AbstractThe examination of student group performance is a constant need as American higher education continues to expand and become more racially and ethnically diverse. Recent scholarship on the academic performance of Black students at elite colleges and universities has glossed over possible disparities among these students, particularly among different immigrant groups. The current study clarifies these differences in academic performance by examining four Black student groups at elite colleges and universities in the United States: native Blacks, Black immigrants from Africa, Black immigrants from the Caribbean and Latin America, and Black immigrants from other parts of the globe. The analyses point to many similarities and differences among the four Black student groups in their characteristics and influences on their academic performance in college such as gender, precollege friendships, high school academic preparation, college major, and closeness to Whites and Blacks. Additionally, this study found evidence of possible colorism among Black students at elite colleges.

AbstractCathy Cohen’s (1999) theory of secondary marginalization helps to explain why the needs of some members of Black communities are not prioritized on “the” Black political agenda; indeed, some groups are ignored altogether as mainstream Black public opinion shifts to the right (Tate 2010). However, the contemporary movement for Black Lives calls for an intersectional approach to Black politics. Its platform requires participants to take seriously the notion that since Black communities are diverse, so are the needs of its members. To what extent are Blacks likely to believe that those who face secondary marginalization should be prioritized on the Black political agenda? What is the role of linked fate in galvanizing support around these marginalized Blacks? To what extent does respectability politics serve to hinder a broader embrace of Blacks who face different sets of interlocking systems of oppression, such as Black women, formerly incarcerated Blacks, undocumented Black people, and Black members of LBGTQ communities in an era marked by Black social movements? We analyze data from the 2016 Collaborative Multi-Racial Post-Election Survey (CMPS) to assess whether all Black lives matter to Black Americans.

Abstract We assessed whether race moderates the association between flourishing and all-cause mortality. We used panel data from the Midlife in the United States Study (MIDUS) (1995–2016; n = 2,851). Approximately 19% of White respondents and 23% of Black respondents in the baseline sample died over the course of the 21-year study period (n = 564). Cox proportional hazard models showed that Blacks had a higher mortality rate relative to Whites and higher levels of flourishing were associated with a lower mortality rate. Furthermore, a significant interaction between flourishing and race in predicting death was observed. Blacks with higher levels of flourishing had a mortality rate that was not significantly different from that of Whites. However, Blacks, but not Whites, with low flourishing scores had a higher mortality rate. As such, health-promotion efforts focused on enhancing flourishing among Black populations may reduce the Black–White gap in mortalityrate.

AbstractWe explore the gender gap in college completion among Blacks and Whites. Using the National Education Longitudinal Study of 1988, we examine how early school achievement and educational expectations affect attainment by following a nationally representative sample of youths from 1988 (approximately age fourteen) to 2000 (approximately age twenty-six). The odds of attaining an associate's or a bachelor's degree among Black women are greater than the odds among White men after controlling for family socioeconomic status. However, the difference between Black men and White men is additionally dependent on differences in middle school and high school achievement and in high school sequencing.

In this article we examine a range of media discourses surrounding the continued existence of the Mäori All Blacks, a “racially” selected rugby side, and a specific public controversy that erupted in New Zealand over the selection of former All Black great Christian Cullen for the Mäori All Blacks in 2003. Having never played for the Mäori All Blacks or publicly identified as Mäori, Cullen claimed tangata whenua status via whakapapa (genealogical connection) to his Ngäi Tahu grandfather. We argue that Cullen’s selection emerged as a contentious issue because of the fragmentation that the inclusion of his “Whiteness” within the confines of “an Other” team (i.e., the Mäori All Blacks) brought to bear on traditional colonial binaries of race in the context of late capitalism. Finally, we locate the debates over Cullen’s selection and the continued existence of the Mäori All Blacks in relation to the current racialized political climate that has fueled a Right-wing reaction to the growing Mäori self-determination movement.

Black residential segregation has been declining in the United States. That accomplishment rings hollow, however, if blacks continue to live in much poorer neighborhoods than other Americans. This study uses census data for all US metropolitan areas in 1980 and 2010 to compare decline in the neighborhood poverty gap between blacks and other Americans with decline in the residential segregation of blacks. We find that both declines resulted primarily from narrowing differences between blacks and whites as opposed to narrowing differences between blacks and Hispanics or blacks and Asians. Because black–white differences in neighborhood poverty declined much faster than black–white segregation, the neighborhood poverty disadvantage of blacks declined faster than black segregation—a noteworthy finding because the narrowing of the racial gap in neighborhood poverty for blacks has gone largely unnoticed. Further analysis reveals that the narrowing of the gap was produced by change in both the medians and shapes of the distribution of poverty across the neighborhoods where blacks, whites, Hispanics, and Asians reside.

Latinos are a large, highly segregated minority group achieving less than whites in school, but the extent to which segregation is responsible for their relatively low achievement is not well known. The effect of proportion Latino on educational achievement is often assumed to be identical to the effect of proportion black. I use the NELS to test this assumption. Results reveal that segregation concentrates disadvantages for Latinos and blacks, but surprisingly, proportion Latino tends to positively influence test scores over the high school years. Proportion black, in contrast, does not affect test scores except for a negative effect for blacks in science. Integration of Latinos with whites would reduce some of the inequalities between schools, it would not hurt and in some areas would help the test scores of whites, but it would hurt Latinos unless some of the helpful features of predominantly Latino schools could be copied.

Is the protracted foreclosure crisis eroding the Black middle class? Foreclosure rates in the United States have reached an all-time high. Blacks have been hit especially hard by this crisis. I focus here on intraclass distinctions within the Black middle class precisely because scholars and journalists so often fail to distinguish between the experiences of the Black lower middle class and those of middle and upper-class Blacks, leaving the unintended impression that middle-class Blacks all have the same odds of losing their home. I argue that conventional explanations of the foreclosure crisis as a racialized event should be amended to account for the differential impact of the crisis on three distinct groups of middle-class Blacks: the lower middle class, the core middle class, and the upper or elite middle class.

This study updates information on the representation, roles, and occupational portrayal of African-Americans in television advertisements. A content analysis often prime time television shows revealed that black representation in television ads exceeded the percentage distribution of blacks in the population in 1991. The percentage of ads showing blacks in major roles has remained relatively stable over time. However, a black model's level of product interaction was found to be a function of the value of the product, with lower valued products having higher black model-product interaction than higher valued products. This study also compared black portrayal and representation on “typical” versus “black-oriented” television shows. The results indicate that “black-oriented” shows had a greater percentage of all black ads, ads with blacks in major roles, and ads depicting blacks in skilled occupational categories compared to “typical” shows.

Abstract Background: Using Pennsylvania Medicare claims from 1995 to 1996, the authors previously reported that anesthesia procedure length appears longer in blacks than whites. In a new study using a different and larger data set, the authors now examine whether body mass index (BMI), not available in Medicare claims, explains this difference. The authors also examine the relative contributions of surgical and anesthesia times. Methods: The Obesity and Surgical Outcomes Study of 47 hospitals throughout Illinois, New York, and Texas abstracted chart information including BMI on elder Medicare patients (779 blacks and 14,596 whites) undergoing hip and knee replacement and repair, colectomy, and thoracotomy between 2002 and 2006. The authors matched all black Medicare patients to comparable whites and compared procedure lengths. Results: Mean BMI in the black and white populations was 30.24 and 28.96 kg/m2, respectively (P < 0.0001). After matching on age, sex, procedure, comorbidities, hospital, and BMI, mean white BMI in the comparison group was 30.1 kg/m2 (P = 0.94). The typical matched pair difference (black–white) in anesthesia (induction to recovery room) procedure time was 7.0 min (P = 0.0019), of which 6 min reflected the surgical (cut-to-close) time difference (P = 0.0032). Within matched pairs, where the difference in procedure times was greater than 30 min between patients, blacks more commonly had longer procedure times (Odds = 1.39; P = 0.0008). Conclusions: Controlling for patient characteristics, BMI, and hospital, elder black Medicare patients experienced slightly but significantly longer procedure length than their closely matched white controls. Procedure length difference was almost completely due to surgery, not anesthesia.

Abstract The genetic polymorphisms in human glutathione S-transferases (GST) M1 and T1 have been associated with race, disease risk, and outcome of some adult cancers. Also, there are racial differences in the incidence and characteristics of childhood acute lymphoblastic leukemia (ALL). Our objectives were to compare the frequency of the null genotype for GSTM1, GSTT1, or both in children with ALL to that in healthy controls, and to determine whether GST genotype was associated with treatment outcome and prognostic factors. We studied GSTM1 and GSTT1 genotypes in somatic cell DNA from black children and white children with ALL and in 416 healthy controls, using a polymerase chain reaction technique. Ninety of 163 (55.2%) white ALL patients and 14 of 34 (41.2%) black patients were GSTM1 null, frequencies not significantly different (P = .19) than healthy controls (53.5% in whites and 27.6% in blacks), although there was a trend toward more null genotypes in black ALL patients. Twenty-three of 163 (14.1%) white ALL patients and 12 of 34 (35.3%) black ALL patients were GSTT1 null, not different (P = .34) than the frequencies in healthy controls (15.0% in whites and 24.1% in blacks). However, the frequency of the “double-null” genotype, lacking both GSTM1 and GSTT1, was higher in black patients with ALL (8 of 34 or 23.5%) than in black controls (3.9%) (P = .0005), but this was not the case in white patients with ALL (10 of 163 or 6.1%) compared to white controls (8.0%) (P = .68). In stratified analyses, the GST double-null genotype was not associated with other characteristics that might differ between whites and blacks with ALL, such as age, T-lineage immunophenotype, presenting white blood cell count, DNA index, or insurance status. The null genotype for GSTM1, GSTT1, or both was not found to be a prognostic factor for disease-free survival or probability of hematologic remission; central nervous system relapse tended to be less common in those with the GSTM1 null genotype (P = .054) . The double-null genotype for GSTM1 and GSTT1 is more common among blacks but not whites with childhood ALL. These data suggest that GST genotype, coupled with unidentified additional risk factors, may play a role in risk of childhood ALL in American blacks.

Abstract We compared initial screening data of 44,149 whites (17,043 men; 27,106 women) and 26,947 blacks (9,788 men; 17,159 women) who reported no previous diagnosis of hemochromatosis or iron overload from a primary care-based sample of ~100,000 adults ≥25 years recruited from 5 Field Centers. Each underwent transferrin saturation (TfSat) and serum ferritin (SF) measurements without regard to fasting, and HFE C282Y and H63D genotyping. We observed these mean TfSat and SF values and percentages of participants with elevated biochemical measurements (TfSat >50% and SF >300 ng/mL, men; TfSat >45% and SF >200 ng/mL, women): Participants Mean % TfSat (95% CI) Elevated TfSat, % Participants Mean SF, ng/mL (95% CI) Elevated SF, % Participants White men 32.4 (32.3, 32.6) 7.05 150.9 (149.1, 152.8) 19.49 Black men 29.3 (29.1, 29.5) 4.03 178.4 (175.5, 181.3) 25.95 p Value <0.0001 <0.0001 <0.0001 <0.0001 White women 27.5 (27.3, 27.6) 6.62 63.0 (62.3, 63.7) 8.74 Black women 23.3 (23.1, 23.4) 3.04 68.3 (67.2, 69.4) 15.43 p Value <0.0001 <0.0001 <0.0001 <0.0001 In participants grouped by decade, mean TfSat was greater in white men than in black men, and in white women than in black women (all p<0.0001). Mean SF was greater in black men than in white men in all decades except 25–34 years, and in black women than in white women in decades ≥45 years. SF increased with age to ~45 years in white men and ~50 years in black men, and then decreased. In white women, SF rose with age until ~62 years and less rapidly to age ≥80. In black women, SF rose with age until ~62 years and then decreased. C282Y allele frequency was 0.0700 (95% CI: 0.0683, 0.0717) in whites and 0.0119 (0.0110, 0.0129) in blacks. H63D allele frequency was 0.1532 (0.1509, 0.1556) in whites and 0.0299 (0.0284, 0.0313) in blacks. Frequencies of genotypes with C282Y or H63D were greater in whites than in blacks (all p<0.0001). The prevalence of elevated TfSat and SF plus genotype C282Y/C282Y was 0.003 in whites and 0.00004 in blacks (p<0.0001). The prevalence of elevated TfSat and SF plus genotype C282Y/C282Y, C282Y/H63D, or H63D/H63D was 0.006 in whites and 0.0003 in blacks (p<0.0001). We conclude that: 1) the prevalence of elevated TfSat is higher in whites and the prevalence of elevated SF is higher in blacks; 2) SF levels increase with age; 3) HFE C282Y and H63D alleles occur more frequently in whites than in blacks; and 4) the prevalence of elevated TfSat and SF plus genotypes with two common HFE mutations is greater in whites than in blacks.

Autosomal dominant polycystic kidney disease (ADPKD) is a frequent cause of ESRD, but its frequency in blacks has not been well delineated and its course and the effects of sickle hemoglobin in this disease in blacks have not been previously reported. The occurrence of ADPKD in blacks and whites was determined in two ESRD populations: all ESRD patients seen over a 16-yr period in one area of Southeast Tennessee and all ESRD patients in 15 hemodialysis units in Tennessee and Atlanta, GA. The frequency of sickle hemoglobin was determined and compared in a group of nonrelated blacks with ESRD with and without ADPKD. The age at onset of ESRD and factors that might affect ADPKD such as gender, hypertension, and hemoglobin type were examined. ADPKD was a less frequent cause of ESRD in blacks than whites (1.4 versus 6.8%). However, after adjusting for the population rate, the incidence rates in blacks and whites were similar (0.48 and 0.47 of 100,000). There was a higher incidence of sickle hemoglobin in nonrelated blacks with ADPKD versus other black ESRD patients (50 versus 7.5%; P < 0.005). Blacks had an earlier onset of ESRD than whites (43.2 versus 55.4 yr; P < 0.0001), as did blacks with sickle-cell trait versus blacks without (38.2 versus 48.1 yr; P < 0.003). In this population, hypertension and gender had no effect on the onset of ESRD. ADPKD accounted for a smaller percentage of blacks than whites with ESRD because of the high percentage of blacks with renal disease from other causes.(ABSTRACT TRUNCATED AT 250 WORDS)

Government agencies rely on surveys in which individuals self-report their smoking activities, which raises questions about biases in responses. To validate self-reported smoking numbers, medical researchers often rely on urinary concentrations of cotinine, the main metabolite of nicotine. But virtually all existing studies investigate whether self-reported nonsmokers misreport their smoking status. Such investigations leave unanswered whether individuals who admit smoking nonetheless smoke more than they claim. This article produces two findings of interest, both pertaining to self-reported smoking among Blacks. First, among self-reported nonsmokers, a Black person is approximately 47% more likely to smoke compared with a non-Black person. Second, among individuals who admit to smoking, the average Black smoker underreports his smoking activity by a larger amount than 70% of all self-reported smokers. Slower metabolism of cotinine among Blacks explains some, but not all, of those numbers.

Carbon blacks were used as catalysts for hydrogen production through hydrocarbon decomposition. The aim of this work is to find suitable conditions for decomposition reaction to cut down the net cost of hydrogen production. Carbon blacks after hydrocarbon decomposition under different operation conditions were mixed with NBR rubber. The surface area of carbon black increased with low weight gain in methane decomposition caused by carbon deposits on the surface of carbon black aggregates, and the decrease of surface area with further weight gain might be due to the carbon deposits adhering to each other and forming bigger aggregates. The same results were gotten from decomposition of mixture gas of methane and propane. The surface area of carbon black always decreased with the development of propane decomposition reaction. With the same carbon black loading, the composites filled by carbon blacks with low weight gain in methane and methane-propane mixture gas decompositions showed higher tensile strength than those mixed with raw carbon blacks, but there were no significant differences in 300% modulus. With the increase of carbon blacks loading in all composites, 300% modulus and tensile strength always increased. The surface resistivity of composites showed that it was much easier for carbon blacks with low weight gain in methane and methane-propane mixture gas decompositions to dissipate well in the in rubber system.

The black journalist and politician, Roscoe Simmons, was best known for his ability as an orator. Simmons's lecturing activities reveal the networks underlying a black public sphere upon which ambitious black leaders relied to publicize their political agendas. Those networks expanded in the first half of the twentieth century as blacks exploited the press, radio, and other technologies, and as blacks migrated in numbers from the Southern states. Meetings of African Americans served several functions: as opportunities to debate the race's prospects; to voice political concerns; and as sources of entertainment. Simmons incorporated all these principles in his platform performances, as he worked to secure valuable connections with organizations ranging from churches and fraternal bodies to Republican clubs and urban machines. Beginning with his family connection to Booker T. Washington, Simmons cultivated friendships with influential blacks and whites over a period of fifty years. His conservative ideology, however, did not suit all tastes.

The Utah Department of Health currently groups African-born blacks with U.S.-born blacks when reporting HIV/AIDS surveillance data. Studies suggest that categorizing HIV/AIDS cases in this manner may mask important epidemiological trends, and the distinct differences between these two populations warrant disaggregating data prior to reporting. The purpose of this study was to characterize the HIV/AIDS positive populations in U.S. and African-born blacks in Utah and evaluate the need for disaggregating the two groups. A total of 1,111 cases were identified through the statewide electronic HIV/AIDS Reporting System from 2000 - 2009. Data were analyzed for prevalence of HIV diagnosis for African-born blacks, U.S.-born blacks, and U.S.-born whites. Secondary analysis included HIV diagnosis by age, sex, African region of nativity, transmission risk factors, and differences in late diagnosis of HIV infection. U.S.-born whites accounted for 914 (82.3%) cases, and had the lowest annual prevalence (4/100,000). Conversely, African-born and U.S.- born blacks had the highest prevalence, 162/100,000 and 24/100,000 respectively. African-born blacks made up 0.25% of the total population, but accounted for 7.9% of all HIV/AIDS cases. African-born black males were more likely to report “no reported risk” for HIV transmission than U.S.-born black males. Of African-born blacks, 55.7% reported East-African nativity. These results demonstrate the importance of stratifying the black/African American racial category by African-born and U.S.-born blacks when collecting and reporting HIV/AIDS state surveillance data even in a low-incidence state,which will better inform prevention and linkage-to-care efforts in Utah.

Abstract Introduction Text-messaging programs for smoking cessation improve abstinence outcomes in the general population. However, little is known about engagement and abstinence outcomes among African Americans in text-messaging smoking cessation programs. The current study compares engagement and abstinence between Blacks and Whites in the National Cancer Institute’s SmokefreeTXT program. Method Data were from Blacks (n = 1333) and Whites (n = 7154) who enrolled in the 6-week SmokefreeTXT program between August 2017 and June 2018. We assessed the association between race and program initiation and completion; responses to weekly smoking cessation, mood, and craving assessments; and self-reported abstinence using multivariable logistic regression. Results Blacks and Whites initiated the program at a similar frequency, yet Blacks were more likely to complete the program (adjusted odds ratio [AOR] = 1.71, 95% confidence interval [CI] = 1.43 to 2.06). Blacks were less likely to respond to all seven abstinence, mood, and craving assessments (eg, AOR of quit day responses = 0.63, 95% CI = 0.51 to 0.77; 6-week AOR = 0.50, 95% CI = 0.34 to 0.72). Self-reported abstinence was lower among Blacks for all seven smoking assessments (eg, quit day abstinence AOR = 0.52, 95% CI = 0.41 to 0.68; 6-week abstinence AOR = 0.58, 95% CI = 0.38 to 0.89). Conclusion Although Blacks were more likely than Whites to complete the SmokefreeTXT program, they were less likely to engage with the program by responding to assessment questions and had lower abstinence rates. Qualitative research may reveal unique barriers to engagement among Blacks. Implications Black smokers enrolled in a nationwide mobile smoking cessation program at a rate comparable to White smokers. However, they were significantly less likely to engage with the program or quit smoking. This study highlights the need to examine barriers to cessation for Black smokers.

Objectives: Despite our knowledge on the effect of cognitive test score on subsequent risk of mortality, few studies have compared Blacks and Whites for this association. The current study was conducted on Black-White differences in the magnitude of the association between baseline cognitive test score and all-cause mortality in a nationally representative sample of adults in the United States over 25 years.
Methods: We used data of the Americans’ Changing Lives Study (ACL), 1986 – 2011, a national prospective cohort in U.S. The study followed 3,361 adults (2,205 White and 1,156 Blacks), age 25 and older, for up to 25 years. The independent variable was cognitive test score measured at baseline (1986) using the 4-item version of the Short Portable Mental Status Questionnaire, treated in two different ways (as a dichotomous and as a continuous variable). The dependent variable was time to death (due to all causes) during the follow up period. Covariates included baseline age, gender, education, income, number of chronic diseases, self-rated health, and depressive symptoms. Race (Black versus White) was the focal effect modifier. We used a series of Cox proportional hazards models in the total sample, and by race, in the absence and presence of health variables.
Results: Overall, cognitive test score predicted mortality risk. A significant interaction was found between race and baseline cognitive test score suggesting that baseline cognitive test score has a weaker protective effect against all-cause mortality for Blacks in comparison to Whites. In race-stratified models, cognitive test score at baseline predicted risk of all-cause mortality for Whites but not Blacks, in the absence and presence of baseline socio-economic and health variables. The results were similar regardless of how we treated baseline cognitive test score.
Conclusions: In the United States, baseline cognitive test score has a weaker protective effect against all-cause mortality over a long period of time for Blacks than Whites. The finding is in line with the Minorities Diminished Returns theory and is probably due to structural and interpersonal racism.

Abstract Based on the concepts of the occlusion of rubber and random packing of spheres whose volume is equivalent to that permeated by individual aggregates, an equation was deduced to estimate the distance between carbon-black aggregates in filled rubber. It was found that when the interaggregate distance reaches a critical point which is approximately identical for all carbon blacks investigated (furnace blacks), the elastic modulus measured at very low strain deviates from the modified Guth-Gold equation. Tan δ and resilience are mainly determined by the distance between aggregates. These phenomena are related to filler networking which is determined by the attractive potential and the distance between individual aggregates. Since the factor Sf, used to characterize the strength of secondary filler networks in hydrocarbon rubbers and measured by means of inverse gas chromatography, is approximately the same for all furnace blacks, the interaggregate distance seems to determine filler networking. A comparison of fillers with different Sf (graphitized vs. nongraphitized carbon blacks, carbon black vs. silica) shows that at the same interaggregate distance, a lower Sf leads to higher tan δ of the filled vulcanizates.

Objective Survival differences in oral cancer between black and white patients have been reported, but the contributing factors, especially the role of stage, are incompletely understood. Furthermore, the outcomes for Hispanic and Asian patients have been scarcely examined. Study Design Retrospective, population-based national study. Setting Surveillance, Epidemiology, and End Results 18 Custom database (January 1, 2010, to December 31, 2014). Subjects and Methods In total, 7630 patients with primary squamous cell carcinoma in the oral cavity were classified as non-Hispanic white (white), non-Hispanic black (black), Hispanic, or Asian. Cox regression was used to obtain unadjusted and adjusted hazard ratios (HRs) of 5-year mortality for race/ethnicity with sequential adjustments for stage and other covariates. Logistic regression was used to examine the relationship between race/ethnicity and stage with adjusted odds ratios (aORs). Results The cohort consisted of 75.0% whites, 7.6% blacks, 9.1% Hispanics, and 8.3% Asians. Compared to whites, the unadjusted HR for all-cause mortality for blacks was 1.68 ( P < .001), which attenuated to 1.15 ( P = .039) after adjusting for stage and became insignificant after including insurance. The unadjusted HRs for all-cause mortality were not significant for Hispanics and Asians vs whites. Compared to whites, blacks and Hispanics were more likely to present at later stages (aORs of 2.63 and 1.42, P < .001, respectively). Conclusion The greater mortality for blacks vs whites was largely attributable to the higher prevalence of later stages at presentation and being uninsured among blacks. There was no statistically significant difference in mortality for Hispanics vs whites or Asians vs whites.

The goal of this study was to analyze trends in black age-adjusted mortality rates (AADR) from 1900 through 2010 and to propose explanations. Analyses included a descriptive study of trends in AADR from major causes for blacks and age-specific all-cause mortality at each decade. In 1900, all-cause AADRs were higher for blacks than whites. Over the century, differences decreased substantially. Reductions mortality were greatest among young people, lowest among older adults. Deaths from infectious diseases showed the greatest decrease. Heart disease mortality among blacks increased from 1920 to 1950, then decreased by 2010. For men and women, AADRs for cancer rose to a peak in 1990, then declined. Stroke mortality decreased steadily for males and females. AADRs from unintentional injuries (not including motor vehicle injury) decreased gradually. Despite widespread societal resistance, blacks have made substantial gains in a wide range of social determinants of health, such as civil rights, education, employment, income, and housing. Substantial gains remain to be made.

The “housing quotient”—the condition of and access to housing—is defined for black American families and is examined in conjunction with the major relevant federal policies and programs. Policies considered include fair housing and the national urban policy. Programs examined include public housing and rental assistance. The lack of data constrains the completeness of the analysis, although certain programs seem to enroll blacks in disproportion to the rest of the population. The paper concludes that blacks currently are served by all federal programs, even though many programs historically have failed to live up to their potential to assist blacks.

This research investigated the stereotypes associated with rap music and hip-hop culture, and how those stereotypes may influence anti-Black attitudes and justifications for discrimination. In three studies—using a representative sample from America, as well as samples from two different countries—we found that negative stereotypes about rap are pervasive and have powerful consequences. In all three samples, negative attitudes toward rap were associated with various measures of negative stereotypes of Blacks that blamed Blacks for their economic plights (via stereotypes of laziness). Anti-rap attitudes were also associated with discrimination against Blacks, through both personal and political behaviors. In both American samples, the link between anti-rap attitudes and discrimination was partially or fully mediated by stereotypes that convey Blacks' responsibility. This legitimizing pattern was not found in the UK sample, suggesting that anti-rap attitudes are used to reinforce beliefs that Blacks do not deserve social benefits in American society, but may not be used as legitimizing beliefs in other cultures.

By the time Congress passed the 1964 Civil Rights Act, 98% of non-southern blacks (40% of all blacks) already resided in states with “fair employment” laws prohibiting labor market discrimination. Using census data from the Integrated Public Use Microdata Series, the author assesses the impact of fair employment legislation on black workers' relative income, unemployment, labor force participation, migration, and occupational and industrial distributions. In general, the fair employment laws adopted in the 1940s appear to have had larger effects than those adopted in the 1950s, and the laws had considerably smaller effects on the labor market outcomes of black men than on those of black women.

Addressing Mbembe’s interview with Goldberg and reflecting upon the book – Critique of Black Reason (2017) – that the interview probes, the author points to a tension in Mbembe’s thought. Mbembe apprehends black reason as all-at-once ‘reason’s unreason’ and the remaking-reasonable of reason. In this respect, there is a clear sense of a simultaneity of imposition–struggle and destruction–repair. Yet this ethos of simultaneity is in tension with Mbembe’s sequential exposition of the black archive, especially the indebtedness of the ‘response’ by blacks to the reasoning about blacks. In his response, the author works through the productive tension between ethos and sequence as a way to demonstrate the richness of Mbembe’s curation of a black archive.

Objective We assessed the racial (Black–White) differences in glycemic control, prevalence of abnormal lipid profiles and factors influencing temporal trends in children with type 1 diabetes (T1DM). Methods This retrospective study was done in children with T1DM. The outcome measure was based on glycemic control and all lipid determinations which were stratified according to the published guidelines. Results The study included 181 children; 76.2% Whites and 23.8% Blacks. The mean glycated hemoglobin (A1C) was higher in Blacks than in Whites (p < 0.0001). Blacks had elevated total cholesterol (TC) (p = 0.0013), lower TC/HDL ratio (p < 0.0001) and higher concentration of HDL (<0.0001) when compared to Whites. The longitudinal analyses over a 5 year period showed changes in A1C significantly associated with changes in the lipid profiles. The lipid profiles in Blacks were more altered by the trend in A1C with changes in the TC (p = 0.0079), non-HDL (p < 0.0001) and HDL (p < 0.0001). Conclusions Black children with T1DM have poorer glycemic control. However they retained excellent levels of HDL when compared to Whites.

The author uses restricted geocoded tract-level panel data (1986–2014) that span the prison boom and the acceleration of residential segregation in the United States from two cohorts of the National Longitudinal Survey of Youth (1979 and Children and Young Adults) to study whether the association between childhood neighborhood disadvantage and adult incarceration varies by race and ethnicity. Sibling fixed-effects models suggest that exposure to childhood neighborhood disadvantage increases the likelihood of incarceration in adulthood, net of observed and unobserved adjustments. However, the association appears weakest for blacks, especially black boys, compared with whites and Latinos. This suggests a more consistent likelihood of incarceration for blacks across all neighborhood origins. The author discusses potential theoretical explanations, including discrimination in profiling, policing, surveillance, and other prejudicial policies in the criminal justice system that are likely to uniquely affect blacks from all neighborhoods.

Abstract Abstract 478 Black-White Differences in Venous Thrombosis Risk: The Longitudinal Investigation of Thromboembolism Etiology (LITE). Neil A. Zakai, Pamela L. Lutsey, Aaron R. Folsom, Mary Cushman. Introduction: Venous thrombosis (VT) is more common in blacks than whites. The reasons for this difference and whether it is explained by racial differences in VT risk factors is not known. Methods: VT was ascertained by physician review of medical records in the Longitudinal Investigation of Thromboembolism Etiology (LITE), a prospective observational study of 21,680 men and women age 45–100 years participating in the Atherosclerosis Risk in Communities Study (ARIC) and the Cardiovascular Health Study (CHS) cohorts. VT was classified as provoked if preceded within 90 days by major surgery, trauma, immobility, or associated with active cancer or chemotherapy. We used age- and sex-adjusted Cox models to evaluate whether certain VT risk factors explained the increased risk of VT in blacks vs whites. We also tested if the impact of VT risk factors differed by race using interaction terms. Most risk factors were assessed in both ARIC and CHS cohorts (body mass index (BMI), diabetes, hypertension, chronic kidney disease (CKD), factor VIII, and education) except the activated partial thromboplastin time (aPTT), von Willebrand factor (vWF), and protein C were measured in ARIC only and C-reactive protein was measured in CHS only. Results: With up to 15 years of follow up, among 20,964 participants (5,054 blacks) without VT at baseline, 648 developed new VT (200 blacks). The age- and sex-standardized incidence of VT per 1000 person-years was higher in blacks than whites for all VT (3.18 vs 1.96), whether the VT was provoked (2.11 vs. 1.24) or unprovoked (1.12 vs. 0.74), all p <0.01. Blacks and whites had a similar incidence of pulmonary embolism (PE) (0.83 vs. 0.76, p = 0.56). Blacks had more adverse levels of many VT risk factors except CKD and a lower aPTT: BMI (29.3 vs. 26.8 kg/m2), diabetes (21 vs 11%), hypertension (59 vs 38%), CKD (5 vs. 12%), high school graduation (58 vs 80%), factor VIII (146 vs 124%), vWF (134 vs 113%), CRP (2.4 vs 1.8 mg/L) protein C (3.13 vs. 3.18 mg/L), all p <0.01. In age- and sex-adjusted Cox models, the relative risk of total VT for blacks vs. whites was 1.67 (95% CI 1.41, 1.97). When risk factors were added to age-, sex- and race-adjusted Cox models, BMI explained 36% of the excess risk of VT in blacks, factor VIII 58%, and vWF 54%. The other risk factors had a minimal impact on the HR for race. When all risk factors measured in both cohorts were considered in the same model, the association of black race with VT was attenuated (HR 1.15; 95% CI 0.94, 1.42). Of the risk factors evaluated, there were significant interactions between race and hypertension, CKD, and aPTT below the median (29s). The table lists the HR for each of these risk factors stratified by race; hypertension and CKD were stronger risk factors for VT in blacks while an aPTT less than the median was a stronger risk factor for VT in whites. Conclusions: Blacks have a higher incidence of VT than whites, whether provoked or unprovoked. The increased risk in blacks was largely explained by a greater prevalence of VT risk factors among blacks, particularly obesity, higher factor VIII and higher vWF. Further, CKD and hypertension were stronger risk factors for VT in blacks, while a shorter aPTT was a weaker risk factor for VT in blacks. Larger studies of VT in blacks addressing environmental and genetic risk factors and health-care disparities are needed to fully understand reasons for these ethnic differences in VT incidence. Disclosure: No relevant conflicts of interest to declare.

Among 29,701 Black and White participants aged 45 years and older in the Reasons for Geographic and Racial Difference in Stroke (REGARDS) study, allostatic load (AL) was defined as the sum score of established baseline risk-associated biomarkers for which participants exceeded a set cutoff point. Cox proportional hazard regression was utilized to determine the association of AL score with all-cause and cancer-specific mortality, with analyses stratified by body-mass index, age group, and race. At baseline, Blacks had a higher AL score compared with Whites (Black mean AL score: 2.42, SD: 1.50; White mean AL score: 1.99, SD: 1.39; p < 0.001). Over the follow-up period, there were 4622 all-cause and 1237 cancer-specific deaths observed. Every unit increase in baseline AL score was associated with a 24% higher risk of all-cause (HR: 1.24, 95% CI: 1.22, 1.27) and a 7% higher risk of cancer-specific mortality (HR: 1.07, 95% CI: 1.03, 1.12). The association of AL with overall- and cancer-specific mortality was similar among Blacks and Whites and across age-groups, however the risk of cancer-specific mortality was higher among normal BMI than overweight or obese participants. In conclusion, a higher baseline AL score was associated with increased risk of all-cause and cancer-specific mortality among both Black and White participants. Targeted interventions to patient groups with higher AL scores, regardless of race, may be beneficial as a strategy to reduce all-cause and cancer-specific mortality.

In South Africa, education is one of the social institutions manipulated by the apartheid government to develop and maintain an unequal society. In this provocative article, Es'Kia Mphahlele, a Black South African educator, describes the Blacks' struggle for educational improvement through alternative education. Mphahlele, who was forced into exile for two decades because of the stand he took against inferior education for Blacks, returned home to be part of a struggle for a system of education of which Blacks can take charge. He describes a vision of how alternative education in South Africa can draw from "the souls of people" and pave the way for a transformative and humane educational system for all people in the country.

Abstract Having more years of education is independently associated with lower mortality, but it is unclear whether other attributes of schooling matter. We examined the association of high school quality and all-cause mortality across race/ethnicity. In 1960, about 5% of US high schools participated in Project Talent (PT), which collected information about students and their schools. Over 21,000 PT respondents were followed for mortality into their eighth decade of life using the National Death Index. A school quality factor, capturing term length, class size, and teacher qualifications, was used as the main predictor. First, we estimated overall and sex-stratified Cox proportional hazards models with standard errors clustered at the school level, adjusting for age, sex, composite measure of parental socioeconomic status, and 1960 cognitive ability. Second, we added an interaction between school quality and race/ethnicity. Among this diverse cohort (60% non-Hispanic Whites, 23% non-Hispanic Blacks, 7% Hispanics, 10% classified as another race/s) there were 3,476 deaths (16.5%). School quality was highest for Hispanic respondents and lowest for non-Hispanic Blacks. Non-Hispanic Blacks also had the highest mortality risk. In the whole sample, school quality was not associated with mortality risk. However, higher school quality was associated with lower mortality among those classified as another race/s (HR 0.75, 95% CI: 0.56-0.99). For non-Hispanic Blacks and Whites, the HR point estimates were unreliable, but suggest that higher school quality is associated with increased mortality. Future work will disentangle these differences in association of school quality across race/ethnicity and examine cause-specific mortality.

This paper examines the interaction of education for both Blacks and Whites in all major religious groups on four key political issues: Abortion, gay marriage, feelings toward redistribution, and political party identification. We find that for most Blacks, race is the most salient factor across all four political dimensions; whereas there is significant variation by religion and education for Whites, there is very little difference for Blacks. As previous research has noted, Blacks are generally more conservative on gay marriage and Blacks are generally positive about redistribution, much more so than most Whites regardless of education and religion. We find education is more liberating to Whites than Blacks. The only issue for which education has significant effects for Blacks is abortion, but even in this case, unlike for Whites, there are not large religious differences among Blacks. This study corroborates previous research that abortion and gay marriage are less politically central to Blacks, who at all education levels are more likely to be Democrat than the most Democrat identified Whites.

This article examines the role of race in the patterns of incarceration of women in the state of Maryland during three critical periods: pre-Civil War, Civil War, and post-Civil War. Maryland, a border state, was wedged geographically and politically between the forces of slavery and abolition. In addition to race, the author identifies female offenders by examining place of birth, age, and occupation. The author supports the view that “plantation justice” was inapplicable to Blacks in Maryland. The author also suggests that the historical neglect of women in prison can be attributed to the small contribution of “native” White women to the total female prison population. Racial differences in why female offenders were incarcerated and how long they were sentenced are addressed. These differences are examined across the three time periods, noting the focus on controlling Blacks (free and slave), women, and immigrants.

AbstractThis exploratory study makes a contribution to the literature on antiracism by analyzing how first-generation French Blacks of sub-Saharan African descent practice everyday antiracism. In doing so, it expands the demographic terrain of this research to highlight some particularities in the experience of everyday racism and antiracism for ethnoracial minorities of immigrant origins. In addition to experiencing forms of racism encountered by both immigrants and other native ethnoracial minorities, first-generation French Blacks (like other non-White first-generation Europeans), face symbolic exclusion from the national community and delegitimization of their claims to Europeanness. Examining their experiences sheds light on how race, immigration, and national identity intersect to generate unique experiences of racism and antiracism. This paper also contributes to our understanding of how social context shapes the range of everyday antiracist strategies at a person's disposal. Specifically, integrating Kasinitz et al.'s (2008) framework for categorizing incidents of racial discrimination and prejudice with Fleming et al.'s (2010) categorization of responses to stigmatization, I present an analysis of antiracist responses that takes into account both the nature of the relationship between the victim and the perpetrator of racism (i.e., impersonal vs. personal) and the social context in which the encounter occurs (e.g., school, work, public space, etc). In doing so, I highlight how the conditions of a given incident of racism or discrimination set constraints on the range of antiracist responses an individual can practically (or feasibly) employ.

Purpose: National health statistics indicate that blacks have lower survival rates from colorectal cancer than do whites. This disparity has been attributed to differences in stage at diagnosis and other disease features, extent and quality of treatment, and socioeconomic factors. We evaluated outcomes for blacks and whites with rectal cancer who participated in randomized clinical trials of the National Surgical Adjuvant Breast and Bowel Project (NSABP). The randomized trial setting enhances uniformity in disease stage and treatment plan among all participants. Patients and Methods: The study included black (N = 104) or white (N = 1,070) patients from two serially conducted NSABP randomized trials for operable rectal cancer. Recurrence-free survival and survival were compared using statistical modeling to account for differences in patient and disease characteristics between the groups. Results: Blacks and whites had largely similar disease features at diagnosis. After adjustment for patient and tumor prognostic covariates, the black/white recurrence hazard ratio (HR) was 1.25 (95% confidence interval [CI], 0.94 to 1.66). The mortality HR was somewhat larger at 1.45 (95% CI = 1.09 to 1.93). Outcomes were improved for both groups in the more recent trial, which employed systemic adjuvant chemotherapy in all treatment arms. Conclusion: Recurrence-free survival was modestly less favorable for blacks, whereas overall survival was more disparate. Outcomes between groups were more comparable than those noted in national health statistics surveys and other studies. Adequate treatment access and the identification of new prognostic factors that can identify patients at high risk of recurrence are needed to ensure optimal outcomes for rectal cancer patients of all racial/ethnic backgrounds.

ABSTRACT Background Choline-related nutrients are dietary precursors of a gut microbial metabolite, trimethylamine-N-oxide, which has been linked to cardiometabolic diseases and related death. However, epidemiologic evidence on dietary choline and mortality remains limited, particularly among nonwhite populations. Objectives This study aimed to investigate the associations of choline-related nutrients with cardiometabolic and all-cause mortality among black and white Americans and Chinese adults. Methods Included were 49,858 blacks, 23,766 whites, and 134,001 Chinese, aged 40–79 y, who participated in 3 prospective cohorts and lived ≥1 y after enrollment. Cox regression models were used to estimate HRs and 95% CIs for cardiometabolic [e.g., ischemic heart disease (IHD), stroke, and diabetes] and all-cause deaths. To account for multiple testing, P values < 0.003 were considered significant. Results Mean choline intake among blacks, whites, and Chinese was 404.1 mg/d, 362.0 mg/d, and 296.8 mg/d, respectively. During a median follow-up of 11.7 y, 28,673 deaths were identified, including 11,141 cardiometabolic deaths. After comprehensive adjustments, including for overall diet quality and disease history, total choline intake was associated with increased cardiometabolic mortality among blacks and Chinese (HR for highest compared with lowest quintile: 1.26; 95% CI: 1.13, 1.40 and HR: 1.23; 95% CI: 1.11, 1.38, respectively; both P-trend < 0.001); among whites, the association was weaker (HR: 1.12; 95% CI: 0.95, 1.33; P-trend = 0.02). Total choline intake was also associated with diabetes and all-cause mortality in blacks (HR: 1.66; 95% CI: 1.26, 2.19 and HR: 1.20; 95% CI: 1.12, 1.29, respectively), with diabetes mortality in Chinese (HR: 2.24; 95% CI: 1.68, 2.97), and with IHD mortality in whites (HR: 1.31; 95% CI: 1.02, 1.69) (all P-trend < 0.001). The choline–mortality association was modified by alcohol consumption and appeared stronger among individuals with existing cardiometabolic disease. Betaine intake was associated with increased cardiometabolic mortality in Chinese only (HR: 1.16; 95% CI: 1.08, 1.25; P-trend < 0.001). Conclusions High choline intake was associated with increased cardiometabolic mortality in racially diverse populations.

Previous studies have shown that African Americans (blacks) tend to have higher nocturnal blood pressure than European Americans (whites). The study presented here was undertaken to determine whether treatment of hypertension influences nocturnal blood pressure differently in blacks than in whites. To answer this question, this study measured nocturnal blood pressure by ambulatory blood pressure monitoring (ABPM) in treated hypertensive blacks and whites whose daytime blood pressures were comparable. Inclusion criteria for this study were: diagnosis of essential hypertension, absence of renal failure, and documentation of antihypertensive therapy, diabetic status, proteinuria status, and body weight. All of the black patients in our programs who underwent ABPM and met the above criteria were included in this study. White patients were included on the basis of having the same inclusion criteria as blacks and showing, by ABPM, daytime mean arterial pressure (MAP) in the same range as that of the blacks selected for this study. The results of nocturnal blood pressure were unknown to the investigators when the patients were selected for this study. In the blacks (N = 62) and whites (N = 72) selected for study, the mean daytime (0600 to 2200 h) MAP was 107 +/- 1 SE mm Hg for both the black and white cohorts. To assess nocturnal blood pressure, the period from 0100 to 0500 h was chosen because it likely encompassed an interval of sleep, which is associated with the nadir of nocturnal blood pressure. This interval was termed 0100 to 0500 h, "middle night." Mean middle night MAP was 97 +/- 12 mm Hg in blacks versus 90 +/- 14 mm Hg in whites (P < 0.006, unpaired t test). The greater middle night MAP in blacks compared with whites was a result of the higher diastolic pressure in blacks (80 +/- 11 mm Hg) versus whites (75 +/- 11 mm Hg) (P = 0.003). Mean middle night systolic blood pressure was numerically higher in blacks than whites (131 +/- 18 mm Hg versus 128 +/- 17 mm Hg), but this difference did not achieve statistical significance. The higher middle night blood pressure in blacks versus whites could not be explained by differences between the groups in daytime MAP, age, gender, body weight, serum creatinine level, proteinuria, diabetic status, or greater use of short-acting antihypertensive agents in blacks versus whites. It was concluded that when treated hypertensive blacks and whites are matched for the same daytime blood pressure, blacks tend to have significantly higher nocturnal blood pressure than whites. The magnitude of this difference suggests that it could contribute importantly to the greater target-organ damage that is seen in hypertensive blacks compared with hypertensive whites.

Abstract Three kinds of carbon black, HAF (high abrasion furnace, N330), MT (medium thermal, N990), and graphitized MT were observed with the scanning tunneling microscope (STM), the transmission electron microscope (TEM), and the scanning electron microscope (SEM) All the STM images are formed from measurements of the x, t, and z position of points on the surface of the particle. The STM images of carbon blacks were compared to transmission electron microscope (TEM) photographs. Pitted and stepped bumps were observed on the surface of HAF carbon black. The surface of MT carbon black was more rough and disorganized At the atomic scale, ordered structure was found on the surface of HAF carbon-black particles Graphitized MT carbon-black particles were faceted polyhedra. Some facets were smooth while others had multiple terraces. The surface of graphitized MT carbon black was so well ordered that a lattice of carbon atoms similar to HOPG (highly ordered pyrolytic graphite) was observed on the smooth facets.
