BACKGROUND The aim of the present study was to evaluate the cyclic fatigue resistance of Mtwo NiTi rotary instruments after clinical use by 1 experienced and 1 novice operator. MATERIAL/METHODS Cyclic fatigue testing of instruments was performed on tapered artificial canals with a 5 mm radius of curvature and 60° angle of curvature. Twenty Mtwo instruments for each size were selected and divid...

This study examined the classroom practice and beliefs of two novice teachers, Anne and Rachel, during their first year of teaching and during the first year of their involvement in Project PRIME, a district-wide professional development project. The research also analysed the challenges faced by the novice teachers and the professional developer who worked with them. Using accounts of practice...

In this paper we present a short survey of fuzzy and Semantic approaches to Knowledge Extraction. The goal of such approaches is to define flexible Knowledge Extraction Systems able to deal with the inherent vagueness and uncertainty of the Extraction process. It has long been recognised that interactivity improves the effectiveness of Knowledge Extraction systems. Novice users’ queries are the...

Conveying a positive User eXperience (UX) is essential for the success of any application, as it affects use a product. Nevertheless, novice software engineers may have difficulties in finding an appropriate solution for UX problems due to their lack of knowledge in interface design. User interface design patterns are well-working solutions to user problems that occur repeatedly which can help ...

Despite rapid growth in the number of web sites, there is still a significant number of ergonomic problems which hinder web users. Many studies focus on analysing cognitive processes and difficulties experienced by web users, but very few are interested in web designers’ difficulties or in comparing their respective activities. Towards this end, the two experimental studies presented in this ar...

Software development is a knowledge intensive activity. Software engineers need to gather domain knowledge to be able to successfully deliver a software system. In particular, novice software engineers need to acquire enough knowledge to perform their tasks. This means that knowledge transfer to novice software engineers must be quickly and effectively performed to facilitate the onboarding pro...

Novice drivers are over-represented in crashes involving turns across traffic at intersections and yet little is understood about the contributing factors. The current study proposed to explore the gap acceptance and turn time patterns of novice relative to experienced drivers when turning across traffic. Thirty novice and 30 experienced drivers each carried out a series of trials in a driving ...
