Three species new to the moss flora of Alaska
2022
Three moss species - Crossidium squamiferum, Didymodon tectorum and Loeskeobryum brevirostre - have been recorded as new to the Alaskan bryoflora. A brief description of the species and their ecology is given.
Comprensiones categoriales y subrecursión
2012
Se define una nueva estructura categorial con el objeto de caracterizar las clases de funciones subrecursivas pertenecientes a la Jerarquía de Grzegorzcyk. Ello se consigue por medio de functores de coerción sobre una categoría simétrica monoidal dotada de ciertos esquemas de recursión que imitan el esquema de recursión acotada. Ello se hace para dar una visión categorial generalizada de la recursión y la composición seguras. A new categorical setting is defined in order to characterize the subrecursive classes belonging to the Grzegorzcyk Hierarchy. This is achieved by means of coercion functors over a symmetric monoidal category endowed with certain recursion schemes that imitate the boun…

Elena+ Care for COVID-19, a Pandemic Lifestyle Care Intervention: Intervention Design and Study Protocol
2021
Background: The current COVID-19 coronavirus pandemic is an emergency on a global scale, with huge swathes of the population required to remain indoors for prolonged periods to tackle the virus. In this new context, individuals' health-promoting routines are under greater strain, contributing to poorer mental and physical health. Additionally, individuals are required to keep up to date with latest health guidelines about the virus, which may be confusing in an age of social-media disinformation and shifting guidelines. To tackle these factors, we developed Elena+, a smartphone-based and conversational agent (CA) delivered pandemic lifestyle care intervention.Methods: Elena+ utilizes varied…
Is it a tool or a toy? How user's conception of a system’s purpose affect their experience and use
2019
The boundary between hedonic and utilitarian information systems has become increasingly blurred during recent years due to the rise of developments such as gamification. Therefore, users may perceive the purpose of the same system differently, ranging from pure utility to pure play. However, in literature that addresses why people adopt and use information systems, the relationship between the users conception of the purpose of the system, and their experience and use of it has not yet been investigated. Therefore, in this study we investigate the interaction effects between users’ utility-fun conceptions of the system and the perceived enjoyment and usefulness from its use, on their post-…
Robomaths: Robotics to Learn Matematics in a Architecture Degree
2020
The abstract part of mathematics is a difficult matter included in many subjects in university degrees. Specifically, in architecture degrees students lack interest in this topic if they don’t experience its immediate application. In addition, technological skills are required at every educational level and the students of these degrees are usually more interested in art than in technology. With the aim of encouraging architecture students' interest in mathematics and technology, a methodology is presented here that includes the use of robotics in maths lectures. The key idea is to make the abstract part of mathematics understandable by means of robots.
In vitro synthesis of dopamine and noradrenaline in the isolated rat pineal gland: day-night variations and effects of electrical stimulation.
1989
: Isolated rat pineal glands were incubated in vitro in a medium containing [I4C]dopamine or [14C]tyrosine, and the tissue contents of l4C-labelled and total dopamine and noradrenaline were determined by HPLC followed by electrochemical detection and scintillation spectrometry. During incubation with [l4C]dopamine, the labelled amine accumulated in pineal glands and was partially converted into [l4C]noradrenaline. Nomifensine, a neuronal amine uptake blocker, largely inhibited the accumulation of [l4C]dopamine and the formation of [14C]noradrenaline. These experiments demonstrated dopamine β-hydroxylase activity in the sympathetic nerves of the pineal gland. During incubation with [14C]tyro…
Bibliometrics applied to gamification as a digital learning strategy
2019
Este trabajo se interesa por un tema de actualidad como es la gamificación en educación, una interesante estrategia didáctica para responder a los alarmantes datos sobre fracaso y abandono escolar obtenidos año tras año en las pruebas diagnósticas realizadas en el ámbito europeo. A través del estudio bibliométrico de la producción científica se ha analizado las principales tendencias en gamificación, como práctica mediada por la tecnología en las aulas de las diferentes etapas educativas, a través de 137 documentos alojados en la base de datos Scopus y publicados en la última década. En los resultados se revela que el número de documentos se ha incrementado notablemente en los últimos años;…
To Gamify or Not to Gamify? : Gamification in Exercise Applications and Its Role in Impacting Exercise Motivation
2016
Gamification and different exercise applications have become increasingly popular in recent years. The common purpose of gamification is to enhance one’s motivation and engagement to certain activities. Gamification has been commonly understood as the use of game elements in non-game context. In this paper, we propose a divide between the process and the experience of gamification. This paper is the first to propose such division and the results demonstrate its necessity. Gamification exists also in many exercise applications. The purpose of this study is to explore how the use of an exercise application affects users’ exercise motivation and behaviour by concentrating especially on the rol…
