Green multimedia: informing people of their carbon footprint through two simple sensors
In this work we discuss a new, but highly relevant, topic to the multimedia community; systems to inform individuals of their carbon footprint, which could ultimately effect change in community carbon footprint-related activities. The reduction of carbon emissions is now an important policy driver of many governments, and one of the major areas of focus is in reducing the energy demand from the consumers i.e. all of us individually.
In terms of CO2 generated from energy consumption, there are three predominant factors, namely electricity usage, thermal related costs, and transport usage. Standard home electricity and heating sensors can be used to measure the former two aspects, and in this paper we evaluate a novel technique to estimate an individual's transport-related carbon emissions through the use of a simple wearable accelerometer.
We investigate how providing this novel estimation of transport-related carbon emissions through an interactive web site and mobile phone app engages a set of users in becoming more aware of their carbon emissions. Our evaluations involve a group of 6 users collecting 25 million accelerometer readings and 12.5 million power readings vs. a control group of 16 users collecting 29.7 million power readings
Motivation crowding in real consumption decisions: Who is messing with my groceries?
We present evidence of crowding out of intrinsic motivation in real purchasing decisions from a field experiment in a large supermarket chain. We compare three instruments, a label, a subsidy and a neutral price change, in their ability to induce consumers to switch from dirty to clean products. Interestingly a subsidy framed as an intervention is less effective than either a label or a neutrally framed price change. We argue that this provides a new explanation for crowding behaviour: consumers are resistant to having the line of demarcation between public and private decision making moved - in either direction
Consumer's behaviour in assessing environmental impact of consumption - State of the art and challenges for modelling consumer's behaviour in life cycle-based indicators
The European Commission (EC) has been developing an assessment framework to monitor the evolution of environmental impact associated to the European Union (EU) consumption. The assessment framework should help to support a wide array of policies, such as those related to resource efficiency, eco-innovation and circular economy. The environmental impact of EU consumption is assessed adopting two sets of life cycle-based indicators: the Consumption footprint and the Consumer footprint, which have a complementary role in assessing those impacts.
The EU Consumer Footprint is the measurement of the environmental impacts based on the life cycle assessment (LCA) of products (or services) purchased and used in one year by an EU citizen. This is based on the results of LCAs of representative consumed products (and services, where relevant). Within the framework of this project, a dedicated area of research focused on the “Product use phase and consumption scenarios”, aiming at the examination of consumer behaviour types in view of further refinement of product use phase modelling and in support to the definition of scenarios on improved environmental behaviours. Whereas the production-based perspective helps in identifying domestic sectors, product groups and products responsible for emissions and resource use, the consumption-based perspective looks at the overall environmental impact induced by the domestic consumption. Each of the two perspectives on environmental impact has its use for policy-makers. This report is addressing variability in the use phase grounded on consumers' actual behaviour patterns, with reference to the aims presented before.
After a brief review of theories and models explaining consumer behaviours, this report discusses the main approaches for measuring the environmental impacts of consumption and the key drivers that influence consumers’ shift towards more envrionmentally friendly consumption choices and behaviours. Moreover, the possible link between behavioural sciences and Life Cycle Assessment, through the development of scenarios on consumer behaviour applied to the Basket of Products (BoPs) is discussed, together with the possibility to capture the rebound effects in these scenarios. Current knowledge gaps and related research needs are illustrated in the concluding section, highlighting possible future paths of research for the integration of behavioural economics into environmental assessment (e.g. to capture the rebound effects induced by household expenditure structure shifting, based on Engel’s curve), and to complement and further improve the approaches discussed herein.JRC.D.1-Bio-econom
Supporting community engagement through teaching, student projects and research
The Education Acts statutory obligations for ITPs are not supported by the Crown funding model. Part of the statutory role of an ITP is “... promotes community learning and by research, particularly applied and technological research ...” [The education act 1989]. In relation to this a 2017 TEC report highlighted impaired business models and an excessive administrative burden as restrictive and impeding success. Further restrictions are seen when considering ITPs attract < 3 % of the available TEC funding for research, and ~ 20 % available TEC funding for teaching, despite having overall student efts of ~ 26 % nationally.
An attempt to improve performance and engage through collaboration (community, industry, tertiary) at our institution is proving successful. The cross-disciplinary approach provides students high level experience and the technical stretch needed to be successful engineers, technologists and technicians.
This study presents one of the methods we use to collaborate externally through teaching, student projects and research
Wattsup? Motivating reductions in domestic energy consumption using social networks
This paper reports on the design, deployment and evaluation of “Wattsup”, an innovative application which displays live autonomously logged data from the Wattson energy monitor, allowing users to compare domestic energy consumption on Facebook. Discussions and sketches from a workshop with Facebook users were used to develop a final design implemented using the Facebook API. Wattson energy monitors and the Wattsup app were deployed and trialled in eight homes over an eighteen day period in two conditions. In the first condition participants could only access their personal energy data, whilst in the second they could access each others’ data to make comparisons. A significant reduction in energy was observed in the socially enabled condition. Comments on discussion boards and semi-structured interviews with the participants indicated that the element of competition helped motivate energy savings. The paper argues that socially-mediated banter and competition made for a more enjoyable user experience
Preserving the impossible: conservation of soft-sediment hominin footprint sites and strategies for three-dimensional digital data capture.
Human footprints provide some of the most publically emotive and tangible evidence of our ancestors. To the scientific community they provide evidence of stature, presence, behaviour and in the case of early hominins potential evidence with respect to the evolution of gait. While rare in the geological record the number of footprint sites has increased in recent years along with the analytical tools available for their study. Many of these sites are at risk from rapid erosion, including the Ileret footprints in northern Kenya which are second only in age to those at Laetoli (Tanzania). Unlithified, soft-sediment footprint sites such these pose a significant geoconservation challenge. In the first part of this paper conservation and preservation options are explored leading to the conclusion that to 'record and digitally rescue' provides the only viable approach. Key to such strategies is the increasing availability of three-dimensional data capture either via optical laser scanning and/or digital photogrammetry. Within the discipline there is a developing schism between those that favour one approach over the other and a requirement from geoconservationists and the scientific community for some form of objective appraisal of these alternatives is necessary. Consequently in the second part of this paper we evaluate these alternative approaches and the role they can play in a 'record and digitally rescue' conservation strategy. Using modern footprint data, digital models created via optical laser scanning are compared to those generated by state-of-the-art photogrammetry. Both methods give comparable although subtly different results. This data is evaluated alongside a review of field deployment issues to provide guidance to the community with respect to the factors which need to be considered in digital conservation of human/hominin footprints

Incorporating Human Beliefs and Behaviors into Wildlife Ecology
Like much of the global biosphere, wildlife species have experienced rapid declines during the Anthropocene. Wildlife ecologists have responded to these crises by developing a range of technologies, techniques, and large datasets, which together have revolutionized the field, provided novel insights into the movements and behaviors of animals, and identified new risks and impacts to wildlife in a human-dominated world. While these advances have been vitally important, wildlife ecology has been slower to recognize and incorporate humans themselves into its new research domains. The chapters of this dissertation explore methods for better incorporating human behaviors, beliefs, actions, and infrastructure into the theories and approaches in wildlife ecology that have flourished in the last two decades. The research presented here demonstrates the importance of linking human beliefs and behaviors to wildlife ecology both by presenting novel findings and by showing the opportunities missed when narrow approaches are applied to complex socio-ecological problems.In Chapter 1, I provide a general introduction on the theories underlying this research, contextualize the research questions in light of the loss and recovery of large predators, and describe the research site where I collected much of the data for this dissertation. In Chapter 2, I apply the methods of movement ecology to some of the first fine-scale telemetry data collected on rifle hunters. I draw conclusions about their individual, site-level, and regional-level hunting behaviors and discuss the broad implications of these findings for hunting management. In Chapter 3, I examine livestock-predator conflict using approaches from both ecology and the social sciences. I describe a form of selection bias that is likely widespread but unreported due to the omission of social data from ecological models of conflict, and I offer guidelines for combining and translating ecological and social research on conflict. In Chapter 4, I explore the ecological impacts of one of the most globally widespread human constructions, the fence. I show for the first time the potential extent of fencing at large scales and discuss the wide variety of ecological effects of fences for both humans and ecosystems. I further highlight biases and gaps in fence research that have thus far limited a complete understanding of the environmental effects of these features. In Chapter 5, I conclude by making recommendations regarding how research might better incorporate human perceptions, decisions, and actions into ecology
