Although media exposure has been related to cognitive preoccupation with appearance, research rarely investigated adolescents’ behavioral self-sexualization. To address this gap, the present study among 12- to 16-year-olds (N?=?1527; 50.2% girls) in Austria, Belgium, Spain, and South-Korea (1) investigates whether different types of media use relate to self-sexualization, (2) explores the explanatory value of rewarded appearance ideals, and (3) considers culture and gender as moderating factors. Despite cultural variation, a general trend of increasing self-sexualization with social media use and magazine reading appeared across the countries. Moreover, women’s magazine reading and rewards were related to self-sexualization among all the girls across the countries, which suggests that girls may be more vulnerable to the examined effects. Overall, this study provides a better understanding of the unique contribution of specific media genres to youth’s self-sexualization and points at the importance of social media use in girls’ and boys’ engagement in sexualizing appearance behaviors across four countries.  相似文献

An increasing number of citizens change and adapt their party preferences during the electoral campaign. We analyze which short-term factors explain intra-campaign changes in voting preferences, focusing on the visibility and tone of news media reporting and party canvassing. Our analyses rely on an integrative data approach, linking data from media content analysis to public opinion data. This enables us to investigate the relative impact of news media reporting as well as party communication. Inherently, we overcome previously identified methodological problems in the study of communication effects on voting behavior. Our findings reveal that campaigns matter: Especially interpersonal party canvassing increases voters’ likelihood to change their voting preferences in favor of the respective party, whereas media effects are limited to quality news outlets and depend on individual voters’ party ambivalence.  相似文献

The rapid further development of computed tomography (CT) and magnetic resonance imaging (MRI) induced the idea to use these techniques for postmortem documentation of forensic findings. Until now, only a few institutes of forensic medicine have acquired experience in postmortem cross-sectional imaging. Protocols, image interpretation and visualization have to be adapted to the postmortem conditions. Especially, postmortem alterations, such as putrefaction and livores, different temperature of the corpse and the loss of the circulation are a challenge for the imaging process and interpretation. Advantages of postmortem imaging are the higher exposure and resolution available in CT when there is no concern for biologic effects of ionizing radiation, and the lack of cardiac motion artifacts during scanning. CT and MRI may become useful tools for postmortem documentation in forensic medicine. In Bern, 80 human corpses underwent postmortem imaging by CT and MRI prior to traditional autopsy until the month of August 2003. Here, we describe the imaging appearance of postmortem alterations--internal livores, putrefaction, postmortem clotting--and distinguish them from the forensic findings of the heart, such as calcification, endocarditis, myocardial infarction, myocardial scarring, injury and other morphological alterations.  相似文献

Spontaneous pneumomediastinum commonly occurs in healthy young men or parturient women in whom an increased intra-alveolar pressure (Valsalva maneuver, asthma, cough, emesis) leads to the rupture of the marginal pulmonary alveoli. The air ascends along the bronchi to the mediastinum and the subcutaneous space of the neck, causing cervico-fascial subcutaneous emphysema in 70-90% of cases. Ninety-five forensic cases, including five cases of hanging, were examined using postmortem multi-slice computed tomography (MSCT) and magnetic resonance imaging (MRI) prior to autopsy until December 2003. This paper describes the findings of pneumomediastinum and cervical emphysema in three of five cases of hanging. The mechanism of its formation is discussed based on these results and a review of the literature. In conclusion, when putrefaction gas can be excluded the findings of pneumomediastinum and cervical soft tissue emphysema serve as evidence of vitality of a hanged person. Postmortem cross-sectional imaging is considered a useful visualization tool for emphysema, with a great potential for examination and documentation.  相似文献

The body of a 44-year-old scuba diver was examined using postmortem multislice computed tomography (MSCT) and magnetic resonance imaging (MRI), and findings were verified by subsequent autopsy. The goal was to find out whether the important pathomorphological findings for the reconstruction of events and the identification of cause and manner of death could be identified using modem digital cross-sectioning techniques. The findings of a massive vital decompression with pulmonary barotrauma and lethal gas embolism were identified in the radiological images. MSCT and MRI were superior to autopsy in the demonstration of the extent and distribution of gas accumulation in intraparenchymal blood vessels of internal organs as well as in areas of the body inaccessible by standard autopsy.  相似文献

In forensic autopsies, one of the most important and common signs of violence to the neck is hemorrhages of the soft tissues. The Institute of Forensic Medicine in Bern evaluates the usefulness of postmortem multislice computed tomography (MSCT) and magnetic resonance imaging (MRI) of forensic cases prior to autopsy. The aim of this study was to prove the sensitivity of postmortem MSCT and MRI in the detection of hemorrhages of the neck muscles. A full body scan prior to and a detailed scan of the explanted larynx after autopsy were performed. MSCT detected multiple fractures of the larynx. Detailed MRI was able to demonstrate the hemorrhage of the left posterior cricoarytenoid muscle. The minor hemorrhage of the right posterior cricoarytenoid muscle could not be detected with certainty. Although more experience is required, we conclude that combined MRI and MSCT examination is a useful tool for documentation and examination of neck muscle hemorrhages in forensic cases.  相似文献

Recently, a growing number of researchers claim that income is only one dimension of social inequality. Neglecting wealth as a more profound measure of an entity??s financial situation can lead to a misleading or even wrong understanding of social inequalities. This article examines the relationship between income and wealth among elderly people in 13 European countries and tries to answer the following two research questions: Are the income-rich also the asset-rich? And what is the composition of wealth within different income groups? The analyses show that higher wealth often goes along with higher income, whereas a high income does not necessarily correlate with high wealth. Instead, in relation to the amount of wealth they possess, the asset-rich do not dispose of a high income. This may be an indicator that income is not the most important mechanism for the accumulation of wealth in the upper part of the wealth distribution. In general the wealth portfolio of asset-rich households is much broader and therefore less ??crises-prone?? than of the asset-poor. Homeownership is the central component in the wealth portfolio of households. For the lowest income quartiles it is often the only meaningful asset. Summing up, the previous income-based definition of poverty and wealth proves to be inadequate. Analyzing wealth in addition to income, it may turn out that the often proclaimed problem of old-age poverty has been either under- or overestimated.  相似文献

Abstract

The article examines the emergence of governmental bioethics in Great Britain, France and Germany, i.e. bodies, discourses and procedures meant to guide policy-making in terms of ethical considerations. It argues that governmental bioethics, marked by openness, transparency and participation, can be understood as a form of reflexive government in the realm of science governance. It grew out of the problematization of older forms of science governance based on ideas of effectiveness, scientific expertise and system stability, and operates through structuring and managing proper talk rather than intervening in processes of techno-scientific development. Yet, rather than challenging the commitment to techno-scientific ‘progress’, it stabilizes it through mechanisms of inclusion, involvement and mobilization: within the framework of proper ethical talk, participation can be employed to pursue rather than oppose system stability.  相似文献

Abstract: We have developed a concept to enable the analyzing of degraded stains with limited DNA template quantity. Therefore we have constructed a short tandem repeat (STR) multiplex including the German DNA database systems (Q8). The amplicon lengths are smaller than 280 bp. For the validation of Q8 over 50 degraded samples were investigated. Amplifications were performed with “low copy number” PCR, the number of PCR cycles was increased to 33 and the reaction volume was decreased to 12.5 μL. Compared with the MPX2 and Nonaplex kit, the average success rate was increased using the Q8 kit by approximately 20% and 30%, respectively. The efficiency of a sensitive STR multiplex with reduced amplicon lengths was confirmed in comparing the success rates of Q8 for typing degraded samples and samples with limited amount of DNA template while partial profiles were observed with the majority of the samples using commercially available kits.  相似文献
