An assessment of customer’s preferences and improve brand awareness implementation of Social CRM in an Automotive company
No full textThe huge amount of online conversations that arises from the new means of communication between users, if analyzed and capitalized, is an important resource for companies and brands alike. Thus, a fundamental tool for the management of the relationship with customers such as CRM seems to be exceeded. The concept of a Social CRM platform was born with the objective of filling the gap between brand and customers connected to various social networks, allowing both parties to achieve tangible benefits from active participation. The key objective of this research involves the implementation of a Social CRM system, which is not yet present on the automotive market. The work starts through the identification and implementation of an experimental prototype that can define and highlight a methodological and technological best practice in the integration of heterogeneous components of an information system composed of independent software and continues with the definition of an integrated system that allows innovative Business Intelligence activities
Evaluation of Student Performance in adaptive e-learning processes with active tutorship
No full textHow could data mining help the development of e-learning methodologies? How could an instructional designer take benefit from the use of adaptive learning? How could adaptive learning be implemented in an Open Source platform? In this paper will be described the implementation of adaptivity technology in a specific, Open Source, Learning Management System (LMS). After a preliminary study about the adaptive features already built-in and the capabilities ready to perform a suitable student modeling, the research team extended those capabilities with a specific data model, student model and tutoring engine to perform automatic monitoring and sequencing of Learning Objects for each particular learner. Testing activities has proven the efficiency method in content and course delivery and give the opportunity to further develop a predicting tool based on data mining student modeling. This provides an efficient tool in tutorhisp activities. This paper describes some best practices developed during a Tempus IV Project granted by EU
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
I materiali vitrei di Herdonia (Foggia, Italia): studi di caratterizzazione e ipotesi di provenienza
No full textThe sample set from the cistern of the domus B consists of 21 glass sherds (cups, lamps, glasses/lamps, goblets, jugs/bottles,
unidentified typologies) and 4 production wastes dated to the first half of the 5th century A.D. They are characterised by various
shades of colour (yellow, olive-green, green-yellow, yellow-red, blue-green, blue, green, light and dark green), but colourless
glass is also represented. Samples were analysed by optical microscopy (MO), scanning electron microscopy (SEM-EDS),
electron Probe Micro Analysis (EPMA), X-ray fluorescence (XRF), inductively coupled plasma optical emission spectrometry
(ICP-OES), inductively coupled plasma mass spectrometry (ICP–MS) and instrumental neutron activation analysis (INAA) in
order to characterise both the texture and composition of glasses, and to identify vitrifying, stabilizing, flushing and colouring
agents. Our data were compared with those available in the literature in order to investigate the provenance of materials.
All finished products were produced from a mixture of siliceous sand and natron; however, they can be divided into GROUP A,
comprising yellow, olive-green and green-yellow glasses, and GROUP B, represented by yellow-red, colourless, blue-green,
light green and blue glasses. GROUP A is characterised by lower SiO2, K2O and CaO contents and higher Na2O and MgO contents
than GROUP B, suggesting a different source of sand and a different recipe. Furthermore, Sr and Zr contents seem to
indicate for GROUP A the use of shell and a different sand from that of the Levantine coast, while for GROUP B the employment
of a Levantine sand rich in shell. The colour of the artefacts is probably due to both the Fe3+/Fe2+ ratio and Fe2O3 and MnO
contents, but further studies on the oxidation state of Fe will be necessary to clarify the question. Unfinished products were produced
from natron and a siliceous sand and have an intermediate composition with respect to GROUPS A and B, even if more
similar to GROUP B. Flushing contents indicate a Na2O-richer recipe or shorter production cycle with respect to finished products.
As for colorants, the considerations relative to the finished products are also valid for unfinished products.
As for the provenance of materials, GROUP A shows analogies with glasses included in the HIMT group (Carthage,
Cyprus) of unknown origin. The composition of GROUP B samples is similar to that of Levantine glasses, suggesting an
import of raw glass or artefacts from the Syro-Palestinian coast. They were apparently produced from Belus sand mixed
with natron. Lastly, although the provenance of unfinished products is unclear, they are compositionally similar to the
glasses produced from natron and Belus sand
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
Late Antique Glass Vessels and Production Indicators from the Town of Herdonia (Foggia, Italy): New Data on Cao-Rich/Weak HIMT Glass
Full text linkIn the framework of the archaeometric research on Apulian Late Antique glass, a collection of 24 glass vessels (third to seventh centuries ad) and production indicators found at Herdonia (Foggia, Italy) was examined, by means of SEM–EDS, EMPA, ICP–MS and LA–ICP–MS. A fragment of crucible was further investigated by SEM–EDS and EMPA. The results obtained were discussed together with another glass collection from Herdonia previously investigated. The full set of 48 samples was made of siliceous sands mixed with plant ashes (two samples: a dark green slab and a colourless beaker/lamp) or natron (all the other 46 samples). The latter were assigned to the following compositional groups: HIMT, Levantine 1, RNCBGY1, RNCBGY2, RC/LAC-Sb, intermediate HIMT/RNCBGY1, intermediate RNCBGY1/HIMT, intermediate Levantine/RNCBGY2 and two other groups, the CaO-rich HIMT and the CaO-rich/Na2O poor HIMT, which showed a prevailing Adriatic distribution and a close similarity to the weak HIMT glass group. Most Herdonia samples were similar to the HIMT productions, and thus of likely Egyptian origin, while a smaller number of samples referred to the Levantine productions
