introduced for automatically generated PLC-Code on the working cell level. Thereafter, it would come with the explanation of interlock error checking and handling methods for both automatic and manual modes. The basic idea in this part is to compare the estimated operation time with the real one for each mutual zone, so as to detect the overtimes for calculating the global optimized operation
sequence. For verifying the proposed approach, the programs and the result of an experimental simulation were given at the end of the thesis. One thing to notice is that the estimated operation time for each mutual zone is the total time span for the zone being used, but does not include detailed time for single operations. However, each single operation time must be estimated correctly so that the zone’s total time span could be calculated correctly, reasonably and feasibly. Additionally, since the generation process in the thesis adopted the assembly technique [1], there are also possibilities for other sub-processes in the cell to reuse the existing information.Contents

Handling communication of a family business during a scandal : exploring emotional and rational apology strategies in family-owned hospitality firms
No full textThis thesis examines how family-owned hospitality businesses can shape public perception through targeted crisis communication during internal controversies. Drawing on several theories, such as Social Identity Theory and Socioemotional Wealth Theory, this thesis explores how emotional and rational apologies affect consumer perceptions of credibility, forgiveness, and reputation. Using a 2x2 experimental design, the survey manipulates the intensity of family branding and the type of apology presented in a crisis scenario. Results indicate that rational apologies are generally perceived as more credible and lead to higher forgiveness than emotional ones. Additionally, individuals who recognized a stronger family brand rated the company more favorably, regardless of the objective manipulation. However, the interaction effects between branding and apology strategy were not significant, but the findings underscore the importance of stakeholder perception in crisis communication. This quantitative study contributes to research on crisis response in family firms and offers theoretical implications for managing a family brand reputation under threat.Florian Luo Jia WuMasterarbeit Universität Innsbruck 202

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
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
