Measurements of CP-Violating Asymmetries in B0 to a1(1260)^{+-} pi^{-+} Decays
We present measurements of CP-violating asymmetries in the decay B0 ->
a_1(1260)^{+-} pi^{-+} with a_1(1260)^{+-} -> pi^{-+} pi^{+-} pi^{+-}. The data
sample corresponds to 384 million B B-bar pairs collected with the BaBar
detector at the PEP-II asymmetric B-factory at SLAC. We measure the
CP-violating asymmetry A^{a1pi}_{CP}=-0.07+-0.07+-0.02, the mixing-induced CP
violation parameter S_{a1pi}= 0.37 +-0.21+-0.07, the direct CP violation
parameter C_{a1pi}=-0.10+-0.15+-0.09, and the parameters
DeltaC_{a1pi}=0.26+-0.15+-0.07 and DeltaS_{a1pi}=-0.14+-0.21+-0.06. From these
measured quantities we exstract the angle alpha_{eff}= 78.6^{0} +- 7.3^{0}.Comment: 4 pages, 2 postscript figures Invited talk at the 4th International

B Decays and CP Violation from BaBar
We present some recent BABAR measurements of the magnitudes of the elements
Vub and Vcb of the Cabibbo-Kobayashi-Maskawa quark-mixing matrix, and of the
angles alpha and gamma of the unitary triangle of the standard model of the
electroweak interactions. Most of the measurements presented here are based on
the full BABAR Y(4S) dataset, consisting of about 467 million B anti-B pairs.Comment: 16 pages, 10 eps figures, invited talk presented at the 8th Latin

Searches for New Physics in CP Violation from BaBar
Results of recent searches for new physics in CP violation in charm decays
from the BABAR experiment are presented. These results include a measurement of
- mixing and searches for CP violation in two-body
decays, a search for CP violation in the charm decays and , , and a search for
direct CP violation in the singly-Cabibbo suppressed decays. These studies are based on the final dataset collected by
BABAR at the PEP-II B factory at SLAC in the period 1999-2008. No evidence of
CP violation is found in these charm decays. The measured mixing parameter
% excludes the no-mixing null
hypothesis with a significance of 3.3.Comment: 9 pages, 5 pdf figures, contributed to the Proceedings of

The argali (Ovis ammon antiqua) from the Magliana area (Rome)
During the Middle Pleistocene, the subspecies was widespread from Georgia to Portugal, though it is scantily recorded in local faunal assemblages of Southern Europe. Its occurrence in a few Late Pleistocene sites needs to be confirmed. In Italy, the subspecies is recorded in the late Galerian fauna of Visogliano (MIS 13 - 10) as well as in the Magliana area, where an incomplete skull was found at the beginning of the last century. Although the precise location where this specimen was found is unknown, on the basis of the results of the geochemical analysis performed on a small amount of sediment, sampled from the filling of the inner cavities of the horn-cores, and considering the stratigraphy of the area, the hypothesis that the skull comes from the deposits of the PG4 sequence (MIS14 partim - MIS13) cannot be ruled out. This hypothetical remark would confirm the occurrence in Italy of the argali in late Galerian faunas. The dimensions of Ovis ammon antiqua from the Magliana area fit well within the range of variability of the larger specimens, likely males, found at La Caune de L’Arago (France) (MIS 14-12), from which the Italian specimen differs in having less twisted and more dorso-ventrally curved horn-cores
Verso l'istituzione della Procura europea: dal Corpus Juris alla proposta di regolamento COM(2013) 534
Il 17 luglio 2013 la Commissione ha presentato la proposta di regolamento istitutiva della Procura europea, il cui compito è la tutela degli interessi finanziari dell'Unione europea. Il presente lavoro si prefigge lo scopo di analizzare lo sviluppo della figura del "pubblico ministero europeo", apparso per la prima volta nel "Corpus Juris", primo progetto di codificazione europea in materia penale. Sebbene la sua possibile istituzione ponga numerosi dubbi circa la compatibilità con i sistemi processuali dei Paesi membri, si ritiene che essa costituirà un valore aggiunto nella lotta alla criminalità internazionale
Recent CKM and CP Results from BaBar
We present recent results of B and charm decays from the BaBar experiment.
These results include searches for rare or forbidden charm decays, measurements
of from inclusive decays,
observation of the semileptonic decays, direct CP violation asymmetry in and in , and T-violation in . These studies are based on the final
dataset collected by BaBar at the PEP-II B factory at SLAC in the period
1999-2008.Comment: 16 pages, 10 pdf figures, contributed to the Proceedings of the 5th

Building Information Communication Technology Infrastructures for Economic Development
This paper analyzes the impact of Information Communication Technology (ICT) Infrastructures on economic development through a statistical analysis of data from Saint Vincent and the Grenadines, and a policy analysis of the Workforce Investment Act and Ben Franklin Technology Partners programs in Pennsylvania. In the analysis of Saint Vincent, significant relationships were found between all aspects of ICT programs and a variety of measures of economic development, with the extent of Internet subscribers showing the greatest impact. The analysis of the Pennsylvania programs found that technology-oriented workforce education programs are only successful when there is a demand for related labor skills in the job market. The overall recommendation of this paper is to continue ICT development initiatives while also developing policies that promote collaboration between the public and private sectors, promote development of new technology-based businesses, and assess technology-oriented labor needs
