How Does the Rural Food Environment Affect Rural Childhood Obesity?
Objective: Assess the impact of the rural food environment on the eating behaviors and BMI of rural low-income children. Method: Statewide (Maine, 2009) household survey of parents of children on Medicaid (n=1722), oversampled in six rural communities, resulting in n=272 for six target communities. Food environment measured using modified Nutrition Environment Measures Survey in Stores (NEMS-S) for 46 retail food outlets. Multi-variate analysis assessed factors affecting home food environment, child\u27s eating behavior and BMI. Results: Home food behaviors (how often: family eats together, child eats breakfast, vegetables served) and parent food consumption were significantly associated with children\u27s healthy eating behaviors. The only significant predictor of childhood obesity was parent eating behavior. We observed several alternative strategies such as hunting, gathering and buying from local farmers. Parents who drove over 20 miles to shop were found to shop at stores with higher NEMS scores as compared to parents who drove shorter distances.Conclusion: Defining and identifying food deserts is not a promising approach to measuring the rural food environment due to long distance trips, careful price shopping, and local, alternative strategies. Strategies to place healthier food in the home should be combined with interventions directed at parents\u27 and families\u27 eating behaviors
Rural Children Experience Different Rates of Mental Health Diagnosis and Treatment
Research indicates that privately insured, rural adults have lower use of office-based mental health services, but higher use of prescription medicines than their urban counterparts. Patterns for rural children may be different from urban children because of the limited supply of pediatric mental health providers in rural areas, which may lead to reduced access and lower use of mental health services in rural areas versus urban. Using data on children ages 5-17 from the 2002-2008 of the Medical Expenditure Panel Survey, researchers from the Maine Rural Health Research Center find that rural children are significantly less likely to be diagnosed and treated for non-ADHD mental health problems than urban children and are less likely to receive mental health counseling. The rural-urban difference is greatest among those children scoring in the “possible impairment” range on the Columbia Impairment Scale
Health Insurance Profile Indicates Need to Expand Coverage in Rural Areas
Key Findings: A greater percentage of rural residents than urban residents are uninsured, especially those living in remote areas Among adults over age 50, uninsured rates are highest in the most remote rural places Compared to urban adults, rural adults are less likely to be in employment situations where private coverage is offered
Patterns of Care for Rural and Urban Children with Mental Health Problems
Introduction
Research indicates that privately insured, rural adults have lower use of office-based mental health services, but higher use of prescription medicines than their urban counterparts. Similar studies for rural children have been limited to specific populations, diagnoses, or to single states. Patterns for rural children may be different than those of urban children and adults generally because of their high enrollment in Medicaid and the State Children\u27s Health Insurance Program, which tend to have more generous behavioral health benefits than private coverage and may equalize rural-urban treatment patterns. On the other hand, the more limited supply of specialty mental health providers in rural areas, particularly for children, could lead to lack of access and lower utilization of some types of mental health services in rural areas versus urban.
Methods
Using data on children ages 5-17 from the 2002-2008 Medical Expenditure Panel Survey, this study examines two research questions: 1) do patterns of children\u27s mental health diagnosis and service use (e.g., office visits and psychotropic medications) differ by rural-urban residence? and 2) what is the effect of income and insurance type on use of mental health services?
Findings
Controlling for demographic and risk factors, rural children are as likely as urban children to have an attention deficit or hyperactivity disorder (ADHD) diagnosis and less likely to have any other type of psychiatric diagnosis. Initially observed higher prevalence of mental health diagnoses among rural children is explained by underlying differences in demographic characteristics and risk factors, such as higher rates of poverty, public coverage, mental health impairment, and lower prevalence of minorities. Rural children with the highest mental health need are no more or less likely to be diagnosed or treated for mental health conditions. However, among those with a possible impairment, rural children are less likely to be diagnosed with a psychiatric illness other than ADHD and are less likely to receive counseling
Suited for Success? : Suits, Status, and Hybrid Masculinity
This document is the Accepted Manuscript version. The final, definitive version of this paper has been published in Men and Masculinities, March 2017, doi: https://doi.org/10.1177/1097184X17696193, published by SAGE Publishing, All rights reserved.This article analyzes the sartorial biographies of four Canadian men to explore how the suit is understood and embodied in everyday life. Each of these men varied in their subject positions—body shape, ethnicity, age, and gender identity—which allowed us to look at the influence of men’s intersectional identities on their relationship with their suits. The men in our research all understood the suit according to its most common representation in popular culture: a symbol of hegemonic masculinity. While they wore the suit to embody hegemonic masculine configurations of practice—power, status, and rationality—most of these men were simultaneously marginalized by the gender hierarchy. We explain this disjuncture by using the concept of hybrid masculinity and illustrate that changes in the style of hegemonic masculinity leave its substance intact. Our findings expand thinking about hybrid masculinity by revealing the ways subordinated masculinities appropriate and reinforce hegemonic masculinity.Peer reviewe
Rosetta-Alice Observations of Exospheric Hydrogen and Oxygen on Mars
The European Space Agency's Rosetta spacecraft, en route to a 2014 encounter
with comet 67P/Churyumov-Gerasimenko, made a gravity assist swing-by of Mars on
25 February 2007, closest approach being at 01:54UT. The Alice instrument on
board Rosetta, a lightweight far-ultraviolet imaging spectrograph optimized for
in situ cometary spectroscopy in the 750-2000 A spectral band, was used to
study the daytime Mars upper atmosphere including emissions from exospheric
hydrogen and oxygen. Offset pointing, obtained five hours before closest
approach, enabled us to detect and map the HI Lyman-alpha and Lyman-beta
emissions from exospheric hydrogen out beyond 30,000 km from the planet's
center. These data are fit with a Chamberlain exospheric model from which we
derive the hydrogen density at the 200 km exobase and the H escape flux. The
results are comparable to those found from the the Ultraviolet Spectrometer
experiment on the Mariner 6 and 7 fly-bys of Mars in 1969. Atomic oxygen
emission at 1304 A is detected at altitudes of 400 to 1000 km above the limb
during limb scans shortly after closest approach. However, the derived oxygen
scale height is not consistent with recent models of oxygen escape based on the
production of suprathermal oxygen atoms by the dissociative recombination of
O2+.Comment: 17 pages, 8 figures, accepted for publication in Icaru
A dual role for prediction error in associative learning
Confronted with a rich sensory environment, the brain must learn
statistical regularities across sensory domains to construct causal
models of the world. Here, we used functional magnetic resonance
imaging and dynamic causal modeling (DCM) to furnish neurophysiological
evidence that statistical associations are learnt, even when
task-irrelevant. Subjects performed an audio-visual target-detection
task while being exposed to distractor stimuli. Unknown to them,
auditory distractors predicted the presence or absence of subsequent
visual distractors. We modeled incidental learning of these associations
using a Rescorla--Wagner (RW) model. Activity in primary visual
cortex and putamen reflected learning-dependent surprise: these areas
responded progressively more to unpredicted, and progressively less
to predicted visual stimuli. Critically, this prediction-error response
was observed even when the absence of a visual stimulus was
surprising. We investigated the underlying mechanism by embedding
the RW model into a DCM to show that auditory to visual connectivity
changed significantly over time as a function of prediction error. Thus,
consistent with predictive coding models of perception, associative
learning is mediated by prediction-error dependent changes in connectivity.
These results posit a dual role for prediction-error in encoding
surprise and driving associative plasticity
