7 Things Churches Can Do to Make Queer People Feel Welcome

For as long as I can remember, the church, for me, has been a place characterized by shame and hurt. I remember Christian high school friends telling me that I would go to hell for being Queer. I remember hearing sermons from televangelists about the evils of homosexuality, and church leaders pressuring youth leaders to cast out their Queer members. I\u27ve heard more talk of love the sinner, hate the sin, and God didn\u27t make gay, than anyone should, and I\u27ve even received personalized hate mail declaring that God hates dykes. [excerpt

The American Preparedness Project: Where the US Public Stands in 2015

The American Preparedness Project was launched by the National Center for Disaster Preparedness (NCDP) in 2002, in the aftermath of the 9/11 attacks in order to survey public perceptions and opinions on disaster preparedness and to acknowledge that a comprehensive understanding of the concerns of individuals and families is critical to emergency planning efforts on all levels. Characterizing such trends is critical because in order to develop effective disaster plans, as well as a sustainable long term disaster preparedness strategy, people need to be confident in (a) the reliability of information from official sources, (b) the capacity of government to perform effectively in a crisis and (c) the capability of response systems, particularly health systems and first responders.The major findings of the 2015 American Preparedness Project are presented in the Key Findings section of this report. The American Preparedness Project survey has been administered eight times since the launch of the project in 2002. Although the content of the questionnaire has changed over time to reflect the changing disaster landscape, a select set of questions has been asked in every iteration of the survey in order to capture changes over time.These questions are presented in the National Trends Since 9/11 section of this report and capture national confidence in household and community preparedness, response systems, and leadership. Following the overview of national trends over time, the report highlights findings from the current survey (see Key Findings in 2015) across the domains of General Preparedness, Natural Disasters and Climate Change,Terrorism, and Children in Disasters. The report concludes with Recommendations for improving national, community and household-level preparedness

Children in Disasters: Do Americans Feel Prepared? A National Survey

This study was led by the National Center for Disaster Preparedness (NCDP) at Columbia University’s Earth Institute on behalf of the Resilient Children/Resilient Communities (RCRC) Initiative, in partnership with Save the Children with funding from GSK.The purpose of the study was to learn more about people’s opinions and attitudes toward disaster preparedness with a focus on children in disasters.The national survey of American households was conducted in December 2015. Eligible participants were 18 years of age or older, and included participants, with or without children, in their household. Many of the families surveyed had children in a K-12 school or in daycare

Differential susceptibility of C57BL/6NCr and B6.Cg-Ptprca mice to commensal bacteria after whole body irradiation in translational bone marrow transplant studies

Abstract Background The mouse is an important and widely utilized animal model for bone marrow transplant (BMT) translational studies. Here, we document the course of an unexpected increase in mortality of congenic mice that underwent BMT. Methods Thirty five BMTs were analyzed for survival differences utilizing the Log Rank test. Affected animals were evaluated by physical examination, necropsy, histopathology, serology for antibodies to infectious disease, and bacterial cultures. Results Severe bacteremia was identified as the main cause of death. Gastrointestinal (GI) damage was observed in histopathology. The bacteremia was most likely caused by the translocation of bacteria from the GI tract and immunosuppression caused by the myeloablative irradiation. Variability in groups of animals affected was caused by increased levels of gamma and X-ray radiation and the differing sensitivity of the two nearly genetically identical mouse strains used in the studies. Conclusion Our retrospective analysis of thirty five murine BMTs performed in three different laboratories, identified C57BL/6NCr (Ly5.1) as being more radiation sensitive than B6.Cg-Ptprca/NCr (Ly5.2). This is the first report documenting a measurable difference in radiation sensitivity and its effects between an inbred strain of mice and its congenic counterpart eventually succumbing to sepsis after BMT.http://deepblue.lib.umich.edu/bitstream/2027.42/112743/1/12967_2007_Article_240.pd

Frequency drift in MR spectroscopy at 3T

Purpose: Heating of gradient coils and passive shim components is a common cause of instability in the B-0 field, especially when gradient intensive sequences are used. The aim of the study was to set a benchmark for typical drift encountered during MR spectroscopy (MRS) to assess the need for real-time field-frequency locking on MRI scanners by comparing field drift data from a large number of sites.Method: A standardized protocol was developed for 80 participating sites using 99 3T MR scanners from 3 major vendors. Phantom water signals were acquired before and after an EPI sequence. The protocol consisted of: minimal preparatory imaging; a short pre-fMRI PRESS; a ten-minute fMRI acquisition; and a long post-fMRI PRESS acquisition. Both pre- and post-fMRI PRESS were non-water suppressed. Real-time frequency stabilization/adjustment was switched off when appropriate. Sixty scanners repeated the protocol for a second dataset. In addition, a three-hour post-fMRI MRS acquisition was performed at one site to observe change of gradient temperature and drift rate. Spectral analysis was performed using MATLAB. Frequency drift in pre-fMRI PRESS data were compared with the first 5:20 minutes and the full 30:00 minutes of data after fMRI. Median (interquartile range) drifts were measured and showed in violin plot. Paired t-tests were performed to compare frequency drift pre- and post-fMRI. A simulated in vivo spectrum was generated using FID-A to visualize the effect of the observed frequency drifts. The simulated spectrum was convolved with the frequency trace for the most extreme cases. Impacts of frequency drifts on NAA and GABA were also simulated as a function of linear drift. Data from the repeated protocol were compared with the corresponding first dataset using Pearson's and intraclass correlation coefficients (ICC).Results: Of the data collected from 99 scanners, 4 were excluded due to various reasons. Thus, data from 95 scanners were ultimately analyzed. For the first 5:20 min (64 transients), median (interquartile range) drift was 0.44 (1.29) Hz before fMRI and 0.83 (1.29) Hz after. This increased to 3.15 (4.02) Hz for the full 30 min (360 transients) run. Average drift rates were 0.29 Hz/min before fMRI and 0.43 Hz/min after. Paired t-tests indicated that drift increased after fMRI, as expected (p &lt; 0.05). Simulated spectra convolved with the frequency drift showed that the intensity of the NAA singlet was reduced by up to 26%, 44 % and 18% for GE, Philips and Siemens scanners after fMRI, respectively. ICCs indicated good agreement between datasets acquired on separate days. The single site long acquisition showed drift rate was reduced to 0.03 Hz/min approximately three hours after fMRI.Discussion: This study analyzed frequency drift data from 95 3T MRI scanners. Median levels of drift were relatively low (5-min average under 1 Hz), but the most extreme cases suffered from higher levels of drift. The extent of drift varied across scanners which both linear and nonlinear drifts were observed.</p

Harnessing the NEON data revolution to advance open environmental science with a diverse and data-capable community

It is a critical time to reflect on the National Ecological Observatory Network (NEON) science to date as well as envision what research can be done right now with NEON (and other) data and what training is needed to enable a diverse user community. NEON became fully operational in May 2019 and has pivoted from planning and construction to operation and maintenance. In this overview, the history of and foundational thinking around NEON are discussed. A framework of open science is described with a discussion of how NEON can be situated as part of a larger data constellation—across existing networks and different suites of ecological measurements and sensors. Next, a synthesis of early NEON science, based on >100 existing publications, funded proposal efforts, and emergent science at the very first NEON Science Summit (hosted by Earth Lab at the University of Colorado Boulder in October 2019) is provided. Key questions that the ecology community will address with NEON data in the next 10 yr are outlined, from understanding drivers of biodiversity across spatial and temporal scales to defining complex feedback mechanisms in human–environmental systems. Last, the essential elements needed to engage and support a diverse and inclusive NEON user community are highlighted: training resources and tools that are openly available, funding for broad community engagement initiatives, and a mechanism to share and advertise those opportunities. NEON users require both the skills to work with NEON data and the ecological or environmental science domain knowledge to understand and interpret them. This paper synthesizes early directions in the community’s use of NEON data, and opportunities for the next 10 yr of NEON operations in emergent science themes, open science best practices, education and training, and community building
