Reading habits of pre-service teachers / Trayectorias de lectura del profesorado en formación

Abstract

Recent studies on the reading habits of those studying to be teachers have questioned the reading identity of the people who are to become the future mediators of reading in school environments. Within this framework, the current research constitutes an exploratory hermeneutic interpretative study on the reading habits of pre-service teachers, in order to establish a reader profile for this population group, which is the focus of our study. The information is taken from students at Universidad Autónoma de Barcelona. It has been collected through sharing life experiences and has undergone a mixed content statistical analysis. The results reveal a standard profile defined by discontinuous reading habits, precarious intertexts and current practices mainly related to bestsellers.     

Language Arts Performance Assignments: Generalizability Studies of Local and Central Ratings

We conducted generalizability studies to examine the extent to which ratings of language arts performance assignments, administered in a large, diverse, urban district to students in second through ninth grades, result in reliable and precise estimates of true student performance. The results highlight three important points when considering the use of performance assessments in large-scale settings: (a) Rater training may significantly impact reliability; (b) simple rater agreement indices do not provide enough information to assess the reliability of inferences about true student achievement; and (c) assessments adequate for relative judgments of student performance do not necessarily provide sufficient precision for absolute criterion-referenced decisions.     

Association of leisure time and occupational physical activity with obesity and cardiovascular risk factors in Chile

ABSTRACT

The aim of this study was to investigate the association between physical activity (PA), both occupational (OPA) and during leisure time (LTPA), with obesity and cardiovascular risk factors in Chilean adults. 5,157 participants from the Chilean National Health Survey 2009–2010 were included in this study. OPA and LTPA levels were assessed using the Global Physical Activity Questionnaire. The association between both PA with obesity and cardiovascular risk factors was determined using logistic regression. Our findings showed a significant trend between higher LTPA and lower odds for obesity (OR 0.64 [95% CI: 0.53; 0.76], central obesity 0.52 [0.44; 0.61]) and other cardiovascular risk factors including diabetes (OR: 0.72 [0.55; 0.94]), hypertension (OR: 0.59 [0.50; 0.71]) and metabolic syndrome (OR: 0.62 [0.50; 0.78]). In contrast, OPA was only associated with lower odds of diabetes (OR: 0.79 [0.65; 0.98]) and hypertension (0.85 [0.74; 0.98]). In conclusion, LTPA was associated with a lower risk of all major cardiovascular risk factors, whereas OPA was only associated with a lower risk of diabetes and hypertension.

Using institutional theory and dynamic simulation to understand complex e-Government phenomena

Governments around the world have developed e-Government programs expecting to obtain important benefits such as improved efficiency or greater transparency. However, many e-Government projects fail to deliver their promises in terms of specific outcomes. Some of such failures are the result of a lack of understanding about the relationships among technologies, information use, organizational factors, institutional arrangements, and socio-economic contexts involved in the selection, implementation, and use of information and communication technologies (ICT), producing mismatches and unintended consequences. This paper proposes the use of institutional theory and dynamic simulation, particularly system dynamics, as an integrated and comprehensive approach to understand e-Government phenomena. Combining a sound theory and a sophisticated analytical technique will help to improve our understanding about ICT in government settings. The paper draws on the case of the e-Mexico program, particularly on the strategy to create web-based content portals for citizens in the areas of education, health, economy, and government. Using the same technological infrastructure and under the leadership of the same Federal Ministry, four different networks of government and non-government organizations engaged in the creation of internet portals and their content. The results provide evidence to demonstrate important bidirectional relationships between formal processes (institutions), agency networks (organizational forms), and the resulting characteristics of the four thematic portals (enacted technology).     

Influence of leg preference on bilateral muscle activation during cycling

The purpose of this study was to investigate asymmetry of muscle activation in participants with different levels of experience and performance with cycling. Two separate experiments were conducted, one with nine cyclists and one with nine non-cyclists. The experiments involved incremental maximal and sub-maximal constant load cycling tests. Bilateral surface electromyography (EMG) and gross and net muscle efficiency were assessed. Analyses of variance in mixed linear models and t-tests were conducted. The cyclists in Experiment 1 presented higher gross efficiency (P < 0.05), whereas net efficiency did not differ between the two experiments (21.3 ± 1.4% and 19.8 ± 1.0% for cyclists and non-cyclists, respectively). The electrical muscle activity increased significantly with exercise intensity regardless of leg preference in both experiments. The coefficient of variation of EMG indicated main effects of leg in both experiments. The non-preferred leg of non-cyclists (Experiment 2) presented statistically higher variability of muscle activity in the gastrocnemius medialis and vastus lateralis. Our findings suggest similar electrical muscle activity between legs in both cyclists and non-cyclists regardless of exercise intensity. However, EMG variability was asymmetric and appears to be strongly influenced by exercise intensity for cyclists and non-cyclists, especially during sub-maximal intensity. Neural factors per se do not seem to fully explain previous reports of pedalling asymmetries.     

Scale of attitudes of schoolchildren towards immigrant pupils

In the academic year 2004–2005, approximately 400,000 immigrant pupils were enrolled in Spanish schools and six-form colleges. The racial and ethnic diversity that Spanish society and schools present could be a source of new opportunities and social enrichment, for the national as well as the immigrant population. However, this contact between nationals and immigrants is not free of problems. School is one of the areas where attitudes towards different social groups begin to be formed, while at the same time being the main opportunity that our society has to create an environment of coexistence and attitudinal change. The first step to look at such a complex phenomenon in more detail is to have evaluation tools available that allow us to measure it. In this article we present the results referring to psychometric features, and we carry out a differential analysis of the Scale of attitudes of school-children towards immigrant pupils.     

Why Does Infant Stepping Disappear and Can It Be Stimulated by Optic Flow?

Two independent experiments (n = 22 and n = 22) showed that 2‐month‐old infants displayed significantly more stepping movements when supported upright in the air than when supported with their feet contacting a surface. Air‐ and surface‐stepping kinematics were quite similar (Experiment 2). In addition, when data were collapsed across both experiments, more air steps and more donkey kicks were seen when infants were exposed to optic flows that specified backward compared to forward translation. The findings challenge the currently accepted heavy legs explanation for the disappearance of stepping at 2 months of age and raise new questions about the visual control of stepping.
