Area-Based Depth Estimation for Monochromatic Feature-Sparse Orthographic Capture

2018

With the rapid development of light field technology, depth estimation has been highlighted as one of the critical problems in the field, and a number of approaches have been proposed to extract the depth of the scene. However, depth estimation by stereo matching becomes difficult and unreliable when the captured images lack both color and feature information. In this paper, we propose a scheme that extracts robust depth from monochromatic, feature-sparse scenes recorded in orthographic sub-aperture images. Unlike approaches which rely on the rich color and texture information across the sub-aperture views, our approach is based on depth from focus techniques. First, we superimpose shifted …

Spreading of Competing Information in a Network

2020

We propose a simple approach to investigate the spreading of news in a network. In more detail, we consider two different versions of a single type of information, one of which is close to the essence of the information (and we call it good news), and another of which is somehow modified from some biased agent of the system (fake news, in our language). Good and fake news move around some agents, getting the original information and returning their own version of it to other agents of the network. Our main interest is to deduce the dynamics for such spreading, and to analyze if and under which conditions good news wins against fake news. The methodology is based on the use of ladder fermion…

Harnessing User Values to Understand Value Co-Creation and Co-Destruction in Augmented Reality Mobile Games

2021

This paper explores the phenomena of value co- creation and co-destruction in augmented reality (AR) mobile games. More specifically, we aim to achieve an in-depth understanding of value co-creation and co- destruction occurring in Pokémon GO and the user values underlying these occurrences. Service-dominant (S-D) logic provides our study with a lens for understanding users as active co-creators, co- destroyers, and determinants of value. Further, the means-end theory establishes users’ personal values and goals as the basis for service value determination. We uncover key values highlighted in users’ positive and negative gaming experiences through a qualitative content analysis of 43 in-de…

Using eye-tracking to assess sourcing during multiple document reading: A critical analysis

2018

During the last 15 years, there have been some efforts to extend the use of eye - tracking to researching reading in complex contexts, such as the reading of multiple documents. The research community involved in this extension has been interested in higher - order comprehensio n processes occurring in complex reading contexts, such as sourcing, defined as the processes of attending to, representing, evaluating, and using available or accessible information about the sources of textual content. In this article, we argue that exte nding eye - tracking research to investigate more complex reading contexts has been made without critically reflecting on its validity in those contexts . Specific…

Pre-service Primary Teachers' Scientific Knowledge and Attitudes towards Science Learning and Their Influence on the Understanding of the Nature of S…

2016

The present study focused on the knowledge about the nature of science and the question of the extent to which this knowledge could be explained by employing scientific knowledge, as well as attitudes towards science learning. We obtained data from 171 Spanish pre-service primary school teachers on their knowledge about: a) science concepts, b) science process skills, c) the nature of science (that was split into science construction and validation and the role and function of scientific models), and d) their attitudes towards science learning. Quantitative and qualitative analyses provided interesting results: a) there were significant correlations between any pair of scores of conceptual …

Staging Life — Interpretation of Life in Kierkegaard’s

2000

“Whether custom and social life in England is of the stuff of primieval rock or whether it consists in seams and glacial debris will become more and more apparent in the course of a few years. At times, the wanderer is overcome by a sensation comparable to that felt when climbing Rosstrappe [an elevation near Magdeburg in present-day Saxony-Anhalt], where the eye ascends over millions of seemingly loose chunks of slate”.1 These lines, published on the 21st of May, 1870 in the German newspaper Neue Preussische Zeitung by the observer Theodore Fontane, might seem, at first sight, to not be a matter of special interest to readers a century apart (unless we are interested in the literary styles…

Lazos entre lingüística e ideología desde un enfoque historiográfico (ss. XVI-XX)

2020

Los 17 trabajos reunidos en este volumen estudian, desde una óptica historiográfica, la manifestación explícita y/o implícita de ideologías en textos de carácter metalingüístico. Tomando como eje las relaciones entre lingüística e ideología y su proyección en el ámbito social, político o didáctico, se analiza aquí el contenido de obras gramaticales, lexicográficas y ortográficas, historias de lenguas, artículos periodísticos, discursos, manifiestos y otros escritos publicados en la horquilla comprendida entre los siglos XVI y XX. Aunque el grueso de los trabajos se articula en torno a textos sobre el español tanto en su variedad europea como americana, también se da aquí cabida a contribuci…

Media Effects on Positive and Negative Learning

2017

While educational science in the past mainly focused on students’ formal or intentional learning from courses, textbooks, or online tutorials in university contexts, communication science usually deals with ordinary citizens’ informal or unintentional learning from the mass media in everyday life. One of the general aims of the PLATO project is to bring these research traditions together. Therefore, this paper sums up research on media effects on positive and negative learning recently conducted; our studies show that media coverage is often biased and news media, therefore, contribute to negative as well as positive learning. Which kind of learning occurs, heavily depends on the way inform…

Racialization, Othering, and Coping Among Adult International Adoptees in Finland

2015

This qualitative interview study examined experiences of racialization and coping among 14 adult international adoptees in Finland. The results show that adoptees encounter a range of racializations by which they are made ‘other’ and excluded from Finnishness. Racialization mostly occurs indirectly and subtly, and often by significant others, and consequently is more difficult to cope with. The findings suggest that the Finnish adoption community and adoption research should pay more attention to experiences of racialization among adoptees and take notice of the context-specific nature of coping when supporting adoptees to develop strategies that reduce discrimination and protect their well…
