LR-NIMBUS : an interactive algorithm for uncertain multiobjective optimization with lightly robust efficient solutions
2022
In this paper, we develop an interactive algorithm to support a decision maker to find a most preferred lightly robust efficient solution when solving uncertain multiobjective optimization problems. It extends the interactive NIMBUS method. The main idea underlying the designed algorithm, called LR-NIMBUS, is to ask the decision maker for a most acceptable (typical) scenario, find an efficient solution for this scenario satisfying the decision maker, and then apply the derived efficient solution to generate a lightly robust efficient solution. The preferences of the decision maker are incorporated through classifying the objective functions. A lightly robust efficient solution is generated …
A quantitative reverse Faber-Krahn inequality for the first Robin eigenvalue with negative boundary parameter
2021
The aim of this paper is to prove a quantitative form of a reverse Faber-Krahn type inequality for the first Robin Laplacian eigenvalueλβwith negative boundary parameter among convex sets of prescribed perimeter. In that framework, the ball is the only maximizer forλβand the distance from the optimal set is considered in terms of Hausdorff distance. The key point of our stategy is to prove a quantitative reverse Faber-Krahn inequality for the first eigenvalue of a Steklov-type problem related to the original Robin problem.
How Physical Education Teachers’ Interpersonal Behaviour is Related to Students’ Health-Related Quality of Life
2019
Grounded in self-determination theory (SDT), this cross-sectional study tested relations of students’ perceptions of autonomy-supportive and controlling behaviour from teachers in physical education with students’ health-related quality of life (HRQoL), and the potential role of students’ perceived need satisfaction and need frustration as a mediator of these relationships. School students (N = 1031) completed self-report measures of perceived autonomy support, perceived teachers’ controlling behaviour, students’ need satisfaction and need frustration, and HRQoL. Results indicated that students’ perceptions of autonomy support from teachers was positively associated with HRQoL through need …
Solvent directs the dimensionality of Cu-dicyanoimidazoles
2022
In this paper, we report one-pot reactions of the same reactants 4,5-dicyanoimidazole and CuI in different solvents. In pure MeCN, the reaction resulted in previously reported MOF structure [Cu(4,5-dicyanoimidazole)]n.(MeCN)0.5n (1). On the other hand, when MeCN/MeOH solvent mixture was used, a new coordination polymer [Cu(4,5-dicyanoimidazole)(MeCN)(CuI)]n (2) was formed. The crystallization yielded very different structures as determined by X-ray crystallography. In 1, the solvent molecule acetonitrile occupies the MOF pores via weak interactions, but in 2 it is coordinated to the metal center. Computational DFT calculations and topological charge density analysis were utilized to explore…
Despicable dark relics: generated by gravity with unconstrained masses
2019
We demonstrate the existence of a generic, efficient and purely gravitational channel producing a significant abundance of dark relics during reheating after the end of inflation. The mechanism is present for any inert scalar with the non-minimal curvature coupling $\xi R\chi^2$ and the relic production is efficient for natural values $\xi = {\cal O}(1)$. The observed dark matter abundance can be reached for a broad range of relic masses extending from $m \sim 1 {\rm k eV}$ to $m \sim 10^{8} {\rm GeV}$, depending on the scale of inflation and the dark sector couplings. Frustratingly, such relics escape direct, indirect and collider searches since no non-gravitational couplings to visible ma…
Effect of a social intervention of choice vs. control on depressive symptoms, melancholy, feeling of loneliness, and perceived togetherness in older …
2016
Objectives: This study examined effects of a social intervention on depressive symptoms, melancholy, loneliness, and perceived togetherness in community-dwelling Finnish older people. Method: Promotion of mental well-being in older people (GoodMood; ISRCTN78426775) was a single-blinded randomized control trial lasting 1.5 years. Two hundred and twenty-three persons aged 75–79 years reporting symptoms of loneliness or melancholy were randomized into intervention and control groups. The intervention group was allowed to choose among supervised exercise, social activity, or personal counseling. Follow-up measurements were conducted at the end of 6-month intervention, and at 3, 6, and 12 months…
Counselling for physical activity, life-space mobility and falls prevention in old age (COSMOS): protocol of a randomised controlled trial.
2019
IntroductionThe most promising way to promote active life years in old age is to promote regular participation in physical activity (PA). Maintaining lower extremity muscle function with good balance has been associated with fewer falls and the need of help from others. This article describes the design and intervention of a randomised controlled trial (RCT) investigating the effectiveness of a health and PA counselling programme on life-space mobility and falls rates in community-dwelling older adults at the Health Kiosk and/or Service Centre.Methods and analysisCommunity-dwelling men and women (n=450) aged 65 years and over with early phase mobility limitation will be recruited to a 24-mo…
(Un)sustainable creativity? Different manager-employee perspectives in the finnish technology sector
2020
The importance of creativity for working life and in organizations has increased in recent years. At the same time, the theme of sustainability has been intensely debated in research, society, and organizations. Together, creativity and sustainability have sometimes been described as a contradictory phenomenon: they are described in ways that place them in opposition to each other. To better understand creativity and sustainability and their differences from the perspective of people in different positions, we take advantage of a sociocultural approach in which we do not focus only on creative individuals but also on the impact of creativity on both organizational stakeholders and society a…
Kirjoittamisen opettamisen disiplinaarisista kamppailuista
2019
Kirjoittamisen rooli koulutuksen kaikilla tasoilla perusopetuksesta korkeakouluun on monimutkainen, hieman provosoivasti sen voi sanoa jopa perversoituneen. Kirjoittaminen on yhä vahvemmin mittaamisen, arvioinnin ja hallinnan väline. Kirjoittamisen roolilla opettajankoulutuksessa on suoria vaikutuksia siihen, miten tulevat opettajat toimivat koulussa. Keskityn artikkelissa kirjoittamisen opettamisen ja opiskelun disiplinaaririsiin kamppailuihin. Disipliini – kuri, järjestys, oppiaine – kuuluu kasvatuksen ydinkäsitteisiin niin käytännössä kuin teoriassakin. Tapausesimerkkinä käytän Jyväskylän yliopistossa vuosituhannen alusta toteutettua koulutus- ja tutkimusmallia, integraatiokoulutusta, jo…
Multisensory discourse resources : decolonizing ethnographic research practices
2020
Researchers have attempted to address the intersection of multisensory and multimodal discourse practices from an interactional perspective. This study argues for the value of experiential, non-interactional multisensory discourse resources and proposes a conceptual framework of multisensory discourse resources to bridge visual and family language ideology ethnography. A year-long ethnographic case study of three Nepalese families (immigrant and transmigrant), consisting of 150 h of observational data triangulated with qualitative interviews, posed two questions: (1) How do transnational families, in the homescape, use multisensory discourse resources to provide cultural, national, religiou…
