Los corpus discursivos orales como recurso didáctico: la oralidad a través del texto en contexto
2014
El presente trabajo atiende a la rentabilidad de los corpus discursivos orales como recurso didáctico en la clase de E/LE para los niveles B2 y C1. La explotación de estas muestras constituye una importante herramienta para que el estudiante desarrolle y mejore sus competencias comunicativas en E/LE. Gracias al empleo de corpus discursivos orales para la didáctica es posible ofrecer muestras reales producidas por nativos en diferentes contextos.
ASTEROIDS SEARCH RESULTS IN LARGE PHOTOGRAPHIC SKY SURVEYS
2017
Photographic observations of XX century contained numerous and varied information about all objects and events of the Universe fixed on plates. The original and interesting observations of small bodies of the Solar system in previous years can be selected and used for various scientific tasks. Existing databases and online services can help make such selection easily and quickly. The observations of chronologically earlier ppositions, photometric evaluation of brightness for long periods of time allow refining the orbits of asteroids and identifying various non-stationaries. Photographic observations of Northern Sky Survey project and observations of clusters …
Difficulties Perceived by ICU Nurses Providing End-of-Life Care: A Qualitative Study
2020
Background: With advances in medicine and technology, intensive care units (ICUs) have the capacity to treat patients who would have previously not been expected to survive and would therefore not have been managed in ICUs. When an individual is not expected to survive, doctors and nurses face the modern ethical dilemma of death associated with withdrawal of life-supporting strategies. The aim of this study was to identify difficulties perceived by ICU nurses providing end-of-life care (EOLC) in Poland. Methods: The qualitative study was designed to investigate the difficulties, and the related barriers, to EOLC provided in ICUs in Poland. We conducted individual telephone interviews with I…
Electrochemical Oxidation of Hf-Nb Alloys as a Valuable Route to Prepare Mixed Oxides of Tailored Dielectric Properties
2018
Metal oxides with high dielectric constant are extensively studied in the frame of substituting SiO2 as gate dielectric in nanoelectronic devices. Here, high-k mixed HfO2/Nb2O5 oxides are prepared by a facile electrochemical route starting from sputtering-deposited Hf–Nb alloys with several compositions. Transmission electron microscopy, grazing incidence X-ray diffraction, and glow discharge optical emission spectroscopy are employed to study the oxide structures, disclosing a crystalline–amorphous transition of the electrochemically prepared oxides by increasing the Nb content. Photo-electrochemical measurements allow the observation of optical transitions ascribed to localized states ins…
Testing a spectral-based feature set for audio genre classification
2011
Automatic musical genre classification is an important information retrieval task since it can be applied for practical purposes such as the organization of data collections in the digital music industry. However, this task remains an open question because the current state of the art shows far from satisfactory outcomes in terms of classification performance. Moreover, the most common algorithms that are used for this task are not designed for modelling music perception. This study suggests a framework for testing different musical features for use in music genre classification and evaluates the performance of this task based on two musical descriptors. The focus of this study is on automa…
Perceptions of digital technology in nursing education: A qualitative study.
2021
Abstract Aim The aim of this study was to explore how digital technologies can facilitate interactive learning in a 15-credit theory module on basic nursing. Background Digital platforms are in widespread use in nursing education; however, the rapid technological advancement provides new opportunities to support teaching and learning. This indicates the need to explore how educational digital technologies can be used as an integral part of learning activities to promote quality and relevance in nursing education. This study was carried out at the Department of Nursing Science at a university in Norway. The university has been using a digital platform for many years and has recently adopted …
Illusion of knowledge through Facebook news? Effects of snack news in a news feed on perceived knowledge, attitude strength, and willingness for disc…
2020
Abstract Research indicates that using social network sites as a source for news increases perceived knowledge even if, objectively, people fail to acquire knowledge. This might result from the frequent repetition of topics in news posts caused by multiple news outlets posting about the same news topics and the algorithm that favors similar postings. These repeated encounters can have a positive effect on the perception of knowing more, even if actual learning hardly occurs. An experiment (N = 810, representative of German Internet users) tested these assumptions. Participants were assigned to one of four groups and received a news feed with no information, few news posts, many news posts, …
Music as a mnemonic to learn gesture sequences in normal aging and Alzheimer’s disease
2014
Strong links between music and motor functions suggest that music could represent an interesting aid for motor learning. The present study aims for the first time to test the potential of music to assist in the learning of sequences of gestures in normal and pathological aging. Participants with mild Alzheimer's disease (AD) and healthy older adults (Controls) learned sequences of meaningless gestures that were either accompanied by music or a metronome. We also manipulated the learning procedure such that participants had to imitate the gestures to-be-memorized in synchrony with the experimenter or after the experimenter during encoding. Results show different patterns of performance for t…
Fintech strategy: E-reputation
2021
Digital media use applied to professional atmosphere is increasing its relevance in the companies of the 21st century. As a consequence, organisations should bear this fact in mind and adapt their corporate strategies to the new market demands. Online social networks offer customers the possibility to bring attention to issues they believe need to be addresses by organisations. Added to this, e-reputation plays a pivotal role in determining a company's competitive advantage. This paper studies the role of e-communications in an organisation's strategy and how analytics and modelling techniques are used to take advantage of the digital media content. It discusses the historical reputational …
