网络“审丑”泛化对大学生思想行为的影响及对策研究

伴随着互联网技术的迅速发展，网络已经深入到大学生生活的每个角落，在缤纷复杂的网络世界中，形形色色的信息充斥着大学生的视野。当媒体和个人都以不健康的眼光对待网络审丑时，错误的世界观、人生观、价值观、与审美观就可能使大学生难以明辨是与非、美与丑。以丑为美，趋丑避美，长此以往，网络审丑泛化将会给社会公众，尤其是正在成长的大学生造成思想混乱、主流价值观颠覆及社会主流文化形态变异的趋势，应引起我们高度重视，是网络思想政治教育领域迫切需要研究和亟待解决的新问题。

Trust and Sexual Interaction: The Significance of the Internet on the Sex life and Sexual Risk Behaviors Of Gay and Bisexual Men in Spain

ABSTRACT

This study provides an understanding of the significance of the use of the Internet to find sexual partners, its impact on sexual life, and how it is linked to unprotected sex among gay and bisexual men. A grounded approach was used to analyze interviews with 31 men (aged 19 to 46 years) from Madrid, Barcelona, and Bilbao/San Sebastián, Spain. The results reveal that the Internet is impacting the form and style of life of many men, and particularly their experience of sexuality. Many men regard their sexual experiences with casual partners met through the Internet as unsatisfactory or frustrating. The men provided several reasons behind the search for sexual partners via the Internet: Some interviewees sought to channel needs other than the sexual (company, affection, stable partner). Trust and assumptions built into the virtual interaction become a key to understanding why some men have unprotected sex with partners met on the Internet.     

The longitudinal effects of influence of parental attachment and emotion regulation on Internet delinquency in early adolescence

ABSTRACT

The purpose of this study was to identify the longitudinal influence of parental attachment and emotion regulation on changes in Internet delinquency. This study used the Korean Youth Panel Survey (KYPS) data, in which 2,844 school-age children were annually assessed from Grade 4 in 2004 to Grade 8 in 2008 in South Korea. Latent growth models were used to examine developmental trajectories of Internet delinquency, parental attachment, and emotion regulation longitudinally. This study showed that adolescents experience an increase in Internet delinquency over the fourth year and a decline in the fifth year. The initial level of parental monitoring had significant effects on the initial level of emotion regulation. In addition, the initial level of parental attachment was associated with a slower rate of acceleration of Internet delinquency across time. The study findings indicate that parental attachment influences Internet delinquency among Korean adolescents. The practice implications of the findings are discussed in terms of Internet delinquency reduction efforts.     

The School Success Profile Online

SUMMARY

This article provides an overview of the purposes, development, and implementation of the School Success Profile Online (SSP)–a computerized, self-report survey for middle and high school students. The SSP takes advantage of World Wide Web technology and the increasing access of public schools to computers and the Internet to assess students' perceptions of their neighborhoods, schools, peers, and families, as well as their own psychological and physical health and school performance. The individual and group profiles generated by the SSP can help school social workers identify areas of concern, plan their interventions with students, and evaluate the impact of their efforts at the end of interventions.

A Genetic Algorithm for the Weight Setting Problem in OSPF Routing

With the growth of the Internet, Internet Service Providers (ISPs) try to meet the increasing traffic demand with new technology and improved utilization of existing resources. Routing of data packets can affect network utilization. Packets are sent along network paths from source to destination following a protocol. Open Shortest Path First (OSPF) is the most commonly used intra-domain Internet routing protocol (IRP). Traffic flow is routed along shortest paths, splitting flow at nodes with several outgoing links on a shortest path to the destination IP address. Link weights are assigned by the network operator. A path length is the sum of the weights of the links in the path. The OSPF weight setting (OSPFWS) problem seeks a set of weights that optimizes network performance. We study the problem of optimizing OSPF weights, given a set of projected demands, with the objective of minimizing network congestion. The weight assignment problem is NP-hard. We present a genetic algorithm (GA) to solve the OSPFWS problem. We compare our results with the best known and commonly used heuristics for OSPF weight setting, as well as with a lower bound of the optimal multi-commodity flow routing, which is a linear programming relaxation of the OSPFWS problem. Computational experiments are made on the AT&T Worldnet backbone with projected demands, and on twelve instances of synthetic networks.
