[Loyauté des transactions sur un marché relatif aux attributs de croyance : une analyse appliquée aux produits agro-alimentaires]

2001

International audience; Après avoir décliné la typologie des caractéristiques des produits en termes d'attributs de recherche, d'expérience et de croyance, les auteurs soulignent les mécanismes susceptibles d'assurer l'efficacité des transactions marchandes. Afin de cerner les enjeux liés à la loyauté des transactions dans le cas des attributs de croyance, ils montrent à l'aide d'un jeu simple, le caractère crucial des phases de définition, de vérification et de signalement, ces dernières nécessitant généralement l'intervention d'agents extérieurs à la transaction marchande.

Teacher educators' collective professional agency and identity : Transforming marginality to strength

2017

Abstract This study investigated teacher educators' collective professional agency and identity within an identity coaching programme. The participants in the programme were teacher educators from the field of arts and crafts education. Through a shared process involving increased trust and togetherness, the teacher educators became empowered in terms of their collective identity and agency. The study points to the importance of addressing individual narratives and learning pathways in seeking to understand emergent collective agency and identity in professional contexts. Our theoretical contribution includes an advanced understanding of collective identity and agency, and of their close re…

Motivation and Consequences of Internet and Mobile Phone Usage among the Urban Poor in Kampala, Uganda

2015

The Internet and mobile phones are rapidly diffusing throughout communities, and it is important to understand what people are actually doing with their access to these technologies. This study seeks to improve our understanding of the motivational factors and social and economic consequences of such use among the urban poor, which is examined through the Diffusion of Innovations Theory (DoI) and the Capability Approach (CA). The combined theoretical perspective was introduced to explore findings of an explorative case study conducted among the urban poor in Kampala, Uganda, where Internet access was found to be low due to high illiteracy and associated costs. On the other hand, mobile phon…

Sport and Quality of Life

2022

Negli ultimi trent’anni lo sport ha assunto un significato molto rilevante nella vita delle persone e, seppure con notevoli differenze, sia nei paesi a sviluppo economico avanzato, sia in quelli in via di sviluppo. A livello individuale, esso ha costituito un’area di investimento identitario quando ha assunto la forma di sport spettacolo del quale fruire, alimentando la pratica del tifo e il fandom o costituendo il modello di uno stile di vita vincente; ma anche quando ha assunto la forma di pratica del tempo libero attraverso la quale tenersi in forma, facendo crescere, in questo caso, la diffusione di una cultura della salute e del benessere. Si tratta di due modalità di approcciare al co…

Reliability and Validity of The Finnish Version of The Boston Carpal Tunnel Questionnaire among Surgically Treated Carpal Tunnel Syndrome Patients

2019

Background and Aims: The Boston Carpal Tunnel Questionnaire is the most commonly used outcome measure in the assessment of carpal tunnel syndrome. The purpose of this study was to translate the original Boston Carpal Tunnel Questionnaire into Finnish and validate its psychometric properties. Materials and Methods: We translated and culturally adapted the Boston Carpal Tunnel Questionnaire into Finnish. Subsequently, 193 patients completed the Finnish version of the Boston Carpal Tunnel Questionnaire, 6-Item CTS Symptoms Scale, and EuroQol 5 Dimensions 12 months after carpal tunnel release. The Boston Carpal Tunnel Questionnaire was re-administered after a 2-week interval. We calculated cons…

Wireless ATM : handover issues

1998

Basic aspects of cellular systems and the ATM transmission technology are introduced. Wireless ATM is presented as a combination of radio ATM and mobile ATM. Radio ATM is a wireless extension of an ATM connection while mobile ATM contains the necessary extensions to ATM to support mobility. Because the current ATM technology does not support mobility, handover becomes one of the most important research issues for wireless ATM. Wireless ATM handover requirements are thus analysed. A handover solution relying on two inter-related handover protocols is presented and evaluated. Future research is needed to compare this solution with options presented by earlier research and possibly combine the…

Asymmetric Synthesis of Fluorinated Monoterpenic Alkaloid Derivatives from Chiral Fluoroalkyl Aldimines via the Pauson‐Khand Reaction

2020

Pauson–Khand reaction of fluorinated compounds

2020

The Pauson–Khand reaction (PKR) is one of the key methods for the construction of cyclopentenone derivatives, which can in turn undergo diverse chemical transformations to yield more complex biologically active molecules. Despite the increasing availability of fluorinated building blocks and methodologies to incorporate fluorine in compounds with biological interest, there have been few significant advances focused on the fluoro-Pauson–Khand reaction, both in the inter- and intramolecular versions. Furthermore, the use of vinyl fluorides as olefinic counterparts had been completely overlooked. In this review, we collect the advances both on the stoichiometric and catalytic intermolecular an…

Virucidal effect of high power ultrasound combined with a chemical sanitizer containing peroxyacetic acid for water reconditioning in the fresh-cut i…

2015

The use of chlorine-based sanitizers is widespread throughout the fresh produce industry in the process water to maintain microbial safety of produce, avoid cross-contamination and recycle water. In this study, alternative disinfection technologies were investigated due to the negative reports showing chlorine instability in the presence of organic matter and the undesirable by-product residues. Tsunami ® (15.2% peroxyacetic acid and 11.2% hydrogen peroxide) and high-power ultrasound (HPU, 0.56 kW/l, 20 kHz), alone or in combination, were evaluated in lettuce process water analyzing their ability to reduce MNV during either produce washing or water recycling. PAA concentrations of 6.4, 12.8…

Effect of traditional, microwave and industrial cooking on inositol phosphate content in beans, chickpeas and lentils

2003

An high-performance liquid chromatography method for determining inositol phosphate fractions was adapted to legumes. The validity of the method was assessed by estimating the following analytical parameters: linearity (linear response between 125 and 5000 microg inositol hexaphosphate (IP(6))/ml); instrumental precision and method precision (relative standard deviation, %) were 1.9% (IP(6)) for instrumental, and 2.5% (IP(6)) and 8.2% (IP(5)) for method precision. An accuracy was estimated by percentage recovery (72 +/- 3%). The application of this method to raw, conventional, microwave-cooked and ready-to-eat beans, chickpeas and lentils gave IP(6) contents ranging from 0.63 g/100 g dry ma…
