The wine hedonic price models in the "Old and New World": : state of the art

The basic hedonic hypothesis is that goods are valued for their utility-bearing characteristics and not for the good itself. Each attribute can be evaluated by consumers when making a purchasing decision and an implicit price can be identified for each of them. Thus, the observed price of a certain good can be analyzed as the sum of the implicit prices paid for each quality attribute. Literature has reported hedonic models estimates in the case of wines, which are excellent examples of differentiated goods worldwide.The impact of different wine attributes (intrinsic or extrinsic) on consumers’ willingness to pay has been analyzed with dissimilar results. Wines coming from "New World" producers seem to be appreciated for different attributes than wines produced in the "Old World". Moreover, "Old and New World" consumers seem to value differently the wine’s characteristics. To our knowledge, no cross country analysis has been done dealing with "New World" wines in "Old World" countries, leaving an important gap in understanding underlying attributes influencing buying decisions.

«Si el hombre careciera de oído…», según Bernardo Silvestre

Durante la primera mitad del siglo XII cobró vigencia en Chartres una escuela de pensamiento filosófico-teológico caracterizada, en buena medida, por el afán de explicación del Génesis mediante el Comentario de Calcidio al Timeo de Platón. La Cosmografía de Bernardo Silvestre, dedicada a Teodorico de Chartres, permanece en las proximidades del interés cientificista y argumentativo propio de esta escuela, pero está formulada en términos literarios, en parte en prosa y en parte en verso. Dividida en dos grandes secciones: ‘Macrocosmos’ y ‘Microcosmos’, se cierra con la descripción de la naturaleza humana y su funcionamiento operativo en los procesos vitales y gnoseológicos. Los sentidos de que goza el hombre, asentados en la cabeza, son considerados instrumentos al servicio del intelecto que juzga. Ellos provienen de una única fuente pero desarrollan de diversas maneras sus operaciones. Si faltaran, no habría ni enseñanza de las letras ni sabiduría.

Selenized garlic: a future prospect or already a current functional food?

In the last years, functional foods have awakened consumer, scientific and business interest. A commonly found vegetable in such kind of foods includes garlic (Allium sativum). By its ability for selenium (Se) bio-accumulation, garlic can turn into an attractive option of selenized food. Selenium is an essential micronutrient for many organisms including plants, animals, and humans. It is an important trace element due to its antioxidant properties and plays a main role in prevention of cancer and cardiovascular diseases. Nowadays, there is an increasing interest in the study of Se speciation due to the different roles that each species manifests in toxicological and nutrition fields. However, Se exhibits a narrow interval between toxicity and essentiality, which is puzzling toxicologists and alarming nutritionists and legislators. In the present review, an overview on the development of selenized garlic studies and its potential implementation in Argentine production is exposed. The development of novel foods with added value such us selenized garlic could be an attractive alternative for local market. Moreover, it becomes a good offering for factory owners, considering that Mendoza represents about 85% of total garlic production in the country.
