Gli ecosistemi delle piattaforme digitali: stato dell’arte, strategie di envelopment olografiche, casi di studio
Full text linkLe piattaforme digitali stanno penetrando sempre più nel cuore della società, rimodellando le organizzazioni, le istituzioni, le transazioni economiche e le pratiche socioculturali e costringendo i Paesi ad adattare le proprie strutture politiche, istituzionali e legali. Se da un lato le piattaforme digitali riflettono la digitalizzazione del mondo, dall'altro lato, sono diventate sempre più centrali nella costruzione di culture, società ed economie moderne. La piattaformizzazione sembra essere una forza demiurgica, che sta sempre
più (ri)plasmando questo millennio e le sue strutture socioeconomiche, tecnologiche e fisiche, le istituzioni e le vite umane. Nonostante il fenomeno della piattaformizzazione e le piattaforme digitali siano sempre più sotto i riflettori della ricerca economico manageriale, in letteratura manca ancora un quadro teorico e strategico che spieghi come emerge un ecosistema della piattaforma digitale e come esso sia in grado di replicarsi da un mercato all’altro. Inoltre, anche se molti studi abbiano sottolineato che le città
rappresentano il cuore della società e, dunque, uno dei principali ecosistemi ad essersi piattaformizzato, non è ancora chiaro come gli ecosistemi delle piattaforme digitali siano riusciti a piattaformizzare gli ecosistemi urbani. Questo lavoro consiste in una ricerca qualitativa che prova a colmare le suddette lacune, integrando la letteratura sugli ecosistemi delle piattaforme digitali e sulle città piattaforma in tre modi. In primo luogo, partendo dalla letteratura sugli ecosistemi delle piattaforme digitali e adottando il pensiero sistemico, il capitolo 1 analizza l’ecosistema della piattaforma digitale attraverso la duplice lente struttura-sistema. Il pensiero sistemico viene utilizzato per esporre in maniera originale il quadro teorico esistente. Ciò non solo consente di mettere in luce come emerge un ecosistema della piattaforma digitale ma permette di distinguere la dimensione strutturale (ossia la piattaforma digitale) dalla dimensione sistemica che caratterizza l'ecosistema emergente (non lineare e talvolta imprevedibile). In secondo luogo, il capitolo 2 fornisce un avanzamento concettuale inerente alle strategie di envelopment attraverso le quali da un ecosistema della piattaforma digitale ne fioriscono degli altri. È stata identificata e analizzata la strategia olografica di envelopment come un’ulteriore tipologia di envelopment che consente agli ecosistemi delle piattaforme digitali di riprodursi oltre i confini del proprio mercato originario, riuscendo ad entrare e/o creare diversi mercati e settori industriali anche lontani dal proprio. Infine, il capitolo 3 fa luce sulle modalità attraverso le quali gli ecosistemi delle piattaforme digitali sono riusciti a diventare degli snodi cruciali attorno ai quali si articola, emerge e si sviluppa l’ecosistema urbano. In particolare, attraverso l’analisi e la comparazione di due casi di studio (l’ecosistema dell’iPhone e l’ecosistema Android di Google) viene sviluppato un quadro teorico che spiega come l’ecosistema dello smartphone è riuscito a piattaformizzare gli ecosistemi urbani. Le suddette concettualizzazioni hanno importanti implicazioni
teoriche, manageriali e politiche. Dal punto di vista teorico, il lavoro discute la necessità di adottare l’ecosistema come la principale unità di analisi utile per comprendere un paesaggio socioeconomico dai confini sempre più sfumati. La ricerca lega anche le strategie di espansione degli ecosistemi delle piattaforme digitali al megatrend della piattaformizzazione della società. Dal punto di vista manageriale, lo studio individua la strategia olografica di envelopment come una strategia di espansione che supporta il
platform sponsor nelle dinamiche della multipoint competition. Inoltre, l’analisi delle modalità attraverso cui gli ecosistemi delle piattaforme digitali stanno piattaformizzando le città rappresenta un valido supporto per le amministrazioni pubbliche intenzionate ad aderire attivamente agli ecosistemi delle piattaforme digitali al fine di efficientare i servizi delle proprie città. Infine, dal punto di vista delle politiche, lo studio individua le questioni cruciali per i responsabili politici nella regolamentazione dell'impatto che gli
ecosistemi delle piattaforme digitali stanno avendo sulla società
Platform-based innovation ecosystems. Entering new markets through holographic strategies
No full textThe platformization seems to be a demiurgic force, increasingly (re)shaping this millennium and its socio-economic, technological and physical structures, institutions, and human lives. Innovation ecosystems are experiencing this platformization, leading to the rise of platform-based innovation ecosystems. However, the industrial and managerial literature still lacks a shared definition, a consistent theoretical and strategic framework to explain how platform-based innovation ecosystems emerge and replicate from market to market. This conceptual work attempts to fill those gaps by integrating the extant literature on innovation ecosystems in two ways. First, moving from the literature on innovation ecosystems and industry platforms, using systems thinking framing, it explains the platformization of innovation ecosystems through the double lens structure-system. Second, it identifies the holographic strategy as one of the typical patterns featuring platform-based innovation ecosystem envelopment beyond extant market boundaries. These conceptualizations have insightful theoretical, managerial, and policy implications. In particular, the work discusses the ecosystem as a valid unit of analysis for understanding such an unprecedented shaped-by-platform landscape. Then, it describes the growth strategies of the platform-based innovation ecosystem supporting the platform sponsor in mastering multipoint competition. Eventually, the study pinpoints crucial issues for policymakers in regulating the impact that platformization is having on society
Digital Platform Ecosystems for Sustainable Innovation: Toward a New Meta-Organizational Model?
No full textThis work aims to develop a conceptual model to support countries, institutions, and firms toward the accomplishment of present Agenda 2030 sustainability goals. The last two decades have seen a growing interest in sustainability. Climate change, resource scarcity, multipolarity of interests, mistrust and delegitimization of institutions are just some of the critical issues that need to be addressed. There is broad consensus on the urgency of generating further social, environmental, and economic innovation to address these challenges, reshaping global markets, and offering new spaces of action to firms and institutions. Accordingly, there also is a wide search for new models of organizing firms. Digital platforms are among those. Moreover, since digital platforms require coordination among multiple actors and interests in order to succeed, they may also be conceptualized as meta-organizations, less hierarchical than firms yet more tightly coupled than markets. However, despite the wide literature on platforms, this organizational lens seems not to have been taken into the right consideration. This conceptual work aims to fill this gap, providing a framework that clarifies why and how a digital platform ecosystem could configure a sustainable meta-organizational model, and also providing the main steps to build it
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
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
