Article ; Online: "It's Their Consent You Have to Wait For": Intimate Partner Violence and BDSM Among Gender and Sexual Minority Youth.

Brewer, Nathan Q / Thomas, Kristie A / Guadalupe-Diaz, Xavier

Abstract	Gender and sexual minoritized (GSM) youth are more likely than their cisgender heterosexual peers to experience intimate partner violence (IPV) and practice bondage and discipline, domination and submission, sadism, and masochism (BDSM). Although IPV and BDSM are vastly different phenomena, superficial similarities (e.g., violent behaviors) can lead to misidentification in both practice and research. This study explores how GSM youth (a) experience and understand the differences between IPV and BDSM and (b) report consensual violent and controlling behaviors when answering items on IPV measures. Nine demographically diverse GSM youth (mean age 21.2) were drawn from a GSM youth-serving organization in the Northeast United States. Participants were interviewed about their experiences with IPV, BDSM, and consent. Participants also were asked to describe the process of completing two standardized measures of IPV. Interviews were coded using conventional and directed content analysis. Eight of nine participants reported IPV victimization, and seven reported BDSM interest or experiences. Four themes emerged: (a) GSM youth experience a spectrum of IPV victimization, often related to their gender and sexual identity; (b) interest in BDSM does not imply an acceptance of IPV; (c) GSM youth have a nuanced understanding of consent and strategies to communicate consent with their partners; and (d) Consent is the organizing framework by which GSM youth distinguish IPV from BDSM. Participants reported various degrees of certainty that they would include BDSM behaviors when answering questions about violent behaviors. Findings underscore the importance of conceptually and operationally differentiating IPV and BDSM. Programs that serve GSM youth should address IPV victimization, offer sex-positive education regarding healthy relationships and BDSM, and assist GSM youth in differentiating abusive behaviors from consensual BDSM. Standardized measures that do not conflate BDSM with IPV are crucial for studying IPV among GSM youth.

Abstract	Optical frequencies of the D line transitions in ^{9}Be^{+} were measured with a relative uncertainty of Δν/ν=5×10^{-11}. The results represent the highest accuracy achieved on a broad electric dipole-allowed (E1) transition in a trapped ion experiment to date, enabled in part by detailed consideration of photon recoil and quantum interference. Measurements were made on a single laser-cooled ion stored in a radio frequency Paul trap, using a spectroscopy laser stabilized to an optical frequency comb and referenced to UTC (NIST). The uncertainties in the D_{1} and D_{2} lines have been reduced by a factor of 10 and 30, respectively, compared to previous work. We have extracted the ^{2}P fine structure splitting, Δν_{fs}=197 064.54(7) MHz, and the ^{2}P_{1/2} hyperfine constant, A_{P_{1/2}}=-117.92(4) MHz.

Article ; Online: Predicting wait time for pediatric kidney transplant: a novel index.

Alvarez, Alexandra / Montgomery, Ashley / Galván, Nhu Thao Nguyen / Brewer, Eileen D / Rana, Abbas

Pediatric nephrology (Berlin, Germany)

Abstract	Background: Over one thousand pediatric kidney transplant candidates are added to the waitlist annually, yet the prospective time spent waiting is unknown for many. Our study fills this gap by identifying variables that impact waitlist time and by creating an index to predict the likelihood of a pediatric candidate receiving a transplant within 1 year of listing. This index could be used to guide patient management by giving clinicians a potential timeline for each candidate's listing based on a unique combination of risk factors. Methods: A retrospective analysis of 3757 pediatric kidney transplant candidates from the 2014 to 2020 OPTN/UNOS database was performed. The data was randomly divided into a training set, comprising two-thirds of the data, and a testing set, comprising one-third of the data. From the training set, univariable and multivariable logistic regressions were used to identify significant predictive factors affecting wait times. A predictive index was created using variables significant in the multivariable analysis. The index's ability to predict likelihood of transplantation within 1 year of listing was validated using ROC analysis on the training set. Validation of the index using ROC analysis was repeated on the testing set. Results: A total of 10 variables were found to be significant. The five most significant variables include the following: blood group, B (OR 0.65); dialysis status (OR 3.67); kidney disease etiology, SLE (OR 0.38); and OPTN region, 5 (OR 0.54) and 6 (OR 0.46). ROC analysis of the index on the training set yielded a c-statistic of 0.71. ROC analysis of the index on the testing set yielded a c-statistic of 0.68. Conclusions: This index is a modest prognostic model to assess time to pediatric kidney transplantation. It is intended as a supplementary tool to guide patient management by providing clinicians with an individualized prospective timeline for each candidate. Early identification of candidates with potential for prolonged waiting times may help encourage more living donation including paired donation chains.

Abstract	Problematic substance use and addiction is a growing crisis in the United States. As a result, identifying factors that effectively promote addiction recovery is, currently, of particular societal importance. Informed by evidence that-while addiction can be perpetuated by stress-related impulsivity and decreased self-regulation-perceived social support is protective against addiction, we test a model for addiction recovery as a form of posttraumatic growth (PTG), focused specifically on close relationships and personal strength-two domains of PTG. In an initial study, we found that perceived social support and impulsivity predicted number of relapses in individuals in a substance use disorder recovery program. Using experience sampling, we then observed that experiencing a stressful event predicted impulsive behavior. However, experiencing closeness with others-a domain of PTG-was directly associated with perceived social support, and both predicted positive emotional states, which were, in turn, inversely associated with experiencing a stressful event. Further, when experiencing a stressful event, personal strength-also a domain of PTG-was inversely associated with impulsive behavior and was predicted by both perceived social support and positive emotional states. Finally, in a follow-up experiment, we found that an ecological momentary intervention targeting perceived social support decreased impulsivity and increased self-regulation-an aspect of personal strength-in a dose-dependent fashion. Taken together, our findings: (1) support a PTG model for recovery; (2) provide evidence for processes by which close supportive relationships are protective against addiction and relapse; and (3) indicate that self-regulation is responsive to a short in-the-moment perceived social support intervention. We suggest that these findings support the theory that addiction is a social disease in the sense that close personal interactions and supportive relationships: (a) buffer against stress-related impulsivity, thereby protecting against addiction and relapse; and (b) increase personal strength, thereby decreasing the probability of impulsive-including addictive-behavior and promoting recovery.

Abstract	This research investigates the over-time stability of the aggregate US healthcare expenditure (HCE)-GDP relationship, focusing on periods of healthcare reforms. The most consequential reforms-Medicaid/Medicare and the Affordable Care Act (ACA)-are challenging to study because they occur near the ends of the available data. Using annual national- and state-level data and a battery of structural break tests, we find the HCE-GDP relationship to be overwhelmingly stable. An ancillary analysis around the 2006 Massachusetts healthcare reform, which avoids the confounding effects of the Great Recession and the staggered rollout of the ACA, likewise finds no change.

Abstract	Fusion-based additive manufacturing techniques leverage rapid solidification (RS) conditions to create parts with complex geometries, unique microscale/nanoscale morphological features, and elemental segregation. Three custom composition stainless steel alloys with varying chromium equivalence to nickel equivalence ratio (Creq/Nieq) between 1.53 and 1.95 were processed using laser powder bed fusion (LPBF) and/or two-piston splat quenching (SQ) to produce solidification rates estimated between 0.4 and 0.8 m/s. Both scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were utilized to collect high-resolution images, electron backscatter diffraction (EBSD) phase identification, and measure cellular segregation. Similar features were observed in both LPBF and SQ samples including phase and microstructure, nanoscale oxide particles, cell size, and segregation behavior. However, dislocation pileup was observed along the cell boundaries only in the LPBF austenite solidified microstructure. Targeted adjustment of the SQ feedstock Cr and Ni concentrations, within the ASTM A240 specification for 316L resulted in no observable impact on the cell size, oxide particle size, or magnitude of segregation. Also, the amount of Ni segregation in the ferrite solidified microstructures did not significantly differ, regardless of Cr/Nieq or processing technique. SQ is demonstrated as capable of simulating RS rates and microstructures similar to LPBF for use as an alternative screening tool for new RS alloy compositions.
