Most studies of fashion and fads focus on objects and practices that once were popular. We argue that limiting the sample to such trajectories generates a selection bias that obscures the underlying process and generates biased estimates. Through simulations and the analysis of a data set that has previously not been used to analyze the rise and fall of cultural practices, the New York Times text archive, we show that studying a whole range of cultural objects, both popular and less popular, is essential for understanding the drivers of popularity. In particular, we show that estimates of statistical models of the drivers of popularity will be biased if researchers use only trajectories of those practices that once were popular. © 2015 Denrell, Kovács.

In this paper, we review recent developments in the field of outsourcing and offshoring and the implications for engineering management. We examine three aspects involved in outsourcing and offshoring, namely, sourcing models, coordination, and value extracted from outsourcing projects. We conclude that additional research is needed on recent trends in outsourcing and the impact of such change process on the practice of engineering management. © 2011 IEEE.

New product development (NPD) success depends on the capacity of different functions to effectively collaborate. In particular, while recent studies have highlighted the importance of marketing and design working together, research suggests this relationship is often fraught with conflict due to different "thought worlds." However, empirical research also identifies that the solution lies not in reducing the psychological distance between the two functions, but in the sensemaking practices used by designers and marketers to expand each other's understanding of the potential NPD solution. This process is known as resourceful sensemaking, and it refers to practitioners' capacity to transform knowledge with the aim of expanding each other's horizons to ensure better team outcomes. Drawing on 71 interviews with designers and marketers in Australia and New Zealand, we examine how each function strategically deploys knowledge of the other to improve NPD outcomes. Building on the sensemaking literature, we demonstrate that while still drawing on different thought worlds, the inputs of both designers and marketers are necessary for effective NPD. We also identify that both are capable of creating a common framework of meaning through three resourceful sensemaking practices: exposing, co-opting, and repurposing. Moreover, we identify the need for resourceful sensemaking that results in horizon-expanding discourse among those involved in NPD. These practices are found to enable marketers and designers to expand the range of considerations and inputs into NPD; help organizations reconcile either/or dualisms; and lead them to identify unmet consumer needs, which result in the creation of innovative products. This paper thereby advances understanding of interfunctional coordination in NPD, integration of design into NPD, and sensemaking more broadly. © 2016 Product Development & Management Association.

In rural areas of developing countries, electrification projects with photovoltaic systems were conceived as pilot projects with the implementation of a limited number of systems. After considerable financial support from international donors, photovoltaic systems were often quickly abandoned few years after their installation. Using micro-credit institutions in the energy sector or implementing small utilities with a fee-for-service model is now considered as two desirable options to create a dynamic self-sustained market for solar home systems.South Africa launched in 1999 an ambitious off-grid solar electrification programme with fee-for-service concessions. Operating as small-scale utilities, fee-for-service concessions have facilitated the implementation on a large scale of solar home systems and solved the issue of high up-front cost and of long-term maintenance.This paper focuses on operational and design issues linked to the implementation of fee-for-service concessions. Even in a challenging institutional context, some South African operators seem almost able to reach their break-even point. The case of one concessionaire is detailed and serves as a basis for a discussion on the benefits and difficulties linked to the fee-for-service model and on the potential for replication. © 2011 International Energy Initiative.

What is the most efficient way of lacing a shoe? Mathematically speaking, this question concerns the structure of certain special cases of the bipartite travelling salesman problem (BTSP). We show that techniques developed for the analysis of the (standard) TSP may be applied successfully to characterize well-solvable cases of the BTSP and the shoelace problem. In particular, we present a polynomial time algorithm that decides whether there exists a renumbering of the cities such that the resulting distance matrix carries a benevolent combinatorial structure that allows one to write down the optimal solution without further analysis of input data. Our results generalize previously published well-solvable cases of the shoelace problem. © 2014 Springer International Publishing.
