This article studies invalid voting, which has received very little attention so far, given the broad interest and substantial relevance of voting behaviour research. Existing evidence is mostly limited to rather specific and hardly representative countries. Yet, the extent of invalid ballots is not negligible. Despite undemanding electoral rules, more invalid votes are cast in German general elections than votes for niche parties. Against this backdrop, the article describes prevalence of invalid voting in the mixed electoral system of Germany and tests explanations of its variation between constituencies. Analysing data from the most recent Bundestag Election, results give clear support to politico-institutional explanations: voters are more willing to waste their vote if second-order elections are held concurrently. Specifically under the plurality rule, more (first) votes are wasted if there are large shares for parties without direct candidates and many competing candidates. 相似文献

This report describes the histological changes observed in the heart a young methamphetamine abuser who died of heart failure. Most of the microscopic changes in the heart have previously been described in experimental animals, but never clearly illustrated in man. Gross examination of the heart revealed concentric myocardial hypertrophy (heart weight 470 g versus median predicted weight of 312 g). Areas of old myocardial infarction were also evident, along with enzymatic evidence indicating that a new infarct had occurred. Myocardial remodeling was extensive with perivascular and interstitial fibrosis, cellular vacuolization, and ongoing myocyte destruction with proliferation of fibromyocytes in the intestitum. Of note were the widespread, bizarre looking, distorted, cell nuclei. They were reminiscent of those seen in viral-induced dilated congestive cardiomyopathy. Clinical chemical measurements also showed unequivocal evidence of both evolving infarction and profound heart failure, with a BNP > 5000. This pattern has not previously been reported in humans, probably because forensic pathologists rarely examine the hearts of methamphetamine abusers microscopically. If the pattern observed here is typical for methamphetamine-induced cardiotoxicity, it could well explain increasing reports of heart failure in methamphetamine abusers. It might also be diagnostic for the disorder. 相似文献

Electronic control devices (ECDs) deliver high‐voltage, low‐current energy pulses temporarily paralyzing a person. For the ECD–human interaction, we have developed a computer model using the SEMCAD program within which to simulate the electrical effects throughout the body resulting from the imposition of an ECD pulse at a particular point on the body surface. Our human body models were based on cross‐sectional MRIs and CT scans, with the dielectric properties of the various tissues assigned based on previously published values. We simulated the application of a single ECD pulse and calculated the resulting electric field strength and current and charge densities at different body locations. The results were compared with corresponding values obtained by other researchers in similar simulations. Furthermore, we simulated an application of a pulse of 20‐millisecond duration equal to the European household current of 50 Hz and to the ventricular fibrillation threshold. The resulting current level indicated at the heart muscle was 1/5 the level considered the threshold for triggering ventricular fibrillation. 相似文献

针对公务员惩戒制度,中国《公务员法》进行了一定范围的法律规范。但与德国《联邦惩戒法》、《联邦公务员法》中的相应制度安排相比,中国目前的规定较为抽象并缺乏可操作性。尤其是针对公务员在惩戒程序中的部分基本权利,例如查看档案权、参与调查权、委托律师权等,《公务员法》均未作出规定。从整体上看,中国制度下的公务员在程序中的角色过于被动,几乎无机会主动参与调查环节。为了确保被惩戒公务员合法权利的保障并提高整体程序的客观性,可考虑将德国法律中部分具体权利保障制度纳入到《公务员法》今后的修订范围当中。 相似文献

Why do groups adopt terrorism? Major theories of terrorist radicalization assume it to be a rational process whereby groups select terrorism as the policy most likely to advance their goals. Not all terrorism is rational, however, and these theories cannot explain cases when groups pursue terrorism despite it being self-defeating. We distinguish between rational and irrational terrorism, and explain the latter using social psychology's groupthink mechanism. Although terrorists are widely assumed to be vulnerable to groupthink, empirical work on the phenomenon has focused overwhelmingly on decision-making by national executives. We firmly establish the link between groupthink and terrorist radicalization by tracing groupthink's operation through the development of the Weather Underground, an American terrorist group that emerged in the late 1960s and conducted six years of bombings against the U.S. government. All of the antecedent conditions, symptoms, and decision-making defects predicted by groupthink are evident in the Weather Underground, providing valuable evidence of the dangers of irrational radicalization and offering lessons for its prevention. 相似文献

Various 9‐mm ammunitions (A1, A4, A5, ST, GS, GSb, P.E.P., SeCa, HP, PTP/s, VM, McVG, DM41, PTP, SX2, PT, and MEN frangible) were tested regarding their velocity, energy, angle of impact, and potential wound channel after penetrating a car window at 30° and 90°. Test materials were gelatine, soap, and pig cadavers. The velocities of the projectiles were between c. 288 and 430 m/ses, the energy spread between 394 and 564 J. Handgun bullets fired through vehicular side window glass lose substantial energy reducing the effectiveness of the ammunition. This effect is greater when fired at an angle of 30° compared to 90°. At a shooting angle of 90°, none of the different projectiles showed remarkable differences considering its wound ballistic features. Accuracy is maintained at a 90° angle but seriously impaired at 30°. None of the examined ammunition complied with the demanded wound channel effectiveness of 30–60 J/cm. 相似文献

We test for the influenceof government strength and dispersion ofpower among the parties of coalitiongovernments on the size of annual debtaccumulation through budget deficits inOECD-countries from 1970 to 1999.Government strength and power dispersion incoalition governments are measured by theBanzhaf index of voting power, respectivelythe standard deviation of Banzhaf indicesof coalition parties. We believe that theseare better-suited proxies than most of whathas been applied so far. Governmentstrength turns out to be insignificant.However, coalitions with equally strongpartners run significantly higher deficitsthan coalitions with one dominating party. 相似文献

ABSTRACTThis study deals with the contemporary dynamics of urban life in Bishkek. Since the dissolution of the Soviet Union, Central Asian societies have experienced widespread political, economic and socio-cultural transformations. In this context, Western or globalized cultural modes and trends influence Kyrgyzstan's social and cultural life. One of these trends is the increasingly popular coffee culture, with its attendant high-grade coffee brands and fancy cafés changing established consumption patterns. This article focuses primarily on cafés as new places of consumption and communication, but it also examines the intentions and strategies of the café pioneers. We reflect on the emergence of coffee and cafés in Bishkek and show how they have integrated in urban life as ‘third places’. Coffee is breaking away from its commonly soluble form and moving toward an expensive lifestyle product, while the new cafés offer a place for communication that has not existed before. 相似文献

Lijphart's spectrum of democracies – recently expanded by Jack Nagel to a sub-majoritarian sphere of pluralitarian systems which use disproportional electoral systems in order to manufacture majority governments from minorities in the electorate – is based on only one dimension: inclusion of preferences. Political scientists in the Lijphartian tradition wrongly assume that inclusion of preferences, which is an input characteristic, automatically leads to responsiveness, which refers to actual policy decisions and hence is an output characteristic. We therefore add 'responsibility' as a second input characteristic and employ it alongside the inclusiveness of institutional regimes. We argue that in representative democracies there exists a trade-off between inclusiveness and responsibility. This trade-off helps us to measure the democratic quality of institutional regimes. The now expanded spectrum of democracies based on these two dimensions shows that majoritarian democracy proper – in which governments represent a majority of individual preferences but not more than necessary – is the best possible combination of the two democratic values. 相似文献
