COVID-19 and the future of work and organisational psychology
2021
Orientation: The coronavirus disease 2019 (COVID-19) pandemic has caused a ‘coronafication’ of research and academia, including the instrumentalisation of academic research towards the demands of society and governments. Whilst an enormous number of special issues and articles are devoted on the topic, there are few fundamental reflections on how the current pandemic will affect science and work and organisational psychology in the long run.Research purpose: The current overview, written by a group of members of the Future of Work and Organisational Psychology (FOWOP) Movement, focuses on the central issues relating to work and organisational psychology that have emerged as a result of the …
Spatio-temporal Vegetation Recuperation after a Grassland Fire in Lithuania
2013
The aim of this work is to study the spatio-temporal effects of a grassland fire in Lithuania. Immediately after the fire, a experimental plot was designed in a east-faced slope. Vegetation cover and height were measured 10, 17, 31 and 46 days after the fire (vegetation cover was only measured until 31 days after the fire because in the last measurement campaign the plot was completely covered). The results showed that vegetation recovered very fast. Ten days after the fire vegetation cover and height distribution were heterogeneous, decreasing with the time due to vegetation spread. Vegetation recovered was specially observed between 17 and 31 days after the fire due vegetation recuperatio…
Influence d'une supplémentation en vitamines sur le rendement de la locomotion après une épreuve d'ultratrail
2006
International audience; Aim: The purpose of this study was to study changes in gross efficiency of locomotion after a prolonged trail running race (3000 m up and 300 m down). The second purpose was to investigate the effectiveness of supplementation in vitamin on gross efficiency variability.Materials and methods: Twenty-two well-trained endurance runners took part in this study. They had to perform four sub maximal tests before, 24, 48 and 72 hours after the race in order to estimate gross efficiency of locomotion and a maximal contraction test in the same period. They were divided in two groups either with supplementation (Isoxan Endurance ®) or without (placebo).Results: In both groups w…
Classification of diabetes-related retinal diseases using a deep learning approach in optical coherence tomography
2019
Background and objectives: Spectral Domain Optical Coherence Tomography (SD-OCT) is a volumetric imaging technique that allows measuring patterns between layers such as small amounts of fluid. Since 2012, automatic medical image analysis performance has steadily increased through the use of deep learning models that automatically learn relevant features for specific tasks, instead of designing visual features manually. Nevertheless, providing insights and interpretation of the predictions made by the model is still a challenge. This paper describes a deep learning model able to detect medically interpretable information in relevant images from a volume to classify diabetes-related retinal d…
Hsp60 in embryonic and adult submandibular salivary gland: quantitative distribution patterns in normal tissue and comparison with benign and maligna…
2019
Introduction: Heat Shock Protein 60 (Hsp60) is a member of the chaperoning system that assists protein folding inside mitochondria and plays other roles beyond these organelles. It is implicated in the carcinogenic processes in various types of cancer. In human salivary glands, Hsp60 has not yet been measured or mapped in detail and its role in gland development and functioning is virtually unknown. Consequently, its potential as biomarker for gland diseases, including malignancies cannot be assessed. The S-100 protein, a known marker for schwannomas, has been found also in myoepithelial-cell carcinomas of the salivary glands. Here, we present our initial findings on the anatomic-histologic…
Activités cytotoxiques et pro-oxydantes d'acides gras à très longue chaîne sur des oligodendrocytes murins sauvages et déficients en Abcd1 et Acox1 :…
2010
X-ALD and P-NALD are two rare, peroxisomal metabolic and neurodegenerative diseases. ABCD1 and ACOX1 are known to be responsible for X-ALD and P-NALD, respectively. The actively demyelinating lesions in CNS, exhibited signs of oxidative stress and cell death. The accumulation of VLCFA in plasma and tissue is the biochemical common hallmark to both diseases. First, we characterized a murine oligodendrocytes cell line 158N to use it as a model. This 158N cell line which has characteristics of mature oligodendrocytes (expression of myelin proteins MOG, MBP, PLP), has also functional peroxisomes with Abcd1 and Acox1 proteins. Then, we studied the cytotoxic and pro-oxidative effects of VLCFA (C2…
Recent changes in measured wind in the NE Atlantic and variability of correlation with NAO
2010
The paper deals with wind measurements, recorded since the 1950s, at twelve meteorological stations along a transect near the westernmost European border, between 64° and 44° N. Extreme wind speed tends to decrease sharply near the northern boundary (at Reykjavick), near the middle of the study area (at Shannon and Valentia) and near the southern boundary (at Brest and Cap Ferret), to increase at Thorshavn, with less significant trends at the other stations. Average wind speeds confirm the above tendencies, with an additional increasing speed at Lerwick, Kirkwall, Malin Head, Belle-Ile and Cap Ferret. To compare changes in wind activity, the data have been subdivided into three periods: unt…
The political aspirations of the press of the Germans evicted from Silesia : as seen in the case of the Grafschafter Bote
2012
The integration process was very difficult for the millions of Germans evicted from the eastern territories at the end of WWII. The numerous newspapers that they published in FRG testify to their unique identity. This sector of the press reflects a large social group. One can find there the integration problems as well as the political claims of the evicted Germans. The Grafschafter Bote is a newspaper aimed at the Germans who were evicted from the County of Glatz (pol. Ziemia Kłodzka) in Silesia. It is an independent newspaper representing the most important associations and it has been published continually since 1950. The study of its content allows a better understanding of the evicted …
Etude des propriétés de coordination de nouveaux ligands macrocycliques vis-à-vis de cations métalliques en vue de l'utilisation de leurs complexes p…
2011
Noninvasive medical imaging techniques such as single-photon emission computed tomography (SPECT) or positron emission tomography (PET), are valuable tools for the development and validation of new therapeutic molecules. That approach requires the conjugation of a radioactive source emitting either y-rays or positrons with a biological tracer (e.g. DOTATOC). Among the potentially useful radionuclides available, 111In3+ (SPECT), 64Cu2+, and 68Ga3+ (PET) have attracted increasing attention over the last years for medical applications. To minimize the in vivo release of the radioactive cation by transmetalation or transchelation with biological ligands, it is essential to trap selectively the …
Une architecture générique de Systèmes de recommandation de combinaison d'items : application au domaine du tourisme
2011
This thesis gives a generalization of the recommendation principle of recommender systems. Instead of considering a recommendation as an item, it is considered as a combination of several items following a given pattern. A recommendation of a unique item is then a particular case of this type of recommendation. The proposed recommender system framework is based on an architecture derived from work in adaptive hypermedia systems. Three layers are defined: a semantic layer, a user layer and an intelligence layer. The semantic layer consists of two sub-layers, a sub-layer modeling the content according to the general knowledge of the domain and a sub-layer modeling the content according to the…
