Maternal care receptivity--an innovative approach for the evaluation of MCH services

Despite rapid expansion in the maternal and child health and family planning services, there have been few attempts made to study the extent of utilisation of these services and their impact. The present study reports a simple method evolved in the quantification of utilisation of maternal care services (called maternal care receptivity - MCR), the relationship of factors such as age, parity, caste of the women and the distance of the health centre on the MCR and the impact of MCR on perinatal and neonatal mortalities. An inverse relationship was observed between MCR and perinatal and neonatal mortality rates and the two rates were three times less among babies born to mothers with high MCR scores compared to those with poor MCR scores.     

Special education disproportionality in the United States,Germany, Kenya,and India

Disproportionality in special education includes the underrepresentation and overrepresentation of children by gender, economic status, race, ethnicity, language, and culture. This article reviews literature on disproportionality in the United States, Germany, Kenya, and India. Societal views of disability, classism, racism, and inequitable assessment are among the factors that contribute to disproportionality. Preventative medicine, equitable access to resources, ethical and effective assessment procedures, and educational practices that are gender equitable and culturally responsive may reduce the problem of disproportionality.     

Does “buyer beware” work in migration? Contracting between brokers and migrants in Vietnam

This article is an attempt to open the lid a little of the “black box of migration” i.e. brokers. Analysing contracts between brokers and labour migrants, we identify four different forms of exploitation of migrants by brokers: expropriation of skill premium, risk shifting, over‐charging, and non‐refund of deposits. Opportunistic behaviour by brokers, as evidenced by such exploitation, is seen as a market failure that is explained by human attributes and transactional characteristics. Given the rigidities in the human attributes of the contracting parties and the nature of migration as a risky multi‐period transaction, proposals are made for non‐market interventions, which can lead to more equitable contracting.

Estimation of Error and Bias in Bayesian Monte Carlo Decision Analysis Using the Bootstrap

Bayesian Monte Carlo (BMC) decision analysis adopts a sampling procedure to estimate likelihoods and distributions of outcomes, and then uses that information to calculate the expected performance of alternative strategies, the value of information, and the value of including uncertainty. These decision analysis outputs are therefore subject to sample error. The standard error of each estimate and its bias, if any, can be estimated by the bootstrap procedure. The bootstrap operates by resampling (with replacement) from the original BMC sample, and redoing the decision analysis. Repeating this procedure yields a distribution of decision analysis outputs. The bootstrap approach to estimating the effect of sample error upon BMC analysis is illustrated with a simple value-of-information calculation along with an analysis of a proposed control structure for Lake Erie. The examples show that the outputs of BMC decision analysis can have high levels of sample error and bias.     

Underground Markets as Fields in Transition: Sex Work in New York City

Most ethnographers visualize their fieldwork study vis‐à‐vis their long‐term commitment to a bounded sociospatial context—an “ecology.” In this manner, the majority of ethnographic studies are presented as studies not only of practices but also of recognizable physical ecologies that breathe life into the practices—for example, homes, ghettos, firms, schools, and so on. In the pages that follow, I consider the ways in which the status of place has shifted in urban sex work. The shifting commerce of sexual services in New York enables me to open up a set of methodological issues about the role of space in ethnographic work. One in particular is at the core of this paper: namely, because so many ethnographic labors begin with the selection of a field site, what conceptual issues arise that fieldworkers must pay attention to vis‐à‐vis that decision? For example, the field site may change, the field site may itself be shaped by wider societal forces, and it may be simply dissolve over time. How does any of this impact a technique that is premised on the dependability of “sitting” so that others may be dependably followed? I draw on the notion of “strategic action fields” to present an alternative analytic framework, one more useful for the challenges ethnographers face.     

Problem Gambling Among International and Domestic University Students in Australia: Who is at Risk?

Young people are a high risk group for gambling problems and university (college) students fall into that category. Given the high accessibility of gambling in Australia and its association with entertainment, students from overseas countries, particularly those where gambling is restricted or illegal, may be particularly vulnerable. This study examines problem gambling and its correlates among international and domestic university students using a sample of 836 domestic students (286 males; 546 females); and 764 international students (369 males; 396 females) at three Australian universities. Our findings indicate that although most students gamble infrequently, around 5 % of students are problem gamblers, a proportion higher than that in the general adult population. Popular gambling choices include games known to be associated with risk (cards, horse races, sports betting, casino games, and gaming machines) as well as lotto/scratch tickets. Males are more likely to be problem gamblers than females, and almost 10 % of male international students could be classified as problem gamblers. Hierarchical regression analysis showed that male gender, international student status, financial stress, negative affect and frequency of gambling on sports, horses/dogs, table games, casino gaming machines, internet casino games and bingo all significantly predicted problem gambling. Results from this study could inform gambling-education programs in universities as they indicate which groups are more vulnerable and specify which games pose more risk of problem gambling.     

FPT algorithms for Connected Feedback Vertex Set

We study the recently introduced Connected Feedback Vertex Set (CFVS) problem from the view-point of parameterized algorithms. CFVS is the connected variant of the classical Feedback Vertex Set problem and is defined as follows: given a graph G=(V,E) and an integer k, decide whether there exists F?V, |F|??k, such that G[V?F] is a forest and G[F] is connected. We show that Connected Feedback Vertex Set can be solved in time O(2 ^O(k) n ^O(1)) on general graphs and in time $O(2^{O(\sqrt{k}\log k)}n^{O(1)})$ on graphs excluding a fixed graph H as a minor. Our result on general undirected graphs uses, as a subroutine, a parameterized algorithm for Group Steiner Tree, a well studied variant of Steiner Tree. We find the algorithm for Group Steiner Tree of independent interest and believe that it could be useful for obtaining parameterized algorithms for other connectivity problems.
