Williams, Jill R., Enid J. Schatz, Benjamin D. Clark, Mark A. Collinson, Samuel J. Clark, Jane Menken, Kathleen Kahn, Stephen M. Tollman. 2010. “Improving public health training and research capacity in Africa: A replicable model for linking training to health and socio-demographic surveillance data.” Global Health Action 3, 5287. DOI: 10.3402/gha.v3i0.5287.
Abstract: Background: Research training for public health professionals is key to the future of public health and policy in Africa. A growing number of schools of public health are connected to health and socio-demographic surveillance system field sites in developing countries, in Africa and Asia in particular. Linking training programs with these sites provides important opportunities to improve training, build local research capacity, foreground local health priorities, and increase the relevance of research to local health policy. Objective: To increase research training capacity in public health programs by providing targeted training to students and increasing the accessibility of existing data. Design: This report is a case study of an approach to linking public health research and training at the University of the Witwatersrand. We discuss the development of a sample training database from the Agincourt Health and Socio-demographic Surveillance System in South Africa and outline a concordant transnational intensive short course on longitudinal data analysis offered by the University of the Witwatersrand and the University of Colorado-Boulder. This case study highlights ways common barriers to linking research and training can be overcome. Results and Conclusions: This collaborative effort demonstrates that linking training to ongoing data collection can improve student research, accelerate student training, and connect students to an international network of scholars. Importantly, the approach can be adapted to other partnerships between schools of public health and longitudinal research sites.
Kuhn, R. 2010. "Routes to Low Mortality in Poor Countries Revisited." Population and Development Review, 36: 655–692.
Abstract: In June 1986, Population and Development Review published a highly influential article by John Caldwell entitled “Routes to Low Mortality in Poor Countries.” Amid growing anxiety over decelerating world mortality decline, Caldwell explored social and political pathways to mortality success on the basis of two lists of superior mortality achievers and exceptionally poor mortality achievers, countries whose mortality rankings drastically differed from their income rankings. To mark the quarter-century since Caldwell's study and chart new pathways, this article looks at the subsequent performance of Caldwell's original exceptional achievers and develops an updated list of achievers. Analysis highlights the presence of many more poor achievers today; the rising importance of adult mortality as a marker of exceptional achievement; the increasing success of countries in Latin America and the Muslim world; the continued success of China, Vietnam, Cuba, and Costa Rica. dramatic improvements in schooling outcomes, particularly for women, have reduced the importance of education as a determinant of superior achievement. Reinforcing Caldwell's original assertions, the synthesis highlights how interactions between social consensus, health care systems, and human capital dependence offer a pathway to superior achievement. These forces may be especially powerful at moments of national crisis.
Hughes, Barry B., Randall Kuhn, Cecilia Mosca Peterson, Dale S. Rothman, Jose R. Solorzano. 2010. Improving Global Health: Patterns in Potential Human Progress. Volume 3. Boulder, CO: Paradigm Publishers.
Abstract: Improving Global Health is the third in a series of volumes—Patterns of Potential Human Progress—that uses the International Futures (IFs) simulation model to explore prospects for human development: how development appears to be unfolding globally and locally, how we would like it to evolve, and how better to assure that we move it in desired directions. Earlier volumes addressed the reduction of global poverty and the advance of global education. Volume 3 sets out to tell a story of possible futures for the health of peoples across the world. Questions the volume addresses include: • What health outcomes might we expect given current patterns of human development? • What opportunities exist for intervention and the achievement of alternate health futures? • How might improved health futures affect broader economic, social, and political prospects of countries, regions, and the world?
Schatz, Enid. 2009. "Reframing vulnerability: Mozambican refugees’ access to state-funded pensions in rural South Africa". Journal of Cross-Cultural Gerontology 24, no. 3 (2009)241-258.
Abstract: Researchers at the South African Medical Research Council/University of the Witwatersrand Rural Public Health and Health Transitions Research Unit (Agincourt) fieldsite in rural South Africa consider Mozambican residents more vulnerable than others in the local population. These self-settled refugees, many of whom are still not South African citizens, primarily came to South Africa in the 1980s during the Mozambican Civil War. This perceived economic vulnerability is rooted in their difficulties in accessing social grants, until recently legally available only to those with South African citizenship documentation. This paper focuses on semi-structured interviews with 30 ‘older’ women of Mozambican-descent living in the Agincourt area. These interviews highlight three important aspects of vulnerability; the respondents: (1) perceive a risk of deportation despite their having lived in the country for 20 years, (2) are unable to easily access social grants, namely the state-funded old-age pension, and (3) struggle to make ends meet when faced with daily needs and crisis situations. All three of these vulnerabilities were mediated to some extent by these women’s resourcefulness. They generated ties to South Africa through obtaining identification-documents, used these documents to access pensions, and used the pensions to help them sustain their multigenerational households.
Ogunmefun, Catherine and Enid Schatz. "Caregivers' sacrifices: the opportunity costs of adult morbidity and mortality for female pensioners in rural South Africa". Development Southern Africa 26, no. 1 (2009):95-109.
Abstract: This paper explores the financial and opportunity costs of adult morbidity and mortality for rural South African female pensioners in the era of HIV/AIDS. As mortality rates from HIV/AIDS and other causes escalate, older women are bearing the brunt of caregiving responsibilities for the sick and orphaned. They often use their state-funded non-contributory pensions to support kin during crises. Interviews conducted with 30 women aged 60-75 years in the Medical Research Council/University of the Witwatersrand Unit (Agincourt) study site in northeastern South Africa revealed that, to cover expenses incurred during crises, older women sometimes forgo spending money and time on their personal needs. They are thus negatively affected as individuals, while contributing positively to the household. Despite the additional household income from pensions, many of the study respondents still found it difficult to recover from the financial impact of these crises.
Reniers, Georges, Tekebash Araya, Yemane Berhane, Gail Davey and Eduard J Sanders. "Implications of the HIV testing protocol for refusal bias in seroprevalence surveys". BMC Public Health 2009, 9:163
Abstract: Background: HIV serosurveys have become important sources of HIV prevalence estimates, but these estimates may be biased because of refusals and other forms of non-response. We investigate the effect of the post-test counseling study protocol on bias due to the refusal to be tested. Methods: Data come from a nine-month prospective study of hospital admissions in Addis Ababa during which patients were approached for an HIV test. Patients had the choice between three consent levels: testing and post-test counseling (including the return of HIV test results), testing without post-test counseling, and total refusal. For all patients, information was collected on basic sociodemographic background characteristics as well as admission diagnosis. The three consent levels are used to mimic refusal bias in serosurveys with different post-test counseling study protocols. We first investigate the covariates of consent for testing. Second, we quantify refusal bias in HIV prevalence estimates using Heckman regression models that account for sample selection. Results: Refusal to be tested positively correlates with admission diagnosis (and thus HIV status), but the magnitude of refusal bias in HIV prevalence surveys depends on the study protocol. Bias is larger when post-test counseling and the return of HIV test results is a prerequisite of study participation (compared to a protocol where test results are not returned to study participants, or, where there is an explicit provision for respondents to forego post-test counseling). We also find that consent for testing increased following the introduction of antiretroviral therapy in Ethiopia. Other covariates of refusal are age (non-linear effect), gender (higher refusal rates in men), marital status (lowest refusal rates in singles), educational status (refusal rate increases with educational attainment), and counselor. Conclusion: The protocol for post-test counseling and the return of HIV test results to study participants is an important consideration in HIV prevalence surveys that wish to minimize refusal bias. The availability of ART is likely to reduce refusal rates.
Boileau, C., S. Clark, S. Bignami-Van Assche, M. Poulin, G. Reniers, S. C. Watkins, H. P. Kohler, and S. J. Heymann. "Sexual and marital trajectories and HIV infection among ever-married women in rural Malawi". Sexually Transmitted Infections 85(Suppl 1)(2009):i27-i33
Abstract: Objective: To explore how sexual and marital trajectories are associated with HIV infection among ever-married women in rural Malawi. Methods: Retrospective survey data and HIV biomarker data for 926 ever-married women interviewed in the Malawi Diffusion and Ideational Change Project were used. The associations between HIV infection and four key life course transitions considered individually (age at sexual debut, premarital sexual activity, entry into marriage and marital disruption by divorce or death) were examined. These transitions were then sequenced to construct trajectories that represent the variety of patterns in the data. The association between different trajectories and HIV prevalence was examined, controlling for potentially confounding factors such as age and region. Results: Although each life course transition taken in isolation may be associated with HIV infection, their combined effect appeared to be conditional on the sequence in which they occurred. Although early sexual debut, not marrying one’s first sexual partner and having a disrupted marriage each increased the likelihood of HIV infection, their risk was not additive. Women who both delayed sexual debut and did not marry their first partner are, once married, more likely to experience marital disruption and to be HIV-positive. Women who marry their first partner but who have sex at a young age, however, are also at considerable risk. Conclusions: These findings identify the potential of a life course perspective for understanding why some women become infected with HIV and others do not, as well as the differentials in HIV prevalence that originate from the sequence of sexual and marital transitions in one’s life. The analysis suggests, however, the need for further data collection to permit a better examination of the mechanisms that account for variations in life course trajectories and thus in lifetime probabilities of HIV infection.
Williams, Jill. “Spatial Transversals: Gender, Race, Class and Gay Tourism in Cape Town, South Africa.” Race, Gender and Class: An Interdisciplinary and Multicultural Journal 15, no. 1-2(2008):58-78.
Abstract: This paper examines the circulation of gay capital within gay and lesbian tourism in Cape Town, South Africa. Using participant observation of a gay shebeen tour as an example, the author describes new forms of gay and lesbian tourist-activism emerging in Cape Town and analyzes their impact on the racialized spatial economy of gay leisure space. Taking the complicity with capitalism inherent in tourism for granted, it is demonstrated that capitalist impulses mediated by activist motivations can create radical, even anti-colonial, social moments, and argued that in the context of South Africa it is particularly noteworthy that emerging forms of “queer capitalist tourism” are disrupting class and racial boundaries in ways not accomplished through the political activism that resulted in the inclusion of constitutional protections against discrimination based on sexual orientation. Amid increasingly visible and violent homophobia, queer capitalist tourism is facilitating transversal queer alliances and making important contributions to building a grassroots movement that can unite the previously fragmented gay and lesbian communities in South Africa.
Madhavan, Sangeetha and Enid J. Schatz.. "Coping with change: Household structure and composition in rural South Africa, 1992 - 2003." Scandinavian Journal of Public Health 35, no. S69 (2007): 85–93.
Abstract: Aim: To describe household change over a 10-year period of tremendous social, political, economic and health transformation in South Africa using data from the Agincourt health and demographic surveillance system in the rural northeast of South Africa. Methods: Examination of household structure and composition at three points: 1992, 1997, and 2003. These three years loosely represent conditions immediately before the elections (1992), short term post-elections (1997), and longer term (2003), and span a period of notable increase in HIV prevalence. Results: Average household size decreased and the proportion headed by females increased. The within-household dependency ratios for children and elders both decreased, as did the proportion of households containing foster children. The proportion with at least one maternal orphan doubled, but was still relatively small at 5.5%. Conclusions: This analysis is a starting point for future investigations aimed at explaining how HIV/AIDS and other sociocultural changes post-apartheid have impacted on household organization. The analysis shows both consistency and change in measures of household structure and composition between 1992 and 2003. The changes do not include an increase in various types of "fragile families", such as child-headed or skipped-generation households that might be expected due to HIV/AIDS.
Enid J. Schatz. "Taking care of my own blood": Older women's relationships to their households in rural South Africa." Scandinavian Journal of Public Health 35, no. S69 (2007): 147 - 154.
Abstract: Aim: This paper examines financial, emotional, and physical responsibilities elderly women are being asked to take on due to the incapacity of their adult children to care for the next generation; such incapacity is likely to increase as the HIV/AIDS epidemic worsens. Methods: This paper combines quantitative and qualitative data. Census data from the Agincourt health and demographic surveillance system (AHDSS) describe the presence of the elderly (specifically women over the age of 60 and men over the age of 65) in households in the Agincourt study site. Semi-structured interviews with 30 female residents aged 60-75 complement the census data by exploring the roles that older women, in particular, are playing in their households. Results: An elderly man and/or woman lives in 27.6% of households; 86% of elders live with non-elders. Households with a woman over the age of 60 resident (as opposed to those without) are twice as likely to have a fostered child living in the household and three times as likely to have an orphaned child in the household. Elderly women face financial, physical, and emotional burdens related to the morbidity and mortality of their adult children, and to caring for grandchildren left behind due to adult children's mortality, migration, (re)marriage, and unemployment. Conclusions: Older women provide crucial financial, physical, and emotional support for ill adult children and fostered and orphaned grandchildren in their households. As more prime-aged adults suffer from HIV/AIDS-related morbidity and mortality, these obligations are likely to increase.
Schatz, Enid J. and Catherine Ogunmefun. "Caring and Contributing: The Role of Older Women in Rural South African Multi-generational Households in the HIV/AIDS Era." World Development 35, no. 8 (2007): 1390-1403.
Abstract: This paper explores households’ coping strategies in rural South Africa, where HIV/AIDS morbidity and mortality are having profound effects on household resources. Older women’s pensions play a potentially crucial role in multi-generational households during crises and for day-to-day subsistence. We conducted semi-structured interviews with 30 elderly women from the MRC/Wits Rural Public Health and Health Transitions Research Unit (Agincourt) fieldsite, who were eligible for the South African non-contributory pension. Although we stratified our sample by household mortality experience, the area’s high levels of migration, unemployment, and HIV/AIDS prevalence made our respondents’ pensions an important, regular, and reliable source of household-income regardless of their households’ mortality profile.

Young, J. T., Jane Menken, Jill Williams, Nizam Khan and Randall S. Kuhn. "Who Receives Healthcare? Age and Sex Differentials in Adult Use of Healthcare Services in Rural Bangladesh." World Health and Population (2006).
Abstract: Use of healthcare services may vary according to the cultural, social, economic and demographic situation of the person who may need care. In certain contexts, it particularly varies with age and sex of the potential user. Bangladesh is a less developed, primarily rural and predominantly Muslim traditional society with a pluralistic healthcare system. This paper endeavours to delineate the age, sex and other factors associated with obtaining healthcare in this pluralistic system. Using the Matlab Health and Socio-economic Survey, the paper uses logistic regression to ask whether factors commonly related to Western healthcare utilization in a theoretical framework useful in the study of Western research on healthcare services are also useful in the study of healthcare utilization in the developing world. Elderly women, never-married women and Hindus were less likely to visit any practitioner, which may indicate less health empowerment for these groups. Obtaining care is inversely related to household size and positively related to age (for men), education, poor health status and impaired mobility. Controlling for these factors, household wealth and ever-married status showed no significant effect on obtaining care. The differential in use of healthcare services can partially be ameliorated by changes in policy related to the elderly and women.

Abstract: Demographic and health surveillance (DS) systems monitor and document individual- and group-level processes in well-defined populations over long periods of time. The resulting data are complex and inherently temporal. Established methods of storing and manipulating temporal data are unable to adequately address the challenges posed by these data. Building on existing standards, a temporal framework and notation are presented that are able to faithfully record all of the time-related information (or partial lack thereof) produced by surveillance systems. The Unified Timestamp isolates all of the inherent complexity of temporal data into a single data type and provides the foundation on which a Unified Timestamp class can be built. The Unified Timestamp accommodates both point- and interval-based time measures with arbitrary precision, including temporal sets. Arbitrary granularities and calendars are supported, and the Unified Timestamp is hierarchically organized, allowing it to represent an unlimited array of temporal entities.
Kuhn, Randall. "A Longitudinal Analysis of Health and Mortality in a Migrant-Sending Region of Bangladesh." In Migration and Health in Asia, edited by Santosh Jatrana, Mika Toyota, and Brenda S.A. Yeoh. London: Routledge, 2005.
Abstract: Twelve specialist essays explore health aspects of the migration of workers which is now an established feature of Asia's socio-economy. The matters addressed include: implications for the spread of Aids in Indonesia; relocation of the Akha people in Northwest Laos; foreign labour migrants and SARS in Singapore; role of nativity in Singapore's elder-health; maternal anaemia in the Visayas, the Philippines; Filipinos in Sabah; migration differentials in healthcare in Japan; migration and health within China; migrant-sending area's health in Bangladesh; reproductive health of wives of out-migrants in Bihar. The final papers draw general conclusions very useful to policy planners and administrators as well as to those directly concerned with health matters. With bibliography and index.
Kuhn, Randall, and Steven Stillman. "Understanding Interhousehold Transfers in a Transition Economy: Evidence from Russia." Economic Development and Cultural Change 53, no. 1 (2004): 131-56.
Abstract: This paper uses data from the Russian Longitudinal Monitoring Survey (RLMS) to describe and model the determinants of interhousehold transfers. Russian households have experienced large reductions in income during the transition period, with a particularly severe decline occurring in the fall of 1998. Russia is experiencing a most unique pattern of aging. Sharply declining fertility, increasing mortality, and past demographic catastrophes (the two World Wars and the famine of the 1930’s) has left a population which is both young (few elderly) and old (one of the oldest working-age populations in the world). While Russia’s economic institutions and social safety net are underdeveloped, the typical household structure closely resembles that found in wealthier countries. Although it is typically assumed that the elderly in Russia are a highly vulnerable economic group, we actually find that transfers flow strongly from the elderly to their children, who are typically in the early part of the life-course and often have young children. This is especially true for the elderly in rural areas and those in extended families. While households with higher longer-term resources receive on net more transfers, we also find strong evidence that transfers respond to economic needs (i.e. transitory fluctuations in resources).

Abstract: The authors examine the relationships between body mass, smoking, and overall and cause-specific mortality among U.S. adults aged 60 and older, using data from the National Health Interview Survey linked to the Multiple Cause of Death file and Cox proportional hazard models. The authors find that, compared to those who are normal weight, obese individuals have higher risks of overall, circulatory disease, and diabetes mortality. Furthermore, smoking status suppresses the relationships between obesity and overall, circulatory disease, and cancer mortality, and interacts with low body weight to increase mortality risks. Finally, underweight individuals initially face increased risks of death over the follow-up period, although over time their mortality risks diminish to those of normal-weight individuals, likely due to the presence of unobserved illness. Researchers and health practitioners must account for smoking status, body mass, and specific causes of death to understand and improve the health of our increasingly obese elderly population.
Denney, Justin T., Patrick M. Krueger, Richard G. Rogers, and Jason D. Boardman. "Race/Ethnic and Sex Differentials in Body Mass among US Adults." Ethnicity & Disease 14, no. 3 (2004): 389-98.
Abstract: Current research incompletely documents race/ethnic and sex disparities in body mass, especially at the national level. Data from the 2000 National Health Interview Survey, Sample Adult File, are used to examine overall and sex-specific disparities in body mass for non-Hispanic Whites, non-Hispanic Blacks, Native Americans, Asian Americans, Puerto Ricans, Mexican Americans, and Cuban Americans. Two complementary multivariate regression techniques, ordinary least squares and multinomial logistic, are employed to control for important confounding factors. We found significantly higher body masses for non-Hispanic Blacks, Native Americans, Puerto Ricans, and Mexican Americans, compared to non-Hispanic Whites. Among very obese individuals, these relationships were more pronounced for females. Given the known health consequences associated with overweight and obesity, and recent trends toward increasing body mass in the United States, these findings underscore the need for public health policies that target specific subpopulations, in order to close the wide disparities in body mass in the United States.
Silvey, Rachel. "A Wrench in the Global Works: Anti-Sweatshop Activism on Campus." Antipode 36, no. 2 (2004): 191-97.
Abstract: When students galvanized anti-sweatshop activism on US and Canadian university campuses in the late 1990s, their actions struck at the core of recent debates about the geographies of counter-hegemonic politics (Blunt and Wills 2000; Herod and Wright 2002; Miller 2000; Sharp et al 2000; Traub-Werner and Cravey 2002). Students staged rallies and sit-ins to challenge their universities’ complicity with the corporate exploitation and abuse of low-wage workers in factories overseas. They directed attention to the embeddedness of academic institutions in the systems that perpetuate global economic inequality, and signaled the re-emergence of students as vocal, vibrant political actors. Observers have celebrated the anti-sweatshop movement’s capacity to build transnational alliances across difference, influence the shape of labor internationalism, link distant nodes in regimes of accumulation, and in some cases even jump scale from the grassroots to international regulatory institutions. Indeed, the movement is cause for optimism among geographers who seek new approaches to the injustices wrought by neoliberal globalization.
Silvey, Rachel. "Transnational Migration and the Gender Politics of Scale: Indonesian Domestic Workers in Saudi Arabia, 1997-2000." Singapore Journal of Tropical Geography 25, no. 2 (2004): 141-55.
Abstract: Recent research has begun to explore the dynamics of transnational migration from a feminist perspective, and studies of migrant domestic workers have played a prominent role in pushing forward this work. Emerging simultaneously, but largely separately, are explicit debates within geography about the politics of scale, the social construction of scale, and the gender dimensions of scale. This article develops an analysis of the gender politics of the production of scale, specifically, the ‘transnationalisation’ of Indonesian activist approaches to overseas migrant domestic workers' issues. Based on fieldwork in an Indonesian community in West Java that has recently become a sending area for migrants to Saudi Arabia and interviews with activists representing Indonesian migrant women, the article examines the various gender-specific ways in which migrant women's rights activists construct and deploy the scales of the body, the nation and the transnational. It argues that activist approaches to migrant domestic workers' rights and the ways in which activists mobilise migrant women's narratives represent sophisticated feminist theoretical approaches to scale. By identifying and exploring the scale theory embedded in activist strategies, the analysis highlights the imbrication of feminist theory with practice, and underscores activists' agency in producing the meanings of specific scales. In so doing, the article is aimed more broadly at elaborating the ambivalent relationship between feminist activism/theory and transnationalism.
Silvey, Rachel. "Power, Difference, and Mobility: Feminist Advances in Migration Studies." Progress in Human Geography 28, no. 4 (2004): 1-17.
Abstract: The feminist migration literature in geography has contributed to bringing several critical social theoretical themes to the forefront of migration studies. Specifically, feminists have foregrounded: the politics of scale, mobility as political process, questions of subjectivity/identity, and critical theorizations of space and place. This article provides an overview of the feminist migration literature organized around these themes. In addition, it argues that feminist migration studies can play a pivotal role in the on-going project of marrying materialist approaches to political-economy with those of critical social theorists.
Rogers, Andrei, and Lisa Jordan. "Estimating Migration Flows from Birthplace-Specific Population Stocks of Infants." Geographical Analysis 36, no. 1 (2004): 38-53.
Abstract: When adequate data on migration are unavailable, demographers infer such data indirectly, usually by turning to residual methods of estimating net migration. This paper sets out and illustrates an inferential method that uses population totals in the first age group of birthplace-specific counts of residents in each region of a multiregional system to indirectly infer the entire age schedule of directional age-specific migration flows. Specifically, it uses an estimate of infant migration that is afforded by a count of infants enumerated in a region other than their region of birth to infer all other age-specific migration flows. Since infants migrate with their parents, the migration propensities of both are correlated, and the general stability of the age profiles of migration schedules then allows the association to be extended to all other age groups.
Krueger, Patrick M., Richard G. Rogers, Cristobal Ridao-Cano, and R. A. Hummer. "To Help or to Harm? Food Stamp Receipt and Mortality Risk Prior to the 1996 Welfare Reform Act." Social Forces 82, no. 4 (2004): 1573-99.
Abstract: The authors use data from the National Health Interview Survey-Family Resources Supplement to examine the relationship between Food Stamp receipt and prospective adult mortality, among eligible households. They specify a switching probit model to adjust for observed and unobserved factors that correlate with selection into the Food Stamp Program and mortality, and to estimate mortality under counterfactual conditions that we do not observe. The average individual, based on observed characteristics, has higher mortality when participating than when not participating. But due to unobserved differences between participants and nonparticipants, those who self-select into participation experience lower mortality than if they did not participate. Our findings suggest that Food Stamps provide an important safety net that protects the health of those who are most likely to participate.
Silvey, Rachel. "Transnational Domestication: State Power and Indonesian Migrant Women in Saudi Arabia." Political Geography 23, no. 3 (2004): 245-64.
Abstract: Recent efforts to elaborate a feminist geopolitics have centered on challenging and expanding classical spatializations of "the political." Building on this growing body of work, this article explores the gender politics of state power as refracted in struggles over women’s transnational migration and domestic labor. Specifically, it analyzes the Indonesian and Saudi states’ involvement in shaping the migration and working conditions of Indonesian domestic servants employed in Saudi Arabia. It examines key aspects of both states’ direct and indirect influences on the feminization of the migrant labor force, the limitations of their policies for protecting overseas migrant women, and the political strategies that activists are employing to broaden the states’ spaces and scales of jurisdiction. It points up gender-specific limits to the internationalization of state labor regulation, as well as possibilities that NGOs have identified for improving the protection of migrant workers in this transnational context. It thus identifies some particular ways in which contestations around women’s transnational labor migration and gendered constructions of domestic labor are interlinked with the changing geographies of state power.
