The neo‐Darwinian paradigm, focusing on natural selection of genes responsible for differential adaption, provides the foundation for explaining evolutionary processes. The modern synthesis is broader, however, focusing on organisms rather than on gene transmissions per se. Yet, strands of current biology argue for further supplementation of Darwinian theory, pointing to nonbiotic drivers of evolutionary development, for example, self‐organization of physical structures, and the interaction between individual organisms, groups of organisms, and their nonbiotic environments. According to niche construction theory, when organisms and groups develop, they not only adapt to their environments but modify their environments, creating new habitats for later generations. Insofar as ecological niches persist beyond the lifecycle of individual organisms, an ecological inheritance system exists alongside genetic inheritance. Such ecological structures may even facilitate the development of a cultural inheritance system, as we see in humans. The article discusses theological perspectives of such new developments within holistic biology.  相似文献

内/外参照模型在理论上同时考虑了社会比较和维度比较两种比较方式在建构个体学业自我概念过程中的作用。近年来,对内/外参照模型的研究进展主要体现在三个方面:对该模型进行跨文化一致性检验;提出了维度比较理论;与大鱼小池效应相整合。这些研究表明学业自我概念具有学科特异性,研究者要更加注重学业自我概念及其它学业变量的学科特异性研究,并加强内/外参照模型的调节因素研究,教师及家长要引导学生合理选择比较方式。  相似文献

Using data from the first three waves (Grades 5, 6, and 7) of the 4-H Study of Positive Youth Development, this study assessed if being a bully or being a victim accounts for an adolescent's academic competence, if selected contextual and individual variables impact an adolescent's academic competence, and if such impact differs in relation to an adolescent's bullying status. The results of random coefficient hierarchical regression analyses indicated that being a bully predicted lower grades across time, and that being a bully was more detrimental for girls than for boys. Being a bully and being a victim negatively predicted self-perceived academic competence, but these predictive effects did not change over time or differ by sex. Teacher support positively predicted grades and greater parent support and teacher support independently predicted higher self-perceive academic competence. Greater educational expectations and school engagement independently predicted higher self-reported grades, while these two predictors positively interacted in explaining self-perceived academic competence. Unexpectedly, peer support negatively predicted self-reported grades for victims, and negatively predicted self-perceived academic competence for bullies. We discuss the importance of addressing the issue of academic competence in bullying interventions, as well as the utility of capitalizing on developmental assets in promoting academic competence among adolescents who bully and who are bullied.  相似文献

The hypothesis that shyness would be associated with attribution of emotional reactions to stable internal causes rather than to less stable internal and external causes was tested in Study 1 (N = 60). In Study 2 (N= 112) the hypothesis that the explanatory power of shyness would decrease once the effect of self-focused attention on attribution to stable internal causes had been controlled for was tested. The results confirmed both hypotheses. Shyness correlated positively with attribution to stable internal causes, but non-significant with attribution to less stable internal and external causes. Shyness explained a lesser portion of the variance in attribution to both of the internal causes when controlling for self-focus. Even though the findings indicate that self-focus is central to the social cognitive processes of shy individuals, they also suggest that self-focus cannot fully explain attribution to internal causes in general and shy individuals' attributional pattern in particular.  相似文献

In seeking to understand factors contributing to team creativity in dynamic environments, we explored the role of external knowledge search on team creativity through absorptive capacity and knowledge integration. We tested our hypotheses with a sample of 96 teams involving 421 employees in China. Results demonstrated that external knowledge search related positively to team creativity, fully mediated by both absorptive capacity and knowledge integration. In addition, environmental dynamism played a moderating role in the relation between external knowledge search and absorptive capacity, as well as in the relation between external knowledge search and knowledge integration. We discussed the implications of these findings for research and practice.  相似文献

In this paper I will discuss certain aspects of Leibniz's theory and practice of ‘soft reasoning’ as exemplified by his defence of two central mysteries of the Christian revelation: the Trinity and the Incarnation. By theory and practice of ‘soft’ or ‘broad’ reasoning, I mean the development of rational strategies which can successefully be applied to the many areas of human understanding which escape strict demonstration, that is, the ‘hard’ or ‘narrow’ reasoning typical of mathematical argumentation.1 These strategies disclose an ‘other’ reason, i.e. a complementary set of arguments and methods developed by Leibniz in order to deal with crucial issues such as the ‘weighting’ of probabilities and truths of fact. I will argue that one of the most compelling examples of the importance and fertility of Leibniz's ‘other’ reason is provided by his solution to the problems posed by the unique epistemological status of theological mysteries.  相似文献

Objectives : The research explored (1) the relationships between self-reported eating style (restraint, emotional and external eating) and dietary intake and (2) emotional eater status as a moderator of food intake when emotional, in a morbidly obese population.

Design : A sample of 57 obese participants (BMI: M?=?51.84, SD?=?8.66) completed a five-day food diary together with a reflective diary, which assessed eating style and positive and negative affect daily.

Main outcome measures : A dietician-scored food pyramid analysis of intake.

Results : Restraint eating was the only predictor (negative) of overall food intake and the variable most strongly associated with the consumption of top-shelf foods. Emotional and external eating were unrelated to food intake. Emotional eater status did not moderate food intake in response to positive and negative mood states.

Conclusion : The findings indicated largely analogous relationships between eating style and dietary intake in this obese sample compared with previous results from healthy populations. The lack of predictive validity for emotional eating scales (when emotional) raises questions over people’s ability to adequately assess their eating style and consequently, the overall validity of emotional eater scales.  相似文献

Abstract

This study explores whether and how different external representations of quantity influence the performance of four-year-old children when constructing sets of a given cardinal number. Three representations of quantity were presented (objects, pictures and number words) in an adaptation of the ‘Give-a-number’ task, in sets that contained 2–6 items. The results show that the use of pictures facilitated children’s performance with quantities of three and four. These results are discussed by analysing the cognitive demands of representational formats, in terms of dual representation and iconicity, and according to the magnitude of the quantities involved.  相似文献
