Addressing Disparities for Gambling Treatment Service Use in the Latinx Community: Outreach, Education, Screening, and Referral by Community Health Workers
ABSTRACT
Problem gambling/gambling disorder prevalence among Latinx individuals in the U.S. is similar to that seen in the non-Latinx Caucasian community (Alegria et al., 2009). However, there are disparities in the use of State-funded treatment for such problems in California. This is true for mental health service use for ethnic/racial minorities in the US overall (Alegria et al., 2008; Dua et al., 2011; Wells et al., 2001). The California Office of Problem Gambling (OPG), the UCLA Gambling Studies Program (UGSP), and VisiĆ³n y Compromiso (VyC) are conducting a 2-year pilot project using community health workers (promotores/as) to increase Latinx utilization of CalGETS services in Los Angeles and San Diego Counties. The proximal goal of this project is to implement/evaluate a culturally/linguistically relevant enhancement to program outreach activities. Progress to date includes: (1) a Spanish-language translation of the Breif Biosocial Gambling Screen; (2) focus group data on gambling in the Latinx community; (3) a two-day, gambling-specific Spanish-language training for promotores/as; (4) measures of trainee satisfaction and knowledge; (5) a Spanish-language field guide for promotores/as; and, (6) about 27 trained promotores/as. The distal goal of this work is to create content that is adaptable to other underserved communities in the U.S.
IMPLICATIONS
State-funded gambling treatment must serve an increasingly diverse population in the U.S. This project may be the first to use promotores/as to address cultural/linguistic gaps in services for Latinx persons. It may help to inform similar work other States and for other underserved communities in the U.S

Search for dark matter in association with a Higgs boson decaying to b-quarks in pp collisions at s=13 TeV with the ATLAS detector
A search for dark matter pair production in association with a Higgs boson decaying to a pair of bottom quarks is presented, using 3.2 fbā1 of pp collisions at a centre-of-mass energy of 13 TeV collected by the ATLAS detector at the LHC. The decay of the Higgs boson is reconstructed as a high-momentum bbĀÆ system with either a pair of small-radius jets, or a single large-radius jet with substructure. The observed data are found to be consistent with the expected backgrounds. Results are interpreted using a simplified model with a Zā² gauge boson mediating the interaction between dark matter and the Standard Model as well as a two-Higgs-doublet model containing an additional Zā² boson which decays to a Standard Model Higgs boson and a new pseudoscalar Higgs boson, the latter decaying into a pair of dark matter particles
Search for resonances in the mass distribution of jet pairs with one or two jets identified as b-jets in protonāproton collisions at s=13Ā TeV with the ATLAS detector
Ā© 2016 The AuthorSearches for high-mass resonances in the dijet invariant mass spectrum with one or two jets identified as b-jets are performed using an integrated luminosity of 3.2Ā fbā1 of protonāproton collisions with a centre-of-mass energy of s=13Ā TeV recorded by the ATLAS detector at the Large Hadron Collider. No evidence of anomalous phenomena is observed in the data, which are used to exclude, at 95% credibility level, excited bā quarks with masses from 1.1 TeV to 2.1 TeV and leptophobic Zā² bosons with masses from 1.1 TeV to 1.5 TeV. Contributions of a Gaussian signal shape with effective cross sections ranging from approximately 0.4 to 0.001 pb are also excluded in the mass range 1.5ā5.0 TeV

Z boson production in Pb+Pb collisions at āSnn = 5.02 TeV measured by the ATLAS experiment
The production yield of Z bosons is measured in the electron and muon decay channels in Pb+Pb collisions at āS = 5.02 TeV with the ATLAS detector. Data from the 2015 LHC run corresponding to an integrated luminosity of 0.49 nb are used for the analysis. The Z boson yield, normalised by the total number of minimum-bias events and the mean nuclear thickness function, is measured as a function of dilepton rapidity and event centrality. The measurements in Pb+Pb collisions are compared with similar measurements made in proton-proton collisions at the same centre-of-mass energy. The nuclear modification factor is found to be consistent with unity for all centrality intervals. The results are compared with theoretical predictions obtained at next-to-leading order using nucleon and nuclear parton distribution functions. The normalised Z boson yields in Pb+Pb collisions lie 1-3Ļ above the predictions. The nuclear modification factor measured as a function of rapidity agrees with unity and is consistent with a next-to-leading-order QCD calculation including the isospin effect. nn -
Search for flavour-changing neutral currents in processes with one top quark and a photon using 81 fbā1 of pp collisions at s=13TeV with the ATLAS experiment
A search for flavour-changing neutral current (FCNC) events via the coupling of a top quark, a photon, and an up or charm quark is presented using 81 fbā1 of protonāproton collision data taken at a centre-of-mass energy of 13 TeV with the ATLAS detector at the LHC. Events with a photon, an electron or muon, a b-tagged jet, and missing transverse momentum are selected. A neural network based on kinematic variables differentiates between events from signal and background processes. The data are consistent with the background-only hypothesis, and limits are set on the strength of the tqĪ³ coupling in an effective field theory. These are also interpreted as 95% CL upper limits on the cross section for FCNC tĪ³ production via a left-handed (right-handed) tuĪ³ coupling of 36 fb (78 fb) and on the branching ratio for tāĪ³u of 2.8Ć10ā5 (6.1Ć10ā5). In addition, they are interpreted as 95% CL upper limits on the cross section for FCNC tĪ³ production via a left-handed (right-handed) tcĪ³ coupling of 40 fb (33 fb) and on the branching ratio for tāĪ³c of 22Ć10ā5 (18Ć10ā5)
