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 …
Digital Technologies for virtual recomposition. The case study of Serpotta stuccoes.
2014
The matter that lies beneath the smooth and shining surface of stuccoes of the Serpotta family, who used to work in Sicily from 1670 to 1730, has been thoroughly studied in previous papers, disclosing the deep, even if empirical, knowledge of materials science that guided the artists in creating their masterworks. In this work the attention is focused on the solid perspective and on the scenographic sculpture by Giacomo Serpotta, who is acknowledged as the leading exponent of the School. The study deals with some particular works of the artist, the so-called “teatrini” (Toy Theater), made by him for the San Lorenzo Oratory in Palermo. On the basis of archive documents and previous analogica…
Bullying in Students Who Stutter: The Role of the Quality of the Student–Teacher Relationship and Student’s Social Status in the Peer Group
2020
Children who stutter are at risk of being excluded, rejected, or bullied at school because of their impairment. The aim of the current research is to assess the relationship between students and te...
Determinants of user behaviour and recommendation in social networks
2014
Purpose – The purpose of this paper is to analyse the determinants of social network use behaviour using Theory of Planned Behaviour (TPB) and Uses and Gratifications Theory. Design/methodology/approach – A quantitative study was carried out with data gathered by personal interview using a structured questionnaire. Relationships proposed in the theoretical model were estimated through structural equation models. In total, 811 users of social networks over 14 and residents in Spain were part of the sample. Findings – Results indicate that use attitude and the subjective norm, both TPB variables, directly and significantly influence social network loyalty. Thus, network loyalty can be achiev…
Psychometric properties of the Spanish version of the Temporal Satisfaction with Life Scale (TSLS): A study on elderly attending to university progra…
2015
Several measures have been developed for the operalization of well-being, standing out the Satisfaction With Life Scale (SWLS). To cope with some of its problems the Temporal Satisfaction with Life Scale (TSLS) was developed. The aim of this study is to present and validate the Spanish version of the TSLS, in a sample elderly attending to University programs. The sample was composed of 737 elderly. Together with the TSLS, an indicator of general life satisfaction and the SF-8 Health Scale were used. Analyses included the study of factorial validity, estimations of reliability and external validity. Results of the confirmatory factor analysis were adequate: χ2(87)=454.593 (p<.001), CFI=.9…
Validation of an explicative model of the successful aging process with psychological, physical, relational, and leisure variables
2015
Increasingly, research on the aging process tends to adopt a dual perspective emic (specific to a culture) and etic (universal), requiring further studies to address this cross-cultural approach. The aim is to obtain an empirical answer to the question of whether a model of successful aging raised from a different context such as the Taiwanese context, is suitable to represent this process in our elders. The sample consisted of 737 elderly. Socio-demographic-data and different scales to assess life satisfaction, leisure, health, and social support were collected. A structural equation model taken from Lee et al. (2011), in which leisure, health and social support predicted life satisfaction…
In Silico Design, Synthesis and Biological Evaluation of Anticancer Arylsulfonamide Endowed with Anti-Telomerase Activity
2022
Telomerase, a reverse transcriptase enzyme involved in DNA synthesis, has a tangible role in tumor progression. Several studies have evidenced telomerase as a promising target for developing cancer therapeutics. The main reason is due to the overexpression of telomerase in cancer cells (85–90%) compared with normal cells where it is almost unexpressed. In this paper, we used a structure-based approach to design potential inhibitors of the telomerase active site. The MYSHAPE (Molecular dYnamics SHared PharmacophorE) approach and docking were used to screen an in-house library of 126 arylsulfonamide derivatives. Promising compounds were synthesized using classical and green methods. Com…
Quantum Monte Carlo Simulations of Models Related to High-Tc Superconductivity on a Transputer Network
1991
Much of the insight into the low temperature behaviour of two-dimensional quantum antiferromagnets has been recently obtained by extensive Monte Carlo. These models are relevant in the study of the magnetic behaviour of high Tc compounds containing copper-oxide layers. While of little technical importance, the physical properties of these models are certainly important for the understanding of the new type of behaviour that leads to superconductivity under certain conditions.
Change in Newcomers' Supervisor Support and Socialization Outcomes After Organizational Entry
2009
Using a four-wave longitudinal research design and a latent growth modeling approach, we modeled change in newcomers' perceived supervisor support and socialization outcomes (role clarity, work mas...
Fusing storage and computing for the domain of business intelligence and analytics: research opportunities
2015
With the growing importance of external and shared data, the set of requirements for Business Intelligence and Analytics (BIA) is shifting. Current solutions still come with shortcomings, esp. In multi-stakeholder environments where sensitive content is exchanged. We argue that a new level in the evolution of BIA can be unlocked by tearing down the barriers between storage and computing based on upcoming storage technologies. In particular, we propose a revitalization of ideas from object-oriented databases. We present results from a joint project that aimed at delineating design options for BIA solutions built upon this idea. The paper outlines the interplay of various architectural layers…
