Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
La ricerca sull’intonazione del sardo: stato attuale e prospettive future.
No full textQuest’articolo ha due obiettivi principali: offrire una panoramica sulle ricerche attuali nell’ambito dell’intonazione del sardo e analizzare alcuni possibili benefici applicativi della ricerca sulla prosodia. Tra gli aspetti più caratteristici dell’intonazione del sardo segnaliamo il mancato utilizzo sia del tono alto per marcare continuazione che dei toni ascendenti nelle frasi interrogative, associato all’uso abbondante di toni extra alti (nelle frasi interrogative) e di prominenze iniziali (nelle dichiarative di focus contrastivo e nei vocativi). È inoltre interessante ricordare che spesso in sardo l’accento nucleare non è realizzato sull’elemento più a destra, ma su quello più a sinistra. Tra le varietà considerate, il logudorese e il campidanese, non sono state riscontrate chiare differenze dialettali di intonazione, differenze invece riscontrabili nel maggior uso per il logudorese della particella interrogativa a, e nell’uso relativamente più raro in campidanese del troncamento vocativo. Per quanto riguarda la ricerca linguistica teorica e applicata siamo in grado di immaginare un futuro pieno di possibili applicazioni pratiche per tutte le lingue, sardo incluso. Il nostro auspicio è che la raccolta di dati su quest’ultima lingua e la loro applicazione in ambiti come la didattica e le nuove tecnologie possano favorirne un uso che tenda sempre più alla piena normalità
Interazione tra la disfunzione del cammino e la sindrome ostruttiva profonda di gamba
No full textIl principale meccanismo del flusso venoso, in posizione ortostatica, è costituito dalla pompa venosa muscolare. L'origine dell'azione di pompa nasce a livello dei muscoli della pianta del piede e prosegue con al contrazione dei muscoli della gamba attraverso la "spremitura" delle vene inter e intramuscolari
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
HEALTH-RELATED QUALITY OF LIFE AS A SURVIVAL PREDICTOR FOR PATIENTS WITH ORAL CANCER: IS QUALITY OF LIFE ASSOCIATED WITH LONG-TERM OVERALL SURVIVAL?
No full textOBJECTIVE:
The aim of the present prospective study was to obtain further insight into health-related quality of life (HR-QoL) as a predictor of survival in a selected cohort of patients with oral cancer.
STUDY DESIGN:
A total of 124 patients were treated with surgery or combined therapy. All of the recruited patients completed the European Organization for Research and Treatment of Cancer questionnaires QLQC30 and H&N35 on 4 occasions. Overall survival was assessed. Univariate and multivariate Cox proportional hazards regression models were conducted.
RESULTS:
High baseline HR-QoL score and high pain symptom score were significantly associated with a better survival (HR 0.86 and 0.92 respectively). Swallowing (HR 0.94), and speech (HR 0.92) high baseline scores were also significantly associated with a better survival in the adjusted analyses.
CONCLUSIONS:
Patients who reported a better HR-QoL at tumor diagnosis had a better survival than patients with a lower HR-QoL baseline score
COMPARAZIONE FRA TRE DIFFERENTI DISPOSITIVI PER LA MISURAZIONE DELLA TEMPERATURA CORPOREA IN ETA’ PEDIATRICA: UNO STUDIO OSSERVAZIONALE
No full textThe inner parsecs of our Galaxy: Star formation and its environment
No full textWe aim to investigate the formation of young stars in the inner parsecs of the Milky Way by means of adaptive mesh refinement (AMR) hydrodynamical simulations. Observations show the presence of young massive stars and possible on-going star formation in the vicinity of the central supermassive black hole (SMBH).Though star formation is expected to be inhibited by the strong tidal field of the SMBH, several studies show that stars could be born out of molecular gas reaching the center from tens of parsecs distance. Compared to previous studies, we will study star formation in the innermost parsecs through treatment of heating/cooling processes, non-equilibrium chemistry and radiation effects
