Dauberman, Jamie. "Making decisions about screening cargo containers for nuclear threats using decision analysis and optimization." VCU Scholars Compass, 2010. http://scholarscompass.vcu.edu/etd/2240.
Full textAbstract:
One of the most pressing concerns in homeland security is the illegal passing of weapons-grade nuclear material through the borders of the United States. If terrorists can gather the materials needed to construct a nuclear bomb or radiological dispersion device (RDD, i.e., dirty bomb) while inside the United States, the consequences would be devastating. Preventing plutonium, highly enriched uranium (HEU), tritium gas or other materials that can be used to construct a nuclear weapon from illegally entering the United States is an area of vital concern. There are enormous economic consequences when our nation's port security system is compromised. Interdicting nuclear material being smuggled into the United States on cargo containers is an issue of vital national interest, since it is a critical aspect of protecting the United States from nuclear attacks. However, the efforts made to prevent nuclear material from entering the United States via cargo containers have been disjoint, piecemeal, and reactive, not the result of coordinated, systematic planning and analysis. Our economic well-being is intrinsically linked with the success and security of the international trade system. International trade accounts for more than thirty percent of the United States economy (Rooney, 2005). Ninety-five percent of international goods that enter the United States come through one of 361 ports, adding up to more than 11.4 million containers every year (Fritelli, 2005; Rooney, 2005; US DOT, 2007). Port security has emerged as a critically important yet vulnerable component in the homeland security system. Applying game theoretic methods to counterterrorism provides a structured technique for defenders to analyzing the way adversaries will interact under different circumstances and scenarios. This way of thinking is somewhat counterintuitive, but is an extremely useful tool in analyzing potential strategies for defenders. Decision analysis can handle very large and complex problems by integrating multiple perspectives and providing a structured process in evaluating preferences and values from the individuals involved. The process can still ensure that the decision still focuses on achieving the fundamental objectives. In the decision analysis process value tradeoffs are evaluated to review alternatives and attitudes to risk can be quantified to help the decision maker understand what aspects of the problem are not under their control. Most of all decision analysis provides insight that may not have been captured or fully understood if decision analysis was not incorporated into the decision making process. All of these factors make decision analysis essentially to making an informed decision. Game theory and decision analysis both play important roles in counterterrorism efforts. However, they both have their weaknesses. Decision analysis techniques such as probabilistic risk analysis can provide incorrect assessments of risk when modeling intelligent adversaries as uncertain hazards. Game theory analysis also has limitations. For example when analyzing a terrorist or terrorist group using game theory we can only take into consideration one aspect of the problem to optimize at a time. Meaning the analysis is either analyzing the problem from the defenders perspective or from the attacker’s perspective. Parnell et al. (2009) was able to develop a model that simultaneously maximizes the effects of the terrorist and minimizes the consequences for the defender. The question this thesis aims to answer is whether investing in new detector technology for screening cargo containers is a worthwhile investment for protecting our country from a terrorist attack. This thesis introduces an intelligent adversary risk analysis model for determining whether to use new radiological screening technologies at our nation’s ports. This technique provides a more realistic risk assessment of the true situation being modeled and determines whether it is cost effective for our country to invest in new cargo container screening technology. The optimal decision determined by our model is for the United States to invest in a new detector, and for the terrorists to choose agent cobalt-60, shown in Figure 18. This is mainly due to the prominence of false alarms and the high costs associated with screening all of these false alarms, and we assume for every cargo container that sounds an alarm, that container is physically inspected. With the new detector technology the prominence of false alarms decreases and the true alarm rate increases, the cost savings associated with this change in the new technology outweighs the cost of technical success or failure. Since the United States is attempting to minimize their expected cost per container, the optimal choice is to invest in the new detector. Our intelligent adversary risk analysis model can simultaneously determine the best decision for the United States, who is trying to minimize the expected cost, and the terrorist, who is trying to maximize the expected cost to the United States. Simultaneously modeling the decisions of the defender and attacker provides a more accurate picture of reality and could provide important insights to the real situation that may have been missed with other techniques. The model is extremely sensitive to certain inputs and parameters, even though the values are in line with what is available in the literature, it is important to understand the sensitivities. Two inputs that were found to be particularly important are the expected cost for physically inspecting a cargo container, and the cost of implementing the technology needed for the new screening device. Using this model the decision maker can construct more accurate judgments based on the true situation. This increase in accuracy could save lives with the decisions being made. The model can also help the decision maker understand the interdependencies of the model and visually see how his resource allocations affect the optimal decisions of the defender and the attacker.

Thesis: S.M., Massachusetts Institute of Technology, Department of Mechanical Engineering, 2016.<br>This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.<br>Cataloged from student-submitted PDF version of thesis.<br>Includes bibliographical references (pages 135-137).<br>The OFNP research group in the Nuclear Science and Engineering Department at MIT is developing a power plant that combines two well-established technologies -- light water reactors and offshore platforms -- into a new design called the Offshore Floating Nuclear Plant (OFNP). Deploying a nuclear reactor aboard a floating platform up to 12 nautical miles into the ocean raises unique security questions and considerations. This investigation presents a framework for analyzing the threat of intentional ship collision, modeling damage and characterizing the effectiveness of potential solutions, as well as integrating or adapting the recommended security strategies into existing regulatory and legal environments. First, a collision risk assessment is completed and a postulated design-basis collision threat (DBT) is determined to be a 150,000 DWT ship. Next, using the DBT characteristics and the finite element modeling software ABAQUS, estimations for damage are provided for a reference case and for cases with variations in collision characteristics. Results indicate increased ship penetration from faster and larger ships, wedge-shaped ship hulls, fixed OFNP moorings, direct broadside collisions, and OFNP designs with less internal structural support. Additionally, in order to minimize risk of unacceptable damage, the results indicate that vessels larger than 70,000 DWT should be restricted from entering within an eight-nautical mile exclusion zone. The results from the previous assessments are then used to present technical, operational, and regulatory recommendations for damage mitigation. The analysis concludes with an assessment of the existing regulatory and legal environments in which the regulatory solutions would have to be implemented, provides an analysis of the degree to which the ideal regulations comply with existing laws, and then culminates with the presentation of further recommendations and a regulatory strategy framework for meeting security goals while achieving legal compliance. In summary, this investigation considers the threat of intentional collision with an Offshore Floating Nuclear Plant and utilizes risk assessment techniques, numerical modeling, and legal research to contextualize the threat, model possible damage, and present technical, operational, and regulatory solutions for avoiding or mitigating damage.<br>by Grant Norman Genzman.<br>S.M.

Full textAbstract:
This doctoral thesis ("Signs of Danger/Dangerous Signs: Responding to Nuclear Threat") is a poststructural, interdisciplinary exploration of the social, political and cultural workings of nuclear threat. Drawing extensively on a nuclear waste burial initiative being undertaken by the United States Department of Energy, this work is a detailed critical analysis of the relationships between the threats posed by nuclear wastes, and the responses provoked in relation to such threats.<br>Working through such theorists as Jacques Lacan and Slavoj Zˆizˆek (the second death, and le Reel), Francois Ewald (thresholds), Ulrich Beck (risk society), and Felix Guattari (ecology of the virtual), this work demonstrates the manner in which ecological threats, such as that posed by the nuclear, are (paradoxically) "creative" forces; that is, they have a propensity to cut through traditional social divisions (e.g., class, race), assembling news lines of affinity, and new constituencies of those at risk. Indeed, it seem that nuclear threat constitutes a novel form of threat. A form of threat that is irreducibly material, yet admits of no objective ground upon which decisions may be made. A form of threat that threatens the very biological foundations of life, yet whose ontology is to be determined through social and cultural responses.<br>The principle critical figure I use to analyse and illustrate the movement of threat is the vast monument/sign which is to be constructed above the Waste Isolation Pilot Plant (WIPP) in the desert near Carlsbad, New Mexico. If constructed, this monument will be one of the largest public works project in history. The purpose of this monument is to signify the danger which is to be buried below and thereby deter---for a legislated period of 10,000 years---inadvertent human intrusion into the site. Through analyses of the semiotic issues raised by the desert monument, the appropriation of the practice of burial and its relations to cultural conceptions of death, and the use of the desert as the mise-en-scene of waste, this dissertation shows how the larger context of waste burial demonstrates an extreme and unexamined field of cultural trauma and disavowal around issues of nuclear threat.

Full textAbstract:
<p>The thesis argues that, as a tradition, the concept of just war is socially and contextually sensitive and revisable. It explores the relevance of theory according to the dynamic changes in the nature of threats in the international arena and concludes that the just war tradition is still relevant to the contemporary modern threats that require an act of pre-emptive warfare. However, it needs some revision to be comprehensively applicable to the dynamic of modern threats and the nature of pre-emptive war. Due to the nature of pre-emptive war a nation launches the attack before the aggression from the other nation-in-conflict erupts. The author, therefore, proposed several theoretical and procedural revisions in both the principle of “Jus Ad Bellum” and “Jus In Bello” using the method of reflective equilibrium to create a comprehensive “just” pre-emptive war doctrine as part of the development and dynamic in just war tradition.</p>

Full textAbstract:
Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Nuclear Engineering, 2005.<br>Includes bibliographical references (p. 87-90).<br>In recent history, nuclear engineers and the nuclear power industry have been primarily concerned with two things: safety and waste. In the past few years, a third concern has risen to join these two at the top: terrorism. This change occurred on September 11, 2001. Americans now realize that terrorists are willing and able to attack on their home soil and that terrorists have no qualms about attacking civilians. This thesis examines in detail why people are especially afraid of nuclear power, from the standpoint of both safety and terrorist threats, more so than the other risks that we face everyday. This thesis then explores the role of the press in influencing and being influenced by public perception. The conclusions of this thesis can be boiled down to these main points: (1) The publics fear of terrorism against a nuclear facility has the same roots as the fear caused by safety concerns over nuclear power, and the strongest of these roots is the association of all things "nuclear" with the threat of nuclear war. (2) Terrorism risk perception is largely influenced by proximity to a particular threat. That is, people see more risk in threats that are close to themselves or their loved ones. Likewise, authorities assume that the public perceives greater risk in their particular area of responsibility.<br>(cont.) (3) Since the purpose of terrorism is to incite terror, the public perception of nuclear power plants as tempting terrorist targets may be self-fulfilling. (4) Any public action by government or industry leads to increased media coverage, and any media coverage, positive or negative, increases public fear. Therefore, the nuclear establishment should take no action to lower terrorism risk with the hope that it will allay public concern. Instead, the establishment should take whatever reasonable actions it thinks will reduce the actual risk and make appropriate emergency response preparations, while avoiding additional media coverage.<br>by Mark Laughter.<br>S.M.

Full textAbstract:
Approved for public release, distribution unlimited<br>This thesis explores the threat, if any, posed to the United States by the Iranian nuclear program. Specifically, it addresses whether Iran's pursuit of nuclear technology is likely to represent a threat for homeland defense (direct use of nuclear weapons) or homeland security (indirect use of nuclear weapons through intermediaries). It begins with an overview of the cooperation and conflict between the U.S. and Iran on a number of issues, but primarily in regard to nuclear technology. Next, it addresses Iranian intentions, motivations, and rationality for developing nuclear technology. The possible employment options for Iranian nuclear weapons are then reviewed and assessed in terms of their likelihood based on historical models of deterrence derived from the U.S.-Soviet relationship during the Cold War (direct use), as well as theoretical models of Pakistan's development of nuclear weapons (indirect use). It appears that Iran's pursuit of nuclear technology results from a combination of security concerns, pride, prestige, and a desire for regional leadership. Iran has rational motivations for pursuing nuclear technology; therefore, U.S. leaders should approach Iran as a rational actor in order to avert further conflict between the two states.

This thesis is a study of the British intelligence assessments produced by the UK's Joint Intelligence Committee regarding the Soviet Union's nuclear capabilities and intentions. It examines the origins of such intelligence, the various organisations that collected, collated and analysed it and how it fed into the Joint Intelligence structure. The thesis seeks both to synthesise existing historical analysis and add new evidence on intelligence organisation, collection, analysis and dissemination by examining the development of such assessments over a twenty-five year period and considering how well they reflected and informed British governments about the status and progress of the Soviet nuclear threat. Lastly, it analyses how this intelligence fed into and may have affected wider British military and ministerial decision-making regarding the course of the UK's nuclear weapons policy between 1945 and 1970.

Full textAbstract:
This thesis draws on evidence from interactions between China and India over the past few years to make an empirical case for the existence and impact of asymmetrical perceptions of threat between the two countries. The major issues of China-India relations, including the nuclear issue, the boundary problem, the Tibet issue, regional competition and cooperation, and China-India relations in the global context, are examined. The first aim of the thesis is to highlight the asymmetry of the threat perceptions between China and India and has explained the interactions of Sino-Indian relations. India tends to be deeply apprehensive of threats from China, while China appears comparatively unconcerned about threats from India. The second contention in this study is that Sino-Indian relations are constrained by the asymmetry between their threat perceptions. The asymmetry in perceptions of threat will result in a dilemma for India. India will try to reduce the sense of insecurity by adopting some countermeasures, such as developing nuclear weapons, allying with other countries, and undermining China's influence. However, India is also very cautious and avoids angering China. On the contrary, China will be in favour of the status quo, and feel no urgent need to sort out the boundary disputes. The Chinese side has ignored the asymmetry and is in no mood to share India's expectations and concerns. Thus, this thesis argues that this asymmetry has made it difficult for China and India to forge shared knowledge and to set a common agenda around which their expectations could converge. India will be on a perennial quest for changes in Sino-Indian relations, such as a final resolution of the border issue and securing more credible nuclear deterrent against China. The asymmetry in threat perceptions is seen as a destabilising factor in China-India relations.

Full textAbstract:
Approved for public release; distribution unlimited.<br>The continuing efforts of several developing nations to acquire nuclear weapons
indicates that the United States may be required to implement a deterrence policy aimed at
authoritarian regimes in the Third World. Therefore. U. S. decision-makers must re-evaluate
the conceptual foundations of American deterrence policy. This research suggests a solution
to the problem of deterring nuclear-capable Third World nations from using nuclear
weapons against the United States, its allies and friends. The new deterrence policy is based
on the theory of omnibalancing which predicts that the Third World dictators are strongly
influenced by perceived internal threats to their regime. Successful deterrence, therefore, is
dependent on holding at risk the mechanisms used by Third World authoritarian regimes to
maintain internal control. Although developing a nuclear deterrence policy against Third
World dictators is critical to the security of the United States, there has been a hesitancy for
Western analysts to consider the problem of Third World nuclear deterrence because they
either perceive that these regimes are irrational and therefore non-deterrable or they believe
that the U.S. nuclear arsenal in itself will provide deterrence. This analysis addresses the flaws of these perceptions and offers an analytical basis for new U.S. strategic thinking about
deterrence and the Third World. A deterrence policy based on omnibalancing can be a
viable means of preventing Third World nuclear use against the United States and its
interests.

Full textAbstract:
Canadians faced an unprecedented threat after the Second World War. Located between two competing superpowers Canada could become the battlefield of a third world war. How did Canadians respond to the nuclear threat? The government of John Diefenbaker warned that millions of Canadians could die in a nuclear war. It strengthened Canada's contribution to the defence of North America and Europe and dedicated more resources to civil defence. Between 1957 and 1963 the domestic issue of nuclear arms acquisition and growing cold war tensions combined to draw attention to the threat. Newly founded anti-nuclear groups as well as Canadian unions, newspapers, magazines, student groups, churches and community organizations confronted nuclear issues. These groups shared a concern about survival but reached different conclusions about how Canada could avoid nuclear devastation. Their attempts to come to terms with the threat of nuclear war highlight broader themes in the history of postwar Canada including the influence of the cold war on the attitudes and behaviours of Canadians and the nation's relationship with the United States.<br>While more Canadians discussed the nuclear threat in these years the majority did not join the debate. Polls showed the public supported a nuclear defence. They believed few would survive a nuclear attack but did not worry about nuclear war. Economic concerns always ranked higher. The public was, on the whole, not mobilized either in preparation or in protest. Diefenbaker questioned what else he could do to increase public concern about survival. Both the civil defence program and the nuclear disarmament movement struggled. Polls showed that most Canadians did nothing to prepare for a war fought at home. Anti-nuclear groups remained small, divided over their platforms and methods and faced financial constraints. The debate about survival grew in the period between 1957 and 1963 but was dominated by elected officials, civil defence authorities and anti-nuclear activists. Even these groups found it difficult to balance the Soviet threat with the risk of a nuclear war and struggled to achieve policies that would provide security for the nation and its population.

Arnold, Jacquelyn. "British civil defence policy in response to the threat of nuclear attack, 1972-1986." Thesis, London Metropolitan University, 2014. http://repository.londonmet.ac.uk/1287/.
Full textAbstract:
This thesis investigates how successive British governments in the last two decades of the Cold War developed and adapted civil defence policies aimed at mitigating the effects of a nuclear attack on the population of Britain. It tests the hypothesis that civil defence in Britain from 1972 until 1986 was shaped by three distinct influences; economic, ideological and external. It establishes in which ways and to what extent policy was shaped by these factors and which, if any, was the primary determinant of the major policy decisions of the time. It explains how changing economic, ideological and external contexts fused those policies with the political framework during those 15 years. It examines the theory and reality of civil defence, from its rebirth as a political and practical concern in 1972 until the end of civil defence as a practical and political response against a specific nuclear threat in 1986. It does so within the framework of a wider Cold War defence policy and explains how policy assumptions were constituted and perpetuated. By extrapolating and further analysing the idea of policy development as a direct result of certain key factors, this thesis charts the conceptualisation and evolution of civil defence through its fluctuating humanitarian, political, insurance and deterrent functions by which such policy may be explained and understood. The thesis concludes that determining one dominant influence from within the intensely symbiotic relationship of ideology, economics and external affairs is problematic. Rather it can be seen that the initiation of civil defence policy was the aspect of the policy cycle most closely influenced by ideology. The later formulation and implementation of that policy was primarily determined by the economic resources available. The ultimate existence of civil defence in its manifestation as protection against nuclear attack was wholly a reaction to the shifting developments of international affairs.

This Master Thesis aims to present the current existential threats to Israeli security. Israel is a Jewish country in the middle of the Muslim region and her demise is wished by many involved parties. The Author describes sophisticated security systems of Israel, their efficiency and its unofficial nuclear program. From the state actors, it is Iran that has become the number one perceived threat in Israel thanks to its officials' rhetoric, its support towards terrorist organizations and its nuclear program. Israel is often involved in asymmetrical conflicts against non-state actors like Hamas and Hezbollah. The new extremist group Islamic State can also potentially pose a threat. Has Israel got reasons to worry about her existence? Has the Arab Spring brought about positives, negatives, or new possibilities? The Author aims to answer these questions.

The PPS is an integrated system of people, equipment and procedures used to protect nuclear facilities and radioactive sources against threat, theft or sabotage. The PPS works to avoid, to mitigate or to minimize the consequences caused by these actions. This study evaluates the PPS of the reactor, identifying the vulnerabilities and suggesting ways to improve the system effectiveness. The analyses were based on the methodology developed by Sandia National Laboratories´ security experts in AlbuquerqueUSA, allowing the system evaluation through hypothetical and probabilistic analyzes; identifying threats, determining the targets and analyzing the possible adversaries paths. From the methodology adopted was obtained the value around 40% for PE indicator, which shows the need to improve the system to minimizing the vulnerabilities.

Thesis advisor: Michael A. McDannald<br>Identifying the neural circuits underlying adaptive fear is fundamental to understanding and developing more effective treatments for anxiety disorders. Adaptive behavior requires fear to scale to the level of threat and dysfunction in this capacity is a hallmark of fear-related anxiety disorders. Identifying the neural circuits underlying adaptive fear is fundamental to understanding anxiety disorders and propelling more effective treatments for patients. Fear is adaptive when the level of the response rapidly scales to degree of threat. Using a discrimination procedure consisting of danger, uncertainty, and safety cues, our laboratory has found rapid fear scaling (within 2 s of cue presentation). However, the neural underpinnings of this behavior are unknown. The overarching goal of this dissertation is to examine a role for the nucleus accumbens core (NAcc) in scaling fear to degree of threat. In three experiments I used neurotoxic lesions, optogenetic inhibition, and in vivo electrophysiology combined with an intricate fear learning procedure to elucidate a role for the NAcc in both general and rapid scaling of fear. Permanent NAcc dysfunction, via neurotoxic lesion, generally disrupted the ability to scale fear to degree of threat and specifically impaired one component of scaling: rapid discrimination of uncertain threat and safety. Reversible NAcc dysfunction, via optogenetic inhibition, specifically impaired rapid discrimination of uncertain threat and safety. Further, I demonstrated that NAcc activity is threat responsive and exhibits heterogeneity in the timing and specific nature of threat firing. The results reveal that the NAcc is essential to scale fear to degree of threat and responds to threat cues across both rapid and general timescales. Taken together, the results reveal a novel role for the NAcc in scaling fear and identify it as a plausible source of dysfunction in stress and anxiety disorders.

South Korea’s security discourse on the nuclear threat posed by North Korea has been dichotomised by its position within the political spectrum between the progressives and conservatives. By drawing upon Securitisation Theory (ST), this study challenges the current security discourse in South Korea, which has divided and misled the public as well as securitising actors. This study examines the security discourses of the Roh Moo-hyun (2003–2008) and Lee Myung-bak (2008–2013) administrations, since they represent the archetypes of the progressives and conservatives respectively. The results of the analysis suggest that the current security discourses that have been prevalent in South Korea do not correspond with reality and, subsequently, the discourses were not able to deal with real challenges that the nuclear threat posed. This research also explains the root cause of the distorted security discourses by applying a ‘discursive chasm’ as a preliminary concept, which indicates a discursive structure that fundamentally impedes the performance of securitising actors’ articulation, and that distorts the discursive formation (securitisation processes). The chasms consist of three elusive discourses: first, a discourse on threats that cannot simply be said to be either imminent or not imminent (nuclear weapons as materiality and discourse); second, a discourse on the other that cannot easily be defined (the difficulty of representation of North Korea); and third, a discourse on measures that cannot easily be realised (intangible extraordinary measures).

Full textAbstract:
Effective use of Machine Learning to support extracting maximal information from limited sensor data is one of the important research challenges in robotic sensing. This thesis develops techniques for detecting and characterizing patterns in noisy sensor data. Our Bayesian Aggregation (BA) algorithmic framework can leverage data fusion from multiple low Signal-To-Noise Ratio (SNR) sensor observations to boost the capability to detect and characterize the properties of a signal generating source or process of interest. We illustrate our research with application to the nuclear threat detection domain. Developed algorithms are applied to the problem of processing the large amounts of gamma ray spectroscopy data that can be produced in real-time by mobile radiation sensors. The thesis experimentally shows BA’s capability to boost sensor performance in detecting radiation sources of interest, even if the source is faint, partiallyoccluded, or enveloped in the noisy and variable radiation background characteristic of urban scenes. In addition, BA provides simultaneous inference of source parameters such as the source intensity or source type while detecting it. The thesis demonstrates this capability and also develops techniques to efficiently optimize these parameters over large possible setting spaces. Methods developed in this thesis are demonstrated both in simulation and in a radiation-sensing backpack that applies robotic localization techniques to enable indoor surveillance of radiation sources. The thesis further improves the BA algorithm’s capability to be robust under various detection scenarios. First, we augment BA with appropriate statistical models to improve estimation of signal components in low photon count detection, where the sensor may receive limited photon counts from either source and/or background. Second, we develop methods for online sensor reliability monitoring to create algorithms that are resilient to possible sensor faults in a data pipeline containing one or multiple sensors. Finally, we develop Retrospective BA, a variant of BA that allows reinterpretation of past sensor data in light of new information about percepts. These Retrospective capabilities include the use of Hidden Markov Models in BA to allow automatic correction of a sensor pipeline when sensor malfunction may be occur, an Anomaly- Match search strategy to efficiently optimize source hypotheses, and prototyping of a Multi-Modal Augmented PCA to more flexibly model background and nuisance source fluctuations in a dynamic environment.

Full textAbstract:
This dissertation examines how the major television networks, in conjunction with the Reagan administration, launched a lingering cloud of nuclear anxiety that helped to revive the Cold War during the 1980s. Placed within a larger political and cultural post-war context, this national preoccupation with a global show-down with the Soviet Union at times both hindered and bolstered Reagan’s image as the archetypal conservative, cowboy President that could free America from its liberal adolescent past now caustically referred to as “the sixties.” This stalwart image of Reagan, created and carefully managed by a number of highly-paid marketing executives, as one of the embodiment of peaceful deterrence, came under attack in the early 1980s when the “liberal” Nuclear Freeze movement showed signs of becoming politically threatening to the staunch conservative pledging to win the Cold War at any cost. And even if the nuclear freeze movement itself was not powerful enough to undergo the Herculean task of removing the President in 1984, the movement was compassionate enough to appeal to a mass audience, especially when framed in narrative form on network television. In the early 1980s, debates over the possibility of nuclear war and other pertinent Cold War related issues became much more democratized in their visibility on the network airwaves. However, the message disseminated from the networks was not placed in an educational framework, nor did these television productions clarify complicated nuclear issues such as nuclear winter theory and proliferation. I argue this renewed network attention on nuclear issues was not placed in an historical framework and likely confused American viewers because it routinely exposed audiences to both fact and fiction, undifferentiated at the level of the mass media.

Full textAbstract:
La fin de la confrontation Est-ouest va apparaître comme un tournant décisif dans la lutte contre la prolifération des armes nucléaires. Alors que le monde se réjouissait de la chute du mur de Berlin, le contexte qui va succéder à cette période est marqué par la poursuite, et même l’aggravation de plusieurs crises graves liées à la prolifération nucléaire en Inde, au Pakistan, en Iran et en Corée du Nord. Ces crises, intervenues alors même que la totalité des armes nucléaires à l’échelle mondiale avait été réduite de plus d’un quart depuis la fin de la guerre froide, ont fait l’objet d’une réaction mitigée de la part de la « communauté internationale ». Ces crises montrent qu’il est indispensable de renforcer le régime de non-prolifération nucléaire en apportant des réponses promptes, crédibles et dynamiques. Alors que des doutes sont apparus sur la capacité du régime classique à décourager ceux qui souhaitent développer des activités nucléaires à des fins autres que pacifiques, la nécessité d’envisager des outils modernes et adaptées au contexte géopolitique en pleine mutations, s’est révélée indispensable. Cela suppose un réaménagement du régime classique de non-prolifération dans la perspective de renforcer la légitimité de la norme de non-prolifération. De surcroît, ces crises montrent qu’il est indispensable de renforcer les mécanismes de mise en œuvre du Traité de non-prolifération nucléaire (TNP). Il s’agira d’assurer l’application universelle des accords de garanties de l’AIEA, qui est une obligation du TNP, ainsi que par l’universalisation du protocole additionnel<br>The end of the East-West confrontation appeared to be a watershed in the fight against the proliferation of nuclear weapons. While the world was celebrating the fall of the Berlin wall, the context that will succeed this time is marked by the continuity and the aggravation of several serious crises linked to nuclear proliferation in India, Pakistan, Iran and North-Korea. These crises occurred even though all nuclear weapons were globally reduced by more than a quarter since the end of the cold war, have been a mixed reaction from the " International community ". These crises show that it is essential to strengthen the nuclear non-proliferation system by providing prompt, credible and dynamic responses. While doubts have been raised about the ability of the classical regime to discourage those who wish to develop nuclear activities for other than peaceful purposes, the need to consider appropriate modern tools to change rapidly geopolitical context seemed to be essential. This implies a rearrangement of the classic nuclear non-proliferation system with a view to strengthen the legitimacy of the norm of non-proliferation. In addition, these crises show that it is essential to strengthen the mechanisms for implementation of the Treaty on the non-proliferation of nuclear weapons (NPT). The application of an additional protocol, coupled with the implementation of a comprehensive safeguards agreement, is indeed essential to obtain full insurance compliance with non-proliferation commitments and is the current standard to allow the agency (IAEA) to fulfill its mission

Full textAbstract:
Ancien élève de Husserl et Heidegger, Günther Anders (1902-1992) composa une oeuvre philosophique dont la particularité est d'interroger la situation de l'homme face aux événements les plus sombres du 20e siècle. Ce travail, élaboré à partir d'une lecture de l'oeuvre éditée à ce jour, complétée par celle du Nachlass, vise à ressaisir l'unité, la cohérence et la singularité de sa pensée autour d'une question majeure : comment un monde technicisé, un monde sans hommes, est-Il compatible avec une éthique pour des hommes sans monde ? Décrire les ombres du monde, celles d'abord laissées par un monde humain technicisé, c'est déceler les idéalités de la technique qui recouvrent chaque chose d'une évidence artificielle. Observer le monde fabriqué par des hommes devenus des ombres, c'est aussi percevoir qu'ils peuplent un environnement dont ils sont les produits. Ce monde artificiel, à défaut de ne faire que soulager l'hostilité naturelle, ajoute d'autres souffrances au poids de la nécessité, que les arts parviennent à peine à déjouer. Théoriser les ombres du monde, c'est relever la négativité d'un nihilisme réalisé par la technique, à refuser. L'hypothèse philosophique ici défendue est celle d'un nihilisme métaphysique conçu comme préalable nécessaire au refus de toute autre pratique nihiliste. A cet effet, à partir de l'oeuvre d'Anders se conçoit une philosophie occassionnelle comme pratique théorique d'une sobriété tragique. Si briser toute idée métaphysique aboutit à désenchanter les victimes de trop naïves généralités, cette théorie n'impose cependant en rien de s'interdire de faire de la métaphysique<br>As a former student of Husserl and Heidegger, Günther Anders (1902-1992) wrote a philosophical work which characteristic is to examine the situation of man facing the darkest events of the 20th century. Our thesis developed with a reading of the edited work supplemented by the Nachlass, aims to synthesize the unity consistency and uniqueness of his thoughts by asking a specific question : how a technical world, a world without men, could be compatible with any ethic for men without world ? To describe the shadows of the world left by a technical one, is meant to identify idealities which cover everything with an artificial obviousness. To observe the world made by men, who themselves became shadows, is like to perceive thet they are living in a environment whose they are the products. This artificail world, instead of relieving man about the nature hostility, adds other difficulties, which the technology is only sometimes able to cope with. To theorize the shadows of the world is meant to seek the specific negativity of nihilism, which is produced by technology. Our task is to show that we can refuse the nihilism as an attitude. The philosophical hypothesis defended here is metaphysical nihilism designed as prerequisite for the refusal of any other nihilistic praxis. The philosophical work of Anders allows us to conceive an occasional philosophy as a theoretical practice, pointed out as a tragic sobriety. If to break any metaphysical idea leads to disenchant the naïve victims of generalities, this theory however does not refrain us from doing metaphysics

Nuclear weapons remains in the security discourse of the United States for over 70 years. The threat of nuclear weapons changed its content several times since then. Our study examines how the nuclear threat was socially constructed and how different actors securitized the threat and to which purpose. Our Diploma thesis uses methodological framework of discourse analysis. We examine the political and social nuclear discourse in the U.S. along two levels of analysis: governmental level and nuclear disarmament level. The diploma thesis researches multiple governmental and societal sources in order to determine how different types of nuclear threat emerged within the discourse.

Full textAbstract:
A hypothetical smuggling of material suitable for a nuclear weapon is known as a threat scenario. There is a considerable effort by the U.S. government to reduce this threat by placing radiation detectors at key interdiction points around the world. These detectors provide deterrence and defense against smuggling attempts by scanning vehicles, ships, and pedestrians for threat objects. Formulating deployment strategies for these detectors within the global transportation network requires an understanding of the complex interactions between the attributes of a smuggler and the detection systems. These strategies are rooted in the continued development of novel detection systems and alarm algorithms. Radiation transport simulation provides a means for characterizing detection system response to threat scenarios. However, this task is computationally expensive with existing radiation transport codes. Furthermore, the degrees of freedom in smuggler and threat scenario attributes create a large, constantly evolving problem space. Previous research has demonstrated that decomposing the scenario into independently simulated components using Green's functions can simulate photon detector signals with coarse energy resolution. This dissertation presents a general form of this approach, applicable to a wide range of threat scenarios through physics enhancements and numerical treatments for high energy resolution photon transport, neutron transport, and time dependent transport. While each Green's function implicitly captures the full transport phase-space within each component, these new methods ensure that this information is preserved between components. As a result, detector signals produced from full forward transport simulations can be replicated within 20% while requiring multiple orders of magnitude less computation time. This capability is presented as a general threat scenario simulation platform which can efficiently model a large problem space while preserving the full radiation transport phase-space.<br>text

This thesis investigates the events leading up to and following the first North Korean nuclear test, which took place in 2006, in order to examine first, whether the test helped the North Korean regime survive, and second, how this unilateral action acted as a balance to the United States’ policy of oppression. The thesis will also attempt to shed some light on the validity of the Western International Relations (IR) theories by ascertaining the balance of threat and applying the notion of “two-level games” to the nuclear conundrum. Through the lens of these IR theories, the research described in the thesis addresses three smaller questions: (1) how did the nuclear test stabilize Pyongyang’s integrity as a balance to the threat of a potential American military attack?; (2) how was the test used as a bargaining mechanism to urge the Bush administration to shift away from its hostile stance and towards a policy of engagement?; and (3) how did the test influence the security environment of the Northeast Asian region?
Finally, the thesis considers various reasons why the nuclear deadlock in which we currently find ourselves will not be resolved in the foreseeable future, and it suggests that resolution of the nuclear stalemate can only occur once comprehensive deal-making incentives between Washington and Pyongyang are adopted.<br>Graduate<br>0615<br>lomulos@yahoo.co.kr

Full textAbstract:
Safeguards and security (S&S) systems for nuclear facilities include material control and accounting (MC&A) and a physical protection system (PPS) to protect nuclear materials from theft, sabotage and other malevolent human acts. The PPS for a facility is evaluated using probabilistic analysis of adversary paths on the basis of detection, delay, and response timelines to determine timely detection. The path analysis methodology focuses on systematic, quantitative evaluation of the physical protection component for potential external threats, and often calculates the probability that the PPS is effective (PE) in defeating an adversary who uses that attack path. By monitoring and tracking critical materials, MC&A activities provide additional protection against inside adversaries, but have been difficult to characterize in ways that are compatible with the existing path analysis methods that are used to systematically evaluate the effectiveness of a site’s protection system. This research describes and demonstrates a new method to incorporate MC&A protection elements explicitly within the existing probabilistic path analysis methodology. MC&A activities, from monitoring to inventory measurements, provide many, often recurring opportunities to determine the status of critical items, including detection of missing materials. Human reliability analysis methods are applied to determine human error probabilities to characterize the detection capabilities of MC&A activities. An object-based state machine paradigm was developed to characterize the path elements and timing of an insider theft scenario as a race against MC&A activities that can move a facility from a normal state to a heightened alert state having additional detection opportunities. This paradigm is coupled with nuclear power plant probabilistic risk assessment techniques to incorporate the evaluation of MC&A activities in the existing path analysis methodology. Event sequence diagrams describe insider paths through the PPS and also incorporate MC&A activities as path elements. This work establishes a probabilistic basis for incorporating MC&A activities explicitly within the existing path analysis methodology to extend it to address insider threats. The analysis results for this new method provide an integrated effectiveness measure for a safeguards and security system that addresses threats from both outside and inside adversaries.<br>text

The Heritage Impact Assessment (HIA) revealed that Thyspunt contains extensive heritage resources that will be destroyed as result of a Nuclear Power Station (NPS) development. Therefore this study investigates the role played by Interested and Affected Parties (I&APs) during the EIA Public Participation Process (PPP) as a tool for heritage protection. A thematic analysis of the comments submitted by I&APs during the various stages of the EIA reveal five central themes that center around the importance of heritage to the I&APs’ concerns with nuclear safety, lack of access to information, the participant’s mistrust in the EIA process and technical procedure, and recommendations for the use of cleaner and renewable energy. The study reveals the effectiveness of the EIA public participation process as a vehicle for resistance and tool for local communities to participate in a decision-making process and heritage management in South Africa. Also, it reveals how heritage can give a voice to groups and communities. Although heritage may have multiple or different meanings and communities may have differing agendas, the PPP contributed in halting the development at Thyspunt.<br>XN2020

- EN The aim of this thesis is to answer the research question of "Why did the US not conduct a military strike on Iranian nuclear facilities during the Trump presidency despite the sharp criticism of Iran's nuclear program?" The thesis presents several hypotheses that deal with the conditions for a military strike against nuclear facilities of a potential nuclear proliferator to be conducted. One such hypothesis is chosen to be confirmed or refuted in the case of US- Iran relations during Trump's presidency. The hypothesis states that Iran was able to deter the US by the threat of conventional retaliation. Methods of single case study and discourse analysis are used. The empirical part of the thesis firstly assesses whether all three steps of securitization as described by the Copenhagen school were completed. This work claims that Iranian nuclear program was indeed successfully securitized in the US during Trump's presidency. Secondly, an analysis of the components of Iranian conventional deterrence is provided. It is ascertained that Iran commanded strong enough conventional forces to be able to mount effective attacks on targets valuable to the US. All three conditions of the deterrent's credibility were also met, and Iran sufficiently communicated the threat to the US. Therefore, this thesis...

Philosophiae Doctor - PhD<br>Moss frogs are restricted to permanently moist terrestrial habitats in the south-western Cape Fold Mountains. There is a very close association between Arthroleptella distribution and Table Mountain Sandstone. Suitable habitats are generally occupied by allopatric populations of moss frogs. Comprehensive spatial sampling of moss frogs (genus Arthroleptella) in the Cape Floristic Region biodiversity hotspot yielded 192 new distribution records; 5 842 advertisement calls from 240 individual male frogs; 31 Rag-1,76 16S, 54 12S sequences and morphological measurements of 90 specimens. There are many differences in male advertisement call and genetic sequences between populations on different mountain ranges, even over small distances. A mitochondrial and nuclear gene
phylogeny of the southern African Pyxicephalidae places Natalobatrachus as the sister genus to Arthroleptella. Application of a Bayesian relaxed molecular clock model indicates that Arthroleptella arose between 20 and 39 Ma. Phylogenetic trees return two main clades within Arthroleptella: one consists of species which exhibit chirp-like calls and the second contains species with longer calls composed of a series of clicks. These two clades diverged between 19 and 22 Ma. There is a general pattern of strong phylogeographic structure with many small, isolated populations. Three species are identified within the Chirping clade and seven in the Clicking clade, including three undescribed species. This population structure is a result of the patchy distribution of suitable habitat and low vagility of the moss frogs.The distribution and speciation of moss frogs has been affected by drying and cooling climate change, changing geomorphology over the last 20 Ma and the increasing prevalence of fire over the last 5 Ma. An assessment of the threat status of each species according to IUCN criteria categorised one species as Least Concern, seven as Near Threatened, one as Vulnerable and one as Critically Endangered. The primary threats to Arthroleptella are invasive alien plants and increased fire frequencies and intensities.
