The arrival of biofuels companies in the Chira Valley, Piura, Peru, in order to produce ethanol on sugarcane cultivation, intensified the agricultural use of land and water in the mid-2000s. This article analyzes the ecological, political and social transformations that biofuels production brought about in the valley. For that purpose the paper describes the role of the state in promoting biofuels and the concomitant land and water-grabbing processes in the valley. It also explores the consequences it had for local communities and medium-sized and small farmers. Ethanol production in the Chira valley produced a profound space transformation because land and water-grabbing processes for biofuels reinforced social inequalities. Information for this article was gathered from primary and secondarysources. This is a qualitative research. Eighteen interviews were conducted in Piura and Lima.

With the rising influence of digitalization and its immense penetration intoeven everyday life, the last decade of the 20th Century addressed to a critical threshold in the successive transformation process of the spatiality in its long-term run. The advanced digital technologies of ubiquitous computing and generative design, as well as the invention of smart materials in late 90’s (particularly the nano-technological materials that emerged as the programmable matters with their ability to evolve continously) have all provoked the fluid characteristics of spatiality, and strengthen the transformative capacities of the architectural space through the emergence of computer-augmented territories. Additionally, while they are becoming as the body extensions, the advent of novel apparatuses and gadgets further enhanced the inte- gration of the corporal and incorporal bodies with the...

This article describes the fundamentals of digital image digital processing using a free-access, web user interface called Octave-Online. This interface is part of the GNU operating system software applications, as well as it is known as the equivalent of Matlab in free versión; for this reason, this tool was chosen in order to give a practical approach to the use of ten basic techniques of spatial processing of digital images. To do this, we started by collecting 8 files with image contents in JPG and with different characteristics such as high and low contrast, high and low frequency, shades of gray, and intensity of colors, to put the proposed processing techniques into practice. Subsequently, some guidelines were provided for access, upload of JPG files, creation of * .m extension files, and knowledge of certain tools offered by the Octave-Online web user in...

Studies indicate that air pollutant concentrations affect human health. Especially, Fine Particulate Matter (PM2.5) is the most dangerous pollutant because this is related to cardiovascular and respiratory diseases, among others. Therefore, governments must monitor and control pollutant concentrations. To this end, many of them have implemented Air quality monitoring (AQM) networks. However, AQM stations are usually spatially sparse due to their high costs in implementation and maintenance, leaving large áreas without a measure of pollution. Numerical models based on the simulation of diffusion and reaction process of air pollutants have been proposed to infer their spatial distribution. However, these models often require an extensive inventory of data and variables, as well as high-end computing hardware. In this research, we propose two deep learning models. The first is a generative...

The architecture, engineering, construction, and operation (AECO) industry has brought transformations within the field. Despite the changes, traditional teaching methods such as analyzing two-dimensional plans and models are still being used in training processes, which do not effectively promote the development of spatial skills. In this context, augmented reality (AR) can be used as a tool to translate two-dimensional information into three-dimensional space. Thus, the present study explores the use of the VT-Platform AR tool to develop and reinforce spatial skills among undergraduate civil engineering students. The study follows a quantita-tive approach with a descriptive scope and an experimental design. Students in the sanitary engineering subject were divided into two groups: an experimental group and a control group. A short-term teaching-learning methodology was proposed for the...

This study identifies the adverse context for the reproduction of peri-urban family farming in Cuautlancingo, Puebla, through a case study that analyzes the territorial transformations shaping its peri-urban area. The analysis shows that these transformations reflect a complex process of spatial, socioeconomic, and cultural reconfiguration, underpinned by dynamics of accumulation by dispossession (AxD). Urban expansion, neoliberal policies, and real-estate speculation have displaced traditional agricultural practices, fostering land-tenure changes and legalization mechanisms of ejido property that integrate agricultural land into the real-estate market. Among the findings, more than 40 % of agricultural areas were lost between 2005 and 2021 due to growth in the industrial and housing sectors. Nevertheless, agriculture persists as a sociocultural practice and a source of local identity. T...

Morris water maze (MWM) test is widely used to evaluate the learning and memory deficits in rodents. Image processing and pattern recognition can be used to analyse videos and recognize automatically the tracking in MWM. There are several commercial and free access software that allows analyzing the behavioral tasks although they also have limitations such as automation, cost, user intervention among other things. The aim of this paper was to develop a new image processing technique to automatically analyse the track of the rat in the MWM, which we called RatsTrack. The MWM test was performed with an animal model for Alzheimer, and the videos were recorded to measure the distance, time, and speed. The segmentation method based on the projection of the video frames was made for pool identification, eliminating the rat, while conserving the shape of the pool. Then, the Hough transformation...

Las distintas actividades económicas y de subsistencia responden a los cambios o dinámicas que se forman en cada contexto. Actualmente, la globalización aparece como uno de los factores principales de influencia sobre las actividades económicas. Es decir, es innegable que todas las actividades económicas transforman sus procesos inducidas por ese fenómeno, en la medida que las distintas regiones han requerido integrarse al proceso. En ese sentido, los Estados, al procurar sumarse al contexto global han contribuido a la configuración del nuevo escenario comercial. Esto implica que muchas sociedades con costumbres distintas y formas de vida diferentes han tenido que adecuarse a una nueva dinámica comercial, donde las exportaciones son el principal nexo hacia el mercado global.Es así que el presente trabajo tiene como principal objetivo identificar y analizar las dinámicas espacia...

When analyzing the evolution of development and social changes in the population of the districts of San Mateo de Otao and Callahuanca - Huarochirí 2017, we find a series of transformations, mainly in agriculture, originally from sustenance, to agriculture oriented towards marketing, for the internal and external market. This despite the shortage of water for irrigation, the abandonment of villages and annexes that are above 3,000 meters above sea level and the migration of the young population, detracting from the local workforce. We also verify the lack of attention to cultural heritage and education, in terms of health, primary care prevails. Finally, to encourage the process of development and changes in the social components of San Mateo de Otao and Callahuanca, it is necessary to implement spatial equity policies and socio-economic actions for all peoples and annexes, with adequat...

Los chachapoyas han sido percibidos como una entidad cultural periférica en relación con las otras sociedades de los Andes. Queda claro que la cultura material relacionada con los chachapoyas fue desarrollada antes de 1000 d.C., pero lo que no queda claro es si tuvo un carácter uniforme a nivel regional. En los Andes prehispánicos la centralización urbana y la presencia de arquitectura con una separación clara de espacios se han utilizado como evidencias de las transformaciones sociales y políticas. Por otra parte, es probable que las conquistas de los inkas y los españoles hayan resultado en cambios radicales en las relaciones de trabajo, la economía y las prácticas religiosas de los grupos étnicos conquistados.En la actualidad hay pocas investigaciones que hayan estudiado cómo las prácticas sociales cambiaron bajo diferentes regímenes. En este estudio se emplea una ...

In the article, the capability of the space category is considered as one of the main conditions of the matter's existence. We are referring to the length, width and height in their 3D unity. In order to increase the effectiveness of children's physical rehabilitation from a methodological point of view, we proposed to consider physical space as a conditional four-dimensional substance, including еhe subjective aspect of a specific motoric play situation perception of a child and a rehabilitation teacher. During the physical rehabilitation classes for children with musculoskeletal system disorders, after many years of practice, it was noticed that spatial parameters can be purposefully controlled to improve the correction efficiency of various motoric disorders. The authors propose to consider as a special phenomenon the corrective modelling of the internal hall architecture to solve th...

A mediados de los años 2000, la llegada de empresas de biocombustibles al valle del Chira en Piura, Perú, para producir etanol usando como base el cultivo de la caña de azúcar intensificó el uso agrícola de la tierra y los recursos hídricos. En este artículo analizo las transformaciones ecológicas, políticas y sociales que la producción de biocombustibles generó en este valle. Para ello, describo el rol que tuvo el Estado en la promoción de biocombustibles y los procesos concomitantes de acumulación de tierra y agua en el valle, y exploro las consecuencias que ello tuvo para algunas comunidades y pequeños y medianos agricultores locales. La producción de etanol en el valle del Chira significó una profunda transformación en el espacio, debido a que los procesos de acumulación de tierra y agua para los biocombustibles reforzaron las desigualdades sociales. La informació...

El objetivo de la investigación es analizar las percepciones comunitarias sobre las transformaciones territoriales y los impactos en la calidad de vida derivados de la iniciativa de desarrollo turístico Surf City en el municipio de La Libertad Costa (El Salvador). Para lograr esto, se utilizó una metodología cualitativa con entrevistas en profundidad a actores clave, incluyendo vendedores informales de playa (60% mujeres), líderes comunitarios y pequeños empresarios de las cuatro comunidades afectadas (El Majahual, El Sunzal, El Palmarcito y El Zonte). Los hallazgos dan cuenta de tres procesos socioespaciales interconectados. En primer lugar, la gentrificación espacial se manifiesta mediante la privatización del frente costero, el desarrollo de bienes raíces de lujo y una infraestructura que prioriza a los turistas extranjeros sobre las necesidades locales. En segundo lugar, el ...

No final da década de 1990, surgiram análises de processos de gentrificação em vários centros históricos da América Latina. Desde então, têm sido produzidos estudos de caso na região que utilizam este anglicismo para tentar explicar um conjunto de transformações socio-espaciais que, por sua vez, acompanham os processos de patrimonialização dos centros históricos. Estes trabalhos caracterizam-se por uma utilização heterogénea e, em alguns casos, até ambígua do conceito. Perante esta situação, o objetivo deste artigo é propor um conjunto de chaves analíticas que permitam o estudo da gentrificação nos centros históricos a partir do quadro do discurso geográfico-crítico. Para o efeito, são expostas as bases teóricas do discurso crítico em relação à teoria da produção do espaço, a partir das quais se delimitam as categorias de centro histórico e gentrifi...

El presente trabajo tiene como objetivo partir de consideraciones teórico conceptuales de la geografía política y económica que buscan dar una explicación otra a la disciplina y práctica de la logística en el ámbito comercial internacional. A través de una revisión histórico-documental, la discusión trata de resaltar el papel de un proceso conocido como “revolución logística”, surgido tras la segunda posguerra y que empujó una serie de transformaciones que coadyuvaron a la producción de una espacialidad integrada bajo una razón logística en diferentes escalas geográficas. Además, busca dar cuenta del nexo existente entre el proceso de militarización global que se ha intensificado en los últimos años a partir de la reestructuración de la geografía del capitalismo neoliberal, conduciendo a la reconceptualización de la seguridad y a su ejercicio.
