A Comparison Of Depression In Males And Females After The Loss Of A Spouse, Thomas N. Dejong

Theses

The purpose of this research was to explore differences in depression between males and females after the loss of a spouse. After a review of the literature, a twenty-one item inventory, the Beck Depression Inventory was given to thirty nine surviving spouse's (17 males and 22 females). AT-test of difference between means of the three factors of the Beck Depression Inventory, (negative self-attitudes, physiological symptoms, and sadness) was performed and the hypothesis that there were differences in depression between males and females after the loss of a spouse was not supported.

Therapist Orientation And Circularity-Linearity Of Causality, Responsibility, Intentionality, And Blame For Clinical Problems, Helen Alexander Jones

Psychology Theses & Dissertations

Differences in circularity of attributions of causality, responsibility, intentionality and blame for clinical problems by therapists of psychodynamic, behavioral and systems orientations, a psychiatrist group, and an attorney control group were investigated using the Circularity-Linearity Attribution Scale (CLAS). Respondents' judgments about the sufficiency of a single cause for the problem, circular conceptualization of the problem, and linear conceptualization of the presented problems were also solicited. Responses were compared for two problems, schizophrenia and domestic violence. It was hypothesized that the systems-oriented therapists' attributions would be more circular than those of other therapist groups on all dependent variables. It was also …

Application Of Reanalysis Techniques For Pattern Design Of Spot Welds, Young San Kim

Mechanical & Aerospace Engineering Theses & Dissertations

Extensive benchmarking on competitive cars has shown that the durability of vehicles, assembly-induced variations, and assembly cost are directly related to the quality and number of spot welds. On most luxury cars, approximately 4,500 to 5,000 spot welds are found. On less expensive cars, the range is from 3,500 to 4,500. These cars usually inherit more noise, rattles, squeaks, and other quality-related problems. These problems have motivated the search for a new capability to systematically place welds in the most critical areas, with a minimum number of welds for car bodies, while satisfying all performance requirements (e.g., stiffness, stress distribution, …

A Watershed Issue: The Role Of Streamflow Protection In Northwest River Basin Management, Reed D. Benson

Faculty Scholarship

Watershed management has become a popular approach to environmental problems in the Northwest. Federal, regional, state, local, and tribal watershed efforts are in progress throughout the region. The popularity of the watershed approach can be traced to ecological and political factors. Most watershed management activities, however, focus more on land use and riparian measures than on providing and protecting instreamflows. For both legal and political reasons, watershed efforts tend to avoid water rights issues. Such efforts tend not to be well connected with instream flow protection or water resource planning under state law. Unless they address the need for streamflows, …

Voices/Voces In The Borderlands: A Colloquy On Re/Constructing Identities In Re/Constructed Legal Spaces, Margaret E. Montoya, Melissa Harrison

Faculty Scholarship

While we believe that the work of healing our cultural dyslexia is partly cognitive, in and through this paper we have tried to enact the experiential aspect. We may approach the entrances of the borderlands through reading and thinking, however we believe that the borderlands is a phenomenon of living, a phenomenon of well-intentioned people interacting in deliberate and thoughtful ways with those who are simultaneously like and unlike us/them. The borderlands require that we bring our critical faculties to bear on life's experiences, but, more often than not, we must suspend them in favor of more charitable and affiliative …

Rn And Lpn Perceptions Of Front-Line Delegation, Martha E. Colwell

Dissertations and Theses @ UNI

Healthcare organizations face increasing demands to provide the most efficient and economical care possible. Emerging patient care delivery systems require that front-line RNs take on a broader scope of responsibility for patient care, particularly in the area of delegation. Research identifies that staff RNs experience much difficulty in delegating patient care (Conger, 1993; Hansten & Washburn, 1994). The purpose of this study was to explore RN and LPN perceptions of front-line delegation in their working relationships. In particular, the study sought to: (a) determine how changing roles of RNs and LPNs influenced front-line delegation; (b) answer how RNs viewed front-line …

The Effects Of Herbicides On Microbial And Mycorrhizal Populations In Native Prairie, Corn, And Non-Native Prairie Vegetation, Using The Biolog Technique, Susann E. Ahrabi-Fard

Dissertations and Theses @ UNI

Soil bioremediation has primarily focused on the use of free living, actively growing microorganisms to degrade toxic organic substances. Recently, however, plants and rhizosphere activity, including mycorrhizal fungi have been increasingly studied to determine the role that consortial assemblages may play in bioremediation. While the enhanced absorbtion of nutrients, water, and minerals by mycorrhizal fungi has been well documented, less is known about their role in the degradation of soil contaminants. Using the Biolog plate technique, microbial communities were characterized in Native Prairie, Corn, and Non-Native Prairie vegetative strips prior to, and after two applications of Acetachlor, Alachlor, and Atrazine. …

The Women Superintendents Of Iowa: A 1990'S Analysis, Joen M. Rottler

Dissertations and Theses @ UNI

Historically, Iowa has had few women superintendents of K-12 public schools. Societal changes, political changes, and legislation, such as affirmative action, have had no impact on gender balance in the superintendency in Iowa. The number of women superintendents in Iowa remains low. Of 397 superintendents in Iowa, during 1993-94, only 14 were women. This qualitative study examines the characteristics of current women superintendents of Iowa. Specifically, the following aspects of career development were examined: childhood and adolescent characteristics, personal and professional characteristics, and career path. The experience of being a woman superintendent and gender related aspects of leadership were also …

Design And Evaluation Of An Environmental Science Curriculum For Secondary Students, Carolyn Knox Cooper

UNF Graduate Theses and Dissertations

Environmental education is becoming an increasingly important component of secondary science education as our society attempts to minimize the exploitations and damaging actions of humankind on the earth. Environmental education has evolved primarily from environmental consciousness in the 1960s to an environmentally active focus in the 1990s. This project examined the effectiveness of an environmental education curriculum that focuses on improving environmental behaviors and attitudes as well as knowledge.

The review of the literature for this project indicates that responsible environmental behaviors are linked to four types of environmental education categories. These categories are hierarchical and include: 1) ecological concepts, …

Coping Strategies And Adaptation Mechanisms Utilized By Female Holocaust Survivors From The Auschwitz Concentration Camp, Joy Erlichman Miller

Harold L. Hodgkinson Award for Outstanding Dissertation

The female experience during the Holocaust has largely been ignored as significantly different than that of male counterparts. This gender-specific research study investigates the "unique, poignant voices" of women's coping strategies utilized during internment in the Auschwitz Concentration Camp.

Focusing specifically on the video oral history testimonies of the complete collection of female survivors of Auschwitz, which were produced by the United States Holocaust Memorial Museum, the study suggests that the predominate coping strategies used by females was affiliation with others as the means of survival. Through the utilization of clustering sheets, the data suggested that affiliation and assistance from …

A Content Analysis Study Of Portable Assisted Study Sequence Mathematics Curricular Materials For Migrant Students Using The National Council Of Teachers Of Mathematics Standards, Karen I. Conger

Harold L. Hodgkinson Award for Outstanding Dissertation

The need for change in the mathematics curricula in our public schools has been well documented (Kirwan, 1990; National Commission on Excellence in Education, 1983; National Research Council, 1989; Overby, 1993). Testing surveys show low overall performance at every age throughout the K-12 levels. The Curriculum and Evaluation Standards for School Mathematics, (Standards) issued by the National Council of Teachers of Mathematics (NCTM) in 1989 are designed to move mathematics curricula forward to meet the needs of students for the future. The analysis of new curricular materials is essential in order to produce materials that meet recommended standards.

Influence Of Physical Fitness On Susceptibility To Noise-Induced Temporary Threshold Shift In Females, Stacy Claire Bukatz

Dissertations and Theses @ UNI

This study investigated the influence of physical fitness on susceptibility to noise-induced temporary hearing loss in 33 females of various fitness levels, and the relationship between temporary threshold shift (TTS) and distortion product otoacoustic emission (DPOAE) measurements. Behavioral audiometric thresholds and DPOAE measurements were obtained at 2000, 3000, 4000, and 6000 Hz prior to and immediately after 10 minutes of exposure to 108-dB SPL narrow-band noise centered at 2000 Hz. The greatest TTS and largest reduction in DPOAE amplitude occurred at·3000 Hz. However, no significant correlation was observed between TTS and DPOAE at any frequency or between any of the …

Potential For Controlling The Spread Of Centaurea Maculosa With Grass Competition, John L. Lindquist, Bruce D. Maxwell, T. Weaver

Department of Agronomy and Horticulture: Faculty Publications

ABSTRACT.-Spotted knapweed (Centaurea maculosa Lam.) is a major rangeland and roadside weed of the northern Rocky Mountains. It is often found in plant communities dominated by Pseudoroegneria spicatum or Festuca idahoensis, but it rarely invades roadsides dominated by Bromus inerrnis Leyss. Aboveground biomass of the 3 grass species grown in mixture with Centaurea was compared to growth in monoculture at a range of nitrogen input levels. The results suggest that Bromus is capable of suppressing the growth of Centaurea with the degree of suppression increasing with increasing nitrogen levels. The 2 native grasses had no impact on Centaurea …

Breeding Sorghum And Pearl Millet For Forage And Fuel, Jeffrey F. Pedersen

Department of Agronomy and Horticulture: Faculty Publications

Sorghum [Sorghum bicolor (L.) Moench] and pearl millet [Pennisetum glaucum (L.) R. Br.] are unique species in their ability to be used in many forage llivestock system roles. Such flexibility has made prioritizing breeding objectives difficult and has even contributed to contradictory opinions on appropriate forage breeding objectives. Few breeding projects identified in the USDA-ARS, USDA-CREES, or at ICRISAT had forage sorghum or forage pearl millet as their sole research assignment. In the United States, it can be argued that breeding resources committed to forage sorghum improvement are probably declining. A new forage sorghum and forage pearl millet …

Germplasm And Cultivar Development, M. D. Casler, Jeffrey F. Pedersen, G. C. Eizenga, S. D. Stratton

Department of Agronomy and Horticulture: Faculty Publications

Cool-season forage grasses have evolved, and continue to evolve, in natural ecosystems subject to environmental factors both in the presence and absence of human influences. The literature often lacks facts describing the evolution and domestication of forage grasses. Furthermore, the literature on this subject mainly deals with evolution of species in the broad scope, i.e., on a scale of hundreds of thousands or millions or years. Thus, some of our conclusions are necessarily speculative and are highly subject to the nature of the research that has been reported. We describe the forces of selection that act upon cool-season forage grasses …
