Desirable properties of performance indicators for assessing interactive evolutionary multiobjective optimization methods

2022

Interactive methods support decision makers in finding the most preferred solution in multiobjective optimization problems. They iteratively incorporate the decision maker's preference information to find the best balance among conflicting objectives. Several interactive methods have been developed in the literature. However, choosing the most suitable interactive method for a given problem can prove challenging and appropriate indicators are needed to compare interactive methods. Some indicators exist for a priori methods, where preferences are provided at the beginning of the solution process. We present some numerical experiments that illustrate why these indicators are not suitable for …

Improved Radio-Cesium Detection Using Quantitative Real-Time Autoradiography

2023

Cesium-134 and -137 are prevalent, long-lived, radio-toxic contaminants released into the environment during nuclear accidents. Large quantities of insoluble, respirable Cs-bearing microparticles (CsMPs) were released into the environment during the Fukushima Daiichi nuclear accident. Monitoring for CsMPs in environmental samples is essential to understand the impact of nuclear accidents. The current detection method used to screen for CsMPs (phosphor screen autoradiography) is slow and inefficient. We propose an improved method: real-time autoradiography that uses parallel ionization multiplier gaseous detectors. This technique permits spatially resolved measurement of radioactivity while …

Biopsychosocial Profiles of Patients With Cardiac Disease in Remote Rehabilitation Processes : Mixed Methods Grounded Theory Approach

2021

Background: Digital development has caused rehabilitation services and rehabilitees to become increasingly interested in using technology as a part of rehabilitation. This study was based on a previously published study that categorized 4 groups of patients with cardiac disease based on different experiences and attitudes toward technology (e-usage groups): feeling outsider, being uninterested, reflecting benefit, and enthusiastic using. Objective: This study identifies differences in the biopsychosocial profiles of patients with cardiac disease in e-usage groups and deepen the understanding of these profiles in cardiac rehabilitation. Methods: Focus group interviews and measurements were c…

Integrative Strategies in Mixed Methods Research

2020

Despite the critical role of integration as a methodological concept in mixed methods studies, researchers lack a theory for integrating. In this article, we introduce the concept of integrative strategy by analyzing three mixed methods rehabilitation-related studies. These studies represented an analytical strategy based on a multiperspective stakeholder approach, a theory-bound analytical strategy, and a theory-oriented synthesizing strategy. We define integrative strategy as a process in which the system of relations within the study is explicated and justified in accordance with the research purpose and phenomenon. This article contributes to mixed methods research by providing a novel…

Research Perspectives: Reconsidering the Role of Research Method Guidelines for Interpretive, Mixed Methods, and Design Science Research

2021

Information systems (IS) scholars have proposed guidelines for interpretive, mixed methods, and design science research in IS. Because many of these guidelines have also been suggested for evaluating what good or rigorous research is, they may be used as a checklist in the review process. In this paper, we raise the question: To what extent do research guidelines for interpretive, mixed methods, and design science research offer evidence that they can be used to evaluate the quality of research. We argue that scholars can use these guidelines to evaluate what good research is if there is compelling evidence that they lead to certain good research outcomes. We use three well-known sets of gu…

The division of domestic work among dual-career and other dual-earner couples in Finland

2015

This study compares the division of domestic work among dual-career and other dual-earner couples. We examine whether gender attitudes, relative resources and working time explain the differences between dual-career and other dual-earner couples. We define dual-career couples as those in which both spouses are professionals and/or managers. The division of housework is important for these couples because of the intense pressures of work. We hypothesise that domestic work is more equally shared among dual-career couples than among other dual-earner couples. The quantitative analyses are based on the Finnish data from the 2010 European Social Survey (N = 493). The qualitative data consist of …

A Bayesian Mixed-Methods Analysis of Basic Psychological Needs Satisfaction through Outdoor Learning and Its Influence on Motivational Behavior in Sc…

2017

Research has shown that outdoor educational interventions can lead to students' increased self-regulated motivational behavior. In this study, we searched into the satisfaction of basic psychological needs (BPN), i.e., autonomy support, the learners' experience of competence, and relatedness, both within the peer group and with their teachers, through outdoor learning. From 2014 to 2016, n = 281 students attended “research weeks” at a Student Science Lab in the Alpine National Park Berchtesgaden (Germany). The program is a curriculum-based one-week residential course, centered on a 2-day research expedition. Both before and after the course, students completed a composite questionnaire addr…

A new perspective on adolescent athletes’ transition into upper secondary school : A longitudinal mixed methods study protocol

2016

The challenge of combining elite sport and education into a dual career pathway remains to be a source of concern for many high-performance athletes. Previous research findings suggest that committed participation in both domains is highly demanding and success in one pursuit often comes at the expense of the other. There are emergent studies, however, that argue for the beneficial and complementary nature of dual career pathways. Consequently, we emphasize the importance of understanding the processes underlying differences in the development of athletes’ life trajectories. This article presents a study protocol to explore new methodological and analytical approaches that may extend curren…

L'analisi del focus group: testi, contesti e reti d'interazione in una prospettiva dinamica

International students' language use and attitudes towards English and Finnish

2014

Vaihto-opiskelu on kasvattanut suosiotaan sekä maailmanlaajuisesti että Suomessa erityisesti korkea-asteen opiskelijoiden keskuudessa. Suomi kohdemaana on hyvä esimerkki siitä, ettei nykyään pääsyy ulkomailla opiskeluun ole välttämättä kohdemaan kielen oppiminen, sillä maahan tullaan yleensä ilman paikallisten kielten osaamista ja opinnot suoritetaan englanniksi. Tämän tutkielman tarkoituksena oli kuvata, miten kansainväliset vaihto- ja tutkinto-opiskelijat käyttävät englantia, suomea ja muita osaamiaan kieliä Suomessa oleskelunsa aikana. Tarkemmin ottaen pyrittiin selvittämään, missä konteksteissa, mitä varten, keiden kanssa, kuinka usein ja kuinka onnistuneesti kansainväliset opiskelijat …
