Metabolic Potential of Microbial Communities in the Hypersaline Sediments of the Bonneville Salt Flats.

The Bonneville Salt Flats (BSF) appear to be entirely desolate when viewed from above, but they host rich microbial communities just below the surface salt crust. In this study, we investigated the metabolic potential of the BSF microbial ecosystem. The predicted and measured metabolic activities provide new insights into the ecosystem functions of evaporite landscapes and are an important analog for potential subsurface microbial ecosystems on ancient and modern Mars.

The Institutionalization of Kübler-Ross's Five-Stage Model of Death and Dying.

Kübler-Ross's five-stage model of death and dying-denial, anger, bargaining, depression, and acceptance-is one of the most popular theoretical models to come out of the 20th century. How did an obscure theory of the dying process come to dominate our understanding of emotional processes altogether? Building on previous work in the sociology of knowledge, I analyze the diffusion and institutionalization of Kübler-Ross's five-stage model in scientific and journalistic fields. Specifically, I analyze all 3216 citations of Kübler-Ross in the and the database using qualitative and quantitative text analysis.

Narratives and counter-narratives in religious responses to COVID-19: A computational text analysis.

Religious responses to COVID-19 as portrayed in a major news source raise the issue of conflict or cooperation between religious bodies and public health authorities. We compared articles in the New York Times relating to religion and COVID-19 with the COVID-19 statements posted on 63 faith-based organizations' web sites, and with the guidance documents published by the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO) specifically for religious bodies. We used computational text analysis to identify and compare sentiments and topics in the three bodies of text.

Geochemistry and Provenance of Springs in a Baja California Sur Mountain Catchment.

Fractured rock aquifers cover much of Earth's surface and are important mountain sites for groundwater recharge but are poorly understood. To investigate groundwater systematics of a fractured-dominated aquifer in Baja California Sur, Mexico, we examined the spatial patterns of aquifer recharge and connectivity using the geochemistry of springs. We evaluate a range of geochemical data within the context of two endmember hypotheses describing spatial recharge patterns and fracture connectivity.

Pain Catastrophizing and Pain Self-Efficacy Mediate Interdisciplinary Pain Rehabilitation Program Outcomes at Posttreatment and Follow-Up.

Background: Decreasing pain catastrophizing and improving self-efficacy to self-manage chronic pain symptoms are important treatment targets in the context of interdisciplinary pain rehabilitation. Greater pain catastrophizing has been shown to be associated with greater impact of pain symptoms on functioning; conversely, greater pain self-efficacy has been associated with lower pain intensity and lower levels of disability.

Objective: To prospectively evaluate interdisciplinary pain rehabilitation outcomes, as well as to evaluate the mediating effects of both pain catastrophizing and pain self-efficacy on outcome.
