The purpose of this paper is to analyze the relationship between default risk and momentum effect using data from companies listed on Tehran Stock Exchange.To calculate default risk,we used Black-Scholes-Merton (BSM) option pricing model. To describe momentum effect, by determining the formation period to be 6 months, and the holding period to be 3,6, or 12 months, we firstlyexamined the profitability of short term (3/6), midterm (6/6), and long term (12/6) momentum strategies and found that during 2010-2015 time period, only midterm momentum strategy is profitable.Then,we showedthere is no relationship between default risk andmomentum effect.

Market efficiency paradigm and time patterns concerned, as "calendar anomalies" is a contradictory issue for researches. TSE's market participants have a negative understanding of the 6th and 12th month of the fiscal year and this issue is rooted in the obliged credit settlement of the brokerage industry at the year-end. The purpose of this study is to investigate the TSE's total return before and after brokerage firms' year-end. Using GARCH-PQ, and data of market index in periods between 1390 and 1396, we concluded that periods of1st to 22ndof 6thand 12th months,and 22nd to the end of 6th and 12th months, have respectivelynegative and positive effectson TSE's stock index.

This study aims to investigate the correlation between the diversification and accruals quality (AQ) in Iran’s mutual funds considering two main hypotheses and four sub-hypotheses. This research investigates the effects of cases such as beta of the company, the company's return on assets, debt ratio of company, firm's size, and accrual quality on the company's cost of capital and considers the effect of mutual funds’ diversification on decreasing information risk calculated through accruals quality in Tehran Stock Exchange (TSE) and Iran Farabourse listed companies. This research investigates 42 mutual funds from 2009 to 2013. Furthermore, the financial data of companies is considered for 20 years up to 2013 in order to calculate the accruals quality. The research results indicate that the factors such as the company's beta, the company's return on assets, and the ratio of firm's debt have direct correlation with cost of capital and this indicates that the increased risk in the form of beta and debt ratio increases the investors' expected return. However, the firm's size is inversely correlated with the cost of capital indicating that the increased firm's size provides the possibility of borrowing and bargaining at lower costs for companies. Furthermore, diversification in mutual funds results in lowering information risk caused by low accrual quality. Accordingly, the result of this research can help the mutual funds’ managers and investment companies to better manage their investments

Optimal Portfolio Selection is one of the most important issues in the field of financial research. In the present study, we try to compare four various different models, which optimize three-objective portfolios using “Postmodern Portfolio Optimization Methods”, and then to solve them. These modeling approaches take into account both multidimensional nature of the portfolio selection problem and requirements imposed by investors. Concretely different models optimize the expected return, the down side risk, skewness and kurtosis given portfolio, taking into account budget, bounds and cardinality constrains. The quantification of uncertainty of the future returns on a given portfolio is approximated by means of LR-fuzzy numbers, while the moments of its returns are evaluated using possibility theory. In order to analyze the efficient portfolio, which optimize three criteria simultaneously, we build a new NSGAII algorithm, and then find the best portfolio with most Sortio ratio from the gained Pareto frontier. Thus, in this paper we choose 153 different shares from different industries and find their daily return for ten years from April of 2006 till March of 2017 and then we calculate their monthly return, downside risk, skewness, kurtosis and all of their fuzzy moments. After designing the four models and specific algorithm, we solve all of the four models for ten times and after collection of a table of the answers, compare all of them with Treyner ratio. At last, we find that using fuzzy and possibistic theory make higher return and better utilized portfolios.

The Sassanid era is one of the most brilliant in the Iranian civilization in terms of various arts development. The coastal areas of the Caspian Sea, especially Mazandaran, has long been the site of artistic manifestation with countless examples of art works kept in different museums inside and outside the country. The Sassanid art particularly depict life and glory of the kings. With a deep insight into the works, one can easily find the use of a vast array of birds, animals, plants, gods and mythological beings in symbolic ways. After reviewing and researching all the works created in the Sassanid period, a common feature attracts opinions, and that is the similarity and harmony of decorative motifs in all of these works, especially bas-reliefs, metal wares, fabrics and seals. The purpose of this research is to investigate the images of sacred animals on the Mazandaran artifacts of the Sassanid period, in response to the question of what is the relationship between the designs of sacred animals and the motifs on discovered metal works of Mazandaran. The results of this study clearly show that in most of the concepts and representations in the works produced in every part of this civilization, a common goal was pursued, and it is a struggle against evil forces. The symbolic emblems of sacred animals in Iran can be found in close connection with the beliefs and religions of that era, some of which are manifested in the form of boar and lion in the body of gods and goddesses.

The present study deals with imperative mood in Persian language based on prototype theory which is one of sub-theories of the cognitive linguistics approach. The research hypotheses are based on distinctions between the form and meaning components in the imperative mood and its distribution in the language corpus of contemporary literature. The aim of this paper is to describe and classify the criterion of the imperative mood in different language levels and beyond. According to the cognitive linguistics approach, language is part of a cognitive system and the syntactic structure of a language can't be studied separately, but all influential factors should be considered from different lingual aspects. The data analysis was carried out through descriptive and qualitative methods. It was found that the base of the verb has a high frequency in the corpus, but the form and meaning are different, with the meaning of imperative mood depending on the context. As a result, all language layers, forms and meanings in description and classification of the imperative mood should be taken into account to be analyzed cognitively.

Environmental security is one of the most important aspects of human security, which puts emphasis on sustainability of the developmental policies and that they should adjust with the environment as well as rights of future generations. Since threats to the human security mainly occur within environmental issues, this research- highlighting the relationship between human security and environmental security and pointing out the threatening causes and factors to the human security - has replied to the question that how has the environmental degradation endangered human security in Iran? This study shows adoption of policies like 1- Expansion of urbanization, 2- Population growth, 3- Consumerism and stressing the production increase, disregarding its consequences, and 4- Development of environmentally incompatible technologies have led to further utilization of fossil fuels as well as uncontrollable use of various environmental resources, increased pollution, and extensively damaged the environment which consequently endangered human security due to the severe dependence of human being to the environment.

Trying to understand the reality of the soul and its result (Self Knowledge Theology) has always attracted philosophers’ attention and has been regarded as one of the concerns of philosophical thinking. In this article, it is specified that the peripatetic philosophers, whether Greek or Islamic, have considered the soul as a chapter of naturalia and try mostly to comment on the soul’s powers and activities; they have not had any epistemological view of it. In contrast, Sheikh Eshragh closes the psychology to the theological discussions and looks at it from the epistemological point of view. His discussion is not about soul’s powers, but he provides a way to save the soul from the prison of the body and emancipate the human being from the darkness of material world. In the illuminationist philosophy, the theory of intuition was proposed for the first time (The substantial form), so it has discussed the nature of the soul from this viewpoint. Suhrawardi’s psychology isn’t a consequence of theoretical discussion, but it results from introspection and self-awareness that is possible only through the asceticism and controlling the dragon of carnal soul. It is soul which shows not only the Light of Lights, but it becomes divine and finally through this path he founds his luminous system. The system of being is realized through the epistemology of soul.
