Gospels, the phrase â€Å"baptize with the Spirit† is found eight times and John the Baptist promises that the one coming after him was to be baptized with the Holy Spirit and fire. The symbolic meaning of fire was judgment, since Mathew3:12 and Luke 3:17 narrate, â€Å"His winnowing fork is in His hand, He will clear His threshing floor and gather His wheat into His granary, but the chaff He will burn with unquenchable fire†. Fire and judgment were associated, for example, by prophets as they preached, as shown in Amos7:4 and Malachi 3:2 (Killian & Montague, 1994). Other prophets, like Jeremiah and Isaiah, also mention fire and judgment in their prophesies, denoting God’s judgment. Commentators then argue that the Holy Spirit mentioned b y John during his ministry of baptizing in the Jordan was the Spirit of repentance and preparation so as to receive the Messiah and escape the fire of God’s judgment, and also to be prepared for ministry, when one underwent the ritual with true repentance. The baptism of Jesus in the river Jordan, the subsequent descent of the Holy Spirit, and the confirmation by God that He was God’s beloved son are the same steps today that a Christian follows, being purified or being initiated, being empowered by being filled by the holy Spirit to perform ministry in the Kingdom of God as a son in the Kingdom (Edward, 1994). Jesus also calls His suffering and death on the cross baptism, as found in Mark 10:38 -39. The reason for this use of the term â€Å"baptism† is because the suffering is looked upon as a bath into which Jesus was to be immersed. The view is that the death of Jesus was God’s way of dealing with mankind’s sin; a judgment gives more reason wher e the passion of Christ is referred to as a baptism (Killian & Montague, 1994). This inclusion of this aspect in St Marks Gospel also demonstrates that the Holy Spirit’s baptism of believers is not only for ministry empowerment to heal and cast out demons, but also to enable them to have the Grace to offer their lives as a ransom for many, due to the fact that Jesus is their role model and that he stated they were to drink the same cup He drank.

Prior Knowledge That Is Required before Using the Toaster Essay

Prior Knowledge That Is Required before Using the Toaster - Essay Example The memo is summed up in one page and also contains the name of the group members. A toaster is an electronic gadget that allows you to cook, bake, and boil your food. It is important to have a toaster in your house but before buying a toaster one should decide on whether to buy a basic toaster or a toaster oven. A toaster oven can do more cooking than the ordinary toaster so if you do a lot of cooking then the toaster oven is ideal for you. If you want to cook for a crowd of people then a toaster oven will most likely suit you more than the normal oven. A toaster oven is not very different from the normal oven that is found in most of the kitchens. However, it should be known that not all cooking can be done using the toaster oven and so some cooking should be done using the normal oven or cooker (David 8). When you buy a toaster you are given a short wire cord to prevent the chances of tripping in the event where someone becomes tangled with the wire. However, longer cords are available but should be used with a lot of care. When one uses a longer cord, it is advisable that one checks the marked electrical rating and make sure that it is twice that of the toaster oven. The appliance always has a polarized plug and so this makes it safe especially for fitting it to a polarized end. If you try to fix it and it does not fit then contact a qualified electrician and never try to force it (David 34). A toaster makes toasting much easier and faster than before. The toaster also has an easy to clean interior that wipes the interior of the toaster clean at once. The toaster is also big enough to let you bake an entire meal once without having to split the number of cooking. Baking: this is the function that can be used the same way that you would use your normal kitchen. When baking using the toaster, remember to prepare what you want to bake then preheat the toaster for five to ten minutes.  Ã‚  

“How we discourage creativity” The creative spirit Essay Example for Free

â€Å"How we discourage creativity† The creative spirit Essay Evaluation is the polarization of the learner’s work by a particular set of criteria introduced by the teacher (Goleman, 1992). This can be as simple as commenting on what type of art work is good and what type is ugly to an early learner. While the learner’s work would have to be evaluated sooner or later, doing so too soon might constrict the learner’s ideas of what is â€Å"good† and â€Å"acceptable† as well as what is â€Å"bad† and â€Å"ugly† on as narrow a perception as that provided by the teacher. While this does train the learner to â€Å"do as told†, and conform to generally acceptable measures, it is insensitive to the idea of diversity and freedom of action. When kids are made to worry too much about whether they’re doing things right or not, they become too afraid to try new things that â€Å"might not be right† in their teacher’s eyes. Rewards are positive motivations given to learners in either tangible or intangible means (Goleman, 1992). These can be tangible rewards such as candies or toys or intangible ones such as praises. Giving rewards motivates the learner to continue doing whatever tasks in the same manner as in order to continue getting rewards. The problem is that excessive use of rewards would take away the simple joy of the activity from the child. The child will not wish to experiment with the activity and be more creative since the objective becomes doing exactly as the teacher says in order to receive the rewards. Furthermore, if the learner simply looks forward to the rewards, no attention will be paid on the value of the activity itself which supposed to inculcate lessons that should remain even after the rewards are gone. Competition is placing two or more learners in a situation where some of them could â€Å"win† while others would â€Å"lose† (Goleman, 1992). This makes children step up to the challenge by motivating them with the prospect of outdoing one another. This could train students to answer the teacher’s questions faster if only the first person to answer could win a prize. However, holding competitions as part of learning activities is insensitive to the fact that children learn differently and should be allowed to learn at their own pace. Instead of forcing every learner into a competition where they would have to play by the teacher’s rules, the teacher should find out how each of the learners learn best and provide a proper atmosphere for each to develop creatively in their own time. Restricting choices is limiting the possible activities that a learner could do in order to explore a particular subject matter (Golema, 1992). This could be as simple as disallowing a student from using certain colors when drawing a picture. It is the learner’s curiosity that leads him or her to enjoying activities and learning from them. Limiting the choices that a learner can make limits the places where curiosity could go, thereby limiting creative learning in general. While it is true that this gives focus to the learner, it takes away the possibility of exploring avenues that could also be enriching experiences. Reference Goleman, K. (1992). â€Å"How we discourage creativity† The creative spirit. Vol. 3 No. 2 pp. 61-62.

P2 Cycle in WDM Networks

P2 Cycle in WDM Networks P2-CYCLE IN WDM NETWORKS M.DILEEP Smt K .APARNA Abstract The Failure Independent Path Protection (FIPP) p cycle is efficient scheme. If failure occurs in pre configured cycle it is protection is reconfigured between those two nodes. In this paper we use Parasitic Protection Links (PPL). PPL’s are p-cycles with have attached links. PPL’s are used to protect the not only failure nodes but it connected to PPL to cycle. P2 cycle is known as p cycle with parasitic protection links. We address The P2 cycle in mesh networks can be analysed by using single link failure. We further propose two P2-cycle based heuristic algorithms, Strict Routing Protection (SRP) and Flexible Routing Protection (FRP), to address the dynamic traffic case. In the dynamic case, both SRP and FRP outperform FIPP p-cycle schemes in terms of blocking probability in most scenarios considered. In general, the P2-cycle protection scheme outperforms the p-cycle based in terms of capacity efficiencies which being slightly slower in terms of traffic recovery speed. Key words: Parasitic Protection Links (PPL), Strict Routing Protection (SRP), Flexible Routing Protection (FRP). I. INTRODUCTION Network survivability, defined as the Continuous operations of network are performed in case failure occurred in the network [3]. In generally optical networks carry information in terabytes. A failure in network causes lot of loss of data. Ring based networks can easily come due to their structure and fast recovery management. In ring based it takes 50-60ms but it gives capacity redundancy high. As mesh based networks emerged, more capacity efficient protection schemes were proposed which allow backup capacity sharing. These schemes are into three categories: link-based, segment-based and path-based [29]. Link-based protection schemes produce the fast traffic recovery speed but suffer from the worst resource efficiency . Best resource efficiency is achieved by path based protection scheme. Shared Backup Path Protection (SBPP) is one of the path protection schemes. it is high capacity. upon a network failure. It takes long time o recover from traffic. Segment based protection schemes lie between the link-based and path-based schemes, and offer a better combination of bandwidth efficiency and recovery time. Path-based protection schemes usually achieve the best resource efficiency. Among them, a path protection scheme, namely, Shared Backup Path Protection (SBPP), was shown to be the most capacity efficient protection scheme [8]. However, it suffers from long traffic recovery time upon a network failure. Segment based protection schemes lie between the link-based and path-based schemes, and offer a better combination of bandwidth efficiency and recovery time . The pre-configured protection cycle is known as p-cycle, combines the good qualities of mesh and ring based protection schemes and achieves the recovery speed of ring- based with the capacity efficiency of mesh protection. P-cycle has been proven theoretically to be the most efficient pre-configured protection scheme in terms of capacity efficiency and recovery speed . II. Dynamic Traffic Scenarios In dynamic traffic without the prior knowledge of arrival time of future requests. Due to the pre-configuration property of traditional p-cycles, it is extremely difficult to re- provision all the protection cycles whenever a new session arrives in order to minimize overall cost. Each provisioning takes large computation cost and complex network reconfiguration. Therefore, most of the work in the literature assume that established p-cycles should not vary with time or traffic. The authors in proposed three different routing algorithms along with link-based p-cycle protection scheme to deal with dynamic traffic. The results indicate that the proposed p-cycle based design performs better than SBPP in dense networks but worse in sparse networks. Protected Working Capacity Envelopes (PWCE) is another method to address dynamic traffic scenarios. It divides the entire network into two partitions: working and protection. Both static and dynamic traffic can be accommodated as long as the tot al traffic do not exceed the limit of working envelopes. Although some decent results have been shown in the literature, p-cycles still have such intrinsic weakness in dealing with dynamic traffic. If an incoming session whose end nodes do not lie on any cycle, it cannot be protected and a new cycle has to be constructed to protect this session, or the existing cycles must be reconfigured. An example shown in Figure 4.2 illustrates such weakness and also reveals the advantage of P2-cycles. In Fig. 4.2(a), session1 has been provisioned and protected by cycle C1(ECBFE). As session 2 arrives, the primary path of session 2 is provisioned as P2(ABCD). Under FIPP p-cycle scheme, cycle C1 cannot protect it and thus a new cycle C2(ABCDEFA) is constructed to protect it as shown in Fig.4.2(b). However, instead of building a new cycle, using P2-cycle approach we can add two PPLs (A,F) and (D,E) to connect the end nodes of P2 such that C1 can also provide a protection segment (AFED) for P2 as shown in Fig.4.2(c). Therefore, both sessions are protected by a P2-cycle with much less cost. Fig 1: P2-cycle deals With Dynamic Traffic III. Problem Statement In dynamic traffic scenarios, a WDM mesh network is given with network resources, such as the maximum number of wavelengths and the cost on each span. Each traffic request arrives to the network in a dynamic fashion such that it needs to be considered individually based on the current network status. The network status consists of the detailed working and available wavelengths on each span as well as all the accepted sessions and P2-cycles provisioned in the network. Given a network modelled as an undirected graph G = (V;E) where each undirected span e2E has a cost ce, the current network which includes the currently used and available wave- lengths on each span e, each accepted session l and their protection P2-cycles. Provision incoming unicast sessions against any single-link failure with the minimum overall blocking probability by using P2-cycle scheme. The assumptions required in this dynamic traffic case are the same as that in the static case. We design two heuristics to address the dynamic traffic case. In the first method, named Strict Routing Protection (SRP), the primary and protection path for each incoming session are computed separately. The primary path is firstly provisioned using Dijkstras shortest routing algorithm. Based on the primary path, either an existing P2-cycle or a new cycle is found to protect it. In the second method, named Flexible Routing Protection (FRP), the primary and protection paths of an incoming session are constructed jointly. The existing P2-cycles will be preferred to being used first. If no existing one is able to protect the session, a new cycle will be formed. We allow spare capacity sharing between different sessions to increase the capacity efficiency. A. Strict Routing Protection (SRP): The motivation of SRP is to always choose the shortest path to route the primary traffic in order to leave more spare capacity for protection, since the capacity used for primary path cannot be shared among different sessions. And then we check whether any available P2 cycle can be exploited to protect this newly established session. Once being set up, the cycle for a P2-cycle cannot be changed. The protection links that are added to PPL’s are one hop away from end nodes. The detail of the algorithm SRP described in following steps: 1. As a new session dl(sl; tl) arrives, establish the primary path fl between sl and tl under current network status by using Dijkstras algorithm. If it fails, the session is blocked; 2. Sort all the existing P2-cycles, cp â‚ ¬ C, in the increasing order of (dl; cp), which is One hop indicates that there exists a span in the network that connects a node to the cycle. If (dl; cp) = infinite 1 for all cp â‚ ¬ C, then no existing cycle is able to protect this new session. Thus, a new cycle needs to be constructed to protect dl. 3. For each existing protection cycle, cp, we construct a temporary graph G0, consisting of only the cycle spans of cp and all the spans connecting the source and destination nodes of l to the cycle . All the spans used by fl should be removed to ensure that its protection path is link-disjoint. Then, all the sessions protected by cp are checked and if an existing session in D can share the same cp with the new session l, we should make sure that either their primary paths or their protection paths are link-disjoint. we remove the protection paths of all the sessions in D whose primary paths are not link-disjoint with fl. If a protection path can still be found in the remaining G0 this protection path will be ql for l. Accordingly, the protection cycle is also determined, which should be updated if some PPLs are also used. 4. If every existing cp fails to protect dl, a new cycle will be constructed to protect it. We first attempt to find two diverse paths to form a cycle that is link-disjoint to fl. If such cycle cannot be found, then we find a path, ql, link-disjoint to fl and the cycle is formed by combining ql with fl. B. Flexible Routing Protection (FRP): Different from SRP, the flexible routing protection scheme considers primary and protection paths jointly for each arriving session. Instead of determining the primary path in advance, we examine each existing P2-cycle and find each potential protection path along the cycle that can connect the source and destination. For each potential protection path, we try to discover a primary path for it. If it succeeds, the session is accepted. Otherwise, a new cycle is constructed to protect the session. Flexible Routing Protection (FRP) Scheme Algorithm FRP is explained in following steps: Given a new session dl(sl; tl), all the available P2-cycles cp â‚ ¬ C are sorted in the increasing order of (dl; cp). For each available cp, list all the possible protection paths for dl. If the end nodes sl and tl are on the cycle, there are two possible segments along the cycle. If sl or(and) tl is not on the cycle, the path will be composed of parasitic links connecting sl or tl to the cycle and an on-cycle segment. We assume the average node degree in a given network is denoted by  µ. Each cycle can provide two on cycle segments between any pair of on-cycle nodes. Each end node, sl or tl, can be connected to the cycle by at most  µ PPLs given the node degree  µ. Hence, the average number of candidate protection paths provided by any P2-cycle For each candidate ql, run Dijkstras algorithm to find a primary path fl in G that is not only link-disjoint to ql but also link-disjoint with other primary paths protected by the same cycle if their protection paths are not link-disjoint. If it succeeds, we store the combination in a temporary set T, which is initialized as ;. After checking all the existing P2-cycles, we check set T and find the combination with minimum cost of fl. We recover the spans removed from G and update the network status. If no existing P2-cycle can be used to protect session dl, we use Bhandaris algorithm to find two link-disjoint paths between si and ti to form a new P2-cycle. If it fails, the session is blocked. Otherwise, the session is accepted and one of the paths (usually the shorter one) is used as the primary path fl, and the network is updated. IV. Results for Dynamic Traffic Based on two P2-cycle protection algorithms, SRP and FRP, proposed for provisioning dynamic requests, we conduct a simulation study to compare the performance of these algorithms under dynamic traffic. The networks used in the simulations are NSFNET, COST239 and USNET, in which USNET network, shown in Fig. 2 has 24 nodes and 43 edges and the average node degree is 3.58. Fig.2 USNET(24 nodes, 43 edges) In each simulation run, 1000 randomly generated unicast requests are loaded to the network sequentially and the reject ratio is recorded. The arrival of traffic follows Poisson distribution with  ¸ requests per second and the duration of an accepted connection is exponentially distributed with a mean of  ¹. The traffic load measured in Erlangs is ÃŽ »Ã‚ µ Each connection requires an entire wavelength to transmit the traffic. The maximum capacity on each network link is set to 16 wavelengths. Figures 3,4,and 5 show the blocking probability of dynamic traffic using SRP, FRP and FIPP p-cycle in NSFNET, USNET and COST239 networks, respectively. Each point in the figures is the average value of 200 simulation runs for each traffic load. For FIPP p-cycle scheme, the primary path of each arriving connection is provisioned first by using Dijkstras algorithm, and then protected by a p-cycle. Fig 3(a):Comparison of blocking probability in NSFNET(W=16) Fig 3(b):Comparison of blocking probability in COST239(W=16) Fig 3(c):Comparison of blocking probability in USNET(W=16) The results show that both SRP and FRP achieve lower blocking probability than FIPP under most of the network scenarios. In NSFNET, SRP achieves better performance than the other two schemes. In USNET, FRP outperforms SRP and FIPP under every scenarios. In COST239, however, SRP and FIPP achieves the same session blocking ratio, which is better than FRP, when the traffic load is relatively low. As the traffic load increases where the network is very saturated, FRP turns to perform better than SRP and FIPP. Based on the results, SRP performs better than other two schemes in relatively small and sparse networks at a low level of traffic load. FRP achieves the best performance in larger and denser networks, especially when the network is very saturated. One of the reason that SRP performs better in small and sparse networks, such as, NSF, is that to provision a session always using the shortest path will save some capacity for protection in a long run. Hence, more capacity can be used for protection such that more cycles can be established. in a network with high nodal degree, a cycle is more likely to reach a large group of nodes compared with a sparse network. In this case, FRP has a higher chance to protect a given session by using existing P2-cycles when network load is very high and the network is over saturated. Fig 4(a).Comparison of NOR in NSFNET(W=16) Fig 4(b).Comparison of NOR in cost239(W=16) Fig 4(c).Comparison of NOR in USNET(W=16) We also studied the average NOR of each accepted connection as in dynamic traffic scenarios and the results are shown in Figures 4(a),4(b) and 4(c). As expected, FIPP achieves the best solution with exact two node reconfigurations for each connection. Meanwhile, SRP also performs better than FRP in three networks. This reveals that connections protected by FRP use more PPLs than those used by SRP, which follows from the basic concept on which the two algorithms are based. It is worth noting that the average NOR achieved by SRP is almost stable below 2.4 in NSF and USNET and 2.7 in COST239. This indicates that most of the connections only need two no reconfigurations upon a network failure, especially in NSF and USNET. FRP has larger average NOR because it iterates every existing p-cycle in the network to protect each session and choose the one with minimum cost but not the one with minimum NOR. Shorter primary paths always results in longer protection paths such that more PPLs are us ed to protect each session. Therefore, based on the simulation results, SRP and FRP both achieves the lowest blocking probability than FIPP in most of the network scenarios considered and each scheme has advantage over the other in different network scenarios. SRP has better failure recovery performance than FRP. In dynamic traffic scenarios, the P2-cycle protection scheme is faster protection scheme provides an enhancement of capacity efficiency over the FIPP p-cycle with asmall change in the recovery time. VI. Extension The p2-cycles can be extended to link failures can be obtained. If one node can be failed then the data will be passed through alternative paths to reach to the destination. The p2 cycle can be defined as the original p-cycle The protection links that are added to PPL’s are one hop away from end nodes. For p2-cycles the network data can be efficiently transferred to destination which is one hop away from the nodes. V. Conclusions In this paper new p cycle protection is done in mesh based protection networks. By using the parasitic protection links (PPL), FIPP p-cycle can be extended through paths from end nodes which are one hop away from the failure nodes of p cycles. In dynamic traffic scenarios., in dynamic their are two algorithms are proposed Strict Routing Protection (SRP) and Flexible Routing Protection (FRP), to handle dynamic traffic demands in order to minimize the total number of blocked sessions. In dynamic traffic case the blocking probability less by using algorithms SRP and FRP comparing with FIPP p cycles. The numerical results shows the P2-cycle protection scheme is a more highly capacity efficient than the Failure Independent Path Protection p-cycle scheme in dynamic traffic case. the P2-cycle protection scheme is a more effective alternative of existent p-cycle-based and path-based protection schemes, Considering the factors of capacity efficiency and recovery speed References D.
