Essays On Fall Fertilizer Application, Mira Nurmakhanova Jan 2008

Essays On Fall Fertilizer Application, Mira Nurmakhanova

Retrospective Theses and Dissertations

Increased use of nitrogen fertilizer in agricultural production has contributed to increased food production but also contributed to elevated concentration levels of nitrates in groundwater and surface water. High concentration levels of nitrates in drinking water supplied from groundwater and surface water have become a public concern because of their risks to human health.;One way to reduce nitrogen losses is to develop and apply technologies that enable farmers to more accurately match the amount and timing of fertilizer application to crop growth needs. It is best to apply nitrogen as close as possible to when crop needs it most ...


Syncretism: A Study Of Toshodai-Ji Wayo Architectural And Cultural Elements, Carole N. Edginton Jan 2008

Syncretism: A Study Of Toshodai-Ji Wayo Architectural And Cultural Elements, Carole N. Edginton

Retrospective Theses and Dissertations

When cultures come in contact with another an exchange of social constructs occurs. Very often this results in a syncretism or a blending of ideas which results in the development of new innovative ideas and materials. Wayo cultural traditions of Nara Japan are an example of this type of occurrence. With the transmission of Buddhism from China to Japan in 509 C.E. via Korea cultural, religious, political, as well as architectural advances in technologies occurred. Toshodai-ji successfully demonstrates the Buddhist ideology and methods of T'ang architectural design that was transferred to Japan from China. Wayo features are found ...

Educational Outcomes Of Children With Absent-Fathers: An Examination Of Children With Deceased Fathers And Children With Fathers Absent For Other Reasons Compared With Children With Fathers Present In A Two-Parent Home, Brandie Marie Ward

Retrospective Theses and Dissertations

Educational outcomes for children with fathers absent due to death and those absent for other reasons were examined with children from two-parent homes using the Adolescent Health data. Children without fathers for any reason completed a year less of school than children living with two parents. Children with deceased fathers and children with fathers absent for other reasons did not differ in the amount of education each completed. There was no association between the child's age when the father died and the amount of education completed, but there was a small relationship between the length of time a child ...


Exploring The Relationship Between Income And Property Taxation At The Municipal Level, Casey J. Muhm Jan 2008

Exploring The Relationship Between Income And Property Taxation At The Municipal Level, Casey J. Muhm

Retrospective Theses and Dissertations

Municipalities in Iowa are heavily reliant upon property tax revenue as a means of finance; a phenomenon which many feel has negative implications for local governance. A frequently cited remedy for this is the diversification of municipal revenue sources by enabling municipalities to collect income tax. Proponents claim that doing so would allow municipal governments to become less dependent upon property tax revenue, as well as provide relief to property taxpayers in the form of lower rates and collections. The purpose of this thesis is to explore those claims by examining whether municipalities with income tax exhibit lower property taxes ...


Their Voices Emerged: A Grounded Theory Of Learning Resilience Among African American Women In The Formal Education Environment, Sandra L. Mcgee Jan 2008

Their Voices Emerged: A Grounded Theory Of Learning Resilience Among African American Women In The Formal Education Environment, Sandra L. Mcgee

Retrospective Theses and Dissertations

Rampant, negative messages about the capabilities of African American women in the education system pervade society. I suggest that these negative messages fail to account for Black women's learning resilience. In this study, the voices of 27 African American women who described their experiences in the formal education environment emerged through interviews, focus groups, observations, and two electronic interactions, participation in a chat room and e-mail exchanges.;This multigenerational study spans 71 years of educational experiences that I organized into five generations that correspond with eras of significance for both the African American culture and the education system. These ...

The Right Of Access, The Right To Hear, And The Right To Speak: Applying First Amendment Theories To The Network Neutrality Debate, Sarah Carpenter Barrow Jan 2008

The Right Of Access, The Right To Hear, And The Right To Speak: Applying First Amendment Theories To The Network Neutrality Debate, Sarah Carpenter Barrow

Retrospective Theses and Dissertations

Scholarship on the network neutrality debate has focused primarily on economic and technological arguments for or against regulation to protect the Internet's open and democratic qualities. Concerned that congressional discussion is similarly two-dimensional, this thesis examines the First Amendment concerns in the debate. Following Moran Yemini's 2007 paper, a matrix of possible First Amendment claims on the Internet is created. Legal case analysis identifies which of these claims are supported by Supreme Court precedent. The only potential First Amendment challenge to neutrality regulation would be broadband service providers' (BSPs') claim that the regulation infringed on their editorial rights ...

The Effect Of Prisonization On Female Criminality, Anna Elizabeth Kosloski Jan 2008

The Effect Of Prisonization On Female Criminality, Anna Elizabeth Kosloski

Retrospective Theses and Dissertations

Prisonization theory asserts that inmates who internalize the attitudes and behaviors of a criminal lifestyle are most likely to continue their criminal careers and thus less likely to desist from crime. Unfortunately, virtually all prior studies of prisonization have used male samples and ignored female inmates. Using official data from 174 female inmates in Arizona, the current study examined predictors of 10 forms of institutional misconduct. Net the effects of demographic, social history, criminal career, and other risk factors, women who had served prior prison terms were significantly likely to commit all forms of misconduct. The effect of prior prison ...

"I Hope To Share My Struggles, My Successes, And Everything In Between": A Rhetorical Study Of Health Blogs, Marcy Deborah Leasum

Retrospective Theses and Dissertations

Many patients who are experiencing a serious illness need a way to express their emotions and continue their everyday lives. For some patients, one outlet is through a health blog. Health blogs allow these individuals to share their emotions about their illness through narrative and with a wide audience over the Internet.;The visual and textual elements of health blogs work together to create an identity that is unique to each blogger. As these visual and textual elements combine, one can see the narratives emerge. Through these narratives, the bloggers persuade both themselves and others that they can to some ...

The Land, It's Everything: Women Farmland Owners And The Institution Of Agricultural Conservation In The U.S. Midwest, Jean Crim Eells

Retrospective Theses and Dissertations

This institutional ethnography was undertaken to address the problematic that far fewer women than men participate in the institution of agricultural conservation despite the fact that about the same numbers of men and women own roughly equal amounts of agricultural land in the U.S. Midwest. The institution of agricultural conservation---governmental agencies and private non-profit organizations---provides conservation services such as technical assistance and funding to clients, private farmland owners, who implement conservation practices on their lands.;As a qualitative research methodology, institutional ethnography (IE) is a way to examine otherwise intractable or elusive problems that exist on an institutional level ...

The sector is characterized by large wage premia paid to workers on larger and more ...


Cosmetic Technologies Of The Body: An Exploration Of Self And Identity Through The Consumption Of Nonsurgical Cosmetic Procedures, Keila Elizabeth Tyner Jan 2008

Cosmetic Technologies Of The Body: An Exploration Of Self And Identity Through The Consumption Of Nonsurgical Cosmetic Procedures, Keila Elizabeth Tyner

Retrospective Theses and Dissertations

Although much research has been conducted on cosmetic surgery and some research has been conducted on cosmetic use in general, little to no research has explored nonsurgical cosmetic technologies of the body, particularly as a symbolic form of consumption in shaping notions of the self. Thus, the purpose of the present qualitative study was to gain understanding of the consumption of nonsurgical cosmetic technologies of the body from multiple theoretical perspectives. Of particular interest was how this consumption serves as a symbolic means for shaping the self, specifically in the context of self-presentation and impression management (Goffman, 1959).;For this ...

A total of 34 participants (16 male and 18 female) were included in the final sample. Participants completed a measure of violent and sexual media exposure and the Beliefs About Preventing AIDS (BAPA) measure. Participants were shown movie clips with varying subject matter while their physiological arousal (heart rate and skin conductance) was recorded. Gender, media exposure, and sexual attitudes were not significant predictors of physiological response to violent and sexual media. Males and females did not differ on any ...


Reference Models For Network Trace Anonymization, Shantanu Gattani Jan 2008

Reference Models For Network Trace Anonymization, Shantanu Gattani

Retrospective Theses and Dissertations

Network security research can benefit greatly from testing environments that are capable of generating realistic, repeatable and configurable background traffic. In order to conduct network security experiments on systems such as Intrusion Detection Systems and Intrusion Prevention Systems, researchers require isolated testbeds capable of recreating actual network environments, complete with infrastructure and traffic details. Unfortunately, due to privacy and flexibility concerns, actual network traffic is rarely shared by organizations as sensitive information, such as IP addresses, device identity and behavioral information can be inferred from the traffic. Trace data anonymization is one solution to this problem. The research community has ...

Does Balance Training Improve Balance In Physically Active Older Adults?, Kristen Kartchner Maughan Jan 2008

Does Balance Training Improve Balance In Physically Active Older Adults?, Kristen Kartchner Maughan

Retrospective Theses and Dissertations

Falls among older adults are a growing public health problem. Previous research suggests that the regular practice of physical activity in older adults improves balance and reduces falls. The objective of this study was to determine whether balance-specific training, in addition to regular physical activity, could improve balance in older adults, and whether there would be a dose-response to frequency of balance training.;A six-week balance-training program was conducted with 60 older adults (60-87 years) who were already participating in a regular program of physical activity. All participants continued with their regular exercise program while adding balance training in one ...

Uncertainty And Evolution: Contributions To Identity Development For Female College Students Who Identify As Multiracial/Biracial-Bisexual/Pansexual, Alissa Renee King

Retrospective Theses and Dissertations

In this study, I explored how female college students who identify as multiracial/biracial-bisexual/pansexual made meaning of their racial and sexual identities, how they described their identity development process, and the ways in which college contributed to their identity formation. Utilizing a proposed model of biracial-bisexual identity development and the ecology of student development model as foundations for this study, I sought to better understand the experiences both before and during college, and the impacts of those two environments on the processes of racial and sexual identity formation for the female college students in this study. Findings, based on ...

The importance of the adoptive parents having a social support network and understanding of the child's birth culture were ...


Gay Men's Experiences Of Alaskan Society In Their Coupled Relationships, Markie Louise Christianson Blumer Jan 2008

Gay Men's Experiences Of Alaskan Society In Their Coupled Relationships, Markie Louise Christianson Blumer

Retrospective Theses and Dissertations

Although it is true that male-male couples are more similar to rather than different from female-male couples, there are unique challenges and positive aspects for gay partnerships related to their existence in what continues to be a society of non-support. Little research exists on supportive and non-supportive experiences of gay males in society, particularly how these experiences affect their relationships, and information with regard to this topic is virtually non-existent in the remote state of Alaska. Therefore, this qualitative study, informed by constructionist frameworks, gave voice to eleven gay males currently involved in partnerships with a focus on exploring their ...

Pregnant And Parenting Teens' Attitudes Toward Pregnancy And Motherhood And Their Perceptions Of Social Support, Cindy Ngoc Vo Jan 2008

Pregnant And Parenting Teens' Attitudes Toward Pregnancy And Motherhood And Their Perceptions Of Social Support, Cindy Ngoc Vo

Retrospective Theses and Dissertations

This study investigated the social support network of pregnant (n=10) and parenting (n=22) teens recruited through local agencies. The support network was viewed both as support and as an agent of stress to adolescents. The pregnant and parenting teens' perceptions of motherhood and their attitudes toward being a parent were also studied. The teens had a variety of support types and support sources, but the two groups did not differ in those types and sources. They preferred support from boyfriend and mother over other sources and both groups had similar expectations and beliefs about motherhood and social support ...
