Community detection is one of the emerging and well-known topics in the area of data mining and social network analysis, which has wide variety applications in discovering communities in real-world networks such as biological networks, internet weblogs, scientific and research websites, etc. Web community detection can especially help admins assign the optimal bandwidth to the websites of theirown networks. Most of web community detection approaches only use the network topology to discover the web communities. However, the results of the most recent researches show that traditional community detection methods have to be substantially modified to consider web attributes as well as network topology. Therefore, in this paper, a mathematical programming approach is developed for community detection in attributed internet networks by simultaneously considering both network topology and node attributes. In this approach, first, similarities of web pages are calculated using node attributes and a desired similarity measure and are considered as the weight of the corresponding edges. Then, communities of the resulted weighted network will be detected by the proposed mathematical model. To validate and prove the efficiency, it is hypothesized that the detected communities of the proposed approach have a better quality than that of previous models. Experimental results demonstrate that the proposed approach has the ability to significantly improve the quality of detected web communities, when the model uses the Jaccard index. However, the results of other hypotheses indicate that the correct selection of similarity measure has a significant impact on the quality of the detected communities.

In this research, the distinction between identity of young people in the real world and the virtual world is considered as one of the important issues of cyberspace. The definition and representation of individuals of their identity is somewhat different in the real and virtual world, due to the prevailing conditions in these two worlds. Using this space together with various advantages and disadvantages has faced us with a variety of issues, which one of those is identity, identity crisisand identity discrepancy.Theoretical framework of research had been presented based on the views of sociologists such as Giddens and Stewart Hall on identity; Graebner, Neumann (the influence of mass media); Scheler, stone, Ringgold, Miller and Thompson (Cyberspace and Identity); Anderson (the paradigm of double world and the emergence of simultaneous identities), and consequently, a research model was designed.The statistical population of the study were young people 18 to 35 years old in Yasouj, (45312 people). According to the Cochran formula, 380 people were selected by multistage cluster sampling method, and the data were collected using questionnaire.Finally, the overall research hypothesis was confirmed: there is a significant difference between the true identity of people in the real world and their identity in the virtual world, and the results showed the difference between different dimensions of identity in real space and virtual space, and identity differences (self-discrepancy) in some dimensions is significant based on the variables such as age, gender, education, income level and the amount of use of cyberspace.

The main purpose of the present research is to provide a native pattern of post-crisis management in archives. Identifying the main fields and strategies as well as the main factors that interfere in the management of the indigenous issues of Iran's archives crisis are considered as secondary research objectives. This research was carried out qualitatively with the use of grounded theory and the data were collected through deep semi-structured interviews. Data saturation was a major factor in determining sample size. The research community was crisis management specialists, as well as archives managers in Iran. Data analysis was conducted through theoretical coding, which consists of three stages of open, axial, and selective coding. In the axial coding, the main phenomenon or category was identified and in the selective coding stage, the model was presented. In this pattern, the context, the causative conditions, the main strategies, the interveners (mediating conditions) and the consequences of crisis management in the archives were identified. The results of this pattern include the sections of the causal conditions, strategies, intervening conditions and the field, as well as the outcome of them.The causal conditions are due to factors such as the lack of proper policies at the national level for post-crisis management, the lack of proper and up-to-date equipment to accelerate the rescue of materials and to combat fire, as well as the absence of organizations that do the act of freezing and falsifying records. Intervener conditions and areas is consisted of some issues such as the lack of a comprehensive crisis plan for the post-crisis phase in the archives, compliance with standards in the reconstruction of records by specialists, the use of disinfection and acidification methods to protect information resources against pests, use of the crisis map in the post-crisis phase and issues related to manpower. According to research findings, in archives, strategies such as modern resilience training, restoration of records, evaluation of building aftershocks, standardization of buildings and equipment, reconstruction and restoration of documents damaged by biological crises by installers, and coordinating with organizations for the restoration of records at the city and state level due to accelerated reconstruction of records should be used. Eventually, the aftermath of the crisis management process in Iran's archives will have the effect of eliminating the effects of crises and returning to the pre-crisis stage.

Internet research ethics (IRE) is recognized a subfield of applied ethics, so that as an interdisciplinary field involve different scientific and technical fields. The aim of IRE, studying and applying ethical guidelines to realize research purposes, in particular with attention to research human subject. This research is realizing under a descriptive approach, a documentary research and based on a qualitative analysis. Early, there is defined ethical decision-making in internet research with referencing to technical, original and updated resources. Then, there are argued ethical decision-makings must be based on research situations in internet environments, so that there are adopted in case and based on a bottom-up approach. Two indicators of the internet facilities and the ethical issues are recognized fundamental components to study and analyze the moral challenges in internet research. These indicators could accept some flexibility to explore various ethical situations in Internet research to avoid providing universal ethical instructions (or codes) and only rely on advice or provide moral insights.Theseindicators forms table components of moral situations in internet research. This table helps researchers to ethical decision-making in varied situations to suit the context of the moral position to recognize and analyze its expression in the Internet environment.

Nowadays, one of the reasons for the failure of companies is the low level of their innovation in them. The reason of this is, firstly, lack of maturity in the field of innovation and, secondly, lack of attention to the knowledge of customers. Considering that one of the main sources of innovation in organizations is the exploitation of customer knowledge, however, limited research has been done on the ability to innovate based on customer knowledge. The main objective of this research is identify the components of customer knowledge based on innovation and provide them in the form of levels of capabilities maturity model.All researches on the innovation maturity model and customer knowledge were investigated by meta-synthesis method and 16 articles were selected. Based on the content analysis of the related articles, a set of dimensions and components innovation capability based on customer knowledge was identified and the innovation capability maturity model based on customer knowledge consist of 33 codes, 13 concepts and 5 main categories in five levels of maturity was presented.

The purpose of this study was to identify effect of human factors on information security in education departments of Gonbad-e Qabus and Maraveh Tapeh. In this study, the effective variables on information security were selected from the human resource dimension and viewpoints of managers and employees toward their impact on security were evaluated and given the importance of security for today''s organizations, a managerial model was proposed to investigate the role of human factors in the security of information systems. The research is the applied research method which has been done in a descriptive - survey method and 103 employees who were most used by computer and network were selected as a statistical sample using the purposeful sampling method. The data collection tool was a researcher-made questionnaire (including seven variables) which using SPSS software and its reliability coefficient is 0.99% was calculated and the content validity method was used to determine its reliability and validity. The data analysis was carried out using the LISREL software. The Results show that from the viewpoint of education staff in Gonbad-e Qabus and Maraveh Tapeh, The support of the higher management of the education department, the training of users, the security culture among users, users'' skills, strengthening the policy of users, self-efficacy and experiences of users have a direct impact on the effectiveness of information systems security which ultimately leads to improve the security of information systems. In addition, Lisrel’s output shows that all dimensions (high management support, training, security culture, user skills, policy enhancement, self - efficacy, self - efficacy and experiences) have a high operating load with the desired structure, the same as the effectiveness of information system security and with 95% confidence, it can be stated that fitting this model is acceptable.

Project-based organizations are one the most challenging structures in the realm of knowledge governance due to their specific constraints and also a great potential for improvement in knowledge and learning processes. But these challenges have been rarely addressed in the related research and practice. This research attempts to present a clear and comprehensive understanding of the concept of knowledge governance in project-based organizations by following the mixed research approach using Meta-Synthesis and Delphi methods in an exploratory manner. The proposed framework of the research consists of 194 conceptual elements arranged in 6 dimensions, 19 categories, and 169 components. The identified categories are the “Purpose”, “Process”, “Structure”, “Mechanism”, “Context”, and “Approach”, each part of which defines “why”, “what” and “how” knowledge governance in project-based organizations. The proposed conceptual framework provides a solid basis for understanding the different aspects of knowledge governance in project-based organizations, and by addressing the challenges facing the project structures in the area of knowledge processes, it provides a platform for designing and implementing effective solutions for knowledge governance in such organizations.
