The purpose of this study was to expand the knowledge base on parental knowledge by assessing a developmental trajectory and factors that might predict parental knowledge among Korean adolescents. To address this purpose, the current study assessed changes in parental knowledge during the transition to adolescence using hierarchical linear modeling (HLM). In addition, parental warmth and adolescent disclosure were considered as time-variant predictors of knowledge. The data from Korea Youth Panel Survey (KYPS) of Grade 4 students who were followed for five years was analyzed. The results indicated that there was a significant average increase followed by a slight decrease in parental knowledge over time; that is, the data followed a quadratic trend. Controlling for gender and family structure, the study found that parental warmth and adolescent disclosure had significant effects on parental knowledge over time. The study's results suggest that parental warmth and adolescent disclosure are important elements to be emphasized in prevention and intervention programs that promote parental knowledge. 相似文献

Recent studies have confirmed a high prevalence of youth with diagnosable mental health disorders within the juvenile justice system, as well as the vulnerability of youth in the mental health system who enter the juvenile justice system. This high prevalence of dual system involvement has spawned challenges of collaboration between the mental health and juvenile justice systems to provide needed services to youth and their families. Seventy-two in-depth interviews were conducted with 18 youth and their parents/guardians, mental health professionals from five different community mental health centers, and juvenile justice professionals in urban and rural communities in a Midwest state in the United States. Professionals, youth and parents identified several important factors that facilitated collaboration, as well as a myriad of barriers that needed to be overcome. Findings suggest ways to improve partnerships between the two systems and the development of supportive policies and procedures. 相似文献

ABSTRACTEmotion dysregulation has been identified as a transdiagnostic mechanism underlying social phobia and depression; however, there is much to learn about how emotion dysregulation leads to these specific outcomes. Thus, this study examined the relationship pattern between anger dysregulation and depression and how it is mediated by social phobia. Anger dysregulation was examined specifically considering anger as a significant emotional feature of both social phobia and depression. The mediation hypothesis within this study was empirically established. The data was drawn from the Collaborative Psychiatric Epidemiology Surveys (2001–2003), in which 2,827 participants met DSM-IV criteria for lifetime major depressive disorder (14.3%), and 1,905 participants met criteria for DSM-IV lifetime social anxiety disorder (9.6%). Among participants, 4,250 (21.5%) reported that they perceived their anger as out of control and either broke items or hit (or tried to hit) others. The mediation hypothesis was tested with logistic regression models. Anger dysregulation was significantly related to social phobia and depression. A significant indirect effect of social phobia was detected through bootstrap analysis, supporting the partial mediation hypothesis. This study represents the first attempt to examine the mediating role of social phobia in the relationship between anger dysregulation and depression. The findings of this study suggest that anger dysregulation may be a transdiagnostic factor across social phobia and depression. 相似文献

In the current global business environment, it is very important to know how to allocate products from the producer to buyers (or distributors). If products are not appropriately distributed due to absence of an effective allocation policy, the producer and buyers cannot expect to increase customer satisfaction and financial profit. Sometimes some buyers can order more than the actual demand due to inappropriately forecasting customer orders. This is the big obstacle to the effective allocation of products. If the producer can become aware of buyers’ actual demands, it is possible to realise high-level order fulfilment through the effective allocation of products. In this study, new allocation policies are proposed considering buyers’ demands. The back propagation algorithm, one of the learning algorithms in neural network theory, is used to recognise actual demands from the previous buyers’ orders. After excluding surplus demands included in buyers’ demands, products are allocated to buyers according to one of the existing allocation policies depending on the company's decision. In the numerical examples, new allocation policies reducing buyers’ surplus demands outperform previous allocation policies with respect to average amount of backorder. 相似文献

We consider estimation in the class of first order conditional linear autoregressive models with discrete support that are
routinely used to model time series of counts. Various groups of estimators proposed in the literature are discussed: moment-based
estimators; regression-based estimators; and likelihood-based estimators. Some of these have been used previously and others
not. In particular, we address the performance of new types of generalized method of moments estimators and propose an exact
maximum likelihood procedure valid for a Poisson marginal model using backcasting. The small sample properties of all estimators
are comprehensively analyzed using simulation. Three situations are considered using data generated with: a fixed autoregressive
parameter and equidispersed Poisson innovations; negative binomial innovations; and, additionally, a random autoregressive
coefficient. The first set of experiments indicates that bias correction methods, not hitherto used in this context to our
knowledge, are some-times needed and that likelihood-based estimators, as might be expected, perform well. The second two
scenarios are representative of overdispersion. Methods designed specifically for the Poisson context now perform uniformly
badly, but simple, bias-corrected, Yule-Walker and least squares estimators perform well in all cases. 相似文献

Restorative justice conferences including Victim Offender Mediation (VOM) are rapidly increasing. Due to a lack of participants’
accounts on their experiences, gaining knowledge on how restorative justice works from their perspective is critical, especially
to further development of justice policy and practice. In this exploratory qualitative study we interviewed 37 participants
in a VOM operating in a mid-sized Midwestern city in the United States. In this article, we examine some youths’ experiences
in their VOM to deepen our understanding of how and why restorative discourses work. Findings suggest that meeting their victims
through VOM helped the youths realize the extent of the consequences of their actions by being able to personalize their victims
and their victimized experiences. In conclusion we highlight the importance of appreciating the unseen effects of the crimes.
Lastly, we make some recommendations for practitioners to assist their developing better programs in dealing with youths in
restorative justice contexts. 相似文献

This paper examines gender differences in life with and without six major diseases, including both mortal and morbid conditions. Disease prevalence and health behavior data are from the 1993-1995 National Health Interview Surveys for the United States. Vital registration data are the source of mortality rates used in computing life expectancy. The Sullivan method is used to estimate life lived with and without disease and risky behavior for men and women at various ages. Women live more years with each of the diseases examined, and, for arthritis, the extended years with disease are greatest. Women also live more years than men free of each of these diseases with the exception of arthritis. Gender differences in life without two health-risk behaviors are also discussed. Men spend more years of their lives overweight and have fewer years during which they see a doctor. 相似文献

ABSTRACTHow disinformation campaigns operate and how they fit into the broader social communication environment – which has been described as a ‘disinformation order’ [Bennett & Livingston, (2018). The disinformation order: Disruptive communication and the decline of democratic institutions. European Journal of Communication, 33(2), 122–139] – represent critical, ongoing questions for political communication. We offer a thorough analysis of a highly successful disinformation account run by Russia’s Internet Research Agency: the so-called ‘Jenna Abrams’ account. We analyze Abrams’ tweets and other content such as blogposts with qualitative discourse analysis, assisted by quantitative content analysis and metadata analysis. This yields an in-depth understanding of how the IRA team behind the Abrams account presented this persona across multiple platforms and over time. Especially, we describe the techniques used to perform personal authenticity and cultural competence. The performance of personal authenticity was central to her persona building as a likeable American woman, whereas the performance of cultural competence enabled her to infiltrate American conservative communities with resonant messages. Implications for understanding disinformation processes, and how some aspects of the hybrid media system are especially vulnerable to hijacking by bad actors are discussed. 相似文献
