A discrete mathematical model for addictive buying: Predicting the affected population evolution

2011

This paper deals with the construction of a discrete mathematical model for addictive buying. Firstly, identifications of consumers buying behavior are performed by using multivariate statistical techniques based on real data bases and sociological approaches. Then the population is divided into appropriate groups according to the level of overbuying and a discrete compartmental model is constructed. The future short term addicted population is computed assuming several future economic scenarios. © 2010 Elsevier Ltd.

Short term association between ozone and mortality: global two stage time series study in 406 locations in 20 countries

2020

Objective To assess short term mortality risks and excess mortality associated with exposure to ozone in several cities worldwide. Design Two stage time series analysis. Setting 406 cities in 20 countries, with overlapping periods between 1985 and 2015, collected from the database of Multi-City Multi-Country Collaborative Research Network. Population Deaths for all causes or for external causes only registered in each city within the study period. Main outcome measures Daily total mortality (all or non-external causes only). Results A total of 45 165 171 deaths were analysed in the 406 cities. On average, a 10 µg/m3 increase in ozone during the current and previous day was associated with a…

Mortality risk attributable to wildfire-related PM2·5 pollution: a global time series study in 749 locations

2021

Summary Background Many regions of the world are now facing more frequent and unprecedentedly large wildfires. However, the association between wildfire-related PM2·5 and mortality has not been well characterised. We aimed to comprehensively assess the association between short-term exposure to wildfire-related PM2·5 and mortality across various regions of the world. Methods For this time series study, data on daily counts of deaths for all causes, cardiovascular causes, and respiratory causes were collected from 749 cities in 43 countries and regions during 2000–16. Daily concentrations of wildfire-related PM2·5 were estimated using the three-dimensional chemical transport model GEOS-Chem …

La consultation psychologique spécialisée pour les sujets souffrant de syndromes psychotraumatiques : premiers éléments d'évaluation

2004

Resume L'objectif de ce travail est d'evaluer les effets d'une prise en charge psychologique specialisee pour des sujets souffrant d'etat de stress post-traumatique. La population est constituee des 20 premiers patients (moyenne d'âge = 43 ans) de cette consultation, victimes de divers evenements traumatiques (8 agressions physiques et 12 accidents). Les criteres retenus dans l'evaluation du changement therapeutique ont ete : a) l'amelioration des symptomes psychotraumatiques (criteres DSM-IV) ; b) l'amelioration de la sante mentale globale ; c) l'estimation du changement par le therapeute et par le patient ; d) la qualite de l'alliance therapeutique. Les sujets ont ete evalues au debut de …

EFFECTS OF CELLULAR SHORT-TERM STARVATION ON CONVENTIONAL CHEMOTHERAPY RESPONSE IN HUMAN CANCER: UNDERSTANDING OF MOLECULAR MECHANISMS AND MICRORNAS …

Background: Short Term Starvation (STS) is a type of dietary restriction able to reduce tumorigenesis and cancer progression but molecular bases of this effect are still unclear. Aim: In vitro analysis of STS effects in presence of chemotherapy and evaluation of microRNAs (miRNAs) involvement. Results: STS affects the expression profiles of miRNAs involved in chemotherapy response leading to cancer cells sensitization and to healthy cells protection.

Explaining corporate short-termism: self-reinforcing processes and biases among investors, the media and corporate managers

Based on the related literature in economics, organizational sociology and the sociology of finance, this article constructs a novel conceptual explanation for corporate short-termism, that is, the ...

Safety assessment of food-contact paper and board using a battery of short-term toxicity tests: European union BIOSAFEPAPER project.

2005

International audience; An European Union (EU)-funded project QLK1-CT-2001-00930 (BIOSAFEPAPER) involves the development, validation and intercalibration of a short-term battery of toxicological tests for the safety assessment of food-contact paper and board. Dissemination of the results to industry, legislators (e.g. DG Consumer Protection, DG Enterprises, DG Research), standardization bodies such as CEN, and consumers will create an agreed risk evaluation procedure. The project involves pre-normative research in order to establish a set of in-vitro cytotoxicity and genotoxicity tests that will be easily adaptable to food-contact fibre-based materials and have endpoints relevant to consume…

Short-Termism: A Step Forward Toward Long-Term Performance or a Dead End

2018

The debate around short-termism and its effects on the economic life, rather negative than positive, is far from ending, having academics, practitioners, and pundits arguing on this topic. The purpose of this paper is to determine if short-termism is part of the process of creating long-term performance (value) in an organization or it is harmful for harnessing performance, by presenting the definitions of the concept, who are the main promoters of short-termism, opinions of both academics and practitioners, and studies and examples that sustain on the one side the fact that short-termism encourages the manipulation of numbers in order to meet quarterly earnings, by cutting investments from…

Convolutional Long Short-Term Memory Network for Multitemporal Cloud Detection Over Landmarks

2019

In this work, we propose to exploit both the temporal and spatial correlations in Earth observation satellite images through deep learning methods. In particular, the combination of a U-Net convolutional neural network together with a convolutional long short-term memory (LSTM) layer is proposed. This model is applied for cloud detection on MSG/SEVIRI image time series over selected landmarks. Implementation details are provided and our proposal is compared against a standard SVM and a U-Net without the convolutional LSTM layer but including temporal information too. Experimental results show that this combination of networks exploits both the spatial and temporal dependence and provides st…

Association between osteocalcin and cognitive performance in healthy older adults.

2016

INTRODUCTION: cognitive deterioration and reductions of bone health coincide with increasing age. We examine the relationship between bone composition and plasma markers of bone remodelling with measures of cognitive performance in healthy adults.METHODS: this cross-sectional study included 225 old (52% women, mean age: 74.4 ± 3.3 years) and 134 young (52% women, mean age: 23.4 ± 2.7 years) adult participants from the MyoAge project. Whole body bone mineral density was measured by dual-energy X-ray absorptiometry. Blood analyses included a panel of bone-related peptides (dickkopf-1, osteoprotegerin, osteocalcin (OC), osteopontin, sclerostin, parathyroid hormone and fibroblast growth factor …
