Prediction Of Ground Water Vulnerability Using An Integrated Gis-Based Neuro-Fuzzy Techniques

Journal of Spatial Hydrology

There is a need to develop new modeling techniques that assess ground water vulnerability with less expensive data and which are robust when data are uncertain and incomplete. Incorporation of Geographic Information Systems (GIS) with a modeling approach that is robust has the potential for creating a successful modeling tool. The specific objective of this study was to develop a model using Neuro-fuzzy techniques in a GIS to predict ground water vulnerability. The Neuro-fuzzy model was developed in JAVA using four plausible parameters deemed critical in transporting contaminants in and through the soil profile. These parameters include soil hydrologic group, …

Multiple Domains Of The Co-Chaperone Hop Are Important For Hsp70 Binding, Gregory M. Nelson, Patricia E. Carrigan, Patricia J. Roberts, Jha'nae Stoffer, Daniel L. Riggs, David F. Smith

Faculty Publications

The Hop/Sti1 co-chaperone binds to both Hsp70 and Hsp90. Biochemical and co-crystallographic studies have suggested that the EEVD-containing C terminus of Hsp70 or Hsp90 binds specifically to one of the Hop tetratricopeptide repeat domains, TPR1 or TPR2a, respectively. Mutational analyses of Hsp70 and Hop were undertaken to better characterize interactions between the C terminus of Hsp70 and Hop domains. Surprisingly, truncation of EEVD plus as many as 34 additional amino acids from the Hsp70 C terminus did not reduce the ability of Hsp70 mutants to co-immunoprecipitate with Hop, although further truncation eliminated Hop binding. Hop point mutations targeting a carboxylate …

Linkage Of Arcview Gis With The Rzwqm

Journal of Spatial Hydrology

The Root Zone Water Quality Model (RZWQM) is a one-dimensional, lumped field-scale model. It can simulate major physical, chemical, and biological processes in an agricultural crop production system. While its reliability has been verified by several researchers, because of its lumped structure RZWQM could not account for the soil heterogeneity and the associated nonuniformity of management practices across the field. Neglecting the variability may result in misleading simulation results. On the other hand, the variability can be accurately characterized by using a geographic information system (GIS), especially ArcView GIS, the most widely used desktop mapping and geographic analysis system. Linked …

Contributions Of Family Leisure To Family Functioning Among Transracial Adoptive Families, Ramon B. Zabriskie, Patti Freeman

Faculty Publications

The purpose of this study was to examine family leisure behavior among intact families with transracial adoptive children and make comparisons to a broad sample of families with only biological children. The sample consisted of 197 adoptive families. Data were analyzed from a parent, youth, and family perspective. The Family Leisure Activity Profile (FLAP) was used to determine family leisure involvement. FACES II was used to measure family functioning. Findings indicated that measures of family cohesion, family adaptability, and family functioning were higher among the adoptive family sample. Core, balance, and total family leisure involvement were also higher among the …

The Influences Of Family Leisure Patterns On Perceptions Of Family Functioning*, Ramon B. Zabriskie, Bryan P. Mccormick

Faculty Publications

This study conducted a preliminary test of a model of family leisure functioning by examining the relationship of core and balance family leisure patterns to family cohesion and adaptability. We hypothesized that core family leisure patterns address family needs for stability, facilitate the development of cohesive relationships, and are related to perceptions of family cohesion, whereas balance family leisure patterns address family needs for change, facilitate the development of adaptive skills, and are related to perceptions of family adaptability. Findings from 2 multiple regression analyses provided preliminary support for the model. Conclusions and implications are discussed.

Re-Immigration To Denmark: The Challenge Of Reintegration, Jette Mackintosh

The Bridge

Over the years, I have known a lot of happy and contented immigrants to the United States, and this made me wonder what motivated return migration. It was a completely uncharted field, so it was an exciting challenge when, in 1996, I was asked to give a paper on the subject at an international conference in Gothenburg. It has since developed into a full-scale research project and a book.

American Fatherhood Types: The Good, The Bad, And The Uninterested, Loren Marks, Rob Palkovitz

Faculty Publications

This paper presents four contemporary types of American manhood: (a) the new, involved father, (b) the good provider, (c) the deadbeat dad, and (d) the paternity-free man. These four types are compared, contrasted, and contextualized with related data from the classic Middletown studies of the 1920s and 1930s. The significance and implications of the trend toward paternity-free manhood are discussed, and directions for future research are suggested.

Self-Aligned Mechanical Attachment Of Carbon Nanotubes To Silicon Dioxide Structures By Selective Silicon Dioxide Chemical-Vapor Deposition, Jed D. Whittaker, Ghaleb A. Husseini, Matthew A. Linford, Robert C. Davis, Markus Brink

Faculty Publications

A self-aligned thin-film deposition technique was developed to mechanically attach carbon nanotubes to surfaces for the fabrication of structurally robust nanotube-based nanomechanical devices. Single-walled carbon nanotubes were grown by thermal chemical-vapor deposition (CVD) across 150-nm-wide SiO2 trenches. The nanotubes were mechanically attached to the trench tops by selective silicon tetraacetate-based SiO2 CVD. No film was deposited on the nanotubes where they were suspended across the trenches.

Attributes Associated With Probability Of Infestation By The Piñon Ips, Ips Confusus (Coleoptera: Scolytidae), In Piñon Pine, Pinus Edulis, José F. Negrón, Jill L. Wilson

Western North American Naturalist

We examined attributes of piñon pine (Pinus edulis) associated with the probability of infestation by piñon ips (Ips confuses) in an outbreak in the Coconino National Forest, Arizona. We used data collected from 87 plots, 59 infested and 28 uninfested, and a logistic regression approach to estimate the probability of infestation based on plot and tree-level attributes. Piñon pine stand density index was a good predictor of the likelihood of infestation by piñon ips at the plot level, and a cross-validation analysis confirmed that the model correctly classified 82% of the cases. Diameter at root collar …

Soil Properties Associated With Vegetation Patches In A Pinus Ponderosa–Bunchgrass Mosaic, Becky K. Kerns, Margaret M. Moore, Michael E. Timpson, Stephen C. Hart

Western North American Naturalist

Since Euro-American settlement, fire exclusion and other factors have dramatically altered interior western coniferous forests. Once open and parklike, present-day structure in many southwestern Pinus ponderosa forests consists of dense stands of young, small-diameter trees, with small patches of larger, old trees, and relict open bunchgrass areas. Our objectives were to assess differences in soil properties associated with these different vegetation patches. We examined soil morphological characteristics, pH, organic C concentration, total N concentration, C:N ratio, and phytolith concentration from profiles within 6 transects (18 soil pedons) crossing patches of dense stands of small diameter trees, patches of old-growth trees, …

Habitat Features And Predictive Habitat Modeling For The Colorado Chipmunk In Southern New Mexico, Marina Rivieccio, Bruce C. Thompson, William R. Gould, Kenneth G. Boykin

Western North American Naturalist

Two subspecies of Colorado chipmunk (state threatened and federal species of concern) occur in southern New MeXico: Tamias quadrivittatus australis in the Organ Mountains and T. q. oscuraensis in the Oscura Mountains. We developed a GIS model of potentially suitable habitat based on vegetation and elevation features, evaluated site classifications of the GIS model, and determined vegetation and terrain features associated with chipmunk occurrence. We compared GIS model classifications with actual vegetation and elevation features measured at 37 sites. At 60 sites we measured 18 habitat variables regarding slope, aspect, tree species, shrub species, and ground cover. We used logistic …

Population Structure And Paternity In An American Black Bear (Ursus Americanus) Population Using Microsatellite Dna, Elizabeth A. Sinclair, Hal L. Black, Keith A. Crandall

Western North American Naturalist

We report genetic microsatellite data from analysis of 71 American black bears (Ursus americanus) from the East Tavaputs Plateau in eastern Utah. Heterozygosity was 52.9%, which is lower than other mainland North American populations and possibly reflects low recruitment into the study area. We used a combination of known pedigrees (mother/cubs), relatedness estimates, and paternity estimation using CERVUS to infer single and possible multiple paternity within litters, breeding by pairs over consecutive years, and the possibility of a single male successfully breeding with multiple females in a single year. Estimates of inbreeding effective population size indicate the East …

Arbuscular Mycorrhizae In Thermal-Influenced Soils In Yellowstone National Park, Rebecca A. Bunn, Catherine A. Zabinski

Western North American Naturalist

Mycorrhizae are common plant-fungal symbioses occurring in most land plants. Despite their ubiquity, little is known about the distribution of arbuscular mycorrhizae (AM) in extreme environments. We surveyed for the presence of AM in thermal sites in Yellowstone National Park (YNP) where soils are characterized by extreme pHs, elevated temperatures, and toxic element concentrations. Plants at 5 sites, growing in soils with rooting-zone temperatures up to 48°C and soil pH values as low as 3.4, were mycorrhizal (colonization levels from 4% to 34%). Soils from a sparsely vegetated thermal area and an adjacent, continuously vegetated transition area differed significantly in …

Western Scrub-Jay Breeding Biology In Central Colorado, Kerri Vierling, Barbara L. Winternitz

Western North American Naturalist

The breeding ecology of the Western Scrub-Jay (Aphelocoma californica) in the midwestern United States is relatively unknown compared with Aphelocoma species in other geographic regions. We examined Western Scrub-Jay breeding biology in Colorado between 1970 and 1992. Incubation was initiated in early April and lasted 16 days, while the nestling stage lasted approximately 17-18 days. Clutch size averaged 4.0 eggs per nest, reproductive success was 25%, and productivity averaged 0.66 fledglings per nest. The low reproductive success and productivity measures may be due to high predator densities in the surrounding suburban landscape. Western Scrub-Jays preferred nesting in eastern …

Beaver Herbivory Of Willow Under Two Flow Regimes: A Comparative Study On The Green And Yampa Rivers, Stewart W. Breck, Kenneth R. Wilson, Douglas C. Andersen

Western North American Naturalist

The effect of flow regulation on plant-herbivore ecology has received very little attention, despite the fact that flow regulation can alter both plant and animal abundance and environmental factors that mediate interactions between them. To determine how regulated flows have impacted beaver (Castor Canadensis) and sandbar willow (Salix exigua) ecology, we first quantified the abundance and mapped the spatial distribution of sandbar willow on alluvial sections of the flow-regulated Green River and free-flowing Yampa River in northwestern Colorado. We then established 16 and 15 plots (1 m x 2.7 m) in patches of willow on the …

Nesting And Brood-Rearing Characteristics Of Chukars In West Central Idaho, Andrew J. Lindbloom, Kerry P. Reese, Peter Zager

Western North American Naturalist

We analyzed attributes from 23 nests (10 renests) and 46 brood locations of radio-marked Chukars (Alectoris chukar) in the lower Salmon River canyon of west central Idaho in 1995 and 1996. Nesting effort was 100%, apparent nest success was 45%, and estimated time from destruction or abandonment of a nest to initiation of laying a subsequent nest averaged 13 ± 5 days s_x. Average clutch size for 1st nests (14.5 ± 1.0) was greater (P = 0.017) than renests (10.4 ± 1.1). Cover types used by nesting Chukars included grass/forb (48% of nests), rock (43%), …
