The Colline Teramane wine district. An analysis of sustainability and eco-efficiency of the producing system.
No full textThe study perform an analysis of sustainability and eco-efficiency of the Montepulciano d’Abruzzo producing companies belonging to the Colline Teramane wine district.
The objectives of the study are: the analysis of the environmental impacts of the whole production process of the companies belonging to the Consortium “Colline Teramane”, applying the LCA methodology and comparing the two main products (DOC and DOCG wines) and the conventional and organic production methods; and the eco-efficiency analysis to make a comparison among companies and assumptions about good practices to be implemented
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
Children with primary complex motor stereotypies show impaired reactive but not proactive inhibition
No full textTypically, the inability to control urges tends to be ascribed to a lack of inhibitory control. Primary complex motor stereotypes (p-CMS), occurring in children with an otherwise typical development, represent a remarkable example of involuntary, complex, repetitive and apparently purposeless movements. However, it has never been tested whether the core of the pathophysiology of p-CMS lies in a deficit of inhibitory control. To fill this gap, we assessed whether children with p-CMS exhibit an impairment of one or both types of inhibition, i.e., reactive inhibition (the ability of subjects to react to a stop-signal) and/or proactive inhibition (the ability of subjects to shape their response strategies according to the context in which subjects are embedded). We compared inhibitory control of 20 drugnaı ̈ve patients with p-CMS (mean age ±SD: 7.4 ± 1.1) with that of 20 age- and gendermatched typically developing children (7.5 ± 1.2) via a reaching version of the stop-signal task. We found that while reactive inhibition is significantly impaired, proactive control in children with p-CMS is similar to that of the control group. The deficit in reactive control might explain why patients are unable to inhibit involuntary movements when triggered by states of mind such as stress, fatigue, boredom or excitement. Nevertheless, the absence of a deficit in proactive control suggests that patients are aware of the environmental context and thus they quickly stop the stereotypic movements when their attention is diverted. All in all, our findings might explain two key features of the p-CMS phenotype
Rage attacks in Tourette syndrome and chronic tic disorder: a systematic review
No full textTourette syndrome (TS) and Chronic motor/vocal Tic Disorder (CTD) are neurodevelopmental conditions defined by the occurrence of multiple tics. Besides the well-known association with attention deficit/hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD), rage attacks (RA) represent common and detrimental symptoms for patients. In order to explore prevalence of RA in tic disorders, relation to tic severity/comorbidities and available treatments, we performed a systematic literature review based on PRISMA Guidelines. 32 studies published between January 2008 - December 2019 were deemed suitable for the analysis and provided a prevalence of 20-67%. Most findings showed a direct correlation with tic severity and a significant impact on psychosocial functioning. Although apparently related to comorbid ADHD, RA also frequently occur as independent manifestations. Association with other comorbidities, such as OCD, impulse control and mood disorders has also been reported, not yet fully established. Behavioral interventions appear to be effective, whereas there is limited evidence concerning the efficacy of medication. In TS/CTD, RA may be regarded as a major comorbidity that requires clinical investigation in order to develop personalized treatments
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
