The ABCs of family mealtimes: observational lessons for promoting healthy outcomes for children with persistent asthma     

Fiese BH  Winter MA  Botti JC 《Child development》2011,82(1):133-145

Family mealtimes have the potential to promote healthy child development. This observational study of 200 family mealtimes examined the relation between child health in a group of children (ages 5 to 12) with persistent asthma and 3 dimensions of mealtime interaction: Action, Behavior Control, and Communication. Percent time spent in Action and Positive Communication varied by asthma severity, child quality of life, and sociodemographic variables. Positive communication during mealtimes predicted child quality of life. Significant interactions between demographic variables and behavior control suggested that higher levels of behavior control affected child quality of life in the context of lower maternal education. Guidance is offered for practitioners and policy makers toward promoting healthy family mealtimes as a public health priority.  相似文献   

Child adaptational development in contexts of interparental conflict over time     

Davies PT  Sturge-Apple ML  Winter MA  Cummings EM  Farrell D 《Child development》2006,77(1):218-233

This multi-method study sought to identify parameters of developmental change and stability of child reaction patterns to interparental conflict in the context of family relations in a sample of 223 6-year-old children and their parents followed over the course of one year. Consistent with the sensitization hypothesis, interparental withdrawal and hostility each consistently and uniquely predicted child distress reactions to conflict even after analytically controlling for parental warmth. Associations were found across multiple domains of child responding (i.e., overt negative affect, subjective negative affect, internal representations) and both concurrent and prospective, autoregressive analyses. Results of the autoregressive path analyses indicated moderate stability in each of the domains of conflict reactivity over the 1-year longitudinal period.  相似文献   

Determinants of range effects in face recognition     

Verbeek EL  Spetch ML  Cheng K  Clifford CW 《Learning & behavior》2006,34(3):229-240

The effects of test stimulus range on generalization gradients in humans were assessed for discriminations between faces that varied in brightness, faces that varied in orientation in the picture plane, and morphed faces. In Experiment 1, significant range effects, predicted by adaptation level theory, occurred when faces varied along the brightness or orientation dimension, but not for morphed faces. Changing the difficulty of discrimination of both training and test stimuli for Experiment 2 produced range effects in morphed faces. Experiment 3 explored training and testing stimulus factors as determinants of range effects in morphed faces. The results suggest that sufficiently biased testing ranges create shifts in response distributions (generalization gradients), and this may be amplified by using relatively difficult discriminations between training stimuli.  相似文献

帮助运动员支持1天进行2次训练   总被引：2，自引：0，他引：2

1天2次的训练通常是美国橄榄球进行比赛季节早期身体条件训练和许多其他运动项目进行常年运动训练的一部分。额外的训练有助于加速身体条件训练，给力量训练和技能发展留出时间，还有助于在队友中发展同志合作精神。1天2次训练的特点是强调体质的适应性。在夏季训练时，运动员频繁地置身于附加的湿热环境应激下。我们专家组就1天2次训练中的高能量需要、有限的恢复时间和“制造伤口”的心理应激问题进行讨论，基于科学理论和临床经验提出帮助运动员在1天2次的训练中获得最大的成效的策略。  相似文献   

Gaining and Sustaining TEL in a 1:1 Laptop Initiative: Possibilities and Challenges for Teachers and Students     

Marcia J. P. Håkansson Lindqvist 《学校用计算机》2015,32(1):35-62

The uptake and use of digital technologies is studied in Unos Umeå, a joint one-to-one (1:1) research project between Umeå University and the municipality of Umeå in Sweden. This article presents the results of the third phase of the classroom work with laptops. Using the ecology of resources model (Luckin, 2010), these possibilities and challenges can be interpreted as the manifestation of filters in the learning environment. Alleviating technical problems, targeting low student laptop use, teacher collaboration, and teacher professional development (TPD) may help teachers and students gain and sustain technology-enhanced learning (TEL) in this 1:1 initiative.  相似文献

Compliance with freedom of information legislation by public bodies in South Africa     

Marcia Nkwe  Mpho Ngoepe 《Government Information Quarterly》2021,38(2):101567

In South Africa, freedom of information (FOI) is entrenched in section 32 of the Constitution, which guarantees every citizen the right of access to any information held by the state or by any other person that is to be used for the protection or exercise of any right. The Promotion of Access to Information Act (PAIA) is the law that gives effect to section 32 of the Constitution. Regardless of a remarkable trend towards the adoption of FOI laws, international trends have shown this does not automatically translate into fulfilment of people's right to information. This study utilised mixed method research through the explanatory sequential design to assess compliance with FOI legislation by public bodies in South Africa, with a view to develop a model for implementation of FOI. The study first conducted a quantitative study by analysing the reports of the South African Human Rights Commission from the reporting years 2006/07 to 2016/07 to assess compliance with sections 14, 15, 16, 17 and 32 of the PAIA. Thereafter, a qualitative study through interviews with purposively chosen participants was conducted to substantiate the findings of a quantitative study. Key results suggest that over the years, there were problems in the implementation of the FOI legislation in South Africa and its use was limited. Where implementation has taken place, it has been partial and inconsistent. The responsibility for the implementation of FOI legislation in most public bodies is assigned to legal departments that do not have knowledge of what records are created, and where and how they are kept. With regard to compliance, in terms of the degree of comparison, the situation was better in national departments, worse in provincial departments and worst in municipalities. The study recommends the establishment of an information governance unit to implement FOI in public bodies. Failure to assign responsibility to a relevant unit would perpetuate the non-compliance with FOI legislation by public bodies in South Africa. A model for the implementation of PAIA within a public body is suggested.  相似文献
