Walking meetings are a promising way to reduce unhealthy sedentary behavior at the office. Some aspects of walking meetings are however hard to assess using traditional research approaches that do not account well for the embodied experience of walking meetings. We conducted a series of 16 bodystorming sessions, featuring unusual walking meeting situations to engage participants (N=45) in a reflective experience. After each bodystorming, participants completed three tasks: a body map, an empathy map, and a rating of workload using the NASA-TLX scale. These embodied explorations provide insights on key themes related to walking meetings: material and tools, physical and mental demand, connection with the environment, social dynamics, and privacy. We discuss the role of technology and opportunities for technology-mediated walking meetings. We draw implications for the design of walking meeting technologies or services to account for embodied experiences, and the individual, social, and environmental factors at play. [less ▲]

Schumpeterian entrepreneurs are considered agents of innovation and technology transfer. However, to fulfill this role, they need entrepreneurial finance. From the perspective of digital identity, we examine the relationship between a Schumpeterian digital identity and venture capital (VC) funding. Because the VC industry celebrates innovative and visionary entrepreneurship, we posit that a founder’s digital identity as a Schumpeterian-type entrepreneur influences the venture’s chances of receiving VC funding. A quantitative analysis of the language used by 3313 founders in a large sample of Twitter messages, however, provides a mixed picture. While some dimensions of Schumpeterian entrepreneurship have a positive relationship with the acquisition of resources from VC firms (entrepreneurial vision and optimism), other dimensions seem to have no (uncertainty tolerance and rationality) or even a decreasing (achievement motivation) effect. The negative relationships observed can be explained by the particularities of the VC business model, which does not align with Schumpeterian entrepreneurship in all respects. Our study contributes to research on Schumpeterian entrepreneurship, the financing of technology transfer, and the link between entrepreneurial digital identity and entrepreneurial finance. From a practical perspective, the results of our study demonstrate the limits of VC with regard to the financing of technology transfer and highlight the need for public funding through governmental VC or agencies for (disruptive) innovation.

Background: Internalizing behaviors are an indicator of children’s psychological and emotional development, predicting future mental disorders. Recent studies have identified associations between DNA methylation (DNAm) and internalizing behaviors. This prospective study aimed at exploring the associations between pace of biological aging and the developmental trajectories of internalizing behaviors. Methods: Participants were children from the Avon Longitudinal Study of Parents and Children (ALSPAC) cohort (N=974). Measures of DNA methylation were collected at birth, age 7 and ages 15-17. The pace of aging was estimated using the DunedinPoAm algorithm (PoAm). Internalizing behaviors reported by caregivers between ages 4 and 16 using the Strengths and Difficulties Questionnaire. To explore heterogeneity in the association between PoAm and internalizing behaviors we use Poisson quantile regression in cross-section heterogeneity and longitudinal latent class analysis over the childhood and adolescence. Results: Internalizing behavior trajectories were identified: low-risk, childhood limited, late onset and early onset (persistent). Accelerated aging at birth was negatively associated with internalizing behaviors in early childhood but positively correlated during adolescence. Higher PoAm at birth increased chance of low-risk profile, while decreasing likelihood of childhood limited trajectory. PoAm at age 15 was negatively associated with childhood limited profile and positively linked to late onset trajectories. Associations were larger at higher values of internalizing symptoms. Conclusions: The heterogeneity in the association between biological age acceleration and internalizing behaviors suggests a complex dynamic relationship, particularly in children with high or increased risk of adverse mental health outcomes.

This paper describes and evaluates a multidisciplinary, online research writing course for PhD students. First, we explain our course rationale and set-up. The core principles are personalised, self-regulated and peer learning, and the optimal use of class time. This is achieved through the following components: an e-coursebook developed in-house; tasks preparing students for the workshops; workshops; writing and reflection; peer review; and individual consultations. Next, we review participants’ feedback from course evaluation surveys. Many students liked the online format although most would prefer the peer review and discussion of theory to happen ‘offline’. A key finding for course efficacy is that students greatly valued working with their own examples in the workshops. They saw this and independent learning tasks as the greatest drivers of their writing development. They also benefited from multidisciplinary peer review. As regards the writing and reflection, all students chose to write on their own and the writing reflection tool was deemed ineffective. We furthermore discuss our (teachers’) perceptions of the affordances and challenges of this course format. On the one hand, it allows workshops to be devoted to collaborative tasks, reflection and data-driven learning. On the other hand, preparing such workshops is very time-consuming, while the multiple components and regular task submissions carry a heavy administrative burden. The paper concludes with how lessons learnt have been implemented into the current course configuration. [less ▲]

Implementing management innovation (MI) is a great challenge for international joint ventures (IJVs), specifically for those between multinational enterprises (MNEs) and local firms. Different multilevel factors have been shown in the international business literature to play a role in MI implementation within IJVs. In this paper, we add to this literature by showing that these factors do not act in isolation and that their interplay must be considered. To this aim, we draw on qualitative data from 35 CEOs and TMT members of five IJVs between European MNEs and Tunisian local firms. Overall, our study reveals that depending on the type of IJV, the multilevel factors playing a role in the implementation of MI are different [less ▲]

While working on a computer typically involves sitting for prolonged periods of time, sedentary work routines are associated with numerous health issues. To address this societal concern, existing solutions trigger physical activity as a break from work, rather than a part of it. In this research, we explore a vision for physically active ways of working, by transforming mundane digital tasks into physically active ones. As a research artifact and design exemplar, we present A2-I2, an innovative tangible system for sending emails. After loading their email onto a physical “letter” token, office workers must walk to a physical mailbox located in the office space. Understanding what design qualities influence the experience and acceptability of such systems is a necessary step toward the design of acceptably active interface interactions. We report on a preliminary user test with 8 participants. With this project, we aim to inspire future tangible and embodied systems addressing the timely issue of sedentary behavior at work.

This paper presents the design, simulation, and manufacturing of a right-hand circularly polarized antenna working in the frequency band 17.7-20.2 GHz with a beamwidth of 42.4$^\circ$ and 5.4$^\circ$ for the H-plane and E-plane, respectively. The presented antenna is part of a set of three antennas, two high-gain antennas, and, presented in this paper, a low directive antenna used for reception. The application we describe in this paper combines the radio-frequency signals obtained from the O3b satellite constellation, using three antennas to apply path diversity later to reconstruct the original signal. Moreover, using an antenna with a beamwidth in one plane allows receiving two satellite signals at the same time, increasing by 3 dB the overall gain. The wide-band capabilities of the antenna are obtained using aperture coupling. In particular, the circular polarization of the antenna is generated using a truncated corner square patch. Further, a metasurface is placed at the top to enhance the axial ratio. Importantly, the simulation results obtained using CST Microwave Studio show that the antenna has a reflection coefficient below -10 dB and an axial ratio below -3 dB in the intended frequency range.

This paper presents a frequency selective surface design and simulation using intertwined triangular structures. It has been discovered that by using the proposed tessellated intertwined lattice, the reduction of the resonance frequency of a frequency selective surface can be improved by 22.58% compared with other triangular structures. Additionally, this structure is used as a MEFSS to improve the miniaturization of the structure and obtain a compact, angular stable band-pass filter. The simulations presented in this paper have been obtained using CST Microwave Studio. [less ▲]

Recently, Biryukov et al. presented a new technique for key recovery in differential cryptanalysis, called meet-in-the-filter (MiF). In this work, we develop theoretical and practical aspects of the technique, which helps understanding and simplifies application. In particular, we show bounds on MiF complexity and conditions when the MiF-enhanced attack may reach them. We present a method based on trail counting which allows to estimate filtering strength of involved rounds and perform consequent complexity analysis with pen and paper, compared to the computer-aided approach of the original work. Furthermore, we show how MiF can be combined with plaintext structures for linear key schedules, allowing to increase the number of attacked rounds or to reduce the data complexity. We illustrate our methods on block cipher families CHAM and KATAN and show best-to-date single-key differential attacks for these ciphers. [less ▲]

This special issue brings together research on lecture discourse and lecturer training that contributes to the design and delivery of EAP lecture listening and note-taking courses on the one hand and lecturer training (for English Medium Instruction) on the other. The internationalization of higher education has gone hand in hand with a continuing increase in English Medium Instruction (EMI) - the use of English as a language of instruction in countries where it is not an official language – as well as online lectures. This has led to lecturing contexts which are linguistically, communicatively, educationally and culturally complex. To support students and lecturers in respectively learning and teaching effectively in this multifaceted context, proposals are invited for articles that provide insights into issues with a clear relevance to EAP course provision, such as the following: • What are the linguistic, communicative or multimodal features of lectures (face-to-face or online)? • How does English L1 and non-L1 (EMI) lecture discourse differ? • How can EAP practitioners prepare students for lectures delivered by EMI lecturers? • How can we assess the linguistic, communicative and pedagogical skills needed for effective lecture comprehension or lecturing? • How can we support or train EMI lecturers to teach effectively in English? • How can we support or train EMI and L1 English lecturers to teach groups with heterogeneous English language skills as well as different language, educational and cultural backgrounds?
