Chaînage de bases de données anonymisées pour les études épidémiologiques multicentriques nationales et internationales : proposition d'un algorithme…

2009

Background: Compiling individual records coming from different sources is very important for multicenter epidemiological studies; however, European directives and other national legislation concerning nominal data processing must be respected. These legal aspects can be satisfied by implementing mechanisms that allow anonymization of patient data (such as hashing techniques). Moreover, for security reasons, official recommendations suggest using different cryptographic keys in combination with a cryptographic hash function for each study. Unfortunately, this type of anonymization procedure is in contradiction with common requirements in public health and biomedical research because it becom…

Impact de la proximité identitaire « publics-musée d'art » sur la fréquentation des lieux culturels : le cas des musées d’art

2017

The value that individuals attach to a cultural object can be explained, among other things, by their identity project of belonging to a group. This thesis proposes new strategic orientations for museums that increase museum attendance, change the relationship of the art museum with the public and attract other individuals.This research allowed the conceptualization of the proximity of the "public-art museum" identity, the confirmation of its dimensions and antecedents, and finally the analysis of the relationship between the "public-art museum" identity proximity and the art museum attendance. Moreover, the development of a "public-art museum" identity proximity scale, offers to broaden th…

In situ structural analysis of SARS-CoV-2 spike reveals flexibility mediated by three hinges

2020

Flexible spikes The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein enables viral entry into host cells by binding to the angiotensin-converting enzyme 2 (ACE2) receptor and is a major target for neutralizing antibodies. About 20 to 40 spikes decorate the surface of virions. Turoňová et al. now show that the spike is flexibly connected to the viral surface by three hinges that are well protected by glycosylation sites. The flexibility imparted by these hinges may explain how multiple spikes act in concert to engage onto the flat surface of a host cell. Science, this issue p. 203

The expected value of the traceability information

2015

Abstract Recent regulations on agri-food traceability prescribe traceability throughout the entire supply chain, in order to ensure consumers’ safety and product quality. This has led producers and retailers to consider the opportunity to improve the firm's reputation and consumer confidence through the implementation of traceability systems designed not only to satisfy the legal requirements, but also to track the quality of the products through the supply chain for optimization purposes. However the actual implementation of such systems depends on the possibility of gathering specific information related to the product quality. Nowadays, innovative and non invasive technologies such as th…

Implications of Theories of Language for Information Systems

1985

This article demonstrates how language views can be adopted into an information systems context. We distinguish here between five language views: denotational, generative, cognitive, behavioristic, and interactionist. These views differ in their assumptions about he origin of linguistic behavior, the primary functions of language, elements of language, and the nature of linguistic knowledge. Information system development approaches can be characterized by their underlying language views. This explains great differences in development methods and research. Thus, language views have implications and should be chosen continency for a given information system context.

Discovery privacy threats via device de-anonymization in LoRaWAN

2021

LoRaWAN (Long Range WAN) is one of the well-known emerging technologies for the Internet of Things (IoT). Many IoT applications involve simple devices that transmit their data toward network gateways or access points that, in their turn, redirect data to application servers. While several security issues have been addressed in the LoRaWAN specification v1.1, there are still some aspects that may undermine privacy and security of the interconnected IoT devices. In this paper, we tackle a privacy aspect related to LoRaWAN device identity. The proposed approach, by monitoring the network traffic in LoRaWAN, is able to derive, in a probabilistic way, the unique identifier of the IoT device from…

A Comparison of Language Identification Approaches on Short, Query-Style Texts

2010

In a multi-language Information Retrieval setting, the knowledge about the language of a user query is important for further processing. Hence, we compare the performance of some typical approaches for language detection on very short, query-style texts. The results show that already for single words an accuracy of more than 80% can be achieved, for slightly longer texts we even observed accuracy values close to 100%.

The case for strategic international alliances to harness nutritional genomics for public and personal health

2005

Nutrigenomics is the study of how constituents of the diet interact with genes, and their products, to alter phenotype and, conversely, how genes and their products metabolise these constituents into nutrients, antinutrients, and bioactive compounds. Results from molecular and genetic epidemiological studies indicate that dietary unbalance can alter gene-nutrient interactions in ways that increase the risk of developing chronic disease. The interplay of human genetic variation and environmental factors will make identifying causative genes and nutrients a formidable, but not intractable, challenge. We provide specific recommendations for how to best meet this challenge and discuss the need …
