Geography Tests for Grade 7 in Accordance with Contemporary Educational Purposes
2018
Pārbaudes darbs – ir svarīgs mācību rezultātu novērtēšanas instruments, kuram ir jāatbilst sabiedrības vajadzībām un skolēnu īpašībām. Informācijas pieejamība un strauja maiņa izvirza pārbaudes darbu sastādītājiem jaunas prasības, kas ir labāk piemērotas skolēnu spēju novērtēšanai. Mūsdienās ir svarīgi novērtēt skolēnu augstākā izziņu līmeņa jeb domāšanas spējas: prasmes operēt ar informāciju, analizēt, risināt problēmsituācijas, radoši un kritiski domāt. Pētījuma rezultātā ir noskaidrots, kā pārbaudes darbi ģeogrāfijā 7.klasēm nespēj nodrošināt augstāka līmeņa prasmju novērtēšanu, bet pašiem skolēniem ir grūtības šādu spēju novērtējošo uzdevumu izpildē. Tomēr augstākā līmeņa uzdevumu izpil…
Automated Characterization of Mouth Activity for Stress and Anxiety Assessment
2016
International audience; Non-verbal information portrayed by human facial expression, apart from emotional cues also encompasses information relevant to psychophysical status. Mouth activities in particular have been found to correlate with signs of several conditions; depressed people smile less, while those in fatigue yawn more. In this paper, we present a semi-automated, robust and efficient algorithm for extracting mouth activity from video recordings based on Eigen-features and template-matching. The algorithm was evaluated for mouth openings and mouth deformations, on a minimum specification dataset of 640x480 resolution and 15 fps. The extracted features were the signals of mouth expa…
Dietary exposure in utero and during lactation to a mixture of genistein and an anti-androgen fungicide in a rat mammary carcinogenesis model
2015
Endocrine disruptors may play substantial roles in the high incidence of breast cancer. We previously described how early exposure to the mixture of phytoestrogen genistein (G) and the anti-androgen vinclozolin (V) affects peripubertal mammary development. This study evaluates the carcinogenic potential of exposure to V alone or associated with G from conception until weaning in Wistar rats. Dams were exposed to V, G or GV during pregnancy/lactation. At PND50 offspring were treated with DMBA[7,12-dimethylbenz(a)anthracene]. V or GV maternal exposure decreased number of DMBA-induced mammary tumors in the offspring, without significant modifications in tumor incidence, multiplicity and latenc…
Dexipm-Grapevine : a multicriteria assessment tool of the sustainability for grapevine farming systems
2015
The development of innovative farming systems to reach new goals of agricultural sustainability needs new methods for efficiency assessment. DEXiPM-Grapevine© is a multicriteria assessment tool for overall sustainability of grapevine farming systems adapted from DEXiPM arable crops (Pelzer et al, 2012). DEXiPM-Grapevine© was implemented during the European PURE Project 2012-2015 (Integrated Pest Management (IPM) solutions in agriculture) in order to assess and compare various innovative grapevine systems. This model includes 65 basic attributes describing the cropping system, which are then combined into 97 aggregated attributes, designed to assess the economic, social and environmental per…
Advanced 3D movement analysis algorithms for robust functional capacity assessment.
2017
SummaryObjectives: We developed a novel system for in home functional capacities assessment in frail older adults by analyzing the Timed Up and Go movements. This system aims to follow the older people evolution, potentially allowing a forward detection of motor decompensation in order to trigger the implementation of rehabilitation. However, the pre-experimentations conducted on the ground, in different environments, revealed some problems which were related to KinectTM operation. Hence, the aim of this actual study is to develop methods to resolve these problems.Methods: Using the KinectTM sensor, we analyze the Timed Up and Go test movements by measuring nine spatio-temporal parameters, …
Study and Comparison of Surface Roughness Measurements
2014
Journées du Groupe de Travail en Modélisation Géométrique (GTMG'14), Lyon; This survey paper focus on recent researches whose goal is to optimize treatments on 3D meshes, thanks to a study of their surface features, and more precisely their roughness and saliency. Applications like watermarking or lossy compression can benefit from a precise roughness detection, to better hide the watermarks or quantize coarsely these areas, without altering visually the shape. Despite investigations on scale dependence leading to multi-scale approaches, an accurate roughness or pattern characterization is still lacking, but challenging for those treatments. We think there is still room for investigations t…
Recent progress in understanding physical and chemical properties of African and Asian mineral dust
2011
International audience; This paper presents a review of recently acquired knowledge on the physico-chemical properties of mineral dust from Africa and Asia based on data presented and discussed during the Third International Dust Workshop, held in Leipzig (Germany) in September 2008. Various regional field experiments have been conducted in the last few years, mostly close to source regions or after short-range transport. Although significant progress has been made in characterising the regional variability of dust properties close to source regions, in particular the mineralogy of iron and the description of particle shape and mixing state, difficulties remain in estimating the range of va…
Land use functions — a multifunctionality approach to assess the impact of land use changes on land use sustainability
2008
Part 5. Regional and local evaluation - 17; International audience; The dramatic changes in land use observed in Europe in the last fifty years have generally resulted in improvement of human welfare and economic development. On the other hand, they have caused serious environmental problems. There is therefore a need for approaches that help to understand in an integrative way the economic, environmental and societal impacts that land use changes have on sustainability. Sustainability Impact Assessment(SIA), which assesses the impact of policies on sustainability, addresses this challenge. SIA partly builds on the concept of the multifunctionality of land which helps to deal with the compl…
Soil as a Support of Biodiversity and Functions
2014
The soil is a major reservoir of biological diversity on our planet. It also shelters numerous biological and ecological processes and therefore contributes to the production of a considerable number of ecosystem services. Among the ecological, social and economic services identified, the role of soil as a reservoir of diversity has now been well established, along with its role in nutrient cycling, supporting primary productivity, pollution removal and storing carbon. Since the development of industrialization, urbanization and agriculture, soils have been subjected to numerous variations in environmental conditions, which have resulted in modifications of the diversity of the indigenous m…
Linking traffic and noise models to explore spatio-temporal distribution of noise pollution: an example in Besançon (France)
2012
International audience; Road transportation is one of the major environmental noise sources in urban areas, which is characterized by an important temporal and spatial variation. Therefore, linking mobility and traffic model with noise model each representing spatial and temporal dimensions is a great interest. An integrated and original approach was developed to explore noise pollution in urban areas with a spatiotemporal and prospective point of view. An agent-based Land-Use and Transport Integrated (LUTI) model - MobiSim- was used to assess traffic modulation by simulating hourly flows and mobility. Individual choices of agents (representing the city's inhabitants) were transformed to fl…
