Unbiased Estimators and Multilevel Monte Carlo
2018
Multilevel Monte Carlo (MLMC) and unbiased estimators recently proposed by McLeish (Monte Carlo Methods Appl., 2011) and Rhee and Glynn (Oper. Res., 2015) are closely related. This connection is elaborated by presenting a new general class of unbiased estimators, which admits previous debiasing schemes as special cases. New lower variance estimators are proposed, which are stratified versions of earlier unbiased schemes. Under general conditions, essentially when MLMC admits the canonical square root Monte Carlo error rate, the proposed new schemes are shown to be asymptotically as efficient as MLMC, both in terms of variance and cost. The experiments demonstrate that the variance reduction…
Falls, Cognitive Function, and Balance Profiles of Singapore Community-Dwelling Elderly Individuals : Key Risk Factors
2017
Objective: This study compared occurrence of falls, cognitive function, and balance profiles across participants in elderly age categories, investigating associations between the 3 aspects in a sample of Singapore’s elderly population. Method: Community-dwelling elderly individuals (N = 385) were randomly recruited and grouped into “young-old (65-74 years),” “medium-old (75-84 years),” and “oldest-old (above 85 years)” groups. The Fallproof Health and Activity questionnaire, adapted Mini-Mental State Examination (MMSE), and Berg Balance Scale (BBS) tests were used to survey information related to falls, cognition, and balance profiles. Results: Findings revealed significant differences in M…

Building Worlds Together with Sound and Music : Imagination as an Active Engagement between Ourselves
2019
By conforming to the enactive approach to human cognition, and by adopting the Tia DeNora’s concept of human–music interaction as an “in-action” perspective, Kai Tuuri and Henna-Riikka Peltola explore socially extended imagining with sounds and music. This is done through a question of how “shared places” of imagining with sound are established and maintained. Defining the activity of imagining as an essentially dynamic and generative process that takes place in a social reality, the authors propose that the processes of imagining are not only individual but also become exhibited and jointly engaged in social dialogues as well. By first discussing the theoretical foundations of this shared …
Interactionist Approach to Visual Aesthetics in HCI
2021
Visual Aesthetics has gathered interest among scholars in HCI research. The growing interest stems from examinations of the aesthetic-usability effect (“what is beautiful is usable”), and possibly vice versa. Thus, numerous studies focus on understanding how we make sense and experience visual entities in interacting with technology. However, theoretical, and methodological stances vary, which impact conclusions of the studies conducted, and thus, affect design implications. Visual experience research in HCI lacks detailed conceptualizations of the constituents of visual experience and understanding of how these conceptualizations affect the overall research results through implicit methodo…

Neural correlates of morphological processing and its development from pre-school to the first grade in children with and without familial risk for d…
2022
Previous studies have shown that the development of morphological awareness and reading skills are interlinked. However, most have focused on phonological awareness as a risk factor for dyslexia, although there is considerable diversity in the underlying causes of this reading difficulty. Specifically, the relationship between phonology, derivational morphology, and dyslexia in the Finnish language remains unclear. In the present study, we used magnetoencephalography (MEG) to measure the brain responses to correctly and incorrectly derived Finnish nouns in 34 first grade Finnish children (21 typically developing and 13 with familial risk for dyslexia). In addition, we compared longitudinall…
Changing the ownership of ideas: Multimedial accomplishment of collaborative reflection in an organizational workshop
2022
Reflecting on work processes together with one's co-workers is becoming increasingly important in workplaces. This study examined collaborative reflection in the organizational context through analyzing a case of a complex workplace setting where an enterprise social media platform, talk-in-interaction, and handwriting were used to engage participants in the process of reflection. Drawing on the concept of remediation, the results show that collaborative reflection is interactionally accomplished through a multimedial activity chain, in which the ownership of presented ideas is transformed from individual ideas into shared views of the team. The study shows in detail how the process of coll…
Malliavin smoothness on the Lévy space with Hölder continuous or BV functionals
2020
We consider Malliavin smoothness of random variables f(X1), where X is a purejump Lévy process and the functionfis either bounded and Hölder continuousor of bounded variation. We show that Malliavin differentiability and fractional differentiability off (X1) depend both on the regularity offand the Blumenthal-Getoor index of the Lévy measure. peerReviewed
