This article presents and tests a knowledge and technology transfer framework in a quadruple helix environment, from an actor perspective. The Canadian forest products industry provides a unique opportunity for data collection through case studies as it is an industry built on a triple bottom line, which is managed for sustainable progress. By confronting the new framework to 31 professionals, we highlight the role and challenges faced by each helix. Several factors such as culture, time horizon management and the adaption of theory to practice appear to be determinant to improve technology transfer. We see in our work an important contribution to the generalization of knowledge and technology transfer processes in a quadruple helix environment.  相似文献

The current study examines the relationship between military service and criminal behavior of veterans, both combat and non-combat, compared to non-veterans using a nationally representative sample of inmates. Specifically, this study examines the relationship between veteran status and crime type among inmates in state and federal institutions. While the relationship between military service and criminal behavior of veterans has received considerable attention, many have failed to differentiate between veterans who have seen combat versus those who have not. Therefore, a subsample of veterans who experienced combat during their military service is examined to better inform our understanding how combat experience might influence this relationship. Multiple counterfactual methods, including propensity score matching, were used on data from the Survey of Inmates in State and Federal Correctional Facilities, 2004. Some significant differences exist in the types of offenses committed based on veteran status and combat experience, but in some cases contrary to expectations. Veterans were more likely to have committed a violent offense, but less likely to have committed drug offenses; whereas, combat veterans were more likely to commit a drug offense and less likely to commit a violent offense than non-combat veterans. Policy implications and recommendations for future research are explored.  相似文献

DNA traces found at crime scenes and DNA records held in databases have already helped the police to solve numerous investigations into specific crimes. The police clearly benefit from the use of forensic science at an operational (i.e. case) level. This paper focuses on the use of forensic DNA at a strategic level: its use in the study of patterns of criminal behaviour. The usual sources of information for this type of research are recorded crime data, self-report studies and victimization surveys. However, as our review will show, these data sources cannot provide a complete picture of crime. We therefore propose an alternative approach to criminological research that takes into account DNA databases and has the potential to augment current methods and extend the existing knowledge beyond known offenders. The use of DNA databases has an important advantage for criminological research: it is possible to link offences committed by the same individual, whether the offender’s identity is known or not. By making a one-on-one comparison of police data with the corresponding DNA data, not only can co-offenders be studied, but a larger network of offenders connected to each other can also be analysed, even if their identity is unknown to the police.  相似文献

Despite the mounting scholarly interest in processes of institutional change in international organizations, still very little is known about how and when such evolutionary dynamics occur. This article hopes to contribute to this young, yet growing body of literature by process-tracing the changes that have occurred in the institutional setup of the International Energy Agency (IEA). Founded during the first oil crisis of 1973–74, the IEA has had to deal with major environmental changes over its lifetime. In response, the agency has diversified away from its original raison d’être, namely managing an emergency oil sharing mechanism, to become a more proactive policy adviser guiding its member governments toward sustainable energy economies. The article seeks to explain the observed patterns of change and inertia, using a theoretic paradigm that builds on theories of “new institutionalism.” The paper argues that the agency’s institutional flexibility can only be fully explained by taking into account a combination of factors: (1) the member states’ choices, in particular the impulses of the G8-members of the IEA; (2) path dependency, especially the institutional link with the Organization for Economic Cooperation and Development (OECD); and (3) agency by the secretariat and the executive bureau of the IEA.  相似文献

The schools-as-communities perspective provides a popular explanation for school-disruptive behavior, stating that interpersonal bonding at school and feelings of school belonging prevent misconduct. In this article, we build on this perspective in three ways. First, we test whether the preventive influence of school belonging acts at the individual or school level. Secondly, we test whether a distinction should be made between the different actors with whom students bond at school, by assessing whether perceived teacher support, school belonging, and peer attachment relate differently to school misconduct. Lastly, the present study investigates whether the associations of bonding with teachers, peers and the school with school misconduct differ by socio-ethnic school context. Multilevel analyses were performed on data from the Flemish Educational Assessment. The sample consisted of 11,872 students (51.4% female) in 85 schools, most of whom were natives (88.8%), with immigrants (11.2%) mostly having Turkish or Moroccan backgrounds (both about 30% of immigrants in the sample), and others Southern-European (16%), Eastern-European (8%), North-African (5%), or other (17%) backgrounds. Results showed that the students’ individual feelings of bonding with peers, teachers and school associate with school misconduct, rather than the overall school cohesion. Results further showed that, while higher perceived teacher support and school belonging related to less school misconduct, higher peer attachment was associated with higher rates of school misconduct. No differences were found by socio-ethnic context. Implications are discussed.  相似文献

This article extends the study of regulatory enforcement on three levels. First, it separates enforcement style elements during inspections and sanction decision‐making work, creating a more realistic measurement. Second, it focuses on how these elements function in a context where it is hard in practice to achieve deterrence. Third, it assesses how agents view the effectiveness of combinations of style elements in such a context. To do so, it uses survey and interview data with street‐level environmental officials in Guangzhou, China. It finds that the agents studied practise enforcement that goes beyond deterrence and uses education and persuasion more effectively. It finds that the behavioural assumptions of these agents are to a large extent in line with the available regulatory literature, although agents are very unlikely to have consulted such studies. Therefore, the article concludes that law enforcement agents can develop nuanced and appropriate behavioural intuitions through their everyday work experiences.  相似文献

This article examines the relationship between local civil society organizations and community-based structures in peacebuilding interventions in South Kivu in the Democratic Republic of the Congo. It observes that elite led organizations in the provincial capital rely on information provided by the members of multiple community-based structures in order identify local needs which are addressed through their peacebuilding efforts. Further, it argues that the relationship between these two actors present both groups with the legitimacy to undertake peacebuilding activities at the community and provincial level. It argues that local civil society organizations rely on their relationship with community-based structures which they establish and support in order to develop locally grounded peacebuilding interventions and gain the legitimacy necessary to gain access to international funding and implement their programmes in targeted communities in South Kivu province.  相似文献

Adolescents’ conflict management styles with parents are assumed to have an important impact on the quality of the parent-adolescent relationship and on adolescents’ psychosocial development. Longitudinal research investigating possible determinants of these conflict management skills is scarce. The parenting context and adolescents’ tendency to reject maternal authority are expected to shape adolescents’ conflict management styles. Therefore, the present three-wave longitudinal study focuses on how parenting and adolescents’ reactance relates to adolescents’ conflict management styles and conflict frequency with mothers over time, and whether reactance may also explain the associations between parenting and certain conflict variables. We addressed these research questions by using a hybrid cross-lagged panel model with parenting as a latent variable (i.e., supportive parenting) and the other variables as manifest variables. Supportive parenting was measured by four well-known parenting dimensions: autonomy support, responsiveness, psychological control, and harsh control. Four conflict styles were investigated: positive problem solving, withdrawal, conflict engagement, and compliance. Questionnaires were completed by 812 adolescents at three annual waves (52% girls at Time 1). Supportive parenting was associated with fewer conflicts, more positive problem solving, and less compliance and reactance over time. Reactance was associated with more conflicts, conflict engagement and withdrawal, and less compliance. We did not find evidence for the mediating role of reactance in the over-time associations between parenting and adolescents’ conflict management and frequency. Both parenting and reactance appeared important and unique determinants for adolescents’ conflict management styles and frequency.  相似文献

Abstract

We empirically investigate the role of natural resources, and governance in explaining variation in the intensity of conflict during the 1991–2002 civil war in Sierra Leone. As a proxy for governance quality we exploit exogenous variation in political competition at the level of the chieftaincy. As a proxy for resources we use data on the location of pre-war mining sites. Our main result is that neither governance nor resources robustly explains the onset or duration of violence during the civil war in Sierra Leone.  相似文献
