ABSTRACT: One of the important subjects which relate to workforce in Iran is the high ratio of inactive population to the active people in the country so that it is followed by reduced rate of participation. Among the significant factors that effect on this reduced participation is lesser activity of women in outdoor economic and social affairs; and on the other hand, responsibility for rearing children and handling of housework reduces accessibility to high level professions among females and limits the time that they spend for the given occupation and job. This has decreased the opportunity for females’ advancement in several occupational levels and led to their employment at lower ranks. The present study is intended to identify the relationship among four variables: Education degree, social- economic position, rate of work background as well as employment and non- employment of mothers and employed women together with consequences of their employment from men’s attitude. To conduct this investigation, some theories have been adopted including pragmatic (functionalist) theories concerning this point that females’ employment may create occupational competition with husband, radical and liberal feminist theories that are argued about lack of work division in home and exertion of double spiritual- mental stress on women as well as socialist theories of feminists, who believe in that women’s employment has never led to their economic independence. In this study, statistical population includes married male employees with their employed wives and husbands of women, who are employed in Chehardangeh County (Islamshahr city) Education Department, have been tested in two employed groups with education higher than bachelor’s degree as well as employees with education at associate’s degree and lower. In this study, independent variable included: Educational degree of females in statistical population, women’s employment records, their socio-economic position and service records of their mothers. Parameters of variables in this research comprise of occupational competition, work division, self- confidence, stress, and disorder in familial roles, their ideas about girls’ education, economic independence and rate of emotional- feeling relations. Findings of this study indicated that among participants’ occupational- individual characteristics, variable socio- economic position and employment status of mothers of employed women might affect on rate of disorder and interruption in familial roles of employed women. Similarly, education in employed women may improve self- confidence among them and mothers’ employment also affects positively on enhancement the education level in their girls.

ABSTRACT: Measure of Prosocial Moral Reasoning (PROM-R) assesses 5 types of prosocial moral reasoning. Besides considering measurement model with 5 latent variables, other different factor models for this measure can be considered. The present study was designed for examining validity and studying these measurement models on Iranian. PROM-R was administered on 438 Iranian undergraduate students, also two measures for assessing empathy and social desirability was administered on 182 persons of them. Confirmatory factor analysis showed that 5 factors model has better fitness than 4, 3, and 2 factors models. Convergent and divergent validity of PROM-R’ subscales by empathy and social desirability was good. Internalized reasoning and overall score of prosocial moral reasoning had significant and positive relationship to empathy. But any of subscales or overall score hadn’t any significant relationship to social desirability. Also the reliability of PROM-R’s subscales that studied by internal consistency and test re test method was good. The gender differences study showed that males had higher score in the lie/nonsense and approval oriented subscales. But females had higher score in internalized moral reasoning and overall score of prosocial reasoning.

ABSTRACT: Molavi's viewpoint about death and the universe behind it is important, because of having heritage of philosophic and theosophical issues from antecedents. Molavi has noticed to death awareness and also to think about death. About death, he has noticed to being real (being right), generality and death signs. About thinking to death, referring to Prophets as a cause for thinking to death, he has noticed that what should be bogeyman for death is not the death, itself, it is human's deed which sweetens and embitters the universe behind death. Unlike to general conception; Molavi doesn’t realize that death is a natural process, and believes that after dying human returns to his own original place, then there doesn't remain any reason to scare from death, also the wise man hastens toward death instead of escaping from it. Molavi is looking for a way to enter the death universe and universe behind it, to figure its secrets out and back to this world with open results to build a favorite life. To achieve this goal, he makes a similarity between death and asleep and by analyzing it, tries to get this goal from asleep, but since he realizes that asleep is imperfect death and consequently is can't lead to this goal completely, he proposes lethargy (or voluntary death) to enter the death universe and universe behind it.

ABSTRACT: This study is aimed at investigating the relationship between self-efficacy, cognitive and metacognitive strategies, and academic self-handicapping with academic achievement in male high school students in the tribes of Fars province, Iran. For research, a descriptive, correlational method has been used. The population of this study was male high school students in the tribes of Fars province studying in the academic year of 2010-2011. A sample of 322 students was selected by means of cluster sampling.  The instruments utilized in this study included the self-efficacy questionnaire developed by Schwarzer and Jerusalem, the cognitive and metacognitive strategies questionnaire developed by Vahedi, and the self-handicapping questionnaire developed by Jones and Rhodewalt. The data gathered in this research were analyzed by means of descriptive statistics (mean, frequency, and standard deviation) and inferential statistics (Pearson correlation coefficient, regression, one-way ANOVA, Scheffe test, and the Kolmogorov-Smirnov test). The findings revealed that there was a significantly positive relationship between self-efficacy and academic achievement. Furthermore, there was a significantly positive association between cognitive and metacognitive strategies and academic achievement. In addition, there was a significantly negative relationship between academic self-handicapping and academic achievement. The results of the regression analysis showed that academic self-handicapping and academic self-efficacy are significant predictors of academic achievement, and cognitive and metacognitive strategies are not good predictors of academic achievement. Moreover, the results of this research demonstrated that different groups of students - students had different fields of study and were in different grades – were not significantly different with regard to academic self-efficacy, academic self-handicapping, and cognitive and metacognitive strategies. However, there was significant differences in employing metacognitive strategies with regard to students’ grades and fields of study.

ABSTRACT: In this research, relation between Earning Response Coefficient and financial leverage are  evaluated. The main purpose in this research, evaluation of abnormal return influence from unexpected profit when profits are declared and according to company`s financial leverage. Measurement criterions of financial leverage are classified into 2 groups: 1. Income approach, 2.Balance sheet approach But in this survey Balance sheet approach is used. Due to different opinions about use of book and market approaches in calculating financial leverage, in this survey both approaches are used. According to this explanation we will have: 1. Ratio of liabilities to total of assets (book value) 2. Ratio of liabilities to (market value of equity + book value of liabilities). Total assets show company`s book value and (market value of equity + book value of liabilities) show company`s market value. Study on the only hypothesis research with help of Regression`s analysis according to 2 approaches, book and market value, during 2004-2010 shows that financial leverage has no significant effect on abnormal returns . In fact, level of leverage and capital structure of companies has no effect on the reaction of Investors and analysts to release Good and Bad news.
