Competition Between Chimpanzees And Humans Over Fruit Of Saba Senegalensis In Southeastern Senegal, Michel Tyler Waller Jan 2005

Competition Between Chimpanzees And Humans Over Fruit Of Saba Senegalensis In Southeastern Senegal, Michel Tyler Waller

Retrospective Theses and Dissertations

of wild growing plants in the Tomboronkoto region of southeastern Senegal. Due to political, economic, and demographic factors, the number of people collecting the fruit of the Saba senegalensis vine, an important food for chimpanzees and humans at a time of limited food diversity, is increa ing at a rate that may not be sustainable (Knutsen 2003). For humans, the fruit represents a much needed source of income at a time when crop stores are depleted and new crops have yet to produce. Often collected by women, the income derived from the Saba senegalensis harvest is used to buy clothing ...

Poverty And Food Insecurity In Rural Iowa: An Examination Of Four Food Desert Counties , Ella Annette Bitto Jan 2005

Poverty And Food Insecurity In Rural Iowa: An Examination Of Four Food Desert Counties , Ella Annette Bitto

Retrospective Theses and Dissertations

Pockets of poverty are found throughout rural Iowa. Rural America is comprised of people with varying backgrounds who much make their livelihoods in a society that is increasingly a part of a global village. Living in Iowa, called by many the breadbasket of the world, does not necessarily mean that everyone will have equal access to food. In fact, over 46,600 Iowans between 2001--2003 experienced some form of poverty and 9.4 percent were defined as food insecure. This dissertation examines the economic structure of Iowa's counties to determine how agriculture and local business influence per capita income ...


Integration Of Technology Into The Instructional Practice Of New Teachers: Case Studies Of Beginning Teachers' Use Of Technology , Jon Michael Clausen Jan 2005

Integration Of Technology Into The Instructional Practice Of New Teachers: Case Studies Of Beginning Teachers' Use Of Technology , Jon Michael Clausen

Retrospective Theses and Dissertations

The purpose of this study is to investigate how two first-year teachers use technology with their students. Each teacher was encouraged to use technology with students at different times in their development as teachers. One teacher participated in Iowa State University's PT3 grant project as a member of the TechCo cohort and began her career at a traditional elementary school. The second teacher was not a member of the PT3 cohort, but began her career at a school that had been a partner with Iowa State University's PT3 grant project. A case study analysis of these teachers investigated ...


Minority Stress And The Well-Being Of Sexual Minority College Students Viewed Through The Lens Of A (Bio)Ecological Model Of Human Development , R. M. Johnson Jan 2005

Minority Stress And The Well-Being Of Sexual Minority College Students Viewed Through The Lens Of A (Bio)Ecological Model Of Human Development , R. M. Johnson

Retrospective Theses and Dissertations

Minority stress comes from "the juxtaposition of minority and dominant values and the resultant conflict with the social environment experienced by minority group members" (Meyer, 1995, p. 39). Because minority stress is additive to general stressors that are experienced by all people, stigmatized people must accomplish an adaptation effort above that required of similar others who are not stigmatized. Using Bronfenbrenner's bioecological systems theory of human development as a guiding framework, this study explored the key environments in sexual minority college students' developmental trajectories that contributed to or buffered minority stress(ors). As the results of this study show ...


The Structural Organization Of Cbnrm In Botswana , Kutlwano Mulale Jan 2005

The Structural Organization Of Cbnrm In Botswana , Kutlwano Mulale

Retrospective Theses and Dissertations

The devolution of natural resource management to local community groups is a dominant theme in contemporary discussion of common property natural resource management. Throughout much of Africa and other parts of the developing world Community Based Natural Resource Management (CBNRM) programs are being implemented. Though governments in Africa and other parts of the developing world embrace the idea of CBNRM, the actual process of devolution of natural resource management to local community groups is problematic. In some countries, like Zimbabwe for instance, the central government devolved natural resource management to district councils which are themselves arms of the central government ...


Asian International Students' Ethnic Identity, Spirituality, Acculturation, And Experience Of Racism: Relationship With Attitude Toward Seeking Professional Therapeutic Help , Anthony D. Santiago Jan 2005

Asian International Students' Ethnic Identity, Spirituality, Acculturation, And Experience Of Racism: Relationship With Attitude Toward Seeking Professional Therapeutic Help , Anthony D. Santiago

Retrospective Theses and Dissertations

The number of international students continues to grow in the United States, especially students from the Asian continent. However, research continues to show that Asian international students tend to under-use therapeutic services, even though they experience many of the common problems that all students face entering college. Before mental health practitioners and therapists can effectively work with these students, they need to understand international students in terms of their attitudes toward seeking professional therapeutic help and various proximal variables that may influence their attitudes.;The present study examined the relationship between ethnic identity, spirituality, acculturation, and racism with attitudes toward ...


Online Counseling: Dynamics Of Process And Assessment , Michael John Mallen Jan 2005

Online Counseling: Dynamics Of Process And Assessment , Michael John Mallen

Retrospective Theses and Dissertations

The rise in popularity and use of computer-mediated modes of communication such as email and synchronous chat have resulted in the potential for new delivery methods of mental health services. The present study investigated the dynamics of an initial counseling session held in a synchronous chat environment between therapists-in-training at various graduate programs across the country and a trained confederate posing as a client. Transcripts from the online sessions were analyzed to investigate therapist responses and interventions in the online environment. Therapists-in-training were also asked to respond to questions concerning their satisfaction with the experience, the relationship they were able ...

An Instructor's Viewpoint: Incorporating Interaction In Web-Based Training, Julie M. Summers

Retrospective Theses and Dissertations

The purpose of this study was to identify the role an instructor's pedagogical philosophy has on the development of online courses. Of specific interest was the inclusion of interaction, as interaction is generally perceived to influence the learning experience. The development and maintenance of an online course is a substantial task. Institutions take different approaches to providing support for the development of online courses. This study also explored how the level of institutional support impacted the instructor's design process.;Educational research has endorsed the benefits of using interaction in face-to-face and web-based settings. Results from this study indicated ...

The purpose of this research study was to investigate how interpersonal and spiritual resources influence well-being in a sample of older men and women residing in religious monastic communities. Participants for this study included 235 (164 women and 71 men) individuals, age 64 and older, from the Religious Order of St. Benedict. Two (Age) X Two (Gender) Analyses of Variance were used to analyze mean differences. Young-old persons had higher mean scores on close friendship, coping behaviors, and personal growth than did old-old individuals. However, old-old individuals had higher average scores on religious coping behaviors and depression than did young-old ...


Guests' Reservation Behavior In Two Online Distribution Channels , Cristian Virgiliu Morosan Jan 2005

Guests' Reservation Behavior In Two Online Distribution Channels , Cristian Virgiliu Morosan

Retrospective Theses and Dissertations

Perceived as a fast-growing business opportunity, the Internet has been adopted by many travel organizations as a new, competitive marketing tool in providing travelers not only with travel-related information but also with online transaction opportunities. Hotels have been making great effort to encourage travelers to reserve rooms directly on their Web sites while intermediaries have been positioned in a very competitive situation to encourage travelers to make reservations through their portals by offering discounted rates, rate comparison tools, and additional information about the property/destination. In this context, it is interesting to investigate why travelers make reservations online and what ...


Industrializing The Corn Belt: Iowa Farmers, Technology And The Midwestern Landscape, 1945-1972 , Joseph Leslie Anderson Jan 2005

Industrializing The Corn Belt: Iowa Farmers, Technology And The Midwestern Landscape, 1945-1972 , Joseph Leslie Anderson

Retrospective Theses and Dissertations

From 1945 to 1972 Iowa farmers remade their landscape in the image of an industrial model characterized by large-scale production, the substitution of capital for labor, strict cost accounting, specialization, and efficiency. Farm families were leaders in adopting new technology to solve their problems in the post World War II period, a contrast to the pre-war years when experts such as college educated professionals, journalists, and industry leaders advocated the application of industrial ideals to agriculture. Many farmers industrialized production because of a persistent postwar farm labor shortage and a cost-price squeeze in which the prices farmers paid for products ...


Personality And Mental Health As Predictors Of Rater Bias In Observational Data , Mark Richard Becker Jan 2005

Personality And Mental Health As Predictors Of Rater Bias In Observational Data , Mark Richard Becker

Retrospective Theses and Dissertations

Observational coding has become a common form of data collection in the social sciences. This popularity has largely been fueled by the advantage of objectivity these systems are said to provide over more traditional self- and other-report data collection techniques. However, it has been demonstrated that observational coding systems can suffer from a type of systematic error known as rater bias, which is variance in the data that is not attributable to the observational target (i.e., true variance), but rather is attributable to the rater (i.e., error variance). This study sought to better understand the causes of rater ...


Third Space Sites, Subjectivities And Discourses: Reimagining The Representational Potentials Of (B)Orderlands' Rhetorics , Adela C. Licona Jan 2005

Third Space Sites, Subjectivities And Discourses: Reimagining The Representational Potentials Of (B)Orderlands' Rhetorics , Adela C. Licona

Retrospective Theses and Dissertations

This dissertation identifies feminist third-space (both/and) consciousness in academic and non-academic contexts. Although dissimilar, both academic discourses and zines (self-published magazines) are comprised of complex rhetorical performances with implications for feminist practices of representation and the re-production of meaning. This dissertation analyzes academic third-space sites resulting from the crossing of disciplinary borders and activist zines as examples of nonacademic third space, with particular emphasis on representations of bodies and sexualities. Zines reveal (1) the transformative potentials beyond gender binaries; (2) the importance of revisioning histories; (3) the practices of what I term "reverso" (critical reversals of the normative gaze ...


Four Essays On Technology Adoption And Returns To Skill In The Us , Moohoun Song Jan 2005

Four Essays On Technology Adoption And Returns To Skill In The Us , Moohoun Song

Retrospective Theses and Dissertations

We investigate two plausible factors that may have affected changes in wage inequality: returns to higher education and returns to new technologies. The first two chapters examine the role of mathematics and verbal ability in estimating returns to advanced degrees. When average abilities within the major are treated as missing variables, we found that OLS estimates of returns to graduate education are underestimated. When average ability in the major is treated as part of an endogenous decision regarding whether to attend post-graduate degree programs, we find that students in majors with higher average mathematics skills are less likely to progress ...


Problem-Based Learning In An On-Line Biotechnology Course , James Daniel Cheaney Jan 2005

Problem-Based Learning In An On-Line Biotechnology Course , James Daniel Cheaney

Retrospective Theses and Dissertations

Problem-based learning (PBL) is a pedagogical tool that uses a "real world" problem or situation as a context for learning. PBL encourages student development of critical thinking skills, a high professional competency, problem-solving ability, knowledge acquisition, the ability to work productively as a team member and make decisions in unfamiliar situations, and the acquisition of skills that support self-directed life-long learning, metacognition, and adaptation to change. However, little research has focused on the use of PBL in on-line "virtual" classes. We conducted two studies exploring the use of PBL in an on-line biotechnology course. In the first study, ethical, legal ...


New Media Rhetoric And The Attention Economy: Creating A Material Space For The Humanities In The Emerging Technological Structures Of The 21st Century University , Anthony P. Ellertson Jan 2005

New Media Rhetoric And The Attention Economy: Creating A Material Space For The Humanities In The Emerging Technological Structures Of The 21st Century University , Anthony P. Ellertson

Retrospective Theses and Dissertations

This portfolio dissertation, comprised of three articles, seeks to clarify some of the trends and possibilities now open for new media communication by focusing on the material realities of the Web. New media and composition scholars are struggling with the materiality of digital technologies and their implications for pedagogy and literacy, often taking a materialist turn to understand them. The first article presents lessons, theories, student work, and students' interpretations of their work in an attempt to open a discussion on the material goals behind multimodal rhetorical practice. The second article presents a multimodal case study, which examines the creation ...


What Is Make-Believe Play?: Preschool Teachers' Perspectives , Joanna Jennifer Cemore Jan 2005

What Is Make-Believe Play?: Preschool Teachers' Perspectives , Joanna Jennifer Cemore

Retrospective Theses and Dissertations

The purpose of this research was to explore preschool teachers' understanding of make-believe play in order to aid understanding and enhance further use of teachers as informants in research on children's play. Participants included preschool teachers (n = 10) and faculty members ( n = 3) who teach early childhood educators. Their descriptions of play and make-believe play were examined through qualitative research methods, including individual interviews. In-depth analysis of the emergent themes used to describe play and make-believe play were conducted. Preschool teachers defined make-believe play as representational play that is intrinsically motivated. This report includes examination of definitions, comparisons between ...

Healthy Communities Equal Healthy Ecosystems? Evolution (And Breakdown) Of A Participatory Ecological Research Project Towards A Community Natural Resource Management Process, San Miguel Chimalapa (Mexico) , Isabel A. Gutiérrez-Montes

Retrospective Theses and Dissertations

In tropical forest regions throughout the world, forest fires are a major risk to the well-being and sustainable livelihood of rural communities. The Chimalapas region is one of the priority conservation areas in Mexico since it is one of the country's most important sources of water, supports exceptionally diverse ecosystems and species of flora and fauna. Unlike in temperate conifer forests, fire is extremely rare in the Chimalapas cloud forests, but after the 1998 fire events, forest fires are a constant threat in the region. These fires result from the indiscriminate use of fire in agricultural activities as well ...


Spanish Business Writing Genre Research: Electronic Mail Memoranda , Therese M. Judge Jan 2005

Spanish Business Writing Genre Research: Electronic Mail Memoranda , Therese M. Judge

Retrospective Theses and Dissertations

Despite the prevalence of a belief in the importance of preparing students for work in a global economy, very little research into Spanish-language written communication practices exists. In this study, I formed hypotheses regarding Mexican business e-mails based on congruencies in the findings of previous Spanish-language writing research and US-English e-mail writing research and then tested these hypotheses against a corpus of 107 Mexican business e-mails. I employed both a qualitative rhetorical analysis and a quantitative feature presence/absence analysis. Of the eight hypothesis statements describing Mexican business e-mails, only two were affirmed. The hypothesis statements describing these workplace e-mail ...


Speed Metrics And Crash Risks: Statistical Assessment And Implications For Highway Safety Policy , Thomas Brooks Stout Jan 2005

Speed Metrics And Crash Risks: Statistical Assessment And Implications For Highway Safety Policy , Thomas Brooks Stout

Retrospective Theses and Dissertations

This dissertation explores the relationships between measures of crash occurrence, the crash rate and the crash density, and various parameters of speed distributions as measured utilizing automatic traffic recorders (ATR) on highways in Iowa, with special attention to the implications of the findings with regard to highway safety policies such as speed limits and their enforcement. The goal of the research was to determine if crash risk is more related to absolute speed or to some measure of variation of the speed distribution. Data on crashes were obtained from the Iowa DOT crash data base. Roadway segments were selected utilizing ...


Competition Between Chimpanzees And Humans Over Fruit Of Saba Senegalensis In Southeastern Senegal, Michel Tyler Waller Jan 2005

Competition Between Chimpanzees And Humans Over Fruit Of Saba Senegalensis In Southeastern Senegal, Michel Tyler Waller

Retrospective Theses and Dissertations

Western chimpanzees (Pan troglodytes verus) compete directly with humans for a variety of wild growing plants in the Tomboronkoto region of southeastern Senegal. Due to political, economic, and demographic factors, the number of people collecting the fruit of the Saba senegalensis vine, an important food for chimpanzees and humans at a time of limited food diversity, is increa ing at a rate that may not be sustainable (Knutsen 2003). For humans, the fruit represents a much needed source of income at a time when crop stores are depleted and new crops have yet to produce. Often collected by women, the ...


Investment In The Stock Market And Value-Added Agricultural Businesses As Portfolio Investment Alternatives To Farm Expansion, Joshua David Roe Jan 2005

Investment In The Stock Market And Value-Added Agricultural Businesses As Portfolio Investment Alternatives To Farm Expansion, Joshua David Roe

Retrospective Theses and Dissertations

In the past decade, farmers have increasingly invested in value-added agriculture. Analysis of these investments compared to farm expansion by farmers was conducted from a portfolio optimization standpoint. Farms with similar investment patterns were identified by cluster analysis. When individual farm characteristics were analyzed to determine how these attributes affected investment choices, clear influences were found. In general, value-added agricultural investments were found to be an efficient investment alternative to farm expansion. Because of their larger risk, stock market investments play a smaller role in an optimized producer portfolio.


The Effects Of Trade Related Aspects Of Intellectual Property Rights On Developing Countries, Michael Yeboah Jan 2005

The Effects Of Trade Related Aspects Of Intellectual Property Rights On Developing Countries, Michael Yeboah

Retrospective Theses and Dissertations

An important hallmark of the 1994 Uruguay round of trade talks was the inclusion of the protection of the intellectual property rights across international borders by the WTO. This piece of legislation has helped put pressure on countries to reduce piracy in goods such as computer software. Yet it has had unintended adverse effect on developing countries especially the least developed countries. This paper uses price discrimination among countries as a way of solving lack of access to essential patented goods such as pharmaceuticals. One of the goals of World Trade organization (WTO) is to accelerate economic development in developing ...
