Drawing and color in the 18th century frescoes of the church of Santa Susanna in Sardinia
No full textAt the beginning of the 18th century Sardinia had an important political and economic change due to the transfer of power from Spain to Piedmont. A change also occurred in culture and artistic production, but it was much slower. The work of Are’s family belong to this context. Pietro Antonio (the father) and Gregorio (the son) realized their works from 1678 to 1777 [1]. They worked in some villages in the district of Nuoro, such as Fonni, Orani, Triei and Tonara. We believe that Are’s family members are the authors of the Santa Susanna vault frescoes. The church is located in the rural village of Busachi in the district of Oristano. Looking at the frescoes in the majority of the buildings in the villages mentioned above, we can find similarities in style, design setting, use of color and painting technique. Moreover, the floral motifs and the various characters depicted in the scenes have strong similarities. This pictorial and decorative practice is common in several churches on the island. This artistic phenomenon was not studied by many scholars yet. Consequently, it is not possible, like in our case, to easily attribute the authorship of certain works. The intention of this paper is to suggest a graphic study of Santa Susanna’s frescoes vault in order to add an important element to the knowledge of these architectural and artistic practice. This research aims to go beyond the stylistic classification. Through survey and drawing we will highlight the dimensional aspects in order to rebuild perspective. Thus, we will analyze the color choices and the different compositions with the purpose to make an objective comparisons with other similar works. At last but not at least we will highlight the state of preservation of these artistic compositions

No full textCloud GIS and 3D modelling to enhance sardinian late gothic architectural heritage
No full textThis work proposes the documentation, virtual reconstruction and spreading of architectural heritage through the use of software packages that operate in cloud computing. Cloud computing makes available a variety of applications and tools which can be effective both for the preparation and for the publication of different kinds of data. We tested the versatil ity and ease of use of such documentation tools in order to study a particular architectural phenomenon. The ultimate aim is to develop a multi-scale and multi-layer information system, oriented to the divulgation of Sardinian late gothic architecture. We tested the applications on portals of late Gothic architecture in Sardinia.
The actions of conservation, protection and enhancement of cultural heritage are all founded on the social function that can be reached only through the widest possible fruition by the community. The applications of digital technologies on cultural heritage can contribute to the construction of effective communication models that, relying on sensory and emotional involvement of the viewer, can attract a wider audience to cultural content
Immunocytochemical study of the forebrain serotonergic innervation in Sardinian alcohol-preferring rats
No full textRationale: The anxiolytic effect of ethanol is generally considered to be causally related to the development of alcohol dependence, and serotonin (5-HT) has been involved in both alcohol abuse and anxiety disorders. Several lines of evidence suggest an inverse relationship between alcohol abuse and central serotonergic neurotransmission. Objectives: When tested in the elevated plus-maze, selectively bred Sardinian alcohol-preferring (sP) rats display a higher degree of anxiety than Sardinian alcohol-non-preferring rats (sNP); this behavior is reversed by voluntary ethanol intake. The present study examined whether sP rats differed with respect to the 5-HT innervation in different forebrain areas. Methods: We performed an immunohistochemistry study using an antibody raised against serotonin transporter (SERT), a marker for 5-HT fibers, coupled with an unbiased stereology, the method used to count the number of 5-HT neurons in the raphe nuclei. Results: The SERT-positive innervation density was found to be significantly lower in the medial-prefrontal cortex and in the shell of the nucleus accumbens of the ethanol-naive sP rats (sP-N) when compared with the sNP and unselected Wistar rats. No differences were found in the caudate putamen and hippocampus. The stereological analysis showed a significant difference in the number of 5-HT neurons in the dorsal but not in the median raphe of sP-N rats, compared with sNP and Wistar rats. Analysis of the cell body cross-sectional area revealed no differences among the three lines of rats either in the dorsal or in the median raphe. In sP rats that had voluntarily drunk ethanol for 14 consecutive days (sP-exp), no differences were found in the 5-HT innervation relative to sP-N animals. Conclusions: These results indicate a selective reduction of innervation in the medial portion of the mesocorticolimbic 5-HT system in sP rats, suggesting that this genetically determined difference may be involved in the contrasting alcohol preference and consumption of sP and sNP animals
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
