Given the fact that tourism is an important sector of many national economies, it is very essential to examine the factors which can help develop successful and smart tourism experiences. The importance of developing tourism destinations through smart technologies as a strategic tool to develop tourism has persuaded many countries to explore the implementation of these destinations, their models, components, and policies. The present study proposed a model for developing online tourism services in smart tourism destinations. The model was analyzed via structural equation modeling using SPSS (version 20) and Lisrel (version 8.8). The data analysis identified 21 components in six major dimensions which can affect smart tourism development: online content quality, access to interactive online services, end-user internet service, demand for online services, the utilization rate of location-based services, and level of online services. The identified factors can help researchers gain a better understanding of the factors affecting the development of smart destinations and recognize their importance and their degree of influence and power. It is recommended that more attention be paid to improving the quality of services provided to tourists for developing smart destinations. [ABSTRACT FROM AUTHOR]

This paper contributes to identify systematic problems in NIS using Thinking Process (TOC-TP) and to eliminate the bottlenecks, which results in improving the innovation process and efficiency of NIS. The Case study in this research is the NIS of Iran. The national documents of the innovation system were studied and all problems of NIS mentioned in documents were gathered. The causal relationships between the systematic problems were identified by the survey and grouped into 6 components by Exploratory Factor Analysis: weakness in technology diffusion mechanisms, the lack of centralized governance on science and technology policy, the government's pivotal role as an executor in education and research, weak laws and regulations in the field of research and technology, the lack of adequate financial resources in R&D and the lack of any perspective on the creation of wealth and entrepreneurship among the actors of research and technology. Finally the bottleneck of Iran's NIS was recognized by Thinking Process tools: the small participation of private sector in research and education system as the result of government's pivotal role as an executor of Iran's national innovation system. So the researchers could diagnose the policy gaps related to the identified bottlenecks. [ABSTRACT FROM AUTHOR]

Abstract: Purpose: The purpose of this study is to evaluate the extent and potential correlates of sexual risk-taking behaviors among adolescent boys aged 15–18 in metropolitan Tehran. Methods: Data were collected from a population-based, cross-sectional survey of adolescent males (ages 15–18) residing in Tehran, Iran. Of 1385 subjects, 382 reported sexual experience (27.7%). The article is mainly considering sexually experienced subjects. Two factors were considered as sexual risk-taking behavior (“not using condom or inconsistent condom use in sexual contacts” and “ever had multiple sexual partners in lifetime.” Several other factors were considered as independent variables and their relations were assessed using t test, χ2 test, and logistic regression models. Results: Having no access to Internet, feeling regretful at sexual debut, having one sexual partner in lifetime and lower knowledge of condoms are predictors of condom non-use. Older age, using alcoholic drinks, early sexual debut, and poor knowledge of reproductive physiology are predictors of multiple sexual partners among adolescent boys aged 15–18 years. Conclusion: Appropriate interventional programs should be implemented for adolescents in Iran to encourage and enable them to delay first sex and abstain unwanted and unplanned penetrative sex, to stress the health risks of alcohol use in terms of sexual health and finally to enhance their knowledge on different aspects of reproductive health particularly prevention against STI/HIV.
