Are Born Globals really different from firms with other start-up histories? We address this question based on a unique longitudinal data set that tracks all Danish manufacturing start-ups founded between 1994 and 2008 (23,201 firms). This novel application of register data allows us to provide the first detailed account of Born Globals compared to proper control groups of other start-ups. Chiefly we investigate firm performance, which in turn permits interference on socioeconomic impact. We find that the occurrence of BGs is not specific to certain sectors, nor does their frequency change in light of rapid ICT progress. However, we find that Born Globals have significantly higher turnover and employment levels as well as job growth rates. Moreover, they show a considerably wider market reach, but little to no productivity advantage compared to firms with less or later internationalization. Thus, Born Globals are special in some but not all aspects.

Synchrotron X-ray tomographic microscopy (XTM) has been used to observe in situ damage evolution in unidirectional flax fibre yarn/polypropylene composites loaded in uniaxial tension at stress levels between 20% and 95% of the ultimate failure stress. XTM allows for 3D visualization of the internal damage state at each stress level. The overall aim of the study is to gain a better understanding of the damage mechanisms in natural fibre composites. This is necessary if they are to be optimized to fulfil their promising potential. Three dominating damage mechanisms have been identified: (i) interface splitting cracks typically seen at the interfaces of bundles of unseparated fibres, (ii) matrix shear cracks, and (iii) fibre failures typically seen at fibre defects. Based on the findings in the present study, well separated fibres with a low number of defects are recommended for composite reinforcements.

Purpose The purpose of this paper is to investigate the nascent market settings from a business model innovation perspective with the research questions: How do incumbents and start-ups make sense of an emerging technology through business model design in a nascent market setting, and how does business model choice influence firm performance? Design/methodology/approach The authors have tracked the development of four case companies in the nascent electric vehicle market from 2009 to 2018 and have conducted interviews and analyzed the archival data. Findings The authors propose a typology of business model choices and performance where the four types of business models distinguish themselves by how the companies innovate or imitate the value proposition of the current industry as well as how they innovate or imitate the business model archetype. In accordance with these different business model choices, the actors express different logics behind their new to the product market space business model choice. These logics represent different understandings of technology potential, customer needs as well as potential for value capture and contribute to and limit the translation of emerging technologies into dominant designs in diverse ways. Originality/value The business model is conceived as a focusing device that can be used to identify market applications for emerging technologies. As new disruptive technologies often require a new to the product market space business model, literature has in recent years put a premium on business model innovation. However, the linkages between emergent technologies and the choice of a novel business model are under investigated especially in relation to how business model choice affects business performance in nascent market settings. This paper aims at filling this gap.

A new approach is proposed for measuring the J integral (and thus the fracture resistance) of interface cracks in multiply laminates. With this approach the J integral is found from beam curvatures and applied moments. Knowledge of ply layup and stiffness is not required. In order to test the accuracy of the proposed approach, double cantilever beam specimen loaded with uneven bending moments (DCB-UBM) specimens were tested and analysed using the curvature approach and a method based on laminate beam theory. Beam curvatures were determined using a configuration of strain gauges. Good agreement was obtained between the two approaches.
