Migration in migration-related diversity? The nexus between superdiversity and migration studies

This article argues that the notion of ‘superdiversity’ implies an investigation of diversity that goes well beyond the nature of migration origins and trajectories. To probe the academic value of superdiversity, I situate it within broader academic debates, suggesting that it is necessary to distinguish between superdiversity as a malleable social science concept – a set of variables that researchers conjunctively investigate – and superdiversity as a context in which these variables play out in complex social patterns. I argue that complexity is an integral aspect of superdiversity, before explaining how innovative research methods were used to investigate superdiversity in a dual-site project in London and Toronto in order to explore its relevance for global comparative research.     

Not all the same after all? Superdiversity as a lens for the study of past migrations

Due to its claim of contemporary exceptionalism, the notion of superdiversity raises suspicion among historians. However, historians would do well to not dismiss the entire superdiversity debate as more hype that does not concern them. As a multidimensional perspective on diversity, encouraging researchers to examine the interplay of many different factors that condition people's lives and to move beyond an ethno-focal perspective, superdiversity could be of interest to historians as well. This article shows how the notion can help historians debunk some of the homogenizing categories that tend to characterize the representation of past immigrant populations. The paper uses a superdiversity lens to examine migration to the city of Ghent from 1960 to 1980. It is an open invitation to historians to accept the challenges that superdiversity poses and to provide a proper historicization of the concept, thus furthering its theoretical development.     

A Doctor’s Testimony: Medical Neutrality and the Visibility of Palestinian Grievances in Jewish-Israeli Publics

This paper follows the testimony of Izzeldin Abuelaish, a Palestinian physician who bears witness to his experiences working, living, and suffering under Israeli rule. He presents his story as a doctor’s story, drawing on his identity as a medical professional to gain credibility and visibility and to challenge the limited legitimacy of Palestinian grievances. In this paper, I explore his testimony as a medical voice that at once recounts the suffering and loss endured by the Palestinian people and also struggles to negotiate the values associated with being a “reliable” witness. Consequently, I ethnographically examine the social life and reception of his story in Jewish-Israeli publics. In comparison with most Palestinian narratives, Abuelaish’s testimony achieved an extremely rare degree of visibility and sympathy, a phenomenon that calls out for analysis. I identify the boundaries that typically render Palestinian grievances invisible to Israeli publics and suggest how medicine’s self-proclaimed ethos of neutrality served as a channel for crossing them. Finally, I reflect on the political possibilities and limitations of medical witnessing to render suffering visible and arouse compassion toward those construed as a dangerous/enemy Other.     

Religious visibility: perceptions and experiences of residents in two Muslim concentration suburbs in Melbourne,Australia

In recent decades, and especially after the 9/11/2001 terrorist attack on US, an antipathy towards and fear of Muslim minorities in Western countries have increased, forming part of the current widespread anti-immigration sentiment. In this context, the ‘religiously visible’ Muslims are the most obvious target of negative perceptions, discrimination and other manifestations of ‘Islamophobia’. This paper uses quantitative and qualitative data on religious visibility collected through a survey and in-depth interviews in two suburbs with residential concentrations of Muslims in Melbourne, Australia. The two localities, ‘Broadburb’ and ‘Greenburb’, have similar proportions of Muslim residents (about 1/3) but the levels of religious visibility differ. The paper discusses perceptions and experiences of being religiously visible in a secular society, and particularly being a ‘visible Muslim’. We also discuss perceptions of Muslim visibility by others – non-visible Muslims and non-Muslims – who share neighbourhoods with the visible Muslim minority.     

New diversity,old anxieties in New Zealand: the complex identity politics and engagement of a settler society

Superdiversity signals the common experience in many countries and cities of the enhanced levels of diversity that are associated with contemporary immigration, yet there are a range of permutations and possibilities. One example of superdiversity – that of a particular group of settler societies represented by New Zealand – is explored, as the colonization of indigenous peoples has occurred alongside a nation-building project that centres on mass immigration, and which in turn has been layered by a more recent immigrant recruitment project that ostensibly values immigrants for the skills that they contribute to economic development. Since the 1970s, there have been limited but still important concessions made in terms of diversity recognition and group rights. This article explores the nature of this settler society superdiversity and its politics.     

Super-diverse street: a ‘trans-ethnography’ across migrant localities

This paper emerges from an ethnography of the economic and cultural life of Rye Lane, an intensely multi-ethnic street in Peckham, South London. The effects of accelerated migration into London are explored through the reshaping and diversification of its interior, street and city spaces. A ‘trans-ethnography’ is pursued across the compendium of micro-, meso- and macro-urban spaces, without reifying one above the other. The ethnographic stretch across intimate, collective and symbolic city spaces serves to connect how the restrictions and circuits of urban migration have different impacts and expressions in these distinctive but interrelated urban localities. The paper argues for a trans-ethnography that engages within and across a compendium of urban localities, to understand how accelerated migration and urban ‘super-diversity’ transform the contemporary global city.     

Interference between Conscious and Unconscious Facial Expression Information

There is ample evidence to show that many types of visual information, including emotional information, could be processed in the absence of visual awareness. For example, it has been shown that masked subliminal facial expressions can induce priming and adaptation effects. However, stimulus made invisible in different ways could be processed to different extent and have differential effects. In this study, we adopted a flanker type behavioral method to investigate whether a flanker rendered invisible through Continuous Flash Suppression (CFS) could induce a congruency effect on the discrimination of a visible target. Specifically, during the experiment, participants judged the expression (either happy or fearful) of a visible face in the presence of a nearby invisible face (with happy or fearful expression). Results show that participants were slower and less accurate in discriminating the expression of the visible face when the expression of the invisible flanker face was incongruent. Thus, facial expression information rendered invisible with CFS and presented a different spatial location could enhance or interfere with consciously processed facial expression information.     

Can Black‐and‐White Ruffed Lemurs (Varecia variegata) Solve Object Permanence Tasks?

We examined object permanence in black‐and‐white‐ruffed lemurs (Varecia variegata) at Zoo Atlanta. A series of visible and invisible displacement tasks with suitable controls were presented to five adult subjects. Subjects performed significantly above chance on all regular tasks, except for the double invisible displacements. Subjects failed visible and invisible controls. Failure on the control trials did not appear to be because subjects used the “last box touched” strategy (subjects did not choose the last box touched significantly more than expected by chance). However, a substantial percentage of choices was made to the last box touched by the experimenter. There was no significant difference between this percentage, and the percentage of choices made to the baited box (on both visible and invisible controls), which indicates that subjects were drawn to both boxes which the experimenter visited/touched, and thus failed the controls. Based on the results from the present study, we believe that there is no evidence that black‐and‐white ruffed lemurs understand visible and invisible tasks in the traditional object permanence battery.

City of Details: Interpreting the Personality of London

This article investigates the ways in which a group of enthusiasts for London constitute their city. The 'personality' attributed to London is described, as well as the interpretive acts that reveal it. These people, who also lead walking tours across the city, privilege 'detail' as their term of analysis. The article examines the identified qualities of that category, in particular its perceived capacity to animate the plural time-spaces of the city. This sensitivity to detail is presented as part of a sensing of place, which allows people to regard themselves as uniquely able to see the city. The article is intended as a contribution to the ethnography of London.     

Cortical responses to invisible faces: dissociating subsystems for facial-information processing

Perceiving faces is critical for social interaction. Evidence suggests that different neural pathways may be responsible for processing face identity and expression information. By using functional magnetic resonance imaging (fMRI), we measured brain responses when observers viewed neutral, fearful, and scrambled faces, either visible or rendered invisible through interocular suppression. The right fusiform face area (FFA), the right superior temporal sulcus (STS), and the amygdala responded strongly to visible faces. However, when face images became invisible, activity in FFA to both neutral and fearful faces was much reduced, although still measurable; activity in the STS was robust only to invisible fearful faces but not to neutral faces. Activity in the amygdala was equally strong in both the visible and invisible conditions to fearful faces but much weaker in the invisible condition for the neutral faces. In the invisible condition, amygdala activity was highly correlated with that of the STS but not with FFA. The results in the invisible condition support the existence of dissociable neural systems specialized for processing facial identity and expression information. When images are invisible, cortical responses may reflect primarily feed-forward visual-information processing and thus allow us to reveal the distinct functions of FFA and STS.     

Technical note: estimating sex using cervical canine odontometrics: a test using a known sex sample

The size of the permanent human canine tooth is one of the few sexually dimorphic features to be present in childhood and as such offers the opportunity to assist in the identification of sex in remains where no other appropriate criteria exist, such as in subadults. However, canine odontometrics are often associated with high levels of interobserver error and can be difficult to access if dentition is in situ. Additionally, appropriate points of measurement can be difficult to identify if the tooth is worn. Alternate measurements of the cervical canine diameters have been proposed as solutions to these issues, but the utility of these measurements in estimating sex has not been conclusively demonstrated. This study uses the buccolingual and mesiodistal cervical diameter of the canines from a known-sex sample from St. Bride's Church, London and a partially known-sex sample from the Old Church, Chelsea, London to classify individuals as male or female. A discriminant function classification using these diameters successfully identifies sex in 93.8% of the known-sex assemblage and 95% of the partially osteologically estimated sex assemblage. It is suggested that cervical canine diameters are highly repeatable measurements with low interobserver error, can be obtained on worn and in situ teeth, and provide as good or better guidance on estimating sex in human remains as standard maximal diameters.     

Delivering maternity services in an era of superdiversity: the challenges of novelty and newness

The population complexity associated with superdiversity brings a wide range of challenges for social welfare providers. Commentators have outlined concerns about the ability of service providers to meet the welfare needs of ever diversifying populations and point to potential problems in identifying the nature of need in rapidly changing superdiverse neighbourhoods as conventional approaches to consultation based around ethnicity become practically impossible. Using data collected in the West Midlands, which explored maternity service needs from the perspectives of new migrants and maternity professionals, some key barriers to effective welfare delivery in superdiverse areas are explored. The paper outlines the emergence of two challenges important in shaping new migrant access to maternity care in an era of superdiversity – novelty and newness – and proposes further research to examine the extent to which these challenges are faced in other social welfare services.     

Long-range visibility of greater sage grouse leks: a GIS-based analysis

We investigated whether male greater sage grouse, Centrocercus urophasianus, select lek locations on the basis of topographic features that affect their visibility to both conspecific females and a major avian predator, the golden eagle, Aquila chrysaetos. We mapped locations of displaying males at all leks in a local population and used a Geographic Information System (GIS) and digital elevation model (DEM) to generate ‘viewsheds’ around male locations within a boundary set by the estimated maximal visual acuity of the viewer. Areas visible around leks were compared to those visible around random sites with the same conformation of displaying males. Male sage grouse displayed at sites where surrounding topography both diminished long-range visibility (>1000 m) and enhanced short-range visibility (<500 m) to ground observers. These characteristics could (1) force eagles to monitor lek activity from the air, where they may be more visible to their prey, (2) make displaying males more visible to females and (3) allow males to monitor predators approaching the lek more easily. These results suggest that, in open habitats, visually signalling animals may exploit local topography to control both their visibility to receivers and the visibility of their immediate surroundings.     

Relationships between exhibit naturalism,animal visibility and visitor interest in a Chinese Zoo

Efforts to meet the welfare needs of captive animals (such as the provision of environmental enrichment and naturalistic furnishings) often compromise visitors’ needs (naturalistic exhibits often decrease the visibility of animals on display even though visitors pay to view them). The literature offers different predictions about how zoo visitors respond to decreased animal visibility in naturalistic exhibits but they require further evaluation. Further, visitor research is currently confined to Europe and America and studies outside these areas are limited. This paper investigates the relationships between exhibit naturalism, animal visibility and visitor interest in a Chinese Zoo. Visitor interest was observed at both naturalistic and barren exhibit designs. The study showed that the influence of animal presence on visitor behaviours was similar at both exhibit designs. Further, visitor interest was not compromised at the naturalistic exhibit when animals were not visible. The results demonstrate that the needs of animals and visitors can be balanced at naturalistic exhibits and support the transformation of exhibits to those representing naturalistic environments.     

THE VISIBILITY AND INVISIBILITY OF PRODUCTION AMONG SENEGALESE CRAFTSMEN

This article examines three social contexts of the production and exchange of craft objects in Senegal. In each context, the extent to which the production of craft items is visible or invisible varies, and these variations in turn affect the ways in which value is construed. These examples are understood as different 'regimes of value' (Appadurai), in whose constitution the production of craft objects, whether this is visible or invisible, plays a crucial role. The argument is that the concept of 'regime of value' needs to address more than simply the 'flow' of commodities, and must have regard for the organization of the relations between production, distribution, and consumption of craft objects. The article also frames these West African examples within a broader argument about the importance of the concept of production in order to redress the over-reliance of contemporary social theories on notions of consumption.     

Mexico through a superdiversity lens: already-existing diversity meets new immigration

New migration flows to Mexico are challenging long-established sociocultural configurations. So far, most studies on immigrants in Mexico have focused on singular ethno-national groups rather than paying attention to the intermingling of people. This paper presents an examination of diversification processes occurring in Guadalajara, Mexico. We contend that these are particularly strained because of the continuing frictions with which the country has to deal due to its already-existing diversity. The many forms of discrimination and racism that many Mexicans are subjected to by their co-nationals are often extended to new arrivals. The increasing complexity of migrant inflows challenges established forms of prejudice in everyday interactions. We argue in this paper that the use of superdiversity as a lens to study diversification processes allows us to better understand the changing dynamics currently taking place in Mexico.     

Variation in ultraviolet reflectance by carotenoid-bearing feathers of tanagers (Thraupini: Emberizinae: Passeriformes)

Avian visual sensitivity encompasses both the human visible range (400–700 nm) and also near‐ultraviolet (UV) wavelengths (320–400 nm) invisible to normal humans. I used reflectance spectrophotometry to assess variation in UV reflectance for yellow, orange and red plumage in 67 species of tanager (Passeriformes). Previous chemical studies, and my analysis of reflectance minima, suggest that carotenoids are the dominant pigments in yellow, orange and red tanager plumage. Spectra recorded over the range of wavelengths to which birds are sensitive (320–700 nm) were invariably bimodal, with both a plateau of high reflectance at longer (> 500 nm) wavelengths and a distinct secondary peak at UV (< 400 nm) wavelengths. Within this overall framework, variation in UV reflectance was expressed within well‐defined quantitative limits: (1) peak reflectance was always lower than the corresponding plateau of reflectance at longer visible wavelengths; (2) the intensity of peak reflectance declined steadily below 350 nm; (3) wavelengths of peak reflectance clustered between 350 and 370 nm. Significant correlations were detected between various measures of total reflectance in the UV and visible wavebands, but not between various measures of spectral location of UV and visible reflectance. I propose that the strong absorption band at short visible wavelengths (～ 380–550 nm) responsible for bimodal spectra of carotenoids in vitro is also responsible for bimodal reflectance by carotenoid‐based plumage colours. The construction of the UV and visible reflectance bands from different sides of this same absorbance band provides a mechanism for the observed covariation between UV and visible wavelengths. Lack of an association between the spectral locations of the UV and visible reflectance bands may result from the limited variation in spectral location of the UV band. These patterns suggest that plumage colours are subject to constraints, just as are more traditional morphological characters. © 2005 The Linnean Society of London, Biological Journal of the Linnean Society, 2005, 84 , 243–257.     

Commodity Fetichismo The Holy Spirit,and the turn to Pentecostal and African Independent Churches in Central Mozambique

Pentecostal and African Independent Churches have rapidly spread throughout central Mozambique in the aftermath of war and in the midst of a recent structural adjustment program that has hastened commoditization of community life and intensified local inequalities. This extraordinary expansion signals a shift away from reliance on “traditional” healers to treat persistent afflictions believed to have spiritual causes. Survey data and illness narratives collected from recent church recruits and local residents during research in 2002 and 2003 in the city of Chimoio reveal that healers have increased fees and tailored treatments to clients searching for good fortune in ways that have alienated many other help seekers in this changing social environment. While traditional healing has been celebrated in the international health world, community attitudes are less generous; many healers are increasingly viewed with suspicion because of their engagement with malevolent occult forces to foment social conflict, competition, and confrontation for high fees. Church healing approaches offer free and less divisive spiritual protection reinforced by social support in a new collectivity. One vital source of church popularity derives from pastors' efforts to tap the already considerable community anxiety over rising healer fees and their socially divisive treatments in an insecure environment.     

Defensive localism in white and black: a comparative history of European-American and African-American youth gangs

Despite the largely voluntary character of Nigerian immigration to the United States since 1970, it is not clear that their patterns of integration have emulated those of earlier immigrants who, over time, traded their specific national origins for “American” or “White” identities as they experienced upward mobility. This path may not be available to Nigerian immigrants. When they cease to be Nigerian, they may become black or African-American. In this paper, I use US Census data to trace patterns of identity in a Nigerian second-generation cohort as they advance from early school-age in 1990 to adulthood in 2014. The cohort shrinks inordinately across the period as its members cease to identify as Nigerian, and this pattern of ethnic attrition is most pronounced among the downwardly mobile – leaving us with a positively select Nigerian second generation and, perhaps, unduly optimistic assessments of Nigerian-American socioeconomic advancement.
