Physical education teacher educators’ views regarding the purpose(s) of school physical education
2015
The aim of this paper was to gain an understanding of the views of a group of physical education teacher educators on the purpose(s) of school physical education and whether, how and why these views have changed over time. Semi-structured individual interviews were carried out with thirteen physical education teacher educators; a fourteenth participant responded to interview questions in writing. Participants were based in seven countries: Belgium, Finland, Germany, Ireland, New Zealand, Switzerland and the USA. A relative consensus on the overarching purpose of physical education was evident, centred on physical education preparing young people for a lifetime of physical activity. The fram…
Problem Transformation Methods with Distance-Based Learning for Multi-Target Regression
2020
Multi-target regression is a special subset of supervised machine learning problems. Problem transformation methods are used in the field to improve the performance of basic methods. The purpose of this article is to test the use of recently popularized distance-based methods, the minimal learning machine (MLM) and the extreme minimal learning machine (EMLM), in problem transformation. The main advantage of the full data variants of these methods is the lack of any meta-parameter. The experimental results for the MLM and EMLM show promising potential, emphasizing the utility of the problem transformation especially with the EMLM. peerReviewed
El proyecto de un pórtico clasicista para la iglesia de los Santos Juanes de Valencia y su impacto en el entorno urbano (1788-1856)
2020
In the year 1788, the parish of Los Santos Juanes in Valencia proposed to the City Council the erection of same classical-style portico in order to beautify its outer eastern façade, surrounding the head of the temple and relying on the Plaza del Mercado. This portico was never built, but there would be an impact of such an architectural purpose in subsequent reform plans of that outstanding urban location.
Cuerpos de energía: Formas alternativas de ser-en-el-mundo
2020
Based on an ethnographic approach, this paper explores how members of a new age spiritual movement known as ?Llave Mariana? (LLM) build and experience their bodies. At the same time, it develops a thick description of their ritual practices and later it analyzes, delving fundamentally into the phenomenological perspective, how these members shape and transform their forms of self-perception, experience, and representation of others and the environment. Finally, it considers the implications these spiritual practices have in the search and consolidation of alternative ways of being-in-the-world
Identifying Critical Determinants of ‘Digital Customer Services’ Usage – An Exploratory Study
2019
Digital technology has reinvented retail business as well as commerce. This study aims to examine consumers’ perception and usage of digital customer services (DCS) and investigate three significant post-adoption and marketing consequences: simplicity, awareness, and usefulness. Using a purposeful sampling technique, 10 semi-structured, in-depth interviews were conducted with banking customers in Finland in January 2019. The research findings suggest that simplicity regarding DCS occupies a key position in their prolonged use, while awareness and usability are also important. This study offers some valuable theoretical and managerial implications and suggests an agenda for future research. …
Developing a metatheoretical framework for second language development : a cultural-historical theory and dynamic systems theory perspective
2017
The main aim of this article-based dissertation is to construct and articulate a dialectical metatheoretical architecture for the study of second language development termed Purposive-Historical Systems Theory (PHiST) invoking, inter alia, the axiomatic imperatives of dynamic systems theory (DST), Vygotskian cultural-historical theory (CHT), and Pepperian root metaphor theory (RMT). Specifically, it primarily purports, first, to demonstrate the tenability of a dialectical synthesis of DST and CHT; second, to philosophize on the fundamental contours of PHiST; third, to apply a novel metatheoretical perspective, as a quintessential example, to reconceptualizing the seminal construct of the Zo…
Personal use of technology at work : a literature review and a theoretical model for understanding how it affects employee job performance
2021
Employee personal use of technology at work (PUTW)—defined as employees’ activities using organisational or personal IT resources for non-work-related purposes while at work—is increasingly common in organisations. Our review of existing PUTW studies (n = 137) suggests that previous studies widely discussed PUTW outcomes, antecedents, and policies. The literature review also indicates that previous studies have proposed opposing viewpoints regarding the effect of PUTW on employee job performance, but few studies offered empirical evidence. Consequently, the conditions under which PUTW can increase or decrease employee job performance have not been discussed. We develop a theoretical model (…
Numerical Simulations of the Flow Field of a Submerged Hydraulic Jump over Triangular Macroroughnesses
2021
The submerged hydraulic jump is a sudden change from the supercritical to subcritical flow, specified by strong turbulence, air entrainment and energy loss. Despite recent studies, hydraulic jump characteristics in smooth and rough beds, the turbulence, the mean velocity and the flow patterns in the cavity region of a submerged hydraulic jump in the rough beds, especially in the case of triangular macroroughnesses, are not completely understood. The objective of this paper was to numerically investigate via the FLOW-3D model the effects of triangular macroroughnesses on the characteristics of submerged jump, including the longitudinal profile of streamlines, flow patterns in the cavity regi…
Levels and Potential Health Hazards of Chlorinated Pesticidesin Surface Water Samples of Charsadda Area of Pakistan Using SPME-GC-ECD Technique
2021
In the present study, we determined the levels of chlorinated pesticide residues in surface water samples collected from the Charsadda district (KPK, Pakistan). SPME-GC-ECD with COMBI PAL CTC autosampler was used for extraction and analysis of 20 organochlorine pesticides in the collected water samples. For maximum efficiency of the SPME procedure, several parameters were studied, including the extraction and desorption time of the fiber, solution pH, agitation of samples, and stirring speed, etc. This method showed good liner response, with R2 values in the range of 0.9887 to 0.9999 for all pesticides. This method also provided good percent recoveries at 1 µg L−1 (87.5 to 106.0%) and at 2 …
Excess electronic recoil events in XENON1T
2020
We report results from searches for new physics with low-energy electronic recoil data recorded with the XENON1T detector. With an exposure of 0.65 t-y and an unprecedentedly low background rate of $76\pm2$ events/(t y keV) between 1 and 30 keV, the data enables sensitive searches for solar axions, an enhanced neutrino magnetic moment, and bosonic dark matter. An excess over known backgrounds is observed at low energies and most prominent between 2 and 3 keV. The solar axion model has a 3.4$\sigma$ significance, and a 3D 90% confidence surface is reported for axion couplings to electrons, photons, and nucleons. This surface is inscribed in the cuboid defined by $g_{ae}<3.8 \times 10^{-12}$,…
