Evaluation of Participation and Environments for Individuals with Disabilities: An Evidence-Based Practice Project Bailey

This Evidence-Based Practice (EBP) project considered the following question: What measures are available to evaluate participation and environmental supports and barriers for individuals with disabilities and what are their psychometric properties

Adaptive divergence in shoot gravitropism creates hybrid sterility in an Australian wildflower.

Natural selection is responsible for much of the diversity we see in nature. Just as it drives the evolution of new traits, it can also lead to new species. However, it is unclear whether natural selection conferring adaptation to local environments can drive speciation through the evolution of hybrid sterility between populations. Here, we show that adaptive divergence in shoot gravitropism, the ability of a plant's shoot to bend upwards in response to the downward pull of gravity, contributes to the evolution of hybrid sterility in an Australian wildflower, Senecio lautus We find that shoot gravitropism has evolved multiple times in association with plant height between adjacent populations inhabiting contrasting environments, suggesting that these traits have evolved by natural selection. We directly tested this prediction using a hybrid population subjected to eight rounds of recombination and three rounds of selection in the field. Our experiments revealed that shoot gravitropism responds to natural selection in the expected direction of the locally adapted population. Using the advanced hybrid population, we discovered that individuals with extreme differences in gravitropism had more sterile crosses than individuals with similar gravitropic responses, which were largely fertile, indicating that this adaptive trait is genetically correlated with hybrid sterility. Our results suggest that natural selection can drive the evolution of locally adaptive traits that also create hybrid sterility, thus revealing an evolutionary connection between local adaptation and the origin of new species

Practical Digital Curation Skills for Archivists in the 21st Century

The University of Maryland's Digital Curation Innovation Center (DCIC) in the College of Information Studies promotes research and education in digital curation and fosters interdisciplinary partnerships using Big Records and archival analytics through public, industry, and government partnerships. In this session, technologists, archivists, and students from the DCIC will provide case studies involving archival records in a digital environment that focus on redlining in urban neighborhoods, the Japanese American experience in World War II internment camps, and navigating Holocaust-era digital data

Development of advanced material modelling for metal additive manufacturing

This thesis was submitted for the award of Doctor of Philosophy and was awarded by Brunel University LondonAdditive manufacturing (AM) is becoming an increasingly popular manufacturing process due to its design freedoms and material efficiency. However, the use of AM in industry is limited by the reliability of the deposited parts. Process-microstructure-property relationships are of paramount importance to increasing understanding and consistency within additive processes. Within this work, thermal and microstructure modelling methods are investigated to develop an efficient approach to the simulation of solidification microstructure. Finite element thermal models are considered as well as the implementation of analytical solutions. Cellular automata methods are used to simulate grain growth, 2D models are implemented for computational efficiency. The established approach is applied to three case studies within this work. The first is the application to laser scans on a bare nickel superalloy substrate, followed by the application to direct energy deposition techniques. Within the second study the capability of the modelling approach to capture changes in microstructure as a result of a change in process parameters is investigated. Finally, the modelling approach is applied to functionally graded materials through in situ changes in process parameters.National Structural Integrity Research Centre (NSIRC

Promoting Dual Language Immersion

Advanced Spanish students at BSU (SP305, SP404, SP340) collaborated with elementary schools at two community school districts to promote their dual language immersion (DLI) programs. BSU students explored the state of bilingualism in the U.S. and the benefits of programs such as DLI that enable students to develop proficiency in both Spanish and English, strengthen academic learning and achievement, and cultivate intercultural sensitivity.Files associated with this immersive learning project include the brochures "Why Bilingual Education Is Right For Your Child" and "Por Qué La Educación Bilingüe Mejore El Aprendizaje De Su Hijo" to promote the program within Muncie Community Schools
