Description
An account of the resource
As regiões do estado do Rio de Janeiro apresentam diferentes condições climáticas, de relevo, de estrutura fundiária, e foram marcadas por processos históricos de formação diferenciados. Disso resultam distintas dinâmicas produtivas regionais, em particular na agricultura. Com o uso de medidas de concentração, diversificação, especialização e localização, buscou-se caracterizar as diferenças regionais quanto à produção agropecuária do estado, considerando-se os segmentos familiar e não familiar. Foram observadas significativas diferenças regionais quanto aos índices calculados, e constatada a importância da agricultura familiar, principalmente nas regiões Noroeste, Centro e na Metropolitana, onde se destacam, respectivamente, as microrregiões Santo Antônio de Pádua, Nova Friburgo e Serrana. Como os melhores índices de diversificação encontram-se nessa agricultura, seu papel na diversificação da economia agrícola do estado tem sido marcante.

Resumo Este trabalho procurou elucidar uma dimensão institucional de análise da implementação do Programa Nacional de Alimentação Escolar (Pnae). A pesquisa foi de caráter interpretativo e descritivo, de abordagem qualitativa, e utilizou como estratégia o estudo dos casos dos municípios de Espera Feliz e Guaraciaba, estado de Minas Gerais. A pesquisa confirmou a tese de que as interações entre diferentes atores no processo de implementação do Pnae produz efeitos sobre o comportamento desses atores e, mais especificamente, permite a construção de regras que constrangem e habilitam suas ações, produzindo novos padrões de interações e condicionando a forma como o programa é implementado localmente. A análise institucional também revela que as interações entre os atores e o “jogo da implementação” implicam em mudanças institucionais que são inerentes à tentativa de aproximar o programa à realidade local.

Description
An account of the resource
Com o reconhecimento da agricultura familiar brasileira enquanto categoria social e produtiva a partir dos anos 90, diversos programas de políticas públicas foram formulados no sentido de garantir sua reprodução enquanto produtora de alimentos básicos para a alimentação, além da manutenção e ocupação do homem no campo. Diante disto, este texto tem como principal objetivo analisar a agricultura familiar nos municípios do chamado 'Circuito das Frutas' do estado de São Paulo em relação à importância ao acesso aos principais programas de políticas públicas que visam o fortalecimento desta agricultura. Uma vez que esta região se caracteriza pela presença marcante de agricultores familiares, foram analisados o Pronaf (Programa Nacional de Fortalecimento da Agricultura Familiar), o PAA (Programa de Aquisição de Alimentos) e o PNAE (Programa Nacional de Alimentação Escolar), programas que têm se constituído em instrumentos de valorização deste segmento da agricultura paulista. Percebeu-se que, diante do universo da agricultura familiar nos municípios estudados, ainda é pequena a participação dos mesmos nos programas analisados. Dentre os fatores que podem explicar tal fato, ressalta-se a falta de informações aos agricultores sobre os programas, mas, sobretudo, o baixo valor passível de ser auferido por agricultor.

Description
An account of the resource
O artigo tem como objetivo analisar o sistema sócio-produtivo da agricultura familiar nos assentamentos Bom Sucesso, Corixo, Jatobá, Katira, Nova Esperança, Rancho da Saudade e Sapiquá, localizados no município mato-grossense de Cáceres. A pesquisa foi realizada com 27 agricultores familiares e a coleta dos dados ocorreu no primeiro semestre de 2014 por meio de entrevista semiestruturada. A formação escolar dos agricultores familiares predominou-se em ensino fundamental incompleto, contraindo matrimônio e organizados em pequenas propriedades, utilizando mão de obra familiar nas atividades agropecuárias (policultura) em uma infraestrutura deficitária. Evidenciou-se a possibilidade de implementação das políticas públicas do Programa de Aquisição de Alimentos e do Programa Nacional de Alimentação Escolar devido à capacidade produtiva, a proximidade e existência de escolas e de comércio local. Para isso, os agricultores familiares precisam se organizar em associações/cooperativas e os poderes públicos intervir no espaço e promover ações sólidas de desenvolvimento territorial e da agricultura familiar.

Description
An account of the resource
Este trabajo analiza los restos de mamíferos hallados en los niveles Magdaleniense, Aziliense, Mesolítico y Calcolítico de la Cueva de La Fragua (Santoña, Cantabria). En el nivel Magdaleniense existe una economia dual centralizada en la caza del ciervo y la cabra. A partir del nivel Aziliense y sobre todo en el Mesolítico, a raíz del cambio climático, empieza a hacerse patente la diversificación de recursos con la relevancia que adquieren taxones como el corzo y el jabalí, además de restos de malacofauna terrestre y marina. Una zanja en época Calcolítica (datada a partir de los restos cerámicos en ella recogidos) corta parcialmente parte de los cuadros excavados. Aparecen restos de animales domésticos. Esta zanja debió realizarse con fines sepulcrales a tenor de los retos humanos en ella encontrados. Gran parte de los restos muestran trazas antrópicas, huellas de alteraciones naturales y actividades de carnívoros y roedores que se han estudiado en un detallado análisis tafonómico. Además, gracias a un Sistema de Información Geográfica (SIG) que se ha aplicado al análisis arqueozoológico de esta cueva se ha podido observar de una manera muy gráfica la distribución de cada uno de los restos en los diferentes niveles, lo cual ha permitido avanzar en el conocimiento de las unidades sociales de consumo y de los diversos pobladores que ocuparon esta cueva en las distintas etapas.

Description
An account of the resource
Los estudios de comunidades de zooplancton son de gran importancia para la biología, ecología y conservación del ecosistema marino. Sin embargo, estas investigaciones implican un proceso de alto costo en términos de tiempo y esfuerzo, requiriendo personal entrenado para la identificación, conteo y medición de numerosos grupos taxonómicos, así como para la estimación de biomasa. Actualmente, existe un creciente interés por la implementación de nuevas técnicas que permitan automatizar los análisis, incorporando tecnología informática aplicada al examen automático de imágenes digitalizadas. En este trabajo se revisa el estado del conocimiento de algunas metodologías, basadas en el estudio de imágenes digitalizadas de zooplancton. Se presenta una descripción general de los métodos conocidos, tales como ZooScan-ZooProcess y Zoolmage, se analizan sus resultados para la identificación de distintos zooplancteres, se comparan con el método tradicional y se hacen propuestas para mejorar su aplicación. Adicionalmente, se resumen las experiencias con estos sistemas en el análisis de patrones de variabilidad espacial y temporal de la comunidad zooplanctónica, basados en el espectro de tamaño y pruebas para la estimación de biomasa de zooplancton. Finalmente, se elabora un listado de capacidades y limitaciones registradas en la bibliografía reciente, y se discute sobre las perspectivas de desarrollo y aplicación que ofrece esta metodología para la comunidad científica en Latinoamérica.

El Proyecto Estratégico de Seguridad Alimentaria (PESA) es uno de los programas que obedece a la política pública de seguridad alimentaria en zonas rurales marginadas. Cada año se le destina mayor presupuesto y cobertura, lo que sugiere que produce grandes resultados e impactos. Al utilizar el enfoque de política basada en evidencias en el Estado de Oaxaca, México, a través de una revisión sistemática, se encontró que no existen las evidencias suficientes que justifiquen el monto invertido en el programa, y que el sistema de seguimiento y evaluación del programa solamente pone énfasis en los procesos. Debido a la falta de una línea base e indicadores claros no es posible conocer en qué medida se han cumplido sus objetivos.

Description
An account of the resource
In 2020, Indonesia experienced a pandemic known as the Corona Virus or Covid-19. The government-imposed social distancing rules affect Indonesian society for teaching and learning activities at the university. Governments impose rules on online learning systems. The online learning system provides convenience, but on the other hand, there are adverse impacts for some students, one of which has a mental workload. The study aims to measure and analyze student mental workloads using the Rating Scale Mental Effort (RSME) method. The number of respondents was 111 students. The mental workload measured is a quantitative learning system that is quantitative with the delivery of the material directly (Synchronous) and the delivery of the material using the recorded video in advance (Asynchronous). The indicators of mental work effort are workload, work difficulties, job satisfaction, mental effort, anxiety, and work fatigue. The measurement results show that the RSME value of the workload indicator and the work difficulties between the online learning methods are significantly different. Mental workloads, technical difficulties, work mental ventures, work anxieties and work fatigue when online learning is high enough on the learning system using Synchronous, with a value of 93.27; 94.5; 94.27; and 96.54. However, for job satisfaction, students are more satisfied learning by using video recording than Synchronous, i.e., several 79.61. The results show that the recommended online learning method is with video recording.

An account of the resource
Se analizó la producción científica de los investigadores de la Facultad de Ciencias Agrarias (FCA) de la Universidad Nacional de Cuyo, Argentina, con el fin de contar con datos bibliométricos en el área de Ciencia y Técnica. Del análisis de 100 proyectos de investigación financiados por la Secretaría de Ciencia y Técnica de la Universidad Nacional de Cuyo se desprende que el 66% de los proyectos presentan producción de artículos científicos, de los artículos publicados el 46% se hizo en revistas con factor de impacto (FI). Las subdisciplinas en las cuales hubo más producción fueron las Ciencias Biológicas (Botánica, Ecología, Fisiología, Genética, Bioquímica, Biología Molecular) (20%) y Producción Vegetal (17%). El análisis de la producción de artículos científicos en la base de datos Scopus muestra una baja producción científica entre los años 1996 y 2000 y un incremento importante y sostenido de la producción desde el año 2001 en adelante. Este incremento se puede explicar en parte por la radicación, a partir del año 2000, de investigadores en la FCA que estaban trabajando en otras Universidades Nacionales o en el extranjero y por la producción de investigadores que forman parte de institutos del CONICET.

Description
An account of the resource
Las Pteridófitas de Chile continental están representadas por 116 especies nativas (43 géneros, 20 familias), y en Argentina continental por 346 (86 géneros, 27 familias). Ambos países comparten 89 especies (41 géneros, 20 familias). La menor diversidad pteridofítica y el mayor endemismo en Chile (11,2 %) que en Argentina (3,5 %) están relacionados probablemente con extinciones históricas y su actual aislamiento geoclimático. Sin embargo, se destaca que el endemismo en los helechos es cinco a seis veces menor que en Angiospermas. Los géneros con más especies en Argentina son Thelypteris (34), Asplenium (32), Cheilanthes (21), Blechnum (19) e Hymenophyllum (16). Los dos últimos también son los más diversificados en Chile (Hymenophyllum, 18 y Blechnum, 10). En la región estudiada la diversidad muestra incrementos latitudinales opuestos, concentrándose en tres centros, dos subtropicales en el noroeste y noreste de Argentina y uno templado-lluvioso en el sur argentino-chileno alrededor de los 40º latitud sur. Los tres centros de diversidad concentran el 93 % de las especies y el 95 % de los endemismos, compartiendo pocas especies entre ellos. En los centros subtropicales las familias Aspleniaceae, Polypodiaceae, Pteridaceae, Thelypteridaceae y Selaginellaceae son sus componentes más importantes, y comparten un gran número de especies con Bolivia y Brasil, respectivamente. El centro templado sur tiene una menor diversidad pteridofítica, pero se hallan en él mayor cantidad de endemismos (77 %) que en los centros subtropicales, a consecuencia de un fuerte aislamiento. Sin embargo, presenta altos índices de similitud e intercambio florístico entre ambas vertientes de Los Andes. Allí las Blechnaceae y Hymenophyllaceae son las familias mejor representadas. Los taxa que presentan una distribución disyunta encontrándose en los tres centros de diversidad, nos indican que la pteridoflora del Cono Sur fue históricamente más extensa y continua, y que sus límites han retrocedido a causa de los impactantes cambios climáticos y geomorfológicos que sucedieron durante el Terciario y el Pleistoceno.The pteridophytes are represented by 116 native species (43 genera/20 families) in continental Chile, and by 346 native species (86 genera/27 families) in continental Argentina. Both countries share 89 species (41 genera/20 families). Lower pteridophyte diversity and the higher endemism in Chile (11.2 %) than in Argentina (3.5 %) are possibly related to historical extinctions and the actual geo-climatic isolation. However, the endemism in pteridophytes is five to six times lower than in angiosperms. The richest Argentinean genera are Thelypteris (34 species), Asplenium (32), Cheilanthes (21), Blechnum (19) and Hymenophyllum (16). The last two genera are also the most numerous in Chile (Hymenophyllum 18 species and Blechnum 10). In the two countries, pteridophyte diversity shows opposite latitudinal trends, with high species richness in three centers: two subtropical humid centers in northwestern and northeastern Argentina, and a temperate humid center in southern Chile and Argentina around 40º S. The three centers concentrate 93 % of the species and 95 % of the endemisms, sharing few species. In the subtropical centers, the families Aspleniaceae, Polypodiaceae, Pteridaceae, Thelypteridaceae and Selaginellaceae are the main components and share a large number of species with Bolivia and Brazil, respectively. The southern temperate center has a lower pteridophyte diversity, but a larger number of endemisms (77 %) than the northern subtropical centers. However, adjacent regions of Chile and Argentina within the temperate center have high similarity and maintain a strong floristic interchange. Blechnaceae and Hymenophyllaceae are the most common families. Taxa with disjunct distribution patterns and with presence in the three centers indicate that the pteridophyte flora had a wider and continuous distribution in the past, and that their limits have receded as a consequence of the strong climatic and geomorphologic changes during the Tertiary and the Pleistocene.
