This study's goal is to evaluate the financial resilience of Bangladesh's ceramics industry using the Altman Z-Score model. The nation's economy heavily depends on the ceramics industry, which also creates jobs and contributes to industrial output. Rapid expansion in both home and international markets makes the financial stability of the sector essential to the stability of the economy as a whole. Using a quantitative methodology, this study examines information from the fiscal years 2020–21 annual reports of five listed ceramics companies. For the first time in this industry context, the Altman Z-Score model reveals a significant portion of companies falling into the "Distress" zone, indicating a heightened risk of financial challenges. The results have real-world ramifications for investors, legislators, and stakeholders. They can be used to improve financial plans and encourage the expansion of sustainable industries. By addressing a significant void in the assessment of financial resilience within Bangladesh's ceramics industry, the study adds to the body of literature.

This study examined the extent to which stock returns can be explained by fundamental financial information. To this end, the accuracy of predicting future stock returns under conditions of mispricing stocks, including underpriced and overpriced stocks, was evaluated. The empirical results are based on a sample of 140 companies listed on the Tehran Stock Exchange during 2006-2022. The applied methodology is based on multivariate regression analysis of panel data. In particular, the six-factor models of Fama-French (2018), Nichols-Wallen-Wyland (2017), and Rhodes croft-Robinson-Viswanathan (2005) have been calculated to investigate the extent of explaining future stock valuation and returns. The results show that most of the changes in the stock valuation of the investigated companies are explained by using fundamental financial factors. Specifically, the results indicate that undervalued companies have earned higher stock returns in the coming year compared to overvalued companies. In other words, in undervalued companies, the stock return has increased in the following year, and in overvalued companies, the future stock return has decreased. According to the provided results, investors and stock exchange regulatory bodies are advised to more sensitively examine companies that have a lower rating of incorrect stock valuation based on the models introduced in this research.

Purpose: Ambivalence includes the ability to perform exploitative activities (attention to the present time) and exploratory activities (attention to the future time) at the same time. Therefore, the current research was conducted with the aim of drawing a scientific map of the field of ambidextrous leadership with a bibliometric approach. Methodology: This research in terms of purpose was applied and in terms of execution method was descriptive. The population of this study was conducted researches in the field of ambidextrous leadership in the Scopus database from 2007 to 2023 with a systematic method. For data analysis was used from bibliometric method with the two objectives of functional analysis and citation network analysis and with PRISMA protocol in VOSVIEWR software. Findings: The results of functional analysis showed that in the field of ambidextrous leadership, Rosing et al had the most citations (583 items) with an article entitled Explaining the heterogeneity of the leadership-innovation relationship: Ambidextrous leadership. Also, the countries of China, Australia, Germany, England and America respectively had the most research in the field of ambidextrous leadership. In addition, the findings of the citation network analysis showed that there were three clusters for authors and six clusters for countries in the co-citation pattern. Also, the synonymy pattern had 1309 links, 337 keywords and 48 clusters, which most of them were with the keywords of innovation, creativity and leadership. Conclusion: The findings of this study about the ambidextrous leadership with a bibliometric approach indicate that the results of this study can help to understand the different angles of ambidextrous leadership with the aim of increasing and promoting it.

Purpose: Individuals going through adolescence faced a significant number of changes from biological, and cognitive to social and emotional. Due to the changes experienced by adolescents, it is susceptible for adolescents to experience a high level of loneliness. The correlation between loneliness and impulsivity and the association between impulsivity and self-harm as well as self-injurious behaviors puts adolescents in a vulnerable position in performing undesirable acts or behaviors. On the other hand, resilience plays a significant role in an individual’s ability to cope with an adverse situation or bounce back quickly after the undesired situation in order to maintain or regain mental health. Therefore, the objective of this study is to run review research through contemporary studies to summarize accumulative documents in the area of resilience, loneliness, and impulsivity among adolescents to investigate the mediating role of resilience. Methodology: For this, a search was carried out on the Web of Science, Google Scholar, and PubMed. Thus, a set of keywords was used, followed by filtering main keywords, resulting in a review of 99 articles published a decade ago. Findings: The results demonstrated that the number of adolescents having mental illness increased significantly over the years, and adolescents aged 16 and above are at risk of mental disorders. Besides that, this research revealed that adolescents in Malaysia are at risk of peer and social rejection, which is highly associated with loneliness and also has a correlation with aggression and impulsivity. Conclusion: It was seen that loneliness and impulsivity are essential risk factors for adolescents’ mental health and resilience can consider effective cognitive and coping skills for adolescents. It was also perceived that most of the papers focus on the investigation of the correlation between loneliness, impulsivity, and resilience, being necessary to develop more experimental studies on the effectiveness of resilience therapy for adolescents’ enrichment. These results serve as a source of reference for future research.
