Satisfying user needs at the right time and in the right place: A research preview
No full text[Context and motivation] Most requirements engineering (RE) approaches involve analysts in gathering end-user needs. However, we promote the idea that future service-based applications should support end-users in expressing their needs themselves, while the system should be able to respond to these requests by combining existing services in a seamless way. [Question/problem] Research tackling this idea is limited. In this research preview paper we sketch a plan to investigate the following research questions: How can end-users be facilitated by a system to express new needs (e.g. goals, preferences)? How can the continuous analysis of end-user needs result in an appropriate solution? [Principal ideas/results] In our recent research, we have started to explore the idea of involving end-users in RE. Furthermore, we have proposed an architecture that allows performing RE at run-time. The purpose of the planned research is to combine and extend our recent work and to come up with a tool-based solution, which involves end-users in realizing self-adaptive services. Our research objectives include to continuously capture, communicate and analyze end-user needs and feedback in order to provide a tailored solution. [Contribution] In this paper we give a preview on the planned work. After reporting on our recent work we present our research idea and the research objectives in more detail
Mobile technologies to enable users' informed decisions
Full text linkThe significant wide impact of mobile technologies (e.g., smartphones, tablets) and the difficulty of mastering their complexity (due to factors like constant emergence and evolution) pose new challenges to many (if not all) software engineering disciplines. We particularly see these challenges when thinking of average citizens that carry out their daily activities in smart environments where mobile technologies and sensors installed provide many potential advantages to support them. Applications that could enable informed decision-making are currently beyond what software developers can provide. This position paper discusses challenges, and highlights current approaches available in order to support decision-making for thoughtful living. We present an initial version of a comprehensive framework to overcome the challenges identified and analyse which software engineering research lines may help to implement it. A motivating scenario is used to conduct the discussion
Foreword
No full textUsability and accessibility issues are common causes why software fails to meet user requirements. However, requirements engineers still focus on functional requirements and might ignore to also elicit system usability and accessibility requirements. Improving the usability and accessibility of a system in a later development stage is costly and time consuming. © 2012 IEEE

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
