Monitoring of TCA concentration in stoppers obtained by cork oak from different Sardinian areas
No full textA spatial and temporal distribution analysis of TCA biosynthesis phenomenon in the cork, through the use of both analytical data of sensory type and other instrumental determinations, was performed. By means of the sensory analysis, following the methodology of ISO 20752/2007 (E), it was determined the number of TCA-positive stoppers released and the percentage of caps with different defects. In each batch of caps, different scents have been identified: corked taste, mold, abnormal odor and doubt. The processed data from sensory analysis were broken down by geographic distribution and related to the instrumental determinations
Trasformazioni eterogenee atipiche e limiti all'autonomia privata
Get PDFThe Italian Civil Code provided for the change of companies’ form (“trasformazione”) ever since it was enacted in 1942. In particular, the law regulated the modification of partnerships (“società semplice” and “società in nome collettivo”) into corporations (“società per azioni” and “società a responsabilità limitata”). Despite the silence of the law, the modification of corporations into partnerships was also admitted.
Back in 2003, Italian corporate law was deeply reformed. As to the change of companies’ form, the new law has granted the possibility of modifying partnerships and corporations into other legal entities, including non-profit organizations (e.g., foundations, associations, etc.). The new regulation calls for a new approach by corporate scholars.
This work aims at studying in depth the implications brought by the new regulation, devoting attention to the extent of the “same-entity principle” (“principio di continuità”) and addressing the issue of those modifications of form that are not specifically envisaged by the law
Characterization and phylogenteic analysis of Usutu virus isolates in Sardinia
Get PDFFlaviviruses are Arbovirus, a group of viruses able to propagate both in Arthropodes and in Vertebrates, including human. Upon infection, human can develop a variety of signs such as encephalitis, meningitis and fever. Natural transmission cycle occurs between ornithophilic mosquitoes (vector) and birds that serve as reservoir or amplifying host. Our study focuses on the Usutu virus (USUV). USUV is an enveloped virus with a protein capside enclosing a positive-strand RNA genome with a size of about 11 kb. USUV was detected in Sardinia for the first time in 2013. Aim of the project is to detect USUV circulating in Sardinia through the screening of pools of mosquitoes caught with dedicated traps, and the monitoring of wild and sinanthropic birds. Viral full genomic sequencing through the technique of “primer-walking” with home designed primers is performed on viral variants obtained from positive samples. Viral strains molecular characterization and phylogenetic analysis is also performed by using dedicated software. Local strains are closely related to Italian strains and in particular with “Bologna 2009". We obtained the complete genome sequences of the isolates designated strains “91418_Sassari2013” and “62059_Sardegna2015”. We found some important molecular features, more of them associate with increase of virulence and capacity to infect mammals includes humans. Results have implications in the molecular epidemiology of Usutu virus in the Mediterranean area and in the study of pathogenicity of this Flavivirus
Documentare l’archeologia in 3 Dimensioni: problematiche e metodologie proposte
Get PDFThe research examines the technique and use of digital documentation for the interpretation of archaeological contexts: they were developed through the application of multi-scale three-dimensional technologies, photogrammetry and laser scanner, on two case studies.
The aim was to define a method based on the integration of available sources and to create a documentation that could follow international standards, ensuring scientific transparency and authenticity of digital sources.
In both cases the integration of sources, archaeological and historical, analogical and digital, has allowed a complete 3D documentation of the sites and some reconstructive hypotheses based on the interpretation of the elements emerging from the relief.
Using the same digital documents, it has been possible to reconstruct the monastic complex of Salvennor, disappeared today; a 3D and gaming modelling software was used to create an attractive virtual visit to the site of Sant'Imbenia, which may interest both the researcher and the great public
Use value of cultural events: the case of the Christmas markets
No full textThe Christmas market in Meran (Italy) is one of the top 27 European Christmas markets, attracting around 2000 visitors a day for 50 days. The Christmas market is a cultural and retail event that creates a recreational value for visitors. This paper, using the travel cost method, estimates the recreational use value of the Meran Christmas market for one-day and multiple-day visitors. The aim is to estimate the economic or social value (consumer surplus) of the Christmas market to understand in what way the event creates a benefit for society as a whole. The empirical data were collected via a survey administered at the end of a visit at the Christmas market during the 2011–2012 season. The empirical findings highlight that the use value differs—other than according to travel costs—according to the type of visit experience and to the perceived authenticity
Within-session decrement of the emission of licking bursts following reward devaluation in rats licking for sucrose
No full textWe previously observed that dopamine D2-like receptor blockade in rats licking for sucrose produced a within-session decrement of the emission of licking bursts similar to the effect of either reward devaluation, or neuroleptics, on operant responding for different rewards, which, accordingly, we interpreted as an extinction-like effect. This implies that exposing animals to reward devaluation would result in a drop of burst number taking place only after the contact with the devalued reward. To test this prediction, we compared the difference in the within-session time course of burst number in response to high (10%) versus low (2%) concentration sucrose solutions, either in a condition of reward devaluation (exposure to 2% after daily 10%), or in a condition which does not involve changes in the reward value (two groups of subjects each repeatedly exposed to only one of the two concentrations). Reward devaluation resulted in a within-session decrement of the burst number, with the response rate dropping only after the contact with the devalued reward, as predicted. This response pattern was reliably observed only in subjects at their first devaluation experience. In contrast, exposure of separate groups of animals to the two different concentrations yielded lower levels of burst number in the low concentration group apparent since the beginning of the session, as previously observed with dopamine D1-like receptor blockade. These results show that the analysis of burst number, but not of burst size, reveals a specific activation pattern in response to reward devaluation, which differs from the pattern observed comparing the response to two different sucrose concentrations in separate groups of subjects, i.e. in a condition not involving reward devaluation. Finally, the characterisation of the experimental measures of the analysis of licking microstructure in behaviourally (and psychologically) meaningful functional terms, might be relevant for the investigation of the mechanisms underlying behavioural activation and the related evaluation processes
Limites y controles al poder politico
No full textThis work presents a comprehensive and analytical study of the limits and regulations of political power proposed through the history of political philosophy from a theoretic perspective, presenting examples and references of real cases and institutions when regarded as necessary.
One of the main ideas of the work is the proposal of classification of such limits in four groups that can be fitted within certain historical periods: from Ancient Greece and Rome till Medieval Age (I); the liberal thinking of the XVIII and XIX centuries that leaded to modern constitutionalism (II); the contemporaneous constitutional texts promulgated on the afterwards of the IIWW (III); and finally, the transparency and accountability mechanisms gradually generated on the last three or four decades.
The other main idea is the inherent and practical necessity of controlling political power, regardless of the type of regime. As Stephen Holmes points out with the “paradox of limited power”, no regime can survive without the voluntary cooperation of the weaker individuals. This leads us towards the Platonic dilemma between the rule of law and the rule of men, whereas the law is considered as the best way for limiting power. <br/
Tecnologia della produzione ceramica nella protostoria della Sardegna: nnuovi contributi dalla necropoli di s'Elighe Entosu (Usini, Sassari)
Get PDFIn this work was applied the technological analysis to a selection of pottery fragments from the IV Tomb of S’Elighe Entosu necropolis. Main goal was to retrace the Operational Chains of artifacts by studying main types of macroscopic wears: Shape Variations, Surface Aspects, Inclusions Orientation and Distribution. The interpretative hypotheses were verified through a comparison with the data of previous studies and experimentation.
The analytical method applied has not been sufficiently exploited in the study of Sardinian prehistoric ceramics. The main problems related to the study were the high material fragmentation and the surface deterioration due to post-depositional phenomena, but the study has identified two main types of Forming: coiling and mixed (mould for bases and coils for walls and rims).
The study has identified some clear trends in the technical behaviors and a precise selection of the clay pastes for different shapes modeling
Bisogni, risorse, persona: il servizio sociale di fronte alla sfida della generatività
No full textGenerativity is a constitutive dimension of social work, that is announced in its
ethical bases but neglected in professional practice, in which the monetary intervention
and the professional provision prevail.
The research project was inspired by the “generative welfare” proposal and it is
divided in two main parts. The first part aims at deepening the understanding of the
processes of activation and empowerment of the people taken in charge by the social
service. The second part focuses on the possibility and feasibility of an approach to
social support endowed with more sociability.
The generativity approach has been dealt with from two different point of
view: the socio/anthropological and the social work one. The first perspective takes into
account such issues as relational goods, social capital and the dimensions of
subjectivity and significance. The second makes reference to the theories which
enlighten the importance of the valorisation of people's resources and the
constructionist approach.
The qualitative research involved Sardinia and Trentino, and was divided into two
levels. The first one involved the beneficiaries of the social work intervention:
their stories were collected in order to come in touch with their representations of the
condition they live, and their feelings about the support they received. The second level
involved the social workers of the two regions. Through the focus group methodology it
was possible to observe their representations about the social demand received by their
offices and the effectiveness of the interventions.
The empirical data underline the necessity to overcome a performance logic and
to move to forms of help and support that holds responsible those who receive them
Politica di coesione 2014-2020.<br/> Il sistema di governance per la gestione dei fondi della Regione Sardegna
No full textThis dissertation aims to study and analyze how the new 2014-2014 ESIF regulations (European Structural & Investment Funds), particularly ERDF (European Regional Development Funds) and ESF (European Social Funds), impact the governance system in the Autonomous Region of Sardinia (ARS) with regard to the management of EU resources for cohesion policy. Moreover, it investigates how the latter has responded to the EU's push towards reinforcing the administrative efficacy of actors responsible for managing European funds. More specifically, this work examines whether and how the Regional administration has changed in an effort to meet current needs for the simplification, consistency and transparency of fund management required by the new regulations; what difficulties were encountered in the process; what systems of coordination and interchange among involved parties (regional, national and European) were set in place; what measures were taken to meet the EU's demands for reinforcing administrative management; finally, what strengths and critical issues are evidenced in the new Regional organization
