  • Cumulative victimization, psychological distress, and high-risk behavior among substance-involved women.
    Violence & Victims, 2011
    Co-Authors: Seana Golder, Tk Logan

    Abstract:

    This research addressed two questions: (a) What is the relationship between different patterns of cumulative victimization and psychological distress? And (b) How does the pattern of cumulative victimization and psychological distress influence women’s engagement in substance- and sex-related risk behavior? Data were analyzed from interviews with 149 sexually Active, Crack-using women who completed a follow-up interview after participating in the Kentucky National Institute on Drug Abuse (NIDA) AIDS Cooperative Agreement. Findings from the multivariate analyses indicated that victimization accounted for 5% and 39% of the variance in psychological distress and high-risk behavior, respectively; cumulative victimization and psychological distress accounted for 6% to 11% of the variance in the high-risk behaviors. Results highlight the affects of childhood and adult victimization on psychological distress and the associations between different types of psychological distress and risk behavior.

  • Correlates and Predictors of Women’s Sex Trading Over Time among a Sample of Out-of-treatment Drugs Abusers
    AIDS and Behavior, 2007
    Co-Authors: Seana Golder, Tk Logan

    Abstract:

    This research addressed two research questions: (a) controlling for Crack use, what are the factors associated with women’s engagement in ever having traded sex? and (b) controlling for Crack use, what are the factors associated with women’s engagement in sex trading in the past 90 days? The sample included 149 sexually Active, Crack using women selected from a subsample of participants in the Kentucky NIDA AIDS Cooperative Agreement. Bivariate analyses indicated that in addition to the pattern of Crack use, 13 of the candidate variables were significantly related to sex trading, ever and 11 related to sex trading in the past 90 days. The multivariate models accounted for more than 40% of the variance in sex trading, ever and almost 59% of the variance in sex trading over the past 90 days. Suggestions for HIV/AIDS prevention and intervention among drug-involved women are discussed; implications for future research are suggested.

  • An architecture for real-time arbitrary and variable sampling rate conversion with application to the processing of harmonic signals
    , 2020
    Co-Authors: Galindo Guarch, Francisco Javie, Audrenghie Philippe, Moreno Arostegui, Jua Manuel

    Abstract:

    The paper presents a new solution for sampling rate conversion and processing of harmonic signals with known but possibly varying fundamental frequency. This problem is commonly found in particle accelerators, for tracking the beam signals whose revolution frequency varies during the acceleration ramp. It is also common among many other fields such as speech and music processing, removal of mechanical noises, filtering of biomedical recordings, Active Crack imaging, etc. The key element in the proposed solution is a new architecture for a Farrow-based resampler, in which the resampling ratio can take any value and can be modified continuously to follow the signal fundamental frequency. The combination of two complementary resamplers creates a processing region where signal synchronous processing is performed. The resampler architecture is optimized for modern FPGA features. It decouples the processing and sampling clocks, and uses a single processing (hardware) clock whose frequency remains fixed. The functional model was migrated to Xilinx System Generator and the overall performance is evaluated with an application that filters a periodic signal whose frequency follows a known linear ramp in the presence of additive white noise.The authors would like to thank CERN colleagues in BE-RF-FB section, plus K. Smith’s group at BNL, T. Mastoridis at California Polytechnic State University, C. Rivetta at SLAC and F. Tamura from J-PARC for the many fruitful discussions. Special thanks to A. Butterworth and R. Borner at CERN BE-RF for proofreading the paper.Peer Reviewe
