La industria cultural en Internet y las entidades gestoras de derechos de autor

En el presente trabajo de investigación realizamos un análisis sobre el impacto de la revolución digital en las industrias culturales. Reflejamos como el Derecho español se adapta a las nuevas necesidades de la tecnología para garantizar la protección de la Propiedad Intelectual (PI). Indagamos en las competencias de las entidades de gestión y que se encargan de la gestión de los derechos de autor así como la aplicación conjunta del canon digital. Nuestro objetivo general es mostrar cuales son las particularidades del nuevo contexto cultural-digital, esclareciendo cual es el papel que cada uno de los actores implicados desarrolla, así como mostrar cual es el valor económico, legal y social que esta tendencia de consumo representa para el desarrollo cultural y tecnológico en el territorio español. iv.

Ciencia, industria e ideología en la Cataluña del siglo XX: el Instituto Ravetllat-Pla en Sudamérica entre 1924 y 1936

En 1923, Ramón Plá i Armengol (1880-1958) fundó el Instituto Ravetllat-Pla para la comercialización y producción de dos productos antituberculosos (Hemo-Antitoxina y Suero Ravetllat-Pla) fundamentados en una teoría heterodoxa postulada por el veterinario Joaquim Ravetllat i Estech (1871-1923). A través del instituto creó una gran red internacional científico-comercial principalmente en Latinoamérica. Plá i Armengol fue doctor en medicina y participó activamente en la lucha antituberculosa en Cataluña sin dejar de lado su militancia socialista. A través de estos dos productos, logró crear un mercado que se sustentaba en una teoría heterodoxa que integraban sus principios e ideología.

Ecology of phlebotomine sand flies (Diptera: Psychodidae)in a focus of Leishmania (Viannia) brasiliensis in northeastern Colombia

The phlebotomine sand fly fauna of two coffee plantations in a Leishmania-endemic area of Norte de Santander, Colombia was studied. Regular insect collections using a variety of methods were made for three and a half years. Information was obtained on diurnal resting sites, host range and seasonal abundance for 17 species, of wich five (Lutzomyia spinicrassa, Lu. serrana,Lu. shannoni, Lu. ovallesi and Lu. gomezi) were far more numerous than the others, anthropophilic and present throughout the year. The behaviour of these and the remaining 12 species is discussed in relation to their potential role in transmission of Leishmania (Viannia) brasiliensis in the area.

Naturally acquired antibodies against the major merozoite surface coat protein (MSP-1) of Plasmodium falciparum acquired by residents in an endemic area of Colombia

A preliminary baseline epidemiological malaria survey was conducted in the village of Punta Soldado, Colombia. Parasite prevalence and density as well as serological data were obtained from 151 asymptomatic children and adults. Fifty individuals were infected with Plasmodium falciparum. The mean parasite density was 184 parasites/mm3. Greater than 90 of the sample population were P. falciparum antibody positive as detected by the indirect immunofluorescent antibody test (IFAT). The enzyme-linked immunosorbent assay (ELISA) was used to detect antibodies against the major merozoite surface protein (MSP-1) of P. falciparum. In this population, anti-MSP-1 antibody concentration is acquired in an age dependent manner with equal immunogenicity to both the N- and C-terminal regions of the molecule. Infection at the time of sampling was associated with a higher anti-MSP-1 antibody concentration than that found in non-infected individuals. Further studies are planned to assess the role of immune and non-immune factors in limiting the number of cases of severe malaria seen in this population.

Genetic variability and differentiation between populations of Rhodnius prolixus and R. pallescens, vectors of Chagas' Disease in Colombia

Enzyme polymorphism in Rhodnius prolixus and R. pallescens (Hemiptera, Reduviidae), principal vectors of Chagas' disease in Colombia, was analyzed using starch gel electrophoresis. Three geographic locations were sampled in order to determine gene flow between populations and to characterize intra- and interspecific differences. Of 25 enzymes assayed 10 were successfully resolved and then used to score the genetic variation. The enzymes PEPD, GPI, PGM and ICD were useful to differentiate these species and PGD, PGM and MDH distinguished between sylvatic and domiciliary populations of R. prolixus. Both polymorphism and heterozygosity indicated greater genetic variability in sylvatic habitats (H = 0.021) compared to domiciliary habitats (H = 0.006) in both species. Gene flow between sylvatic and domiciliary populations in R. prolixus was found to be minimal. This fact and the genetic distance between them suggest a process of genetic isolation in the domiciliary population.

Indigenous people's mobilization and their struggle for rights in Colombia

This text aims at showing the history of indigenous peoples’ mobilization in Colombia, the effects that it has brought about on Colombian democracy and political system, and the state’s reactions to their claims and actions. It will show how they have moved from class-based claims to a politics where identity claims have been central in their agenda and part of their strategies to negotiate with the state. It will also show the existing constitutional and legal framework that recognizes the rights of indigenous peoples, despite the context of persecution, murder, and forced displacement.
