The Use Of Strategic Forces To Understand Competitive Advantages Provided By Information Technology, Gerald E. Evans, Clyde Neu

Journal of International Technology and Information Management

Porter’s Five Forces model of business strategy is foundational to understanding strategic forces and the role of information technology in the larger strategic framework of an organization. The authors describe how information technology changes the strength and/or influence of the competitive forces in Porter’s model. Furthermore, understanding how specific technologies potentially change specific forces within Porter’s model is the foundation of IT strategy. This theoretical framework of strategic alignment is developed through cases demonstrating how specific technologies change the strategic forces within specific industries and how organizations should take advantage of these changing forces. Empirical evidence for the validity of …

Migraine-Associated Vestibulopathy, Julie A. Honaker, Ravi N. Samy

Department of Special Education and Communication Disorders: Faculty Publications

Purpose of review: In the past few years, otologists have been seeing an increasing number of patients with vestibular disorders due to migraine- associated vestibulopathy. This article reviews some of the latest developments in the understanding of this disease process, specifically its incidence, symptoms, diagnosis, and treatment.
Recent findings: Migraine-associated vestibular symptoms may include episodic true vertigo, movement-provoked dysequilibrium, imbalance/unsteadiness, and complaints of lightheadedness. The pathophysiology of migraine-associated vestibulopathy is not completely understood; however, both peripheral and central deficits have been observed. Although the International Headache Society classification does not include migraine-associated vestibulopathy as a subclassification of migraine, there is …

Dimensionality Of Thoughts Of Death And Suicide: Evidence From A Study Of Homeless Adolescents, Kevin A. Yoder, Les B. Whitbeck, Dan R. Hoyt

Department of Sociology: Faculty Publications

This study used data from a sample of 444 homeless adolescents to determine whether thoughts of death and suicide form one construct (unidimensionality) or two distinct but correlated constructs (multi-dimensionality). Thoughts of death and suicide were common in the sample; over two-thirds of the adolescents positively endorsed at least one of the eight death-or suicide-related items. Evidence regarding dimensionality was mixed. Exploratory factor analysis results and similarity coefficients supported one construct; confirmatory factor analysis and external consistency results provided evidence for two constructs. The results were reconciled by considering suicidality as a continuum from thoughts of death to suicidal ideation, …

Nitrated Alpha-Synuclein-Activated Microglial Profiling For Parkinson’S Disease, Ashley D. Reynolds, Jason G. Glanzer, Irena Kadiu, Mary Ricardo-Dukelow, Anathbandhu Chaudhuri, Pawel Ciborowski, Ronald Cerny, Benjamin Gelman, Mark P. Thomas, R. Lee Mosley, Howard E. Gendelman

Ronald Cerny Publications

(PD). This can occur, in part, by modulation of glial function following activation by soluble or insoluble modified alphasynuclein (α-syn), a chief component of Lewy bodies that is released from affected dopaminergic neurons. α-Syn is nitrated during oxidative stress responses and in its aggregated form, induces inflammatory microglial functions. Elucidation of these microglial function changes in PD could lead to new insights into disease mechanisms. To this end, PD-associated inflammation was modeled by stimulation of microglia with aggregated and nitrated α-syn. These activated microglia were ameboid in morphology and elicited dopaminergic neurotoxicity. A profile of nitrated, aggregated α-syn-stimulated microglia was …

Liangcheng Du Publications

The level of mycotoxin fumonisins in corn-based food and feed collected from Linxian County, a high-risk area for esophageal cancer in China, has been analyzed using high-performance liquid chromatographic coupled with evaporative laser scattering detector (HPLC-ELSD). A total of 104 corn kernel samples were obtained from local households, granaries, wholesale markets (central markets), and retail markets (stores and supermarkets). Fumonisin B1 (FB1) was detected in the samples from households, granaries, central markets, and stores, with a positive rate of 61.5%, 50%, 33.3%, and 17%, respectively. No fumonisin was detected in samples from the supermarket. The highest FB1 levels (0.30–3.20 μg/ …

Mechanisms Of Hemoglobin Adaptation To High Altitude Hypoxia, Jay F. Storz, Hideaki Moriyama

Hideaki Moriyama Publications

Evidence from a number of vertebrate taxa suggests that modifications of hemoglobin (Hb) function may often play a key role in mediating an adaptive response to high altitude hypoxia. The respiratory functions of Hb are a product of the protein’s intrinsic O₂-binding affinity and its interactions with allosteric effectors such as protons, chloride ions, CO₂, and organic phosphates. Here we review several case studies involving high altitude vertebrates where it has been possible to identify specific mechanisms of Hb adaptation to hypoxia. In addition to comparative studies of Hbs from diverse animal species, functional studies of …

Endogenous And Exogenous Control Of Ecosystem Function: N Cycling In Headwater Streams, H. M. Valett, S. A. Thomas, P. J. Mulholland, J. R. Webster, C. N. Dahm, C. S. Fellows, C. L. Crenshaw, C. G. Peterson

School of Biological Sciences: Faculty Publications

Allochthonous inputs act as resource subsidies to many ecosystems, where they exert strong influences on metabolism and material cycling. At the same time, metabolic theory proposes endogenous thermal control independent of resource supply. To address the relative importance of exogenous and endogenous influences, we quantified spatial and temporal variation in ecosystem metabolism and nitrogen (N) uptake using seasonal releases of ¹⁵N as nitrate in six streams differing in riparian–stream interaction and metabolic character. Nitrate removal was quantified using a nutrient spiraling approach based on measurements of downstream decline in ¹⁵N flux. Respiration (R) and gross primary production (GPP) …

Experimental Analysis Of A Web-Based Training Intervention To Develop Positive Psychological Capital, Fred Luthans, James B. Avey, Jaime L. Patera

Department of Management: Faculty Publications

Psychological capital with components of hope, self-efficacy, optimism, and resiliency has recently emerged as a core construct in taking positive psychology to the workplace. A distinguishing feature is that it is “state-like” and thus open to development. We analyze whether such psychological capital can be developed through a highly focused, 2-hour web-based training intervention. Using a pretest, posttest experimental design (n = 187 randomly assigned to the treatment group and n = 177 to the control group), we found support that psychological capital can be developed by such a training intervention.

Parasite Pathoecology Of Salmon Pueblo And Other Chacoan Great Houses: The Healthiest And Wormiest Ancestral Puebloans, Karl Reinhard

Karl Reinhard Publications

Two fields of paleopathological investigation originated in the Southwest. Archaeoparasitology is the study of ancient parasite infection (Reinhard 1990, 1992b). It includes comparisons between time periods of single societies as well as comparisons of parasitism between different, contemporaneous cultures. For example, Fry (1980) compared Fremont and Anasazi parasitism, and also Archaic hunter-gatherer and ancestral Pueblo parasitism. All of these studies fall into the definition of archaeoparasitology.

By contrast, pathoecology is the reconstruction of relationships among behavior, environment, and disease organisms in the development of illness (Martinson et al. 2003; ReinhardandBuikstra2003; Reinhardet al. 2003; Santoro et al. 2003).1his field developed from …

Cranial Deformation As The Cause Of Death For A Child From The Chillon River Valley, Peru, Shelia M.F. Medoncade Souza, Karl J. Reinhard, Andrea Lessa

Karl Reinhard Publications

Two small mummy bundles, found in a tomb at the Chillon River Valley, Lima Plains, Peru exist in the collections of the Museu Nacional, Rio de Janeiro, Brazil. They were donated to the collections at the beginning of the 20th century. A multidisciplinary team is now curating and studying them. CT scans confirmed both skeletons were of individuals less than one year old at death. One of the bundles is intact and will be preserved and displayed. The other one was partly decomposed and the authors received permission to unwrap it to analyze the bones in details. Mites and pollen …

A Child And His Fate: Tuberculosis, Perimortem Trauma And Mummification, Sheila M. M.De Souza, Karl J. Reinhard, Bernardo Tessarollo, Jose Fernando Cardona Zannier, Adauto Araujo

Karl Reinhard Publications

A male child, sitting, 7 years, circumferential deformation, skin marked by coiled fibers, nostril plugs, consistent with Aymara practices was CT scanned. Puppae in the skin suggest exposition of the body previous to the funeral. Dark brown color at the skin suggest blood perfusion. A broken area at the right frontal with the skin partially inside is suggestive of perimorten trauma. There were no bone debris inside the skull and the CT images show two confluent fractures defined by radiating lines extending beyond the missing bone surface. The right eyeball is projected out, the tongue is outside the mouth, the …

Pathoecology And The Future Of Coprolite Studies In Bioarchaeology, Karl J. Reinhard, Vaughn M. Bryant Jr.

Karl Reinhard Publications

Human coprolites currently provide an expanding array of information about the diet, health, and ecology of prehistoric people in the Southwest, but for many years coprolites were not recognized or preserved, or they were not considered important and thus were not saved (Bryant and Dean 2006). With the expansion of archaeological field work during the last half of the twentieth century archaeologists have increasingly explored the "complete" potentials of sites, including the collection and analysis of geomorphologic, botanical, and faunal data. In some ideal habitats (e.g., very dry or frozen) this includes exploring the scientific potential of human coprolite studies. …

Pathoecology Of Two Ancestral Pueblo Villages, Karl Reinhard

Karl Reinhard Publications

Pathoecology is the study of the biotic, abiotic, and cultural environments of disease (Martinson et al. 2003). A parasitic infection is the result of the pathoecological interaction of host behavior, parasite life cycle, the environment in which both life forms live, the nutritional status of the host, and host physiological responses to all of these factors. Parasites contribute to anemia in many ways. Some, such as hookworm, actually consume blood and cause iron loss through their activities. For other parasites, symptoms such as profuse diarrhea reduce intestinal absorption of nutrients. Others, such as certain fish tapeworms, actually compete for absorption …

Paleoparasitology: Perspectives With New Techniques, Adauto Araújo, Karl Reinhard, Otilio M. Bastos, Ligia C. Costa, Claude Pirmez, Alena Iñighez, Ana Carolina Vicente, Carlos M. Morel, Luiz Fernando Ferreira

Karl Reinhard Publications

Paleoparasitology is the study of parasites found in archaeological material. The development of this field of research began with histological identification of helminth eggs in mummy tissues, analysis of coprolites, and recently through molecular biology. An approach to the history of paleoparasitology is reviewed in this paper, with special reference to the studies of ancient DNA identified in archaeological material.

Beyond Liberals And Conservatives To Political Genotypes And Phenotypes, John R. Alford, Carolyn L. Funk, John R. Hibbing

Department of Political Science: Faculty Publications

In the past, most political scientists have been oblivious to the growing empirical evidence challenging environmental determinism. Professor Charney, apparently as a result of the fact that genes and the environment interact in a complex fashion, advocates that this passive unawareness be replaced by active denial. Science, however, does not advance by avoiding important relationships merely because they are complicated and, fortunately, science is not heeding Charney’s ideologically-based fears. Molecular geneticists, often working in tandem with political scientists, are quickly moving beyond twin studies to identify the specific suites of genes and biological systems that predict variation in core political …

The New Empirical Biopolitics, John R. Alford, John R. Hibbing

Department of Political Science: Faculty Publications

Political science traditionally has either ignored biology in favor of purely environmental explanations for political phenomena or merely ruminated about the likely role of biology, leaving data-based research on biopolitics in dangerously short supply. Currently, attention to the apparent genetic basis for political and social orientations holds the greatest promise of advancing empirical biopolitics. Thus, in this essay, we orient behavior genetics research in the larger framework of biology and politics, confront its normative implications, describe the techniques involved, assess the strengths and weaknesses of commonly employed data and procedures, and describe the next steps in this research stream. Because …

Geographic Patterns Of At-Risk Species, Curtis H. Flather, Michael S. Knowles, Jason Mcnees

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

This technical document supports the Forest Service’s requirement to assess the status of renewable natural resources as mandated by the Forest and Rangeland Renewable Resources Planning Act of 1974. It updates past reports on the trends and geographic patterns of species formally listed as threatened or endangered under the Endangered Species Act of 1973. We compare the geographic occupancy of threatened and endangered species at the county-level against the geographic occupancy of a broader set of species thought to be at risk of extinction. This is done to determine if new areas where species rarity may be concentrated emerge. Here …

Mammalian Visitation To Candidate Feral Swine Attractants, Tyler A. Campbell, David B. Long

United States Department of Agriculture Wildlife Services: Staff Publications

Few data exist regarding suitable feral swine (Sus scrofa) attractants in the United States. We compared species-specific visitation and contact rates of mammals to 11 candidate feral swine attractants at scent stations using motion-sensing digital photography to identify promising attractants. We found feral swine had greater visitation rates to apple and strawberry stations than to control stations. We recommend managers consider using strawberry attractants for feral swine-specific applications. If, however, a general feral swine attractant is needed, then apple, berry, or caramel attractants may perform well.

Avoidance Of Hydrolyzed Casein By Mice, Kristin L. Field, Bruce A. Kimball, Julie A. Mennella, Gary K. Beauchamp, Alexander A. Bachmanov

United States Department of Agriculture Wildlife Services: Staff Publications

When casein, a milk protein, is hydrolyzed, it renders human foods that contain it (e.g., hypoallergenic infant formula, cheeses) distasteful to many people. This rejection of hydrolyzed casein (HC)-containing foods has recently been found to also occur in a non-human species (deer, Odocoileus spp.). Identifying other animals that avoid HC would facilitate understanding how and why HC-containing food is often rejected. This study determined whether HC-containing food is avoided by Mus musculus and whether consumption patterns were sensitive to testing conditions, specifically food form (powder, pellet or dough) and food access (ad libitum or 1.5 h/day following 6 h …

Breeding Red-Winged Blackbird Response To Conspecific Models Placed In Pre-Copulatory Position: Implications For Reproductive Control, Laurel L. Moulton, George M. Linz, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

Sunflower producers in the northern Great Plains are annually plagued by feeding flocks of blackbirds, especially red-winged blackbirds (RWBL). Increased sunflower production and concomitant human-blackbird conflicts have prompted sunflower producers to demand that management strategies be developed to reduce the annual crop losses estimated at ≥ $10 million (Linz et al. 1996). Past techniques aimed at reducing blackbird damage have had varying degrees of success and the annual loss of sunflower remains the same (Peer et al. 2002). Thus, there is a need for new innovative approaches to managing blackbird damage.

One approach is to find non-lethal species-specific methods of …

Evaluation Of Stop-Level Vs. Route-Level Breeding Bird Survey Counts For Modeling The Influence Of Land Use And Climate On Breeding Blackbird Abundance In North Dakota, Michelle L. Petersen, George M. Linz, Greg Forcey, Wayne Thogmartin, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

The Red-winged Blackbird (Agelaius phoeniceus), Yellow-headed Blackbird (Xanthocephalus xanthocephalus), and Common Grackle (Quiscalus quiscula) are the three most abundant blackbird species (Icteridae) found in North Dakota and comprise almost 10% of its avian population (Stewart and Kantrud 1972). Blackbird abundance combined with their food habitats make them significant agricultural pests on sunflower. Cost estimates for blackbird damage to sunflower in the North Dakota are likely over $10 million dollars annually (Kleingartner, pers. comm). Because of this economic impact blackbirds have on agriculture, it is important to understand land use and climatic factors influencing blackbird …

Development Of Polymorphic Microsatellite Loci For The Common Vampire Bat, Desmodus Rotundus (Chiroptera: Phylostomidae), Antoinette J. Piaggio, John J. Johnston, Susan L. Perkins

United States Department of Agriculture Wildlife Services: Staff Publications

The common vampire bat (Desmodus rotundus) is one of three haematophagous species of bats and the only species in this genus. These New World bats prey on mammals and create significant economic impacts through transmission of rabies in areas where livestock are prevalent. Furthermore, in some portions of their range, it is not uncommon for them to prey upon humans. It is critical to the management of this species and for understanding the spread of bat rabies that detailed studies of D. rotundus population structure be conducted. To further such studies, we have characterized 12 microsatellite loci for …
