The components of family policy education

The study of family policy in the United States began relatively recently. The academic community increasingly has shown interest in this new policy arena. Much of the conceptual writing on family policy emerged from disciplines such as family studies, social work, political science, economics, and sociology. These academic units have recently modified their course curricula to include more family policy content. These family policy education efforts are discussed in this article. Specific suggestions are made concerning the development and content of family policy education, broader educational training for those who want to pursue a career in family policy, and future goals and directions for family policy education.

Her research interests are in the family and health policy arenas, with particular focus on ethnically diverse populations. Her most recent research is on homeless children and mothers. She received her Ph.D. in Family Social Science from the University of Minnesota. Her teaching and research interests are workplace and family issues and family policy and impact analysis.     

A class of residuals for outlier identification in zero adjusted regression models

Zero adjusted regression models are used to fit variables that are discrete at zero and continuous at some interval of the positive real numbers. Diagnostic analysis in these models is usually performed using the randomized quantile residual, which is useful for checking the overall adequacy of a zero adjusted regression model. However, it may fail to identify some outliers. In this work, we introduce a class of residuals for outlier identification in zero adjusted regression models. Monte Carlo simulation studies and two applications suggest that one of the residuals of the class introduced here has good properties and detects outliers that are not identified by the randomized quantile residual.     

博彩业迅速发展后的澳门青少年价值观探析

澳门博彩业近年高速发展,对于社会的各个层面都产生深远的影响。为了探讨博彩业发展对澳门年青新一代的价值观的影响,本研究以问卷调查为主,结合访谈和文献研究进行分析。结果我们发现博彩业的发展为澳门青少年带来了更多的竞争意识,令他们承受压力的能力增强,自我增值的意识也较强。但是在博彩业发展的同时,部分澳门青少年视博彩行业只是赚钱的途径,"个人成就"等人生目标在现今特定的社会情况下变得迷惘,而高度的商业化令本来已不深的人文根基变得更加薄弱。总体而言,近年博彩业的发展已令澳门青少年的人生价值观、社会价值观和择业价值观等受到了冲击。     

Reliability and validity of responses to submaximal all-extremity semirecumbent exercise in older adults

Although popular in clinical settings, little is known about the utility of all-extremity semirecumbent exercise machines for research. Twenty-one community-dwelling older adults performed two exercise trials (three 4-min stages at increasing workloads) to evaluate the reliability and validity of exercise responses to submaximal all-extremity semirecumbent exercise (BioStep). Exercise responses were measured directly (Cosmed K4b2) and indirectly through software on the BioStep. Test-retest reliability (ICC2,1) was moderate to high across all three stages for directly measured METs (.92, .87, and .88) and HR (.91, .83, and .86). Concurrent criterion validity between the K4b2 and BioStep MET values was moderate to very good across the three stages on both Day 1 (r = .86, .71, and .83) and Day 2 (r = .73, .87, and .72). All-extremity semirecumbent submaximal exercise elicited reliable and valid responses in our sample of older adults and thus can be considered a viable exercise mode.     

Übungsformen in Coaching-Weiterbildungen – Ergebnisse einer Online-Befragung

Coaching training research has up to now, from an evaluative perspective, mainly considered the participants’ satisfaction and competence development. The present study, however, focuses on the conceptualization of trainings, specifically the practical parts and the exercise forms which are used in coaching trainings. In the course of an online-survey, data from 209 coaching trainers could be obtained.     

Predicted risk perception and risk-taking behavior: The case of impaired driving

Research suggests an association between risk perception and risk-taking behavior in a variety of contexts. There is empirical evidence that perceived risk is generally biased and that perception of risk influences behavior. Perception of risk can be endogenous. It is therefore more appropriate to instrument risk perception. This article studies the perception of the risks associated with impaired driving and the relation between predicted risk perception and driving behavior. We survey a sample of license-holders, half of whom are drivers with a past conviction for impaired driving, the other half or control group without such conviction. Predicted perceptual biases are shown to influence actual driving behavior.

What are they hearing? The impact of perceptions of parental communication on youth

Work and family domains mutually influence one another in positive and negative ways. A fair amount of evidence supports the spillover effects between these two domains. In addition, research on crossover supports how one spouse may be influenced by another spouse's spillover. Much less evidence exists about how it affects other family members, especially children. This qualitative interpretive study explores emergent themes related to youth perceptions of how their parents' work–family spillover impacts them. Using crossover as a guiding framework, youth (N = 55) participated in a semistructured interview about their perceptions of their parents' communication regarding blending work and family and how it impacts those youth participants. The analysis of the transcribed interviews revealed several emergent themes related to youth awareness of and the impact of work–family integration issues as well as youth perceptions about their own futures. The results suggest the ways in which socialization occurs through a socially constructed view of work and family and the impact those constructions have on vocational decisions.     

Interruption and Forgetting in Knowledge‐Intensive Service Environments

An increasing barrier to productivity in knowledge‐intensive work environments is interruptions. Interruptions stop the current job and can induce forgetting in the worker. The induced forgetting can cause re‐work; to complete the interrupted job, additional effort and time is required to return to the same level of job‐specific knowledge the worker had attained prior to the interruption. This research employs primary observational and process data gathered from a hospital radiology department as inputs into a discrete‐event simulation model to estimate the effect of interruptions, forgetting, and re‐work. To help mitigate the effects of interruption‐induced re‐work, we introduce and test the operational policy of sequestering, where some service resources are protected from interruptions. We find that sequestering can improve the overall productivity and cost performance of the system under certain circumstances. We conclude that research examining knowledge‐intensive operations should explicitly consider interruptions and the forgetting rate of the system's human workers or models will overestimate the system's productivity and underestimate its costs.     

Use of jump process to model mobility in massive multiplayer on-line games

This paper proposes a methodology to model the mobility of characters in Massively Multiplayer On-line (MMO) Games. We propose to model the mobility of characters in the map of an MMO game as a jump process using two approaches to model the times spent in the states of the process: parametric and non-parametric. Furthermore, a simulator for the mobility is presented. We analyze geographic position data of the characters in the map of the game World of Warcraft and compare the observed and simulated data. The proposed methodology and the simulator can be used to optimize computing load allocation of servers, which is extremely important for game performance, service quality and cost.
