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
Supporting Urban Innovators’ Reflective Practice
No full textOver the past years, a growing number of local initiatives are generating solutions for societal challenges in their cities. However, the scale and complexity of these challenges force urban innovators to constantly adapt and learn, having to acquire new capabilities that will help them advance towards systemic change. In the current work, we take the premise that these urban innovators need to be able to utilise the urban context as a learning ecosystem in order to push their interventions beyond the boundaries of small innovative niches. In keeping with Schön’s reflective practice, we envisage reflection as a core competence for these urban change makers to grow and present a reflective process supporting urban innovators in framing their professional learning journey to succeed in their projects. A series of online sessions have been conducted to investigate how to scaffold a reflective process enabling innovators to better identify challenges in their projects and the corresponding capabilities they need to acquire. In the proposed paper, we present reflective activities as a tool supporting urban innovators in self-defining their learning journeys and elaborate on the insights gained. It can be concluded that the reflective process we developed was valuable to urban innovators in unveiling new learning needs for their projects, while further research is needed to more effectively translate these learnings into actionable steps to sustain innovators’ self-development.Accepted Author ManuscriptDesign Conceptualization and Communicatio

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
Community pacts and we4SLE as tools to support the implementation of Smart Learning Ecosystems
No full textThis article describes and discusses the conditions under which starting from the Italian school system it would be possible to develop smart learning ecosystems. In particular, we focus on the so-called community pact—an opportunity recently introduced and promoted by the Ministry of Education—and on how dedicated technologies may support it. Starting from the description of the regulatory context and the consultation of teachers/students/territorial stakeholders, we illustrate the needs and motivations that led to the design and development of a web portal, we4SLE, which aims at fostering and facilitating: (a) the development of the identity and the increase of the internal cohesion of the community of reference; (b) the cultural growth of the students, also as future active citizens. Among the objectives of the web portal: provide an overview of the available resources, as well as methods for finding those necessary to implement the various initiatives; highlight the contribution made by the members of the community and give adequate visibility to the path of growth of each individual; support the strengthening of existing relationships in the community and encouraging the establishment of new ones; foster awareness about the community’s state of development through a participatory approach to its evaluation

Unit-level test adequacy criteria for visual dataflow languages and a testing methodology
No full textVisual dataflow languages (VDFLs), which include commercial and research systems, have had a substantial impact on end-user programming. Like any other programming languages, whether visual or textual, VDFLs often contain faults. A desire to provide programmers of these languages with some of the benefits of traditional testing methodologies has been the driving force behind our effort in this work. In this article we introduce, in the context of prograph, a testing methodology for VDFLs based on structural test adequacy criteria and coverage. This article also reports on the results of two empirical studies. The first study was conducted to obtain meaningful information about, in particular, the effectiveness of our all-Dus criteria in detecting a reasonable percentage of faults in VDFLs. The second study was conducted to evaluate, under the same criterion, the effectiveness of our methodology in assisting users to visually localize faults by reducing their search space. Both studies were conducted using a testing system that we have implemented in Prograph's IDE.Agrawal H., 1995, Proceedings.

Authorship Attribution in Less-Resourced Languages: A Hybrid Transformer Approach for Romanian
No full textAuthorship attribution for less-resourced languages like Romanian, characterized by the scarcity of large, annotated datasets and the limited number of available NLP tools, poses unique challenges. This study focuses on a hybrid Transformer combining handcrafted linguistic features, ranging from surface indices like word frequencies to syntax, semantics, and discourse markers, with contextualized embeddings from a Romanian BERT encoder. The methodology involves extracting contextualized representations from a pre-trained Romanian BERT model and concatenating them with linguistic features, selected using the Kruskal–Wallis mean rank, to create a hybrid input vector for a classification layer. We compare this approach with a baseline ensemble of seven machine learning classifiers for authorship attribution employing majority soft voting. We conduct studies on both long texts (full texts) and short texts (paragraphs), with 19 authors and a subset of 10. Our hybrid Transformer outperforms existing methods, achieving an F1 score of 0.87 on the full dataset of the 19-author set (an 11% enhancement) and an F1 score of 0.95 on the 10-author subset (an increase of 10% over previous research studies). We conduct linguistic analysis leveraging textual complexity indices and employ McNemar and Cochran’s Q statistical tests to evaluate the performance evolution across the best three models, while highlighting patterns in misclassifications. Our research contributes to diversifying methodologies for effective authorship attribution in resource-constrained linguistic environments. Furthermore, we publicly release the full dataset and the codebase associated with this study to encourage further exploration and development in this field

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
