The systems dynamics emphasize the participation of individuals in modeling as well as modeling evaluation. In recent years, participative model building methods have been developed, both individually and in groups, as well as crowd model building, which are based on the mass participation of people through the Web 2 and social networks. However, so far no systematic study has been done to evaluate the effectiveness and compare these modeling methods. On the other hand, in the development of modeling methods, especially crowd model building; special features and characteristics have been enumerated for each of them, which needs to be carefully examined by evaluating them. Therefore, this article seeks to systematically evaluate and compare the crowd and group model building. For this purpose, these two modeling methods have been studied through an online questionnaire. The results showed that the participants acknowledged the positive effect of crowd and group model building sessions in achieving the goals as well as the importance and usefulness of these sessions. However, the results showed that crowd model building is more useful in recognizing different dimensions of crowdfunding with a divergent view, dissemination of topics, and culture building in society, while group model building has been more useful in deepening peoplechr('39')s knowledge of the dimensions of crowdfunding with a convergent view, increasing the commitment of individuals. The results also showed that the diversity of individuals and the informal structure of the sessions have a significant effect on the success of crowd and group model building.

The main objective of this paper is to provide interaction of ecosystems with each other (ecosystems-ecosystems) through the value-creating ecology. Ecology is used as a metaphor for information systems in organizations. The main difference between the ecology of creating value with the supply chain and the value chain is that the value-creating ecology is a network value chain. Therefore, since ecosystems have a wider concept than the network and are more complex, the use of value-creating ecology for interactions between ecosystems will be more efficient, and thus produced ecological values. First, using the qualitative analysis method, the theme is related to each of the categories and with the analysis done by the software, correlation between the categories identifies. Then, through a questionnaire containing 135 questions, each of codes are given in the coding phase, measure regression and correlation between the categories. Composite Reliability measured the validity of the theme. On the other hand, the ability to communicate effectively between SMAC ecosystem and the digital business ecosystem through the value-creating ecology has also been tested, which result of this test confirms the effectiveness of this interaction.

Problem definition is the most vital and important step in system dynamics approach. It is the basis for other steps of dynamic modeling and one of the main conditions in the effectiveness of modeling and its success. Considering its importance, there is scant literature on process of problem definition and attributes as well as indicators of dynamic problems. With aims to explain the problem definition, this article creates problem definition framework through the systematic and structured process by extracting the indicators and factors that determine a dynamic problem. At this point all the articles listed at the first two rounds of system dynamics research conferences in 1976 and 1981 and also 33 around of the system dynamics conference from 1983 to 2015 as well as the Journal of System Dynamics Review (SDR) and scientific databases include Elsevier, Wiley, Springer and Emerald were examined. Finally, a framework was designed with 6 indicators including structure of the problem, problem`s stakeholders, border of problem, problem complexity, dynamics and nature of the problem, which altogether consists of 24 indexes. A comprehensive framework for the diagnosis of dynamics problem is main finding of this paper.

Surfing sites of renowned Iranian firms, it can be recognized that they are just using few of web 2.0 tools such as social networks and RSS for achieving their business goals. Enterprise 2.0 is a new concept and it effects all dimensions of organizations. Therefore getting ready for it before implementing Enterprise 2.0 concepts and technologies in the organization is essential. The goal of this paper is presenting an Organizational Readiness Model for Enterprise 2.0, by which firms can calculate their organizational readiness for Enterprise 2.0. For this purpose, after reviewing literature, an initial model was developed and after asking the opinions of experts, final model was developed. The final model includes 5 stages for Organizational Readiness named Stimulation of Interest, Initiation, Legitimization, Decision to Act, and Action. It is also composed the factors named High market risk, External and social pressure for Enterprise 2.0 adoption, Familiarity with Enterprise 2.0 benefits, Fitness of needs with Enterprise 2.0, Existence or development of Enterprise 2.0 goals and strategies, Alignment of Enterprise 2.0 goals with organizational goals, Positive attitude and tendency of management and employees toward Enterprise 2.0, Senior management support and commitment, Presence of an appropriate organizational culture, Presence of pioneers and champions, Presence of a good and qualified technical team, Presence of a flat organizational structure, Determining the target audience, and Holding Enterprise 2.0 training programs and seminars.

Over the years, political behavior has been one of topics of interest to researchers in the field of organizational behavior. The reason for this interest is the extensiveness of this type of behavior in the organizations. This study, with regarding political skill and political will as moderating variables, considers the impact of perceptions of organizational politics on political behavior. The statistical population consists of managers and workers of water industry. In this research, the stratified (classified) sampling is used. To collect data, the questionnaire from five-option Likert scale was used, and the validity and reliability for each variable were confirmed. The data analysis was done by structural equation modeling, and path analysis by using LISREL software and Smart PLS. The results showed that perceptions of politics lead to political behavior, and political will moderates the relationship between the perceptions of politics and the political behavior. In this research, the moderating role of political skill was not confirmed.

With the rapid growth of the Internet, e-learning has been prevailed in various societies. Despite the emerging trend of using web-based learning systems to facilitate teaching and learning activities, the number of users of web-based learning systems is not increasing as fast as expected. In this research, an integrated model has been used in order to assessing the influence of IS-oriented, psychological and behavioral factors on instructors’ adoption of web-based learning systems. To examine the research model, collected data from 115 university instructors were analyzed using structural equation modeling. The results showed that subjective norm and information quality have positive effect on perceived usefulness; also, self-efficacy, service quality, subjective norm and information quality are effective on perceived ease of use. In addition, perceived usefulness, perceived ease of use and system quality all increase instructors’ intention to use web-based learning systems; however, perceived usefulness is the most important factor affecting on intention and actual use of the system (adoption).

In recent decay development of different technologies is dramitically high and it influences in services. One of fields which is affected from information technology is bankining industry. Wireless technology is one of the information technology fields that has a greate development in recent years which resualt of that is mobile banking service. Banking industry is a smple that uses data mining technique. Data mining is kind of exploring knowledge to solve a special problem. In this research 232817 data is used to find some models by artificial neural networks and naïve bayes techniques in according with customers' attributes. Furtheremore result of this research help to classify customers who use mobile banking service and then the bank can offer the service to somebody who are in this classification but donot use this service. So in this way the bank can attract more customers, maintain its customers, and keep high customers' satisfaction. Also the research reveals that artificial neural networks is more accurate than naivie bayes and the research's hypothesis is proved.

In order to evaluate and select the appropriate knowledge management strategy, a lot of organizational factors must be considered. On the other hand, in the approach of dynamic knowledge management strategy; the processes of creation and transferring of knowledge have direct effects on the selected strategies. The human-oriented and system-oriented approaches of knowledge management strategy are essentially different and need different infrastructures, methods and tools. In this research, the related literature about developing knowledge management strategy has been reviewed. The effective factors on knowledge management strategy have been extracted from different conceptual frameworks, models and methods. Then a comprehensive methodology for developing knowledge management strategy has been presented.
The factors of this methodology, which have direct effects on the final chosen strategy, include: general business strategy, organizational structure, cultural factors and knowledge creation process in knowledge intensive area of the organization. Also in this methodology, the interrelated effect of information technology strategy and human resource strategy on the knowledge management strategy is considered and the final strategy is shown ranging from human oriented approach to system oriented approach.

Information systems security (ISS) is a critical issue that organizations face world wide. Information systems security involves both technology and people (human factors). The focus in most researches on information systems’, security as a technical issue has dominated ISS researches and practices.
Lately, a new paradigm is emerging, addressing it as a “people issue” and an “organizational issue”. In that paradigm, people are the weakest element in the information systems security.
The present research takes a different perspective on ISS by focusing on “behavioral information security” and with considering the general lack of empirical research and the importance of information security to modern organizations, it presents a managerial framework for explore the role of human factors in ISS. Specifically the purpose of this research was to identify and model the critical managerial constructs that mostly influence the effectiveness of ISS.
The methodology of this study combines both qualitative and quantitative research techniques. Through a qualitative technique and investigating the research literature, identified key constructs in information systems security were identified. Then developed mod was based on the effects of these constructs on the information systems’ security effectiveness. Then based on the research literature and scholars ideas, a questionnaire was developed and distributed in some organizations. The data obtained were analyzed with SPSS and LISREL software. The results of empirical analysis supported and
validated the model.
