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,
Optimizing payments in dominant-strategy mechanisms for multi-parameter domains
No full textIn AI research, mechanism design is typically used to allocate tasks and resources to agents holding private information about their values for possible allocations. In this context, optimizing payments within the Groves class has recently received much attention, mostly under the assumption that agent’s private information is single-dimensional. Our work tackles this problem in multi-parameter domains. Specifically, we develop a generic technique to look for a best Groves mechanism for any given mechanism design problem. Our method is based on partitioning the spaces of agent values and payment functions into regions, on each of which we are able to define a feasible linear payment function. Under certain geometric conditions on partitions of the two spaces this function is optimal. We illustrate our method by applying it to the problem of allocating heterogeneous items
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
Redistribution of VCG payments in public project problems
No full textRedistribution of VCG payments has been mostly studied in the context of resource allocation. This paper focuses on another fundamental model—the public project problem. In this scenario, the VCG mechanism collects in payments up to n-1 /n of the total value of the agents. This collected revenue represents a loss of social welfare. Given this, we study how to redistribute most of the VCG revenue back to the agents. Our first result is a bound on the best possible efficiency ratio, which we conjecture to be tight based on numerical simulations. Furthermore, the upper bound is confirmed on the case with 3 agents, for which we derive an optimal redistribution function. For more than 3 agents, we turn to heuristic solutions and propose a new approach to designing redistribution mechanisms
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

Historical English Academic Robes: A Basis for a ‘National’ System
No full textFrom time to time, various writers on the subject, Franklyn included, put out a call for a ‘national’ set of robes, which could be worn by any British graduate, whatever their degree and institution, as an alternative to the robes of their alma mater. Leaving aside any benefits it might have (one can see the attraction of it for graduates of the University of East Anglia and Kent …), the great problem would be: who would design it, and who would approve it? [The author\u27s] thesis here is that the remains of such robes in fact still exist, and that it is possible to piece together the ‘national’ system fairly easily. [Excerpt]
