Using the theory of planned behaviour to predict leisure educators’ intentions to use instructional technology

The Theory of Planned Behaviour (TPB) (Ajzen, 1991b) was applied to the prediction and explanation of the intention to use instructional technology by using a mail questionnaire (n = 406) of leisure educators in the United States and Canada. Based on structural equation modeling, it was found that the key determinants of the TPB, attitude toward instructional technology, subjective norm toward instructional technology, and perceived behavioural control toward instructional technology accounted for 50% of the leisure educators’ intention to use instructional technology. The strongest predictor of intention was attitude toward instructional technology, followed by subjective norm toward instructional technology and perceived behavioural control toward instructional technology. The findings provide insight into faculty members’ intention to develop and use instructional technology

Managing risk and consistency in the raw material supply chain for single use systems

As the bioprocessing industry moves increasingly towards single use systems (SUS), security of supply at the raw material level becomes imperative to quality. Long term supply of consistent, high quality materials desired for single use film is directly attributed to the stability, continuity and quality of raw material supply from the film manufacturer. This presentation will focus on the strategic selection of raw materials for a single use platform film in the bioprocessing industry to minimize risk associated with change notifications. Utilizing a quality by design approach, a single use film was formulated with no added Irgafos 168, enhanced abuse resistance and a low extractables and leachables profile. There are several factors that are critically important to understanding quality and risk of supply in raw material sourcing. This presentation will outline the raw material selection process established to ensure supply continuity and high quality desired for use in bioprocessing films. A comprehensive study was conducted on raw materials prior to film validation and quality controls were established to ensure consistency prior to processing into single use films

Impact of Tobacco-Pack Pictorial Warnings on Youth and Young adults: A Systematic Review of Experimental Studies

Introduction:We conducted a systematic review of the experimental literature on the impact of tobacco-pack pictorial warning labels (PWLs) on youth and young adults. Methods:We systematically searched computerized databases and the reference list of relevant articles. We included studies that used an experimental protocol to assess PWLs. Studies had to report findings for youth or young adult samples (aged \u3c 30 years). Thirty-one studies met the inclusion criteria, with a total sample size of 27506. Two coders independently coded all study characteristics and outcomes. Results:Twenty-eight studies experimentally evaluated PWLs for cigarette packs while three studies evaluated PWLs for smokeless tobacco packs. Generally, PWLs led to higher attention, stronger cognitive and affective reactions, more negative pack attitudes and smoking attitudes, and increased intentions not to use tobacco products compared to text warnings. PWLs were perceived to be more effective than text warnings for both cigarette packs and smokeless tobacco packs. Conclusions:The systematic review showed that PWLs on tobacco products are effective across a wide range of tobacco-related outcomes among young people. Gaps in the literature include a lack of research on tobacco initiation and cessation and a dearth of literature on non-cigarette tobacco products

Influence of Work on Elevated Blood Pressure in Hispanic Adolescents in South Texas.

Literature supports an association between work and cardiovascular disease in adults. The objective of this study was to examine the relationship between current work status and elevated blood pressure in Hispanic adolescents. Participants were students in Hidalgo County, located along the Texas-Mexico border. Participants enrolled in the cohort study in ninth grade with assessments completed once a year for up to three years. Participants completed a self-report survey, while staff measured height, weight, waist circumference, blood pressure, and were screened for acanthosis nigricans. A generalized linear regression model with a logit link function was constructed to assess current work status and elevated blood pressure. Of the 508 participants, 29% had elevated blood pressure, which was associated with being male and other chronic disease indicators (e.g., acanthosis nigricans, overweight/obesity). The mean probability for elevated blood pressure was higher among currently working adolescents compared to those who were not. Findings were statistically significant (p < 0.05) at baseline. The findings illustrate that a large proportion of adolescents along the Texas-Mexico border may have elevated blood pressure and that working may be associated with it. Subsequent research is needed to confirm these findings, as well as to identify the mechanism for how work may increase hypertension in adolescents

The Impact of an Adapted Climbing Program on Children with Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder impacts children’s participation in activities that require attention to instruction, sustained mental effort, and executive functioning. Physical activity has been correlated to improvement in attention in children with ADHD. Rock climbing challenges muscular endurance, attention, and route planning. Five participants, aged 8-13, participated in the climbing program. Attention was measured pre and post climbing intervention with Trail Making Test B (TMT-B) for time to complete. Exercise intensity was measured by heart rate. Parent feedback on behavior was collected with the Conner’s Parent Rating Scale (CPRS). The social validity of the intervention was measured by the IRP-15 measures. Statistically, significant intrasession attention improvements were noted in all 5 climbers (p=.43). Two climbers were consistently working at a moderate intensity (40-60% HRmax) while 3 climbers maintained a light level of intensity (20-40% HRmax). No statistically significant improvements were found on the CPRS, although improvements are noted with qualitative reports from parents. The IRP-15 showed 100% of parents believed rock climbing was an effective intervention for their children with ADHD. Rock climbing at a light to moderate intensity is associated with improvements in attention and behavior in children with ADHD
