Substance Use-Related Brief Interventions With Emergency Department Patients Reduce Mental Health Co-Morbidities
Background: Research on screening and brief interventions (SBIs) has shown that, in addition to reducing alcohol use, interventions delivered in healthcare settings can reduce trauma readmissions, hospitalization days, driving offenses, and future healthcare utilization and costs. Mental health co-morbidities often accompany unhealthy alcohol and drug use, but few studies have examined the impact of SBIs on the mental health of patients. The present study determined if SBIs focused on reducing alcohol or drug use affected the mental health status of patients at a six-month follow-up.
Methods: Participants (N=1152) were randomly sampled from patients receiving SBIs for at-risk alcohol or drug use after presenting to one of two urban emergency departments (EDs) in Georgia. Telephone follow-up interviews were completed with 698 of the original participants at six months after the intervention. Mental health co-morbidities were measured at both time points using the Global Assessment of Individual Needs Short Screener (GAIN-SS) and the SF-12. Analyses were conducted using paired samples t-tests.
Results: Analyses found significant reductions in the percentage of patients reporting feelings of anxiety (45% to 33%, p\u3c0.001), depression (52% to 37%, p\u3c0.001), and suicidal ideation (13% to 8%, p\u3c0.001) as well as improvements in global mental health measures (SF12 mental health score and internalizing and externalizing subscales of the GAIN-SS).
Conclusions: Six months after receiving SBIs for alcohol and drug use in EDs, several measures of the mental health of participants showed significant improvements. Widespread implementation of SBIs in Georgia\u27s EDs may affect a broad array of public health concerns, including mental health
Radio continuum observations of local star-forming galaxies using the Caltech Continuum Backend on the Green Bank Telescope
We observed radio continuum emission in 27 local (D < 70 Mpc) star-forming
galaxies with the Robert C. Byrd Green Bank Telescope between 26 GHz and 40 GHz
using the Caltech Continuum Backend. We obtained detections for 22 of these
galaxies at all four sub-bands and four more marginal detections by taking the
average flux across the entire bandwidth. This is the first detection (full or
marginal) at these frequencies for 22 of these galaxies. We fit spectral energy
distributions (SEDs) for all of the four-sub-band detections. For 14 of the
galaxies, SEDs were best fit by a combination of thermal free-free and
nonthermal synchrotron components. Eight galaxies with four-sub-band detections
had steep spectra that were only fit by a single nonthermal component. Using
these fits, we calculated supernova rates, total number of equivalent O stars,
and star formation rates within each ~23 arcsecond beam. For unresolved
galaxies, these physical properties characterize the galaxies' recent star
formation on a global scale. We confirm that the radio-far-infrared correlation
holds for the unresolved galaxies' total 33 GHz flux regardless of their
thermal fractions, though the scatter on this correlation is larger than that
at 1.4 GHz. In addition, we found that for the unresolved galaxies, there is an
inverse relationship between the ratio of 33 GHz flux to total far-infrared
flux and the steepness of the galaxy's spectral index between 1.4 GHz and 33
GHz. This relationship could be an indicator of the timescale of the observed
episode of star formation.Comment: 36 pages, 9 figures; accepted for publication in ApJ. First and

Members of the genus Ranavirus, one of five genera withinthe family Iridoviridae, encompass a group of large, doublestrandedDNA viruses that infect all three classes of ectothermicvertebrates: fish, amphibians, and reptiles. Ranaviruses areglobally emerging pathogens that cause considerable morbidityand mortality among diverse populations. In North America,ranavirus epizootics are regularly reported in wild and culturedfish, amphibian, and reptile populations
From Social Exclusion to Supported Inclusion: Adults with Intellectual Disability Discuss Their Lived Experiences of a Sructured Social Group
Background People with intellectual disability often have few friends and experience social exclusion. Recognising this gap, supported social groups with the aim of inclusion and interdependence were created by a supported employment provider. Methods Interviews were undertaken with 10 adults with intellectual disability exploring their lived experiences of a supported social group. Data were analysed using descriptive phenomenology. Results Two themes emerged (i) supported engagement fosters wellbeing, and (ii) developing social belonging and connectedness. Participants not only acknowledged the support that they needed to participate, but also that the social group had changed their lives in many ways. Conclusions Adults with intellectual disability want to socialise, have friends and be part of their community. For this to be achieved, they recognise the need to seek some form of support. With appropriate and targeted support, adults with intellectual disability can move from social exclusion towards supported inclusion and experience richer lives

Black Family Forest Owners in the Southeastern United States: A Case Study in Six Counties
The USDA Forest Service, National Woodland Owner Survey asks family forest owners (FFOs) about their attitudes and intentions regarding their forestland. Historically, the number of responses from Black or African American FFOs has been very low, but it is uncertain whether this is because of nonresponse bias or that there are relatively few Black FFOs. To get a better understanding of these FFOs and to test a method to increase response rates, an intensified survey effort was conducted in three southern states: Alabama, North Carolina, and South Carolina. Analyses indicate that Black FFOs have slightly different objectives, activities, and ownership structure for their forestland than their White counterparts, who have traditionally represented the majority of FFOs.
Study Implications: By conducting an experiment to increase response rates from Black family forest owners to the National Woodland Owner Survey, we find traditional methodology is not effective. More importantly, we see this group has moderately different responses than their White counterparts. This has wide ranging implications for landowner assistance programs and other initiatives that have been designed on the premise that we are accurately capturing responses from all woodland owners
A Posthumanist Pragmatism: Rereading Tomboys
Gender has often dictated the roles and responsibilities that individuals are expected to fulfill. Societies in general still adhere to a strict gender binary system, and have largely been either intolerant of or, at minimum, uncomfortable with those who break from such a system. The tomboy figure has been the recipient of societal judgement for what has been interpreted to be a subversion of and deviance from traditional gender norms, and this has played out in a variety of ways. For instance, literary depictions of the tomboy—as the manifestations of the dominant cultural attitude—have captured both the aversion to as well as an evolving disposition toward non-feminine female characters. To trace and evaluate this trajectory, we utilize a framework provided by posthumanist theory, in conjunction with the pragmatic method. Important strains contained within posthumanism and pragmatism reject philosophical assumptions that there exists a single, true ontology, while promoting this-worldly notions concerning inclusion and diversity. By demonstrating how the tomboy has challenged presumptive ways of thinking, and continues to dispel preconceived notions and cultural expectations, we seek to show that the tomboy identity and disposition are to be celebrated for their authenticity and nonconformance, particularly as border-blurring and boundary-reducing, rather than deviating from or, for that matter, mirroring some purported true humanity. To accept such—that is, to hold any figure, tomboy or otherwise, as paradigmatic—would amount to a metaphysical endorsement for the knowability of a one and accurate experience, human or, even, otherwise. Alternatively, for us, the tomboy can serve as a valid model for how to undermine and help dismantle patriarchal and other prejudicial ideologies. Last, we attempt to show the increasing obsolescence of foundationalism as well as to ultimately offer the tomboy figure as a champion for continual self-enlargement, within a larger, posthumanist pragmatic process of self-creation
CHANG-ES VI: Probing Supernova Energy Deposition in Spiral Galaxies Through Multi-Wavelength Relationships
How a galaxy regulates its SNe energy into different
interstellar/circumgalactic medium components strongly affects galaxy
evolution. Based on the JVLA D-configuration C- (6 GHz) and L-band (1.6 GHz)
continuum observations, we perform statistical analysis comparing
multi-wavelength properties of the CHANG-ES galaxies. The high-quality JVLA
data and edge-on orientation enable us for the first time to include the halo
into the energy budget for a complete radio-flux-limited sample. We find tight
correlations of with the mid-IR-based SFR. The normalization of
our relation is 2-3 times of
those obtained for face-on galaxies, probably a result of enhanced IR
extinction at high inclination. We also find tight correlations between and the SNe energy injection rate , indicating
the energy loss via synchrotron radio continuum accounts for of
, comparable to the energy contained in CR electrons. The
integrated C-to-L-band spectral index is for non-AGN
galaxies, indicating a dominance by the diffuse synchrotron component. The
low-scatter /
relationships have super-linear logarithmic slopes at in L-band
(/) while consistent with linear in C-band
(/). The super-linearity could be naturally
reproduced with non-calorimeter models for galaxy disks. Using Chandra halo
X-ray measurements, we find sub-linear relations.
These results indicate that the observed radio halo of a starburst galaxy is
close to electron calorimeter, and a galaxy with higher SFR tends to distribute
an increased fraction of SNe energy into radio emission (than X-ray).Comment: 16 pages, 6 figures, 1 table, MNRAS in pres
The Role of Fraternity/Sorority Affiliation in Supporting College Student Mental Health and Wellness
Mental health is a growing concern in the United States, even more exacerbated by the recent COVID-19 pandemic. Mental health among youth and young adult populations has also received attention in recent years. However, prior research suggests a higher sense of social support among active members of the fraternity/sorority community is associated with lower depression levels. The extent to which fraternity/sorority involvement helps address mental health among members is theorized but not demonstrated in the research. Using large-scale data, this study examined mental health experiences and behaviors of the fraternity/ sorority community and compared results with unaffiliated students. Findings suggest students in the fraternity/sorority community report higher levels of positive mental health
Predicting intraurban airborne PM1.0-trace elements in a port city : Land use regression by ordinary least squares and a machine learning algorithm
Airborne particulate matter (PM) has been associated with cardiovascular and respiratory morbidity and mortality, and there is some evidence that spatially varying metals found in PM may contribute to adverse health effects. We developed spatially refined models for PM trace elements using ordinary least squares land use regression (OLS-LUR) and machine leaning random forest land-use regression (RF-LUR).
Two-week integrated measurements of PM1.0 (median aerodiameter < 1.0 μm) were collected at 50 sampling sites during fall (2010), winter (2011), and summer (2011) in the Halifax Regional Municipality, Nova Scotia, Canada. PM1.0 filters were analyzed for metals and trace elements using inductively coupled plasma-mass spectrometry. OLS- and RF-LUR models were developed for approximately 30 PM1.0 trace elements in each season. Model predictors included industrial, commercial, and institutional/ government/ military land use, roadways, shipping, other transportation sources, and wind rose information.
RF generated more accurate models than OLS for most trace elements based on 5-fold cross validation. On average, summer models had the highest cross validation R2 (OLS-LUR = 0.40, RF-LUR = 0.46), while fall had the lowest (OLS-LUR = 0.27, RF-LUR = 0.31). Many OLS-LUR models displayed overprediction in the final exposure surface. In contrast, RF-LUR models did not exhibit overpredictions. Taking overpredictions and cross validation performances into account, OLS-LUR performed better than RF-LUR in roughly 20% of the seasonal trace element models. RF-LUR models provided more interpretable predictors in most cases. Seasonal predictors varied, likely due to differences in seasonal distribution of trace elements related to source activity, and meteorology
