This quasi-experimental study investigated the comparative effects of two instructional approaches – cooperative learning and a hybrid model integrating cooperative and competitive elements – on English as a Foreign Language (EFL) learners' writing proficiency. Participants (n = 23) were female EFL learners aged 16 to 45 (Mage = 30.5) selected through convenience sampling and homogenized based on their Preliminary English Test scores. Participants were randomly assigned to one of two experimental groups. Both groups received pre- and post-tests. The experimental groups received instruction using either a cooperative learning approach or a hybrid approach incorporating both cooperative and competitive elements. Repeated Measures ANOVA was employed to analyze the data. Results indicated that the hybrid approach significantly outperformed the cooperative learning approach in enhancing learners' writing complexity, accuracy, and fluency. These findings suggest that integrating competitive elements within a cooperative framework can significantly improve EFL learners' writing proficiency, offering valuable pedagogical implications for educators and materials developers.

This study intends to investigate the ability of Elliott Waves Theory (EWT) to predict the information content of accounting profit before its announcement in companies listed on the Tehran Stock Exchange from 1394 to 1399(Iranian calendar). The present study is applied research in terms of the result’s implementation and to collect the data required for the research, the information site of the publishers of Tehran Stock Exchange and Rahavard Novin software and for receiving Elliot Waves signals Advanced GET software has been used. Earnings information content was measured through the test of the relationship between earnings and abnormal returns based on the Portetti model [20]. In order to calculate the abnormal returns, the Zebrowski comprehensive return relationship was used. Finally, the effect of two variables, company size and type of industry, on the ability to predict information content is considered. The results showed that the quarterly profits announced by companies have information content, and EWT can predict profit information content before announcing it. In this regard, company size and industry type do not affect Elliott Waves’ ability to predict profit information content.

Two policies of carbon tax are considered by many countries for reduce carbon emissions. First policy emphasized on tax and second policy notice subsidy for carbon emission control. The results show that according to conditions, two policies can effective on reducing carbon emissions and technology development. A carbon tax Policy is needed to reduce carbon emissions in logistics systems. The purpose of this paper is to present effect of carbon tax policies for logistics in Iran pulp and paper industry. The research method is descriptive and data collection is survey, Samples consists two groups. The first group are experts for proposing possible Policy and deter-mining evaluation indices and selecting the appropriate Policy. The second group are managers in pulp and paper company for choose an appropriate Policy. Effect of factors on carbon tax was determined by experts’ interviews and fuzzy mean. Two suitable policies that covers the fossil fuels, were selected for simulation by VENSIM software. We considered 10 years for test and 10 years for simulation. Results showed both policies affect pollution reduction, reducing the fossil fuels consumption, reduction of emissions and increase innovation in the logistics system. The second policy that is carrying out carbon tax is more effective than the first policy which paying subsidies to reduce emissions.

Momentum strategies, due to their strong performance, are common investment methods designed based on the continuation of past asset performance. However, these strategies face sharp declines in high volatility conditions and market reversals. In this research, the impact of Constant Volatility Scaled Momentum (cMOM) and Semi-Constant Volatility Scaled Momentum (sMOM) strategies is examined using data from 100 stocks that constitute a significant portion of the Tehran Stock Exchange market value during the years 2013 to 2024. These strategies aim to reduce risk and improve risk-adjusted returns by adjusting for recent volatility. The results show that sMOM outperforms cMOM in factor-spanning tests and acts as a complement to traditional momentum. Moreover, its strong correlation with traditional momentum and its relative independence from market risk were confirmed in this study. These findings indicate that volatility adjustment does not always lead to performance improvement, and market conditions play a crucial role in the efficiency of these strategies. The results demonstrate that neither the constant volatility nor the semi-constant volatility scaled momentum strategies consistently outperform one another.

Objective: The aim of this study was to predict and explain happiness and hope for the future based on parental attachment styles among female university students. Methods and Materials: This research was conducted using a descriptive-analytical and correlational design with a predictive approach. The statistical population included all female students of the Islamic Azad University, Garmsar Branch, during the academic year 2022–2023. A total of 274 students were selected using stratified and purposive sampling methods based on specific inclusion and exclusion criteria. Data were collected using the Oxford Happiness Questionnaire, Snyder’s Hope Scale, and Hazan and Shaver’s Adult Attachment Style Questionnaire. After obtaining informed consent, the data were analyzed through Pearson correlation, multiple regression, and path analysis using SPSS and AMOS software. Statistical significance was set at p < .05. Findings: The results showed that secure attachment style significantly and positively predicted both happiness (β = .38, p < .01; R² = .24) and hope for the future (β = .44, p < .01; R² = .31). Avoidant attachment style was a significant negative predictor of happiness (β = –.29, p < .01) and had a weaker, yet still significant, inverse relationship with hope for the future (β = –.11, p < .01). Ambivalent attachment style negatively and significantly predicted both happiness (β = –.17, p < .01) and hope for the future (β = –.30, p < .01). All regression models met the assumptions of normality, linearity, and independence of residuals. Conclusion: The findings suggest that parental attachment styles, particularly secure attachment, play a meaningful role in promoting positive psychological outcomes such as happiness and hope in emerging adults. Insecure attachment styles, including avoidant and ambivalent, are associated with diminished emotional well-being.

Objective: This study was conducted with the aim of analyzing the phenomenon of divorce from the perspective of expert family therapists. Method: The research method was qualitative, based on grounded theory (Charmaz, 2014). The research setting included all family therapists in the city of Isfahan in the year 2024, and the participants consisted of ten of the most prominent therapists who were purposefully selected. The research tool was interviews conducted in the form of focus groups. The collected data were analyzed using Charmaz’s (2014) method: first, coding was carried out, followed by conceptualization. Then, during the process of integration, categories were extracted, and finally, the core categories were identified and the theory was formed. Results: The results indicated that the phenomenon of divorce includes three main categories: (1) the reasons behind the occurrence of divorce: the activators of divorce causes, with categories such as changes in cultural and social structures and the prioritization of individuality over couplehood; (2) the nature of divorce causes: causes of divorce categorized as changes in family roles and authority, poor spouse selection, inappropriate communication, and individual problems; and (3) the process through which the causes interconnect: integrators of divorce causes (disturbance-power, disturbance-intimacy, and boundary disturbances). Conclusion: Based on the findings, this study suggests that in order to reduce divorce, the activators of divorce cannot be ignored, as they render society more prone to facilitating the grounds for divorce rather than preserving family stability. Additionally, the identified causes of divorce indicate that many revolve around the philosophy of individualism. Therefore, society and societal discourse must reinforce the value of collectivism so that this value can function as a socio-psychological superstructure acting as a barrier to divorce.

Objective: This study aimed to compare the effectiveness of cognitive-behavioral interventions using coaching and self-learning methods on marital satisfaction and couple intimacy. Methods and Materials: This semi-experimental study followed a pre-test–post-test design with a control group and two experimental groups (coaching and self-learning). The statistical population consisted of couples who visited family counseling centers in District 8 of Tehran in 2022 and reported low levels of marital satisfaction and intimacy. A purposive sampling method was used to select 45 participants, who were equally divided into three groups of 15. The coaching group received eight 90-minute cognitive-behavioral sessions, while the self-learning group was given a structured 73-page manual to follow independently over two months. The control group received no intervention. Data were collected using the ENRICH Marital Satisfaction Questionnaire and the Thompson and Walker Marital Intimacy Scale. Analysis of covariance (ANCOVA) and multivariate analysis of covariance (MANCOVA) were used to analyze the results. Findings: ANCOVA results indicated that cognitive-behavioral interventions using the coaching method significantly improved marital satisfaction (η² = 0.30, p < .01) and couple intimacy (η² = 0.372, p < .01), compared to the control group. Similarly, the self-learning method showed significant improvement in marital satisfaction (η² = 0.19, p < .01) and intimacy (η² = 0.23, p < .01), although the effect sizes were smaller. Conclusion: Cognitive-behavioral interventions, particularly through coaching, are effective in enhancing marital satisfaction and intimacy. The presence of a coach facilitates deeper understanding, accountability, and behavioral change, making it a more impactful approach compared to self-directed learning.

Objective: The aim of this study is to examine the strategies and consequences of non-marriage among single men. Methods and Materials: The study was carried out using a qualitative approach and grounded theory methodology. The study population consisted of men whose age ranged between 33 and 45 years, considering the average age of marriage for men in the city of Kazerun in 2023 was 30.9 years. All participants were residents of Kazerun County in Fars Province. Sampling was conducted using purposive sampling based on inclusion/exclusion criteria until theoretical saturation was reached (15 participants). Data were collected through semi-structured interviews and analyzed using Strauss and Corbin's (1998) grounded theory approach, including open, axial, and selective coding. Findings: In the open coding phase, out of 232 identified codes, 33 open codes related to strategies and 56 open codes related to consequences were extracted. These codes were categorized into different concepts during axial coding. Finally, in the selective coding phase, the main categories and related outcomes of non-marriage were identified. The most significant strategies for not pursuing marriage included improving economic conditions, enhancing mental and physical well-being, developing alternative relationships, and seeking emotional or financial bonds. On the other hand, mental and psychological consequences, objective consequences, and environmental consequences were among the major outcomes associated with prolonged singlehood in men. These included negative emotions such as depression, isolation, wasted time and energy, and economic and social problems. Conclusion: This study revealed that the decision not to marry among men is the result of a combination of psychological, social, cultural, and economic factors that influence individual choices. Based on the findings, it is recommended that social and cultural policies aimed at supporting youth and facilitating marriage are essential. Moreover, identifying and thoroughly examining cultural and social barriers to marriage could help reduce the rate of singlehood and increase the willingness to marry among young people.

Objective: This study aimed to investigate the relationship between humor and stress in families, with positive affect as a mediating variable. Methods and Materials: The study employed a descriptive correlational design with 409 participants selected from families in South Africa, based on the Morgan and Krejcie sample size table. Data were collected through standardized questionnaires measuring humor, stress, and positive affect. Pearson correlation analysis was conducted using SPSS-27 to explore bivariate associations among variables. Structural Equation Modeling (SEM) was performed in AMOS-21 to test the hypothesized mediation model. Model fit was evaluated using multiple indices, including χ², df, χ²/df, GFI, AGFI, CFI, TLI, and RMSEA. Findings: The results revealed significant correlations between the study variables. Humor was positively correlated with positive affect (r = 0.53, p < .001) and negatively correlated with stress (r = −0.41, p = .001). Stress showed a significant negative correlation with positive affect (r = −0.47, p < .001). The structural model demonstrated acceptable fit (χ²(61) = 124.36, χ²/df = 2.04, GFI = 0.93, AGFI = 0.90, CFI = 0.96, TLI = 0.95, RMSEA = 0.049). Path analysis confirmed that humor had a direct positive effect on positive affect (β = 0.39, p < .001) and a negative effect on stress (β = −0.34, p = .001). Stress negatively influenced positive affect (β = −0.28, p < .001). Positive affect mediated the relationship between humor and stress, with a significant indirect effect (β = 0.09, p = .002). Conclusion: The findings highlight the protective role of humor in family contexts, showing that it reduces stress both directly and through the mediating role of positive affect. Integrating humor into family-based interventions may enhance resilience and emotional well-being.

Objective: This study aimed to compare the effectiveness of compassion-focused therapy (CFT) and schema therapy on psychological well-being and sense of coherence among infertile women. Methods and Materials: A quasi-experimental, pretest-posttest-follow-up design with a control group was used. Thirty infertile women referring to Saarem Hospital in Tehran during the first half of 2024 were randomly assigned to three groups: CFT (n=10), schema therapy (n=10), and waitlist control (n=10). The CFT group received eight sessions, and the schema therapy group received ten sessions. Psychological well-being was assessed using the 18-item Ryff Psychological Well-Being Scale, and sense of coherence was measured with the Flensborg et al. (2006) Sense of Coherence Questionnaire. Data were analyzed using multivariate analysis of covariance (MANCOVA) and Bonferroni post-hoc tests. Findings: MANCOVA results showed significant differences between groups on both psychological well-being and sense of coherence at posttest (Wilks’ Lambda = .350, F(4,54)=18.76, p<.001). Univariate tests indicated significant group effects on psychological well-being (F(2,27)=18.45, p<.001) and sense of coherence (F(2,27)=22.13, p<.001). Post-hoc analyses revealed that CFT significantly improved psychological well-being compared to schema therapy and control at posttest (p<.05), while schema therapy led to greater improvements in sense of coherence compared to CFT and control (p<.05). Both interventions maintained their effects at the one-month follow-up. Conclusion: The findings suggest that compassion-focused therapy is more effective in enhancing psychological well-being, whereas schema therapy is more effective in strengthening sense of coherence among infertile women. Both interventions showed sustained benefits over time, highlighting the importance of incorporating structured psychological treatments into infertility care to promote adaptive functioning and resilience.

Objective: This study aimed to investigate the relationship between sexist parenting style, cognitive emotion regulation strategies, and the perpetration of domestic violence against women by married men. Methods and Materials: A correlational design was used involving 300 married men selected through convenience sampling from medical centers in Qazvin. Participants completed the Mohseni Tabrizi Domestic Violence Questionnaire and the Garnefski Cognitive Emotion Regulation Questionnaire. Descriptive statistics, Pearson correlations, and structural equation modeling using LISREL 8.80 were conducted to analyze the data. Model fit was assessed using indices including Chi-square, RMSEA, CFI, and TLI. Findings: Results indicated that sexist parenting style was positively associated with domestic violence perpetration (β = .51, p < .001). Maladaptive cognitive emotion regulation strategies were also significantly associated with increased violent behavior (β = -.39, p < .001). Model fit indices demonstrated a good fit (χ²/df = 1.41, RMSEA = .037, CFI = .97, TLI = .96). Additionally, sexist parenting and emotion regulation interacted positively in predicting violence, suggesting that both factors jointly contribute to abusive behavior. Conclusion: The findings underscore the critical role of sexist parenting and maladaptive cognitive emotion regulation strategies in perpetuating domestic violence against women. These results highlight the need for preventive interventions focusing on gender-sensitive parenting practices and training in adaptive cognitive emotion regulation strategies among men to reduce the prevalence of domestic violence.
