Parasite avoidance behaviours in aquatic environments
2018
Parasites, including macroparasites, protists, fungi, bacteria and viruses, can impose a heavy burden upon host animals. However, hosts are not without defences. One aspect of host defence, behavioural avoidance, has been studied in the terrestrial realm for over 50 years, but was first reported from the aquatic environment approximately 20 years ago. Evidence has mounted on the importance of parasite avoidance behaviours and it is increasingly apparent that there are core similarities in the function and benefit of this defence mechanism between terrestrial and aquatic systems. However, there are also stark differences driven by the unique biotic and abiotic characteristics of terrestrial …

When modelling mobile radio channels with moving scatterers, it is generally assumed that the angles of departure (AODs), angles of arrival (AOAs), and the speed of the scatterers are time-invariant. However, this assumption is violated as the AODs and AOAs vary with the positions of t…
Design and Implementation of a Tool for Analysing Student Products When They Solve Fermi Problems
2017
In this chapter, we present a tool for analysing the work of secondary-level students from two different schools when they solve a type of Fermi problem. The tool is based on the characterisation of the concepts, procedures and language used to construct the models. Our results show that the proposed tool is useful to describe the models and to distinguish different aspects between the models produced by students without any previous modelling experience and those obtained by students who were already acquainted with working on modelling activities.
A new approach for estimating a nonlinear growth component in multilevel modeling
2011
This study presents a new approach to estimation of a nonlinear growth curve component with fixed and random effects in multilevel modeling. This approach can be used to estimate change in longitudinal data, such as day-of-the-week fluctuation. The motivation of the new approach is to avoid spurious estimates in a random coefficient regression model due to the synchronized periodical effect (e.g., day-of-the-week fluctuation) appearing both in independent and dependent variables. First, the new approach is introduced. Second, a Monte Carlo simulation study is carried out to examine the functioning of the proposed new approach in the case of small sample sizes. Third, the use of the approac…
How Students Get Going : Triggers for Students’ Learning in Project-Based Education
2018
Repeatedly documented positive student responses to project-based learning during its decades-long tradition in CS attest to the effectiveness of learning by doing. Support for reflective learning nevertheless continues to be a topic worth studying because the intensity of project work together with a high technical orientation among CS students often complicate reflective practice. A critical incident-inspired assignment was added to a project-based course to support reflective practice in spring 2017. In a previous study, the authors analyzed how students approached the assignment and whether they found it supportive for learning. The present study content-analyses the situations that tri…
Learnings from the Finnish Game Industry
2016
The motivation behind our research was the rapid growth and business wins of world-class Finnish game companies, like Supercell, as well as the success of other game companies in Finland. In particular, Supercell's growth is something that has not been heard of before and this raised the interest to research what game companies have been doing right. Supercell is not the only Finnish success. Rovio is also well known and has the roots for success from few years before. There are also other game companies in Finland that have succeeded and this motivated us to investigate what is happening behind the game industry and what could be learned from there that could be applied to other software i…
Open-ended projects opened up — aspects of openness
2017
Abstract—One of the most important areas of competence for professional engineers is the ability to function well in project work, in particular they need to be able to efficiently solve open-ended problems in different collaborative settings. The development of this ability is however not prominent in engineering education despite numerous authors suggesting openended problems as a pedagogical tool to promote development of collaborative problem solving competence by including elements of group or project work in courses. In our own long experience of using open-ended problems in collaborative student projects, we have identified a lack of systematic progression in learning outcomes and sk…
Learning styles module as a part of a virtual campus
2016
For several years now, learning style mapping has been carried out for our students of the master's degree education in information technology. To better utilize learning styles in practice, a learning style module was integrated into the multimedia platform used in the education. The learning style module serves both the student and the educator. The goal was to create an application which, in the long run, would diversify the learning environment and make learning more efficient. This study describes the functioning and integration of the learning style application. The deployment of the application is monitored by collecting statistics of its use and feedback of its usability and usefuln…
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…
Educational Technology Goes Mobile
2018
Recent decades have revealed that the digital educational technology that is expected to revolutionise schooling for generations to come, is fraught with challenges. One major challenge is that educational systems vastly vary between cultures and countries. The differences start from the conceptualisation of education and school. It is, therefore, quite inaccurate to handle education as a universal concept. In this article the authors evade generalisation by discussing the use of mobile technology in the schools of one single, relatively homogenous nation: Finland. The backbone of their analysis is the core national curriculum of basic education. The appropriateness of mobile technology in …
