Ethics is one of the topics that has been emphasized in Aristotelian wisdom. That is, wisdom has a vacuum without considering morality. Therefore, morality and wisdom are two intertwined issues, and in this research, the relationship between individual wisdom and organizational citizenship behavior of nurses of Hamedan University of Medical Sciences teaching hospitals has been tried to be done by emphasizing moral behavior, moral judgment, and moral emotion.

The current research is a quantitative research based on the applied purpose and correlation type and in terms of the data collection method. The statistical population of all nurses of Hamedan University of Medical Sciences teaching hospitals is 1527 people. The statistical sample was selected using Morgan and Karjesi's table with the relative stratified method in the number of 306 people.

The results of structural equation analysis with PLS software showed that individual wisdom had an effect on moral behavior, moral emotion, moral judgment, and organizational citizenship behavior. Also, moral emotion influenced moral judgment, organizational citizenship behavior, and ethical behavior. On the other hand, moral judgment was insignificant on moral behavior and significant on organizational citizenship behavior. Also, organizational citizenship behavior was influenced by ethical behavior.

In general, the results showed that organizational citizenship behavior is influenced by individual wisdom, as well as moral behavior, moral judgment, and moral emotion. That is, with the existence of moral components along with wisdom, we can expect citizenship behavior from employees in the organization.

Iran's government organizations, despite having excess human resources, do not have the necessary efficiency and ability to realize their inherent missions. Since many factors are involved in the lack of effective use of human resources at the disposal of the organization, one of them is authoritarian leadership style. The present study was conducted with the aim of investigating the effect of authoritarian leadership style on anti-productive behaviors with regard to the mediating role of organizational disclosure and emotional exhaustion among employees of petrochemical company in Lorestan province. The statistical population of this research included all the employees of Lorestan Province Petrochemical Company in the number of 800 people, out of which 260 people were selected by stratified random sampling method according to Morgan's table. The current research is applied in terms of purpose and descriptive-correlation in terms of research type. The main tool of data collection is a questionnaire that measures autocratic leadership style from Fareh et al. (2006) in 9 items, counterproductive behaviors from Bennett and Robinson (2000) counterproductive behavior questionnaire in 19 items, to measure fatigue. Atefi questionnaire was used by Meslesh and Jackson (1981) in 7 items and to measure organizational disclosure, the questionnaire by Alinkan et al. (2015) was used in 9 items. Relationships between latent and measured variables in the conceptual model were determined using structural equations. The results of the research show that counterproductive behaviors are influenced by authoritarian leadership style and employees who have emotional fatigue will have a positive and significant effect on counterproductive behaviors. Also, authoritarian leadership style has a positive and significant effect on organizational disclosure; But organizational disclosure has a negative and significant effect on counterproductive behaviors.

Maneuvering and controlling the attitude with the highest accuracy, speed and lowest power consumption has always been one of the challenges in the field of spacecraft control system design. The flexibility of satellites causes a change in the dynamics of the whole system. In this article, the Robust Quasi-Sliding Mode Control (RQSMC) method has been utilized to control the attitude of the flexible spacecraft in the presence of disturbances. Considering the non-linearity of the equations of the flexible spacecraft, the impossibility of modeling this system ideally and the inability of mathematical descriptions to fully explain the movement of this flight system, this article uses the RQSMC method as a suitable idea for the attitude control of the flexible spacecraft. For this purpose, the three-degree-of-freedom model of the flexible spacecraft including different disturbances in each direction under quaternion kinematics will be presented in the dynamic modeling section of this article, and then a RQSMC will be designed that also has the ability to control chattering.  The checking of functional parameters such as energy consumption index, agility index and body angular rates constraints showed that this controller has a desirable performance in accurate and fast spacecraft orientation.

Due to the special features of Instagram and Telegram and the newness of this phenomenon, many people in the society have not gained the opportunity or ability to know this space in detail and their lack of proper familiarity with this space, influence in the political, social, and economic fields. , has followed culture and security for them. Therefore, in this research, the relationship between the use of Instagram and Telegram with the security and social trust of users has been investigated. The method of this research is descriptive correlation type. The statistical population of the research included 16-19-year-old users in the 12th district of Tehran, and the statistical sample size was determined to be 380 people based on Cochran's formula. The survey data collection method and the data measurement tool was a researcher-made questionnaire. The findings of the research showed that the amount and history of using Instagram and Telegram is effective on security and social trust. Meanwhile, the correlation of social and cultural content on security and social trust is positive and significant, and the correlation between economic and security content with security and social trust is negative and significant. The relationship between the political content of Instagram and Telegram with trust and social security is not significant. Finally, virtual media has had an impact on the security and social trust of Tehran users.

Governance generally consists of two basic parts: one; Decision-making and policy-making, two; Implementation of policies and decisions. The first case is discussed in the science of public policy and the second case in the science of public administration; In other words, these two components are two sides of the same coin. Policy-making is formed by taking into account the values and interests of certain groups in a specific context of power relations, which somehow deviates from rationality. On the other hand, since public policies are mainly formulated in response to a public issue or problem and they focus on humans, they are complex and multifaceted and cannot be solved with the approaches of natural sciences. The approach based on frontics, which is derived from the word phronesis in ancient Greece by Aristotle, can be a suitable alternative for policy making and its implementation beyond the approaches of natural sciences. In the current research, taking into account the role of power in public governance and emphasizing the frontal approach, it has been tried to answer four basic questions in the field of public governance: (1) Where are we going? (2) Who benefits and who loses and with which power mechanism? (3) Is this development desirable? (4) What should we do about it? Finally, a praxis-oriented approach in governance is suggested, because it considers the difference in governance contexts and emphasizes the distinct governance of each platform from another platform; In this case, rulers should understand how to be effective in their governance field.

When the organizational ideology of an organization becomes very strong, it can affect the entire structure; and finally, there is a structure that is called the missionary (mission-oriented) structure. Therefore, the current research was carried out with the aim of identifying the components of missionary organizations.

In order to achieve this goal, In the qualitative phase, while reviewing the subject literature through Thematic Analysis approach, and semi-in-depth interviews of 15 experts who were professors and managers of Tehran University of Medical Sciences were selected by non-random sampling method; To measure the validity of the themes and validation, through data angle and to calculate the reliability of the Holsty method, which were confirmed with a coefficient of 0.98. And with the use of MAXQDA No. 12 software, effective criteria on missionary organizations were identified.

Qualitative data analysis led to the formation of fifty-one basic themes and eleven organizing themes and three overarching themes including configuration components, content components and structural components.

The results showed that the criterion of organizational ideology is one of the basic criteria and key players, which is necessary and should be taken into account in the organization of the missionary organizations.

Entrepreneurship is one of the important tools in the field of business as well as a way to face the unknown world. Government organizations, like commercial organizations, can step into new procedures and methods through entrepreneurship. The present research was conducted with the aim of presenting the development model of organizational entrepreneurship in government organizations. For this reason, it was tried to design the antecedents of organizational entrepreneurship in the form of a model. The research method is functional in terms of purpose, and structural-interpretive in terms of the method of conducting and collecting qualitative data. The statistical population of the research included experts in the field of entrepreneurship and university professors (22 people in total) who participated in the Delphi panel to extract the factors affecting organizational entrepreneurship based on the three-pronged model according to their opinion. In this way, the experts were first asked to comment on the factors affecting entrepreneurship, and classify them in three dimensions: contextual, structural and behavioral. The method of selecting experts was based on the snowball method. To collect data, firstly, through the Delphi technique, the components related to the three-pronged factors were extracted, and after reaching a general consensus, in order to relate these factors and provide a model of factors affecting organizational entrepreneurship, the interpretive structural modeling (ISM) method was used. MICMAC software for categorize and analyze the power of penetration and the degree of dependence of the factors was used. The obtained results showed that a total of 5 contextual factors, 6 behavioral factors and 11 structural factors are generally involved in the development of organizational entrepreneurship. The results also showed that in the designed model, contextual, structural and behavioral factors are the antecedents of organizational entrepreneurship. At the end of the research, practical suggestions for organizations were presented.

In addition, the mediating roles of social capital (with the impact intensity of 0.48) and knowledge exchange (with the impact intensity of 0.22) in the relationship between high performance work systems and labor productivity were confirmed. It can also be argued that social capital has a positive and significant effect on the development of the process capabilities of knowledge exchange and combination in the organizations studied.

In the current paper, a three-dimensional, steady-state model has been introduced for novel proton exchange membranes (PEM) containing dicationic ionic liquids appropriatefor elevated temperature fuel cells under an anhydrous environment. Development of such a model requires utilizing the 3D geometry and detailed mesh grid and discretization of momentum. Mass and electric charge balance equations were solved based on the information obtained from electrical and electrochemical models within various areas of the cell such as porous electrodes, gas channels, and the solid parts and current collector, especially. Additionally, a description of the electrochemical reactions on the active sites of the anode and cathode electrodes, and ions' movement through the electrolyte is considered. The equations were solved by applying a finite element method solver. Finally, the results of the model are compared with the experimental data (current density-voltage graph). This graph shows a good correlation between the model and experiments validating the present simulation. This model is also able to predict PEMFC behavior under different operational conditions

Specific properties such as pore tunability, structural variety as well as chemical, mechanical, and thermal stability, make zeolitic imidazolate frameworks (ZIFs) suitable and of high importance for practical applications. Optical and chemical sensors and supercapacitors are among these applications which necessitate the detailed study of optical and dielectric properties of ZIFs. Therefore, ZIF-8 as a zinc-based mesoporous material was studied by reflection electron energy loss spectroscopy (REELS) applying the Yubero-Tougaard algorithm which is based on dielectric response theory. The band gap energy (Eg) of ZIF-8 was determined to be 4.2 eV using an extrapolation procedure applied to an experimental REELS spectrum. Its bulk and surface energy loss functions were also determined. Inelastic mean free path (IMFP) values of electrons of different energies transported in ZIF-8 were determined and their large differences with values calculated from the Tanuma-Powell-Penn (TPP) formula were discussed. In addition, the obtained ELF was used to apply the Kramers-Kronig transformation to obtain the real part (ε1) and imaginary part (ε2) of the dielectric function (ε), refractive index (n), extinction coefficient (k), reflection coefficient (R) and absorption coefficient (µ) of ZIF-8 as important optical properties of this widely applicable material.

The results of path analysis model showed that moral leadership and personality traits have a direct and indirect negative effect on emotional fatigue. Ethical emotion and tolerance of ambiguity also play the role of mediator variable in the relationship between other variables.

By promoting concepts such as moral emotions, conscientiousness and the power of tolerating ambiguity, it is possible to create stronger moral environments that to be a prerequisite and supporter of moral behavior, and strengthen and maintain ethics in the organization and thereby reduced emotional fatigue.

The spread of internet and social networks has increased the number and speed of online rumors. In order to take more effective measures to deal with the negative effects of rumors, researchers and organizations must be aware of the main mechanism of online rumor transmission. This study is performed to investigate the employees’ information exchanges in virtual groups and their belief in rumors and their dissemination in cyberspace according to the information waterfall approach and group polarization. 

In order to collect data, survey method and data analysis of correlation type were used. The statistical population of the study included the managers and employees of Hamedan Products Distribution Unit of the Oil Company, from among whom a sample size of 236 were determined. 

The results of path analysis show that the volume of arguments has a positive and significant effect on consistency with the arguments. Consistency with arguments has a positive and significant effect on the change of belief caused by arguments. The volume of arguments and consistency both have a positive and significant effect on belief in rumors.  Change in belief resulting from arguments and belief in rumors respectively affect belief in rumors and intention to disseminate rumors positively and significantly. Consistency with arguments plays a mediating role in the relationship between the  volume of arguments and belief in rumors. Argument-induced change in belief plays a mediating role in the relationship between consistency with arguments and belief in rumors. Rumor anxiety plays a moderating role in the relationship between belief in rumors and intention to spread rumors.

The error of the inertial navigation system (INS) increases with time and leads the navigation system to instability. Hence, this paper investigates INS/GPS integration. Kalman filter is the most common way for integrating these two systems, but due to the nonlinear behavior of the INS/GPS integrated navigation system; nonlinear filters are used for data integration. Furthermore, given that GPS is capable of measuring the velocity and position of the object, these measurements are used to estimate system states (position, velocity, and orientation). In the following, we have investigated the observability of the system’s state space. Using practical data from a UAV, simulation results shows that the performance of the particle filter is better than that of the other two estimators for complex nonlinear systems with non-Gaussian noise.

Prescribing and consuming drugs more than necessary which is known as polypharmacy, is both waste of resources and harm to patients. Polypharmacy is especially important for elderly patients; therefore, the factors affecting it must be identified and analyzed properly.

In this retrospective study, first, several classifier algorithms, i.e., C4.5, SVM, KNN, MLP, and BN for polypharmacy identification were compared in terms of performance using WEKA software. In this process, 16 new features were extracted alongside the four existing features from data on 81,677 prescriptions of 19,428 outpatients aged 70 to 95 years whose prescriptions were dispensed in pharmacies contracted by the Iran Health Insurance Organization- Tehran province. The performance comparison was done using corrected t-test with resampling. In order to identify the effect of elderly patients’ characteristics on polypharmacy, two important parameters of the C4.5 were optimized by grid search using 50% of the dataset and then run on the rest of the dataset. The resulted rules were then presented in the form of a decision tree and verbal expressions.

Paired comparison of the classifiers indicated better performance of C4.5 and BN compared to the others. C4.5 had the ability to identify the factors that affect polypharmacy. In addition, parameter tuning improved the accuracy and AUC of applied algorithms. It also reduced the size of the resulted decision trees as well as the number of generated rules significantly.

The data mining approach and C4.5 can identify and explain the characteristics of the elderly effective on the polypharmacy. The higher percentage of visits to general practitioners and contacts with a limited number of pharmacies are the most important characteristics.
