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

本文运用发生学的方法,揭示共同体观念的语词生成和共同体思想的理论建构。第一部分,作者指出,共同体这个语词在西方语言中源于共善和公共,具有丰富的内涵。第二部分,作者指出,共同体是古希腊罗马哲学和政治学的重要概念,在哲学形上学和伦理学的语境下,共同体与共善的关系密不可分;而在政治学的语境下,共同体是公共的名词化和实体化,共善则是建构人类社会的纲领和目标。把善提升为至善是一条哲学伦理学的理论建构通道,而把善提升为共善,则是哲学政治学的通道,与哲学伦理学的理论建构通道并行不悖。第三部分,作者指出,奥古斯丁批判地吸取了柏拉图和西塞罗的相关思想,然后以公义为纲,建构了他的理想共同体———上帝之城。奥古斯丁对共善的探究,直接导致对理想共同体的理论建构。他的理想共同体以信仰为核心,以伦理为共同体成员的守则,以秩序与和谐为共同体的特色,以普爱为共同体生存与发展的动力。  相似文献

Explicitly aimed at understanding and controlling molecular and cellular processes at the root of senescence and biological aging, regenerative medicine aspires to artificially reproduce the biological processes that enable the body to regenerate itself. This no longer involves conserving the body's state of balance by combating disease, as in clinical medicine, but rather fighting degeneration itself. From stem cell research to gene therapy to the production of replacement tissues, regenerative medicine perfectly corresponds to the logic of biomedicalization specific to postmodern society. Based on a series of 18 interviews conducted with Canadian researchers and clinicians in the field of regenerative medicine, this article seeks to understand representations of the aging body among researchers in this field. Seen from a strictly negative angle, aging is assimilated by researchers to an inevitable catastrophe that nevertheless must be combated. More closely observing the theoretical model of regenerative biology and the types of treatments developed, it can be observed, however, that this medicine of the future does not target the elderly, but rather promises youth the ability to regenerate themselves to avoid aging.  相似文献

This article contributes to understanding transformational change towards gender equality by examining the transformational change potential of a mentoring programme for women, a type of gender equality intervention both criticized and praised for its ability to bring about change. Drawing upon an empirical case study of a mentoring programme for women academics in a Dutch university, we explore three dimensions of transformational change: organizational members (i) discussing and reflecting upon gendered organizational norms and work practices; (ii) creating new narratives; and (iii) experimenting with new work practices. Our findings indicate five specific conditions that enable transformational change: cross‐mentoring, questioning what is taken for granted, repeating participation and individual stories, facilitating peer support networks and addressing and equipping all participants as change agents. We suggest that these conditions should be taken into account when (re)designing effective organizational gender equality interventions.  相似文献

乡约的诸属性及其文化原理认识   总被引:15,自引:0,他引:15  
乡约是传统社会乡民基于一定的地缘和血缘关系,为某种共同目的而设立的生活规则及组织。乡约最初形成于中国,后传播至朝鲜半岛、日本和越南,成为东亚社会共同的法律文化传统。传统中国的乡约有其时空性、价值性和法律性。乡约不是国法,但在乡民的实际生活中发挥着法的作用,是中国传统社会秩序构造链中的重要一环,其内贯一极二元主从式多样化的文化原理,与传统中国社会的结构和文化理念相契合。近代以来,乡约总体上呈现出消解的趋势,但至今仍有各种流变形式,认真对待,合理改造,必有益于中国类型法治社会的建立。  相似文献

Suppose that a group of individuals owns collectively a technology which produces a consumption good by means of a (possibly heterogeneous) input. A sharing rule associates input contributions with a vector of consumptions that are technologically feasible. We show that the set of allocations obtained by any continuous sharing rule contains Pareto efficient allocations. We also present a mechanism that implements in Nash equilibrium the Pareto efficient allocations contained in an arbitrary sharing rule. Received: 29 June 1998/Accepted: 15 November 2000  相似文献

This study examined racial differences between mistreated and abused older African American and Caucasian men. The racial and gender differences of their perpetrators were also examined. Data from a single elder abuse provider agency in the State of Illinois were analyzed. Differences with respect to physical abuse, emotional abuse, physical neglect, deprivation, confinement, and financial exploitation were examined, as were demographic characteristics and limitations of victims and abusers.  相似文献

To study the homogeneity and influences on scientists'perspectives of environmental risks, we have examined similarities and differences in risk perceptions, particularly regarding nuclear wastes, and policy preferences among 1011 scientists and engineers. We found significant differences ( p 0.05)in the patterns of beliefs among scientists from different fields of research. In contrast to physicists, chemists, and engineers, life scientists tend to: (a)perceive the greatest risks from nuclear energy and nuclear waste management; (b)perceive higher levels of overall environmental risk; (c)strongly oppose imposing risks on unconsenting individuals; and (d)prefer stronger requirements for environmental management. On some issues related to priorities among public problems and calls for government action, there are significant variations among life scientists or physical scientists. We also found that–independently of field of research–perceptions of risk and its correlates are significantly associated with the type of institution in which the scientist is employed. Scientists in universities or state and local governments tend to see the risks of nuclear energy and wastes as greater than scientists who work as business consultants, for federal organizations, or for private research laboratories. Significant differences also are found in priority given to environmental risks, the perceived proximity of environmental disaster, willingness to impose risks on an unconsenting population, and the necessity of accepting risks and sacrifices.  相似文献
