Report To The Commissioner Of Soil Conservation On The Condition Of The Pastoral Resource Base 2010, Department Of Agriculture And Food, Western Australia Nov 2010

Report To The Commissioner Of Soil Conservation On The Condition Of The Pastoral Resource Base 2010, Department Of Agriculture And Food, Western Australia

Natural resources published reports

Western Australia’s rangelands cover 87% of the state and include all but the south west. Pastoral leases, used for grazing of livestock on native vegetation, cover 35% (874,000 km2) of the rangelands, with Unallocated Crown Lands (UCL) and lands vested for conservation and Indigenous purposes making up the balance. There are currently 459 registered pastoral stations (made up of 510 pastoral leases) in Western Australia; there are 159 stations in the Northern Rangelands (Kimberley and Pilbara), 291 stations in the Southern Rangelands, and nine stations in the South West Land Division.

Agent Sensing With Stateful Resources, Adam D. Eck Nov 2010

Agent Sensing With Stateful Resources, Adam D. Eck

School of Computing: Dissertations, Theses, and Student Research

In many real-world applications of multi-agent systems, agent reasoning suffers from bounded rationality caused by both limited resources and limited knowledge. When agent sensing also requires resource use, the agent’s knowledge revision is affected due to its inability to always sense when and as accurately as needed, further leading to poor decision making. In this research, we consider what happens when sensing activities require the use of stateful resources, which we define as resources whose state-dependent behavior changes over time based on usage. Specifically, sensing itself can change the state of a resource, and thus its behavior, which affects both …

Factors Influencing Teacher Job Satisfaction And Their Alignment With Current District Practices In A Rural School District, Taneal Marie Wallace Nov 2010

Factors Influencing Teacher Job Satisfaction And Their Alignment With Current District Practices In A Rural School District, Taneal Marie Wallace

Dissertations

School districts’ decisions across the country are influencing the satisfaction level of teachers, in both positive and negative ways. With statistics reporting as high as fifty percent of teachers leaving the profession in the first five years of experience (Ingersoll, 2003), determining the reasons for teacher dissatisfaction are important in correcting district practices to be more supportive and satisfying to teachers. The purpose of this research study was to (a) determine the satisfaction level of teachers in a specific school district, (b) determine the practices building-level administrators have put into place and how they relate to the factors identified in …

Act 4: How The Land Looks (C. 30,000 Bce-1984), James Smith Allen Nov 2010

Act 4: How The Land Looks (C. 30,000 Bce-1984), James Smith Allen

A Privileged Past

Act 4 of "A Privileged Past" shifts its focus from the author and his experiences to his wife, Anne Winston, and her family, especially on the high plains of Oklahoma and the Pacific shores of southern California. This woman’s parents were descended from tenacious farmers, circuit preachers, and committed teachers. Arising out of a dysfunctional family, however, Winston’s quest for control over her personal life was located in educational and professional achievement in German Studies before 1984. The dominant metaphor of this chapter concerns sight, a natural sensibility that the protagonist has sharpened over years with her acute visual memory.

Teaching Goals Of Interpreter Educators, Stephen Fitzmaurice Nov 2010

Teaching Goals Of Interpreter Educators, Stephen Fitzmaurice

International Journal of Interpreter Education

Angelo & Cross (1993) found substantial differences in the teaching goals of faculty from different disciplines, yet they found no differences for educators based on their employment status or the type of institution in which they worked. The current quantitative study compared the teaching goals of interpreter educators with those of educators from other disciplines. Respondents were asked to rate the importance of 52 goal statements from Angelo & Cross’ Teaching Goal Inventory (TGI) in terms of what they aim to have students accomplish in their courses. The data suggest that interpreter education constitutes a separate discipline from the nine …

Revealed Preferences For Risk And Ambiguity, Donald J. Brown, Chandra Erdman, Kirsten Ling, Laurie Santos Nov 2010

Revealed Preferences For Risk And Ambiguity, Donald J. Brown, Chandra Erdman, Kirsten Ling, Laurie Santos

Cowles Foundation Discussion Papers

We replicate the essentials of the Huettel et al. (2006) experiment on choice under uncertainty with 30 Yale undergraduates, where subjects make 200 pair-wise choices between risky and ambiguous lotteries. Inferences about the independence of economic preferences for risk and ambiguity are derived from estimation of a mixed logit model, where the choice probabilities are functions of two random effects: the proxies for risk-aversion and ambiguity-aversion. [Our principal empirical finding is that we cannot reject the null hypothesis that risk and ambiguity are independent in economic choice under uncertainty. This finding is consistent with the hypothesized independence of the neural …

Construction And Improvement Of A Scheffler Reflector And Thermal Storage Device, Jason Rapp Nov 2010

Construction And Improvement Of A Scheffler Reflector And Thermal Storage Device, Jason Rapp

Physics

We constructed and successfully tested a 2 m2 parabolic dish solar concentrator (Scheffler Concentrator) to focus sunlight onto a stationary target. Present efforts are to decrease the construction complexity and cost of the concentrator. In order to store solar heat, we also constructed and are testing a thermal storage device made of sand (for thermal mass), and pumice (for insulation). Preliminary tests indicate thermal retention times of many hours. Present efforts are to increase accessible power, and structural integrity.

Parity Detection In Quantum Optical Metrology Without Number-Resolving Detectors, William N. Plick, Petr M. Anisimov, Jonathan P. Dowling, Hwang Lee, Girish S. Agarwal Nov 2010

Parity Detection In Quantum Optical Metrology Without Number-Resolving Detectors, William N. Plick, Petr M. Anisimov, Jonathan P. Dowling, Hwang Lee, Girish S. Agarwal

Faculty Publications

We present a method for directly obtaining the parity of a Gaussian state of light without recourse to photon-number counting. The scheme uses only a simple balanced homodyne technique and intensity correlation. Thus interferometric schemes utilizing coherent or squeezed light and parity detection may be practically implemented for an arbitrary photon flux. Specifically, we investigate a two-mode, squeezed light, Mach-Zehnder interferometer and show how the parity of the output state may be obtained. We also show that the detection may be described independently of the parity operator and that this 'parity-by-proxy' measurement has the same signal as traditional parity. © …

On The Point Behavior Of Fourier Series And Conjugate Series, Ricardo Estrada, Jasson Vindas Nov 2010

On The Point Behavior Of Fourier Series And Conjugate Series, Ricardo Estrada, Jasson Vindas

Faculty Publications

We investigate the point behavior of periodic functions and Schwartz distributions when the Fourier series and the conjugate series are both Abel summable at a point. In particular we show that if f is a bounded function and its Fourier series and conjugate series are Abel summable to values γand β at the point θ0, respectively, then the primitive of f is differentiable at θ0, with derivative equal to γ, the conjugate function satisfies limθ?θ0 3(θ-θ0)3R θθ0̃ f(t) (θ - t)2 dt = β, and the Fourier series and the conjugate series are both (C, κ) summable at θ0, for …

The Not-So-Quiet Revolution: Cautionary Comments On The Rejection Of Hypothesis Testing In Favor Of A “Causal” Modeling Alternative, Daniel H. Robinson, Joel R. Levin Nov 2010

The Not-So-Quiet Revolution: Cautionary Comments On The Rejection Of Hypothesis Testing In Favor Of A “Causal” Modeling Alternative, Daniel H. Robinson, Joel R. Levin

Journal of Modern Applied Statistical Methods

Rodgers (2010) recently applauded a revolution involving the increased use of statistical modeling techniques. It is argued that such use may have a downside, citing empirical evidence in educational psychology that modeling techniques are often applied in cross-sectional, correlational studies to produce unjustified causal conclusions and prescriptive statements.

Notes On Hypothesis Testing Under A Single-Stage Design In Phase Ii Trial, Kung-Jong Lui Nov 2010

Notes On Hypothesis Testing Under A Single-Stage Design In Phase Ii Trial, Kung-Jong Lui

Journal of Modern Applied Statistical Methods

A primary objective of a phase II trial is to determine future development is warranted for a new treatment based on whether it has sufficient activity against a specified type of tumor. Limitations exist in the commonly-used hypothesis setting and the standard test procedure for a phase II trial. This study reformats the hypothesis setting to mirror the clinical decision process in practice. Under the proposed hypothesis setting, the critical points and the minimum required sample size for a desired power of finding a superior treatment at a given α -level are presented. An example is provided to illustrate how …

Adjusted Confidence Interval For The Population Median Of The Exponential Distribution, Moustafa Omar Ahmed Abu-Shawiesh Nov 2010

Adjusted Confidence Interval For The Population Median Of The Exponential Distribution, Moustafa Omar Ahmed Abu-Shawiesh

Journal of Modern Applied Statistical Methods

The median confidence interval is useful for one parameter families, such as the exponential distribution, and it may not need to be adjusted if censored observations are present. In this article, two estimators for the median of the exponential distribution, MD, are considered and compared based on the sample median and the maximum likelihood method. The first estimator is the sample median, MD1, and the second estimator is the maximum likelihood estimator of the median, MDMLE. Both estimators are used to propose a modified confidence interval for the population median of the exponential distribution, MD …

A Comparison Between Unbiased Ridge And Least Squares Regression Methods Using Simulation Technique, Mowafaq M. Al-Kassab, Omar Q. Qwaider Nov 2010

A Comparison Between Unbiased Ridge And Least Squares Regression Methods Using Simulation Technique, Mowafaq M. Al-Kassab, Omar Q. Qwaider

Journal of Modern Applied Statistical Methods

The parameters of the multiple linear regression are estimated using least squares ( B̂LS ) and unbiased ridge regression methods (B̂(KI,J)). Data was created for fourteen independent variables with four different values of correlation between these variables using Monte Carlo techniques. The above methods were compared using the mean squares error criterion. Results show that the unbiased ridge method is preferable to the least squares method.

Extending The Rit-Dupont Suprathreshold Data Set: Weighted Individual Discrimination Pair Data And New Chroma Dependency Visual Data, Bingxin Hou Nov 2010

Extending The Rit-Dupont Suprathreshold Data Set: Weighted Individual Discrimination Pair Data And New Chroma Dependency Visual Data, Bingxin Hou

Theses

Since the 1980's, the RIT-DuPont dataset has been used extensively for color-difference formula development and testing. In the past, the dataset was published as 156 color median tolerances along specific vector directions about 19 color centers. The median tolerance, referred to as T50, is the estimated absolute magnitude of the color difference at which 50% of the population will accept or reject a pair relative to an anchor pair. 1D Probit analysis, a univariate statistical technique that locates a median threshold from a binary response data, was used to transform judgments of 958 color-difference pairs by 50 observers to 156 …

Loring-Greenough House, North Yard Archaeogeophysics, Jamaica Plain, Massachusetts, John M. Steinberg, Christa M. Beranek, John Schoenfelder, Kathryn A. Catlin Nov 2010

Loring-Greenough House, North Yard Archaeogeophysics, Jamaica Plain, Massachusetts, John M. Steinberg, Christa M. Beranek, John Schoenfelder, Kathryn A. Catlin

Andrew Fiske Memorial Center for Archaeological Research Publications

An archaeogeophysical survey was carried out in May 2010 using Geonics EM-38 RT and a Malå Ground Penetrating Radar (GPR) system with a 500 MHz antenna over an 28x26 m grid immediately northeast of the Loring-Greenough house in Jamaica Plain, MA. Three major anomalies were identified. These anomalies have not been ground truthed, but they appear to be archaeological features. First, we suggest that there is builders trench just north of the house. Second, we suggest that there could be three east-west garden paths or other landscape features about 30 cm below the surface crossing the entire length of the …

Functional And Bioactive Components From Mackerel (Scomber Scombrus) And Blue Whiting (Micromesistius Poutassou) Processing Waste, Zied Khiari Nov 2010

Functional And Bioactive Components From Mackerel (Scomber Scombrus) And Blue Whiting (Micromesistius Poutassou) Processing Waste, Zied Khiari

Doctoral

The use of fish processing waste from an oily fish model (mackerel, Scomber
scombrus) and a white fish model (blue whiting, Micromesistius poutassou) as a source of functional and bioactive compounds was investigated.
Gelatines were extracted from fish heads and skins using pre-treatment with
different organic acids (acetic, citric, lactic, tartaric and malic acids). Gelatines from fish bones were extracted after pre-treating the bones either chemically or enzymatically. The type of pre-treatment affected the yield, colour, turbidity, amino acid profiles as well as functional properties of fish gelatines. Mackerel gelatines formed stronger and more stable gels than blue whiting. Acetic …

Match–Mismatch Regulation For Bluegill And Yellow Perch Larvae And Their Prey In Sandhill Lakes, Jeffrey C. Jolley, David W. Willis, Richard S. Holland

Nebraska Game and Parks Commission: Staff Research Publications

Food availability may regulate fish recruitment, both directly and indirectly. The availability of zooplankton, especially to newly hatched larvae, is thought to be crucial to their early growth and survival. We examined stomach contents of larval bluegill Lepomis macrochirus and yellow perch Perca flavescens in Pelican Lake and Cameron Lake, Nebraska, in 2004 and 2005. We also determined zooplankton availability and calculated prey selection using Chesson’s a. In addition, we investigated potential match–mismatch regulation of recruitment from 2004 to 2008. Bluegill positively selected copepod nauplii and Bosmina spp., and yellow perch often selected copepods. Abundant zooplankton populations were available for …

On Scientific Research: The Role Of Statistical Modeling And Hypothesis Testing, Lisa L. Harlow Nov 2010

On Scientific Research: The Role Of Statistical Modeling And Hypothesis Testing, Lisa L. Harlow

Journal of Modern Applied Statistical Methods

Comments on Rodgers (2010a, 2010b) and Robinson and Levin (2010) are presented. Rodgers (2010a) initially reported on a growing trend towards more mathematical and statistical modeling; and a move away from null hypothesis significance testing (NHST). He defended and clarified those views in his sequel. Robinson and Levin argued against the perspective espoused by Rodgers and called for more research using experimentally manipulated interventions and less emphasis on correlational research and ill-founded prescriptive statements. In this response, the goal of science and major scientific approaches are discussed as well as their strengths and shortcomings. Consideration is given to how their …

Modelling Uncertainty Caused By Internal Waves On The Accuracy Of Mbes, Travis Hamilton, Jonathan Beaudoin Nov 2010

Modelling Uncertainty Caused By Internal Waves On The Accuracy Of Mbes, Travis Hamilton, Jonathan Beaudoin

Center for Coastal and Ocean Mapping

A 3D ray tracing model has been developed to estimate the effects of internal waves upon the accuracy of multibeam echosounders (MBES). A case study examines the variability in these effects as a function of survey line direction and also considers the case of improving 2D ray tracing models with wave parameters derived from MBES water column imagery. Results indicate that, under certain circumstances, the effects of internal waves can prove to be a significant source of uncertainty that detracts from the ability to efficiently map the seafloor with wide swath angles.

Stability And Charge Transfer Levels Of Extrinsic Defects In Linbo₃, Haixuan Xu, Aleksandr V. Chernatynskiy, Donghwa Lee, Susan Sinnott, Venkatraman Gopalan, Volkmar Dierolf, Simon R. Phillpot

Physics Faculty Research & Creative Works

The technologically important incorporation of extrinsic defects (Mg2+, Fe2+, Fe3+, Er3+, and Nd3+) in LiNbO3 is investigated using density-functional theory combined with thermodynamic calculations. Defect energies, the charge compensation mechanisms, and charge transfer levels, are determined for congruent and stoichiometric compositions. In general, under congruent (Nb2O5-rich) conditions impurities occupy lithium sites, compensated by lithium vacancies. Under stoichiometric (Li2O-rich) conditions, impurities occupy both lithium and niobium sites. The effects of the concentration of Mg on the dominant defect and site occupancy are analyzed. In …

Learning Computational Thinking From Rapid Digital Game Creation, Praveen Kuruvada, Daniel Asamoah, Nikunj Dalal, Subhash Kak

Management Information Systems Faculty Publications

Computational Thinking (CT) has been described as a universally applicable ability such as reading and writing. In this paper, we describe an innovative pedagogy using Rapid Digital Game Creation (RDGC) for learning CT skills. RDGC involves the rapid building of digital games with high-level software that requires little or no programming knowledge. We analyze how RDGC supports various CT concepts and how it may be mapped to equivalent Java concepts by building the same game using both RDGC and Java. We discuss the potential benefits of this approach for attracting computing majors, as a precursor to learning formal programming languages, …
