Tour guides are considered as one of the key players within the tourism supply chain, serving as direct interfaces with visitors and acting as cultural mediators between diverse cultures. They exert a significant influence on tourists' intentions for repeat visits. Nowadays, tourists are not merely seeking basic information from guides, as they can easily access such information online. Instead, they are in search of creative, authentic, interactive experiences with participatory learning, demanding the presence of creativity in tour guides. Consequently, guides need to demonstrate new forms of creativity in their performance. Creativity is a pivotal aspect for achieving professional success in the realm of tour guiding. The depth of their professional knowledge and their creative abilities significantly impact the quality of tours and the portrayal of destinations. As cultural intelligence is one of the critical dimensions of creativity, this research aims to explore the relationship between cultural intelligence and the creativity of tour guides. Using a library review method, it examines the role of cultural intelligence, its dimensions, and indicators. Ultimately, it presents a conceptual framework for fostering the creativity of tour guides, grounded in the principles of cultural intelligence.

Purpose: Considering the importance of cancer in human societies and its negative effects on human body and psyche, the aim of this study was to compare the efficacy of Acceptance and Commitment Therapy and Schema Therapy on resiliency of breast cancer patients in East Tehran Medical Centers. Methodology: This study is a pilot study with single stage cluster sampling method. We selected 150 patients with breast cancer in East of Tehran. The Connor-Davidson Resiliency Questionnaire was presented. Forty-five subjects were randomly selected and divided into three groups of 15, consisting of two interventions and one control group, 12 sessions of group schema therapy and 12 sessions of acceptance-based therapy, each session lasting 90 minutes. Each intervention was performed twice a week for 3 days. At the end of treatment all three groups were tested. Findings: The finding showed that there is a significant difference between the experimental group under the influence of Acceptance and Commitment Therapy and Schema Therapy in post-test resiliency. F (1.41) = 530/35. Conclusion: The results showed that schema therapy is more effective on resiliency than, Commitment-Based and Acceptance.

After closing, the multi-period portfolio can be corrected and revised at regular intervals. The philosophy behind using multi-period portfolio models is that investors often have a multi-period view of future changes in assets, which can be the result of technical and fundamental analysis or statistical model analysis. In conventional multi-period portfolio models, it is assumed that the forecast and correction time horizons are the same for all assets. However, one asset may be forecasted over a one-month horizon while another may be forecasted over a two-month horizon, and both may be revised in the future. The purpose of this study is to present a multi-period portfolio model in which assets have different time horizons for corrections or an asset may not be traded for the first few periods and then enter the correction stage. In this model, fuzzy variables defined in a credibility space are used to describe the return, and the credibility measure controls the risk. The model's objective function is to maximize the portfolio's ultimate wealth, and a constraint is used to control portfolio risk, in which the validity of the portfolio's ultimate wealth below a certain threshold is controlled at a certain level of confidence. A combination of particle swarm optimization and simulation is used to find the best solution. Finally, using a numerical example, the model is implemented on a portfolio with 6 assets and 4 monthly time steps on the Tehran Stock Exchange.
