This paper presents an empirical investigation to study the effects of virtual social networks on entrepreneurial marketing. The study designs a questionnaire in Likert scale based on a model originally developed by Morris et al. (2002) [Morris, M. H., Schindehutte, M., & LaForge, R. W. (2002). Entrepreneurial marketing: a construct for integrating emerging entrepreneurship and marketing perspectives. Journal of Marketing Theory and Practice, 10(4), 1-19.]. The study considers the effects of three components of virtual social network (VSN); namely structural VSN, interaction VSN and functional VSN on entrepreneurial marketing. Using structural equation modeling, the study has determined positive and meaningful effects of all three VSN components on entrepreneurial marketing.

Entrepreneurship takes place either individually or organizationally and they normally undertake the risk of entrepreneurship. Entrepreneurs experience the most severe conditions when they deal with a government, which is completely unfamiliar with some rules.

This article provides definitions, features and the effective factors on realization of an entrepreneur government with respect to significance of such a government. To this end, a list of factors that may lead to realization of entrepreneur government was derived from previous studies and then the fuzzy TOPSIS method and collected opinions of experts were applied to facilitate the determination of each of these factors. Finally, a list of influential factors was presented with regards to effective factors on realization of entrepreneur government.

Measuring the relative efficiency of similar units has been a popular research especially when the units were mostly non-financial. Even, similar financial units may not be necessarily evaluated based on traditional financial figures such as return of equities, return of assets, etc. In this paper, we present an empirical investigation to measure the relative efficiency of 30 branches of an Iranian bank named Bank Mellat. The study considers four inputs including operating expenses, interest paid, capital expenditures and fixed assets. In addition, we use customers’ bank deposit, commissions and loans paid as output parameters. Using three different data envelopment analyses, the study measures the relative efficiencies of all units. The preliminary results indicate that most banks were working under desirable level of efficiency.

This paper presents an empirical investigation on the effects of the computer games on some female students who attended the secondary schools in Iran over the period 2013-2014. The population of the survey includes 7542 female students who attend secondary schools in Babol County, Iran. The study selects 364 people as a sample and the sampling was accomplished based on random cluster way. The necessary data were collected using two questionnaires of computer games and decline of study with 25 questions in Likert 5 points and there were validated by experts and specialists in the field of educational technology and psychology. In addition, Cronbach alpha was calculated as 0.828, which was well above the minimum acceptable level. Using Pearson correlation test as well as one-way t-student, the study indicates that most female students of secondary school in Babol County used computer games. In our survey, there was a strong relationship between computer games with decline of study and study motivation, and there was a weak relationship between computer games and learning of girl students of secondary school in Babol County.

Research has been done on evaluating the performance more emphasis either on the technical aspects of the performance evaluation or considers only one aspect of banks such as sales, revenue, etc. This paper presents an empirical investigation to measure the relative efficiency of different banks using a hybrid of K-means and Grey relational analysis. The study uses eight criteria such as resources, customer satisfaction, etc. for clustering different banks and using Grey relational analysis provides ranking of different branches of a bank named Bank Qarzol Hasane Resalat located in city of Tehran, Iran.

Nowadays, the issue of “globalization” is entering to all areas in the world. In addition to products and companies, cities and countries also have the opportunity to see themselves as important actors in international arena. Places define their positions in different fields like business, leisure and recreation, educational opportunities, living, etc. This paper presents an empirical study to introduce city branding as one of the solutions to join globalization process. The method of this research is based on the “descriptive-analytic” and utilize the available literature and experts’ opinions to prioritize the influencing factors of city branding. We use Delphi consensus methods and technique of analytical hierarchy process to evaluate the factors. Finally, the results of the study indicate that security, transportation and mental creativity are the weakest fields and business and shopping facilities are strong fields of city branding in metropolitan of Tehran.

Application development and e-learning services in the context of communication networks and information along with qualitative and quantitative improvements of activities and services can expand some of threats which emergence in the networks of this infrastructure of telecommunications. Consequently, this is an inevitable necessity attention to accuracy and efficiency payment issues and security concerns to managers and decision makers. Based on other researches and effective experiences in the field of e-learning security, this research attempts to define a logical structure to security contents in this field. We have presented a three-dimensional model for security issues and requirements of e-learning, based on the findings of research. Actuarial three-dimensional model are infrastructure-oriented viewpoint; service-oriented viewpoint and customer-oriented viewpoint. Each of these three dimensions in this model has described in the form of model with two fields: e-learning issues and security of e-learning issues.
