Organizzazioni corrotte: quando la corruzione diventa sistema
2020
There is abundant empirical evidence which shows that corporate corruption is not so much the result of episodic events or favorable occasions, exploited by inveterate criminal minds or people of doubtful morality, but the result of widespread behavior that reflects substantial institutional weaknesses. This article, therefore, aims to clarify the individual, social and institutional processes that generate systemic corruption within public and private organizations. To this end, some reflections on the concept of corruption are also made. The reasons why organizations have a certain propensity for corruption are explained below. In the central part of the text, the organizational processes…
Whistle-blowing and Education Management
2016
Contemporary management studies usually concern positive and desir- able solutions that increase the organizational effectiveness and perfor- mance. That is why graduates of higher business schools, equipped with idealistic views on business environment, need to face the dark side of business practice without the appropriate preparation. Their unawareness of the risk associated with management misconduct results in corrupt scandals, erosion of public trust to their organizations, or even the collapse of profitable corporations. Underestimation of unethical behaviors may lead to severe consequences. The last decade, in fact, has been abundant in numerous examples of corruption scandals in mo…

A study of the human rod and cone electroretinogram a-wave component
2009
The study of the electrical response of the retina to a luminous stimulus is one of the main fields of research in ocular electrophysiology. The features of the first component (a-wave) of the retinal response reflect the functional integrity of the two populations of photoreceptors: rods and cones. We fit the a-wave for pathological subjects with functions that account for possible mechanisms governing the kinetics of the photoreceptors. The paper extends a previous analysis, carried out for normal subjects, in which both populations are active, to patients affected by two particular diseases that reduce the working populations to only one. The pathologies investigated are Achromatopsia, a…
Analysis of the thermomechanical behavior of the IFMIF bayonet target assembly under design loading scenarios
2015
In the framework of the IFMIF Engineering Validation and Engineering Design Activities (IFMIF/EVEDA) phase, ENEA is responsible for the design of the European concept of the IFMIF lithium target system which foresees the possibility to periodically replace only the most irradiated and thus critical component (i.e., the backplate) while continuing to operate the rest of the target for a longer period (the so-called bayonet backplate concept). In this work, the results of the steady state thermomechanical analysis of the IFMIF bayonet target assembly under two different design loading scenarios (a "hot" scenario and a "cold" scenario) are briefly reported highlighting the relevant indications…
A normative ‘due process’ in the creation of States through secession
2006
The choice and/or the balancing between effectivess and legality in the creation of States is, today, one of the most hotly debated issues in the international legal scholarship. Should a state-like entity formed in breach of the peremptory norm prohibiting the use of force or of the principle of self-determination (not) be considered as a State for the purposes of international law? The answer differs according to what theoretical premises are adopted. For those who believe that the State is a social person, and its creation basically a historical occurrence, the law cannot cancel its very existence. On the other hand, if State-creation is also a matter of law, one might agree that “[a]n a…
Excitability regulation in the dorsomedial prefrontal cortex during sustained instructed fear responses: a TMS-EEG study
2018
AbstractBackgroundThreat detection is essential for protecting individuals from precarious situations. Early studies suggested a network of amygdala, limbic regions and dorsomedial prefrontal cortex (dmPFC) involved in fear processing. Excitability regulation in the dmPFC might be crucial for physiological fear processing, while an abnormal excitability pattern could lead to mental illness. Non-invasive paradigms to measure excitability regulation during fear processing in humans are missing.MethodsWe adapted an experimental approach of excitability characterization using electroencephalography (EEG) recordings and transcranial magnetic stimulation (TMS) over the dmPFC during an instructed …
Trust-enhanced data integrity model
2012
In this paper we propose an enhancement of data integrity model. The proposed model is based on the idea of Biba integrity model but uses more elaborated integrity measurements. Since integrity can be seen as “trustworthiness of data and resources”, we propose to utilize trustworthiness opinions from subjective logic and express levels of integrity as levels of trustworthiness.
Secure, dependable and publicly verifiable distributed data storage in unattended wireless sensor networks
2010
Published version of an article from the journal : Science in China, Series F: Information Sciences. The original publication is available at Spingerlink. http://dx.doi.org/10.1007/s11432-010-0096-7 In unattended wireless sensor networks (UWSNs), sensed data are stored locally or at designated nodes and further accessed by authorized collectors on demand. This paradigm is motivated by certain scenarios where historical or digest data (e.g., average temperature in a day), instead of real-time data, are of interest. The data are not instantly forwarded to a central sink upon sensing, thereby saving communication energy for transmission. Such a paradigm can also improve data survivability by m…
Impact of Superfinish Turning on Surface Integrity of Pure Copper
2011
Abstract The presented study deals with comprehension of relationships between machining cutting conditions and physical-chemical properties linked with surface integrity. A multi-physics model is presented to calculate residual stress, temperature and dislocation fields in the machined material. This model includes both thermal-mechanical, structural evolution and dynamic recristallisation approaches. The model was applied to pure copper after superfinish turning. Good agreement was found between numerical values and experimental ones. This paper also presents a work on the impact of mechanical and microstructural changes induced by machining on the electrochemical behaviour and corrosion …
