    How software engineering research aligns with design science: A review

    Full text link
    Background: Assessing and communicating software engineering research can be challenging. Design science is recognized as an appropriate research paradigm for applied research but is seldom referred to in software engineering. Applying the design science lens to software engineering research may improve the assessment and communication of research contributions. Aim: The aim of this study is 1) to understand whether the design science lens helps summarize and assess software engineering research contributions, and 2) to characterize different types of design science contributions in the software engineering literature. Method: In previous research, we developed a visual abstract template, summarizing the core constructs of the design science paradigm. In this study, we use this template in a review of a set of 38 top software engineering publications to extract and analyze their design science contributions. Results: We identified five clusters of papers, classifying them according to their alignment with the design science paradigm. Conclusions: The design science lens helps emphasize the theoretical contribution of research output---in terms of technological rules---and reflect on the practical relevance, novelty, and rigor of the rules proposed by the research.Comment: 32 pages, 10 figure

    Engineering simulations for cancer systems biology

    Computer simulation can be used to inform in vivo and in vitro experimentation, enabling rapid, low-cost hypothesis generation and directing experimental design in order to test those hypotheses. In this way, in silico models become a scientific instrument for investigation, and so should be developed to high standards, be carefully calibrated and their findings presented in such that they may be reproduced. Here, we outline a framework that supports developing simulations as scientific instruments, and we select cancer systems biology as an exemplar domain, with a particular focus on cellular signalling models. We consider the challenges of lack of data, incomplete knowledge and modelling in the context of a rapidly changing knowledge base. Our framework comprises a process to clearly separate scientific and engineering concerns in model and simulation development, and an argumentation approach to documenting models for rigorous way of recording assumptions and knowledge gaps. We propose interactive, dynamic visualisation tools to enable the biological community to interact with cellular signalling models directly for experimental design. There is a mismatch in scale between these cellular models and tissue structures that are affected by tumours, and bridging this gap requires substantial computational resource. We present concurrent programming as a technology to link scales without losing important details through model simplification. We discuss the value of combining this technology, interactive visualisation, argumentation and model separation to support development of multi-scale models that represent biologically plausible cells arranged in biologically plausible structures that model cell behaviour, interactions and response to therapeutic interventions

    Case study evaluation of edible plants curriculum implemented in an elementary school, A

    2014 Summer.The main purpose of this study was to describe elementary teachers' attitudes and perceptions toward plant science. The secondary purpose was to create an edible plant curriculum as a vehicle for integrating STEM and 21st Century skills into Common Core Content. Results indicate that teachers and STEM coordinators did find the curriculum to be effective in teaching the interdisciplinary standard-based and inquiry based content and skills targeted. Additionally, the curriculum development process produced a hybrid design framework that facilitated the creation of life science content as a vehicle for integrating STEM into common core content. However, several significant barriers will need to be overcome with regard to the teachers', STEM coordinators' and administrators' perception that plant science and nutrition literacy are "special" content activities versus important STEM content

    Labs and Landscapes Virtual Reality: Student-Created Forest Conservation Tours for Informal Public Engagement

    The following exploratory convergent mixed-methods study examined graduate students’ experiences developing and facilitating 360º photo-based virtual reality (VR) tours titled Labs and Landscapes focused on forest conservation and climate change education, as well as tour impacts on public audiences. Graduate students in an agricultural and natural resources communication course at The University of Florida used 360º cameras, mobile devices, and online software to create VR tours about the UF/IFAS Austin Cary Research Forest. Then, the students guided public participants through the tours in three physical informal learning environments including a museum, brewery, and campus tabling site within the university community. Data collection included VR tour artifacts, audio recordings of students’ VR facilitation and discourse with the public, post-surveys of public participants’ tour impressions and climate change attitudes, and pre-/post-student reflections. Data sources were collected separately and mixed in interpretation. Results showed students increased their multimedia communication skills, knowledge of natural resource conservation, and confidence in communicating with public audiences. Additionally, survey results indicated public participants agreed the students successfully guided the tours, agreed it is important to learn about conservation and climate change, and had some disagreement with the statement that humans cannot prevent climate change
