No full textIn the present study, based on injections of retro- or retro-anterograde tracers at the cortical level, we analyzed the amygdalar connections of the caudal ventrolateral prefrontal areas 45A and 45B of the macaque and compared them with those of the adjacent areas 8/FEF, 8r, 46v, and 12r. The results showed that areas 45A and 45B display reciprocal amygdalar connections, which appear to be considerably richer than those of their neighboring areas. Specifically, these two areas are a target of differentially weighted projections originating predominantly from the magnocellular and the intermediate subdivisions of the basal nucleus and are a source of projections mostly directed to the magnocellular subdivision of the basal nucleus and the dorsal part of the lateral nucleus. The present data, together with previous data on the thalamic connectivity of areas 45A and 45B (Contini et al. Eur J Neurosci 32:1337-53, 2010), suggest that direct and indirect-trans-thalamic-amygdalar connectivity is a characterizing connectional feature of these two areas. Specifically, the amygdalar connections of area 45A, for which a role in communication behavior has been proposed, could convey information on the emotional significance of communicative signals to this area, where it could play a crucial role in guiding appropriate social interactions. Furthermore, the amygdalar connections of area 45B, possibly involved in higher-order aspects of visual guidance of gaze, could convey information related to the relevance of visual stimuli, which could contribute to a representation of priority maps in this VLPF area
La rappresentazione del Capitale Intellettuale nelle Aziende Sanitarie
No full textThe document aims at describing the development and results of the Project “Intellectual capital”, coordinated by the Regional Healthcare Agency of Emilia-Romagna in collaboration with the University of Ferrara in the 2002-2004 period.
Intellectual capital is intended as a whole of knowledge possessed by all the people working in an enterprise, of the organizational strategies adopted and of the relationships of the enterprise with external subjects. These are all intangible elements, that are not quantifiable according to parameters of traditional financial and managerial accounting reports; they are therefore difficult to measure, count, economically evaluate. However, considering their importance, they have been described in particular as far as their impact on the healthcare organization is concerned.
Five healthcare organizations of Emilia-Romagna participated in the project:
three Local Health Trusts (Piacenza, Parma, Rimini);
a University Hospital Trust (Ferrara);
a Research Hospital (Rizzoli Orthopaedic Institutes in Bologna).
The document is divided in four Chapters, dealing with:
theoretical framework of reference, to clarify the concept of intellectual capital and its close connection with knowledge and intangible resources. Some hints on literature on the topic and a deeper analysis of the theoretical approach (the so called three ways) are also presented;
methodology adopted to develop the project in the participating Local Health Trusts: after the analysis on available literature and the identification of the reference framework, the workgroup has chosen the determinants of intellectual capital, its elements and the best indicators to represent it. The model was first experimented at the University Hospital Trust of Ferrara and was then spread to the other Health Trusts;
analysis model: different elements were considered to define a report scheme to represent intellectual capital in Health Trusts; the model identified is that usually adopted in economic-managerial literature and is divided in:
relational capital: the relationships of the enterprise with external subjects (patients, other healthcare organizations, Local governments, Region, Universities, other public and private research institutions, unions, providers, funders, citizens’ and voluntary organizations), that can favour the development of positive advantages, for example in terms of reputation;
individual capital: all the elements that can represent the level of education, knowledge, competence and career of human resources working in a Health Trust (doctors, nurses, technicians, administrative personnel, etc.);
internal capital: aspects connected with the internal management and organization of the enterprise, for example management, administrative processes, research and development, consulting and training activities delivered, technologies;
first results of the experimentation: comment and critical interpretation of the results through the cross-reading of the five reports. The aim is to analyse data and information collected on the three macro-themes (relational, individual and inte
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
