Nuova introduzione allo studio del diritto inglese. Le fonti
2016
Nella prefazione alla terza edizione, pubblicata nel 2000, alla Sua introduzione allo studio del diritto inglese l’Autore esprimeva un punto di vista risoluto e chiaro, consistente nella necessità della conoscenza del diritto inglese allo scopo di accrescere il dialogo tra i giuristi europei. E questo perché il riferimento al common law implica il rinvio a strutture di pensiero, a categorie giuridiche, a modelli normativi che comunque rappresentano esperienze originali e rilevanti nel continente europeo e possono orientare delicate scelte di politica del diritto in ambito comunitario: a tal proposito Giovanni Criscuoli ricordava come nel dibattito circa i possibili criteri di redazione dei …
Nuova introduzione al diritto inglese
2021
Il passaggio del tempo è già di per sé una ragione sufficiente per consigliare l’aggiornamento di un’opera attraverso la pubblicazione di una sua nuova edizione che contempli anche solo informazioni ed opinioni sopravvenute relative alla materia trattata. Il quinquennio trascorso da quando vide la luce la “Nuova introduzione allo studio del diritto inglese”, prosecuzione ideale e tematica dell’originaria fatica di Giovanni Criscuoli all’inizio del XXI secolo non è, tuttavia, la sola circostanza che mi ha indotto a curare e ad assumere la gravosa responsabilità della rinnovata edizione, sempre avvalendomi dell’indicazione con un asterisco delle parti da me direttamente redatte. Essa si è res…
The Role of Searle's Constitutive Rules for the Rational Criticizability of Institutional Reality
2013
My hypothesis is that we can derive the normative conditions that institutions and institutional acts have to meet in order to be rationally acceptable/recognizable from the logical structure of institutional reality. Developing Searle's achievements on the constitutive role of speech acts in the construction of institutional reality and on their character of institutional acts, I'll show that the same types of constitutive rules underlying illocutionary acts also underlie institutional reality. I’ll then argue that we can derive a specific set of normative criteria for the rational criticizability of institutional acts from these constitutive rules in the same way that we can derive normat…
Search, Nash bargaining and rule-of-thumb consumers
2011
Abstract This paper analyses the effects of introducing two typical Keynesian features, namely rule-of-thumb (RoT) consumers and consumption habits, into a standard labour market search model. RoT consumers use the margin that hours and wage negotiation provides them to improve their lifetime utility, by narrowing the gap in utility with respect to Ricardian consumers. This margin for intertemporal optimisation has not been studied yet, because this class of restricted agents has been mainly used in models with no equilibrium unemployment. Our approach allows for a deeper study of the effects of shocks on vacancies, unemployment, hours, wages and how they interact. As habits increase, RoT c…
LA CONTRATTAZIONE COLLETTIVA NEGLI STATI UNITI DAL WAGNER ACT AI NOSTRI GIORNI
2016
LA CONTRATTAZIONE COLLETTIVA NEGLI STATI UNITI. DAL WAGNER ACT AI NOSTRI GIORNI. — Riassunto. Il presente lavoro analizza la legislazione statunitense in materia di contrattazione collettiva sin dall’emanazione del Wagner Act nel 1935. Al riguardo, vengono discusse le regole per il riconoscimento dei sindacati nei luoghi di lavoro e per la stipula degli accordi collettivi (principio di maggioranza e rappresentanza esclusiva, obbligo di negoziare secondo buona fede) e per la gestione del conflitto industriale (arbitrato e clausola di tregua): sulla scorta di un approccio storico-critico e dei leading case giurisprudenzialil’articolosottolineailcarattereprettamenteaziendaleeprivatisticodellere…
Insights from the genome of the biotrophic fungal plant pathogen Ustilago maydis.
2006
Ustilago maydis is a ubiquitous pathogen of maize and a well-established model organism for the study of plant-microbe interactions. This basidiomycete fungus does not use aggressive virulence strategies to kill its host. U. maydis belongs to the group of biotrophic parasites (the smuts) that depend on living tissue for proliferation and development. Here we report the genome sequence for a member of this economically important group of biotrophic fungi. The 20.5-million-base U. maydis genome assembly contains 6,902 predicted protein-encoding genes and lacks pathogenicity signatures found in the genomes of aggressive pathogenic fungi, for example a battery of cell-wall-degrading enzymes. Ho…
Electromagnetic mass difference of pions at low temperature
1999
We compute low temperature corrections to the electromagnetic mass difference of pions in the chiral limit. The computation is done in a model independent way in the framework of chiral perturbation theory, using the background field method and the hard thermal loop approximation. We also generalize at low temperature the sum rule of Das et al. We find that the mass difference between the charged and neutral pions decreases at low temperature $T$ with respect to the T=0 value. This is so in spite of the fact that charged particles always get a thermal correction to their masses of order $\sim eT$, where $e$ is the gauge coupling constant. Our result can be understood as a consequence of the…
Radiative muon capture and the value of gP in nuclei
1990
Abstract Radiative muon capture by nuclei is analyzed by means of sum rule techniques, providing a total photon yield calculated with RPA precision. The measured yields relative to the ordinary muon capture rate are well reproduced for the nuclei 12C, 16O and 40Ca using a value of the pseudoscalar weak coupling constant gP enhanced by only 25% with respect to its canonical value. Therefore, the large renormalization of gP claimed up to now must be reconsidered.
Pentaquark decay width in QCD sum rules
2005
In a diquark-diquark-antiquark picture of the pentaquark we study the decay $\Theta \rightarrow K^{+} n$ within the framework of QCD sum rules. After evaluation of the relevant three-point function, we extract the coupling $g_{\Theta nK}$ which is directly related to the pentaquark width. Restricting the decay diagrams to those with color exchange between the meson-like and baryon-like clusters reduces the coupling constant by a factor of four. Whereas a small decay width might be possible for a positive parity pentaquark, it seems difficult to explain the measured width for a pentaquark with negative parity.
High prevalence of oral potentially malignant disorders and risk factors in a semi-urban brazilian city: a population-based cross-sectional study
2021
Background Oral Potentially Malignant Disorders (OPMDs) are defined as lesions with a greater likelihood of progressing to cancer. Population-based studies that evaluate the prevalence of OPMDs are scarce in Brazil. The aim of the present study was to determine the prevalence of OPMDs and associated risk factors in a semi-urban Brazilian population. Material and Methods This is a cross-sectional study, whose universe included individuals aged 40 years or older residing in a medium-sized city of northeastern Brazil. Data collection was divided into two steps: interview and oral examination. The outcome variable was the presence of OPMDs. The predictor variables were sociodemographic characte…
