Texan City magazine health news : a content analysis

City magazines have a powerful role in convincing readers to take proactive health measures, however they rarely take advantage of their capacity to set their communities' public agendas. This study considered the health content in five city magazines in Texas: Austin Monthly, D Magazine, Fort Worth, Texas Magazine, Houstonia, and San Antonio Magazine. Using agenda building, agenda-setting, and second-level agenda-setting, this research quantitatively analyzed 169 health articles published in 2018 on the five magazines' websites for how the publications presented health news. The core findings of this research included: the overall agenda was actionable health, the city magazines were more than three times more likely to cite an indirect source than a human, and that salient story elements promoted the historical status quo of city magazines and not the health agenda or health literacy. The most prevalent story topic was nutrition/fitness, occurring in the majority of the articles. The core of my research was to question whether these publications were publishing health content that reflected their cities' health profiles. While some magazines, such as Houstonia and Fort Worth, Texas Magazine did better than others, all of the city magazines could improve.by Catherine WendlandtIncludes bibliographical reference

Mass transfer in the lower crust: Evidence for incipient melt assisted flow along grain boundaries in the deep arc granulites of Fiordland, New Zealand

Knowledge of mass transfer is critical in improving our understanding of crustal evolution, however mass transfer mechanisms are debated, especially in arc environments. The Pembroke Granulite is a gabbroic gneiss, passively exhumed from depths of >45 km from the arc root of Fiordland, New Zealand. Here, enstatite and diopside grains are replaced by coronas of pargasite and quartz, which may be asymmetric, recording hydration of the gabbroic gneiss. The coronas contain microstructures indicative of the former presence of melt, supported by pseudosection modeling consistent with the reaction having occurred near the solidus of the rock (630–710°C, 8.8–12.4 kbar). Homogeneous mineral chemistry in reaction products indicates an open system, despite limited metasomatism at the hand sample scale. We propose the partial replacement microstructures are a result of a reaction involving an externally derived hydrous, silicate melt and the relatively anhydrous, high-grade assemblage. Trace element mapping reveals a correlation between reaction microstructure development and bands of high-Sr plagioclase, recording pathways of the reactant melt along grain boundaries. Replacement microstructures record pathways of diffuse porous melt flow at a kilometer scale within the lower crust, which was assisted by small proportions of incipient melt providing a permeable network. This work recognizes melt flux through the lower crust in the absence of significant metasomatism, which may be more common than is currently recognized. As similar microstructures are found elsewhere within the exposed Fiordland lower crustal arc rocks, mass transfer of melt by diffuse porous flow may have fluxed an area >10,000 km2
