Measurement models of women’s autonomy using the 1998/1999 India DHS

Research concerning the relationship between female status and demographic behaviour has largely concluded that community level influences are most important, while status and autonomy at the individual level are far less so. This consensus, however, rests on an untested a priori typology of women’s status and tenuous assumptions about the measurement of defined status dimensions on the individual level. To better understand the potential influences of both community and individual elements it is necessary to take a step back and assess the validity of the constructs of autonomy used. This work uses a latent variable measurement modelling framework to test both the dimensionality of women’s status and the appropriateness of using simple additive index scaling in constructing measures of women’s status on the individual level using questions from the Demographic and Health Surveys status-of-women module in India for 1998/1999.     

Rural Azerbaijan through Quantitative and Qualitative Research Lenses: Debating the Transition to Small Farm Capitalism

This article examines agrarian relations in post‐Soviet Azerbaijan after redistributive land reforms. We argue that the reforms failed to establish small‐farm capitalism on former collective and state farm land. Commodity production in rural Azerbaijan is characterized by increasing concentration of land and capital, and the recipients of the privatized land shares procure livelihoods not through commercial farming, but through a combination of strategies—including wages, remittances from migrant relatives, and subsistence agriculture. This study is based on the combination of state statistics, government reports, and local ethnography—in‐depth interviews with land reform administrators and with rural residents in six diverse villages from two distinct regions of Azerbaijan. Previous studies of post‐Soviet transition in rural Azerbaijan reported different results of the land reforms. A quantitative account based on the state statistics reported a postreform countryside where small farmers, former collective and state laborers, live off their privatized land shares and increase agricultural productivity. A qualitative account based on local ethnography suggested that the privatized land shares play a marginal role in the livelihoods of local residents. We show how the discrepancy is illusory and stems from an erroneous, legal definition of “small farms” used in the state statistics, which conflates socially distinct categories of land use. When the statistical terms are put into their social context, the quantitative data confirm the qualitative findings.     

Visual cryptography on graphs

In this paper, we consider a new visual cryptography scheme that allows for sharing of multiple secret images on graphs: we are given an arbitrary graph (V,E) where every node and every edge are assigned an arbitrary image. Images on the vertices are “public” and images on the edges are “secret”. The problem that we are considering is how to make a construction such that when the encoded images of two adjacent vertices are printed on transparencies and overlapped, the secret image corresponding to the edge is revealed. We define the most stringent security guarantees for this problem (perfect secrecy) and show a general construction for all graphs where the cost (in terms of pixel expansion and contrast of the images) is proportional to the chromatic number of the cube of the underlying graph. For the case of bounded degree graphs, this gives us constant-factor pixel expansion and contrast. This compares favorably to previous works, where pixel expansion and contrast are proportional to the number of images.     

Family Size,Cognitive Outcomes,and Familial Interaction in Stable,Two-Parent Families: United States, 1997–2002

Measures of children’s time use, particularly with parents and siblings, are used to evaluate three hypotheses in relation to the vocabulary and mathematical skills development: (1) the resource dilution hypothesis, which argues that parental and household resources are diluted in larger families; (2) the confluence hypothesis, which suggests that the intellectual milieu of families is lowered with additional children; and (3) the admixture (“no effect”) hypothesis, which suggests that the negative relationship between family size and achievement is an artifact of cross-sectional research resulting from unobserved heterogeneity. Each hypothesis is tested using within-child estimates of change in cognitive scores over time with the addition of new children to families.
