A cr nica por Luís Martins: dissolu o das fronteiras entre jornalismo e literatura
Carlos Magni
Conex?o : Comunica??o e Cultura , 2009,
Abstract: Este trabalho entenderá a cr nica como um gênero híbrido, ligado tanto ao mundo objetivo das notícias quanto ao mundo subjetivo do cronista. Pelo estudo de algumas cr nicas de Luís Martins, cujo temário é a própria produ o dessa escrita, recolhemos algumas estruturas discursivas que est o na gênese dessa escrita. Luís Martins foi jornalista e escritor, trabalhou em diversos jornais cariocas e paulistas entre as décadas de 30 a 80 do século XX. Assim, numa aproxima o metalinguística, será dada voz ao cronista e jornalista Luís Martins, para que sejam exploradas as fronteiras entre a produ o jornalística e a literária. Podemos também entender que esses limites, de fato, deixam de existir quando estamos diante de um produtor que se prop e a rompê-los.
Lazy or Greedy? Impact of Xenophobic Beliefs on Natives’ Attitudes towards Redistribution  [PDF]
Raul Magni Berton
Open Journal of Political Science (OJPS) , 2013, DOI: 10.4236/ojps.2013.31005

Several recent accounts have shown that anti-immigrant feeling among citizens seems to reduce the support for the welfare state. As a consequence, the rise of immigration could produce a deep change in industrialized countries’ social security systems. This paper provides evidence that support for redistribution is not decreased by generic xenophobia, but by a specific kind of xenophobic belief. It also shows that some other xenophobic beliefs tend rather to produce a demand for governmental protection programs. Based on a multivariate analysis on individual and contextual French data, findings show that the support for social protection programs is positively related to the fear of competition from immigrants and negatively with the fear that immigrants strain the welfare state. This result can be generalized to other countries where “redistributive xenophobia” is much more widespread.

The theatrical communic-action of science
Magni Francesca
JCOM : Journal of Science Communication , 2002,
Abstract: In the writer’s opinion the frequently used expression “scientific theatre” is actually an ambiguous term, since it refers to a number of widely differing experiences. For this reason, the word “theatre” is preferred in this paper when referring to those events which take place in institutionalised settings, while the term “theatrical communic-action” is deemed more appropriate when referring to those taking place in settings devoted to scientific communication, such as museums. After a brief historical analysis of the various approaches of theatre to science and some examples of plays in Italy and abroad, the writer investigates how theatre can produce effective scientific communication in museums. Theatrical action can bring out the value of the exhibits of a museum, while creating a new way of experiencing the exhibitions. Theatrical actions link education and entertainment, consequently becoming a highly effective didactic instrument. The advantages of theatre are briefly outlined, considering it as an interpretative technique to communicate science from the point of view of the goals pursued by museums, of epistemology and of theatrical research. Hopefully, theatrical communic -action of science will become common practice in Italy, just like in Europe and the United States, where it has established itself for decades. In Italy this technique has been very seldom applied, thus hindering a thorough analysis of it. On the basis of various experiences abroad, however, the conclusion is drawn that there is probably no all-encompassing magical solution, and that the effectiveness of all different techniques of theatrical communic-action should be tested case by case.
Hysteresis properties at zero temperature in the Dipolar-Random Field Ising Model
Alessandro Magni
Physics , 1999, DOI: 10.1103/PhysRevB.59.985
Abstract: We present a modified two-dimensional random field Ising model, where a dipolar interaction term is added to the classic random field Hamiltonian. In a similar model it was already verified that the system state can exhibit domains in the form of stripe patterns, typical of thin materials with strong perpendicular anisotropy. In this work we show that the hysteresis loops obtained at zero temperature can display a strict similarity with the loops obtained in thin magnetic materials such as garnet films. In our model the processes of domain nucleation and domain wall motion are well separated in time as the system evolves. This remarkable fact allowed us to better understand the nucleation process in this family of spin systems.
Backreaction and the Covariant Formalism of General Relativity
Stefano Magni
Physics , 2012,
Abstract: This thesis is a review of backreaction, which is a possible alternative to dark energy and modified gravity. We describe in detail the 3+1 covariant formalism and Frobenius' theorem. We present the averaging procedure developed by Buchert, the Buchert equations and the generalization of these equations to the case of general matter. We then generalize to arbitrary number of spatial dimensions. We focus on the case of 2+1 dimensions, where the relation between the topology and the geometry of a surface imposes a global constraint on backreaction.
A Convergence Result for the Gradient Flow of $\int |A|^2$ in Riemannian Manifolds
Annibale Magni
Mathematics , 2014,
Abstract: We study the gradient flow of the $L^2-$norm of the second fundamental form of smooth immersions of two-dimensional surfaces into compact Riemannian manifolds. By analogy with the results obtained for the Willmore flow in Riemannian manifolds, we prove lifespan estimates in terms of the $L^2-$concentration of the second fundamental form of the initial data and we show existence of blowup limits. Under special condition both on the initial data and on the target manifold, we prove a long time existence result for the flow and subconvergence to a critical immersion.
Accurate peak list extraction from proteomic mass spectra for identification and profiling studies
Nicola Barbarini, Paolo Magni
BMC Bioinformatics , 2010, DOI: 10.1186/1471-2105-11-518
Abstract: This paper describes an original algorithm for peak list extraction from low and high resolution mass spectra. It has been developed principally to improve the precision of peak extraction in comparison to other reference algorithms. It contains many innovative features among which a sophisticated method for managing the overlapping isotopic distributions.The performances of the basic version of the algorithm and of its optional functionalities have been evaluated in this paper on both SELDI-TOF, MALDI-TOF and ESI-FTICR ECD mass spectra. Executable files of MassSpec, a MATLAB implementation of the peak list extraction procedure for Windows and Linux systems, can be downloaded free of charge for nonprofit institutions from the following web site: http://aimed11.unipv.it/MassSpec webciteMass spectrometry (MS) has been one of the most used tools to analyze large biological molecules since the introduction of the soft ionization methods, such as electrospray ionization (ESI) and matrix-assisted laser desorption/ionization (MALDI). For this reason MS is increasingly being used in proteomics. In particular, MS is exploited in proteomics to cope with two main tasks: determination of proteomic profiles of several samples for differential studies (profiling - clinical proteomics) and the identification of proteins or characterization of post-translational modifications (PTMs) in a biological sample (identification - biological proteomics) [1].The widely used protocols for protein identification or characterization of PTMs are PMF (Peptide Mass Fingerprinting) and PFF (Peptide Fragment Fingerprinting) [2-4]. MALDI-TOF is the platform generally exploited for PMF, whereas different platforms are used for PFF (e.g., ESI-Q/TOF, MALDI-TOF/TOF or ESI-FTICR) [5-7]. Electron capture dissociation (ECD) combined with ESI-FTICR is the most powerful technique for characterization of intact proteins [8-10]. For all these platforms the determination of the monoisotopic masses of the detect
Sphingolipid Metabolism Inhibitors and Cell Function
E. AlbiM. Viola Magni
The Open Enzyme Inhibition Journal , 2008, DOI: 10.2174/1874940200801010072]
Abstract: It has been widely shown that ceramide, ceramide phosphate, sphingosine and sphingosine-1-phosphate are molecules involved in cell proliferation, differentiation and apoptosis. The regulation of the enzymes that control their metabolism has an important role for cellular fate. Many studies in the field have shed light on sphingolipid metabolism inhibition and on its role in cell processes such as gene expression, DNA duplication and RNA transcription. The aim of this review is to collect, in a systematic way, the recent advances in the field of sphingolipid metabolism inhibitors, with special emphasis on their effects on cell function.

Single coronary artery from the right sinus of Valsalva
Elio Venturini,Lucia Magni
Heart International , 2011, DOI: 10.4081/hi.2011.e5
Abstract: A case of a single coronary artery originating from the right coronary sinus and bifurcating into left coronary artery (LCA) and right coronary artery (RCA) in a 74-year-old woman, with a non ST elevation acute myocardial infarction (NSTEMI) is described. The diagnosis was made with coronary angiography, that ruled out stenosis, and showed normal LCA and RCA branching. The connection path of LCA, with the opposite cusp, was defined retroaortic by multislice computed tomography (CT). The variants of this coronary anomaly, together with their clinical implications and pathophysiology of AMI are discussed. Multislice CT is fundamental for clinical decision making.
