Explaining Individual Differences in Trajectories of Simultaneous Bilingual Development: Contributions of Child and Environmental Factors

Effects of child and environmental factors in moderating the course of bilingual development were investigated using longitudinal data, from age 2.5 to 5 years, on 126 U.S.-born children with early exposure to Spanish and English. Multilevel models of Spanish and English expressive vocabulary identified children’s phonological memory ability as a significant predictor of both outcomes, while also replicating the effect of the relative amount of language exposure. In addition, nonverbal IQ was a significant predictor of English vocabulary; birth order and maternal education in Spanish were significant predictors of Spanish vocabulary. These findings expand our understanding of the sources of the wide heterogeneity in bilingual development and of the requirements that language acquisition makes of learners and their environments.     

Incorporating a new bioinformatics component into genetics at a historically black college: outcomes and lessons

Many students at minority-serving institutions are underexposed to Internet resources such as the human genome project, PubMed, NCBI databases, and other Web-based technologies because of a lack of financial resources. To change this, we designed and implemented a new bioinformatics component to supplement the undergraduate Genetics course at Clark Atlanta University. The outcomes of the Bioinformatics course were assessed. During the first week of the semester, students were assigned the Felder-Soloman's Index of Learning Styles Inventory. The overwhelming majority of students were visual (82.1%) and sequential (75.0%) learners. Furthermore, pre- and postcourse surveys were administered during the first and the last week of the course to assess learning, confidence level, and mental activity. These indicated students increased the number of hours spent using computers and doing homework. Students reported confidence in using computers to study genetics increased, enabling them to better visualize and understand genetics. Furthermore, students were more mentally engaged in a more social learning environment. Although the students appreciated the value of the bioinformatics component, they reported the additional work load was substantial enough to receive additional course credit.     

<Emphasis Type="Italic">Bologna reloaded</Emphasis> – Wo müssen wir nachladen?

Nach fast 10 Jahren Umsetzungserfahrung an vielen österreichischen Universitäten zeigen sich die Vorteile und Herausforderungen aber auch die Hürden und Tücken des Bologna-Systems. Dieser Beitrag soll – aus der Erfahrung des Vizerektorats für Lehre und Internationales – die meist diskutierten Punkte aufzeigen und näher beleuchten.     

Impelling research productivity and impact through collaboration: a scientometric case study of knowledge management

A case study for impelling university research productivity and impact through collaboration is presented. Scientometric results support the hypothesis that a knowledge management model increased research collaboration and thereby boosted a university’s number of publications and citations. Results come from fifteen years of data at a Mexican university with 2400 researchers who produced 24,000 works in fifteen research disciplines. These data are treated with social network visualizations and algorithms to identify patterns of collaboration and clustering, as well as with normalizations to make disciplines comparable and to verify increasing citation impact. The knowledge management model implemented in the study may be a cost-effective way for universities to intensify collaboration and improve research performance.     

A Matter of Language or Culture: Coverage of the 2004 U.S. Elections on Spanish- and English-Language Television

This article fills a gap in the communication and political science literature by comparing how Spanish- and English-language television stations cover U.S. elections. A content analysis of more than 400 national network news stories and nearly 3,000 local news stories reveals that local and network Spanish-language stations provide less election coverage than their English-language counterparts. Although Spanish-language stations are more likely to focus election coverage on “Latino” issues or interests, the results indicate only moderate differences in how stations in each language frame their election stories, with stations in both languages concentrating more coverage around campaign strategy and the horse race than substantive issues.     

Properties of dual language exposure that influence 2-year-olds' bilingual proficiency

The mothers of 29 Spanish English bilingual 25-month-olds kept diary records of their children's dual language exposure and provided information on their children's English and Spanish language development using the MacArthur-Bates inventories. Relative amount of exposure predicted language outcomes in English and Spanish. In addition, the number of different speakers from whom the children heard English and the percent of their English input that was provided by native speakers were unique sources of variance in children's English skills. These properties of children's dual language exposure and their bilingual proficiency varied as a function of whether the children's mother, father, or both parents were native Spanish speakers. Practical and theoretical implications are discussed.     

Challenges in Argumentation and Paraphrasing Among Beginning Students in Educational Sciences

The present study aimed to identify difficulties in writing at the beginning of educational science programmes in the Finnish Open University by analysing the students’ written argumentation and use of sources at the textual level. The data were analysed using qualitative content analysis. The results showed that many students began their educational studies with weak writing competencies. While many of the problems were directly related to students’ failure to explain the ideas in their sources in their own words, some problems pertained to other aspects, such as the inability to construct convincing arguments. Understanding the nature of the problems in writing encountered by beginning students in educational sciences can help teachers foster students’ participation in academic discourse.
