Korean Fashion Media, Beauty Ideals, and Colorism: Examining the Prominence of Whiteness Between 2013 and 2017 in Ceci Magazine

The purpose of this research was to critically examine fashion magazines targeted to Korean women to examine how much White or European-decent beauty ideals permeate Korean cultural outlets. In order to analyze beauty ideal representations in these fashion magazines, we utilized the content analysis method, and examined the most popular and widely circulated fashion magazine published in Korea, Ceci, from 2013-2017. Each individual pictured in the magazine was coded in five categories including: race, skin tone, hair style, hair color, and facial characteristics. Descriptive statistics, Pearson\u27s chi-square, and independent samples t-tests were utilized to analyze the data. Overall, the magazines had significantly more White- or European-decent beauty ideals throughout the imagery across the entire time period

On Identifying Points of Semantic Shift Across Domains

The semantics used for particular terms in an academic field organically evolve over time. Tracking this evolution through inspection of published literature has either been from the perspective of Linguistic scholars or has concentrated the focus of term evolution within a single domain of study. In this paper, we performed a case study to identify semantic evolution across different domains and identify examples of inter-domain semantic shifts. We initially used keywords as the basis of our search and executed an iterative process of following citations to find the initial mention of the concepts in the field. We found that a select set of keywords like ``semaphore'', ``polymorphism'', and ``ontology'' were mentioned within Computer Science literature and tracked the seminal study that borrowed those terms from original fields by citations. We marked these events as semantic evolution points. Through this manual investigation method, we can identify term evolution across different academic fields. This study reports our initial findings that will seed future automated and computational methods of incorporating concepts from additional academic fields.Comment: In 17th International Conference on Metadata and Semantics Research, October 202

Binary black hole late inspiral: Simulations for gravitational wave observations

Coalescing binary black hole mergers are expected to be the strongest gravitational wave sources for ground-based interferometers, such as the LIGO, VIRGO, and GEO600, as well as the space-based interferometer LISA. Until recently it has been impossible to reliably derive the predictions of General Relativity for the final merger stage, which takes place in the strong-field regime. Recent progress in numerical relativity simulations is, however, revolutionizing our understanding of these systems. We examine here the specific case of merging equal-mass Schwarzschild black holes in detail, presenting new simulations in which the black holes start in the late inspiral stage on orbits with very low eccentricity and evolve for ~1200M through ~7 orbits before merging. We study the accuracy and consistency of our simulations and the resulting gravitational waveforms, which encompass ~14 cycles before merger, and highlight the importance of using frequency (rather than time) to set the physical reference when comparing models. Matching our results to PN calculations for the earlier parts of the inspiral provides a combined waveform with less than half a cycle of accumulated phase error through the entire coalescence. Using this waveform, we calculate signal-to-noise ratios (SNRs) for iLIGO, adLIGO, and LISA, highlighting the contributions from the late-inspiral and merger-ringdown parts of the waveform which can now be simulated numerically. Contour plots of SNR as a function of z and M show that adLIGO can achieve SNR >~ 10 for some intermediate-mass binary black holes (IMBBHs) out to z ~ 1, and that LISA can see massive binary black holes (MBBHs) in the range 3x10^4 100 out to the earliest epochs of structure formation at z > 15.Comment: 17 pages, 20 figures.

Male hair cannot extend below plane of the shoulder and no cross dressing: Critical queer analysis of high school dress codes in the United States

With a queer theory lens, we analyzed if high school dress codes outlined in official handbooks allowed for flexibility in expression of gender and sexual identity. We used the content analysis method and analyzed public high school handbooks from the 2016-2017 school year that contained dress codes. We were interested in analyzing for emergent themes across a variety of geographic locations; therefore, handbooks were sought from five rural, five urban cluster, and five urbanized areas in each state (excluding Hawaii) resulting in analysis of 735 handbooks. In many handbooks (n = 615) the dress codes were not separated by gender. Yet, analysis of the remaining dress codes revealed the theme that there was marginalization of gender non-conforming or transgender identities or expressions. This was evident in that the dress codes were sometimes (n = 120) separated by gender with gender or sex specific terms such as ladies or guys

Social connectedness and mental well-being in transitional aged youth: A comparison between Canada and London-Middlesex region

Issue/Problem: As outlined by Mental Health Commission of Canada, one in five Canadians experience a mental illness or addiction problem at some point in their lifetime. In Canada, 70% of mental health problems have their onset during childhood or adolescence. Additionally, transitional aged youth (ages 15-24) are more likely to experience mental illness and substance use disorders than any other age group. Furthermore, adolescence and young adulthood is a time where there is an increased risk for the development of psychiatric disorders, many of which are associated with social dysfunction. Previous studies on social support and sense of belonging have shown that the structure of transitional aged youth’s relationships can have strong impacts on health and development. In order to approach this epidemic in a more holistic manner, the concept of mental well-being is gaining increasing recognition as an important health indicator. Objectives/Methods: In this proposed study, the relationship between social connectedness and mental well-being among Canadian transitional aged youth will be examined using cross-sectional data from the 2011, 2012 Annual Canadian Community Health Survey (CCHS) and also the 2012 CCHS Mental Health (MH) edition. Results: The expected completion date of the data analysis is March 2019. We expect to report on the findings related to the relationship analyzed between social connectedness and the impact it has on mental well-being. Potential impact: A better understanding of social connectedness and its association with mental well-being in transitional aged youth may allow for implementation of programs and policies that can address lack of social connectedness in London-Middlesex and across the country

Recoiling from a kick in the head-on collision of spinning black holes

Recoil ``kicks'' induced by gravitational radiation are expected in the inspiral and merger of black holes. Recently the numerical relativity community has begun to measure the significant kicks found when both unequal masses and spins are considered. Because understanding the cause and magnitude of each component of this kick may be complicated in inspiral simulations, we consider these effects in the context of a simple test problem. We study recoils from collisions of binaries with initially head-on trajectories, starting with the simplest case of equal masses with no spin and then adding spin and varying the mass ratio, both separately and jointly. We find spin-induced recoils to be significant relative to unequal-mass recoils even in head-on configurations. Additionally, it appears that the scaling of transverse kicks with spins is consistent with post-Newtonian theory, even though the kick is generated in the nonlinear merger interaction, where post-Newtonian theory should not apply. This suggests that a simple heuristic description might be effective in the estimation of spin-kicks.Comment: 12 pages, 10 figures.

Langdon Park Forest Patch: How three women turned their tree rescue efforts into a public-private partnership in community-based forest stewardship.

Early in the COVID-19 pandemic, community tree activists engaged in tree rescue activities in Washington, D.C.’s Langdon Park. They cleared non-native invasive vines and cataloged native tree species within the park’s 2.2-acre forest patch. Over the last 2+ years, they endeavored to share their story of forest stewardship, garnering support from district agencies and local non-profit Casey Trees. The ensuing collaboration has led to a healthier forest with greater community connection

SYSTEM AND METHOD FOR FABRICATING POLARIZATION SELECTIVE ELEMENT

A system includes a surface relief grating configured to forwardly diffract an input beam as two linearly polarized beams. The system also includes a waveplate optically coupled with the surface relief grating and configured to convert the two linearly polarized beams into two circularly polarized beams having orthogonal circular polarizations. The two circularly polarized beams having orthogonal circular polarizations interfere with one another to generate a polarization interference pattern
