Role-Taking And Behavior, Jane Wynne Uphoff

Dissertations and Theses

The present study examined the relationship between the cognitive skill of role-or perspective-taking and naturally occurring behavior of behaviorally disordered children. Twenty-six boys, aged five years, nine months to twelve years, two months were tested and observed at their treatment facility. It was predicted that children who could take the perspective of others would prefer peer to adult interaction, would more likely give positive attention to their peers and would be more likely to use effective language than their non perspective-taking peers. These and related hypotheses were examined by observing each participant's interactive behavior for 36 minutes distributed over three …

The Relationship Of Role Organization And Role Deprivation To Nurses' Views Toward The Requirement For Entry Into Professional Practice And Its Related Issues, Paula G. Morton

Dissertations and Theses

A national resolution to alter the educational and practice requirements for nurses by 1985 has been adopted in Oregon. It has been theorized that how nurses organize their multiple roles and the degrees of role deprivation they experience will affect their views toward professional issues. Prior research suggests there be a relationship between certain demographic variables and nurses' role organization and role deprivation.

The study sought to establish the relationship of selected demographic variables and the variables of type of role organization and deprivation to nurses' views of four facets of the 1985 Resolution. The intent was to examine the …

The Copper Complexation Properties Of Dissolved Organic Matter From The Williamson River, Oregon, Charles Russell Lytle

Dissertations and Theses

Recent research has indicated that dissolved organic matter (DOM) may plan an important role in the ability of natural waters to complex metals. This research was conducted because the quantitative nature of this role is uncertain. Gas-liquid chromatography was used to study the hydrolyzable amino acids at twelve sampling sites on the Williamson River at monthly intervals for two years. The relative abundances showed little spacial or temporal variation. The two-year averages for total amino acids ranged from about 0.5 (mu)M to about 8 (mu)M. A separation technique was used to show that (GREATERTHEQ) 96% of the dissolved amino acids …

Temporal And Phenomenological Aspects Of Social Behavior In Captive Wolves (Canis Lupus L.), Paul C. Paquet

Dissertations and Theses

Although cooperative behavior is generally acknowledged to occur among wolves, there is a lack of systematically collected data confirming the extent of development. The objectives of this study were to collect long-term, detailed observations documenting the role of social structure, seasonal influences, and individual participation in wolf pack cooperative activities. Individual cooperative strategies were associated with age, sex, and social positions and critically compared with results of similar studies. Emphasis was placed on quantifying group and dyadic relationships, focusing on reproductive strategies and dominance structure. Additional data were collected on denning behavior, maternal care behavior, scent marking, and spontaneous individual …

Community Structure On The Urban Frontier: The Jews Of Portland, Oregon, 1849-1887, Robert Scott Cline

Dissertations and Theses

No other ethnic group enjoyed the level of success, defined in terms of economic status and social acceptance, attained by Portland Jews in the second half of the nineteenth century. Hailing predominantly from the German states of northern and central Europe, the Jewish pioneers transplanted middle class values and mercantile skills in their new home. From a small unstable population of single men in the 1850s, Portland Jewry grew into an affluent class conscious family oriented community by the mid-1880s.

The center of Portland's Jewish life during the formative years was Congregation Beth Israel, the first congregation in the Pacific …

The Coming Of The Birdman: The Aviator's Image In Oregon, 1905-1915, Patrick John Harris

Dissertations and Theses

Between 1905 and 1915 the aeroplane was tested at exhibitions and became a practical machine. Some observers, however, greeted this technological marvel with ambivalence. Skeptics felt that if the aeroplane could alter common perceptions about natural laws, it might also challenge time honored ideals and attitudes about the nature of man.

In response, newspapers and magazines fashioned the aviator's image. The aviator was daring yet responsible, romantic yet reasonable.

Some writers and reporters believed that an aviator's self-confidence and high moral character contributed to control in the air. By controlling the aeroplane with mastery and grace, an aviator remained master …

Affective Perspective-Taking And Sympathy In Young Children, Mary Driver Leinbach

Dissertations and Theses

The present study focused upon both behavioral and cognitive aspects of sympathetic responses in preschool children. Subjects, 36 boys and girls aged 33-75 months, were seen at their regular day care center. An attempt was made to promote comforting behavior through the use of a peer model both alone and accompanied by an adult's inductive statement regarding the consequences of a sympathetic response; a six year-old girl served as the sympathetic model and as an apparently injured victim in need of comforting. In addition, age- and sex-related relationships for the measures of social cognition, affective perspective-taking and knowledge of strategies …

The Effect Of Early Handling On The Sexually Dimorphic Rate Of Extinction Of A Conditioned Taste Aversion In Rats, Rebecca Lee Yoder

Dissertations and Theses

Male rats have been found to extinguish a conditioned taste aversion slower than females. It has also been found that female rats that have been "handled" (i.e., exposed to daily brief isolation from siblings and mother) during the preweaning period extinguish a taste aversion faster than nonhandled females. The present study sought to combine and extend these findings by testing handled and nonhandled females and males in a conditioned taste aversion under the methodological conditions used in the sex difference research.

The Determination Of A Relative Chronology For A Surface Archeological Site Using The Obsidian Hydration Dating Method, Scott Preston Thomas

Dissertations and Theses

This methodological study is an attempt to develop relative chronologies for surface archaeological sites from the obsidian hydration analysis of waste flake samples. Two sites in southeastern Oregon were selected and their surface components sampled. The results of the obsidian hydration analysis indicate, that with the use of random sampling methods and general geochemical control, a fairly accurate representation of the history of an archaeological surface site can be obtained.

Chemistry Of Chromium Oxyfluorides And Group Vib Perfluoroglutarates, Bruce Michael Johnson

Dissertations and Theses

Pure chromium oxide trifluoride was prepared for the first time by reaction of CrO₃ and ClF with subsequent multiple fluorine treatments at 120°C. On the basis of its infrared spectrum, the purple CrOF₃ was assigned as a fluorine-bridged polymer with terminal oxygen groups. Chromium oxide trifluoride was found to be stable to 300°C, where it decomposes with the loss of oxygen to CrF₃.

A Comparison Of Two Articulation Carry-Over Techniques, Robyn Schwartz

Dissertations and Theses

The purpose of this investigation was to determine the comparative effectiveness of two articulation carry-over techniques. It was hoped that through this comparison answers regarding carry-over results could be ascertained for purposes of aiding public school clinicians currently spending the majority of management time on carry-over. If one technique was found to be superior, its use among speech pathologists might aid in changing this time allocation trend.

A History Of The Portland Waterfront Between Southwest Clay And Washington Streets, Its Land Use And Legal Problems, Jeffrey Gerald Carter

Dissertations and Theses

Between 1845 and 1980 the Portland waterfront between southwest Washington and Clay Streets, east of Front Street, metamorphosed from wilderness to trade center, to highway, to inner-city vacant lot. No place in Portland has more graphically illustrated the rapidly changing forces of the modern age in which the city has grown.

For much of its history this stretch of waterfront was mired in law suits. The struggles centered on public versus private ownership. Originally dedicated as public property, but left unimproved by the city, the waterfront was usurped by private investors. Eventually, private owners allowed their property to decay prompting …

Anna Held: A Biography, Michael Owen Hoffman

Dissertations and Theses

This thesis, a biography of the French actress, Anna Held (1873-1918), is an attempt to place her in proper perspective in American history. Essentially a record of Miss Held from birth to death, it highlights many events that made her famous. Included are examples of publicity generated by her manager-husband, Florenz Ziegfeld, Jr.

Much credit can be awarded Ziegfeld for his expertise in publicity stunts and promotion. Undue praise, however, has been attributed to him for the origin of the Ziegfeld Follies and the success of Anna Held.

Anna was a Continental success long before she met him. His promotion …

Trouble In River City: An Analysis Of An Urban Vice Probe, Joseph S. Uris

Dissertations and Theses

This dissertation is an historical case study of a highly publicized investigation of vice and official corruption which took place in Portland, Oregon from 1954 to 1958. Three major relevant areas of social science literature are reviewed. These are: historical material on American reform and corruption, criminology and political science. This literature suggests both the ubiquity and usefulness of vice and corruption in the urban situation.

A set of propositions regarding vice, corruption and reform was developed from these works. These propositions were then examined in terms of the vice probe and political situation in Portland, Oregon.

A Genetic And Physiological Study Of An Arsenite Resistant, Uncoupled Mutant Of Escherichia Coli, Daniel Gordon Smiley

Dissertations and Theses

Chromosomally determined arsenate resistance in Escherichia coli is well characterized. Little, however, is known about chromosomally determined arsenite resistance in E. coli. Accordingly, spontaneous arsenite resistant mutants were selected in a plasmid free strain of E. coli. One mutant strain was analyzed in detail, genetically and physiologically. The mutation confering arsenite resistance was shown to be a single gene mutation. Genetic mapping studies using conjugation and transduction showed that the mutation was closely linked to the ilv region of the E. coli map.

Physiological studies of this mutant showed that it shared characteristics common to those of mutants …

Factorial Structure Of The Hamilton Rating Scale For Depression, Kevin Page O'Brien

Dissertations and Theses

The Hamilton Rating Scale for Depression (HRS), a 17-item observer-rated scale, was first developed in 1960 to assess the severity of depressive symptomatology in patients diagnosed as suffering from depression. The HRS has since demonstrated high inter-rater reliability (with coefficients ranging from .87 to .94), and has proven useful in measuring changes of severity following treatment.

Since its development, the HRS has been the focus of several factor analytic investigations, four of which attempted to assess the instrument for factorial invariance. Factorial invariance refers to the generalizability or applicability of dimensions developed from one sample to another. While some consensus …

Burnout: Multi-Dimensional Study Of Alienation Among Social Service Workers In The Willamette Valley, Sally Carignan

Dissertations and Theses

In a profession such as social work, where one is responsible for dealing with the ills of society and meeting the needs of other individuals, such emotional detachment and estrangement from others is antithetical to the purpose of the field and eminently destructive to those seeking and needing assistance. With the current push for accountability, factors such as burnout or alienation from one's work become of crucial importance. In addition, burnout leads to a high rate of absenteeism and job turnover (Minihan, 1980). This too decreases cost effectiveness and the quality of service, matters of extreme concern in a field …

Geology Of A Volcanic Complex On The South Flank Of Mount Jefferson, Oregon, Brian Lee Gannon

Dissertations and Theses

The volcanic stratigraphy and petrography is described for a 46 km² area on the southern flank of Mount Jefferson in the north-central part of the Oregon High Cascades. Here, volcanic processes have been active throughout Quaternary time, resulting in complex stratigraphic relationships. In addition, three formerly recognized glaciations and a two-phase period of neoglaciation have eroded the terrain, depositing tills in contact or interstratified with the volcanic units. Collectively, these processes and the resulting deposits are characteristic of High Cascades development.

Non-Work-Related Services At The Workplace: An Exploratory Study, William Roland Adix

Dissertations and Theses

In an era of diminishing public funds, the profession of social work is looking more and more toward the private sector as an arena for social work practice. Social work has had a long-standing interest in the impact of work and the workplace on the individual. This study was developed in response to the lack of documentation of non-work-related services in Oregon's businesses and industries. The research team set out to discover what non-work-related services are available to employees at or through the workplace in the TriCounty area (Multnomah, Clackamas, and Washington Counties) of Oregon. This study was exploratory, similar …
