ABSTRACT

The aims of this study were to identify profiles of sedentary behaviour (SB) patterns, based on leisure-time self-reported SB modalities (screen, educative, social, and relaxing) and to evaluate changes in these profiles over 2 years among Spanish youth aged 8–18 years. Latent profile analysis (LPA), a data-driven analytic approach, was used to identify groups of boys and girls (n = 1553; 48% girls; mean±SD age: 12.56 ± 2.49 y) with distinct SB profiles using the SB modalities (time/d) as input variables. Latent transition analysis, an extension of LPA that uses longitudinal data, was used to analyse 2-year changes in these profiles. At baseline, four and three SB profiles were found among boys (labelled: screen, educative, social, and relaxing) and girls (labelled: screen/social, educative, and relaxing), respectively. Overall, more girls (range: 48%-67%) had the same profile over time, than boys (40%-52%). Participants with a screen or relaxing SB profile at baseline were more likely to have an educative profile after 2 years. Youth with a social and an educative SB profile at baseline were more likely to transition to profiles characterized by higher screen and social SB, respectively. Using a novel and person-centered approach, this study identified gender-specific SB profiles that were moderately stable over time.  相似文献   

Adaptation and evaluation of a learning analytics dashboard to improve academic support at three Latin American universities

Despite the success of academic advising dashboards in several higher educational institutions (HEI), these dashboards are still under-explored in Latin American HEI's. To close this gap, three different Latin American universities adapted an existing advising dashboard, originally deployed at the KU Leuven to their own context. In all three cases, the context was the main ruling factor to these adaptations. In this paper, we describe these adaptions using a framework that focuses on four different elements of the context: Objectives, Stakeholders, Key moment and Interactions. Evaluation of the adapted dashboards in the three different Latin American universities is conducted through pilots. This evaluation shows the value of the dashboard approach in different contexts in terms of satisfaction, usefulness and impact in academic decision-making and advising tasks. The main contribution of this paper is the systematic reporting of the adaptations to an academic advising dashboard and showing the value of an academic advising dashboard on academic decision-making and advising tasks.  相似文献   

The effect of use and access on citations     

Michael J. Kurtz  Guenther Eichhorn  Alberto Accomazzi  Carolyn Grant  Markus Demleitner  Edwin Henneken  Stephen S. Murray 《Information processing & management》2005,41(6):1395-1402

It has been shown (Lawrence, S. (2001). Online or invisible? Nature, 411, 521) that journal articles which have been posted without charge on the internet are more heavily cited than those which have not been. Using data from the NASA Astrophysics Data System (ads.harvard.edu) and from the ArXiv e-print archive at Cornell University (arXiv.org) we examine the causes of this effect.  相似文献   

The dynamics of connecting universities,non-governmental organizations and community members by means of academic projects directed at people in need     

João Alberto Arantes do Amaral  Cristina Toshie Motohashi Matsusaki 《Educational Action Research》2017,25(2):280-299

In this article we discuss an action research experience that took place from 2002 to 2015. We analyze the inception and progress of several project-based learning-centered academic courses that were aimed at developing the project management skills of graduate and undergraduate students. The experience involved approximately 1800 students from two universities and 40 community partners. The students developed real-life projects on behalf of institutions and non-governmental organizations located in the area that help people in need; we refer to these agencies as ‘community partners.’ We analyze the development of the course from a systemic perspective, making use of causal loop diagrams in order to understand the main driving dynamics. We discuss the results achieved by these projects and the benefits brought to the community partners. We also present testimony from the community partners themselves. We conclude by presenting the lessons we learned over the years we have been running this course.  相似文献   

The Role of Bilingualism in Shaping Engineering Literacies and Identities     

Erika Mein  Alberto Esquinca 《理论付诸实践》2017,56(4):282-290

In this article, we demonstrate ways in which teachers, working within the context of rapidly changing demographics in our country, can create inclusive classroom environments that promote the development of engineering literacies and identities, particularly among bilingual students. We draw on our experience working with two projects funded by the U.S. Department of Education’s Minority Science and Engineering Improvement Program (MSEIP) at a large public university on the U.S.-Mexico border to show how educators can create educational spaces that encourage bilingual students to use their full communicative repertoires in developing engineering discourses and identities. In so doing, we highlight the relationship between bilingualism and disciplinary literacy development; describe how hybrid language practices such as translanguaging can contribute to engineering learning; and highlight the role of identities in disciplinary discourses. The practices illustrated in this article have implications not only for college instructors, but also for teachers at the secondary level.  相似文献   

Privatization And Vouchers In Colombia And Chile     

Alberto?ArenasEmail author 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2004,50(3-4):379-395

The voucher model of financing schooling is becoming increasingly common throughout Latin America, with at least 12 countries using vouchers or voucher-like schemes. The present study focuses on the voucher models of Colombia and Chile, which have the most extensive programs of this type and those of the longest standing in the region. Using empirical evidence, the author compares the two models along four evaluative dimensions: educational quality, segregation, choice and socialization. After weighing the successes and weaknesses of each system, he concludes that, among other characteristics, the most effective and equitable voucher model features: (a) a flexible interpretation of educational quality; (b) financial grants which target solely the poor; (c) vouchers which cover the entire cost of tuition; (d) open enrolment at participating schools; (e) the participation of both secular and religious private schools; (f) accessible and meaningful information to parents; and (g) strong systems of accountability.  相似文献

The robed baron: The academic profession in the Italian university     

Martinotti  Guido  Giasanti  Alberto 《Higher Education》1977,6(2):189-207

The Italian academic profession is subject to complex bureaucratic structures and many strains as the result of rapid academic expansion but very limited resources. The ladder up the academic profession is both complicated and very difficult. Norms of professionalism are in conflict with the traditional patron system. This paper analyzes the current situation of the academic profession in Italian universities, and stresses a discussion of the career ladder and how it works in the academic system.Data for this paper have been collected as part of a research grant no. 73.00982.09 from the Consiglio Nazionale delle Ricerche.  相似文献   

Ecole et communaute au Portugal     

Alberto Melo 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》1980,26(3):325-334

Résumé Depuis 1974 le Portugal a fait l'expérience de changements spectaculaires dans les pratiques de l'enseignement au niveau local. L'école a été ouverte à la communauté et la communauté à l'école. Le programme de formation des enseignants comprend maintenant une nouvelle matière: l'étude de la communauté afin de les préparer au rôle actif d'ouvrir l'école à la communauté et de les aider à mieux comprendre les différents milieux sociaux dont sont issus leurs élèves. Parmi les innovations il convient de noter la publication de journaux ou bulletins d'information locale qui aide les enseignants et les élèves à mieux comprendre la communauté à laquelle ils appartiennent. La création d'un jardin scolaire où les élèves cultivent fleurs et légumes jette un pont supplémentaire entre l'école et la communauté. Autres exemples d'action de la communauté: les classes d'alphabétisation des adultes, la création de mouvements volontaires de femmes, l'organisation de clubs de jeunes, la constitution de coopératives, les initiatives locales comme d'acheter un vieux tramway pour le transformer en bibliothèque. Une des innovations les plus importantes a été l'introduction de 'l'Education Civique et Polytechnique' à l'école (classes de 13 à 16 ans). Deux heures par semaine devaient être consacrées à une intervention active de l'école dans la communauté locale, à l'engagement des jeunes, agents d'évolution, dans la vie de la société, à l'articulation entre les études scolaires et l'application pratique, au travail social et productif, et à la participation des jeunes à la solution des problèmes nationaux, en partant d'une connaissance concrète de la vie locale et régionale. Cependant, depuis 1976, la politique de l'enseignement au Portugal a pris une tournure plus conservatrice et ce n'est que dans localités où le consensus du corps enseignant a été très fort que les relations nouvelles entre l'école et la communauté ont pu être maintenues.

Since 1974 Portugal has experienced some dramatic changes in educational practices at the local level. The school has been opened to the community and the community to the school. Teacher education now includes community studies, designed to prepare teachers for an active role in this process and for the better understanding of the social background of pupils. One new practice is the publication of local newspapers or news-sheets to enhance the understanding of the community by teachers and pupils. The development of a school garden for the cultivation of flowers and vegetables serves as another bridge between school and community. Other examples of community action are adult literacy classes, the creation of voluntary organisations for women, the running of youth clubs, the formation of co-operatives, and local projects like the purchase of an old tram-car to be converted into a library. The introduction of Civic and Polytechnic Education for 13–16 year olds was an important innovation. One half-day a week was to be devoted to the integration of the school with the locality, young people's participation in society as agents of change, the linking of study and productive work, and the involvement of young people in the solution of national problems, working from a concrete knowledge of local and regional life. However, since 1976 there has been a more conservative approach, and only in places with a strong consensus amongst teachers has the new relationship between school and community been maintained.

Zusammenfassung Ab 1974 hat Portugal auf örtlicher Ebene ein paar dramatische Veränderungen in der Bildungspraxis erfahren. Die Schule wurde für das Gemeinwesen aufgeschlossen und das Gemeinwesen für die Schule. Nunmehr umfaßt die Lehrerbildung Studien des Gemeinwesens, dazu bestimmt, die Lehrer auf eine aktive Rolle in diesem Prozeß und auf ein besseres Verständnis für die soziale Herkunft der Schüler vorzubereiten. Eine der neuen Praktiken ist die Veröffentlichung lokaler Zeitungen oder Mitteilungsblätter, damit Lehrer und Schüler das Gemeinwesen gründlicher verstehen lernen. Eine weitere Brücke zwischen Schule und Gemeinwesen schlägt die Anlage eines Schulgartens zur Anzucht von Blumen und Gemüse. Andere Beispiele von Aktivitäten für das Gemeinwesen sind Klassen zur Alphabetisierung Erwachsener, der Betrieb von Jugendklubs, die Schaffung von Kooperativen und örtliche Projekte wie der Ankauf eines alten Straßenbahnwagens, um ihn in eine Bibliothek umzuwandeln. Die Einführung einer staatsbürgerlichen und polytechnischen Bildung für 13- bis 16-jährige war eine wichtige Neuerung. In jeder Woche sollte ein halber Tag der Integration der Schule in die örtliche Umwelt gewidmet sein, der Mitwirkung junger Leute in der Gesellschaft als Agenten des Wandels, der Verknüpfung des Lernens mit der produktiven Arbeit und der Beteiligung junger Menschen an der Lösung nationaler Probleme aufgrund einer konkreten Kenntnis des örtlichen und regionalen Lebens. Allerdings kam es ab 1976 zu einem konservativeren Ansatz, und nur dort blieb die Neue Beziehung zwischen Schule und Gemeinwesen aufrechterhalten, wo ein starker Konsens der Lehrer untereinander bestand.
