Inflorescence-visiting insects of a functionally dioecious wild grapevine
2018
The wild grapevine [Vitis vinifera L. subsp. sylvestris (Gmelin) Hegi] is the Eurasian dioecious ancestral form of mostly monoecious domesticated cultivars (Vitis vinifera subsp. vinifera). There are different hypotheses about grapevine pollination, varying from insect to wind pollination to spontaneous self-pollination. The aim of this paper is to update our knowledge on the biology of the wild grapevine by studying the insects visiting their inflorescences. During the fieldworks, floral visitors were observed, captured and identified. The most frequent insects visiting both sexes of wild grapevine were beetles (55%) followed by bees (45%). The present study shows that although in vineyard…
Reforms and decentralization: friends or foes
2013
Systemic concerns about markets, capitalism and the role of the state in the economy are salient again. Relatively large-scale reforms of economic and social arrangements are seriously considered. Historical experience suggests that reforms of that kind are sometimes associated with important changes in institutional arrangements pertaining to political decentralization. To explore the relationship between economic reforms and decentralization, the paper argues that a reform has two dimensions. It is a process and it is a design. The organization of the paper is inspired by that distinction. For economists, it seems natural to reason in terms of design -- that is, to perceive reform as the …
Soil Carbon Budget Account for the Sustainability Improvement of a Mediterranean Vineyard Area
2020
Sustainable viticulture is suggested as an interesting strategy for achieving the objectives of global greenhouse gas (GHG) emission reduction in terms of mitigation and adaptation. However, knowledge and quantification of the contribution of sustainable vineyard management on climate change impact are needed. Although it is widely assessed by several authors that the agricultural stage has a great impact in the wine chain, very few studies have evaluated the greenhouse gas emission in this phase including the ability of soil to sequester carbon (C) or the off-farm C loss by erosion. This work aimed to provide a vineyard carbon budget (vCB) tool to quantify the impact of grape production on…
Towards More Efficient Incentives for Agri-environment Measures in Degraded and Eroded Vineyards
2015
Evaluating the economic damage caused by soil erosion is important. In addition to increasing the awareness of the problem among farmers and policy makers, evaluation of the economic damage caused by erosion can promote the implementation of more sustainable soil management practices. In the present study, we describe a new approach to evaluate incentives for the adoption of agri-environment measure (AEM) in degraded and eroded vineyards. To estimate this incentive, the replacement cost (RC) and the loss of income are calculated when the vineyard is managed with conventional tillage versus a cover crop (AEM). Our findings show that the incentive could range from the loss of income due to AE…
Political Yardstick Competition and Corporate Governance in the European Union
2006
http://www.dur.ac.uk/john.ashworth/EPCS/Papers_and_Authors.php; The question whether regulatory competition in the area of company law could take place in the European Union (EU) in a way similar to the form it takes in the United States (the Delaware phenomenon) is topical because of some recent judgments of the European Court of Justice (Centros) and documents and projects produced by the European Commission. That question is typically discussed, however, as if voters did not count and as if competition among governments was exclusively based on the mobility of firms across jurisdictions. But intergovernmental competition can also take the form of yardstick, or relative performance, compe…
The Arch as a Composition Element of the Patio in Xativa. XIV-XVIII Centuries
2021
The Arch as a Composition Element of the Patio in Xativa. XIV-XVIII Centuries In the Mediterranean architectural tradition, the patio/courtyard is a “vertebral” space within the configuration of the house. It gives rise to a common typology in the former territories of the Crown of Aragon and other regions bathed by the Mare Nostrum, thus demonstrating the existence of an exchange of knowledge and culture from ancient times. In the particular case of the extinct kingdom of Valencia, as a result of the Christian conquest of the 13th century, this type began to develop, evolving over the years in terms of aesthetics, but not from the point of view of function. In this process of evolution a c…
Out of sight : Profiling soil characteristics, nutrients and bacterial communities affected by organic amendments down to one meter in a long-term ma…
2019
Common soil characteristics, nutrients and microbial activity at deeper soil depths are topics seldom covered in agricultural studies. Biogeochemical cycles in deep soils are not yet fully understood. This study investigates the effect of different mineral and organic fertilisation on soil organic matter dynamics, nutrients and bacterial community composition in the first meter of the soil profiles in the long-term maize cropping system experiment Tetto Frati, near the Po River in northern Italy. The following treatments have been applied since 1992: 1) crop residue removal (CRR), 2) crop residue incorporation (CRI), 3) crop residue removal with bovine slurry fertilisation (SLU), 4) crop re…
Interannual vineyard crop variability in the Castilla–La Mancha region during the period 1991–1996 with Landsat Thematic Mapper images
2004
The vineyard crop is considered an indicator of vegetation cover processes in the Castilla–La Mancha region, as the crop has undergone far-reaching changes in the last ten years: abandonment, removal of vineyards and replacement with other crops such as cereal. The so-called ‘Change detection’ is a process that allows identification of differences in the state of the vineyard by observing it at different times. Essentially, it involves the ability to quantify temporal effects using multi-temporal datasets. The aim of this study is to analyse the vineyard variability during the period 1991–1996 using different Landsat-5 Thematic Mapper (TM) images belonging to an identified period that highl…

Decentralization as an incentive scheme when regional differences are large
2010
It has been suggested that large regional differences could be an obstacle to that part of the political accountability of office-holders which is based on yardstick competition among governments. The paper addresses that question and concludes that the obstacle is not too serious in general. The second part of the paper is devoted to the persistent economic underperformance of some regions in countries such as Germany, Italy and (with regard to regions overseas) France. How is it that the mechanism of yardstick competition induces a convergence of economic performance among European Union member countries, even those particularly poor initially, but fails to induce all the underperforming …
