Hamilton, Hubbard Use Inbre Grant To Bring New Instruments To Ouachita Chemistry Program, Kaitlyn Stoddard, Ouachita News Bureau

Press Releases

Ouachita Baptist University chemistry instructors Dr. Sharon Hamilton and Dr. Sara Hubbard were awarded a $14,135 small instrument grant by the Arkansas IdeA Network of Biomedical Research Excellence (INBRE), which they used to purchase a spectrophotometer and a fluorometer for use by students in Ouachita’s Department of Chemistry. The grant was made possible by the National Institute of General Medical Sciences in the National Institutes of Health.

Hubbard, associate professor and Nell I. Mondy Chair of Chemistry, and Hamilton, associate professor of chemistry, were notified of their award in January. They collaborated with Dr. Christen Pruett and Dr. Ruth Plymale, …

Investigating Hops Production In Arkansas To Support Specialty Crop Growth, James Oliver Mcclellan

Graduate Theses and Dissertations

The hop plant (Humulus lupulus L.) is a perennial, climbing species within the Cannabaceae family that produces cones used for brewing. Hops are grown worldwide. In the United States most hops production occurs in the Pacific Northwest, but growth in the craft beer industry is driving efforts for hops production in other U.S. regions. Recommendations on hops cultivar suitability, fertility, and management are needed for the U.S. mid-south region. Objectives of this research on Arkansas-grown hops were to 1) assess the impact of cultivar and fertility rate on plant and cone attributes of six cultivars of Arkansas-grown hops and 2) …

Development Of The Cooperative Adoption Factors Instrument To Measure Factors Associated With Instructional Practice In The Context Of Institutional Change, John P. Ziker, Brittnee Earl, Karl Mertens, Susan E. Shadle

Anthropology Faculty Publications and Presentations

Background: Many institutional and departmentally focused change efforts have sought to improve teaching in STEM through the promotion of evidence-based instructional practices (EBIPs). Even with these efforts, EBIPs have not become the predominant mode of teaching in many STEM departments. To better understand institutional change efforts and the barriers to EBIP implementation, we developed the Cooperative Adoption Factors Instrument (CAFI) to probe faculty member characteristics beyond demographic attributes at the individual level. The CAFI probes multiple constructs related to institutional change including perceptions of the degree of mutual advantage of taking an action (strategic complements), trust and interconnectedness among colleagues …

Evaluating Cremation In Umm An-Nar Period Mortuary Practices Using Laser-Induced Breakdown Spectroscopy (Libs), Malena Butler

Anthropology Undergraduate Senior Theses

Chemical changes in bone composition that occur during the process of cremation have begun to be explored alongside corresponding macroscopic changes to bone color using a variety of analytical instrumentation. This research employed a lesser-utilized method, Laser-Induced Breakdown Spectroscopy (LIBS), alongside Munsell Color Charts to assess elemental changes that may occur in archaeological bone at varying cremation temperatures. It was hypothesized that differences in color would be indicative of different chemical compositions present in bone, despite previous evidence for at least some diagenetic change. Distal humeri from Umm an-Nar (2700-2000 BCE) period tombs Unar 1 (n=31) and Unar 2 (n=28) …

Strategic Consideration And Recommendation On Development Of Chemistry In China, Yanlin Cheng, Shuxian Wu, Qing Dai, Chunying Chen, Yuliang Zhao

Bulletin of Chinese Academy of Sciences (Chinese Version)

Chemistry, as a central science linking all the other sciences, has played an influential role in promoting the development of the whole scientific and technological field and the prosperity of economy and society. Developed countries strongly support the development of chemistry and effectively promote the level of chemical research and chemical industry. Since the founding of the People's Republic of China, chemical research has been supported among the field of natural sciences, and its current level is at the forefront of the world. However, there are still problems in the field of chemistry research in China, such as insufficient major …

P3k14c, A Synthetic Global Database Of Archaeological Radiocarbon Dates, Erick Robinson

Anthropology Faculty Publications and Presentations

Archaeologists increasingly use large radiocarbon databases to model prehistoric human demography (also termed paleo-demography). Numerous independent projects, funded over the past decade, have assembled such databases from multiple regions of the world. These data provide unprecedented potential for comparative research on human population ecology and the evolution of social-ecological systems across the Earth. However, these databases have been developed using different sample selection criteria, which has resulted in interoperability issues for global-scale, comparative paleo-demographic research and integration with paleoclimate and paleoenvironmental data. We present a synthetic, global-scale archaeological radiocarbon database composed of 180,070 radiocarbon dates that have been cleaned according …
