    College-aged women are within the highest risk group of women (18 to 25 years old) to experience sexual assault. Nineteen percent of college women report experiencing attempted or completed sexual assault during their four years of college (Krebs, Linquist, Warner, Fisher, & Martin, 2009). It is estimated that 20 to 25% of college women will experience an attempted or completed sexual assault during college (American College Health Association, 2008). The primary sexual assault prevention method on college campuses has been in the form of education (Centers for Disease Control and Prevention, 2004) with an emphasis on debunking commonly held false attitudes and beliefs about rape, or “rape myths,” that historically blame victims and vindicate perpetrators of sexual assault (Brownmiller, 1975; Burt, 1980). The use of rape myth acceptance (RMA) measures has played an important role in sexual assault research. Measurement problems in older RMA measures, however, have been noted, (Gerger, Kley, Bohner, & Siebler, 2007) making it unclear how accurately older RMA measures are capturing RMA levels. The Acceptance of Modern Myths about Sexual Aggression (AMMSA) scale, a newer measure, offers more robust psychometric properties than older RMA measures that may serve to improve the efficacy of campus sexual assault prevention interventions. The primary purpose of this study was to explore the psychometric properties of the AMMSA scale with a Southeastern U.S. college sample. The secondary purpose of the study was to compare levels of RMA between female sexual assault victims and non-victims and to examine whether the associations between RMA and sociocultural attitudes depend upon victimization status. Participants in the study included 367 undergraduate students who anonymously completed an online survey. Results indicated that the AMMSA scale demonstrates good psychometric properties. Female victims and non-victims scored similarly in RMA and sociocultural attitudes. Multiple regression analyses indicated that the relationships between the AMMSA scale and the sociocultural variables did not depend upon victimization status. This study provides important implications for researchers conducting sexual assault prevention research and for clinicians working with victims and their families

    Rhythms of Locomotion Expressed by Limulus polyphemus, the American Horseshoe Crab: II. Relationship to Circadian Rhythms of Visual Sensitivity

    In the laboratory, horseshoe crabs express a circadian rhythm of visual sensitivity as well as daily and circatidal rhythms of locomotion. The major goal of this investigation was to determine whether the circadian clock underlying changes in visual sensitivity also modulates locomotion. To address this question, we developed a method for simultaneously recording changes in visual sensitivity and locomotion. Although every animal (24) expressed consistent circadian rhythms of visual sensitivity, rhythms of locomotion were more variable: 44% expressed a tidal rhythm, 28% were most active at night, and the rest lacked statistically significant rhythms. When exposed to artificial tides, 8 of 16 animals expressed circatidal rhythms of locomotion that continued after tidal cycles were stopped. However, rhythms of visual sensitivity remained stable and showed no tendency to be influenced by the imposed tides or locomotor activity. These results indicate that horseshoe crabs possess at least two biological clocks: one circadian clock primarily used for modulating visual sensitivity, and one or more clocks that control patterns of locomotion. This arrangement allows horseshoe crabs to see quite well while mating during both daytime and nighttime high tides

    Spacelab Data Processing Facility (SLDPF) expert system prototypes were developed to assist in the quality assurance of Spacelab and/or Attached Shuttle Payload (ASP) processed telemetry data. The SLDPF functions include the capturing, quality monitoring, processing, accounting, and forwarding of mission data to various user facilities. Prototypes for the two SLDPF functional elements, the Spacelab Output Processing System and the Spacelab Input Processing Element, are described. The prototypes have produced beneficial results including an increase in analyst productivity, a decrease in the burden of tedious analyses, the consistent evaluation of data, and the providing of concise historical records

    An Evaluation of PACER

    Get PDF
    This study evaluates the Public Access to Court Electronic Records system, otherwise known as PACER. PACER is a computerized database of federal court documents, administered by the Administrative Office of the United States Courts. This paper will cover the history of public access to electronic court records and the issues and controversies surrounding PACER. Controversies include the US Courts charging the public fees for accessing information that belongs to the public, the privacy concerns with making court documents available on the internet, the difficulty in citing court records, the authentication challenge with PACER documents and the difficulty of using PACER as a legal research tool. In addition to the controversies, PACER's page layout, navigation and search capability will be evaluated using government guidelines for evaluation

    Aquaporin proteins in murine trophectoderm mediate transepithelial water movements during cavitation.

    Mammalian blastocyst formation is dependent on establishment of trophectoderm (TE) ion and fluid transport mechanisms. We have examined the expression and function of aquaporin (AQP) water channels during murine preimplantation development. AQP 3, 8, and 9 proteins demonstrated cell margin-associated staining starting at the 8-cell (AQP 9) or compacted morula (AQP 3 and 8) stages. In blastocysts, AQP 3 and 8 were detected in the basolateral membrane domains of the trophectoderm, while AQP3 was also observed in cell margins of all inner cell mass (ICM) cells. In contrast, AQP 9 was predominantly observed within the apical membrane domains of the TE. Murine blastocysts exposed to hyperosmotic culture media (1800 mOsm; 10% glycerol) demonstrated a rapid volume decrease followed by recovery to approximately 80% of initial volume over 5 min. Treatment of blastocysts with p-chloromercuriphenylsulfonic acid (pCMPS, \u3e or =100 microM) for 5 min significantly impaired (P \u3c 0.05) volume recovery, indicating the involvement of AQPs in fluid transport across the TE. Blastocysts exposure to an 1800-mOsm sucrose/KSOMaa solution did not demonstrate volume recovery as observed following treatment with glycerol containing medium, indicating glycerol permeability via AQPs 3 and 9. These findings support the hypothesis that aquaporins mediate trans-trophectodermal water movements during cavitation

    Maintaining human wellbeing as socio-environmental systems undergo regime shifts

    Global environmental change is pushing many socio-environmental systems towards critical thresholds, where ecological systems' states are on the precipice of tipping points and interventions are needed to navigate or avert impending transitions. Flickering, where a system vacillates between alternative stable states, is touted as a useful early warning signal of irreversible transitions to undesirable ecological regimes. However, while flickering may presage an ecological tipping point, these dynamics also pose unique challenges for human adaptation. In this work, we link an ecological model that can exhibit flickering to a model of human adaptation to a changing environment. This allows us to explore the impact of flickering on the utility of adaptive agents in a coupled socio-environmental system. We highlight the conditions under which flickering causes wellbeing to decline disproportionately, and explore how these dynamics impact the optimal timing of a transformational change that partially decouples wellbeing from environmental variability. The implications of flickering on nomadic communities in Mongolia, artisanal fisheries, and wildfire systems are explored as possible case studies. Flickering, driven in part by climate change and changes to governance systems, may already be impacting communities. We argue that governance interventions investing in adaptive capacity could blunt the negative impact of flickering that can occur as socio-environmental systems pass through tipping points, and therefore contribute to the sustainability of these systems

    Reduced receptor editing in lupus-prone MRL/lpr mice

    The initial B cell repertoire contains a considerable proportion of autoreactive specificities. The first major B cell tolerance checkpoint is at the stage of the immature B cell, where receptor editing is the primary mode of eliminating self-reactivity. The cells that emigrate from the bone marrow have a second tolerance checkpoint in the transitional compartment in the spleen. Although it is known that the second checkpoint is defective in lupus, it is not clear whether there is any breakdown in central B cell tolerance in the bone marrow. We demonstrate that receptor editing is less efficient in the lupus-prone strain MRL/lpr. In an in vitro system, when receptor-editing signals are given to bone marrow immature B cells by antiidiotype antibody or after in vivo exposure to membrane-bound self-antigen, MRL/lpr 3-83 transgenic immature B cells undergo less endogenous rearrangement and up-regulate recombination activating gene messenger RNA to a lesser extent than B10 transgenic cells. CD19, along with immunoglobulin M, is down-regulated in the bone marrow upon receptor editing, but the extent of down-regulation is fivefold less in MRL/lpr mice. Less efficient receptor editing could allow some autoreactive cells to escape from the bone marrow in lupus-prone mice, thus predisposing to autoimmunity
