One of the flashpoints of post-socialist life has been the conflict between indigenous peoples and energy developers in the Russian Federation North. As a result of tensions over land and resources, multiple identities and political rivalries have been revealed. Such tensions spark the uncertainties that are not only a hallmark of post-socialism, but also hallmarks of post-colonial and post-welfare societies. The many levels of social interaction in ‘transition societies’ provide a challenge for anthropologists accustomed to focus refined ethnographic lenses at the nomadic camp, village or ‘ethnic’ level. This article covers conflicts of values and expectations for several Siberian groups regarding ecology, land and homeland, as well as cultural rights and revitalisation. Featured cases derive from West Siberia (Yamal and Khanty-Mansi okrug) as well as the Far East (Sakha Republic), and highlight the author's field experience in Siberia for over 25 years. Conclusions urge greater sensitivity to internal debates and trans-national comparisons as we struggle to define a range of analytical categories that both embrace and go beyond ‘post-socialist’ and ‘post-Soviet’ studies. In the process, dilemmas of advocacy are probed, as well as dilemmas of defining ‘homelands’ for indigenous peoples.  相似文献

The number of reports on drug facilitated crimes is increasing these last years. Apart from ethanol and cannabis, benzodiazepines (BZD) and analogs are the most common drugs reported to be used probably due to their amnesic and sedative properties. We have developed a rapid and sensitive method using LC-MS/MS triple stage quadrupole (TSQ) for the determination of single exposure to bromazepam (Lexomil, 6 mg) and clonazepam (Rivotril, 2 mg) in urine and hair of healthy volunteers. Chromatography was carried out on a Uptisphere ODB 5 microm, 2.1 mm x 150 mm column (Interchim) with a gradient of acetonitrile and formate 2 mM buffer, pH 3. Urine was extracted with Toxitube A (Varian) and allowed the detection of bromazepam, 3-hydroxy-bromazepam, clonazepam and 7-Aminoclonazepam for more than 6 days. Head hair, collected 1 month after the exposure, was treated by incubation with Soerensen buffer pH 7.6, followed by liquid-liquid extraction with dichloromethane for common BZD. A specific pre-treatment for amino-BZD, with an incubation of 15 min at 95 degrees C in 0.1 N NaOH before liquid-liquid extraction with dichloromethane, gave better recoveries and repeatability. After single exposure, bromazepam was present in powdered hair at 28 pg/mg and 7-Aminoclonazepam at 22 pg/mg in the first 1-cm segment, while no clonazepam was detectable. This method was applied in two forensic cases. It allowed us to determine bromazepam in urine 3 days after the alleged offense and in cut head hair at a concentration of 6.7 pg/mg only in the 2-cm proximal segment. The other case showed the presence of clonazepam and 7-Aminoclonazepam in urine a few hours after the offense and the presence of 7-Aminoclonazepam at about 3.2 pg/mg in axillary hair 4 months later.  相似文献

This longitudinal study documented the stability of the emotional of a sample of males from adolescence (age 14) through young adulthood (age 19) and into middle adulthood (age 48). Using the Offer Self-image Questionnaire (OSIQ), the Hess and Henry Identity Test, and the Symptoms Checklist (SCL-90), distinct emotional traits were found in 67 adolescent males that were important in determining their mental health status in adult life (age 48). The results clearly demonstrated that certain adolescent emotional states tend to remain a problem in adulthood as well. Intervention work that could be done in order to change any adverse trajectories set by these variables was discussed.  相似文献

Findings from comparisons of joint and sole custody families that do not control for predivorce differences in demographic and family process variables (factors that may predispose families to choose or be awarded joint custody) are of limited generalizability, since obtained group differences may be attributable to predisposing (self-selection) factors, custody, or both. This study compared a random sample of 254 recently separated, not-yet-divorced families on 71 predivorce variables that might plausibly differentiate between families awarded joint legal versus sole maternal custody. Twenty such factors were identified and controlled for in subsequent comparisons of 52 sole maternal and 26 joint legal custody families 2 years postdivorce. Families with joint custody had more frequent father–child visitation, lower maternal satisfaction with custody arrangements, more rapid maternal repartnering, and fewer child adjustment problems (net of predivorce selection factors). Moreover, these effects did not appear to be moderated by level of predecree parental conflict. No association between custody and fathers' compliance with child support orders was obtained.  相似文献

The sentencing decision reflects the culmination of a long series of processing and, thus, selection decisions, with cases leaving the system at each decision point. Accordingly, the substantive implications of bias due to sample selection are of particular concern for sentencing research. In an effort to assess the existence and manifestations of selection bias, the sentencing decision is modeled for three samples, each of which was selected from different stages of the justice process. Event-history data on felony arrests in the State of California over a 3-year period are used, along with a relatively simple analytic technique which reduces such bias. Results indicate that biasis introduced when censored observations are excluded from the analyses. Also, the effects of certain exogenous variables on sentence length differ, depending upon the selection criteria. Of these, the influence of pleading guilty rather than going to trial is especially interesting. Overall, our findings are consistent with the possibility that selectivity bias has concealed effects of sentence bargaining in some earlier studies.The data utilized in this study were collected and made available by the State of California Department of Justice, Bureau of Criminal Statistics. The Department of Justice bears no responsibility for the analyses or interpretations presented here.  相似文献
