The aspiration of a foreign body is a high-risk event in the life of an infant or toddler, which needs fast clinical diagnosis and therapy. If the respiratory tract is massively obstructed, the aspiration can be fatal, as shown in the case of an 18-month-old child. The little boy choked on a fragment of a hazelnut shell. Besides radiography and bronchoscopy, a CT scan can be of special value to visualize the foreign body. Based on the data obtained, a virtual bronchoscopy can be calculated. Compared with conventional radiography, the advantages of computed tomography are better image quality, higher indicative value and the possibility to exactly localize the foreign body in the respiratory tract. In the presented case, the nutshell could be visualized in the larynx before autopsy. 相似文献

Abstract: While ballistic parameters of vole captive bolt devices have been reported, there is no investigation on their hazardous potential to cause noise trauma. The aim of this experimental study was to measure the sound pressure levels of vole captive bolt devices. Two different shooting devices were examined with a modular precision sound level meter on an outdoor firing range. Measurements were taken in a semi‐circular configuration with measuring points 0° in front of the muzzle, 90° at right angle of the muzzle, and 180° behind the shooting device. Distances between muzzle and microphone were 0.5, 1, 2, 10, and 20 m. Sound pressure levels exceeded 130 dB(C) at any measuring point within the 20‐m area. Highest measurements (more than 172 dB[C]) were taken in the 0° direction at the 0.5‐m distance for both shooting devices proving the hazardous potential of these gadgets to cause noise trauma. 相似文献

In this case study we want to reduce the gap in research on the influence of organized interests at the federal state level. We analyse the “Gesetz zur Stärkung von innerstädtischen Geschäftsquartieren” (INGE) by applying social network analysis and statistical models. First, we show that the set of actors changes compared to the federal level. Second, we find that striving for influence pays off for non-state actors because influential actors find themselves close to the law. Third, we explain the degree of the actors’ influence. An OLS-regression shows that formal resources like governmental power as well as informal resources such as expertise and support increase influence. The use of informal resources is reflected in interactions in communication networks and specific network positions. Furthermore, we discuss this specific process of interaction between state and societal actors from the point of view of democratic theory. 相似文献

The German federal governmental system is conceptualized as a full-fledged two-level system, in which the Länder governments participate in federal policy decisions via the second chamber Bundesrat and in which the stakes of state coalition building are high for the federal parties. Our research question is whether we can find systematic empirical evidence for an influence of federal on state parties to build state governments whose party composition is concordant with federal politics, containing either exclusively federal governmental or non-governmental parties. We answer this question by indirect evidence. We show that such concordant majority coalitions occur above average even if important coalition predictors are controlled as minimal winning coalitions or participation of dominant and/or central players. We predict the 182 actual Land governments which were formed in the period from 1949 to 2003 compared to the possible governments in each situation. 相似文献

This study addresses the hypothesis concerning the ideological convergence of political parties in light of election campaigns in Finland. The basic expectation is that the parties have become more alike in terms of their orientation vis-à-vis the electorate and in their use of propaganda techniques. The empirical data consists of editorials in the leading newspapers of the four largest Finnish parties in connection with the parliamentary election campaigns of 1954, 1966, 1975 and 1987. The main hypothesis is clearly corroborated, as traditional elements such as class orientation have been replaced by references to the nation at large and to the political elite. A re-ideologization could be noted in connection with the 1975 campaign, followed by a strong de-ideologization in 1987. Despite the virtual disappearance of offensive propaganda techniques, recent campaigns were not found to be decisively less 'propagandists' than the earlier ones. 相似文献

The Clean Development Mechanism (CDM), established by the Kyoto protocol, can generate substantial rents for project participants via the sale of Certified Emission Reductions. For this reason, supposedly technical decisions about the approval of CDM methodologies and about the registration of projects may be driven by benefits to specific countries or interest groups. Our econometric analysis of data for about 250 methodologies and about 1000 projects discussed by the CDM Executive Board (EB) so far, suggests that indeed, along with formal quality criteria, political-economic variables determine the final EB decision. 相似文献

This article provides a background for the Developing post-2012 scenarios project, an international study which looks at a range of scenarios that countries may wish to consider for a post-2012 framework to tackle climate change. The purpose of the article is threefold. Firstly, it provides a review of the literature for the future climate regime. Secondly, it provides a set of criteria that are used in order to evaluate whether the scenarios provided in the other articles in this Special Edition are likely to be effective. Thirdly, the article spells out some of the more general policy implications rising from these scenarios. 相似文献
