Social capital and uptake of primary healthcare during protracted displacement
The world's refugee populations primarily reside in low- and middle-income countries, where they face protracted displacement and limited financial and human capital. Social capital is among the few assets they can leverage for resilience. Despite its importance, few studies have examined how social capital influences the uptake of healthcare services during protracted displacement. This study examines the associations of refugee with access to m…
Prevalence, locations and predictors of attitudes accepting both intimate partner violence and additional forms of violence against women and girls in South Sudan
Most research on violence against women and girls (VAWG) in South Sudan has focused on intimate partner violence (IPV) neglecting other forms of VAWG. This research aims to determine the prevalence of attitudes accepting IPV and whether it overlaps with attitudes accepting additional forms of VAWG (child marriage, raiding villages for women during cattle rustling or other raids or female genital mutilation) in South Sudanese men and women, or are…
How to estimate health service coverage in 58 districts of Benin with no survey data
The global movement to use routine information for managing health systems to achieve the Sustainable Development Goals, relies on administrative data which have inherent biases when used to estimate coverage with health services. Health policies and interventions planned with incorrect information can have detrimental impacts on communities. Statistical inferences using administrative data can be improved when they are combined with random proba…
Difference in HIV prevalence by testing venue
Growing demand for use of Health Facility (HF) HIV testing data, in addition to other testing data to obtain district level HIV prevalence requires understanding the comparability of these various sources. We analysed the 2011 Uganda AIDS indicator survey data to assess: the proportion of people tested for HIV across Uganda by venue of testing; HIV prevalence ratio for those tested in a HF compared to those tested in community setting; [Katz, D.,…
Is development aid to strengthen health systems during protracted conflict a useful investment? The case of South Sudan, 2011–2015
Introduction: Is achievement of Sustainable Development Goal (SDG) 16 (building peaceful societies) a precondition for achieving SDG 3 (health and well-being in all societies, including conflict-affected countries)? Do health system investments in conflict-affected countries waste resources or benefit the public's health? To answer these questions, we examine the maternal, newborn, child and reproductive health (MNCRH) service provision during pr…
Combining national survey with facility-based HIV testing data to obtain more accurate estimate of HIV prevalence in districts in Uganda
Facility data can be combined with population survey data to obtain more accurate HIV prevalence estimates for geographical areas with small population survey sample sizes. We recommend use of the methodology by district level managers to obtain more accurate HIV prevalence estimates to guide decision making without incurring additional data collection costs
Population-level effective coverage of adolescent weekly iron and folic acid supplementation is low in rural West Bengal, India
Objective: To assess the coverage of the adolescent weekly iron and folic acid supplementation (WIFS) programme in rural West Bengal, India. Design: We conducted a population-based cross-sectional survey of intended WIFS programme beneficiaries (in-school adolescent girls and boys and out-of-school adolescent girls).

Measuring health system resilience in a highly fragile nation during protracted conflict
Health systems resilience (HSR) is defined as the ability of a health system to continue providing normal services in response to a crisis, making it a critical concept for analysis of health systems in fragile and conflict-affected settings (FCAS). However, no consensus for this definition exists and even less about how to measure HSR. We examine three current HSR definitions (maintaining function, improving function and achieving health system …
Are health workers reduced to being drug dispensers of antiretroviral treatment? A randomized cross-sectional assessment of the quality of health care for HIV patients in northern Uganda
High quality of care (QoC) for antiretroviral treatment (ART) is essential to prevent treatment failure. Uganda, as many sub-Saharan African countries, increased access to ART by decentralizing provision to districts. However, little is known whether this rapid scale-up maintained high-quality clinical services. We assess the quality of ART in the Acholi and Lango sub-regions of northern Uganda to identify whether the technical quality of critica…
Using lot quality assurance sampling to assess access to water, sanitation and hygiene services in a refugee camp setting in South Sudan
This study, one of the few adaptations of LQAS for a camp setting, shows that it is a feasible method for regular monitoring, with the added value of enabling camp managers to identify and advocate for the least served areas within the camp. Feedback on the results from stakeholders was overwhelmingly positive
Institutionalizing and sustaining social change in health systems
The key to high impact health services is institutionalizing and sustaining programme evaluation. Uganda represents a success story in the use of a specific programme evaluation method: Lot Quality Assurance Sampling (LQAS). Institutionalization is defined by two C's: competent programme evaluators and control mechanisms that effectively use evaluation data to improve health services. Sustainability means continued training and funding for the ev…
Empowering districts to target priorities for improving child health service in Uganda using change management and rapid assessment methods
BACKGROUND: Local health system managers in low- and middle-income countries have the responsibility to set health priorities and allocate resources accordingly. Although tools exist to aid this process, they are not widely applied for various reasons including non-availability, poor knowledge of the tools, and poor adaptability into the local context. In Uganda, delivery of basic services is devolved to the District Local Governments through the…
Associations with HIV testing in Uganda
Beginning in 2003, Uganda used Lot Quality Assurance Sampling (LQAS) to assist district managers collect and use data to improve their human immunodeficiency virus (HIV)/AIDS program. Uganda's LQAS-database (2003-2012) covers up to 73 of 112 districts. Our multidistrict analysis of the LQAS data-set at 2003-2004 and 2012 examined gender variation among adults who ever tested for HIV over time, and attributes associated with testing. Conditional l…
Can health workers reliably assess their own work? A test–retest study of bias among data collectors conducting a Lot Quality Assurance Sampling survey in Uganda
BACKGROUND: Lot Quality Assurance Sampling (LQAS) is a classification method that enables local health staff to assess health programmes for which they are responsible. While LQAS has been favourably reviewed by the World Bank and World Health Organization (WHO), questions remain about whether using local health staff as data collectors can lead to biased data. METHODS: In this test-retest research, Pallisa Health District in Uganda is subdivided…
Improving the collection of knowledge, attitude and practice data with community surveys
BACKGROUND: Second-stage sampling techniques, including spatial segmentation, are widely used in community health surveys when reliable household sampling frames are not available. In India, an unresearched technique for household selection is used in eight states, which samples the house with the last marriage or birth as the starting point. Users question whether this last-birth or last-marriage (LBLM) approach introduces bias affecting survey …

Maternal recall error of child vaccination status in a developing nation
In the absence of vaccination card data, Expanded Program on Immunization (EPI) managers sometimes ask mothers for their children's vaccination histories. The magnitude of maternal recall error and its potential impact on public health policy has not been investigated. In this study of 1171 Costa Rican mothers, we compare mothers' recall with vaccination card data for their children younger than 3 years. Analyses of vaccination coverage distribut…
Supervision of primary health care in Costa Rica
A time-use survey of rural health supervisors (RHSs) and nurse supervisors (NSs) in Costa Rica's primary health care system was carried out to determine whether recently discovered deficiencies in primary health care delivery could be due to inadequate supervision of community health workers (CHWs). The supervisors' recall of their time use in the previous month's work was the basis for the study. Limitations of this type of data are discussed. I…

Argues that man creates a cultural order inside which he lives. Outside of that form of life is the 'wilderness': the outer wilderness of untamed nature and the inner psychological wilderness of areas of personality hidden in everyday life.

Only by experiencing the wilderness outside our normal system of living can we understand what we are as civilised beings within our f…
On the Ambiguities of A Sociological Analysis of the Culture of Narcissism
This article is devoted to an analysis of three sets of ambiguities underlying sociological analyses of the new culture of narcissism. The first set concerns the differential importance of childhood experiences and the contradictory cultural norms that regulate the placement of the adult self in time and space. The second set concerns the problem of whether these contradictions result from the structural characteristics of post-industrial societi…

Household Work as an Ordeal
Some feminist authors assert that household work is inexorably debasing for women. This paper questions that hypothesis on both theoretical and methodological grounds by exploring (a) ambiguities in the links between patriarchy and capitalism and (b) the meanings of housework across cultural and historical settings. A research agenda is proposed in which it is suggested that housework is both an ordeal of civility through which individuals judge …
