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
Experimenting with Meaning: Reallabor as a Travelling Concept in Germany’s Innovation Landscape
The concept of Reallabore (real-world laboratories) has undergone remarkable semantic evolution in Germany - rooted in the experimental turn in social sciences, shaped in sustainability research, and culminating in national innovation policy. This paper frames Reallabore as a travelling concept: a term that shifts in meaning as it moves across institutional, disciplinary, and political contexts. Drawing on perspectives from economic geography, it traces four distinct phases in the evolution of the term, highlighting the tensions and strategic translations that have shaped its development. Understanding such conceptual trajectories is key to interpreting the performative power of innovation discourse in regional policymaking
The agency and geography of socio-technical transitions: the case of urban transport innovations
The objective of this cumulative thesis is to gain deeper insights into the interplay of agency and structure through the empirical example of emerging technologies in the context of Industry 4.0. To achieve this goal, it enriches the theoretical background from evolutionary economic geography with insights from transition studies and management studies. Empirically, the analysis focuses on novelty creation toward intelligent transport systems in an urban environment. This encompasses software solutions such as big data platforms for traffic management, the Internet of Things to create a network of various objects and subjects within the city, or the development of autonomous vehicles. This thesis formulates four overarching research purposes: (1) comprehending socio-technical transitions during Industry 4.0 from an agency-based perspective; (2) understanding how agency facilitates or hinders innovation development; (3) identifying the impact of multi-scalar and cross-sectoral relations; and (4) integrating different theoretical approaches to gain a holistic understanding of the empirical domain. The thesis adopts a qualitative research design with a philosophical grounding in critical realism, drawing on semi-structured expert interviews, literature reviews, and document and network analysis. The main contribution of this thesis rests on four distinct research papers. A systematic literature review sets the conceptual basis for the analysis, identifying future research avenues based on the existing research body. The first case study analyzes the development of an app-based solution for managing urban logistics in Barcelona from a multi-level perspective. The other two case studies investigate the evolution of advanced air mobility in Germany and the city of Hamburg
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

Dispelling the Myths Behind First-author Citation Counts
We 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
