There are very few works not associated with the Western canon to have received as much attention as Chinua Achebe’s novel Things Fall Apart (Ogbaa 1). However, contrary to the many post-colonial interpretations of this novel, this essay employs a psychoanalytical literary approach to discuss the cause of the protagonist’s eventual demise, based on the premise that human behaviour is driven by an unconscious process. Consequently, this essay argues that following the ego’s inability to repress the infantile demands of the unconscious, the preconscious and the conscious self, ever more compulsive, repetitive and neurotic behaviours are displayed. Furthermore, this essay argues that Okonkwo’s relationship to his mother plays a significant role in explaining the tense relationship with his own father and sons. Subsequently, the protagonist’s self-confidence turns to pride and his masculinity develops into totalitarian rule leading to uncontrollable rage, Okonkwo’s world literally falls apart.

As computer and communication networks become prevalent, the Internet has been a battlefield for attackers and defenders. One of the most powerful weapons for attackers is the Internet worm. Specifically, a worm attacks vulnerable computer systems and employs self-propagating methods to flood the Internet rapidly. The objective of this research is to characterize worm attack behaviors, analyze Internet vulnerabilities, and develop effective countermeasures. More specifically, some fundamental factors that enable a worm to be designed with advanced scanning methods are presented and investigated through mathematical modeling, simulations, and real measurements. First, one factor is an uneven vulnerable-host distribution that leads to an optimal scanning method called importance scanning. Such a new method is developed from and named after importance sampling in statistics and enables a worm to spread much faster than both random and routable scanning. The information of vulnerable-host distributions, however, may not be known before a worm is released. To overcome this, worms using two sub-optimal methods are then investigated. One is a self-learning worm that can accurately estimate the underlying vulnerable-host distribution while propagating. The other is a localized-scanning worm that has been exploited by Code Red II and Nimda worms. The optimal localized scanning and three variants of localized scanning are also studied. To fight against importance-scanning, self-learning, and localized-scanning worms, defenders should scatter applications uniformly in the entire IP-address space from the viewpoint of game theory. Next, a new metric, referred to as the non-uniformity factor, is presented to quantify both the unevenness of a vulnerable-host distribution and the spreading ability of network-aware worms. This metric is essentially the Renyi information entropy and better characterizes the non-uniformity of a distribution than the Shannon entropy. Finally, another fundamental factor is topology information that enables topological-scanning worms. The spreading dynamics of topological-scanning worms are modeled through a spatial-temporal random process and simulated with both real and synthesized topologies.

Since the formal implementation of the All-out Defense Education Law, the Ministry of National Defense has actively organized relevant departments and bureaus to promote the ideas of All-out Defense Education policy through a diverse array of publicities and activities. Among these activities, the All-out Defense Military Summer Camp, organized every July and August by integrating the characteristics of all army services, is the most popular activity, and has received wide feedback from the youths. ¡§Actualization of All-out Defense Education policies and in-depth and grass-root work for Total National Defense¡¨ is the theme for the All-out Defense Military Summer Camp organized by the Ministry of National Defense. This study applied the perspective of marketing strategies, and investigated the students attending the ¡§2010 Amphibious Warriors Battle Camp¡¨ using questionnaires. It evaluated student backgrounds and motivation for participation, as well as the relationship with customer equity. Collected data is done through Descriptive Statistics Analysis, such as Independent t-test, One-way ANOVA, Pearson Product-moment Correlation. Conclusion is listed as below: ¡§The summer camp reaches the purpose of All-Out Defense Policy; participants¡¦ motivation is highly influenced by¡¥to become mature¡¦, customer equity is highly influenced by value equity; participants¡¦ motivation and customer equity are highly influenced by some different kinds of background; motivation and customer equity has a positive relationship; three dimensions of customer equity have a positive relationship¡Flots of students have great will to receive the information of army.¡¨ Based on the conclusions, some suggestions proposed as follows: 1. To consider the needs of different targets in detail demands using more accurate market segmentation, and by providing more diverse activities and courses; the activity can be combined with the promotion of the army recruitment policy to improve the many functions and value of combat camps. 2. In order to fully promote the brand of All-out Defense Education policies, ¡§same branding but different marketing targets¡¨ as well as ¡§same brands, different logos and slogans¡¨ can be used in combination with other marketing tactics to improve the understanding and support of citizens to All-out Defense Education policies. 3. To take advantage of social networking websites that many youths and students use to construct an electronic forum or communications platform allowing students from the annual Combat Camps to share their experiences and opinions. At the same time, special activities can be planned for students with exceptional participation to maintaining a strong bond with the customers of All-out Defense Education.

We have been operated the All-out Defense education for five years. The purpose of this study is to investigate the working effectiveness of All-out Defense education. The content of the test was based on ¡§the factors of influencing learning effectiveness¡¨. For supporting the above-mentioned purposes, I used questionnaire investigation method to collect the material data. A total of 570 questionnaires were sent out to a senior high school in Kaohsiung City , and the effective samples are 498. Describing statistics, discriminate analysis, t test, and Pearsonion correlation coefficient, were performedby SPSS statistics software to analyze and explain the raw data. Besides, I have interviewed a teacher who has winned the award of Teaching Excellence recognition in 2010. He made a description of operating the national defense education for the school. The results of this study were analyzed and discussed as follows. First, after operating the national defence education for five years, the preliminary effect has been noticed in the senior high school. Second, there was a significant difference between students¡¦ background and influencing factors of learning. Third, there was no significant difference between students¡¦ background and learning results. Forth, influencing factors have big impact toward learning effectiveness.

Introducing an information system is an organizational learning process, during the process of development an information system , organizational members learn how to introduce information technology into an enterprise. While learning, however, most of individuals always act defensively without any awareness, when solving their problems. For the purpose of Organizational learning, these defensive behaviors will bring counterproductive or unintended consequences or limited learning, and result in the information system which cannot completely meet the business needs or cause project¡¦s schedule delay. In this research, we use the process research model methodology which developed by D. Robey and M. Newman in 1992 year and 1996 year, identify the 16 sequences event process in the case of healthcare information project of E hospital, and define them as either encounters or episodes. From the view of organizational defense, we analyze these events base on the theories of defense mechanism from Argyris and documents about organizational defense from information management. The analyzing results show that there indeed exist many defensive behaviors during the development of project of E hospital, and thus cause negative effect. This research offers these defensive phenomenon for the CIO and project managers to take precaution against same mistake while implementing information project, and help organizational members learning effectively while introducing an information system, in order to reduce risk of project failure and improve control of information project¡¦s cost, quality and schedule.

This thesis analyzes the Western missile defense initiatives and their role in Russia&#039 / s relations with NATO and the U.S. The main question of this thesis is whether the Western missile defense initiatives have paved the way for a new era of cooperation between Russia and the West or not. The main argument of this thesis is that Russia has failed to collaborate with NATO in a meaningful manner on missile defense issue as Russia has not adjusted its security policies and nuclear strategy, which are still based on the Cold War thinking, to the changing conditions of global security in the post Cold War era. The missile defense initiatives have a negative impact on the relations between Russia and the West due to the intransigent stance of Russia on this issue. A robust cooperation can only be achieved between Russia and NATO if Moscow changes its Cold War mentality about global security issues.

From Britain¡¦s point of view, the problems of security and defense in India subcontinent were far greater than those of the maintenance of law and order and imperial rule in the subcontinent itself. For Indian subcontinent, it was the pivot of British power in all of Asia. Furthermore, British possessed the maritime supremacy, the main threat came from the land, especially form the Northwest frontier. British strategy for the defense of India¡¦s land frontiers was based on the following three points: (1) to maintain firm military strength in the most vulnerable parts of the frontier, i.e., the Northwest frontier and Baluchistan, and to keep the tribes of this area pacified or under their control by ¡§divide and rule¡¨ tactics, for the purpose of consolidating integrity of the Northwest frontier and the security of India subcontinent; (2) to encourage the establishment of a string of buffer states all along the perimeter of the subcontinent and to maintain influence or friendly relations with them; and (3) to prevent any contiguous territory and states form coming under the control of a strong power, notably Russia, if necessary by forceful means. Although there are many historical and geographic constraints in South Asia defense considerations, the present defense strategy of India has to be designed to meet the new circumstances. Throughout the years of independence the main security concern of India has been defense over both land and sea problems. On land, India has to handle the relationship with Pakistan and protect the Northeast frontier against the threat from China. In the past, the Northwest frontier was an unified area, after the retreat of British power in 1947, the geographical and strategic unity of the India subcontinent was broken. Moreover, India has nearly a coastline of 7,000 km long, but India doesn¡¦t have the maritime supremacy, so that it should be compelled to deal with potential threat from India ocean.

Research for the military mission of disaster-relief, take mental Health work for example Abstract National defense means defense of the national security. No matter in peacetime or wartime, the military mission of protecting the country is to ensure the welfare of the people and the national security under the consensus of civil defense. The motive of this research originates from the experience of the researchers who were actually involved in the disaster mental health work. Based on the aspect, the research deliberates on the problems which the military faces during the time of disaster-relief, and facilitates the positive effect and response of ¡§the civil mobilization¡¨. The purpose of the research is to adapt the military mission and the disaster mental health work, so that those will accord with the transformation of national defense policy and military thought. The text mainly discusses the differences between the real experience and the policy of mental health, and focuses on the valuable experience of the key persons, which collects the opinions from the papers and investigation. In the view of overall considerations and public policy, it researches about the development and meaningful framework of the disaster mental health work and the way which makes the military receiving much better care and multicultural counseling. The results also provide a reference about the research of the military mental health work. ¡§The national defense is not only the combat, but also the honorable career.¡¨ Nowadays, the military execute the mission of domestic disaster-relief lawfully. It is not only a kind of social responsibility, but also suits the wishes of the society. The long-term development of disaster mental health work can exhibit the professional value of the modern military. ¡¨To accept and win the traditional or modern war at the same time¡¨ is worth the common hopes of the civil. We hope much more that, when the disasters occur and threaten the beautiful island, Taiwan, the military can tell the civil at the first time:¡¨ Be relieved, The military are already ready for anything¡¨.

The steps by which neutral, random and/or negative biological interactions evolve into mutualistic ones remain poorly understood. Here, we study Elacatinus gobies and the fishes from which they clean parasites, termed 'clients'. Colorful stripes are common to mutualist cleaners and non-cleaning sister species. Blue stripes are unique to obligate cleaners. We quantified the contrast potential of ancestral and novel stripe colors, using fish color vision models, and determined that color stripes have become more visible to clients over evolutionary time. In turn, we focused on the role of color as a potentially specialized signal. We show that cleaners possess a putative chemical defense (one multimedia file in .mov format included) and demonstrate that stripes are sufficient to elicit client stereotypical posing behavior and to deter attack. Analysis of previously published records show that yellow cleaners tend to predators less than expected, compared to green and blue cleaners. Our results highlight evolution from predator avoidance to tolerance with conspicuous advertising reinforced by chemical defense in cleaners. Similar trajectories, via recognizable signals to risky partners, may be common in other diffuse mutualisms. We discuss the generality of defense and signal traits in other species rich lineages of mutualists.

<p>Takeovers are used as a mean for companies to grow and gain entry to new markets. Hos-tile takeovers, apart from the friendly takeovers, is when an acquirer tries to takeover a corporation against the will of management, shareholders and board of directors of the target company. All listed companies run the risk of being a target for a hostile takeover, and to-day many companies are trying to involve actions protecting them from possible threats. Lacking protection can evolve into a costly defense program with actions with fictitious names such as White knight, Pac-man and Poison pills. The purpose with this thesis is to describe and analyze hostile takeovers and hostile takeover attempts in Sweden, and the defense tactics involved in the process.</p><p>In this thesis a deductive approach will be used, where theories are used as guidance when searching for explanations. On the basis of the defense tactics described in the theory empirical data has been gathered with the purpose of seeing if the expectations reflect reality, and conclusions about their efficiency. The thesis has used a quantitative research method where the focus is on what, where and when. The aim of the thesis is to classify targeted features and count them, with the intent to construct statistical models with an underlying purpose of explaining what is observed.</p><p>The most frequently used defense tactic used by the target company in a hostile takeover in the Swedish market is to attack the logic of the bid. Around 56 percent of the targets in a hostile takeover or a hostile takeover attempt have used this defense tactic to avoid a hos-tile takeover. The aim with an implemented defense tactic is to avoid a hostile bid or making it impossible for the hostile bidder to proceed with the bid and close the deal. The White knight and White squire defense tactic is the most successful defense tactic when it comes to not finalizing the hostile bid, in 90 percent of the cases the deal is not closed if the target chooses to use a White knight as a defense tactic. A secondary objective with a defense tactic is to force the hostile bidder to increase the bid and pay more for the target company. In the Swedish market, the use of Corporate restructuring as a defense tactic has made the hostile bidder to increase the bid in 67 percent of the cases and the use of Positive public information has forced the hostile bidder to increase the bid in more than half of the cases.</p><p>The question why these defense tactics are the most frequently used strategies, is explained by two variables. The first one is the cost and simplicity variable, where Attack the logic of the bid and Public information ends up. These defense tactics are cost efficient and can be seen as natural step for the target company when deciding not to approve of the offer made by the acquirer. The second variable is the proven efficiency, where the target knows if implementing this defense tactic the risk of being acquired by the hostile bidder is relatively low, a good example of this is the White knight defense.</p>
