Alberto Hurtado University is a Jesuit university located in downtown Santiago. Established in 1997, the university was created from the merger of three separate institutes,Instituto Latinoamericano de Doctrina y Estudios Sociales , the Centro de Investigación, Desarrollo de la Educación , and the Fundación Educacional Roberto Bellarmino. The university is named after a famous Chilean Jesuit Saint, Father Alberto Hurtado. Wikipedia.

How do we practically deal with the waste produced by industrial processes? Until now this question has overwhelmingly been answered in one way: through the deployment of different kinds of waste management programs, technology-based top-down actions for waste whose ultimate aim is to make it disappear both physically by leaving it in fully enclosed dumps and politically by eliminating it as a matter of concern that must be dealt with. Due to the multiple setbacks that this approach has faced in terms of large spills and continual pollution, this paper states the need to consider a parallel set of practices that have been enacted, that is, the practice of caring for waste. Based on current developments in science and technology studies, care is presented as a way to deal with waste that, based on everyday practices and the inescapability of failure, proposes temporary and experimental ways to involve all the concerned parties in the search for alternative ways to live with our waste, in material, ethical and political terms. In order to explore the challenges that such an approach entails this paper will present some examples of caring for waste developed by the personnel of a large copper mine located in central Chile. © 2016, © The Author(s) 2016.

This article establishes a theoretical view and reflection with regards to inhabiting the barbarian city based on ethnographic evidence. Starting from the case of La Chimba in Santiago (Fondecyt [National Scientific and Technological Development Fund in Spanish] No. 1095083), the thesis of another form to inhabit where the chaos of the fragment represents the unity for the shelter of its inhabitants, is developed. This article emphasizes that the urban fact, as a social reality, owes its possibility to exist to these physical and symbolic border territories. To look back at the barbarian city is to admit that our cities have been made in these mirror games: between what is desired and denied, the center of power and what is outside this power. And the evidence that no urban reality exists, that it does not arise in this historically built tension. The challenge happens to be decoding these historical and urban processes that, not wanting to engage in an essentialist debate makes the barbarian city a landscape of otherness of memories and sovereignties, in permanent motion and dispute with the city itself, the city of the center of power and hegemony.

This article analyzes changes in the product mix by Chilean manufacturing plants in the period 1996-2003. Three quarters of the surviving plants changed the set of products produced and more than three quarters of the exporting plants changed the mix of products they exported during the sample period. Plants that changed their product mix contributed 85% of the aggregate growth in real sales of surviving plants between 1996 and 2003. Finally, and in contrast to the US evidence, there is a negative correlation between revenue per product and the number of products. Apart from this, new evidence consistent with recent models of multi-product heterogeneous firms and trade is provided. © 2012 Copyright Taylor and Francis Group, LLC. Source

Satellite image time series (SITS) provide spectral-temporal features that describe phenological changes in vegetation over the growing season, which is expected to facilitate the classification of crop types. While most SITS-based crop type classifications were focused on NDVI (normalized difference vegetation index) temporal profiles, less attention has been paid to using the complete image spectral resolution of the time series. In this work we assessed different approaches to SITS-based classification of four major fruit-tree crops in the Maipo Valley, central Chile, during the 2013-14 growing season. Wecompared four feature sets froma time series comprised of eight cloud-free Landsat-8 images: the full-band SITS, theNDVI andNDWI (normalized differencewater index) temporal profiles, and an image stackwith all the feature sets combined. State-of-the-art classifiers (linear discriminant analysis, LDA; random forest; and support vector machine) were applied on each feature set at different training sample sizes (N=100, 200, 400, 800 and 2291 fields), and classification results were assessed by cross-validation of the misclassification error rate (MER). For all the feature sets overall results were good (MERs = 0.21) although substantially improved classification accuracies were achieved when the full-band SITS was employed (MER 0.14-0.05). Classifications applied on the NDVI temporal profile consistently had the worst performance. For a sample size of 200 fields, LDA using the full-band SITS of image dates 1, 3, 6 and 8 produced the best tradeoff between the number of images and classification accuracy (MER = 0.06), being the green, red, blue and SWIR (short-wave infrared) bands of image date 1 (acquired at the early greenup stage) the most relevant for crop type discrimination. Our results show the importance of considering the complete image spectral resolution for SITS-based crop type classifications as the commonly usedNDVI temporal profile and their red and near infrared bands were not found the most significant to discriminate the crop types of interest. Furthermore, in light of the good results obtained, the methodology used here might be transferred to similar agricultural lands cultivated with the same crop types, thus providing a reliable and relatively efficient methodology for creating and updating crop inventories. © 2015 Elsevier Inc.

The concept of assemblages has gained an important degree of momentum in urban studies claiming to offer a new ontology for understanding cities as emergent and fluid concatenations of multiple elements. Such a conception, however, has also been criticised in relation to its supposed failure to deal effectively with the issue of power and inequality in urban dynamics. This paper contributes to this on-going discussion by exploring in detail the way in which power was embedded in one particular case: a bus stop shelter located in front of the Biblioteca Nacional in Santiago, Chile. In so doing, it analyses the controversy arising when two large and complex urban assemblages share component/s that each of them claims as exclusive. This situation made necessary practices of co-ordination in which a hierarchy was established between the competing assemblages, involving important transformations in some of its components. © 2013 Urban Studies Journal Limited.
