The behavioral work context in which members of groups interact with each other is crucial for facilitating knowledge exchange and combination (Nonaka in Great minds in management: the process of theory development, Oxford University Press, Oxford 2005; Nonaka et al. in Long Range Plan 33:5–34, 2000). Yet little is known about the ways leaders, by signaling expectations and exhibiting supportive behaviors, facilitate such a behavioral context, which may then enhance performance. This study aims to contribute to the literature by examining how leader expectations and supportive behaviors facilitate behavioral integration and enhance the performance of work groups engaging in the development of advanced technological products. Data collected from management teams of 102 work groups indicate significant and positive relationships between: (1) leader expectations and leader supportive behaviors, (2) leader supportive behaviors and group behavioral integration, and (3) behavioral integration and group performance. In addition, the results indicate that leader supportive behaviors partially mediate the relationship between leader expectations and group behavioral integration, and the latter partially mediates the link between leader supportive behaviors and group performance. No significant link was found between leader expectations and group performance. In so doing, this study contributes to research on the way leaders, by shaping a behavioral context, facilitate knowledge exchange and combination, thereby enhancing group performance. 相似文献

Transgovernmental cooperation among domestic regulators has generated considerable interest among scholars and policymakers. While previous research has focused on describing such regulatory networks, we know very little about what drives individual jurisdictions to join them. The question of membership is important because it determines the reach of rules and standards promulgated by a given network, and because it is logically prior to understanding the rulemaking dynamic within a network. We develop a set of hypotheses that highlight the role of domestic political factors in shaping network membership. Our empirical analysis, using an original data set for transgovernmental cooperation in securities and insurance regulation, finds that the institutional form of domestic market regulation, as well as the relative domestic weight of the industry, are closely correlated with membership. All else equal, jurisdictions with independent regulatory agencies and those where the industry in question represents a large share of gross domestic product are much more likely to join the respective network than jurisdictions without these characteristics. The paper underscores the important interactions between domestic and international factors for informal cooperation, an issue that has become increasingly central to global governance. 相似文献

Prolapse rectum (PR) or protrusion of the rectum beyond the anus occurs frequently in populations at both extremes of age. In the pediatric population, in developed countries, the commonest cause for PR is thought to be cystic fibrosis (CF). Treatment options for CF include conservative management, surgical resection and fixation, suturing, and injection sclerotherapy (IS). The last is considered an attractive treatment option because it is minimally invasive. In this case report, the authors present the details about a 2-year-old female child, with PR and CF, who died after IS, using phenol as the sclerotherapeutic agent. Autopsy findings and toxicology tests performed to establish phenol toxicity are documented. The available literature is reviewed. This case report underscores the risks of using phenol for IS and emphasizes the point that the procedure is not innocuous and an adverse outcome including fatality is a possibility. 相似文献

The International City and County Management Association, (ICMA), ensures that members who engage in misconduct are identified and sanctioned. Dozens of public sanctions have been issued over the past 20 years, and this paper considers the substance of these penalties. The article identifies the processes used to ensure compliance with its code of ethics. We report the types of ethical violations ICMA has discovered through these processes. A more systematic way of recording what is occurring is necessary if strategies are to be devised to help current and upcoming public administrators avoid similar violations. Finally, we ask public administrators who have been sanctioned by ICMA to explain how and why the ethics violations occurred and the impact of the public censure on their personal lives and careers. 相似文献

In enacting a legislative Code of Childhood and Adolescence in 1998, the Nicaraguan state formally endorsed the ideal of children's rights as being a central concern of public policy. Yet, the state has done little to fulfil this commitment. In part this is the result of severe fiscal constraints, which have led to reduced public expenditures and the downsizing of social services, especially those directed towards children and youth. In part, however, there are also indications of state reluctance to actively implement the principles of change as outlined by the Code. This has been reflected in the government's reactionary response to fears of growing youth violence, and its unwillingness to collaborate with local civic groups in dealing with youth crime. We surmise therefore that, while the Code may have served to enhance state legitimacy, the cause of children's rights remains a residual policy issue in Nicaragua. 相似文献

Climate change has caused significant hardship in sub-Saharan Africa. As a result, Kenya and Nigeria now have statutes that focus on climate change mitigation and adaptation. Both countries are also parties to the Paris Agreement. The Kenyan Climate Change Act (2016) and the Nigerian Climate Change Act (2021) are similar in terms of their design and overarching aims. Meanwhile, certain pivotal statutory provisions in both statutes are inconsistent with their overarching aims of enhancing appropriate responses to climate change. There is considerable scope for access to justice to be enhanced in the Kenyan and Nigerian statutes. Further, despite their similarities, the divergent approaches of the statutes undermine regional coherence. Such coherence is critical to effectively addressing climate change because both regional powers face similar vulnerabilities with respect to climate change and socio-economic challenges. This article, therefore, undertakes a comparative analysis of the Kenyan and Nigerian legal regimes in two key respects, namely, (1) institutional structures and how they impact corruption and (2) accessing justice in the context of climate litigation. The Nigerian regime is behind that of Kenya in both regards. The article concludes by examining how the Aarhus Convention and the International Access to Justice Convention can help to fill any statutory gaps concerning access to justice. 相似文献
