Asesing Short term Study Abroad Impact on Host Communities: The case of Ghana

The numerous surveys and publications on short term study abroad programs have neglected, or largely ignored, how host communities are impacted by these programs. Questions such as what sort of interactions the students have with local communities in host countries and how these communities view and relate to the students have almost no published assessment to inform STA practitioners and international program that’s develop STAs. Organizations such as the Institute for International Education (IIE), School of International Training (SIT), and many others have little or no data on the effects of study abroad programs on local communities. The Forum on Education Abroad Standards of Good Practice for Education Abroad (2008, 19) only cautions students and the organizations sending the students to “respect the cultures and values of the countries in which it operates.” This study seeks to shed light on how these programs influence, impact, and effect change on host communities and how those in the communities view the STAs. Two communities, Tse Addo and UG, were the survey sites. Findings of the study reveal the need for more collaboration and effort be placed in developing mutually beneficial, targeted, and meaningful experiential learning not only for he students, but also where that learning takes place

Data and scripts from: Measuring the ferromagnetic resonance cone angle via static dipolar fields using diamond spins

[dataset] Cornell University Library eCommons Repository. https://doi.org/10.7298/w5q0-1g13These files contain data supporting all results reported in McCullian et al., Measuring the ferromagnetic resonance cone angle via static dipolar fields using diamond spins. In McCullian et al. we demonstrate quantitative measurement of the ferromagnetic resonance (FMR) precession cone angle of a micro-scale sample of vanadium tetracyanoethylene (V[TCNE]$_{x\sim 2}$) using diamond spins. V[TCNE]$_{x\sim 2}$ is a low-damping, low-magnetization ferrimagnet with potential for scalable spintronics applications. Our study is motivated by the persistent need for quantitative metrology to accurately characterize magnetic dynamics and relaxation. Recently, diamond spins have emerged as sensitive probes of static and dynamic magnetic signals. Unlike analog sensors that require additional calibration, diamond spins respond to magnetic fields via a frequency shift that can be compared with frequency standards. We use a spin echo-based approach to measure the precession-induced change to the static stray dipolar field of a pair of V[TCNE]$_{x\sim 2}$ discs under FMR excitation. Using these stray dipolar field measurements and micromagnetic simulations, we extract the precession cone angle. Additionally, we quantitatively measure the microwave field amplitude using the same diamond spins, thus forming a quantitative link between drive and response. We find that our V[TCNE]$_{x\sim 2}$ sample can be driven to a cone angle of at least 6$^{\circ}$ with a microwave field amplitude of only 0.53 G. This work highlights the power of diamond spins for local, quantitative magnetic characterization.The design and fabrication of our device, all the measurements, and all data analysis were supported by the Department of Energy Office of Science, Basic Energy Sciences Quantum Information Sciences program (DE-SC0019250).

Allegories of Format: A Media History of Gottfried Keller's Unlikely Oeuvre

Allegories of Format examines the significance of format to the literary oeuvre of the nineteenth-century Swiss author, Gottfried Keller (1819–1890), best known for his 1855 novel, Green Henry (Der grüne Heinrich). Malika Maskarinec understands format as the organization of a media object's relationship to a world of objects and persons; format orders a text's contents or, in the case of literature, what it represents. Maskarinec focuses on three formats of growing prominence in nineteenth-century media culture: the collected-works edition, the document, and the periodical. The analysis demonstrates that different fictional worlds, characters, and plots in Keller's literary output allegorize the problems that specific print and paper formats pose to literary ideals of literature as an art form and to ideals of creative authorship. As Allegories of Format shows, attending to format allows for false antitheses inherited from the nineteenth century to be dismantled—between high and trivial literature, between the singular artwork and mass media products, and between creative literary works and the supposedly uncreative writing practices of office work

Meta-Analysis of Coronary Bypass Graft Patency Assessment With Invasive vs Computed Tomographic Angiography

BACKGROUND: Computed tomography (CT) coronary angiography has emerged as a non-invasive alternative for evaluating graft patency after coronary artery bypass grafting (CABG), but there is ongoing debate regarding its diagnostic performance compared to invasive coronary angiography, particularly for arterial and composite grafts. METHODS: MEDLINE, Embase, and Cochrane databases were searched to identify studies comparing CT coronary angiography to invasive coronary angiography for detection of graft occlusion in post-CABG patients. Outcomes included sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy. Meta-regression explored key modifiers. Pooled estimates were calculated using random-effects models, with heterogeneity measured via I2. RESULTS: Fifty studies met inclusion criteria, including 3,449 patients (25% women). CT coronary angiography sensitivity for graft occlusion was 0.96 (I2 = 48%), specificity was 0.97 (I2 = 46%), positive predictive value was 0.94 (I2 = 62%), negative predictive value was 0.98 (I2 = 41%) and overall diagnostic accuracy was 0.97 (I2 = 58%). The pooled incidence rate of graft occlusion across 7,506 included grafts was 0.08 per graft-year (PGY) (95% CI: 0.06-0.10) using a random-effects model, and 0.07 PGY (95% CI: 0.07-0.08). At meta-regression, study year, sample size, β-blocker use, number of slices, and time since surgery, but not type and configuration of CABG grafts, were significantly associated with CT coronary angiography sensitivity. CONCLUSIONS: CT coronary angiography detects coronary artery bypass graft occlusion with a high degree of sensitivity and specificity independently of graft type and configuration and can be used for imaging of every type of CABG graft.2026-07-0

Out of Sight, Out of Budget: the Invisibility Crisis in U.S. Infrastructure Maintenance

This thesis investigates why infrastructure maintenance in the United States remains chronically underfunded despite its economic and safety benefits. Focusing on roadway systems, it argues that the root cause lies in the low political and public visibility of maintenance activities. Through a literature review and in-depth interviews with transportation officials across state and local agencies, the study finds that maintenance is often deprioritized in budgets because it lacks the immediate, visible benefits politicians can leverage for credit-claiming. Case studies from six jurisdictions reveal how maintenance officials navigate funding constraints, visibility challenges, and intergovernmental dynamics. The research also explores the different strategies that can help elevate the profile of maintenance, as well as the implications of elevating visibility. This thesis contributes to the broader understanding of infrastructure policy and calls for changes to enhance long-term infrastructure asset stewardship in the U.S

Asian Enclaves under Pressure: Social and Environmental Justice in Flushing and Boston's Chinatown

Asian American communities experience intersecting challenges of social and environmental injustices that threaten residents' healthy long-term standard of living and even lead to displacement. This research case investigates and examines the injustices faced by two Asian enclaves on the eastern coast of the United States: Flushing in New York City and Chinatown in Boston. This research takes a comparative case study approach to explore the impact of environmental pollution, lack of infrastructure, and development of upscale housing on these marginalized communities. This paper highlights how systemic neglect and unequal development disproportionately affect the lives of low-income Asian immigrants and Asian Americans and how community organizing and inclusive urban planning can resist these unjust conditions and aid in transformative change. This paper contributes to environmental and social justice in ethnic enclaves by proposing strategies for equitable and inclusive development

How advances in DNA sequencing and bioinformatics have revolutionized grape breeding

This article is based on a conversation (December 2023) in which Dr. Bruce Reisch reflected on how the introduction of molecular breeding tools evolved during his 40-year career as professor of grape genetics and breeding at Cornell University (1980-2023).A generation of grape breeders has retired over the past three years. Programs at UC Davis, Cornell, the USDA-ARS at Parlier, California, the University of Minnesota, and a new program at the USDA-ARS unit in Kearneysville, West Virginia have hired a new crop of grape breeders and geneticists. These newly-hired breeders now have access to a host of tools, including a detailed map of the 19 chromosomes in the grapevine genome, numerous DNA markers predicting important traits such as disease resistance, and the ability to use marker-assisted selection in their breeding programs. None of this existed when their predecessors started their careers in the ‘80s or ‘90s. A generation ago, almost nothing was known about grapevine genetics. Crosses were made by choosing parents with complementary traits (phenotypes), and selecting progeny that expressed the best combination of traits observed in the field. A dramatic drop in the cost of sequencing DNA has driven a revolution in grape breeding. Grape breeders, for the first time, have access to detailed genetic information to guide their efforts. They are no longer flying blind.VitisGen2: Application of Next Generation Technologies to Accelerate Grapevine Cultivar Development, USDA Specialty Crops Research Initiative, Award No. 2017- 51181-26829 Cornell Cooperative Extensio
