We argue that plurality systems strengthen the accountability of governments towards the electorate while proportional systems lead to a broad representation of voter interests in parliament and coalition governments. We demonstrate these effects in an analysis of all German federal elections from 1949 to 2017 using first-tier votes and directly elected deputies as reflecting the plurality segment and second-tier votes and the seat shares of parties as reflecting the proportional representation segment. We show that the percentages of directly elected deputies react more to differences in perceived party competences (party valences) than the percentages of all party deputies. Electoral system reforms should take into account the effects of both parts of the German electoral system. 相似文献

Extracurricular activities provide a key context for youth development, and participation has been linked with positive developmental
outcomes. Using data from the 4-H Study of Positive Youth Development (PYD), this study explored how the intentional self
regulation ability of youth interacted with participation in extracurricular activities to affect PYD among adolescents living
in neighborhoods with relatively low ecological assets. In total, 545 youth were included in the study (50.3% female). Most
of the youth were European American (41%) or Latino (37%; African American, 10%; Asian American, 7%; Native American, 4%;
and other, 1%). In general, youth with the greatest capacity to self regulate benefitted the most, as compared to their peers
with less capacity to self regulate, from involvement in extracurricular activities. Consistent with a developmental systems
perspective, and specifically with bioecological theory, the findings from this study confirmed that, within lower asset settings,
children with the most positive person-level factors (intentional self regulation) benefit the most from proximal processes
such as extracurricular activity involvement. 相似文献

Official Development Assistance has been the most important instrument of Japan's foreign policy towards China since 1979 and has been useful in softening many difficulties in the bilateral relationship. Most of Japan's ODA to China consists of yen loans. Usually the Japanese government adheres to certain economic indicators set by the international banking institutions in order to phase out ODA programmes. However, in 2005 the Japanese government decided abruptly without applying the usual guidelines to end its loan aid to China by 2008, the year China will stage the Olympic Games. The article concludes that the decision was taken for political reasons, taking into consideration the criticism of certain Chinese policies, the deterioration of Japan's relations with China, the fast economic development of China with its implications for Japan's interests, and a general aid fatigue of public opinion against the backdrop of Japan's economic and budgetary problems. The process leading to this decision throws an additional light on all the complexities of the bilateral relationship, including the historical legacy. 相似文献

The provision of subsidized child care has grown to become asizeable economic activity in Sweden during recent decades.This paper examines the changed financial relation betweencentral and local governments and the impact of child-caregrants on local government behaviour. We find that during anearlier regime, with a system of matching grants, localgovernments responded strongly to the incentives of the rules.This resulted in both intended and unintended outcomes, aswell as a distortion of information to the central government.Experiences from a recent transition of regime towards a kindof closed block grant system, illustrates new types ofadaptive behaviour but also the problem of finding a formulafor a fair allocation of resources among local governments.When designing a block grant system a distinction must be madebetween expenditures and resource needs; cost expenditure datado not necessarily reflect resource needs in cases where thereare national categorical equity goals related to socialservices of a merit-want character. 相似文献

The human teeth are a valuable source of information concerning identification and age calculation in forensic sciences. Dental treatment often causes permanent alteration of the teeth, which is visible on radiographs. The correlation of prosthetic restorations, root canal fillings and periodontal bone loss with chronological age has not yet been used for determining the completed 18th year of life in teenagers and young adults, e. g. for legal and anthropological purposes. The aim of this study was to determine whether the evaluation of such findings on radiographs correlates with the chronological age in teenagers and young adults. MATERIAL AND METHODS: The dental X-rays (orthopantomogram, OPG) of 1053 outpatients (age: 14 to 24 years) were avaluated. The values "prosthetically restored", "filled dental root", or "periodontal bone loss" were recorded for each tooth present. The data were then evaluated using statistical tools. RESULTS: The correlation between the number of prosthetically restored teeth and the chronological age is high. The positive predictive value of determining an age of at least 18 years proved to be very high. However, these findings are rarely present in this age group. The number of endodontically treated teeth correlated less exactly with age. On the other hand, the determination of periodontal bone loss gave reasonable positive predictive values for the threshold value "chronological age of 18 years or more". DISCUSSION: This study provides for the first time predictive values for the estimation whether a person is 18 years of age, based on the evaluation of teeth with prosthetic restorations, root canal fillings or periodontal bone loss on OPGs only. Whereas the number of patients with such findings is generally low in this age group, some of the positive findings can be used for age estimation as an adjunct to other sources of age calculation. The sole application of these criteria is not recommended, as sanitary conditions of the teeth depend on both social and individual circumstances. Therefore, the calculated values also reflect the culture of the sample studied. Finally, they are time-dependent and have to be compared to data from other populations. These results have some bearing on the field of forensic odontology. 相似文献

The second part of the paper on suicides by gunshots to the head in the presence of witnesses focuses on relevant morphological autopsy findings such as entrance site, signs of close range or contact shots, bullet path etc. and also discusses selected aspects of ascertaining gunshot residues. For the identification of the shooter an integral medicolegal assessment of all the facts including the investigation results and the autopsy findings is essential. However, the morphological findings alone do not allow safe diagnosis, as for example in a homicide the temporal region, which was affected in all our cases, may have been deliberately chosen by the perpetrator as a localization typical of suicide. Thus methods to ascertain gunshot residues on the firing hand (by means of adhesive films and the polyvinyl-alcohol collection method--PVAL) are of great practical importance. In seven cases adhesive films and/or the polyvinyl-alcohol collection method were used. In one case the gunshot residues (GSR) were analysed by means of tape lifts and subsequent scanning electron microscopy (SEM). It was found that especially the combined application of topographical (adhesive tape/PVAL) and cumulative (SEM) methods allowed for the doubtless identification of the shooter, thus usually confirming the suicide. By the example of one case it is demonstrated that without the immediate collection of evidence at the scene objective reconstruction of the event becomes impossible. On the basis of the reported cases recommendations are finally given for a differentiated approach in the medicolegal evaluation of alleged witnessed suicide by gunshot (to the head). 相似文献
