Effect of a triage course on quality of rating triage codes in a group of university nursing students:a before-after observational study.
Full text linkBACKGROUND: Most current triage tools have been tested among hospital nurses groups but
there are not similar studies in university setting. In this study we analyzed if a course on a new fourlevel
triage model, triage emergency method (TEM), could improve the quality of rating in a group of
nursing students.
METHODS: This observational study was conducted with paper scenarios at the University of
Parma, Italy. Fifty students were assigned a triage level to 105 paper scenarios before and after a
course on triage and TEM. We used weighted kappa statistics to measure the inter-rater reliability of
TEM and assessed its validity by comparing the students' predictions with the triage code rating of a
reference standard (a panel of fi ve experts in the new triage method).
RESULTS: Inter-rater reliability was K=0.42 (95%CI: 0.37–0.46) before the course on TEM, and
K=0.61 (95%CI: 0.56–0.67) after. The accuracy of students' triage rating for the reference standard
triage code was good: 81% (95%CI: 71–90). After the TEM course, the proportion of cases assigned
to each acuity triage level was similar for the student group and the panel of experts.
CONCLUSION: Among the group of nursing students, a brief course on triage and on a new inhospital
triage method seems to improve the quality of rating codes. The new triage method shows
good inter-rater reliability for rating triage acuity and good accuracy in predicting the triage code
rating of the reference standard
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Is it possible to predict the clinical course of gallstone disease? Usefulness of gallbladder motility evaluation in a clinical setting
No full textOBJECTIVE:
A knowledge of the predictive factors of the development and persistence of symptoms in gallstone patients (GS) plays a key role in clinical decision making. The aim of this study was to evaluate the presence of predictive factors for biliary pain development in GS, stressing the role of gallbladder motility.
METHODS:
A total of 153 (104 women, 49 men) consecutive GS were enrolled. Gallbladder motility (%Emptying [%E], residual volume [RV]) was evaluated by ultrasonography and biliary symptoms were evaluated using a specific questionnaire in all GS at baseline and after 4 yr of follow-up.
RESULTS:
At enrolment, 61 GS reported recent (GSr) and 31 GS remote (GSo) (>2 yr before) episodes of biliary pain, and 61 were asymptomatic (GSa). At baseline, GSr showed a greater %E and a smaller RV than both GSo and GSa (p < 0.001). After follow-up, biliary pain developed more frequently in GSr (33.3%) than in GSo (16%) and GSa (15%) (p= 0.04). The search for predictive factors of biliary pain development (by univariate and multivariate analyses) revealed a high %E, a small RV, and a history of biliary pain as risk factors.
CONCLUSIONS:
Efficient gallbladder motility is present in symptomatic GS and it represents a risk factor for biliary pain development while sluggish motility seems to play a protective role. Thus, gallbladder motility evaluation is a useful diagnostic tool in clinical decision making for GS; in symptomatic GS, a progressive reduction of gallbladder motility could suggest a "wait and see" management policy instead of an immediate surgical approac
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
