Building Better Scientists Through Cross-Disciplinary Collaboration In Synthetic Biology: A Report From The Genome Consortium For Active Teaching Workshop 2010, Michael J. Wolyniak, Consuelo J. Alvarez, Vidya Chandrasekaran, Theresa M. Grana, Andrea Holgado, Christopher J. Jones, Robert W. Morris, Anil L. Pereira, Joyce Stamm, Talitha M. Washington, Yixin Yang

Biological Sciences Research

A common problem faced by primarily undergraduate institutions is the lack of funding and material support needed to adequately expose students to modern biology, including synthetic biology. To help alleviate this problem, the Genome Consortium for Active Teaching (GCAT) was founded in 2000 by Malcolm Campbell at Davidson College to bring genomics into the undergraduate curriculum. GCAT’s first tangible activity was to serve as a central clearinghouse both for the purchase and reading of DNA microarrays and for information on how to execute genomics experiments at undergraduate institutions. In response to the evolution of molecular biology in the last decade, …

An Exploratory Study Of The Career Aspirations And Self-Perceptions Of University Honors Program Students, Pamela Malone Gresham

The current trend in education, especially gifted and talented education, focuses on science, technology, engineering, and mathematics (STEM). How has this impacted the gifted and talented population when they become young adults ready to pursue college and careers? Are the interests and skills of University Honors Program students aligned with the majors they have chosen? What are their interests and skills? The research was conducted on the campus of Indiana State University. This is a public higher education campus whose University Honors Program …

The Eminence Of Imminence And The Myopia Of Markets, Teneille R. Brown

Utah Law Faculty Scholarship

This article questions the privileging of disaster, or imminent threat, over more distant threats to public health. In many cases, this privileging makes sense as we do not have time to evaluate the threat under traditional frameworks. But in some cases, we privilege disaster in ways that may be ethically and legally unsound. Here I am interested in a particular type of public health threat – the negative consequences that stem from climate change. In this article I view the climate change discussion through the lens of distributive justice. I analyze the ethical as well as legal arguments for encouraging …

Leiomyosarcoma Arising In The Pancreatic Duct: A Case Report And Review Of The Current Literature, Nicole D. Riddle, Brian C. Quigley, Irwin Browarsky, Marilyn M. Bui

Pathology and Cell Biology Faculty Publications

Context. Leiomyosarcomas are rare malignant smooth muscle tumors that may arise in any organ or tissue that contains smooth muscle, commonly within the gastrointestinal tract. They are most often found in the stomach, large and small intestines, and retroperitoneum. Primary pancreatic leiomyosarcoma is extremely rare, and to the best of our knowledge only 30 cases have been reported in the world literature since 1951. Our case represents the first to have a clear origin from the main pancreatic duct. Case Report. This case was diagnosed in a large, tertiary care center in Tampa, Florida. Pertinent information was obtained …

Effects Of Co-Products And Breed Of Sire On The Performance, Carcass Characteristics, And Rates Of Ultrasound Backfat And Marbling Deposition In Feedlot Cattle, C. O. Trejo, D. B. Faulkner, A. Shreck, J. W. Homm, T. G. Nash, S. L. Rodriguez-Zas, L. L. Berger

Department of Animal Science: Faculty Publications

Recently, high prices have driven producers to replace corn partially or totally with more affordable ingredients. A total of 1,256 DNA-validated progeny from Angus (n = 241), Simmental (n = 599), Simmental × Angus (SA; n = 296), and 75% Simmental (75S; n = 120) sires were used to evaluate the effects of feedlot nutrition and sire breed on the performance, carcass characteristics, and rates of ultrasound backfat and marbling deposition in feedlot cattle. Diets included corn or a corn co-product: dried distillers grains with solubles (DDGS), fresh wet distillers grains, wet corn gluten feed, stored wet distillers grains, or …

Generating ‘As-Applied’ Pesticide Distribution Maps From A Self-Propelled Agricultural Sprayer Based On Nozzle Pressure Data, Joe D. Luck, Ajay Sharda, Santosh Pitla, John P. Fulton, Scott A. Shearer

Department of Animal Science: Faculty Publications

The application of pre-emergence, post-emergence, and burn-down herbicides (i.e., glyphosate) continues to increase as producers attempt to reduce both negative environmental impacts from tillage and input costs from labor, machinery and materials. The use of precision agriculture technologies such as automatic boom section control allows producers to reduce off-target application when applying herbicides. While automatic boom section control provides benefits, pressure differences across the spray boom resulting from boom section actuation can lead to off-rate application errors. Off-rate errors may also result from spray rate controller compensation for ground speed changes and velocity variation across the spray boom during turning …

Low-Cost Obstacle Detection Sensor Array For Unmanned Agricultural Vehicles, Santosh Pitla, Joe D. Luck, Scott A. Shearer

Department of Animal Science: Faculty Publications

Mobile robots deployed for agricultural applications must operate in harsh environments where they encounter a variety of both moveable and immovable obstacles. Typically, robots utilize vision sensors to learn about the environment in which they are working. In this study, a low-cost infra-red (IR) sensor array was developed to act as an obstacle detection aid for an unmanned agricultural vehicle (UAgV). The IR sensor array developed consists of six IR sensors mounted on two orthogonal steel plates. The array of sensors was continuously oscillated about the yaw-axis to traverse a 200⁰ field of view in front of the UAgV. …

Pneumatic Control Of A Variable Orifice Nozzle, Joe D. Luck, Michael P. Sama, Santosh Pitla, Scott A. Shearer

Department of Animal Science: Faculty Publications

A variable-orifice nozzle with droplet optimization was recently developed and introduced for use on agricultural sprayers. The VariTarget (VT) nozzle reacts to changes in the system flow rate via a metering assembly that is controlled by a diaphragm and spring. As the liquid pressure changes, the VT metering assembly attempts to control the flow rate and spray pattern exiting the nozzle. The goal of this study was to replace the spring controlled “reactive” system with a pneumatically controlled metering assembly. The proposed system would allow for the metering assembly to adjust the flow rate and spray pattern exiting the nozzle …

Detection, Validation, And Downstream Analysis Of Allelic Variation In Gene Expression, Daniel C. Ciobanu, Lu Engle, Khyobeni Mozhui, Xusheng Wang, Manjunatha Jagalur, John A. Morris, William L. Taylor, Klaus Dietz, Perikles Simon, Robert W. Williams

Department of Animal Science: Faculty Publications

Common sequence variants within a gene often generate important differences in expression of corresponding mRNAs. This high level of local (allelic) control—or cis modulation—rivals that produced by gene targeting, but expression is titrated finely over a range of levels. We are interested in exploiting this allelic variation to study gene function and downstream consequences of differences in expression dosage. We have used several bioinformatics and molecular approaches to estimate error rates in the discovery of cis modulation and to analyze some of the biological and technical confounds that contribute to the variation in gene expression profiling. Our analysis of SNPs …

Stress is a major risk factor for numerous neuropsychiatric diseases. However, susceptibility to stress and the qualitative nature of stress effects on behavior differ markedly among individuals. This is partly because of the moderating influence of genetic factors. Inbred mouse strains provide a relatively stable and restricted range of genetic and environmental variability that is valuable for disentangling gene–stress interactions. Here, we screened a panel of inbred strains for anxiety- and depression-related phenotypes at baseline (trait) and after exposure to repeated restraint. Two strains, DBA/2J and C57BL/6J, differed in trait and restraint-induced anxiety-related

behavior (dark/light exploration, elevated plus maze). Gene …

Cognitive Representation In Transitive Inference: A Comparison Of Four Corvid Species, Alan B. Bond, Cynthia A. Wei, Alan C. Kamil

Alan Bond Publications

During operant transitive inference experiments, subjects are trained on adjacent stimulus pairs in an implicit linear hierarchy in which responses to higher ranked stimuli are rewarded. Two contrasting forms of cognitive representation are often used to explain resulting choice behavior. Associative representation is based on memory for the reward history of each stimulus. Relational representation depends on memory for the context in which stimuli have been presented. Natural history characteristics that require accurate configural memory, such as social complexity or reliance on cached food, should tend to promote greater use of relational representation. To test this hypothesis, four corvid species …

Ducks, Geese, And Swans Of The World, Revised Edition [Complete Work], Paul A. Johnsgard

Ducks, Geese, and Swans of the World by Paul A. Johnsgard

The only one-volume comprehensive survey of the family Anatidae available in English, this book combines lavish illustration with information on the natural history, distribution and status, and identification of all the species.

After an introductory discussion of the thirteen tribes of Anatidae, separate accounts follow for each of the nearly 150 recognized species. These include scientific and vernacular names (in French, German, and Spanish as well as English), descriptions of the distribution of all recognized subspecies, selected weights and measurements, and identification criteria for both sexes and various age classes. The “Natural History” section of each species account considers habitats, …

Ducks, Geese, And Swans Of The World: Tribe Merganettini (Torrent Duck), Paul A. Johnsgard

Ducks, Geese, and Swans of the World by Paul A. Johnsgard

Torrent Duck
This remarkable stream-dwelling duck of the Andean mountains is certainly one of the most specialized of all waterfowl, and in part its anatomical and behavioral specializations have obscured its basic relationships, which appear to be with either the perching ducks or the dabbling ducks. In the absence of definitive evidence, it seems reasonable to maintain a separate tribe for this species, which exists as a series of relatively isolated populations between Venezuela and Tierra del Fuego that vary greatly in male plumage characteristics. Torrent ducks are essentially cavity- or ledge-nesting forms, although only a few nests have been …

Chapter 6 - Humanizing Academic Accountability: Embedded Assessment Gets At The Heart Of Teaching And Learning, Peggy Liggit

The Scholarship of Teaching and Learning at EMU

Assessment of student learning and academic program review are requirements for institutional accreditation. Faculty tend to "push back" against this work because it feels more like a mandate for accountability rather than a natural part of instruction. In this chapter, I describe the ways in which embedded assessment served within our program documentation system, and I provide examples of what this type of assessment looks like from the work our department had accomplished in the last year. My intention here is to pose the idea of using embedded assessment as an alternative model, or a supplement to the traditional models, …
