Carbon stock increases up to old growth forest along a secondary succession in Mediterranean island ecosystems.
2019
The occurrence of old-growth forests is quite limited in Mediterranean islands, which have been subject to particularly pronounced human impacts. Little is known about the carbon stocks of such peculiar ecosystems compared with different stages of secondary succession. We investigated the carbon variation in aboveground woody biomass, in litter and soil, and the nitrogen variation in litter and soil, in a 100 years long secondary succession in Mediterranean ecosystems. A vineyard, three stages of plant succession (high maquis, maquis-forest, and forest-maquis), and an old growth forest were compared. Soil samples at two soil depths (0-15 and 15-30 cm), and two litter types, relatively undec…
Impact of woody encroachment on soil organic carbon and nitrogen in abandoned agricultural lands along a rainfall gradient in Italy
2011
Land use changes represent one of the most important components of global environmental change andhave a strong influence on carbon cycling. As a consequence of changes in economy during the last century, areas of marginal agriculture have been abandoned leading to secondary successions. The encroachment of woody plants into grasslands, pastures and croplands is generally thought to increase the carbon stored in these ecosystems even though there are evidences for a decrease in soil carbon stocks after land use change. In this paper, we investigate the effects of woody plant invasion on soil carbon and nitrogen stocks along a precipitation gradient (200–2,500 mm) using original data from pa…
Reati fiscali e successione nel tempo di leggi tributarie
2013
La modifica della norma tributaria, anche di derivazione comunitaria o internazionale, che incida sugli elementi essenziali della fattispecie incriminatrice, comporta l'applicazione della disposizione più favorevole tra quella in vigore al momento della consumazione del delitto e quella successiva all'entrata in vigore.
The Relevance of Knowledge Types and Learning Pathways in Wine Family Business Succession
2013
Abstract Aspects of family business succession process are many times neglected during the life of the founder or the generation that must be getting ready for the hand-off. The paper is allowing even to a rude observer to understand the importance, the concepts, the typology and the implications of following a specific learning pathway and choosing a particular category of successor (insider or outsider), starting from situations where inside-family succession is preferable. The objective is twofold: (1) to highlight knowledge types that are easier to be transferred to internal successors, and (2) to identify context factors that facilitate family internal succession. We will demonstrate t…
Success Factors in Funding Acquisition for Research Projects through Competitive Calls: A study of R&D Public Centres
2017
Durante los últimos años, la capacidad de generación de recursos financieros derivados de la obtención de fondos competitivos ha sido una preocupación creciente para las organizaciones públicas de investigación y desarrollo (I+D), al garantizar su supervivencia y el futuro de los actuales sistemas de bienestar público implementados en la mayoría de los países europeos (Bazeley, 1998; Lee y Om, 1996; Muñoz, 2007; Santamaría, Brage-Gil, y Modrego, 2010). La literatura actual describe ampliamente las características y el impacto de los principales programas de financiación competitiva internacional (Galsworthy y McKee, 2013; Grimpe, 2012; Laudel, 2005, 2006), la magnitud de la eficacia de los …
El testament del marqués de Villatorcas i la disputa del compte de Cervelló per l'herència paterna : una altra conseqüència de l'exili austracista.
2007
Felipo Orts, Amparo - Amparo.Felipo@uv.es En el context de les conseqüències de l'exili austriacista vinculat a la Guerra de Successió, aquest article estudia els desencontres familiars que va haver de salvar don Juan Basilio de Castellví, exiliat a Viena, per a veure reconeguts els seus drets a la part de l'herència familiar que assegurava correspondreli, derivats, al seu torn, del conflicte personal que per a son pare, el marqués de Villatorcas, va haver de suposar la necessitat de disposar les seues últimes voluntats -en forma de poder públic- abans de la firma de la Pau de Viena de 1725.
Les déterminants de la réussite à l’université. Quels apports de la recherche en Éducation ? Quelles perspectives de recherche ?
2016
In France, the university is experiencing the problem of failure, especially in the first cycle. This article aims to establish, in a chronological perspective, a literature review of the contributions of educational research in the French context, the various factors contributing to this failure. The aim is firstly to show how evolved the research on the determinants of academic success since the 1990s. It is, secondly, to examine what types of research can still be conducted on the subject. That will lead us in particular that, despite questioning from several decades of university teaching, few studies have so far been conducted in the French context regarding the impact of teaching prac…
Quantitative importance of staminodes for female reproductive success inParnassia palustrisunder contrasting environmental conditions
2003
The five sterile stamens, or staminodes, in Parnassia palustris act both as false and as true nectaries. They attract pollinators with their conspicuous, but non-rewarding tips, and also produce nectar at the base. We removed staminodes experimentally and compared pollinator visitation rate and duration and seed set in flowers with and without staminodes in two different populations. We also examined the relative importance of the staminode size to other plant traits. Finally, we bagged, emasculated, and supplementary cross-pollinated flowers to determine the pollination strategy and whether reproduction was limited by pollen availability. Flowers in both populations were highly dependent o…
Introduction : From Fundamentals to Advances in Crowdfunding Research and Practice
2020
AbstractThe chapter introduces the phenomenon of crowdfunding while presenting its definition and main manifestations in recent years. It then discusses the roles played by the various parties to a crowdfunding transaction, as well as the benefits each may gain from such engagement. Overall, it argues for a win-win situation, where all parties become better off from involvement in a responsible crowdfunding engagement. Furthermore, the chapter highlights the process dimension of crowdfunding, as represented through a series of three main stages, which are further specified into a seven sub-stage model. Each stage in the process depends on successful completion of the stage preceding it and …
Latvijas jaunuzņēmumu panākumu faktori veidojot augstas izaugsmes tehnoloģiju jaunuzņēmumu
