Production and Market behaviour - Essay Example se classical scholars continue to influence contemporary scholars as they attempt to discern the major factors influencing productions and market patterns to enhance efficiency and best economic systems. Our study of production and market behavior will therefore be based principally on neoclassical and institutionalism models that have existed since the last century and will explore the new-institutionalism impact on the theme as well as the recent trends in fair trade and corporate social responsibility (CSR). Neoclassical theories supported by Keynesian economics are the dominant approaches prevalent in mainstream economic theories from the mid twentieth century (Clark, 1998). The theory however can be traced to 19th century after the Industrial Revolution as capitalism ignited intellectual ideas among all disciplines. One prominent neoclassical analyst was William Stanley Jevons and his marginal utility theory of value in 1862. Neoclassical theories are mainly based on individual or microeconomics by exploiting utility as explained in the rational choice theory (Ehrenberg, 1997). Neoclassical economist Marshall’s treatise Principles of Economics (1890) described price disparities in terms of the intersection of supply and demand curves. He also introduced diverse ‘market periods’ as follows: Short period – business faculty is specified, the level of yield, service, assets, and value oscillate to link marginal cost and marginal revenue, where returns are maximized. Economic rents only survive for short duration for unchanging aspects, and the velocity of earnings is not contrasted across segments. The neoclassical model has also engendered the First Theorem of Welfare Economics that emphasis that indirect marginal utility for all the market players is similar. This also depicted in a Pareto-efficient condition that states any enhancement in the utility of one user might jeopardize another’s value. The organizations operating in such a scenario do

Sentences structured carefully are disappearing on the internet. As users are getting acquainted of each other’s vocabulary, proper grammar is deteriorating. He recognizes that there is a tendency of feeding customized â€Å"Internet Speak† that is developing among those on the internet. The grammar on formal websites still follows the traditional laid out rules, emails are starting to see a condensed version and instant messaging is even worse. The reason for this is rooted in the belief that expertise is not a necessity and is a waste of money and time. He cites the example of existence of many civilizations for centuries. Also proper use of grammar does not solve any problem as many cannot read at a collegiate level. The author then goes on to sarcastically criticize such form of writing as saying that he wonders how such messages are legible (Wertheimer, 2002). He says that on examining any message, even be it from a CEO, many grammatical errors can be found. He points out the reason why such messages have been working. In the last few years as the use of internet has increased, users have not only tolerated such abuse of grammar but encouraged such styles in order reply to messages as soon as they receive it. Need for speed is the reason behind this development. Punctuating and capitalizing is just a loss of time. Hence the need to be fast has lead to this condensing of sentencing and in turn grammar. One of the examples that author gives is the use of â€Å"g2g† which means â€Å"got to go†. The author goes on to explain that languages demand perfectionism by being grammatically correct but this is not the case on the internet. A communication’s effectiveness is dependent on the speed of the communication. Longer the sentence is slower the process and

Comparison between Hitler and Stalin Essay Example for Free

Comparison between Hitler and Stalin Essay The complexity of Stalins character and his role becomes most apparent when a comparison is attempted between him and Hitler. Their similarities are numerous and striking. Each of them suppressed opposition without mercy or scruple. Each built up the machine of a totalitarian state and subjected his people to its constant, relentless pressure. Each tried to remould the mind of his nation to a single pattern from which any undesirable impulse or influence was excluded. Each established himself as an unchallengeable master ruling his country in accordance with a rigid Fuhrerprinzip. Here the similarities cease and the differences begin. Not in a single field has Hitler made the German nation advance beyond the point it had reached before he took power. In most fields he has thrown it back far behind; terribly far behind. The Germany he took over in 1933 was, despite economic depression and social strains and stresses, a wealthy and flourishing country. Its industry was the most efficient on the continent. Its social services were the most modern that any European nation had had. Its universities were great centres of learning, priding themselves on famous men of science. The better part of the German youth was serious, alert and idealistic. The German theatre was the object of the highest admiration and of imitation. The best German newspapers were the most intelligent and the best informed of the continental press. The Germany that Hitler left behind was impoverished and reduced to savagery. We are not speaking about the effects of Germanys defeat, but about the state of the nation, regardless of defeat. The material apparatus of production which the country possessed under Hitler was, apart from special armament plants, not essentially greater than that which it had possessed before. Its social services were half destroyed. Its universities became drilling grounds-for a generation of horrible brutes. Its famous men of science were compelled either to emigrate or to accept the guidance of SS men and to learn racialist gibberish. Its medical men were turned into specialists on the racial purity of blood and into the assassins of those whose blood was deemed impure. In the sanctuary of national philosophy Alfred Rosenberg sequestrated for himself the niche that used to be occupied by Immanuel Kant. Twelve years of education by a nazified press, radio, cinema, and theatre left the collective mind of Germany stultified and ruined. These terrible losses were not redeemed by a single positive acquisition or by a single new idea, unless one chooses to regard as new the idea that one nation or race is entitled to dominate or exterminate the others. Nor was the social structure of the nation essentially changed by national socialism. When the Nazi facade was blown away, the structure that revealed itself to the eyes of the world was the same as it had been before Hitler, with its big industrialists, its Krupps and Thyssens, its Junkers, its.middle classes, its Grossbauers, its farm labourers, and its industrial workers. Sociologically, although not politically, the Germany of 1945 was still the Germany of the Hohenzollerns, only thrown into terrible disorder and confusion by a tragically purposeless riot. What a contrast, after all, Stalinist Russia presents. The nation over which Stalin took power might, apart from small groups of educated people and advanced workers, rightly be called a nation of savages. This is not meant to cast any reflection on the Russian national character Russias backward, Asiatic condition has been her tragedy, not her fault. Stalin undertook, to quote a famous saying, to drive barbarism out of Russia by barbarous means. Because of the nature of the means he employed, much of the barbarism thrown out of Russian life has crept back into it. The nation has, nevertheless, advanced far in most fields of its existence. Its material apparatus of production, which about 1930 was still inferior to that of any medium-sized European nation, has so greatly and so rapidly expanded that Russia is now the first industrial power in Europe and the second in the world. Within little more than one decade the number of her cities and towns doubled; and her urban population gr ew by thirty millions. The number of schools of all grades has very impressively multiplied. The whole nation has been sent to school. Its mind has been so awakened that it can hardly be put back to sleep again. Its avidity for knowledge, for the sciences and the arts, has been stimulated by Stalins government to the point where it has become insatiable and embarrassing. It should be remarked that, although Stalin has kept Russia isolated from the contemporary influences of the west, he has encouraged and fostered every interest in what he calls the cultural heritage of the west. Perhaps in no country have the young been imbued with so great a respect and love for the classical literature and art of other nations as in Russia. This is one of the important differences between the educational methods of nazism and Stalinism. Another is that Stalin has not, like Hitler, forbidden the new generation to read and study the classics of their own literature whose ideological outlook does not accord with his. While tyrannizing the living poets, novelists, historians, painters, and even composers, he has displayed, on the whole, a strange pietism for the dead ones. The works of Pushkin, Gogol, Tolstoy, Chekhov, Belinsky, and many others, whose satire and criticism of past tyranny have only too often a bearing on the present, have been literally pressed into the hands of youth in millions of copies. No Russian Lessing or Heine has been burned at an auto-da-fà ¯Ã‚ ¿Ã‚ ½. Nor can the fact be ignored that the ideal inherent in Stalinism, one to which Stalin has given a grossly distorted expression, is not domination of man by man, or nation by nation, or race by race, but their fundamental equality. Even the proletarian dictatorship is presented as a mere transition to a classless society; and it is the community of the free and the equal, and not the dictatorship, that has remained the inspiration. Thus, there have been many positive, valuable elements in the educational influence of Stalinism, elements that are in the long run likely to turn against its worse features. Finally, the whole structure of Russian society has undergone a change so profound and so many-sided that it cannot really be reversed. It is possible to imagine a violent reaction of the Russian people itself against the state of siege in which it has been living so long. It is even possible to imagine something like a political restoration. But it is certain that even such a restoration would touch merely the surface of Russian society and that it would demonstrate its impotence vis-à ¯Ã‚ ¿Ã‚ ½-vis the work done by the revolution even more thoroughly than the Stuart and the Bourbon restorations had done. For of Stalinist Russia it is even truer than of any other revolutionary nation that twenty years have done the work of twenty generations. For all these reasons Stalin cannot be classed with Hitler, among the tyrants whose record is one of absolute worthlessness and futility. Hitler was the leader of a sterile counter-revolution, while Stalin has been both the leader and the exploiter of a tragic, self-contradictory but creative revolution. Like Cromwell, Robespierre and Napoleon he started as the servant of an insurgent people and made himself its master. Like Cromwell he embodies the continuity of the revolution through all its phases and metamorphoses, although his role was less prominent in the first phase. Like Robespierre he has bled white his own party; and like Napoleon he has built his half-conservative and half-revolutionary empire and carried revolution beyond the frontiers of his country. The better part of Stalins work is as certain to outlast Stalin himself as the better parts of the work of Cromwell and Napoleon have outlasted them. But in order to save it for the future and to give to it its full value, history may yet have to cleanse and reshape Stalins work as sternly as it once cleansed and reshaped the work of the English revolution after Cromwell and of the French after Napoleon. From Stalin, A Political Biography, I. Deutscher, Oxford University Press, 1949.,

Analysis of Weinbergers Concepts of Cyberwarfare

Analysis of Weinbergers Concepts of Cyberwarfare In June 2010, analysts from the antivirus software company VirusBlokAda examined a computer in Iran due to suspicion of malware activity. Lurking inside the machine was a computer worm known as Stuxnet. Stuxnet possessed an array of abilities, among them was the ability to target the software that controls pumps, valves, generators and other industrial machines (Weinberger, 2011). Unlike other viruses that use forged security clearances to gain access into systems, Stuxnet took advantage of two digital certificates of authenticity stolen from respected companies (Weinberger, 2011). Furthermore, it exploited four different zero day vulnerabilities' which are security gaps that system creators were unaware of (Weinberger, 2011). According to Liam O Murchu, chief of security response of Symantec, once Stuxnet infected a system, the crucial parts of its executable code would become active only if that machine was also running Siemens Step 7, one of the many supervisory control and data (SCADA) systems used to manage industrial processes (Weinberger, 2011). Symantec also discovered that the majority of infections were in Iran and that the infections seemed to have been appearing there in waves since 2009 (Weinberger, 2011). Further investigation performed by Ralph Langner, a control-system security consultant, resulted in evidence that Stuxnet had been deliberately directed against Iran, the most likely target being Irans Nuclear Enrichment Facility in Natanz. (Weinberger, 2011). According to Langner, Stuxnet was designed to alter the speed of the delicate centrifuges which separated Irans rare but fissionable isotope uranium -235 from the heavier uranium -238 (Weinberger, 2011). Improper alteration of the cent rifuges could result in them spinning out of control and breaking. Although the Iranian Government refuses to admit that Stuxnet was responsible for the destruction of many centrifuges at Natanz, the results from Langner and others is credited by reports from the International Atomic Energy Agency. The IAEA documented a precipitous drop in the number of operating centrifuges in 2009, the year that many observers think Stuxnet infected computers in Iran (Weinberger, 2011). There is no evidence beyond rumor that Israel or the US Government may have been behind the attack. Symantec notes that a name embedded in Stuxnets code, Myrtus, could be a reference to a biblical story about a planned massacre of Jews in Persia (Weinberger, 2011). Moreover, Langner believes that the U.S. Government could have been behind the attack considering they possess both the required expertise in cyber warfare and a long-standing goal of thwarting Irans nuclear ambitions (Weinberger, 2011). Irrespective of Stuxnets creator, the main growing fear is who will redesign it. Stuxnet was the first weapon created entirely out of code and proved that groups or nations could launch a cyber-attack against a societys vital infrastructures (Weinberger, 2011). Many of the investigators that studied Stuxnet concluded that it essentially laid out a blueprint for future attackers to learn from and perhaps improve (Weinberger, 2011). Stuxnet opened a new era of warfare and with its code available online for anyone to study and improve, it has computer scientists like Yuval Elovici concerned that the next wave of cyber-attacks would be much stronger than the impact of setting several atomic bombs on major cities (Weinberger, 2011). In IS THIS THE START OF CYBERWARFARE? Sharon Weinberger questions whether or not Stuxnet started a new era of warfare. One might find that Weinbergers use of supporting evidence from many credible sources imposes a compelling answer to an interesting topic of study. Weinberger emphasizes the inferred answer is indeed yes, Stuxnet introduced a new era of warfare. Statements such as Stuxnet is the harbinger of a new generation of cyber threats and that it provided chilling proof that groups or nations could launch a cyber-attack against a societys vital infrastructures are well validated by the many investigators that studied it (Weinberger, 2011). Overall, one would appreciate Weinbergers supportive writing style and the information she presented in this article. Weinberger was heavily resourceful and made certain that every point she made was reinforced by credible supporting evidence. Furthermore, one would relish how she tailored her article to a broader audience. Easy and straightforward for a non tech-savvy individual to understand, and yet interesting to captivate the minds of those that are tech-savvy, she capitalized on the statements made from some of the most respected cyber security experts in the world. As a student who often finds himself being the rescue to many of his friends or familys infected PCs, choosing Stuxnet as my topic of study seemed like the obvious choice. I have always been very interested in computer malware since the day my laptop first got infected. I was bombarded with annoying ads telling me that I had a virus on board and that I needed to type in my credit card number to purchase antivirus protection. Although very annoying, it had me asking myself many questions like how did this happen, isnt Windows secure and best of all how do I delete my browsing history. Since then, I have always had a keen interest in malware and have developed a hobby of testing the capabilities of different antivirus programs in VMware Player. I find many things interesting about Stuxnet but the thing I find most interesting is how it spread. Although Stuxnet possessed the ability to spread through networks, it couldnt infect industrial control systems via the internet since a majority of them lack internet connectivity to protect them from malware and hostile takeover. (Weinberger, 2011). To get past this obstacle, Stuxnet had the ability to covertly install itself on a USB drive (Weinberger, 2011). Like a biological virus, Stuxnet used humans (plant operators specifically) as its host of transmission. If one careless plant operator were to plug in an infected USB flash drive into a control-system computer, Stuxnet would begin its destruction.   Weinberger, S. (2011, June 9). IS THIS THE START OF CYBERWARFARE? Nature, 142-145. Retrieved from http://search.proquest.com.uproxy.library.dc-uoit.ca/docview/872363390?accountid=14694 Last years Stuxnet virus attack represented a new kind of threat to critical infrastructure. Just over a year ago, a computer in Iran started repeatedly rebooting itself, seemingly without reason. Suspecting some kind of malicious software (malware), analysts at VirusBlokAda, an antivirus-software company in Minsk, examined the misbehaving machine over the Internet, and soon found that they were right. Disturbingly so: the code they extracted from the Iranian machine proved to be a previously unknown computer virus of unprecedented size and complexity. On 17 June 2010, VirusBlokAda issued a worldwide alert that set off an international race to track down what came to be known as Stuxnet: the most sophisticated computer malware yet found and the harbinger of a new generation of cyberthreats. Unlike conventional malware, which does its damage only in the virtual world of computers and networks, Stuxnet would turn out to target the software that controls pumps, valves, generators and other industrial machines. It was the first time wed analysed a threat that could cause real-world damage, that could actually cause some machine to break, that might be able to cause an explosion, says Liam O Murchu, chief of security response for the worlds largest computer-security firm, Symantec in Mountain View, California. Stuxnet provided chilling proof that groups or nations could launch a cyberattack against a societys vital infrastructures for water and energy. We are probably just now entering the era of the cyber arms race, says Mikko Hypponen, chief research officer for F-Secure, an antivirus company based in Helsinki. Worse yet, the Stuxnet episode has highlighted just how inadequate are societys current defences and how glaring is the gap in cybersecurity science. Computer-security firms are competitive in the marketplace, but they generally respond to a threat such as Stuxnet with close collaboration behind the scenes. Soon after Virus- BlokAdas alert, for example, Kaspersky Lab in Moscow was working with Microsoft in Redmond, Washington, to hunt down the vulnerabilities that the virus was exploiting in the Windows operating system. (It was Microsoft that coined the name Stuxnet, after one of the files hidden in its code. Technically, Stuxnet was a worm, a type of malware that can operate on its own without needing another program to infect. But even experts often call it a virus, which has become the generic term for self-replicating malware.) One of the most ambitious and comprehensive responses was led by Symantec, which kept O Murchu and his worldwide team of experts working on Stuxnet around the clock for three months. One major centre of operations was Symantecs malware lab in Culver City, California, which operates like the digital equivalent of a top-level biological containment facility. A sign on the door warns visitors to leave computers, USB flash drives and smart phones outside: any electronic device that passes through that door, even by mistake, will stay there. Inside the lab, the team began by dropping Stuxnet into a simulated networking environment so that they could safely watch what it did. The sheer size of the virus was staggering: some 15,000 lines of code, representing an estimated 10,000 person hours in software development. Compared with any other virus ever seen, says O Murchu, its a huge amount of code. Equally striking was the sophistication of that code. Stuxnet took advantage of two digital certificates of authenticity stolen from respected companies, and exploited four different zero day vulnerabilities previously unidentified security holes in Windows that were wide open for hackers to use. Then there was the viruss behaviour. Very quickly we realized that it was doing something very unusual, recalls O Murchu. Most notably, Stuxnet was trying to talk to the programmable logic controllers (PLCs) that are used to direct industrial machinery. Stuxnet was very selective, however: although the virus could spread to almost any machine running Windows, the crucial parts of its executable code would become active only if that machine was also running Siemens Step7, one of the many supervisory control and data acquisition (SCADA) systems used to manage industrial processes. Many industrial control systems are never connected to the Internet, precisely to protect them from malware and hostile takeover. That led to another aspect of Stuxnets sophistication. Like most other malware, it could spread over a network. But it could also covertly install itself on a USB drive. So all it would take was one operator unknowingly plugging an infected memory stick into a control-system computer, and the virus could explode into action. 6.1 Murky Motives It still wasnt clear what Stuxnet was supposed to do to the Siemens software. The Symantec team got a clue when it realized that the virus was gathering information about the host computers it had infected, and sending the data back to servers in Malaysia and Denmark presumably to give the unknown perpetrators a way to update the Stuxnet virus covertly. Identifying the command and control servers didnt allow Symantec to identify the perpetrators, but they were able to convince the Internet service providers to cut off the perpetrators access, rerouting the traffic from the infected computers back to Symantec so that they could eavesdrop. By watching where the traffic to the servers was coming from, O Murchu says, we were able to see that the majority of infections were in Iran at least 60% of them. In fact, the infections seemed to have been appearing there in waves since 2009. The obvious inference was that the virus had deliberately been directed against Iran, for reasons as yet unknown. But the Symantec investigators couldnt go much further by themselves. They were extremely knowledgeable about computers and networking, but like most malware-protection teams, they had little or no expertise in PLCs or SCADA systems. At some point in their analysis they just couldnt make any more sense out of what the purpose of this thing was, because they were not able to experiment with the virus in such a lab environment, says Ralph Langner, a control-system security consultant in Hamburg, Germany. Langner independently took it upon himself to fill that gap. Over the summer, he and his team began running Stuxnet in a lab environment equipped with Siemens software and industrial control systems, and watching how the virus interacted with PLCs. We began to see very strange and funny results immediately, and I mean by that within the first day of our lab experiment, he says. Those PLC results allowed Langner to infer that Stuxnet was a directed attack, seeking out specific software and hardware. In mid-September 2010, he announced on his blog that the evidence supported the suspicion that Stuxnet had been deliberately directed against Iran. The most likely target, he then believed, was the Bushehr nuclear power plant. 6.2 Industrial Sabotoge Speculative though Langners statements were, the news media quickly picked up on them and spread the word of a targeted cyberweapon. Over the next few months, however, as Langner and others continued to work with the code, the evidence began to point away from Bushehr and towards a uranium-enrichment facility in Natanz, where thousands of centrifuges were separating the rare but fissionable isotope uranium-235 from the heavier uranium-238. Many Western nations believe that this enrichment effort, which ostensibly provides fuel for nuclear power stations, is actually aimed at producing a nuclear weapon. The malware code, according to Langner and others, was designed to alter the speed of the delicate centrifuges, essentially causing the machines to spin out of control and break. That interpretation is given credence by reports from the International Atomic Energy Agency (IAEA) in Vienna, which document a precipitous drop in the number of operating centrifuges in 2009, the year that many observers think Stuxnet first infected computers in Iran. True, the evidence is circumstantial at best. We dont know what those machines were doing when they werent in operation, cautions Ivanka Barszashka, a Bulgarian physicist who studied Iranian centrifuge performance while she was working with the Federation of American Scientists in Washington DC. We dont know if they were actually broken or if they were just sitting there. Moreover, the Iranian government has officially denied that Stuxnet destroyed large numbers of centrifuges at Natanz, although it does acknowledge that the infection is widespread in the country. And IAEA inspection reports from late 2010 make it clear that any damage was at most a temporary setback: Irans enrichment capacity is higher than ever. However, if Natanz was the target, that does suggest an answer to the mystery of who created Stuxnet, and why. Given the knowledge required including expertise in malware, industrial security and the specific types and configurations of the industrial equipment being targeted most Stuxnet investigators concluded early on that the perpetrators were backed by a government. Governments have tried to sabotage foreign nuclear programmes before, says Olli Heinonen, a senior fellow at the Belfer Center for Science and International Affairs at Harvard University in Cambridge, Massachusetts, and former deputy director-general of the IAEA. In the 1980s and 1990s, for example, Western governments orchestrated a campaign to inject faulty parts into the network that Pakistan used to supply nuclear technology to countries such as Iran and North Korea. Intelligence agencies, including the US Central Intelligence Agency, have also made other attempts to sell flawed nuclear designs to would-be proliferators. Stuxnet, says Heinonen, is another way to do the same thing. Langner argues that the government behind Stuxnet is that of the United States, which has both the required expertise in cyberwarfare and a long-standing goal of thwarting Irans nuclear ambitions. Throughout the summer of 2010, while Langner, Symantec and all the other investigators were vigorously trading ideas and information about Stuxnet, the US Department of Homeland Security maintained a puzzling silence, even though it operates Computer Emergency Readiness Teams (CERTs) created specifically to address cyberthreats. True, the CERT at the Idaho National Laboratory outside Idaho Falls, which operates one of the worlds most sophisticated testbeds for industrial control systems, did issue a series of alerts. But the first, on 20 July 2010, came more than a month after the initial warning from Belarus and contained nothing new. Later alerts followed the same pattern: too little, too late. A delayed clipping service, said Dale Peterson, founder of Digital Bond, a SCADA security firm in Sunrise, Florida, on his blog. There is no way that they could have missed this problem, or that this is all a misunderstanding. Thats just not possible, says Langner, who believes that the Idaho labs anaemic response was deliberate, intended to cover up the fact that Stuxnet had been created there. But even Langner has to admit that the evidence against the United States is purely circumstantial. (The US government itself will neither confirm nor deny the allegation, as is its practice for any discussion of covert activity.) And the evidence against the other frequently mentioned suspect, Israel, is even more so. Symantec, for example, points out that a name embedded in Stuxnets code, Myrtus, could be a reference to a biblical story about a planned massacre of Jews in Persia. But other investigators say that such claims are beyond tenuous. There are no facts about Israel, declares Jeffrey Carr, founder and chief executive of Taia Global, a cybersecurity consulting company in Tysons Corner, Virginia. 6.3 The Aftermath The who? may never be discovered. Active investigation of Stuxnet effectively came to an end in February 2011, when Symantec posted a final update to its definitive report on the virus, including key details about its execution, lines of attack and spread over time. Microsoft had long since patched the security holes that Stuxnet exploited, and all the antivirus companies had updated their customers digital immune systems with the ability to recognize and shut down Stuxnet on sight. New infections are now rare although they do still occur, and it will take years before all the computers with access to Siemens controllers are patched. If Stuxnet itself has ceased to be a serious threat, however, cybersecurity experts continue to worry about the larger vulnerabilities that it exposed. Stuxnet essentially laid out a blueprint for future attackers to learn from and perhaps improve, say many of the investigators who have studied it. In a way, you did open the Pandoras box by launching this attack, says Langner of his suspicions about the United States. And it might turn back to you guys eventually. Cybersecurity experts are ill-prepared for the threat, in part because they lack ties to the people who understand industrial control systems. Weve got actually two very different worlds that traditionally have not communicated all that much, says Eric Byres, co-founder and chief technology officer of Tofino Industrial Security in Lantzville, Canada. He applauds Symantec, Langner and others for reaching across that divide. But the effort required to make those connections substantially delayed the investigation. The divide extends into university computer-science departments, say Byres, himself an ex-academic. Researchers tend to look at industrial-control security as a technical problem, rather than an issue requiring serious scientific attention, he says. So when graduate students express interest in looking at, say, cryptography and industrial controls, they are told that the subject is not mathematically challenging enough for a dissertation project. Im not aware of any academic researchers who have invested significantly in the study of Stuxnet, agrees Andrew Ginter, director of industrial security for the North American group of Waterfall Security Solutions, based in Tel Aviv, Israel. Almost the only researchers doing that kind of work are in industrial or government settings among them a team at the Idaho National Laboratory working on a next-generation system called Sophia, which tries to protect industrial control systems against Stuxnet-like threats by detecting anomalies in the network. One barrier for academics working on cybersecurity is access to the malware that they must protect against. That was not such a problem for Stuxnet itself, because its code was posted on the web shortly after it was first identified. But in general, the careful safeguards that Symantec and other companies put in place in secure labs to protect the escape of malware may also inadvertently be a barrier for researchers who need to study them. If youre doing research into biological agents, its limited groups that have them and they are largely unwilling to share; the same holds true for malware, says Anup Ghosh, chief scientist at the Center for Secure Information Systems at George Mason University in Fairfax, Virginia. To advance the field, researchers need access to good data sets, says Ghosh, who was once a programme manager at the US Defense Advanced Research Projects Agency, and is now working on a malware detector designed to identify viruses on the basis of how they behave, rathe r than on specific patterns in their code, known as signatures. Academic researchers are also inhibited by a certain squeamishness about digital weaponry, according to Herb Lin, chief scientist at the Computer Science and Telecommunications Board of the US National Research Council in Washington DC. He points out that to understand how to guard against cyberattacks, it may help to know how to commit them. Yet teaching graduate students to write malware is very controversial, he says. People say, What do you mean: youre training hackers?' 6.4 Preparing for the Next Attack A study last year by the JASON group, which advises the US government on science and technology matters, including defence, found broad challenges for cybersecurity (JASON Science of Cyber-Security; MITRE Corporation, 2010). Perhaps most important was its conclusion that the field was underdeveloped in reporting experimental results, and consequently in the ability to use them. Roy Maxion, a computer scientist at Carnegie Mellon University in Pittsburgh, Pennsylvania, who briefed JASON, goes further, saying that cybersecurity suffers from a lack of scientific rigour. Medical professionals over the past 200 years transformed themselves from purveyors of leeches to modern scientists with the advent of evidence-based medicine, he notes. In computer science and in computer security in particular, that train is nowhere in sight. Computer science has developed largely as a collection of what Maxion calls clever parlour tricks. For example, at one conference, the leading paper showed how researchers could read computer screens by looking at the reflections off windows and other objects. From a practical point of view, anyone in a classified meeting would go, pooh, he says. In places where they dont want you to know [whats on the computer screen], there are no windows. Yet, that was the buzz that year. Maxion sees an urgent need for computer-science and security curricula to include courses in traditional research methods, such as experimental design and statistics none of which is currently required. Why does it matter? he asks. Because we dont have a scientific basis for investigating phenomena like Stuxnet, or the kind of defences that would be effective against it. Also troubling for many of the Stuxnet investigators was the US governments lacklustre response to the virus (assuming that it was not the perpetrator). Stuxnet represents a new generation of cyberweapon that could be turned against US targets, but there is no evidence that the government is making the obvious preparations for such an attack for example, plans for a coordinated response that pools resources from academia, research institutes and private business. Other countries seem to be taking the threat more seriously. Some of Chinas universities and vocational colleges have reportedly forged strong connections with the military to work on cybersecurity, for example. And Israel also seems to be exploiting its computing expertise for national security. A few months before the discovery of Stuxnet, Yuval Elovici, a computer scientist and director of Deutsche Telekom Laboratories at Ben-Gurion University of the Negev in Beersheba, Israel, told Nature that he was working closely with the countrys Ministry of Defense on cybersecurity. He presciently warned that the next wave of cyberattacks would be aimed at physical infrastructures. What would happen if there were a code injection into SCADA? What if someone would activate it suddenly? Elovici asked. He and other experts have been warning for several years now that such an attack on SCADA systems controlling the electricity grid could spark nationwide blackouts, or that the safety systems of power plants could be overridden, causing a shutdown or a serious accident. Similar disruptions could hit water and sewage systems, or even food processing plants. Such attacks, Elovici warned, are both realistic and underestimated.

The Characterization within Hamlet      Ã‚   This essay will inform the reader regarding the characterization found in Shakespeare’s tragedy Hamlet – whether the dramatis personae are three-dimensional or two-dimensional, dynamic or static, and other aspects of the character portrayal.    John Dover Wilson in What happens in Hamlet tells how the Bard is capable of even bringing realism to a ghost:    Shakespeare’s Ghost is both a revenge-ghost and a prologue-ghost, that is to say from the technical point of view it corresponds with its Senecan prototype. But there the likeness ends; for it is one of Shakespeare’s glories that he took the conventional puppet, humanised it, christianized it, and made it a figure that his spectators would recognize as real, as something which might be encountered in any lonely graveyard at midnight.[. . .] The Ghost in Hamlet comes, not from a mythical Tartarus, but from the place of departed spirits in which post-medieval England, despite a veneer of Protestantism, still believed at the end of the sixteenth century. And in doing this, in making horror more awesome by giving it a contemporary spiritual background, Shakespeare managed at the same time to lift the whole ghost-business on to a higher level, to transform a ranting roistering abstraction into a thing at once tender and majestical. (56-57)    The genius of the Bard is revealed in his characterization.

Review of Literature on Abortion in the Family Essay -- Abortion Pregn

Review of Literature on Abortion in the Family Abortion is a very controversial subject that has been continuously argued over for the past few years and probably for many more years to come. Women who are making the decision are effected emotionally, mentally, and physically since their bodies are going through many changes which it is not accustomed to. The main controversy is, who's right is it to abort? Many will argue and say it is the woman's right to chose what she does with her own body, but what about the father's right? The man's involvement in the abortion decision is not about the woman's choice, it is about his own responsibility to her and the child (Arthur 1999). There are two sides to this abortion topic: the pro-life, which is those who are against abortion altogether, and the pro-choice, or those who believe it is the woman's right to choose if she wants to have an abortion. These two groups offer different solutions to the problem. The pro-life solution is to have the child and basically live with him/her. They believe abortion is not an answer. The pro-choice solution is abortion because of reasons they feel are appropriate. When pregnancy is unwanted women perceive the choice of abortion as the least of three evils: abortion, adoption, or keeping the child (Smith, 2000). Pregnancy changes a woman's life, regardless of whether or not it ends in abortion. The woman making the abortion decision looks at a variety of relationships to help her make the decision. Often, she will discuss her options with a physician or counselor. If she does decide to get an abortion, there are many factors she will have to face. According to an article in Business 2.0, written by David Shribman (2000), women who have had abortions are at greater risk of suffering emotional and psychological problems which may interfere with their ability to concentrate, make decisions, and interact with others. As a result, it reduces the woman's level of job skills and employment opportunities. Post-abortion women are more likely to engage in drug and alcohol abuse, often as a result of the guilt and negative feelings held inside of the m after the abortion. This may prevent them from entering other meaningful relationships. They are likely to become pregnant again and undergo additional abortions and are more likely to never marry, more likely divorce, and m... ... Legal abortion may help parents limit their families to the number of children they want and can afford, both financially and emotionally. Many unwanted babies are abused, neglected, or even killed by uncaring or immature parents (Smith 2000). There is a lack of babies up for adoption because abortion is legal. Perhaps if abortion was illegal, women could go ahead with the pregnancy and then give the baby up for adoption. Abortion is a significant issue in society that has a lot of conflicts. There is still no conclusion because one can see this problem from many different perspectives. If a person supports a pro-life or pro-choice group, they cannot judge objectively if the other group has a different way of thinking. Society cannot judge pro-life activists as a group who have no respect for a woman's right. On the other hand, one cannot say that pro-choice is a better group because they are more aware of human needs. Society will never understand the feelings of a woman who has had an abortion unless they are in her place. To solve this problem, society needs to spend some time to think carefully and to weigh both sides of the issue to make the best decision possible.

Race-Based Jury Nullification Essay

Internet research clearly showed a long history for jury nullification in the US. An explanation of jury nullification, and in particular race based jury nullification, is that it is a method whereby juries nullify unfair laws by declaring guilty defendants not guilty. Race based nullification is where a jury acquits and individual based on their race. This is commonly found in homogenous juries where there is little jury diversity. Past cases such as runaway slave laws and current cases such as police shootings show that race-based nullification is still an issue in modern courtrooms. The conclusion being that jury nullification is an important power necessary for the checks and balances of the judicial system Jury nullification is a right enjoyed, but not understood, by all jurors in the US. This right gives jurors the ability to interpret laws for themselves and return not-guilty verdicts for guilty defendants allowing them to nullify laws. (Emal, 1995) The most common admonishment by judges is that jurors must decide the case based on facts, and that they are not in fact interpreting the fairness of laws. The fear is that if jurors knew or understood this power, it could undermine the authority of the US judicial system. Allowing juries to interpret laws is in fact a right given as a foil against a too powerful central government. Historically there is a tremendous precedent for jury nullification much of it involving race. In the North pre-civil war era juries commonly refused to convict runaway slaves because they felt that the law was unfair. This was an example of jury nullification, where the jury was aware that the defendant was guilty, but refused to return a guilty verdict, in effect nullifying the law. (Emal, 1995) More recently in the 1930’s many courts refused conviction for minor alcohol infractions because they felt the law was unfair. Another example of this trend were the civil rights trials of white supremacists in the south in the 50’s and 60’s; in these cases all white juries would refuse to convict white defendants of the murder of black  people or civil rights workers. (Emal, 1995) These cases clearly show that there have been many examples of jury nullification in the past in our country. Since a return of a not guilty verdict allows the jury to effectively end prosecution with no appeal allowed by the state it means that juries actually have final say about when and if a law is utilized. This allows juries the power to actually use their conscience when voting to convict or release a defendant. One possible outcome of jury nullification is the possibility of a major increase in hung juries. Race has figured in many instances of jury nullification so there is a clear precedent for race based jury nullification. (Emal, 1995) Recently all white juries have refused to convict white police officers in wrongful shooting trials where the victim was black. Also black juries have refused to convict clearly guilty defendants of crimes on the grounds that there are too many black people in prison already. (Butler, 1995) Another possible reason for jury nullification is to punish prosecutors and police for tactics, which the jurors find unpalatable. Many people recently felt that the O.J. Simpson trial was race based jury nullification; similarly the Rodney King trial would be an example. In both of these cases many people felt that the individual was guilty but that they were released because of their race. Some states have proposed that juries should have racial quotas in order to avoid possible race based nullification. In this system jurors who should be excused could be kept even if they were unsatisfactory if they fit some particular racial need. These attempts to eliminate jury nullification point to the seriousness with which this power is viewed. Some black lawmakers have said that since a jury is representative of a community then jurors should have the right to decide which people they will allow to live among them. (Butler, 1995) This basically means that jurors exercise their power based on conscience and not based on the facts of the case. This means that black juries would acquit non-violent black defendants even in cases where they were clearly guilty to nullify the effects of a predominantly white judicial system. The belief here is that the laws are  inherently unfair because they were created by and for white people. (Butler, 1995) Clearly there is a place for jury nullification in the US. There has been a long history of unfair laws and practices in the country and allowing the jury the power to overturn or nullify them is a good way to keep the government in check. (Jones, 2004) The real question is more about race-based nullification. Should race be a factor when juries consider nullification as an option? The answer to this is complicated if a jury really feels that a defendant was targeted unfairly based on race shouldn’t they have some power to affect the trial. (Butler, 1995) Also without a complete revamping of the legal system (scary thought) how would one go about fixing the problem? Can nullification be eliminated with our current system? The idea is to really re-examine the selection process. With nullification as a real possibility then prosecutors can act to eliminate it by paying more attention to homogeneity during the selection process. Any prosecutor who allows a homogenous jury runs a real risk of losing the case based on nullification. Also race based jury nullification has been a useful tool in the past. (Jones, 2004) If not for northern juries how many runaway slaves would have been returned to torture and beatings in the south. In this case we had a manifestly unfair law which juries exercised a legitimate nullification against. Overall race based jury nullification is a scary prospect when taken to the extreme but it is a prospect that bears some consideration. Since it has been used righteously in the past it is a hard decision to contemplate getting rid of it. If there was no jury nullification of any kind then the country would have missed out on juries taking a stand against poorly thought out laws. The answer is that jury nullification has played a dual roll in our history. At times it is a useful tool as in the cases involving slavery or differential prosecution, at times allowing racists to go free. So having weighed the merits of the situation it is best left as is currently. There is a real risk for overuse if everyone were aware of the  power but in its absence the government would exercise too much power unbalanced by the power of the people. The conclusion would have to be that there is too much risk in eliminating jury nullification as a whole. Race based nullification is probably not necessary and would be nice to eliminate but there is no effective way to combat this. One possibility mentioned earlier is for prosecutors to consider nullification during the selection process to help combat this problem. References Butler, Paul. (1998).
