Dataa näkyvissä: Läpinäkyvyys algoritmien ja datan journalistisessa hyödyntämisessä
2021
Läpinäkyvyyden käsite on noussut keskeiseksi viestinnän, median ja politiikan tutkimuksessa sekä viestinnän ja politiikan käytäntöjen eettisessä arvioinnissa. Läpinäkyvyyttä on esitetty keinoksi ylläpitää ja kasvattaa luottamusta journalistista työtä ja sen tuotteita kohtaan interaktiivisessa media- ja viestintäympäristössä. Tiedontuotannon ja päätöksenteon perustuessa yhä enemmän dataan ja sen prosessointiin läpinäkyvyys on noussut keskeiseksi käsitteeksi myös algoritmisen päätöksenteon kohdalla. Tässä artikkelissa tarkastelemme läpinäkyvyyden roolia dataa ja algoritmeja sekä journalismia koskevassa keskustelussa ja esitämme mahdollisuuksia dataan ja algoritmeihin tukeutuvan journalismin l…
A flexible and reconfigurable 5G networking architecture based on context and content information
2017
The need for massive content delivery is a consolidated trend in mobile communications, and will even increase for next years. Moreover, while 4G maturity and evolution is driven by video contents, next generation (5G) networks will be dominated by heterogeneous data and additional massive diffusion of Internet of Things (IoT). The current network architecture is not sufficient to cope with such traffic, which is heterogeneous in terms of latency and QoS requirements, and variable in space and time. This paper proposes architectural advances to endow the network with the necessary flexibility helping to adapt to these varying traffic needs by providing content and communication services whe…
Designing the 5G network infrastructure: a flexible and reconfigurable architecture based on context and content information
2018
5G networks will have to offer extremely high volumes of content, compared to those of today’s. Moreover, they will have to support heterogeneous traffics, including machine-to-machine, generated by a massive volume of Internet-of-Things devices. Traffic demands will be variable in time and space. In this work, we argue that all this can be achieved in a cost-effective way if the network is flexible and reconfigurable. We present the Flex5Gware network architecture, designed to meet the above requirements. Moreover, we discuss the links between flexibility and reconfigurability, on the one side, and context awareness and content awareness, on the other; we show how two of the building…
Tactics of invisibility : How people in vulnerable positions make datafied everyday life livable
2022
Various data platforms force the individual into constant presence and visibility. However, the ways in which datafied environments relate to experienced vulnerabilities in our everyday lives remain unclear. Through diaries produced by and interviews with participants from three groups who occupy presumably vulnerable positions and who currently live in Finland, we explore the ways in which people challenge expectations and prior assumptions related to forced visibility. Using the concept of tactics developed by de Certeau, we aim to understand how individuals make everyday surveillance culture livable through what we call tactics of invisibility. Based on our analysis, we identify three k…
Expression of emotion through musical parameters in 3- and 5-year-olds
2019
While the use of musical parameters for emotional expression has been extensively studied, little is known about which specific musical parameters children at different ages are able to use for expressing specific emotions. We used a novel interface called Music Box that allows modification of musical parameters while music is being played in real time. Children (N = 37, 18 girls) at the age of 3 and 5 were asked to modify three parameters – tempo, loudness, and pitch – in expressing three emotions – happiness, sadness, and anger. We hypothesised that both 5-year-olds and 3-year-olds could use each of the parameters in differentiating between the emotions. Results showed that 3-year-olds we…

Filling the Gap in the Metallacrown Family: The 9‐MC‐3 Chromium Metallacrown
2021
Abstract In this work, we report on a long‐sought missing complex in the metallacrown family. We synthesized and characterized the novel chromium metallacrown (MC) complex {CrIII(μ 2‐piv)3[9‐MCCr(III)N(shi)‐3](morph)3}⋅MeOH (in which shi3−=salicyl hydroxamate, piv=pivalate, and morph=morpholine). The MC with a 9‐MC‐3 cavity of kinetically inert chromium(III) ions was synthesized by a solvothermal reaction. Magnetization measurements reveal a high spin ground state.
Reflections about the authentic document in "post mortem" fecundation
2018
[EN] The legislation on assisted reproduction contemplates the ¿post mortem¿ fecundation. Nevertheless, the document for the presentation of the assent raises some doubts in relation with the principle of party autonomy and the new technologies of the information and communication (ICTs). In the present work one thinks about these questions and one tries to contribute some solution of application in the Spanish legal system.
Las obras musicales en las radios universitarias
2018
The Spanish General Audiovisual Communication Law does not relate to Campus Radio Stations. In this context, Copyright Collection Societies do not cover them in their catalogues of general fees. For this reason, the holders of these radios are forced to negotiate them. Althoug the Intellectual Property Law and the Order ECD/2574/2015, of 2 December, contain obligations for Copyright Collection Societies, on this matter its enforcement are far from being achieved
Radio environment map estimation based on communication cost modeling for heterogeneous networks
2017
Los mapas del entorno radioeléctrico pueden ser una poderosa herramienta para lograr una asignación de recursos eficiente y consciente del contexto en las redes heterogéneas 5G. En este trabajo, consideramos una red heterogénea formada por una red celular tradicional y una red de sensores inalámbricos. El papel de la red de sensores inalámbricos es estimar el mapa del entorno radioeléctrico de la célula utilizando una técnica de interpolación geoestadística denominada Kriging. En un trabajo anterior se propuso un algoritmo de agrupación distribuida de sensores para reducir la complejidad de la estimación. En nuestra contribución, el proceso de formación de clústeres se modifica para incluir…
