Prenatal Maternal Stress and Child IQ

The evidence for negative influences of maternal stress during pregnancy on child cognition remains inconclusive. This study tested the association between maternal prenatal stress and child intelligence in 4,251 mother–child dyads from a multiethnic population-based cohort in the Netherlands. A latent factor of prenatal stress was constructed, and child IQ was tested at age 6 years. In Dutch and Caribbean participants, prenatal stress was not associated with child IQ after adjustment for maternal IQ and socioeconomic status. In other ethnicities no association was found; only in the Moroccan/Turkish group a small negative association between prenatal stress and child IQ was observed. These results suggest that prenatal stress does not predict child IQ, except in children from less acculturated minority groups.     

Construct Equivalence of PISA Reading Comprehension Measured With Paper‐Based and Computer‐Based Assessments

For many years, reading comprehension in the Programme for International Student Assessment (PISA) was measured via paper‐based assessment (PBA). In the 2015 cycle, computer‐based assessment (CBA) was introduced, raising the question of whether central equivalence criteria required for a valid interpretation of the results are fulfilled. As an extension of the PISA 2012 main study in Germany, a random subsample of two intact PISA reading clusters, either computerized or paper‐based, was assessed using a random group design with an additional within‐subject variation. The results are in line with the hypothesis of construct equivalence. That is, the latent cross‐mode correlation of PISA reading comprehension was not significantly different from the expected correlation between the two clusters. Significant mode effects on item difficulties were observed for a small number of items only. Interindividual differences found in mode effects were negatively correlated with reading comprehension, but were not predicted by basic computer skills or gender. Further differences between modes were found with respect to the number of missing values.     

Examining the impact of the Respect in Sport Parent Program on the psychosocial experiences of minor hockey athletes

ABSTRACT

Models of positive youth development suggest that athletes may be influenced by parent education programmes; however, there is little research examining the impact of such programmes on athlete outcomes. This study examined the impact of the Respect in Sport Parent Program on athlete outcomes among minor hockey players over three years. This study consisted of cross-sectional and longitudinal online surveys measuring athletes’ positive and negative developmental experiences, prosocial and antisocial behaviours, parental support and pressure, and sport enjoyment and commitment. Athletes completed at least one online survey during the study period (N = 366; 84.2% males; 14–19 years of age; M = 15.4 years), and 83 athletes completed multiple surveys for longitudinal analyses. Cross-sectional results comparing athletes in leagues adopting the programme at different time points indicated significant differences in prosocial behaviours towards teammates. Multilevel longitudinal analyses revealed improvements in athletes’ antisocial behaviours towards opponents, initiative, goal setting, and cognitive skills over time, regardless of whether they were in a league that implemented the programme. However, athletes in leagues that implemented the programme during the study reported greater improvements in antisocial behaviours towards opponents, and there were trends with respect to improved personal and social skills. These findings provide suggestions to improve the delivery and impact of parent education programmes in youth sport.     

Empirical identification of the major facets of Conscientiousness

Conscientiousness is often found to predict academic outcomes, but is defined differently by different models of personality. High school students (N = 291) completed a large number of Conscientiousness items from different models and the Big Five Inventory (BFI). Exploratory and confirmatory factor analysis of the items uncovered eight facets: Industriousness, Perfectionism, Tidiness, Procrastination Refrainment, Control, Cautiousness, Task Planning, and Perseverance. Correlations between these facets and the BFI revealed that all facets related strongly to Conscientiousness. Criterion-related validity was demonstrated by relationships between facets and academic outcomes such as grade-point-average, disciplinary infractions, and attainment of academic honors. Compared to BFI Conscientiousness, Industriousness and Perfectionism showed significantly stronger prediction of absenteeism and cognitive test scores, respectively. Results are discussed in terms of the usefulness of facet scores, the interpretation of personality scores for selection, and the development of intervention programs.     

Strategic technology planning in higher education

Higher education institutions struggle with planning for future needs, growth, and, sometimes, contraction. As student populations expand and as faculty members adopt new technologies, universities struggle to support these needs. To the casual observer, it may seem that the technology planning process is haphazard. This article details a process that organizations can use to develop a strategic plan to satisfy near‐ and long‐term technology needs. A case study of how this process was used to develop a technology roadmap at San Diego State University will be discussed.     

Science Teacher Learning of MBL-Supported Student-Centered Science Education in the Context of Secondary Education in Tanzania

Science teachers from secondary schools in Tanzania were offered an in-service arrangement to prepare them for the integration of technology in a student-centered approach to science teaching. The in-service arrangement consisted of workshops in which educative curriculum materials were used to prepare teachers for student-centered education and for the use and application of Microcomputer Based Laboratories (MBL)—a specific technology application for facilitating experiments in science education. Quantitative and qualitative data were collected to study whether the in-service arrangement impacted teacher learning. Teacher learning was determined by three indicators: (1) the ability to conduct MBL-supported student centered science lessons, (2) teachers’ reflection on those lessons and (3) students’ perceptions of the classroom environment. The results of the research indicate that the teachers’ were able to integrate MBL in their science lessons at an acceptable level and that they were able to create a classroom environment which was appreciated by their students as more investigative and open-ended.

The effects of economic status and recent experience on innovative behavior under environmental variability: An experimental approach

We build and empirically test a model that predicts the display of innovative behavior as a function of environmental change, with recent experience and economic status acting as moderators. We start with the model developed by Slevin (1971), which evolved from the so-called innovation boundary. This is the threshold beyond which the display of innovative behavior becomes attractive. We show how environmental change creates uncertainty about the position of the innovation boundary; however, this uncertainty is reduced by recent experiences. Furthermore, economic status serves as both an enhancer and an inhibitor of innovation. Our model was tested and largely confirmed in two experiments: one conducted in a laboratory setting and one conducted as a discrete choice experiment. Currently experiments are rarely conducted in the field of innovation studies. By presenting this evidence we also hope to encourage more authors to conduct experiments in their work.     

Trauma-related impairment in children—A survey in Sri Lankan provinces affected by armed conflict

ObjectivesThe present study examined traumatic experiences, PTSD, and co-morbid symptoms in relation to neuropsychological and school performance in school children affected by two decades of civil war and unrest.MethodThe epidemiological survey of children's mental health included a representative sample of 420 school children. Local teachers were trained to administer a translation of the UCLA-PTSD Index Form. The instrument and the epidemiological findings were validated by assessment through clinical expert interview, school grades, and neuropsychological testing in a subsample (N = 67).ResultsNinety-two percent of the children surveyed had experienced severely traumatizing events such as combat, bombing, shelling, or witnessing the death of a loved one. Twenty-five percent met the criteria for a diagnosis of PTSD. Traumatized children reported lasting interference of experiences with their daily life, which was corroborated by memory testing, scores in school performance and ratings of social withdrawal. Depressive symptoms and poor physical health were frequent in these children. The majority of trained teachers achieved valid results in the structured interviews.ConclusionPerformance and functioning in children are related to the total load of traumatic events experienced. An important component of psychosocial programs in post-conflict areas should include increasing community-based awareness of the consequences of traumatic stress, both as a preventative measure and as a way of decreasing stigmatization of affected individuals.
