This thesis sought to evaluate whether the increased risk of heat-related illness observed in black-African descendants stems from impairements in local- and whole-body heat loss responses in this ethnic group. To evaluate this, in separate studies local- (study 1) and whole–body (study 2) heat loss responses were compared in young men (18-30 y) of black-African (n=21) and Caucasian (n=21) descent, matched for physical characteristics and fitness and born and raised in the same temperate environment. In study 1, we compared nitric oxide-dependent skin blood flow and sweating responses in young men of black-African (n=10) and Caucasian (n=10) descent during rest, exercise, and recovery in the heat. Both groups rested for 10-min, and then performed 50-min of moderate-intensity exercise at 200 W/m2, followed by 30-min of recovery in hot-dry heat (35°C, 20% RH). Local cutaneous vascular conductance (CVC%max) and sweat rate (SR) were measured at two forearm skin sites treated with a) lactated-Ringer (Control), or b) 10 mM NG-nitro-L-arginine methyl ester (L‐NAME, NO synthase-inhibitor). L-NAME significantly reduced CVC%max throughout rest, exercise, and recovery in both groups (both p<0.001). However, there were no significant main effects for the NO contribution to CVC%max between groups (all p>0.500). L-NAME significantly reduced local SR in both groups (both p<0.050). The NO contribution to SR was similar between groups such that L-NAME reduced SR relative to control at 40 and 50 min into exercise (both p<0.050). In study 2, we assessed whole-body total heat loss (evaporative + dry heat exchange) in black-African (n=11) and Caucasian (n=11) men using direct calorimetry. Participants performed three, 30-min bouts of semi-recumbent cycling at fixed metabolic heat productions (and therefore matched heat loss requirements between groups) of 200 (light), 250 (moderate), and 300 W/m2 (vigorous), each followed by 15-min recovery, in dry heat (40°C, ~13% relative humidity). Across all exercise bouts, dry (p=0.435) and evaporative (p=0.600) heat exchange did not differ significantly between groups. As such, total heat loss during light, moderate and vigorous exercise was similar between groups (p=0.777), averaging ((mean (SD)); 177 (10), 217 (13) and 244 (20) W/m2 in men of black-African descent, and 172 (13), 212 (17) and 244 (17) W/m2 in Caucasian men. Accordingly, body heat storage across all exercise bouts (summation of metabolic heat production and total heat loss) was also similar between the black-African (568 (142) kJ) and Caucasian groups (623 (124) kJ; p=0.356). This thesis demonstrates that ethnicity does not influence NO-dependent cutaneous vasodilation and sweating in healthy, young black-African descent and Caucasian men during exercise in the heat. Furthermore, we extend upon these observations by showing no differences in whole-body dry and evaporative heat exchange and therefore body heat storage.

Purpose: To characterize the association of social class discrimination with the timing of first cigarette use and progression to DSM-IV nicotine dependence (ND) in Black and White youth, examining variation by race, parent vs. youth experiences of discrimination, socioeconomic status (SES), and stage of smoking. Methods: Data were drawn from 1461 youth (55.2% Black, 44.8% White; 50.2% female) and mothers in a high-risk family study of alcohol use disorder and related conditions. Cox proportional hazard regression analyses were conducted, using youth’s and mother’s social class discrimination to predict first cigarette use and progression to ND, stratifying by race. Interactions between discrimination and SES indicators (parental education and household income) were tested. Adjusted models included psychiatric covariates. Results: In the adjusted first cigarette use models, neither youth’s nor mother’s social class discrimination was a significant predictor among Black youth, but mother’s discrimination was associated with increased risk [HR = 1.53 (1.18–1.99)] among White youth. In the adjusted ND models, mother’s discrimination was associated with reduced ND risk for Black youth in middle-income families [HR = 0.29 (CI 0.13–0.63)], but neither youth’s nor mother’s discrimination predicted transition to ND among White youth. Conclusions: The observed race and smoking stage-specific effects suggest that social class discrimination is more impactful on early stages of smoking for White youth and later stages for Black youth. The robustness of links with mother’s discrimination experiences further suggests the importance of considering family-level effects and the need to explore possible mechanisms, such as socialization processes.

Research examining how these athletes, specifically football players, are racially mistreated in revenue sports in Power Five conferences, as well as the effect of this mistreatment on their health and well-being, has been sparse. Thus, the purpose of my study was to examine current Black male college football players' experiences of racial mistreatment within their lives in general, and their collegiate sport experiences in particular, and to learn how these experiences have affected their health and well-being across their academic, athletic, and social spheres of functioning. Through reflexive thematic analysis, I gathered that (a) the athletes believed that football defines and limits them, (b) they felt misunderstood and isolated on campus, (b) they were dehumanized and criminalized, and (d) they were physically and psychologically exhausted from chronic racial mistreatment. Despite the NCAA making positive strides toward addressing mental health concerns within collegiate athletics, there remains a clear need for more support and nourishment regarding the mental health of Black male college athletes, particularly football players. Further results and implications are discussed.

The purpose of this study was to examine the ways in which the academic and professional experiences of Black people in American music therapy reflect current attitudes within the field towards diversity and cultural awareness, and how understanding those experiences can lead to enhanced, culturally sensitive practice. An arts-based narrative inquiry methodology using poetry was employed as a means to understand the experiences of Black people in the field through artistic forms that invite readers to enter the affective worlds of the participants. A total of 10 music therapy students, clinicians and educators participated in open-ended, semi-structured interviews. Transcripts of these interviews were analyzed for thematic material as well as to provide content for poems in the participants’ voices that described their experiences. Additionally, the researcher created poems responding to each participant that reflected on aspects of the interactions, content and sub-text of the interviews. All poems were analyzed for thematic material. That material was compared with previously derived themes out of which seven main themes emerged. Those themes are: things and people are not as they seem; being the only one/one of a few; self-definition versus being defined by others; adding value to the field; dealing with the status quo; calling for greater cultural awareness, acceptance and equality; and importance of support. Findings indicated that participants did not feel as if they fully belonged in the profession and that the music therapy community inconsistently recognized and addressed the need for diversity, cultural awareness and cultural sensitivity. Implications for music therapy training and practice, along with recommendations for the field and future research are also presented. / Music Therapy

No / As the workforce in the British National Health Service (NHS) has become more diverse, several researchers have reported that experiences of overseas nurses have been largely negative. This paper explores Black African nurses' experiences of equal opportunities, racism, and discrimination in four NHS trusts in northeastern England. Thirty nurses from sub-Saharan countries working in four NHS trusts were interviewed between 2006 and 2008 using semistructured interviews and focus group discussions to gain an insight into their experiences in the NHS. This study suggests that Black African nurses experienced discrimination and racism from White colleagues and other overseas nurses, managers, and patients and their relatives as well as lack of opportunities in their workplaces. Managers seemed to treat British and other overseas nurses more favorably than Black African nurses. Although much progress has been made in valuing and embracing diversity in the NHS, this article highlights areas in which more work is required.

During their lifetime, Black/African Americans have a higher likelihood of developing the diabetes mellitus metabolic disorder than other racial and ethnic groups in the United States. While research indicates that socioeconomic status, diet, and obesity factor into race disparities, the epigenetics field additionally identifies historical and contemporary racism as contributors to race disparities. This study is a qualitative analysis that examines a sample of health science research articles that use an epigenetics approach to understand diabetes among Black/African Americans. I analyzed the extent and mechanisms through which articles subtly reproduce dominant stereotypes of Black/African Americans and diabetes through representations of culture, diet, and sugar consumption, among other factors. Moreover, our analysis shows how these articles recreate new scripts that view biological differences as a product of historical and ongoing racism. The result of this analysis indicates three categories: 1) presentations of race as a social construction and racism as a cause of biological outcomes; 2) utilization of cultural perspectives that reify racial categories and point to social environments within households/neighborhoods and diet as a cause; 3) advocating for a multidisciplinary approach in medicine to foster collaborative change within minority communities. These results further emphasize the importance for sociologists and other research scholars to become more educated in the field of epigenetics. Furthermore, by becoming more educated on epigenetics, this can allow sociologists to further contribute to the field.
