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,

Three-dimensional spectral measurements of paint samples using optical coherence tomography
No full textIn this study, we describe a method for measuring the spectral reflectance of a paint layer at both the surface and in the volume of the paint layers. We first present a fringes model which illustrates the possibilities for spectral reconstruction using a Short-Time-Fourier-Transform algorithm. We investigate the remaing percentage errors and identified that there is a strong fluctuation along the wavelength range of the spectrometer. Then, we demonstrate the validity of our approach experimentally by measuring the spectral reflectance of a paint layer using a custom-made visible light optical coherence tomography system. There, we reconstruct the spectral reflectance of a paint layer by probing the surface and a depth range below the surface. Finally, we show the importance to include a wavelength sensitive correction in the reconstruction for taking into account the spectral shape of the light in the reference path of the interferometer. This work is part of the Down To The Ground project, in which the results of the OCT inspection will be used directly by a consortium of technical art historians and conservators.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Structural Integrity & Composite
Landscape simplification increases Bactrocera oleae abundance in olive groves: adult population dynamics in different land uses
No full textBactrocera oleae is the main pest in olive groves, and its management requires a sustainable perspective to reduce the use of
chemical products. Landscape context is being considered as an important driver of pest reduction, but results on B. oleae
show inconsistency to date. Most of landscape-pest control studies focus on the dynamics of the pests within the focal crop,
ignoring these dynamics in other land uses. Here we present a study in which we analyze the seasonal population dynamics
of the olive pest B. oleae in the most important land uses of a typical olive landscape in Portugal. We found that B. oleae is
present in all the land uses and the dynamics are very similar to those in the olive groves. However, the presence of these
land uses in the landscape did not display any increase in B. oleae abundance within the olive groves. In contrast, a landscape
mainly composed by olive groves increased the abundance of this pest. Importantly, more diverse landscapes surrounding
olive groves reduce the abundance of the olive fy. Based on these fndings, we can conclude that B. oleae is present in all
the land uses of the studied landscape but that this presence does not imply an increase of B. oleae in olive groves. Indeed,
other land uses can promote landscape diversifcation which is a driver of the reduction of B. oleae populations in olive
groves. We thus encourage olive stakeholders to increase landscape diversifcation around their farms by promoting/restoring other crops/habitat

Training through drama for work
No full textIl testo in inglese propone l’analisi di quattro personaggi - la Figliastra da Sei personaggi in cerca d’autore di Luigi Pirandello, Callimaco da La Mandragola di Niccolò Machiavelli, Thomas Becket da Assassinio nella cattedrale di T.S. Eliot e Portia da Il mercante di Venezia di William Shakespeare - per rispondere alla domanda chiave: “Quali spunti possiamo trarre da questi quattro personaggi per applicarli in ambito lavorativo?”
Prendendo spunto da un’ampia gamma di idee, da concetti di training e coaching, il testo propone una prospettiva innovativa sui temi dello sviluppo professionale e personale applicabili nel mondo del lavoro dove la performance - a volte comica, persino tragica - costituisce il fondamento di gran parte delle iniziative.
Le opere scelte appartenendo al canone teatrale europeo sono state già ampiamente analizzate. Eppure, rimangono una straordinaria fonte d’ispirazione e apprendimento. Le idee presentate nel testo costituiscono un punto di vista personale, quindi ogni altra interpretazione è egualmente possibile. Il testo va pertanto considerato come un “passo lungo il cammino” anziché una conclusione allo studio dei testi.
Il volume è corredato da una bibliografia selezionata e da un ampio glossario inglese-italiano, che copre la terminologia dei campi relativi: teatro, management e leadership, sviluppo professionale e personale.This book in English puts forward an analysis of four characters -The Stepdaughter from Six Characters in Search of an Author by Luigi Pirandello, Callimaco from The Mandragola by Niccolò Machiavelli, Thomas Becket from Murder in the Cathedral by T.S. Eliot, and Portia from The Merchant of Venice by William Shakespeare - in answer to the key question ‘What input can these four mavericks offer us as training for the workplace?’
Drawing on a rich pool of ideas, training and coaching concepts, it furnishes an innovative perspective on professional and personal development themes applicable to work where performance - sometimes comic, even tragic - forms the bedrock of most endeavours.
As part of the canon of European drama, the selected pieces have already undergone much inspection and yet remain splendid sources of insight and learning. The ideas expressed here represent a personal viewpoint and different interpretations are equally possible. Accordingly, this book should be considered as a ‘step along the way’ rather than a conclusion to the studies of the texts.
The offering contains a select bibliography and an extensive English-Italian glossary covering the fields of drama, management and leadership, and professional and personal development
