This research adds an action research approach to mixed methods to understand the drivers and barriers to residential waste minimisation in Palmerston North, New Zealand. While local, national, and global structural barriers persisted outside the participants’ immediate control, action research enhanced waste minimisation practices within the limits of these structural barriers. The reflexive and collaborative principles of action research allowed research participants to identify individualised needs and challenges. Thus, the research proceeded according to the participants’ circumstances. Some of the key drivers included a sense of accountability, active learning, social support, convenience, affordability, and access to information and resources. The participants also offered recommendations to the City Council, producers, and policy-makers to enhance residential waste minimisation in Palmerston North. While the value-action gap persists in purely quantitative waste research seeking to understand and change waste behaviour, action research was beneficial as it added a more nuanced understanding of participants’ waste behaviours. It also contextualised waste-related practices and attitudes in a specific locale. 相似文献

US residential and commercial buildings were responsible for about 41 exajoules (EJ) of primary energy use per year in 2002,
accounting for approximately 9% of the world fossil-fuel related anthropogenic carbon (C) emissions of 6.7 Gt that contribute
to climate change. US Government-sponsored building energy efficiency research and implementation programs are focused on
reducing energy consumption in US residential and commercial buildings and reducing these carbon (C) emissions. Although not
specifically intended for adaptation to a warmer climate and less effective than under today’s cooler climate, these programs
also could help reduce energy demand in a future warmer world. Warming scenarios projected by the United Nations Intergovernmental
Panel on Climate Change (IPCC) in 2001 imply net overall decreases in both site energy and primary energy consumption in US
residential and commercial buildings, largely because of the reduced need for heating. However, there would be as much as
a 25% increase in building space cooling demand and a significant part of the increase could be offset by energy-efficiency
improvements in buildings. Overall, in the US, buildings-related energy efficiency programs would reduce site energy consumption
in buildings in the US by more than 2 EJ in 2020 and primary energy by more than 3.5 EJ, more than enough to offset the projected
growth in cooling energy consumption due to climate change and growth in the US building stock. The savings would have an
estimated annual net value at 2005 energy prices of between $45.0 and $47.3 billion to consumers.

ABSTRACTResidential care has increased in number of facilities and has grown in density in urban areas, yet it is disproportionately dispersed in cities and only beginning to meet the current long-term care need of older adults as an alternative to institutional and in-home care. California State Department of Social Services residential care facility data were linked with Los Angeles County census tract data to examine the spatial distribution of facilities through hot spot analysis of clusters of small and large facilities and zero-inflated negative binomial regression of census tract facility counts on older age and race groups, older disabled adults, and older adults in poverty in the area. The results show clusters of large facilities west of downtown Los Angeles and clusters of small facilities in the northern suburbs of the city in the San Fernando Valley. Increases in pre- and early-retired adults and older Hispanics in census tracts are associated with the greatest decreases in facility tract capacity in the area, whereas increases in the oldest old and older disabled adults are associated with the greatest increases. Understanding spatial disparities in residential care can help local agencies and developers plan and partner in more intentional and equitable development of facilities. The greatest opportunity for such development may lie in institutional tools for eldercare facility development such as the eldercare facility ordinance of Los Angeles and development of board and care facilities in residential zones of Los Angeles and other cities. 相似文献

Defining agents' behaviors to simulate complex residential development using multicriteria evaluation 总被引:4,自引:0,他引:4
Cellular automata (CA) have been increasingly used to simulate complex geographical phenomena. These models may have limitations on reflecting individuals' behaviors which should be considered in urban simulation. Agent-based modeling can solve some of the problems in addressing individuals' influences in urban systems. However, there is a general lack of methodology on how to define agents' properties. This paper uses multicriteria evaluation techniques to determine some of the parameters for the agent-based model. Empirical data from GIS are used to define agent's properties. Sensitivity analysis is also carried out to assess the influences of parameters on simulation outcomes. This model has been applied to the simulation of the residential development in a fast growing city, Guangzhou, in south China. 相似文献

Water quality deterioration often occurs in secondary water supply systems (SWSSs), and increased heavy metal concentrations can be a serious problem. In this survey, twelve residential neighborhoods were selected to investigate the influence of SWSSs on the seasonal changes in heavy metal concentrations from input water to tank and tap water. The concentrations of nine evaluated heavy metals in all groups of water samples were found to be far below the specified standard levels in China. The concentrations of Fe, Mn, and Zn increased significantly from the input water samples to the tank and tap water samples in spring and summer (p < 0.05), especially for the water samples that had been stagnant for a long time. Negative correlations were found between most of the heavy metals and residual chlorine (Fe, Cu, Zn, and As, r = -0.186 to -0.519, p < 0.05). In particular, a high negative correlation was observed between Fe and residual chlorine (r = -0.489 to -0.519, p < 0.01) in spring and summer. Fe and Mn displayed positive correlations with turbidity (r = 0.672 and 0.328, respectively; p < 0.05). In addition, Cr and As were found to be positively associated with some nutrients (NO3−, TN, and SO42−; r = 0.420-0.786, p < 0.01). The material of the storage tanks had little influence on the difference in heavy metal concentrations. Overall, this survey illustrated that SWSSs may pose a chronic threat to water quality and could provide useful information for practitioners. 相似文献

Some of the greatest challenges for managing residential development occur at the interface between the terrestrial and aquatic ecosystems--in a lake's riparian area. Land use planners need a framework they can use to identify development hotspots, areas were the next push for development will most likely occur. Lake riparian development profiles provide a framework for linking ecological and social factors important to development. In a test of this framework in northern Minnesota, researchers identified seven constructs influencing riparian area development: current general development, current housing development, and availability, accessibility, suitability, aesthetics, and proximity to services. Profiles display a lake's value for each construct relative to the range of values for all lakes in the county. Maps, developed using indicators for several constructs, allow us to identify how the factors interact and are dispersed across the landscape. These profiles help policy makers, planners, and managers identify lakes that are potential development hotspots so they can take timely steps to manage development or control the impacts of development. 相似文献
