Pakistan is geographically situated between China and the Gulf. In order to balance its strategic position against the major security threat of India, Pakistan formed a special and stable strategic alliance with China against common threats since the period of the cold war even though the two countries have neither a political ideology nor political system in common. On the other hand Pakistan established another special relation with Saudi Arabia on the basis of Islamic identity. With its expanding economic capacity, China proposed a project by the name of "new silk road economic corridor" with the intention of expanding and multiplying trade routes with the Middle East and Europe. Within this framework Pakistan is expected to expand the role of an alternative land route that connects the Gulf and China for use if unfavorable emergencies occur in the Malacca route. However, the continuous political uncertainty in Afghanistan after the pullout of US-NATO fighting forces at the end of 2014 and sporadic outbreaks of terrorist acts by Pakistan Taliban in Pakistan have increased China's anxiety regarding Uyghur issues at home. Avoiding military options for the moment, China is trying to find ways to play an active role in the security issues of Afghanistan with help from Pakistan if available. On the other hand, it is noteworthy that the Pakistani government formed in the general election of 2008 completed its full term and transferred authority to the newly elected government in 2013, something never observed before in Pakistan's history. Coincidently, in Afghanistan the presidential election was carried out peacefully in 2014 in spite of the Taliban threat. Although it is too early to make any definite conclusion, constitutional processes, in spite of their defects, reflected to some extent wishes for normal life of the people of Pakistan and Afghanistan who were disgusted with weak governance and the prevalence of terrorism.

2014年6月のイスラーム国(以下ISIS)のメディアへの華々しい登場以降、米国政治を規定する主要な要因の1つとして「恐怖心」がかつてない程の重要性を帯びてきている。本稿では政治心理学的な分析手法を援用しつつ、ISISが何よりも「テロ攻撃集団」としていかに「恐怖心」を醸成するための洗練された戦略を実践しているか、またそれが統計的には圧倒的に中東現地のムスリム一般住民を標的にしており、本来的にS.ハンティントン的な「西欧文明に敵対するイスラーム」という問題を内包していないにもかかわらず、米国エスタブリッシュメントによる他者への「恐怖心」によって如何に本質が曲解されて「ムスリム排斥」のような情緒的な政治主張に向かわせているかの契機を分析する。筆者は論稿中でマキャベリから以降最近に至るまでの政治学関係の議論を渉猟しつつ、「恐怖心」をめぐる問題が「テロル」との関係においていかに扱われてきたかを再検討し、西欧のメディアにおける「テロ集団」としてのISISの登場が政治学的な観点から提起している問題の新しさと古さを跡付けようとする。同時に現在の米国社会を覆っているイスラモフォビアの情緒的反応についてもその淵源が古くかつ政治的に根深い問題から発していることを指摘している。本論稿の分析は直接的にはISISによって政治的な雰囲気が大きく変容するなかで大統領選挙の年を迎えている米国の国内政治を扱うものであるが、ここでの議論は「アラブの春」以降のシリア危機に発する難民問題に直面している欧州(EU)や、2015年11月のパリのテロ多発事件以降緊迫した雰囲気に覆われているフランスの政治状況にも通底しており、その意味では偶々2014年にISIS によって惹起されたとはいえそれ自体が自律的な展開の契機を内包する現代社会の政治的な抑圧的システムのグローバルな拡大と拡散に警鐘を鳴らそうとするものである。

La expansión de las tecnologías de la información y las comunicaciones (TIC) ha traído muchas ventajas, pero también algunos peligros. Son frecuentes hoy en día las noticias sobre delitos relacionados con las TIC. Se usa a menudo el término cibercrimen y el de ciberterrorismo pero, ¿realmente son una amenaza para la sociedad?. Este trabajo realiza un análisis del cibercrimen y el ciberterrorismo. Para ello se hace un estudio en profundidad desde distintos puntos de vista. En primer lugar se analizan varios aspectos básicos de la materia: el contexto en el que se desarrollan estas actividades, el ciberespacio y sus características, las ventajas que tiene el cibercrimen respecto a la delincuencia tradicional, características y ejemplos de ciberterrorismo y la importancia de la protección de las infraestructuras críticas. Luego se realiza un estudio del mundo del cibercrimen, en el cual se muestran los distintos tipos de cibercriminales, los actos delictivos, herramientas y técnicas más habituales usadas por el cibercrimen, la web profunda y la criptomoneda; se indican asimismo varios de los grupos criminales más conocidos y algunas de sus acciones, y se realiza un estudio de las consecuencias económicas del cibercrimen. Finalmente se hace un repaso a los medios legales que distintos países y organizaciones han establecido para combatir estos hechos delictivos. Para ello se analizan estrategias de seguridad de distinto tipo aprobadas en multitud de países de todo el mundo y los grupos operativos de respuesta (tanto los de tipo policial como los CSIRT/CERT), además de la legislación publicada para poder perseguir el cibercrimen y el ciberterrorismo, con especial atención a la legislación española. De esta manera, tras la lectura de este Proyecto se puede tener una visión global completa del mundo de la ciberdelincuencia y el ciberterrorismo. ABSTRACT. The expansion of Information and Communications Technology (ITC) has brought many benefits, but also some dangers. It is very usual nowadays to see news about ITC-related crimes. Terms like cyber crime and cyber terrorism are usually used but, are they really a big threat for our society?. This work analyzes cyber crime and cyber terrorism. To achieve it, a deep research under different points of view is made. First, basic aspects of the topic are analyzed: the context where these activities are carried out, cyber space and its features, benefits for cyber criminals with respect to traditional crime, characteristics and relevant examples of cyber terrorism, and importance of critical infrastructures protection. Then, a study about the world of cyber crime is made, analyzing the typology of different kinds of cyber criminals, the most common criminal acts, tools and techniques used by cyber crime, and the deep web and cryptocurrency. Some of the most known criminal groups and their activities are also explored, and the economic consequences of cyber crime are assessed. Finally, there is a review of the legal means used by countries and organizations to fight against these unlawful acts; this includes the analysis of several types of security strategies approved by countries all around the world, operational response groups (including law enforcement and CSIRT/CERT) and legislation to fight cyber crime and cyber terrorism, with special emphasis on Spanish legal rules. This way, a global, complete view of the world around cyber crime and cyber terrorism can be obtained after reading this work.

Esta Tesis Doctoral tiene como principal objetivo el obtener una cadena de tratamientos seguros de aguas seriados que nos permita asegurar la calidad de las aguas para consumo humano en caso de emergencias, de tal forma que se minimicen los efectos de acciones hostiles, como sabotajes o actos terroristas, desastres naturales, etc y buscar soluciones adecuadas para garantizar en este caso la salud. Las plantas de tratamientos de aguas existentes comercialmente no aseguran dicha calidad y la documentación sobre el tema presenta vacíos de conocimiento, contradicciones entre resultados de investigaciones o insostenibilidad de conclusiones de las mismas. Estas carencias nos permiten determinar los aspectos a tratar durante la investigación. Por ello, este objetivo se concretó en tres acciones: Investigar sobre rendimientos de plantas convencionales en eliminación de microorganismos y productos tóxicos y peligrosos. Introducir mejoras que garanticen el rendimiento de las plantas convencionales. Investigar sobre la conveniencia de complementar las instalaciones existentes buscando seguridad y garantía sanitaria. Y se desarrollaron tres líneas de investigación: LI 1 “Inorgánicos”: Investigación sobre la eliminación de los metales boro, cobre y molibdeno mediante procesos de intercambio iónico y de coagulaciónfloculación- decantación. LI 2 “Compuestos Orgánicos Volátiles”: Investigación sobre la eliminación de los compuestos orgánicos 1,1 dicloroetano, 1,2 dicloroetano, clorobenceno, 1,3 dicloropropeno y hexacloro 1,3 butadieno mediante procesos de carbón activo granular y de oxidación avanzada. LI 3 “Plantas portátiles”: Investigación sobre plantas existentes portátiles para verificar su rendimiento teórico y proponer mejoras. Estas líneas de investigación se desarrollaron tanto en el nivel teórico como en el empírico, bien sea en laboratorio como en campo. A lo largo del documento se demuestra que las principales fuentes de contaminación, salvo la degradación de yacimientos naturales, proceden de la actividad humana (efluentes industriales y agrícolas, aguas residuales y actividades beligerantes) que provocan un amplio espectro de enfermedades por lo que dificultan tanto la definición de la fuente como la anticipada detección de la enfermedad. Las principales conclusiones que se obtuvieron están relacionadas con el rendimiento de eliminación de los parámetros tras la aplicación de los procesos y plantas de tratamiento de aguas anteriormente reseñadas. Sin embargo, el verdadero elemento designador de originalidad de esta Tesis Doctoral, tal como se ha reseñado arriba, radica en la definición de un sistema seriado de procesos de tratamiento de aguas que asegura la calidad en caso de emergencia. Éste se define en el siguiente orden: pretratamiento, oxidación, coagulación-floculación-decantación, filtración por arena, intercambio iónico, carbón activo granular, microfiltración, radiación UV, ósmosis inversa, radiación UV y cloración final. The main objective of this Thesis is to obtain a chain of stepwise safe water treatments that allow us to ensure the quality of water for human consumption in case of emergencies, so that the effects of hostile actions, such as sabotage or terrorism, natural disasters, etc. and seek appropriate solutions in this case to ensure health. The existing commercial water treatment plants do not ensure quality, and the documentation on the subject presents knowledge gaps or contradictions. These gaps allow us to determine the issues to be discussed during the investigation. Therefore, this objective was manifested in three actions: Researching yields in commercial plants and microorganisms, or toxic and dangerous products removal. Improvements to ensure the performance of conventional plants. Inquire about the advisability of implementing existing facilities for safety and health guarantee. And three lines of research are developed: LI 1 “Inorganic elements”: Research removing metals iron, copper and molybdenum by ion exchange processes and coagulation-flocculation-decantation. LI 2 “Volatile Organic Compounds”: Research removing organic compounds 1,1 dichloroethane, 1,2 dichloroethane, chlorobenzene, 1,3-dichloropropene and 1,3-butadiene hexachloro through processes of granular activated carbon and advanced oxidation. LI 3 “Compact Water Treatment Plants”: Research on existing packaged plants to verify theoretical performance and suggest improvements. These lines of research are developed both theoretically and empirically, both in the laboratory and in the field. Throughout the document, it is evident that the main sources of pollution, other than the degradation of natural deposits, come from human activity (industrial and agricultural effluents, sewage and belligerent activities) which cause a broad spectrum of diseases which hamper both the definition of the source and the early detection of the disease. The main conclusions drawn are related to both the removal efficiency parameters after application of processes and treatment plants outlined above water. However, the real designator of originality of this thesis, such as outlined above, lies in the definition of a serial system water treatment processes assuring quality in case of emergency. This is defined in the following order: pretreatment, oxidation, coagulation-flocculation-sedimentation, sand filtration, ion exchange, granular activated carbon, microfiltration, UV radiation, reverse osmosis, UV radiation and final chlorination.

Attempted hydrogen–deuterium exchange of trimethyloxonium ion, (CH3)3O+ with excess of 1:1 2HF/SbF5 superacid at −30°C over a period of 30 days showed no exchange. Theoretical calculations at the MP2/6–31G** level are in accord with the lack of hydrogen–deuterium exchange in the methyl group of the (CH3)3O+ cation as protonation (protosolvation) prefers the oxygen lone pair of electrons, instead of a C—H bond. Methylation of aromatics with the (CH3)3O+CF3SO3− in CF3SO3H and 2CF3SO3H:B(O3SCF3)3 was also studied. Whereas in triflic acid no alkylation was observed, in triflatoboric acid, a powerful superacid, alkylation takes place, indicating protolytic activation of the trimethyloxonium ion.

Perhaps the most enduring debate in reptile systematics has involved the giant Galápagos tortoises (Geochelone nigra), whose origins and systematic relationships captivated Charles Darwin and remain unresolved to this day. Here we report a phylogenetic reconstruction based on mitochondrial DNA sequences from Galápagos tortoises and Geochelone from mainland South America and Africa. The closest living relative to the Galápagos tortoise is not among the larger-bodied tortoises of South America but is the relatively small-bodied Geochelone chilensis, or Chaco tortoise. The split between G. chilensis and the Galápagos lineage probably occurred 6 to 12 million years ago, before the origin of the oldest extant Galápagos island. Our data suggest that the four named southern subspecies on the largest island, Isabela, are not distinct genetic units, whereas a genetically distinct northernmost Isabela subspecies is probably the result of a separate colonization. Most unexpectedly, the lone survivor of the abingdoni subspecies from Pinta Island (“Lonesome George”) is very closely related to tortoises from San Cristóbal and Española, the islands farthest from the island of Pinta. To rule out a possible recent transplant of Lonesome George, we sequenced DNA from three tortoises collected on Pinta in 1906. They have sequences identical to Lonesome George, consistent with his being the last survivor of his subspecies. This finding may provide guidance in finding a mate for Lonesome George, who so far has failed to reproduce.

O presente trabalho propõe um processo para auxiliar a tarefa de implantação de controles de Cadeia Logística Segura para a importação e exportação de cargas conteinerizadas, transportadas pelo modal rodoviário. Está em consonância com a legislação brasileira atual, no que se refere à Receita Federal do Brasil e demais Órgãos Anuentes. Além disso, inclui, também, as novas diretrizes do Programa Brasileiro de Operador Econômico Autorizado que teve seu início na primeira quinzena de Dezembro de 2014, bem como os aspectos principais do quadro SAFE, da Organização Mundial das Aduanas (OMA) e do programa americano Customs-Trade Partnership Against Terrorism (C-TPAT). O processo proposto no trabalho contempla a instrumentação dos controles e seus principais pontos de integração de dados, estágio em que grande parte dos operadores econômicos atuais se encontra. A proposta justifica-se pela complexidade dos processos de cadeias logísticas, sua importância para o comércio exterior e, portanto, para a economia do país, que exigem um aperfeiçoamento constante para atender à competitividade crescente dos mercados, controlar e gerenciar riscos e incertezas dos tempos da globalização. A metodologia do trabalho de pesquisa constou de estudos sobre o significado de cadeia logística segura, legislações e normatizações existentes, principais tecnologias utilizadas no Brasil e no mundo e suas estratégias de integração de sistemas, com enfoque em alguns projetos de gestão já existentes no país. O porto de Santos foi tomado como campo principal de pesquisa. O trabalho evidenciou a importância da presença de três características fundamentais em um processo de cadeia logística segura: ser instrumentado, integrado e inteligente. Considera-se que, a partir do processo proposto, será possível aumentar o grau de inteligência de uma cadeia logística, de forma a gerenciar e mitigar os potenciais riscos de forma mais racional.

In the past ten plus years, several million national guard and reserve component military personnel have been deployed in support of the global war on terrorism. Tens of thousands of those personnel also serve as full-time law enforcement officers in police and sheriff's offices around the country. Life as a law enforcement officer is tough enough, but when combined with the psychological baggage brought on by months of war, reintegrating into civilian life and the role of a law enforcement officer can be extremely difficult. This article discusses a reintegration program specifically for law enforcement agencies that is designed to promote long-term psychological and social health in combat veteran officers. The program's costs are offset by the many assets (leadership, tactical training, etc.) these men and women bring to the department. By committing to the long-term successful reintegration of these individuals, departments enhance their own forces and improve community safety.

O lobo-guará é uma espécie de ampla distribuição na América do Sul, tendo no Brasil sua maior área de ocorrência. No entanto, as modificações das áreas naturais principalmente destinadas à agropecuária tornam a espécie vulnerável à extinção. A investigação objetivou conhecer em larga escala a área de distribuição potencial gerada por atributos ambientais favoráveis e áreas adequadas à sua ocorrência nos biomas brasileiros e investigar como a espécie responde à estrutura da paisagem, avaliando os efeitos de ambientes modificados pelo homem na sua ecologia espacial, nos padrões de atividade e na movimentação. Modelos de distribuição de espécie foram gerados pelo Maxent, utilizando uma base de pontos de localização de presença a partir de 2000 para o Cerrado (Ce), Pantanal (Pa), Mata Atlântica (MA) e Pampas (Pp) e um conjunto de onze variáveis ambientais não correlacionadas (topográficas, climáticas e paisagísticas). Para análises de ecologia espacial, das atividades e de movimentação, utilizou-se localizações de telemetria (GPS) de animais habitantes de áreas protegidas (AP), e indivíduos em paisagens modificados (AM). Análises de áreas de vida (AV) foram realizadas utilizando o estimador AKDE e associadas com classificação da paisagem local. Os modelos de distribuição do lobo-guará apresentaram uma área de distribuição potencial de 78% do total dos biomas. Apesar de possuírem grandes proporções de áreas adequadas (Ce, 90%; Pa, 93%; MA, 65% e Pp, 6%), somente um pequeno percentual (4,4% do Ce e 4,7% da MA) possui adequabilidade ambiental acima de 50%. Dos atributos que favorecem sua presença, a altitude (para todos os biomas), a precipitação (Ce e Pa), diferenças de temperatura e uso e cobertura do solo (Ma e Pp) foram os mais importantes. Em nível local, animais apresentaram média de AV de 90Km2 em AP e 41Km2 em AM, uma diferença significativa (p<0,01) com áreas diretamente proporcionais ao percentual de áreas naturais na paisagem. Ainda, apesar dos padrões regulares de atividade não mostrarem grandes mudanças, o período de repouso foi significativamente maior (p<0,01) entre os animais AM (46% do dia) que em animais AP (25% do dia). Lobos-guarás de AP e AM não apresentaram grandes diferenças no deslocamento diário com média geral de 14km caminhados por dia, com comprimentos de passos de 1Km. Diferenças no comprimento de passo foram relacionadas à composição da diversidade de contato de classes da paisagem com a proporção de ambientes naturais no passo (quanto maior as variáveis, maior o passo). Passos menores refletem menor persistência de movimento interferindo no deslocamento diário. Com os resultados desse estudo identificou-se a MA e Pa muito importantes, mas o Ce como bioma mais adequado à espécie. Foram encontrados indícios de que a estrutura de suas AV, o uso da paisagem, as atividades e movimentação são afetados pela paisagem modificada. Isso pode comprometer a viabilidade populacional, interferindo na presença em uma área e refletindo no seu potencial de distribuição. As estratégias de manejo de uso do solo, e a recuperação e conexão de áreas adequadas são urgentes e necessárias para que o lobo-guará permaneça presente e funcional nas paisagens dos biomas brasileiros.

This capstone examines the civil liberties of the modern terrorist and explicates the right to freedom of speech for terrorist organizations and their use of the internet. Terrorist organizations use the internet to promote ideas, recruit members, organize the flow of information, and coordinate actions. During the war on terror the US Patriot Act became law allowing for U.S. government censorship and surveillance of internet traffic and many believe these acts are a threat to civil liberties. Terrorist organizations have the right to express their views, however unpopular, and censoring or restricting web sites diminishes civil liberties for all, which democracies and liberal societies are founded upon.

The timber wolf has been eradicated from most of its North American range, but in recent decades has been recovering. The Timber Wolf Preservation Society (TWPS) was founded to assist in the reestablishment of wolf populations in Wisconsin. The public education mission of the TWPS is a key element in increasing human tolerance of wolves. This capstone summarizes principles of wolf ecology and the care of captive mammals. Challenges faced by the TWPS, including more effective board management practices and the need for a strategic plan, are also identified. Suggestions and recommendations for improving the TWPS administration, board governance and organizational growth are presented to allow the TWPS to become sustainable and continue to contribute to wolf recovery efforts in Wisconsin.

The United Sates was founded on the principles of freedom. Events in recent history have threatened the freedoms we as individuals enjoy. Notably, changes to government legislation and policies regarding access to environmentally sensitive information following September 11, 2001, are troubling. The government has struggled with a difficult balancing act. The public has the right of access to information, yet, information some view as sensitive or dangerous must be kept out of the hands of terrorists. This project examines and discusses the information access debate within the United States and how to best provide the public environmentally sensitive information.

In response to 9/11, the U.S. launched airstrikes in Afghanistan against al Qaeda to diminish its ability to conduct future attacks. Next, the U.S. turned its attention to Iraq. A series of problems and missteps there subsequently created an opportunity for al Qaeda to evolve, aligning itself with active insurgencies and other terrorist groups around the world. This paper identifies the largely preemptive strategies employed by the U.S. and analyzes how those efforts positively and negatively impacted the War on Terror. While some significant gains were made, the results show that al Qaeda remains a threat to the international community and demands more effective U.S. and international counter-radicalization strategies, including diplomacy and aid, to curb its global appeal.
Ammonia removal using activated carbons: effect of the surface chemistry in dry and moist conditions
Resumo:
The effect of surface chemistry (nature and amount of oxygen groups) in the removal of ammonia was studied using a modified resin-based activated carbon. NH3 breakthrough column experiments show that the modification of the original activated carbon with nitric acid, that is, the incorporation of oxygen surface groups, highly improves the adsorption behavior at room temperature. Apparently, there is a linear relationship between the total adsorption capacity and the amount of the more acidic and less stable oxygen surface groups. Similar experiments using moist air clearly show that the effect of humidity highly depends on the surface chemistry of the carbon used. Moisture highly improves the adsorption behavior for samples with a low concentration of oxygen functionalities, probably due to the preferential adsorption of ammonia via dissolution into water. On the contrary, moisture exhibits a small effect on samples with a rich surface chemistry due to the preferential adsorption pathway via Brønsted and Lewis acid centers from the carbon surface. FTIR analyses of the exhausted oxidized samples confirm both the formation of NH4+ species interacting with the Brønsted acid sites, together with the presence of NH3 species coordinated, through the lone pair electron, to Lewis acid sites on the graphene layers.
