Fundamental Value and Price Divergence: Evidence from Tehran's Stock Exchange
Lida Mahmoudi,Javad Moradi
Asian Economic and Financial Review , 2012,
Abstract: This paper investigates the information content of some accounting variables and degree of their association with risk and return by residual income model in Tehran stock exchange (TSE). In order to determine risk factors, we use Fama and French (1992) three-factor Model. The first contribution is that the fundamental value based on accounting figures, is highly correlated with stock prices, that is, the accounting numbers as residual income and book value and the fundamental value based on them, are important factors determining the market value of stocks. Our results indicate that beta coefficient cannot explain price differentials, and price differentials are not related to abnormal return. We further document that relative information content of price differentials and Systematic Risk are different. Finally, we find that price differentials with systematic risk do not contain incremental information content to explain returns in TSE.

Pakistan Journal of Biological Sciences , 2008,
Abstract: Vitrification is the commonly used method for long-term storage of pre-implantation mammalian embryos. It is an essential part of assisted reproductive technologies. The re-expansion rate, pregnancy and birth rate of vitrified blastocysts using CPS were compared with OPS and Conventional Straw. Female NMRI mice were injected with Gonadotrophins in order induce them for super ovulation. At that time the mice were sacrified by cervical dislocation and dissected of mouse abdomen. The uterine horns were existed blastocysts were collected in PBS and randomly allocated to four groups: vitrification in CPS, conventional straw, OPS and untreated controls. The vitrification solution was EFS40%. After storage for 1 month in liquid nitrogen, the blastocysts were thawed in 0.5 M sucrose for in vitro culture in M16 medium. After 6 h of culture, the numbers of expanded blastocysts was recorded and ready for transfer to uterus of pseudo pregnant mouse. The re-expansion rate of the CPS group (72.1%) was significantly higher (p<0.05) than OPS (52.55) and C.S. (38.6%) groups. The pregnancy (70%) and birth rate (45%) of blastocysts in CPS were similar to those of fresh blastocysts (80% and 45.5%) and the pregnancy (10%) and birth rate (5.1%) in Conventional Straws lower than OPS (20 and 7.5%), but were not significantly different. Mouse blastocysts vitrified using CPS had a better result compared with OPS and Conventional Straw. The value of CPS for vitrification of blastocysts may also merit investigation.

Allahvaysi Ozra,Solaeymani-Rad Jafar,Lida Moradi,Ghasem Saki
Journal of Biological Sciences , 2010,
Abstract: The aim of this study was to investigate ultrastructural changes of Cerebellum in 3mT electromagnetic field exposed rats. Total 30 adult female Wister rats with 3 months of age and weighing 210±10.6 g were used in this study. All female rats subdivided randomly to 2 groups: group 1, serve as untreated controls; group 2, was exposed to 3mT EMF for 4 months, 4 h day-1. After 120 days all rats were killed and their tissue samples from Cerebellum were removed and prepared for electron microscopic studies. Present finding clearly demonstrated that number of purkinje cells in the cerebellum of EMF- exposed rats were decreased significantly (p<0.01) in comparison to control group. The other changes include: condensation of nuclei, dilatation of endoplasmic reticulum, breakdown and disappearance of crista in mitochondria and vacuolization of cytoplasm in the purkinje cells of cerebellum. The mean nuclear diameter in purkinje cells were 45.35±22.85 mm and 26.79±16.36 mm in control and experimental group respectively. The statistical analysis showed that the difference between two group was significant (p = 0.03). Axial ratio of nucleus of purkinje in control and experimental groups were 1.86±0.41 and 1.55±0.14 mm, respectively. The axial ratio of nucleus in purkinje of EMF-exposed cerebellum were decreased significantly in comparison to control group (p = 0.02). These findings indicate that long-term exposure to EMF has detrimental effects on central nervous system at cellular level.
Theory of Carbon Nanotubes as Optical Nano Waveguides  [PDF]
Afshin Moradi
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2010, DOI: 10.4236/jemaa.2010.212088
Abstract: The propagation of surface plasmon waves in metallic single-walled carbon nanotubes is analyzed within the frame-work of the classical electrodynamics. The conduction electrons of the system are modelled by an in?nitesimally thin layer of free-electron gas which is described by means of the semiclassical kinetic theory of the electron dynamics. The effects of the energy band structure is taken into account and a more accurate dispersion relation for surface plasmon oscillations in the zig-zag and armchair nanotubes of metallic character is obtained.
The Role of Religious Orientation, Psychological Well-Being, and Self-Esteem in Iranian EFL Learners’ Language Achievement  [PDF]
Elham Moradi, Jahanbakhsh Langroudi
Open Journal of Modern Linguistics (OJML) , 2013, DOI: 10.4236/ojml.2013.34043
Abstract: The present study aimed at finding the relationship of religious orientation (RO), psychological well-being (PWB), and self-esteem (SE) with language achievement (LA) among Iranian EFL learners. Furthermore, it investigated the predictability of dependent variable (LA) using all independent and predictor variables (RO, PWB, and SE). 126 senior and junior students majoring in English Translation and English Literature at Shahid Bahonar University of Kerman participated in the study. To obtain the required data, three questionnaires were utilized: Allport and Ross’s (1967) Intrinsic-Extrinsic Religious Orientation Scale (IEROS) to measure extrinsic and intrinsic religious orientations, Short Measurement of Psychological Well-Being by Clarke, Marshall, Ryff, and Wheaton (2001) to measure psychological well-being, and finally, The Rosenberg Self-Esteem Scale by Rosenberg (1965) to assess self-esteem. Moreover, participants’ GPAs in major courses were used as indicators of their language achievement. For analysis of data, Pearson Product Moment Correlation and Regression analysis were used. The results revealed that there was a significant positive relationship between IRO, PWB, and SE with LA and a significant negative relationship between ERO and LA. Additionally, all the independent variables together could predict LA and accounted for 95 percent of variability of students’ GPA.

In this research, the processes have been mapped utilizing focus and established group, in parallel of software production in different maturity level of CMM mapped by COBIT framework. In order to show the capabilities of proposed framework, the hybrid evaluation model was employed in a software developing organization as a case study. According to the results of evaluation, improvements proceedings and action plans have been proposed and discussed to enhance the software production processes.

Tripartite Entanglement and Lorentz Transformation  [PDF]
Firouz Amiri, Shahpoor Moradi
Journal of Quantum Information Science (JQIS) , 2014, DOI: 10.4236/jqis.2014.43017
Abstract: Entanglement of tripartite spin states under Lorentz transformations is studied in the context of Bell’s inequality and positive partial transpose criterion. First the relativistic analogue of Bell’s inequality is discussed for three qubit states by explicit calculation of the Wigner rotation. We use the relativistic invariant spin operator which is related to the Pauli-Lubanski pseudo vector. For observers at rest the Bell’s inequality is speed-independent and maximally violated. For moving observers it’s shown that Bell’s inequality is violated and the amount of violation depends on the boost speed. We show that in ultrarelativistic limit Bell’s inequality is still maximally violated. We also obtained the critical value for satisfying Bell’s inequality. The critical value of boost speed for violation of inequality for particles moving in the center of mass frame is greater than that for particles moving with the same momentum. Second we investigate the entanglement distillability of tripartite mixed spin states under Lorentz transformations in the context of Werner states. We show that there are states that will change from distillable (entangled) into separable for a certain value of rapidity.

Mohammadreza Pourjafar, Amir Moradi
Open Journal of Ecology (OJE) , 2015, DOI: 10.4236/oje.2015.53007
Abstract: Design of greenways is one of the most important planning tools in the promotion of quality of life of the city residents. Greenways are necessary due to their major role in increase of air quality and positive changes in the climate of the urban environments for keeping the environmental quality of the cities and considerably increasing aesthetic values of these environments. Protection of natural ecological systems, provision of extensive recreational opportunities for people in urban regions and rural districts, provision of economic benefits and protection of cultural values and historical heritage are the advantages of designing and creating greenways inside cities. The present paper which was conducted with descriptive-analytical method tried to explain design dimensions of ecological greenways in three urban physical, environmental and social-economic systems by studying suitable experimental concepts and samples in the world. In this regard, this paper studied five main goals of designing greenways: promotion of local and urban accesses with greenways, aesthetic aspects of urban landscapes, improvement of performance and distribution of activities by creating greenways, increase of efficiency and environmental aspects in the city and revival of social values considering economic sustainability and in this regard design strategies and policies were presented for each one of them based on these goals.

Abstract: The purpose of this study was to examine the relationship among Iranian EFL teachers’ job satisfaction, self-efficacy, and their spiritual well-being. For this purpose, Job Satisfaction Survey (Spector, 1994), Teacher Self-Efficacy Scale (Tschannen-Moran & Woolfolk Hoy, 2001), and Spiritual Well-being Scale (Paloutzian & Ellison, 1982) were used to collect data. The statistical procedure of Pearson Product Moment Correlation was utilized using SPSS version 21. The results of the statistical test yielded a significant negative relationship between teachers’ job satisfaction and their spiritual well-being and there was no relationship between their job satisfaction and self-efficacy. Moreover, there was not any significant relationship between teachers’ sense of efficacy and spiritual well-being.
The Evolution of the Concept of International Peace and Security in light of UN Security Council Practice (End of the Cold War-Until Now)  [PDF]
Rasool Soltani, Maryam Moradi
Open Journal of Political Science (OJPS) , 2017, DOI: 10.4236/ojps.2017.71010
Abstract: With the start of globalization and the third millennium, international peace and security have gradually lost their traditional westphalian notion and have become complicated. The nature of threats against international peace and security has also spread to political, economical, social and environmental aspects as well as military ones. Therefore, it is not just governments who are responsible for establishing international peace and security; rather all the actors of the international system including individuals and major international bodies have their own share in bringing about peace and security. In this regard, UN Security Council, which is the most significant pillar of UN and guardian of international peace and security, has faced multiple challenges during its lifetime. During the Cold War and due to the competition between west and east superpowers, this council has proved principally impotent in encountering international crises. When the Cold War came to an end and the Soviet Union collapsed, there had been offered a great chance to the council to analyze international affairs with a new approach. The evolution of international peace and security notion and new interpretations of threats are the most manifested matters of the council in the post-Cold War era. This has proceeded to an extend that sometimes finding a legal status for the measures of the UN Security Council is difficult and the council has become sort of a legislator in the world. The most important issues that were addressed in the Council regarding international peace and security in post-Cold War era have been human rights violations, humanitarian law, terrorism, proliferation of mass destruction weapons and environmental problems. Expanding the Council’s authorities should be based on a clear and general interpretation of them in the framework of the principles of the UN Charter. Consequently, the Security Council is not legally capable of doing arbitrary and limitless actions.
