Controllo e governo sostenibile della «crescita aziendale»: il caso Colmic Spa
No full textIl contributo si focalizza sui processi di crescita aziendale, mettendo non solo in evidenza le sottostanti motivazioni, ma anche alcune delle strategie atte a realizzare tali processi con successo ed in modo duraturo o “sostenibile”. L’articolo evidenzia inoltre il ruolo che può essere svolto da un efficace sistema di controllo di gestione, sia nella fase di progettazione degli interventi volti ad innescare la crescita, sia tramite un controllo ed un reporting in itinere ed ex-post tali da fornire un valido supporto informativo ai decision-makers. Nello specifico, il contributo analizza il caso della Colmic SpA, illustrando il percorso di crescita intrapreso, discutendone le politiche innovative implementate ed evidenziando il ruolo svolto dal sistema di controllo adottato nell’efficiente gestione delle risorse strategiche a disposizione dell’azienda

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

No full textBasis for the implementation of an EEG-based single-trial binary brain computer interface through the disgust produced by remembering unpleasant odors
No full textIn order to implement an EEG-based brain computer interface (BCI), a very large number of strategies
(ranging from sensory
–
motor, p300, auditory based, visually based) can be used. However, no technique
exists which is based on the olfactory stimulation or, better, based on the imagination of olfactory
stimuli.
The present paper describes an innovative paradigm, that is the voluntary brain activation with the
disgust produced by remembering unpleasant odors, and a simple and robust classi
fi
cation method on
which a single trial binary BCI can be implemented. In order to classify the signal, mainly the channels
P4, C4, T8 and P8 have been used, by spanning the frequency band between 32 and 42 Hz, that is a
subset of the gamma band external to the bands usually occupied by other tasks (the interval between
1 and 30 Hz), and the alpha band between 8 and 12 Hz.
Right hemisphere of the brain and gamma band of frequencies are particularly sensitive when
experiencing negative emotions, such as the disgust produced by smelling or remembering unpleasant
odors, while the alpha band is usually modi
fi
ed with concentration. This constitutes an advantage for the
proposed classi
fi
cation technique because it is made intrinsically easy by the localization into particular
positions and frequencies: different features are mostly based on different frequency bands.
The choice of disgust produced by remembering unpleasant odors is twofold: smelling is an ancestral
sensation which is so strong that its EEG signal is produced also in persons affected by hyposmia when
they imagine an olfactory situation; it can be used without external stimulation, that is the user can
decide freely when and if activate it.
The proposed method and the experimental setup are described and a series of experimental
measurements are presented and discussed. The accuracy of the proposed method is also evaluated and
the reached levels are about 90%. The proposed system can be a useful communication alternative for
disabled people that cannot use other BCI paradigms
3D Modelling to Support Dental Surgery
No full textIn a previous work, we developed a general purpose framework to support the three-dimensional reconstruction,
rendering and processing of biomedical images, 3D Bio-IPF. In this paper we present a structured component of
3D Bio-IPF, the plug-in Implant, to model customised dental implants on a three-dimensional representation
of the oral cavity derived from diagnostic images. The proposed tool was tested on different cases and a result
is reported. It has been proven it is very effective for dental surgery planning, implant design and positioning.
Moreover, if integrated with a position indicator system and a numerically positionable drilling machine, it
could be employed for semi-automatic surgery
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
