From Emotion to Mobilization: Examples of the Confrontation of Human Tragedies in the Social Networks with Images: The Cases of Monique Koumatekel and Blériot Tsanou

To produce emotion, the discourse of social networks tries to confront the reader with social reality. The mediation activity at the heart of any communication activity is hidden. This process is also based on the use of figures to express the unspeakable by the shock of images, which allows the reader to experience emotion but also to push him to act. It is the link between the emotion of an individual targeted by social networks and collective mobilization, which we wish to consider as a means of relaunching the debate and drawing attention to social issues, thus allowing us to rethink sociability with politics.

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.

From Provincialism to Metropolitanism:Social Mobility in English and American Novels of “the Young Man from the Provinces"

基于莱昂内尔·特里林对＂外省青年＂的界定,本文指出再现主人公从小地方向大都市流动是19世纪以来英美小说中反复出现的主题。这种流动或生命之旅不仅仅是生活和职业上地理位置的迁移或变化,它反映的是＂外省青年＂在身体或精神层面向上的社会流动。但在描写这一类似的向上流动的趋势背后,英美小说所揭示出的流动动机和表现却大相径庭,即便在同一国度属于不同历史时期的小说中它们也迥然有别。19世纪中叶的英国小说呈现的是主人公社会实用主义自我教育形式的社会流动,而美国此类小说别具一格地描写的是主人公对美国梦的追寻,更确切地说,是他们的幻灭。19和20世纪之交以来,英美这类小说倾向于再现＂外省青年＂的精神历险。文章最后探讨了这种由小地方向大都市流动的动因和启示。

Reporting and understanding the safety and adverse effect profile of mobile apps for psychosocial interventions: An update

Recent years have seen a rapidly increasing trend towards the delivery of health technology through mobile devices. Smartphones and tablet devices are thus becoming increasingly popular for accessing information and a wide range of services, including health care services. Modern mobile apps can be used for a variety of reasons, ranging from education for the patients and assistance to clinicians to delivery of interventions. Mobile phone apps have also been established to benefit patients in a scope of interventions across numerous medical specialties and treatment modalities. Medical apps have their advantages and disadvantages. It is important that clinicians have access to knowledge to make decisions regarding the use of medical apps on the basis of risk-benefit ratio. Mobile apps that deliver psycho social interventions offer unique challenges and opportunities. A number of reviews have highlighted the potential use of such apps. There is a need to describe, report and study their side effects too. The adverse effects associated with these apps can broadly be divided into:(1) those resulting from the security and safety concerns;(2) those arising from the use of a particular psycho social intervention; and(3) those due to the interaction with digital technology. There is a need to refine and reconsider the safety and adverse effects in this area. The safety profile of a mobile PSI app should describe its safety profile in:(1) privacy and security;(2) adverse effects of psychotherapy; and(3) adverse effects unique to the use of apps and the internet. This is, however, a very new area and further research and reporting is required to inform clinical decision making.

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.

APPOW:An Advanced Routing Protocol Based on Parameters Optimization in the Weighted Mobile Social Network

Due to the increasing number of wireless mobile devices,the possibility of mobile communications without infrastructure becomes a reality.The Decentralized Mobile Social Network(DMSN) is a paradigm where nodes can move freely and organize themselves arbitrarily.Routing in these environments is difficult for the reason of the rapid changes of the social relationship graph's topology.Meanwhile,the social ties among nodes change overtime.Therefore,an efficient data forwarding mechanism should be considered over the temporal weighted relationship graph.In this paper,an Advanced routing Protocol based on Parameters Optimization in the Weighted mobile social network(APPOW) is proposed to improve the delivery success ratio and reduce the cost of exchanging information.APPOW combines the normalized relative weights of three local social metrics,i.e.,LinkRank,similarity and contact strength,to select the next relay node.The weights of the three metrics are derived by pair-wise learning algorithm.The result shows that APPOW outperforms the state-ofthe-art SimBet Routing in delivering message and significantly reduces the average hops.Additionally,the delivery performance of APPOW is close to Epidemic Routing but without message duplications.

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.

Human Capital of Family and Social Mobility in Rural Areas-Evidence from China

This research focuses on the impact of family＇s human capital on social mobility in China＇s rural community.Empirical research is conducted based on data from surveying a typical rural community in the past 20 yr.The study indicates that social mobility in rural area is active in the past 20 yr,and the human capital of family,represented by primary labor＇s education level,has played an essential role in mobility of low social class.Meanwhile,socio-economic development and the change of supply and demand in labor market dims the signaling role of degree education,but the impact of occupational training is increasingly remarkable.Therefore,the change from sole degree education to multi-leveled education including occupational education and training is a main way for China＇s rural families in low class to realize social mobility.

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.

Assessment on self-care, mobility and social function of children with spina bifida in Turkey

The aim of the study was to investigate the functional performance in children with spina bifida, using the Pediatric Evaluation of Disability Inventory （PEDI） to look into capacity of twen- ty-eight children with spina bifida with lesions at different levels in different dimensions of self- care, mobility and social function. Mean age of the patients was 3.5 ± 2.3 （1-10） years. In the muscle test carried out, 13 patients （44.8%） had no movements including pelvic elevation in lower extremity muscles and they were at level 5. Sixteen patients （54%） were non-ambulatory according to the Hoofer ambulation classification. Raw and scale scores in the self-care, mobil- ity and social function domains both in the functional skill scale and in the caregiver scale were found to be lower compared to the data of the normal population. A statistically significant correlation was observed in the self-care values of the Functional Skills Scales and the Caregiver Assistance Scale measurements, which was positive for age and negative for Functional Ambu- lation Scale and muscle test （P 〈 0.05）. A positive relation was found between the Functional Skills Scales-mobility area and age while a negative relation was observed between Functional Ambulation Scale and muscle test （P 〈 0.005）. A negative relation was also found between Care- giver Assistance Scale-mobility and Functional Ambulation Scale and muscle test （P 〈 0.005）. In our study, the functional performance of the children was found to be low. Low-level lesions, encouraging muscular strength and independence in mobility are all very important factors for functional independence.

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.

Clustering Indoor Location Data for Social Distancing and Human Mobility to Combat COVID-19

The world is experiencing the unprecedented time of a pandemic caused by the coronavirus disease(i.e.,COVID-19).As a countermeasure,contact tracing and social distancing are essential to prevent the transmission of the virus,which can be achieved using indoor location analytics.Based on the indoor location analytics,the human mobility on a site can be monitored and planned to minimize human’s contact and enforce social distancing to contain the transmission of COVID-19.Given the indoor location data,the clustering can be applied to cluster spatial data,spatio-temporal data and movement behavior features for proximity detection or contact tracing applications.More specifically,we propose the Coherent Moving Cluster(CMC)algorithm for contact tracing,the density-based clustering(DBScan)algorithm for identification of hotspots and the trajectory clustering(TRACLUS)algorithm for clustering indoor trajectories.The feature extraction mechanism is then developed to extract useful and valuable features that can assist the proposed system to construct the network of users based on the similarity of the movement behaviors of the users.The network of users is used to model an optimization problem to manage the human mobility on a site.The objective function is formulated to minimize the probability of contact between the users and the optimization problem is solved using the proposed effective scheduling solution based on OR-Tools.The simulation results show that the proposed indoor location analytics system outperforms the existing clustering methods by about 30%in terms of accuracy of clustering trajectories.By adopting this system for human mobility management,the count of close contacts among the users within a confined area can be reduced by 80%in the scenario where all users are allowed to access the site.

New Characteristics and Tendencies on Chinese Social Mobility： A Review of the Study on Current Social Mobility of ＂X Second Generation＂

Over the past decade the social structure of China has undergone profound changes. The vertical social mobility between social classes tended to slow down and the social structures and stratification became solidified. Phrases such as "second generation of the rich,""second generation of officials,"and "second generation of the farmers"appeared frequently on the Internet and other media,which to some extent reflect the trend in social structure. However,little research has been conducted to address these issues in recent years.This field is in great need of systematic and authoritative surveys and studies on social fragmentation,marginalization,stratification,and mobility.
