Can we automate expert-based journal rankings? Analysis of the Finnish publication indicator
2020
The publication indicator of the Finnish research funding system is based on a manual ranking of scholarly publication channels. These ranks, which represent the evaluated quality of the channels, are continuously kept up to date and thoroughly reevaluated every four years by groups of nominated scholars belonging to different disciplinary panels. This expert-based decision-making process is informed by available citation-based metrics and other relevant metadata characterizing the publication channels. The purpose of this paper is to introduce various approaches that can explain the basis and evolution of the quality of publication channels, i.e., ranks. This is important for the academic …
Social media users in search of ‘facts’: the Trade Union House fire case
2021
What factors influence users to believe the stories they find in social media, and what role do emotions play for users in concluding that a particular fact is ‘true’? This article examines one aspect of emotionalized communication in social networks in an information war context, namely, how social network users make decisions about the reliability of the information they receive. We employ a qualitative study of a single case – a discussion among Russian-speaking Livejournal.com and Facebook.com users of a tragic incident in Ukraine – the deadly fire that took place in the Odessa Trade Union House on 2 May, 2014. The relevancy of this case consists in how, for all its uniqueness as a trag…
Information, Communications and Media Technologies for Sustainability: Constructing Data-Driven Policy Narratives
2021
This paper introduces the idea of data-driven narratives to examine how the use of information, communications, and media technologies (ICMTs) impacts the sustainable growth of economies. While ICMTs have regularly been advocated as a policy tool for growth and development, there is a research gap in empirical studies validating how such policies may be effective. This analysis is based on historical panel data from 39 economies across the developed North (19) and developing South (20). The industry-standard Cross-Industry Standard Process for Data Mining (CRISP-DM) methodology was applied to construct narratives that weave extant theories with empirical data. The art of developing data-dri…
A Study on the Assessment of Introductory Computational Thinking via Scratch Programming in Primary Schools
2018
Computational thinking (CT), a transversal intellectual foundation integral to computer science, is making its way into compulsory comprehensive education worldwide. Students are expected to attain skills and knowledge in such interdisciplinary CT principles as Algorithmic thinking, Data representation, and Debugging. Problem-solving by designing and manipulating interactive media with Scratch, a graphical programming tool, is popular especially at the primary school level. However, there has been confusion regarding how introductory CT can be operationalized for educational practice. Teachers and students need research-based knowledge for setting appropriate learning goals in addition to i…
Single chords convey distinct emotional qualities to both naïve and expert listeners.
2014
Previous research on music and emotions has been able to pinpoint many structural features conveying emotions. Empirical research on vertical harmony’s emotional qualities, however, has been rare. The main studies in harmony and emotions usually concern the horizontal aspects of harmony, ignoring emotional qualities of chords as such. An empirical experiment was conducted where participants ( N = 269) evaluated pre-chosen chords on a 9-item scale of given emotional dimensions. 14 different chords (major, minor, diminished, augmented triads and dominant, major and minor seventh chords with inversions) were played with two distinct timbres (piano and strings). The results suggest significant…

Estimation of the Time-Variant Velocity of a Single Walking Person in Two-Dimensional Non-Stationary Indoor Environments Using Radio-Frequency Techni…
2020
Accurate estimation of the time-variant (TV) velocity of moving persons/objects in indoor spaces is of crucial importance for numerous wireless indoor applications. This article introduces a novel iterative procedure to estimate the TV velocity, i.e., TV speed and TV angle-of-motion (AOM), of a single moving person in 2D indoor environments by using radio-frequency (RF) techniques. The indoor area is equipped with a distributed 2 × 2 multiple-input multiple-output (MIMO) system. The proposed method is divided into two parts. In the first part, we estimate the path gains and the instantaneous Doppler frequencies by fitting the exact spectrograms of the complex channel gains of a 2D no…
La imprenta en México: cuestiones terminológicas y tipología de los primeros impresos americanos
2020
espanolLa cultura impresa mexicana tiene su origen en los albores del siglo XVI con la instalacion de la primera prensa tipografica en el continente y la fabricacion de las primeras ediciones impresas en el continente. Esta primitiva produccion, y cada uno de los ejemplares que la integraba, fechados entre 1539 y 1634, recibieron el nombre de incunables americanos a semejanza de los primeros libros impresos en Europa entre la creacion de la imprenta y el 1 de enero de 1501. Sin embargo, poco tenian que ver los iniciales americanos con los primeros textos impresos en Europa hacia mas de cincuenta anos, por lo que la utilizacion del termino incunable resulto desde un primer momento confusa. E…
Hölder regularity for stochastic processes with bounded and measurable increments
2022
We obtain an asymptotic Hölder estimate for expectations of a quite general class of discrete stochastic processes. Such expectations can also be described as solutions to a dynamic programming principle or as solutions to discretized PDEs. The result, which is also generalized to functions satisfying Pucci-type inequalities for discrete extremal operators, is a counterpart to the Krylov-Safonov regularity result in PDEs. However, the discrete step size $\varepsilon$ has some crucial effects compared to the PDE setting. The proof combines analytic and probabilistic arguments.
Neurocognitive Predictors of Response to Intervention With GraphoGame Rime
2021
This study explores the neurocognitive predictors of response to intervention with GraphoGame Rime, an adaptive software game designed to aid the learning of English phonics. A cohort of 398 children (aged 6 – 7 years) who had participated in a recent Randomized Controlled Trial (RCT) of GraphoGame Rime in the United Kingdom were studied. Half were randomly assigned to play GraphoGame Rime (GG Rime) and the other half were assigned to Business As Usual (BAU). A series of pretests were given prior to the intervention to all participants, designed to measure phonological awareness skills, executive function (EF) skills and the ability to synchronise finger tapping to a rhythmic beat. Finger t…
