Riemann-Type Definition of the Improper Integrals

2004

Riemann-type definitions of the Riemann improper integral and of the Lebesgue improper integral are obtained from McShane's definition of the Lebesgue integral by imposing a Kurzweil-Henstock's condition on McShane's partitions.

Il monitoraggio topografico della cattedrale di Agrigento con metodi tradizionali

2014

L’oggetto del presente lavoro è il monitoraggio della cattedrale di San Gerlando di Agrigento, duomo eretto tra i secoli XI e XII, che sorge nella parte più alta della collina di Girgenti. Lo studio è significativo poiché, nel corso dei secoli la costruzione è stata soggetta a interventi di ristrutturazione e di consolidamento, resi necessari dai danni arrecati da frane che, in più occasioni, hanno coinvolto il territorio su cui essa sorge. Dal 2010 la chiesa è chiusa al culto per copiosi eventi franosi e idrogeologici che hanno allarmato ulteriormente anche la Protezione Civile. A seguito di questi eventi è stata avviata una campagna di indagini e monitoraggi con il fine della caratterizza…

Gli strumenti urbanistici e i piani energetici

2014

Il capitolo effettua un'analisi degli strumenti urbanistici e dei piani energetici della città di Stoccolma. L'analisi è incentrata sul piano denominato " The Walkable city", approvato già nel 2010. L'integrazione delle varie strumentazione alle varie scale sembra essere la carta vincente giocata dalla città di Stoccolma (che ambisce ad essere una città libera dai combustibili fossili nel 2050). Il City Plan è anche un documento strategico chiave per mettere in luce le strategie dello sviluppo sostenibile per fare diventare Stoccolma una città competitiva nella Vision 2030.

Exchange Rates and Stock Prices in the MENA countries: What Role for Oil?

2011

This paper considers the linkage between stock prices and exchange rates in four MENA (Middle East and North Africa) emerging markets. In contrast to the existing evidence that uses a global market index to uncover such a relationship it is found that for the sample countries oil prices emerge as the dominant factor in the above relationship. The paper considers the presence of regime shifts and evidence is found of cointegration only for the period following the 1999 oil price shock. Readjustment towards equilibrium in each stock market occurs via oil price changes. Finally, a number of robustness checks are performed and persistence profiles produced. Wiley Online Library

Intellectual evolution of strategic management and its relationship with ethics and social responsibility

2006

The main purpose here is to present an overview of the historical development of strategic management, through a critical review of the most relevant theoretical proposals, and to consider its links to ethics and corporate social responsibilities. From the very beginning of strategic management thought attempts have been made to fuse ethical aspects such as values of senior management or social values or social expectations to strategic management. More recently the stakeholder view of the firm has permitted the introduction of ethical theories into strategic management, and the resources-based view of the firm has lead to the consideration of competences, including moral virtues. Here it i…

Set-valued and fuzzy stochastic differential equations driven by semimartingales

2013

Abstract In the paper we present set-valued and fuzzy stochastic integrals with respect to semimartingale integrators as well as their main properties. Then we study the existence of solutions to set-valued and fuzzy-set-valued stochastic differential equations driven by semimartingales. The stability of solutions is also established.

Set-valued stochastic integral equations driven by martingales

2012

Abstract We consider a notion of set-valued stochastic Lebesgue–Stieltjes trajectory integral and a notion of set-valued stochastic trajectory integral with respect to martingale. Then we use these integrals in a formulation of set-valued stochastic integral equations. The existence and uniqueness of the solution to such the equations is proven. As a generalization of set-valued case results we consider the fuzzy stochastic trajectory integrals and investigate the fuzzy stochastic integral equations driven by bounded variation processes and martingales.
