The human face holds a privileged position in multi-disciplinary research as it conveys much information—demographical attributes (age, race, gender, ethnicity), social signals, emotion expression, and so forth. Studies have shown that due to the distribution of ethnicity/race in training datasets, biometric algorithms suffer from “cross race effect”—their performance is better on subjects closer to the “country of origin” of the algorithm. The contributions of this paper are two-fold: (a) first, we gathered, annotated and made public a large-scale database of (over 175,000) facial images by automatically crawling the Internet for celebrities’ images belonging to various ethnicity/races, and (b) we trained and compared four state of the art convolutional neural networks on the problem of race and ethnicity classification. To the best of our knowledge, this is the largest, data-balanced, publicly-available face database annotated with race and ethnicity information. We also studied the impact of various face traits and image characteristics on the race/ethnicity deep learning classification methods and compared the obtained results with the ones extracted from psychological studies and anthropomorphic studies. Extensive tests were performed in order to determine the facial features to which the networks are sensitive to. These tests and a recognition rate of 96.64% on the problem of human race classification demonstrate the effectiveness of the proposed solution.

The Impact

The term “race” refers to groups of people who have differences and similarities in biological traits deemed by society to be socially significant, meaning that people treat other people differently because of them. Meanwhile, ethnicity refers to shared cultural practices, perspectives, and distinctions that set apart one group of people from another. Ethnic differences are not inherited; they are learned. When racial or ethnic groups merge in a political movement as a form of establishing a distinct political unit, then such groups can be termed nations that may be seen as representing beliefs in nationalism. Race and ethnicity are linked with nationality particularly in cases involving transnational migration or colonial expansion. Anthropologists and historians, following the modernist understanding of ethnicity, see nations and nationalism as developing with the rise of the modern state system. They culminated in the rise of “nation-states,” in which the presumptive boundaries of the nation coincided with state boundaries. Thus, the notion of ethnicity, like race and nation, developed in the context of European colonial expansion, when mercantilism and capitalism were promoting global movements of populations at the same time that state boundaries were being more clearly and rigidly defined. Theories about the relation between race, ethnicity, and nationality are also linked to more general ideas about the impact of genomics on social life—ideas that often refer to the growing “geneticization” of social life.

The Impact

The impact of race, ethnicity, and sexual orientation on human cognition, affect, and behavior has been well documented in the psychology, sociology, and counseling literature. Sport and exercise psychology, however, has minimized the importance of these variables (Duda & Allison, 1990). The purpose of the current study was to determine how race, ethnicity, and sexual orientation have been addressed in the recent sport and exercise psychology literature. Duda and Allison’s previous research was replicated and extended by analyzing the content of 982 manuscripts published in JSEP, JASP, and TSP between 1987 and 2000. Overall, 19.86% of manuscripts included references to race/ethnicity and 1.22% included references to sexual orientation. Detailed results demonstrate that, despite an increase in the number of papers that include references to race and ethnicity, there has been no systematic attempt to include the experience of marginalized groups in the literature. Researchers and practitioners are encouraged to incorporate appropriate questions, reporting, and sensitivity with regard to race, ethnicity, and sexual orientation into their work.

The Impact

Persistent white–black disparities in education outcomes, combined with the growing presence of Asian American and especially Latino children, will make race and ethnicity a core element of education policy in the United States in the twenty-first century. This chapter explores, without resolving, a series of questions at the intersection of race, ethnicity, and American education policy. We review research evidence on persistent racial achievement gaps, race and school choice, the impact of No Child Left Behind, urban school governance, segregation, and the role of the courts in desegregation and school finance. We find that most questions about the best policies on these topics have no clear answers for several reasons explored in the chapter. Furthermore, future research must be reconceptualized since standard assumptions about group boundaries and group interests warrant reexamination. The study of education needs better data, improved methodologies, closer attention to class dynamics, and less partisan scholarship.

The Impact

Over the years, a distinct body of research has emerged that examines procedural justice in problem-solving courts. However, there is virtually no research to date on racial and ethnic differences in perceptions of procedural justice among problem-solving court clients. The present study seeks to understand the complexities of judicial procedural justice and race/ethnicity within problem-solving courts. Using a convenience sample of 132 clients from two problem-solving courts in a southern state, this study addresses a void in the literature by examining the influence of race/ethnicity on perceptions of procedural justice as well as the impact of race/ethnicity and procedural justice on clients’ likelihood of recidivism. Results suggest that Black problem-solving court clients’ have significantly lower perceptions of procedural justice, while also having a lower likelihood of recidivism. Perceptions of procedural justice did not influence recidivism outcomes. Policy implications and recommendations for future research are discussed.

The Impact

The study of race, ethnicity, crime, and justice usually involves research on racial and ethnic differences in crime and justice patterns or the overrepresentation of racial and ethnic minorities in the criminal justice system. Despite recognition that racial and ethnic variations in crime and justice exist, our knowledge on the sources and consequences of this linkage is incomplete. In part this is because the categories of race and ethnicity are evolving. Also, some of the racial and ethnic categories reported by criminal justice agencies are limited or require refinement. For example, some agencies do not always use the same racial and ethnic categories, particularly with respect to Latinos/Hispanics, and code victims or offenders as either white or black. Nevertheless, although current knowledge is limited, there is still a large body of research on the relationships among race, ethnicity, crime, and justice. Criminologists tend to favor examining the impact of racial or ethnic composition, net of other social and economic factors, on violent crimes such as homicide across cities, or they will examine racial- or ethnic-specific outcomes across communities. Some social scientists also examine the effects of race and ethnicity by examining the relationship between the police and racial and ethnic minorities, or perhaps variations in sentencing and incarceration in prisons, jails, and halfway houses. However one chooses to examine race, ethnicity, crime, and justice, there are considerable racial and ethnic disparities concerning this topic across the United States.

Racial Ethnic

Despite growing evidence that COVID-19 is disproportionately affecting communities of color, state-reported racial/ethnic data are insufficient to measure the true impact. We found that between April 12, 2020, and November 9, 2020, the number of US states reporting COVID-19 confirmed cases by race and ethnicity increased from 25 to 50 and 15 to 46, respectively. However, the percentage of confirmed cases reported with missing race remained high at both time points (29% on April 12; 23% on November 9). Our analysis demonstrates improvements in reporting race/ethnicity related to COVID-19 cases and deaths and highlights significant problems with the quality and contextualization of the data being reported. We discuss challenges for improving race/ethnicity data collection and reporting, along with opportunities to advance health equity through more robust data collection and contextualization. To mitigate the impact of COVID-19 on racial/ethnic minorities, accurate and high-quality demographic data are needed and should be analyzed in the context of the social and political determinants of health.

Abstract Introduction Preparations of health systems to accommodate large number of severely ill COVID-19 patients in March/April 2020 has a significant impact on nuclear medicine departments. Materials and Methods A web-based questionnaire was designed to differentiate the impact of the pandemic on inpatient and outpatient nuclear medicine operations and on public versus private health systems, respectively. Questions were addressing the following issues: impact on nuclear medicine diagnostics and therapy, use of recommendations, personal protective equipment, and organizational adaptations. The survey was available for 6 days and closed on April 20, 2020. Results 113 complete responses were recorded. Nearly all participants (97 %) report a decline of nuclear medicine diagnostic procedures. The mean reduction in the last three weeks for PET/CT, scintigraphies of bone, myocardium, lung thyroid, sentinel lymph-node are –14.4 %, –47.2 %, –47.5 %, –40.7 %, –58.4 %, and –25.2 % respectively. Furthermore, 76 % of the participants report a reduction in therapies especially for benign thyroid disease (-41.8 %) and radiosynoviorthesis (–53.8 %) while tumor therapies remained mainly stable. 48 % of the participants report a shortage of personal protective equipment. Conclusions Nuclear medicine services are notably reduced 3 weeks after the SARS-CoV-2 pandemic reached Germany, Austria and Switzerland on a large scale. We must be aware that the current crisis will also have a significant economic impact on the healthcare system. As the survey cannot adapt to daily dynamic changes in priorities, it serves as a first snapshot requiring follow-up studies and comparisons with other countries and regions.
