Abstract
Purpose
Physical inactivity has a considerable negative impact on health. Physical activity has reduced partly due to workplace and lifestyle changes, causing people to spend more time in buildings and increasing sedentary behaviour. The purpose of this paper is to address a largely untapped opportunity for designers and managers to improve building users’ health by designing buildings that raise users’ Non-Exercise Activity Thermogenesis (NEAT) levels. In this research a conceptual model was developed to assess buildings’ performance in providing NEAT-promoting opportunities through building design features and management, in relation to building users’ propensity for NEAT behaviours.
Design/methodology/approach
The conceptual model was developed by a multi-disciplinary team of researchers and data to populate the model was obtained through a survey of 75 buildings in Jakarta (Indonesia).
Findings
The presented proof-of-concept shows that the model’s “meso-scale” approach to study physical activity and building design can lead to potential improvements of NEAT levels and physical activity in buildings.
Originality/value
The review of precedent models shows that this subject has been researched at micro-scale (i.e. detailed monitoring of individuals’ movement) and macro-scale (i.e. epidemiological studies of populations’ health). The presented model is original, as it explores a “meso-scale”(i.e. building scale) that is unique.

Abstract
Purpose
Understanding the supply network of construction materials used to construct shelters in refugee camps, or during the reconstruction of communities, is important as it can reveal the intricate links between different stakeholders and the volumes and speeds of material flows to the end-user. Using social network analysis (SNA) enables another dimension to be analysed – the role of commonalities. This is likely to be particularly important when attempting to replace vernacular materials with higher-performing alternatives or when encouraging the use of non-vernacular methods. This paper aims to analyse the supply networks of four different disaster-relief situations.
Design/methodology/approach
Data were collected from interviews with 272 displaced (or formally displaced) families in Afghanistan, Bangladesh, Nepal and Turkey, often in difficult conditions.
Findings
The results show that the form of the supply networks was highly influenced by the nature/cause of the initial displacement, the geographical location, the local availability of materials and the degree of support/advice given by aid agencies and or governments. In addition, it was found that SNA could be used to indicate which strategies might work in a particular context and which might not, thereby potentially speeding up the delivery of novel solutions.
Research limitations/implications
This study represents the first attempt in theorising and empirically investigating supply networks using SNA in a post-disaster reconstruction context. It is suggested that future studies might map the up-stream supply chain to include manufacturers and higher-order, out of country, suppliers. This would provide a complete picture of the origins of all materials and components in the supply network.
Originality/value
This is original research, and it aims to produce new knowledge.

Abstract
Purpose
The purpose of this paper is to test the efficacy of the concept of food miles that has proved so popular with the public as a means of assessing the sustainability of produce.
Design/methodology/approach
This paper uses data from a UK major food importer and retailer to correlate carbon emissions from transport, and transport‐related storage, with food miles by creating farm‐specific mode‐weighted emission factors.
Findings
The correlation is found to be poor for a wide range of products and locations and it is clear that the mode of transport is as important as the distance, with sourcing from parts of the Mediterranean resulting in emissions greater than those from the Americas.
Practical implications
It is concluded that it is difficult to justify the use of food miles when attempting to influence purchasing behaviour. Because of this result, processes and tools have been developed that relay information on true transport‐related carbon emissions to customers and bulk purchasers that allow them to make informed decisions.
Originality/value
This paper questions the value of using the concept of food miles as a driving force for changing purchasing behaviour by either the customer or the purchasing department of a retailer.

Abstract
An established company's primary performance measures may revolve around operational excellence: squeezing out ever‐greater volume, quality, and service at declining cost, say. New staircases [new product/ business line development efforts], by contrast, must create revenue where none yet exists. Profitability may be years away. Holding the leaders of a new staircase accountable for goals they cannot achieve is a sure way to kill the business, and misses the point: if a new staircase is growing well, it should be a net cash consumer. Its goal is not making a profit but meeting project milestones, and ultimately generating high revenue growth. By exempting such a staircase from standard performance measures and giving it a different target, managers can foster growth.
