Le complexe de la complexité : déplacement multidimensionnel dans l’œuvre de Dai Sijie
No full textIl n’est plus possible de tracer les contours de la littérature chinoise en tant qu’entité « située » dans un espace bien défini. La littérature elle-même est désormais déterritorialisée. Une manifestation évidente de ce déplacement au sens large est la littérature de la diaspora, en particulier dans le cas où elle est rédigée dans une langue étrangère. Dans le contexte francophone, Dai Sijie est l’un des auteurs les plus connus parmi les écrivains assimilables à la diaspora chinoise et, parmi d’autres, son roman Le Complexe de Di (2003) constitue un excellent exemple de la manière dont la question du déplacement de l’individu peut être abordée depuis plusieurs perspectives. Cet article vise à montrer les différents niveaux auxquels l’auteur exprime sa transidentité et son hybridation linguistique et culturelle. Il explore trois interprétations d’un mouvement qui est à la fois linguistique, culturel et spatial, pour montrer le lien entre la représentation de l’espace et la complexité identitaire dérivant d’une « sinité » mondialisée.It is no longer possible to trace the contours of Chinese literature conceived as an entity “located” in a well-defined space. Literature itself is now deterritorialized. A clear manifestation of this displacement in the broad sense is the literature of the diaspora, in particular when it is written in a foreign language. In the French context, Dai Sijie is one of the best-known authors ascribable to the Chinese diaspora and, among the others, his novel Le Complexe de Di (2003) constitutes an excellent example of how the issue of the individual’s displacement can be represented from several perspectives. This article aims to show the different filters through which the author expresses his transidentity as well as by his linguistic and cultural hybridization. It explores three interpretations of a movement that is simultaneously linguistic, cultural and spatial, to investigate the link between the representation of space and the identity complexity deriving from a globalized “Chineseness.
Migration, society, and education: the case study of the former Officine Reggiane
No full textIl contributo affronta il rapporto tra migrazione, marginalità e progettualità educativa all’interno di un percorso di accoglienza migratoria svolto nella città di Reggio Emilia. Il progetto, in cui uno degli autori lavora e su cui è stato svolto un percorso di tesi che ha considerato un arco di sette anni, si è svolto sul caso delle ex Officine Reggiane, un contesto particolarmente segnato da marginalità e devianza su cui un lavoro di rete con professionalità integrate ha coinvolto un segmento importante di riflessività relativamente all’impatto dei fenomeni migratori nello specifico contesto. Il lavoro muoverà da una ricostruzione, nella prospettiva di una pedagogia critico-strutturale, delle condizioni educative nel contesto, proponendo una prospettiva di analisi sull’intersezione tra colonialismo, imperialismo e globalizzazione. Successivamente, tramite una disamina qualitativa strutturata attraverso analisi di caso, verranno delineati i caratteri fondamentali della ricerca svolta presso le ex Officine Reggiane. Infine, verranno discussi i temi pedagogici emergenti dalla disamina e delineate le possibili linee di evoluzione e di intervento nel contesto.This contribution explores the relationship between migration, marginalization, and educational planning within a migration reception program implemented in the city of Reggio Emilia. The project, in which one of the authors actively participates and which forms the basis of a seven-year thesis, focuses on the case of the former Officine Reggiane, an environment characterized by marginalization and deviance. A network of integrated professionals actively collaborates on this project, fostering significant reflection on the impact of migration phenomena in this specific context. The study commences by reconstructing the educational conditions within the context from the perspective of critical-structural pedagogy. It proposes an analysis of the intersection between colonialism, imperialism, and globalization. Subsequently, employing a structured qualitative examination through case analysis, the researchers delineate the fundamental characteristics of the research conducted at the former Officine Reggiane. Finally, the study discusses the emerging pedagogical themes and outlines potential avenues for development and intervention within the context
Smog and the Psyche: Chen Qiufan’s Reading of the Urban Anthropocene
No full textThe growing concern for environmental issues has fuelled the rise of climate fiction [cli-fi], a subgenre of science fiction dealing with climate change that has become increasingly popular in the last few decades. In China, significant examples can be found, among others, in Chen Qiufan’s works, which address these problems from different points of view. In his short story “Mai” 霾 [The Smog Society], the author explores the relationship between human beings and nature from an unconventional perspective, overturning the traditional conception of the relationship between the environment and the human mind. This article aims to analyse Chen Qiufan’s short story as an attempt to subvert the causal relationship between pollution and happiness, outlining his interpretation of the urban Anthropocene. The analysis will set out from what Glenn Albrecht has defined as “psychoterratic emotional concepts”, namely earth-related mental health conditions, to explore the author’s view of man-made climate change. In particular, it will explore the depiction of the climatic emergency in the Chinese urban context and its consequences on the protagonist’s psychology and emotions, as well as on urban social life
A Self-Learning Multi-Sensing Selection Process: Measuring Objects One by One
No full textThe paper presents a smart approach for a real time
inspection and selection of granular objects in continuous flow.
In the proposed approach, parallel channels are carved on a
planar substrate to contain object flow. Each channel operates
independently by processing and selecting grains one by one in
real-time using multiple sensing units. A 3D conformational
characterization of single objects is achieved by means of
simultaneous cross-combined optical and impedimetric sensing
technique. The sorting process is based on a 2 phase operative
methodology defined by software control: 1) a self-learning
step where the apparatus “learns” to identify objects by
inputting a-priori selected classes of objects so that decision
thresholds are adjusted accordingly; 2) an operative selection
process where objects are detected, classified using a decisional
algorithm and selected in real time by electromechanical
actuators. As working example, cereal grain selection is
presented
Adaptive Pervasive Advertisement: Scenarios and Strategies
No full textDigital screens increasingly pervade our everyday urban and social environments to serve a variety of purposes such as informing us about social and cultural events, traffic problems, or (in most of the cases) simply having the goal of displaying commercial advertisements. By exploiting pervasive computing and communication technologies, screens can “understand” who’s close to them and adapt accordingly the content shown on the screen, supplying to users a better service. In particular, advertisement companies can be lead to a much more targeted exploitation of the screen resource and, eventually, to higher revenues. In this paper, we firstly introduce the key concepts of adaptive pervasive advertisement, its potential scenarios of adoption and the design and implementation of a simple advertisement system. Then, we present and evaluate different strategies for composing the sequence of commercials to be broadcasted. Simulation studies demonstrate that an adaptive advertisement system, able to sense about people in the environment and of exploiting a context-sensitive strategy accordingly, offers a notable commercial advantage over traditional advertisement system, even when visitors demonstrate poor collaboration towards the system
BV-2 Microglial Cells Respond to Rotenone Toxic Insult by Modifying Pregnenolone, 5alpha-Dihydroprogesterone and Pregnanolone Level
No full textNeuroinflammation, whose distinctive sign is the activation of microglia, is supposed
to play a key role in the development and progression of neurodegenerative diseases. The aim of
this investigation was to determine levels of neurosteroids produced by resting and injured BV-2
microglial cells. BV-2 cells were exposed to increasing concentrations of rotenone to progressively
reduce their viability by increasing reactive oxygen species (ROS) production. BV-2 cell viability
was significantly reduced 24, 48 and 72 h after rotenone (50–1000 nM) exposure. Concomitantly,
rotenone (50–100 nM) determined a dose-independent augmentation of ROS production. Then,
BV-2 cells were exposed to a single, threshold dose of rotenone (75 nM) to evaluate the
overtime release of neurosteroids. In particular, pregnenolone, pregnenolone sulfate, progesterone,
5alpha-dihydroprogesterone (5-DHP), allopregnanolone, and pregnanolone, were quantified in the
culture medium by liquid chromatography with tandem mass spectrometry (LC-MS/MS) analysis.
BV-2 cells synthesized all the investigated neurosteroids and, after exposure to rotenone, 5DHP and
pregnanolone production was remarkably increased. In conclusion, we found that BV-2 cells not only
synthesize several neurosteroids, but further increase this production following oxidative damage.
Pregnanolone and 5alpha-DHP may play a role in modifying the progression of neuroinflammation in
neurodegenerative diseases
Human Microglia Synthesize Neurosteroids to Cope with Rotenone-Induced Oxidative Stress
No full textWe obtained evidence that mouse BV2 microglia synthesize neurosteroids dynamically to modify neurosteroid levels in response to oxidative damage caused by rotenone. Here, we evaluated whether neurosteroids could be produced and altered in response to rotenone by the human microglial clone 3 (HMC3) cell line. To this aim, HMC3 cultures were exposed to rotenone (100 nM) and neurosteroids were measured in the culture medium by liquid chromatography with tandem mass spectrometry. Microglia reactivity was evaluated by measuring interleukin 6 (IL-6) levels, whereas cell viability was monitored by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. After 24 h (h), rotenone increased IL-6 and reactive oxygen species levels by approximately +37% over the baseline, without affecting cell viability; however, microglia viability was significantly reduced at 48 h (p p < 0.05). Interestingly, treatment with exogenous allopregnanolone (1 nM) efficiently prevented the reduction in HMC3 cell viability. In conclusion, this is the first evidence that human microglia can produce allopregnanolone and that this neurosteroid is increasingly released in response to oxidative stress, to tentatively support the microglia’s survival
Novel Technique for Real Time Individual Object Sorting
No full textThe content of the present paper aims at seeking faster speed and lower cost methods for characterizing granular objects in general, and cereal grains in particular. The approach is based on simultaneous cross-combined optical and impedimetric sensing techniques in the MHz range, applied to flowing streams so as to determine real-time 3D morphological characterization of single objects. The main advantages of the proposed approach rely on the high discriminatory capacity of the object classes and on the high degree of parallelism, capable of processing large amounts of material on production lines. The use of integrated electronic systems also allows high operative speed, easy calibration and flexibility to the required classification features
MULTIPHYSIC FEM TOOL FOR CAPACITIVE DIFFERENTIAL PRESSURE SENSORS DESIGN
No full textIn this paper a multiphysic Fem model able to design capacitive pressure sensor is presented. The sensor is designed for aerodynamic applications and in particular to operate in the weak pressure field acting on a sail plan. The device is able to detect the differential pressure acting between the leeward and windward side of the sail. The sensing element of the device is a thin conductive diaphragm glue to a PCB structure deflecting under a differential pressure, able to operate in a +/- 250 Pa pressure field. Coupled electrical and mechanical finite element simulations have been performed in order to estimate the sensor behaviour. The Fem multiphysic model developed has been used to predict the behaviour of the sensing element, to achieve the required sensitivity, resolution, and to reduce the drift error due to viscoelastic behaviour of the diaphragm. Viscoelastic effects also heve been taken into account in the simulation process to evaluate the time dependent deformation of the membrane causing a drift of the signal at constant pressure. The Fem model is targeted to supply a powerful tool to design cheap, reliable and conformable pressure devices capable to provide differential pressure maps over full batten sails
