Optimal allocation of water resources in Guangzhou City, South China.

Based on the theory of decompose-coordination for large-scale systems, a systematic optimal operation model with multi-objective programming is developed for optimal allocation of water resources in Guangzhou City, South China. The methods of hierarchical analysis and step by step toleration obligation are used in the process of coordination through the sub-systems. Through the integrated regulation of 13 reservoirs and 6 main rivers and the regional watersheds, estimated water amount for dry year (P=97%) is distributed optimally to 14 water resource units to meet water demand in the year 2020. Water shortage due to lack of runoff and insufficient water supply projects is analyzed. The scheme of water allocation within seven water resource districts is put forward to match the sustainable balance of water supply to water demand in Guangzhou City.

Cognitive mapping and elderly adults: verbal and location memory for urban landmarks.

This study provides a real-world memory task that extends the ecological validity of previous research on aging and spatial memory. Elderly individuals were found to have less accurate verbal recall of urban landmarks and location memory for landmarks than younger adults. In addition to these quantitative differences in environmental cognition, qualitative aspects of the data were explored. In order to explain the poorer memory performance of elderly adults, participants' use of a geographically based, organizational mnemonic was examined. Furthermore, discriminant analysis revealed that the elderly relied more than younger adults on certain building attributes for memory of urban landmarks. These building attributes include: high public use, high symbolic significance, naturalness of surroundings, direct access to streets, and unique architectural style.

Retirement communities and their life stages.

A developmental theoretical orientation is used to study age-dense environments for mature adults--retirement communities. By focusing on the community itself, we discovered two basic patterns of life-stage models that describe and explain the formation, development, and maturity stages of communities. Thirty-six communities in four states were visited by the researchers, who interviewed a variety of key insider and outsider informants. Retirement communities are both social and economic units. The development and viability of the community are related to two models based on residential ownership (Type I) versus rental (Type II) of land upon which their dwellings are located. Residents in both types of communities express satisfaction. In Type I, some communities may experience problems in self-government and community formation. In Type II communities, there is sometimes a threat of sale of the community by the owner--an event that is unanticipated by the residents and has profound repercussions.

Health museums or theme parks: a new approach to intersectoral collaboration.

This paper is an outline of a proposed initiative on intersectoral collaboration in health promotion--collaboration between health, tourist, cultural and entertainment sectors to provide a powerful mass educational experience about the human mind and body. There has been a recent rise in interest in using the technology of museums, science centres, exploratories and theme parks for the promotion of health. This revival is shown to have a historical tradition in the health education museum started in this century in Europe 75 years ago at the Deutsches Hygiene Museum and then spreading to the USA. The proposed Body, Mind, City Museum planned for Liverpool acts as a future model for a new type of health Museum; a mixture of science exploratorium and a Walt Disney-style them park. It is intended that "hand-on" exhibits using interactive video, computers, games and experiences will be used to test people's own capacities or to describe biological functions or processes. This will be combined with park rides and simulations with their inherent appeal of fun, movement and surprise, for example the ride through the blood vessels and the "walk-through brain". This type of venture has a number of special features and advantages; it is truly intersectoral, it may be self-financing, and it can provide a mass audience with a powerful individual experience.

Sowing the seeds for sustainable change: a community-based participatory research partnership for health promotion in Indiana, USA and its aftermath.

Community-based participatory research (CBPR) increasingly is being used in both developed and developing countries to study and address community-identified issues through a collaborative and empowering action-oriented process. In 2003-2005, a study was undertaken to document the impacts of CBPR on healthy public policy in the US. From an initial review of 80 partnership efforts, 10 were selected as best capturing the range and diversity of projects meeting the study criteria, and were the subject of in-depth case study analysis. This article presents and analyzes one of these cases, a collaboration between researchers at the Indiana University School of Nursing and the Healthy Cities Committee of New Castle, IN, USA. With its action component still underway a decade after the formal study's completion, the partnership was selected to enable an examination of sustainable change through CBPR. Beginning with a participatory door-to-door health survey of 1000 households using a non-probability quota sampling strategy, the project involved community members in many stages of the research process. A smoking rate of twice the national average was among the study findings that helped to galvanize the community into action. A variety of health promoting environmental and 'small p policy' changes were undertaken ranging from a bill restricting indoor smoking in public places to an initiative to develop a system of trails throughout the county to promote physical fitness and decreased reliance on automobiles. This article examines the evolution of the original CBPR partnership, its research methods and findings, and the environmental changes it sought to promote healthier lifestyles. Success factors, barriers and sustainability benchmarks are discussed. The case study offers an example of the potential of CBPR for helping to lay the groundwork for long-term sustainable change in support of healthier communities.

Root shock: the consequences of African American dispossession.

Urban renewal was one of several processes that contributed to deurbanization of American cities in the second half of the 20th century. Urban renewal was an important federal policy that affected thousands of communities in hundreds of cities. Urban renewal was to achieve "clearance" of "blight" and "slum" areas so that they could be rebuilt for new uses other than housing the poor. Urban renewal programs fell disproportionately on African American communities, leading to the slogan "Urban renewal is Negro removal." The short-term consequences were dire, including loss of money, loss of social organization, and psychological trauma. The long-term consequences flow from the social paralysis of dispossession, most important, a collapse of political action. This has important implications for the well-being of African Americans. It also raises important questions about the strength and quality of American democracy.

Traffic injury data, policy, and public health: lessons from Boston Chinatown.

We note that long-standing land use and transportation policy are critical factors in creating traffic conditions and will have to play a role in reducing injuries. We present the historical progression of events that created current traffic conditions in Boston Chinatown and an analysis of traffic-related injuries at the community level for the years 1996-1998. Injuries were found to be as likely on weekends as on weekdays and frequently occurred late at night. Nighttime occupant injuries were found to be more likely on Friday, Saturday, and Sunday nights (relative risk = 2.26; confidence interval = 1.35-3.78, P =.0014). Injuries varied significantly by location for occupant (P = <.001) and for pedestrian injuries (P =.039). There were no peaks of injuries at traditionally defined commuter hours, which have been the standard time for assessing "worst case" traffic impacts by developers and government agencies. There was, however, a strong association between injuries and vehicle volume at 9 intersections with simple configurations for AM and PM commuter hours (R(2) = 0.589, P =.010), resulting in a calculated increase of 3-5 injuries per year for each increase of 1,000 vehicles. There was no such association at 10 intersections with complex configurations (R(2) = 0.104, P =.397). The 24-hour weekend patterns of vehicle volumes showed that traffic abated only between 3 and 7 AM, and the patterns appeared qualitatively to mirror the 24-hour pattern of injuries, suggesting that they were also indicative of injury risk. We suggest that there is a need for both long-term changes in policy and more immediate interventions. We also conclude that researchers should be cautious about assuming that traffic patterns conform to naive expectations such as rush hour peaks.

Urbanization, urbanicity, and health.

A majority of the world's population will live in urban areas by 2007. The most rapidly urbanizing cities are in less-wealthy nations, and the pace of growth varies among regions. There are few data linking features of cities to the health of populations. We suggest a framework to guide inquiry into features of the urban environment that affect health and well-being. We consider two key dimensions: urbanization and urbanicity. Urbanization refers to change in size, density, and heterogeneity of cities. Urbanicity refers to the impact of living in urban areas at a given time. A review of the published literature suggests that most of the important factors that affect health can be considered within three broad themes: the social environment, the physical environment, and access to health and social services. The development of urban health as a discipline will need to draw on the strengths of diverse academic areas of study (e.g., ecology, epidemiology, sociology). Cross-national research may provide insights about the key features of cities and how urbanization influences population health.

A population health framework for inner-city mental health.

Dealing with mental health problems in the inner city presents a major challenge to planners and service providers. Traditional mental health service-oriented interventions often prove ineffective due to the complexity of individuals' needs. This article argues that a population health framework can be used to identify critical risk and protective factors and facilitate more effective, upstream, population-based interventions for mental health problems in the inner city. A community report card is seen as a useful measure of key indicators at any point in time and of changes over time at the community or neighborhood level. A number of issues with regard to report card development are identified and discussed, as is the process of creating a report card, including key domains and the organization of findings.

Where does walkability matter the most? An environmental justice interpretation of New Jersey data.

Physical inactivity contributes to a growing proportion of premature mortality and morbidity in the United States, and the last decade has been the focus of calls for action. Analysis of 340 residents of New Jersey found that 15%-20% reported multiple problems with using their immediate neighborhoods for physical activity. These respondents were disproportionately African Americans living in neighborhoods that they regard as only of fair or poor quality. Neighborhood walkability is a second-wave environmental justice issue meriting carefully designed research and ameliorative actions in concert with other neighborhood-level redevelopment activities.
