Perception Of Stressors By 9th And 12th Grade Students Utilizing The Youth Adaptation Rating Scale, Michael James Krummel

Dissertations and Theses

Stress is a fact of life. There has been much research done since the early 1970's dealing with the various aspects and relationships of stress and life events for all stages of human development. The purpose of this study was to investigate perceived life-event stressors of 9th grade and 12th grade students in three Pacific Northwest rural schools. The study also sought to a) ascertain whether male students in the 9th grade and 12th grade perceive stressful life events differently than female students in the same grade, and b) explore if there was a difference in perceptions of students of …

And what is their emergent adaptation pattern to the U.S. university classroom?

A Study Of The Narrative Skills In Kindergarten Children With Normal, Impaired, And Late Developing Language Development, Lisa L. Mcfarland

Dissertations and Theses

Children's narrative language plays a critical role in guiding the transition between oral language and literacy (Roth & Spekman, 1989; Westby, 1989). Narrative comprehension and production by normally achieving and language delayed school-aged children have been studied. Many of these studies have involved story retellings. Few have studied how spontaneously produced narratives are organized especially by young children.

Within And Beyond Boundaries In Henri Bosco's Le Mas ThéOtime, Barbara Marguerite Schaff

Dissertations and Theses

Spiritual, mystic and natural boundaries haunt the writings of Henri Bosco. Critics such as Bachelard have studied Bosco's interpretation of the natural elements and noted his sensitive portrayal of the protagonists with a focus on their unconscious desires by the use of this device. In Le Mas Theotime Bosco has unleashed his artistic and poetic creativity in addition to his passion for nature. Indeed, of all of Bosco's novels, perhaps this one exemplifies the quintessential harmony of man with nature. As suggested by Jean-Claude Godin: " ... il n'y a que dans Le Mas Theotime oil elles soient veritablement au …

Multiplexed Pipelining : A Cost Effective Loop Transformation Technique, Satish Pai

Dissertations and Theses

Parallel processing has gained increasing importance over the last few years. A key aim of parallel processing is to improve the execution times of scientific programs by mapping them to many processors. Loops form an important part of most computational programs and must be processed efficiently to get superior performance in terms of execution times. Important examples of such programs include graphics algorithms, matrix operations (which are used in signal processing and image processing applications), particle simulation, and other scientific applications. Pipelining uses overlapped parallelism to efficiently reduce execution time.

"Staying" And "Straying" : Social Reproduction And Resistance To Secularization, Lisa Graham Mcminn

Dissertations and Theses

This thesis explores how church-founded liberal arts colleges--specifically fundamental/evangelical liberal arts colleges--stayed the drift toward secularization. It uses comparative case studies to examine the structures and beliefs which enabled "staying" schools to resist secularization. Social reproduction theories are used to explain both the reproduction of the dominant culture (secularization) and the reproduction of a subculture (fundamentalism/evangelicalism). Secularizing institutions conform to state incentives and so reproduce what the state sees as necessary for societal survival. Resisting institutions isolate themselves from the dominant culture by establishing boundaries which let in only what accords with the church and so reproduce a culture the …

Multiple Code Switching In An Okinawan Speech Community: An Ethnographic Perspective, Izumi Kawamitsu

Dissertations and Theses

The ethnography of communication is a mode of inquiry which investigates relationships between language and culture in a particular speech community. Based on the ethnographic perspective, this study examines a certain way of speaking at a specific historical moment in a specific community. The major focus is two disc jockeys who are characterized as "trilingual" speakers (Japanese-English-Okinawa dialect) and their code switching activities in an Okinawan local radio program.

The three-month field study took place on the island of Okinawa. Data were collected from observations at the two radio stations, transcriptions of the program, and interviews with the DJs, the …

Studies Of Ecological Factors That Affect The Population And Distribution Of The Western Gray Squirrel In Northcentral Oregon, Susan Ann Foster

Dissertations and Theses

The western gray squirrel (Sciurus griseus griseus Ord) occur only in the Pacific states and in a small corner of extreme western Nevada. Field studies of aspects of the ecology of the most widely distributed subspecies of western gray squirrel (S. griseus) were conducted at three sites in the ponderosa pine-Oregon white oak zone on the eastern slopes of Mt. Hood, Wasco County, Oregon, between 1981 and 1989. From 1981 through 1987, a Hunter Cooperation Program provided remains of squirrels shot during the annual late summer-early autumn hunting season. Other data were gathered through capture and release studies, radiotelemetry, and …

Simulation Design, Role Identification And Attitude Change In A High Technology Culture, Terry Robert Schumacher

Dissertations and Theses

Gaming-simulations (G-S) are those in which participants play roles, make decisions and receive feedback while interacting with a simulation model. This study used attitude change to measure of G-S effectiveness in exploring questions relating simulation design and effectiveness. To define participant attitudes and the content for a simulation, the organizational culture of a software engineering firm was studied using an ethnographic approach. Inconsistencies between the existing culture and expressed ideals were measured using an 40 item attitude questionnaire drawn from statements made during interviews. Simulation structure and participant cognitive style were factors hypothesized to influence identification with a simulation role. …

This study examined the phenomenon of multiple and continuous change and the adjustments teachers made in response to the phenomenon. The research questions posed by this study are: 1. Is there a phenomenon of multiple and continuous change and if so how is it characterized by the participants? 2. Is there an effect of multiple and continuous change on the participants, if so, how do the participants adjust to the phenomenon and how can these adjustments be described? Methodologically, the strategy for this study was designed to allow for the generation of theory since multiple and continuous change has not …

People, Programs, And Politics: Two Case Studies Of Adult Literacy Classes, Rita Collins

Dissertations and Theses

Past research has not sufficiently addressed the question of what types of adult literacy instructional practice are recognized by participants, i.e., students and teachers, as facilitating learning in Adult Basic Education (ABE) classes. The purpose of this study was to describe instructional practices in two urban literacy programs serving low level adult readers, and to identify which practices were effective in meeting student needs. Effectiveness was measured by the ability of students to achieve learning objectives identified by themselves and the teacher, and included attendance patterns and student participation. Quantitative measures of achievement were not used as criteria since few …

Theoretical And Experimental Evaluation Of Hysteresis In Atmospheric Chemistry, Theodore Alan Haigh

Dissertations and Theses

This treatise is a recapitulation of the theoretical and experimental study of hysteresis in atmospheric kinetics. The original problem arose from a theoretical study of a series of reactions for clean air. Upon evaluation a bistable equilibrium was predicted. The steady-state analysis had delineated a metastable region for the set of reactions. This bounded region is the hysteresis that this research project evaluated.

State Industrial Policy And The Autonomy Of State Leaders: Evidence From The Oregon Experience, Matthew I. Slavin

Dissertations and Theses

This research identifies variables that determined the amount of autonomy Oregon's gubernatorial leadership possessed in formulating and implementing the Regional Strategies program, centerpiece of industrial policy in Oregon during the latter half of the 1980s. The literature on state industrial policy points to instances in which the leaders of America's state governments are acting autonomously. Gubernatorial actors appear to be formulating industrial policy goals independent of powerful non-state groups and other state actors and developing the capacity to transform their policy preferences into authoritative actions. The literature is largely devoid, however, of any systematic accounting of the variables that determine …

Preparation Of Electron Donor And Acceptor Molecules For Porphyrin Derivatization, Christoph Hoefler

Dissertations and Theses

The Relationship Between The Use Of Graphophonic Strategy And The Success In English Vocabulary Learning For Chinese Students, Ching-Chih Christine Huang

Dissertations and Theses

For Chinese EFL learners, the skill of vocabulary learning is one of the most essential elements in their English learning process. Many Chinese students transfer their familiar character-learning strategies, which include shape identification and rote memorization, in their English word-learning process. As a result, they may spend time and effort associating the shape, the sound, and the meaning of an English word before they learn and memorize it. Since they do not take advantage of the correspondence between the print and the sound, their vocabulary-learning process seems to be less effective.

Seasonal Patterns Of Melatonin, Cortisol, And Progesterone Secretion In Female Lambs Raised Beneath A 500-Kv Transmission Line, Jack Monroe Lee Jr.

Dissertations and Theses

There is ongoing controversy about the possibility of adverse biological effects from environmental exposures to electric and magnetic fields. These fields are produced by all electrical equipment and appliances including electrical transmission lines. The objective of this environmental science study was to investigate the possible effects of a high voltage transmission line on domestic sheep (Ovis aries L,), a species that can often be found near such lines. The study was primarily designed to determine whether a specific effect of electric and magnetic fields found in laboratory animals also occurs in livestock under natural environmental conditions. The effect is the …

Orthogonal And Nonorthogonal Expansions For Multi-Level Logic Synthesis For Nearly Linear Functions And Their Application To Field Programmable Gate Array Mapping, Ingo Schafer

Dissertations and Theses

The growing complexity of integrated circuits and the large variety of architectures of Field Programmable Gate Arrays (FPGAs) require sophisticated logic design tools. In the beginning of the eighties the research in logic design was concentrated on the development of fast two-level AND-OR logic minimizers like the well known ESPRESSO. However, most logic functions have a smaller and often faster circuit realization as a multi-level circuit. Thus, synthesis tools emerged for the minimization of the circuit area in a multi-level realization. Most of these synthesis tools are based on the "unate paradigm". Therefore, the synthesis methods are only advantageous for …

Spontaneous Coherent Pulsations In Standing-Wave Laser Oscillators : Stability Criteria, Pitak Chenkosol

Dissertations and Theses

The stability criteria for single-mode standing-wave laser oscillators in the strongly homogeneously broadened limit are reported for the first time. Two types of stability criteria are presented. The first type, called type 1, corresponds to the minimum value of threshold parameter for which an infinitesimal perturbation away from steady state grows into an oscillatory solution. Another type of stability criteria, called type 2, corresponds to the minimum value of threshold parameter for which large amplitude oscillatory solutions do not decay to the steady state solution. Undamped pulsations in single mode strongly homogeneously broadened standing-wave laser oscillators are found to occur …

Word Retrieval Behaviors Of Aphasic Adults In Conversational Speech : A Preliminary Study, Priscilla Jane Blake

Dissertations and Theses

Word retrieval difficulties are experienced by almost all aphasic adults. Consequently, these problems receive a substantial amount of attention in aphasia treatment. Because of the methodological difficulties, few studies have examined WRBs in conversational speech, focusing instead on confrontational naming tasks in which the client is asked to retrieve a specific word. These studies have left unanswered questions about the WRB processes.

The purposes of this study were to: (1) develop profiles of WRB for moderately impaired aphasic adult clients and examine these profiles for evidence that reflects the level of breakdown in the word retrieval process, and (2) determine …

Multidimensionality Of Power Use In Organizations And Its Correlates, Weizhong Dong

Dissertations and Theses

The present study was conducted to examine power use patterns and general power use strategies in organizations multidimensionally (i.e., downward, upward, and lateral directions of power use), to extend and explain previous findings by Kipnis et al. (1980), with reference to situational effects on multidimensional power use. The samples in this study consist of 230 full-time managers who were from eight local businesses, and a second sample of 140 college students who worked over 15 hours a week at the time of the study. Two exploratory factor analyses resulted in five commonly used power patterns and two general power use …
