Clustering and classifying images with local and global variability

A procedure for clustering and classifying images determined by three classification variables is presented. A measure of global variability based on the singular value decomposition of the image matrices, and two average measures of local variability based on spatial correlation and spatial changes. The performance of the procedure is compared using three different databases

Consideraciones wittgensteinianas a la estructura de la mecánica cuántica

A la hora de formalizar las propiedades de los sistemas cuánticos, la estructura lógica en que se fundaron tales formalizaciones ha resultado ''no-clásica" (Birkhoff y van Neumann, 1936, Jauch, 1973). La insistencia en utilizar los razonamientos y esquemas conceptuales clásicos para interpretar el mundo microfisico deviene traumáticamente paradójica. Este es el caso del "gato de Schrodinger" que pensado en términos tradicionales nos enfrenta a conclusiones tales como la que sostiene que en el "mundo" microfisico existen estados "extraños", que combinan estados tipo "gato vivo" con otros tipo "gato muerto"· El análisis de los sistemas cuánticos nos conducen a paradojal derivadas de su estructura lógica "no clásica" de la teoría

Integral formulation of comprehensive plan solid waste management of urban area of Santiago, Norte de Santander

La producción de desechos sólidos es muy superior al promedio establecido para el estrato socioeconómico del municipio, además los residuos recolectados sin normas o protocolos de seguridad ambiental son insuficientes, el objetivo principal al formular un plan de manejo de residuos sólidos del Municipio de Santiago – Norte de Santander es definir con ello estrategias de valorización, aprovechamiento y disposición final adecuada de los residuos sólidos orgánicos e inorgánicos, se persigue el establecimiento de una Política Municipal que involucre a actores como Administración Municipal, establecimientos educativos, organizaciones comunitarias y sus líderes, representantes de las diferentes entidades municipales de manera que se conforme un bloque donde se sensibilice, y se ponga en practica los programas y normatividad propuestos en el PGIRS, creando una cultura ambiental.Currently the amount of solid waste carried in landfill is far too high considering that a large percentage of waste are usable. The aim of this paper is to develop a waste management plan according to the problems encountered in Las Lunas’ residential complex, as the lack of conscience of the residents, the desegregation of waste and inadequate conditions has the storage site for different types of waste. From the diagnosis and the counterfoil DOFA, three programs were generated: managing environmentally surely; of awareness, environmental education and socialization and follow-up and control. On the other hand, usable residues are going to be managed by ASOAMBIENTAL and EMSERCHÍA and some chats of awareness are going to be given to the complex residents

After all, how many companies are there in this town?

Barueri é um municipio da Grande São Paulo, localizado a oeste da capital. A cidade oferece alíquotas diferenciadas para impostos a empresas que ali se instalam, tornando-se importante polo de atração industrial. Em virtude da oferta de tais benefícios, o município ficou repleto de empresas de papel, ou seja, empresas se estabelecem formalmente na cidade, mas não desenvolvem ali sua operação. Tal fato torna difícil a tarefa de identificar organizações cujas operações aconteçam efetivamente no município. O contato telefonico com uma empresa com sede em Barueri resulta, frequentemente, em tratar com um escritório de contabilidade que a representa, uma vez que a operação está em outros lugares. A Universidade Presbiteriana Mackenzie pretendeu produzir um trabalho de aproximação com empresas da região, em face dos planos de desenvolvimento estabelecidos para o câmpus Tamboré, localizado em Barueri. Desta feita, era imprescindível definir universo e plano amostral com empresas cujas operações ocorressem na circunvizinhança, com vistas a estabelecer programas de parcerias. Deu-se, então, o desafio de encontrar quais organizações estavam efetivamente no municipio, uma vez que as empresas de papel não interessavam para os propósitos de desenvolvimento do campus. Como encontrá-las?Barueri is a small country town, located to the west of São Paulo City. The town offers tax exemptions to companies that set up business there, becoming an important industrial area and cluster. As a consequence, Barueri has filled up with paper companies, that is, companies that exist only for formal burocratic purposes, but which do not really conduct their operations there. The task of identifying which companies really conduct their operations in the town is difficult. Frequently, a contact with a company with headquarters in Barueri results in dealing with a professional accounting office professional which represents it, with the organization effectively being located outside the town. The Presbyterian Mackenzie University intended to establish relationships with companies of the region, considering the plans of development for the Tamboré Campus, located in Barueri. Consequently, it was essential to define a universe and a sample of companies whose operations occurred in the surrounding area of the Campus in order to establish partnership programs. It was therefore faced with the challenge of finding which companies were effectively located in Barueri, since paper companies have no interest in the development of the campus. How to find them

Social, environmental, and COVID-19 pandemic-related effects on women's food security and health in Honduras

The COVID-19 pandemic has disproportionally affected women in Honduras in terms of loss of employment and income opportunities, access to healthcare services, and increased poverty and food insecurity. The pre-pandemic gender inequalities in Honduras have resulted in harsher conditions for women since the onset of the pandemic. Early reports indicate that women have lost employment and incomes and have been burdened by other effects of the pandemic, such as more household work, childcare activities, and home schooling. Marginal groups such as indigenous women face greater challenges because of the structural and systemic inequalities which have existed for a long time. The impact of the COVID-19 pandemic has also differed across geographic areas and between rural and urban settings. In addition to the pandemic, the economic outlook for women in Honduras has worsened since the impact of Hurricanes Eta and Iota in November 2020, which displaced over a million people. The agricultural sector was devastated, and infrastructure was severely damaged. The recovery efforts have been slow because of the COVID-19 pandemic. This paper explores the root causes of gender inequalities and how it affects women’s food security and health

Sistematización de una experiencia docente del área rural en institución educativa pública del Municipio de Quinchía. Risaralda/Colombia

La relevancia de sistematizar las experiencias docentes, radica en los resultados obtenidos por los estudiantes de Básica Primaria, especialmente el grado quinto, en pruebas nacionales e internacionales en el área de ciencias. En las pruebas nacionales los resultados reflejan que de cada tres estudiantes uno apenas logra reconocer y diferenciar fenómenos del entorno cotidiano y construir explicaciones sencillas sobre estos. También se evidencia que de cada cinco estudiantes dos no logran reconocer y diferenciar fenómenos desde las diferencias de cantidad y calidad, relacionar fenómenos según criterios de causalidad, inclusión, exclusión y correlación, de esta forma, se estaría haciendo alusión a que los estudiantes sólo son capaces de observar e identificar los fenómenos pero no están en la capacidad de explicarlo haciendo uso de habilidades de pensamiento más científicas como la indagación, la explicación basada en conceptos científicos

Caracterización del patrón de caminar en niños de 6 años, de una institución educativa en sector semirural en Pereira

Una vez que entendemos el patrón de caminar como un acto que acompaña al ser humano a lo largo de su vida y que puede incidir permanentemente en su cotidianidad, a partir de los postulados de Muñoz, se hace pertinente estudiar desde la pedagogía infantil el patrón de caminar como un elemento indispensable de la formación en la población infantil. Cabe señalar la necesidad de efectuar este proyecto en la medida que el caminar es una experiencia humana por excelencia que hace parte de la evolución, que viene de los procesos de transformación no solamente individual sino social, porque no caminamos igual que nadie, es decir que cada persona en el mundo camina diferente pero se adoptan los modelos de las condiciones geográficas y sociales a que pertenece cada persona. Al respecto Peralta propone que tantas formas de caminar hay, como personas en el mundo van, esto incide en que tantas personas van caminando y piensan distinto, por lo tanto el derecho a caminar se constituye desde Pavía como una de las expresiones de movimiento más auténtica y que pueden llegar a influir en el aprendizaje y la forma de actuar de las personas
