No full textEvaluation of e-Learning Activities: A Participant-Based Approach
No full textIn the Information Society, e-learning is one of the most valuable strategy for education, which effectively can support “lifelong learning”. Although in the last years several systems and methodologies have been proposed for e-learning, the evaluation of an e-learning process is still today a very complex task, which involves in a cooperative way many stakeholders, each one with a specific skill and experience.
In this paper, the main characteristics of an e-learning process are analysed and an effective participant-based framework for the evaluation of e-learning activities is presented. The framework uses a feedback-based strategy for the continuous evaluation of the e-learning process, by which evaluation is considered as a part of each phase of an e-learning activity.
The experimental results show that the proposed approach allows the creation of a positive e-learning environment
Allergy and Dry Eye Disease
No full textOcular allergy (OA) and dry eye disease (DED) are the most common ocular surface disorders with a potential severe impact on the patient’s quality of life. OA and DED may coexist and have a significant clinical overlap. Therefore, clinical features commonly believed to be distinctive of OA or DED may be sometimes insufficient for a differential diagnosis. Alterations of the tear film, epithelial barrier, and corneal innervation are described in OA and can pave the way to DED. Conversely, DED may facilitate or worsen allergic reactions in predisposed (atopic) patients. For these reasons, OA and DED should be considered as reciprocal predisposing conditions that share ocular surface inflammation as a common background
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
E-learning at the University: an Experimental Investigation
No full textIn the Information Society e-learning represents a powerful approach to knowledge dissemination since e-learning systems allow to create didactic contents and to distribute them without space and time constraints.
Universities are certainly the most important institutions involved in e-learning applications. Furthermore, in the Universities relevant investments have been done and many projects have been realized. To this goal, several aspects need to be still analyzed and several difficulties are waiting for acceptable solutions, like those concerning cultural, economical and political aspects that strongly effect the motivations of teachers in adopting e-learning systems and methodologies.
In this paper, the e-learning advancements carried out at the University of Bari are presented and some issues concerning teacher interests, needs and expectations are investigated. For this purpose, a on-line questionnaire has been produces and responses are analyzed and discussed
