Nurse's Opinions on School-Hospital Cooperation: Scale Development Study
No full textBackground and Purpose: This study aims to develop a valid and reliable measurement tool that can evaluate the views of clinical nurses on school-hospital cooperation and the scale of nurses. Methods: Within the scope of validity analyses for the development of the scale, content validity index, construct validity, and known group validity were used. Standard error, Cronbach's alpha, item-total score correlation, and scale response bias methods were used within the scope of reliability analyses. Results: In the final version of the developed scale, the Kaiser-Meyer-Olkin value was 0.90, and Bartlett's test result was chi(2): 2819.610, p < 0.001. It was determined that the total variance of the scale was 45.33%, and the Cronbach's alpha was 0.857. In the scale response bias analysis, the Hotelling T-2 value was 3585.645. Conclusions: It was found that the Nurses' Views of School-Hospital Cooperation Scale is a valid and reliable measurement tool
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Comparison of the Effectiveness of a Virtual Simulator With a Plastic Arm Model in Teaching Intravenous Catheter Insertion Skills
No full textThe objective of this study was to compare the effectiveness of a virtual intravenous simulator with a plastic arm model in teaching intravenous catheter insertion skills to nursing students. We used a randomized controlled quasi-experimental trial design and recruited 65 students who were assigned to the experimental (n = 33) and control (n = 32) groups using the simple random sampling method. The experimental group received intravenous catheterization skills training on the virtual intravenous simulator, and the control group received the same training on a plastic model of a human arm. Data were collected using the personal information form, intravenous catheterization knowledge assessment form, Intravenous Catheterization Skill Test, Self-Confidence and Satisfaction Scale, and Fear Symptoms Scale. In the study, the mean scores in the control group were 20.44 for psychomotor skills, 15.62 for clinical psychomotor skills, 31.78 for self-confidence, and 21.77 for satisfaction. The mean scores in the experimental group were 45.18 for psychomotor skills, 16.28 for clinical psychomotor skills, 34.18 for self-confidence, and 43.89 for satisfaction. The results indicated that psychomotor skills and satisfaction scores were higher in the experimental group, while the clinical psychomotor skills and self-confidence scores were similar in both groups. More students in the control group reported experiencing symptoms such as cold and sweaty hands, significant restlessness, and tense muscles than those in the experimental group.Ege University Scientific Research Projects CommitteeEge University [2014.HYO.002]This research has been supported by Ege University Scientific Research Projects Committee (no. 2014.HYO.002)
The effect of the use of ultrasound in the success of peripheral venous catheterisation
No full textThe aim of this study was to investigate the effect of ultrasound-guided peripheral venous catheterisation in patients where difficulty was experienced in peripheral venous catheterisation. The study was conducted in the emergency department at a university hospital in Izmir Turkey. After obtaining institutional review board approval and written informed consent, 60 patients with a history or suspicion of difficult cannulation were enrolled with 30 patients in traditional and 30 in ultrasound group. In the ultrasound group, peripheral intravenous catheterisation was performed using a portable ultrasound device with 13.5 MHz ultrasound probe and 20 gauge intravenous catheter. The success rate of peripheral venous catheterisation was 30% in the control group and 70% in the treatment group. The success rate was significantly higher among the treatment group. The mean intensity of felt pain was 6.00 +/- 1.98 in the control group and 4.77 +/- 1.74 in the treatment group. The mean intensity of felt pain was significantly lower in the treatment group. The state of chronic disease affected the success rate in patients in the treatment group. (C) 2014 Elsevier Ltd. All rights reserved
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Comparison of the effectiveness of the virtual simulator and video-assisted teaching on intravenous catheter insertion skills and self-confidence: A quasi-experimental study
No full textBackground: With the advancement of technology, methods such as clinical scenarios, role playing, video demonstration and simulation are now used to develop psychomotor skills in nursing education. Virtual reality and video-assisted teaching are useful technologies for the development of skills and self-confidence. in the literature, there is a lack of studies comparing the effects of the two methods. Objectives: the aim of study is to compare the effect of the virtual simulator and video assisted teaching on the level of intravenous catheterization skills and self-confidence of nursing students. Thus, students are enabled to develop skills and work efficiently without the need for an instructor. Methods: This study was a randomized controlled quasi-experimental study. A total of 60 students was included in the study (30 in the virtual simulator group and 30 in the video group). in the virtual simulator group, each student performed an intravenous catheter insertion in the virtual intravenous simulator. in the video group, each student watched a training video on the peripheral intravenous catheterization skill in a classroom setting. Each of the students' level of intravenous catheterization knowledge, psychomotor skill and self-confidence score was evaluated. Results: Post-test knowledge scores was higher than pretest knowledge scores for both groups. There were no significant difference between the groups in terms of post-test scores. Students' scores of psychomotor skills were found to be higher in the virtual simulator group and self-confidence scores were similar in both groups. Conclusion: Teaching with the virtual simulator contributed to the students' skills more than the method used in the video training. Both methods are effective in the development of knowledge and self-confidence related to intravenous catheterization
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
