Designing Sustainable Energy for All. Sustainable Product-Service System Design Applied to Distributed Renewable Energy
This book aims to share its contents with everyone who is interested to know more about designing Sustainable Product-Service System (S.PSS) applied to Distributed Renewable Energy (DRE), towards sustainable energy access for All. The book is organised to provide an overview of the topic and as well to support the design in practice. For this reason, the book includes strategies and guidelines, as well as a collection of case studies of Sustainable Product-Service System (S.PSS) applied to Distributed Renewable Energy (DRE) solutions. Additionally, are presented the method and support tools for designers
Scenario-based requirements elicitation for user-centric explainable AI
Explainable Artificial Intelligence (XAI) develops technical explanation methods and enable interpretability for human stakeholders on why Artificial Intelligence (AI) and machine learning (ML) models provide certain predictions. However, the trust of those stakeholders into AI models and explanations is still an issue, especially domain experts, who are knowledgeable about their domain but not AI inner workings. Social and user-centric XAI research states it is essential to understand the stakeholderâs requirements to provide explanations tailored to their needs, and enhance their trust in working with AI models. Scenario-based design and requirements elicitation can help bridge the gap between social and operational aspects of a stakeholder early before the adoption of information systems and identify its real problem and practices generating user requirements. Nevertheless, it is still rarely explored the adoption of scenarios in XAI, especially in the domain of fraud detection to supporting experts who are about to work with AI models. We demonstrate the usage of scenario-based requirements elicitation for XAI in a fraud detection context, and develop scenarios derived with experts in banking fraud. We discuss how those scenarios can be adopted to identify user or expert requirements for appropriate explanations in his daily operations and to make decisions on reviewing fraudulent cases in banking. The generalizability of the scenarios for further adoption is validated through a systematic literature review in domains of XAI and visual analytics for fraud detection
Employability Skill Development of Mechanical Engineering Students Through Project Based Learning in Vocational High School in South Sulawesi
Abstract: Embedding employability skills in learning requires a learning model that allows effective in improving employability skills of students Learning model that if able to meet these expectations is project based learning. This study aims to determine the contribution of project based learning to employability skills of students of SMK Package Engineering Skills Engineering in South Sulawesi. This research uses quantitative approach with non experimental design with sample size 325 students. Data collection uses questionnaires to obtain data on project-based learning implementation and employability skills. The data of the research were analyzed by using descriptive analysis and regression analysis which previously conducted normality and linearity test. Based on the results of the research is known that the implementation of project based learning model contributes to the development of employability skill students of machining engineering SMK 59.8%

Botswanaâs Quest for Sustainability: Scope for Design Intervention
For the last three decades Industrial Designers have been blamed for designing for 'greed' and not for 'need'. The current mode of design practice is a reflection of the problems of Design, the Designers and the society. This paper looks at some of the paradoxes that Botswana has had to deal with in its quest for social sustainability through design intervention. The paper also outlines several contextual concepts and strategies that might address design needs of Botswana and how they impact on this burning issue. It stresses that design; designers and the society need redesign in pursuit of social sustainability
Design through storytelling
Plagiarism is one of the major challenges in undergraduate studentsâ written assignments. Against a background of general under preparedness of students entering higher education, poor academic literacy levels, limited knowledge about plagiarism and an increasing affinity among students towards visual learning resources, this paper reports on a research study that investigated the potential of digital storytelling as an alternative assessment method in a first year Industrial Design course, at a University of Technology, South Africa. In this course, Technology 1, digital storytelling was used for student assessment instead of a paper-based essay. Digital stories are usually short movie clips, created with off-the-shelf equipment and techniques, combining text, images, videos, music and narration. Drawing from the principles of authentic learning, the researchers investigated benefits and challenges of using digital stories as alternative assessment method. Qualitative methods of collecting data were used, which included focus group interviews with the students and in-depth interviews with lecturers. Findings of the study showed that digital storytelling promoted authentic learning, which led to high levels of student engagement with their studies and hence meaningful understanding of the subject matter. However, findings also revealed the importance of providing support to students in developing a high quality, polished end product. More research is needed to explore the potential of transferring this highly independent, student-led project into other disciplines

Hearing Impairment Among Children Referred to a Public Audiology Clinic in Gaborone, Botswana
Objective:. To describe and quantify hearing impairment among children referred to the audiology clinic in Princess Marina Hospital, a public referral hospital in Botswana. Methods:. In a retrospective case series, we reviewed medical records of children aged 10 years and younger whose hearing was assessed between January 2006 and December 2015 at the audiology clinic of Princess Marina Hospital in Gaborone, Botswana. Results:. Of 622 children, 50% were male, and median age was 6.7 years (interquartile range = 5.0-8.3). Hearing impairment was diagnosed in 32% of clinic attendees, comprising sensorineural (23%), conductive (25%), and mixed (11%) hearing loss, while 41% of children with diagnosed hearing impairment did not have a classification type. Hearing impairment was mild in 22.9%, moderate in 22.4%, severe in 19.4%, profound in 16.9%, and of undocumented severity in 18.4%. Children younger than 5 years were 2.7 times (95% confidence interval = 1.29-5.49; P = .008) more likely to be diagnosed with sensorineural hearing impairment compared with those older than 5 years. By contrast, children older than 5 years were 9.6 times (95% confidence interval = 2.22-41.0; P = .002) more likely to be diagnosed with conductive hearing loss compared with those under 5 years. Conclusion:. Hearing impairment was common among children referred to this audiology clinic in Botswana. Of those with hearing impairment, more than a third had moderate or severe deficits, suggesting that referrals for hearing assessments are not occurring early enough. Hearing awareness programs individually tailored to parents, educators, and health care workers are needed. Neonatal and school hearing screening programs would also be beneficial
