Since motor vehicles are a major air pollution source, urban designs that decrease private automobile use could improve air quality and decrease air pollution health risks. Yet, the relationships among urban form, air quality, and health are complex and not fully understood. To explore these relationships, we model the effects of three alternative development scenarios on annual average fine particulate matter (PM2.5) concentrations in ambient air and associated health risks from PM2.5 exposure in North Carolina's Raleigh‐Durham‐Chapel Hill area. We integrate transportation demand, land‐use regression, and health risk assessment models to predict air quality and health impacts for three development scenarios: current conditions, compact development, and sprawling development. Compact development slightly decreases (?0.2%) point estimates of regional annual average PM2.5 concentrations, while sprawling development slightly increases (+1%) concentrations. However, point estimates of health impacts are in opposite directions: compact development increases (+39%) and sprawling development decreases (?33%) PM2.5‐attributable mortality. Furthermore, compactness increases local variation in PM2.5 concentrations and increases the severity of local air pollution hotspots. Hence, this research suggests that while compact development may improve air quality from a regional perspective, it may also increase the concentration of PM2.5 in local hotspots and increase population exposure to PM2.5. Health effects may be magnified if compact neighborhoods and PM2.5 hotspots are spatially co‐located. We conclude that compactness alone is an insufficient means of reducing the public health impacts of transportation emissions in automobile‐dependent regions. Rather, additional measures are needed to decrease automobile dependence and the health risks of transportation emissions.  相似文献

The grounds for official policy claims that environmental tobacco smoke is a major health risk remain speculative. In scientific terms, the evidence is compatible with either a slight increase or a decrease of risks, but is impotent to certify either conclusion. Official advocacy of unproven hypotheses presented as valid scientific conclusions raises serious ethical questions, and threatens the credibility of risk assessment as a legitimate policy instrument.  相似文献

Researchers investigating human settlements from an archaeological perspective have long recognized that the urban landscape provides a particular set of challenges and demands. Building on the formative Arup study [Ove Arup and Partners (1991) York Development and Archaeology Study (London: English Heritage)], urban deposit modelling as a heritage planning tool has been developed for some time; however, its use has not become widespread. There are however recent intellectual and technical developments that enhance integrated deposit modelling and reveal potential as a curatorial tool for the management of the historic environment. These relate to three key developments: the improvement and enhancement of 3D modelling and visualization techniques, conceptual changes around categories such as ‘made ground’ and the formation of research agendas for the urban historic environment. This paper will explore an example of the difficulties inherent in combining differently scaled datasets whilst also outlining the potential and the significance of urban deposit modelling in, often deeply stratified, historic northern European cities.  相似文献

The number of people with dementia worldwide will reach 115.4 million by 2050. This accelerating crisis has sparked research on how to design neighbourhoods for those with early dementia, and how to empower them through built environment changes to remain in their community for as long as possible. There are numerous benefits for persons with dementia who continue access to their neighbourhood: physical activity, sense of dignity, social interaction, autonomy and psychological wellbeing. In this paper, I examine 17 recommendations (urban design and land use strategies) identified as ‘dementia-friendly’, within dementia design and planning literature. Each is then examined against the planning frameworks for a mid-size suburban municipality in Ontario and assessed for its financial impact on a base case subdivision using pro forma analysis. The effect on the financial return for a developer was minimal, demonstrating that establishing these recommendations as policy is viable, through regulation and incentives.  相似文献

This article discusses the relationship between globalization, the state, and public administration, with implications for developmental states. Using a political economy analysis, globalization is discussed as the latest dynamic change in the context of the continuity within the process of surplus accumulation by corporate capitalism at the global level, a phenomenon with far reaching implications for the modern state, governance, and public administration. First, the context of change and continuity is briefly discussed, followed by a presentation of several theoretical perspectives on, and meanings of, globalization as defined by different people from different disciplines. Then, the causes and consequences of globalization are discussed with implications for the state and public administration. Finally, a number of policy choices are suggested in response to globalization by developmental states, with another discussion on the changing character and role of the state under globalization with implications for the state and public administration worldwide.  相似文献

Abstract

There has been little attempt to situate notions of competence historically or culturally and the definition of competence has not changed much once applied to different national workforce development policies. An international group of scholars examines this topic as one of the products of HRD research and practice and notes the need to recontextualize the construct of competence within social, political and cultural practices.  相似文献

The exercise of administrative discretion is inevitable in complex policy-making and law enforcement, including immigration policy generally and the Elian Gonzalez case specifically. Clearly, discretion is in tension with democratic notions of political accountability, the rule of law, and constitutional separation of powers. Yet the Elian case suggests that although discretion poses a threat to democracy it also contributes to a democratic public administration. Furthermore, because discretion is exercised in a sea of safeguards its dangers can be reconciled to its necessity.  相似文献

Although the term ‘quality’ has a universal positive connotation and typically is framed by a focus on improvements, its application includes as well as excludes the access, values and world views of particular actors and interests. In this article, we highlight the relevance and implications of such ‘inherent politics’ through a case study of a widespread approach to operationalizing quality in urban green space management. We conclude that adoption of any quality model has both limiting and enabling implications for public participation and decision-making and that a critical stance is needed within both research and practice for the development of quality models that connect to values of broader societal relevance.  相似文献

This paper describes a multi-stakeholder process designed to assess the potential health risks associated with adverse air quality in an urban industrial neighborhood. The paper briefly describes the quantitative health risk assessment conducted by scientific experts, with input by a grassroots community group concerned about the impacts of adverse air quality on their health and quality of life. In this case, rather than accept the views of the scientific experts, the community used their powers of perception to advantage by successfully advocating for a professionally conducted community health survey. This survey was designed to document, systematically and rigorously, the health risk perceptions community members associated with exposure to adverse air quality in their neighborhood. This paper describes the institutional and community contexts within which the research is situated as well as the design, administration, analysis, and results of the community health survey administered to 402 households living in an urban industrial neighborhood in Hamilton, Ontario, Canada. These survey results served to legitimate the community's concerns about air quality and to help broaden operational definitions of health. In addition, the results of both health risk assessment exercises served to keep issues of air quality on the local political agenda. Implications of these findings for our understanding of the environmental justice process as well as the ability of communities to influence environmental health policy are discussed.  相似文献

Differences in the context of developed vs. developing countries require different kinds of urban planning skills in each group. This paper intends to figure out the most important skills an urban planner should have in a developing country. A total of 341 questionnaires were filled by professionals, instructors, students, and graduates. The result shows that team work, research method and data collection, and technical skills are the most important skills at the undergraduate level, in Iran, while problem definition, analytical skills, and oral presentation are the most important ones at the graduate level. Managerial skills, at neither level, show any significance.  相似文献

We analyze the issue of agency costs in aviation security by combining results from a quantitative economic model with a qualitative study based on semi‐structured interviews. Our model extends previous principal‐agent models by combining the traditional fixed and varying monetary responses to physical and cognitive effort with nonmonetary welfare and potentially transferable value of employees' own human capital. To provide empirical evidence for the tradeoffs identified in the quantitative model, we have undertaken an extensive interview process with regulators, airport managers, security personnel, and those tasked with training security personnel from an airport operating in a relatively high‐risk state, Turkey. Our results indicate that the effectiveness of additional training depends on the mix of “transferable skills” and “emotional” buy‐in of the security agents. Principals need to identify on which side of a critical tipping point their agents are to ensure that additional training, with attached expectations of the burden of work, aligns the incentives of employees with the principals' own objectives.  相似文献

This paper considers the process and dynamics of reurbanisation and its implications for metropolitan planning. After brief consideration of reurbanisation trends in the UK, through a case study of the city of Liverpool in North West England, the paper explores how these recent trends of population regrowth and changing patterns of housing production (including purpose-built student accommodation) have affected the social structure of the city and what are the implications for planning policy? The paper concludes that population regrowth has been associated with increased spatial social segregation but is likely to continue and will shape future metropolitan planning.  相似文献

Effective control and eradication of diseases requires reliable information from surveillance activities, including laboratories, which typically incur real financial costs. This article presents data from a survey we conducted to estimate the costs of the Global Polio Laboratory Network (GPLN), which currently supports aggressive global surveillance for acute flaccid paralysis (AFP) to detect circulating polioviruses. The Global Polio Eradication Initiative (GPEI) of the World Health Organization (WHO) provides resources for some of the laboratory network costs, but the total cost of the network remains relatively poorly characterized given the limited documentation of national contributions. We surveyed network laboratories to quantify AFP surveillance support costs and provide data for cost estimates of potential posteradication surveillance policies related to the laboratories. We estimate that the GPLN currently requires millions (US dollars 2002) in total support annually, and that half of the support for national and regional reference laboratories comes from external donors through the WHO or bilateral agreements and half from within nations that host those laboratories. The article also presents the framework for considering the value of information from this global surveillance network and suggests that the expected value of surveillance information from the GPLN currently exceeds its costs. We also provided important insights about how the value of information may change after successful eradication of wild polioviruses.  相似文献

Wildfires in the wildland urban interface (WUI) are an increasing concern throughout the western United States and elsewhere. WUI communities continue to grow and thus increase the wildfire risk to human lives and property. Information such as a wildfire risk map can inform WUI residents of potential risks and may help to efficiently sort mitigation efforts. This study uses the survey-based contingent valuation (CV) method to examine annual household willingness to pay (WTP) for the provision of a wildfire risk map. Data were collected through a mail survey of the East Mountain WUI area in the State of New Mexico (USA). The integrated empirical approach includes a system of equations that involves joint estimation of WTP values, along with measures of a respondent's risk perception and risk mitigation behavior. The median estimated WTP is around U.S. $12 for the annual wildfire risk map, which covers at least the costs of producing and distributing available risk information. Further, providing a wildfire risk map can help address policy goals emphasizing information gathering and sharing among stakeholders to mitigate the effects of wildfires.  相似文献

The New Public Management (NPM) has often been favorably contrasted with European Public Administration (EPA). This paper attempts to balance this Anglo-American perspective with a relatively new European critique of NPM which its authors call the Neo-Weberian State (NWS). Despite their differences in some key respects, however, it is argued that the NPM and NWS are similar in their sweeping paradigmatic character, their ambiguities and internal inconsistencies, their inability to go beyond instrumental rationality and incorporate forms of hermeneutic and critical reason, and in their advocacy of bureaucracy via participation under certain historical conditions, hence consistent with Weber’s characterization of modern organization and management. The paper, based on the authors’ rendering of critical social theory, provides a fresh means for bridging the two perspectives.

Industrial societies have altered the earth's environment in ways that could have important, long-term ecological, economic, and health implications. In this paper, we examine the extent to which uncertainty about global climate change could impact the precision of predictions of secondary outcomes such as health impacts of pollution. Using a model that links global climate change with predictions of chemical exposure and human health risk in the Western region of the United States of America (U.S.), we define parameter variabilities and uncertainties and we characterize the resulting outcome variance. As a case study, we consider the public health consequences from releases of hexachlorobenzene (HCB), a ubiquitous multimedia pollutant. By constructing a matrix that links global environmental change both directly and indirectly to potential human-health effects attributable to HCB released into air, soil, and water, we define critical parameter variances in the health risk estimation process. We employ a combined uncertainty/sensitivity analysis to investigate how HCB releases are affected by increasing atmospheric temperature and the accompanying climate alterations that are anticipated. We examine how such uncertainty impacts both the expected magnitude and calculational precision of potential human exposures and health effects. This assessment reveals that uncertain temperature increases of up to 5°C have little impact on either the magnitude or precision of the public-health consequences estimated under existing climate variations for HCB released into air and water in the Western region of the U.S.  相似文献

This article examines the degree of autonomy of Hong Kong’s Airport Authority (AA). Traditionally, airport management in Hong Kong was the responsibility of the government’s Civil Aviation Department. The AA was established in 1995 to manage the new international airport at Chek Lap Kok which opened in 1998. It was expected to run as a commercial enterprise but, because of its strategic importance, there was concern that it should not become an independent empire detached from government control. As a hybrid type of organization, the AA has moved steadily towards full commercialization. The government has also put its privatization on the agenda. Its transformation may have some implications for the redefinition of the future autonomy boundaries of public corporations in Hong Kong.

Because of the high emissions of polycyclic aromatic hydrocarbons (PAHs) into the environment by the increasing number of vehicles in Beijing and the absorption of these PAHs onto particulates, the performance of a preliminary health risk assessment of the aggregate exposure to PAHs of urban citizens in daily life is very important. Urban dust can be used to examine the aggregation of atmospheric particulates from local pollution sources over a long time period and the direct exposure of the urban human population. The environment's correlative with clothing, dining, residing, and traveling in urban daily life was assessed using exposure‐receptor‐oriented analysis. The multipathway exposure model was used to simulate the lifetime exposure of a female citizen to PAHs in dust. All of the PAH concentrations in dust for each behavior and its correlative environment in Beijing were acceptable because all of the carcinogenic risks of PAHs in the dust were approximately 1.0 × 10–6. The dominant induced carcinogenic risks in the dust were Benzo(a)pyrene and Dibenzo(a,h)anthracene. The main carcinogenic risk routes for humans were dermal contact and oral intake, which contributed on average 99.78% of the risk. Indoor risk is especially important, as the decoration and height within the building were important impact factors for carcinogenic risk induced by indoor PAHs. For people living in an urban area, a healthy lifestyle includes less decoration per room, living on a low floor, wearing a respirator, and reducing exposed skin area when traveling.  相似文献

The aim of this paper is to shed light on the cognitive as well as the disciplinary role of one important governance mechanism that is the board of directors in a privatization context. Using a sample of privatized French companies, we examine the relationship between the size, component and structure of this mechanism to the performance and value creation on the post privatization period. Thus, the majority of our findings have support on the theory of cognitive governance, one aspect of governance that was ignored in previous research.  相似文献
