Defining Moments / A Life Portrait

Defining Moments / A Life Portrait In his MFA Thesis Exhibition, Defining Moments / A Life Portrait, Timothy Haerens explores and celebrates our connectedness to one another as members of the human race. “We are here to awaken from the illusion of our separateness.” Haerens chose this quote from the Vietnamese Buddhist monk and peace activist, Thich Nhat Hanh, as the inspiration for his show because it affirms his belief that we are linked to one another by virtue of our humanness. Through his abstract paintings on canvas and plexiglass, as well as through his prints and collagraphs, Haerens reflects on many facets of life – the sweet and sour moments we experience as part of the human condition. His art elicits an internal dialogue in an attempt to better understand himself and the world around him

Bicycling to school during the transition from childhood into adolescence : a six-year longitudinal study

Little is known about bicycling to school as children age. At baseline (2002) self-report data from 1070 children were gathered (51.9% boys; mean age: 10 years). The measurements were repeated in 2003 (n = 1039), 2004 (n = 907), 2005 (n = 549) and 2008 (n = 515). The rates of children bicycling to school significantly varied across time points from 46% at the age of ten, 69% at the age of 11, 83% at the age of 12, 70% at the age of 13 toward 78% at the age of 16. Starting from the age of 11, the average duration of time spent bicycling to school significantly increased over time. According to multilevel regression analyses 13.6% of the variance in rates of bicycling to school was situated at the school level. 39.6% at the pupil level and 46.7% at the measurement level. The differences in rates and durations across time points were independent from gender, BMI, SES and having siblings. Pupils engaging in bicycling to school at younger ages had a higher change of engaging in bicycling to school at 16 years old (ORs: 2.69-7.61; ICC bicycling rates: 0.46, ICC bicycling durations: 0.82). This finding emphasizes the need for promoting bicycling to school at young age

Developmental change in motor competence : a latent growth curve analysis

Background: The development of childhood motor competence demonstrates a high degree of inter-individual variation. Some children's competence levels increase whilst others' competence levels remain unchanged or even decrease over time. However, few studies have examined this developmental change in motor competence across childhood and little is known on influencing factors. Aim: Using latent growth curve modeling (LGCM), the present longitudinal study aimed to investigate children's change in motor competence across a 2-year timespan and to examine the potential influence of baseline weight status and physical fitness on their trajectory of change in motor competence. Methods: 558 children (52.5% boys) aged between 6 and 9 years participated in this study. Baseline measurements included weight status, motor competence (i.e., Korperkoordinationstest fur Kinder; KTK) and physical fitness (i.e., sit and reach, standing long jump and the 20 m shuttle run test). Motor competence assessment took place three times across a 2-year timespan. LGCM was conducted to examine change in motor competence over time. Results: The analyses showed a positive linear change in motor competence across 2 years (beta = 28.48, p < 0.001) with significant variability in children's individual trajectories (p < 0.001). Girls made less progress than boys (beta = -2.12, p = 0.01). Children who were older at baseline demonstrated less change in motor competence (beta = -0.33, p < 0.001). Weight status at baseline was negatively associated with change in motor competence over time (beta = -1.418, p = 0.002). None of the physical fitness components, measured at baseline, were significantly associated with change in motor competence over time. Conclusion and Implications: This longitudinal study reveals that weight status significantly influences children's motor competence trajectories whilst physical fitness demonstrated no significant influence on motor competence trajectories. Future studies should further explore children's differential trajectories over time and potential factors influencing that change

How the Belgian wind farm business made us discover the challenging environment of marine sand dunes

During the last decade, it has become clear that sand dunes are important features in the Belgian wind farm concession area. Because they influence not only the design seabed levels, but also the hydrodynamic forcings and installation methods for both cable and foundations, the study of the seabed morphodynamics is essential for all wind farm projects. This paper starts with an overview of the geographic and morphological setting of the Belgian wind farm concession areas and presents an overview of the key features of the bedforms in the different concessions. Next the importance and impact of the sand dunes during the design and development of these wind farms is illustrated by exploring the different types of studies and investigations which have been performed in relation to seabed & morphology, the hydrodynamic loadings, the installation methods and the environmental impact assessments

Does the level of motivation of physical education teachers matter in terms of job satisfaction and emotional exhaustion? A person-centered examination based on self-determination theory

Grounded in self-determination theory (SDT), prior research has demonstrated that physical education (PE) teachers may have different reasons to engage in teaching. Although some person-centered studies have identified varied motivational profiles in PE teachers, none of these studies have included the three forms of motivation (i.e., autonomous motivation, controlled motivation, and amotivation). This study aims to identify teachers’ motivational profiles, using the three forms of motivation. Moreover, differences between the obtained profiles in terms of job satisfaction and emotional exhaustion were examined. A sample of 107 primary school PE teachers participated. Four distinct motivational profiles were identified: “relatively amotivated,” “somewhat motivated,” “autonomous-controlled motivated,” and “relatively autonomously motivated.” Results showed that the predominantly autonomously motivated PE teachers reported the most adaptive pattern of outcomes. Although PE teachers from the “relatively autonomously motivated” group did not differ in terms of job satisfaction when compared to those in the “autonomous-controlled motivated” group, the former displayed lower values of emotional exhaustion. These findings support SDT in that more motivation is not necessarily better if this additional motivation comes from controlled reasons. These results could raise awareness among school stakeholders about the importance of increasing PE teachers’ autonomous motivation

Relationship of physical activity and dietary habits with body mass index in the transition from childhood to adolescence : a 4-year longitudinal study

OBJECTIVE: To explore the relationship between several physical activity (PA) and dietary behaviours and BMI Z-score and to investigate the relationship between changes in these variables and in the BMI Z-score over a 4-year period from childhood to adolescence. DESIGN: Longitudinal study in which children were included in the fifth grade and measured for four consecutive years. Dietary and PA behaviours as well as height and weight were measured by means of self-reported validated questionnaires. SETTING: Fifty-nine Flemish elementary schools. SUBJECTS: The baseline sample consisted of 51·9 % boys and the mean age was 10 (sd 0·4) years. During the first measurement year (2002), data on 1670 fifth graders were gathered. These measurements were repeated after 1 (n 1557), 2 (n 1151) and 3 (n 807) years. RESULTS: Significant inverse relationships with BMI Z-score were observed for frequency of breakfast consumption (β = -0·033, se = 0·012) and frequency of sports participation (β = -0·011, se = 0·004) across four time points. Significant inverse relationships between changes in BMI Z-score and changes in frequency of sports participation (β = -0·011, se = 0·006) and hours of physical education (PE; β = -0·052, se = 0·023) were observed, meaning that decreases in sports participation and hours spent in PE were associated with increases in BMI Z-score. CONCLUSIONS: The present study provides an important insight into different dietary and PA behaviours related to (changes in) BMI Z-score during the transition from childhood to adolescence

Why do sport coaches adopt a controlling coaching style? The role of an evaluative context and psychological need frustration

In this study, involving 585 youth sport coaches (Mage = 35.76), we investigated whether coaches who perceive their environment to be highly evaluative would report acting in a more controlling or pressuring way. In a subsample (N = 211, Mage = 38.14), we examined the explanatory role of coaches’ experiences of psychological need frustration in this relation. We also considered whether years of coaching experience would serve as a buffer against the adverse effects of an evaluative context. In line with the tenets of Self-Determination Theory (Ryan & Deci, 2017), results of structural equation modeling indicated that an evaluative context related to the use of a more controlling coaching style, with experiences of need frustration accounting for this relation. Coaching experience did not play any moderating role, suggesting that even more experienced coaches are vulnerable to the harmful correlates of an evaluative sport context
