Effects of Using Digital Comics to Improve ESL Writing
Melor Md Yunus,Hadi Salehi,Mohamed Amin Embi
Research Journal of Applied Sciences, Engineering and Technology , 2012,
Abstract: Information Communication Technology (ICT) is used in modern education to help teachers to perform administrative tasks more efficiently and students learn more effectively. As one of the pedagogical tools that involve the application of ICT, digital comics offer many advantages, particularly in the creation of an engaging learning environment. Using digital comics as a language-learning tool clearly seems to be one of the most effective ways to teach ESL writing to students who have low proficiency in the English language. This study aims to investigate the perceptions of teacher trainees with regard to the use of digital comics in teaching writing to low-achieving ESL learners. A questionnaire survey was administered to 30 TESL teacher trainees at a state university in Malaysia. The findings showed that the teacher trainees had a positive attitude towards using ICT in teaching writing and most of them agreed that digital comics enable them to help lowachieving language learners to write in English. At the same time, however, the teacher trainees perceived the use of digital comics in the classroom as time consuming and impractical.
Visibility and Citation Impact
Nader Ale Ebrahim, Hadi Salehi Embi, Mohamed Amin Habibi Tanha,Farid Hossein Gholizadeh Motahar, Seyed Mohammad
International Education Studies , 2014, DOI: 10.5539/ies.v7n4p120
Abstract: The number of publications is the first criteria for assessing a researcher output. However, the main measurement for author productivity is the number of citations, and citations are typically related to the paper's visibility. In this paper, the relationship between article visibility and the number of citations is investigated. A case study of two researchers who are using publication marketing tools confirmed that the article visibility will greatly improve the citation impact. Some strategies to make the publications available to a larger audience have been presented at the end of this paper.

Computer Science , 2013,
Abstract: The aim of this study is to examine the effect of Information and Communication Technology (ICT) development on country's scientific ranking as measured by H-index. Moreover, this study applies ICT development sub-indices including ICT Use, ICT Access and ICT skill to find the distinct effect of these sub-indices on country's H-index. To this purpose, required data for the panel of 14 Middle East countries over the period 1995 to 2009 is collected. Findings of the current study show that ICT development increases the H-index of the sample countries. The results also indicate that ICT Use and ICT Skill sub-indices positively contribute to higher H-index but the effect of ICT access on country's H-index is not clear.
Effective Strategies for Increasing Citation Frequency
Nader Ale Ebrahim, Hadi Salehi , Mohamed Amin Embi, Farid Habibi Tanha, Hossein Gholizadeh , Seyed Mohammad Motahar, Ali Ordi
International Education Studies , 2013, DOI: 10.5539/ies.v6n11p93
Abstract: Due to the effect of citation impact on The Higher Education (THE) world university ranking system, most of the researchers are looking for some helpful techniques to increase their citation record. This paper by reviewing the relevant articles extracts 33 different ways for increasing the citations possibilities. The results show that the article visibility has tended to receive more download and citations. This is probably the first study to collect over 30 different ways to improve the citation record. Further study is needed to explore and expand these techniques in specific fields of study in order to make the results more precisely.
Ethical and Unethical Methods of Plagiarism Prevention in Academic Writing
Kaveh Bakhtiyari, Hadi Salehi, Mohamed Amin Embi, Masoud Shakiba, Azam Zavvari, Masoomeh Shahbazi-Moghadam, Nader Ale Ebrahim, Marjan Mohammadjafari
International Education Studies , 2014, DOI: 10.5539/ies.v7n7p52
Abstract: This paper discusses plagiarism origins, and the ethical solutions to prevent it. It also reviews some unethical approaches, which may be used to decrease the plagiarism rate in academic writings. We propose eight ethical techniques to avoid unconscious and accidental plagiarism in manuscripts without using online systems such as Turnitin and/or iThenticate for cross checking and plagiarism detection. The efficiency of the proposed techniques is evaluated on five different texts using students individually. After application of the techniques on the texts, they were checked by Turnitin to produce the plagiarism and similarity report. At the end, the “effective factor” of each method has been compared with each other; and the best result went to a hybrid combination of all techniques to avoid plagiarism. The hybrid of ethical methods decreased the plagiarism rate reported by Turnitin from nearly 100% to the average of 8.4% on 5 manuscripts.
Economic Growth and Internet Usage Impact on Publication Productivity among ASEAN’s and World’s Best Universities
Gholizadeh, Hossein Salehi, Hadi Embi, Mohamed Amin Danaee, Mahmoud Ordi, Ali Tanha, Farid Habibi, Nader Ale Ebrahim, Osman, Noor Azuan Abu
Modern Applied Science , 9, DOI: 10.5539/mas.v8n5p169
Abstract: Measuring the number of papers which are published each year, publication productivity is the factor which shows the reputation of universities and countries. However, the effect of growing economy and using internet on the publication productivity in Asian countries has not been discovered yet. The present research is going to figure out the publication productivity among the elite universities in Asian countries and also ten top universities around the world in the last twenty years (from 1993 to 2012). Furthermore, the current research is aimed to study the relationship among publication, gross domestic product (GDP) and internet usage. It is worth to mention that the publication of the top Ten Malaysian Universities was regarded for the similar period of time. To get the exact numbers of documents like papers, conference articles, review papers and letters which are published by the universities in the last twenty years, the writer of the same paper used the Science Direct database. Moreover, the data for GDP and the number of internet usage was collected through the World Bank database (World Data Bank).To compare all kinds of publications,one-way ANOVA was used and to investigate the impact of economic growth and internet usage on publication productivity, multiple regression analysis was applied.The results showed that the rate of publication growth was 1.9, 20.9, and 65.5 % in top universities in the world, ASEAN countries and Malaysia, respectively.The results also showed that there was a positive and significant correlation between GDP and the number of internet users with the number of publications in ASEAN and Malaysian universities. Internet usage had much more influence in comparison with the GDP in predicting the number of publications among these groups except for top ten Malaysian universities from 2003 to 2012. In summary, publication trends in top ten Malaysian and ASEAN universities are promising. However, policy makers and science managers should spend much more percentage of their GDP on Internet facilities and research studies that their outputs lead to more rapid economic growth and internet usage.
Duality and the cosmological constant
Hadi Salehi
Physics , 1997, DOI: 10.1007/BF02435959
Abstract: A dynamical theory is studied in which a scalar field $\phi$ in Einstein- Minkowski space is coupled to the four-velocity $N_{\mu}$ of a preferred inertial observer in that space. As a consistent requirement on this coupling we study a principle of duality invariance of the dynamical mass- term of $\phi$ at some universal length in the small-distance regime. In the large-distance regime duality breaking can be introduced by giving a back- ground value to $\phi$ and a back-ground direction to $N_{\mu}$. It is shown that, in an appropriate approximation, duality breaking can be related to the emergence of a characteristic phase in which the condensation of the ground state allows massive excitations with a characteristic scale of squared mass which agrees with present observational bound for the cosmological constant.
Evaporating Black Holes And An Entropic Scale-Hierarchy
Hadi Salehi
Physics , 1994,
Abstract: It is argued that a characteristic length may be associated with the entropic state of a spherically symmetric black hole in the cosmological context. This length is much smaller than the Schwarzschild-radius of a black hole and may act as a regulator of arbitrarily high frequencies apparently entering the usual derivation of Hawking's radiation.
Evaporating Black Holes and Long Range Scaling
Hadi Salehi
Physics , 2003, DOI: 10.1023/A:1025787219797
Abstract: For an effective treatment of the evaporation process of a large black hole the problem concerning the role played by the fluctuations of the (vacuum) stress tensor close to the horizon is addressed. We present arguments which establish a principal relationship between the outward fluctuations of the stress tensor close to the horizon and quantities describing the onset of the evaporation process. This suggest that the evaporation process may be described by a fluctuation-dissipation theorem relating the noise of the horizon to the black hole evaporation rate.
Translocality and a Duality Principle in Generally Covariant Quantum Field Theory
Hadi Salehi
Physics , 1999, DOI: 10.1088/0264-9381/17/4/307
Abstract: It is argued that the formal rules of correspondence between local observation procedures and observables do not exhaust the entire physical content of generally covariant quantum field theory. This result is obtained by expressing the distinguishing features of the local kinematical structure of quantum field theory in the generally covariant context in terms of a translocal structure which carries the totality of the nonlocal kinematical informations in a local region. This gives rise to a duality principle at the dynamical level which emphasizes the significance of the underlying translocal structure for modelling a minimal algebra around a given point. We discuss the emergence of classical properties from this point of view.
