'E-HCM' project: Cost calculation model for surgical procedures
No full textThe economic and financial crisis has also had an important impact on the healthcare sector. Available resources have decreased, while at the same time costs as well as demand for healthcare services are on the rise (Mladovsky et al., 2012; Oduncu, 2012). This coalescing negative impact on availability of healthcare resources is exacerbated even further by a widespread ignorance of management accounting matters. Little knowledge about costs is a strong source of costs augmentation. Although it is broadly recognized that cost accounting has a positive impact on healthcare organizations, it is not widespread adopted (Kaplan/Porter, 2011). Hospitals are essential components in providing overall healthcare (McKee/Healy, 2002). Operating rooms are critical hospital units not only in patient safety terms but also in expenditure terms (Guerriero,/Guido, 2011; Maryamaa/Kirvela 2007). Understanding OR procedures in the hospital provides important information about how health care resources are used (Elixhauser/Roxanne, 2007). There have been several scientific studies on management accounting in healthcare environments (see for example van Rensburg/Jassat 2011; Lievens/Van den Bogaert/Kesteloot 2003; Chan 1993) and more than ever there is a need for innovation, particularly by connecting business administration research findings to modern IT tools. IT adoption constitutes one of the most important innovation fields within the healthcare sector, with beneficial effects on the decision making processes (Tan, 2005). The e-HCM (e-Healthcare Cost Management) project consists of a cost calculation model which is applicable to Business Intelligence. The cost calculation approach comprises elements from both traditional cost accounting and activity-based costing. Direct costs for all surgical procedures can be calculated through a seven step implementation process. © Springer International Publishing Switzerland 2014
Refractive index measurement in TCO layers for micro optoelectronic devices
No full textThe operation of micro-optoelectronic devices relies on optical properties of materials, first of all the wavelength dependent refractive index. Standard measurement techniques are often prone to significant ambiguities caused by the periodic nature of the optical response. In this paper we propose a procedure which exploits transmittance measurements, performed at variable light incidence angle, to reconstruct the complex refractive index as a function of the wavelength. Experiments performed on a thin TCO layer prove the reliability of the method. © 2014 IEEE
Thermal Stability of Sputtered Tungsten Nitrides for Solar Thermal Applications
No full textIn this work, tungsten nitrides sputtered at different powers supplied to a W target (300 W, 500 W, 700 W) and proposed for solar thermal applications as part of solar absorbers, as active and robust materials for capacity energy storage and as plasma-facing materials were annealed in vacuum at medium-high temperatures (470 °C, 580 °C) and characterized by means of X-ray diffraction (XRD), AFM, micro-Raman, FTIR, UV–VIS–-NIR, sheet, surficial energy and wetting angle measurements. From the overall set of analyses, some important modifications and differences between samples after annealing emerged (which will be useful for selecting them for specific applications) and have been correlated to sputtered W metallic clusters’ ability to adsorb, form complexes with and react with the strong N2 triple bond under the various plasma conditions of a reactive sputtering process. In particular, the 300 W film of poor crystalline quality as deposited, after annealing released entrapped nitrogen and retained its W2N structure up to a temperature of 580 °C. Despite there being no phase transition, there was an increase in sheet resistance, which is detrimental because the preservation of metallic character is an important requisite for the proposed applications. The 500 W film had a stable crystalline structure and a metallic character unmodified by increasing temperature. The 700 W film, whose structure as deposited was almost amorphous, underwent the most severe modification after annealing: crystallizing, disproportioning and giving rise to a composite and porous nature (W + WNx) not ideal for spectrally selective coating applications, but useful for tailoring capacitive energy storage devices, or for catalysts for hydrogen evolution reactions (as an alternative to platinum) in alkaline water electrolysis
Aluminium Nitride Doping for Solar Mirrors Self-Cleaning Coatings
No full textSoiling severely reduces solar mirror performance, requiring dispendious water consumption for cleaning operations and causing an increase in the levelized cost of energy (LCOE). An emerging technology for facing this problem consists of developing transparent self-cleaning coatings, able to be washed with a small amount of water by virtue of the modulation of surficial wetting properties. Nevertheless, the beneficial effects of coatings decrease in the first year, and coated mirrors show even higher soiling than non-coated ones. Moreover, it is important that coating production processes are economically convenient, consistent with the intended reduction of overall costs. The aim of this work is the research and development of a cheap and scalable solution, compatible with mirror fabrication steps and, in such a sense, economically advantageous. It involves the substitution of the alumina last layer of solar mirrors with more hydrophobic, potentially auxetic aluminum compounds, such as nitrides. In particular, 2D inorganic aluminum nitride thin films doped with metals (such as aluminum and silver) and non-metals have been fabricated by means of reactive sputtering deposition and characterized for the purpose of studying their self-cleaning behavior, finding a trade-off between wetting properties, optical clarity, and stability
Microstructure evolution of room-temperature-sputtered ITO films suitable for silicon heterojunction solar cells
No full textThickness influence on structural, optical and electrical properties of sputtered indium tin oxide (ITO) with thickness ranging from 60 up to 430 nm films has been studied. At the increase of the film thickness crystallinity degree and grain size increased, whereas tensile structural distortion as well as resistivity decreased. It was observed that a microstructure evolution takes place: the initial amorphous layer evolved in polycrystalline phase, with a grain–subgrain surface morphology. Carrier concentration increased at the increase of the film thickness and a general relationship between electrical characteristics and structural distortion has been found. In thinner films larger tensile distortion allowed to include larger amount of interstitial O and/or Sn atoms in the lattice. An appreciable impact of the thickness was also observed on electro-optical properties in terms of changes in energy gap, resistivity and optical absorption. Silicon heterojunction solar cells have been produced and Jsc as high as 33.0 mA/cm2 has been obtained
Sicurezza e Democrazia. Bezpieczenstwo i Demokracja. Atti del X Colloquio italo-polacco sulle trasformazioni istituzionali, Bari-Foggia, 19-20 ottobre 2023
No full textL’obiettivo di questo libro è approfondire il tema dei rapporti tra sicurezza e democrazia in Italia e Polonia, nonché quello delle connessioni tra sicurezza esterna e politiche di difesa nell’Unione europea. Raccogliendo gli interventi e i contributi del X Colloquio italo-polacco sulle trasformazioni istituzionali nei due Paesi, svoltosi in Puglia (Bari-Foggia, 19-20 ottobre 2023), nel Volume ci si interroga sul cruciale tema dei rapporti tra sicurezza e democrazia, traguardandolo da diverse prospettive e soffermandosi su alcuni profili, in particolare: le nuove dimensioni della sicurezza negli Stati democratici in relazione a sovranità, diritti e Costituzioni; la sicurezza ‘esterna’ e le politiche di difesa tra gli Stati nazionali e l’Unione europea; la sicurezza in relazione alle nuove tecnologie e, infine, la sicurezza in rapporto al tema del controllo democratico sulla circolazione dei dati e la loro trasparenza. Se il nesso tra le politiche di difesa e la sicurezza esterna degli Stati nazionali appare, in particolare in questo momento storico, di particolare attualità, anche le recenti imponenti evoluzioni tecnologiche pongono una serie di importanti “sfide” alla sicurezza del cittadino e dei suoi dati, riaffermando il ruolo di garanzia del diritto costituzionale ed europeo. Dall’analisi condotta nel Volume emerge quindi la necessità di un approccio multilivello e globale alla sicurezza e tutta la multidimensionalità di un legame sempre più inscindibile tra i concetti di sicurezza e democrazia
I rapporti tra Parlamento e Corte costituzionale nella garanzia dei diritti sociali
No full textIl contributo affronta il tema dei rapporti tra Parlamento e Corte costituzionale dallo specifico punto di vista della garanzia dei diritti sociali. La riflessione si propone perciò di osservare dinamicamente come il controllo di legittimità costituzionale interagisca con l’esercizio della discrezionalità legislativa nella concreta attuazione della forma di Stato sociale.
L’indagine si sofferma sull’evoluzione che ha caratterizzato la giurisprudenza degli ultimi anni in materia di diritti sociali. Anzitutto, si evidenzia come oramai il criterio dominante utilizzato dal Giudice di costituzionalità nel sindacare le leggi attuative dei diritti sociali sia quello, dai contorni non esattamente definiti, del “ragionevole bilanciamento” che deve sussistere tra la previsione di (costose) prestazioni pubbliche e la necessità di salvaguardare l’equilibrio finanziario del sistema. Viene altresì posto in luce come, per la Corte, il bilanciamento legislativo non possa essere ritenuto ragionevole quando comprometta il “nucleo essenziale” di un diritto sociale. Inoltre, si constata come siano diminuite in modo drastico le c.d. “sentenze di spesa”; quelle, cioè, attraverso cui la Corte, trovando illegittime le restrizioni contenute nelle scelte legislative, aggiunge o estende prestazioni pubbliche a beneficio dei cittadini. Infine, si fornisce un quadro di sintesi dei rapporti che, in questi anni di crisi economica, si sono creati tra Giudice delle leggi e Parlamento in materia di diritti sociali, rilevando una sostanziale consonanza – pur con qualche eccezione – in vista del contenimento della spesa pubblica.The speech deals with the relationship existing between Parliament and Constitutional Court in the protection of social rights. It aims, therefore, at analyzing how the constitutional review of the legislation interacts with the legislative discretion in the welfare state’s actual implementation.
The analysis focuses on the evolution of last years’ jurisprudence about social rights. First, it stresses that the balancing test has became the prevalent criterion adopted by the Constitutional Court in the review of statutes dealing with the implementation of social rights: through this test, the Court is able to balance the cost of public services with the financial balance of the government. The author sheds light on the perspective of the Court: in the review of the legislation, the Court refuses to consider as “reasonable” a norm which infringes the core of a social right.
Furthermore, the speech explains the decrease of a specific kind of judgments, called “Spending Judgments”, i.e., judgments through which the Court, due to the unconstitutionality of a norm, expands public services.
As a conclusion, the speech outlines a framework of the relationships between Parliament and the Courts that have been produced during the economic crisis, pointing out a substantial consistency – even though with few derogations – in pursuing the goal of a reduction in public spending
