An adjusted payoff-based procedure for normal form games
Mario Bravo
Computer Science , 2011,
Abstract: We study a simple adaptive model in the framework of an $N$-player normal form game. The model consists of a repeated game where the players only know their own strategy space and their own payoff scored at each stage. The information about the other agents (actions and payoffs) is unknown. In particular, we consider a variation of the procedure studied by Cominetti et al. (2010) where, in our case, each player is allowed to use the number of times she has played each action to update her strategy. The resultant stochastic process is analyzed via the so-called ODE method from stochastic approximation theory. We are interested in the convergence of the process to rest points of a related continuous dynamics. Results concerning almost sure convergence and convergence with positive probability are obtained and applied to a traffic game. Also, we provide some examples where convergence occurs with probability zero. Finally, we verify that part of the analysis holds when players are facing a random environment.
Sociologia e Ecologia: Um Diálogo Reconstruído
Giuliani, Gian Mario;
Dados , 1998, DOI: 10.1590/S0011-52581998000100005
Abstract: sociology and ecology are often turned to in the current search for answers to two dilemmas: the crisis of paradigms within the human sciences (a product of processes of rapid yet profound changes in our present industrial society) and crises between social organizations and their surrounding physical-natural environment. the expectation that these fields will provide the answer may feed the notion that greater integration between disciplines will suffice to generate efficacious solutions to the problems underpinning these crises. on the one hand, it may seem a simple task to achieve the integration of two sciences displaying such surprising affinities. on the other, this integration can not be attained instantaneously but requires an open dialogue, where both fields are forced to make commitments and compromises and to exchange experiences.
As áreas naturais protegidas e a responsabilidade social e ambiental das empresas: o caso do Mosaico da Mata Atlantica Central Fluminense e do Comperj
Gian Mario Giuliani
Desenvolvimento e Meio Ambiente , 2007,
Abstract: The article thinks about the pressures that defy the “protected areas” in order to sustain their politics of conservation in the case that the territory had been chose for setting an enormous industrial complex. We refer to the construction of the Complexo Petroquímico do Rio de Janeiro (Comperj) by the Petrobras Company at a very short distance from the Mosaico da Mata Atlantica Central Fluminense - MMACF (a whole of 22 protected areas) and, particularly, from the Apa de Guapimirím,that is the last original haven of the mangrove system of the Guanabara Bay. It is reasonable to preview that the protected areas will suffer strong environmental and social impacts. We wont to make evident that the social and environmental responsibility flaunted by Petrobras is not preventive, in the sense of planning the actions anticipating their consequences and conceiving its project in order to avoid risks. Its social and environmental responsibility bases on attitudes that only aim at the containment of the principal predicted problems and at the compensation for the caused damages.

Enhancing Eucalyptus Community Cloud  [PDF]
Andrea Bosin, Matteo Dessalvi, Gian Mario Mereu, Giovanni Serra
Intelligent Information Management (IIM) , 2012, DOI: 10.4236/iim.2012.43008
Abstract: In the last few years, the cloud computing model has moved from hype to reality, as witnessed by the increasing number of commercial providers offering their cloud computing solutions. At the same time, various open-source projects are developing cloud computing frameworks open to experimental instrumentation and study. In this work we analyze Eucalyptus Community Cloud, an open-source cloud-computing framework delivering the IaaS model and running under the Linux operating system. Our aim is to present some of the results of our analysis and to propose some enhancements that can make Eucalyptus Community Cloud even more attractive for building both private and community cloud infrastructures, but also with an eye toward public clouds. In addition, we present a to-do list that may hopefully help users in the task of configuring and running their own Linux (and Windows) guests with Eucalyptus.
A racionalidade, a cultura e o espírito empresarial
Cappellin, Paola;Giuliani, Gian Mario;
Sociedade e Estado , 2002, DOI: 10.1590/S0102-69922002000100008
Abstract: the essay deals with the connection among the notions rationality, interest, values, and culture. in the weberian sociology, rationality is associated to the modern capitalism and to the "entrepreneurial spirit". other authors (off, hirschman, veblen, simmel, elster) discussed how difficult is to joint the modern and the rational. their analyses lead to some questions, which are relevant to the study of firm issues. firstly, the development of the capitalism really imposed and universalized the economic rationality, but it did make this process neither homogeneous, nor independent from the culture influence. secondly, values affect the economic rationality creating norms and rules, those orient actions and initiatives in order to maintain the patrimony and have profits. it is possible to speak about "firm culture" that leads to consider the firm's cultural regulations forms. such regulations are inherited from a long industrial history and have to be understood because they produce systematic effects. the "entrepreneurial spirit", as the capitalistic rationality expression, can be enriched by larger dimensions including values and practices coming from different cultural environments, such as family, community, political and social organizations. in conclusion, firms cannot be seen on the only organizational optic, because they are part of a regional and social culture and they are linked to professional cultures and their organizations. in addition, firms are able to affect different dimensions of the social life, setting-up links and exchanges with institutions, groups, and communities.
Cover art: issues in the metric-guided and metric-less placement of random and stochastic template banks
Gian Mario Manca,Michele Vallisneri
Physics , 2009, DOI: 10.1103/PhysRevD.81.024004
Abstract: The efficient placement of signal templates in source-parameter space is a crucial requisite for exhaustive matched-filtering searches of modeled gravitational-wave sources. Unfortunately, the current placement algorithms based on regular parameter-space meshes are difficult to generalize beyond simple signal models with few parameters. Various authors have suggested that a general, flexible, yet efficient alternative can be found in randomized placement strategies such as random placement and stochastic placement, which enhances random placement by selectively rejecting templates that are too close to others. In this article we explore several theoretical and practical issues in randomized placement: the size and performance of the resulting template banks; the effects of parameter-space boundaries; the use of quasi-random (self avoiding) number sequences; most important, the implementation of these algorithms in curved signal manifolds with and without the use of a Riemannian signal metric, which may be difficult to obtain. Specifically, we show how the metric can be replaced with a discrete triangulation-based representation of local geometry. We argue that the broad class of randomized placement algorithms offers a promising answer to many search problems, but that the specific choice of a scheme and its implementation details will still need to be fine-tuned separately for each problem.
On the k-normality of some projective manifolds
Alberto Alzati,Gian Mario Besana
Mathematics , 1997,
Abstract: A long standing conjecture, known to us as the Eisenbud Goto conjecture, states that an n-dimensional variety embedded with degree $d$ in the $N$- dimensional projective space is $(d-(N-n)+1)$-regular in the sense of Castelnuovo-Mumford. In this work the conjecture is proved for all smooth varieties $X$ embedded by the complete linear system associated with a very ample line bundle $L$ such that $\Delta (X,L) \le 5$ where $\Delta (X,L) = \dim{X} + \deg{X} -h^0(L).$ As a by-product of the proof of the above result the projective normality of a class of surfaces of degree nine in $\Pin{5}$ which was left as an open question in a previous work of the second author and S. Di Rocco alg-geom/9710009 is established. The projective normality of scrolls $X =\Proj{E}$ over a curve of genus 2 embedded by the complete linear system associated with the tautological line bundle assumed to be very ample is investigated. Building on the work of Homma and Purnaprajna and Gallego alg-geom/9511013, criteria for the projective normality of three-dimensional quadric bundles over elliptic curves are given, improving some results due to D. Butler.
