A novel spatiotemporal home heating controller design: system emulation and field testing

We have developed a spatiotemporal heating control algorithm for use in homes. This system utilises a combination of relatively low-tech hardware interfaced with electric heating systems and a smartphone interface to this hardware, and a central server that progressively learns users’ room-specific presence profiles and thermal preferences. This paper describes the associated spatiotemporal heating control algorithm, its evaluation utilising the dynamic building performance simulation software EnergyPlus, and a longitudinal deployment of the algorithm controlling a quasi-autonomous spatiotemporal home heating system in three domestic homes. In this we focus on the prediction of occupants’ presence and preferred set-point temperature as well as on the calculation of optimum start time and the utilisation of user-scheduled absences; this for two comfort strategies: to maximise comfort and to minimise discomfort. The former aims to deliver conditions equating to a ‘neutral’ thermal sensation, whereas the latter targets a ‘slightly cool’ sensation with corresponding heating energy savings. Simulation results confirmed that the algorithm functions as intended and that it is capable of reducing energy demand by a factor of seven compared with EnergyStar recommended settings for programmable thermostats. Field study results align with these findings and highlight the possibility to reduce energy under the minimise discomfort strategy without compromising on occupants’ thermal comfort

Integrating human and ecosystem health through ecosystem services frameworks

The pace and scale of environmental change is undermining the conditions for human health. Yet the environment and human health remain poorly integrated within research, policy and practice. The ecosystem services (ES) approach provides a way of promoting integration via the frameworks used to represent relationships between environment and society in simple visual forms. To assess this potential, we undertook a scoping review of ES frameworks and assessed how each represented seven key dimensions, including ecosystem and human health. Of the 84 ES frameworks identified, the majority did not include human health (62%) or include feedback mechanisms between ecosystems and human health (75%). While ecosystem drivers of human health are included in some ES frameworks, more comprehensive frameworks are required to drive forward research and policy on environmental change and human health

Impacts of birds of prey on gamebirds in the UK: a review

The influence of predators on the distribution, density and dynamics of their prey species has long been of interest to ecologists and wildlife managers. Where the prey population is also utilised by humans, conflicts may arise through competition for a limited resource. Because gamebird shooting in the UK provides employment, recreation and income, the impact of birds of prey on gamebird populations has been the subject of intense debate for many years. A variety of approaches has been used to assess the impacts that raptors have on gamebird populations. Here we review the applicability and limitations of the methods used and assess the scientific evidence for population-level and economic impacts of raptors on gamebird populations in the UK. Raptors may, in some situations, take large numbers of gamebirds and may be an important proximate cause of mortality, although few studies have assressed the impacts of raptors on either breeding or pre-shooting densities. Two exceptions are studies of Hen Harrier and Peregrine predation on Red Grouse on moorland in Scotland and Sparrowhawk predation on Grey Partridge on farmland in England. Both these studies suggested that raptors could have population-level impacts when their gamebird prey was already at low density. Studies on predation of captively bred gamebirds suggest that numbers taken by raptors at release pens vary considerably and in a few cases raptors have been documented killing relatively large numbers. On the whole, however, it appears that raptors account for a relatively small proportion of mortality among released birds and the impact on subsequent shooting bags is unknown. We summarise important gaps in current knowledge and recommend specific areas for future research

A model for partner selection criteria in Energy from Waste projects

Energy from Waste is being deployed in both developed and developing economies as a route to reduce dependency on fossil fuels whilst making positive use of resources which might otherwise be landfilled. Energy from Waste supply chains are complex, with a rich diversity of partners and stakeholders involved. For this purpose, the selection of appropriate criteria to guide supply chain design, and in particular the selection of suppliers, is critical for success. In this study, a three-stage process was conducted to identify, refine and validate an evidence-based model. The evidence based model proposed comprises seven categories of criteria used in the design of these supply chains, namely Economic, Environmental, Location, Operations management, which has a sub-category of Plant operation, Political/Legal and Social. The work reported here supports practitioners and researchers involved in supply chain partner selection to systematise their thinking in relation to the criteria that may impact their study or project

Performance reporting by Malaysian local authorities : identifying stakeholder needs

The concept of public accountability promotes the need for a comprehensive set of performance-related information to satisfy the information needs of a diverse stakeholder interest group. However, literature concerned with the scope of information to be disclosed, and in particular within the context of a developing country, is limited. This paper identifies the information set which stakeholders of Malaysian local authorities consider relevant in the monitoring and assessment of local authority performance. Stakeholders indicated strong interest in performance information that is not traditionally disclosed in the financial statements: non-financial information particularly performance measurement of outputs, outcomes, efficiency and effectiveness. Disclosures in the Statement of Revenue and Expenditure and forward-looking information are generally regarded as the most important disclosures. The results of the study also indicate differences amongst stakeholders as to the level of importance that they place on certain items especially items related to internal policies and governance and financial position of the local authorities. The findings will be of significance to policy makers interested in improving the performance reporting of Malaysian public sector entities, particularly local authorities

Right needle, right patient, right time? A national flash-mob audit of thromboprophylaxis in palliative care

BACKGROUND: The prevention of hospital associated thrombosis in palliative care remains controversial yet many countries recommend the documented risk assessment and where appropriate pharmacological prophylaxis of inpatients with advanced cancer. AIM: To audit adherence to national guidelines which require hospitalised patients to be risk assessed and receive appropriate thromboprophylaxis. DESIGN: A one day "flash-mob" audit across multiple clinical inpatient sites across the United Kingdom. SETTING/PARTICIPANTS: Inpatients receiving palliative care within hospitals, hospices and specialist palliative care units across the United Kingdom. RESULTS: Data were collected from 1125 patients (514 hospital and 611 hospice/specialist palliative care units). Appropriate thromboprophylaxis was observed in 90 % of hospital and 90 % hospice/specialist palliative care units. Documented risk assessment was only found in 79 % and 71 % of patient notes respectively. Pharmacological thromboprophylaxis was contraindicated in 88 % of hospice/specialist palliative care unit patients due to bleeding risk or receiving end-of-life care. Twenty-four percent of patients in hospital had contraindications due to receiving end of life care, bleeding risk and thrombocytopenia. Patients in hospice/specialist palliative care units were of poorer performance status prior to admission with a history of gradual deterioration. Hospitalised patients were more likely to have been admitted following an acute deterioration of previous good performance status. CONCLUSION: Thromboprophylaxis guidelines were followed correctly for the majority of patients. There were considerable differences in the demographics of patients according to place of admission. Patients admitted to hospice/specialist palliative care units were sicker and had more contraindications to prophylaxis than those admitted to hospital. Thromboprophylaxis focused research data conducted in hospices is unlikely to be applicable to the care of palliative care patients admitted acutely to hospital
