Combining PCA and multiset CCA for dimension reduction when group ICA is applied to decompose naturalistic fMRI data
2015
An extension of group independent component analysis (GICA) is introduced, where multi-set canonical correlation analysis (MCCA) is combined with principal component analysis (PCA) for three-stage dimension reduction. The method is applied on naturalistic functional MRI (fMRI) images acquired during task-free continuous music listening experiment, and the results are compared with the outcome of the conventional GICA. The extended GICA resulted slightly faster ICA convergence and, more interestingly, extracted more stimulus-related components than its conventional counterpart. Therefore, we think the extension is beneficial enhancement for GICA, especially when applied to challenging fMRI d…
Making group processes explicit to student
2014
This article considers student learning about group work in the context of project courses where student groups work under realistic expectations. Based on the literature, justice is explicated as a group work concept and regarded as a professional skill that can be practiced. Preliminary student feedback on teaching through continuous discussions on justice are presented together with teacher experiences.
Higher-order Nonnegative CANDECOMP/PARAFAC Tensor Decomposition Using Proximal Algorithm
2019
Tensor decomposition is a powerful tool for analyzing multiway data. Nowadays, with the fast development of multisensor technology, more and more data appear in higherorder (order > 4) and nonnegative form. However, the decomposition of higher-order nonnegative tensor suffers from poor convergence and low speed. In this study, we propose a new nonnegative CANDECOM/PARAFAC (NCP) model using proximal algorithm. The block principal pivoting method in alternating nonnegative least squares (ANLS) framework is employed to minimize the objective function. Our method can guarantee the convergence and accelerate the computation. The results of experiments on both synthetic and real data demonstrate …
Bilevel heat exchanger network synthesis with an interactive multi-objective optimization method
2012
Abstract Heat exchanger network synthesis (HENS) has been an active research area for more than 40 years because well-designed heat exchanger networks enable heat recovery in process industries in an energy- and cost-efficient manner. Due to ever increasing global competition and need to decrease the harmful effects done on the environment, there still is a continuous need to improve the heat exchanger networks and their synthesizing methods. In this work we present a HENS method that combines an interactive multi-objective optimization method with a simultaneous bilevel HENS method, where the bilevel part of the method is based on grouping of process streams and building aggregate streams …
Foreign captains in elite hockey markets: mediatized discourses of professionalization between routes and roots
2018
The commercial internationalization of professional ice hockey is shaped by tensions of (re)routing and (up)rooting since it involves (i) crossing geographic, ethnic, and linguistic boundaries to c...
The relationship between context, structure, and processes with outcomes of 6 regional diabetes networks in Europe
2018
BackgroundWhile health service provisioning for the chronic condition Type 2 Diabetes (T2D) often involves a network of organisations and professionals, most evidence on the relationships between the structures and processes of service provisioning and the outcomes considers single organisations or solo practitioners. Extending Donabedian's Structure-Process-Outcome (SPO) model, we investigate how differences in quality of life, effective coverage of diabetes, and service satisfaction are associated with differences in the structures, processes, and context of T2D services in six regions in Finland, Germany, Greece, Netherlands, Spain, and UK.MethodsData collection consisted of: a) systemat…
Value-added bioproducts or renewable energy derived from lignin? : comparative regional economic and environmental impact assessment : case Metsä Gro…
2016
Metsä Group’s next-generation bioproduct mill in Äänekoski will be operational within Q3/2017 and it will have significant regional economic impact on Central Finland. The mill will operate applying principles of circular economy, and thus utilize all possible side streams from pulp production. Lignin is one of the side streams that has huge potential to be refined, as sustainable products and by creating new value added. Conventionally, lignin is combusted with black liquor to generate energy in pulp mills. This thesis compares this conventional situation to refining lignin into biocomposite products made from 100% renewable resources with regard to regional economic and environmental impa…
Positions constructed for a female therapist in male batterers' treatment groups
2010
The aim of this study was to examine how male batterers regard to a female therapist in their group treatment. Of interest were the socially constructed positions for a female therapist. This study intends to examine what kind of positions the batterers construct for a female therapist in their speech and how the female therapist reacts to invitations to take up these positions. Attention was paid also to the male therapist’s positions in these situations. The topic was approached from a social constructionist and discourse analytic point of view and Grounded Theory was used as the method of analysing the data. The data consisted of five therapy groups for male batterers, each of which gath…
Ohjaajien toiminta elintapamuutosten tukemisessa tyypin 2 diabeteksen ehkäisyn ryhmäohjauksessa
2016
The purpose of the study was to describe the supervisors’ action in the support of changing one’s living habits in two weight management groups in the type 2 diabetes prevention program. The data consists of 17 video-recorded 90-minute “Small decision a day” weight management group counselling sessions of two groups with 10 and 20 participants in the years 2004-2005. The supervisors’ talk was analyzed with the deductive analysis from five teaching perspectives including theirs beliefs, intentions and actions. The transtheoretical change model and the participants’ talk were analyzed with the inductive analysis. Quantitative methods were used to give more information about the counselling se…
Preparing physical and health education pre-service teachers to support students’ physical activity and wellbeing during the school day
2017
Increasingly, physical education teachers are expected to become the cog in an ever-expanding physical activity (PA) promotion wheel. This requires such teachers to be equipped with new knowledge a...
