Purpose In this paper, the prior research on virtual teams was reviewed to assess the state of the literature. The purpose of this paper is to determine why individuals prefer working in virtual teams (also termed liquid workers and part-time workers). Previous researchers have focussed on the benefits that organizations receive if they hire liquid workers, but to date, no research has been conducted to determine the perspective of these liquid workers. The various definitions of virtual teams are discussed and an integrative definition is proposed that suggests all teams may be defined in terms of their extent of virtualness. Design/methodology approach A systematic review of the literature on virtual teams was conducted. The data were collected from 12 informants. A thematic analysis was used to analyse the data. Findings Six main themes were identified, namely, pliability, opportunities, increased earnings, vigour, family and transportation. Research limitations/implications This study was conducted in a three-metropolitan city in India and warrants being extended to rural and international settings to gain additional insights and confirmation of the research findings. Practical implications It is suggested that organizations who recruit liquid workers will be in a position for substantial cost savings; this is because organizations usually make payment of liquid workers’ wages on an hourly basis. This will help the organizations to schedule the number of working hours depending on their needs. Originality/value The current study is novel as there is a paucity of research in identifying the factors behind working in the virtual community in India. This study presents the first research of its kind to the best knowledge of the author, and the findings will be valuable for companies who are looking for cost savings.

Energy Use Intensity

Purpose Vacation rental homes, in general, have different energy usage characteristics than traditional residential homes mainly because of the occupancy pattern that changes on a weekly basis. These homes, predominantly larger in size, offer a greater scope for energy savings also because of the wasteful habits of their seasonal occupants. The purpose of this paper is to investigate the causes of energy inefficiencies prevalent in these homes so that appropriate retrofit choices can be offered to homeowners. Design/methodology/approach This research presents a case study of a vacation rental home whose energy consumption was investigated in depth and energy inefficiencies identified through modeling using energy modeling software, eQUEST. Simulations were performed to identify viable retrofit scenarios. Findings While improvement in the building envelope such as providing shades/overhangs on the windows, reducing infiltration and increasing insulation of the exterior wall did not show promising results for savings on energy cost, other improvements such as use of highly efficient lamps, tank-less water heater system and occupancy sensors showed viable investment options with shorter payback periods. It was also found that energy use intensity of sampled houses was about half of the average of US residential buildings, which could primarily be attributed to the seasonal nature of occupancy of these houses. Originality/value There is a dearth of literature pertaining to energy efficiency-related retrofits of coastal vacation homes. This research fills that gap to some extent by addressing this issue with an ultimate aim of assisting homeowners in retrofit decision-making.

Ghg Savings

Purpose The purpose of this paper is to quantify the potential levels of greenhouse gas (GHG) and cost savings from a set of households’ energy saving measures, considered as “everyday choices”. Design/methodology/approach Four areas of living were selected for the study: household electricity, space heating, transport and food consumption. The study used a quantitative research approach in which the impact of selected scenarios of an average Finnish household was assessed. Findings Findings suggest that GHG savings from behavioural change regarding household electricity remain marginal in comparison to savings gained from transportation related measures. Transportation also provides the most cost-efficient ways to decrease GHGs but not in all cases. Based on the results, the authors suggest that smart technologies, such as on-line, active feedback systems could have a major role in guiding household energy use. Also, given the high GHG savings from transport, the authors highlight the importance of providing infrastructure and services for clean mobility, and in designing well-functioning and compact cities enabling shorter travels. Originality/value The aim of our study was twofold – by analysing the case household’s choices, we obtained information on environmental and economic impacts, but in addition to this, the aim was to open discussion on the role of households in tackling climate change and how to support households in making sustainable choices. Although research regarding household energy behaviour is vast, so far very few studies have focused on both economic and environmental impacts of households’ everyday actions.

Transport Domain

Road freight transport is believed by many to be the first transport domain in which driverless (DL) vehicles will have a significant impact. However, in current literature almost no attention has been given to how the diffusion of DL trucks might occur and how it might affect the transport system. To make predictions on the market uptake and to model impacts of DL truck deployment, valid cost estimates of DL truck operations are crucial. In this paper, an analysis of costs and cost structures for DL truck operations, including indicative numerical cost estimates, is presented. The total cost of ownership for DL trucks compared with that for manually driven (MD) trucks has been analyzed for four different truck types (16-, 24-, 40-, and 64-ton trucks), for three scenarios reflecting pessimistic, intermediate, and optimistic assumptions on economic impacts of driving automation based on current literature. The results indicate that DL trucks may enable substantial cost savings compared with the MD truck baseline. In the base (intermediate) scenario, costs per 1,000 ton-kilometer decrease by 45%, 37%, 33%, and 29% for 16-, 24-, 40-, and 60-ton trucks, respectively. The findings confirm the established view in the literature that freight transport is a highly attractive area for DL vehicles because of the potential economic benefits.

Purpose The purpose of this paper is to differentiate human responses to different light switch designs to determine the effects of these common interfaces on user perceptions and use of electric lighting in public buildings. Design/methodology/approach Empirical studies were conducted to assess and examine user perceptions with regard to design characteristics of light switches, and occupants’ use of electric lighting was examined through field observations made in a public toilet. Findings The results point to the possibility of identifying characteristics of light switches that attract user attention and thereby encourage energy-saving behaviour in public buildings. A light switch perceived as simple but oversized affected occupants to turn off the lights more frequently when leaving the space under study as compared to switches of normal size. Research limitations/implications Information on user perceptions of light switches may be limited by the assessments being carried out only in controlled environments. Assessing user perceptions in field observations is thus desirable, as it will provide more information on the perceptions in actual settings. Practical implications Effective design of user interfaces could provide a means of lowering energy use from electric lighting by affecting the behaviour of users. Using user perceptions to define critical design characteristics could contribute to design improvements in the interfaces with respect to users’ viewpoints. Originality/value This paper contributes to the subject with a basic, field-based approach to formulating an understanding of how design via user perceptions may encourage energy-saving behaviour.

Purpose – The purpose of this paper is to analyse the mutual learning implications for service productivity of the characteristics of service and service production. Design/methodology/approach – This is a conceptual paper. The starting point is, first of all, that productivity as a management concept should help a firm to manage its economic profit, and secondly, that service organizations are open systems, where the customers participate as co-producers and are exposed to the firm’s production resources and processes. Unlike in manufacturing, to understand productivity in service organizations as a means of managing profit, cost effects and revenue effects of changes in the productions system cannot be separated. Due to the interaction between customers and the firm’s resources during service production, dialogical collaboration between them develops. This enables mutual learning. Findings – Given the social dynamics in service production processes, four learning processes that influence service productivity are identified. Two processes enhance the organizations’s internal efficiency (cost savings), and two enhance its external effectiveness (perceived quality, revenue generation); two are organization-driven, two are customer-driven. Research limitations/implications – The mutual learning model demonstrates how the service provider by learning from the dynamics of service encounters in many ways can manage the productivity of the organizations’s processes. It shows that learning enables improvement of service productivity through effects enhancing both internal efficiency and external effectiveness. Originality/value – In a productivity context, learning has not earlier been studied as a mutual learning phenomenon.

Recent years have seen the approvals, more so in the EU than the United States, of follow-on biological drugs. These products have been new formulations of recombinant therapeutic proteins, developed to compete with the marketed originator products. Intended to closely mimic the originator products in terms of chemistry and therapeutic properties, these so-called ‘biosimilar’ products were initially conceived to be developed according to abbreviated development programmes, presumably at a substantial cost savings to both the drug developer and the consumer. With several such products now recently approved, however, it has become clear that their development programmes have been quite extensive and not particularly abbreviated. Accordingly, cost savings to consumers appear to be relatively modest.
