This study paper investigates the relation between women and men's life stages in Denmark, and their time allocation in paid work, household work, childcare, and leisure time, and, in particular, how this allocation changes when moving from one stage to another stage. The study uses a new Danish panel dataset merged with Danish administrative register data, which allows for analyzing the impact of individual endogenous characteristics of the respondents, such as preferences for doing specific activities. It has been found that the labor supply of fathers of preschool children is not different from that of young men without children, while there is a negative correlation between mothers of preschool children and young women's labor supply. In comparing fathers and mothers of school children with those of preschool children, the study finds a positive correlation in both genders' labor supply. However, fixed effects estimations do not result in a reduction in mothers, nor in fathers, to preschool children's labor supply, indicating that there are some inborn characteristics for the other life-stage changes, which are not revealed by doing ordinary cross-sectional analyses.
Facility location applications are concerned with the location of one or more facilities in a way that optimizes a certain objective such as mini- mizing transportation cost, providing equitable service to customers, cap- turing the largest market share, etc. Facility location problems give rise to challenging geometrical and combinatorial problems. The research on facility location problems spans many research fields such as operations re- search/management science, industrial engineering, geography, economics, computer science, mathematics, marketing, electrical engineering, urban planning, and related fields. Applications to facility location models abound. Location of warehouses, plants, hospitals, retail outlets are classical examples. Applications are also found in the location of electronical components, warning sirens, sprinklers, radar beams, exploratory oil wells. These are less obvious "facilities". One should consider applying a location model to any scenario that involves finding a best location (or locations) for any object(s). This book Facility Location: A Survey of Applications and Methods pro- vides a state of the art review along with references to important contem- porary topics in locational analysis. The book includes twenty chapters divided into four parts, each dealing with a different aspect of location modeling and implementation. The book concludes with over 1,200 refer- ences. The first part Methodology and Analysis consists of a survey of method- ological and technical aspects of location analysis. Issues such as estimating distances, the error introduced by assuming discrete demand rather than continuous one, global optimization techniques, inference of weights, con- jugate duality, and using Voronoi diagrams are reviewed.
It seems like the summer of dreams come true for Hollywood princess Kaitlin Burke: the media loves her (again), super-cute and funny Austin Meyers is finally her boyfriend and she's starring in a film by her all-time favourite director Hutch Adams.
