This quantitative, qualitative study investigates the usage of mobile phone applications in teaching and learning processes. The study aims to identify the benefits, difficulties, and resolutions of using mobile phone applications. The study was conducted in the English Department at Hebron University at the second semester of the academic years 2015/2016. The study focuses on the Business Engl...

This paper focuses on the ergonomics evaluation of Medical Tablet Personal Computers (MTPCs). The research questions for the study were “What are the key ergonomics issues in the safe and effective use of a Medical Tablet PC” and “How can we evaluate new Medical Tablet PC concepts in the early stages of the design process”. The aims of the study were to develop an ergonomics checklist for the e...

the concepts of free modules, projective modules, injective modules and the likeform an important area in module theory. the notion of free fuzzy modules was introducedby muganda as an extension of free modules in the fuzzy context. zahedi and ameriintroduced the concept of projective and injective l-modules. in this paper we give analternate definition for projective l-modules. we prove that e...

Usage control models provide an integration of access control, digital rights, and trust management. To achieve this integration, usage control models support additional concepts such as attribute mutability and continuity of decision. However, these concepts may introduce an additional level of complexity to the underlying model, rendering its definition a cumbersome and prone to errors proces...

A combination of information systems and socio-psychological concepts holds the potential to exert a positive influence on the energy consumption of individuals. In a field study among 9,929 users, we investigate whether descriptive and injunctive normative feedback lead to significant effects on energy demand if delivered by a website have the same effects as when delivered via personal intera...

In this conceptual article we investigate the cultural dimension of IT-usage through the concept of ITacculturation. This concept has been emerging in the research literature about IT-usage. Extending work from the acculturation field of research, we do not conceptualize IT-acculturation as a simple one-way linear process but rather as a recursive, multi-level process and also as a state at a g...

Capacity planning is a critical task in network management. It identifies how much capacity is needed to match future traffic demand. It directly affects customer satisfaction and revenues. In this work we present a network usage analysis tool called Dynamic Netvalue Analyzer (DNA), which helps alleviate a big problem that network engineers and marketing executives face– making optimal resource...

Although widely used in software engineering, metaprogramming is often misunderstood. The researchers often disagree what concepts characterize metaprogramming. The concepts of metaprogramming are often used without acknowledging the usage of metaprogramming itself. We overview the examples and definitions of metaprogramming in computer science, identify, describe and discuss the fundamental co...

Language is a cognitive map of concepts. A cognitive dictionary maps our shared reality as represented by linguistic competence of all speakers. COG offers a systematic description of concepts defined by their language usage. The ‘usage’ is formalized and the paper describes format and rules employed in constructing this new type of lexicographic COG databases. A concept “entry” is a descriptio...
