Rischio da movimenti ripetitivi dell' arto superiore:aspetti in cassieri di supermercati
No full textAllo scopo di investigare sul rischio da movimenti ripetitivi degli arti superiori in cassieri di supermercati, sono stati arruolati 250 cassieri del centro Italia e per la stima del rischio sono state utilizzate le procedure aggiornate della checklist OCRA L' elaborazione statistica, effettuata utilizzando il software SPSS 20.0, ha in sintesi evidenziato predominanza dell’arto destro e prevalenza (54,4%) di rischio medio (14,1-22,5). I punteggi della checklist sono risultati associati (p<0,001) e correlati positivamente all’età (p<0,05) e alle variabili della checklist (p<0,001) mentre la correlazione (p<0,001) con le pause è risultata ovviamente negativa. La “forza” è emersa come variabile maggiormente correlata ai punteggi della checklist (r=0,889) e non si è evidenziata alcuna influenza dell’età sulle correlazioni investigate. I punteggi emersi dalle procedure aggiornate e dalla checklist tradizionale, pur risultando correlati (p<0,001), appaiono privi di concordanza (K di Cohen=0,000).250 supermarket cashiers were enrolled in central Italy, using the checklist OCRA updated to assess the risk from repetitive movements of the upper limb. The data were submitted to statistical analysis using the SPSS 20.0 software. After descriptive analysis, was evaluated the association or independence between the checklist scores and the other variables (with t test and Chi-Square test) and any correlations (with rho Spearman coefficient), evaluating the influence of age by calculating the partial correlations and comparing the results of updated and traditional checklist by calculating the concordance (Cohen's K). The results show right limb predominance and prevalence (54.4%) of medium risk (14.1 -22.5). The checklist scores are associated (p < 0.001) and positively related to age (p < 0.05) and to checklist variables (p < 0.001), while the correlation (p < 0.001) with the pauses is obviously negative. The "force" is the variable most correlated to checklist scores (
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
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
MANAGEMENT OF BILIOPANCREATIC DIVERSION COMPLICATIONS
No full textBackground: In our Centre of bariatric surgery, active since 1974, we have never utilized the biliopancreatic diversion (BPD)for its incomplete reversibility and its surgical aggressiveness but, from the beginning of 80’s, we have hospitalized for severe
complications 20 patients who underwent this procedure in different
centres and in different times. Here, we report our experience
of management of BPD complications, particularly with reference to the last 7 patients treated in the last 3 years.All the
patients were operated on the same type of BPD.
Methods: The patients are all females, mean age 42.5 years (25 – 47); mean weight pre-BPD 92.5 Kg (82 – 114); mean
weight at the moment of hospitalization 65 Kg (55-89); mean BMI pre-BPD 35,6 (34 – 45); mean BMI at the moment of the
hospitalization 25,3 (20 – 36);mean follow-up 9,5 years (2 - 17).We observed these complications: insufficient weight loss (1
patient : from 91 to 89 Kg); excessive weight loss for persistent
malabsorption ( 3 pts); severe osteomalacia for alteration of calcium
and vitamin D metabolism (2 patients), 1 with spontaneous pertrocanteric fractures; severe hypoproteinemia ( 7 pts ); iron deficiency anaemia ( 6 pts). One patient had numerous
haematic transfusions; severe and late dumping syndrome (1 pt); halitosis (3 pts); persistent diarrhea more than 5 evacuations/day (1 pt); liver failure (1 pt). Six patients were treated with
hyperproteic and hypercaloric parenteral nutrition (PN), and
with polyelectrolytes and polyvitaminics endovenous infusion for
more than 60 days, in the hospital and/or at home, till to gain an
acceptable metabolic balance.We have converted 3 patients to adjustable gastric banding according to Kuzmak and 2 patients had reversal; the others are still under medical care.
Results: Hyperproteic and hypercaloric parental and oral nutrition obtained in all patients a good metabolic balance.
Three patients didn’t achieve a stable metabolic balance at the
end of PN so that it was necessary a reversal of BPD or conversion
to adjustable gastric banding in accordance with the patient, the internist and the psychologist. One patient had reversal for psychological indication.Post-operative course was
uneventfull for 2 patients; 1 patient had an acute hemorrhagic
gastritis in the first post-operative day, treated with medical care.
One patient had a revision for intestinal occlusion. The patient
who had an insufficient weight loss after BPD, had a good result
after adjustable gastric banding (from 89 to 70 Kg, BMI 25).The
other patients had an increase of 20 Kg one year after reversal.
Conclusion: Our experience permits to underline that: 1) BPD can be better used in the morbidly obese patients with BMI > 40;
2) the choise of the patients must be careful, particulary by psychological
point of view; 3) BPD requires a continous, constant and rigorous follow-up to prevent or to opportunely treat the metabolic complications such as all malabsorption bariatric procedures.
These all complications can be successfully traited medically or surgically; 4) BPD doesn’t permit the complete reversibility because of gastrectomy but only a partial functional one; 5) the metabolic complications and the failures of BPD can be treated by conversion into adjustable gastric banding
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
