Gene-environment processes linking aggression, peer victimization, and the teacher-child relationship

Aggressive behavior in middle childhood is at least partly explained by genetic factors. Nevertheless, estimations of simple effects ignore possible gene-environment interactions (G × E) or gene-environment correlations (rGE) in the etiology of aggression. The present study aimed to simultaneously test for G × E and rGE processes between aggression, on the one hand, and peer victimization and the teacher-child relationship in school, on the other hand. The sample comprised 124 MZ pairs and 93 DZ pairs assessed in Grade 1 (mean age = 84.7 months). Consistent with rGE, children with a presumed genetic disposition for aggression were at an increased risk of peer victimization, whereas in line with G × E, a positive relationship with the teacher mitigated the genetically mediated expression of aggression.     

Training mothers in elaborative reminiscing enhances children's autobiographical memory and narrative

This longitudinal intervention assessed children's memory at 2(1/2) years (short-term posttest; N=115) and their memory and narrative at 3(1/2) years (long-term posttest; N=100) as a function of maternal training in elaborative reminiscing when children were 1(1/2) to 2(1/2) years. At both posttests, trained mothers were more elaborative in their reminiscing than untrained mothers. At the long-term posttest, trained mothers were also more repetitive than untrained mothers. Children of trained mothers provided richer memories than children of untrained mothers at both posttests. Children of trained mothers also produced more accurate memories with researchers but only if they had high initial levels of self-awareness. Results are discussed with respect to theory and practice in autobiographical memory development.     

Teachers’ spaces for coping with change in the context of a reform effort

In this paper, we are interested in the emotional responses of teachers in the context of a reform effort, and our study is oriented toward describing the significance of these responses with respect to the space teachers create to deal with reform in their school. Our interest for educational reform incorporates and builds on the work of spatial theories and theories of emotions in education, and most notably the work of Andy Hargreaves whose conceptualization of “emotional geographies” provides an insightful link between emotion and space. This is done through a 2-year ethnographic study with six teachers that were involved in science program restructuring in their school. In this study, we explore three aspects of the spaces for coping with change that were created by this group of elementary teachers: (1) time and space as sources of social and emotional support; (2) teacher collegiality and trust; and (3) teachers’ moral values and concerns. Finally, this paper explores the implications for practice and policy from the development of spaces for teachers to process their feelings about change.

Social mobility: The potential of a genealogical approach

This article highlights the potential of taking a genealogical approach to researching social mobility based on empirical insights generated from a qualitative case study in a secondary school located in the South East of England. The study involved interviews with 42 students and the data lead to a deeper understanding of the role of families in inter- and intra-generational social movement. We begin by highlighting some limitations in existing research on social mobility. Next, the role of households and families in conditioning an individual's identity, dispositions, aspirations and choices is emphasised. We then present findings from the analysis of 42 genealogical work histories over three generations and explore the role of education and family background in shaping young people's employment aspirations. We argue that education has had little impact on overall mobility rates and suggest that whilst education has a significant role in mediating social mobility, the importance of family context should not be overlooked.     

Investigating Antecedents to the Experience of Flow and Reported Learning Among Social Networking Site Users

Using an online survey (N = 888), this study investigated if the experience of flow mediated the influence of perceived social networking site credibility and social capital affinity (the sense of community and likeness felt for people online) on perceived focused and incidental knowledge gain among social networking sites users. The findings indicated that flow acted as a partial mediator in this context. However, social capital affinity strongly predicted perceived social networking site credibility and flow. Both perceived social networking site credibility and flow were predictors of perceived focused learning while social capital affinity was a strong, direct predictor of perceived incidental knowledge gain in this sample.     

The Reality of Sustaining Community-Based Sport and Physical Activity Programs to Enhance the Development of Underserved Youth: Challenges and Potential Strategies

Many community-based sport and physical activity programs take a positive youth development approach when operating in underserved communities around the world (Forneris, Whitley, & Barker, 2013). However, one of the biggest challenges for these programs is sustainability (Lindsey, 2008). The purpose of this article is to present the 3 authors’ experiences related to program sustainability when working with community-based sport and physical activity programs using a positive youth development approach in underserved communities. The authors describe the challenges faced with program sustainability, including ineffective development approaches, building strong relationships with community partners, knowledge translation, and securing funding. Also described are the strategies used to overcome these challenges, such as planning, capacity building, recruitment, and evaluation. This article is intended to stimulate more open and honest discussions about the realities of positive youth development program sustainability around the world.     

Microfluidic system for near-patient extraction and detection of miR-122 microRNA biomarker for drug-induced liver injury diagnostics

Drug-induced liver injury (DILI) results in over 100 000 hospital attendances per year in the UK alone and is a leading cause for the post-marketing withdrawal of new drugs, leading to significant financial losses. MicroRNA-122 (miR-122) has been proposed as a sensitive DILI marker although no commercial applications are available yet. Extracellular blood microRNAs (miRNAs) are promising clinical biomarkers but their measurement at point of care remains time-consuming, technically challenging, and expensive. For circulating miRNA to have an impact on healthcare, a key challenge to overcome is the development of rapid and reliable low-cost sample preparation. There is an acknowledged issue with miRNA stability in the presence of hemolysis and platelet activation, and no solution has been demonstrated for fast and robust extraction at the site of blood draw. Here, we report a novel microfluidic platform for the extraction of circulating miR-122 from blood enabled by a vertical approach and gravity-based bubble mixing. The performance of this disposable cartridge was verified by standard quantitative polymerase chain reaction analysis on extracted miR-122. The cartridge performed equivalently or better than standard bench extraction kits. The extraction cartridge was combined with electrochemical impedance spectroscopy to detect miR-122 as an initial proof-of-concept toward an application in point-of-care detection. This platform enables the standardization of sample preparation and the detection of miRNAs at the point of blood draw and in resource limited settings and could aid the introduction of miRNA-based assays into routine clinical practice.     

Group procedures and applications for developing sociocultural competencies among immigrants

If immigrants are to get the best results in theirsocial and work worlds, they must possess not only therelevant cultural information, but also the requisitebehavioural skills inherent in the novel social rolesthat people acquire as members of the new country. This paper argues that the preferred training modelfor developing such competencies is one which utilizesrole-based learning in groups and incorporates aspectsof group counselling theory and practice. Effectivefacilitators of these immigrant groups should beskilled group leaders competent in taking participantsthrough the four stages - alliance building, culturalmapping, coaching and practice, and contract setting - involved in teaching each of severalkey sociocultural competencies. Group leaders will need to performparticular types of task and maintenance functions,and facilitate the development of group inclusion,control, and trust. To achieve this, facilitators arerecommended to use a range of micro skills for groupleading, processing, and counselling.     

Academic Adjustment and Learning Processes: a comparison of international and local students in first‐year university

This article examines the academic adjustment and learning processes of international and local first‐year students. Twenty first‐year local and international students participated in a semi‐structured interview study upon the completion of their first year in a Faculty of Commerce and Management. Students reported positive and negative critical incidents which helped or hindered their learning during the first year. In addition, students described their feelings, thoughts and behaviours in relation to these incidents. Critical incidents were coded, themes identified, and comparisons made across local and international student groups. The impact of particular teaching processes are considered, and implications for teaching and learning in the first year are discussed.
