Pisco is a brandy made from selected grapes, restricted as Appellation of Origin (AO) in 1931 in Chile by executive order number 181 of May 15, and also legally protected by Peru in 1991 by executive resolution of December 12 and executive order 001-91-ICTI/IND of January 16. This AO has given rise to a commercial controversy between producers of both countries, who claim it as their own. This article proposes a new thesis: The AO of pisco is actually bi-national, belonging to Chile as well as to Peru. The reason is that the producers of the two countries contributed to the origin and consolidation of this product. Pisco would not exist without the participation of both of them. Therefore, the two countries have coownership rights since they are co-founders.

Despite the importance of the theory of evolution to scientific knowledge, a number of misconceptions continue to be found among teachers and undergraduate students. The aim of the present study was to describe and characterise knowledge about evolution among 120 freshman undergraduate students of two natural sciences programmes (environmental biology and veterinary medicine), 80 pre-service science teachers (elementary and biology) and 45 in-service teachers (elementary and biology high school) in Santiago, Chile. The research was carried out based on an eight-question questionnaire about evolution acceptance and understanding. The instrument included seven Likert-scale questions and one open-ended question. An analysis of the data revealed that more than 70% of teachers (pre-service and in-service) and undergraduate students recognised the theory of evolution as established scientific knowledge. When participants discussed the mechanism of evolution in the open-ended question, the most prevalent responses from students and teachers (33%) explained evolution as need-driven changes for survival purposes. Only 13% of the responses could be considered Darwinian, and 10% of responses included more than one view of evolution. The Darwinian responses generally included three important aspects: variation, inheritance and differential reproduction. The implications for biology teacher education are also discussed in this study. © 2014 Society of Biology.

The synergism effects by hydrogen spillover on MD//Re stacked bed systems and MD (MD = Mn/γ-Al2O 3, Fe/γ-Al2O3, Co/γ-Al 2O3, Ni/γ-Al2O3, Cu/γ-Al2O3 or Zn/γ-Al2O 3) on two real diesel feeds with different sulphur contents, have been studied. The total sulphur content and the concentration of six refractory molecules present in the feeds were determinated. The dependence of the synergism with the position of the MD in the periodic table describes a volcano curve with a maximum in Co//Re and Ni//Re pairs. This behavior was observed with both feed and with these six refractory molecules. Furthermore, the activity on Co//Mo, Co//W and Co//Re stacked bed systems of 4-MDBT and 4,6-DMDBT was studied. Results show that spillover factor is higher in 4,6-DMDBT than 4-MDBT, suggesting that Hso can play an important role in improving current state of the art catalysts with respect to the elimination of refractory sulphur molecules.

The present study illustrates the traditional Pome (apple, pear and quince) fruit varieties grown in Chile and Cuyo between 1700 and 1850. The data of the study were obtained from notary and justice archives of Chile, San Juan and Mendoza. Eleven varieties of pear, seven of apple and two varieties of quince were identified. Also, some correspondence with the Muslim fruit culture of al-Andalus in Spain was detected.
The transformation of the labor markets: Telework and its scope in the case of Santiago, Chile [La transformación de los mercados laborales: El teletrabajo y sus alcances para el caso de Santiago, Chile]

During the transition from the 20 th century to the 21 st century the social institution of labor market has experimented important modifications in urban spaces as a consequence of the transformations occurred in different aspects of social life. Teleworking is a phenomenon that has developed during the second half of the twentieth century and has impacted the spatial organization of the urban labor markets. This study contains a discussion of theoretical and practical aspects of telework that are important for geographical research. In this context, urban mobility produced by home place-workplace interaction is an essential fact for the analysis; nonetheless technological base is added because it supports the different teleworking forms and the changes in the work organization patterns. An evaluation of advantages and disadvantages on the implementation of teleworking is made as well as a proposal for lines and areas of possible investigations with a geographical point of view.
