Analysis of impaired in vitro immunoglobulin synthesis in rheumatoid arthritis.

1990

Decreased immunoglobulin production in pokeweed mitogen driven lymphocyte cultures has been reported in rheumatoid arthritis (RA). Here various activators and experimental designs have been used to determine the contribution of B cells, T cells, or monocytes to this low response. Sixty patients with RA and paired controls were studied at the onset of disease and again six months later. Concentrations of IgA, IgG, and IgM in cultures of RA peripheral blood mononuclear cells stimulated with thymus dependent activators were already decreased at the onset of the disease. Six months later RA mononuclear cells produced even lower concentrations of immunoglobulin. In contrast, stimulation with a T…

The impact of privatization approaches on the productivity growth of the water industry: A case study of Chile

2015

Abstract The water industry faces the challenge of implementing privatization reforms. This process mainly adopts the following two approaches: the privatization of public water and sewerage services (WSS) and the privatization of water companies’ ownership. This paper investigates the impact of both privatization approaches on changes in productivity in the water industry. In doing so, the Luenberger productivity indicator (LPI) was computed for a sample of Chilean water and sewerage companies (WaSCs) for the period 1997–2013. Unlike the most commonly applied index (Malmquist productivity index), the LPI simultaneously takes into account output expansion and input contraction. The results …

Assessment of the influence of counter ions on biosorption of copper cations in brewer's spent grain - Waste product generated during beer brewing pr…

2019

Abstract The influence that conditioning leached ground barley grain (known as “brewer's spent grain” (BSG)) has on the effectiveness of copper cation sorption was analysed. Saturation with counter ions of functional groups present on the grain surface was carried out in hydrochloric acid, sodium hydroxide, sodium and calcium chloride solutions. For comparison, BSG was also conditioned in demineralised water. Spent barley grain is a by-product of the brewing industry which can be used as a biosorbent in the removal of heavy metals from waste water. Emphasis is placed on the effect of competitive sorption of copper and hydrogen cations and the negative influence of a solution alkalinisation …

Algorithms for rational discrete least squares approximation

1975

In this paper an algorithm for the computation of a locally optimal polefree solution to the discrete rational least squares problem under a mild regularity condition is presented. It is based on an adaptation of projection methods [8], [12], [13], [14], [18], [19] to the modified Gaus-Newton method [4], [10]. A special device makes possible the direct handling of the infinitely many linear constraints present in this problem.

La scuola e la società in John Dewey ai tempi della pandemia da Covid-19

2022

La pedagogia di John Dewey può essere oggi intesa come una risorsa utile per fronteggiare il periodo complesso e drammatico caratterizzato dalla pandemia da Covid-19. È per questo motivo che il contributo, attraverso alcuni riferimenti alle opere più significative della prospettiva deweyana, intende riflettere sull’attualità del pensiero deweyano, facendo un esplicito riferimento alla sulla sua idea di democrazia come a way of life e ponendo in risalto in che modo le scuole possano contribuire a fronteggiare circostanze complesse come quelle attuali, progettando e realizzando dei processi educativi mirati alla trasmissione e alla sperimentazione dei principi democratici e alla formazione di…

La scuola al servizio della democrazia: i princìpi ispiratori di John Dewey per l’interpretazione di Lamberto Borghi

2021

John Dewey ha dedicato molta attenzione al rapporto scuola-società, affermando come il modo di insegnare e di educare potesse favorire la creazione di una democrazia intesa non come un mero sistema politico, bensì come un a way of life. In tal senso, il contributo cha lo scopo di evidenziare come l’idea di Dewey di una scuola a servizio della democrazia si sia diffusa anche in Italia grazie al contributo di Lamberto Borghi. Quest’ultimo, nell’immediato secondo dopoguerra e attraverso l'influenza del pensiero di John Dewey, teorizzò infatti un’educazione volta allo sviluppo di una personalità comunitaria in grado di vivere in un contesto democratico nel pieno rispetto di ogni forma di divers…

L'educazione intellettuale: il rapporto fra docenti e discenti nell'ottica di John Dewey

2019

Attraverso alcune letture di John Dewey, il presente articolo presenterà l’idea di una relazione educativa incentrata sull’equilibrio tra docente e alunno e su un processo educativo finalizzato alla crescita intellettuale e all’avvenimento personale Inoltre, si rifletterà sull’importanza di realizzare tutto questo nelle attuali società tardo-moderne, nelle quali imparare a pensare rappresenta un’emergenza educativa impossibile da trascurare. Through some readings by John Dewey, this article will present the idea of an educational relationship focused on the balance between teacher and student on an educational process aimed at intellectual growth and at personal event. In addition, it will …

Il valore educativo dell’esperienza in John Dewey

2020

Uno dei principi cardine del pensiero di John Dewey è sicuramente quello di esperienza reputata generatrice di crescita e di formazione per ciascun individuo. Pertanto, questo contributo si propone come scopo quello di illustrare dapprima alcune opere della giovinezza, nelle quali Dewey, con un riferimento chiaro ed evidente a Immanuel Kant, ha maturato l’idea di un’esperienza produttrice di conoscenza e di maturazione umana e sociale; in un secondo momento verranno illustrati alcuni scritti della maturità, dove è possibile rintracciare un’evoluzione del concetto di esperienza, alla quale Dewey ha attribuito un valore educativo che doveva essere incoraggiato nei contesti scolastici del suo …

I luoghi dove realizzare il “nuovo individualismo” di John Dewey: il ruolo del metodo scientifico e della pratica educativa del riconoscimento

2021

This contribution aims to reflect on the concept of individualism as presented by John Dewey who used this word to indicate the unique and unrepeatable part of man, differentiating the “old individualism” from the “new individualism”. Taking into consideration the Deweyan theories of the first half of the twentieth century, with particular reference to the 1930 writing The Individualism Old and New, it is noted that Dewey criticized the existence of an “old individualism” intended as an emblem of egocentrism and of asociality, the causes of which were traceable to the advent of industrialization, social stratification and capitalism. According to him, these were people without a solid ident…
