- We perform simulations for future Cherenkov Telescope Array (CTA) observations of RX J1713.7-3946, a young supernova remnant (SNR) and one of the brightest sources ever discovered in very high energy (VHE) gamma rays. Special attention is paid to exploring possible spatial (anti) correlations of gamma rays with emission at other wavelengths, in particular X-rays and CO/H I emission. We present a series of simulated images of RX J1713.7-3946 for CTA based on a set of observationally motivated models for the gamma-ray emission. In these models, VHE gamma rays produced by high-energy electrons are assumed to trace the nonthermal X-ray emission observed by XMM-Newton, whereas those originating from relativistic protons delineate the local gas distributions. The local atomic and molecular gas distributions are deduced by the NANTEN team from CO and H I observations. Our primary goal is to show how one can distinguish the emission mechanism(s) of the gamma rays (i.e., hadronic versus leptonic, or a mixture of the two) through information provided by their spatial distribution, spectra, and time variation. This work is the first attempt to quantitatively evaluate the capabilities of CTA to achieve various proposed scientific goals by observing this important cosmic particle accelerator.

- Moral Foundation Theory provides a framework of understanding the underlying foundations of moral reasoning. More specifically, it is made up of five foundations that are 'intuitive ethics' representing values and norms that vary from person to person and influenced by developmental experiences. The purpose of this study was to investigate whether a relationship existed between athletic identity and the moral value preferences of collegiate athletes to shed light on the social impacts of athletic participation on college students. Two hundred and thirty-eight NCAA Division I intercollegiate, club sport, and intramural sport student-athletes completed measures of athletic identity and moral reasoning. Athletic identity was measured using the Athletic Identity Measurement Scale (AIMS) and the Moral Foundations Questionnaire (MFQ) served to evaluate participants' moral foundations. Although the primary hypothesis of a negative relationship between athletic identity and harm/care and fairness/reciprocity was not supported, analyses indicated that athletic identity was positively and significantly associated with ingroup/loyalty, authority/respect, and purity/sanctity values. Additional analyses indicated that gender and years of collegiate sporting experience moderated some of these relationships.
