Istruzione e produzione nei Quaderni del carcere
2019
In questo scritto, verranno interrogati alcuni paragrafi dei Quaderni del carcere di Gramsci relativi alla questione dell’istruzione, mostrandone i nessi con paragrafi dedicati all’industrialismo fordista e alle trasformazioni economico-produttive dei primi decenni del Novecento. Verrà, così, evidenziata la presenza, nei Quaderni, di un isomorfismo lessicale tra discorso sulla scuola e discorso sulla produzione e sulle mutazioni antropologiche consustanziali all’affermazione del fordismo. Per farlo, ci si soffermerà, tra le altre cose, sulla figura della scuola unica/unitaria per la prima volta evocata nel Quaderno 1 e poi approfondita nei Quaderni 4 e 12.
Hierarchical cross-scale analysis identifies parallel ventral striatal networks coding for dynamic and stabilized olfactory reward predictions
2021
SUMMARYThe unbiased identification of brain circuits responsible for behavior and their local cellular computations is a challenge for neuroscience. We establish here a hierarchical cross-scale approach from behavioral modeling and fMRI in task-performing mice to cellular network dynamics to identify how reward predictions are represented in the forebrain upon olfactory conditioning. fMRI identified functional segregation in reward prediction and error computations among olfactory cortices and subcortical circuits. Among them, the olfactory tubercle contributed both to dynamic reward predictions and prediction error. In this region, cellular recordings revealed two parallel neuronal populat…
Short-term impact of a Western diet on the physiology of the peripheral olfactory system
2016
Current feeding behaviors contribute to the epidemic levels of obesity and diabetes observed in Europe and worldwide. Both the quantity and the quality of ingested food are incriminated. Together with other sensory modalities, olfaction is involved in the control of food intake. Olfactory cues can influence eating behaviors, yet the nutritional status and diet can also alter olfactory abilities. Patients with metabolic disorders present impaired olfactory sensitivity which could in turn worsen their eating behaviors.Here we examined the short-term impact of a Western diet enriched in fat and sugar (High Fat High Sugar, HFHS) on the anatomy and physiology of the olfactory epithelium of postn…
Enzymatic systems involved in peri-receptor events of olfaction in mammalian: evolutionary perspectives
2021
International audience; The olfactory epithelium is continuously exposed to exogenous chemicals, including compounds bearing odor activity. Organisms have developed multiple mechanisms for the protection of this epithelium, among which anti-microbial proteins, enzymes fighting the oxidative stress and xenobiotic metabolizing enzymes. Our approach consists in characterizing by immunohistochemistry and mass spectroscopy analysis the proteome of the nasal mucus in different mammals (currently including Harbour porpoise, Homo sapiens, Mus musculus, Oryctolagus cuniculus, Rattus norvegicus). These analyses reveal core some enzyme families in the different species investigated, including glutathi…
Factory Workers' Ordinary User Experiences: An Overlooked Perspective
2018
Experiences with technology often are described as exciting and outstanding, for instance, in relation to novel technologies at home or at work. In this article, we aim to complement this perspective by emphasizing people’s mundane and ordinary experiences with technology, that is, unremarkable experiences happening in the background of people’s attention. Based on our investigations of user experience in a semiconductor factory, we show how such ordinary experiences are substantial in workers’ everyday interactions with technology, which are mainly shaped by repetitive activities and routines. However, current conceptions of user experience seem to overlook those mundane experiences and ho…
Orosensory Perception of Dietary Lipids in Mammals
2008
Obesity constitutes a major public health problem for the twenty-first century, with its epidemic spread worldwide, particularly in children. The overconsumption of fatty foods greatly contributes to this phenomenon. Rodents and humans display a spontaneous preference for lipid-rich foods. However, the molecular mechanisms underlying this pattern of eating behaviour in mammals remain unclear. The orosensory perception of dietary lipids was long thought to involve only textural and olfactory cues. Recent findings challenge this limited viewpoint, strongly suggesting that the sense of taste also plays a significant role in dietary lipid perception and might therefore be involved in the prefer…
Olfactory and cortical projections to bulbar and hippocampal adult-born neurons
2015
New neurons are continually generated in the subependymal layer of the lateral ventricles and the subgranular zone of dentate gyrus during adulthood. In the subventricular zone, neuroblasts migrate a long distance to the olfactory bulb where they differentiate into granule or periglomerular interneurons. In the hippocampus, neuroblasts migrate a short distance from the subgranular zone to the granule cell layer of the dentate gyrus to become granule neurons. In addition to the short-distance inputs, bulbar interneurons receive long-distance centrifugal afferents from olfactory-recipient structures. Similarly, dentate granule cells receive differential inputs from the medial and lateral ento…
Linking the residential satisfaction to landscape metrics: a tool for urban planning?
2010
International audience; This paper examines the links between residential satisfaction of periurban households and landscape structure of their spatial neighbourhood. Satisfaction of people was measured using a survey while landscape composition was quantified from remotely sensed data. Results are simulated in order to identify areas of satisfaction.
La contabilidad de costes a finales del s. XIX: el caso de la empresa española Trenor y Cía. (1838-1926)
2006
El objetivo principal de este estudio es aportar evidencia empírica sobre la evolución de los sistemas de costes, y el papel de la información contable como instrumento esencial en la gestión y evolución de las empresas, para lo que hemos investigado el caso de la sociedad colectiva Trenor y Cía., una de las empresas más relevantes de la economía valenciana del siglo XIX, por su contribución al desarrollo agrícola e industrial. Aunque inicialmente se estableció en una fábrica de hilatura de seda y se dedicó a la importación y exportación de productos agrarios, exportación de pasas sobre todo, y a las operaciones de banca, en las últimas décadas del siglo XIX comenzó la producción de sacos, …
Rīgas autobusu fabrikas (RAF) ražoto modeļu veidi un pielietojums (1951.-1998.)
2021
Bakalaura darbs Rīgas autobusu fabrikas (RAF) Ražoto modeļu veidi un pielietojums (1951. - 1998.). Darba mērķis ir ir izpētīt rūpnīcas ražotos modeļus, analizējot to pielietojumu, tādējādi raksturojot PSRS autobūves pamatprincipus, vismaz tik lielā mērā, cik to var secināt no RAF produkcijas izpētes. Ka arī aprakstīt RAF rūpnīcas vēsturi RAF bija pirmais, kā arī populārākais autobusu un mikroautobusu ražotājs PSRS, radot piemēru un pamatu tālākai auto izstrādei visā valstī, sniedzot salīdzinoši atšķirīgus piemērus PSRS autobūves pamatnostādņu izstrādē. RAF ražotie modeļi sniedza materiāli tehnisko nodrošinājumu valsts funkciju izpildei, valsts policejiskās, kā arī medicīnas aprūpes struktūr…
