  In a research, that this paper reflects its results, a model for stating the relationship between investment in IT and customer satisfaction was developed. This study starts with extensive literature review on investment in IT and customer satisfaction. Then, a conceptual model with four criteria (including Economic, educational, diffusion of ICT and telecommunication) and one latent variable (indicator of customer satisfaction) were designed. This model’s primary validity was approved through expert opinion. Then, in a field study in the organization under study, the required data have been gathered for testing functional approval of the model. In the next stage of research, by using SEM techniques and interactive regression equation in the form of path analysis and using the software like SPSS and LISREL , we concentrated the factors of relationship between latent variable and observed variables. The finding of the research shows direct relationship between economic and educational factors of IT investment on customer satisfaction. Manuscript profile

  Mobile Government Ecosystem is one of the emerging ecosystems in Iran. The purpose of this paper is to identify and analyze the structure and identifying the role of each of the key stakeholders of this ecosystem. In order to achieve this purpose, by studying the related literatures and the models presented in these literatures, a mobile government ecosystem conceptual model is proposed, where four new key stakeholders are introduced: new trends in over the top (OTT) services, innovation and innovators, advertisement and advertisers, and mediators. Then, a questionnaire is designed to verify the factors identified in the model and to examine the effects of these factors on the mobile government ecosystem. The questionnaire was distributed to a random sample of 400 experts, where 363 responses were collected, and analyzed based on structural equation modeling. The results show that with the exception of advertisement and advertisers, the three other key stakeholders have significant coefficients in the model. Manuscript profile

  The method of crowdfunding in the world has expanded rapidly due to the need for financing in the early stages of start-up businesses as well as advances in information technology. In Iran, several financing platforms have been established so far, some of which have been successful and some of which have been unsuccessful. Therefore, it is necessary to help the development of this method by examining the factors affecting it. Since mass financing is a new and new phenomenon, it is necessary to increase its awareness in the society in an appropriate way while determining the factors affecting this method. The collective modeling method is based on social networks and the Web 2 with the aim of recognizing new phenomena. Therefore, in this article, using collective modeling, the factors affecting crowdfunding in Iran in order to support start-up companies in the field of IT are discussed. Manuscript profile

  The Iran’s national enterprise architecture framework (INEAF) has been adapted from the TOGAF framework and its architectural development method. In this framework, the use of agility paradigm is emphasized, but there is no basis for using agile methods and techniques. Based on the results obtained for the researcher, the studied sources did not indicate all the necessary solutions and features to develop an agile methodology based on the Iran’s national EA framework. According to Mr. Gill research, each modeling standard is different in scope and function, and since a modeling standard alone cannot support all the requirements of agile enterprise architecture, combining modeling standards is a suitable solution. In this paper, an agile enterprise architecture modeling methodology including ten solutions with a combination of six modeling standards ArchiMate, UML, BPMN, FAML, SoaML and BMM based on the Iran’s national EA framework is presented. The evaluation of the applicability of the proposed methodology is performed by the combined method (qualitative + quantitative). Qualitative evaluation is performed through a case study and quantitative evaluation is performed using multi-criteria decision making methods including ANP and DEMATEL. Data collection and information gathering and determining options and criteria, is performed through library studies and field methods, and using questionnaire, interview and observation tools. Based on the case study, combination of six standards by agile enterprise architecture modeling method based on the Iran’s national enterprise architecture framework is applicable. For quantitative evaluation of applicability in this paper, according to experts, four options have been proposed, which are based on the final weight: support by known tools, the ability to cover the artifacts of the Iran’s national enterprise architecture framework, efficiency or effectiveness, ease of learning or teachability.

  Stock market prediction serves as an attractive and challenging field for researchers in financial markets. Many of the models used in stock market prediction are not able to predict accurately or these models require a large amount of input data, which increases the volume of networks and learning complexity, all of which ultimately reduce the accuracy of forecasting. This article proposes a method for forecasting the stock market that can effectively predict the stock market. In this paper, the past market price is used to reduce the volume of input data and this data is placed in a regressor model. Manuscript profile
