The last step of the Information Retrieval process is to display the found documents to the user. However, some difficulties might occur at that point. English texts are usually written in the ASCII standard. Unlike the English language, many languages have different character sets, and do not have one standard. This plurality of standards causes problems, especially in a web environment, where one may download a document with an unknown standard. This paper suggests a purely automatic way of finding the standard which was used by the document writer based on the statistical letters distribution in the language. We developed a vector-space-based method that creates frequencies vectors for each letter of the language and then matches a new document's vectors to the pre-computed templates. The algorithm was applied on various types of corpora in Hebrew, Russian and English, and provides an efficient solution to the stated problem in most cases. 相似文献

Taking notes is of uttermost importance in academic and commercial use and success. Different techniques for note-taking utilise different cognitive processes and strategies. This experimental study examined ways to enhance cognitive performance via different note-taking techniques. By comparing performances of traditional, linear style note-taking with alternative non-linear technique, we aimed to examine the efficiency and importance of different ways of taking notes. Twenty-six volunteer adult learners from an information management course participated in this study. Cognitive performance scores from a traditional linear note-taking group were compared with another group by using a commercially available non-linear note-taking technique. Both groups were tested in two settings: after a classroom lecture and a panel forum discussion. Tasks included measures on story comprehension, memory, complexity of mental representations and metacognitive skills. Data analysis revealed that the non-linear note-takers were significantly better than the linear group both in terms of the quantity and the quality of the learned material. This study demonstrates the importance of using cognitively compatible note-taking techniques. It identifies the cognitive mechanisms behind effective note-taking and knowledge representation. Using such techniques enables deeper understanding and more integrated knowledge management. 相似文献

Cultural expectations and sex-role standards about reading in Canada, Denmark, England, Finland, Israel, Japan, and U.S.A. were investigated. A picture test showing various activities and objects including reading and books was administered in each country to six sub-samples that approximated to the levels: students in grades I, IV, VIII, and XII, college students, and adults. Subjects had to ascribe the activity or object as being appropriate for either a boy or a girl. The results were consistent with the hypothesis that cultural expectations and sex-role standards about reading are congruent within one country but that they differ between countries. In particular, boys in Canada and the U.S.A. rapidly learn to perceive reading as a feminine activity, whereas Danish and Japanese males at all ages consistently view reading as acceptable masculine behaviour. 相似文献

The Anne Frank Haven: A case of an alternative educational program in an integrative Kibbutz setting
Miriam Ben-Peretz Moshe Giladi Yuval Dror 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》1992,38(1):47-63
The essential features of the programme of the Anne Frank Haven are the complete integration of children from low SES and different cultural backgrounds with Kibbutz children; a holistic approach to education; and the involvement of the whole community in an open residential school. After 33 years, it is argued that the experiment has proved successful in absorbing city-born youth in the Kibbutz, enabling at-risk populations to reach significant academic achievements, and ensuring their continued participation in the dominant culture. The basic integration model consists of layers of concentric circles, in dynamic interaction. The innermost circle is the class, the learning community. The Kibbutz community and the foster parents form a supportive, enveloping circle, which enables students to become part of the outer community and to intervene in it. A kind of meta-environment, the inter-Kibbutz partnership and the Israeli educational system, influence the program through decision making and guidance. Some of the principles of the Haven — integration, community involvement, a year's induction for all new students, and open residential settings — could be useful for cultures and societies outside the Kibbutz. The real secret of success of an alternative educational program is the dedicated, motivated and highly trained staff.
Zusammenfassung Die Hauptpunkte des Programms des Anne-Frank-Internats sind die vollständige Integration von Kindern aus sozial schwachen Familien und unterschiedlichem kulturellen Hintergrund in die Gruppe von Kibbutz-Kindern, ein holistischer Ansatz zur Erziehung und die Beteiligung der gesamten Gemeinde an einer offenen Heimschule. Das Experiment wird von den Autoren 33 Jahre nach Beginn als erfolgreich angesehen, sowohl bei der Integration der Stadtjugend in den Kibbutz und den eröffneten Möglichkeiten für Risikogruppen, bedeutende akademische Leistungen zu vollbringen, als auch bei deren gesicherter kontinuierlicher Beteiligung an einer dominanten Kultur. Das Grundintegrationsmodell besteht aus Schichten konzentrischer Kreise in dynamischer Interaktion. Der innerste Kreis ist die Klasse, die Lerngemeinschaft. Die Kibbutz-Gesellschaft und die Pflegeeltern bilden einen unterstützenden und beschützenden Kreis, der es den Schülern ermöglicht, Teil der äußeren Gemeinde zu werden und sich dort zu engagieren. Eine Art Meta-Umgebung, die Partnerschaft zwischen den Kibbutzim und das israelische Schulsystem beeinflussen das Programm, indem Entscheidungen getroffen und Richtlinien gegeben werden. Einige der Prinzipien des Internats wie Integration, Beteiligung der Gemeinden, einjährige Einführungszeit für alle neuen Schüler und offene Wohnbedingungen, könnten für Kulturen und Gesellschaften außerhalb des Kibbutz ebenfalls von Interesse sein. Das wahre Geheimnis des Erfolgs eines alternativen Schulprogramms ist jedoch engagiertes, motiviertes und hochqualifiziertes Personal.
Résumé L'insertion complète des enfants de bas statut socio-économique et de milieux culturels différents aux enfants des kibboutz, une approche holistique de l'enseignement et la participation de l'ensemble de la communauté à une école résidentielle ouverte constituent les caractéristiques essentielles du programme Anne Frank Haven. On est d'avis, 33 ans plus tard, que cette expérience a réussi à intégrer les jeunes citadins dans les kibboutz, à donner un niveau de scolarité satisfaisant aux populations à risque et à assurer leur participation continue à la culture dominante. Le modèle d'intégration de base est constitué de couches de cercles concentriques en interaction dynamique. Le cercle le plus au centre représente la classe, la communauté qui apprend. La collectivité du kibboutz et les parents nourriciers forment un cercle de soutien enveloppant qui permet aux élèves de prendre part à la vie de la communauté extérieure et d'intervenir au sein de celle-ci. Une sorte de méta-environnement, l'association entre les kibboutz et le système éducatif israélien exercent une influence sur le programme par leurs décisions et les conseils qu'ils prodiguent. Quelques-uns des principes du programme Haven, tels que l'intégration, la participation de la communauté, une année d'initiation pour tous les nouveaux élèves et les structures d'internat ouvert, pourraient servir aux cultures et sociétés à l'extérieur des kibboutz. Le véritable secret du succès d'un programme éducatif non conventionnel repose sur un personnel dévoué, motivé et parfaitement formé.相似文献

The cost of health and safety (H&S) failures to the UK industry is currently estimated at up to £6.5 billion per annum, with the construction sector suffering unacceptably high levels of work-related incidents. Better H&S education across all skill levels in the industry is seen as an integral part of any solution. Traditional lecture-based courses often fail to recreate the dynamic realities of managing H&S on site and therefore do not sufficiently create deeper cognitive learning (which results in remembering and using what was learned). The use of videos is a move forward, but passively observing a video is not cognitively engaging and challenging, and therefore learning is not as effective as it can be. This paper describes the development of an interactive video in which learners take an active role. While observing the video, they are required to engage, participate, respond and be actively involved. The potential for this approach to be used in conjunction with more traditional approaches to H&S was explored using a group of 2nd-year undergraduate civil engineering students. The formative results suggested that the learning experience could be enhanced using interactive videos. Nevertheless, most of the learners believed that a blended approach would be most effective. 相似文献

Spatial ability has been found to be a good predictor of success in learning anatomy. However, little research has explored whether spatial ability can be improved through anatomy education and experience. This study had two aims: (1) to determine if spatial ability is a learned or inherent facet in learning anatomy and (2) to ascertain if there is any difference in spatial ability between experts and novices in anatomy. Fifty participants were identified: 10 controls, 10 novices, 10 intermediates, and 20 experts. Participants completed four computerized spatial ability tasks, a visual mental rotation task, categorical spatial judgment task, metric spatial task, and an image-scanning task. The findings revealed that experts (P = 0.007) and intermediates (P = 0.016) were better in the metric spatial task than novices in terms of making more correct spatial judgments. Experts (P = 0.033), intermediates (P = 0.003), and novices (P = 0.004) were better in the categorical spatial task than controls in terms of speed of responses. These results suggest that certain spatial cognitive abilities are especially important and characteristic of work needed in clinical anatomy, and that education and experience contribute to further development of these abilities. 相似文献

Why do some countries appear more popular than others in mass media? Although researchers have long sought to explain foreign countries’ prevalence in the media, to date they have exclusively focused on news, leaving other types of media content unexplored. In addition, focusing on media effects and media content, the literature on entertainment and politics has largely ignored the study of agenda-building processes. Thus, this study fills these gaps by exploring factors affecting the volume of references to foreign countries in both U.S. news and entertainment media. Analyzing more than 400 U.S. television shows, four news channels, and two newspapers spanning from 2000 to 2011, we reexamine past findings on salience of foreign countries in the news and apply these findings to a new field of research, entertainment media. We further suggest that the same factors shaping foreign countries’ prevalence in the news media are applicable to both news and entertainment and that in the context of foreign countries’ prevalence, the criteria for “newsworthiness” and “fictionworthiness” is similar. 相似文献

This article explores the relationship between philanthropy and education in the context of eighteenth‐century Protestant Dissent. More particularly, it examines the intersection between philanthropy, fund‐raising and educational administration as they evolved within the institutional lifecycle of the collegiate Dissenting academies. It argues that individual academies experienced at least three of four life stages, each of which had its own unique challenges. All academies went through the first two of these stages, namely ‘foundation’ and ‘maintenance’. Whether or not an academy experienced the last two stages – ‘transition’ and ‘dissolution’ – depended on factors such as the financial strength of an academy and the reliability of its principal supporters. To illustrate these stages and their philanthropic subtexts, the article focuses on three institutional ‘traditions’, those of the Northampton Academy and its successors, the Warrington Academy, and Trevecca College and its successor Cheshunt College. 相似文献
