网络课堂中非生理性别与生理性别对人际冲突的影响(英文)

本研究探讨了性别对网络课堂中学生间冲突程度的影响。研究者首先检查了文化和冲突间的关系,并且对性别和冲突间的关联做了文献分析,接着具体探索了生理和非生理性别（sex,gender）、网络学习经验（所上网络课程的多少）,和冲突在网络学习环境中的关联。虽然研究男女性别和冲突的文章有很多,但研究更深一步探求抽象性别（即gender,非生理性别）对冲突程度和态度的影响。研究中采用了专门研究性别和冲突的问卷调查工具。     

Investigating the enactment of social presence in blended adult education

ABSTRACT

Background

While open-cohort blended education programmes allow for accessible and flexible study trajectories, they may present social challenges to learners. Social presence is a possible a way of enhancing adult learners’ success. It can lead to an increased perception of community, which may result in lower rates of dropping out.     

Cortisol in Neonatal Mother's Milk Predicts Later Infant Social and Cognitive Functioning in Rhesus Monkeys

Milk provides not only the building blocks for somatic development but also the hormonal signals that contribute to the biopsychological organization of the infant. Among mammals, glucocorticoids (GCs) in mother's milk have been associated with infant temperament. This study extended prior work to investigate rhesus monkey (Macaca mulatta) mother–infant dyads (N = 34) from birth through 8 months postpartum. Regression analysis revealed that cortisol concentrations in milk during the neonatal period predicted impulsivity on a cognitive task, but not global social behaviors, months later. During this time period, sex‐differentiated social behavior emerged. For female infants, milk cortisol concentrations predicted total frequency of play. Collectively, these findings support and extend the “lactational programming” hypothesis on the impact of maternal‐origin hormones ingested via milk.     

Amazing race: Finding and correctly citing credible sources

Courses: Public Speaking and courses familiarizing students with finding/citing sources.

Objective(s): After completing the activity, students will understand how to find and cite information in print, online, and personal communication formats.     

Schooling and local environmental knowledge: Do they complement or substitute each other?

Schooling and the knowledge acquired at school have been considered both a cause of loss of indigenous knowledge (because it opens pathways to the non-indigenous world and worldviews) and a potential remedy to its demise (if educational curricula is aligned with indigenous realities by giving instruction in local languages and incorporating local knowledge in school content). We test the association between academic and local environmental knowledge using data from a society of forager-horticulturalists in the Bolivian Amazon who were exposed to a partially contextualized school curriculum. We found that although schooling and academic knowledge bear a negative association with local knowledge the magnitude is low, probably because schooling was partially contextualized. Contextualized learning might help avoid that the provision of universal education comes at the cost of humanity's cultural diversity.     

Dimensions of coping and anxiety symptoms in a community sample of young children

Coping style plays an important role in children’s wellbeing. This paper describes the patterns of associations between children’s self-reported coping styles and symptoms of anxiety in order to determine whether particular dimensions are associated with better adjustment. Participants were 2566 children (1268 girls, 1298 boys) aged 7–11 years attending 15 schools in the South East of England. Results showed that aspects of coping were differentially associated with children’s self-reported anxiety. Patterns of association also varied by age and gender. Dimensions of coping were shown to form distinct adaptive and maladaptive coping styles which were also differentially associated with anxiety. Analysis of these styles indicated that it is the absence of maladaptive coping strategies, rather than the presence of adaptive strategies, that is significant in emotional wellbeing. These findings suggest that interventions designed to reduce or extinguish maladaptive coping styles may be of particular benefit in facilitating emotional wellbeing.     

A comparison of accelerometry analysis methods for physical activity in older adult women and associations with health outcomes over time

ABSTRACT

This study compared five different methods for analyzing accelerometer-measured physical activity (PA) in older adults and assessed the relationship between changes in PA and changes in physical function and depressive symptoms for each method. Older adult females (N = 144, M_age = 83.3 ± 6.4yrs) wore hip accelerometers for six days and completed measures of physical function and depressive symptoms at baseline and six months. Accelerometry data were processed by five methods to estimate PA: 1041 vertical axis cut-point, 15-second vector magnitude (VM) cut-point, 1-second VM algorithm (Activity Index (AI)), machine learned walking algorithm, and individualized cut-point derived from a 400-meter walk. Generalized estimating equations compared PA minutes across methods and showed significant differences between some methods but not others; methods estimated 6-month changes in PA ranging from 4 minutes to over 20 minutes. Linear mixed models for each method tested associations between changes in PA and health. All methods, except the individualized cut-point, had a significant relationship between change in PA and improved physical function and depressive symptoms. This study is among the first to compare accelerometry processing methods and their relationship to health. It is important to recognize the differences in PA estimates and relationship to health outcomes based on data processing method.

Listening to young people with autism: learning from researcher experiences

This study explores the opportunities and dilemmas that have been encountered by researchers seeking the views of young people with autism. Twelve researchers were interviewed about their experiences in this field. Through exploration of the complex methodological and ethical issues that they encountered, this study aims to better understand how researchers can improve the way they listen to, and engage with, the views of children and young people with autism. This article discusses four themes that emerged from the interviews: power dynamics; building rapport; communication; and meaningful processes and outputs.
