This article addresses the relationship between scientific expertise and policy in European chemicals regulation. We argue that the role of scientific expertise in the European regulation of chemicals varies across decision‐making levels, countries, and stages of the policy process. Our case study of the role of scientific expertise in the regulation of brominated flame retardants illustrates considerably different manifestations of this interconnected process across regulatory arenas, even though this case concerns a single group of substances. On the European Union level, we find a mix of technocracy and politicization; in Sweden, a clear‐cut politicization; and in Poland, noninvolvement. Such differences can be explained by a combination of factors, in particular frame dominance, and mobilization of advocacy coalitions. 相似文献

Current cyberbullying literature lacks longitudinal studies clarifying its predictors and consequences. This 1-year longitudinal study investigated how social and emotional competencies develop according to Portuguese middle school students’ involvement in cyberbullying, and whether class size influences this relationship. There were 455 participants (Mage?=?12.58; SD?=?0.94; 46% girls), and data collection through self-reports took place in three different moments during 12 months. The results showed that students involved in cyberbullying in any role displayed negative trajectories during 1 year in self-control and social awareness, while victims and bully-victims displayed a more pronounced decrease in self-esteem and relationship skills during the same period. Additionally, girls displayed higher initial social awareness levels, while larger classes were associated with higher levels of self-control and responsible decision making. These results supported the importance of conducting longitudinal research and using a multilevel approach to address this topic. 相似文献

In the forensic literature, peculiar and uncommon cases of suicides defined as “complicated” are reported. In these circumstances, the suicide method chosen by the victim fails, and death occurs due to a subsequent unforeseen accidental event defined as secondary trauma. Through retrospective examination of 25,512 autopsies in 27 years (1993–2019) at the Bureau of Legal Medicine of Milan, a unique case of complicated suicide was identified from a total of 4497 suicides. It concerns an elderly man who, after killing his wife by inflicting incised wounds to her neck, tried to hang himself by tying a rope to a heater and jumping from the window located over the heater itself. However, the rope suddenly snapped and the man fells to the ground causing fatal traumatic injuries. Death occurred because of an accidental event caused by the failure of the hanging mechanism. Therefore, a peculiar yet characteristic case of complicated suicide is described. 相似文献

In forensic medicine, specialists might face difficulties when estimating age at death from fetal remains. Depending on the state of preservation, this age assessment is essentially based on the diaphyseal size of long bones. In a previous work, for the measurement of fetal femoral ossified shafts, we already established a simple and reliable method using a radiographic protocol. Since we previously stated that radiographic measurement values were closer to real anatomical size than ultrasonographic ones, in the present study we decided to check the importance of the difference between radiographic and anatomical measurements. Therefore, we dissected 30 pairs of fetal femurs and compared the difference between the two kinds of measurements (in percentages). This difference seemed to be slight (4.027%), but it was large enough to entail significant differences (p < 0.001). In order to provide a correction factor for radiographic measurements, we established a linear regression formula, which was tested on another sample of 30 pairs of dissected femurs. As a consequence of the good results, we improved the linear regression using a powerful statistical tool: the bootstrap. Finally, we obtained a simple equation that allowed us to figure out the real anatomical size with an R2 of 99% and a mean relative difference of 0.153% (with a standard error of 0.252 mm, and therefore a 95% confidence interval with limits of -0.35 and 0.657 mm). This difference did not entail any significant differences (p = 0.498), and therefore, we concluded that with the proposed correction, radiographic measurements can easily be used by forensic specialists in their daily tasks or to establish new growth standards in order to best fit their population of interest. 相似文献

Several academic studies on African and Afro-descendant population in Argentina have made reference to the ‘oblivion’ of the black component in the creation of an ethnically white and homogeneous national collective. The present work intends to rethink this issue in light of an Anthropology of the memory that promotes a critical analysis of the construction of an African past as diacritic of ethnic identification and interaction strategy related to the largest society, paying special attention to the actions of ethnic leaderships in the Afro community. In other words, we consider the processes of creation and validation of a social memory from an African origin by the ethnic entrepreneurs. For that purpose, we conduct a qualitative study employing the techniques characteristic of anthropological ethnography. 相似文献

This paper examines the UN 2000 Trafficking Protocol in the context of international responses to the issue of people trafficking. Attention is drawn to the conceptual flaws in this new instrument regarding the failure to address domestic trafficking, not incorporating the purchasing and selling of people as defining characteristics of trafficking, and the lack of clarity around issues of prostitution. Framing the discussion within feminist theory, the essay concludes that women’s campaigning will continue to be crucial to putting issues such as human trafficking on the international political agenda. This is extended to affirm that people’s struggle against oppressive circumstances will lead the tackling of the underlying causes of trafficking. 相似文献

The protection of rights of freedom of speech and assembly for gays and lesbians in Poland has come under greater international
scrutiny because of the mismanagement of peaceful demonstrations throughout Poland in 2005. An overview and context of the
political, economic, and social transformation of Poland in the 1990s shows a flourish of activity among gays and lesbians
as the economic and political spheres open, as well as weaker law enforcement during the rapid change to capitalism and democracy.
Although society has opened dramatically and tolerance has grown recently, the concept of protecting minority rights for gays
and lesbians in Poland continues to be weak in public opinion, laws, and the top sources of opinion.

The aim of this study was to assess the effectiveness of two current on-site oral fluid (OF) drug detection devices (OraLab and Dräger), as part of the Spanish participation in the Roadside Testing Assessment Project (ROSITA Project). The study was done in collaboration with the Spanish Traffic Police, in Galicia (NW Spain), during 2004 and 2005. A total of 468 drivers selected at the police controls agreed to participate through informed consent. In addition, saliva samples were collected and sent to the laboratory to confirm the on-site results. For this purpose, two different analytical liquid chromatography–mass spectrometry (LC–MS) methods were used to detect 11 drugs or metabolites in a 300 μL sample. Simultaneous analysis of morphine, 6-acetylmorphine, amphetamine, methamphetamine, MDA, MDMA, MDEA, MBDB, cocaine and benzoylecgonine was carried out using 100 μL of oral fluid, after an automated solid phase extraction. A different LC–MS method was performed to detect Δ9-THC in 200 μL of oral fluid using liquid–liquid extraction with hexane at pH 6. Both methods were fully validated, including linearity (1–250 ng/mL, 2–250 ng/mL) recovery (>50%), within-day and between-day precision (CV < 15%), accuracy (mean relative error < 15%), limit of detection (0.5 and 1 ng/mL), quantitation (1 and 2 ng/mL) and matrix effect. All of the positive cases and a random selection of 30% of the negatives were analyzed for confirmation analysis. Good results (sensitivity, specificity, accuracy, positive predictive value and negative predictive value > 90%) were obtained for cocaine and opiates by OraLab, and for cocaine by Dräger. However, the results for the other compounds could be improved for both detection devices. Differences in the ease of use and in the interpretation mode (visual or instrumental) were observed. 相似文献
