In this paper, we propose a user participation behavior prediction model for social hotspots, based on user behavior and relationship data, to predict user participation behavior and topic development trends. Firstly, for the complex factors of user behavior, three dynamic influence factor functions are defined, including individual, peer and community influence. These functions take timeliness into account using a time discretization method. Secondly, to determine laws of individual behavior and group behavior within a social topic, a hotspot user participation behavior prediction model is proposed and associated with the basic concepts of randora field and Markov property in information diffusion. The experimental results show that the model can not only dynamically predict the individual behavior, but also grasp the development trends of topics.展开更多
One can distinguish three levels in the integrative unity of knowledge and norms （assessments）, which is termed bioethics. The first level is theoretical. It is connected with the facts and truths. The second level ...One can distinguish three levels in the integrative unity of knowledge and norms （assessments）, which is termed bioethics. The first level is theoretical. It is connected with the facts and truths. The second level deals with establishing of certain standards and rules of conduct, with the monitoring of their implementation and the assessment of the results of implementation/violation of norms. The third level is associated with individual behavior, formed on the basis of relevant knowledge （or lack of it, as is evident from the table）, and the rules governing its application. Theoretical Bioethics is an integral part of Philosophy---the practical Bioethics is directly related to Law and applied Bioethics deals with the personal standards of specific behavior in concrete situations. Social need for regulatory control of any activity with living entities has led to rapid development of practical Bioethics, while its philosophical content developed more slowly. This creates a conflict of norms and values, hampering the adoption of individual decisions now in the field of applied Bioethics. Deontologization of Bioethics can lead to the fact that it will lose its philosophical content and become a specific area of Law. This, in turn, leads to the dehumanization of Bioethics. It is therefore necessary to conduct a methodological analysis of the relationship of Philosophy, Bioethics and Law, the results of which will focus the researchers on the synchronization of the axiological, praxeological and ethical components of scientific research in order to preserve the intellectual integrity of Bioethics.展开更多
