Corporate Governance and Performance: Evidence from Italian Companies  [PDF]
Fabrizio Fratini, Patrizia Tettamanzi
Open Journal of Business and Management (OJBM) , 2015, DOI: 10.4236/ojbm.2015.32020
Abstract: The purpose of this paper is to verify the presence and intensity (extent) of the relationship between corporate governance and performance in Italian listed companies by using both accounting and non-accounting performance measures. We extended previous literature in considering all the main aspects of governance (board structure and ownership structure) and all relevant peculiarities of Italian entrepreneurial system (family business, concentrated ownership, State ownership, pyramidal groups). In the first part of the paper, we used regression analysis on a sample of 182 Italian listed companies to find that firm performance was positively related to board size and audit committee’s effort and negatively related to leverage, although with a very low coefficient. No particular relationship was highlighted for ownership structure. We tested the consistency of this finding by doing a follow-up analysis between a sub-group of 134 of 2003 sample companies and the same companies in 2007 to verify the stability of the determinants of performance and their relative impact overtime. What we found was that only board size kept its positive relation with performance. Audit committee and leverage lost their relevance in 2007 sample in which the presence of a compensation committee showed a positive impact on performance. From our findings, we can conclude that, according to other studies (Belcredi & Rigamonti [1]), the relationship among ownership and corporate governance structure and firm performance is ambiguous. The ambiguity improves if considering the relationship overtime.
L’infermiere e la comunicazione: dalla cura del paziente alla tutela del proprio benessere
Marilena Tettamanzi
Rivista di Psicologia dell'Emergenza e dell'Assistenza Umanitaria , 2012,
Abstract: A nurse faces human suffering everyday . Besides the many complex proceduresand technical competences they have to master, nurses in any department haveto relate with patients and their sufferance and to communicate with patients’relatives. Communication is one of the main aspecific instruments which a nurseneeds to be able to use. A good training in communication allows to have a positiverelation with patients and their relatives and promotes nurse’s well-being.Communication arouses intense and often negative emotions in nurses. Theseemotions, without an adequate training, can interfere with nurses’ psychosocialwell-being.The study aims to explore the connection between nurses’ communication skillsand attitudes, coping strategies, burnout and quality of life. We hypothesize thatproactive coping promotes psychological well-being and reduces risk of burnout.We also, hypothesize the existence of a mediating effect played by nurses’ communicationskills and attitudes.

Une dictature démocratique : Getúlio Vargas, raconté par Jean-Gérard Fleury
Régis Tettamanzi
Amnis , 2005, DOI: 10.4000/amnis.978
Abstract: Homme d'affaires, aviateur, journaliste et écrivain, Jean-Gérard Fleury (1905-2002) a vécu presque toute sa vie au Brésil. En 1940, il publie en France une biographie, la seule à ce jour, du président Getúlio Vargas. De nature ouvertement hagiographique, ce texte propose une lecture de la trajectoire politique de Vargas qui oscille entre démocratie et autoritarisme. De fait, cette biographie nous parle autant du Brésil que de la France : elle construit une image du président brésilien, et en même temps témoigne des aspirations idéologiques d'une certaine droite fran aise dans l'entre-deux guerres. Elle a par conséquent sa place dans une étude des représentations du populisme au XXe siècle. Hombre de negocios, aviador, periodista y escritor, Jean-Gérard Fleury (1905-2002) vivió durante casi toda su vida en Brasil. En 1940, publica una corta biografía, la única hasta hoy en francés, del presidente Getúlio Vargas. De carácter francamente hagiográfico, este texto propone una lectura de la trayectoria de Vargas que oscila entre democracia y autoritarismo. De hecho, esta biografía nos habla tanto de Brasil como de Francia: construye una imagen del presidente brasile o y, al mismo tiempo, declara las aspiraciones populistas de cierta derecha francesa entre los dos guerras mundiales. Business man, aviator, journalist and writer, Jean-Gérard Fleury (1905-2002) lived almost all his life in Brazil. In 1940, he published a short biography, the only one to this day in French, of the president Getulio Vargas; openly pictorially outlined in nature, this text offers a reading of the political trajectory of Vargas, which oscillates between democracy and authoritarianism. In fact, this biography tells us as much about Brazil as about France: it constructs an image of the Brazilian president, and at the same time witnesses the popular aspirations of a certain French political right trend between the two wars.
Charge Pumping Through a Single Donor Atom
G. C. Tettamanzi,R. Wacquez,S. Rogge
Physics , 2014, DOI: 10.1088/1367-2630/16/6/063036
Abstract: Presented in this paper is a proof-of-concept for a new approach to single electron pumping based on a Single Atom Transistor (SAT). By charge pumping electrons through an isolated dopant atom in silicon, precise currents of up to 160 pA at 1 GHz are generated, even if operating at 4.2 K, with no magnetic field applied, and only when one barrier is addressed by sinusoidal voltage cycles.
Da necessidade à liberdade: uma nota sobre as propostas de Diderot e Condorcet para o ensino superior
Piozzi, Patrizia;
Educa??o & Sociedade , 2004, DOI: 10.1590/S0101-73302004000300002
Abstract: along the xviiith century prompted by their quest for a fairer, freer and more egalitarian society, the men of the enlightenment got involved in spreading scientific and cultivated knowledge among the masses. they thought these, once enlightened about their own capacities and interests, could autonomously partake in the economical, political and social life of their nations. focusing on the relationships between the highest and lowest degrees of education, this paper explores the proposals diderot, then director of the encyclopedia, and condorcet, then a member of the legislative assembly of the revolutionary france, respectively elaborated for a universal, free public education. the renewal of the traditional contents to privilege the studies of "arts and sciences", which may be applied to practical life, and the implementation of didactics that, albeit simplifying its language, would preserve the rigor the theoretical knowledge both reveal the range and limits of this universal access formally guaranteed to common men. scrutinizing the educational ideas that stake out the course of public education shows a gap between the liberal conceptualization of promotion through merit and the democratizing vocation, which aims at a social coexistence built upon the free intertwining of people's talents, knowledge and tastes.
Utopias revolucionárias e educa??o pública: rumos para uma nova "cidade ética"
Piozzi, Patrizia;
Educa??o & Sociedade , 2007, DOI: 10.1590/S0101-73302007000300005
Abstract: during the french revolution, the confrontation of educational reform projects was a continuation of the debate inaugurated by the encyclopedists, by translating the different points of view in public policies. on the one hand, the more progressive wing of the liberal trends proposed universal access to education to offer equal opportunities and autonomy to the individuals-citizens. inspired by jean-jacques rousseau's critics to the competitive society, other trends saw educational policies as the main instrument to fight against a culture impregnated with individualism, by privileging moral and collective training. this paper explores aspects of the debate that began in revolutionary france and its echoes among the xixth century reformers of public education. it points out some of the current challenges for public education in what regards building an actually universal access and an autonomous knowledge that can be critical of the market determinations and to the competitive culture.
El léxico del Lazarillo
Olivar , 2008,
Abstract: the following is an exhaustive glossary of all the words in lazarillo registered as they appear in the text. it has been prepared in a different way from the concordances and it will soon be on line. the glossary is a useful tool to study statistical data (figures and percentages), grammar categories, most frequently used terms, dominant semantic fields, stylistic features, syntagms, term distribution, and unique terms of a given treatise, etc. the conclusion is that the novel is a very rich work from a lexical viewpoint (there are many words which are mentioned only once and there is a low rate of repeated terms). this type of survey is fundamental for studies on language and style, and for the production of a critical edition, as it provides the author's usus scribendi which can be used to assess doubtful or equal variants.
Vargas e Prestes: uma compara??o entre o trabalhismo e o comunismo no Brasil
Piozzi, Patrizia;
Trans/Form/A??o , 1983, DOI: 10.1590/S0101-31731983000100004
Abstract: this article constitutes a part of the second chapter of our m.a. dissertation - the free act: considerations on the workers' politics - faculdade de filosofia, letras e ciências humanas, universidade de s?o paulo (faculty of philosophy, letters and human sciences, university of s?o paulo). in this article, i try to show the impressive similarity between theoretical suppositions underlying a discourse that articulates a "bourgeois conception" of social relations, built for the control of the workers' class, and its supposed opponent, which intended to articulate a socialist conception and, explicity, was developing the marxist point of view. in order to attain this aim, i compare the speaches of getulio vargas (pronounced in the years of 1946 and 1947) with the discourses of luiz carlos prestes (written in 1945). i conclude this exposition with a brief reflexion over the origin of these presuppositions in the womb of the international communist moviment.
