No full textValutazione degli effetti della l-admantil-ammina cloridrato e della L-DOPA in associazioine ad inibitore della decarbossilari periferica nei confronti della sintomatologia di 5 schizofrenici catatonici. Effetti favorevoli sono osservati sullo stupore catatonico e catalessia, nessun vantaggio su negativismo, automatismi stereotipi
Modificazioni psicologiche in parkinsoniani in corso di trattamenti farmacologici con L-DOPA, amantadina e L-DOPA+IDC
No full textSono state valutate le funzioni cognitive e le modificazioni psicopatologiche in pazienti affetti da malattia di Parkinson: 20 pazienti sono stati trattati con L-DOPA a dosi comprese fra 3-4 gr; 15 pazienti sonos stati tratti con AMANTADINA e.v. alla dose di 300 mg/die; 10 pazienti con L-DOPA+IDC per os alla dose di 800 mg al dì. E' stata utilizzata una batteria di tests neuropsicologici per le funzioni cognitive e di tipo proiettivo. Le terapie a breve e medio termine non sembrano aver influenzato significativamente le funzioni cognitive e/o gli aspetti psicologici dei pazienti, tuttavia è stata evidenziata un'azione reintegrativa riavvicinando alla norma le capacità percettivo-motorie e lo schema dell'immagine corporea e, specie la L-DOPA, tende ad attenuare la sintomatologia depressiva
DANTROLENE SODIUM: STIMULATORY AD DEPRESSANT EFFECTS ON THE CONTRACTILITY OF GUINEA-PIG UTERUS IN VITRO.
No full textThe effects of dantrolene sodium on the spontaneous and oxytocin-induced contractions of guinea-pig uterus were studied in vitro. Dantrolene reversibly increased the spontaneous contraction frequency of guinea-pig uterus. The effect was not dose-related and was not antagonized by atropine, methysergide or indomethacin. Dantrolene dose dependently and reversibly reduced the contractile responses of guinea-pig uterus to oxytocin. The varying effects of dantrolene on the uterus probably involve inhibition of calcium movement at more than one site of the muscl
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
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
