Objective: Experiencing stress and emotional disturbances due to ending and separating from a romantic relationship is one of the most painful events for some people. We aimed to evaluate a repetitive transcranial direct current stimulation (tDCS) protocol on a girl experiencing an unmarried relationship break-up.Methods: We aimed to evaluate a tDCS protocol to the left dorsolateral prefrontal cortex (DLPFC) (10 sessions, 2 mA current intensity for 20 minutes, one session each day) on a girl experiencing an unmarried relationship break-up (In Iran, the year 2022). In order to evaluate the effect of this protocol, the assessment of love trauma (Love Trauma Inventory (LTI), depression (Beck Depression Inventory (BDI-II), anxiety Hamilton Anxiety Rating Scale (HAM-A), Cognitive Emotion Regulation Questionnaire (CERQ) and Positive and Negative Affect Schedule (PANAS) was done at different time intervals, before and after the intervention and follow-up.Results: Repetitive tDCS stimulation protocol with left anodal/right cathodal DLPFC montage may effectively reduce emotional disturbances after the experience of separating from a romantic relationship and lead to improved mood.Conclusion: In order to generalize the introduced stimulation protocol, it is necessary to investigate more in large groups of people who have experienced a romantic relationship breakup.

This study aimed to investigate the mediating role of organizational envy in the relationship between quality of work life, job burnout, and organizational productivity among employees at Zahedan University of Medical Sciences. A descriptive-correlational design was employed using structural equation modeling (SEM). A total of 165 employees were selected through convenience sampling. Data were collected using validated questionnaires: the Organizational Envy Questionnaire (Valizadeh & Azarbayejani, 2009), the Job Burnout Questionnaire (Reis & Xanthopoulou, 2015), the Quality of Work Life Questionnaire (Lopez et al., 2007), and the Organizational Productivity Questionnaire (Hersey & Goldsmith, 2002). Data were analyzed using Smart PLS–4 software, incorporating Pearson correlation, reliability and validity tests (Cronbach’s alpha, composite reliability, AVE, HTMT), and bootstrapping for mediation analysis. Organizational envy showed significant negative correlations with organizational productivity ( r = -0.43, p < 0.01) and quality of work life ( r = -0.18, p < 0.05), but was not significantly related to job burnout. Quality of work life significantly predicted reduced burnout ( β = -0.417, p < 0.001), lower envy ( β = -0.252, p < 0.05), and increased productivity (β = 0.299, p = 0.001). Organizational envy significantly reduced productivity ( β = -0.384, p < 0.001), yet it did not mediate the relationship between quality of work life and either burnout or productivity. Based on the findings, enhancing the quality of work life directly contributed to reducing job burnout and increasing organizational productivity, underscoring its strategic importance in human resource development.

Aim: The main objective of this study was to examine the differentiation, communication patterns, and conflict resolution strategies of regular couples and couples who are seeking divorce in Tehran. Method: This research utilized a descriptive correlational approach using structural equation modeling. The first group consisted of 39,282 individuals seeking divorce in Tehran who had sought assistance from family courts in 2019 and had cohabitated for a minimum of two years. The second group included regular couples in Tehran who had cohabitated for at least two years and had similar demographic characteristics as the first group. The data collection tools used in this study included the the Self-Differentiation Questionnaire (Skoron & Friedlander, 1998), the Communication Patterns Questionnaire (CPQ) (Christensen & Salari, 1984), Conflict Resolution Styles Questionnaire (Rahim, 1983). The data was analyzed using the SPSS26 software with regression method and path analysis approach. Results: Based on the findings, there is a notable distinction in all aspects of differentiation between the two groups (P=0.01). Moreover, findings revealed significant variance in mutual constructive communication, male expectation/female withdrawal communication, female expectation/male withdrawal communication, and mutual avoidance communication between the two groups (P=0.01). The average scores for these components were higher among normal couples compared to divorce applicants, thus confirming the third hypothesis of the study regarding conflict resolution differences (P=0.01). Conclusion: The results revealed variations in differentiation between couples seeking divorce and regular couples. Additionally, conflict resolution styles and communication patterns also showed differences between couples seeking divorce and regular couples.

  Objective : Aging and the onset of old age are accompanied by inevitable changes in cognitive function. Therefore, considering the aging population and the importance of cognitive functions during this sensitive period, identifying factors affecting cognitive function to enhance their cognitive abilities deserves attention. The present study aimed to investigate the relationship between optimism and mindfulness with cognitive function in the elderly. Methods : The present research employed a descriptive and correlational design. The statistical population of the study included all elderly adults residing in nursing homes in Guilan Province during the year 2020-2021. The study sample consisted of 160 elderly adults who were selected from nursing homes residents using purposive sampling. The research instruments included the Revised Life Orientation Test (LOT-R) for optimism, the Five-Factor Mindfulness Questionnaire (FFMQ) for mindfulness, and the Cognitive Performance Evaluation Questionnaire (CPEQ) for cognitive function. Data were analyzed using Pearson's correlation coefficient and multiple regression analysis (simultaneous method) at a significance level of 0.05. Results : The results showed a significant positive relationship between optimism and mindfulness with cognitive function, meaning that the more optimistic and mindful elderly adults were, the better their cognitive function. Furthermore, 34% of the variance in cognitive function was explained by optimism and mindfulness. Conclusion : Therefore, based on the findings of the present study, it can be concluded that optimism and mindfulness are important variables in predicting cognitive function (p < 0.05).

Recent advancements in neurophysiological recording technologies have led to significant complexities in managing large-scale neural data, creating potential bottlenecks in the storage, sharing, and processing within the neuroscience community. To address these challenges, we developed the Big Neuronal Data Framework (BNDF), a distributed high-performance computing (HPC) solution. BNDF leverages open-source big data frameworks, Hadoop and Spark, to offer a flexible and scalable architecture. We tested BNDF on three large-scale electrophysiological datasets from nonhuman primate brains, demonstrating improved runtimes and scalability due to its distributed design. In comparative analyses against MATLAB, a widely used platform, BNDF showcased over five times faster performance in spike sorting, a common task in neuroscience. This significant speed advantage highlights BNDF’s potential to enhance the efficiency of neural data processing and analysis, making it a valuable tool for researchers navigating the complexities of modern neural datasets. Overall, BNDF represents a promising approach to streamline the handling of extensive neural data in the field of neuroscience.
