The Prevalence of Sexual Violence Perpetration in Sexual Minority Men: A Secondary Analysis of Systematic Review Data

Purpose: Prior literature illustrates that sexual minority people (e.g., bisexual, gay, queer) are at increased vulnerability for sexual violence victimization compared to heterosexual peers, including while in college. However, the study of sexual violence perpetration in sexual minority populations, much less specifically sexual minority college men, has been neglected. This article reviews the literature and presents a secondary data analysis of a systematic review on college men’s sexual perpetration rates and associated methodology. We also conducted analyses to summarize available literature regarding publishing dates, authors, and data inclusivity. Methods: We downloaded the dataset and associated materials from Mendeley.com’s data archive. Results: To our surprise, we could not analyze sexual perpetration prevalence rates in sexual minority men using the systematic review data due to absence of reported data across all 77 independent samples including over 5,500 male participants. We found no significant relationship between inclusion of sexual minority men and the use of measurement strategies specialized to assess sexual minority needs. We did find a positive relationship between recency of publication and the inclusion of sexual minority men, r(76) = .24, p = .03, and that most authors/co-authors were women (72%). Conclusions: Preventing perpetration is central to ending sexual violence; therefore, future research should include sexual minority people and use appropriate methodology in the investigation of sexual perpetration characteristics and patterns

VISIONS:the VISTA Star Formation Atlas I. Survey overview

VISIONS is an ESO public survey of five nearby (d < 500 pc) star-forming molecular cloud complexes that are canonically associated with the constellations of Chamaeleon, Corona Australis, Lupus, Ophiuchus, and Orion. The survey was carried out with the Visible and Infrared Survey Telescope for Astronomy (VISTA), using the VISTA Infrared Camera (VIRCAM), and collected data in the near-infrared passbands J (1.25 μm), H (1.65 μm), and KS (2.15 μm). With a total on-sky exposure time of 49.4h VISIONS covers an area of 650 deg2, it is designed to build an infrared legacy archive with a structure and content similar to the Two Micron All Sky Survey (2MASS) for the screened star-forming regions. Taking place between April 2017 and March 2022, the observations yielded approximately 1.15 million images, which comprise 19 TB of raw data. The observations undertaken within the survey are grouped into three different subsurveys. First, the wide subsurvey comprises shallow, large-scale observations and it has revisited the star-forming complexes six times over the course of its execution. Second, the deep subsurvey of dedicated high-sensitivity observations has collected data on areas with the largest amounts of dust extinction. Third, the control subsurvey includes observations of areas of low-to-negligible dust extinction. Using this strategy, the VISIONS observation program offers multi-epoch position measurements, with the ability to access deeply embedded objects, and it provides a baseline for statistical comparisons and sample completeness – all at the same time. In particular, VISIONS is designed to measure the proper motions of point sources, with a precision of 1 mas yr−1 or better, when complemented with data from the VISTA Hemisphere Survey (VHS). In this way, VISIONS can provide proper motions of complete ensembles of embedded and low-mass objects, including sources inaccessible to the optical ESA Gaia mission. VISIONS will enable the community to address a variety of research topics from a more informed perspective, including the 3D distribution and motion of embedded stars and the nearby interstellar medium, the identification and characterization of young stellar objects, the formation and evolution of embedded stellar clusters and their initial mass function, as well as the characteristics of interstellar dust and the reddening law

A myeloid program associated with COVID-19 severity is decreased by therapeutic blockade of IL-6 signaling

Altered myeloid inflammation and lymphopenia are hallmarks of severe infections. We identified the upregulated EN-RAGE gene program in airway and blood myeloid cells from patients with acute lung injury from SARS-CoV-2 or other causes across 7 cohorts. This program was associated with greater clinical severity and predicted future mechanical ventilation and death. EN-RAGE hi myeloid cells express features consistent with suppressor cell functionality, including low HLA-DR and high PD-L1. Sustained EN-RAGE program expression in airway and blood myeloid cells correlated with clinical severity and increasing expression of T cell dysfunction markers. IL-6 upregulated many EN-RAGE program genes in monocytes in vitro. IL-6 signaling blockade by tocilizumab in a placebo-controlled clinical trial led to rapid normalization of EN-RAGE and T cell gene expression. This identifies IL-6 as a key driver of myeloid dysregulation associated with worse clinical outcomes in COVID-19 patients and provides insights into shared pathophysiological mechanisms in non-COVID-19 ARDS. </p

Livestock Grazing Impacts on Crop and Soil Responses for Two Cropping Systems

Diversified crop, forage, and livestock systems are assumed to be more sustainable and economically competitive than traditional cropping systems. Objectives of this study were to determine effects of integrating grazing livestock into corn (Zea mays)-soybean (Glycine max (L.) Merr.) (C-S) and corn-soybean-wheat (Triticum aestivum L.) (C-S-W) cropping systems on plant population, grain yield, soil nutrients and soil carbon dioxide (CO2) flux following winter grazing corn residue (both systems) and an oat (Avena sativa) cover crop (C-S-W only) planted after wheat. For the 2019 and 2020 production seasons, neither corn nor soybean plant populations were different in the grazed or non-grazed treatments for the C-S and C-S-W rotations. During 2021 in the C-S rotation, soybean plant populations were greater (P \u3c 0.05) in the grazed corn residue treatment (319,556 plants ha-1) compared to the non-grazed corn residue treatment (286,520 plants ha-1). Despite observed differences in soybean plant population in this year, grazing corn residue and the oat cover crop had no impact on grain yield of soybean or corn in C-S or C-S-W or wheat grain yield in C-S-W. Similarly, for both cropping systems, soil nutrients and CO2 flux did not differ for either the grazed or non-grazed corn residue or the oat cover crop in any year of the study. To date, this partial evaluation of livestock grazing effects on grain yield suggested minimal to no reduction in plant populations in cropland grazed during winter with no apparent negative effects on either grain production or soil nutrients and CO2 flux.

Refined teaching methods, systems thinking, and experiential approaches enhanced students learning through COVID-19

The Soil Nutrient Relationships course serves juniors and seniors with a major or minor in agronomy at the University of Nebraska-Lincoln. Pre-pandemic enrollment averaged 65 students. In 2021 and 2022, course enrollment was 42 and 55, respectively. The course was adjusted to a flipped design in 2017. Moving into 2021, the Soil Nutrient Relationships course underwent a major overhaul by changing the content source materials and organization of lab activities while maintaining the flipped delivery format. While responding to the COVID-19 pandemic limitations, the redesign was intended to focus limited face-to-face meetings (in person or webconference) on problem-solving activities. This paper reports on course redesign emphasizing changes for and since the pandemic. Surveys were used in both 2021 and 2022 to assess students’ learning and reception to the course design. In surveys, students responded that they gained knowledge in all course learning objectives and increased both problem-solving and systems approach skills. The overall responses were similar between 2021 and 2022; however, one difference was that students placed a higher value on the in-person discussion and lecture in 2022 relative to Zoom discussion or video lecture in 2021. Despite working on similar problem-solving activities, 81% responded that discussion helped with problem solving skills when done via Zoom in 2021 while 88% responded that in person discussion helped with problem-solving skills in 2022. Smaller group sizes used in 2021 seemed to improve student opinions of learning; this is the one change that instructors plan to use in the future
