Port–City Relationship and the Environment: Literature Survey and Methodological Approach for Project Appraisal in Presence of Environmental External…
2015
AbstractIn times of increasing environmental awareness, the port–city relationship has gained new meaning because ports have been seen as the origin of both negative and positive externalities affecting public welfare. While the former are the result of port expansion, the latter are the result of transforming obsolete port areas into recreational facilities. Therefore, to support effective policymaking, this paper considers the following question: What is the scope of economic valuation of these externalities in the context of port-project appraisal? Considering their nonmarket nature, which makes economic valuation more difficult, a contingent valuation method is introduced as an economic…
The nonmarket benefits of redeveloping dockland areas for recreational purposes: the case of Castellón, Spain
2003
As a consequence of the decline of central harbour sites and the relocation of port activities to the outskirts of cities, today waterfront redevelopment has become a key issue in the urban revitalisation policies of port cities. Although we are aware that city-port regeneration has strong links with the real estate market, our purpose here is very different. In particular, the contingent valuation method (CVM) has been applied in order to obtain the nonmarket benefits of the environmental and urban improvements derived from redeveloping some port-related areas for recreational and leisure purposes in the city of Castelloèn, Spain. To date, no previous study has attempted to apply this meth…

Limit on the production of a light vector gauge boson in $\phi $ mesondecays with the KLOE detector
2012
We present a new limit on the production of a light dark-force mediator with the KLOE detector at DAPHNE. This boson, called U, has been searched for in the decay phi --> eta U, U --> e+ e-, analyzing the decay eta --> pi0 pi0 pi0 in a data sample of 1.7 fb-1. No structures are observed in the e+e- invariant mass distribution over the background. This search is combined with a previous result obtained from the decay eta --> pi+ pi- pi0, increasing the sensitivity. We set an upper limit at 90% C.L. on the ratio between the U boson coupling constant and the fine structure constant of alpha'/alpha < 1.7x10^-5 for 30<M_U<400 MeV and alpha'/alpha < 8x10^-6 for the sub-region 50<M_U<210 MeV. This…
Intra- and intermolecular forces dependent main chain conformations of esters of α,β-dehydroamino acids
2013
Abstract Esters of dehydroamino acids occur in nature. To investigate their conformational properties, the low-temperature structures of Ac-ΔAla-OMe, Ac-ΔVal-OMe, Z-(Z)-ΔAbu-OMe, and Z-(Z)-ΔAbu-NHMe were studied by single-crystal X-ray diffraction. The ΔAla ester prefers the fully extended conformation C5. Both the ΔVal and (Z)-ΔAbu esters assume the conformation β, whereas the amide analogue of the latter prefers the conformation α. For the conformations found, DFT calculations using B3LYP/6-311++G(d,p) with the SCRF-PCM and M062X/6-311++G(d,p) with the SCRF-SMD method were applied to mimicking chloroform and water environment. The tendency of the ΔVal and (Z)-ΔAbu esters towards the confo…
On the Electrostatic Component of the Adhesional Interaction between Solid Substrates and Langmuir Monolayers
1991
The work of adhesion between Langmuir monolayers and solid surfaces in a hydrophilic Langmuir-Blodgett configuration has been measured as function of the surface charge densities σ of the contacting surfaces. It was derived from the equilibrium meniscus height which was measured with the transfer fluorescence microscope. The surface charge density of the contacting surfaces was varied by changing the subphase pH. With both surfaces negatively charged (dimyristoylphosphatidylethanolamine onto SiO2-substrates) and low charge densities (σ < 1 e−/100 A2)) we observe a decrease of the adhesion with increasing charge density. At high charge densities (dimyristoylphosphatidic acid onto SiO2-substr…
The institutional pillars of management accounting function
2009
PurposeThe purpose of this paper is to theorize the institutional pillars of management accounting function.Design/methodology/approachThe paper adopts a comparative case study approach.FindingsInstitutional pillars of management accounting are explored on the basis of two longitudinal case studies. Competitive/economic forces and three analytical elements of institutional theory are composing institutions: regulative, normative and cultural‐cognitive pillars. Each element is important, and all of them may work in combination, but they operate through distinctive mechanisms and processes. This paper illustrates how they provide the basis for compliance, order and the legitimacy of not the w…
Does strategy matter? A comparison of broadband rollout policies in Finland and Sweden
2008
This study investigates broadband policies applied in Finland and Sweden with special reference to the geographical coverage of the required network infrastructure. These two Nordic countries are seen as forerunners in the development of the information society, and they also share several other similarities bearing relevance to the take-up of broadband. However, they have applied different broadband strategies: Sweden, one of the first-movers in this field, already launched its ambitious and interventionist national ICT infrastructure program in 2000, whereas the Finnish broadband strategy, published in 2003, largely relies on market forces. The present article analyses these broadband str…
Market empowerment of the patient: the French experience.
2011
Through analysis of the French experience, this article explores the way economic policy has sought to encourage active, well-informed patients by giving them market power. The new status of the patient as consumer is based on two foundations: the endeavour to build a healthcare market and the activation of demand-based policies. The keystone of this new system is a conception of the market as a process constructed by economic policy. Recent measures such as the standardization of care and the introduction of incentives to respect a treatment pathway then constitute effective levers to establish a free-market rationale.
Fluctuations of the Casimir-Polder force between an atom and a conducting wall
2007
We consider the quantum fluctuations of the Casimir-Polder force between a neutral atom and a perfectly conducting wall in the ground state of the system. In order to obtain the atom-wall force fluctuation we first define an operator directly associated to the force experienced by the atom considered as a polarizable body in an electromagnetic field, and we use a time-averaged force operator in order to avoid ultraviolet divergences appearing in the fluctuation of the force. This time-averaged force operator takes into account that any measurement involves a finite time. We also calculate the Casimir-Polder force fluctuation for an atom between two conducting walls. Experimental observabili…
