Difficulties Felt by Intensive Care Unit Nurses in Providing End-of-Life Care in Southeast Iran
Get PDFIntroduction: Critical care deaths represent most
hospital deaths. The difficulties felt by intensive care
unit (ICU) nurses providing end-of-life care may cause
nurses to experience negative attitudes toward caring
for dying patients. This study was conducted to examine
the difficulties felt by ICU nurses providing end-of-life
care in Southeast Iran. Method: The study used a
cross-sectional descriptive design and was conducted
in 3 hospitals supervised by Kerman Medical
University. Using DFINE (difficulties felt by ICU nurses
providing end-of-life care), difficulties felt by critical care
nurses providing end-of-life care were assessed.
Results: The results indicated that the difficulties that
were felt by critical care nurses were moderate
(2.64 T 0.65). Among the categories and items, the
most difficulties felt by critical care nurses belonged
to the category of ‘‘converting from curative care to
end-of-life care’’ (3.12 T 0.93) and the item ‘‘life-sustaining
treatment is often given excessively’’ (3.49 T 1.14).
Conclusions: The study suggests that health care
managers should organize systematic and dynamic
policies and procedures in dealing with end-of-life care to
assist ICU nurses
Prediction of Learning Styles Using Students’ Self-esteem
Get PDFBackground & Objective: Learning style is a distinctive, habitual behavior to gain knowledge,
skills, or feedback attained through study or experience. The key to engaging students in
learning the content is identifying their preferences and learning styles as well as identifying
factors influencing these variables. To reach this goal, predictive variables of learning styles
should be accurately identified in order to improve the learning environment. The aim of this
study was to determine the relationship between learning styles and self-esteem in students of
Kerman University of Medical Sciences, Iran.
Methods: This descriptive-analytical and cross-sectional study was carried out on 343 students
selected through quota sampling method. The data collection tools consisted of a demographic
information form, the Kolb Learning Style Inventory (LSI) version 2, and the Rosenberg SelfEsteem
Scale (RSES). Data were analyzed using chi-square test, Spearman’s correlation
coefficient, linear regression, and logistic regression.
Results: The mean (± SD) age of the participants was 21.41 (± 2.96), and 44.3% of students
used absorbent learning style. In addition, 60.9% of students had poor self-esteem. No
statistically significant association was observed between students’ learning styles and levels of
confidence. In addition, the results showed that only gender was a prognostic factor in
determining learning styles.
Conclusion: The results of this study showed that the students’ self-esteem and learning styles
were not correlated; thus, teachers can disregard these factors in their assessment of students'
learning styles.

Guided imagery effects on chemotherapy induced nausea and vomiting in Iranian breast cancer patients
Get PDFBackground: The objective of this study was to examine the effect of guided imagery on chemotherapy
induced nausea and vomiting in breast cancer patients.
Design: This was a quasi-experimental study in which a group of sample was evaluated pre and post
intervention. A convenience sample of 55 eligible breast cancer patients enrolled to participate in this
study after giving informed consent. They completed the Morrow Assessment of Nausea and Vomiting,
before and after the intervention. The intervention consisted of listening to the two guided imagery
tracks.
Findings: After the intervention, patients at the third session of chemotherapy had significantly lower
mean scores in the frequency and severity of nausea and vomiting pre and post chemotherapy (p < 0.05).
Conclusions: Guided imagery, as an inexpensive and noninvasive method, is particularly appealing option
to alleviate chemotherapy induced nausea and vomiting. It can be used in addition to pharmacological
strategies and can be implemented by patients independently with sufficient training. Therefore,
this therapy will considerably improve severity and frequency of chemotherapy induced nausea and
vomiting
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
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
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
Missed care in neonatal intensive care unit: effect of electronic reminders
No full textAbstract Background Missed nursing care is a newly defined concept and refers to any aspect of required patient care that is omitted or delayed. This study aimed to determine the effectiveness of electronic reminders on missed care in NICU. Method This is a two groups (before and after) quasi experimental study. A random sampling technique was employed to collect a sample of 70 nurses among two NICUs in an educational hospital in the south east of Iran. Miss care questionnaire was used to determine Missed care before, immediate, and one month after the intervention. The study intervention includes sending electronic reminders regarding nursing care of NICU hospitalized neonate. Data were analysed using SPSS20 software, descriptive (frequency, percentage, mean, and standard deviation), and analytical statistics. The level of significance was considered as 0.05. Results The results showed that the mean score of missed care was decreased after intervention in the intervention group (6.74 ± 8.47) rather than the control group (18.57 ± 14.59) (P = 0.001). The highest and the lowest mean score of missed care before and after the intervention was in general care and oxygen therapy domains in both groups. The second time intervention was one month after did not show any significant differences in the two groups. But decreasing in missed care was shown in both groups. Discussion Using informational technologies like WhatsApp is an easy, low cost and available method which could help nurses decrease missed nursing care. More studies with a longer duration could probably have a greater impact on reducing missed care
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
