Artivismo antimilitarista: l’esperienza del Movimento No Dal Molin a Vicenza
No full textL\u27esperienza del Movimento No Dal Molin nasce a Vicenza nel 2006 contro la costruzione di una nuova base militare Usa nell’ex aeroporto Dal Molin. Da allora il Presidio Permanente No Dal Molin diventa la casa comune di diverse realtà antimilitariste e lo spazio della creatività del movimento.
L\u27arte ha un ruolo fondativo di tale attivismo politico, in diverse forme riconducibili alla sfera della public art. Mentre le basi militari vicentine imitano l\u27arte di Andrea Palladio, infatti, il Movimento No Dal Molin attraversa la città con performance e produzioni artistiche partecipative.
L’articolo intende approfondire alcune delle forme artistiche proposte dal 2006 al 2014 e indagarne l’attuale eredità. Tra queste: le azioni di Teatro invisibile e teatro di strada che le donne del movimento hanno usato per stimolare inizialmente il dibattito pubblico sulla base militare; i contributi di artisti locali, come l’azione rivolta all’Unesco The Burning Cemetery, di Alberto Peruffo; infine Silent Play, un percorso audioguidato coordinato da Carlo Presotto e scritto collettivamente: nella fase di costruzione della base, ripercorreva luoghi ed eventi simbolo del movimento.The No Dal Molin Movement was born in Vicenza in 2006 against the construction of a new US military base in the former Dal Molin airport. Since then, the No Dal Molin Permanent Presidium has become the common home of various anti-militarist realities and the space for the movement\u27s creativity. Art has a founding role in this political activism, in various forms attributable to the sphere of public art. While the Vicenza military bases imitate the art of Andrea Palladio, in fact, the No Dal Molin Movement crosses the city with participatory artistic performances and productions.
The article intends to deepen some of the artistic forms proposed from 2006 to 2014 and investigate their current legacy. Among these: the actions of invisible theater and street theater that the women of the movement used to initially stimulate the public debate on the basis; the contributions of local artists, such as the action addressed to Unesco The Burning Cemetery, by Alberto Peruffo; Silent Play, an audio-guided tour coordinated by Carlo Presotto and written collectively which, during the construction phase of the base, retraced the places and events that symbolize the movement
The claustrum of the bottlenose dolphin Tursiops truncatus (Montagu 1821)
No full textThe mammalian claustrum is involved in processing sensory information from the environment. The claustrum is reciprocally connected to the visual cortex and these projections, at least in carnivores, display a clear retinotopic distribution. The visual cortex of dolphins occupies a position strikingly different from that of land mammals. Whether the reshaping of the functional areas of the cortex of cetaceans involves also modifications of the claustral projections remains hitherto unanswered. The present topographic and immunohistochemical study is based on the brains of eight bottlenose dolphins and a wide array of antisera against: calcium-binding proteins (CBPs) parvalbumin (PV), calretinin (CR), and calbindin (CB); somatostatin (SOM); neuropeptide Y (NPY); and the potential claustral marker Gng2. Our observations confirmed the general topography of the mammalian claustrum also in the bottlenose dolphin, although (a) the reduction of the piriform lobe modifies the ventral relationships of the claustrum with the cortex, and (b) the rotation of the telencephalon along the transverse axis, accompanied by the reduction of the antero-posterior length of the brain, apparently moves the claustrum more rostrally. We observed a strong presence of CR-immunoreactive (-ir) neurons and fibers, a diffuse but weak expression of CB-ir elements and virtually no PV immunostaining. This latter finding agrees with studies that report that PV-ir elements are rare in the visual cortex of the same species. NPY- and somatostatin-containing neurons were evident, while the potential claustral markers Gng2 was not identified in the sections, but no explanation for its absence is currently available. Although no data are available on the projections to and from the claustrum in cetaceans, our results suggest that its neurochemical organization is compatible with the presence of noteworthy cortical inputs and outputs and a persistent role in the general processing of the relative information. © 2014 Cozzi, Roncon, Granato, Giurisato, Castagna, Peruffo, Panin, Ballarin, Montelli and Pirone
Preparative isoelectric focusing of reduced wheat gluten proteins
No full textProteins extracted from gluten of the bread wheat cultivar Fiorello 2 in the presence of 2-mercaptoethanol or dithiothreitol were separated by isoelectric focusing in a free solution in a pH 3–10 gradient containing 50% v/v 1-propanol or urea. The collected fractions were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis in 10% gels (high and medium molecular weight glutenin subunits) and 16% gels (low molecular weight gliadins). The isoelectric focusing pattern of gluten polypeptides in 50% v/v 1-propanol was comparable to that obtained on two-dimensional gel electrophoresis, based on isoelectric focusing and polyacrylamide gel electrophoresis or nonequilibrium pH gradient electrophoresis and polyacrylamide gel electrophoresis. A similar isoelectric focusing pattern was also observed when 3M urea was used as solvent. New gluten polypeptides, similar in mobility to the high molecular weight subunits of glutenin were detected at acidic pH
Le strategie di Turnaround nell'era digitale: modelli di analisi e sviluppo
No full textLa rivoluzione digitale è un processo che in maniera crescente sta travolgendo tutte le industrie modificandone i tradizionali tratti distintivi e rendendo i confini nazionali sempre meno rilevanti. Rappresenta una spinta alla trasformazione e al turnaround delle imprese che stanno soffrendo una fase di declino organizzativo, ma anche un’opportunità di crescita e di sviluppo per il sistema Paese. Il lavoro analizza i principali trend osservati e le maggiori sfide emergenti dalla trasformazione digitale a livello globale e con specifico riferimento alle piccole e medie imprese. Il volume si sviluppa intorno all'analisi dei modelli e delle strategie di turnaround, che rappresentano oggigiorno la sfida più importante per tutte quelle imprese che stanno attraversando una fase di difficoltà organizzativa e che vedono nella rivoluzione digitale, da un lato la possibile causa della situazione di declino organizzativo, e dall’altro la “soluzione” strategica per riportare l’azienda nelle condizioni di creazione del valore. La letteratura nazionale e internazionale viene sistematizzata nell’ambito di un quadro di analisi che affonda le sue radici nel lavoro seminale di Pearce e Robbins del 1993, facendo emergere in tal modo i principali modelli teorici e le più rilevanti evidenze empiriche. Tale piano di analisi, basato su quattro dimensioni rilevanti - antecedenti, fattori abilitanti, processo e performance – viene altresì sviluppato per analizzare le strategie di turnaround delle piccole e medie imprese. La trattazione approfondisce lo sviluppo di un framework analitico per la formulazione e l’implementazione delle strategie di turnaround nell’era digitale. Il modello offre l’opportunità di analizzare attraverso la lente interpretativa delle strategie di turnaround, il complesso di scelte ed azioni che le imprese sono chiamate a porre in essere in questa fase per affrontare le sfide della rivoluzione digitale, con un focus specifico sulla piccola e media impresa. Lo studio è arricchito con l’integrazione di casi ed esperienze emerse a livello globale e nazionale. In ultimo, nella sezione conclusiva vengono evidenziati i principali contributi teorici e alcune delle domande di ricerca ancora inesplorate
Art in Business Strategies: the case of Peruffo Jewelry
No full textreservedIl presente elaborato si pone l'obiettivo di indagare il rapporto che intercorre tra arte e impresa dal punto di vista di quest'ultima. Una prima analisi teorica introduce le diverse modalità in cui due
mondi, apparentemente distanti tra loro, si integrano e generano valore aggiunto sia all’interno dell’organizzazione sia verso l’esterno, apportando benefici organizzativi ed economici. La seconda parte si fa via via più specifica concentrandosi sulle aziende appartenenti al settore orafo portando una serie di esempi che evidenziano i diversi modi in cui arte e imprese si intrecciano tra di loro. L’analisi si conclude attraverso lo studio di un caso aziendale, Peruffo Jewelry, che avrà l’obiettivo di dimostrare come l’arte introdotta nelle strategie aziendali possa costituire un vantaggio per l’impresa.This paper aims to investigate the relationship between art and business from the point of view of the latter. A first theoretical analysis introduces the different ways in which two worlds, apparently distant from each other, integrate and generate added value both within the organization and externally, bringing organizational and economic benefits. The second part becomes more specific by focusing on companies belonging to the goldsmith sector, bringing a series of examples that highlight the different ways in which art and business are intertwined. The analysis concludes with a study of a business case, Peruffo Jewelry, which will aim to demonstrate how art introduced in business strategies can constitute an advantage for the company
Knowledge Spillovers from FDI: A Critical Review from the International Business Perspective
No full textThis paper reviews and organizes the theoretical and empirical research on foreign direct investment (FDI) knowledge spillovers from the international business perspective. In doing so, it develops a framework for the analysis of this phenomenon. The suggested FDI knowledge spillover framework integrates both the macro-level (country, industry, institutions) and micro-level (multinational firm, headquarters, subsidiary, local firms) antecedents of spillovers with their consequences, and proposes to analyse spillovers along three main attributes that characterize their occurrence, i.e. their magnitude, scope and speed
On the complexity issue from neuroscience to economics: scatter-based ranks’ estimation
No full textWe set up the notion of neuron morphometric complexity, with the goal of quantify the degree of similarity vs. dissimilarity (i.e. homogeneity vs. heterogeneity) of a set of neurons located in close proximity with one another in a specific brain area, the motor cortex, the region of the cerebral cortex involved in the control and execution of voluntary movements. To illustrate the relevance of this approach we present a study aimed to estimate the neuronal cell complexity and rank the morphometric complexity motor cortical complexity across different mammalian species. Moreover, we compare the structural organization of the cerebral motor cortex across different mammalian species, of the horse with that of and selected primate species like chimpanzee and monkey. We highlight that assessment of neuronal cell complexity can be effectively done by using a suitable measure of statistical dispersion such as the mean absolute deviation – MAD.
In many different research fields, this concept of complexity has captured the interest of researchers and practitioners such as economists. Several scientific works have been dedicated to the study of economic complexity, both from the theoretical and the empirical point of view. Therefore today this issue is a real research area, rich of contributions and ideas. The importance of this topic is explained by the assumption that growth and development of a country mainly depend on the capabilities (human and physical capital, legal system, institutions, etc.) required to produce varied and sophisticated goods. Machinery and some types of chemicals are highly sophisticated goods; row materials and agricultural products are unsophisticated goods. In other words economic development depends on economic complexity
Quantitative determination of dietary lectin activities by enzyme-linked immunosorbent assay using specific glycoproteins immobilised on microtiter plates.
No full textAn immunoenzymatic method for the quantitative determination of dietary lectin activities employing immobilized glycoproteins was studied. Lectins from wheat germ (WGA), peanut (PNA), and jack bean (ConA) were added to microtiter plates coated with ovalbumin or asialofetuin and quantified by enzyme-linked immunosorbent assay (ELISA) with lectin-specific antibodies. ELISA responses for lectin activity were dose-dependent in the concentration range 30-1000 ng/mL for WGA and 80-1000 ng/mL for both PNA and ConA. Inhibition assays carried out with different saccharides confirmed that the binding of lectins to immobilized glycoproteins was specific. The proposed method is specific and sensitive, allowing the quantitative determination of lectin activities on raw samples by simple dilution of the extracts. Examples of application to wheat germ and roasted peanut extracts are reported
