This study utilizes the Health Belief Model (HBM) to examine the factors related to the intention to participate in prevention programming for dating violence. Perceptions of susceptibility to future violence and the benefits of prevention programming appear to be the strongest predictors of participation in prevention programs. Perceptions of the severity of dating violence do not appear to be related to intentions to participate. There were no differences in intention between those reporting psychological or physical violence in their dating relationship, although some of the HBM factors were associated with a history of violence. Contrary to hypotheses, psychological and physical violence did not moderate the impact of the HBM factors on intention. Implications of these findings are discussed and recommendations for recruiting participants for primary and secondary prevention programs are offered.  相似文献

The role of small states has been largely neglected in research on the process and outcome of multilateral negotiations. Even though these states may be active in the agenda-setting processes or display a specific engagement in certain thematic aspects of negotiations, in the end game the outcome of negotiations has been perceived to be dependent on the bargaining between major powers. However, small states also have strategies at their disposal to compensate for these weaknesses. Two principal ones come to mind, prioritization or niche diplomacy, and coalition-building to join forces with like-minded states in order to draw on their resources, expertise and manpower. In the article, we compare two cases of small state coalitions in multilateral negotiations, namely the Like Minded (LM) group in the negotiations that led to the establishment of the International Criminal Court (ICC), and the Alliance of Small Island States (AOSIS) in United Nations climate negotiations. While the two coalitions resort to similar strategies, they have not been comparably successful. We will show that the ability to translate discursive power into measurable effects on outcomes ultimately depends on the institutional setting of the negotiations and the nature of the issue that coalitions are tackling.  相似文献

This study consisted of three parts to evaluate the performance of Lumicyano? on a variety of fabrics. One part assessed the impact of dye percentage (8%, 9% and 10%) on visualisation of fingermark detail and luminescent brightness in split grab marks. A 9% dye produced the highest quality detail of grab impressions with least interference from background fluorescence. The second part investigated the optimal relative humidity (RH, 75–84%) for certain fabric types using Lumicyano on split, six-series depletion fingermarks. It was concluded that the recommended RH of 80% remained the ideal cyanoacrylate fuming environment. The final and third part of this study determined the impact of sequential addition of Basic Yellow 40 (BY40) on Lumicyano compared to traditional cyanoacrylate (CA) followed with BY40 application. Results from this study demonstrated that Lumicyano on its own developed fingermarks with superior quality to Lumicyano with sequential addition of BY40 or traditional cyanoacrylate followed by BY40. Inclusion of more fabrics, donors and longer ageing periods should be explored in future studies to determine what frameworks are best for certain types of fabrics.  相似文献

Almost half of adolescents aged 11 to 14 have dated and between 10 and 30% report experiencing Teen Dating Violence (TDV). However, there are no evidence-based TDV prevention interventions designed for afterschool, community-based settings with middle-school youth, in high-risk neighborhoods. Start Strong Boston (SSB) is a model that fills all three gaps, founded on partnerships between the Boston Public Health Commission, community afterschool sites, academic experts and evaluators, and youth. Here, we describe the SSB program and discuss how this collaboration built upon successes of this peer-engaged intervention, by developing and implementing a youth participatory action research (YPAR) evaluation study of SSB. Use of the YPAR framework tested the feasibility of employing Peer Researchers in an interdisciplinary evaluation team. We describe how through participation in evaluation research, Peer Researchers improve professional and leadership skills while informing measurement and conceptualization of a program affecting their own neighborhoods. Lessons learned are presented.  相似文献

Bilateral globus pallidus necrosis is said to be characteristic of carbon monoxide (CO) poisoning. However, there has been no scientific test of this hypothesis. To examine the assertion that globus pallidus necrosis is typical of CO poisoning, this study examined autopsy cases from the King County Medical Examiner's Office (KCMEO) between 1994 and 2013. Twenty-seven cases with bilateral basal ganglia lesions were identified and examined for associated or causative disease or injury with the following results: 10 cases of drug overdose, seven heart disease, three asphyxia, two chronic ethanolism, two Huntington-like disorder, and one case each of remote trauma, rheumatic heart disease, and cerebral artery gas embolism. Additionally, review of all known cases at KCMEO of CO poisoning found no evidence of globus pallidus or basal ganglia necrosis. Thus, this study provides no support for the assertion that globus pallidus necrosis is characteristic of CO poisoning.  相似文献

This introduction to the forum section on the Multiple Streams Framework (MSF) developed by John W. Kingdon argues that the conditions under which policy making takes place today increasingly resemble the assumptions upon which Kingdon built his lens. At the same time, while the framework is extremely successful with regard to citations and has been applied in various contexts that often differ remarkably from those for which the framework was originally developed, a systematic theoretical debate about the Multiple Streams Framework is still lacking. It is the intention to spark such a debate with this forum section.  相似文献

This article suggests theoretical refinements to the multiple streams framework (MSF) that make it applicable to parliamentary systems and the decision‐making stage of the policy process. Regarding the former, the important role of political parties in parliamentary democracies is highlighted. Party policy experts are expected to be members of the policy communities in the policy stream and to promote viable policy alternatives in their respective parties, while the party leadership is concerned with adopting policies in the political stream. With regard to the latter, the introduction of a second coupling process to analyse decision making more rigorously is suggested. Moreover, the article provides operational definitions of the framework's key concepts when applied to parliamentary systems and derives a systematic set of falsifiable hypotheses for agenda‐setting and decision making in these systems, thus addressing one of the main critiques against the MSF – namely that no hypotheses can be derived from it.  相似文献

Which new parties entered national parliaments in advanced democracies over the last four decades and how did they perform after their national breakthrough? This article argues that distinguishing two types of party formation (that facilitate or complicate party institutionalisation) helps to explain why some entries flourish, while others vanish quickly from the national stage. New parties formed by individual entrepreneurs that cannot rely on ties to already organised groups are less likely to get reelected to parliament after breakthrough than rooted newcomers. This hypothesis is tested on a newly compiled dataset of new parties that entered parliaments in 17 advanced democracies from 1968 onwards. Applying multilevel analyses, the factors that shape newcomers' capacity to reenter parliament after breakthrough are assessed. Five factors have significant effects, yet affect party performance only in particular phases: both a party's electoral support at breakthrough and its operation in a system with a strong regional tier increase the likelihood of initial reelection. In contrast, a distinct programmatic profile, the permissiveness of the electoral system and easy access to free broadcasting increase a party's chance of repeated reelection. Only formation type significantly affects both phases and does so most strongly, substantiating the theoretical approach used in this article.  相似文献

In open innovation systems, capturing value through external intellectual property (IP) commercialization is an increasingly important strategy for firms to keep pace with competitive changes. However, many firms have major difficulties in creating value through external patent exploitation. To understand these challenges, this paper explores how firms manage their external patent exploitation based on a multiple case study research design with fourteen firms from the pharmaceutical and chemical industry. Adopting a desorptive capacity perspective we find four main factors influencing the firms’ management of external patent exploitation: the type of value creation, the organizational structure, the locus of initiative, and the extent of know-how transfer along with the patent. Based on these factors, three archetypes of external patent exploitation with different levels of desorptive capacity are identified. The article extends the concept of desorptive capacity and existing literature on intellectual property management in the context of open innovation. Managerial implications helping firms to implement external IP commercialization structures are discussed.  相似文献
