Green Bean Yield and Path Analysis in Cowpea Landraces2016 •
Cowpea (Vigna unguiculata (L.) Walp.) is widely cultivated in northeast Brazil for production of both green grains and dry grains. Green grains are cowpea grains with a 60 to 70% moisture content that are very appreciated by the local people. The cultivation of cowpea in northeast Brazil is performed mostly using landraces and the low yields achieved in some areas of that region are generally attributed to the cultivation of less productive landraces. The objectives of this research were to identify the best landraces in terms of green bean yield and the characters that hold the most positive direct effects on this yield via path analysis. Twelve landraces of undetermined growth were evaluated in two experiments conducted in Mossoró, Brazil. The first experiment (E1) was sprinkler-irrigated and the second (E2) was conducted under rainfed conditions, but was irrigated whenever necessary. Pod yield and dimensions and green grains were evaluated, in addition to the main grain yield com...

The degree to which the maintenance of carbon (C) stocks and tree diversity can be jointly achieved in production landscapes is debated. C stocks in forests are decreased by logging before tree diversity is affected, while C stocks in monoculture tree plantations increase, but diversity does not. Agroforestry can break this hysteresis pattern, relevant for policies in search of synergy. We compared total C stocks and tree diversity among degraded forest, complex cacao/fruit tree agroforests, simple shade-tree cacao agroforestry, monoculture cacao, and annual crops in the Konawe District, Southeast Sulawesi, Indonesia. We evaluated farmer tree preferences and the utility value of the system for 40 farmers (male and female). The highest tree diversity (Shannon–Wiener H index 2.36) and C stocks (282 Mg C ha−1) were found in degraded forest, followed by cacao-based agroforestry systems (H index ranged from 0.58–0.93 with C stocks of 75–89 Mg ha−1). Male farmers selected timber and fruit...

Diagnostico de necesidades de formacion en etica de la investigacion bioetica e integridad cientifica en Colombia
Diagnostico de necesidades de formacion en etica de la investigacion bioetica e integridad cientifica en Ingenierias2021 •
El tema de este capítulo está relacionado con las necesidades de formación en ética de la investigación, bioética e integridad científica (EIBIC) en los procesos de investigación en ingenierías. El objetivo es establecer las necesidades de formación en ética de la investigación, bioética e integridad científica en ingeniería; en cuanto a la metodología, el análisis de resultados se realizó de manera particular por medio de matrices de registro y análisis, para luego esquematizarlas a través de mapas conceptuales y niveles de criticidad. Como conclusión, se evidencia el conocimiento y énfasis en ética de la investigación (EI), mas no en bioética (B) ni integridad científica (IC), cuya característica transversal es el desconocimiento en B y la concepción confusa de lo que es la IC. La recomendación es que, dada la fragmentación de las tres dimensiones (EIBIC), se exige la formulación de un proyecto curricular que integre un plan de formación para todos los actores que intervienen en la investigación, con énfasis en una visión holística de EIBIC.
