Business Model in Air Transport: Evolution of Innovation Concept
Full text linkWith the advent of the knowledge society, new opportunities,
business models and concepts have emerged in most industrial sectors and in
particular in the transport sector. The European air travel market, dominated
by airlines, influenced to varying degrees from their countries of origin, has
been, since the early nineties, completely revolutionized by the entrance in
the competitive arena of several small companies, which, in accordance with
the principles of „disruptive innovation‟, have completely changed the field
of passenger transport. To understand how this was possible, it is necessary
to investigate, just with the help of these new tools of Strategic Management
as the business models, about the way in which these airlines are able to
generate their business and create value.
This work aims to analyse the close relationship between innovation of
product / service and corporate business model in order to understand the
dynamics of the relationship. Various contributions from literature showed
how the concept of innovation within the company has evolved over the
years and what were the approaches used to study it. This analysis begins
with the study of the contributions of Schumpeter, the first economist to
write about innovation and author of the dynamic development model and
creator of the first distinction between innovation and invention. His theories
have made a major contribution in this area, but none the less were also
constructively criticized by other economists such as Freeman, who
introduced the concept of incremental innovation and analysed the factors
triggering innovation. Albernathy and Clark then added another fundamental
element of analysis: the competitive environment. They studied the influence
of innovation on those factors that are considered essential to achieve a
competitive advantage. The same Albernathy, with Utterback, then studied
the dynamics of innovations over time. Each of the cited authors analysed
the phenomenon of innovation in a different light and all of their
contributions allows for a broad and comprehensive concept. The picture is completed by adding the recent contributions of Christensen, who has taken
up and deepened the concepts of "sustaining innovation" and " disruptive
innovation" and, especially, began to highlight how essential it is that
innovation is supported by a suitable business model. In this regard, he has
shown that even the same business model can be object of innovation and
that this type of innovation is one of the main drivers of the creation of
competitive advantage
Statistical analysis of the circular economy for the intervention policies of the NRRP
No full textPurposeThis paper deals with analyzing the relationships between the domains of the Sustainable Development Goals (SDGs) and the Missions envisaged by the National Recovery and Resilience Plan (NRRP). Specifically, the authors refer to Mission 2 (Green revolution and ecological transition) and to the statistical indicators related to the M2C1 component (Circular economy and sustainable agriculture).Design/methodology/approachThe numerous data available were analyzed at a regional level using multivariate statistical methodologies (Totally Fuzzy and Relative method) capable of summarizing the various information to evaluate the current situation relating to the "circular economy and sustainable agriculture" component. The presence of multiple updated data allows for the development of a holistic approach to the evaluation of the local government policies in place and to be able to monitor the progress of the subsequent intervention policies of the Italian government.FindingsNo Findings.Originality/value NRRP represents an opportunity for development for the area, providing for reforms and substantial investments for the promotion of circular economy solutions, the improvement of the capacity for efficient and sustainable waste management, the strengthening of the infrastructures for treatment of waste and separate collection, the reduction of the North/South gap
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
