Leisure and Consumption
Leisure and consumption have always been intimately linked, in the same way as work and production are. During the industrial Protestant era, consumption and leisure were seen as indulgent, decadent, feminine pursuits not worthy of serious intellectual analysis. One reason for this was that production, commerce, and industry were embodied in the concept of work, emphasized by the dominant culture of the time as central to the development of good character. Consumption, however, was seen as an inconsequential activity engaged in during one's leisure time.

Identity and the commodification of leisure
This paper examines the effect commodifying leisure has on its perceived quality for the individual. We argue that leisure has a great deal to contribute to individual identity in urban industrial society, but that this is being overshadowed in a market economy which commodifies leisure and produces it for a large number of people, with a focus on profit. This idea leads us to examine the conformity and gender stereotyping potentiality of leisure to act as a restrictive rather than a liberalizing influence on identity thus devaluing the experience of leisure. Finally, we suggest that leisure providers can redirect leisure policy to ensure access to leisure outside of a purely commercial realm, a leisure that is potentially self-exploring, self-determining, rather than purchased.
Researches on Structural Factor Involvement in Oral Tribology
This study is focused on two ceramic materials, D.SING (Ivoclar) and VM13 (emphasis the VITA TN), frequently used in restorative dentistry practice and it comes to complete a full set of results obtained by the authors over several years of research on oral tribology with main influence on oral health. In this way there are involved more specific structural aspects of dental restorative ceramic materials quality as is shown in [1].
