The effects of uncertainty of available information on investors' behaviors on herding formation

During the past century, there were different events where herding behavior created market turbulence and many investors were hurt, significantly. In this paper, we perform a survey to investigate investors’ behavior on creating herding behavior when they face with various levels of uncertainty on available information on the market. The survey designs a questionnaire, distributes it among some investors, and analyzes the results. The findings of our survey indicate that when there is a high level of uncertainty on publicly disclosed information, most investors assign more weights on confidential information or make no decision. In the event the uncertainty is on moderate level, investors rely more on publicly announced news and follow others’ behaviors. Finally, when the level of uncertainty is low, most investors depend on public information but this uncertainty creates less herding behavior compared with the previous case. The study also indicates that those investors who are normally making their decision with high inertia are not influenced by herding behavior

PHENOMENOLOGY OF ZAR RITUAL CEREMONY WITH AN EMPHASIS ON GEOGRAPHICAL RELATIONS OF ZANGEBAR AND QESHM

Abstract. The initial exposure of human beings to nature was a terrifying encounter due to lack of sufficient cognition and human was compelled to solve lots of his mental and subjective difficulties by means of believing in existence of spirits and numerous powers. In ancient times, mental illnesses were known as the effect of supernatural powers, and sickness was known as the result of being possessed by evil spirits. The individual, who is possessed, could suffer from disease with physical and mental symptoms. In southern seashores of Iran, subduing these ghosts, which are known as "winds", would be viable by performing a ceremony called Zar. Zar have been set in the spiritual beliefs ofthis region. Studying this curative ritual, assists to comprehend the rules and beliefs of fringe inhabitants of Persian Gulf and its ritual aspect is greatly significant. Zar, which is remained from the primary tribes of east Africa, was originated from Shamanism. From psychological point of view, some of the symptoms of being haunted by winds are defined as indications of psychosis and hysterics nature; furthermore, these symptoms probably arise from an individual's mental disorders and reactions to the pressures and disputes with his social conditions. Since psychology deals with humanmind and thoughts and inner emotions, proving behavioral theories and subjective processes that are presented by psychologists and psychoanalysts, is very difficult and even doubtable. In addition, proof of issues which are derived from the humanities, is encountered with difficulties because they cannot undergo experience. In psychology, in which human mind is the main part, this case runs into more complications. Nevertheless, research methods, current tools and techniques for studying psychological subjects have rectified the mentioned defect to a large extent. Zar ritual, as a substitute for conventional medical descriptions, provides a kind of interpretation of the illness that science is notcapable of its healing.Key words: Zar, the people of the air, possession, Qeshm, Zangebar

Rhetorical Moves in Applied Linguistics Articles and their Corresponding Iranian Writer Identity

AbstractEmerging from Kaplan's (1966) pioneering work on contrastive rhetoric, rhetorical organization is today practiced with current critical views in language teaching and is regarded as a major pedagogical tool in writing various articles. The present study aimed to investigate the possible relationship between generic organizations of research articles in applied linguistics Iranian journals and negotiation of researchers’ identities. Overall, 30 published research-based articles were selected randomly from four journals. After applying Pho's (2008b) model of move analysis, the obtained results were associated with the instances of writer identity using Hyland's framework (2002). The findings demonstrated different percentages of writer identity categories across different moves of articles. Results suggested that rhetorical moves performing various functions in articles need to be carried out by specific categories of authorial identity to better satisfy the expectations of their respective applied linguistics communities

Oleuropein attenuates the progression of heart failure in rats by antioxidant and antiinflammatory effects

Abstract Much of the beneficial effects of olive products have been attributed to oleuropein. This study examined the effects of oleuropein in rats with heart failure induced by permanent ligation of left coronary arteries. Twenty-four hours after the operation, the rats were assigned to five groups including a sham assigned to receive vehicle (1 ml/day) and four coronary ligated groups assigned to receive vehicle or oleuropein at 5, 10, or 20 mg/kg/day. Five weeks later, echocardiographic and hemodynamic parameters, serum concentrations of oxidative stress, and inflammatory markers were determined. Myocardial infarction group receiving vehicle showed impaired hemodynamic and echocardiographic parameters as evidenced by decreased left ventricular systolic pressure, rate of rise and decrease of left ventricular pressure, stroke volume, ejection fraction, and cardiac output. In addition, significant reduction in superoxide dismutase and glutathione reductase was observed. Oleuropein treatment prevented the reduction of these variables. Moreover, the group had a significantly higher infarct size and serum malondialdehyde, interleukin-1β, and tumor necrosis factor-α than those of the sham group. Treatment with oleuropein prevented the increase of these variables. The results show that oleuropein attenuates the progression of heart failure, possibly by antioxidative and antiinflammatory effects

A new fuzzy optimal data replication method for data grid

These days, There are several applications where we face with large data set and it has become an important part of common resources in different scientific areas. In fact, there are many applications where there are literally huge amount of information handled either in terabyte or in petabyte. Many scientists apply huge amount of data distributed geographically around the world through advanced computing systems. The huge volume data and calculations have created new problems in accessing, processing and distribution of data. The challenges of data management infrastructure have become very difficult under a large amount of data, different geographical spaces, and complicated involved calculations. Data Grid is a remedy to all mentioned problems. In this paper, a new method of dynamic optimal data replication in data grid is introduced where it reduces the total job execution time and increases the locality in accessibilities by detecting and impacting the factors influencing the data replication. Proposed method is composed of two main phases. During the first phase is the phase of file application and replication operation. In this phase, we evaluate three factors influencing the data replication and determine whether the requested file can be replicated or it can be used from distance. In the second phase or the replacement phase, the proposed method investigates whether there is enough space in the destination to store the requested file or not. In this phase, the proposed method also chooses a replica with the lowest value for deletion by considering three replica factors to increase the performance of system. The results of simulation also indicate the improved performance of our proposed method compared with other replication methods represented in the simulator Optorsim

Potential pharmacologic treatments for COVID-19 patients: A review study

A cluster of pneumonia cases of unknown origin was detected on December 31th which led to the discovery of coronavirus disease 2019 (COVID-19). Lungs are the primary site of involvement. SARS-COV-2, which is the causative agent, enters the alveolar cells using ACE2 as a receptor. Due to exposure of first cases to Wuhan’s animal market, a zoonotic transmission was suspected. Further studies suggested human to human transmission through contact and droplets. Symptoms vary from asymptomatic to acute respiratory distress syndrome and death. Cases are diagnosed based on clinical and laboratory findings. Currently, there is no definitive treatment or vaccine and different antiviral and other treatments are being tested as possible therapeutic agents with different mechanisms, for example, Chloroquine, hydroxychloroquine, azithromycin, favipiravir, umifenovir, ribavirin, Ivermectin, etc
