The purpose of this study was to examine the effect of uncertainty in economic policy on the stock price crash risk. In this applied descriptive-analytical ex post facto study, the statistical population included the companies listed on the Tehran Stock Exchange. Over a seven-year period, 148 companies are selected using the systematic sampling method (2015–2021). In this study, the negative skewness of return on equity (ROE) and down-to-up volatility were used to assess the stock price crash risk (dependent variable) and uncertainty in economic policy (independent variable). The data was then analyzed using the multivariate regression model. The results of the hypothesis testing indicated that volatility in the interest rate, dollar exchange rate, inflation, and economic growth had a positive significant effect on the stock price crash risk or the negative skewness of ROE and down-to-up volatility. Hence, given the effects of macroeconomic variables on the ROE, in order to achieve economic sustainability, the Government of the Islamic Republic of Iran should pay close attention to the adoption of macroeconomic policies, prevent economic policymakers and planners from implementing hasty unscientific policies, and increase the share of tax revenues from income sources.

Background and Aim: It is natural for differences and conflicts to arise between husband and wife. Due to the nature of spouses' activities, it sometimes happens that differences of opinion occur or needs are not met; As a result, spouses feel angry, disappointed and unhappy towards each other. The current research aimed to determine the effectiveness of strength-based counseling on the tendency toward marital infidelity and self-compassion of conflicted couples. Methods: In terms of purpose, the current research was of the applied type and the method of conducting it was quasi-experimental with a pre-test and post-test design with an experimental group and a control group and a three-month follow-up period. The statistical population of the research included all couples referring to a private counseling center in District 10 of Tehran. For sampling, 30 couples were selected and randomly assigned to two experimental groups (15 couples) and a control group (15 couples) using the available sampling method. In this research, the strength-based counseling package compiled by Parsakia & Darbani (2022) was used. Also, in order to collect data, Neff's self-compassion questionnaire (2003) and Bashirpour et al.'s marital infidelity questionnaire (2018) were used. Results: The results of data analysis showed that strength-based counseling significantly increased self-compassion scores (F = 13.08) and decreased the scores of the tendency toward marital infidelity of the experimental group (F = 9.52). Also, Bonferroni's post hoc test results indicated good stability of these effects. Conclusion: Therefore, the strength-based approach can increase the self-compassion of conflicted couples and decrease their tendency toward commit marital infidelity.

Purpose: The integration of visual and verbal modes in educational materials, particularly in school textbooks, plays a chief role in enhancing the learning experience. Thus, the present study aimed to analyze the intersemiotic complementarity of verbal and visual modes in three English school textbooks from two countries with different policies toward English education at public schools, Iran and Malaysia. Methodology: Employing a qualitative descriptive approach, this study analyzes the intersemiotic complementarity within English school textbooks used in the first grade of high school in Iran and Malaysia, focusing on three selected textbooks: Prospect 1 (Iran), Form 1 (Malaysia), and Pulse 2 (Malaysia). The analysis was guided by Royce's (1998) framework for intersemiotic complementarity, with a particular emphasis on the ideational metafunction. This involved examining the coherence between visual representations (images) and textual content (dialogues) to assess how these elements complement each other in conveying educational content and facilitating learning. Findings: The analysis revealed a marked disparity in the integration of visual and verbal modes between the textbooks from the two countries. Iranian textbooks, specifically Prospect 1, demonstrated a significant disconnect between images and text, often leading to confusion and potentially hindering students' learning. In contrast, the Malaysian textbooks (Form 1 and Pulse 2) exhibited a high level of intersemiotic complementarity, with images effectively supporting and enhancing the textual content, thereby facilitating a more cohesive and comprehensible learning experience for students. Conclusion: The study demonstrates the importance of cohesive integration of visual and verbal elements in textbooks to support effective learning, highlighting the need for strategic multimodal design in educational materials. By ensuring a cohesive integration of visual and verbal elements, textbooks can become more effective tools in enhancing comprehension and improving learning outcomes. This research contributes to the growing discourse on multimodal education, suggesting pathways for future investigations into the optimization of textbook design for enhanced educational impact.

Through an epistemological lens, this article asserts that the dawn of the internet of data (IoD) era marks a profound shift in our understanding of human existence, one that challenges the notion of modern man as a singular and distinct entity. Delving deeper, the analysis presents an ontological exploration of the transition from a human-centric approach of the 19th and 20th centuries to the added-value man of the 21st century, examining the ideological underpinnings of concepts such as the Information Society and Society 5.0 respectively as representatives of the above two insights. In particular, the article meticulously dissects the stance of each approach towards humanity, highlighting the paradigm shift in our perception of the human experience. This piece offers an insightful commentary on the evolution of our understanding of human nature, encouraging us to rethink our place in the rapidly changing digital landscape.

It is generally perceived that serious games are more interesting to people who are more educated. But is this perception really true? This paper tries to answer this question and some other related questions to provide a clearer picture of who plays strategic games in the US. Data were taken from a large dataset of one of the PEWs surveys. The American Trends Panel is a probability-based online panel which is carried out nationally using a sample of adults in the United States living in households. This survey was fielded for the Pew Research Center by Abt Associates from April 4 to April 18, 2017. Overall, 4,168 participants completed the Wave 26 survey. The results found that in comparison with non-strategic gamers, strategic gamers are more likely to be men, more educated and wealthier, though the differences are small. It seems the old stereotypes about Sgamers and NSgamers should be re-evaluated, if we want to know how to use serious games for educational purposes.
