Reading with meaning: the contributions of meaning-related variables at the word and subword levels to early Chinese reading comprehension

This study examined the associations of three levels of meaning acquisition, i.e., whole word (vocabulary), morpheme (morphological awareness), and semantic radical (orthography-semantic awareness) to early Chinese reading comprehension among 164 Hong Kong Chinese primary school students, ages 7 and 8?years old, across 1?year. With time 1 word reading, phonological awareness and speeded naming controlled, morphological awareness was uniquely associated with concurrent and subsequent reading comprehension; orthography-semantic awareness uniquely explained concurrent reading comprehension at time 2. Together, the meaning acquisition variables explained between 2 and 6% unique variance in reading comprehension across time, underscoring the importance of acquisition of meaning for early reading comprehension among Chinese children.     

Outdoor education gives fewer demands for action regulation and an increased variability of affordances

In children's lives there are a lot of instigators for actions in every milieu and situation. When children grow older, the cortical activity starts to regulate the action instigation from the limbic system. The school system makes demands of action regulation for children. In outdoor education the many instigators for actions are not under the same demands for regulation as inside the classroom. In this study we have interviewed nine children about their experience with outdoor education. The interviews shows a wide variability of affordances grasped from outdoor education, as well as a tendency toward gender differences in what kind of action possibilities they grasp. These activities give the children useful experiences that are directly and indirectly relevant for their curriculum.     

Couples’ communication problems: The counselor's perspective

Marital and relational counselors bring their normative ideas about couples’ communication to the therapeutic setting and these ideas become a part of the ongoing dialogue between counselors and their clients. Although many therapists emphasize couples’ communication problems as a source of relational difficulty, it is not clear how therapists conceive of, and explain, those problems. The current study addresses this issue by examining counselors’ perceptions of, and attributions for, couples’ communication problems. Interviews with 50 couples’ counselors suggest that communication problems are common among clients. The most frequently noted communication problems involved failing to take the other's perspective when listening, blaming the other for negative occurrences, and criticizing the other. Most of counselors’ attributions for couples’ communication problems referred to stable, unchanging causes and focused on external factors. A content analysis of the attributions further indicated that many counselors felt communication problems were the result of patterns taught to individuals by their family of origin. Finally, when asked to identify the most central problem for dissatisfied partners, only about one‐fourth of the counselors cited issues directly related to communication. The majority noted that communication was usually a manifestation of other, more fundamental, difficulties. Taken together, the findings indicate that counselors tend to focus on individual, rather than interpersonal and relational factors when conceiving and treating the cause of communication problems.     

Gender differences in associations between exposure to school HIV education and protective sexual behaviors and sexually transmitted disease/HIV diagnosis among high school students

This study aimed to assess associations between school HIV education and protective sexual behaviors and sexually transmitted disease (STD)/HIV diagnosis with a representative sample of male and female high school students. Data from male and female adolescent participants in the 1999, 2001 and 2003 Massachusetts Youth Risk Behavior Survey (n = 12,243) were analyzed. Adjusted regression analyses stratified by gender were conducted to assess relationships between school HIV education exposure and the following outcomes: no sexual initiation, condom use at last sex, no multiple sex partners in the past three months and no history of STD/HIV diagnosis. Participants were mostly White (75%) and were 51% male; the subsample of sexually active students was younger than the total sample but was otherwise similar in demographics. School HIV education was reported by 93% of our sample and was significantly related to sexual initiation among boys (odds ratio = 1.9, 95% confidence interval = 1.4–2.7) but not girls. Among sexually experienced students (n = 4752), boys reporting exposure to school HIV education were significantly more likely to report condom use (odds ratio = 2.2, 95% confidence interval = 1.6–3.1), no multiple sex partners (odds ratio = 3.2, 95% confidence interval = 2.3–4.4) and no STD/HIV diagnosis (odds ratio = 3.2, 95% confidence interval = 2.0–5.0); girls reporting such exposure were significantly more likely to report no multiple sex partners (odds ratio = 2.2, 95% confidence interval = 1.3–3.6). In conclusion, exposure to school HIV education is associated with sexual protective behaviors and reduced likelihood of STD/HIV diagnosis for boys but less so for girls, suggesting the need for more gender‐tailored approaches to school HIV education.     

Defensive transition in soccer – are prompt possession regains a measure of success? A quantitative analysis of German Fußball-Bundesliga 2010/2011

Abstract

The aim of the study was to evaluate the time required by German Bundesliga soccer teams to recover ball possession – which was operationalised as defensive reaction time – and identify both the differences between top teams and the rest of the league and the influence of match status on the aforementioned indicator. Therefore, teams were classified into 3 distinct groups according to their final league position: top, in-between and bottom. In total, all 306 games of the season 2010/2011 were analysed post-event. Top teams recovered ball possession quickest after losing it in comparison to the other groups and demonstrated lower defensive reaction times (approximately 1 s in each match status) compared to the remaining teams. Moreover, all groups showed the lowest defensive reaction times when trailing. The results of this study imply that recovering ball possession as quickly as possible after losing possession was an important determinant of successful defensive performance in German Bundesliga season 2010/2011. Further, the current score seemed to be highly influential on the defensive reaction time. The implications of the results for future research, especially considering opponent interactions, are critically discussed.     

Diagnosis,Evaluation, and Treatment of Lead Poisoning in General Population

Among the heavy metals, lead still remains the major toxic pollutant of the environment. Human exposure to lead can occur through numerous pathways including air, food, dust, soil, and water. In the present study 14 lead poisoned patients with non-occupational lead exposure were evaluated. They were followed up and compared against the controls with no history of lead exposure. The patients had high blood lead levels and symptoms of weakness, dizziness, abdominal pain, generalized body ache, loss of appetite, and anxiety. Repeated course of chelation therapy helped to bring down their body burden of lead. Alternative sources for lead exposure can cause severe lead poisoning in general population. Screening and medical management of such individuals is very important to identify and eliminate sources of lead. The treatment and management requires a thorough medical evaluation and environmental intervention.
