Law enforcement agencies are adopting a variety of new surveillance technologies at a fast pace. These technologies could have substantial benefits in terms of public safety, but, for many of them, their ability to reduce crime is unknown. Although a small experimental literature addresses some of these technologies, many of the implementations have been too small to provide an accurate measurement of their potential. In this paper, I explore the advantages and make general suggestions about the use of quasi-experimental methodologies in estimating the public safety benefits of police technology. I also consider the specific case of license plate readers and provide some examples of difference-in-differences approaches that could be used to study their efficacy.
This paper discusses the internal dynamics of American trade policy making in the context of the Transatlantic Trade and Investment Partnership (TTIP) negotiations. The author describes the active role interest groups, the U.S. business community, and representatives on both sides of the political spectrum have played in the passing of Transatlantic Partnership Agreement (TPA), the TPP negotiations, and currently the TTIP debate. Lastly, the author lays out the challenges TTIP will continue to face in light of opposition to specific TPP provisions, trans-atlantic disagreement over ISDS and data flows, and the recent presidential elections.
The aim of this study is to examine the influence of humble and empowering leader behaviors on the prosocial voice of subordinates. We also investigate subordinate power distance orientation as a possible moderator of this relationship and subordinate psychological empowerment as the underlying mechanism behind this moderated effect. Findings from 306 employees of a Korean business conglomerate indicated that humble and empowering leadership were positively related to the prosocial voice of subordinates, and the moderation effects of subordinates’ power distance orientation between these two types of leader behaviors and subordinates’ prosocial voice were fully mediated by the extent to which they felt psychologically empowered. Our findings indicated that the moderation for the main effect between leadership and voice was caused by the significant moderating effect in the indirect path between two main variables via psychological empowerment. We conclude by highlighting implications for management practice and identifying avenues for future research.
