An intervention for relational and physical aggression in early childhood: A preliminary study

A preventive intervention for reducing physical and relational aggression, peer victimization, and increasing prosocial behavior was developed for use in early childhood classrooms. Nine classrooms were randomly assigned to be intervention rooms (N = 202 children) and nine classrooms were control rooms (N = 201 children). Classroom was the unit of analysis and both observations and teacher-reports were obtained at pre and post-test. Focus groups were used to develop the initial program. The 6-week program consisted of developmentally appropriate puppet shows, active participatory sessions, passive concept activities and in vivo reinforcement periods. Preliminary findings suggest that the “Early Childhood Friendship Project” tended to reduce physical and relational aggression, as well as physical and relational victimization and tended to increase prosocial behavior more for intervention than control classrooms. Teachers and interventionists provided positive evaluations of the program and there is evidence for appropriate program implementation.  相似文献

Hand/wrist disorders among sign language communicators     

Smith SM  Kress TA  Hart WM 《American annals of the deaf》2000,145(1):22-25

The study assessed the frequency of self-reported hand/wrist problems among sign language communicators, including interpreters, deaf or hard-of-hearing individuals, and educators. Comparisons were also made between sign language communicators and the general population regarding the frequency of medically diagnosed carpal tunnel syndrome. A survey was mailed to attendees of a national conference that focused on the quality of postsecondary educational opportunities for students with hearing deficits. Fifty-nine percent of 184 respondents reported experiencing hand/wrist problems. Twenty-six percent reported experiencing hand/wrist problems severe enough to limit the ability to work, and 18% reported a medical diagnosis of wrist tendinitis, carpal tunnel syndrome, or both. The frequency of self-reported, medically diagnosed carpal tunnel syndrome for the surveyed sign language communicators was five times the rate experienced by working Americans between ages 18 and 60 years (Tanaka, Wild, Seigman, Halperin, Behrens, & Putz-Anderson, 1995). The study supports increased emphasis on and availability of hand/wrist disorder risk reduction programs for sign language users.  相似文献   

Child care and family processes: Bi-directional relations between child care quality,home environments,and maternal depression     

Emma R. Hart  Deborah Lowe Vandell  Anamarie A. Whitaker  Tyler W. Watts 《Child development》2023,94(1):e1-e17

The current study examined whether within-family changes in child care quality and quantity predicted subsequent changes in home environment quality and maternal depression across early childhood (6 to 54 months of age). Data were drawn from the NICHD Study of Early Child Care and Youth Development (n = 1239; 77% White; 48% female; data collection from 1991 to 1996), and were analyzed using Random Intercept Cross-Lagged Panel Models. Within-family increases in child care quality predicted modest increases in home environment quality (β = .13–.17). These effects were most robust from child age 6 to 15 months. Increases in child care quality produced small, statistically non-significant, reductions in depression. Time-specific increases in child care quantity were not consistently predictive of either outcome.  相似文献

A factorial analysis of timed and untimed measures of mathematics and reading abilities in school aged twins     

Sara A. Hart  Stephen A. Petrill  Lee A. Thompson 《Learning and individual differences》2010,20(2):63-69

The present study examined the phenotypic and genetic relationship between fluency and non-fluency-based measures of reading and mathematics performance. Participants were drawn from the Western Reserve Reading and Math Project, an ongoing longitudinal twin project of same-sex MZ and DZ twins from Ohio. The present analyses are based on tester-administered measures available from 228 twin pairs (age M = 9.86 years). Measurement models suggested that four factors represent the data, namely Decoding, Fluency, Comprehension, and Math. Subsequent quantitative genetic analyses of these latent factors suggested that a single genetic factor accounted for the covariance among these four latent factors. However, there were also unique genetic effects on Fluency and Math, independent from the common genetic factor. Thus, although there is a significant genetic overlap among different reading and math skills, there may be independent genetic sources of variation related to measures of decoding fluency and mathematics.  相似文献   

Training Older Workers: Implications for HRD/HPT Professionals     

Jeff M. Allen  Marcy Hart 《Performance Improvement Quarterly》1998,11(4):91-102

In corporations across America, a race is on to find new ways to maximize human capital. An emphasis on lifelong learning will be vital for the success of our future workforce. As demographic shifts occur, the “older worker” will emerge as a primary target for this human development effort. This article explores the implications of this demographic shift for the human resource development and human performance technology (HRD/HPT) professional and recommends strategies for meeting this business need. First, we discuss the realities of this demographic shift and compare our current workforce demographics to those of the future. Next, we examine the common myths about the “older worker,” as well as what current research reports about this special population. Finally, we examine the impact of this trend on our profession. We discuss strategies for modifying the workplace environment, reassessing workforce motivational strategies, and altering training practices in order to serve this older worker population. In conclusion, we look at the implications for the future in HRD/HPT research.  相似文献   

An Overview of Significant Influences and Formative Experiences on the Development of Adults’ Environmental Awareness in Nine Countries     

Joy A. Palmer  Jennifer Suggate  Barbara Bajd  Paul Hart K.P.  Roger K.P. Ho  J.K.W. Ofwono‐Orecho 《Environmental Education Research》1998,4(4):445-464

This article, like the preceding one in this special issue of the journal, examines the relative importance of various categories of influence and formative life experiences on the development of environmental educators’ knowledge of and concern for the environment. It provides an overview of data deriving from nine countries (Australia, Canada, Greece, Hong Kong, Slovenia, South Africa, Sri Lanka, Uganda, UK) and highlights global similarities and differences.  相似文献
