  Citation × Citation Citation Abstract Copy Title: Understanding the Formation of Kinetically Stable Compounds and the Development of Thin Film Pair Distribution Function Analysis Author: Wood, Suzannah Year: 2017 Navigating the synthesis landscape poses many challenges when developing novel solid state materials. Advancements in both synthesis and characterization are necessary to facilitate the targeting of specific materials. This dissertation discusses the formation of chalcogenide heterostructures and their properties in the first part and the development of thin film pair distribution function analysis (tfPDF) in the second part. The heterostructures were formed by the self-assembly of designed precursors deposited by physical vapor deposition in a modulated elemental reactants approach, which provides the control and predictability to synthesis. Specifically, a series of (BiSe)1+δ(TiSe2)n, where n = 2,3,&4, were synthesized to explore the extent of charge transfer from the BiSe to TiSe2 layers. To further explore the role Bi plays in charge donation, a family of structurally similar compounds, (BixSn1-xSe)1+TiSe2 , where 0≥x≥1, were synthesized and characterized. Electrical measurements show doping efficiency decreases as x increases, correlated with the structural distortion and the formation of periodic antiphase boundaries containing Bi-Bi pairs. The first heterostructures composed of three unique structural types were synthesized and Bi2Se3 layer thickness was used to tune electrical properties and further explore charge transfer. To better understand the potential energy landscape on which these kinetically stable compounds exist, two investigations were undertaken. The first was a study of the formation and subsequent decomposition of [(BiSe)1+δ]n(TiSe2)n compounds, where n= 2&3, the second an investigation of precursor structure for thermodynamically stable FeSb2 and kinetically stable FeSb3. The second section describes the development of thin film pair distribution function analysis, a technique in which total scattering data for pair distribution function (PDF) analysis is obtained from thin films, suitable for local structure analysis. This study illustrates how analysis of the local structure in amorphous precursor films can help to understand the crystallization processes of metastable phases and enables a range of new local structure studies of thin films. tfPDF was then demonstrated on In-Ga-O film materials and compared to traditional powder PDF analysis. This highlights differences between the products, and the utility of tfPDF to determined structural features of amorphous materials. This dissertation includes previously published and unpublished co-authored materials.

  Citation × Citation Citation Abstract Copy Title: PATTERNS OF MORPHOSYNTACTIC AND FUNCTIONAL DIVERSIFICATION IN THE USAGE OF COGNATE VERBS IN INDO-IRANIAN Author: Shirtz, Shahar Year: 2017 This is a study of processes of structural and functional diversification of the uses of three cognate verbs across the Indo-Iranian language family: “do/make”, “be/become”, and “give”. First, this study identifies over sixty distinct construction types in which these verbs are used, including complex predicate constructions, nominal predication constructions, serial verb constructions, and several distinct auxiliary constructions. Since the sets of verbs studied here are cognates, and share a common source, crosslinguistic differences in their uses are the result of grammatical change, and especially shared and parallel innovations of similar uses. Then, this study presents a taxonomy of different complex predication types with “do/make”, and shows that there are general patterns in the deployment of different types of complex predication to express different types of situations. These patterns exhibit “transitivity prominence” previously identified by typologists with “heavy” or “lexical” verbs. This study then shows that these patterns are the result of several distinct pathways of grammatical change, often motivated by analogy to existing constructions, giving raise to different types of N-V complex predication constructions. Then, this study shows that despite the fact that Indo-Iranian speakers can potentially deploy distinct constructions to encode each of the six nominal predication functions, sets of such functions are often co-expressed by the same structural coding means, especially clauses with cognate “be/become” verbs. This study uses a novel method, based on bipartite network graphs, to compare of the degree to which nominal predication functions are co-expressed in different languages. Finally, this study shows that the three sets of cognate verbs are more likely to be used similarity within branches and subbranches of Indo-Iranian than across branches. The scope of this branches, however, is different for different verbs: “do/make” and “give” behave more similarly in languages which belong to the same major branch, Iranian or Indo-Aryan, but “be/become” clusters are at different levels of subbranching. This is the result of the different types of innovations attested with these verbs: reanalysis and actualization motivated by analogy with “do/make” and “give”, and metaphorical and metonymy extensions with “be/become”.

  Citation × Citation Citation Abstract Copy Title: Local Languages: The Forms of Speech in Contemporary Poetry Author: Fogarty, William Year: 2016 Robert Frost’s legendary description of “the sound of sense” to define his poetics has for decades sounded like little more than common sense. His idea is now taken to be fairly straightforward: the inflections of an utterance resulting from the tension between demotic speech and poetic form indicate its purport. However, our accepted notion of Frost’s formulation as simply the marriage of form and meaning misconstrues what is potentially revolutionary in it: if everyday speech and verse form generate tension, then Frost has described a method for mediating between reality, represented by speech, and art, represented by verse form. The merger is not passive: the sound of sense occurs when Frost “drag[s] and break[s] the intonation across the metre.” And yet Frost places speech and verse form in a working relationship. It is the argument of this dissertation that poets reckon with what is often understood as discord between poetry and reality by putting into correspondence forms of speech and the forms of poetry. The poets I examine–Seamus Heaney, Gwendolyn Brooks, Tony Harrison, and Lucille Clifton–are concerned with their positions in local communities that range from the family unit to ethnic, religious, racial, economic, and sexual groups, and they marshal forms of speech in poetic form to speak from those locales and to counter the drag and break of those located social and political realities. They utilize what I call their “local languages”–the speech of their particular communities that situates them geographically in local contexts and politically in social constructs–in various ways: they employ them as raw material; they thematize them; they invent idiosyncratic “local” languages to undermine expectations about the communities that speak those languages; they devise generalized languages out of standard and nonstandard constructions to speak not just to and from specific locations but to speak more broadly about human experience. How, these poets ask, can poetry respond to atrocities, deprivations, divisions, and disturbances without becoming programmatic or propagandistic and without reinforcing false preconceptions about the kinds of language suitable for poetry? They answer that question with the living speech of their immediate worlds.

  Citation × Citation Citation Abstract Copy Title: Structure-Stabilizing RNA Modifications Prevent MBNL Binding to Toxic CUG and CCUG Repeat RNA in Myotonic Dystrophy Author: Delorimier, Elaine Year: 2015 Myotonic dystrophy is a genetic neurodegenerative disease caused by repeat expansion mutations. Myotonic dystrophy type 1 (DM1) is caused by a CTG repeat expansion in the 3’ UTR of the dystrophia myotonia protein kinase (DMPK) gene, while myotonic dystrophy type 2 (DM2) is caused by a CCTG repeat expansion in intron 1 of the zinc finger protein nine (Znf9) gene. When expressed, these genes produce long CUG/CCUG repeat RNAs that bind and sequester a family of RNA-binding proteins known as muscleblind-like 1, 2 and 3 (MBNL1, MBNL2, MBNL3). Sequestration of these proteins plays a prominent role in pathogenicity in myotonic dystrophy. MBNL proteins regulate alternative splicing, and myotonic dystrophy symptoms are a result of mis-spliced transcripts that MBNL proteins regulate. MBNL proteins bind to a consensus sequence YGCY (Y = pyrimidine), which is found in CUG and CCUG repeats, and cellular RNA substrates that MBNL proteins bind and regulate. CUG and CCUG repeats can form A-form helices, however it is hypothesized that MBNL proteins bind to the helices when they are open and the YGCY binding site is single-stranded in nature. To evaluate this hypothesis, we used structure-stabilizing RNA modifications pseudouridine (Ψ) and 2’-O-methylation to determine if stabilization of CUG and CCUG repeat helices affected MBNL1 binding and toxicity. We also used Ψ to determine if the structure-stabilizing modification affected MBNL binding to single-stranded YGCY RNA. CUG repeats modified with Ψ or 2’-O-methyl groups exhibited enhanced structural stability and reduced affinity for MBNL1. Ψ also stabilized the structure of CCUG repeats and rigidified single-stranded YGCY RNA and inhibited MBNL1 binding to both of these RNAs. Binding data from CCUG repeats and single-stranded YGCY RNA suggest that both pyrimidines in the YGCY motif must be modified for significant inhibition. Molecular dynamics and X-ray crystallography suggest a potential water-bridging mechanism for Ψ-mediated CUG repeat stabilization. Molecular dynamics simulations suggest that Ψ increases base-stacking interactions, and reducing the flexibility of single-stranded RNA leads to reduced MBNL1 binding. Ψ modification rescued mis-splicing in a cellular DM1 model and prevented CUG repeat toxicity in zebrafish embryos. This dissertation includes previously published and unpublished coauthored material.

  Citation × Citation Citation Abstract Copy Title: Stability, Reactivity, and Constituent Interaction in TiSe2-Based Metastable Misfit Layer Compounds Synthesized from Designed Amorphous Precursors Author: Merrill, Devin Year: 2016 A series of intergrowth compounds with the basic formula [(MSe)1+δ]m(TiSe2)n are reported. The compounds are prepared from modulated elemental reactants and display interesting structural and electronic behavior. Section 1 of this dissertation outlines initial attempts to characterize constituent interaction. The first member of the SnSe based subclass is reported and displays the highest Seebeck coefficient of any m = n = 1 compound reported to date, and a surprising amount of order is observed, compared to previously reported compounds. With properly established deposition parameters, the synthesis was extended to included the m = 2-4 compounds. These compounds display interesting electronic behavior that suggests the band structure shifts considerably as the SnSe block is expanded, affecting the interaction between the constituent layers. The first compound based on BiSe is then reported, suggesting that the Bi structure donates more conduction electrons to the band structure. Targeted substitution through kinetic control is the focus of Section 2, and a family of (PbxSn1-xSe)1+δTiSe2 is reported over the entire range of x, even though a miscibility gap exists in the bulk PbxSn1-xSe system. The resulting alloyed intergrowth compounds also display equal or higher mobility than the end members, suggesting modulation doping could be used to affect transport properties. As a proof of principle, the analogous system based on a BixSn1-xSe constituent was prepared to attempt to systematically affect carrier concentration. It was found that while carrier concentration can be controlled, the evolving structure affects the doping efficiency of the Bi atoms and mobility in the structure. Section 3 outlines attempts to form higher order TiSe2-based heterostructures and the important chemical considerations observed during the preparation of these materials. The 3 component systems in the Pb-Sn-Ti-Se system can be formed at low temperature, with SnSe2 rather than SnSe. While at higher temperatures, topotactic reactions occur, causing rearrangement to the alloyed rocksalt structure. Compounds within the alloy system with m > 1 are presented which show surface segregation of Pb atoms, and a designed experiment suggests this is a thermodynamic effect. This dissertation includes previously published and unpublished coauthored material.

  Citation × Citation Citation Abstract Copy Title: The Axiology of Necrologies: Using Natural Language Processing to Examine Values in Obituaries Author: Levernier, Jacob Year: 2017 This dissertation is centrally concerned with exploring obituaries as repositories of values. Obituaries are a publicly-available natural language source that are variably written for members of communities that are wide (nation-level) and narrow (city-level, or at the level of specific groups therein). Because they are explicitly summative, limited in size, and written for consumption by a public audience, obituaries may be expected to express concisely the aspects of their subjects' lives that the authors (often family members living in the same communities) found most salient or worthy of featuring. 140,599 obituaries nested in 832 newspapers from across the USA were scraped with permission from *Legacy.com,* an obituaries publisher. Obituaries were coded for the age at death and gender (female/male) of the deceased using automated algorithms. For each publishing newspaper, county-level median income, educational achievement (operationalized as percent of the population with a Bachelor's degree or higher), and race and ethnicity were averaged across counties, weighting by population size. A Neo4J graph database was constructed using WordNet and the University of South Florida Free Association Norms datasets. Each word in each obituary in the corpus was lemmatized. The shortest path through the WordNet graph from each lemma to 30 Schwartz value prototype words published by Bardi, Calogero, and Mullen (2008) was then recorded. From these path lengths, a new measure, "word-by-hop," was calculated for each Schwartz value to reflect the relative lexical distance between each obituary and that Schwartz value. Of the Schwartz values, Power, Conformity, and Security were most indicated in the corpus, while Universalism, Hedonism, and Stimulation were least indicated. A series of nine two-level regression models suggested that, across Schwartz values, newspaper community accounted for the greatest amount of word-by-hop variability in the corpus. The best-fitting model indicated a small, negative effect of female status across Schwartz values. Unexpectedly, Hedonism and Conformity, which had conceptually opposite prototype words, were highly correlated, possibly indicating that obituary authors "compensate" for describing the deceased in a hedonistic way by concurrently emphasizing restraint. Future research could usefully further expand word-by-hop and incorporate individual-level covariates that match the newspaper-level covariates used here.

  Citation × Citation Citation Abstract Copy Title: Latino History Is Oregon History: Preserving Oregon’s Latino Heritage through the Pineros y Campesinos Unidos del Noroeste Archive Author: de la Cruz, Sonia, Stephanie, David Kays, Woken Year: 2017, 2016 Since the spring of 2011, the University of Oregon Libraries have been working closely with the Pineros y Campesinos Unidos del Noroeste (Northwest Tree Planters and Farmworkers United, PCUN) to organize, preserve, and make accessible to the public the extensive records they have generated during their history. A union of largely Latino farmworkers based in Oregon’s fertile Willamette Valley, PCUN is the largest organization representing Oregon’s growing Latino population. As in many other states, the state’s Latino community is growing so rapidly that, as of the 2010 census, Latinos constitute Oregon’s largest ethnic minority. Since 1985, PCUN has been a fierce advocate of the rights of farmworkers, 98 percent of whom are Latino. Engaged faculty at the University of Oregon have worked closely with PCUN over the years, advancing research and social justice through intellectual and activist collaboration. As PCUN has matured as an organization, it has increasingly recognized the need to preserve its own story, both for the institution’s future and as a contribution to Oregon’s Latino community. For its part, the University of Oregon (UO), as the flagship public university of the state of Oregon, has acknowledged the importance of recognizing and serving all segments of Oregon’s diverse population. This convergence of interests led to the agreement between PCUN and the UO, signed in June of 2011, to house and make accessible to the public PCUN’s records. Since that time, faculty, students, and staff at the UO Libraries have been working to organize and advocate for this important collection. Drawing on a network of engaged scholars, community activists, and skilled librarians, the PCUN records have been a nucleus for projects to ensure that UO truly serves all of the people of Oregon, and that the state’s history does not marginalize its Latino community.

Since that time, faculty, students, and staff at the UO Libraries have been working to organize and advocate for this important collection. Drawing on a network of engaged scholars, community activists, and skilled librarians, the PCUN records have been a nucleus for projects to ensure that UO truly serves all of the people of Oregon, and that the state’s history does not marginalize its Latino community.
