This is because both the two Scientific Approaches previously mentioned have not the property of “the perfect induction”. Consequently, although they can even reach an experimental confirmation of the theoretical results, and thus a “valid description” of the various phenomena of the surrounding world, such a description has not an “absolute value”. In fact, it always and only has an “operative validity”, that is, it exclusively and solely refers to an “experimental point of view”. This means that such an “operative validity” cannot represent the basis for a logical process characterized by a “perfect induction”. In addition, the Traditional Scientific Approach is also characterized by “Insoluble” Problems, “Intractable Problems”, Problems with “drifts”, which could generally be termed as “side effects”. On the other hand, the same com-possible Scientific Approach based on the Emerging Quality of Self-Organizing Systems, also presents its “Emerging Exits”. Consequently, none of the two mentioned scientific Approaches has the “gift” of “the perfect induction”. However, there are significant differences between the two. Differences that may “suggest” the most appropriate choice among them for an “operative point of view”. This conclusion will be com-proved by considering, with particular reference, both the “side effects”, which are related to the Traditional Approach and, on the other hand, the “Emerging Exits”, which specifically pertain to the new Scientific Approach based on the Emerging Quality of Self-Organizing Systems.展开更多

It is a well-established proposition in portfolio theory that whenever there is an imperfect correlation between returns risk is reduced by maintaining only a portion of wealth in any asset, or by selecting a portfolio according to expected returns and correlations between returns. The major improvement of the portfolio approaches over prior received theory is the incorporation of 1) the riskiness of an asset and 2) the addition from investing in any asset. The theme of this paper is to discuss how to propose a new mathematical model like that provided by Markowitz, which helps in choosing a nearly perfect portfolio and an efficient input/output. Besides applying this model to reality, the researcher uses game theory, stochastic and linear programming to provide the model proposed and then uses this model to select a perfect portfolio in the Cairo Stock Exchange. The results are fruitful and the researcher considers this model a new contribution to previous models.展开更多

Moreover,the rocking curves of PyS-KDP suggest that CSB-6B can deteriorate the structural perfection of PyS-KDP.展开更多

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

In 2012,the system was amended and perfected again by the Criminal Procedure Law and its interpretations. However,compared with the criminal defense system,evidence system and coercive measure system,the amendment of criminal suit incidental civil action system has not drawn enough attention.At the core of 2012 new Criminal Procedure Law 's amendment to the criminal suit incidental civil action system,this paper tries to conclude the development path of this system.And the author gives some advice in this paper to further improve the system so that the academics will pay more attention to this system and research it deeply.展开更多
