No full textQuali sono le motivazioni profonde che spingono un marito, un amante, un compagno, una fidanzata a trasformarsi in stalker? E perché la vittima alle prime avvisaglie di aggressività non allontana da sé la persona che la minaccia ma gli resta accanto negando l’evidenza dei fatti? Cosa si fa per incoraggiare la vittima a rompere il silenzio e a denunciare l’abuso? Partendo da questi cruciali interrogativi il testo intende contribuire all’individuazione e analisi dei fattori che principalmente motivano la violenza, focalizzando la relazione triadica molestia–vittima–paura, il quadro di personalità e gli aspetti comportamentali di ciascun membro della coppia stalker–vittima che caratterizzano il fenomeno stalking. In particolare, la disamina della normativa in previsione del delitto di “Atti persecutori” integra e definisce più precisamente i reali bisogni della vittima e l’atteggiamento ossessivo dello stalker, affrontando la fattispecie di reato prevista dall’art. 612-bis c.p., e, segnatamente, le esigenze di tutela sociale che hanno portato alla sua introduzione, la struttura del reato attraverso un’analisi dell’autore di condotte criminose e degli eventi necessari per la integrazione del delitto, la giurisprudenza in materia, le misure adottabili contro l’autore del reato e le misure a sostegno delle vittime, con evidenziazione delle relative criticità
Gaussian Poincare Inequalities on the Half-Space with Singular Weights
No full textWe prove Rellich–Kondrachov-type theorems and weighted Poincaré inequalities on the half-space R+N+1={z=(x,y):x∈RN,y>0} endowed with the weighted Gaussian measure μ:=yce-a|z|2dz where c+1>0 and a>0. We prove that for some positive constant C>0, one has (Formula presented.) where u ̄=1μ(R+N+1)∫R+N+1udμ(z). Besides this, we also consider the local case of bounded domains of R+N+1 where the measure μ is ycdz
Sharp kernel bounds for parabolic operators with first order degeneracy

Asymptotic behaviour for elliptic operators with second-order discontinuous coefficients

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
