From Individuality To Individualism: A Critique Of The Helping, Timothy B. Smith, Matthew R. Draper

Faculty Publications

Individualistic values characterize contemporary society and many popular approaches to mental health treatment. This paper critiques the individualistic values embedded in the helping professions that implicitly contradict the teachings of Jesus Christ, the surest foundation for mental health interventions. Members of AMCAP are encouraged to search out and replace other problematic values that contradict gospel teachings but that have been integrated into contemporary mental health practice.

Category Of Nonlinear Evolution Equations, Algebraic Structure, And R-Matrix, Zhijun Qiao, Cewen Cao, Walter Strampp

School of Mathematical & Statistical Sciences Faculty Publications

In this paper we deal with the category of nonlinear evolution equations ~NLEEs! associated with the spectral problem and provide an approach for constructing their algebraic structure and r-matrix. First we introduce the category of NLEEs, which is composed of various positive order and negative order hierarchies of NLEEs both integrable and nonintegrable. The whole category of NLEEs possesses a generalized Lax representation. Next, we present two different Lie algebraic structures of the Lax operator: one of them is universal in the category, i.e., independent of the hierarchy, while the other one is nonuniversal in the hierarchy, i.e., dependent on …

Can Reading Help?, Chris Crowe

Faculty Publications

I've not slept well for many months. Until recently l had assumed that my fitful nights were merely the combined effects of impending writing deadlines, ALAN presidential duties, middle age, a long list of incomplete house and yard chores, a six-digit mortgage, my university students and classes, a neurotic and noisy cat, and two teenage daughters.

Some nights are worse than others, and I've supposed that when stress goes up, sleep goes down. But I've also noticed lately that when things go bump in the night, I jerk awake wondering if it was just wind, the dog, a neighbor's car …

Trust And The Decision To Outsource: Affective Responses And Cognitive Processes, Mark Hansen, J.L. Morrow Jr.

Faculty Publications

Many of the various forms of cooperative strategy that firms are pursuing in today’s economy entail the placing of important business functions in the hands of a partner. This paper examines the role of trust in the decision by a producer to place the marketing function in the hands of another entity, namely a cooperative. Although others have studied the effect of what may be termed general trust on inter-organizational relationships, few have examined the antecedents of that trust. We propose a model in which affective responses and cognitive processes are precursors to a sense of general trust, which, in …

An Imaging System Correlating Lip Shapes With Tongue Contact Patterns For Speech Pathology Research, Christopher Dromey, Daniel Bates, Xiaoqian Xu, Sameer Antani, D J. Lee

Faculty Publications

In this research, an imaging system was built to work with a newly developed electronic device to help people produce sounds correctly. The system consists of two parts, the internal tongue contact pattern data collection and the external lip shape information analysis. The tongue position information was gathered using the palatometer, an innovative tongue contact pattern-tracking device invented by Dr. Samuel Fletcher. The lip shape information was collected by processing images taken from people articulating different sounds. We developed an efficient color image segmentation technique to extract lip contour points and form a closed curve for shape analysis. The geometry …

Embryo And Gamete Development Upon Exposure To Cca Components: Cro3, Cuo, And As2o5, Nerbana Talaat-Elsebaei Mahmoud

Theses and Dissertations in Biomedical Sciences

Production of functional gametes and healthy embryos is essential for proliferation of all vertebrates, especially humans. Many compounds have toxic effects on developing gametes and embryos among which are chromium trioxide (CrO₃), cupric oxide (CuO) and arsenic pentaoxide (As₂O₅) as a mixture (CCA) or individually. Controversy surrounding the safety of CCA-treated wood centers primarily on the toxicity of its components and the potential for these metals to be released from the wood.

The aim of this research is to test the hypothesis that CCA components have deleterious effects on embryo development, oocyte maturation and …

Boussinesq Model And The Relative Trough Froude Number (Rtfn) For Wave Breaking, Takashi Okamoto

Civil & Environmental Engineering Theses & Dissertations

The relative trough Froude number (RTFN) theory is a new phase-resolving type, wave breaking trigger model introduced by Utku (1999) and Utku and Basco (2002). Based on the moving hydraulic jump concept, this model provides a better implementation of wave breaking in terms of hydrodynamics. Development of computer resources permits the use of the phase-resolving type, Boussinesq wave models in nearshore areas. The Boussinesq equation, however, does not include the physics of wave breaking, so that an additional mechanism is required to initiate wave breaking in the model. The main objective of this study is to develop a new wave …

Proactive Personality And The Big Five As Predictors Of Motivation To Learn, Jonathan E. Turner

Psychology Theses & Dissertations

In an environment of changing psychological contracts, corporate downsizing, and increases in alternative self-paced training delivery channels, motivation to learn is believed to represent a key variable in employee self-development that distinguishes employees who will thrive from those who will not. Predicting this variable, then, becomes an important step in managing workforce development and helping employees help themselves. Therefore, the efficacy of relevant personality characteristics as predictors of motivation to learn was investigated. Proactive personality and the Big Five factors of personality were hypothesized to be predictive of motivation to learn. These personality variables are relevant because they have been …

Development Of An Aggregation Methodology For Risk Analysis In Aerospace Conceptual Vehicle Design, Trina Marsh Chytka

Engineering Management & Systems Engineering Theses & Dissertations

The growing complexity of technical systems has emphasized a need to gather as much information as possible regarding specific systems of interest in order to make robust, sound decisions about their design and deployment. Acquiring as much data as possible requires the use of empirical statistics, historical information and expert opinion. In much of the aerospace conceptual design environment, the lack of historical information and infeasibility of gathering empirical data relegates the data collection to expert opinion.

The conceptual design of a space vehicle requires input from several disciplines (weights and sizing, operations, trajectory, etc.). In this multidisciplinary environment, the …

The Contribution Of Enactments To Structural Family Therapy: A Process Study, Stephanie Fellenberg

Psychology Theses & Dissertations

In an era where the effectiveness of many forms of psychotherapy has been thoroughly examined, the focus of many researchers has shifted from investigating outcome to exploring therapeutic processes. Process studies serve to identify the active ingredients of therapy—that is, those interventions that bring about in-session changes. This process study examines the relationship between the use of enactments, a structural family therapy intervention, and in-session change as observed over the course of the session. Change was measured by the amount of change that occurred in the core problem dynamic, that is, the most prominent pattern of dysfunctional family …

Shock Wave Dispersion In Weakly Ionized Gas, Prasong Kessaratikoon

Physics Theses & Dissertations

Electrodeless microwave (MW) discharge in two straight, circular cylindrical resonant cavities in TE_1,1,1 and TM_0,1,2 modes were introduced to perform additional experimental studies on shock wave modification in non-equilibrium weakly ionized gases and to clarify the physical mechanisms of the shock wave modification process. The discharge was generated in 99.99% Ar at a gas pressure between 20 and 100 Torr and at a discharge power density less than 10.0 Watts/cm³. Power density used for operating the discharge was rather low in the present work, which was determined by evaluating the power loss inside the resonant cavity. …

Automated Rating Of Esl Essays, Deryle W. Lonsdale, Diane Strong-Krause

Faculty Publications

To date, traditional NLP parsers have not been widely successful in TESOLoriented applications, particularly in scoring written compositions. Re-engineering such applications to provide the necessary robustness for handling ungrammatical English has proven a formidable obstacle. We discuss the use of a nontraditional parser for rating compositions that attenuates some of these difficulties. Its dependency-based shallow parsing approach provides significant robustness in the face of language learners’ ungrammatical compositions. This paper discusses how a corpus of L2 essays for English was rated using the parser, and how the automatic evaulations compared to those obtained by manual methods. The types of modifications …
