ABSTRACT

The ‘policy entrepreneur’ concept arises from the Multiple Streams’ theory of agenda setting in Policy Studies. Through conceptual stretching’, the concept is extended to global policy dynamics. Unlike ‘advocacy networks’ and ‘norm entrepreneurs’, the discussion addresses the strategies of ‘insider’ or ‘near-governmental’ non-state actors. The analysis advances the policy entrepreneur concept in three directions. First, the discussion develops the transnational dimensions of this activity through a case study of International Crisis Group. Second, rather than focusing on charismatic individuals, the discussion emphasizes the importance of organizational resources and reputations for policy entrepreneurship and access into international policy communities. Organizations maintain momentum behind policy solutions and pressures for change over the long term when individuals retire or depart for other positions. Third, the discussion outlines four distinct entrepreneur strategies and techniques that both individuals and organizations cultivate and deploy to enhance their power and persuasion in global policy processes and politics.  相似文献

Spatial variation in soil inorganic nitrogen across an arid urban ecosystem   总被引:4,自引:1,他引:3  
We explored variations in inorganic soil nitrogen (N) concentrations across metropolitan Phoenix, Arizona, and the surrounding desert using a probability-based synoptic survey. Data were examined using spatial statistics on the entire region, as well as for the desert and urban sites separately. Concentrations of both NO3-N and NH4-N were markedly higher and more heterogeneous amongst urban compared to desert soils. Regional variation in soil NO3-N concentration was best explained by latitude, land use history, population density, along with percent cover of impervious surfaces and lawn, whereas soil NH4-N concentrations were related to only latitude and population density. Within the urban area, patterns in both soil NO3-N and NH4-N were best predicted by elevation, population density and type of irrigation in the surrounding neighborhood. Spatial autocorrelation of soil NO3-N concentrations explained 49% of variation among desert sites but was absent between urban sites. We suggest that inorganic soil N concentrations are controlled by a number of ‘local’ or ‘neighborhood’ human-related drivers in the city, rather than factors related to an urban-rural gradient.  相似文献

Many explanations have been given as to why men batter. Rarely are deep unconscious intrapsychic processes identified as contributing reasons. One way that violent men may use their partner to fill emotional needs is through the primitive defense of projective identification. Projective identification may be invoked by men to induce the other partner to carry split off threatening parts of the self that are too anxiety provoking to retain. The occurrence of projective identification could therefore be an important intrapsychic and interpersonal dynamic that contributes to the escalation of tension prior to the violent episode.  相似文献

Many studies have provided evidence that, in birds, inexperienced breeders have a lower probability of breeding successfully. This is often explained by lack of skills and knowledge, and sometimes late laying dates in the first breeding attempt. There is growing evidence that in many species with deferred reproduction, some prebreeders attend breeding places, acquire territories and form pairs. Several behavioural tactics assumed to be associated with territory acquisition have been described in different species. These tactics may influence the probability of recruiting in the breeding segment of the population, age of first breeding, and reproductive success in the first breeding attempt. Here we addressed the influence of behaviour ('squatting') during the prebreeding period on demographic parameters (survival and recruitment probability) in a long-lived colonial seabird species: the kittiwake. We also investigated the influence of behaviour on reproductive trajectory. Squatters have a higher survival and recruitment probability, and a higher probability of breeding successfully in the first breeding attempt in all age-classes where this category is represented. The influence of behaviour is mainly expressed in the first reproduction. However, there is a relationship between breeding success in the first occasion and subsequent occasions. The influence of breeding success in the first breeding attempt on the rest of the trajectory may indirectly reflect the influence of behaviour on breeding success in the first occasion. The shape of the reproductive trajectory is influenced by behaviour and age of first breeding. There is substantial individual variation from the mean reproductive trajectory, which is accounted for by heterogeneity in performance among individuals in the first attempt, but there is no evidence of individual heterogeneity in the rate of change over time in performance in subsequent breeding occasions  相似文献

WOMEN ATHLETES AS FALSELY ACCUSED DEVIANTS: Managing the Lesbian Stigma   总被引:1,自引:0,他引:1  
As the behavior of women athletes is often interpreted to violate gender norms, women athletes are frequently devalued and stigmatized. The present study examines the manner in which such devaluation and stigmatization impact on women athletes and how these athletes manage the lesbian label attached to their sport participation. In-depth telephone interviews were conducted with 24 intercollegiate athletes from three Division I universities. Processes underlying athletes' responses parallel Becker's construction of the "falsely accused deviant" and Goffman's conceptualization of "stigma management." Factors leading to false accusation of lesbianism are discussed, as well as the various mechanisms utilized by athletes to manage the lesbian label.  相似文献
