This paper examines a series of Schelling-like models of residential segregation, in which agents prefer to be in the minority. We demon- strate that as long as agents care about the characteristics of their wider community, they tend to end up in a segregated state. We then investigate the process that causes this, and conclude that the result hinges on the similarity of informational states amongst agents of the same type. This is quite di erent from Schelling-like behavior, and (...) sug- gests (in his terms) that segregation is an instance of macro behavior which can arise from a wide variety of micro motives.

The segregation of damaged components at cell division determines the survival and aging of cells. In cells that divide asymmetrically, such as Saccharomyces cerevisiae, aggregated proteins are retained by the mother cell. Yet, where and how aggregation occurs is not known. Recent work by Zhou and collaborators shows that the birth of protein aggregates, under specific stress conditions, requires active translation, and occurs mainly at the endoplasmic reticulum. Later, aggregates move to the mitochondrial surface through fis1‐dependent association. During replicative (...) aging, aggregate association with the mother‐cell mitochondria contributes to the asymmetric segregation of aggregates, because mitochondria in the daughter cell do not carry aggregates. With increasing age of mother cells, aggregates lose their connection to the mitochondria, and segregation is less asymmetric. Relating these findings to other mechanisms of aggregate segregation in different organisms, we postulate that fusion between aggregates and their tethering to organelles such as the vacuole, nucleus, ER, or mitochondria are common principles that establish asymmetric segregation during stress resistance and aging.

Residential racial and class segregation produce or exacerbate distributive injustice and political exclusion. Integration as the dispersal of a concentrated minority among the majority, however, often has its own harmful consequences. An alternative ideal of differentiated solidarity combines positive affinity grouping with non‐discrimination and regional government that encourages attention to shared problems and inequality.

Our aim is to cast light on socioeconomic residential segregation effects on life satisfaction. In order to test our hypothesis, we use survey data from Chile for the years 2011 and 2013. We use the Duncan Index to measure segregation based on income at the municipality level for 324 municipalities. LS is obtained from the CASEN survey, which considers a question about self-reported well-being. Segregation’s impact upon LS is not clear at first glance. On one hand, there (...) is evidence telling that segregation’s consequences are negative due to the spatial concentration of poverty and all the woes related to it. On the other hand, segregation would have positive effects because people may feel stress, unhappiness, and alienation when comparing themselves to better-off households. Additionally, there is previous evidence regarding the fact that people prefer to neighbor people of a similar socioeconomic background. Hence, an empirical test is needed. In order to implement it, we should deal with two problems, first, the survey limited statistical significance at the municipal level, hence we use the small area estimation methodology to improve the estimations’ statistic properties, and second, the double causality between segregation and LS; to deal with the latter, we include lagged LS as a regressor. Our findings indicate that socioeconomic segregation has a positive effect on LS. This result is robust to different econometric specifications. (shrink)

In this essay I defend the following prima facie argument: civic virtue is not dependent on integration and in fact may be best fostered under conditions of segregation. I demonstrate that civic virtue can and does take place under conditions of involuntary segregation, but that voluntary separation—as a response to segregation—is a more effective way to facilitate it. While segregation and disadvantage commonly coexist, spatial concentrations, particularly when there is a strong voluntary aspect present, often aid (...) in fostering civic virtue. Accordingly, so long as separation provides the conditions necessary for the promotion of civic virtue, integration is not an irreducible good. (shrink)

Efforts to understand gender segregation within and among science disciplines have focused on both supply- and demand-side explanations. Yet we know little about how academic scientists themselves view the sources of such segregation. Utilizing data from a survey of scientists at thirty top U.S. graduate programs in physics and biology and semistructured interviews with 150 of them, this article examines the reasons academic scientists provide for differences in the distribution of women in biology and physics. In quantitative analyses, (...) gender is more salient than discipline in determining the reasons scientists provide for gender disparities between disciplines, suggesting that gender may act as a “master status,” shaping the experiences of scientists regardless of the gender composition of the discipline. Qualitative interviews confirm this interpretation and reveal that scientists also perceive mentoring, natural differences, discrimination, and the history of the disciplines to be important factors. Results contribute to research on the relationship between emotional labor and occupational gender segregation conducted in professions such as law and nursing. (shrink)

This commentary considers how far one can go in making inferences about functional modularity or segregation, based on the sorts of analyses used by Caplan & Waters in relation to the underlying neuronal infrastructure. Specifically, an attempt is made to relate the “functionalist” approach adopted in the target article to “neuroreductionist” perspectives on the same issue.

In this chapter I consider the place of the topic of racial and ethnic urban residential segregation factors into political philosophy. I begin with a short history of residential segregation and the ghetto, and their role in systems of racial domination and oppression, and remarks on the general neglect of this topic in contemporary political philosophy, including in nonideal political philosophy, which proports to take on examples of real-world injustices and inequalities. I then examine, from the standpoint of (...) liberal-egalitarian political theory, what segregation, as a concept, entails, and its harms to individuals, communities, and societies. Segregation in all its forms (residential, educational, and employment, as well as in political and legal systems) is an instance of injustice and inequality and a major component of processes that maintain injustice and inequality, so it requires correction and rectification of some sort. Desegregation and integration are typically forwarded as solutions to the ills and injustices of segregation. They seem synonymous, but are they? To answer this question, I survey the prominent conceptualizations of both during the civil rights movement and the contemporary debate over those terms and political theoretical positions. In the conclusion I outline my partial defense of the idea of integration. (shrink)

The precise 1:1 segregation of Mendelian heredity is ordinarily taken for granted, yet there are numerous examples of ‘cheating’ genes that perpetuate themselves in the population by biasing the Mendelian process in their favor. One example is the Segregation Distortion system of Drosophila melanogaster, in which the distorting gene causes its homologous chromosome to produce a nonfunctional sperm. This system depends on three closely linked components, whose molecular basis is beginning to be understood.The system is characterized by numerous (...) modifiers changing the degree of distortion. Mathematical theory shows that unlinked modifiers that change the degree of distortion in the direction of Mendelism always increase in the population. This provides a mechanism for removing cheaters and preserving the honesty of the Mendelian gene‐shuffle. (shrink)

Data sharing between housing and education agencies will provide housing agencies with resources to assist them with efforts to decrease segregation and mitigate the adverse health outcomes experienced by people of color. The Fair Housing Act has the potential to fulfill its original integrationist purpose if housing and education agencies combine resources and data to create and implement fair housing plans. The Biden Administration’s restored rule to affirmatively further fair housing pursuant to the Fair Housing Act of 1968 which (...) seeks to reduce segregation and increase housing equity. However, it omits most of the processes set forth by the Obama Administration whereby federal agencies provide the proper tools to housing agencies so that they are able to make data-based decisions about housing policies. This article advocates for the sharing of data between housing and education agencies to optimize the positive impact of fair housing not only within housing, but also on the education, employment, and health opportunities for communities of color.

In this book I argue that school integration is not a proxy for educational justice. I demonstrate that the evidence consistently shows the opposite is more typically the case. I then articulate and defend the idea of voluntary separation, which describes the effort to redefine, reclaim and redirect what it means to educate under preexisting conditions of segregation. In doing so, I further demonstrate how voluntary separation is consistent with the liberal democratic requirements of equality and citizenship. The position (...) I defend is not opposed to integration but rather is a justified response to the daily experience of frustration and disappointment with a system that has failed members of marginalized groups for too long. I argue that most voluntary separation experiments in education, far from being motivated by a sense of racial, cultural or religious exclusion, are in fact driven among other things by a desire for a quality education, not to mention community membership and self respect. As such, voluntary separation represents a morally robust pragmatic strategy that is able to answer liberal challenges concerning involuntary stratification, ethnocentrism and democratic deliberation.

Concern has been raised that segregation of girls and boys into separate classes leads to increased gender stereotyping. We tested this in a sample of 365 seventh-grade students attending a junior high school that offers both gender-segregated (GS) and co-educational classes. It was found that for both boys and girls, the more GS classes they took in the fall, the more gender stereotyped they were in their responding in the spring (controlling for initial levels of gender stereotyping). We concluded (...) that GS likely heightens the salience of gender in the classroom thereby reinforcing and increasing gender stereotypes. As such, we argue that GS is a misguided approach to addressing any educational difficulties girls and boys might be having. (shrink)

Fringe benefits have been neglected as a source of job-induced gender inequality. Among full-time, private sector workers in the United States in 1979, women's health insurance coverage rate was 12 percentage points lower than men's. This article considers three models to explain such gender differences in the receipt of fringe benefits: the direct discrimination model, the occupational segregation model, and the industrial segregation model. Using data from the May 1979 Current Population Survey Supplement, we found the magnitude of (...) the gender gap in health insurance coverage in the United States to be related to industrial differences. We argue that industrial segregation of women workers may be more important than occupational segregation in determining gender differences in work rewards. (shrink)

This study attempts to analyse socio-economic segregation in three metropolitan areas of Lithuania. Indexes of segregation, dissimilarity and isolation were analysed trying to reveal different aspects of socio-spatial segregation in the urban regions, which experienced major shifts in their occupational structure over the last decades. The main occupational groups were used as a proxy for the socio-economic status. Data from 2001 and 2011 censuses was used to investigate segregation processes in the metropolitan areas and their main (...) structural zones – urban cores and suburbs. Notwithstanding major economic and social changes of the post-communist society, all measured indexes indicated low levels of segregation and limited changes during the analysed period. The results showed that the fastest increase of segregation was in the capital city. It was also revealed that the rich­est groups of population are the most segregated, and they tend to live more and more separately from other groups. The differences in the concentration of high and low status occupational groups and the changes in those patterns were illustrated in the maps. (shrink)

Zygote cytokinesis produces two symmetric blastomeres, which contain one copy of each parental genome. Contrary to this dogma, we recently discovered that mammalian zygotes can spontaneously segregate entire parental genomes into different blastomeres and coined this novel form of genome segregation heterogoneic division. The molecular mechanisms underlying the emergence of blastomeres with different parental genomes during the first mitotic cycle remain to be elucidated. Here, we speculate on which parental genome asymmetries could provide a mechanistic foundation for these remarkable (...) zygote divisions. In reviewing the field and considering our findings, we revisit the architecture of the first zygotic metaphase by invoking asymmetric interactions between the mitotic spindle and the parental kinetochores. We also speculate on how asynchronous parental cell cycles can be a source of heterogoneic zygote divisions through the formation of parental genome private spindles. (shrink)

This article explores the recent urban transformations of downtown Cairo, in particular around the area of Mohammed Mahmud Street and Tahrir Square, after a year and a half of violent confrontations between the protesters and the military junta. The article first looks at how these confrontations led to the segregation of the city through the use of buffer-concrete walls, army tanks, check-points and barbed-wire barricades that made life for its inhabitants impossible. The squeezing of Tahrir and its surroundings created (...) mostly a delineated and restricted war zone. This was undertaken after a series of killings and massacres took place. The article reflects upon the explosion of sardonic graffiti and epic murals that followed these events as a vibrant expression of dissenting street art, as well as the creation of a memorial space.

Communities of nuclear workers have evolved in distinctive contexts. During the Manhattan Project the UK, USA and Canada collectively developed the first reactors, isotope separation plants and atomic bombs and, in the process, nurtured distinct cadres of specialist workers. Their later workplaces were often inherited from wartime facilities, or built anew at isolated locations. For a decade, nuclear specialists were segregated and cossetted to gestate practical expertise. At Oak Ridge Tennessee, for example, the informal ‘Clinch College of Nuclear Knowledge’ aimed (...) to industrialise the use of radioactive materials. ‘We were like children in a toy factory’, said its Director: ‘everyone could play the game of designing new nuclear power piles’. His counterpart at Chalk River, Ontario headed a project ‘completely Canadian in every respect’, while the head of the British project chose the remote Dounreay site in northern Scotland because of design uncertainties in the experimental breeder reactor. With the decline of secrecy during the mid-1950s, the hidden specialists lauded as ‘atomic scientists’ gradually became visible as new breeds of engineers, technologists and technicians responsible for nuclear reactors and power plants. Mutated by their different political contexts, occupational categories, labour affiliations, professional representations and popular depictions, their activities were disputed by distinct audiences. This chapter examines the changing identities of nuclear specialists and the significance of their secure sites. Shaped successively by Cold War secrecy, commercial competition and terrorist threats, nuclear energy remained out of site for wider publics and most nuclear specialists alike. The distinctive episodes reveal the changing working experiences of technical workers in late-twentieth and early twenty-first century environments. (shrink)

In this essay I develop W.E.B. Du Bois’s concept of double consciousness to demonstrate the limitations of Kant’s and Rawls’s models of self-respect. I argue that neither Kant nor Rawls can explain what self-respect and resistance to oppression warrants under the conditions of violent and systematic racial exclusion. I defend Du Bois’s proposal of voluntary black self-segregation during the Jim Crow era and explain why Du Bois believes that the black American community has a moral right to assert its (...) self-respect by mitigating exposure to racial violence and animus in a white-controlled polity.

L’article met en lumière la persistance du système de valeurs au cœur de la ségrégation des personnes handicapées et la manière dont il oriente/alimente le droit international. Analysant les réponses institutionnelles au handicap, il montre en quoi les droits humains contemporains offrent un cadre propice au changement social et au processus de désinstitutionnalisation. Dans un premier temps, l’auteure montre qu’une conception du handicap fondée sur le modèle médical fait de la validité/capacité la norme sociale. L’article se penche ensuite sur la (...) Convention relative aux droits des personnes handicapées et le modèle de handicap fondé sur les droits humains, qui est fondamental pour sa mise en œuvre.

Enfin, le document montre comment et pourquoi l’institutionnalisation des personnes handicapées constitue une ségrégation et un déni fondamental des droits humains. (shrink)

This article offers an account of organizational change to explain why women leaders are underrepresented compared to women athletes in many sports organizations. I distinguish between accommodation and transformation as forms of change: the former includes women without challenging binary constructions of gender, the latter transforms an organization’s gendered logic. Through a case study of the International Olympic Committee from 1967-1995, I trace how the organization came to define gender equity primarily in terms of accommodating women’s segregated athletic participation. Key (...) to this was the construction of women’s bodies as athletically able but inferior to men, an arrangement formalized in codified rules and procedures and legitimized by external stakeholders. Defined in these terms, gender equity did little to transform the organization’s binary and hierarchically gendered logic, which continued to shape the informal norms and procedures associated with the organization’s allegedly gender-neutral and meritocratic yet male-dominated leadership. I argue that the exclusion of women from ostensibly gender-integrated leadership positions allows organizations to avoid revealing gender similarity between men and women. This maintains a logic underpinned by notions of binary gender difference and masculine superiority. (shrink)

In this paper, I show that there is a bidirectional relationship between gender-based social norms and gender-segregated education policies that excludes girls from knowledge production within the Iranian school system. I argue that gender segregation in education reproduces hermeneutic inequality through the reinforcement of epistemic segregation as a form of epistemic injustice. In particular, I focus on gender-based instructional epistemic injustice, which refers to a set of epistemic practices that actively exclude a student or an education professional in (...) their capacity as a knower from the process of knowledge production within an education system based on gender dynamics, roles, norms, or expectations. This, in addition, has an impact on schoolboys through the reproduction of active ignorance. I conclude that in societies such as Iran, where highly gendered norms play out in the school system and are further reinforced by that system, the result is not limited to gender segregation itself, but extends beyond it to a form of epistemic injustice that wrongs students by reproducing and reinforcing those highly gendered norms.

This essay introduces a special report from The Hastings Center entitled Democracy in Crisis: Civic Learning and the Reconstruction of Common Purpose, which grew out of a project supported by the John S. and James L. Knight Foundation. This multiauthored report offers wide‐ranging assessments of increasing polarization and partisanship in American government and politics, and it proposes constructive responses to this in the provision of objective information, institutional reforms in government and the electoral system, and a reexamination of cultural and (...) political values needed if democracy is to function well in a pluralistic and diverse society. The essays in the special report explore the norms of civic learning and institutions, social movements, and communal innovations that can revitalize civic learning in practice. This introductory essay defines and explains the notion of civic learning, which is a lynchpin connecting many of the essays in the report. Civic learning pertains to the ways in which citizens learn about collective social problems and make decisions about them that reflect the duties and responsibilities of citizenship. Such learning can occur in many social settings in everyday life, and it can also be facilitated through participation in the processes of democratic governance on many levels. Civic learning is not doctrinaire and is compatible with a range of public goals and policies. It is an activity that increases what might be called the democratic capability of a people. (shrink)

This research critically analyses patriarchal practices of male family members in terms of social relationships in businesses of women. The extant literature, which seeks to explore the negative influences of the family on women’s entrepreneurship, mostly revolves around the impact of patriarchal segregation of work on businesses. As such, it concentrates almost exclusively on the aspect of material gains through domestic responsibilities and childcare of women at the household sphere. This feminist study takes the debate forward with novel insights (...) on how menfolk of the family dominate, oppress and exploit women by directly getting involved in small businesses of women in a highly patriarchal developing nation, Bangladesh. From the interviews of the women business-owners, it is established that businesses of some women are adversely affected by male relatives’ social practices that are not tied to the domestic modes of production. Thus, the article significantly contributes to the understanding on gender subordination in women’s entrepreneurship from the narrow concentration on material gains of male family members to a more nuanced view of social practices.

Previous research on gender-based economic inequality has emphasized occupational segregation as the leading explanatory factor for the gender wage gap. Yet the globalization of the U.S. economy has affected gender inequality in fundamental ways and potentially diminished the influence of occupational gender segregation. We examine whether occupational gender segregation continues to be the main determinant of gender earnings inequality and to what extent globalization processes have emerged as important determinants of inequality between women’s and men’s earnings. We (...) study factors contributing to the gender earnings ratio as well as the median earnings of men and women for 271 U.S. metropolitan areas. The results indicate that occupational segregation is still the leading determinant of gender earnings inequality, that its effects are only slightly diminished by the presence of globalization, and that various aspects of the global economy independently influence the gender earnings gap.

Recent research indicates that among young women, Blacks have lower employment rates than whites. Evidence is provided about whether young Black women's lower employment rates stem from structural features of the labor market, discrimination, or changing family or individual characteristics. Data show that Black women exit full-time employment at higher rates because they are more likely to be laid off, to leave because they work in temporary/seasonal jobs, and to leave for other reasons. Structural features of the labor market are (...) key in explaining Black women's higher rates of lay-offs, exits from temporary/seasonal work, and exits for other reasons. Individual characteristics and discrimination play a role in Black women's higher rates of lay-offs and exits for other reasons while family characteristics are important in explaining Black women's higher rates of leaving temporary/seasonal work and leaving for other reasons. Evidence suggests that Black women's higher exit rates are indicative of disadvantage in the labor market. (shrink)

Rosa Parks was arrested in 1955 for refusing to submit to Alabama law requiring racially segregated transport. Her arrest triggered the Montgomery bus boycott. Fred Gray, barely a year out of law school, represented her – and for nearly half a century thereafter played a prominent role in almost every major civil rights case in the state. Gray’s key moral and legal commitment was grounded in opposition to segregation of every kind, based on the law in principle and the (...) US Constitution in particular. The early Gray was an idealist who advocated integration as the best means to break down segregation. The elder Gray, by contrast – even while rejecting black‐nationalist calls for separatism – reflects an ideological shift away from untrammelled support for integration as such, to a more explicit focus on protecting the interests of the black community through the preservation of its institutions.

Latent in John Rawls’s discussion of envy, resentment and voluntary social segregation is a plausible (partial) explanation of two striking features of contemporary American life: (1) widespread complacency about inequality and (2) decreased political participation, especially by the least advantaged members of society.

A purely kinematic theory of movement runs the risk of having no explanatory power because it neglects the internal generative structures of the central nervous system. Distributed interaction between the agonist and antagonist systems would better simulate physiological mechanisms of oscillation, lateral inhibition, and synchronization, all of which have important roles in motor control.

Many supporters of open borders argue that restrictions on immigration are unjust in part because they undermine equal opportunity. Borders prevent the globally least-advantaged from pursuing desirable opportunities abroad, cementing arbitrary facts about birth and citizenship. In this paper I advance an argument from equal opportunity to global freedom of movement. In addition to preventing people from pursuing desirable opportunities, borders also create a prone, segregated population that can be dominated and exploited. Restrictions on mobility do not just trap people (...) in bad opportunity sets—they help create bad opportunities by isolating the negative externalities of production and foreign policy. Freedom of movement can play a vital role in spreading risks and burdens, incentivizing their mitigation. Using an analysis of feudalism, segregation, and the transnational economy, I illustrate the centrality of space and mobility, showing why freedom of movement is a necessary tool for preventing political and economic oppression.

The diversity of multicultural, multi-religious, and multi-ethnic groups and communities within Britain has created cohesion and integration challenges for different community groups and authorities to adapt to the current diverse society. More recently, there has been an increased focus on Muslim segregation in Britain in official reports and reviews. Those documents mentioned the Muslims’ segregation (directly or indirectly) for various reasons, and some recommendations have aimed to improve “community cohesion” in general and Muslims’ “integration” in particular. However, community (...) participation in the design or planning of regeneration and development projects has yet to be focused on, although these documents recommended promoting community cohesion and integration through these projects. Community participation in architecture—in its broader sense—is a crucial aspect that contributes towards fulfilling the tasks of serving communities with different religious and ethnic backgrounds. Muslims’ religious and cultural practices have been problematised in urban spaces and perceived as leading to social and spatial segregation. This paper intends to explore how secular urban spaces are used and perceived by Muslims through their religious and cultural practices. Therefore, the article aspires to inform the community participation in urban projects and demonstrates the role that Muslims’ inclusion in designing urban projects has in promoting cohesion and integration. The Ellesmere Green project in Burngreave, Sheffield, UK, is an empirical example of exploring this locally through semi-structured interviews with community members, leaders, and local authorities’ officials. The findings demonstrate that sacred and secular spaces are interconnected in Muslims’ everyday lives, and the boundaries between them are blurry. The data also show that having the ability to manifest their religious and cultural practices in secular urban spaces does not suggest the desire for segregation, nor does it reduce Muslims’ willingness to have social and spatial interactions with non-Muslims.

Auditory scene analysis is critical for complex auditory processing. We study auditory segregation from the neural network perspective, and develop a framework for primitive auditory scene analysis. The architecture is a laterally coupled two‐dimensional network of relaxation oscillators with a global inhibitor. One dimension represents time and another one represents frequency. We show that this architecture, plus systematic delay lines, can in real time group auditory features into a stream by phase synchrony and segregate different streams by desynchronization. The (...) network demonstrates a set of psychological phenomena regarding primitive auditory scene analysis, including dependency on frequency proximity and the rate of presentation, sequential capturing, and competition among different perceptual organizations. We offer a neurocomputational theory—shifting synchronization theory—for explaining how auditory segregation might be achieved in the brain, and the psychological phenomenon of stream segregation. Possible extensions of the model are discussed. (shrink)

Online social networks captured the attention of the masses by offering attractive means of sharing personal information and developing social relationships. People expose personal information about their lives on OSNs. This may result in undesirable consequences of users’ personal information leakage to an unwanted audience and raises privacy concerns. The issue of privacy has received a significant attention in both the research literature and the mainstream media. In this paper, we present results of an empirical study that measure users’ attitude (...) towards interpersonal privacy concerns in OSNs. The results demonstrated a serious mismatch between privacy concerns of users and their information sharing behavior. In addition, it indicated that strangers are part of user social circles, this makes privacy protection more complicated, and introduce an insider threat, whereas all existing privacy tools allow users to manage the outsider threat. Information and friend segregation strategies are suggested on the basis of user information disclosure and interaction pattern. We conclude that sensitivity of information and frequency of interaction, both, play a vital role in information and friend segregation. (shrink)

It is argued that the alleged cases of cognitive penetration of visual modules actually arise from the integration of information among different modules. This would reflect a general computational strategy according to which constraints to a particular module would be provided by information coming from different modules. Examples are provided from the integration of stereopsis and occlusion and from computation of motion direction.

Asymmetric cell division generates cell diversity and contributes to cellular aging and rejuvenation. Here, we review the molecular mechanisms enabling budding yeast to recognize spindle pole bodies (SPB, centrosome equivalent) based on their age, and guide their non‐random mitotic segregation: SPB inheritance requires the distinction of old from new SPBs and is regulated by the SPB‐inheritance network (SPIN) and the mitotic exit network (MEN). The SPIN marks the pre‐existing SPB as old and the MEN recognizes these marks translating them (...) into spindle orientation. We next revisit other molecules and structures that partition depending on their age rather than their abundance at mitosis as, for example, DNA, centrosomes, mitochondria, and histones in yeast and other systems. The recurrence of this differential behavior suggests a functional significance for numerous cell types, which we then discuss. We conclude that non‐random segregation may facilitate asymmetric cell fate determination and thereby indirectly aging and rejuvenation. (shrink)

Most research about race has been influenced by values of one sort or another. This started with the inception of race as a biological category. Cognitive values about race were concerned with the worth of distinctive taxonomic divisions, and political values about it were concerned with the moral, aesthetic, and political meanings of these human distinctions. The presence of cognitive and non‐cognitive values in contemporary social science concerning race is no less present or important. The role of racial politics is (...) exposed in the debate over the nature of contemporary residential housing patterns, as well as in examinations of the methods and measures of segregation research. Such examinations uncover not only a sociology of the segregation studies, but also certain values about race and segregation. This leads us to richer explanations, given our public political desires, than we would have without those values. (shrink)
