Exploring female otolaryngologists' experiences with gender bias and microaggressions: a cross sectional Canadian survey.

BACKGROUND: Gender bias is behavior that shows favoritism towards one gender over another. Microaggressions are defined as subtle, often unconscious, discriminatory, or insulting actions that communicate demeaning or negative attitudes. Our objective was to explore how female otolaryngologists experience gender bias and microaggressions in the workplace. METHODS: Anonymous web-based cross-sectional Canadian survey was distributed to all female otolaryngologists (attendings and trainees) using the Dillman's Tailored Design Method from July to August of 2021. Quantitative survey included demographic data, validated 44-item Sexist Microaggressions Experiences and Stress Scale (MESS) and validated 10-item General Self-efficacy scale (GSES). Statistical analysis included descriptive and bivariate analysis. RESULTS: Sixty out of 200 participants (30% response rate) completed the survey (mean age 37 ± 8.3 years, 55.0% white, 41.7% trainee, 50% fellowship-trained, 50% with children, mean 9.2 ± 7.4 years of practice). Participants scored mild to moderate on the Sexist MESS-Frequency (mean ± standard deviation) 55.8 ± 24.2 (42.3% ± 18.3%), Severity 46.0 ± 23.9 (34.8% ± 18.1%), Total 104.5 ± 43.7 (39.6% ± 16.6%) and high on GSES (32.7 ± 5.7). Sexist MESS score was not associated with age, ethnicity, fellowship-training, having children, years of practice, or GSES. In the sexual objectification domain, trainees had higher frequency (p = 0.04), severity (p = 0.02) and total MESS (p = 0.02) scores than attendings. CONCLUSIONS: This was the first multicenter, Canada-wide study exploring how female otolaryngologists experience gender bias and microaggressions in the workplace. Female otolaryngologists experience mild to moderate gender bias, but have high self-efficacy to manage this issue. Trainees had more severe and frequent microaggressions than attendings in the sexual objectification domain. Future efforts should help develop strategies for all otolaryngologists to manage these experiences, and thereby improve the culture of inclusiveness and diversity in our specialty.

Real-time emotion detection by quantitative facial motion analysis.

BACKGROUND: Research into mood and emotion has often depended on slow and subjective self-report, highlighting a need for rapid, accurate, and objective assessment tools. METHODS: To address this gap, we developed a method using digital image speckle correlation (DISC), which tracks subtle changes in facial expressions invisible to the naked eye, to assess emotions in real-time. We presented ten participants with visual stimuli triggering neutral, happy, and sad emotions and quantified their associated facial responses via detailed DISC analysis. RESULTS: We identified key alterations in facial expression (facial maps) that reliably signal changes in mood state across all individuals based on these data. Furthermore, principal component analysis of these facial maps identified regions associated with happy and sad emotions. Compared with commercial deep learning solutions that use individual images to detect facial expressions and classify emotions, such as Amazon Rekognition, our DISC-based classifiers utilize frame-to-frame changes. Our data show that DISC-based classifiers deliver substantially better predictions, and they are inherently free of racial or gender bias. LIMITATIONS: Our sample size was limited, and participants were aware their faces were recorded on video. Despite this, our results remained consistent across individuals. CONCLUSIONS: We demonstrate that DISC-based facial analysis can be used to reliably identify an individual's emotion and may provide a robust and economic modality for real-time, noninvasive clinical monitoring in the future.

Narratives of Women and Gender Relations in Chinese COVID-19 Frontline Reports in 2020.

This article analyzes the representation of women in Chinese news reports about COVID-19 in order to examine the consequences of the pandemic on gender relations in China. It draws on the linguistic framework of appraisal theory for identifying evaluative language and takes Chinese news reports on the COVID-19 frontline in 2020 as the major data sources. The study finds that while the narrative about women's capacity in combating the virus, resolution in the face of adversity, and sense of responsibility help build a shared feeling of community to reconstruct the disturbed social order, the descriptions about the evaluation and feelings of female characters lead to undesirable outcomes in gender relations in China. Specifically, the newspapers' reports on COVID-19 mainly focus on group interests and accomplishments and overlook women's contributions in containing the pandemic. Meanwhile, the news reports devoted to constructing model female characters that highlight transcendent qualities place considerable pressure on everyday women. Furthermore, journalists tend to infuse their reports with gender bias when depicting women, including aesthetic appreciation of appearance and a focus on emotional reactions and domestic roles, which hinders the professional identity of women. This article sheds light on gender relations in China amid the pandemic, as well as the study of gender equality in media discourse.

Persistence of gender biases in Europe.

Prior work suggests that modern gender bias might have historical roots but has not been able to demonstrate long-term persistence of this bias due to a lack of historical data. We follow archaeological research and employ skeletal records of women's and men's health from 139 archaeological sites in Europe dating back, on average, to about 1200 AD to construct a site-level indicator of historical bias in favor of one gender over the other using dental linear enamel hypoplasias. This historical measure of gender bias significantly predicts contemporary gender attitudes, despite the monumental socioeconomic and political changes that have taken place since. We also show that this persistence is most likely due to the intergenerational transmission of gender norms, which can be disrupted by significant population replacement. Our results demonstrate the resilience of gender norms and highlight the importance of cultural legacies in sustaining and perpetuating gender (in)equality today.

Challenges of accurately estimating sex-biased admixture from X chromosomal and autosomal ancestry proportions.

Sex-biased admixture can be inferred from ancestry-specific proportions of X chromosome and autosomes. In a paper published in the American Journal of Human Genetics, Micheletti et al.1 used this approach to quantify male and female contributions following the transatlantic slave trade. Using a large dataset from 23andMe, they concluded that African and European contributions to gene pools in the Americas were much more sex biased than previously thought. We show that the reported extreme sex-specific contributions can be attributed to unassigned genetic ancestry as well as the limitations of simple models of sex-biased admixture. Unassigned ancestry proportions in the study by Micheletti et al. ranged from ∼1% to 21%, depending on the type of chromosome and geographic region. A sensitivity analysis illustrates how this unassigned ancestry can create false patterns of sex bias and that mathematical models are highly sensitive to slight sampling errors when inferring mean ancestry proportions, making confidence intervals necessary. Thus, unassigned ancestry and the sensitivity of the models effectively prohibit the interpretation of estimated sex biases for many geographic regions in Micheletti et al. Furthermore, Micheletti et al. assumed models of a single admixture event. Using simulations, we find that violations of demographic assumptions, such as subsequent gene flow and/or sex-specific assortative mating, may have confounded the analyses of Micheletti et al., but unassigned ancestry was likely the more important confounding factor. Our findings underscore the importance of using complete ancestry information, sufficiently large sample sizes, and appropriate models when inferring sex-biased patterns of demography. This Matters Arising paper is in response to Micheletti et al.,1 published in American Journal of Human Genetics. See also the response by Micheletti et al.,2 published in this issue.

Gender discrimination among women healthcare workers during the COVID-19 pandemic: Findings from a mixed methods study.

BACKGROUND: Gender discrimination among women healthcare workers (HCWs) negatively impacts job satisfaction, mental health, and career development; however, few studies have explored how experiences of gender discrimination change during times of health system strain. Thus, we conducted a survey study to characterize gender discrimination during a time of significant health system strain, i.e., the COVID-19 pandemic. METHODS: We used a convenience sampling approach by inviting department chairs of academic medical centers in the United States to forward our online survey to their staff in January 2021. The survey included one item assessing frequency of gender discrimination, and an open-ended question asking respondents to detail experiences of discrimination. The survey also included questions about social and work stressors, such as needing additional childcare support. We used ordinal logistic regression models to identify predictors of gender discrimination, and grounded theory to characterize themes that emerged from open-ended responses. RESULTS: Among our sample of 716 women (mean age = 37.63 years, SD = 10.97), 521 (72.80%) were White, 102 (14.20%) Asian, 69 (9.60%) Black, 53 (7.4%) Latina, and 11 (1.50%) identified as another race. In an adjusted model that included demographic characteristics and social and work stressors as covariates, significant predictors of higher gender discrimination included younger age (OR = 0.98, 95%CI = 0.96, 0.99); greater support needs (OR = 1.26, 95%CI = 1.09,1.47); lower team cohesion (OR = 0.94, 95%CI = 0.91, 0.97); greater racial discrimination (OR = 1.07, 95%CI = 1.05,1.09); identifying as a physician (OR = 6.59, 95%CI = 3.95, 11.01), physician-in-training (i.e., residents and fellows; OR = 3.85, 95%CI = 2.27,6.52), or non-clinical worker (e.g., administrative assistants; OR = 3.08, 95%CI = 1.60,5.90), compared with nurses; and reporting the need for a lot more childcare support (OR = 1.84, 95%CI = 1.15, 2.97), compared with reporting no childcare support need. In their open-ended responses, women HCWs described seven themes: 1) belittlement by colleagues, 2) gendered workload distributions, 3) unequal opportunities for professional advancement, 4) expectations for communication, 5) objectification, 6) expectations of motherhood, and 7) mistreatment by patients. CONCLUSIONS: Our study underscores the severity of gender discrimination among women HCWs. Hospital systems should prioritize gender equity programs that improve workplace climate during and outside of times of health system strain.

The ratio of adaptive to innate immune cells differs between genders and associates with improved prognosis and response to immunotherapy.

Immunotherapy has revolutionised cancer treatment. However, not all cancer patients benefit, and current stratification strategies based primarily on PD1 status and mutation burden are far from perfect. We hypothesised that high activation of an innate response relative to the adaptive response may prevent proper tumour neoantigen identification and decrease the specific anticancer response, both in the presence and absence of immunotherapy. To investigate this, we obtained transcriptomic data from three large publicly available cancer datasets, the Cancer Genome Atlas (TCGA), the Hartwig Medical Foundation (HMF), and a recently published cohort of metastatic bladder cancer patients treated with immunotherapy. To analyse immune infiltration into bulk tumours, we developed an RNAseq-based model based on previously published definitions to estimate the overall level of infiltrating innate and adaptive immune cells from bulk tumour RNAseq data. From these, the adaptive-to-innate immune ratio (A/I ratio) was defined. A meta-analysis of 32 cancer types from TCGA overall showed improved overall survival in patients with an A/I ratio above median (Hazard ratio (HR) females 0.73, HR males 0.86, P < 0.05). Of particular interest, we found that the association was different for males and females for eight cancer types, demonstrating a gender bias in the relative balance of the infiltration of innate and adaptive immune cells. For patients with metastatic disease, we found that responders to immunotherapy had a significantly higher A/I ratio than non-responders in HMF (P = 0.036) and a significantly higher ratio in complete responders in a separate metastatic bladder cancer dataset (P = 0.022). Overall, the adaptive-to-innate immune ratio seems to define separate states of immune activation, likely linked to fundamental immunological reactions to cancer. This ratio was associated with improved prognosis and improved response to immunotherapy, demonstrating potential relevance to patient stratification. Furthermore, by demonstrating a significant difference between males and females that associates with response, we highlight an important gender bias which likely has direct clinical relevance.

Lifesaving skills training in schools - A qualitative study to explore students, teachers, and parent's perceived opportunities and challenges.

OBJECTIVE: The objective of this study is to explore the perception of teachers, parents and students' regarding implementation of a school-based lifesaving skills program and help predict potential barriers and solutions. METHODS: This qualitative exploratory study was conducted in Karachi, Pakistan, from December 2020- to October 2021. We included students, teachers, and parents of secondary (grades VIII, IX, and X) and higher secondary level students (grades XI and XII) in Karachi, Pakistan's public and private schools and colleges. We selected one public, two semi-private, and two private schools. We recruited students, teachers, and parents through convenience sampling. We conducted fifteen focus group discussions (FGDs) with the students, six FGDs with the teachers, and eighteen in-depth interviews (IDIs) with parents. We transcribed the data from audio recordings and translated it into the English language. Finally, we manually analyzed the data using thematic analyses. RESULTS: This study found that bystanders' main barriers to performing lifesaving skills are lack of knowledge, fear of legal involvement, fear of hurting the patient by incorrect technique, lack of empathy among community stakeholders, and gender bias. However, the participants had a positive and supportive attitude toward implementing lifesaving skills training in schools. They suggested starting student training in the early teenage years, preferred medical staff as trainers, and suggested frequent small sessions in English/Urdu both or Urdu language and training via theory and practical hands-on drills. Furthermore, the training was proposed to be integrated into the school curriculum to make it sustainable. Finally, the government needs to support the program and make the legal environment more conducive for bystanders. CONCLUSION: This study identified the significant barriers to performing lifesaving skills in an emergency in a low- and middle-income country (LMIC). The participants supported implementing a national lifesaving skills program in schools and colleges. However, the participants expressed that support is needed by the government for sustainability, integrating lifesaving skills into the school curriculum, providing legal support to the bystanders, and creating awareness among the general public.

Group Dynamics and Allocation of Advanced Heart Failure Therapies-Heart Transplants and Ventricular Assist Devices-By Gender, Racial, and Ethnic Group.

Background US regulatory framework for advanced heart failure therapies (AHFT), ventricular assist devices, and heart transplants, delegate eligibility decisions to multidisciplinary groups at the center level. The subjective nature of decision-making is at risk for racial, ethnic, and gender bias. We sought to determine how group dynamics impact allocation decision-making by patient gender, racial, and ethnic group. Methods and Results We performed a mixed-methods study among 4 AHFT centers. For ≈ 1 month, AHFT meetings were audio recorded. Meeting transcripts were evaluated for group function scores using de Groot Critically Reflective Diagnoses protocol (metrics: challenging groupthink, critical opinion sharing, openness to mistakes, asking/giving feedback, and experimentation; scoring: 1 to 4 [high to low quality]). The relationship between summed group function scores and AHFT allocation was assessed via hierarchical logistic regression with patients nested within meetings nested within centers, and interaction effects of group function score with gender and race, adjusting for patient age and comorbidities. Among 87 patients (24% women, 66% White race) evaluated for AHFT, 57% of women, 38% of men, 44% of White race, and 40% of patients of color were allocated to AHFT. The interaction between group function score and allocation by patient gender was statistically significant (P=0.035); as group function scores improved, the probability of AHFT allocation increased for women and decreased for men, a pattern that was similar irrespective of racial and ethnic groups. Conclusions Women evaluated for AHFT were more likely to receive AHFT when group decision-making processes were of higher quality. Further investigation is needed to promote routine high-quality group decision-making and reduce known disparities in AHFT allocation.

Gender Inequalities in Publications about COVID-19 in Spain: Authorship and Sex-Disaggregated Data.

Gender inequalities in biomedical literature have been widely reported in authorship as well as the scarcity of results that are stratified by sex in the studies. We conducted a bibliometric review of articles on COVID-19 published in the main Spanish medical journals between April 2020 and May 2021. The purpose of this study was to analyse differences in authorship order and composition by sex and their evolution over time, as well as the frequency of sex-disaggregated empirical results and its relationship with the author sex in articles on COVID-19 in the main Spanish biomedical journals. We identified 914 articles and 4921 authors, 57.5% men and 42.5% women. Women accounted for 36.7% of first authors and for 33.7% of last authors. Monthly variation in authorship over the course of the pandemic indicates that women were always less likely to publish as first authors. Only 1.0% of the articles broke down empirical results by sex. Disaggregation of results by sex was significantly more frequent when women were first authors and when women were the majority in the authorship. It is important to make gender inequalities visible in scientific dissemination and to promote gender-sensitive research, which can help to reduce gender bias in clinical studies as well as to design public policies for post-pandemic recovery that are more gender-equitable.

Suppression of Clothing-Induced Acoustic Attenuation in Robotic Auscultation.

For patients who are often embarrassed and uncomfortable when exposing their breasts and having them touched by physicians of different genders during auscultation, we are developing a robotic system that performs auscultation over clothing. As the technical issue, the sound obtained through the clothing is often attenuated. This study aims to investigate clothing-induced acoustic attenuation and develop a suppression method for it. Because the attenuation is due to the loss of energy as sound propagates through a medium with viscosity, we hypothesized that the attenuation is improved by compressing clothing and shortening the sound propagation distance. Then, the amplitude spectrum of the heart sound was obtained over clothes of different thicknesses and materials in a phantom study and human trial at varying contact forces with a developed passive-actuated end-effector. Our results demonstrate the feasibility of the attenuation suppression method by applying an optimum contact force, which varied according to the clothing condition. In the phantom experiments, the attenuation rate was improved maximumly by 48% when applying the optimal contact force (1 N). In human trials, the attenuation rate was under the acceptable attenuation (40%) when applying the optimal contact force in all combinations in each subject. The proposed method promises the potential of robotic auscultation toward eliminating gender bias.

Daily Heterosexist Experiences in LGBTQ+ Adults from Spain: Measurement, Prevalence, and Clinical Implications / Las experiencias diarias heterosexistas en adultos LGBTQ+ de España: medición, prevalencia e implicaciones clínicas

Lesbian, gay, bisexual, transgender, and queer (LGBTQ+) individuals face unique stressors related to their sexual and gender identities that have a detrimental impact on their mental health. Nonetheless, studies have not yet investigated these minority stressors among LGBTQ+ individuals from Spain. The limited availability of standardized tools/instruments to measure minority stressors in Spanish makes it challenging to explore these experiences among Spanish speaking individuals. The present study aimed to examine the factor structure of the Daily Heterosexist Experiences Questionnaire (DHEQ) among LGBTQ+ adults from Spain, compare rates of minority stressors across diverse gender and sexual orientations, and examine the impact of daily heterosexist experiences (henceforth referred to as heterosexist experiences) on symptoms of depression and suicidal behavior. The sample was composed of 509 LGBTQ+ identifying adults in the age range of 18 to 60 years old. Confirmatory factor analysis indicated a good fit for the six dimensions of the DHEQ scale. Individuals identified as transgender or reporting a minority sexual orientation (i.e., asexual, pansexual) indicated higher levels of exposure to heterosexist experiences. Moreover, those with higher levels of heterosexist experiences had higher symptoms of depression and suicide behavior. The present study provides a tool for examining minority stressors in Spanish speaking LGBTQ+ adults. Assessing for minority stressors may aid in the identification of risk and protective factors when working with LGBTQ+ treatment seeking adults. (AU)

Las personas lesbianas, gais, bisexuales, transexuales y queer (LGBTQ+) enfrentan en su día a día estresores únicos relacionados con sus identidades sexuales y de género que pueden perjudicar a su salud mental. Sin embargo, no hay investigación que explore estos estresores minoritarios en población LGBTQ+ de España. La limitada disponibilidad de instrumentos estandarizados para medir los estresores minoritarios/experiencias heterosexistas en español dificulta hoy en día explorar estas experiencias en las personas de habla hispana. El presente estudio tiene como objetivo examinar la estructura factorial del Cuestionario de Experiencias Heterosexistas Diarias (DHEQ, según sus siglas en inglés) en adultos LGBTQ+ de España, comparar las tasas de experiencias heterosexistas en diversas identidades de género y orientaciones sexuales y examinar el impacto de las experiencias heterosexistas en los síntomas de depresión y comportamiento suicida. La muestra constaba de 509 adultos LGBTQ+ en el rango de edad de 18 a 60 años. El análisis factorial confirmatorio indica un buen ajuste para las seis dimensiones de la escala DHEQ. Las personas que se identificaron como trans o con una orientación sexual minoritaria (por ejemplo, asexual, pansexual) indicaban mayores niveles de exposición a experiencias heterosexistas. Además, niveles más altos de experiencias heterosexistas se asocian a mayores síntomas de depresión y comportamiento suicida. El presente estudio proporciona una herramienta para examinar experiencias heterosexistas en población adulta LGBTQ+ de habla hispana. La evaluación de experiencias heterosexistas puede ayudar en la identificación de factores de riesgo y de protección cuando se trabaja con adultos LGBTQ+ en el ámbito clínico. (AU)

The impacts of profound gender discrimination on the survival of girls and women in son-preference countries - A systematic review.

Amartya Sen first used the phrase 'missing women' to describe a survival disadvantage for women exposed to extreme gender discrimination in son-preference countries. In 1989 he estimated that, despite a biological survival advantage for females, there were 100 million fewer women in Asia and north Africa than expected. He blamed corrosive gender discrimination restricting the resources needed for survival. This systematic review examined demographic evidence on the impacts of profound gender discrimination on the survival of girls and women in son-preference countries. Thirty-four included studies provided consistent evidence of lower-than-expected female survival in 15 societies. Male-to-female sex ratios rose particularly in China and India between the 1980s and 2010s, despite general improvements in female mortality. High sex ratios in South Korea, however, returned to biologically normal levels. The number of 'missing women' rose steadily from 61 million in 1970 to 126 million in 2010 and was predicted to continue to rise until 2035. The number of 'missing women' in the world increased in relative and absolute terms between 1980 and 2020. Profound discrimination reduces female survival at every stage of life. Future research is needed to understand the complete pathways and mechanisms leading to poorer survival and the major policy drivers of these trends to devise the best possible ways of preventing the tragedy of 'missing women'.

Representation of women in orthopaedic surgery: perception of barriers among undergraduate medical students in Saudi Arabia.

BACKGROUND: While female participation has improved in several surgical specialties over time globally, no such increase has been observed in orthopaedic surgery over the past decades. The potential barriers to female participation are likely present from the beginning of medical education. Therefore, this study assessed the apparent lag in equal representation among men and women in orthopaedic surgery in the Kingdom of Saudi Arabia. METHODS: This cross-sectional study used a questionnaire survey to investigate medical students' and interns' perceptions of women participating in orthopaedic surgery, their subspeciality preferences, and barriers preventing them from pursuing an orthopaedic career. The responses were analysed to understand general perceptions, gender-based differences, impact of clinical experiential learning, and exposure to orthopaedic surgery. RESULTS: Approximately 565 medical students (49% females, 51% males) participated in the survey. Only 17% of students (11% females, 23% males) considered orthopaedic surgery as their future career option. While 31% of female and 17% of male students disagreed with the concept of female-appropriate orthopaedic subspecialties, most of the remaining male and female students perceived paediatric orthopaedics as a female-appropriate subspecialty. Concerning equal representation of women, gender bias and lack of a strong physique were the most frequently selected barriers by female and male students, respectively. Patient preference for male orthopaedicians, gender discrimination, social and family commitments, and need for physical strength were all perceived as barriers for women in orthopaedics. Overall, clinical experience and orthopaedic exposure did not significantly improve the likelihood of female students in choosing orthopaedic surgery as a career. CONCLUSIONS: The bias against women in orthopaedic careers is prevalent among medical students early in their academic years. Clinical experience and exposure to orthopaedic surgery should be improved to make a significant impact on female participation in orthopaedic careers. Career building efforts in terms of improved career opportunities, career counselling, flexible working hours, social and family related adjustments and implementation of mentorship/research/fellowship programmes for females are needed to reduce gender discrimination and improve female orthopaedic participation. Furthermore, process improvements may yield greater flexibility for women pursuing the challenging field while accommodating other barriers faced by women in orthopaedic surgery.

International Women in Biomechanics: Promoting, supporting, and sustaining the careers of women in biomechanics.

Gender biases and inequities are prevalent across many scientific fields and biomechanics is likely no exception. While progress has been made to support women in the field, especially at biomechanics society conferences, the recent COVID-19 pandemic has exacerbated professional isolation. The International Women in Biomechanics (IWB) community started in July 2020 with the mission of fostering an environment for women and other under-represented genders in biomechanics to gain year-round support, visibility, and allyship. Nearly 700 biomechanists have joined the IWB community from over 300 universities/organizations and 33 countries. Our community ranges in career stages and professions and interacts through a forum-style platform, teleconference meetings, and social media. In 2021, we conducted a survey to identify the needs, concerns, and issues faced by individuals in the IWB community. We received 144 responses from members in 16 countries. Our survey revealed three primary needs for women in biomechanics: supportive working environments, career planning support, and addressing workplace gender bias. These results, in conjunction with scientific evidence on workforce gender bias, helped us identify three key areas to meet our mission: Member Support, Community Outreach, and Empowering Allyship. Several levels of support are required in these three areas to ensure a lasting, positive, and sustainable impact on gender equity in biomechanics. We conclude by providing our perspectives on an evidence-based call to action to continue addressing gender bias and inequity at the individual, institutional, and scientific society levels. These actions can collectively enhance our allyship for women in the field of biomechanics.

Gender bias in teaching evaluations: the causal role of department gender composition.

Women are underrepresented in academia's higher ranks. Promotion oftentimes requires positive student-provided course evaluations. At a U.S. university, both an archival and an experimental investigation uncovered gender discrimination that affected both men and women. A department's gender composition and the course levels being taught interacted to predict biases in evaluations. However, women were disproportionately impacted because women were more often in the gender minority. A subsequent audit of the university's promotion guidelines suggested a disproportionate impact on women's career trajectories. Our framework was guided by role congruity theory, which poses that workplace positions are gendered by the ratios of men and women who fill them. We hypothesized that students would expect educators in a department's gender majority to fill more so essential positions of teaching upper-level courses and those in the minority to fill more so supportive positions of teaching lower-level courses. Consistent with role congruity theory when an educator's gender violated expected gendered roles, we generally found discrimination in the form of lower evaluation scores. A follow-up experiment demonstrated that it was possible to change students' expectations about which gender would teach their courses. When we assigned students randomly to picture themselves as students in a male-dominated, female-dominated, or gender-parity department, we shifted their expectations of whether men or women would teach upper- and lower-level courses. Violating students' expectations created negative biases in teaching evaluations. This provided a causal link between department gender composition and discrimination. The importance of gender representation and ameliorating strategies are discussed.
