Contrary to the healthy parental involvement, a family can also have negative effects on an athlete development. The purpose of this study was to determine gender, father involvement, and mother involvement differences in the psychological profiles of collegiate freshmen athletes as measured by perfectionism, physical self-concept, and psychological well-being. Methods： Eighty-two male and 73 female collegiate freshmen responded to self-reported measures of family involvement, perfectionism, physical self-concept, and psychological well-being. Three separate 2 x 2 x 2 （gender x mother involvement x father involvement） factorial multivariate analysis of variance （MANOVAs） were carried out on the respective subscales from the reported measures. Results： There were significant differences for gender as well as father involvement in perfectionism （p 〈 0.01）. Freshmen females had lower concern over mistakes, and greater levels of organization as well as planfulness than males.

The ＂faith＂ expresses a belief in the capacity of government to concentrate all the power and resources upon the project of human improvement and perfection, while the ＂scepticism＂ is the politics of the powerless in which government cannot produce perfection and enjoys only limited opportunity of directing the activities of its subjects. The aim of this article is to revise Oakeshott＇s distinction in order to apply it to the discussion on inequalities affecting Europe. This discussion held by Chantal Mouffe, Ulrich Beck and Anthony Giddens focused on issues such as： modern patterns of inequality, the coexistence of different ethnic, religious and political forms of life, ＂legitimization＂ of social inequalities, the institutionalization of norms of equality, the problem of recognition, the common identity and so on. The key question is： How the values of equality and justice are best realized in the structure of modern society？ To answer this question, it is necessary not only to assess critilically the authority of governments, but also to examine possible ways of development of the idea of liberal democracy and power relations in contemporary political socidtts. What is our perspective on the way to solve these problems--the reinvention of politics or democratizing democracy？ Even if this research will not help us to find the best political project, however we may be less often cheated in this discussion by irrelevant and ambiguous arguments.展开更多
