Observer determination of the make,model, and year of questioned vehicles

Often, criminal acts involving a vehicle are caught on digital video surveillance systems. While potentially useful for an investigation, the recording conditions are typically less than optimal for the extraction of key information for the identification of the perpetrator, such as a license plate. Providing the make, model and year of a questioned vehicle is a common request for examiners, to narrow the field of potential suspect vehicles. This study seeks to compare the performance of a nonpeer-reviewed make, model, and year determination between two separate groups, specifically, trained forensic image examiners and nontrained individuals. Results show that even with varied image capture conditions and quality, the trained forensic image examiners more correctly and completely identified the test group of questioned vehicles make, model, and year.     

Inner-city birth rates following enactment of the Minnesota parental notification law

An increase in birth rates to Minneapolis minors following the enactment of a parental notification law was examined. A well-publicized link between increasing birth rates and the law is shown to have been premature. Birth, abortion, and population data by age, race, and region suggest that the increasing birth rate in Minneapolis was not related to parental notification, but rather to a growing racial minority population.Preparation of this article was supported in part by an Aldeen Grant from Wheaton College. The authors wish to thank the Minnesota Center for Health Statistics, particularly James Wigginton and Carol Vargas, for their considerable work to provide birth, abortion, and population data in a form suitable for the current analysis. The authors also thank Americans United for Life for purchasing the data and providing them to the authors.     

Ideas, Interests, and Institutions: Challenging the Property Rights Paradigm in Botswana

Recent work in international studies and comparative politics scrutinizes the relative importance of ideas, interests, and institutions as sources of policy change. A growing body of scholarship identifies ideas as the main causal factors, influencing perceived interests as well as perceived policy options. Others contend that policies can best be understood as products of institutions. Neither explanation can account for both policy choice by politicians and the implementation strategies of administrators. In Botswana, the use of professional criteria for hiring and advancement encourages adherence to international professional norms within the bureaucracy, but electoral competition gives politicians more reason to be attentive to local political concerns. The institutions that define relations of authority among actors with different motivations shape the outcomes of policy choice and implementation. Institutions influence the attentiveness of policy-makers to ideas when making decisions, the degree of attention particular policy-makers give to ideas from particular sources, and the degree of acceptance that ideas must achieve to affect policy. Better evaluations of political development can be achieved through attentiveness to the mix of actors involved in policy decisions, the diversity of institutions and ideas that affect their policy preferences, and the relations of authority that shape their relative influence over policy choice and implementation.
