General strain theory, situational anger, and social networks: An assessment of conditioning influences

Using a random sample of university students to test general strain theory (GST), this study expanded on previous tests of strain theory in two ways. First, situational anger was measured, a construct that had not been used thus far in assessments of general strain. In addition, this research examined the role of social support networks as a conditioning influence on the effects of strain and anger on intentions to commit three types of criminal behavior (serious assault, shoplifting, and driving under the influence of alcohol [DUI]). The results provided mixed support for GST. While the link between anger and crime was confirmed, the nature of that relationship in some cases ran counter to the theory. Moreover, the evidence indicated that the role of social support networks was complex, and varied as a conditioning influence on intentions to engage in criminal activities.

Peacebuilding in East Timor

This essay analyses some of the political, economic and social challenges of East Timer's transition to independence. It scrutinizes the ethical dimensions of building peace in a territory devastated by the combined effect of Indonesia's colonial occupation and the violent militia attacks of September 1999. The most difficult task ahead does not lie in the physical rebuilding of the territory-gargantuan as it may be-but in the more intricate and long-term rehabilitation of a traumatized society. The latter involves competing Timorese factions as well as a range of international actors, including the United Nations Transitional Authority, foreign governments, business institutions and various multilateral and bilateral donors. each having their own organizational leitmotifs and policy priorities. If not managed carefully, the reconstruction process could further exacerbate existing societal tensions and complicate the starch for peace and reconciliation. The essay identifies a number of crucial components necessary to counter such risks, including the need to promote popular participation in the rebuilding process. Without the legitimacy created by strong community involvement and grassroots participation in decision making, the task of national reconstruction may well become overwhelmed by conflict.

Guilty? An explanation of the Lockerbie trial. (Case notes)

The Lockerbie Trial, concerning the explosion of Pan Am flight 103 over Lockerbie, Scotland, in 1988, took place in the Netherlands because of the fear that pre-trial publicity would make a fair trial impossible and also fears for the physical safety of the accused - case for the prosecution - application of Scottish law - report of an observer at the trial, Professor Kochler - the International Criminal Court - leave to appeal granted.

Wildlife-based tourism & increased support for nature conservation financially and otherwise: evidence from sea-turtle ecotourism at Mon Repos

The arguments of most conservationists supporting ecotourism have been based on the view that it is environmentally friendly as a resource-use and that receipts from it can counter demands to use the natural resources involved for more extractive economic purposes. But wildlife-based ecotourism can also have positive impacts in itself on the willingness of tourists to pay for wildlife conservation, strengthen the pro-conservation attitudes of tourists, and foster personal actions by them that contribute to wildlife conservation. These aspects are explored in this article on the basis of a survey of tourists visiting Mon Repos Beach near Bundaberg, Queensland, for the purpose of watching marine turtles. The results enable several of the conservation impacts of this experience on tourists to be quantified, and highlight important relationships between specific socio-economic variables and the willingness of tourists to pay for the protection of sea turtles. Furthermore, it is shown that the on-site experiences of ecotourists have positive impacts on the willingness of tourists to pay for the conservation of wildlife, and that willingness to pay is sensitive to whether or not wildlife is seen. It is suggested that in situ ecotourism is likely to be a more powerful force for fostering pro-conservation attitudes and actions among visitors than ex situ wildlife-based tourism in aquaria and zoos.

Effect of chronic clonidine treatment on transmitter release from sympathetic varicosities of the guinea-pig vas deferens

1 Previous studies have demonstrated that chronic pre-synaptic inhibition of transmitter release by morphine evokes a counter-adaptive response in the sympathetic nerve terminals that manifests itself as an increase in transmitter release during acute withdrawal. In the present study we examined the possibility that other pre-synaptically acting drugs such as clonidine also evoke a counter-adaptive response in the sympathetic nerve terminals. 2 In chronically saline treated (CST) preparations, clonidine (0.5 muM) completely abolished evoked transmitter release from sympathetic varicosities bathed in an extracellular calcium concentration ([Ca2+](o)) of 2 mM. The inhibitory effect of clonidine was reduced by increasing [Ca2+](o) from 2 to 4 mM and the stimulation frequency from 0.1 to 1 Hz. 3 The nerve terminal impulse (NTI) was not affected by concentrations of clonidine that completely abolished evoked transmitter release. 4 Sympathetic varicosities developed a tolerance to clonidine (0.5 muM) following 7-9 days of chronic exposure to clonidine. 5 Acute withdrawal of preparations following chronic clonidine treatment (CCT) resulted in a significant (P

Is bucindolol BEST? (A Key Paper Evaluation)

Carvedilol, a non-selective β-adrenoceptor blocker with ancillary properties, and metoprolol and bisoprolol, selective β1-blockers without ancillary properties, have been shown to reduce mortality and morbidity in heart failure. In the Beta-blocker Evaluation of Survival Trial (BEST), bucindolol, a non-selective β-adrenoceptor blocker with different ancillary properties to carvedilol, did not reduce overall survival in heart failure. Possible explanations for this include: more Blacks being included in the trial, bucindolol being more ‘sympatholytic’ than the other β-blockers and more advanced heart failure in BEST. Another possible explanation is that bucindolol is stimulating cardiac β2-adrenoceptors to counter the effects of inhibiting cardiac β1-adrenoceptors. Bucindolol is not the best treatment and carvedilol, metoprolol and bisoprolol should be preferred in heart failure.

The socio-religious beliefs and nature of the contemporary Vampire Subculture

The contemporary Vampire Subculture can be defined as a multi-faceted, socio-religious movement with its own distinct collective community and network of participants who share a similar belief system and customary lifestyle that reflect their concept of the vampire. The Vampire Subculture consists of individuals who profess to be 'real vampires', vampire communities of like-minded persons, 'blood-donors' who willingly allow vampires to partake of them, occult-based and mystical-orientated groups that appeal to their spirituality, the blood fetishists, and the live-action vampire role-players. In response, a Christian counter-movement of self-proclaimed 'vampire-slayers' has emerged that actively opposes the vampire subculture and its beliefs and practices. The socio-religious nature of the Vampire Subculture can be best described as a Segmented, Polycentric and Integrated Network of participants.

Cleaning symbioses from the parasites' perspective

Cleaning behaviour has generally been viewed from the cleaner or client's point of view. Few studies, however, have examined cleaning behaviour from the parasites' perspective, yet they are the equally-important third players in such associations. All three players are likely to have had their evolution affected by the association. As cleaner organisms are important predators of parasites, cleaners are likely to have an important effect on their prey. Little, however, is known of how parasites are affected by cleaning associations and the strategies that parasites use in response to cleaners. I examine here what parasites are involved in cleaning interactions, the effect cleaners have on parasites, the potential counter-adaptations that parasites have evolved against the predatory activities of cleaner organisms, the potential influence of cleaners on the life history traits of parasites, and other factors affected by cleaners. I have found that a wide range of ectoparasites from diverse habitats have been reported to interact with a wide range of cleaner organisms. Some of the life history traits of parasites are consistent with the idea that they are in response to cleaner predation. It is clear, however, that although many cleaning systems exist their ecological role is largely unexplored. This has likely been hindered by our lack of information on the parasites involved in cleaning interactions.

Conceptual modelling and ontology: Possibilities and pitfalls

Conceptual modelling is an activity undertaken during information systems development work to build a representation of selected semantics about some real-world domain. Ontological theories have been developed to account for the structure and behavior of the real world in general. In this paper, I discuss why ontological theories can be used to inform conceptual modelling research, practice, and pedagogy. I provide examples from my research to illustrate how a particular ontological theory has enabled me to improve my understanding of certain conceptual modelling practices and grammars. I describe, also, how some colleagues and I have used this theory to generate several counter-intuitive, sometimes surprising predictions about widely advocated conceptual modelling practices - predictions that subsequently were supported in empirical research we undertook. Finally, I discuss several possibilities and pitfalls I perceived to be associated with our using ontological theories to underpin research on conceptual modelling.

Apocalypse forever? International relations implications of 11 September

This is a contribution to ongoing discussion of the international relations issues raised by the terrorist attacks of 11 September 2001. It acknowledges apparent failings (of analysis or prediction) in the IR literature but then suggests the shortcomings are really the product of divergent traditions of analysis (behaviouralism, structuralism and evolutionism) which isolate different aspects of phenomena for attention. The paper then discusses the contrast between hard power and soft power - to help identify the distinctiveness of the new forms of terrorism (their non-linear objectives and the lack of proportionality involved). It concludes on an encouraging note by urging international cooperation as a solution, even in cases where the protagonists' resentments have tended to militate against conventional channels of dispute resolution.

Interfaces : educação especial & seguridade social

Com a Constituição da República Federativa do Brasil (1988), a intersetorialidade imprimiu nas políticas públicas de educação e seguridade social uma construção e uma operacionalidade mais articuladas e interdependentes. Entre as leis e portarias interministeriais, destaca-se o Programa Benefício de Prestação Continuada na Escola, que atende pessoas com deficiência de zero a dezoito anos de idade. Nesta pesquisa, questionam-se as interfaces entre as políticas públicas da educação especial e da seguridade social. São objetivos da pesquisa: analisar as interfaces das políticas públicas sociais – educação especial e seguridade social – no que se refere à garantia de direitos à educação de crianças com deficiência ou Transtornos Globais do Desenvolvimento, entre zero e cinco anos, no município de Vitória, Estado do Espírito Santo; identificar como se configuram as interdependências entre profissionais da educação especial e da seguridade social e os familiares (pais ou responsáveis) dessas crianças perante seus processos educacionais; compreender os diferentes movimentos entre as instituições de educação e da seguridade social e suas implicações para a inclusão escolar das crianças com deficiência ou Transtorno Global do Desenvolvimento; analisar como os profissionais da educação e da seguridade social lançam perspectivas para os processos de inclusão escolar e estabelecem diálogo com a família acerca da educação dessas crianças. Esta é uma pesquisa de natureza qualitativa, estudo de caso com coleta de dados empíricos e bibliográficos, na qual foram sujeitos: mães de três crianças de três Centros Municipais de Educação Infantil de Vitória; professoras da sala de atividades e de educação especial, pedagogas e diretoras; técnicos das Secretarias Municipais de Vitória: Educação, Saúde e Assistência Social e do Instituto Nacional do Seguro Social. As técnicas empregadas para coleta de dados foram a entrevista o grupo focal e o diário de itinerância. Foram procedimentos adotados para o registro dos dados a audiogravação de entrevistas e de grupos focais e anotações em diário de itinerância. Os dados foram organizados em cinco categorias de análise, produzidas por meio das narrativas dos familiares e dos profissionais participantes da pesquisa. Os conceitos de Norbert Elias, interdependência e configuração, relação de poder – estabelecidos e outsiders –, processos sociais e relação entre sociedade e Estado (balança do poder) contribuíram para compreender os dados, por serem observados nas categorias produzidas. Os resultados apontam para a fragilidade de Global do Desenvolvimento, no município de Vitória. Revelam, ainda, uma inconsistência de fluxos de referência e contrarreferência e lacunas na dimensão técnica e operativa para as interfaces das políticas públicas intersetoriais com práticas profissionais que cumpram o papel político conforme outorga a legislação federal e municipal. As considerações se ampliam para discussões entre o instituído e o instituinte – políticas públicas e práticas profissionais – que priorizem a efetivação da intersetorialidade diante das demandas do público investigado com vista à garantia dos direitos de acesso a uma educação de qualidade.

O caráter político-pedagógico dos movimentos populares de bairro da Grande São Pedro: avanços e recuos sob o imperativo da ordem capitalista

Este trabalho tem como objeto de estudo as ações organizativas dos movimentos populares de bairro, enquanto práticas político-pedagógicas. Tomamos como foco, as associações de moradores da região da Grande São Pedro. Apesar de ter ficado conhecida na década de 1980 pela situação de miséria, os moradores dessa região, historicamente perpassada pelo fenômeno da segregação socioespacial, encontraram nas adversidades motivação para a organização do movimento popular como forma de construir sua história e afirmar sua cidadania. Totalmente transformada no que tange à sua urbanização, a região ainda hoje apresenta um cenário adverso para os moradores. Nesse sentido, a importância da organização dos moradores na atualidade é fundamental para lutar contra as situações de opressão que se impõem sobre os mesmos. Entretanto, o quadro que os atuais movimentos populares de bairro desta região apresenta é de reprodução de um modelo político-cultural marcado pelo individualismo, com traços peculiares da formação social brasileira - caracterizada por práticas de centralização, dependência e clientelismo político. Deve-se registrar que apesar de também trazerem traços de lutas e resistência, a forma como atualmente acontecem, com ações em níveis imediatos, esvaziadas de conteúdo político mais amplo, sem articulação com movimentos mais abrangentes, acabam se expressando em um “associativismo individualizado”. Desta feita, reiteramos neste trabalho a necessidade de a classe trabalhadora brasileira retomar, reconstruir espaços que contribuam com a formação de lideranças, com a qualificação das bases desses movimentos, para que seus protagonistas possam consolidar uma prática político-pedagógica fundamentada na educação popular e com isso venham adensar as lutas da classe trabalhadora e somar ao projeto de construção da contra-hegemonia, visando à transformação social. Buscar-se-ia neste sentido, a consolidação de um projeto social mais igualitário, justo e verdadeiramente democrático, no qual seja possível a emancipação humana.

Modelagem e simulação de um secador intermitente de fluxos contracorrentes para frutos do cafeeiro

Este trabalho foi realizado com o objetivo de desenvolver um modelo computacional para simular a secagem de frutos café em um secador intermitente de fluxos contracorrente, empregando a linguagem de simulação EXTEND™ e o Modelo de Thompson (THOMPSON; PEART; FOSTER, 1968). Para validação do modelo desenvolvido foram utilizados dados experimentais obtidos por Silva (1991), em que foram empregados três níveis de temperatura do ar de secagem de 60, 80 e 100 °C. O modelo desenvolvido foi validado, sendo constatados desvios absolutos de 1,8% b.u e 1,1 kg e erros relativos de 11% e 1,6% na previsão dos parâmetros teor de água final e consumo de lenha, respectivamente. O modelo validado foi empregado na condução de experimentos tipo comparação de cenários. O primeiro experimento refere a alterações do ciclo operacional em que foram alterados os tempos de movimentação e de parada do fluxo da massa de grãos. E o segundo refere à alteração da configuração do secador quanto às alturas das câmaras de secagem e descanso. O ciclo operacional com os tempos de movimentação de um minuto e de parada de dezesseis minutos, para a temperatura do ar de secagem de 100 °C, proporcionou o melhor desempenho, sendo constatado tempo secagem de 12,3 h, consumo de lenha de 109,5 kg, consumo específico de energia de 7660 kJ.kg-1 de água evaporada, e capacidade de secagem de 87,86 kg.h-1. Quanto à configuração do secador, o melhor desempenho ocorreu para altura da câmara de secagem de 2,3 m usando a temperatura do ar de secagem de 100 °C, em que foram simulados tempo de secagem de 12,0 h, consumo de lenha de 106,5 kg, consumo específico de energia, de 7433 kJ.kg-1 de água evaporada, e capacidade de secagem de 90 kg.h-1. Desse modo, na condução da secagem de frutos de café em um secador intermitente de fluxos contracorrentes é recomendado o ciclo operacional com tempos de movimentação de um minuto e o de parada de dezesseis minutos, e não empregar a câmara de descanso. Essa conclusão está fundamentada em índices de desempenho do secador. Ressalta-se que não foram simulados os impactos nos parâmetros de qualidade.

The essential role of democracy in the Bush Doctrine: the invasions of Iraq and Afghanistan

Everyone knows that democracy played a role in the Bush Doctrine. What not everyone knows is that this role was essential for the doctrine to be put into operation under which the Iraq invasion was prepared and launched. We argue moreover that, even if aggressive, the Bush doctrine is compatible with the American Liberal Tradition. To demonstrate these arguments we analyze the links between democracy, security, and the US national interests as expressed in the pillars of the American foreign policy since the end of Cold War. The consequential belief of the Bush Administration on the positive effect of exporting democracy by the use of force to Afghanistan and Iraq to fight terrorism will be remarked. It will be shown, however, that in the first years of the Bush Administration, among the justifications for the military interventions in the two countries, security reasons prevailed over democratic concerns, although the latter was significantly present since the early hours after September 11. It was only when it became clear that WMDs did not exist in Iraq that the exporting of democracy as the ultimate weapon to fight terrorism grew remarkably and prevailed over security reasons to invade those rogue states. The paper uses quantitative and qualitative content analysis of the speeches of President Bush and his Secretaries of State and Defense.

Prevenção do Terrorismo versus Neoliberalismo

Ora, a prevenção do terrorismo, é o contrário de tudo isto, com um Estado cada vez maior a intervir em todo o lado, vigiando tudo e todos, aumentando os orçamentos na segurança e paz públicas, em milhares de milhões. Analisando os capitais branqueados e quem vai às privatizações para evitar o próximo atentado terrorista. Imaginem se o Estado Islâmico compra a TAP! § Now, the prevention of terrorism, is the opposite of all this, with a state increasingly to intervene everywhere, watching everything and everyone, increasing the budgets in public security and peace, in billions. Analyzing the laundered money and who is going to privatizations to prevent the next terrorist attack. Imagine if the Islamic state buys TAP!
