Industrial Context

3D printing or additive manufacturing (AM) (in the industrial context) is an innovative, as opposed to subtractive, technology, bringing new opportunities and benefits to the spare part supply chain (SPSC). The aim of this work is to capture the views of the stakeholders at the end of the chain, extruding factors that will benefit the end-user and the factors that are likely to be an obstacle, by employing the questionnaire method. Company objectives regarding spares (cost reductions, improvement of services, space reduction) have been prioritized differently by the stakeholders. The most important barriers according to the participants are the quality assurance of the spare parts made by the new technology followed by the know-how and skills of staff. Other views such as suitable parts are suggested. The practical value of this work, in addition to assessing the readiness of the industry, is that it provides guidance for the successful implementation of AM in the maritime industry.

Here we contemplate the future and look also back to see where we have arrived. Art has responded to the ever-increasing presence of images available to people everywhere by maintaining its authenticity and originality. The proliferation of images in newspapers, magazines, books, posters and postcards has deeply influenced people and increased the number of images around them. Next the television, videos and movies introduced moving images and further accelerated this process. This whole phase has taken roughly two hundred years. More recently, the digitizing and Internet together have further made the spreading of images much easier and the quality of copying and receiving images gets all the time better. Meanwhile, the cost of reproducing images has drastically decreased. After this I will cover the present and future trends in art market and new ways of creating visual art and marketing it. There are some people who early on started to wonder whether authenticity really matters any more. My answer is that it matters more than ever and that art is still going strong.

PurposeThe purpose of this study is to evaluate the comprehensiveness of sustainability reporting in higher education institutions.Design/methodology/approachThis study adopts a university sustainability rating framework and uses it to evaluate the comprehensiveness of sustainability reporting in higher education institutions.FindingsThe results of the study demonstrate that notwithstanding growing concerns over sustainability issues; higher education institutions have been slow to adopt sustainability reporting practices including publishing consistent and periodic reports, receiving third-party assurance and integrating sustainability reporting into university’s sustainability management systems.Research limitations/implicationsThe results of the study suggest that the quality of sustainability reporting varies quite significantly, and important dimensions such as education and outreach programs are ill-treated in universities’ sustainability reports. The quality presents a tremendous challenge for sustainability reporting as more organizations are joining the sustainability reporting process, the quality would become a differentiator and competitive advantage, the study concludes. Two main limitations were identified. First, the number of reports examined were limited and are not representative of all higher education institutions. Second, data from other sources, like websites, were not factored in the analysis, as the study focuses on evaluating the comprehensiveness of sustainability reporting in higher education institutions.Practical implicationsThe results provide useful insights into comprehensiveness (one aspect of quality of sustainability reporting) in higher education institutions and help to better navigate the future trends in sustainability reporting practices of universities.Originality/valueSustainability reporting is well established in the corporate environment; however, the extent to which it has been adopted and its quality in universities remains relatively unexamined. The study attempts to fill the research gap in the quality of sustainability reporting (comprehensiveness) in higher education institutions to better navigate the future trends in sustainability reporting practices of universities.

The Future

This work presents the review of locomotives and the future of railway automotive power in Africa. Locomotives down time on account of inadequate spare parts still remains a challenge in African. It is thus, imperative to review the locomotives in African, to establish the current capabilities as well as provide recommendations to bridge the gaps and its extrapolated trends in future. Firstly, the comparison factors were track length, electrified rails, number of locomotives and yearly passengers on each of Egypt, Ghana, Kenya, Nigeria, South Africa and Zambia rails. Secondly, the focus was on engine parameters from literatures and maintenance logbooks of locomotives. From available data, it was found that South Africa and Egypt have more advanced rail system than the rest four selected countries. It was also found that additive manufacturing, 3D printing, ductile cast iron and die-forging can be used to produce the engine body for diesel engine using steel and aluminum alloys while aluminum silicon and tin doped with copper are good for reciprocation mechanisms. And finally, increased reliability of locomotives can be guided by an engine selection matrix, while use of renewable and energy hybridization are needed to meet the expansion of railroads in Africa.
