Singular PDE's geometry and boundary value problems
Local and global existence theorems for boundary value problems in singular PDE's are considered. In particular, surgery techniques and integral bordism groups are utilized, following previous works by A.Pr'astaro on PDE's, in order to build global solutions crossing also singular points and to study their stability properties.

Geometry of PDE's. III(II): Webs on PDE's and integral bordism groups. Applications to Riemannian geometry PDE's
By using previous results by A.Pr\'astaro on integral bordism groups of PDE's, and some issues of
the companion paper, we characterize in a
geometric way local and global solutions of (generalized) Yamabe
equations and Ricci-flow equations. We prove that such results help to find natural linear and parallel webs on a large category of
PDE's, that are important in order to find regular and singular
solutions on such PDE's. In particular, by applying algebraic
topologic methods on the Ricci-flow equation we definitively prove
that the Poincar\'e conjecture on the -dimensional manifolds is
true
The Routledge Companion to Global Value Chains: Reinterpreting and reimagining mega trends in the world economy
The Routledge Companion to Global Value Chains: Reinterpreting and reimagining mega trends in the world economy, to be published by Routledge in 2021.
Megatrends are deep-set trajectories of change that will reshape the landscape over the next few decades. Megatrends herald both challenges and opportunities. With the ever growing interest among business leaders and academics into global value chains or GVCs, this reference work fills in the gap in existing literature by portraying the current state of play of GVCs and offering an analysis of the megatrends in 3-D printing, smart specialisation, emerging technology enabled services, data analytics targeted at micro multinationals, start-up entrepreneurs, public sector and middle markets.
The first sections are essentially intradisciplinary in character, seeking to explore historical aspects of GVCs. The sections cover the discipline of operations and supply chain management, the history of emerging supply chain technologies, impact of interfirm collaboration and theory and practice across sectors, technologies and economies. The final section assumes a more interdisciplinary approach and examines various topics by industry sector where operations and supply chain interfaces with the economy, society, culture, and politics.
This comprehensive handbook provides a timely analysis of leading edge global practices in one volum
Dynamic Capabilities for Service Innovation in Service Systems
One of the principal drivers of productivity growth is innovation, which includes not only technological but nontechnological innovations. A key element of nontechnological innovation is skills which drives a large part of productivity improvement at the organizational level. Scholars have enunciated that innovation in services is brought to market through collaboration, asset orchestration, technological adoption, and knowledge-based competencies. To this effect, the role of human capital in promoting service innovation is identified in the innovation literature. Further, service innovation in a service ecosystem is centered on the resource-based definition, where services are treated as an application of competencies, making use of knowledge, skills and experience of all stakeholders. In addition, the process-based definition of service highlights the important role customers play in the service production process, where the customer themselves are an input to the service delivery process. Amidst resource limitations and acute competition, service firms need to therefore not only upskill the human talent of their employees and customers, but also reconfigure, renew, and redeploy resources and capabilities on an ongoing basis. This indeed highlights the importance of capabilities required to facilitate the creation of sustainable competitive advantage, which are not ubiquitously available in large proportion amongst service organizations. It is in this context that we identify and explore in this chapter the role played by service firms’ learning capacity to deploy operational and dynamic capabilities across service systems. This chapter highlights an entire suite of dynamic capabilities which are made up of higher order competencies, such as relationship capital, organizational learning, collaborative agility, entrepreneurial alertness, innovative capacity, and customer engagement, which are instrumental to service firms for innovation
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
Variations on the Author
“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
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
