Paraprofessionals Who Work With Elementary Grade Students With Significant Disabilities In Inclusive Settings, Regina Moreno

Dissertations and Theses

The use of paraprofessional services is an established and crucial aspect in the pursuit of a free and appropriate public education for students with disabilities. Paraprofessionals are often the primary providers of instruction for students with severe disabilities yet are the least trained instructional personnel in schools. Identified competencies and necessary training content for paraprofessionals who serve students with severe disabilities are nearly absent in the professional literature.

This study extended the current literature regarding paraprofessionals who serve students with disabilities in public schools by focusing specifically on those paraprofessionals who serve students with severe disabilities in inclusive general education …

Demonstrating Sustainable Farm Management Systems. Final Report For Rcg05-Ord13, Tara Slaven, Francis Bright, Jodie Hawley, Joe Sherrard

Natural resources research reports

The Ord River Irrigation Area (ORIA) has a 'flow through' irrigation system. That is, irrigation water is diverted from Lake Kununurra and any waste water from the irrigation system and farms flows directly back into the river downstream. This means that any sediment, nutrient or chemicals in tailwater from farms flows straight into the river.

The Ord Land and Water Management Plan 2000 specifies goals to improve surface water quality. The goals are to reduce the load of chemical and nutrient contamination and sediment in tailwater by 40 per cent.

The aim of this project was to develop and demonstrate …

Report On Polyacrylamide, A Practice To Reduce Sediment And Insoluable Chemicals In Tailwater, Tara Slaven

Bulletins 4000 -

The main barrier to the adoption of PAM seems to the timing of the cost of outlay. This could add significantly to the initial crop establishment costs at a time of year when rowers receive no income. However, the partial and parametric analysis indicates that there re benefits from using PAM as part of the crop management cycle. These benefits are from ving water, retaining sediment on-farm and reducing the cost of delving drains. There are ther potential economic benefits including the retainment of phosphorus as a plant nutrient n-farm and subsequent yield increases.

Additionally, the off-site environmental impacts seem …

A 'Ho New World: Raced And Gendered Insult As Ersatz Carnival And The Corruption Of Freedom Of Expression Norms, Lolita Buckner Inniss

Publications

Carnivalization, a concept developed by literary theorist Mikhail Bakhtin and later employed in broad social and cultural contexts, is the tearing down of social norms, the elimination of boundaries, and the inversion of established hierarchies. It is the world turned upside down. Ersatz carnival is a pernicious, inverted form of carnival, one wherein counter-discourses propounded by outsiders are appropriated by elites and frequently redeployed to silence and exclude those same outsiders. The use of the slur "'ho" by gangsta' rappers in the performance of songs that articulate a vision of urban culture is an example of carnivalization. Thus, when words …

When Income Matters: Customers Evaluation Of Shopping Malls' Hedonic And Utilitarian Orientations, Thomas Allard, Barry J. Babin, Jean-Charles Chebat

Research Collection Lee Kong Chian School Of Business

This study, based on 772 shopper's interviews in two shopping malls, establishes that malls can achieve differentiation from their competitors through the pursuit of singular orientations following the hedonic and utilitarian dimensions of shopping. Furthermore, perceived differentiation from competitors is found to positively influence customers’ attachment to the mall, a determining factor in the mall's evaluation. Interestingly, mall's orientation related to hedonic elements was found appealing by all subjects, although slightly more by those with lower income. However, utilitarian orientation appeared strictly effective on those with higher income. Theoretical and managerial implications along with limitations are discussed.

Rethinking Consideration In The Electronic Age, Robert A. Hillman, Maureen A. O'Rourke

Faculty Scholarship

Our fast-paced age of electronic agreements that ostensibly govern transactions as diverse as downloading software, ordering goods, and engaging in collaborative development projects raises questions regarding thesuitability of contract law as the appropriate legal framework. While this question arises in many settings, we focus here on the free and open source software (FOSS) movement because of the maturity and success of its model and the ubiquity of its software. We explore in particular whether open source licenses are supported by consideration, and argue that they are, and that open source licenses are contracts. We further argue that a contractual framework …

Sensitivity Analysis Framework For Large And Complex Simulation Models, Ghaith Rabadi, Shannon Bowling, Charles Keating, Resit Unal

Engineering Management & Systems Engineering Faculty Publications

In this paper, a framework for conducting Sensitivity Analysis (SA) on large and complex simulation models is introduced. The framework consists of components that are designed to make the SA a systematic process that is easy to manage and follow by simulation analysts and practitioners. Unlike local SA (one-variable-at-a-time SA), the method presented here is variance-based and it is rooted in the field of Design of Experiments (DoE) where Input Variables are varied and Output Variables are measured. Based on the DoE results, a risk scoring system is developed to identify the sensitivity of the Input Variables, and as a …

Computer-Aided Reasoning About Knowledge And Justifications, Natalia Novak

Dissertations, Theses, and Capstone Projects

In the first Chapter we compare two well-known type-based computer frameworks for computer aided logical reasoning and verification: MetaPRL and Coq. In particular, we implement in MetaPRL the Calculus of Inductive Constructions which is the theoretical base for Coq. This work has shown the common points of MetaPRL and Coq, and revealed their principal methodological differences. A possible application of this work is a possibility to perform re-validation in MetaPRL of the existing library of Coq proofs which could help to build more trust in the latter.

Chapter 2 is the main contribution of the dissertation. It contains the description …

Beyond Observation: Literature And Science In Kafka, Rilke, Mann And Musil, Katya Ilina

Dissertations, Theses, and Capstone Projects

The relationship between science and literature is an expanding area of scholarly interest which remains underrepresented within the field of Germanistik. This dissertation will attempt to close the gap by focusing on the interactions between the selected works of Franz Kafka, Rainer Maria Rilke, Thomas Mann, and Robert Musil, and the scientific outlooks which began to emerge in the nineteenth century primarily by focusing on the concept of observation. Observation is a concept important for the period of my investigation because it signified a major shift in consciousness. The prior facile division into impartial experimenter and observed phenomenon, so characteristic …

Anger Et Cetera: Understanding The Emotions In Ethics, Damien Dupont

Dissertations, Theses, and Capstone Projects

This dissertation argues in part that because the ethical theory of sentimentalism is based on the mistaken belief that emotions are non-cognitive, sentimentalism cannot account for the fact of the influence of cognition in morality and moral action. Therefore sentimentalism is of little use in ethics.

This work is done by going back to examine Western thinking on the emotions from its dawn in Homer's writing through to contemporary philosophy and neurophysiology on the emotions. Following the development of the way emotions were thought of and how they related to ethics allows the identification of an intellectual forked path brought …

"Reconnecting To Resilience" A Historical Study Of Slave Narratives With Implications For Social Work Practice With African American Youth From High Risk Environments, Barbara E. Milton Ii

Dissertations, Theses, and Capstone Projects

The often times high risk environment of African American youth negatively impacts their psychological well being, their family relations and community connections. Many African American youth today are experiencing the vestiges of historical trauma that took root in America in the 17th Century when the first Africans came to America. As a result of generational transmission of historical trauma, many youths today are disproportionately underachieving in education, disproportionately poor, disproportionately monitored by police and incarcerated and disproportionately disrespected by the society at large. In order to reduce the disparity of contemporary problems effecting African American youth, social scientists need to …

Youth In Out-Of-Home Care: The Question Of Psychological Agency, Lauren M. Polvere

Dissertations, Theses, and Capstone Projects

This dissertation examines the critical perspectives of formerly institutionalized youth with psychiatric disabilities through the lens of psychological agency. Framed in sociohistorical perspective, a theoretical shift is suggested for understanding the development of youth with mental health placement histories. In contrast to clinical approaches, which focus on psychopathology of youth in placement, this study elucidates the agentic meaning making processes employed by youth as they negotiate various treatment contexts and engage in activism. Participants in the study are 12 youth between the ages of 16-23, who are involved in peer-run groups for young people with out-of-home treatment experience, and 4 …

Biodegradation Of Fuel Oxygenates In Northeastern United States Aquifers With An Analysis Of Underground Storage Tank Leaks, Gordon Hinshalwood

Dissertations, Theses, and Capstone Projects

During the past decade the application of monitored natural attenuation has become one of the predominant technologies used in the remediation of gasoline spills impacting subsurface soils and groundwater. The success of this method has depended, for the most part, on the biodegradation of those gasoline constituents that dissolve into groundwater and transport with the groundwater most readily.

One of the most mobile components of gasoline formulations during the past 20 years has been methyl tertiary butyl ether (MTBE), which has traditionally been viewed in both the scientific and the regulatory communities as relatively recalcitrant to biodegradation. However, cases of …

"A Kind Of Construction In Light And Shade": An Analytical Dialogue With Recording Studio Aesthetics In Two Songs By Led Zeppelin, Aaron Liu-Rosenbaum

Dissertations, Theses, and Capstone Projects

This dissertation examines how the sound of a recording contributes meaning to the song, working in conjunction with the song’s lyrics, harmonic and rhythmic structures, album artwork, and within its cultural context. Two songs by the rock group Led Zeppelin, “When the Levee Breaks” and “Stairway to Heaven,” are taken as analytical examples in which special attention is paid to the acoustic properties of the recordings, that is, where the instruments are situated within the stereo sound field; how they are timbrally manipulated with effects such as reverb, echo, distortion, and chorus; their relative levels of prominence; and how these …

Invertebrate Colonization And Plant Architecture: The Influence Of Two Non-Native Milfoil Species, Elizabeth W. Rielly

Theses and Dissertations

The purpose of this study was to determine if the complexity and surface area of a macrophyte’s

structure has an influence on invertebrate colonization, and to determine the influence of two non-native species on invertebrate colonization. Three plant architectures were compared. Floating leaved plants were represented by the following species: Nuphar lutea, Nymphaea odorata, and Brasenia schreberi. Moderately dissected leaved plants were represented by Potamogeton natans, and highly dissected leaved plants were represented by two non-native species, Myriophyllum spicatum and Myriophyllum heterophyllum. The number of invertebrates/g dry biomass and the number of individuals/m², diversity, evenness, and richness were calculated for …

Potential Export Of Unattached Benthic Macroalgae To The Deep Sea Through Wind Driven Langmuir Circulation, H. M. Dierssen, Richard C. Zimmerman, Lisa A. Drake, David J. Burdige

OES Faculty Publications

Carbon export to the deep sea is conventionally attributed to the sinking of open ocean phytoplankton. Here, we report a Langmuir supercell event driven by high winds across the shallow Great Bahama Bank that organized benthic non-attached macroalgae, Colpomenia sp., into visible windrows on the seafloor. Ocean color satellite imagery obtained before and after the windrows revealed a 588 km² patch that rapidly shifted from highly productive macroalgae to bare sand. We assess a number of possible fates for this macroalgae and contend that this event potentially transported negatively buoyant macroalgae to the deep Tongue of the Ocean …

Influence Of Irradiance And Iron On The Growth Of Colonial Phaeocystic Antarctica: Implications For Seasonal Bloom Dynamics In The Ross Sea, Antarctica, Nathan S. Garcia, Peter N. Sedwick, Giacomo R. Ditullio

OES Faculty Publications

Laboratory culture experiments were used to investigate the growth rate of colonial Phaeocystis anarctica as a function of irradiance and dissolved iron concentration. The experiments were conducted with a P. antarctica strain isolated from the southern Ross Sea, Antarctica, and made use of natural, low-iron (P. antarctica attained an average maximum cell-specific growth rate of 0.37 d^-1at an irradiance of 68 μE m^-2s^-1, above which growth rates decreased to 0.27 d^-1 at an irradiance of 314 μE m^-2s^-1. The dependence of growth rate on ambient dissolved iron concentration was …

Anthropogenic Osmium In Rain And Snow Reveals Global-Scale Atmospheric Contamination, Cynthia Chen, Peter N. Sedwick, Mukul Sharma

OES Faculty Publications

Osmium is one of the rarer elements in seawater, with typical concentration of ≈10 x 10^-15 g g^-1 ( 5.3 x 10^-14 mol kg^-1. The osmium isotope composition (¹⁸⁷Os/¹⁸⁸Os ratio) of deep oceans is 1.05, reflecting a balance between inputs from continental crust (≈ 1.3) and mantle/cosmic dust (≈ 0.13). Here, we show that the ¹⁸⁷Os/¹⁸⁸Os ratios measured in rain and snow collected around the world range from 0.16 to 0.48, much lower than expected (>1), but similar to the isotope composition of ores (approximate to 0.2) …
