Standard asset pricing models based on rational expectations and homogeneity have problems explaining the complex and volatile nature of financial markets. The heterogeneity in expectations can lead to market instability and complicate dynamics of prices, which are driven by endogenous market forces. Our aim is to point out that the investors’ irrationality explains various numbers of financial anomalies, especially the phenomena that traditional financials models have never been able to explain. using a behavioral finance approach and an agent-based model we examine the dynamics of stock price fluctuations and their rates of return in an artificial market composed of fundamentalists and non-fundamentalists with loss-adverse bias. our goal is to point out a posibility that loss-adverse feature of investors explains vast number of financial stylized fact and plays an important role in price formation of financial markets.The results of intensive analysis indicate that the existence of agents having heterogeneous beliefs and preferences has provided a better understanding of price dynamics in the financial market.

Introduction and Research Goal: Given increasing dissemination rate and volume of information and, hence, rapid speeds of social and economic changes nowadays, organizations are consistently faced with complicated missions and challenges. Therefore, to reach their goals and obtain their objectives in the global competition arena, organizations have no options but respond properly to these transformations and integrate their operations by practicing a dynamic and flexible structure. Culture as one of the most significant factors affecting all organizations provides an opportunity for them to move towards achieving more flexibility and patternability. In other words, finding any solutions for consistency and uniformity within an organization (designing structure and determining methods of managing human resources) depends on culture. Method: The present study aims to examine the relationship between “culture and its dimensions” based on Edgar Shine Model and “complexity of organizational structure” at three levels, i.e. horizontal, vertical and geographical based on Richard L. Deft Model. This research has a main hypothesis and nine sub-hypotheses which are developed based on the study’s conceptual model. The data were collected through a questionnaire and analyzed at two levels, i.e. descriptively and deductively. At the description level, data (extracted from general questions) were presented in form of frequencies, percentage and charts. At the deduction level, data were analyzed using SPSS output and then Alpha Cronbach coefficient as well as Spearman coefficient were used to ratify or reject the hypotheses. Findings: The findings indicate that there is a significant relationship between “culture” and “complexity of structure”. There is a relatively insignificant relationship between “culture artifacts and culture’s main assumptions” and “complexity of structure”. There’s a relatively very significant relationship between “culture’s main assumptions” and “complexity of structure”. Manuscript profile

This paper examines the application of FACTS devices to increase the voltage stability margin in power systems. Most of the proposed methods for allocating FACTS devices consider only the normal state of the network. However, the mains voltage usually breaks down due to an unforeseen accident. Therefore, in this paper, the strategy of locating FACTS devices based on possible (unpredictable) studies is proposed. Using medal analysis, a possible index is defined that can be used to classify system buses based on their effect on improving system voltage stability, under all possible probabilities. This method has been shown to lead to integrated reactive power supply. As a result, it can be more effective in the event of a further error. The IEEE standard 14-bus network has been used to demonstrate the proposed achievement in locating parallel FACTS devices. The results show that the allocation of FACTS devices by the proposed method improves the system voltage stability under the conditions of error probability. Manuscript profile

With the rapid progress of semiconductors in the level of voltage and power of the power system as well as the progress of control systems, compensators with high flexibility and performance range have been designed and built to increase the flexibility of energy transmission systems. to be These compensators installed in power systems are called flexible ac transmission systems (FACTS). One of the most important advantages of FACTS devices in the transmission system is to increase the transient stability margin of the power system by controlling the active and reactive power of the line during the occurrence of a fault in the system. In this article, the effect of one FACTS device with parallel connection, i.e. static compensator, on transient stability is investigated. The studied system is a two-machine power system including a hydropower plant and a local power plant. The simulation results show the effect of the compensator on the damping of electric power angle fluctuations. Also, the simulation results show the lack of influence of the compensator on the transmission active power in the transmission line. The simulation results have been obtained using Simulink MATLAB software. Manuscript profile

Food labelling plays a major role in the marketing and identification of products. Given the different physical conditions of each person, the nutritional needs of individuals will also be different. In this context, manufacturers must ensure the integrity of the content and labelling of foodstuffs so that they do not confuse consumers and do not compromise their health. The purpose of this study was to determine the accuracy of the labelling information and its compliance with the criteria established by the FDA. In this descriptive-analytical study, the labelling information of 272 dairy products was recorded. Then the information was investigated with documents in the Food and Drug Administration and the general guidelines of food and beverages. The results showed that 45.2% of the samples contained descriptive statements, of which 50.18% were unauthorized. There was 50.55%, 95.6%, 68.4%, 57.5%, defect with the FDA labelling in enrichment foods, probiotic foods, health claims, and nutrition facts label, and 0.36% of the samples claims were invalid. 3.2% of the samples had nutritional claims, and 14% of the samples hadn’t traffic-light nutrition labelling. Food labels are a tool for measuring the health of products and will have a significant role in reducing NCD. This study reveals the need for more and more rigorous monitoring of food labels.

In this paper to set the parameters of FACTS devices, genetics and particle swarm optimization with fuzzy logic techniques have been used. To optimize the reactive power consumption and reduce the line congestion, two types of FACTS devices; thyristor controlled series compensator (TCSC) and static var compensator (SVC), are used. Optimal location of FACTS devices on the network, which is under heavy loads, results to reduce the power losses, reactive power control and thus reduces the operating costs of the power system. In this paper, the fuzzy membership functions are used in order to determine the weak network buses in order to install the SVC. The values of reactive power through the lines are leads to locate the line which the TCSC should be installed. The method presented in this paper have been compared with other methods (e.g. analysis of eigenvalues) for optimal location of FACTS devices. The results of the simulations presented in this paper, proves the efficiency of the proposed method. Manuscript profile

This paper introduces an innovative and creative systematic thinking method based on TRIZ thinking technique which can improve the performance of unified power flow controllers (UPFC). This new device is called distributed power flow controller (DPFC). The difference between UPFC and DPFC lies in exchanging three-phase series converter with single-phase converters that are distributed along the transmission line. This is based on one of the 40 principles of TRIZ innovative thinking technique, called segmentation. The basic changes, occurring in the DPFC, compared to UPFC are eliminating common DC-link between the series and shunt converters, and replacing three-phase series converters with single-phase series converter. These changes, lead to more economic and more reliable system. Similar to UPFC, the DPFC adjusts line impedance, transmission angle and bus voltage simultaneously. The DPFC design procedure based on differences with UPFC is described and DPFC advantages in mitigation of transmission line voltage sag and fluctuation are shown; while in some cases, simulation results of using UPFCs, DSTATCOM, TCSC and SVC indicate voltage sags. Finally, this paper introduceس one innovatively DPFC called fuzzy self-organized DPFC (FSO-DPFC) to solve the most important problem of DPFC. DPFC series converter with and without FSO controller (FSO-DPFC) are simulated. The simulation results of using FSO-DPFC, compared to traditional DPFC, shows more system ability to mitigate disturbances in the central controller signals. Manuscript profile
