In current academic debates, leisure is increasingly defined as a discursive construction originating both from the specific meanings created by individuals, and the institutionalizing processes that legitimate certain experiences and their spatial-temporal conditions as leisure. As a result of social construction and the different social conditions existing at a certain historical moment in different societies, the borders among the various aspects of leisure are becoming more and more blurred; as is the case, for instance, with the borders between leisure and work activities. Such border-crossing is the leitmotif of this book. Although focusing on sociological research, it has in fact a multidisciplinary scope and will appeal to a variety of scholars and students interested in the study of leisure in contemporary society as a fundamental dimension of everyday sociality and sociability with very important effects on social cohesion as a whole. After an introductory section, offering general frames on key definitions of leisure and leisure issues, five other sections follow which concentrate on more specific aspects of leisure practices and forms in contemporary society.
