This study examines associations between adolescent problem behaviors and adolescent–parent disagreement in ratings of adolescent depression and anxiety symptoms. Adolescent–parent dyads (N?=?463; mean age?=?12.68 years; 48.5% female; 78.2% White and 21.8% non-White) reported on adolescent depression and anxiety using parallel scales from the Youth Self Report (Achenbach et al., J Emot Behav Disord 10:194–203, 2002) and the Child Behavior Checklist (Achenbach and Rescorla, The manual for the ASEBA school-age forms & profiles, University of Vermont, Research Center for Children, Youth, and Families, Burlington, 2001) across four waves. Generalized estimating equations were used to examine the relationship between discrepancy scores and adolescent behavioral outcomes: incidence of adolescent past-year substance use (alcohol use, binge drinking, marijuana use, and nonmedical use of controlled medications), delinquency, self-harm behavior, and aggression. Findings showed that larger adolescent–parent divergence scores of depression were associated with higher odds of marijuana use, non-medical use of controlled medications, alcohol use, binge drinking, in-school delinquency, illegal behavior, self-harm behavior, and clinically significant levels of aggressive behavior. Results further revealed that larger divergence scores on anxiety were associated with higher odds of in-school delinquency, illegal behavior, self-harm behavior, and clinically significant levels of aggressive behavior. Adolescent–parent reporting discrepancy on adolescent’s depression and anxiety symptoms may be indicative of adolescent’s social, emotional, and behavioral problems, and the disagreement may signal further need for assessment of the adolescent. 相似文献

Growing recognition of the need for better management information system (MIS) theory and practice centers around problems with identifying the value of information and information systems in organizations. This paper addresses this issue by showing that existing theory in organizational economics and industrial organization directly relates to information problems in organizations (their nature, and their effects in terms of organization structure and performance). The paper categorizes these problems and associated theories into four distinct classes and shows that MIS research and practice can be mapped to information problems of each type. Because the economic theory pertinent to specific information problems includes the nature of the organizational response to information constraints, it also provides insight into the nature of the improvement to be realized if information constraints can be overcome. These improvements can then be interpreted as the value of the associated information systems which suggests using the resultant classification scheme to map between information problems and system value. The paper shows that this methodology provides a more appropriate level of focus than either traditional normative or business value methods, especially because many improvements have structural as well as performance consequences. 相似文献

和平学是一个相对新兴和发展中的学科。从研究角度而言,和平学主要起源于欧洲国家,但大部分和平学课程却首先出现在美国。冷战后期,美国的和平学课程主要关注结构性、家庭和社会内部暴力问题。和平学的研究范围包括人际关系、组织关系和社会关系,超越了民族国家的界限,其价值基础和行动目的就是替代暴力。和平学的研究面临各种挑战,主要包括:关于和平的定义过分模糊;行政方面的支持不够;和平学还遭到政治偏见的批评。和平学有助于政治和经济政策的变化,为了促进这样的一个长时期的根本变化,需要营造一种和平的文化。 相似文献

AbstractObjective: To determine the prevalence, remission, and treatment associated with DSM-5 substance use disorders (SUDs) among young adults based on college attendance. Participants: The population-based sample included 2,057 young adults aged 19–23 in college/school and 1,213 not currently attending college/school who participated from April 2012 through June 2013. Methods: Face-to-face interviews were conducted as part of a cross-sectional national survey. Results: The prevalence of any past-year DSM-5 SUD was 39.6% among young adults in college and 44.5% among those not attending college. Past-year tobacco use disorder and multiple DSM-5 SUDs were more prevalent among those not attending college. Among those with prior-to-past-year SUDs, abstinent remission was low among college (1.0%) and noncollege (1.9%) young adults. Conclusions: Approximately two in five U.S. college students had at least one past-year DSM-5 SUD. Sustained abstinent remission from SUDs is extremely rare (1–2%) and the majority of those with SUDs do not receive treatment. 相似文献

Despite considerable quantifiable data about the circumstances of care leavers in the United Kingdom, there is less qualitative data about how these circumstances are experienced. This article is underpinned by positioning theory, with a particular focus on the unfolding personal narratives of young care leavers in relation to their mental health and wellbeing and the role of a life‐skills programme in supporting them in this respect. The research illustrates that leaving care projects, such as the one in the current study, are more focused on employment and housing issues than on addressing the mental health and wellbeing needs of young people. Our analysis of interviews with young people illustrates the ambiguity of understandings of concepts such as “mental health” and “wellbeing,” and the complexity of responses to questioning around this area. This illustrates one of the major problems in evaluating the outputs and outcomes of such projects in terms of simplistic targets, where mental health and wellbeing are not clearly defined or understood by young people themselves. The current research provides a more complex picture. More research is needed that involves in‐depth and longitudinal assessment of specific mental health needs of care leavers and how they can be addressed successfully. 相似文献

This article proceeds from a photograph. It does so to begin an investigation of the diverse sites within and beyond it, and the reflections of several enactments of nation, culture, belonging and non-belonging. The image in question depicts a group of children waving flags. It is an old photograph, possibly removed from our ‘present’, though it holds within it multi-temporal spaces into which we might enter. The aim of this article is to do just that – to enter the image, armed with all the things a researcher gathers in terms of background data, narratives and contexts, and examine the complex negotiations enacted within and beyond it. How does this group of flag-waving children impact on us today? This article explores the extent to which an understanding of a temporal enactment of nation in displacement might reflect on contemporary negotiations of citizenship, culture and representation. 相似文献
