A phenomenological approach was used to interpret the stories shared by participants to understand how the Latina women ...


Insuring Uncertainty In Value-Added Agriculture: Ethanol, Nicholas David Paulson Jan 2004

Insuring Uncertainty In Value-Added Agriculture: Ethanol, Nicholas David Paulson

Retrospective Theses and Dissertations

A wide variety of insurance products are currently available for agricultural producers to insure against yield or price risks in the markets for the raw commodities they produce. Value-added enterprises, such as ethanol production, have become increasingly popular among farmers over the last decade; however, insurance against declines in the value-added portion of their crops is not yet available. This paper outlines the development of an insurance product aimed at corn producers who are members of an ethanol production cooperative. The product mimics the gross margin level of a typical ethanol production facility, and has the potential to provide producers ...


The Federal Reserve System And The Federal Funds Rate: Evaluating The Fed's Rate-Targeting Decisions Through The Use Of Taylor-Type Monetary Policy Rules, Michelle Lynn Mireault Jan 2004

The Federal Reserve System And The Federal Funds Rate: Evaluating The Fed's Rate-Targeting Decisions Through The Use Of Taylor-Type Monetary Policy Rules, Michelle Lynn Mireault

Retrospective Theses and Dissertations

In the U.S., monetary policy decisions are handled by our central bank, the Federal Reserve System. By targeting a desired interest rate level and using three main "tools" to adjust the money supply in order to achieve this rate, the Federal Reserve guides our economy in order to maintain its long-term goals of price stability and sustainable economic growth. To help the public better understand the actions of the Federal Reserve, economist John B. Taylor devised a monetary policy rule in 1993 that is both simple and reasonably accurate. In the decade since his pivotal rule, numerous researchers have ...


The Economic Potential Of Switchgrass As A Viable Biofuel Alternative, Jennifer E. Reutzel Jan 2004

The Economic Potential Of Switchgrass As A Viable Biofuel Alternative, Jennifer E. Reutzel

Retrospective Theses and Dissertations

To be commercially viable as a bioenergy feedstock, switchgrass must be cost-competitive. Switchgrass production and delivery costs are calculated for the Chariton Valley Switchgrass Biomass Project located in the Chariton Valley, Iowa. Sensitivity analyses are performed to determine which variables have the greatest impact on cost. Switchgrass production costs would require higher than expected market prices, and therefore various incentive payment options are considered. The incentive payments attempt to encapsulate the positive environmental attributes from the production of switchgrass as well as using switchgrass as a clean energy coal substitute. A modified CRP payment, carbon payment, and green tag payment ...


Examining Esl Students' Vocabulary Retention In An On-Line Environment Using The Mental Effort Hypothesis, Jennifer Anne Oden Jan 2004

Examining Esl Students' Vocabulary Retention In An On-Line Environment Using The Mental Effort Hypothesis, Jennifer Anne Oden

Retrospective Theses and Dissertations

The advent of computer-assisted language learning (CALL) materials has revolutionized teaching as increasing numbers of educators realize the power of the medium. With the proliferation of these materials comes a need for developers to make informed choices about the materials they create. In studies using traditional print materials, researchers have discovered the importance of glossing difficult vocabulary words; however, the method of glossing varies greatly. More research is needed to inform the decisions educators make about the types of glosses to offer. The research questions shaping this study are: 1) Does a multiple-choice option that requires students to expend mental ...


Study, Practice, And Pedagogy Of Idea Formation In Rhetoric And Professional Communication , Iraj Omidvar Jan 2004

Study, Practice, And Pedagogy Of Idea Formation In Rhetoric And Professional Communication , Iraj Omidvar

Retrospective Theses and Dissertations

The collapse of traditional epistemology, which began in the nineteen hundreds in Europe, removes many of the traditional distinctions between philosophy and rhetoric and significantly expands the scope of the latter. This dissertation explores some aspects of the new definition of rhetoric that emerges from this collapse. This definition emphasizes how we form ideas (decisions, judgments, theories, but also names and images) by communicating as we work together to solve problems and to decide courses of action by examining social/cultural, institutional, and individual values. "How Professionals Form Their Ideas: An Urgent Research Direction for Rhetoric and Professional Communication" argues ...

Corporate Hedging And The Cost Of Debt, David Christopher Alley Jan 2004

Corporate Hedging And The Cost Of Debt, David Christopher Alley

Retrospective Theses and Dissertations

This paper develops a set of necessary conditions to justify corporate hedging using a general cash flow model of firm value when the cost of debt is convex in both level of debt and the value of the firm's assets. It is shown that hedging is value-creating under a wider range of conditions than suggested in the existing hedging literature. By hedging, the firm is able to rely less on externally generated funds and, therefore, will invest at a higher level than when using borrowed funds. Furthermore, if external financing is necessary, the firm will be able to borrow ...

Using multiple methods of data collection (in-depth interviews, informal observations, documents, artifact, member checks, and peer debriefings), this research attempts to shed light on how an immigrant woman makes sense out of her social world through the languages she uses, their function in her life, the meanings she assigns to each and the role of learning languages on her multilingual identity. Some SLA investigators have argued that because ...


Navigating The Workplace: Gay White Men In Corporate America , Shaun Bryant Keister Jan 2004

Navigating The Workplace: Gay White Men In Corporate America , Shaun Bryant Keister

Retrospective Theses and Dissertations

The lives of gay men and lesbians continue to be understudied in sociology. In addition, gay white men are uniquely positioned in society, at once belonging to the dominant culture by virtue of being both "white" and "male," and part of a minority group because of their sexual orientation. This distinction is important to acknowledge and study. Additionally, because sexual orientation can be hidden or made invisible, the ability to choose if and when one might divulge their orientation adds a unique dimension to how gay white men navigate their lives. This body of research specifically examines how gay white ...

Effects Of A Minimum Wage Increase On The Employment Of Disabled Persons, Andrew Mikael Larsen

Retrospective Theses and Dissertations

The purpose of this paper is to examine the effects of a minimum wage change on the employment of disabled persons. Minimum wage changes may take place at either the federal or state level. Using data from the Survey of Income and Program Participation (SIPP) this study concludes that there is an insignificant increase in the employment of disabled persons following an increase in the minimum wage. More precisely, the results propose that a 10% increase in the minimum wage leads to a 0.6% increase in the employment of disabled persons. The study conducts simulations of various hypothetical policy ...


Adolescents And Consent To Counseling: The Adolescents' Perspectives , Summer Kaye Brunscheen Jan 2004

Adolescents And Consent To Counseling: The Adolescents' Perspectives , Summer Kaye Brunscheen

Retrospective Theses and Dissertations

Informed consent for counseling is a complex process for both clients and clinicians, even when individuals are over eighteen years of age. When working with adolescent minors, the process requires additional consideration. Informed consent, a legal term and ethical construct, is composed of tenets that require deliberate thought and action on the part of a therapist to ensure the client's understanding of the nature and expectations for counseling and voluntary participation. There are numerous legal and research controversies pertinent to competency of adolescents to accord informed consent for counseling and what procedures should be used to solicit adolescent consent ...


The Taj Mahal Of Sport: The Creation Of The Houston Astrodome, 1957-1967 , Jason Bruce Chrystal Jan 2004

The Taj Mahal Of Sport: The Creation Of The Houston Astrodome, 1957-1967 , Jason Bruce Chrystal

Retrospective Theses and Dissertations

This dissertation explores the creation of the Houston Astrodome, the first domed stadium built in the United States, from its earliest history of planning in the late 1950s to its construction and completion in the mid-1960s. It is during the time frame of 1957 to 1967, I argue, that we can see an example of the change in Houston and American society from one of an era of optimism and prosperity to one of pessimism and scarcity. By examining the arguments of stadium supporters and opponents, the alterations in design, the selection of certain technologies, and the changing opinion of ...

Valuing the improvement of water quality in Iowa lakes is the objective of this dissertation. In the first two essays, the focus is combining revealed preference and stated preference data from an intercept survey at a northcentral Iowa lake. In the first essay, the contingent behavior trips which are contingent on the price (i.e. travel cost) of the recreation trip are combined with observed trips. However, since this data set was collected on-site, the primary purpose of the first essay is to consider controlling for on-site sampling with a panel data set. A count data model is employed, specifically ...


Esl Students' Use Of Concordances And Dictionaries In The Transfer Of Academic Word Knowledge: A Comparative Study, Jagdish Kaur Jan 2004

Esl Students' Use Of Concordances And Dictionaries In The Transfer Of Academic Word Knowledge: A Comparative Study, Jagdish Kaur

Retrospective Theses and Dissertations

Concordancing in the classroom is fairly a new approach which has emerged with the use of corpora in language learning. In a concordance, language is presented in natural setting; learners are able to examine a key word in the context of a string of sentences which can exemplify the use of that particular word. Learners need not rely heavily on their teachers or their own intuition as they can explore specific language features from the vast amount of information in the corpora. Vocabulary knowledge acquired from a concordance can be transferred to novel texts (Cobb, 1999) to enhance student writing ...

Supply Chain Management Of Differentiated Agricultural Products Under Imperfect Information , Miguel Alberto Carriquiry Jan 2004

Supply Chain Management Of Differentiated Agricultural Products Under Imperfect Information , Miguel Alberto Carriquiry

Retrospective Theses and Dissertations

Participants in a supply chain of agricultural value added products face two significant challenges. First, many of the costly distinctive traits being desired by consumers are difficult (if not impossible) to observe even after consumption. In order for markets for these classes of goods to develop, firms touting the quality of the product need to be trusted. Hence, maintaining an excellent reputation is essential for firms to keep their customers' good will. Secondly, production is conducted in an environment of yield uncertainty, making it impossible for producers and processors to predict with certainty either the quantity or the quality of ...


Threshold Cointegration Test Of The Fisher Effect , Biyong Xu Jan 2004

Threshold Cointegration Test Of The Fisher Effect , Biyong Xu

Retrospective Theses and Dissertations

According to the Fisher hypothesis, the nominal interest rate moves one-to-one with the rate of inflation anticipated by the public, and the expected real rate of return is constant over time. The hypothesis implies that in the long run there is a one-to-one correspondence between changes of the nominal interest rate and the changes of inflation, which is often referred to as the Fisher effect in the literature.;To test the Fisher hypothesis, most of the previous empirical studies are using linear models in time series, which was predicated on the assumption that the path of adjustment towards long-run equilibrium ...

Use Of The Oral History Interview To Assess Communication And Marital Satisfaction In Later-Life Couples , Daniel James Harkness

Retrospective Theses and Dissertations

A study was designed to explore the content and process of marital history storytelling in later life couples and the relationship of storytelling content and process to marital satisfaction. Fifty-six Caucasian couples ranging in age from 47--83 years were recruited for participation in the study. Each spouse completed the Satisfaction subscale of the Dyadic Adjustment Scale (DAS; Spanier & Cole, 1974) and couples participated in an Oral History Interview (Buehlman, Gottman, & Katz, 1992) designed to elicit their marital history story. Research team members viewed each interview and obtained consensus scores for each couple using the Global Assessment of Relational Functioning (GARF; APA, 1994). All interviews were transcribed and data was segmented into thought units and speeches. The Relationship Path Coding System (RPCS) was designed to code thought units in marital stories according to content and process variables. Content variables included amount of detail ...


Pre-Prison, Prison, Post-Prison: Post Traumatic Stress Symptoms , Daniel Shawn Murphy Jan 2004

Pre-Prison, Prison, Post-Prison: Post Traumatic Stress Symptoms , Daniel Shawn Murphy

Retrospective Theses and Dissertations

Those sentenced to prison bring with them individual characteristics acquired prior to incarceration. This study assesses the effect of pre-prison experiences on adjustment to the prison environment. Regression analysis indicates that pre-prison experiences are significantly related to the likelihood of participating in, or being exposed to, elements of the incarceration experience that may cause post traumatic stress symptoms. A second component of this study assesses the relationship between elements of the incarceration experience and post traumatic stress symptoms. Regression analysis indicates that aspects of the incarceration experience constitute traumatic stressors that cause post traumatic stress symptoms in some individuals. This ...
