A New Gravitational Approach to Least Transportation Cost Warehouse Location
The purpose of this study is to examine single facility warehouse location models. The need for such a study is primarily two-fold. First, single facility warehouse location models which determine an alleged optimum location through a coordinate system have been developed. Secondly, the need for additional research is necessary because the approaches involving linear programming, simulation, or heuristic programming do not by definition generate an optimal location. digital.library.unt.edu/ark:/67531/metadc164418/
A New Literary Realism: Artistic Renderings of Ethnicity, Identity, and Sexuality in the Narratives of Philip Roth
Access: Use of this item is restricted to the UNT Community.
This dissertation explores Goodbye, Columbus and Five Short Stories (1959), the Ghost Writer (1979), the Counterlife (1986), the Facts (1988), Operation Shylock (1993), Sabbath's Theater (1995),and the Human Stain (2000), arguing that Roth relishes the telling of the story and the search for self within that telling. with attention to narrative technique and its relation to issues surrounding reality and identity, Roth's narratives stress unreliability, causing Roth to create characters searching for a more complex interpretation of self. Chapter I examines Roth’s negotiation of dual identities as Neil Klugman in Goodbye, Columbus feels alienated and displaced from Christianized America. the search for identity and the merging of American Christianity and Judaism remain a focus in Chapter II, which explores the implications of how, in the Ghost Writer, a young Nathan Zuckerman visits his mentor E.I. Lonoff to find him living in what he believes to be a non-Jewish environment—the American wilderness. Chapter II also examines the difficulties of cultural assimilation in "Eli, the Fanatic," in which Eli must shed outward appearances of Judaism to fit into the mostly Protestant community of Woodenton. Relative to the negotiation of multiple identities, Chapter III considers Sabbath’s attempt, in Sabbath’s Theater, to reconcile his spiritual and physical self when seeking to avoid his inevitable death. Exploring a further dimension of the search for self, Chapter IV traces the legacy of stereotyped notions of identity, considering ways in which Roth subverts stereotypes in the Human Stain. the search for identity and its particular truths remains a focus of Chapter V, which explores Roth's creation of an unstable reality through the Counterlife, the Facts, Operation Shylock, and the Human Stain, suggesting that the literary imagination matters more than truth in fiction. in its attention to Roth's focus on identity, race, and narrative technique, this dissertation contributes to the evolution of criticism addressing the social significance of the major works of Philip Roth. digital.library.unt.edu/ark:/67531/metadc115092/

New Mexico Climate Change Advisory Group Final Report
Recognizing the profound implications that global warming and climate variation could have on the economy, environment and quality of life in the Southwest, New Mexico Governor Bill Richardson signed Executive Order 05-33 on June 5th, 2005, establishing the New Mexico Climate Change Advisory Group. The Governor directed the CCAG to prepare a report that includes a projection of the State's future GHG emissions and policy recommendations for reducing New Mexico's total greenhouse gas emissions to 2000 levels by the year 2012, 10 percent below 2000 levels by 2020 and 75 percent by 2050. digital.library.unt.edu/ark:/67531/metadc226598/
A New N-way Reconfigurable Data Cache Architecture for Embedded Systems
Access: Use of this item is restricted to the UNT Community.
Performance and power consumption are most important issues while designing embedded systems. Several studies have shown that cache memory consumes about 50% of the total power in these systems. Thus, the architecture of the cache governs both performance and power usage of embedded systems. A new N-way reconfigurable data cache is proposed especially for embedded systems. This thesis explores the issues and design considerations involved in designing a reconfigurable cache. The proposed reconfigurable data cache architecture can be configured as direct-mapped, two-way, or four-way set associative using a mode selector. The module has been designed and simulated in Xilinx ISE 9.1i and ModelSim SE 6.3e using the Verilog hardware description language. digital.library.unt.edu/ark:/67531/metadc12079/
New Organized Crime: Problems and Issues for Information Analysis
This study illustrates the changing nature of organized crime at both national and international levels. Organized crime groups have changed in that they have entered the realm of high technology. In response this change, the use of new or modified analytical tools is suggested to enhance law enforcement efforts. This study highlights the problems of, and offers particular solutions for information analysis in its use in the fight against organized crime. Ultimately, it is argued that combined crime and intelligence analysis can be an effective and efficient method for the detection and prevention of modern organized crime. digital.library.unt.edu/ark:/67531/metadc2907/
New Reality Resembles Old: An Examination of the American Public's Social Construction of Reality Following September 11, 2001 Terrorist Attacks
This thesis examines whether the September 11, 2001 terrorist attacks caused a significant, lasting change in the American public's social construction of reality. A framework of everyday reality was created which focused on beliefs, behaviors, and cultural institutions in the United States. Data regarding specific beliefs and behaviors was collected from numerous survey sources, and content analysis was performed on media literature from September 11, 2001 to September 11, 2003. Findings from this study show that beliefs examined did change, while behaviors on similar topics did not. These finding represents an interesting paradox to be evaluated in future studies. Cultural institutions, as related to the public's knowledge of and relationship with each, also appeared little changed. Therefore, while some aspects displayed adjustment, this study cannot conclusively state that American public's social construction of reality experienced a "new reality" paradigm shift as proclaimed by the media immediately following the attacks. digital.library.unt.edu/ark:/67531/metadc4481/
New Resources in Twentieth-Century Piano Music and Richard Wilson's Eclogue (1974)
This dissertation draws some of the innovative composers from the early 1900's to the 1960's into the spotlight to highlight their new musical and pianistic ideas. These composers, including Debussy, Schoenberg, Webern, Bartók, Cowell and others, brought new creative forces into piano music, generating many distinctive features of modern music. The discussion of new resources in harmonic language, timbre, texture, form and concept of time has a direct bearing on aspects of Richard Wilson's Eclogue itself as well as aspects of performance problems. American Composer, Richard Wilson, has written three substantial piano solo works, Eclogue, Fixations, and Intercalations. Eclogue, from 1974, is a one-movement work. The detailed analysis of Eclogue covers aspects of form, harmonic language, timbre and texture, and rhythm and time. In addition, essential issues of performance problems such as notation, rhythmic control, extended techniques, hands distribution, and pedaling are also discussed. digital.library.unt.edu/ark:/67531/metadc2632/

New Shades of Clown White: a Study of Selected Comic Pantomimists in Europe and America 1920-1970
This thesis is neither a textbook of pantomime, with instructions for the development of mimetic expertise, nor a history of pantomime. What is recorded here is the personal philosophy of the art of pantomime advanced by Jean-Louis Barrault, Étienne Decroux, Charlie Chaplin, Marcel Marceau, and Red Skelton. The section devoted to each artist contains the portions of his biography pertaining to his development as a mime and a representative sample of critical reactions to his work. In addition to this purpose, this thesis also offers evidence that the comic style of pantomime underwent a change in nature in its use by the mimes who are studied here. Whereas the comic style was original! y unique to pantomimes that had no other intent but to produce laughter or, at most, pathos by physical comedy, these mimes took the comic pantomime into the realms of introspection and philosophy. digital.library.unt.edu/ark:/67531/metadc164020/
New Source of Natural Fertilizer Discovered in Oceans

New Surveillance Technologies and the Invasion of Privacy Rights
Access: Use of this item is restricted to the UNT Community.
Definition of privacy has changed by the changes and improvements in information and surveillance technologies. These changes and improvement need new legal decisions for new kinds of privacy invasions. This study explores the scope of privacy right, particularly when a technological surveillance has occurred by law enforcement agencies. It focuses in particular on increasing law enforcements' surveillance technologies and devices that have the potential to impact citizens' information privacy. These increasing changes in surveillance technologies have important implications both for law enforcements and citizens. This study also discusses increasing law enforcement surveillance for the public's security, changes of the laws that allow law enforcements to use new surveillance powers as a war on terrorism, and the citizens concerns of information privacy. A particular attention is given to the recent public opinion surveys which show citizens' increasing privacy concerns. Finally, a set of recommendations to figure out security-privacy debate and reduce the privacy concerns of the citizens is offered. digital.library.unt.edu/ark:/67531/metadc4252/
A New Wireless Sensor Node Design for Program Isolation and Power Flexibility
Over-the-air programming systems for wireless sensor networks have drawbacks that stem from fundamental limitations in the hardware used in current sensor nodes. Also, advances in technology make it feasible to use capacitors as the sole energy storage mechanism for sensor nodes using energy harvesting, but most current designs require additional electronics. These two considerations led to the design of a new sensor node. A microcontroller was chosen that meets the Popek and Goldberg virtualization requirements. The hardware design for this new sensor node is presented, as well as a preliminary operating system. The prototypes are tested, and demonstrated to be sustainable with a capacitor and solar panel. The issue of capacitor leakage is considered and measured. digital.library.unt.edu/ark:/67531/metadc28378/

News photography image retrieval practices: Locus of control in two contexts.
Access: Use of this item is restricted to the UNT Community.
This is the first known study to explore the image retrieval preferences of news photographers and news photo editors in work contexts. Survey participants (n=102) provided opinions regarding 11 photograph searching methods. The quantitative survey data were analyzed using descriptive statistics, while content analysis was used to evaluate the qualitative survey data. In addition, news photographers and news photo editors (n=11) participated in interviews. Data from the interviews were analyzed with phenomenography. The survey data demonstrated that most participants prefer searching by events taking place in the photograph, objects that exist in the photograph, photographer-provided keywords, and relevant metadata, such as the date the picture was taken. They also prefer browsing. Respondents had mixed opinions about searching by emotions elicited in a photograph, as well as the environmental conditions represented in a photograph. Participants' lowest-rated methods included color and light, lines and shapes, and depth, shadow, or perspective. They also expressed little interest in technical information about a photograph, such as shutter speed and aperture. Interview participants' opinions about the search methods reflected the survey respondents' views. They discussed other aspects of news photography as well, including the stories told by the pictures, technical concerns about digital photography, and digital archiving and preservation issues. These stated preferences for keyword searching, browsing, and photographer-provided keywords illustrate a desire for a strong internal locus of control in digital photograph archives. Such methods allow users more control over access to their photographs, while the methods deemed less favorable by survey participants offer less control. Participants believe they can best find their photographs if they can control how they index and search for them. Therefore, it would be useful to design online photograph archives that allow users to control representation and access. Future research possibilities include determining the preferences of other image retrieval system users, performing user studies with moving image information retrieval systems, and uniting content-based and concept-based image retrieval research. digital.library.unt.edu/ark:/67531/metadc5591/

Newspaper Ownership Structure and the Quality of Local Political News Coverage
This research sought to ascertain how newspaper ownership structures influence the quality of local political news coverage. More specifically, do independently owned newspapers tend to produce larger quantities of quality local political reporting than do corporately owned and publicly traded newspapers? In the thesis, I develop an understanding of "quality" news coverage as being coverage that is thematic, or providing interpretive analysis and supplying contextual information. Additionally, I tackle the question of quality news coverage from three angles: whether or not independently owned newspapers provide more quality local political news stories per edition than corporately owned papers; whether or not the percentage of quality local political news stories of total political news stories within an edition is higher for independently owned or corporately owned newspapers; and whether or not the percentage of total political news stories of total news stories is higher for independently owned or corporately owned newspapers. digital.library.unt.edu/ark:/67531/metadc115055/

Nicotinic Acetylcholine Receptor α3 mRNA in Rat Visual System After Monocular Deprivation
In situ hybridization was used to examine effects of monocular enucleation on nicotinic acetylcholine receptor subunit cc3 mRNA in the rat dLGNand visual cortex. After 28 days postoperative, there were no significant differences in α3 mRNA density between the contralateral (deprived) and ipsilateral (non-deprived) sides. The lack of obvious effects of visual deprivation on α3 mRNA density suggests that other factors, possibly intrinsic to dLGNand visual cortex, govern the postnatal expression of α3 mRNA. digital.library.unt.edu/ark:/67531/metadc278900/
The “Nigger Trinity”: Engaging the Discourse in Post Civil Rights/Post 1960s America
Access: Use of this item is restricted to the UNT Community.
The cultural and popular media landscape of the United States of America changed after the Civil-Rights movement of the 1960s. The word “Nigger” was changed during that same period of American history. There are several authors and a comic that helped change this word during the 1960s. The post Civil-Rights American has a different experience and understanding with this word than those born before 1970. This work triangulates the current cultural location of the word “Nigger,” “nigga,” and “the n-word” using linguistics, law, and two media case studies. The “Nigger” trinity is a model that adds value to the discourse that surrounds this one word in post civil-rights/post 1960s America. digital.library.unt.edu/ark:/67531/metadc103290/
Night of no Exile
Night of no Exile is a collection of poems preceded by a critical article entitled "‘Exile seems both a blessing and a curse': A Blissful Reading of Li-Young Lee's Poetry." That article discusses Lee's quest to achieve communication, truth, and transcendence through poetic language and concludes that he finally reaches his goal through a leap from narrative poetry to lyricism. The "exile" alluded to in the title of the article is not only geographic, but also interioran exile due to the natural limitations of all languages, and which can be bridged only in linguistic ways. Lee's solution to that problem (lyricism) turns his poetry into what Roland Barthes would call "a text of bliss," a text that manages to deeply destabilize language, while simultaneously achieving a new kind of meaning. In the main body of the manuscript, the first section contains short love lyrics. The second section, "Night of no Exile," is an attempt at the demanding genre of the longer lyric poem. The third section uses short lyrics to explore various topics, such as discovering one's identity, friendship and solidarity between women, family history, and childhood memories. Finally, the last section includes poems, four of them longer, attempting to combine narrative and lyric impulses in a way not unlike Li-Young Lee's experimentation with those two genres. digital.library.unt.edu/ark:/67531/metadc2217/
The Nightingale in Poetry and Music
Access: Use of this item is restricted to the UNT Community.
This thesis surveys a variety of songs and arias for high soprano which feature the nightingale; examines the musical elements that symbolize, refer to, or imitate the nightingale; and compares these musical elements with transcriptions of the nightingale's song. The first chapter reviews the symbolic development of the nightingale and its role in poetry and literature. The interior chapters address a selection of musical compositions that feature the nightingale and its song. The final chapter establishes a relationship between the sound of the actual sound of the nightingale and the musical gestures created by composers to imitate the nightingale. digital.library.unt.edu/ark:/67531/metadc4161/
The Nightingale's Flight from Opera to Symphonic Poem: A Comparative Study of The Nightingale and The Song of the Nightingale by Igor Stravinsky
An analysis of the transformation from Stravinsky's opera The Nightingale to The Song of the Nightingale, a symphonic poem by the same composer. The text includes a brief history of Stravinsky's life and the genesis of The Nightingale and The Song of the Nightingale. The bulk of the dissertation discusses actual changes employed by Stravinsky (with score examples). Patterns of modifications are identified and discussed as they relate to the composer's change of attitude in orchestration. The analysis focuses on overall patterns of alteration imposed by Stravinsky and their perceived effectiveness achieving a symphonic aural outcome. digital.library.unt.edu/ark:/67531/metadc2725/
Nihilism and the Formulation of a Philosophy of Art
Nihilism is often associated with feelings of despair, hopelessness and meaningless. It is certainly true that once the implications of this philosophy become apparent that these feelings are valid. However, this reaction is merely the first stage of dealing with nihilism and stopping here fails to examine the various types of nihilism that deal specifically with knowledge, ethics, metaphysics, truth, and art. Nihilism at its base is a philosophy that recognizes the history of human thought and what it means to be and to think. My focus is the way in which a completed nihilism is in fact an emancipatory act and the implications it has for art and the artist in the 21st century. digital.library.unt.edu/ark:/67531/metadc67991/

The Nineteenth Century Oboe Concertino: An Overview of its Structure with Two Performance Guides
Music written for oboe and orchestra in the nineteenth century falls into three categories: Classical Concerto, Opera Fantasy, and Concertino. The classical, or standard, three movement, sonata-ritornello format was only sparingly used. Instead, composers chose more the experimental forms of the Opera Fantasy and Concertino. The Opera Fantasy was used as a way for oboe players to play popular opera arias of the time, while showcasing their virtuosity and expression. It is in the Concertino where composers expanded the oboe repertoire to its highest form in the nineteenth century, experimenting with structure, and using the oboe to the height of its expressive powers. In addition to discussion on the Concertino in general, performance guides have been provided for two concertinos, Concertino for Oboe and Winds, by Carl Maria von Weber and Concertino for Oboe and Orchestra, Op. 18, by August Klughardt. Information is provided regarding composer biography, compositional/historical perspective, technical and stylistic considerations, and structure. By examining the two very different pieces, one from the beginning of the nineteenth century and one from the end, the evolution of the Concertino can be seen, as well as gaining an understanding of the wide variety of repertoire written for the oboe in the nineteenth century. digital.library.unt.edu/ark:/67531/metadc3225/
El Niño and health
El Niño Southern Oscillation (ENSO) is a climate event that originates in the Pacific Ocean but has wide-ranging consequences for weather around the world, and is especially associated with droughts and floods. The irregular occurrence of El Niño and La Niña events has implications for public health. On a global scale, the human effect of natural disasters increases during El Niño. The effect of ENSO on cholera risk in Bangladesh, and malaria epidemics in parts of South Asia and South America has been well established. The strongest evidence for an association between ENSO and disease is provided by time-series analysis with data series that include more than one event. Evidence for ENSO's effect on other mosquito-borne and rodent-borne diseases is weaker than that for malaria and cholera. Health planners are used to dealing with spatial risk concepts but have little experience with temporal risk management. ENSO and seasonal climate forecasts might offer the opportunity to target scarce resources for epidemic control and disaster preparedness. digital.library.unt.edu/ark:/67531/metadc226726/
Ninth grade student success: An analysis of a credit recovery program.
The purpose of the study was to determine the extent to which a credit recovery program improved the academic success for high school freshmen. For the purpose of this study, academic success was defined as whether or not the student advanced from 9th to 10th grade. A total of 255 students from two junior high schools and one comprehensive high school were included in the study. Independent variables included program, gender, ethnicity, socioeconomic status, TAKS Reading/Language Arts results, and TAKS Mathematics results. A review of related literature provided background information regarding the issues surrounding high school freshmen, dropouts, grade retention, and effective intervention programs. This quantitative study utilized descriptive statistics and logistic regression to analyze the relationship between the independent variables and student success as measured by whether or not the student advanced from ninth to tenth grade. In addition, the study examined the odds of success if participating in the credit recovery program. Sources of data included Incomplete and Failure Listing, Ninth Grade Advisor Listing, Tenth Grade Advisory Listing, and the Student Roster-Fall Collection. The Ninth Grade Success Initiative Program Evaluation for Cycles 6, 7, and 9 provided the individual student results of participation in the program. Levels of significance were set at the .05 level. The findings of this study indicated that no statistically significant relationship existed between participation in the credit recovery program, gender, ethnicity, socioeconomic status, TAKS Reading/Language Arts results, TAKS Mathematics results, and advancing from 9th to 10th grade. It was concluded that further study would be needed to determine the most effective means for providing academic assistance to ninth grade students. digital.library.unt.edu/ark:/67531/metadc4431/
Ninth-grade Students’ Negotiation Of Aesthetic, Efferent, And Critical Stances In Response To A Novel Set In Afghanistan
This qualitative, action research study was guided by two primary research questions. First, how do students negotiate aesthetic, efferent, and critical stances when reading a novel set in Afghanistan? Second, how do aesthetic and efferent stances contribute to or hinder the adoption of a critical stance? A large body of research exists that examines student responses to literature, and much of that research is based on the transactional theory of reading. However, it remains unclear how critical literacy fits into this theory. This study describes how one group of high school students’ aesthetic and efferent responses to a novel set in Afghanistan supported their development of critical stances. Six students enrolled in a ninth-grade English course participated in this study. Data were collected for 13 weeks. Data included two individual interviews with each student, student writing assignments in the form of 6 assigned journal entries and 7 assigned essays, transcriptions of 12 class discussions, field notes, lesson plans, a teacher researcher journal, and research memos. Data were analyzed using the constant comparative method. Three major findings emerged from this study. First, class discussions provided a context for students to adopt stances that were not evident in their individual written responses to the novel, which were completed prior to the discussions. Second, the discussions provided scaffolding that helped several of the students adopt world-efferent and critical stances. Third, both the aesthetic and the efferent stances contributed to students’ adoption of critical stances. digital.library.unt.edu/ark:/67531/metadc103398/

An NMR study of 2-ethyl-1-butyllithium and of 2-ethyl-1-butyllithium/lithium 2-ethyl-1-butoxide mixed aggregates
A 1H, 13C, and 6Li NMR study of 2-ethyl-1-butyllithium indicated that 2-ethyl-1-butyllithium exists only as a hexameric aggregate over the entire temperature range of 25 to - 92.1 ° C in cyclopentane. Reacting 2-ethyl-1-butyllithium with 2-ethyl-1-butanol resulted in alkyllithium/lithium alkoxide mixed aggregates, apparently of the form Ra(RO)bLia+b. A multinuclear, variable temperature NMR study of samples with O:Li ratios of 0.2 and 0.4 showed, in addition to the alkyllithium, the formation of four mixed aggregates, one of them probably an octamer. Higher O:Li ratio samples showed the formation of several other mixed aggregates. Mixing 2-ethyl-1-butyllithium with independently prepared lithium 2-ethyl-1-butoxide formed the same mixed aggregates formed by in situ synthesis of lithium alkoxide. Lithium 2-ethyl-1-butoxide also exists as aggregates in cyclopentane. digital.library.unt.edu/ark:/67531/metadc2807/
An NMR Study of 2-Ethylbutyllithium/Lithium 2-Ethyl-1-butoxide Mixed Aggregates, Lithium Hydride/Lithium 2-Ethyl-1-butoxide Mixed Aggregates, n-Pentyllithium Aggregates, and n-Pentyllithium/Lithium n-Pentoxide Mixed Aggregates
Access: Use of this item is restricted to the UNT Community.
A 13C and 6Li variable temperature NMR study of 2-ethylbutyllithium/lithium 2-ethyl-1-butoxide mixed aggregates formed from reacting 2-ethyl-1-butanol with 2-ethylbutyllithium in two O/Li ratios of 0.2/1 and 0.8/1. The 0.2/1 sample resulted in two 2-ethylbutyllithium/lithium 2-ethyl-1-butoxide mixed aggregates and seven lithium hydride/lithium 2-ethyl-1-butoxide mixed aggregates. The lithium hydride mixed aggregates were also studied using selective 1H decoupling experiments. The 0.8/1 sample resulted in six 2-ethylbutyllithium/lithium 2-ethyl-1-butoxide mixed aggregates and five lithium hydride/lithium 2-ethyl-1-butoxide mixed aggregates. A low temperature 13C NMR spectroscopy study of n-pentyllithium indicated three aggregates, most likely a hexamer, an octamer, and a nonamer. A low temperature 13C NMR study of an 0.2/1 O/Li ratio sample of n-pentyllithium mixed with 1-pentanol resulted in three n-pentyllithium/lithium n-pentoxide aggregates mixed aggregates along with the three n-pentyllithium aggregates. 13C NMR data for this mixture gave inconclusive results whether or not lithium hydride/lithium alkoxide mixed aggregates were present in the sample. digital.library.unt.edu/ark:/67531/metadc4906/
NMR study of 2-ethylhexyllithium aggregate and 2- ethylhexyllithium/lithium 2-ethyl-1-hexoxide mixed aggregates.
A 1H, 13C, and 6Li NMR study of 2-ethylhexyllithium showed that 2- ethylhexyllithium exists solely as a hexamer in cyclopentane solution over the temperature range from 25 to -65 °C. Furthermore, 2-ethylhexyllithium and lithium 2- ethyl-1-hexoxide were shown to form mixed aggregates when the alkoxide was formed in situ by reacting 2-ethylhexyllithium with 2-ethyl-1-hexanol. A multinuclear, variable temperature NMR study of a sample with an O:Li ratio of 0.2 led to the identification of at least four such aggregates, one of which was found to be a hexamer with the composition R5(RO)Li6. Studies of samples with higher O:Li ratios, up to 0.8, showed additional mixed aggregates present. All solutions containing mixed aggregates were also shown to contain hydrocarbon soluble lithium hydride. A study of lithium 2-ethyl-1- hexoxide indicated that it aggregates in solution as well. digital.library.unt.edu/ark:/67531/metadc3037/
NMR Study of n-Propyllithium Aggregates
A variable temperature 1H, 13C, and 6Li NMR study of n-propyl-6Li-lithium showed five different aggregates, similar to that in the literature as (RLi)n, n= 6, 8, 9, 9, 9. There were also a number of additional new species, identified as lithium hydride containing aggregates. Unexpectedly, a series of 13C{1H} 1-D NMR experiments with selective 6Li decoupling showed evidence for 13C-6Li spin-spin coupling between the previously reported (RLi)n aggregates and various hydride species. digital.library.unt.edu/ark:/67531/metadc3350/
An NMR Study of Trimethylsilylmethyllithium Aggregates and Mixed Trimethylsilylmethyllithium/Lithium trimethylsilylmethoxide Aggregates
Access: Use of this item is restricted to the UNT Community.
An NMR spectroscopy study of trimethylsilylmethyllilthium, TMSM-Li, indicates that TMSM-Li exists as two different aggregates in cyclopentane solution. Using previously reported colligative properties of TMSM-Li in different solutions in connection with new 13C and 6Li NMR data collected in this study, aggregation states were assigned as octamer and hexamer. Low temperature 13C and 6Li NMR peak intensities indicated an equilibrium exists between the two aggregates that shifts toward the octamer as the temperature decreases. ΔH was calculated to be 5.23 + 0.15 kcal/mol and ΔS was calculated to be 17.9 + 0.6 eu for the hexamer/octamer equilibrium system. Samples of TMSM-Li were mixed with TMSM-OH in attempts to form mixed alkyllithium/lithium alkoxide aggregates. 13C NMR data for these mixtures gave inconclusive results whether or not these compounds formed, which is different from other primary alkyllithium compounds studied in the past. A study of neopentyllithium, NpLi, indicates only one aggregate in solution with the aggregation state unknown using low temperature 13C NMR spectroscopy. digital.library.unt.edu/ark:/67531/metadc4657/
NNS Use of Adverbs in Academic Writing
Recent studies have begun to redefine the idea of accuracy in second language acquisition to include not only grammatical correctness, but also native-like selection. This is an exploratory study aimed at identifying areas of nonnative-like selection of adverbs, such as sentence position, semantic category preferences, frequency of use and breadth of word choice. Using corpus-linguistic methods it compares the writing of nonnative English speakers at an intermediate and advanced level to both American college students’ writing and published academic writing. It also conducts in-depth case studies of three of the most commonly used adverbs. It finds that while advanced students are grammatically accurate, there are still several ways in which their use of adverbs differs from that of native speakers. digital.library.unt.edu/ark:/67531/metadc84213/

No Fairy Godmothers: Essays on Life, Love, and Feminism
Heterosexual romance and marriage are institutionalized ideals in our society, set forth, in part, through the portrayal of stereotyped gender roles in fairy tales, such as Cinderella, and by the mainstream media. This thesis explores the cultural messages aimed at women, which impose the necessity of altering oneself to achieve marriage, and offers feminist viewpoints. Using the form of the personal essay, I discuss the ideals of Cinderella, Prince Charming, marriage, and Happily Ever After as unrealistic, though still prevalent, given the popularity of books like The Rules: Time-tested Secrets for Capturing the Heart of Mr. Right, and Princess Diana as Cinderella icon. Essays on my own experience of marriage and divorce supplement the cultural issues, juxtaposing the personal and political toward a new paradigm for relationships. digital.library.unt.edu/ark:/67531/metadc278569/
