Time-Frequency Characteristics of In-Home Radio Channels Influenced by Activities of the Home Occupant
2019
While aging is a serious global concern, in-home healthcare monitoring solutions are limited to context-aware systems and wearable sensors, which may easily be forgotten or ignored for privacy and comfort reasons. An emerging non-wearable fall detection approach is based on processing radio waves reflected off the body, who has no active interaction with the system. This paper reports on an indoor radio channel measurement campaign at 5.9 GHz, which has been conducted to study the impact of fall incidents and some daily life activities on the temporal and spectral properties of the indoor channel under both line-of-sight (LOS) and obstructed-LOS (OLOS) propagation conditions. The time-frequ…
Dialogicality in making sense of online collaborative interaction : a conceptual perspective
2021
In higher education, learning activities increasingly take place in online collaborative groups. In this conceptual paper, we explore online collaborative interaction from the perspective of dialogicality. We aim to reconceptualize the notion of “productive interaction” and the typical focus of its research by turning attention to the dialogic features of collaborative interaction, especially the notions of alterity, dialogic attitude, and dialogic orientation. In relation to this, we offer a contextual perspective on collaborative interaction. Relying on data from an online university course, we conceptually analyze specified components of dialogicality. This article illustrates and explor…
Oligophenyls with Multiple Disulfide Bridges as Higher Homologues of Dibenzo[c,e][1,2]dithiin: Synthesis and Application in Lithium-Ion Batteries.
2020
Abstract Higher homologues of dibenzo[c,e][1,2]dithiin were synthesized from oligophenyls bearing multiple methylthio groups. Single‐crystal X‐ray analyses revealed their nonplanar structures and helical enantiomers of higher meta‐congener 6. Such dibenzo[1,2]dithiin homologues are demonstrated to be applicable to lithium‐ion batteries as cathode, displaying a high capacity of 118 mAh g−1 at a current density of 50 mA g−1.
Information and communication technologies and teacher education in the new paradigms of higher education
2018
Abstract Media use in the teaching process occurs in several forms. Information and communication technologies can be used as work equipment and teaching aids, as well as tools or curriculum units, particularly in higher education. Technological changes and new information technologies, in addition to substantive knowledge of the material, require from teachers creativity, knowledge, and the skills of the didactic design of teaching using modern multimedia tools. In Croatia, there is a lack of research aimed at assessing the initial state of computer literacy within the higher education institutions. The aim of this study was to determine the level of knowledge and digital competence of (no…
Oppimisen teknologiat osana oppimisen esteitä kohtaavien peruskoululaisten elämää
2017
Tieto- ja viestintäteknologia on merkittävä osa jokapäiväistä elämäämme. Nämä teknologiat ovat löytäneet tiensä kouluihin myös Suomessa, ja erilaisia oppimisen teknologioita onkin otettu ahkerasti käyttöön ympäri maata. Teknologian integroiminen osaksi opetusta ei kuitenkaan aina suju täysin ongelmitta. Laitteiden käytössä saattaa ilmetä ongelmia, ja vaikka infrastruktuuri teknologian käytölle olisikin olemassa, ovat verkkoyhteydet paikoitellen epävakaita. Näiden ongelmien kanssa painivat sekä opettajat että oppilaat. Tämän tutkielman tarkoituksena on tutkia oppimisen teknologioiden vaikutuksia erityisesti oppimisen esteitä kohtaavien oppilaiden oppimiseen. Oppimisen esteitä, kuten erilaisi…
Value Co-Creation Opportunities: Managerial Transformation of Digitisation Risks into Success Factors
2018
This chapter examines the challenges and risks managers in the healthcare sector perceive in relation to the development and implementation of digitised services in a healthcare case organisation. Using data collected from managers, focus group interviews and observation method within the case organisation, the authors present an analysis that demonstrates that the risks and success factors that influence the development and implementation of digital healthcare services are related to (1) setting a clear digital strategy and implementation plan, (2) integration of digital services with the overall process and ICT, (3) committed resources and engagement of personnel, and (4) the organisation…

The global spread of the concept of cultural policy
2020
The article studies UNESCO's program that, from the late 1960s onward, aimed at spreading globally the concept of cultural policy. An essential part of the program, UNESCO invited member states from different regions of the world to prepare reports on national cultural policy. That was successful in spreading cultural policy as a concept and as a governmental structure. Except for only Australia, Canada and the United States, in which cultural policy is handled at a sub-state level, all countries that produced a national report have established a ministry of culture, typically synchronously with the report. The analysis suggests that UNESCO's success was due to two factors: the process of d…
Prepublicaciones: distribucion centralizada vs. descentralizada.
2000
Prepublications are accounts of research results that are distributed prior to formal publication in scientific journals. They are the form of scholarly communication that has taken more advantage of the advances in telecommunication and information technologies. Their electronic distribution has taken a different form within the disciplines. In this paper we compare the decentralized model of Economies with the centralized model of Physics.<br><br>Las Prepublicaciones, borradores de trabajos distribuídos antes de su publicacion formal en revistas, han sido el proceso de comunicación científica que más se ha beneficiado de los avances en telecomunicaciones. Su distribución elect…
