    Design for Territorial Ecology and a New Relationship between City and Countryside: The Experience of the Feeding Milano Project’

    No full text
    A smooth transition towards sustainability calls for a profound change in agriculture and its relationships with cities: there will be no sustainable agriculture and no sustainable cities without a redefinition of their mutual interactions; that is, without a new ecology of communities and places. This new territorial ecology is already appearing at the interfaces between cities and countryside, driven by a wave of social innovation. This is generating unprecedented food communities – producers and consumers defined by a place of origin and reflecting a new idea of ‘local economy’ based on food, agriculture, tradition and culture – where multifunctional farming, de-mediated food chains and urban activism merge. A project about Milano, the Feeding Milano Project is a good example of this emerging trend. It shows what a mix of bottom-up initiatives as well as design-led initiatives can do. This example, with other similar ones around the world, represents an innovative design process (planning by projects or also ‘acupuncture’ planning) capable of promoting and sustaining a new territorial ecology

    BIOHYDROGEN PRODUCTION BY DARK FERMENTATION: FROM LABORATORY TO FULL SCALE.

    Hydrogen is a promising, eco-friendly fuel for the future, especially when obtained from renewable sources such as anaerobic digestion (AD). After proving that biomass'composition is involved in the production of hydrogen, a comparison between single- and two-stage AD showed that the latter is not less convenient than the classical, single stage process. The addition of a further stage (microbial fuel cells) to AD reactors showed an interesting perspective for two-stage AD, which resulted in better total energy yields when compared to single-stage process. The process is feisable on full scale, but technical issues are to be solved in order to obtain better performances

    Ricerca, disegno industriale e innovazione: note a margine di un programma di dottorato

    No full text
    Dal 1990, quando ha avuto inizio, l'attività del dottorato di ricerca in disegno industriale presso il Politecnico di Milano è andata progressivamente strutturandosi intorno alle tematiche dell'innovazione, pur articolandosi in temi di ricerca molto eterogenei. Le ragioni di questo orientamento sono state determinate da fattori diversi, in parte interni alle dinamiche stesse della disciplina del disegno industriale, in parte derivati dalla percezione che proprio la crescente complessità del processo innovativo legittima e rende necessari approcci e forme di analisi che possono essere sviluppati adeguatamente all'interno di un programma di dottorato. Un numero significativo di ricerche - e le dissertazioni che ne sono derivate - ha così enfatizzato la rilevanza del cambiamento tecnologico, proponendo studi di impianto teorico orientati all'elaborazione di approcci sistemici, evolutivi, complessi. Indipendentemente dalle motivazioni che hanno condotto a privilegiare l'analisi del cambiamento tecnologico e dell'innovazione, gli sviluppi che ne sono derivati hanno contribuito in modo significativo a mettere adeguatamente in luce i fattori e gli elementi che stanno alla base dei processi di trasformazione dei prodotti, dei servizi, dei sistemi industriali. Infatti, quale assunto di base, è stata accolta un'accezione estesa di innovazione, considerata come un processo dinamico orientato al raggiungimento di vantaggi competitivi che coinvolgono lo sviluppo o il miglioramento sia di nuovi prodotti che di nuovi servizi, tecnologie, istituzioni, sistemi, soluzioni. Questo approccio esteso ha consentito di andare oltre gli ambiti convenzionali della scienza e della tecnologia, e di aprirsi all'orizzonte di quelle entità e attività sociali (come la comunicazione, l'organizzazione aziendale, l'istruzione, le istituzioni) che competono sul mercato e che rientrano nell'area di azione del disegno industriale. Tuttavia, le pagine che seguono non sono intese a indagare la natura dell'innovazione come materia di studio di un programma di dottorato. Piuttosto, si cerca di mettere a fuoco alcuni degli assunti che hanno costituito una sorta di traiettoria teorica che ha attraversato i programmi dell'attività di dottorato. Allo stesso tempo si propone un primo nucleo di risposte alla domanda: qual è l'obiettivo della ricerca di design? ( E, inoltre, qual è il ruolo di un dottorato di ricerca in disegno industriale?) Le riflessioni oggetto di questo saggio cercano da un lato di rendere il contesto teorico più ampio nel quale si è mossa l'attività di ricerca e dall'altro di sottolineare la rilevanza strategica che la ricerca di design può assumere

    Chlamydia-induced arthritis. Immunofluorescent antibody studies of the synovial fluid from 4 patients Clin Exp Rheumatol. 1992 Jul-Aug;10(4):

    Using two monoclonal antibodies in direct immunofluorescence we found material which could be identified as elementary bodies and cytoplasmic inclusions of Chlamydia trachomatis (Ct) in the synovial fluid of 4 patients affected by acute seronegative oligoarthritis. The finding of Ct in synovial fluids is a well known occurrence and has been demonstrated during the last few years in patients affected by seronegative oligoarthritis. However the fact was impossible to culture viable Ct from synovial fluid led researchers to believe that the local immune responses might be triggered by bacterial antigens in the non viable form.The findings described in this work suggest that in our cases the bacteria was present in metabolically active vegetative form

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Research, Industrial Design and Innovation: Reflection around a Doctoral Programme

    No full text
    Since 1990, when it first started, the domains of research investigated by the doctoral activity in industrial design held within the Politecnico of Milano were mainly centred on innovation-related phenomena and theory. Such attention was due to various factors, partly internal to the dynamics of the discipline of industrial design, partly related to the perception of the growing complexity of the innovative process, thus motivating in-depth analysis and new approaches to emerging domains. A relevant number of investigations emphasized the importance of technological change, orienting the direction of conceptual analysis towards systemic, evolutionary, complex approaches. Whatever the motivations for the analysis of technological change and innovation, this field of enquiry highlighted the factors and fundamental ingredients of the process of development and transformation of industrial products, services and systems. Moreover, as a starting point a broad view of innovation was assumed, being a dynamic process related to achieving competitive advantages involving the development or improving of new products, services, technology, processes, institutions, systems, solutions. This view of innovation encompasses not only science and technology, but the range of economic and social activities competing in the marketplace and relevant to design in areas such as communications, corporate organizations, education, institutions. However, this contribute is not intended to explore the nature of innovation as a subject of study of a doctoral programme. Rather, it stylizes some recent theoretical assumptions as a trajectory of ideas which permeates the doctoral programme activity. At the same time it proposes an answer to the very basic question: what is the purpose of design research? (And consequently, what is the role of a Ph.D. in industrial design? The following reflections, simply divided into two sections, try to render the context which oriented research activity and the strategical relevance design research can achieve. Ed. V. Margolin, R.

    Variations on the Author

    Full text link
    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
