Adoption and diffusion of no tillage practices in Southern Spain olive groves
No full textThis paper analyses the process of adoption of no tillage in South-eastern Spain’s olive groves. Olive tree groves in South-eastern Spain’s mountainous areas are subject to a high risk of soil erosion, which is the main environmental problem for this crop, and have to incur in high costs of soil conservation. This results in a greater difficulty to comply with the practices required to benefit from both the single payment and agri-environmental schemes. In many high-steeped areas, farmers have opted for non-tillage practices as an alternative to other conservation practices. Using our own data from a survey carried out in 2006 among 215 olive tree farmers from the Granada Province in Southern Spain regarding the adoption of soil conservation and management practices, we model the diffusion process of no tillage practices using several specifications (logistic, Gompertz and exponential). We also estimate an ordered probit model to analyse which socio-economic and institutional factors determine the adoption of no tillage. Our results show that 90% of farmers in the area of study perform no tillage with either localized (21%) or no localized (69%) application of weedicides. The diffusion process of no tillage has been very intense since the middle nineties, and has been based on the interactions among farmers in the area of study rather than in external factors such as EU policies or extension services. Among other relevant factors that positively affect the adoption of no tillage practices in general, such as farm size and irrigation, the probability of a farmer adopting no tillage with non-localized application of weedicides increases when there is a relative that will continue with the farming activity, what causes the farmer to incorporate long term effects in his farming decisions, when the farmer is only a manager or when he bought the farm rather than inherited it (i.e. on more professionalized farms), and with his educational level. These results confirm some findings from previous studies in other nearby areas.Spanish olive groves, soil erosion, no tillage, Crop Production/Industries, Land Economics/Use,

No full textDean J. Franco, Race, Rights & Recognition: Jewish American Literature since 1969
No full textDean J. Franco's book is divided into two sections and six chapters; there is also a long introduction and an epilogue. Each of the six chapters is ostensibly concerned with the works of a single author—“works” because Franco discusses short stories, essays, a memoir, and a play as well as novels. The authors are: Philip Roth (Portnoy's Complaint), Cynthia Ozick (various works but mainly “The Pagan Rabbi”), Allegra Goodman (Kaaterskill Falls), Lore Segal (Her First American), Tony Kushman (Ho..

La propuesta de contametría de Rafael Franco, desde el pensamiento complejo de Edgar Morin
No full textEste trabajo tiene como objetivo comprender la propuesta de Contametría del maestro Rafael Franco interpretándola a la luz de la teoría de la complejidad. Para ello se entendió el contexto que motivó al autor a plantear la teoría de la Contabilidad Integral y su tecnología la Contametría, también se estudió la teoría de la complejidad, desde Morin.
Se realizó bajo el enfoque cualitativo, siendo una investigación de tipo explicativa con la cual se caracterizó el pensamiento complejo de Edgar Morin por medio de la definición de un grupo de categorías que permitieron la identificación del pensamiento complejo en la propuesta contamétrica del maestro Rafael Franco.
Por dar un ejemplo, entre las categorías estudiadas se encuentra “La unión”, la cual, en el discurso de Morin se observa como necesaria para concebir procesos y ciencia, pues en la ausencia de esta existiría la simplificación e interacción entre los elementos; otra categoría es el “Orden/Desorden” orientado a comprender el caos del universo, ya que la ciencia tradicional
solo reconoce el pensamiento objetivo, generando así un orden científico. Por medio de estas y otras categorías, se logró identificar que estos elementos propios de la teoría de la complejidad, efectivamente se encuentran en la propuesta contamétrica objeto de estudio de este trabajo.Universidad Libre - Facultad de Ciencias económicas, administrativas y contables - Maestría en ContabilidadThis work aims to understand the proposal of Contametría of professor Rafael Franco interpreting it in the light of the theory of complexity. To this end, we understood the context that motivated the author to raise the theory of integral accounting and its technology Contametry, we also studied the theory of complexity by Morin.
It was carried out under the qualitative approach, being an explanatory type of research with which the complex thinking of Edgar Morin was characterized through the definition of a group of categories that allowed the identification of the complex thinking in the Contametric proposal of Professor Rafael Franco.
To give an example, among the categories studied is "Union", which in Morin's discourse is observed as necessary to conceive processes and science, since in the absence of this there would be simplification and interaction between the elements; another category is "Order/Disorder" oriented to understand the chaos of the universe, since traditional science only recognizes objective thinking, thus generating a scientific order. By means of these and other categories, it was possible to identify that these elements of complexity theory are indeed found in the Contametric proposal under study in this work
Low-Cost Laser-Based Localization System for Agricultural Machines
No full textThis paper describes the design and test of a low-cost localization system for agricultural applications, which determines a tractor position in fields up to 0.5 km with an uncertainty of about 1 m. The proposed system employs a standard unmodified laser head, which is commonly used for field leveling, plus a reference ground-fixed laser receiver and requires neither laser modulation nor expensive time-of-flight measurements of light beam
