How State-Level Affirmative Action Bans Affect Underrepresented Students’ Opportunities and Outcomes

This study replicates a study by Peter Hinrichs; which found affirmative action bans negatively affect within institution graduation rates for minorities and the fraction of minorities who graduate from selective institutions. Since then, five more states have implemented affirmative action bans. (Figure 1) Although the effects of affirmative action bans are not clear, research suggests underrepresented minority students (black, Hispanic, and Native American) experience: Lower graduation rates overall Lower graduation rates from quantitative-intense degrees A higher likelihood of being first generation college student Research supports the economic value of higher education for students, colleges, and society, and its ability to improve human capital acquisition and labor market discrimination

Influential Article Review - Understanding Maritime Team Workload and Patterns of Coordination in Routine and Contingency Situations

This paper examines management and innovation. We present insights from a highly influential paper. Here are the highlights from this paper: The introduction of next-generation technologies to the maritime shipping industry, including Portable Pilotage Units, Remote Pilotage, advanced situation awareness aids, and Autonomous Shipping, creates an urgent need to understand operator workload during Bridge Team operations, and co-operations with shore based personnel. In this paper we analyse the mental workload of maritime Captains, Pilots and Tug Masters during standard and emergency scenarios, using traditional measures (SWAT, ISA), communications analysis, and the collection of simultaneous electro-dermal activity (EDA) of team members. Results indicate that the EDA measure overcomes some of the problems with paper-based techniques, and has excellent temporal resolution for emergency events. Implications for testing of novel technologies are discussed. For our overseas readers, we then present the insights from this paper in Spanish, French, Portuguese, and German

Implicit Bias in Speech-Language Pathology: A Journey Towards Inclusive Care

Despite long-lasting attempts to erase biases between people, this is still an issue that exists, even if subconsciously. The purpose of this research project is to investigate the presence and impact of implicit bias on assessment and treatment of speech disorders among multilingual individuals. This will be done with a specific methodology, called a Matched-Guise Test (MGT). MGT is a survey technique created to unveil covert attitudes toward linguistic varieties, including accents, dialects, and languages. In order to measure this bias, we will hire voice actors who are native English speakers and non-native speakers, to record voice samples that resemble disordered speech and non-disordered speech. These recordings will be paired to pictures of individuals who identify as white and non-white. We will match the same voice samples to more than one picture so that we can manipulate the racial presentation of the speaker. Not only can this allow us to assess current SLP’s ability to distinguish dialect from disorder, it will also give us insight on the impact of racial bias on diagnosis accuracy, as well. It is expected to see bias in areas of disordered speech with a dialect, based on prior research This survey will be distributed among practicing speech-language pathologists across the United States. We seek to quantify the extent to which these biases impact the quality of assessment, diagnosis, and treatment for multilingual individuals. Our research findings aim to shed light on the presence and impact of racial biases and linguistic biases within the field of speech pathology, ultimately contributing to efforts to promote equitable and unbiased care for multilingual individuals. The results can also allow us to better inform diversity, equity, and inclusion training, in order to train more culturally competent clinicians and educators

National priorities for dementia care : perspectives of individuals living with dementia and their care partners

The current article reports the consensus recommendations from individuals living with dementia and their care partners on priorities for public policy and research funding, which were found using a nationwide, Delphi study. A modified snowball sample was used. Listservs, personal contacts, and advocacy groups were asked to distribute the survey. Paper versions were provided upon request. In Rounds 1 and 2 of the study, 388 and 301 responses, respectively, were received. Borda counts produced a ranked order consensus of priorities. Research ranked third, after the need for caregiver support and resources for the provision of long-term care. Education and training in person-centered practices for all care partners was also a high priority. Responses indicated that research funding should be expanded beyond its current emphasis on cure. Policymakers should reconsider the current priorities of the National Alzheimer's Project Act to better address the long-term needs of individuals living with dementia and their care partners

Testing for sexually transmitted infections in general practice: cross-sectional study

Background: Primary care is an important provider of sexual health care in England. We sought to explore the extent of testing for chlamydia and HIV in general practice and its relation to associated measures of sexual health in two contrasting geographical settings.Methods: We analysed chlamydia and HIV testing data from 64 general practices and one genitourinary medicine (GUM) clinic in Brent (from mid-2003 to mid-2006) and 143 general practices and two GUM clinics in Avon (2004). We examined associations between practice testing status, practice characteristics and hypothesised markers of population need (area level teenage conception rates and Index of Multiple Deprivation, IMD scores).Results: No HIV or chlamydia testing was done in 19% (12/64) of general practices in Brent, compared to 2.1% (3/143) in Avon. In Brent, the mean age of general practitioners (GPs) in Brent practices that tested for chlamydia or HIV was lower than in those that had not conducted testing. Practices where no HIV testing was done had slightly higher local teenage conception rates (median 23.5 vs. 17.4/1000 women aged 15-44, p = 0.07) and served more deprived areas (median IMD score 27.1 vs. 21.8, p = 0.05). Mean yearly chlamydia and HIV testing rates, in practices that did test were 33.2 and 0.6 (per 1000 patients aged 15-44 years) in Brent, and 34.1 and 10.3 in Avon, respectively. In Brent practices only 20% of chlamydia tests were conducted in patients aged under 25 years, compared with 39% in Avon.Conclusions: There are substantial geographical differences in the intensity of chlamydia and HIV testing in general practice. Interventions to facilitate sexually transmitted infection and HIV testing in general practice are needed to improve access to effective sexual health care. The use of routinely-collected laboratory, practice-level and demographic data for monitoring sexual health service provision and informing service planning should be more widely evaluated

Short-term breast cancer survival in relation to ethnicity, stage, grade and receptor status: national cohort study in England.

BACKGROUND: In the re-organisation of cancer registration in England in 2012, a high priority was given to the recording of cancer stage and other prognostic clinical data items. METHODS: We extracted 86 852 breast cancer records for women resident in England and diagnosed during 2012-2013. Information on age, ethnicity, socio-economic status, comorbidity, tumour stage, grade, morphology and oestrogen, progesterone and HER2 receptor status was included. The two-year cumulative risk of death from any cause was estimated with the Kaplan-Meier method, and univariate and multivariate Cox proportional hazards regressions were used to estimate hazard ratios (HR) and their 95% confidence intervals (95% CI). The follow-up ended on 31 December 2014. RESULTS: The completeness of registration for prognostic variables was generally high (around 80% or higher), but it was low for progesterone receptor status (41%). Women with negative receptor status for each of the oestrogen, progesterone and HER2 receptors (triple-negative cancers) had an adjusted HR for death of 2.00 (95%CI 1.84-2.17). Black women had an age-adjusted HR of 1.77 (1.48-2.13) compared with White women. CONCLUSIONS: The excess mortality of Black women with breast cancer has contributions from socio-economic factors, stage distribution and tumour biology. The study illustrates the richness of detail in the national cancer registration data. This allows for analysis of cancer outcomes at a high level of resolution, and may form the basis for risk stratification

Home-based exercise rehabilitation in addition to specialist heart failure nurse care: design, rationale and recruitment to the Birmingham Rehabilitation Uptake Maximisation study for patients with congestive heart failure (BRUM-CHF): a randomised controlled trial

BACKGROUND: Exercise has been shown to be beneficial for selected patients with heart failure, but questions remain over its effectiveness, cost-effectiveness and uptake in a real world setting. This paper describes the design, rationale and recruitment for a randomised controlled trial that will explore the effectiveness and uptake of a predominantly home-based exercise rehabilitation programme, as well as its cost-effectiveness and patient acceptability. METHODS/DESIGN: Randomised controlled trial comparing specialist heart failure nurse care plus a nurse-led predominantly home-based exercise intervention against specialist heart failure nurse care alone in a multiethnic city population, served by two NHS Trusts and one primary care setting, in the United Kingdom. 169 English speaking patients with stable heart failure, defined as systolic impairment (ejection fraction ≤ 40%). with one or more hospital admissions with clinical heart failure or New York Heart Association (NYHA) II/III within previous 24-months were recruited. Main outcome measures at 1 year: Minnesota Living with Heart Failure Questionnaire, incremental shuttle walk test, death or admission with heart failure or myocardial infarction, health care utilisation and costs. Interviews with purposive samples of patients to gain qualitative information about acceptability and adherence to exercise, views about their treatment, self-management of their heart failure and reasons why some patients declined to participate. The records of 1639 patients managed by specialist heart failure services were screened, of which 997 (61%) were ineligible, due to ejection fraction>40%, current NYHA IV, no admission or NYHA II or more within the previous 2 years, or serious co-morbidities preventing physical activity. 642 patients were contacted: 289 (45%) declined to participate, 183 (39%) had an exclusion criterion and 169 (26%) agreed to randomisation. DISCUSSION: Due to safety considerations for home-exercise less than half of patients treated by specialist heart failure services were eligible for the study. Many patients had co-morbidities preventing exercise and others had concerns about undertaking an exercise programme

Analysis of protein-coding genetic variation in 60,706 humans

Large-scale reference data sets of human genetic variation are critical for the medical and functional interpretation of DNA sequence changes. We describe the aggregation and analysis of high-quality exome (protein-coding region) sequence data for 60,706 individuals of diverse ethnicities generated as part of the Exome Aggregation Consortium (ExAC). This catalogue of human genetic diversity contains an average of one variant every eight bases of the exome, and provides direct evidence for the presence of widespread mutational recurrence. We have used this catalogue to calculate objective metrics of pathogenicity for sequence variants, and to identify genes subject to strong selection against various classes of mutation; identifying 3,230 genes with near-complete depletion of truncating variants with 72% having no currently established human disease phenotype. Finally, we demonstrate that these data can be used for the efficient filtering of candidate disease-causing variants, and for the discovery of human “knockout” variants in protein-coding genes

Hair Cortisol in Twins : Heritability and Genetic Overlap with Psychological Variables and Stress-System Genes

A. Palotie on työryhmän jäsen.Hair cortisol concentration (HCC) is a promising measure of long-term hypothalamus-pituitary-adrenal (HPA) axis activity. Previous research has suggested an association between HCC and psychological variables, and initial studies of inter-individual variance in HCC have implicated genetic factors. However, whether HCC and psychological variables share genetic risk factors remains unclear. The aims of the present twin study were to: (i) assess the heritability of HCC; (ii) estimate the phenotypic and genetic correlation between HPA axis activity and the psychological variables perceived stress, depressive symptoms, and neuroticism; using formal genetic twin models and molecular genetic methods, i.e. polygenic risk scores (PRS). HCC was measured in 671 adolescents and young adults. These included 115 monozygotic and 183 dizygotic twin-pairs. For 432 subjects PRS scores for plasma cortisol, major depression, and neuroticism were calculated using data from large genome wide association studies. The twin model revealed a heritability for HCC of 72%. No significant phenotypic or genetic correlation was found between HCC and the three psychological variables of interest. PRS did not explain variance in HCC. The present data suggest that HCC is highly heritable. However, the data do not support a strong biological link between HCC and any of the investigated psychological variables.Peer reviewe
