The SP can help us to analyze the information spreading performance and research the latent relationship in the weighted social network, and so on. As the size of the social network increases, the traditional SP algorithms have poor performance and there is not a suitable algorithm for weighted social network. Some features of the network analysis are beneficial to solve this problem, and community structure ignored by the traditional methods is one of the most important features. In this paper, we propose a shortest path algorithm based on community detection （SPCD） by integrating community detection algorithm with traditional search methods. SPCD constructs a community graph by using community structure to narrow the searching scope. The algorithm presented improves the time efficiency and maintains the accuracy scale of the SR Experimental results on five real-world networks demonstrate the effectiveness of the proposed methods for the SP problem.展开更多

The objective of this study is to identify the relationship between the rate of suicide in contemporary society and how it can be affected by the way of suicide reporting at the same time. Qualitative method is used to analysis the data capturing from observation, interviews and textual analysis. Special attention has been paid to the news reporting in the suicide in Sri Lankan newspapers. Sinhala medium newspapers： Lankadeepa, Diwaina, Lakbima, Silumina, Dinamina, Rivira, were used as the major sample of this study. Time period is located from January 2000 to January 2010. In conclusion, Suicide has been reporting in Sri Lanka as a heroic and sensational action for the target of maximum selling and the financial benefit of media institutions. Use of Language in suicide reporting and the placement of the story in the newspaper have been two major factors that cause to glamorize the incident. Suicide reporting is highly sensational and rhetorically made by the ownership of the media and non-ethical consideration of the journalism in Sri Lanka. Victims and vulnerable are encouraged to get in to suicide and they are generally encouraged to their action for faith. Suicide should be reported in the newspaper as a problem of mental health and attention should be drawn to well inform the public on the issue. Human incidents should not be reported in media for cheap commercial purposes that indirectly chance to gain much financial profit through the highest selling and expansion. This study suggest to take necessary action to immediately make a frame of ethics of media reporting that avoids such unethical reporting in the practice of suicide reporting in Sri Lanka.展开更多

On this basis, teachers developed a systematical thinking method, perspective and way of act. Currently, teachers arrange seats and interact with students and do many other things according to their score sub-consciously. This phenomenon, however, has a long-standing basis on which the school evaluates teachers and teachers evaluate themselves.展开更多
