Evaluation Of Pierce’S Disease-Resistant Grapevine Cultivars In Upstate South Carolina, Annie Bruno

All Theses

Interest in wine grape production is increasing in South Carolina, but Pierce’s Disease (PD) caused by the xylem-limited bacteria Xylella fastidiosa (Xf) is a major limiting factor. Xf is spread by sap-sucking insect vectors in the Cicadellidae family such as sharpshooters. In the United States, Xf has become endemic to the southeast as global temperatures rise, causing winter temperatures to increase, which allows the bacteria to survive year-round. However, PD-resistant grapevine hybrid cultivars have become available through breeding V. vinifera genes with native American Vitis species that are resistant to Xf. In this study, the PD-resistant grapevine …

Older adults participate in different types of activities and do so in varying frequencies. In this study, we utilised latent class analysis to identify underlying patterns of activity participation among the SLP respondents. We found three patterns: (i) generally active (i.e., socially, physically, and digitally active), (ii) physically and digitally active, and (iii) digitally active. Furthermore, we found that respondents who were more broadly active were more likely to experience higher levels of life satisfaction than those who were only digitally active. These respondents tended to be from higher socioeconomic backgrounds, report having better health, or had more close social …

The World Bank's New Approach To Human Capital Model And Education, Ozlem Kucuk, Cihan Cobanoglu

University of South Florida (USF) M3 Publishing

The human capital approach, introduced in 1960, has been used by economists to establish connections between education, skills, and personal income. It resulted in a redistribution of public expenditure by viewing education not only as a cost but also as an economic input, a way to increase revenue in the medium and long term. Human capital theory highlights the crucial role of education in the economy. With the rise of the knowledge society, scientists have debated the potential end of poverty, inequality, and social exclusion. They envisioned a new knowledge economy and a more egalitarian society.

Soybean Cyst Nematode (Heterodera Glycines Ichinohe) Virulence Assay Against Resistance Sources In Nebraska, Pratibha Karki

Department of Plant Pathology: Dissertations, Theses, and Student Research

Soybean cyst nematode (SCN, Heterodera glycines Ichinohe), one of the major yield-limiting pathogens of soybean, is currently found in 60 counties of Nebraska that produce more than 90% of the state’s soybean. Often, yield loss occurs without any above-ground symptoms, which makes it difficult to manage. The primary management option is the use of SCN-resistant varieties. Several soybean plant introductions serve as resistance sources against SCN. Unfortunately, the single source, PI 88788, is used in approximately 90% of resistant varieties and its prolonged use has increased the virulence status of SCN in the U.S. A study was conducted to assess …

Andrew Nelson, Nicholas J. Goode, Ryan P. Lis, Sungwon Chae, Satoshi Mizuguchi, Marten Baur, Kevin F. Breuel, Marco Duca, John P. Wagle, Andy C. Fry, Michael H. Stone

Kinesiology

Featured Application: Research on the endocrine changes from AEL training is limited, especially for long-term effects. This study suggests that combining AEL with CS might offer similar or slightly better results compared to traditional training. However, the practical challenges, such as increased training monotony and strain, may outweigh the minimal benefits. The extra cost, time, and effort required for AEL, especially in large team settings, might not be justified. Additionally, individual differences in optimal loading prescriptions could complicate its use, making traditional methods more efficient. This study investigated the endocrine responses to accentuated eccentric loading (AEL) paired with cluster sets …

Bad Plants, Heather I. Sullivan

Modern Languages and Literatures Faculty Research

“Bad plants” represent the seemingly unexpected and startling forms of plant power overlooked by many modern, industrialized societies that treat vegetal beings as mere resources instead of animate, world-shaping forces. Since science fiction and fairy tales often explore more openly animistic visions of non-human life, such texts provide ample possibilities for reconsideration by critical plant studies of our human-plant relations both cultural and ecological. For example, both Jack McDevitt’s 2001 science fiction novel, Deepsix, and Ludwig Tieck’s 1799 fairy tale, “Faithful Eckart and Tannhäuser”, feature “bad plants” that bring human beings violently back into the plant cycles they assume they …
