A Method for Designing Tools for Information Retrieval from Documents
1987
The paper describes an experimental document database language. It consists of document database extensions to Prolog. An extended Prolog is suitable for specifying, prototyping, and in some cases also for implementing information retrieval tools.
The Qualitative Researcher in the Quality of Life Field
2015
In the current society, there is a plurality of perspectives about the knowledge of the world and in that stage there is an expansion of the use of qualitative methods as expression of the contemporary interest in the subject-matters, considering the epistemological relevance acquired by the introduction of the subject’s word as a possibility to construct knowledge. The qualitative researcher is expected to feel personally involved in every step of the research process, because every consideration and decision will have to be based on entirely personal grounds. Thus, in this chapter, we shall look into the importance of the qualitative researcher’s leading role in each phase of the research…
Comparing motivational, self-regulatory and habitual processes in a computer-tailored physical activity intervention in hospital employees - protocol…
2017
Abstract Background Most people do not engage in sufficient physical activity to confer health benefits and to reduce risk of chronic disease. Healthcare professionals frequently provide guidance on physical activity, but often do not meet guideline levels of physical activity themselves. The main objective of this study is to develop and test the efficacy of a tailored intervention to increase healthcare professionals’ physical activity participation and quality of life, and to reduce work-related stress and absenteeism. This is the first study to compare the additive effects of three forms of a tailored intervention using different techniques from behavioural theory, which differ accordin…
Efecto del juego vs. el role-playing en la implicación de los participantes del Programa saludiversex
2021
El programa de educación afectivo sexual SALUDIVERSEX para personas con diversidad funcional intelectual (DFI) sienta sus bases sobre la importancia de la implicación activa de los participantes en las sesiones dirigidas a favorecer el aprendizaje de conocimientos, habilidades y actitudes saludables. Por ello, en las sesiones dedicadas a transmitir conocimientos sobre sexo/sexualidad, higiene sexual, prácticas sexuales y sexo seguro, así como, en las que se trabajan actitudes hacia la diversidad sexual y las relaciones de pareja se prioriza más el juego. Por otra parte, en las sesiones dedicadas a trabajar habilidades interpersonales se emplea fundamentalmente el role playing. El objetivo d…
Automatic mass spectra recognition for Ultra High Vacuum systems using multilabel classification
2021
Abstract In Ultra High-Vacuum (UHV) systems it is common to find a mixture of many gases originating from surface outgassing, leaks and permeation that contaminate vacuum chambers and cause issues to reach ultimate pressures. The identification of these contaminants is, in general, done manually by trained technicians from the analysis of mass spectra. This task is time consuming and can lead to misinterpretation or partial understanding of issues. The challenge resides in the rapid identification of these contaminants by using some automatic gas identification technique. This paper explores the automatic and simultaneous identification of 80 molecules, including some of the most commonly p…
Do graphical overviews facilitate or hinder comprehension in hypertext?
2009
Educational hypertexts usually include graphical overviews, conveying the structure of the text schematically with the aim of fostering comprehension. Despite the claims about their relevance, there is currently no consensus on the impact that hypertext overviews have on the reader's comprehension. In the present paper we have explored how hypertext overviews might affect comprehension with regard to (a) the time at which students read the overview and (b) the hypertext difficulty. The results from two eye-tracking studies revealed that reading a graphical overview at the beginning of the hypertext is related to an improvement in the participant's comprehension of quite difficult hypertexts…
All-atom simulations disentangle the functional dynamics underlying gene maturation in the intron lariat spliceosome
2018
The spliceosome (SPL) is a majestic macromolecular machinery composed of five small nuclear RNAs and hundreds of proteins. SPL removes noncoding introns from precursor messenger RNAs (pre-mRNAs) and ligates coding exons, giving rise to functional mRNAs. Building on the first SPL structure solved at near–atomic-level resolution, here we elucidate the functional dynamics of the intron lariat spliceosome (ILS) complex through multi-microsecond-long molecular-dynamics simulations of ∼1,000,000 atoms models. The ILS essential dynamics unveils (i) the leading role of the Spp42 protein, which heads the gene maturation by tuning the motions of distinct SPL components, and (ii) the critical particip…
EFFECTS OF CUSTOMER KNOWLEDGE MANAGEMENT AND CUSTOMER ORIENTATION ON INNOVATION CAPACITY AND MARKETING RESULTS IN SMEs: THE MEDIATING ROLE OF INNOVAT…
2018
Managing customer knowledge is a key of source for SMEs. The principal aim of this paper is to provide empirical evidence on the direct effects of two specific strategic resources: customer orientation and customer knowledge management (CKM), on innovation capacity and marketing results in SMEs. The study also examines the role of innovation orientation as a mediator between customer orientation and CKM. For this purpose, a structural model was proposed and tested through an empirical investigation with variance-based structural equation modeling (PLS) using a sample made up of 210 Spanish SMEs. The findings highlight the relevance of CKM and customer orientation as important strategic res…
Effects of Grade Retention Policies: A Literature Review of Empirical Studies Applying Causal Inference
2021
The identification of the causal effects of grade retention policies is of enormous relevance for researchers and policymakers alike. Taking advantage of the availability of more detailed longitudinal datasets, researchers have been able to apply different identification strategies that address the classical problems of selection bias and unobserved heterogeneity that have plagued previous studies on the effect of retention. We present a systematic literature review of empirical studies aiming to unveil the causal effects of retention. This study underlines the need to consider and evaluate different kinds of grade retention polices as their effects vary depending on several dimensions (suc…
Relevansen av trigonometri : En studie i to deler på relevansen av trigonometri for elever på videregående skole
2017
Masteroppgave matematikkdidaktikk MA502 – Universitetet i Agder 2017 The topic of this master’s thesis is the relevance of mathematics, especially the relevance of trigonometry. Many students ask the question “why do I need to learn about this”. The aim of this study was to give the students an answer to this question. In the research literature, I found that this question has to do with relevance, and that relevance is a connection between people, an activity and future goals. In particular, one needs to question: relevance of what? relevance according to whom? relevance for whom? And relevance to what end? The empirical part of my research consisted of two studies. In Study 1 the purpose …
