Premenstrual syndrome is one of the commonest disorders among women with premenstrual period. The aim of the present study was to determine the relationship of anger and fatigue with family functions among women with premenstrual syndrome. The research sample consisted of 120 women who were selected among women with premenstrual syndrome in Ardabil, Iran. To collect the data, State-Trait Anger Expression Inventory-2, Fatigue Scale, Family Assessment Scale, and Daily Symptom Rating Form were used. The results showed that anger and fatigue are significantly related to family functions in women. The results of multiple regression showed that anger and fatigue explained 42 percent of variance family functions of women. Also results support the role of anger and fatigue on family functions. The results have important implications about prevention and counseling in women with premenstrual syndrome. The findings indicate that clinicians should use psychological trainings to cope with the consequences and symptoms of premenstrual syndrome.

This research examined the relationship between video games and cognitive skills including critical thinking and creative thinking. This was an analytical and cross-sectional study. The population of the present research consisted of high school students of Ardebil in the academic year 2013-2014. A sample consisting of 105 students, (54 female and 51 male), was selected using multi-stage cluster sampling. They filled out two questionnaires, namely the California Critical Thinking Skill Test (CCTST) and Critical Thinking Test (CT). The data collected from the questionnaires were analyzed by SPSS through one-way analysis of variance (ANOVA) as well as the Scheffe test. To conduct the analysis, the participants were divided into four groups based on the number of hours spent playing video games every day, namely no gaming, less than 1 hour, between 1-2 hours, and more than 2 hours of gaming; they were also divided into four groups based on the number of years they had been playing video games, namely no gaming, less than a year, 1-2 years, and more than 2 years. The results of the one-way ANOVA revealed significant differences in creativity between the four groups based on the hours spent playing and the number of years the subjects had been playing video games (P<0.05). The differences between the four groups in terms of critical thinking were also significant (P<0.05). The findings indicated that the individuals spending up to two hours playing video games on a daily basis had higher levels of creativity and critical thinking compared to non-gamers.

Purpose: This study aimed to examine the role of informal learning and the organizational learning capacity in learning motivation and professional ethics of faculty members in the Eastern Azerbaijan ′s Universities. Methodology: It used survey approach. Statistical population included 2500 individuals of faculty members in Eastern Azerbaijan from which 400 people were selected using random sampling. Data was collected using four standard questionnaires. To analyze data and examine the relationships of the variables, correlation method and stepwise regression were used. Findings: Results showed a positive and significant correlation between informal learning variables and learning motivation and professional ethics. Also, a positive and significant correlation was found between organizational learning capacity, learning motivation, and professional ethics. Maximum correlation coefficient belonged to informal learning and learning motivation (r=0.73). Based on the findings, the regression model for predicting learning motivation and professional ethics through informal learning and learning capacity is significant. Conclusion: Regarding the findings, it can be concluded that any increase in informal learning and organizational learning capacity is associated with increased academic motivation and professional ethics; hence, attention to informal learning and learning capacity in East Azarbaijan universities It can be of great importance in increasing the learning motivation and professional ethics of the faculty members of the universities of East Azarbaijan.

Purpose: The main of this research was to calculate the efficiency of 9th grade high school female students as well as educational process development to increase the math literacy. Methodology: This educational process is done by combining realistic mathematics education and the process of solving mathematical problems by quasi-experimental method. The statistical population of the study was 242 ninth grade students in district 19 of Tehran province in the 98-99 academic year; they were divided into two groups of 122 students as experimental group (A, B) and 122 students as control group (C, D). The data analysis method was based on Data Envelopment Analysis (DEA). The output-oriented Charles, Cooper, and Rhodes (CCR) model was used for determining the efficiency of the students. Findings: Each student was considered as a decision-making unit (DMU) in which inputs were mathematical pre-test scores and outputs were the mathematical post-test scores. 91.185% of class A students and 93.6% of class B students from the experimental group were efficient, which has much better offspring than the control group. Conclusion: The results showed that the students involved in problem solving and realistic math instruction were efficient and the Pisa test performed very well. In addition, data envelopment analysis was a suitable method for evaluating and analyzing students' annual performance.

Purpose: This study uses TAM theory to better understand variables that are indicative of MOOCs’ courses’ completion rates; furthermore, this paper scrutinizes the quantitative relationship between MOOC platform usage and learning satisfaction. Methodology: This was an applied research in a virtual community called Coursera where people all over the world participate. The research design was quantitative and the questionnaire link was posted on the Coursera, with convenience sampling. Data collection process started from November 12, 2020 until February 23, 2021, and 234 users of the selected MOOC platform (Coursera) participated to evaluate the proposed model. A multivariable systematic technique (PLS) was applied to analyze the model. To conduct the reliability test, individual item loadings and internal consistency were consulted. Convergent validity of the model was measured via the Structural Equation Model (SEM). The examination of the SEM was incorporated an evaluation of the path coefficients and R2 values. Findings: The loadings of all measurement items are larger than 0.792, indicating sound internal reliability of the dataset. Moreover, the Cronbach's alpha values are all > 0.7 which proves the internal consistency of the research model. In this research, the range of CR is 0.838 to 0.947 and the range of AVEs 0.634–0.857, both exceeding the threshold values for desirable convergent validity. To obtain discriminant validity, the square root of AVE should be larger than the correlation among the constructs. The value of each AVE’s square root is greater than the off-diagonal components. The model explains 21.1% of the variance in perceived usefulness, 20.9% in perceived ease of use, 26.9% in attitude to use, 20.0% in MOOC platform actual usage and 24.2% of the variance in learning satisfaction. The path coefficient from quantity and quality of knowledge (β=0.261, p<0.01) and perceived feedback (β=0.215, p<0.01) to PU are positive. The results show that perceived feedback (β=0.275, p<0.01), perceived complexity (β=-0.367, p<0.01) significantly and meaningfully affect PEOU. The PU showed a positive and strong effect on attitude to use (β=0.271, p<0.01), MOOC platform actual usage (β=0.360, p<0.01), and learning satisfaction (β=0.277, p<0.01). Conclusion: The results indicated that the quantity and quality of the knowledge and perceived feedback have a positive and significant impact on the perceived usefulness of MOOCs. The perceived complexity as a negative construct was found to be an important indicator of MOOC platforms usage.

Purpose: The present research was performed to design interactive model of digital marketing in the area of online service startups based on mobile commerce in modern sociology. Methodology: This study was of fundamental type regarding the objective, and combined type regarding the method of implementation (qualitative and quantitative). The research population consisted of experts familiar with the issue in Hormozgan province in 2020, out of whom 20 were chosen as the sample through purposeful sampling method as the sample.
