PurposeIndustry 4.0 is predicted to be a game-changer, revolutionizing commercial and manufacturing practices through improved knowledge utilization and efficiencies. The barriers however, are significant, and the construction industry remains notoriously slow to take up innovations. This study reviews the research work in Industry 4.0 as it relates to construction, and examines a leading UK-based construction firm to ascertain the prognosis for Industry 4.0 roll-out in terms of the impediments and opportunities.Design/methodology/approachA multistage mixed philosophies and methods approach was adopted for this study. First, an interpretivist epistemological lens was used to synthesise extant literature as a means of contextualizing the present study. Second, an empirical case study using a post-positivist stance and inductive reasoning was conducted to explore practitioner acceptance of Industry 4.0 in the UK construction context.FindingsFindings from the literature review indicate studies in Industry 4.0 to be a relatively new phenomenon, with developed countries and Germany in particular leading in the field. The range of opportunities are many, but so too are the barriers to enablement. Findings from the case study provide real-world corroboration of the review; practitioners are sanguine about Industry 4.0's potential to reinvigorate the construction industry, but also note that implementation remains curtailed by residual managerial practices dependent on ‘human interaction’. At present, much of the focus of industry practitioners is on the implementation of building information modelling (BIM), often at the expense of other more advanced technologies within Industry 4.0.Originality/valueResearch in Industry 4.0 is limited, with the emphasis being on technology application. This paper, by contrast, maps the totality of work carried out so far and presents an assessment of Industry 4.0's progression, potential and degree of uptake within the UK construction industry.

Purpose – This paper aims to compare the reflow and Zn diffusion behaviors in Sn-Zn and Sn-8.5Zn-0.5Ag-0.01Al-0.1Ga (5E) solders during soldering on a Ni/Cu substrate under infrared (IR) reflow. The study proposes a model on the effect of various elements particularly Zn diffusion behavior in the solders on the formation of intermetallic compounds (IMCs). Design/methodology/approach – The melting activities of two solders near their melting points on copper substrates are visualized in an IR reflow furnace. Reflowed solder joints were analyzed using scanning electron microscope and energy dispersive X-ray spectroscopy. Findings – Reflow behaviors of the solders are similar. During melting, solder balls are first merged into each other and then reflow on the substrate from top to bottom. Both solders show a reduced amount of Zn in the solder. Theoretical calculations demonstrate a higher Zn diffusion in the 5E solder; however, the amount of Zn actually observed at the solder/substrate interface is lower than Sn-9Zn solder due to the formation of ZnAg3 in the solder. A thinner IMC layer is formed at the interface in the 5E solder than the Sn-Zn solder. Research limitations/implications – The present work compares the 5E solder only with Sn-Zn solder. Additional research work may be required to compare 5E solder with other solders like Sn-Ag, SnAgCu, etc. to further establish its practical applications. Practical implications – The study ascertains the advantages of 5E solder over Sn-Zn solder for all practical applications. Originality/value – The significance of this paper is the understanding of the relation between reflow behavior of solders and reactivity of different elements in the solder alloys and substrate to form various IMCs and their influence on the formation of IMC layer at solder/substrate interface. Emphasis is provided for the diffusion behavior of Zn during reflow and respective reaction mechanisms.

Purpose – The purpose of this paper is to examine the utility of a redesigned course assessment in a required, introductory Master of Public Health (MPH) course to demonstrate competency achievement through practical application. School of public health curricula are informed by competency-based education (CBE) to prepare students for the field. This is a challenge in introductory courses as traditional assessments do not translate into practical application of knowledge. Design/methodology/approach – This retrospective post-test-only evaluation examined a practice-based, multi-disciplinary assessment utilized in Fall 2014 (n = 63 students). Web-based surveys were administered three months after the course to participating students (n = 33), the teaching team or teaching teams (n = 7) and organization representatives (n = 3) to evaluate the utility of the assessment. Questions were analyzed descriptively using chi-square tests, where applicable responses were compared across groups. Findings – Results indicate that a practice-based assessment in an introductory MPH course may enhance student learning by fostering deeper appreciation and application of course content while more closely reflecting the collaborative, multi-disciplinary and problem-solving nature of practice. The assessment may also increase the depth of competency achievement and career preparedness. Practical implications – Institutions that are guided by CBE, train students for multi-disciplinary practice and are impacted by the changing landscape of the field may want to consider course assessments that mimic practice to best prepare students. Originality/value – Course assessments should be evaluated to ensure they appropriately measure competency achievement. This evaluation provides multiple perspectives on the process and outcome of a practice-based course assessment.
