Private label food products: Consumer perception and distribution strategies
2022
Food Products Private Label PL, are foods produced by the food industries on order of food distribution companies. Their characteristic is that they are similar to industrial brands but are marketed under the name of the distribution company. Over time they have spread to countries with high per capita income, so much so that today they have become an established product in the food market. Today the PL makes it possible to overcome the criticalities that small agricultural businesses have, which cannot relate to the large-scale retail trade. The PL allow the survival of the company and the permanence of the man in the rural environment. The aim of this research was to analyze the benefits …
On the influence of context-based complexity on information search patterns: An individual perspective
2014
Although context-based complexity measured as the similarity and conflict across alternatives is dependent on individual preference structures, existing studies investigating the influence of context-based complexity on information search patterns have largely ignored that context-based complexity is user- and preference-dependent. Addressing this research gap, this article elicits the individual preferences of decision makers by using the pairwise-comparison-based preference measurement (PCPM) technique and records individuals' search patterns using eye tracking. Our results show that an increased context-based complexity leads to an increase in information acquisition and the use of a mor…
An adaptive approach to learning the preferences of users in a social network using weak estimators
2012
Published version of an article in the journal: Journal of Information Processing Systems. Also available from the publisher at: http://dx.doi.org/10.3745/JIPS.2012.8.2.191 - Open Access Since a social network by definition is so diverse, the problem of estimating the preferences of its users is becoming increasingly essential for personalized applications, which range from service recommender systems to the targeted advertising of services. However, unlike traditional estimation problems where the underlying target distribution is stationary; estimating a user's interests typically involves non-stationary distributions. The consequent time varying nature of the distribution to be tracked i…
A Projection Pursuit Algorithm for Preference Data
2018
In the framework of preference rankings, the interest can lie in finding which predictors and which interactions are able to explain the observed preference structures. The last years have seen a remarkable owering of works about the use of decision tree for clustering preference vectors. As a matter of fact, decision trees are useful and intuitive, but they are very unstable: small perturbations bring big changes. This is the reason why it could be necessary to use more stable procedures in order to clustering ranking data. In this work, following the idea of Bolton (2003), a Projection Pursuit (PP) clustering algorithm for preference data will be proposed in order to extract useful inform…
Treatment of flying phobia using virtual reality exposure with or without cognitive restructuring: Participant's preferences
2015
This study analyses participants’ preferences regarding two exposure treatment modali- ties for Fear of Flying (FF): virtual reality exposure treatment (VRET) by itself or VRET plus cognitive restructuring (VRET+CR). An alternating treatment conditions design was established and a non-concurrent multiple baseline design across individuals (four participants) was used. Both conditions were equally effective and after the treatment all the participants took a flight. At the end of each session the participants were asked for their opinion on the condition they received. High mean scores were obtained in both conditions; non-significant differences between the two condi- tions were found. When…
Identity, Threat Aversion, and Civil Servants' Policy Preferences: Evidence from in the European Parliament
2017
The accepted and peer reviewed manuscript to the article Distinct policy options are typically characterized by a number of advantages (or ‘opportunities’) and disadvantages (or ‘threats’). The preference for one option over another depends on how individuals within an organization perceive these opportunities and threats. In this article, we argue that individuals' identification with an organization's core aims and objectives constitutes a key determinant of this perception. We propose that stronger identification shifts individuals' attention towards potential threats rather than opportunities in the payoff distribution, encouraging avoidance of negative outcomes. Moreover, we argue that…
Choice alters Drosophila oviposition site preference on menthol
2013
Summary Food choice and preference relies on multiple sensory systems that are under the control of genes and sensory experience. Exposure to specific nutrients and nutrient-related molecules can change food preference in vertebrates and invertebrates. For example, larval exposure of several holometabolous insects to menthol can change their adult response to this molecule. However, studies involving Drosophila melanogaster exposure to menthol produced controversial results due maybe to methodological differences. Here, we compared the oviposition-site preference of wild-type D. melanogaster lines freely or forcibly exposed to menthol-rich food. After 12 generations, oviposition-site prefer…
Heterogeneity in general practitioners’ preferences for quality improvement programs: a choice experiment and policy simulation in France
2016
International audience; Despite increasing popularity, quality improvement programs (QIP) have had modest and variable impacts on enhancing the quality of physician practice. We investigate the heterogeneity of physicians’ preferences as a potential explanation of these mixed results in France, where the national voluntary QIP – the CAPI – has been cancelled due to its unpopularity. We rely on a discrete choice experiment to elicit heterogeneity in physicians’ preferences for the financial and non-financial components of QIP. Using mixed and latent class logit models, results show that the two models should be used in concert to shed light on different aspects of the heterogeneity in prefer…
The Lasting Influences of Early Food-Related Variety Experience: A Longitudinal Study of Vegetable Acceptance from 5 Months to 6 Years in Two Populat…
2016
International audience; Children's vegetable consumption falls below current recommendations, highlighting the need to identify strategies that can successfully promote better acceptance of vegetables. Recently, experimental studies have reported promising interventions that increase acceptance of vegetables. The first, offering infants a high variety of vegetables at weaning, increased acceptance of new foods, including vegetables. The second, offering an initially disliked vegetable at 8 subsequent meals markedly increased acceptance for that vegetable. So far, these effects have been shown to persist for at least several weeks. We now present follow-up data at 15 months, 3 and 6 years ob…
Preferencias implícitas de una muestra española: una técnica novedosa para determinar preferencias raciales
2015
Las preferencias raciales expresadas explícitamente pueden carecer de información que sea completa en su contenido, ya sea porque las personas prefieren no expresar sus actitudes per se o tal vez porque no estén al tanto de ellas. El Implicit Association Test (IAT), desarrollado por Greenwald, Banaji y Nosek, evalúa las preferencias implícitas de las personas a través de una plataforma de internet. Demuestra que cuando una persona expresa una preferencia en particular, es posible que no conciba que esa actitud tenga un componente inconsciente y que pueda modificarla. Se obtuvieron 235 sujetos que respondieron a la prueba de preferencia implícita de raza (negra y blanca), a través del portal…
