  17. Truck transport of RAM: Risk effects of avoiding metropolitan areas

    SciTech Connect

    Mills, G.S.; Neuhauser, K.S.

    1997-11-01

    In the transport of radioactive material (RAM), e.g., spent nuclear fuel (SNF), stakeholders are generally most concerned about risks in high population density areas along transportation routes because of the perceived high consequences of potential accidents. The most significant portions of a transcontinental route and an alternative examined previously were evaluated again using population density data derived from US Census Block data. This method of characterizing population that adjoins route segments offers improved resolution of population density variations, especially in high population density areas along typical transport routes. Calculated incident free doses and accident dose risks for these routes, and the rural, suburban and urban segments are presented for comparison of their relative magnitudes. The results indicate that modification of this route to avoid major metropolitan areas through use of non-Interstate highways increases total risk yet does not eliminate a relatively small urban component of the accident dose risk. This conclusion is not altered by improved resolution of route segments adjoining high density populations.

    The safety of magnetically levitated (maglev) and high speed rail (HSR) trains proposed for application in the United States is the responsibility of the Federal Railroad Administration (FRA). Plans for near future US applications include maglev technology (e.g. in Orlando, FL and Pittsburgh, PA) and high speed rail (e.g. the French Train a Grande Vitesse (TGV) in the Texas Triangle, between Dallas-Fort Worth, Houston and San Antonio, and along five designated high speed corridors). Concerns exist regarding the potential safety, environmental and health effects on the public and on transportation workers due to electrification along new or existing rail corridors, and to maglev and high speed rail operations. Therefore, the characterization of electric and magnetic fields (EMF) produced by both steady (dc) and alternating currents (ac) at power frequency (50 Hz in Europe and 60 Hz in the U.S.) and above, in the Extreme Low Frequency (ELF) range (3-3000 Hz) is of interest. An EMF survey of the Washington Metrorail (WMATA) transit system was performed, as part of a comprehensive comparative EMF safety assessment of the German Transrapid (TR-07) maglev system with other existing and advanced rail systems. The report provides the Analysis (Vol. I) of results, and detailed data and statistical summaries (Vol. II, Appendices) of representative EMF profiles on vehicles and facilities typical of this transit electrotechnology (third rail dc). EMF data represent a range of train operating conditions and locations (in vehicles, stations and waysides), as well as in traffic control and electrical power supply facilities.

  2. The Transportation Energy and Carbon Footprints of the 100 Largest U.S. Metropolitan Areas

    SciTech Connect

    Southworth, Frank; Sonnenberg, Anthon; Brown, Marilyn A

    2008-01-01

    We present estimates of the automobile and truck travel based energy and carbon footprints of the largest 100 U.S. metropolitan areas. The footprints are based on the estimated vehicle miles traveled and the transportation fuels consumed. Results are presented on an annual basis and represent end use emissions only. Total carbon emissions, emissions per capita, and emissions per dollar of gross metropolitan product are reported. Two years of annual data were examined, 2000 and 2005, with most of the in-depth analysis focused on the 2005 results. In section 2 we provide background data on the national picture and derive some carbon and energy consumption figures for the nation as a whole. In section 3 of the paper we examine the metropolitan area-wide results based on the sums and averages across all 100 metro areas, and compare these with the national totals and averages. In section 4 we present metropolitan area specific footprints and examine the considerable variation that is found to exist across individual metro areas. In doing so we pay particular attention to the effects that urban form might have on these differences. Finally, section 5 provides a summary of major findings, and a list of caveats that need to be borne in mind when using the results due to known limitations in the data sources used.

  3. Comparison of life-cycle energy and emissions footprints of passenger transportation in metropolitan regions

    NASA Astrophysics Data System (ADS)

    Chester, Mikhail V.; Horvath, Arpad; Madanat, Samer

    2010-03-01

    A comparative life-cycle energy and emissions (greenhouse gas, CO, NO X, SO 2, PM 10, and VOCs) inventory is created for three U.S. metropolitan regions (San Francisco, Chicago, and New York City). The inventory captures both vehicle operation (direct fuel or electricity consumption) and non-operation components (e.g., vehicle manufacturing, roadway maintenance, infrastructure operation, and material production among others). While urban transportation inventories have been continually improved, little information exists identifying the particular characteristics of metropolitan passenger transportation and why one region may differ from the next. Using travel surveys and recently developed transportation life-cycle inventories, metropolitan inventories are constructed and compared. Automobiles dominate total regional performance accounting for 86-96% of energy consumption and emissions. Comparing system-wide averages, New York City shows the lowest end-use energy and greenhouse gas footprint compared to San Francisco and Chicago and is influenced by the larger share of transit ridership. While automobile fuel combustion is a large component of emissions, diesel rail, electric rail, and ferry service can also have strong contributions. Additionally, the inclusion of life-cycle processes necessary for any transportation mode results in significant increases (as large as 20 times that of vehicle operation) for the region. In particular, emissions of CO 2 from cement production used in concrete throughout infrastructure, SO 2 from electricity generation in non-operational components (vehicle manufacturing, electricity for infrastructure materials, and fuel refining), PM 10 in fugitive dust releases in roadway construction, and VOCs from asphalt result in significant additional inventory. Private and public transportation are disaggregated as well as off-peak and peak travel times. Furthermore, emissions are joined with healthcare and greenhouse gas monetized

    Transportation noise is known to have negative impact on both public health and life quality. This study evaluated the relationship between transportation noise and annoyance levels, and also the difference of annoyance levels in two metropolitan cities based on epidemiologic surveys. Two thousand adult subjects living in Seoul and Ulsan were enrolled by stratified random sampling on the basis of noise maps from July 2015 to January 2016. Individual annoyance in accordance with transportation noise levels in two metropolitan cities were surveyed using an 11-point visual analog scale questionnaire. The results show that transportation noise level was significantly correlated with annoyance in both cities. Logistic regression analysis revealed that the risk of being 'highly annoyed' increased with noise level (Ldn, day-night average sound level) in both cities. After adjusting for age, residence period, sociodemographic factors (sex, education, marriage, income, alcohol, smoking, and exercise) and noise sensitivity, the risk of being 'highly annoyed' was increased with noise levels in both cities. In comparison to those of areas with noise levels below 55 dBA, the adjusted odds ratios of 'highly annoyed' for areas with 55-65 dBA and over 65 dBA were 2.056 (95% confidence interval [CI] 1.225-3.450), 3.519 (95% CI 1.982-6.246) in Seoul and 1.022 (95% CI 0.585-1.785), 1.704 (95% CI 1.005-2.889) in Ulsan, respectively. Based on the results of a population study, we showed that transportation noise levels were significantly associated with annoyance in adults. However, there were some differences between the two cities. In this study, there were differences in transportation noise between the two cities. Seoul has complex noise (traffic and aircraft), compared to single road traffic noise in Ulsan. Therefore, single and complex transportation noise may have different effects on annoyance levels.

    Similar to most large cities, the transportation sector in the Mexico City Metropolitan Area (MCMA) constitutes the largest source of air pollution emissions, which result in significant impacts on human health. Although the majority of MCMA residents use public transportation, the share of trips in private vehicles is rising and these vehicles have become the largest contributor to mobile emissions. To reduce these emissions, there is an urgent need to improve the current fleet, improve the quality of fuels, and modify the paradigm of private car use, by providing clean, safe, efficient and comfortable public transportation options. Here we present the potential human health benefits of a set of five mobile source control measures that span public and private transportation options: Taxi fleet renovation, Hybrid buses, Metro Expansion, and the introduction of low sulfur gasoline and Tier II vehicles. We also discuss the methodology and preliminary results of the analysis of the implementation of the project for a Bus Rapid Transit system in Mexico City, in terms of its impacts on personal exposures, emissions, and public health.

    2015-09-01

    This study analyzed the association between self-reported diagnosis of hearing loss and individual and occupational factors among urban transportation workers in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil. The sample size was calculated by quotas and stratified by occupation (drivers and fare collectors) in the urban transportation companies in Belo Horizonte, Betim, and Contagem. Data were collected with face-to-face interviews and recorded by the interviewers on netbooks. The dependent variable was defined as an affirmative response to the question on prevailing medical diagnosis of hearing loss. The independent variables were organized in three blocks: social and demographic characteristics, lifestyle, and work aspects. Diagnosis of hearing loss was reported by 213 of the 1,527 workers and was associated with age and diagnosis of tinnitus. At the occupational level, hearing loss was associated with history of sick leave, time-on-the-job, and two environmental risks, unbearable noise and whole-body vibration. Measures to prevent hearing loss are needed for urban transportation workers.

  11. Exploring relationships between building and transportation energy use of residents in U.S. metropolitan regions

    NASA Astrophysics Data System (ADS)

    Pede, Timothy J.

    There is much potential to decrease energy consumption in the U.S. by encouraging compact, centralized development. Although many studies have examined the extent to which built environment and demographic factors are related to household energy use, few have considered both building and transportation energy together. We hypothesized that residents living further from city centers, or urban cores, consume more energy for both purposes than their inner city counterparts, resulting in a direct relationship between building and transportation energy usage. This hypothesis was tested with two case studies. The first focused on New York City. Annual building energy per unit of parcels, or tax lots, containing large multi-family structures was compared to the daily transportation energy use per household of traffic analysis zones (TAZs) (estimated with a regional travel demand model). Transportation energy showed a strong spatial pattern, with distance to urban core explaining 63% of variation in consumption. Building energy use was randomly distributed, resulting in a weak negative correlation with transportation energy. However, both correlation with distance to urban core and transportation energy became significant and positive when portion of detached single-family units for TAZs was used as a proxy for building energy. Structural equation models (SEMs) revealed a direct relationship between log lot depth and both uses of energy, and inverse relationship between portion of attached housing units and transportation energy. This supports the notion that sprawling development increases both the building and transportation energy consumption of households. For the second analysis, annual building and automobile energy use per household were estimated for block groups across the 50 most populous U.S. metropolitan regions with Esri Consumer Expenditure Data. Both forms of energy consumption per household were lowest in inner cities and increased at greater distances from

    Migration pattern of organochloro pesticide lindane has been studied in groundwater of metropolitan city Vadodara. Groundwater flow was simulated using the groundwater flow model constructed up to a depth of 60 m considering a three-layer structure with grid size of 40 × 40 × 40 m(3). The general groundwater flow direction is from northeast to south and southwest. The river Vishwamitri and river Jambua form natural hydrologic boundary. The constant head in the north and south end of the study area is taken as another boundary condition in the model. The hydraulic head distribution in the multilayer aquifer has been computed from the visual MODFLOW groundwater flow model. TDS has been computed though MT3D mass transport model starting with a background concentration of 500 mg/l and using a porosity value of 0.3. Simulated TDS values from the model matches well with the observed data. Model MT3D was run for lindane pesticide with a background concentration of 0.5 μg/l. The predictions of the mass transport model for next 50 years indicate that advancement of containment of plume size in the aquifer system both spatially and depth wise as a result of increasing level of pesticide in river Vishwamitri. The restoration of the aquifer system may take a very long time as seen from slow improvement in the groundwater quality from the predicted scenarios, thereby, indicating alarming situation of groundwater quality deterioration in different layers. It is recommended that all the industries operating in the region should install efficient effluent treatment plants to abate the pollution problem.

  13. Evaluation of a Three-Dimensional Chemical Transport Model (PMCAMx) in the Mexico City Metropolitan Area

    Atmospheric aerosols have adverse effects on human health, contribute to the visibility reduction and influence the energy balance of the planet. A three-dimensional chemical transport model (PMCAMx) (Gaydos et al., 2007) is used to simulate the particular matter (PM) mass composition distribution in the Mexico City Metropolitan Area (MCMA). PMCAMx uses the framework of CAMx (ENVIRON, 2002) modelling the processes of horizontal and vertical advection, horizontal and vertical dispersion, wet and dry deposition, and gas-phase chemistry. In addition to the above, PMCAMx includes three detailed aerosol modules: inorganic aerosol growth (Gaydos et al., 2003; Koo et al., 2003a), aqueous-phase chemistry (Fahey and Pandis, 2001), and secondary organic aerosol formation and growth (Koo et al., 2004). The aerosol thermodynamic model ISORROPIA has been improved as it now simulates explicitly the chemistry of Ca, Mg, and K salts and is linked to PMCAMx. The hybrid approach (Koo et al., 2003b) for modelling aerosol dynamics is applied in order to accurately simulate the inorganic components in coarse mode. This approach assumes that the smallest particles are in equilibrium while the condensation/evaporation equation is solved for the larger ones. The new CMU organic aerosol model, which is based on the splitting of the organic aerosol volatility range in discrete bins, is also used. The model predictions are evaluated against the PM and vapour concentration measurements from the MCMA-2003 Campaign (Molina et al., 2007).

    2012-05-30

    Prior to 2008, transfers of radioactive material within the Savannah River Site (SRS) boundary, referred to as onsite transfers, were authorized by Transportation Safety Basis (TSB) documents that only required approval by the SRS contractor. This practice was in accordance with the existing SRS Transportation Safety Document (TSD). In 2008 the Department of Energy Savannah River Field Office (DOE-SR) requested that the SRS TSD be revised to require DOE-SR approval of all Transportation Safety Basis (TSB) documents. As a result, the primary SRS contractor embarked on a multi-year campaign to consolidate old or generate new TSB documents and obtain DOE-SR approval for each. This paper focuses on the challenges incurred during the rewriting or writing of and obtaining DOE-SR approval of all Savannah River Site Onsite Transportation Safety Basis documents.

  6. Atmospheric transport of pesticides in the Sacramento, California, metropolitan area, 1996-1997

    USGS Publications Warehouse

    Majewski, Michael S.; Baston, David S.

    2002-01-01

    Weekly composite, bulk air was sampled with respect to wind speed and direction from January 1996 through December 1997 in one urban and two agricultural locations in Sacramento County, California. The sampling sites were located along a north-south transect, the dominant directions of the prevailing winds. The samples were analyzed for a variety of current-use pesticides, including dormant orchard spray insecticides and rice herbicides. A variety of pesticides were detected throughout the year, predominantly chlorpyrifos, diazinon, and trifluralin. The data obtained during the winter and spring suggest that some pesticides used in agricultural areas become airborne and may be transported into the urban area. Confirmation of this drift is difficult, however, because these three predominant pesticides, as well as other detected pesticides, also are heavily used in the urban environment. The spring data clearly show that molinate and thiobencarb, two herbicides used only in rice production, do drift into the urban environment.

  8. Impact of travel mode shift and trip distance on active and non-active transportation in the São Paulo Metropolitan Area in Brazil

    de Sá, Thiago Hérick; Parra, Diana C.; Monteiro, Carlos Augusto

    2015-01-01

    Background Changes in urban mobility play a major role in transforming metropolitan areas into healthier places. This study quantified the impact of changes in travel mode shift and trip distance on active and non-active transportation of working age adult population of São Paulo. Methods and findings Through different scenarios, we estimated the daily time spent in transportation per inhabitant (divided in active and non-active transportation time) and the proportion of inhabitants accumulating 30 min or more of daily active transportation. The replacement of individual for collective motorized modes in long distance trips (> 1000 m) in combination with the substitution of long for short trips positively impacted all outcomes. Compared to the current situation, there was an increase in the active transportation time (from 19.4 to 26.7 min/inhabitant), which also increased the proportion of adults active for transportation (from 27.6% to 35.4%). Additionally, the non-active transportation time decreased (from 67.0 to 26.2 min/inhabitant), which helped to reduce the total time spent in transportation (from 86.4 to 52.9 min/inhabitant). Conclusion Transport and urban planning policies to reduce individual motorized trips and the number of long trips might produce important health benefits, both by increasing population levels of active transportation and reducing the non-active and the total time of daily trips.

  1. Urban density and the metabolic reach of metropolitan areas: A panel analysis of per capita transportation emissions at the county-level.

    PubMed

    Ergas, Christina; Clement, Matthew; McGee, Julius

    2016-07-01

    We engage a tension in the urban environment literature that positions cities as both drivers of environmental destruction and loci of environmental protection. We argue that the traditional binary view of cities as either harmful or beneficial is too simplistic; we advance a more nuanced understanding of cities to study their internal and external metabolic effects in terms of carbon emissions from on-road transportation at the county-level across the continental United States between 2002 and 2007. First, utilizing satellite imagery from the National Land Cover Database, we create a novel measure of population density by quantifying the number of people per square mile of impervious surface area. Second, we develop a measure of metropolitan adjacency from the rural classifications datasets published by the USDA. In spatial regression models, we find that while higher density reduces emissions, counties that are geographically isolated from metropolitan areas actually have lower per capita emissions, all else equal. We elaborate on the conceptual, methodological, and practical implications of our study in the conclusion.

    2014-02-01

    There is an interaction between land use, transportation, and environment in improving and managing urban quality. One of the concpets to integrate those three aspects is Transit Oriented Development (TOD). It is a concept for managing urban growth in transit corridors which have characteristics of mixed land use, compact, walkability, and development focused around public transit area. This research aims at utilizing GIS to organize, sort, and analyze spatial data including aspects of land use, transportation, and environment. Jabodetabek is a strategic metropolitan area in Indonesia, and consists of DKI Jakarta and the neighboring Bodetabek cities, with more than 27 million population in 2010. Approximately 1,105,000 people are entering Jakarta every workday from the negihboring Bodetabek region. The surge in the number of passenger cars and motorcycles is astonishing. In contrast, the usage of public transport has declined deeply. Public transport infrastructure development without the integration of TOD may not attain the objective of reducing car dependency. This paper discusses the study which was carried out to identify the applicability of TOD principles in Jabodetabek using GIS as a tool to analysis and create model.

  3. Breast and cervical cancer screening among women in metropolitan areas of the United States by county-level commuting time to work and use of public transportation, 2004 and 2006

    PubMed Central

    2010-01-01

    Background Commuting times and behaviors have been associated with a variety of chronic disease outcomes and health behaviors. We examined the relationships between ecologic measures of commuting time and use of public transportation in relation to breast and cervical cancer screening among women in U.S. metropolitan areas who participated in the 2004 and 2006 Behavioral Risk Factor Surveillance System (BRFSS) surveys. Methods Self-reported county of residence was used to classify respondents as residents of metropolitan statistical areas (MSAs). Only BRFSS respondents who resided in the 39 MSAs with a population of ≥ 1.5 million in 2007--representing a total of 337 counties--were included in this analysis. A total of 76,453 women aged ≥ 40 years were included in analyses on mammography. Analyses on Pap testing were limited to women aged ≥18 years with no history of hysterectomy (n = 80,959). Area-based measures of socio-economic status (SES) were obtained by utilizing county-level information from the 2000 U.S. Census. Results With adjustment for age, no important associations were observed between receipt of a recent mammogram and either a county-level measure of commute time or residence in an area where more residents had access to a car. Similarly, women living in counties where at least four percent of the residents used public transportation were as likely to have had a recent mammogram or Pap test compared with women in areas where less than four percent of residents used public transportation. However, women living in counties where < 2% of residents had no access to a car were somewhat more likely to have had a Pap test in the past 3 years than women in areas where ≥ 3% of the residents had no access to a car (87.3% versus 84.5%; p-value for test for trend < 0.01). In multivariate analysis, living in a county with a median commute time of at least 30 minutes was not significantly associated with having had a Pap test in the past 3 years (adjusted

  9. Assessment of Quality Assurance Measures for Radioactive Material Transport Packages not Requiring Competent Authority Design Approval - 13282

    SciTech Connect

    Komann, Steffen; Groeke, Carsten; Droste, Bernhard

    2013-07-01

    The majority of transports of radioactive materials are carried out in packages which don't need a package design approval by a competent authority. Low-active radioactive materials are transported in such packages e.g. in the medical and pharmaceutical industry and in the nuclear industry as well. Decommissioning of NPP's leads to a strong demand for packages to transport low and middle active radioactive waste. According to IAEA regulations the 'non-competent authority approved package types' are the Excepted Packages and the Industrial Packages of Type IP-1, IP-2 and IP-3 and packages of Type A. For these types of packages an assessment by the competent authority is required for the quality assurance measures for the design, manufacture, testing, documentation, use, maintenance and inspection (IAEA SSR 6, Chap. 306). In general a compliance audit of the manufacturer of the packaging is required during this assessment procedure. Their regulatory level in the IAEA regulations is not comparable with the 'regulatory density' for packages requiring competent authority package design approval. Practices in different countries lead to different approaches within the assessment of the quality assurance measures in the management system as well as in the quality assurance program of a special package design. To use the package or packaging in a safe manner and in compliance with the regulations a management system for each phase of the life of the package or packaging is necessary. The relevant IAEA-SSR6 chap. 801 requires documentary verification by the consignor concerning package compliance with the requirements. (authors)

  10. Metropolitan-scale Transport and Dispersion from the New York World Trade Center Following September 11, 2001. Part II: An Application of the CALPUFF Plume Model

    NASA Astrophysics Data System (ADS)

    Gilliam, Robert C.; Huber, Alan H.; Raman, Sethu

    2005-10-01

    Following the collapse of the New York World Trade Center (WTC) towers on September 11, 2001, Local, State, and Federal agencies initiated numerous air monitoring activities to better understand the ongoing impacts of emissions from the disaster. The collapse of the World Trade Center towers and associated fires that lasted for several weeks resulted at times in a noticeable plume of material that was dispersed around the Metropolitan New York City (NYC) area. In general, the plume was only noticeable for a short period of time following September 11, and only apparent close to the World Trade Center site. A study of the estimated pathway which the plume of WTC material would likely follow was completed to support the United States Environmental Protection Agency’s 2002 initial exposure assessments. In this study, the WTC emissions were simulated using the CALMET-CALPUFF model in order to examine the general spatial and temporal dispersion patterns over NYC. This paper presents the results of the CALPUFF plume model in terms of plume dilution and location, since the exact source strength remains unknown. Independent observations of PM2.5 are used to support the general dispersion features calculated by the model. Results indicate that the simulated plume matched well with an abnormal increase (600 1000% of normal) in PM2.5 two nights after the WTC collapse as the plume rotated north to southeast, towards parts of NYC. Very little if any evidence of the plume signature was noted during a similar flow scenario a week after September 11. This leads to the conclusion that other than areas within a few kilometers from the WTC site, the PM2.5 plume was not observable over NYC’s background concentration after the first few days.

  12. Comparison of minimum space allowance standards for transportation of cattle by road from 8 authorities.

    PubMed

    Whiting, T L

    2000-11-01

    Space allowance for animals in transit is a consistent concern in many countries developing codes of practice and regulations to assure humane treatment of food producing animals. Describing minimum space allowance requirements for cattle in transit has proven to be difficult, as the space required increases as the animal grows. Loading pressure, defined as weight of live animal per unit area, has proven to be a clear method of communicating with transporters and inspection staff what the maximum safe stocking limit is based on individual animal weight. The loading density recommendations in the Canadian code of practice for beef cattle are compared with other standards by using loading pressure charts as a visual aid. Loading pressure charts are recommended in preference to a tabular format to describe the minimal space allowed per animal for cattle transported by road.

  2. Emissions inventory for the Mexico City Metropolitan Area

    The emissions inventory bears a broad relationship to the energy balance, reflecting the dependence of the emissions with reference to the use of energy. Actually the consumption of gasoline and diesel fuel in the transport sector represents collectively, the greatest comparative expense of energy and the major contributor of the ozone precursor pollutants HC, NO{sub x} and CO, relative to the total volume of emissions in the Mexico City Metropolitan Area (MCMA). Also, the industrial sector introduces significant emissions of SO{sub 2} and NO{sub x} due to its energy consumption of fuel oils and natural gas. In contrast, the great majority of suspended particulate in the MCMA emanate from degradation processes of surface soil along the periphery of the urban zone. To the federal and local authorities charged with the design of strategies for prevention and control of atmospheric pollution, the emissions inventory is a strategic tool that reflects the relative intensity of the various emitters to the load capacity of the atmosphere. A comprehensive inventory was compiled for 1995, categorizing the emissions generated by four sectors: industry, services, transport and surface soils and vegetation, considering the following pollutants: TSP, SO{sub 2}, NO{sub x}, HC and CO. The combined pollutant emissions are 4,009,628 tons/year of which 3% are generated by the industry, 10% by the services sector, 75% by the transport sector, and 12% by surface soils and vegetation.

  3. Economic impacts of SEPTA on the regional and state economy. Final report. [SouthEast Pennsylvania Transportation Authority

    The report evaluates the economic and social impacts of supporting the Southeast Pennsylvania Transportation Authority (SEPTA) public transportation system. The study is comprehensive, considering travel times and costs for individual travelers, and how those changes would affect the cost of doing business, individual spending patterns, and the regional and State economies. Four alternatives were considered: rehabilitation of the system and continuation of services, a fifty-percent scaleback of services, gradual shutdown of the system over ten years, and immediate shutdown. The analysis showed that rehabilitation of the system would return three dollars to the region for every dollar spent on it, and that cutting back service would have economic costs far greater than any savings accrued. The methodology is general, and can be applied in other areas.

    1984-08-01

    This discussion of the metropolitan area of Sao Paulo, Brazil focuses on: administrative divisions; diversity and population growth; households, fertility, and mortality; migration; ethnicity, race, and religion; housing; transport; labor and income; and consumption. Currently, the metropolitan area of Sao Paulo, or Greater Sao Paula, is considered the 2nd largest urban agglomeration in Latin America after Mexico City. An estimated 9.5 million people live within the 583 square mile area of the central city. Another 5 million people live in 1 of the 36 other municipalities included in the metropolitan area which includes all 37 municipalities. Central city refers to the municipalities of Sao Paulo and Osasco. The city of Sao Paulo refers only to the municipality of Sao Paulo. The metropolitan area contains 3110 square miles in total and is still the smallest of the 11 administrative regions that comprise the State of Sao Paulo. The population, urban infrastructure, and economic activities are unevenly spread among the 37 municipalities. Greater Sao Paulo's population grew an average of 4.5 year during the 1970, down slightly from a peak of 5.9 year in the 1950s. The central city has a current growth rate of 3.7, a year, with the increase concentrated mainly in the southern and eastern districts that are removed from the city center and where land prices are still relatively low. Mortality plays a minor role in the population trends of Sao Paulo. Fertility is now slowly becoming the dominant factors in its natural increase. The average number of children a woman will bear is 3.3 in the metropolitan area and 3 in the city, low compared with the Brazilian national average of 4.2 children. According to a 1978 survey, 60% of the women use some form of birth control. The most common methods are oral contraceptives 27%, and sterilization, 15%. Despite declining fertility, the birthrate of the metropolitan area increased from 26 in 1970 to 30 in 1980 because of the changes

  7. Air pollution holiday effect in metropolitan Kaohsiung

    Different from Taipei, the metropolitan Kaohsiung which is a coastal and industrial city has the major pollution sources from stationary sources such as coal-fired power plants, petrochemical facilities and steel plants, rather than mobile sources. This study was an attempt to conduct a comprehensive and systematical examination of the holiday effect, defined as the difference in air pollutant concentrations between holiday and non-holiday periods, over the Kaohsiung metropolitan area. We documented evidence of a "holiday effect", where concentrations of NOx, CO, NMHC, SO2 and PM10 were significantly different between holidays and non-holidays, in the Kaohsiung metropolitan area from daily surface measurements of seven air quality monitoring stations of the Taiwan Environmental Protection Administration during the Chinese New Year (CNY) and non-Chinese New Year (NCNY) periods of 1994-2010. Concentrations of the five pollutants were lower in the CNY than in the NCNY period, however, that of O3 was higher in the CNY than in the NCNY period and had no holiday effect. The exclusion of the bad air quality day (PSI > 100) and the Lantern Festival Day showed no significant effects on the holiday effects of air pollutants. Ship transportation data of Kaohsiung Harbor Bureau showed a statistically significant difference in the CNY and NCNY period. This difference was consistent with those found in air pollutant concentrations of some industrial and general stations in coastal areas, implying the possible impact of traffic activity on the air quality of coastal areas. Holiday effects of air pollutants over the Taipei metropolitan area by Tan et al. (2009) are also compared.

    Single entry communities (SECs) and cul-de-sacs minimize route choices and increase trip distance. Las Vegas' built environment facilitates the examination of these variables and active transport to school (ATS) rates. The purpose of this study was to examine the influence of SECs and cul-de-sacs on ATS rates in Las Vegas, NV elementary children. Parental-reported data was collected from 11 elementary schools on ATS rates (n = 1217). SECs and cul-de-sacs were quantified for each school zone. Logistic regression models were used to predict ATS. 23.9% of students reported ATS all of the time and 31.4% some of the time. SECs per school zone ranged from 0 to 25 (mean = 11.9). Cul-de-sacs ranged from 12 to 315 (mean = 138.3). Some ATS use was predicted by distance from school (p ≤ 0.001;OR = 0.61), parental education (high school: p = 0.004;OR = 0.53, some college: p = 0.001;OR = 0.50, 4 year degree: p = 0.004;OR = 0.52) and cul-de-sacs (p ≤ 0.001;OR = 0.99). A separate model using distance from school (p ≤ 0.001;OR = 0.61), parental education (high school: p = 0.002;OR = 0.51, some college: p ≤ 0.001;OR = 0.45, 4 year degree: p ≤ 0.001;OR = 0.45) and SECs (p ≤ 0.001;OR = 0.96) predicted some ATS. All ATS use was predicted by distance from school (p ≤ 0.001;OR = 0.58), parental education (Grades 9-11: p = 0.05;OR = 0.61, high school: p ≤ 0.001;OR = 0.45, some college: p ≤ 0.001;OR = 0.41, 4 year degree: p ≤ 0.001;OR = 0.38) and SECs (p ≤ 0.001;OR = 0.97). A separate model using distance from school (p ≤ 0.001;OR = 0.58), parental education (Grades 9-11: p = 0.041;OR = 0.59, high school: p ≤ 0.001;OR = 0.47, some college: p ≤ 0.001;OR = 0.44, 4 year degree: p ≤ 0.001;OR = 0.43) and cul-de-sacs (p ≤ 0.001;OR = 0.99) predicted all ATS. Current findings reveal that both SECs and cul-de-sacs were predictors of ATS beyond distance. Students with

    Contamination of major aquifers in highly densely populated areas is a major concern for stakeholders involved in the use and protection of groundwater resources. Sustainable groundwater withdrawal and management, and the identification of trends in groundwater contamination require a careful hydrochemical baseline characterization. This characterization is fundamental to investigate the presence and evolutionary trend of contaminants. In fact, it allows recovering and understanding: the spatial-temporal trend of contamination; the relative age of the contamination episodes; the reasons for anomalous behavior of some compounds during migration to and in the groundwater; the associations with which some contaminants can be found; the different behaviors in phreatic and semi-confined and confined aquifers. To attain such a characterization for the Milan metropolitan area (about 2,500 km2, ca 4.000.000 inhabitants, Lombardy, Italy), we carried out three main activities. (1) Collection of complete and reliable datasets concerning the geological, hydrogeological and hydrochemical (over 60,000 chemical analysis since 2003 to 2013) characteristics of the area and of the involved aquifers. This activity was very demanding because the available data are provided by different authorities (Lombardy Region, Provinces, Lombardy Environmental Agency - ARPA Lombardia, public own companies in charge of water system managements) in raw format and with different database standard, which required a large effort of manual verification and harmonization. (2) Completion of a hydrochemical characterization of the metropolitan area aquifers by classical statistical and multivariate statistical analyses, in order to define a baseline both for some major physical chemical characteristics and for the most relevant contaminants. (3) Development of a three dimensional hydrogeological model for the metropolitan area starting from the above listed datasets and existing models. This model will

    Ozone in the main air pollutant in Mexico City Metropolitan Area (MCMA). This kind of pollution is induced by the emissions of nitrogen oxides and hydrocarbons. According to Official Statistics National Air Pollution Quality Standard is exceeded over 300 days a year. Volatile hydrocarbons are generated in the cycle of storage transport and distribution of fuel (Gasoline Distribution Cycle). Above 17 millions of liters are handled daily in MCMA. Evaporative emission control is a complex task involving: floating roof tanks and vapor recovery units installation at bulk terminals and implementation of Phase 1 and Phase 2 vapor recovery systems at service stations. Since 1990, IMP has been involved in researching vapor emissions associated to gasoline storage and distribution cycle. Besides, the authors evaluate several technologies for bulk terminals and service stations. In this job, the authors present the results of an evaluation according to Mexican Official Standard of 500 vehicles. The gasoline vapors are trapped during refueling of cars and they are conduced to an equipment that includes an activated charcoal canister in order to adsorb them. Another Activated charcoal canister adsorbs ambient air as a reference. Experimental results showed that refueling hydrocarbon emissions are between 0.4 and 1.2 grams per liter with averages of 0.79 and 0.88 grams per liter according with two different gasoline types. These results were applied to Mexico City Vehicular fleet for the gasoline distribution cycle in order to obtain a total volatile hydrocarbon emission in Mexico City Metropolitan Area.

    The purpose of the study was to examine professionals' awareness, knowledge, and experiences working with youth victims of sex trafficking in metropolitan and non-metropolitan communities. Professionals who worked with at-risk youth and/or crime victims were recruited from all counties in a southern, rural state in the U.S. to complete a telephone survey. Surveys included closed and open-ended questions, which were theme coded. Professionals' (n=289) were classified into one of four categories based on the counties in which they worked: metropolitan, micropolitan, rural, and all three community types. Although there were many similarities found in trafficking situations across the different types of communities, some expected differences were found. First, as expected, more professionals in metropolitan communities perceived CSEC as being a fairly or very serious problem in the state overall. Consistent with other studies, more professionals in metropolitan communities had received training on human trafficking and reported they were familiar with the state and federal laws on human trafficking (Newton et al., 2008). Significantly more professionals in metropolitan (54.7%) communities reported they had worked with a suspected or definite victim of STM compared to professionals in micropolitan communities (29.8%). There were few differences in victim characteristics, vulnerability factors, and trafficking situations (e.g., relationship to trafficker, traffickers' techniques for controlling victims, transportation, and Internet-facilitation of trafficking) across the community types. There is a continued need for awareness building of STM and training, particularly in non-metropolitan communities, as well as adoption of screening tools, integration of trauma-informed care, and identification of best practices.

    2009-01-01

    Objectives. We investigated the frequency with which alcohol advertisements appeared on Massachusetts Bay Transportation Authority (MBTA) transit lines in Boston, MA, and we calculated adult and youths' exposure to the ads. Methods. We measured the nature and extent of alcohol advertisements on 4 Boston transit lines on 2 separate weekdays 1 month apart in June and July of 2008. We calculated weekday ad exposure for all passengers (all ages) and for Boston Public School student passengers (aged 11–18 years). Results. Alcohol ads were viewed an estimated 1 212 960 times across all Boston-area transit passengers during an average weekday, reaching the equivalent of 42.7% of that population. Alcohol ads were viewed an estimated 18 269 times by Boston Public School student transit passengers during an average weekday, reaching the equivalent of 54.1% of that population. Conclusions. Advertisers reached the equivalent of half of all Boston Public School transit passengers aged 11 to 18 years and the equivalent of nearly half of all transit passengers in the Boston area with an alcohol advertisement each day. Because of the high exposure of underage youths to alcohol advertisements, we recommend that the MBTA prohibit alcohol advertising on the Boston transit system. PMID:19890170

  16. Metropolitan population growth in Arab countries.

    PubMed

    Vaidyanathan, K E

    1977-01-01

    A study or urban population growth in Arab countries has 3 objectives: 1) examination at the micro level of recent demographic trends in selected metropolitan areas of the Arab world and their relationship to changes in the total and urban populations in the respective countries; 2) estimation of net migration by sex and broad age groups for each metropolitan area; and 3) analysis of the pattern of variation in the metropolitan growth rates and their components, migration and natural increase. The study covers the cities proper or urban agglomerations, which includes the suburbs, whose population exceeded 100,000 in the most recent census. Altogether, the study covers 49 metropolitan areas from 9 Arab countries--Algeria; Morocco; Tunisia; Libya; Egypt; Sudan; Syria; Iraq; and Kuwait. Analysis revealed that metropolitan growth rates do follow geographic patterns. In countries with an oil-based economy, metropolitan growth rates are high; in countries with unexploited resources they are slightly below the 1st group; and countries which have pressure on land have low metropolitan growth rates. Population size of the metropolitan area appears to be an important factor associated with variations in metropolitan growth rates and net migration rates. Natural increase emerges as the predominant factor in metropolitan growth, but the differentials in the growth rates are more clearly associated with variations in net migration rates. As all the possibilities of analysis of relationships of metropolitan growth have not been exhausted, it is proposed to examine additional variables as possible factors associated with the speed of metropolitan growth.

  11. Suburbanization and sustainability in metropolitan Moscow.

    PubMed

    Mason, Robert J; Nigmatullina, Liliya

    2011-01-01

    Although Soviet-era urban-growth controls produced relatively sustainable metropolitan development patterns, low-density suburban sprawl has accelerated markedly in modern Russia. Distinctive features of Moscow's development history are its greenbelt, which dates from 1935 and is becoming increasingly fragmented, proliferation of satellite cities at the urban fringe, conversion of seasonal dachas into full-time residences, the very exclusive Rublevo Uspenskoe Highway development, and today's crippling traffic congestion. The recent economic crisis has slowed development and actually increased the supply of “economy-class” single-family homes, for which there is much pent-up desire but insufficient credit availability to meet the demand. A renewed commitment to sustainability's triple bottom line—environmental quality, equity, and economic prosperity—will require greater government transparency and fairness, stronger planning controls, and an expanded public transportation system.

    The air quality in mass transport buses, especially air-conditioned buses may affect bus drivers who work full time. Bus numbers 16, 63, 67 and 166 of the Seventh Bus Zone of Bangkok Mass Transit Authority were randomly selected to investigate for microbial air quality. Nine air-conditioned buses and 2-4 open-air buses for each number of the bus (36 air-conditioned buses and 12 open-air buses) were included. Five points of in-bus air samples in each studied bus were collected by using the Millipore A ir Tester Totally, 180 and 60 air samples collected from air-conditioned buses and open-air buses were cultured for bacterial and fungal counts. The bus drivers who drove the studied buses were interviewed towards histories of work-related illness while working. The results revealed that the mean +/- SD of bacterial counts in the studied open-air buses ranged from 358.50 +/- 146.66 CFU/m3 to 506 +/- 137.62 CFU/m3; bus number 16 had the highest level. As well as the mean +/- SD of fungal counts which ranged from 93.33 +/- 44.83 CFU/m3 to 302 +/- 294.65 CFU/m3; bus number 166 had the highest level. Whereas, the mean +/- SD of bacterial counts in the studied air-conditioned buses ranged from 115.24 +/- 136.01 CFU/m3 to 244.69 +/- 234.85 CFU/m3; bus numbers 16 and 67 had the highest level. As well as the mean +/- SD of fungal counts which rangedfrom 18.84 +/- 39.42 CFU/m3 to 96.13 +/- 234.76 CFU/m3; bus number 166 had the highest level. When 180 and 60 studied air samples were analyzed in detail, it was found that 33.33% of the air samples from open-air buses and 6.11% of air samples from air-conditioned buses had a high level of bacterial counts (> 500 CFU/m3) while 6.67% of air samples from open-air buses and 2.78% of air samples from air-conditioned buses had a high level of fungal counts (> 500 CFU/m3). Data from the history of work-related illnesses among the studied bus drivers showed that 91.67% of open-air bus drivers and 57.28% of air-conditioned bus drivers had

  18. Set of Comparable Carbon Footprints for Highway Travel in Metropolitan America

    SciTech Connect

    2011-01-01

    The authors describe the development of a set of carbon dioxide emissions estimates for highway travel by automobile, truck, bus and other public transit vehicle movements within the nation s 100 largest metropolitan areas, in calendar year 2005. Considerable variability is found to exist across metropolitan areas when these greenhouse gas emissions are measured on a per capita and a per gross metropolitan product (GMP) basis. Least square regression modeling shows a relationship between emissions per capita and per GMP with truck traffic share, transit share, employment density, population dispersion within the metro area, and GMP per capita. As a result many of the nation s largest metropolitan areas tend to have lower CO2 emissions per capita and per GMP than smaller and more recently developed metro areas.

    2013-12-01

    Flood is one of the most significant natural hazards in Japan. The Tokyo metropolitan area has been affected by several large flood disasters. Therefore, investigating potential flood risk in Tokyo metropolitan area is important for development of adaptation strategy for future climate change. We aim to develop a method for evaluating flood risk in Tokyo Metropolitan area by considering effect of historical land use and land cover change, socio-economic change, and climatic change. Ministry of land, infrastructure, transport and tourism in Japan published 'Statistics of flood', which contains data for flood causes, number of damaged houses, area of wetted surface, and total amount of damage for each flood at small municipal level. By using these flood data, we estimated damage by inundation inside a levee for each prefecture based on a statistical method. On the basis of estimated damage, we developed flood risk curves in the Tokyo metropolitan area, representing relationship between damage and exceedance probability of flood for the period 1976-2008 for each prefecture. Based on the flood risk curve, we attempted evaluate potential flood risk in the Tokyo metropolitan area and clarify the cause for regional difference of flood risk. By analyzing flood risk curves, we found out regional differences of flood risk. We identified high flood risk in Tokyo and Saitama prefecture. On the other hand, flood risk was relatively low in Ibaraki and Chiba prefecture. We found that these regional differences of flood risk can be attributed to spatial distribution of entire property value and ratio of damaged housing units in each prefecture.We also attempted to evaluate influence of climate change on potential flood risk by considering variation of precipitation amount and precipitation intensity in the Tokyo metropolitan area. Results shows that we can evaluate potential impact of precipitation change on flood risk with high accuracy by using our methodology. Acknowledgments

    1985-01-01

    The similarities and differences between areas inside and outside U.S. metropolitan areas were evaluated in terms of their commercial/industrial and government employment characteristics. The comparison focuses on the levels, shares, and composition of employment in the commercial/industrial and government sectors that represent potential classes of land mobile communications users. The major findings of the analysis are as follows: (1) non-metropolitan commercial/industrial user classes of land mobile communication services exist in significant numbers; (2) the compositions of non-metropolitan and metropolitan commercial/industrial user classes of land mobile communication services closely resemble each other; (3) non-metropolitan areas have significant levels of the government user classes that represent potential markets for land mobile communication services; and (4) non-metropolitan local governments have a significantly larger proportion of their employment in the primary user classes of private land mobile radio service than do metropolitan local governments.

    OBJECTIVE To analyze the correlation between sociodemographic factors and working conditions of bus workers in a metropolitan area and violence against them. METHODS This cross-sectional study used a nonprobabilistic sample estimated according to the number of workers employed in bus companies located in three cities in the Belo Horizonte metropolitan region in 2012 (N = 17,470). Face-to-face interviews were conducted using a digital questionnaire. The factors associated with violence were analyzed in two stages using Poisson regression, according to each level. The magnitude of the association was evaluated using prevalence ratios with robust variance and a statistical significance of 5%, and 95% confidence intervals were obtained. RESULTS The study sample comprised 782 drivers and 691 fare collectors; 45.0% participants reported at least one act of violence in the workplace in the last 12 months, with passengers being predominantly responsible. The age of the bus workers was inversely associated with violence. Chronic diseases, sickness absenteeism, and working conditions were also associated with violence. CONCLUSIONS The findings on the correlation between violence and working conditions are essential for implementing prevention strategies by transportation service managers. PMID:25741657

  10. Spatial variations in US poverty: beyond metropolitan and non-metropolitan.

    PubMed

    Wang, Man; Kleit, Rachel Garshick; Cover, Jane; Fowler, Christopher S

    2012-01-01

    Because poverty in rural and urban areas of the US often has different causes, correlates and solutions, effective anti-poverty policies depend on a thorough understanding of the ruralness or urbanness of specific places. This paper compares several widely used classification schemes and the varying magnitudes of poverty that they reveal in the US. The commonly used ‘metropolitan/non-metropolitan’ distinction obscures important socioeconomic differences among metropolitan areas, making our understanding of the geography of poverty imprecise. Given the number and concentration of poor people living in mixed-rural and rural counties in metropolitan regions, researchers and policy-makers need to pay more nuanced attention to the opportunities and constraints such individuals face. A cross-classification of the Office of Management and Budget’s metro system with a nuanced RUDC scheme is the most effective for revealing the geographical complexities of poverty within metropolitan areas.

    2016-12-01

    Improving the performance of electronic and optoelectronic components has enabled the investigation of transmitting optical channels with data rates greater than 40 Gb/s, over infrastructures that were initially supporting 10 Gb/s transport. However, for transporting high capacity channels, over long distances, considerable signal processing is necessary, with current emphasis being on digital techniques. Meanwhile in the context of optical networking where spectrally adjacent channels may cross different routes to interconnect the same source destination nodes, adaptive transmission systems become vital. This paper will suggest, compare and develop the necessary transponder technologies that enable transportation of 40 Gb/s channels over deployed Metropolitan Area optical Networks (MAN) infrastructure with emphasis on the interplay between realistic performance, feasibility and complexity/cost. Specifically it will investigate utilizing deployed optical infrastructure for transporting 40 Gb/s DQPSK channels in conjunction with various high performance, low complexity electronic equalizers that can compensate the corresponding linear impairment enhancement that accompanies this upgrade, namely Chromatic Dispersion and Polarization Mode Dispersion while they can be implemented in a single FPGA. It is shown that resource constraint performance evaluation is vital and the exact technology choice is related to the deployed infrastructure.

  18. Evaluation of WRF-CHEM Model: A case study of Air Pollution Episode in Istanbul Metropolitan

    2014-05-01

    Istanbul is the largest city in Europe with a population of about 14 million and nearly 3.2 million registered vehicles. Considering that the city is at the junction of major transportation routes on both land and sea, emissions from all motor vehicles operating in the city and those that are in transit is the major source of pollution. The natural gas is used as the major heat source and the impact of other heating sources on the pollution episodes is not clearly known. During 19-29 December 2013 İstanbul metropolitan area experienced a severe PM10 episode with average episode concentration of 127µgm-3 . The episode was associated with a high pressure system with center pressure of 1030 mb residing over Balkans and north of Black Sea and thereby influencing Istanbul. We carried out simulations using the Weather Research and Forecasting model with Chemistry (WRF-CHEM) v3.5 to examine the meteorological conditions and to produce estimates of PM10 over Istanbul for 17-31 December 2013. The three nested domains was setup using 18, 6 and 2 km horizontal grid spacing with (90x90), (115x115) and (130x130) grid points in 1st, 2nd and 3rd domains, respectively. The each domain was run using one way nesting option after preparing the results from the mother domain as an input to subsequent inner domain. 34 vertical levels were used with the lowest layer depth of 15 m above the surface and extending to 15 km at the model top. The model was configured using the model options after many tests to find optimal model parameters and was initialized using global emissions data available publicly. The local emissions database is still in works and is not available to use in the model instead of global data. The estimated PM10 concentrations were compared against the observed conditions. This work shows the first attempt of using WRF-CHEM in Turkey to estimate the pollutant concentrations instead of using other air pollution models such as WRF/CMAQ combination. At the time of

    1990-06-01

    Florida's Orlando metropolitan area, which has a population measuring 1 million, is among the fastest growing areas in the nation. The city's weather and popular attractions draw 9 to 10 million tourists annually, half of them arriving in their own cars. Add to this the 1.1 million automobiles already on the streets, and the traffic problems become a nightmare. The Orlando metropolitan area has approximately 550 operational traffic signals, with an increasing number of new signals added each year to control the city's expanding growth. A central, computerized signal system has been conceived as one of the solutions necessary to cope with this tremendous traffic growth. The system is flexible, expandable, and capable of meeting future technical challenges. This article describes the steps that led to the feasibility study, design, and implementation of the Orlando area computerized signal system.

    2015-10-06

    Most large cities are spanned by more than one transportation system. These different modes of transport have usually been studied separately: it is however important to understand the impact on urban systems of coupling different modes and we report in this paper an empirical analysis of the coupling between the street network and the subway for the two large metropolitan areas of London and New York. We observe a similar behaviour for network quantities related to quickest paths suggesting the existence of generic mechanisms operating beyond the local peculiarities of the specific cities studied. An analysis of the betweenness centrality distribution shows that the introduction of underground networks operate as a decentralizing force creating congestion in places located at the end of underground lines. Also, we find that increasing the speed of subways is not always beneficial and may lead to unwanted uneven spatial distributions of accessibility. In fact, for London—but not for New York—there is an optimal subway speed in terms of global congestion. These results show that it is crucial to consider the full, multimodal, multilayer network aspects of transportation systems in order to understand the behaviour of cities and to avoid possible negative side-effects of urban planning decisions.

    This article addresses an aspect of racial residential segregation that has been largely ignored in prior work: the issue of geographic scale. In some metropolitan areas, racial groups are segregated over large regions, with predominately white regions, predominately black regions, and so on, whereas in other areas, the separation of racial groups occurs over much shorter distances. Here we develop an approach—featuring the segregation profile and the corresponding macro/micro segregation ratio—that offers a scale-sensitive alternative to standard methodological practice for describing segregation. Using this approach, we measure and describe the geographic scale of racial segregation in the 40 largest U.S. metropolitan areas in 2000. We find considerable heterogeneity in the geographic scale of segregation patterns across both metropolitan areas and racial groups, a heterogeneity that is not evident using conventional “aspatial” segregation measures. Moreover, because the geographic scale of segregation is only modestly correlated with the level of segregation in our sample, we argue that geographic scale represents a distinct dimension of residential segregation. We conclude with a brief discussion of the implications of our findings for investigating the patterns, causes, and consequences of residential segregation at different geographic scales.

    1985-02-01

    Brazil's capital city, Rio de Janeiro, has been called Latin America's slum capital, and is slowly losing its political position to Brasilia and its cultural and economic leadership to Sao Paolo. Rio's metropolitan area includes 14 municipalities and had a population of 9.64 million in 1984, making it Latin America's 4th largest and the world's 14th largest metropolitan area. The 452-square mile central city contains 5.35 million people. Projections predict that Rio will be the world's 9th largest city in the year 2000, with a population of 13.3 million. Rio encompasses sharp social and economic contrasts; population density varies from 30,686 to 124 people per square mile and per capita municipal budgets range from $100 to $12.50. Like most metropolitan areas, Rio's suburbs show its greatest growth. The peripheral municipalities which held only 24% of the population in 1940, now have about 45%. Low land prices and government housing attact poor families to these areas which tend to be economically sluggish. Rio's fertility rate (2.8%) is the lowest in Brazil (4.2%) and life expectancy is somewhat higher than the national average. Low fertility and declining migration result in small households and increasing age structure. 2.2 million households, with 3.8 persons on an average, and 1.3 million households, with 3.6 persons, inhabited the metropolitan area and its municipality, respectively. Less of Rio's population are black (10%) or of mixed descent (39%) than in the rest of Brazil; the population is 97% Brazilian-born. Most metropolitan homes are owner occupied, but Rio also has many highly visible slums. Rio has an 84% literacy rate; 5% of the population have university degrees. The area's geography requires massive daily movement by nearly 60% of the population, and several municpalities function largely as commuter towns. Service jobs (especially for women) account for 27% of all jobs with manufacturing and tourism next in importance. Median monthly income

    Verma, R B; Basavarajappa, K G

    1989-09-01

    This paper examines the economic achievements of immigrant groups and compares them with those of the Canadian-born population. Employment income in this study is income for members of the labor force who worked 40 weeks or more, full time, during 1980. The information is from the 1981 Census. The 15 birthplace groups considered in this study are classified into 2 major groups: those from traditional sources and those from non-traditional or new sources. Traditional sources are the US, UK, and Europe. The new sources are Africa, Asia, South and Central America, the Caribbean, and Oceania. More than 1/2 of the immigrants from traditional sources arrived before 1960, whereas more than 1/2 of immigrants from new sources arrived after 1970. The analysis is only for those areas called Census Metropolitan Areas. Results of analysis show that 1) immigrant men and women in metropolitan areas earned 1.9% and 5.9% respectively less than their Canadian-born counterparts; 2) when differences in age and educational attainment were considered, incomes of immigrant men and women were about 7.5% below those of their Canadian-born counterparts; 3) the new immigrant groups earned far less than those of the Canadian-born counterparts; 4) traditional-source immigrants' incomes were equal to or slightly higher than Canadians'; and 5) as length of residence increases, most immigrant groups improve their relative economic position and achieve incomes comparable to Canadians'. The authors discuss the economic adaptation of immigrants in the light of various models: assimilation, Marxist class conflict, ethnic stratification and segmentation, structural pluralism, and structural change. No theory can be applied to the economic adaptation of all types of immigrants. Finally, refugees and sponsored relatives, who are not admitted on the basis of education and occupational need, are likely to have more difficulties than independent immigrants.

    This report introduces and discusses the present state of the helicopter emergency medical services (HEMS) in the metropolitan area of South Korea. The data of patients transported by HEMS from April 2007 to June 2009 were provided by Seoul Metropolitan Fire and Disaster Management Department. The data of patients subsequently transported to Korea University Guro Hospital were analyzed. During the study period, 725 emergency rescue calls were dispatched and 703 patients were rescued, of which 562 patients were judged by an emergency medical technician to be in a nonemergent condition and were referred to ground emergency medical services and 141 patients were judged as having an emergent situation and were directly transported to a nearby hospital. The data of patients who were transported to Korea University Guro Hospital by HEMS were as follows. The mean age was 51.7±12.1 years; 75.6% were male patients; 28 patients (68.3%) were traumatically injured; the mean of the injury severity score was 13.5±14.7, and 13 patients (46.4%) had an injury severity score of more than 15. No procedures other than basic life support were performed by the emergency medical technicians during transport. The role of HEMS in South Korea is limited to transporting injured patients from locations that cannot be approached by ground emergency medical services. Even though HEMS is essential considering the local mountainous geography of Seoul, Korea, overutilization of HEMS is still suspected in the metropolitan area.

    1997-12-31

    The introduction of several reformulated gasolines into the Mexico City Metropolitan Zone (MCMZ) in the middle 1986 is an example of using fuel composition to improve, in theory, the air quality. However, although these changes have resulted in an important reduction of lead airborne concentrations, a worsened situation has been created. Ozone levels in the atmosphere MCMZ have presented a sudden rise since the introduction of the first reformulated gasoline, reaching in the 1990`s an annual average of 1,700 exceedances to the Mexican Ozone Air Quality Standard (0.11 ppm not to be exceeded 1 hr. a day one day a year). The authors examine the tendency on ozone air quality in MCMZ in relation with the changes in gasoline composition since 1986. The authors also discuss the importance to perform an air quality impact analysis before the introduction of reformulated gasolines in countries where the local economy do not allow to change the old car fleet not fitted with exhaust treatment devices.

    2003-07-01

    This proposal outlines an action plan for risk management in the Delaware Valley Metropolitan Region. This plan is consistent with the goals for strengthening homeland security announced by President Bush, and is designed to complement efforts currently under development by Pennsylvania Emergency Management Agency and Department of Health. This plan proposes the formation of a Delaware Valley Risk Management Consortium, representing the critical disciplines and organizations related to risk assessment and management. This group would have membership from academic institutions, government agencies, industry, and nonprofit organizations. This Consortium would develop a systemic scope of work with the appropriate recommendations for technology acquisition, development and integration with risk management policies and procedures. This scope of work would include the development of two related information systems for the Delaware Valley Region. The first would be a comprehensive 'health monitoring' system to assess the continuity of operations, which would use integrated remote sensing and imaging, information gathering, communication, computation, and, information processing and management over wide-area networks covering the entire metropolitan area. The second would use real-time information from the health monitoring system to support interactive communication, search and information exchange needed to coordinate action among the relevant agencies to mitigate risk, respond to hazards and manage its resources efficiently and effectively.

    2013-05-01

    This research explored the link between coronary heart disease (CHD) prevalence and metropolitan-area level occupational structure among 137 metropolitan/micropolitan statistical areas (MMSA) in the United States. Using data from the 2006-2008 Behavioral Risk Factor Surveillance System and 2007 County Business Patterns, logistic mixed models were developed to estimate CHD prevalence between MMSAs controlling for individual-level socioeconomic characteristics and various types of occupational structure. Results showed that CHD prevalence was lower in MMSAs where their economy was dominated by 'tourism and resort' and 'the quaternary sector' and higher in MMSAs dominated by 'manufacturing', 'transportation and warehousing', and 'mining'. MMSA-level effects on CHD were found in 'tourism and resort' and 'the quaternary sector' having lower risk and 'mining' having higher risk of CHD. Although these effects prevailed in many MMSAs, some MMSAs did not fit into these effects. Additional analysis indicated a possible link between metropolitan population loss and higher CHD prevalence especially in the coal mining region of the Appalachian Mountains.

    1999-01-01

    Airport congestion at primary airports in major metropolitan areas was analyzed in a report prepared by the Transportation Research Board (TRB) in 1990. Taking the top twenty-three most congested airports from this study, a questionnaire was prepared and sent to the metropolitan planning organizations (MPOs) for twenty of the twenty-three metropolitan areas represented in the TRB study, The questionnaire focused on the role of the MPOs in planning for new primary airports in the United States, including questions about the status of the most recent MPO airport system plan, whether or not the latest plan recommends a new primary airport, and whether or not any other entities in the MPO areas are recommending new primary airports. The results indicated that 44.4 percent of the eighteen respondent MPOs have airport system plans that are five years old or older. Also, only two of the respondent MPOs have recommended a new primary airport in their latest regional airport system plan and only one of these two is a common recommendation in the Federal Aviation Administration's National Plan of Integrated Airport System.

    Dhaka Metropolitan City (including Dhaka and five adjacent municipal areas) is one of the fastest developing urban regions in the world. Densely build-up areas in the developed metropolitan area of Dhaka City are subject to extensive restructuring as common six- or lower storied buildings are replaced by higher and heavier constructions. Additional stories are built on existing houses, frequently exceeding the allowable bearing pressure on the subsoil as supported by the foundations. In turn, newly developing city areas are projected in marshy terrains modified by extensive, largely unengineered landfills. In most areas, these terrains bear unfavorable building ground conditions within 30 meters. Within a collaborative technical cooperation project between Bangladesh and Germany, BGR supports GSB in the provision of geo-information for the Capital Development Authority (RAJUK). For general urban planning, RAJUK successively develops a detailed area plan (DAP) at scale 1 : 50000 for the whole Dhaka Metropolitan City area (approx. 1700 km2). Geo-information have not been considered in the present DAP. Within the project, geospatial information in form of a geomorphic map, a digital terrain model and a 3-D subsurface model covering the whole city area have been generated at a scale of 1 : 50000. An extensive engineering geological data base consisting of more than 2200 borehole data with associated Standard Penetration Testing (SPT) and lab data has been compiled. With the field testing (SPT) and engineering geological lab data, the 3-D subsurface model can be parameterized to derive important spatial subsurface information for urban planning like bearing capacity evaluations for different foundation designs or soil liquefaction potential assessments for specific earthquake scenarios. In conjunction with inundation potential evaluations for different flooding scenarios, comprehensive building ground suitability information can be derived to support risk

    This work demonstrates that road traffic simulation of entire metropolitan areas is possible with reconfigurable supercomputing that combines 64-bit microprocessors and FPGAs in a high bandwidth, low latency interconnect. Previously, traffic simulation on FPGAs was limited to very short road segments or required a very large number of FPGAs. Our data streaming approach overcomes scaling issues associated with direct implementations and still allows for high-level parallelism by dividing the data sets between hardware and software across the reconfigurable supercomputer. Using one FPGA on the Cray XD1 supercomputer, we are able to achieve a 34.4 x speed up over the AMD microprocessor. System integration issues must be optimized to exploit this speedup in the overall simulation.

    1998-01-01

    OBJECTIVES: This study tested the hypothesis that the degree to which local government is metropolitanized is associated with mortality rates for African Americans and with residential segregation, which has itself previously been shown to be positively associated with mortality among African Americans. METHODS: One hundred fourteen US standard metropolitan statistical areas were examined. The primary dependent variable was the age-adjusted, race- and sex-specific all-cause mortality rate, averaged for 1990 and 1991. The 2 primary independent variables were residential segregation, as measured by the index of dissimilarity, and metropolitanization of government, as measured by the central city's elasticity score. RESULTS: Mortality rates for male and female African Americans were lower in metropolitan statistical areas with more metropolitanized local governments and lower levels of residential segregation. Mortality for male and female Whites was not associated in either direction with residential segregation. White male mortality showed no association with level of metropolitanization, but lower White female mortality rates were associated with less metropolitanization. CONCLUSIONS: This study suggests the need for further research into whether policy changes in areas not traditionally thought of as "health policy" areas can improve the health of urban minorities.

    Context This article explores the relationship between metropolitan fragmentation, as defined by the total number of governmental units within a metropolitan statistical area (local municipalities, special service districts, and school districts), and racial disparities in mortality among blacks and whites in the 1990s. The presence of numerous governmental jurisdictions in large metropolitan areas in the United States can shape the geography of opportunity, with adverse consequences for health. Methods We conducted a regression analysis using U.S. Census of Government data and Compressed Mortality File data for the country's largest 171 metropolitan statistical areas. Findings We found a link between increased metropolitan area fragmentation and greater racial differences in mortality between blacks and whites for both children and working-age adults. Although increasing fragmentation is associated with a higher mortality rate for blacks, it is not associated with a higher mortality rate for whites. These findings suggest that research is needed to understand how governance can positively or negatively influence a population's health and create conditions that generate or exacerbate health disparities. Conclusions We need to understand the extent to which metropolitan fragmentation contributes to racial segregation, whether racism contributes to both, and the role of poverty and antipoverty policies in reducing or exacerbating the consequences of metropolitan fragmentation. The exact pathways by which metropolitan fragmentation contributes to differences between blacks’ and whites’ mortality rates are unknown. Uncovering how institutions influence the social, economic, and environmental conditions, which in turn contribute to the current racial and ethnic health disparities in the largest metropolitan areas, is key. Understanding these “upstream” determinants of a population's health and the disparities in health between subgroups in the overall population

  14. Metropolitan migration and population growth in selected developing countries.

    PubMed

    1983-01-01

    The purpose of this article is to estimate the components of metropolitan population growth in selected developing countries during 1960-1970 period. The study examines population growth in 26 cities: 5 are in Africa, 8 in Asia, and 13 in Latin America, using data from national census publications. These cities in general are the political capitals of their countries, but some additional large cities were selected in Brazil, Mexico, and South Africa. All cities, at the beginning of the 1960-1970 decade had over 500,000 population; Accra, the only exception, reached this population level during the 1960s. Some cities had over 4 million residents in 1970. Net migration contributed about 37% to total metropolitan population growth; the remainder of the growth is attributable to natural increase. Migration has a much stronger impact on metropolitan growth than suggested by the above figure: 1) Several metropolitan areas, for various reasons, are unlikely to receive many migrants; without those cities, the share of metropolitan growth from net migration is 44%. 2) Estimates of the natural increase of migrants after their arrival in the metropolitan areas, when added to migration itself, changes the total contribution of migration to 49% in some metropolitan areas. 3) Even where net migration contributes a smaller proportion to metropolitan growth than natural increase, the rates of net migration are generally high and should be viewed in the context of rapid metropolitan population growth from natural increase alone. Finally, the paper also compares the components of metropolitan growth with the components of growth in the remaining urban areas. The results show that the metropolitan areas, in general, grow faster than the remaining urban areas, and that this more rapid growth is mostly due to a higher rate of net migration. Given the significance of migration for metropolitan growth, further investigations of the effects of these migration streams, particularly with

    This study describes a system for the automatic recording of positioning data for public transport vehicles used on roads. With the data provided by this system, transportation-regulatory authorities can control, verify and improve the routes that vehicles use, while also providing new data to improve the representation of the transportation network and providing new services in the context of intelligent metropolitan areas. The system is executed autonomously in the vehicles, by recording their massive positioning data and transferring them to remote data banks for subsequent processing. To illustrate the utility of the system, we present a case of application that consists of identifying the points at which vehicles stop systematically, which may be points of scheduled stops or points at which traffic signals or road topology force the vehicle to stop. This identification is performed using pattern recognition techniques. The system has been applied under real operating conditions, providing the results discussed in the present study.

    Background The purpose of this study is to evaluate the concentration of cardiovascular surgical procedures in a metropolitan area and investigate the perception of specialists regarding governmental policies to resolve this imbalance. Methods From March to May 2015, surveys were distributed to members of the Thoracic and Cardiovascular Surgery Association. The final pool of research subjects consisted of 75 respondents. Subjects were queried regarding the concentration of cardiovascular operations in metropolitan areas, alternatives to the imbalance, and governmental policies to resolve the inequalities. Results Survey participants responded that South Korea needs governmental policies to alleviate the concentration of cardiovascular surgery patients in large metropolitan hospitals. Participants agreed that the freedom to choose medical institutions and improved accessibility to metropolitan hospitals due to advanced transportation systems were some of the causes for the concentration. A majority (98.7%) of respondents thought establishing thoracic and cardiovascular surgery centers in provinces was an appropriate solution to alleviate the concentration. Thoracic and cardiovascular surgery specialists were ranked as the number one group on which to focus development. Conclusion Developing and carrying out policies to establish thoracic and cardiovascular surgery centers in provinces will alleviate the regional imbalance in available heart surgery services and an overall improvement in cardiovascular disease treatment in South Korea.

    TRANSIMS version 3.1 is an integrated set of analytical and simulation models and supporting databases. The system is designed to create a virtual metropolitan region with representation of each of the region’s individuals, their activities and the transportation infrastructure they use. TRANSIMS puts into practice a new, disaggregate approach to travel demand modeling using agent-based micro-simulation technology. TRANSIMS methodology creates a virtual metropolitan region with representation of the transportation infrastructure and the population, at the level of households and individual travelers. Trips a planned to satisfy the population’s activity pattems at the individual traveler level. TRANSIMS then simulates the movement of travelers and vehicles across the transportation network using multiple modes, including car, transit, bike and walk, on a second-by-second basis. Metropolitan planners must plan growth of their cities according to the stringent transportation system planning requirements of the Interniodal Surface Transportation Efficiency Act of 1991, the Clean Air Act Amendments of 1990 and other similar laws and regulations. These require each state and its metropotitan regions to work together to develop short and long term transportation improvement plans. The plans must (1) estimate the future transportation needs for travelers and goods movements, (2) evaluate ways to manage and reduce congestion, (3) examine the effectiveness of building new roads and transit systems, and (4) limit the environmental impact of the various strategies. The needed consistent and accurate transportation improvement plans require an analytical capability that properly accounts for travel demand, human behavior, traffic and transit operations, major investments, and environmental effects. Other existing planning tools use aggregated information and representative behavior to predict average response and average use of transportation facilities. They do not account

    McCurdy, Thomas; Zelenka, Michael P.; Lawrence, Philip M.; Houston, Robert M.; Burton, Robert

    This article presents data on ambient concentrations of selected acidic aerosols at four existing monitoring sites in the Pittsburgh PA metropolitan area. The data were collected by staff of the Allegheny County Health Department, Division of Air Quality during the summer and fall of 1993. The sampling protocol was focused on obtaining 24 h-average ammonia, ammonium, acidic sulfates, and particle strong acids data on a 2 to 3 day cycle. The data were obtained using Harvard University School of Public Health's "Short-HEADS" annular denuder sampling train. The Pittsburgh area is of interest because it is downwind of a major regional source of sulfur and nitrogen emissions from coal-burning power plants: the Ohio River Valley. The data presented here indicate that ground-level concentrations of acidic aerosols in Pittsburgh are highly correlated spatially and that many pollutants are higher on days when ground-level wind direction vectors indicate that wind is coming from the southwest rather than from the Pittsburgh source area itself. The monitoring site that is most upwind of the Pittsburgh source area - South Fayette - has particle strong acid levels about twice those of sites closer in to the Pittsburgh central business district.

    The combination between quantitative and qualitative research, "Homelessness among the Elderly in Bangkok Metropolitan" aimed to study causes of homelessness, patterns of living, problems, health status, social and health needs. Purposive sampling of 60 older homeless people could be divided into two groups; temporary and permanent homeless. Causes of homelessness were health problems, money problems, family background, emotional management, cultural sensitivities, limitation of extended family, financial management, political control, and domestic violence. Their living problems included:financial insecurity, police suppression, social and medical services, attacks from the young generations, sexual harassment, stealing, and social hierarchy of homelessness. 63.3% reported having hearing problems and a peptic ulcer before becoming homeless. These evolved into musculo-skeletal problems, accident-injuries, and skin diseases. 95% performed ADL/IADLs independently, 78.3% were depressed, 5% diagnosed with severe stress depression. 70% rated themselves happier than the rest ofthe population, and 75% were identified as having normal cognition. 58.3% had a good relationship with a religious network, 55% still had some contacts with theirfamily members. More than 90% indicated that they were satisfied, could sustainin a life on the street, were happy with theirfreedom, liked being close to green areas, learned about human life,fulfilled the dhamma, and felt close to the king.

  9. Increased tornado hazard in large metropolitan areas

    Cusack, Stephen

    2014-11-01

    The tornado climate was compared between large metropolitan areas and neighbouring non-metro cities using modern tornado reports in the Storm Prediction Center (SPC) archives. Twenty large metro areas in the higher-risk region of the U.S. were used to boost sample sizes hence robustness of results. Observational biases were minimised by using the most densely populated zips. The analysis found 50% greater tornado frequency and a thicker-tailed severity distribution in metro areas compared to the non-metro cities. These differences are significant at the 1% level. Regarding tornado frequency, the primary question is whether the raised occurrence rates in metro areas are due to observation biases or real differences in tornado climate. Past studies found no relative biases at the population densities used here, whereas there are two potential urban drivers of tornadogenesis. First, the urban heat island raises the storm severity above and downwind of main urban areas, as recorded in precipitation and lightning datasets. Second, the increased surface roughness over metro areas raises low-level shear which in turn has been found to be favourable for tornadogenesis. Modification of convective storms over large metro areas is the more plausible explanation of raised tornado frequency. The drivers of a thicker-tailed tornado severity distribution in metro areas are less certain. Potential causes include: increased debris-loading in metro tornadoes; modification of storms' lower boundary layer by increased surface roughness in metro areas; the reduced density of damage indicators in non-metro cities.

For most sites, the more difficult and costly aspect of increasing wide area network capacity is the local loop, which connects the facility LAN to the wide area service provider(s). Fermilab, in coordination with neighboring Argonne National Laboratory, has chosen to provide its own local loop access through leasing of dark fiber to nearby network exchange points, and procuring dense wave division multiplexing (DWDM) equipment to provide data channels across those fibers. Installing and managing such optical network infrastructure has broadened the Laboratory's network support responsibilities to include operating network equipment that is located off-site, and is technically much different than classic LAN network equipment. Effectively, the Laboratory has assumed the role of a local service provider. This paper will cover Fermilab's experiences with deploying and supporting a Metropolitan Area Network (MAN) infrastructure to satisfy its offsite networking needs. The benefits and drawbacks of providing and supporting such a service will be discussed.

    Understanding of the mechanisms driving our daily face-to-face encounters is still limited; the field lacks large-scale datasets describing both individual behaviors and their collective interactions. However, here, with the help of travel smart card data, we uncover such encounter mechanisms and structures by constructing a time-resolved in-vehicle social encounter network on public buses in a city (about 5 million residents). Using a population scale dataset, we find physical encounters display reproducible temporal patterns, indicating that repeated encounters are regular and identical. On an individual scale, we find that collective regularities dominate distinct encounters' bounded nature. An individual's encounter capability is rooted in his/her daily behavioral regularity, explaining the emergence of "familiar strangers" in daily life. Strikingly, we find individuals with repeated encounters are not grouped into small communities, but become strongly connected over time, resulting in a large, but imperceptible, small-world contact network or "structure of co-presence" across the whole metropolitan area. Revealing the encounter pattern and identifying this large-scale contact network are crucial to understanding the dynamics in patterns of social acquaintances, collective human behaviors, and--particularly--disclosing the impact of human behavior on various diffusion/spreading processes.

    The recent seismicity catalogue of metropolitan France Sismicité Instrumentale de l'Hexagone (SI-Hex) covers the period 1962-2009. It is the outcome of a multipartner project conducted between 2010 and 2013. In this catalogue, moment magnitudes (M w) are mainly determined from short-period velocimetric records, the same records as those used by the Laboratoire de Détection Géophysique (LDG) for issuing local magnitudes (M L) since 1962. Two distinct procedures are used, whether M L-LDG is larger or smaller than 4. For M L-LDG >4, M w is computed by fitting the coda-wave amplitude on the raw records. Station corrections and regional properties of coda-wave attenuation are taken into account in the computations. For M L-LDG ≤4, M w is converted from M L-LDG through linear regression rules. In the smallest magnitude range M L-LDG <3.1, special attention is paid to the non-unity slope of the relation between the local magnitudes and M w. All M w determined during the SI-Hex project is calibrated according to reference M w of recent events. As for some small events, no M L-LDG has been determined; local magnitudes issued by other French networks or LDG duration magnitude (M D) are first converted into M L-LDG before applying the conversion rules. This paper shows how the different sources of information and the different magnitude ranges are combined in order to determine an unbiased set of M w for the whole 38,027 events of the catalogue.

    There is concern over persons who fail to attend family planning clinics without reason. The represents 1 of the major stumbling blocks to a successful family planning program. The author investigated factors associated with clinic dropout among black women in a metropolitan area (Capetown, South Africa). Almost 1/2 of those who ceased to attend had a good reason for doing so. The main findings regarding the other defaulters included a lack of motivation among black women to prevent uplanned pregnancies through temporary contraception and that the program may not have met all of the public needs. In this regard, specific reference is made to the need of those women who no longer bring their youngest child to the child health clinic as family planning services are usually integrated into such a clinic.

    The authors report the results of an investigation into the possible association between air pollution and infant mortality from pneumonia in the Rio de Janeiro Metropolitan Area. This investigation employed multiple linear regression analysis (stepwise method) for infant mortality from pneumonia in 1980, including the study population's areas of residence, incomes, and pollution exposure as independent variables. With the income variable included in the regression, a statistically significant association was observed between the average annual level of particulates and infant mortality from pneumonia. While this finding should be accepted with caution, it does suggest a biological association between these variables. The authors' conclusion is that air quality indicators should be included in studies of acute respiratory infections in developing countries.

    To a great extent, research on geographic accessibility to mammography facilities has focused on urban-rural differences. Spatial accessibility within urban areas can nonetheless pose a challenge, especially for minorities and low-income urban residents who are more likely to depend on public transportation. To examine spatial and temporal accessibility to mammography facilities in the Atlanta metropolitan area by public and private transportation, we built a multimodal transportation network model including bus and rail routes, bus and rail stops, transfers, walk times, and wait times. Our analysis of travel times from the population-weighted centroids of the 282 census tracts in the 2-county area to the nearest facility found that the median public transportation time was almost 51 minutes. We further examined public transportation travel times by levels of household access to a private vehicle. Residents in tracts with the lowest household access to a private vehicle had the shortest travel times, suggesting that facilities were favorably located for women who have to use public transportation. However, census tracts with majority non-Hispanic black populations had the longest travel times for all levels of vehicle availability. Time to the nearest mammography facility would not pose a barrier to women who had access to a private vehicle. This study adds to the literature demonstrating differences in spatial accessibility to health services by race/ethnicity and socioeconomic characteristics. Ameliorating spatial inaccessibility represents an opportunity for intervention that operates at the population level.

  16. Metropolitan Influences on Migration into Poor and Nonpoor Neighborhoods*

    Data from the Panel Study of Income Dynamics and three decennial U.S. censuses are used to examine the influence of metropolitan-area characteristics on black and white households' propensity to move into poor versus nonpoor neighborhoods. We find that a nontrivial portion of the variance in the odds of moving to a poor rather to a nonpoor neighborhood exists between metropolitan areas. Net of established individual-level predictors of inter-neighborhood migration, black and white households are more likely to move to a poor or extremely poor tract rather than to a nonpoor tract in metropolitan areas containing many poor neighborhoods and a paucity of recently-built housing in nonpoor areas. Blacks are especially likely to move to a poor tract in metropolitan areas characterized by high levels of racial residential segregation and in which poor tracts have a sizeable concentration of blacks. White households are more likely to move to a poor than to a nonpoor tract in metropolitan areas that have comparatively few African Americans. PMID:21625368

    The safety of magnetically levitated (maglev) and high speed rail (HSR) trains proposed for application in the United States is the responsibility of the Federal Railroad Administration (FRA). Plans for near future US applications include maglev projects (e.g. in Orlando, FL and Pittsburgh, PA) and high speed rail (the French Train a Grande Vitesse (TGV) in the Texas Triangle). Concerns exist regarding the potential safety, environmental and health effects on the public and on transportation workers due to electrification along new or existing rail corridors, and to maglev and high speed rail operations. Therefore, the characterization of electric and magnetic fields (EMF) produced by both steady (dc) and alternating currents (ac) at power frequency (50 Hz in Europe and 60 Hz in the U.S.) and above, in the Extreme Low Frequency (ELF) range (3-3000 Hz) is of interest. A portable magnetic field monitoring system (augmented to include an electric fields probe) was used to sample, record and store 3 axis static and ac magnetic fields waveforms simultaneously, at multiple locations.

  18. Envisioning a metropolitan foodshed: potential environmental consequences of increasing food-crop production around Chicago

    Nationwide, cities are increasingly developing policies aimed at greater sustainability, particularly focusing on reducing environmental impact. Such policies commonly emphasize more efficiently using energy to decrease the greenhouse gas (GHG) footprint of the city. However, most plans ignore the food system as a factor in regional energy use and GHG emissions. Yet, the food system in the United States accounts for ~20% of per capita greenhouse gas emissions. Local, sustainable food production is cited as one strategy for mitigating GHG emissions of large metropolitan areas. “Sustainable” for regional agriculture is often identified as small-scale, diversified food crop production using best practices management. Localized food production (termed “foodshed”) using sustainable agriculture could mitigate climate change in multiple ways: (1) energy and therefore CO2-intensive portions of the conventional food system might be replaced by local, lower-input food production resulting in carbon offsets; (2) increased regional carbon storage might result from well-managed food crop production vs. commodity crop production; and (3) averted N2O emissions might result from closing nutrient cycles on agricultural lands following changes in management practices. The broader implications for environmental impact of widespread conversion to sustainable food crop agriculture, however, remain largely unknown. We examine the Chicago metropolitan region to quantify the impact of increased local food production on regional energy efficiency and GHG emissions. Geospatial analysis is used to quantify the resource potential for establishing a Chicago metropolitan foodshed. A regional foodshed is defined by minimizing cost through transportation mode (road, rail, or water) and maximizing the production potential of different soil types. Simple biogeochemical modeling is used to predict changes in N2O emissions and nutrient flows following changes in land management practices

    2013-07-01

    Low-income women with breast cancer who rely on public transportation may have difficulty in completing recommended radiation therapy due to inadequate access to radiation facilities. Using a geographic information system (GIS) and network analysis we quantified spatial accessibility to radiation treatment facilities in the Atlanta, Georgia metropolitan area. We built a transportation network model that included all bus and rail routes and stops, system transfers and walk and wait times experienced by public transportation system travelers. We also built a private transportation network to model travel times by automobile. We calculated travel times to radiation therapy facilities via public and private transportation from a population-weighted center of each census tract located within the study area. We broadly grouped the tracts by low, medium and high household access to a private vehicle and by race. Facility service areas were created using the network model to map the extent of areal coverage at specified travel times (30, 45 and 60 min) for both public and private modes of transportation. The median public transportation travel time to the nearest radiotherapy facility was 56 min vs. approximately 8 min by private vehicle. We found that majority black census tracts had longer public transportation travel times than white tracts across all categories of vehicle access and that 39% of women in the study area had longer than 1 h of public transportation travel time to the nearest facility. In addition, service area analyses identified locations where the travel time barriers are the greatest. Spatial inaccessibility, especially for women who must use public transportation, is one of the barriers they face in receiving optimal treatment.

  2. Groundwater contamination and risk assessment of industrial complex in Busan Metropolitan City, Korea

    -HCO3 or Na-HCO3 types. TDS (107-14,500 /L), EC (225-25,500 μS/cm), salinity (100-15,500 /kg), Na+ (13.39-2,866 /L) and Cl- (15.3-7,066 /L) concentrations are also higher than those of general groundwater. This fact indicates that groundwater in study area was polluted by saline water and/or anthropogenic sources. TCE, PCE, 1.1.1-trichloroethane (TCA) were analyzed by Busan Metropolitan City Institute of Health &Environment. PCE and TCA are not detected most of sites, while TCE is detected most of the sites and exceeds drinking water standard of Korea 0.03 /L. It is considered that TCE was derived from variety contamination sources such as car-washing centers, transportation companies, iron molding factories and waste treating companies. Risk assessment to human health and environmental resources by groundwater contamination was conducted. The RBCA Tool Kit for Chemical Releases can be used for the risk assessment at Tier 1 and Tier 2. The risk assessment determines risk-based concentration of constituents of concerns (COCs) that moves through groundwater, soil and air. It also evaluates carcinogenic risk and toxic effect when receptor exposures to the COCs. Tier 1 analysis determines risk-based screening levels (RBSLs) for one-site exposure. Tier 2 analysis evaluates RBSL and/or site-specific target levels (SSTLs) for both on-site and off-site receptor. RBSLs were calculated as 2.2E-2 /L for TCE and as 4.7E-3 /L for PCE at Tier 1 risk assessment. Average concentrations of TCE and PCE from measuring the groundwater samples were 0.15 mg/L and 0.016 mg/L, respectively. The actual measured values are higher than the RBSLs. Carcinogenic risk of TCE to animals was identified as B2 (inadequate or no human evidence but sufficient animal evidence). From this result, we will conduct the further detail risk assessment at Tier 2 level before conducting groundwater remediation.

    Uber and similar rideshare services are rapidly dispersing in cities across the United States and beyond. Given the convenience and low cost, Uber has been characterized as a potential countermeasure for reducing the estimated 121 million episodes of drunk driving and the 10,000 resulting traffic fatalities that occur annually in the United States. We exploited differences in the timing of the deployment of Uber in US metropolitan counties from 2005 to 2014 to test the association between the availability of Uber's rideshare services and total, drunk driving-related, and weekend- and holiday-specific traffic fatalities in the 100 most populated metropolitan areas in the United States using negative binomial and Poisson regression models. We found that the deployment of Uber services in a given metropolitan county had no association with the number of subsequent traffic fatalities, whether measured in aggregate or specific to drunk-driving fatalities or fatalities during weekends and holidays.

    "The study deals with size, main features (citizenship, sex and age) and legal status (settled and semi-settled legal migrants, illegal or irregular migrants) of [the] foreign population in six Italian metropolitan areas (Rome, Milan, Turin, Naples, Bologna and Palermo). Available data and their reliability are first analysed. The six metropolitan provinces reveal a very high concentration of foreign population, Rome and Milan in particular. The general picture is that of an increasing concentration of foreign residents in the capital city, but at the same time of the growing scattering in the metropolitan municipalities. Estimates for illegal or irregular migrants, obtained by applying the shares of illegality [emerging] from sample surveys to the regular stock, suggest that the percentage of illegal and irregular immigrants is particularly high in the provinces of Rome and Naples and is mainly connected with flows from Eastern Europe and North Africa."

    This research examines the larger-scale associations between obesity and food environments in metropolitan areas in the United States (US). The US Census County Business Patterns dataset for 2011 was used to construct various indices of food environments for selected metropolitan areas. The numbers of employees engaged in supermarkets, convenience stores, full service restaurants, fast food restaurants, and snack/coffee shops were standardised using the location quotients, and factor analysis was used to produce two uncorrelated factors measuring food environments. Data on obesity were obtained from the 2011 Behavioral Risk Factor Surveillance System. Individual level obesity measures were linked to the metropolitan area level food environment factors. Models were fitted using generalised estimating equations to control for metropolitan area level intra-correlation and individual level sociodemographic characteristics. It was found that adults residing in cities with a large share of supermarket and full-service restaurant workers were less likely to be obese, while adults residing in cities with a large share of convenience store and fast food restaurant workers were more likely to be obese. Supermarkets and full-service restaurant workers are concentrated in the Northeast and West of the US, where obesity prevalence is relatively lower, while convenience stores and fast-food restaurant workers are concentrated in the South and Midwest, where obesity prevalence is relatively higher. The food environment landscapes measured at the metropolitan area level explain the continental-scale patterns of obesity prevalence. The types of food that are readily available and widely served may translate into obesity disparities across metropolitan areas.

  12. Increasing spatiotemporal resolution of several major pollutant species in the Atlanta Metropolitan Area

    NASA Astrophysics Data System (ADS)

    Brosius, A. L.; Luong, K. Y.

    2014-12-01

    The American Lung Association cited Atlanta, Georgia, as one of the top 20 most polluted U.S. cities in 2014. Heavy air and ground transportation traffic contribute to the production of carbon dioxide (CO2), particulate matter (PM), and tropospheric ozone (O3) for the Atlanta Metropolitan Area (AMA). Hartsfield-Jackson Atlanta International Airport contributes significantly to the emission of these pollutants and their precursors. This study focuses on enhancing spatiotemporal resolution of CO2, PM, and O3in near-surface (ground to 50m) air columns by using Arduino-based sensors. The city of Decatur, due to its proximity to the airport, is the study site for the investigation of target pollutant concentrations. The results of this study, combined with other metropolitan air quality data sets, can be used to verify projected trends and append seasonal data. An understanding of the pollutant concentration distributions throughout the near-surface air column is vital to providing insight into the fluctuation of urban area pollutants.

  13. Three-dimensional behaviour of photochemical pollutants covering the Tokyo metropolitan area

    NASA Astrophysics Data System (ADS)

    Uno, Itsushi; Wakamatsu, Shinji; Suzuki, Makoto; Ogawa, Yasushi

    The spatial distribution and transport process of photochemical pollutants covering the Tokyo Metropolitan Area in Japan were investigated from 31 July to 2 August 1979. In the experiment, the vertical profiles of pollutants were observed using four instrumented aircraft. This paper mainly considers the transport process of the polluted air mass using three-dimensional trajectory analysis in which the wind field was determined by objective analysis techniques from pilot-balloon observation data. In the Tokyo Metropolitan Area the sea-land breeze circulation is an important factor in photochemical oxidant formation inland when the geostrophic wind is weak. The night-time radiation inversion which persists into the early morning prevents the dispersion of primary pollutants emitted from the big coastal industrial zones around Tokyo Bay. These pollutants are then advected by the land breeze to the Sagami Bay area which acts as storage tank. Conversion of such pollutants results in a high O 3 air mass inland with the penetration of the sea breeze. The sea breeze layer is thermally stable and inhibits vertical mixing of NO x. On the other hand, at the front of the sea breeze zone, a highly turbulent area transports the NO x to 1000-1500 m above mean sea level. Polluted air masses, with O 3 concentration exceeding 100 ppb, were observed at 500-1000 m on both 31 July and 1 August 1979. The maximum O 3 concentration on the 2nd day exceeded that on the 1st day. These high O 3 air masses contained aged pollutant and were entrained into the mixing layer as the depth of the mixing layer increased. This accelerated the formation rate of secondary pollutants. These early morning, high O 3 concentrations, and the storage capacity of the Sagami Bay area, are important factors in the time scale of air pollution phenomena in this region.

    Metropolitan Mexico City (MMC) is one of the most polluted urban areas in the world. The authors characterized the morphologic nasal mucosal changes in short-term (less than 30 days) and long-term (more than 60 days) exposures to the polluted southwest MMC atmosphere with high levels of ozone and other contaminants versus a control group of subjects living in a nonpolluted, low-ozone Mexican port. Seventy-six inferior turbinate biopsies were examined. The control group showed normal mucociliary epithelium, whereas the short-exposure group displayed loss of normal epithelium, basal cell hyperplasia, and mild dysplasia (17.64%). In the long-term exposure group, 78.72% of dysplasias were found (59.45% mild and 40.54% moderate) together with severe loss of normal respiratory epithelium, prominent basal cell hyperplasia, squamous metaplasia, and submucosal vascular proliferation. Our findings suggest that southwest metropolitan Mexico City inhabitants develop histopathologic changes in their nasal mucosa on exposure to the polluted city atmosphere.

  14. Occurrence and potential sources of pyrethroid insecticides in stream sediments from seven U.S. metropolitan areas

    USGS Publications Warehouse

    Kuivila, Kathryn; Hladik, Michelle; Ingersoll, Christopher G.; Kemble, Nile E.; Moran, Patrick W.; Calhoun, Daniel L.; Nowell, Lisa H.; Gilliom, Robert J.

    2012-01-01

    A nationally consistent approach was used to assess the occurrence and potential sources of pyrethroid insecticides in stream bed sediments from seven metropolitan areas across the United States. One or more pyrethroids were detected in almost half of the samples, with bifenthrin detected the most frequently (41%) and in each metropolitan area. Cyhalothrin, cypermethrin, permethrin, and resmethrin were detected much less frequently. Pyrethroid concentrations and Hyalella azteca mortality in 28-d tests were lower than in most urban stream studies. Log-transformed total pyrethroid toxic units (TUs) were significantly correlated with survival and bifenthrin was likely responsible for the majority of the observed toxicity. Sampling sites spanned a wide range of urbanization and log-transformed total pyrethroid concentrations were significantly correlated with urban land use. Dallas/Fort Worth had the highest pyrethroid detection frequency (89%), the greatest number of pyrethroids (4), and some of the highest concentrations. Salt Lake City had a similar percentage of detections but only bifenthrin was detected and at lower concentrations. The variation in pyrethroid concentrations among metropolitan areas suggests regional differences in pyrethroid use and transport processes. This study shows that pyrethroids commonly occur in urban stream sediments and may be contributing to sediment toxicity across the country.

  9. Implications of urban structure on carbon consumption in metropolitan areas

    NASA Astrophysics Data System (ADS)

    Heinonen, Jukka; Junnila, Seppo

    2011-01-01

    Urban structure influences directly or indirectly the majority of all green house gas (GHG) emissions in cities. The prevailing belief is that dense metropolitan areas produce less carbon emissions on a per capita basis than less dense surrounding rural areas. Consequently, density targets have a major role in low-carbon urban developments. However, based on the results of this study, the connection seems unclear or even nonexistent when comprehensive evaluation is made. In this letter, we propose a hybrid life cycle assessment (LCA) method for calculating the consumption-based carbon footprints in metropolitan areas, i.e. carbon consumption, with the emphasis on urban structures. The method is input-output-based hybrid LCA, which operates with the existing data from the region. The study is conducted by performing an analysis of the carbon consumption in two metropolitan areas in Finland, including 11 cities. Both areas consist of a dense city core and a less dense surrounding suburban area. The paper will illustrate that the influence of urban density on carbon emissions is insignificant in the selected metropolitan areas. In addition, the utilized consumption-based method links the climate effects of city-level development to the global production of emissions.

    PubMed

    Augustin, J; Austermann, J; Erasmi, S

    2016-10-18

    Background: One of the overall objectives of the legislator is to ensure an overall "homogeneous", and easily accessible medical care for the population. The physician-patient ratio can be used to describe the regional health care situation. But this method does not provide information concerning the availability of, for instance, the nearest doctor. Therefore, further parameters such as accessibility must be taken into consideration. For this purpose, network analyses are an appropriate method. The objective of this study is to present methodological tools to evaluate the healthcare situation in the metropolitan region of Hamburg, primarily focusing on accessibility using dermatologists as an example. Methods: Analyzing data of 20 counties, the geographical distribution of N=357 dermatologists and the physician-patient ratio were calculated. In a second step, a network analysis regarding accessibility was performed. In order to calculate accessibility, address data (physicians) were transformed into coordinates, consisting of defined places (N=303) and restrictions (e. g. speed, turn restrictions) of the network. The calculation of population-based accessibility is based on grid cells for the population density. Results: Despite adequacy of the overall medical situation, differences in the availability of the nearest dermatologists in the metropolitan region are remarkable, particularly when use of public transport is taken into consideration. In some counties, over 60% of the population require at least one hour to get to the nearest dermatologist using public transportation. In rural regions within the metropolitan area are particularly affected. Conclusion: The network analysis has shown that the choice and availability of transportation in combination with the location (rural/urban) is essential for health care access. Especially elderly people in rural areas with restricted mobility are at a disadvantage. Therefore, modern health care approaches (e

    The author has identified the following significant results. Work undertaken on a three-sensor land use data evaluation for a portion of the Phoenix area is reported. Analyses between land use data generated from 1970 high altitude photography and that detectable from ERTS and Skylab, especially in terms of changes in land use indicate that ERTS and Skylab imagery can be used effectively to detect and identify areas of post-1970 land use change, especially those documenting urban expansion at the rural-urban fringe. Significant preliminary findings on the utility of ERTS and Skylab data for metropolitan land use analysis, substantiated by evaluation with 1970 and 1972 ground control land use data are reported.

    2014-11-01

    Chang-Zhu-Tan Metropolitan Area experienced a typical multi-day pollution event in October 2013. Based on the air pollution index, conventional pollutants observations, surface meteorological observations and sounding data, the relationships of air pollution, large-scale circumfluence and boundary layer meteorology of this event were comprehensively analyzed. Additionally, the sources and transport paths of pollutions were investigated by application of satellite remote sensing data and HYSPLIT4 model. The results showed that pollutants gradually accumulated in the earlier stage of the event (October 21th to 26th) , while in the later stage (October 27th to 31th) the characteristic pollutants of crop residue burning (PM2.5, CO, NO2) sharply increased. The deterioration of air quality in the later stage was mainly related to the remote transport of pollutants caused by straw burning. Analysis of simulations of HYSPLIT4 model and fire spots showed that the currents mainly came from Anhui and Hubei Province in the earlier stage, while in the later stage they were mainly from Jiangxi Province where fire spots were intensively located. Stable atmospheric stratification caused by steady uniform high-pressure field and slight wind due to the confrontation of cold and warm currents greatly contributed to the development, maintainability and reinforcement of the pollution event. The remote transport of pollutants had a significant impact on ambient air quality of Chang-Zhu-Tan Metropolitan Area.

  2. Cooling energy savings potential of light-colored roofs for residential and commercial buildings in 11 US metropolitan areas

    1997-05-01

    Light-colored roofs reflect more sunlight than dark roofs, thus they keep buildings cooler and reduce air-conditioning demand. Typical roofs in the United States are dark, which creates a potential for savings energy and money by changing to reflective roofs. In this report, the authors make quantitative estimates of the impact of roof color by simulating prototypical buildings with light- and dark-colored roofs and calculating savings by taking the differences in annual cooling and heating energy use, and peak electricity demand. Monetary savings are calculated using local utility rates. Savings are estimated for 11 U.S. Metropolitan Statistical Areas (MSAs) in a variety of climates.

    Beneath the metropolitan Tokyo area, the Philippine Sea Plate (PSP) subducts and causes damaged mega- thrust earthquakes. The Dai-Dai-Toku Project revealed the geometry of the upper surface of PSP, and estimated a rupture process and a ground motion of the 1923 Kanto earthquake. However, these results are not sufficient for the assessment of the entire picture of the seismic hazards beneath the metropolitan Tokyo area including those due to an intra-slab M7+ earthquake. So, we have started a new project, the Special Project for Earthquake Disaster Mitigation in the Metropolitan Tokyo area. Proving the more detailed geometry and physical properties (e.g. velocities, densities, attenuation) of PSP is very important to attain this issue. The core item of this project is the dense seismic array observation in metropolitan area, which is called the MeSO-net (Metropolitan Seismic Observation network). The MeSO-net consists of 400 stations including those in Hakone, a Data Center at ERI (Earthquake Research Institute, the University of Tokyo), and a Sub-Center at NIED (National Research Institute for Earth Science and Disaster Prevention), at which the data are backuped and integrated with the Hi-net data. In order to obtain the high resolution images of a velocity and Q structure, it is requested to construct a seismic network with a spacing of 2-5 km. The total number of seismic stations of the MeSO-net will be about 400. The MeSO-net is to be deployed in 4 years and will provide useful datasets. Since the metropolitan area is surrounded with cultural noises, seismographs are installed at the bottom of the 20-m-deep borehole. Seismographs, data of which are digitized at the bottom of observation well, are three- component acceleration type with the maximum measurable acceleration of ±2G (dynamic range of 135 dB or more). The seismic data with a sampling rate of 200 Hz are telemetered to the Data Center using UDP/IP protocol. We adopt an autonomous cooperative seismic

    Aim The limited formal study of the clinical feasibility of implementing pharmacogenomic tests has thus far focused on providers at large medical centers in urban areas. Our research focuses on small metropolitan, rural and tribal practice settings. Materials & methods We interviewed 17 healthcare providers in western Montana regarding pharmacogenomic testing. Results Participants were optimistic about the potential of pharmacogenomic tests, but noted unique barriers in small and rural settings including cost, adherence, patient acceptability and testing timeframe. Participants in tribal settings identified heightened sensitivity to genetics and need for community leadership approval as additional considerations. Conclusion Implementation differences in small metropolitan, rural and tribal communities may affect pharmacogenomic test adoption and utilization, potentially impacting many patients. PMID:25712186

MASTER can be applied to any or all of the 268 Standard Metropolitan Statistical Areas (SMSAs) and 48 non-SMSA rest-of-state-areas (ROSAs) in the continental US. The model can also be applied to any or all of the continental US counties and states. This report is divided into four sections: capabilities and applications of the MASTER model, development of the model, model simulation, and validation testing.

    An understanding of epidemiological dynamics is important for prevention and control of epidemic outbreaks. However, previous studies tend to focus only on specific areas, indicating that application to another area or intervention strategy requires a similar time-consuming simulation. Here, we study the epidemic dynamics of the disease-spread over a commute network, using the Tokyo metropolitan area as an example, in an attempt to elucidate the general properties of epidemic spread over a commute network that could be used for a prediction in any metropolitan area. The model is formulated on the basis of a metapopulation network in which local populations are interconnected by actual commuter flows in the Tokyo metropolitan area and the spread of infection is simulated by an individual-based model. We find that the probability of a global epidemic as well as the final epidemic sizes in both global and local populations, the timing of the epidemic peak, and the time at which the epidemic reaches a local population are mainly determined by the joint distribution of the local population sizes connected by the commuter flows, but are insensitive to geographical or topological structure of the network. Moreover, there is a strong relation between the population size and the time that the epidemic reaches this local population and we are able to determine the reason for this relation as well as its dependence on the commute network structure and epidemic parameters. This study shows that the model based on the connection between the population size classes is sufficient to predict both global and local epidemic dynamics in metropolitan area. Moreover, the clear relation of the time taken by the epidemic to reach each local population can be used as a novel measure for intervention; this enables efficient intervention strategies in each local population prior to the actual arrival.

  16. Principal faults in the Houston, Texas, metropolitan area

    2005-01-01

    Summary -- This report, prepared by the U.S. Geological Survey in cooperation with the Harris-Galveston Coastal Subsidence District, documents and refines the locations of principal faults mapped in the Houston, Texas, metropolitan area in previous studies. Numerous subsurface faults have been documented beneath the Houston metropolitan area at depths of 3,200 to 13,000 feet. Some of these subsurface faults have affected shallower sediments, offset the present land surface (which has resulted in substantial, costly damage), and produced recognizable fault scarps. Evidence from previous studies indicates that these faults are natural geologic features with histories of movement spanning tens of thousands to millions of years. Present-day scarps reflect only the most recent displacements of faults that were active long before the present land surface of the area was formed. The precision of previously mapped fault locations was enhanced by overlaying mapped faults on a digital elevation model (DEM) of Harris County derived using light detection and ranging (Lidar). Lidar is a high-precision, laser-based system that enables collection of high-resolution topographic data. Previously mapped faults were adjusted to coincide with surface features that clearly indicate faults, which were made visible by the high-resolution topography depicted on the Lidar-derived DEM. Results of a previous study, supported by this study, indicate that faults in the southeastern part of the metropolitan area primarily occur in well-defined groups of high fault density. Faults in northern and western parts of the metropolitan area tend to occur either individually or in pairs with little tendency to cluster in high-density groups.

    2009-01-01

    Metropolitan bus drivers daily face work in a stressful and draining work environment, exposing them to the serious risk of driver fatigue. However, there has been a dearth of information exploring the unique antecedents and effects of such fatigue. To date, much of the research into metropolitan bus drivers has been under the umbrella of large heavy vehicle driving studies, which include a disproportionally large population of long-haul drivers, who are likely to face a significantly different set of fatigue factors [1]. The present study aimed to investigate which work and environmental factors may cause fatigue in metropolitan bus drivers by seeking drivers' own perspectives on the issues. To this end, focus groups were held at five bus depots in Sydney and Newcastle, with an effort made to include a stratified sample of drivers at each. Each of the groups were invited to nominate what factors they felt were most salient, with a number of common factors emerging across the depots. Key themes identified were: support from management; ticketing and related issues; interaction with passengers; cabin ergonomics; tight route schedules; turn-around and shift irregularity; extended shift cycles; interactions with other road users; and extended commute times.

    The importance of appropriate equipment to manage the difficult airway has been highlighted by the publication of the Australian and New Zealand College of Anaesthetists (ANZCA) guidelines in 2012. We set out to audit compliance with these guidelines in all public and private sites providing general anaesthesia in metropolitan Perth. Public and private health care websites identified 39 sites of which 37 were studied. Institutional and ethics approval was obtained. A tick-box design audit tool, based on the ANZCA guidelines, was used to collect information regarding the dedicated difficult airway container (DDAC) at each site. As recommended in the guidelines, only equipment within the DDAC was considered. Further data about each site, including the number of theatre suites, satellite anaesthetic areas, use of capnography and categories of patients treated (adult, obstetric and paediatric) were collected. An adult DDAC was found at 92% of all sites, but none of the sites had all the essential equipment listed in the ANZCA guidelines. There was limited provision of adult difficult airway equipment within private sites compared to public, and less provision of paediatric difficult airway equipment across all sites treating paediatric patients in metropolitan Perth. Capnography was available in 76% of post anaesthesia care units and used regularly in 27%. Adherence to the ANZCA guidelines regarding the DDAC could be improved. Standardised equipment across a metropolitan region would be of value in the management of the difficult airway.

    Intensive urbanization is swallowing municipal green areas which causes intensification of erosion, decrease in biodiversity and permanent fragmentation of habitats. In the face of these changes, a risk of irreversible damages to urban ecosystems is growing. That is why planning of solutions within the framework of Green Urbanism in metropolitan areas inhabited by over 55% of the global population is of extraordinary importance. The task of the paper is to present patterns of the Green Urbanism using selected examples of metropolitan areas as case studies. The main goal of the research is to make comparison between GU practices in different countries, in various spatial settings. The principles of triple zero framework: zero fossil-fuel energy use, zero waste, zero emissions (from low-to-no-carbon emissions) introduce not only the contemporary trends in theoretical urban planning but are dictated by practical considerations to create a healthy environment for a healthy society with a minimized environmental footprint. The research results help to identify Green Urbanism techniques used for multiple functions, including ecological, recreational, cultural, aesthetic and other uses and present opportunities for implementation of Green Urbanism solutions in metropolitan areas. To achieve healthier society and environment, highly congested and polluted cities have to be recreated through working with the existing landscape, topography and natural resources particular to the site.

    1997-01-01

    In this study, the author examined the spatial and temporal distribution of tetrachloroethylene, trichloroethylene, nitrate, and several other organic and inorganic chemicals in large community wells in the Fresno-Clovis Metropolitan Area and estimated the lifetime cancer risk associated with exposure to tetrachloroethylene and trichloroethylene. By 1992-1993, investigators found the industrial solvent tetrachloroethylene in 34 wells and found trichloroethylene in 16 wells. All wells had detectable levels of nitrate. In addition, investigators found radon, arsenic, cadmium, iron, manganese, trihalomethanes, and several other volatile organic chemicals in the wells, but only radon and arsenic posed a significant health risk. In 1995, 16 wells were closed because chemicals were found in them. Twenty-six of 248 (10.5%) active wells and 24 of 43 (55.8%) closed wells contained multiple contaminants, excluding nitrate. Between 1988 and 1993, concentrations of trichloroethylene, tetrachloroethylene, and nitrates increased in selected wells. Daily, monthly, and bimonthly variations in the concentrations of tetrachloroethylene, trichloroethylene, and nitrate were often considerable. Granulated activated carbon filtration reduced trichloroethylene levels in well water by 91%-95%, and the author examined its usefulness as a remedial measure. Estimated lifetime cancer risks for tetrachloroethylene and trichloroethylene were 1 excess cancer death per 9.5 million people and 1 excess death per 250 million, respectively. The author also included recommendations for the conduct of further epidemiological and environmental studies.

    Objectives Our aim was to identify the factors influencing the selection of a model of acute stroke service centralization to create fewer high-volume specialist units in two metropolitan areas of England (London and Greater Manchester). It considers the reasons why services were more fully centralized in London than in Greater Manchester. Methods In both areas, we analysed 316 documents and conducted 45 interviews with people leading transformation, service user organizations, providers and commissioners. Inductive and deductive analyses were used to compare the processes underpinning change in each area, with reference to propositions for achieving major system change taken from a realist review of the existing literature (the Best framework), which we critique and develop further. Results In London, system leadership was used to overcome resistance to centralization and align stakeholders to implement a centralized service model. In Greater Manchester, programme leaders relied on achieving change by consensus and, lacking decision-making authority over providers, accommodated rather than challenged resistance by implementing a less radical transformation of services. Conclusions A combination of system (top-down) and distributed (bottom-up) leadership is important in enabling change. System leadership provides the political authority required to coordinate stakeholders and to capitalize on clinical leadership by aligning it with transformation goals. Policy makers should examine how the structures of system authority, with performance management and financial levers, can be employed to coordinate transformation by aligning the disparate interests of providers and commissioners.

    Semipermeable membrane devices (SPMDs) were deployed in streams along a gradient of urban land-use intensity in and around six metropolitan areas: Atlanta, Georgia; Raleigh - Durham, North Carolina; and Denver - Fort Collins, Colorado, in 2003; and Dallas - Fort Worth, Texas; Milwaukee - Green Bay, Wisconsin; and Portland, Oregon, in 2004 to examine relations between percent urban land cover in watersheds and the occurrence, concentrations, and potential toxicity of hydrophobic compounds. Of the 142 endpoints measured in SPMD dialysates, 30 were significantly (alpha = 0.05) related to the percent of urban land cover in the watersheds in at least one metropolitan area. These 30 endpoints included the aggregated measures of the total number of compounds detected and relative toxicity (Microtox?? and P450RGS assays), in addition to the concentrations of 27 individual hydrophobic compounds. The number of compounds detected, P450RGS assay values, and the concentrations of pyrogenic polycyclic aromatic hydrocarbons (PAHs) were significantly related to percent urban land cover in all six metropolitan areas. Pentachloroanisole, the most frequently detected compound, was significantly related to urban land cover in all metropolitan areas except Dallas - Fort Worth. Petrogenic PAHs and dibenzofurans were positively related to percent urban land cover in Atlanta, Raleigh - Durham, Denver, and Milwaukee - Green Bay. Results for other endpoints were much more variable. The number of endpoints significantly related to urban land cover ranged from 6 in Portland to 21 Raleigh-Durham. Based on differences in the number and suite of endpoints related to urban intensity, these results provide evidence of differences in factors governing source strength, transport, and/or fate of hydrophobic compounds in the six metropolitan areas studied. The most consistent and significant results were that bioavailable, aryl hydrocarbon receptor agonists increase in streams as basins become

    The past devastating earthquakes in densely populated urban centers, such as the 1994 Northridge; 1995 Kobe; 1999 series of Kocaeli, Düzce, and Athens; and 2011 Van-Erciş events, showed that substantial social and economic losses can be expected. Previous studies indicate that inadequate emergency response can increase the number of casualties by a maximum factor of 10, which suggests the need for research on rapid earthquake shaking damage and loss estimation. The reduction in casualties in urban areas immediately following an earthquake can be improved if the location and severity of damages can be rapidly assessed by information from rapid response systems. In this context, a research project (TUBITAK-109M734) titled "Real-time Information of Earthquake Shaking, Damage, and Losses for Target Cities of Thessaloniki and Istanbul" was conducted during 2011-2014 to establish the rapid estimation of ground motion shaking and related earthquake damages and casualties for the target cities. In the present study, application to Istanbul metropolitan area is presented. In order to fulfill this objective, earthquake hazard and risk assessment methodology known as Earthquake Loss Estimation Routine, which was developed for the Euro-Mediterranean region within the Network of Research Infrastructures for European Seismology EC-FP6 project, was used. The current application to the Istanbul metropolitan area provides real-time ground motion information obtained by strong motion stations distributed throughout the densely populated areas of the city. According to this ground motion information, building damage estimation is computed by using grid-based building inventory, and the related loss is then estimated. Through this application, the rapidly estimated information enables public and private emergency management authorities to take action and allocate and prioritize resources to minimize the casualties in urban areas during immediate post-earthquake periods. Moreover, it

    Munich Re once ranked that Tokyo metropolitan region, the capital of Japan, is the most vulnerable area for earthquake disasters, followed by San Francisco Bay Area, US and Osaka, Japan. Seismologists also predict that Tokyo metropolitan region may have at least one near-field earthquake with a probability of 70% for the next 30 years. Given this prediction, Japanese Government took it seriously to conduct damage estimations and revealed that, as the worst case scenario, if a7.3 magnitude earthquake under heavy winds as shown in the fig. 1, it would kill a total of 11,000 people and a total of direct and indirect losses would amount to 112,000,000,000,000 yen(1,300,000,000,000, 1=85yen) . In addition to mortality and financial losses, a total of 25 million people would be severely impacted by this earthquake in four prefectures. If this earthquake occurs, 300,000 elevators will be stopped suddenly, and 12,500 persons would be confined in them for a long time. Seven million people will come to use over 20,000 public shelters spread over the impacted area. Over one millions temporary housing units should be built to accommodate 4.6 million people who lost their dwellings. 2.5 million people will relocate to outside of the damaged area. In short, an unprecedented scale of earthquake disaster is expected and we must prepare for it. Even though disaster mitigation is undoubtedly the best solution, it is more realistic that the expected earthquake would hit before we complete this business. In other words, we must take into account another solution to make the people and the assets in this region more resilient for the Tokyo metropolitan earthquake. This is the question we have been tackling with for the last four years. To increase societal resilience for Tokyo metropolitan earthquake, we adopted a holistic approach to integrate both emergency response and long-term recovery. There are three goals for long-term recovery, which consists of Physical recovery, Economic

  8. Modeling population exposure to community noise and air pollution in a large metropolitan area.

    Epidemiologic studies have shown that both air pollution and community noise are associated with cardiovascular disease mortality. Because road traffic is a major contributor to these environmental pollutants in metropolitan areas, it is plausible that the observed associations may be confounded by coexistent pollutants. As part of a large population-based cohort study to address this concern, we used a noise prediction model to assess annual average community noise levels from transportation sources in metropolitan Vancouver, Canada. The modeled annual average noise level was 64 (inter quartile range 60-68) dB(A) for the region. This model was evaluated by comparing modeled annual daytime A-weighted equivalent continuous noise levels (L(day)) with measured 5-min daytime A-weighted equivalent continuous noise levels (L(eq,day,5 min)) at 103 selected roadside sites in the study region. On average, L(day) was 6.2 (95% CI, 6.0-7.9) dB(A) higher than, but highly correlated (r=0.62; 95% CI, 0.48-0.72) with, L(eq,day,5 min). These results suggest that our model-based noise exposure assessment could approximately reflect actual noise exposure in the study region. Overall, modeled noise levels were not strongly correlated with land use regression estimates of traffic-related air pollutants including black carbon, particulate matter with aerodynamic diameter ≤2.5 μm (PM(2.5)), NO(2) and NO; the highest correlation was with black carbon (r=0.48), whereas the lowest correlation was with PM(2.5) (r=0.18). There was no consistent effect of traffic proximity on the correlations between community noise levels and traffic-related air pollutant concentrations. These results, consistent with previous studies, suggest that it is possible to assess potential adverse cardiovascular effects from long-term exposures to community noise and traffic-related air pollution in prospective epidemiologic studies.

  9. Advanced time and wavelength division multiplexing for metropolitan area optical data communication networks

    2005-09-01

    With the advent of new regulations governing the protection and recovery of sensitive business data, including the Sarbanes-Oxley Act, there has been a renewed interest in business continuity and disaster recovery applications for metropolitan area networks. Specifically, there has been a need for more efficient bandwidth utilization and lower cost per channel to facilitate mirroring of multi-terabit data bases. These applications have further blurred the boundary between metropolitan and wide area networks, with synchronous disaster recovery applications running up to 100 km and asynchronous solutions extending to 300 km or more. In this paper, we discuss recent enhancements in the Nortel Optical Metro 5200 Dense Wavelength Division Multiplexing (DWDM) platform, including features recently qualified for data communication applications such as Metro Mirror, Global Mirror, and Geographically Distributed Parallel Sysplex (GDPS). Using a 10 Gigabit/second (Gbit/s) backbone, this solution transports significantly more Fibre Channel protocol traffic with up to five times greater hardware density in the same physical package. This is also among the first platforms to utilize forward error correction (FEC) on the aggregate signals to improve bit error rate (BER) performance beyond industry standards. When combined with encapsulation into wide area network protocols, the use of FEC can compensate for impairments in BER across a service provider infrastructure without impacting application level performance. Design and implementation of these features will be discussed, including results from experimental test beds which validate these solutions for a number of applications. Future extensions of this environment will also be considered, including ways to provide configurable bandwidth on demand, mitigate Fibre Channel buffer credit management issues, and support for other GDPS protocols.

    In the Chicago six-county metropolitan area, the number of registered vehicles grew by over 800,000 vehicles in the 1980s; by contrast the population increased by just over 150,000 during the same time. This ratio of growth in automobiles versus population (five to one) has contributed to overall increases in travel, congestion and energy use. The objective of this report is to examine how and why this has occurred and what we might expect in the near future to address the growing traffic problems and energy use. Specifically, the focus is on energy use by household vehicles and other forms of passenger travel. Data on population trends, gasoline prices, commuting and transit use, and transportation energy use are presented and interpreted. Intelligent transportation systems and decreased single vehicle emissions are briefly described as methods to decrease congestion and pollution. 9 figs., 2 tabs.

    "The purpose of this paper is to analyze gross [U.S.] metropolitan migration of persons employed in selected...industries. An empirically testable model was developed for migration, employment change, and earnings change and implemented using data from the Social Security Administration's ten percent Continuous Work History Sample. The results showed that a significant percentage of the migration flows can be explained by the variables in the model.... Differences in cyclic and structural economic variables are noted in terms of their importance across the specified industries. The public policy implications of these results are identified."

  3. VNTR polymorphism in the Buenos Aires, Argentina, metropolitan population.

    VNTR loci provide a wealth of information for human genetic research, ranging from gene mapping to paternity testing and forensic identification. In this study we report the construction, validation, and analysis of the first local genetic database for VNTR markers for Argentina. A sample of the metropolitan population of Buenos Aires was typed by means of six VNTR systems. Allele frequencies and expected heterozygosity were calculated. The sample set was further tested for departures from Hardy-Weinberg equilibrium and power of exclusion. Allele frequency distributions are compatible with previously reported data on Caucasian populations, and no departures from Hardy-Weinberg equilibrium were detected.

    Title I of the Ryan White Comprehensive AIDS Resources Emergency (CARE) Act provides emergency assistance to eligible metropolitan areas (EMAs) to provide a continuum of care and services to people living with HIV disease. This article presents the results of a 2000-2001 survey of the 51 Title I Planning Councils. EMAs are serving significant numbers of females, with black and Hispanic persons constituting a majority of people served in 33 EMAs. Among the difficult to serve are substance abusers, people with chronic mental illness, multi-diagnosed people, the homeless, black males who have sex with males, and Hispanic persons. PMID:12500476

  5. Top Soils Geochemical and Radioactivity Survey of Naples (Italy) Metropolitan.

    NASA Astrophysics Data System (ADS)

    2001-05-01

    The metropolitan area of Naples due to intense human activities is an emblematic area affected by various environmental pollution of soils and waters in addition to hydrogeological volcanic, seismic and bradyseismic hazards. The geology of the area is prevailing represented by volcanics erupted, from the Upper Pleistocene to Recent by Mt. Somma-Vesuvius on the east and the Campi Flegrei fields on the west. The morphology of the metropolitan area of Naples city can be subdivided in flat areas, constituted by reworked pyroclastic terrains, and by hills originated by the overlapping of different welded pyroclastic flows (i.e.: Campanian Ignimbrite and Neapoletan Yellow Tuff) intercalated with pyroclastic deposits of different origins (i.e.: Campi Flegrei, Mt. Somma-Vesuvius, Ischia) and ages. In order to compile a multi-element baseline geochemical and radioactivity mapping of the metropolitan area of the Napoli we have sampled for this study, in situ top soil and imported filling material (mainly soil, volcanic ash, pumice and scoriae). The sampling and radioactivity survey has been carried out on about 200 sampling sites covering an area of about 150 Km2, with a grid of 0.5 x 0.5 km in the urbanised downtown and 1 km x 1 km in the sub urban areas. In each site has been determined a radioactivity by a Scintrex GRS-500 at different emission spectra as total radioactivity (> 0.08 MeV and > 0.40 MeV), 238U (at 1.76 MeV mostly from 214Bi), 232Th (at 2.6 MeV mostly from 208Tl) and 40K (at 1.46 MeV mostly for 40K). The range of values of in situ soils are as follow for the in situ soils (Total radioactivity: 1327- 360 and 114- 47; 238U: 2.6- 1.3; 40K: 8.1- 3.1; 232U: 0.5- 0.1). Analyses of major, metallic elements and pH of each soil sample are in progress, while Pb isotopes compositions, for a selected number of samples, will be determined to discriminate the natural (geogenic) from the anthropogenic components in the soils by versus the anthropogenetic origin.

    This paper focuses on the relationship between metropolitan and regional health planning based on the processes of regionalization and the Pact for Health in the Baixada Santista Metropolitan Area, São Paulo State, Brazil. The method used was a case study in two stages, namely during initial implementation of the Pact for Health (2007) and the Regional Administration Committees (CGR) and in 2010. Municipal and regional health systems managers and the director of the Metropolitan Agency were interviewed, and records were analyzed from ten years of meetings of the Regional Inter-Administration Committee and the Regional Development Council. Four issues emerged: financing and infrastructure; health services utilization; inefficiency of the Regional Health Administration's instruments and decision-making levels; and the relationship between different levels in the Administration. Metropolitan health management remained as an underlying issue, appearing only incidentally or tangentially to regional management. Despite some limitations, the CGR has been legitimized as a space for regional health management.

  7. Measurements of Criteria Pollutants in Suburban Locations in the Mexico City Metropolitan Area

    2004-12-01

    In the town of Santa Ana in the southern part of the Mexico City Metropolitan Area (MCMA) at an approximate height of 370 meters above the Valley of Mexico, a series of criteria pollutants (nitrogen dioxide, ozone, sulfur dioxide, and carbon monoxide) and meteorological parameters (wind speed and direction, temperature and relative humidity) were measured during the MCMA-2003 field campaign during April 2003. Santa Ana is considered a border site, agriculture being the predominant activity. The generated data in Santa Ana was compared with those from two representative atmospheric monitoring stations from the southeast zone (CENICA Supersite) and southwest (Revolucion Station) of Mexico City. The carbon monoxide and ozone concentrations measured in Santa Ana are atypical for a rural area. The sulfur dioxide and nitrogen dioxide concentrations are characteristic of the local activity. The average obtained during the measurement time for carbon monoxide was 0.86 ppm, the presence of the contaminant was within a 0.3 to 1.5 ppm range, 5 to 95 percentile, and does not follow the observed behavior of the monitoring stations that are located inside the urban area, although during the night (10 pm to 6 am) the carbon monoxide in Santa Ana was preset in levels from 0.4 to 1.5 ppm, 5 to 95 percentiles, average 0.92 ppm, above the reported concentrations at Revolucion Station, levels from 0.1 to 1.7 ppm, 5 to 95 percentiles; average 0.72 ppm. The presence of this contaminant can be attributed to transportation and accumulation phenomena. The ozone daytime behavior is similar to the one observed in the CENICA and Revolucion stations, but with a lower magnitude, the daily maximum generally occuring 2 or 3 hours after the urban stations. The one-hour average maximum values were 133 ppb in Santa Ana area and 188 ppb in the city. During the night the average concentrations were 37 ppb in Santa Ana and 17 ppb in the urban area. Nevertheless, the ozone average value in Santa Ana

    A modified Vicsek-Szalay model is introduced. From this, experiments are performed in order to simulate the spatial morphology of the largest metropolitan area of México: a set of clusters formed by the Valle de México metropolitan area (VMMA), Puebla metropolitan area (PMA) and Toluca metropolitan area (TMA). This case is presented in detail and here is called the Central México metropolitan area (CMMA). To verify the effectiveness of our approach we study two other cases; the set of clusters formed by the Monterrey zone (MZ, formed by the Monterrey metropolitan area and the Saltillo City metropolitan area) and the Chihuahua zone (ChZ, formed by the Chihuahua metropolitan area, Delicias City and Cuauthemoc City ), with acceptable results. Besides we compute three different fractal measures for all our areas of interest (AOI). In this paper, we focus on the global feature of these fractal measures in the description of urban geography and obtained local information which normally comes from inner city structures and small scale human decisions. Finally, we verified that the Zipf law is fulfilled by our simulated urban morphologies, so we know that our model follows it. As is normal for actual city size distributions, the CMMA case is presented in detail. We intend to pave the way in the understanding of population spatial distribution in a geographical space.
