This study examined sensitive parenting as a protective factor in relations between interparental violence (IPV) and children's coping and psychological adjustment. Using a multimethod approach, a high‐risk sample of 201 two‐year‐olds and their mothers participated in three annual waves of data collection. Moderator analyses revealed that sensitive parenting buffered the risk posed by IPV on children's changes in externalizing and prosocial development over a 2‐year period. Tests of mediated moderation further indicated that sensitive parenting protected children from the vulnerability of growing up in a violent home through its association with lower levels of children's angry reactivity to interparental conflict. Results highlight the significance of identifying the mechanisms that mediate protective factors in models of family adversity.  相似文献

Education policy in England has explicitly aimed to remodel state schools in the image of independent, private, schools. However, the body of research evidence on the operation of private schools is very small. Critics have frequently argued that, in contrast to state schools, private schools use resources efficiently because their autonomy gives them freedom to make efficient choices in response to market pressures. We investigated the resource allocation decisions of income private schools using data from their financial accounts. We report the associations of private school spending and performance and teacher and non‐teacher numbers, teacher salaries and regional earnings. Schools with higher fees had more teachers and non‐teachers per pupil, but similar average staff wages to schools with lower income. Yet we found little evidence that achievement was associated with resource use in English private schools. That is, we found no evidence to support the view that financial autonomy enabled flexibility in using resources to promote higher achievement.  相似文献

ABSTRACT

Little is known regarding the influence of asthma and exercise, and their interaction, on heart rate variability (HRV) in adolescents.

Thirty-one adolescents with asthma (13.7±0.9 years; 21.9±3.9 kg·m?2; 19 boys, 12 girls) and thirty-three healthy adolescents (13.8±0.9 years; 20.3±3.2 kg·m?2; 16 boys, 17 girls) completed an incremental ramp test and three heavy-intensity constant-work-rate cycle tests. Thirteen adolescents (7 boys, 6 girls; 6 asthma, 7 control) completed six-months high-intensity interval training (HIIT) and were compared to age- and sex-matched controls. Standard time-domain, frequency-domain and non-linear indices of HRV were derived at baseline, three- and six-months.

Asthma did not influence HRV at baseline or following HIIT. Total power, low frequency and normalised low frequency power, and sympathovagal balance increased at three-months in HIIT, subsequently declining towards baseline at six-months. Normalised high frequency power was reduced at three-months in both groups, which was sustained at six-months. No effects of HIIT were observed in the time-domain nor in the non-linear indices.

HRV was not influenced by asthma, potentially because such derangements are a function of disease progression, severity or duration. HIIT may be associated with a short-term shift towards greater sympathetic predominance during exercise, perhaps caused by physiological overload and fatigue.  相似文献

Attending to instruction is a critical behavior for academic success. Many elementary school teachers, however, identify disruptive and inattentive classroom behaviors as key barriers to students' successful educational performance. This study examined the impact of two class‐wide positive behavior support programs. The Mystery Motivator and Get 'Em On Task interventions were implemented in an alternating treatments design with fifth grade participants to decrease off‐task behaviors. Results indicated that both interventions effectively decreased off‐task behavior at the class‐wide level. Implications and suggestions for future research on evidence‐based behavioral interventions are discussed. © 2011 Wiley Periodicals, Inc.  相似文献

Advancing the long‐term prospective study of explanations for the effects of marital conflict on children’s functioning, relations were examined between interparental conflict in kindergarten, children’s emotional insecurity in the early school years, and subsequent adolescent internalizing and externalizing problems. Based on a community sample of 235 mothers, fathers, and children (Ms = 6.00, 8.02, 12.62 years), and multimethod and multireporter assessments, structural equation model tests provided support for emotional insecurity in early childhood as an intervening process related to adolescent internalizing and externalizing problems, even with stringent autoregressive controls over prior levels of functioning for both mediating and outcome variables. Discussion considers implications for understanding pathways between interparental conflict, emotional insecurity, and adjustment in childhood and adolescence.  相似文献

Based on analysis of an administrative dataset, which includes granular detail on 800,000 English students over a 10-year period, this article identifies an urban ‘escalator’ effect in entry to elite universities, with disadvantaged youth in the urban centres of England having higher rates of entry than similarly disadvantaged youth located rurally. Using multilevel modelling, as well as Geographic Information System (GIS) methods, the analyses show that while place in itself is not a major contributory factor in entry to elite universities overall, there is a distinct urban–rural patterning to progression. When raw progression rates by area alone are observed, rural areas typically have higher progression rates to elite universities. However, when the full range of individual differences are accounted for, including attainment, socio-economic status, ethnicity and accessibility to elite universities, the converse is true—localities within and surrounding major urban centres are those with the highest progression rates. A ‘vortex of influences’ is likely to favour urban disadvantaged youth, including the geography of social class and ethnic identities, a legacy of concerted policy interventions within urban areas, as well as the proliferation of widening participation activity in urban centres.  相似文献

This paper examines BSc Physiotherapy students’ experiences of developing their neurological observational and analytical skills using a blend of traditional classroom activities and computer‐based materials at the University of Birmingham. New teaching and learning resources were developed and supported in the School of Health Sciences using Web Course Tools combined with a wide range of video clips of patients with neurological disorders on CD‐ROM. These resources provided students with the opportunity to observe “real patients” prior to clinical placements, thus bridging the gap between their theoretical understanding of these disorders and their practical experience of evaluating abnormal movement in the clinical setting. This paper considers how this blended approach to learning enhanced students’ experiences of developing their neurological skills and of preparing for their clinical placements. This paper also discusses the lessons that have been gained from students’ experiences to provide future or similar projects with the opportunity to learn from these experiences.  相似文献

Agency as a Form of Discursive Practice. A Classroom Scene Observed   总被引:1,自引:0,他引:1  
In this paper an analysis of the concept of agency is undertaken. The traditional or agonistic definition of agency which assumes that to be a person is to have agency is rejected in favour of a definition that shows the way in which agency may be discursively constructed as a positioning made available to some but not to others. This analysis is then applied to an episode in a primary school classroom to see whether the discursive practices in that classroom can be said to position the students as agentic. The particular classroom was chosen on the basis of the teacher's explicit wish that his students be agentic, but what the analysis shows is the extreme complexity involved in actually carrying this off, given all of the contradictory beliefs and practices that militate against children actually being agentic.  相似文献

This paper assesses the value that can be put on the mathematical Standard Assessment Task (SAT) score as an indicator of how children are doing compared to others. The results of a study of a sample of 171 Year 2 children from five randomly selected primary schools within one Local Education Authority (LEA) are presented. Pupils’ scores on Mathematics 7, a standardised mathematics test for 7 year‐olds are compared to the mathematics SAT score elicited by them in the previous half‐term. Results show that children with the same Mathematics 7 score may be designated Level 1, 2 or 3 on the mathematics SAT. Conclusions, based on such a small study, are tentative. There is a need to be aware that finding out how a child is doing may be more complicated than simply looking at the SAT results. It may be hypothesised that the 10 point assessment scale is too crude a summative device to measure children's mathematical standards accurately.  相似文献

This paper assesses the value that can be put on the reading (National Curriculum En 2) Standard Assessment Task scores as indicators of what children are achieving in reading and whether reading standards are rising. The results of a cross-sectional study of a sample of all the Year 2 children (171 in 1991; 171 in 1992) from five randomly selected primary schools within one Local Education Authority (LEA) are presented. Pupils’ scores on The Primary Reading Test (PRT) (France, 1981) and the reading Standard Assessment Task score elicited by them in the previous half term are compared. Results show an improvement in the attainment level of children in 1992 compared to those in 1991 on Standard Assessment Tasks with a higher percentage achieving Level 3 and fewer on Level 1. However, examination of the means for each year group indicates that the mean PRT score for each Standard Assessment Task level is significantly lower in 1992 than 1991. Conclusions, based on such a small study, are tentative. However, it would seem that there is a need to view apparently rising standards, as measured solely by the Standard Assessment Task results, with a degree of caution.  相似文献
