The article reviews practical experiences and theoretical reflections from the Dutch child and youth care sector on the provision of care for families with multiple problems. Emphasis is laid upon the complex relations between socioeconomic and psychosocial problems, and subsequent issues that may arise in arranging child and youth care. Furthermore, the current state of discussion in program development for the target group in the Netherlands is introduced. The originally English concept of families with multiple problems has been used only modestly in German-speaking countries. This is remarkable from an international perspective, especially considering the re-emerging prominence of social policies that define families as a site of social work practice in English-speaking countries. We conclude that the themes, as derived from our review open up possibilities for further international comparisons, and can provide valuable reference for the transnational discourse about child and youth care services for families with multiple problems.  相似文献

Although researchers have made numerous advances in the understanding of the nature, extent, and dynamics of violence against women (VAW), there is an ever-increasing need for data used in academic research and within policy decision-making to be collected via rigorous methodological designs to accurately measure the incidence and impact of VAW. What is now needed are research collaborations within an interdisciplinary research cluster that will expand understanding of the complex nature of VAW. The current article details an agenda or “call to action” to address deficiencies and advance VAW research, in addition to informing VAW intervention and prevention efforts.  相似文献

Sudden unexplained death in epilepsy occurs when epilepsy patients die suddenly and unexpectedly in the absence of recent tonic-clonic seizure activity. There is currently no known reliable indicator of acutely lethal seizure activity. Clinical studies record a relationship between recent (within 10-40 minutes) seizure activity and elevated serum prolactin levels, and postictal elevation of prolactin within peripheral vessels has proved clinically useful in determining recent seizure activity. The authors hypothesized that elevated prolactin could be detected in cerebral vessels by immunohistochemical stains, serving as a marker for sudden unexplained death in epilepsy. They conducted a retrospective study of individuals who died in their jurisdiction during the 14 years from 1986 through 1999. The study contained one group of individuals who died of sudden unexplained death in epilepsy, a group with epilepsy who died of some other cause, and a control group whose members died rapidly of a gunshot wound of the torso. Sections of hippocampus and neocortex were obtained and stained with a polyclonal prolactin antibody. No significant difference in the level of immunostaining for prolactin in cerebral vessels was found between the experimental and control groups. A review of the protocols used indicates that revision of certain aspects may provide better immunostaining and more conclusive results.  相似文献

Treatment of morphine, at room temperature, with a mixture of trifluoroacetic anhydride (TFAA) and acetic acid (20-30min) affords good yields of heroin. GC-MS and HPLC examination shows that heroin produced by this route to be extremely clean, but the product contains slightly less heroin than observed via the more traditional acetic anhydride (AA) route (76.1% versus 83.55%); and greater quantities of 3-MAM and 6-MAM (6.9% versus 0.75% and 7.13% versus 0.63%). The concentration ratios of the major alkaloid impurities were found to be both production method (TFAA and AA) as well as morphine extraction methodology dependant. Data contained herein describe the impact of this new production method on current intelligence efforts, largely by-passing existing heroin signature programs and the UNDCP's efforts to restrict access to key synthetic precursors. Given the methodology dependency we find that examination of the major alkaloid ratios is unsuitable for the development of a new heroin signature program. Further examination of the TFAA methodology allowed the identification of TFAA specific marker compounds, namely bis-trifluoroacetylmorphine (30), 3-trifluoroacetyl-6-acetylmorphine (31), 3-acetyl-6-trifluoroacetylmorphine (32) and trifluoroacetylcodeine (33). However, the hydrolytic lability of trifluroacetyl esters requires careful treatment of suspect samples, thus we propose a modification to existing HSP's in instances were the 6-MAM/WM ratio falls within the average minimum and maximum values of 6.17 and 17.32.  相似文献

Conclusion Despite partial amendments to criminal legislation the existing Czech criminal system is marked by its punitive character. Despite a slight change in attitudes towards punishment after 1990, the nature of penalties has not been adapted to the new goals. The punishment which fulfils the retributive, i.e. deterrent objective will not automatically become a means of re-education and rehabilitation merely because we change its objective in law. The new purpose of punishment requires changes in contents of punishment, i.e. searching for effective ways of handling offenders both outside and inside prisons. We have to renounce the idea that rehabilitation of offenders can be achieved by coercion. We have to respond to offending by imposing an adequate punishment which must be executed paying full respect to human rights and dignity. In this context, any offender must be able to exercise his or her right to request conditions and means for social reintegration (training, improvement of skills, medical treatment etcetera), if the offender is really interested in rehabilitation. We can only create conditions, we cannot reintegrate anybody by force. Rehabilitation in the Czech Republic continues to be more a good intention than a reality.  相似文献

Conventional approaches towards the impact of corruption on post-conflict stabilization suggest that corrupt practices impede a successful war to peace transition. When transparency and accountability are absent, the risk of corruption threatens to turn the state apparatus into a tool of enrichment for those in power and affect the “exit” from violence/insurgency towards demobilization and reintegration. However, corruption may have redeeming values by serving the function of a power-sharing arrangement between antagonistic parties, thereby, reinforcing peace. Radical anti-corruption programs in post-conflicts situations may bring adverse results such as a renewal of violence. Aimed to fill the void in research on corruption in post-conflict situations, the article inquires about the links between corruption, peacebuilding and violent non-state actors. By combining various disciplinary approaches, the article theorizes the outcomes of corruption in post-conflict situations and discusses them in the context of Kosovo and Chechnya.  相似文献

There is a lack of reliable data on the role of women in transnational organized crime. So far, the focus of this research has overwhelmingly been on the Italian Mafia. Little is known about women’s roles in other types of organized crime activities. Since there is an ongoing perception that draws on stereotypical imagery of women in organized crime as appendixes to their male counterparts, this article explores whether women are indeed as oppressed in transnational organized crime as they are in other spheres of life. It focuses on the stereotypical constructions of femininity (victims) and masculinity (criminals) and argues that hegemonic gender roles are defined by the dominant European/American culture. The article takes a multicultural feminist approach and studies female criminality in the context of “doing gender,” an approach that assumes that the feminine gender role is something that must be accomplished in the context of specific situations. By studying the roles of women from West Africa and the Balkans in transnational criminal activities, it specifically examines how time and space, as well history and culture, contribute to one’s position in a criminal network.  相似文献

Most conventional approaches to the study of arms trafficking are grounded on the assumption that people are rational and always seek the most cost-effective means to achieve a goal. This article discusses the illicit firearms markets in the Balkans and the North Caucasus—the regions in which trafficking of illicit firearms has been flourishing since the early 1990s. By studying the demand side of this illicit market, it provides some possible explanations as to why numerous arms reduction measures have had limited results. It argues that cultural attitudes, socio-political complexity and emotions could explain much of the “irrational” behavior of those demanding weapons in these regions. The article contributes to the scholarly debate on the applicability of the rational choice theory-inspired arms reduction policies in highly textured sociocultural contexts. It is an effort to construct multifaceted conceptualization of human choice that focuses not only on the functionality of firearms but also on their symbolic and situational meaning.  相似文献
