Experimental investigations into gender, group dynamics and emotions
No full textThis thesis consisting of three chapters, uses laboratory and online experiments to investigate the interplay of gender, group dynamics and emotions. Chapter 1 employs a laboratory experiment to investigate how the gender of a group leader
affects the willingness of a group member to contribute. The results of Chapter 1 reveal that when paired with a leader of a different gender, group members display a greater inclination to contribute, which potentially improves group performance. Emotions have received little attention in studying deviations from Bayes’ rule. Therefore, I conduct an online experiment to uncover the role of induced emotions in belief updating in Chapter 2. I find the existence of symmetric belief updating: Participants statistically weigh good news and bad news similarly in all treatment groups. Besides, participants neglect prior beliefs. With respect to gender differences
in belief updating, I find that men significantly weigh less on good news when they are induced with fear compared to the other two treatment groups. The findings of Chapter 2 help to explain anomalies in marketplaces and gender differences in self-confidence. In Chapter 3, I use a laboratory experiment to study the impact of induced emotions on the group member’s willingness to answer for the group. Individual performance is not affected by treatments. With induced pleasure, high-performing
women exhibit a greater willingness to answer for their group. Results of Chapter 3 suggest that workplaces with positive emotions have the potential to reduce gender gaps in leadership and contribution, thus increasing engagement and
productivity
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

Event-triggered control and filtering for networked systems based on network dynamics
No full textWith the development of computing and communication technology, networked systems
in which information is exchanged through communication networks have become
prevalent in a variety of practical applications. A considerable number of these
systems have scarcely adequate computation and communication network resources.
Notice that, network dynamics usually affect the quality of the performance of networked
systems; network-based control or filtering design generally interferes with
the quality of service of communication networks. Therefore, successful implementation
of networked systems over communication networks requires the adequate
integration of control or filtering with intelligent computation and communication
networks. This research establishes an information scheduling middleware to effi-
ciently utilise the limited communication resources and the computation capacity
while preserving the desired performance of networked systems. In this proposed
middleware, an event-triggered scheme is given to provide a tradeoff between the
performance of networked systems and the utilisation of communication network
resources. A scheduling mechanism is derived to avoid traffic congestion in the
communication network by introducing a fluid-flow model. By using this information
scheduling middleware, the issues of network-based control and filtering are
investigated. First, a fluid-flow model of the communication network and an eventtriggered
scheme are integrated to develop a new framework, in which the criteria
of stability and stabilisation are derived for networked systems under simultaneous
consideration of control system performance and network dynamics. Second, based
on network dynamics, an online scheduling strategy is proposed to design the H∞
filter for networked systems in the framework with the information scheduling middleware,
the Information Dispatching Middleware (IDM). Third, the IDM is applied
to distributed control for large-scale networked systems and a codesign method is
obtained to determine the parameters of the IDM. Fourth, the mechanism of the
IDM is analysed to investigate the cooperation between the Information Selection
Module and the Congestion Avoidance Module in the IDM. Based on the IDM, distributed
filters are designed considering the dynamics of communication networks.
Finally, numerical and practical examples are given to demonstrate the effectiveness
and advantages of the proposed information scheduling middleware
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
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
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
