Adolescence is marked by the development of personal identity and is associated with structural and functional changes in brain regions associated with Self processing. Yet, little is known about the neural correlates of self‐reference processing and self‐reference effect in adolescents. This functional magnetic resonance imaging study consists of a self‐reference paradigm followed by a recognition test proposed to 30 healthy adolescents aged 13–18 years old. Results showed that the rostral anterior cingulate cortex is specifically involved in self‐reference processing and that this specialization develops gradually from 13 to 18 years old. The self‐reference effect is associated with increased brain activation changes during encoding, suggesting that the beneficial effect of Self on memory may occur at encoding of self‐referential information, rather than at retrieval. 相似文献

The giant panda (Ailuropoda melanoleuca) is an iconic bear native to China, famous for eating almost exclusively bamboo. This unusual dietary behavior for a carnivore is enabled by several key adaptations including low physical activity, reduced organ sizes and hypothyroidism leading to lowered energy expenditure. These adaptive phenotypes have been hypothesized to arise from a panda-unique single-nucleotide mutation in the dual-oxidase 2 (DUOX2) gene, involved in thyroid hormone synthesis. To test this hypothesis, we created genome-edited mice carrying the same point mutation as the panda and investigated its effect on metabolic phenotype. Homozygous mice were 27% smaller than heterozygous and wild-type ones, had 13% lower body mass-adjusted food intake, 55% decreased physical activity, lower mass of kidneys (11%) and brain (5%), lower serum thyroxine (T4: 36%), decreased absolute (12%) and mass-adjusted (5%) daily energy expenditure, and altered gut microbiota. Supplementation with T4 reversed the effects of the mutation. This work uses a state-of-the-art genome editing approach to demonstrate the link between a single-nucleotide mutation in a key endocrine-related gene and profound adaptive changes in the metabolic phenotype, with great importance in ecology and evolution. 相似文献

La coopération internationale entre établissements d'enseignement supérieur et plus précisément entre établissements formant des ingénieurs relève encore bien souvent du paradoxe: on en parle comme d'une nécessité évidente, mais la désire-t-on vraiment et la pratique-t-on en sachant bien ce que l'on fait? 相似文献

Summary This article sums up a survey carried out on pupils of 15 to 18 years of age to study the relations existing between mathematics and affectivity. Pupils were considered according to their sex and whether they were in literary or scientific streams.This work has been carried out according to a clinical method based on 60 recorded interviews and also according to an experimental method based on 600 sets of questions. Its objective was to show in which way mathematics can be considered as a support for libidinal cathexis used by the unconscious through various mechanisms.This research work has been published in: Mathématique et Affectivité, Édition Stock, Paris. 相似文献

Typology of students at risk of dropping out of school: Description by personal, family and school factors 总被引:1,自引:0,他引:1

The purpose of this study was to identify the different subgroups of students at risk of dropping out of school. The typology
was developed based on the three main contexts associated with school dropout risk, namely, the personal, family and school
contexts. On the basis of these factors, the clustering results enabled us to categorize at-risk students into four subgroups:
(1) the Anti-Social Covert behavior type, (2) the Uninterested in school type, (3) the School and Social Adjustment Difficulties
type, and (4) the Depressive type. Moreover, considering all the contexts involved in school dropout, the clustering technique
confirms the importance of behavior problems and learning difficulties, while emphasizing the significance of both depression
and the family and classroom environments in the development of dropout risk. Students at risk of dropping out of school report
many family organisational problems and that they obtain little emotional support from their parents. They also perceive little
order or organisation in the classroom. 相似文献

This study was designed to determine whether the more favorable learning conditions provided by mastery learning procedures result in higher levels of achievement and more internal attributions on the part of college students. One hundred twenty-two undergraduate students enrolled in a general education course at a large state university participated in the study. Results showed that although students in mastery-taught sections did attain significantly higher levels of achievement no differences in attribution change were identified. Possible reasons for the lack of attribution change are discussed.An earlier version of this paper was presented at the annual meeting of the American Educational Research Association Montreal, Canada, 1983. 相似文献

The objective of this qualitative study was to establish motivations for participation of non-traditional students (NTS) in university education. The findings are drawn from empirical data collected from 15 unstructured in-depth interviews with NTS of the School of Computing and Informatics Technology at Makerere University, and analysed with the aid of qualitative data analysis software ATLAS.ti. Three major findings were established: (1) motivations were found to be multiple, multifaceted and varied for each individual; (2) the sociocultural context of the African society including societal perceptions of university education were found to be the major factor shaping motivations of NTS to upgrade their educational qualifications; and (3) most motivations were found to be extrinsic in nature rather than intrinsic and based more on push rather than pull factors. Yet, although the demand for university education is increasing, life beyond university can no longer guarantee some of the anticipated rewards such as employment and its related benefits. It therefore becomes important that the purpose of education within universities in Africa is directed towards achieving development of the whole human being. In this way, a graduate’s capacity to function will not be seen only in the economic and professional life, but also in other spheres of life. 相似文献
