Designing Open Innovation Ecosystems for Small and Medium Enterprises
Full text linkEurope's transition to a circular economy is as much an environmental, economic and social necessity as it is an opportunity for European companies and citizens. Despite encouraging promises, many barriers hinder the circular transition of European companies, especially SMEs, which represent the bulk of Europe's industrial fabric. The presentation shows the case study of the 'DigiCirc' project (call H2020-INNOSUP) that creates and coordinates innovation ecosystems involving a broad range of stakeholders to foster connections and collaborations, supported by digital tools. The role of Systemic Designers in the project mainly focused on stakeholder selection and engagement, and on the training of participants on circular economy knowledge and systemic approach methods. The authors offer some reflections starting from the project's experience to understand how Design, in particular Systemic Design, can contribute to the creation of digital innovation ecosystems and how it can help enterprises overcome the barriers identified in the literature and past experiences. The aim is to open the debate on sustainability transitions and practical co-design experiences with stakeholders to foster those transitions. Authors are addressing design scholars and practitioners dealing with innovation and transition of socio-technical systems within industrial and cross- disciplinary environments
Systemic design for sustainable territorial development: ecosystem definition to support autopoietic local economies
Full text linkTo meet the current challenges to fight global and interconnected problems as waste production, systemic thinking is needed to provide a new cultural paradigm to create Sustainable, Circular and Blue Economies. One action can be done spotlighting the local territory in which we are living every day enhancing cultural and natural resources, indeed of considering it as a place where the products are manufactured, travel everywhere and leave only waste. Systemic Design can
provide an answer creating eco-innovation and environmental, social and economic sustainability, especially at the local level. A multiple case-study analysis on previous projects on Systemic Design has conducted to understand the principal barriers in their implementation and their outcomes to reach sustainable territorial development. After the identification of the new opportunities created at the entrepreneurial level, finally, it is designing the entrepreneurial ecosystem of innovation to foster Systemic sustainable projects framed in a specific context of referenc
Design of an ecosystem to foster systemic eco-innovation. Systemic design for autopoietic local economies
Full text linkThe current global environmental situation, with its interconnected problems, requires holistic approaches to provide a cultural paradigm shift and a different economy to overcome the linear one. Systemic Design (SD) can represent a solution creating opportunities for eco- and system innovation, especially in the manufacturing sector, which will soon face a revolution in the production model. Thus, SD can help achieve environmental and economic sustainability at the local level. A multiple case study analysis on SD projects was developed to understand the significant eco-entrepreneurial opportunities that have emerged and the barriers for their
implementation. Finally, an ecosystem is designed to foster systemic innovation based on helix innovation models and identify the facilitator for its creation, namely, the ‘local systemic network booster’
Bisanzio fino alla quarta crociata
No full textIl saggio traccia una sintesi della civiltà bizantina, dalla fondazione di Costantinopoli alla Quarta Crociata. A tutti gli effetti continuazione dell'impero romano, Bisanzio riuscì ad assimilare positivamente le Völkerwanderungen che determinano il crollo della prima Roma, facendo della multietnicità e del dinamismo verticale delle élites un punto di forza e una costante. Se nell'effimero progetto giustinianeo di riunificazione dell'impero universale prevalevano ancora una gravitazione occidentale e un’ottica vetero-romana, il superamento, a partire da Eraclio, della prospettiva italocentrica segnò il vero inizio dell'età bizantina. A Eraclio vanno ascritti due traguardi fondamentali: la creazione del sistema dei temi e il definitivo soggiogamento dell’impero persiano, nella gran parte dei cui ex-territori subentrerà ben presto, tuttavia, il nuovo interlocutore arabo. Tra il VII e l’VIII secolo, con l'accentuazione dei tratti aneuropei in campo economico, sociale, artistico, culturale, si assiste alla vera e propria nascita della concezione bizantina del potere. L’età dell'iconomachia, a lungo giudicata “buia”, coincide in realtà con una fase di prosperità economica: il compiersi del processo di deurbanizzazione e la trasformazione territoriale favoriscono l’accentuarsi della vocazione statalista e predispongono il grande “risorgimento culturale” del IX-X secolo. La sconfitta dell'iconoclasmo vede anche la sconfitta del platonismo e l'affermarsi dell'aristotelismo come filosofia ufficiale del cristianesimo medievale. Il regno di Basilio I e della dinastia macedone segna la cosiddetta "età d'oro" dell'impero bizantino. Il X e XI secolo conoscono più tormentati rapporti tra stato e chiesa, che culminano nello scisma del 1054 tra chiesa d’oriente e chiesa d’occidente (in definitiva sfida del patriarca Cerulario al basileus) e un incremento politico ed economico della nobiltà militare provinciale, che si affermerà definitivamente con la dinastia dei Comneni. Proprio con il regno comneno, in particolare con la concessione dei privilegi commerciali a Venezia da parte di Alessio I, deve farsi coincidere l’inizio della fase calante dell'economia bizantina, ininterrotta fino al XV secolo, simmetrica e inversa all'ascesa del protocapitalismo occidentale dei traffici, cui l’antica egemonia di Bisanzio sarà progressivamente sottomessa e la sopravvivenza stessa della basileia infine sacrificata. Al riaccendersi della prospettiva di restaurazione dell'impero universale corrisponderà – nelle forme del ripiegamento sociale e dell'indebolimento statale – maggiore vulnerabilità nella politica pratica. Con queste premesse Bisanzio subirà, nel 1204, la forza distruttiva della “deviazione” della Quarta Crociata: una catastrofe inaspettata e forse per questo ancora più traumatica della definitiva caduta del 1453 sotto i turchi osmani.
This essay outlines the history of Byzantine civilisation from the founding of Constantinople to the Fourth Crusade. In every way a continuation of the Roman empire, Byzantium succeeded in assimilating to positive effect the Völkerwanderungen that determined the fall of the first Rome, creating a point of strength and allegiance out of the multi-ethnic, ascendant vertical dynamism of the élites. If gravitation toward the West and an antiquated Roman perspective still prevailed in Justinian’s ephemeral project to reunify the universal empire, the shift beyond the Italo-centric perspective from Heraclius on marked the true beginning of the Byzantine era. Two fundamental achievements are ascribed to Heraclius: the creation of the system of themes and the definitive subjugation of the Persian empire, to whose ex-territories, however, the new Arab interlocutor would soon succeed. Between the 7th and 8th centuries, with the accentuation of non-European traits in economic, social, artistic, and cultural fields, we begin to see the emergence of the authentic Byzantine concept of power. Long considered “dark,” the age of iconomachy coincided, in reality, with a phase of economic prosperity. The culmination of the process of de-urbanisation and transformation of the territory favoured the accentuation of a state-centred vocation and set the stage for the great “cultural revival” of the 9th and 10th centuries. The defeat of iconoclasm also saw the defeat of Platonism and the affirmation of Aristotelianism as the official philosophy of Medieval Christianity. The reign of Basil I and the Macedonian dynasty marked the so-called “golden age” of the Byzantine empire. The 10th and 11th centuries saw more tormented relations between church and state, culminating in the Schism of 1054 between the Eastern and Western churches (ultimately the patriarch Cerularius’ challenge to the basileus) and a political and economic increase in the provincial military nobility that would assert itself definitively with the Comnenian dynasty. The beginning of the decline of the Byzantine economy - uninterrupted until the 15th century, symmetrical in nature and the inverse of the ascent of Western trade proto-capitalism to which the ancient hegemony of Byzantium would be gradually subjugated and the very survival of the basileia ultimately sacrificed - began precisely with the Comnenian dynasty, in particular, with the concession of commercial privileges to Venice by Alexius I. To the reawakening of the prospect of a restoration of the universal empire would correspond – in the form of social withdrawal and weakening of the state – greater vulnerability in political practice. Under these conditions Byzantium would, in 1204, be subjected to the destructive force of the “detour” of the Fourth Crusade: an unforeseen catastrophe and perhaps for this reason even more traumatic than the definitive fall in 1453 at the hands of the Osmanli Turks
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Some notes on the algebraic structure of linear recurrent sequences
Full text linkSeveral operations can be defined on the set of all linear recurrent sequences, such as the binomial convolution (Hurwitz product) or the multinomial convolution (Newton product). Using elementary techniques, we prove that this set equipped with the termwise sum and the aforementioned products is an R-algebra, given any commutative ring R with identity. Moreover, we provide explicitly a characteristic polynomial of the Hurwitz product and Newton product of any two linear recurrent sequences. Finally, we also investigate whether these R-algebras are isomorphic, considering also the R-algebras obtained using the Hadamard product and the convolution product
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 linkWe 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
