New Media, New Structures: How Digital Journalists Frame Renewable Energy Stories
No full textHow do online media professionals educate the public about environmental impacts of energy issues? While past research suggests media utilize concise episodic frames to clearly convey the news, this study found that for environmental energy topics, communicators used thematic frames to more thoroughly articulate complex scientific energy issues for online audiences. Thus, journalistic framing of energy issues can highlight environmental impacts through more informative online science communication
Characterization of Phytic acid in Tempered Canned Red kidney beans (Phaseolus vulgaris) using Raman Spectroscopy
Get PDFRapid and non-invasive analytical method for quality control is a priority for the food industry, hence the objective of this study is to use Raman spectroscopy (RS) to identify phytic acid in RKB. Phytic Acid was extracted from treated ground dry RKB, while standard concentration of PA was prepared from a PA solution 50% w/w. Extracted samples and standard solutions were analyzed using the RS. The laser light beams focused on the PA samples generated molecular bond vibrations which resulted to inelastic scattering of photons in the light beam. The result showed that P-O-C, and P=O which are bonds identified with PA emitted light intensities at wavelength 858.13, and 1198.04 nm, respectively. Correlation (0.93) was established between results obtained for the standard RAMAN spectroscopy method and UV spectrophotometric method. Canned BL treatments showed increased concentration with blanched samples with lowest concentration (0.1175 g/mL) for P-O-C. Thus, the correlation established is indicative that the RS has potential applications in the food industry

Due to this concern, the most potential sunscreen effect on microemulsion extract from Melaleuca cajuputi essential oil stabilized using different nonionic surfactant TWEEN 20, TWEEN 80, SPAN 20 and SPAN 80 have been investigated. All microemulsions were formulated via triangle phase diagram, emulsification process, stability test, Scanning Electron Microscope (SEM) test and Ultraviolet-Visible (UV-Vis) spectroscopy test. For triangle phase diagram, the most stable formulation microemulsions were composed of nonionic surfactant TWEEN 20, TWEEN 80, SPAN 20 and SPAN 80, olive oil and water with region have been constructed using microscopic test. For emulsification process, the compatible formulation microemulsion was taken from all formulations involved the stability test. For SEM test, the size for each droplets of microemulsion for Formulation 1, Formulation 2, Formulation 3 and Formulation 4 were smaller than expected which is below than 5μm. However, only Formulation 2 was indicated in stable formulation and clearly seen compared to other formulations under SEM test. Result obtained for UV-Vis test was observed Formulation 1, Formulation 3, and Formulation 4 has absorbed only UV-C region with indicate value of increment. Meanwhile, Formulation 2 has absorbed UV-B region that prevent skin from cancer risk. Therefore, Formulation 2 shows good absorption and exhibit high potential to be further developed and use as sunscreen in cosmeceutical products
The Research on Establishment of “Clinical Practice Guide of Blood Specimen Collection, Preservation and Delivery for Clinical Nurseâ€: Protocol Description
Get PDFINTRODUCTION AND OBJECTIVE: The correctness of the blood test is closely related to the sample. According to the recent reported data, 80 percentage unsatisfactory results of the clinical test are due to the poor quality of sample, especially the blood sample. Clinical practice guide (CPG) is directly to instruct the clinical nursing practice. And the recommendations in the clinical practice guide are based on the best available study evidences. There is lack of CPG about blood sample specimen collection, preservation and delivery (BSCPD) in China. Additionally, related published clinical studies are accumulated in a great deal. Therefore, establishing a CPG is necessarily and practicable. The detailed objectives are: 1) to describe and analyze the research status of BSCPD in China; 2) to describe and analyze the practice status of BSCPD in China; 3) to systematic appraise the available evidences of BSCPD; 4) to establish the clinical practice guide of BSCPD; 5) to judge the clinical practice guide of BSCPD. METHODS: Objective 1): Bibliometric analysis is applied, the database include China National Knowledge Infrastructure Database (CNKI) and Sino-med and the research period is from the year of 2003 to 2013; Objective 2): Questionnaire survey for all the registered clinical nurses in a grade three hospital; objective 3): Systematic review according to Cochrane collaboration handbook 5.1.0 is applied which includes assessment of risk of bias, data extraction, data analysis; Objective 4) and 5): Using the appraising guidelines research and evaluation (AGREE) to evaluate of the draft of CPG of BSCPD. RESULTS: Bibliometric analysis started in 2013, and search strategies have been established. Questionnaire survey setting and depth interviewees have been identified and communicated. CONCLUSIONS: The CPG of BSCPD will serve as an important resource in instructing and modifying clinical nursing practice. Given this CPG of BSCPD will be a draft version, the applicability and suitability of it will need a further evaluated in the real clinical nursing world

“The Ultimate in Care†An exploration of the way clinical educators harness experiences of death and dying
Get PDFThis study looked at the lived experiences of clinical nurse educators who work with undergraduate nursing students in a hospital setting. It employed a phenomenological approach to focus on nurses’ personal experiences of death and dying. In particular this paper examined how nurses perceive the way the experiences influences the way that they instruct their students Informal interviews with four nurses were audio taped and transcribed. Rich descriptions of emotions which emerged are discussed in detail. Data were analysed using the Colaizzi method of analysis and common themes were identified. They included remaining professional, Humanizing stories and teaching different levels of undergraduates. These themes were evaluated in terms of their value of meaning for students and the possible implication for clinical care. The literature examined relevant to the study has previously identified the importance of nurses knowing the meaning of end of life care; caring and empathy; student nurses’ perception and the need for student belongingness. The study has added to the field by identifying the importance of nurses sharing personal experiences to enhance student learning in this already difficult area of nursing
Spirituality and Self-Reclamation: A Response to Nursing on the Margins of the Profession
Get PDFThis paper focuses on spirituality and religious faith as a significant resource in the lives of Black nurses in a Nova Scotia, Canada. It argues that as a valuable source of self-identity and meaning-making, spirituality merits serious consideration in nursing research. This treatment of the subject brings together current attention to the work-life experiences of minority nurses in Canada’s healthcare system and new interest in spirituality as inherent to nursing care. Validating the spiritual strength and sensitivity expressed by the Black nurses would both allow the nurses to be wholly themselves as nurses, and make that strength and sensitivity available to a healthcare system that has need of them. It might be possible to bring both minority group nurses and spirituality back from the margins of the nursing profession
Psychological Capital as Mediator between Adaptive Perfectionism and Academic Procrastination
Get PDFResearch on perfectionism and separately on procrastination is extensive and both are related in general to negative consequences. However, there has been little research on different forms of perfectionism (maladaptive vs adaptive) and the relationships with procrastination. One study (Seo, 2008) has suggested that self-efficacy mediates between adaptive perfectionism and procrastination in academic settings and leads to more productive outcomes. Identifying further such positive productive factors may prove useful in helping individuals deal with their perfectionism and-or their procrastination tendencies. Positive psychological capital (PsyCap) may be one such other mediator, as PsyCap involves not only self-efficacy but also resilience, hope and optimism—attributes that have been associated separately each in their own right with positive behaviour and not with normal academic procrastination Most studies of PsyCap have occurred in organisational settings and may also be considered to be important attributes in the academic setting. Psychological capital as a positive mediator between adaptive perfectionism and procrastination in an academic setting was therefore examined in the current study, with results supporting the mediation effect. The implication is that those students with perfectionistic attributes can be helped to control some of the negative outcomes (such as procrastination) by developing skills in psychological capital. How this might work is discussed. Further detailed studies are needed including replication and identification of other mediators
Silent Phase of Johne’s Disease in Experimentally Infected Goats – A Study on New and Established Diagnostic Approaches Using Specific and Non-Specific Parameters
Get PDFThe current gold standard diagnostic test for Johne’s disease (JD) is detecting Mycobacterium avium subsp. paratuberculosis (MAP) from fecal samples via culture and/or PCR. Other commercially available JD diagnostic tests focus on the detection of specific antibodies within the serum or milk of infected ruminants. These tests have a high specificity but low their sensitivity and usually fail to diagnose the disease until later stages of the disease. The ideal diagnostic test should detect infected animals already during the silent phase. Here, we evaluate the use of new and established approaches to define the silent phase of JD in experimentally infected goats. None of the established diagnostic tests or new approaches for the detection of humoral and cellular immune responses were positive during the first year of infection. Only the characterization of various subsets of peripheral blood leukocytes and the weight development gave some indication for the presence of a chronic, but silent, infection. Weight differences were present throughout the first year. In addition, some of the subsets of leukocytes (WC1+ ï§ï¤ T cells, MHC class II+ leukocytes, CD1+ leukocytes, CD14+ granulocytes, and CD14+/MHC class II+ granulocytes) demonstrated significant differences, but only at certain time points
