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…

Cross-cultural adaptation and validation of the Kerlan-Jobe Orthopaedic Clinic shoulder and elbow score in Finnish-speaking overhead athletes

2022

Background The Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow score (KJOC) is developed to evaluate the shoulder and elbow function in overhead athletes. To date, the score has not been adapted into Finnish language. The aim of this study was to perform a cross-cultural adaptation of the Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow score (KJOC) into Finnish language and evaluate its validity, reliability, and responsiveness in overhead athletes. Methods Forward–backward translation method was followed in the cross-cultural adaptation process. Subsequently, 114 overhead athletes (52 males, 62 females, mean age 18.1 ± 2.8 years) completed the Finnish version of KJOC score, Disabilitie…

Validation of the swimming competence questionnaire for children

2020

Two studies were employed to test the reliability and validity of the Swimming Competence Questionnaire (SCQ) among primary school children. Study 1 was a cross-sectional survey in 4959 primary school children. Study 2 was a pre-post-test quasi-experiment among 1609 primary school children who underwent a 20-lesson learn-to-swim programme. In Study 1, exploratory structural equation modelling revealed excellent goodness-of-fit and scale reliability for a two-factor model comprising distance and skill factors, which supported the construct and convergent validity. SCQ scores were significantly and positively correlated with swimming outcomes (i.e., self-efficacy, intention, swimming frequenc…

Lääkinnällisen laitteen ohjelmistokehitys täydennetyllä Scrum-mallilla

2010

Tässä tutkielmassa perehdytään Scrum-mallin käyttöön lääkinnällisen laitteen ohjelmistokehityksessä. Lääkinnällisissä laitteissa olevien ohjelmistojen määrä on kasvanut viime vuosina paljon ja potilasvahinkojen myötä viranomaiset ovat asettaneet vaatimuksia lääkinnällisen laitteen ohjelmistokehitykselle. Tutkimuksessa tunnistetaan Euroopan unionin lääkinnällisten laitteiden direktiivin asettamat vaatimukset ohjelmistokehitykselle. Tärkeimmät vaatimukset liittyvät turvalliseen suunnitteluun, jota ohjataan riskienhallinnalla ja varmistetaan testauksella. Scrum-mallia täydennetään tunnistettujen vaatimusten pohjalta ja lopuksi esitetyn mallin arvioidaan täyttävän sille asetetut vaatimukset ja …

Doing gender and sexuality intersectionally in multimodal social media practices

2021

The chapter focuses on how members in participatory cultures engage in everyday, informal, and interest-driven social and discursive practices primarily on social media but also in ways that relate to the material and physical contexts of their lives. We show how social actors operating in these sites construct gender and sexuality intersectionally and multimodally. We argue that gender and sexuality are always constructed at intersections with other identity categories. With respect to both digital and physical participatory activities, multisemioticity is, in turn, necessary as an analytic perspective: it allows the investigation of how participants routinely draw on and deploy a range of…
