This study highlights the problem of levamisole‐adulterated cocaine in context of active traffic participation. For the purposes of levamisole concentration monitoring in human serum, an analytical method based on LC‐MS/MS and solid‐phase extraction was applied. A Luna 5 μm C18 (2) 100 A, 150 mm × 2 mm column and a mobile phase consisting of A (H2O/methanol = 95/5, v/v) and B (H2O/methanol = 3/97, v/v), both with 10 mM ammonium acetate and with 0.1% acetic acid (pH = 3.2), were used. The validation experiments demonstrated that the method applied was appropriate for levamisole quantification in human serum. For 23% of levamisole‐positive samples, the concentrations exceeded 20 ng/mL. Therefore, the interaction of this drug with cocaine has to be considered as important for active traffic participation. As a consequence, monitoring of levamisole concentration in human serum is recommended, as long as it is used as cocaine adulterant.  相似文献

School can be regarded as an important factor in the development of children’s values and attitudes. Given this great importance of justice experiences for students’ development, this study aimed at examining the influence of perceived injustice in school on students’ emotions, well-being, and behavior with an experimental longitudinal design. In total, 196 students participated in this study and came to the university with their classes to receive extra teaching once a week for six consecutive weeks. To manipulate justice perceptions, a scenario of arbitrary privilege was chosen to lead students of the experimental group to experience injustice from a beneficiary perspective. We found that students in the experimental group reported higher well-being and a higher appreciation of the opportunity to learn than the control group did. Additionally, they showed an increase in justice-related negative emotions over time; that is, they expressed more of a bad conscience and stronger feelings of anger the more they became aware of their privilege. This study shows that even subtle experiences of injustice in school can have an impact on students’ outcomes. These results are discussed with regard to practical implications.  相似文献

The difference in official crime statistics between women and men is a constant fact in criminology, but has yet to be explained in a satisfactory way. There are few studies addressing the issue of why this gender gap is larger in registered crime than it is in self-report studies. The study at hand comprises a survey among Greek and German students to examine whether this gap could be attributed to a gender-specific reporting of crime. Participants’ self-reported experiences of victimisation and their rating of the seriousness of offences depicted in case vignettes were used to gain insight into varying tendencies to report a crime depending on the offender’s gender. The act of reporting a crime did not vary gender-specifically.  相似文献

Produced water should be viewed as an environmental asset—part of the water resource solution—not as a waste that contributes to environmental problems; its treatment and reuse can reduce the stress on fresh water resources. Treatment cost is the most significant factor determining the volume of produced water that will be available for reuse. Water pricing, which is in large part a matter of public policy, must also be considered when reexamining how to maximize the use of this valuable resource. When deciding whether to treat and use produced water companies will need to weigh the risk of litigation and regulatory enforcement actions against the benefits of introducing treated water into the stream of commerce. Allaying the public's fear of chemicals in the water supply is also a significant factor in determining whether produced water is viewed as part of a water resource solution or as a waste by-product.  相似文献

In England and Wales, prisoners with mental disorder of such severity as to warrant inpatient treatment may be transferred to hospital under the Mental Health Act. UK Government guidance recommends that this process should be completed within 14 days; however, evidence suggests that in many cases it can take much longer. This retrospective service evaluation of 64 male prisoners, who were transferred under Section 47 or Section 48, aimed to evaluate transfer durations. The mean time from referral to admission was 76 days. Prisoners with a psychotic disorder were admitted more quickly. Remand prisoners were admitted more quickly than sentenced prisoners. Findings suggest that, in the UK the transfer time of prisoners under Sections 47 and 48 of the Mental Health Act continues to far exceed the 14-day target which raises concern about equivalence of care for prisoners. Our findings support arguments for fundamental amendments to the admissions process.  相似文献

In this article, I comment on Simester and von Hirsch’s theory of criminalization and discuss general principles of criminalization. After some brief comments on punishment theories and the role of moral wrongdoing, I examine main lines of contemporary criminalization theories which tend to focus on the issues of harm, offense, paternalism and side-constraints. One of the points of disagreement with Simester and von Hirsch concerns the role of the harm principle. I rely on a straightforward normative concept of “rights of others,” not in the sense of rights granted in positive law but in the sense of rights which are to be justified in political philosophy. With a rights-centered rather than a harm-centered approach, a prima facie reason for criminalization is the violation of others’ rights. It is unnecessary to develop a separate category of “offense to others,” and paternalistic interventions can be criticized straightforwardly because rights can be waived.  相似文献

During the First World War, a primary domestic political aim for all belligerent countries was to preserve the socio-economic status quo in order to provide appropriate conditions for the survival of the state. Therefore, war governments paid particular attention to the maintenance of internal order. While doing this, the central authority of governments became paramount and this situation had remarkable repercussions on state–society relations. This article examines the wartime public order policies of the Ottoman government specifically concerning the Ottoman Greeks (Rum) and Armenians living in Istanbul. During the Great War, these non-Muslim elements were officially regarded as ‘suspects’, in other words, as ‘potential political criminals’ threatening the internal order of the capital. To control the Ottoman Greeks and Armenians, the war government implemented a number of policing strategies that consisted of deportation of individuals and groups, strict control on travel, and close surveillance of ‘suspects’.  相似文献

By comparing the decisions of various meetings of the General Councils of Edirne and Ankara provinces from 1283 to 1288 (1867–1872 AD), this study analyses social and economic dynamics of both provinces, the state vocabulary for handling local demands, and the boundaries of responsibility for the state and the local actors in provincial administration. Instead of reading the Tanzimat as a top-down imposition, this article defines General Councils as sites of negotiations between state and local actors and instruments for local development. This article challenges the conventional view of provincial councils as weak and unable to implement various policies. It contributes to a new generation of studies that challenges the separation between state and social forces and looks at how both interacted in provincial administration.  相似文献

In several recent initial public offerings in privatization casesshares seemed to be severely underpriced. In this paper weprovide a political economy explanation for this apparentunderpricing. Using a variant of Grossmann and Helpmann's (1996)model of special interest politics, we demonstrate thatgovernments may raise their election chances by rationinginvestors because the resulting broader distribution of sharesmakes regulation that is favorable to the privatized firm morepopular. Somewhat surprisingly, even revenues from theprivatization can be increased through rationing. The model alsoexplains the common practice of bonus systems designed to preventinvestors from taking profits immediately.  相似文献
