Explorando la divulgación de información integrada por universidades colombianas. Un análisis de páginas web basado en el marco del IIRC
2021
La información integrada se presenta como un fenómeno de reciente auge que permite a diversas organizaciones informar de una manera simplificada pero completa sobre su gestión respecto a diversos tipos de capitales. Aunque predominantemente se ha desarrollado en las empresas privadas, en el ámbito internacional viene reconociéndose que otro tipo de organizaciones como las universidades, divulgan esta información o cuentan con la necesidad y el potencial para ello. Este trabajo tiene como objetivo analizar en qué medida la información solicitada para construir un reporte integrado de acuerdo con los requerimientos del Marco Conceptual del IIRC, ya está revelada en internet por las universida…
Entrepreneurial universities: A bibliometric analysis within the business and management domains
2021
Abstract This study presents a bibliometric analysis of scientific publications investigating entrepreneurial universities in the business and management fields. The authors collected 511 documents from the Web of Science and analysed them using Bibliometrix, an RStudio package for performance analysis and science mapping. The study aims to provide an overview of the evolution of research about this topic and describe the structures (i.e., conceptual, social, and intellectual) characterising it. It discusses the results to identify the main areas addressed so far and highlight gaps in the literature, offering avenues for possible future research. The results show that publications on entrep…
Intrapreneurs: Characteristics and Behavior
2017
Intrapreneurship has become a relevant topic in literature as far as its impact on organizational performance is more and more often highlighted from very diverse points of view. The main goal of this chapter is introducing the specific personal and professional profile of intrapreneurs, considered as highly committed individuals motivated by innovation, continuous improvement and able to leader teams in the direction they foresee within the companies in which they work. This chapter will present the relevance and impact of intrapreneurship, the role and main characteristics of the intrapreneurs, their behavior and motivations, and finally some good practices will be exposed in order to enc…
A Barrier Framework for open E-Learning in public administrations
2015
A comprehensive literature review on E-Learning and OER in public administrations.A contextualized Barrier Framework about core barriers in the public sector.Lessons learned to improve implementation and adoption processes of open E-Learning.The relevance of organizational, social and technical barriers in the public sector. E-Learning and openness in education are receiving ever increasing attention in businesses as well as in academia. However, these practices have only to small extent been introduced in public administrations. The study addresses this gap by presenting a literature review on Open Educational Resources OER and E-Learning in the public sector. The main goal of the article …
FCA-based knowledge representation and local generalized linear models to address relevance and diversity in diverse social images
2019
Abstract In social image retrieval, the main goal is to offer a relevant but also diverse result set of images to the user. To address relevance and diversity at the same time, we propose a multi-modal procedure. This approach deals with the diversification problem using a two-step procedure based on the application of Formal Concept Analysis (FCA) to organize the text content of the images, followed by a Hierarchical Agglomerative Clustering (HAC) step to find the topics addressed by the images. FCA detects the latent concepts covered by the images in the result set, organizing them according to these concepts. In the second step, clustering is carried out to group together the ones with a…
Teacher education programmes in physical education and sport at master’s level: Opportunities and challenges
2021
I denne artikkelen undersøker vi fremtidige muligheter og utfordringer i femårige lærerutdanninger i kroppsøving og idrettsfag på masternivået, i lys av kvalitet og relevans for fagfeltet. I undersøkelsen ble det benyttet en kvalitativ tilnærming med to metodiske innganger. Først ble et utvalg på 96 masteroppgaver i perioden 2015–2018 innenfor fagfeltet kroppsøving og idrettsfag brukt for å undersøke hva slags tematikker, teoretiske tilnærminger og metoder som er benyttet i masteroppgavene. Med bakgrunn i denne undersøkelsen ble det gjennomført en workshop med et utvalg lærerutdannere for å få innsikt i hva de oppfattet som fremtidige muligheter og utfordringer i femårig lærerutdanning i fa…
Feature Ranking of Large, Robust, and Weighted Clustering Result
2017
A clustering result needs to be interpreted and evaluated for knowledge discovery. When clustered data represents a sample from a population with known sample-to-population alignment weights, both the clustering and the evaluation techniques need to take this into account. The purpose of this article is to advance the automatic knowledge discovery from a robust clustering result on the population level. For this purpose, we derive a novel ranking method by generalizing the computation of the Kruskal-Wallis H test statistic from sample to population level with two different approaches. Application of these enlargements to both the input variables used in clustering and to metadata provides a…
A Simple Solution for Improving the Effectiveness of Traditional Information Retrieval Systems
2005
In this paper we present a system based on the LSA paradigm to improve the performance of a traditional information retrieval system. The proposed system aims to improve both the recall and the precision capabilities of traditional search engines thanks to a semantic query expansion and a subsequent semantic results filtering. A collection of 650 documents has been used to compare the performances of the proposed system with a traditional search engine. Experimental trials show the effectiveness of the proposed solution
Seasonal Mapping of Irrigated Winter Wheat Traits in Argentina with a Hybrid Retrieval Workflow Using Sentinel-2 Imagery
2022
Earth observation offers an unprecedented opportunity to monitor intensively cultivated areas providing key support to assess fertilizer needs and crop water uptake. Routinely, vegetation traits mapping can help farmers to monitor plant development along the crop’s phenological cycle, which is particularly relevant for irrigated agricultural areas. The high spatial and temporal resolution of the Sentinel-2 (S2) multispectral instrument leverages the possibility to estimate leaf area index (LAI), canopy chlorophyll content (CCC), and vegetation water content (VWC) from space. Therefore, our study presents a hybrid retrieval workflow combining a physically-based strategy with a machine learni…
Design, development and validation of a system for automatic help to medical text understanding
2020
Abstract Objective The paper presents a web-based application, SIMPLE, that facilitates medical text comprehension by identifying the health-related terms of a medical text and providing the corresponding consumer terms and explanations. Background The comprehension of a medical text is often a difficult task for laypeople because it requires semantic abilities that can differ from a person to another, depending on his/her health-literacy level. Some systems have been developed for facilitating the comprehension of medical texts through text simplification, either syntactical or lexical. The ones dealing with lexical simplification usually replace the original text and do not provide additi…
