Children with reading problems were exposed either to a self-paced computer programme that focused on improving phonetic ability, or underwent a classroom-based reading intervention. Exposure was limited to 3 40-min sessions a week, for six weeks. The children were assessed in terms of their reading, spelling, and mathematics abilities, as well as for their externalising and internalising behaviour problems, before the programme commenced, and immediately after the programme terminated. Relative to the control group, the computer-programme improved reading by about seven months in boys (but not in girls), but had no impact on either spelling or mathematics. Children on the programme also demonstrated fewer externalising and internalising behaviour problems than the control group. The results suggest that brief exposure to a self-paced phonetic computer-teaching programme had some benefits for the sample.

Methods: Four databases (PubMed, Embase, Web of Science, and Base de Donnees de Sante Publique) were searched with cross-references from published reviews. We included recent studies, original epidemiological studies for which the association was assessed with blind reviewing with control group. Relevant associations were extracted, and a metarisk was calculated using the generic variance approach (meta--odds ratio [meta-OR]). Results: Six studies met the criteria for inclusion. Results are contradictory because of heterogeneous work exposure. The meta-OR for computer use was 1.67 (95% confidence interval [CI], 0.79 to 3.55). The meta-OR for keyboarding was 1.11 (95% CI, 0.62 to 1.98) and for mouse 1.94 (95% CI, 0.90 to 4.21). Conclusion: It was not possible to show an association between computer use and CTS, although some particular work circumstances may be associated with CTS.

The authors measured electromagnetic fields (EMFs) laptop computers produce and estimated the induced currents in the body, to assess the safety of laptop computers. The authors evaluated 5 commonly used laptop of different brands. They measured EMF exposure produced and, using validated computerized models, the authors exploited the data of one of the laptop computers (LTCs) to estimate the magnetic flux exposure of the user and of the fetus in the womb, when the laptop is used at close contact with the woman's womb. In the LTCs analyzed, EMF values (range 1.86 T) are within International Commission on Non-Ionizing Radiation (NIR) Protection (ICNIRP) guidelines, but are considerably higher than the values recommended by 2 recent guidelines for computer monitors magnetic field emissions, MPR II (Swedish Board for Technical Accreditation) and TCO (Swedish Confederation of Professional Employees), and those considered risky for tumor development. When close to the body, the laptop induces currents that are within 34.2% to 49.8% ICNIRP recommendations, but not negligible, to the adult's body and to the fetus (in pregnant women). On the contrary, the power supply induces strong intracorporal electric current densities in the fetus and in the adult subject, which are respectively 182263% and 71483% higher than ICNIRP 98 basic restriction recommended to prevent adverse health effects. Laptop is paradoxically an improper site for the use of a LTC, which consequently should be renamed to not induce customers towards an improper use.

With the advent of mobile devices, users can interact with Social Media platforms anytime/anywhere, increasing the proportion of geo-located Social Media interactions and opening new doors to localized insights. This article suggests a new method built upon the industry standard Recency, Frequency and Monetary model to quantify the impact of a topic on a defined geographical location during a given period of time. We model each component with a set of metrics analyzing how users in the location actively engage with the topic and how they are exposed to the interactions in their Social Media network related to the topic. Our method implements a full fledged information extraction system consuming geo-localized Social Media interactions and generating on a regular basis the impact quantification metrics. To validate our approach, we analyze its performance in two real-world cases using geo-located tweets.

The current paper reports the results of two studies, a repeated exposure study and a single exposure study, which examine habituation and generalization of biophysiological and self-reported arousal responses to violent video games. The findings indicate that repeated play leads to habituation in both biophysiological and self-report responses. Notably, evidence of generalization is more apparent in the biophysiological data. The results are discussed in terms of: (1) implications for game developers and players, (2) implications for game researchers, (3) current conceptual ambiguity between cross-sectional and longitudinal models, and (4) the appropriateness of utilizing self-report measures in longitudinal studies examining arousal.

The results show that frequent SNS use may entail higher chances of interacting with heterogeneous others, but the influence is only indirectly exerted through its effects on two news sharing activities. Findings also indicate that political interest and news sharing activities interact with each other in predicting the degree of network heterogeneity. The study is conducted with a nationally representative survey.

Two aspects of user interactions are examined: the interconnectedness of users as an indication for users' networks of exchange of opinions and information, andexposureto a political diversity of information sources. Findings suggest that users prefer exposing themselves to politically like-minded information sources. Furthermore, television hosts failed to evoke an exchange of opinions and ideas among their followers. In contrast, other information sources that reported about these hosts evoked denser interaction among their followers.
