Evaluation of Work Place Group and Internet Based Physical Activity Interventions on Psychological Variables Associated with Exercise Behavior Change
The purpose of this research was to compare group-based and internet-based physical activity interventions in terms of desirability, participants characteristics, exercise self-efficacy, and barrier self-efficacy. Pretest questionnaires were completed prior to voluntary enrollment into either of the ten-week physical activity interventions. Both interventions were based on Social Cognitive Theory and the Transtheoretical Model. Interventions were followed with posttest questionnaires. Results demonstrated that the internet intervention attracted more participants, but only the grou-based participants showed significant increases in exercise and barrier self-efficacy. At pretest, participants who selected the internet intervention were significantly lower in life and job satisfaction than those who selected the group intervention. Results suggested that traditional group-based exercise interventions are helpful for improving cognitions associated with exercise behavior change (e.g., exercise self-efficacy) and that the internet intervention may help employees who fall into an âunhappy employeeâ typology
Simulated learning: Assessing student perceptions of skill development and employability in a criminology course
Internationally, there is an increasing focus on enhancing student employability as an outcome
of successful university study (Pavlin and Svetlik 2014). While definitions of employability
remain contested, the marketisation of universities in the UK and globally, (Wilton, 2014) has
proliferated managerial approaches and metrics to assess student outcomes. The emergent
Teaching Excellence Framework in the UK (Office for Students, 2018) intends to include
graduate 'employment' within their metrics to assess teaching excellence. Thus, universities
have implemented a range of approaches to developing the employability of their students,
whether curricular, extra-curricular, or co-curricular.
This paper will outline a rationale for developing a simulation module for criminology
undergraduate students, along with a description of how the module was operationalised
adopting experiential learning approaches and utilising models of reflection (Schon, 1983, Gibbs,
1988). The module was developed in partnership with practitioners, and adopted six active
learning techniques to deliver student centred learning (O'Neill and McMahon 2005):
outside speakers - visiting criminal justice professionals; criminal justice agency student visits;
the provision of a reflective student work book; service learning in the form of opportunities for
student placements; assessments designed to facilitate student reflection on their own career
pathways, and an imaginary case study approach framework for the teaching delivery.
Using summative assessments as a data set, a thematic analysis highlighted from students' own
perspective, how their employability and skills have been developed as a consequence of
undertaking the module. These include articulating transferable skills (Monks et al, 2009,
Pollard et al 2015; Jackson 2016), personal growth through developing empathy and compassion
and the identification of new opportunities. Finally, pragmatic
Single Crystal Growth Tricks and Treats
Single crystal growth is a widely explored method of synthesizing materials
in the solid state. The last few decades have seen significant improvements in
the techniques used to synthesize single crystals, but there has been
comparatively little discussion on ways to disseminate this knowledge. We aim
to change that. Here we describe the principles of known single crystal growth
techniques as well as lesser-known variations that have assisted in the
optimization of defect control in known materials. We offer a perspective on
how to think about these synthesis methods in a grand scheme. We consider the
temperature interdependence with the reaction time as well as ways to carry out
synthesis to scale up and address some outstanding synthesis challenges. We
hope our descriptions will aid in technological advancements as well as further
developments to gain even better control over synthesis
Moderators of implicit-explicit exercise cognition concordance
Investigating implicitâexplicit concordance can aid in understanding underlying mechanisms and possible intervention effects. This research examined the concordance between implicit associations of exercise with health or appearance and related explicit motives. Variables considered as possible moderators were behavioral regulations, explicit attitudes, and social desirability. Participants (N = 454) completed measures of implicit associations of exercise with health and appearance and questionnaire measures of health and appearance motives, attitudes, social desirability, and behavioral regulations. Attitudes significantly moderated the relationship between implicit associations of exercise with health and health motives. Identified regulations significantly moderated implicitâexplicit concordance with respect to associations with appearance. These results suggest that implicit and explicit exercise-related cognitions are not necessarily independent and their relationship to each other may be moderated by attitudes or some forms of behavioral regulation. Future research that takes a dual-processing approach to exercise behavior should consider potential theoretical moderators of concordance.</jats:p
Older and More Experienced? Comparing Mainland Chinese International Students in Canada on Social Cognitive Correlates of Leisure Time Physical Activity, Acculturation, and Mental Health by Study Year
Background: Physical activity is a mandatory component of many university programs in China and there is evidence that Chinese students value physical activity for health (Chen & Liu, 2008); however, academics are generally prioritized as students advance in their studies (Ha, Macdonald, & Pang, 2010). Among international students in the United States, Asian students were found to have some of the lowest rates of physical activity, which could be linked with many combinations of cultural, environmental, and individual barriers (Yoh, Yang, & Gordon, 2008). Physical activity may aid in healthy transitions for Chinese international students. Aim: Chinese international students were compared by study year on physical activity, mental health, culture, and social cognitive theory variables. Method: First year (n = 92), second year (n = 52), and senior (n = 77) international students studying in Canada were compared on physical activity, self-efficacy, intention, access, stress, acculturative stress, subjective well-being, acculturation, and self-construal. The relationships between the social cognitive, mental health, culture variables, and physical activity were also compared. Results: Senior students perceived fewer places to do physical activity and more discrimination compared to first- and second-year students. Senior students experienced more academic pressure and guilt towards their family compared to second year students. First year students reported more general stress compared to second year students. Self-efficacy, intention, and exercise to reduce stress shared relationships with vigorous physical activity. Subjective well-being was related to moderate physical activity, and self-efficacy and independent self-construal were related to walking. Walking decreased by study year. Conclusions: Physical activity may be used to improve mental health for Chinese international students, but interventions may need to be adjusted or implemented depending on the academic stage of the student
A school-based randomized controlled trial to improve physical activity among Iranian high school girls
Background: Physical activity (PA) rates decline precipitously during the high school years and are consistently lower among adolescent girls than adolescent boys. Due to cultural barriers, this problem might be exacerbated in female Iranian adolescents. However, little intervention research has been conducted to try to increase PA participation rates with this population. Because PA interventions in schools have the potential to reach many children and adolescents, this study reports on PA intervention research conducted in all-female Iranian high schools. Methods: A randomized controlled trial was conducted to examine the effects of two six-month tailored interventions on potential determinants of PA and PA behavior. Students (N = 161) were randomly allocated to one of three conditions: an intervention based on Pender's Health Promotion model (HP), an intervention based on an integration of the health promotion model and selected constructs from the Transtheoretical model (THP), and a control group (CON). Measures were administered prior to the intervention, at post-intervention and at a six-month follow-up. Results: Repeated measure ANOVAs showed a significant interaction between group and time for perceived benefits, self efficacy, interpersonal norms, social support, behavioral processes, and PA behavior, indicating that both intervention groups significantly improved across the 24-week intervention, whereas the control group did not. Participants in the THP group showed greater use of counter conditioning and stimulus control at post-intervention and at follow-up. While there were no significant differences in PA between the HP and CON groups at follow-up, a significant difference was still found between the THP and the CON group. Conclusion: This study provides the first evidence of the effectiveness of a PA intervention based on Pender's HP model combined with selected aspects of the TTM on potential determinants to increase PA among Iranian high school girls

A longitudinal and cross-sectional examination of the relationship between reasons for choosing a neighbourhood, physical activity and body mass index
<p>Abstract</p> <p>Background</p> <p>The purpose of this study was to examine the relationship between body mass index and neighborhood walkability, socioeconomic status (SES), reasons for choosing neighborhoods, physical activity, fruit and vegetable intake, and demographic variables.</p> <p>Methods</p> <p>Two studies, one longitudinal and one cross-sectional, were conducted. Participants included adults (n = 572) who provided complete data in 2002 and 2008 and a concurrent sample from 2008 (n = 1164). Data were collected with longitudinal and cross-sectional telephone surveys. Objective measures of neighborhood characteristics (walkability and SES) were calculated using census data and geographic information.</p> <p>Results</p> <p>In the longitudinal study, neighborhood choice for ease of walking and proximity to outdoor recreation interacted with whether participants had moved during the course of study to predict change in BMI over 6 years. Age, change in activity status, and neighborhood SES were also significant predictors of BMI change. Cross-sectionally, neighborhood SES and neighborhood choice for ease of walking were significantly related to BMI as were gender, age, activity level and fruit and vegetable intake.</p> <p>Conclusions</p> <p>Results demonstrate that placing importance on choosing neighborhoods that are considered to be easily walkable is an important contributor to body weight. Findings that objectively measured neighbourhood SES and neighborhood choice variables contributed to BMI suggest that future research consider the role of neighborhood choice in examining the relationships between the built environment and body weight.</p
An assessment of climate change and health vulnerability and adaptation in dominica
A climate change and health vulnerability and adaptation assessment was conducted in Dominica, a Caribbean small island developing state located in the Lesser Antilles. The assessment revealed that the countryâs population is already experiencing many impacts on health and health systems from climate variability and change. Infectious diseases as well as food and waterborne diseases pose continued threats as climate change may exacerbate the related health risks. Threats to food security were also identified, with particular concern for food production systems. The findings of the assessment included near-term and long-term adaptation options that can inform actions of health sector decision-makers in addressing health vulnerabilities and building resilience to climate change. Key challenges include the need for enhanced financial and human resources to build awareness of key health risks and increase adaptive capacity. Other small island developing states interested in pursuing a vulnerability and adaptation assessment may find this assessment approach, key findings, analysis, and lessons learned usefulThis research was funded by Health Canad
Examining the Potential Disconnect Between Parentsâ Perceptions and Reality Regarding the Physical Activity Levels of Their Children
Background: Parental support plays an important role in facilitating the participation of children in physical activity. However, there is evidence that parents overestimate their childâs level of physical activity â this may lead to inaction in promotion attempts by parents. This potential disconnect between parental perceptions and reality was recently the focus of the âThink Againâ social marketing campaign developed by PartipACTION.
Purpose: To qualitatively explore parentsâ perceptions of the Think Again advertisements, and the possible disconnect between perceptions and reality regarding their childrenâs physical activity levels.
Method: Semi-structured interviews were conducted with 12 mothers and 12 fathers of children aged 5-11 years attending a supervised recreation class. A thematic analysis was applied to the collected data.
Results: The advertisements were generally well received by the parents in serving as a reminder of how much physical activity their children should be getting. Less than half of parents believed their children were attaining physical activity guidelines although the majority believed they were sufficiently active given perceived time constraints for both them and their child. Most parents believed they could accurately estimate how active their child was but that other parents may have difficulty due to reliance on schools and organized recreation to provide opportunities for physical activity.
Conclusion: PSAs have a role to play in increasing parental awareness of physical activity guidelines and communicating the importance of physical activity. More creative approaches will be needed to address the disconnect in the perceptions between sufficient and recommended levels of physical activity
