Scholarship has focused on the use of license plate readers by patrol officers as a rational instrument for accomplishing key policing goals, including recovering stolen vehicles. In contrast, this paper applies the theoretical framework of innovation reinvention to explain how license plate readers are being used by criminal investigators in more novel ways. This perspective provides insights into the practical benefits of an enhanced version of this technology. More significantly, it helps illuminate the innovation attributes and the organizational determinants that contribute to its adaptation. In our case study of an agency with extensive deployment of license plate readers, we found that factors contributing to their reinvention included their widespread availability and compatibility with other information systems, their lack of complexity, the characteristics of their users, and the role of leadership in promoting their use. These findings have implications for advancing knowledge about the complex nature of the innovation process. 相似文献

A statistical analysis is made of homicide rates in the 50 largest American cities for four different years. It is shown that differences in recent murder growth among the cities can largely be explained as typical random fluctuations about a common trend. It is also found that the changing age profile of the American people explains no more than ten percent of the increase in homicide since 1964. Several mathematical models for future homicide growth are proposed from the analysis, and under each the probability of death by murder and corresponding drop in life expectancy are estimated for individuals born now in each of the 50 cities. 相似文献

Abstract. Arguments about the incompatibility of globalization and generous welfare spending have given way to more nuanced analyses of how domestic-level institutions mediate the impact of globalization. This article discusses and compares two models – the labour-partisan politics model and the labour-monetary politics model – that identify national-level institutions that are said to make it possible for states to combine generous welfare spending and good economic performance. The empirical analysis shows that the labour-monetary politics model performs better for the period 1973–1989. However, institutional conditions that existed during these years are shown to be rather poor predictors of economic performance in the 1990s. The article goes on to discuss what this suggests for the continued viability of generous welfare spending and argues that while globalization might undermine some institutional settings conducive to continued generosity, there is evidence that other ones remain viable. 相似文献

The nature and quality of adolescents' attachments to peers and parents were assessed with the newly developed Inventory of Adolescent Attachments. The relative influence on measures of self-esteem and life satisfaction of relations with peers and with parents was then investigated in a hierarchical regression model. The sample consisted of 213 adolescents ranging from 12 to 19 years of age. Two hypotheses were tested: (1) The quality of perceived attachments both to parents and peers would be related to well-being, and (2) the quality of parental relationships would be a more powerful predictor of well-being than would the quality of peer relationships. Confirming the study's hypotheses, the perceived quality of the adolescents' relationships to both peers and parents, their frequency of utilization of peers, and their degree of negative life change were significantly related to both measures of well-being. The quality of attachment to parents was significantly more powerful than that to peers in predicting well-being. In addition, quality of attachment to parents showed a moderating effect under conditions of high life stress on the measures of self-esteem. The study suggests that it is useful to consider the quality of attachments to significant others as an important variable throughout the life span. 相似文献

Does the conventional wisdom about the relationships between economic, cultural, and political party variables and democracy stand up in the Latin American experience of the 1990s? This study, utilizing new data sets for the region, finds that some traditional hypotheses are upheld better than others. It sustains the conventional wisdom that economic development, economic growth, democratic values, and (with a two‐year lead) education correlate positively with the level of democracy. Surprisingly, however, neither social trust nor the number of political parties is significantly correlated with the level of democracy. The study suggests various possible explanations for the weak or nonexistent relationships for social trust and number of parties, in the hope that these surprising results will stimulate further research. 相似文献
