    Sex and God #blesses: the relationship between faith and reported frequency of hooking-up among college students

    Hooking-up is defined as a physically intimate encounter between two individuals whom are not romantically involved with one another (Stroke; et al., 2014). Past research has shown that students who reported that religion had a higher influence on their daily life also reported hooking-up less frequently (Simons, et al., 2009). Limited research has been conducted to measure whether priming persons with their religious beliefs- has an impact on the reported frequency of sexual health practices. This research extended the paradigm of Saroglou and Munoz-Garcia (2008) who employed a technique in which they asked participants questions about their values and personality traits in differing orders. This study sought to investigate if the placement of religious-based questions had an influence on reported frequency of sexual health practices. Findings from this study revealed that there was a negative correlation within all three question placement conditions at a .05 significance level

    Solar Flare Impulsive Phase Observations from SDO and Other Observatories

    With the start of normal operations of the Solar Dynamics Observatory in May 2010, the Extreme ultraviolet Variability Experiment (EVE) and the Atmospheric Imaging Assembly (AIA) have been returning the most accurate solar XUV and EUV measurements every 10 and 12 seconds, respectively, at almost 100% duty cycle. The focus of the presentation will be the solar flare impulsive phase observations provided by EVE and AIA and what these observations can tell us about the evolution of the initial phase of solar flares. Also emphasized throughout is how simultaneous observations with other instruments, such as RHESSI, SOHO-CDS, and HINODE-EIS, will help provide a more complete characterization of the solar flares and the evolution and energetics during the impulsive phase. These co-temporal observations from the other solar instruments can provide information such as extending the high temperature range spectra and images beyond that provided by the EUV and XUV wavelengths, provide electron density input into the lower atmosphere at the footpoints, and provide plasma flows of chromospheric evaporation, among other characteristics

    The influence of riparian invasion by the terrestrial shrub Lonicera maackii on aquatic macroinvertebrates in temperate forest headwater streams

    The ecology of headwater streams is tightly linked to the riparian zone through organic matter subsidies which are highly susceptible to alteration due to biological invasion. Lonicera maackii is a non-native shrub that is a highly successful invader of headwater stream riparian zones in the American Midwest. We assessed effects on benthic macroinvertebrates across a gradient of invasion intensity from references sites with minimal invasion to a site that had a very heavy invasion. Benthic macroinvertebrates were sampled throughout the year and compositional differences were assessed using Non-metric Multidimensional Scaling ordination, and by comparing the prevalence of sensitive (Ephemeroptera, Plectoptera, and Trichoptera: EPT) and tolerant (Chironomidae) macroinvertebrate taxa. We found strong evidence of variation among macroinvertebrate communities across the invasion gradient (ANOSIM R = 0.215, P = 0.004) and particularly strong separation between one of our reference sites with minimal invasion and the site with the heaviest invasion. Analysis of EPT taxa indicated a significant overall effect and pairwise comparisons indicated that the site with the heaviest invasion had the lowest percentage of sensitive taxa (P \u3c 0.05). Our analysis of chironomids did not yield a statistically discernable effect, although the pattern of the data suggest higher dominance in the site with the heaviest invasion. These stream-scale results bolster prior laboratory and field experiments and provide evidence that terrestrial invasion of L. maackiiimpacts the benthic community present in headwater streams. These results provide impetus to re-focus stream management recommendations to include practices that control invasive plants in riparian forests

    Validation of Results from Knowledge Discovery: Mass Density as a Predictor of Breast Cancer

    The purpose of our study is to identify and quantify the association between high breast mass density and breast malignancy using inductive logic programming (ILP) and conditional probabilities, and validate this association in an independent dataset. We ran our ILP algorithm on 62,219 mammographic abnormalities. We set the Aleph ILP system to generate 10,000 rules per malignant finding with a recall >5% and precision >25%. Aleph reported the best rule for each malignant finding. A total of 80 unique rules were learned. A radiologist reviewed all rules and identified potentially interesting rules. High breast mass density appeared in 24% of the learned rules. We confirmed each interesting rule by calculating the probability of malignancy given each mammographic descriptor. High mass density was the fifth highest ranked predictor. To validate the association between mass density and malignancy in an independent dataset, we collected data from 180 consecutive breast biopsies performed between 2005 and 2007. We created a logistic model with benign or malignant outcome as the dependent variable while controlling for potentially confounding factors. We calculated odds ratios based on dichomotized variables. In our logistic regression model, the independent predictors high breast mass density (OR 6.6, CI 2.5–17.6), irregular mass shape (OR 10.0, CI 3.4–29.5), spiculated mass margin (OR 20.4, CI 1.9–222.8), and subject age (β = 0.09, p < 0.0001) significantly predicted malignancy. Both ILP and conditional probabilities show that high breast mass density is an important adjunct predictor of malignancy, and this association is confirmed in an independent data set of prospectively collected mammographic findings

    An Outbreak of Rift Valley Fever in Northeastern Kenya, 1997-98

    Get PDF
    In December 1997, 170 hemorrhagic fever-associated deaths were reported in Carissa District, Kenya. Laboratory testing identified evidence of acute Rift Valley fever virus (RVFV). Of the 171 persons enrolled in a cross-sectional study, 31(18%) were anti-RVFV immunoglobulin (Ig) M positive. An age-adjusted IgM antibody prevalence of 14% was estimated for the district. We estimate approximately 27,500 infections occurred in Garissa District, making this the largest recorded outbreak of RVFV in East Africa. In multivariate analysis, contact with sheep body fluids and sheltering livestock in one’s home were significantly associated with infection. Direct contact with animals, particularly contact with sheep body fluids, was the most important modifiable risk factor for RVFV infection. Public education during epizootics may reduce human illness and deaths associated with future outbreaks

    Bad faith in All’s Well That Ends Well

    Get PDF
    All’s Well That Ends Well is a complicated and disturbing play that has a comic ending, but which seems anything but a comedy with a forced marriage based on bed-trickery between the reluctant Bertram and the feisty and witty Helena. Unsurprisingly, audiences have tended to side with Helena and the play has been classified as a “problem comedy” ever since William Lawrence identified this particular group of Shakespeare plays nearly a century ago. I want to argue in this essay that the play might better be classified as an “equivocation” play alongside Macbeth, Othello, and Troilus and Cressida and that the anxieties about fidelity, honesty and truthfulness in marriage need to be read in terms of the fear of religious tolerance/intolerance which dominated religious politics in the early years of James’s reign before the passing of the Oath of Allegiance (1606). The play is notable for its interest in chop logic, which the clown in particular displays throughout the play, a counterpoint to the arguments of Bertram and Helena who want very different things, but who are bound together as future husband and wife. Although the language of treason and treachery is used throughout, the play is less interested in answering the question of how far one can trust a stranger within than the issue of how far one can accommodate the needs of others. This article is published as part of a collection to commemorate the 400th anniversary of William Shakespeare’s death
