The Communication Strategies and Customer's Requirements Definition at the Early Design Stages: An Empirical Study on Italian Luxury Automotive Brands
No full textAbstractAt the early stages of the product development, it is important to set up customer's requirements and translate these into the technical specifications with the highest level of precision since the changes in the late design phases have extremely high cost. These requirements are directly dependent on the correct and complete definition of perceived quality attributes. Such attention to the details is vital for the luxury car manufacturers since they are seeking to fulfill customer requirements with the high level of personalization. This research based on the perceived quality framework and presents findings from the empirical study of leading Italian luxury vehicle manufacturers. This research contributes to the existing debate regarding the correct definition of the customer's requirements and communication strategies. Moreover, it highlights possible ways to reduce information asymmetry between car manufacturers and customers
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
Visualising the Effect of Geometrical Variation in Assembled Products. Predicting Visual Quality Appearance
No full textToday, when an industrial design concept is evaluated in an aesthetic manner, little or no consideration is given to geometrical variation, i.e. the concept is evaluated with nominal geometry. If geometrical variation were considered as early on as in the concept phase, when industrial design concepts are evaluated, the possibility of discovering aspects that can influence the visual quality appearance would be enhanced. By using non-nominal models during the design process, important geometric aspects can be stressed and the need for physical prototypes and test series can be reduced. In the automotive industry, the relationships between different visible parts of the interior and exterior are critical for the overall visual quality appearance of the product. These relations should have a tight and parallel appearance. This thesis presents methods and a tool for predicting how geometrical variation affects visual quality appearance. The adopted approach has been to combine computer-aided tolerance analysis with high qualitative computer graphics in order to visualise the effect of geometrical variation. The two main relations - gap and flush of a split line - are adjusted in accordance to calculated geometrical deviation. Furthermore, the ability to judge distance in virtual environments is also investigated. If virtual non-nominal models are to be used for evaluation of variation, it is essential to have knowledge about the difference between the estimated and real actual distances. Otherwise, decisions are made based on the wrong facts, and this contributes to increased uncertainly. An initial study showed that there is a significant difference in perception between physical and virtual representations. A second study investigated how ten different parameters influenced the ability to judge distance. Significant main effects and interactions were identified for the two relations, gap and flush. Finally, all methods and the tool have been implemented in industrial projects in order to evaluate whether developed methods and tools actually work as intended. Qualitative analysis of collected data showed that proposed methods and tools gained high acceptance from both industrial designers and engineering designers. Although many aspects still remain to be investigated further, the final conclusion for this project is that tremendous progress has been achieved towards the aim of predicting visual quality appearance in an accurate and reliable manner
