Simone Varriale, Globalization, Music and Cultures Of Distinction, The Rise of Pop Music Criticism in Italy, London, Palgrave Macmillan, 2016
No full textThis review - of the volume by Simone Varriale, Globalization, Music and Cultures Of Distinction, The Rise of Pop Music Criticism in Italy, London, Palgrave Macmillan, 2016- focuses on the rise of Italian pop music criticism as a new cultural institution which, according to the author, contributed to the “artistic legitimation” of popular music and culture between 1969 and 1977, particularly of American and British pop-rock in Italy. It is a study which, using an interdisciplinary approach, also aims to promote an historical research about the rise of the Italian music press
Study of the inclusive, socio-relational and educational dynamics of students with visual disabilities in the school context
No full textStudents experiencing visual impairment have reported feelings of inadequacy in terms of school inclusion and encounter difficulties in establishing social connections with both teachers and peers. These difficulties have a detrimental impact on various aspects of their educational experiences, particularly their academic progress. In this regard, conducted two empirical inquiries aiming to explore two specific social inclusion dimensions within the educational setting: school integration and forming close relationships within the school en-vironment. Furthermore, the studies sought to analyze the correlation between school be-longing and self-esteem, as well as the connection between establishing close relationships at school and achieving academic inclusion. The recruitment for both studies encompassed students with varying levels of visual impairment, ranging from severe impairment to mild impairment, along with sighted students. The students were tasked with completing ques-tionnaires focused on exploring aspects such as school belonging, close relationships within the school environment, self-esteem, and academic inclusion. The results of the study re-vealed that students with visual impairment reported feeling significantly less socially included in comparison to their counterparts. The sense of school belonging was found to have a notable influence on specific dimensions of self-esteem, while the quality of social relation-ships with close friends had a significant impact on academic inclusion. There were no dis-cernible group disparities identified in terms of self-esteem and the cultivation of close social connections between students with and without vision impairment. The research underscored the school experiences of students with visual impairment, emphasizing the beneficial role of school inclusion in their academic journey and socio-emotional growth. It was observed that students facing visual impairment encounter socio-emotional obstacles within the school setting, warranting attention in future research and practical interventions
A bilevel approach to ESG multi‐portfolio selection
No full textWe rely on bilevel programming to model the problem of financial service providers that, in order to meet stakeholders’ demands and regulatory requirements, aim at incentivizing accounts’ holders to construct ESG-oriented portfolios so that the overall ESG impact of the firm is optimized, while the preferences of accounts’ owners are still satisfied. We analyze this complicated framework from a theoretical point of view and identify sufficient conditions that make it numerically tractable via a novel, specifically tailored algorithm, whose convergence properties are studied. Numerical testing on real-world data confirms the theoretical insights and shows that our model can be solved even when dealing with considerable problem sizes

Surgical treatment of chronic acromioclavicular dislocation with biologic graft vs synthetic ligament: a prospective randomized comparative study
No full textBackground: Acromioclavicular (AC) dislocation involves complete loss of articular contact; it is defined as chronic when it follows conservative management or unsuccessful surgical treatment. Materials and methods: The study compared the clinical and radiographic outcomes of AC joint stabilization performed in 40 patients with chronic dislocation using a biological allograft (group A) or a synthetic ligament (group B). Demographic data included: M/F: 25/15; mean age: 35 ± 3.2 years; previous surgery in 11 patients, including Weaver-Dunn (3), coracoacromial ligament repair (4), stabilization with K-wires (4). Dislocation was type III in 14 (35 %) and type IV in 26 (65 %) patients. Clinical assessment was with the Constant-Murley score (pre- and postoperative) and with the modified UCLA score. Enrollment started in January 2004 and was completed in March 2008. Patients were evaluated at 1 and 4 years. Postoperative X-rays were examined to assess joint stability in the coronal and axial planes, coracoclavicular ossification, and signs of AC joint osteoarthritis and distal clavicular osteolysis. Results: The "biological" group achieved significantly better clinical scores than the "synthetic" group at both 1 and 4 years. Poor subjective satisfaction and lower clinical scores were found in the 3 patients (1 from group A and 2 from group B) who experienced complete postoperative dislocation. No significant correlations were found with other radiographic parameters. Conclusions: The biological graft afforded better clinical and radiographic outcomes than the synthetic ligament in patients with chronic AC joint instability. Fixation to the clavicle constitutes the main weakness of both approaches and needs improving. © 2012 The Author(s)
Ccdc6 knock-in mice develop thyroid hyperplasia associated to an enhanced CREB1 activity
No full textCCDC6 was originally identified upon rearrangement with RET in human thyroid papillary carcinomas generating the RET/PTC1 oncogene. We have previously reported that CCDC6 interacts with CREB1 and represses its transcriptional activity. Since the function of at least one allele of CCDC6 is lost following RET/PTC1 rearrangements, we aimed at the generation of mice, carrying a CCDC6 mutant gene. Previous studies suggested that the coiled-coil domain of CCDC6, mainly encoded by human exon 2, is required for the protein function. Therefore, we engineered a murine Ccdc6 construct, carrying a deletion of the exon 2, that was able to exert only a mild repression on CREB1 transcriptional activity, with respect to the wild type Ccdc6. Subsequently, we generated Ccdc6-ex2 knock-in mice. These mice developed thyroid hyperplasia associated with an enhanced CREB1 activity and an increased expression of the CREB-1 regulated genes. These results strongly support a CCDC6 promoting role, ascribed to its functional impairment, in the development of thyroid papillary carcinomas harboring the RET/PTC1 oncogene
Arthroscopic treatment of early glenohumeral arthritis
No full textBackground: The articular cartilage of the shoulder is not endowed with intrinsic repair abilities, so the detection of chondral lesions during arthroscopy may indicate that additional articular procedures are needed. The aim of the current study was to evaluate the benefits of arthroscopy in patients with early shoulder arthritis, and to assess which clinical and radiological features are correlated with better arthroscopic outcomes. Materials and methods: Out of a total of 2,707 shoulders, 61 arthroscopies were performed on patients aged 30-55 years suffering from a painful early arthritic shoulder. We performed a retrospective study of 47 of those 61 patients with osteoarthritis at Samilson-Prieto stage I or II. SST and Constant score were used as outcome measures. Arthroscopic circumferential capsulotomy was performed to release the soft tissues and increase the joint space. Glenoid chondral lesions were caregorized according to location (anterior, posterior, centered) and size (small, large, total) and treated with microfractures; in the last 11 patients, we placed a engineered hyaluronic acid membrane, Hyalograft® C, on the surface of the glenoid. Postoperative care included mobilization the day after surgery, with the arm protected in a sling for two weeks. Follow-up examinations were performed at 3, 6, 12, and 24 months after surgery. The clinical and radiographic data collected were compared with those obtained at the last examination. Results: The mean Constant score increased from 43.8 points to 79.1, and the mean SST score increased from 4.9 points to 9.4 points. Clinical outcomes improved significantly in 44 patients (93.6 %). The three patients (6.4 %) with the lowest scores showed progression of arthritis. Age, gender, glenohumeral distance, and presence of engineered hyaluronic acid membrane were not related to clinical scores. Recovery of range of motion as well as small and centered cartilage lesions were statistically associated with improved outcome. Conclusion: The main finding was that soft tissue procedures (including capsulotomy and synovectomy) associated with glenoid microfractures are only suitable for patients with early arthritis and preserved humeral head shape, particularly in cases with small and centered glenoid cartilage lesions. © 2012 The Author(s)
GENDER AND COMMUNITY IN THE ORAL AND IN THE WRITTEN
No full textInternational audienceThe central question addressed in this paper is how categories of gender and community affect each other (1). This question is looked at in one of the preferred fields for intellectual constructions and interpretations, that of literary narratives. The relationship between gender and community is examined in a corpus of Kabyle oral narratives and in novels written in French by women writers from Kabylia (Algeria). These genres are heterogeneous in mode of production (oral, written) and language (Kabyle, French), but they can be included in what the author calls a 'Kabyle literary space', which permits a recognition of the interactions and intersections of materials that cannot be understood, interpreted, or even enjoyed were they to belong to two discrete systems
