Understanding the risk of biological invasions associated with particular transport pathways and source regions is critical for implementing effective biosecurity management. This may require both a model for physical connectedness between regions, and a measure of environmental similarity, so as to quantify the potential for a species to be transported from a given region and to survive at a destination region. We present an analysis of integrated biosecurity risk into Australia, based on flights and shipping data from each global geopolitical region, and an adaptation of the “range bagging” method to determine environmental matching between regions. Here, we describe global patterns of environmental matching and highlight those regions with many physical connections. We classify patterns of global invasion risk (high to low) into Australian states and territories. We validate our analysis by comparison with global presence data for 844 phytophagous insect pest species, and produce a list of high‐risk species not previously known to be present in Australia. We determined that, of the insect pest species used for validation, the species most likely to be present in Australia were those also present in geopolitical regions with high transport connectivity to Australia, and those regions that were geographically close, and had similar environments.  相似文献

Les auteurs montrent que la tentative de Pierre Bourdieu de résoudre le problème de la « domination masculine» est limitée par l'application inconséquente de son propre répertoire conceptuel, par l'emploi d'exemples empiriques périmés et par l'utilité douteuse du cas des relations sociales en Kabylie. Un rejet des catégories fondamentales (« homme », « femme ») et le recours à une conception plus nuancée de la domination seraient une approche plus prometteuse. An uneven application of his own conceptual repertoire, outdated empirical materials and the questionable utility of the example of relations in Kabylia limit Bourdieu's attempts to come to grips with “masculine domination.” A more useful approach would move beyond essentializing categories and engage with a more nuanced conception of domination.  相似文献

We describe a risk-based analytical framework for estimating traffic fatalities that combines the probability of a crash and the probability of fatality in the event of a crash. As an illustrative application, we use the methodology to explore the role of vehicle mix and vehicle prevalence on long-run fatality trends for a range of transportation growth scenarios that may be relevant to developing societies. We assume crash rates between different road users are proportional to their roadway use and estimate case fatality ratios (CFRs) for the different vehicle-vehicle and vehicle-pedestrian combinations. We find that in the absence of road safety interventions, the historical trend of initially rising and then falling fatalities observed in industrialized nations occurred only if motorization was through car ownership. In all other cases studied (scenarios dominated by scooter use, bus use, and mixed use), traffic fatalities rose monotonically. Fatalities per vehicle had a falling trend similar to that observed in historical data from industrialized nations. Regional adaptations of the model validated with local data can be used to evaluate the impacts of transportation planning and safety interventions, such as helmets, seat belts, and enforcement of traffic laws, on traffic fatalities.  相似文献

Using information gathered during fieldwork on New York lesbian and gay film festival organizations, this paper argues that scholarship on identity has not paid sufficient attention to the organizational mediation of collective identity. The shape of collective identity—how internal instabilities and diversities are accommodated, in this case—depends not only on the emergent characteristics of the “collective,” but also on the resolution of challenges particular to organizational fields. Two very differently conceived lesbian and gay festival organizations, sites at which decision making about collective identity is ongoing and self-conscious, are examined. The analysis traces how each responds to two related tasks: maintaining community legitimacy, which requires racial diversification, and surviving within an altered institutional environment. Rather than imposition from “above” or construction from “below,” the adaptive responses by organizations (to changes in both community expectations and the resource environment) transform the collective identity formulations reaching public visibility. Earlier versions of this paper were presented at the Colloquium Series of the Center for Lesbian and Gay Studies, City University of New York, 1995, and at the Annual Meeting of the American Sociological Association, Washington, DC, 1995.  相似文献

Evidence of self reported morbidity from two household surveys, carried out in London and Manchester is discussed. These data permitted intra-urban and interurban comparisons of patterns of morbidity reporting. The morbidity reported in response to two different instruments is compared: for the items used in the British General Household Survey (GHS) Health Section, and for the Nottingham Health Profile. The results from the London survey are analysed in more detail to examine the nature of self reported morbidity in the inner and outer city. The influence of interviewer effects is analysed, showing that the GHS items were more liable to interviewer effect than the NHP. The type and number of illnesses reported in response in response to the GHS also appeared to vary between the inner and outer London samples: The NHP appeared to be less affected by interviewer effects and variation in interpretation.  相似文献

This paper examines how the Chinese state's prenatal health care campaigns of the early 1950s attempted to redefine women's social and political roles. The replacement of local midwifing practices with a uniform birthing method in order to radically reduce infant and mother mortality entailed complex ramifications regarding the relationship of women vis-a-vis the state. Campaigns involved demonizing "traditional" midwifing, promoting a statistical vision of female reproductivity and children as national resources, and the isolation of individual mothers as directly responsible to the state for managing reproduction for the national interest. In sum, a physiological definition of gender was used to open women's bodies to state management. Utopic visions of painless childbirth and of the socialist nation as a giant new family were used to promote participation in grassroots campaigns, but the sources also point to forms of local resistance to the micro-level reorganization of power these campaigns intended.  相似文献

Conclusion The early formulations of reproduction theory fail to grasp uneven educational development because of a reliance on a mechanical, base/ superstructure model of social organization. Unlike neo-Weberian models which attempt to sever the necessary connection between the existence of public education and commodity production, reproduction theory emphasizes the correspondence of public education and the capitalist economy. But this correspondence does not adequately conceptualize the unity of form and content in capitalist relations of production. As a causal model it implies that economic relations develop in the absence of their institutional counterparts. The weight of economic needs then calls institutional reform into play. Such a model reduces historical development to the movement of pure forms.The early formulations of reproduction theory confuse abstract and historical levels of analysis. They also fail to adequately grasp social units. Capitalism is a world economy in which production extends well beyond national boundaries, yet in which labor power is reproduced on the whole by national states. Without an analysis of relations among nations, uneven educational development is unintelligible.The patterns of educational development seen in Ireland and Upper Canada resulted from the colonial status of these countries which made educational reform appear a potential solution to imperialist struggles. Educational reforms blocked in England because of class struggles and sectarian divisions could be invoked in the colonial situation by virtue of the relative independence of the colonial state. These reforms, however, embodied structural features peculiar to capitalist relations of production. Precocious educational development in these cases results from the heightened development of the colonial state in relation to the colonial political economy.Public education does not, one would think obviously, eliminate class relations. Rather, public educational reform is a mode of reformulating class relations by the state. This reformulation changes the appearance of class relations but not their basis. Public education is not compensation for the loss of liberty political subjects endure by consenting to be ruled by the state; it is more usefully seen as one way in which the state administers class relations. As such, it reproduces class struggles in displaced forms. Such displaced struggles are seen by neo-Weberian writers as constellations of interests, but one should not lose sight of the structural origins of such interests.While reproduction theory has presented serious critiques of liberal theory and has stressed the historically specific character of public education, it has embodied functionalist assumptions which limit its ability to come to grips with concrete historical development. To escape these assumptions it is necessary to reject a base/ superstructure model and to seek rather to understand the expanded reproduction of the essential social forms of capitalist society.  相似文献

This paper investigates differential customer racial reaction to negative and positive publicity related to professional athletes. In terms of negative publicity, it analyzes the effect of mention in the Mitchell Report on the price of baseball cards. In regards to positive publicity, it considers the impact of having been identified as a member of the United States Olympic or national team. After controlling for player productivity with performance statistics, the effects of being mentioned in the Mitchell Report are isolated within regression analysis to draw conclusions concerning customer racial attitudes toward the steroids scandal. Similar analysis is conducted to see the impact of being seen as a baseball representative of the United States. Regression results are consistent with the conclusion that negative publicity devalues the cards of nonWhite players but not of White players. Positive publicity, however, increases the value of a player's card regardless of ethnicity.  相似文献
