Get PDFThis chapter gives an overview of currently used methods and techniques in enterprise architecture. Naturally, this description is a snapshot, and we cannot claim to be exhaustive, since the field of enterprise architecture is evolving rapidly. However, it provides this broad overview of current methods and techniques to give the reader an impression of the advances in this fiel
Case Studies
Get PDFTo obtain input from practice and to validate the concepts and techniques explained in the previous chapters, several partner-specific case studies have been executed. These have also served as an important means for knowledge transfer from research to practice. This chapter will elaborate on three of these case studies
Architecture Analysis
Get PDFThis chapter also explains what the added value of enterprise architecture analysis techniques is in addition to existing, more detailed, and domain-specific ones for business processes or software, for example. Analogous to the idea of using the ArchiMate enterprise modelling language to integrate detailed design models, the chapter demonstrates that analysis, when considered at a global architectural level, can play a role in the integration of existing detailed techniques or of their results
Service modelling
No full textThe development of enterprise services involves making design decisions at different levels, ranging from strategic to infrastructural choices, and concerning many different aspects, ranging from customer interaction to information registration concerns. In order to support an agile development process with short iterations through each of these levels and aspect, we need to manage the inherent complexity and support rapid feedback on the impact of design decisions across the various aspects of service development. The use of models can help to manage the coherence among the different aspects in service design and in facilitating and accelerating changes. Therefore, we propose a comprehensive framework and method for service modelling and model integration as an important ingredient of an agile service development methodology. This method is aimed at providing a shorter path between requirements and execution through the use of models to feed run-time execution engines, fast validation at the model level, support for communication with stakeholders, integration of different aspects, domains and fields of expertise, and consistency across the enterprise
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
Patterns for Agility
No full textThe use of patterns is an important practice in the agile software development community. There are many sources for patterns. In this chapter, we will examine several pattern collections and explore their potential contribution to system agility. We illustrate our pattern approach by a detailed examination of our collection of architecture patterns for multichannel management. The chapter is organized as follows: after a first part in which we define design patterns and discuss their most important characteristics, we describe our classification of several collections of patterns with respect to their contribution to agility. We conclude this chapter with an example of pattern usage in practice
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
