Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Identification of Influentials in virtual social network: an agent-based simulation model of social influence processes
No full textDie zunehmende Virtualisierung von gesellschaftlichen Sozialstrukturen durch den Social Media Bereich und insbesondere durch die virtuellen sozialen Netzwerke stellt die Marketingforschung vor neue Herausforderungen. Aufgrund der technologischen Entwicklung des Web 2.0 entstehen für Konsumenten schnelle und einfache Kommunikations- und Interaktionsmöglichkeiten zum Erfahrungsaustausch über die Produkte und Dienstleistungen eines Unternehmens. Innerhalb eines virtuellen sozialen Netzwerkes existieren Influentials, die aufgrund ihrer kommunikativen Verhaltensweisen und der netzwerkstrukturellen Einbettung eine einzigartige soziale Beeinflussungsfähigkeit aufweisen. Für das Marketing der Unternehmen stellen das Verständnis über die sozialen Beeinflussungsprozesse und die Identifikation der Influentials die zentralen Erfolgsfaktoren dar, um die Konsumenteninteraktion im Sinne der Unternehmenszielsetzung zu beeinflussen. Bisherige Analyse- bzw. Identifikationsmethoden für diese Influentials vernachlässigen jedoch die bedeutsame interpersonelle Perspektive. Die netzwerkstrukturelle Einbettung der Konsumenten bzw. Individuen sowie deren Kommunikations- und Interaktionsprozesse untereinander führen zu einem dynamischen, nichtlinearen und komplexen Sozialsystem. Bei der Untersuchung dieser Dynamiken stoßen traditionelle Analysemethoden der Marketingforschung an ihre Grenzen. Deshalb entwickelt der Verfasser ein agentenbasiertes Simulationsmodell, um das individuelle Konsumentenhalten als komplexes und dynamisches System abzubilden. Die Simulationsergebnisse deuten darauf hin, dass die Influentials weder über eine strukturell besonders bedeutsame Position innerhalb des Netzwerkes verfügen, noch eine erhöhte soziale Aktivität aufweisen. Die bisher verwendeten Verfahren der strukturellen sozialen Netzwerkanalyse und der sozialen Aktivitätsanalyse sind deshalb nur eingeschränkt zur Identifikation von Influentials geeignet. Aus einer interpersonellen Analyseperspektive zeigt sich, dass die Influentials eine besonders hohe wahrgenommene Glaubwürdigkeit aufweisen und das soziale Umfeld dieser Individuen durch eine hohe Empfänglichkeit für soziale Beeinflussungen gekennzeichnet ist. Die agentenbasierte Simulation erweitert somit das Verständnis über das sozial beeinflusste Konsumentenverhalten und liefert damit wertvolle Hinweise für die praxisnahe Identifikation von Influentials in einem virtuellen sozialen Netzwerk.Virtual social networking sites have become more and more popular over the last few years, attract millions of users worldwide and are growing exponentially. The increasing amount of virtually connected consumers leads to a social-driven information exchange about products, brands or services. Within virtual social networks, influentials can be considered as key users with high influence capabilities, unique communication patterns and important structural network positions. For marketers an understanding of social influence is key to benefit from consumer-to-consumer interaction and to address potential new customers by utilizing these influentials. So far, virtual social network analysis neglects interpersonal factors of influence as well as an individual consumer decision making perspective. The analysis of individual interaction and the lack of empirical data from virtual social networks require a research method, which models individual consumer behaviors as a complex and adaptive system. Therefore, the author develops an agent-based simulation model to explore and to investigate social influence processes by integrating perceived social activity, perceived structural positions and interpersonal relationship characteristics with an individual decision making perspective. Simulation results indicate that important members in virtual social networks are inadequately identified either through structural network or activity analysis respectively. Hence, these methods are less appropriate to identify influentials within a virtual social network. The interpersonal analysis of the social influence processes shows that influentials are characterized by a high perceived credibility. Moreover, the social contacts of the influentials are highly susceptible for social influences. The agent-based simulation model provides a deeper understanding of social influence processes in virtual social networks and serves marketers as a superior opportunity for identifying socially influential network members
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
Designing Cross-Company Business Intelligence Networks
No full textBusiness Intelligence (BI) ist der allgemein akzeptierte Begriff für Methoden, Konzepte und Werkzeuge zur Sammlung, Aufbereitung, Speicherung, Verteilung und Analyse von Daten für Management- und Geschäftsentscheidungen. Obwohl unternehmensübergreifende Kooperation in den vergangenen Jahrzehnten stets an Einfluss gewonnen hat, existieren nur wenige Forschungsergebnisse im Bereich unternehmensübergreifender BI. Die vorliegende Arbeit stellt eine Arbeitsdefinition des Begriffs Cross-Company BI (CCBI) vor und grenzt diesen von gemeinschaftlicher Entscheidungsfindung ab. Auf Basis eines Referenzmodells, das existierende Arbeiten und Ansätze verwandter Forschungsbereiche berücksichtigt, werden umfangreiche Simulationen und Parametertests unternehmensübergreifender BI-Netzwerke durchgeführt. Es wird gezeigt, dass eine Peer-To-Peer-basierte Gestaltung der Netzwerke leistungsfähig und kompetitiv zu existierenden zentral-fokussierten Ansätzen ist. Zur Quantifizierung der Beobachtungen werden Messgrößen geprüft, die sich aus existierenden Konzepten zur Schemaüberführung multidimensionaler Daten sowie Überlegungen zur Daten- und Informationsqualität ableiten oder entwickeln lassen.Business Intelligence (BI) is a well-established term for methods, concepts and tools to retrieve, store, deliver and analyze data for management and business purposes. Although collaboration across company borders has substantially increased over the past decades, little research has been conducted specifically on Cross-Company BI (CCBI). In this thesis, a working definition and distinction from general collaborative decision making is proposed. Based on a reference model that takes existing research and related approaches of adjacent fields into account a peer-to-peer network design is created. With an extensive simulation and parameter testing it is shown that the design proves valuable and competitive to centralized approaches and that obtaining a critical mass of participants leads to improved usefulness of the network. To quantify the observations, appropriate quality measures rigorously derived from respected concepts on data and information quality and multidimensional data models are introduced and validated

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
