The Image of Chemistry Presented by the Science Museum, London in the Twentieth Century: An International Perspective
Peter Morris
Hyle : International Journal for Philosophy of Chemistry , 2006,
Abstract: How has chemistry been presented at the Science Museum, London, during the 20th century? After an overview of the history of the Science Museum and its chemistry galleries, four galleries are considered in depth (1906, 1926, 1977, and 1999). The importance of the curators' external constituency of chemists and chemical educators is emphasized. The image of chemistry at the Science Museum has concentrated on the general utility of chemistry and chemistry as a skilful craft. The presentation has been low-key rather than boosterist. A comparison is made with the chemistry galleries at the Deutsches Museum. Chemistry in the Deutsches Museum has put more emphasis on hands-on exhibits and the chemical industry. Science and technology museums have promoted chemistry in a quiet but successful way for many years, but their influence may have waned along with chemistry kits.
The Effectiveness of Energy Feedback for Conservation and Peak Demand: A Literature Review  [PDF]
Desley Vine, Laurie Buys, Peter Morris
Open Journal of Energy Efficiency (OJEE) , 2013, DOI: 10.4236/ojee.2013.21002
Abstract: This paper reviews electricity consumption feedback literature to explore the potential of electricity feedback to affect residential consumers’ electricity usage patterns. The review highlights a substantial amount of literature covering the debate over the effectiveness of different feedback criteria to residential customer acceptance and overall conservation and peak demand reduction. Researchers studying the effects of feedback on everyday energy use have observed substantial variation in effect size, both within and between studies. Although researchers still continue to question the types of feedback that are most effective in encouraging conservation and peak load reduction, some trends have emerged. These include that feedback be received as quickly as possible to the time of consumption; be related to a standard; be clear and meaningful and where possible both direct and indirect feedback be customised to the customer. In general, the literature finds that feedback can reduce electricity consumption in homes by 5 to 20 percent, but that significant gaps remain in our knowledge of the effectiveness and cost benefit of feedback.
Successful transition to retirement in Australia
Peter Forster,Mary Morris
Social Sciences Directory , 2012, DOI: http://dx.doi.org/10.7563/ssd_01_01_01
Abstract: This study proposed and investigated a model of retirement in which successful retirement in Australia is achieved by sustaining community connections. A total of 650 participants (360 men, Mage=61.08, 290 women, Mage=58.39) from the general community, over the age of 45, participated in the study. The participants completed online questionnaires including the Sense of Community Index (SCI-2), the DASS-21, and Satisfaction with Life Scale (SWLS). Consistent with the proposed model, this study found that sense of community for retirees was positively related to life satisfaction and negatively related to anxiety. Retirees who were members of community groups were happier than those who were employed, independent of the employed person’s community membership. For retirees, having a sense of community remained a significant predictor of happiness, even after controlling for self-rated health. The results suggest that community connections are important for a successful and healthy retirement, and therefore that retirement planning should include advice about creating positive connections with family, friends, and community.
A Study of the Stability Properties of SPH
Joseph Peter Morris
Physics , 1995,
Abstract: When using a formulation of Smooth Particle Hydrodynamics (SPH) which conserves momentum exactly the motion of the particles is observed to be unstable to negative stress. It is also found that under normal circumstances a lattice of SPH particles is potentially unstable to transverse waves. This document is a summary of a detailed report (Morris 1994) investigating the nature of these and other instabilities in depth. Approaches which may be used to eliminate these instabilities are suggested. It is found that the stability properties of SPH in general improve as higher order spline interpolants, approximating a Gaussian, are used as kernels.
Relativistic corrections to the Sellmeier equation allow derivation of Demjanov's formula
Peter C. Morris
Physics , 2010,
Abstract: A recent paper by V.V. Demjanov in Physics Letters A reported a formula that relates the magnitude of Michelson interferometer fringe shifts to refractive index and absolute velocity. We show here that relativistic corrections to the Sellmeier equation allow an alternative derivation of the formula.
Application of a Bayesian Network Complex System Model Examining the Importance of Customer-Industry Engagement to Peak Electricity Demand Reduction  [PDF]
Desley Vine, Laurie Buys, Jim Lewis, Peter Morris
Open Journal of Energy Efficiency (OJEE) , 2016, DOI: 10.4236/ojee.2016.52004
Abstract: This paper explores the importance of customer-industry engagement (CIE) to peak energy demand by means of a newly developed Bayesian Network (BN) complex systems model entitled the Residential Electricity Peak Demand Model (REPDM). The REPDM is based on a multi-disciplinary perspective designed to solve the complex problem of residential peak energy demand. The model provides a way to conceptualise and understand the factors that shift and reduce consumer demand in peak times. To gain insight into the importance of customer-industry engagement in affecting residential peak demand, this research investigates intervention impacts and major influences through testing five scenarios using different levels of customer-industry engagement activities. Scenario testing of the model outlines the dependencies between the customer-industry engagement interventions and the probabilities that are estimated to govern the dependencies that influence peak demand. The output from the model shows that there can be a strong interaction between the level of CIE activities and interventions. The influence of CIE activity can increase public and householder support for peak reduction and the model shows how the economic, technical and social interventions can achieve greater peak demand reductions when well-designed with appropriate levels of CIE activities.

Amenable groups with a locally invariant order are locally indicable
Peter Linnell,Dave Witte Morris
Mathematics , 2012,
Abstract: We show that every amenable group with a locally invariant partial order has a left-invariant total order (and is therefore locally indicable). We also show that if a group G admits a left-invariant total order, and H is a locally nilpotent subgroup of G, then a left-invariant total order on G can be chosen so that its restriction to H is both left-invariant and right-invariant. Both results follow from recurrence properties of the action of G on its binary relations.
The Equity-effectiveness Loop as a Tool for Evaluating Population Health Interventions
Welch,Vivian; Tugwell,Peter; Morris,Erin B.;
Revista de Salud Pública , 2008, DOI: 10.1590/S0124-00642008000600008
Abstract: population health is concerned with reducing health inequities, defined as being unfair and avoidable differences in health. the equity-effectiveness framework is described and illustrated; this is an evidence-based approach to assessing the effects of programmes and policies on health equity. such framework also assesses barriers and facilitators for improving health equity using four factors: access, diagnostic accuracy, adherence and compliance. this framework emphasises the importance of transferring knowledge for designing and implementing clinical and public health interventions to improve health in all socioeconomic strata, based on the best available evidence. the world health organisation collaborating centre on health technology assessment is now using this framework for organising the components of its equity-orientated, evidence-based toolkit.
Moving from Outsider to Insider: Peer Status and Partnerships between Electricity Utilities and Residential Consumers
Peter Morris, Laurie Buys, Desley Vine
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0101189
Abstract: An electricity demand reduction project based on comprehensive residential consumer engagement was established within an Australian community in 2008. By 2011, both the peak demand and grid supplied electricity consumption had decreased to below pre-intervention levels. This case study research explored the relationship developed between the utility, community and individual consumer from the residential customer perspective through qualitative research of 22 residential households. It is proposed that an energy utility can be highly successful at peak demand reduction by becoming a community member and a peer to residential consumers and developing the necessary trust, access, influence and partnership required to create the responsive environment to change. A peer-community approach could provide policymakers with a pathway for implementing pro-environmental behaviour for low carbon communities, as well as peak demand reduction, thereby addressing government emission targets while limiting the cost of living increases from infrastructure expenditure.
