Design thinking to enhance the sustainable business modelling process – A workshop based on a value mapping process

Sustainable business model innovation is an emerging topic, but only few tools are currently available to assist companies in sustainable business modelling. This paper works towards closing this gap by bringing together ‘design thinking’ and ‘sustainable business model innovation’ to refine the creative process of developing sustainable value propositions and improve the overall business modellin

Scaling up social businesses in developing markets

Most of the world's poor live in developing markets and face unmet needs in core areas such as education, health, energy, sanitation and financial services. This offers businesses a vast opportunity for growth as these economies emerge from low-income to middle-income status. Social businesses in particular address a social need while generating profits typically reinvested into the business itsel

Business model experimentation for sustainability

Business experimentation is a key avenue for accelerating change for sustainability. In contrast to experimentation in natural sciences, benefitting from controlled situations, business experimentation aims to explore the diverse possibilities that a business could create value from, or understand what works in which particular situations in a real life business context. While at present most popu

Towards a sufficiency-driven business model : Experiences and opportunities

Business model innovation is an important lever for change to tackle pressing sustainability issues. In this paper, 'sufficiency' is proposed as a driver of business model innovation for sustainability. Sufficiency-driven business models seek to moderate overall resource consumption by curbing demand through education and consumer engagement, making products that last longer and avoiding built-in

High-Mobility GaSb Nanostructures Cointegrated with InAs on Si

GaSb nanostructures integrated on Si substrates are of high interest for p-type transistors and mid-IR photodetectors. Here, we investigate the metalorganic chemical vapor deposition and properties of GaSb nanostructures monolithically integrated onto silicon-on-insulator wafers using template-assisted selective epitaxy. A high degree of morphological control allows for GaSb nanostructures with cr

Ballistic one-dimensional transport in InAs nanowires monolithically integrated on silicon

We present the monolithic integration and electrical characterization of InAs nanowires (NWs) with the well-defined geometries and positions on Si as a platform for quantum transport studies. Hereby, one-dimensional (1D) ballistic transport with step-like 1D conductance quantization in units of 2e2/h is demonstrated for NWs with the widths between 28 nm and 58 nm and a height of 40 nm. The electri

Ballistic One-Dimensional InAs Nanowire Cross-Junction Interconnects

Coherent interconnection of quantum bits remains an ongoing challenge in quantum information technology. Envisioned hardware to achieve this goal is based on semiconductor nanowire (NW) circuits, comprising individual NW devices that are linked through ballistic interconnects. However, maintaining the sensitive ballistic conduction and confinement conditions across NW intersections is a nontrivial

The changing landscape of work time reduction. The past and the future.

This chapter explains a historical overview of work organization strategies during the nineteenth and early twentieth century. It analyses the political and economic factors that affected the work time norms in the second half of the twentieth century, from around 1970 to 2000. The chapter discusses work organization in the changing world of low economic growth, decelerating increases in labour pr

‘Men just drink more than women. Women have friends to talk to’—Gendered understandings of depression among healthcare professionals and their implications

Little is known about how gendered understandings of patients can inform professionals’ discretionary actions and decisions to include or exclude in clinical practice. Using Connell's poststructuralist perspectives on gender as an analytic framework, this article aims to investigate how professionals’ articulations of depression are framed by signs of masculinity and femininity, and how these artiLittle is known about how gendered understandings of patients can inform professionals’ discretionary actions and decisions to include or exclude in clinical practice.

Jupiter Analogs Orbit Stars with an Average Metallicity Close to That of the Sun

Jupiter played an important role in determining the structure and configuration of the Solar System. Whereas hot-Jupiter type exoplanets preferentially form around metal-rich stars, the conditions required for the formation of planets with masses, orbits, and eccentricities comparable to Jupiter (Jupiter analogs) are unknown. Using spectroscopic metallicities, we show that stars hosting Jupiter an

Evolution and systematics of polyploid Nigritella (Orchidaceae)

Members of the orchid genus Nigritella are widespread in European mountains, but species circumscriptions and evolutionary patterns in the genus are subjects to conflicting opinions. We analyzed a representative material of Nigritella for differentiation at nuclear and plastid marker loci. In agreement with predictions from embryological studies, diploid members of Nigritella are sexual and mostly

Twelve fundamental life histories evolving through allocation-dependent fecundity and survival

An organism's life history is closely interlinked with its allocation of energy between growth and reproduction at different life stages. Theoretical models have established that diminishing returns from reproductive investment promote strategies with simultaneous investment into growth and reproduction (indeterminate growth) over strategies with distinct phases of growth and reproduction (determi

Perceptions of a mobile health intervention for community case management in Malawi : Opportunities and challenges for health surveillance assistants in a community setting

Background Improved availability of mobile phones in low- and middle-income countries (LMICs) offer an opportunity to improve delivery of Community Case Management (CCM). Despite enthusiasm for introducing mHealth into healthcare across LMICs, end-user attitudes towards mHealth solutions for CCM are limited. We aimed to explore Health Surveillance Assistants’ (HSAs) perceptions of the Supporting L

Bigeminal sandwiches galore

A long run of PVCs “sandwiched” in between the sinus beats resulting in an almost doubling of the heart rate—interpolated PVCs in bigeminy—is described. This case illustrates three interesting aspects of interpolated PVCs. Although they are not uncommon, long runs of interpolated PVCs in bigeminy are rare findings. In this case, the arrhythmia had a duration of 3 minutes. Second, it illustrates th
