Implications of EU public procurement law on water service governance: the case of Italy
EU public procurement law identifies competitive tendering as the primary instrument for the selection of operators in the water sector. However, the merits of competition for the market are highly contested in the literature and theoretical debate. This paper looks at empirical evidence from Italy and assesses the implications of competitive tendering on “good governance”, with particular reference to efficiency, transparency and accountability. We draw on the policy networks tradition to capture the interdependency of actors’ interests, actors’ resources and applicable rules. Our analytical framework allows us to identify the structural limitations of competitive tendering and the associated regulation by contract. More precisely, we observe the combined effect of resource allocation (in terms of asymmetry of knowledge and power) and the nature of the applicable rules (e.g. ex-ante regulation and long term contracts). This allows for interest-seeking behaviour during both the tendering procedure and the execution of the contract. In turn, opportunistic behaviour undermines the achievement of both governance and reform objectives. Finally, we posit that introducing stronger transparency, accountability and participatory mechanisms would align actors’ interests to intended reform objectives. We put forward the following hypothesis for further empirical testing. The strengthening of governance requires the creation of opportunities for: a) involving civil society in decision making and the monitoring of operations; b) investing in the knowledge of actors participating in decision making and monitoring; c) sanctioning behaviour unaligned with reform objectives through simple and effective rules
Mixed Public-Private Enterprises in Europe: Economic Theory and an Empirical Analysis of Italian Water Utilities. Bruges European Economic Research (BEER) Papers 4/July 2006
Mixed enterprises, which are entities jointly owned by the public and private sector, are
spreading all over Europe in local utilities. Well aware that in the vast majority of cases
the preference of local authorities towards such governance structure is determined by
practical reasons rather than by the ambition to implement new regulatory designs (an
alternative to the typical “external” regulation), our purpose is to confer some scientific
value to this phenomenon which has not been sufficiently investigated in the economic
literature. This paper aims at proposing an economic analysis of mixed enterprises,
especially of the specific configuration in which the public partner acts as controller and
the private one (or “industrial” partner) as service provider. We suggest that the public
service concession to mixed enterprises could embody, under certain conditions, a
noteworthy substitute to the traditional public provision and the concession to totally
private enterprises, as it can push regulated operators to outperform and limit the risk of
private opportunism. The starting point of the entire analysis is that ownership allows the
(public) owner to gather more information about the actual management of the firm,
according to property rights theory. Following this stream of research, we conclude that
under certain conditions mixed enterprises could significantly reduce asymmetric
information between regulators and regulated firms by implementing a sort of “internal”
regulation. With more information, in effect, the public authority (as owner/controller of
the regulated firm, but also as member of the regulatory agency) can stimulate the private
operator to be more efficient and can monitor it more effectively with respect to the
fulfilment of contractual obligations (i.e., public service obligations, quality standards,
etc.). Moreover, concerning the latter function, the board of directors of the mixed
enterprise can be the suitable place where public and private representatives
(respectively, welfare and profit maximisers) can meet to solve all disputes arising from
incomplete contracts, without recourse to third parties. Finally, taking into account that a
disproportionate public intervention in the “private” administration (or an ineffective
protection of the general interest) would imply too many drawbacks, we draw some
policy implications that make an equitable debate on the board of the firm feasible. Some
empirical evidence is taken from the Italian water sector
Eosinophilic granulomatosis with polyangiitis (EGPA) and PRES: a case-based review of literature in ANCA-associated vasculitides
Eosinophilic granulomatosis with polyangiitis (EGPA) is a small-sized vessel systemic necrotizing vasculitis and belongs to the family of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides. The involvement of central nervous system in this condition is pretty rare. Posterior reversible encephalopathy syndrome (PRES) is a clinical and radiological entity described for the first time by Hinchey et al. (N Engl J Med 334(8):494-500, 1996) and characterized by MRI findings of reversible subcortical vasogenic edema predominantly in the white matter of posterior cerebral lobes. There are few case reports describing the concurrence of PRES with ANCA-associated vasculitides. We describe a case of PRES in a patient with a diagnosis of EGPA with a concise review of the literature. The exact cause of this syndrome is unknown. It has been related to eclampsia, drug-induced hypertension, renal insufficiency and also to rheumatologic diseases. Endothelial injury, hypertension and immunosuppressive medications can compromise the regulation of cerebral blood flow. In ANCA-associated vasculitides, patients presenting with symptoms of PRES represent a challenge to treatment with immunosuppressive medications. However, since an inflammatory process might be implicated, judicious use of these agents along with tight control of blood pressure and a supportive therapy may contribute to the resolution of the encephalopathic syndrome treating at the same time other manifestation related to the rheumatologic disease. Larger clinical studies are warranted to optimize the management of vasculitis-associated PRES
Static and dynamic weighing of rolling stocks by mean of a customized FBG-Sensorized-Patch
The structural health monitoring (SHM) of an infrastructure is of fundamental importance for the structure and people safety. Fiber Bragg Grating (FBG) sensors allow to design for each application, a tailored array of quasi-distributed sensors integrated to the infrastructure. To ensure the structural integrity of the railways is crucial to verify that the infrastructures comply with safety requirements to carry out their task. Railways rolling stock must comply with speed limits, the maximum number of wagons, maximum weight limit distributed on each axis of the wagons and the allowed number of trains on specific routes. The identification of the vertical load acting on each wheel is fundamental for the safety of a rolling-stock moving on a railway line. This paper presents the results of a test campaign on sensitive smart patches for static and dynamic weighing of trains. The system aims to generate a gripping system based on the magnetic force of a plastoferrite patch, taking advantage of the peculiarity that the rails are made of ferritic steel. This solution has the benefit of simplifying and speeding up the installation process and enabling a fast and easy removal or change in the configuration of the sensors array on the rail
Electrical, mechanical and electromechanical properties of graphene-thermoset polymer composites produced using acetone-DMF solvents
Recently, graphene-polymer composites gained a central role in advanced stress and strain sensing. A fundamental step in the production of epoxy-composites filled with graphene nanoplatelets (GNPs) consists in the exfoliation and dispersion of expanded graphite in a proper solvent, in the mixing of the resulting GNP suspension with the polymer matrix, and in the final removal of the solvent from the composite before curing through evaporation. The effects of traces of residual solvent on polymer curing process are usually overlooked, even if it has been found that even a small amount of residual solvent can affect the mechanical properties of the final composite. In this paper, we show that residual traces of N,N′-Dimethylformamide (DMF) in vinylester epoxy composites can induce relevant variations of the electrical, mechanical and electromechanical properties of the cured GNP-composite. To this purpose, a complete analysis of the morphological and structural characteristics of the composite samples produced using different solvent mixtures (combining acetone and DMF) is performed. Moreover, electrical, mechanical and electromechanical properties of the produced composites are assessed. In particular, the effect on the piezoresistive response of the use of DMF in the solvent mixture is analyzed using an experimental strain dependent percolation law to fit the measured electromechanical data. It is shown that the composites realized using a higher amount of DMF are characterized by a higher electrical conductivity and by a strong reduction of Young’s Modulus
A case of tension-type headache in fibromyalgia
Ref.: Ms. No. TJHP-D-10-00029R1
A 57 years-old-woman was admitted to our ward for a daily tension-type headache, non responsive to usual pharmacological treatment. Five years ago she underwent a hysterectomy. Since then, she referred muscular rigor of the neck and the shoulder girdle, intense constrictive pain localized in the occipital spine. She also reported weakness of the upper and lower limbs, tingling, tremors and difficulties in walking and climbing. She referred widespread pain, unusually severe, above all at joints and muscles, without any sign of inflammation at clinical examination. The diagnosis of a connective tissue was excluded, remaining the diagnosis of tension-type headache in Fibromyalgia the most probable one. The patient has been treated with antidepressants, anxiolytics, and antiepileptic drugs with improvement of the symptoms
