Ramiro Guerra: caminante y testigo
No full textABSTRACT Introduction: The article presents an assessment of the figure of Ramiro Guerra y Sánchez given not only by its author but also by valuable intellectuals contemporary with Guerra such as Carlos Rafael Rodríguez, Raúl Roa, Medardo Vitier, Fernando Ortiz, Emilio Roig de Leuchsenring. Methods: In this study about Ramiro Guerra, a distinction of his intellectual productionis made along two main lines: the texts with pedagogical content and critical analysis to Cuban education and the historiographic essay. Results: Specifically, the author pauses in the analysis of two works considered «minor» within his historiographical task: Mudos Testigos (1948) and Por las veredas del Pasado (1957), which demonstrate the valuable contribution of Ramiro Guerra to the social, regional and rural family history in Cuba between the end of the 19.th century and the beginning of the 20.th century. Conclusions: The conclusions are aimed at placing Ramiro Guerra in a very important position within the Cuban intelligentsia of the 20.th century and to understand his validity in Cuban historical studies.RESUMEN: Introducción: En el artículo se presenta una valoración de la figura de Ramiro Guerra y Sánchez dada no solamente por el autor del trabajo sino por valiosos intelectuales contemporáneos con Guerra como Carlos Rafael Rodríguez, Raúl Roa, Medardo Vitier, Fernando Ortiz, Emilio Roig de Leuchsenring. Métodos: En este estudio de Ramiro Guerra se hace una distinción de su producción intelectual en dos grandes líneas: los textos de contenido pedagógico y análisis crítico de la educación cubana y el ensayo historiográfico. Resultados: De manera puntual, el autor se detiene en el análisis de dos obras consideradas «menores» dentro de su faena historiográfica: Mudos testigos (1948) y Por las veredas del pasado (1957), las que demuestran la valiosa contribución de Ramiro Guerra a la historia social, regional y de la familia rural cubana entre finales del siglo XIX e inicios del siglo XX. Conclusiones: Las conclusiones están encaminadas a situar a Ramiro Guerra en un lugar importantísimo dentro de la intelectualidad cubana del siglo XX y a comprender su vigencia en los estudios históricos cubanos

Exploration of biomaterials design space through combinatorial and high-throughput approaches: tyrosine-derived polycarbonates as a case study
No full textThe use of combinatorial and high-throughput approaches in the design and exploration of materials space has been gaining increasing acceptance in recent years. While these methods have been successfully employed in the development of materials for the fields of electronics and optics, only a few examples exist within the field of biomaterials science. While there is a clear need for complex polymer structures that can be tailored for specific applications, most current research is being done on the basis of "trial and error" approaches that simply cannot keep up with the demand for novel technologies.
As part of the work involved in this thesis, the number of viable biomaterial candidates was increased by varying the chemical composition of tyrosine-derived monomers in two positions, namely the backbone and pendent chain. The resulting monomers proved to have different physical and chemical properties, derived from small modifications to their chemical structure.
In order to effectively synthesize several compositions of tailored tyrosine-derived polycarbonates, automated synthetic procedures were created and evaluated in a modern robotic platform. The challenges involved in the automation of polycondensation reactions, such as liquid handling, dropwise addition, and toxic chemical handling, were addressed successfully. A considerable amount of time was saved in comparison to manual methods when generating large polymer libraries.
In order to study structure-property relationships, the mass-per-flexible-bond principle was used to quantitatively explain the large range of glass transitions observed in a library of polymers containing homo-, co-, and terpolymers. Within this context, the information gathered in this thesis is expected to be used as a guideline for the rational design of polymers for specific applications.
The information derived from this work made it possible to ascertain that future research can certainly benefit from the automated parallel synthesis methods developed during it, as well as from the linear relationships found. It is expected for the research done in this thesis to have a definite impact not only on the use of combinatorial and high-throughput approaches in polymer science, but also on the informatics aspect involved.Ph.D.Includes bibliographical references (p. 158-165)by Ramiro Rojas Escontrilla
Capturing and radio ear-tagging neonatal vicuñas
No full textWe used and evaluated the effectiveness of a hand-capture technique to capture and mark neonatal vicuñas (Vicugna vicugna) at San Guillermo National Park, west-central Argentina. We captured and marked 98 neonates during 5-31 January, 2008-2010. Capture success was 92% (106 attempts), with stationary marking teams being 2.5 times as successful in detecting and capturing neonates as mobile ones. Of neonates captured, 99% were 20 minutes old typically were too mobile to capture. Sex ratio at capture was biased toward males (1.5:1), while mean body weight and neck circumference were similar between sexes. Generally, mothers remained in sight during, and immediately reunited with their neonates after, capture. Four percent of the mothers ran out of sight but then returned, while 2% failed to return. Capture-related mortality was 5%, with maternal abandonment in response to capture activities (n = 3) the leading cause. Ear-tag transmitter had minimal effects on subsequent ear position. The success of our technique likely was based on terrain (flat) and vegetative conditions (short grass), high densities of animals for monitoring (particularly in a meadow), and a predictable, pulsed birth season. This hand-capturing method was efficient for handling and marking neonatal vicuñ as. Combined with the use of ear-tag transmitters, it allows the study of important perinatal processes, including movement and mortality.Fil: Donadio, Emiliano.

Luis Ramiro Beltrán: pensador canónico de la Comunicación latinoamericana
No full textLuis Ramiro Beltrán Salmón, who died on July 11th, 2015, was the most important
Bolivian thinker of communication and the standard-bearer of the Latin American
utopia of communication for democratic development with social justice and sovereignty.
He began being a journalist when he was only 12 years old and at his 40 became
a reference point for the specialized critical thinking in the region which basis
helped to build with his intellectual work. His major concerns were communication
and development, communication and democracy, and finally communication research.
His proposals about National Communication Policies, Horizontal Communication
and the Communicology of Liberation are still valid, fact that makes
him into a classic author in the Communication field.Luis Ramiro Beltrán Salmón, fallecido el 11 de julio de 2015, fue el mayor pensador boliviano de la Comunicación y el abanderado de la utopía latinoamericana de la comunicación para el desarrollo democrático con justicia social y soberanía. Se hizo periodista a los 12 años de edad y a los 40 se convirtió en un referente del pensamiento crítico especializado de la región cuyas bases contribuyó a construir con su obra intelectual. Sus grandes preocupaciones fueron la comunicación y el desarrollo, la comunicación y la democracia y la investigación comunicacional. Sus propuestas relativas a las Políticas Nacionales de Comunicación, la Comunicación Horizontal y la Comunicología de Liberación tienen plena vigencia, lo que hace de él en un autor clásico del campo de la Comunicación
La defensoría del lector en Bolivia
No full textA few months ago a self-regulated institution of press activities emerged in Bolivia: the defender of the reader. The Bolivian Communication Specialist, Luis Ramiro Beltrán, talks profoundly about the issue in this presentation, read in public at his installation as defender of the reader in the Group of the Leading Press of his country. He makes us see in it the immense power of the media, that apparently has neither barriers nor brakes, except those that journalists might impose through ethics, a barrier which according to the author must be impervious to excesses and absurdities.Hace unos meses surgió en Bolivia una institución autorregulatoria de la actividad de la prensa escrita: la defensoría del lector, de la que nos habla en profundidad el comunicólogo boliviano Luis Ramiro Beltrán en esta ponencia, leída en el acto público de su iniciación como defensor del lector en el Grupo de Prensa Líder de su país. En ella nos hace ver el poder inmenso de los medios, que no tiene aparentemente barreras ni frenos, excepto los que pueden ponerles los periodistas a través de la ética, muralla que según el autor tiene que ser inexpugnable para los excesos y despropósitos

Niche Expansion of an Invasive Predator (Neovison vison), Prey Response, and Facilitative Interactions with Other Invasive Mammals at the Southern End of the Americas: Conservation Challenges and Potential Solutions
No full textThe Cape Horn Biosphere Reserve is located at the southern tip of South America. This large archipelago is considered one of the last pristine areas left on the world. Despite it being an unpopulated area with most of the native forest cover intact, it has not been exempt from biological invasions, one of the major drivers of biodiversity loss. Three species that naturally interact in their native range in North America – American beavers (Castor canadensis), muskrats (Ondatra zibethicus), and American mink (Neovison vison) – were independently introduced in this remote region. In my dissertation, I investigated (i) the hypothesis of niche expansion in the invasive mink population on Navarino Island towards terrestrial habitats; (ii) potential mink impact on breeding success of forest-bird populations; (iii) habitat selection of small-rodent species and their perception on the mink's novel predation risk; and (iv) the dynamics of multiple-species invasions under the hypothesis of an invasional meltdown. Additionally, I worked within the framework of environmental philosophy. I provide an example of combining ecological and cultural dimensions within the International Long-Term Ecological Research network to disentangle the ethical dilemmas that surround the management of invasive species. I finally proposed a management plan based on the idea of multiple invasive species management, discussing potential solutions to overcome the challenges that the control of invasive species represent and to more effectively protect the biological integrity of the native ecosystems
