An Analysis of the Role of Higher Education Opportunity Expansion in Social Stratification

With higher education entering the public’s vision,the expansion of higher education opportunities has gradually become a hot topic.The lower class is eager to achieve class mobility through this opportunity,while the upper class firmly grasps the few high-quality places in higher education.What role will the expansion of higher education opportunities plays in the overall social stratification?This paper discusses the impact of the expansion of higher education opportunities on social stratification from the upper class and the lower class.

Recommending Friends Instantly in Location-based Mobile Social Networks

Differently from the general online social network(OSN),locationbased mobile social network(LMSN),which seamlessly integrates mobile computing and social computing technologies,has unique characteristics of temporal,spatial and social correlation.Recommending friends instantly based on current location of users in the real world has become increasingly popular in LMSN.However,the existing friend recommendation methods based on topological structures of a social network or non-topological information such as similar user profiles cannot well address the instant making friends in the real world.In this article,we analyze users' check-in behavior in a real LMSN site named Gowalla.According to this analysis,we present an approach of recommending friends instantly for LMSN users by considering the real-time physical location proximity,offline behavior similarity and friendship network information in the virtual community simultaneously.This approach effectively bridges the gap between the offline behavior of users in the real world and online friendship network information in the virtual community.Finally,we use the real user check-in dataset of Gowalla to verify the effectiveness of our approach.

Community Discovery with Location-Interaction Disparity in Mobile Social Networks

With the fast-growth of mobile social network, people＇ s interactions are frequently marked with location information, such as longitude and latitude of visited base station. This boom of data has led to considerable interest in research fields such as user behavior mining, trajectory discovery and social demographics. However, there is little research on community discovery in mobile social networks, and this is the problem this work tackles with. In this work, we take advantage of one simple property that people in different locations often belong to different social circles in order to discover communities in these networks. Based on this property, which we referred to as Location-lnteraction Disparity （LID）, we proposed a state network and then define a quality function evaluating community detection results. We also propose a hybrid community- detection algorithm using LID tor discovering location-based communities effectively and efficiently. Experiments on synthesis networks show that this algorithm can run effectively in time and discover communities with high precision. In realworld networks, the method reveals people＇s different social circles in different places with high efficiency.

Seed Selection for Data Offloading Based on Social and Interest Graphs

The explosive growth of mobile data demand is becoming an increasing burden on current cellular network.To address this issue,we propose a solution of opportunistic data offloading for alleviating overloaded cellular traffic.The principle behind it is to select a few important users as seeds for data sharing.The three critical steps are detailed as follows.We first explore individual interests of users by the construction of user profiles,on which an interest graph is built by Gaussian graphical modeling.We then apply the extreme value theory to threshold the encounter duration of user pairs.So,a contact graph is generated to indicate the social relationships of users.Moreover,a contact-interest graph is developed on the basis of the social ties and individual interests of users.Corresponding on different graphs,three strategies are finally proposed for seed selection in an aim to maximize overloaded cellular data.We evaluate the performance of our algorithms by the trace data of real-word mobility.It demonstrates the effectiveness of the strategy of taking social relationships and individual interests into account.

Research on the Association of Mobile Social Network Users Privacy Information Based on Big Data Analysis

The issue of privacy protection for mobile social networks is a frontier topic in the field of social network applications.The existing researches on user privacy protection in mobile social network mainly focus on privacy preserving data publishing and access control.There is little research on the association of user privacy information,so it is not easy to design personalized privacy protection strategy,but also increase the complexity of user privacy settings.Therefore,this paper concentrates on the association of user privacy information taking big data analysis tools,so as to provide data support for personalized privacy protection strategy design.

Fractal Analysis of Mobile Social Networks

Fractal and self similarity of complex networks have attracted much attention in recent years. The fractal dimension is a useful method to describe the fractal property of networks. However, the fractal features of mobile social networks （MSNs） are inadequately investigated. In this work, a box-covering method based on the ratio of excluded mass to closeness centrality is presented to investigate the fractal feature of MSNs. Using this method, we find that some MSNs are fractal at different time intervals. Our simulation results indicate that the proposed method is available for analyzing the fractal property of MSNs.

Communication for Social Mobilization： An Evaluative Study of the National Immunization Campaign in Nigeria

This study critically evaluates the communication strategies used in the campaign for social mobilization for the National Programme on Immunization in Nigeria. Its objective is to determine the communication factors that contributed to the participation of individuals and groups in the programme at the federal, state, and local government levels. Fifty four subjects, consisting of five policy and decision makers in health, information, and education sectors, five community leaders, 15 media personnel, 15 state health officials, 20 LGA officials, 12 representatives of non-governmental organizations, five opinion leaders, seven clinic staff, six state health officials, and eight mothers were purposively selected from the federal level and two states; Imo and Kano states of Nigeria. Methodology used for data collection includes individual and group interviews and critical evaluation instruments. Findings show that the mass campaign strategy proved to be the most effective strategy for reaching both rural and urban dwellers and specific groups with immunization messages. The alliance between the health workers and community leaders, social groups, NGOs and the information education sectors, had a multiplier effect on the campaign and helped to create feelings of solidarity. The ubiquitous channels of traditional and religious leaders and youth groups helped to spread immunization messages and gain support for the programme. Women and women groups were adequately involved at the federal level and in Imo State, a Christian state in the South-East. This was not the case in Kano State, a Muslim state in the north due to sociocuitural factors. The sustainability of the programme lies in more integration, more intersectoral collaboration, more institutionalization, more quality verification, more decentralization, greater local political commitment, and a multistrategic approach to campaign planning and implementation.

Subjective Social Status,Income Inequality and Subjective Perceptions of Mobility(2003-2013)

Using a sample of over 90,000 urban and rura1 residents from the Chinese Social Survey(CSS)and China Genera1 Social Survey(CGSS)from 2003 to 2013,we analyzed the structural features and influencing factors underlying subjective social status in China.Our findings indicate that over these years,such identification has consistently assumed the shape of a bowling pin:those who“identify with a low social status”account for more than half of respondents,a much higher proportion than in most countries.At the individual level,the net effect on subjective social status of such objective indicators as education,income and occupation has been relatively small,and lessened over the ten years.The correlation between subjective perceptions of mobility and subjective social status is quite strong,but the upward impetus provided by perceptions of upward mobility weakened over the period.At the macro-level,the tempo of economic growth failed to raise the level of class identification,and income inequality had a markedly negative effect.Our research findings further demonstrate that curbing the income gap and increasing opportunities for mobility are important for raising the level of class identification during the transition period.

The Equality–Inequality Dialectics

The assay argues that the Equality-Inequality dialectics is a very complex issue,which reflects many social dilemmas.On one side are the state official commitments to secure,maintain and protect all kinds of formal equalities.On the other side are the natural and genetic distinctions that differ between human-beings while creating and maintaining inequality.In fact,this is kind of a contradiction exists in many fields of social sciences.The essay’s author reviews some of the relevant historical events,such as social mobility,individualism and education and points out on future solutions.Among the proposed suggestions are:1)Embracing Frankl’s giving“Meaning to Life”as a leverage for increasing pleasure of life;2)Recognizing and promoting Creative Individualism as the legitimized ground for inequality;3)Increasing Social Cohesion,required for social empowerment and attaining security and happiness.

Educational Inequality： An Impediment to True Democracy in the United States

Many people believe that democracy is something that can lead everyone toward a better nation and a free and fair society. In 1954, Brown v. Board of Education fundamentally changed the education system in the United States and was a turning point in the evolution of U,S. democracy that made the beautiful American dream available for each individual. However, six decades later, the debate over educational inequality continues. People are still fighting for their equality and well-being. Along with dramatically influential political, economic, and social factors in the United States, educational inequality destroys the commitment of this democratic nation to offer equal opportunity, care, and social justice to younger members of the community. This paper discusses the current problem of educational inequality as it relates to racial and socioeconomic discrimination in urban schools. The aim of this study is to explore knowledge of inequality in the U.S. school system and to raise social and educational awareness to help American children to have equal chances in education and to achieve future success.

Epidemic-Like Proximity-Based Traffic Offloading

Cellular networks are overloaded due to the mobile traffic surge,and mobile social networks(MSNets) can be leveraged for traffic offloading.In this paper,we study the issue of choosing seed users for maximizing the mobile traffic offloaded from cellular networks.We introduce a gossip-style social cascade(GSC) model to model the epidemic-like information diffusion process in MSNets.For static-case and mobile-case networks,we establish an equivalent view and a temporal mapping of the information diffusion process,respectively.We further prove the submodularity in the information diffusion and propose a greedy algorithm to choose the seed users for traffic offloading,yielding a sub-optimal solution to the NP-hard traffic offloading maximization(TOM) problem.Experiments are carried out to study the offloading performance,illustrating that the greedy algorithm significantly outperforms the heuristic and random algorithms,and user mobility can help further reduce cellular load.
