ON THE LIPSCHITZ REGULARITY FOR MINIMA OF FUNCTIONALS DEPENDING ON x, u, AND ∇u UNDER THE BOUNDED SLOPE CONDITION
No full textWe prove the existence of a global Lipschitz minimizer of functionals of the form
I (u) =
\int
\Omega f(\nabla u(x)) + g(x, u(x)) dx, u \in \phi + W1,1
0 (\Omega ), assuming that \phi satisfies the bounded slope
condition (BSC). Our assumptions on the Lagrangian allow the function f to be strongly degenerate
On the Lavrentiev phenomenon and the validity of Euler-Lagrange equations for a class of integral functionals.
No full textAbstractWe study the functionalJ(x)=∫baƒ(t,x(t),x′(t))dt and provide conditions on the integrand ƒ excluding the Lavrentiev Phenomenon and ensuring the validity of Euler-Lagrange Equations
Local Lipschitz continuity for energy integrals with slow growth and lower order terms
Full text linkWe consider integral functionals with slow growth and explicit dependence on u of the Lagrangian; this includes many relevant examples as, for instance, in elastoplastic torsion problems or in image restoration problems. Our aim is to prove that the local minimizers are locally Lipschitz continuous. The proof makes use of recent results concerning the Bounded Slope Conditions
An estimate concerning the difference between minimizer and boundary value in some polyconvex problems
Full text linkThis paper is concerned with regularity of minimizers of integral functionals with polyconvex potentials. In particular we obtain bounds on the difference |u−u∗|∞ for minimizers u:Ω⊂R3→R3 of problem min∫Ωf(x,Dv(x))dx,v∈u∗+W01,p(Ω,R3)
Le novità del contratto di somministrazione di lavoro
No full textAllo scopo di disincentivare l’instaurazione di rapporti di lavoro non stabili, il cd. “decreto dignità” (d.l.12.7.2018, n. 87, conv. con mod. dall’art. 1, co. 1, l. 9.8.2018, n. 96), parallelamente alle modifiche sul contratto a tempo determinato, è intervenuto anche sulla disciplina del contratto di somministrazione di lavoro, creando tra i due istituti una forte interazione che se da un lato consente di risolvere alcune problematiche sorte all’indomani dell’emanazione del d.lgs. 15.6.2015, n. 81, dall’altro lato, però, ne crea di nuove per il non facile coordinamento tra le due fattispecie
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
