The impact of a cooperative learning experience on pupils’ popularity,non‐cooperativeness,and interethnic bias in multiethnic elementary schools

In this study we investigated popularity and perceived non‐cooperativeness in multiethnic elementary schools. A sample of 94 pupils aged 10–12 years, from five multiethnic elementary schools, were divided into 26 teams and participated in a structured cooperative learning (SCL) curriculum of 11 lessons. Neither teachers nor pupils had prior SCL experience. The results show that SCL time increased popularity and decreased perceived non‐cooperativeness across ethnic backgrounds. In addition, experience with SCL enhanced the popularity of immigrant pupils and decreased differences in perceived non‐cooperativeness between immigrant and non‐immigrant pupils. Importantly, SCL time only raised popularity and decreased perceived non‐cooperativeness within ethnically heterogeneous teams. This last result extends the notion that enduring interethnic contact is fruitful for interethnic friendships.     

The sustainability of a teacher professional development programme for beginning urban teachers

This study investigated the long-term effects of a professional development intervention for beginning urban teachers and explored which characteristics and activities in school organisations contributed to the sustainability of these effects. A quasi-experimental study (n = 72) investigated whether the positive effects of the programme were observed one year after the programme ended. Interviews with teachers and principals (n = 19) were used to explore which characteristics and activities in schools contributed to those positive effects. A significant long-term effect of the programme was found on teachers’ competences and professional orientation. An open culture in the schools was experienced as an important factor for the sustainability of the programme’s effects.     

Influence of ACTN3 R577X polymorphism on ventilatory thresholds related to endurance performance

The purpose of this study was to verify the association between ACTN3 polymorphism and physiological parameters related to endurance performance. A total of 150 healthy male volunteers performed a maximal incremental running test to determine the speeds corresponding to ventilatory threshold (VT) and respiratory compensation point (RCP). Participants were genotyped and divided into terciles based on the analysed variables. Genotype frequencies were compared through χ² test between lower and higher terciles, with the lowest or highest values of each analysed variable. ACTN3 XX genotype was over-represented in higher tercile for VT and RCP. Odds ratio also showed significantly higher chances of XX individuals to be in higher tercile compared to RR (7.3) and RR + RX (3.5) for VT and compared to RR genotype (8.1) and RR + RX (3.4) for RCP. Thus, XX individuals could attain the VT and RCP at higher speeds, suggesting that they are able to sustain higher running speeds in lower exercise intensity domains. It could result in higher lipid acids oxidation, saving muscle glycogen and delaying the fatigue during prolonged exercises, which could be the advantage mechanism of this genotype to endurance performance.     

Evolution of an academic–public library partnership

A partnership to improve access to health information via an urban public library system was established in St. Louis, Missouri, in 2011. A multiyear project was outlined that included an information needs assessment, a training class for public library staff, information kiosks at library branches for delivering printed consumer health materials, and a series of health-related programming. The partnership evolved to include social service and community organizations to carry out project goals and establish a sustainable program that met the health and wellness interests of the community.     

Concept-guided development of technology in ‘traditional’ and ‘innovative’ schools: quantitative and qualitative differences in technology integration

The integration of technology into the classroom remains a challenge for those involved. A concept-guided approach to the development of technology has been suggested as a way of meeting this challenge. This multiple case study was performed in the context of a project in which five elementary schools in The Netherlands with a school concept that was labeled as either ‘traditional’ or ‘innovative’ developed and realized up to four technology-supported learning arrangements in line with their schools’ educational concepts. Through embedded case studies, including analysis of the learning arrangements and focus group interviews with the teachers involved, we found that in general the developed technology use became integrated in the teachers’ classroom practices at all schools to a similar extent. Some differences were found between the schools, but hardly any were found between the school types. Both practical and theoretical implications of these findings are discussed.     

Externalizing Problems in Head Start Children: An Ecological Exploration

The increased familial and environmental stressors affecting Head Start families over the last two decades have precipitated an escalation of mental health difficulties among participant children (Yoshikawa & Knitzer, 1997). Using an ecological framework (Bronfenbrenner, 1979). this study explored externalizing behavior problems among a group of Head Start children in a suburban county. Children were assessed for externalizing behavior problems in the home and classroom. Additionally, parents participated in interviews about a variety of ecological factors related to children's behavior problems. Almost one-quarter of the children were identified by their parents as having externalizing behavioral problems in the borderline or clinical range. Twice as many girls as boys had borderline or clinical levels of behavioral problems. Child externalizing behavior was positively associated with child internalizing behavior, parent psychological symptomatology, child temperament, family environment, and exposure to community violence. Children with parent-identified externalizing behavior did have specific social problem-solving skills deficits. Additionally, they were observed to have high levels of specific inappropriate behavior, but did not exhibit high levels of teacher-rated behavior problems. The implications of these findings for Head Start program planning are discussed.     

Knowledge about word structure in beginning readers: what specific links are there with word reading and spelling?

The present study had two aims: (1) to examine kindergarten (Kg) and first grade (G1) children’s early word structure knowledge, that is letter, phonological, morphological, and orthographic knowledge, and (2) to provide evidence of specific links between these various types of knowledge and word reading and spelling performance assessed in G1. A short longitudinal study was conducted with French-speaking children. Beyond phonological and morphological knowledge, identified here as in many other studies, the results provided evidence of a level of orthographic knowledge in the Kg children who exhibited an ability to process graphotactic constraints (i.e., legal combinations of letters). Moreover, whatever the type of items (affixed, pseudo-affixed, regular, or irregular words) being processed, either in reading or in spelling, letter naming was seen to be the strongest predictor of reading and spelling performance. The second important predictor related to phonological knowledge and more particularly phoneme extraction as a proximal predictor. Morphological knowledge appeared to be less important, and finally, the smallest contribution was made by orthographic knowledge.     

Dissonance Between Parent‐Selected Bedtimes and Young Children's Circadian Physiology Influences Nighttime Settling Difficulties

Nighttime settling difficulties (i.e., bedtime resistance, sleep‐onset delay) occur in about 25% of young children and are associated with attentional, behavioral, and emotional problems. We examined whether the timing of internal (endogenous) circadian melatonin phase (i.e., dim light melatonin onset; DLMO) and its relationship with parent‐selected bedtimes were related to nighttime settling behaviors. Fourteen regularly napping preschoolers (8 females; 30–36 months) participated in a 6‐day protocol (parent‐report of nighttime settling, actigraphic assessment of sleep onset latency, evening salivary DLMO). Average DLMO clock time was 07:40 p.m. ± 00:48 minutes, occurring 29 minutes ± 32 minutes prior to bedtime (lights‐out). Children with later DLMOs had longer sleep‐onset latencies (r = .62) and poorer success in falling asleep (r = ?.59). Children whose bedtimes were closer to their DLMO had longer sleep‐onset latencies (r = .72) and increased bedtime resistance (r = ?.54). We conclude that dissonance between parent‐selected bedtimes and children's circadian physiology may contribute to the development of nighttime settling difficulties in early childhood.     

Conflict management satisfaction and relational and sexual satisfaction

This study examines predictors of relational, and sexual, satisfaction. Specifically, it is hypothesized that the discrepancy between real and ideal conflict management style is antecedent to relational satisfaction, which is a direct antecedent of sexual satisfaction. It is suggested that communicating in the manner that one sees as ideal is important in predicting relational satisfaction. Surveys including measures for conflict management style, relational satisfaction, and sexual satisfaction were administered to 290 participants. These data were consistent with the proposed model.     

The Research Team Concept,II: (Still) An Approach to Graduate Training

This paper advocates for employing graduate research teams as a way to train graduate students. Research teams allow for a community of scholars to share knowledge and exchange ideas. By employing an apprenticeship-type program for graduate students, they are provided an opportunity to transition from a student to a young scholar. Such training prepares students to develop and implement their own research programs and train their future graduate students. Graduate students can be involved in conceptualizing research questions, designing studies, developing measuring instruments, gathering and analyzing data, and more. Nonetheless, implementing and organizing research teams can be an arduous process that should not be entered into lightly. This paper provides ideas for the construction of teams as well as issues to consider before implementing the team concept.
