Scope Management of Non-Functional Requirements

In order to meet commitments in software projects, a realistic assessment must be made of project scope. Such an assessment relies on the availability of knowledge on the user-defined project requirements and their effort estimates and priorities, as well as their risk. This knowledge enables analysts, managers and software engineers to identify the most significant requirements from the list of requirements initially defined by the user. In practice, this scope assessment is applied to the Functional Requirements (FRs) provided by users who are unaware of, or ignore, the Non-Functional Requirements (NFRs). This paper presents ongoing research which aims at managing NFRs during the software development process. Establishing the relative priority of each NFR, and obtaining a rough estimate of the effort and risk associated with it, is integral to the software development process and to resource management. Our work extends the taxonomy of the NFR framework by integrating the concept of the "hardgoal". A functional size measure of NFRs is applied to facilitate the effort estimation process. The functional size measurement method we have chosen is COSMICFFP, which is theoretically sound and the de facto standard in the software industry

The learning approaches of A level history and geography students analysed: a report from a sixth form college

This paper sought to explore how students in History and Geography approach learning. The research involved GCE A Level students in the Sixth Form College sector, in which they responded to a structured questionnaire that was drawn from the literature on self-regulated learning. The key areas for investigation revolved around motivation, self-efficacy, fear of failure and reflection. The data was analysed according to ability range with analysis undertaken between the A*-B range and those students below in the DE range. The conclusion suggests students adopt a range of approaches, some determined by their innate ability but others by more practical concerns such as the chances of success or the value of the activity. Importantly, the research also identified some common approaches adopted by students of History and Geography that challenge Kolb's views of subject disciplines divides

Dancing to the Partisan Beat: A First Analysis of Political Communication on TikTok

TikTok is a video-sharing social networking service, whose popularity is increasing rapidly. It was the world's second-most downloaded app in 2019. Although the platform is known for having users posting videos of themselves dancing, lip-syncing, or showcasing other talents, user-videos expressing political views have seen a recent spurt. This study aims to perform a primary evaluation of political communication on TikTok. We collect a set of US partisan Republican and Democratic videos to investigate how users communicated with each other about political issues. With the help of computer vision, natural language processing, and statistical tools, we illustrate that political communication on TikTok is much more interactive in comparison to other social media platforms, with users combining multiple information channels to spread their messages. We show that political communication takes place in the form of communication trees since users generate branches of responses to existing content. In terms of user demographics, we find that users belonging to both the US parties are young and behave similarly on the platform. However, Republican users generated more political content and their videos received more responses; on the other hand, Democratic users engaged significantly more in cross-partisan discussions.Comment: Accepted as a full paper at the 12th International ACM Web Science Conference (WebSci 2020).

Report on the Information Retrieval Festival (IRFest2017)

The Information Retrieval Festival took place in April 2017 in Glasgow. The focus of the workshop was to bring together IR researchers from the various Scottish universities and beyond in order to facilitate more awareness, increased interaction and reflection on the status of the field and its future. The program included an industry session, research talks, demos and posters as well as two keynotes. The first keynote was delivered by Prof. Jaana Kekalenien, who provided a historical, critical reflection of realism in Interactive Information Retrieval Experimentation, while the second keynote was delivered by Prof. Maarten de Rijke, who argued for more Artificial Intelligence usage in IR solutions and deployments. The workshop was followed by a "Tour de Scotland" where delegates were taken from Glasgow to Aberdeen for the European Conference in Information Retrieval (ECIR 2017

How pluralistic is the research field on adult education? Dominating bibliometrical trends, 2005-2012

What the field of adult education research is and how it can be described has been a debated issue over the decades. Several scholars argue that the field today is heterogeneous, borrowing theories and methods from a range of disciplines. In this article, we take such statements as a starting point for empirical analysis. In what ways could it be argued that the field is pluralistic rather than monolithic; heterogeneous rather than homogenous? Drawing on bibliographic data of the top cited articles in three main adult education journals between 2005 and 2012, we illustrate how the citation patterns have tendencies of homogeneity when it comes to the geographical country of authorship, since the USA, UK, Australia and Canada dominate, as well as the research methods adopted, since qualitative approaches have near total dominance. Furthermore, there is a tendency to adopt similar theoretical approaches, since sociocultural perspectives, critical pedagogy and post-structuralism represent more than half of the articles in our sample. At the same time, the results of our analysis indicate signs of scholarly pluralism, for instance, in terms of authorship, since both early career researchers and established researchers are represented among the top cited publications. We conclude the article by arguing that empirical analysis of publication and citation patterns is important to further the development of reflexivity within the field, not least for early career researchers, who might benefit from knowledge about what has been recognized among peers as worth citing in recent times.
