Earthquake And Tsunami Forecasts: Relation Of Slow Slip Events To Subsequent Earthquake Rupture, Timothy H. Dixon, Yan Jiang, Rocco Malservisi, Robert Mccaffrey, Nicholas Voss, Marino Protti, Victor Gonzalez Dec 2014

Earthquake And Tsunami Forecasts: Relation Of Slow Slip Events To Subsequent Earthquake Rupture, Timothy H. Dixon, Yan Jiang, Rocco Malservisi, Robert Mccaffrey, Nicholas Voss, Marino Protti, Victor Gonzalez

School of Geosciences Faculty and Staff Publications

The 5 September 2012 Mw 7.6 earthquake on the Costa Rica subduction plate boundary followed a 62-y interseismic period. High-precision GPS recorded numerous slow slip events (SSEs) in the decade leading up to the earthquake, both up-dip and down-dip of seismic rupture. Deeper SSEs were larger than shallower ones and, if characteristic of the interseismic period, release most locking down-dip of the earthquake, limiting down-dip rupture and earthquake magnitude. Shallower SSEs were smaller, accounting for some but not all interseismic locking. One SSE occurred several months before the earthquake, but changes in Mohr–Coulomb failure stress were probably too small to …

Is Race A Factor In Disparate Health Problems Associated With Violence Against Women?, Marny Rivera, Gabriel Garcia

Journal Articles

Research studies examining the health correlates of violence against women have consistently demonstrated associations between violence and poor health outcomes, but have not examined a disparate impact on racial minorities. Alaska Victimization Survey data (2010) were used to examine whether a disparate relationship between victimization and health problems exists for minority women relative to White women. The Alaska Victimization Survey (AVS) is a cross-sectional survey designed to provide baseline estimates of intimate partner and sexual violence for Alaskan women. Logistic regression was used to assess the odds of experiencing various health problems given race and exposure to violence status while …

We investigate of the properties of ~2000 Herschel/SPIRE far-infrared-selected galaxies from 0 < z < 4 in the CFHTLS-D1 field. Using a combination of extensive spectroscopy from the VVDS and ORELSE surveys, deep multiwavelength imaging from CFHT, VLA, Spitzer, XMM-Newton, and Herschel, and well-calibrated spectral energy distribution fitting, Herschel-bright galaxies are compared to optically-selected galaxies at a variety of redshifts. Herschel-selected galaxies are observed to span a range of stellar masses, colors, and absolute magnitudes equivalent to galaxies undetected in SPIRE. Though many Herschel galaxies appear to be in transition, such galaxies are largely consistent with normal star-forming galaxies when rest-frame colors are utilized. The nature of the star-forming “main sequence” is studied and we warn against adopting this …

Borderline Personality Disorder And Self-Conscious Emotions In Response To Adult Unwanted Sexual Experiences, Michelle Schoenleber, Kim L. Gratz, Terri Messman-Moore, David Dilillo

Department of Psychology: Faculty Publications

Borderline personality disorder (BPD) is associated with a proneness to unpleasant self-conscious emotions (SCE). Given that BPD is also associated with heightened rates of SCE-eliciting events (including unwanted sexual experiences), research examining the factors influencing SCE in response to these events is needed. This study examined associations between BPD pathology and SCE in response to adult unwanted sexual experiences among 303 community women. Extent of sharing about and perceived personal responsibility for the event were examined as moderators of the association between BPD and current event-related SCE. Both self-reported BPD symptom severity in the full sample and interview-based measures of …

Differentiating Disclosure And Concealment In Measurement Of Outness For Sexual Minorities: The Nebraska Outness Scale, Peter C. Meidlinger, Debra A. Hope Dec 2014

Differentiating Disclosure And Concealment In Measurement Of Outness For Sexual Minorities: The Nebraska Outness Scale, Peter C. Meidlinger, Debra A. Hope

Department of Psychology: Faculty Publications

Research on lesbian, gay, and bisexual (LGB) individuals has long examined outness, or openness about one’s sexual orientation, as an important predictor of health and well-being. The authors reconceptualized outness as a composite of two related but independent constructs: disclosure and concealment of sexual orientation. This conceptualization guided creation of the Nebraska Outness Scale (NOS), a 10-item measure with a concealment (NOS-C) and disclosure (NOS-D) subscale. The scale and subscales showed good internal reliability, discriminant, convergent, and predictive validity. As hypothesized, concealment showed a stronger relationship to mental health and well-being constructs than disclosure. Disclosure, but not concealment, also differed …

Honors Theses

Schistosomiasis is a parasitic disease caused by the Schistomsoma japonicum flatworm that utilizes the Oncomelania hupensis snail as an intermediate agent. In the People’s Republic of China, these amphibious snails contaminate freshwater systems infecting humans, bovines, and other mammals and have caused significant morbidity for over two thousand years (Wertheim, et al. 2012; Zhang, et al. 2012.) The gravity of this disease prompted the national government to initiate sizable public health programs, such as the World Bank Loan Project (WBLP.) In spite of WBLP's achievements, in 2004, after this program ended, a national survey acknowledged a resurgence of schistosomiasis in …
