Distributed intelligent control of exceptions in reconfigurable manufacturing systems
2003
In order to react to the continuous and unpredictable changes in product demand, in product variety, and in process technologies, reconfigurable manufacturing systems allow quick adjustment of production capacity and functionality by rearranging or changing their modular components. In this kind of system, operation management issues, such as exception handling policies, become more complex since correct reconfiguration strategies have to be selected. This paper explores the potential of the reconfigurability feature to be a basis for the development of new strategies to handle out-of-the-ordinary events in the production process; in particular, maintaining production flow when machine brea…
Reconfigurable control of robotized manufacturing cells
2007
This paper investigates the field of manufacturing system control. The addressed subject is indeed very fascinating, due to the importance that it has reached in the last decades both at research and industrial level. On the other hand, it seems to the author that most of the complexity intrinsic to the subject itself relies on the different meanings or levels of abstraction that both the terms ''manufacturing system'' and ''control'' may symbolize. The presented research aims to face the topic in a concrete fashion, i.e., by developing a control software system for a specific, although easy to be generalized, robotized manufacturing cell. Two different development methodologies, from the c…
Women as Key Agents in Sustainable Entrepreneurship: A Gender Multigroup Analysis of the SEO-Performance Relationship
2020
Literature points out that the effect of sustainable entrepreneurship on firm performance may be contingent on internal factors, such as top manager characteristics. This paper proposes that the gender of a firm&rsquo
CEO gender and SMEs innovativeness: evidence for Spanish businesses
2021
AbstractThis paper analyses the role of gender of the chief executive officer (CEO) on the propensity to introduce innovations using a sample of 1405 Spanish small- and medium-sized enterprises (SMEs). We examine whether there are significant differences between female- and male-led businesses in terms of their propensity to innovate, and whether these differences may be explained by factors related to the attributes of the CEO concerning risk tolerance, self-confidence, education level and cooperative behaviour. In particular, this study tests if the linkages between these managerial attributes and the propensity to innovate are influenced by the gender of the CEO. Using a multivariate pro…

The long memory of efficient market
2004
For the London Stock Exchange we demonstrate that the signs of orders obey a long-memory process. The autocorrelation function decays roughly as a power law with an exponent of 0.6, corresponding to a Hurst exponent H = 0.7. This implies that the signs of future orders are quite predictable from the signs of past orders; all else being equal, this would suggest a very strong market inefficiency. We demonstrate, however, that fluctuations in order signs are compensated for by anti-correlated fluctuations in transaction size and liquidity, which are also long-memory processes that act to make the returns whiter. We show that some institutions display long-range memory and others don't.
L'ottemperanza al giudicato europeo: un puzzle da costruire
2023
The paper analyses different remedies used by the Supreme Court to execute judgments of the ECHR in the Italian system. Indeed, the solution adopted by the Constitutional Court - based on the revision - was not satisfactory. Lastly, the Cartabia reform has inserted in the criminal procedure code a new remedy under the competence of the Supreme Court that will pose some practical issues.
The cerebral localization of executive functions
2018
Executive Functions (EFs) are a complex neuropsychological tool that can lead all action of daily-life indipendently from age. The attempt to associate specific regions of the central nervous system (CNS) with specific sensory functions, motor and cognitive skills is one of the most recurring themes in the history of neuroscience. The concept of cerebral localization of mental activities started from the formulations of beginning phrenologists in Nineteenth century, passing through the holistic conceptions and antilocalization that marked some periods of the Twentieth century, until the beginning of the new millennium, characterized by the enormous popularity of the techniques of functional…
Determinants of Chairman Compensation
2011
This study examines determinants of chairman compensation in a supervisory board setting and, specifically, the relationship between chairman and CEO compensation. Using a sample of publicly listed firms in Sweden, the study indicates that chairman compensation – despite its fixed nature – is reflective of firm performance via a positive relationship to CEO compensation. As CEO compensation is set before chairman compensation, we argue that the chairman may be inclined to conspire with the CEO in earnings management efforts at the expense of monitoring on behalf of investors. Supporting our argument, we find evidence that the gap between chairman and CEO compensation is less at firms where …
