A Macroeconomic Estimation of the Education Production Function
2007
07/002; The aim of this paper is to test the existence of an education production function based on data resulting from international surveys of pupil assets. The results of the estimates, using first the total sample, and then making distinctions according to the economic level of the country, show significant differences concerning the relationships between educational inputs and outputs. Thus, inconsistencies found in former analyses in terms of estimating the education production function can partially be explained by the fact that they failed to take into account the economic level of the countries analysed.
Economic crisis and educational crisis : looking ahead
1986
The worldwide economic crisis has now been with us for a good ten years and, for many countries, the end of the tunnel is not yet in sight and is probably a long way off. So what kind of crisis is this, that can continue for so long, given the fact that, etymologically, the term denotes a brief, crucial moment when the outcome of a troubled situation is decided, for better or for worse? Infelicitous as the term commonly used to describe the present state of the world economy may be, it is none the less true that what is designated as a crisis encompasses a historical phase in which economic growth is lower than in the preceding phase and the problems bound up with certain economic trends (i…
Autonomous management of Quality of Service and security in an Internet of Things environment
2019
Nowadays, the Internet of Things (IoT) is becoming important in our daily lives thanks to technological advances. This paradigm aims to improve the quality of human life through automating several tasks. In this context, service level guarantee within IoT environments is a major challenge while considering a massive deployment of IoT applications and services as well as extending their usage to different domains. The IoT service level can be characterized in two parts: Quality of Service (QoS) and security. Moreover, this service level must be managed in an autonomic manner within the IoT environment given the heterogeneity and the size of its infrastructure making it difficult, even imposs…

A number of phonetic and phonological changes have lately been observed in most geographical varieties of British English. This phenomenon seems to have been accelerated by increasing social and geographical mobility in the past decades. Based on a corpus mainly consisting of several hours of spontaneous interaction between a number of native NW Yorkshire speakers divided into different age groups, this research identifies and analyses several segmental and suprasegmental innovations observed in apparent time in a set of accents associated with a circumscribed geographical area. This thesis discusses the motivation behind some of these changes and addresses the question of whether the same …

Formulation, process conditions, and biological evaluation of dairy mixed gels containing fava bean and milk proteins: Effect on protein retention in…
2019
International audience; Food formulation and process conditions can indirectly influence AA digestibility and bioavailability. Here we investigated the effects of formulation and process conditions used in the manufacture of novel blended dairy gels (called "mixed gels" here) containing fava bean (Vicia faba) globular proteins on both protein composition and metabolism when given to young rats. Three mixed dairy gels containing casein micelles and fava bean proteins were produced either by chemical acidification (A) with glucono-δ-lactone (GDL) or by lactic acid fermentation. Fermented gels containing casein and fava bean proteins were produced without (F) or with (FW) whey proteins. The AA…

Geometric quality and appearance of surfaces : local and global approaches
2012
Accounting for customers' perception of manufactured goods has become a major challenge for the industry. This process is to be established from early design to retail. Customers are nowadays more aware and detail oriented about perceived quality of products. This allows one to set not only an estimated price but also the expected quality of the product. Surface appearance analysis has therefore become a key industrial issue. Two approaches are proposed here to formalize the detection methodology and provide objective criteria for experts to evaluate surface anomalies. The first proposed approach is based on surface metrology. It consists in analyzing the measured topologies in order to bin…
Cross-cultural differences in consumer quality perception of rice
2014
International audience; Most aspects of food product quality perception are culture-bound. We present a cross-cultural study aiming at understandinghow consumers from four countries (French, Japanese, Korean and Thai) perceive, describe and appreciate rice and ricequality. Marked differences were found in participants' motivation to consume rice: sensory and commodity in France; sensoryand health in Japan; nutrition and commodity in Thailand; and nutrition, health and safety in Korea. For the description of ricequalities, despite a few cultural differences, especially between Korean and Thai descriptions of white and brown rice samples,similar sensory profiles were obtained in the four coun…
Model and quality assessment of single image dehazing
2016
This thesis is mainly related to color imaging science, involving many disciplines, such as color image enhancement, image formation, color reproduction, optical physics, radiometry, colorimetry, image quality and psychophysics.Dehazing aims at recovering the image information degraded by light scattering, e.g. bad weather. This process is an ill-posed and a challenging problem. Although a variety of approaches have been proposed, there is still room for further improvement and standardization. In this work, we investigate the limitations of haze model in terms of accuracy of color image recovery. We address also the link between the visibility deterioration and the spectral content of the …
