Les auteurs analysent l'effet de la directive européenne relative à l'information et à la consultation des travailleurs sur les pratiques participatives en entreprise au Royaume‐Uni et en Irlande. Dans une analyse conceptuelle et empirique, qui fait appel à la théorie des jeux, ils formulent trois hypothèses explicatives, qu'ils cherchent à vérifier avec des données qualitatives recueillies auprès de seize entreprises. La démonstration permet de comprendre pourquoi la coopération, gage de gains mutuels, n'est pas la solution qui l'emporte dans les pays examinés, et elle nous en dit un peu plus sur l'effet des normes sur la gestion participative dans les économies de marché libérales. 相似文献
In recent years there has been increased interest in outcome‐based social policy‐making and management. The UK has been in the forefront of this movement but similar movements have been identified internationally. This interest in outcome‐based decision‐making has been given particular impetus through the ‘results’‐based movement in evaluation and performance management since the 1980s, which has increased in scope over time, slowly changing its emphasis from cost reduction and measuring outputs to measuring outcomes. This change has been widely welcomed by policymakers, practitioners and academics. However, there is evidence that the reality is often rather less than the rhetoric. Moreover, the ‘attribution problem’ of attributing changes in outcomes to specific social policies has remained a major issue. The conceptual solution of constructing ‘cause‐and‐effect’ models, imported from the policy evaluation field, has only recently become common for operationalising these models. This article outlines the evolution of interest in outcome‐based social policy‐making up to recent times and the growing realization of the importance of the attribution problem. It then outlines both how the ‘cause‐and‐effect’ policy modelling approach can partially tackle the attribution problem, but also its inherent limitations. Lastly, the article uses several case studies in current UK social policy‐making to demonstrate the potential importance of the reasoning embedded within cause‐and‐effect models but also the dangers in policy‐making which adopts this approach without understanding its conceptual basis or in fields where it is inappropriate, given the current state of our knowledge of social policy systems. 相似文献
The Australian farmer faces important and interconnected management challenges on both the economic and ecological fronts. To confront these challenges effectively, farmers would be well advised to constitute themselves as a professional body along the lines of the Bar Association. Making farming a professional activity in this sense would provide a number of important benefits and advantages. It would facilitate the provision and delivery of the needed educational resources for economic and ecological land management, and help farmers avoid the pressures of heavy‐handed government centralism. At the same time, such professionalism would encourage more efficient use of sector resources by minimising the need for direct political lobbying and intra‐farm group competition for membership. As a professional body, farmers could hope for increased public standing and the economic clout that would come from having control over the supply of skilled land managers. 相似文献
Nowadays, the majority of human beings live in urban ecosystems, with this proportion expected to continue increasing in the future. With the growing importance of urban rat-associated issues (e.g. damages to urban infrastructures, costs of rat-control programs, rat-associated health risks), it is becoming indispensable to fill the identified gaps in knowledge on the urban brown rat regarding, among others, its density, home range, genetic structure, and infectious status. In this context, live-trapping is a crucial prerequisite to any scientific investigation. This paper assesses the main constraints and challenges regarding the urban field and describes the major steps to be considered when planning research on urban rats. The primary challenges are i) the characterization of the urban experimental unit; ii) the choice of a trapping design: the use of live-trapping in capture-mark-recapture design, in association with modern statistics, is highly recommended to answer ecological questions (although these methods, mostly developed in natural ecosystems, need to be implemented for the urban field); iii) the potential ethical considerations with regard to animal welfare and field-worker safety; iv) the building of mutually-beneficial collaborations with city stakeholders, pest control professionals, and citizens. Emphasis must be put on communication to the public and education of field-workers. One major need of modern urban rat research is a peer-validated field methodology allowing reproducibility, repeatability, and inference from urban field studies and enabling researchers to answer long-standing key questions about urban rat ecology. 相似文献
We compare the relative influence of different celebrity endorser attributes on respondents’ intentions to donate to a fictitious charity. The celebrity endorser attributes we modeled are expertise, admirability, likeability, trustworthiness, and attractiveness. We examine the moderating effects of audience sex, and general attitudes toward charities. Finally, we examined the mediating effects of perceived endorser fit with the endorsed charity. Our results find that endorser expertise and admirability are significant predictors of audience donation intentions. Audience general attitudes toward charities are a significant moderator of the influence of endorser expertise and admirability on donation intentions. We discuss the implications of our findings for researchers and practitioners.
Relatively little attention has been paid to the use and importance of labels used by men who have sex with men to describe insertive or receptive sexual behavior during intercourse. This study examines sexual self‐labels, sexual behavior, HIV transmission risk, and psychological functioning among 205 HIV‐seropositive men who have sex with men. The majority of participants (88%) identified as a “top, “ a “bottom, “ or “versatile. “ Tops were more likely to engage in insertive anal intercourse than bottoms, and bottoms were more likely to engage in receptive anal intercourse than tops, with versatiles reporting intermediate rates of both behaviors. Although the results suggest preliminary evidence regarding the predictive utility of self‐labels, sexual behaviors of self‐label groups were greatly overlapping. Differences were found among self‐label groups in gay self‐identification, internalized homophobia, sexual sensation seeking, and anxiety. Results suggest an added value in assessing self‐labels in addition to asking about sexual behavior. 相似文献
