Abstract Advances in sociophonetic research resulted in features once sorted into discrete bins now being measured continuously. This has implied a shift in what sociolinguists view as the abstract representation of the sociolinguistic variable. When measured discretely, variation is variation in selection: one variant is selected for production, and factors influencing language variation and change are influencing the frequency at which variants are selected. Measured continuously, variation is variation in execution: speakers have a single target for production, which they approximate with varying success. This paper suggests that both approaches can and should be considered in sociophonetic analysis. To that end, I offer the use of hidden Markov models (HMMs) as a novel approach to find speakers’ multiple targets within continuous data. Using the lot vowel among whites in Greater St. Louis as a case study, I compare 2-state and 1-state HMMs constructed at the individual speaker level. Ten of fifty-two speakers’ production is shown to involve the regular use of distinct fronted and backed variants of the vowel. This finding illustrates HMMs’ capacity to allow us to consider variation as both variant selection and execution, making them a useful tool in the analysis of sociophonetic data.

Supporting Tool

Program assertions have been recognized as a supporting tool during software development, testing, and maintenance. Therefore, software developers place assertions within their code in positions that are considered to be error prone or that have the potential to lead to a software crash or failure. Similar to any other software, programs with assertions must be maintained. Depending on the type of modification applied to the modified program, assertions also might have to undergo some modifications. New assertions may also be introduced in the new version of the program, while some assertions can be kept the same. This paper presents a novel approach for test case prioritization during regression testing of programs that have assertions using fuzzy logic. The main objective of this approach is to prioritize the test cases according to their estimated potential in violating a given program assertion. To develop the proposed approach, we utilize fuzzy logic techniques to estimate the effectiveness of a given test case in violating an assertion based on the history of the test cases in previous testing operations. We have conducted a case study in which the proposed approach is applied to various programs, and the results are promising compared to untreated and randomly ordered test cases.

Systems Intelligence

In their role as problem solvers, engineers are expected to take responsibility for the grand societal challenges that require technical expertise and innovation. This urges them to broaden their horizon from the traditional, deeply technological world view to one that examines the surrounding globe with empathy and social responsibility. Such a call for systems intelligence necessitates a novel approach to engineering education to allow students to practice systemic capabilities. As methodology, life-philosophical pedagogy was experimented with in an English language course that was integrated with the Philosophy and Systems Thinking lecture series. Such pedagogy deviates from conventional methodology in that instead of focusing on correcting deficiencies and filling competence gaps, it takes a midwife approach and recognizes the potential in individuals and delivers the abundance in them. The principles of positive psychology and frameworks of socio-emotive intelligence guide the reflective workout in the course, catalyzing, stimulating and rooting new thinking. Ultimately the course promotes self-growth, intentional change and overall life management, while allowing students to rehearse various interpersonal skills relevant for industrial tasks.

Cloud Learning Environments (CLEs) have recently emerged as a novel approach to learning, putting learners in the spotlight and providing them with the cloud-based tools for building their own learning environments according to their specific learning needs and aspirations. Although CLEs bring significant benefits to educators and learners, there is still little evidence of CLEs being actively and effectively used in the teaching and learning process. This chapter addresses this issue by introducing a European initiative called weSPOT (Working Environment with Social, Personal and Open Technologies for Inquiry-based Learning) for supporting and enhancing inquiry-based learning in STEM education via a cloud-based inquiry toolkit. The chapter presents evidence of using this toolkit within a case study that investigates how a secondary education community of students / co-learners selects information sources on the web and identifies factors associated with the reliability of information sources during their collaborative inquiry (co-inquiry) project in online environments.

The starting point for this article is an artist-led practice developed by choreographer João Fiadeiro during the past two decades, which has been designated as "Composition in Real Time" (CTR). The interesting point about this methodology is that it has been applied in performance composition and in arts education by its author himself; but also in such diverse fields as anthropology, sociology, neurosciences, and economy by scientists and academics in collaboration with Fiadeiro. The authors of this article have conducted a long-lasting case study on the artistic process of Fiadeiro in the framework of an ERC-funded interdisciplinary arts and cognition project. We present our resulting novel approach to researching contemporary dance work through the creation and production of animated infographic films. Along with leading PaR theorists we argue that the utilization of adequate artistic techniques and methods in academic research can successfully reveal how unique creative ideas and conceptual structures come into being in the creative processes of today's contemporary artists. The article discusses specific excerpts of the provided animated infographic films to show how we digitally re-constructed Fiadeiro’s conceptual and imaginative universe, and how our findings can address both an academic and interested lay audience.
