Dr Lesley Cullen-Powell and Professor Julie Barlow are both chartered health psychologists and both work at the Interdisciplinary Research Centre in Health at Coventry University where Lesley Cullen-Powell is a research fellow and Julie Barlow is a director. In this article, they assess the benefits of a 'self-discovery programme' for children aged six to seven years attending one mainstream primary school. Staff at the school selected 18 pupils, many of them considered to be at risk of exclusion, to participate in the study. The children were allocated either to an 'intervention' or 'non-intervention' group. The children in the intervention group experienced the self-discovery programme over two terms.
Results suggest that the programme was well received by the children. They became more confident, respectful and calm and they displayed less aggressive behaviours during the self-discovery programme. Lesley Cullen-Powell and Julie Barlow are cautious in the interpretation of their findings, but suggest that the self-discovery programme has the potential to help children to feel more positive about themselves and their peers and to re-engage with learning. The authors argue that a wider implementation of the programme, with a controlled study, is now required to evaluate the self-discovery programme in more depth and detail.  相似文献

In this study, we identified 10 sexuality education programmes from different locations in the USA that aim to give young people knowledge and skills to develop healthy relationships, as well as avoid pregnancy and disease. We conducted in-depth interviews with programme administrators to develop a series of case studies and provide concrete recommendations for education and public health professionals to implement similar approaches in their communities. Many programme administrators succeeded in developing partnerships, adapting existing curricula to suit their environments, engaging external evaluators and garnering support from teachers and parents. However, few programme developers conducted formal needs assessments before developing programmes and many struggled to implement curricula with fidelity and to employ rigorous evaluation designs. Nearly all participants identified concerns over funding as a threat to sustainability. We conclude that schools and organisations need technical assistance to build capacity for rigorous programme planning, implementation and evaluation, as well as additional funding streams to support emerging programmes.  相似文献

Based on research in universities in the North of England, this article reflects on the growing size and widening remit of the personnel function. Differences between the old and new universities are discussed together with the possible future roles of personnel within higher education. The author feels that it is unlikely, given personnel directors views of the way the personnel function is seen by Vice Chancellors and Pro-Vice-Chancellors in the older universities, that the personnel function will play a more influential role in the immediate future. Also, despite a greater role being played by the personnel function in the new universities, a seat at the'top table'has generally been denied. The author concludes that in such labour-intensive organizations as universities, the failure to empower the personnel function is somewhat shortsighted given the growing number of government policies directed towards the activities of academic staff.  相似文献

Effects of competition, exercise, and mental stress on secretory immunity   总被引:2,自引:0,他引:2  
It has been suggested that the psychological stress associated with competitive sports events may help to explain the increased susceptibility to respiratory infections due to reductions in secretory immunity. In the current study, we investigated the influence of competitive exercise and psychological stress on secretory immunoglobulin A (s-IgA). Salivary s-IgA and heart rate were measured in 62 healthy young recreationally active men at rest and, in a between-subjects design, following one of four 8-min tasks: mental arithmetic, cycling at workloads of 60 to 180 W (mean = 146 W), mental arithmetic while cycling, or competitive cycling. Mental arithmetic was associated with significant increases in s-IgA concentration (mean = 49 microg.min(-1)) and s-IgA secretion rate (mean = 25 microg.ml(-1)) compared with rest, while mental arithmetic combined with exercise was associated with a significant increase in s-IgA concentration only (mean = 124 microg.min(-1)). In contrast, competitive exercise and exercise alone did not influence s-IgA concentration or secretion rate. Heart rate increased modestly to mental arithmetic (mean = 7 beats.min(-1)) and substantially, and similarly, to the three exercise tasks (mean = 56(62 beats.min(-1)). The hypothesis that the psychological stress of competitive exercise contributes to increased susceptibility to infection via reductions in s-IgA requires further investigation.  相似文献

Embryoid body (EB) formation forms an important step in embryonic stem cell differentiation invivo. In murine embryonic stem cell (mESC) cultures EB formation is inhibited by the inclusion of leukaemic inhibitory factor (LIF) in the medium. Assembly of mESCs into aggregates by positive dielectrophoresis (DEP) in high field regions between interdigitated oppositely castellated electrodes was found to initiate EB formation. Embryoid body formation in aggregates formed with DEP occurred at a more rapid rate-in fact faster compared to conventional methods-in medium without LIF. However, EB formation also occurred in medium in which LIF was present when the cells were aggregated with DEP. The optimum characteristic size for the electrodes for EB formation with DEP was found to be 75-100 microns; aggregates smaller than this tended to merge, whilst aggregates larger than this tended to split to form multiple EBs. Experiments with ESCs in which green fluorescent protein (GFP) production was targeted to the mesodermal gene brachyury indicated that differentiation within embryoid bodies of this size may preferentially occur along the mesoderm lineage. As hematopoietic lineages during normal development derive from mesoderm, the finding points to a possible application of DEP formed EBs in the production of blood-based products from ESCs.  相似文献
