University teaching and ICT. Materials online for training Cmap Tools
2013
En estas páginas presentamos una serie de materiales creados en un proyecto de elaboración de material de formación del profesorado universitario convocado por el Servicio de Formación Permanente de la Universitat de València. El objetivo fundamental del proyecto ha sido la creación de materiales en línea para aprender el funcionamiento del software libre Cmap Tools, elaborado por el Florida Institute for Human & Machine Cognition (IHMC). Los materiales de formación, desarrollados en la primera parte del proyecto, han consistido básicamente en la creación de vídeo tutoriales que muestran el procedimiento de descarga, instalación y las distintas utilidades del software y su aplicación a la d…
Concepts, proto-concepts, and shades of reasoning in neural networks
2019
One of the most important functions of concepts is that of producing classifications; and since there are at least two different types of such things, we better give a preliminary short description of them both. The first kind of classification is based on the existence of a property common to all the things that fall under a concept. The second, instead, relies on similarities between the objects belonging to a certain class A and certain elements of a subclass AS of A, the so-called ‘stereotypes.’ In what follows, we are going to call ‘proto-concepts’ all those concepts whose power of classification depends on stereotypes, leaving the term ‘concepts’ for all the others. The main aim of th…
Analysing Intercultural Dialogue Through Conceptual Densities
2020
In this chapter, we exemplify our methodological approach to analysing ‘densities’ of interrelated concepts in European education policy documents. We scrutinize instances where many of the core concepts of intercultural dialogue appear in the documents at the same time. Four core educational themes and four longer excerpts from the selected policy documents are examined in more detail. The chosen documents deal especially with multilingualism, migration, history teaching, and lifelong learning. The analysis of the conceptual densities in the chosen excerpts indicates how the meanings of intercultural dialogue are constructed through the conceptual frameworks and co-occurrences of their cor…
Teaching and Learning School Informatics: A Concept-Based Pedagogical Approach
2009
While informatics is a well-established discipline in higher education around the world, it is not the case in secondary education, with the exception of a few countries. Generally, what is taught is not informatics as a subject with its own methods, concepts, and principles, but some software tools with the goal that the use is sufficient for students to acquire skills. In addition, an analysis of the current situation reveals that the real competencies of teachers and students in informatics are far weaker than might be expected in secondary education. This work proposes a concept-based pedagogical approach to school informatics. The aim is to provide the students with a more thorough und…
More than experience? On the unique opportunities of virtual reality to afford a holistic experiential learning cycle
2021
Virtual reality has been proposed as a promising technology for higher education since the combination of immersive and interactive features enables experiential learning. However, previous studies did not distinguish between the different learning modes of the four-stage experiential learning cycle (i.e., concrete experience, reflective observation, abstract conceptualization, and active experimentation). With our study, we contribute a deeper understanding of how the unique opportunities of virtual reality can afford each of the four experiential learning modes. We conducted three design thinking workshops with interdisciplinary teams of students and lecturers. These workshops resulted in…
Identity and Agency in Professional Learning
2014
This chapter elaborates professional learning from two complementary perspectives, namely professional identity and agency. Starting with the conceptualization of identity and agency, the chapter illustrates how professional identity and agency are intertwined with workplace learning at the individual and social levels. In theoretical terms we adhere to a subject-centred socio-cultural approach. This implies that professional learning is seen as a dual process, involving identity negotiation and the development of work practices (including the practice of agency), with both aspects taking place within the socio-cultural and material conditions of the workplace. We see professional identity …
Arabic Named Entity Recognition: A Feature-Driven Study
2009
The named entity recognition task aims at identifying and classifying named entities within an open-domain text. This task has been garnering significant attention recently as it has been shown to help improve the performance of many natural language processing applications. In this paper, we investigate the impact of using different sets of features in three discriminative machine learning frameworks, namely, support vector machines, maximum entropy and conditional random fields for the task of named entity recognition. Our language of interest is Arabic. We explore lexical, contextual and morphological features and nine data-sets of different genres and annotations. We measure the impact …
Conditioned orienting (alpha) and delayed behavioral and evoked neural responses during classical conditioning
1989
A differentiation of short-latency (alpha) and long-latency (delayed) classically conditioned behavioral and evoked neural (hippocampal) responses was attempted. Further, facilitation and retardation of these responses were studied in an experimental design in which 10 paired conditioning sessions either preceded (CC-CO group) or followed (CO-CC group) 10 randomly unpaired presentations of conditioned stimuli (CS) and unconditioned stimuli (UCS). A 2024-ms tone (1000 Hz) was delivered directly through a miniature earphone to the left ear, eliciting an orienting head movement ('alpha' response) to the left. The unconditioned stimulus (UCS) was a direct 1024-ms stimulation of the lateral hypo…
It’s a matter of confidence. Institutions, government stability and economic outcomes
2021
In this paper we analyse the effect of constitutional structures over policy outcomes. In particular, we exploit the heterogeneity in parliamentary systems deriving from the presence and the use of the confidence vote to investigate whether stable and unstable parliamentary systems behave differently in terms of the policies they implement. This finer partition of parliamentary systems allows us to identify effects that are more robust than the ones previously discussed in the literature. We show that the difference between presidential and parliamentary systems documented in previous works is driven by a difference between presidential and stable parliamentary systems. We suggest that poss…
Motion Artifact Detection in Confocal Laser Endomicroscopy Images
2018
Confocal Laser Endomicroscopy (CLE), an optical imaging technique allowing non-invasive examination of the mucosa on a (sub)- cellular level, has proven to be a valuable diagnostic tool in gastroenterology and shows promising results in various anatomical regions including the oral cavity. Recently, the feasibility of automatic carcinoma detection for CLE images of sufficient quality was shown. However, in real world data sets a high amount of CLE images is corrupted by artifacts. Amongst the most prevalent artifact types are motion-induced image deteriorations. In the scope of this work, algorithmic approaches for the automatic detection of motion artifact-tainted image regions were develo…
