Human Rights in Russia and the Former Soviet Republics: Political Repression of Islam
Central Asia, once one of the least known regions in the world, has become important to the United States since 9/11, the resulting U.S. invasion of Afghanistan, and the new “War on Terror.” Tajikistan, often considered the poorest and most obscure of the five Central Asian “Stans,” was thrust into the public view when it became useful to the United States in its 2001 invasion of Afghanistan
Inherited Toxicity: An Expanded Concept of Sustainability for Preservation
Sustainability is a concept that has been accepted as a foundation for professional practice, and toxicity of materials is gaining concern. While the topic of material toxicity is generally addressed with regard to new materials, the built environment represents a history of embedded toxins. However, this aspect of ‘inherited toxicity’ is scarcely addressed. Considering the toxic potential associated with 20th century building materials, this will grow more critical for the preservation field to address in coming years. In response to the increasing regulation of copper in both Europe and the US, the case study at Frank Lloyd Wright’s Price Tower (1956) is an exploration of whether or not an acute environmental impact from the building’s exterior copper elements exists, the results of which are assessed based on an expanded toxicology of copper
Strengthening social work education in mental health: change through inter-professional collaboration
The impacts of mental health issues are widely documented in the literature, and Social Work as a profession is challenged to respond effectively to these issues. Strengthening social work education in mental health is accordingly gaining in importance so as to enable social work students to respond effectively to these challenges through appropriate knowledge, skills, and the ability to apply these in practice. This paper presents one approach towards strengthening social work education as utilised in the 'Social Worker as a Member of a Multidisciplinary Team' project at James Cook University. It is based on the premise that inter-professional education and collaborative process, the research team identified the areas of Competence, Compassion, and Confidence as the areas that need to be strengthened in the curriculum to meet the current needs and standards of professional practice of social workers in mental health; and also identified some methods towards embedding these in the social work curriculum. The paper closes with highlighting the need for such interprofessional collaborations and the synergies that they bring to curriculum development as well as presenting some of the areas of further research that have emerged through the process
Work in Progress -- Instrumentation on a Truss Adapted for Pre-College Outreach
Engineering content is a valuable addition to pre-college instruction in science, technology, engineering, and mathematics (STEM) since it applies scientific concepts, illustrates scientific relevance and technology, and provides measurement opportunities. Also, complex systems and interactions can be shown. This work describes outreach resources using a seven-member instrumented truss apparatus. This aluminum bench-top model is scaled to support up to fifty pounds. Electrical resistance gauges are installed on several members for strain measurement. The resource set includes the truss apparatus, instrumentation, a PowerPoint presentation, and a background document. The pre-college objective is a set of demonstration resources for middle or high school classrooms. Effective outreach design is modeled by tailoring to accommodate curriculum standards, level-appropriate concept terms, and grade continuity. The resources were developed by students in an interdisciplinary college class on sensors and structures. The development activities involved testing the models and measurements and refining the construction. Selected resources were implemented and evaluated in a local middle school classroom. The interdisciplinary content includes structural, force analysis, sensing, and measurement components
Sympatric woodland Myotis bats form tight-knit social groups with exclusive roost home ranges
Background: The structuring of wild animal populations can influence population dynamics, disease spread, and information transfer. Social network analysis potentially offers insights into these processes but is rarely, if ever, used to investigate more than one species in a community. We therefore compared the social, temporal and spatial networks of sympatric Myotis bats (M. nattereri (Natterer's bats) and M. daubentonii (Daubenton's bats)), and asked: (1) are there long-lasting social associations within species? (2) do the ranges occupied by roosting social groups overlap within or between species? (3) are M. daubentonii bachelor colonies excluded from roosting in areas used by maternity groups?
Results: Using data on 490 ringed M. nattereri and 978 M. daubentonii from 379 colonies, we found that both species formed stable social groups encompassing multiple colonies. M. nattereri formed 11 mixed-sex social groups with few (4.3%) inter-group associations. Approximately half of all M. nattereri were associated with the same individuals when recaptured, with many associations being long-term (>100 days). In contrast, M. daubentonii were sexually segregated; only a quarter of pairs were associated at recapture after a few days, and inter-sex associations were not long-lasting. Social groups of M. nattereri and female M. daubentonii had small roost home ranges (mean 0.2 km2 in each case). Intra-specific overlap was low, but inter-specific overlap was high, suggesting territoriality within but not between species. M. daubentonii bachelor colonies did not appear to be excluded from roosting areas used by females.
Conclusions: Our data suggest marked species- and sex-specific patterns of disease and information transmission are likely between bats of the same genus despite sharing a common habitat. The clear partitioning of the woodland amongst social groups, and their apparent reliance on small patches of habitat for roosting, means that localised woodland management may be more important to bat conservation than previously recognised
The Role of Race in Admission to a Dual Diagnosis Unit Versus General Inpatient Psychiatric Unit in those with Active Substance Use
Psychiatric disorders are highly comorbid with substance use disorders, and the presence of co-occurring conditions increases severity of illness and complicates recovery. Those with comorbid mental illness and substance use disorders may benefit from specialized services, specifically integrated dual diagnosis treatment. Admission to a dual diagnosis unit requires health care providers to consider a number of factors, including severity of illness, psychiatric history, bed availability, and providers’ perceived likelihood of benefit of specialized services. Ideally, decisions regarding the necessity of substance use treatment are made independent of race, and yet, racial disparities exist among those who are offered substance use treatment. The aim of this study was to evaluate the demographic differences of patients who are identified as having active substance use admitted from the comprehensive psychiatric emergency program (CPEP) to a dual diagnosis unit versus those admitted to a general inpatient psychiatric unit. Our study consists of a retrospective analysis of patients, aged 18–90 (n = 100), admitted to either a dual diagnosis unit (8B) or general psychiatric unit (6K) at Mount Sinai Beth Israel (MSBI), a private metropolitan hospital in New York City, between November 1st to November 30th, 2020. We hypothesized that there are racial disparities in unit assignments while accounting for a variety of potentially relevant demographic and clinical variables. The primary outcome was a comparison of demographic factors, particularly racial composition, of those admitted to the dual diagnosis unit versus those admitted to the general psychiatric unit. After accounting for 6 clinical and 3 other demographic variables, patients of Black race were over 5 times more likely (adjusted odds ratio 5.31; P = 0.011) to be assigned to 8B than patients of White, Asian, or Other race. Additional contributors to 8B assignment were male gender, IM or IV PRNs, and documented substance use ('Table 1'). There were no significant differences between Black and Non-Black patients in rates of substance use detected on toxicology ('Table 2'). These findings suggest that race may be a driving factor in unit assignment, and unconscious racial bias may potentially confound admission decision-making, limiting access to available resources and services for some populations. More research is needed to understand factors contributing to racial disparities in substance use treatment

Genome-Wide Association Identifies Nine Common Variants Associated With Fasting Proinsulin Levels and Provides New Insights Into the Pathophysiology of Type 2 Diabetes
OBJECTIVE: Proinsulin is a precursor of mature insulin and C-peptide. Higher circulating proinsulin levels are associated with impaired β-cell function, raised glucose levels, insulin resistance, and type 2 diabetes (T2D). Studies of the insulin processing pathway could provide new insights about T2D pathophysiology. RESEARCH DESIGN AND METHODS: We have conducted a meta-analysis of genome-wide association tests of ∼2.5 million genotyped or imputed single nucleotide polymorphisms (SNPs) and fasting proinsulin levels in 10,701 nondiabetic adults of European ancestry, with follow-up of 23 loci in up to 16,378 individuals, using additive genetic models adjusted for age, sex, fasting insulin, and study-specific covariates. RESULTS: Nine SNPs at eight loci were associated with proinsulin levels (P < 5 × 10−8). Two loci (LARP6 and SGSM2) have not been previously related to metabolic traits, one (MADD) has been associated with fasting glucose, one (PCSK1) has been implicated in obesity, and four (TCF7L2, SLC30A8, VPS13C/C2CD4A/B, and ARAP1, formerly CENTD2) increase T2D risk. The proinsulin-raising allele of ARAP1 was associated with a lower fasting glucose (P = 1.7 × 10−4), improved β-cell function (P = 1.1 × 10−5), and lower risk of T2D (odds ratio 0.88; P = 7.8 × 10−6). Notably, PCSK1 encodes the protein prohormone convertase 1/3, the first enzyme in the insulin processing pathway. A genotype score composed of the nine proinsulin-raising alleles was not associated with coronary disease in two large case-control datasets. CONCLUSIONS: We have identified nine genetic variants associated with fasting proinsulin. Our findings illuminate the biology underlying glucose homeostasis and T2D development in humans and argue against a direct role of proinsulin in coronary artery disease pathogenesis
Equation of state and strength of diamond in high pressure ramp loading
Diamond is used extensively as a component in high energy density
experiments, but existing equation of state (EOS) models do not capture its
observed response to dynamic loading. In particular, in contrast with first
principles theoretical EOS models, no solid-solid phase changes have been
detected, and no general-purpose EOS models match the measured ambient
isotherm. We have performed density functional theory (DFT) calculations of the
diamond phase to ~10TPa, well beyond its predicted range of thermodynamic
stability, and used these results as the basis of a Mie-Greuneisen EOS. We also
performed DFT calculations of the elastic moduli, and calibrated an algebraic
elasticity model for use in simulations. We then estimated the flow stress of
diamond by comparison with the stress-density relation measured experimentally
in ramp-loading experiments. The resulting constitutive model allows us to
place a constraint on the Taylor-Quinney factor (the fraction of plastic work
converted to heat) from the observation that diamond does not melt on ramp
compression
Phenotypic Characterization of EIF2AK4 Mutation Carriers in a Large Cohort of Patients Diagnosed Clinically With Pulmonary Arterial Hypertension.
BACKGROUND: Pulmonary arterial hypertension (PAH) is a rare disease with an emerging genetic basis. Heterozygous mutations in the gene encoding the bone morphogenetic protein receptor type 2 (BMPR2) are the commonest genetic cause of PAH, whereas biallelic mutations in the eukaryotic translation initiation factor 2 alpha kinase 4 gene (EIF2AK4) are described in pulmonary veno-occlusive disease/pulmonary capillary hemangiomatosis. Here, we determine the frequency of these mutations and define the genotype-phenotype characteristics in a large cohort of patients diagnosed clinically with PAH. METHODS: Whole-genome sequencing was performed on DNA from patients with idiopathic and heritable PAH and with pulmonary veno-occlusive disease/pulmonary capillary hemangiomatosis recruited to the National Institute of Health Research BioResource-Rare Diseases study. Heterozygous variants in BMPR2 and biallelic EIF2AK4 variants with a minor allele frequency of <1:10 000 in control data sets and predicted to be deleterious (by combined annotation-dependent depletion, PolyPhen-2, and sorting intolerant from tolerant predictions) were identified as potentially causal. Phenotype data from the time of diagnosis were also captured. RESULTS: Eight hundred sixty-four patients with idiopathic or heritable PAH and 16 with pulmonary veno-occlusive disease/pulmonary capillary hemangiomatosis were recruited. Mutations in BMPR2 were identified in 130 patients (14.8%). Biallelic mutations in EIF2AK4 were identified in 5 patients with a clinical diagnosis of pulmonary veno-occlusive disease/pulmonary capillary hemangiomatosis. Furthermore, 9 patients with a clinical diagnosis of PAH carried biallelic EIF2AK4 mutations. These patients had a reduced transfer coefficient for carbon monoxide (Kco; 33% [interquartile range, 30%-35%] predicted) and younger age at diagnosis (29 years; interquartile range, 23-38 years) and more interlobular septal thickening and mediastinal lymphadenopathy on computed tomography of the chest compared with patients with PAH without EIF2AK4 mutations. However, radiological assessment alone could not accurately identify biallelic EIF2AK4 mutation carriers. Patients with PAH with biallelic EIF2AK4 mutations had a shorter survival. CONCLUSIONS: Biallelic EIF2AK4 mutations are found in patients classified clinically as having idiopathic and heritable PAH. These patients cannot be identified reliably by computed tomography, but a low Kco and a young age at diagnosis suggests the underlying molecular diagnosis. Genetic testing can identify these misclassified patients, allowing appropriate management and early referral for lung transplantation
