Managing the adverse thermal effects of urban development in a densely populated Chinese city.
Guangzhou city in South China has experienced an accelerated urban development since the 1980s. This paper examines the impact of the urban development on urban heat islands through a historical analysis of urban-rural air temperature differences. Remote sensing techniques were applied to derive information on land use/cover and land surface temperatures and to assess the thermal response patterns of land cover types. The results revealed an overriding importance of urban land cover expansion in the changes in heat island intensity and surface temperature patterns. Urban development was also related to a continual air temperature increase in the 1980s and 1990s. The combined use of satellite-derived vegetation and land cover distributions with land surface temperature maps provides a potential useful tool for many planning applications. The city's greening campaigns and landscaping designs should consider the different cooling effects of forest, shrubs and grassy lawns for temperature control and should plant more tall trees.

The role of the orthopedist in injury prevention.
Injury is an endemic disease process that is a leading cause of death and the leading cause of disability in the United States today. Among physicians, the orthopedic surgeon is most likely to be consulted by injured patients. Traditionally, orthopedists have played an important role in injury prevention as exemplified by the field of sports medicine. Three mechanisms have been demonstrated to be effective means of controlling the injury problem: (1) persuading persons at risk of injury to alter their behavior; (2) requiring individual behavior changes by law or administrative rule; and (3) providing automatic protection by product and environmental design. Specific strategies for implementing injury-prevention programs by the orthopedic surgeon are physician education, patient education, and public education.

Community impact of anticoagulation services: rationale and design of the Managing Anticoagulation Services Trial (MAST).
We describe the design of the Managing Anti-coagulation Services Trial (MAST), a practice-improvement trial testing whether anticoagulation services are a preferred method of managing anticoagulation for stroke prevention among patients with atrial fibrillation. Most randomized trials within the health care environment are designed as efficacy studies to determine what works under ideal conditions or ideal clinical practice. In contrast, effectiveness trials seek to generalize the results of efficacy studies by determining what works under more typical practice conditions. Practice-improvement trials are effectiveness trials that examine the management of a clinical problem in the context in which care is usually given. Noteworthy features of the MAST include defining the intervention in functional terms and collaboration with managed care organizations.

The relationship between convenience of destinations and walking levels in older women.
PURPOSE: To examine the relationship between physical activity and (1) convenience of destinations, measured by whether destinations (such as a park, trail, businesses, and services) are within walking distance of the home, and (2) participants' perception of the quality of their neighborhood surroundings for walking, captured with a global neighborhood "walkability" rating. DESIGN: Cross-sectional analysis of data obtained in 1999. SETTING: Community in southwest Pennsylvania. SUBJECTS: Older Caucasian women (n = 149, mean age = 74.2 years). Response rate = 79%. MEASURES: Walking levels, leisure-time physical activity, and features of the neighborhood environment were measured with interviewer-administered questionnaires. Physical activity was also measured objectively with a pedometer. RESULTS: Living within walking distance (defined as within a 20-minute walk of home) of a park; biking or walking trail; or department, discount, or hardware store was related to higher pedometer readings (p < .01). In addition, there was a positive trend between the sum of destinations within walking distance of home and activity levels measured by pedometer and questionnaire (p < .01). There was also a positive trend between participants' neighborhood "walkability" rating and activity levels measured by pedometer and questionnaire (p < .01). CONCLUSION: These findings suggest that the ability to make utilitarian walking trips from home and the perception of having favorable neighborhood surroundings for walking are associated with increased physical activity levels in older women.

Distribution of room size in hospitals.
In the design of such complex buildings as hospitals the planner's problem is to provide a minimal amount of permanent structure so that it shall not get in the way of functional behavior of the occupants and their ability to change their environment. The purpose of this study was to discover which intervals seem to occur in hospitals by measuring the room size distribution found in existing buildings or buildings ready for construction. The results seem to confirm that the range of room sizes required is small and that exceptions are relatively rare.

Recommendations for environmental design research correlating falls and the physical environment.
The risk of falls by aging individuals (55 years or older) is increased by physical elements within the built environment. Many environmental factors are considered high-risk hazards that can lead to serious injuries such as hip fractures. This article lists the design features most often mentioned in the literature as possible contributing factors to falls that result in injury. In addition, recommendations for research to assist designers, architects, planners, facilities management teams, and health care providers in designing physical environments that meet the specific requirements of individual users are offered. With concrete empirical research, the risk of falls and consequent injuries can be reduced, making the built environment safer and more user-friendly.

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.

Enhancing maximum measurable sound reduction index using sound intensity method and strong receiving room absorption.
The sound intensity method is usually recommended instead of the pressure method in the presence of strong flanking transmission. Especially when small and/or heavy specimens are tested, the flanking often causes problems in laboratories practicing only the pressure method. The purpose of this study was to determine experimentally the difference between the maximum sound reduction indices obtained by the intensity method, RI,max, and by the pressure method, Rmax. In addition, the influence of adding room absorption to the receiving room was studied. The experiments were carried out in an ordinary two-room test laboratory. The exact value of RI,max was estimated by applying a fitting equation to the measured data points. The fitting equation involved the dependence of the pressure-intensity indicator on measured acoustical parameters. In an empty receiving room, the difference between RI,max and Rmax was 4-15 dB, depending on frequency. When the average reverberation time was reduced from 3.5 to 0.6 s, the values of RI,max increased by 2-10 dB compared to the results in the empty room. Thus, it is possible to measure wall structures having 9-22 dB better sound reduction index using the intensity method than with the pressure method. This facilitates the measurements of small and/or heavy specimens in the presence of flanking. Moreover, when new laboratories are designed, the intensity method is an alternative to the pressure method which presupposes expensive isolation structures between the rooms.

Healthy naturally occurring retirement communities: a low-cost approach to facilitating healthy aging.
Naturally occurring retirement communities (NORCs) are broadly defined as communities where individuals either remain or move when they retire. Using the determinants of health model as a base, we hypothesize that some environmental determinants have a different impact on people at different ages. Health benefits to living within NORCs have been observed and likely vary depending upon where the specific NORC exists on the NORC to healthy-NORC spectrum. Some NORC environments are healthier than others for seniors, because the NORC environment has characteristics associated with better health for seniors. Health benefits within healthy NORCs are higher where physical and social environments facilitate greater activity and promote feelings of well-being. Compared to the provision of additional medical or social services, healthy NORCs are a low-cost community-level approach to facilitating healthy aging. Municipal governments should pursue policies that stimulate and support the development of healthy NORCs.

Reconstruction techniques for energy-absorbing guardrail end terminals.
Steel beam longitudinal barriers protect errant vehicles from roadside hazards; when impacted, they safely redirect the impacting vehicle and minimize the probability of serious injury. Guardrail end terminals are devices placed on the ends of longitudinal barriers and are frequently hit by vehicles that leave the roadway. Crash reconstruction is the effort to determine how a vehicle crash has occurred. Reconstruction is performed by several groups, including designers and testers of roadside safety devices so that they design and test for real-world conditions, and also by departments of transportation in order to determine appropriate warrants, maximizing the benefit-cost ratio for limited resources. This paper focuses on two items: first, the numerous types of energy-absorbing guardrail end terminals are identified and delineated and second, a crash reconstruction technique for determining the initial velocity of a vehicle impacting a guardrail end terminal based upon conservation of momentum and conservation of energy is developed. By understanding the types of guardrail terminals and being able to reconstruct real-world crashes, highway planners, designers and maintenance people will have significant more information than is currently available to aid in the goal of mitigating roadside crashes.

Sampling challenges posed by continental-scale soil landscape modeling.
Limited research exists to guide the development of continental-scale field sampling approaches. We developed a method to compare different sampling schemes designed for continental-scale environmental analysis. Using simulated annealing, we produced hypothetical soil property surfaces for the conterminous United States. The surfaces exhibited varying degrees of polygonality and conditioning by existing soil datasets. Differences in mean between a gridded sample and a polygon-centered sample were evaluated using randomization and other statistical tests. We saw a weak evidence in support of the hypothesis that if a polygonal structure exists in a surface being sampled, then it should be utilized during the actual sampling routine. We saw a somewhat stronger evidence for the hypothesis that differences in local sample density across a continental trend surface can lead to significant sampling bias. Ultimately, the success of different sampling strategies designed for use in continental-scale environmental analysis will largely depend on the ability to anticipate the spatial variability of the variable being measured.

The cigarette pack as image: new evidence from tobacco industry documents.
OBJECTIVES: To gain an understanding of the role of pack design in tobacco marketing. METHODS: A search of tobacco company document sites using a list of specified search terms was undertaken during November 2000 to July 2001. RESULTS: Documents show that, especially in the context of tighter restrictions on conventional avenues for tobacco marketing, tobacco companies view cigarette packaging as an integral component of marketing strategy and a vehicle for (a) creating significant in-store presence at the point of purchase, and (b) communicating brand image. Market testing results indicate that such imagery is so strong as to influence smoker's taste ratings of the same cigarettes when packaged differently. Documents also reveal the careful balancing act that companies have employed in using pack design and colour to communicate the impression of lower tar or milder cigarettes, while preserving perceived taste and "satisfaction". Systematic and extensive research is carried out by tobacco companies to ensure that cigarette packaging appeals to selected target groups, including young adults and women. CONCLUSIONS: Cigarette pack design is an important communication device for cigarette brands and acts as an advertising medium. Many smokers are misled by pack design into thinking that cigarettes may be "safer". There is a need to consider regulation of cigarette packaging.

Architecture of authorization mechanism for medical data sharing on the grid.
Data security is becoming increasingly important as the Grid matures. The advances of the Grid have allowed scientists and researchers to build a data grid where they can share and exchange research-related data and information. In reality, however, these specialists do not benefit enough from this data grid. The reason is that the current Grid does not have sufficiently robust and flexible data security. We investigate a medical data-sharing environment where medical doctors and scientists can securely share clinical and medical research data. We show medical data sharing that takes advantage of PERMIS, or an RBAC-based authorization system that achieves XML element level access control. We also describe the lessons learnt in designing the environment as well as a comparison with other existing authorization mechanisms.

Safer Choices: a multicomponent school-based HIV/STD and pregnancy prevention program for adolescents.
Given the serious consequences of HIV infection, other STDs, and pregnancy among teens, professionals must develop and evaluate new approaches to reduce risks associated with adolescent sexual behavior. The Safer Choices intervention is a comprehensive, theoretically based program designed to reduce risk behaviors and increase protective behaviors to prevent HIV, other STDs, and pregnancy among high school adolescents. The program includes five components: a School Health Promotion Council involving administrators, school staff, students, parents, and community members; curriculum and staff development activities; school environment activities designed and implemented by a team of peer educators; parent education activities; and school-community linkage activities. The School Health Promotion Council is responsible for planning and overseeing program implementation. This article describes the theoretical framework, process for intervention development, and key intervention strategies used in Safer Choices.

The influence of urban density and drainage infrastructure on the concentrations and loads of pollutants in small streams.
Effective water quality management of streams in urbanized basins requires identification of the elements of urbanization that contribute most to pollutant concentrations and loads. Drainage connection (the proportion of impervious area directly connected to streams by pipes or lined drains) is proposed as a variable explaining variance in the generally weak relationships between pollutant concentrations and imperviousness. Fifteen small streams draining independent subbasins east of Melbourne, Australia, were sampled for a suite of water quality variables. Geometric mean concentrations of all variables were calculated separately for baseflow and storm events, and these, together with estimates of runoff derived from a rainfall-runoff model, were used to estimate mean annual loads. Patterns of concentrations among the streams were assessed against patterns of imperviousness, drainage connection, unsealed (unpaved) road density, elevation, longitude (all of which were intercorrelated), septic tank density, and basin area. Baseflow and storm event concentrations of dissolved organic carbon (DOC), filterable reactive phosphorus (FRP), total phosphorus (TP) and ammonium, along with electrical conductivity (EC), all increased with imperviousness and its correlates. Hierarchical partitioning showed that DOC, EC, FRP, and storm event TP were independently correlated with drainage connection more strongly than could be explained by chance. Neither pH nor total suspended solids concentrations were strongly correlated with any basin variable. Oxidized and total nitrogen concentrations were most strongly explained by septic tank density. Loads of all variables were strongly correlated with imperviousness and connection. Priority should be given to low-impact urban design, which primarily involves reducing drainage connection, to minimize urbanization-related pollutant impacts on streams.
