In recent years, the topics related to electronic learning have attracted the attention of many scholars. Despite the increasing attention of researchers to the study of electronic learning systems, the focus on outcomes and the results from the use of these systems has been less considered. The present study is designed to investigate the effects of the use of electronic learning systems on its outcomes. To this end, 3 major outcomes from the use of an e-learning system, including learning support, communication with others (social structure), and educational performance, have been investigated, taking into account the mediating role of perceived adaptability. The statistical population of this study is the students of Mehr Alborz University who currently use the electronic learning system. The results of this research indicate a positive and direct relationship between the use of the e-learning system and its outcomes. Also, the mediating role of perceived compatibility factor has been confirmed in this research.

This research aims at associating two groups of demographic and transaction related factors and furthermore, proposes customer churn factor as another influential factor in customer value analysis. To this end, at first, customers' transaction data in a real local ISP in a four year period are utilized for segmentation purpose using k-means method. Regarding service nature of the case, customers' behavior has been considered in terms of customer satisfaction factors. The results of Exploratory Factor Analysis (EFA) indicate that three factors of service quality, expectation confirmation and post-purchasing satisfaction are influential factors. Then, association rules using GRI algorithm are exploited in order to investigate among customers' behaviors and propose appropriate strategies and action plans for each customer segment. Finally, segmentation results are associated with physiographic variables and existence of a significant difference among identified segments is more investigated using one way ANOVA test. The results clarified that expectation confirmation and post- purchasing satisfaction as hygienic factors and service quality as an incentive factor influence customer loyalty.

Information technology tools with its attractions play an important role in the lives of people and makes people to interact closely with these tools, which can lead to a social isolation. This study was designed to determine the possible association between the use of these tools and the youth depression level. To this end, after designing research model, considering the available 390 IT tools such as mobile, social networking sites and computer games, youth users were selected randomly to complete the designed questionnaire and for the purpose of data analysis Partial Least Square (PLS) method was used. The results showed that there is a positive relationship between the use of computer games and depression. However, no significant association was found between the use of mobile phone and depression and also the relationship between the use of social networks and depression level was found to be negative.

Nowadays, with the development of organizations and complexity of business processes, the management and control of such organizations are much more important than before. Therefore, having a determined prospect toward Business Processes Management (BPM) is significant. Since the BPM systems are electronic systems and they are used for supporting, monitoring and managing the processes and other activities in the organization, therefore for preventing misemployment of valuable resources in applying BPM systems and the protection of organization against possible risk of system application, it is necessary to be aware of the critical factors before taking any action. Accordingly, this research paper is conducted to present critical success factors for the implementation of BPM systems in Iran. In this regard, 34 critical factors were identified and presented to the experts through a questionnaire and the answers were analyzed using exploratory factor analysis method. The statistical population consists of managers, experts, suppliers, and developers of information systems having at least 3 years of experience in BPM systems. The designed questionnaires were distributed among the statistical sample and 128 completed questionnaires were returned and analyzed. Finally, 27 key factors categorized into 5 main groups as the following priorities: managerial, organizational, procedural, human-related, and technical. The result of this research can assist the suppliers and the users of BPM systems either in successful application process or confrontation with possible troubles.

Implementation of Enterprise Resource Planning systems (ERPs) is a complex and costly process which usually results in serious risks. The majority of previous research projects have been conducted in identifying ERP Critical Success Factors (CSFs) in order to identify the main factors enhance success achievement. Project managers' skills of ERP system implementation projects as one of such facilitating factors, are not well studied and its different aspects are discussed in the extant literature. With this in mind, this research aims at studying and identifying the most related project managers' skills of ERP system implementation projects which proposes a classification scheme along with a ranking model. The paper, based on the results of the Exploratory Factor Analysis (EFA) categorizes 18 identified skills into four distinct groups of managerial, project management, human resource and technical. The results of this study have provided a very useful reference for scholars and managers to identify the relevant issues of ERP implementation projects managers' skills.

ر The concept of organizational culture is one of the most important organizationalbehavior theories which is also being considered as one of the key critical successfactors of ERP implementation projects. However, this concept is somehowoverlooked in academic research. Hence, the paper tries to articulate therelationship between the two concepts. The study has been implemented in a fieldstudy manner within Iranian companies which have implemented a reputableinternational ERP and had at least nine months of system life. The questionnairetool has also been applied for data gathering in eight real cases. ConfirmatoryFactor Analysis (CFA) using Lisrel and multiple regression method using SPSShave been exploited for data analysis which as a result, all of the five researchhypotheses are statistically supported. In addition, it is implied that thecooperation culture in organizations has the most significant relationship withERP implementation success followed by risk tolerance culture in the second rank.Regarding research results, it seems necessary that it is crucial for managers toimprove their ERP system success level through improving their organizationalculture and plan some actins for this done.

Nowadays, many organizations take Business Intelligence (BI) systems to improve their decision making processes. Although many organizations adopted BI systems, not all implementations are successful. This paper seeks to identify critical success factors (CSFs) that impact on successful implementation of BI systems in organizations. So, at first, through literature reviews, 26 success factors were identified. After that a questionnaire has been developed and then filled by domain experts who had at least three years of experience in ITIL implementation and consultation in Iran. Exploratory Factor Analysis (EFA) has been used for data analysis, which finally classified critical success factors into four groups named as “organizational”, “human”, “project management”, and “technical”. The results of this study provide a very useful reference for scholars and managers to identify the relevant issues of BI projects in Iran.

Most organizations still experience a lack of Business Intelligence (BI) in their decision making processes when implementing enterprise systems, such as Enterprise Resource Planning (ERP), Customer Relationship Management (CRM), and Supply Chain Management (SCM). Consequently, a model and techniques to evaluate and assess the intelligence-level of enterprise systems can improve decision support. This paper proposes an expert tool to evaluate the BI competencies of enterprise systems, and combines a comprehensive review of recent literature with statistical methods for factor analysis. A statistical analysis has identified six factors for the evaluation model: ‘‘Analytical and Intelligent Decision-support’’, ‘‘Providing Related Experimentation and Integration with Environmental Information’’, ‘‘Optimization and Recommended Model’’, ‘‘Reasoning’’, ‘‘Enhanced Decision-making Tools’’, and finally, ‘‘Stakeholder Satisfaction’’. Enterprises can use this approach to evaluate, select, and buy software and systems that provide better decision support for their organizational environment, enabling them to achieve competitive advantage.

Nowadays, many organizations took Information Technology Infrastructure Library (ITIL) best practices in the field of IT service management to improve their service management related processes. Although, many organizations adopted ITIL, not all ITIL implementations are successful. With this in mind, this paper seeks to identify critical success factors (CSFs) that impact on successful implementation of ITIL V3 in organizations based on a mixed approach. So, at first, with the semi structured interviews and literature reviews, 22 success factors were identified. After that a questionnaire developed and sent to domain experts. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) have been used for data analysis, which finally classified critical success factors in five groups named as “organizational”, “human”, “project management”, “managerial” and “process centric”. The results of this study have provided a very useful reference for scholars and managers to identify the relevant issues of ITIL projects in Iran
