Behavioral Responses Of Male Parasitic Wasps To Plant Cues: A Comparison Of Two Host-Plant Complex Sources Of Cotesia Congregata (Say), Megan Ayers

Theses and Dissertations

Prior exposure to plants cues can enhance assortative mating in insects. We hypothesized that, as previously reported for females, males of Cotesia congregata would display inherent responses to plant cues that could be modified by postemergence experience and further, that males originating from two different host-plant complexes (HPCs) would display different behavioral responses to these HPCs. In no-choice contact assays with a non-host plant, searching responses of males and females increased sharply at Day 2 and remained stable through Day 4. In no-choice assays with potential host plants, males searched longer on catalpa than tobacco; responses were not modified by …

Oasis Link, Sarah Baugh

Theses and Dissertations

This document is written from the perspective of the Oasis Link community, a group of dissidents who have resettled in the Mojave Desert sometime in the near future. It is a speculative design document.

Surface is what is visible. It’s the crust of the earth and the face of a meteorite—the coat of a jackrabbit and the waxy skin of a Mojave Prickly Pear. Surface is superficial, but it also reflects and defines the underlying structure of something—it makes the hidden visible.

Reconnect: Designing To Touch, Dana Seros Rohani

Theses and Dissertations

Our everyday lives are surrounded by gadgets and digital devices that help us perform our daily chores with ease and efficiency. However, these digital devices can also separate us from what we should do ourselves. Although children who are exposed to high levels of technology might become attuned to the latest and the best gadgets, they might not learn to use their physical abilities. Another implication of a child’s over dependence on technology is that parental interactions such as encouragement, tutoring and reinforcement are provided by gadgets rather than living, breathing parents. Research done by Padma Ravichandran and Brandel France …

Detection And Cancellation Of Sinusoidal Fading Power Variation In Wireless Communication Systems, Sushruth Sastry

Masters Theses

"Fading channel estimation in wireless communication systems depends on an expected model for fading and any assumptions made about the channel itself. The bit error rate (BER) performance of the communication system is affected by how closely these assumptions made in designing the estimation technique match the deployment environment. Any unforeseen disturbances or hindrances in the environment deteriorate the BER performance of the system when the estimation system is not designed to combat such disturbances. To deal with such unforeseen obstacles, additional mathematical models can be proposed to model such disturbances and then the estimation techniques can either be reinforced …

Biodiversity And Ecosystem Function And The Design Of Tallgrass Restorations For Biomass Production, Dustin Robert Jon Graham

Dissertations and Theses @ UNI

Biodiversity and ecosystem function research (BEF) suggests species richness may provide high levels of ecosystem functions. However, few studies have applied a BEF perspective of restoration, which utilizes biodiversity to achieve increases in ecosystem functions. In this study, we test the application of the BEF perspective of restoration in the design of tallgrass prairie plantings as a biomass crops. Specifically, we examine the effects of planted species richness on biomass production, resistance to disturbance, and resistance to invasion by weeds.

Four seed mixes which range in species richness (1, 5, 16 and 32 species) were established in four, field-scale (0.33-0.55 …

Stars, Stripes, And Swastikas : The American Turners And National Identity, 1935-1945, Amy Rekward

Dissertations and Theses @ UNI

Although German Americans were unable to completely recover from the discrimination endured during World War I, the American Turners proved to be a resilient group. Despite the insistence of some scholars that the German-American community in the United States lost the battle for cultural pluralism, from 1935 to 1945, the American Turners continued to craft and foster a unique Turner identity. Composed of what members perceived to be the best aspects of their German and American identities, the Turner identity allowed American Turners to both valorize their German heritage and present themselves as devoted Americans. My research into the American …

Danish Cedar Falls : The Immigrant Experience, Carrie L. Eilderts

Dissertations and Theses @ UNI

The Danish were the largest immigrant group in Cedar Falls. They immigrated to Cedar Falls and the nearby rural village of Fredsville in large numbers between 1870 and 1900. There they formed an immigrant community. The lived near each other, worshipped together, spoke the same language, and carried on Danish traditions. They farmed, found jobs in Cedar Falls businesses, and opened businesses of their own. By the 1930s, as the first generation of Danish immigrants grew old, the younger generations began to identify more as Americans than as Danes. The elements that characterized the Danish immigrant community began to disappear. …

August Becker And Traditional Vs. Modern Culture In The First Decades Of The Twentieth Century, Michelle Lea Becker Smith

Dissertations and Theses @ UNI

In the first few decades of the twentieth century, American culture changed drastically from the traditional agricultural culture that had sustained it for a century to one that was modern and revolved around the urban landscape, consumer culture, and manufacturing. In this thesis I explore this change in American culture through the life of August Becker, son of a rural German immigrant who chose a life of crime instead of staying in rural Iowa. His life choices are the lens used to explore the changes in American culture through the first decades of the twentieth century.

This paper will examine primary and secondary sources throughout the 19^th and 20^th centuries that mark a change in just how Humboldt was remembered, once as a great thinker, philosopher, and romanticist, then eventually as little more than an empirical scientist. This thesis will contribute to modern understandings of this man by looking at popular publications and writings that track this change over time. It will contribute to the modern understanding …

Different Levels Of Negative Emotions And Their Impact On Prosocial Behavior, Tsamchoe Dolma

Dissertations and Theses @ UNI

In this fast and competitive world, people are becoming less likely to help others. According to the Bureau of Labor Statistics (2014), the volunteerism rate reached the lowest point in 2013 since 2002. This decrease in prosocial behavior makes the study of prosocial behavior important, especially with the increasing numbers of charitable organizations and their competition to attract more donors and volunteers. Public service advertisements (PSA) are used as a common medium to garner help and support, and many of them use emotional appeals to enhance persuasion. The literature on persuasion shows that emotions have persuasive power to change people's …
