INFORMACIÓN Y EXPOSICIÓN INDIRECTA PARA REDUCIR ESTEREOTIPOS HACIA EL ENVEJECIMIENTO

2016

Abstract.Purpose: The Image that society has about older people has been built on a base of stereotypes, far away from reality. This social image will have a determinant influence on attitudes and behaviors from all those people related with them, including health care professionals. It should be mandatory to eradicate negative stereotypes against aging during university formation, and in this practice get sensitive professionals who will attend people in their final state of life. Method: the treatment “Information plus indirect experience” was set throw the viewing of the short film “Como un Rolling” (Castilla, 2013). This film exposes the concept of active aging, and had the purpose to b…

Impact of the information provided to consumers on their willingness to pay for Champagne : comparison with hedonic scores

2002

International audience; L'étude a été effectuée afin de comparer deux mécanismes destinés à révéler les préférences des consommateurs : une enchère Vickrey qui mesure la disposition à payer, et un test hédonique classique. A travers ces deux méthodes, l'objectif était d'estimer les effets respectifs des caractéristiques sensorielles et de l'information externe sur l'évaluation de cinq champagnes brut non millésimés. Cent-ving-trois consommateurs ont été assignés au hasard aux deux groupes et ont utilisé l'une des méthodes. Quelle que soit la méthode, ils ont évalué les champagnes à l'aveugle, puis sur la base d'une présentation des bouteilles et, enfin, après l'observation de la bouteille e…

Risk tables for discrimination tests

1993

Abstract Duo-trio and triangle test are often used in the food industry for the purpose of declaring two products non-distinguishable. In that situation, it is much more important to control the power of the test rather than the type 1 error risk. This paper makes available by e-mail a SAS ® macro, called BINRISKS, for computing type 1 and type 2 risks for any one-tailed binomial test and for any level of the percentage above chance to be detected. Using this macro, two sets of tables have been compiled. The first table includes for any total number of responses below 50, for any number of correct responses and for three levels of the percentage above chance to be detected, the correspondin…

The MAM-CAP table: A new tool for monitoring panel performances

2014

Abstract Assessor performances in sensory analysis are usually represented by three indicators: repeatability, discrimination and agreement. However, assessors can also differ on the range of their scores, the so-called “scaling effect”. Brockhoff, Schlich, and Skovgaard (2013) proposed the mixed assessor model (MAM) which, as the original assessor model ( Brockhoff & Skovgaard, 1994 ), takes this effect into account, but also allows for the product effect to be tested against a new interaction free of the scaling effect. The present paper proposes a unified system for monitoring assessor and panel performances based on the MAM. In addition to the product effect (tested at panel and individ…

Dynamics of liking for flavoured crackers: Test of predictive value of a boredom test

1998

Abstract The principal aim of this study was to compare two experimental conditions for measuring the effect of repeated consumption on liking: a laboratory boredom test and a home use test. Another goal was to investigate the impact of perceived familiarity, appropriateness and complexity on the dynamics of liking. Two groups of consumers were recruited, one for each condition. Five variants of salty crackers, each with a different flavour, were tested. The laboratory condition did not show any difference in the dynamics of liking among the flavours. The home condition revealed a significant increase in liking for only one flavour. This increase could not be related to the level of complex…

Monod-based ‘single-data’ strategy for biodegradation screening tests

2020

Environmental contextObtaining biodegradation data over time can be difficult, especially when dealing with environmental compartments of increasing complexity. We evaluated the possibility of obtaining a full biodegradation depletion curve from a single biodegradation-time experimental measurement, and found that environmental information related to potential chemical persistence can be derived. The applicability of this ‘single-data’ strategy is illustrated using simulated and experimental data for several compounds. AbstractInformation obtained from biodegradability tests, e.g. half-life (t50) or kinetics parameters, is relevant in environmental risk assessment of new chemicals. In thes…

2020

Background: An adequate level of muscular fitness is related to occupational performance in military personnel, including pilots flying high performance aircraft. The aim of this study was to describe the baseline level and the change in muscular fitness between the first and the second years of the Air Force Academy among fighter pilot cadets. Methods: The muscular strength and endurance test results of 182 male fighter pilot cadets were analyzed during their first year in the Air Force Academy and one year after. Maximal isometric strength tests included trunk flexion, trunk extension and bilateral leg extension tests, whereas muscle endurance was measured with modified a sit-up test and …

Oxidative stability of virgin olive oil: evaluation and prediction with an adaptive neuro-fuzzy inference system (ANFIS).

2019

Background An adaptive neuro-fuzzy inference system (ANFIS) was employed to predict the oxidative stability of virgin olive oil (VOO) during storage as a function of time, storage temperature, total polyphenol, α-tocopherol, fatty acid profile, ultraviolet (UV) extinction coefficient (K268 ), and diacylglycerols (DAGs). Results The mean total quantities of polyphenols and DAGs were 1.1 and 1.9 times lower in VOOs stored at 25 °C than in the initial samples, and the mean total quantities of polyphenols and DAGs were 1.3 and 2.26 times lower in VOOs stored at 37 °C than in the initial samples, respectively. In a single sample, α-tocopherol was reduced by between 0.52 and 0.91 times during sto…

A comparison between nine laboratories performing triangle tests

2012

WOS: 000299451400001; International audience; Fifteen groups of participants in nine laboratories performed triangle tests with two pairs of soft drinks. Groups differed in practice level with triangle tests: eight groups of 60 consumers who were not used to triangle test, three groups of qualified assessors who have already performed a few triangle tests, and four groups of trained assessors with a more extensive practice of triangle tests; qualified and trained groups included 9 or 18 assessors. The soft drinks were made from syrups at two levels of dilution in order to achieve about 55% of correct responses to test for difference and about 40% of correct responses to test for similarity.…

Double validation of translated questionnaires in international studies

2018

Background Study questionnaires developed in one country can be translated and used for similar studies in other countries. The main problem of this process is that people speaking different languages can understand the meaning of some questions differently due to disparate mentalities and backgrounds. To avoid a misunderstanding, to perform correct conclusions in accordance to the mentality of each country, and to permit the comparison of results in different countries, the intellectual validation of questionnaires is widely used. The main problem of such a validation is its qualitative nature that can be biased by the subjective approach of the investigator. Therefore, there is a necessit…
