Análisis comparativo del proceso de construcción de la política pública en materia migratoria como prioridad en la agenda interna de un estado, caso de estudio: Colombia y Ecuador de 2003 - 2011

Colombia y Ecuador son países que por mucho tiempo no brindaron mayor importancia al tema migratorio y sus políticas enfocadas a dicha materia fueron incipientes y con resultados poco favorables. Desde principios del siglo XXI, el tema migratorio empezó a considerarse como prioridad dentro de las agendas políticas internas de cada Estado y de ahí surge la necesidad de crear políticas migratorias capaces de dar respuesta efectiva a los nuevos flujos migratorios y de proteger a los emigrantes residentes en el exterior por medio de la garantía de sus derechos fundamentales. No obstante, los resultados en la implementación de dichas políticas varío considerablemente entre los dos países debido a la importancia que se le asignó al tema dentro de la agenda política de cada Estado, mientras que en Ecuador la migración es un considerada como una prioridad interna, para Colombia el tema migratorio sigue siendo relegado por otros temas como el conflicto armado y el desplazamiento forzado interno.

Análisis de la incidencia de la Teoría de la Identidad Colectiva en la posición de la Liga Árabe frente al reconocimiento de Somalilandia como Estado independiente

Esta Monografía se centra en mostrar cómo el intento por conservar la identidad colectiva de la Liga de los Estados Árabes impide ceder ante el deseo de Somalilandia de ser reconocida como Estado independiente.

Migración y codesarrollo: una forma de cooperación internacional en el siglo XXI. caso Ecuador - España

Esta monografía busca estudiar la interrelación que hay entre las migraciones internacionales y el surgimiento de proyectos y políticas de codesarrollo entre Ecuador y España. La globalización ha generado nuevas dinámicas internacionales que permiten la creación de nuevos parámetros y marcos para la regulación de las migraciones. A su vez ha sido un catalizador de fenómenos transnacionale; como las migraciones y las mismas políticas de codesarrollo. El transnacionalismo genera procesos con los cuales los migrantes crean y mantienen relaciones que vinculan las sociedades de origen con las receptoras. Por esta razón, la migración ya no puede ser controlada unilateralmente. De esta forma el codesarrollo surge como una medida transnacional para responder a estas nuevas dinámicas migratorias; es una política bilateral que busca obtener beneficios de la migración para ambos países, de modo que esta sea un vector y protagonista positivo del desarrollo.

Este trabajo intenta mostrar, a partir de la experiencia como interlocutor en el Consultorio Social Minuto de Dios (CSMD), las relaciones que se dan entre sus actores (directivas, profesores, practicantes e interloutor) para encontrar si hay distancia entre los discursos y las practicas que se dan.

El mar, la mar.

A través de este proyecto se trata de enfocar de forma global un tema amplio como es el mar, siguiendo el siguiente guión: Nuestro entrono natural (el mar en Colindres, paisaje y medio de vida). Nuestro origen biológico (origen de vida y fauna). Nuestro entorno mas diverso (geografía, mares helados y mares del sur). Nuestro mayor motivo de expresión (literatura y artes plásticas). Nuestro mayor tesoro a conservar (ecología). Los objetivos son los siguientes: 1. Estimular y reforzar las relaciones de los componentes de toda la comunidad escolar, profesores, padres y alumnos mediante proyectos de trabajo en común. 2. Coordinar y programar actividades con organismos y estamentos sociales y culturales del entorno. 3. Aumentar la sensibilidad de los participantes hacia el tema del mar. 4. Investigar sobre aspectos biológicos, geográficos, ecológicos, literarios etc. respecto al tema del mar. 5. Conocer, valorar y expresar las obras realizadas en la literatura y el arte sobre el mar. 6. Promover y animar a la lectura por medio de los clásicos y aventuras del mar. 7. Conocer y valorar el entorno marino más próximo. 8. Investigar el pasado de Colindres, el puerto, los astilleros etc. Los grandes temas relacionados son los siguientes: Mar de Colindres, Mar biológico. Mar Geográfico. Mar ecológico. Mar artístico..

Suitability of cryopreservation for the long-term storage of rare and endangered plant species: a case history for Cosmos atrosanguineus

The suitability of cryopreservation for the secure, long-term storage of the rare and endangered species Cosmos atrosanguineus was investigated. Using encapsulation/dehydration of shoot tips in alginate strips, survival rates of up to 100 % and shoot regeneration of up to 35 % were achieved. Light and electron microscopy studies indicated that cellular damage to some regions of the shoot tip during the freeze/thaw procedure was high, although cell survival in and around the meristematic region allowed shoot tip regeneration. The genetic fingerprinting technique, amplified fragment length polymorphisms (AFLPs), showed that no detectable genetic variation was present between material of C. atrosanguineus at the time of initiation into tissue culture and that which had been cryopreserved, stored in liquid nitrogen for 12 months and regenerated. Wearied plantlets that were grown under glasshouse conditions exhibited no morphological variation from non-frozen controls. (C) 2003 Annals of Botany Company.

Genetic structure and systematic relationships within the Ophrys fuciflora aggregate (Orchidaceae: Orchidinae): high diversity in Kent and a wind-induced discontinuity bisecting the Adriatic

A recent phylogenetic study based on multiple datasets is used as the framework for a more detailed examination of one of the ten molecularly circumscribed groups identified, the Ophrys fuciflora aggregate. The group is highly morphologically variable, prone to phenotypic convergence, shows low levels of sequence divergence and contains an unusually large proportion of threatened taxa, including the rarest Ophrys species in the UK. The aims of this study were to (a) circumscribe minimum resolvable genetically distinct entities within the O. fuciflora aggregate, and (b) assess the likelihood of gene flow between genetically and geographically distinct entities at the species and population levels. Fifty-five accessions sampled in Europe and Asia Minor from the O. fuciflora aggregate were studied using the AFLP genetic fingerprinting technique to evaluate levels of infraspecific and interspecific genetic variation and to assess genetic relationships between UK populations of O. fuciflora s.s. in Kent and in their continental European and Mediterranean counterparts. The two genetically and geographically distinct groups recovered, one located in England and central Europe and one in south-eastern Europe, are incongruent with current species delimitation within the aggregate as a whole and also within O. fuciflora s.s. Genetic diversity is higher in Kent than in the rest of western and central Europe. Gene flow is more likely to occur between populations in closer geographical proximity than those that are morphologically more similar. Little if any gene flow occurs between populations located in the south-eastern Mediterranean and those dispersed throughout the remainder of the distribution, revealing a genetic discontinuity that runs north-south through the Adriatic. This discontinuity is also evident in other clades of Ophrys and is tentatively attributed to the long-term influence of prevailing winds on the long-distance distribution of pollinia and especially seeds. A cline of gene flow connects populations from Kent and central and southern Europe; these individuals should therefore be considered part of an extensive meta-population. Gene flow is also evident among populations from Kent, which appear to constitute a single metapopulation. They show some evidence of hybridization, and possibly also introgression, with O. apifera.

Friends or relatives? Phylogenetics and species delimitation in the controversial European orchid Genus ophrys

Background and Aims Highly variable, yet possibly convergent, morphology and lack of sequence variation have severely hindered production of a robust phylogenetic framework for the genus Ophrys. The aim of this study is to produce this framework as a basis for more rigorous species delimitation and conservation recommendations. Methods Nuclear and plastid DNA sequencing and amplified fragment length polymorphism (AFLP) were performed on 85 accessions of Ophrys, spanning the full range of species aggregates currently recognized. Data were analysed using a combination of parsimony and Bayesian tree-building techniques and by principal coordinates analysis. Key Results Complementary phylogenetic analyses and ordinations using nuclear, plastid and AFLP datasets identify ten genetically distinct groups (six robust) within the genus that may in turn be grouped into three sections (treated as subgenera by some authors). Additionally, genetic evidence is provided for a close relationship between the O. tenthredinifera, O. bombyliflora and O. speculum groups. The combination of these analytical techniques provides new insights into Ophrys systematics, notably recognition of the novel O. umbilicata group. Conclusions Heterogeneous copies of the nuclear ITS region show that some putative Ophrys species arose through hybridization rather than divergent speciation. The supposedly highly specific pseudocopulatory pollination syndrome of Ophrys is demonstrably 'leaky', suggesting that the genus has been substantially over-divided at the species level.
