Sleep Disturbance and Depressive Symptoms in Adolescence: The Role of Catastrophic Worry

Depression is a common and debilitating disorder in adolescence. Sleep disturbances and depression often co-occur with sleep disturbances frequently preceding depression. The current study investigated whether catastrophic worry, a potential cognitive vulnerability, mediates the relationship between adolescent sleep disturbances and depressive symptoms, as well as whether there are gender differences in this relationship. High school students, ages 16–18, n = 1,760, 49 % girls, completed annual health surveys including reports of sleep disturbance, catastrophic worry, and depressive symptoms. Sleep disturbances predicted depressive symptoms 1-year later. Catastrophic worry partially mediated the relationship. Girls reported more sleep disturbances, depressive symptoms, and catastrophic worry relative to boys. The results, however, were similar regardless of gender. Sleep disturbances and catastrophic worry may provide school nurses, psychologists, teachers, and parents with non-gender specific early indicators of risk for depression. Several potentially important practical implications, including suggestions for intervention and prevention programs, are highlighted.     

The Role of Exposure to Self-Injury Among Peers in Predicting Later Self-Injury

While researchers are beginning to reach consensus around key psychological correlates of non-suicidal self-injury (NSSI), comparatively less work has been done investigating the role and influence of peers. Given evidence that engagement in this behavior may be susceptible to peer influence, especially during the early stages of its course, the current study prospectively explored whether knowing a friend who self-injures is associated with the onset, severity, and subsequent engagement in NSSI. The moderating roles of adverse life events, substance use and previous suicidal behavior in this relationship also were explored. Self-report data were collected from 1,973 school-based adolescents (aged 12–18 years; 72 % female) at two time points, 1 year apart. Knowing a friend who self-injured, negative life events, psychological distress and thoughts of NSSI differentiated those who self-injured from those who did not, and also predicted the onset of NSSI within the study period. Further, adverse life events and previous thoughts of NSSI moderated the relationship between exposure to NSSI in peers and engaging in NSSI at Time 2. However, the effect of having a friend who self-injures was not related to the severity of NSSI. Having a friend who self-injures appears to be a risk factor for self-injury among youth who are experiencing high levels of distress. Implications of these findings are discussed.     

Art Attacks

Far from being a matter incidental to policy, the attack on art bespeaks a more generalizable array of tactics for managing populations, while the notion that art itself bears the agency to launch an offensive, references far greater political stakes than are conventionally attributed to the esthetic domain. Policy-whether it be fiscal, domestic, military or cultural, aspires to a concrete performativity. The various government positions that authorize official pronouncements desire their words to fulfill the action they seek in the world. Even where such public pronouncements in the role of policy lack the force of law, they seek compellence by their efforts to render to world just as they say so. As arts policy makes itself increasingly manifest, its greatest ambition will be to transform policy matters from an account of what is done to us, to one that traces how artists make themselves and their worlds.     

Managing for Legitimacy: Agency Governance in Its “Deep” Constitutional Context

Recent literature on bureaucratic structure has gone further than studying discretions given to bureaucrats in policy making, and much attention is now paid to understanding how bureaucratic agencies are managed. This article proposes that the way in which executive governments manage their agencies varies according to their constitutional setting and that this relationship is driven by considerations of the executive's governing legitimacy. Inspired by Charles Tilly (1984), the authors compare patterns of agency governance in Hong Kong and Ireland, in particular, configurations of assigned decision‐making autonomies and control mechanisms. This comparison shows that in governing their agencies, the elected government of Ireland's parliamentary democracy pays more attention to input (i.e., democratic) legitimacy, while the executive government of Hong Kong's administrative state favors output (i.e., performance) legitimacy. These different forms of autonomy and control mechanism reflect different constitutional models of how political executives acquire and sustain their governing legitimacy.     

The Prosecution Service Function within the Swiss Criminal Justice System

The criminal justice system of Basel is described as a cantonal example for Switzerland. Special attention is paid to the Prosecution Service Function within this framework and its relationship to police and courts. The article not only refers to legal provisions but to the factual handling of criminal cases as well.     

Simultaneous analysis of six amphetamines and analogues in hair, blood and urine by LC-ESI-MS/MS: Application to the determination of MDMA after low Ecstasy intake

A rapid and sensitive method using LC-MS/MS triple stage quadrupole for the determination of traces of amphetamine (AP), methamphetamine (MA), 3,4-methylenedioxyamphetamine (MDA), 3,4-methylenedioxymethamphetamine (MDMA, “ecstasy”), 3,4-methylenedioxyethamphetamine (MDEA), and N-methyl-1-(3,4-methylenedioxyphenyl)-2-butanamine (MBDB) in hair, blood and urine has been developed and validated. Chromatography was carried out on an Uptisphere ODB C₁₈ 5 μm, 2.1 mm × 150 mm column (Interchim, France) with a gradient of acetonitrile and formate 2 mM pH 3.0 buffer. Urine and blood were extracted with Toxitube A^® (Varian, France). Segmented scalp hair was treated by incubation 15 min at 80 °C in NaOH 1 M before liquid–liquid extraction with hexane/ethyl acetate (2/1, v/v). The limits of quantification (LOQ) in blood and urine were at 0.1 ng/mL for all analytes. In hair, LOQ was <5 pg/mg for MA, MDMA, MDEA and MBDB, at 14.7 pg/mg for AP and 15.7 pg/mg for MDA. Calibration curves were linear in the range 0.1–50 ng/mL in blood and urine; in the range 5–500 pg/mg for MA, MDMA, MDEA and MBDB, and 20–500 pg/mg for AP and MDA. Inter-day precisions were <13% for all analytes in all matrices. Accuracy was <20% in blood and urine at 1 and 50 ng/mL and <10% in hair at 20 and 250 pg/mg. This method was applied to the determination of MDMA in a forensic case of single administration of ecstasy to a 16-year-old female without her knowledge during a party. She suffered from hyperactivity, sweating and agitation. A first sample of urine was collected a few hours after (T + 12 h) and tested positive to amphetamines by immunoassay by a clinical laboratory. Blood and urine were sampled for forensic purposes at day 8 (D + 8) and scalp hair at day 60 (D + 60). No MDMA was detected in blood, but urine and hair were tested positive, respectively at 0.42 ng/mL and at 22 pg/mg in hair only in the segment corresponding to the period of the offence, while no MDA was detectable. This method allows the detection of MDMA up to 8 days in urine after single intake.     

基础设施网络整合与跨区域治理——“哈大齐”工业走廊与松花江水污染案例分析

在全球化和信息化背景下,区域管理正在从传统的都市区(Metropolitan)管理过渡到巨型都市区(Megapolitan)或者城市走廊(City Corridor)的管理.从社会技术系统(Societal-techno System)视角,将区域管理作为一个涉众系统(Multi-actor System)考虑,研究物理系统与社会网络之间的交互作用,通过研究基础设施网络和跨区域治理关系,探索涉众系统情境下的政策制定模型.采用理论分析和案例研究相结合的方法,利用哈大齐工业走廊案例和松花江水污染案例进行了研究.结果发现,基础设施整合具有嵌入性特征;基础设施整合和专业化分工网络的形成,是跨区域治理的基础,所形成的城市网络,其核心功能体现在"分散的集中化"上,以保证有效的基础设施整合、分工网络的形成和提供高级生产者服务;在跨区域治理政策制定中,应该采用自上而下和自下而上组合的基于规则和过程的涉众情境下的政策制定过程,以实现社会、政府和市场之间的均衡.
