Civil liberties, habeas corpus and war on terror

Introduction Habeas corpus is one of the legal principles, which constitute the foundation of law in America. The principle enables an individual to challenge detention. This is a vital principle in law whose application has largely depended on regimes, the governance approach and security challenges that a government encounters.Advertising We will write a custom research paper sample on Civil liberties, habeas corpus and war on terror specifically for you for only $16.05 $11/page Learn More Various regimes have applied the principle in different ways (Halliday, 2011). The variation in the application has been controversial with the onset of war on terror (WON). Legal hurdles have impaired WON as regimes seek to hold enemy combatants without any trial. However, the presence of this clause limits the ability of authorities to detain suspects without initiating hearings (Fiss, 2006). The congress and the president have the capacity to lift the right to hab eas corpus. The application of this right is largely dependent on the security challenges that a regime encounters. As such, the suspension of habeas corpus depends on the security challenges that a government is encountering. Definition of habeas corpus With reference to the American constitution, habeas corpus is a vital principle of freedom. The terminology means ‘to avail the body’ in Latin. Consequently, it enables individuals to access freedom from detention without any trial. The American constitution affords its citizenry with the right to plea to this legal clause. In such cases, the American government has to answer to the court. The government has to provide concrete reasons for holding a person. Subsequently, the court determines whether the reasons provided are adequate to allow the wavering of this fundamental right. Habeas corpus in America is much similar to the corresponding law in England. The American law emanated from the English statutes. However, t here are numerous adjustments in the respective nations to suit their circumstances. There are certain reasons that lead to lifting of this right. They include rebellion and protection of public safety. Over years, the application of habeas corpus has changed with countless infringements by authorities (Hafetez, 2011). War on terror The WON has culminated in controversy owing to the government’s detention of civilians believed to be enemy combatants. The application of this vital principle has been violated by subsequent regimes as they seek to detain combatants. The challenge that the government encounters is the prosecution of the alleged combatants in civilian court. As such, the terror charges would not stand before judges and most of the combatants would be set free.Advertising Looking for research paper on government? Let's see if we can help you!

This enables the authority to detain such suspects despite the illegality of such detentions. The Bush administration encountered numerous challenges as it was holding suspected criminals without trial. Owing to this challenge, the Bush regime could not effectively execute its strategies during the WOT. Subsequently, it sought to build a holding camp in a place where the American constitution had no jurisdiction. Guantanamo bay was constructed on land leased from the Cuban authority. As such, the American constitution had no jurisdiction. The government held terror suspects on the island without any trial. The right to habeas corpus was not applicable on this detention camp (Fiss, 2006). Cases challenging detention The action to hold detainees in Guantanamo was challenged severally. In Boumediene v. Bush, the court ruled that Boumediene, a Bosnia and Herzegovina national had the right to plead to habeas corpus. Consequently, his detention was illegal. The court decision culmi nated from 5-4 majority in the ruling. The application of insular cases meant that the American constitution had jurisdiction in Guantanamo since America had complete authority and control over the territory. The decision by the Supreme Court resulted in subsequent cases pertaining to this right. Other suspects sought to plead to this right (Cornell University Law School 2007). However, their efforts were curtailed by legislation. In subsequent cases pertaining to detainees held in the Guantanamo camp, the court ruled that the detention was illegal. Consequently, the government solved the impending crisis by establishing the Combatants status review tribunal. The detainees held in the camp were to face a military commission since the government ruled out trials in civilian courts (Cornell University Law School 2007). Courts’ role in the implementation of habeas corpus In light of the above cases, the court exercised absolute authority on the ability of any detainee to plead t o this habeas corpus. The jurisdiction of the court limited the ability of the defence department to breach this right. However, to some extent the president prevailed since the detainees did not receive the right to prosecution in a civilian court. If the proceeding were in civilian courts, most of the detainees would be set free. This would hinder the WOT since the civilian courts would set free such detainees. The government viewed the prosecution of enemy combatants in civilian courts as counterproductive (Hephaestus Books 2011).Advertising We will write a custom research paper sample on Civil liberties, habeas corpus and war on terror specifically for you for only $16.05 $11/page Learn More Previous incidences of suspension habeas corpus’ The Congress and the president can exercise their authority and limit the right to plea to this right. President Lincoln did so during the civil war when part of America was under enemy forces. The suspensi on of this rights resulted in the establishment of military courts to deal with the rebels that wanted to seize the capital. However, Lincoln faced an aggressive senate once it resumed from recess. The high court in Maryland overturned Lincoln decision pertaining to the right of habeas corpus. However, the president assumed the court’s decision and continued to suspend this right with regard to combatants. Once the senate resumed it passed legislation approving the president’s action. The president’s actions were necessary since American was encountering a rebellion. According to Sir William Blackstone, one of the lords that were pivotal in the creation of this principle the King had to know of any retrains on his subjects. Once the English legal system was fully operation, the legal statues provided that the right could only be waived during a rebellion or an invasion. This is much similar to what the legal statutes in America provide. Similarly, during the Sec ond World War the president could suspend habeas corpus. However, the court limited the suspension of this right to only crimes that relate to war only. If habeas corpus was suspended, the applicable law only applied to crimes pertaining to invasion, enemy combatants and rebellions. In the above scenario, the courts also limited the suspension of this right. This limits the misuse of the suspension of habeas corpus (Fiss, 2006). Congress and the president The congress being the ultimate legislative body has the capability to determine various aspects of habeas corpus. The congress has enacted laws, which determines the application of habeas corpus. Evidently, alterations to this right mainly result from the security challenges that the nation is encountering. The alterations have sought to approve measures to detain combatants or suspects who threaten the safety of America. The congress first altered the right to habeas corpus was during the Lincoln era, when the president suspended this right as the senate was in recess. Despite confrontations in congress, senators ratified the president’s executive order to suspend habeas corpus. The second situation, which required the suspension of habeas corpus, was during World War II (Chemerisnky, 1987). Legal changes owing to WON The Oklahoma and twin towers attacks are other security challenges that have culminated in the suspension of this right. The latter resulted in massive legal changes to deal with terror. However, alterations have encountered challenges if they infringe on the constitutional rights of a person.Advertising Looking for research paper on government? Let's see if we can help you! Get your first paper with 15% OFF Learn More The 2001 presidential military order sanctioned detention of individuals believed to partake in terrorist activities without any legal proceedings to prove their innocence. Legal scholars were opposed to such an order since it violated habeas corpus. Despite the approval of detention based on terrorist suspicions, the Supreme Court proved the supremacy of the rights entrenched in the constitution through various rulings such as Hamdi v Rumsfield. Cases such Boumediene v. Bush and Hamdi v. Rumsfield had dissenting justices. However, it was vital that the court observed the constitution. This is because habeas corpus is a basic right for any person restrained by American authorities. Consequently, suspending it without providing a detainee with a chance at justices breaches the basic rights entrenched in the constitution. Unlike in previous scenarios where the legal system shied away from upholding the law when the executive contravenes it, the court emerged as an independent organ of governance by terming the detentions unlawful (Perkins, 2004). Personal views on habeas corpus Habeas corpus is a key right in any free society. As such, it is vital to uphold it. Despite the complex security challenges that this nation encounters, it is paramount to ensure that all detainees have access to a legal process where they can prove their innocence. Terrorist charges should not be a basis to detain an individual without any legal procedure to try the suspect. Terror poses a massive challenge to this society. Subsequently, on the determination of the involvement of a suspect in such activities, the suspect should face appropriate legal process. Where the suspect is extremely dangerous specialized trial procedures should apply. These include military commissions and tribunals. The constitution of such tribunals should have civilian legal representatives who should ensure that the basic rights of a defendant are upheld. The president and the congress should also exercise ca ution in suspending habeas corpus since it breaches the basic rights in our constitution (Hephaestus Books, 2011). Conclusion In instances where the government suspends habeas corpus, it seeks to address certain security challenges. The details above exemplify the above assertion fully from the Lincoln regime to the Bush era. However, suspension of such a right has encountered legal challenges from courts, which have either outlawed or limited the suspension of this right. Courts undertake a vital role in ensuring that all detainees can challenge their arrest in a court or an appropriate legal system to suit their circumstance. The congress and the president have emerged as key figures in the implementation of this right with the initial passing bills to influence its application. Conversely, the latter issues executive orders to suspend habeas corpus which congress can ratify to ensure legality. Suspension of habeas corpus has exclusively pertained to individuals that pose a signif icant threat to the security of this nation. Conclusively, the suspension of habeas corpus pertains entirely to the security challenges that this nation is encountering. References Chemerisnky, E. (1987). Thinking about habeas corpus.

Early Arkansas Natives and Migrations essays Arkansas and the southwest, January 31, 2003 The Mound builders of the Mississippian Culture The first human inhabitants of Arkansas and North America were the paleo Indians, right after the last ice age disappeared. Survived by hunting the mastodon, saber toothed tigers. Where they came from? The few skeletal remains suggest that they were Caucasoid, were more related to the white races. Some same that they can be related to the Ainu people of Japan. The paleo Indians could have been related to the Ainu people. A great controversy still exists on where the paleo Indians originated. The weapons and tool technology changed between 9 thousand and 8 thousand years ago. Some native Americans today may have paleo Indian genes in their markup today. Their existence ceased to be evident about 8000 yrs ago. The next group of human inhabitants were the Archaic Indians. 8000bc to 1000bc. Definitely Mongolian tribes or bloodlines. On the other hand, they shared cultural traits as the paleo Indians. They were hunter gatherer people. They lived all over Arkansas, we can infer what we know about them come form artifacts that come from bluffs in northern Arkansas. Bluff Dwellers in the Arkansas Ozarks. Fortunately, many articles survived because they lived in sheltered bluffs, . many people have found many artifacts, toward the 19th century. Many investigations were made, and we have many archaic Indian articles from their culture. These give us some information about the archaic Indians way of life. They had no system of writing, or surviving documents to say definitely what their religious beliefs were, afterlife, what was their political organization? No historical records to draw on. It is clear they were hunter gatherer Indians. The archaic Indians had not yet developed the bow. They were hunting deer and elk, and other game that was prevalent. T ...

Transition Of Corporate Power And How It Effect Fashion Industry - Assignment Example The paper "Transition Of Corporate Power And How It Effect Fashion Industry" discusses Transition Of Corporate Power And How It Effect Fashion Industry. In the fashion sector, the corporate should be focusing on the governance so that they maximize residuals and in thecases of investor-owned firms, theyhave to make a pro datadistribution to theshareholders. The pro-data distribution allows accountability when it comes to government subsidies and the role of labor laws and community interest. An example of a transition of corporate power in thefashionindustry is China. China is one of the largest consumers of textile with its population of 400 million, giving a high demand for textile. In the past, the fashion industry has faced problems starting from insufficient raw materials and inadequate technology. In 1950, the Chinese government started it five-year plan with the construction of cotton mills, printing and dyeing plants. The plan was not only meeting the demands of the growing p opulation but also to provide employment. The government solely embarked on the production, structure and distribution. It however failed to meet the requirements of its population, so the government introduced a modernized method of the open policy. Therefore, allowed foreign direct investors to do businesses in China. It also enabled China to renovate its outdated industry rapidly and also make new economic ties with other countries. The result was a transformation of the intermediate products like thread.

TERRORIST TRAINING Research Paper Example | Topics and Well Written Essays - 2000 words

TERRORIST TRAINING - Research Paper Example Over the years, numerous worldwide campaigns have been launched with the aim of fighting terrorism. Terrorist training has been continuously propagated by extremists such as Osama bin Laden and Ayman al-Zawahiri. They are said to be the leadership and minds behind Taliban and Al Qaeda. These terror groups expanded their terror activities by establishing terror training camps in Afghanistan and other regions of the world. Terror training can be blamed for the deadly terror attacks that have been carried out in Europe, USA and other regions of the world. One of the most common of these terror attacks include the 9/11 attacks in the USA. The main aim of this paper is to help readers to understand the way in which terrorist training and recruitment has shifted, changed and evolved over the past decade. Terrorist Training Although there are many issues that define the way in which the world seeks to counteract or avert terrorism, one of the primal means by which governments can seek to di srupt terrorism is by seeking to interfere or stymie the means by which terrorist groups train and/or recruit new members. Ultimately, nations such as the United States have made it a primary goal of its intelligence and/or military to seek to disrupt or destroy terrorist training facilities and capabilities at each and every juncture. In such a way, many analysts have noted that this process in and of itself is more effective in helping to stem the tide of terrorism than targeted assassinations of high ranking terrorists. Nonetheless, when performed in tandem with other actions, seeking to disrupt and destroy terrorist training capabilities comes to be seen as an effective tool in the arsenal of counter terrorism agencies and governments the world over. As a result of the relatively high level of success that the United States and other nations have experienced with regards to depriving these entities of their training capabilities, groups such as Al Qaeda and others have been forc ed to integrate with new dynamics. As such, these new dynamics in terrorist training will be the primal thrust and unit of analysis within this brief research paper. In seeking to understand the way in which terrorist training and recruitment has shifted over the past decade, the reader can come to a more appreciable level of understanding with regards to how these entities continue to be represented within the world. Looking back but a few short years, the reader can note that a far different system existed as compared to what is evidenced now. Taking Al Qaeda as the case in question, it can be noted that there existed defined and extant philosophy of integration with regards to the way in which training facilities existed in and around the globe. What is meant by this is that Al Qaeda operated a litany of different physical training facilities in far flung reaches of the globe to include Somalia, Afghanistan, Sudan, the Philippines and others. Up until the attacks of September 11t h, 2001, these training bases served as the backbone by which newly recruited warriors would learn the basics of how to engage in Al Qaeda’s definition of jihad. It should be understood at this particular juncture that although Al Qaeda represents one of the most salient threats and perhaps one of the best known terrorist entities within the world today, it should not be understood that this group alone

Virus-host Receptor Interactions in Biology

Virus-host Receptor Interactions in Biology Abstract Viruses are obligate intracellular parasites and, as such, must penetrate a suitable host cell in order to replicate their genomes and disseminate. Most viruses are limited to a specific set of cells or tissues in which they can successfully replicate, and this may be in one or more particular species. When viruses are able to bind a variety of cells, the pathogenesis and overall effect on the organism may differ. The main determinants of viral tropism differ between different virus families, but in order to take the first, and arguably most important step, in the infection of a host cell, the virus must attach via specific interactions between cell surface molecules and viral proteins. Enveloped viruses usually have proteins embedded in their envelope, assembled at the host cell surface prior to budding. In the case of some viruses (such as HIV-1), these may even consist of cellular proteins from the host cell itself. Non- enveloped viruses are usually internalized in some way and uncoated in an endosome in a pH-dependant manner. Many viruses require a number of cell surface receptors for cell entry, and it is this combination, added to other factors such as replication proteins, that determine whether or not a virus can penetrate and replicated within a certain cell. Introduction As obligate intracellular parasites, the life cycle of viruses depends on an intracellular replication phase and they are thus dependant on living cells. The first essential interaction a virus makes with a host cell is with a cell-surface receptor. A viral receptor may be defined as any cell surface component that mediates recognition of a cell and facilitates entry of the virus and subsequent infection. Receptors serve to ensure infection by overcoming repulsion between the virus and cell. (Baranowski, Flint, Jindrak, modern virol) Cellular receptors are generally proteins, although other types of receptor, such as carbohydrates, may be used (see table 1). These molecules are essential components of the cell or extracellular matrix and functions may include cell adhesion, signalling e.g. chemokine and growth factor receptors. (Baranowski 2003) While some viruses require only one receptor, binding to one cellular receptor alone may not be sufficient for initiation of infection for other viruses. Viruses may bind two or more receptors in sequence in order to initiate endocytosis or membrane fusion. For some viruses, the first contact with a cell is through a low-affinity interaction with a ubiquitous molecule, which allows the primary receptor-virus interaction to take place. The primary receptor is generally unique to certain cells and therefore partly defines the tropism of that particular virus, as cells are rendered susceptible to infection by a certain virus if the receptor required for attachment and entry is present. The primary attachment receptor may induce a conformational change in the viral envelope protein bound, to induce further interaction with the cell. (Modern Virology) A further interaction may then be required to initiate infection, performed by a coreceptor.The definition of the term coreceptor may sometimes be ambiguous, but generally, it is taken to be the molecule that induces fusion or penetration of a cell. This may be a further determinant of tropism, for example the interaction of HIV-1 Virus entry into a cell is the first step in the life0cycle of a virus; various mechanisms of viral cell enrty are shown in figure 1. The mechanism of entry varies between viruses, but all begin with the binding of a cellular receptor by a viral protein. Binding of a cellular receptor may induce endocytosis or formation of an endosome, the acidic environment of which induces uncoating; this may be dependent upon cellular proteins clathrin or caveolin. Enveloped viruses may require an acidic environment that will induce conformational changes in envelope proteins required to induce membrane fusion, while others, including the measles and HIV viruses, can fuse directly with the plasma membrane at neutral pH. (Baranowski) Fusion at the plasma membrane releases the nucelocapsid into the cytoplasm, where the virus can make its way to the nucleus or begin replication in the cytoplasm. The differences in these entry pathways are due to the nature of the molecular interactions between the vi ral components and target-cell receptors, for example, viruses that mimic the natural ligand of receptors for signalling molecules interefere with their signalling to promote viral entry into the cell and spread of infection. (Bomsell) Conformational changes resulting from the binding of a primary receptor that allow the binding of a fusion receptor are a common mechanism among various types of virus, including influenza and HIV type 1, examples and brief description. Similar to Influenza . Multiple receptors could be coreceptors and act together either to modulate each other or to contribute complementary functions. Alternatively, the receptors might act sequentially. Binding of the virus to the first receptor could cause changes in the virus or host that are necessary before the second receptor can bind (50). For those viruses in fluids with flow, such as blood or respiratory secretions, the initial binding must be able to effect rapid docking of the virus to its host cell. (Haywood) As previously stated, some viruses recognise more than one cellular receptor. The same receptor may also be used by more than one type of virus. (see table 1) Often, these are highly abundant in many tissues, for example, heparan sulfate can serve as a receptor for many viruses, including Human immunodefiecieny virus, Hepatitis C and Dengue Virus and as a co-receptor for Herpesviruses (excluding EBV). (ODonnel) CAR, acts as a receptor for both coxsackie and adenoviruses. (Schneider) Table 1 illustrates the diversity of cell surface molecules which viruses have adapted to recognise. Some viruses use more than one type of molecule as a primary receptor e.g. reoviruses bind to the beta-adrenergic receptor as well as NAN. (Flint) While the presence of certain receptors on host cells is vital to initiate infection, these interactions are not always sufficient to explain all aspects of cell, tissue and species tropism. (Flint)(Haywood, Schneider) Binding of a viral protein to a cell surface receptor does not necessarily mean a productive infection will follow, since a co-receptor may be absent or functional domains of the receptor may be blocked. (Baranowski) Absence of specific cytoplasmic or nuclear molecules may hinder the replication of some viruses, despite their permissivity. However, even a non-productive infection may induce pathogenic effects, for example, binding to specific receptor may induce the secretion of cytokines. (Schneider) A virus generally cannot infect a cell successfully in the absence of its specific receptor, so the distribution around the body of the receptor will act as a restriction on the range of tissues that can be infected and hence on the number of systems in the body where sig ns and symptoms of infection might be experienced. (Flint) In the true sense of the word, Tropism refers to the specific cells a particular virus is able to replicate in, although the use of receptor by a virus is increasingly a valid definition in the field of virology. Additional factors the cause viral tropism will not be considered in the context of this essay, although they may be mentioned briefly where relevant, since the focus of this review is the link between specific receptor usage and virus tropism and pathogenesis. (Kuhmann) The primary topics explored here are the virus-receptor interactions with cells that allow viruses to enter cells and initiate infection and how this relates to the tropism of the virus at a cellular and organismal level. I am to demonstrate how viral attachment and entry is often a complicated multi-step process, sometimes requiring many different cell and virus molecules. The viruses largely used to illustrate these points, Human Immunodeficiency Virus type 1 (HIV-1), Influenza A and Herpes Simplex Virus type 1 (HSV-1) are human viruses of medical significance, but the tropism of these particular viruses in other animals, along with other viruses specific to other animals will be discussed where relevant. The structure and genomic organisation of these viruses is irrelevant and is only discussed where it relates to the glycoproteins that interact with cellular receptors. Viruses of plants, fungi and bacteria are not discussed The presence on the cell surface of a protein that has been identified as the receptor for a given virus may not be sufficient for a productive viral infection, and there may be multiple mechanisms behind such restrictions: functional domains of the receptor may be blocked in some cellular context, additional proteins (or other cofactors) may be needed, or cells may exhibit impediments for completion of the infection cycle, despite an initial successful interaction with a functional receptor. HSV- Demonstrates how viruses may use a large number of viral proteins and receptors to bind and enter specific cells. (Hayashi and Yoon) and how the interactions are a complex multi-step process. Influenza multiple steps. binds many cell types Tropism is dependent on other receptors and interactions. Of the many examples, the interaction of  the human influenza A virus hemagglutinin  with N-acetylneuraminic acid, and the ensuing  conformational alterations involved  in pH-dependent membrane fusion, are one  of the best characterized at the structural  and functional levels (11) (Baranowski 2001)  example of proteolytic cleavage to aid spread and pathogenesis. Conformational change required for fusion HIV A well-documented case of use of multiple receptos is that of HIV-1 viruses and related viruses. Illustrates how a virus may use multiple coreceptors to mediate entry to different types of cells and thus influence the tropism of this virus. Uses some of the same receptors as other viruses (parallels between HIV, HSV and influenza) Multi-step process The interaction of the virion with the attachment receptor leads to the first conformational changes in the envelope proteins. This step enables the interaction with co-receptors, or entry mediators and further conformational changes at the plasma membrane. In enveloped viruses (top), this may deliver the energy for the direct fusion of the viral envelope and cellular membrane. Some enveloped and non-enveloped viruses require the low pH in acidic endosomes to induce this conformational change. Enveloped viruses may require the low pH to induce membrane fusion (centre). These mechanisms lead to the release and possibly uncoating of the virus genome, and the initiation of the virus replication cycle. Role of Viral Receptor Destruction While non-enveloped viruses typically undergo relase through cytolysis. Influenza and HIV-1 Viruses also demonstrate the importance of receptor-destroying activity on the infectivity of some viruses. This is imperative for the efficient release and cell-cell spread of the virus by preventing the glycoproteins on the newly-emerged virus from binding to the host cell receptors. It is also important for preventing superinfection of cells by the same or different viruses utilising the same receptor, which may result in cell death. The efficient budding and release of Influenza A virus from the host cell relies on the removal of Sialic Acid residues by Neuraminidase. In contract, the HIV-1 virus gp120 envelope glycoprotein downregulates the CD4 receptor after infection of monocytes, by stimulating TNF-ÃŽÂ ± production. Other cellular mechanisms contribute to down-modulation of CD4, including the gene product Nef, which causes CD4 internalisation respectively. The precursor of gp120 and gp41, gp160, has also been found to bind CD4 intracellularly in the presence of viral protein Vpu, resulting in retention of CD4 in the Endoplasmic Rectilium. Enveloped particles leave the infected cell inconspicuously  by budding and secretion. Nonenveloped viruses  are usually thought to undergo release through cell lysis,  but some may escape by secretory mechanisms after  budding into membrane bound compartments and then  losing their membrane (Altenburg et al., 1980). Others  may subvert cellular autophagy pathways to gain access  to exocytic organelles (Jackson et al., 2005).  (Marsh)

Modern Man Has Become Enslaved by Time :: Argumentative Persuasive Essays

Modern Man Has Become Enslaved by Time In no characteristic is existing society in the West so sharply distinguished from the earlier societies, whether of Europe or the East, than in its conception of time. To the ancient Chinese or Greek, to the Arab herdsman or Mexican peon of today, time is represented by the cyclic processes of nature, the alternation of day and night, the passage from season to season. The nomads and farmers measured and still measure their day from sunrise to sunset, and their year in terms of seedtime and harvest, of the falling leaf and the ice thawing on the lakes and rivers. The farmer worked according to the elements, the craftsman for as long as he felt it necessary to perfect his product. Time was seen as a process of natural change, and men were not concerned in its exact measurement. For this reason civilizations highly developed in other respects had the most primitive means of measuring time: the hour glass with its trickling sand or dripping water, the sun dial, useless on a dull day, and the candle or lamp whose unburnt remnant of oil or wax indicated the hours. All these devices were approximate and inexact, and were often rendered unreliable by the weather or the personal laziness of the tender. Nowhere in the ancient or mediaeval world were more than a tiny minority of men concerned with time in the terms of mathematical exactitude. Modern, western man, however, lives in a world that runs according to the mechanical and mathematical symbols of clock time. The clock dictates his movements and inhibits his actions. The clock turns time from a process of nature into a commodity that can be measured and bought and sold like soap or sultanas. And because, without some means of exact time keeping, industrial capitalism could never have developed and could not continue to exploit the workers, the clock represents an element of mechanical tyranny in the lives of modern men more potent than any individual exploiter or than any other machine. It is therefore valuable to trace the historical process by which the clock influenced the social development of modern European civilization. It is a frequent circumstance of history that a culture or civilization develops the device that will later be used for its destruction.

Ladron de la mente book report

This book was written by Elias Miguel Munoz, Cuban American writer, who wrote series of books in Spanish language for people, who learn Spanish. He was born in 1954 and is known as editor, teacher and literary critic. He was a talented student as well. Elias Miguel was a man of society, he always thinks about the future generations and makes everything in order to support talented youth. As far as we know, CSU Dominguez Hills received donations of $26  000- this amount was donated by Elias Miguel Munoz and Karen Christian to create the Miguel Gallegos Memorial Scholarship. â€Å"Since I’ve graduated, I’ve had a dream of doing something for Dominguez Hills. I feel so proud of the education I received,† Munoz says. â€Å"And it honors me to be able to give back to the University that did so much for me. The professors in the Foreign Languages Department guided me toward a doctoral degree. My first exposure to literature was at Dominguez Hills, and that led me to writing, which is such a major part of my life now. It all started there.† (http://www.csudh.edu/InvestInUs/PrivateDonors.asp ) After he graduated from CSUDH, Elias Miguel Munoz entered University of California, Irvine (UCI) and received degrees of Master and Doctor in American and Spanish Literature. Moreover, he even began to teach literature at the University of California and everybody there were impressed by a talented student who so brilliantly spoke Mexican and English languages. (http://www.csudh.edu/InvestInUs/PrivateDonors.asp ) Elias Miguel Munoz wrote a lot of books and among them are â€Å"Crazy love† – the book which is a kind of novel where is described an immigration from Cuba to Florida, and which has a lot of information regarding the Cuban-American culture. Among his books are â€Å"Los Viajes de Orlando Cachumbambe (Coleccion Caniqui)†, â€Å"Quia Online Worksbook/Lab Manual t/a Dos Mundos: En Breve†, â€Å"Brand New Memory†, â€Å"En Estas Tierras†, â€Å"Fray Alberto de la madre de dios; Arquitecto (1575-1635), â€Å"Torres y castillos de la Cantabria medieval†, â€Å"Ladron De La Mente†, etc. â€Å"Ladron De La Mente† is of great interest not only for teachers of Spanish language, but also for students and all who start to investigate the mystery of this melodic and amazing language. The chapters of the book are quite short but easy to understand and very interesting. The main heroes of the book behave in such a way that you cannot tear yourself away of the book and you while you are reading, you have the feeling that you are the main hero and you experience all the things that happen there from the very beginning till the end of the story. The story takes place in Madrid (Spain), and the book has a lot of pictures and illustration of the beautiful suburbs of Madrid. It has a glossary at the end of the book, so the students can see unknown words to understand the story more clearly. The subject of the book is dedicated to a young woman and her strange, incomprehensible, mysterious boyfriend and the story is full of mystery, mystics, time travel; it is full of supernatural events, which take place and things one can hardly understand, without explaining it with the simple but strong word â€Å"magic†. Elias Miguel Munoz gives in the book some elements of Spanish history, which in his explanation is of great use for students and allow learning something about Spanish history in an easy and interesting way. During the story takes place and continues, students find out what happens to a thief who steals a thing or something which cannot be named as property, but something else. One of the main characters in the story is Marisol, a young woman. Marisol is a interpreter for one computer company specialized on software, and lives in Madrid with her friend Javier and sister Rocio. Here she is depicted like a beautiful young female with her thought and strong doubts. When the reader investigates the story, he almost associates himself or herself with Marisol, living her life and being the one with her from the beginning till the end of story. The reader connects himself with her from the very beginning. The main hero has a charming character but acts very reasonable and with a bit of irony. For example, she compares herself to Dulcinea – a female character of Servantes’ novel â€Å"Don Quijot† and to another female character in one challenging computer game â€Å"Damsel in Distress† Alfonso – the other character of this interesting story is a charming, tempting and seductive character, who shows his actual face and shows his worth from the bad side gradually. He is able to mask his real â€Å"face† for quite a long period of time and in the book he is charming and seducing Marisol like a real worshipper. Marisol was tremendously tempted by his behavior (http://www.amazon.co.uk/exec/obidos/tg/stores/detail/-/books/0072326174/reviews/026-3948048-6710013 ). Javier and Rocio are the secondary heroes of â€Å"Ladron De La Mente† and they are quite deeply developed by Miguel. Marisol narrates everything what is going on with her and what she is experiencing, in her diary – so the story is written partially in a diary form by her. Still, she leaves a space for other characters to show out their feelings and thoughts. The entire story is penetrated by supernormal events and computer technologies – so the story is very modern (http://www.amazon.co.uk/exec/obidos/tg/stores/detail/-/books/0072326174/reviews/026-3948048-6710013 ). Marisol likes to go to the cinema, to the theater, museums, to experience bright and jolly celebrations – to live a joyous life. Still, she likes museums and paintings there -she says that the work of Guernica influence her very much. She likes also paintings of Dali: â€Å"Aquellos relojes dormidos, flà ¡ccidos,vacà ­os de vida, me parecà ­an el presagio de algo; eran la imagen muerta de un tiempo sin tiempo† – dice Marisol (These weak, empty hours of life, they seemed to me an omen of something, it seemed to be an image, which died from time without time†,- tells Marisol about â€Å"The Persistence of Memory† (Dali, 1931). This work reflects every feeling, the painter wanted to show – feelings of inhabitants of the settlement, and victims of the war. Marisol surfs the internet, she reads science fiction and makes some quite interesting associations and connections between the books of fiction and her own challenging story. In every chapter we find themes of Spanish culture, which are very important in the history of Spain. Works Cited: 1.  Ã‚  Ã‚  Ã‚  Ã‚   Elà ­as Miguel. Ladrà ³n de la mente.

IP and OSI Networking Essays

TCP/IP and OSI Networking Essays TCP/IP and OSI Networking Essay TCP/IP and OSI Networking Essay In this essay I intend to analyse why networking software is divided into layers, and to evaluate the advantages and disadvantages of such a division. I will then go on to analyse what the main differences between the networking protocols known as OSI and TCP/IP are. I will also attempt to analyse what factors led to their successes and failures respectively in terms of their diffusion into the technology sector. However, before we can discuss this, we must first be sure that we are aware of the meanings of terms such as networks, network architecture, protocols, and distributed networks/systems so I will begin by defining these phrases. Essentially, a network is the connection of two or more computers for the purpose of data communication and resource sharing. the formal definition of a network could be given as a number of interconnected devices capable of communicating and sharing each others resources (Bandyo-padhyway, 2000:157) As can be seen from the above quote, networking offers organisations a wealth of benefits. A network enables an organization to centralize its computer system and allows users to access the facilities of a large computer system via desktop computers. (Bandyo-padhyway, 2000:157) It could be said that network architecture is, in theory, a model for the set-up of a network. To help deal with this complexity, network designers have developed general blueprints usually called a network architecture that guide the design and implementation of networks. (Peterson Davie, 1996:29) Protocols, in the networking sense, could be considered as sets of rules or procedures that control how a message is sent from sender to receiver and all the factors involved in this process. A protocol is a set of rules or conventions which govern the way a message is transmitted from the sender to the receiver passing through a number of steps and via a number of network elements. (Bandyo-padhyway, 2000:178) Finally, a distributed network/system is where the tasks to be to be performed are distributed among a number of small PCs that are coordinated by a larger central computer. (Bandyo-padhyway, 2000:173) Having defined the aforementioned basic technological terms, I can now go on to my analysis of the reasons why networking software is divided into layers. The primary reason is that having separate distinctive layers reduces design complexity. By this, I mean having different layers means certain operations and tasks that must be carried out, can be carried out in a simple and organised order, rather than all at the same time. First, it decomposes the problem of building a network into more manageable components. (Peterson Davie, 1996:30) Layering allows for changes to be made at a specific layer, as a result of new ideas/innovation, and will not disrupt the software at other levels. Second, it provides a more modular design. If you decide that you want to add some new service, you may only need to modify the functionality at one layer, re-using the functions provided at all the other layers. (Peterson Davie, 1996:30) This means that it accommodates incremental changes more readily. (www. cs. wpi. edu/~rek/Undergrad_Nets/B03/HTTP_DNS. pdf) Another advantage of layering is that details of how the lower level services are implemented are shielded from the higher levels, allowing the higher levels to function more efficiently. This can be seen, from a more technological point of view, in the following quote. Many times there are multiple abstractions provided at any given level of the system, each providing a different service to the higher layers but building on the same low-level abstractions. (Peterson Davie, 1996:30) A final advantage of layering is that as a result of the different types of layers, making it so different types of translations can take place; different types of hardware are enabled to communicate. Having looked at the advantages of layering, I will now spend some time discussing its disadvantages. Some functions (like FDDI station management) really need to access and operate at multiple layers. (courses. cs. vt. edu/~cs5516/spring03/ slides/introduction_6. pdf) As the above quote displays, one disadvantage is since the software is split up into layers, functions will operate at one level at a time, where as some functions have the necessity to operate at several layers. Poorly conceived layers can lead to awkward and complex interfaces. (courses. cs. vt. edu/~cs5516/spring03/ slides/introduction_6. pdf) This quote shows us that unless a large amount of thought and work goes into each individual layer, then a very bad and hard-to-use interface can be the end-result. Another disadvantage is if new design for a layer is done, an old layer may become inappropriate or unsuitable given the properties of the new layer. (courses. cs. vt. edu/~cs5516/spring03/ slides/introduction_6. pdf) A final disadvantage of layering is something known as information hiding, this may take place and this can lead to inefficient implementations. (www-inst. eecs. berkeley. edu/~cs268/ sp03/notes/Lecture2. pdf) I have discussed why networking software is divided into layers as well as evaluating both the advantages and disadvantages of layering. I now intend to introduce the first of the aforementioned protocols Open Systems Interconnection (OSI), before then introducing the second. A number of different types of distributed systems were being developed in the 1970s and as a result, a range of standards had to be introduced. (Halsall, 1996:11) An organisation called the International Standards Organizaton (ISO) created the ISO Reference Model for OSI. The ISO was a body founded in 1945 to coordinate international standards for a wide range of industries. (The Internet in the Arena of International Standards) Below is a diagram of the OSI protocol, taken from Peterson and Davie. As can be seen, the OSI protocol has seven layers. The application layer provides the user interface to a range of networkwide distributed information services. The presentation layer is associated with the representation of data during transfer between two communicating application processes. The session layers job is to set up a communication channel between two communicating application layer protocol entities during a network transaction. The network layer is responsible for establishing a networkwide connection between two transport layer protocol entities. The link layers job is to build on the physical connection provided by the network to provide the network layer with a reliable information transfer facility. Finally, the physical layer is associated with the physical and electrical interfaces between the user equipment and the network terminating equipment. (Halsall, 1996:16, 17, 18) I will now introduce the second networking protocol so that we have a good understanding of them both, before analysing their differences. The second protocol is called Transmission Control Protocol/Internet Protocol (TCP/IP). TCP/IP was developed by the US Department of Defence (DOD) research project to connect a number of different networks designed by different vendors into a network of networks. (www. yale. edu/pclt/COMM/TCPIP. HTM) The idea behind the DODs thinking was that in the Cold War, if the right designated place was bombed successfully, then the whole countries network communication facilities would become inoperable. This was obviously be a bad thing and so the DOD wanted to develop a standard that would connect all the networks together to prevent this from happening. Below is the model of the TCP/IP protocol, taken from (www-staff. t. uts. edu. au/~sean/DSP. dir/dsp00s. dir/lect1. dir/sld014. htm) As can be seen, the TCP/IP protocol has only four layers. The application layer handles high level protocols. The transport layer deals with quality-of-service issues. The internet layer determines the path to forward packets of data. The network layer is concerned with all of the issues that an IP packet requires to make a physical link. (www-staff. it. uts. edu. au/~sean/DSP. dir/dsp00s. dir/lect1. dir/sld014. htm) Now that I have briefly introduced both of the protocols, I will now move on to my analysis of their main differences. A difference between the two protocols in terms of their establishers is that OSI was orally established by Telcos, a telecommunications company and had a large connected emphasis linked to it. TCP/IP came more from a computing background with a large connectionless emphasis associated with it. Another difference that should be noted is that the two models have opposing approaches. The OSI model has a top-down approach meaning the processes that take place within the layers start at the top of the model and work their way down to the bottom. The TCP/IP model has a bottom-up approach meaning the processes taking place within the layers begin at the bottom of the model and move upwards. As can be seen from the models, the visible difference is the number of layers present within each. The OSI protocol has application, presentation, session, transport, network, data link, and physical layers. Where as the TCP/IP protocol has only application, transport, internet and network layers. Even though some of the layers have different names, they essentially do the same thing. However, the presentation and session layers that are in the OSI model are not present in the TCP/IP model. This makes the two protocols technologically different. First there were the technical differences, chief among them that OSI had a more complicated and compartmentalised design. (Lyon Hafner, 2003:246) The above quote points out how the OSI design was considered to be very large and complex where as the TCP/IP design was far more simplistic and smaller. On the OSI side stood an entrenched bureaucracy, with a strong we-know best attitude, patronizing and occasionally contemptuous. There was a certain attitude among certain parts of the OSI community whose message was, Time to toll up your toy academic network,' recalled one ardent TCP/IP devotee (Lyon Hafner, 2003:247) We can see from the above quote that OSI was regarded as a potential official standard with a considerable amount of bureaucratic support, as opposed to TCP/IP, which was seen by some as a toy network for the academic world only, and would never have any real chance of becoming an official standard networking protocol. The reason being was that the OSI was created by the ISO, and the ISO had long been responsible for creating international standards for a variety of industries, as the following quote displays. Since the 1940s, ISO had specified worldwide standards for things ranging from wine-tasting glasses to credit cards to photographic film to computers. (Lyon Hafner, 2003:246) As a result of this official standardization reputation that ISO had created for themselves, OSI was backed by several governments, led by Europe, and was thought to be meeting the needs of the whole world. Another difference between TCP/IP and OSI, was that TCP/IP had actually been implemented where as the only thing OSI had to offer was the design model for the protocol, as the following quote shows. And it was a design, never tried. As far as the Internet crowd was concerned, they had actually implemented TCP/IP several times over, whereas the OSI model had never been put to the test of daily use, and trial and error. (Lyon Hafner, 2003:247) An extremely large difference between the two protocols is in relation to their impacts on the networking world respectively. OSI failed to become to the official international networking standard that it was predicted to be. TCP/IP, contrary to what many had anticipated, was a huge success within the networking protocol world and is used across the world today. However, one must ask, what factors led to this outcome? One factor was that one key TCP/IP developer, Bill Joy, decided that TCP/IP when bought was to come with free networking software, which was based on Unix. As can be imagined, the fact that one received free Unix networking software when buying TCP/IP with no extra charge dramatically helped push TCP/IP further than OSI. The first Sun machines were shipped with the Berkeley version of Unix, complete with TCP/IP. Berkeley Unix with TCP/IP would be crucial to the growth of the Internet. When Sun included network software as part of every machine it sold and didnt charge separately for it, networking exploded. (Lyon Hafner, 2003:250) To clarify, Sun was the name of the computer company that Joy joined as the Unix expert. Another factor that led to TCP/IPs success was the fact that ARPANET decided to switch over to it on January 1, 1983. ARPANET was the resulting internetwork developed when computer networks associated with a large number of universities and other research establishments were linked and it was in large usage. (Halsall, 1996:19) As a result, TCP/IP was pushed even further ahead when ARPANET switched its protocols from Network Control Protocol to TCP/IP as this meant only machines running the new protocols could communicate over the network. Lyon Hafner, 2003:248) Dennis Jennings tells us of a factor that largely contributed to the failure of OSI when it was announced by the manager of a company called ICL at a review meeting that the output of the OSI research would not be in the interests of ICL. The Commission then told ICL that they could do what ever they like. This meant that where would be no available implementation opportunities for OSI once the research had been completed, and Jennings feels that this made it so that OSI had absolutely no chance of success. So what ever the merits of having a set of open OSI protocols, it was a serious attempt to provide an available solution, and the Commission allowed the project to throw it away. OSI died at that meeting. Without available implementations, it had no hope. (Randall, 1997:218) Another thing worth saying is that because the Internet boomed and became increasingly popular, and TCP/IPs design had a layer devoted to the Internet, TCP/IPs popularity was again increased further as a result of the Internets rapid growth. One could argue that OSI, being a protocol that did not include a layer for the Internet in its design, was over-run by the Internets growth. A final factor I would like to mention is the belief that a main reason OSI was not a success was because it got too preoccupied with the standards process and attempting to approve too many that it became caught up with them. It is seen by some that this caused it to fail as it distracted OSI from the one single standard that it was supposed to produce, the following quote shows this. But ISOs plan to make the OSI protocols a single standard for all computer users was defeated by ISOs own practice of approving multiple standards. (International Standards). To conclude, the concept of layering within networking software is in usage as it provides many advantages in terms of the softwares performance itself. Although, it does also pose some disadvantages, I feel they are small in number are not strong enough to outweigh the advantages. My analysis of the two networking protocols, OSI and TCP/IP, shows their main differences in terms of technical as well as social factors. I have also discussed the two differing impacts the protocols had in the world of networking and have attempted to explain why by looking at important factors associated with their diffusions. From my analysis, one can see that OSI was mostly a failure, as opposed to TCP/IP which won the protocols war and is in large international usage today.

Within almost all eukaryotic cells the endoplasmic reticulum, Golgi Essay

Within almost all eukaryotic cells the endoplasmic reticulum, Golgi complex and endosomes can be considered as a system, cooperating to deliver secerted material to the cell surface - Essay Example Why is it that all these are considered as a system? This is because it has a set of membranes forming a single functional and developmental unit that are either connected directly or exchanging materials via a vesicle transport. Nonetheless, it is vital to note that the system does not include the chloroplasts and mitochondria membranes (Cooper, 2000). This paper seeks to discuss the statement that states, â€Å"Within almost all eukaryotic cells the endoplasmic reticulum, Golgi complex and endosomes can be considered as a system, cooperating to deliver secreted material to the cell surface.† To understand and discuss the above statement in greater length, one must understand the mechanisms and definitions of various terms. Some of these terms include: Golgi apparatus, eukaryotic cells, endosomes among others. Generally, the nuclear or atomic envelope is a layer with two lipid bilayers that envelops the substance of the core. The endoplasmic reticulum (ER) is a blend and transport organelle that extends into the cytoplasm in both animal and plant cells (Cooper, 2000). The Golgi apparatus refers to an arrangement of numerous partitions where particles are bundled for conveyance to other cell segments or emission from the cell. Additionally, vacuoles, which are present in both animal cells, though it greatly manifests in plants, are in charge of keeping up the shape and structure of the cell. In addition, they put away waste items. A vesicle is a little, membrane-encased sac that acts as a storage and transportation agent for substances. The plasma membrane, likewise alluded to as the cell layer, is a defensive hindrance that controls what goes into and goes out of the cell. There is additionally an organelle known as the spitzenkorper that is just present in parasites and is associated with the development of the hyphae tip (Cooper, 2000). In prokaryotes, endomembrane is
