Soundscape design through evolutionary engines
2008
Abstract Two implementations of an Evolutionary Sound Synthesis method using the Interaural Time Difference (ITD) and psychoacoustic descriptors are presented here as a way to develop criteria for fitness evaluation. We also explore a relationship between adaptive sound evolution and three soundscape characteristics: keysounds, key-signals and sound-marks. Sonic Localization Field is defined using a sound attenuation factor and ITD azimuth angle, respectively (Ii, Li). These pairs are used to build Spatial Sound Genotypes (SSG) and they are extracted from a waveform population set. An explanation on how our model was initially written in MATLAB is followed by a recent Pure Data (Pd) impleme…
Multilingualism in (Foreign) Language Teaching and Learning
2019
I am an applied linguist who considers language learning to be a socially constructed practice. In fact, I would rather talk about applied language studies than applied linguistics, as I understand this area of inquiry to include any language-related research that bears a strong connection to societally significant phenomena. In that broad palette of research, my own work would be placed at the interface of the areas of language learning and teaching, on the one hand, and discourse studies and sociolinguistics, on the other. I have always worked with students who wish to be language teachers. Over the years, I have seen hundreds of students entering working life that is in constant turmoil.…
Do humans dream of prophetic robots?
2020
Social robotics is a technology that, as its definition varies, encompasses conceptually diverse fields materializing in innovations from simple chatbots to sophisticated androids talking about the peaceful coexistence of humans and robots. The advances in social robotics have led to promising applications in education, work, entertainment, and even religion. Yet a measure of fear and confusion about the capabilities of contemporary and future robots exists, with one of the reasons being the presentation of some contemporary robots as being more advanced than they really are.
Yhteisöllinen argumentointi sosionomikoulutuksessa avoimia ongelmia ratkottaessa
2017
The aim of this study was to develop teaching methods for practising argumentative problem-solving in a degree program of social services. The purpose was to acquire knowledge about multiple (face-to-face, online, and integrated) learning environments for studying argumentative problem-solving. In addition, the typical features of collaborative argumentation in student discussions were identified. Two teaching experiments were arranged in courses on drug and alcohol abuse. Both experiments required students to solve open-ended problems through role-play regarding a fictive girl’s use of alcohol. The idea of blended learning was applied in the first teaching experiment. Students (n = 29) wro…
Mini-drones swarms and their potential in conflict situations
2020
The Unmanned Aerial Vehicles (UAV) commonly known as drones are currently used in a wide range of operations such as border monitoring, aerial reconnaissance, traffic control and military interventions in armed conflicts. These aerial vehicles are expected to be reliable, automated and sometimes autonomous machines, albeit the human factor continues to play a crucial role in programming and control. At their genesis, drones were complex, large and reserved to an exclusive club of technologically advanced military powers. They tended to be used against technologically weak military targets. Developments in the price, size and sophistication of drones has now enabled almost anyone to purchase…
Cooperative sound design: a protocol analysis
2016
Formal protocol analysis and linkographic representations are well-established approaches in design cognition studies, in the visual domain. We introduce the method and tools in the auditory domain, by analysing a case of collaborative sound design. We show how they can provide relevant qualitative and quantitative information about the efficiency of the creative process.
Numerical methods for a nonlinear impact model: A comparative study with closed-form corrections
2011
A physically based impact model-already known and exploited in the field of sound synthesis-is studied using both analytical tools and numerical simulations. It is shown that the Hamiltonian of a physical system composed of a mass impacting on a wall can be expressed analytically as a function of the mass velocity during contact. Moreover, an efficient and accurate approximation for the mass outbound velocity is presented, which allows to estimate the Hamiltonian at the end of the contact. Analytical results are then compared to numerical simulations obtained by discretizing the system with several numerical methods. It is shown that, for some regions of the parameter space, the trajectorie…
Measuring the Task Induced Oscillatory Brain Activity Using Tensor Decomposition
2019
The characterization of dynamic electrophysiological brain activity, which form and dissolve in order to support ongoing cognitive function, is one of the most important goals in neuroscience. Here, we introduce a method with tensor decomposition for measuring the task-induced oscillations in the human brain using electroencephalography (EEG). The time frequency representation of source-reconstructed singletrail EEG data constructed a third-order tensor with three factors of time ∗ trails, frequency and source points. We then used a non-negative Canonical Polyadic decomposition (NCPD) to identify the temporal, spectral and spatial changes in electrophysiological brain activity. We validate …
Argument graph as a tool for promoting collaborative online reading
2013
This study explored how the construction of an argument graph promotes students' collaborative online reading compared to note-taking. Upper secondary school students (n = 76) worked in pairs. The pairs were asked to search for and read source material on the Web for a joint essay and either construct an argument graph or take notes during online reading. The data consist of transcription protocols of student pairs' discussions and joint essays. The study indicated that argument graphs may be useful tools when teachers want students to pay attention to the argumentative content of online sources and to consider relations between arguments. Additionally, with argument graphs, teachers can su…
Behind screens : challenges and opportunities of participatory online peace education in Finland
2022
This article discusses the challenges and opportunities of participatory online teaching and learning in higher education. It analyses an online peace education course taught during the Covid-19 pandemic in three Finnish universities between 2020–2021. The course explored fundamental mediation skills and practices of positive peace through participatory methods and applied drama. We show how the online setting affected students and teachers, by focusing on the challenges and opportunities for participatory pedagogy in an online environment. The course feedback from students (N = 23) was studied by content analysis and conjoined with the ethnographic observations of the authors. Our findings…
