The Human Gut Microbiome: Ecology And Recent Evolutionary Changes, Jens Walter, Ruth Ley

Department of Food Science and Technology: Faculty Publications

The human gastrointestinal tract is divided into sections, allowing digestion and nutrient absorption in the proximal region to be separate from the vast microbial populations in the large intestine, thereby reducing conflict between host and microbes. In the distinct habitats of the gut, environmental filtering and competitive exclusion between microbes are the driving factors shaping microbial diversity, and stochastic factors during colonization history and in situ evolution are likely to introduce intersubject variability. Adaptive strategies of microbes with different niches are genomically encoded: Specialists have smaller genomes than generalists, and microbes with environmental reservoirs have large accessory genomes. A shift …

Immune Evasion Of Porcine Reproductive And Respiratory Syndrome Virus Through Glycan Shielding Involves Both Glycoprotein 5 As Well As Glycoprotein 3, Hiep Vu, Byungjoon Kwon, Kyoung-Jin Yoon, William W. Laegreid, Asit K. Pattnaik, Fernando A. Osorio

School of Veterinary and Biomedical Sciences: Faculty Publications

Passive administration of porcine reproductive and respiratory syndrome virus (PRRSV) neutralizing antibodies (NAbs) can effectively protect pigs against PRRSV infection. However, after PRRSV infection, pigs typically develop a weak and deferred NAb response. One major reason for such a meager NAb response is the phenomenon of glycan shielding involving GP5, a major glycoprotein carrying one major neutralizing epitope. We describe here a type II PRRSV field isolate (PRRSV-01) that is highly susceptible to neutralization and induces an atypically rapid, robust NAb response in vivo. Sequence analysis shows that PRRSV-01 lacks two N-glycosylation sites, normally present in wild-type (wt) PRRSV strains, …

Secretive Marsh Bird Species Co-Occurrences And Habitat Associations Across The Midwest, Usa, Jason R. Bolenbaugh, Sarah E. Lehnen, David G. Krementz

United States Geological Survey: Staff Publications

Because secretive marsh birds are difficult to detect, population status and habitat use for these birds are not well known. We conducted repeated surveys for secretive marsh birds across 264 sites in the Upper Mississippi River and Great Lakes Joint Venture region to estimate abundance, occupancy, and detection probabilities during the 2008 and 2009 breeding seasons. We identified species groups based on observed species co-occurrences. Two species, least bittern Ixobrychus exilis and American bittern Botaurus lentiginosus, co-occurred with other species less often than expected by chance, and two species groups, rails (Virginia rail Rallus limicola and sora Porzana carolina) and …

A Viking Age Political Economy From Soil Core Tephrochronology, Kathryn Anne Catlin

Graduate Masters Theses

Saga accounts describe Viking Age Iceland as an egalitarian society of independent household farms. By the medieval period, the stateless, agriculturally marginal society had become highly stratified in exploitative landlord-tenant relationships. Classical economists place the origin of differential wealth in unequal access to resources that are unevenly distributed across the landscape. This irregularity is manifested archaeologically as spatial variations in buried soil horizons, which are addressed through thousands of soil cores recorded across Langholt in support of the Skagafjörður Archaeological Settlement Survey. Soil accumulation rates, a proxy for land quality, are derived from tephrochronology and correlated with archaeological and historical …

Nutrition And Stature: The Residents Of The Island Of Gotland, Sweden Killed In The Battle Of Wisby, 1361, Michelle A. Miller

Masters Theses

This research examines stature in order to assess the socio-economic status of Gotland, an island (and municipality) off the coast of Sweden, before the 1360's. Gotland was known as a wealthy and autonomous peasant republic although it was loosely ruled by the Swedish Crown. In 1361, the Danish Army laid siege on the seaport city of Wisby to obtain its riches. Three days after the battle, the approximately 1800 dead Gotlanders were tossed haphazardly into five common graves. Archaeological excavations took place from 1905-1930 by Bendt Thordeman, among others. The human remains were analyzed in 1937. Osteological analysis in the …

Property Rights In Post-Conflict Sri Lanka, Ryan P. Anderson, E. Wesley F. Peterson

Cornhusker Economics

This is the third and final article in a series on property rights. In the previous two articles we saw how conflicts often emerge during the transition from one set of legal or social institutions to another. In this article we consider how such challenges helped spark a prolonged civil war in Sri Lanka, and how they might finally be resolved now that peace has been realized.

Using Service Responsibility Tables To Supplement Uml In Analyzing E-Service Systems, Xin Tan, Steven Alter, Keng Siau

Research Collection School Of Computing and Information Systems

This paper proposes using Service Responsibility Tables (SRTs) as a tool in analyzing e-service systems. First it discusses difficulties and deficiencies of using formal modeling languages such as UML in analyzing e-service systems. It proposes using SRTs as an informal language and lightweight analytical tool to be used by business professionals in analyzing e-service systems. SRTs are based on a service value chain framework but do not rely on abstract concepts and constructs, and therefore can be used by business professionals to supplement UML. We suggest a set of heuristics for transforming SRTs into two key UML diagrams, thereby illustrating …

Distributed Learning With Biogeography-Based Optimization, Carre Scheidegger, Arpit Shah, Daniel J. Simon

Electrical and Computer Engineering Faculty Publications

We present hardware testing of an evolutionary algorithm known as biogeography-based optimization (BBO) and extend it to distributed learning. BBO is an evolutionary algorithm based on the theory of biogeography, which describes how nature geographically distributes organisms. We introduce a new BBO algorithm that does not use a centralized computer, and which we call distributed BBO. BBO and distributed BBO have been developed by mimicking nature to obtain an algorithm that optimizes solutions for different situations and problems. We use fourteen common benchmark functions to obtain results from BBO and distributed BBO, and we also use both algorithms to optimize …

Digitisation's Impacts On Publics: Public Knowledge And Civic Conversation, Alessandro Lovari, Soojin Kim, Kelly Vibber, Jeong-Nam Kim

Research Collection Lee Kong Chian School Of Business

This paper proposes a new way of classifying publics in terms of their adoption and use of digitalised communication technologies. A CATI (computer aided telephone interview) survey of 1,014 citizens revealed that people in Siena, Italy, show different patterns and gaps in adopting new media and technologies as well as in using them in their civic participation and engagement. Based on the survey results, four types of publics are suggested (inactive, analogical, hybrid, and digital publics) and a demographic profile of each public including age, gender, and education is provided. The relationships among public types, level of education, and gender …

Habitat Selection By Female Swift Foxes (Vulpes Velox) During The Pup- Rearing Season, Indrani Sasmal, Jonathan A. Jenks, Troy W. Grovenburg, Shubham Datta, Greg. M. Schroeder, Robert W. Klaver, Kevin M. Honness

The Prairie Naturalist

The swift fox (Vulpes velox) was historically distributed in western South Dakota including the region surrounding Badlands National Park (BNP). The species declined during the mid-1800s, largely due to habitat loss and poisoning targeted at wolves (Canis lupis) and coyotes (C. latrans). Only a small population of swift foxes near Ardmore, South Dakota persisted. In 2003, an introduction program was initiated at BNP with swift foxes translocated from Colorado and Wyoming. We report on habitat use by female swift foxes during the pup-rearing season (May–July) in 2009. Analyses of location data from 13 radiomarked female foxes indicated disproportional use (P < 0.001) of some habitats relative to their availability within swift fox home ranges. Swift foxes used grassland (ŵ = 1.01), sparse vegetation (ŵ = 1.43) and prairie dog towns (ŵ = 1.18) in proportion to their availability, whereas they were less likely to use woodland (ŵ = 0.00), shrubland (ŵ = 0.14), pasture/agricultural-land (ŵ = 0.25) and development (ŵ = 0.16) relative to availability. Swift foxes typically are located in habitats that provide greater visibility, such as shortgrass prairie and areas with sparse vegetation; which allow detection of approaching coyotes (e.g., primary predator of swift foxes).

Distribution Of Crayfish Species In Select North Dakota Streams, Cari-Ann Hayer, Terrance L. Velazquez, Mclain S. Johnson, Brian Graeb

The Prairie Naturalist

Crayfish have an integral role in aquatic ecosystems, serving as herbivores, predators, detritivores, and prey for fishes and other aquatic and terrestrial animals (Momot 1995, Taylor et al. 1996, Martin 1997). Many crayfish populations are currently declining as a result of habitat alteration (Taylor et al. 1996) and invasive predators (e.g., rusty crayfish Orconectes rusticus [Girard; Lodge et al. 2000]). Knowledge of crayfish distribution and biology in North America and specifically North Dakota is sparse or lacking (Taylor et al. 1996) and baseline information is necessary to identify effects of anthropogenic alterations. Early inventories documented 3 crayfish species in North …

Prevalence Of Myxobolus Cerebralis Infections Among Genetic Lineages Of Tubifex Tubifex At Three Locations In The Madison River, Montana, Nilanjan Lodh, Lori Stevens, Billie Kerans

Clinical Lab Sciences Faculty Research and Publications

Host biodiversity can impact disease risk and influence the transmission of parasitic disease. Stream sediment–dwelling worms, Tubifex tubifex (Clitellata: Oligochaeta), are the definitive host of the parasite Myxobolus cerebralis (Myxozoa: Myxosporea), which causes whirling disease in salmonid fishes. Genetic diversity of T. tubifex is correlated with host susceptibility to M. cerebralis, and mitochondrial Lineage III is generally shown to be more likely to be infected and produce the triactinomyxon (TAM) spores than other lineages. We determined the mitochondrial lineage, relative abundance, and prevalence of infection of T. tubifex collected at 3 sites in the Madison River, Montana, where previous …

Thinking About Peace, Conflict, And War: An Introduction To The Special Issue, Sondra J. Fogel, Daniel Liechty

The Journal of Sociology & Social Welfare

This special issue had humble beginnings. As a matter of fact, odds were stacked against it, especially given that the original plan for this topic was for a panel discussion based on submitted work to the 2009 Society for the Study of Social Problems (SSSP) Conference. However, not one abstract was received for this topic. I found this quite curious and alarming since at that time this country was engaged in two wars, there was continuous media coverage around "terrorist" activities, and we were experiencing frequent changes to our daily routines based on new security measures. Anti-war protestors were growing …

Cross Talk Between O-Glcnacylation And Phosphorylation: Roles In Signaling, Transcription, And Chronic Disease, Gerald W. Hart, Chad Slawson, Genaro A. Ramirez-Correa, Olof Lagerlof

School of Medicine Publications

O-GlcNAcylation is the addition of β-D-N-acetylglucosamine to serine or threonine residues of nuclear and cytoplasmic proteins. O-linked N-acetylglucosamine (O-GlcNAc) was not discovered until the early 1980s and still remains difficult to detect and quantify. Nonetheless, O-GlcNAc is highly abundant and cycles on proteins with a timescale similar to protein phosphorylation. O-GlcNAc occurs in organisms ranging from some bacteria to protozoans and metazoans, including plants and nematodes up the evolutionary tree to man. O-GlcNAcylation is mostly on nuclear proteins, but it occurs in all intracellular compartments, including mitochondria. Recent glycomic analyses have shown that O-GlcNAcylation has surprisingly extensive …

The Consumer Financial Protection Bureau's Appointment With Trouble, Kent H. Barnett

Scholarly Works

This article considers whether the Consumer Financial Protection Bureau Director’s appointment of the Bureau’s Deputy Director comports with the Appointments Clause. The Dodd-Frank Wall Street Reform and Consumer Protection Act established the Bureau in July 2010, as well as the offices of the Bureau’s Director and Deputy Director, to coordinate the regulation and enforcement of federal consumer-financial-protection laws. Under that act, the Director appoints the Deputy Director. The Appointments Clause permits “Heads of Departments” to appoint inferior officers like the Deputy Director. But it is unclear if the Bureau is a “department” and thus if the Director is a department …

The Limits Of Procedural Private Ordering, Jaime L. Dodge

Scholarly Works

Civil procedure is traditionally conceived of as a body of publicly-set rules, with limited carve-outs – most commonly, forum selection and choice of law provisions. I argue that these terms are mere instantiations of a broader, unified phenomenon of procedural private ordering, in which civil procedure is no longer irrevocably defined by law, but instead is a mere default that can be waived or modified by contract. Parties are no longer merely selecting between publicly-created procedural regimes but customizing the rules of procedure to be applied by the court – from statutes of limitations, discovery obligations and the admissibility of …

Things Are In People, People Are In Things: A Phenomenological Approach To H.D.'S Hermione And The Modernist Prosthetic Body, Alison Stone Roberg

Theses and Dissertations

H.D.'s autobiographical novel HERmione is phenomenological in texture. It portrays both sides of a dynamic process: the individual "creates" the world by adjusting a "psychic lens," projecting a mental space in which objects can appear; yet at the same time, the world imposes itself on the sensing subject. The framework within which this dynamic process occurs is the body; as the novel portrays, the body is the site of juxtapositions and transformations as it comes into contact with the world. In this article, I discuss the ways in which H.D. explores the boundaries and intersections between the human body and …

Heat Shock Proteins As Novel Cancer Therapeutics: Targeting The Hallmarks Of Cancer, Chao Li

Theses and Dissertations

Molecular chaperones, commonly known as heat shock proteins (HSPs), are essential for mammalian cells to maintain homeostasis, and HSPs function by inducing an ATPase-coupled structural change, followed by interactions with diverse co-chaperones and over 200 client proteins implicated in many critical signaling networks. These highly expressed HSPs participate in the onset and progression of several human diseases including cancer, and their connection with tumorigenesis has facilitated research and clinical trials related to targeting HSPs as a novel anti-tumor therapy. The predominant mechanism of chaperone inhibition is through either disruption of the HSP association with client protein or an altered binding …

Locating Child Protection In Preservice Teacher Education, Kerryann Walsh, Louise Laskey, Elspeth Mcinnes, Ann Farrell, Ben Mathews, Freda Briggs

Australian Journal of Teacher Education

A recent report delivered by the Australian Centre for Child Protection has highlighted the need for empirical evidence of effective pedagogies for supporting teaching and learning of child protection content in Australian teacher education programs (Arnold & Maio-Taddeo, 2007). This paper advances this call by presenting case study accounts of different approaches to teaching child protection content in University-based teacher education programs across three Australian States. These different cases provide a basis for understanding existing strategies as an important precursor to improving practice. Although preschool, primary and secondary schools have been involved in efforts to protect children from abuse and …

Model Predictive Control Of Blood Pressure By Drug Infusion, Taghreed M.

Iraqi Journal of Computers, Communications, Control and Systems Engineering

In this research the design of a Model Predictive Controller (MPC) is investigated for regulating Mean Arterial Pressure (MAP) by infusing the Sodium Nitro-Prusside (SNP) drug to the mathematical model of human patients during surgical operations where the blood pressure suffers from sudden rises due to multiple causes. The MPC is designed and compared with digital Proportional-Integral (PI) controller. MPC is chosen due to its known ability of estimating an optimal control action and dealing with input, state constraints and with disturbances. Simulation results for three patients' MAP models controlled by MPC and PI controllers that are designed for a …
