Public Discourses about Teenage Pregnancy: Disruption, Restoration, and Ideology

Two recent incidents in the United States generated a wealth of public discourses about a particular reproductive health issue: adolescent childbearing. As the media, political pundits, and private citizens pondered the meaning of these events, they expressed viewpoints, explanations, and possible solutions in mass-mediated outlets. We examined the discourses communicated in such outlets to understand how public discussion of teenage pregnancy reveals ideological assumptions about reproductive health, ideal family forms, and the expected life course

“The Secret is Out!” Supporting Weight Loss through Online Interaction

This chapter provides a case study of how social support is communicated through online discussion on a weight loss community website. The site has many features including member profiles, journals, discussion boards, exercise and food trackers, and charts to help members keep track of their weight loss efforts. Members set goals, write journal entries, comment on one another’s journals, upload photos, join groups and challenges, and concerns issues related to diet, exercise, lifestyle changes, and other issues in their lives. Through analysis of journal entries and discussion forum comments, we discern how members demonstrate and respond to social support with one another. We also investigate the ways in which features of the online discussion help people communicate support. This study has implications for facilitators or web designers who want to create online spaces that foster supportive communication, particularly related to health concerns

A type catalog of fossil invertebrates (Mollusca: Actinoceratoidea, Bactritoidea, Endoceratoidea and Nautiloidea) in the Yale Peabody Museum

Type material for 220 nominal species of fossil actinoceratoids, bactritoids, endoceratoids and nautiloids are in the Invertebrate Paleontology Collections of Yale University\u27s Peabody Museum of Natural History. Primary types for 158 nominal species include 133 holotypes, 64 syntypes (representing 18 nominal species), one lectotype and two neotypes. Secondary types for 22 nominal species include 90 paratypes. Tertiary types of 98 nominal species include 159 hypotypes. Most types are from Coahuila (Mexico), Newfoundland, New York State and Quebec and have been described by R.H. Flower, A.F. Foerste, J. Hall and A.K. Miller

A Sr-Rich Star on the Main Sequence of Omega Centauri

Abundance ratios relative to iron for carbon, nitrogen, strontium and barium are presented for a metal-rich main sequence star ([Fe/H]=--0.74) in the globular cluster omega Centauri. This star, designated 2015448, shows depleted carbon and solar nitrogen, but more interestingly, shows an enhanced abundance ratio of strontium [Sr/Fe] ~ 1.6 dex, while the barium abundance ratio is [Ba/Fe]<0.6 dex. At this metallicity one usually sees strontium and barium abundance ratios that are roughly equal. Possible formation scenarios of this peculiar object are considered.Comment: 13 pages, 3 figures.

Abundances on the Main Sequence of Omega Centauri

Abundance ratios of carbon, nitrogen and strontium relative to iron, calculated using spectrum synthesis techniques, are given for a sample of main sequence and turnoff stars that belong to the globular cluster omega Centauri. The variations of carbon, nitrogen and/or strontium show several different abundance patterns as a function of [Fe/H]. The source of the enhancements/depletions in carbon, nitrogen and/or strontium may be enrichment from asymptotic giant branch stars of low (1--3 solar masses) and intermediate (3--8 solar masses) mass. Massive rotating stars which produce excess nitrogen without carbon and oxygen overabundances may also play a role. These abundances enable different contributors to be considered and incorporated into the evolutionary picture of omega Cen.Comment: 43 Pages, 13 Figures. Accepted for publication in Ap

Ocean acidification and human health

The ocean provides resources key to human health and well-being, including food, oxygen, livelihoods, blue spaces, and medicines. The global threat to these resources posed by accelerating ocean acidification is becoming increasingly evident as the world’s oceans absorb carbon dioxide emissions. While ocean acidification was initially perceived as a threat only to the marine realm, here we argue that it is also an emerging human health issue. Specifically, we explore how ocean acidification affects the quantity and quality of resources key to human health and well-being in the context of: (1) malnutrition and poisoning, (2) respiratory issues, (3) mental health impacts, and (4) development of medical resources. We explore mitigation and adaptation management strategies that can be implemented to strengthen the capacity of acidifying oceans to continue providing human health benefits. Importantly, we emphasize that the cost of such actions will be dependent upon the socioeconomic context; specifically, costs will likely be greater for socioeconomically disadvantaged populations, exacerbating the current inequitable distribution of environmental and human health challenges. Given the scale of ocean acidification impacts on human health and well-being, recognizing and researching these complexities may allow the adaptation of management such that not only are the harms to human health reduced but the benefits enhanced.publishedVersio

Design of the Subpopulations and Intermediate Outcome Measures in COPD (SPIROMICS) AIR Study.

IntroductionPopulation-based epidemiological evidence suggests that exposure to ambient air pollutants increases hospitalisations and mortality from chronic obstructive pulmonary disease (COPD), but less is known about the impact of exposure to air pollutants on patient-reported outcomes, morbidity and progression of COPD.Methods and analysisThe Subpopulations and Intermediate Outcome Measures in COPD (SPIROMICS) Air Pollution Study (SPIROMICS AIR) was initiated in 2013 to investigate the relation between individual-level estimates of short-term and long-term air pollution exposures, day-to-day symptom variability and disease progression in individuals with COPD. SPIROMICS AIR builds on a multicentre study of smokers with COPD, supplementing it with state-of-the-art air pollution exposure assessments of fine particulate matter, oxides of nitrogen, ozone, sulfur dioxide and black carbon. In the parent study, approximately 3000 smokers with and without airflow obstruction are being followed for up to 3 years for the identification of intermediate biomarkers which predict disease progression. Subcohorts undergo daily symptom monitoring using comprehensive daily diaries. The air monitoring and modelling methods employed in SPIROMICS AIR will provide estimates of individual exposure that incorporate residence-specific infiltration characteristics and participant-specific time-activity patterns. The overarching study aim is to understand the health effects of short-term and long-term exposures to air pollution on COPD morbidity, including exacerbation risk, patient-reported outcomes and disease progression.Ethics and disseminationThe institutional review boards of all the participating institutions approved the study protocols. The results of the trial will be presented at national and international meetings and published in peer-reviewed journals
