Validity of three smartwatches in estimating energy expenditure during outdoor walking and running.
2022
Commercially wrist-worn devices often present inaccurate estimations of energy expenditure (EE), with large between-device differences. We aimed to assess the validity of the Apple Watch Series 6 (AW), Garmin FENIX 6 (GF) and Huawei Watch GT 2e (HW) in estimating EE during outdoor walking and running. Twenty young normal-weight Chinese adults concurrently wore three index devices randomly positioned at both wrists during walking at 6 km/h and running at 10 km/h for 2 km on a 400- meter track. As a criterion, EE was assessed by indirect calorimetry (COSMED K5). For walking, EE from AW and GF was significantly higher than that obtained by the K5 (p < 0.001 and 0.002, respectively), but…
Dynaamisen tasapainotestin toistettavuus ja validointi
2017
Eija Hartikainen. 2017. Dynaamisen tasapainotestin toistettavuus ja validointi. Liikuntabiologian tieteenalaryhmä, Jyväskylän yliopisto, Biomekaniikan Pro gradututkielma, 114s. Tasapaino on kokonaisuus, mitä ohjataan useiden eri säätelyjärjestelmien avulla. Näin ollen tasapainon tutkimiseen kehitettyjen mittausvälineiden on syytä mitata tasapainoa toistettavasti ja validisti. Tässä tutkielmassa selvitettiin Dynaamisen tasapainotestin toistettavuutta ja validiteettia 20 tutkittavalla, joiden keski-ikä oli 28,6 (±6,3). Tasapainotesti suoritettiin moottoroidulla voimalevyllä, jolla horjutettiin tutkittavien tasapainoa aiheuttamalla 32 ulkoista häiriötä liikuttamalla voimalevyä eteen- ja taakse…
Sähkökoneen osaluettelon validointityökalun kehittäminen tietämyslähtöisen suunnittelun avulla
2011
ABB Oy Moottorit ja Generaattorit -liiketoimintayksikkö valmistaa sähkömoottoreita ja generaattoreita vaihteleviin asiakastarpeisiin. Koneet suunnitellaan osista, jotka muodostetaan puurakenteeksi tuotetiedon hallintajärjestelmään (PDM – Product Data Management). Puurakennetta kutsutaan yleisesti osaluetteloksi. Osaluettelon suunnittelu on monimutkainen prosessi ja sen sisältämä tietämys on jakaantunut moniin tietolähteisiin. ABB Oy:n tarpeena on kehittää järjestelmä, joka kokoaa hajanaisen tietämyksen ja validoi suunniteltavan osaluettelon tämän tietämyksen avulla. Tässä tutkimuksessa on perehdytty tietämyslähtöiseen suunnitteluun ja sen menetelmiin. Tietämyslähtöinen suunnittelu tähtää tu…

The structural validity of the Finnish version of the Disabilities of the Arm, Shoulder and Hand : a Rasch model analysis
2020
Abstract Introduction: The construct validity of the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH) has previously been questioned. The purpose of this study was to evaluate the measurement properties of the Finnish version of the DASH for assessing disability in patients with hand complaints using Rasch Measurement Theory. Methods: A cohort of 193 patients with typical hand and wrist complaints were recruited at a surgery outpatient clinic. The DASH scores were analysed using the Rasch model for differential item functioning, unidimensionality, fit statistics, item residual correlation, coverage/targeting and reliability. Results: In the original DASH questionnaire, the it…
An Updated Guideline for Assessing Discriminant Validity
2022
Discriminant validity was originally presented as a set of empirical criteria that can be assessed from multitrait-multimethod (MTMM) matrices. Because datasets used by applied researchers rarely lend themselves to MTMM analysis, the need to assess discriminant validity in empirical research has led to the introduction of numerous techniques, some of which have been introduced in an ad hoc manner and without rigorous methodological support. We review various definitions of and techniques for assessing discriminant validity and provide a generalized definition of discriminant validity based on the correlation between two measures after measurement error has been considered. We then review te…
Survey data for the validation of a perceived visual usability (PVU) measurement
2022
This dataset is part of a publication (Differentiating Perceived Usability from Aesthetics in Visual Experience – Validation of a Perceived Visual Usability Measurement). Data concerning confirmatory factor analysis (CFA) utilised in the measurement validation is freely available. Data for the CFA was collected via Prolific, an online survey platform. Thirty-three different surveys were created with the Webropol survey tool, all with different stimulus. Participants (N = 330) answered to the 33 surveys (161 female, 163 male, age range = 18-53, M = 25.8, SD = 7.0). The CFA dataset contains variables of Participant id, Stimulus, Age, Gender, Country, Native-English, and survey scales comprise…

StartCards — A method for early-stage software startups
2023
Publisher Copyright: © 2023 The Author(s) Context: Software startups are important drivers of economy on a global scale, and have become associated with innovation and high growth. However, the overwhelming majority of startups ends in failure. Many of these startup failures ultimately stem from software engineering issues, and requirements engineering (RE) ones in particular. Despite the emphasis placed on the importance of RE activities in the startup context, many startups continue to develop software without a clear market or customer, having never had meaningful contact with their would-be customer. Objective: We develop a method aimed at early-stage startups that is intended to help s…
