Breaking Down the Codes: A Study of the Nonverbal Emblems and Regulators Used in International B-Boy Competitions

This study explored the use of nonverbal emblems and regulators in international b-boy competitions. Using semiotics, a lexicon of the emblems and regulators was recorded. Then the dimensions from a theory of semantics of dance were applied to understand how b-boy crews (dance teams) from around the world use gesture to communicate with the audience, judges, and other crews. The study analyzed how culture influences the use of emblems and regulators in the intercultural exchange that occurs during the international b-boy competitions, such as Battle of the Year (BOTY) and R16 World Series. Four videos from the 2013 and 2014 BOTY and 2015 R16 were analyzed. The study concluded that cultural dimensions such as collectivism and indulgence influences emblem selection, intensity, and frequency. These nonverbal elements exhibit an overall impact on the battle and the determination of the winner. The paper upon which this poster was based was written for the Senior Seminar course in Communication Arts. The paper was competitively selected for presentation at the Northwest Communication Association Conference in April 2016

Genetic Modification, Factory Farms, and ALF: A Focus Group Study of the Netflix Original Film Okja

Okja is a fictional Netflix original film that was released in 2017. Okja features a “super pig” that is owned by the large, agricultural company Mirando Corporation. Okja is raised by a young girl, Mija, and her grandfather in the South Korean mountains. The film climaxes when Mija and the Animal Liberation Front (ALF) narrowly save Okja and a smuggled piglet from the slaughter process. The purpose of this study was to understand how college students responded to the film. The viewers of this film included students who were majoring in a field within the agricultural college (COA) at Texas Tech University as well as students who were majoring in a field outside of agriculture (NCOA). Emergent themes from this focus group study identified the film as overdramatized and that the film misrepresented food production. Previous knowledge and experiences impacted how viewers perceived the film with COA students indicating that Okja was portrayed more like a pet than as a food animal. Both COA and NCOA students indicated that their food purchasing decisions would not be affected by viewing the film. Findings suggested that entertainment films may not be an effective method for changing public opinion of agriculture and food production. Transparency in agriculture through real-life and real-time activities in a documentary style may serve a greater role in improving public opinion of food and agricultural production practices and industries.Findings from this study serve as an indicator of the role entertainment films play in swaying public opinion of food and agriculture

Calculation of Lifecycle Greenhouse Gas Emissions for the Renewable Fuel Standard

The Energy Independence and Security Act of 2007 (EISA) significantly expanded the renewable fuel standard (RFS) established in the Energy Policy Act of 2005. EISA requires an increasing amount of the 36 billion gallons of renewable fuel by 2022 mandate be met with "advanced biofuels." This report defines the classification "biofuels," discusses the ongoing debate regarding several aspects of biofuels endeavors, and discusses related legislative efforts on climate change policy and low-carbon fuel standards

Vacuum ultraviolet photoabsorption spectra of nitrile ices for their identification on Pluto

Icy bodies, such as Pluto, are known to harbor simple and complex molecules. The recent New Horizons flyby of Pluto has revealed a complex surface composed of bright and dark ice surfaces, indicating a rich chemistry based on nitrogen (N2), methane (CH4), and carbon monoxide (CO). Nitrile (CN) containing molecules such as acetonitrile (CH3CN), propionitrile (CH3CH2CN), butyronitrile (CH3CH2CH2CN), and isobutyronitrile ((CH3)2CHCN) are some of the nitrile molecules that are known to be synthesized by radiative processing of such simple ices. Through the provision of a spectral atlas for such compounds we propose that such nitriles may be identified from the ALICE payload on board New Horizons</i

Photometry of Kuiper belt object (486958) Arrokoth from New Horizons LORRI

On January 1st 2019, the New Horizons spacecraft flew by the classical Kuiper belt object (486958) Arrokoth (provisionally designated 2014 MU69), possibly the most primitive object ever explored by a spacecraft. The I/F of Arrokoth is analyzed and fit with a photometric function that is a linear combination of the Lommel-Seeliger (lunar) and Lambert photometric functions. Arrokoth has a geometric albedo of p_v = 0.21_(−0.04)^(+0.05) at a wavelength of 550 nm and ≈0.24 at 610 nm. Arrokoth's geometric albedo is greater than the median but consistent with a distribution of cold classical Kuiper belt objects whose geometric albedos were determined by fitting a thermal model to radiometric observations. Thus, Arrokoth's geometric albedo adds to the orbital and spectral evidence that it is a cold classical Kuiper belt object. Maps of the normal reflectance and hemispherical albedo of Arrokoth are presented. The normal reflectance of Arrokoth's surface varies with location, ranging from ≈0.10–0.40 at 610 nm with an approximately Gaussian distribution. Both Arrokoth's extrema dark and extrema bright surfaces are correlated to topographic depressions. Arrokoth has a bilobate shape and the two lobes have similar normal reflectance distributions: both are approximately Gaussian, peak at ≈0.25 at 610 nm, and range from ≈0.10–0.40, which is consistent with co-formation and co-evolution of the two lobes. The hemispherical albedo of Arrokoth varies substantially with both incidence angle and location, the average hemispherical albedo at 610 nm is 0.063 ± 0.015. The Bond albedo of Arrokoth at 610 nm is 0.062 ± 0.015

Studying the [OIII]λ\lambda5007A emission-line width in a sample of ∼\sim80 local active galaxies: A surrogate for σ⋆\sigma_{\star}?

For a sample of $\sim$80 local ($0.02 \leq z \leq 0.1$) Seyfert-1 galaxies with high-quality long-slit Keck spectra and spatially-resolved stellar-velocity dispersion ($\sigma_{\star}$) measurements, we study the profile of the [OIII]$\lambda$5007A emission line to test the validity of using its width as a surrogate for $\sigma_{\star}$. Such an approach has often been used in the literature, since it is difficult to measure $\sigma_{\star}$ for type-1 active galactic nuclei (AGNs) due to the AGN continuum outshining the stellar-absorption lines. Fitting the [OIII] line with a single Gaussian or Gauss-Hermite polynomials overestimates $\sigma_{\star}$ by 50-100%. When line asymmetries from non-gravitational gas motion are excluded in a double Gaussian fit, the average ratio between the core [OIII] width ($\sigma_{\rm {[OIII],D}}$) and $\sigma_{\star}$ is $\sim$1, but with individual data points off by up to a factor of two. The resulting black-hole-mass-$\sigma_{\rm {[OIII],D}}$ relation scatters around that of quiescent galaxies and reverberation-mapped AGNs. However, a direct comparison between $\sigma_{\star}$ and $\sigma_{\rm {[OIII],D}}$ shows no close correlation, only that both quantities have the same range, average and standard deviation, probably because they feel the same gravitational potential. The large scatter is likely due to the fact that line profiles are a luminosity-weighted average, dependent on the light distribution and underlying kinematic field. Within the range probed by our sample (80-260 km s$^{-1}$), our results strongly caution against the use of [OIII] width as a surrogate for $\sigma_{\star}$ on an individual basis. Even though our sample consists of radio-quiet AGNs, FIRST radio-detected objects have, on average, a $\sim$10% larger [OIII] core width.Comment: 15 pages, 10 figures, 6 tables.

Associations of social determinants of health and childhood obesity. A cross-sectional analysis of the 2021 National Survey of Children’s Health

Background: Childhood obesity is a growing health problem in the United States, with those affected having an increased likelihood of developing chronic diseases at a younger age. Social determinants of health (SDOH) are known to influence overall health. Children with low socioeconomic status (SES) have been shown to be overweight and have poor health outcomes. Therefore, our primary objective was to use the National Survey of Children’s Health (NSCH) 2021 data to determine current associations between childhood obesity and social determinants of health (SDOH).Methods: We conducted a cross-sectional analysis of 2021 NSCH to extract data from questions related to the SDOH domains. We extracted sociodemographic variables to use as controls and constructed bivariate and multivariable logistic regression models to determine associations, via odds ratios, between SDOH and child obesity.Results: Within the binary regression models, we found that children identified as having obesity were more likely than non-obese children to experience SDOH in all domains. After controlling for race/ethnicity, household income (%FPL), parental education, and child sex, children identified as having obesity were significantly more likely to experience food insecurity when compared to non-obese children (AOR = 1.39; 95% CI: 1.13-1.17).Conclusion: Our study found that the food insecurity domain of SDOH was significantly associated with childhood obesity. Improving policies for programs such as SNAP as well as addressing lack of access to nutritious foods, especially within food deserts, may help alleviate some food insecurity. Improving access to adequate amounts of nutritious foods is critical in addressing childhood obesity and thus, decreasing risk of chronic disease and poor long-term health outcomes
