Application of Particle Swarm Optimization to Formative E-Assessment in Project Management
No full textThe current paper describes the application of Particle Swarm Optimization algorithm to the formative e-assessment problem in project management. The proposed approach resolves the issue of personalization, by taking into account, when selecting the item tests in an e-assessment, the following elements: the ability level of the user, the targeted difficulty of the test and the learning objectives, represented by project management concepts which have to be checked. The e-assessment tool in which the Particle Swarm Optimization algorithm is integrated is also presented. Experimental results and comparison with other algorithms used in item tests selection prove the suitability of the proposed approach to the formative e-assessment domain. The study is presented in the framework of other evolutionary and genetic algorithms applied in e-education.Particle Swarm Optimization, Genetic Algorithms, Evolutionary Algorithms, Formative E-assessment, E-education

The morbidity and mortality associated with them are highest in intensive care units, but their effects are identifiable in virtually any medical department. Information about hospital-acquired infections, especially about their preventive measures, are rarely presented nowadays in a correct fashion to patients. This article aims to present, in a structured manner, the theoretical and practical aspects related to disclosure of hospital-acquired infections–related information to patients and its importance in preventing their spread. We will analyze both the conceptual framework for disclosing medical information related to nosocomial infections (autonomy, veracity, social justice, the principle of double effect, the precautionary principle, and nonmaleficence) and the practicalities regarding the disclosure of proper information to patients. Keywords: informed consent, nosocomial infections, respect for autonomy, social justice, preventio
TOWARDS FORMATIVE E-ASSESSMENT IN PROJECT MANAGEMENT THROUGH PERSONALIZED AUTOMATED FEEDBACK
No full textFormative e-assessment is a complex process, in which learners can build their knowledge, fill up their knowledge gaps or increase their learning abilities. The feedback mechanism is considered to be highly important for the formative dimension of e-assessment. Current paper proposes a model for automated feedback in a project management e-assessment environment: the model blends a built-in feedback sheet (a document containing the correct answers) with a recommender engine, which searches the web for references related to the incorrectly answered questions. The feedback model is personalized, because the web search is made taking into account the user profile: the list of concepts which weren’t correctly understood. This list of concepts is mapped on project management domain ontology.e-assessment, project management, automated feedback, ontology, knowledge system

No full textThe current economy is granting a widely interest to any activities involving knowledge. In the recent years, the number of the so-called knowledge-based organizations has reached a phenomenal rate of growth. Along with knowledge organizations, knowledge management started to play an important role in building the business strategy. Current paper identifies the knowledge gaps which threaten companies’ existence and underlines some knowledge tools based on competency-models to mitigate these gaps. Some statistical measurements for quantifying the strategic impact of using such intelligent tools are also described.knowledge, management, enterprises, crisis, competences

A Tool for Adaptive E-Assessment of Project Management Competences
No full textThis chapter proposes an e-assessment method for project management competences, using the computer adaptive testing (CAT) principle. Competences are represented using concept space graphs. The proposed model increases the tests configurability by considering several knowledge constraints when an item is selected. The proposed model is also seen as a self-directed-learning-tool, useful in the preparation process for project management certifications. The model is validated by comparison with an existing e-assessment tool, used for simulation purposes; statistic results are presented and analyzed. Although the initial level of knowledge of each user has a great impact on the final results obtained by that user, preparation with the proposed e-assessment method proved to be more efficient.</jats:p
