A Longitudinal Person-Centered Examination of Affinity for Aloneness Among Children and Adolescents

Affinity for aloneness among youth often is viewed negatively. However, some youth may enjoy solitude for positive reasons, rather than because of social anxiety. The prevalence and adjustment over time of youth with high affinity for aloneness is unclear. Groups of children (N = 605, M_age = 9.29) and adolescents (N = 596, M_age = 12.20) were identified using affinity for aloneness and social anxiety scores, and group differences in adjustment were assessed. Latent class analyses revealed four groups at T1 and T2 for both samples. Among these were Normative (Low.affinity_for_aloneness-Low.social_anxiety) and Affinity for Aloneness (High.affinity_for_aloneness-LowMod.social_anxiety) groups. These groups did not differ longitudinally in adjustment. Having elevated levels of affinity for aloneness without high social anxiety is relatively benign.     

Dimensions of coping and anxiety symptoms in a community sample of young children

Coping style plays an important role in children’s wellbeing. This paper describes the patterns of associations between children’s self-reported coping styles and symptoms of anxiety in order to determine whether particular dimensions are associated with better adjustment. Participants were 2566 children (1268 girls, 1298 boys) aged 7–11 years attending 15 schools in the South East of England. Results showed that aspects of coping were differentially associated with children’s self-reported anxiety. Patterns of association also varied by age and gender. Dimensions of coping were shown to form distinct adaptive and maladaptive coping styles which were also differentially associated with anxiety. Analysis of these styles indicated that it is the absence of maladaptive coping strategies, rather than the presence of adaptive strategies, that is significant in emotional wellbeing. These findings suggest that interventions designed to reduce or extinguish maladaptive coping styles may be of particular benefit in facilitating emotional wellbeing.     

Mechanics of Batting: Effect of Stride Technique on Ground Reaction Forces and Bat Velocities

The benefits associated with being physically active are well documented, but a significant proportion of the population is insufficiently active. Physical inactivity is a major health risk factor in our society, and physical education programs are consistently identified as a means to address this concern. The purpose of this article is to use the social-ecological model as a framework to examine ways in which physical education programs can play an important role in promoting physical activity. Policies that require time allocations and resources for physical education and physical activity in schools and community designs that provide infrastructure that makes being physically active accessible and convenient are important factors in making schools and communities healthier spaces. It is clear, however, that policies alone are not sufficient to address concerns about physical inactivity. We must consider individual factors that influence decisions to be physically active in efforts to engage children in physical education programs that promote active lifestyles. The learning climate that teachers create determines what students do and learn in physical education classes. Ensuring that students see value in the content presented and structuring classes so that students believe they can experience success when they exert effort are key elements in an effective motivational climate. Efforts to address public health concerns about physical inactivity require a comprehensive approach including quality physical education. It is critical that kinesiology professionals emerge as leaders in these efforts to place physical education programs at the center of promoting children's physical activity.     

Tackle and impact detection in elite Australian football using wearable microsensor technology

Abstract

The effectiveness of a wearable microsensor device (MinimaxX^TM S4, Catapult Innovations, Melbourne, VIC, Australia) to automatically detect tackles and impact events in elite Australian football (AF) was assessed during four matches. Video observation was used as the criterion measure. A total of 352 tackles were observed, with 78% correctly detected as tackles by the manufacturer’s software. Tackles against (i.e. tackled by an opponent) were more accurately detected than tackles made (90% v 66%). Of the 77 tackles that were not detected at all, the majority (74%) were categorised as low-intensity. In contrast, a total of 1510 “tackle” events were detected, with only 18% of these verified as tackles. A further 57% were from contested ball situations involving player contact. The remaining 25% were in general play where no contact was evident; these were significantly lower in peak Player Load? than those involving player contact (P < 0.01). The tackle detection algorithm, developed primarily for rugby, was not suitable for tackle detection in AF. The underlying sensor data may have the potential to detect a range of events within contact sports such as AF, yet to do so is a complex task and requires sophisticated sport and event-specific algorithms.     

Working on educational research methods with masters students in an international online learning community

In this paper we discuss the background to this study in the development of the international MSc e‐Learning Multimedia and Consultancy. The aims of the study focus on the conditions for achieving communication, interaction and collaboration in open and flexible e‐learning environments. We present our theoretical framework that has informed the design of programme as a whole which is based on a socio‐constructivist perspective on learning. Our research is placed within an action research framework and we outline our position within the critical or emancipatory tradition and also our standpoint on the use of ICT in education. We discuss the design of the programme and also our pedagogical approach and describe in detail the particular context for this study. We report on the student experience of being learners on this module, their perceptions of what they have gained most from learning from and with each other and their responses to the various ways in which ‘scaffolding’ has been designed and implemented by the tutors. Finally we offer some reflections on the conditions for achieving well‐orchestrated interdependence in open and flexible e‐learning environments.     

The development of a small-scale survey instrument of UK teachers to study professional use (and non-use) of and attitudes to social media

This paper documents the creation, implementation and analysis of a survey instrument designed to reveal patterns of use and attitudes towards the value of social media by UK teachers. The study was motivated to discover which teachers use social media professionally, how they use it (both personally and professionally) and attitudes to social media as a professional tool (for their students' and their own professional use). The instrument was created from verbal data from two focus group discussions regarding the use of social media in education. Attitude statements were included verbatim when practical. This instrument was placed online and practising teachers invited to complete it (n?=?216). Exploratory factor analysis and hierarchical clustering identified 9 factors from 54 attitude statements and 5 distinct teacher groups. The rich data allowed each group to be carefully defined, providing potentially invaluable information to school leaders when developing social media projects to recognize and accommodate the full range of teacher concerns and experience. The paper also addresses methodological concerns regarding instrument creation, dealing with missing data and the impact of missing data on subsequent analysis.
