Conceptual Model

This research is a survey and exploratory study to present a conceptual model for the sustainable development of Iran based on social entrepreneurship. Its approach for conceptual modeling is based on Path Analysis through Multiple Regression Method. The study has benefited from five questionnaires (four for the Delphi Method’s rounds and another for the conceptual modeling itself). The statistical population of conceptual modeling section includes three public organizations of Iran: "State Welfare Organization ," "Department of Environment ," and "Ministry of Cooperatives, Labor and Social Welfare ," which reflect the pivotal SD concepts of society, environment, and hence social economy, respectively. After setting a conceptual framework, the preliminary conceptual model was formed accordingly. Each path on the model was equal to a hypothesis. Finally, a statistically significant SD-based conceptual model of social entrepreneurship, which passed goodness-of-fit by Coefficient of Determination ( R² ) was presented.

Regarding to design an applicable electronic book reading system for children and adolescent, this study’s struggle is to prepare a conceptual model. We used quantitative approach and Delphi method in order to analyze data. In this regard, criterion based sampling is used to identify the research population. 15 experts were identified which had criteria such as having subjective publications, teaching experience, and so on. We supposed that these experts could present more information that we expected to collect. Moreover, 8 electronic book systems were selected to be reviewed, because of their plenty of active audiences, and their international and also standard presence. Firstly identified practical criteria in designing electronic books by extracting them from related resources and checking active systems. These data helped us to prepare primitive version of the checklist and it completed after passing validity control step with participation of three experts. Then the checklist presented to experts in Delphi panel. Finally, consensus on the components was reached after three rounds of Delphi panel. The results showed that in designing electronic books for children, there are five original components. The components are display screen features with 12 criteria, screen organization with 13 criteria, interaction and feedback with 8 criteria, search and retrieval features with 10 criteria, and help and guidance features with 10 criteria. Consequently, display screen features with score of 3,706 and interaction and feedback with score of 3,700 were selected as the most important components in designing electronic book systems by the viewpoints of Delphi experts.
