Federal first responder funding is estimated to be $98 billion below the minimum required level over the 5 years ending in 2010. A significant portion of that shortfall can be covered by savings attained by eliminating non-public-good services, initiating public–private partnerships for meeting peak time demand in emergency situations, and contracting-out other public services. We concentrate on such savings in the context of response to false calls to police, fire, and ambulance services. Solving the false alarm problem for police, fire, and ambulance services and eliminating some non-public-good police services could release significant service-hours and 23.7–31.4% of the required additional Homeland Security (HLS) annual spending. Reducing false alarms means 88,000 police, fire, and ambulance first responders could be shifted to HLS activities.

The paper reports on the core challenges faced by the nonprofit, political and social marketing disciplinary areas and suggests a series of research agendas to develop theory and practice to meet these challenges.
  • Social marketing's research agenda involves the continued adaptation of the new developments in commercial marketing, whilst building a base of social marketing theory and best practice benchmarks that can be used to identify, clarify and classify the boundaries of social marketing against social change techniques.
  • Nonprofit marketing is pursuing the dual research agenda of developing the theory and practice of social entrepreneurship whilst seeking deeper consumer‐based research to understand motivations for charitable behaviour and gift giving.
  • Political Marketing's research agenda looks for an increase in the level of background research, core data and market research to use as a basis for developing more advanced theoretical and practical models. In addition, as political marketing is being transferred internationally between a range of political and electoral systems, there is a need for comparative research into both the relevance and effectiveness of these techniques to isolate nation independent and nation dependent political marketing strategies and campaigns.

In a world that is increasingly dominated by literary hyperbole there can be no doubt that Bernard Crick's In Defence of Politics remains a classic text. Classic not just in the sense that it provides a masterly account of the essence, meaning and fragility of democratic politics but classic in the sense that it is written with a style, verve and passion that is rarely found within political science. If the test of pretensions to ‘a classic’ status is that a book defies the passage of time in terms of significance and argument then Crick's Defence would also make the grade for the simple fact that its arguments remain arguably far more important today than they were when they were first published exactly fifty years ago. This article reflects on the contemporary significance of Crick's Defence by defending politics against an updated set of adversaries in the form of: public expectations, marketisation, depoliticisation, the media, and crises before locating the book within the contours of current debates about public disengagement, the rise of ‘disaffected democrats’ and questions concerning the future and relevance of political science.  相似文献

This article examines the impacts of Building Strong Families, a healthy marriage and relationship skills education program serving unmarried parents who were expecting or had recently had a baby. Based on a random assignment research design, the analysis uses survey data from more than 4,700 couples across eight research sites to estimate program effects. Results varied across sites, with one site having a pattern of positive effects (but no effect on marriage) and another having numerous negative effects. However, when impacts are averaged across all research sites, the findings indicate that the program had no overall effects on couples’ relationship quality or the likelihood that they remained together or got married.  相似文献

Participation in legislative debates is among the most visible activities of members of parliament (MPs), yet debates remain an understudied form of legislative behavior. This study introduces a comparative theory of legislative speech with two major implications. First, party rules for debates are endogenous to strategic considerations and will favor either party leadership control or backbencher MP exposure. Second, in some systems, backbenchers will receive less time on the floor as their ideological distance to the party leadership increases. This leads to speeches that do not reflect true party cohesion. Where party reputation matters less for reelection, leaders allow dissidents to express their views on the floor. We demonstrate the implications of our model for different political systems and present evidence using speech data from Germany and the United Kingdom.  相似文献

Spectral analysis and ARMA models have been the most common weapons of choice for the detection of cycles in political time series. Controversies about cycles, however, tend to revolve around an issue that both techniques are badly equipped to address: the possibility of irregular cycles without fixed periodicity throughout the entire time series. This has led to two main consequences. On the one hand, proponents of cyclical theories have often dismissed established statistical techniques. On the other hand, proponents of established techniques have dismissed the possibility of cycles without fixed periodicity. Wavelets allow the detection of transient and coexisting cycles and structural breaks in periodicity. In this article, we present the tools of wavelet analysis and apply them to the study of two lingering puzzles in the political science literature: the existence of cycles in election returns in the United States and in the severity of major power wars.  相似文献

In a context where clientelism is widespread, why do some politicians choose not to condition the delivery of goods and services to citizens on individual political behavior? I argue that the answer to this question lies in the heretofore unexamined electoral costs of clientelism: clientelism decreases support from nonpoor constituents even while it generates votes from among the poor. Taking into account these costs and other factors that shape politician incentives, I posit that the interaction between political competition and poverty will explain variation in clientelism. I test this claim using an original measure of clientelism that assesses mayoral involvement in social policy implementation in Argentine municipalities. The results of statistical analysis suggest that high levels of political competition are compatible with clientelism when poverty is also high. Only when high competition is coupled with low rates of poverty does clientelism decline.  相似文献

Inductively coupled plasma mass spectrometry measurement of the relative concentration of sodium, chloride, calcium, and potassium ions in eccrine sweat deposits from 40 donors revealed positive correlations between chloride and sodium (ρ = 0.684, p < 0.01) and chloride and calcium ions (ρ = 0.91, p < 0.01). Correlations between ion concentration and the corrosion of α phase brass by the donated sweat were investigated by visual grading of the degree of corrosion, by measuring the copper/zinc ratio using energy-dispersive X-ray spectroscopy, and from a measurement of the potential difference between corroded and uncorroded brass when a large potential was applied to the uncorroded brass. An increasing copper/zinc ratio (indicative of dezincification) was found to correlate positively to both chloride ion concentration and visual grading of corrosion, while visual grading gave correlations with potential difference measurements that were indicative of the preferential surface oxidation of zinc rather than copper.  相似文献
