Rethinking Romanzo Rosa: The first person narrator and changing gender roles in Brunella Gasperini’s rosso di sera

Questo articolo analizza l’uso del narratore autodiegetico e del punto di vista maschile in Rosso di sera, un romanzo di Brunella Gasperini (Bianca Robecchi, 1918-1979) pubblicato all’inizio degli anni Sessanta. Grazie a tali scelte narrative, Gasperini riesce a costruire un romanzo estremamente innovativo nel panorama della narrativa popolare rivolta a un pubblico femminile. Mentre il racconto in prima persona facilita l’identificazione delle lettrici con la voce narrante, il punto di vista maschile interviene a complicare tale identificazione, aprendo una riflessione sulle identità femminili nell’Italia del boom economico e la loro rappresentazione nella narrativa di genere

Structural validity and classification performance of the Italian Short Negative Acts Questionnaire: A Structural Equation Modeling approach for building ROC curves

We investigated the structural (internal) validity and classification performance of the Italian Short Negative Acts Questionnaire (SNAQ), a 9-item self-report instrument assessing bullying at work. Consistent with recent attention of researchers to control measurement error in predictive models (Jacobucci & Grimm, Perspectives on Psychological Science, 15(3), 809–816 2020), classification performance was investigated through a proposed novel procedure that uses Structural Equation Modeling for building ROC curves. Participants included 357 workers (females = 50.4%) from various sectors. Our results showed that (a) the Italian SNAQ demonstrates adequate levels of structural validity; (b) its classification performance (in terms of self-labeled bullying) is outstanding; and (c) the ROC curves estimated by means of Structural Equation Modeling outperform those estimated with classical observed-variable approaches. In conclusion, we provided further evidence regarding the good psychometric properties of the Italian SNAQ and we also offered a novel approach for estimating ROC curves that does not neglect the issue of measurement quality

Localization in the Discrete Non-linear Schrodinger Equation and Geometric Properties of the Microcanonical Surface

It is well known that, if the initial conditions have sufficiently high energy density, the dynamics of the classical Discrete Non-Linear Schrodinger Equation (DNLSE) on a lattice shows a form of breaking of ergodicity, with a finite fraction of the total charge accumulating on a few sites and residing there for times that diverge quickly in the thermodynamic limit. In this paper we show that this kind of localization can be attributed to some geometric properties of the microcanonical potential energy surface, and that it can be associated to a phase transition in the lowest eigenvalue of the Laplacian on said surface. We also show that the approximation of considering the phase space motion on the potential energy surface only, with effective decoupling of the potential and kinetic partition functions, is justified in the large connectivity limit, or fully connected model. In this model we further observe a synchronization transition, with a synchronized phase at low temperatures

Intraductal papillary mucinous neoplasms of the pancreas: Uncommon imaging presentation, evolution and comparison of guidelines

Pancreatic cystic lesions are often asymptomatic, incidentally detected and include a range of entities with varying degrees of concern for malignancy. Among these, intraductal papillary mucinous neoplasms (IPMN) are considered premalignant pancreatic lesions, with a broad pathological spectrum ranging from lesions without dysplasia, which can be managed conservatively, to malignant lesions that require surgical resection. The increasing use of CT and MRI has led to increased recognition of this entity incidentally, with branch-duct IPMN representing the most common subtype and the most challenging lesions in terms of patient management. The main imaging modality involved in diagnosis and surveillance of IPMN is MRI. Radiologists play an important role in the management of patients with IPMN, including lesion detection, characterization, follow-up and prognostication, allowing early MRI identification of features that are concerning for malignancy. The main aim of this pictorial review is to illustrate MRI features of IPMN and to discuss risk stratification scores based on different guidelines, with a main focus on branch-duct IPMN. The secondary aims include the presentation of common and uncommon imaging evolution of BD-IPMN as well as the discussion on current controversies on the appropriate management of IPMN

Changes in insulin sensitivity in response to different modalities of exercise: a review of the evidence

Summary: Type 2 diabetes is an increasingly prevalent condition with complications including blindness and kidney failure. Evidence suggests that type 2 diabetes is associated with a sedentary lifestyle, with physical activity demonstrated to increase glucose uptake and improve glycaemic control. Proposed mechanisms for these effects include the maintenance and improvement of insulin sensitivity via increased glucose transporter type four production. The optimal mode, frequency, intensity and duration of exercise for the improvement of insulin sensitivity are however yet to be identified. We review the evidence from 34 published studies addressing the effects on glycaemic control and insulin sensitivity of aerobic exercise, resistance training and both combined. Effect sizes and confidence intervals are reported for each intervention and meta-analysis presented. The quality of the evidence is tentatively graded, and recommendations for best practice proposed

Clinical, magnetic resonance imaging, and histopathologic features of a hypoglossal malignant peripheral nerve sheath tumor in a maltese dog

Malignant tumours arising from peripheral nerves or displaying differentiation along the lines of the various elements of the nerve sheath are collectively referred to as MPNSTs. Histologically, in human MPNST, the malignant nature of these tumours is associated with an infiltrative and cellular proliferation of atypical, mitotically active spindle cells. Their predilection for sites varies with the species. In dogs the most common site for MPNST is the nerve roots or nerves of the brachial plexus, while the cranial nerve more frequently involved is the trigeminal nerve. In humans, hypoglossal peripheral nerve sheath tumours are rare, only few cases are described in literature; and the malignant forms are even exceptional. Fifty per cent of cases displayed both an intra- and extracrania component, and are referred as dumbbell-shaped tumours. To our knowledge this is the first case report an hypoglossal MPNST in a dog. In our case the tumour was dumbbell-shaped, with both intra-and extracranial components and associated with characteristic clinical signs of hypoglossal tumour. The malignant histological appearance of the lesion occurred without infiltrative growth

Automatic Segmentation of Posterior Pole Retinal Layers In Patients with Early Stage Glaucoma Using Spectral Domain Optical Coherence Tomography

Purpose: To measure Ganglion Cell Layer (GCL) and Retinal Nerve Fiber Layer (RNFL) thickness of the retinal posterior pole in patients with early stage primary open-angle glaucoma (POAG) using the new automatic segmentation technology of spectral domain optical coherence tomograph (SD-OCT). Methods: 37 clinical records of patients with early glaucoma (grade 1 to 2 according to the Glaucoma Staging System 2) and 40 age and sex-matched controls were considered in this case-control observational retrospective study. Automated segmentation of GCL and RNFL was performed in one randomly selected eye from the electronic OCT records of each participant using the new Spectralis SD-OCT segmentation technology (Heidelberg Engineering, Inc., Heidelberg, Germany). Thickness of different retinal layers was obtained from each Posterior Pole volumetric scan. Measurements of the peripapillary RNFL thickness (pRNFLt) were also obtained and then compared with those of posterior pole RNFL thickness (ppRNFLt). Results: Both GCL and RNFL were significantly thinner at the retinal posterior pole in the POAG group as compared to the control group (p<0,0001). Furthermore, pRNFLt was significantly thinner in the glaucoma group as opposed to the control group (p<0,0001). Measurements of pRNFLt were significantly correlated with those of the ppRNFLt (Pearson’s coefficient r=0.863). Conclusions: The new Spectralis SD-OCT automatic segmentation tool may be useful in evaluating structural damage in patients with early glaucoma, by providing complementary measurements to the clinical assessment of glaucoma that could be used in conjunction with other relevant parameters in the diagnosis and the evaluation of the progression of the disease

Clinical, magnetic resonance imaging, and histopathologic features of hypothalamic neuronal hamartoma in a young vizsla

Hypothalamic hamartomas (HH) are rare, tumor-like malformations thatoccurduring fetal development and are present at birth. They differ from neoplasms since they are not autonomous and they grow in proportion to normal brain growth, and consequently their relative size to the rest of the brain is the same for the lifetime of the patient. Hamartomas are non-progressive lesions and do not expand, spread or metastasize to other locations. In canine nervous system, vascular, neuronal and peripheral nerve fibers hamartomas have been described; to our knowledge, this is the first report describing the MRI features of a hypothalamic neuronal hamartoma in a dog

Patrimonio y práctica arqueológica en el museo José M. Maciel de la ciudad de Coronda (pcia. de Santa Fe)

En este trabajo se dan a conocer las gestiones patrimoniales que se vienen llevando a cabo en el Museo José M. Maciel de la ciudad de Coronda (Santa Fe). Las interacciones entre el equipo de arqueólogues y el museo comenzaron en el año 2009 y se fueron cristalizando en diferentes acciones conjuntas: excavaciones arqueológicas, charlas abiertas a la comunidad, muestras permanentes y temporarias, sistematización de colecciones, estudios específicos de restos arqueológicos, entre otras. Un eje transversal a todas las actividades lo constituye el vínculo con la comunidad de pueblos originarios Corondá quien, a través de su cacique, Sr. Claudio Ñañez, ha participado activamente, tanto en campañas arqueológicas como en la elaboración de muestras y talleres. Como resultado de este recorrido, el museo fue repensado con una mirada crítica, al igual que la práctica arqueológica, la cual busca ser entendida como un quehacer dinámico de trabajo que incluya a los diferentes actores sociales vinculados con el patrimonio.This paper presents the heritage management that has been carried out in José M. Maciel museum of Coronda city (Santa Fe). The interactions between the archaeological staff and the museum began in 2009 and have been crystallized in different joint actions: archaeological excavations, talks open to the community, permanent and temporary exhibitions, systematization of collections, specific studies of archaeological remains, among others. A transversal axis to all the activities is the link with the Corondá community indigenous people. Through their chief, Mr. Claudio Ñañez, this community has actively participated both in archaeological campaigns and in the preparation of samples and workshops. Because of all these activities, the museum was rethought with a critical eye, as well as the archaeological practice; the latter seeks to be understood as a dynamic job that includes different social actors linked to heritage.Fil: Sartori, Julieta Isabel.
