Effects Of Cohabitation On Engaged Adult Relationships, Matthew W. Chingren Jan 2003

Effects Of Cohabitation On Engaged Adult Relationships, Matthew W. Chingren

Presidential Scholars Theses (1990 – 2006)

Low premarital intimacy and less-than-realistic marital expectations have been shown to successfully predict lower marital satisfaction and success. This study used an independent groups design to investigate the effect of cohabitation on intimacy and marital expectations among engaged adult individuals. Group I (n=30) consisted of engaged individuals cohabiting with their fiances and Group II (n=82) included engaged individuals not cohabiting. Participants were obtained through a convenience sample. All participants provided demographic data and completed the Personal Assessment of Intimacy in Relationships (PAIR) and the Marriage Expectations Scale (MES). Previously married participants were excluded from MES analysis due to the nature …

Restoration And Monitoring Of The River Otter Population In Iowa, J. A. Pitt, W. R. Clark, R. D. Andrews, K. P. Schlarbaum, D. D. Hoffman, S. W. Pitt Jan 2003

Restoration And Monitoring Of The River Otter Population In Iowa, J. A. Pitt, W. R. Clark, R. D. Andrews, K. P. Schlarbaum, D. D. Hoffman, S. W. Pitt

Journal of the Iowa Academy of Science: JIAS

Northern river otters (Lontra canadensis) were widespread in North America at the time of European settlement. However, river otters were extirpated from most of Iowa in the early 1900s due to habitat degradation and unregulated harvest. In 1985, the Iowa Department of Natural Resources began an effort to restore the river otter population throughout the state, including a pilot study of survival to determine if establishment was feasible. Annual survival was estimated to be 86% during the pilot study. River otters dispersed an average of about 11 km from the point of release and exhibited habitat use typical for the …

Occurrence Of Ovotestes And Plasma Vitellogenin In Feral Male Fathead Minnows From Lagoons Of Municipal Wastewater Treatment Facilities In Central Iowa, Robert B. Bringolf, Robert C. Summerfelt Jan 2003

Occurrence Of Ovotestes And Plasma Vitellogenin In Feral Male Fathead Minnows From Lagoons Of Municipal Wastewater Treatment Facilities In Central Iowa, Robert B. Bringolf, Robert C. Summerfelt

Journal of the Iowa Academy of Science: JIAS

Since the early 1990s, endocrine disrupting compounds have been recognized as an important environmental threat. Male fish exposed to effluent from large, metropolitan municipal wastewater treatment facilities (WWTFs) have developed reproductive abnormalities including ovotestes and elevated levels of plasma vitellogenin (Vtg), a plasma protein typically produced by egg-laying females. In the summer of 2000, gonads and plasma Vtg concentrations were examined in feral male fathead minnows (Pimephales promelas) collected from lagoons of 11 small, rural municipal WWTFs and a reference site (a national wildlife refuge) in Iowa. Fathead minnows were captured in traps from five of the 33 lagoons (three …

Cathodoluminescence As A Means For Distinguishing Hydrothermal From Pre-Hydrothermal Quartz In Sulfide-Bearing Mineral Deposits On The Northern Fringe Of The Upper Mississippi Valley Zinc-Lead District, Ne Iowa And Sw Wisconsin, Paul L. Garvin Jan 2003

Cathodoluminescence As A Means For Distinguishing Hydrothermal From Pre-Hydrothermal Quartz In Sulfide-Bearing Mineral Deposits On The Northern Fringe Of The Upper Mississippi Valley Zinc-Lead District, Ne Iowa And Sw Wisconsin, Paul L. Garvin

Journal of the Iowa Academy of Science: JIAS

Sulfide-bearing mineral deposits, located on the northern fringe of the Upper Mississippi Valley Zinc-Lead District, are contained in early Ordovician carbonate rocks that are extensively silicified and dolomitized. Some silica and dolomite appear to be products of the hydrothermal processes that also formed fracture-filling and cavity-lining sulfides and other cogenetic minerals; other silica and dolomite appear to result from low-temperature, pre-hydrothermal regional diagenesis. Distinguishing hydrothermal quartz (jasperoid) from pre-hydrothermal quartz (chert) solely by hand specimen and thin section petrography is difficult because these two types of mineralization are often intimately associated with each other. Polished slabs from several of these …

Salt Tolerance Of Sunflower And Lettuce In Cultivated And Uncultivated Grass Soil, Steven H. Emerman, Emily M. Kinsinger Jan 2003

Salt Tolerance Of Sunflower And Lettuce In Cultivated And Uncultivated Grass Soil, Steven H. Emerman, Emily M. Kinsinger

Journal of the Iowa Academy of Science: JIAS

We tested two hypotheses: 1) whether a vegetable crop will show greater growth under a given salinity treatment in an uncultivated grass soil than a cultivated soil and 2), if so, whether the greater growth is due to the occasional presence of relatively fresh water in macropores or the interaction between salinity and hypoxia in a soil without significant macropores. A previous study suggested uptake from. macropores was significant only for crops with high root water potential (Emerman and Dawson 1997). Hence, in this study, 21 miniature crops were grown in a greenhouse, and the ratio of root dry weight …

A Key To The Eggs And Nests Of Iowa Turtles, James L. Christiansen, Jeffrey R. Parmelee Jan 2003

A Key To The Eggs And Nests Of Iowa Turtles, James L. Christiansen, Jeffrey R. Parmelee

Journal of the Iowa Academy of Science: JIAS

Biologists often need to identify destroyed turtle nests where a predator has excavated and eaten the eggs. We present a dichotomous key to the eggs and nests of Iowa's turtles based on egg or nest morphology and known range of the species. Egg and nest morphology clearly separated most nests of the families Chelydridae and Kinosternidae and many of the Emydidae. However, egg morphology must be combined with known range to distinguish wood turtles (Glyptemys insculpta) from other emydids. These factors will also separate most false map turtles (Graptemys pseudogeographica) from other species. Similarities among egg morphologies, nest morphologies, and …

Submersed Aquatic Vegetation Trends In Impounded And Backwater Habitat Types Of Pool 13, Upper Mississippi River System: 1994-2000, Theresa A. Blackburn, Daniel J. Kirby Jan 2003

Submersed Aquatic Vegetation Trends In Impounded And Backwater Habitat Types Of Pool 13, Upper Mississippi River System: 1994-2000, Theresa A. Blackburn, Daniel J. Kirby

Journal of the Iowa Academy of Science: JIAS

Submersed aquatic vegetation (SAV) was sampled from 1994-2000 at fixed sires along established transects in Pool 13 of the Upper Mississippi River System (UMRS), as part of the Long Term Resource Monitoring Program (LTRMP). These data were used to quantify the annual percent frequency of occurrence and mean relative density of SAV within three backwaters (Brown's Lake, Savanna Bay, and Spring Lake) and the impounded area of Pool 13. This investigation used Spearman rank correlation to assess the strength of bivariate relationships between measurements of SAV abundance and biological, physical, and hydrological variables at fixed water quality monitoring sites within …

The Influence Of Soil Water Content, Calcite Content, And Temperature On Bulk Electrical Conductivity, Eric C. Brevik, Jaehoon Lee, Thomas E. Fenton, Robert Horton Jan 2003

The Influence Of Soil Water Content, Calcite Content, And Temperature On Bulk Electrical Conductivity, Eric C. Brevik, Jaehoon Lee, Thomas E. Fenton, Robert Horton

Journal of the Iowa Academy of Science: JIAS

Electrical conductivity (EC) as measured by the Geonics® EM-38 has shown promise as a soil survey tool. EC is determined by a combination of soluble salts, clay content and mineralogy, water content, and temperature. While investigating use of the EM-38 for soil survey purposes, it is important to understand the relative contribution of each of these variables on EC. A laboratory experiment was set up to determine the relative influence of water content, temperature, and calcite content on EC using time-domain reflectometry (TDR) probes. TDR was used as a proxy for the EM-38 because of the large volume of soil …

An Assessment Of Water Quality In Ensign Hollow, Clayton And Fayette Counties, In Northeast Iowa, Rick Klann, Jaime Platts Jan 2003

An Assessment Of Water Quality In Ensign Hollow, Clayton And Fayette Counties, In Northeast Iowa, Rick Klann, Jaime Platts

Journal of the Iowa Academy of Science: JIAS

Water quality and benthic invertebrates in the Ensign Hollow watershed, southwestern Clayton County and southeastern Fayette County, Iowa, were monitored from 2000 to 2001. Measurements of physical and chemical parameters of water quality, as well as analysis of benthic invertebrates, all indicated that streams of the Ensign Hollow watershed were exposed to slight organic pollution. Furthermore, the greatest threat to this watershed appeared to be sedimentation introduced through runoff.

A Framework For Reproductive Models Of Mourning Doves, David L. Otis Jan 2003

A Framework For Reproductive Models Of Mourning Doves, David L. Otis

Journal of the Iowa Academy of Science: JIAS

Population models can be used to aid in development and evaluation of harvest management strategies for game species. No current models are available for the Mourning Dove (Zenaida macroura), which is considered a migratory game bird in 37 states. A predictive model for annual reproduction is a necessary component of such a model. I used a simple construct based on parameters of the Mourning Dove breeding cycle to develop probability distributions of annual per capita reproduction for each of five geographical regions in the U.S. Confidence intervals for model predictions included average estimates from published studies in all regions except …

Recent Observations Of The Distribution And Status Of Freckled Madtom And First Record Of Spotted Gar In Iowa, Melvin C. Bowler Jan 2003

Recent Observations Of The Distribution And Status Of Freckled Madtom And First Record Of Spotted Gar In Iowa, Melvin C. Bowler

Journal of the Iowa Academy of Science: JIAS

The distribution and status of Iowa's fishes were last extensively described in Iowa Fish and Fishing (Harlan et al. 1987). Since then, numerous fish collections have been made in Iowa's interior and bordering rivers and streams. In this paper, I describe recent collections of freckled mad tom (Noturus nocturnus) and spotted gar (Lepisosteus oculatus) from the Upper Mississippi. River (UMR). Six specimens of N. nocturnus were collected from Pool 13 of the UMR in 2001. Although the first documented specimens of N. nocturnus in Iowa were collected in the English River in 1984, few collections have been made throughout the …

The Glass Ceiling For Women In Business, Megan Abels Jan 2003

The Glass Ceiling For Women In Business, Megan Abels

Presidential Scholars Theses (1990 – 2006)

What better inspiration for research on the glass ceiling than the words of such influential women. As a young woman who will soon graduate college and enter the business world, in a field still dominated by men, the glass ceiling was a natural choice for my Presidential Scholar's research. When I first heard mention of the topic, it sounded like an age-old concept; one that was no longer in the public perception for the simple fact that it no longer existed. All my life, I have been led to believe that as a woman I can do anything, and that …

Creating Chaos: Us' Policies In The Democratic Republic Of Congo, Kelly Shell Jan 2003

Creating Chaos: Us' Policies In The Democratic Republic Of Congo, Kelly Shell

Presidential Scholars Theses (1990 – 2006)

Since 1885, when the United States' government became the first to officially recognize King Leopold's claim to the Congo, the United States has continuously undermined the democratic attempts and economic prosperity of the Congolese population. Throughout the DRC's political history the United States has successfully used covert operations under the guise of the United Nations, clandestine CIA maneuvers, and/or the pretense of humanitarian relief to control American interests in the Great Lakes Region. Although other western nations have used their own means to advance their interests in the Congo, this paper will focus on the US' role in the Congo. …

Recent Jewish Immigrants' Communication In Postville, Iowa: A Case Study, Anna I. Levina Jan 2003

Recent Jewish Immigrants' Communication In Postville, Iowa: A Case Study, Anna I. Levina

Dissertations and Theses @ UNI

For this paper the author researched Iowa's immigration history and modern day Postville, a small town that represents a tossed salad of cultural, religious, and linguistic diversities. The author analyzed the current effect of immigration as well as the process of integration and assimilation into the small town through the eyes of its immigrants. The major emphasis is placed on Postville located in northeast Iowa. For 150 years Postville was an all-white, all-Christian farming community of 1,000 souls, most of European ancestry. Today the population of Postville has doubled and of the 2,000 people who reside in Postville almost one …

Breaking The Stereotypes: Influences And Characteristics Of Academically Talented Women, Joy Leigh Daggs

Dissertations and Theses @ UNI

I was in fifth grade when I heard the word "gifted" for the first time. I had little idea what it meant, but once I was identified that way, my life as a student began to change. I was suddenly expected to perform at my highest level with very little room for error. I learned about the expectations of my performance from my peers, teachers, and parents. They sent me very clear messages about how I was to perform as an academically talented woman. My experience has shaped my research interest for this thesis. In this thesis, I will explore …
