Throughout history, numerous movements have been formed in various societies, and after almost all of them, thinkers have emerged who have judged the failure of that movement and theorized it. Therefore, this question arises as to why, despite the influence of movements, the subject is persuaded to its failure? To find the answer, Jacques Lacan's psycho-socio-political theories, which have a post-structural background, have been used as a method. Also, the constitutional movement, as an example, has been chosen as a case study for applying Lacan theories. The possible answer to this question, based on Lacan theories, refers to the importance of the subject's desire and fantasy in human dynamism and movement. The research findings show that the subject's belief in failure is inevitable. But this belief is not related to reality but is rooted in the perpetual and ontological gap between the subject and the other. Manuscript profile

One of the most important tools for entrepreneurial growth and development is the existence of a culture that supports entrepreneurship. In this study, the cultural barriers of entrepreneurship were identified and the entrepreneurial culture and failure culture in the entrepreneurial society were evaluated. This study was conducted on the basis of qualitative and quantitative mixed research. The statistical population included the entrepreneurs of Khorasan Razavi Technical and Vocational Training Centers, which was determined by the purposeful sampling method of snowballs due to the dispersion of the community. The results of the qualitative section showed that entrepreneurs are facing cultural barriers such as lack of culture of creativity, rejection of failure, negative attitude to risk, distrust of women's empowerment, the existence of patriarchal culture in society and organizations and parental opposition to girls' entrepreneurial activities. Also, the results of the quantitative section showed that the rate of failure in the studied community is very high and entrepreneurs agree to give the failed people a chance again. In general, the analysis of qualitative and quantitative results shows that the cultural subsystem in the entrepreneurial ecosystem is not in a good situation and the existing culture is not supportive of entrepreneurship and even prevents the emergence of entrepreneurship in many cases.

In this paper, a Wide-Area protection system to deal with rotor angle instabilities is proposed. Firstly, a system blackout model is developed and secondly the extreme contingencies that lead to large blackouts are extracted. Initiating events that ultimately lead to rotor angle instabilities are determined by artificial neural network (ANN). Coherent generators are detected by an algorithm using the data presented by phasor measurement units (PMUs). Based on identification of coherent generators, the power system is split into stable islands by disconnecting the weak interconnecting lines and load shedding. The performance of the proposed strategy is verified by simulations on the IEEE 39-bus sample power system. Manuscript profile

Resilience in power systems refers to the system's ability to withstand severe disturbances with a low probability of occurrence. Because in recent years extreme dust storms have caused severe damage to Iran's electricity industry, especially in the south and southwest, in this paper proposed a new scenario-based stochastic planning model for enhancement of power distribution systems resilience against extreme dust storms. In proposed model, in the first stage, the investment costs to improve the distribution system resilience against extreme dust storms are minimized due to the financial constraints, and in the second stage, the expected operating costs in dust storm conditions are minimized due to the operating constraints. Because network's insulation equipment are major cause of distribution system vulnerabilities in the dust storms, measures in the planning stage include replacement of porcelain insulators with silicon-rubber type, installation of automatic tie switches and installation of emergency generators. In the second stage, the measures are divided into preventive actions and corrective actions, and coordination between stages 1 and 2 is implemented in such a way that the results of each stage depend on the decision variables of the other stage. The simulation results for IEEE 33-bus test system and a 209 bus radial distribution network located in Khuzestan province, Iran, confirm the efficiency of the proposed model in different financial conditions.

Abstract Oil reservoirs are one of the important sources of energy due to which is caused by specific rock mechanical properties, the ability to maintain hydrocarbon fluids. One of the major problems that are occurred during drilling a well is instability of the wellbore. In order to prevent this difficulty its need to predict stability of the rocks by using geomechanical properties and in-situ stresses. A lack of accurate wellbore stability analysis brings many problems such as borehole washout, breakout, collapse, stuck pipes and drill bits. In the present research work the stability of an oil well located in Asmari reservoir of Ahwaz oil field was stimulated by using numerical software FLAC3D and information obtained from well log curves were evaluated and analyzed in two parts and the results were presented. Mud pressure and mud weight in outset of wellbore plastic flow and also outset of shear failure in wellbore were obtained for 7.5 meter of formation which mainly consists of limestone, marl. Well stability analysis was performed in vertical direction, minimum horizontal stress and maximum horizontal stress. Due to plastic movement and shear failure in wellbore, in first stage the mud pressure occurred is 33 and 26.4 Mpa and the second stage it reaches to 45 and 30 Mpa, respectively.It indicates that tensile failure is in direction of maximum horizontal stress and shear failure in direction of minimum horizontal stress. Subsequently, the result shows that the analysis due to the low mechanical properties of the sandstone layer indicates the maximum amount of displacement and loss. The safe mud window is small in this layer. Manuscript profile

Errors and failures are inevitable in organizations, and lately, there has been an increasing need in understanding and learning from organizational errors. The main purpose of this study is Structural analysis of the effect of learning from organizational error and failure on innovative human resource performance: The mediating role of organizational ambidexterity in the employees of the South Zagros Oil and Gas Exploitation Company. This study in terms of purpose, practical and in terms of data collection is a descriptive correlational research. The statistical population of the study includes all experts and employees of the South Zagros Oil and Gas Exploitation Company with 255 people, who are considered as a limited population and all of them have been studied by census method. Standard questionnaires with validity and reliability were used to collect research data. Finally, 248 completed questionnaires were collected and used as the basis for analysis. The results of structural equation testing using PLS 3 software showed that learning from organizational errors does not have a direct and significant effect on innovative performance, but due to the organizational ambidexterity, promotes innovative performance in the organization. In other words, organizational ambidexterity as a mediating variable plays the role of facilitator and complete mediator in the relationship between learning from organizational errors and innovative performance in the organization. The results also confirm the positive and significant effect of learning from organizational errors on organizational ambidexterity, and organizational ambidexterity on innovative performance.

Plastic gears are widely used in various industries. The advantages of these gears include their lightness, automation, low noise, easy production and low cost. However, the high wear rate, limited working temperature and low mechanical strength in polymer gears, compared to metal types, limit their application. Therefore, extensive research has been done on the performance of polymer gears in order to identify the failure mechanisms. Among the conducted researches, the researchers focus on different parts such as determining the critical torque or in other words, load bearing capacity, gear behavior at lower and higher torques than the critical torque, gear fatigue resistance, gear wear behavior on a micro and macro scale, as well as The thermal resistance of the gear is drawn. In addition, the difference in methods and the provision of new methods for checking the mentioned factors in order to check the performance of the gear can be seen in the research. In general, the type of polymer, torque and work cycle have been recognized as factors influencing the wear of polymer gears. In this research, the method and results of the research conducted on various types of gears made with commonly used polymer materials are presented. In such a way that by comparing the performance of all types of gears, it is possible to reach a general conclusion about their use. Manuscript profile

The present study aimed to know the factors, complications, and controllability of masturbation addiction in twelfth-grade students. the present research is single-case experimental research. The participants of this study are all male students. According to their own words, are addicted to masturbation and have shared it with their teacher. One person who was in the severe category was selected intentionally by considering the entry and exit criteria of the study. Finally, the person's lived experience in the stages of baseline, treatment, post-treatment, and follow-up, respectively through a semi-structured interview. It was determined in four axes that 1. The frequency of masturbation was five times a week since three months ago, and the most important reasons; Loneliness, lack of physical activity, and watching movies were mentioned 2. The consequences of starting this behavior include a drop in academic grades, avoidance of responsibility at home and isolation at school, and a drop in cheerfulness. In the last 2 axes, after two months of implementation of therapeutic techniques, the frequency of this procedure decreased to one-fifth compared to the baseline. The drop in his grades was temporary, He became more social in school and more responsible at home, and his cheerfulness increased. Controlling this problem is not only possible but also promotes health growth in social, academic, personal, and family fields. Manuscript profile

The purpose of this study was to determine the effectiveness of cognitive emotion regulation training on self-esteem and self-awareness of female students with emotional failure. The method of this research was practical and semi-experimental in which a pretest-posttest design was used with a control group. The target population of this research was 22 female students of Hekmat Razavi Institute of Higher Education who had emotional failure, selected by voluntary sampling and were randomly divided into two experimental and control groups. The experimental group received training during ten 90-minute sessions, while the control group did not undergo any intervention. Ras Love Shock Questionnaire (1999) was used to screen the subjects, and Cooper Smith's self-esteem questionnaire (1967) and Cooper Smith's self-awareness questionnaire (1997) were used in the pre-test and post-test. The findings of this research showed that cognitive emotion regulation training significantly increased self-esteem and self-awareness in the experimental group compared to the control group (p<0.05). Cognitive emotion regulation training is a suitable method to increase self-esteem and emotional self-awareness in people who have suffered emotional failure and can be used as an intervention based on empirical evidence.

The purpose of this study was to investigate the mediating role of psychological flexibility in the relationship between emotional inadequacy and tendency to risky behaviors in adolescents. The descriptive research method was of the correlation type (structural equation model). The statistical population included the teenagers of Shahrood city in 2023, out of which 300 people were selected by available sampling method. The tools used in this research included risk-taking questionnaires of Iranian teenagers, emotional deficiency and psychological flexibility questionnaire. In order to analyze the research model, the structural equation model was used the findings showed that there is a positive and significant relationship between emotional inadequacy and the tendency to risky behaviors, and psychological flexibility plays a mediating role in the relationship between emotional insufficiency and the tendency to risky behaviors. Overall, the results showed that the model had a good fit. According to the obtained results, emotional inadequacy and psychological flexibility play an important role in predicting high-risk behaviors of adolescents. Emotional inadequacy and lack of psychological flexibility can increase the incidence and persistence of high-risk behaviors, including drug use, in teenagers. Therefore, the design of interventions based on improving emotional inadequacy and increasing psychological flexibility is suggested as a basis for reducing the high-risk behaviors of this group of people.
