What do Alternative Measures of Peer Behavior Tell Us? Examining the Discriminant Validity of Multiple Methods of Measuring Peer Deviance and the Implications for Etiological Models

Deviant behavior tends to be more strongly correlated with respondents’ perceptions of peer deviance than with actual peer deviance. However, research has yet to discern between two interpretations of this finding. On one hand, respondent perceptions of peer deviance may simply be “biased” indicators of actual peer behavior or alternative measures of one’s own deviance. On the other, respondent perceptions and actual peer deviance may reflect fundamentally separate constructs. The present study uses two separate statistical methods to discern the empirical validity of each interpretation. It then illustrates the importance of the measurement results with a series of cross-lagged panel analyses assessing how a researcher’s operationalization of peer deviance impinges upon conclusions about the bidirectional relationship between personal and peer deviance. Measurement results across two separate behavioral domains (property crime and substance use) suggest that actual peer deviance items reflect a construct fundamentally separate from both personal and perceived peer deviance. Likewise, results fail to support the claim that peer deviance items are simply alternative measures of one’s own deviance. Cross-lagged structural equation results are consistent with the notion that personal deviance affects both later perceptions of peer deviance and actual peer deviance. Yet, null or very weak effects of either peer deviance measure on personal deviance are observed. In light of our findings, we discuss the necessity for new theorizing concerning the complex relations among personal behavior, perceived peer behavior, and actual peer behavior.     

ECOLOGICAL NETWORKS AND URBAN CRIME: THE STRUCTURE OF SHARED ROUTINE ACTIVITY LOCATIONS AND NEIGHBORHOOD‐LEVEL INFORMAL CONTROL CAPACITY

By drawing on the work of Jacobs (1961), we hypothesize that public contact among neighborhood residents while engaged in day‐to‐day routines, captured by the aggregate network structure of shared local exposure, is consequential for crime. Neighborhoods in which residents come into contact more extensively in the course of conventional routines will exhibit higher levels of public familiarity, trust, and collective efficacy with implications for the informal social control of crime. We employ the concept of ecological (“eco‐”) networks—networks linking households within neighborhoods through shared activity locations—to formalize the notion of overlapping routines. By using microsimulations of household travel patterns to construct census tract‐level eco‐networks for Columbus, OH, we examine the hypothesis that eco‐network intensity (the probability that households tied through one location in a neighborhood eco‐network will also be tied through another visited location) is negatively associated with tract‐level crime rates (N = 192). Fitted spatial autoregressive models offer evidence that neighborhoods with higher intensity eco‐networks exhibit lower levels of violent and property crime. In contrast, a higher prevalence of nonresident visitors to a given tract is positively associated with property crime. The results of these analyses hold the potential to enrich insight into the ecological processes that shape variation in neighborhood crime.     

闭路电视监视系统人像识别程序

闭路电视监控系统人身识别证据的质量是一个值得关注的课题。研究表明,熟悉面孔的识别和陌生面孔的识别都具有相当难度,比较而言,熟悉面孔的识别较为可信;反复观看录像资料能否提高对嫌疑人面孔的熟悉程度还需更多的实验;专家证据对于其他法庭证据是一种印证和加强,认为高清晰图像不一定要求专家意见来佐证的看法是错误的。     

Academic Research In a Small Country: Called to Serve!

The literature on the interaction between research communities and policymaking processes comes mostly from scholars in large countries with hundreds if not thousands of people working on international environmental issues. In small countries like Belgium and The Netherlands, however, policy networks of academics and decision makers are quite small. Not only are there opportunities for academic researchers to influence policy decisions - there are high expectations that they do so.     

Post–Conflict Global Governance: The Case of Microfinance Enterprise Networks in Bosnia and Herzegovina

The article examines the institutional infrastructure that supports the foreign aid flows in the mcrocredit sector in postconflict Bosnia and Herzegovina. It documents the mobilization of transnational networks between different international agencies in the course of the policy formulation and implementation, and elicits the effects that certain network attributes exert on the policy choices made by individual organizations. How and why do international governmental and nongovernmental organizations, with at times conflicting goals, join forces in such networks? More important, whose goals are eventually implemented, and under what conditions? Whose goals are diluted in the process of network mobilization? What are the policy implications of such "battles" for the postconflict reconstruction? The article seeks some answers to these questions, demonstrating how transnational networks intermediate between the organizational goals and the final policy outcomes that result from such a network–based mode of global governance in postconflict regions.

Encouraging Political Defection: The Role of Personal Discussion Networks in Partisan Desertions to the Opposition Party and Perot Votes in 1992

Drawing on data from a unique study of the 1992 American presidential election, this article demonstrates that personal discussion networks influence voting behavior, independent of candidate evaluations and partisanship. These social networks encouraged two different kinds of defections from otherwise-expected behavior. People were more likely to vote for Perot if their personal discussants supported him and to convert preferences for him into a Perot vote on election day. Partisans also were more likely to defect to the other major party if their discussion network failed to fully support the candidate of their own party. These results withstood controls for candidate evaluations and partisanship as well as for selective exposure to discussants and selective perception of their preferences. They show the importance of adding social context to personal attitudes, interests, and partisanship in explaining voting behavior.     

The Policy Effects of Internationalization: A Subsystem Adjustment Analysis of Policy Change

This article contributes to a better understanding of contemporary policy analysis and management by setting out the parameters for analyzing policy change induced by internationalization. It first maps the dynamics of policy change in domestic settings and then explores how internationalization has affected the dynamics identified. The central proposition of the article is that internationalization promotes the restructuring of policy subsystems in such as way as to form hospitable circumstances for swifter and deeper policy changes than would otherwise be the case. However, the analysis suggests that this is a two-stage process in that once its initial impact is felt, internationalization serves to entrench and stabilize reconstructed policy systems, thus constraining the scope for further change.     

Network Structure and Perceived Legitimacy in Collaborative Wildlife Management

The widespread supposition that collaborative management designs enhance legitimacy must be examined empirically, and the rich diversity of different collaborative arrangements should be better acknowledged in this endeavor. This study adopts a social network perspective and examines three state‐initiated and interest‐based collaborative management arenas in Swedish wildlife management: wildlife conservation committees (WCCs). Is there a link between social network structures in collaborative management arenas and the perceived legitimacy of output by policy stakeholders? This puzzle is addressed through social network analysis combined with survey data and interviews. The empirical results confirm the notion that collaborative arenas consisting of high network closure with many bridging ties across organizational boundaries enjoy a higher level of support among stakeholders directly involved in management, as members of the committees, than networks with a more sparse structure do. This type of well‐integrated network structure seemingly increases stakeholders’ understanding of other actors’ perspectives through deliberation. Contrary to what was expected, though, the empirical analysis did not verify the effect of linking, or outreaching ties between the committee members and the organizations that they represent, on the organizations’ support of WCC decisions. Given the rapid rise of collaborative designs in public administrations, the topic elaborated in this paper is urgent and further research is encouraged.
