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

European food retailers have increased their scale and scope while concentrating sales into large stores. Strategic implications include the need for scale to compete and organisational relationships to move from supply push to demand pull retailing. Consequences are different for private label and for branded manufacturers, who must respond to the demands of retail supply chains whilst retaining control of product development. Further concentration in both sectors is likely. Consumers are more mobile, but more captive to the retailer in store. Public policy makers are challenged to find new measures of retail power and both allow for innovation and ensure equitable shopping opportunities.  相似文献

This paper documents situations where the variance inflation model for outliers has undesirable properties. The model is commonly used to accommodate outliers in a Bayesian analysis of regression and time series models. The alternative approach provided here does not suffer from these undesirable properties but gives inferences similar to those of the variance inflation model when this is appropriate. It can be used with regression, time series, and regression with correlated errors in a unified way, and adheres to the scientific principle that inference should be based on the data after obvious outliers have been discarded. Only one parameter is required for outliers; it is interpretable as the a priori willingness to remove observations from the analysis.  相似文献

All that is known about strategy and strategic planning indicates that quality is a major factor in gaining competitive advantage. It is cost effective, profitable, promotes corporate longevity and builds an important company value system. The authors argue that is too important a factor to be left solely to quality control personnel or planners and is a fundamental part of the chief executive's responsibility for the development of strategy.  相似文献

Performing some laboratory tests on site at a student health service clinic may increase efficiency and cut costs for patients. However, with the passage of the Clinical Laboratory Improvement Amendments (CLIA) of 1988, many laboratories in physician offices and clinics have shut down because of increased regulatory requirements. The personnel in one SHS laboratory found that the guidelines proposed by CLIA help assure quality care and are not prohibitive. In this article, the process of applying for and receiving a CLIA certificate in the student health clinic setting is explored.  相似文献

One of the most prominent interventions developed to protect victims in domestic abuse cases is the temporary restraining order or "TRO," the purpose of which is to restrain an alleged defendant from further harassment or abuse against a plaintiff. This report analyzes 397 restraining order petitions, and subsequent arrest and conviction data for TRO defendants from 1996 to 1998. Findings confirm that TRO petitioners report many types of abuse and while half of TRO defendants do not re-offend, a small percent of defendants are responsible for multiple police reports, arrests, and criminal violations. Outcome data are discussed for program and policy implications.  相似文献

Effective targeted and community HIV/STD prevention programs   总被引:1,自引:0,他引:1  
Community interventions and interventions targeting specific groups at risk of STDs/HIV have demonstrated significant impacts on sexual behavior, particularly condom use and safer sex. The scientific evidence suggests the factors that make these interventions particularly effective include the establishment of community, including business and CBO partnerships; maintainance of the intervention post-research funding; and buy-in by the community or target group. The modification of risky normative beliefs through the use of opinion leaders and role models, and through intervention delivery by peer educators, is an important facet of such interventions. Interventions delivered by health professionals, absent a community base, appear to be unsuccessful. Where cultures or subcultures are targeted, the close involvement of such groups in the design and delivery of messages is critical to their success. Diffusion of interventions through existing social networks further extends the intervention into the community and acts to reinforce and maintain changes in peer norms toward safer sexual behavior. The available data confirm that community or medical infrastructure-based interventions are effective in changing sexual behavior and can reach a wider range of the population than face-to-face programs if they incorporate peer educators as role models in modifying norms, and if diffusion of the intervention is integral to the design.  相似文献

Gaps in service coordination between child welfare and other child-serving agencies are well documented. This article examines the gap between the child welfare and juvenile justice systems and discusses a program, Project Confirm, designed to reduce the problems associated with this gap. Project Confirm aims to improve cooperation between juvenile justice and child welfare agencies to prevent the unnecessary detention of arrested foster children in secure facilities. The program's design is outlined, and implementation statistics and government partner perceptions of the program in its first year of operations are provided. The article also identifies future challenges to implementation and discusses the broader implications of the program. In making this appeal for coordination and collaboration among public agencies, I'm not talking about pro forma integration efforts-I'm not talking about memoranda of understanding or top-level reorganizations that have autonomous agencies vaguely reporting to a single box labeled "human services." Rather, I'm talking about the much more challenging objective of achieving real working partnerships at the front line. (Nelson, 1998, p. 6)  相似文献

Health science students, along with the health professionals they hope to become, are at increased risk for certain occupational injuries and illnesses. One of these risks is occupational exposure to blood-borne pathogens, such as human immunodeficiency virus (HIV) and hepatitis, which may result in severe illnesses or even death. Two case studies demonstrate postexposure care of exposed individuals at the University of Texas Medical Branch Student Health Services before and after policy changes and prevention strategies were strengthened in response to exposure incidents.  相似文献
