Hair Mercury Levels Detection in Fishermen from Sicily (Italy) by ICP-MS Method after Microwave-Assisted Digestion
2015
A number of ninety-six hair samples from Sicilian fishermen were examined for total mercury detection by an Inductively Coupled Plasma Mass Spectrometry (ICP-MS) method. The mercury levels obtained were compared with mercury levels of 96 hair samples from a control group, in order to assess potential exposure to heavy metals of Sicilian fishermen due to fish consumption and closeness to industrial activities. Furthermore, the mercury levels obtained from hair samples were sorted by sampling area in order to verify the possible risks linked to the different locations. The overall mean concentration in the hair of the population of fishermen was6.45±7.03 μg g−1, with a highest value in a fish…
Collecting and Using Students’ Digital Well-Being Data in Multidisciplinary Teaching
2018
This article examines how students (N=198; aged 13 to 17) experienced the new methods for sensor-based learning in multidisciplinary teaching in lower and upper secondary education that combine the use of new sensor technology and learning from self-produced well-being data. The aim was to explore how students perceived new methods from the point of view of their learning and did the teaching methods provide new information that could promote their own well-being. We also aimed to find out how to collect digital well-being data from a large number of students and how the collected big data set can be utilized to predict school success from the students’ well-being data by using machine lear…
FastEMD–CCA algorithm for unsupervised and fast removal of eyeblink artifacts from electroencephalogram
2020
Abstract Online detection and removal of eye blink (EB) artifacts from electroencephalogram (EEG) would be very useful in medical diagnosis and brain computer interface (BCI). In this work, approaches that combine unsupervised eyeblink artifact detection with empirical mode decomposition (EMD), and canonical correlation analysis (CCA), are proposed to automatically identify eyeblink artifacts and remove them in an online manner. First eyeblink artifact regions are automatically identified and an eyeblink artifact template is extracted via EMD, which incorporates an alternate interpolation technique, the Akima spline interpolation. The removal of eyeblink artifact components relies on the el…
Automated and Online Eye Blink Artifact Removal from Electroencephalogram
2019
Eyeblink artifacts often contaminates electroencephalogram (EEG) signals, which could potentially confound EEG's interpretation. A lot offline methods are available to remove this artifact, but an online solution is required to remove eyeblink artifacts in near real time for EEG signal to be beneficial in applications such as brain computer interface, (BCI). In this work, approaches that combines unsupervised eyeblink artifact detection with Empirical Mode Decomposition (EMD) and Canonical Correlation Analysis (CCA) are proposed to automatically identify eyeblink artifacts and remove them in an online setting. The proposed approaches are analysed and evaluated in terms of artifact removal a…
Effects of Interobserver Variability on 2D and 3D CT- and MRI-Based Texture Feature Reproducibility of Cartilaginous Bone Tumors
2021
AbstractThis study aims to investigate the influence of interobserver manual segmentation variability on the reproducibility of 2D and 3D unenhanced computed tomography (CT)- and magnetic resonance imaging (MRI)-based texture analysis. Thirty patients with cartilaginous bone tumors (10 enchondromas, 10 atypical cartilaginous tumors, 10 chondrosarcomas) were retrospectively included. Three radiologists independently performed manual contour-focused segmentation on unenhanced CT and T1-weighted and T2-weighted MRI by drawing both a 2D region of interest (ROI) on the slice showing the largest tumor area and a 3D ROI including the whole tumor volume. Additionally, a marginal erosion was applied…
Metacognition, Metalanguage and Metapragmatics
1993
Abstract In this article, the author briefly reports John Flavell's analysis of metacognition. By attempting to integrate metalinguistic activities into this analysis, the author brings to light several interesting characteristics of the field of meta-linguistics and its current state of research. Firstly, it appears that, unlike other meta-abilities, the metalinguistic abilities are defined in terms of their objects. On this basis, metalinguistic activities are at least partially independent of other metacognitive activities. Secondly, it appears that the position of metapragmatics in relation to meta-linguistics is in need of greater clarification. In particular, it seems necessary to dra…

Once a journalist, not always a journalist? Causes and consequences of job changes from journalism to public relations
2019
Increasingly, journalists do not find permanent jobs and seek work in related fields, often in public relations. However, the two professions differ with regard to some of their normative functions: whereas journalists should report objectively and without bias, public relations practitioners are supposed to represent their clients’ particular interests. Hence, shifts from journalism to public relations have the potential for conflict. This study analyzes whether these shifts cause inter-role conflict and examines the reasons for the job changes. We conducted 17 qualitative semi-structured interviews with former journalists from Germany who have permanently transitioned into public relatio…
Note de synthèse : les analyses françaises des relations formation-emploi
1984
Los análisis franceses de las relaciones formación-empleo. - La época actual ha puesto la educación en el dominio de lo económico ; por esto hay numerosas investigaciones que tratan de la producción social de educación y de las relaciones formación-empleo. El autor presenta el desarrollo del aparato estadistico y de su estructuración ; las aproximaciones centradas sobre la inserción y el encaminamiento profesionales, las investigaciones macro-económicas o sociales que permiten la reconstrucción de los hechos observados respecto a las condiciones de la inserción profesional.
Les mesures de la relation formation-emploi
2015
National audience; Depuis les années 1960, l'analyse de la relation formation-emploi a fait en France l'objet de nombreux travaux, à partir notamment de grandes enquêtes statistiques comme les enquêtes emploi de l'INSEE ou les enquêtes du Céreq sur l'insertion des jeunes. Plusieurs mesures du lien formation-emploi ont été proposées, certaines d'entre elles se référant plus au moins explicitement à une logique adéquationniste qui a émergé lors des travaux des IVe et Ve Plans. Toutes les mesures montrent cependant que la relation formation-emploi est plurielle et que l'adéquation d'une formation à un emploi, à l'exception de quelques professions, n'est pas la norme sur le marché du travail.
