Regional resilience: Pre-service teacher preparation to teach in the bush

This paper reports on the outcomes of a two year ALTC Competitive Research and Development Project that aimed to "Develop Strategies at the Pre-Service Level to Address Critical Teacher Attraction and Retention Issues in Australian Rural, Regional and Remote Schools". As well as developing a ‘training framework’ and teaching guides to increase the capacity and credibility of four universities to prepare educators who might venture out of the metropolitan area to teach, data were gathered from pre-service and graduate teachers to analyse regional resilience. It was found that there was a strong likelihood to participate in a regional practicum and stay in a non-metropolitan community once they graduated from university if they had a positive attitude to regional Western Australia either through a family connection or previous experience. Recommendations from this study emphasise the importance of having pre-service students participate in positive regional experiences early in their university study.

Lineage delimitation and description of nine new species of bush frogs (Anura: Raorchestes, Rhacophoridae) from the Western Ghats Escarpment

Bush frogs of the genus Raorchestes are distributed mainly in the Western Ghats Escarpment of Peninsular India. The inventory of species in this genus is incomplete and there is ambiguity in the systematic status of species recognized by morphological criteria. To address the dual problem of taxon sampling and systematic uncertainty in bush frogs, we used a large-scale spatial sampling design, explicitly incorporating the geographic and ecological heterogeneity of the Western Ghats. We then used a hierarchical multi-criteria approach by combining mitochondrial phylogeny, genetic distance, geographic range, morphology and advertisement call to delimit bush frog lineages. Our analyses revealed the existence of a large number of new lineages with varying levels of genetic divergence. Here, we provide diagnoses and descriptions for nine lineages that exhibit divergence across multiple axes. The discovery of new lineages that exhibit high divergence across wide ranges of elevation and across the major massifs highlights the large gaps in historical sampling. These discoveries underscore the significance of addressing inadequate knowledge of species distribution, namely the ``Wallacean shortfall'', in addressing the problem of taxon sampling and unknown diversity in tropical hotspots. A biogeographically informed sampling and analytical approach was critical in detecting and delineating lineages in a consistent manner across the genus. Through increased taxon sampling, we were also able to discern a number of well-supported sub-clades that were either unresolved or absent in earlier phylogenetic reconstructions and identify a number of shallow divergent lineages which require further examination for assessment of their taxonomic status.

Os efeitos políticos da securitização internacional do terrorismo pós-11/09: o caso da Organização de Cooperação de Xangai

Esta dissertação trata do que se entende como terrorismo após os atentados de setembro de 2001, seja como lógica de ação ou como método de ação. A partir desta data, o terrorismo alcançou enorme projeção e passou a figurar como tema central tanto na imprensa cotidiana quanto em reuniões internacionais de cúpula. O fenômeno era, muitas vezes, historicamente circunscrito às nações que enfrentavam esse problema. Após o Onze de Setembro, o debate expandiu-se e as políticas, e a propaganda, antiterroristas incidiram sobre a sociedade, modificando comportamentos individuais e coletivos. A associação entre Islamismo e terrorismo foi frequente e a Guerra Contra ao Terror (GCT), promovida pela política externa norte-americana de George W. Bush, contribuiu para difundir uma percepção do terrorismo como uma lógica de ação afeita à violência em si. Isso contrasta com a percepção quanto a grupos terroristas de momentos históricos anteriores, cujo recurso ao terrorismo era compreendido como método de ação com valor instrumental para alcançar objetivos políticos diversos, como a emancipação nacional e a desestabilização de regimes políticos estabelecidos. O estudo de caso da Organização de Xangai (OCX) visa demonstrar que a identificação entre terrorismo e Islã leva ao equívoco de compreender os grupos terroristas contemporâneos islâmicos, com lógicas próprias, como uma fenômeno só o que leva à imprecisão de atribuir ao terrorismo o caráter de primeiro fenômeno macro-securitizado. Este breve histórico da ascensão do terrorismo na agenda política contemporânea, mediante a análise do processo securitizador tanto na GCT quanto na Organização de Cooperação de Xangai, serve como referência para as análises contidas no trabalho que o leitor tem em mãos, uma vez que o sentido atribuído ao terrorismo só pode ser entendido em termos dos atores políticos envolvidos na sua definição e no contexto em qual o fazem. Na OCX, o verificou-se o entendimento do terrorismo como método de ação de grupos separatistas, o que não corresponde à ideia do terrorismo como lógica de ação contida na GCT.

墨西哥湾Alaminos Canyon、Bush Hill冷泉碳酸盐岩有机地球化学与沉积环境

本文通过对墨西哥湾Bush Hill 的5个冷泉碳酸盐岩样品和Alaminos Canyon 的1个冷泉碳酸盐岩样品的总有机质含量、可溶有机质含量、饱和烃、芳烃、脂肪酸、δ13C组成分布特征和部分地球化学参数的研究，探讨了冷泉碳酸盐岩中有机质来源、成熟度和沉积环境。 Bush Hill的冷泉碳酸盐岩样品的总有机碳为0.78-9.02%，可溶有机质含量5.77-65.06mg/g。总有机碳达9.02%的GC-B样品高碳数正构烷烃奇偶优势明显，存在荧蒽、芘和苝系列化合物，表明该样品有陆源物质的输入，并明显受深部渗漏原油的影响，其中烷烃的δ13C为-27.64～-32.36‰，正构脂肪酸δ13C为-26.52～-39.99‰，与现代菌藻类及下伏油气藏的δ13C值（-27～-31‰）相似，表明样品中的有机质主体可能来源于深部油气藏。其余4个Bush Hill冷泉碳酸盐岩样品和1个Alaminos Canyon冷泉碳酸盐岩样品正构烷烃的低碳优势明显，而奇偶优势不明显，低碳数分布的环己烷和长链烷基苯，以及三芳甾烷和甲基三芳甾烷的存在，推断这些样品的母质以菌藻类来源为主。 所有分析样品的甾烷成熟度参数C29ββ/(ββ+αα)为0.28-0.40，C2920S/(20S + 20R)为0.42-0.61、及C20-C21三芳孕甾烷TA(Ⅰ)/C26-C28三芳甾烷TA(Ⅱ)为0.49都说明样品的有机质成熟度较低,。 AC深水区AC-E样品UCM隆起不明显，Bush Hill浅水区样品（GC-B、GC-D、GC-F、GC-G，GC-H）UCM隆起均十分明显，这种隆起的形成是因为正烷烃、甚至五环三萜烷遭受生物降解。被微生物降解的正构烷烃与未被降解的环烷烃和支链烷烃等形成不能被溶解的复杂混合物（UCM）。因此，UCM隆起通常被认为是有机质遭受生物降解最直接的证据。深水区AC-E和Bush Hill浅水区GC-F样品中芴、氧芴和硫芴之间的丰度关系为硫芴﹥芴﹥氧芴，表明其为弱氧化-弱还原的沉积环境。具有较负碳同位素组成（-63.95‰ ~ -50.48‰）的异构/反异构脂肪酸是硫酸盐还原细菌的典型生物标志化合物，进一步证实冷泉碳酸盐岩的形成与甲烷缺氧氧化作用有关。 关键词：墨西哥湾 冷泉碳酸盐岩 有机质组成分布 单体烃碳同位素 沉积环境

A fruit in the hand or two in the bush? Divergent risk preferences in chimpanzees and bonobos.

Human and non-human animals tend to avoid risky prospects. If such patterns of economic choice are adaptive, risk preferences should reflect the typical decision-making environments faced by organisms. However, this approach has not been widely used to examine the risk sensitivity in closely related species with different ecologies. Here, we experimentally examined risk-sensitive behaviour in chimpanzees (Pan troglodytes) and bonobos (Pan paniscus), closely related species whose distinct ecologies are thought to be the major selective force shaping their unique behavioural repertoires. Because chimpanzees exploit riskier food sources in the wild, we predicted that they would exhibit greater tolerance for risk in choices about food. Results confirmed this prediction: chimpanzees significantly preferred the risky option, whereas bonobos preferred the fixed option. These results provide a relatively rare example of risk-prone behaviour in the context of gains and show how ecological pressures can sculpt economic decision making.

Super-villains of the "real world": the political use of the characterization of villains in Chistopher Nolan's "Dark Knight Trilogy"

It is almost a tradition that celluloid (or digital) villains are represented with some characteristics that remind us the real political enemies of the producer country of the film, or even enemies within the country according to the particular ideology that sustains the film. The case of Christopher Nolan The Dark Knight trilogy, analyzed here, is representative of this trend for two reasons. First, because it gets marked by political radicalization conducted by the US government after the attack of September 11, 2001. Secondly, because it offers a profuse gallery of villains who are outside the circle of friends as the new doctrine “either with us or against us” opened by George Bush for the XXI century. This gallery includes from the very terrorists who justify the War on Terror (Ra's al Ghul, the Joker), to the “radical left” (Bane, Talia al Ghul) including liberal politicians (Harvey Dent), and corrupt that take advantage of the softness of the law to commit crimes with impunity (Dr. Crane, the Scarecrow).

'American hegemony after September 11: Allies, rivals and contradictions'

11 September heralded and provided a pretext for a more aggressive but increasingly contradictory American hegemony. Some of the consequences are contrary to the United States' own interests. Its new doctrine of 'preemptive strike' against other sovereign states encourages similarly belligerent behaviour by other governments, and yet more terrorism by nonstate actors, the very threats which were to be eradicated by a re-asserted US hegemony. This essay focuses on three partly overlapping themes: different strategies towards allies - multilateral and unilateral; different forms of power - civil and military; and different ideologies of globalisation - neoliberal and neo-conservative. It argues that while US policy may oscillate between such poles, it often combines the different elements. The overall strategy of the Bush administration is best characterised as unilateral multilateralism. The main issue for US hegemonists is the ways in which their hegemony might best be exercised, maintained and strengthened vis à vis allies and rivals. But for a safer, more democratic world, the choice does not lie between one faction of US hegemonists and another: we need other alternatives such as cosmopolitan democracy and a genuine internationalist movement which would give it some much-needed substance.

The Future of Preventive Wars: The Case of Iraq

Eight years have past since the devastating September 11 attacks, and the USA has engaged in two wars in the name of uprooting global ‘terrorism’ and providing security to American citizens. The Bush administration bequeathed a legacy of two ongoing wars and growing threats emerging from ‘terrorist’ acts. This article analyses the future of the preventive war doctrine, formulated by the Bush administration, under international law. The article thus explores whether the preventive war doctrine has the potential to set a customary precedence, or whether it merely constitutes a breach of international law.
