The implications of cultural differences in laundry behaviours for design for sustainable behaviour: A case study between the UK,India and Brazil

Traditional research into sustainable design has typically focused on reducing the environmental impact of products during the manufacture and disposal stages of a products' lifecycle. The last decade, however, has seen an explosion of research into understanding and moderating user behaviour during the use phase of a products' lifecycle; often the most resource-intensive phase. One of the biggest factors that affects behaviour is a users cultural context; however, the effect of cultural context on design for sustainable behaviour has had little exploration in this relatively new research field.     

The considerations and limitations of feedback as a strategy for behaviour change

Design for Sustainable Behaviour (DfSB) is a maturing research area concerned with the application of design strategies to influence consumer behaviour during a products use phase towards more sustainable action. However, current DfSB research has focussed on strategy selection with little research into understanding the real-world impact of the behaviour changing interventions debated. This article presents the results of an extensive literature review of one specific DfSB strategy, feedback – a user agentive performance indicator. These findings exemplify the considerations and limitations of this particular approach to behaviour change, drawing on empirical research conducted by a breadth of authors, including two of the only medium-term case studies in the field of DfSB. Considerations discussed include the frequency, duration and accuracy of feedback; the selection of metrics and the presentation medium and mode; the use of ambience and the location of the installation. Limitations of feedback include the need for additional information and comparisons; the issue with multiple users; technical issues; relegation to background technology and the potential rebound effects. This article provides insights to both improve the effectiveness of future feedback design efforts and also to help facilitate discussion on feedbacks position as a strategy within DfSB.     

Making the user more efficient: design for sustainable behaviour

User behaviour is a significant determinant of a product's environmental impact; while engineering advances permit increased efficiency of product operation, the user's decisions and habits ultimately have a major effect on the energy or other resources used by the product. There is thus a need to change users' behaviour. A range of design techniques developed in diverse contexts suggest opportunities for engineers, designers and other stakeholders working in the field of sustainable innovation to affect users' behaviour at the point of interaction with the product or system, in effect ‘making the user more efficient’. Approaches to changing users' behaviour from a number of fields are reviewed and discussed, including: strategic design of affordances and behaviour‐shaping constraints to control or affect energy‐ or other resource‐using interactions; the use of different kinds of feedback and persuasive technology techniques to encourage or guide users to reduce their environmental impact; and context‐based systems which use feedback to adjust their behaviour to run at optimum efficiency and reduce the opportunity for user‐affected inefficiency. Example implementations in the sustainable engineering and ecodesign field are suggested and discussed.     

Accessibility and trust: the two dimensions of consumers’ perception on sustainable purchase intention

The aim of this article is to shed new light on which dimensions compose sustainable purchase intention (SPI) with the purpose of understanding what moves consumers to a potentially more sustainable behaviour. Even though several studies have researched which factors influence consumer’s intention to buy in a more sustainable way, no comparable research in consumer behaviour was found studying these dimensions in a triple bottom line perspective (profit, people, and planet) that could also provide future corporate and academic applications. Therefore, this article proposes a new construct – Consumers’ Perception on SPI, defined using the C-OAR-SE procedure and measured using exploratory and confirmatory factor analysis using two different samples. In-depth interviews and online survey to actual consumers of sustainable products were undertaken in partnership with a sustainable project using its database, guaranteeing that real consumers’ perceptions were gathered for this study. The construct is proposed with two dimensions (measured by nine items): Accessibility (including facets such as product lower pricing, availability in stores, and being sold within a convenient proximity to home) and Trust (including consumers needs such as: to get to know and trust products through understanding the labels; to have had good experiences in the past or simply to have new trial opportunities). Theoretical and practical implications of the findings are also discussed.     

Chaos and complexity in development

SUMMARY

The paper outlines some main features of chaos theory. Examples of chaotic systems in society and the environment are given. Spontaneous interaction of components, without being planned or directed, is known as ‘self-organising behaviour’. Chaos is an essential aspect of this self organisation, occurring in many forms. A chaotic system is defined as one that shows sensitivity to initial conditions. If the errors relative to the initial conditions become too great, the system will eventually collapse. Development projects are sensitive to such initial conditions. In particular, two examples in development are outlined in some detail and commented upon. One is the occurrence of a project promoting self-organising systems among the poorest of the poor. The other outlines how rehabilitation after resettlement in a power project has transgressed the ‘edge of chaos’ socio-emotionally, in spite of the socioeconomic development being good.     

Writing it down: suggestions for a new approach towards understanding pro-environmental behaviour

A fashionable field of enquiry – the relationship between expressed attitudes and actual behaviour in the context of sustainable development – is complex (Staats et al. 2004 Staats, H, Harland, P and Wilke, H. 2004. Effecting durable change: a team approach to improve environmental behaviour in the household. Environ Behav., 36(3): 341–367. [Crossref], [Web of Science ®] , [Google Scholar]) and difficult to apply in a policy-relevant manner (Aall and Norland 2005 Aall, C and Norland, I. 2005. The use of the ecological footprint in local politics and administration: results and implications from Norway. Local Environ., 10(2): 159–172. [Taylor & Francis Online] , [Google Scholar]). However, recent research indicates that the use of a household diary can be beneficial in helping to quantify household environmental impact, in educating householders about their impact, and in identifying major ‘behavioural turning points’, where householders may focus efforts to reduce their environmental impact (Hunter et al. 2006 Hunter, C, Carmichael, K and Pangbourne, K. 2006. Household ecological footprinting using a new diary-based data-gathering approach. Local Environ, 11(3): 307–327. [Taylor & Francis Online] , [Google Scholar]). In other words, the use of a diary by householders is a potentially powerful tool in encouraging and facilitating desired behavioural change. This paper reports on the initial findings of an innovative study that assessed the use of a household diary approach as a means of framing and collecting household environmental data and, critically, as an educational vehicle for bringing about behavioural change. Based on the initial findings, it is clear that there is some potential to develop practical policy measures that empower householders by allowing them to better grasp their environmental impact and, consequently, recoup positive implications in terms of financial savings (e.g. reducing the amount of food thrown out) and health benefits (e.g. more walking/cycling).     

Raising awareness of transport issues: The potential to bring about behavioural change?

Changes in the directions of transport policy in the UK in the last few years have led to a wider consideration of possible measures to bring about behavioural change, in particular measures which have the potential to reduce car dependence. Among the measures currently being implemented by local authorities are public awareness or travel awareness campaigns. This paper examines the findings of a research project which evaluated a travel awareness scheme in the context of an integrated transport policy. The research project monitored the attitudes, beliefs and intentions of a sample of the residents who had been targeted by the Maidstone Initiative for Sustainable Transport (MIST) implemented by Kent County Council and Maidstone Borough Council. The research project found some remarkably consistent attitudes about car and bus travel over a period of three years, It also found that whilst people seem to be aware of the impact of travel on the environment they do not consider the environmental impact with the same degree of importance as other attributes of travel. A further finding was a hidden desire to switch modes from the car. The paper will conclude by looking critically at the future for travel awareness campaigns.     

不同浓度的五氯酚对斑马鱼运动行为的影响

由于突发性水源污染频发,建立一种实时的风险监测评估系统十分迫切。本研究通过在线生物监测仪实时记录斑马鱼在五氯酚(PCP)中暴露前后的3D行为响应数据,分别从运动轨迹、游动速度(中值)、浮出水面频率及熵值4个指标分析斑马鱼的行为响应。结果表明：与对照组相比,暴露于低浓度(0.25、0.5 mg·L^-1)的PCP中的斑马鱼,其游动速度(中值)和熵值呈递减趋势,但趋势不明显,其浮出水面频率有不同程度的增加;而暴露于较高浓度(1.0、2.0 mg·L^-1)的PCP中的斑马鱼,其游动速度(中值)、浮出水面频率、熵值约有10 min的急速升高之后降低;暴露于高浓度(4.0 mg·L^-1)的PCP中的斑马鱼,所有指标均呈明显下降趋势。这表明斑马鱼的毒性行为响应随PCP的浓度变化而变化,所以可以通过监测鱼类的行为变化来反映水体的污染状况。因此,鱼类行为学研究在高浓度突发性水源污染的实时监测方面具有一定的应用前景。     

Incorporating behaviour into simple models of dispersal using the biological control agent Dicyphus hesperus

We explored the utility of incorporating easily measured, biologically realistic movement rules into simple models of dispersal. We depart from traditional random walk models by designing an individual-based simulation model where we decompose animal movement into three separate processes: emigration, between-patch movement, and immigration behaviour. These processes were quantified using experiments on the omnivorous insect Dicyphus hesperus moving through a tomato greenhouse. We compare the predictions of the individual-based model, along with a series of biased random walk models, against an independent experimental release of D. hesperus. We find that in this system, the short-term dispersal of these insects is described well by our individual-based model, but can also be described by a 2D grid-based biased random walk model when mortality is accounted for.     

Towards a complex model of disaster behaviour

This paper outlines why a move towards a complex adaptive systems model of behaviour is required if the goal is to generate better understanding of how individuals and groups interact with their environment in a disaster setting. To accomplish this objective, a bridge must be built between the broader social sciences and behavioural economics to incorporate discipline‐specific insights that are needed to move towards complexity. This is only possible through a deeper understanding of behaviour and how the environment in which they occur can influence actions. It is then that one can counteract the poor behavioural predictions, flawed policies based on myth, inefficient design, and suboptimal outcomes that have flourished in the absence of a complex adaptive systems model. This paper provides a conceptual framework that draws on concepts from across the natural and social sciences, such as behavioural economics, endocrinology, psychology, sociobiology, and sociology in order to build an interactive theory of disaster behaviour.
