Purpose: STEAM is the term given to a growing field of research and practice that integrates arts and social sciences into traditional sciences, technology, engineering, and mathematics subjects. The purpose of this study is to develop a STEAM-based educational learning package of social sciences textbooks and investigate its effect on the attitude, problem-solving ability, and creativity of sixth-grade primary school students of Bushehr in Iran. The design thinking model was used to design the training package. Methodology: The present study was quantitative applied research. The research design is quasi-experimental with pre-test and post-test with the experimental and control group (unequal control group). The statistical population of this study included all students studying in the sixth grades of public primary schools in Busher in the academic year 2020-2021. Due to the nature of the research which is quasi-experimental and also with respect to the subject drop, 44 participants were considered as the statistical sample (22 students in each group) and they were selected by "accessible" purposeful sampling and randomly divided into experimental and control groups. The STEAM training package was designed in 13 sessions and each training session took a 35-minute duration in the form of 14 projects, and its implementation lasted for 2 months. In order to design each social science lesson project, a focus group meeting was held with the members. Data were collected based on three questionnaires: Hepner and Kruskal's problem-solving skills test, Shaffer's creative attitude survey, and Aiken's scientific attitude test. The face validity of the educational package was confirmed using experts' opinions. In order to check the hypotheses of this research, covariance analysis was used. Findings: The presuppositions of the statistical test of covariance analysis, including the Kolmogorov- Smirnov test for the normality of the research variables and Levin's test for the homogeneity of the variances of the educational variables were confirmed. After that, the effects of the implementation of the steam-based educational package were investigated, and the results of the covariance analysis showed that the implementation of the educational package had an effect of (0.94) on creativity and problem-solving (0.90), and attitude (0.97) on students. The results of the Kolmogorov-Smirnov test showed that the creativity, attitude, and problem-solving skills variables of students have a normal distribution (p> 0.05). The results of the Levin test indicate that these assumptions are confirmed (p> 0.05). Conclusion: Based on the findings, it can be concluded that the STEAM-based training package increases problem-solving ability, creativity, and a positive attitude towards the course of social sciences.

Purpose: Today, the quality of training plays an important role in improving the performance of organizations. Therefore, the current research was conducted with the aim of determining the effect of individual learning on improving the quality of training of the staff of Eghtesad Novin Bank. Methodology: This research in terms of purpose was applied and in terms of implementation method was descriptive from type of correlation. The research population was all the staff of Eghtesad Novin Bank of Tehran city with number 937 people. The sample size based on the Krejcie and Morgan table was determined 272 people who were selected by cluster random sampling method. The research tool was researcher-made questionnaires of individual learning (8 questions) and quality of training (23 questions), which its face validity was confirmed by the opinion of experts and its reliability was estimated above 0.70 by Cronbach's alpha method. Data were analyzed by exploratory factor analysis and structural equation modeling in SPSS and LISREL software. Findings: The findings showed that the factor loading of all items was above 0.40 and individual learning had two components of intrapersonal factors and interpersonal factors and the quality of training had only one component. The average variance extracted of the components was above 0.50 and their reliability was above 0.80 by Cronbach alpha and combined methods. Also, the model of the effect of individual learning on improving the quality of training of the staff of Eghtesad Novin Bank had a good fit and individual learning had a positive and significant effect on the quality of training (P<0.001). Conclusion: Considering the effect of individual learning on the improvement the quality of training of the staff of Eghtesad Novin Bank, the planners of this bank can improve the quality of training through individual training and learning.

Purpose: Today, with the transition from the industrial economy to a knowledge-based economy, the economic value of the human resource in the organization is more evident than ever. Human resource accounting is a relatively new approach to calculating the value of human resources as a part of the organization's capital and assets. This study aimed to identify the components of human resources valuation and design the employee valuation pattern in the country's banking network based on the human resources accounting approach. Methodology: The study was conducted using a mixed method (qualitative and quantitative) in three consecutive phases. In the first phase, the components affecting the human resources valuation process were extracted through the content analysis of related studies. After extracting the general components, initial interview questions were formulated using them. In the second phase, additional components and indicators were identified through semi-structured interviews with elites and informants in human resource accounting. In the third phase, using quantitative methods, the validation and ranking of the components were done. Finally, the valuation pattern of the country's banking network employees was formed. Findings: The final pattern included a total of 36 components in four categories: individual and personality characteristics (11 components), professional qualifications (9 components), social capabilities (7 components), and organizational costs (9 components). Conclusion: The proposed pattern in this study can provide the possibility of a multi-faceted valuation of the banking network employees in Iran due to the coverage of a wide range of components affecting the valuation.

The emergence of celebrities dates back to the mid-19th century, with some scholars tracing their origins to even earlier periods. However, it was the commercialization of the Internet in the 1990s, and more significantly, the rise of the social media industry in the mid-2010s that gave birth to what is now commonly referred to as the "celebrity industry." This industry has experienced a continuous upward trajectory ever since. While individuals with a discerning outlook may perceive celebrities, especially microcelebrities, as superficial and lacking in merit for societal attention, it is essential to recognize their pivotal role in reshaping global economic dynamics. This paper aims to elucidate the undeniable influence of celebrities, particularly microcelebrities, in stimulating ordinary individuals to allocate their hard-earned resources toward non-essential expenditures. Indeed, as the concept of 'consumption' itself has evolved into a potent driving force, celebrities' impact transcends economic domains, extending into the realms of society, personal life, culture, and even politics. This paper endeavors to elucidate the multifaceted consequences of this phenomenon.
