An ink dating method based on solvent analysis was recently developed using thermal desorption followed by gas chromatography/mass spectrometry (GC/MS) and is currently implemented in several forensic laboratories. The main aims of this work were to implement this method in a new laboratory to evaluate whether results were comparable at three levels: (i) validation criteria, (ii) aging curves, and (iii) results interpretation. While the results were indeed comparable in terms of validation, the method proved to be very sensitive to maintenances. Moreover, the aging curves were influenced by ink composition, as well as storage conditions (particularly when the samples were not stored in “normal” room conditions). Finally, as current interpretation models showed limitations, an alternative model based on slope calculation was proposed. However, in the future, a probabilistic approach may represent a better solution to deal with ink sample inhomogeneity. 相似文献

Using multilevel modeling, this study examined how different types of bullying, involving both peers and teachers, relate to psychosomatic health complaints. Data were obtained via the Stockholm School Survey from 41,032 ninth- and eleventh-grade students in the years 2004, 2006, 2008, and 2010. Results showed that students involved in bullying as either a bully, a victim, or both a bully and a victim displayed poorer psychosomatic health than those not involved in bullying. Victims of peer-bullying also reported significantly poorer health than perpetrators. Two class-aggregated measures of bullying remained positively associated with ninth-grade student health complaints even when their individual-level analogues were taken into account. Thus, both the proportion of victims of teacher-bullying and peer-bullying in the school class appeared to generate health problems that go beyond the directly exposed students. However, an interaction revealed that the latter association was confined to female students only. 相似文献

Institutional Characteristics and Regime Survival: Why Are Semi‐Democracies Less Durable Than Autocracies and Democracies?

Previous studies report that semi‐democratic regimes are less durable than both democracies and autocracies. Still, mixing democratic and autocratic characteristics need not destabilize regimes, as three highly plausible alternative explanations of this correlation remain unaccounted for: (a) semi‐democracies emerge under conditions of political instability and social turmoil; (b) other regime characteristics explain duration; and (c) extant democracy measures do not register all regime changes. We elaborate on and test for these explanations, but find strikingly robust evidence that semi‐democracies are inherently less durable than both democracies and autocracies. “Semi‐democracies are particularly unstable political regimes” should thus be considered a rare stylized fact of comparative politics. The analysis yields several other interesting results. For instance, autocracies and semi‐democracies are equally likely to experience “liberalizing” regime changes more specifically, and once accounting for differences in degree of democracy, there is no robust evidence of differences in duration between military and single‐party regimes. 相似文献

Recent research suggests that youths interpret parental control and that this may have implications for how control affects
youths’ adjustment. In this study, we propose that youths’ feelings about being over-controlled by parents and feeling connected
to parents are intermediary processes linking parental control and youths’ adjustment. We used three years of longitudinal
data sampled from 1,022 Swedish youths in 7th, 8th, and 9th grade (47.3% girls; 12–17 years old, M age = 14.28 years, SD = .98) who were mainly Swedish in ethnic origin. We tested models linking parental control (i.e., rules,
restriction of freedom, and coldness-rejection) to adjustment (i.e., norm-breaking, depressive symptoms, and self-esteem)
through youths feeling over-controlled by and connected to parents. The overall model incorporating youths’ feelings showed
that restrictions and coldness-rejection were both indirectly linked to increases in norm-breaking and depressive symptoms
through increases in youths feeling over-controlled. Parental rules still independently predicted decreases in norm-breaking
and in self-esteem, and coldness-rejection predicted increases in norm-breaking. In addition, some paths (e.g., feeling over-controlled
to self-esteem) depended on the youths’ age, whereas others depended on their gender. These results suggest that when youths’
feelings are taken into account, all behavioral control is not the same, and the line between behavioral control and psychological
control is blurred. We conclude that it is important to consider youths’ feelings of being controlled and suggest that future
research focus more on exploring this idea. 相似文献

Negative physical and psychological long-term consequences of abuse and bullying are well documented. It is reasonable to assume that abuse and bullying early in life also may have an impact on the ability to work and stay economically independent later in life, but such prospective studies are lacking. This study investigates the consequences of exposure to abuse and bullying in junior high school, as measured by receiving long-term social welfare benefits in young adulthood. In addition, it explores the potential protective role of social support. Self-reported data from 13,633 (50.3 % female) junior high school students were linked to registry data on their use of social welfare benefits from the age of 18 and for eight consecutive years. Cox regression analyses were applied to test the relationship between exposure to life adversities and the use of social welfare benefits, and the potential moderating role of social support. The analyses showed that individuals exposed to abuse and bullying had an increased likelihood of receiving social-welfare benefits compared with individuals not exposed to these types of abuse. Exposure to multiple types of abuse led to a higher likelihood of using social welfare benefits compared with single types of abuse and no abuse. The findings on the potential moderating role of social support were mixed, depending on the source of social support. Family support and classmate relationships were protective in reducing the likelihood of the use of social welfare benefits, whereas peer and teachers’ support showed inconsistent patterns. These results are promising in terms of preventing the long-term negative consequences of abuse and bullying. 相似文献

In this article, we use in-depth interviews with young adults in Sweden to explore the gendered and embodied experiences of depression and antidepressant use. Building upon previous phenomenological research, we analyse being depressed and on antidepressants as altered embodied states, in which corporealization—experiencing the body as a material object—is central. Feminist interventions by Toril Moi and Iris Marion Young inform our analysis of embodiment as gendered. The bodily facets of depression include the weight of the anxious body in crying and not sleeping, as well as the weakened or distorted relationship between body, mind and world in brooding thoughts and hopelessness. These experiences of corporealization are not expressed in gendered terms but, when acted out in depression, they do appear to be gendered. The female body becomes “the first battleground”—as the socially endorsed object upon which to act destructively. In contrast, male behaviour is not expressed as self-destructive, but projects in the world are emphasized at the cost of (bodily) well-being. Although antidepressants lift the corporeal weight of anxiety and low mood, they install a new, and in some respects more profound, corporealization of the body. This is expressed as feeling and caring less and being like a thing or machine. It can be understood in terms of an increased distance from the world—not articulated in gendered terms. As a way of existing in the world, the medicated state bears strong similarities to the depressed state from which it was originally an effort to escape. Thus, taking medication can be seen as yet another way of acting on the body as object. Furthermore, it could be suggested from our findings that when the body is not felt—when there is a breakdown of the meaningful relationship between the body and the world—the experience is less gendered. 相似文献

Forty years after the beginning of the Khmer Rouge regime, the recent Trial Chamber judgment in case 002/01 before Extraordinary Chambers in the Courts of Cambodia (ECCC) has provided legal recognition of the devastating violence of the forced population movements. However, despite the undoubted significance of the judgment, it represents a missed opportunity to more fully reflect issues of gender. The article argues that in order to capture the plurality of gendered experiences it is necessary to foreground a social understanding of harm. Drawing on civil party oral testimony, the article begins to surface gendered experiences of the social harms of familial separation and starvation of family members, harms that have often remained silenced in international criminal law. In doing so it seeks to contribute to emerging feminist discourse on broader gendered harms and illustrates the need for further scrutiny of the approach of the ECCC. 相似文献

It is now clear that the global shift toward democracy in recent decades has resulted in a highly uneven democratic landscape in which the quality and performance of democracies around the world vary greatly. In an era characterized by increasingly open borders to goods, services, information, and, at times, labor, we argue that poorly performing, uneven democracies have become an important, yet underexplored, component in one’s emigration calculus. We test this argument through analysis of survey data across 22 Latin American countries and find strong and consistent evidence that both the quality of a democratic system and its ability to fulfill basic governance responsibilities influence the degree to which an individual considers emigration as a viable life strategy. These findings in turn have implications for the subsequent impact emigration may have on the democratic development of high migration communities. 相似文献
