Active Learning on Trust and Reciprocity for Undergraduates
2019
We propose a teaching activity aimed at promoting social values, such as trust and reciprocity, among undergraduate students in economics and related degrees. We present our pilot experience of what we call RED&ndash
Assortment, but not knowledge of assortment, affects cooperation and individual success in human groups
2017
The success or failure of human collective action often depends on the cooperation tendencies of individuals in groups, and on the information that individuals have about each other's cooperativeness. However, it is unclear whether these two factors have an interactive effect on cooperation dynamics. Using a decision-making experiment, we confirm that groups comprising individuals with higher cooperation tendencies cooperate at a higher level than groups comprising individuals with low cooperation tendencies. Moreover, assorting individuals with similar cooperation tendency together affected behaviour so that the most cooperative individuals tended to cooperate more and the least cooperativ…
Multisensory perception of dietary faty-acids in Drosophila.
2012
International audience; Fatty-acids (FAs) are crucial for animal survival and reproduction. However, our knowledge of the mechanisms underlying the perception and preference of dietary FA is limited, particularly in invertebrates. We obtained behavioral data with wild-type Drosophila melanogaster larvae and adults showing a clear preference to some of the FAs tested (C14:0, C16:0, C18:0, C18:1, C18:2, C18:3). These data, based on tests involving both individuals and groups, showed that larvae prefer desaturated FAs whereas adults prefer saturated FAs. Moreover, we found that larval and adult responses relied on olfaction and taste modalities, and maybe also on mechanoperception [1]. We will…
Orosensory Perception of Dietary Lipids in Mammals
2008
Obesity constitutes a major public health problem for the twenty-first century, with its epidemic spread worldwide, particularly in children. The overconsumption of fatty foods greatly contributes to this phenomenon. Rodents and humans display a spontaneous preference for lipid-rich foods. However, the molecular mechanisms underlying this pattern of eating behaviour in mammals remain unclear. The orosensory perception of dietary lipids was long thought to involve only textural and olfactory cues. Recent findings challenge this limited viewpoint, strongly suggesting that the sense of taste also plays a significant role in dietary lipid perception and might therefore be involved in the prefer…
What do we learn from comparing hedonic scores and willingness to pay data? [O8.2]
2010
Hedonic measurements are generally conducted in a blind condition and thus evaluate consumer reactions to the sensory characteristics of the products whereas auctions are generally conducted to determine consumer valuation of extrinsic characteristics. In the last 10 years these two approaches were combined to reveal consumer preferences. Thus, tasting was introduced in the auction procedures. However, only two papers reported a comparison of these two approaches (Lange et al., 2002 with a between-subject design and Noussair et al., 2004 with a within-subject design). The aim of this paper is to present such a comparison on four data sets collected in our laboratory for different food produ…
Exploring individual preferences for periurban landscapes
2015
International audience; Landscape aesthetic quality has recently become an important dimension of land use policies since it is likely to play a role in human well-being. Several scientific studies have shown that landscape is a significant component of residential satisfaction of inhabitants in urban and suburban areas (Hur & Nasar, 2010; Kweon et al., 2010). Although neglected by land-use planning for decades (Gallent et al., 2004), urban fringes are particularly interesting for analyzing landscape changes. These spaces where town meets countryside (Scott et al., 2013) are indeed particularly concerned with urban sprawl that occurs in all European cities from 1960s (EEA, 2006). Such chang…
Efectos de las consultas boca a boca en redes sociales en la compra de cosméticos en Ecuador.
2022
Las redes sociales han reestructurado el paradigma de la comunicación en el marketing. Investigaciones recientes demuestran que la conducta de consultar reseñas está adquiriendo un rol fundamental en la decisión de compra de los consumidores. En este contexto, el presente estudio desarrolló un marco de investigación para determinar la cadena de relación entre influencia social, credibilidad percibida del boca a boca, adopción del boca a boca e intención de compra aplicada a la industria cosmética del Ecuador. A través de una muestra de 406 consumidores y la aplicación del método de análisis de ecuaciones estructurales, los resultados evidencian el vínculo existente entre las variables plant…
Player perceptions of informal learning in non-educational games
2022
The potential of non-educational games in learning is well-established, but there have been relatively few empirical studies attempting to explore the kinds of informal learning take place in non-educational games outside of formal education. Simultaneously, student motivation is known to have a connection to learning outcomes, but there is a lack of research on the relationship between gaming motivations and informal learning in games. This paper aims to fill the gap in research by, firstly, forming an empirically-based understanding of what players perceive they are learning from playing non-educational games, and secondly, exploring the potential connections of self-articulated learning …
Role of the nNOS gene in ethanol-induced conditioned place preference in mice
2009
Nitric oxide (NO) produced by neuronal nitric oxide synthase (nNOS) has a role in synaptic plasticity, and evidence suggests its role in a range of effects produced by alcohol in the central nervous system. The aim of the current study was to investigate the role of the nNOS gene in the development of ethanol-induced conditioned place preference (CPP) in mice. The CPP paradigm is designed to investigate the reinforcing properties of drugs of abuse and the development of maladaptive behaviors, such as conditioned response to drug-associated stimuli, following repeated drug exposure. Adult male and female wild type (WT) and nNOS knockout (KO) mice on a mixed B6; 129S genetic background were t…
On Using Decision Maker Preferences with ParEGO
2017
In this paper, an interactive version of the ParEGO algorithm is introduced for identifying most preferred solutions for computationally expensive multiobjective optimization problems. It enables a decision maker to guide the search with her preferences and change them in case new insight is gained about the feasibility of the preferences. At each interaction, the decision maker is shown a subset of non-dominated solutions and she is assumed to provide her preferences in the form of preferred ranges for each objective. Internally, the algorithm samples reference points within the hyperbox defined by the preferred ranges in the objective space and uses a DACE model to approximate an achievem…
