Reflection Reframed: The Process of Photography as Strategy for Teachers' Reflective Practice

Teacher reflective practice is described as an effective method for engaging teachers in improving their own professional learning. Yet, some teachers do not understand how to effectively engage in the reflective processes, or prefer not to formalize the process through writing a reflective journal as taught in most teacher education programs. Developing reflective skills through the process of photography was investigated in this study as a strategy to allow enhanced teacher reflection for professional and personal growth. The process of photography is understood as the mindful act of photographing rather than focusing on the final product-the image. For this study, 3 practicing educators engaged in photographic exercises as a reflective process. Data sources included transcribed interviews, participant journal reflections, and sketchbook artifacts, as well as the researcher's personal journal notes. Findings indicated that, through the photographic process, (a) teacher participants developed new and individual strategies for professional leaming; and (b) teacher participants experienced shifts in the way they conceptualized their personal worldviews.

This collection contains 129 aerial photographs of the Niagara region. The dates vary from 1921-1991, with some photos undated. Some of the areas covered include the Welland Canal, the Queen Elizabeth Way (QEW), Niagara Falls, the Short Hills, and St. Catharines. Most of the photos are black and white.

Orientalisme 2.0 : la Révolution verte iranienne en images

Depuis la colonisation jusqu’aux plus récents conflits qui affectent le « Moyen-Orient », le visuel participe à la création d’une image raciale et sexuelle du monde musulman dans laquelle l’Orient « archaïque » est représenté comme l’opposé moral de l’Occident « moderne ». Ce discours nommé Orientalisme (Saïd 1994) transforme l’Orient en objet du savoir et du regard occidental (Nochlin 1989). La peinture, la photographie, et les expositions universelles sont autant de moyens qui permettent d’instaurer un point de vue privilégié de l’Occident sur l’Orient. Avec le Web 2.0 et les technologies mobiles, le partage d’images fait partie intégrale de notre quotidien et celles-ci nous proviennent de partout et de n’importe qui. En considérant que l’Orientalisme est indissociable des techniques modernes de représentation du monde (Mitchell 2013), le présent mémoire souhaite interroger l’impact de ces nouvelles technologies sur la production, la circulation et la réception des images du dit Orient. Nous concentrerons notre étude sur les images captées et partagées depuis les manifestations de la Révolution verte iranienne de juin 2009, entre autres la vidéo de l’assassinat de la jeune Neda Agha Soltan qui a fait la une des médias occidentaux. En prenant comme base les écrits d’Edward Saïd, que nous réviserons par le biais de lectures féministes, nous verrons que l’Orientalisme visuel mute au rythme des changements politiques, culturels et technologiques qu’il rencontre. En plus d’éclairer les images de notre corpus, la question féministe nous permettra d’élargir la définition et les mécanismes de l’Orientalisme proposés par Saïd. Nous démontrerons que tout en ayant le potentiel de bouleverser l’image que construit l’Occident de l’Orient, le Web 2.0 actualise aussi l’Orientalisme visuel sous de nouveaux modes de production du savoir.

Flash Photography Enhancement via Intrinsic Relighting

We enhance photographs shot in dark environments by combining a picture taken with the available light and one taken with the flash. We preserve the ambiance of the original lighting and insert the sharpness from the flash image. We use the bilateral filter to decompose the images into detail and large scale. We reconstruct the image using the large scale of the available lighting and the detail of the flash. We detect and correct flash shadows. This combines the advantages of available illumination and flash photography.

Fundación Manuel H.

El proyecto “A través del lente de Manuel H.” plantea diseñar una Fundación cuya misión es fortalecer y reconstruir la memoria de Bogotá a partir de los relatos históricos expresados en las imágenes capturadas por el Maestro Manuel H entre 1946 y 2009. Se trabajará dicho fortalecimiento a partir de tres líneas de productos que se desarrollarán durante los seis primeros años de existencia de la Fundación. Las líneas de servicios que se plantean desarrollar inicialmente, hacen referencia a exposiciones innovadoras utilizando los nuevos conceptos de las artes visuales, actividades académicas y proyectos de responsabilidad social enfocados a la fotografía, las temáticas de la colección y al Maestro Manuel H.

fotografía y métodos históricos : dos textos para un debate = Photography and historical Methodology : two text for a debat.

La presente obra bilingüe (castellano e inglés) a través de sus dos textos pretende servir como punto de partida para el desarrollo de un debate sobre la fotografía y sus relaciones con la historia. El objetivo del libro es establecer puntos de reflexión sobre metodología de la historia frente a las dimensiones culturales, estéticas y tecnológicas del fenómeno fotográfico. Se divide el libro en dos capítulos: 1. De la 'Fotohistoria' a la Historia con la fotografía. 2. Imágenes contaminadas. (La fotografía en la Historia del arte).

Declines of Aerial Insectivores in North America Follow a Geographic Gradient

North American birds that feed on aerial insects are experiencing widespread population declines. An analysis of the North American Breeding Bird Survey trend estimates for 1966 to 2006 suggests that declines in this guild are significantly stronger than in passerines in general. The pattern of decline also shows a striking geographical gradient, with aerial insectivore declines becoming more prevalent towards the northeast of North America. Declines are also more acute in species that migrate long distances compared to those that migrate short distances. The declines become manifest, almost without exception, in the mid 1980s. The taxonomic breadth of these downward trends suggests that declines in aerial insectivore populations are linked to changes in populations of flying insects, and these changes might be indicative of underlying ecosystem changes.

Determining nugget: sill ratios of standardized variograms from aerial photographs to krige sparse soil data

Maps of kriged soil properties for precision agriculture are often based on a variogram estimated from too few data because the costs of sampling and analysis are often prohibitive. If the variogram has been computed by the usual method of moments, it is likely to be unstable when there are fewer than 100 data. The scale of variation in soil properties should be investigated prior to sampling by computing a variogram from ancillary data, such as an aerial photograph of the bare soil. If the sampling interval suggested by this is large in relation to the size of the field there will be too few data to estimate a reliable variogram for kriging. Standardized variograms from aerial photographs can be used with standardized soil data that are sparse, provided the data are spatially structured and the nugget:sill ratio is similar to that of a reliable variogram of the property. The problem remains of how to set this ratio in the absence of an accurate variogram. Several methods of estimating the nugget:sill ratio for selected soil properties are proposed and evaluated. Standardized variograms with nugget:sill ratios set by these methods are more similar to those computed from intensive soil data than are variograms computed from sparse soil data. The results of cross-validation and mapping show that the standardized variograms provide more accurate estimates, and preserve the main patterns of variation better than those computed from sparse data.
