Emotional and interpretive responses to three short stories were noted in two study populations of similar age: Qatari students in a post-highschool foundation program preparing to attend branch campuses of western universities located in Qatar, and American students, many of Mexican-American heritage, from a small college in a rural setting in South Texas. It has long been thought that reading literature from a foreign culture confers educational value on the reader; in this investigation the nature of that ‘value’ was placed under study. Written responses to quiz questions or assignments were used as data; responses critical of or affirming of character, setting, plot, and literary tropes were particularly noted. Our data show that readings from an author whose culture was similar to the reader’s created interest and urged both intellectual and affective types of understanding, such as remembering, grieving, healing, forgiving, and feeling pride. Readings from ‘classic’ literature presented in historical context strongly enabled critical discussion among students in a multicultural setting, since the author’s absence from the scene ‘allows’ free conversation about his or her work without fear of insulting the author’s culture. Readings by contemporary writers from outside the reader’s culture, or ‘multicultural literature’, may cause some readers to shy away from the challenge of understanding another culture or to voice stereotypes instead of seeking ideas. Readings from outsider cultures, however, and the affective distancing of ‘othering’, enable the well-prepared educator and student to discuss how culture patterns our lives.

Digital freight forwarder (DFF) start-ups and their associated business models have gained increasing attention within both academia and industry. However, there is a lack of empirical research investigating the differences between DFFs and traditional freight forwarders (TFF) and the impact of digital start-ups on incumbents' companies. In response, this study aims to examine the key business model characteristics that determine DFFs and TFFs and propose a framework illustrating the extent to which digital logistics start-ups influence incumbent logistics companies.

Based on the primary data gathered from eight interviews with experts from start-ups' and incumbents' logistics companies, as well as secondary data, the authors identify the main factors of DFFs start-ups that have an impact on TFFs and analyze the similarities and differences in regard to the business model components' value proposition, value creation, value delivery and value capture.

The results show that differences between DFFs and TFFs appear in all four business models' components: value proposition, value creation, value delivery and value capture. In particular, the authors identify three main factors that need to be considered when assessing the impact of DFFs on TFFs: (1) the company size, (2) the market cultivation strategy and (3) the transport mode.

This is one of the first studies to specifically examine the key business model differences between DFFs and TFFs and to propose a conceptual framework for understanding the impact of digital logistics start-ups on incumbent companies.

Laser sintering of polyamide lattice-based lightweight fairing components for subsequent racetrack testing requires a high quality and a reliable design. Hence, the purpose of this study was to develop a design methodology for such additively manufactured prototypes, considering efficient generation and structural simulation of boundary conformal non-periodic lattices, optimization of production parameters as well as experimental validation.

Multi-curved, sandwich structure-based demonstrators were designed, simulated and experimentally tested with boundary conformal lattice cells. The demonstrator’s non-periodic lattice cells were simplified by forward homogenization processes. To represent the stiffness of the top and bottom face sheet, constant isotropic and mapped transversely isotropic simulation approaches were compared. The dimensional accuracy of lattice cells and demonstrators were measured with a gauge caliper and a three-dimensional scanning system. The optimized process parameters for lattice structures were transferred onto a large volume laser sintering system. The stiffness of each finite element analysis was verified by an experimental test setup including a digital image correlation system.

The stiffness prediction of the mapped was superior to the constant approach and underestimated the test results with −6.5%. Using a full scale fairing the applicability of the development process was successfully demonstrated.

The design approach elaborated in this research covers aspects from efficient geometry generation over structural simulation to experimental testing of produced parts. This methodology is not only relevant in the context of motor sports but is transferrable for all additively manufactured large scale components featuring a complex lattice sub-structure and is, therefore, relevant across industries.
