Positive organizational behavior seeks to improve individual and organizational performance by understanding and strengthening the positive characteristics of employees, as well as by identifying, investing and developing the strengths of human resources. In this regard, the aim of the present study is to investigate the relationship between positive organizational behavior and organizational performance among elementary school teachers in Sarein. The present research method is descriptive and correlational. The validity of the questionnaire has been confirmed based on the opinions of experts and university professors. Our statistical population includes all the teachers, managers and principals of Sarein city, numbering 108 people, due to the small number of the population, all people were selected as a sample, and the questionnaire link was sent to the people through Shad virtual space. To collect data, two questionnaires of positive organizational behavior by Luthans et al. (2007) and Hersey and Goldsmith's organizational performance (2003) were used. The reliability of the questionnaires was reported as 0.90 and 0.86 respectively. The results of the analysis show that there is a positive and significant relationship between self-efficacy, resilience and optimism and organizational performance. But there is no significant relationship between hope and organizational performance. The positive behavior of employees is a kind of valuable and useful behavior that people show voluntarily and willingly. Therefore, it seems very important and necessary to study and investigate this kind of behavior in the organization.

Human developmental science is not limited to expressing hypotheses, theorizing and empretical investigation. Metatheories of this science, also, affect result interpretation, and educational applications. The study aimed to examine human developmental science in the light of its existing metatheories. Proportion between metatheories and theories which is the basis for educational policies and instructional applications is one of the requirements for optimal human development. Thus, we used descriptive-analytical method to explain different kinds of human developmental metatheories including split metatheory and processrelational metatheory. Split metatheory depicts the world as aggregates of dichotomous polarities, but process-relational metatheory depicts the world as systems of dynamic, changing and reciprocal part-whole relations. In processrelational metatheory, polarities interpenetrate each other and each pole defines and is defined by the other. Moreover, within this metatheory, the whole is an organized system of parts; each part is defined by its relations to other parts and to the whole. Thus, the whole is not greater than the sum of its parts, but it is different from them. New advancements in developmental science reduced the 300-year-old influence of this metatheory through Cartesian split anomalies, and replaced it with processrelational metatheory.

The present research has aimed to study the role of optimism and buoyancy in teachers’ innovative behavior with flexibility as an intermediary. A descriptive research method of the correlational kind was used, and the statistical population consisted of 1500 primary school teachers in the city of Birjand in the school year 2018-2019, 306 of whom were selected as the sample by means of stratified sampling (based on gender and privilege) and in accordance with Morgan’s table. The optimism and flexibility questionnaire devised by Luthans (2007), the innovative behavior questionnaire devised by Kanter (1988) and Shirom's questionnaire for buoyancy (2004) were used in order to assess variables. The content validity of the questionnaires was confirmed by experts. Using Cronbach's alpha, the coefficient of reliability was shown to be 0.80 for the optimism questionnaire, 0.88 for the innovative behavior questionnaire and 0.72 for the buoyancy questionnaire. Data analysis has been done at descriptive (frequency, mean, and standard deviation) and inferential (Pearson correlation, regression and structural equation model) levels. The results showed that optimism, with a beta of 0.42, and buoyancy, with a beta of 0.61, and flexibility, with a beta of 0.50, predicted innovative behavior, and optimism with a beta of 0.39 and buoyancy with a beta of 0.42 predicted flexibility. As indicated by the findings, flexibility has the intermediary role here.

The aim of the current research was to investigate the role of self-acceptance and mental vitality in relation to psychological needs on optimism and psychological well-being of Tehran students. This research was descriptive and correlational. The statistical population of the research consisted of students of various degrees in universities in Tehran. Considering that the minimum sample size required in structural equation modeling is 200 people, 430 people were selected as a sample. The sampling method was available electronically due to the restrictions of the coronavirus. Data were analyzed in SPSS24 and LISREL software. The research tools include Chamberlain and Haaga's unconditional acceptance questionnaire, Ryan & Frederick's mental vitality questionnaire, Guardia, Deci & Ryan's basic psychological needs questionnaire, and Scheier & Carver's optimism questionnaire. The findings show that there is a relationship between psychological needs with optimism and psychological well-being with the mediating role of self-acceptance and mental vitality, but the relationship between basic psychological needs and psychological well-being with the mediation of mental vitality was not confirmed. Based on this, if these needs are met, the feeling of self-confidence and self-worth is formed in people, and it causes mental vitality and optimism in people.

The purpose of the present study is to explain the role of psychological assets in religious education. The research method is descriptive-analytic and the results showed that psychological assets and its main components can be the inspiring source to continue religious activity and increases the chance of reaching inner peace, spiritual power to acquire divine attributes. In other words, features of psychological assets facilitate the way of becoming like God -as the goal of religious education- and provide necessary mental power and energy for people at difficulties, limitations, and obstacles to continue their activities. Components of psychological asset and religious education either directly or through a range of component meanings are interrelated; so that 4 components of psychological asset (self-efficiency, hopefulness, optimism, and resilience) can contribute to creating and continuing religious behaviors. As a result, people can prepare themselves to undertake action and achieve perseverance, resilience, and endurance (patience) to reach their goals.

Considering the role of universities in engineering education, it is necessary to study the status of the educational system and its strengths and weaknesses in order to improve the process of engineering education. In this research, the factors affecting the increase of academic years of engineering students and the status of students who do not complete their studies in the authorized years have been investigated. At first, the effective indicators on increasing the academic years of engineering students were identified and prioritized using the AHP technique. The ranking results show the average of basic courses, the average of main courses, the average of general courses, the number of conditional semesters, the average of optional courses and the number of units dropped have the most impact on increasing the academic years of engineering students. Then, a model was provided to predict the increase in academic years according to the educational status of engineering students using an artificial neural network. According to the results of the neural network, the factors of the number of units dropped, the average of the main courses, the average of the basic courses, the number of conditional terms, the duration of marriage and the average of the high school math and physics courses have the greatest impact on increasing academic years. Finally, by comparing the results of AHP method and neural network, the average factors of basic and main courses, the number of conditional terms and the number of units dropped in both methods were identified as the most effective factors that should be paid more attention while studying engineering students.

The main objective of this study was to synthesize the findings of different studies on positive psychology and gain a general understanding about the relationships between the elements of positive psychology, including psychological well-being, optimism, happiness, resilience, and hope, and academic achievement. The study was also to identify and resolve possible contradictory findings about the issue. In line with these objectives, a meta-analysis design was used to conduct this study. The educational resources of this study were selected from all the available articles on the relationships between elements of positive psychology and academic achievement. After establishing inclusion and exclusion criteria, 19 studies were selected as the sample and from these studies, 35 r-type effect sizes were extracted and analyzed using CMA2 software. The results revealed a statistically significant combined effect size for both fixed and random effect models; however, the identified relationships were found to be low. Furthermore, the effect size of the relationships between happiness, hope, optimism, psychological capital and academic achievement was small, and the effect size of the relationship between resilience and academic achievement was moderate. Base on the overall results of this study, it can be concluded that improvement of positive psychology elements can make the education process more enjoyable and can increase individuals' ability to respond to educational challenges in their learning environment more effectively.

Birth and child is associated with pressure and difficulty for the mother, but if this child has a physical or mental disability, it will lead to consequences and reactions. Accordingly, the aim of this study was to investigate the structural pattern of resilience, optimism and life expectancy with posttraumatic growth in mothers with autistic children with the mediating role of religious beliefs.

The present research is of the correlation type. The statistical sample included 225 mothers with autistic children who were selected by purposive and available sampling from educational centers and the Autism Spectrum Children Association in 2019. The tools used in this research were Religious Attitudes Questionnaire (Serajzadeh, 1998), resiliency scale (Conner-Davidson,2003), optimism questionnaire (Scheier-Carrer, 1985), life expectancy Scale (Miller, 1988) and post traumatic growth questionnaire (Tedischi & Calhoun, 1996), and Pearson correlation coefficient, path analysis and bootstrap method were used to analyze the data.

The analysis of the findings showed that the structural model has a good fit and all predictor and mediator variables can predict 0.41 of the dependent variable changes. Thus, religious beliefs mediate the relationship between Resilience and hope and post traumatic growth, but do not mediate the relationship between optimism and post traumatic growth.

According to the findings, it can be said that religious beliefs can mediate the relationship between resilience and life expectancy with post-traumatic growth, but in the relationship between optimism and post-traumatic growth, religious beliefs do not play a mediating role.

The purpose of this study was to determine the effect of learning some basic soccer techniques on perceptual- cognitive skills on the field. Fifty-eight female participants including 45 students of Azad University of Tabriz branch and 13 skilled soccer club players with a mean age of 22. 30 ± 3.08 years old were selected based on the inclusion criteria and then, were purposefully assigned to five groups [cognitive (near) cognitive (far), control and skilled]. The research method was quasi-experimental studies and its design was pretest-retention. First, a field test was performed on all groups. Then, the acquisition phase for the field group and the practice for the laboratory groups began and finally, after a week, a retention test was performed on the groups. Multivariate analysis of variance test was performed to analyze the data using SPSS 21. The level of anticipation and decision-making skills in the field environment in the motor group and the skilled group was significantly higher than the two groups of laboratory tasks. The results of analysis of covariance revealed that the effect of the group was significant at the level of 99% probability (F (53. 4)) = 12. 77. P = 0.001. Eta coefficient = 50). It seems that, practicing basic skills in combination with observational learning leads to a double engagement of the problem-solving process and improves anticipation and decision-making skills

Data analysis has a fundamental role in decision making process and one effective way to do this is through data mining. In the field of health, by performing data mining on patients with acute conditions such as hemodialysis (HD), their future trends can be partially understood which helps to reduce the severity of their complications. Given that recent studies indicate an increased risk of stroke in HD patients, the aim of this study is to investigate a conventional surgical procedure in hemodialysis and its relationship with stroke. The method of the present study is the use of supervised data mining algorithms and with the focus on the "decision tree", which is one of the applied algorithms in the classification of variables and helps to identify the influential factors. The input data included 468 of hemodialysis patients who were studied over a five-year period and consisted of 324 females and 144 males. This study showed that the risk of stroke in patients whose vascular access surgery was performed by catheterization before fistula was 84.21%, while there was no significant relationship between the age of dialysis patients and their stroke, but in addition to catheter implantation, history of blood pressure or diabetes were also linked to stroke.

Hepatitis is a major health problem in the world and is one of the ten leading causes of death in humans. This disease is an important cause of cancer and liver disorders and causes disabilities in people. The aim of this study was to determine the role of optimism in the relationship between social support and treatment adherence of hepatitis patients in Zanjan.

The method of this research was correlational. The statistical population of the study included all patients with hepatitis referred to the Comprehensive Health Center No. 5 in Zanjan in the first half of 2019 were 999 people, who 210 patients was selected by accessible randoming in the study. To collect the required data, McLean (1993) Ambiguity Tolerance Questionnaire, Sherborne & Stewart (1991) Social Support Questionnaire and Moriski et al. (2008) treatment adherence questionnaire were used to collect the required data. Also, Pearson statistical tests and multiple regression in Spss software version 25 were used to analyze the data. Significance level was considered 0.05 for all tests.

The results showed between social support with treatment adherence (P<0.001, r= 0.360), between social support with optimism (P<0.001, r= 0.329) and also between optimism. There was a direct and significant correlation with treatment (P <0.001, r= 0.349). The results also showed that the effect of total social support on optimism was significant (P<0.001, β= 0.442). The partial mediating role of optimism in the relationship between social support and treatment adherence was significant (P<0.05).

In general, the results of this study showed that social support with partial mediation of optimism was significantly associated with treatment adherence of hepatitis patients.

Marriage as the first step in forming a family institution means combining two perspectives and values. This study was conducted to construct and validate an appropriate scale for measuring the attitudes of martyrs' wives to marriage.

This applied research utilized a descriptive-survey of factor analysis method. The statistical population of the study includes all the wives of the martyrs in the police force (about 300 people), 81 of whom were randomly selected as a sample. The tool of this research was a researcher-made questionnaire that has three sections "cognitive, behavioral and emotional". The face and content validity of the questionnaire was evaluated by some professors and psychologists and they were approved by CVR and CVI formulas. Finally, the questionnaire consisted of 33 questions that were administered to 30 people in the target population, its reliability was estimated by internal consistency method and Cronbach's alpha formula, which indicated its appropriate reliability.

Factor analysis and Varimax method were used to analyze the research. The results of the study showed the existence of seven factors: "evaluation, optimism, pessimism, publicity, desire to have a supervisor, negative perception of fate and fear of loneliness."

This scale is a valid and reliable tool for measuring the attitudes of the martyrs' esteemed wives towards remarriage and can use its results to counsel their marriages.

The aim of this study is to investigate the relationship of religious orientation variables and mental health symptoms with the mediation of optimism, regarding the purpose and use and considering the nature and technique, the descriptive research method of a correlation type. This study considers the religious orientation variable which is a predictor of mental health and optimism as a mediating variable of the relationship between these two variables. The statistical population of the study includes all female students studying in public, non-governmental and nonprofit universities, Islamic Azad and Payamnoor academic centers of Qazvin in the academic year 2014-2014, the sample consists of 380 women selected through stratified random sampling. Optimism, general health and religious orientation were investigated by using the Life Orientation Questionnaire (LOT-R), Mental Health Questionnaire (GHQ) and Alport Religious Orientation, respectively. The reliability of the questionnaires was calculated and confirmed by Cronbach's alpha, 0.85, 0.79 and 0.83, respectively. The data were statistically processed by using Pearson correlation coefficient and structural equation modeling (SEM). The results show that there is a significant positive relationship between internal religious orientation and optimism, and there is significant negative relationship between internal religious orientation and mental health components it is also found that the only way to attain religious orientation is by indirect methods only indirectly through optimism that reduces anxiety, depression and somatization. It is worth noticing that religious orientation does not affect mental health decline by direct method, but through raising level of optimism that contributes to reducing anxiety, depression, and somatization.

The purpose of this study was to investigate the role of attachment to God and spiritual health in predicting optimism in male and female students. The descriptive method was correlation. The statistical population consisted of all high school students in Jolfa city in 2014-2015, out of which 200 were selected by multistage cluster random sampling. The instruments included questionnaires of attachment to God, spiritual health and optimism which were analyzed using Pearson correlation coefficient and multiple regression analysis. The results of Pearson correlation coefficient showed that optimism was positively and significantly related to overall spiritual health score, but it is inversely related to avoiding intimacy with God and the fear of being excluded from the attachment to God. The results of regression analysis also showed that 54% of the variance of optimism is explained by spiritual health and avoiding intimacy and anxiety of rejecting attachment to God.

The main purpose of this study was to validate leadership worldview scale for public schools principals. This scale is a short form of leadership worldview scale (Torkzadeh and Jafari, 2012) and consists of 30 items with a Likert spectrum which is developed in accordance with the Wexler Leadership worldview framework (2006), and includes four subscales: entrepreneurial, network, social and regulatory leadership worldview. Furthermore, each of these four types of leadership worldviews has dimensions including the type of rationality, creativity, patterns of time, change, ethics and leadership style. The statistical population included all primary and secondary school teachers in Shiraz which 369 people were selected by random-stratified sampling method and Cochran’s formula. In order to measure the validity of the questionnaire, two methods of cluster analysis and the first order and second order confirmatory factor analysis were used and Cronbach's alpha method was used to measure its reliability. The results of the item analysis indicated that each subscale had a significant correlation with the type of leadership worldview. The result of the first and second order confirmatory factor showed that each subscale had a high degree of validity for explaining the type of leadership worldview. Also, based on the Cronbach's alpha, the reliability of the scale and the corresponding subscales is desirable. Overall, results approved the applicability of the present scale in the subject area.
