With the discovery of the field of nanotechnology in the last two decades, there has been a tremendous field of entrepreneurship development, including technological entrepreneurship. The existence of very large markets and the interconnection of research and scientific fields has led to a lot of entrepreneurship. Meanwhile, the study of factors affecting the discovery of technological entrepreneurship opportunities can be of great importance. Because these factors can be strengthened, they have expanded the field for entrepreneurship in the field of nanotechnology. A review of studies has shown that such a model has not been studied in internal and external research. Therefore, the present study investigates the phenomenon of discovering technological opportunities for entrepreneurship in the field of nanotechnology. For this purpose, the present paper studies the basic views on the discovery of entrepreneurial opportunities and the evolution of its theories. Then, 11 knowledge based companies in the field of nanotechnology were investigated. The analysis technique in this research is grounded in theory and the data collected from the interviews were taken in three stages and finally the final model was presented. Manuscript profile

Price limit is a kind of circuit breaker which is used in developing stock exchanges and futures markets to prevent extreme price volatility, price manipulation, and financial crashes. Generally speaking, researchers and market participant usually disagree about price limit application, its efficiency, and optimum range. Pros believe although price limit may delay price discovery, it prevents extreme price volatility and overreaction. On the other hand, cons assert that price limit causes price volatility spillover and intensify investor’s overreaction. Since there is no consensus over the price limit application and efficiency, it is recommended to study this issue using different methods. Therefore, we are trying to study price limit effects in Tehran Stock Exchange using Contrarian Investment Strategy. Our results show that price limit application in Tehran Stock Exchange delays price discovery but has nothing to do with investor’s overreaction. Consequently, it seems that regulators have prevented extreme volatility, although this constraint delays price discovery and reduces market efficiency. Manuscript profile

Using high frequency data from 33 member companies of the TEFIX30 (about 5 million data), this study examined the information content of limit order book in Tehran Stock Exchange. We try to find that does limit orders behind the best bid and offer provide useful information about stock value? And how much is their information share? We use two well-known methods based on a vector error correction model. Results show that based on Hasbrouck (Gonzalo-Granger) measure, contribution of steps 2 to 10 to price discovery is about 18% (25%) and also contribution of steps 4 to 10 that are not publicly visible is about 8% (10%).

Abstract: Given the importance of the share of oil revenues in the budget of oil-rich countries, the change of Iranian economic approach from the export of raw materials and natural resources towards the export of products and technical services in line with resistive economy polices has been taken into consideration as a significant matter. In order to achieve this change of approach, the formation of Iranian energy exchange as the fourth capital market exchange was necessary. Besides, the existence of huge reserves of petroleum and natural gas resources as well as appropriate potentials such as powerful refinery and petrochemical complexes that provide the possibility of processing, refining, and conversion of underground sources to oil and higher valued products will significantly contribute to the realization and globalization of resistive economy paradigm which relies on competition and concentration on strengths and opportunities ahead. Furthermore, the exploration of infrastructures needed for the formation of energy exchange and the feasibility study of Iranian capital market conditions compared to international energy exchanges and the establishment of Iranian Energy Exchange will pave the way for the introduction of Iranian financial oil market in the form of the first energy exchange in the Persian Gulf region and make it possible for Iran to become a huge center of energy economy in the international arena. The possibility of liberalization, removal of monopoly, transparency, and price discovery in the competitive environment of the market supply and demand will result in information transparency for cost and sales prices of domestic products and exports of refinery and petrochemical entities listed in the capital market. Furthermore, such information transparency on the performance of firms that involved in oil and gas industry will provide a secure environment for actual and legal investors to make informed investment decisions and thus to earn good returns. Finally, as the findings of the present study suggest; currently it is possible to introduce Iranian energy exchange as a reference for the discovery of prices of crude oil and those of petroleum and petrochemical products in the future.

Mystics, in their solitude and isolation, through intuition and enlightenment, which are their epistemological tools, step into spaces that reason is incapable of understanding and language is incapable of describing. These spaces are the origin of their occult and mysterious manifestations created with the help of illusions or mixtures of both. The difficulty of understanding these spaces arises from the fact that imagination and delusion are generally considered two names for a state of mind, while imagination is different from illusion because it is based on sensations. However, both are involved in building the dream world. In other words, the dream is the product of the confrontation and interaction of the two forces of fear and imagination, which itself encounters the real world. The purpose of this study is to represent the mystic state in the intuitive moments of his entry into these spaces and how he is affected by this spiritual state. The main achievement of this research is to understand that the isolation and immersion of the mystic is sometimes the basis of mystical dreams and leads the mystic to the valley of deep, different and at the same time indescribable experiences. The present study obtained its data through library method and analyzed it using descriptive method. Manuscript profile

Abu-Hasan Ali Ibn Othmaan Hojwiri (470) and Ahmad Ghazzaali (520), both arose from the same intellectual system and were both from the 'Ash'ari family. But their origins of consciousness are distinguished from each other. Thus, the territory of semantic implications and language use are different in their works – Kashf Al-Mahjub (the discovery of the Veiled) and Sawaaneh Al-Oshshaq (the Resumes of the Lovers). Ro'yat or Observation is a key and verbal term in Kashf Al-Mahjub which went under the metaphoric veil of Jamaal (beauty) by entering into Ghazzaali's spiritual discourse; and the transfer happened from reality to metaphor and from one-meaning to poly-meaning. Hojwiri discusses Observation clearly and barely, but Ghazzaali takes advantages from metaphoric use of Observation: Jamaal and visual cluster in it; that is, man, heart, sun, mirror etc. This paper deals with these two mystics' point of views about Observation and the style of which is reflected in the two texts-- KashfAlmahjuband Sawaaneh Al-Oshshaaq Manuscript profile

The Holy Quran as a divine book has always been considered by Muslim thinkers and each of them tried to present their interpretation and interpretation in a specific style to their own scientific community. Abolfotuh Razi, Rashid al-Din Meybodi and Mousavi Garmaroodi are among those who have taken great strides in the field of interpretation and translation of the Qur'an. Abolfotuh Razi is one of the most prominent preachers in the Ray region in the sixth century AH. This position has caused his interpretation to have a preacher style. One of the requirements of such a style is to pay special attention to interpretive narrations. Abu al-Futuh has been influenced by previous interpretations such as Jame 'al-Bayyan and Tebyan and has influenced later interpretations. Its linguistic style is ultimately simple and fluent, with eloquence and rhetoric specific to the fourth and fifth centuries, far removed from superficial and verbal tasks. In Kashf al-Asrar, Rashid al-Din Meybodi interprets the verses of the Qur'an three times, while at the same time he speaks in detail about recitation, revelation, news and hadiths, etc. and in the third turn he justifies and interprets the verses to the taste of Sufis and mystics. The interpretation of Kashf al-Asrar has benefited greatly from the elements and mechanisms of inducing meanings, such as imaginary, permissible, prostration, simile, and metaphor. Among the Persian translations of the Qur'an, especially in recent decades, several translations that are very fluent, accurate and beautiful have been published, one of which is the translation of Ali Mousavi Garmaroodi. In this research, it is a descriptive analysis. By comparing the interpretation of Kashf al-Asrar and the interpretation of Rawd al-Jannan by Abu al-Futuh al-Razi, both of which were written in the sixth century, with the new interpretation of Mousavi Garma Rudi, Meybodi's mystical views are influenced by other interpretations.

Symbolism is one of the important streams of poetry that contemporary poets share in this poem. The study of symbolism in semiotic poetry suggests that the poet's attitude and worldview and the main field of his poems play a central role in the analysis and interpretation of symbols. Each poet, in accordance with his interests, his thoughts and values, depicts the tone and space that the semantic load of the symbols depends on this structure. This article aims at analyzing the symbolism of Semiyah's poetry by asking the following questions: What is the emergence of symbols in semi-poetry? What are the signs of discovery of the symbol in the poetry? Mention the reasons for the poetry's poetry's attention to the symbolism, how to form a variety of symbolic images and how they are discovered in semiotic poetry. This research has been carried out in a library method, which has answered the questions by studying and analyzing the poetry of five poets of contemporary poetry (Nima, Akhavan, Forough, Shamloo, and M. Soroush). Manuscript profile

One of the issues that the mysticism of all nations revolves around is the issue of discovery and intuition. In general, mystical revelations in the Divan of Ala al-Dawla Biyabanki can be divided into two categories: formal and spiritual discovery and intuition, and each of them has its types. These formal and spiritual revelations in some respects with the theory of W.T. Stacey is applicable to discovery and intuition. In this research, the revelations of Ala al-Dawlah based on formal and spiritual conditions have been studied and then their common features such as feeling of trust, objectivity, happiness, etc. have been explained. Of course, in some of these cases, Stacey's view differs or is not compatible with some of the characteristics of Islamic revelation. In addition, the specific characteristics of formal and spiritual states have been studied, and we have finally come to the conclusion that the revelations of Ala 'al-Dawlah, in addition to conforming to some patterns of Western mysticism, are unique in their kind and in some ways superior to Western mysticism. In this research, the author also tries to answer the question of descriptive-analytical method and library method whether the poems of Ala Al-Dawlah, in spite of their abundance, expressions related to discovery and intuition, adaptability and classification in the field of literary type "Literature" Does it have "prophecies and revelations" or not?

Although there is controversy surrounding the place of grammar in foreign language teaching, it remains of great importance for learners. This explanatory mixed methods study aimed to investigate Iranian EFL learners’ perceptions of the teaching effectiveness of three computer-assisted grammar teaching methods, which mainly differ in the degree of explicitness. The participants in the quantitative phase of the study were 70 Iranian EFL learners chosen from Payam Noor University of Tabriz. Besides, 15 participants were randomly selected for the qualitative phase of the study. The participants were divided into three groups of grammar teaching, including Traditional Explicit Instruction (TEI), Implicit Input Enhancement (IIE), and Guided Discovery Method (GDM). The data was collected through the Students’ Evaluation of Educational Quality (SEEQ) questionnaire and a semi-structured interview. The results of descriptive statistics showed that the participants in all three instructional groups generally had positive perceptions of computerized grammar teaching approaches. Despite opposing views, the qualitative data analysis also confirmed the effectiveness of the methods. This study concludes with some important implications for EFL teachers, learners, and educational administrators to improve the quality of education. Manuscript profile

Methodology: This study is a survey – analytical one, it can be considered as applied research, being done in an evaluative procedures. The population studied in this research was federated search systems which were selected based on sampling process available for the two federated search system of EBSCO and Summon Discovery services. Information was collected through direct observation and organized interviews with executive managers of the two systems which is based on self-made checklist containing necessary criteria for the evaluation. Descriptive statistic was used for data analysis. Thus, according to presented criteria outlined in the checklist items, zero number was considered for having the criteria and number one for absence of the criteria. The evaluation was performed with 144 components in 9 categories of research criteria: ability to display, retrieval, user interaction, authentication interface customization design, interface design, standards and communication protocols, and vendor support criteria. Findings: Findings showed that degree of compliance of the two systems of federated search system of EBSCO and Summon Discovery Service was %93/05 and % 81 /94 respectively. However, the federated search system of EBSCO Discovery Service is most consistent with the structural criteria. Conclusion: The results of the evaluation of the two systems indicated that both the federated search systems were in on a satisfactory level. However, EBSCO Federated Search System complies with the criteria of the checklist to a greater extent. Final research findings are indicative of a proposed structural model of a national Federated search system. Manuscript profile

One of the most important topics in the field of moral epistemology is the discussion about "foundations". Although each of the factors of desire, motivation, mandatory ends, emotions, revelation and intuition are known as the basis of moral knowledge, special attention has always been focused on the basis of reason. However, if the influence of reason in discovering moral values is measured on the one hand and other bases on the other hand, how will the influence of each of the mentioned bases be and what relationships can be imagined between these knowledge bases and the basis of reason? Barbara Herman, an American philosopher, and Mulla Sadra have considerable opinions in explaining this issue, so it was important and necessary to examine their views. The research was carried out by descriptive-analytical method and using text analysis and the findings showed that assuming other bases of moral knowledge besides reason, three different relationships were extracted between them. Both thinkers claimed that desire, motivation, and obligatory ends, among other things, are necessary and dependent on reason, therefore, they have an "efficacy" relationship with reason. Considering that Mulla Sadra considered the foundations of revelation and intuition to be the support of reason, the relationship of revelation and intuition with reason was considered to be of the type of "effect" relationship, and finally, Herman claimed that emotions are neither the support of reason nor dependent on it, but a complete basis. It is independent, therefore emotions and reason were placed in an "independent" relationship. Manuscript profile
