Wine Quality Perception: A Sensory Point of View
2016
Wine is a complex product, which had moved from a nutritional food to a hedonic beverage in consumer representation. This fact has increased the demand of quality products in the market. In this context, it is of high interest for wine producers to understand the underlying indicators of consumers’ quality perception as well as the relative importance they attach to these cues when inferring quality in wine to reach the alignment of consumers’ expectations, needs and wants. This chapter is aimed at giving an overview of the current state of knowledge of the indicators of wine quality perception from a sensory point of view. For this purpose, the factors driving perceived quality of wine as …

Mild Dissonance Preferred Over Consonance in Single Chord Perception
2016
Previous research on harmony perception has mainly been concerned with horizontal aspects of harmony, turning less attention to how listeners perceive psychoacoustic qualities and emotions in single isolated chords. A recent study found mild dissonances to be more preferred than consonances in single chord perception, although the authors did not systematically vary register and consonance in their study; these omissions were explored here. An online empirical experiment was conducted where participants ( N = 410) evaluated chords on the dimensions of Valence, Tension, Energy, Consonance, and Preference; 15 different chords were played with piano timbre across two octaves. The results sugg…
Personality and musical preference using social-tagging in excerpt-selection.
2017
Music preference has been related to individual differences like social identity, cognitive style, and personality, but quantifying music preference can be a challenge. Self-report measures may be too presumptive of shared genre definitions between listeners, while listener ratings of expert-selected music may fail to reflect typical listeners’ genre boundaries. The current study aims to address this by using a social-tagging approach to select music for studying preference. In this study, 2,407 tracks were collected and subsampled from the Last.fm social-tagging service and the EchoNest platform based on attributes such as genre, tempo, and danceability. The set was further subsampled acco…
Modern Tendencies in Changing the Consumers’ Preferences
2014
Abstract In the middle of globalization era, when consumers have at their disposal more and more prosperous livelihood, when technology is more and more present, when everyone look for the newest and the most modern thing, food sector represents an exception. They try to establish links which go beyond the product itself and pay a special attention to the story behind the product. They want to know about the production site, the origin of ingredients, the persons involved in the production process. This is why the current consumers are looking for unique, sensorial experiences which, according to them, can be found only in original, simple, traditional products. The simplicity and authentic…
Revisiting the didactic triangle: from the particular to the general
2012
Published version of an article in the journal: ZDM. Also available from the publisher at: http://www.springerlink.com/content/61p78l089tnx8rn5/ The basic notion of a didactic triangle is explained with historical annotations on its origins and subsequent theorization in the literature. Instances of its application to classroom environments to demonstrate its representational capabilities are presented. Generalizations of the triangle are proposed that integrate the role of technology, the researcher in mathematics teaching developmental research, and mediating complexes in the student–teacher–content interfaces. Further, the use of the didactic triangle as a heuristic device is also discus…
Association of burning mouth syndrome with xerostomia and medicines
2005
Objetivo: Identificar factores de riesgo para el síndrome de boca ardiente (SBA) a través de estudio de casos y controles. Material y métodos: Se realizó análisis cuantitativo del flujo salival total en reposo y estimulado; se registraron la xerostomía subjetiva, el consumo de medicamentos y los estados psicológicos de ansiedad y depresión en 40 pacientes con SBA y 40 controles. Resultados: El análisis ANOVA mostró diferencias significativas en las medias del número de medicamentos/día, número de medicamentos xerostomizantes/día, xerostomía subjetiva, ansiedad y depresión, entre los grupos estudiados. No se observaron diferencias significativas en las tasas de flujo salival en reposo y esti…
Data from: How to fight multiple enemies: target-specific chemical defences in an aposematic moth
2017
Animals have evolved different defensive strategies to survive predation, among which chemical defences are particularly widespread and diverse. Here we investigate the function of chemical defence diversity, hypothesising that such diversity has evolved as a response to multiple enemies. The aposematic wood tiger moth (Arctia plantaginis) displays conspicuous hindwing colouration and secretes two distinct defensive fluids, from their thoracic glands and abdomen. We presented fluids from lab-reared moths to two biologically relevant predators, birds and ants, and measured their reaction in controlled bioassays (no information on colour was provided). We found that defensive fluids are targe…
Data from: Dynamic transmission, host quality and population structure in a multi-host parasite of bumble bees
2012
The evolutionary ecology of multi-host parasites is predicted to depend upon patterns of host quality and the dynamics of transmission networks. Depending upon the differences in host quality and transmission asymmetries, as well as the balance between intra- and inter-specific transmission, the evolution of specialist or generalist strategies is predicted. Using a trypanosome parasite of bumble bees we ask how host quality and transmission networks relate to parasite population structure across host species, and thus the potential for the evolution of specialist strains adapted to different host species. Host species differed in quality, with parasite growth varying across host species. Hi…
Data from: Multi-modal defenses in aphids offer redundant protection and increased costs likely impeding a protective mutualism
2018
1.The pea aphid, Acyrthosiphon pisum, maintains extreme variation in resistance to its most common parasitoid wasp enemy, Aphidius ervi, which is sourced from two known mechanisms: protective bacterial symbionts, most commonly Hamiltonella defensa, or endogenously encoded defenses. We have recently found that individual aphids may employ each defense individually, occasionally both defenses together, or neither. 2.In field populations, Hamiltonella-infected aphids are found at low to moderate frequencies and while less is known about the frequency of resistant genotypes, they show up less often than susceptible genotypes in field collections. To better understand these patterns, we sought t…
