    • Qualitative aspects of memory performance in depressed versus demented elderly

      Kaszniak, Alfred W.; Nussbaum, Paul David, 1963- (The University of Arizona., 1987)
      This study investigated quantitative and qualitative aspects of memory in three age-and-education-matched groups (1) 38 normal elderly, (2) 15 patients with dementia of the Alzheimer's type (DAT), and (3) 26 depressed elderly. Three clusters of dependent variables were used to examine group differences: (1) standard psychometric (Wechsler Memory Scale logical memory and visual reproduction subtests), (2) verbal recall measures (free recall measures of primary memory, secondary memory, prior item intrusions and extra list intrusions), and (3) verbal recognition memory measures (true positive, false positive, true negative, and false negative responses). Analyses of variance, with specified contrasts, found the DAT patients to demonstrate a pervasive memory impairment affecting both the qualitative and quantitative memory indices compared to depressed and normal elderly. The depressed elderly demonstrated impairment, compared to normal elderly, on tasks requiring effortful processing. Findings support pervasive memory loss in DAT patients and do not support clear memory impairment in the present depressed sample.

      Haugebak, Clayton Deane, 1946- (The University of Arizona., 1970)
    • A qualitative evaluation of multicultural art curricula at primary levels

      Greer, W. Dwaine; Borin, Meredith Dawn, 1971- (The University of Arizona., 1997)
      Today, a large number of multicultural publications and resources are available for elementary classroom use. The purpose of the study was to examine existing multicultural elementary art curricula and resources to evaluate their adequacy and availability to the classroom art teacher, according to criteria, methods, and materials recommended by scholars in art education. The examination included price range and adaptability of material, audiovisual resources, art production, art criticism, art history, aesthetics, sequential organization, developmental appropriateness, cultural integrity, and multicultural content level. Upon completion of this study, two of the five curriculum publishers proved to consistently produce multicultural art education curriculum at a high quality level. Crizmac and Crystal Publications offer a number of curriculum settings that comply with current NAEA standards as well as the criteria set forth in this paper. Supplementary resources and the future of multicultural art education in respect to curriculum and classroom implementation are also discussed.

      Hartman, Robert Smith, 1940- (The University of Arizona., 1966)
    • A Qualitative Exploration of Entrepreneurial Learning among Local Farmers in Cochise County, Arizona

      Mars, Matthew; Zamudio, Jessica Maria; Torres, Robert; Astroth, Kirk (The University of Arizona., 2015)
      The number of farmers markets in the United States increased from 3,706 in 2004 to 8,268 in 2014 (Agriculture Marketing Service, 2014). Often times, small-scale agricultural producers do not harvest enough goods to be sold in large grocery store corporations and thus have turned to farmers' markets, roadside stands, you-pick operations, and community supported agriculture (CSA) shares as pathways for reaching customers directly (Chase & Winn, 1981; Payne, 2002). The purpose of this study was to explore and describe how such small-scale producers who participate in farmers' markets gain and develop business-related information and business skills. A single case study design developed and applied to explore the entrepreneurial learning environment relevant to small-scale agricultural producers in Cochise County, Arizona. The current study is framed conceptually by Politis's (2005) entrepreneurial learning model. The data was collected through semi-structured interviews, observations, and relevant documents. Data was organized and analyzed both ideographically and nomothetically. The findings indicate that some small-scale agricultural producers who reside in Cochise County, Arizona participate in Southern Arizona farmers' markets for economic viability and/or lifestyle reasons. The producers who participate in Southern Arizona farmers' markets as their sole means of generating income and/or to continue to be able to afford their engagement in agricultural activities were categorized under the economic viability theme. Those producers who participate in Southern Arizona farmers' market primarily to socialize and to exchange knowledge with community members and other farmers or ranchers were categorized under the lifestyle theme. The data also revealed that the participants engaged in entrepreneurial learning primarily within informal settings and through corresponding channels. While, informal learning is likely to remain the primary method of knowledge sharing across the small-scale agricultural producer community in Cochise County, Arizona. However, by providing such producers with greater opportunities to develop deeper and more robust knowledge and skills specific to entrepreneurship and small business development and management through non-formal learning opportunities (e.g., innovative Extension program), the number of producers with enhanced training capacities and cutting edge knowledge will increase across Cochise County.
    • Qualitative generation of wellness motivation theory: A secondary analysis

      Gerber, Rose M.; Burke, Jennifer Marie, 1962- (The University of Arizona., 1992)
      The purpose of this study was to provide a secondary analysis of Derenowski's inductively generated conceptualization of wellness motivation, specifically the category identifying barriers. The sample consisted of 29 individuals who were attempting to initiate and sustain programs of cardiac risk factor modification. Descriptions of perceived barriers to initiating health behavior change were generated from the data using grounded theory methodology. Categories identified within perceived barriers to initiating health behavior change included: personal control, life stress, social relationships, physical capability, and resources. The descriptions of perceived barriers to health behavior change generated from the data provide an understanding and theoretical basis for nursing assessment and the development of interventions designed to assist individuals in continued growth and the emergence of positive health patterns.
    • Qualitative simulation: A tool for global decision making

      Cellier, Francois E.; Vesanterä, Pentti Juhani, 1955- (The University of Arizona., 1988)
      As a decision making aid for the human operator of a highly automated, complex system, qualitative modeling is presented as a tool to mimic the human global assessment process by learning from the system behavior. Such qualitative model is applied to reason about the behavior of a quantitatively simulated aircraft model, to determine on-line when a malfunction occurs in the quantitative model, to hypothesize about the nature of this malfunction, and to suggest a global strategy that would allow to operate (control) the quantitative aircraft under the modified flying conditions. Such an algorithm could be utilized as an addition to a conventional autopilot which would allow it to remain operational after a malfunction has taken place.
    • A qualitative test for phenols

      Johnson, Gordon Barker, 1920- (The University of Arizona., 1947)
    • Quality assurance for the clinical ferromagnetic seeds project

      Cetas, Thomas C.; Sinno, Rami Assem, 1964- (The University of Arizona., 1989)
      Surgically implanted thermoregulating ferromagnetic seeds as a mean of inducing hyperthermia in malignant tumors has been successfully introduced in a clinical environment at the University of Arizona. This work covers topics in quality assurance for the method on two levels. The first level deals with the magnetic induction system where magnetic and electric fields are measured. A discussion on safety levels for patients and treatment personnel is given, and an optically coupled probe for magnetic field measurements is described. The second level treats the electrical characteristics of the ferromagnetic seeds. Systems to measure the permeability and conductivity of the seeds are presented with some typical results. Finally, hysteresis power loss in a seed is measured and compared to losses due to eddy currents.

      Woodard, Gary C.; Maddock, III, Thomas; Rupprecht, Candice Lea; Woodard, Gary C.; Maddock, III, Thomas; Jacobs, Katharine (The University of Arizona., 2009)
      Scientists now recognize how quickly environmental conditions are changing, yet to monitor and understand these spatially distributed changes more dispersed quantitative and qualitative data are needed than ever before. The need for more comprehensive and robust data has created the burgeoning field of citizen science, which engages volunteers to monitor environmental changes and report this information to scientists. Precipitation monitoring networks like are considered one of the oldest types of citizen science with many networks in existence for over 100 years. is a more modern version of these original networks and was developed in response to a need to better characterize precipitation events and provide stakeholders with more robust precipitation totals and distributions throughout is a statewide precipitation monitoring network that relies on volunteers across Arizona to report daily precipitation into an online reporting system. To ensure that these data are reliable, a quality assurance and quality control analysis (QA/QC) was completed on a subset of gauges in the Tucson area. Results indicate that although there are many errors inherent with any precipitation network, whether volunteer or scientist driven, these errors are for the most part identified using basic interpolation methods. This paper analyzes a range of user reporting and gauge type errors, discusses the significance of each error type and provides recommendations for mitigating reporting errors in any citizen science network.

      Bartkowski, Laura Briggs, 1952- (The University of Arizona., 1978)
    • The quality of drug prescribing in a multinational medical setting

      Larson, Lon N.; Al-Dhewalia, Hamad Mohammed, 1955- (The University of Arizona., 1988)
      The objectives of this study were to investigate the hypotheses that: (1) Job satisfaction is related to medical specialty, the physician's nationality, and length of tenure. (2) The physician's attitude toward the Drug Utilization Review (DUR) program is related to medical specialty, the place of residency training, length of tenure, and job satisfaction. (3) The quality of drug prescribing is related to medical specialty, the place of residency training, length of tenure, job satisfaction, and the physician's attitude toward the DUR program. The results indicated a significant relationship between the physician's nationality and job satisfaction (P = 0.001), and between job satisfaction and the physician's attitude toward the DUR program (P 0.001). Medical specialty was a strong independent predictor of the quality of drug prescribing (P = 0.002). However, the other independent variables of the locale of residency training, length of tenure, job satisfaction, and the physician's attitude toward the DUR program were not related to drug prescribing.
    • Quality of life and human becoming for persons with end-stage cardiac disease

      McGaffic, Cheryl M; Wood, Theresa Marie (The University of Arizona., 1998)
      The Parse research method of phenomenology was used to explore the universal lived experience of quality of life for end-stage cardiac patients. Four individuals with terminal cardiovascular disease, who were enrolled in hospice, participated in a dialogical engagement. The audio taped dialogical engagements were analyzed utilizing Parse's procedure of extraction-synthesis. Three core concepts emerged to formulate a structure of the lived experience of quality of life. The concepts identified were: Coherence with others creates meaning; Integration of life essences from past-present-future; and Struggling with limitation-limitlessness emerges transformation. The structure was linked to the Human Becoming Theory and beyond through a process of heuristic interpretation. The findings from the study produced new knowledge and understanding regarding the human experience of quality of life.
    • Quality of life following heart transplantation

      Kaszniak, Alfred W.; Chatel, Daniel Mark, 1957- (The University of Arizona., 1989)
      With improved survival following cardiac transplantation, attention has focused upon the quality of that survival and some of the variables that may impact quality of life. The present study objectively measured subjective aspects of quality of life in order to discover its pre- and postoperative predictors. Results indicate that immunosuppression following heart transplantation creates a significant number of complications and symptoms for the recipient and is significantly related to elevated levels of psychological distress, particularly depression and anxiety, and decreased self-esteem. These findings emphasize the importance of careful symptom evaluation and targeting of distressed patients for psychological intervention in clinical settings and underscore the importance of continued medical research to improve immunosuppression therapy. Descriptive statistics reveal a rather mixed picture of postoperative quality of life which may result from the difficult clinical reality in which heart transplant patients often trade one set of preoperative cardiac symptoms for another set of postoperative symptoms related to immunosuppression therapy.
    • Quality of life following laparoscopic fundoplication for the treatment of gastroesophageal reflux disease (GERD)

      Parsons, L. Claire; McNeil, Kathryn Lynn (The University of Arizona., 2000)
      The purpose of this study was to explore the perceived quality of life of persons following laparoscopic fundoplication surgery for the treatment of gastroesophageal reflux disease (GERD). A secondary purpose was to explore the experience of gastrointestinal symptoms of persons following laparoscopic fundoplication surgery for the treatment of GERD. The Gastrointestinal Symptom Rating Scale (GSRS) was used to assess the perception of gastrointestinal symptoms and the Medical Outcomes Study Short Form 36 (SF-36) instrument was used to assess the subjects' perception of quality of life. A convenience sample of 20 subjects was recruited from one gastrointestinal surgical practice. Data analysis included descriptive statistics, analysis of variance (ANOV A), t-tests, and Pearson product-moment correlations. Results indicated that the subjects in this study who had undergone laparoscopic fundoplication for the treatment of GERD experienced a slight level of discomfort due to gastrointestinal symptoms and perceive themselves as having a moderately decreased quality of life. Differences were found between those subjects who had received a Nissen (complete wrap) fundoplication procedure and those who had received a Toupet (partial wrap) fundoplication procedure, with the Toupet group having statistically significant (p<.05) better scores on all subscales of the GSRS and on the social functioning, bodily pain and role functioning-emotional subscales of the SF-36. Nursing implications included assessment of multiple systems and promotion of quality of life in providing holistic care to the GERD client.
    • Quality of life in women post-myocardial infarction : the relationship of health promoting behaviors with enrollment and attendance in a cardiac rehabilitation program

      Berg, Judith A.; Sharifi, Agnes Marie (The University of Arizona., 2001)
      The purpose of this study was to describe the relationship between quality of life (QOL) scores in post-AMI women who attend cardiac rehabilitation program (CRP) and women who do not attend. QOL scores were measured by the use of the modified Woman's Health Questionnaire and the MacNew QOL Questionnaire. A non-probability sample of women was obtained who were diagnosed with acute myocardial infarction (AMI) based on ( a) elevated cardiac enzymes, (b) electrocardiogram (EKG) changes of a significant nature, ( c) AMI diagnosis at least 8 weeks from study but no more than 1 year from study date, and ( d) English proficiency. Women were not excluded due to history of previous AMI. The Internal Review Board at Northwest Hospital in Tucson, Arizona approved a medical record review to contact their previous patients who met the criteria for inclusion. The sample of 30 women obtained had a mean age of 65.23 years (range 33-87), a majority were married, with a current relationship being spousal, a total income of greater than $50,001 per year, with Medicare as their primary insurance. Comorbidities included heart disease (100% ), followed by diabetes mellitus, osteoarthritis, and thyroid disease. Medications correspond to chronic diseases listed. The women studied did not exhibit any significant differences on QOL scores regarding enrollment or non-enrollment in CRP, attendance or non-attendance in CRP, nor was significance found in the relationship between QOL scores and attendance at CRP. Other findings suggest that those women with greater education were more likely to attend greater than 2 sessions of CRP. Number of medications used also showed high correlational value with attendance at greater than 2 sessions of CRP. A significant relationship was found that with an increased number of comorbidities, QOL scores declined. The use of the MacNew QOL Questionnaire proved high internal consistancy, reliability for the total instrument and its subscales for this sample. Results of this small study showed no significant differences in post-AMI women and their QOL scores regarding attendance at CRP, illustrating a need for further nursing research. Advocating health promoting behaviors is essential for nursing to promote QOL in women who have experienced AMI.
