University students are likely to experience high rates of stress, which has the potential to negatively affect academic performance and their experience of study. Research with on-campus students has found positive benefits of health-promoting behaviours such as stress reduction and academic achievement; yet no research has examined these relationships with distance education students (and in comparison with on-campus students). Distance education students are a growing cohort in Australia higher education and elsewhere. This paper aims to redress this imbalance by comparing the relationships between stress, strain and coping, academic outcomes, and health-promoting behaviours in tertiary students (on-campus and distance education students). The study involved 242 on-campus and 399 distance education students at a regional Australian university. A path model was developed comparing both cohorts, and relationships were found to be similar, indicating no significant difference. Online interventions for distance education students which could be used to enhance coping are discussed. 相似文献

Children's early language environments are related to later development. Little is known about this association in siblings of children with autism spectrum disorder (ASD), who often experience language delays or have ASD. Fifty‐nine 9‐month‐old infants at high or low familial risk for ASD contributed full‐day in‐home language recordings. High‐risk infants produced more vocalizations than low‐risk peers; conversational turns and adult words did not differ by group. Vocalization differences were driven by a subgroup of “hypervocal” infants. Despite more vocalizations overall, these infants engaged in less social babbling during a standardized clinic assessment, and they experienced fewer conversational turns relative to their rate of vocalizations. Two ways in which these individual and environmental differences may relate to subsequent development are discussed. 相似文献

Tertiary education in Papua New Guinea (PNG) is in a critical state, as the sector struggles to address increased demand for student places with severely curtailed capacity. Recent thinking about improving public services in PNG has emphasized “whole of sector” or collaborative governance. Such an approach in tertiary education has the potential to improve the sector’s outcomes within its existing resource constraints. This exploratory paper examines the challenges involved in applying a deliberate collaborative governance approach to tertiary education in PNG. In particular, two theoretical models of collaborative governance are employed to gain insight into possible issues through the consideration of four main criteria: power, incentives, history, and leadership. The paper shows that the challenges to introducing collaborative governance to PNG tertiary education are substantive, and that any effective effort will require committed leadership and a carefully measured strategy that acknowledges the country’s particular circumstances. 相似文献

This study provides a cost–benefit analysis of expanding access to universal preschool education, focusing on a Spanish reform that lowered the age of eligibility for publicly provided universal preschool from age 4 to age 3. Benefits in terms of child development and maternal employment are estimated using evidence on the causal effects of this reform. In the baseline estimation the benefit–cost ratio is over 4, indicating sizeable net societal benefits of the preschool investment. The results show that the child development effects are the major determinant of the cost–benefit ratio; the employment gains for parents appear to play a relatively minor role. Overall, the cost–benefit analysis provides support for investing in high-quality preschool education. 相似文献

In threatening environments, the short (S) allele of 5-HTTLPR is proposed to augment risk for depression. However, it is unknown whether 5-HTTLPR variation increases risk for depression in environments of deprivation, lacking positive or nurturant features. Two independent longitudinal studies (n = 681 and 176, respectively) examined whether 5-HTTLPR moderated associations between low levels of positive parenting at 11–13 years and subsequent depression at 17–19 years. In both studies only LL homozygous adolescents were at greater risk for depression with decreasing levels of positive parenting. Thus, while the S allele has previously been identified as a susceptible genotype, these findings suggest that the L allele may also confer sensitivity to depression in the face of specific environmental challenges. 相似文献

This exploratory qualitative study of 117 teachers explores how educators engage with Pinterest, an online social networking site, specifically asking: (1) What similarities and differences exist in how elementary-level preservice and elementary-level in-service teachers engage with Pinterest? (2) What similarities and differences exist in how secondary-level in-service teachers and elementary-level in-service teachers engage with Pinterest? Findings indicate teachers at all levels tend to use Pinterest to search for educational resources and adapt resources to suit their classroom needs. Preservice teachers identify a more complex interaction with Pinterest than in-service teachers when determining quality resources. Findings indicate a need for future research into teacher education practices and the complex interactions preservice teachers engage in with Pinterest resources. 相似文献
