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…

Methodological Guidelines Designed to Improve the Quality of Research on Cross-Country Skiing

2021

AbstractCross-country (XC) ski races involve a variety of formats, two different techniques and tracks with highly variable topography and environmental conditions. In addition, XC skiing is a major component of both Nordic combined and biathlon competitions. Research in this area, both in the laboratory and field, encounters certain difficulties that may reduce the reliability and validity of the data obtained, as well as complicate comparisons between studies. Here, 13 international experts propose specific guidelines designed to enhance the quality of research and publications on XC skiing, as well as on the biathlon and Nordic combined skiing. We consider biomechanical (kinematic, kinet…

Meta-Study

2022

Meta-study is a method for analysing the content and the process of knowledge production in a body of qualitative research. Conducting a meta-study involves four steps: (1) meta-data-analysis which involves the study of empirical findings; (2) meta-method which examines the epistemological soundness and rigour of methods; (3) meta-theory which examines the structures, assumptions, and principles underpinning the primary research studies; and (4) meta-synthesis which brings the three steps together and considers the plausibility of existing accounts, what has been neglected, and what new avenues have been opened for advancing knowledge. Qualitative researchers in sport and exercise psycholog…

Statistical modelling of selective non-participation in health examination surveys

2018

Health examination surveys aim to collect reliable information on the health and risk factors of a population of interest. Missing data occur when some invitees do not participate the survey. If non-participation is associated with the variables to be studied, then the estimates based only on the participants cannot be generalised to the population of interest. In this case, the estimates have selection bias, which misleads the decision-makers. The purpose of this thesis is to develop statistical methods to reduce the selection bias in the cross-sectional data using additional data sources. The data, which we use, comes from the National FINRISK Study, and we aim to estimate the prevalences…

Nuorten yksilöllistyvät kulttuurivalinnat : tutkimus sosiaalisten taustatekijöiden ja yksilöllisten valintojen vaikutuksesta nuorten kulttuuri- ja ta…

2014

Tämä tutkimus ottaa osaa ajankohtaiseen kulttuuripolitiikan tutkimuksessa käytävään keskusteluun sosiaalisten rakenteiden ja yksilöllisten tekijöiden vaikutuksesta kulttuurivalintojen muodostumiseen. Tutkimuksen tehtävänä on selvittää, miten sosiaaliset taustatekijät ja yksilölliset valinnat vaikuttavat suomalaisten 15–29-vuotiaiden nuorten kulttuuri- ja taidelaitosten tärkeinä pitämiseen. Aineistona on vuoden 2009 Nuorisobarometri (n=1900). Tutkimustehtävään vastataan kahden tutkimusasetelman avulla. Ensimmäisessä tutkimusasetelmassa selvitetään kulttuuri- ja taidelaitosten tärkeinä pitämistä ennustavia tekijöitä. Toisessa tutkimusasetelmassa tutkitaan, mitkä tekijät erottelevat kulttuuri-…
