On saturation and related parameters following Guth's ATD colour-vision model
2001
In this work, we have examined the influence of different parameters both on perceived saturation and saturation discrimination with unrelated colours, on the basis of S. L. Guth's CA90 colour-vision model and its subsequent modifications. Our analysis of perceived saturation covered (1) spectral saturation functions at constant luminance, (2) saturation functions in constant colorimetric purity loci, (3) saturation vs. colorimetric purity functions, (4) saturation vs. luminance functions in the 1–1000 td range, and, finally, (5) the equal saturation loci in the xy color diagram. Regarding saturation discrimination, we focused on (1) saturation thresholds from white and from the locus, (2) …
La finance comportementale ou l'émergence d'un nouveau paradigme dominant ?
2005
National audience; Peut-on faire confiance aux cours de Bourse pour prendre des décisions ? De fait c'est la véritable question qui intéresse les gestionnaires et qui justifie que la Revue française de gestion consacre un dossier spécial à la finance comportementale, courant qui a commencé à émerger il y a environ trente ans et qui tend aujourd'hui à se substituer au paradigme dominant dit de l'efficience des marchés. Le paradigme comportemental a reçu une reconnaissance officielle avec l'attribution en 2002, du prix Nobel d'économie, conjointement à Daniel Kahneman et à Vernon Smith.
Ocean acidification affects fish spawning but not paternity at CO2 seeps
2016
Fish exhibit impaired sensory function and altered behaviour at levels of ocean acidification expected to occur owing to anthropogenic carbon dioxide emissions during this century. We provide the first evidence of the effects of ocean acidification on reproductive behaviour of fish in the wild. Satellite and sneaker male ocellated wrasse (Symphodus ocellatus) compete to fertilize eggs guarded by dominant nesting males. Key mating behaviours such as dominant male courtship and nest defence did not differ between sites with ambient versus elevated CO2 concentrations. Dominant males did, however, experience significantly lower rates of pair spawning at elevated CO2 levels. Despite the higher r…

Service-Dominant Logic and Value in Tourism Management: A Qualitative Study within Spanish Hotels Managers
2013
<p><em>With the award-winning article of Vargo and Lusch (2004), a new concept was introduced, called Service-Dominant logic (S-D logic). This paper aims to apply S-D logic to the tourism sector by determining </em><em>if this new approach, by means of the importance of value co-creation, can affect the perceptions of value in the mind of the consumer and, thus, be used as a source of competitive advantage if adopted by tourism service providers. In this paper a conceptual framework is established through a literature review on both S-D logic and value in tourism. After a review of both topics, links between them are conceptually explored. With empirical research met…
El management de las conductas socioemocionales. Una aproximación teórica y empírica desde el caso de los agentes de "contact centers"
2020
How is a specific type of emotion-related work conducts formed today? What principles guide these conducts and what effects do they have on those who work? The study of Contact Center agents allows us to understand how a set of personal qualities such as patience and good treatment of others, certain desires and personal impulses or even intimate sensations such as anguish or individual expectations have become managerialized emotions that end up modifying the inner attitudes of these agents. Within this framework, we propose a theoretical approach that integrates the work of Weber, Foucault and Elias, which invites us to reflect on a socio-emotional manner of leading one?s life (Lebensfu?h…
Studying the stability of Solvent Red 19 and 23 as excise duty components under the influence of controlled factors
2020
Abstract In this study, we examine the chemical stability of two disazo dyes, namely Solvent Red 19 and 23 (SR 19 and SR 23), under simulated conditions. Both dyes are considered to be chemically stable under normal exploitation conditions and therefore, are used extensively as excise duty components that enable a rapid visual verification of the tax levels that were imposed on fuel products as well as identifying fuel usage. However, the results from this study confirmed that the colour of the samples that had been fortified with either SR 19 or SR 23 fades under the influence of external conditions such as UV-A irradiation and temperature over time. The UV-A irradiation was the dominant f…
