Prebiotic Galactooligosaccharides Reduce Adherence Of Enteropathogenic Escherichia Coli To Tissue Culture Cells, Kari Schoaf, George L. Mulvey, Glen D. Armstrong, Robert W. Hutkins

Department of Food Science and Technology: Faculty Publications

Prebiotic oligosaccharides are thought to provide beneficial effects in the gastrointestinal tract of humans and animals by stimulating growth of selected members of the intestinal microflora. Another means by which prebiotic oligosaccharides may confer health benefits is via their antiadhesive activity. Specifically, these oligosaccharides may directly inhibit infections by enteric pathogens due to their ability to act as structural mimics of the pathogen binding sites that coat the surface of gastrointestinal epithelial cells. In this study, the ability of commercial prebiotics to inhibit attachment of microcolony-forming enteropathogenic Escherichia coli (EPEC) was investigated. The adherence of EPEC strain E2348/69 on HEp-2 …

Clinical Registered Dietitians, Employers, And Educators Are Interested In Advanced Practice Education And Professional Doctorate Degrees In Clinical Nutrition, Annalynn Skipper, Nancy M. Lewis

Department of Nutrition and Health Sciences: Faculty Publications

A subset of registered dietitians (RDs) is known to practice at an advanced level, but a clear educational pathway supporting advanced medical nutrition therapy practice has not been identified. Thus, an electronic survey was designed to investigate interest of clinical RDs, employers, and educators in advanced practice competencies and professional doctorate degree programs in clinical nutrition. Usable responses were obtained from 440 of 978 (45%) RDs, 61 of 107 (57%) employers, and 76 of 114 (67%) educators. Mean interest (5 = very interested, 1 = very uninterested) in obtaining advanced practice education was highest among RDs (3.93 ±1.01) and was …

Molecular Systematics And Population Structure In The North American Endemic Fish Genus Cycleptus (Teleostei: Catostomidae), Michael Lee Bessert

School of Biological Sciences: Dissertations, Theses, and Student Research

The overarching theme of this research was to investigate hierarchical levels of relatedness in natural populations of the cycleptid fishes (blue suckers), a widespread genus in North America that is of conservation concern throughout. Phylogenetic analysis of mitochondrial DNA sequences revealed that the two described Cycleptus species, C. elongatus and C. meridionalis are not reciprocally monophyletic, yet do not share any haplotypes. Although lineage sorting is incomplete, Bayesian coalescent analyses indicate that the two groups diverged early in the Pleistocene and have been reproductively isolated since. Whether they should be synonymized as C.elongatus and recognized as subspecies is open for …

A Construction Of Twelve Lifelong Learners’ Perspectives: An In-Depth, Naturalistic Study Of Self-Integration Of Learning, Marvin L. Hunt

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This research focuses on understanding people who have chosen to learn throughout their lives. A broad question guided this investigation: What is the rich, lived, lifelong learning experience from the individual’s perspective? This question allowed each participant freedom to explore and define issues he/she considered important relative to lifelong learning. Twelve lifelong learners from a wide range of backgrounds, ages, and experience were serially selected using maximum variation sampling. Most qualitative research uses a priori questions aimed at a specific topic, limiting participants’ discussion. In this study, however, grand tour questions prompted each participant to offer information about lifelong learning …

One Reserve, Three Primates: Applying A Holistic Approach To Understand The Interconnections Among Ring-Tailed Lemurs (Lemur Catta), Verreaux's Sifaka (Propithecus Verreauxi), And Humans (Homo Sapiens) At Beza Mahafaly Special Reserve, Madagascar, James E. Loudon, Michelle L. Sauther, Krista D. Fish, Mandala Hunter-Ishikawa, Youssouf Jacky Ibrahim

Ecological and Environmental Anthropology (University of Georgia)

We applied cultural anthropological, ethological, and parasitological methodologies to investigate the interplay among three primate species, ring-tailed lemurs (Lemur catta), Verreaux’s sifaka (Propithecus verreauxi), and humans (Homo sapiens) who live within the same habitat (i.e. in sympatry) around the Beza Mahafaly Special Reserve, Madagascar. Through a fusion of these methodologies we hope to provide a holistic understanding of the advantages and disadvantages of human-nonhuman primate sympatry. Interviews and questionnaires provided us with initial insights regarding the local peoples' attitudes toward sympatric strepsirrhine primates. Origin myths indicate a close association between humans, ring-tailed lemurs, and …

Human-Nonhuman Primate Interconnections And Their Relevance To Anthropology, Agustin Fuentes

Ecological and Environmental Anthropology (University of Georgia)

The human-nonhuman primate interface is a core component in conservation and an emerging area of discourse across anthropology. There is a growing recognition of the relevance of long-term sympatry between human and nonhuman primates. Until recently these relationships received limited attention in the anthropological literature and in the primatological construction of models for the behavior and evolution of primate societies. Most socioecological investigations into primate groups and human populations do not incorporate their interactions (beyond predation or crop raiding), potential pathogen sharing, or the role of the anthropogenically impacted environment. Current relationships between humans and nonhuman primates are generally assumed …

Sorghum Flour In The El Salvador Baking Industry, Intsormil

INTSORMIL Impacts and Bulletins

The El Salvador baking industry is dependent on imported wheat which results in a loss of valuable foreign exchange. In response, CENTA (Centro Nacional de Tecnologia Agropecuaria y Forestal) scientists with support from INTSORMIL have produced sorghum varieties which have the physical and chemical qualities making them suitable for flour which can be used as a partial substitute for wheat flour in the baking industry, thus decreasing the cost of baked goods. CENTA food technician, Fidelia Herrera pioneered the use of sorghum flour in El Salvador and began helping village bakers utilize sorghum flour back in the 70’s.

Scarab Beetles In Human Culture, Brett C. Ratcliffe

University of Nebraska State Museum: Entomology Papers

The use of scarab beetles (Coleoptera: Scarabaeidae) by primarily pre- and non-industrial peoples throughout the world is reviewed. These uses consist of (1) religion and folklore, (2) folk medicine, (3) food, and (4) regalia and body ornamentation. The use of scarabs in religion or cosmology, once widespread in ancient Egypt, exists only rarely today in other cultures. Scarabs have a minor role in folk medicine today although they may have been more important in the past. The predominant utilization of these beetles today, and probably in the past as well, is as food with emphasis on the larval stage. Lastly, …

Whole-Genome Expression Profiling Defines The Hrpl Regulon Of Pseudomonas Syringae Pv. Tomato Dc3000, Allows De Novo Reconstruction Of The Hrp Cis Element, And Identifies Novel Coregulated Genes, Adriana O. Ferreira, Christopher R. Myers, Jeffrey S. Gordon, Gregory B. Martin, Monica Vencato, Alan Collmer, Misty D. Wehling, James R. Alfano, Gabriel Moreno-Hagelsieb, Warren F. Lamboy, Geneviene Declerck, David J. Schneider, Samuel W. Cartinhour

Department of Plant Pathology: Faculty Publications

Pseudomonas syringae pv. tomato DC3000 is a model pathogen of tomato and Arabidopsis that uses a hypersensitive response and pathogenicity (Hrp) type III secretion system (T3SS) to deliver virulence effector proteins into host cells. Expression of the Hrp system and many effector genes is activated by the HrpL alternative sigma factor. Here, an open reading frame-specific whole-genome microarray was constructed for DC3000 and used to comprehensively identify genes that are differentially expressed in wild-type and ΔhrpL strains. Among the genes whose differential regulation was statistically significant, 119 were upregulated and 76 were downregulated in the wild-type compared with the ΔhrpL …

Child Physical Abuse And Neglect, David K. Dilillo, Andrea R. Perry, Michelle Fortier

Department of Psychology: Faculty Publications

Although poor and inhumane treatment of children is not a new phenomenon (Doerner & Lab, 1998; Wolfe, 1999), child physical abuse and neglect were not identified as serious social problems until the 1960s, with the publication of Kempe and colleagues’ description of battered-child syndrome (Kempe, Silverman, Steele, Droegemueller, & Silver, 1962). In this influential study, Kempe and colleagues described the clinical manifestation of this syndrome in terms of the deleterious physical consequences maltreated children experienced, ranging from undetected outcomes to those that cause significant physical impairments. Rather than exploring the potential psychological sequelae of maltreated children, Kempe focused on detailing …

Reduction In Cholesterol Absorption Is Enhanced By Stearate-Enriched Plant Sterol Esters In Hamsters, Heather E. Rasmussen, David M. Guderian Jr., Curtis A. Wray, Patrick H. Dussault, Vicki L. Schlegel, Timothy P. Carr

Department of Nutrition and Health Sciences: Faculty Publications

Consumption of plant sterol esters reduces plasma LDL cholesterol concentration by inhibiting intestinal cholesterol absorption. Commercially available plant sterol esters are prepared by esterifying free sterols to fatty acids from edible plant oils such as canola, soybean, and sunflower. To determine the influence of the fatty acid moiety on cholesterol metabolism, plant sterol esters were made with fatty acids from soybean oil (SO), beef tallow (BT), or purified stearic acid (SA) and fed to male hamsters for 4 wk. A control group fed no plant sterol esters was also included. Hamsters fed BT and SA had significantly lower cholesterol absorption …

Convergence Of Agriculture And Energy: Implications For Research And Policy, Kenneth Cassman, Vernon Eidman, Eugene Simpson, Larry Berger, Robert Loomis, Marie Walsh, Todd A. Peterson, Edward Runge

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Access to an adequate energy supply at reasonable cost is crucial for sustained economic growth. Unfortunately, oil prices and the need to import from politically unstable countries lowers the reliability of the U.S. energy supply and hinders economic development. Although biofuels have been identified as an important component of the national strategy to decrease U.S. dependence on imported oil, the ability to sustain a rapid expansion of biofuel production capacity raises new research and policy issues. This document seeks to identify the most critical of these issues to help inform the policy development process. The goal is to enhance the …

Linking Life Zones, Life History Traits, Ecology, And Spatial Cognition In Four Allopatric Southwestern Seed Caching Corvids, Russell P. Balda, Alan Kamil

Papers in Behavior in Biological Sciences

This report will review the similarities and differences of four species of pine seed caching members of the avian family Corvidae that live on the slopes and base of the San Francisco Peaks in north-central Arizona. The four species include the Clark’s nutcracker (Nucifraga columbiana), pinyon jay (Gymnorhinus cyanocephalus), western scrub-jay (Aphelocoma californica), and Mexican jay (A. ultramarina). These corvids demonstrate a specialization gradient for the harvesting, transporting, caching and recovering of buried pine seeds. This gradient is reflected in their dependence on cached pine seeds for winter and early spring survival …

Plant Reproductive Allocation Predicts Herbivore Dynamics Across Spatial And Temporal Scales, Tom E. X. Miller, Andrew J. Tyre, Svata M. Louda

School of Biological Sciences: Faculty Publications

Life-history theory suggests that iteroparous plants should be flexible in their allocation of resources toward growth and reproduction. Such plasticity could have consequences for herbivores that prefer or specialize on vegetative versus reproductive structures. To test this prediction, we studied the response of the cactus bug (Narnia pallidicornis) to meristem allocation by tree cholla cactus (Opuntia imbricata). We evaluated the explanatory power of demographic models that incorporated variation in cactus relative reproductive effort (RRE; the proportion of meristems allocated toward reproduction). Field data provided strong support for a single model that defined herbivore fecundity as a …

Extension Wildlife Programs: Thoughts And Ideas, Jeffrey J. Jackson

Triennial National Wildlife and Fisheries Extension Specialists Conference: 11th (2006)

The following commentary is a summary of some personal thoughts, reflections, and opinions on extension wildlife programming based on my experience at the University of Georgia as Extension Wildlife Specialist during the years between 1976 and 2001. I hope it will be of some value to new specialists. Because I was the only Extension Wildlife Specialist, I was in a unique position to develop an overview of the entire wildlife management field. Along the way, I had the opportunity to be full time within Extension, have a split appointment, and be assigned to an academic department.

First-Stop Planning And Communication For Landhelp, Delwin E. Benson

Triennial National Wildlife and Fisheries Extension Specialists Conference: 11th (2006)

I developed an Internet-based, planning and communication system for professional and private users to make plans for their lands, which is branded as LandHelp (www.LandHelp.info). The project was funded by grants from the Renewable Resources Extension Act, Natural Resources Conservation Service (NRCS) Wildlife Habitat Management Institute, Colorado State Forest Service, United States Department of Agriculture, Sustainable Agriculture Research and Education (USDA SARE) from the Western Region, and the United States Department of Agriculture (USDA) Agro-forestry program with the NRCS. Currently, LandHelp contains links to 31 broad categories of information that then link to 2,613 more resources. Major topics include, but …

An Internet Survey Of Private Pond Owners And Managers In Texas, Michael P. Masser, April E. Schonrock

Triennial National Wildlife and Fisheries Extension Specialists Conference: 11th (2006)

The primary emphasis of this survey was to determine what specific problems Texas private impoundment owners/managers confront, how widely these problems occur, and where owners/managers get their information on pond management. A secondary emphasis was to examine the potential utilization of the Internet to gather information and distributed outreach materials. A random sample of 2,999 private impoundment (i.e., no public waters) applicants for Triploid Grass Carp Permits from Texas Parks and Wildlife was utilized as the survey mailing list. A 49-question survey was developed and placed on a secure web site. Each questionnaire contained five sections: general pond characteristics, physical …

The Above-Ground Movement And Dispersal Of The Plains Pocket Gopher (Geomys Bursarius), Craig Panich

Triennial National Wildlife and Fisheries Extension Specialists Conference: 11th (2006)

The Plains pocket gopher has the largest range of its genus, and it is the gopher that inhabits much of Wisconsin. Gophers are fossorial herbivores that have a dramatic impact on natural and agricultural ecosystems. Throughout the summer of 2005, I completed a population analysis of the plains pocket gopher in a variety of habitats in Buffalo and Trempealeau Counties, Wisconsin, that provided valuable insight into the complex population dynamics of the gopher and served as a foundation to this project. Pocket gophers are known to be strictly subterranean; however, it is not uncommon to find their remains inside the …

Saving The World One Native Plant At A Time, Christopher E. Moorman, Christopher S. Deperno

Triennial National Wildlife and Fisheries Extension Specialists Conference: 11th (2006)

Wildlife habitat is lost as the human population and land clearing for development increase in the South. Remaining habitats are fragmented and contain high numbers of invasive, exotic plants. Suburban, manicured landscapes often lack the plant diversity and complex vegetation structure important to wildlife. Generally, developers and homeowners replant cleared grounds with exotic plants that don’t provide quality wildlife habitat. Instead, individual home or property owners can mitigate wildlife habitat loss in urban areas by landscaping with native plants following proper design principles. Furthermore, many people taking action over a large area (e.g., across a neighborhood) will help connect small …

An Introduction To The Revised Southern Region 4-H Wildlife Projects, Renee Strnad, Chris Moorman

Triennial National Wildlife and Fisheries Extension Specialists Conference: 11th (2006)

During the 1970s, a partnership between the United States Department of Agriculture and the National 4-H Council led to the creation of the Southern Region Wildlife Project materials. Fifty-one publications, based on a variety of fish and wildlife-related subject matter, were created. In 1999, the North Carolina Department of 4-H and Youth Development received a grant from the United States Fish and Wildlife Service to revise the publications. Twenty-four of the original 51 publications were selected for revision by Extension Specialists and other wildlife biologists in several southern states. Content and format for the projects were updated in the revised …

Responding To The Storm: Exploring The Psychological Support Of Emergency Responders After The May 2004 Storms In Southeast Nebraska, Denise Bulling, Stacey Hoffman, Martin Klein, Brooke Olsen, Harry Walles

University of Nebraska Public Policy Center: Publications

A large number of emergency personnel were involved in the response to the May 2004 storms that devastated a 52 mile swath of Southeast Nebraska. Emergency workers who responded the night of the storm were exposed to bad weather, darkness, and uncertainty about their own safety. Later, they were asked to work alongside survivors and neighbors who had lost everything amidst widespread destruction of farms, homes, and businesses. Some, but not all of the emergency personnel were offered formal psychological support services like critical incident debriefing to assist with the emotional processing of the event.

The research literature is mixed …

Pan Rey Bakery, El Salvador Tests Sorghum Flour, Intsormil

INTSORMIL Impacts and Bulletins

Pan Rey, the “Bread King,” a large commercial bakery located at Quezaltepeque, El Salvador is testing sorghum flour as a substitute for wheat. The Pan Rey Bakery collaborates with the CENTA Food Technology Laboratory in a project to promote the use of sorghum flour in large bakeries. Many small, village level bakeries, such as the bakery of Clemencia Barrera in San Rafael Cedro, El Salvador (see INTSORMIL Report No. 5), have been using sorghum flour as a substitute for wheat for many years. However, use of sorghum flour on a large scale in the big commercial bakeries, such as Pan …
