Over 10% of the American electorate lives in counties served by out-of-state media because of the mismatch between media markets and state boundaries. Frequently, these “orphan” counties face a different information environment than others in their home state: they receive no news coverage and political advertising for their own statewide races, irrelevant information pertaining to candidates in the neighboring state who will not appear on their ballots, or both. With a combination of county-level, individual-level, and political advertising data, our analysis evaluates the effect of orphan county residency and irrelevant political information on political participation. Results indicate that orphan counties have lower turnout rates than non-orphan counties and that this difference is explained by lower levels of interest in the campaign stemming from exposure to irrelevant information. 相似文献

Raman spectroscopy has found increased use in the forensic controlled substances laboratory in recent years due to its rapid and nondestructive analysis capabilities. Here, Raman spectroscopy as a screening test for methamphetamine in clandestine laboratory liquid samples is discussed as a way to improve the efficiency of a laboratory by identifying the most probative samples for further workup among multiple samples submitted for analysis. Solutions of methamphetamine in ethanol, diethyl ether, and Coleman fuel were prepared in concentrations ranging from 0.5% to 10% w/v, and Raman spectra of each were collected. A concentration‐dependant Raman peak was observed at 1003 per cm in each solution in 4% w/v and greater solutions. Case samples were analyzed and also found to reliably contain this diagnostic peak when methamphetamine was present. The use of this diagnostic indicator can save the forensic controlled substances laboratory time and materials when analyzing clandestine laboratory liquid submissions. 相似文献

Although empirical research has generally demonstrated that democracies experience more terrorism than autocracies, research suggests that this depends upon complex institutional differences that go beyond the democracy‐autocracy divide. This study examines these differences, linking institutions to strategies of coercion and co‐optation. Using zero‐inflated negative binomial regression estimations on Geddes’ (2003) autocratic regime‐type data for 161 countries between 1970 and 2006, we find that single‐party authoritarian regimes consistently experience less domestic and international terrorism relative to military autocracies and democracies. This finding is robust to a large number of specifications, underscoring the explanatory power of regime type for predicting terrorism. Our explanation for these findings is that party‐based autocracies have a wider range of coercion and co‐option strategies that they can employ to address grievance and dissent than do other, more strategically restricted, regimes. 相似文献

A study of a neglected period in British foreign policy serves to question schematic approaches to the history of international relations and to underline the indeterminacy felt by contemporaries, and their sense of the roles of contingency and personality. The problems faced then in conceptualizing international relations can be mirrored today. 相似文献

The “new managerialism” is becoming the new ortodoxy in public administration. It has challenged the classic assumptions about the nature of bureaucracy in democratic countries. However, it has not implied a great deal of serious debate. In Canada, it is challenging the model of constitutional bureaucracy around which public administration has been organized. Such a model involves two main principles: the ministerial Department and a neutral career public service. The former has meant that power flow in downward and responsibility and accountability upward (to the elected state authorities). The latter that, among other things, officials enjoy security of tenure in exchange for their willingness to serve governments of all partisan affiliations with equal loyalty and effectiveness. The new managerialism challenges both principles since it proposes to diffuse authority both horizontally and vertically, make accountabi1;ty run downward to “clients” and be more capable to substitute personell according to the needs of the moment. Since the new managerialism involves serious risks, the author ends up asking whether these two contending paradigms can or should be reconcilied, and warning not to overlook the past histories of Canadian and Western administrative and political institutions. 相似文献

Using a sample of full-time employees of a public sector organisation in South Korea, this study examines whether transformational leadership (TL) has a significant positive effect on affective commitment (AC) and organisational citizenship behavior (OCB), and whether AC is positively related to OCB. The study also examines whether AC mediates the effects of TL on OCB. The results of higher-order structural equation modeling indicate a positive relationship between TL and AC; no significant relationship between TL and OCB; and a significant positive relationship between AC and OCB. Thus, the results clearly demonstrate that AC fully mediates the relationship between TL and OCB. Theoretical and practical implications of these findings are discussed, and proposals for future research are made. 相似文献
