Incisal Dental Microwear Of The Prehistoric Point Hope Communities: A Dietary And Cultural Synthesis, Kristin L. Krueger Dec 2006

Incisal Dental Microwear Of The Prehistoric Point Hope Communities: A Dietary And Cultural Synthesis, Kristin L. Krueger

Master's Theses

The prehistoric coastal communities of Point Hope, Alaska have been considered important Arctic archaeological sites since their initial excavations in 1939. The majority of the archaeological artifacts are grouped into two temporally distinct cultural components, the Ipiutak (2100-1500BP) and the Tigara (800-300BP). Although debated, Arctic archaeologists have suggested that the Ipiutak depended heavily on land mammals with only seasonal reliance on sea mammals, whereas the Tigara relied primarily on sea mammals including whales. While both groups clearly utilized foraging subsistence economies, the contrasts in their food acquisition strategies would have placed different demands on the males and females, particularly with ...


Expression And Characterization Of Hyperthermophilic Aqujfex Pyrophilus Flagellin Protein In Mesophilic Bacterial Systems, Srivani V. Mukkamala Dec 2006

Expression And Characterization Of Hyperthermophilic Aqujfex Pyrophilus Flagellin Protein In Mesophilic Bacterial Systems, Srivani V. Mukkamala

Master's Theses

The structural protein flagellin, FlaA derived from hyperthermophilic Aquifex pyrophilus, a rod shaped eubacterial species that grows near hydrothermal vents at an optimum growth temperature of 85 °C forms elongated thermostable flagella nanotubes. FlaA was successfully over-expressed for the first time using pET28c plasmid in E. coli BL21 cells at 37 °C. The protein was isolated from inclusion bodies that were solubilized by alkaline pH, refolded by dialysis and purified by chromatographic techniques. The FlaA was characterized by fluorescence, light scattering and circular dichroism. The FlaA was not in the correct folded form to form flagella as efforts to form ...

Synthesis And Characterization Of Inosamines, Sing Raj Gurung

Master's Theses

This project is concerned with the preparation of scyllo-inosarnine hydrochloride 6, a biologically active compound, which bears six successive stereogenic centers. The synthesis of this compound would help elucidate the involvement of inosamines in biological nitrogen fixation. myo-Inositol served as the starting material to synthesize target compound 6. Regioselective protection and deprotection of myo-inositol provided azide 43 as key intermediate. In the final steps deprotection of five benzyl groups and reduction of azido group was achieved by catalytic hydrogenation. scyllo-Inosamine hydrochloride 6 was fully characterized by m.p., 1H NMR, 13C NMR, IR, EA and ...


The Analysis Of Ceramic Symbolism From The First Street Site In Barbados, Aya Hashimoto Dec 2006

The Analysis Of Ceramic Symbolism From The First Street Site In Barbados, Aya Hashimoto

Master's Theses

The expression of race and racism in material culture is of increasing interest in historical archaeology ( e.g., Epperson 1990, 1999, 2000; Mullins 1996, 1999). This study investigates 6 ceramic sherds from one vessel associated with a white urban domestic site on First Street, in Holetown Barbados. This vessel conveys a racist message. A black slave in a loincloth serving tea to a white person is transfer printed on the ceramic. The ceramic seems to be an annular designed pearlware from England in the first half of the 19th century.

By interpreting the meanings of the ceramic decoration, this ...

Metabolic And Phenotypic Characterization Of Aerobic Pcb Degrading Bacteria Isolated From Kalamazoo River Sediments, Brenton K. Lehmkuhl Dec 2006

Metabolic And Phenotypic Characterization Of Aerobic Pcb Degrading Bacteria Isolated From Kalamazoo River Sediments, Brenton K. Lehmkuhl

Master's Theses

The Kalamazoo River is contaminated with polychlorinated biphenyls (PCBs) which are neurotoxins and suspected carcinogens. The goal of this study was to isolate, identify, and metabolically characterize PCB degrading strains of aerobic bacteria. Biphenyl enrichments resulted in the isolation of putative PCB degrading strains from different locations along the river. Based on 16S rRNA gene analysis the isolated strains were identified as belonging to the genera of Achromobacter, Acidovorax, Cellulosimicrobium, Paenibacillus, Pseudomonas, and Rhodococcus. These strains were screened for their PCB degrading ability and congener specificity. All of the isolated strains degraded PCBs via the 2,3-dioxygenase pathway. The range ...

A Quantitative Analysis Of Morphological Changes In Specific Laminae Of The Olfactory Bulb Of Adult Zebrafish Following Peripheral Sensory Deafferentation, Travis L. Devlin

Master's Theses

Permanent removal of the olfactory organ in adult zebrafish has been shown to result in a significant reduction in the total volume of the ipsilateral olfactory bulb. The overall objective of the current project was to investigate the hypothesis that contact between the axons of the olfactory sensory neurons and the olfactory bulb is necessary for the maintenance of the normal post-synaptic organization of the olfactory bulb by quantifying the morphological changes that take place within specific laminae of the olfactory bulb following peripheral deafferentation. Complete, unilateral ablation of the olfactory organ resulted in permanent deafferentation of the ipsilateral olfactory ...

Determinants And Consequences Of Workers’ Remittances, Carlos Ivan Vargas-Silva Dec 2006

Determinants And Consequences Of Workers’ Remittances, Carlos Ivan Vargas-Silva

Dissertations

In this dissertation we study the determinants and consequences of workers' remittances. It is important for developing countries to have a clear understanding of the motivations that migrants have to remit money home, in order to increase remittances inflows. It is also important to understand the impact of remittances in the receiving countries in order to develop policies that can maximize the benefits of remittances, while minimizing any possible detrimental effects. In this dissertation we concentrate on the relationship between remittances and macroeconomic variables in the receiving countries. To this end we use both individual and aggregate level data.

Funding Michigan K-12 Educational Adequacy Without Rewarding Inefficiency, James J. Walters Dec 2006

Funding Michigan K-12 Educational Adequacy Without Rewarding Inefficiency, James J. Walters

Dissertations

Resource equalization represents the historical and theoretical basis for American school finance and its ideals continue to dominate discussion and practice. During the last decade and a half, the national aspiration for equitable distribution of school finance resources has started a transformation into a derivative notion of adequacy. This equity policy derivative embraces the idea of sufficiency, which in turn implies a standard. The concept of educational adequacy has grown to mean the achievement of high absolute standards. Equity (equalization) theorists measure resource level on a relative basis; each student relative to all others. Adequacy adherents measure student achievement against ...

An ABCA (and sometimes ABCDA), multiple baseline across individuals design was utilized in the study. The dependent variable under investigation was the percentage of safe lifting components. Following baseline measures, nursing staff participated in an information phase during which they reviewed and discussed components of safe patient transfers. A video scoring phase was introduced, during which, participants viewed and scored a model video of a patienttransfer ...


New Tests Of Univariate Symmetry Based On The Gini Mean Difference, Hend Ouda Dec 2006

New Tests Of Univariate Symmetry Based On The Gini Mean Difference, Hend Ouda

Dissertations

Gini mean difference (GMD) was proposed as a measure of income inequality by Corrado Gini in 1912. Since then it has been widely applied - mostly in theeconomics, but also in statistical and social science research.

Four statistical tests of univariate symmetry are being proposed---all based on the comparison of variation below and above the median (known or estimated) measured by the GMD. These tests are applicable to the data from populations with median known and unknown, and each of them has its rank-basedcounterpart, so they can also be used for ordinal data.

A Monte Carlo simulation study was performed to ...

A sample of students participated in post-test interview sessions designed to examine in depth their ...


Essays On The Latin American Foreign Exchange Market, Isabel Ruiz Dec 2006

Essays On The Latin American Foreign Exchange Market, Isabel Ruiz

Dissertations

During the last decade, Latin American countries have moved towards becoming more open and financially integrated. At the same time, the region has appeared to adopt a "bipolar" position concerning exchange rate regimes. Most countries have moved towards more flexible exchange rates, while others have implemented hard pegs in the form of dollarization. This dissertation has two goals. First, to measure linkages and dynamics across Latin American foreign exchange markets. Second, to explore how exchange rate uncertainty impacts U.S. foreign direct investment (FDI) into Latin America.

In order to study interactions among these markets, I focus on the level ...


Religion And Semiosphere: From Religious To The Secular And Beyond, Rajka Rush Dec 2006

Religion And Semiosphere: From Religious To The Secular And Beyond, Rajka Rush

Dissertations

Religion is a system of structural ideas that involve the natural ability of the mind to engage itself into the process of unlimited semiosis which can be defined as an existential openness of one's consciousness to the universe as a system. This primary religious consciousness becomes limited by language, symbolic, and cultural constraints. The religious semiotic space is a sub-cultural system open to culturally and cross-culturally encoded idioms and concepts. These cultural potentials are interpreted and settled by the religious exegesis expressed in the behavioral patterns of the symbolic actions that reflect a specific worldview of the closed community ...


Success In The First Year: Impact Of Alternative Advising On Students At A Liberal Arts College, James E. Swanson Dec 2006

Success In The First Year: Impact Of Alternative Advising On Students At A Liberal Arts College, James E. Swanson

Dissertations

Small faith-based liberal arts institutions are increasingly focused on recruitment and retention because it is critical to their existence. Because these institutions are completely enrollment driven, the numbers of students who persist through to their second year of college is a necessary administrative focus. Scholars have found that interactions between students and members of the institution, especially faculty, are critical to student persistence during the first year of College. Research has also demonstrated that academic advising plays an important role in first-year student persistence. A question remains, however, whether students are retained because of time spent with faculty or because ...


Decision Support Systems In Product Development: A Batesian Network Approach For Injection-Molded Products, Jason S. Trahan Dec 2006

Decision Support Systems In Product Development: A Batesian Network Approach For Injection-Molded Products, Jason S. Trahan

Dissertations

Attribute defects cause a majority of the scrap for many manufacturers injection-molding aesthetic parts, yet these defects receive little attention duringproduct development. Methods for preventing attribute defects have been hampered by the inability to quantify complex cause-effect relationships. However, the qualities of a burgeoning branch of knowledge-based systems, called Bayesian networks, have benefited various fields faced with similar circumstances.Bayesian networks have the capability of presenting causal relationships between variables in a graphical structure and quantitatively explaining their effects throughout that structure. These effects can be characterized by probabilities derived from sources, such as equations, historical data, rules-of-thumb or expert ...


Refocusing On Adult Probation: Theory Versus Practice, Paul David Gregory Dec 2006

Refocusing On Adult Probation: Theory Versus Practice, Paul David Gregory

Dissertations

This dissertation is a case study of an adult probation department in a southern state. Adult probation is an important part of the criminal justice system, as it provides a reduced program cost compared with incarceration. Current literature proposes that adult probation is in crisis due to poor to sub-standard performance by probationers, a collapse in supervision, and decline in probation funding. This dissertation attempts to answer the question of possible causes for problems in the adult probation system. To accomplish this, this work focuses on how probation officers and clients are affected by contradictions occurring between the theory and ...


Determining The Probability Of The Visual Detection Of Sink Marks On Differently Textured Injection Molded Products, Kurt Frederick Hayden Dec 2006

Determining The Probability Of The Visual Detection Of Sink Marks On Differently Textured Injection Molded Products, Kurt Frederick Hayden

Dissertations

The injection molding segment of the plastics industry has historically exhibited an environment of intense competition. To remain competitive, manufacturers must ensure that molds will produce defect-free parts without multiple design revisions. Designers often use computer simulations to predict design problems before the construction of tooling. These sophisticated software applications will soon have the ability to simulate the final appearance of products. However, the effects of aesthetic defects such as sink marks and splay are often difficult to simulate accurately and effectively.

It is understood that surface textures can conceal minor aesthetic defects. A well-known example is the concealment of ...

Counselor Education And Peace Building: Current Status And Future Direction, Jenny Ritha Keller Dec 2006

Counselor Education And Peace Building: Current Status And Future Direction, Jenny Ritha Keller

Dissertations

Counseling professionals are informed and guided in professional development, research and practice by the relevant professional organizations that endorse the field’s professional, ethical, and competency standards. Amidst the contemporary professional proclamations of multicultural- and social justice counseling as professional grounding principles, is also the directive to promote and engage in peace building. Although the notion of peace building appear to be conceptually congruent with the multicultural and social justice counseling competencies; peace building concepts and issues, and research on nonviolence, reconciliation, democratization, and conflict transformation, are as yet unchartered notions in the counselor education literature.

The purpose of this ...


Problem-Based Learning: An Attitudinal Study Of Police Academy Students, Gregory P. Vander Kooi Dec 2006

Problem-Based Learning: An Attitudinal Study Of Police Academy Students, Gregory P. Vander Kooi

Dissertations

Policing strategies have gravitated toward a consensus paradigm model, commonly referred to as "community policing." This is a significant paradigm shift, yet most police academies continue to use traditional lecture-based pedagogical methods to train police officers. One possible alternative to passive lecture-based teaching is a more active problem-based learning. Problem-based methodologies consist of presenting ill-structured problems whereby an instructor facilitates and directs the students in active inquiry toward possible solutions for a specific problem.

The Cover-Up Is More Damaging Than The Sin: Sexual Scandals At The Cabinet And Sub-Cabinet Levels, Craig Korpela Dec 2006

The Cover-Up Is More Damaging Than The Sin: Sexual Scandals At The Cabinet And Sub-Cabinet Levels, Craig Korpela

Dissertations

Based on the sexual scandals of Alexander Hamilton, John Eaton, Sumner Welles, and the recently concluded investigation of Henry Cisneros, this research provides an initial, and subsequently revised, set of phases and factors that describe sex scandals of Cabinet and sub-Cabinet secretaries. Garnered from these historical cases and other scandal literature are factors that impact the development of a sex scandal. Presidential support, traits of the indiscretion, relationships between executives, public opinion, legal matters, Congressional oversight, and efforts to cover-up a sexual affair are just a few of the factors that could impact the tenure of an appointee.
