Salienza, tonalità e memoria musicale esplicita nell’invecchiamento.
No full textPer approfondire la relazione tra caratteristiche dello stimolo musicale e memoria esplicita nell’invecchiamento,un gruppo di soggetti anziani esperti e non esperti, sono stati sottoposti ad un compito di codifica non incidentale e riconoscimento di 24 brani musicali inediti che variavano per salienza e tonalità. Dopo aver ascoltato 24 brani musicali, veniva presentata una lista composta da 24 stimoli vecchi e 24 stimoli nuovi.
Rispetto ad ogni brano musicale si richiedeva al soggetto di decidere se era presente nella lista precedente (risposte R), se evocava un senso di familiarità (risposte K) o se non era mai stato ascoltato (risposte X). I risultati sono discussi e interpretati analizzando la relazione tra tipo di stimolo e tipo di risposta nei due gruppi di soggetti poiché studi precedenti hanno dimostrato che, in soggetti non esperti, la salienza è mediata dal sistema di memoria episodico mentre la tonalità dal sistema di memoria semantico
Episodic and semantic musical memory in elderly people
No full textThe present study evaluates the role of salience and tonality of music on recognition memory in elderly non-musicians. A recognition memory task for unknown musical stimuli belonging to different categories [tonal/salient, tonal/non-salient, non-tonal/salient and non-tonal/non-salient] was administered to 42 subjects (mean age 75 ± 7.5). Correct and incorrect ‘remember’ (R) and ‘know’ (K) responses, respectively related to episodic and semantic memory according to Tulving’s model, and ‘no’ recognition responses (X) were analyzed. A comparison with a population of young subjects was performed too. Results show that saliency is a significant factor for correct R (episodic memory), whereas tonality is a significant factor for correct K (semantic memory). The number of times the ‘study list’ was listened to does not seem to substantially affect memory recognition. Elderly adults’ performances show similar trends as young subjects’ for correct R, K, and X. Viceversa, elderly subjects gave significantly more incorrect answers for R and X, while no difference between the two groups was found for incorrect answers related to semantic memory (X), confirming the acculturation value of tonality
Il funzionamento individuale autopercepito in anziani sani e con deterioramento cognitivo tramite somministrazione dell'WHODAS II
No full textDopo una recente validazione italiana dell’WHODAS II (Federici et al., 2009a; 2009b) si intende valutare il comportamento dello strumento su un campione di 300 soggetti (100 anziani con deterioramento cognitivo, 100 anziani sani e 100 caregiver) in relazione a tre obiettivi: (i) misurare l’affidabilità dell’WHODAS II all’aumentare della gravità del declino cognitivo; (ii) stabilire se le risposte ottenute dai caregiver risultino attendibili e predittive delle diagnosi cliniche dei pazienti; (iii) comprendere la relazione che intercorre tra risposte all’WHODAS II da parte dei tre gruppi considerati e il livello di stress percepito dai caregiver misurato con il “Brief Symptom Inventory” e il “Caregiver Burden Inventory”. Il presente studio esporrà i dati relativi ad un primo campione pilota di 60 soggetti (20 anziani con deterioramento cognitivo, 20 anziani sani e 20 caregiver).

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
