Pintar la nación indígena como una estrategia modernista en la obra de Eduardo Kingman (Dossier: historia del arte)

Este estudio centra su análisis en la obra pictórica de Eduardo Kingman como un modelo para describir los enfoques, tendencias e ideología que caracterizaron al Indigenismo. Esta corriente artística reunió a pintores, escritores e intelectuales ecuatorianos durante la década de 1930. El artículo propone que esta corriente surgió como una reacción al academicismo predominante en los salones y escuelas de arte. El estudio hace una revisión de las exposiciones, bienales y concursos en los que Kingman participó.Analiza las influencias artísticas y literarias reflejadas en la obra de este autor,sus relaciones con el Grupo de Guayaquil y su vinculación al Sindicato de Escritores y Artistas del Ecuador (SEA). Finalmente, recoge la opinión y reacción a su producción pictórica por parte de escritores, intelectuales y prensa en general.

Bayesian non-parametrics and the probabilistic approach to modelling.

Modelling is fundamental to many fields of science and engineering. A model can be thought of as a representation of possible data one could predict from a system. The probabilistic approach to modelling uses probability theory to express all aspects of uncertainty in the model. The probabilistic approach is synonymous with Bayesian modelling, which simply uses the rules of probability theory in order to make predictions, compare alternative models, and learn model parameters and structure from data. This simple and elegant framework is most powerful when coupled with flexible probabilistic models. Flexibility is achieved through the use of Bayesian non-parametrics. This article provides an overview of probabilistic modelling and an accessible survey of some of the main tools in Bayesian non-parametrics. The survey covers the use of Bayesian non-parametrics for modelling unknown functions, density estimation, clustering, time-series modelling, and representing sparsity, hierarchies, and covariance structure. More specifically, it gives brief non-technical overviews of Gaussian processes, Dirichlet processes, infinite hidden Markov models, Indian buffet processes, Kingman's coalescent, Dirichlet diffusion trees and Wishart processes.

Apuntes para una historia del gremio de albañiles de Quito. Ciudad y cultura popular (Estudios)

A partir de entrevistas realizadas a miembros del gremio de albañiles de Quito, el artículo formula algunas hipótesis sobre la formación de la cultura popular en la primera mitad del siglo xx. El gremio de albañiles se desarrolló en el contexto de una ciudad que pretendía ser moderna pero que, al mismo tiempo, reprodujo el privilegio y determinadas formas de violencia simbólica propias de una sociedad más tradicional. Frente a estas concepciones de privilegio, el estudio explora las nociones de raza popular y de respeto que emergen desde el espacio popular. Paralelamente, el artículo discute algunos problemas metodológicos y éticos relacionados con el método biográfico y con la posibilidad de escribir una historia de los trabajadores.

Proteins, Pathogens, and Failure at the Composite-Tooth Interface

In the United States, composites accounted for nearly 70% of the 173.2 million composite and amalgam restorations placed in 2006 (Kingman et al., 2012), and it is likely that the use of composite will continue to increase as dentists phase out dental amalgam. This trend is not, however, without consequences. The failure rate of composite restorations is double that of amalgam (Ferracane, 2013). Composite restorations accumulate more biofilm, experience more secondary decay, and require more frequent replacement. In vivo biodegradation of the adhesive bond at the composite-tooth interface is a major contributor to the cascade of events leading to restoration failure. Binding by proteins, particularly gp340, from the salivary pellicle leads to biofilm attachment, which accelerates degradation of the interfacial bond and demineralization of the tooth by recruiting the pioneer bacterium Streptococcus mutans to the surface. Bacterial production of lactic acid lowers the pH of the oral microenvironment, erodes hydroxyapatite in enamel and dentin, and promotes hydrolysis of the adhesive. Secreted esterases further hydrolyze the adhesive polymer, exposing the soft underlying collagenous dentinal matrix and allowing further infiltration by the pathogenic biofilm. Manifold approaches are being pursued to increase the longevity of composite dental restorations based on the major contributing factors responsible for degradation. The key material and biological components and the interactions involved in the destructive processes, including recent advances in understanding the structural and molecular basis of biofilm recruitment, are described in this review. Innovative strategies to mitigate these pathogenic effects and slow deterioration are discussed.

Penobscot County, Maine, 1859 (Image 2 of 2) (Raster Image)

This layer is a georeferenced raster image of the historic paper map entitled: Topographical map of the county of Penobscot Maine, from surveys under the direction of H.F. Walling; field work under the direction of L.H. Eaton. It was published by Lee & Marsh in 1859, Scale 1:80,000. This layer is image 2 of 2 total images, representing the northeast portion of the four sheet source map. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Universal Transverse Mercator projection (UTM Zone 19N, meters, NAD1983). All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as roads, railroads, drainage, public buildings, schools, churches, cemeteries, industry locations (e.g. mills, factories, mines, etc.), private buildings with names of property owners, town boundaries, and more. Relief shown by hachures. It includes many cadastral insets of individual county towns and villages. It also includes illustrations, business directories, and tables of statistics and distances.This layer is part of a selection of digitally scanned and georeferenced historic maps of New England from the Harvard Map Collection. These maps typically portray both natural and manmade features. The selection represents a range of regions, originators, ground condition dates, scales, and map purposes.
