Publishing and printing in Italy and the single internal market

Despite the anticipated fall of customs barriers in 1992, linguistic differences among European cultures will persist. English-language publishing will increase its presence, particularly in science and technology. Concentration will increase. But the penetration of the Italian market is not one-sided: Italian publishers, too, have entered other markets. The Italian printing industry is healthy, growing, and competitive worldwide. Gianni Merlini is president and CEO of Unione Tipografico-Editrice Torinese (UTET). His 1952 law degree thesis on “The Publishing manager and managing director before becoming president in 1975. He is active in numerous European associations in the fields of printing and publishing. UTET will celebrate its two-hundredth anniversary in 1991 and has been in Dr. Merlini's family since its founding.     

The Official Institutions for the Promotion of Educational Change in Italy

The author describes the formal structures which have been established to support the process of educational change in Italy.

There is a sound legislative base: a series of laws passed since 1973 create both a new model of school and the procedures and organisations designed to facilitate its emergence, including councils at the class and school level. The right and duty of teachers to engage on in‐service education is firmly recognised as an essential component in school development.

The European Centre for Education and the Pedagogical Documentation Library are mentioned, but the author dwells at greater length on the Regional Institutes for Educational Research, Experimentation and In‐Service Training (IRRSAE). He provides a detailed explanation of the duties of the IRRSAE and of their organisation and functioning.

The IRRSAE are widely regarded as key institutions in educational development in Italy.     

Connecting user and item perspectives in popularity debiasing for collaborative recommendation

Recommender systems learn from historical users’ feedback that is often non-uniformly distributed across items. As a consequence, these systems may end up suggesting popular items more than niche items progressively, even when the latter would be of interest for users. This can hamper several core qualities of the recommended lists (e.g., novelty, coverage, diversity), impacting on the future success of the underlying platform itself. In this paper, we formalize two novel metrics that quantify how much a recommender system equally treats items along the popularity tail. The first one encourages equal probability of being recommended across items, while the second one encourages true positive rates for items to be equal. We characterize the recommendations of representative algorithms by means of the proposed metrics, and we show that the item probability of being recommended and the item true positive rate are biased against the item popularity. To promote a more equal treatment of items along the popularity tail, we propose an in-processing approach aimed at minimizing the biased correlation between user-item relevance and item popularity. Extensive experiments show that, with small losses in accuracy, our popularity-mitigation approach leads to important gains in beyond-accuracy recommendation quality.     

Machine learning techniques for XML (co-)clustering by structure-constrained phrases

A new method is proposed for clustering XML documents by structure-constrained phrases. It is implemented by three machine-learning approaches previously unexplored in the XML domain, namely non-negative matrix (tri-)factorization, co-clustering and automatic transactional clustering. A novel class of XML features approximately captures structure-constrained phrases as n-grams contextualized by root-to-leaf paths. Experiments over real-world benchmark XML corpora show that the effectiveness of the three approaches improves with contextualized n-grams of suitable length. This confirms the validity of the devised method from multiple clustering perspectives. Two approaches overcome in effectiveness several state-of-the-art competitors. The scalability of the three approaches is investigated, too.     

Is there a real diagnostic impact of elastosonography and contrast-enhanced ultrasonography in the management of thyroid nodules?

Ultrasonography(US) and the new applications US elastography(USE) and contrast-enhanced US(CEUS) are used in the screening of thyroid nodules,for which fine-needle aspiration biopsy(FNAB) is the best single diagnostic test.The aim of the study was to compare the sensitivity,specificity,positive predictive value(PPV),and accuracy of the four examinations in nodules with cytological and histological diagnoses.The study used data from US,FNAB,USE(elasticity(ELX 2/1) index),and CEUS(Peak index and time to peak(TTP) index) evaluated in 73 thyroid nodules in 63 consecutive patients likely to undergo surgery.Cytological-histological correlation was available for 38 nodules.No correlation emerged between nodule size and cytological results.A significant(P=0.03) positive correlation between cumulative US findings and cytological results was found.In addition,significant correlations between cumulative US findings and cytology(P=0.02) and between cumulative US findings and histology(P<0.0001) were found.US showed the best specificity and PPV,and FNAB the best sensitivity.There was no significant difference in the ELX 2/1 index,Peak index,or TTP index among nodules subdivided according to cytological scores.No significant correlation was found between ELX 2/1 index,Peak index,and TTP index,on the one hand,and nodule size,US cumulative findings,cytology,and histology on the other hand.The sensitivity of the ELX 2/1 index was high,but its specificity was very low.The accuracy and PPV of USE were lower than those of the other procedures.Only the correlation between Peak index and cumulative US findings reached a value close to significance.Our ultimate aim is to minimise unnecessary thyroidectomy.US and FNAB continue to play a central diagnostic role.The use of a US score showed high specificity and PPV.The specificity of FNAB was low in this selected series because of the numbers of indeterminate cytological responses.USE and CEUS are innovative techniques that need to be standardized.The ELX 2/1 index,Peak index,and TTP index seem to be unrelated to histology.The best statistical data on USE and CEUS concerned their sensitivity and PPV,respectively.At present,USE and CEUS are too time-consuming and of limited utility in selecting patients for surgery.     

Speciation through entrepreneurial spin-off: The Acorn-ARM story

Can the concept of speciation explain evidence on how technologies branch and advance? Can evidence on innovation through spin-off usefully inform the concept of speciation? These questions are addressed through a case study of detailed processes enabling the shift of technology to new domains of application. An innovative IT firm developed its own semiconductor technology to remedy supplier deficiencies but it required a joint venture with a completely new business model to adapt and move the technology into new market domains. We propose the concept of techno-organizational speciation to delineate this phenomenon. Competing perspectives on speciation (compatibility, niche and lineage approaches) are found to illuminate the evidence, while complementarities between these conceptual dimensions are revealed by the case. Causal processes uncovered include the following: (1) Techno-organizational speciation through spin-off may be needed to launch a dominant technical standard, compatible with multiple applications. (2) This can be achieved through niche creation from which develops a new business ecosystem. (3) Inherited knowledge together with organizationally based learning foster the branching and renewal of technological lineages.     

Student politics in Italy: From Utopia to terrorism

Since 1968, the Italian student movement has moved from a stress on a libertarian Utopia to its current emphasis on support for political terrorism. This article presents an analysis of the social and economic crisis in Italy and indicates how the crisis has stimulated this change in the student movement. The crisis affects young people directly and this has deepened its impact in the universities. The student movement has experienced a collapse of representative student institutions, the rise of dogmatism and sectarianism, and the glorification of violence as a means of social change.     

Structural engineering and geology applied to the static problems of the Etruscan “Tomba dell’Orco” (Tarquinia,Central Italy)

The Etruscan Tomba dell’Orco was discovered in 1868. However, soon after discovery, part of its ceiling collapsed. An investigation was thus conducted with a view to assessing its safety conditions and permitting visitors’ access. Petrographic and physico-mechanical features of the local weak sandstones and mechanically more resistant calcareous sandstones “macco” were determined. Field mapping, drill-holes and geophysical prospecting helped reconstruct the stratigraphy of the volume where the tomb was excavated. The stability of the tomb basement is given by a thick macco layer. A few dm macco layer was identified above the ceiling. A model was then prepared with the Plaxis 2D V8.6 software. The safety coefficients calculated along two cross-sections of the tomb indicated that the margins for the tomb stability are reasonable.
