    • Relevant Role Activities, Educational Preparation and Self-Perceived Competence of First-Level Nurse Managers in Taiwan

      Chen, Justina Huey-Tzy; Department of Nursing (1987-04)
      The purpose of this descriptive coo relational study was to determine the critical-role activities of head nurses in Kaohsiung City hospitals, Taiwan, R.O.C., and the adequacy of their educational preparation for and competence in enacting their roles. The subjects consisted of 29 head nurses who are currently functioning as first-level managers on inpatient units in five Kaohsiung City hospitals. The role activities section ( 41 items ) of The Nurse Administrator Role Activities And Administrative Knowledges ( NAKAAK) Questionnaire was used for data collection in this study. The mean scores for each role activity - associated with a nurse managers role, were used to determine the relevance of, preparation for, and competence in performing first level management roles. Thirty-two role activities were rated by the subjects as most relevant role to th~ir enactment. They identified only one activity for which they perceived they were well prepared. They rated themselves very competent, however, in the performance of 35 of total 41 role activities. Pearson Product-Moment correlation coefficients were used to determine the·.relationships between their preparation and relevance, relevance and competence, and competence and preparation ratings. Moderate correlations were found between their preparation for and the relevance of 13 role activities. High correlations were found between the relevance of and competencein the performance of 1 0 role activities and moderate coo relations for-29. Moderate eorrelations between competence in the performance and preparation for were found for 14 role activities. The Chi-Square test was employed to test the relationships between - selected personal factors ( age, education, and tenure ) and their self perceived competence. Signifi"cant differences were found between nursing education and self perceived competence for eight activities. Several recommendations for further studies were drawn including the need for ongoing revision and updating of head nurses' job descriptions to reflect the changing reality of their role requirements and the need for ongoing managerial staff development and continuing education for head nurses. In addition, it is recommended that the NARAAK instrument used in this study be further tested by retesting the same sample group in fo_ur months. It will then be possible to achieve an estimate of reliability of the instrument for use in Taiwan.
    • A Transforming Growth Factor From MCG-T14 Mouse Mammary Carcinoma Cells

      Cheng, Charles; N/A (1983-04)
      Mitogenic activity was assayed in the harvest fluid concentrates (HFC) from. human· mammary cell.lines ·(T47P, HSO 578T, MDA-157, HBL-100 and BT-20) and a mouse mamamry carcinOinii (MCG-T14) cell line. Data showed that the HFC from four of the human cell lines (T47D,.HSO 578T, MDA-157, and HBL-fOO) and the mouse cell line (MCG-Tl4) were sour.ces of mitogenic activity. The mitogenic activity from the HFC was not due to the action of the serine protease, plasminogen activator. The mitogenic substance was also not a cell degradation product. The HFC from the human mammary carcinoma line BT-20 contained a non-dialyzable inhibitory activity which su~pressed the activities of the mitogerts in fetal bovine serum. Attempts to isolated the mitogenic activity from HFCs proved impractical due to proteolytic breakdown. However, a transforming growth factor (TGF) from acid-ethanol extracts of MCG-T14'mouse mammary carcinoma ' ' cells was isolate~ and·partially characterized. This factor stimulated thymidine uptake in BALB/c 3T3 cells and promoted anchorage-independent growth of NRK-49F cells in soft agar. The mitogenic activity, designated T14-TGF, stimulted thymidine uptake in conflue.nt-quiescent BALB/c 3T3 cells to the same extent as tha,t exhibited by 5% calf serum. T14-TGF was potentiated by EGF in its ability to promote colonial growth of NRK-49F cells. In competition binding assays, T14-TGF and EGF competed for binding to BALB/c 3T3 and A431 cells. However, EGF was a more efficien~ competitor than T14-TGF in all experiments and T14-TGF exhibited only partial inhibition of EGF-binding to A431 cells. This suggests that T14-TGF may have contained subfractions which did not compete for EGF binding sites. Nerve growth factor, fibroblast growth factor, and multiplication stimulating activity did not compete with T14-TGF for binding .. 1 sites .on BALB/c 3T3 cells. In addition, iodinated T14-TGF did not bind to NR6/6 3T3 cells which lack EGF receptors. It was concluded that Tl4-TGF must interact with EGF receptors specifically~ 2 T14-TGF was purified to apparent electrophoretic homogeneity by electroelution from 15% SDS-urea polyacrylamide gelso The factor was basic (pi 8.3), had anapparent moleculaJ; weight of 14,000 and was selectively inactivated by trypsin. In addition, T14-TGF exhibited no proteolytic activity and contained no carbohydrate residues. The biological activity of T14-TGF was resistant to inactivation by acid or heat and· denaturation by guanidine HCl. T14-TGF was completely inactivated by treatment with dithiothreitol which indicated that it required one or more intact disulfide .bridges for activ~ty. A unique characteristic of T14 ... TGF was that this factor bound very strongly to. both DEAE or carboxymethyl f:on excha'Iigers. T14-TGF contained high proportions of basic amino acid residues lys~ne and arginine.

      Chadwich, Jean; Department of Nursing (1984-02)
      The purpose of this study was to examine the neonatal nurses'- knowledge of standards of nursing practice. It was post~lated the degree to which a nurse understands and accepts her professional . accou~ta.bility depend·s :upon her own understanding of her status~ The level of knowledge was obtained from the investigator's selfdesigned tool. Additionally, the study .examined··whether or not a ' . ' ' . difference existed between the knowledge of nu'rses who care for . . . infants who require varying degree~ of 'nursing care, as evidenced by the t:y-pe of hospital ·they are employed in· und~r :regionalization guide~ lines. It further examined the relationship be~ween ·the personal -· variable of type of basic nursing education with the t·otal and subscale scores on the tool. A descriptive--correlational design was ·used to examine the study data generated from· 61 registered nurses, distri~uted _among 15 hospitals in one Southeastern stat_e. Analysis of the study .data using descriptive stati.stics indicated that the neonatal nurses wereknowledgeable of their standards of practice. Pe~rson correlation coefficients revealed no significant difference exis~ed amongst the nurses in Level I,. II _and III neonatal care facilities, nor was there any correlation between the nurses' educational preparation and their level of knowledge of the standards of practice. Additionally~ Pearson correlation coefficients· and Cronhach' s alpha ·were. used to determine the statistic:al validity and ty es-timates of the tool •..
    • Health-Promoting Lifestyles of Women with HIV Disease

      Carr, Rebecca Lamb; N/A (1997-04)
      Women are one of the fastest growing risk groups for HIV infection in the United States, but little is known about how women manage the problems and concerns commonly faced by individuals who are HIV positive. HIV disease results in compromised lifestyles for women as they cope with physiological and psychosocial problems that accompany this disease. The purpose of this focused ethnography was to explore health-promoting lifestyles of women with HIV disease. Research questions guiding this study were: 1) What do women with HIV disease believe they can do to enhance and/or maintain their health after diagnosis? and 2) How do women promote and maintain their health and well-being? Purposive sampling was used to obtain nine European American participants between the ages of 27 and 52 years. These participants were recruited from the southeastern United States. Semi-structured interviews and observation participation were used to obtain data. The majority of participants were interviewed three times. Observation participation occurred during interviews, at conferences; and volunteer group meetings attended by the researcher and the participants. Data analysis was concurrent with data collection enabling the researcher to confirm her interpretations with the participants. Three major themes were identified: 1) Reaching out to others, 2) Searching for meaning, and 3) Buying time. These themes constituted a health-promoting lifestyle that enabled women to adjust to the change in their identity from a healthy person to a person with HIV disease. Initially, women focused on restoring their well-being, but later initiated changes to enhance, maintain, and maximize their health.

    • Marketing Emergency Services: The Degree of Involvement Among Nurse Executives

      Byrd, Lura A.; Department of Physiological and Technological Nursing (1986-05)
      The purpese of this study is to determine the degree of invo1vement among nurse executi~es i~ marketi~g emergency s~rvices. Know1edge ther~by obtained will provide identification of cu~rent marketing.trends in emergency services as wel.l as areas ofmarketing content in education programs preparing nurse executfves. A questionnaire~ 11Emergency Services Marketing Activity Survey 11 (ESMAS)~ specific for marketing e~ergency Services was ·adapted from Kotler•s (1975) 11 Systematic Marketing Audit. 11 Items were dev-eloped far·· each major category (marketing environment; marketing system; and ma·rketing activity}'. purported· by Kotler (1975) to be·essentia1 in eva1uating marketing activities. The ESMAS was reviewed by a panel of fie1d experts including facu1ty invo1ved in teaching marketing and finance in hea)th care services. Based on recommendations from the pane1, severa1 items were revised and made less ambiguous. The revi sed vers i on of the ESMAS Questi onna i re was ma i 1 e.9 to Di rectors of Nurs (DON) and Emergency Department Head Nurses ( EDHN) in 114 Georgia hospitals 1isted by the American Hospital Association Gui de (1985} as· provi ders of emergency servi ces. Study subj ects were asked to respond on a sca 1 e of one to 'seven to .the de·gree to whi eh each marketing emergency services item is a part of their role as nurse executive. Responses were received from 42 DONs and 37 EDHNs. Descriptive information was compi1ed and t-test analysis was done to describe the V involvement of DONs and EDHNs in marketing emergency services and to describe the relationship between the involvement of DONs and EDHNs in their marketing involvement. Involvement was divided into three categories: a rating 1.0-2.9 was considered low involvement, 3.0-4.9 wa? considered moderate involvement,_ and 5.0:7.0 was considered h1gh involvement~ It was·found that·nurses were involved in marketing overall at the moderate level·. There we~e significant differences at the 0.029 level in the involvement of DONs and EDHNs in marketing environment category. There were no significant differences between the involvement of the two groups in marketing system nor in marketing activities categories.

    • Small Nuclear RNA Sythesis in Isolated Mouse Erythroleukemia Cell Nuclei

      Braziel, Nina; N/A (1978-06)
      A set of small nuclear RNA.sp~cies (snRNA) in eukaryotic cells have been described. Their cellular function and method of formation is unknown. SnRNAs are found predominately in the nucleus and have been - shown to consist of 9-14 discrete species (1). An in vitro isolated nuclear system capable of synthesizing this class of RNA would greatly facilitate the study of l) the RNA polymerase(s) responsible for their. synthesis and pos$ible derivation from other classes of nuclear RNA, 2) transport from the nucleus and 3) post transcriptional modifications such as methylation and capping. Mouse erythroleukemia cell nuclei were capable of synthesizing RNA linearly for 70 minutes. A labeled ribonucleoside triphosphate was . ' incorporated into· RNA at a rate of 7 pmols/~gnuclear DNA/50 minutes. . " Maximum synthetic activity required the presence of high concentrations of all four ribonucleoside triphosphates (1 mM), a low incubation temperature (25°C), ~nd 5 x 107 nuclei/ml. The effect of a-amanitin on total RNA synthesis was examined. RNA polymerases A, B, and C were functioning in nuclei isolated from MEL cells in mid-log phase. The RNA synthesized .:!.!!_ vitro sedimented in sucrose gradients at approximately 4 to 20S. The synthesis of two species of rapid turn-over snRNA (C and A) was· detected, one with the same electrophoretic mobility as 5S rRNA and one with that of 4.5S pre-tRNA. Indications of the synthesis qf snRNA species D, E, arid F were observed as was the synth~sis ·of snRNA species· ~~, which unlike D, E; and F can be recovered from both cytoplasmic and nuclear cell fractions .
