Pattern-Responsive Lexicon Optimization
No full textIn this paper, we show that current interpretations of Lexicon Optimization (Prince and Smolensky 1993), in particular that of Archiphonemic Underspecification (Inkelas 1995), incorrectly predict the distribution of underspecification in lexical entries. We present cases from three vowel harmony languages in which speakers treat harmonic and disharmonic roots differently under reduplication. The assumption of full specification entails a ranking paradox, which can be resolved if underspecification is admitted in certain contexts not predicted by the principles of Lexicon Optimization. We point the way towards an expanded model of Lexicon Optimization that would both allow for and predict such cases of underspecification.The definitive version of this paper was published in NELS 30: Proceedings of the North East Linguistic Society 30 (2000) and is available at http://glsa.hypermart.net/cgi-bin/list.cgi?NELS%NELS30%5%NFunding for fieldwork was provided by the International Research and Exchanges Board (IREX).Harrison, David K. & Kaun A.

When Languages Die: The Extinction Of The World\u27s Languages And The Erosion Of Human Knowledge
No full textIn When Languages Die, K. David Harrison illustrates the individual face of language loss, as well as its global scale. Languages are the accretion of thousands of years of a people\u27s science and art - from observations of ecological patterns to creation myths. The author shows that the disappearance of a language is a loss not only for the community of speakers itself but also for our common human knowledge of mathematics, biology, geography, philosophy, agriculture, and linguistics. In this century, we face a massive erosion of the human knowledge base. The global abandonment of indigenous languages will bring a massive loss of accumulated knowledge and culture - this book argues for the irreplaceable nature of these unique knowledge systems and the urgency of documenting them before they are lost forever
An Investigation into the Impact of Mission Statements on School Development Planning.
No full textThis thesis uses quantitative as well as qualitative methods to examine the impact of school philosophical statements on school development planning.
Three case study schools from an Asian city were selected. A questionnaire and face to face interviews were used as data gathering tools. The data from the questionnaires informed the questions created for the interviews and the outcomes of these two data sources were analysed qualitatively. As a result of the findings from qualitative analysis a further quantitative analysis was made of the questionnaire data. A total of 188 responses to questionnaires were examined and 22 interviews took place.
The main aim of this research is to empirically examine the assumptions that underpin the Council of International Schools and New England Association of Schools and College’s accreditation standards for school philosophical statements and development planning. At the heart of these assumptions is the belief that school development planning is most effective when it is closely linked to a clearly written, collaboratively created set of philosophical statements which articulate the school’s values and beliefs. To date this assumption has not been substantiated by research. A secondary aim is to examine the systems and structures in schools that assist in linking the school’s philosophy to its planning processes.
The data resulted in a set of interesting findings. Firstly, insights were gained into techniques used to reaffirm and embed school philosophy into the school’s culture. Secondly, the data suggested that the assumptions made by the accrediting agencies hold true under certain circumstances but that a school’s underlying ideology may be more powerful in driving institutional planning. As a result of the findings, suggestions to further develop accreditation standards are made and ideas for further research are proposed
The choral music of Lou Harrison. (Volumes I and II)
No full textLou Harrison's music is clearly an important contribution to the twentieth century repertoire. His early writing for percussion ensemble, experiments in just intonation, melding of Eastern and Western influences, instrument building, and music for gamelan are especially significant. While much of his work has received attention, performance, and praise, his music for chorus is not well-known, much of it in manuscript and inaccessible.This study examines in detail the complete choral works of Harrison from 1939 to the present. It is the purpose of the study to define his compositional style through an analysis of these works. The text is divided into three main sections, the first of which is a brief biography and chronology of the choral works. The main body of the document is an analysis of the works, discussed in chronological order. Each piece is addressed individually with regard to the stylistic characteristics of melody, rhythm, harmony, texture, form, and text setting, where applicable. The final portion is a summary of Harrison's compositional style for chorus and concluding remarks. Appendices include a chronological listing of the works, and transcriptions of conversations between the author and Lou Harrison and Ben Johnston and Harrison. The second volume contains reproductions of the unpublished choral scores.Harrison's background has furnished a rich and fertile soil for the development of his choral style. His early study with Henry Cowell and Arnold Schoenberg, associations with John Cage and Harry Partch, and abiding affinity to Eastern cultural, philosophical, and musical influences, coupled with an adherence to the principles of just intonation and interest in the world's music, has produced a willful experimentation with and assimilation of various styles within his own. All of these influences are clearly evident in the choral works, music which is expressive, fresh, imaginative, and interesting, an amalgam of his many loves and interests.U of I OnlyETDs are only available to UIUC Users without author permissio
Identification and characterization of critical laminin-111 sequences required for polymerization and cell surface anchorage and the requirement of both activities for proper basement membrane formation and other events
No full textA system was developed for expression and purification of various recombinant a1 LG4-5 and heterotrimeric laminin-111 proteins. A number of combinations involving different promoters, 5’UTRs, signal sequences, epitope tags, selectable antibiotics, and purification schemes were tested in order to optimize the system. A homology model of laminin a1 LG4-5 was generated and utilized to identify candidates for mutation and expression as recombinant a1 LG4-5 proteins. The crystal structure of a1 LG4-5 was also determined. Heparin, a-dystroglycan (aDG), and sulfatide binding of the generated mutants demonstrated wide differences and dependence upon contributions from basic residues on the surface of LG4, including: RKR2721 and KRK2793 for heparin; RAR2833, KDR2860, the Asn2811 glycation moiety, and the LG4 Ca2+ ion for aDG; the LG4 Ca2+, Arg2833 of RAR2833, and Lys2766 residue of RKGRTK2770 for one sulfatide binding site, and the Arg2831 of RAR2833 for a second sulfatide site. The produced recombinant heterotrimeric laminin-111s demonstrated a requirement for the N-terminal LN domains of laminin-111’s constituent a1, b1, and g1 chains in self-polymerization. The inability of embryoid bodies, derived from laminin g1 null embryonic stem cells, to express Lm-111 and develop past formation of an outer endodermal layer of cells without laminin, was utilized via the addition of exogeneous recombinant laminin-111s, to test the various functions of the recombinant laminins and their ability to form a basement membrane and induce both differentiation of an epiblast layer and formation of a central cavity. Laminins’ containing defective polymerization or a1 LG4 anchorage failed to form a BM or undergo any further development after endodermal differentiation. Experiments with Schwann cells, C2C12 myotubes, and mouse embryonic fibroblasts demonstrated the requirement for both polymerization and a1 LG4 mediated anchorage in laminin-111 for proper BM formation, cytoskeletal attachment, and laminin induced cell signaling via Src. The results also suggest a role for laminin-111 polymerization and anchorage in providing a means for aggregation and accumulation of low affinity interactions in a complex, thereby attaining very high net affinities for binding interactions and attaining otherwise unatainable thresholds necessary for these interactions to exert their effects through manipulation of the cytoskeleton, as well as, laminin induced differentiation and cell signaling.Ph.

Mechanical design, calibration, and environmental protection of the REXIS DAM
No full textThesis: S.M., Massachusetts Institute of Technology, Department of Mechanical Engineering, 2013.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 167-172).The REgolith X-ray Imaging Spectrometer (REXIS) is a joint effort by MIT and Harvard to build the student-collaboration experiment aboard OSIRIS-Rex, an asteroid sample return mission sponsored by the NASA New Frontiers program. OSIRISREx is scheduled to launch to near-Earth asteroid Bennu in 2016. REXIS is a coded-mask imaging X-ray spectrometer that supports the missions scientific goals by globally and spatially mapping the soft X-ray emission spectrum of Bennu. X-rays corresponding to unique elements are fluoresced from the asteroid by incident solar radiation and enter the instrument through a coded-aperture mask composed of a psuedorandom pinhole pattern. The X-rays that pass through the mask strike an array of four charge-coupled devices (CCDs) that detect the incident photon energy and location on the imaging array. A spatial map of selected elemental abundances on Bennu is constructed by cross-correlating the mask pattern with the collected data. The CCDs are integrated into a Detector Assembly Mount (DAM) that serves three critical functions: Mechanical alignment, calibration and protection of the CCDs. In this thesis we outline the overall design of the REXIS DAM with a focus on its three main functions. Chapter 1 provides background on the OSIRIS-REx mission and the REXIS instrument. Chapter 2 discusses the adaptation of the AXAF CCD Imaging Spectrometer (ACIS) focal plane mechanical design and X-ray Imaging Spectrometer (XIS) flexprint electrical design for the REXIS DAM. Chapter 3 outlines the heritage of the DAM internal calibration sources from XIS and the MIT MicroX project. Driving science and engineering considerations for a calibration scheme are described and then used to inform the mechanical design of a novel calibration set for the REXIS DAM. Chapter 4 illustrates the need for protection from the space environment and analyzes the specific risks to the detectors and DAM in space. Special coatings and a one-time deployable radiation shield are used to protect the assembly and ensure integrity of REXIS science data. Chapter 5 describes the test performed to validate the CCD alignment scheme and the dynamic model of the radiation cover. Chapter 6 summarizes the key results of the present work and outlines plans for future work on the DAM.by Harrison L. Bralower.S.M
Scaling up coral restoration using innovative Symbiodinium co‐culture and mass larval supply on reefs
No full textThis report provides details of the research and outcomes from the Great Barrier Reef Innovation Challenge Proof of Concept 2019-20120 Research Project TF6.7.7 ‘Scaling up coral restoration using innovative Symbiodinium co‐culture and mass larval supply on reefs’. This project is a collaboration between Professor Peter Harrison (Southern Cross University, Lismore), Katie Chartrand (James Cook University, Cairns), Associate Professor David Suggett (University of Technology, Sydney) with Aroona Boat Charters (Ross Miller) and Reef Magic Cruises (Eric Fisher). During the project we also further developed active partnership networks with Citizens of the GBR, Biopixel, local Yirrganydji and Gunggandji Land and Sea Rangers, and other small businesses in the Cairns region, enabled by a GBRMPA research permit.
The aim of the project is to further develop innovative methods for scaling up coral restoration by mass culturing reef coral larvae and Symbiodiniaceae microalgal photosymbionts, co‐culturing larvae and photosymbionts, and enhancing larval supply on damaged reefs to significantly increase the settlement and recruitment success of juvenile corals. Additional objectives include expanding the use of LIFT‐FRRf fluorometry for diagnosing ‘desired’ types of heat‐tolerant Symbiodiniaceae and quantifying photosynthetic performance, and expanding partnerships with local reef tourism operators, Traditional Owners and media groups
