Efficiency of antibiotics and gamma irradiation in eliminating Streptomyces strains isolated from paintings of ancient Egyptian tombs     

Mahmoud E.F. Abdel-Haliem  Mona F. Ali  Mohamed F. Ghaly  Akmal A. Sakr 《Journal of Cultural Heritage》2013,14(1):45-50

Forty-six Streptomyces strains were isolated from paintings and stone surfaces from Tell Basta and Tanis tombs (80 km south-east Cairo, Egypt). Eight of these strains were selected to determine their sensitivity against 13 antibiotics. In general, high levels of resistance could be observed. Gentamycin, spiramycin and doxycycline were the most effective antibiotics against the majority of strains under study. Due to the observed antibiotic resistances, gamma irradiation was studied as a possible alternative to inhibit microbial growth. Isolated bacteria were exposed to different doses of gamma irradiation (5, 10, 15, 20 and 25 kGy). The growth of all Streptomyces isolates except S. canarius was completely inhibited at 25 kGy. The applied doses of gamma irradiation did not cause any observable alterations or colour changes to pigments and binding media (arabic gum, animal glue and egg-yolk) used in the paintings.  相似文献   

Robust packet-based nonlinear fuzzy networked control systems     

Magdi S. Mahmoud  Yuanqing Xia  Sixing Zhang 《Journal of The Franklin Institute》2019,356(3):1502-1521

A class of networked nonlinear control systems with norm-bounded uncertainties is presented in this paper. The class is represented by Takagi–Sugeno (T-S) fuzzy models with packet processing. The network loop delay is considered either as known delay or random delay. For the former case, we develop conditions that guarantee the robust asymptotic stability and state-feedback stabilization with strict dissipativity and cast the results in linear matrix inequality (LMI) framework. Next employing a probabilistic-based delay partitioning method to deal with random delay, we establish novel LMI criteria for strict dissipative stability analysis and feedback synthesis. The efficacy of the ensuing techniques is demonstrated by numerical solution of typical examples and Mont Carlo simulation.  相似文献   

Culture and country choice of international students: evidence from Ghana

ABSTRACT

This study seeks to examine the influence of the cultural elements on international students’ country choice. It also examines whether individual values moderate the influence of cultural elements on the country choice of international students. Drawing upon a sample size of 223, the data was analysed using structural equation modelling technique. Among the five cultural elements, education, language and social institutions were found to have a positive significant influence on the international student’s country choice. When moderated by individual values education was found to be the only key significant value to international students when selecting a country to further their education. The cultural elements should be given much attention by marketers, government and managers of academic institutions. An improvement in the standards of education in developing countries would attract more students from developed countries.  相似文献   

Towards the successful integration of e-learning systems in higher education in Iraq: A student perspective

This study aims to analyse the factors that can explain the adoption and effective use of a new e-learning system in Iraq. To achieve this, it uses a selection of factors that are present in the technology acceptance model (TAM) and the unified theory of acceptance and use of technology (UTAUT) model, and it includes three additional factors. The study hypothesises new relationships between the selected factors. Questionnaires were distributed to 300 university students in Iraq. Partial least squares-structural equation modelling (PLS-SEM) was used to analyse the data received. The findings suggest that perceived usefulness (PU), perceived ease of use (PEOU), subjective norms (SNs), information quality (IQ), system quality (SQ), technical support (TS) and self-efficacy (SE) have significant effects on behavioural intention (BI). In turn, BI and TS have significant direct effects on the actual use (AU) of e-learning systems. The factors age, gender and experience significantly moderated some of the relationships in the model. The research has several implications for policy makers, universities and the management of e-learning systems.  相似文献

Early career researchers: Scholarly behaviour and the prospect of change          下载免费PDF全文

David Nicholas  Anthony Watkinson  Cherifa Boukacem‐Zeghmouri  Blanca Rodríguez‐Bravo  Jie Xu  Abdullah Abrizah  Marzena Świgoń  Eti Herman 《Learned Publishing》2017,30(2):157-166

Early career researchers (ECRs) are of great interest because they are the new (and biggest) wave of researchers. They merit long and detailed investigation, and towards this end, this overarching paper provides a summary of the first‐year findings of a 3‐year, longitudinal study of 116 science and social science ECRs who have published nearly 1,200 papers and come from 7 countries and 81 universities. ECRs were interviewed in their own languages face‐to‐face, by Skype, or telephone. The study focused on the attitudes and behaviours of ECRs with respect to scholarly communications and the extent to which they are adopting new and disruptive technologies, such as social media, online communities, and Open Science. The main findings include: publishing in high‐impact factor journals is the only reputational game in town; online scholarly communities, and ResearchGate in particular, are gaining ground; social media are beginning to have an impact, especially in the dissemination arena; outreach activities have become more important; libraries are becoming increasingly invisible to ECRs; Open Science is not gaining traction; and more transformational ideas are being expressed, especially in the US and UK.  相似文献   

Computer self-efficacy of university faculty in Lebanon     

Hanadi Kassem Saleh 《Educational technology research and development : ETR & D》2008,56(2):229-240

Faculty use of technology is a critical issue in higher education; administrators and students are expecting faculty instruction to incorporate technology in classroom and distance education. Competition is demanding technologically proficient graduates for schools and colleges. Research indicates that computer self-efficacy (CSE) may be one determinant of who uses technology and who does not. A survey of education faculty at the Lebanese University in Beirut, Lebanon, conducted in 2006, revealed varying degrees of CSE; of 127 respondents, 14 had low levels of CSE; 68 were at a moderate level, and 45 self-evaluated themselves to have high CSE. Although other barriers may deter the implementation of technology in teaching, strategies and techniques for increasing CSE should be developed. For those with low CSE, special attention must be given to enhancing their levels of CSE.

DESCRIPTIVE MODELS OF STUDENT DECISION BEHAVIOUR IN EVALUATION OF HIGHER EDUCATION     

Mohamed M. Mahmoud 《Assessment & Evaluation in Higher Education》1991,16(2):133-148

Sound assessment and evaluation of higher education necessitates deep understanding of the detailed processes underlying student overall evaluation of course and Instructor. The present study employs both correlational analysis and step‐wise multiple regression in an effort to help us understand student decision behaviour and to build mathematical models representing the dynamics of student evaluative Judgement of course and instructor. The resulting models were very strong and were ctually used to improve the performance of the academic programmes in the Institute of Banking Studies In Kuwait.  相似文献   

The cultural milieu of counseling     

Mahmoud A. Saleh 《International journal for the advancement of counseling》1989,12(1):3-11

This article explores the mono-cultural milieu of counseling. There are four primary contributors to the cultural domination of counseling by the Western culture. They are as follows: (1) the deep historical and philosophical roots of counseling in Western culture; (2) the dominant theories, practices and approaches of counseling make the assumption that counseling will take place within a Western culture; (3) the bulk of research and literature pertaining to counseling concentrates on counseling within the West; (4) the emulation by non-Western nations of Western models of counseling. The concept of cultural dissonance is given to help in the understanding of the relation of culture to a counseling relationship at a given time between counselor and client.  相似文献
