Bibliometric Analysis of Gold Open Access in India     

Mohammad Nazim 《International Information and Library Review》2018,50(1):13-23

This study analyzes the current state of gold Open Access (OA) in India based on papers published in the Web of Science indexed journals. It specifically focuses on research output published in OA journals and examines the difference between gold OA and general research output for papers authored by Indian researchers. In order to analyze the Indian contribution of gold OA literature and compares with other countries, Web of Science?-Core Collection was used. There is an increasing trend of contributing research papers in OA journals by Indian researchers. Among the top 20 publishing countries India ranks 10th place in terms of the general research output, but secures 8th place in terms of gold OA papers. However, India's position in terms of share of gold OA publications is relatively higher than other leading countries of the world. Researchers in India mostly prefer to contribute their gold OA papers in Indian journals rather foreign journals and the proportion of gold OA research output in Clinical, Preclinical, Health, Life Sciences and Physicals Sciences is much higher than other disciplines such as Arts &; Humanities and Social Sciences. Since most of the research output in India is published in local journals, the study suggests further analyses of publications which are not published in Web of Science indexed journals.  相似文献   

Cultural acceptability and personal willingness of Iranian students toward cadaveric donation          下载免费PDF全文

Jamal Abbasi Asl  Hossein Nikzad  Aliakbar Taherian  Mohammad Ali Atlasi  Homayoun Naderian  Gholamabbas Mousavi  Milad Motalebi Kashani  Abdollah Omidi 《Anatomical sciences education》2017,10(2):120-126

Cadaver dissection stands as a crucial component in medical curricula around the world, although computer‐based multimedia programs have been introduced in order to replace the need for cadaver donations. Due to a decrease in the number of unclaimed bodies and rather few donations, there is an insufficient number of cadavers for anatomical studies in Iran. This study was carried out to evaluate medical students' awareness and willingness regarding body donation in Kashan University of Medical Sciences, Iran. In this study, a questionnaire was designed to focus on the cultural acceptability and personal willingness to donate one's body after death. Students from the university's anatomy classes (n = 331) participated in this study. Seventy‐seven percent of the students expressed their agreement toward the idea of utilizing body donation services, though only 25.4% of participants were willing to donate their own bodies. None of the demographic factors were associated with cultural acceptability or personal willingness towards body donation. These findings indicated that besides “payment”, other factors were associated with students' willingness to become donors. All factors of awareness except “previous awareness of organization” were associated with cultural acceptability. In this study, students suggested that encouraging people to register for body donation using mass media (25.6%) and teaching students to respect cadavers in the dissection environment (24.8%) were the best solutions for addressing the lack of cadavers. These findings indicated that a lack of awareness about body donation might be the main factor responsible for unwillingness towards body donation; therefore, improving the public's awareness and addressing the willingness of students regarding body donation may help overcome the current lack of donated cadavers.

The resilience of the MBA in emerging economies: student motivations for wanting an MBA in China and the United Arab Emirates     

Stephen Wilkins  Lan He  Li Zhu  Mohammad Elmoshnib 《Journal of Higher Education Policy & Management》2018,40(3):256-271

In recent years, domestic demand for MBAs has fallen in most major Western markets but has increased or remained stable in emerging economies such as China and the United Arab Emirates (UAE), which are the two countries globally that host the largest numbers of international branch campuses. Thus, this research aimed to discover why students in China and the UAE still want an MBA. A survey questionnaire was completed by a total of 354 MBA students, at two universities in China and two universities in the UAE. Some of the results were surprising and unexpected. For example, recognition, prestige and networking – all key features in Chinese and Emirati societies – were found not to be key motivators for wanting an MBA. Instead, the desire to acquire knowledge and skills was the strongest motivator among respondents, accounting for 32.4 per cent of variance. This was followed by reasons associated with intrinsic benefits. The findings have implications for institutional strategy, curriculum design, program delivery and the marketing of programs.  相似文献

Shirin Barzanjeh Atri  Mohammad Hassan Sahebi Hagh  Mohammad Asghari Jafarabadi  Aram Feizi 《Educational gerontology》2013,39(9):562-571

ABSTRACT

Objective: This study was designed with the purpose of determining the relationship between social capital and lifestyle and their sub-variables among older adults.

Methods: This is a cross-sectional study using interviews that was conducted in 2017. This study was performed with randomly selected older people over 60 years of age in an urban area of Iran. Data were collected using a questionnaire in 3-month duration. The relationship between the study variables (lifestyle and social capital) was assessed through correlation analysis (in the case of non control of the underlying variables) and general linear modeling (in the case of control of the underlying variables). Data were analyzed using SPSS v.24 software at a 0.05 significant level.

Results: A total of 512 questionnaires were filed out. According to the Pearson correlation test, all social capital variables were associated with lifestyle components. However, in the general linear model test, feeling of trust and safety (p < 0.001), value of life (p = 0.030), and social participation (p = 0.004) had a significant relationship with the lifestyle.

Conclusions: The results indicated that social capital and lifestyle in the older adults were interconnected. Therefore, there is a need to improve social capital factors, especially social participation, feeling of trust and safety, and value of life, which is in-line with the strategies of achieving healthy older population. The results can be used to learn how to increase lifestyle in older adults.  相似文献   

Dry Skulls and Cone Beam Computed Tomography (CBCT) for Teaching Orofacial Bone Anatomy to Undergraduate Dental Students     

Fabio Savoldi  Andy W. K. Yeung  Ray Tanaka  Lisa S. Mohammad Zadeh  Carla Montalvao  Michael M. Bornstein  James K. H. Tsoi 《Anatomical sciences education》2021,14(1):62-70

Learning bone anatomy of the skull is a complex topic involving three-dimensional information. The impact of the use of human dry skulls and cone beam computed tomography (CBCT) imaging was investigated in the teaching of undergraduate dental students. Sixty-four first-year students in the University of Hong Kong were randomly divided into eight groups. Four teaching methods were tested: (1) CBCT followed by standard lecture, (2) CBCT followed by lecture with skulls, (3) standard lecture followed by CBCT, and (4) lecture with skulls followed by CBCT. After each, students were given a multiple-choice questionnaire to assess their objective learning outcome (20 questions) and a questionnaire for their subjective satisfaction (10 statements). Surveys were assessed with Cronbach's alpha, Kendall's tau-b, and principal components analysis. Data were analyzed with Student's t-test and a one-way ANOVA (significance α = 0.05). Standard lecture followed by CBCT showed the highest learning outcome score (81.6% ± 14.1%), but no significant difference was present among four teaching methods. Cone beam computed tomography followed by lecture with skulls scored the highest overall subjective satisfaction (4.9 ± 0.8 out of 6), but no significant difference was present among teaching methods. Nevertheless, students' perception of learning was positively influenced by the use of skulls (P = 0.018). The timing of administration of the CBCT did not affect students' subjective satisfaction or objective learning outcome. Students perceived to learn more by using skulls, but their objective learning outcomes were not significantly affected. A discrepancy seems to exist between students' perception of learning and their effective performance.  相似文献   

An exact analytical solution for convective heat transfer in rectangular ducts     

Mohammad Mohsen Shahmardan  Mahmood Norouzi  Mohammad Hassan Kayhani  Amin Amiri Delouei 《浙江大学学报(A卷英文版)》2012,13(10):768-781

An exact analytical solution is obtained for convective heat transfer in straight ducts with rectangular cross-sections for the first time. This solution is valid for both H1 and H2 boundary conditions, which are related to fully developed convective heat transfer under constant heat flux at the duct walls. The separation of variables method and various other mathematical techniques are used to find the closed form of the temperature distribution. The local and mean Nusselt numbers are also obtained as functions of the aspect ratio. A new physical constraint is presented to solve the Neumann problem in non-dimensional analysis for the H2 boundary conditions. This is one of the major innovations of the current study. The analytical results indicate a singularity occurs at a critical aspect ratio of 2.4912 when calculating the local and mean Nusselt numbers.  相似文献   

Numerical study of the melting of nano-enhanced phase change material in a square cavity     

Seyed Sahand SEBTI  Mohammad MASTIANI  Hooshyar MIRZAEI  Abdolrahman DADVAND  Sina KASHANI  Seyed Amir HOSSEINI 《浙江大学学报(A卷英文版)》2013,14(5):307-316

A comprehensive numerical study was conducted to investigate heat transfer enhancement during the melting process in a 2D square cavity through dispersion of nanoparticles. A paraffin-based nanofluid containing various volume fractions of Cu was applied. The governing equations were solved on a non-uniform mesh using a pressure-based finite volume method with an enthalpy porosity technique to trace the solid-liquid interface. The effects of nanoparticle dispersion in a pure fluid and of some significant parameters, namely nanoparticle volume fraction, cavity size and hot wall temperature, on the fluid flow, heat transfer features and melting time were studied. The results are presented in terms of temperature and velocity profiles, streamlines, isotherms, moving interface position, solid fraction and dimensionless heat flux. The suspended nanoparticles caused an increase in thermal conductivity of nano-enhanced phase change material (NEPCM) compared to conventional PCM, resulting in heat transfer enhancement and a higher melting rate. In addition, the nanofluid heat transfer rate increased and the melting time decreased as the volume fraction of nanoparticles increased. The higher temperature difference between the melting temperature and the hot wall temperature expedited the melting process of NEPCM.  相似文献   

Non-occupational lead exposure and hypertension in Pakistani adults

INTRODUCTION Blood-Pb levels are taken as representative of dose/exposure, as all clinical symptoms resulting from the toxic effects of Pb are manifested mainly in blood. Lead exposure of children correlates with de- creased IQ, symptoms of hyper kinesis or minima brain dysfunction, poor learning, or defects in specific neuromotor tasks (Landgrin et al., 1980). Large number of observations over the years has associated lead exposure with human diseases (McMichael and Johnson, 1982). Ca…  相似文献   

Implicit higher-order moment matching technique for model reduction of quadratic-bilinear systems     

Mian Mohammad Arsalan Asif  Mian Ilyas Ahmad  Peter Benner  Lihong Feng  Tatjana Stykel 《Journal of The Franklin Institute》2021,358(3):2015-2038

We propose a projection based multi-moment matching method for model order reduction of quadratic-bilinear systems. The goal is to construct a reduced system that ensures higher-order moment matching for the multivariate transfer functions appearing in the input-output representation of the non-linear system. An existing technique achieves this for the first two multivariate transfer functions, in what is called the symmetric form of the multivariate transfer functions. We extend this framework to an equivalent and simplified form, the regular form, which allows us to show moment matching for the first three multivariate transfer functions. Numerical results for three benchmark examples of quadratic-bilinear systems show that the proposed framework exhibits better performance with reduced computational cost in comparison to existing techniques.  相似文献   

The ethical attitudes of information technology professionals: a comparative study between the USA and the Middle East     

Luay Tahat  Mohammad I. Elian  Nabeel N. Sawalha  Fuad N. Al-Shaikh 《Ethics and Information Technology》2014,16(3):241-249

This paper aims at investigating comparatively the ethical orientation of information technology (IT) professionals in the Middle East and the United States. It tests for attitudes toward and awareness of ethically-related issues, namely intellectual property, privacy and other general ethical IT aspects. In addition, through a comparison between the two regions, this paper intends to examine whether differences in IT professional demographics and characteristics, including gender and academic level, have any impact on attitudes to business ethics. A t test is used to establish significant differences between the targeted samples, while an ANOVA F-test is conducted to determine significant differences among the sample countries on a group basis. The results show a general awareness of ethical issues concerning information technology, and no significant differences are found between the two samples. However, different ethical attitudes are reported among respondents in terms of their reactions to the targeted IT ethical aspects. On an individual sample basis, the results about gender support the claim that male and female respondents are different, while mixed results are revealed for the influence of academic level on attitudes towards IT ethics. For intellectual property, the results are significant regarding ethical attitude differences between Middle-Eastern professionals and their counterparts in the US, while no significance differences are reported in terms of privacy.  相似文献
