Cortisol in Neonatal Mother's Milk Predicts Later Infant Social and Cognitive Functioning in Rhesus Monkeys 下载免费PDF全文

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. 相似文献

This study describes the context for the development of a tool to formatively assess information technology skills of students. The tool provides a reliable and valid assessment of word processing competency, utilizing automation to apply the test instrument via the Microsoft Office package. Tests can be designed directly by tutors, and delivered via a network. Evaluation of the tests suggests that immediate automated testing is preferred by students compared to a traditional written test. There is evidence that the tool improves the IT skills of its users, whereas a traditional written test has no such beneficial effect. 相似文献

Managerialism and equalities: tensions within widening access policy and practice for disabled students in UK universities 总被引:1,自引:0,他引:1

This paper draws on a four-year longitudinal ESRC funded project examining learning experiences of disabled students in higher
education in four universities. The focus here is on institutional responses to the demands of audit culture and legislation
in relation to making reasonable adjustments for students with impairments. The data comes from institutional documents and
face-to-face interviews with key informants within the institutions. The findings indicate that quality assurance regimes
and legislation have had some positive effect on improving access for disabled students; however, local factors and type of
institution also have a major impact on the way that national policies are expressed in particular contexts. 相似文献

While Northern Ireland strives to build a shared society, the current reality is that everyday experiences are still shaped by division along ethno‐religious lines. This is particularly pronounced in the education system, where more than 92% of pupils attend separate schools. Within the predominantly separate education system, however, exists a small collection of schools which cater to a more heterogeneous pupil body and offer the opportunity for young people from both communities to meet and interact, and potentially develop cross‐group friendships. The present study compares the network‐based cross‐group friendships within two such school types; an integrated and a separate post‐primary school. These schools boast a distinct ethos yet they similarly enrol students from Catholic and Protestant backgrounds. Findings reveal that both schools show a high level of interconnection between pupils; however, the integrated school, with an ethos that openly supports social cohesion, shows a greater tendency towards cross‐group interactions and best friendships than those found within the separate school. In line with contact theory, these findings suggest that it may not be enough to simply create opportunities for intergroup contact but that optimal conditions, such as institutional support, may be a prerequisite for positive relationships to flourish. Implications for educational policies designed to promote greater cross‐community contact are discussed. 相似文献

In this study of the origins of individual differences in theory of mind (ToM), the Environmental Risk (E-Risk) Longitudinal Twin Study sample of 1,116 sixty-month-old twin pairs completed a comprehensive battery of ToM tasks. Individual differences in ToM were striking and strongly associated with verbal ability. Behavioral genetic models of the data showed that environmental factors explained the majority of the variance in ToM performance in this sample. Shared environmental influences on verbal ability had a common impact on ToM and explained more than half the phenotypic correlation between these two skills. Possible underlying proximal mechanisms are discussed, including maternal speech and mind-mindedness, sibling interactions, and peer influences. 相似文献

The school setting represents the most common setting by which youth receive mental and behavioral health (MBH) services (Farmer et al., 2003, Psychiatr Serv, 54, 60–66). Nevertheless, many school psychologists are not providing MBH services despite the high prevalence of need. Additional research is needed to understand factors leading to these deficits, as well as potential solutions to ameliorate these concerns. The current study surveyed 341 school psychologists across seven states and found current ratios are one school psychologist for every 1,500–2,000 students. Study results suggest school psychologists are providing a half to full day of universal, prevention-oriented MBH services each week whereas more targeted, direct services (e.g., individual or small group counseling) are offered 1–4 hr each week. The school psychologist-to-student ratios also demonstrated a statistically significant and inverse association with the provision of targeted MBH services, with higher ratios resulting in fewer MBH services. Respondents provided potential solutions for how to expand the delivery of MBH services within schools, including increased awareness and support among school and district administrators, as well as access to training and professional development related to MBH services. 相似文献

Enthusiasts for new social software do not always acknowledge that belonging to e‐learning communities depends upon complex and often unresolved identity issues for learners. Drawing on the author’s previous research on belonging in social learning, the paper presents a theory of identity congruence in social learning and brings to the foreground the importance of identities which arise from expressions of gender, class, ethnicity, age, etc. in the social, operational and, in particular, the knowledge‐building aspects of learning. These three dimensions of identity congruence are used to evaluate the potential of new social software. While social software might encourage some learners to engage in social and operational identity work, there are disadvantages for others, and learner‐generated knowledge and e‐assessment practices can be divisive. Inclusive e‐learning depends upon pedagogies and assessments which enable learners to shift and transform identities, and not solely on widening the range of technologies available. Such caution should underpin future research. 相似文献

This study investigates the experience of teaching of 19 teachers who are teaching on university courses involving face-to-face and on-line learning. The teachers are asked about how they think about learning technologies and how they approach the design and teaching of their courses across these two contexts. Results show that there are qualitatively different ways of thinking about learning technologies that relate logically and positively to qualitatively different ways of designing and teaching using learning technologies. The results have implications for teachers and those interested in maximising the likelihood of learning for university students when teachers teach with learning technologies. 相似文献

Participation,financial support and the marginal student 总被引:2,自引:0,他引:2
This paper examines differences between the decision-making of marginal and nonmarginal students about participation in higher
education (HE). We distinguish between two kinds of marginality: being ‘borderline’ on account of prior achievements in school
and being ‘unsure’ after taking prior achievement into account. We identify a significant minority of students in their final
year of schooling who are unsure about participation in higher education even though they have prior school achievements typical
of entrants to HE. Being ‘unsure’ is found to be unrelated to socioeconomic background, but it is associated with significantly
different attitudes towards the potential benefits and risks of participation, different levels of knowledge about financial
support that is available and different approaches to information search about participation in HE.
