Existence Results for Periodic Boundary Value Problems with a Convenction Term

2020

By using an abstract coincidence point theorem for sequentially weakly continuous maps the existence of at least one positive solution is obtained for a periodic second order boundary value problem with a reaction term involving the derivative \(u'\) of the solution u: the so called convention term. As a consequence of the main result also the existence of at least one positive solution is obtained for a parameter-depending problem.

Ordinary (p_1,...,p_m)-Laplacian system with mixed boundary value

2016

In this paper we prove the existence of multiple weak solutions for an ordinary mixed boundary value system with (p_1,...,p_m)-Laplacian by using recent results of critical points.

Distribution, function and predictive value of tumor-infiltrating γδ T lymphocytes

2013

Although γδ T cells are known to exert both tumor-preventing and tumor-promoting activity, there is still little information on the functional characteristics and clinical significance of γδ T cells isolated from the tumor site. In a recent study, we have investigated the distribution of different γδ T-cell populations in melanoma and their impact on disease outcome.

Diagnostic, Prognostic and Therapeutic Value of Gene Signatures

2012

Gene expression studies have revealed diagnostic profiles and upregulation of specific pathways in many solid tumors. Some gene-expression signatures are already used as predictors of relapse in early breast cancer patients. The explosion of new information in gene expression profiling could potentially lead to the development of tailored treatments in many solid tumors. In addition, many studies are ongoing to validate these signatures also in predicting response to hormonal, chemotherapeutic, and targeted agents in breast cancer as well as in other tumors. This book has been carried out with the aim of providing readers a useful and comprehensive resource about the range of applications o…

Techniques to evaluate erythrocyte deformability in diabetes mellitus

2005

Using several rheological techniques, we examined the erythrocyte deformability in different groups of diabetic subjects. The macrorheological techniques used for this evaluation were respectively whole-blood filtration, filtration of erythrocyte suspensions, polyviscosimetry and diffractometry. Whole-blood filterability, at a negative pressure of 20 cm water, was decreased in type 2 diabetics; no difference was evident at a negative pressure of 10 cm water. The filtration of erythrocyte suspensions at low haematocrit (5%) did not show differences between normal and diabetic subjects. The polyviscosimetry, which explores the filterability of erythrocyte suspensions at high haematocrit (80%)…

Understanding the Microfoundations of Entrepreneurial Ecosystems: Toward a Value-Based Method and Theory

2023

Despite the progress made by scholars, empirically investigating entrepreneurial ecosystems (EEs) remains problematic because of the inherent complexities and nonlinearities of interactions among EE actors. The research to date has shown a tendency to focus on macrolevel ecosystem dynamics while neglecting the microfoundations of EEs. We contend that this negligence is due to a lack of appropriate methodologies that can capture EE microfoundations through a systemic value-based perspective. To fill this gap, in this article, we propose a novel methodological approach, the value system method, which enables framing EEs through critical causal interdependences between key actors’ business mod…

From Cash to Accrual Accounting: The seminal case of the Sicilian Regional Public Bodies

2019

The Italian public sector has been traditionally characterised by a cash-based and compliance-oriented governmental accounting, principally aimed at supporting the budgetary control by the legislative body. Over the last few decades, however, a new movement has been spreading around the world, casting doubt on the potentialities and advantages of the traditional accounting system in favour of an accrual basis one. This paper traces the progressive introduction of a complete accrual accounting by the Sicilian Regional public bodies – within the context of international and national public management changes – pursuing the ultimate goal to improve efficiency, accountability and transparency. …

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…
