Socioeconomic status and anxiety as predictors of antidepressant treatment response and suicidal ideation in older adults.

BACKGROUND: Separate reports from the maintenance treatment for late-life depression (MTLD) trials have shown that low socioeconomic status (SES) and anxiety symptoms at the time of treatment initiation predict lower levels of response to antidepressant treatment and higher levels of suicidal ideation in older adults. AIM: To determine whether SES and anxiety independently contribute to worse treatment outcomes, as indicated by persistence of depressive symptoms during treatment and the persistence of suicidal ideation. Consistent with prior evidence that sociodemographic factors and clinical history are both prognostic of depression treatment efficacy, we hypothesized that SES and pre-existing anxiety symptoms will both predict lower levels of response to treatment and higher levels of suicidal ideation. METHOD: Secondary analyses of data from the MTLD trials. RESULTS: Regression analyses which controlled for comorbid anxiety indicated that residents of middle- and high-income census tracts were more likely to respond to treatment (HR, 1.63; 95%CI, 1.08-2.46) and less likely to report suicidal ideation during treatment (OR, 0.51; 95%CI, 0.28-0.90) than residents of low income census tracts. The same regression models indicated that pre-existing anxiety symptoms were independently related to lower treatment response (HR, 0.73; 95%CI, 0.60-0.89) and higher risk of suicidal ideation (OR, 1.45; 95%CI, 0.98-2.14). CONCLUSION: These findings demonstrate the importance of treating anxiety symptoms during the course of treatment for late-life depression and, at the same time, addressing barriers to treatment response related to low SES

Transforming the Publishing Academy: How Moving Online and Focusing on Diversity and Inclusion Made Scholarly Publishing Support More Accessible to Graduate Students

Academic libraries frequently offer general research support services such as literature searching and citation management workshops for graduate students, however specific scholarly communications topics such as writing for an academic publication are less frequently addressed (Gannon-Leary & Bent, 2010; Perini & Calcagno, 2013). Support for scholarly publishing, data management and other scholarly communication topics are increasingly needed, and are the type of challenges with which librarians can assist. The University of Louisville Libraries in collaboration with the Graduate School offer a biennial, interdisciplinary, five-week publishing academy for graduate students. The Publishing Academy is designed to introduce students to the scholarly publishing landscape and offer practical tips for writing and publishing in peer-reviewed journals. The first week of the academy is an introduction to the academy with the librarians leading the effort along with a tenured faculty panel discussion about academic publishing; the second week is focused on selecting a journal for one’s publication and covers topics such as copyright and open access as well as journal metrics; the third week covers writing for a publication; the fourth week is an early career (pre-tenure) and non-tenure track faculty panel discussion, and the last week is a wrap-up and a discussion about current issues in scholarly publishing. In Spring 2021, the Publishing Academy moved to an online format due to COVID, and was enhanced with diversity, equity and inclusion (DEI) content. In addition to the general overview of the publishing academy and the content and format of each session, the presenters will discuss the opportunities and challenges associated with moving an in-person program to a fully virtual format, and purposefully integrating DEI into the academy. We will share student feedback, lessons learned from the experiences, and changes we will make to the future academies. By the end of the presentation, the attendees will be able to list potential topics to cover, identify campus partnerships, reflect on how to integrate DEI into programming, and outline the potential steps for the development or enhancement of a similar program on their campus.

Application of a Six Degrees-of-Freedom Drag Model for Small Satellite Mission Development

For spacecraft in low-perigee orbits, atmospheric drag presents one of the largest uncertainties in dynamics modeling. These uncertainties are particularly relevant to small satellites, which often fly in the LEO regime and produce control forces and torques comparable in magnitude to drag. In this study, a six degrees-of-freedom orbital dynamics model with drag perturbations is developed, and several applications of the model are investigated. The model is used to evaluate differential drag dynamics for the MR and MRS SAT microsatellite pair, and the implications to collision avoidance and end-of-life procedures are discussed. Preliminary propellant usage estimates for the mission are also generated. A modified method for determining ballistic coefficient using relative satellite navigation data is introduced and compared to previous methods

An Evaluation of Guests’ Preferred Incentives to Shift Time-Variable Demand in Restaurants

Asked for their reactions to specific demand-shifting tactics based on revenue management, patrons of a restaurant in Ithaca, New York, indicated that they generally would be willing to shift their dining time to off-peak hours in exchange for discounts on menu items. Better than three-quarters of the 367 respondents agreed that they would accept an incentive for dining at an off-peak time. Specific results and conclusions are detailed below

The Turbulent Warm Ionized Medium: Emission Measure Distribution and MHD Simulations

We present an analysis of the distribution of H-alpha emission measures for the warm ionized medium (WIM) of the Galaxy using data from the Wisconsin H-Alpha Mapper (WHAM) Northern Sky Survey. Our sample is restricted to Galactic latitudes |b| > 10. We removed sightlines intersecting nineteen high-latititude classical H II regions, leaving only sightlines that sample the diffuse WIM. The distribution of EM sin |b| for the full sample is poorly characterized by a single normal distribution, but is extraordinarily well fit by a lognormal distribution, with = 0.146 +/- 0.001 and standard deviation 0.190 +/- 0.001. drops from 0.260 +/- 0.002 at Galactic latitude 10<|b|<30 to 0.038 +/- 0.002 at Galactic latitude 60<|b|<90. The distribution may widen slightly at low Galactic latitude. We compare the observed EM distribution function to the predictions of three-dimensional magnetohydrodynamic simulations of isothermal turbulence within a non-stratified interstellar medium. We find that the distribution of EM sin |b| is well described by models of mildy supersonic turbulence with a sonic Mach number of ~1.4-2.4. The distribution is weakly sensitive to the magnetic field strength. The model also successfully predicts the distribution of dispersion measures of pulsars and H-alpha line profiles. In the best fitting model, the turbulent WIM occupies a vertical path length of 400-500 pc within the 1.0-1.8 kpc scale height of the layer. The WIM gas has a lognormal distribution of densities with a most probable electron density n_{pk} = 0.03 cm^{-3}. We also discuss the implications of these results for interpreting the filling factor, the power requirement, and the magnetic field of the WIM.Comment: 16 pages, 13 figures, ApJ in press.
