The Devil Made Me Do It: Replacing Corporate Directors' Veil Of Secrecy With The Mantle Of Stewardship, Constance E. Bagley, Karen L. Page

San Diego Law Review

This Article argues that the nature of the corporate form coupled with an exclusive focus on shareholder value leads to economically and socially inefficient results. The "profit maximization" view of directors' duties ignores the historical reasons why corporations were given special privileges, such as limited liability, by the state. This narrow view should be replaced with a doctrine of stewardship that imposes a more comprehensive view of the corporation's and directors' responsibility to manage the vast resources held in corporate form. This broader view is consistent not only with the values of a free market economy, but also with modem …

Intelligent Control Strategies For An Autonomous Underwater Vehicle, Paul Jason Craven

School of Engineering, Computing and Mathematics Theses

The dynamic characteristics of autonomous underwater vehicles (AUVs) present a control problem that classical methods cannot often accommodate easily. Fundamentally, AUV dynamics are highly non-linear, and the relative similarity between the linear and angular velocities about each degree of freedom means that control schemes employed within other flight vehicles are not always applicable. In such instances, intelligent control strategies offer a more sophisticated approach to the design of the control algorithm. Neurofuzzy control is one such technique, which fuses the beneficial properties of neural networks and fuzzy logic in a hybrid control architecture. Such an approach is highly suited to …

Human Control Of Robotic Mechanisms: Modelling And Assessment Of Assistive Devices, Cathy-Ann Leonie Radix

School of Engineering, Computing and Mathematics Theses

The prescription and use of Assistive Technology, particularly teleprostheses, may be enhanced by the use of standard assessment techniques. For input devices, in particular, existing assessment studies, most of which are based on Fitts' Law, have produced contradictory results. This thesis has made contributions to these and related fields, particularly in the following four areas. Fitts' Law (and background information theory) is examined. The inability of this paradigm to match experimental results is noted and explained. Following a review of the contributing fields, a new method of assessing input devices is proposed, based on Fitts' Law, classical control and the …

Rapid Clock Recovery Algorithms For Digital Magnetic Recording And Data Communications, Paul Michael Smithson

School of Engineering, Computing and Mathematics Theses

The 1990's may well be considered as the era of information technology, with the prevalence of computers, digital communications and hence the need for data storage. Diverse data storage media have been introduced, such as silicon (flash memory) [3] and the CD (Compact Disk) [4], however improvements in magnetic recording has resulted in magnetic media as the prominent leader in mass storage technology. With improvements to the storage medium, the read/write heads and the channel electronics, the capacity of magnetic rigid disks has approximately doubled every 3 years (period 1960-90) [5]. These improvements to the channel, coupled with fast data-access …

A Divided Attention Task To Measure Functional Auditory Comprehension Deficits In Aphasia, Bruce Dewayne Bane

Dissertations and Theses @ UNI

This experiment assessed auditory comprehension in the presence of a divided attention task. Words and nonwords were embedded within the commands of the first subtest of the Revised Token Test (RTT) to comprise the divided attention RTT (dRTT). A statistically significant poor performance was found on the dRTT compared to the RTT. Further, the subjects' performance was found not to change from the beginning to the end of the dRTT suggesting that learning and fatigue were not meaningful variables in their performance. The position of the distractor (e.g., opposite the verb, color adjective, noun, or randomly placed) had mixed affect …

The Relationship Between Attention Deficit Hyperactivity Disorder And Aggression In Children: A Cross-Sectional Study, Eric Wayne Boelter

Dissertations and Theses @ UNI

This study examined the correlation between aggression and ADHD symptoms across several age groups in children.

The chemistry portfolio design is explained in detail including a rationale for each of the portfolio elements. The teacher developed nine portfolio elements of which the students were required to complete five. The nine elements …

Sex, Violence, And Hand Puppets: History And Structure Of Punch And Judy Performance Tradition, James Robert Davis

Dissertations and Theses @ UNI

Punch and Judy are characters who exist only within the boundaries of the puppet theatre, in performances where characters are portrayed by inanimate figures. Nonetheless, the history of the puppet theatre, and particularly that of Punch and Judy, is closely related to the history of more widely accepted, actor-based theatre, where characters are portrayed by human beings. While the two traditions-share many common elements--such as the importance of characterization, direction, and design--the essential difference between actor-theatre and puppetry is the manner in which the performance is presented. The approach of this study is threefold: first, a linear history of the …

Forgiveness Education As A Factor In Adolescent Adjustment To Parental Divorce, Amy L. Knupp

Dissertations and Theses @ UNI

An educational intervention with forgiveness as the goal, was implemented with five adolescents who had experienced a parental divorce. The adolescents were all from a Midwestern city, ages 12-14, and Caucasian. The goal of the intervention was for the experimental participants to forgive their parents for a hurt associated with a parental divorce. An exploratory design with a static control group was used. Five subjects volunteered for the forgiveness education intervention, comprising the experimental group, and five subjects agreed to fill out pre- and post-test measures, for monetary reimbursement, composing the control group. The educational intervention lasted 10 weeks, and …

Personality Characteristics Associated With People Who Frequently Experience Flow, Mark A. Ackerman

Dissertations and Theses @ UNI

Flow is a state of mind that has been found to occur when people become immersed in a challenging activity that matches or slightly exceeds their skill level. It has been suggested that some people may be more likely to enter this state of mind than others. The purpose of this study was to attempt to identify personality traits common to people who frequently experience flow.

Amount of flow generally experienced in 115 college undergraduates was measured with two modified flow measures, the modified Flow State Scale (FSS) and the modified Flow Descriptions Questionnaire (FDQ). Eight personality characteristics were hypothesized …

Pre-Performance Routines And Rhythm: A Comparative Study, Blake Wade Miller

Dissertations and Theses @ UNI

The present study was designed to investigate the effects of pre-performance routine rhythm on novel motor task success. At the center of the study was the comparison of differing characteristics of two theories of motor control: the dynamical systems theory and the schema theory. It was hypothesized that an even pre-performance routine rhythm would be more advantageous to task success than an uneven preperformance routine rhythm, regardless of the rhythmic characteristic of the task. The results concluded the contrary to be more accurate, and indicated that task success was more likely to occur when the pre-performance routine rhythm was congruent …

A Study Of Service Programs At Selected Midwest Universities, Tammy Lee

Dissertations and Theses @ UNI

When students enter a four-year college or university, they begin the journey of higher education. Through direct and indirect means of structured course work, involvement in campus organizations, and other activities, students gain the knowledge and skills crucial to obtaining a career in their chosen field. Although a college or university has primary responsibilities for the education of students, it also has a social obligation to the community in which it is located. One mechanism that has been devised to mutually benefit the students' need to develop as responsible citizens and the communities' need for college or university expertise is …

Juvenile Justice Professionals And The Goal Of Rehabilitation, Heather Bruch

Dissertations and Theses @ UNI

Numerous studies conducted over the past 20 years have suggested that support for rehabilitation in the criminal justice system has decreased. As a result of these findings, an increase in the examination of support for rehabilitation has occurred. According to much of the research on this issue, an important factor in the support of rehabilitation is the attitudes of criminal justice workers. The increasing prison populations are partially responsible for the heightened interest in this issue. It is believed by many that the attitudes of the workers in the criminal justice system have an effect on the success of the …

Structural Disorder And The Origin Of High-Tc Suppression In La₁.₈₇₅Ba₀.₁₂₅ Cuo4−Δ, Daniel Haskel, Edward A. Stern, Fatih Dogan, Arnie R. Moodenbaugh

Materials Science and Engineering Faculty Research & Creative Works

Polarized x-ray absorption fine structure (XAFS) measurements at all La, Ba and Cu sites were used to study local structural features that accompany the strong Tc suppression at: r,,, 1/8 in La₂BaCuO₄. Two critical parameters regulating the strength of hole-lattice coupling in this material were determined, ie, the direction and magnitude of CuO₆ octahedra local tilts. Our findings include the existence of large disorder in the magnitude of the tilt angle about its average value (0), with an rms~~ 2 (0). We suggest that this large disorder strongly scatters a large fraction of states at …

Leadership In Student Organizations: Do Women And Men Lead Stereotypically?, Jennifer Cullen Danielson

Dissertations and Theses @ UNI

Men and women are believed to vary along stereotypical male and female leadership behaviors (Cann & Siegfried, 1990; Eagly & Johnson, 1990). Stereotypic leadership behaviors for men are defined as task and goal oriented behavior, whereas for women, it is interpersonal or social behavior. The present study explored the leadership behavior of male and female students in student organizations at a mid-western state university. The Leadership Practices Inventory (LPI; Posner & Kouzes, 1988) was used to assess leadership behavior in the student organizations. The leaders of 100 student organizations, 50 males and 50 females, were contacted and asked to fill …

Search For Charginos And Neutralinos In E+E- Collisions At Centre-Of-Mass Energies Near 183 Gev And Constraints On The Mssm Parameter Space, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

Searches for charginos and neutralinos are performed with the data collected by the ALEPH detector at LEP at centre-of-mass energies near 183 GeV. In these searches, it is assumed that R-parity is conserved and that the lightest neutralino is the LSP. No evidence of a signal is observed in the 57 pb−1−1 accumulated, which excludes chargino and associated neutralino production up to the kinematic limit over large regions of the MSSM parameter space. Under the assumptions of common gaugino and common sfermion masses at the unification scale, the interplay between the chargino, neutralino and slepton exclusion limits allows a lower …

Meiosis: The Analysis Of Using A Modified Teaching Approach, Christine Marie Graf

Dissertations and Theses @ UNI

It is well documented that to successfully learn genetics an understanding of meiosis is often thought necessary, and to effectively learn meiosis, knowledge ofDNA structure is also thought to be necessary. Based on student misconception research, recommendations for teaching meiosis suggests several modifications of the teaching approach. This study investigated whether the concept of meiosis could be learned successfully by the use of a modified teaching approach based specifically on research recommendations. Modifications included (a) using student generated diagrams, (b) reducing the amount of vocabulary, ( c) clarifying and differentiating the terms used, ( d) using the cell cycle to …

The Reasons For Living Inventory For Adolescents (Rfl-A) : Validation In Three Adolescent Populations, Joe S. Rich

Dissertations and Theses @ UNI

This study is intended to examine further psychometric characteristics of the Reasons for Living Inventory for Adolescents (RFL-A), a self-report measure developed specifically for use with adolescents. Three separate groups were utilized in this study: a psychiatric suicidal group, a psychiatric inpatient non-suicidal group, and a non-clinical control group from a local laboratory school. Specifically, the factor structure, discriminant validity, internal consistency reliability, and convergent validity of the RFLA total and subscales were examined. Overall, results indicated that the five-factor structure that was identified by Osman et al. (1998) was replicated. Further, results showed that the measure demonstrated adequate internal …

Adolescent Depression : Further Examination Of Gender Differences, Elizabeth Marie O'Neill

Dissertations and Theses @ UNI

This study was designed to examine pertinent research questions that remain unanswered by past investigations of adolescent depression. Specifically this study investigated potential differences between high and low scoring depressed adolescents, and whether gender is an influential variable for consideration. Subjects were 175 adolescent boys and girls from a laboratory school in Midwestern Iowa. Subjects were divided into four groups based on gender and responses two questions on the BDI-A. Specifically, the four groups were: boys who scored at or above IO on the BDI-A (sub-clinical group--boys), boys who scored below 10 on the BDI-A (control group--boys), girls who scored …

Presented is a case study of an eight-year-old boy who is learning English as a second language in a midwestern elementary school. The number of students needing ESL and/or bilingual education is rapidly growing throughout the United States. Many non-urban schools and districts must now begin to meet these needs. Observations of the student in various school settings were done over a period of six weeks for a total of 24 hours. Interviews of key personnel provided additional information important to the study. Three themes of concern in regard to the student's educational situation became the focus of the case …

In Their Own Words : Women's Caregiving Experiences, Loralie L. Wiebold

Dissertations and Theses @ UNI

The purpose of this research was to examine the caregiving situation as told by women involved in parent care. With current demographic trends such as increasing longevity and increasing prevalence of chronic diseases, along with structural changes in medical care, the family (or more appropriately women), are called on to provide care to aging family members. Although current literature documents the situation of caregiving women, rarely are their voices heard and words included in pertinent analyses. This study is a qualitative and interpretive study using in-depth, semi-structured interviews with women and participant observation of caregiver support group meetings to understand, …

Gender, Religion, Causal Attributions, And Correctional Orientations Among Juvenile Justice Personnel, Amy Lynn Lyons

Dissertations and Theses @ UNI

The purpose of this quantitative study is to examine the attitudes and orientations of juvenile justice personnel from four urban counties within the state of Iowa. The nonrandom sample used in the present study is secondary and originally collected for a larger study conducted by Leiber (1993). A closed-ended, self-report survey was administered to each respondent. The total sample for the present research is 263. The hypotheses guiding the present study are based on the assumption that women experience religion differently from men, and in turn, will blame society for youth crime and favor orientations supporting diversion.
