Human beings are constantly active to live their everyday life. They spend long hours of their life on working and activity in closed and confined environments. That along with urbanization, mental and psychological traumas and physical harms has led some to think about leisure time and its significance in their life. Meantime, various schools of thought and ideologies attach great significance to leisure time. Islam also recognizes the necessity of tourism, as a prescribed form of leisure time, at individual and social life. In this regard, tourism with a spiritual approach is followed by an intellectual upgrade and spiritual evolution of humans, leading to intellectual and spiritual enrichment. This study has been conducted to examine the status of leisure time and tourism in the holy Quran and hadiths. This descriptive-analytical research, which is based on Quranic verses and hadiths frequently narrated in authenticated books, aims to examine various aspects of leisure time and tourism in the Quran and hadiths. The findings of this research show that Islam views leisure time as a moral issue. Relying on the Quranic verses and hadiths, tourism may be divided into halal (permissible), makrouh (non- recommended) and haram (strictly forbidden). Quranically tourism with a spiritual approach brings about serenity, durability and blessings while being faith-based and beyond gender division.

As a symbol of the Islamic spiritual economy, Waqf has been always present and alive in all aspects of the Islamic countries, and it has attracted the attentions of many researchers of different fields due to its multidimensional functional. Based on their desire for eternity, they defined Waqf in terms of a proverb saying “I benefit from whatever I endow”. In several tourists’ travelogues such as travelogues by Nasir Khusraw, Jean Chardin, etc. has mentioned this spiritual tradition as a humanistic economy showing the effects of Waqf on perceiving the tourist destination. Since the modern generation of tourists look for new experiences, thus obtaining a rich content of this spiritual heritage can satisfy them and help the promotion of humanistic models of economy such as Waqf . In terms of its objective, this is a practical research, and it is descriptive-analytical based on its data collection method. The results are obtained in meta-synthesis of documents, articles and travelogues relation to the Waqf tradition. Indeed, the main objective of this article is to provide the mentioned introduction, promotion and reinforcement to understand the different aspects of Waqf tradition based on the travelogues in order to reinforce the perceived value by the tourists of Iranian cities so that the modeling of these concepts leads to the promotion of this spiritual economy model among the other cultures. The results show that considering the perceivable aspects of Waqf , this intangible heritage can be introduced to the tourists in terms of four main aspects including the emotional, cognitive, functional and social aspects and to promote this spiritual heritage based on the religious background of tourists at the international level with regard to the environmental-humanistic aspects of economy; as in Iranian culture, it is believed that “give bread to everyone who enters this house and don’t ask his faith, because the one who deserves a life for god, deserves a bread for us”.

Given the complexities of supply chain networks, the firms consider modern technologies as a potential factor to improve their supply chain performances. One of these technologies is the Internet of Things (IoT). Hence, the main purpose of this study has been to achieve the conceptual model of the IoT implementation in hospital supply chains. Considering the qualitative nature of the study, relevant articles were specified through library research and collecting the related literature. The outputs obtained were analyzed using the meta-synthesis method and the grounded theory. Then the selected articles were extracted and the grounded theory was used to obtain the conceptual model of the IoT implementation in hospital supply chains. The research results indicated that the model featured 7 main categories, 19 subcategories and 86 codes. The results present a conceptual model for the implementation of the IoT in hospital supply chains including an explanation of the main research category, drivers, prerequisites and enablers, environmental and contextual conditions, challenges, technology implementation strategies, and results and outcomes.

Recommender systems are important tools for users to identify their preferred items and for businesses to improve their products and services. In recent years, the use of online services for selection and reservation of hotels have witnessed a booming growth. Customer’ reviews have replaced the word of mouth marketing, but searching hotels based on user priorities is more time-consuming. This study is aimed at designing a recommender system based on the explicit and implicit preferences of the customers in order to increase prediction’s accuracy. In this study, we have combined sentiment analysis with the Collaborative Filtering (CF) based on deep learning for user groups in order to increase system accuracy. The proposed system uses Natural Language Processing (NLP) and supervised classification approach to analyze sentiments and extract implicit features. In order to design the recommender system, the Singular Value Decomposition (SVD) was used to improve scalability. The results show that our proposed method improves CF performance.

Recently, significant technological changes, greater customer demand and the rise of new business models have triggered a rapid increase in electronic service (e-service) innovations. Now, innovation in the provision of e-services has become one of the priorities of managers in order to gain a competitive advantage. However, few studies so far have explored the determinant factors needed in the organization in order to innovate and implement e-services. The purpose of this study is to provide a comprehensive framework that integrates the multiple factors of e-service innovation. Using the qualitative meta-synthesis research method and after a systematic review of the literature and examination of 61 articles, all factors needed for innovation in e-services have been identified and classified in 4 capabilities, 9 concepts, and 30 codes. The results show that e-service innovation depends on networking, informational, operational and supporting, and strategic capabilities. These capabilities create the required platform for innovation in e-services in the organization. This study contributes to current e-service researches by offering theoretical advances related to innovation in e-services. Furthermore, the capabilities, concepts, and codes identified in this study would be useful as a comprehensive conceptual framework for developers of e-service innovation to plan and evaluate their related initiatives.

Nowadays with the ever-increasing growth in social media platforms and the creation of different forms of online activism, the word known as “Campaign” has become a familiar and useful term in people’s everyday lives. Campaigns with all kinds of social aims especially using Hashtags are run on social media platforms by individuals, charities, NGOs, governments, municipalities and brand companies and with peoples' participation and value co-creation, appropriate results are achieved and the desired changes are made in people’s attitudes and the behavior of individuals, businesses, or governments. Therefore, there seems to be a new form of a virtual public sphere where there is action, dialog and social mobilization, which leads to the formation of public opinion and social change in the digital era. In this paper, using a critical review method, we are going to investigate a public sphere's literature and study its core features (1. access, 2. dialog, 3. action, and 4. public opinion) in digital campaigns and online platforms. Then, in the last part, we are going to map those in a real case study in order to further clarify the arguments and show how social campaigns on online platforms contribute to the formation of a public sphere in the digital era.
