Invasive species risk maps provide broad guidance on where to allocate resources for pest monitoring and regulation, but they often present individual risk components (such as climatic suitability, host abundance, or introduction potential) as independent entities. These independent risk components are integrated using various multicriteria analysis techniques that typically require prior knowledge of the risk components’ importance. Such information is often nonexistent for many invasive pests. This study proposes a new approach for building integrated risk maps using the principle of a multiattribute efficient frontier and analyzing the partial order of elements of a risk map as distributed in multidimensional criteria space. The integrated risks are estimated as subsequent multiattribute frontiers in dimensions of individual risk criteria. We demonstrate the approach with the example of Agrilus biguttatus Fabricius, a high‐risk pest that may threaten North American oak forests in the near future. Drawing on U.S. and Canadian data, we compare the performance of the multiattribute ranking against a multicriteria linear weighted averaging technique in the presence of uncertainties, using the concept of robustness from info‐gap decision theory. The results show major geographic hotspots where the consideration of tradeoffs between multiple risk components changes integrated risk rankings. Both methods delineate similar geographical regions of high and low risks. Overall, aggregation based on a delineation of multiattribute efficient frontiers can be a useful tool to prioritize risks for anticipated invasive pests, which usually have an extremely poor prior knowledge base. 相似文献

Abstract This article presents evidence and argument dealing with partisan political identification among white ethnic groups. Recently, numerous political commentators and analysts have argued that the ethnic-labor component of the New Deal coalition is in the midst of collapse and decay, and that white ethnics are re-aligning with the Republican Party. Through an analysis of public opinion data gathered between 1936 and 1974, the partisan re-alignment theory is critically examined. The data show little or no support for the idea that Catholic and Jewish ethnics are identifying more closely with the Republican Party. Data show that degree of identification with the Democrats is nearly the same in 1974 as it was in 1936. 相似文献

This paper presents an exploration of the concept of hope in clinical and developmental contexts. Traditionally, psychoanalytic theory has emphasized pathological aspects of development and, not surprisingly, the subject of hope has been neglected. Although the therapist's hope and how it impacts on the treatment is within the purview of the paper, the predominant focus is on the patient's hope and the dimension of mutuality in the treatment that fosters it. A case example is provided to illustrate the unfreezing (Winnicott, 1954) of unconscious hope in a phase of treatment I call the phoenix juncture. Connections are drawn between the capacity for reflection and hope. The paper concludes with a discussion of a view of hope as problematic or regressive, along with a selective literature review. 相似文献

On a local level, creating and sustaining community schools requires leadership from local government, schools, businesses, and nonprofit organizations. These groups must provide the fuel and direction to move the community school strategy forward along a common vision and with strategic methods for financing. At the federal level, it must continue to build constituency for community schools if it is to succeed, although the community school movement has made great strides in recent years. There is not now a coherent federal framework to support the community school vision. The proposed Full Services Community Schools legislation would build a national constituency and legislate key principles advocated by the Coalition for Community Schools: developing districtwide community school strategies, focusing on results, and improving coordination of funding streams. 相似文献

This case study explores the first decade (2002–2012) of the California Senior Leaders Program (CSLP), including participants' creation of a formal advocacy group, the California Senior Leaders Alliance. Grounded in concerns with ageism and invisibility, the CSLP provides recognition and support for diverse California elders engaged in community building and social justice work. This study employs qualitative analysis of data from participant interviews, event evaluations, program documents, video footage, and participant observation. Findings show emotional, learning, and networking benefits for participants, intergenerational influences, collective capacity and coalition building, and contributions to policy. Program challenges are described, and future directions discussed. 相似文献

This critical inquiry explores the question: What are the ethical implications of promoting normative ideals for healthy aging, such as volunteerism and civic engagement, that specifically emphasize productivity and contribution? In this paper, we identify the values and ethical standpoints embedded in the discourse promoting volunteerism and productive aging and then describe what this suggests about how older adults are viewed, valued and judged. More specifically, we argue that older adult volunteering has at times been framed in a manner that dually suggests: a) lifelong productivity is a necessary condition to be a good old person; and b) lifelong productivity is a necessary condition to be a good old citizen. We then demonstrate that the current promotion of older adult volunteerism and productive aging is ethically troubling because: 1) it fails to capture the full potential of the self — and in particular, the aging self; and 2) it grounds justice in a narrowly defined and unfair distributive scheme. An alternative model of aging is then presented based on equal regard for all persons insofar as this approach is inclusive of the diversity of older adults and aging processes, and policy implications are discussed. 相似文献

The basic thesis of this paper is that effective use of therapeutic metaphor can provide a holding environment within which the client can both address and recontextualize clinical issues. The use of therapeutic metaphor can serve to bolster the empathic connection between therapist and client, providing the client with a new feeling of being understood, in part through a new use of language. Therapeutic metaphor is also particularly well-suited to promoting dialectical understanding and analysis of everyday problems in living. The inner edge of possibility is a construct that illustrates the link between the clinical efficacy and structure of therapeutic metaphor. 相似文献
