A single-display groupware collaborative language laboratory

Language learning tools have evolved to take into consideration new teaching models of collaboration and communication. While second language acquisition tasks have been taken online, the traditional language laboratory has remained unchanged. By continuing to follow its original configuration based on individual work, the language laboratory fails to take advantage of the potential provided by collaborative learning. We propose the use of a language laboratory based on single-display groupware (SDG) for learning vocabulary, grammar, pronunciation, and listening comprehension. By adopting SDG, the language laboratory benefits from the advantages of small group collaborative learning. In this paper, we first describe the design and pedagogical merit of the SDG collaborative language laboratory. We then share the results of a quasi-experimental pre–post comparison study, and use an observation guideline to analyze whether the conditions for collaborative learning have been fulfilled. Based on the results of this study, we conclude that developing pronunciation skills can be more effective when using a collaborative language laboratory versus an individual language laboratory. In addition to this, it can also be concluded that collaborative learning is most effective when accompanied by adequate instructional design.     

Effects of marijuana use during pregnancy on newborn cry

The effects of maternal marijuana use on the newborn cry were studied in Jamaica, where it was possible to rule out confounding factors such as the use of other substances and demographic variables that have clouded previous studies and where higher dosages may make the effects more visible. The acoustic characteristics of the cries of 20 infants of marijuana users and 20 controls were analyzed. The cries of the infants of marijuana users were shorter, had a higher percentage of dysphonation, a higher and more variable fundamental frequency, and a lower first formant than controls. There was also a dose response relation between the first formant and marijuana use. We suggest that heavy marijuana use affects the neurophysiological integrity of the infant.     

The role of external experts’ intervention in higher education institutions for radical change

This paper focuses on the way lecturers observe, feel restrained by and cope with quality management systems that have been implemented in the higher education systems of the United Kingdom and the Netherlands. As two sides of the same coin, quality enhancement and quality control are of increased significance in European Higher Educaction Institutions (HEIs), particularly through the Bologna Process. We are interested in the way that both enhancement and control blend into the current systems, and we are concerned for too much dominance of control, as has been suggested in recent managerial literature. Analysis of 40 interviews in both countries among researchers and lecturers in traditional and universities of applied sciences showed many similarities. It is not so much the general idea of quality management that is being turned down by the respondents. They see the benefits quite clearly. Still, the general belief is that quality management in its current shape and character does not fit with the work of the individual academic, neither their teaching nor their research. The respondents worry for and resent the consequences of increased emphasis on quality assurance and control. The developments concerning the quality management of their HEIs are perceived in terms of quality assurance by the UK respondents. Instead, the Dutch are more occupied with finding ways to “how to deal with” such developments.

This article reports a national study of Internet users' usage of cable television Web site features to illustrate the dynamics of cross-media use in electronic media and explore the role of cable television network Web sites in network branding and viewership. Our findings indicate that younger Internet users are much more likely to use television Web sites than older Internet users. Despite the low use of the enhanced features of television Web sites, the increase in the number of Web site feature usage positively predicts viewer loyalty, subscriber loyalty, and to a lesser extent, new subscriber attraction for cable networks.     

Ball possession effectiveness in men's and women's elite basketball according to situational variables in different game periods

Abstract

The aim of the present study was to identify the importance of basketball performance indicators in predicting the effectiveness of ball possessions in men's and women's basketball, when controlling for situational variables and game periods. The sample consisted of 7234 ball possessions, corresponding to 40 games from the Spanish professional leagues. The effects of the predictor variables on successful ball possessions according to game period were analysed using binary logistic regressions. Results from men's teams show interactions with number of passes and ending player during the first five minutes, with starting and ending zone, defensive systems, screens used and possession duration during the middle thirty minutes, and there were interactions with passes used, possession duration and players involved during the last five minutes. Results from women's teams show interactions with starting and ending zone, passes used, defensive systems and ending player during the first five minutes, and with starting and ending zone, and screens used during the middle thirty minutes. The results show no interaction with situational variables in men's basketball, while league stage was important during the middle thirty minutes and last five minutes in women's basketball, whereas match status was only important during the last five minutes.     

Performance analysis of elite men’s and women’s wheelchair basketball teams

Abstract

The purpose of the present study was to identify which game-related statistics discriminate winning and losing teams in men’s and women’s elite wheelchair basketball. The sample comprised all the games played during the Beijing Paralympics 2008 and the World Wheelchair Basketball Championship 2010. The game-related statistics from the official box scores were gathered and data were analysed in 2 groups: balanced games (final score differences ≤12 points) and unbalanced games (final score differences >13 points). Discriminant analysis allowed identifying the successful 2-point field-goals and free-throws, the unsuccessful 3-point field-goals and free-throws, the assists and fouls received as discriminant statistics between winning and losing teams in men’s balanced games. In women’s games, the teams were discriminated only by the successful 2-point field-goals. Linear regression analysis showed that the quality of opposition had great effects in final point differential. The field-goals percentage and free-throws rate were the most important factors in men’s games, and field-goals percentage and offensive rebounding percentage in women’s games. The identified trends allow improving game understanding and helping wheelchair basketball coaches to plan accurate practice sessions and, ultimately, deciding better in competition.     

Intrinsic Motivation and Environmental Factors Affecting Research of Social Work Faculty on Aging

Within the context of Self-determination Theory, this research identifies intrinsic motivation and environmental factors that support social-work-faculty research in aging. Intrinsic factors include faculty's interest in gerontology as a field of practice, the desire to advance knowledge in the field of gerontology, including producing publications that disseminate information about their research, and the desire to make tenure and/or to advance their careers. Environmental factors include institutional supports such as release time to do research, reduced teaching loads, summer research support. Also included are mentoring relationships that complement the faculty's intrinsic motivation and create an environment supportive of research, grant writing, and publishing. Faculty motivation to work in the field of gerontology and institutional support for gerontological research are critical to sustain and expand the capacity of social work faculty to advance science in gerontology research. Such motivation is also needed to create vibrant academic environments that attract students at all levels into the field of gerontology, a field experiencing a rapidly expanding gap between service need and workforce capacity of social-work-faculty research in aging.     

How teaching world religions brought a truce to the culture wars in Modesto,California

Despite a growing consensus among scholars and activists about the importance of religion, proposals for teaching about it have often been a source of division rather than unity in American public school districts. Faced with familiar cultural conflicts, Modesto, California, chose to become the first public school district in the USA to require all high school students to take an extended and independent course in world religions. The results of the first, large‐scale empirical research on the effects of teaching about religion in USA public schools provides evidence that Modesto’s bold approach was worth the risk. Surveys and interviews administered to students show statistically significant increases in students’ knowledge about other religions, and levels of passive tolerance – willingness to refrain from discrimination – and active tolerance – willingness to act to counter discrimination. The course has not been the subject of lawsuits or complaints by parents and has gained acceptance among all of Modesto’s religious groups.
