Rezvan Hejazi, Ameneh Bazrafshan
Open Journal of Accounting (OJAcct) , 2013, DOI: 10.4236/ojacct.2013.23011
Abstract: The purpose of this study is to investigate the perceptions of graduated accounting students in universities of Iran regarding their interest in management accounting versus other fields of accounting. Furthermore, this study determines the main factors that influence students’ interest in management accounting. In order to compile the necessary information, a questionnaire was prepared and distributed to 75 graduated accounting students. The results show that accounting students prefer financial accounting and auditing rather than management accounting. Moreover, findings indicate nine factors decline students’ interest in this branch of the accounting. Finally, using factor analysis, the results confirm the significant effect of three factors on students’ interest: education, profession, research. The paper provides additional empirical evidence to clarify which factors cause a low interest in management accounting.

Iranian Journal of Public Health , 2010,
Abstract: Background: More than 8% of Irans populations are elderly. The greatest challenge in this generation is improvement of health and quality of life. So we decided to perform an interventional study with the aim of promoting the health of the elderly.Methods: This study was a community interventional in Ekbatan Complex. Subjects were elderly. At first, need assessment was done with the participation of 200 elderly by questionnaire. Based on the need assessment, we designed the educational interventions in different fields such as nutrition, mental health, and exercise and then, we compared the results.Results: 0ne hundred elderly participated as interventional group. There were 86% women and 24% of men. Almost 59% were in the 60-69 age group. More than of the subjects were university graduates. Pre and post interventional groups were matched in age, education and gender. Regarding nutrition, second priority food in women aged 60-69 was rice and after the intervention, it was changed to vegetables (P= 0.05) but in other age groups and in the mens groups no difference were noted.Aerobic exercises in women has increased after the intervention (P= 0.01). With regards to mental health, life satisfaction among women under study has increased from 68% to 90% after the intervention (P= 0.01). Feeling happy most of the time has increased from 53% to 83% in women aged 60-69 (P= 0.01) and in men from 64% to 83% (P= 0.05) respectively.Conclusion: Policymakers should design long-term educational programs to promote the elderly lifestyles.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.4497.4500
Abstract: Vincristine is an alkaloid derived from Vinca rosea that its mechanism is to stop the mitosis cell cycle. Therefore, this drug is used in chemical treatment with high multiplication as ovarian cancer, cervical cancer and mammary cancer. This drug can have teratologic effects on fetus. But there is not enough information about pregnant women. Therefore, researchers have been tried in this study to evaluate the toxic effects of this drug in pregnant women on the newborn infants. In this study, researchers choose 40 pregnant mice and sampling units consists of the newborn infants. Firstly, the female mice have been placed near male mice and after observing the vaginal plaque, pregnant mice s were divided randomly into 2 groups as control and experimental. Mice s of the experimental group were injected by vincristine (3 mg kg-1-IP) on day 10th and 16th of gestation. The control group received distilled water. After parturition, the newborn infants were evaluated by the parameters of external morphology anomaly and the data was evaluated by t-test test and SPSS Software. The analysis of the statistics showed that the use of vincristine at during pregnancy on the newborn infants was teratologic effects. In comparing the average of the parameters in the experimental group with control group, there was significant difference (p<0.001).

Theory and Practice in Language Studies , 2012, DOI: 10.4304/tpls.2.3.619-624
Abstract: The purpose of the present study was to investigate the effect of the teacher’s error correction on the accuracy of the EFL learners’ speech. In this regard the proposed null hypothesis is: “There is no significant relationship between the teacher’s syntactic error correction and the EFL learners’ speech accuracy”. In order to test the null hypothesis, 95 students who study English as a Foreign language at Azad university, Mashhad branch participated in a TOEFL test, 40 of them were ranked as “intermediate” and were randomly assigned to the experimental and control groups. Both groups took part in an interview performed by the researcher as the pre-test. During the treatment procedure, in the experimental group, the syntactic errors of the students were corrected by the teacher as soon as they committed them in their speech. On the other hand the syntactic errors of the students’ speech in the control group were totally ignored by the teacher. After the treatment, which took 16 sessions, the students participated in another interview as the post-test. Both the pre-test and post-test interviews plus all the class discussions during the treatment were tape recorded. The interviews were scored by five raters. In order to compare the means of the post-test scores of the experimental and control groups a t-test was calculated. The observed t was 2.072 and t critical was 2.021.Since the observed t exceeded the t critical, the null hypothesis was rejected. We can conclude that “There is a significant relationship between the teacher’s syntactic error correction and the EFL learners’ speech accuracy”. The results of this study can be useful for language educators in dealing with their students’ syntactic errors in speaking.
The Workings of Simurgh Metaphor in Distributed Leadership  [PDF]
Alireza Hejazi
Open Access Library Journal (OALib Journal) , 2014, DOI: 10.4236/oalib.1100628

This article offers an organizational metaphor based on an Iranian epic Manteq-o-Teyr or The Logic of Flight. The metaphor is shaped by the story of a wise hoopoe bird whose dream was to reach a mountain called Qaf and find the great king of birds called Simurgh or Thirty Birds. The new enlightenment resonated with the Conference of the Birds, captures the idea of why and how leader and followers should connect their consciousness to each other to achieve a higher level of wisdom, mythically called Simurgh. The story communicates a metaphor that works in favor of explaining organizational components such as design, structure, environment, and boundaries in a distributed style of leadership as practiced by the hoopoe and his follower birds as a community of practice through collective wisdom.

Open Access Library PrePrints (OALib PrePrints) , 2014, DOI: 10.4236/oalib.preprints.1200054
Abstract: The purpose of the Servant Leadership Assessment Instrument (SLAI) is to assess seven key dimensions of servant leadership (love, humility, altruism, vision, trust, service, and empowerment) at organizational level. This report is a reflection of applying SLAI to understand how the employees of an Iranian economic research center in Tehran regard their leader and which values matter for them. There was no right or wrong answer to suggested statements and the participants like every other organization’s employees produced a set of responses according to their preferences. Out of 31 employees who were asked to rate their leader’s style in 42 provided statements, 20 respondents completed their rating usefully. This report reflects their views and so the survey’s findings through descriptive statistics produced by SPSS version 18.0.

Pakistan Journal of Biological Sciences , 2007,
Abstract: This study shows the ability of Artificial Neural Network (ANN) technology to be used for the prediction of the correlation between common lambsquarters (Chenopodium album L.) population, corn (Zea mays L.) population and planting pattern in different days after planting (as inputs) with common lambsquarters biomass production (as output). The number of patterns used in this study was 60 which were randomly divided into 45 and 15 data sets for training and testing the neural network, respectively. The results showed that a very good performance of the neural network is achieved. Some explanation of the predicted results is given. The multi layer perceptrons with training algorithm of backpropagation (BP) was the best one for creating nonlinear mapping between input and output parameters. The mean training of root mean square error (RMSE) was equal to 0.0156. ANN model predicted the common lambsquarters biomass with maximum RMSE, t-value, average prediction error and correlation coefficient of 0.0091, 0.985, 2.6% and 0.989, respectively. The ANN model, predicted common lambsquarters biomass within ± 5% of the measured biomass for 59.8% of the samples indicates that the ANN can potentially be used to estimate plant biomass. Adjusting ANN parameters such as learning rate, momentum, number of patterns and number of hidden nodes/layers affected the accuracy of biomass production predictions.
