The construction of territoriality implies the participation of diverse agents who take part in society by contributing with different approaches, knowledge and ways of appropriating space. Written press takes a stance acting as a communicator of social, cultural, political and economic processes, being able to become an agent of change in the appropriation and delimitation of space. Ushuaia and Punta Arenas are positioned as two of the five gateways to Antarctica, due to their location and functionality, playing a fundamental role by having the ability to provide different services necessary for governmental and non-governmental activities to be developed in Antarctica. From this perspective, the aim of this contribution is to analyze the place that science and tourism occupy as strategy in the construction of territoriality for these two gateway cities to Antarctica, Ushuaia and Punta Arenas. A qualitative methodology based on the content analysis of documents from mass media corresponding to press genre (national and provincial) from January 1 to December 31, 2019 was implemented. The results reflect the topics of interest of each city, showing coincidences in some cases and differences in others, depending on the priorities assigned by each territory. The work presents the different relationships between the written press and the geographical space, depending on the social groups involved and their interests, as well as according to the scalar level. It also shows that there are various aspects that contribute to the construction of territoriality.

Climate change and evident global warming make climate characterization at a regional scale essential to know the climate of a region, given that its variability could affect the economic activities. In this context, arid areas are relevant because they are vulnerable to climate variability effects. In order to study the climate, it is necessary to have meteorological series for at least 30 years. Sometimes they are scarce or incomplete. For these reasons, numerical climate models emerge as a tool that favors the generation of this information. This study aimed at studying the adjustment between the data of climatic variables obtained from the Renalysis and those observed in situ, considering a climatic (1960-2020) and a seasonal scale. To do that, it was analyzed monthly data series of air temperature, relative humidity, and precipitation measured in situ from nine meteorological stations. Then, we compared them with those acquired from the Reanalysis. Two-time scales of analysis were applied. In a first instance, the data was contrasted and statistically evaluated on a climatic scale, considering 1960-2020 period. Then, seasonal adjustments at the regional scale were studied. As a result, it was obtained that air temperature and precipitation were the variables that presented suitable statistical adjustments in both time scales. Relative humidity did not have significant results. It was shown that it is possible to correct the Reanalysis data for the climatic characterization of Cuyo Region. The information generated represents a solid database for designing a land management plan framed within sustainable development guidelines.

  El marco espacial del presente estudio, fue la cuenca del río Huitzilac, situada geográficamente al suroeste del estado de Puebla, México. En este estudio, se analizan los parámetros morfométricos de la cuenca citada y su red de drenaje, con el fin de comprender su dinámica superficial. Para ello, se utilizaron índices cuantitativos y Sistemas de Información Geográfica (SIG). Se completó la información con trabajo de campo. Los resultados más relevantes muestran que la cuenca posee un área de 615 km2, por lo que se clasifica entre “intermedia a grande”. Los valores de los parámetros de forma, elongación y compacidad, sugieren una forma alargada, con tendencia a una configuración rectangular-oblonga. Es un sistema de quinto orden con patrón de drenaje principalmente de tipo dendrítico-subdendrítico. La curva hipsométrica y el factor de circularidad muestran una etapa de equilibrio relativo o de madurez, implicando un potencial erosivo, principalmente en la parte alta del área de estudio, mismo que no debe subestimarse. En general, las características morfométricas atenúan algún efecto negativo, debido a posibles inundaciones.  

The objective of this investigation is to characterize the frequency, duration and intensity of extreme cold episodes (Period of Very Low Extreme Temperatures -PVLET-, Cold Waves –CW- and Frost Days –FD0-) that occurred in Bahía Blanca and the synoptic situation associated to its development. We observed that most of the PVLET and OC had a three-day duration and occurred in June and July. About its decadic frequency, the 10-year periods 1981-1990 and 1991-2000 had the highest records of the whole period. In 2011-2020 we found the minimum frequency of PVLET and no HW were recorded. About the relationship between intensity and absolute frequency of CW, we verified that when CW where more frequent, its mean decadic intensity was higher. On the synoptic situations, CW were associated with the presence of a high pressure system in the center of the country, which defines the dominance of cold, dry air and clear skies. Winter frosts were the most intense and frequent in all decades and late frosts were more frequent and intense than the first ones. In the highest intensity range analyzed there was only a record of occurrence for winters and only in the first three decades. During 2011-2020 we observed a decrease in the intensity of first frosts, and late frosts showed an increase in frequency of occurrence and intensity.

En los últimos años el concepto de patrimonio, complejo y polisémico ha sufrido una evolución teórica y conceptual. Esto se traduce en la práctica a través de disímiles perspectivas de abordaje y análisis que difieren en la consideración de la temporalidad, en los actores sociales involucrados y en la escala geográfica. Una de ellas, la perspectiva crítica, entiende al patrimonio como los procesos o mecanismos elaborados socialmente, y en los cuales se prioriza el rol y decisiones de los actores oficiales o hegemónicos. Este artículo focaliza en esta visión y la aplica a un caso de estudio: el Área Metropolitana de Mendoza. En este sentido, el objetivo busca identificar la tipología y distribución de los bienes patrimoniales de los departamentos que componen el área de estudio desde esta perspectiva para, posteriormente, plantear reflexiones vinculadas con la consideración del paisaje como patrimonio. La metodología combina aspectos cualitativos y cuantitativos encadenando los resultados de cada etapa. Finalmente, se plantean propuestas a considerar en futuras investigaciones y casos de estudio.

The independence of journalism and pluralism are fundamental components of freedom of expression, frequently invoked by the media to defend or criticize proposals for media regulation. However, its media coverage has received little attention from public policy studies. In order to account for the changes and continuities in the discourse on editorial independence in two communication media, this paper analyzes the evolution of coverage on media regulation in the Argentine newspapers Clarín and Página/12 over four decades. We examined the articles published on media and telecommunications regulation projects (n=140) during the years 1988, 1998, 2008 and 2018. This work contributes to the literature on the links between journalistic ideals and practice, identifying the use of different strategies by newspapers to defend their position throughout the period. In the conclusions, we reflect on the distance between the journalistic ideal and professional practice in a concentrated and polarized media scene.

The article adopts the framework of Lotman’s last cultural semiotics in order to rethink a thorny contemporary issue, that is, the diffused antagonism against science, medicine, and vaccinations during the ongoing COVID-19 pandemics. The article interprets this irrational animadversion as the outcome of a dialectics that stems at least from the origin of modernity, and precisely from the opposition between a semiotic ideology of stillness, regularity, and order, underpinning the genesis of modern science, and an opposed semiotic ideology of motion, irregularity, and chaos, characterizing most of the modern aesthetics of idealism and singularity. After exploring this opposition through a crucial cultural text situated at the beginning of the tension between these two different approaches to meaning and life, the article concludes that modern sciences and medicine should continue searching for regularities in the world and in the body, for the sake of improving the human quality of life, but should also learn from the cultural semiotics of aesthetic ideologies: in times of epistemic incertitude and turmoil, old myths extolling the singularity of the body tend to resurface, jeopardizing the credibility of medicine.

Rescued from oblivion by Internet and neurosciences, telepathy once again raises the issue of thought-transmission. The hypothesis about communication without mediation —to date, never scientifically proven— contradicts the principles of semiotics of culture developed by the Tartu School, namely: the necessity of codes and interpretation; in brief: the inevitability of mediation. With the aim of probing this contradiction, this article shows how the presumed mind-to-mind communication presented itself as the wireless telegraph ghostly double, and secondly as the radio broadcasting double. It concludes that telepathy, epitome of barrier-free communication, can be understood as the symptom of an ancient cultural yearning for a full communion with the Other, mingled with fears to mind intrusion created by mass media and the Consciousness Industry.

This article reflects on the notion of exoticism and considers its possible application to the advertising of watch brands. Based on the contributions of Victor Segalen and Juri Lotman to the understanding of encounters between different cultures, new definitions and a semiotic square of the modes of production of exoticism are introduced. The aim is to provide some useful tools to manage a phenomenon that, although widespread in advertising, is little studied.

The aim of this article is to describe the semiotic mechanisms of the semantic correlations that political communication creates in order to turn them into "political grammars" and, therefore, into "norms". It is therefore a matter of studying the transformation through operations of "synthesis of the heterogeneous" carried out by linking elements of political discourse with others belonging to semantic paradigms that are in principle completely alien to it, with the aim of producing explanatory generalisations of the political world as a whole. Such operations, which begin at the level of texts and end up producing political metasemiotics, are made possible by a specific property of language, namely that of its "elasticity".
