Functional linguistics is regarded as one of the dominant approaches in contemporary linguistics that focuses on the functions of language. The greatest theoretician of functional linguistics Michael Halliday, in cooperation with Roqaye Hassan, have investigated the unity and coherence of text and have categorized its elements in Cohesion in English. The theory of the unity and coherence of text, which is based on the relations of sense and text, is considered as a branch of discourse analysis that investigates text. Coherence has an important and significant role in the structure of a text. The author reflects his real and surreal world in the text. Though time coherence is subverted in this reflection, he conveys meaning and creates text through language and maintaining lexical and syntactic relations.
Surrealist writers attempt to create imaginary and unreal milieus by means of free imagination and the unconscious to reach at a world beyond reality and away from preoccupations of contemporary culture. Since the surreal text is a reflection of surreal world free from limitations of language (automatism), it is assumed that such texts possess no unity and coherence and semantic relations in them is chaotic. Accordingly, this study investigates lexical cohesion of Blind Owl, in a descriptive-analytic method, based on Halliday and Hassan’s theory. The present research seeks answers to the following questions: Does the overflow of lexicons, originating from automatic writing out of the hallucinations of surrealist writer, create an incoherent text or not? Does the surrealist text take distance from language standards and their lexicons and their sentences have no unity and coherence as surrealists do in their real life? At last, it is argued whether Halliday’s linguistic theory can be useful in the analysis of surrealist texts in order to understand writer’s mentality and spirit.

According to group of researchers, the semiotic square of Greimas in some of texts, has a mechanical and solid structure and doesn’t successfully represent meanings in a discourse. They believe that the tensive square is more appropriate; because it has fluid and dynamic applications. However, fluid and dynamic deep structure of a narrative can be illustrated by using of “consecutive semiotic square”; In other words, it can be shown off the processes of the meaning production in a narrative from primary meaning to ultimate meaning. In this regard, we suggest in this study a novel model, “semiotic ladder”, to analyze narratives in the lyrical genre, to discover their inner and deep structure meanings to prove dynamic feature of meaning in the semiotic square. After analysis, it was found that the process of the semiotic ladder thanks to consecutive semiotic squares, represents the displacement and fluidity of meanings in a narrative and refuse the mechanical and solid feature of squares. Finally, the application and process of the semiotic ladder is applicable and practicable in all narratives.

Aims: Diabetic Neuropathy Pain (DNP) is a chronic condition that arises from nerve damage caused by prolonged hyperglycemia. It leads to burning, tingling, and sharp pain, primarily in the extremities. This study examines the effectiveness of Cognitive-Behavioral Therapy (CBT) in mitigating recurrent negative thoughts, reducing anxiety sensitivity, and enhancing emotional adjustment in individuals with DNP.
Method and Materials: The study employed a quasi-experimental pre-test-post-test design with a control group, involving 36 patients with DNP from Ardabil clinics located in Ardabil, Iran in 2024. Patients were purposively sampled and randomly assigned to intervention (n = 18) and control (n = 18) groups. The intervention group underwent eight 90-minute CBT sessions, while the control group received no intervention. Data were gathered using the Repetitive Negative Thinking Questionnaire, Anxiety Sensitivity Index-3, and Emotional Adjustment Measure. The collected data were analyzed using MANCOVA in SPSS-27.
Findings: The results demonstrated that CBT significantly improves emotional adjustment (F = 49.46) and reduces recurrent negative thoughts (F = 45.41), as well as physical (F = 52.27), cognitive (F = 59.61), and social dimensions of anxiety sensitivity (F = 38.34) in individuals with DNP (P < 0.001).
Conclusion: The findings highlight CBT's transformative impact on the psychological resilience of DNP patients, fostering adaptive emotional regulation and diminishing maladaptive thought patterns. By addressing the interconnected dimensions of anxiety sensitivity and emotional adjustment, CBT offers a pathway to holistic pain management, emphasizing its potential as a cornerstone in the psychological care of chronic pain conditions.

Markowitz's model which determines the weight of each stock in the portfolio is based on the optimal choice of stocks in order to maximize the expected returns. However, this theory through paying special attention to the concept of total risk reaches to an efficient frontier which undoubtedly the portion of unsystematic risk that the market doesn’t reward will not stand in the minimum level. Besides, Sharpe’s theory presents a model using some simplifying assumptions which attains a new efficient frontier in which although the concept of systematic risk governs it, its fundamental defect will absolutely be applying market portfolio in the case of investing. This article aims to combine the theories of Markowitz and Sharpe to introduce a new model. This new model is much better and more efficient in comparison to Markowitz’s efficient frontier. Moreover, it reforms the exiting defect in Sharpe’s model The superiority of proposed model over Markowitz and Sharpe's traditional models from the view point of theory is definitely proven through paying attention to unsystematic risk, eliminating some assumptions of the traditional models and finally through finding the optimal portfolio of stocks for large cement corporations in Tehran stock exchange market.

Post-traumatic stress disorder (PTSD) is a devastating mental health condition that can arise following exposure to traumatic events. This study aims to investigate the effects of cognitive behavioral therapy (CBT) on the sense of coherence, social support, and spiritual well-being among students diagnosed with PTSD. The research employed a semi-experimental, pre-, post-test design with a control group. The statistical population included students diagnosed with PTSD at the University of Tehran during the 2023-2024 academic year. A total of 36 students with PTSD were selected using purposive sampling and were divided into experimental (n=18) and control (n=18) groups. The experimental group attended eight 90-minute CBT sessions, while the control group received no intervention. Data collection involved administering the Post-Traumatic Stress Disorder Scale (Keane et al., 1998), the Sense of Coherence Scale (Antonovsky, 1993), the Social Support Questionnaire (Sherbourne & Stewart, 1991), and the Spiritual WellBeing Scale (Paloutzian & Ellison, 2012). The data were analyzed using multivariate covariance (MANCOVA) analysis in SPSS-24. The results indicated that CBT significantly increased the sense of coherence (F=40.69, p=0.001, η²=0.58), social support (F=60.50, p=0.001, η²=0.67), religious well-being (F=52.16, p=0.001, η²=0.64), and existential well-being (F=54.50, p=0.001, η²=0.65) in students with PTSD. These results support the incorporation of CBT into therapeutic programs for students with PTSD to foster resilience and holistic well-being. Future research could explore the long-term effects of CBT and its impact on other psychological and behavioral outcomes in diverse student populations.
