Levels of ochratoxin A in wheat and maize bread from the central zone of Portugal.
2007
Ochratoxigenic fungi are natural contaminants of cereal and the produced toxins are harmful to humans and animals. Ochratoxin A (OTA) is among the most important mycotoxins, and the International Agency for Research on Cancer (IARC) classifies it as possibly carcinogenic to humans (group 2B). A total of 61 samples of bread from the central zone of Portugal were analysed for OTA by liquid chromatography (LC) with fluorescence detection (FD). For confirmation two procedures were applied, methyl ester derivatization with boron trifluoride-methanol and liquid chromatography/electrospray ionization tandem mass spectrometry (LC/ESI/MS/MS). As far as we know, this is the first report where on-line…
Habituation and adaptation to odors in humans
2017
indexation en cours; Habituation, or decreased behavioral response, to odors is created by repeated exposure and several detailed characteristics, whereas adaptation relates to the neural processes that constitute this decrease in a behavioral response. As with all senses, the olfactory system continually encounters an enormous variety of odorants which is why mechanisms must exist to segment them and respond to changes. Although most olfactory habitation studies have focused on animal models, this non-systematic review provides an overview of olfactory habituation and adaptation in humans, and techniques that have been used to measure them. Thus far, psychophysics in combination with moder…
Reklāmas ietekme uz jaunās paaudzes patērētāju uzvedību Uzbekistānā
2022
Pētījuma mērķis ir izpētīt patērētāju uztveri, attieksmi un atbildi uz tiešsaistes reklāmām Uzbekistānā. Lai sasniegtu pētījuma mērķi, tika izstrādāta strukturēta anketa un ar izlases palīdzību tika apkopotas 200 respondentu no Uzbekistānas atbildes. Tika konstatēts, ka tiešsaistes reklāma ir noderīga respondenta atbilstoša lēmuma par pirkumu pieņemšanai, kā arī tiešsaistes reklāma pozitīvi ietekmē patērētāja pirkšanas tendences. Tika noskaidrots, ka reakciju uz tiešsaistes reklāmu spēcīgāk prognozē patērētāja attieksme nekā patērētāju uztvere par reklāmu tiešsaistē. Rezultāti liecina par to, ka uzņēmumiem, kas veicina produktu pārdošanu ar tiešsaistes reklāmām, ir jācenšas sasniegt potenci…
The dynamics of technological substitution: the case of eco-innovation diffusion of surface cleaning products
2016
Some eco-innovations have already reached a mature state, but they diffuse slowly. There is little known about the importance of various factors on the diffusion process of eco-innovations. The aim of this research is to propose a conceptual model for eco-innovation diffusion, where particular case study of eco-innovation – micro-fibre cloth (MFC) for surface cleaning purposes – is given. The work will study the relative importance of various motivations on diffusion processes as well as the influence of information campaigns. This novel methodology has been developed under the system dynamics framework and is coupled with the logistic regression model. Structural validation tests were done…
A genetic algorithm for analyzing choice behavior with mixed decision strategies
2009
In the field of decision-making a fundamental problem is how to uncover people's choice behavior. While choices them- selves are often observable, our underlying decision strategies determining these choices are not entirely understood. Previous research defined a number of decision strategies and conjectured that people do not apply only one strategy but switch strategies during the decision process. To the best of our knowledge, empirical evidence for the latter conjecture is missing. This is why we monitored the purchase decisions 624 consumers shopping online. We study how many of the observed choices can be explained by the existing strategies in their pure form, how many decisions can…
Expectation, liking and purchase behaviour under economical constraint
1998
Abstract A panel of 123 consumers from Dijon and Nantes rated their liking for six orange juices (two pure juices, two juices made with concentrate and two nectars) in a blind condition, and then with information about the type of juice and packaging. Expectations induced by the information were also measured and the effect of this expectation on their evaluations were studied, as well as the role of the price on the purchase behaviour when the consumers were placed in a situation of choice under economical constraint. When discrepancy between blind rating and expectation was large, consumers generally moved their ratings towards expectation when they tasted a product in presence of informa…
AN ORDERED PROBIT MODEL FOR THE ANALYSIS OF OVERALL CUSTOMER SATISFACTION (OCS) REGARDING ORGANIC-FOOD COMSUMPTION
2004
Organic-food consumers and some related issues were investigated in the city of Palermo. Consumers were asked to express their global satisfaction regarding consumption of organic food, as well as some other personal information. A survey was conducted from the four main retail outlets specialized in organic-food by interviewing nearly 200 customers. The data were used to analyse the overall satisfaction of the local organic-food consumer. Furthermore, a “discrete choice” model was run by using the overall customer satisfaction (OCS) derived from the consumption of organic food as a dependent variable. A set of other variables were used as regressors. Model outputs identified the key determ…
Organic consumption and consumer participation in food community networks
2012
Due to improvements in welfare, new food consumption concerns have emerged in Europe. Such concerns go beyond issues related to food safety and market prices. Solidarity Purchasing Groups (GASs) are one way to combine utilitarian and ethical aspects: in these groups the trade in organic products predominates. The aim of GAS groups is to primarily develop a local economy which is both ethical and fair, providing networks of economic solidarity through social relations and economic-territorial districts. This paper sets out to determine the profiles of the consumer groups that constitute GASs in Sicily (southern Italy) in order to search for key elements of the movement in terms of both commu…
Decreasing consumer animosity: The relationship between fast food businesses and social conflicts in Latin America and the Caribbean
2021
Consumer animosity represents discomfort towards foreign goods, services and brands originating in countries with which there is some kind of conflict; in this way, a better understanding of consumer behavior in respect of hostilities between countries is sought. On the other hand, the conflicts in Latin America and the Caribbean are often overlooked in the academic literature, which focuses on studying the major Western economies and the great Asian tigers, given their political, economic and military value; for this reason, consumer animosity studies are mostly conducted in these countries. This study seeks to contribute to the scarce literature on consumer animosity in Latin America, thr…
