Three competing hypotheses are tested regarding determinants of husband"s (vs. wife"s) participation in 12 selected household/child-care activities. The research utilizes interview responses of husbands, although it compares responses of both husbands and wives in a proportionate stratified area-probability sample from adjacent midwestern cities. The socialization-ideology hypothesis receives the strongest, albeit modest, support of the three hypotheses. Only marginal support is found for the relative husband/wife resources hypothesis, emphasizing professional employment of wives. No support is found for the time-availability hypothesis. Implications for the further integration of work and family roles for men are considered.

Recently, in Mathematical and computational Applications Journal chiu et al. [1] and chen and chiu [2] propose an inventory model based on EPQ with rework to determine the replenishment lot size and the number of shipments for a vendor-buyer integrated production-inventory system. They solve the inventory problem by considering both variables as continuous. However, the number of shipments must be considered as discrete variable. In this direction, this paper revisits and solves the inventory problem of [1-2] considering the decision variables according to their nature. Two easy and improved algorithms are proposed which simplify and complement the research works of [1-2].
The paper presents a new algorithm for the analysis of the kinematic singularities for different parallel structures using a testing stand. The derived expressions are used to superimpose graphical representations of ...

Total plant leaf area of individual maize plants ( Zea mays L.) at anthesis was estimated by multiplying the area of leaf number seven, the best estimator in these studies based on correlation analyses, by an appropriate “leaf area factor.” This factor was determined by dividing total plant leaf area by the area of leaf seven, which was the largest or nearly the largest leaf for the 23 genotypes studied. For precise estimation, a factor should be determined for the largest leaf of each genotype or treatment in each population and each year. A very close correlation between estimated and actual leaf areas was observed when the leaf area factor was used. To minimize the error incurred by plant-to-plant variation, at least five plants should be completely measured to determine the leaf area factor for a given genotype. This method of estimation could be applied widely to leaf area measurements in maize and should make it possible to determine leaf areas in yield trials, breeding nurseries, and extensive field tests.
