Master-planned communities in the United States as novel contexts for individual and population-level research.

It has long been known that social and physical environments can shape individual and population health, for better or worse. Master-planned communities (MPCs) in the US are custom-designed residential neighborhoods with defined boundaries planned and developed under a single, private owner or entity from their inception. Across the US, these vary greatly in scale ranging from 100 to over 50,000 homes, but broadly all provide residents with housing, infrastructure, landscaping, and purpose-built facilities to support socialization. Current research in the urban planning literature suggests that MPCs can influence the health of their residents. However, few studies have examined the use of MPCs as settings to conduct individual or population health research. In this paper, we examine the potential of MPCs as context for observational or intervention studies aimed at understanding individual and population-level health and well-being. We first summarize links between built and social environment and individual and population health research. Next, we describe the history of planned communities in the US. Then, we review specific features of MPCs related to governance, development, design, and social structure. We end by exploring how those specific features may lead to potential opportunities and challenges when using MPCs in health research. Through this discussion, we highlight MPCs as overlooked settings that may offer potential for collaborative, innovative, and socially engaged health research.

The use of notable protagonists in dermatology clinical cases: A quasi-randomized controlled trial.

BACKGROUND: Educators have attempted several methods to create more entertaining problem-based learning (PBL) experiences and more engaging PBL patients. To this end, our study compared the use of unique, memorable PBL characters with generic, unmemorable characters. METHODS: This prospective quasi-randomized controlled study utilized 476 university students. All subjects read ten medical cases that focused on dermatological illnesses. Cases were identical for everyone except subjects were allocated to have notable protagonists (NP) (i.e. cartoon characters or celebrities) or generic protagonists (GP) as patients in their cases. Surveys and tests were completed immediately, 7-10 days later, and 28-31 days later. RESULTS: There were no significant differences in post-test scores at any point between the groups. The only significant difference with regard to the subjective learning experience was for the entertainment level of the cases. The NP mean was 64.1±24.2, whereas the GP mean was 56.0±24.6 (t[444]=3.52, P=0.0005). The NP group also had a significantly higher proportion of subjects who researched dermatology/medicine topics after reading the cases (10.6% versus 2.7%, χ²(1,N=215)=5.47, P=0.02). CONCLUSIONS: The current study found that cases utilizing NPs, while still preserving the same educational value as cases using GPs, can provide a more entertaining learning experience and stimulate outside learning.

The effect of before school physical activity on child development: A study protocol to evaluate the Build Our Kids Success (BOKS) Program.

INTRODUCTION: Most childhood physical activity interventions focus on reducing childhood obesity with varying success, indicating that body mass index (BMI) may be a limited marker of health in children. To better understand overall childhood health and wellbeing, this study is investigating BOKS (Build Our Kids Success), an established ongoing before-school physical activity program, to evaluate students' physical health, mental health, cognitive capacity, and academic performance. DESIGN AND METHODS: The study is a non-randomized controlled trial with 26 elementary and middle schools in 3 Massachusetts communities, including first through eighth grade (aged 5-14) students, their parents, and teachers. Data collection is occurring during the 2015-2016 school year. Physical fitness is being assessed via 400m run and anthropometrics via height and weight measures (BMI). Psychosocial outcomes are being assessed via student, parent, and teacher survey and include nutrition, daily activities, emotional and relationship scales, bullying and victimization, vitality and energy, student engagement, stress, positive affect, self-efficacy and life satisfaction. Academic performance is reported by grades. Statistical methods include a psychometric evaluation of study measures, Pearson correlations, Student's t-tests, ANOVA/ANCOVA and multivariate linear regression including multilevel modeling analyses to account for the hierarchical organization of the data. DISCUSSION: This study is investigating a before school physical activity program on parameters of physical health, mental health, cognitive capacity, and academic performance by employing a novel triad approach, correlating the input of the child, parent, and teacher. Outcomes will evaluate the effectiveness of a before school physical activity program in elementary and middle schools and potentially provide valuable information for schools looking to institute innovative physical activity programs.

Creativity and psychopathology: a shared vulnerability model.

Creativity is considered a positive personal trait. However, highly creative people have demonstrated elevated risk for certain forms of psychopathology, including mood disorders, schizophrenia spectrum disorders, and alcoholism. A model of shared vulnerability explains the relation between creativity and psychopathology. This model, supported by recent findings from neuroscience and molecular genetics, suggests that the biological determinants conferring risk for psychopathology interact with protective cognitive factors to enhance creative ideation. Elements of shared vulnerability include cognitive disinhibition (which allows more stimuli into conscious awareness), an attentional style driven by novelty salience, and neural hyperconnectivity that may increase associations among disparate stimuli. These vulnerabilities interact with superior meta-cognitive protective factors, such as high IQ, increased working memory capacity, and enhanced cognitive flexibility, to enlarge the range and depth of stimuli available in conscious awareness to be manipulated and combined to form novel and original ideas.

Decreased latent inhibition is associated with increased creative achievement in high-functioning individuals.

Reductions in latent inhibition (LI), the capacity to screen from conscious awareness stimuli previously experienced as irrelevant, have been generally associated with the tendency towards psychosis. However, "failure" to screen out previously irrelevant stimuli might also hypothetically contribute to original thinking, particularly in combination with high IQ. Meta-analysis of two studies, conducted on youthful high-IQ samples. demonstrated that high lifetime creative achievers had significantly lower LI scores than low creative achievers (r(effect size) = .31, p = .0003, one-tailed). Eminent creative achievers (participants under 21 years who reported unusually high scores in a single domain of creative achievement) were 7 times more likely to have low rather than high LI scores, chi2 (1, N = 25) = 10.69, phi = .47. p = .003.
