Jet Physics at Tevatron
An overview of Run I jet physics at the ppbar Fermilab Tevatron Collider with
a particular emphasis on inclusive jet cross section measurements is given. The
impact of these studies on PDFs constrain from global fits is underlined.
Preliminary results on inclusive jet and di-jet mass cross section measurements
in Run II are then summarized.Comment: Presented at 15th Conference on High-Energy Physics (IFAE 2003),

QCD Physics at the Tevatron
Results on recent QCD measurements performed at the Tevatron ppbar Collider
at sqrt{s} = 1.96 TeV are here reported. The inclusive jet and dijet mass cross
sections are compared to NLO pQCD calculations and to Run I results. The
production rates and kinematic properties of W + jets production processes are
compared to ``enhanced'' LO theoretical predictions. Non-perturbative ``soft''
interactions leading to the underlying event are studied and compared to QCD
Monte Carlo phenomenological models.Comment: Presented at 18th Les Rencontres De Physique De La Vallee D'Aoste:

The TOTEM Experiment at LHC
The TOTEM experiment at the CERN LHC is here presented. After an overview of
the experimental apparatus, the measurement of the total pp cross section,
elastic scattering and diffractive phenomena is described. This physics
programme will allow to distinguish among different models of soft proton
interactionsComment: Presented at 22nd Les Rencontres de Physique de la Vallee d'Aoste,

Bridging Community, Research, and Action: An Emerging Center on Latino Youth Development (FOCUS)
This NCCD FOCUS is an update on the community conversations held across California with Latino community stakeholders on the status of Latino youth and the creation of a Center on Latino Youth Development
The TOTEM Experiment at the LHC
The TOTEM experiment at the LHC is dedicated to the measurement of the total
pp cross section and to the study of elastic scattering and of diffractive
dissociation processes. TOTEM is here presented with a general overview on the
main features of its experimental apparatus and of its physics programme.Comment: Proceedings of XLIIIth Rencontres de Moriond - QCD session, La Thuile

Measurement of the Bottom-Strange Meson Mixing Phase in the Full CDF Data Set
We report a measurement of the bottom-strange meson mixing phase \beta_s
using the time evolution of B0_s -> J/\psi (->\mu+\mu-) \phi (-> K+ K-) decays
in which the quark-flavor content of the bottom-strange meson is identified at
production. This measurement uses the full data set of proton-antiproton
collisions at sqrt(s)= 1.96 TeV collected by the Collider Detector experiment
at the Fermilab Tevatron, corresponding to 9.6 fb-1 of integrated luminosity.
We report confidence regions in the two-dimensional space of \beta_s and the
B0_s decay-width difference \Delta\Gamma_s, and measure \beta_s in [-\pi/2,
-1.51] U [-0.06, 0.30] U [1.26, \pi/2] at the 68% confidence level, in
agreement with the standard model expectation. Assuming the standard model
value of \beta_s, we also determine \Delta\Gamma_s = 0.068 +- 0.026 (stat) +-
0.009 (syst) ps-1 and the mean B0_s lifetime, \tau_s = 1.528 +- 0.019 (stat) +-
0.009 (syst) ps, which are consistent and competitive with determinations by
other experiments.Comment: 8 pages, 2 figures, Phys. Rev. Lett 109, 171802 (2012
The Latino Vote in the 2010 Elections
Compares the Latino/Hispanic vote in the 2010 midterm elections with 2006 and with African-American and white voters, with a focus on Latino/Hispanic candidates and states with large Latino/Hispanic communities
Cultivating Contextual Attributes in the Integration of Latin@ Educational Leadership
Although the Latino population is growing rapidly in the United States, there is a disproportionate paucity of literature on the perspectives and challenges of Latino/a educational leaders. Culturally aware educational leadership can help to improve retention and student engagement of Latino students. The purpose of this article is to explore the factors influencing the educational experience and perspective of Latino/a students and leaders to expand the understanding of Latinos within the education system. Identifying role models, creating network and professional development opportunities, as well as offering training programs are practices to enhance the training and expertise of Latino educational leaders. Implications and recommendations for practice and research are discussed
