The Scottish Parliament elections of 2007 were the third to be held under the country’s mixed-member proportional system. As voters continue to adapt to the new system, we explore two aspects of its use: i) preferences for coalitions as opposed to single-party government, and ii) ticket-splitting. The two are considered together for two reasons. First, both can be seen as manifestations of a preference for multiple parties, and as a result they share a number of likely predictors in common. In empirical practice, however, we find that rather different factors predict the two variables: ticket-splitting looks to be based on strategic partisan or ideological calculation, whereas coalition attitudes are less about partisan interests and more about an overall view of the kind of policies and politics delivered by coalitions. Second, there is potential for a causal connection between our two dependent variables, and indeed we do find clear evidence of such an attitude–behaviour link: some voters appear to split their ticket precisely because they would prefer a coalition. 相似文献

Entrepreneurial strategies and tactics are often subtle and indiscrete, adding to the mystery of how one goes about being an entrepreneur, particularly within bureaucratic agencies that are often set up to constrain such behaviors. The authors use a case study of the U.S. National Aeronautics and Space Administration (NASA)'s public engagement practices to examine how entrepreneurs shift policy interpretations with administrative agencies. Findings describe three entrepreneurial strategies and tactics: (1) using one-on-one or small group meetings to connect to different audiences across organizations; (2) tying new policy interpretations to existing ones, so changes seem less radical; and, (3) positioning oneself in the middle of the action to control both narrative and progress. Conclusions discuss both practical mechanisms for shifting away from the status quo, and the theoretical contributions to a growing body of literature on strategic and tactical approaches of bureaucratic entrepreneurs in democratic systems. 相似文献

Forensic paint comparisons are generally conducted on samples which, while small relative to their source, are still visible to the unaided eye and are thus located and analyzed without great difficulty. Here we demonstrate that a more detailed examination of candidate transfer surfaces can capture materials (questioned samples), even when such traces are invisible to the unaided eye. While certain analytical details (such as layer sequence or a pure FTIR spectrum) may not be obtainable from such traces due to their size and condition, a detailed analysis of the sample characteristics that are analytically accessible may still provide sufficient analytical data to arrive at a probative result. Here we present the application of this approach to a suspected paint transfer case, involving particles of paint as small as 40 μm in size. Using a combination of stereomicroscopy, polarized light microscopy, infrared microspectroscopy, Raman microspectroscopy, and SEM/EDS, all performed on a single, subsample of the original minute particle, it was possible to demonstrate evidence of a two‐way transfer between the suspected sources. Furthermore, the transferred paint particle in one direction could be classified as automotive in nature based on a combination of polymer composition, microscopic texture, and pigment package (which included three specifically identified pigments). This work demonstrates (i) the potential for improving detection limits when searching for a questioned sample, (ii) the potential benefits of higher resolution analyses on samples that would be traditionally labeled as “sample‐size limited,” and (iii) the value of case‐specific interpretation over standardized, one‐size fits all report templates. 相似文献

Creating offender typologies has become a growing interest and a potential method of improving understanding of programming needs and potential placements. Most typological research has only explored and described potential offender types. Relatively few studies have attempted to confirm the existence of created typologies or examine how offenders in each type predict important outcomes. Utilizing a large sample (N = 37,111) of reentering male offenders from Washington State Department of Corrections, we computed both an exploratory and confirmatory latent class analysis. After the confirmation of six offender types, we examined each type’s likelihood of several recidivistic outcomes. We anticipate that the described typology will assist case management, prioritizing offender needs, optimizing treatment services, and determining sequencing of multiple treatment types. 相似文献

There is growing interest in the health correlates of people detained in police custody, and a number of innovations have been introduced to try to meet the complex needs of detainees. The implementation of Criminal Justice Liaison and Diversion (CJL&D) Services commissioned by the Department of Health in England is a substantial part of this investment. In this paper, we describe data from 858 detainees who were referred to the CJL&D service of a busy metropolitan police station in the North East of England. The detainees referred to the service had complex mental health needs, substance misuse and a range of vulnerabilities requiring specific intervention. The effective operation of these teams and how they interface with health and criminal justice systems also depend upon a number of systematic issues that emanate both from within the teams, and from external policy drivers. 相似文献

Race/ethnicity, citizenship status, and trauma, have significant impact on delinquency and crime outcomes; though the reasons for some expected and unexpected crime pathways are still unanswered. Using data from the National Longitudinal Survey of Youth 1997 (n?=?7,103), this study found the following results: no difference in the likelihood of engagement in delinquency and crime between blacks and whites; cumulative trauma increased delinquency and crime rates for all racial and ethnic groups; racial and ethnic minority groups compared to whites reported a significantly higher level of childhood trauma experiences; and native-born female immigrant groups (but not male) were more likely to engage in delinquency and crime than first-generation female immigrant groups. Implications and recommendations are set forth. 相似文献

The potential influence of violent video games on youth violence remains an issue of concern for psychologists, policymakers
and the general public. Although several prospective studies of video game violence effects have been conducted, none have
employed well validated measures of youth violence, nor considered video game violence effects in context with other influences
on youth violence such as family environment, peer delinquency, and depressive symptoms. The current study builds upon previous
research in a sample of 302 (52.3% female) mostly Hispanic youth. Results indicated that current levels of depressive symptoms
were a strong predictor of serious aggression and violence across most outcome measures. Depressive symptoms also interacted
with antisocial traits so that antisocial individuals with depressive symptoms were most inclined toward youth violence. Neither
video game violence exposure, nor television violence exposure, were prospective predictors of serious acts of youth aggression
or violence. These results are put into the context of criminological data on serious acts of violence among youth. 相似文献

Growing enthusiasm for 'Sport for development and peace' (SDP) projects around the world has created a much greater interest among critical scholars seeking to interrogate potential gains, extant limitations and challenges of using sport to advance 'development' and 'peace' in Africa. Despite this interest, the role of sport in post-conflict peace building remains poorly understood. Since peace building, as a field of study, lends itself to practical approaches that seek to address underlying sources of violent conflict, it is surprising that it has neglected to take an interest in sport, especially its grassroots models. In Africa, football (soccer) in particular has a strong appeal because of its popularity and ability to mobilise individuals and communities. Through a case study on Sierra Leone, this paper focuses on sports in a particularly prominent post-civil war UN intervention—the disarmament, demobilisation and reintegration (DDR) process—to determine how ex-youth combatants, camp administrators and caregivers perceive the role and significance of sporting activities in interim care centres (ICCS) or DDR camps. It argues that sporting experiences in ddr processes are fruitful microcosms for understanding nuanced forms of violence and healing among youth combatants during their reintegration process. 相似文献

Through case studies and empirical analysis, scholars have uncovered convincing evidence that individual donors influence lending decisions of international financial institutions (IFIs) such as the World Bank and the Asian Development Bank. Less clear are the mechanisms by which donors exert influence. Potential mechanisms are either formal or informal. Formal influence is through official decisions of the board of executive directors while informal influence covers all other channels. This paper explores the role of informal influence at the Asian Development Bank by examining the flow of funds after loans are approved. Controlling for commitments (loan approvals), are subsequent disbursements linked to the interests of the key shareholders, Japan and the U.S.? I compare these findings with results for the World Bank and consider implications for institutional reforms. 相似文献
