Abstract

Although research shows that acceptance, trust, and risk perception are often related, little is known about the underlying patterns of causality among the three constructs. In the context of a waterborne disease outbreak, we explored via zero-order/partial correlation analysis whether acceptance predicts both trust and risk perception (associationist model), or whether trust influences risk perception and acceptance (causal chain model). The results supported the causal chain model suggesting a causal role for trust. A subsequent path analysis confirmed that the effect of trust on acceptance is fully mediated by risk perception. It also revealed that trust is positively predicted by prior institutional trust and communication with the public. Implications of the findings for response strategies to contamination events are discussed. © 2013 Wiley Periodicals, Inc.

66. The transformative effect of the introduction of water volumetric billing in a disadvantaged housing area in Sweden

Author

Mangold, M., Morrison, Gregory, Harder, R., Hagbert, P., Rauch, S., Mangold, M., Morrison, Gregory, Harder, R., Hagbert, P., and Rauch, S.

Abstract

© IWA Publishing 2014. Domestic water payment schemes are often a product of their time, place and what is perceived to be customary. Aspects that payment schemes can take into account include resource conservation, equity, maintainability, and profitability. In contemporary Sweden profitable environmentally sustainable solutions are promoted, such as the introduction of volumetric billing of water in rental apartments. This paper describes the detailed consequences of this change in the payment structure for domestic water in terms of reduced resource consumption, direct impact on household economies and perceptions of the system's change process. By combining high-resolution quantitative data on water usage and socio-economic household characteristics with qualitative data from semistandardized interviews with residents, it is possible to identify the different impacts of the system's change and how the process was experienced. It was shown that while water usage decreased by 30%, 63% of the households had increased monthly costs, and unemployed residents were further disadvantaged and closer to social exclusion. Focusing on making environmental sustainability profitable, as posited in ecological modernization theory, may shadow negative impacts on social sustainability.

67. Quantification of goods purchases and waste generation at the level of individual households

Author

Harder, R., Kalmykova, Y., Morrison, Gregory, Feng, F., Mangold, M., Dahlén, L., Harder, R., Kalmykova, Y., Morrison, Gregory, Feng, F., Mangold, M., and Dahlén, L.

Abstract

Quantifying differences in resource use and waste generation between individual households and exploring the reasons for the variations observed implies the need for disaggregated data on household activities and related physical flows. The collection of disaggregated data for water use, gas use, electricity use, and mobility has been reported in the literature and is normally achieved through sensors and computational algorithms. This study focuses on collecting disaggregated data for goods consumption and related waste generation at the level of individual households. To this end, two data collection approaches were devised and evaluated: (1) triangulating shopping receipt analysis and waste component analysis and (2) tracking goods consumption and waste generation using a smartphone. A case study on two households demonstrated that it is possible to collect quantitative data on goods consumption and related waste generation on a per unit basis for individual households. The study suggested that the type of data collected can be relevant in a number of different research contexts: eco-feedback; user-centered research; living-lab research; and life cycle impacts of household consumption. The approaches presented in this study are most applicable in the context of user-centered or living-lab research. For the other contexts, alternative data sources (e.g., retailers and producers) may be better suited to data collection on larger samples, though at a lesser level of detail, compared with the two data collection approaches devised and evaluated in this study. © 2014 by Yale University.

Abstract

In this work, we report the characterization of a quantum cascade laser frequency comb with an optical power of 1.05W at λ~8.2 μm. A 4.5mm long device has a high reflectivity coating on the back facet as well as a top cladding designed to lower the group velocity dispersion and is operated at 258 K. Very strong (more than 60 dB) narrow beatnotes are shown, and frequency comb operation is obtained on a bandwidth of 85 cm-1 in a very large range of light-versus current characteristics. A bandwidth of 82 cm-1 has a power per mode of more than 1 mW and an average power per mode of 4.1 mW. Finally, a multi-heterodyne spectrum with 215 lines covering an optical bandwidth of more than 70 cm-1 measured with lasers showing similar performances is presented with very good line separation.

90. Conceptualizing the water sensitive home in Sweden

Author

Mangold, M., Morrison, Gregory, Mangold, M., and Morrison, Gregory

Abstract

We define the water sensitive home by assigning attributes to relevant aspects of water in the home. The intention of this study is to look at more physical attributes and leaving the social dimensions to later, more applied studies. Fig. 1 below illustrates the attributes. Table 1 gives the unit and indicator used for assessing each attribute. We build upon the work done by Hellström et al. (2004), Lundin and Morrison (2002) when we define attributes. The attributes are grouped depending on their mathematical nature, environmental loads are negative per definition, risks cannot be completely avoided, resource consumption should be limited but is needed and thus have an optimal level, likewise is accessibility regulated by authorities. In different contexts the optimal levels are different, the "sides" of the green building in fig. 1, depending on regulations. Furthermore a minimal, or human right, level has been identified based on WHO (2011).
