One of the most important components of successful entrepreneurs is decision-making in a situation that can bring many dangers and risks to them. Entrepreneurs should always make tough decisions in the conditions of uncertainty and ambiguities in the startup environment and move toward their goals based on those decisions. These decisions accompanied by risk, whether financial, social or similar, can in turn determine the success or failure of the entrepreneur. In this research, we investigate the effect of the two components of working memory and motivation on the level of risk-taking of potential entrepreneurs, and we also observe the effect of age changes on each of these variables. The sample studied in this research is 142 potential entrepreneurs who intend to start a business in the future. We used a standard questionnaire to collect information related to people's motivation, and to measure their working memory performance and risk-taking, we used computerized cognitive tests of CANTAB software. The selected people are from the startup teams of the Convergent Technologies Research Institute of Tehran University. All these people have done their test individually in an isolated environment located in the Research Institute of Convergent Technologies of Tehran University in full compliance with the test protocol. In the research findings section, the relationships between the main and secondary variables were investigated and compared with the research hypotheses. The two indices that are important for measuring the fit of the research model are Chi-square and NFI, which are suitable if they are above 5% and 0.9, respectively, which was also the case in the findings of the present study. Then the coefficients of determination and effect size were examined. In the conclusion part of the research, we examined why some hypotheses were rejected and some were confirmed, and with the help of previous literature, we examined why each one. This research showed that there is a significant relationship between motivation and risk-taking performance of potential entrepreneurs. Also, by changing the motivation level of potential entrepreneurs, their working memory performance can be affected. On the other hand, the age variable was related to all variables of working memory, motivation, and risk-taking, but its relationship with motivation was contrary to existing literature, and our findings could not be properly aligned with previous studies. The reason for this can be motivated by the breadth of literature and it is better to consider more factors in another research. With the help of the findings of this research, entrepreneurs can be helped to make their risky decisions with higher quality and thus take a smoother path to reach their entrepreneurial goals. Finally, we know that entrepreneurs are one of the important elements of economic progress and helping them succeed can help the economy and welfare of the society

This research investigates the effect of work engagement and psychological capital on workplace deviance behaviors via the mediating role of job embeddedness and the moderating role of age. The sample of research consists of 522 employees of the thirteen Districts of Mashhad’s Municipality. According to literature, a questionnaire based on 67 questions was designed. The constructs validity of the questionnaire was evaluated by using Confirmatory Factor Analysis Technique and AMOS software. The internal coherence of the tools was evaluated by employing the Cronbach's alpha coefficient. The results showed that increasing the psychological capital and job embeddedness of the employees leads to a decrease in the incidence of deviant behavior in the work environment by them. Also, with the increase of psychological capital in these employees, the level of their work engagement increases. Employees with more work engagement and psychological resources are more embedded to their organization, and they have less willingness to develop deviant behaviors in the workplace. Also, employees over the age of 40 are more committed to their organization and they have less deviance behaviors.

This paper has been done in order to: 1) Determine the level of current motives for improving staff and field police officers and leaders, 2) Consider the relation between improving motives and job performance of police officers and leaders and 3) Measure the relation between the four personal variable (education, age, rank and work experience). In order to do so, we have reviewed the field literature and researches done on this field first. Then we have modified the motive indices and estimated a measuring scale to evaluate this psychological feature and determined its validity and reliability. This scale was done on a population of 644 police leaders and officers. The data were analyzed by SPSS. The results showed that 1) The level of improving motives for police officers and leaders fluctuates, 2) there is a meaningful correlation between the level of police officers' and leaders' improving motive and their job performance and 3) There is a direct or reverse relation between police leaders' improving motives and personal characteristics.
