Guía de estudio núm. 99. Man Ray
El vigor que el artista estadounidense Man Ray (seudónimo de Emmanuel Radnitsky) le imprimió a las vanguardias de su época y la fuerza con que subvirtió las formas tradicionales del arte evidencian la influencia del dadaísmo y el surrealismo en su obra. Precisamente, esta guía de estudio sintetiza el marco histórico de ambos movimientos antes de referirse a su carrera artística en Manhattan y París. Con la referencia a algunas de sus obras se ejemplifica la experimentación progresiva de sus técnicas como pintor, creador de objetos y fotógrafo, especialmente su técnica de rayografías y solarizaciones. Incluye ocho imágenes

Biografía e historiografía en las novelas " Author, author!: a novel" y "A man of parts: a novel" de David Lodge
[ES] El presente trabajo de investigación indaga en la evolución estilística del escritor británico David Lodge, señalando que aquellas novelas publicadas por el autor durante la primera década del siglo XXI difieren en ciertos aspectos de su producción literaria correspondiente al siglo XX. Para ello, en la primera parte de la investigación se analiza los fundamentos teóricos subyacentes al estilo literario en Author y a Man of Parts. En la segunda parte, los aspectos formales y temáticos referentes al estilo literario en Author y a Man of Parts. Dichas novelas se conforman como un tipo de creación que persigue verdades que acotan hechos concretos y cabales, la denominada truth in facts, a la vez que expresan la narrativa de vivencias o life-writing, escritura que manifiesta experiencias personales en forma de confesión o diario. Consecuentemente, en dichas obras literarias, David Lodge opta por reflejar la llamada ʽnovela de autor,ʼ decantándose por delinear ficcionalmente las biografías de los escritores consagrados decimonónicos Henry James y H. G. Wells
Model-Based Assessment of C-Peptide Secretion and Kinetics in Post Gastric Bypass Individuals Experiencing Postprandial Hyperinsulinemic Hypoglycemia
Assessment of insulin secretion is key to diagnose postprandial hyperinsulinemic hypoglycemia (PHH), an increasingly recognized complication following bariatric surgery. To this end, the Oral C-peptide Minimal Model (OCMM) can be used. This usually requires fixing C-peptide (CP) kinetics to the ones derived from the Van Cauter population model (VCPM), which has never been validated in PHH individuals. The objective of this work was to test the validity of the OCMM coupled with the VCPM in PHH subjects and propose a method to overcome the observed limitations. Two cohorts of adults with PHH after gastric bypass (GB) underwent either a 75 g oral glucose (9F/3M; age=42±9 y; BMI=28.3±6.9 kg/m2) or a 60 g mixed-meal (7F/3M; age = 43 ± 11 y; BMI=27.5±4.2 kg/m2) tolerance test. The OCMM was identified on CP concentration data with CP kinetics fixed to VCPM (VC approach). In both groups, the VC approach underestimated CP-peak and overestimated CP-tail suggesting CP kinetics predicted by VCPM to be inaccurate in this population. Thus, the OCMM was identified using CP kinetics estimated from the data (DB approach) using a Bayesian Maximum a Posteriori estimator. CP data were well predicted in all the subjects using the DB approach, highlighting a significantly faster CP kinetics in patients with PHH compared to the one predicted by VCPM. Finally, a simulation study was used to validate the proposed approach. The present findings question the applicability of the VCPM in patients with PHH after GB and call for CP bolus experiments to develop a reliable CP kinetic model in this population
The Man, The Boy, and The Donkey
MSA is here told in Amharic. Our 79th language! The story is told in typical fashion, though the ending is surprising. There is no death of the donkey, nor is there a decision by the man. The last word goes to passersby who comment "You fools! Do you carry donkeys?" The moral is, in Google translate, "If you try to please everyone, you can please no one." Strong simple illustrations have the two walking through desert to Gebiya. 46 pages. 6" x 9".This is a hardbound book (hard cover)Language note: AmharicNo Autho
Traumatic renewal of values and value criteria in crisis management
This work tries to be an empirical sample in the study of learning in public policies, that is, how learning is linked to policy change. Particularly, we have studied political-administrative elites’ learning process on crisis provoked by oil spill off the coast of Spain.
After expounded our premises about policy learning and the working hypothesis that have guided our work, we explain the methodology we have employed: the Nominal Group Technique, its advantages in this kind of research and how we used it.
Finally, we display the reflection generated from the empirical work to better understand policy learning process. In this sense, political factors have been revealed as absolutely essential in order to explain what political-administrative elites learn and whatever they decide to implement. Aspects that make crises different from each other (these being technical aspects) show up as less important than political ones. Political aspects make crisis similar, because of political reasons behind the decision, communication, and attention strategies.
Two concepts have appeared as the connection of crisis and elites’ learning: sensitization and political profitability. The former means the process of becoming fully aware of the problem, being concerned about it, and predisposed towards a faster and more coherent action. At the same time, it is difficult to imagine a government undertaking polices that involve political costs, or anything proved to be unprofitable. This is especially true of learning and implementation of whatever has been learnt from crisis that happened in distant points of time
Aspectos biodemográficos de grupos étnicos Macro-Pano de Bolivia y caracterización genética de las poblaciones Aymará, Quechua, Chimane y Mosetén
[spa] La tesis trata de definir algunos aspectos de la situación demográfica y describir la genética poblacional a partir del estudio de haplogrupos del ADN mitocondrial (ADNmt), secuenciación de la región de control d-loop del ADNmt (HVRI), de microsatélites autosómicos, short tandem repeats (STR´s) y microsatélites del cromosoma Y de un grupo de etnias asentadas en el Piedemonte del Departamento del Beni de Bolivia. Las poblaciones Mosetén y Chimane son autóctonas de la zona mientras que las poblaciones Aymará y Quechua deben considerarse colonas en la región ya que su área de poblamiento original se halla en otros departamentos, mayoritariamente andinos.
Las poblaciones autóctonas, si bien presentan una cultura común, pertenecen a grupos lingüísticos claramente diferenciados. Las etnias Mosetén y Chimane son de habla Ge-Pano-Caribe, mientras que las poblaciones Aymará y Quechua pertenecen al stock de lenguas Andinas.
Las poblaciones del Piedemonte andino boliviano son potencialmente muy interesantes en el contexto de la biología y la evolución humana dada su ubicación geográfica a medio camino de la zona andina y la amazónica y por el contexto de su historia.
El piedemonte es una ruta natural de paso entre las dos áreas que presenta una historia demográfica compleja con llegadas migratorias primitivas, influencias incaicas y reducciones franciscanas y jesuíticas que influyeron en la dinámica poblacional de los grupos que allí habitaban y que, en la actualidad, si bien mantienen sus peculiaridades culturales y lingüísticas, poseen un reducido efectivo poblacional. Por otro lado, los movimientos migratorios más recientes de otras poblaciones hacen de la región del Piedemonte una zona excelente para estudiar la diversidad y microdiferenciación de las poblaciones humanas en el continente americano.[eng] The thesis attempts to define the demographic situation of a group of Macro-Panoan linguistic populations living in the Piedmont foothills of the Beni Department (Bolivia) and describe the population genetics of these populations using mitochondrial DNA haplogroups, mtDNA hipervariable region I (HVRI) of the control region, autosomal microsatellites (STR's) and Y-chromosome microsatellites (Y-STR’s).
Moseten and Chimane populations are autochthonous indigenous of the area while Aymara and Quechua populations should be considered new settlers in the region since their original settlements are the Andean Departments.
These two groups of populations belong to distinct linguistic clusters. Chimane Moseten belong to Ge-Pano-Carib speaking group while the Aymara and Quechua populations belong to the Andean language stock.
Populations of the Bolivian piedmont are potentially interesting in the context of biology and human evolution because of its location halfway between the Andes and the Amazon areas and the context of its history.
The piedmont is a natural passage between the two areas with a complex demographic history with primitive migratory arrivals, Inca influences and Franciscan and Jesuit reductions that influenced the population dynamics of the groups who lived in this territory in the past. Populations who live in piedmont nowadays, maintain their linguistic and genetic diversity although they have a reduced effective population. On the other hand, more recent migration of other populations make the region an excellent location to study the diversity and microdifferentiation of human population in the Americas
Spatially-localized time dependent solutions including turbulence and their interactions in 2D Kolmogorov flow
In 2D Kolmogorov flow in small aspect ratio domains, spatially-localized solutions such as kink, traveling or time-dependent kink-antikink pars coexist. However, the conservation of the flow rate in the y direction strongly restrict combination of localized solutions and their positioning. We find that by adding a homogeneous flow U y their positioning is controlled and each of localized solutions including a spatially-localized chaos is isolated. Numerical results suggest that these isolated solutions can be elements constructing a whole flow
