Integrating Marriage Education Into Perinatal Education, Alan J. Hawkins, Tamara Gilliland, Glenda Christiaens, Jason S. Carroll

Faculty Publications

Couples making the transition to parenthood experience challenges that can threaten the quality and stability of their relationships and the health of family members. Currently, the educational infrastructure to support the delivery of couple-relationship education during the transition to parenthood is limited. Because new-parent couples interact with the health care system at many points during this transition time, an opportunity exists for strengthening couple relationships within the system to improve the well-being of adults and children. in this article, we propose a productive collaboration between marriage/couple educators and health care systems to integrate couple-relationship education into the standard of perinatal …

Investigating The Mechanism Of Acoustically Activated Uptake Of Drugs From Pluronic Micelles, Ghaleb A. Husseini, Christopher M. Runyan, William G. Pitt

Faculty Publications

Background

This paper examines the mechanism of ultrasonic enhanced drug delivery from Pluronic micelles. In previous publications by our group, fluorescently labeled Pluronic was shown to penetrate HL-60 cells with and without the action of ultrasound, while drug uptake was increased with the application of ultrasound.

Methods

In this study, the amount of uptake of two fluorescent probes, Lysosensor Green (a pH-sensitive probe) and Cell Tracker Orange CMTMR (a pH-independent probe), was measured in HL-60 and HeLa cells.

Results

The results of our experiments show that the increase in drug accumulation in the cells as a result of ultrasonication is …

Modification Of All-Hexadedral Finite Element Meshes By Dual Sheet Insertion And Extraction, Michael J. Borden

Theses and Dissertations

The development of algorithms that effectively modify all-hexahedral finite element mesh is currently an active area of research. Mesh modification can be used to improve mesh quality reduce the time required to mesh a model, and improve the finite element analysis results. However, general modification of all-hexahedral meshes has proven difficult because of the global effects of local modifications. This thesis explains the global constraints on modifying all-hexahedral meshes and then presents three mesh modification techniques that make it possible to do local modifications while accounting for the global effects. These techniques are sheet insertion, sheet extraction, and mesh cutting. …

Sorenson explains how this approach has helped people throughout the world better understand the Book of Mormon and how it will continue …

Women In The Book Of Mormon, Camille Williams

Journal of Book of Mormon Studies

Feminist readers, particularly, have argued that biblical writing is sexist because the majority of the text was written by men who seem to place little significance on the role of women. This observation has become a serious concern among some because it calls into question the nature of God: does this supposedly perfect being love men and women equally? This study delves into the text of the Book of Mormon and its female characters to suggest that women were not considered lower than men in Book of Mormon times; likewise, women are not considered lower than men in the Church …

Out Of The Dust: The Ossuary Of James, . . . Brother Of Jesus, Journal Of Book Of Mormon Studies

Journal of Book of Mormon Studies

A recently discovered ossuary with the inscription “James, son of Joseph, brother of Jesus” may be the resting place of the bones of James the Just, the brother of the Lord, from the New Testament. Analyses of the carving, the language, and the history of Israeli ossuaries are being undertaken in an attempt to unveil further information on this ossuary. If this ossuary is authentic and corresponds to the correct time period, it can be more strongly proposed that the bones that used to rest inside the ossuary did, in fact, belong to James, the brother of Jesus of Nazareth.

A Classification Of Aquatic Plant Communities Within The Nothern Rocky Mountains, John R. Pierce, Mark E. Jensen

Western North American Naturalist

A synecological study of aquatic macrophyte plant communities was conducted across northern Idaho and western Montana during the summers of 1997, 1998, and 1999. A total of 111 natural and man-made water bodies were sampled based on a stratification of environmental variables thought to influence plant species distribution (i.e., elevation, landform, geology, and water body size). Plant species foliar cover data were used to develop a hierarchical, floristic-based community type classification with TWINSPAN and DECORANA software. Six planmergent (conspicuous portion of vegetative plant body on the water surface) and 24 submergent (vegetative plant body found primarily underwater) community types were …

The Short Song Of Brewer's Sparrow: Individual And Geographic Variation In Southern Idaho, Terrell D. Rich

Western North American Naturalist

Brewer's Sparrows (Spizella breweri) have two song types—a "short" song that has 1 to 3 trill types and a "long" song that has 5 to 10 or more trill types. I describe the short song and examine patterns of individual and geographic song variation from 15 sites on the Snake River Plain in southern Idaho. Territorial males sang the short song regularly during the breeding season. Two-trill song types comprised 72.9% of all song types, with 3-trill types (18.8%) and 1-trill types (8.2%) less frequent. Over 90% of the males sang their song type(s) essentially without variation. Many …

Kanab Ambersnail And Other Terrestrial Snails In South Central Utah, Vicky J. Meretsky, Eric G. North, Lawrence E. Stevens

Western North American Naturalist

Surveys for succineid snails were conducted to improve genetic and geographical information for the endangered Kanab ambersnail (Oxyloma haydeni kanabensis Pilsbry) and related taxa within the Succineidae. Surveys were carried out in the Bureau of Land Management Kanab District, at the Grand Staircase Escalante National Monument, on 3 private holdings, and along Highways 89, 12, and 14, all in south central Utah. A population of Kanab ambersnails was known to exist in the region; other populations of Oxyloma were discovered in primarily seep-fed wetlands in Kanab Creek and in tributaries of and wetlands along the Virgin, Sevier, and Escalante …

Diet And Food-Niche Breadth Of Burrowing Owls (Athene Cunicularia) In The Imperial Valley, California, Melissa M. York, Daniel K. Rosenberg, Ken K. Sturm

Western North American Naturalist

Burrowing Owls (Athene cunicularia) occupy intensively managed agricultural areas within the Imperial Valley of California, where they occur at high densities relative to other areas in the state, and yet reproductive rates are often low. Understanding diet and food-niche breadth may lead to insights into factors contributing to their poor reproductive performance. We tested the relative contribution of sex, year, and season on diet composition and food-niche breadth from analyses of stomach contents of adult Burrowing Owls (n = 53). Orthoptera dominated the diet; it accounted for 58.9% of the total number of prey items in all …

Autumnal Migration Of Eared Grebes (Podiceps Nigricollis) Through Southwestern Wyoming: A Key To Assessing The Size Of The North American Population, Joseph R. Jehl Jr., Carl Johansson

Western North American Naturalist

In autumn the vast majority of the North American population of Eared Grebes (Podiceps nigricollis) congregates for several months at Great Salt Lake, Utah, and Mono Lake, California. Because the lakes are so large, it has not been possible to monitor grebe migration with sufficient accuracy to determine when peak numbers are reached. To clarify migration phenology, we analyzed data from 2 isolated wetland areas in southwestern Wyoming where grebes land en route between breeding areas in the interior and Great Salt Lake. Occasional birds, probably nonbreeders or failed breeders, begin moving southward as early as mid-June. Migration …

Orientation And Vertical Distribution Of Red-Naped Sapsucker (Sphyrapicus Nuchalis) Nest Cavities, Laurence R. Butcher, Scott A. Fleury, J. Michael Reed

Western North American Naturalist

It has been hypothesized (1) that the compass direction in which woodpeckers excavate breeding cavities depends on nest thermoregulatory needs, and (2) that when multiple cavities are placed in the same tree across years, each new cavity is placed above previous cavities. We tested these hypotheses for Red-naped Sapsuckers (Sphyrapicus nuchalis) in central Nevada and found some evidence that cavities are oriented for thermoregulatory advantage, but we rejected the hypothesis that active cavities are always the highest.

Arbuscular Mycorrhizae Of Mojave Desert Plants, Jonathan H. Titus, Priscilla J. Titus, Robert S. Nowak, Stanley D. Smith

Western North American Naturalist

Roots of 15 Mojave Desert plant species were assessed for arbuscular mycorrhizal (AM) colonization in spring and autumn 1999. Another 19 species were assessed in autumn only. Perennial species were AM colonized, whereas annual species contained very low levels of AM hyphae or were nonmycorrhizal. The nonnative tree Tamarix ramosissima was also nonmycorrhizal. Levels of hyphae changed over the season in 2 species, arbuscle levels increased in 1 species, and vesicles decreased in 7 species. Mycorrhizal inoculum potential (MIP) was assessed in the soils associated with spring-collected plants. All soils were found to contain MIP. MIP values were not correlated …

Sampling Effort And Vegetative Cover Estimates In Sagebrush Steppe, Richard S. Inouye

Western North American Naturalist

The goal of this study was to identify relationships between sampling effort, using a point frame, and the precision of estimates of vegetative cover in sagebrush steppe. Data for 208 point-frame samples were randomly drawn and 95% confidence intervals were identified for varying sample sizes of individual species and species groups. Confidence interval widths decreased rapidly as sample sizes increased from 1 to 50, and more slowly as sample sizes were increased further. For the more abundant species, sample sizes of fewer than 50 frames were sufficient to reduce the 95% confidence interval to less than one-half of average cover. …

Abundance And Condition Indices Of Coyotes On Hart Mountain National Antelope Refuge, Oregon, Mike R. Dunbar, Mark R. Giordano

Western North American Naturalist

U.S. Fish and Wildlife Service staff at Hart Mountain National Antelope Refuge (HMNAR), southeastern Oregon, documented high pronghorn (Antilocapra americana) fawn mortality, subsequent low fawn recruitment, and declining pronghorn numbers from 1996 to 1999. Coyote (Canis latrans) predation was the primary cause, accounting for 60–85% of fawn mortalities each year, and fawns were not physiologically predisposed to predation. Therefore, we investigated certain coyote population parameters (age structure, survival, density, physiology) to evaluate how or if these factors influence coyote predation rates on pronghorn fawns. We captured 11 coyotes (5 male and 6 female) in December 1998. …

Genetic Differentiation Of Rare And Common Varieties Of Eriogonum Shockleyi (Polygonaceae) In Idaho Using Issr Variability, James F. Smith, Terry A. Bateman

Western North American Naturalist

Idaho populations of Eriogonum shockleyi are divided taxonomically into 2 varieties: E. shockleyi var. packardae, which is endemic to Idaho, and the typical variety, which is widespread in the western United States. Recent morphological investigations of E. shockleyi in Idaho have identified potentially reliable morphological characters for field identification of the subspecific taxa. This paper investigates the genetic basis for the separation of the 2 varieties of E. shockleyi using inter simple-sequence repeats (ISSR) markers. Although we found some morphological differences between the populations that correlated with the 2 varieties, we identified no molecular markers in this study to …

Simple Spatially Distributed Model Of The Global Carbon Cycle And Its Dynamic Properties, Yuri Svirezhev

International Congress on Environmental Modelling and Software

A specially simplified spatially distributed model of the Global Carbon Cycle (GCC) is presentedthat is allowed to get a general solution and to study its basic dynamic properties (like spectral portrait,composition and decomposition of solutions, etc.). Assuming that the productivity depends linearly onconcentration of carbon in the atmosphere, the problem is reduced to a standard linear one. For calibrationthe Bazilevich data containing information on plant productivity, living biomass and soil organic matter ofdifferent biomes is used. Calculating the matrix eigenvalues of the basic linear problem we get its spectralportrait. The characteristic times change sufficiently smoothly from several years to several …

Indirect Effects In Ecosystems: A Review Of Recent Modelling Studies And A Methodological Framework For Comparative Theoretical Analysis, V. Krivtsov

International Congress on Environmental Modelling and Software

Indirect interrelations between ecosystem processes are often realised after a considerable time lag,and, therefore, are easily overlooked. The understanding of these relationships, however, is indispensable forsustainable development and ecomanagement. Investigation of mechanisms underpinning complex indirectdelayed relationships is greatly aided by advanced mathematical techniques, including correlation, multipleregression and factor analysis, simulation modelling, etc. This paper provides a brief review of the recentrelevant studies. These techniques may be especially useful if used in concert on a range of ecosystems, thusintegrating the information obtained in a comparative theoretical ecosystem analysis (CTEA). Amethodological framework for CTEA is given and possible implications discussed.

A Model For The Trophic Food Web Of The Gulf Of Trieste, G. Cossarini, Cosimo Solidoro, A. Crise

International Congress on Environmental Modelling and Software

The Gulf of Trieste is located in the northernmost part of the Adriatic Sea. It exhibits high variable hydrodynamical and trophic conditions, due to the interactions among the wind regime, characterised by impulsive strong wind events (Bora), the fresh water –nutrient rich- run off, especially from Isonzo river, the interaction with the general circulation of North Adriatic Sea, the seasonal heating and cooling of water and alternation of mixing and stratification of water column. Gulf is also characterised by occurrence of anomaly events as mucilagine. Despite the high inter-annual biological variability, it is possible to recognise the seasonal succession of …

Modelling Of Pop Environmental Persistence And Long Range Transport By Qsar And Chemometric Approaches, Paola Gramatica, Ester Papa, Stefano Pozzi

International Congress on Environmental Modelling and Software

The Long Range Transport (LRT) potential of chemicals is due to the combination of theirpersistence in the environment and their inherent tendency towards mobility, and is an undesirableproperty of POPs (Persistent Organic Pollutants). Finding the best combination of chemical properties tominimize LRT is a multicriteria problem that can be approached by MultiCriteria Decision-Making(MCDM) techniques. Utility functions have been applied to two proposed indexes, the “globalpersistence index” and the “mobility index”, allowing a ranking of the studied chemicals according totheir LRT potential. The “global persistence index” was obtained by linear combination, by PrincipalComponent Analysis of the half-life data in various environmental …

Ecological And Economic Modelling In Agricultural Land Use Scenarios, Bernd Münier, J. S. Schou, K. Birr-Pedersen

International Congress on Environmental Modelling and Software

Agricultural production and its associated land use comprise the most important key factor regarding biodiversity and environmental impact within the wider countryside in Denmark. Currently, a number of land use changes are implemented in environmental action plans, such as afforestation, restoring wetlands and protection of drinking water catchments. Growing attention is put on the potential of GIS (Geographical Information System) as spatial decision support tools in local and regional environmental impact assessment, planning and implementation of governmental policies at local level. The work presented is part of a multidisciplinary research project, addressing the consequences of changes in agricultural production with …

Exergy And Information Indices: A Comparison For Use In Structurally Dynamic Models, Brian D. Fath

International Congress on Environmental Modelling and Software

Ecosystems are open, dynamic systems changing both their structure and their function over time. A model, which is an abstraction of the system manifest at the time of its construction, can project future dynamics so long as the fundamental structure of the system does not change. A primary modelling challenge arises when the system structure changes, i.e., internal reorganization, as a result of external perturbation. Ideally, one could include algorithms in the model to anticipate such changes, but that would entail knowing a great deal more about the system and disturbances to it than is possible. Other methods to anticipate, …

Ideas For Assessing The Sustainability Potential Of Human- Environmental Auxiliary Systems - The Case Of Municipal Solid Waste Landfills -, D. J. Lang, Claudia R. Binder, B. Stäubli, Roland W. Scholz

International Congress on Environmental Modelling and Software

Although sustainability is a widely accepted guiding idea for the development of our planet, only a few concepts exist on how to specify this idea in the context of human-environmental systems. We understand sustainability as a combination of system limit management with ethical allegiances. Uncertainties given by large timeframes and vague definitions present a major problem when assessing if an object or circumstance is sustainable or not. However, a sound standing assessment is indispensable if sustainability is to be more than a buzzword. In this paper, we present a systemic method for assessing the sustainability potential of anthropogenic systems. This …

Potential Impact Of Global Warming On Tropical Tuna Habitat, Harilaos Loukos, Patrick Monfray, Laurent Bopp

International Congress on Environmental Modelling and Software

Recent studies suggest a reduction of primary production in the tropical oceans due to changes in oceanic circulation under global warming conditions caused by increasing atmospheric CO2 concentration. This might affect the productivity of higher trophic levels with potential consequences on marine resources such as tropical tuna. Here we combine the projections of up-to-date climate and ocean biogeochemical models with recent concepts of representation of fish habitat based on prey abundance and ambient temperature to gain some insight on the impact of climate change on skipjack tuna, the specie that dominates present day catches. For a 2xCO2 world, our results …
