Networks and managing in the network have been central concerns of public management scholars for years ( Provan and Milward 1991 ; O’Toole 1997 ; Agranoff and McGuire 2003 ; Herranz 2008 ). The literature has investigated the extent of networks ( Hall and O’Toole 2004 ), the appropriate way to measure networks and networking behaviour ( McGuire 2002 ; Meier and O’Toole 2005 ), and the role that networking plays in improving organizational performance ( O’Toole and Meier 2003 ). Although there are qualifications in the literature to the rosy scenario that managing in the network is always a good thing ( O’Toole and Meier 2004 ), and although the benefits of managerial networking show diminishing returns ( Hicklin et al. 2008 ), there has not been much investigation of the factors that enhance or detract from networking's impact on performance. This study examines the interactive relationship between management capacity and managerial networking using a panel of several hundred public organizations over an 8‐year period. The empirical results show that managerial capacity does interact with networking and enhances the positive impact of networking over an array of performance indicators. At the same time, building managerial capacity is a central management choice, and that decision has ramifications for organizations that are not always positive. The paper concludes with the managerial implications of the strategic choice to build management capacity. 相似文献

Britain is a good place to test hypotheses about the impact of the mass media on political attitudes and behavior, and this article uses the British Household Panel Survey to investigate the impact of the national daily press on turnout in the general elections of 1992 and 1997. The evidence does not support the hypothesis that reading a newspaper regularly helps to mobilize people on election day, but it also does not support the claim that the daily press--even the notorious British tabloid press--helps to induces political apathy. On the other hand, the evidence is consistent with the hypothesis that those whose political attitudes and party identification are reinforced by the paper they read regularly are significantly more likely to vote than those whose attitudes and ID are cross pressured by the paper they read. As predicted, this newspaper effect is statistically significant but not large. The newspaper effect is larger in the close-fought election of 1992 than in the landslide Labour victory in 1997. And it is larger for the "Labour reinforced" than the "Conservative reinforced." The article concludes that the British national press has a statistically significant effect on political behavior in the form of turnout in British elections, especially when election results are close. This, in turn, suggests that the extent to which the Conservative press dominated daily circulation in Britain during 1945-1992, may have helped the Conservative party win elections. 相似文献

We describe a model of electoral selection and legislative policy choice that explores the effects of term limits on legislative spending. In the model, self‐interested voters in a collection of districts prefer representatives who deliver pork over representatives who maximize aggregate social welfare. Term limits can, in some cases, inhibit voters from selecting representatives who deliver particularistic benefits, and, in these cases, term limits reduce pork spending. On the other hand, when pork is extremely socially inefficient, representatives who want to deliver pork to their districts have incentives to refrain from doing so to reduce future pork in other districts. In this scenario, term limits actually prevent legislators from promoting future spending moderation and thus paradoxically increase pork spending. 相似文献

This research reassesses the role of policing and drugs in the sharp homicide decline in New York City in the 1990s. Drawing on theoretical arguments about “broken windows” policing and lethal violence associated with the diffusion of crack cocaine, we estimate the effects of measures of misdemeanor arrests and cocaine prevalence on homicide rates with pooled, cross‐sectional time‐series data for 74 New York City precincts over the 1990–1999 period. The results of mixed regression models reveal a significant negative effect of changes in misdemeanor arrests and a significant positive effect of changes in cocaine prevalence on changes in total homicide rates. Additional analyses of homicide disaggregated by weapon indicate that the effects of misdemeanor arrests and cocaine prevalence emerge for gun‐related but not for non‐gun‐related homicides. Overall, the research generally supports influential interpretations of the homicide decline in New York City but also raises questions about underlying mechanisms that warrant more inquiry in future research. 相似文献

This research examines the extent to which public pension programs allocate assets in a manner that is consistent with an optimal portfolio, as defined by Modern Portfolio Theory (MPT). The examination is pursued by way of a statistical analysis, using a portfolio optimization model and data on some of the nation's largest public DB plans. The analysis illustrates that the majority of the plans in the sample are incurring far more risk in their portfolios than is optimal given their target rates of return and that this risk level is a result of nonprudent allocation across asset classes. The findings suggest that there might be opportunities to improve the long‐term performance of defined benefit plans by adjusting asset allocation targets and legal lists in a manner that is more consistent with MPT. 相似文献

Three variables were hypothesized to cause a fear of crime and a potential change in behavior. These were: (1) crimes against a person rather than crimes against property; (2) a crime committed in an area frequented rather than a crime occurring in an area one never entered; (3) a recurring crime rather than a crime that occurred once. Two different samples of female subjects (n = 249) were approached at their residences and were asked to read one of a number of fictitious crime stories that the news media supposedly had not reported and to complete two scales measuring: (1) an emotional response to crime and (2) a potential behavioral response to crime. The results indicate that a physical assault produces both more fear and more potential behavioral change than a burglary. A crime that occurs eight times causes people to consider taking precautions in comparison to a crime that occurs once. There is some evidence that a crime in an area one frequents causes more fear than a crime occurring in an area one never enters. 相似文献

Depression is a widely noted reaction among persons confronted with dramatic life changes. Those released from total institutions (mental patients, prisoners of war, hostages, ex-convicts) are especially susceptible to these symptoms. A model, based on extensive field experience and a broad review of literature, is first presented. Data from a cohort of persons released from prison, gathered at three points in time during the first year following release, are then discussed. The results suggest: (1) support for Irwin's model of "reentry," (2) that depression may accompany positive as well as negative life events, and (3) the importance of "bridging networks" in modifying the intensity of depressive symptoms. 相似文献
