The current study examines the association between parental support and adolescent sleep under varying levels of family stress. Participants included 316 adolescents (Mage = 16.40 years, 43% male) and their parents (Mage = 45.67 years, 91% mothers) from diverse ethnic backgrounds. Both adolescents and parents completed questionnaires and adolescents wore wrist actigraphs and completed self‐reports on their sleep for 7 consecutive days. Results indicated that under contexts of family stress, more parental support was linked to longer sleep duration, less sleep variability, and less time spent awake during the night. Findings suggest that under contexts of family stress, cohesive family relationships may provide a sense of stability and security that is necessary for healthful sleep.  相似文献

The present article gives an outline of the state of art in computer assisted intervention by learning-concomitant differential feedback. Based on the spectrum of possible meanings and interpretations given to the concepts ‘interaction’ and ‘interactive’ this concept is elaborated and illustrated by prototypical theoretical approaches. Based on our own empirical findings arguments are given showing that sophisticated audiovisual interactive new technologies can properly be used even on the small machines available in schools if the content materials and the flow of control given to the learner are carefully designed and based on principles of cognitive science.

This study examines regret for withholding relational complaints. The study sample of 393 participants completed measures of irritant frequency, irritant importance, relational intimacy, emotional distress from withholding, and regret for withholding. Irritant frequency mediated the positive relationship between length of withholding and irritant importance. This process predicted less intimacy and more emotional distress from withholding, the latter of which related to regret. Alternative paths were also found between length of withholding and regret. Results offer important implications for the role of regret management in hurtful confrontations and may inform other avoidance forms.  相似文献

This paper concludes that it is time for institutional research to address the issue of standards for the conduct of surveys. In reaching that conclusion, it argues that executing surveys is one of the most common activities of institutional research (IR) and one of the least served in IR literature; that as a craft, survey research is an orphan without a home in an academic discipline and therefore without a clear articulation of standards in its own right; and that as practiced in IR, survey research faces special technical problems and challenges not embraced in much of the general-survey research literature. Finally, it asks, but does not answer, how such a lofty goal as the pursuit of standards might be attained.  相似文献

Literacy education in Nigerian history finds its roots in the efforts of missionary endeavour. Subsequent work in the field has always been piecemeal and unco-ordinated, even though a degree of success has been achieved and valuable experience gained. The Federal Government's decision to launch a Mass Literacy Campaign in 1982 is primarily a political response to the needs and exigencies of a developing country rich both in natural and manpower resources. The campaign is seen not only as a necessary means of creating a permanently literate society within ten years but also as an assertion of the nation's unity. The problems of undertaking such a project are immensely complicated by the plethora of local languages and cultures, the preservation of which is seen to be imperative. But the campaign can succeed if the crucial issues identified in the article — functionality, personnel, training and materials, motivation, and above all the language to be used as the medium of literacy education — are resolved; if assistance from national development organisations and international bodies is matched by the determination of the government to create an environment capable of sustaining and reinforcing literacy and conducive to the use of the skills acquired; and if the illiterate respond with initiative and perseverence to the opportunity offered them.
Zusammenfassung Die Alphabetisierung in Nigeria hat ihre historischen Wurzeln in missionarischen Bemühungen. Alle spätere Arbeit auf diesem Gebiet war stückenhaft und unkoordiniert, wenn ihr auch ein gewisses Maß von Erfolg beschieden war und wertvolle Erfahrungen gemacht wurden. Der Beschluß der nigerianischen Regierung, im Jahre 1982 eine Massen-Alphabetisierungskampagne durchzuführen, ist vor allem eine politische Antwort auf die Bedürfnisse und Erfordernisse eines an natürlichen und menschlichen Ressource reichen Entwicklungslandes. Die Kampagne wird nicht nur als notwendiges Mittel angesehen, innerhalb von zehn Jahren eine bleibend alphabetisierte Gesellschaft zu schaffen, sondern auch als eine Bestätigung der Einheit der Nation. Die einem solchen Projekt anhaftenden Probleme werden durch die Vielfalt einheimischer Sprachen und Kulturen, deren Erhaltung als unerläßlich betrachtet wird, außerordentlich kompliziert. Dennoch kann das Unternehmen zum Erfolg führen, wenn die wichtigsten, in diesem Artikel herausgearbeiteten Fragen — Funktionalität, Personal, Ausbildung und Materialien, Motivation und besonders die für die Alphabetisierung benutzte Sprache — gelöst werden; wenn der Unterstützung durch nationale Entwicklungsstellen und internationale Organisationen eine entsprechende Entschlossenheit der Regierung gegenübersteht, eine Umgebung herzustellen, die die Alphabetisierung aufrechterhalten und konsolidieren kann und zum Gebrauch der erworbenen Fähigkeiten herausfordert; und wenn die Analphabeten die ihnen gebotene Gelegenheit mit Initiative und Ausdauer nutzen.

Résumé L'alphabétisation dans l'histoire nigériane prend sa source dans les efforts des missions religieuses. Le travail postérieur dans ce domaine a toujours été fragmentaire et sans coordination, bien qu'on ait atteint un certain degré de succès et qu'on ait acquis une expérience précieuse. La décision du Gouvernement Fédéral de lancer une Campagne d'Alphabétisation Massive en 1982 est avant tout une réponse politique aux besoins et aux exigences d'un pays en développement riche en ressources tant naturelles qu'humaines. Cette campagne est considérée non seulement comme un moyen nécessaire de créer une société définitivement alphabète en dix ans mais aussi comme une assertion de l'unité de la nation. Les problèmes soulevés par l'entreprise d'un tel projet sont énormément compliqués par la pléthore des langues et des cultures indigènes, dont la préservation est regardée comme impérative. Néanmoins, cette campagne a des chances de réussir si les points critiques identifiés dans cet article — fonctionnalité, personnel, formation et matériel, motivation, et par dessus tout la langue à employer comme véhicule de l'alphabétisation — sont résolus; si l'assistance accordée par les organisations pour le développement national et par les organismes internationaux rencontre sur le même niveau la détermination du gouvernment de créer un environment capable de maintenir et de renforcer l'alphabétisation qui soit aussi favorable à l'utilisation des connaissances et de l'expérience acquises; et si les illettrés répondent par la persévérance et par l'initiative aux occasions qui leur sont offertes.

A novel “Whiteheadean” science program was initiated in England and Wales in September 2006. Following a critical House of Commons report in 2002, the government altered the National Curriculum targets and thus forced the Examination Boards to alter their specifications in order to come in line. Assessment at GCSE level (i.e., the 14-16 year cohort) was criticised for: a) failing to inspire students to continue with science, b) discouraging students from thinking for themselves, c) neglecting contemporary science, d) lacking flexibility, and e) making practical work into a tedious and dull activity. The British government has insisted that all pupils in state funded schools must know the names of some modern scientists and their work. They must discuss some current scientific problems. History and philosophy of science is included under the topic heading “How Science Works.” In Chemistry these objectives have destroyed the traditional linear top-down sequential approach of teaching into an approach based more closely on Whiteheadean lines (cf., the ideas expressed in The Aims of Education, 1926, Chapters 1-3).  相似文献

This essay considers the question of why we should teach science to K-2. After initial consideration of two traditional reasons for studying science, six assertions supporting the idea that even small children should be exposed to science are given. These are, in order: (1) Children naturally enjoy observing and thinking about nature. (2) Exposing students to science develops positive attitudes towards science. (3) Early exposure to scientific phenomena leads to better understanding of the scientific concepts studied later in a formal way. (4) The use of scientifically informed language at an early age influences the eventual development of scientific concepts. (5) Children can understand scientific concepts and reason scientifically. (6) Science is an efficient means for developing scientific thinking. Concrete illustrations of some of the ideas discussed in this essay, particularly, how language and prior knowledge may influence the development of scientific concepts, are then provided. The essay concludes by emphasizing that there is a window of opportunity that educators should exploit by presenting science as part of the curriculum in both kindergarten and the first years of primary school.  相似文献
