Stages for the More Sustainable Farm
No full textCurrently, agricultural farm units are faced with a double and most times contradictory challenge, in order to be successful: on the one hand the invested capital has to be profitable and the economic performance has to be maximised. On the other hand, given the socio-environmental situation, it is necessary to preserve and to protect the environment and natural resources. Given the potential conflict of the two aims, since the satisfaction of one implies the underperformance of the other (and vice versa), the question then is: which is the solution to choose? We intend, in this work, to formulate a farm plan with the purpose of reconciling the criteria of environmental sustainability with that of economic competitiveness. For this achievement we proceed to the comparative study of sustainability of different groups of farms identified in the study area (first evaluation cycle) through MESMIS (“Marco para la Evaluación de Sistemas de Manejo de Recursos Naturales Mediante Indicadores de Sustentabilidad” - Framework for Evaluation of Natural-Resource Systems Handling through Sustainability Indicators) methodology, that allowed to select the more sustainable group of farms. Based on the found potentialities and weakness on these production systems, we stepped to the planning of a production unit of bovine meat, which obeys simultaneously to economic and environmental objectives, using Multicriteria Decision. We finished the work with the sustainability evaluation between groups of farms identified previously and the planned farms (second evaluation cycle), based, again, in the MESMIS methodology, to confirm (or not) the greatest sustainability of the last ones. Analyses of the results allow us to confirm the greatest relative sustainability of the planned farm, for the diverse traced scenarios.Decision taking, planning, sustainability, Environmental Economics and Policy, Farm Management,

Nikolai Evreinov and Edith Craig as Mediums of Modernist Sensibility
No full textNikolai Evreinov (1870-1953) was a Russian playwright, director, and theorist of the theatre who played a leading part in the modernist movement of Russian theatre. Evreinov's 1911 monodrama The Theatre of the Soul (V kulisakh dushi) was staged by the Crooked Mirror theatre in St Petersburg in 1912. It was also performed in London (1915) and Rome (1929), and inspired Man Ray to create his aerograph The Theatre of the Soul (1917). In this article Alexandra Smith links Evreinov's play to Russian modernist thought shaped by the atmosphere of crisis associated with the Russo-Japanese War and the first Russian Revolution. It demonstrates that Edith Craig's production of Evreinov's play suggests that the philosophy of theatricalization of everyday life might enable modern subjects to overcome the fragmentation of modern society. Craig's use of the montage-like techniques of Evreinov's play prefigures cinematographic experiments of the 1920s and Marinetti's notion of synthetic theatre. Alexandra Smith is a Reader in Russian Studies at the University of Edinburgh and is the author of The Song of the Mockingbird: Pushkin in the Works of Marina Tsvetaeva (1994) and Montaging Pushkin: Pushkin and Visions of Modernity in Russian Twentieth-Century Poetry (2006), as well as numerous articles on Russian literature and culture.</p
Degenerate partial differential equations and applications to probability theory and foundations of mathematical finance
No full textIn the first part of our thesis, we prove existence, uniqueness and regularity of solutions for a certain class of degenerate parabolic partial differential equations on the half space which are a generalization of the Heston operator. We use these results to show that the martingale problem associated with the differential operator is well-posed and we build generalized Heston-like processes which match the one-dimensional probability distributions of a certain class of It^o processes. The second part of our thesis is concerned with the study of regularity of solutions to the variational equation associated to the elliptic Heston operator. With the aid of weighted Sobolev spaces, we prove supremum bounds, a Harnack inequality, and H"older continuity near the boundary for solutions to elliptic variational equations defined by the Heston partial differential operator. Finally, we establish stochastic representations of solutions to elliptic and parabolic boundary value problems and obstacle problems associated to the Heston generator. In mathematical finance, solutions to parabolic obstacle problems correspond to value functions for American-style options.Ph. D.Includes bibliographical referencesby Camelia Alexandra Po
CR1 Knops blood group alleles are not associated with severe malaria in the Gambia
No full textThe Knops blood group antigen erythrocyte polymorphisms have been associated with reduced falciparum malaria-based in vitro rosette formation (putative malaria virulence factor). Having previously identified single-nucleotide polymorphisms (SNPs) in the human complement receptor 1 (CR1/CD35) gene underlying the Knops antithetical antigens Sl1/Sl2 and McC(a)/McC(b), we have now performed genotype comparisons to test associations between these two molecular variants and severe malaria in West African children living in the Gambia. While SNPs associated with Sl:2 and McC(b+) were equally distributed among malaria-infected children with severe malaria and control children not infected with malaria parasites, high allele frequencies for Sl 2 (0.800, 1,365/1,706) and McC(b) (0.385, 658/1706) were observed. Further, when compared to the Sl 1/McC(a) allele observed in all populations, the African Sl 2/McC(b) allele appears to have evolved as a result of positive selection (modified Nei-Gojobori test Ka-Ks/s.e.=1.77, P-valu
La creación del personaje femenino: una aproximación desde la obra de Gilma Peña y Alexandra Cardona.
No full textEste trabajo indaga en el proceso creativo que las guionistas Gilma Peña y Alexandra Cardona llevan a cabo en la construcción de personajes femeninos. A partir de entrevistas semiestructuradas y del análisis fílmico de algunas escenas de las producciones ¿Por qué diablos? y Confesión a Laura, se describe el aporte que las escritoras hicieron a la representación de las mujeres en las pantallas colombianas. Asimismo, como apuesta por la creación y como resultado de este ejercicio investigativo, se lleva a cabo la escritura de un guión propio para explorar cómo los métodos, estilos y enfoques narrativos de estas guionistas pueden inspirar y contribuir en la creación de historias y protagonistas femeninas.This work explores the creative process that screenwriters Gilma Peña and Alexandra Cardona employ in constructing female characters.

New aspects of security: citizens’ attitudes towards the issue of information regulation in Russia
No full text. The effectiveness of government policies to ensure cyber- and information security directly depends on how successfully such measures are followed by citizens at the national level. The author considers the influence of cognitive-rational, value-affective, and socio-demographic factors on respondents' support for government policy in the field of information regulation through selected cases of regulating social networks and introducing a mandatory face recognition system in public transport. In the course of the study, a factorial survey (N=395) was conducted using vignettes to examine the effects of framing on respondents' perception of the measures proposed. The analysis of the experimental results in this study shows that news framing to persuade the population to support the proposed measures does not lead in the short term to an increase in support for the measures. However, certain factors influencing public perception, such as civic identity, trust in the political system, and assessment of cyber threats danger, show less variability over time. The results of the study allow us to confirm the hypothesis of a direct connection between civic identity and support for restrictive measures, as well as partially confirm the assumption that the political trust of citizens and the specifics of perception of cyber threats positively influence support for the introduction of measures. In addition, the heterogeneity of support for government measures at various levels of political trust of respondents was revealed, therefore we can identify the further potential of research on public perception of such measures taking into account trust in the political system and individual political actors (government, special services, army, etc.) in Russia
