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
Exploring the Origins of New Transaction Costs in Connected Societies
No full textThere is a considerable amount of literature in management science, which claims that the digital economy is a frictionless economy, where hierarchies and institutions disappear replaced by dynamic and self-organized webs of companies and consumers. This vision may influence the way managers build market strategies and manage organizations, but also the way policy-makers address relevant issues concerned with the so-called digital divide in the knowledge society. In this chapter we have addressed the frictionless vision, challenging the communication symmetry fallacy, on which is based the idea that the network economy is automatically eliminating the information and institutional hierarchies (even though we still believe that the Internet introduces radical changes in the way economic institutions are built and the way businesses are conducted). We provide primary and secondary empirical evidence that does not support the frictionless hypothesis. The complexity of our interconnected world, the evolutionary nature of trust and learning dynamics, and the economics of mediation (the economics of relationships plus the economics of information infrastructure), play a major role in both the creation and reduction of these new hierarchies and transaction costs in digital society. The result is complex and not deterministically driven by network technology.</jats:p
Self-Organization and New Hierarchies in Complex Evolutionary Value Networks
No full textThis chapter, with a broad theory building goal, addresses these two questions: “how the new network-based forms of coordination emerge, and how can they change the management of value exchange dynamics on complex cognitive networks?” We can find a useful answer by using an interdisciplinary approach. New institutions do not form through costless trust and order-for-free self-organization (the invisible hand of the market), but are managed as complex evolutionary value networks. This conceptual framework can help managers to design more cooperative structures and nodes to negotiate network structure and power. The design of the network matters. The network is the locus of learning but also the locus of social negotiation. The new institutions can be designed, even if this design looks more like a monitorial learning process and a design of the infomediation infrastructure than the well structured plans of old-fashioned management. The new network governance forms, and the logics that wants to build organizations as flexible and loosely-coupled systems of self-organized peripheries, also require that we build a new “ethics of network management” agenda.</jats:p
Service industrialisation and beyond: findings from a service networks project
No full textThis paper illustrates the findings of a project about the impact of digital technology on services. In this paper, we discuss the relevant literature in the service management and business networking fields, and our research findings from: 1) a multi-industry study for a government agency regarding changes in services observed through a 2003 to 2010 research; 2) a multi-case study of business networking in heritage tourism; 3) a case study of business networking in the advertising sector. The findings partially support, in our micro-level research, the service-industrialisation hypothesis developed at the macro (national economy) level, but also highlight important variance within sectors, best explained by a relationship-based approach to service management. Implications for business management and academic research will be discussed.services, service industrialisation, business networks, service networks, network marketing, relationship marketing, ICT, heritage tourism, advertising, fitness centres, market research, service management,
