The regulation of family involvement in deinstitutionalization

Conflicting legal, administrative, and professional policies surround family involvement in the deinstitutionalization process. This article addresses these discrepancies and makes recommendations for developing effective and consistent channels of policy among social workers and other helping professionals.     

Mover-Stayer Models for Analyzing Event Nonoccurrence and Event Timing With Time-Dependent Covariates: An Application to An Analysis of Remarriage

This paper introduces a novel extension of mover-stayer models for duration data that allows time-dependent covariates to be used for both a pair of regression equations, one that identifies the determinants of event timing and one that identifies the determinants of the probability of ultimate event nonoccurrence. Existing models intended to distinguish covariate effects on event timing from those on event nonoccurrence cannot use time-dependent covariates in the equation for the probability of ultimate event nonoccurrence. This paper applies the new model to an analysis of remarriage among American women. The analysis generally demonstrates that some covariates effect remarriage timing while others affect the probability of ultimate remarriage nonoccurrence. Some differences in patterns of remarriage between black women and white women are also reported. Theoretical implications of these findings are discussed.     

Measure of Asymmetry for Square Contingency Tables Having Ordered Categories

For the analysis of square contingency tables with nominal categories, Tomizawa and coworkers have considered measures that represent the degree of departure from symmetry. This paper proposes a measure that represents the degree of asymmetry for square contingency tables with ordered categories (instead of those with nominal categories). The measure proposed is expressed using the Cressie–Read power-divergence or Patil–Taillie diversity index, defined for the cumulative probabilities that an observation falls in row (column) category i or below and column (row) category j (> i ) or above. The measure depends on the order of listing the categories. It should be useful for comparing the degree of asymmetry in several tables with ordered categories. The relationship between the measure and the normal distribution is shown.     

A Liang–Zeger Method for Modeling Dyadic Interdependence in the Analysis of Social Networks

This article introduces a modified Liang–Zeger method for the estimation of the variance–covariance matrix of parameter estimates for models of social network data that include variables to characterize dyadic nonindependence. While the pseudolikelihood method has been used recently to estimate parameters for such models, the issue of estimating their standard errors, or the variance–covariance matrix more generally, has been neglected. This article addresses the issue by proposing a method for such estimation and also presents an illustrative application of the method to empirical social network data.     

Maternal employment and food produced at home: evidence from Japanese data

This paper examines whether mothers’ labor supply discourages home production, focusing on food preparation at home in Japanese families. Although empirical studies on home production are usually conducted using time use data, we use data collected by scanners, which cover daily goods purchased by over 10,000 households over 3 years. Based on the composition of daily food expenditures for foods consumed, we measure how many products are made using time-consuming processes at home, and examine if time-consuming home production is discouraged by mothers’ employment away from home. Controlling for unobserved heterogeneity among households using the panel structure of our scanner data, we first show that mothers’ out-of-home employment has a negative effect on home cooking. This effect is shared across economic classes, particularly when mothers work part-time, as compared with non-working mothers. Second, we show that this negative effect is more apparent in the low economic class. Households in this class show a particular decrease in time-consuming home cooking, especially when the mothers work part-time. Third, the smaller negative effect among the higher class can be explained by stronger health-consciousness and aversion to less-healthy products in this class.

The minimum vulnerability problem on specific graph classes

Suppose that each edge e of an undirected graph G is associated with three nonnegative integers \(\mathsf{cost}(e)\), \(\mathsf{vul}(e)\) and \(\mathsf{cap}(e)\), called the cost, vulnerability and capacity of e, respectively. Then, we consider the problem of finding \(k\) paths in G between two prescribed vertices with the minimum total cost; each edge e can be shared without any cost by at most \(\mathsf{vul}(e)\) paths, and can be shared by more than \(\mathsf{vul}(e)\) paths if we pay \(\mathsf{cost}(e)\), but cannot be shared by more than \(\mathsf{cap}(e)\) paths even if we pay the cost for e. This problem generalizes the disjoint path problem, the minimum shared edges problem and the minimum edge cost flow problem for undirected graphs, and it is known to be NP-hard. In this paper, we study the problem from the viewpoint of specific graph classes, and give three results. We first show that the problem is NP-hard even for bipartite outerplanar graphs, 2-trees, graphs with pathwidth two, complete bipartite graphs, and complete graphs. We then give a pseudo-polynomial-time algorithm for bounded treewidth graphs. Finally, we give a fixed-parameter algorithm for chordal graphs when parameterized by the number \(k\) of required paths.
