Examining Community Engagement Research Strategies Used in Flint, Michigan: The Church Challenge.

Background: The ways in which researchers may need to adapt traditional community-based participatory research engagement strategies during ongoing community trauma are understudied. We describe our efforts to engage the Flint, Michigan community in community-based participatory research in the aftermath of the Flint Water Crisis.

Objectives: This manuscript describes 1) recruitment strategies selected before the Flint Water Crisis, 2) engagement lessons learned in the context of the Flint Water Crisis, and 3) barriers and facilitators encountered while engaging African American churches.

Torpor Does Not Influence Spatial Memory in Hibernating Golden-Mantled Ground Squirrels ().

AbstractMammalian hibernation in ground squirrels is characterized by periods of torpor wherein body temperature approaches ambient temperature and metabolism is reduced to as low as 1/100th of active rates. It is unclear how hibernation affects long-term spatial memory, as tremendous remodeling of neurons is associated with torpor use. Given the suspected links between remodeling and memory formation and retention, we examined long-term spatial memory retention throughout a hibernation season.

Exploring the Readiness of African-American Churches to Engage in a Community-Engaged Blood Pressure Reduction Research Study: Lessons Learned from the Church Challenge.

Introduction: The Transtheoretical Model (TTM) has been used to assess individual readiness for health behavior change. We describe our use of the TTM to assess organizational readiness of African-American churches to participate in the Church Challenge (CC) in Flint, Michigan; the processes of change that moved churches toward readiness for change; and lessons learned.

Methods: The CC was a faith-based, multilevel intervention to reduce chronic disease risk.

Implication of imposing fertilizer limitations on energy, agriculture, and land systems.

Since the 1950's, global fertilizer usage has increased by more than 800% resulting in detrimental impacts to the environment. The projected increase in crop production due to increasing demands for food, feed, biofuel, and other uses, may further increase fertilizer usage. Studies have examined achieving agricultural intensification in environmentally sustainable ways, however, they have not focused on the whole-system economic aspects of changes in fertilizer usage over the long term.

Deep mitigation of CO and non-CO greenhouse gases toward 1.5 °C and 2 °C futures.

Stabilizing climate change well below 2 °C and towards 1.5 °C requires comprehensive mitigation of all greenhouse gases (GHG), including both CO and non-CO GHG emissions. Here we incorporate the latest global non-CO emissions and mitigation data into a state-of-the-art integrated assessment model GCAM and examine 90 mitigation scenarios pairing different levels of CO and non-CO GHG abatement pathways.

Comparison of different mechanical chest compression devices in the alpine rescue setting: a randomized triple crossover experiment.

Background: Cardiopulmonary resuscitation in mountain environment is challenging. Continuous chest compressions during transport or hoist rescue are almost impossible without mechanical chest compression devices. Current evidence is predominantly based on studies conducted by urbane ambulance service.

The Climate Response to Emissions Reductions Due to COVID-19: Initial Results From CovidMIP.

Many nations responded to the corona virus disease-2019 (COVID-19) pandemic by restricting travel and other activities during 2020, resulting in temporarily reduced emissions of CO, other greenhouse gases and ozone and aerosol precursors. We present the initial results from a coordinated Intercomparison, CovidMIP, of Earth system model simulations which assess the impact on climate of these emissions reductions. 12 models performed multiple initial-condition ensembles to produce over 300 simulations spanning both initial condition and model structural uncertainty.

Global land use for 2015-2100 at 0.05° resolution under diverse socioeconomic and climate scenarios.

Global future land use (LU) is an important input for Earth system models for projecting Earth system dynamics and is critical for many modeling studies on future global change. Here we generated a new global gridded LU dataset using the Global Change Analysis Model (GCAM) and a land use spatial downscaling model, named Demeter, under the five Shared Socioeconomic Pathways (SSPs) and four Representative Concentration Pathways (RCPs) scenarios. Compared to existing similar datasets, the presented dataset has a higher spatial resolution (0.

The domestic and international implications of future climate for U.S. agriculture in GCAM.

Agricultural crop yields are susceptible to changes in future temperature, precipitation, and other Earth system factors. Future changes to these physical Earth system attributes and their effects on agricultural crop yields are highly uncertain. United States agricultural producers will be affected by such changes whether they occur domestically or internationally through international commodity markets.

The impact of interventions in the global land and agri-food sectors on Nature's Contributions to People and the UN Sustainable Development Goals.

Interlocked challenges of climate change, biodiversity loss, and land degradation require transformative interventions in the land management and food production sectors to reduce carbon emissions, strengthen adaptive capacity, and increase food security. However, deciding which interventions to pursue and understanding their relative co-benefits with and trade-offs against different social and environmental goals have been difficult without comparisons across a range of possible actions. This study examined 40 different options, implemented through land management, value chains, or risk management, for their relative impacts across 18 Nature's Contributions to People (NCPs) and the 17 Sustainable Development Goals (SDGs).

Tuberculous aortitis as a rare cause of aortobronchial fistula with massive haemoptysis: A case report.

Background: Aortobronchial fistula is a rare condition, which is difficult to diagnose. It is fatal if misdiagnosed or not well treated. Massive haemoptysis is usually the first common symptom.

Which practices co-deliver food security, climate change mitigation and adaptation, and combat land degradation and desertification?

There is a clear need for transformative change in the land management and food production sectors to address the global land challenges of climate change mitigation, climate change adaptation, combatting land degradation and desertification, and delivering food security (referred to hereafter as "land challenges"). We assess the potential for 40 practices to address these land challenges and find that: Nine options deliver medium to large benefits for all four land challenges. A further two options have no global estimates for adaptation, but have medium to large benefits for all other land challenges.

The moderating effect of psychological flexibility on event centrality in determining trauma outcomes.

Objective: Emerging research shows that event centrality, or the degree to which trauma is perceived as integral to one's worldviews and personal identity, has a substantial impact on trauma recovery. Given that high centrality fosters both distress and growth, additional research on potential moderators that could better distinguish the course of adjustment is needed. This study examined whether differences in psychological flexibility (or the ability to persist in a behavior despite urges to do otherwise) impacted posttraumatic stress symptoms (PTS) and perceived posttraumatic growth (PTG) as event centrality increased.

Key determinants of global land-use projections.

Land use is at the core of various sustainable development goals. Long-term climate foresight studies have structured their recent analyses around five socio-economic pathways (SSPs), with consistent storylines of future macroeconomic and societal developments; however, model quantification of these scenarios shows substantial heterogeneity in land-use projections. Here we build on a recently developed sensitivity approach to identify how future land use depends on six distinct socio-economic drivers (population, wealth, consumption preferences, agricultural productivity, land-use regulation, and trade) and their interactions.

A pathway of global food supply adaptation in a world with increasingly constrained groundwater.

Many of the world's major freshwater aquifers are being exploited unsustainably, with some projected to approach environmentally unsafe drawdown limits within the 21st century. Given that aquifer depletion tends to occur in important crop producing regions, the prospect of running dry poses a significant threat to global food security. Here we use the Global Change Assessment Model (GCAM) to explore the response of land use and agriculture sectors to severe constraints on global water resources.

Quantifying the biophysical and socioeconomic drivers of changes in forest and agricultural land in South and Southeast Asia.

South and Southeast Asia (SSEA) has been a hotspot for land use and land cover change (LULCC) in the past few decades. The identification and quantification of the drivers of LULCC are crucial for improving our understanding of LULCC trends. So far, the biophysical and socioeconomic drivers of forest change have not been quantified at the regional scale, particularly for SSEA.

Societal decisions about climate mitigation will have dramatic impacts on eutrophication in the 21 century.

Excessive nitrogen runoff leads to degraded water quality, harming human and ecosystem health. We examine the impact of changes in land use and land management for six combinations of socioeconomic pathways and climate outcomes, and find that societal choices will substantially impact riverine total nitrogen loading (+54% to -7%) for the continental United States by the end of the century. Regional impacts will be even larger.

Climate extremes, land-climate feedbacks and land-use forcing at 1.5°C.

This article investigates projected changes in temperature and water cycle extremes at 1.5°C of global warming, and highlights the role of land processes and land-use changes (LUCs) for these projections. We provide new comparisons of changes in climate at 1.

Caring for Children with Special Health Care Needs: Profiling Pediatricians and Their Health Care Resources.

Background and Objectives Pediatricians face numerous challenges in providing care for children with special health care needs (CSHCN). Few studies have described health care resources available to support pediatricians to care for CSHCN. This study investigated available resources to care for CSHCN and factors associated with having a greater proportion of CSHCN in practice.

Pediatricians' Comfort Level in Caring for Children With Special Health Care Needs.

Background: Few studies have investigated pediatrician attitudes about providing primary medical care for children with special health care needs. The objective of this study was to determine pediatrician perspectives on their comfort level in providing care and on where the medical home should be for children with chronic medical and developmental conditions.

Methods: Survey of pediatricians in California in 2014.

Assessing uncertainties in land cover projections.

Understanding uncertainties in land cover projections is critical to investigating land-based climate mitigation policies, assessing the potential of climate adaptation strategies and quantifying the impacts of land cover change on the climate system. Here, we identify and quantify uncertainties in global and European land cover projections over a diverse range of model types and scenarios, extending the analysis beyond the agro-economic models included in previous comparisons. The results from 75 simulations over 18 models are analysed and show a large range in land cover area projections, with the highest variability occurring in future cropland areas.

In Depth Proteome Analysis of Ripening Muscadine Grape Berry cv. Carlos Reveals Proteins Associated with Flavor and Aroma Compounds.

Ripening in nonclimacteric fruits such as grape involves complex chemical changes that have a profound influence on the accumulation of flavor and aroma compounds distinct to a particular grape genotype. In this study, proteome characterization of wine type bronze muscadine grape (Vitis rotundifolia cv. Carlos), primarily grown in the Southeastern United States was performed during berry ripening.

Hotspots of uncertainty in land-use and land-cover change projections: a global-scale model comparison.

Model-based global projections of future land-use and land-cover (LULC) change are frequently used in environmental assessments to study the impact of LULC change on environmental services and to provide decision support for policy. These projections are characterized by a high uncertainty in terms of quantity and allocation of projected changes, which can severely impact the results of environmental assessments. In this study, we identify hotspots of uncertainty, based on 43 simulations from 11 global-scale LULC change models representing a wide range of assumptions of future biophysical and socioeconomic conditions.
