A Lebesgue-type decomposition on one side for sesquilinear forms

2021

Sesquilinear forms which are not necessarily positive may have a dierent behavior, with respect to a positive form, on each side. For this reason a Lebesgue-type decomposition on one side is provided for generic forms satisfying a boundedness condition.

Admissible perturbations of alpha-psi-pseudocontractive operators: convergence theorems

2015

In the last decades, the study of convergence of fixed point iterative methods has received an increasing attention, due to their performance as tools for solving numerical problems. As a consequence of this fact, one can access to a wide literature on iterative schemes involving different types of operators; see [2, 4, 5]. We point out that fixed point iterative approximation methods have been largely applied in dealing with stability and convergence problems; see [1, 6]. In particular, we refer to various control and optimization questions arising in pure and applied sciences involving dynamical systems, where the problem in study can be easily arranged as a fixed point problem. Then, we …

Forensic Microbiology: A Case Series Analysis

2019

The importance of microbial colonization of human organs in a living body has long been assessed. What still remains unclear are the microbial changes occurring after death, thus leading to the advent of a relatively novel field of research called “Postmortem microbiology”. It is applied to several forensic fields such as post-mortem interval assessment and cause of death determination. In this contest, a major limit is thus represented by the correct interpretation of the microbial data and by the actual lack of standard procedures. Here we propose a standard operative protocol in order to avoid false positives given by contamination (the main problem), post-mortem translocation and agonal…

GESTIONE PERIOPERATORIA DEI BAMBINI AFFETTI DA NEUROBLASTOMA E IPERTENSIONE TUMORE-DIPENDENTE: STUDIO DEL GRUPPO ITALIANO DI CHIRURGIA ONCOLOGICA PED…

2015

Il Neuroblastoma (NB) con sintomatologia ipertensiva riveste un’esigua percentuale dei tumori neuroblastici trattati ogni anno, attualmente in letteratura esistono unicamente due studi (1,2), che riportano un’incidenza di sintomatologia ipertensiva del 10-19% dei casi. Il follow-up dei pazienti studiati risulta breve, inoltre il meccanismo fisiopatologico non è stato tuttora dimostrato, ipotizzando una combinazione tra la compressione del peduncolo vascolare renale e la secrezione di catecolamine urinarie. Per quanto riguarda il management intra-operatorio, che può risultare difficoltoso a causa di picchi iper\ipotensivi durante la manipolazione della massa, esistono unicamente case reports…

2021

Introduzione. La tubercolosi (TB) rappresenta ancora oggi un problema di salute pubblica a livello globale. Sebbene l’incidenza mostri ampie differenze geografiche, la TB rappresenta una delle più importanti cause di morte e quella principale da singolo agente infettivo (3). Si stima che un terzo della popolazione mondiale risulti infettata in forma latente da ceppi di Mycobacterium tuberculosis. L’infezione tubercolare latente (ITBL) e la TB costituiscono ancora oggi, un rischio professionale per gli operatori sanitari e soggetti a questi equiparati, quali studenti che svolgono attività formativa professionalizzante in ambito assistenziale. La maggior parte dei casi di malattia attiva di o…

Scritti in onore di Pellegrino Capaldo

2014

La qualità dei servizi è stata riconosciuta come un rilevante aspetto caratterizzante la performance dell’azienda pubblica, analogamente alla capacità di operare secondo criteri di efficienza e nel rispetto dei vincoli di bilancio. Sebbene sia possibile riscontrare alcuni significativi casi di adozione di politiche di customer satisfaction nelle amministrazioni pubbliche italiane, a tutt’oggi il tema presenta significative criticità, specialmente in ordine agli aspetti metodologici e agli strumenti operativi che consentano di integrare dette politiche nel sistema di programmazione e controllo delle aziende che erogano tali servizi. Il presente lavoro adotta una diversa prospettiva di analis…

Settore SECS-P/07 - Economia AziendaleQuality in delivering public services has been recognised as a major issue challenging performance in the public sector as well as the ability to operate effectively and within budget constraints. Empirical findings shown by the literature demonstrate that concrete efforts have been produced towards the evaluation and improvement of satisfaction levels of citizens and other Public Administration’s ‘customers’. However still today this issue portrays many unresolved criticalities particularly concerning the methodological approaches and operative tools to adopt in order to integrate ‘customer satisfaction’ programs with the wider organisational control system in each public administration. This paper adopts a non-conventional view of the ‘customer satisfaction’ concept. This is currently meant as a matter of social reporting or even statistical analysis based on the users’ perceptions on the level of provided services by a given (front office) unit in the public sector. Here an inter-institutional perspective is adopted with a view to map the overall value chain leading to the final product delivered to citizens or the community. Inside this chain tracking the underlying administrative products delivered by back-office units to their ‘internal clients’ in the public administration is recommended as a fundamental step to understand how to improve performance in satisfying citizens’ needs. This should also require a proper link between the administrative units’ goals and performance measures to the desired efficiency and effectiveness of processes leading to the attainment of administrative products providing the basis of the final services delivered to the private sector. Based on first empirical findings from field analysis in the Italian context the paper aims to outline an approach which could assist both politicians and managers to better assess and improve performance according to a customer satisfaction perspective.

Understanding short- and long-term implications of “myopic” fleet maintenance policies: a system dynamics application to a city bus company

2010

Financial losses recorded in city bus companies often force managers to implement restructuring strategies aimed at improving business results. However, such decisions may not produce the expected consequences for a number of reasons. Both the internal and external environment in which such companies operate can make the design and implementation of long-term sustainable policies quite difficult. In fact, the result may be that decision makers introduce "effective" policies in a company subsystem, while ignoring the medium- and long-term implications of such decisions in the performance of the whole company. With the aim to detect the main causes underlying "myopic" fleet maintenance polici…
