    We define a morphism based upon a Latin square that generalizes the Thue-Morse morphism. We prove that fixed points of this morphism are overlap-free sequences generalizing results of Allouche - Shallit and Frid.Comment: 5 pages, 1 figur

    Near Earth Space Object Detection Utilizing Parallax as Multi-hypothesis Test Criterion

    The US Strategic Command (USSTRATCOM) operated Space Surveillance Network (SSN) is tasked with Space Situational Awareness (SSA) for the US military. This system is made up of Electro-Optic sensors such as the Space Surveillance Telescope (SST) and Ground-based Electro-Optical Deep Space Surveillance (GEODSS) as well as RADAR based sensors such as the Space Fence. While Lockheed Martin’s Space Fence is very adept at detecting & tracking objects in Low Earth Orbit (LEO) below 3000 Km in height [1], gaps remain in the tracking of Resident Space Objects (RSO’s) in Geosynchronous Orbits (GEO) due to limitations associated with the implementation of the SST and GEODSS systems. This thesis explores a reliable, ground-based technique to quickly determine the altitude of a RSO from a single or limited set of observations; implementation of such sensors into the SSN would mitigate GEO SSA performance gaps. The research entails a method to distinguish between the point spread function (PSF) observed by a star and the PSF observed from an RSO using Multi-Hypothesis Testing with parallax as a test criterion. Parallax is the effect that an observed object will appear to shift when viewed from different positions. This effect is explored by generating PSFs from telescope observations of space objects at different baselines. The research has shown the PSF of an RSO can be distinguished from that of a star using single, simultaneous observations from reference and parallax sensing telescopes. This thesis validates these techniques with both simulations and with experimental data from the SST and Naval Observatory sensors

    Life under Union Occupation: Elite Women in Richmond, April and May 1865

    Get PDF
    This paper crafts a narrative about how elite, white Richmond women experienced the fall and rebuilding of their city in April and May 1865. At first, the women feared the entrance of the occupying army because they believed the troops would treat them as enemies. However, the goal of the white occupiers was to restore order in the city. Even though they were initially saddened by the occupation, many women were surprised at the courtesy and respected afforded them by the Union troops. Black soldiers also made up the occupying army, and women struggled to submit to black authority. With occupation came the emancipation of slaves, and this paper also examines how women adjusted to new relationships with freed blacks. By the end of May, white women and white Union soldiers bonded over their attempt to control the black population, with some women and soldiers even beginning to socialize

    Working for Change: Gender Inequality in the Labor Force in Japan, South Korea, and Taiwan

    Gender inequality in the labor force is a persistent global problem. Because equality in labor is thought to be key to reversing overall gender inequality, attention to factors affecting the status of women in the labor force (the gender wage gap, female labor force participation, occupational sex segregation, etc.) is crucial to addressing overall gender inequality. Though the effects of labor force inequality are more visible in the culturally similar, highly industrialized, and otherwise highly developed countries of East Asia than in the West, the contrast in the conditions of these indicative factors among Japan, South Korea, and Taiwan may provide important insights into narrowing the gender gap. Significantly, Taiwan, with an economy dominated by small and medium sized enterprises, political gender quotas, and an active women’s movement, is found to have relatively more success in eliminating inequality and possesses a more gender equal labor force

    Reducing Stigma toward the Transgender Community: An Evaluation of a Humanizing and Perspective-Taking Intervention

    Get PDF
    Transgender (TG) individuals are an understudied group at high risk of experiencing discrimination and associated adverse mental health outcomes (IOM, 2011). Although many studies demonstrate that contact reduces negative attitudes toward out-groups, few studies have examined the link between contact and attitudes toward the TG community (Hill & Willoughby, 2005; Walchet al., 2012). This study represents one of the first attempts to understand how to effectively reduce stigma toward the TG community. Results indicate that education alone is not enough to change attitudes; in fact, there is some evidence that associating transgenderism with psychopathology may heighten stigma. Consistent with prior research on stigma towards the mentally ill, the current study suggests that both exposure to intimate media depictions of the “other” (Reinke et al., 2004) and perspective-taking (Mann & Himelein, 2008) could strengthen educational campaigns designed to combat stigma

    Selfie-Objectification: Does Taking One’s Own Picture Increase Levels of State Self-Objectification among College Females?

    Get PDF
    The current experiment investigated the effects of taking a selfie on self-objectification. In the experiment, 107 women either took 5 selfies, unlimited selfies, had 5 photos taken of them, or had no photos taken. Participants completed an Objectified Body Consciousness Scale and 10 “I am” statements, which were coded for self-objectification. Women in the unlimited selfie condition made more appearance-based self-statements than those whose photos were not taken

    Oregon Psychologists on Prescriptive Authority: Divided Views and Little Knowledge

    Get PDF
    With over half of all states having considered legislating prescriptive authority, an immense amount of time and money has been invested. The literature is limited in terms of understanding if opinions toward prescriptive authority are grounded in knowledge and what implications that has for altering these opinions. Following a veto of a prescriptive authority bill in Oregon, 399 licensed Oregon clinical psychologists were surveyed regarding their attitudes and knowledge. In terms of knowledge, only 6.5% knew which three states/territories currently have prescriptive authority and 70.4% were unfamiliar with any of the prerequisites for postdoctoral training in psychopharmacology. Reflecting division, 43.4% were in favor, 25.4% were undecided, and 31.2% were in opposition to broadening privileges for psychologists. Further, only 15.2% expressed interest in pursuing training or 6.7% in becoming prescribers. Data on access, training, and legislative costs were presented to participants in the education condition. These participants showed significant gains in their knowledge across all domains and their opinions shifted only in these specific areas leaving their general stance on the issue unchanged. In contrast to ardent supporters who argue that their “data should provide reassurance to psychologists spearheading legislative initiatives” because of high approval ratings (Sammons et al., 2000, p. 608), our data suggest disagreement amongst a group of professionals who are not particularly well-informed, nor interested in becoming prescribers. Future work should investigate whether expanding the data relevant to other facets of the argument contributes to further targeted change or an overall change in opinion toward prescriptive authority
