Abstract The use of shipping containers for the transport of goods has become indispensable and a crucial factor for globalization by providing inexpensive and safe transport opportunities. It is expected that the number of globally operating containers will increase in the near future. Despite a high technical modernisation of the logistic chain, the container still faces a risk of damage at any time and any place within the transport chain. In principle, a container is taken out of service, when a damage is recognized. Different causes of damage exist and various types of damage could occur to the container, ranging from minor to substantial major ones that do not permit the continued proper use of the container. Thus, an individual decision on repair and maintenance (R&M) for each damaged container is necessary. Aside from technical aspects, it has to be decided from an economical perspective whether a repair should be performed. A profound decision should consider various criteria like, e.g., repair costs, lifespan of the container, future yields and possible sales price. Based on a regulatory, practical, and scientific view, this paper proposes a multi-criteria decision model for the economic decision on the R&M of a damaged container. Implemented in Microsoft Excel, this decision model is easily applicable. The user can deduce a first (limited) guidance for dealing with a respective damaged container based on its current state and general market conditions.

Abstract We survey the current state-of-the-art in (commercial) Product Data Management (PDM) systems. After identifying the major functions of PDM systems, we indicate various shortcomings of the current PDM technology. An important shortcoming is in the representation and use of functions. We review the functional representation literature in the context of PDM technology. Systems management aspects of an engineering project is also commented on. We believe these two areas are the next two challenges awaiting PDM technology in the near future.

In the near future, combustion engineers will shape the burner according to the flame, and not the opposite way anymore. In this contribution, this idea is explored with the help of additive manufacturing (AM). The focus is put on the design and the production of swirlers using advanced materials with the least possible efforts in terms of manufacturing. The material chosen for this study is Inconel 718. There are three motivations to this project. The first one is to design new shapes and assess these in comparison to conventional ones. The second motivation is to be able to manufacture them using additive manufacturing, and to gather know-how on selective laser melting. The third motivation is to elaborate a methodology involving engineering, research and education to promote — only if and when this is desirable — the production of series of premium parts such as high-end components of gas turbine combustor using AM. First-of-a-kind swirler shapes are explained and designed. These are unlikely to be produced using conventional manufacturing. They are then successfully produced in Inconel 718 using AM. The raw parts are directly submitted for testing with no surface post-processing. The paper states why at current state-of-the-art the raw surface quality still needs improvement, and highlights the benefits of the new swirler shape versus conventional.

Neuroscience joins the long history of discussions about aesthetics in psychology, philosophy, art history, and the creative arts. In this volume, leading scholars in this nascent field reflect on the promise of neuroaesthetics to enrich our understanding of this universal yet diverse facet of human experience. The volume will inform and stimulate anyone with an abiding interest in why it is that, across time and culture, we respond to beauty, engage with art, and are affected by music and architecture. The volume consists of essays from foundational researchers whose empirical work launched the field. Each essay is anchored to an original, peer-reviewed paper from the short history of this new and burgeoning subdiscipline of cognitive neuroscience. Authors of each essay were asked three questions: (1) What motivated the original paper? (2) What were the main findings or theoretical claims made?, and (3) How do those findings or claims fit with the current state and anticipated near future of neuroaesthetics? Together, these essays establish the territory and current boundaries of neuroaesthetics and identify its most promising future directions. Topics include models of neuroaesthetics and discussions of beauty, art, dance, music, literature, and architecture. The volume targets the general public; it also serves as an important resource for scientists, humanitarians, educators, and newcomers to the field, and it will catalyze interdisciplinary conversations critical to the maturation of this young field.

We are living in a world wherein there soon will be more mobile phone subscriptions than people. In 2000 there were less than a billion mobile subscriptions worldwide. Today, there are more than 6 billion. Accordingly, it is predicted by the World Bank that mobile subscription “will soon exceed that of the human population…as it is common in many countries for one person to own multiple SIM cards” (Rosen, 2012). The socio-economic effect of this rapid and expansive diffusion of mobile communication is being experienced more than understood. The focus of this chapter is to examine the emerging character of smartphone usage from both the user and marketing practitioner’s perspective. Specifically, from the consumer perspective, profiles of smartphone ownership and use patterns will be delineated. From the marketer’s and business practitioner’s perspectives, strategic and tactical marketing applications of smartphone technologies will be documented. In addition, speculation on the near future impact of emerging mobile technologies on consumer and practitioner applications will be addressed. The chapter concludes with analysis and discussion of the current state of mobile analytics and mobile measurement. Mobile analytics and mobile measurement have not evolved as rapidly as the proliferation of mobile devices. Measurement and analysis of data generated from mobile usage remains in its nascent state due to the technological challenges of multiple operating systems, devices, and carriers as well as the lack of standards for technology and advertising specifications.

: The current power cables IEC standards do not provide adequate recommendations for after-laying testing and diagnosis of offshore export and inter-array power cables. However the standards IEEE 400 and IEEE 400.4 recommend partial discharge monitored testing, e.g., by continuous or damped AC voltages (DAC). Based on the international experiences, as collected in more than 20 years at different power grids, this contribution focuses on the use of DAC for after-laying testing and diagnosis of submarine power cables both the export and inter-array cables. Higher risk of failure, long unavailability, higher repair costs, and maintenance costs imply that advanced quality control is becoming more important. The current state of the existing and drafting international standards are based on onshore experiences and not related to the actual serious problems experienced with failures on export up to 230 kV and inter-array cables up to 66 kV. The application of damped AC as a testing solution in this concern is specially discussed. The advantages of this testing technique, in combination with actual testing examples, show the findings on export and inter-array cables at offshore wind farms.

Shed Light

This conceptual paper is a future study aiming to shed light on the current state of higher education in the MENA region. The neoliberal agenda for higher education in the region presents a form of education that is commodified, corporatized and focused on STEM rather than on humanities. The paper further speculates on the state of higher education in the near future under the same ideology. As an alternative, the study proposes the implementation of Martha Nussbaum’s Capabilities Approach. This approach is capable of re-balancing the tipped scale in the commodification of higher education and will serve in developing well-rounded individuals. The Capabilities Approach can reform higher education through critical thinking, liberal education, and attention to diversity.

Abstract After closing public schools in early 2020 to slow the spread of Covid-19, attempts to provide continuity of education in Germany by means of digital tools faltered in variety of ways, with insufficient competence and inadequate technology leading to inequitable access and uneven implementation. Understanding how German teachers were caught unprepared in this time of crisis, especially in comparison with their European neighbors, requires an examination of their habitus as discussed by Bourdieu and Wacquant (1992) that accounts for their behaviors beyond existing models regarding technology acceptance. Drawing on existing sociological and media-related studies, this contribution will describe the attitudes of German teachers and educational decision-makers in light of their digital, cultural, and educational habitus to provide a partial explanatory account for the current state of affairs. It will show how traditional skepticism for innovation among teachers in general, and German teachers in particular, is reinforced by demographic and sociological characteristics of the German teacher population and the nature of German schooling. After describing extant conditions regarding digitally mediated educational experiences during the initial Covid-19 phase in Germany based on emerging data, this article will subsequently identify prospective issues in this area in the near future. While the transition to digital teaching and learning has the potential to bring about a number of challenges, early data suggests that a possibility of significant positive development may occur as well. Based on these indications, the article will conclude with implications for teacher professionalization going forward.
