Journal articles on the topic 'Segregationist identity'

This article considers protest poetry written between 1961 and 1976. I argue that the Soweto poetry of the 1970s enabled activism that would change Johannesburg’s landscape, facilitating the racial mixing of inner city areas and eroding the segregationist policies that had defined the city from its beginnings. Concomitantly, the paper focuses on representations of the train as a site through which black localities were produced as resistance. Via close readings of poetry by Mbuyiseni Oswald Mtshali, Sipho Sepamla, and Mongane Wally Serote, I show how the train establishes Soweto as a “neighbourhood”, while also constructing a white “other” against which its identity is affirmed.

North Macedonia’s two main ethnic groups, the Albanians and Macedonians, have experienced increasing segregation in education, though recent political shifts have made social cohesion a priority, which could replace decades of segregationist policies and break down a damaging cycle of segregation. Using a qualitative approach, I examine the complex relationship between policies, schools, and individuals through analysing 18 years of education policies, interviews/focus groups with 30 participants, and four years living and working in segregated communities. To explore how educational policies, institutions, and practices perpetuate ethnic segregation in North Macedonia, and how growing up in a divided society shapes individuals’ conceptions of themselves and other predominant ethnic groups, I employ contact theory and critical policy analysis. I find that as students grow up in divided schools and communities, their conceptions of the self and of people from other ethnic groups are constituted by these experiences of segregation. While the nation’s education policies currently include more initiatives for integrated education, these have yet to be implemented satisfactorily, meaning that public schools could teach inclusion and serve as a mechanism for dispelling negative stereotypes, but to do so requires a reconceptualization of ethnic difference and a cohesive vision of national identity.

This article talks about the formation of communities and its implications. Little Tokyo is pointed out as an example of a community borne out as a result of a segregationist US society. During World War II there was a dramatic decline in the construction of Little Tokyo since Japanese people were put into interment camps. There is a dramatic shift of the function of Little Tokyo before the war and after the war. Post-WW II demonstrates“ paradox dispersal” because as the ethnic population was no longer heavily concentrated in one area the historic Little Tokyo communities assumed a new importance as they are regarded as a symbol ethnic identity and community. The power struggle in the community is part of a broader political, economic, and cultural issue. Three forces are responsible for shaping the history of community development in Little Tokyo: Japanese corporations, the region’s elite development regimes, and local Japanese American organizations. Post WW II “urban renewal” opened the door to Japanese corporate capital. This policy is discussed insofar as it influences the community. By late 1980s Japanese Americans were able to shape the Little Tokyo development as they gain more economic power. The ‘recreation center’ controversy is discussed.

Scholarly debates over the nature of political parties and the identity of their principal actors have been hampered by relative inattention to the historical processes of internal party change. This study, drawing on archival sources, interviews, and one of the co-author’s personal experiences, analyzes the Georgia delegate challenge to the 1968 Democratic Convention as a case of internal party conflict generating lasting institutional reform, with implications for existing theories of party development, nominating politics, and democratic representation. In a convention marked by an unusually large number of challenges to state party delegations, the Georgia delegate challenge was unique. There, a conflict between the segregationist regulars and the moderate and liberal Democrats was complicated by an internal division in the latter camp between Hubert Humphrey and Eugene McCarthy supporters. The McCarthy forces’ success in garnering a dominant position within the challenge delegation alienated many of the Georgia movement’s organizers and leaders. The McCarthy campaign's takeover also linked this southern challenge both to the antiwar politics coloring the national nomination fight and to a particular conception of representation that would influence subsequent party reform efforts. In tracing the origins, dynamics, and aftermath of Georgia’s delegate challenge, we show both that group- and candidate-driven efforts together shape party development over time, and that normative ideas concerning representation can play causal roles in party development.

In 1918, Batho was founded as one of South Africa’s first so-called “model locations”. In addition to sound town planning and layout, brick houses, and public amenities, Batho also became known for its “generous” plots or “garden areas of 50 ft. by 75 ft.” and the ornamental front gardens that were laid out on them. The Bloemfontein municipality’s decision to provide residents with “garden areas” was motivated by a number of reasons, most of which were of a political nature and embedded in the segregationist ideology of the time. This article discusses the “garden areas” and the gardens that were laid out on them by Batho’s gardeners. Furthermore, the article investigates the city council’s efforts to turn the “model location” into a “garden location” and the Batho gardeners’ own efforts to this effect during the period 1918–1939. The gardeners’ front gardens resembled the English-style gardens that were popular among Bloemfontein’s whites during the 1920s and 1930s. Information obtained through archival research, field work, and oral history interviews point to the gardeners’ preference for a simple formal axial garden layout enclosed by clipped hedges and often adorned with topiary. A fondness of topiary encouraged Batho’s gardeners to create hedges, edges, and a variety of other topiary styles which had gradually evolved into a style of topiary that may be described as “township topiary”. Over time “township topiary” became a tangible expression of a unique garden identity among Batho’s gardeners. Due to the processes of acculturation and intercultural influence, which involved the Dutch, British, and African cultures, Batho’s historical and present gardens are described as semi-vernacular or “hybrid”. Most gardens display an unmistakable English cottage-garden style but a distinctly African accent is also visible.

For tuber-bearing Solanum species, six monogenic recessive synaptic mutants, designated sy-1, sy-2, sy-3, sy-4, ds, and dsc have been reported in the literature. In the present investigation no indication for the existence of the mutant sy-1, affecting megasporogenesis only, was found. The mutant ds was confirmed to display typical desynaptic behaviour in microsporogenesis and shown to similarly affect megasporogenesis. It furthermore proved to be allelic to the mutants sy-3 and dsc. It is proposed that the mutants sy-3, ds, and dsc be uniformly designated ds-1, whereas the remaining mutants sy-2 and sy-4 (possibly identical) may be designated simply as synaptic mutant until their actual identity has been established. The observed F1 segregations generally support monogenic recessive inheritance of ds-1. However, in one cross progeny the expected mutant phenotype was not clearly expressed in contrast with its reciprocal, which might indicate cross-specific influence of the cytoplasm on ds-1 expression. The potential value and limitations of desynaptic (ds-1ds-1) mutants for potato breeding and true potato seed production are discussed.Key words: Solanum, (de)synaptic mutants, microsporogenesis, megasporogenesis, 2n gametes.

The paper describes a methodology of applying X-ray computed tomography (CT) in studying textural–morphological characteristics of sulfide-bearing ultramafic rocks from the Yoko-Dovyren layered massif in the northern Baikal area, Buryatia, Russia. The dunites are used to illustrate the applicability of a reliable technique for distinguishing between grains of sulfides and spinel. The technique enables obtaining statistical characteristics of the 3D distribution and size of the mineral phases. The method of 3D reconstructions is demonstrated to be applicable at very low concentrations of sulfides: no than 0.1–0.2 vol %. Differences between 3D models are determined for sulfide segregations of different size, in some instances with features of their orientation suggesting the direction of percolation and accumulation of the sulfide liquids. These data are consistent with the morphology of the largest sulfide segregations, whose concave parts adjoin the surface of the cumulus olivine and simultaneously grow into grains of the poikilitic plagioclase. Detailed information of these features is useful to identify fingerprints of infiltration and concentration of protosulfide liquids in highly crystallized cumulate systems.

Dalit women in India suffer multilayered form of marginalization. They are discriminated not only based on their gender, but also because of their caste identity. This impacts their literacy, life expectancy, among other human indicators. Despite the emphasis on the intersectionality between caste and gender by Dr. BR Ambedkar and later by other social reformers like Dr. Ram Manohar Lohia, the mainstream movements have failed to provide a separate discourse on safeguarding the rights of Dalit women. The question of caste-based discrimination has by and large focused on the identity of a Dalit, irrespective of the gender, and the injustices inflicted on the social group as a whole. The upper caste led feminist discourse has been equally ignorant of the multiple oppressions faced by Dalit women. This paper deals with the critique of the Dalit movement as well as the feminist movement, and attempts to envision a broader global social justice by reading the ideas of Ambedkar and Lohia together.

Four races of bean rust were identified from Oahu and Maui by testing on nineteen differential cultivars. All Hawaiian bean cultivars were very susceptible to the four races. F2 segregations of crosses between the differential cultivars and the local cultivars have identified one or more dominant genes for resistance to one, 2, 3 or 4 rust races as well as other genes which do not give qualitative ratios. F3 families are being evaluated to further identify the inheritance of these genes.

The “highway to nowhere” is a 1.32 mile fragment of an arterial expressway located in Baltimore, Maryland. This segment was designed to contribute to a proposed limited access highway system that was never constructed after years of activism, debate, and lawsuits. This article examines the history of the construction of this highway segment to suggest that conflicts over the design, sitting, and construction of infrastructure are fundamentally struggles over the definition and production of space. This analysis utilizes Henri Lefebvre’s triad of spatial production as an analytical framework to identify distinct spatial forms that surface during the process of infrastructure building. Utilizing this analytical framework may enrich the STS-based infrastructure inquiries by bringing to the surface the multiple forms of spatial production that structure system-building activities. In conclusion, I suggest that utilizing Lefebvre’s triad within studies of infrastructure surfaces important, and potentially transformative, local claims to space. Such claims are of renewed importance as cities across the US confront the segregationist histories of the built environment.

The COVID-19 pandemic exposed and accelerated many gendered labour market inequalities in Australia and around the world. In this introduction to our special issue, ‘Workplace Gender Equality: Where are we now and where to next?’, we examine the impact of the pandemic on women’s employment, labour force participation, earnings, unpaid care work and experience of gendered violence. We identify five key areas where action is urgently required to create a more equitable post-pandemic recovery: addressing gender-based labour market segregations and discrimination; building access to mutually beneficial flexibility; ensuring a more gender-equitable distribution of unpaid care; confronting gender-based violence at work and beyond; and mobilising union action through gender equality bargaining.

This article builds a framework for a relational approach to segregation that emphasizes structures of interactions, transactions, and ties between and within social categories. Rather than explaining segregation with dominants imposing formal rules or homophilic people sorting themselves, I highlight segregation’s emergence amid dueling control efforts among actors with malleable categorical identities. And rather than assuming segregation necessarily fuels cycles of inequality or persecution, I identify nuanced advantages and disadvantages for different actors in social conflict. I also explore an underappreciated role of institutions in segregation: They guide relations across different domains of activity that may have different degrees of segregation. An overarching theme is that segregation is not a specific thing with regular causes and effects but an inherently contradictory structural feature of relations that evolves as actors struggle for control.

Rice (Oryza sativa L.) is the primary food for half of the global population. Recently, there has been increasing concern in the rice industry regarding the eating and milling quality of rice. This study was conducted to identify genetic information for grain characteristics using a recombinant inbred line (RIL) population from a japonica/indica cross based on high-throughput SNP markers and to provide a strategy for improving rice quality. The RIL population used was derived from a cross of “Kaybonnet (KBNT lpa)” and “ZHE733” named the K/Z RIL population, consisting of 198 lines. A total of 4133 SNP markers were used to identify quantitative trait loci (QTLs) with higher resolution and to identify more accurate candidate genes. The characteristics measured included grain length (GL), grain width (GW), grain length to width ratio (RGLW), hundred grain weight (HGW), and percent chalkiness (PC). QTL analysis was performed using QTL IciMapping software. Continuous distributions and transgressive segregations of all the traits were observed, suggesting that the traits were quantitatively inherited. A total of twenty-eight QTLs and ninety-two candidate genes related to rice grain characteristics were identified. This genetic information is important to develop rice varieties of high quality.

Abstract The local government of Jakarta has limited capacity to meet the needs for residential. Therefore, A private developer has the opportunity to help the local government respond by building a large-scale planned residential named Bintaro Jaya. It is developed in the South Jakarta Area and the South Tangerang Region. The development caused a gated community and led to physical and social segregation with the previous local community. This research is aimed to identify the spatial segregation in Bintaro Jaya. These hypotheses are analyzed by using a socio-spatial approach and descriptive analysis. The method is interpreted from Google Earth Imagery map Landsat 8 OLI/TIRS based on the masterplan of Bintaro Jaya to identify delineation settlement status and field observation as an image interpretation data validation. This paper describes the phenomenon of spatial segregation that potentially can be exclusive space. The form of segregation is identified by walls, roads, and economic centers. In which the economic center can be a transitional space that functions as a communal space between segregations.

Garlic (Allium sativum) is cultivated worldwide and appreciated for its culinary uses. In spite of primarily being asexually propagated, garlic shows great morphological variation and adaptability to diverse production environments. Molecular markers and phenotypic characteristics have been used to assess the genetic diversity among garlics. In this study, we undertook transcriptome sequencing from a single garlic plant to identify molecular markers in expressed regions of the garlic genome. Garlic sequences were assembled and selected if they were similar to monomorphic sequences from a doubled haploid (DH) of onion (Allium cepa). Single nucleotide polymorphisms (SNPs) and insertion–deletion (indel) events were identified in 4355 independent garlic assemblies. A sample of the indels was verified using the original complementary DNA (cDNA) library and genomics DNAs from diverse garlics, and segregations confirmed by sexual progenies of garlic. These molecular markers from the garlic transcriptome should be useful for estimates of genetic diversity, identification and removal of duplicate accessions from germplasm collections, and the development of a detailed genetic map of this important vegetable crop.

Cytoplasmic-genic male sterility (CMS) is used to produce hybrid onion seed. For the most widely used source of CMS in onion, male sterility is conditioned by the interaction of sterile (S) cytoplasm and the homozygous recessive genotype at a single nuclear male-fertility restoration locus (Ms). Maintainer lines used to seed-propagate male-sterile lines possess normal fertile (N) cytoplasm and the homozyous recessive genotype at the Ms locus. Presently, it takes 4 to 8 years to establish if maintainer lines can be extracted from an uncharacterized population or family. We previously developed a PCR marker useful to distinguish N and S cytoplasms of onion. To tag the nuclear male-fertility restoration locus (Ms), we evaluated segregation at Ms over at least three environments. Segregations of AFLPs, RAPDs, and RFLPs revealed molecular markers flanking the Ms locus. We are working to convert these linked molecular markers to nonradioactive PCR-based detection. The organellar and nuclear markers were used to select plants from open-pollinated onion populations and determine if the number of test-crosses required to identify maintaining genotypes.

This article presents a comprehensive review of the transnational perspective in the study of communism and the implications of this methodological turn for the transformation of the field itself. While advancing new topics and interpretative standpoints with a view to expanding the scope of such an initiative in current scholarship, the author argues that the transnational approach is important on several levels. First, it helps to de-localize and de-parochialize national historiographies. Second, it can provide the background to for the Europeanization of the history of the communist period in former Eastern Europe and the Soviet Union. Third, and most importantly, the transnational approach can reconstruct the international dimension of the communist experience, with its multiple geographies, spaces of entanglement and transfer, and clustered, cross-cultural identity-building processes. The article concludes that the advent of transnationalism in the study of communism allows for the discovery of various forms of historical contiguousness either among state socialisms or beyond the Iron Curtain. In other words, researchers might have a tool to not only know more about less, but also to resituate that “less” in the continuum of the history of communism and in the context of modernity. The transnational approach can generate a fundamental shift in our vantage point on the communist phenomenon in the twentieth century. It can reveal that a world long perceived as mostly turned inward was in fact imbricate in wider contexts of action and imagination and not particularly limited by the ideological segregationism of the Cold War.

Abstract Objectives A well-documented paradox is that Hispanics tend to live longer than non-Hispanic Whites (NHW), despite structural disadvantages. We evaluate whether the “Hispanic paradox” extends to more comprehensive longitudinal aging classifications and examine how lifecourse factors relate to these groupings. Methods We used biennial data (1998–2014) on adults aged 65 years and older at baseline from the Health and Retirement Study. We use joint latent class discrete time and growth curve modeling to identify trajectories of aging, and multinomial logit models to determine whether U.S.-born (USB-H) and Foreign-born (FB-H) Hispanics experience healthier styles of aging than non-Hispanic Whites (NHW), and test how lifecycle factors influence this relationship. Results We identify four trajectory classes including, “cognitive unhealthy,” “high morbidity,” “nonaccelerated”, and “healthy.” Compared to NHWs, both USB-H and FB-H have higher relative risk ratios (RRR) of “cognitive unhealthy” and “high morbidity” classifications, relative to “nonaccelerated.” These patterns persist upon controlling for lifecourse factors. Both Hispanic groups, however, also have higher RRRs for “healthy” classification (vs “nonaccelerated”) upon adjusting for adult achievements and health behaviors. Discussion Controlling for lifefcourse factors USB-H and FB-H have equal or higher likelihood for “high morbidity” and “cognitive unhealthy” classifications, respectively, relative to NHWs. Yet, both groups are equally likely of being in the “healthy” group compared to NHWs. These segregations into healthy and unhealthy groups require more research and could contribute to explaining the paradoxical patterns produced when population heterogeneity is not taken into account.

The subdivision of the Drosophila wing imaginal disc into dorsoventral (DV) compartments and limb-body wall (wing-notum) primordia depends on Epidermal Growth Factor Receptor (EGFR) signaling, which heritably activates apterous (ap) in D compartment cells and maintains Iroquois Complex (Iro-C) gene expression in prospective notum cells. We examine the source, identity and mode of action of the EGFR ligand(s) that specify these subdivisions. Of the three known ligands for the Drosophila EGFR, only Vein (Vn), but not Spitz or Gurken, is required for wing disc development. We show that Vn activity is required specifically in the dorsoproximal region of the wing disc for ap and Iro-C gene expression. However, ectopic expression of Vn in other locations does not reorganize ap or Iro-C gene expression. Hence, Vn appears to play a permissive rather than an instructive role in organizing the DV and wing-notum segregations, implying the existance of other localized factors that control where Vn-EGFR signaling is effective. After ap is heritably activated, the level of EGFR activity declines in D compartment cells as they proliferate and move ventrally, away from the source of the instructive ligand. We present evidence that this reduction is necessary for D and V compartment cells to interact along the compartment boundary to induce signals, like Wingless (Wg), which organize the subsequent growth and differentiation of the wing primordium.

Mango (Mangifera indica L.) belongs to the genus Mangifera and family Anacardiaceae, and is an important tropical fruits. Artificial cross breeding (hand pollination) is an important method for breeding new mango cultivars. It is easy to produce false hybrids in the process of artificial pollination breeding. Therefore, it is necessary to establish rapid and accurate molecular detection methods to identify the authenticity of hybrids. Mango ‘Jinhuang’ and ‘Renong No.1′ and 65 individual plants of their F1 hybrids were used as experimental materials, eight SSRs (simple sequence repeats) primer pairs with polymorphism in parents were used to identify the F1 hybrids by capillary electrophoresis. The results showed that PCR product size (bp) for eight primers ranged from 108 bp (ES55) to 176 bp (ES63) in 65 samples. A total of 62 true hybrids were identified from 65 hybrid progenies, and the true hybrid rate was 95.38%. A total of 18 alleles were amplified by eight SSRs, seven SSR loci showed binary segregations, whereas only one SSR locus ES83 showing ab:ac:bb:bc segregation fitted to the expected segregation ratio of 1:1:1:1. The value of expected heterozygosity (He), ranged from 0.34 to 0.62, whereas the value of observed heterozygosity ranged from 0.44 to 0.81. Chi-square test showed that eight SSR loci were in accordance with Mendel’s segregation law. The results of cluster analysis showed that the parents and 62 true hybrids could be classified into two categories at 0.58: the first category contained 27 offspring, clustered with ‘Jinhuang’ and showed a maternal genetic tendency. The second category contained 35 offspring, clustered with ‘Renong No.1′ and showed a partial paternal genetic tendency. DNA fingerprint of hybrids from ‘Jinhuang’ × ‘Renong No.1′ cross were constructed using eight SSR primers for variety protection.

Two single-tree linkage maps were constructed for Eucalyptus urophylla and Eucalyptus grandis, based on the segregation of 480 random amplified polymorphic DNA (RAPD) markers in a F1 interspecific progeny. A mixture of three types of single-locus segregations were observed: 244 1:1 female, 211 1:1 male, and 25 markers common to both, segregating 3:1. Markers segregating in the 1:1 ratio (testcross loci) were used to establish separate maternal and paternal maps, while markers segregating in the 3:1 ratio were used to identify homology between linkage groups of the two species maps. An average of 2.8 polymorphic loci were mapped for each arbitrary decamer primer used in the polymerase chain reaction. The mean interval size beween framework markers on the maps was 14 cM. The maps comprised 269 markers covering 1331 cM and 236 markers covering 1415 cM, in 11 linkage groups, for E. urophylla (2n = 2x = 22) and E. grandis (2n = 2x = 22), respectively. A comparative mapping analysis with two other E. urophylla and E. grandis linkage maps showed that RAPDs could be reliable markers for establishing a consensus species map. RAPD markers were automatically and quantitatively scored with an imaging analyzer. They were classified into four categories based on their optical density. A fragment intensity threshold is proposed to optimize the selection of reliable RAPD markers for future mapping experiments. Key words : genetic linkage map, Eucalyptus urophylla, Eucalyptus grandis, random amplified polymorphic DNA, RAPD, automated data collection.

Brain synchronizations are orchestrated from neuronal oscillations through frequency interactions, such as the alpha rhythm during relaxation. Nevertheless, how the intrinsic interaction forges functional integrity across brain segregations remains elusive, thereby motivating recent studies to localize frequency interactions of resting-state fMRI (rs-fMRI). To this point, we aim to unveil the fMRI-based spectral interactions using the time-frequency (TF) analysis; however, Fourier-based TF analyses impose restrictions on revealing frequency interactions given the limited time points in fMRI signals. Instead of using the Fourier-based wavelet analysis to identify the fMRI frequency of interests, we employed the Hilbert–Huang transform (HHT) for probing the specific frequency contribution to the functional integration, called ensemble spectral interaction (ESI). By simulating data with time-variant frequency changes, we demonstrated the Hilbert TF maps with high spectro-temporal resolution and full accessibility in comparison with the wavelet TF maps. By detecting amplitude-to-amplitude frequency couplings (AAC) across brain regions, we elucidated the ESI disparity between the eye-closed (EC) and eye-open (EO) conditions in rs-fMRI. In the visual network, the strength of the spectral interaction within 0.03–0.04 Hz was amplified in EC compared with that in EO condition, whereas a canonical connectivity analysis did not present differences between conditions. Collectively, leveraging from the instantaneous frequency of HHT, we firstly addressed the ESI technique to map the fMRI-based functional connectivity in a brand-new AAC perspective. The ESI possesses potential in elucidating the functional connectivity at specific frequency bins, thereby providing additional diagnostic merits for future clinical neuroscience.

Genetics of resistance in chickpea accession WR-315 to Fusarium wilt was investigated, and a concise set of differentials was developed to identify races of Fusarium oxysporum f. sp. ciceris. A population of 100 F7 recombinant inbred lines (RILs) from a cross of WR-315 (resistant) and C-104 (susceptible) was used to study genetics of resistance to races 1A, 2, 3, 4, and 5 of F. oxysporum f. sp. ciceris, and a population of 26 F2 plants from a cross between the same two parents was used to study inheritance of resistance to race 2. Segregations of the RILs for resistance to each of the five races suggest that single genes in WR-315 govern resistance to each of the five races. A 1:3 resistant to susceptible ratio in the F2 population indicated that resistance in WR-315 to race 2 was governed by a single recessive gene. A race-specific slow disease progress reaction was observed in chickpea line FLIP84-92C(3) to infection by race 2, a phenomenon termed as slow wilting, that is different from previously reported late wilting with respect to latent period, disease progress rate, and final disease rating. Twenty-nine germ plasm lines (27 Cicer arietinum and two C. reticulatum) including previously used differentials were evaluated for their reactions to infection by the five races. Only eight of the 29 germ plasm lines differentiated at least one of the five races based on either resistant or susceptible reactions, whereas the remaining germ plasm lines were either susceptible or resistant to all five races or differentiated them by intermediate reactions. A concise set of eight chickpea lines comprised of four genotypes and four F7 RILs with vertical resistance was developed as differentials for race identification in F. oxysporum f. sp. ciceris. These differential lines were characterized by early appearance of wilt symptoms, and clear and consistent disease phenotypes based on no wilt or 100% wilt incidence, which offers important improvements over previously available differential sets and provides more precise and unambiguous identification of the races.

Introduction. Due to the process reasons, the structure of cast parts of the railway rolling stock (RRS) often has embedded flaws that affect drastically their strength. The degree of impact depends on many factors including the shape and location of defects in the product. The shape of the defect has the greatest effect under alternating loads. This often refers to dynamically loaded parts of the RRS underframe. The defect oriented perpendicularly to the direction of tensile loads reduces the component life to the maximum. To identify embedded flaws, the parts are subjected to ultrasonic testing by the classical pulse-echo technique. However, such methods require increased validity and informativity. For example, they do not provide the determination of the type and orientation of the defect. Materials and Methods. Features, advantages and disadvantages of the classical pulse-echo technique of the ultrasonic non-destructive testing, which is based on the registration of the following echo signals, are considered: sent; reflected from the opposite surface (bottom) of the object; reflected from the defect (if any). The pulse arrival time is proportional to the thickness of the part. If there is a defect, this time is proportional to the distance from the pulse input surface to the defect. This method can determine the presence of a defect, but it cannot determine its type. Research Results. To determine the shape of a defect, a dualfrequency defectometry method is proposed. Its principle, algorithm and implemented analytical dependencies are described. When an echo signal from a defect is detected in the monitoring object, the amplitudes of the bottom signals and the amplitudes of the echo signals from the defect are measured at the ultrasonic wave frequencies of 2.5 MHz and 5.0 MHz. The defect shape factor is calculated from the analytical dependence; and the type of defect is determined. It can be volume (pores, shells, non-metallic inclusions) or planar (cracks, segregations, etc.). Discussion and Conclusions. A dual-frequency defectometry method to determine the type of defect under the manual ultrasonic testing of the RRS cast parts is proposed in the paper. For an express automated use of the proposed method, the software product NDTRT-07.04-L is developed, and its operation algorithm is described. The application of the technique can increase the validity and informativity of the test results

Abstract The study included twenty genotypes of triticale, whose seeds were sown during 2018-2019 season at the Research Station of the Faculty of Agriculture, University of Kirkuk in the Sayyadah region on three dates (5 November, 20 November and 5 December) using randomized complete block design according to split plot system with three replications. The data were recorded for traits: first, second and third developmental stages, number of days to 50% flowering, plant height, flag leaf area, number of tillers per plant, number of spikes per plant, length and weight of spike, number of spikelet’s per spike, number of grains per spike, 1000 grains weight, biological yield, grain yield per plant, harvest index, protein percent, specific weight, gluten percent, flour strength, moisture percent and ash percentage, The data were analyzed to identify the nature of the differences between genotypes and planting dates. Because of the significant (genotypes x planting dates) interaction, a cluster analysis was conducted with the aim of grouping similar genotypes into homogeneous groups and estimating the degree of genetic diversity between them through the use of hierarchical clustering technology to estimate distances between groups of genotypes formed for each planting date separately. The results showed that the mean squares of genotypes' was highly significant 1% for all traits except harvest index, with a highly significant interaction with dates for all traits except number of spikelet’s and protein percent. The stages of the cluster analysis showed that the genotypes were distributed into 13 groups for the first date and 14 groups for the second and third dates. Some groups included one genotype, indicating the difference of these genotypes from other due to the difference in their genetic origin, which was consequently reflected on their performance, while other groups includes two genotypes. It is concluded from the results of the clustering analysis that there is a strong convergence between the genotypes of stage 18 with the genotype LIRON at the first date and with POLLMER in the second and third dates because they have the lowest euclidean distances, and this requires avoiding crosses between these pairs, while the highest distance was between CMH80 and CMH82 in the first and third dates and CENT/1715 and POPP-CAAL in the second date indicated high genetic variation between them and other genotypes, which may be due to the variation in their genetic origin or to having preferred main genes, other genotypes devoid of them, which encourages their introduction into hybridization with genotypes that showed distinct genetic variation to take advantage of the phenomenon of heterosis and its segregations.

Abstract Introduction: Apart from the mutations in the kinase domain of BCR-ABL, other important mechanisms of resistance to the first line imatinib (IM) therapy in chronic myeloid leukemia (CML) are pharmacokinetics factors, especially an intracellular concentration of IM. ATP Binding Cassette (ABC, ensuring efflux) and Solute Carrier (SLC, ensuring uptake) super families are responsible for transportation several drugs including IM. Gene expression and activity of the SLC and ABC transporters may be affected by polymorphisms in their promoter regions and may notably contribute to the treatment failure. Objectives: The aim of this study was to identify polymorphisms in the promoter regions of the selected SLC and ABC transporter encoding genes and evaluate their association with the response to the first line IM therapy in CML patients in chronic phase. Material and Methods: The patient cohort consists of 40 CML patients with optimal response and 40 resistant patients (without mutations in the BCR-ABL kinase domain) to the IM in the first line with 24 months follow-up from the therapy initiation. All 80 CML patients were taking a standard dose of IM and in none of them were evidence of non-compliance. The promoter regions (~1000bp) of selected ABC (n=4) and SLC (n=15) genes with the annotated function of drug transportation were amplified. The next generation sequencing was applied for ultra-wide sequencing of altogether 1419 amplicons (454 GS Junior, Roche AppliedScience; MiSeq Series, Illumina). The obtained sequences were analyzed and evaluated with the focus on the presence of single nucleotide polymorphisms (SNPs) using NextGENe software (Softgenetics). The Fisher´s exact binomial test of goodness of fit was used to evaluate haplotype frequency distribution among patient cohort. The expression analysis of a selected gene was analyzed using RT-qPCR (TaqMan® Assays) in total leukocytes of peripheral blood with GUS as a housekeeping gene. Results: Among 1419 evaluated sequences we identified 96 SNPs (2-12 SNPs per one promoter) of which nine was not yet annotated. We identified 2 SNPs, rs460089 (C/G) and rs460271 (C/G), with uniform alleles co-segregations in the promoter of the gene SLC22A4 when GG haplotypes were significantly more frequent in resistant patients (P<.05). Of all resistant patients, 69% carried GG haplotypes, 17% CG and 14% CC. The frequency of haplotypes among responding patients was 31% of GG, 53% CG and 16% CC. As SLC22A4 is imatinib transporter (He L et al. Hum Genomics 2009), we measured the level of the gene expression associated with both co-segregated SNPs. Among all patients analyzed regardless of the response to IM, the GG haplotypes showed a significantly lower expression of SLC22A4 in comparison to CG and CC haplotypes (P<.05). Even greater significant differences in the expression were found when comparing GG haplotypes within patients resistant to IM in comparison to CG haplotypes within patients with optimal response (P<.01). Conclusion: In this work, we found a significantly decreased gene expression of SLC22A4 in total leukocytes of peripheral blood that was associated with GG haplotypes of 2 SNPs in the SLC22A4 promoter, where GG haplotypes were significantly more frequent in CML patients resistant to the first line imatinib treatment in comparison to the patients with an optimal response. We assume that GG haplotypes have altered activity of SLC22A4 promoter resulting in the reduced hOCTN1 expression and thus in lower intracellular IM concentration that may be insufficient for optimal response. The experiments on the SLC22A4 promoter activity alterations associated with GG haplotypes are ongoing. We believe that screening for rs460089 (C/G) and rs460271 (C/G) SNPs among patients with newly diagnosed CML could be an important prognostic genetic factor helping to select a tyrosine kinase inhibitor that is not dependent on the active transportation through the cell membrane.

The 90s ushered in the era of molecular genetics in Pakistan. Our centuries’ old tradition of consanguineous marriages, resulting in the availability of large, inbred families with inherited disorders, proved to be a goldmine for geneticists, working to discover new genes and their functions. A multitude of novel genes with previously unknown functions were discovered through genetic linkage analysis, a technique that compares the segregations of DNA markers in normal and affected family members to pinpoint the region that contains the suspect gene. The first few landmark publications on linkage analysis in genetic diseases, from Pakistan, identified only the regions harboring the suspected disease genes.1,2 As the field advanced, disease causing mutations segregating in affected family members were identified through Sanger DNA sequencing of candidate genes in the linked region. In the last decade, the advent of high throughput techniques such as whole exome analysis and animal disease modeling, functional genomics studies became an integral of part of such genetic studies. In addition, bioinformatics tools were developed for predictive modeling of the effect of mutations on protein structure. The analysis of a single large multigenerational family with a genetic disorder could provide the same information that would be obtained from many small nuclear families, as usually found in developed countries. This allowed Pakistani researchers to attract collaborators from Universities around the world. DNA samples of numerous Pakistani families were sent to labs across the world for analysis, many times accompanied by a PhD student who would typically spend around six months working on those families. Universities developed efficient pipelines, whereby students would find families with genetic diseases, extract DNA and carry out linkage analysis and, in some cases, identify the gene mutations using Sanger sequencing. This led to a significant increase in the number of publications on genetics, from Pakistan. However, despite all the good work carried in the country, no credible effort had been made to build national capacity to carry the work beyond initial mutation screening. We lack the ability to conduct good quality high through put –omics analysis and animal model studies within the country. There are several reasons for this. Firstly, the cost of such research is prohibitive. While some institutes have invested in next generation sequencing platforms, these machines are largely underutilized due to high cost of consumables. Lack of adequate funding for reagents, required for genomic, transcriptomic and proteomic studies, is a major roadblock. Secondly, the ease in attracting foreign collaborators to carry out the functional studies in their labs, has made many Pakistani researchers complacent, often, they are happy to be co-authors in research papers without having to go through the pains to set up the required laboratory facilities. Lastly, the bureaucratic processes and red tape, especially in public sector Universities, make procurement of chemicals and consumables, tedious and time consuming, resulting in demotivation of researchers and faculty. There is a need to address these issues, if we wish to move towards self-sufficiency in conducting high level functional genomics and stem the flow of biological samples from Pakistan. While genetic studies in Pakistan have resulted in the discovery of many novel genes, the benefit of these studies is yet to trickle down to the patients. The willingness of the affected families to participate in these studies is crucial. Many affected families belong to far flung rural areas and have no understanding of their disease, how it is inherited or the implications of participating in such research. It is unlikely that families participating in these studies have any immediate benefits and they should be informed at the time of recruitment using common language which they are able to understand. The role of Institutional Ethics and Review Boards, for the protection of study participants and their rights, needs to be strengthened. It is important not to abandon these families after sample collection but to relay the results of the study and counsel them regarding their future options. Despite the rapid advances in genetic medical knowledge, our population has yet to reap its benefits. A small step in right direction is the Compulsory Blood Test of the Relatives of Thalassemia Patient Bill-2017, which makes it compulsory for couples to get tested before marrying. However, the scarcity of gene testing facilities and healthcare professionals trained in clinical genetics is an impediment to the implementation of this bill in the true spirit. It is becoming imperative to educate our healthcare professionals regarding the application of genetics to medical practice. Clinical genetics and its related competencies need to be recognized as medical specialties in the country, before they can be introduced into mainstream clinical practice to improve health outcomes of our affected families.

Abstract This paper examines the context-dependent role of race as a predictor of non-electoral political participation. Prior country-level studies have documented group-level differences in a variety of forms of participation in South Africa and the United States, but have found few to no differences in Brazil. Why are members of one group more engaged in certain political activities than members of other groups only in specific contexts? Why do members of socioeconomically deprived groups, such as non-Whites, participate more than better-off groups in acts that require group mobilization in South Africa and the United States but not in Brazil? Results from the World Values Survey and the International Social Survey Programme show that Blacks and Coloureds in South Africa and Blacks in the United States participate more than Whites in activities that demand prior organization and mobilization, whereas group differences are negligible in Brazil. I argue that (1) race as a driver of political mobilization is conditional on the existence of politicized racial identities; (2) members of groups that share a strong collective identity participate in direct political action more than predicted by their socioeconomic background; (3) politicization of identities is the product of racial projects that deploy the state apparatus to enforce group boundaries for the implementation of segregationist policies as well as the reactions against them; and (4) by enforcing group boundaries, those systems unintentionally create the conditions for the formation of politicized group identities. In the absence of such requisites, political mobilization along racial lines would be weak or nonexistent.

AbstractHukou registration is an instrument to control nonplanned population and capital movements, which the Chinese Communist Party has been exploiting extensively since the 1950s. It requires that each Chinese citizen be classified as either an agricultural or nonagricultural hukou inheritor and be distinguished by their location with respect to an administrative unit. Hukou distribution used to be entirely determined by birth, but nowadays, Chinese citizens can self-select their hukou status based on their ability that causes selection bias in conventional wage decomposition by hukou types. To avoid this bias, I estimated hukou-based earning discrimination by matching Chinese individuals based on a rich set of individual-, family-, and society-level characteristics. By deploying a recent nationally representative dataset, this paper finds that significant earning discriminations exist against agricultural hukou people. I further investigated the impact of hukou adoption within work ownership, work and employer types, and labor contract conditions. I argue that earning difference by hukou is not due to rural–urban segregations; rather, it is systematic and institutionally enforced. This is because, contrary to self-employment and no labor contract conditions, discrimination exists only when others employ them and where a labor contract condition is enforced. Moreover, they face discrimination only when they work for the Chinese government, not when they work for private firms, and they face higher discrimination in nonagriculture-related professions compared to agriculture-related professions.

This graduating paper analyzes Jim Crow laws as reflected in Langston Hughes’ short stories “Breakfast in Virginia” and “Trouble with the Angels”. This study aims to identify the practice of Jim Crow laws as seen in “Breakfast in Virginia” and “Trouble with the Angels”. This graduating paper applies mimetic theory proposed by Abrams since it is the most suitable approach to be used to analyze the connection between the literary work and the reality. There are two types of data which are used in this paper. The primary data are the short stories entitled, “Breakfast in Virginia” and “Trouble with the Angels”. Meanwhile, the secondary data are the references that support the analysis and are taken from the internet browsing.Based on the data analysis, this research concludes that segregation is the practice of Jim Crow laws in these two short stories. The segregations are clearly seen mostly in public places. In “Breakfast in Virginia” the segregations happen in the train, specifically in Jim Crow car and in the dining car in Virginia. Meanwhile, in “Trouble with the Angels” the segregations are clearly visible in the hotel and in the theater in Washington. In “Breakfast in Virginia” the segregations are faced by African American soldiers during World War II. Meanwhile, in “Trouble with the Angels” the segregations are experienced by African American actors and the other African American citizens of Washington. These two short stories show that Jim Crow laws made African Americans life getting worse, especially in public places. Both in “Breakfast in Virginia” and in “Trouble with the Angels”, African Americans cannot use the same public facilities as the whites. They can only use public facilities specially provided for the African Americans which have improper conditions. During the practice of Jim Crow laws, their rights are denied. This is proved by the segregations that do not only restrict African Americans from middle or low class status but also restrict those who have a higher status regardless their influential contribution toAmerica. This condition is painful for them.

O presente ensaio propõe uma reflexão sobre a dificuldade de acesso aos mecanismos de justiça e precariedade de defesa das camadas populares no Brasil frente a uma postura autoritária por parte das esferas de decisão personificadas pelo Poder Judiciário. Temos uma constituição democrática que garante direitos difusos, e coletivos, mas que na prática, quando falamos de direitos inerentes aos mecanismos processuais do uso do contraditório e da ampla defesa por exemplo, vimos que na prática são direitos que não se concretizam plenamente para ricos e pobres. A proposta do presente texto é mostrar que quanto maior é o grau de exclusão de um indivíduo, maior é seu distanciamento das garantias legais e constitucionais quando nos referimos aos mecanismos de defesa dentro do ordenamento jurídico formal, já que em regra é atendido por uma defensoria pública sobrecarregada, com poucos recursos e muitas vezes precárias condições para realizar uma defesa plena e irrestrita, como diz a norma. Ainda abordamos a herança autoritária dos períodos de ditadura e seus reflexos em práticas processuais retificando um procedimento violador de direitos e uma lei altamente seletiva e segregatória. Por fim nosso trabalho é fruto de pesquisa qualitativa e bibliográfica sendo concluído com um olhar voltado para a necessidade urgente de mudanças na formação dos profissionais do direito, humanizando-os. Quando assim acontecer teremos um sistema de justiça criminal que busque de fato justiça com equidade garantindo a todos os cidadãos brasileiros igualdade de armas na busca por uma decisão justa. Cidadania. Autoritarismo. Sistema de justiça.

We have a democratic constitution that insures diffuses rights, and collective, nevertheless in the practice, when we talk about rights inherent to the procedural apparatus' use of contradictory and the ample defense for example, we perceive that in the practice they are immaterialized rights to the rich and poor. The purpose of this text is to show that how bigger is the exclusion rate of an individual, the bigger will be the distance of the legal and constitutional insurances when we refers to the defense mechanisms within the formal legal order, since as a rule it's attended by an overwhelmed public defense with few resources and, oftentimes, precarious conditions to perform a full and unrestricted defense, as it says in the regulation. Furthermore, we approach about the authoritarianism heritage of the dictatorship period and its reflection in the processual practices rectifying a procedure that violates the rights and a law highly selective and segregationist. Lastly, our work is product of a qualitative and bibliographic research, concluding with a view towards the urgent necessity of change on the formation of the Law professionals, humanizing them. When this happens, there is a criminal justice system that effectively seeks justice with equality, guaranteeing all members of the Brazilian Justice System in the search for a just decision.Citizenship.

It is an essay produced through appreciation (KAUFMANN, 2013) as a support for the understanding of the discourses, which have different meanings. The Brazilian university was born in the 1930s, with vocation and nature for the practice of general culture, scientific research and professional training (DECREE 19.851 / 1931). The National Faculty of Philosophy, the place of origin of the Pedagogy course, also presented this vocation (DECREE-LAW No. 1,190 / 1931), but did not include the research in the curriculum of the course. This contradiction provoked a historical noise, so much so that, in 1962, research emerged as an optional discipline in the Pedagogy course (OPINION no. 251/1962), suffering interruption six years later, with the implementation of the military dictatorship. This interruption also became noisy until the 1980s, when, due to political openness and the movements of educators, the reflections and clashes about teacher education were resurfaced. The educators, through ANFOPE, materialized new formative proposals and conferred on the research, together with teaching and management, the condition of formative principle and course identity. The research was done legally with the DCN-CP (RESOLUTION No. 01/2006). Search. University. Course of Pedagogy.

The existence of nociceptive-specific brain regions has been a controversial issue for decades. Multisensory fMRI studies, which examine fMRI activities in response to various types of sensory stimulation, could help identify nociceptive-specific brain regions, but previous studies are limited by sample size and they did not differentiate nociceptive-specific regions and nociceptive-preferential regions, which have significantly larger responses to nociceptive input. In this study, we conducted a multisensory fMRI experiment on 80 healthy participants, with the aim to determine whether there are certain brain regions that specifically or preferentially respond to nociceptive stimulation. By comparing the evoked fMRI responses across four sensory modalities, we found a series of brain regions specifically or preferentially involved in nociceptive sensory input. Particularly, we found different parts of some cortical regions, such as insula and cingulate gyrus, play different functional roles in the processing of nociceptive stimulation. Hence, this multisensory study improves our understanding of the functional integrations and segregations of the nociceptive-related regions.

The literature on the persistence of racial residential segregation in the United States has made significant progress by moving beyond traditional explanations—socioeconomic differences, preferences, and discrimination—to focus on the complex ways in which these factors interact with the multistage process of residential sorting. Dramatic changes in metropolitan landscapes over the past two decades, however, demand an expanded theoretical framework that can account for stability and change. In this article, we review research on contemporary urban changes that offers insights for explaining segregation's persistence amid widespread change. We identify three broad categories of mechanisms that exacerbate inequities by race and class in residential sorting processes: resource inequality, hierarchy endurance, and consolidated power. We describe developments in measuring segregation and new data and methods for studying urban change that enable researchers to consider the contemporary mechanisms, forms, and scales of segregation in the twenty-first century. Expected final online publication date for the Annual Review of Sociology, Volume 48 is July 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Abstract Background: Salih myopathy, characterised by both congenital myopathy and fatal dilated cardiomyopathy, is an inherited muscle disorder that affects skeletal and cardiac muscles. TTN has been identified as the main cause of this myopathy, the enormous size of this gene poses a formidable challenge to molecular genetic diagnostics. Method: In the present study, whole-exome sequencing, cardiac MRI, and metabolic parameter assessment were performed to investigate the genetic causes of Salih myopathy in a consanguineous Iranian family who presented with titinopathy involving both skeletal and heart muscles in an autosomal recessive inheritance pattern. Results: Two missense variants of TTN gene (NM_001267550.2), namely c.61280A>C (p. Gln20427Pro) and c.54970G>A (p. Gly18324Ser), were detected and segregations were confirmed by polymerase chain reaction-based Sanger sequencing. Conclusions: The compound heterozygous variants, c.61280A>C, (p. Gln20427Pro) and c.54970G>A, (p. Gly18324Ser) in the TTN gene appear to be the cause of Salih myopathy and dilated cardiomyopathy in the family presented. Whole-exome sequencing is an effective molecular diagnostic tool to identify the causative genetic variants of large genes such as TTN.

PurposeTo identify novel genetic causes of febrile seizures (FS) and epilepsy with febrile seizures plus (EFS+).MethodsWe performed whole-exome sequencing in a cohort of 32 families, in which at least two individuals were affected by FS or EFS+. The probands, their parents, and available family members were recruited to ascertain whether the genetic variants were co-segregation. Genes with repetitively identified variants with segregations were selected for further studies to define the gene-disease association.ResultsWe identified two heterozygous ATP6V0C mutations (c.64G &gt; A/p.Ala22Thr and c.361_373del/p.Thr121Profs*7) in two unrelated families with six individuals affected by FS or EFS+. The missense mutation was located in the proteolipid c-ring that cooperated with a-subunit forming the hemichannel for proton transferring. It also affected the hydrogen bonds with surround residues and the protein stability, implying a damaging effect. The frameshift mutation resulted in a loss of function by yielding a premature termination of 28 residues at the C-terminus of the protein. The frequencies of ATP6V0C mutations identified in this cohort were significantly higher than that in the control populations. All the six affected individuals suffered from their first FS at the age of 7–8 months. The two probands later manifested afebrile seizures including myoclonic seizures that responded well to lamotrigine. They all displayed favorable outcomes without intellectual or developmental abnormalities, although afebrile seizures or frequent seizures occurred.ConclusionThis study suggests that ATP6V0C is potentially a candidate pathogenic gene of FS and EFS+. Screening for ATP6V0C mutations would help differentiating patients with Dravet syndrome caused by SCN1A mutations, which presented similar clinical manifestation but different responses to antiepileptic treatment.

“There is nothing more public than privacy.” (Berlant and Warner, Sex) How did it come to this? How did it happen that a one-off, two-hour event at a public swimming pool in a suburb of outer Melbourne ignited international hate mail and generated media-fanned political anguish and debate about the proper use of public spaces? In 2010, women who attend a women’s only swim session on Sunday evenings at the Dandenong Oasis public swimming pool asked the pool management and the local council for permission to celebrate the end of Ramadan at the pool during the time of their regular swim session. The request was supported by the pool managers and the council and promoted by both as an opportunity for family and friends to get together in a spirit of multicultural learning and understanding. Responding to criticisms of the event as an unreasonable claim on public facilities by one group, the Mayor of the City of Greater Dandenong, Jim Memeti, rejected claims that this event discriminates against non-Muslim residents of the suburb. But here’s the rub. The event, to be held after hours at the pool, requires all participants older than ten years of age to follow a dress code of knee-length shorts and T-shirts. This is a suburban moment that is borne of but exceeds the local. It reflects and responds to a contemporary global conundrum of great political and theoretical significance—how to negotiate and govern the relations between multiculturalism, religion, gender, sexual freedom, and democracy. Specifically this event speaks to how multicultural democracy in the public sphere negotiates the public presence and expression of different cultural and religious frameworks related to gender and sexuality. This is demanding political stuff. Situated in the messy political and theoretical terrains of the relation between public space and the public sphere, this local moment called for political judgement about how cultural differences should be allowed to manifest in and through public space, giving consideration to the potential effects of these decisions on an inclusive multicultural democracy. The local authorities in Dandenong engaged in an admirable process of democratic labour as they puzzled over how to make decisions that were responsible and equitable, in the absence of a rulebook or precedents for success. Ultimately however this mode of experimental decision-making, which will become increasingly necessary to manage such predicaments in the future, was foreclosed by unwarranted and unhelpful media outrage. "Foreclosed" here stresses the preemptive nature of the loss; a lost opportunity for trialing approaches to governing cultural diversity that may fail, but might then be modified. It was condemned in advance of either success or failure. The role of the media rather than the discomfort of the local publics has been decisive in this event.This Multicultural SuburbDandenong is approximately 30 kilometres southeast of central Melbourne. Originally home to the Bunorong People of the Kulin nation, it was settled by pastoralists by the 1800s, heavily industrialised during the twentieth century, and now combines cultural diversity with significant social disadvantage. The City of Greater Dandenong is proud of its reputation as the most culturally and linguistically diverse municipality in Australia. Its population of approximately 138,000 comprises residents from 156 different language groups. More than half (56%) of its population was born overseas, with 51% from nations where English is not the main spoken language. These include Vietnam, Cambodia, Sri Lanka, India, China, Italy, Greece, Bosnia and Afghanistan. It is also a place of significant religious diversity with residents identifying as Buddhist (15 per cent) Muslim (8 per cent), Hindu (2 per cent) and Christian (52 per cent) [CGD]. Its city logo, “Great Place, Great People” evokes its twin pride in the placemaking power of its diverse population. It is also a brazen act of civic branding to counter its reputation as a derelict and dangerous suburb. In his recent book The Bogan Delusion, David Nichols cites a "bogan" website that names Dandenong as one of Victoria’s two most bogan areas. The other was Moe. (p72). The Sunday Age newspaper had already depicted Dandenong as one of two excessively dangerous suburbs “where locals fear to tread” (Elder and Pierik). The other suburb of peril was identified as Footscray.Central Dandenong is currently the site of Australia’s largest ever state sponsored Urban Revitalisation program with a budget of more than $290 million to upgrade infrastructure, that aims to attract $1billion in private investment to provide housing and future employment.The Cover UpIn September 2010, the Victorian and Civil and Administrative Appeals Tribunal (VCAT) granted the YMCA an exemption from the Equal Opportunity Act to allow a dress code for the Ramadan event at the Oasis swimming pool that it manages. The "Y" sees the event as “an opportunity for the broader community to learn more about Ramadan and the Muslim faith, and encourages all members of Dandenong’s diverse community to participate” (YMCA Ramadan). While pool management and the municipal council refer to the event as an "opening up" of the closed swimming session, the media offer a different reading of the VCAT decision. The trope of the "the cover up" has framed most reports and commentaries (Murphy; Szego). The major focus of the commentaries has not been the event per se, but the call to dress "appropriately." Dress codes however are a cultural familiar. They exist for workplaces, schools, nightclubs, weddings, racing and sporting clubs and restaurants, to name but a few. While some of these codes or restrictions are normatively imposed rather than legally required, they are not alien to cultural life in Australia. Moreover, there are laws that prohibit people from being meagerly dressed or naked in public, including at beaches, swimming pools and so on. The dress code for this particular swimming pool event was, however, perceived to be unusual and, in a short space of time, "unusual" converted to "social threat."Responses to media polls about the dress code reveal concerns related to the symbolic dimensions of the code. The vast majority of those who opposed the Equal Opportunity exemption saw it as the thin edge of the multicultural wedge, a privatisation of public facilities, or a denial of the public’s right to choose how to dress. Tabloid newspapers reported on growing fears of Islamisation, while the more temperate opposition situated the decision as a crisis of human rights associated with tolerating illiberal cultural practices. Julie Szego reflects this view in an opinion piece in The Age newspaper:the Dandenong pool episode is neither trivial nor insignificant. It is but one example of human rights laws producing outcomes that restrict rights. It raises tough questions about how far public authorities ought to go in accommodating cultural practices that sit uneasily with mainstream Western values. (Szego)Without enquiring into the women’s request and in the absence of the women’s views about what meaning the event held for them, most media commentators and their electronically wired audiences treated the announcement as yet another alarming piece of evidence of multicultural failure and the potential Islamisation of Australia. The event raised specific concerns about the double intrusion of cultural difference and religion. While the Murdoch tabloid Herald Sun focused on the event as “a plan to force families to cover up to avoid offending Muslims at a public event” (Murphy) the liberal Age newspaper took a more circumspect approach, reporting on its small vox pop at the Dandenong pool. Some people here referred to the need to respect religions and seemed unfazed by the exemption and the event. Those who disagreed thought it was important not to enforce these (dress) practices on other people (Carey).It is, I believe, significant that several employees of the local council informed me that most of the opposition has come from the media, people outside of Dandenong and international groups who oppose the incursion of Islam into non-Islamic settings. Opposition to the event did not appear to derive from local concern or opposition.The overwhelming majority of Herald Sun comments expressed emphatic opposition to the dress code, citing it variously as unAustralian, segregationist, arrogant, intolerant and sexist. The Herald Sun polled readers (in a self-selecting and of course highly unrepresentative on-line poll) asking them to vote on whether or not they agreed with the VCAT exemption. While 5.52 per cent (512 voters) agreed with the ruling, 94.48 per cent (8,760) recorded disagreement. In addition, the local council has, for the first time in memory, received a stream of hate-mail from international anti-Islam groups. Muslim women’s groups, feminists, the Equal Opportunity Commissioner and academics have also weighed in. According to local reports, Professor of Islamic Studies at the University of Melbourne, Shahram Akbarzadeh, considered the exemption was “nonsense” and would “backfire and the people who will pay for it will be the Muslim community themselves” (Haberfield). He repudiated it as an example of inclusion and tolerance, labeling it “an effort of imposing a value system (sic)” (Haberfield). He went so far as to suggest that, “If Tony Abbott wanted to participate in his swimwear he wouldn’t be allowed in. That’s wrong.” Tasneem Chopra, chairwoman of the Islamic Women’s Welfare Council and Sherene Hassan from the Islamic Council of Victoria, both expressed sensitivity to the group’s attempt to establish an inclusive event but would have preferred the dress code to be a matter of choice rather coercion (Haberfield, "Mayor Defends Dandenong Pool Cover Up Order"). Helen Szoke, the Commissioner of the Victorian Equal Opportunity and Human Rights Commission, defended the pool’s exemption from the Law that she oversees. “Matters such as this are not easy to resolve and require a balance to be achieved between competing rights and obligations. Dress codes are not uncommon: e.g., singlets, jeans, thongs etc in pubs/hotels” (in Murphy). The civil liberties organisation, Liberty Victoria, supported the ban because the event was to be held after hours (Murphy). With astonishing speed this single event not only transformed the suburban swimming pool to a theatre of extra-local disputes about who and what is entitled to make claims on public space and publically funded facilities, but also fed into charged debates about the future of multiculturalism and the vulnerability of the nation to the corrosive effects of cultural and religious difference. In this sense suburbs like Dandenong are presented as sites that not only generate fear about physical safety but whose suburban sensitivities to its culturally diverse population represent a threat to the safety of the nation. Thus the event both reflects and produces an antipathy to cultural difference and to the place where difference resides. This aversion is triggered by and mediated in this case through the figure, rather than the (corpo)reality, of the Muslim woman. In this imagining, the figure of the Muslim woman is assigned the curious symbolic role of "cultural creep." The debates around the pool event is not about the wellbeing or interests of the Muslim women themselves, nor are broader debates about the perceived, culturally-derived restrictions imposed on Muslim women living in Australia or other western countries. The figure of the Muslim woman is, I would argue, simply the ground on which the debates are held. The first debate relates to social and public space, access to which is considered fundamental to freedom and participatory democracy, and in current times is addressed in terms of promoting inclusion, preventing exclusion and finding opportunities for cross cultural encounters. The second relates not to public space per se, but to the public sphere or the “sphere of private people coming together as a public” for political deliberation (Habermas 21). The literature and discussions dealing with these two terrains have remained relatively disconnected (Low and Smith) with public space referring largely to activities and opportunities in the socio-cultural domain and the public sphere addressing issues of politics, rights and democracy. This moment in Dandenong offers some modest leeway for situating "the suburb" as an ideal site for coalescing these disparate discussions. In this regard I consider Iveson’s provocative and productive question about whether some forms of exclusions from suburban public space may actually deepen the democratic ideals of the public sphere. Exclusions may in such cases be “consistent with visions of a democratically inclusive city” (216). He makes his case in relation to a dispute about the exclusion of men exclusion from a women’s only swimming pool in the Sydney suburb of Coogee. The Dandenong case is similarly exclusive with an added sense of exclusion generated by an "inclusion with restrictions."Diversity, Difference, Public Space and the Public SphereAs a prelude to this discussion of exclusion as democracy, I return to the question that opened this article: how did it come to this? How is it that Australia has moved from its renowned celebration and pride in its multiculturalism so much in evidence at the suburban level through what Ghassan Hage calls an “unproblematic” multiculturalism (233) and what others have termed “everyday multiculturalism” (Wise and Velayutham). Local cosmopolitanisms are often evinced through the daily rituals of people enjoying the ethnic cuisines of their co-residents’ pasts, and via moments of intercultural encounter. People uneventfully rub up against and greet each other or engage in everyday acts of kindness that typify life in multicultural suburbs, generating "reservoirs of hope" for democratic and cosmopolitan cities (Thrift 147). In today’s suburbs, however, the “Imperilled Muslim women” who need protection from “dangerous Muslim men” (Razack 129) have a higher discursive profile than ethnic cuisine as the exemplar of multiculturalism. Have we moved from pleasure to hostility or was the suburban pleasure in racial difference always about a kind of “eating the other” (bell hooks 378). That is to ask whether our capacity to experience diversity positively has been based on consumption, consuming the other for our own enrichment, whereas living with difference entails a commitment not to consumption but to democracy. This democratic multicultural commitment is a form of labour rather than pleasure, and its outcome is not enrichment but transformation (although this labour can be pleasurable and transformation might be enriching). Dandenong’s prized cultural precincts, "Little India" and the "Afghan bazaar" are showcases of food, artefacts and the diversity of the suburb. They are centres of pleasurable and exotic consumption. The pool session, however, requires one to confront difference. In simple terms we can think about ethnic food, festivals and handicrafts as cultural diversity, and the Muslim woman as cultural difference.This distinction between diversity and difference is useful for thinking through the relation between multiculturalism in public space and multicultural democracy of the public sphere. According to the anthropologist Thomas Hylland Eriksen, while a neoliberal sensibility supports cultural diversity in the public space, cultural difference is seen as a major cause of social problems associated with immigrants, and has a diminishing effect on the public sphere (14). According to Eriksen, diversity is understood as aesthetic, or politically and morally neutral expressions of culture that are enriching (Hage 118) or digestible. Difference, however, refers to morally objectionable cultural practices. In short, diversity is enriching. Difference is corrosive. Eriksen argues that differences that emerge from distinct cultural ideas and practices are deemed to create conflicts with majority cultures, weaken social solidarity and lead to unacceptable violations of human rights in minority groups. The suburban swimming pool exists here at the boundary of diversity and difference, where the "presence" of diverse bodies may enrich, but their different practices deplete and damage existing culture. The imperilled Muslim woman of the suburbs carries a heavy symbolic load. She stands for major global contests at the border of difference and diversity in three significant domains, multiculturalism, religion and feminism. These three areas are positioned simultaneously in public space and of the public sphere and she embodies a specific version of each in this suburban setting. First, there a global retreat from multiculturalism evidenced in contemporary narratives that describe multiculturalism (both as official policy and unofficial sensibility) as failed and increasingly ineffective at accommodating or otherwise dealing with religious, cultural and ethnic differences (Cantle; Goodhart; Joppke; Poynting and Mason). In the UK, Europe, the US and Australia, popular media sources and political discourses speak of "parallel lives,"immigrant enclaves, ghettoes, a lack of integration, the clash of values, and illiberal cultural practices. The covered body of the Muslim woman, and more particularly the Muslim veil, are now read as visual signs of this clash of values and of the refusal to integrate. Second, religion has re-emerged in the public domain, with religious groups and individuals making particular claims on public space both on the basis of their religious identity and in accord with secular society’s respect for religious freedom. This is most evident in controversies in France, Belgium and Netherlands associated with banning niqab in public and other religious symbols in schools, and in Australia in court. In this sense the covered Muslim woman raises concerns and indignation about the rightful place of religion in the public sphere and in social space. Third, feminism is increasingly invoked as the ground from which claims about the imperilled Muslim woman are made, particularly those about protecting women from their dangerous men. The infiltration of the Muslim presence into public space is seen as a threat to the hard won gains of women’s freedom enjoyed by the majority population. This newfound feminism of the public sphere, posited by those who might otherwise disavow feminism, requires some serious consideration. This public discourse rarely addresses the discrimination, violation and lack of freedom experienced systematically on an everyday basis by women of majority cultural backgrounds in western societies (such as Australia). However, the sexism of racially and religiously different men is readily identified and decried. This represents a significant shift to a dubious feminist register of the public sphere such that: “[w]omen of foreign origin, ...more specifically Muslim women…have replaced the traditional housewife as the symbol of female subservience” (Tissot 41–42).The three issues—multiculturalism, religion and feminism—are, in the Dandenong pool context, contests about human rights, democracy and the proper use of public space. Szego’s opinion piece sees the Dandenong pool "cover up" as an example of the conundrum of how human rights for some may curtail the human rights of others and lead us into a problematic entanglement of universal "rights," with claims of difference. In her view the combination of human rights and multiculturalism in the case of the Dandenong Pool accommodates illiberal practices that put the rights of "the general public" at risk, or as she puts it, on a “slippery slope” that results in a “watering down of our human rights.” Ideas that entail women making a claim for private time in public space are ultimately not good for "us."Such ideas run counter to the West's more than 500-year struggle for individual freedom—including both freedom of religion and freedom from religion—and for gender equality. Our public authorities ought to be pushing back hardest when these values are under threat. Yet this is precisely where they've been buckling under pressure (Szego)But a different reading of the relation between public and private space, human rights, democracy and gender freedom is readily identifiable in the Dandenong event—if one looks for it. Living with difference, I have already suggested, is a problem of democracy and the public sphere and does not so easily correspond to consuming diversity, as it demands engagement with cultural difference. In what remains, I explore how multicultural democracy in the public sphere and women’s rights in public and private realms relate, firstly, to the burgeoning promise of democracy and civility that might emerge in public space through encounter and exchange. I also point out how this moment in Dandenong might be read as a singular contribution to dealing with this global problematic of living with difference; of democracy in the public sphere. Public urban space has become a focus for speculation among geographers and sociologists in particular, about the prospects for an enhanced civic appreciation of living with difference through encountering strangers. Random and repetitious encounters with people from all cultures typify contemporary urban life. It remains an open question however as to whether these encounters open up or close down possibilities for conviviality and understanding, and whether they undo or harden peoples’ fears and prejudices. There is, however, at least in some academic and urban planning circles, some hope that the "throwntogetherness" (Massey) and the "doing" of togetherness (Laurier and Philo) found in the multicultural city may generate some lessons and opportunities for developing a civic culture and political commitment to living with difference. Alongside the optimism of those who celebrate the city, the suburb, and public spaces as forging new ways of living with difference, there are those such as Gill Valentine who wonder how this might be achieved in practice (324). Ash Amin similarly notes that city or suburban public spaces are not necessarily “the natural servants of multicultural engagement” (Ethnicity 967). Amin and Valentine point to the limited or fleeting opportunities for real engagement in these spaces. Moreover Valentine‘s research in the UK revealed that the spatial proximity found in multicultural spaces did not so much give rise to greater mutual respect and engagement, but to a frustrated “white self-segregation in the suburbs.” She suggests therefore that civility and polite exchange should not be mistaken for respect (324). Amin contends that it is the “micro-publics” of social encounters found in workplaces, schools, gardens, sports clubs [and perhaps swimming pools] rather than the fleeting encounters of the street or park, that offer better opportunities for meaningful intercultural exchange. The Ramadan celebration at the pool, with its dress code and all, might be seen more fruitfully as a purposeful event engaging a micro-public in which people are able to “break out of fixed relations and fixed notions” and “learn to become different” (Amin, Ethnicity 970) without that generating discord and resentment.Micropublics, Subaltern Publics and a Democracy of (Temporary) ExclusionsIs this as an opportunity to bring the global and local together in an experiment of forging new democratic spaces for gender, sexuality, culture and for living with difference? More provocatively, can we see exclusion and an invitation to share in this exclusion as a precursor to and measure of, actually existing democracy? Painter and Philo have argued that democratic citizenship is questionable if “people cannot be present in public spaces (streets, squares, parks, cinemas, churches, town halls) without feeling uncomfortable, victimized and basically ‘out of place’…" (Iveson 216). Feminists have long argued that distinctions between public and private space are neither straightforward nor gender neutral. For Nancy Fraser the terms are “cultural classifications and rhetorical labels” that are powerful because they are “frequently deployed to delegitimate some interests, views and topics and to valorize others” (73). In relation to women and other subordinated minorities, the "rhetoric of privacy" has been historically used to restrict the domain of legitimate public contestation. In fact the notion of what is public and particularly notions of the "public interest" and the "public good" solidify forms of subordination. Fraser suggests the concept of "subaltern counterpublics" as an alternative to notions of "the public." These are discursive spaces where groups articulate their needs, and demands are circulated formulating their own public sphere. This challenges the very meaning and foundational premises of ‘the public’ rather than simply positing strategies of inclusion or exclusion. The twinning of Amin’s notion of "micro-publics" and Fraser’s "counterpublics" is, I suggest, a fruitful approach to interpreting the Dandenong pool issue. It invites a reading of this singular suburban moment as an experiment, a trial of sorts, in newly imaginable ways of living democratically with difference. It enables us to imagine moments when a limited democratic right to exclude might create the sorts of cultural exchanges that give rise to a more authentic and workable recognition of cultural difference. I am drawn to think that this is precisely the kind of democratic experimentation that the YMCA and Dandenong Council embarked upon when they applied for the Equal Opportunity exemption. I suggest that by trialing, rather than fixing forever a "critically exclusive" access to the suburban swimming pool for two hours per year, they were in fact working on the practical problem of how to contribute in small but meaningful ways to a more profoundly free democracy and a reworked public sphere. In relation to the similar but distinct example of the McIver pool for women and children in Coogee, New South Wales, Kurt Iveson makes the point that such spaces of exclusion or withdrawal, “do not necessarily serve simply as spaces where people ‘can be themselves’, or as sites through which reified identities are recognised—in existing conditions of inequality, they can also serve as protected spaces where people can take the risk of exploring who they might become with relative safety from attack and abuse” (226). These are necessary risks to take if we are to avoid entrenching fear of difference in a world where difference is itself deeply, and permanently, entrenched.ReferencesAmin, Ash. “Ethnicity and the Multicultural City: Living with Diversity.” Environment and Planning A 34 (2002): 959–80.———. “The Good City.” Urban Studies 43 (2006): 1009–23.Berlant, Lauren, and Michael Warner. “Sex in Public.” Critical Inquiry 24 (1998): 547–66.Cantle, Ted.
