Title A name given to the resource Calculo económico y diferenciación demográfica en economía campesinas: los casos del oriente antioqueño, Córdoba y Sucre Creator An entity primarily responsible for making the resource Mariano Arango Restrepo Description An account of the resource • Resumen: El presente artículo confronta algunas importantes teorías sobre las economías campesinas con los resultados de dos investigaciones realizados en las regiones campesinas del Oriente antioqueño, Córdoba y Sucre, donde se encuestaron respectivamente 616, 385 y 404 unidades de producción. Estas resultaron con más de un 800% del valor de su producción integrada al mercado e impregnadas por relaciones salariales, ante todo por razones estacionales, en todos los rangos de tamaño, pero sin que esto eliminara su condición de economías campesinas. A consecuencia de lo anterior, los productores toman sus decisiones económicas sobre el aumento de unos cultivos y reducción de otros con base en sus cuotas de ganancia y no de acuerdo con sus precios de costo. Esta forma de cálculo económico está condicionada por la diversificación de riesgos a través de policultivo, la ampliación de la explotación a medida que aumenta su tamaño y el compromiso de sólo una parte pequeña del patrimonio con el crédito adquirido. Asimismo, se encontró cierto grado de diferenciación demográfica en estas explotaciones campesinas. • Abstract: This article considers various theories about peasant economies in the light of two studies in the regions of Oriente antioqueño, Córdoba and Sucre. These studies found more than eighty percent of the value of production integrated into the market and salary oriented without vitiating the truly peasant nature of these economies. Producers were found to make decisions about future levels of production on the basis of relative profitability not on costs. To some extent this general finding has to be modified allow for diversification of risk, with lot size and with levels of indebtedness. There were also some important demographic factors.

Title A name given to the resource Critérios para transporte e utilização dos suínos na agricultura Creator An entity primarily responsible for making the resource Eloi Erhard Scherer Description An account of the resource A utilização do esterco de suínos como fonte de nutrientes para as plantas tem sido vista como a forma mais viável de sua reciclagem agrícola. O presente estudo teve como objetivo avaliar a economicidade do transporte e a utilização do esterco de suínos como fertilizante. No estudo, foram utilizadas análises de 98 amostras de dejetos suínos coletadas em esterqueiras da Região Oeste de Santa Catarina. Com base no teor médio de matéria seca e de nutrientes encontrados nas amostras analisadas, a distância máxima de transporte dos dejetos foi de 30km. Porém, quando se aumenta o teor de matéria seca dos dejetos de 3% para 6%, a distância de transporte aumenta de 30 para 84km, ampliando a área de abrangência de seu uso como fertilizante economicamente viável. A redução do volume de água adicionada aos dejetos suínos viabiliza, de forma econômica, o transporte e a reciclagem dos mesmos na agricultura.

Title A name given to the resource Entre lo formal y lo no formal: un análisis desde la formación permanente del profesorado Creator An entity primarily responsible for making the resource Iris Estévez, Alba Souto-Seijo, Mercedes González-Sanmamed, Verónica Iglesias Fustes Description An account of the resource Una de las características más relevantes de la sociedad actual es que el aprendizaje no se desarrolla de forma lineal ni en espacios concretos, por lo que no se puede limitar a los parámetros de la modalidad formal. Así, el presente estudio tiene como finalidad analizar la formación permanente de los docentes de educación primaria en el marco de la comunidad autónoma de Galicia. Concretamente se pretende determinar dónde se forma el profesorado, cuándo realiza las actividades formativas, qué modalidades formativas emplea y por qué decide formarse. Para ello se ha llevado a cabo una investigación de corte cuantitativo. La muestra está compuesta por 73 docentes de educación primaria. El instrumento de recogida de información ha sido un cuestionario de elaboración propia validado a través del juicio de expertos. Los datos fueron analizados con el paquete estadístico IBM SPSS Statistics (versión 25). Los resultados evidencian que el profesorado realiza un mayor número de actividades formales que no formales. En ambos casos el momento elegido está fuera del horario lectivo, pero se sitúa durante el curso académico, y la modalidad seleccionada es la presencial. Finalmente, las razones que llevan al profesorado a implicarse en ambos tipos de actividades formativas son de carácter intrínseco.

Title A name given to the resource El agua fluye hacia el turista Creator An entity primarily responsible for making the resource Grettel Navas Description An account of the resource La creciente demanda de agua potable para abastecer la industria hotelera en la costa pacífica costarricense ha llevado al sector turismo a buscar fuentes cada vez más alejadas, ocasionando tensión e incertidumbre en las comunidades locales por una futura escasez. Bajo un marco teórico de Ecología Política y Justicia Ambiental, este artículo caracteriza tres conflictos suscitados por el turismo residencial e inmobiliario en la provincia de Guanacaste, Costa Rica: Lorena (1998), Sardinal (2006) y Potrero (2014). En los tres casos, las comunidades utilizan la judicialización del conflicto como estrategia para asegurar su derecho al agua potable y a un ambiente sano. Se concluye que si bien hay un aparente éxito, los escenarios de conflictividad continúan latentes y se recomienda una revisión profunda del modelo turístico que se está implementando. Las revisiones propuestas incluyen: la participación de las comunidades locales en la toma de decisiones relacionadas al agua, información libre y previa con los actores locales y una clasificación sobre los usos del agua con criterios y prioridades.

Title A name given to the resource Agricultura Familiar e Desenvolvimento Paranaense entre 1996 e 2006 Creator An entity primarily responsible for making the resource Christian Luiz da Silva, Weimar Freire da Rocha Jr., Caio Cezar Zerbato Description An account of the resource A agricultura familiar é relevante para o processo de modernização tecnológica do agronegócio brasileiro e, principalmente, tem fortes laços regionais. Dessa forma, a agricultura familiar é amortecedora das crises no setor agrícola e agente de desenvolvimento local, mas questiona-se, com este trabalho, se a agricultura familiar constitui-se moderna e competitiva, potencializando o desenvolvimento local sustentável e a melhoria da qualidade de vida no campo. O objetivo geral deste trabalho foi avaliar se as regiões geográficas paranaenses com um modelo agrícola predominante pautado na agricultura familiar possuem melhores indicadores sociais e econômicos. Trata-se de um método de pesquisa aplicado, com estatística descritiva e de correlação entre indicadores socioeconômicos e dos dados do censo Agropecuário de 1995/1996 e 2006.  Como resultado observou-se que onde a agricultura familiar é predominante verifica-se melhores indicadores econômicos e sociais. Ainda, o estudo demonstrou como esse modo de produção caracteriza-se por ser o maior gerador de empregos no meio rural e promover a sustentabilidade ambiental na agricultura.

Title A name given to the resource Análise de coliformes fecais na água de policultivo de peixes integrados à suinocultura Creator An entity primarily responsible for making the resource Osmar Tomazelli Júnior, Jorge de Matos Casaca, Renato Dittrich Description An account of the resource Como a suinocultura está presente na maioria das pequenas propriedades rurais do Oeste Catarinense, criou-se um cenário favorável para a produção de peixes em policultivo com fertilização através de dejetos de suínos. Embora reconhecido por especialistas que este sistema de cultivo vem colaborar com a melhoria da qualidade ambiental, o produtor rural tem enfrentado críticas de que a piscicultura integrada à suinocultura estaria promovendo a contaminação dos riachos que recebem seus efluentes. O objetivo deste trabalho foi estudar a qualidade da água dos efluentes produzidos pela piscicultura com ênfase em indicadores de contaminação fecal. Durante dois anos foram monitorados 26 viveiros nos três modelos de aporte de dejetos: horizontal, vertical e variável, de um total de 161 viveiros no município de Chapecó. A concentração de coliformes fecais de até 1.000NMP/100ml nos efluentes ocorreu em 69,9%; 77,8% e 86,5% das 396 amostras analisadas nos modelos vertical, horizontal e variável, respectivamente. A concentração de até 4.000NMP/100ml ocorreu em pelo menos 88,5% das amostras analisadas, para os três modelos de aporte de dejetos. A legislação ambiental de Santa Catarina estabelece para os corpos receptores de efluentes o índice-limite de 1.000NMP/100ml de coliformes fecais em 80% ou mais de, pelo menos, cinco amostras mensais para águas de classe II e 4.000NMP/100ml para águas de classe III. Assim, a qualidade da água dos efluentes da piscicultura integrada à suinocultura analisada neste estudo está dentro dos limites tolerados segundo a legislação ambiental para os corpos receptores de classes II e III.

Title A name given to the resource Impact of Gastrointestinal In Vitro Digestion and Deficit Irrigation on Antioxidant Activity and Phenolic Content Bioaccessibility of “Manzanilla” Table Olives Creator An entity primarily responsible for making the resource Francisca Hernández, Lucía Sánchez-Rodríguez, Marina Cano-Lamadrid, Ángel A. Carbonell-Barrachina, Esther Sendra Description An account of the resource This was the first study investigating the polyphenol content, antioxidant potential, and polyphenol bioaccessibility after in vitro digestion of table olives grown using regulated deficit irrigation (RDI) treatments to save irrigation water. Two experiments were carried out: (i) experiment A, where RDI was applied during the pit hardening stage and (ii) experiment B, where RDI was applied during the rehydration stage. Only slight differences among irrigation treatments were observed in two antioxidant assays (ABTS+• and DPPH•) and on TPC for the soluble fraction after in vitro digestion. An average of 1 g gallic acid equivalents kg−1 of table olives were found after digestion. Approximately, 12% of the polyphenols of table olives were bioaccessible for human absorption. Saving water techniques influence neither the final polyphenol content and antioxidant potential of table olives nor the bioaccessibility of polyphenols. The consumption of 40 g of table olives will provide 40 mg of bioaccessible polyphenols able to provide associated health benefits (∼7% of the daily polyphenols intake recommendation).

Title A name given to the resource Supuestos epistemológicos y ontológicos presentes en la historia de la ecología Creator An entity primarily responsible for making the resource Carolina I. García Curilaf, Guillermo M. Denegri Description An account of the resource El propósito de este trabajo es mostrar los supuestos epistemológicos (empirista, racionalista y racioempirista) y ontológicos (individualista, holista y sistemista) presentes en la historia de la ecología, sobre la base de tres trabajos: Clements (1916), Gleason (1926) y Lindeman (1942). En este artículo analizamos el surgimiento de una posición moderada en la historia de la ecología. Defendemos la tesis de que a partir del trabajo publicado por Lindeman en 1942, comenzó a surgir en ecología un marco conceptual que toma implícitamente un enfoque ontológico sistemista y epistemológico racioempirista, y que se encuadra en los principios filosóficos desarrollados por Bunge. También mostramos las desventajas de implementar la epistemología racionalista y la epistemología empirista en la investigación ecológica, y las ventajas de utilizar la epistemología racioempirista. En la actualidad, los programas de investigación en ecología siguen alguno de estos tres principios ontológicos y epistemológicos.
