Visualising maritime vessel open data for better situational awareness in ice conditions
2018
Situational awareness of maritime vessels in ice conditions is important for the operation of supply chains. In the artic sea areas, the ice conditions pose a major challenge for maritime vessels getting stuck in the ice and being significantly delayed in arrival to harbor. Data science and open data provide new opportunities to overcome these challenges. This paper introduces available open data sources and data visualizations that can be used to develop applications, for example, for detecting maritime vessel collision, predicting estimated time of arrival to harbor, as well as maritime vessel route optimization in ice conditions. The paper begins by introducing available open data source…
Looking for Peace of Mind? Manage your (Technical) Debt : An Exploratory Field Study
2017
Background: In the last two decades Technical Debt (TD) has received a considerable amount of attention from software engineering research and practice. Recently, a small group of studies suggests that, in addition to its technical and economic consequences, TD can affect developers’ psychological states and morale. However, until now there has been a lack of empirical research clarifying such influences. Aims: In this study, we aim at taking the first step in filling this gap by investigating the potential impacts of TD and its management on developers’ morale. Method: Drawing from previous literature on morale, we decided to explore the influence of TD and its management on three dimensio…
Social support in the workplace for physicians in specialization training
2018
ABSTRACT When becoming a specialist, learning-through-service plays a significant role. The workplace affords good opportunities for learning, but the service-learning period may also impose stress on phycisians in specialization training. In medical work, social support has proved to be a very important factor in managing stress. Social support may afford advantages also for learning and professional identity building. However, little was known about how social support is perceived by doctors in specialization training. This study aimed to understand the perceptions of physicians in specialization training regarding social support communication in their workplace during their learning-thro…
Diversity begets diversity: A global perspective on gender equality in scientific society leadership.
2018
Research shows that gender inequality is still a major issue in academic science, yet academic societies may serve as underappreciated and effective avenues for promoting female leadership. That is, society membership is often self-selective, and board positions are elected (with a high turnover compared to institutions)—these characteristics, among others, may thus create an environment conducive to gender equality. We therefore investigate this potential using an information-theoretic approach to quantify gender equality (male:female ratios) in zoology society boards around the world. We compare alternative models to analyze how society characteristics might predict or correlate with the …
Does corn market uncertainty impact the US ethanol prices?
2018
The growing interest in biofuel as a green energy source has intensified the linkages between corn and ethanol markets, especially in the United States that represents the largest producing and exporting country for ethanol in the world. In this study, we examine the effect of corn market uncertainty on the price changes of US ethanol applying a set of GARCH-jump models. We find that the US ethanol price changes react positively to the corn market volatility shocks after controlling for the effect of oil price uncertainty. In addition, we document that the impact of corn price volatility on the US ethanol prices appears to be asymmetric. Specifically, only the positive corn market volatilit…
Design of mobile phones for older adults : An empirical analysis of design guidelines and checklists for feature phones and smartphones
2017
Design guidelines and checklists are suggested as a useful tool in the development and evaluation of interface design of mobile phones for older adults. Given the intense evolution of mobile phone design, understanding how the design guidelines and checklists have taken into account the advances in mobile phone usability for older adults is important for their correct application and future development. Thus, this study explores the usability dimensions of mobile phone design for older adults and the related changes in terms of time and the type of device (feature phones vs. smartphones) based on an expert coding of the eight mobile phone design guidelines and checklists for older adults pu…
Teacher beliefs on the significance of technology in education : the influence for inclusion in the andalusian teaching centers
2014
Este trabajo muestra resultados parciales de un Proyecto I+D de Ministerio de Ciencia y Tecnología español sobre centros TICs andaluces y sus repercusiones en los procesos de enseñanza-aprendizaje. Nos planteamos mediante encuesta indagar en las creencias del profesorado sobre la tecnología en la educación, su influencia en los procesos de aula. Los datos obtenidos nos aportan indicios que nos aproximan a la hipótesis inicial, confirmando parcialmente que las creencias que el profesorado tiene sobre el significado de las tecnologías en la educación se encuentran relacionadas con su frecuencia y uso, sus percepciones sobre la integración organizativa y curricular, y con su formación y capaci…
RIE : revista de investigación educativa
2020
Las tecnologías de la información y de la comunicación (TIC) suponen un cambio en los modos de aprendizaje del alumnado universitario. El propósito de este estudio es conocer la relación entre los enfoques de aprendizaje (superficial y profundo), el uso de las TIC (uso personal, uso académico no escolar y uso académico en el aula) y las competencias TIC (tecnológicas, pedagógicas y éticas) en alumnado universitario de titulaciones de Educación. Se trata de un estudio basado en un diseño correlacional, cuya muestra la constituyen 485 estudiantes de las titulaciones de grado de Pedagogía y de Educación Social de la Universidad de Valencia, seleccionados mediante un muestreo no probabilístico …
Analysis of the perceived self-‐efficacy in the use of ICT of pre-‐ service primary and preschool teachers
2017
La formación del profesorado en el uso de las TIC es un aspecto importante para conseguir una verdadera integración de las TIC en la educación. Según el modelo TPACK, esta formación no debe limitarse a contemplar de manera separada los aspectos relacionados con las TIC, el contenido curricular y la metodología. En el presente estudio se explora la percepción de autoeficacia en cuanto al uso de las TIC en el aula de una muestra de 107 estudiantes de los grados de Maestro/a en Educación Infantil y en Educación Primaria. Para ello se emplea una traducción del cuestionario para la autoevaluación de las competencias TIC elaborado por Tondeur et al. (2016). Los resultados del estudio muestran que…
Educational innovation through ICTs in the university setting. What do students think of these practices?
2014
Aquest document vol donar a conèixer l'experiència duta a terme per un grup d'estudiants durant el desenvolupament d'un programa destinat a alumnes innovadors de la Universitat de València. La immersió actual de les tecnologies en tots els àmbits de la societat i en l'educació planteja noves incògnites sobre com es desenvolupen aquestes experiències educatives. El projecte presentat era enfocat als alumnes amb vista a desenvolupar un treball que relacionés les tecnologies de la informació i la comunicació (TIC) amb els contextos d'aprenentatge universitaris. Així, en l'article es presenten les experiències, vivències i conclusions a les quals s'ha arribat quan s'ha acabat el projecte.
