A superdimension formula for gl(m|n) modules

We give a formula for the superdimension of a finite-dimensional simple gl(m|n)-module using the Su-Zhang character formula. As a corollary, we obtain a simple algebraic proof of a conjecture of Kac-Wakimoto for gl(m|n), namely, a simple module has nonzero superdimension if and only if it has maximal degree of atypicality. This conjecture was proven originally by Serganova using the Duflo-Serganova associated variety.Comment: 7 pages, no figure

City Leadership to Promote Black Male Achievement

This municipal action guide highlights potential strategies and promising city approaches for reducing the persistent disparities between black males and their peers in the areas of education, work, and family

Four in Ten Adults with Disabilities Experienced Unfair Treatment in Health Care Settings, at Work, or When Applying for Public Benefits in 2022

In this brief, we used December 2022 data from a nationally representative survey of adults ages 18 to 64 to examine rates at which adults with and without disabilities reported they were treated or judged unfairly in the past year in three settings: at doctors' offices, clinics, or hospitals; at work; and when applying for public benefits. We also examined the impact of such treatment on their well-being.Despite important federal antidiscrimination protections, people with disabilities experience unfair treatment in health care settings, workplaces, and when applying for public benefits. Understanding and addressing these experiences is necessary to ensure that people with disabilities have equitable access to health care, employment opportunities, and economic support essential for meeting basic needs

The Role of Formal Policy To Promote Informed Consent of Psychotropic Medications For Youth in Child Welfare Custody: a National Examination

Active participation of youth and surrogate decision-makers in providing informed consent and assent for mental health treatment is critical. However, the procedural elements of an informed consent process, particularly for youth in child welfare custody, are not well defined. Given calls for psychotropic medication oversight for youth in child welfare custody, this study proposes a taxonomy for the procedural elements of informed consent policies based upon formal and informal child welfare policies and then examines whether enacted state formal policies across the United States endorsed these elements. A sequential multi-method study design included: (1) semi-structured interviews with key informants (n = 58) primarily from state child welfare agencies to identify a taxonomy of procedural elements for informed consent of psychotropic medications and then (2) a legislative review of the 50 states and D.C. to characterize whether formal policies endorsed each procedural element through February 2022. Key informants reported five procedural elements in policy, including how to: (1) gather social and medical history, (2) prescribe the medication, (3) authorize its use through consent and youth assent, (4) notify relevant stakeholders, and (5) routinely review the consenting decision. Twenty-three states endorsed relevant legislation; however, only two states specified all five procedural elements. Additionally, the content of a procedural element, when included, varied substantively across policies. Further research and expert consensus are needed to set best practices and guide policymakers in setting policies to advance transparency and accountability for informed consent of mental health treatment among youth in child welfare custody

Closing the Coverage Gaps: Reducing Health Insurance Disparities in Massachusetts

Massachusetts has been exemplary in developing health insurance coverage policies to cover its residents. By 2019, the state's uninsurance rate was 3.0 percent, the lowest rate in the nation, representing about 204,000 uninsured residents. While the state's overall uninsured rate at a given point in time is low, more than twice as many people - 503,000, or 7.3 percent of the population - experienced a gap in coverage over the previous twelve months. And importantly, not all groups benefit equally. People who are Black or Hispanic, or who have lower incomes, experience significantly higher rates of uninsurance than the state population overall. As a result, these groups are more likely to face access barriers and financial insecurity associated with being uninsured.The purpose of this report is to begin charting a course toward closing the coverage gaps in Massachusetts, with a particular focus on creating a more racially and ethnically equitable system of coverage. The report and accompanying infographics describe the people in Massachusetts without health insurance and the barriers to coverage they face, including affordability, administrative complexity, and immigration, language, and cultural barriers. It then proposes a menu of policy options that address the specific circumstances in Massachusetts. The proposed options are meant to inform a statewide conversation about the best approaches to closing the remaining coverage gaps in Massachusetts and removing structural barriers that result in racial and ethnic disparities in health insurance coverage

Genome-wide association meta-analyses to identify common genetic variants associated with hallux valgus in Caucasian and African Americans

Objective Hallux valgus (HV) affects ∼36% of Caucasian adults. Although considered highly heritable, the underlying genetic determinants are unclear. We conducted the first genome-wide association study (GWAS) aimed to identify genetic variants associated with HV. Methods HV was assessed in three Caucasian cohorts (n=2263, n=915 and n=1231 participants, respectively). In each cohort, a GWAS was conducted using 2.5 M imputed SNPs. Mixed-effect regression with the additive genetic model adjusted for age, sex, weight and within-family correlations was used for both sex-specific and combined analyses. To combine GWAS results across cohorts, fixed-effect inverse-variance meta-analyses were used. Following meta-analyses, top-associated findings were also examined in an African American cohort (n=327). Results The proportion of HV variance explained by genome-wide genotyped SNPs was 50% in men and 48% in women. A higher proportion of genetic determinants of HV were sex specific. The most significantly associated SNP in men was rs9675316 located on chr17q23-a24 near the AXIN2 gene (p=0.000000546×10−7); the most significantly associated SNP in women was rs7996797 located on chr13q14.1-q14.2 near the ESD gene (p=0.000000721×10−7). Genome-wide significant SNP-by-sex interaction was found for SNP rs1563374 located on chr11p15.1 near the MRGPRX3 gene (interaction p value =0.0000000041×10−9). The association signals diminished when combining men and women. Conclusions The findings suggest that the potential pathophysiological mechanisms of HV are complex and strongly underlined by sex-specific interactions. The identified genetic variants imply contribution of biological pathways observed in osteoarthritis as well as new pathways, influencing skeletal development and inflammation

Psychopathy and Suicidal Thoughts and Behaviors Revisited: Results From a Statewide Population of Institutionalized Youth

Suicide is the leading cause of death for incarcerated youth, and up to half of all juveniles in confinement experience suicidal ideation in addition to other psychopathology, including psychopathic personality features. Unfortunately, limited research has investigated the psychopathy–suicidality link among juvenile delinquents and using newer psychopathy measures. Based upon a statewide population of incarcerated juvenile offenders, we found that psychopathy was a significant risk factor for suicidal ideation and lifetime suicide attempts, but the latter relationship was attenuated by lifetime depression diagnosis. In addition, certain affective psychopathic features such as Stress Immunity conferred protection against suicidality, whereas behavioral and lifestyle components including Carefree Nonplanfulness, Blame Externalization, and Rebellious Nonconformity were positively linked to suicidal thoughts among the youth offenders. As these risk factors are routinely screened for in juvenile justice settings, this study’s findings have considerable implications to applied practice and prevention among juvenile justice involved youth
