SOCIAL CAPITAL AND HOUSEHOLD INCOME DISTRIBUTIONS: EVIDENCE FROM MICHIGAN AND ILLINOIS
Social capital is a resource increasingly recognized as having important economic and social consequences. Robison and Siles (1999) examined some of these consequences at the U.S. state level and this study extends their efforts. Their 1999 study found important connections between the distributions of social capital and the distributions of household incomes. This study asks if the relationships between social capital and household incomes discovered at the state level are also present at the community level.Consumer/Household Economics, Institutional and Behavioral Economics,
Assessing Photoreceptor Structure Associated with Ellipsoid Zone Disruptions Visualized with Optical Coherence Tomography
Purpose: To compare images of photoreceptor layer disruptions obtained with optical coherence tomography (OCT) and adaptive optics scanning light ophthalmoscopy (AOSLO) in a variety of pathologic states.Methods: Five subjects with photoreceptor ellipsoid zone disruption as per OCT and clinical diagnoses of closed-globe blunt ocular trauma (n = 2), macular telangiectasia type 2 (n = 1), blue-cone monochromacy (n = 1), or cone-rod dystrophy (n = 1) were included. Images were acquired within and around photoreceptor lesions using spectral domain OCT, confocal AOSLO, and split-detector AOSLO.Results: There were substantial differences in the extent and appearance of the photoreceptor mosaic as revealed by confocal AOSLO, split-detector AOSLO, and spectral domain OCT en face view of the ellipsoid zone.Conclusion: Clinically available spectral domain OCT, viewed en face or as B-scan, may lead to misinterpretation of photoreceptor anatomy in a variety of diseases and injuries. This was demonstrated using split-detector AOSLO to reveal substantial populations of photoreceptors in areas of no, low, or ambiguous ellipsoid zone reflectivity with en face OCT and confocal AOSLO. Although it is unclear if these photoreceptors are functional, their presence offers hope for therapeutic strategies aimed at preserving or restoring photoreceptor function
Assessing Wellness Needs of Breast Cancer Survivors in Vermont
Background: • In Vermont, 500 breast cancer diagnoses are made annually. • As of 2005, epidemiological data suggest that as many as 7,000 breast cancer survivors were living in VT. • Dragonheart Vermont’s “Survivorship NOW”4 initiative aims to bridge the gap between treatment and recovery. • A literature review, including the Taking Charge program and a survivor needs assessment done by Dr. Geller, supported conducting a needs assessment in three areas: exercise, nutrition, and emotional support. • UVM COM paired with Dragonheart Vermont’s “Survivorship NOW” initiative to determine how to best address these needs.https://scholarworks.uvm.edu/comphp_gallery/1073/thumbnail.jp
The Escherichia coli RutR transcription factor binds at targets within genes as well as intergenic regions.
The Escherichia coli RutR protein is the master regulator of genes involved in pyrimidine catabolism. Here we have used chromatin immunoprecipitation in combination with DNA microarrays to measure the binding of RutR across the chromosome of exponentially growing E. coli cells. Twenty RutR-binding targets were identified and analysis of these targets generated a DNA consensus logo for RutR binding. Complementary in vitro binding assays showed high-affinity RutR binding to 16 of the 20 targets, with the four low-affinity RutR targets lacking predicted key binding determinants. Surprisingly, most of the DNA targets for RutR are located within coding segments of the genome and appear to have little or no effect on transcript levels in the conditions tested. This contrasts sharply with other E. coli transcription factors whose binding sites are primarily located in intergenic regions. We suggest that either RutR has yet undiscovered function or that evolution has been slow to eliminate non-functional DNA sites for RutR because they do not have an adverse effect on cell fitness

Abnormal returns, risk, and financial statement data: The case of the Iraqi invasion of Kuwait
This paper examines abnormal returns and changes in risk for transportation firms immediately around the Iraqi invasion of Kuwait. Further, it tests whether the variation in the abnormal returns can be explained cross-sectionally with standard financial and industry-descriptive variables. The results indicate that transportation firms suffered a −2.09% abnormal return and increases in unsystematic risk. The cross sectional regression explains 31% of the variation in the abnormal returns, with firm size, liquidity, leverage, percentage of sales to the Department of Defense, and dummy variables denoting firms producing recreational vehicles or owning oil-producing subsidiaries contributing significantly to the regression
Implementation of World Health Organization Integrated Management of Childhood Illnesses (IMCI) Guidelines for the Assessment of Pneumonia in the Under 5s in Rural Malawi
The Cooking and Pneumonia Study (CAPS) is a pragmatic cluster-level randomized controlled trial of the effect of an advanced cookstove intervention on pneumonia in children under the age of 5 years (under 5s) in Malawi (www.capstudy.org). The primary outcome of the trial is the incidence of pneumonia during a two-year follow-up period, as diagnosed by healthcare providers who are using the World Health Organization (WHO) integrated management of childhood illnesses (IMCI) pneumonia assessment protocol and who are blinded to the trial arms. We evaluated the quality of pneumonia assessment in under 5s in this setting via a cross-sectional study of provider-patient encounters at nine outpatient clinics located within the catchment area of 150 village-level clusters enrolled in the trial across the two study locations of Chikhwawa and Karonga, Malawi, between May and June 2015 using the IMCI guidelines as a benchmark. Data were collected using a key equipment checklist, an IMCI pneumonia knowledge test, and a clinical evaluation checklist. The median number of key equipment items available was 6 (range 4 to 7) out of a possible 7. The median score on the IMCI pneumonia knowledge test among 23 clinicians was 75% (range 60% to 89%). Among a total of 176 consultations performed by 15 clinicians, a median of 9 (range 3 to 13) out of 13 clinical evaluation tasks were performed. Overall, the clinicians were adequately equipped for the assessment of sick children, had good knowledge of the IMCI guidelines, and conducted largely thorough clinical evaluations. We recommend the simple pragmatic approach to quality assurance described herein for similar studies conducted in challenging research settings
Review of The Internet Companion: A Beginner's Guide to Global Networking, by Tracy LaQuey (with Jeanne C. Ryer)
LaQuey and Ryer and have put together a guide to networking that almost reads like a novel. The text, written in nontechnical language, is organized to create and sustain interest in networking on the part of the user. Included are simple, somewhat comical diagrams that clarify concepts and systems while making a neophyte feel comfortable with terms like "Serial Line Internet Protocol." Helping to convey the authors' own excitement over networking are numerous sidebars with text taken from various sources that provide anecdotal evidence of the richness and power of the virtual culture
Mainstreaming marine biodiversity into the SDGs: The role of other effective area-based conservation measures (SDG 14.5)
This article explores the concept of “other effective area-based conservation measures” (OECMs) in the context of the UN Convention on Biological Diversity (CBD) Aichi Biodiversity Target 11 on marine protected areas and OECMs and its linkages to the Sustainable Development Goals (SDGs). It argues that mainstreaming biodiversity through CBD Aichi Biodiversity Targets’ implementation into the SDGs can contribute to a more systemic and comprehensive implementation of SDG 14.5 on conservation of at least 10% of marine and coastal areas. It argues that OECMs can complement MPAs and contribute to ecologically representative and effectively managed marine protected areas systems integrated into broader governance systems such as marine spatial planning. Selected global and local sectoral conservation measures are therefore highlighted in this analysis as potential forms of OECMs. At the local level, a case study of ecologically or biologically significant marine areas managed as locally managed marine areas (LMMAs) in Mozambique is discussed. This case study explores how multiple-use LMMAs, which respond to short-term fisher's needs and targeted biodiversity conservation, could contribute to the achievement of specific SDGs on food security, poverty elimination and resilient ecosystems if properly supported by long-term investments, strong institutions and integrated oceans management
