The Past, Present, And Future Of Water Conflict And International Security, David K. Kreamer

Journal of Contemporary Water Research and Education

Water stress and scarcity has affected, and will continue to affect, the stability of communities. An overview of global water security challenges indicates profound difficulties and potential flashpoints. There are many examples of struggles in supplying clean water throughout the world, and how water has been both a strategic tool and object of conflict in the past. Water has been an instrument of ethnic and religious conflict, and has recently been used in regional and local clashes. Transboundary water disputes are also potentially dangerous in several regions of the world and stresses from climate change and variability increase the uncertainty …

Transcript Abundance Responses Of Resistance Pathways Of Arabidopsis Thaliana To Deoxynivalenol, Jiazheng Yuan, Michelle M. Zhu, Khalid Meksem, Matt Geisler, Patrick Hart Dr, David A. Lightfoot

Articles

Mycotoxin deoxynivalenol (DON), produced by Gibberella zeae (Schwein.) Petch (teleomorph of Fusarium graminearum Schwabe) was known to be both a virulence factor in the pathogenesis of Triticum aestivum L. (wheat) and an inhibitor of Arabidopsis thaliana L. seed germination. Fusarium graminearum causes both Gibberella ear rot in maize (Zea mays L.) and Fusarium head blight (FHB) in wheat and barley. Arabidopsis thaliana was also a host for the related root rot pathogen F. virguliforme Aoki. A. thaliana seedling growth was reduced by the pathogen in a proportional response to increasing spore concentrations. Here, the changes in transcript abundances corresponding to …

Homo-Dimerization And Ligand Binding By The Leucine-Rich Repeat Domain At Rhg1/Rfs2 Underlying Resistance To Two Soybean Pathogens, Ahmad Walid Afzali, Ali Srour, Abhishek Goil, Sheeja Vasudaven, Tianyun Liu, Ram Samudrala, Navneet Dogra, Punit Kohli, Ayan Malakar, David A. Lightfoot

Articles

Background: The protein encoded by GmRLK18-1 (Glyma_18_02680 on chromosome 18) was a receptor like kinase (RLK) encoded within the soybean (Glycine max L. Merr.) Rhg1/Rfs2 locus. The locus underlies resistance to the soybean cyst nematode (SCN) Heterodera glycines (I.) and causal agent of sudden death syndrome (SDS) Fusarium virguliforme (Aoki). Previously the leucine rich repeat (LRR) domain was expressed in Escherichia coli.

Results: The aims here were to evaluate the LRRs ability to; homo-dimerize; bind larger proteins; and bind to small peptides. Western analysis suggested homo-dimers could form after protein extraction from roots. The purified LRR domain, from …

Loss Of Mef2d Expression Inhibits Differentiation And Contributes To Oncogenesis In Rhabdomyosarcoma Cells., Meiling Zhang, Jamie Truscott, Judith Davie

Articles

BACKGROUND: Rhabdomyosarcoma (RMS) is a highly malignant pediatric cancer that is the most common form of soft tissue tumors in children. RMS cells have many features of skeletal muscle cells, yet do not differentiate. Thus, our studies have focused on the defects present in these cells that block myogenesis.

METHODS: Protein and RNA analysis identified the loss of MEF2D in RMS cells. MEF2D was expressed in RD and RH30 cells by transient transfection and selection of stable cell lines, respectively, to demonstrate the rescue of muscle differentiation observed. A combination of techniques such as proliferation assays, scratch assays and soft …

Exploring Linkages Between Consumer Food Co-Operatives And Domestic Fair Trade In The United States, Leslie Duram

Publications

Consumer Food Co-operatives (co-ops) have provided consumers an alternative to corporate supermarkets and big-box stores since the 1960s. Producers seeking broader marketing opportunities often turn to co-ops. This study examines how, within Alternative Food Networks (AFNs), co-ops play a role in the emergence of the Domestic Fair Trade movement in the US. The Domestic Fair Trade (DFT) movement is based on the idea that family farms and small- to mid-sized farms in the global north are facing many of the same pressures as producers in the global south. The Domestic Fair Trade Association (DFTA) in the United States is the …

Additional Quantitative Trait Loci And Candidate Genes For Seed Isoflavone Content In Soybean, M Akond, Bazelle Richard, Bobby Ragin, Harmin Herrera, Umerah Kaodi, Cevdet Akbay, Stella K. Kantartzi, Victor Njiti, Abdelali Barakat, Khalid Meksem, David A. Lightfoot, My Abdelmajid Kassem

Articles

Seed isoflavone content of soybean (Glycine max L. Merr.) is a trait of moderate heritablity and an ideal target for marker selection. To date over 20 QTL have been identified underlying this trait among seven populations. The objectives of this study were to identify additional QTL and candidate genes controlling isoflavone content in a set of recombinant inbred line (RIL) populations of soybean grown in two different seasons. Variations of isoflavones namely daidzein, glycitein and genistein contents over two growing seasons and locations suggests that isoflavones are influenced by both genes and environments. Six QTL were identified on five …

Sustainability Initiatives In The Workplace And Employee Productivity, Megan R. Nollman

Research Papers

Sustainability in the workplace has the potential to affect many aspects of an organization, including employee productivity. Sustainable designers, such as LEED (Leadership in Energy and Environmental Design) professionals, claim that sustainability has numerous positive impacts in the workplace. These impacts include fewer employee sick days, increased building occupant satisfaction, and increased employee productivity. Researchers that have studied this claim have found that in many cases, sustainable initiatives and buildings have had a slight to profound positive effects on occupant satisfaction, attendance, and productivity. Lower levels of satisfaction for lighting and acoustics are common, though, because many sustainable workplaces use …

Long Run Employment And Income Growth: A By Sector Analysis, Christopher Hooks

Research Papers

Given today’s economic conditions it is becoming more essential to gain a better understanding of long run economic development in the US. This paper seeks to find economic sectors that show a significant impact on employment and income growth. This was done by estimating the elasticities for individual sectors (Manufacturing, Trade, Information, Business Services and Finance, Health and Education, and Other) and using a growth accounting approach to determine the contributions of labor for each. Over the sample period years (2001-11) it was found that business services and finance had the highest contribution to labor growth with an average annual …

Multiplex Networks And Interest Group Influence Reputation: An Exponential Random Graph Model, Michael T. Heaney

Working Papers

Interest groups struggle to build reputations as influential actors in the policy process and to discern the influence exercised by others. This study conceptualizes influence reputation as a relational variable that varies locally throughout a network. Drawing upon interviews with 168 interest group representatives in the United States health policy domain, this research examines the effects of multiplex networks of communication, coalitions, and issues on influence reputation. Using an exponential random graph model (ERGM), the analysis demonstrates that multiple roles of confidant, collaborator, and issue advocate affect how group representatives understand the influence of those with whom they are tied, …

Four Events Of Host Switching In Aspidoderidae (Nematoda) Involve Convergent Lineages Of Mammals, F Agustin Jimenez-Ruiz, Scott L Gardner, Graciela Navone, Guillermo Ortí

Publications

The Great American Interchange resulted in the mixing of faunistic groups with different origins and evolutionary trajectories that underwent rapid diversification in North and South America. As a result, groups of animals of recent arrival converged into similar habits and formed ecological guilds with some of the endemics. We present a reconstruction of the evolutionary events in Aspidoderidae, a family of nematodes that infect mammals that are part of this interchange, i.e., dasypodids, opossums, and sigmodontine, geomyid, and hystricognath rodents. By treating hosts as discrete states of character and using parsimony and Bayesian inferences to optimize these traits into the …

Vitamin D Deficiency And Cultural Influences Among Muslim Women In Southern Illinois, Durar Kassim Shakir

Theses

This study is an analysis of the cultural influences that affect the prevalence of vitamin D deficiency among Muslim women from sun-rich countries, who now reside in Southern Illinois. Previous studies examine the prevalence of vitamin D deficiency among this population, while neglecting to examine the extent of cultural influences which can affect the likelihood of having this disorder. Low serum levels of 25(OH)D can occur when there are low levels of vitamin D intake, and when exposure to sunlight is limited. Muslim women are more prone to vitamin D deficiency due to traditional attire, regardless of migration. Upon surveying …

Activity Of The Beta-Cyanoalanine Synthase Pathway Is Associated With The Response To Abiotic Stress By Arabidopsis Thaliana., Marylou Machingura

Dissertations

Cyanide is produced throughout a plant's life cycle alongside the hormone ethylene by oxidation of 1-aminocyclopropane-1-carboxylic acid. Production increases during certain developmental stages such as seed germination, seedling elongation, fruit ripening and senescence. Abiotic stresses increase ethylene production giving rise to `stress cyanide'. Cyanide also comes from metabolism of cyanogenic compounds. Cyanide is however, a toxic chemical which readily binds to metallo-enzymes inhibiting primary metabolic processes. Plants have mechanisms to maintain cyanide homeostasis such as the β-cyanoalanine pathway whereby cysteine reacts with cyanide forming β--cyanoalanine, mediated by β-cyanoalanine synthase and cysteine synthase. A dual nitrilase 4 enzyme then converts the …

Modeling The Distribution Of Meadows In Arid And Semi-Arid Patagonia, Argentina: Assessing Current Distribution And Predicting Response To Climate Change, Ramiro Daniel Crego

Theses

Meadows are critical in arid and semi-arid Argentinean Patagonia because of their importance for regional biodiversity. Despite this, little information on the spatial distribution of meadows is available and no analysis of the potential effect of climate change on meadows has been performed, which hampers conservation planning. In this study, I modeled the spatial distribution of meadows and investigated how climate change may affect the current distribution of meadows in arid and semiarid Patagonia by 2050. In addition, I investigated conservation status and areas of desertification vulnerability of those areas predicted to contain meadows. I used high-resolution imagery available in …
