Ihmisen visuaalinen hahmottamiskyky ja fysiologisen datan esittäminen

2015

Tutkimuksen tarkoituksena oli saada ymmärrys siitä, miten ihminen ymmär-tää visuaalista dataa ja miten fysiologista dataa kannattaa visualisoida. Tutki-muksen teoriaosuudessa syvennyttiin ihmisen visuaaliseen havaitsemis- ja hahmottamiskykyyn, tiedon visualisointiin ja visuaaliseen käytettävyyteen. Edellä mainittujen pohjalta luotiin suunnitteluperiaatteet fysiologisen (graafi-sen) datan esittämiselle. Tutkimuksen toimintaosuudessa tarkastelun kohtee-na oli Firstbeat Technologies Oy:n Hyvinvointianalyysin palautesivu, josta opinnäytteentekijä rakensi vaihtoehtoisen version perustuen suunnitteluperi-aatteisiin. Tutkimuksen taustalla oli ajatus Hyvinvointianalyysin tulossivujen selkiyttämises…

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…

Sense experience and differentiation : Husserl on bodily awareness

2023

This article outlines the basic ingredients of Husserl’s theory of bodily awareness. It first analyses the concepts of hyletic and kinesthetic sensibility, and illustrates the interwovenness and equiprimordiality of Me and not-Me in Husserl’s account. Second, it shows how the concept of the lived body emerges from this complex sensible foundation. Thirdly, it argues that, as the area of intersection between the Me and the not-Me, bodily awareness is the initial locus of differentiation between Me and not-Me: an area where the experiential distinction between the Me and the not-Me is constantly negotiated. peerReviewed

Qualitative analysis of housing demand using Google trends data

2019

Big data analytics often refer to the breakdown of huge amounts of data into a more readable and useful format. This study utilises Google Trends big data as a proxy for an analysis of housing demand. We employ a qualitative method (fuzzy set/Qualitative Comparative Analysis, fsQCA), instead of a quantitative method, for our estimate and forecast. The empirical results show that fsQCA successfully forecasts seasonal time series, even though the dataset is small in size. Our findings fill the gap in the qualitative and time series forecasting literature, and the forecasting procedure herein also offers a good standard for industry.

Efficient remote authentication

2013

In 2003, Kennel and Jamieson described a method of remote machine authentication. By authentication, the authors meant that the remote machine is non-virtual, and the operating system on the remote machine is not malicious. The described method does not consider the variety of versions of each operating system. The description completely ignores the existence of modules that can be plugged into the operating system. The authors of this paper adapt the method described by Kennel and Jamieson to the real world so that itcan be applied without prior knowledge of theoperating system or the modules on the remote machine. peerReviewed

On research work in information systems: Guidelines, recommendations and examples

2021

The most positive aspect of science is that the participants (researchers, reviewers and editors) control and evaluate their work themselves. Therefore they must be supported in one way or another. Fortunately, guidelines have been developed for different methodologies. However, today the guidelines are not very applicable. The first two sets of guidelines published (both positivist studies) had unusual problems. In this work, we analyze and improve the guidelines generally. Previously, selecting a methodology was the task of every researcher. It now seems that every researcher must also conduct a literature review and write a report. We consider methodology, literature review and writing "…

Dynamic Usage-based Principles in the Development of L2 Finnish Evaluative Constructions

2021

Abstract This study investigates the formal verbalizations of evaluation used by four beginning L2 learners of Finnish from a dynamic usage-based perspective. Longitudinal data collected weekly were used to investigate what kind of constructions learners use to express evaluation and how these interact and develop over time. The results show that when a new construction is acquired in the L2, another related construction might regress. The results also point to increased variability in the construction during a phase of rapid development and reduced variability in the phases of regression or slower progress. These findings add to our understanding of a developing L2 as a system in which cha…

TallVocabL2Fi : A Tall Dataset of 15 Finnish L2 Learners’ Vocabulary

2022

Previous work concerning measurement of second language learners has tended to focus on the knowledge of small numbers of words, often geared towards measuring vocabulary size. This paper presents a “tall” dataset containing information about a few learners’ knowledge of many words, suitable for evaluating Vocabulary Inventory Prediction (VIP) techniques, including those based on Computerised Adaptive Testing (CAT). In comparison to previous comparable datasets, the learners are from varied backgrounds, so as to reduce the risk of overfitting when used for machine learning based VIP. The dataset contains both a self-rating test and a translation test, used to derive a measure of reliability…
