Investigating Some Construct Validity Threats to TALIS 2018 Teacher Job Satisfaction Scale: Implications for Social Science Researchers and Practitio…
2020
The credibility of findings ensuing from cross-sectional survey research depends largely on the validity and reliability of the research instruments. Critical attention to the quality of such instruments will ensure logical and valid results. The purpose of this article is to provide evidence for two methodological issues observed that are potential threats to construct validity of widely used Teaching and Learning International Survey (TALIS) 2018 data on teacher job satisfaction scale (TJSS). The first issue concerns reverse recoding of some items necessary to obtain a coherence covariance between these items and other items on the same subscale. The second issue concerns the addition of …
The Organizational Climate for Sustainable Commuting: An Italian Validation Study in the Academic Sector
2021
Promoting sustainable commuting represents a valuable contribution to tackle the climate crisis, and organizations could act as frontrunners in this regard. Accordingly, conceptualizing and measuring how organizational environments contribute to sustainable commuting has become relevant. This study aims to conceptualize and operationalize the construct of Organizational Climate for Sustainable Commuting (OCSC) and validate the OCSC scale in the Italian language. Data were gathered in an Italian university from 8542 participants. The validation was based on EFA and CFA, reliability, and aggregation indices analyses. To validate the scale, convergent, discriminant, internal construct, and cri…
ASR in Classroom Today : Automatic Visualization of Conceptual Network in Science Classrooms
2017
Automatic Speech Recognition (ASR) field has improved substantially in the last years. We are in a point never saw before, where we can apply such algorithms in non-ideal conditions such as real classrooms. In these scenarios it is still not possible to reach perfect recognition rates, however we can already take advantage of these improvements. This paper shows preliminary results using ASR in Chilean and Finnish middle and high school to automatically provide teachers a visualization of the structure of concepts present in their discourse in science classrooms. These visualizations are conceptual networks that relate key concepts used by the teacher. This is an interesting tool that gives…
La recherche en Management du Sport en « francophonie » : L’avènement d’un écosystème
2021
This paper aims to synthesize research on the Management of Sports Organizations (MOS) in France. Three parts structure this voluntarily simplifying contribution, very personal and collective at the same time through the direct and indirect contributions of many researchers. First of all, two historical parts between the 1960s and the 2000s provide a first disciplinary and then thematic perspective in order to make a French-speaking retrospective of the dynamics of scientific production. A last part in the form of a conclusion and an opening seeks to characterize the recent dynamics of MOS research (specialization, interaction, diversification) according to disciplines and/or objects of stu…
An Analysis of the Internal Organization of Facebook Groups
2019
With the rapid development and growth of online social networks (OSNs), researchers have been pushed forward to improve the knowledge of these complex networks by analyzing several aspects, such as the types of social media, the structural properties of the network, or the interaction patterns among users. In particular, a relevant effort has been devoted to the study and identification of cohesive groups of users in OSNs (also referred as communities) because they are the basic building block of each OSN. While several research works on groups in OSNs have mainly focused on identifying the types of groups and the contents created by their members, the analysis of internal organizations of …
Decision Making and Optimization for Inspection Planning under Parametric Uncertainty of Underlying Models
2013
Certain fatigued structures must be inspected in order to detect fatigue damages that would otherwise not be apparent. A technique for obtaining optimal inspection strategies is proposed for situations where it is difficult to quantify the costs associated with inspections and undetected failure. For fatigued structures, for which failures (fatigue damages) are only detected at the time of inspection, it is important to be able to determine the optimal times of inspection. Fewer inspections will lead to lower fatigue reliability of the structure upon demand, and frequent inspections will lead to higher cost. When there is a fatigue reliability requirement, the problem is usually to develop …
Cluster Algorithm Integrated with Modification of Gaussian Elimination to Solve a System of Linear Equations
2020
The data accumulation and their inhomogeneous distribution lead to the issue of large and sparse systems solving in various fields: industrials, emergency management, etc. Complex structure in the data error creates additional risk to obtain an adequate solution. To facilitate problem-solving, we describe the technique that is based on intellectual division of data with following application of cluster algorithm and the modification of Gaussian elimination to different portions of data. In this paper, we present results of developed technique that was applied to samples of synthetic and real data. We compare them with outcomes of other algorithms (intelligence and classical) by using of num…
Winteler, Jost (1846–1929)
2006
J Winteler was born in a village in the Swiss canton of Glarus. He studied philology in Jena, Germany. In his famous doctoral thesis, published in 1876, he described his native dialect of Kerenz. By analyzing the activity of the organs producing language (dialect) sounds, he was the founder of the so-called sound physiology (together with his teacher Eduard Sievers). In his prestructural approach, he noticed that there are sounds with and others without the capacity to change meaning. Purely structural terms were used already, such as Lautgegensatze (‘contrasts of sound’), (Sprach-)Bau ‘(linguistic) structure,’ and Konsonantensystem, Sprachsystem ‘system of consonants, of language.’ There w…
Structure and Evolution of a European Parliament via a Network and Correlation Analysis
2016
We present a study of the network of relationships among elected members of the Finnish parliament, based on a quantitative analysis of initiative co-signatures, and its evolution over 16 years. To understand the structure of the parliament, we constructed a statistically validated network of members, based on the similarity between the patterns of initiatives they signed. We looked for communities within the network and characterized them in terms of members’ attributes, such as electoral district and party. To gain insight on the nested structure of communities, we constructed a hierarchical tree of members from the correlation matrix. Afterwards, we studied parliament dynamics yearly, wi…
Logic for accumulation of design science research theory
2014
The paper introduces a structured logic for iterative and incremental accumulation of a design theory during a research project and across research programs. The logic is proposed to help researchers understand the links between parallel search spaces related to a particular design and linking to theoretical knowledge bases produced by previous search processes. The proposition rests on the notion that representing the structure and logic of design science research (DSR) theory using CIMO enables the elements of the knowledge base to be more easily evaluated, combined, and transferred between related search spaces. We view DSR theory development as an iterative and incremental social proces…
