Despite the increasing importance of data and information quality, current research related to Big Data quality is still limited. It is particularly unknown how to apply previous data quality models to Big Data. In this paper we review Big Data quality research from several perspectives and apply a known quality model with its elements of conformance to specification and design in the context of Big Data. Furthermore, we extend this model and demonstrate it utility by analyzing the impact of three Big Data characteristics such as volume, velocity and variety in the context of smart cities. This paper intends to build a foundation for further empirical research to understand Big Data quality and its implications in the design and execution of smart service ecosystems.

The aim of this study is to analyze the factors affecting the acceptance of electronic health on the basis of the theory of planned behavior. E-health is a growing field of health communication that entails using medical informatics, public health, and trades. As a result, E-health facilitates the provision of health information and services through the internet and related technologies.

The results have shown that the most important factors affecting the acceptance of e-health are:  1. Organizational related factors of e-health services; 2. Human-related factors of acceptors; 3. Environment-related factors; 4. Factors associated with financial sources and expenditures; 5. Technical and infrastructural factors. Taking advantage of interpretive structural modeling, we demonstrated these factors and determined the level of their reciprocal relations.

Purpose: The purpose of research is to observe the influence of public trust on accepting KBOs. The implementation method of the research is descriptive (non-experimental) and with correlation analysis model formed by structural equations used the least minor squares. Methodology: The participants of the survey were consumers of KBO services. According to Cochran formula for unspecified society ,384 individuals were chosen as statistical sample selected totally random.

To measure social trust, Safarinia and Sharif questionnaires were used. (1389). due to receptivity of knowledge-based organizations, researcher-made questionnaire were utilized. this questionnaire contains 5 elements which composed based on available questionnaire. We realized there is a meaningful and significant relation between KBO admission and all aspects of social trust. the influence of social trust on KBO’S admission was positive and meaningful. The influence of social trust on KBO’s admission is positive and meaningful. Findings: According to the results,72% Variance model in knowledge-based organizations admission were indicated by Research model. Therefore, we realized strengthening social trust will bring acceptance to KBO’s presence. Discussion: In this regard, managers and officials in KBOs must concentrate on gaining and obtaining social trust in case of adequate social acceptance.

Purpose: The notion of “gender segregation” in the universities has often been challenged with different concurring and opposing theories. The issue has been further highlighted in Farhangian University. Although all the qualifiers in this university, prior to and during admission process, have been cognizant of such gender segregation, some elicit resistive responses pursuant to admission and passing some semesters, and then they present their commentary on the relevant implications. The present research seeks to investigate the consequences to gender segregation form the students’ perspective. Methodology: By applying a semi-standard interview and a purposive-qualitative procedure, an in-depth interview was performed on 33 students studying at least 5 semesters in the university, and the interview was terminated based on theoretical saturation. For data analysis, grounded theory was applied. Finding: The research findings were divided into 18 principal categories, and the category “dubiety (Tashkik, in Islamic Terminology) over gender segregation” was semantically reconstructed. The consequences of the dubiety were categorized in the two groups including consensus and inconsistent (i.e. contradictory) consequences. Conclusion: In the end, the research findings were presented in the form of a researcher-made model.
