The competitiveness of tourist destinations has a good place in the literature and theoretical foundations of tourism studies, however, in the field of research it is full of inconsistencies and contradictions in terms of concept, measurement and legitimacy. The purpose of this study was to provide a holistic and systematic view of studies in the field of competitiveness of tourism destinations and analysis of previous research in the hierarchy of the scientific paradigm of this field of tourism studies. Therefore, in order to create a deeper understanding of the characteristics, factors and how to measure and improve the competitiveness of tourism destinations, a qualitative meta-analysis method was used to collect and analyze previous researches and Blaikie Triple Index was used to analyze these researches in the hierarchy of the scientific paradigm of tourism competitiveness studies. The results show that in the last two decades, much attention has been paid to the research of tourism destinations competitiveness and to overcome the complexities of this field of tourism studies, researchers have sought to integrate previous models in order to come up with new findings. Other results of this study, which distinguish it from other studies, show that in the hierarchy of the scientific paradigm of this field of tourism studies, 61% of previous studies, after answering the question of what (epistemology), have addressed the issue of why (ontology). Also, a small number of studies related to the competitiveness of tourism destinations (15%) have tried to provide a new model for how to measure the competitiveness of tourist destinations by going through the two levels of what and why (methodology). The final finding of this research is to provide a conceptual framework in which the interaction of factors and variables of competitiveness of tourist destinations with a systemic and holistic perspective is specified.

Sustainable tourism development planning based on the existing potentials in any region of the country is an obvious necessity. Considering the adoption of a government development approach to Semnan province in recent years, this province can be considered as a good case to study. The east of the province, despite its high potential for tourism development as well as its geographical area, has received less attention. The purpose of this study is to identify the most important sustainable tourism projects in the east of Semnan province. For this purpose, applied, descriptive (non-experimental) and combined (qualitative-quantitative) research can be pursued. First, a focus group (qualitative method) consisting of 12 experts including officials, university professors and local people was used to identify the projects. After that, 30 output projects were ranked according to the degree of compliance with the criteria of sustainable development and the goals defined in the upstream documents using the Analytic Hierarchy Process (AHP) (quantitative method). According to the ranking, training the local people of the region, providing the necessary infrastructure in the sample areas and target villages, and determining appropriate marketing methods and preparing an advertising plan for tourism development in the region are of priority.

Land use management is one of the important axes of sustainable development, resource conservation and proper use of resources. The purpose of this article is to investigate the role of local managers in land use management and prevent informal land use change in rural areas of Khoramdareh Township. The research method is descriptive-analytical and data collection has been done using documentary and field studies. The statistical population is the villages of Khoramdareh Township with a population of 12582 people, of which 373 individuals were evaluated by Morgan table sampling method. Regression analysis was used for data analysis using ERDAS and SPSS software. During the study period (1969 to 2013), 1721.6 hectares of land in Khoramdareh Township has undergone land use change. During this period, 176 hectares have been converted to industrial use and 1545 hectares to agricultural use. The satisfaction of the statistical community with the performance of local management in land use management was 0.726; which means that from the statistical community point of view, local management has a direct and high impact on land use management and monitoring of land use change. Among the local management performance indicators, the highest level of satisfaction was with the index of "monitoring rural land use" (β = 0.447) and the lowest level of satisfaction was with the index of "rural economy development (agriculture)" (β = 0.227). In order to have a better land use management, it is necessary to increase supervision, change the use in accordance with the environmental capabilities and prepare the land use cadaster of the region.

Hafez Street in Shiraz, as the axis connecting the Quran Gate to the Isfahan Gate, has lost its visual coherence due to the interventions of recent decades. Therefore, its place in the mental image and perceptual structure of citizens needs to be examined. The purpose of this study is to identify the effect of each of the physical components affecting the visual perception of citizens and to examine the relationship between them. The research method is "survey and correlation" and the required data have been collected through field studies such as photography, mapping and taking notes, as well as questionnaires and documentary studies. The sample size was calculated using the Cochran's formula and the available sampling method was used to complete the questionnaire. Multivariate regression test was used to analyze the data. The results indicate that the "readability" component has the greatest impact on citizens' visual perception, and in the next priorities are the "clarity" and "human scale" components. On the other hand, the "diversity in the environment" has had the least effect on the visual perception of this street. Finally, some strategies were proposed to improve the visual perception of observers in order to improve the performance of existing urban spaces in addition to creating stronger mental images of the city.

Housing is one of the main concerns of governments in countries all over the world. In Iran, after the increasing pace of population growth, various policies were implemented to provide housing. One of the policies implemented in the second half of the 2000s was the Mehr Comprehensive Housing Plan. The purpose of Mehr project was to provide low-income groups with fast, cheap and high-quality housing. The purpose of the present study is to evaluate the quality of life in order to measure the success rate of one of the major projects in Mehr housing neighborhood of Shahinshahr. The present study is applied in terms of purpose and descriptive-analytical in terms of nature. The data were obtained in two ways: library (to formulate theoretical foundations) and field (to study the quality of life in the neighborhood). The statistical population of the study is the residents of Mehr Shahinshahr housing neighborhood with a population of 6400 households. The sample size, estimated by Cochran's method, is equivalent to 400 heads of households. Descriptive statistics, factor analysis and Chi-square test were used to analyze the 40 indicators. The results showed that the average of five indicators was higher than the average of satisfaction. These indicators include: 1- Access to public transportation, 2- Access to water, electricity and gas facilities, 3- Access to heating and cooling facilities inside the complex, 4- Management of the complex and 5- Access to parking. The average satisfaction of other studied indicators (87.5% of the indicators) was less than 3, which indicates the strong dissatisfaction of the residents of Mehr Shahinshahr housing neighborhood with the quality of life in this neighborhood.
