Enhancing Photo Capture with Mobile AR: Augmented Reality's Influence on Farsi Speakers Digital Task Completion
(2024-07-16) Keshavarz, Ghazaleh; Walsh, Greg; Kohl, Deborah; Vincenti, Giovanni; University of Baltimore. Division of Science, Information Arts, and Technology; University of Baltimore. Doctor of Science in Information and Interaction Design
In the realm of advanced computation, Augmented Reality (AR) is becoming increasingly prevalent across various academic and industrial sectors. This study addresses the notable gap in research regarding the effects of AR mobile applications on the task performance of non-native English speakers, especially in infrequent tasks. It also examines aspects like usability, benefits, limitations, and overall effectiveness of AR. Particularly, the use of AR for photo capture is highlighted as an emerging interest. Conducted with a within-subjects design, this research involved 14 adult non-native English speakers to assess their responses and engagement with AR materials. Both qualitative and quantitative data were collected, analyzing metrics such as task duration, completion rates, post-test System Usability Scale (SUS) scores, and participant interviews. Results indicated a significant enhancement in the majority of the test results. Moreover, the study found that participants displayed overwhelmingly positive attitudes and high motivation towards using AR tools, underscoring the potential of AR technologies to improve user experience and task efficiency.

Do Foreigners Count? Internationalization of Presidential Campaigns
(SAGE, 2017-03-24) Sevin, Efe; Uzunoğlu, Sarphan; Towson University. Department of Mass Communication
The U.S. presidential elections always attract the attention of foreign audiences—who, despite not being able to vote, choose to follow the campaigns closely. For a post that is colloquially dubbed as the “Leader of the Free World,” it is not unexpected to see such an interest coming from nonvoters. Mimicking almost hosting a megaevent, the elections increase the media coverage on the United States, thus making the elections a platform to communicate with the rest of the world and to influence the reputation of the country, or its nation brand. This study postulates that the increasing adoption of social media by campaigns as well as ordinary users, increase the symbolic importance of presidential elections for foreign audiences in two ways. First, foreign audiences no longer passively follow the campaign but rather present their input to sway the American public opinion through social media campaigns. Second, foreign audiences are exposed to a variety of messages ranging from official campaigns to late-night comedy shows to local grassroots movements. The audiences both enjoy a more in-depth understanding of the elections campaigns and are exposed to alternative political views. In this study, the 2016 U.S. presidential elections are positioned as a megaevent that can influence the American nation brand. Through a comparative content and network analyses of messages disseminated over social media in the United Kingdom, Turkey, Canada, and Venezuela, the nation branding– related impacts of election campaigns are investigated.

Elementary School Physical Education Policy and High Stakes Testing: A Childhood Obesity Study
(2024-07-13) Patterson-Askew, Jarvis; Wyatt-Nichol, Heather; University of Baltimore. College of Public Affairs; University of Baltimore. Doctor of Public Administration
This two-way methods-based study explored the connection between childhood obesity rates and state health and physical education (PE) policy. Elementary school educators and administrators from the state of Maryland participated in a virtual interview, written survey, and focus group, offering their perspectives on the PE curriculum, childhood obesity, and how education legislation frames their work. Findings from this study illustrate that respondents agree that the PE curriculum will assist children in achieving recommended physical activity levels. However, respondents express PE class time is often usurped due to the prioritization of subjects represented on standardized testing. A content analysis utilizing strata from the SHAPE 2016 Shape of the Nation, and the Council of State Governments’ 2017 reports on state health and PE policy determined that states with required PE without a mandated minimum time duration and recess have the lowest average childhood obesity rates in comparison to six other policy groups: recess recommendations, states with general activity requirements, PE with a time requirement, states without activity or physical education requirements, and states with multiple policies. Additionally, selected datapoints from the 2021 National Survey of Children’s Health (NSCH) were used to examine the relationships between proxy school wellness variables and childhood obesity. A multiple regression revealed that participation in physical activity had the strongest predictive relationship with state childhood obesity outcomes over: Food Insufficiency, Frequency of Days a Family Shares a Meal, and Free or Reduce-Priced School Meals. Making interventions that focus on children’s physical activity levels a viable approach to reducing childhood obesity rates.

Estimating the climate significance of halogen-driven ozone loss in the tropical marine troposphere
(EGU, 2012-05-04) Saiz-Lopez, A.; Lamarque, J.-F.; Kinnison, D. E.; Tilmes, S.; Ordóñez, C.; Orlando, J. J.; Conley, A. J.; Plane, J. M. C.; Mahajan, A. S.; Sousa Santos, G.; Atlas, E. L.; Blake, D. R.; Sander, S. P.; Schauffler, S.; Thompson, Anne M.; Brasseur, G.
We have integrated observations of tropospheric ozone, very short-lived (VSL) halocarbons and reactive iodine and bromine species from a wide variety of tropical data sources with the global CAM-Chem chemistry-climate model and offline radiative transfer calculations to compute the contribution of halogen chemistry to ozone loss and associated radiative impact in the tropical marine troposphere. The inclusion of tropospheric halogen chemistry in CAM-Chem leads to an annually averaged depletion of around 10% (~2.5 Dobson units) of the tropical tropospheric ozone column, with largest effects in the middle to upper troposphere. This depletion contributes approximately -0.10 W m⁻² to the radiative flux at the tropical tropopause. This negative flux is of similar magnitude to the ~0.33 W m⁻² contribution of tropospheric ozone to present-day radiative balance as recently estimated from satellite observations. We find that the implementation of oceanic halogen sources and chemistry in climate models is an important component of the natural background ozone budget and we suggest that it needs to be considered when estimating both preindustrial ozone baseline levels and long term changes in tropospheric ozone.

Recent discoveries of Earth-sized planets transiting nearby M dwarfs have made it possible to characterize the atmospheres of terrestrial planets via follow-up spectroscopic observations. However, the number of such planets receiving low insolation is still small, limiting our ability to understand the diversity of the atmospheric composition and climates of temperate terrestrial planets. We report the discovery of an Earth-sized planet transiting the nearby (12 pc) inactive M3.0 dwarf Gliese 12 (TOI-6251) with an orbital period (P orb) of 12.76 days. The planet, Gliese 12 b, was initially identified as a candidate with an ambiguous P orb from TESS data. We confirmed the transit signal and P orb using ground-based photometry with MuSCAT2 and MuSCAT3, and validated the planetary nature of the signal using high-resolution images from Gemini/NIRI and Keck/NIRC2 as well as radial velocity (RV) measurements from the InfraRed Doppler instrument on the Subaru 8.2 m telescope and from CARMENES on the CAHA 3.5 m telescope. X-ray observations with XMM-Newton showed the host star is inactive, with an X-ray-to-bolometric luminosity ratio of log Lₓ / L bol ≈ -5.7. Joint analysis of the light curves and RV measurements revealed that Gliese 12 b has a radius of 0.96 ± 0.05 R⊕, a 3σ mass upper limit of 3.9 M⊕, and an equilibrium temperature of 315 ± 6 K assuming zero albedo. The transmission spectroscopy metric (TSM) value of Gliese 12 b is close to the TSM values of the TRAPPIST-1 planets, adding Gliese 12 b to the small list of potentially terrestrial, temperate planets amenable to atmospheric characterization with JWST.
