Caffeine is the most widely used psychoactive substance in the world and currently the only one legally available to children and adolescents. The sale and use of caffeinated beverages has increased markedly among adolescents during the last decade. However, research on caffeine use and behaviors among adolescents is scarce. We investigate the relationship between adolescent caffeine use and self-reported violent behaviors and conduct disorders in a population-based cross-sectional sample of 3,747 10th grade students (15–16 years of age, 50.2 % girls) who were enrolled in the Icelandic national education system during February 2012. Through a series of multiple regression models, while controlling for background factors, Attention Deficit Hyperactivity Disorder symptoms and current medication and peer delinquency, and including measures on substance use, our findings show robust additive explanatory power of caffeine for both violent behaviors and conduct disorders. In addition, the association of caffeine to the outcomes is significantly stronger for girls than boys for both violent behaviors and conduct disorders. Future studies are needed to examine to what extent, if at all, these relationships are causal. Indication of causal connections between caffeine consumption and negative outcomes such as those reported here would call into question the acceptability of current policies concerning the availability of caffeine to adolescents and the targeting of adolescence in the marketing of caffeine products. 相似文献

The present inquiry focuses upon recent levels and trends of public support and nonsupport of the U.S. Congress. The data are drawn from statewide surveys of Wisconsin adults in 1970–1978 and from such sources as CPS/NES, Gallup, and Harris. Measurement focuses upon four major types of public support for Congress—pure specific support (performance), pure diffuse support (including general confidence in the institution, sense of personal efficacy in relation to Congress, desire for institutional reform or maintenance and the amount of power preferred for Congress relative to other branches), and two mixed types of support, long-term performance assessments and confidence in congressional incumbents. With few exceptions, Congress has suffered a general erosion of public support over the past decade on most indicators.An earlier, longer version of this paper was presented at the XIth World Congress of the International Political Science Association, Moscow, USSR, August 1979. 相似文献

Brian Jack 《European Law Journal》2013,19(3):404-421
Article 260(2) TFEU (ex 228(2) EC) enables the European Court of Justice to enforce compliance with its judgements. This article analyses its use in doing so and questions whether it could be applied more effectively. It commences by highlighting the principally economic and environmental context of the case‐law, and by examining the initiatives taken to tackle delays in bringing these cases before the Court. The article then critically evaluates the effectiveness of the financial sanctions available to the Court. In doing so, it aims to fill a gap in present research by looking beyond the procedural measures through which the Court and the Commission operate to examine the practical impact of Article 260(2) itself. 相似文献

There is a serious issue within the forensic science community, which even extends outside of the field. The role of the scientist in the investigation of crime has been increasingly confined to the laboratory, which has been accompanied by the conflation of the terms forensic science and criminalistics. This unfortunate situation has been festering for years. To make matters worse, the era of the proactive, problem-defining, criminalist (generalist) is waning, and possibly over. Present-day “criminalists” are treated as little more than reactive, protocol-constrained, laboratory technicians, with few, if any, consequential crime scene roles. In most cases, these “criminalists” merely respond to routine requests from prosecutors and police. The absence of science at the front end of forensic investigations, i.e., the scene, has resulted in biased, ineffective, inefficient, and/or erroneous outcomes with immediate and long-term societal impacts. To disentangle this imbroglio, we propose the use of another term, traceology, which has seen limited use worldwide except in the field of archaeology. With respect to criminalistics, this term has been previously proposed by Margot (20–21). Traceology is an historical science, dealing with the examination, analysis, and scientific interpretation of event traces (signs or remnants) of earlier activities. In this commentary, we define and redefine familiar, but ambiguous, terms and concepts with the hope of recapturing the essence of criminalistics (32), which we suggest is best termed traceology. 相似文献

In the United States, there is an ongoing debate about requiring health care professionals to report intimate partner violence (IPV) to law enforcement agencies. A comprehensive examination of the perspectives of those required to report abuse is critical, as their roles as mandated reporters often pose legal, practical, moral, and ethical questions. Even so, the perspective of health care professionals who are required to report is often overlooked and research is scarce on mandated reporters who work outside of clinical settings, such as nurses who engage in home visitation with clients. The purpose of this study was to examine nurse home visitors' perspectives regarding the mandatory reporting of IPV, specifically focusing on their attitudes toward reporting, perceived awareness of reporting requirements, and intended reporting behaviors. A web-based survey was administered to nurses in the Nurse-Family Partnership home visitation program across the United States. A total of 532 completed surveys were returned (response rate = 49%). In terms of support for reporting IPV, 40% of nurses indicated that they should "always" be required to report. Almost half of the sample indicated that they would report a case of IPV, yet less than one-third of participants were aware of a legal mandate. Attitudes and support toward reporting as well as the perception of a reporting requirement significantly predicted intention to report. Furthermore, 29% of participants did not know if they were required to report IPV perpetrated against their clients. Comprehensive information about mandatory reporting duties is needed for health care professionals in home visitation settings. The findings of the current study highlight the need to reduce variation among practitioners and establish consistent program practices that are grounded in the program's principals, supported by existing research, and compliant with existing state policies. 相似文献

Rt Hon Jack Straw MP 《British Journal of Middle Eastern Studies》2015,42(4):375-383
Former Foreign Secretary Jack Straw draws on his experience and Britain's colonial legacy to argue that while the United Kingdom needs to recognise the effects of past policy and how it is perceived in the Middle East, the UK should not be a prisoner of its legacies from the past. In this annual address to the British Society for Middle Eastern Studies (BRISMES) he argues that knowledge should be used to create in-depth understanding that in turn should be built on to create more enduring foreign policy goals. He puts forward a coherent case for a more positive and comprehensive relationship with Iran and Turkey as potential allies in building more stable and yet also more democratic and accountable governments throughout the Middle East. Jack Straw argues that the UK is better placed than many to learn from past mistakes and create more robust strategic goals for the future. 相似文献
