Preliminary Results of a Survey of Farm Animal Biodiversity Conservation Actions in Europe Under the Framework of Agenda 2000

In this paper we report on preliminary results of a research aimed to examine the content of farm animal biodiversity conservation actions currently under implementation in the European Union in the framework of EU Agenda 2000. In particular, we surveyed sixty-three Rural Development Plans (RDPs) set up in twelve countries in application of EEC regulations 1257/99 and 1750/99. Our analysis focused on endangered breeds of six major livestock species included in the RDPs. This analysis, which is based on the comparison with the indicator's status of the DAD-IS FAO database, allowed to identify priorities in conservation efforts in each country, and estimate the level of expected public expenditure needed to ensure the moving of breeds from at-risk (of extinction) status to not-at-risk status over the period 2000-2006.farm animal biodiversity, Agenda 2000, Rural Development Plans., Livestock Production/Industries, Q18, Q20,

Loving Cultural Heritage Private Individual Giving and Prosocial Behavior

The aim of this paper is to analyse patterns of private individual giving to Cultural Heritage institutions in Italy. Based on the emerging economic literature on pro-social behavior, we carried out a Contingent Valuation survey to assess individuals’ willingness to donate to museums and heritage organizations according to different conditions and set of incentives. Our findings reveal that intrinsic motivations and accountability of the recipient institutions may be more effective drivers for eliciting charitable giving than the usually proposed fiscal incentives. The results provide avenues for future empirical research and policy suggestions for fund raising cultural institutions.Charitable Giving, Cultural Heritage, Contingent Valuation, Pro-social Behavior

One and One-Half Bound Dichotomous Choice Contingent Valuation

To reduce the potential for response bias on the follow-up bid in multiple-bound discrete choice CVM questions while maintaining much of the efficiency gains of the multiple-bound approach, we introduce the one-and-one-half-bound (OOHB) approach. Despite the fact that the OOHB model uses less information than the double-bound (DB) approach, efficiency gains in moving from single-bound to OOHB capture a large portion of the gain associated with moving from single-bound to DB. In an analysis of survey data, our OOHB estimates demonstrated higher consistency with respect to the follow-up data than the DB estimates and were more efficient as well.contingent valuation, double-bound, one-and-one-half bound

Regulation of cAMP Intracellular Levels in Human Platelets Stimulated by 2-Arachidonoylglycerol

We demonstrated that in human platelets the endocannabinoid 2-arachidonoylglycerol (2-AG) decreased dose- and time-dependently cAMP intracellular levels. No effect on cAMP decrease induced by 2-AG was observed in the presence of the adenylate cyclase inhibitor SQ22536 as well in platelets pretreated with the thromboxane A2 receptor antagonist, SQ29548 or with aspirin, inhibitor of arachidonic acid metabolism through the cyclooxygenase pathway. An almost complete recovering of cAMP level was measured in platelets pretreated with the specific inhibitor of phosphodiesterase (PDE) 3A, milrinone. In platelets pretreated with LY294002 or MK2206, inhibitors of PI3K/AKT pathway, and with U73122, inhibitor of phospholipase C pathway, only a partial prevention was shown. cAMP intracellular level depends on synthesis by adenylate cyclase and hydrolysis by PDEs. In 2-AG-stimulated platelets adenylate cyclase activity seems to be unchanged. In contrast PDEs appear to be involved. In particular PDE3A was specifically activated, as milrinone reversed cAMP reduction by 2-AG. 2-AG enhanced PDE3A activity through its phosphorylation. The PI3K/AKT pathway and PKC participate to this PDE3A phosphorylation/activation mechanism as it was greatly inhibited by platelet pretreatment with LY294002, MK2206, U73122, or the PKC specific inhibitor GF109203X. Taken together these data suggest that 2-AG potentiates its power of platelet agonist reducing cAMP intracellular level

On optimal decay estimates for ODEs and PDEs with modal decomposition

We consider the Goldstein-Taylor model, which is a 2-velocity BGK model, and construct the "optimal" Lyapunov functional to quantify the convergence to the unique normalized steady state. The Lyapunov functional is optimal in the sense that it yields decay estimates in $L^2$-norm with the sharp exponential decay rate and minimal multiplicative constant. The modal decomposition of the Goldstein-Taylor model leads to the study of a family of 2-dimensional ODE systems. Therefore we discuss the characterization of "optimal" Lyapunov functionals for linear ODE systems with positive stable diagonalizable matrices. We give a complete answer for optimal decay rates of 2-dimensional ODE systems, and a partial answer for higher dimensional ODE systems.Comment: 4 figure
