Modeling Integrated Water User Decisions In Intermittent Supply Systems, David E. Rosenberg, Tareq Tawarneh, Rania Abdul-Khaleq, Jay Lund Jan 2007

Modeling Integrated Water User Decisions In Intermittent Supply Systems, David E. Rosenberg, Tareq Tawarneh, Rania Abdul-Khaleq, Jay Lund

Civil and Environmental Engineering Faculty Publications

We apply systems analysis to estimate household water use in an intermittent supply system considering numerous interdependent water user behaviors. Some 39 household actions include conservation; improving local storage or water quality; and accessing sources having variable costs, availabilities, reliabilities, and qualities. A stochastic optimization program with recourse decisions identifies the infrastructure investments and short-term coping actions a customer can adopt to cost-effectively respond to a probability distribution of piped water availability. Monte Carlo simulations show effects for a population of customers. Model calibration reproduces the distribution of billed residential water use in Amman, Jordan. Parametric analyses suggest economic and …

Self-Determined Employment Preference For Youth In Transition From School To Work In Rural Areas, Robert L. Morgan, R. B. Morgan Jan 2007

Self-Determined Employment Preference For Youth In Transition From School To Work In Rural Areas, Robert L. Morgan, R. B. Morgan

Special Education and Rehabilitation Counseling Faculty Publications

Self-determination, or the ability to identify and achieve goals based on a foundation of knowing and valuing oneself, is both a legal right and a responsibility of an individual. Self-determined employment is consistent with contemporary practice, outcome-based research, and the reauthorization of the Individuals with Disabilities Education Act of 2004. In this article, we describe three challenges facing youth with disabilities in rural areas related to determining their own employment, including (a) extensive or chronic poverty in some rural areas as a factor limiting selection of preferred employment, (b) intensive competition for limited jobs available, and (c) the potential for …

Integrated Crisis Mapping: Towards A Publics-Based, Emotion-Driven Conceptualization In Crisis Communication, Yan Jin, Augustine Pang, Glen T. Cameron Jan 2007

Integrated Crisis Mapping: Towards A Publics-Based, Emotion-Driven Conceptualization In Crisis Communication, Yan Jin, Augustine Pang, Glen T. Cameron

Research Collection Lee Kong Chian School Of Business

Extending current situation-based conceptualizations of crisis response, this paper develops a more generic and systemic approach tounderstanding the role of emotions in crisis situations. Taking an integrated approach, the authors propose a public-based, emotion-drivenperspective to crisis communication modeling, mapping different crisistypes, and underpinning them with two continua, the organization’s involvement with the crisis issue and primary public’s coping strategy. Thepaper further argues that the appropriate crisis response and tools tomanage a crisis should address the full range of emotions for optimal effectiveness at both strategic and tactical levels.

Mental And Physical Conditions Encountered In Child Protection And Juvenile Justice, 2007 Edition, Gregg Wright, Victoria Weisz, Christine Wiklund

Center on Children, Families, and the Law (and Related Organizations): Publications

Any grouping of mental and physical conditions risks overemphasizing or mischaracterizing distinctions between mind and body, between thought and emotion, between environment and heredity, even between causes and symptoms. For convenience, and to reflect common usage, we have chosen to group chapters in this book under five headings: Physical Problems, Cognitive Problems, Emotional and Behavioral Problems, Assessments, and Therapies.

Newspaper Vs. Non-Newspaper Litigants In The U.S. Supreme Court, 1964-2001, Edward L. Carter, James C. Phillips

Faculty Publications

Newspapers have been involved as litigants in some of the most significant First Amendment cases to come before the U.S. Supreme Court. Particularly since the groundbreaking case New York Times Co. v. Sullivan in 1964, newspapers have played a prominent role in Supreme Court cases that have defined many important points of First Amendment doctrine and have tested the nation's commitment to freedom of expression. Newspapers have successfully challenged, among other regulations, strict liability for defamation, a mandatory right of reply for political candidates, prior restraint of publication and a courtroom closure order in a high-profile state murder trial. But …

Enhancing Diversity In An Appointive System Of Selecting Judges, Leo M. Romero Jan 2007

Enhancing Diversity In An Appointive System Of Selecting Judges, Leo M. Romero

Faculty Scholarship

Any system for selecting judges must be legitimate, and it will not be perceived as legitimate if it excludes certain members of the bar or if it makes it difficult for different groups to get its members on the bench. For an appointive system1 to be perceived as legitimate, it must ensure that diversity is considered in nominating candidates and in appointing judges. This Article will examine the different measures that states, with a particular focus on New Mexico, have adopted in order to enhance diversity in their appointive systems and then propose ways to structure an appointive system that …

Wireless Video Telephony Performance Enhancements: Towards Applied Network Engineering Approach, Justin Madigan, Fei Hu Jan 2007

Wireless Video Telephony Performance Enhancements: Towards Applied Network Engineering Approach, Justin Madigan, Fei Hu

Articles

The aim of this network engineering research is to improve video transmission performance (such as end-to-end delay) in video telephony applications in cellular network scenarios. There exists a definite need for quality-of-service (QoS) and guaranteed throughput when using streaming media. However, in wireless environments where resources are precious, this is often not possible, especially with a large user base that is communicating simultaneously. Not only does traffic load pose a problem, but also the inherent instability of the radio links makes the task considerably more difficult. This presents the need for a new method for undertaking the task of wireless …

Application Of Soft Computing Techniques To Estimate The Effective Young's Modulus Of Thin Film Materials, Ajay Pasupuleti, Ferat Sahin Jan 2007

Application Of Soft Computing Techniques To Estimate The Effective Young's Modulus Of Thin Film Materials, Ajay Pasupuleti, Ferat Sahin

Articles

This research aims at characterizing and predicting the Young’s Modulus of thin film materials that are utilized in Microelectromechanical systems (MEMS). Recent studies indicate that the mechanical properties such as Young’s Modulus of thin films are significantly different from the bulk values. Due to the lack of proper understanding of the physics in the micro-scale domain the state-of-art estimation techniques are unreliable and often unfit for use for predicating the mechanical behavior of slight modifications of existing designs as well as new designs. This disadvantage limits the MEMS designers to physical prototyping which is cost ineffective and time consuming. As …

Teacher Efficacy In The Implementation Of New Curriculum Supported By Professional Development, Douglas Shields Bennett

Graduate Student Theses, Dissertations, & Professional Papers

A large body of literature regarding professional development and its effects on teaching and student achievement and learning has emerged over the last decade. There are many teachers who either have limited access to professional development activities or who have access and choose not to take part in professional development activities. This qualitative study employed a phenomenological tradition in describing the "lived experiences" of participants involved in the implementation of new curriculum. Fourteen teachers and seven principals were purposefully selected to be part of this study in a rural school jurisdiction in southern Alberta. Through a qualitative analysis, this study …

The Effects Of Forest Fires On Runoff Rates: The Role Of Duff Removal And Surface Sealing By Vegetative Ash, Western Montana, Victoria Balfour

Graduate Student Theses, Dissertations, & Professional Papers

Increases in runoff and erosion following a forest fire are often attributed to the removal of the surface duff and litter, the formation water repellent soils, and surface sealing. There has been considerable work on the influence of water repellency on post-fire runoff, however few studies have addressed the hydrologic importance of litter and duff consumption and surface sealing. To further understand these processes, six controlled burns were conducted within Lubrecht Experimental Forest, Western Montana. Three of the study sites were situated on a granitic sandy loam soil formed from quartz monzonite, with Lodgepole pine (Pinus contorta) and Douglas fir …

Practical Approaches To Treating Patients With Bipolar Disorder, Jane E. Neu, Susan M. Denisco Jan 2007

Practical Approaches To Treating Patients With Bipolar Disorder, Jane E. Neu, Susan M. Denisco

Nursing Faculty Publications

Many patients present to a primary care setting with symptoms of a mood disorder. These symptoms may be indicative of an anxiety disorder or a depressive disorder, but they may also represent bipolar disorder, which is more common than many practitioners think. Correctly diagnosing bipolar disorder can be complex, because patients tend to seek treatment when they are experiencing the symptoms of depression or anxiety rather than mania or hypomania. Comorbid disorders such as substance abuse and anxiety disorders may complicate the clinical presentation. Failing to correctly diagnose bipolar disorder can have serious consequences in terms of patients' morbidity and …

Externalizing The Duty: A Cause Of Action Where Crown Failure To Consult First Nations Results In Third Party Loss, Ashley B. Ayliffe Jan 2007

Externalizing The Duty: A Cause Of Action Where Crown Failure To Consult First Nations Results In Third Party Loss, Ashley B. Ayliffe

Dalhousie Journal of Legal Studies

The decision-making process underlying Crown authorization of natural resource industry activity may trigger an obligation on the part of the Crown to consult First Nations. Consultation must accord with constitutional standards. Non-compliance can result in restriction of previously authorized third party undertakings. This can be costly and harmful to the industry. This paper assesses the prospects of a cause of action against the Crown in negligence as a potential avenue of compensation for third parties who suffer loss as a result of inadequate Crown consultation. The analysis incorporates relevant facts from several recent cases regarding ‘Haida motions’ and concludes that, …

The Poverty Of Posner's Pragmatism: Balancing Away Liberty After 9/11, David Cole Jan 2007

The Poverty Of Posner's Pragmatism: Balancing Away Liberty After 9/11, David Cole

Georgetown Law Faculty Publications and Other Works

This review of Richard Posner's Not a Suicide Pact: The Constitution in a Time of National Emergency argues that Posner's particular brand of pragmatic utilitarianism is particularly ill-suited to constitutional interpretation, as it seems to negate the very idea of precommitment that is so essential to constitutionalism. Instead, Posner treats the Constitution as little more than an invitation to pragmatic policy judgment, and then employs that judgment through speculative cost-benefit balancing to find constitutionally unobjectionable most of what the Bush Administration has done thus far in the war on terror, including coercive interrogation, incommunicado detention, warrantless wiretapping, and ethnic profiling. …

Maternal Effects And Sexual Selection In The Heliconia Bug, Leptoscelis Tricolor (Hemiptera: Coreidae), Christine Whitney Miller Jan 2007

Maternal Effects And Sexual Selection In The Heliconia Bug, Leptoscelis Tricolor (Hemiptera: Coreidae), Christine Whitney Miller

Graduate Student Theses, Dissertations, & Professional Papers

The early environment experienced by organisms can have significant phenotypic effects that persist throughout life. Parents, mothers in particular, commonly determine these early environments. Maternal effects, or the influence of maternal phenotypes on offspring phenotypes, are therefore likely ubiquitous in natural populations. However, the frequency and evolutionary consequences of maternal effects are largely unknown. Here I show that maternal phenotypes can have large effects on offspring morphology, fecundity, and behavior. I theoretically explore the potential for these effects to resolve the long-standing "lek paradox" in the field of sexual selection. I also empirically investigate these effects in the heliconia bug, …

The Tongue River Bison Jump (24rb2135): The Technological Organization Of Late Prehistoric Period Hunter-Gatherers In Southeastern Montana, Joseph Shawn Hamilton

Graduate Student Theses, Dissertations, & Professional Papers

Bison hunting has long been recognized as a key element of the lifeways of American Indians of the Northwestern Plains. Bison served as an integral component for food, shelter, tools, and clothing. It is no surprise that the importance bison hunting, as a socioeconomic institution, is revealed in the archaeological record of this region. A study of the material culture, most often lithic tools, found at prehistoric bison kills and processing sites allows archaeologists to draw inferences about the technology associated with the procurement of such vital animals. An investigation of bison jump, trap or pound lithic assemblage can provide …

Partnership, Dependence And Protest: The United States And El Salvador, Seen Through Pockets Of Internationals, Paul Brohaugh

Graduate Student Theses, Dissertations, & Professional Papers

El Salvador is intimately connected to the United States, though most U.S. citizens may not realize it, even if they remember the days of El Salvador’s civil war. As it is for much of the world, the United States is for Salvadorans a promised land of plentiful work and peaceful lives. Unlike the rest of the world, however, every Salvadoran has a fighting chance to get here, and a fourth of the population has done so. Salvadoran news in the United States is mostly limited to updates on youth gangs and violence. Violence was the media draw of the 1980s …

Public Relations In Nonprofit Organizations: A Guide To Establishing Public Relations Programs In Nonprofit Settings, Megan Kate Gale Jan 2007

Public Relations In Nonprofit Organizations: A Guide To Establishing Public Relations Programs In Nonprofit Settings, Megan Kate Gale

Graduate Student Theses, Dissertations, & Professional Papers

Public relations has become an increasingly popular topic in the nonprofit community, and the demand for developing piblic relations as a core competency has increased as well. Since many nonprofit organization have limited time and resources for developing fuull-scale public relations programs, many rely on information obtained during one-day workshops or conference presentations presented by public relations professionals who have little or no experience with the concerns of the nonprofit setting. Using a program planning model, this paper describes how nonprofit organizations can increase the capacity and effectiveness of their public relations efforts by building relationships with key stakeholders.
