An Investigation Of The Development Of The Phonemes /T/ And /K/ In The Speech Of Preschool Children, Glenn Douglas Weybright

Dissertations and Theses

Research regarding children's instrumental articulation development has provided the speech clinician with schedules of speech sound development. These developmental tables list ages when specific phonemes are mastered by normal children. Such schedules tend to give the impression that certain sounds must be developed before others can occur. Menyuk (1972) has expressed a similar point of view regarding phonemes /t/ and /k/. She has hypothesized:

1. that phoneme /t/ must develop before phoneme /k/; and
2. that sound element initial /t/ is mastered at an earlier age than initial /k/. The present investigation was designed to operationally test the validity of Menyuk's observations. …

The Digital Multifunction Power Measuring System, Ralph Warren Shoemaker

Dissertations and Theses

The Digital Multifunction Power Measuring System is the outgrowth of a project involving the design of a prototype precision Digital Watt Transducer for the Bonneville Power Administration (BPA). A prototype Digital Watt Transducer was built and tested since no other device of the desired accuracy was commercially available. Upon partial completion of the project, another Watt Transducer did become available which was essentially identical to our development. Since we could not economically compete with the manufacturer of these Watt Transducers, our project was stopped. Over a period of several months we thought about other ways to apply the experience gained …

Impact Of College Speech Classes On Listening Skills Of Students, Candice Piazza

Dissertations and Theses

The purpose of this study was to determine the impact of college speech classes upon developing improved listening skills. More specifically it sought to determine the extent to which the students who took Speech 100 or 111 have acquired listening skills.

There has been considerable theorizing concerning listening and auding with only a scattering of experimentation. According to existing data, listening would appear to be a complex human behavior that is only partially understood. There are, however definite listener functions, listening conditions and variables that affect listening. Aspects of attention are also important when considering the occurrence or unoccurrence of …

Vibration Damping Characteristics Of Typical Harpsichord Strings, Jack Lee Simmons

Dissertations and Theses

Present-day builders of harpsichords disagree as to the use of iron or carbon-steel wire in their attempt to duplicate the tonal qualities of the early 16th century instruments. The variations in tone produced by vibrating iron and steel wires may be due, at least in part, to differences in their decay characteristics. A wire was set into vibration by placing a section in a magnetic field and passing a variable-frequency alternating current through it. A condition of resonance was established by appropriately selecting frequencies, lengths, and tensions that would simultaneously satisfy the relationship: fr = n/2L(T/p)1/2. Then measurements of decay …

Curanderismo And Health Delivery Services, Jean Margaret Blaesser

Dissertations and Theses

This study explores and describes curanderismo (folk curing) and the cultural disease concepts of mollera caida, empacho, mal de ojo, and susto as researched in a rural Oregon community. Chicano cultural disease concepts and beliefs are then related to modern health delivery services, and a case is made for the need for cultural awareness, respect, and sensitivity on the part of medical personnel who deliver services. The approach of a curandera (curer) and a doctor are compared.

Age, Intelligence, And Socioeconomic Status Variance In Preposition Acquisition By Children, Georgie Hustead

Dissertations and Theses

Numerous linguistic studies have been done to substantiate the importance of prepositions in the English language. However, no normative studies have been done on the acquisition of expressing prepositions.

The purpose of this investigation was to determine if there were demonstrable trends which would indicate a need for normative data on the acquisition of twenty-six prepositions tested on the Expressive Preposition Test (EPT). The study set out to determine at what age levels a given percentage of the prepositions were expressively acquired and if the socioeconomic status (SES) of the child’s family would be a determiner as to the age …

An Exploratory Study Of Depression In Adolescents Placed In Residential Treatment Centers, Shirley D. Hale, Kermit C. Jeffrey, Gerald J. Moneke

Dissertations and Theses

Concerned that depression might be a common malady among youth who are placed in treatment centers for delinquents, we undertook an exploratory study to determine the validity of this premise. The authors of this study have all worked with youth who, for various reasons, have been placed in residential treatment centers. The authors have observed that symptoms of depression seem to be more prevalent in these youth than in non-institutionalized adolescents, and that these symptoms are often perceived as individual pathology rather than emotional responses common to institutionalized youth. We thus began questioning if these were common emotional responses, and …

Interaction Patterns In The Campground, Dennis Lee Rockwood

Dissertations and Theses

The purpose of this project was to examine interaction patterns in various campground settings and to elaborate on camping literature which has suggested that the campground is a social event with high rates of interaction. In exploring this phenomenon, this report utilized observational techniques to document the temporal, spatial, familiarity, numerical, and behavioral dimensions of the observed interactions.

The data suggested that young adults and middle-aged persons were observed to be involved in, and initiated the highest proportions of, interactions. In general, males displayed far greater proportions of initiations than females. The highly developed campground exhibited higher proportions and rates …

Knowledge And Use Of Social Services In Gervais, Oregon, Elizabeth Lewis, Abby Maier, Lajuana J. Morton

Dissertations and Theses

During first year field placement, we worked with a number of rural families, most of them Mexican-American. It seemed to us that rural families in general and Mexican-Americans in particular were not being very well served by social service agencies. We questioned whether this might be due to a lack of Mexican-American perspective in traditional services or perhaps a lack of Mexican-American manpower or at least Spanish-speaking manpower.

This study, then, developed out of a general area of interest that can be stated as three questions: (1) Do rural people (especially Mexican-Americans) feel there is a need for various social …

Intelligibility Of Speech Compared Through Two Limiter Compression Circuits, Lee M. Odell

Dissertations and Theses

Hearing aid manufacturers commonly engineer automatic gain control (AGC) circuits which are aimed at reducing sound tolerance problems and improving speech intelligibility among wearers. The most common type of AGC engineered is one utilizing a fast attack time. The present study was designed to evaluate the effects of both fast and slow attack times on the intelligibility of speech. Twenty-four normal hearing subjects listened to sixty pre-recorded sentences through two types of hearing aid circuits. Thirty sentences were modified by a fast attack AGC circuit, and thirty sentences were modified by a slow attack AGC. The subjects marked one of …

Social Action As Social Change Through A Process Of Insulation, Leonard Siegfred Nelson

Dissertations and Theses

This study has attempted to investigate the radical change in the Greater Portland Council of Churches’ (GPCC’s) organizational goals and actions--from its relative uninvolvement over to its preoccupation with local social, political and economic issues. In the past, classical sociological theory of religion has placed great emphasis on religion’s integrative, or conservative functions in society. Empirical studies have documented the conservative socio-political views of the majority of Protestant parishioners. Knowing this, I expected to find a significant conservative reaction swelling up from the lay parishioners of the GPCC's member congregations. A preliminary investigation revealed this assumption to be invalid. The …

A Study Of The Relationship Between Attitudes Toward Woman's Roles And Career Choices Of Women Graduate Students, Barbara Backstrand

Dissertations and Theses

The purposes of the present study were to explore how American college women view their roles and whether or not women who choose not-traditional-for-women (NTW) careers have more or less social support from significant others for that choice than women who choose traditional-for-women (TW) careers. A related question asked whether aspects of a woman's personal history predict her role attitudes and behavior as an adult.

Physiological And Behavior Studies Of Thelepus Crispus And Its Commensal Halosydna Brevisetosa, John B. Morgan

Dissertations and Theses

Chemical, physical and physiological interactions between the marine commensal scaleworm Halosydna brevisetosa Kinberg and its terebellid host, Thelepus crispus Johnson were investigated. In an experiment designed to test for chemical attraction between the host and commensal, Halosydna were unable to identify the arm in a U-tube choice apparatus leading to the host. In 50 trials, 54% of the commensals crawled into the flow of water from their hosts. Other observations showed that Halosydna made contact with the host by random encounter. After contact, commensals followed tentacles down into the host’s tube and took up a characteristic position along the dorsum …
