Effects of outdoor shared spaces on social interaction in a housing estate in Algeria

This study aims to identify how the characteristics of shared outdoor spaces in housing estates influence residents to interact with one another. The study specificalty focuses on a housing project catted la cite des 1000 logts, which is situated in a zone d＇habitat urbaine nouvelle in Biskra, a city in South Algeria. The investigation draws on two sources of information, observations of the ways in which the residents use their neighborhood spaces and a questionnaire survey with residents about the perceived adequacy of these spaces for social interaction. Data for the survey was collected from the owners of fiats in the apartment blocks surrounding the open spaces. Housing samples were taken from a total of 1000 housing units identified within the study area. Twenty five percent （25%） of the total housing units were selected. Out of the 250 questionnaires administered to household-heads who were the respondents, only 230 were subsecluently retrieved for data anatysis. Results showed that the high degree of ＂openness＂ of la cite des 1000 logts and the poor quatity of communal outdoor spaces in the area discourage art forms of spatial use and reduce these outdoor spaces to transit areas. Furthermore, findings indicated that the layout of buildings and the quality of common outdoor spaces in residential neighborhoods substantially affect the use of these spaces and the social interaction among residents.

Research on the Renewal Strategy of Social Space for the Elderly in Colleges and Universities from the Perspective of Multi Generations:Take a University in the North as an Example

Under the background of population aging,while the living environment of the elderly is improved,it is necessary to pay attention to their spiritual needs and build an elderly-friendly and livable social environment.In this paper,through field investigation and research on social behavior and space,the social behavior and needs of the elderly in a university in the north were analyzed,and based on the social characteristics and psychological needs of the elderly and students in the university,the construction of a dynamic space with multi-generational shared space as the core was proposed to develop a social platform that integrates virtual and reality,so as to provide reference for the updating of social space in college communities in the future.

Dynamic Vector Space Secret Sharing Based on Certificates

A vector space secret sharing scheme based on certificates is proposed in this paper. The difficulties of solving discrete logarithm assure confidential information＇s security, and the use of each participant＇s certificate makes the dealer have no need to transfer secret information to the participants. The proposed scheme is dynamic. It can effectively check cheaters and does not have secure channel requirements.

Go global to win development space and share growth opportunities

In 2013,President Xi Jinping first proposed the 'Belt and Road Initiative';the First China Textile Industry Go Global Conference was held at the same year.In 2015,National Development and Reform Commission,Ministry of Foreign Affairs and the Ministry of Commerce jointly issued the document of 'The vision and action to promote the construction of Silk

空间共享与共享空间——来自南京的案例研究

Sharing practices are emerging phenomena in the 21st century.The existing literature mainly focuses on sharing practices such as sharing economy,bike-sharing schemes,food sharing,and co-housing regarding the social,cultural,political,and organizational dimensions,while space sharing has been under-investigated.By taking a qualitative case study approach,this paper mainly examined the socio-spatial dimensions of sharing practices through the lens of sharing urban public spaces by neighborhood residents.To better understand how shared spaces are formed and how shared spaces facilitate sharing activities,a public space in a historic neighborhood in Nanjing was selected as a case.Taking account of a specific urban context,the research aimed to understand place-based sharing practices in as many ways as possible.The research findings revealed that the appropriate physical conditions of the public space are the prerequisites for space sharing.In turn,space-sharing practices could enhance the sense of community and social cohesion.However,some negative effects,such as homogeneity in social groups and privatization of the public space were identified as well.The implications for policy-making and planning practice were also provided.

A Computer-Aided FPS-Oriented Approach for Construction Briefing

Function performance specification (FPS) is one of the value management (VM) techniques developed for the explicit statement of optimum product definition. This technique is widely used in software engineering and manufacturing industry, and proved to be successful to perform product defining tasks. This paper describes an FPS-oriented approach for construction briefing, which is critical to the successful delivery of construction projects. Three techniques, i.e., function analysis system technique, shared space, and computer-aided toolkit, are incorporated into the proposed approach. A computer-aided toolkit is developed to facilitate the implementation of FPS in the briefing processes. This approach can facilitate systematic, efficient identification, clarification, and representation of client requirements in trail running. The limitations of the approach and future research work are also discussed at the end of the paper.

Architectural and personal influences on neishborin8 behaviors;

Architectural and personal influences on neighboring behaviors were studied in a residential neighborhood using both qualitative informal conversations, and systematic recording of activity in the neighborhood＇s social space. This dual approach produced new insights into neighboring behaviors and social networks. It was discovered that the residents who participated in the social space were only a portion of the resident population. There was an additional neighborhood-based network whose neighboring was not conducted in the social space; instead it was maintained by direct house-to-house contact. It was also found that some individuals chose not to participate in any neighborhood social network. The social space was an effective neighboring venue for those residents who chose to use it, but did not attract commingling of groups. Contrary to an assumption in previous neighboring research, there are social groups which develop and maintain themselves without participation in a social space.

Secure Sensitive Data Sharing on a Big Data Platform

Users store vast amounts of sensitive data on a big data platform. Sharing sensitive data will help enterprises reduce the cost of providing users with personalized services and provide value-added data services.However, secure data sharing is problematic. This paper proposes a framework for secure sensitive data sharing on a big data platform, including secure data delivery, storage, usage, and destruction on a semi-trusted big data sharing platform. We present a proxy re-encryption algorithm based on heterogeneous ciphertext transformation and a user process protection method based on a virtual machine monitor, which provides support for the realization of system functions. The framework protects the security of users＇ sensitive data effectively and shares these data safely. At the same time, data owners retain complete control of their own data in a sound environment for modern Internet information security.
