Attraversamenti, spazio pubblico e CCTV. Surveillance Art e resilienza femminile
No full textIl presente contributo vuole esplorare il tema della viandanza urbana e, in particolare, interrogarsi sulla posizione del soggetto femminile e sulle pratiche di svelamento e resistenza messe in atto verso l’occhio macchinico delle videocamere di sorveglianza. Muovendoci nel delimitato perimetro della Surveillance Art, metteremo a tema il ruolo delle videocamere di sorveglianza nello spazio pubblico, convocando gli interventi che più hanno promosso una prospettiva critica1, e prediligendo l’autorialità femminile
Rethinking Catatonia: New Insights from the Autism Spectrum
No full textInitially conceptualized as a subtype of schizophrenia, catatonia has progressively been recognized to occur in a broad variety of conditions, as a kind of final common pathway for many severe men-tal disorders. There is a significant overlap between the fundamental symptoms of Autism Spectrum Disorder (ASD) and catatonia, and ASD can frequently complicate with catatonic states. While provocative, the hypothesis that neuroatypicality may represent the submerged structural piece un-derlying catatonic states is intriguing. Yet, the multifaced relationship between catatonia and ASD may provide new insights in the etiology and treatment of both disorders

A Lagrangian sub-grid model for the dispersion of clouds of tracers
No full textTurbulence models are expected to satisfy the conflicting requirements of accuracy and computational efficiency. Here we discuss a new model that was recently developed in order to accurately and efficiently describe the dynamic of a clouds of tracers particles in Large Eddy Simulations of homogeneous and isotropic turbulent flows. The models incorporates the multi-scale nature of time and space turbulent velocity correlations that are essential in order to correctly reproduce the relative dispersion of multi-particle clouds. The model can be seen as an off-grid solver for the Eulerian velocity field at the positions of a given number of Lagrangian tracers that self-consistently move with it. Extensions to non homogeneous and isotropic turbulence as well as to the dynamics of particles will be discussed
Settling of particles in homogeneous shear turbulence
No full textThe settling of (inertial) particles is studied in homogeneous shear turbulence. A drift velocity perpendicular to gravity is measured due to the interplay between the homogeneous shear turbulence and gravity acting on the particles. We introduce a model to predict and understand this phenomenon
Hydrodynamical turbulence by fractal fourier decimation
No full textWe present a systematic numerical investigation of high-resolution 3D isotropic and homogeneous turbulence resolved on a decimated set of Fourier modes. Fractal decimation acts to decrease the effective dimensionality of the flow by allowing triadic interactions only in a set of Fourier modes N(k) proportional to k^DF for large k. While keeping the symmetries of the original 3D Navier-Stokes equations unchanged, a dramatic change in small-scale statistics is detected at decreasing the fractal dimension DF . Already at fractal dimension DF = 2.8, a global self-similar behaviour is observed in the inertial range of scales, the consequence of such transition are the restoration of the scaling symmetry and vorticity distribution that becomes close to Gaussian. We relate the results to the different roles of local vs non-local interactions in the energy transfer range
Rifondare il tempo: il cinema di Chiara Cremaschi tra memorie fluttuanti e instabili presenti
No full textContributo dedicato alla pratica filmica e alla produzione di Chiara Cremaschi nel volume "CINEma oltre. Donne e pratiche audiovisive" in Italia volto ad indagare il panorama, ancora poco esplorato, delle attività delle artiste italiane che "dagli anni Settanta a oggi hanno scelto l'immagine in movimento come medium di espressione e talvolta di lotta". Muovendo tra Film Studies e Women's Studies, in un approccio multidisciplinare, il volume propone una selezione di artiste – dalle più conosciute alle emergenti note, emergenti – in un dialogo che interseca le esperienze storiche del cinema di ricerca e degli albori della videoarte, fino all'attualità degli ultimi anni, tenendo insieme le pioniere delle origini e le audaci sperimentatrici d'oggi. Il volume rappresenta uno degli output delle linee di ricerca che fanno perno nell'attività del Forum delle studiose di cinema e audiovisivi.

Neurosteroid Levels in GBA Mutated and Non-Mutated Parkinson’s Disease: A Possible Factor Influencing Clinical Phenotype?
No full textNeurosteroids are pleiotropic molecules involved in various neurodegenerative diseases with neuroinflammation. We assessed neurosteroids' serum levels in a cohort of Parkinson's Disease (PD) patients with heterozygous glucocerebrosidase (GBA) mutations (GBA-PD) compared with matched cohorts of consecutive non-mutated PD (NM-PD) patients and healthy subjects with (GBA-HC) and without (NM-HC) GBA mutations. A consecutive cohort of GBA-PD was paired for age, sex, disease duration, Hoehn and Yahr stage, and comorbidities with a cohort of consecutive NM-PD. Two cohorts of GBA-HC and HC were also considered. Clinical assessment included the Movement Disorder Society revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) and the Montreal Cognitive Assessment (MoCA). Serum samples were processed and analyzed by liquid chromatography coupled with the triple quadrupole mass spectrometry. Twenty-two GBA-PD (males: 11, age: 63.68), 22 NM-PD (males: 11, age: 63.05), 14 GBA-HC (males: 8; age: 49.36), and 15 HC (males: 4; age: 60.60) were studied. Compared to NM-PD, GBA-PD showed more hallucinations and psychosis (p < 0.05, Fisher's exact test) and higher MDS-UPDRS part-II (p < 0.05). Most of the serum neurosteroids were reduced in both GBA-PD and NM-PD compared to the respective control cohorts, except for 5α-dihydroprogesterone. Allopregnanolone was the only neurosteroid significantly lower (p < 0.01, Dunn's test) in NM-PD compared to GBA-PD patients. Only in GBA-PD, allopregnanolone, and pregnanolone levels correlated (Spearman) with a more severe MDS-UPDRS part-III. Allopregnanolone levels also negatively correlated with MoCA scores, and pregnanolone levels correlated with more pronounced bradykinesia. This pilot study provides the first observation of changes in neurosteroid peripheral levels in GBA-PD. The involvement of the observed changes in the development of neuropsychological and motor symptoms of GBA-PD deserves further attention
