Hybrid Control Of Seismic Structures With Optimal Placement Of Control Devices, Franklin Y. Cheng, Hongping Jiang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

A theoretical study is carried out for optimal controller placement and effectiveness of a hybrid seismic response control system comprising a viscous fluid damper and a servovalve-controlled hydraulic actuator. A stochastic seismic response of controlled structures is first investigated with nonorthogonal damping and stiffness; then a statistical method for optimal placement of control devices on seismic-resistant structures is developed. With such placement, a hybrid system can achieve greater performance in that much less control force is required to reduce structural seismic response to a given level. This study also shows the hybrid system is superior to both active and passive …

Recent Research And Developments In Cold-Formed Steel Framing, Roger A. Laboube, Wei Wen Yu

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Recent research studies at the University of Missouri-Rolla (UMR) have focused on developing a better understanding of the behavior of cold-formed steel members and truss assemblies. This research was initiated by the more widespread use of cold-formed steel in the residential construction market, and the need to provide structurally reliable, as well as highly economical design solutions. Steel trusses are commonly assembled using C-shaped sections and self-drilling screws. Based on UMR findings, appropriate design recommendations have been proposed for the web and chord members of a truss. Also of concern is the introduction of large holes in the webs of …

Evaluation Of Toxicity, Bioavailability And Speciation Of Lead, Zinc And Cadmium In Mine/Mill Wastewaters, Mujde Erten-Unal, Bobby G. Wixson, Nord L. Gale, Jerry L. Pitt

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The toxicity of common compounds of lead, cadmium and zinc was evaluated in waters similar to that found in the world's largest lead producing area in Missouri.

Estimating The Potential Available Labor Supply For Mid-Sized Iowa Communities, Randal Robert Pilkington

Dissertations and Theses @ UNI

This thesis presents a case study approach to estimate the potential supply of available workers within a laborshed or sub-labor market area. Current labor data are not adequate to estimate the supply of labor and its characteristics in mid-sized Iowa communities. In addition, low unemployment rates are not reflective of the willingness of workers to change jobs. Estimates of underemployment are also missing from any current labor data.

The methodology for this study consisted of conducting a random survey of the potential available labor force for a mid-sized Iowa community's laborshed, defined as the nodal region from which a community …

The Morality Issue: How Darlan Influenced The Allied Unconditional Surrender Pledge In World War Ii, Brian Fiderlein

Dissertations and Theses @ UNI

When World war II began in September 1939, polls indicated that most Americans believed it did not pose a threat to the United States and opposed any involvement by a ratio of 27-to-1.

President Franklin Roosevelt perceived that the power of Nazi Germany and its ideals posed a threat to American democracy. He presented the war to the American public as a moral struggle as well as one for security. The President publicized this view most notably in his Four Freedoms speech and in the Atlantic Charter. Both statements defined the moral goals of basic human freedoms and national self-determination. …

Evaluation Of Revegetation Techniques Used On Degraded Agricultural Land In The Central Avon Catchment, Western Australia, Scott J. Bartholomew

Theses: Doctorates and Masters

The agricultural region in the central Avon catchment is declining in both arable land and native vegetation. This decline has been due to the clearance of large tracts of native vegetation and its subsequent replacement by exotic crops and pasture species. The loss of vegetation has led to regional land degradation in the form of soil erosion and land salinisation. Therefore, changes in land management practices are required to make agricultural production more compatible with land conservation. Revegetation using native plants is the only management solution that integrates both land and ecological conservation with agricultural productivity. The continuation of current …

Fostering Flowers: Women, Landscape And The Psychodynamics Of Gender In 19th Century Australia, Pamela Hodge

Theses: Doctorates and Masters

It is said that when the Sphinx was carved into the bedrock of Egypt it had the head as well as the body of Sekhmet lioness Goddess who presided over the rise and fall of the Nile, and that only much later was the head recarved to resemble a male pharaoh. Simon Schama considered the 'making over' of Mount Rushmore to resemble America's Founding Fathers constituted 'the ultimate colonisation of nature by culture … a distinctly masculine obsession (expressing) physicality, materiality and empirical externality,… a rhetoric of humanity's uncontested possession of nature. It would be comforting to think that, although …

(b) overall task cohesion including attraction to group-task (ATG-T) and group integration-task (GI-T) components, and (c) social cohesion including attraction to group-social (ATG-S ), and group integration-social (GI-S) components. The second study examined the multidimensional nature of cohesion in relation to player satisfaction. Finally, study investigated the relationship between pcrfom1ancc outcome …

Bright Lights, Small City: New Beginnings Of The Singapore Film Industry, Samantha W.M. Tan

Theses : Honours

The Singapore government decided in J9H5 that making movies and turning the country into a regional film centre was an ideal venture to help develop and sustain the country's economic growth. The nation has about 3.7 million people, and although English is studied as the first language, about half of the population (especially the older generation) are more well-versed in their mother tongue, ie. Chinese, Malay or Tamil. Because of this disparity, it would appear that the Singapore market doesn't have the critical mass to sustain a film industry unless the movies are made for export. Little has been written …

Behavioural Contexts For The Expression Of Modern Racism: The Simulated Juror Paradigm, Murray Riggs

Theses : Honours

The central tenet of modem racism theory is that, although overt prejudice seems to have declined, subtle forms of prejudice are still pervasive. The theory predicts that members of a majority racial group will discriminate against members of a minority racial group only when they feel that they can do so without appearing to be prejudiced. Thus, the occurrence of discrimination depends upon the nature of the behavioural context. The purpose of the present study was to explore the implications of modern racism theory in the behavioural domain by employing the simulated juror paradigm. The participants, 338 randomly selected residents …

Psychological Well-Being In The Victims Of Bullying Among Primary School Children, Catherine A. Rice

Theses : Honours

A replication and extension of Rigby and Slee's (1993) study and an investigation of Seligman, Reivich, Jaycox and Gillham's (1995) theory of self-esteem was conducted in one private primary school in Western Australia. The aim of the study was to examine the relationship between the age and gender of victims of bullying with self-esteem of the students and their attitudes towards attending school (Rigby & Slee, 1993), and their explanatory style (Seligman et al., I 995).

Toleration, Autonomy, And Governmental Promotion Of Good Lives: Beyond "Empty" Toleration To Toleration As Respect, Linda C. Mcclain

Faculty Scholarship

This Article considers discontent with liberal toleration as being both too empty, because it fails to secure respect and appreciation among citizens who tolerate each other, and too robust, because it precludes government from engaging in a formative project of helping citizens to live good, self-governing lives. To meet these criticisms, the Article advances a model of toleration as respect, as distinguished from a model of empty toleration, drawing on three rationales for toleration: the anti-compulsion rationale, the jurisdictional rationale, and the diversity rationale. It defends toleration as respect against some common criticisms-emanating from feminist, civic republican, and liberal perfectionist …

International Law And International Relations Theory: A New Generation Of Interdisciplinary Scholarship, Anne-Marie Slaughter, Andrew S. Tulumello, Stepan Wood

All Faculty Publications

Nine years ago, Kenneth Abbott published an article exhorting international lawyers to read and master regime theory, arguing that it had multiple uses for the study of international law. 1 He went as far as to call for a "joint discipline" that would bridge the gap between international relations theory (IR) and international law (IL). Several years later, one of us followed suit with an article mapping the history of the two fields and setting forth an agenda forjoint research. 2 Since then, political scientists and international lawyers have been reading and drawing on one another's work with increasing frequency …

Policing For Profit: The Drug War’S Hidden Economic Agenda, Eric D. Blumenson, Eva Nilsen

Faculty Scholarship

In the following pages, we first describe in more detail how the Drug War’s financial largess has kept its soldiers in business. We then discuss the destructive impact of this economic regime, marshaling evidence to show that the corruption of law enforcement priorities and wholesale miscarriages of justice can be attributed to the operation of these incentives. Finally, we explore potential legal and legislative remedies through which law enforcement may regain its bearings.

Our investigation focuses on the economic underpinnings of current drug law enforcement policy. Drug policy also raises an extraordinarily broad range of moral, health, and criminological concerns, …

The Relationship Between Attributional Style, Self-Concept, And Class Placement In Students With And Without Learning Disabilities, Lynette Ship
