L’Offerta formativa dei Soci. Lo scenario della Formazione Manageriale in Italia (IX ed.)
No full textLa nona edizione del rapporto ASFOR sull’attività dei Soci
s’inserisce in un contesto socio-economico di persistente incertezza;
i segnali di ripresa di inizio anno hanno lasciato il posto
a rinnovati timori di una seconda recessione a causa della
crisi del debito sovrano in Europa.
I governi che nella crisi del 2008-2009 avevano reagito con
misure anticicliche per far fronte al calo della domanda privata, scontano sempre di più i dubbi dei mercati sull’effettiva sostenibilità
dei propri bilanci e i timori di default di alcuni paesi
e la fragilità delle istituzioni creditizie sembrano gettare nuove
ombre sulla ripresa economica.
In questo scenario il rapporto ASFOR, analizzando come i
Soci ASFOR abbiano affrontato un periodo difficile e quali risultati
abbiano conseguito nel 2010, ha voluto anche verificare
come essi siano preparati ad affrontare l’anno che si va chiudendo
e che cosa ci si possa aspettare dal prossimo.
Rispetto all’edizione precedente, il Rapporto 2011 integra anche
l’attività dei Soci rivolta alle Pubbliche Amministrazioni e
intende dare maggiore risalto alle specificità delle Corporate
University (CU) associate ASFOR. Il questionario è stato rivisto
in alcune sue parti per garantire una migliore confrontabilità
con i risultati dell’indagine sulla domanda di formazione
L’offerta formativa degli Associati ASFOR: Lo scenario della Formazione Manageriale in Italia
No full textIl rapporto ASFOR sulla formazione manageriale in Italia
giunge alla sua settima edizione confermandosi come un momento
di riflessione annuale dell’offerta formativa degli associati,
siano essi Scuole di Management, Corporate University
o Consorzi pubblici o privati dedicati alla formazione manageriale
in Italia.
L’indagine del 2009, pur mantenendo un nucleo di domande
costante rispetto agli anni passati, non poteva trascurare un focus
sugli effetti della crisi sull’attività degli associati. Sotto
questo aspetto il rapporto, realizzato nella prima parte dell’anno, può essere un’occasione utile a tutti per cominciare a confrontare
le previsioni iniziali con l’evoluzione effettiva dell’attività
formativa
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
Recycling of the Sesia-Lanzo Zone (Italian Western Alps) continental lithosphere during the Alpine subduction
No full textVariations 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
The role of mantle hydration in continental crust recycling in the wedge region
No full textIn orogenic belts high pressure–low temperature (HP–LT) metamorphism can widely affect units derived from both the oceanic and the continental lithosphere. In order to verify whether high P/T (pressure/temperature) ratios recorded in the continental lithosphere can result from tectonic erosion, ablative subduction and recycling in the mantle wedge, we implemented a 2D numerical model to simulate oceanic subduction beneath a continent. Particular attention is paid to the role played by mantle hydration within the continental crust recycled in the wedge region. A comparison between hydrated and non-hydrated models highlights that hydration is fundamental in allowing the recycling of crustal material at shallow depths (≤150 km for a convergence rate of 1 cm year−1), making the uprising and exhumation of buried crustal material during active subduction possible. The recycled crustal material can originate from any crustal level. The Tmax and Pmax distributions within the final marker configuration show that crustal recycling induces the coupling of volumes that reached different depths during their paths in the corner flow. To verify the reliability of this model we compare predictions with natural geological data from the Austroalpine Sesia–Lanzo Zone (SLZ), the largest eclogite-facies crustal fragment of early Alpine age and whose Alpine tectonic evolution has been interpreted as compatible with a cycle of burial at depth and exhumation during active subduction of the oceanic lithosphere. The relationships between natural P–T estimates and predicted P–T values show that the simulated geodynamic scenario generates a thermal regime coherent with that affecting the subducted continental crust of the SLZ, which may have been stable for a long time during Alpine subduction, allowing the SLZ rocks to accomplish their burial and exhumation path under an active subduction regime
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
