La expansión del podcast en la radio pública: estudio comparado de Radio Nacional Argentina y Radio Nacional de España (2019)

La radio pública se enfrenta al desafío de seguir cumpliendo su misión de servicio con las reglas y oportunidades que ofrece el entorno digital para innovar en el contenido y en el modo de alcanzar a las nuevas audiencias. El podcast resulta un formato sonoro que se adapta muy bien a estos tiempos de audiencias diversificadas y con intereses específicos. Esta investigación estudia la oferta de podcast de la radio pública de cobertura nacional en Argentina y España, y con ello persigue delimitar su papel en la ampliación del repertorio de contenidos de la radio tradicional en un entorno de crecimiento de la producción y consumo de audio. Se utiliza la metodología del análisis de contenido para describir y comparar la oferta de podcast de LRA1 y Radio 1, las emisoras generalistas de Radio Nacional Argentina y Radio Nacional de España, respectivamente; y así evaluar en qué grado su implantación fortalece su misión de servicio público.Public radio faces the challenge of continuing to fulfill its service mission with the rules and opportunities offered by the digital environment to innovate in contents and audiences. The podcast is a sound format that adapts very well to these times of diversified audiences and with specific interests. This research studies the podcast offer of the national public coverage radio in Argentina and Spain, and with it seeks to define its role in order to expanding the repertoire of traditional radio content in an environment of production and consumption growth of audio. The content analysis methodology is used to describe and compare the podcast offer of LRA1 and Radio 1, the full service stations of Radio Nacional Argentina and Radio Nacional de España, respectively; and thus evaluate to what extent its implementation strengthens its public service mission

Los modos de contar en los programas magacines de la radio argentina: descripción y análisis de los géneros radiofónicos

El presente artículo estudia los modos de contar de los programas magacines de máxima audiencia de la radio argentina. Se analizan los contenidos de los cuatro programas más escuchados y de fuerte competencia entre ellos al inicio de la presente década. Argentina tiene un mercado radiofónico consolidado, con una penetración del 70% y cuyo pico de audiencia o prime time se localiza entre las 10.00 y las 12.00 horas. Mediante el análisis de contenidos de 160 horas de programación de radio se persigue estudiar el uso de los géneros en los programas líderes del prime time de la radio argentina, según sean de información y opinión, ficción y entretenimiento, o participación de la audiencia. A partir de la frecuencia de aparición y la duración, se mostrará la importancia asignada en la OM/AM y la FM a cada uno de los géneros radiofónicos, así como el grado de integración en el discurso de continuidad que caracteriza a los magacines.The study focuses on storytelling techniques applied in prime-time radio magazines in Argentina. The article analyzes the four leading audience programs at the beginning of this decade. Argentina has a concentrated market, radio penetration reaches 70% and prime time is between 10:00 and 12:00 AM. By means of content analysis of 160 hours of radio programming, use of different radio genres is analyzed in a wide range of prime time programs from news and opinion to fiction and entertainment, including audience participation. The comparative study of frequency and length of each genre, in different programs and different broadcast bands, shows the relative importance of each and the level of use along the continuity which define magazine as a radio format

The earliest ostracods: The geological evidence

The oldest assumed ostracods appear in the fossil record from the Tremadocian Paltodus deltifer conodont Biozone. Although geographically widespread these early ostracods have no obvious Cambrian antecedents. Their first appearance at ca. 485 Ma contrasts with molecular evidence that suggests a much earlier (latest Proterozoic or Cambrian) origin for ostracods. Some Cambrian bivalved arthropods such as Altajanella and Vojbokalina, conventionally referred to the Bradoriida, have carapace morphologies that resemble Ordovician palaeocopid ostracods, though such a relationship is unproven without soft part anatomy. Evidence from preserved soft anatomy demonstrates that Bradoriida, such as Kunmingella, and Phosphatocopida, essentially the Cambrian 'ostracod' record of traditional usage, belong outside the Eucrustacea. Early Ordovician ostracods appeared first in shallow marine, oxygenated environments on shelf margins, in a similar setting to other elements of the 'Paleozoic fauna'. Their biodiversity was low (3 named genera and ca. 12 species), though some taxa such as Nanopsis and Eopilla achieved widespread dispersal between major Ordovician palaeocontinents. As bradoriids were largely extinct by the Late Cambrian, ostracods do not appear to have directly competed with them for shallow marine environments. The rapid colonisation of these settings by ostracods may have been facilitated by the available ecospace vacated by Bradoriida

Guidelines for the use and interpretation of assays for monitoring autophagy

In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. A key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process vs. those that measure flux through the autophagy pathway (i.e., the complete process); thus, a block in macroautophagy that results in autophagosome accumulation needs to be differentiated from stimuli that result in increased autophagic activity, defined as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (in most higher eukaryotes and some protists such as Dictyostelium) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the field understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field
