Predictors of Swimming Ability among Children and Adolescents in the United States

Swimming is an important source of physical activity and a life skill to prevent drowning. However, little research has been conducted to understand predictors of swimming ability. The purpose of this study was to understand factors that predict swimming ability among children and adolescents in the United States (US). This was a cross-sectional survey conducted between February and April of 2017 across five geographically diverse cities. Participants were accessed through the Young Christian Men’s Association (YMCA) and included parents of children aged 4–11 years old and adolescents aged 12–17 years old. Independent t-test, analysis of variance (ANOVA), and univariate and multivariate analyses were conducted. Several factors were significant (p ≤ 0.05) predictors of swimming ability and explained 53% of the variance in swimming ability. Variables that were positively associated with swimming ability included: ability of parent(s) to swim, child/adolescent age, a best friend who enjoys swimming, water-safety knowledge, pool open all year, and encouragement to swim from parent(s). Variables that were negatively associated with swimming ability included: fear of drowning, being African American, and being female. Interventions and programs to improve the swimming ability of children and adolescents could be developed with these predictors in mind

THE VALUE OF USDA OUTLOOK INFORMATION: AN INVESTIGATION USING EVENT STUDY ANALYSIS

The economic value of public situation and outlook information has long been a subject of debate. The purpose of this paper is to investigate the economic value of USDA WASDE reports in corn and soybean markets. The investigation is based on event study analysis, with the "events" consisting of the release of all monthly USDA WASDE reports for corn and soybeans from 1985 through 1998. The WASDE reports during the sample period are divided into two groups: one that represents "pure" outlook information and one that represents a "mix" of situation and outlook information. The statistical tests can be placed into two categories: mean price reaction and volatility reaction. Overall, the results suggest that USDA outlook information has a significant impact in corn and soybean markets. The most notable impact is found in options markets, where implied volatility consistently declines after the release of WASDE reports. For the group of monthly reports containing only outlook information, implied volatility for both corn and soybeans was lower on the report day than on the previous day about 60 percent of the time. The difference in mean implied volatility on the day of the report and on the previous day for both corn and soybeans was significantly different from zero. The average magnitude of the drop was between about two- and three-tenths of a percentage point (of annualized implied volatility), which would appear to be an economically non-trivial decrease. Hence, it can be concluded that USDA outlook information reduces the uncertainty of market participants' expected distribution of future prices. This reduction in market uncertainty is unambiguously welfare-enhancing.Crop Production/Industries, Marketing,

THE ROLE OF MARKET ADVISORY SERVICES IN CROP MARKETING AND RISK MANAGEMENT: A PRELIMINARY REPORT OF SURVEY RESULTS

The purpose of this report is to provide a preliminary summary of the results of a survey designed to help answer the questions about subscriber use of market advisory services. Importantly, this research is a cooperative partnership between the University of Illinois and the Data Transmission Network. The survey participants are commercial producers of major grain, oilseed and fiber crops, representing important agricultural areas of the US. The survey has three broad objectives, including 1) how US producers perceive the riskiness of various aspects of farming; 2) how US producers manage farm business risk, and 3) how US producers select and use market advisory services.Marketing, Risk and Uncertainty,

Cook It Up! A community-based cooking program for at-risk youth: overview of a food literacy intervention

<p>Abstract</p> <p>Background</p> <p>In Canada, there are limited occasions for youth, and especially at-risk youth, to participate in cooking programs. The paucity of these programs creates an opportunity for youth-focused cooking programs to be developed, implemented, and evaluated with the goal of providing invaluable life skills and food literacy to this potentially vulnerable group. Thus, an 18-month community-based cooking program for at-risk youth was planned and implemented to improve the development and progression of cooking skills and food literacy.</p> <p>Findings</p> <p>This paper provides an overview of the rationale for and implementation of a cooking skills intervention for at-risk youth. The manuscript provides information about the process of planning and implementing the intervention as well as the evaluation plan. Results of the intervention will be presented elsewhere. Objectives of the intervention included the provision of applied food literacy and cooking skills education taught by local chefs and a Registered Dietitian, and augmented with fieldtrips to community farms to foster an appreciation and understanding of food, from 'gate to plate'. Eight at-risk youth (five girls and three boys, mean age = 14.6) completed the intervention as of November 2010. Pre-test cooking skills assessments were completed for all participants and post-test cooking skills assessments were completed for five of eight participants. Post intervention, five of eight participants completed in-depth interviews about their experience.</p> <p>Discussion</p> <p>The <it>Cook It Up! </it>program can provide an effective template for other agencies and researchers to utilize for enhancing existing programs or to create new applied cooking programs for relevant vulnerable populations. There is also a continued need for applied research in this area to reverse the erosion of cooking skills in Canadian society.</p

Shingles Immunity and Health Functioning in the Elderly: Tai Chi Chih as a Behavioral Treatment

Both the incidence and severity of herpes zoster (HZ) or shingles increase markedly with increasing age in association with a decline in varicella zoster virus (VZV)-specific immunity. Considerable evidence shows that behavioral stressors, prevalent in older adults, correlate with impairments of cellular immunity. Moreover, the presence of depressive symptoms in older adults is associated with declines in VZV-responder cell frequency (VZV-RCF), an immunological marker of shingles risk. In this review, we discuss recent findings that administration of a relaxation response-based intervention, tai chi chih (TCC), results in improvements in health functioning and immunity to VZV in older adults as compared with a control group. TCC is a slow moving meditation consisting of 20 separate standardized movements which can be readily used in elderly and medically compromised individuals. TCC offers standardized training and practice schedules, lending an important advantage over prior relaxation response-based therapies. Focus on older adults at increased risk for HZ and assay of VZV-specific immunity have implications for understanding the impact of behavioral factors and a behavioral intervention on a clinically relevant end-point and on the response of the immune system to infectious pathogens

The Impact of Situation and Outlook Information in Corn and Soybean Futures Markets: Evidence from WASDE Reports

The purpose of this study was to examine the impact of situation and outlook information from World Agricultural Supply and Demand Estimates (WASDE) in corn and soybean futures markets over the period 1985 to 2006. Results indicate that WASDE reports containing National Agricultural Statistics Service (NASS) crop production estimates and other domestic and international situation and outlook information have the largest impact; causing return variance on report sessions to be 7.38 times greater than normal return variance in corn futures and 6.87 times greater than normal return variance in soybean futures. WASDE reports limited to international situation information and domestic and international outlook information have a smaller impact. The results show that the impact of WASDE reports has increased over time.corn, market impact, outlook, situation, soybeans, WASDE, Agribusiness, Crop Production/Industries, Financial Economics, Q100, Q110, Q130,

An Investigation of Youth Swimming Skills and Method of Instruction

Drowning is a leading cause of death for US children. Teaching youth to swim in a formal setting from certified instructors is a consistent drowning prevention recommendation. Purposes for this investigation was to examine type of swimming instruction and ability to swim and compare to attitudes toward swimming among US youth. Methods were similar to previous USA Swimming studies in 2008 and 2010. YMCA associations in five cities were used to recruit adolescent survey respondents (n=600) aged 12-18 years. Results showed African American youth had the lowest rate of formal swimming instruction (29%) compared to White (32%) and Hispanic (42%) peers. Free/reduced lunch qualifiers reported a 23% formal instruction rate as compared to 43% of non-qualifiers. Formally instructed youth were 2.35 times more likely to report being a skilled swimmer (86%) compared to informally instructed youth (72%). Formal swimming instruction is recommended, and interventions need to target underserved populations

Getting the Most Out of Giving: Concretely Framing a Prosocial Goal Maximizes Happiness

Across six field and laboratory experiments, participants assigned a more concretely-framed prosocial goal (e.g., making someone smile or increasing recycling) felt happier and reported creating greater personal happiness after performing a goal-directed act of kindness than did those who were assigned a functionally similar, but more abstractly-framed, prosocial goal (e.g., making someone happy or saving the environment). Moreover, mediation analyses revealed that this effect was driven by differences in the size of the gap between participants' expectations and reality. Compared to those who pursued an abstractly-framed prosocial goal, those who pursued a concretely-framed goal perceived that the actual outcome of their goal-directed efforts more accurately matched their expectations, causing them to experience a greater boost in happiness. Evidence that participants are unable to predict this effect, believing that pursuing abstractly-framed prosocial goals would have either an equal or greater positive impact on their own happiness, is also presented

Splashpads, Swings, and Shade: Parents\u27 Preferences for Neighbourhood Parks

Background Physical activity is a modifiable behavior that can help curtail the increasing worldwide problem of childhood obesity. Appropriate recreational opportunities, including neighborhood parks, are particularly important for promoting physical activity among children. Because children\u27s use of parks is mainly under the influence of their parents, understanding parents\u27 preferences is essential for creating the most inviting and usable park space to facilitate children\u27s physical activity. Methods Eighty-two intercept interviews were conducted with a heterogeneous sample of parents / guardians watching their children at neighborhood parks in London, Ontario. Parents / guardians were asked questions about how often they frequent the park, whether it is the closest to their residence, and their likes / dislikes for the park. Strategies to ensure trustworthiness of the data were employed. Results Interviewees attended their park of choice between 1–7 times per week with the average being 2.5 times per week. Only 49% of respondents frequented the park closest to their starting destination (home or daycare facility), and the majority traveled more than 4 km to get to the park. For those who chose to travel a significant distance to attend their park of choice, park location was not as important as the amenities they desired. Parents\u27 main reasons for choosing parks were: water attractions, shade, swings, and cleanliness. Conclusions The current study provides useful insights on park use with potentially important implications for increasing physical activity among children. Incorporating parents\u27 preferences into strategies for creating or modifying city parks will help to ensure that limited public resources are being targeted most effectively in support of children\u27s physical activity

Certified Professional Co-Active Coaches: Why They Enjoy Coaching

The evidence-base for the practice of coaching continues to flourish, despite the fact that very little is known about the practitioners (i.e. the coaches) themselves. It is of value to understand how coaches perceive their practice. Such information can be utilized to create a common knowledge-base about coaches that can be used, in turn, to track trends and forward research that evaluates coaching services. As the use of Co-Active coaching in facilitating behaviour change continues to rise it becomes important to learn more about Certified-Professional Co-Active Coaches (CPCC). Therefore, the purpose of this study is to evaluate what CPCCs enjoy about being coaches. These results were contained within a larger survey. A total of 390 CPCCs who were over 18 years of age, could read English, and had access to the Internet participated in the current study. Findings included: that witnessing clients change their lives; the sense of satisfaction and fulfillment from coaching; the collaborative relationship with clients; the autonomy and flexibility of the profession; and the gratification received from using their skill set were the main reasons CPCCs enjoyed coaching. This paper elaborates on these findings and makes suggestions for future research
