VALIDITY AND RELIABILITY OF MEASUREMENTS OF THE PARAMETERS OF SMILE AESTHETICS: A COMPARISON BETWEEN DIGITAL AND PLASTER MODELS
2020
This study aims to evaluate the validity and reliability of the TRIOS3 Color intraoral scanner (3Shape A/S, Copenhagen, Denmark) and its associated Ortho Analyzer™ software in measuring parameters of smile aesthetics compared with measurements on plaster casts. The study sample comprised plaster casts and digital models obtained from 30 subjects. Height (H), mesiodistal diameter (MDD) and connecting space (CS) of the anterior teeth were measured with a digital calliper on the plaster models and with the orthodontic software on the digital models. Validity was assessed using a 2-tailed paired t-test; the reliability of measurements for intra-examiner was evaluated with the Intra-class Correl…
The measurement invariance of Job Diagnostic Survey (JDS) across three university student groups
2016
Purpose: The main purpose of this study is to apply a multigroup confirmatory analysis to examine the measurement invariance (MI) of the adapted version of the Job Diagnosis Survey (JDS) as a measurement tool that analyses the relationship between the features of teaching methodologies with university students’ motivation and satisfaction across data collected on different degrees and academic years. Design/methodology/approach: Confirmatory factor analysis was carried out using a multigroup structural equation model, using the program EQS 6.1 to test the invariance of the adapted version of JDS in a sample constituted by 535 student of a Spanish public university. The assessment of invaria…
Thermodynamic correction of particle concentrations measured by underwing probes on fast-flying aircraft
2016
Particle concentration measurements with underwing probes on aircraft are impacted by air compression upstream of the instrument body as a function of flight velocity. In particular, for fast-flying aircraft the necessity arises to account for compression of the air sample volume. Hence, a correction procedure is needed to invert measured particle number concentrations to ambient conditions that is commonly applicable to different instruments to gain comparable results. In the compression region where the detection of particles occurs (i.e. under factual measurement conditions), pressure and temperature of the air sample are increased compared to ambient (undisturbed) conditions in certain …
The Changing Roles of Academic Leaders: Decision-Making, Power, and Performance
2019
AbstractMajor reforms in the Nordic countries have increased the formal autonomy of higher education institutions (HEIs) to make decisions over their own activities, both academic core tasks and managerial/administrative activities. The issue addressed in this chapter is how these changes have affected the role of the academic leader. Across the four countries, we see clear signs of change regarding academic leadership comprising a mix of institutional logics in the interviews: the professional, collegial traditional academic leadership, which is based on rotating systems, election among peers, and collegial decision-making, has been complemented with, and in some places replaced by, a mana…
Measuring self‐regulated learning in a junior high school mathematics classroom : Combining aptitude and event measures in digital learning materials
2023
Background Measurement of students' self-regulation skills is an active topic in education research, as effective assessment helps devising support interventions to foster academic achievement. Measures based on event tracing usually require large amounts of data (e.g., MOOCs and large courses), while aptitude measures are often qualitative and need careful interpretation. Precise and interpretable evaluation of self-regulation skills in a normal K-12 classroom thus poses a challenge. Objectives The present study proposes and explores a learning analytics method of combining aptitude and event measures to evaluate student's self-regulation skills. Methods An explorative learning analytics s…
NEW METHODS DEEPENING UNDERSTANDING OF STUDENTS' EXPERIENCES AND THEIR RELATION TO PHYSIOLOGICAL ALERTNESS VARIATIONS DURING LEARNING
2019
In this study we explored whether physiological measurement technologies could be used in a combination with traditional educational research methods to investigate learning experiences. We aimed, first, to explore individual physiological reactions during learning and how these reactions relate to experiences, emotions and contexts of learning and, second, to test new methodology and its suitability for investigating learning. The data was collected during a teacher education programme in a Finnish university. A total of 14 students participated in the study. The data was collected during two contact periods of three days and the weekends after them, ten days in total. We used a mixed meth…
METHODOLOGY DEVELOPMENT IN ADULT LEARNING RESEARCH. COMBINING PHYSIOLOGICAL REACTIONS AND LEARNING EXPERIENCES IN SIMULATION-BASED LEARNING ENVIRONME…
2020
We aim to clarify whether physiological measurement technologies can be used in combination with traditional educational research methods to investigate learning experience. We developed an interdisciplinary research design for multilevel investigation of adult learning experience. We collected data in aviation simulations and forestry simulations, to show both similarities and differences between different learning situations. Both settings utilize high quality virtual simulations allowing learning to occur in near authentic situations. The learning situations were structured pedagogically in a similar way. They involve learner-instructor interaction in a one-on-one setting and follow a tr…
Legitimacy and relevance of a performance measurement system in a Finnish public-sector case
2019
Purpose This study investigates the difficulties involved in translating stakeholder expectations into action and maintaining legitimacy through the use of a performance measurement system (PMS) created in a Finnish regional development company (RDC). This longitudinal case study illustrates the fluctuating and socially constructed nature of legitimacy in the public sector. Design/methodology/approach This qualitative case study longitudinally analyzes the various developments occurring during and after the development of a PMS system for the case organization. Empirical data include interviews, workshops, observation and other materials relating to the case organization. Findings The init…
Ledrappier-Young formula and exact dimensionality of self-affine measures
2017
In this paper, we solve the long standing open problem on exact dimensionality of self-affine measures on the plane. We show that every self-affine measure on the plane is exact dimensional regardless of the choice of the defining iterated function system. In higher dimensions, under certain assumptions, we prove that self-affine and quasi self-affine measures are exact dimensional. In both cases, the measures satisfy the Ledrappier-Young formula. peerReviewed
Równość jako wymiar dobrego rządzenia na poziomie gminnym - propozycja konceptualizacji i pomiaru
2018
the discourse on good governance is overvvhelmingly dominated by countrywide approach, while botli a methodological and axiological concerns point to the nced for a stronger concentration on local governance. 'i hus, the purpose of this paper is an application of a concept of good governance to the local level of the Polish commune. Firstly, the main sources of good governance concept are presented, including its cmcial. dimcnsions being a normalive point of reference for evaluating whether the governancc is good 01* bad. Secondly, by analyzing the collection of data about variety of tools dcsigncd to measurc ąuality of local governance worldwide, the author picks one of the local governanc…
