Bergmann's Rule In Ectotherms: A Test Using Freshwater Fishes, Mark C. Belk, Derek D. Houston

Faculty Publications

Understanding patterns of variation in body size within and among species is a central question in evolutionary ecology (Schlichting and Pigliucci 1998). The most well known pattern of variation in body size is Bergmann's rule (Bergmann 1847; Mayr 1956). The intraspecific version of Bergmann's rule holds that within endothermic species, body size increases with increasing latitude (or decreasing temperature; Blackburn et al. 1999; Ashton et al. 2000). In general, mammals conform to this rule (Ashton et al. 2000).

Coordinated Target Assignment And Intercept For Unmanned Air Vehicles, Erik P. Anderson, Randal W. Beard, Michael A. Goodrich, Timothy W. Mclain

Faculty Publications

This paper presents an end-to-end solution to the cooperative control problem represented by the scenario where unmanned air vehicles (UAVs) are assigned to transition through known target locations in the presence of dynamic threats. The problem is decomposed into the subproblems of: 1) cooperative target assignment; 2) coordinated UAV intercept; 3) path planning; 4) feasible trajectory generation; and 5) asymptotic trajectory following. The design technique is based on a hierarchical approach to coordinated control. Simulation results are presented to demonstrate the effectiveness of the approach.

Provenance Of Sand In Periglacial Sand Wedges And Sheet Sand, Northeastern Nebraska, Usa, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

Sand-wedge polygons on upland surfaces beneath thin loess in northeastern Nebraska record existence of permafrost around the margin of the Wisconsinan glacier at its maximum advance. Strong unidirectional wind not only kept the upland surfaces free of snow, allowing frost to penetrate deeply and thermal contraction cracks to develop, but also dessicated the surface material so that frost action and sublimation of pore ice could loosen surface material. The strong NW-SE winds deflated soils from upland surfaces, made ventifacts of the cobbles in the lag that remained and created fields of yardangs oriented NW-SE. Sand derived from the soils and …

A Measurement Of Job Satisfaction Indicators Of North Dakota Long Term Health Care Givers, Deborah Moreno

Theses and Dissertations

Long term care facilities in North Dakota and across the nation are experiencing a shortage of Registered Nurses (RNs), Licensed Practical Nurses (LPNs), and Certified Nurse Assistants (CNAs). This shortage is significant as it directly affects the quality of care provided to long term care residents. As long term care is labor intensive, recruitment and retention efforts are critical to these facilities. In a highly competitive labor market, although recruitment is important, retention of current employees is crucial. An integration retention strategy is necessary for the retention of employees. Numerous studies have suggested that job satisfaction is directly related to …

The Awara Verbal System, Susan R. Quigley

Theses and Dissertations

Awara is a language in the Wantoat family spoken by the Awara people of Papua New Guinea. Though it has been mentioned in papers written about the Finisterre-Huon languages and about the Wantoat language (another language in the Wantoat family), it has not been described in depth.

This paper presents a description of the verbal system of the Awara language. The major grammatical constructions described are 1) the verbal morphology, 2) serial-verb constructions, 3) clause chaining, and 4) subordination.

Interesting aspects of the language shown here are 1) the variety of clause types based on the type of subject-indexing suffix, …

Identification Of Immunoreactive Material In Mammoth Fossils, Mary Higby Schweitzer, Christopher L. Hill, John M. Asara, William S. Lane, Seth H. Pincus

Anthropology Faculty Publications and Presentations

The fossil record represents a history of life on this planet. Attempts to obtain molecular information from this record by analysis of nucleic acids found within fossils of extreme age have been unsuccessful or called into question. However, previous studies have demonstrated the long-term persistence of peptides within fossils and have used antibodies to extant proteins to demonstrate antigenic material. In this study we address two questions: Do immunogenic/antigenic materials persist in fossils? and; Can fossil material be used to raise antibodies that will cross-react with extant proteins? We have used material extracted from a well-preserved 100,000-300,000-year-old mammoth skull to …

Introduction: Communities In Crisis, Susanna Trnka

Pacific Studies

This introduction sets the stage for a volume of essays exploring the social, political, and cultural upheavals experienced in Fiji during and after the May 2000 coup led by George Speight. While media and political discourse have largely focused on national-level implications and ethnic divisions, this collection shifts attention to grassroots perspectives, highlighting how ordinary citizens experienced and interpreted the crisis. Drawing on ethnographic fieldwork conducted during or shortly after the coup, contributors examine local discourses, community reactions, and the reconfiguration of identities and power dynamics. The introduction contextualizes the coup within Fiji's broader history of political instability, including the …

Taukei-Vulagi Philosophy And The Coup Of 19 May 2000, Tui Rakuita

Pacific Studies

This essay analyzes how the 19 May 2000 civilian coup in Fiji drew upon an indigenous philosophy of taukei-vulagi (native-foreigner) relations to mobilize support for the antigovernment rebels. Fears of political disempowerment—grounded in the political realities of the Chaudhry government as well as in political propaganda—led many "ordinary" Fijians to support the motives, if not the methods, of the coup. The coup itself, I conclude, can best be understood as a manifestation of the friction between two categories of Fijians—old guards associated with the colonial era and the educated marginalized elite—with Indo-Fijians (contrary to their wishes) dragged in to establish …

This brief uses data from the National Survey of State Systems and Employment for People with Disabilities to explore the varieties of collaboration Medicaid agencies are using and the agencies they are collaborating with.

What Is And Is Not Pathological In Criminal Law, Kyron Huigens

Michigan Law Review

In a recent article in this law review, William J. Stuntz argues that criminal law in the United States suffers from a political pathology. The incentives of legislators are such that the notorious overcriminalization of American society is deep as well as broad. That is, not only are remote corners of life subject to criminal penalties - such things as tearing tags off mattresses and overworking animals - but now crimes are defined with the express design of easing the way to conviction. Is proof of a tangible harm an obstacle to using wire and mail fraud statutes to prosecute …

The Impact Of Density: The Importance Of Nonlinearity And Selection On Flight And Fight Responses, Wendy C. Regoeczi

Sociology & Criminology Faculty Publications

Unlike commonsense notions and the findings from animal research, the literature concerning the effects of density on human social behavior is paralyzed by contradictory findings. This article examines empirically two fundamental issues which could account for this and which are central to the density-crowding debate: (1) whether observed crowding effects are the result of causation or selection and (2)whether individuals are negatively affected by both low and high levels of density. Data from the Toronto Mental Health and Stress study are analyzed using structural equation modeling to investigate these questions. The results support the notion that the effects of density …

Crystalclear: Active Visualization Of Association Rules, Hian-Huat Ong, Kok-Leong Ong, Wee-Keong Ng, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Effective visualization is an important aspect of active data mining. In the context of association rules, this need has been driven by the large amount of rules produced from a run of the algorithm. To be able to address real user needs, the rules need to be summarized and organized so that it can be interpreted and applied in a timely manner. In this paper, we propose two visualization techniques that is an improvement over those used by existing data mining packages. In particular, we address the visualization of "differences" in the set of rules due to incremental changes in …

Vdl: A Language For Active Mining Variants Of Association Rules, Kok-Leong Ong, Wee-Keong Ng, Ee Peng Lim

Research Collection School Of Computing and Information Systems

The popularity of association rules has resulted in several variations being proposed. In each case, additional attributes in the data are considered so as to produce more informative rules. In the context of active mining, different types of rules may be required over a period of time due to knowledge needs or the availability of new attributes. The present approach is the ad-hoc development of algorithms for each variant of rules. This is time consuming and costly, and is a stumping block to the vision of active mining. We argue that knowledge needs and the changing characteristics of the data …

Helping Graduate Level Administrative Courses Support The Importance Of The School Asset, John C. Maciha

Journal of Catholic Education

Facilities management, preventative maintenance, and capital improvements are the concern of many principals, presidents, and boards. University preparation programs for school administrators often lack serious concentration on these areas, mostly due to the increased standards for licensure, certification, and academic degrees. This article attempts to fill that void by inviting school leaders to consider preventative maintenance as an integral part of facilities management.

The Estimation Of Polytomous Item Response Models With Many Dimensions, Nikolai Volodin, Ray J. Adams

Assessment and Reporting

Identification conditions and an improved estimation method for a D-dimensional mixed coefficients multinomial logit model are discussed. This model is a generalisation of the Adams and Wilson (1997) random coefficients multinomial logit and it can be used to fit multdimensional forms of a wide range of Rasch measurement models. The computational demands of the numerical integration required in fitting such models have limited previous implementations to three and perhaps four-dimensional problems (Glas, 1992; Adams, Wilson and Wang, 1997). This paper illustrates a Monte Carlo integration method that permits the estimation of models with much higher dimensionality. The example in …

Determining The Mobility Of Metals Through Coal Combustion Byproducts In Surface Impoundments By Analyzing Leachate From Modified Saturated Hydraulic Conductivity Tests, Michael Joseph Trofinoff

Theses and Dissertations

Surface impoundments are used extensively throughout the utility industry to store the combustion byproducts, or ash, from coal-fired generating facilities. Following combustion, the metals, naturally contained within coal at low concentrations, may become highly concentrated within the ash. These combustion byproducts are then piped out in a water-ash slurry to the surface impoundments where the ash weathers to- a clay- like substance after approximately 10 years. It is feared that these metals that are contained within the ash could possibly leach into the ground and contaminate the local groundwater. Utilizing a open column percolation test to determine the hydraulic conductivity …

Getting Back: Successful Rehabilitation After A Hip Fracture, Carole Florek Hair Phd, Ms, Rn

Dissertations

Fracturing a hip is a devastating experience for the older adult, and mortality and morbidity following a hip fracture are high among this vulnerable population. Mortality rates from 12 to 37 percent have been reported within one year after a hip fracture. It is estimated that 50 percent of individuals who experience hip fractures become partially dependent in activities of daily living, and 33 percent become totally dependent in activities of daily living. Reducing morbidity by improving rehabilitation outcomes is an important healthcare goal for older adults. Motivating participation in rehabilitation activities poses a challenge for professional caregivers. The purpose …

A Neural Network Method For Protein Classification, Arie D. Jones

All-Inclusive List of Electronic Theses and Dissertations

The investigation detailed in this paper attempts to utilize a Leaming Vector Quantization network in order to classify a set of mitochondrial proteins based upon their amino acid sequence. The Learning Vector Quantization network uses a nearest neighbor approach to classification. Input vectors are fed into the network, which produces output vectors. Those output vectors are then matched by means of a distance bias to a corresponding classification vector. The learning and test sets consisted of thirteen similar mitochodrial proteins from seventy-two different species. This provided a pool of over nine hundred proteins to use. Half of the species were …

Response Surface Methodology Of Die-Sink-Electro-Discharge Machined Surfaces, Bhairav Mehta

Theses

The performance of most manufacturing processes depends on numerous parameters and their interactions. Most of the time, selection of an appropriate set of machining parameters is done based on experience, trial and error or both. Electro-discharge machining (EDM) process is complicated and random in nature. The large number of parameters and the inherent complexity of removal mechanism taking place in EDM make it even more difficult to select machining conditions for optimal performance. The objective of this study is to provide information on the relationships between the key input variables and resultant surface roughness and to develop a response model …

Why Negligence Dominates Tort, James A. Henderson Jr.

Cornell Law Faculty Publications

The last several decades of tort scholarship in this country reflect enthusiasm favoring strict enterprise liability as the end position toward which American tort law, appropriately enough, is moving. This Article argues that no such trend is underway; negligence does now, and will in the future, dominate tort. Professor Gary Schwartz reached these same conclusions in a body of work spanning twenty-plus years, culminating in the Restatement (Third) of Torts: Liability for Physical Harm (Basic Principles) project on which he served as Reporter until his untimely death in 2001. This Article describes his work and supports his conclusions with two …
