This article explores both the party potential of the five major parties in Switzerland at the 2003 elections and how well the parties actually did in relation to how well they could have done. A party's electoral potential depends on both the probability of the electorate voting for the party and on the probability of individual voters participating in an election. The analysis shows that the SVP and the CVP were successful in mobilising their potential voters in the 2003 elections, while the FDP did almost as badly as they could have done. However, compared to the potential of the FDP or the SP, the overall potential of the SVP is limited. For the SVP, issue specific factors account for the mobilising success. This is especially the case for its stands against the EU and asylum seekers. The CVP profited from the Ruth Metzler effect, who was a key figure in the 2003 CVP campaign.  相似文献

The horrifying, tragic events of 9/11 made Americans aware of their vulnerability to terrorist attacks and triggered the creation of the Department of Homeland Security along with a substantial increase in federal spending to both thwart terrorist attacks and to increase our ability to respond to such emergencies. Much of this large increase in spending was in the form of direct transfers to states and cities through several grant programs. Homeland Security grants may be used for protection against terrorist activities, thereby enhancing public interests, or as wealth transfers to state and local governments, enhancing the reelection efforts of incumbents, and thus, private interests. Using 2004 per capita Homeland Security grant funding to states and their cities, we find that the funding formula used for some of the grant programs, which allocates almost 40% of the funds in some grant programs through a minimum percent to each state with the rest allocated based on population, means that per capita funding is related to electoral votes per capita, i.e., to the politics of Presidential re-election. However, the funding in other grant programs is also related to some of the dangers and vulnerabilities faced by states and their cities. Some of the variation in per capita grant allocations is also explained by the amount of airport traffic in the state and the state's population density, which are variables closely linked to the state's vulnerability to attack. Per capita Homeland Security grant allocations, however, do not seem to be related to the closeness of the 2000 presidential race.  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

Abstract After a discussion of possible components in a definition of 'cumulation' and the relative lack of cumulation in political science, a scheme for research strategies is outlined with the aim of facilitating cumulation, or at least facilitating a diagnosis of the state of political science in this respect. The scheme includes three types of studies: (1) analysis of the formal properties of theoretical approaches in political science, (2) content analyses in the form of inventories of problems, propositions and concepts in the discipline, (3) evaluational analysis, i.e. an assessment of what 'theory criteria' to use for evaluating the approaches and of the probable relations between these criteria.  相似文献

An intoxication following administration of morphine, tramadol and atracurium in a suicide case is reported. The route of administration and the amount of the particular drug were known from the investigation of the death scene and the findings of the postmortem examination. Tramadol was present in the gastric contents as well as in blood, liver, kidney and brain samples, whereas the drug could not be detected in muscle. All body fluids and tissues investigated contained morphine as well as its 3- and 6-glucuronides with the exception of muscle tissue. The concentrations of morphine and its glucuronide metabolites were determined by LC/MS following solid phase extraction. Interestingly, the concentration of M6G in brain, liver and kidney were close to the concentration of M3G in the particular tissue. This phenomenon might be explained by a preferential hydrolysis of M3G or by a preferential formation of M6G postmortem. Measurement of morphine and M6G in femoral blood and cerebrospinal fluid may be a useful indicator in rapid deaths.  相似文献

A 40 year-old woman was killed by fist and chop blows and buried in a forest area far away from the scene of the homicide. Before covering the body with soil the perpetrator poured 25 kg of tile cement powder over it. When the victim was retrieved 6 weeks later, the cement had hardened covering the body like a plate and encasing it like a sheath. The surface of the tile cement facing towards the body was found to contain two kinds of traces: detailed cast-like reproduction of the textile structures of the victim's clothing and wallpaper-like epidermal adhesions. By means of sequencing the mitochondrial DNA the adherent horny scales could be related to the victim.  相似文献

DNA typing is often used to determine identity from human remains. The environment to which the material has been exposed, however, is crucial for the success of the investigation. Damp conditions in particular can cause a rapid degradation of DNA, even in bone and teeth, and thus reduce the chances of successful typing. Here, we present the results of investigations performed on four skulls that had been lying in a damp environment for periods ranging from almost 1 year to about 45 years. In none of these cases was DNA typing successful on bone or, where present, on teeth. Where remnants of brain tissue were used, however, complete STR typing was possible in one case, partial STR typing in another, and mtDNA sequencing could be carried out in three cases. These findings suggest that brain tissue is relatively resistant to putrefaction in damp environments and, unlike bone, appears to exhibit a certain degree of protection against DNA degradation.  相似文献
