In this paper, a fractional multi- objective multi- product solid transportation problem with interval costs, supply, demand, and conveyances is investigated based on fuzzy programming approach. To minimize the problem, the order relations that represent the decision maker's (DM) performance between interval costs, supply, demand and conveyances are defined by the right limit, and the left limit. Through the deterministic problem is obtained, a fuzzy programming approach is applied by defining membership functions. A linear membership function is being used for obtaining optimal compromise solution. Finally, a numerical example is given to the utility of the approach.

Comprehensive and reliable conceptual definition of concepts can be considered as the first step toward managing the phenomena based on those concepts. Spiritual tourism is a multidimensional phenomenon with different mixed concepts such as spiritual experience, spiritual tourist, achieving spirituality through tourism, deepening and institutionalizing spirituality perception (experience), training and learning spirituality (spiritual experiences), development planning, spiritual tourism economics, and spiritual tourism marketing. The mentioned concepts are formed in dialectical models that are influenced by disciplines such as geography, history, economics, management, religion, and mysticism. Regardless of the level and the type of combination of concepts, the definition of these concepts may be different in various paradigms due to the differences in assumptions, ontology, epistemology and methodology of different paradigms. Such a different even makes the spiritual tourism’s definition process more difficult. Spiritual tourism has already common definitions in literature that are not formally classified based on various paradigms’ assumptions; and have not been specified by the tourists under which paradigm that they are formed. Therefore, in this paper, the concept of spiritual tourism is reviewed from the perspective of different paradigms such as positivism, critical romanticism, post-modernism, critical realism, and pragmatism and new definitions are extracted. Based on the results of this article, the passage from abstract concepts to operational concepts in the field of spiritual tourism has been smoother. Besides, a more sustainable vision has been created about how to create and disseminate knowledge in the field of spiritual tourism. Hence, the main aim and contribution of this article is to extract the different conceptual definitions of spiritual tourism in different paradigms, in order to provide a reliable paradigm conceptual definition of tourism spiritual. The present paper concluded that a reliable and comprehensive definition of spiritual tourism can be provided in Pragmatism Paradigm framework.  This pragmatic definition can be used as a base for future planning, management, marketing, and other operational and administrative applications.

INTRODUCTION: After the approval of the country's crisis management law, the upstream documents related to this law, including the preparedness and response programs at the national and provincial levels, are among the tasks assigned to increase the efficiency of the crisis management processes. METHODS: This study presents a general framework for developing a provincial crisis response program. The proposed process has been used to develop the crisis response program of Hamadan province. In the phase of understanding the current situation, questionnaires and in-depth interviews were used to collect field data and determine the challenges presented to crisis management in Hamadan province. Moreover, a method for allocating the specialized functions of the response phase to the provincial organizations has been presented using the national crisis documents. FINDINGS: In general, the findings of this research can be assigned to three groups. The first group pertained to the project method, including the stages of understanding the current situation and developing the response program of the provinces. The second group of findings was the summary of the analysis of field data collected regarding the state of preparedness and response in Hamadan province. The third group encompassed determining and allocating specialized crisis response functions in Hamadan province. The functions of the provinces (n=32) and after their compliance with the national functions, the crisis management law, and the capabilities of the existing organization in the province, 56 specialized sub-functions were identified in the provinces, and the responsible, collaborating, and supporting institutions were determined. CONCLUSION: As evidenced by the obtained results, in the process of function allocation, some problems have been identified due to the shortage of information in the upstream documents, which are suggested to the crisis management organization for better planning.

Microfinance institutions in India provide a set of financial services to the economically weaker sections. Recently, a large number of microfinance institutions have emerged in India and they have favorable impact for poverty reduction. The impact of these institutions on entrepreneurship and society, needs to be explored in greater depth. The objective of this study is to apply machine learning techniques to explore this impact. The research uses a MIX dataset for three successive years, namely 2017, 2018, and 2019. This dataset comprises eight variables centered on gross loan portfolio. Principal Component Analysis (PCM) has been applied on the sample dataset for dimensionality reduction, resulting in two main components and each component consist of fraction from eight variables. Then, the sample dataset has been labelled with the help of clustering using K-means clustering technique. Further, classification models based on K-Nearest Neighbors (KNN) algorithm and Support Vector Machine (SVM) are applied to predict the appropriate category of entrepreneurship. The experiment result shows that the machine learning techniques have been found effective and useful tools for estimating the impact of microfinance on entrepreneurship in India.
