Research recognizes that strategic business interests can provide an important driver of private regulation, even in the absence of significant societal pressure and non‐governmental organization‐constructed demand. This article examines a range of competition and collective action‐related interests that can motivate firms to promote and adopt certification schemes. We pay particular attention to the hitherto underexplored collective action interest to safeguard common‐pool resources, upon which an industry may depend to sustain yields. Based on a case study of salmon aquaculture certification, the article argues that while the corporate motives repertoire includes strengthening competitiveness and industry reputation, safeguarding shared waters for culturing salmon is key to explaining industry commitment to and adoption of private regulation in this sector. 相似文献

We investigate the impact of policy consistency on frontline workers’ perceptions of policy meaningfulness and legitimacy. The results from an experiment involving 779 teachers indicate that policy consistency does have a positive effect on legitimacy and to a lesser extent on meaningfulness. However, the extent depends on policy content and the degree of autonomy. Overall, our findings emphasize the potential positive impact of policy consistency. Although this, to some extent, conflicts with the nature of political decision‐ and policy‐making (i.e., democratically elected governments have been mandated to change policy), our study suggests that policy consistency could be a valuable strategy for governments to strengthen successful policy implementation. This adds a new perspective to the continuing debate within policy implementation and street‐level bureaucracy research on how to account for the complex, messy and sometimes contradictory implementation of public policies. 相似文献

The immediate advantages of adolescent friendships and disadvantages of peer rejection are well documented, but there is little evidence that these effects extend into adulthood. This study tested the hypothesis that peer relationships during adolescence predict life satisfaction during middle adulthood, using data from a 30-year prospective longitudinal study. Participants included 996 (49.5 % female) 8th grade students from a community sample of Swedish youth. Self-reports of friendship and peer reports of rejection were obtained when participants were age 15. Self-reports of global life satisfaction and perceived relationship quality were collected at age 43 for women and age 48 for men. Path analyses tested a direct-effects model that examined links from adolescent friendship participation and peer rejection to middle adulthood outcomes, and a buffered-effects model that examined links from adolescent peer rejection to middle adulthood outcomes, separately for those with and without friends during adolescence. Strong support emerged for the buffered-effects model but not the direct-effects model. Adolescent friendship participation moderated associations between adolescent peer rejection and adult global life satisfaction and between adolescent peer rejection and adult perceived relationship quality such that peer rejection predicted poorer adult outcomes for youth without friends but not for youth with friends. The findings suggest that the risks of peer rejection—and benefits of friendship—extend from adolescence well into middle age. 相似文献

Public agencies have to deal with accountability demands from various societal stakeholders. Stakeholders may address their accountability demands via formal stakeholder arrangements but can also use social media for account-holding purposes. This contribution analyzes to what extent these different venues of social accountability affect the perceived relevance of societal stakeholders to agency-CEOs—their so-called “stakeholder orientation.” By combining quantitative and qualitative data, this study shows that agency-CEOs' stakeholder orientation is strongly associated with actual social media attention. In contrast, the relationship between formal stakeholder arrangements and stakeholder orientation is weak. Qualitative insights from focus group discussions suggest that the associations between social media attention and stakeholder orientation can be explained by mediatization processes within agencies and the reputational risks of social media storms. Overall, the findings support that social media attention is the most important catalyst for stakeholder orientation, rather than stakeholder arrangements. 相似文献

Drawing on multiple qualitative case studies of evidence‐based health care conducted in Sweden, Canada, Australia, and the United Kingdom, the authors systematically explore the composition, circulation, and role of codified knowledge deployed in the organizational enactment of evidence‐based practice. The article describes the “chain of codified knowledge,” which reflects the institutionalization of evidence‐based practice as organizational business as usual, and shows that it is dominated by performance standards, policies and procedures, and locally collected (improvement and audit) data. These interconnected forms of “evidence by proxy,” which are informed by research partly or indirectly, enable simplification, selective reinforcement, and contextualization of scientific knowledge. The analysis reveals the dual effects of this codification dynamic on evidence‐based practice and highlights the influence of macro‐level ideological, historical, and technological factors on the composition and circulation of codified knowledge in the organizational enactment of evidence‐based health care in different countries. 相似文献

Cobalt(II) thiocyanate-based tests are routinely used to screen cocaine products, with the formation of a blue species interpreted as a positive response. An array of other organic bases has been identified as false positives – including well-documented cocaine product adulterant lidocaine and its salt. False positives prompt continued test development, though improvements are hindered by unresolved product structures and reaction pathways. Toward greater clarity, cobalt(II) thiocyanate reactions with cocaine hydrochloride, along with lidocaine and its salt, were investigated using multiple analytical techniques. Reactions involving cocaine hydrochloride yielded glassy, amorphous blue material while reactions of lidocaine hydrochloride monohydrate produced larger, needle-like crystals whose structure was determined via single-crystal X-ray diffraction to be an ion pair (Hlidocaine+)2([Co(SCN)4]2−)·H2O. While the blue precipitate isolated from reactions involving cocaine hydrochloride was unsuitable for crystallographic structure determination, comparative ultraviolet–visible, attenuated total reflectance infrared, and Raman spectroscopic analysis – along with elemental analysis – supports that this solid is comprised of a comparable ion pair (Hcocaine+)2[Co(SCN)4]2−. Pink crystals isolated from lidocaine reaction vessels were identified as coordination compounds cis-[CoL2(SCN)2] and trans-[CoL2(SCN)2] where L = lidocaine, while pink crystals from both cocaine hydrochloride and lidocaine hydrochloride monohydrate reaction vessels were the coordination polymer trans-[Co(H2O)2(SCN)2]·H2O. The results presented herein enable reaction optimization to favor a desired product, whether ion pair or coordination species. 相似文献

The present paper examines whether there are gender differences in the associations between various dimensions of conduct problems and other problems in adolescence. Other problems studied are both of an externalizing nature (substance use) and an internalizing nature (suicidal behavior and emotional problems). Data stemmed from a large general population sample of Norwegian adolescents (N=9?342). On the basis of earlier studies, conduct problems were decomposed into three dimensions, labeled ‘Theft and vandalism’, ‘School opposition’ and ‘Covert behavior’. The first dimension includes different kinds of stealing and violence against objects, whereas the second includes school-related conduct problems of an overt aggressive kind. The last dimension reflects avoidance of arenas under adult control. Whether or not gender differences were detected, depended on the kind of conduct problems considered. We observed stronger associations between two dimensions of conduct problems, theft and vandalism and school opposition, and other problems among girls than among boys. There were no male/female differences in the associations between covert behavior and other problems. 相似文献
