Video games are a very common leisure activity among teenagers and the aim of this study is to analyse their relations with cognitive and school performances. This study is part of a broad survey, conducted on 27,000 French teenagers (14.5?years old) in middle school (9th grade). The survey contained both a questionnaire on leisure activities practised by teenagers and school/cognitive tests: Comprehension tests, Math, School Knowledge, and Reasoning. The activity frequency (‘never’ to ‘every day or almost’) is studied on five kinds of video games (i.e. action/fighting) vs. seven reading activities (i.e. crime/thriller/fantasy). Results show that there are no correlations or very slight ones between Video Games and cognitive/school tests. Reading activities have potentially important associations with cognition and especially school tests. To conclude, video games are primarily recreational activities and the cognitive stimulation they produce is very different from the one involved in specialised academic subjects  相似文献   

Equal educational opportunity and declining teacher morale at black,white, and Hispanic high schools in a large urban school district     

James E. Bruno 《The Urban Review》1983,15(1):19-36

School desegregation plans and program efforts in bilingual education, special education, compensatory education, and others designed to promote equal educational opportunity for minorities are threatened with a teaching staff best described as being “burned out,” highly stressed, of low morale, having high absenteeism, and subject to physical abuse. This study examines the extremely low level of teacher morale at inner-city schools and finds major “ethical” stressors such as racial tension among faculty, falsifying of school records, and sexual harassment by school officials emerging as factors contributing to teacher exit and absenteeism. With the use of multivariate discriminant analysis procedures and a sample of 400 high school teachers at nine high schools (three black, three white, and three Hispanic in terms of predominant ethnicity), a set of stressors were derived which uniquely characterize teachers at predominantly black, white, and Hispanic high schools. An economic framework is also presented for understanding the nature of the teacher morale, exit, and absenteeism phenomena in urban schools.  相似文献   

Role of the Undergraduate Student Research Assistant in the New Millennium   总被引：1，自引：0，他引：1  

Thais Dutra Nascimento Silva  Lúcia Cristina da Cunha Aguiar  Jaqueline Leta  Dilvani Oliveira Santos  Fernanda Serpa Cardoso  Lúcio Mendes Cabral  Carlos Rangel Rodrigues    Helena Carla Castro 《CBE life sciences education》2004,3(4):235-240

In this study, we analyze the contribution of the undergraduate student who participates in the process of generating scientific data and developing a research project using Brazilian research as an example. Historically, undergraduate students have performed the critical role of research assistants in developing countries. This aspect has been underappreciated as a means of generating scientific data in Brazilian research facilities. Brazilian educational institutions are facing major age-related generational changes among the science faculty within the next 5–10 yr. A lack of adequate support for graduate students leads to a concern that undergraduates will not be interested in choosing research assistant programs and, subsequently, academic research careers. To remedy this situation it is important to focus on ways to encourage new research careers and enhance university–industry collaborations.  相似文献   

The Rôle of Tape and Record in Music Teaching     

Prof. Bruno Prowaznik 《Educational Media International》2013,50(3-4):49-50

Owing to the acoustic dimension of music the technical media used in music teaching which serve to store and reproduce sounds, namely tapes and records, are of particular significance. Differences between tape and record in the quality of sound reproduction are few, and are primarily due to the type of tape-recorder and gramophone used. The preparation for sound reproduction must not take too much time and this argument favours the use of the record. But the fact that the musical examples needed for one teaching unit usually have to be collected from a great number of records, which is cumbersome and time-consuming, seems to recommend a combined system as the best solution. The production of efficient teaching aids for music in the form of tapes and records ought to be improved. Commercial firms produce records of musical examples; others produce educational records containing musical examples as well as spoken explanations. There are other records sampling musical quotations for a certain field of study.  相似文献   

“Fácilis descensus Averni” Mind,Brain, Education,and Ethics: Highway to Hell,Stairway to Heaven,or Passing Dead End?*     

Bruno della Chiesa 《Mind, Brain, and Education》2010,4(2):45-48

Are human beings born unequal when it comes to ethics? Or are ethical standards acquired? Or both nature and nurture? Neuroscience is on its way to discovering biological underpinnings of ethics in our brains. Whatever the upcoming findings on this front will be, our philosophical, political, and educational views, and even the way we look at ourselves as a species, could soon be radically challenged, if not altered. AENEIS, the special section of this journal dedicated to Educational Neuroscience and Ethics, seeks to shed light on the crucial and sometimes frightening questions and answers we are to be confronted with. Starting with Charles Lang (“Science, Education, and the Ideology of ‘How”’) and Zachary Stein (“On the Difference Between Designing Children and Raising Them: Ethics and the Use of Educationally Oriented Biotechnology”), we are embarking on a fascinating but dangerous learning journey. To navigate between Scylla and Charybdis, extreme caution is highly recommended.  相似文献   

Metrological definition and evaluation of some mechanical properties of post-medieval Neapolitan yellow tuff masonry     

Bruno Calderoni  Giuseppe Cecere  Emilia Angela Cordasco  Luigi Guerriero  Pietro Lenza  Gaetano Manfredi 《Journal of Cultural Heritage》2010,11(2):163-171

The knowledge of the morphological and mechanical properties of masonry walls is very important for the refurbishment of ancient buildings, particularly when the requirements of both structural safety and historical preservation must be fulfilled. The masonry is not of homogenous material: its mechanical properties depend on stones, mortar, and texture which are very variable due to their dependence on the historical periods and the geographical area of the erection. For this reason, a deep knowledge of masonries built in different sites and historical periods is essential in order to evaluate both the capacities of bearing vertical load and the seismic vulnerability of the masonry structure. Three fundamental typologies of tuff masonry have been defined: they are the characteristics of different historical periods from the XVI to the XX century. The models are in full-scale in order to reproduce the three defined chronotypes. Original tuff stones quarried in the corresponding historical period, mortars similar to the original ones, reproduced according to ancient documents and original constructive techniques have been used for the construction of the specimens. Compression tests performed in displacement control have been carried out on the masonry models in order to determine the maximum resistance of the material and the corresponding strain, the ultimate strain and corresponding residual strength. In this paper, the procedure used for making the specimens and for experimentally evaluating the mechanical properties of post-medieval Neapolitan yellow tuff masonry are illustrated and the obtained results, even in terms of plastic capacity of these kinds of masonry, are reported.  相似文献   

Organizing links with science: Cooperate or contract?: A project-level analysis     

Bruno Cassiman  Maria Chiara Di Guardo  Giovanni Valentini 《Research Policy》2010,39(7):882-892

Links with science have been argued to improve the (innovation) performance of firms. Yet we still know comparatively little about the project-level characteristics affecting the organization of such links. Our study, based on a sample of 52 projects carried out by a multinational company in the semiconductor industry, reveals that the knowledge attributes of a project help in predicting how the R&D activities will be organized. In particular, basic projects are likely to be developed through formal cooperative agreements with universities. Such projects also tend to be strategically less important. For strategically more important projects, in contrast, and for those where the knowledge to be developed is particularly novel to the firm, the firm is more likely to resort to formal contracting with a university for a specific component of the R&D project, usually early on in the project.  相似文献   

School mapping restructure in rural China: achievements, problems and implications     

Dan Zhao  Bruno Parolin 《Asia Pacific Education Review》2012,13(4):713-726

This study considers the experience of school mapping restructure (SMR) in areas of rural China. It aims to understand what happened after SMR implementation. Through a combination of instruments such as questionnaires, interviews and document analysis, the study finds that SMR has impacted positively on the development of education in terms of generating scaling benefits, improved school conditions and educational quality, and more equitable distribution of educational resources. However, there remain several associated problems including longer schooling commute, household financial restrictions and student pressures, and increased teacher work-loads. The study recommends that more structured plans should be developed. Increased stakeholder participation should be enabled, and by providing increased teaching resources to rural schools, implementation should be improved.  相似文献   

The Organisation of Marathons in Divided Cities: Brussels,Belfast, Beirut and Jerusalem     

Bruno Coppieters 《国际体育史杂志》2013,30(11):1553-1576

The organisers of city marathons want to involve a large number of participants and to mobilise the support of local neighbourhoods. This is a particularly difficult challenge in a divided city, especially when the route crosses dividing lines in disputed territories – in which case, organising a marathon carries the risk of generating fresh conflict. But it is possible to avoid such an outcome. Brussels, where the dispute about the city boundaries has always been a peaceful one, has a city marathon that crosses these boundaries, and Belfast, a city with a long history of intercommunal violence, has successfully organised a marathon every year since 1982. Despite the segregation of Beirut's neighbourhoods, the participants in its marathon have run through the whole city since 2003. In Jerusalem, by contrast, a political row over the route of the first marathon in 2011 broke out in the municipal council long before the starter pistol was fired. To examine the reasons for these different outcomes, this article looks at the different types of territorial division in these cities, the types of relationship developed between the marathon organisers and the authorities, and the values the organisers have chosen to promote.  相似文献
