Purpose To examine the strategic focus of shippers and transport providers (TPs) in reducing the environmental impact of transportation. Research questions: 1) To what extent are the green practices related to transportation described in literature being realised in practice by shippers and TPs? 2) How do shippers and TPs prioritise transportation compared to other initiatives for greening the sup

We develop a new scheme for the construction of explicit complex-valued proper biharmonic functions on Riemannian Lie groups. We exploit this and manufacture many infinite series of uncountable families of new solutions on the special unitary group SU(n). We then show that the special orthogonal group SO(n) and the quaternionic unitary group Sp(n) fall into the scheme. As a by-product we obtain

The compelling images and promises attached to autonomous drive vehicles can easily create an impression that one can speak of a radical distinction between a self-driving future and a manual-driving present. Yet today’s drivers can already refer to their everyday driving as being experienced as though on ‘auto-pilot’, in which they are able to drive their cars while lost in things such as daydrea

Two trends intersect in the present: rising temperatures and the rise of the far right. What happens when they meet? In recent years, the far right has done everything in its power to accelerate the heating: an American president who believes it is a hoax has removed limits on fossil fuel production. The Brazilian president has opened the Amazon and watched it burn. In Europe, parties denying the

Pantomime is a means of bodily visual communication that is based on iconic gestures that are not fully conventional. It has become a key element in many models of language evolution and a strong candidate for the original human-specific communicative system (Zlatev et al. 2020). Although pantomime affords successful communication in many contexts, it has some semiotic limitations. In this study,

For two-dimensional steady pure-gravity water waves with a unidirectional flow of constant favorable vorticity, we prove an explicit bound on the amplitude of the wave, which decays to zero as the vorticity tends to infinity. Notably, our result holds true for arbitrary water waves, that is, we do not have to restrict ourselves to periodic or solitary or symmetric waves.

We investigate the space–time picture of string evolution and hadron production in a fully string-based model for high energy collisions involving heavy-ions. We find that although the density of strings is quite large at the time of hadronization in a central heavy-ion collision, the initial overlap between them right after the collisions is not necessarily large. We also find that when including

Collagen is the main organic building block of musculoskeletal tissues. Despite collagen being their smallest load bearing unit, these tissues differ significantly in mechanical function and properties. A major factor behind these differences is their hierarchical organization, from the collagen molecule up to the organ scale. It is thus of high importance to understand the characteristics of each

Despite the importance of SMEs for innovation activity, questions remain concerning the determinants of their innovative performance and the role of different types of collaboration and partners. The present paper empirically analyzes the role played by different types of R&D collaborations in the persistence of SME innovative performance. We used a longitudinal database to identify all the Sw

Kan en silkeshandske vara en symbol för makt? I denna tänkvärda volym samlas en grupp namnkunniga historiker för att ge perspektiv på överlappande frågor kring genus, materialitet och politik. Genom historiska fallstudier som sträcker sig från 1500-talet och fram i modern tid utforskar författarna brännpunkter i företeelser som diplomati, kvinnors inflytande och tillskrivandet av betydelse hos förCan a silk glove be an expression of power? In this carefully curated volume, internation­ally renowned historians have come together to explore the interconnected perspectives of gender, materiality, and politics. As the authors elaborate on these topics, the volume offers contributions covering a period from the sixteenth century to the present day, investigating political culture and diplomacy,

Business angels are a vital source of capital for innovative start-up firms. However, many potentially attractive investment opportunities are rejected during the angel's decision-making process. Information asymmetry, risk and distrust in the relationship between the investor and the entrepreneur result in investment barriers. The concept of proximity has been proposed as a conceptual foundation

In this study of the effects of lead on the endocrine system, 77 secondary lead-smelter workers (i.e., 62 active and 15 retired) were compared with 26 referents. Lead concentrations were determined in plasma with inductively coupled plasma mass spectrometry (i.e., index of recent exposure), in blood with atomic absorption spectrophotometry, and in fingerbone with K x-ray fluorescence technique (i.

Habitat loss and population fragmentation pose severe threats to biodiversity and the survival of many species. Population isolation and the decline in effective population size lead to increased genetic drift and inbreeding. In turn, this reduces neutral diversity, and it also affects the genetic load of deleterious mutations. Here, we analyse the effect of such genomic erosion by designing a spa

Sherry Turkle in her groundbreaking book 'Alone Together' suggests that the Internet gives an illusion of togetherness while contributing to isolation. How might this play out in social movements on the Internet? Can social media bring people together? This research in progress explores the role of social media as a way to facilitate collective political action. It discusses the preliminary findin

We show that for a positive linear operator acting in ℓ2 and defined from anxn+1 + bn xn + an-1xn-1 its so-called Friedrichs and Krein extensions may be explicitly characterized by boundary conditions as n → ∞.
