Abstract: Forensic organizations worldwide have recommended that dental prostheses should be labeled with at least the patient's name and preferably with further unique identifiers such as social security number, etc. The practice of denture marking has been conducted over many years and several denture marking systems have been reported in the dental literature. However, very little is known about the resilience of such systems to conditions experienced in the majority of post- and perimortem assaults. The purpose of this investigation therefore, was to expose a selection of 10 denture labels to a series of hostile environments. Results of the study indicate that the majority of the denture labeling systems appear capable of withstanding a range of common, and not so common postmortem assaults. With regard to thermal insult, however, most performed badly with the exception of a label constructed from stainless steel orthodontic band. However, another label in the form of an electronic RFID-tag performed above expectations in the majority of experiments. Furthermore, its cosmetic appearance has proven most popular with many patients. 相似文献
This paper presents the findings of the first major research study of part-time law students. It argues that many face multiple disadvantages, largely unrecognized by universities, whose emphasis on the formal equivalency of part-time and full-time law degrees ignores the distinctive backgrounds and needs of part-time students. As a result, many are marginalized, impacting on their retention, overall performance, and work prospects. It is also argued that the context within which part-time law students experience legal education contributes to a collective habitus which may structure what is 'thinkable' for their futures. Such concerns are of particular importance given the strong vocational drive amongst part-time law students. An effective response requires action by both universities and the legal profession. Without this, part-time legal education will remain a fundamentally paradoxical experience, offering broader access to legal practice for non-traditional entrants, while continuing to inhibit their chances of success by entrenching their difference in the eyes of the profession. 相似文献
In the United States, opioid-related mortality has tripled since 2000, leading the Centers for Disease Control to declare a national overdose epidemic in 2016. With overdose an increasing area of mainstream political and popular concern, some commentators have suggested that sympathetic attention has followed changes in the profile of opioid users, as rates of heroin initiation have doubled among white Americans and women. Yet no studies have examined how media framings of overdose have shifted alongside the epidemic’s demographic contours. Focusing upon southwestern Pennsylvania, this study uses qualitative analysis of news items surrounding three surges in heroin overdose deaths in 1988, 2006, and 2014. 178 items reporting on such overdose outbreaks were selected for thematic coding, with attention directed toward opioid user representations, “drug problem” characterizations, and suggested solutions. Results reveal a transformation in the depiction of overdose sufferers over time, with stories increasingly centered around “unexpected” opioid users, whose habits are made legible through biomedical discourses of addiction; such portraits are used to argue the impropriety of punitive responses to drug misuse. At the same time, the role of criminal justice institutions in addressing overdose is not dismissed, but relocated in recent coverage, with the intensified prosecution of drug dealers offered by many. 相似文献
Preferential Trade Agreements (PTAs) have become the most prevalent form of international trade liberalization in recent decades, even though it remains far from clear what their effects on economies and their key units, firms, are. This paper evaluates the distributional consequences of trade liberalization within industries differentiating two distinct aspects in which trade liberalization could result in higher trade flows: the intensive vs. the extensive margin of trade. In particular, we analyze whether trade liberalization leads to increased trade flows because either firms trade more volume in products they have already traded before (intensive margin) or because they start to trade products they have not traded previously (extensive margin), or both. We test these arguments for the Dominican Republic–Central America–United States Free Trade Agreement (CAFTA-DR) and exporting firms based in Costa Rica for the time-period 2008–2014. The results of our study suggest that the effects of CAFTA-DR depend not only on whether we analyze the extensive versus the intensive margin of trade but also whether the product in question is homogenous or differentiated and whether the exporting firm under analysis is small or large. In particular, we find support for the theoretical expectation that firms exporting heterogeneous products, such as textiles, gain from trade agreements, such as CAFTA-DR, in that they can export more varieties of their products. Yet at the same time, they tend to lose at the intensive margin by a reduction in their trade volume while the opposite pattern occurs for firms exporting homogenous products. 相似文献
The narrative and dual-cycle approach conceptualize and operationalize adolescents’ identity formation in different ways. While the narrative approach focuses on the construction of an autobiographical life story, the dual-cycle approach focuses on the formation of identity commitments. Although these approaches have different emphases, they are conceptually complementary. Yet, their empirical links and distinctions have only scarcely been investigated. Empirical knowledge on these links in adolescence and across time has been especially lacking. In the present research, it was therefore examined whether key characteristics of adolescents’ narration (autobiographical reasoning and agency) were concurrently and prospectively related to engagement in the dual-cycle processes of commitment making, identification with commitment, exploration in breadth, exploration in depth, and ruminative exploration. The findings from a cross-sectional sample of 1,580 Dutch adolescents (Mage?=?14.7 years, 56% female) demonstrated that autobiographical reasoning was significantly positively associated with the commitment and more adaptive exploration processes (i.e., in breadth and in depth). In addition, agency was significantly positively associated with the commitment processes and exploration in depth. Yet, these associations between the narrative characteristics and dual-cycle processes were only weak. Subsequently, the findings from a two-year longitudinal subsample (n?=?242, Mage?=?14.7 years, 62% female) indicated that on average commitment strength remained stable but exploration increased across middle adolescence. A stronger increase in identification with commitment and adaptive exploration (i.e., in breadth and in depth) was predicted by a higher degree of agency in adolescents’ narratives. Overall, these findings indicate that both approaches to identity formation are associated, but the small size of these associations suggests that they predominantly capture unique aspects of identity formation. Both approaches could thus complement and inform each other.
One line of research finds the size of the deficit to be positively correlated with the number of political actors. This ‘political fragmentation’ hypothesis has been tested on OECD countries. We successfully replicate Volkerink and de Haan’s (Public Choice 109:221–242, 2001) model on an OECD sample. However, when we add ten non-OECD countries, the effect of political fragmentation disappears. We argue that the importance of political fragmentation varies according to the institutionalization of political systems. When we interact the age of a democracy with political fragmentation, we find that legislative fractionalisation increases the budget deficit as a democracy becomes more institutionalised. 相似文献
