Canción popular, nacionalismo, consumo y política en Chile entre los años 40 y 60

Popular urban music is a typically modern cultural event. Its production, distribution and consumption occurred during the process of urbanization of Chile and in a period of growing availability of technological resources. The broadcasting by the mass media allowed popular urban music to reach a larger audience than the local public. Therefore it did not take long time for popular urban music to become a means of cultural homogenization within the parameters of the market system of production and distribution of music, in Chile. This article aims to map the connections between folk music and popular music, with the formation and consolidation of a consumer market for music in Chile. Besides it considers the use of popular music in the forfties and the sixties as a political tool by different groups of the Chilean society, during a time when arts were considered within the controversies about the national identity that arose in different Latin American countries.

Collaborative language learning in Teletandem: a resource for pre-service teacher education

This article presents some of the results of a qualitative research project about the influences of the pedagogic strategies used by a mediator (graduate student in applied linguistics) in the supervision process of a Teletandem partner (undergraduate student in languages) on her pedagogical practice. It was done within the project Teletandem Brazil: foreign language for all. Based on the reflective teaching paradigm and collaborative language learning, with special emphasis on tandem learning, we analyzed the contributions of the collaborative relationship established between the graduate student and the student-teacher in her first teaching experience. The results bring about implications for the field of language teacher education in a perspective of education within practice, evidencing the experience of collaborative learning in teletandem as an opportunity for reflective teacher education of pre-service teachers.

A NEW SPECIES OF CATHOROPS (SILURIFORMES; ARIIDAE) FROM MESOAMERICA, WITH REDESCRIPTION OF FOUR SPECIES FROM THE EASTERN PACIFIC

The great similarities in the external morphologies and the lack of knowledge on ontogenetic and intersexual differences of species in the ariid genus Cathorops Jordan and Gilbert, 1882, has led to an abundance of misidentifications, causing great nomenclatural instability. Accordingly, the taxonomic statuses of the Cathorops species described from Eastern Pacific have remained controversial in the literature, even in recent studies. Here, we describe Cathorops raredonae, a new species from Mesoamerica (Mexico to El Salvador) and redescribe (in Cathorops) Tachysurus liropus Bristol, 1897, and Arius taylori Hildebrand, 1925, often listed as junior synonyms of Cathorops fuerthii (Steindachner, 1877) and Cathorops steindachneri (Gilbert and Starks, 1904), respectively, or treated as species inquirendae in Cathorops. We also redescribe and redefine the circumscriptions of C. fuerthii and C. steindachneri. Finally, we summarize current statuses of nominal species of Cathorops from the Eastern Pacific and provide an artificial key to identify the valid Pacific species.

The Ecological Basis for Biogeographic Classification: an Example in Orchid Bees (Apidae: Euglossini)

Biogeography has been difficult to apply as a methodological approach because organismic biology is incomplete at levels where the process of formulating comparisons and analogies is complex. The study of insect biogeography became necessary because insects possess numerous evolutionary traits and play an important role as pollinators. Among insects, the euglossine bees, or orchid bees, attract interest because the study of their biology allows us to explain important steps in the evolution of social behavior and many other adaptive tradeoffs. We analyzed the distribution of morphological characteristics in Colombian orchid bees from an ecological perspective. The aim of this study was to observe the distribution of these attributes on a regional basis. Data corresponding to Colombian euglossine species were ordered with a correspondence analysis and with subsequent hierarchical clustering. Later, and based on community proprieties, we compared the resulting hierarchical model with the collection localities to seek to identify a biogeographic classification pattern. From this analysis, we derived a model that classifies the territory of Colombia into 11 biogeographic units or natural clusters. Ecological assumptions in concordance with the derived classification levels suggest that species characteristics associated with flight performance, nectar uptake, and social behavior are the factors that served to produce the current geographical structure.

Reliability and validity of spirituality questionnaire by Parsian and Dunning in the Spanish version

The aim of this methodological study was to translate, culturally adapt and assess the internal consistency and validity of the Spanish version of the "Spirituality Questionnaire". The sample comprised 204 young people between 18 and 25 years of age from two universities in Bogota. Cronbach's Alpha was used for reliability, while groups of experts and young people were used for construct validity. The reliability score of the total instrument was 0.88. The overall index of content validity corresponded to 0.90. Exploratory factor analysis showed that four factors explain 52.60% of the variance. The originally proposed theoretical model was confirmed and, in two dimensions, a different structure was proposed. In conclusion, the instrument "Spirituality Questionnaire" by Parsian and Dunning is reliable and valid in the Spanish version.

Weibull and generalised exponential overdispersion models with an application to ozone air pollution

We consider the problem of estimating the mean and variance of the time between occurrences of an event of interest (inter-occurrences times) where some forms of dependence between two consecutive time intervals are allowed. Two basic density functions are taken into account. They are the Weibull and the generalised exponential density functions. In order to capture the dependence between two consecutive inter-occurrences times, we assume that either the shape and/or the scale parameters of the two density functions are given by auto-regressive models. The expressions for the mean and variance of the inter-occurrences times are presented. The models are applied to the ozone data from two regions of Mexico City. The estimation of the parameters is performed using a Bayesian point of view via Markov chain Monte Carlo (MCMC) methods.

Relationship between body size and flying-related structures in Neotropical social wasps (Polistinae, Vespidae, Hymenoptera)

Body size influences wing shape and associated muscles in flying animals which is a conspicuous phenomenon in insects, given their wide range in body size. Despite the significance of this, to date, no detailed study has been conducted across a group of species with similar biology allowing a look at specific relationship between body size and flying structures. Neotropical social vespids are a model group to study this problem as they are strong predators that rely heavily on flight while exhibiting a wide range in body size. In this paper we describe the variation in both wing shape, as wing planform, and mesosoma muscle size along the body size gradient of the Neotropical social wasps and discuss the potential factors affecting these changes. Analyses of 56 species were conducted using geometric morphometrics for the wings and lineal morphometrics for the body; independent contrast method regressions were used to correct for the phylogenetic effect. Smaller vespid species exhibit rounded wings, veins that are more concentrated in the proximal region, larger stigmata and the mesosoma is proportionally larger than in larger species. Meanwhile, larger species have more elongated wings, more distally extended venation, smaller stigmata and a proportionally smaller mesosoma. The differences in wing shape and other traits could be related to differences in flight demands caused by smaller and larger body sizes. Species around the extremes of body size distribution may invest more in flight muscle mass than species of intermediate sizes.

Comparative study and characterization of starches isolated from unconventional tuber sources

Some properties of canna (Canna indica L.) and bore (Alocasia macrorrhiza) starches were evaluated and compared using cassava starch (Manihot esculenta Crantz) as a reference. Proximate analysis, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and viscosity measurements were performed. Canna and bore starches showed a similar degree of purity as that of the cassava starch. Canna starch exhibited higher thermal stability and viscosity of solution values than those of bore and cassava starches. XRD spectra showed that canna starch crystallizes as a B-type structure; however, bore and cassava starches crystallize as an A-type structure. Results proved that canna and bore starches are promising bio(materials), obtained from unconventional sources, to be used for industrial applications, as their physicochemical properties are similar to those of cassava starch, which it is known has potential applications in this area.

El mito vasco

Los mitos son un instrumento esencial para conocer la cultura de un pueblo y sus raíces porque nos permiten observar el mundo a través de la perspectiva singular de una determinada comunidad. Por ende, los mitos son vestigios de la visión común del mundo de un pueblo y de sus tradiciones y representan un instrumento para reconstruir la identidad social y cultural en el presente. Los mitos se emplean para revitalizar, subrayar y legitimizar la visión común que una determinada comunidad tiene y desempeñan, de este modo, un papel político. Los mitos vascos, en concreto, son esenciales y reflejan la necesidad del pueblo vasco de explicar el mundo y sus fenómenos sin embellecimientos superfluos. Los mitos vascos por excelencia son el mito de Mari, la divinidad-reina que representa un símbolo de fertilidad y el mito del Basajaun y Samartiniko, que intenta explicar el progreso derivado de la agricultura y de la industria. El culto de la etxe y los rituales que este culto implica representan un verdadero mito con sus propias divinidades. Por último, el euskera se presenta como el mito y el misterio más complejo de los euskaldunes. Todos estos relatos folclóricos y estas leyendas contribuyen a la creación de un único macromito: el mito vasco que se ha empleado en la sociedad contemporánea vasca para consolidar la identidad nacional y la unicidad de esta comunidad y para definir lo que significa realmente ser vascos.
