La Cotidianidad de lo Familiar y las Habilidades de los Ni?os

Abstract: routines and rituals are a means to organize daily life. family identity, those beliefs, values, norms, rules and expectations shared among members, are also sustained by family rituals. the creation and maintenance of routine and ritual is a central element of family life and constitutes a scaffolding that supports the development of the child. daily life it may be considered a protective factor that promotes family wellbeing, increasing the sense of security, belonging, stability, cohesion and satisfaction, and strengthening social skills in children. this study aimed to analyze the relationship between family routines and rituals, and childrens' social skills. 107 families participated in this study and were administered the "family ritual questionnaire, family routines inventory, self-perception of the parental role". the study also involves teachers in the assessment of child competence through the "strengths and difficulties questionnaire". results show that not only the absence, but also the excess of routines and the emphasis on routines could lead to dysfunction in childrens' emotion regulation.
On the structure of the solution set of evolution inclusions with Fréchet subdifferentials

International Journal of Stochastic Analysis , 2000, DOI: 10.1155/s104895330000006x
Abstract: In this paper we consider a Cauchy problem in which is present an evolution inclusion driven by the Fréchet subdifferential o ∂−f of a function f:Ω→R∪{
An outline of polar spaces: basics and advances
Ilaria Cardinali
Mathematics , 2013,
Abstract: This paper is an extended version of a series of lectures on polar spaces given during the workshop and conference 'Groups and Geometries', held at the Indian Statistical Institute in Bangalore in December 2012. The aim of this paper is to give an overview of the theory of polar spaces focusing on some research topics related to polar spaces. We survey the fundamental results about polar spaces starting from classical polar spaces. Then we introduce and report on the state of the art on the following research topics: polar spaces of infinite rank, embedding polar spaces in groups and projective embeddings of dual polar spaces.
O ódio atrás das grades: da constru??o social da discrimina??o por orienta??o sexual à criminaliza??o da homofobia
Freire, Lucas;Cardinali, Daniel;
Sexualidad, Salud y Sociedad (Rio de Janeiro) , 2012, DOI: 10.1590/S1984-64872012000600003
Abstract: this article analyzes how the criminalization of homophobia became the main agenda in a national struggle for lgbt rights. the historical and cultural meaning of same-sex relations in brazil, from categories such as sodomite, uranist and homosexual to the emergence of a homosexual identity, led to the organization of a social movement with an agenda of its own. homophobia is understood as a form of discrimination. this article is a constitutional theory contribution to the analysis of the arguments in favor of criminal protection, addressing its necessity, effectiveness and possibilities, current bill proposals, and their critiques.

Study of lower hybrid wave propagation in ionized gas by Hamiltonian theory
Andrea Casolari,Alessandro Cardinali
Physics , 2013, DOI: 10.1063/1.4864582
Abstract: In order to find an approximate solution to the Vlasov-Maxwell equation system describing the lower hybrid wave propagation in magnetic confined plasmas, the use of the WKB method leads to the ray tracing equations. The Hamiltonian character of the ray tracing equations is investigated analytically and numerically in order to deduce the physical properties of the wave propagating without absorption in the confined plasma. The consequences of the Hamiltonian character of the equations on the travelling wave, in particular, on the evolution of the parallel wavenumber along the propagation path have been accounted and the chaotic diffusion of the timeaveraged parallel wave-number towards higher values has been evaluated. Numerical analysis by means of a Runge-Kutta based algorithm implemented in a ray tracing code supplies the analytical considerations. A numerical tool based on the symplectic integration of the ray trajectories has been developed.
Analysis of the Thermonuclear Instability including Low-Power ICRH Minority Heating in IGNITOR
Alessandro Cardinali,Giorgio Sonnino
Physics , 2014, DOI: 10.1140/epjd/e2015-50905-2
Abstract: The nonlinear thermal balance equation for classical plasma in a toroidal geometry is analytically and numerically investigated including ICRH power. The determination of the equilibrium temperature and the analysis of the stability of the solution are performed by solving the energy balance equation that includes the transport relations obtained by the classical kinetic theory. An estimation of the confinement time is also provided. We show that the ICRH heating in the IGNITOR experiment, among other applications, is expected to be used to trigger the thermonuclear instability. Here a scenario is considered where IGNITOR is led to operate in a slightly sub-critical regime by adding a small fraction of ${}^3He$ to the nominal $50$$\%$-$50$$\%$ Deuterium-Tritium mixture. The difference between power lost and alpha heating is compensated by additional ICRH heating, which should be able to increase the global plasma temperature via collisions between ${}^3He$ minority and the background $D-T$ ions.
Veronesean embeddings of dual polar spaces of orthogonal type
Ilaria Cardinali,Antonio Pasini
Mathematics , 2013,
Abstract: Given a point-line geometry P and a pappian projective space S,a veronesean embedding of P in S is an injective map e from the point-set of P to the set of points of S mapping the lines of P onto non-singular conics of S and such that e(P) spans S. In this paper we study veronesean embeddings of the dual polar space \Delta_n associated to a non-singular quadratic form q of Witt index n >= 2 in V = V(2n + 1; F). Three such embeddings are considered,namely the Grassmann embedding gr_n,the composition vs_n of the spin (projective) embedding of \Delta_n in PG(2n-1; F) with the quadric veronesean map of V(2n; F) and a third embedding w_n defined algebraically in the Weyl module V (2\lambda_n),where \lambda_n is the fundamental dominant weight associated to the n-th simple root of the root system of type Bn. We shall prove that w_n and vs_n are isomorphic. If char(F) is different from 2 then V (2\lambda_n) is irreducible and w_n is isomorphic to gr_n while if char(F) = 2 then gr_n is a proper quotient of w_n. In this paper we shall study some of these submodules. Finally we turn to universality,focusing on the case of n = 2. We prove that if F is a finite field of odd order q > 3 then sv_2 is relatively universal. On the contrary,if char(F) = 2 then vs_2 is not universal. We also prove that if F is a perfect field of characteristic 2 then vs_n is not universal,for any n>=2.
Embeddings of Line-grassmannians of Polar Spaces in Grassmann Varieties
Ilaria Cardinali,Antonio Pasini
Mathematics , 2013,
Abstract: An embedding of a point-line geometry \Gamma is usually defined as an injective mapping \epsilon from the point-set of \Gamma to the set of points of a projective space such that \epsilon(l) is a projective line for every line l of \Gamma, but different situations have lately been considered in the literature, where \epsilon(l) is allowed to be a subline of a projective line or a curve. In this paper we propose a more general definition of embedding which includes all the above situations and we focus on a class of embeddings, which we call Grassmman embeddings, where the points of \Gamma are firstly associated to lines of a projective geometry PG(V), next they are mapped onto points of PG(V\wedge V) via the usual projective embedding of the line-grassmannian of PG(V) in PG(V\wedge V). In the central part of our paper we study sets of points of PG(V\wedge V) corresponding to lines of PG(V) totally singular for a given pseudoquadratic form of V. Finally, we apply the results obtained in that part to the investigation of Grassmann embeddings of several generalized quadrangles.
Codes and caps from orthogonal Grassmannians
Ilaria Cardinali,Luca Giuzzi
Mathematics , 2013, DOI: 10.1016/j.ffa.2013.07.003
Abstract: In this paper we investigate linear error correcting codes and projective caps related to the Grassmann embedding $\varepsilon_k^{gr}$ of an orthogonal Grassmannian $\Delta_k$. In particular, we determine some of the parameters of the codes arising from the projective system determined by $\varepsilon_k^{gr}(\Delta_k)$. We also study special sets of points of $\Delta_k$ which are met by any line of $\Delta_k$ in at most 2 points and we show that their image under the Grassmann embedding $\varepsilon_k^{gr}$ is a projective cap.
