The Value of Balanced Growth for Transportation

The Ohio Balanced Growth Program is a voluntary, locally-driven, incentive-driven program which aims to encourage compact, nodal development patterns. The Ohio Department of Transportation provided support for this research to evaluate potential links between Balanced Growth-type policy, land use and development patterns, and transportation benefits. A literature review was completed to understand the existing body of knowledge regarding the connection between policy, land use, and transportation. This included a scan of Balanced Growth-type programs across the US. Twenty-six US Metropolitan Statistical Areas (MSAs) were selected and reviewed for general geographic and policy characteristics. Land use and transportation outcome data were examined via scatterplot and linear regression across all of the MSAs. The results were evaluated broadly in light of policy frameworks in effect in each MSA, by categorizing land use policy into “tiers” based on voluntary vs. mandatory provisions, and applicability to private and public investment. Finally, a policy review was completed to understand the potential benefits of policy change at the state, regional, and local agency levels. Significant relationships were found between land use patterns, measured in terms of a sprawl composite index, and transportation outcomes for freeway lane miles, hours of delay, vehicle miles traveled, emissions, and safety. MSAs with “Tier 3” policies (mandatory, rigorous policy affecting both public and private investment) clustered together on both axes (transportation outcomes and sprawl); and MSAs within states clustered together along the sprawl score axis. Otherwise, there was no apparent pattern in the location of policy tiers along either the transportation or land use axes. Possible alternative explanations that could be evaluated in the future include overall transportation investment levels; inter-state and inter-regional travel demand; size and shape of the MSA; and market, economic and social factors. Conclusions included policy recommendations for ODOT in supporting compact, nodal development at the local, regional and state levels. Future study recommendations include pursuing future data collection, monitoring and evaluation over time

School-based Interventions to Reduce Sedentary Behaviour in Children: A Systematic Review

Prolonged, uninterrupted periods of sedentary time may be associated with increased risk of Type II diabetes, cardiovascular disease and all-cause mortality even if the minimum recommended levels of daily physical activity are achieved. It is reported that children spend approximately 80% of their day engaged in sedentary behaviours. Since children spend a large portion of their waking time at school, school-based interventions targeting excessive or interrupted periods of sedentary time have been investigated in a number of studies. However, results of the effectiveness of studies to-date have been inconsistent. Aim: To conduct a systematic review to evaluate the effectiveness of school-based interventions designed to reduce sedentary behaviour on objectively measured sedentary time in children. Methods: Five electronic databases were searched to retrieve peer-reviewed studies published in English up to and including August 2015. Studies that reported objectively measured sedentary time before and after a school-based intervention to reduce sedentary time were included in the review. Risk of bias was assessed using the Cochrane Collaboration method. Results: Our search identified eleven papers reporting eight interventions. Studies focused on the physical environment, the curriculum, individual in-class activities, homework activities or a combination of these strategies. Three studies reported decreases in sedentary time following intervention. Study follow-up periods ranged from immediately post-intervention to 12 months. None of the studies were judged to have a low risk of bias. Conclusions: Multicomponent interventions which also include the use of standing desks may be an effective method for reducing children’s sedentary time in a school-based intervention. However, longer term trials are needed to determine the sustained effectiveness of such interventions on children’s sedentary time

Introductory programming: a systematic literature review

As computing becomes a mainstream discipline embedded in the school curriculum and acts as an enabler for an increasing range of academic disciplines in higher education, the literature on introductory programming is growing. Although there have been several reviews that focus on specific aspects of introductory programming, there has been no broad overview of the literature exploring recent trends across the breadth of introductory programming. This paper is the report of an ITiCSE working group that conducted a systematic review in order to gain an overview of the introductory programming literature. Partitioning the literature into papers addressing the student, teaching, the curriculum, and assessment, we explore trends, highlight advances in knowledge over the past 15 years, and indicate possible directions for future research

Concentration or representation : the struggle for popular sovereignty

There is a tension in the notion of popular sovereignty, and the notion of democracy associated with it, that is both older than our terms for these notions themselves and more fundamental than the apparently consensual way we tend to use them today. After a review of the competing conceptions of 'the people' that underlie two very different understandings of democracy, this article will defend what might be called a 'neo-Jacobin' commitment to popular sovereignty, understood as the formulation and imposition of a shared political will. A people's egalitarian capacity to concentrate both its collective intelligence and force, from this perspective, takes priority over concerns about how best to represent the full variety of positions and interests that differentiate and divide a community

Bodyweight Perceptions among Texas Women: The Effects of Religion, Race/Ethnicity, and Citizenship Status

Despite previous work exploring linkages between religious participation and health, little research has looked at the role of religion in affecting bodyweight perceptions. Using the theoretical model developed by Levin et al. (Sociol Q 36(1):157–173, 1995) on the multidimensionality of religious participation, we develop several hypotheses and test them by using data from the 2004 Survey of Texas Adults. We estimate multinomial logistic regression models to determine the relative risk of women perceiving themselves as overweight. Results indicate that religious attendance lowers risk of women perceiving themselves as very overweight. Citizenship status was an important factor for Latinas, with noncitizens being less likely to see themselves as overweight. We also test interaction effects between religion and race. Religious attendance and prayer have a moderating effect among Latina non-citizens so that among these women, attendance and prayer intensify perceptions of feeling less overweight when compared to their white counterparts. Among African American women, the effect of increased church attendance leads to perceptions of being overweight. Prayer is also a correlate of overweight perceptions but only among African American women. We close with a discussion that highlights key implications from our findings, note study limitations, and several promising avenues for future research

Biomarkers of environmental enteric dysfunction and adverse birth outcomes: an observational study among pregnant women living with HIV in Tanzania

BACKGROUND: Environmental enteric dysfunction (EED) may contribute to adverse birth outcomes in low-resource settings. We examined the associations of EED biomarkers with birth outcomes in pregnant women living with human immunodeficiency virus in Dar es Salaam, Tanzania. METHODS: We performed a cohort study of 706 HIV-infected pregnant women. Maternal serum samples collected at 32 weeks gestation were analyzed for markers of EED (anti-flagellin and anti-LPS immunoglobulins, intestinal fatty acid-binding protein [I-FABP] and soluble CD14), systemic inflammation (C-reactive protein and α1-acid glycoprotein [AGP]), and growth hormone resistance (insulin-like growth factor 1 [IGF-1] and fibroblast growth factor 21 [FGF21]. Associations of biomarkers categorized into quartiles with birth outcomes (birthweight, gestational duration, birthweight-for-gestational age, and stillbirth) were assessed using linear and log-binomial regression models adjusted for multiple sociodemographic and clinical variables. FINDINGS: Maternal EED biomarkers were not significantly associated with birthweight, gestation duration, or birthweight-for-gestational age. However, higher quintiles of I-FABP concentrations were associated with greater risk of stillbirth (ptrend=0·02). Higher AGP was associated with lower birthweight and was associated with increased risk of small-for-gestational age births. Higher IGF-1 was associated with higher birthweight and birthweight-for-gestational age while higher FGF21 was associated with shorter gestation and higher risk of preterm birth. INTERPRETATION: Maternal biomarkers of EED, systemic inflammation, and growth hormones were differentially associated with birth outcomes. Biomarkers of EED may be useful to identify pregnant women at risk of adverse birth outcomes, but further research is needed to confirm these findings and elucidate biological mechanisms.Research Pilot & Feasibility Grant - Nutrition Obesity Research Center at Harvard (NORCH); R21DK123636 - National Institutes of HealthPublished versio
