William J. Chambliss (Bill) is well-known for his path-breaking theories of lawmaking and for his innovative research on state-organized crime. However, rarely discussed is the fact that his study of the original vagrancy laws marked the birth of rural critical criminology. The main objective of this article is twofold: (1) to show how Bill helped shape contemporary rural critical criminology and (2) to provide suggestions for further critical theoretical and empirical work on rural crime and social control.

The rapid disruption of tropical forests probably imperils global biodiversity more than any other contemporary phenomenon(1-3). With deforestation advancing quickly, protected areas are increasingly becoming final refuges for threatened species and natural ecosystem processes. However, many protected areas in the tropics are themselves vulnerable to human encroachment and other environmental stresses(4-9). As pressures mount, it is vital to know whether existing reserves can sustain their biodiversity. A critical constraint in addressing this question has been that data describing a broad array of biodiversity groups have been unavailable for a sufficiently large and representative sample of reserves. Here we present a uniquely comprehensive data set on changes over the past 20 to 30 years in 31 functional groups of species and 21 potential drivers of environmental change, for 60 protected areas stratified across the world's major tropical regions. Our analysis reveals great variation in reserve `health': about half of all reserves have been effective or performed passably, but the rest are experiencing an erosion of biodiversity that is often alarmingly widespread taxonomically and functionally. Habitat disruption, hunting and forest-product exploitation were the strongest predictors of declining reserve health. Crucially, environmental changes immediately outside reserves seemed nearly as important as those inside in determining their ecological fate, with changes inside reserves strongly mirroring those occurring around them. These findings suggest that tropical protected areas are often intimately linked ecologically to their surrounding habitats, and that a failure to stem broad-scale loss and degradation of such habitats could sharply increase the likelihood of serious biodiversity declines.

Desde 1945 la izquierda argentina no pudo resolver el enigma planteado por el hecho de que la clase obrera era peronista. Varios intentos teóricos fracasaron antes de que John William Cooke hiciera el suyo a mediados de los años sesenta. Influenciado por Gramsci, consideró que la clase obrera es una categoría histórica, por lo que el peronismo era la experiencia histórica de la clase obrera argentina y, como tal, revolucionario. Neutralizó el papel político de Perón convirtiéndolo en el símbolo de la identidad peronista. Por esto, la teoría de Cooke fue clave para que guerrilleros de izquierda se declararan peronistas sin que les importaran las opiniones e intenciones políticas de Perón. Las limitaciones de esa teoría quedaron expuestas cuando el general regresó a la Argentina y fue electo presidente por tercera vez.

Functional linkage between reef habitat quality and fish growth and production has remained elusive. Most current research is focused on correlative relationships between a general habitat type and presence/absence of a species, an index of species abundance, or species diversity. Such descriptive information largely ignores how reef attributes regulate reef fish abundance (density-dependent habitat selection), trophic interactions, and physiological performance (growth and condition). To determine the functional relationship between habitat quality, fish abundance, trophic interactions, and physiological performance, we are using an experimental reef system in the northeastern Gulf of Mexico where we apply advanced sensor and biochemical technologies. Our study site controls for reef attributes (size, cavity space, and reef mosaics) and focuses on the processes that regulate gag grouper (Mycteroperca microlepis) abundance, behavior and performance (growth and condition), and the availability of their pelagic prey. We combine mobile and fixed-active (fisheries) acoustics, passive acoustics, video cameras, and advanced biochemical techniques. Fisheries acoustics quantifies the abundance of pelagic prey fishes associated with the reefs and their behavior. Passive acoustics and video allow direct observation of gag and prey fish behavior and the acoustic environment, and provide a direct visual for the interpretation of fixed fisheries acoustics measurements. New application of biochemical techniques, such as Electron Transport System (ETS) assay, allow the in situ measurement of metabolic expenditure of gag and relates this back to reef attributes, gag behavior, and prey fish availability. Here, we provide an overview of our integrated technological approach for understanding and quantifying the functional relationship between reef habitat quality and one element of production – gag grouper growth on shallow coastal reefs.

Nesta tese abordamos alguns aspectos das inter-relações entre conhecimento, ética e valores dentro da atividade científica segundo as ideias do matemático-filósofo vitoriano William Clifford. O nosso tema geral coloca em jogo o envolvimento da produção, da avaliação e da transmissão de conhecimento científico com os comportamentos, as responsabilidades e os traços de caráter do investigador. Nosso objetivo é oferecer uma introdução ao pensamento e a algumas produções intelectuais de Clifford, um autor pouco familiar ao público filosófico brasileiro, bem como uma descrição comentada de seu escrito mais famoso, intitulado A Ética da Crença. Mediante esse objetivo, extraímos suas concepções a respeito das características e consequências éticas do empreendimento científico. As questões que orientam a tese são as seguintes: de que maneira a produção de conhecimento estaria condicionada à personalidade e ao comportamento ético de quem se lança àquela prática? Em que medida essa prática promove o cultivo de características pessoais socialmente desejáveis e favoráveis? Quais as conseqüências para a sociedade dessa inter-relação entre o caráter do investigador e os valores epistêmicos que estes colocam em ação e, sem os quais parece não ser possível a obtenção de conhecimento confiável?
