EduCOR: An Educational and Career-Oriented Recommendation Ontology

With the increased dependence on online learning platforms and educational resource repositories, a unified representation of digital learning resources becomes essential to support a dynamic and multi-source learning experience. We introduce the EduCOR ontology, an educational, career-oriented ontology that provides a foundation for representing online learning resources for personalised learning systems. The ontology is designed to enable learning material repositories to offer learning path recommendations, which correspond to the user’s learning goals and preferences, academic and psychological parameters, and labour-market skills. We present the multiple patterns that compose the EduCOR ontology, highlighting its cross-domain applicability and integrability with other ontologies. A demonstration of the proposed ontology on the real-life learning platform eDoer is discussed as a use case. We evaluate the EduCOR ontology using both gold standard and task-based approaches. The comparison of EduCOR to three gold schemata, and its application in two use-cases, shows its coverage and adaptability to multiple OER repositories, which allows generating user-centric and labour-market oriented recommendations.

From paper maps to the Digital Earth and the Internet of Places

Maps have always been tools that have fascinated men, for their ability to make us see the world that surrounds us. They were and are the outcome of models and methods applied to the observation of the world, starting from geodesy, surveying photogrammetry and remote sensing. All these disciplines, which we now group under the new name of geomatics, have had a tremendous boost in recent years. However, the synergy with information computer technology is probably the aspect that is revolutionizing more cartography. Earlier computers and after the Internet have brought us to new concepts and tools that will have profound effects not only in the world of niche of cartographers, but also more generally in the life of all human beings. The Digital Earth, proposed in 1998 by Al Gore, has been enriched in just twenty years of a set of new demands, which make even more interesting and challenging being cartographers today. The paper, without claiming to be comprehensive, aims at providing a concise overview of the state of art and of the advancement in this area. Moreover, it urges the community of geomatics to be protagonist and promoter of a new cartography, largely to be reinvented, and that would put us at the center of processes of knowledge and management of the Earth. The map makers in the past helped discovering new worlds, now the challenge is to rediscover our common world with new eyes of environmental, social, economic equity, sustainability and participation

DIGITALIZAÇÃO DO ENSINO SUPERIOR: IMPACTOS NAS PRÁTICAS DE GESTÃO E DESENVOLVIMENTO INSTITUCIONAL. UMA REVISÃO DE LITERATURA

For an extended period, the higher education community has been diligently endeavoring to implement technologically advanced and more efficacious methodologies. The aim is to enhance effectiveness and cultivate a generation of graduates equipped to navigate the evolving labor market dynamics and adapt to the influences of globalization. The outbreak of the Covid-19 pandemic significantly catalyzed the adoption of digital education, often referred to as "E-Learning," as a predominant mode of instruction across a majority of countries. This shift was necessitated by the imperative to adhere to social distancing measures and prevent the potential collapse of the educational infrastructure. In the wake of this transformative paradigm, educational institutions were compelled to engineer inventive management approaches to effectively traverse this altered landscape, marking the dawn of a new era. This era is characterized by a profound dependence on advanced technology and unfettered information accessibility as pivotal factors for sustaining and optimizing performance.This paper aims to explain the basic ideas behind managing higher education while exploring the existing research that supports these ideas. By breaking down the various aspects and tools involved, the goal is to shed light on the complex nature of managing higher education. This exploration eventually leads to an examination of how the digitalization of education impacts different functional areas of education management. Through this in-depth analysis, a clear connection emerges between the need for digitalization and the necessity to update management systems. This connection is crucial for not only achieving but also sustaining effective operation in this new era that combines technology and education.Durante um longo período, a comunidade do ensino superior tem-se esforçado diligentemente por implementar metodologias tecnologicamente avançadas e mais eficazes. O objetivo é aumentar a eficácia e cultivar uma geração de licenciados equipados para navegar na dinâmica do mercado de trabalho em evolução e adaptar-se às influências da globalização. O surto da pandemia de Covid-19 catalisou significativamente a adoção da educação digital, muitas vezes referida como "E-Learning", como um modo predominante de ensino na maioria dos países. Esta mudança foi necessária devido ao imperativo de aderir a medidas de distanciamento social e evitar o potencial colapso da infraestrutura educativa. Na sequência deste paradigma transformador, as instituições de ensino foram obrigadas a conceber abordagens de gestão inventivas para atravessar eficazmente esta paisagem alterada, marcando o início de uma nova era. Esta era caracteriza-se por uma profunda dependência da tecnologia avançada e da acessibilidade ilimitada à informação como factores essenciais para sustentar e otimizar o desempenho. Este documento tem por objetivo explicar as ideias básicas subjacentes à gestão do ensino superior, explorando simultaneamente a investigação existente que apoia estas ideias. Ao decompor os vários aspectos e instrumentos envolvidos, o objetivo é esclarecer a natureza complexa da gestão do ensino superior. Esta exploração acaba por conduzir a um exame da forma como a digitalização do ensino afecta as diferentes áreas funcionais da gestão do ensino. Através desta análise aprofundada, surge uma ligação clara entre a necessidade de digitalização e a necessidade de atualizar os sistemas de gestão. Esta ligação é crucial não só para alcançar, mas também para manter um funcionamento eficaz nesta nova era que combina tecnologia e educação

Selected heterozygosity at cis-regulatory sequences increases the expression homogeneity of a cell population in humans

Background: Examples of heterozygote advantage in humans are scarce and limited to protein-coding sequences. Here, we attempt a genome-wide functional inference of advantageous heterozygosity at cis-regulatory regions. Results: The single-nucleotide polymorphisms bearing the signatures of balancing selection are enriched in active cis-regulatory regions of immune cells and epithelial cells, the latter of which provide barrier function and innate immunity. Examples associated with ancient trans-specific balancing selection are also discovered. Allelic imbalance in chromatin accessibility and divergence in transcription factor motif sequences indicate that these balanced polymorphisms cause distinct regulatory variation. However, a majority of these variants show no association with the expression level of the target gene. Instead, single-cell experimental data for gene expression and chromatin accessibility demonstrate that heterozygous sequences can lower cell-to-cell variability in proportion to selection strengths. This negative correlation is more pronounced for highly expressed genes and consistently observed when using different data and methods. Based on mathematical modeling, we hypothesize that extrinsic noise from fluctuations in transcription factor activity may be amplified in homozygotes, whereas it is buffered in heterozygotes. While high expression levels are coupled with intrinsic noise reduction, regulatory heterozygosity can contribute to the suppression of extrinsic noise. Conclusions: This mechanism may confer a selective advantage by increasing cell population homogeneity and thereby enhancing the collective action of the cells, especially of those involved in the defense systems in humansope

Personalised trails and learner profiling within e-learning environments

This deliverable focuses on personalisation and personalised trails. We begin by introducing and defining the concepts of personalisation and personalised trails. Personalisation requires that a user profile be stored, and so we assess currently available standard profile schemas and discuss the requirements for a profile to support personalised learning. We then review techniques for providing personalisation and some systems that implement these techniques, and discuss some of the issues around evaluating personalisation systems. We look especially at the use of learning and cognitive styles to support personalised learning, and also consider personalisation in the field of mobile learning, which has a slightly different take on the subject, and in commercially available systems, where personalisation support is found to currently be only at quite a low level. We conclude with a summary of the lessons to be learned from our review of personalisation and personalised trails

OULDI-JISC Project Evaluation Report: the impact of new curriculum design tools and approaches on institutional process and design cultures

This report presents research and evaluation undertaken by the OULDI-JISC Project (Open University Learning Design Initiative JISC Project) between 2008 and 2012. In particular, it considers the impact of new curriculum design tools and approaches piloted by the project on institutional processes and design cultures. These tools and approaches include tools for sharing learning design expertise (Cloudworks), visualising designs (CompendiumLD, Module Map, Activity Profile) and for supporting design and reflection in workshops (Facilitation Cards, workshop activities, etc.). The project has adopted a learning design approach so as to help foreground pedagogy and learner experience. Nine pilots have been completed across six UK universities

Web Data Extraction, Applications and Techniques: A Survey

Web Data Extraction is an important problem that has been studied by means of different scientific tools and in a broad range of applications. Many approaches to extracting data from the Web have been designed to solve specific problems and operate in ad-hoc domains. Other approaches, instead, heavily reuse techniques and algorithms developed in the field of Information Extraction. This survey aims at providing a structured and comprehensive overview of the literature in the field of Web Data Extraction. We provided a simple classification framework in which existing Web Data Extraction applications are grouped into two main classes, namely applications at the Enterprise level and at the Social Web level. At the Enterprise level, Web Data Extraction techniques emerge as a key tool to perform data analysis in Business and Competitive Intelligence systems as well as for business process re-engineering. At the Social Web level, Web Data Extraction techniques allow to gather a large amount of structured data continuously generated and disseminated by Web 2.0, Social Media and Online Social Network users and this offers unprecedented opportunities to analyze human behavior at a very large scale. We discuss also the potential of cross-fertilization, i.e., on the possibility of re-using Web Data Extraction techniques originally designed to work in a given domain, in other domains.Comment: Knowledge-based System

Cognition and the Web

Empirical research related to the Web has typically focused on its impact to social relationships and wider society; however, the cognitive impact of the Web is also an increasing focus of scientific interest and research attention. In this paper, I attempt to provide an overview of what I see as the important issues in the debate regarding the relationship between human cognition and the Web. I argue that the Web is potentially poised to transform our cognitive and epistemic profiles, but that in order to understand the nature of this influence we need to countenance a position that factors in the available scientific evidence, the changing nature of our interaction with the Web, and the possibility that many of our everyday cognitive achievements rely on complex webs of social and technological scaffolding. I review the literature relating to the cognitive effects of current Web technology, and I attempt to anticipate the cognitive impact of next-generation technologies, such as Web-based augmented reality systems and the transition to data-centric modes of information representation. I suggest that additional work is required to more fully understand the cognitive impact of both current and future Web technologies, and I identify some of the issues for future scientific work in this area. Given that recent scientific effort around the Web has coalesced into a new scientific discipline, namely that of Web Science, I suggest that many of the issues related to cognition and the Web could form part of the emerging Web Science research agenda
