Justification of point electrode models in electrical impedance tomography
2011
The most accurate model for real-life electrical impedance tomography is the complete electrode model, which takes into account electrode shapes and (usually unknown) contact impedances at electrode-object interfaces. When the electrodes are small, however, it is tempting to formally replace them by point sources. This simplifies the model considerably and completely eliminates the effect of contact impedance. In this work we rigorously justify such a point electrode model for the important case of having difference measurements ("relative data") as data for the reconstruction problem. We do this by deriving the asymptotic limit of the complete model for vanishing electrode size. This is s…
Career Transitions of eSports Athletes : A Proposal for a Research Framework
2017
eSports has boomed, the number of eSport athletes has grown rapidly, and many teenagers aspire to a have career in eSports. However, eSports athletes' careers involve many problems, such as career-entry difficulties, straining life habits, burnout, premature retirement, and post-career dilemmas. Despite a growing research interest in eSports, a void of knowledge exists regarding eSports athletes' career aspects. To address the gap in research, this paper aims to take an initial step by proposing a framework for eSports athletes' career transitions. The framework combines two approaches from sport psychology and sport literature. The framework can help eSports athletes, coaches, and other st…
Efficient Time Integration of Maxwell's Equations with Generalized Finite Differences
2015
We consider the computationally efficient time integration of Maxwell’s equations using discrete exterior calculus (DEC) as the computational framework. With the theory of DEC, we associate the degrees of freedom of the electric and magnetic fields with primal and dual mesh structures, respectively. We concentrate on mesh constructions that imitate the geometry of the close packing in crystal lattices that is typical of elemental metals and intermetallic compounds. This class of computational grids has not been used previously in electromagnetics. For the simulation of wave propagation driven by time-harmonic source terms, we provide an optimized Hodge operator and a novel time discretizati…
Short-Time Non-work-related Computing and Creative Performance
2014
It has been argued that non-work-related computing (NWRC) takes time away from work and, hence, decreases work productivity. On the other hand, it has also been claimed that short-time non-work-related computing (STNWRC) (a maximum of 15 minutes), has a positive impact on work productivity, including relief from boredom, higher creativity, and the underlying recovery mechanisms. To examine the impact of STNWRC on creative performance, we draw on Fredrickson's broaden-and-build theory, the concept of recovery with mental well-being and low cognitive effort. A 2 × 2 factorial experiment with 40 subjects was conducted. The results indicate that STNWRC has a positive effect on creative performa…
Looking for Peace of Mind? Manage your (Technical) Debt : An Exploratory Field Study
2017
Background: In the last two decades Technical Debt (TD) has received a considerable amount of attention from software engineering research and practice. Recently, a small group of studies suggests that, in addition to its technical and economic consequences, TD can affect developers’ psychological states and morale. However, until now there has been a lack of empirical research clarifying such influences. Aims: In this study, we aim at taking the first step in filling this gap by investigating the potential impacts of TD and its management on developers’ morale. Method: Drawing from previous literature on morale, we decided to explore the influence of TD and its management on three dimensio…
Bisexual desires for more than one gender as a challenge to normative relationship ideals
2018
Normative western understandings of intimate relationships continue to draw upon the discourses of romantic love and the ideal of finding ‘the one’ who meets all our romantic and sexual needs. As desire is not sexually or emotionally exclusive, even people in normative relationships have to make sense of desires beyond the monogamous ideal. Bisexual people engage in these negotiations from a challenging cultural position. As a desire for more than one gender, bisexuality is persistently culturally associated with wavering desire, promiscuity and multiple partners. In light of these cultural conditions, I explore how Finnish bisexual women – and their (ex-)partners of various genders who do …
Changing people’s attitudes and beliefs toward driving through floodwaters : Evaluation of a video infographic
2018
Abstract Despite awareness of campaigns such as ‘Turn Around, Don’t Drown’ and the Australian state of Queensland’s ‘If It’s Flooded, Forget It’, people continue to drive through floodwaters, causing loss of life, risk to rescuers, and damage to vehicles. The aim of this study was to develop a video infographic that highlights the dangers of driving through floodwaters and provide safety tips to reduce the risk, and to evaluate its effectiveness in changing the beliefs and intentions of Australian adults toward this risky driving behaviour. This study adopted an online three-wave non-controlled pretest–posttest design. Australian licensed drivers (N = 201, male = 41, female = 160; Mage = 34…
Negotiating female judoka identities in Greece : A Foucauldian discourse analysis
2015
Abstract Objectives The objectives of this paper are to trace the discourses through which female Greek judokas articulate their sporting experiences and to explore how they construct their identities through the negotiation of sociocultural beliefs and gender stereotypes. Design This article is based on interview data from a larger ethnographic research with women judo athletes, grounded in a cultural praxis framework. Method Ten semi-structured interviews were conducted during fieldwork in Greece. Interview data were analyzed drawing on a Foucauldian approach to discourse analysis. Results We identified four concepts—biology, gender, femininity, and judo/sport—that were central to unearth…
Limittäiskielisyys osana kuvataiteen prosesseja
2023
Tässä artikkelissa käsittelen kahdeksan Berliinissä asuneen suomalaislähtöisen kuvataiteilijan käsityksiä kielten merkityksestä identiteettiinsä ja taiteeseensa. Vastaan kolmeen tutkimuskysymykseen; ensinnäkin siihen, miten eri kielten käyttö on vaikuttanut taiteilijoiden identiteettiin, toisekseen siihen, miten he käyttävät kieliä visuaalisessa taiteessaan ja lopuksi siihen, mikä rooli kielellä, monikielisyydellä/limittäiskieleilyllä on heidän taiteessaan. Kesällä 2019 ja talvella 2021 kerätty aineisto koostuu kuvataiteilijoiden haastatteluista, ottamistani valokuvista taiteilijoiden työhuoneilta ja heidän töistään sekä heidän julkaisemistaan kirjoista ja nettisivuista. Tässä artikkelissa …
"Writing to Learn or Learning to Write". A Critical Review of "English as a Foreign Language" (EFL) Teaching Practices in Writing in Saudi Universiti…
2020
Developing proficiency in English writing has always been a challenge for L2 learners in general and Saudi learners in particular. Despite the widespread presence of English departments as a result of the sharp rise of Saudi universities in the previous decade, the numbers of outcomes or achievements in terms of skills are very discouraging. This paper aims to study this issue closely by investigating the most crucial elements that are likely to explain this weakness by reviewing the related empirical and theoretical studies in the Saudi context. This paper also aims to present to researchers a quick reference as to how English writing skills have evolved in Saudi Arabia in the recent past,…
