In the current public discourse the phenomenon of insecurity is widely discussed since various kinds of social risks are becoming more widespread throughout European societies threatening biographical stability and status security. Given this there is a quest for a realignment of state interventions aiming at the (re-)production of stability and security. It is assumed that institutional arrangements and interventions such as employment protection, income maintenance schemes and healthcare provision not only contribute to objective but also to subjective security. Using data from the European Social Survey 2008 for the labor force in 20 European nations, we test this assumption by scrutinizing three kinds of perceived social risks: the risk of job loss, the risk of lack of monetary means and the risk of insufficient healthcare provision. We take on a cross-national perspective and conduct ordinal multi-level regression analyses in order to measure the extent to which different levels of social policy interventions can be accounted for differences in subjective insecurity. We find that a high degree of employment protection??astonishingly??does not enhance the perceived employment security significantly, whereas higher levels of social security spending and healthcare expenditure indeed go along with higher levels of subjective security. This relationship is moderated by the general level of economic development.  相似文献

This article considers the challenges of promoting children's participation in development programming. It argues against the tendency to see the main obstacle to achieving this aim as technical. Instead it explores the institutional dimensions of change that may be required. The experience of a four-year process of training and organisational review within Save the Children Denmark provides the substance for reflection about the kinds of cultural and structural change that are implicated in enabling a development organisation to become capable of engaging young people as stakeholders in a meaningful and sustainable manner.  相似文献

Abstract: Secondary dentine is responsible for a decrease in the volume of the dental pulp cavity with aging. The aim of this study is to evaluate a human dental age estimation method based on the ratio between the volume of the pulp and the volume of its corresponding tooth, calculated on clinically taken cone beam computed tomography (CBCT) images from monoradicular teeth. On the 3D images of 111 clinically obtained CBCT images (Scanora®3D dental cone beam unit) of 57 female and 54 male patients ranging in age between 10 and 65 years, the pulp–tooth volume ratio of 64 incisors, 32 canines, and 15 premolars was calculated with Simplant® Pro software. A linear regression model was fit with age as dependent variable and ratio as predictor, allowing for interactions of specific gender or tooth type. The obtained pulp–tooth volume ratios were the strongest related to age on incisors.  相似文献

This article examines organized efforts by citizens to provide medical aid to unauthorized migrants in Germany. A case study of an activist organization in Berlin highlights how prevailing forms of governance through citizenship are disrupted. Three major themes are explored. First, historical contingencies and policy realities explain why, given examples of grassroots protest by migrants in other settings, efforts in Germany have been driven primarily by citizens. Second, migrants' biolegitimacy shapes specific ideas of relative deservingness. As a result, advocacy for some groups, such as survivors of torture or refugees from specific geopolitical settings, is more highly valued than that which addresses needs of unauthorized labor migrants. Finally, although their sustained efforts have resulted in challenges to policy and called into question prevailing notions of citizenship, medical activist organizations have become increasingly institutionalized, which may jeopardize their goals. As this case illustrates, the distinctive ethics associated with providing medical care has the ability to disrupt the scaling of citizenship by the state by treating noncitizens – especially ‘illegal’ noncitizens – ostensibly as citizens, thus protesting citizenship as the exclusive organizing principle of German society.  相似文献

The Finnish electoral system has recently been changed to slightly increase proportionality, but nothing has been done to make cabinet alternatives more ‘identifiable’ before the election. This outcome poses a major puzzle for one important theoretical approach to electoral system change. This approach sees normatively ‘unbalanced’ systems as vulnerable to reform and would have expected a significant increase in the pre-electoral identifiability of competing cabinet options. The article explains the Finnish case by embedding it in a comparative model of normative tradeoffs in democratic design. Based on Finnish case evidence and a statistical analysis of 100 elections in 32 democracies (from 2001 to 2011), the article argues that the type of democracy exemplified by Finland is not normatively unbalanced. In particular, the lack of pre-electoral identifiability is compensated for by an unconstrained multidimensionality of partisan preferences. While it may be true that normatively balanced designs are more stable, there is more than one way to be balanced.  相似文献

Abstract:  The radiological determination of foreign objects in corpses can be difficult if they are fragmented or deformed. With multislice computed tomography, radiodensities—referred to as Hounsfield units (HU)—can be measured. We examined the possibility of differentiating 21 frequently occurring foreign bodies, such as metals, rocks, and different manmade materials by virtue of their HU values. Gold, steel, and brass showed mean HU values of 30671–30710 (upper measurable limit), mean HU values for steel, silver, copper, and limestone were 20346, 16949, 14033, and 2765, respectively. The group consisting of objects, such as aluminum, tarmac, car front-window glass, and other rocks, displayed mean HU values of 2329–2131 HU. The mean HU value of bottle glass and car side-window glass was 2088, whereas windowpane glass was 493. HU value determination may therefore help in preautopsy differentiation between case-relevant and irrelevant foreign bodies and thus be useful for autopsy planning and extraction of the objects in question.  相似文献

The increasing involvement of girls under 18 in violent crime has been a matter of growing concern in the United States in recent years. This article reviews the arrests of female juveniles for violent crime and then focuses specifically on their involvement in homicide. Arrests of girls for murder, unlike arrests for assault, have not risen over the last 30 years, suggesting that the dynamics that propel female juveniles to engage in lethal violence differ from those contributing to assaultive behavior by this same group. A review of the literature indicates that theories as to why female adolescents kill do not take into account recent scientific findings on brain development and the biological effects of early trauma in explaining serious violent behavior by girls. Three cases, evaluated by the authors, involving female adolescents charged with murder or attempted murder, are presented. The authors focus on the biological and psychological dynamics that help explain their violent behavior. They discuss the effects of insecure attachment and child maltreatment, and trace a critical pathway between these early experiences and future risk of violent behavior. The dynamics of child maltreatment in fostering rage and violence are discussed thereafter in terms of offender accountability. The article concludes with a discussion of treatment and recommendations for future research.  相似文献
