description: Questo lavoro prende spunto da alcune fotografie realizzate in Val Polcevera (Liguria, Italia) nel settembre del 1951 da Emilio Sereni (1907-1977), studioso il cui contributo alla fondazione degli studi storici sul paesaggio in Italia è ben noto. Nell’interpretazione, fondamentalmente “continuista”, di Sereni le immagini dovevano documentare una tipologia paesaggistica (il “marrelo”) riconducibile a tecniche antiche. Oggi, alla luce di più recenti studi, queste immagini assumono nuovo ruolo una volta inserite in una più vasta rete di fonti (iconografiche, testuali e di terreno). I risultati preliminari di questa ricerca mostrano infatti come una micro-analisi storico-geografica che ha inizio dall’individuazione dei siti fotografati possa meglio documentare i processi ambientali che hanno attraversato l’ecologia dei paesaggi rurali individuati da Sereni stesso e le loro risorse. Tutto ciò al fine di orientare le azioni di pianificazione ambientale e di valorizzazione delle produzioni locali in un contesto che è attualmente al centro di diversi progetti di rigenerazione urbanistica.

description: Background:Dystonia is a movement disorder characterized by involuntary muscle contractions that cause twisting movements and abnormal postures. Primary dystonia is the most common form and is thought to be a multifactorial condition in which one or more genes combine with environmental factors to reach disease. Methods:We reviewed controlled studies on possible environmental risk factors for primary early‐ and late‐onset dystonia. ResultsEnvironmental factors associated with primary early‐onset dystonia are poorly understood. Early childhood illnesses have been reported to be more frequent in patients with DYT1 dystonia than in subjects carrying the DYT1 mutation that did not manifest dystonia, thus raising the possibility that such exposures precipitate dystonia among DYT1 carriers. Conversely, several environmental factors have been associated with primary adult‐onset focal dystonias compared to control subjects. Namely, eye diseases, sore throat, idiopathic scoliosis, and repetitive upper limb motor action seem to be associated with blepharospasm (BSP), laryngeal dystonia (LD), cervical dystonia (CD), and upper limb dystonia, respectively. In addition, an inverse association between coffee drinking and BSP has been observed in both case‐unrelated control and family‐based case‐control studies. Additional evidence supporting a causal link with different forms of primary late‐onset dystonia is only available for diseases of the anterior segment of the eye, writing activity, and coffee intake. ConclusionThere is reasonable epidemiological evidence that some environmental factors are risk‐modifying factors for specific forms of primary adult‐onset focal dystonia.

description: Il tema della transizione energetica è diventato da tempo un elemento centrale della politica europea, perché è ormai chiaro che progresso e tutela dell'ambiente sono fortemente correlati e, in condizioni di scarsità di risorse energetiche, lo sviluppo deve necessariamente essere sostenibile. Affinché questi obiettivi siano raggiungibili, sono stati introdotti strumenti di sostegno alla transizione pensati per le comunità locali. L'applicazione di questi strumenti è finalizzata ad assicurare la riconversione di siti produttivi obsoleti, a garantire l'accesso all'energia, a creare opportunità di lavoro e a fornire formazione professionale. Tra questi strumenti, le comunità energetiche sono forme di produzione e autoconsumo di energia realizzate da una coalizione di utenti che producono, consumano e gestiscono energia attraverso impianti energetici di piccola taglia. L'Italia è già da un decennio destinataria di interventi finalizzati alla coesione territoriale, e in Sicilia la sperimentazione delle comunità energetiche potrebbe avere un vantaggio competitivo grazie alla sua posizione geografica. La nostra ricerca si è posta l'obiettivo di osservare un entroterra siciliano che, plasmato nel tempo da eventi naturali e azioni umane, potrebbe beneficiare dell'applicazione delle comunità energetiche nelle aree rurali. Poiché la nostra osservazione è avvenuta in concomitanza con l'adozione di azioni normative nell'ambito della Politica di Transizione dell'Unione Europea, riteniamo che questa analisi possa introdurci in una nuova prospettiva in cui è possibile inquadrare alcune parti di territori marginali, come la Valle del Belìce, anch'essa colpita da eventi distruttivi, costretta ad affrontare scelte legate alla sopravvivenza socio-economica delle sue comunità. Infine, proponiamo la possibilità, secondo la Strategia Nazionale per le Aree Interne (SNAI) come politica per lo sviluppo locale, di entrare in un altro campo di intervento, quello della ricostruzione post-terremoto in Sicilia. Le comunità e i territori dovrebbero essere maggiormente coinvolti in un tavolo di partenariato per scrivere una strategia d'area e scegliere le migliori localizzazioni sul territorio, per una volta non a scapito delle comunità locali ma piuttosto a loro favore, in totale connessione con gli obiettivi delle comunità energetiche.

description: Il film geografico sta progressivamente affermandosi come metodo di ricerca e restituzione incarnato, relazionale, più-che-visuale e più-che- narrativo, utile ad abbracciare le sfide della geografia contemporanea. Tuttavia restano ancora numerose questioni aperte e irrisolte, tra cui quella, apparentemente banale, ma oggi più che mai urgente, di delineare con più chiarezza in che modo il film geografico possa oggi differenziarsi da altre tipologie di audiovisivi. L’obiettivo di questa riflessione, che si pone in continuità con la sintesi sui primi sviluppi della filmic geography presentata in un precedente articolo, è quello di contribuire a fare avanzare il dibattito in corso sull’inserimento della ricerca filmica nel contesto accademico, negli ultimi anni arricchitosi anche grazie ad esperienze di film geografici italiani realizzati nell’ambito di tesi magistrali e dottorali, riflettendo in particolare intorno a tre nodi chiave: la definizione di film geografico, le possibilità di indagine geografica scaturite dall’attrezzatura cinematografica e la relazione tra film geografico e multimedialità.

description: We present simulations of the multi-phase interstellar medium (ISM) at solar neighbourhood conditions including thermal and non-thermal ISM processes, star cluster formation, and feedback from massive stars: stellar winds, hydrogen ionising radiation computed with the novel TreeRay radiative transfer method, supernovae (SN), and the injection of cosmic rays (CR). N-body dynamics is computed with a 4th-order Hermite integrator. We systematically investigate the impact of stellar feedback on the self-gravitating ISM with magnetic fields, CR advection and diffusion and non-equilibrium chemical evolution. SN-only feedback results in strongly clustered star formation with very high star cluster masses, a bi-modal distribution of the ambient SN densities, and low volume-filling factors (VFF) of warm gas, typically inconsistent with local conditions. Early radiative feedback prevents an initial starburst, reduces star cluster masses and outflow rates. Furthermore, star formation rate surface densities of $Σ_{\dot{M}_\star} = 1.4-5.9 \times 10^{-3}$ $\mathrm{M}_\odot\,\mathrm{yr}^{-1}\,\mathrm{kpc}^{-2}$, VFF$_\mathrm{warm} = 60-80$ per cent as well as thermal, kinetic, magnetic, and cosmic ray energy densities of the model including all feedback mechanisms agree well with observational constraints. On the short, 100 Myr, timescales investigated here, CRs only have a moderate impact on star formation and the multi-phase gas structure and result in cooler outflows, if present. Our models indicate that at low gas surface densities SN-only feedback only captures some characteristics of the star-forming ISM and outflows/inflows relevant for regulating star formation. Instead, star formation is regulated on star cluster scales by radiation and winds from massive stars in clusters, whose peak masses agree with solar neighbourhood estimates.

description: Immunity is hypothesized to share limited resources with other physiological functions and may mediate life history trade-offs, for example between reproduction and survival. However, vertebrate immune defense is a complex system that consists of three components. To date, no study has assessed all of these components for the same animal model and within a given situation. Previous studies have determined that the acquired immunity of common eiders (Somateria mollissima) is suppressed during incubation. The present paper aims to assess the innate immune response in fasting eiders in relation to their initial body condition. Innate immunity was assessed by measuring plasma nitric oxide (NO) levels, prior to and after injection of lipopolysaccharides (LPS), a method which is easily applicable to many wild animals. Body condition index and corticosterone levels were subsequently determined as indicators of body condition and stress level prior to LPS injection. The innate immune response in eiders did not vary significantly throughout the incubation period. The innate immune response of eiders did not vary significantly in relation to their initial body condition but decreased significantly when corticosterone levels increased. However, NO levels after LPS injection were significantly and positively related to initial body condition, while there was a significant negative relationship with plasma corticosterone levels. Our study suggests that female eiders preserve an effective innate immune response during incubation and this response might be partially determined by the initial body condition.

description: We study the 2k-th power moment of Dirichlet L-functions L(s,χ) at the centre of the critical strip (s=1/2), where the average is over all primitive characters χ(mod q). We extend to this case the hybrid Euler-Hadamard product results of Gonek, Hughes & Keating for the Riemann zeta function. This allows us to recover conjectures for the moments based on random matrix models, incorporating the arithmetical terms in a natural way.

description: Background:: Essential tremor is characterized by several hyperkinetic movements, including arm and head tremors. We report another movement of the head in patients with essential tremor, which we term the “head snap.” This was observed as a jerking motion of the head in some patients while they performed the finger-nose-finger maneuver. Methods:: We compared the prevalence of the head snap in essential tremor patients vs. Parkinson’s disease patients. We also assessed the clinical correlates of the head snap. Results:: Ten (20%) of 50 essential tremor patients exhibited a head snap of any severity (rating ≥0.5) vs. 0 of 50 Parkinson’s disease patients (p = 0.001). Patients with head snap had more severe arm tremor on Archimedes spiral drawings (p = 0.019) and were more likely to have head tremor (p = 0.03) than those without it. Conclusions: This sign could be a useful aid in the clinical diagnosis of tremor.

description: Analyzing a huge amount of malware is a major burden for security analysts. Since emerging malware is often a variant of existing malware, automatically classifying malware into known families greatly reduces a part of their burden. Image-based malware classification with deep learning is an attractive approach for its simplicity, versatility, and affinity with the latest technologies. However, the impact of differences in deep learning models and the degree of transfer learning on the classification accuracy of malware variants has not been fully studied. In this paper, we conducted an exhaustive survey of deep learning models using 24 ImageNet pre-trained models and five fine-tuning parameters, totaling 120 combinations, on two platforms. As a result, we found that the highest classification accuracy was obtained by fine-tuning one of the latest deep learning models with a relatively low degree of transfer learning, and we achieved the highest classification accuracy ever in cross-validation on the Malimg and Drebin datasets. We also confirmed that this trend holds true for the recent malware variants using the VirusTotal 2020 Windows and Android datasets. The experimental results suggest that it is effective to periodically explore optimal deep learning models with the latest models and malware datasets by gradually reducing the degree of transfer learning from half.

description: Questo lavoro ha lo scopo di analizzare una preziosa fonte storica, quale il catasto “onciario” o “carolino”, per lo studio della demografia e della proprietà fondiaria delle università del Regno di Napoli a metà Settecento. Si è considerato come caso di studio quello di una piccola università rurale dell’antica provincia di Terra di Lavoro. A una prima fase di lettura ed interpretazione del testo, è seguita l’estrazione e l’organizzazione,mediante strumenti informatici, dei dati in esso contenuti, con la loro analisi e la conseguente produzione di grafici e tabelle comparative. Questo approccio ha consentito di caratterizzare lo studio della demografia e delle condizioni socio-economiche della popolazione, evidenziando le strutture familiari e la loro composizione, le proprietà e i relativi carichi fiscali. Nel caso di Massa Inferiore questo studio evidenzia come l’onciario, che nelle intenzioni doveva distribuire in modo equo le imposte in rapporto al patrimonio posseduto, secondo una visione più moderna ed efficiente del regime di tassazione, nel generale clima riformista del tempo, in realtà, sia una riforma non compiutamente realizzata, perpetuando antichi privilegi e pesando ancora una volta in gran parte sulle classi più povere.

description: In the planar limit, in the deconfined phase, the Euclidean Dirac operator has a spectral gap around zero. We show that functions of eigenvalues close to the spectral edge, which are independent of common rescalings and shifts gauge configuration by gauge configuration, have distributions described by a Gaussian Hermitian matrix model. However, combinations of eigenvalues that are scale and shift invariant only on the average, do not match this matrix model.

description: While supervised learning is widely used for perception modules in conventional autonomous driving solutions, scalability is hindered by the huge amount of data labeling needed. In contrast, while end-to-end architectures do not require labeled data and are potentially more scalable, interpretability is sacrificed. We introduce a novel architecture that is trained in a fully self-supervised fashion for simultaneous multi-step prediction of space-time cost map and road dynamics. Our solution replaces the manually designed cost function for motion planning with a learned high dimensional cost map that is naturally interpretable and allows diverse contextual information to be integrated without manual data labeling. Experiments on real world driving data show that our solution leads to lower number of collisions and road violations in long planning horizons in comparison to baselines, demonstrating the feasibility of fully self-supervised prediction without sacrificing either scalability or interpretability.

description: Background: A body of literature is emerging regarding gait/balance impairments observed in essential tremor (ET) patients. Although impairment is generally mild, the full extent of the spectrum remains undefined. We present four ET cases with more severe gait/balance impairment. Methods: A battery of subjective and objective gait/balance assessments was performed: the Activities‐specific Balance Confidence Scale, the Berg Balance Scale, and the Tinetti Performance Oriented Mobility Assessment (POMA). Tandem missteps during 10 steps were counted. Quantitative gait testing was performed (GAITRite) to quantify gait speed, dynamic balance, gait symmetry, and gait variability. Results: Two patients were middle‐aged (38 and 52 years) and two were older (70 and 79 years). All had longstanding classic ET (duration 22–60 years). The mean POMA score was 21.5, which is indicative of moderate fall risk. On average, there were five missteps during tandem gait, which was higher than observed in substantially older ET cases (age 86.0±4.6 years), and four times higher than seen in ET patients of comparable age. On quantitative gait analysis, patients demonstrated significant balance impairment. Discussion: We present a sample of ET patients with a level of gait difficulty that would not be characterized as mild. The existence of such cases raises a number of questions, one of which is how impaired can gait be in ET?

description: The standard Bell inequality experiments test for violation of local realism by repeatedly making local measurements on individual copies of an entangled quantum state. Here we investigate the possibility of increasing the violation of a Bell inequality by making collective measurements. We show that nonlocality of bipartite pure entangled states, quantified by their maximal violation of the Bell-Clauser-Horne inequality, can always be enhanced by collective measurements, even without communication between the parties. For mixed states we also show that collective measurements can increase the violation of Bell inequalities, although numerical evidence suggests that the phenomenon is not common as it is for pure states.

description: Background: Orthostatic tremor (OT) is a high‐frequency tremor (13–18 Hz) present in the legs when standing. Underlying disease is found in one‐third of OT patients. Case report: We describe an 86‐year‐old man with progressive shaking of the legs while standing, which disappears immediately after sitting down or while walking. Polymyography confirmed a tremor of the legs (10–11 Hz) while standing. Magnetic resonance imaging (MRI) and neurologic examination showed no underlying disease. Discussion: Primary OT can appear at a lower frequency of 10–11 Hz.

Chromatin immunoprecipitations recified that these HMGA1 interactions take place in vivo and defined the temporal pattern og its bibnding to virus DNA during the course of an infection.ICP4, the major HSV-1 regulatory protein, was also found to bind all IE regulatory sequences, both in vitro and in vivo and its in vitro DNA binding was enhonced by HMGA1. Trasient expression experiments demonstrated that HMGA1 alters IE gene expression in vivo both in the absence or presence of viral proteins.These effects were both promoter-and viral protein-specific. These findings suggest that HMGA1 can affect IE gene expression, and the progress of a lytic HSV-1 infection, in vivo

description: Certain approximate solutions of the continuum Schwinger-Dyson Equations (SDEs) predict chiral symmetry breaking in the 3d Thirring model when the number of fermion flavors N_f<4.32 whereas others predict symmetry breaking for all N_f. Our results from Monte Carlo simulations with N_f=6, predict a second order chiral phase transition. The critical coupling in this case corresponds to an ultra-violet fixed point of the renormalization group defining a non-trivial continuum limit. Further, our numerical simulations provide an estimate for the critical number of fermion flavors, N_fc \approx 6.5.

description: We present a new necessary condition for similarity of indefinite Sturm-Liouville operators to self-adjoint operators. This condition is formulated in terms of Weyl-Titchmarsh $m$-functions. Also we obtain necessary conditions for regularity of the critical points 0 and $\infty$ of $J$-nonnegative Sturm-Liouville operators. Using this result, we construct several examples of operators with the singular critical point zero. In particular, it is shown that 0 is a singular critical point of the operator $-\frac{(\sgn x)}{(3|x|+1)^{-4/3}} \frac{d^2}{dx^2}$ acting in the Hilbert space $L^2(\R, (3|x|+1)^{-4/3}dx)$ and therefore this operator is not similar to a self-adjoint one. Also we construct a J-nonnegative Sturm-Liouville operator of type $(\sgn x)(-d^2/dx^2+q(x))$ with the same properties.

description: AOSAT is a python package for the analysis of single-conjugate adaptive optics (SCAO) simulation results. Python is widely used in the astronomical community these days, and AOSAT may be used stand-alone, integrated into a simulation environment, or can easily be extended according to a user's needs. Standalone operation requires the user to provide the residual wavefront frames provided by the SCAO simulation package used, the aperture mask (pupil) used for the simulation, and a custom setup file describing the simulation/analysis configuration. In its standard form, AOSAT's "tearsheet" functionality will then run all standard analyzers, providing an informative plot collection on properties such as the point-spread function (PSF) and its quality, residual tip-tilt, the impact of pupil fragmentation, residual optical aberration modes both static and dynamic, the expected high-contrast performance of suitable instrumentation with and without coronagraphs, and the power spectral density of residual wavefront errors. AOSAT fills the gap between the simple numerical outputs provided by most simulation packages, and the full-scale deployment of instrument simulators and data reduction suites operating on SCAO residual wavefronts. It enables instrument designers and end-users to quickly judge the impact of design or configuration decisions on the final performance of down-stream instrumentation.

description: A novel modular high-resolution charged-particle tracking detector design using $250μm$ diameter, round, scintillating fibers and SiPM arrays for readout is presented. The fiber modules consist of 8 layers of 128 fibers, mechanically sta bilized by a carbon fiber / Rohacell foam structure. A prototype using scintillating fibers with a diameter of $300μm$ and two typ es of silicon photomultipliers has been tested in a $10GeV$ proton beam in late October 2006 at the T9 PS-beamline, CERN. We present the measured spatial resolu tion, efficiency and signal-over-noise for this setup. The advantage of this tra cker concept is a compact and modular design with low material budget and only little or no cooling requirements depending on the quality of the silicon photomultiplieres.

description: Background: A 37‐year‐old female with a hyperkinetic movement disorder due to chorea‐acanthocytosis developed severe painful degenerative arthritis of her left knee as a consequence of repetitive involuntary flexion and extension dystonic and ballistic movements. Case Report: Despite profound limitation in her mobility a total knee replacement was successfully undertaken. Discussion: The case emphasizes that patients with progressive neurodegenerative disorders may derive relief or resolution of pain by joint replacement even if mobility does not improve following surgery. A multidisciplinary approach to care is essential.

Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections (PANDAS): An Evolving Concept

description: Pediatric autoimmune neuropsychiatric disorders associated with streptococcus infections (PANDAS) originated from the observational work of Swedo and collaborators, who formalized their definition in 1998 in a set of operational criteria. The application of these criteria, which focuses on tics and obsessive-compulsive symptoms as core symptoms, has encountered difficulties, eventually leading to a high rate of misdiagnosis. In particular, the core feature represented by the association between newly diagnosed infections and neuropsychiatric symptom relapses in youths with this diagnosis could not be demonstrated by longitudinal studies. Exploratory studies aiming to identify clinical or cognitive features that could discriminate PANDAS from other pediatric obsessive-compulsive and tic disorders present methodological limitations, and therefore are not conclusive. Other behavioral features, in addition to obsessive-compulsive symptoms and tics, have been included in pediatric acute-onset neuropsychiatric syndromes (PANS) and childhood acute neuropsychiatric syndromes (CANS), two new concepts recently proposed in order to define a much broader clinical spectrum encompassing etiologically diverse entities. Given the uncertainties on the clinical definition of PANDAS, it is not surprising that evidence in support of a post-infectious, immune-mediated pathophysiology is also insufficient. Anti-dopamine receptor antibodies might be relevant to both Sydenham’s chorea (SC)—the prototypical post-streptococcal neuropsychiatric disorder—and some rare forms of encephalitis targeting the basal ganglia specifically, but studies exploring their association with children fulfilling Swedo’s criteria for PANDAS have been inconclusive. Moreover, we lack evidence in favor of the efficacy of antibiotic prophylaxis or tonsillectomy in patients fulfilling Swedo’s criteria for PANDAS, whereas a response to immune-mediated treatments like intravenous immunoglobulins has been documented by one study, but needs replication in larger trials. Overall, the available evidence does not convincingly support the concept that PANDAS are a well-defined, isolated clinical entity subdued by definite pathophysiological mechanisms; larger, prospective studies are necessary to reshape the nosography and disease mechanisms of post-streptococcal acute neuropsychiatric disorders other than SC. Research is also under way to shed further light on a possible relationship between streptococcal infections, other biological and psychosocial stressors, and the complex pathobiology of chronic tic disorders.

Space Ordering Theory in Humanistic Geography: A New Reading of the Biblical Exodus Route and Har Karkom Archaeological Ruins (Negev Desert)
Creators: name: Crosilla, Fabio
Publisher: name: Semestrale di studi e ricerche di geografia
Year: 2023

description: L’articolo propone una procedura innovativa, basata sulla teoria dell’ordinamento spaziale in geografia umanistica [H. Lefebvre (1991), E.W. Soja (1996)], per una lettura del percorso dell’Esodo biblico e dell’ubicazione del Monte Sinai. Il deserto del Sinai è caratterizzato da severe condizioni ambientali dove, oggigiorno, è ancora possibile trovare resti archeologici di insediamenti nomadici che spaziano dal periodo Paleolitico al periodo della conquista Islamica. La gran parte degli insediamenti ubicati nella zona di Har Karkom (deserto del Negev) sono stati studiati dal gruppo di ricerca del prof. Emmanuel Anati nel corso di quarant’ anni di attività e identificati come una delle possibili ubicazioni del Monte Sinai (ad es. Anati 2018). In base alla geografia umanistica, il paesaggio desertico e i resti archeologici della Penisola del Sinai possono essere studiati e interpretati attraverso la Teoria del Primo Spazio. Il Secondo Spazio si pone l’obiettivo di investigare l’origine e classificare l’età e lo scopo di tali resti e dei relativi insediamenti che garantirono la sopravvivenza delle popolazioni e delle greggi al seguito durante le migrazioni stagionali della pastorizia o durante i frequenti trasferimenti fra le due terre confinanti la Penisola del Sinai: l’Egitto e la Terra di Canaan. In base alla ricostruzione storica dei resti archeologici, il Terzo Spazio può essere invece considerato come lo spazio della “stratificazione culturale e della fondazione della memoria individuale e sociale” (Lando e Voltolina 2005). A tal proposito, ciò può essere posto in relazione con la composizione durante il Periodo Ellenistico (Barbaglia 2017) di una “storia sacra”, il cosiddetto Esodo biblico di precedenti popolazioni dal Delta del Nilo alla Terra di Canaan. Dopo una breve introduzione in merito alla proposta dell’esodo Biblico di S. Barbaglia (2017), l’articolo approfondisce le caratteristiche della Teoria dell’Ordinamento Spaziale introdotta in geografia umanistica da H. Lefebvre (1991) e E.W. Soja (1996). Infine vengono analizzate le applicazioni di questa teoria per una proposta di ricostruzione del percorso dell’esodo Biblico.

Cooperative industrial relations in the B.C. solid wood products sector
Creators: name: Murphy, David Gerald
Publisher: name: University of British Columbia
Year: 2011

description: The initiation of more cooperative relations between the companies and the union (IWA-Canada) in the B.C. solid wood products sector, on the one hand, and between these two and the federal government, on the other hand, appears to signal an end to the "exceptionalism" which precluded the establishment of "corporatism" in Canadian industry. As the sector has been under tremendous pressure from various structural and technological changes, as well as interest groups both inside the forest industry and outside of it, does this change in industrial relations provide a model for the future forest industry or is it an impediment to change, as many critics contend. This thesis will explore the formation of "Fordist" industrial relations in the sector and the present "crisis" in Fordism as it relates to the sector, in order to understand the factors impelling cooperative industrial relations, and how these factors will affect these relations in the future. As these factors are undermining Fordism, they might also undermine the tentative, defensive cooperation between the three parties. In place of this exclusive policy-making regime a new, broad-based, decentralized, and more democratically controlled forest sector might emerge which will encourage cooperative industrial relations, but without the dominance of the old Fordist structures. The ensuing changes will widely affect economic, political and social relations throughout the province.
