Present-day development of information technologies is making deeper and deeper incursions into all spheres of human activity, both social and economic. It is only natural that they greatly influence the educational industry, changing the approaches, methods and forms of education. Currently e-learning and distance technologies are being actively introduced into both academic and corporate education, as complementary to traditional forms. The efforts of teachers are aimed at finding effective models of blended learning. All this determines the relevance of the present study. The abstracted article is aimed at developing frameworks of a distance learning model based on the use of modern learning management systems. To obtain thorough and reliable results the authors make use of two research approaches: acmeological and competence-based. They review the features, the scope and use of the existing LMS platforms and work out tools for the development of e-learning system. In addition, they assess the compliance of e-learning tools with the preferences of X, Y and Z generation users. The outcome of the research is the development of a universal competency that can be applied to the study of modern methods and approaches with reference to both academic teaching and learning, and to corporate training. It is quite apparent that pros and cons of the learning management system and its possibilities should be carefully studied and thoughtfully used. The effective e-learning requires constant monitoring of equipment, proper work of host servers and considering user-friendliness of the platforms. This is related to the fact that public educational organizations, including schools, colleges and universities, especially in low developed countries, prefer traditional teaching methods and are slowly moving to innovative models. The research findings can be viewed as a step forward in creating user-friendly and flexible e-learning platforms, suitable for separate users, institutions and businesses. They can be applied for further assessment of existing learning models, especially for the younger generation, and for research and development of new strategies and methods of using learning management systems and platforms.
PurposeNowadays, cloud platforms are used in many fields, including e-commerce, web applications, data storage, healthcare, gaming, mobile social networks, etc. However, security and privacy are still two significant concerns in this area. The target of this paper is to present a system for trust management in industrial cloud computing using the multi-criteria decision making (MCDM) approach. MCDM techniques have been developed to accommodate a wide range of applications. As a result, hundreds of approaches have been generated with even minor variations on current approaches spawning new study fields.Design/methodology/approachCloud computing provides a fully scalable, accessible and flexible computing platform for various applications. Due to the multiple applications that cloud computing has found in numerous life features, users and providers have considered providing security in cloud communications. Due to its distributive nature, dynamic space and lack of transparency in performing cloud computing, it faces many challenges in providing security. For security improvement, trust management can play a very influential role. This paper proposes a generic analytical methodology that uses a series of assessment criteria to evaluate current trust management testing prototypes in industrial cloud computing and related fields. The authors utilize a MCDM approach in the present article. Due to the multi-dimensionality of the sustainability objective and the complexities of socio-economic and biophysical processes, MCDM approaches have become progressively common in decision-making for sustainable energy.FindingsThe results of comparing and evaluating the performance of this model show its ability to manage trust and the ability to adapt to changes in the behavior of service providers quickly. Using a simulation, all results are confirmed. The results of simulations and evaluation of the present paper indicate that the proposed model provides a more accurate evaluation of the credibility of cloud service providers than other models.Practical implicationsThe number of cloud services and customers is vast and extremely competitive in cloud environments, where novel cloud services and customers can join at any time, while others can withdraw whenever they want. Because of cloud services' highly dynamic and dispersed design, trust management mechanisms must be highly flexible to obtain feedback and update trust outcomes as quickly as possible. The model presented in this article tries to improve users' trust in the cloud industry.Originality/valueUsing a method (MCDM) to find the best trust management solution based on user experience in industrial cloud computing is the novelty of this paper.

This research compared the impacts of Persian and English cultural background knowledge on Iranian EFL learners’ listening skill. To that purpose, the Oxford Quick Placement Test (OQPT) was given to 86 Iranian EFL students; 50 of them were chosen as research participants. The respondents were then divided into two equal experimental groups (EGs) at random (Persian culture and English culture). A listening pretest was then given to both groups. The individuals in both EGs were then given the treatment. The researchers taught one EG by using the English cultural materials, while they taught the other group through the Persian cultural materials. The data were analyzed by utilizing paired samples and independent samples t-tests after the listening posttest was administered. The results showed that both EGs performed better on their posttests than on their pretests, and that there were no significant differences between the impacts of English cultural background knowledge and Persian cultural background knowledge on the listening skills of EFL students. The implications of this research can persuade EFL English teachers to incorporate more cultural-based materials into their teaching process.
