This paper offers a brief analysis of the legal aspects of the ethnic return migration policy of Kazakhstan, a post-Soviet Central Asian state that has been active in seeking ties with its diaspora since independence. This paper examines the definition of oralman (repatriates) and the establishment of a quota on the number of Kazakh immigrants who are eligible for government funds to show how the rationale and preferences in repatriation policy have changed over the years. By focusing on changes in migration-related legislation in the late 2000s and early 2010s, the paper notes that two key goals of Kazakhstan’s migration policy are not necessarily consistent with each other: the promotion of an ethnically based nation-building project by encouraging the "return" of co-ethnics living abroad, and building a workforce that is best suited for the development of the state’s economy.

En el archivo de la Fundación Casa de Ganaderos se custodia documentación desde la fundación de esta institución en 1218. Aunque no conservan mapas ni descripciones de las cabañeras (nombre que se designa en Aragón a las cañadas) de Aragón y al ser una cofradía adscrita al término de Zaragoza se tienen datos sobre privilegios y derechos en todo Aragón. Especialmente relevante son las mojonaciones del término de Zaragoza. De su estudio geográfico y geomorfológico se deducen interesantes conclusiones de la trashumancia transterminante tan propia del Reino de Aragón y Navarra y el valle del Ebro. Sobre dichas bases pecuarias se entreve la formación y evolución de las redes de comunicaciones rodadas nacidas durante los siglos XVIII y XIX ante el declive de la industria ganadera española. Su marcado carácter apegado a las características geomorfológicas y su evolución y transformación son objeto de este trabajo

En los estudios de la Diplomatura de Enfermería existe una división, tanto a nivel secuencial-cronológico (transmisión gradual y lógica de los contenidos), como en la dimensión espacio-ambiental (aula, sala simulación y servicio sanitario: comunitario u hospitalario). Estas divisiones tienen consecuencias en la estructura curricular de la disciplina: módulo teórico, módulo práctico y módulo práctico-clínico, confiriéndole a estos estudios una peculiaridad asentada en las diferencias en los tipos de escenarios, ambientes, instituciones, normas, y personas que se manifiestan en los contrastes percibidos (Merleau Ponty, 1988) por los alumnos en su proceso de enseñanza-aprendizaje según se dé éste en un módulo u otro. La enorme variabilidad de la práctica se ve también afectada por las características del escenario en el que tienen lugar las prácticas clínicas: centros de atención primaria y/o instituciones hospitalarias, en los que el alumno debe iniciar sus prácticas de enfermería con el que va a constituir su objeto-sujeto de trabajo durante toda su vida profesional: el ser humano (individuo, familia y comunidad) atendiendo a sus necesidades fisiológicas, psicológicas y sociales desde una perspectiva holística. Los contrastes entre el aula y el servicio sanitario suponen a veces contradicciones que desenfocan la visión lógica con la que el alumno pretende interpretar su realidad formativa en esta compleja fase de sus estudios, y esta visión borrosa puede derivar en situaciones de disminución o pérdida de significado que esta experiencia educativa debe tener en el alumno (Bruner, 1991).

A simple change in the polarity of the solvent allows both enantiomers of substituted succinimides to be obtained in the enantioselective conjugate addition reaction of aldehydes, mainly α,α-disubstituted, to maleimides catalysed by chiral carbamate-monoprotected trans-cyclohexane-1,2-diamines. Using a single enantiomer of the organocatalyst, both enantiomers of the resulting Michael adducts are obtained in high yields by simply changing the reaction solvent from aqueous DMF (up to 84 % ee) to chloroform (up to 86 % ee). Theoretical calculations are used to explain this uncommon reversal of the enantioselectivity; two transition state orientations of different polarities are differently favoured in polar or nonpolar solvents.

Tras 30 años del Estado de las Autonomías nos parece oportuno estudiar el origen y desarrollo de Castilla-La Mancha, uno de los territorios pluriprovinciales con mayores problemas de ordenación integral, haciendo una breve referencia al pasado, a Castilla la Nueva. De la actual Comunidad Autónoma de Castilla-La Mancha nos ha interesado analizar el desarrollo territorial en sus distintas escalas, así como la política de ordenación territorial del conjunto regional, señalando la aportación llevada a cabo desde la Geografía.

We present the first high-resolution organic carbon mass accumulation rate (MAR) data set for the Eocene equatorial Pacific upwelling region, from Sites 1218 and 1219 of the Ocean Drilling Program. A maximum Corg MAR anomaly appears at 41 Ma and corresponds to a high carbonate accumulation event (CAE). Independent evidence suggests that this event (CAE-3) was a time of rapid cooling. Throughout the Eocene, organic carbon burial fluxes were an order of magnitude lower than fluxes recorded for the Holocene. In contrast, the expected organic carbon flux, calculated from the biogenic barium concentrations for these sites, is roughly equal to modern. A sedimentation anomaly appears at 41 Ma, when both the measured and the expected organic carbon MAR increases by a factor of two-three relative to the background Eocene fluxes. The rain of estimated Corg and barium from the euphotic zone to the sediments increased by factors of three and six, respectively. We suggest that the discrepancy between the expected and measured Corg in the sediments is a direct consequence of the increased metabolic rates of all organisms throughout the Eocene oceans and sediments. This hypothesis is supported by recent work in ecology and biochemical kinetics that recognizes the fundamental basis of ecology as following from the laws of thermodynamics. This dependence is now elucidated as the Universal Temperature Dependence (UTD) "law" of metabolism and can be applied to all organisms over their biologically relevant temperature range. The general pattern of organic carbon and barium deposition throughout the Eocene is consistent with the UTD theory. In particular, the anomaly at 41 Ma (CAE-3) is associated with rapid cooling, an event that triggered slower metabolic rates for all organisms, slower recycling of organic carbon in the water and sediment column, and, consequently, higher deposition of organic carbon in the sediments. This "metabolism-based" scenario is consistent with the sedimentation patterns we observe for both Sites 1218 and 1219.
