Pedagogical approaches for e-assessment with authentication and authorship verification in Higher Education

2019

Checking the identity of students and authorship of their online submissions is a major concern in Higher Education due to the increasing amount of plagiarism and cheating using the Internet. The literature on the effects of e-authentication systems for teaching staff is very limited because it is a novel procedure for them. A considerable gap is to understand teaching staff' views regarding the use of e-authentication instruments and how they impact trust in e-assessment. This mixed-method study examines the concerns and practices of 108 teaching staff who used the TeSLA—Adaptive Trust-based e-Assessment System in six countries: the UK, Spain, the Netherlands, Bulgaria, Finland and Turkey.…

Quasi-periodical kinetic instabilities in minimum-B confined plasma

2022

We present the results of an experimental investigation of quasi-periodical kinetic instabilities exhibited by magnetically confined electron cyclotron resonance heated plasmas. The instabilities were detected by measuring plasma microwave emission, electron losses, and wall bremsstrahlung. The instabilities were found to be grouped into fast sequences of periodic plasma losses, separated by ∼100 µs between the bursts, followed by 1–10 ms quiescent periods before the next event. Increasing the plasma energy content by adjusting the plasma heating parameters, in particular the magnetic field strength, makes the instabilities more chaotic in the time domain. Statistical analysis reveals that …

The use of in-line quantitative analysis to follow polymer processing

2009

In this work it is presented three applications of real time analysis during extrusion process using an optical device developed by our research group, which applies the concepts of light extinction. Monitoring of polymer blends morphology takes place to infer data concerned to dispersed phase size and concentration. The detector also enables information about melting temperature of polymer during extrusion and the level of viscous heating, and the exfoliation step during processing of a polymer-clay nanocomposite.

LIFE CYCLE ASSESSMENT EXPERIENCES FOR SOLAR HEATING AND COOLING SYSTEMS

2018

Solar heating and cooling systems can significantly contribute to the energy and climate European goals. A complete assessment of this contribution needs the analysis of these systems from a life-cycle perspective, in order to estimate the energy and environmental costs of their manufacturing and end-of-life, and to compare these costs with the benefits obtained during operation. A well-established methodology to fulfil this task is the Life Cycle Assessment (LCA). The paper describes some LCA experiences of solar heating and cooling systems, developed within the Task 53 “New generation solar cooling & heating systems (PV or solar thermally driven systems)” of the International Energy A…

ROMANIAN TAXPAYERS’ INCLINATION TO TAX CHEATING

2011

Any taxpayer lives with the feeling of being stolen when it finds that tax revenues are not used effectively and corruption is prevalent everywhere. Tax psychology appears often as an explanation of tax payers’ behavior in relation to taxation. This paper aims to underline the disparity between the degree of verbal fiscal morality declared by the Romanians in international surveys (World Values Survey) and the degree of factual fiscal morality provided by annual reports of National Tax Administration Agency of Romania. Results of the survey undertaken at the international level cannot be extrapolated to the complex territorial space with millions of working individuals and corporate taxpaye…

Moral Attitudes Predict Cheating and Gamesmanship Behaviors Among Competitive Tennis Players

2017

Background: The present study tested Lee et al.’s (2008) model of moral attitudes and cheating behavior in sports in an Italian sample of young tennis players and extended it to predict behavior in actual match play. In the first phase of the study we proposed that moral, competence and status values would predict prosocial and antisocial moral attitudes directly, and indirectly through athletes’ goal orientations. In the second phase, we hypothesized that moral attitudes would directly predict actual cheating behavior observed during match play.\ud \ud Method: Adolescent competitive tennis players (N = 314, 76.75% males, M age = 14.36 years, SD = 1.50) completed measures of values, goal or…
