Despite diverse understandings of cosmopolitanism, most authors agree that cosmopolitans espouse a broadly defined disposition of ‘openness’ toward others, people, things and experiences whose origin is non‐local. It is argued that such an attitude is expressed by an emotional and ethical commitment towards universalism, selflessness, worldliness and communitarianism, and that such values should be identifiable in the practices, attitudes and identifications of individuals. By using data generated through qualitative focus group research, this paper extends the development of Lamont and Aksartova's (2002 ) category of ‘ordinary cosmopolitanism’. The participants in this study saw themselves as beneficiaries of an increasingly interconnected world, and they generally expressed cosmopolitan sentiments by referring to easily accepted opportunities associated with globalisation (eg. travel, cuisine, music) rather than the more difficult aspects of openness such as showing hospitality to strangers, or accepting human interest ahead of perceived national interests. Their positive views were counterbalanced, however, by sentiments of ‘dilution of national culture’ and ‘culture loss’. We argue that cosmopolitanism is a set of structurally grounded, discursive resources available to social actors which is variably deployed to deal with issues like cultural diversity, the global, and otherness. Ironically these discourses, which are the basis of the everyday accounts we describe, mirror academic debates on globalisation, suggesting the immersion of theorists in these discursive webs of meaning that structure responses to things global.  相似文献

The paper makes an appraisal of the most appropriate sampling point for situations where a single sample must be used to estimate the mean flow of a continuous stream during a set time interval. Taking ‘optimal’ to mean the point at which the estimation error variance is minimised, optimal sampling locations are obtained for constant, linear and exponential flow rates when the process variogram is assumed linear or exponential. Numerical results illustrate the significance of failing to sample at the optimal point.  相似文献

After discussing ways in which the concept of vulnerability is applied to children in psychology and sociology. It is argued that many of these may arise from the mistaken concretisation of essentialising concepts which have sometimes thereby become barriers to, rather than facilitators of, sociological understanding. Fieldwork is presented and analysed concerning the interactions of some London children, and their characterisations of themselves and others, in a variety of home, school and other settings. It is suggested that situations in which children are present often do generate 'vulnerability' in all participants not only in the children. In classrooms and elsewhere the attribution and reality of vulnerability moves rapidly between persons as situations develop and change.  相似文献

A tenure committee first votes on whether to hire a candidate; if it does, it receives an informative performance signal, and then votes on whether to tenure the candidate; rejection at either stage returns the committee to a candidate pool, endogenising the value of the outside option. A candidate’s fate depends only on the behaviour of two ‘weather-vane’ committee members. Committee members may vote against favoured candidates if the weather-vane is opposed; enthusiastic assessments by one of these weather-vanes may harm a candidate’s chances by increasing others’ thresholds for hiring him; sunk time costs may lead voters who voted against hiring to vote for tenuring him, even after a poor probationary performance. For two member committees that are patient and perceptive, the optimal voting rule is a (weak) majority at the hiring stage and unanimity at the tenure stage; when such committees are impatient or imperceptive, the double (weak) majority rule is optimal. Perversely, the performance of a patient, imperceptive committee improves as its perceptiveness further declines. Consistent with practice, falling threshold rules are not optimal. Results on optimal voting rules are also presented in limit cases as committee members’ beliefs become more correlated. Finally, we compare the model to a discrete-time European options model.  相似文献

A robust estimation procedure for the bifurcating autoregressive model in cell lineage studies is proposed. The method is illustrated by application to a real data set and is compared with least squares estimates in a small simulation study.  相似文献

A two-phase study employed a combination ofqualitative and quantitative methodology to studyabsenteeism in a complex, hospital setting. The primaryfocus was to identify the bases of employees' beliefs about what is acceptable and expected in termsof absence behavior. Through a series of employeeinterviews, two different absence cultures wereidentified. We found evidence that employees' normativeperceptions were influenced by their prior personalabsence, and by the average level of absence within boththeir immediate work group and the absence culture towhich they belonged. Perceived norms were also shown to predict future individual absence (totaldays absent) 1 year later. Theoretical and practicalimplications of this research were discussed.  相似文献

This paper argues that the identity of social work as a form of professional practice within Europe is a timely matter for contemporary debate. Economic and political moves in Europe towards integration have created the possibility of establishing an identity which could both incorporate a range of diverse activities and also create a form of practice that is distinct. This article will address the emerging concept of social exclusion as a potential focus for social work professional practice in a changing global setting. It will be argued that the concept is one that can incorporate the broad range of practice in social work in a manner that could have similar meaning for all the different practitioners involved.  相似文献

The global controversy regarding the use of genetically modified (GM) crops has proved to be a challenge for "science-based" risk assessments. Although risk analysis incorporates societal perspectives in decision making over these crops, it is largely predicated on contrasts between "expert" and "lay" perspectives. The overall objective of this study is to explore the role for farmers' knowledge, and their decade-long experience with herbicide-tolerant (HT) canola, in the risk analysis of GM crops. From 2002 to 2003, data were collected using interviews ( n = 15) and mail surveys ( n = 370) with farmers from Manitoba and across Canada. The main benefits associated with HT canola were management oriented and included easier weed control, herbicide rotation, and better weed control, whereas the main risks were more diverse and included market harm, technology use agreements (TUAs), and increased seed costs. Benefits and risks were inversely related, and the salient factor influencing risk was farmer experiences with HT canola volunteers, followed by small farm size and duration using HT canola. These HT volunteers were reported by 38% of farmers, from both internal (e.g., seedbank, farm machinery, etc.) and external (e.g., wind, seed contamination, etc.) sources, and were found to persist over time. Farmer knowledge is a reliable and rich source of information regarding the efficacy of HT crops, demonstrating that individual experiences are important to risk perception. The socioeconomic nature of most risks combined with the continuing "farm income crisis" in North America demonstrates the need for a more holistic and inclusive approach to risk assessment associated with HT crops and, indeed, with all new agricultural technology.  相似文献
