An Artificial Intelligence Approach To International Market Screening Dss, Kelly E. Fish

Journal of International Technology and Information Management

This paper applies artificial intelligence (AI) computing, Kohonan Self-Organizing Maps (SOMs), to the problem of international market selection (IMS). Broadly speaking, IMS can be summarized to consist of three stages a) screening stage, b) identification stage and, c) selection stage. The screening stage often employs some type of grouping technique so that firms can begin to view the potential markets in terms of similarities and differences over variables of interest. The underlying purpose is to screen out or eliminate markets that do not meet certain criteria established by the firm. Statistical techniques such as cluster analysis, discriminant analysis or factor …

Access To Computer Technologies At Home Improves Wages In The Marketplace, Pankaj Kumar Maskara, Rajesh Aggarwal, Rajesh Maskara

Journal of International Technology and Information Management

This study suggests that having access to a computer and the Internet at home leads to better wages. We normally have the idea that people with higher wages have computers and Internet access at home. But with declining prices of home PCs and the increasing importance of Internet, this no longer seems to be the case. The new owners of PC today are considerably poorer and less educated than in the past. People with access to a PC and Internet at home appear to earn 8.6% more than their counterpart. This result seems to suggest that University policies requiring students …

Interrelationships Among Language Skills, Externalizing Behavior, And Academic Fluency And Their Impact On The Academic Skills Of Students With Ed, J. Ron Nelson, Gregory J. Benner, Stern Neill, Scott A. Stage

Department of Special Education and Communication Disorders: Faculty Publications

There is growing interest in understanding the factors that influence the academic achievement of students with emotional disturbance (ED). Structural equation modeling was used to test the interrelationships among language skills, externalizing behavior, and academic fluency and their impact on the academic skills of students with ED. Results showed that language skills exerted a significant proximal effect and distal effect on academic skills. The effect of language skills was mediated through academic fluency (path coefficient = .389) but also had a proximal effect on academic skills (path coefficient = .359). However, externalizing behavior failed to have a statistically significant effect …

Coordinative Organization Of Lingual Propulsion During The Normal Adult Swallow, Erin M. Wilson, Jordan R. Green

Department of Special Education and Communication Disorders: Faculty Publications

Lingual propulsion during swallowing is characterized by the sequential elevation of the anterior, middle, and dorsal regions of the tongue. Although lingual discoordination underlies many swallowing disorders, the coordinative organization of lingual propulsion during the typical and disordered swallow is poorly understood. The purpose of this investigation was to quantitatively describe the coordinative organization of lingual propulsion during the normal adult swallow. Tongue movement data were obtained from the X-Ray Microbeam Database at the University of Wisconsin. Movement of four pellets placed on specific tongue regions were tracked in 36 healthy adult participants while they swallowed 10 cc of water …

A Longitudinal Study Of The Effects Of Early Abuse On Later Victimization Among High-Risk Adolescents, Kimberly A. Tyler, Katherine A. Johnson

Department of Sociology: Faculty Publications

Although previous research on adolescents finds a link between early abuse and later victimization, the majority of this research is cross-sectional and based on samples of currently homeless adolescents. Therefore, factors that predict the likelihood of victimization have not been systematically examined. As such, the current study longitudinally examines the effects of early abuse and poor parenting on victimization via running away, delinquency, and early sexual onset among a sample of over 700 currently housed high-risk adolescents. Results revealed that having experienced sexual and physical abuse, as well as lower levels of parental monitoring and closeness, significantly predicted running away …

Negative Impact Of Noise On The Principal Component Analysis Of Nmr Data, Steven M. Halouska, Robert Powers

Department of Chemistry: Faculty Publications

Principal component analysis (PCA) is routinely applied to the study of NMR based metabolomic data. PCA is used to simplify the examination of complex metabolite mixtures obtained from biological samples that may be composed of hundreds or thousands of chemical components. PCA is primarily used to identify relative changes in the concentration of metabolites to identify trends or characteristics within the NMR data that permits discrimination between various samples that differ in their source or treatment. A common concern with PCA of NMR data is the potential over emphasis of small changes in high concentration metabolites that would over-shadow signifi …

Stability Of Warfarin Solutions For Drug–Protein Binding Measurements: Spectroscopic And Chromatographic Studies, Annette C. Moser, Charles A. Kingsbury, David S. Hage

Department of Chemistry: Faculty Publications

Warfarin is commonly used in drug–protein binding studies as a displacement marker for Sudlow site I on the protein human serum albumin (HSA). This study examined the stability of aqueous warfarin solutions prepared for such experiments. This was investigated using NMR spectroscopy and affinity chromatography. It was found by 1H NMR that warfarin underwent a slow first-order conversion in aqueous solution. The rate of this reaction increased with temperature, giving rate constants at pH 7.4 of 0.0086 h⁻¹ at 25 °C and 0.041 h⁻¹ at 37 °C. It was concluded from further 1H and 13C NMR studies, along …

Potential Added Value Of Psychological Capital In Predicting Work Attitudes, Milan Larson, Fred Luthans

Department of Management: Faculty Publications

Meeting the challenge of effectively managing human resources requires new thinking and approaches. To extend the traditional perspective of economic capital, increasing recognition is being given to human capital and more recently social capital, this article proposes and empirically tests the potential added value that psychological capital may have for employee attitudes of satisfaction and commitment. After first providing the background and theory of PsyCap, this article reports a study of manufacturing employees (N = 74) that found a significant relationship between PsyCap and job satisfaction (r=.373) and organization commitment (r=.313). Importantly, the employees’ PsyCap had a significant added impact …

Privies And Parasites: The Archaeology Of Health Conditions In Albany, New York, Charles L. Fisher, Karl Reinhard, Matthew Kirk, Justin Divirgilo

Karl Reinhard Publications

Large numbers of parasites were identified in archaeological samples collected from privies and other features in excavations in Albany, New York. This information provides the largest database available for the study of parasite infections in historical period American cities. The greatest numbers of parasites were in contexts related to the expansion of the city in the late-18th century. Parasites remained, but their quantities decreased in the 19th century during another period of rapid population growth. The city was able to control parasite infection during this period through several means, including new techniques of privy construction, new water supply systems, and …

Sl1 Rna Gene Recovery From Enterobius Vermicularis Ancient Dna In Pre-Columbian Human Coprolites, Alena M. Iñiguez, Karl Reinhard, Marcelo Luiz Carvalho Gonçalves, Luiz Fernando Ferreira, Adauto Araújo, Ana Carolina Paulo Vincente

Karl Reinhard Publications

Enterobius vermicularis, pinworm, is one of the most common helminths worldwide, infecting nearly a billion people at all socio-economic levels. In prehistoric populations the paleoparasitological findings show a pinworm homogeneous distribution among hunter-gatherers in North America, intensified with the advent of agriculture. This same increase also occurred in the transition from nomad hunter-gatherers to sedentary farmers in South America, although E. vermicularis infection encompasses only the ancient Andean peoples, with no record among the pre-Colombian populations in the South American lowlands. However, the outline of pinworm paleo epidemiology has been supported by microscopic finding of eggs recovered from coprolites. …

Paired-End Sequence Mapping Detects Extensive Genomic Rearrangement And Translocation During Divergence Of Francisella Tularensis Subsp. Tularensis And Francisella Tularensis Subsp. Holarctica Populations, Michael P. Dempsey, Joseph Nietfeldt, Jaques Ravel, Steven H. Hinrichs, Robert Crawford, Andrew K. Benson

Department of Food Science and Technology: Faculty Publications

Comparative genome hybridization of the Francisella tularensis subsp. tularensis and F. tularensis subsp. holarctica populations have shown that genome content is highly conserved, with relatively few genes in the F. tularensis subsp. tularensis genome being absent in other F. tularensis subspecies. To determine if organization of the genome differs between global populations of F. tularensis subsp. tularensis and F. tularensis subsp. holarctica, we have used paired-end sequence mapping (PESM) to identify regions of the genome where synteny is broken. The PESM approach compares the physical distances between paired-end sequencing reads of a library of a wild-type reference F. tularensis …

Developing And Extending Sustainable Agriculture: A New Social Contract, Michele Schoeneberger, Gary Bentrup, Charles A. Francis, Richard Straight

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

Conclusions

Based on the practical community applications of woody buffe rs and multifuncti onal areas that grew from the ini tial concepts ofecobelts. we are convinced that this type of initiative is a viable option in establishing a positive interface between different types of human activities. The challenge becomes more real every day, as cities expand and both city-edge subdivisions and acreages create ever more interfaces between people with different and often con!1icting activities and basic values. There is a need to provide some logical and acceptable boundary between these people and their different lifestyles. It is also desirable to …

All Parents Are To Blame (Except This One): Global Versus Specific Attitudes Related To Parental Responsibility Laws, Eve M. Brank, Stephanie A. Hays, Victoria Weisz

Department of Psychology: Faculty Publications

Increasing state legislation and media interest give the appearance of public support for parental responsibility laws; however, some national polls suggest otherwise. Based on disparate global and specific attitudes in other areas of the criminal justice literature, it was hypothesized that relatively weak global support for parental responsibility would be diminished even more if a specific juvenile was described. The current studies confirmed that participants were even less supportive of parental responsibility laws when a specific juvenile and his parents were described than they were when they answered questions about parents in general.

Multi-Species Patterns Of Avian Cholera Mortality In Nebraska’S Rainwater Basin, Julie A. Blanchong, Michael D. Samuel, Gene Mack

United States Geological Survey: Staff Publications

Nebraska’s Rainwater Basin (RWB) is a key spring migration area for millions of waterfowl and other avian species. Avian cholera has been endemic in the RWB since the 1970s and in some years tens of thousands of waterfowl have died from the disease. We evaluated patterns of avian cholera mortality in waterfowl species using the RWB during the last quarter of the 20th century. Mortality patterns changed between the years before (1976–1988) and coincident with (1989–1999) the dramatic increases in lesser snow goose abundance and mortality. Lesser snow geese (Chen caerulescens caerulescens) have commonly been associated with mortality …

United States Geological Survey: Staff Publications

Alpersite, Mg_0.58 Cu_0.37 Zn_0.02 Mn_0.02 Fe_0.01SO₄ •7H₂ O, a new mineral species with direct relevance to reactions in mine waste, occurs in a mineralogically zoned assemblage in sheltered areas at the abandoned Big Mike mine in central Nevada at a relative humidity of 65% and T = 4 °C. Blue alpersite, which is isostructural with melanterite (FeSO₄ •7H₂ O), is overlain by a light blue to white layer dominated by pickeringite, alunogen, and epsomite. X-ray diffraction data (MoKα radiation) from a single crystal of alpersite were refined in P2_{1 …}

Abundance And Distribution Of Selected Elements In Soils, Stream Sediments, And Selected Forage Plants From Desert Tortoise Habitats In The Mojave And Colorado Deserts, Usa, M. A. Chaffee, K. H. Berry

United States Geological Survey: Staff Publications

A baseline and background chemical survey was conducted in southeastern California, USA, to identify potential sources of toxicants in natural and anthropogenically-altered habitats of the threatened desert tortoise (Gopherus agassizii). Soil, stream sediment, and plant samples were collected from six tortoise habitat study areas in the Mojave and Colorado deserts and analysed for up to 66 different elements. The chemical analyses provided new information on the abundances and distributions of selected elements in this region. Soil, stream-sediment, and plant analyses showed distinct variations in bulk chemistries from locality to locality. Variations were, in general, consistent with the many …

A Method For Mapping Corn Using The Us Geological Survey 1992 National Land Cover Dataset, S. K. Maxwell, J. R. Nuckols, M. H. Ward

United States Geological Survey: Staff Publications

Long-term exposure to elevated nitrate levels in community drinking water supplies has been associated with an elevated risk of several cancers including non-Hodgkin’s lymphoma, colon cancer, and bladder cancer. To estimate human exposure to nitrate, specific crop type information is needed as fertilizer application rates vary widely by crop type. Corn requires the highest application of nitrogen fertilizer of crops grown in the Midwest US.We developed a method to refine the US Geological Survey National Land Cover Dataset (NLCD) (including map and original Landsat images) to distinguish corn from other crops. Overall average agreement between the resulting corn and other …

Seasonal And Spatial Patterns Of Metals At A Restored Copper Mine Site. I. Stream Copper And Zinc, Dustin G. Bambic, Charles N. Alpers, Peter G. Green, Eileen Fanelli, Wendy K. Silk

United States Geological Survey: Staff Publications

Seasonal and spatial variations in metal concentrations and pH were found in a stream at a restored copper mine site located near a massive sulfide deposit in the Foothill copper-zinc belt of the Sierra Nevada, California. At the mouth of the stream, copper concentrations increased and pH decreased with increased streamflow after the onset of winter rain and, unexpectedly, reached extreme values 1 or 2 months after peaks in the seasonal hydrographs. In contrast, aqueous zinc and sulfate concentrations were highest during low-flow periods. Spatial variation was assessed in 400 m of reach encompassing an acidic, metal-laden seep. At this …

Landscape Context Mediates Influence Of Local Food Abundance On Wetland Use By Wintering Shorebirds In An Agricultural Valley, Oriane W. Taft, Susan M. Haig

United States Geological Survey: Staff Publications

While it is widely understood that local abundance of benthic invertebrates can greatly influence the distribution and abundance of wetland birds, no studies have examined if wetland landscape context can mediate this relationship. We studied the influence of wetland food abundance and landscape context on use of agricultural wetlands by wintering dunlin (Calidris alpina) and killdeer (Charadrius vociferus) in the Willamette Valley of Oregon, USA, over two winters (1999–2000, 2000–2001) of differing rainfall and subsequent habitat distribution. We monitored bird use (frequency of occurrence and abundance) at a sample of wetlands differing in local food abundance …

The National Wildlife Refuge System, Robert P. Davison, Alessandra Falcucci, Luigi Maiorano, J. Michael Scott

United States Geological Survey: Staff Publications

The National Wildlife Refuge System (NWRS) has played a key role in conserving at-risk species from its beginnings in 1903 when President Theodore Roosevelt established apreserve to protect Pelican Island, in Florida, as a breeding ground for an imperiled population of brown pelicans (Pelecanus occidentalis) (Fischman 2003). Today, the Atlantic coast population of the brown pelican is no longer in need of protection under the Endangered Species Act (ESA) , but Pelican Island National Wildlife Refuge provides protection for nine threatened and endangered species.

Management of the refuge system has changed significantly since the presidency of Teddy Roosevelt, …

Environmental Contaminants In Fish And Their Associated Risk To Piscivorous Wildlife In The Yukon River Basin, Alaska, Jo Ellen Hinck, Christopher J. Schmitt, Kathy R. Echols, Tom W. May, Carl E. Orazio, Donald E. Tillitt

United States Geological Survey: Staff Publications

Organochlorine chemical residues and elemental contaminants were measured in northern pike (Esox lucius), longnose sucker (Catostomus catostomus), and burbot (Lota lota) from 10 sites in the Yukon River Basin (YRB) during 2002. Contaminant concentrations were compared to historical YRB data and to toxicity thresholds for fish and piscivorous wildlife from the scientific literature. A risk analysis was conducted to screen for potential hazards to piscivorous wildlife for contaminants that exceeded literature-based toxicity thresholds. Concentrations of total DDT (sum of p,p¢-homologs; 1.09–13.6 ng/g), total chlordane (0.67–7.5 ng/g), dieldrin (<0.16–0.6 ng/g), toxaphene (<11–34 ng/g), total PCBs (<20– 87 ng/g), TCDD-EQ (<1.7 pg/g), arsenic (0.03–1.95 lg/g), cadmium (<0.02–0.12 lg/g), copper (0.41–1.49 lg/g), and lead (<0.21–0.27 lg/g) did not exceed toxicity thresholds for growth and reproduction in YRB fish. Concentrations of mercury (0.08–0.65 lg/g), selenium (0.23–0.85 lg/g), and zinc (11–56 lg/g) exceeded toxicity thresholds in one or more samples and were included in the risk analysis for piscivorous wildlife. No effect hazard concentrations (NEHCs) and low effect hazard concentrations (LEHCs), derived from literaturebased toxicity reference values and avian and mammalian life history parameters, were calculated for mercury, selenium, and zinc. Mercury concentrations in YRB fish exceeded the NEHCs for all bird and small mammal models, which indicated that mercury concentrations in fish may represent a risk to piscivorous wildlife throughout the YRB. Low risk to piscivorous wildlife was associated with selenium and zinc concentrations in YRB fish. Selenium and zinc concentrations exceeded the NEHCs and LEHCs for only the small bird model. These results indicate that mercury should continue to be monitored and assessed in Alaskan fish and wildlife.

A Screening-Level Assessment Of Lead, Cadmium, And Zinc In Fish And Crayfish From Northeastern Oklahoma, Usa, Christopher J. Schmitt, William G. Brumbaugh, Gregory L. Linder, Jo Ellen Hinck

United States Geological Survey: Staff Publications
