Abstract Recent initiatives from state and federal government agencies have helped foster the formation of community‐based watershed organizations. Although there is a great deal of enthusiasm about the potential of these organizations to enhance water quality, relatively little attention has been paid to the impacts these organizations may have on the well‐being of rural communities more generally. Assessments of effectiveness have typically focused on specific activities and accomplishments, rather than a broader range of community‐based effects. In short, we ask whether community‐based environmental management improves community as well as environment. Our research utilized a mixed‐methods design, including a statewide mail survey of all Pennsylvania watershed organizations, followed by in‐depth interviews with 28 rural watershed organizations. This sequential approach progressively explored in more detail definitions of effectiveness, including the building of rural capacity. We find watershed organizations are potentially effective mechanisms for building local leadership, enhancing the skills of rural residents, and making valuable connections with other communities, facing similar water‐resource and rural‐development issues. However, the range of issues with which local watershed organizations engage and the methods they currently utilize may eventually limit their usefulness. 相似文献

Canonical correlation has been little used and little understood, even by otherwise sophisticated analysts. An alternative approach to canonical correlation, based on a general linear multivariate model, is presented. Properties of principal component analysis are used to help explain the method. Standard computational methods for full rank canonical correlation, techniques for canonical correlation on component scores, and canonical correlation with less than full rank are discussed. They are seen to be essentially equivalent when the model equation for canonical correlation on component scores is presented. The two approaches to less than full rank situations are equivalent in some senses, but quite different in usefulness, depending on the application. An example dataset is analyzed in detail to help demonstrate the conclusions. 相似文献

Many professionals experience conflict between personal ideals about the meaning and importance of their work, and the structural limitations of the workplace. This conflict presents professionals with the challenge of how to hold true to their ideals within a non-supportive or even hostile environment. In this paper, I describe my experiences balancing my ideals about teaching, learning, and the purpose of a college education with the institutional constraints of a community college. There are three main sections in this paper. First is a discussion of the reasons I chose a career in community college teaching. The second section focuses on the institutional constraints I have encountered over the first 5 years of my career. In the third section, I explain how I have attempted to balance my ideals with the structural limitations of the college where I teach. Throughout the paper, I blend personal narrative with the relevant literature. In doing so, I intend to use my personal experience as a lens for discussing the challenges and possibilities that characterize community college teaching in general. 相似文献

A model for the assessment of exposure to Listeria monocytogenes from cold-smoked salmon consumption in France was presented in the first of this pair of articles (Pouillot et al ., 2007, Risk Analysis, 27:683–700). In the present study, the exposure model output was combined with an internationally accepted hazard characterization model, adapted to the French situation, to assess the risk of invasive listeriosis from cold-smoked salmon consumption in France in a second-order Monte Carlo simulation framework. The annual number of cases of invasive listeriosis due to cold-smoked salmon consumption in France is estimated to be 307, with a very large credible interval ([10; 12,453]), reflecting data uncertainty. This uncertainty is mainly associated with the dose-response model. Despite the significant uncertainty associated with the predictions, this model provides a scientific base for risk managers and food business operators to manage the risk linked to cold-smoked salmon contaminated with L. monocytogenes. Under the modeling assumptions, risk would be efficiently reduced through a decrease in the prevalence of L. monocytogenes or better control of the last steps of the cold chain (shorter and/or colder storage during the consumer step), whereas reduction of the initial contamination levels of the contaminated products and improvement in the first steps of the cold chain do not seem to be promising strategies. An attempt to apply the recent risk-based concept of FSO (food safety objective) on this example underlines the ambiguity in practical implementation of the risk management metrics and the need for further elaboration on these concepts. 相似文献

Abstract Objective: This study examined the prevalence of mental health disorders and their clinical correlates in a university sample of lesbian, gay, bisexual, and queer (LGBQ) students. Participants: College students at a large public university. Methods: An anonymous, voluntary survey was distributed via random e-mail generation to university students during April and May of 2011. LGBQ students were compared with their heterosexual counterparts on psychological and physical status as well as academic performance. Results: LGBQ students reported worse depressive symptoms, higher levels of perceived stress, considered themselves less attractive, and were more likely to be overweight. LGBQ students were significantly more likely to report histories of affective, substance use, and certain anxiety disorders as well as compulsive sexual behavior and compulsive buying. Conclusions: The higher rates of many psychiatric conditions among LGBQ students underscore the need for universities to provide LGBQ students a nonjudgmental environment to discuss sexual orientation and health issues. 相似文献

This paper explores the changing approach of the Chinese state to health biotechnology innovation and, in particular, the position of venture capital within that process. How has the Chinese state dealt with the opportunities and threats posed by globalisation in this field, what status has it attached to the role of venture capital in innovation and what are the implications of these actions for the role of the state? In addressing these questions, the paper begins by examining the global context of the venture capital and innovation relationship, the varied nature of VC organisation, the business models that inform the VC approach to health biotechnology innovation and the implications of these factors for the role of the state. Secondly, it explores the nature and impact of state intervention in China on the VC contribution to innovation, the particular character of the Chinese VC industry and its economic environment and the capacity of the VC sector to contribute to China’s position as a global player in health technology innovation. The paper concludes by reviewing the insights this case study provides into the problematic character of state adaptation in China to the challenges of globalisation. 相似文献

Austin Turk theorizes that places in stratification hierarchies affect police–citizen encounters by reinforcing or reversing the positional authority of police officers. To this point, however, there have been only three direct tests of the stratification portions of Turk's theory. Two examined overt conflict and all represented Turk's concepts using aggregated measures. The results are mixed. The present research adds a fourth test to the stratification and policing literatures by examining the effects of aggregated as well as disaggregated measures of stratification reinforcers and reversals on traffic ticket decisions by Boston police officers during April and May of 2001. Net of important control measures, there is no support for Turk's theory using the aggregated stratification measures employed in previous research. However, support for Turk's theory is clearly visible when viewed through the lens of some of the disaggregated stratification measures advanced for the first time in present research. We conclude that more research is needed to determine whether stratification reinforcers and reversals are among the factors affecting people in police blue and the people they police, with a sustained focus on both aggregated and disaggregated measures. 相似文献

This study tested assumptions and conclusions reached in an earlier confirmatory factor analysis (CFA) study of the social competence (SC) construct for preschool children. Two samples (total N = 408; a new Portuguese sample and one from US samples that had participated in the original study) contributed data. Seven SC indicators were tested for mean differences across age, sex, and sample. Significant sex differences were found for peer acceptance (favoring girls) and for initiating affectively neutral interactions (boys had higher rates), and the sex by sample interaction also was significant for initiating interactions (i.e., effect significant only in the Portuguese sample). In CFAs, the hypothesized structure of SC fits the data and was invariant across sample and age within sample in both measurement and structural tests. The model was invariant at the measurement level for sex within sample tests, but not at the structural level. The results replicate and extend understandings of SC reported in the original study. 相似文献

We seek to address criticisms of the concept of moral panics (MPs) by offering a hybrid model of MPs that synthesizes theory and practice of MPs research. A review of the literature on MPs from sociology, media studies and related fields shows a wide variety of usage and lack of conceptual clarity of the term ‘moral panic’. Yet there are few articles explaining how to analyze MPs. We present a theoretical clarification of MPs by addressing elements of scope, intensity and reception, to create distinction from other related theoretical concepts. To develop a working method for researching MPs, one must have an understanding of social conditions that give rise to, sustain and result in the success or failure of MPs, as well as possible lasting effects. We synthesize Cohen’s process-oriented model of MPs and Goode & Ben-Yehuda’s attribution-oriented model of MPs, creating a critical hybrid model of MPs that integrates processes and attributes. We then utilize the hybrid model to offer practical suggestions for researching and analyzing the conditions, processes and effects of MPs, in the hopes of encouraging a more rigorous research agenda for scholars of MPs. 相似文献
