Instead of extreme curves (mappings of a segment to a manifold) we investigate extreme networks, which are mappings of graphs (one-dimensional cell complexes) to a manifold. Various applications of the approach are presented, such as several generalizations of the famous Steiner problem of finding the shortest network spanning given points of the plane.

The advantage of SWB data lies in the accessibility to rich information regarding perceptions, attitudes, and behaviors. With this advantage, the book inquires into the perceptions toward family and work and explores the attitudes that lead to low fertility in the region. To this end, first a comparative analysis with international cross-sectional data is performed and the East Asian characteristics of family and work perceptions are documented. Then, three democracies in the region are focused on—Japan, South Korea, and Taiwan—to investigate the relationships between cultural orientations, work–life balance, and fertility outcomes with panel data. In addition, East Asian results are compared with those in India, which has also been experiencing a rapid transition from a traditional society to an industrial one. The results support the idea that the friction between persistent gender-based role divisions and socioeconomic transformation in East Asia makes it difficult for women to balance family and work, prompting fertility decline to the lowest-low level in the region.Population Studies of Japan,2198-2732SociologySocial groupsDemographyIndustrial sociologySexSociology of Family, Youth and AgingApplied DemographySociology of WorkGender StudiesSociology.Social groups.Demography.Industrial sociology.Sex.Sociology of Family, Youth and Aging.Applied Demography.Sociology of Work.Gender Studies.306.36095Kageyama Junji1425274Teramura Eriko1425275MiAaPQMiAaPQMiAaPQBOOK9910742494003321Perception of Family and Work in Low-Fertility East Asia3555491UNINA
