HR1 Robot: An Assistant for Healthcare Applications
2022
According to the World Health Organization1,2 the percentage of healthcare dependent population, such as elderly and people with disabilities, among others, will increase over the next years. This trend will put a strain on the health and social systems of most countries. The adoption of robots could assist these health systems in responding to this increased demand, particularly in high intensity and repetitive tasks. In a previous work, we compared a Socially Assistive Robot (SAR) with a Virtual Agent (VA) during the execution of a rehabilitation task. The SAR consisted of a humanoid R1 robot, while the Virtual Agent represented its simulated counter-part. In both cases, the agents evalua…
Real Virtuality: A Code of Ethical ConductRecommendations for Good Scientific Practice and the Consumers of VR-Technology
2016
The goal of this article is to present a first list of ethical concerns that may arise from research and personal use of virtual reality (VR) and related technology, and to offer concrete recommendations for minimizing those risks. Many of the recommendations call for focused research initiatives. In the first part of the article, we discuss the relevant evidence from psychology that motivates our concerns. In Section “Plasticity in the Human Mind,” we cover some of the main results suggesting that one’s environment can influence one’s psychological states, as well as recent work on inducing illusions of embodiment. Then, in Section “Illusions of Embodiment and Their Lasting Effect,” we go …
Dabīgo un modificēto mālu sorbtīvās īpašības
2017
Dabīgo un modificēto mālu sorbtīvās īpašības. Batarāga A. Zinātniskā vadītāja Mg. ķīm. Karasa J. Bakalaura darbs. 54 lappuses, 15 attēli, 15 tabulas, 24 literatūras avoti, 1 pielikums. Latviešu valodā. Darbā ir noteikta katjonu apmaiņas kapacitāte (CEC- cation exchange capacity) četriem mālu paraugiem: izejas Saltišķu karjera māliem, bagātinātiem, atdzelžotiem karjera māliem un references materiālam SWy-2. Noteikšana veikta ar dažādām tehnikām- vara(II) etilēndiamīna un amonija acetāta noteikšanas metodēm. Ar vara(II) etilēndiamīna metodi noteikšanā ir izmantotas divas pieejas: fotometriska un titrimetriska detektēšana. Amonija acetāta metodes gadījumā CEC noteikšanai ir izmantota jonometri…
The Valencia Eustress-Distress Appraisal Scale (VEDAS): Validation of the Italian Version
2018
© 2018 by the authors. The aim of this study is to validate the Italian version of the Valencia Eustress-Distress Appraisal Scale (VEDAS). Two hundred and thirty-two Italian workers were involved in the study. Dimensionality, reliability, and concurrent validity were analyzed. Confirmatory factor analysis supported a four-dimensional structure. In addition, the Italian version of the scale showed good internal consistency and validity. The results indicate that the Italian version of the VEDAS is a valid instrument for measuring eustress and distress appraisal in the Italian context. ispartof: SUSTAINABILITY vol:10 issue:11 status: published
Saules paneļu efektivitāte Latvijas klimatā
2019
Darba mērķis ir noteikt optimālo saules paneļu izvietojuma veidu Latvijas klimatiskajos apstākļos. Pētot divu veidu saules paneļus, kas novietoti piecās dažādās telpiskajās orientācijās Latvijas Universitātes Botāniskā dārza teritorijā, tiek noteikta solāro paneļu efektivitātes atkarība no šiem parametriem: Saules paneļu tips (JA vai LG); Telpiskā orientācija (R.13, A.13, D.13, D.40, D.90); Gada mēnesis (janvāris - aprīlis); Meteoroloģiskie apstākļi (saules apstarojums). Iegūtie monitoringa rezultāti tiek analizēti kontekstā ar saules izstarojuma intensitāti, paneļu potenciālās efektivitātes fizikālo novērtējumu un citu mērījumu rezultātiem. Rezultāti liecina, ka optimālie parametri ir LG p…
The Influence of School Climate and Family Climate among Adolescents Victims of Cyberbullying
2016
El ciberacoso es un fenómeno de creciente preocupación social que afecta cada vez más a niños y adolescentes de todos los paí- ses desarrollados. A diferencia de la considerable literatura que hay sobre las relaciones entre el acoso escolar y el contexto familiar y escolar, todavía hay pocos trabajos sobre la influencia de estos entornos sociales en el problema del ciberacoso. Mediante una metodología cuantitativa, el objetivo principal del presente estudio fue analizar la influencia del contexto escolar y familiar en víctimas de ciberacoso. La muestra estuvo formada por 1.062 adolescentes (51,5% chicos y 48,5% chicas), de edades comprendidas entre los 12 y los 18 años (M=14,5; DT=1,62). Se…
Map of the visibility and search engine positioning of the main Spanish media groups
2020
Este trabajo analiza la visibilidad y posicionamiento en buscadores de los sitios web de los principales grupos de comunicación españoles. Se compara su visibilidad web y su presencia en los resultados de búsqueda de Google a través de programas de análisis SEO y una metodología propia que se ha denominado Índice de Visibilidad Agregada. Se ha realizado un análisis comparativo de los grupos Atresmedia, COPE, Godó, Hearst Magazines, Henneo, Imagina Media Audiovisual, Intereconomía Corporación, Joly, Mediaset España Comunicación, Planeta, Prensa Ibérica, Prisa, Unidad Editorial, Vocento y Zeta. Se ha podido establecer que Unidad Editorial es el grupo con mayor tráfico web proveniente de búsqu…
Fitting the Stocking Rate with Pastoral Resources to Manage and Preserve Mediterranean Forestlands: A Case Study
2015
Pasture practices have affected Mediterranean forest ecosystems for millennia, and they are still quite widespread in mountainous areas. Nevertheless, in the last decades, the stability of forest ecosystems has been jeopardized due to the abandonment of traditional agro-pastoral practices, so that the gradual reduction of open areas due to progressive succession processes has caused a high increase of grazing pressure by livestock and wild ungulates feeding on forest areas. This paper aims at showing a methodological approach for evaluating the effect of applying measures in order to improve the grazing value of grasslands and ecotonal patches and lower the grazing impact on native woodland…
Valuing the unmarketable: an ecological approach to the externalities estimate in fishing activities
2013
In a rapidly changing world, sustainability, if it can be said to exist at all, is concept that has attained mythic status, often pursued and rarely reached. In order to improve our capability to cope with environmental problems, adopting an Ecosystem Approach has been suggested. One of the major challenges in the implementation of this new paradigm relates to control of externalities. The recognition and quantification of externalities is often cast as valuing the unmarketable, and there are several approaches that have been proposed. Here, we analyze the opportunity to “feed” the economic valuation with ecological concepts. From an ecological perspective, the energy required to sustain a …
Insulating Building Components Made from a Mixture of Waste and Vegetal Materials: Thermal Characterization of Nine New Products
2021
Nowadays, energy efficiency and sustainability are the fulcra of building policies. These policies promote the use of new technologies and materials that can reduce the primary energy involved and the environmental costs of construction, guarantying at the same time a high level of comfort for the building’s occupants. Synergy between previous construction techniques and the use of new materials should be pursued by employing materials with a low environmental impact and optimal thermal insulation properties. Within this framework, new materials derived from the agriculture sector, and waste or recycling products from the industrial/agricultural sectors have been studied. The aim of this pa…
