  14. Day/night ANVIS/HUD-24 (day HUD) flight test and pilot evaluations

    Science.gov (United States)

    Yona, Zvi; Weiser, Ben; Hamburger, Oded

    2004-09-01

    The Day/Night ANVIS/HUD-24 gives pilots the ultimate head-out flight solution: 24-hour operational capability from a single integrated system. The basic integrated system combines the standard Night Vision Goggle (NVG) image with vital aircraft flight and navigation information, currently operational on over 4500 helicopters worldwide. Introducing the new Day HUD add-on module the same flight information is displayed for day use. The Day Head Up Display (HUD) is an add-on, complimentary to the basic night ANVIS/HUD system (AN/AVS-7). A lightweight optical module enhancing the day flight operation is designed to allow utility and reconnaissance helicopter day-mission operation by providing complete daytime head-out flight information. This add-on unit enhances flight safety, maximizes tactical survivability, and increases situational awareness during critical landing and takeoff phases. The Day HUD offers a unique 25° field-of-view, monocular, see-through flight information display. It mounts directly to the standard NVG mounting, incorporating a state of the art AMLCD flat panel display, high brightness solid-state backlight and compact optics resulting in a high contrast, high visibility display. The Day HUD test and evaluation program included extensive man-machine interface tests and numerous flight test aircraft in more than six separate countries. This paper will also address flight training, customer acceptance and expand on these findings and observations.

  6. Linkage of the current ALS-resistance status with field history information of multiple fields infested with blackgrass (Alopecurus myosuroides Huds. in southern Germany

    Directory of Open Access Journals (Sweden)

    Herrmann, Johannes

    2016-02-01

    Full Text Available The repetitive use of herbicides as major tool to control troublesome weeds in agriculture caused an increase in resistant weeds lately, especially when Integrated Weed Management principles were ignored. In a case study approach we sampled blackgrass (Alopecurus myosuroides Huds. in three distinctive locations for at least 3 years. Based on field infestation level, greenhouse biotests and laboratory analyses we grouped 23 fields as resistant (R, 28 fields as less sensitive (I and 39 fields as sensitive (S with regard to their ALS resistance status. Field history information was collected for 90 fields. Variables regarding the frequency of 1 summer crops, 2 winter cereals, 3 ploughing, 4 herbicide use, and 5 early versus late seeding were calculated. Fields with a higher frequency of summer crops, ploughing and later sowing dates in the crop rotation were less frequently grouped into R and I. No relationship was found between the number of modes of action used and the resistance status. Intensity of ALS-inhibitor use and use of grass herbicides played a role to distinguish resistant from sensitive fields. Our results suggest that cultural measures to bring the blackgrass population size to lower levels are more important than the selection by the herbicide.

  10. An Information System and Urban Art Signaling

    Directory of Open Access Journals (Sweden)

    Inês Marques

    2009-04-01

    Full Text Available The purpose of this paper is to present a proposal for a system of information and signage focused on urban public art. This project has been carried out as a part of Universitat de Barcelona’s Degree on Urban Design. The system was conceived as a whole in the continuity of city space, although D. Pedro IV square (Rossio, in Lisbon (Portugal has been chosen as the study area. The system provides a network of information articulated in three levels of approximation (virtual and physical to artwork in the public space: Bus and Underground orientation subsystems: These subsystems provide information in the communicative space of public transport (underground and buses, linked with existing information systems and supplementing them. These subsystems provide information at some distance from artwork, placed in resident’s and tourist’s approximation route towards the local site. The information system application is concretized by maps which inform and orientate throughout the space. Local identification subsystem: This subsystem provides information in situ. This system’s device consists on small informational plaques inserted in the pavement, which allow the immediate identification of the works of art. This subsystem performs essentially the function of identification. Virtual Subsystem: This subsystem is based on the development of a public art information website, linked with the other physical subsystems. In spite of not being developed in the present work, this site will show artistic and historical detailed information as well as maps, thematic tour routes, etc. These three levels of the urban art Information and Signage System can function in an autonomous way, in spite of their  complementarities and the existing linkage between them. They will provide integrated information routes which can be followed in various directions.

    Urban land utilization plays an important role in city development. We establish the "Urban Land Information System based on GIS" in order to inspect urban land structure and utilize a model automatically. A series of codes abstracted from urban land sustainable utilization significance are used as measures in land inspection. GIS tools combined with "Urban Land Information System" make visible codes calculations and statistical results possible. Useful mathematic methods are cited to analyze the degree urban land sustainable and optimize land structure. By scientific system analysis, relationships among modules and system structure are illustrated clearly. As a result this study has drawn out the "Urban Land Information System" model.

    Brinch, J. [Energetics, Inc., Columbia, MD (United States); Ternes, M. [Oak Ridge National Lab., TN (United States); Myers, M. [USDOE, Washington, DC (United States)

    1996-07-01

    A five-year initiative between the US Department of Energy (DOE) and the US Department of Housing and Urban Development (HUD) demonstrated the feasibility of improving the energy efficiency of publicly-assisted housing. Twenty-seven projects and activities undertaken during 1990--95 involved research and field demonstrations, institutional and administrative changes to HUD policies and procedures, innovative financing and leveraging of federal dollars with non-federal money, and education, training, and technical assistance. With most of the 27 projects and activities completed, the two departments have initiated a five-year deployment effort, the DOE-Energy Partnerships for Affordable Homes, to achieve energy and water savings in public and assisted housing on a large scale throughout the country. A Clearinghouse for Energy Efficiency in Public and Assisted Housing managed by the National Center for Appropriate Technology (NCAT), will offer hands-on energy assistance to housing providers to complement DOE`s assistance. This paper presents the findings of the DOE-HUD Initiative, with primary attention paid to those projects which successfully integrated energy efficiency into private and public single and multifamily housing. The paper includes examples of the publications, case-study reports, exhibits and videotapes developed during the course of the Initiative. Information on the new DOE Energy Partnerships and on the NCAT Clearinghouse is also presented. New Partnership projects with the Atlanta and Chicago Housing Authorities describe the technical assistance envisioned under the Partnership.

  10. Analyzing Drivers' Attitude towards HUD System Using a Stated Preference Survey

    Directory of Open Access Journals (Sweden)

    Hongwei Guo

    2014-02-01

    Full Text Available It is very important for drivers to obtain driving information easily and efficiently. There are many advanced devices used for driving safety assistance. Of these assistance devices, the head-up display (HUD system can promote the reduction of driver's reaction time and improve spatial awareness. The drivers' attitude towards and preference for HUD system are crucial to design the functional framework and interface of HUD system. This study explored the relationships between drivers' attitude and HUD presentation image designs using stated preference data from questionnaire survey. The questionnaire included drivers' attitude towards the use of HUD and the preference for the information display zone and information display elements of the HUD. Contrastive analysis was adopted to examine the variations in drivers' attitude and preference for age and driving skills. According to the results, the participants have varying attitudes to HUD system, but most participants show relatively unified preference for the information display zone and information display elements. The results can also be used to customize a HUD presentation image which is in accordance with the drivers' feelings and preferences.

  1. EXPERIMENTAL STUDY OF INFORMAL NORMS OF URBAN COLORISTICS

    Directory of Open Access Journals (Sweden)

    2017-02-01

    Full Text Available The objective of the study was informal social norms of urban culture. The paper contains the detailed description of the experimental situation and the main steps of the field research, focused on the observance of informal social norms in the sphere of urban coloristics. The experiment was conducted in three districts of Smolensk (Russia – Leninskiy, Zadneprovskiy and Promyshlennyy. Particular attention was paid to the analysis of the results of the field research, including evaluation of reaction of participants (residents of multi-storied houses, breakers of informal norms of urban coloristics (experimenters and casual experiment witnesses (neighbors and passersby. In addition, the accuracy of results “forecasting”, done before the beginning of the experiment, is analyzed. The research was conducted using the methodology of breaking experiment that is one of the most provocative ways of studying informal norms in sociology and social psychology. The experiment allowed to draw a number of important conclusions. It showed that urban coloristics is regulated by strict informal norms, that are not noticed by citizens until a violation occurs. The power of informal norms is significantly underestimated by citizens, and their break causes a negative reaction and protest. The most important contribution to the study of informal norms of urban culture was the comparison of the reaction degree by men and women, by the residents of different districts (central, residential or blue-collar neighborhoods, by different age groups.

  11. Urban informality as a signifier: Performing urban reordering in suburban Rio de Janeiro

    Science.gov (United States)

    Müller, Frank I

    2017-01-01

    Urban informality is typically ascribed to the urban poor in cities of the Global South. Drawing on Judith Butler’s concept of performativity and taking the case of Rio de Janeiro in the context of the 2016 Olympic Games, this article conceptualizes informality as a signifier and a procedural, relational category. Specifically, it shows how different class actors have employed the signifier informality (1) to legitimize the confinement of marginalized populations; (2) to justify the organized efforts of the upper middle class to protect their ‘self-enclosed’ gated communities; and (3) to warrant the formation of opposition and alliances between inhabitants, activists, and researchers on the edges of the urban order. This article offers new perspectives to better understand the relationship between informality and confinement by examining the active role that inhabitants of marginalized settlements assume in the Olympic City.

  13. Three-dimensional system integration for HUD placement on a new tactical airlift platform: design eye point vs. HUD eye box with accommodation and perceptual implications

    Science.gov (United States)

    Harbour, Steven D.; Hudson, Jeffery A.; Zehner, Gregory F.

    2012-06-01

    The retrofitting of a cockpit with a Head-Up-Display (HUD) raises potential accommodation and perceptual issues for pilots that must be addressed. For maximum optical efficiency, the goal is to be able to place every pilot's eye into the HUD Eye Motion Box (EMB) given a seat adjustment range. Initially, the Eye Reference Point (ERP) of the EMB should theoretically be located on the aircraft's original cockpit Design Eye Point (DEP), but human postures vary, and HUD systems may not be optimally placed. In reality, there is a distribution of pilot eyes around the DEP (which is dominant eye dependent); therefore, this must be accounted for in order to obtain appropriate visibility of all of the symbology based on photonic characteristics of the HUD. Pilot size and postural variation need to be taken into consideration when positioning the HUD system to ensure proper vision of all HUD symbology in addition to meeting the basic physical accommodation requirements of the cockpit. The innovative process and data collection methods for maximizing accommodation and pilot perception on a new "tactical airlift" platform are discussed as well as the related neurocognitive factors and the effects of information display design on cognitive phenomena.

  8. The process of urban regeneration in context of information society

    Directory of Open Access Journals (Sweden)

    Bazik Dragana

    2006-01-01

    Full Text Available This paper deals with the concept of innovation of the urban regeneration process in context of transformations which are generated by information-communication technologies. From one aspect, Serbia has an exceptional human potential presented in number of 13,000 graduates each year, or in share of 42% of population who speaks English, which is the largest among all Eastern and Central European countries. This forms a basis for formulation of strategies of information society development in Serbia as well as for economic adjustments based upon knowledge, and for tracing the way to future knowledge society, i.e. eEurope 2020. On the other hand, we are witnessing an intensive development of huge complexes of mega and hypermarkets as a present dominant way for our city spaces' regeneration. At the same time, experiences from some other locations point to the deterioration of cities' urban identity as a consequence of the global capital infiltration and of development within an urban tissue of a huge complex of multi-national companies. Aiming to overcome the mistakes portrayed by international experience, as well as potential oversights that may occur because of routine and mismatch between certain phases of the sustainable development process, this paper makes an emphasis on the importance of an integral evaluation of the information society development trends and the spatial aspects of urban regeneration. It is essential to adjust devastated urban spaces as artifacts of one technological era to the actual information era with indication of future digital knowledge era, i.e. to plan, design and develop *according to new technological requirements and possibilities for new working places and new quality of living.

  11. Outside scene obscuration by a millimeter-wave radar image presented on a HUD

    Science.gov (United States)

    Huntoon, Richard B.; Rand, Timothy W.; Lapis, Mary Beth

    1995-06-01

    We investigated whether a raster image on a Head-Up Display (HUD) might interfere with runway recognition during a low-visibility (CAT II and IIIa) approach. The primary reason for incorporating a HUD into the flight deck is to allow the pilot to observe instrument information while maintaining a view of the outside scene. The raster image could, however, obscure the outside scene, leaving the pilot unaware that the approach or runway lights are visible. In our HUD lab, twenty-one subjects were asked to observe a simulated outside scene through a HUD and indicate when they first saw runway approach lights. Each subject was presented 12 data runs with a simulated 35-GHz raster radar image and stroke symbology simultaneously presented on the HUD, and 12 data runs with only stroke symbology on the HUD. Each run was conducted under simulated fog conditions of either 700-ft Runway Visual Range (RVR) or 1200-ft RVR. We found that the presence of the radar image decreased the recognition range by 24 percent (z equals 5.71, p < 0.001). Subjective comments by the study participants show that the radar serves as a valuable aid in confirming flight path alignment with the runway under low-visibility conditions.

  12. A Comparative Metroscope Model for Urban Information Flows

    Science.gov (United States)

    Fink, J. H.; Shandas, V.; Beaudoin, F.

    2011-12-01

    One of the most promising ways to achieve global sustainability goals of climate stabilization, poverty reduction, and biodiversity preservation is to make the world's cities more efficient, equitable, and healthful. While each city must follow a unique and somewhat idiosyncratic path toward these linked goals based on its history, geography, demography, and politics, movement in this direction can accelerate if cities can learn from each other more effectively. Such learning requires the identification of common characteristics and methodologies. We have created a framework for organizing and applying urban information flows, which we refer to as "Metroscopes." Metroscopes, which are analogous to the large instruments that have advanced the physical and life sciences, integrate six elements: data collection and input; classification through the use of metrics; data storage and retrieval; analytics and modeling; decision support including visualization and scenario generation; and assessment of the effectiveness of policy choices. Standards for each of these elements can be agreed upon by relevant urban science and policy sub-communities, and then can evolve as technologies and practices advance. We are implementing and calibrating this approach using data and relationships from Portland (OR), Phoenix (AZ) and London (UK). Elements that are being integrated include the Global City Indicators Facility at University of Toronto, the J-Earth database system and Decision Theater from Arizona State University, urban mobility analyses performed by the SENSEable City Lab at MIT, and Portland's Ecodistrict approach for urban management. Individual Metroscopes can be compared directly from one city to another, or with larger assemblages of cities like those being classified by ICLEI's STAR program, the Clinton Climate Initiative's C40, and Siemens Green Cities Index. This large-scale integration of urban data sets and approaches and its systematic comparison are key steps

  13. Migration, business formation, and the informal economy in urban Mexico.

    Science.gov (United States)

    Sheehan, Connor M; Riosmena, Fernando

    2013-07-01

    Although the informal economy has grown rapidly in several developing nations, and migration and informality may be related to similar types of credit constraints and market failures, previous research has not systematically attempted to identify if migrant households are more likely to start informal and formal businesses alike and if this association varies across local contexts. We examine the relationship between prior US migration and the creation of both formal and informal businesses in urban Mexico using several criteria to indirectly assess sector location. We use data from 56 communities from the Mexican Migration Project to estimate multilevel survival and nonmultilevel competing risk models predicting the likelihood of informal, formal, and no business formation. The recent return migration of the household head is strongly associated with informal business creation, particularly in economically dynamic areas. On the other hand, migrants are only marginally more likely to start formal businesses in highly economically dynamic sending areas.

    Directory of Open Access Journals (Sweden)

    Alessandro Bove

    2013-06-01

    Full Text Available The relationship between new technologies and urban space has become, especially with the introduction of the concept of smart city, the key in the definition of management options in the city itself.The opportunities provided by the use of new technologies to manage the complexity of multiple aspects on the relationship between city and people can address strategies and innovation in order to improve the quality of life of the inhabitants. In smart cities different groups of people with different instances can be directly involved in the transformation process and the planners’ choices can be supported by information that once would have required costly research. This possibility is granted by the availability of great quantities of data that can be collected and analyzed. Direct information can be gathered by multiple sensors (accelerometer, a geomagnetic sensor, and proximity sensor, etc. that offer an immediate evaluation of a specific phenomenon. At the same time other aspects can be evaluated by information obtained in social networks: these can contribute to the definition of urban design as the result of a multi criteria analyses. The way to achieve these strategies is a process of interaction between spatial reality and perceived reality made available by passive forms of participation that can help planners in understanding territorial actors’ / territorial users’ needs and requirements.Through this approach, the design and decisions about urban space are not to be indifferent to the needs expressed by various categories of population.

    Urban environments differ in a large number of key attributes; these include infrastructure, morphology, demography, and economic and social variables, among others. These attributes determine many urban properties such as energy and water consumption, greenhouse gas emissions, air quality, public health, sustainability, and vulnerability and resilience to climate change. Characterization of urban environments by a single property such as population size does not sufficiently capture this complexity. In addressing this multivariate complexity one typically faces such problems as disparate and scattered data, challenges of big data management, spatial searching, insufficient computational capacity for data-driven analysis and modelling, and the lack of tools to quickly visualize the data and compare the analytical results across different cities and regions. We have begun the development of an Urban Information System (UrbIS) to address these issues, one that embraces the multivariate "big data" of urban areas and their environments across the United States utilizing the Big Data as a Service (BDaaS) concept. With technological roots in High-performance Computing (HPC), BDaaS is based on the idea of outsourcing computations to different computing paradigms, scalable to super-computers. UrbIS aims to incorporate federated metadata search, integrated modeling and analysis, and geovisualization into a single seamless workflow. The system includes web-based 2D/3D visualization with an iGlobe interface, fast cloud-based and server-side data processing and analysis, and a metadata search engine based on the Mercury data search system developed at Oak Ridge National Laboratory (ORNL). Results of analyses will be made available through web services. We are implementing UrbIS in ORNL's Compute and Data Environment for Science (CADES) and are leveraging ORNL experience in complex data and geospatial projects. The development of UrbIS is being guided by an investigation of

    Full Text Available Revitalizing slum-area has been recognized as one of the most complicated parts in urban resettlement program. With such a context we need a particular mode of communication to initiate and generate the project based on people's own aspiration. There are problem characteristics here, which are usually executed by Information Technology (IT. It is a potential to overcome the problem by using IT based on its ability to manage abundant information with various variables. At least there are three prospective opportunities in applying IT in this area. Firstly, it is the role of visualization, where computer can execute several visual features of the projects, which will be more representative than the previous ones. Secondly, it is the role of IT in generating the customization process to everyone involved in the projects. The last is the role of IT as executing tool for project's database management.

  14. Informing Urban Decision Making with an Array of Things

    Jacob, R. L.; Catlett, C.; Beckman, P. H.; Sankaran, R.

    2015-12-01

    Over the next several decades, the population of the world's cities is projected to nearly double, increasing by 2.6 billion people and requiring massive urban expansion globally. This massive growth in urban density and scale will compound ongoing city challenges related to climate change, energy, infrastructure, public health, and more. Cities are using data they already collect such as 311 calls, bus and train operations, street repair orders, census data and building permits to help understand the complex interactions between the human, built and natural systems within a city and inform their decision making. Helping to guide urban decision-making is The Array of Things (AoT): a new tool for measuring many aspects of the physical environment of urban areas at the city block scale with continuous, reliable, integrated data from a variety of sensors. An AoT node includes multiple sensors to measure basic meteorological quantities such as pressure, temperature and humidity as well as light and trace gases such as carbon monoxide, nitrogen dioxide, sulfur dioxide and ozone. The sensors operate 24/7 with ingest frequencies as high as 1Hz. The nodes are modular and allow new sensors to be added or swapped out. The hardware/software backbone of an AoT node is provided by the Waggle architecture. Each AoT node includes, via Waggle, compute power from a single board computer running Linux that allows data to be processed in-situ and, if needed, command and control of components of the node. Data is communicated in near real-time typically through WiFi, 3G or wired ethernet to a designated host and resilience is built-in to prevent data loss if communication is disrupted. The AoT includes a software stack with a programmable API and cloud-based infrastructure for performing data ingest and further analysis. The first full instance of AoT will comprise 500 nodes deployed in the City of Chicago, each with power, Internet, and a base set of sensing and embedded information

    2015-10-01

    Full Text Available Tropical cyclone is a rapidly rotating storm system characterized by a low pressure center, strong winds, and a spiral arrangements of thunderstorms that produce heavy rain. Tropical cyclones typically form over large bodies of relatively warm water. On 6th October 2014 Hud Hud originates from a low pressure system that formed under the influence of an upper air cyclonic circulation in the Andaman Sea. On 9th October 2014 the IMD department classified the Hud Hud as a very severe cyclonic storm on IMD scale and category 4 on Staffir-Simpson scale. The cyclone hit the coast of Visakhapatnam on 12th October 2014 at wind speed of 175 km/h which caused extensive damage to the city and the neighbouring districts. The damage caused by Cyclone Hud Hud not only changed the landscape of the port city, but also made it the first city in the country to be directly hit by a cyclone since 1891 as per the records of the IMD. The remote sensing technique used here is NDVI. NDVI will separate vegetation and non-vegetation part. The NDVI will be classified in ERDAS and calculated the area using ARCGIS. The satellite data of 4th October 2014 show s before the cyclone, 14th October 2014 shows after the cyclone and 7th December 2014 after two month of cyclone.

  17. Intelligent Information Dissemination Scheme for Urban Vehicular Ad Hoc Networks

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available In vehicular ad hoc networks (VANETs, a hotspot, such as a parking lot, is an information source and will receive inquiries from many vehicles for seeking any possible free parking space. According to the routing protocols in literature, each of the vehicles needs to flood its route discovery (RD packets to discover a route to the hotspot before sending inquiring packets to the parking lot. As a result, the VANET nearby an urban area or city center may incur the problem of broadcast storm due to so many flooding RD packets during rush hours. To avoid the broadcast storm problem, this paper presents a hotspot-enabled routing-tree based data forwarding method, called the intelligent information dissemination scheme (IID. Our method can let the hotspot automatically decide when to build the routing-tree for proactive information transmissions under the condition that the number of vehicle routing discoveries during a given period exceeds a certain threshold which is calculated through our developed analytical packet delivery model. The routing information will be dynamically maintained by vehicles located at each intersection near the hotspot if the maintaining cost is less than that of allowing vehicles to discover routes themselves. Simulation results show that this method can minimize routing delays for vehicles with lower packets delivery overheads.

    Rodríguez-Gaviria, E. M.; Botero-Fernandez, V.

    2015-12-01

    Flood risk management in small urban areas in Colombia has a great degree of uncertainty due to the low availability and quality of data, the non-existent personnel qualified in the collection and processing of data, and the insufficient information to evaluate the risk and vulnerability. It is because of this that two methods are developed: one for the generation of flood threat maps for different return periods combining historical, geomorphological, and hydrological hydraulic methods assisted by remote sensors and SIG through the use of data acquired through field campaigns, official hydrological networks, orthophotos, multitemporal topographic maps, and ASTER, STRM, and LiDAR images. And another method in which categorical variables are established, linking local physical, social, economical, environmental and political-institutional factors that are explored through different media such as reports, news, databases, transects, interviews, community workshops, and surveys conducted at homes. Such variables were included within an analysis of multiple correspondence to conduct a descriptive study of the exposure, susceptibility, and capacity conditions and to create a vulnerability index that was spatially plotted spatially on maps. The uncertainty is reduced in the measure in which local knowledge is used as a source of information acquisition, of validation of what already exists, and of calibration of the proposed methods. This research was applied to the urban centers of Caucasia (Antioquia) and Plato (Magdalena), which have been historically affected by slow flooding of the Magdalena and Cauca river, it being especially useful in the selection of best alternatives for risk management, planning for development, and land use management, with the possibility of replicating it to benefit other municipalities that experience the same reality.

  2. The politics of urban informality in Philadelphia's recovery house movement.

    Science.gov (United States)

    Fairbanks II, Robert P

    2011-01-01

    There are some 60,000 vacant properties in the city of Philadelphia, 30,000 of which are abandoned row houses. In the neighbourhood of Kensington, street-level entrepreneurs have reconfigured hundreds of former working-class row homes to produce the Philadelphia recovery house movement: an extra-legal poverty survival strategy for addicts and alcoholics located in the city's poorest and most heavily blighted zones. The purpose of this paper is to explore, ethnographically, the ways in which informal poverty survival mechanisms articulate with the restructuring of the contemporary welfare state and the broader political economy of Philadelphia. It is argued that recovery house networks accommodate an interrelated set of political rationalities animated not only by retrenchment and the churning of welfare bodies, but also by the agency of informal operators and the politics of self-help. Working as an alternative and partially vestigial boundary institution or buffer zone to formal regimes of governance, the recovery house movement reflects the ‘other story’ of the new urban politics in Philadelphia.

  3. Urban regeneration, retail development and the role of information and communication technologies

    Directory of Open Access Journals (Sweden)

    Eunseong Jeong

    2013-06-01

    Full Text Available New urban planning concepts are progressive rather than radical perspectives from zoning to smart growth in the United States. In this respect, urban regeneration comes from adapting positive aspects from previous planning applications. The paper argues that urban regeneration pursues restoration of affirmative urban functions through appreciation of old and new perspectives. Today, information and communication technology (ICT plays a significant role in urban planning, particularly for many small businesses that utilize ICT as a marketing tool. Urban retailing is one important element in urban regeneration due to its ability to create local employment. The paper empirically analyzes the features of local employment in San Francisco, Boston, and New York City to find evidence of urban regeneration through LQ and LQM.

    Full Text Available In this article, I shall deal with the concept of hudūth (origination as contextualized by Avicenna, which emerges in the context of relation between God and the world, while relating the coming into existence of the world with temporality. Avicenna discusses that there are two kinds of origination according to his classification of the celestial and sublunary world in ontology. Rational beings, celestial souls and bodies, heavenly motion and time depend on this motion are known as essential coming into existence (hudūth dhātī. These things are eternal from the point of view of temporality. There is no time difference between them and God who is the ultimate cause of them. The sublunary world consists of matter and bodies of generation and corruption. The various movements of these bodies and the time that depends on the movements are of the topic: temporal coming into existence (hudūth zamānī.

  7. µ-shapes: Delineating urban neighborhoods using volunteered geographic information

    Directory of Open Access Journals (Sweden)

    Matt Aadland

    2016-06-01

    Full Text Available Urban neighborhoods are a unique form of geography in that their boundaries rely on a social definition rather than a well-defined physical or administrative boundary. Currently, geographic gazetteers capture little more than then the centroid of a neighborhood, limiting potential applications of the data. In this paper, we present µ-shapes, an algorithm that employs fuzzy-set theory to model neighborhood boundaries suitable for populating gazetteers using volunteered geographic information (VGI. The algorithm is evaluated using a reference dataset and VGI from the Map Kibera Project. A confusion matrix comparison between the reference dataset and µ-shape's output demonstrated high sensitivity and accuracy. Analysis of variance indicated that the algorithm was able to distinguish between boundary and interior blocks. This suggests that, given the existing state of GIS technology, the µ-shapes algorithm can enable neighborhood-related queries that incorporate spatial uncertainty, e.g., find all restaurants within the core of a neighborhood.

  8. Urban form and planning in the information age: Lessons from literature

    Directory of Open Access Journals (Sweden)

    Maeng Da-Mi

    2008-01-01

    Full Text Available This paper focuses on the relationship between information and communication technologies (ICT and urban form, and on urban planning response to spatial and economic consequences of ICT. It starts with literature-based review of how urban environments in the United States change with technological advances and explanations of the relationship between ICT and urban form. The paper also includes a discussion of the manner in which ICT impact is handled by urban planning. The literature review points to insufficient attention to the dynamics between ICT and urban planning and increasing gap between physical and economic development implications of ICT. It is the role of urban planners to balance the consideration of the physical and economic aspects against the prospects and opportunities offered by ICT. .

    Science.gov (United States)

    García-Díaz, César; Moreno-Monroy, Ana I.

    2012-02-01

    We develop an agent-based computational model in which the urban informal sector acts as a buffer where rural migrants can earn some income while queuing for higher paying modern-sector jobs. In the model, the informal sector emerges as a result of rural-urban migration decisions of heterogeneous agents subject to social influence in the form of neighboring effects of varying strengths. Besides using a multinomial logit choice model that allows for agent idiosyncrasy, explicit agent heterogeneity is introduced in the form of socio-demographic characteristics preferred by modern-sector employers. We find that different combinations of the strength of social influence and the socio-economic composition of the workforce lead to very different urbanization and urban informal sector shares. In particular, moderate levels of social influence and a large proportion of rural inhabitants with preferred socio-demographic characteristics are conducive to a higher urbanization rate and a larger informal sector.

  10. Effects of the amount of feedback information on urban traffic with advanced traveler information system

    2017-09-01

    In a real traffic system, information feedback has already been proven to be a good way to alleviate traffic jams. However, due to the massive traffic information of real system, the procedure is often difficult in practice. In this paper, we study the effects of the amount of feedback information based on a cellular automaton model of urban traffic. What we found most interesting is that when providing the traffic information of a part of a road to travelers, the performance of the system will be better than that providing the road's full traffic information. From this basis, we can provide more effective routing strategy with less information. We demonstrate that only providing the traffic information of about first half road from upstream to downstream can maximize the traffic capacity of the system. We also give an explanation for these phenomena by studying the distribution pattern of vehicles and the detailed turning environment at the intersections. The effects of the traffic light period are also provided.

    Full Text Available Natal is a city with environment singularities. The urban legislation tried to preserve the features of the local landscape delimiting “Areas for Controlling Building High”, destined to protect the scenic value of some parts of the city. In 1979 was created a “NonÆdificandi” area to protect the scenery of Ponta Negra beach, one of the most famous view of the city. Since this time, the real state market, the building constructers and the land owners of this area have exerted constant pressure in sense to abolish or to modify this legal instrument.Nowadays, the public administration presented a new project which try to answer public and private interests.This paper is the result of an inclusion of the University in this polemic issue. Architecture and Urban Planning and Statistic students of two universities of the city (UFRN and UNP, helped the process collecting data and producing information. The proposed of the investigation was to know the users of this area and their opinion about the subject. It was done together with the Public agency, Secretaria Especial de Meio Ambiente e Urbanismo. At the end, the students presented their particular solutions for the problem, inside the disciplines of Landscaping and Urban Planning.

    2012-02-01

    The goal of this work is to study rural-urban migration in the early stages of industrialization. We use an agent-based model and take into account the existence of informal and formal workers on the urban sector and possible migration movements, dependent on the agents' social and private utilities. Our agents are place on vertices of a square lattice, such that each vertex has only one agent. Rural, urban informal and urban formal workers are represented by different states of a three-state Ising model. At every step, a fraction a of the agents may change sectors or migrate. The total utility of a given agent is then calculated and compared to a random utility, in order to check if this agent turns into an actual migrant or changes sector. The dynamics is carried out until an equilibrium state is reached and equilibrium variables are then calculated and compared to available data. We find that a generalized Harris-Todaro condition is satisfied [1] on these equilibrium regimes, i.e, the ratio between expected wages between any pair of sectors reach a constant value.

  16. Open data for informal settlements: Toward a user׳s guide for urban managers and planners

    Directory of Open Access Journals (Sweden)

    Arnab Chakraborty

    2015-12-01

    Full Text Available Informal settlements exist in a legally contested space and the quality of – and access to – information about them has been historically limited. The open data movement promises to address this gap by offering alternative sources for information and free or low cost analytical platforms. However, in order to use open data effectively, urban managers and planners need guidance to navigate these new data sources, software, and server platforms, as well as acquire the necessary skills. In this paper, we begin to address these issues by developing a framework that organizes the sprawling and rapidly evolving world of open urban data. Our framework includes three broad categories (1 inputs and resources, (2 activities and outputs, and (3 outcomes. We then identify and describe the key subcomponents under each, and list the prominent products and resources available to urban managers and planners. For example, under inputs and resources, we discuss open urban data sources such as Open Street Maps, cyberinfrastructure for web hosting, application deployment, and data processing, and open source software that can be used to analyze and visualize collected or derived data. We also identify the key resources available to planners for training and discuss the complementary opportunities presented by conventional datasets such as census and open urban data. Finally, using examples from ongoing activities in Mumbai, we show how open data resources can be useful for understanding urbanization and better integrating informal settlements into formal urban management and planning processes. We suggest that urban managers and planners working in informal settlements should take greater advantage of open data resources in order to both better address current challenges as well as for shaping a better future for the communities they serve.

    Victoria Rautenbach

    2015-11-01

    Full Text Available Three-dimensional (3D modelling and visualisation is one of the fastest growing application fields in geographic information science. 3D city models are being researched extensively for a variety of purposes and in various domains, including urban design, disaster management, education and computer gaming. These models typically depict urban business districts (downtown or suburban residential areas. Despite informal settlements being a prevailing feature of many cities in developing countries, 3D models of informal settlements are virtually non-existent. 3D models of informal settlements could be useful in various ways, e.g. to gather information about the current environment in the informal settlements, to design upgrades, to communicate these and to educate inhabitants about environmental challenges. In this article, we described the development of a 3D model of the Slovo Park informal settlement in the City of Johannesburg Metropolitan Municipality, South Africa. Instead of using time-consuming traditional manual methods, we followed the procedural modelling technique. Visualisation characteristics of 3D models of informal settlements were described and the importance of each characteristic in urban design activities for informal settlement upgrades was assessed. Next, the visualisation characteristics of the Slovo Park model were evaluated. The results of the evaluation showed that the 3D model produced by the procedural modelling technique is suitable for urban design activities in informal settlements. The visualisation characteristics and their assessment are also useful as guidelines for developing 3D models of informal settlements. In future, we plan to empirically test the use of such 3D models in urban design projects in informal settlements.

    The Institute of geological and Mineral Exploration of Greece (I.G.M.E.), in the frame of CSF 2000-2006 (Community Support Framework 2000-2006), has been implementing the pilot project titled "Collection, Codification and Documentation of geothematic information for urban and suburban areas in Greece - pilot applications". Geological, geochemical, geophysical, geotechnical, hydrogeological and other data concerning the urban and surrounding areas of Drama (North Greece), Nafplio & Sparti (Peloponnesus) and Thrakomakedones (Attica) is collected. Drillings, geological and geotectonic mapping (scale 1:5.000) and other "in situ" measurements and field works are taking place. The contours of the 1:5.000 topographic maps are digitized and a high detail DEM is created. The DEM and ground control points collected with GPS are used for the Orthorectification of very high-resolution satellite data. Then, the orthorectified satellite data is used for the land use classification and the urban area mapping. All initial and derived analogical and digital data is compiled and processed in specially designed geo-databases in GIS Environment. The final results will be presented in geothematic maps of different scales (1:5.000, 1:10.000 etc). Thematic maps (geological, geotechnical, geochemical, geophysical etc) and other digital data such as geodatabases, DEMs will be available to all, public or private sector, concerning geological environment in urban and suburban areas. All these data will constitute the essential base for land use planning and environmental protection in specific urban areas. Through this pilot project, new scientific approaches, methodologies and standards will be developed and improved in order to be applied to other future projects concerning capital centers of the country.

  6. Obtaining Traffic Information by Urban Air Quality Inspection

    CERN Document Server

    Ferrante, P; Nicolosi, S; Scaccianoce, G; Traverso, M; Rizzo, G

    2011-01-01

    The level of air quality in urban centres is affected by emission of several pollutants, mainly coming from the vehicles flowing in their road networks. This is a well known phenomenon that influences the quality of life of people. Despite the deep concern of researchers and technicians, we are far from a total understanding of this phenomenon. On the contrary, the availability of reliable forecasting models would constitute an important tool for administrators in order of assessing suitable actions concerning the transportation policies, public as well private. Referring to the situation of the running fleet and the measured pollutant concentrations concerning the Italian town of Palermo, a data-deduced traffic model is here derived, its truthfulness being justified by a fuzzyfication of the phenomenon. A first validation of the model is supplied by utilising the emissions characteristics and the pollutant concentrations referring to a two years period of time. This work could represent a first attempt in de...

  7. Municipal solid waste recycling and the significance of informal sector in urban China.

    Linzner, Roland; Salhofer, Stefan

    2014-09-01

    The informal sector is active in the collection, processing and trading of recyclable materials in urban China. Formal waste management organisations have established pilot schemes for source separation of recyclables, but this strategy is still in its infancy. The amounts of recyclables informally picked out of the municipal solid waste stream are unknown as informal waste workers do not record their activities. This article estimates the size and significance of the current informal recycling system with a focus on the collection of recyclables. A majority of the reviewed literature detects that official data is displaying mainly 'municipal solid waste collected and transported', whereas less information is available on 'real' waste generation rates at the source. Based on a literature review the variables, the 'number of informal waste workers involved in collection activities', the 'amounts collected daily per informal collector' and the 'number of working days' are used to estimate yearly recyclable amounts that are informally diverted from municipal solid waste. The results show an interval of approximately 0.56%-0.93% of the urban population or 3.3-5.6 million people involved in informal waste collection and recycling activities in urban China. This is the equivalent to estimated informal recycling rates of approximately 17-38 w/w% of the municipal solid waste generated. Despite some uncertainties in these assessments, it can be concluded that a significant share of recyclables is collected and processed by informal waste workers. © The Author(s) 2014.

    2008-10-01

    Considering the demand of urban and rural planning and the characteristics of spatial information technology (SIT), the study focuses on the application of SIT to support multi-scale urban planning. Three scales of urban and rural planning, such as city and town system planning, urban master planning, and detailed urban planning, were studied based on SIT. Firstly, tacking Great Beijing Region as an example, which includes Beijing, Tianjin, and northern of Hebei province, the city and town system planning was studied, supported by the theory of spatial interaction between cities and towns, and GIS spatial analysis. Then, for the urban master planning of Beijing, the RS and GIS were applied to do the spatial development analysis based on RS image data and GIS spatial analysis. Regarding to the conservation planning of Beijing's Inner city, the third scale is detailed urban planning. RS, GIS, and VR were integrated to determine the conservation region and digital conservation way as well. Finally, three conclusions were worked out.

  10. 'Mafias' in the Waterscape: Urban Informality and Everyday Public Authority in Bangalore

    Directory of Open Access Journals (Sweden)

    Malini Ranganathan

    2014-02-01

    Full Text Available This article investigates the phenomenon of Bangaloreʼs urban 'water mafias', operators who extract and deliver groundwater to scores of informal residential areas in Indian cities. The term 'mafia' here is treated as a semantic area of situated meanings and cultural interpretations that needs to be historicised and prised open in order to better understand how the urban waterscape is produced and inhabited. It situates the provenance and workings of mafias within wider debates on urban informality, state formation, and urban infrastructure and space. Rather than seeing mafias as filling a gap where government water supply has failed, as mainstream narratives suggest, the paper argues that mafias must be seen as formative of the post-colonial state. It further suggests that the specific form of public authority exercised by water mafias explains the production of informality in Bangaloreʼs waterscape. Based on ethnographic research in 2007-2009, the paper characterises the everyday authority wielded by mafias along three main registers: (i the ability of mafias to make and break discursive and material boundaries between the formal and informal, public and private, and state and society, (ii the varied nature of mafiasʼ political practices, ranging from exploitation to electoral lobbying to social protection to the provision of welfare, and iii mafiasʼ complicity in both water and land regimes in a neo-liberalised urban political economy.

  11. Evaluation of Research Project on Integrated Management and Services of Urban Development Records, Archives, and Information

    2005-01-01

    To evaluate the project "Research in integrated management and services of urban development records, archives, and information" in progress, this paper analyzes "why", "what", and "how" issues of relevant integration research about integrated management and services of urban development records, archives, and information based on a survey of literature at home and abroad. By a comparative study of current integration research status and features, the author gives a critical analysis of the strengths and weakness of the project and provides recommendations for future research.Cross disciplinary studies indicate that ideals of integration can add values to collaboration, innovation,and optimum in managing evidence, information, memory, and knowledge of built environment cross-culture, cross-discipline, cross-domain, and cross institution for enhancing competitiveness and productivity of business. Cross cultural studies indicate that integrated records, archives, and information management as a whole into capital construction project management process, organizational information resources management systems, and the construction of digital urban development archival repository through service-control, process-control, and product-control are fundamental to guarantee the characteristics and quality of records and records system to support evidence-based e-government,e-business, and the sustainability development of digital city. Present studies on integrated management and services of urban development records, archives, and information have limitations on too much emphasis on integration for collaboration and optimum but not enough studies on integration for innovation and broader use.

    Management of the urban environment and urban development require well organized data and information as a basis for decision making, planning and policy development. Such data and information needs to be up-to-date, reliable and complete, and moreover be available at the time of need. The latter is especially relevant in the case of disasters such as fires, flooding, earthquakes and volcanic eruptions. Current and future impacts of the on-going climate changes increase the need for geo-referenced data and information on environment, biodiversity and public health, in support of preparation, protection, mitigation and reconstruction. It is important that urban authorities devote more attention and resources to data and information management in order to be able to cope with the present and future challenges of ever growing cities with increasing impacts on their surroundings, and moreover to deal with the impacts of environment and biodiversity on the cities, their population and economies. SOD, Woerden has a long and successful track record of certified training and education in the field of data and information management for authorities, including urban government. The courses provided by SOD cover a wide range of subjects from metadata and digitizing, to enterprise content management and geo-information management. While focused on the Netherlands, SOD also has initiated similar training opportunities in Belgium and Surinam, and efforts are under way in other countries. P. Geerders Consultancy has considerable experience as a consultant and trainer in the field of methods and technologies for the provision of information in support of decision-making, planning and policy development related to integrated management and sustainable development of natural resources. Besides in various countries of Europe, he has worked in Latin America and the Caribbean region. Since several years, P. Geerders works as a freelance teacher with SOD.

    In this paper, we describe efforts to use remote sensing data within the purview of an information support system, to assess urban thermal landscape characteristics as a means for developing more robust models of the Urban Heat Island (UHI) effect. We also present a rationale on how we have successfully translated the results from the study of urban thermal heating and cooling regimes as identified from remote sensing data, to decision-makers, planners, government officials, and the public at large in several US cities to facilitate better understanding of how the UHI affects air quality. Additionally, through the assessment of the spatial distribution of urban thermal landscape characteristics using remote sensing data, it is possible to develop strategies to mitigate the UHI that hopefully will in turn, drive down ozone levels and improve overall urban air quality. Four US cities have been the foci for intensive analysis as part of our studies: Atlanta, GA, Baton Rouge, LA, Salt Lake City, UT, and Sacramento, CA. The remote sensing data for each of these cities has been used to generate a number of products for use by "stakeholder" working groups to convey information on what the effects are of the UHI and what measures can be taken to mitigate it. In turn, these data products are used to both educate and inform policy-makers, planners, and the general public about what kinds of UHI mitigation strategies are available.

  17. Developing Informality: The Production of Jakartaʼs Urban Waterscape

    Directory of Open Access Journals (Sweden)

    Michelle Kooy

    2014-02-01

    Full Text Available This paper argues the need for new conceptualisations of the relationship between water and development to better reflect the reality of cities in the Global South. Using a case study of Jakarta, Indonesia, it traces how the development narrative for urban water supply contributed to the understanding of informality as a binary opposite of the urban infrastructural ideal (undeveloped, temporary, transitional. The paper explores the implications of this framing as they emerged through the outcomes of the largest international development intervention in Jakartaʼs water supply in the 1990s, which culminated in the current private-sector concession contracts. The case illustrates how informality in Jakartaʼs water supply should be understood not as a failure of the state, technology, or development to achieve the urban infrastructural ideal, but rather as a particular mode of urbanisation that was reliant on, and productive of, a range of informal practices. Given the current heterogeneity in water supply strategies in many cities of the Global South, we need to accept the so-called informal as an enduringly dominant, rather than a remnant, mode of supply, and attend to ways in which the codification of informal practices reveal a more nuanced politics of access that reflect complex realities of southern urban waterscapes.

  18. Applications of geographic information system and expert system for urban runoff and water quality management

    It is very important to select appropriate methods of collecting, predicting, and analyzing information for the development of urban water resources and the prevention of disasters. Thus, in this study an accurate data generation method is developed using Geographic Information System (GIS) and Remote Sensing (RS). The methods of development and application of an expert system are suggested to solve more efficiently the problems of water resources and quality induced by the rapid urbanization. The time-varying data in a large region, the An-Yang Cheon watershed, were reasonably obtained by the application of the GIS using ARC/INFO and RS data. The ESPE (Expert System for Parameter Estimation), an expert system is developed using the CLIPS 6.0. The simulated results showed agreement with the measured data globally. These methods are expected to efficiently simulate the runoff and water quality in the rapidly varying urban area. (author). 10 refs., 4 tabs., 10 figs.

    The challenges of how to ensure sustainable urban development are currently one of the important agenda among governments around the world. The stakeholders require the latest and high volume of geographic information for the decision making process to efficiently respond to challenges, improve service delivery to citizens, and plan a successful future of the city. However, it is time-consuming and costly to get the available information and some of the information is not up-to-date. Recently, GeoWeb 2.0 technological advances have increased the number of volunteers from non-professional citizen to contribute to the collection, sharing, and distribution of geographic information. The information known as Volunteered Geographic Information (VGI) has generated another approach of spatial data sources that can give up-to-date, huge volume of data, and available geographic information in a low cost for various applications. With this in mind, this paper presents a review of literature based on the potential use of Volunteered Geographic Information (VGI) in measuring sustainability of urban development. The review highlighted that social, economic, and environment as three pertinent pillars relating to the use of VGI for measurement sustainable urban development.

    Paul, C. K.

    1975-01-01

    The Land Use Management Information System (LUMIS) consists of a methodology of compiling land use maps by means of air photo interpretation techniques, digitizing these and other maps into machine-readable form, and numerically overlaying these various maps in two computer software routines to provide land use and natural resource data files referenced to the individual census block. The two computer routines are the Polygon Intersection Overlay System (PIOS) and an interactive graphics APL program. A block referenced file of land use, natural resources, geology, elevation, slope, and fault-line items has been created and supplied to the Los Angeles Department of City Planning for the City's portion of the Santa Monica Mountains. In addition, the interactive system contains one hundred and seventy-three socio-economic data items created by merging the Third Count U.S. Census Bureau tapes and the Los Angeles County Secured Assessor File. This data can be graphically displayed for each and every block, block group, or tract for six test tracts in Woodland Hills, California. Other benefits of LUMIS are the knowledge of air photo availability, flight pattern coverage and frequencies, and private photogrammetry companies flying Southern California, as well as a formal Delphi study of relevant land use informational needs in the Santa Monicas.

    2013-09-01

    Urban safety-net clinics are considered prime targets for the adoption of health information technology innovations; however, little is known about their utilization in such safety-net settings. Current scholarship provides limited guidance on the implementation of health information technology into safety-net settings as it typically assumes that adopting institutions have sufficient basic resources. This study addresses this gap by exploring the unique challenges urban resource-poor safety-net clinics must consider when adopting and utilizing health information technology. In-depth interviews (N = 15) were used with key stakeholders (clinic chief executive officers, medical directors, nursing directors, chief financial officers, and information technology directors) from staff at four clinics to explore (a) nonhealth information technology-related clinic needs, (b) how health information technology may provide solutions, and (c) perceptions of and experiences with health information technology. Participants identified several challenges, some of which appear amenable to health information technology solutions. Also identified were requirements for effective utilization of health information technology including physical infrastructural improvements, funding for equipment/training, creation of user groups to share health information technology knowledge/experiences, and specially tailored electronic billing guidelines. We found that despite the potential benefit that can be derived from health information technologies, the unplanned and uninformed introduction of these tools into these settings might actually create more problems than are solved. From these data, we were able to identify a set of factors that should be considered when integrating health information technology into the existing workflows of low-resourced urban safety-net clinics in order to maximize their utilization and enhance the quality of health care in such settings.

    2016-07-01

    In recent years, the Internet has emerged as an alternative information source on mental health problems. Yet, the profile of the typical Internet help seeker is to be determined. Based on data from a household survey of 2558 Beijing residents, the study investigates online information searches and help seeking for mental health problems. Multinomial logistic regressions are estimated for respondents' access to the Internet, and mental-health-related information searches and help seeking on the Internet for the whole community sample and the most psychologically distressed subsample. The study identifies a digital divide in online help seeking for mental health issues based on age, migration and hukou status, and socio-economic factors. Youth and high socio-economic status are significant predictors of Internet access and use. Among the whole community sample, rural-to-urban migrants are less likely to have access to the Internet and search information or seek help online. Among the most psychologically distressed subsample, urban-to-urban migrants are significantly more likely to have access to the Internet and search information or seek help online. Given the shortage of mental health professionals in China, online information dissemination and guided self-help, if properly designed, could offer a means to reach large numbers of individuals in a cost-effective manner.

  14. Consensus-Based Cooperative Control Based on Pollution Sensing and Traffic Information for Urban Traffic Networks.

    2017-04-26

    Nowadays many studies are being conducted to develop solutions for improving the performance of urban traffic networks. One of the main challenges is the necessary cooperation among different entities such as vehicles or infrastructure systems and how to exploit the information available through networks of sensors deployed as infrastructures for smart cities. In this work an algorithm for cooperative control of urban subsystems is proposed to provide a solution for mobility problems in cities. The interconnected traffic lights controller (TLC) network adapts traffic lights cycles, based on traffic and air pollution sensory information, in order to improve the performance of urban traffic networks. The presence of air pollution in cities is not only caused by road traffic but there are other pollution sources that contribute to increase or decrease the pollution level. Due to the distributed and heterogeneous nature of the different components involved, a system of systems engineering approach is applied to design a consensus-based control algorithm. The designed control strategy contains a consensus-based component that uses the information shared in the network for reaching a consensus in the state of TLC network components. Discrete event systems specification is applied for modelling and simulation. The proposed solution is assessed by simulation studies with very promising results to deal with simultaneous responses to both pollution levels and traffic flows in urban traffic networks.

  15. The Scale of Informality: Community-Run Water Systems in Peri-Urban Cochabamba, Bolivia

    Directory of Open Access Journals (Sweden)

    Andrea J. Marston

    2014-02-01

    Full Text Available The production of the urban waterscape is an ongoing process. In this paper, I examine the strategies used by members of 'water committees' in peri-urban Cochabamba, Bolivia in their attempts to ensure the long-term integration of their community-run water systems into municipal water plans. My analysis underscores two points. First, the water committees and their advocates have engaged a range of scalar strategies in an effort to transform their water systems from informal to quasi-formal (and therefore more temporally stable structures. Second, I contend that the literature on politics of scale can potentially enrich theories of urban informality. Interpreting the political strategies of informal collectives through a scalar lens highlights the fact that 'inter-institutional' alliances are usually also – and importantly – multi-scalar. The literature on politics of scale, moreover, offers an important reminder about the role of history in urban waterscapes. Scales of governance are not politically neutral, and scalar interventions can engage historical legacies that are not necessarily compatible with contemporary aspirations.

  16. Communicating Climate Hazards Information in the Urban Community to the Public

    Science.gov (United States)

    McCalla, M. R.

    2004-12-01

    Climate simulations are predicting an overall warming of the atmosphere due to greenhouse gases. For example, CO2 allows sunlight to reach the earth and warm its surface, but it prevents a portion of this surface heat from escaping the atmosphere. This greenhouse effect can result in higher mean atmospheric temperatures near the Earth's surface. If these predictions are correct, changes in temperature can increase the power demand to cool urban building structures (homes, schools, offices, storage facilities, etc.). Similarly, the regional and seasonal temperature fluctuations due to climate oscillations (El Nino, for example) may also increase the power demand for heating and cooling. A warming climate (or cooling climate, for that matter) can also affect the available water for drinking, irrigation, and generating power, all of which impact the viability and sustainability of the urban community. Additionally, urban areas are expanding. Consequently, the distance between city and wildlands is decreasing. The wildland-urban interface often stresses biodiversity, forestation, and the urban area's ability to respond adequately to such climate-induced hazards as forest fires, flooding, and coastal erosion. Thus climate has an impact on humans and vice versa. How can scientists communicate the impact of climate on the urban community? What is the best way to communicate the information so that the public can (1) be informed and (2) make informed decisions? How well is the nexus between climate science and impacts on and benefits to decision makers understood? What is the best way to fully exploit that connection so that the public can develop intervention measures to support the urban community's response to climatic impacts? The Office of the Federal Coordinator for Meteorological Services and Supporting Research (OFCM) is an interdepartmental office established in response to Public Law 87-843 with the express purpose of ensuring the effective use of federal

  17. Informal urban settlements and cholera risk in Dar es Salaam, Tanzania.

    Directory of Open Access Journals (Sweden)

    Katherine Penrose

    Full Text Available BACKGROUND: As a result of poor economic opportunities and an increasing shortage of affordable housing, much of the spatial growth in many of the world's fastest-growing cities is a result of the expansion of informal settlements where residents live without security of tenure and with limited access to basic infrastructure. Although inadequate water and sanitation facilities, crowding and other poor living conditions can have a significant impact on the spread of infectious diseases, analyses relating these diseases to ongoing global urbanization, especially at the neighborhood and household level in informal settlements, have been infrequent. To begin to address this deficiency, we analyzed urban environmental data and the burden of cholera in Dar es Salaam, Tanzania. METHODOLOGY/PRINCIPAL FINDINGS: Cholera incidence was examined in relation to the percentage of a ward's residents who were informal, the percentage of a ward's informal residents without an improved water source, the percentage of a ward's informal residents without improved sanitation, distance to the nearest cholera treatment facility, population density, median asset index score in informal areas, and presence or absence of major roads. We found that cholera incidence was most closely associated with informal housing, population density, and the income level of informal residents. Using data available in this study, our model would suggest nearly a one percent increase in cholera incidence for every percentage point increase in informal residents, approximately a two percent increase in cholera incidence for every increase in population density of 1000 people per km(2 in Dar es Salaam in 2006, and close to a fifty percent decrease in cholera incidence in wards where informal residents had minimally improved income levels, as measured by ownership of a radio or CD player on average, in comparison to wards where informal residents did not own any items about which they were

    Full Text Available This article is a review of the PhD thesis undertaken by Joanna Vearey that explores local government responses to the urban health challenges of migration, informal settlements, and HIV in Johannesburg, South Africa. Urbanisation in South Africa is a result of natural urban growth and (to a lesser extent in-migration from within the country and across borders. This has led to the development of informal settlements within and on the periphery of urban areas. The highest HIV prevalence nationally is found within urban informal settlements. South African local government has a ‘developmental mandate’ that calls for government to work with citizens to develop sustainable interventions to address their social, economic, and material needs. Through a mixed-methods approach, four studies were undertaken within inner-city Johannesburg and a peripheral urban informal settlement. Two cross-sectional surveys – one at a household level and one with migrant antiretroviral clients – were supplemented with semi-structured interviews with multiple stakeholders involved with urban health and HIV in Johannesburg, and participatory photography and film projects undertaken with urban migrant communities. The findings show that local government requires support in developing and implementing appropriate intersectoral responses to address urban health. Existing urban health frameworks do not deal adequately with the complex health and development challenges identified; it is essential that urban public health practitioners and other development professionals in South Africa engage with the complexities of the urban environment. A revised, participatory approach to urban health – ‘concept mapping’ – is suggested which requires a recommitment to intersectoral action, ‘healthy urban governance’ and public health advocacy.

    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

    Little is known about the resources used by urban caregivers of children with asthma to obtain health information. The authors analyzed data for 304 families of children with persistent asthma to describe (1) sources of health information, (2) access and use of Internet resources, and (3) the association between the caregiver's health literacy (HL) and use of health information sources. Overall, 37% of caregivers had limited HL. Most families received health information from a health care professional (94%), written sources (51%), family/friends (42%), non-print media (34%), and the Internet (30%). Less than half of caregivers had access to the Internet at home, but 73% reported Internet use in the past year. Caregivers with adequate HL were more likely to obtain information from multiple sources and to use and have access to the Internet. The results suggest that HL is associated with where caregivers obtain health information from for their children and their use of the Internet.

    More effective environmental pollution control and management are needed due to the increasing environmental impacts from a range of human activities and the growing public demands for a better living environment. Urban air pollution is a serious environmental issue that poses adverse impacts on the health of people and the environment in most metropolitan areas. In this paper, we propose a geoinformatics augmented framework of environmental modelling and information sharing for supporting effective urban air pollution control and management. This framework is outlined in terms of its key components and processes including: 1) an integrated, adaptive network of sensors for environmental monitoring; 2) a set of distributed, interoperable databases for data management; 3) a set of intelligent, robust algorithms and models for environmental modelling; 4) a set of flexible, efficient user interfaces for data access and information sharing; and 5) a reliable, high capacity, high performance computing and communication infrastructure for integrating and supporting other framework components and processes.

    2015-05-01

    Climate change in Ethiopia is occurring against a backdrop of rapid population growth and urbanization, entrenched poverty and a heavy burden of disease, and there is little information on specific health risks with which to approach adaptation planning and strengthen adaptive capacity. Using detailed household surveys (400 households, 1660 individuals, 100% participation) and focus groups in two informal urban communities in the Southern city of Shashemene, we identified locally relevant hazards and found that climate change is likely to intensify existing problems associated with poverty. We also showed that despite their proximity (situated only 1 km apart) the two communities differ in key characteristics that may affect climate change vulnerability and require nuanced approaches to adaptation. Detailed, community-level research is therefore necessary, especially where other sources of data are lacking, to ensure that adaptation activities in the world’s poorest communities address relevant risks.

    Urban land provides a suitable location for various economic activities which affect the development of surrounding areas. With rapid industrialization and urbanization, the contradictions in land-use become more noticeable. Urban administrators and decision-makers seek modern methods and technology to provide information support for urban growth. Recently, with the fast development of high-resolution sensor technology, more relevant data can be obtained, which is an advantage in studying the sustainable development of urban land-use. However, these data are only information sources and are a mixture of "information" and "noise". Processing, analysis and information extraction from remote sensing data is necessary to provide useful information. This paper extracts urban land-use information from a high-resolution image by using the multi-feature information of the image objects, and adopts an object-oriented image analysis approach and multi-scale image segmentation technology. A classification and extraction model is set up based on the multi-features of the image objects, in order to contribute to information for reasonable planning and effective management. This new image analysis approach offers a satisfactory solution for extracting information quickly and efficiently.

  10. Informal Space in the Urban Waterscape: Disaggregation and Co-Production of Water Services

    Directory of Open Access Journals (Sweden)

    Rhodante Ahlers

    2014-02-01

    Full Text Available This special issue explores the realities of water provision in 'informal' urban spaces located in different parts of the world through eight empirical, case-based papers. The collection of articles shows that formality and informality are fluid concepts that say more about the authority to legitimate certain practices than describe the condition of that particular practice. In this introductory article we provide a historical overview that links the academic discussion on informality to urban water supply practices. Subsequently, we propose the concepts of disaggregation and co-production to describe how informality works, and how ideas about (informality are mobilised to label particular practices and service modalities. Disaggregation reveals that a single service delivery mechanism may incorporate activities, varying according to the degree to which they are formal or informal. Co-production describes a process where hybrid service provision modalities are produced as a result of the articulation of socio-political, economic, biophysical and infrastructural drivers. The article concludes by identifying a series of research directions that emerged as a result of producing this special issue.

    The urban ecosystem possesses dissipating structures that can absorb substances and energy from the external environment and export products and wastes to maintain order within the system.Given these circumstances,this paper analyzed the ability of the urban ecosystem in Guangzhou City to sustain development from the perspective of entropy.The research was carried out in three steps.First,an evaluation index system that considers the ability of the urban ecosystem for sustainable development was formed based on the structures and functions of the urban ecosystem and the change in the entropy of the urban socioeconomic ecosystem.Second,the sustainable development ability assessment model for the urban ecosystem was built using information entropy.Last,by combining the time series variation of the evaluation indicators with the entropy weights,this paper analyzed the influence of the combined factors on the sustainable development ability of the urban ecosystem in Guangzhou and suggested some measures to promote the sustainable development of the urban ecosystem in Guangzhou.The conclusions of this study can be summarized as follows:(1) The urban ecosystem has developed in an orderly and healthy direction,with effective control over the urban environmental pollution problems in Guangzhou between 2004 and 2010.(2) The sustainable development ability of the urban ecosystem had been on an upward trend in Guangzhou during the study period.The ability of the natural urban ecosystem to support the urban socioeconomic ecosystem increased continuously,and the improved ecoenvironment enhanced the harmony and vitality of the urban ecosystem in Guangzhou.

  12. Regulation of formal and informal water service providers in peri-urban areas of Maputo, Mozambique

    Science.gov (United States)

    Matsinhe, Nelson P.; Juízo, Dinis; Macheve, Berta; Santos, Clara dos

    Service delivery to large areas of peri-urban Maputo depends largely on alternative informal service providers. These providers are located within the limits of Maputo, in a water supply area that is formally leased to a private operator. Informal service providers therefore operate within the main regulatory body, but their activity is presently unregulated. This paper discusses activities of informal alternative providers in peri-urban areas of Maputo, Mozambique, and opportunities to expand the reach and influence of the main regulatory body to this segment of service providers. The study was commissioned to assist the main regulatory body to setup a strategy to improve the pro-poor focus of the existing regulatory environment and so improve access to potable water for the majority of the under-serviced urban poor. Results of field surveys conducted in selected areas of peri-urban Maputo are presented. The surveys focused on the quality of services, the legal status of independent providers and the organization of water supply services at neighbourhood level. The results indicate that household water resellers and small-scale independent provides are presently an important and indispensable source of access to water for the majority of unconnected residents in peri-urban Maputo and that they are reported to cater for as many as 21% of unconnected households of such neighbourhoods. In the near future, alternative providers will continue to have a dominant role in service delivery in peri-urban Maputo, therefore their legalization and decentralization of certain regulatory functions to the neighbourhood level is required. A neighbourhood based management model is proposed for that purpose. The model is based on a standpipe management model that is broadened to include alternative service providers. The model addresses issues such as water pricing, bidding and compliance strategies, channels for consumer’s representation and possibilities of creating

    2015-01-01

    The present study aimed at evaluating the performance of two different pixel-based classifiers [spectral angle mapper (SAM) and support vector machines (SVMs)] in discriminating different land-cover classes in a typical urban setting, focusing particularly on urban vegetation cover by utilizing hyperspectral (EO-1 Hyperion) data. As a case study, the city of Athens, Greece, was used. Validation of urban vegetation predictions was based on the error matrix statistics. Additionally, the final urban vegetation cover maps were compared at a municipality level against reference urban vegetation cover estimates derived from the digitization of very high-resolution imagery. To ensure consistency and comparability of the results, the same training and validation points dataset were used to compare the different classifiers. The results showed that SVMs outperformed SAM in terms of both classification and urban vegetation cover mapping with an overall accuracy of 86.53% and Kappa coefficient 0.823, whereas for SAM classification, the accuracy statistics obtained were 75.13% and 0.673, respectively. Our results confirmed the ability of both techniques, when combined with Hyperion imagery, to extract urban vegetation cover for the case of a densely populated city with complex urban features, such as Athens. Our findings offer significant information at the local scale as regards to the presence of open green spaces in the urban environment of Athens. Such information is vital for successful infrastructure development, urban landscape planning, and improvement of urban environment. More widely, this study also contributes significantly toward an objective assessment of Hyperion in detecting and mapping urban vegetation cover.

    The algorithm ICARE-HS (Inversion Code for urban Areas Reflectance Extraction using HyperSpectral imagery) is presented in this paper. ICARE-HS processes airborne hyperspectral images for atmospheric compensation taking into account the strong relief of urban areas. A digital surface model is used to provide the 3D information, which is key to simulating relief-related effects such as shadow casting, multiple reflections between objects and variable illumination depending on local solid angle of view of the sky. Some of these effects are modeled using ray tracing techniques. ICARE-HS is applied to airborne hyperspectral data of the city center of Toulouse, which are also processed by a standard atmospheric correction method for comparison.

    To understand the status and its influencing factors of health information literacy among urban and suburban residents in China, and to explore the method for improving the health information literacy. From March to May in 2013, residents aged 18-60 years in six provinces in China were investigated with Questionnaire of Health Literacy of Diabetes Mellitus of the Public in China about self-reported health information literacy. The results of the survey were standardized by the 6th national census data. Logistic regression analysis was used to explore influencing factors of health information literacy. A total of 4 416 residents were surveyed, and 4 282 (97.0%) valid questionnaires were collected. After weight adjustments, 30.1% of the residents aged 18-60 years had adequate health information literacy in China, and the 95%CI of the rate was 28.5% - 31.6%. Totally, 70.8% of the residents ever actively searched for health information, 43.7% of the residents could easily retrieve the health information, 49.1% of the residents could easily understand the health information, 41.8% of the residents could confidently differentiate the quality of the health information and 51.1% of the residents ever searched health information on the internet. The results of multi-logistic regression showed that the rural residents, the males, those with lower levels of education, those with poor health had a lower health information literacy. The most trusted health information source was from doctors, and the trust rate reached 97.0%, followed by family members, friends or colleagues. The residents trusted the interpersonal communication more than the mass media and the new media. The level of health information literacy of the residents was generally low in China. To improve the health information literacy, high-quality health information services should be delivered to the residents, and the health education on the internet provided by the medical professionals should also be explored.

    Full Text Available This article reflects the use of urban space by women in urban informal sectors in the city of Guwahati located in North East India. The population influx from across the borders in the aftermath of the partition has huge implications both on polity and on economy of the northeastern states in general and Assam in particular.  Importantly, the urban informal sectors have a sizeable share in terms of its significant contributions towards Gross Domestic Product (GDP as well as generation of employment opportunities largely. Using a feminist perspective, the research is an attempt to investigate the engagement of women in the informal sector in greater Guwahati. Research findings reveal that the occupations of the women workers are location-specific, that is, the manufacturing sectors (textiles, food preparation, printing and skilled service are mainly home/shop based production (fixed locations whereas the service sectors (leisure, caring, elementary construction, elementary sales and cleaning occupation operate at variable locations (construction sites, street pavements, marketplaces and other various locations. Further analysis shows that the informal sector is highly demand dependent and such demands are in the central business areas of the city, therefore informal sector services (skilled services and elementary services are found to be located in and around the central areas of Guwahati city. Women operators in the informal sector are attracted to the central business district because of the many advantages that it enjoys relative to other parts of a city. The paper concludes by calling on policy makers and physical planning agencies to evolve more pragmatic strategies for urban development matters in order that urban informal sector activities can be integrated into urban development plans. Finally, further research is called for on how urban planners could redesign the urban space with appropriate consideration of the informal sector

    The high rate of global urbanization has resulted in a rapid increase in informal settlements, which can be de ned as unplanned, unauthorized, and/or unstructured housing. Techniques for ef ciently mapping these settlement boundaries can bene t various decision making bodies. From a remote sensing perspective, informal settlements share unique spatial characteristics that distinguish them from other types of structures (e.g., industrial, commercial, and formal residential). These spatial characteristics are often captured in high spatial resolution satellite imagery. We analyzed the role of spatial, structural, and contextual features (e.g., GLCM, Histogram of Oriented Gradients, Line Support Regions, Lacunarity) for urban neighborhood mapping, and computed several low-level image features at multiple scales to characterize local neighborhoods. The decision parameters to classify formal-, informal-, and non-settlement classes were learned under Decision Trees and a supervised classi cation framework. Experiments were conducted on high-resolution satellite imagery from the CitySphere collection, and four different cities (i.e., Caracas, Kabul, Kandahar, and La Paz) with varying spatial characteristics were represented. Overall accuracy ranged from 85% in La Paz, Bolivia, to 92% in Kandahar, Afghanistan. While the disparities between formal and informal neighborhoods varied greatly, many of the image statistics tested proved robust.

    2016-05-01

    Full Text Available Rapid urbanization has caused many environmental problems, such as the heat island effect, intensifying air pollution, pollution from runoff, loss of wildlife habitat, etc. Accurate evaluations of these problems demand an accurate delineation of the spatial extent of the urban fringe. Conceptual and analytical ambiguity of the urban fringe and a general lack of consensus among researchers have made its measurement very difficult. This study reports a compound and reliable method to delineate the urban fringe area using a case study. Based on the 'fringe effect' theory in landscape ecology, the existing land cover information entropy model for defining the urban fringe is renewed by incorporating scale theory, cartography and urban geography theory. Results show that the urban fringe area of Guangzhou and Foshan metropolitan area covers an area of 2031 km2, and it occupies over 31% of the total study area. Result evaluation by industry structure data shows satisfactory correspondence with different land cover types. This paper reports the method and outcome of an attempt to provide an objective, repeatable and generally applicable method for mapping its spatial extent from remote sensing imageries, and could be beneficial to relevant urban studies and urban fringe management projects.

    The urban climate is changing rapidly. Therefore, climate change and its projected impacts on environmental conditions must be considered in assessing and comparing urban planning alternatives. In this paper, we present an integrated framework for urban climate adaptation tool (Urban-CAT) that will help cities to plan for, rather than react to, possible risks. Urban-CAT will be developed as a scenario planning tool that is locally relevant to existing urban decision-making processes.

    Geographic information systems(GIS)are a widely used tool in urban planning and management.More and more cities and deecision-makers require its attributes of promptness,precision and visualization.But the application of GIS in urban environmental management is still a new field and relevant researches are getting on tardily.As a subsystem of GIS,an urban environmental management geographic information system(UEMGIS0should be a complex multi-discipline and multi-objective tool to perform quantitative multi-dimension analysis and to transfer the results into an expression legible to an ordinary user.It should be a dynamic system of prompt functions based on upgradable databases,and be composed of many subsystems respectively specialized in items about water,air,waste and noise as well as relative standards and regulations.However, existing UEMGISs mostly rely on the basic GIS too much to design the actual requirements of applications and managements in themselves,and the unavailability of sufficient fundamental data has retarded their improvement.In the design of a UEMGIS,the standardization of data classification should be taken into consideration to make the data exchangeable and shareable among its subsystems and within every subsystemj,and the applicable error limits for input data should be defined in accordance with the user s required precision of data out.Data acquisition can be easy and quick if remote sensing,global positioning system(GPS)and other technologies are combined with GIS,Rapidly progressing information fechnologies have been giving a bright prospect for the melioration of UEMGIS that will have great potential and wide application in environmental conservation.

    In an effort to understand the extent of the inequalities in health information resources across Alberta, SEARCH Custom, HKN (Health Knowledge Network) and IRREN (Inter-Regional Research and Evaluation Network) conducted a survey in December 2007 to determine what library resources currently existed in Alberta's seven rural health regions and the two urban health regions. Although anecdotal evidence indicated that these gaps existed, the analysis was undertaken to provide empirical evidence of the exact nature of these gaps. The results, coupled with the published literature on the impact, effectiveness and value of information on clinical practice and administrative decisions in healthcare management, will be used to build momentum among relevant stakeholders to support a vision of equitably funded health information for all healthcare practitioners across the province of Alberta.

    Full Text Available The Heat Energy Assessment Technologies (HEAT project uses high-resolution airborne thermal imagery, Geographic Object-Based Image Analysis (GEOBIA, and a Geoweb environment to allow the residents of Calgary, Alberta, Canada to visualize the amount and location of waste heat leaving their houses, communities, and the city. To ensure the accuracy of these measures, the correct emissivity of roof materials needs to be known. However, roof material information is not readily available in the Canadian public domain. To overcome this challenge, a unique Volunteered Geographic Information (VGI application was developed using Google Street View that engages citizens to classify the roof materials of single dwelling residences in a simple and intuitive manner. Since data credibility, quality, and accuracy are major concerns when using VGI, a private Multiple Listing Services (MLS dataset was used for cross-verification. From May–November 2013, 1244 volunteers from 85 cities and 14 countries classified 1815 roofs in the study area. Results show (I a 72% match between the VGI and MLS data; and (II in the majority of cases, roofs with greater than, or equal to five contributions have the same material defined in both datasets. Additionally, this research meets new challenges to the GEOBIA community to incorporate existing GIS vector data within an object-based workflow and engages the public to provide volunteered information for urban objects from which new geo-intelligence is created in support of urban energy efficiency.

    Full Text Available Plastid trnL-trnF and nuclear ribosomal ITS sequences were obtained from selected wild-type individuals of Polygonum minus Huds. in Peninsular Malaysia. The 380 bp trnL-trnF sequences of the Polygonum minus accessions were identical. Therefore, the trnL-trnF failed to distinguish between the Polygonum minus accessions. However, the divergence of ITS sequences (650 bp among the Polygonum minus accessions was 1%, indicating that these accessions could be distinguished by the ITS sequences. A phylogenetic relationship based on the ITS sequences was inferred using neighbor-joining, maximum parsimony and Bayesian inference. All of the tree topologies indicated that Polygonum minus from Peninsular Malaysia is unique and different from the synonymous Persicaria minor (Huds. Opiz and Polygonum kawagoeanum Makino.

    Full Text Available Informal urban green-space (IGS such as vacant lots, brownfields and street or railway verges is receiving growing attention from urban scholars. Research has shown IGS can provide recreational space for residents and habitat for flora and fauna, yet we know little about the quantity, spatial distribution, vegetation structure or accessibility of IGS. We also lack a commonly accepted definition of IGS and a method that can be used for its rapid quantitative assessment. This paper advances a definition and typology of IGS that has potential for global application. Based on this definition, IGS land use percentage in central Brisbane, Australia and Sapporo, Japan was systematically surveyed in a 10×10 km grid containing 121 sampling sites of 2,500 m2 per city, drawing on data recorded in the field and aerial photography. Spatial distribution, vegetation structure and accessibility of IGS were also analyzed. We found approximately 6.3% of the surveyed urban area in Brisbane and 4.8% in Sapporo consisted of IGS, a non-significant difference. The street verge IGS type (80.4% of all IGS dominated in Brisbane, while lots (42.2% and gaps (19.2% were the two largest IGS types in Sapporo. IGS was widely distributed throughout both survey areas. Vegetation structure showed higher tree cover in Brisbane, but higher herb cover in Sapporo. In both cities over 80% of IGS was accessible or partly accessible. The amount of IGS we found suggests it could play a more important role than previously assumed for residents' recreation and nature experience as well as for fauna and flora, because it substantially increased the amount of potentially available greenspace in addition to parks and conservation greenspace. We argue that IGS has potential for recreation and conservation, but poses some challenges to urban planning. To address these challenges, we propose some directions for future research.

    The urban environment often deals with issues concerning the deterioration of the constructed space and the quality of the environmental factors, in general terms meaning an unsatisfactory quality of life. Taking into account the complexity of the urban environment and the strong human impact, this ambience can be considered the ideal place for a varied range of risks to appear, being favoured by the external interventions and the dynamics of the internal changes that occur in the urban system, often unexpectedly. In this context, historic centre areas are even more vulnerable because of the age of the buildings and their socio-cultural value. The present study focuses on the development of a rapid assessment system of urban risks, putting emphasis on earthquakes. The importance of the study is shown by the high vulnerability that defines urban settlements, which can be considered socio-ecological systems characterized by a maximum risk level. In general, cities are highly susceptible areas because of their compactness and elevated degree of land occupancy, the Bucharest municipality being no exception. The street and sewerage networks disorganized the natural system resulted from the evolution of the lake-river system in Superior Pleistocene-Holocene and the intense construction activity represents a pressure that hasn't been measured and that is in need for a methodological interdisciplinary approach. In particular, the specific of Bucharest is given by the seismic risk based on an explosive urban evolution and the advanced state of degradation of the buildings. In this context, the Lipscani sector from the historic centre of the capital city is a maximum seismic vulnerability area, this being the result of its location in the Dâmbovita River meadow, on the brow and 80 m terrace, but more precisely because of the degradation of the buildings that cumulated the effects of the repeated earthquakes. The historic centre of Bucharest has not only a cultural function

    The Environmental Information System for Planners (EISP) is a proof of concept web-based system designed to support decision making within the UK planning framework by making information on environmental issues more widely accessible. It incorporates relevant outputs from the Natural Environment Research Council (NERC) Urban Regeneration and the Environment (URGENT) research programme and from research directly commissioned by the Office of the Deputy Prime Minister (ODPM). It supports three principal planning functions carried out by local authorities: pre-planning enquiries, development control decisions and strategic planning. Eleven environmental science themes are incorporated: Air quality, Shallow undermining, Landslide susceptibility, Groundwater protection, Flood risk, Drainage, Land contamination, Proximity to landfill, Biodiversity, Natural and Man-made heritage. Decision flow diagrams represent detailed analysis of workflow in each theme, taking account of best practice, regulatory responsibilities and planning guidance. Industry-standard web technologies integrate the flows and provide access to the system via secure web pages. Underpinning the system is an environmental geographical information system (GIS) containing up-to-date data, information and models relevant to each theme. The modular system design allows new legislation and local priorities and datasets to be easily incorporated. Web technology delivers information and research data that have hitherto been difficult for the non-specialist to access and have therefore been under-exploited. The study has demonstrated a successful application of the principles of e-Governance in an area where informed decisions commonly require specialist information. The system, if rolled out nationally, offers potential economic benefits and efficiency savings for both planners and developers.

    Full Text Available Normal 0 false false false IN X-NONE X-NONE The urban waste management is still crucial issues in most regions in Indonesia. Urban waste is considered as a cultural issue because of its impact on various life factors , especially in big cities such as Jakarta, Semarang, Surabaya, Bandung, Palembang and Medan. Currently, the average productivity of the urban waste is 0.5 kg / capita / day. If this is multiplied by number of people in some cities in Java and Bali, the total waste will reach about 100,000 tons / day. This number will still increase by increasing population growth. Therefore, the urban waste management is very important for cities in Indonesia, alhough currently not many cities applied the urban waste management system. Urban waste management in Indonesia is not merely caused by formal sector, but it is also supported by informal sector in reducing daily production waste up to 30%. The informal sector management is mainly conducted by sorting the waste to recycleable or not. The recycleable waste is then sold back to the mills to be converted to other valuable products. This reserach was aimed to evaluate the partnership between formal and informal sector in reduction of waste production in Semarang city through urban waste management system. The research about informal sector was conducted by communal interaction and qualitative analysis focusing at Semarang City especially at Old Town area. The research has provided substantive knowledge of informal sector partnerships and formal sector in urban waste management with case inorganic waste management in the city of Semarang through 3R (recycle, reuse and reduce knwoledge management. Basic knowledge of the structure / surface is characterized by empirical knowledge which was easily caught by the direct perspective of human. Middle knowledge could be adjusted to different loci

  15. Urban Built-Up Area Extraction from Landsat TM/ETM+ Images Using Spectral Information and Multivariate Texture

    2014-08-01

    Full Text Available Urban built-up area information is required by various applications. However, urban built-up area extraction using moderate resolution satellite data, such as Landsat series data, is still a challenging task due to significant intra-urban heterogeneity and spectral confusion with other land cover types. In this paper, a new method that combines spectral information and multivariate texture is proposed. The multivariate textures are separately extracted from multispectral data using a multivariate variogram with different distance measures, i.e., Euclidean, Mahalanobis and spectral angle distances. The multivariate textures and the spectral bands are then combined for urban built-up area extraction. Because the urban built-up area is the only target class, a one-class classifier, one-class support vector machine, is used. For comparison, the classical gray-level co-occurrence matrix (GLCM is also used to extract image texture. The proposed method was evaluated using bi-temporal Landsat TM/ETM+ data of two megacity areas in China. Results demonstrated that the proposed method outperformed the use of spectral information alone and the joint use of the spectral information and the GLCM texture. In particular, the inclusion of multivariate variogram textures with spectral angle distance achieved the best results. The proposed method provides an effective way of extracting urban built-up areas from Landsat series images and could be applicable to other applications.

  16. SVM Classification of Urban High-Resolution Imagery Using Composite Kernels and Contour Information

    Full Text Available The classification of remote sensing images has done great forward taking into account the image’s availability with different resolutions, as well as an abundance of very efficient classification algorithms. A number of works have shown promising results by the fusion of spatial and spectral information using Support Vector Machines (SVM which are a group of supervised classification algorithms that have been recently used in the remote sensing field, however the addition of contour information to both spectral and spatial information still less explored. For this purpose we propose a methodology exploiting the properties of Mercer’s kernels to construct a family of composite kernels that easily combine multi-spectral features and Haralick texture features as data source. The composite kernel that gives the best results will be used to introduce contour information in the classification process. The proposed approach was tested on common scenes of urban imagery. The three different kernels tested allow a significant improvement of the classification performances and a flexibility to balance between the spatial and spectral information in the classifier. The experimental results indicate a global accuracy value of 93.52%, the addition of contour information, described by the Fourier descriptors, Hough transform and Zernike moments, allows increasing the obtained global accuracy by 1.61% which is very promising.

    To deal with the problem of urban ground object information extraction, the paper proposes an object-oriented classification method using aerial image and LiDAR data. Firstly, we select the optimal segmentation scales of different ground objects and synthesize them to get accurate object boundaries. Then, this paper uses ReliefF algorithm to select the optimal feature combination and eliminate the Hughes phenomenon. Eventually, the multiple classifier combination method is applied to get the outcome of the classification. In order to validate the feasible of this method, this paper selects two experimental regions in Stuttgart and Germany (Region A and B, covers 0.21 km2 and 1.1 km2 respectively). The aim of the first experiment on the Region A is to get the optimal segmentation scales and classification features. The overall accuracy of the classification reaches to 93.3 %. The purpose of the experiment on region B is to validate the application-ability of this method for a large area, which is turned out to be reaches 88.4 % overall accuracy. In the end of this paper, the conclusion shows that the proposed method can be performed accurately and efficiently in terms of urban ground information extraction and be of high application value.

  18. Willingness-to-Pay for Community-Based Health Insurance among Informal Workers in Urban Bangladesh.

    Full Text Available Reliance on out-of-pocket payment for healthcare may lead poor households to undertake catastrophic health expenditure, and risk-pooling mechanisms have been recommended to mitigate such burdens for households in Bangladesh. About 88% of the population of Bangladesh depends on work in the informal sector. We aimed to estimate willingness-to-pay (WTP for CBHI and identify its determinants among three categories of urban informal workers rickshaw-pullers, shopkeepers and restaurant workers.The bidding game version of contingent valuation method was used to estimate weekly WTP. In three urban locations 557 workers were interviewed using a structured questionnaire during 2010 and 2011. Multiple-regression analysis was used to predict WTP by demographic and household characteristics, occupation, education level and past illness.WTP for a CBHI scheme was expressed by 86.7% of informal workers. Weekly average WTP was 22.8 BDT [Bangladeshi Taka; 95% confidence interval (CI 20.9-24.8] or 0.32 USD and varied significantly across occupational groups (p = 0.000 and locations (p = 0.003. WTP was highest among rickshaw-pullers (28.2 BDT or 0.40 USD; 95% CI: 24.7-31.7, followed by restaurant workers (20.4 BDT 0.29 USD; 95% CI: 17.0-23.8 and shopkeepers (19.2 BDT or 0.27 USD; 95% CI: 16.1-22.4. Multiple regression analysis identified monthly income, occupation, geographical location and educational level as the key determinants of WTP. WTP increased 0.196% with each 1% increase in monthly income, and was 26.9% lower among workers with up to a primary level of education versus those with higher than primary, but less than one year of education.Informal workers in urban areas thus are willing to pay for CBHI and socioeconomic differences explain the magnitude of WTP. The policy maker might think introducing community-based model including public-community partnership model for healthcare financing of informal workers. Decision making regarding the implementation

    Health professionals cannot address public health issues effectively unless they have immediate access to current biomedical information. This paper reports on one mode of access, the Chicago AIDS Outreach Project, which was supported by the National Library of Medicine through outreach awards in 1995 and 1996. The three-year project is an effort to link the programs and services of the University of Illinois at Chicago Library of the Health Sciences and the Midwest AIDS Training and Education Center with the clinic services of community-based organizations in Chicago. The project was designed to provide electronic access to AIDS-related information for AIDS patients, the affected community, and their care givers. The project also provided Internet access and training and continued access to library resources. The successful initiative suggests a working model for outreach to health professionals in an urban setting.

    This study uses urban legends to examine the effects of the social information bias and survival information bias on cultural transmission across three phases of transmission: the choose-to-receive phase, the encode-and-retrieve phase, and the choose-to-transmit phase. In line with previous research into content biases, a linear transmission chain design with 60 participants aged 18-52 was used to examine the encode-and-retrieve phase, while participants were asked to rank their interest in reading the story behind a headline and passing a story on for the other two phases. Legends which contained social information (Social Type), legends which contained survival information (Survival Type), and legends which contained both forms of information (Combined Type) were all recalled with significantly greater accuracy than control material, while Social and Combined Type legends were recalled with significantly greater accuracy than Survival Type legends. In another study with 30 participants aged 18-22, no significant differences were found between legend types in either the choose-to-receive phase or the choose-to-transmit phase.

    Directory of Open Access Journals (Sweden)

    John Parr

    Full Text Available OBJECTIVES: Describe informal allopathic practitioner (IAP knowledge and practice about management of hypertension and identify gaps in IAP knowledge and practice amenable to interventions. METHODS: A cross sectional descriptive survey of 642 IAPs in Kamalapur (urban and Mirsarai (rural Bangladesh was conducted from March to April, 2011. Using a structured, pre-tested questionnaire sociodemographic, training, knowledge and practice data about management of hypertension was collected. Comparative statistics were preformed to show differences between urban and rural practitioners using SAS 8.0. FINDINGS: 99.4% of IAPs were male, mean age was 37.5 (12.5 SD years. Greater than 65% correctly identified the upper limit of normal blood pressure. 50.2% underestimated lower limit of systolic hypertension. 79.8% allowed age to affect their treatment approach. As blood pressure increased, willingness to treat with medication decreased and tendency to refer increased. Sedative/sleeping pills, antidepressants, and beta blockers were the most commonly prescribed medications for prehypertension (58.7%, 50.3% and 53.7% respectively, stage I hypertension (55.0%, 38.6%, 49.8% respectively and stage II hypertension (42.4%, 23.7%, and 28.8% respectively. Rural IAPs were more likely than urban IAPs to treat (84.7% vs 77.7%, order tests (27.1% vs 6.0% and write prescriptions (60.4% vs 18.7%. CONCLUSION: While IAPs are crucial to Bangladesh's pluralistic healthcare system, gaps in knowledge and practice could cause unnecessary harm. To include IAPs in the public sector's fight against the chronic disease epidemic, interventions aimed at standardizing IAPs knowledge and practice will be essential. Successfully utilizing IAPs will have beneficial implications not only for Bangladesh, but for all developing countries.

    The urban impervious surface, an important part in the city system, has a great influence on theecologicalenvironment in urban areas. The coverage of it is an important indicator for the evaluation ofurbanization. TheRemotesensing data has prominent features such as information-rich and accurate and it can provide data basis for large area extraction of impervious surface. GF-1 satellite is the first satellite of high-resolution earth observation system in China. With the homemade GF-1 satellite remote sensing image date as a resolution, this research, by the combination of V-I-S model and linear spectral mixture model, has first made estimation on the impervious surface of Tianjin City and then employed the remote sensingimage date with high resolution to test the precision of the estimated results. The results not only show that this method will make high precision available, but also reveal that Tianjin City has a wide coverage of impervious surface in general level, especially a high coverage rate both in the center and the coastal areas. The average coverage of impervious surface of the Tianjin city is very high and the coverage of impervious surface in the center and the coastal areas of Tianjin city reach seventy percent.City managers can use these data to guide city management and city planning.

    Greater Dhaka 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-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 areas are projected in marshy areas modified by extensive, largely unengineered landfills. In many areas, these terrains bear unfavorable building ground conditions, and reliable geospatial information is a major prerequisite for risk-sensitive urban planning. 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 Greater Dhaka City area. Geospatial information have not been considered in the present DAP. Within the project, GSB prepared a detailed geomorphologic map matching the DAP both in areal extent and scale. The geomorphological setting can be used as an important spatial proxy for the characterization of the subsurface since highly segmented, elevated terraces consisting of consolidated sandy Pliocene deposits overlain by stiff Plio-Pleistocene sediments are sharply bordered by low lying-areas. The floodplain and marsh areas are consisting of thick, mechanically weak Holocene fluvial sandy-silty sediments that are sometimes alternated by organic layers. A first expert-based engineering geological reclassification of the geomorphological map resulting in five building ground suitability classes is highly supported by the spatial analysis of extensive archive borehole information consisting of depth-continuous standard

    The 3D urban geological information system has been a major part of the national urban geological survey project of China Geological Survey in recent years. Large amount of multi-source and multi-subject data are to be stored in the urban geological databases. There are various models and vocabularies drafted and applied by industrial companies in urban geological data. The issues such as duplicate and ambiguous definition of terms and different coding structure increase the difficulty of information sharing and data integration. To solve this problem, we proposed a national standard-driven information classification and coding method to effectively store and integrate urban geological data, and we applied the data dictionary technology to achieve structural and standard data storage. The overall purpose of this work is to set up a common data platform to provide information sharing service. Research progresses are as follows: (1) A unified classification and coding method for multi-source data based on national standards. Underlying national standards include GB 9649-88 for geology and GB/T 13923-2006 for geography. Current industrial models are compared with national standards to build a mapping table. The attributes of various urban geological data entity models are reduced to several categories according to their application phases and domains. Then a logical data model is set up as a standard format to design data file structures for a relational database. (2) A multi-level data dictionary for data standardization constraint. Three levels of data dictionary are designed: model data dictionary is used to manage system database files and enhance maintenance of the whole database system; attribute dictionary organizes fields used in database tables; term and code dictionary is applied to provide a standard for urban information system by adopting appropriate classification and coding methods; comprehensive data dictionary manages system operation and security.

    2008-01-01

    Taking Nanjing as a case, the paper explains the spatial behavior differences existing in the information technology use among different groups of residents and households, by virtue of analyzing the survey data of urban households in the 11 districts of Nanjing, from the social, spatial, life and other non-technical angles. Also it makes various analyses and evaluation quantitatively and qualitatively on the social and spatial effect of information technol-ogy. The results show that the new technology is changing the social spatial behaviors of urban residents. New behav-ioral spaces of urban family such as telecommuting, email and QQ have begun to emerge. With the help of Internet, the communication scope of families has expanded greatly, and more new forms of publicizing community information have begun to emerge. Telecommunication contact forms have been developing swiftly, and their frequencies of con-tact have been increasing dramatically.

    Full Text Available Digesting the data hose that cities are constantly producing is complex; data is usually structured with different criteria, which makes comparative analysis of multiple cities challenging. However, the publicly available data from the Spanish cadaster contains urban information in a documented format with common semantics for the whole territory, which makes these analyses possible. This paper uses the information about the 3D geometry of buildings, their use and their year of construction, stored in cadastral databases, to study the relation between the built environment (what the city is and the urban plan (what the city wants to become, translating the concepts of the cadastral data into the semantics of the urban plan. Different representation techniques to better understand the city from the pedestrians’ point of view and to communicate this information more effectively are also discussed.

  17. Evaluation of the 3d Urban Modelling Capabilities in Geographical Information Systems

    Science.gov (United States)

    Dogru, A. O.; Seker, D. Z.

    2010-12-01

    Geographical Information System (GIS) Technology, which provides successful solutions to basic spatial problems, is currently widely used in 3 dimensional (3D) modeling of physical reality with its developing visualization tools. The modeling of large and complicated phenomenon is a challenging problem in terms of computer graphics currently in use. However, it is possible to visualize that phenomenon in 3D by using computer systems. 3D models are used in developing computer games, military training, urban planning, tourism and etc. The use of 3D models for planning and management of urban areas is very popular issue of city administrations. In this context, 3D City models are produced and used for various purposes. However the requirements of the models vary depending on the type and scope of the application. While a high level visualization, where photorealistic visualization techniques are widely used, is required for touristy and recreational purposes, an abstract visualization of the physical reality is generally sufficient for the communication of the thematic information. The visual variables, which are the principle components of cartographic visualization, such as: color, shape, pattern, orientation, size, position, and saturation are used for communicating the thematic information. These kinds of 3D city models are called as abstract models. Standardization of technologies used for 3D modeling is now available by the use of CityGML. CityGML implements several novel concepts to support interoperability, consistency and functionality. For example it supports different Levels-of-Detail (LoD), which may arise from independent data collection processes and are used for efficient visualization and efficient data analysis. In one CityGML data set, the same object may be represented in different LoD simultaneously, enabling the analysis and visualization of the same object with regard to different degrees of resolution. Furthermore, two CityGML data sets

    Background The assembled data from a population could provide information on health trends within the population.The aim of this research was to extract and know basic health information from an urban professional population in Beijing.Methods Data analysis was carried out in a population who underwent a routine medical check-up and aged >20 years,including 30 058 individuals.General information,data from physical examinations and blood samples were collected in the same method.The health status was separated into three groups by the criteria generated in this study,i.e.,people with common chronic diseases,people in a sub-clinic situation,and healthy people.The proportion of both common diseases suffered and health risk distribution of different age groups were also analyzed.Results The proportion of people with common chronic diseases,in the sub-clinic group and in the healthy group was 28.6%,67.8% and 3.6% respectively.There were significant differences in the health situation in different age groups.Hypertension was on the top of list of self-reported diseases.The proportion of chronic diseases increased significantly in people after 35 years of age.Meanwhile,the proportion of sub-clinic conditions was decreasing at the same rate.The complex risk factors to health in this population were metabolic disturbances (61.3%),risk for tumor (2.7%),abnormal results of morphological examination (8.2%) and abnormal results of lab tests of serum (27.8%).Conclusions Health information could be extracted from a complex data set from the heath check-ups of the general population.The information should be applied to support prevention and control chronic diseases as well as for directing intervention for patients with risk factors for disease.

  19. Public engagement with information on renewable energy developments: The case of single, semi-urban wind turbines.

    Parks, J M; Theobald, K S

    2013-01-01

    This paper explores perceptions of public engagement with information on renewable energy developments. It draws on a case study of proposals by a major supermarket chain to construct single wind turbines in two semi-urban locations in the UK, analysing data from interviews with key actors in the planning process and focus groups with local residents. The paper concludes that key actors often had high expectations of how local people should engage with information, and sometimes implied that members of the public who were incapable of filtering or processing information in an organised or targeted fashion had no productive role to play in the planning process. It shows how the specific nature of the proposals (single wind turbines in semi-urban locations proposed by a commercial private sector developer) shaped local residents' information needs and concerns in a way that challenged key actors' expectations of how the public should engage with information.

    Full Text Available Information technology is developed to assist people in minimizing processing time, reducing errors, increasing the accuracy and simplifying the overall process. The process of recording, retrieving and displaying data and information can thus be easily and accurately undertaken. Information technology in its initial development, however, tends to be too costly and complicated to make a real particularly for people in developing countries. Fortunately, universities as the centers of innovation, can be a game changer for the adoption of the innovative processes, for the benefits of the community at large. In all Indonesian universities, this role is associated with a, so called Tri Dharma Perguruan Tinggi (Three Devotions of Higher Education, TDHE. This paper examines the acceptance of the collaborating officials and the obstacles i.e. internal and environmental factors. We proposed the use of GIS-based technology to coordinate the administrative units of local government at all levels, particularly the Kelurahan as the lowest hierarchy of the administrative unit in local government system. The Kelurahan will then be the spearhead in a local government system in Indonesia in promoting administrative services to all Citizens. We undertook an integrated training and tutorial for select official staff of the Kelurahan on the system. Evaluation of shows that the information system can be used to simplify the collaborators’ activities. The evaluation was done through in-depth interview to the collaborating officials. The collaborators interested in learning more about the system as an innovative way in providing service to the community as well as spatial data input to support urban planning and management.

    Malnutrition in sub-Saharan Africa contributes to high rates of childhood morbidity and mortality. However, little information on the nutritional status of children is available from informal settlements. During the period of post-election violence in Kenya during December 2007-March 2008, food shortages were widespread within informal settlements in Nairobi. To investigate whether food insecurity due to post-election violence resulted in high prevalence of acute and chronic malnutrition in children, a nutritional survey was undertaken among children aged 6-59 months within two villages in Kibera, where the Kenya Medical Research Institute/Centers for Disease Control and Prevention conducts population-based surveillance for infectious disease syndromes. During 25 March-4 April 2008, a structured questionnaire was administered to caregivers of 1,310 children identified through surveillance system databases to obtain information on household demographics, food availability, and child-feeding practices. Anthropometric measurements were recorded on all participating children. Indices were reported in z-scores and compared with the World Health Organization (WHO) 2005 reference population to determine the nutritional status of children. Data were analyzed using the Anthro software of WHO and the SAS. Stunting was found in 47.0% of the children; 11.8% were underweight, and 2.6% were wasted. Severe stunting was found in 23.4% of the children; severe underweight in 3.1%, and severe wasting in 0.6%. Children aged 36-47 months had the highest prevalence (58.0%) of stunting while the highest prevalence (4.1%) of wasting was in children aged 6-11 months. Boys were more stunted than girls (p development during the first two years of life. Food programmes in Kenya have traditionally focused on rural areas and refugee camps. The findings of the study suggest that tackling childhood stunting is a high priority, and there should be fostered efforts to ensure that malnutrition

    The recent release of standards for vehicular communications will hasten the development of smart cities in the following years. Many applications for vehicular networks, such as blocked road warnings or advertising, will require multi-hop dissemination of information to all vehicles in a region of interest. However, these networks present special features and difficulties that may require special measures. The dissemination of information may cause broadcast storms. Urban scenarios are especially sensitive to broadcast storms because of the high density of vehicles in downtown areas. They also present numerous crossroads and signal blocking due to buildings, which make dissemination more difficult than in open, almost straight interurban roadways. In this article, we discuss several options to avoid the broadcast storm problem while trying to achieve the maximum coverage of the region of interest. Specifically, we evaluate through simulations different ways to detect and take advantage of intersections and a strategy based on store-carry-forward to overcome short disconnections between groups of vehicles. Our conclusions are varied, and we propose two different solutions, depending on the requirements of the application.

    2011-01-01

    American Indian/Alaska Native (AI/AN) urban youths experience significant mental health and substance use problems. However, culturally relevant treatment approaches that incorporate community perspectives within the urban setting are limited. This study analyzes community perspectives from AI/AN parents, AI/AN youths, and services providers within Los Angeles County. Information gathered was utilized to develop a needs assessment for AI/AN youths with mental health and substance use problems and to design a community-informed treatment approach. Nine focus groups and key informant interviews were conducted. The Los Angeles County community strongly expressed the need for providing urban AI/AN youths with traditional healing services and cultural activities within their treatment program. However, various barriers to accessing mental health and substance abuse treatment services were identified. An integrated treatment approach was subsequently designed as a result of input derived from community perspectives. The community believed that providing urban AI/AN youths with an integrated treatment approach has the potential to decrease the risk of mental health and substance abuse problems in addition to enhancing their cultural identity and self esteem.

    2014-06-01

    Full Text Available The primarily neuronal RNA-binding protein HuD is implicated in learning and memory. Here, we report the identification of several HuD target transcripts linked to Alzheimer’s disease (AD pathogenesis. HuD interacted with the 3′ UTRs of APP mRNA (encoding amyloid precursor protein and BACE1 mRNA (encoding β-site APP-cleaving enzyme 1 and increased the half-lives of these mRNAs. HuD also associated with and stabilized the long noncoding (lncRNA BACE1AS, which partly complements BACE1 mRNA and enhances BACE1 expression. Consistent with HuD promoting production of APP and APP-cleaving enzyme, the levels of APP, BACE1, BACE1AS, and Aβ were higher in the brain of HuD-overexpressing mice. Importantly, cortex (superior temporal gyrus from patients with AD displayed significantly higher levels of HuD and, accordingly, elevated APP, BACE1, BACE1AS, and Aβ than did cortical tissue from healthy age-matched individuals. We propose that HuD jointly promotes the production of APP and the cleavage of its amyloidogenic fragment, Aβ.

  13. [Mechanisms of articulation between the informal and the formal urban sectors].

    Lomnitz, L

    1978-01-01

    This article utilizes field data from Mexico City squatter settlements and personal interviews with employers to analyze some aspects of social relations between the informal sector and the formal urban sector, and compares the results with findings of other anthropologists in Mexico and elsewhere to derive a series of theoretical generalizations concerning mechanisms of articulation between the marginal sector and the formal economic and political institutions of the society. The formal sector is postulated to consist of the 3 subsectors of power, capital, and labor, which are in permanent conflict among themselves but all of which enjoy labor security and an assured minimal level of income. The marginal or informal sector lacks employment security, a minimal income level, and bargaining power. It is characterized by a small scale economy utilizing intensive familial labor. The informal sector is marginal to the dominant industrial system of production and the state apparatus, although it fulfills functions in terms of the national economy. 2 types of relationships may be distinguished in the social organization of the marginal sector: reciprocal relations between equals which form a network for the exchange of goods and services, or patron/client relations which are used, for example, in the case of petty entrepreneurs utilizing their relatives and acquaintances to create units of production. The functions of reciprocal relations are affected by social, physical, economic, and psychosocial distance or proximity and may result in exchanges of information, labor assistance, loans, services, or moral support. Patron/client relations may be direct, or the "patron" may be an intermediary. Some reciprocal networks display a pattern of incipient asymmetry leading to formation of true patron/client ties and some petty entrepreneurs or intermediaries manage to develop true patron/client networks; case histories are used to illustrate both phenomena.

    2014-10-01

    Full Text Available This paper deals with employment opportunities in the urban areas of Indonesia. The informal sector is present in almost every city in this country. The existence of the informal sector is usually associated with the lack of labour absorption capacity of the formal (modern sector. The informal sector serves as a buffer against the lack of formal employment opportunities and the consequent unemployment. Nearly one third of the working force in Indonesia cities work in the informal sector Those active in this sector usually are in the fully economically productive age brackets. The Informal sector can serve as a buffer power against the employment opportunity and unemployment. This can be seen from the fact that nearly one third of the working labour in cities work at the informal sector. Whereas, those who are engaged in the informal sector are at the fully productive age.

    2012-01-01

    Preventing the breakup of the American Indian family is the fundamental goal of the Indian Child Welfare Act (ICWA). However, few models exist to provide CPS workers and other practitioners with effective and practical strategies to help achieve this goal. This article presents a collaborative and trauma-informed family preservation practice model for Indian Child Welfare services with urban-based American Indian families. The model encompasses both systemic and direct practice efforts that assist families facing multiple challenges in creating a nurturing and more stable family life. System-level interventions improve the cultural responsiveness of providers, encourage partnerships between CPS and community-based providers, and support ICWA compliance. Direct practice interventions, in the form of intensive case management and treatment services, help parents/caregivers become more capable of meeting their own and their children's needs by addressing challenges such as substance abuse, trauma and other mental health challenges, domestic violence, and housing instability. Evaluation of the practice model suggests that it shows promise in preventing out-of-home placement of Native children, while at the same time improving parental capacity, family safety, child well-being, and family environment.

    A head-up display (HUD) and an inertial reference unit (IRU) were developed by the National Aerospace Laboratory (NAL) for the NAL QSTOL (Quiet Short Take Off and Landing) experimental air craft (Aska). In order to evaluate both the performance of the HUD which provides the pilot with landing aid information, and the accuracy and characteristics of the IRU to be used for flight control and measurements, flight tests were conducted on board the B-65 Queen Air research aircraft. The results indicated that the characteristics of the HUD as an approach and landing aid system were good, and also that the IRU was useful as a sensor for flight control and measurements. Furthermore, it was shown that fundamental methods of evaluating the HUD characteristics and the IRU accuracy in actual flight were established for application of the HUD and the IRU to a new aircraft in the future. In addition, possibility of a new technology with landing aid information by means of the HUD was made clear. 21 refs., 48 figs., 14 tabs.

    2016-10-01

    Design and analysis of an optical system is often a multidisciplinary task, and can involve the use of specialized software packages for imaging, mechanics, and illumination. This paper will present a case study on the design and analysis of a basic heads-up display (HUD) for automotive use. The emphasis will be on the special requirements of a HUD visual system and on the tools and techniques needed to accomplish the design. The first section of this paper will present an overview of the imaging design using commercially available imaging design software. Topics addressed in this section include modeling the windshield, visualizing the imaging performance, using constraints and freeform surfaces to improve the system, and meeting specific visual performance specifications with design/analysis methods. The second section will address the use of a CAD program to design a basic mechanical structure to support and protect the optics. This section will also discuss some of the issues and limitations involved in translating data between a CAD program and a lens design or illumination program. Typical issues that arise include the precision of optical surface prescriptions, surface and material properties, and the management of large data files. In the final section, the combined optical and mechanical package will be considered, using an illumination design program for stray light analysis. The stray light analysis will be directed primarily toward finding, visualizing, and quantifying unexpected ray paths. Techniques for sorting optical ray paths by path length, power, and elements or materials encountered will be discussed, along with methods for estimating the impact of stray light on the optical system performance.

    Informal science education institutions (ISEIs) are critical partners in public science education, as they support the science efforts of school systems by providing authentic opportunities for scientific inquiry. This study reports findings from an evaluation of urban advantage (UA), a collaboration between the New York City Department of Education and eight ISEIs designed to improve science education in New York City (NYC) middle schools. Now in its 10th year, the program harnesses the resources and expertise of NYC's ISEIs to (a) enhance the science content knowledge of middle school science teachers, (b) develop teachers' skills at using inquiry-based approaches in their classrooms, and (c) improve the science achievement of middle school students. We examine whether the UA program has led to increased student achievement on the eighth-grade New York State standardized science exam for students in participating schools; in supplemental analyses, we examine the effects on longer term (ninth-grade) outcomes. We use a difference-in-differences framework with school fixed effects to estimate the impact of attending a UA school in eighth grade on science achievement. Our key outcome is performance on New York State's eighth-grade intermediate-level science assessment; longer term outcomes include enrollment at specialized science, technology, engineering, and math high schools as well as taking and passing the high school (Regents) science exams. We find that attending a UA school increases student performance on the eighth-grade science exam by approximately 0.05 SD, and there is some evidence of small effects on Regents taking and passing rates. © The Author(s) 2014.

    Full Text Available Background: Regular IEC programs during antenatal and intranatal period, through individual or group approach, brings desirable changes in health practices of people, resulting in a healthy mother and a healthy baby. Materials and Methods: This study was conducted to assess the level of IEC services regarding pregnancy and child care, received by the women at an MCH clinic of an urban health center, where the study subjects comprised 400 antenatal (AN and postnatal (PN women and mothers of children under five years. Results: Warning signs of danger was explained to only 10% of the AN and PN women. Advice regarding family planning appeared to be the most frequently covered, though that too was explained to less than half of the subjects. About one third of the women were advised on breast feeding. Only 8% of the mothers had been told about all issues regarding pregnancy and child care. Breast feeding and weaning was properly explained to 85.7 and 81.1% of the total mothers of U5 children. Advice regarding subsequent nutrition was given to 60.9% of mothers. About only a quarter of the total mothers were advised on home management of diarrhea and acute respiratory infections. Very few mothers were counseled about the growth pattern of the children and none were shown the growth chart. Only 12.9% of the mothers were informed about all issues. Conclusion: IEC regarding maternal and child care other than feeding practices is a neglected service in the health facility where the study was conducted.

    Widespread human development has led to impairment of freshwater coastal wetlands and embayments, which provide critical and unique habitat for many freshwater fish species. This is particularly evident in the Laurentian Great Lakes, where such habitats have been severely altered over the last century as a result of industrial activities, urbanization, dredging and infilling. In Toronto Harbour, extensive restoration efforts have been directed towards improving the amount and quality of aquatic habitat, especially for fishes. To evaluate the effectiveness of this restoration work, use of the restored area by both target species and the fish community as a whole must be assessed. Individuals from four species (Common Carp, Largemouth Bass, Northern Pike and Yellow Perch) were tagged and tracked continuously for 1 year using an acoustic telemetry array in Toronto Harbour area of Lake Ontario. Daily site fidelity was estimated using a mixed-effects logistic regression model. Daily site fidelity was influenced by habitat restoration and its interactions with species and body size, as well as season and its interactions with species and body size. Daily site fidelity was higher in restored sites compared to non-restored sites for Yellow Perch and Northern Pike, but lower for Largemouth Bass and Common Carp. For all species, daily site fidelity estimates were highest during the summer and lowest during autumn. The approach used here has merit for evaluating restoration success and informing future habitat management activities. Creating diverse habitats that serve multiple functions and species are more desirable than single-function-oriented or single-species-oriented designs.

    Research in urban water management has experienced a transition from traditional model applications to modelling water cycles as an integrated part of urban areas. This includes the interlinking of models of many research areas (e.g. urban development, socio-economy, urban water management). The integration and simulation is realized in newly developed frameworks (e.g. DynaMind and OpenMI) and often assumes a high knowledge in programming. This work presents a Web based urban water management modelling platform which simplifies the setup and usage of complex integrated models. The platform is demonstrated with a small application example on a case study within the Alpine region. The used model is a DynaMind model benchmarking the impact of newly connected catchments on the flooding behaviour of an existing combined sewer system. As a result the workflow of the user within a Web browser is demonstrated and benchmark results are shown. The presented platform hides implementation specific aspects behind Web services based technologies such that the user can focus on his main aim, which is urban water management modelling and benchmarking. Moreover, this platform offers a centralized data management, automatic software updates and access to high performance computers accessible with desktop computers and mobile devices.

    In rapidly urbanizing old cities underground utility maps or urban utility information systems seldom exist. Close range remote sensing using Ground penetrating radar (GPR) for detection of the buried utilities is increasingly becoming common. GPR can help in developing or supplementing and updating an urban utility information system. The GPR data (radargram) needs to be interpreted by applying knowledge of buried utility responses under the influence of (a) antenna center frequency (b) host medium relative permittivity, conductivity and (c) object shape, size and material. In view of impracticality of generating utility response information directly in the field, Finite difference time domain (FDTD) simulation of radar wave propagation is carried out. The present work describes the database generation of GPR responses through simulation using an exclusive software GprMaxV2.0. A buried utility pipe produces a hyperbolic pattern in the radargram. In general, utilities may be made of metal, concrete or PVC; may lie within a shallow depth of about 0.5m-1.0m and their diameters may range upto to 1.0m; the relative permittivity of a dry soil could vary from about 4 to 15. Considering these aspects, problem of a pipe buried in soil is formulated, radargrams are simulated and variations of amplitudes and hyperbolic patterns are studied. To minimize the time-intensive simulations, Response surface method (RSM) is used to model amplitudes and hyperbolic patterns as functions of their influencing parameters. A database of simulated responses along with RSM modeling is seen to be a useful component of or complement to an urban utility information system.

    The World Health Organisation (WHO) recommends exclusive breastfeeding during the first six months of life for optimal growth, development and health. Breastfeeding should continue up to two years or more and nutritionally adequate, safe, and appropriately-fed complementary foods should be introduced at the age of six months to meet the evolving needs of the growing infant. Little evidence exists on breastfeeding and infant feeding practices in urban slums in sub-Saharan Africa. Our aim was to assess breastfeeding and infant feeding practices in Nairobi slums with reference to WHO recommendations. Data from a longitudinal study conducted in two Nairobi slums are used. The study used information on the first year of life of 4299 children born between September 2006 and January 2010. All women who gave birth during this period were interviewed on breastfeeding and complementary feeding practices at recruitment and this information was updated twice, at four-monthly intervals. Cox proportional hazard analysis was used to determine factors associated with cessation of breastfeeding in infancy and early introduction of complementary foods. There was universal breastfeeding with almost all children (99%) having ever been breastfed. However, more than a third (37%) were not breastfed in the first hour following delivery, and 40% were given something to drink other than the mothers' breast milk within 3 days after delivery. About 85% of infants were still breastfeeding by the end of the 11th month. Exclusive breastfeeding for the first six months was rare as only about 2% of infants were exclusively breastfed for six months. Factors associated with sub-optimal infant breastfeeding and feeding practices in these settings include child's sex; perceived size at birth; mother's marital status, ethnicity; education level; family planning (pregnancy desirability); health seeking behaviour (place of delivery) and; neighbourhood (slum of residence). The study indicates poor

    Full Text Available High-resolution satellite imagery provides an important new data source for building extraction. We demonstrate an integrated strategy for identifying buildings in 1-meter resolution satellite imagery of urban areas. Buildings are extracted using structural, contextual, and spectral information. First, a series of geodesic opening and closing operations are used to build a differential morphological profile (DMP that provides image structural information. Building hypotheses are generated and verified through shape analysis applied to the DMP. Second, shadows are extracted using the DMP to provide reliable contextual information to hypothesize position and size of adjacent buildings. Seed building rectangles are verified and grown on a finely segmented image. Next, bright buildings are extracted using spectral information. The extraction results from the different information sources are combined after independent extraction. Performance evaluation of the building extraction on an urban test site using IKONOS satellite imagery of the City of Columbia, Missouri, is reported. With the combination of structural, contextual, and spectral information, 72.7% of the building areas are extracted with a quality percentage 58.8%.

    This study uses a 4-year (2006-2009) cross-section of epidemiological burn injury data from Georgia and South Carolina. The results from the study show that the burn patients from rural areas differ from their urban counterparts in terms of relative burn injury incidence. Younger population groups that live in lower socioeconomic status communities especially in the urban areas are at a higher risk than other population groups. The differences in the types of burns in the urban-rural communities can give us further insights to the patients' association with injury sites. The presence of fewer burn injury treatment and care facilities in rural areas and the high incidence of burn in low-income communities in the urban areas should carry important policy implications for health planners. This study will enable researchers to understand the epidemiology of burn injuries at the local and national levels in the United States. It also carries important implications for using Geographic Information Systems for studying spatial distribution of burn injuries for disaster planning and mitigation of burn injuries.

    Research, development, test, and evaluation of flight deck interface technologies is being conducted by NASA to proactively identify, develop, and mature tools, methods, and technologies for improving overall aircraft safety of new and legacy vehicles operating in the Next Generation Air Transportation System (NextGen). Under NASA's Aviation Safety Program, one specific area of research is the use of small Head-Worn Displays (HWDs) as a potential equivalent display to a Head-up Display (HUD). Title 14 of the US CFR 91.175 describes a possible operational credit which can be obtained with airplane equipage of a HUD or an "equivalent"' display combined with Enhanced Vision (EV). A successful HWD implementation may provide the same safety and operational benefits as current HUD-equipped aircraft but for significantly more aircraft in which HUD installation is neither practical nor possible. A flight test was conducted to evaluate if the HWD, coupled with a head-tracker, can provide an equivalent display to a HUD. Approach and taxi testing was performed on-board NASA's experimental King Air aircraft in various visual conditions. Preliminary quantitative results indicate the HWD tested provided equivalent HUD performance, however operational issues were uncovered. The HWD showed significant potential as all of the pilots liked the increased situation awareness attributable to the HWD's unique capability of unlimited field-of-regard.

    The recent emergence of low-cost microsensors measuring various air pollutants has significant potential for carrying out high-resolution mapping of air quality in the urban environment. However, the data obtained by such sensors are generally less reliable than that from standard equipment and they are subject to significant data gaps in both space and time. In order to overcome this issue, we present here a data fusion method based on geostatistics that allows for merging observations of air quality from a network of low-cost sensors with spatial information from an urban-scale air quality model. The performance of the methodology is evaluated for nitrogen dioxide in Oslo, Norway, using both simulated datasets and real-world measurements from a low-cost sensor network for January 2016. The results indicate that the method is capable of producing realistic hourly concentration fields of urban nitrogen dioxide that inherit the spatial patterns from the model and adjust the prior values using the information from the sensor network. The accuracy of the data fusion method is dependent on various factors including the total number of observations, their spatial distribution, their uncertainty (both in terms of systematic biases and random errors), as well as the ability of the model to provide realistic spatial patterns of urban air pollution. A validation against official data from air quality monitoring stations equipped with reference instrumentation indicates that the data fusion method is capable of reproducing city-wide averaged official values with an R(2) of 0.89 and a root mean squared error of 14.3 μg m(-3). It is further capable of reproducing the typical daily cycles of nitrogen dioxide. Overall, the results indicate that the method provides a robust way of extracting useful information from uncertain sensor data using only a time-invariant model dataset and the knowledge contained within an entire sensor network.

    The head-up display system (HUM) has been developed for the windshield of Nissan Motor's passenger car, '88 model of Silvia (240SX) and '89 model of Maxima. HUD consists of a projector with high brightness VFT and a combiner which is a light-selective reflective film applied on the surface of ' e windshield. The system provides nice display legibility of speed in a three-digit reap at the position more than one meter far from driver's eye even under the bright sunlight. In this report, we present the optical properties and manufacturing process of the advanced combiner. The combiner has to have high transmittance as well as high reflectance so that a driver can see both foreground object and display reading at the same time. The optical design for the combiner is based on the concepts: (a) Visible light transmittance has to be 70% or more in accordance with a legal requirement, and (b) taking both peak wavelengths of Vim' and sensitivity characteristics of human eyes into consideration, 530nm of wave length is chosen as a reflective light. The combiner consists of a dielectric thin layer of Ti02-Si02 system. Its basic structure is decided by simulation with matrix method of the resultant waves. The coating film is applied on the restricted area of the forth surface of laminated windshield by newly developed solgel printing process using a metal alkoxide solution with a relatively long storage life.

    2016-06-01

    Informal settlements are a common occurrence in South Africa, and to improve in-situ circumstances of communities living in informal settlements, upgrades and urban design processes are necessary. Spatial data and maps are essential throughout these processes to understand the current environment, plan new developments, and communicate the planned developments. All stakeholders need to understand maps to actively participate in the process. However, previous research demonstrated that map literacy was relatively low for many planning professionals in South Africa, which might hinder effective planning. Because 3D visualizations resemble the real environment more than traditional maps, many researchers posited that they would be easier to interpret. Thus, our goal is to investigate the effectiveness of 3D geovisualizations for urban design in informal settlement upgrading in South Africa. We consider all involved processes: 3D modelling, visualization design, and cognitive processes during map reading. We found that procedural modelling is a feasible alternative to time-consuming manual modelling, and can produce high quality models. When investigating the visualization design, the visual characteristics of 3D models and relevance of a subset of visual variables for urban design activities of informal settlement upgrades were qualitatively assessed. The results of three qualitative user experiments contributed to understanding the impact of various levels of complexity in 3D city models and map literacy of future geoinformatics and planning professionals when using 2D maps and 3D models. The research results can assist planners in designing suitable 3D models that can be used throughout all phases of the process.

    A poorly designed urban solid waste collection system has an enormous impact on labour, operational and transport costs, and on society in general due to road contamination and negative effects on public health and the environment. This study proposes a methodology for designing an urban solid waste collection system. This methodology uses combinatorial optimisation and integer programing, and GIS tools to minimise collection time, and operational and transport costs while enhancing the current solid waste collection system. This methodology establishes feasible collection routes, determines an adequate vehicle fleet size and presents a comparative cost and sensitivity analysis of the results. The implementation of this methodology in a study case of a zone in Santiago yields significant cost savings in the total collection system.

  20. Informal support for women and intimate partner violence: the crucial yet ambivalent role of neighbours in urban India.

    Snell-Rood, Claire

    2015-01-01

    Women who experience intimate partner violence often rely on informal support to mitigate intimate partner violence's health effects. Yet there is little known about who gives the support and how it is provided. This paper explores from whom and how low-income women experiencing domestic violence in urban India seek informal support. In South Asia, women's reliance on kin for support is culturally valued, yet the urban social context makes it more likely that they will access such support from non-kin when they experience intimate partner violence. The paper draws on observations and interviews with 10 families collected over 14 months of in-depth ethnographic research in one Delhi slum community. Using a case study approach to explore women's responses to violence longitudinally, it was possible to track how women drew on support. Results show that even as women sought emotional support and direct intervention from their neighbours to deal with their domestic violence, they restricted these relationships, faced stigma, and emphasised the need to protect their families. Understanding the informal, but deeply ambivalent, systems of social support that women engage to deal with intimate partner violence is a first step toward strengthening such networks, a key recommendation to stem the health impacts of domestic violence.

  1. Citizen-Centric Urban Planning through Extracting Emotion Information from Twitter in an Interdisciplinary Space-Time-Linguistics Algorithm

    2016-07-01

    Full Text Available Traditional urban planning processes typically happen in offices and behind desks. Modern types of civic participation can enhance those processes by acquiring citizens’ ideas and feedback in participatory sensing approaches like “People as Sensors”. As such, citizen-centric planning can be achieved by analysing Volunteered Geographic Information (VGI data such as Twitter tweets and posts from other social media channels. These user-generated data comprise several information dimensions, such as spatial and temporal information, and textual content. However, in previous research, these dimensions were generally examined separately in single-disciplinary approaches, which does not allow for holistic conclusions in urban planning. This paper introduces TwEmLab, an interdisciplinary approach towards extracting citizens’ emotions in different locations within a city. More concretely, we analyse tweets in three dimensions (space, time, and linguistics, based on similarities between each pair of tweets as defined by a specific set of functional relationships in each dimension. We use a graph-based semi-supervised learning algorithm to classify the data into discrete emotions (happiness, sadness, fear, anger/disgust, none. Our proposed solution allows tweets to be classified into emotion classes in a multi-parametric approach. Additionally, we created a manually annotated gold standard that can be used to evaluate TwEmLab’s performance. Our experimental results show that we are able to identify tweets carrying emotions and that our approach bears extensive potential to reveal new insights into citizens’ perceptions of the city.

    We investigated the role of urban coyote feeding ecology in the transmission of Echinococcus multilocularis, the causative agent of Alveolar Echinococcosis in humans. As coyotes can play a main role in the maintenance of this zoonotic parasite within North American urban settings, such study can ultimately aid disease risk management. Between June 2012 and June 2013, we collected 251 coyote feces and conducted trapping of small mammals (n = 971) in five parks in the city of Calgary, Alberta, Canada. We investigated E. multilocularis epidemiology by assessing seasonal variations of coyote diet and the selective consumption of different rodent intermediate host species. Furthermore, accounting for small mammal digestibility and coyote defecation rates we estimated the number of small mammal preys ingested by coyote and consequently, coyote encounter rates with the parasite. Dominant food items included small mammals, fruit and vegetation, although hare and deer were seasonally relevant. The lowest frequency of occurrence per scat of small mammals was recorded in winter (39.4%), when consumption of deer was highest (36.4%). However, highest encounter rates (number of infected hosts predated/season) with E. multilocularis (95% CI: 1.0-22.4), combined with the lack of predation on non-competent small mammal species, suggest that winter is the critical season for transmission and control of this parasite. Within the small mammal assemblage, voles (Microtus pennsylvanicus and Myodes gapperi) were the selected preys of urban coyotes and likely played a key role for the maintenance of the urban sylvatic life-cycle of E. multilocularis in Calgary.

Furthermore, accounting for small mammal digestibility and coyote defecation rates we estimated the number of small mammal preys ingested by coyote and consequently, coyote encounter rates with the parasite. Dominant food items included small mammals, fruit and vegetation, although hare and deer were seasonally relevant. The lowest frequency of occurrence per scat of small mammals was recorded in winter (39.4%, when consumption of deer was highest (36.4%. However, highest encounter rates (number of infected hosts predated/season with E. multilocularis (95% CI: 1.0-22.4, combined with the lack of predation on non-competent small mammal species, suggest that winter is the critical season for transmission and control of this parasite. Within the small mammal assemblage, voles (Microtus pennsylvanicus and Myodes gapperi were the selected preys of urban coyotes and likely played a key role for the maintenance of the urban sylvatic life-cycle of E. multilocularis in Calgary.

  7. Population-based incidence of typhoid fever in an urban informal settlement and a rural area in Kenya: implications for typhoid vaccine use in Africa.

    Directory of Open Access Journals (Sweden)

    Robert F Breiman

    Full Text Available BACKGROUND: High rates of typhoid fever in children in urban settings in Asia have led to focus on childhood immunization in Asian cities, but not in Africa, where data, mostly from rural areas, have shown low disease incidence. We set out to compare incidence of typhoid fever in a densely populated urban slum and a rural community in Kenya, hypothesizing higher rates in the urban area, given crowding and suboptimal access to safe water, sanitation and hygiene. METHODS: During 2007-9, we conducted population-based surveillance in Kibera, an urban informal settlement in Nairobi, and in Lwak, a rural area in western Kenya. Participants had free access to study clinics; field workers visited their homes biweekly to collect information about acute illnesses. In clinic, blood cultures were processed from patients with fever or pneumonia. Crude and adjusted incidence rates were calculated. RESULTS: In the urban site, the overall crude incidence of Salmonella enterica serovar Typhi (S. Typhi bacteremia was 247 cases per 100,000 person-years of observation (pyo with highest rates in children 5-9 years old (596 per 100,000 pyo and 2-4 years old (521 per 100,000 pyo. Crude overall incidence in Lwak was 29 cases per 100,000 pyo with low rates in children 2-4 and 5-9 years old (28 and 18 cases per 100,000 pyo, respectively. Adjusted incidence rates were highest in 2-4 year old urban children (2,243 per 100,000 pyo which were >15-fold higher than rates in the rural site for the same age group. Nearly 75% of S. Typhi isolates were multi-drug resistant. CONCLUSIONS: This systematic urban slum and rural comparison showed dramatically higher typhoid incidence among urban children <10 years old with rates similar to those from Asian urban slums. The findings have potential policy implications for use of typhoid vaccines in increasingly urban Africa.

    This article presents original research on relations between middle-class residents and informal-sector workers in Delhi, India. It shows how middle-class associations used their consumption preferences as well as relationships with local authorities to legitimize the work of street hawkers and waste workers. These findings suggest that the toleration of informality can be traced to governance regimes comprised of both state and non-state powerbrokers.

    2016-06-01

    This report is a description of a balanced scorecard design and evaluation process conducted for the health information management department at an urban non-teaching hospital in Canada. The creation of the health information management balanced scorecard involved planning, development, implementation, and evaluation of the indicators within the balanced scorecard by the health information management department and required 6 months to complete. Following the evaluation, the majority of members of the health information management department agreed that the balanced scorecard is a useful tool in reporting key performance indicators. These findings support the success of the balanced scorecard development within this setting and will help the department to better align with the hospital's corporate strategy that is linked to the provision of efficient management through the evaluation of key performance indicators. Thus, it appears that the planning and selection process used to determine the key indicators within the study can aid in the development of a balanced scorecard for a health information management department. In addition, it is important to include the health information management department staff in all stages of the balanced scorecard development, implementation, and evaluation phases.

  12. ‘Men value their dignity’: securing respect and identity construction in urban informal settlements in South Africa

    Directory of Open Access Journals (Sweden)

    Andrew Gibbs

    2014-04-01

    Full Text Available Background: Urban informal settlements remain sites of high HIV incidence and prevalence, as well as violence. Increasing attention is paid on how configurations of young men's masculinities shape these practices through exploring how men build respect and identity. In this paper, we explore how young Black South Africans in two urban informal settlements construct respect and a masculine identity. Methods: Data are drawn from three focus groups and 19 in-depth interviews. Results: We suggest that while young men aspire to a ‘traditional’ masculinity, prioritising economic power and control over the household, we suggest that a youth masculinity emerges which, in lieu of alternative ways to display power, prioritises violence and control over men's sexual partners, men seeking multiple sexual partners and men's violence to other men. This functions as a way of demonstrating masculinity and their position within a public gender order. Discussion: We suggest there are three implications of the findings for working with men on violence and HIV-risk reduction. First, there exist a number of contradictions in men's discourses about masculinity that may provide spaces and opportunities for change. Second, it is important to work on multiple issues at once given the way violence, alcohol use, and sexual risk are interlinked in youth masculinity. Finally, engaging with men's exclusion from the capitalist system may provide an important way to reduce violence.

    2011-01-01

    Full Text Available Abstract Background Recent trends in global vaccination coverage have shown increases with most countries reaching 90% DTP3 coverage in 2008, although pockets of undervaccination continue to persist in parts of sub-Saharan Africa particularly in the urban slums. The objectives of this study were to determine the vaccination status of children aged between 12-23 months living in two slums of Nairobi and to identify the risk factors associated with incomplete vaccination. Methods The study was carried out as part of a longitudinal Maternal and Child Health study undertaken in Korogocho and Viwandani slums of Nairobi. These slums host the Nairobi Urban Health and Demographic Surveillance System (NUHDSS run by the African Population and Health Research Centre (APHRC. All women from the NUHDSS area who gave birth since September 2006 were enrolled in the project and administered a questionnaire which asked about the vaccination history of their children. For the purpose of this study, we used data from 1848 children aged 12-23 months who were expected to have received all the WHO-recommended vaccinations. The vaccination details were collected during the first visit about four months after birth with follow-up visits repeated thereafter at four month intervals. Full vaccination was defined as receiving all the basic childhood vaccinations by the end of 24 months of life, whereas up-to-date (UTD vaccination referred to receipt of BCG, OPV 1-3, DTP 1-3, and measles vaccinations within the first 12 months of life. All vaccination data were obtained from vaccination cards which were sighted during the household visit as well as by recall from mothers. Multivariate models were used to identify the risk factors associated with incomplete vaccination. Results Measles coverage was substantially lower than that for the other vaccines when determined using only vaccination cards or in addition to maternal recall. Up-to-date (UTD coverage with all vaccinations

    The research of urban flood risk assessment and management are of great academic and practical importance, which has become a widespread concern throughout the world. It’s significant to understand the spatial-temporal distribution of the flood risk before making the risk response measures. In this study, the urban region of Jingdezhen City is selected as the study area. The assessment indicators are selected from four aspects: disaster-causing factors, disaster-pregnant environment, disaster-bearing body and the prevention and mitigation ability, by consideration of the formation process of urban flood risk. And then, a small-scale flood disaster risk assessment model is developed based on Analytic Hierarchy Process(AHP) and Geographic Information System(GIS), and the spatial-temporal distribution of flood risk in Jingdezhen City is analysed. The results show that the risk decreases gradually from the centre line of Changjiang River to the surrounding, and the areas of high flood disaster risk is decreasing from 2010 to 2013 while the risk areas are more concentred. The flood risk of the areas along the Changjiang River is the largest, followed by the low-lying areas in Changjiang District. And the risk is also large in Zhushan District where the population, the industries and commerce are concentrated. The flood risk in the western part of Changjiang District and the north-eastern part of the study area is relatively low. The results can provide scientific support for flood control construction and land development planning in Jingdezhen City.

    Full Text Available With the unprecedented growth of urban population and urban development, we are faced with the growing trend of illegal building (IB construction. Field visit, as the currently used method of IB detection, is time and man power consuming, in addition to its high cost. Therefore, an automatic IB detection is required. Acquiring multi-temporal satellite images and using image processing techniques for automatic change detection is one of the optimum methods which can be used in IB monitoring. In this research an automatic method of IB detection has been proposed. Two-temporal panchromatic satellite images of IRS-P5 of the study area in a part of Tehran, the city map and an updated spatial database of existing buildings were used to detect the suspected IBs. In the pre-processing step, the images were geometrically and radiometrically corrected. In the next step, the changed pixels were detected using K-means clustering technique because of its quickness and less user’s intervention required. Then, all the changed pixels of each building were identified and the change percentage of each building with the standard threshold of changes was compared to detect the buildings which are under construction. Finally, the IBs were detected by checking the municipality database. The unmatched constructed buildings with municipal database will be field checked to identify the IBs. The results show that out of 343 buildings appeared in the images; only 19 buildings were detected as under construction and three of them as unlicensed buildings. Furthermore, the overall accuracies of 83%, 79% and 75% were obtained for K-means change detection, detection of under construction buildings and IBs detection, respectively.

Gli studi condotti dimostrano infatti che il tessuto urbano informale, il cui sviluppo prescinde da pianificazioni o da logiche normative, risulta però strettamente legato a dinamiche sociali ed economiche. Sotto questo punto di vista lo sviluppo della città informale contemporanea può essere messa a confronto con le dinamiche di formazione e trasformazione dei centri urbani pre-moderni, sottolineando la netta analogia che lega le trasformazioni urbane alle necessità e alle dinamiche sociali, proprie dell’intorno culturale in cui tali organismi urbani si identificano.Il riconoscimento di una logica di sviluppo di tali tessuti, diventa lo strumento in grado di guidarne la rigenerazione urbana, rispettandone la cultura abitativa. / This research start from the hypothesis that the design method, based on the study of urban morphology, can be a guide for urban interventions within the so-called 'informal' fabric. The studies demonstrate that the 'informal' city, the development of which is independent from urban design or legal rules, is closely related to social and economic dynamics. From this point of view the development of the contemporary informal city can be compared with the dynamics of formation and transformation of pre-modern urban fabric, emphasizing the analogy that links the urban transformation to the social needs, own of the surroundings cultural context in which these urban organisms are identified. The recognition of a logical development of these fabrics, becomes the tool that can guide the urban regeneration, respecting the living culture.

    Full Text Available This paper discusses the driving forces (DFs of informal urbanization (IU in the greater Cairo metropolitan region (GCMR using the Analytic Hierarchy Process (AHP. The IU patterns in the GCMR have been extremely influenced by seven DFs: geographical characteristics, availability of life facilities, economic incentives, land demand and supply, population increase, administrative function, and development plans. This research found that these forces vary significantly in how they influence urban growth in the three study sectors, namely, the middle, north, and south areas in the western part of the GCMR. The forces with the highest influence were economic incentives in the middle sector, population increase in the north sector, and the administrative function in the south sector. Due to the lower availability of buildable land in the middle sector, the land demand and supply force had a lesser influence in this sector compared to in the north and south sectors. The development plans force had medium influence in all sectors. The geographical characteristics force had little influence in both the middle and the north sectors, but higher influence than economic incentives, availability of life facilities, and development plans in the south sector. Because of the spatial variances in life facilities organizations in the GCMR, the life facilities availability force had little effect on IU in the south sector.

    Full Text Available Abstract Background There exists some research evidence regarding how adolescents utilize the Internet for health information seeking purposes. The purpose of this study is to understand how in-school and out-of-school adolescent girls in Owerri, Nigeria use online resources to meet their reproductive health information needs. The result could be considered very crucial in assessing the potential role of the Internet in providing health information to adolescent girls in a typical Nigerian urban city. Methods A questionnaire was used to collect data from 1011 adolescent girls in selected secondary schools in the communities, and also from 134 out-of-school girls selected from the same communities. Results More than 73% of the girls reported having ever used the Internet; more than 74% and 68% of them being in-school and out-of-school respectively. The in-school girls (43.9% reported having home access more than the out-of-school (5.6% although the out-of-school have used the Internet for finding reproductive and related information more than the in-school. While parents (66.22% and teachers (56.15% are the two sources most used to the in-school girls, friends (63.18% and the Internet (55.19% were reported by the out-of-school youth as the two most used sources of information to them. Conclusion The Internet is not a first choice of source of reproductive health information for both the in-school and out-of-school adolescent girls in Owerri, Nigeria. The source is however, more commonly used by the out-of-school than the in-school, but the in-school have a more favorable assessment of the quality of information they obtain from the Internet.

    Full Text Available It is widely recognized that social capital constitutes an important form of social regulation in informal sector and it is the major component of the asset portfolios of the urban poor.Nevertheless, the potential contribution of social capital in the informal sector remains under-investigated in African cities. Applying the network approach, this study examinedthe economic returns of social capital to microenterprises in the informal sector. To do so, the personal networks of street vendors in Addis Ababa were examined. Multi-stagesampling procedures involving purposive and systematic random-walk techniques were applied to draw samples. Data were collected through position generator surveys. The datawere analyzed using OLS and Instrumental Variable Estimators. By controlling the potential endogeneity, the estimation results revealed that network resources are positive and significant predictors of enterprise profit. But their benefit is less for married vendors than unmarried ones. The human capital measures such as education, vocational training, and business experience are not significant predictors of enterprise profit.Key Words: Social Capital, Social Networks, Informal Sector, Ethiopia, Addis Ababa

  13. [The dynamic of the informal urban sector in Mexico: the role of intersectoral mobility].

    Science.gov (United States)

    Roubaud, F

    1992-01-01

    This examination of labor mobility between the formal and informal sectors in Mexico provides a critique of existing models of intersectoral articulation, analyzes the flows between the formal and informal sectors of a group of small entrepreneurs in the informal sector, and assesses the consequences of existing mobility strategies for the economic performance of the informal sector. Works of economists interested in dual models of economies in developing countries do not deal directly with questions of intersectoral mobility, but they implicitly suggest a labor force with 2 closed compartments. But empirical studies in Latin America have demonstrated a strong rotation of workers between the 2 sectors. The functional theory proposed by H. Lopez is one of the most developed among a group that assert that movement between the modern and informal sectors is massive. The Lopez theory suggests that very young workers gain experience in small enterprises in the informal sector, become wage earners in the modern sector sometime in their 20s, and retire after 30 or 40 years to new employment in the informal sector. Very few studies on mobility between sectors have been done in Mexico. But a simulation model demonstrates that when age-related variations in total labor force participation are factored in, the life cycle model of intersectoral mobility is not valid, despite apparent support when the sectoral composition of the labor force is examined cross-sectionally and the results interpreted longitudinally. The National Survey of the Informal Economy was conducted among 2748 units employing fewer than 6 persons in Mexico City, Guadalajara, Monterrey, Puebla, Leon, Juarez, and Tijuana. The objective was not to study intersectoral mobility, and questions were asked only on the 2 most recent jobs rather than the entire work history. Only the "micro-entrepreneurs" themselves were interviewed, with the 33% of the work force comprising hired workers and unpaid family labor

    Westaway, M S; Viljoen, E; Rudolph, M J

    1999-04-01

    Interviews were conducted with 294 black residents (155 females and 138 males) of a peri-urban informal settlement in Gauteng to ascertain utilisation of oral health services, oral health needs and oral health status. Only 37 per cent of the sample had consulted a dentist or medical practitioner, usually for extractions. Teenagers and employed persons were significantly less likely to utilise dentists than the older age groups and unemployed persons. Forty per cent were currently experiencing oral health problems such as a sore mouth, tooth decay and bleeding/painful gums. Two hundred and twelve (73 per cent) interviewees wanted dental treatment or advice. Residents who rated their oral health status as fair or poor appeared to have the greatest need for oral health services. The use of interviews appears to be a cost-effective method of determining oral morbidity.

    Full Text Available Abstract Background Our intention was to analyze demographic and contextual factors associated with sexual risk taking among HIV-infected patients on antiretroviral treatment (ART in Africa's largest informal urban settlement, Kibera in Nairobi, Kenya. Methods We used a cross-sectional survey in a resource-poor, urban informal settlement in Nairobi; 515 consecutive adult patients on ART attending the African Medical and Research Foundation clinic in Kibera in Nairobi were included in the study. Interviewers used structured questionnaires covering socio-demographic characteristics, time on ART, number of sexual partners during the previous six months and consistency of condom use. Results Twenty-eight percent of patients reported inconsistent condom use. Female patients were significantly more likely than men to report inconsistent condom use (aOR 3.03; 95% CI 1.60-5.72. Shorter time on ART was significantly associated with inconsistent condom use. Multiple sexual partners were more common among married men than among married women (adjusted OR 4.38; 95% CI 1.82-10.51. Conclusions Inconsistent condom use was especially common among women and patients who had recently started ART, i.e., when the risk of HIV transmission is higher. Having multiple partners was quite common, especially among married men, with the potential of creating sexual networks and an increased risk of HIV transmission. ART needs to be accompanied by other preventive interventions to reduce the risk of new HIV infections among sero-discordant couples and to increase overall community effectiveness.

  4. Practice-Informed Approaches to Addressing Substance Abuse and Trauma Exposure in Urban Native Families Involved with Child Welfare.

    Lucero, Nancy M; Bussey, Marian

    2015-01-01

    Similar to families from other groups, urban-based American Indian and Alaska Native ("Native") family members involved with the child welfare system due to substance abuse issues are also often challenged by untreated trauma exposure. The link between these conditions and the history of genocidal policies aimed at destroying Native family ties, as well as experiences of ongoing discrimination, bring added dimensions for consideration when pro- viding services to these families. Practice-based evidence indicates that the trauma-informed and culturally responsive model developed by the Denver Indian Family Resource Center (DIFRC) shows promise in reducing out-of-home placements and re-referrals in urban Native families with substance abuse and child welfare concerns, while also increasing caregiver capabilities, family safety, and child well-being. This article provides strategies from the DIFRC approach that non-Native caseworkers and supervisors can utilize to create an environment in their own agencies that supports culturally based practice with Native families while incorporating a trauma-informed understanding of service needs of these families. Casework consistent with this approach demonstrates actions that meet the Active Efforts requirement of the Indian Child Welfare Act (ICWA) as well as sound clinical practice. Intensive and proactive case management designed specifically for families with high levels of service needs is a key strategy when combined with utilizing a caseworker brief screening tool for trauma exposure; training caseworkers to recognize trauma symptoms, making timely referrals to trauma treatment by behavioral health specialists experienced in working with Native clients, and providing a consistent service environment that focuses on client safety and worker trustworthiness. Finally, suggestions are put forth for agencies seeking to enhance their cultural responsiveness and include increasing workers' understanding of cultural values

    2011-01-01

    The three-period (1995, 1998 and 2003) remote sensing images in Jinan City, China are selected. And the information of green land, construction land, woodland and water body is extracted by using the image processing module of remote-sensing software and computerized interpretation module. Both the change table and transfer matrix table of land use area are analyzed by modeling module of remote-sensing software. Then, the Geo-information Tupu is obtained; and the temporal and spatial variation of land use in Jinan City is monitored and analyzed by Geo-information Tupu and transfer matrix. Result shows that land use structure change of Jinan City in the years 1995-1998 shows a transformation from green land to construction land. Area of green land circulating into construction land reaches 62.27 square kilometers, accounting for 25.84% of the initial green land. In the year 1998, areas of woodland and green land are reduced due to the urban expansion of Jinan City. However, with the enhancement of people’s awareness of environmental protection, areas of woodland and green land gradually increase in the year 2003, which are still less than those in the year 1995.

    Full Text Available Development instruments aiding the researchers are expressing a variety that only innovative capacity is able to render. Linked to these, information and communication capacities grew to support the evolution of new models in support of the researcher concerning acquiring new knowledge in the open context formed by his or she’s online connected colleagues. For a better development of the institutional capacity the best yielding base investment is in information and documentation, let that via subscriptions to the scientific databases, or becoming a service supplier for third persons/bodies. The rule of thumb says that to empower such base, a survey of the internal and external resources is needed, and the following efforts lead to a charting of the most visible and valuable information resources out there. Once this effort started, the steps taken to a consolidation as a research pole and as a service provider for quality information, will lead to a continuous evaluation and growth of the existing informational asset - the library.

  9. The Emergence of Informal Institutions among Internal Migrants in Urban China

    Directory of Open Access Journals (Sweden)

    Rumin Luo

    2016-01-01

    Full Text Available China’s dramatic economic development and urbanisation have led to an increase in its number of internal migrants. As of 2013, this group accounted for more than 20 per cent of the country’s population, and approximately 70 per cent of people in this group are working in the informal economy. This paper pays special attention to migrant-traders in the informal sector and the strategies they use in Shanghai. Migrants are doubly marginalised by the hukou (户口 and danwei (单位 systems in the megacity and have only limited access to social welfare. It is argued that the informal strategies of these marginalised actors develop in related patterns of social relationships and institutional constraints. Such strategies create new forms of informal institutions that are justified and gain legitimacy when countering unequal and hierarchical formal institutions and social arrangements. This paper empirically explores how informal institutions can act in parallel with or diverge from formal institutions, and how they might influence formal institutions in the long term.

  15. Robust planning of sanitation services in urban informal settlements: An analytical framework.

    Science.gov (United States)

    Schmitt, Rafael J P; Morgenroth, Eberhard; Larsen, Tove A

    2017-03-01

    New types of sanitation services are emerging to tackle the sanitation crisis in informal settlements. These services link toilet facilities to semi-decentralized treatment plants via frequent, road-based transport of excreta. However, information for the planning of such sanitation services is scarce, and their future operating conditions are highly uncertain. The key questions of this paper are therefore: a) what are the drivers behind success or failure of a service-based sanitation system in informal settlements and b) on what scales and under which conditions can such a system operate successfully? To answer these questions, already at an early stage of the planning process, we introduce a stochastic model to analyze a wide range of system designs under varying technical designs, socio-economic factors, and spatial condition. Based on these initial results, we design a sanitation service and use the numeric model to study its reliability and costs over a wide range of scales, i.e., system capacities, from very few to many hundred users per semi-decentralized treatment unit. Key findings are that such a system can only operate within a narrow, but realistic range of conditions. Key requirements are toilet facilities, which can be serviced rapidly, and a flexible workforce. A high density of facilities will also lower the costs. Under these premises, we develop a road-based sanitation service and model its functionality in different settings and under many scenarios. Results show that the developed sanitation system using a single vehicle is scalable (100-700 users), can provide reliable service, and can be cheap (<1.5 c/p/day). Hence, this paper demonstrates opportunities for road-based sanitation in informal settlements and presents a quantitative framework for designing such systems. Copyright © 2016 Elsevier Ltd.

    2017-09-01

    Full Text Available Advanced traveller information systems (ATIS are meant to assist people in their daily travel decisions as well as to prompt a shift from cars to alternative and more environmentally-friendly transport strategies. Not many comprehensive studies have been undertaken so far in order to assess the willingness to pay (WTP for ATIS, despite a development of these tools during the last two decades. This paper aims at analysing the WTP for Optymod’Lyon, a smartphone application which plans your journey travels using real-time information about all available transport modes. To this end, a quali-quantitative approach was adopted, administering a questionnaire to participants and organising focus groups before and after the test of the application. A sample of 42 people living in the metropolitan area of Lyon was involved. Results showed four clusters of participants: idealists, pragmatics, the ambiguous and opportunists. A strong majority of idealists and pragmatics were unwilling to pay, mainly for economic reasons and the availability on the market of free information. They record a lower share of trips to work and a higher share for leisure, shopping and study purposes. Those willing to pay (of which 37.8% were opportunists report a low monthly charge level (0.2–3 €/month and are mainly highly-educated car users, travelling for work.

    Full Text Available In the past several decades, Lagos Metropolis emerged as one of the fastesturbanizing cities in the West African Sub-region. In the absence of a regular use ofgeospatial information management systems, limited effort had been made to keep track ofchanges in the natural environment in the rapidly growing city for policy making in landadministration. The ubiquitous energy radiated by the rapid urbanization rate in the areanot only created unprecedented consequences by diminishing the quality of theenvironment and natural resources but it raises serious implications for land managementin the region. The factors fuelling the land crisis in the area which are not far fetchedconsists of socio-economic, ecological and policy elements. To tackle these issues in amega city, up-to-date knowledge would be required to capture and analyze landinformation trends. Such an effort will help manage the city’s expansion as well asinfrastructure development through the right choices in planning and (spatial designsusing the latest tools in geospatial technologies of Geographic Information Systems GISand remote sensing. This study investigates the spatial implications of the rapid expansionof metropolitan Lagos for land management using GIS and Remote sensing technology.The result of the research provides a valuable road map that can enable planners contributeto improved land administration necessary for effective management of natural resources.

  19. Using risk-based analysis and geographic information systems to assess flooding problems in an urban watershed in Rhode Island.

    Hardmeyer, Kent; Spencer, Michael A

    2007-04-01

    This article provides an overview of the use of risk-based analysis (RBA) in flood damage assessment, and it illustrates the use of Geographic Information Systems (GIS) in identifying flood-prone areas, which can aid in flood-mitigation planning assistance. We use RBA to calculate expected annual flood damages in an urban watershed in the state of Rhode Island, USA. The method accounts for the uncertainty in the three primary relationships used in computing flood damage: (1) the probability that a given flood will produce a given amount of floodwater, (2) the probability that a given amount of floodwater will reach a certain stage or height, and (3) the probability that a certain stage of floodwater will produce a given amount of damage. A greater than 50% increase in expected annual flood damage is estimated for the future if previous development patterns continue and flood-mitigation measures are not taken. GIS is then used to create a map that shows where and how often floods might occur in the future, which can help (1) identify priority areas for flood-mitigation planning assistance and (2) disseminate information to public officials and other decision-makers.

    2006-10-01

    Based on the introduction to the characters and constructing flow of space semantic model, the feature space and context of house information in high resolution remote sensing image are analyzed, and the house semantic network model of Quick Bird image is also constructed. Furthermore, the accuracy and practicability of space semantic model are checked up through extracting house information automatically from Quick Bird image after extracting candidate semantic nodes to the image by taking advantage of grey division method, window threshold value method and Hough transformation. Sample result indicates that its type coherence, shape coherence and area coherence are 96.75%, 89.5 % and 88 % respectively. Thereinto the effect of the extraction of the houses with rectangular roof is the best and that with herringbone and the polygonal roofs is just ideal. However, the effect of the extraction of the houses with round roof is not satisfied and thus they need the further perfection to the semantic model to make them own higher applied value.

    2012-07-01

    Full Text Available Information and communication technologies (ICTs have progressed rapidly during the last twenty years and the spatial effects of these technologies have been debated since 1980’s. Although there is no absolute consensus of opinion what the spatial impact will be on, all authorities and academics have agreed in respect of ICTs have important role on spatial structure. These improvements will impact both spatial development and spatial planning. In this context, in order to debate about the spatial effects of ICTs, basic factors this behind spatial change should be defined. The studies done upon the meaning of space, distance and time have showed that these factors are no longer a negative component by means of information networks and communication. In the literature there are a number of studies which deal with the development of the information society and the important role of ICTs in this process. On the other hand, the urban and spatial effects of these developments has been dealt with mostly only by researchers and this discussion has been highly modest among urban planners. This article explicates the need and possibilities to develop urban and regional planning discipline due to the impact of ICTs on urban and spatial change. The findings are based on the views represented in literature and on the opinions of Turkish urban planners. The objective of the field survey is to search for opinions of Turkish urban planners about the effects of the ICTs and its implications on the spatial developments of urban and rural areas and also urban planning. In the fieldwork, the opinions of Turkish planners were surveyed in a questionnaire for this article. The questionnaire contained different statements about the effects of ICTs on spatial development and the development of planning practices. Surveys were conducted to urban planners working in public and private institutions in Turkey. The likert scale was used to measure respondents’ attitudes

    Directory of Open Access Journals (Sweden)

    Patricia J. Zweig

    2017-01-01

    Full Text Available Community-based disaster risk management (CBDRM is an emancipatory approach that aims to empower local communities in reducing their own risks. A community risk assessment (CRA is an essential element of CBDRM, incorporating highly participatory processes of hazard identification and vulnerability analysis. By incorporating local knowledge and insights, together with those contributed by other external role players, the nature of local risks can be more accurately identified, giving consideration to their causal factors, the nature of their realised impacts or potential effects on a local community and the challenges posed in addressing them. Reflecting on the process and outcomes of a CRA conducted in an informal settlement in the Cape Town metropolitan area, this article describes how one such risk assessment contributed to building local agency through a process of collaborative engagement. Offered as an example of possible best practice, it illustrates both the immediate and potentially longer term benefits to be derived from such a collaborative process, suggesting that a community-based risk assessment may contribute significantly to building more resilient communities. It concludes with a consideration of the challenges of sustaining longer term risk reduction efforts.

    Sumenep City frequently hit by floods. Drainage network conditions greatly affect the performance of her maid, especially those aspects that affect the capacity of the drainage channel. Aspects that affect the capacity of the drainage channel in the form of sedimentation rate and complementary buildings on drainage channels, for example, the presence of street inlet and trash rack. The method used is a drainage channel capacity level approach that level assessment of each segment drainage network conditions by calculating the ratio of the channel cross-sectional area that is filled with sediment to the total cross-sectional area wet and the existence of complementary buildings. Having obtained the condition index value of each segment, the subsequent analysis is spatial analysis using ArcGIS applications to obtain a map of the drainage network information. The analysis showed that the level condition of drainage network in the city of Sumenep in 2016 that of the total 428 drainage network there are 43 sections belonging to the state level “Good”, 198 drainage network belong to the state level “Enough”, 115 drainage network belong to the state “Mild Damaged”, 50 sections belonging to the state “Heavy Damage” and 22 drainage network belong to the state of “Dysfunction”.

    Exposure to air pollutants such as volatile organic compounds (VOCs) and fine particulate matter (PM2.5) are associated with adverse health effects. This study applied multiple time resolution data of hourly VOCs and 24-h PM2.5 to a constrained Positive Matrix Factorization (PMF) model for source apportionment in Taipei, Taiwan. Ninety-two daily PM2.5 samples and 2208 hourly VOC measurements were collected during four seasons in 2014 and 2015. With some a priori information, we used different procedures to constrain retrieved factors toward realistic sources. A total of nine source factors were identified as: natural gas/liquefied petroleum gas (LPG) leakage, solvent use/industrial process, contaminated marine aerosol, secondary aerosol/long-range transport, oil combustion, traffic related, evaporative gasoline emission, gasoline exhaust, and soil dust. Results showed that solvent use/industrial process was the largest contributor (19%) to VOCs while the largest contributor to PM2.5 mass was secondary aerosol/long-range transport (57%). A robust regression analysis showed that secondary aerosol was mostly contributed by regional transport related factor (25%). Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available The last two decades have seen a growing trend towards the research of voting behavior in post-communist countries. Urban sociology theorists state that not only space structures influence political participation, but also space structures are changing under the influence of global, local, and individual factors. The growing role played by information in the globalised world has accelerated the paradigm shift in urban sociology: from central place model (based on urban-rural distinction and on monocentric metropolitan areas to network society (based on space of flows and polycentric metropolitan areas. However, recent studies have mainly focused on countries with solid democracies, rather than on former communist countries. The present study aims to analyze the extent to which a new emerging spatial structure can be envisaged within a metropolitan area of Romania and its consequences for the political dimensions of social capital.The Transilvania University Ethics Commission approved this study (S1 Aprouval. The research is based upon individual and aggregate empirical data, collected from the areas adjacent to the core city in Brașov metropolitan area. Individual data has been collected during October 2012, using the oral survey technique (S1 Survey, based on a standardized questionnaire (stratified simple random sample, N = 600. The National Institute of Statistics and the Electoral Register provided the aggregate data per locality. Unvaried and multivariate analyses (hierarchical regression method were conducted based on these data.Some dimensions of urbanism, identified as predictors of the political dimensions of social capital, suggest that the area under analysis has a predominantly monocentric character, where the rural-urban distinction continues to remain relevant. There are also arguments favoring the dissolution of the rural-urban distinction and the emergence of polycentric spatial structures. The presence of some influences

  13. Tagging in Volunteered Geographic Information: An Analysis of Tagging Practices for Cities and Urban Regions in OpenStreetMap

    Full Text Available In Volunteered Geographic Information (VGI projects, the tagging or annotation of objects is usually performed in a flexible and non-constrained manner. Contributors to a VGI project are normally free to choose whatever tags they feel are appropriate to annotate or describe a particular geographic object or place. In OpenStreetMap (OSM, the Map Features part of the OSM Wiki serves as the de-facto rulebook or ontology for the annotation of features in OSM. Within Map Features, suggestions and guidance on what combinations of tags to use for certain geographic objects are outlined. In this paper, we consider these suggestions and recommendations and analyse the OSM database for 40 cities around the world to ascertain if contributors to OSM in these urban areas are using this guidance in their tagging practices. Overall, we find that compliance with the suggestions and guidance in Map Features is generally average or poor. This leads us to conclude that contributors in these areas do not always tag features with the same level of annotation. Our paper also confirms anecdotal evidence that OSM Map Features is less influential in how OSM contributors tag objects.

  14. Jobs, food, taxis and journals: complexities of implementing Stepping Stones and Creating Futures in urban informal settlements in South Africa.

    This paper seeks to refocus debates on structural interventions away from 'assessing' their effectiveness towards understanding processes around how such interventions are implemented. Implementation Science is focused on understanding potential challenges of translating interventions from highly controlled conditions into 'real life' settings. Using the case study of Stepping Stones and Creating Futures a structural and behavioural intervention to reduce intimate partner violence and HIV risk behaviours amongst young women and men in urban informal settlements, we explore the challenges of implementing such an approach. We move beyond simply describing challenges of implementing, to understand how these challenges had an impact on the safe social space the intervention seeks to create as its underlying theory of change. We identify four major challenges of implementation: taxi fares, food provided during the intervention, young people's ongoing need to work and journals provided during the intervention. We suggest that, in different ways, these factors all impinged on the emergence of a safe social space. Understanding the challenges of implementing the intervention is critical for reflecting on scaling up interventions. Central to this is the need to work with participants to help them negotiate the challenges of participating in interventions.

  15. Using small data to interpret big data: 311 reports as individual contributions to informal social control in urban neighborhoods.

    Informal social control is considered a vital component of the well-being of urban communities. Though some argue that the actions that constitute this social process are often said to reflect territoriality, little else is known about how individuals contribute to it. The current study leverages a database of over 600,000 requests for government services received by the city of Boston, MA's 311 system as a way to answer such questions, focusing particularly on reports of issues in the public space arising from incivilities. In order to establish construct validity for the "big data" of the 311 system, they are combined with the "small data" of a survey of 311 users, permitting the simultaneous analysis of objective reporting behaviors with self-report attitudes. The analysis occurs in two parts. First, reporting of incivilities is distinguished behaviorally from reporting public issues arising from natural deterioration, and people are found to specialize in one or the other. Second, the survey is used to test whether the reports are a reflection of territoriality. Reports of incivilities were unique in their association with a desire to enforce local social norms. They were also associated with a second territorial motivation to benefit the community. Implications for future research are discussed.

  16. Impact of an informal learning science camp on urban, low socioeconomic status middle school students and participating teacher-leaders

    Votaw, Nikki L.

    Studies suggest that students have difficulty connecting science to their own lives (Lee & Fradd, 1998; Aikenhead, 1996). This difficulty results in a decline in students' attitudes toward science, leading to low science achievement. These factors result in fewer students interested in careers related to science, specifically for urban, minority students. The purpose of this study was to examine the impact that a ten day informal learning immersion science camp had on the participants, both urban, low-socioeconomic status middle school students and teacher-leaders. The students were incoming seventh grade students involved in a community-based scholar program designed to recruit and support socioeconomically disadvantaged, academically talented students. The teacher-leaders were professional educators working toward an advanced degree. This ten day camp included seven visits to different sites and complementary classroom-based activities. The purpose of the camp was to immerse the students in informal learning environments that affect their daily lives. Students and teacher-leaders visited facilities that provide public utility services (i.e. power plant, sewage treatment facility, and water company), zoo, large commercial cave system, planetarium, university based electrooptics and nanotechnology center, and forest and arboretum. These site visits were supported by activities that were provided by teacher-leaders. A model used as a framework for studying learning in the context of this ten day camp as Falk and Dierking's (2000) Contextual Model for Learning. This model described three basic intersecting elements that contributed to learning within the given context. The three contexts (personal, sociocultural, and physical) intersect affecting the learning that takes place. A mixed methodology design was employed to determine the impact of the camp on students' content knowledge and attitudes toward science. Qualitative data were collected to determine the impact

  17. Optical interactions of aircraft windscreens and HUDs (Head-Up Displays) producing diplopia

    The Air Force is in the process of evaluating new, wide field of view heads-up displays (WFOV HUDs) capable of presenting an enhanced array of visual imagery to pilots of modern aircraft. The main findings of this study are: (1) observers are relatively intolerant of negative disparity, (2) longer viewing is more likely to lead to a diplopia effect than very short glances, (3) resistance to disparity appears to be an individual trait, and (4) a large proportion of responses involve suppression of the view from one eye. The overall median negative disparity threshold was 1.2 mrad and the overall positive threshold was 2.6 mrad. These values are recommended as the maximum disparities acceptable for wide-field-of-view Canopy-HUD optical systems. Since the values are so small, we further recommend that the canopy and HUD be treated as a system, with technical interaction between the vendors, and between the vendors and the USAF. The disparity values indicate the net difference between both system components, so optimization may be possible by appropriately matching the optics.

    Unscientific utilization of land use and land cover due to rapid growth of urban population deteriorates urban condition. Urban growth, land use change and future urban land demand are key concerns of urban planners. This paper is aimed to model urban land use change essential for sustainable urban development. GI science technology was employed to study the urban change dynamics using Markov Chain and CA-Markov and predicted the magnitude and spatial pattern. It was performed using the probability transition matrix from the Markov chain process, the suitability map of each land use/cover types and the contiguity filter. Suitability maps were generated from the MCE process where weight was derived from the pair wise comparison in the AHP process considering slope, land capability, distance to road, and settlement and water bodies as criterion of factor maps. Thematic land use land cover types of 1999, 2006, and 2013 of Landsat sensors were classified using MLC algorithm. The spatial extent increase from 1999 to 2013 in built up , bush and forest was observed to be 48.30 percent,79.48 percent and 7.79 percent, respectively, while decrease in agriculture and water bodies were 30.26 percent and 28.22 percent. The predicted urban LULC for 2020 and 2027 would provide useful inputs to the decision makers. Built up and bush expansion are explored as the main driving force for loss of agriculture and river areas and has the potential to continue in future also. The abandoned area of river bed has been converted to built- up areas.

    2012-05-01

    Full Text Available Geographic information systems (GIS have been used for many years to integrate social and territorial information in quantitative research, but only recently have they been used in qualitative research. Recent advances have allowed qualitative GIS to be incorporated in the latest versions of computer-aided qualitative data analysis software. This article describes how qualitative GIS integrated in ATLAS.ti were used to perform a recent study of the social production of urban space. It considers the role played by geocoding and georeferencing in this study, and the implications of using qualitative GIS in urban sociology and in sociological research in general.

    2010-03-01

    Full Text Available This cross-sectional study assessed the risk of zinc deficiency in randomly selected children, aged between 7 and 11 years, living in a poor, peri-urban informal settlement in South Africa. Dietary intake of 149 respondents was evaluated by 24-hour recall and quantitative food frequency questionnaires. Anthropometric and biochemical indices of a subset of 113 were determined. Descriptive statistics, analysis of variance and Pearson correlations were computed using the Statistical Package for Social Sciences, version 14.0. Anthropometric data were analysed using the World Health Organization Anthro plus version 1.0.2 statistical software. Dietary data were analysed with FoodFinder® version 3. The mean age of the children was 9.0±1.1 years. Few zinc-rich sources appeared in the diet that was predominantly plant-based. Mean dietary zinc intake was 4.6±2.2 mg/day. The mean value of serum zinc was 66.4±21.5 µg/dL, with 46% of the children having values less than the 70 µg/dL cut-off. The findings indicate a high risk of zinc deficiency and suboptimal zinc status for the majority of this study population of children, possibly as a result of low consumption of food sources with high bioavailability of zinc, which invariably is a direct consequence of poverty and food insecurity.

  7. Negotiating for livelihoods beyond the formal Mzuzu City, Malawi, by the urban poor: Informal settlements as spaces of income generating activities

    Directory of Open Access Journals (Sweden)

    James Gondwe

    2013-02-01

    Full Text Available This article is about how the urban poor in Mzuzu City, Malawi, redefine domestic spaces in their dwellings for supporting their livelihoods. More specifically, it argues that while street vendors negotiate for the use of public spaces within the ‘formal city’ for income generating activities, the urban poor in informal settlements negotiate for use of spaces in their dwellings for generating cash income. Spaces for income generating activities are as contested as spaces for vending in the ‘formal city.’ In this context, the urban poor become creative enough to overcome equally demanding domestic functions of their dwellings. Furthermore, power imbalance is also epitomised in home based enterprises where tenants have to negotiate with their landlords for use of dwellings for generating income and accumulation of assets. However, it is not only physical spaces whose use for income generating activities is negotiable. Rather gender relations in some households are also negotiated for and contested spaces. Despite their visibility in home based enterprises, women appear to lack control over resources which they help to generate.  The paper further argues that labeling livelihood strategies of the urban poor as ‘marginal,’ ‘vulnerable,’ and ‘survival enterprises’ is problematic because the urban poor are not a homogeneous group. Since their perceptions, motivations, skills and knowledge differ; their livelihoods outcomes are also likely to be different. Thus, the accumulation of income and assets should not be the only variables used for measuring the success or failure of home based enterprises because their outcomes are also heavily embedded in informal social security networks.

    .The integrated multimodal network model combines the various mobility infrastructure networks and the buildings’ land use to create a detailed description of the region, using open spatial data and open source Geographic Information Systems (GIS technologies. The network model’s spatial analysis covers local urban form indicators, such as street layout, network density and land use mix, as well as regional indicators of multimodal accessibility and network configuration (its structure, to give a holistic profile of urban areas across modes and scales of travel.The analysis results go through exploratory data mining and classification procedures to identify urban form typologies of urban areas. It is shown that there is a relation between this ‘urban modality’ of urban areas and the travel patterns of their residents, measured as a set of sustainable mobility indicators related to mode share and distance travelled. For this reason, ‘urban modality’ offers the possibility for ex-ante evaluation of sustainable mobility potential of planned urban areas. Furthermore, when combined with the socio-economic profile of the resident population, ‘urban modality’ defines a context for the ex-post evaluation of sustainable mobility performance of existing urban areas.The evaluation of suburban areas together with the more central historical urban areas gives invariably a high score in sustainable travel to the central areas, and rates the suburban areas negatively. On the other hand, the evaluation of sustainable mobility performance in the context of suburban areas of the same type allows the finer distinction of underperformers that have scope for improvement, and overachievers that provide examples of (relative success. This contextual evaluation can become a decision support instrument for “hard” and “soft” planning measures involving sustainable mobility targets.Applying this method to the set of VINEX neighbourhoods of the Randstad leads to the conclusion that

But these migrant workers are hard to integrate into the urban society well. The social integration is not only a social economic problem, but also an information matter. The investigation into 566 migrant workers in Tianjin and Chongqing shows that migrant workers are information disadvantage groups, they are lack of modern information communication tools and abilities, the information default is the greatest obstacle for migrant workers when they integrate into the urban. It also shows that modern information communication tools and channels have the significant positive influence on the social integration of migrant workers. Therefore, public libraries should carry out the information assistance for migrant workers from services, the information retrieval training and providing public information infrastructures, in order to promote the social integration of migrant workers.

    2017-06-01

    Full Text Available Urban pattern is the result of a dynamic transformation process, which can follow two different trajectories: planned interventions generally produces clear geometrical patterns in large areas, however, unplanned transformation process needs more time and has relatively smaller and partial effects on the urban pattern but creates more complex urban patterns. Highly complex spatial structure of urban pattern governed by local and global forces should be analyzed via advanced methods that corresponds the complexity of the pattern. Analyses of the dynamic structure of the multidimensional urban system shows the necessity of using advanced methods and several parameters together. The aim of this paper is developing a new method to analyze and represent highly complex urban pattern via evaluating geometrical, topological, and mathematical parameters to evaluate essential characteristics of cities. Physical space is analyzed by ‘geometrical parameters’, ‘topological parameters’, ‘parameters related to use and perception’ and ‘parameters related to complexity’. Calculation results gives two main information about urban structure: Firstly, values gives information about spatial characteristics and diversity of urban pattern. Secondly, the spatial distribution map of changing urban pattern reflects the unique structure of settlements, which resembles DNA of living creatures. In this paper, Istanbul was selected as case study area because of the rich historical background and dynamic urban growth process resulting various types of settlements including historical settlements, old villages, unplanned development, squatter areas and gated communities with different densities. As the proposed model shows essential morphological characteristics of urban pattern as a morphological DNA, outputs of this model has a potential to be used in different areas such as comparative analysis of geometrically different cities, analyzing irregularities in

    2017-03-01

    Full Text Available Urbanization is one of the processes that determine the development of a country or a region, but it has both advantages and side effects. Some of its aspects may lead to unsustainable growth and dispersion of built–up area. The main causes of this process are increases in costs of transportation, infrastructure and nature conservation. There is a threat of uncontrolled spread of development as a result of urbanization processes, particularly in suburban municipalities. It has been requested by many researches that authorities put more interest in avoiding dispersed suburbanization, but they still are looking for better solutions, tools and procedures to solve this problem.

    2016-08-04

    This article explores how women front-line workers engage with domestic and gender-based violence in the urban informal settlements of Dharavi in Mumbai, India. We conducted in-depth interviews with 13 voluntary front-line workers, along with ethnographic fieldwork in Dharavi, as a part of a pilot study. Our findings contribute to literature on context-specific approaches to understanding gender-based violence and "models" to prevent domestic violence in urban micro-spaces. Furthermore, we also discuss notions of "change" (badlaav) that the front-line workers experience. Finally, this article presents implications for socially engaged ethnographic research, as well as contextual and grounded insights on ways to reduce gender-based and domestic violence. © The Author(s) 2016.

This simple and concise statement comes out from a brief analysis of both the latest interests of different scholars and the discourses of urban, regional, and governmental actors. The change we are talking about refers to a slight interest drop in environmental issues and an ever-increasing attention paid to the economic and social aspects of urban life. The conceptual shift from sustainable development to smart growth is a good example, and the fact that the recent European Union papers (EU 2020 strategy, EU Cohesion Policy 2014-2020 have adopted it ensures its liability. Coming to urban planning, which is primarily conceived as sets of regulatory measures, one can notice that in order to achieve the latest standards it has to develop and implement new methods and instruments which will eventually lead to smart, sustainable and inclusive growth. Knowing that urban plans look to specific urban issues as zoning, layout and design, which are usually regulated by legally approved national guidelines, this new tasks fall into the charge of informal planning. In Romania, informal planning refers to local development strategies, local action plans as well as the Local Agenda 21, which was implemented throughout the world. Admitting that municipalities worldwide are in a sharp competition for inhabitants, investors and capital (from trade, tourism, exhibitions, etc., we realize that small and medium-sized towns have to ensure that all of their valuable characteristics are as visible and as marketable as possible. In order to do this, they have to enhance their attractiveness through different actions, using different methods and instruments. The present paper highlights the ways that local actors in four small cities in Bihor County, Romania are trying to market their municipalities. The chosen cities organically fit into one of the most representative mental space in Romania, the

    2010-12-01

    In Kampala, Uganda, studies have shown a significant incidence of human brucellosis. A stochastic risk assessment involving two field surveys (cattle farms and milk shops) and a medical record survey was conducted to assess the risk of human brucellosis infection through consumption of informally marketed raw milk potentially infected with Brucella abortus in Kampala and to identify the best control options. In the cattle farm survey, sera of 425 cows in 177 herds in the Kampala economic zone were sampled and tested for brucellosis using a competitive enzyme-linked immunosorbent assay (CELISA). Farmers were interviewed for dairy information. In the milk shop surveys, 135 milk sellers in the urban areas were interviewed and 117 milk samples were collected and tested using an indirect enzyme-linked immunosorbent assay (IELISA). A medical record survey was conducted in Mulago National Referral Hospital for serological test results. A risk model was developed synthesizing data from these three surveys. Possible control options were prepared based on the model and the reduction of risk was simulated for each scenario. Overall, 12.6% (6.8-18.9: 90%CI) of informally marketed milk in urban Kampala was contaminated with B.abortus at purchase and the annual incidence rate was estimated to be 5.8 (90% CI: 5.3-6.2) per 10,000 people. The best control option would be the construction of a milk boiling centre either in Mbarara, the largest source of milk, or in peri-urban Kampala and to ensure that milk traders always sell milk to the boiling centre; 90% success in enforcing these two options would reduce risk by 47.4% (21.6-70.1: 90%CI) and 82.0% (71.0-89.0: 90%CI), respectively. This study quantifies the risk of human brucellosis infection through informally marketed milk and estimates the incidence rate in Kampala for the first time; risk-based mitigation strategies are outlined to assist in developing policy.

    Full Text Available With the prevalence of smartphones, new ways of engaging citizens and stakeholders in urban planning and governance are emerging. The technologies in smartphones allow citizens to act as sensors of their environment, producing and sharing rich spatial data useful for new types of collaborative governance set-ups. Data derived from Volunteered Geographic Information (VGI can support accessible, transparent, democratic, inclusive, and locally-based governance situations of interest to planners, citizens, politicians, and scientists. However, there are still uncertainties about how to actually conduct this in practice. This study explores how social media VGI can be used to document spatial tendencies regarding citizens’ uses and perceptions of urban nature with relevance for urban green space governance. Via the hashtag #sharingcph, created by the City of Copenhagen in 2014, VGI data consisting of geo-referenced images were collected from Instagram, categorised according to their content and analysed according to their spatial distribution patterns. The results show specific spatial distributions of the images and main hotspots. Many possibilities and much potential of using VGI for generating, sharing, visualising and communicating knowledge about citizens’ spatial uses and preferences exist, but as a tool to support scientific and democratic interaction, VGI data is challenged by practical, technical and ethical concerns. More research is needed in order to better understand the usefulness and application of this rich data source to governance.

    Safe water storage and hand hygiene have been shown to reduce fecal contamination and improve health in experimental settings; however, triggering and sustaining such behaviors is challenging. This study investigates the extent to which personalized information about Escherichia coli contamination of stored water and hands influenced knowledge, reported behaviors, and subsequent contamination levels among 334 households with less than 5-year-old children in peri-urban Dar es Salaam, Tanzania. One-quarter of the study participants received information about strategies to reduce risk of water- and sanitation-related illness. Respondents in another three study cohorts received this same information, along with their household's water and/or hand-rinse test results. Findings from this study suggest that additional work is needed to elucidate the conditions under which such testing represents a cost-effective strategy to motivate improved household water management and hand hygiene.

  7. HuD interacts with Bdnf mRNA and is essential for activity-induced BDNF synthesis in dendrites.

    Directory of Open Access Journals (Sweden)

    Filip Vanevski

    Full Text Available Highly specific activity-dependent neuronal responses are necessary for modulating synapses to facilitate learning and memory. We present evidence linking a number of important processes involved in regulating synaptic plasticity, suggesting a mechanistic pathway whereby activity-dependent signaling, likely through protein kinase C (PKC-mediated phosphorylation of HuD, can relieve basal repression of Bdnf mRNA translation in dendrites, allowing for increased TrkB signaling and synaptic remodeling. We demonstrate that the neuronal ELAV family of RNA binding proteins associates in vivo with several Bdnf mRNA isoforms present in the adult brain in an activity-dependent manner, and that one member, HuD, interacts directly with sequences in the long Bdnf 3' untranslated region (3'UTR and co-localizes with Bdnf mRNA in dendrites of hippocampal neurons. Activation of PKC leads to increased dendritic translation of mRNAs containing the long Bdnf 3'UTR, a process that is dependent on the presence of HuD and its phosphorylation at threonine residues 149 and/or 165. Thus, we found a direct effect of HuD on regulating translation of dendritic Bdnf mRNAs to mediate local and activity-dependent increases in dendritic BDNF synthesis.

    Full Text Available Abstract Background Obtaining new pharmaceutical materials with enhanced properties by using natural compounds and environment-friendly methods is a continuous goal for scientists. Ficaria verna Huds. is a widespread perennial plant with applications in the treat of haemorrhoids and to cure piles; it has also anti-inflammatory, astringent, and antibiotic properties. The goal of the present study is the obtaining and characterization of new F. verna extract/β-cyclodextrin complexes by using only natural compounds, solvents, and environment-friendly methods in order to increase the quality and acceptability versus toxicity indicator. Thus, the flavonoid content (as quercetin of Ficaria verna Huds. flowers and leaves from the West side of Romania was determined and correlated with their antioxidant activity. Further, the possibility of obtaining β-cyclodextrin supramolecular systems was studied. Results F. verna flowers and leaves extracts were obtained by semi-continuous solid-liquid extraction. The raw concentrated extract was spectrophotometrically analyzed in order to quantify the flavonoids from plant parts and to evaluate the antioxidant activity of these extracts. The F. verna extracts were used for obtaining β-cyclodextrin complexes; these were analyzed by scanning electron microscopy and Karl Fischer water titration; spectrophotometry was used in order to quantifying the flavonoids and evaluates the antioxidant activity. A higher concentration of flavonoids of 0.5% was determined in complexes obtained by crystallisation method, while only a half of this value was calculated for kneading method. The antioxidant activity of these complexes was correlated with the flavonoid content and this parameter reveals possible controlled release properties. Conclusions The flavonoid content of F. verna Huds. from the West side of Romania (Banat county is approximately the same in flowers and leaves, being situated at a medium value among other

    The following report is strictly connected to studies for introducing certain actions useful to effort the problem of urban traffic pollution. Technologies are today available to reduce traffic pollution and it is possible to verify effectiveness during the implementation. On the other hand it is not always possible to verify effectiveness of these measures on the citizen customs and quality of life. Frequently policies aiming to limit environmental risk are viewed by citizens as an insupportable coercion. In the case of urban traffic it is particularly true because the measures in this field are limited to a certain numbers of prohibitions limiting the moving freedom of citizens inside urban areas. This research, realised via a questionnaire on citizens representative of two roman districts, analyses the social acceptability degree of actions for reducing atmospheric pollution produced by automobile traffic in the city of Rome. [Italian] Il lavoro presentato di seguito si inserisce in un filone di studi che tendono a individuare quelle azioni capaci di sciogliere il nodo ormai cruciale dell'inquinamento da traffico nelle aree urbane. Azioni efficaci ne sono state individuate numerose ma, mentre per quanto riguarda le misure tecnologiche l'efficacia intrinseca della misura viene verificata nell'applicazione, non sempre si puo' dire la stessa cosa per quanto riguarda le misure che incidono sulle abitudini di vita dei cittadini. Sempre piu' spesso le politiche tese a limitare i danni ambientali sono vissute dal cittadino come una insopportabile coercizione. Nel caso del traffico urbano cio' e' particolarmente vero proprio perche' le misure di questo settore si limitano spesso a una serie di divieti che oggettivamente limitano la liberta' di movimento del cittadino. I blocchi del traffico, le zone blu, sono gli esempi piu' lampanti di questo tipo di limitazione. Questa ricerca sul campo, svolta tramite questionario e

  12. Estimating farm and landscape water use at the rural-urban interface using remote sensing and geographic information systems

    Farag, Fayek Amin

    This study investigated the urban landscape water conservation potential distribution among residential and commercial water users. It also presented the potential of agricultural water conservation and then discussed water conversion from agricultural to urban use. Using multispectral airborne digital images analyzed within a GIS environment gave solid estimates of actual landscaped area and consequently the estimates of water demand. In the present study for the city of Layton, it has been shown that most of the subdivisions use more water than needed for landscape irrigation. The CII (commercial-institutional-industrial) users had the greatest potential for water savings, particularly those with smaller landscapes. The potential for greatest water savings is from mid to late summer when run times for automated systems are not being reduced as ET declines. The overall picture that emerges is that older landscapes without automated irrigation systems are less likely to be wasting water. The landscapes most likely to waste irrigation water are those that have automated systems not because of the automated system itself but because of the inefficiency in operating the system. For the discussed five seasons (1997--2001), the study has also illustrated that there are some subdivisions that have excessive excess water (use a lot more water than needed for landscape irrigation), while their percentages of landscape area are low. On the other hand, there are some subdivisions that consume smaller amounts of excess water, while their percentage of landscape area is higher. This means that there are other dominant influencing factors such as the irrigation system used (automatic sprinkler or old manual system), income, education, retired heads, and the number of people living in the house. The research has also shown that there are houses in each subdivision that need to be identified for education on water conservation as they consume more than 70% of the total excess

    More than 35% of American adults are obese. For African American and Hispanic adults, as well as individuals residing in poorer or more racially segregated urban neighborhoods, the likelihood of obesity is even higher. Information and communication technologies (ICTs) may substitute for or complement community-based resources for weight management. However, little is currently known about health-specific ICT use among urban-dwelling people with obesity. We describe health-specific ICT use and its relationship to measured obesity among adults in high-poverty urban communities. Using data collected between November 2012 and July 2013 from a population-based probability sample of urban-dwelling African American and Hispanic adults residing on the South Side of Chicago, we described patterns of ICT use in relation to measured obesity defined by a body mass index (BMI) of ≥30 kg/m(2). Among those with BMI≥30 kg/m(2), we also assessed the association between health-specific ICT use and diagnosed versus undiagnosed obesity as well as differences in health-specific ICT use by self-reported comorbidities, including diabetes and hypertension. The survey response rate was 44.6% (267 completed surveys/598.4 eligible or likely eligible individuals); 53.2% were African American and 34.6% were Hispanic. More than 35% of the population reported an annual income of less than US $25,000. The population prevalence of measured obesity was 50.2%. People with measured obesity (BMI≥30 kg/m(2)) were more likely to report both general (81.5% vs 67.0%, P=.04) and health-specific (61.1% vs 41.2%, P=.01) ICT use. In contrast, among those with measured obesity, being told of this diagnosis by a physician was not associated with increased health-specific ICT use. People with measured obesity alone had higher rates of health-specific use than those with comorbid hypertension and/or diabetes diagnoses (77.1% vs 60.7% vs 47.4%, P=.04). In conclusion, ICT-based health resources may be

    The small sample with incomplete information was employed to assess the urban regional work safety risk. Based on the methodology of information diffusion which could fuzzify single sample point, the mapping relationship between observation sample and risk probability distribution was studied by properly expanding the incomplete information with the diffusion function applied the principles of information diffusion , and a work safety risk calculation model of urban region based on the information diffusion was established. In addition, the work safety risk of Xinbei district in a city was taken as an example. Annual fatalities of construction site, fire, industrial accidents and mortality per 100 million yuan GDP from 2005 to 2010 were picked up as the observation samples of work safety risk in this region. Then their risks were calculated respectively using the established risk calculation model. The analysis results show that the calculation results are in substantial consistency with the actualities, which favors the work safety risk assessment of urban region from a macroscopic perspective, and can provide technology reference for administration of work safety.%应用信息扩散原理,通过扩散函数对不完备信息进行适当的信息膨胀,建立观测样本和风险概率分布的映射关系,构建了基于信息扩散的城市区域安全生产风险计算模型.并以某市新北区的安全生产风险作为研究对象,选取该区域2005-2010年各年度建筑施工事故、火灾事故、工矿商贸事故的死亡人数和地区亿元GDP死亡率作为该区域安全生产风险的观测样本,运用构建的风险计算模型,得出建筑施工、火灾、工矿商贸死亡事故风险估计和地区亿元GDP死亡率风险估计.由分析可知,计算结果与实际情况基本吻合,这将有助于从宏观角度对城市区域的安全生产风险进行估计,可为安全生产监管提供有益的参考.

    Although triglyceride (TG) accumulation in the pancreas leads to β-cell dysfunction and raises the chance to develop metabolic disorders such as type 2 diabetes (T2DM), the molecular mechanisms whereby intracellular TG levels are regulated in pancreatic β cells have not been fully elucidated. Here, we present evidence that the RNA-binding protein HuD regulates TG production in pancreatic β cells. Mouse insulinoma βTC6 cells stably expressing a small hairpin RNA targeting HuD (shHuD) (βTC6-shHuD) contained higher TG levels compared to control cells. Moreover, downregulation of HuD resulted in a decrease in insulin-induced gene 1 (INSIG1) levels but not in the levels of sterol regulatory element-binding protein 1c (SREBP1c), a key transcription factor for lipid production. We identified Insig1 mRNA as a direct target of HuD by using ribonucleoprotein immunoprecipitation (RIP) and biotin pulldown analyses. By associating with the 3'-untranslated region (3'UTR) of Insig1 mRNA, HuD promoted INSIG1 translation; accordingly, HuD downregulation reduced while ectopic HuD expression increased INSIG1 levels. We further observed that HuD downregulation facilitated the nuclear localization of SREBP1c, thereby increasing the transcriptional activity of SREBP1c and the expression of target genes involved in lipogenesis; likewise, we observed lower INSIG1 levels in the pancreatic islets of HuD-null mice. Taken together, our results indicate that HuD functions as a novel repressor of lipid synthesis in pancreatic β cells.

    2015-02-01

    A high brightness Head-Up Display (HUD) module was demonstrated with a fast, dual-axis MEMS mirror that displays vector images and text, utilizing its ~8kHz bandwidth on both axes. Two methodologies were evaluated: in one, the mirror steers a laser at wide angles of phone applications is demonstrated, utilizing the mobile device both for content generation based on various messages or data, and for content streaming to the MEMS controller via Bluetooth interface. The display unit is highly resistant to vibrations and shock, and requires only ~1.5W to operate, even with content readable in sunlit outdoor conditions. The low power requirement is in part due to a vector graphics approach, allowing the efficient use of laser power, and also due to the use of a single, relatively high efficiency laser and simple optics.

    Full Text Available Entomopathogenic fungi are the largest group of microorganisms existing in the soil environment. Occurrence and pathogenicity of entomopathogenic fungi in soil is dependent on many factors affecting the soil environment. The aim of this study was to compare the species composition and the intensity of the occurrence of entomopathogenic fungi in soils from monoculture crops of Festuca pratensis Huds. The study material consisted of soil samples taken from the experiment conducted in two experimental stations of the Research Centre for Cultivars Study. The insecticides fungi were isolated from soil using a method of the selective substrate. Three species of entomopathogenic fungi Beauveria bassiana, Isaria fumosorosea and Metarhizium anisopliae were isolated from the study soils using the selective medium.

    Tekeľová, Daniela; Bittner Fialová, Silvia; Tóth, Jaroslav; Czigle, Szilvia

    Lamiaceae plants mostly accumulate active ingredients in their leaves. The subfamily Nepetoideae, including the genus Mentha L., is characterized by the presence of essential oil and antioxidant phenolics, chiefly hydroxycinnamic acids with predominance of rosmarinic acid, and flavonoids. Mentha × piperita and M. spicata are the most broadly used mints in both medicine and industry, while M. x villosa is less known in our country. Herbal drugs in the form of leaves are usually analysed unpartitioned, while single leaves insertions have only been studied occasionally. Therefore, the aim of this work was the quantification of the active compounds content in the leaves pairs of Mentha × villosa Huds. cv. Snežná, using pharmacopoeial methods: total hydroxycinnamic derivatives expressed as rosmarinic acid (THD) and luteolin-type flavonoids. THD content ranged from 6.7% to 9.4% in the leaves pairs water extracts, and from 6.6% to 14.0% in methanol extracts. Flavonoids contents, expressed as luteolin-7-O-glucoside, ranged from 4.0% to 8.8% in water extracts, and from 4.0% to 10.5% in methanol extracts. Antioxidant activity (DPPH) expressed as SC50 ranged from 10.2 to 16.9 μg.ml-1 (drug dry weight) in water extracts, and from 10.7 to 21.6 μg.ml-1 in methanol extracts. The highest content of phenolic compounds as well as the highest antioxidant activity were found to be in the top sheet, while the lowest content of phenolic compounds and lowest antioxidant activity were detected in the leaves of the middle stem part.Key words: Mentha × villosa Huds cv. Snežná hydroxycinnamic derivatives rosmarinic acid luteolin-7-O-glucoside DPPH.

  3. Integrating Sustainability Science with the Sciences of Human Well-being to Inform Design and Planning in an Urbanizing World

    A sustainable human future requires both healthy ecosystems and communities in which people thrive, with opportunities for health, well-being, happiness, economic prosperity, and equity. To make progress towards this goal, two largely disparate communities of scholars and practitioners must come together: sustainability science needs to be integrated with the sciences of human health and well-being. The opportunity for such integration is particularly ripe for urbanizing regions which not only dominate energy and resource use but also increasingly represent the human habitat. We present a conceptual framework that integrates sustainability science with the sciences of human health and well-being to explicitly articulate testable hypotheses on the relationships between humans and their habitat. We are interested in human behaviors and metrics of health and well-being in relationship to the characteristics of the built environment at various scales from buildings to metro regions. Focusing on the U.S. Pacific Northwest (PNW) as a testbed, we are building on our current empirical studies on urban sprawl and ecosystem function including biodiversity, air quality, hydrological, biogeochemical, and human health to develop formal hypotheses on how alternative urban design and development patterns may influence health outcomes and well-being. The PNW is an ideal setting for this work because of the connected metropolitan areas within a region characterized by a spectacular diversity of aquatic and terrestrial ecosystems and deeply held cultural and political aspirations towards sustainability. The framework also highlights opportunities for translation of knowledge to practice in the design and planning of built environments. For example, understanding these associations is critical to assessing tradeoffs in design and planning strategies and exploring potential synergies that optimize both sustainability and human well-being. In complex systems such as cities, managers

  4. Integrating Urban Heat Assessment in Urban Plans

    Full Text Available The world is increasingly concerned with sustainability issues. Climate change is not the least of these concerns. The complexity of these issues is such that data and information management form an important means of making the right decisions. Nowadays, however, the sheer quantity of data is overwhelming; large quantities of data demand means of representation that are comprehensible and effective. The above dilemma poses questions as to how one incorporates unknown climatologic parameters, such as urban heat, in future urban planning processes, and how one ensures the proposals are specific enough to actually adapt cities to climate change and flexible enough to ensure the proposed measures are combinable and compatible with other urban planning priorities. Conventional urban planning processes and mapping strategies are not adapted to this new environmental, technological and social context. In order come up with more appropriate urban planning strategies, in its first section this paper analyzes the role of the urban planner, reviews the wide variety of parameters that are starting to be integrated into the urban planners practice, and considers the parameters (mainly land surface temperature, albedo, vegetation, and imperviousness and tools needed for the assessment of the UHI (satellite imagery and GIS. The second part of the study analyzes the potential of four catalyzing mapping categories to integrate urban heat into spatial planning processes: drift, layering, game-board, and rhizome.

    Water Sensitive Urban Design (WSUD) poses new challenges for decision makers compared with traditional stormwater management, e.g., because WSUD offers a larger selection of measures and because many measures are multifunctional. These challenges have motivated the development of many decision...... support tools. This review shows that the tools differ in terms of the types of questions they can assist in answering. We identified three main groups: “How Much”-tools, “Where”-tools and “Which”-tools. The “How Much”-tools can further be grouped into tools quantifying hydraulic impacts, hydrologic...... impacts, water quality impacts, non-flow-related impacts and economic impacts. Additionally, the tools differ in terms of how many aspects of water they address, from those focused only on bio-physical aspects to those attempting to find the best WSUD based on multiple criteria. Finally, we suggest...

    To compare sociodemographic and motivational factors for healthcare use and identify desirable health-promoting resources among groups in a low socioeconomic status (SES) community in Chicago, IL. Disparities in health services and outcomes are well established in low SES urban neighborhoods in the United States and many factors beyond service availability and quality impact community health. Yet there is no clear process for engaging communities in building resources to improve population-level health in such locales. A hospital building project led to a partnership of public health researchers, architects, and planners who conducted community-engaged research. We collected resident data and compared factors for healthcare use and choice and likelihood of engaging new health-promoting services. Neighborhood areas were strongly associated with ethnic groupings, and there were differences between groups in healthcare choice and service needs, such as, proximity to home was more important to Latinos than African Americans in choice of healthcare facility ( p adj = .001). Latinos expressed higher likelihood to use a fitness facility ( p adj = .001). Despite differences in vehicle ownership, >75% of all respondents indicated that nearby public transportation was important in choosing healthcare. Knowledge of community needs and heterogeneity is essential to decision makers of facility and community development plans. Partnerships between public health, urban planning, architecture, and local constituents should be cultivated toward focus on reducing health disparities. Further work to integrate community perspectives through the planning and design process and to evaluate the long-term impact of such efforts is needed. © The Author(s) 2015.

    Full Text Available People living in poverty make up nearly half of the global population and a large proportion of these individuals inhabit cities, living in informal settlements. However, only limited research on in-home environmental exposures and the associated health effects in these communities is available. This research investigates the home environment in unplanned settlements of a rapidly growing city on the U.S.-México border and its impact on the health of households with children under 12 years of age. A cross-sectional design was used to assess household exposures and health outcomes at the household level. A total of 202 households were selected from two informal settlements in the peri-urban region of Ciudad Juárez, México. The following variables were significantly associated with the report of at least one household member experiencing a health outcome in a two week period. Allergies were positively associated with insecticide use inside the home (adjusted Relative Odds (RO, 2.71; 95% confidence interval (CI, 1.2-6.3. Respiratory problems were associated with households using a wood burning stove vs. a gas stove (adjusted RO, 5.64; 95% CI, 1.1-27.9. Diarrhea was negatively associated with presence of a flush toilet in the home (adjusted RO, 0.22; 95% CI,0.1-0.6. Finally, eye irritations were positively associated with indoor tobacco smoke (adjusted RO, 2.23; 95% CI, 1.1-4.5. This research highlights exposures associated with poor living conditions in informal settlements and their associations with detrimental effects on health. More efforts should be made to understand the dynamics of poor urban environments including the health effects of exposures linked with poor housing conditions.

    This paper explores forecasting short-term urban water demand (UWD) (using only historical records) through a variety of machine learning techniques coupled with a novel input variable selection (IVS) procedure. The proposed IVS technique termed, bootstrap rank-ordered conditional mutual information for real-valued signals (brCMIr), is multivariate, nonlinear, nonparametric, and probabilistic. The brCMIr method was tested in a case study using water demand time series for two urban water supply system pressure zones in Ottawa, Canada to select the most important historical records for use with each machine learning technique in order to generate forecasts of average and peak UWD for the respective pressure zones at lead times of 1, 3, and 7 days ahead. All lead time forecasts are computed using Artificial Neural Networks (ANN) as the base model, and are compared with Least Squares Support Vector Regression (LSSVR), as well as a novel machine learning method for UWD forecasting: the Extreme Learning Machine (ELM). Results from one-way analysis of variance (ANOVA) and Tukey Honesty Significance Difference (HSD) tests indicate that the LSSVR and ELM models are the best machine learning techniques to pair with brCMIr. However, ELM has significant computational advantages over LSSVR (and ANN) and provides a new and promising technique to explore in UWD forecasting.

    2017-01-01

    The development of a city could create adverse effects, such as increase in air pollutant, and decrease in amenity. One of the ways to overcome these adverse effects is developing urban forest. For maximizing the function of urban forest, the appropriate types of urban forest to be developed, should be determined first. The aims of this study were to determine the appropriate types of urban forest and to identify the shape of urban forest in Tangerang Selatan City by using GIS and remote sensing. Urban forest shape was identified on the basis of shape and distribution of land unit. The steps of the study comprised data collection, map preparation and data analysis. Landsat 8 satellite imagery was interpreted for land use/cover classification. Scoring based on air temperature, land slope, and soil types was used to determine priority of the urban forest locations. Besides that, land use planning was considered to determine the appropriate urban forest type. The results of the study show that the appropriate urban forest types are residential area urban forest, industry urban forest, and recreation urban forest. On the other hand, the appropriate urban forest shapes are strip, scattered, and clustered pattern.

    2013-08-01

    Full Text Available Background: Well-working health information systems are considered vital with the quality of health data ranked of highest importance for decision making at patient care and policy levels. In particular, health facilities play an important role, since they are not only the entry point for the national health information system but also use health data (and primarily for patient care. Design: A multiple case study was carried out between March and August 2012 at the antenatal care (ANC clinics of two private and one public Kenyan hospital to describe clinical information systems and assess the quality of information. The following methods were developed and employed in an iterative process: workplace walkthroughs, structured and in-depth interviews with staff members, and a quantitative assessment of data quality (completeness and accurate transmission of clinical information and reports in ANC. Views of staff and management on the quality of employed information systems, data quality, and influencing factors were captured qualitatively. Results: Staff rated the quality of information higher in the private hospitals employing computers than in the public hospital which relies on paper forms. Several potential threats to data quality were reported. Limitations in data quality were common at all study sites including wrong test results, missing registers, and inconsistencies in reports. Feedback was seldom on content or quality of reports and usage of data beyond individual patient care was low. Conclusions: We argue that the limited data quality has to be seen in the broader perspective of the information systems in which it is produced and used. The combination of different methods has proven to be useful for this. To improve the effectiveness and capabilities of these systems, combined measures are needed which include technical and organizational aspects (e.g. regular feedback to health workers and individual skills and motivation.

    This paper explores a consequence of metropolitan and development centers policy to the development progress of coastal territories by analyzing municipal website base on urban communication functions of communicative city concept. In terms of coastal territories as a part of development center, efforts have to be made in enhancing the role and function of municipal website to show their development progress. Perceptual analysis is taken as a method to measure their position, especially kabupaten/kota as coastal territories in regional context (West Java Province). The results indicate that the availability of public information in coastal territories cities lower than other cities in metropolitan area. Innovation in specifying coastal features has to be promoted in illustrating development progress of coastal territories as a part of development centers in West Java Province.

    2013-12-01

    Full Text Available Within recent years, there has been a renewed focus on sound in urban environments. From sound installations in public space to sound festivals in alternative settings, we find a common interest in sound art relating to the urban environment. Artworks or interventions presented in such contexts share the characteristics of site specificity. However, this article will consider the artwork in a broader context by re-examining how sound installations relate to the urban environment. For that purpose, this article brings together ecology terms from acoustic ecology of the sound theories of the 1970s while developing them into recent definitions of ecology in urban studies. Finally, we unfold our framing of urban sound ecologies with three case analyses: a sound intervention in Berlin, a symphony for wind instruments in Copenhagen and a video walk in a former railway station in Kassel. The article concludes that the ways in which recent sound installations work with urban ecologies vary. While two of the examples blend into the urban environment, the other transfers the concert format and its mode of listening to urban space. Last, and in accordance with recent soundscape research, we point to how artists working with new information and media technologies create inventive ways of inserting sound and image into urban environments.

    Okurut, Kenan; Kulabako, Robinah Nakawunde; Chenoweth, Jonathan; Charles, Katrina

    2015-01-01

    Sanitation improvement is crucial in saving lives that are lost due to water contamination. Progress towards achieving full sanitation coverage is still slow in low-income informal settlements in most developing countries. Furthermore, resources are being wasted on installing facilities that are later misused or never used because they do not meet the local demand. Understanding demand for improved sanitation in the local context is critical if facilities are to be continually used. Various approaches that attempt to change peoples' behaviours or create demand have been reviewed to identify what they are designed to address. A multi-disciplinary research team using mixed methods is re-emphasised as a comprehensive approach for assessing demand for improved sanitation in low-income informal settlements, where the sanitation situation is more challenging than in other areas. Further research involving a multi-disciplinary research team and use of mixed methods to assess sanitation demand in informal settlements is needed.

  8. Financing and budgetary impact of landslide losses for highways and urban infrastructures in NW Germany - an economic analysis using landslide database information and cost survey data

    Maurischat, Philipp; Klose, Martin

    2014-05-01

    Recent studies show that landslides cause even in low mountain areas of Central and Western Europe millions of dollars in annual losses (Klose et al., 2012; Vranken et al., 2013). The objective of this study has therefore been to model landslide disaster financing and to assess budgetary impacts of landslide losses for highways and urban infrastructures in the Lower Saxon Uplands, NW Germany. The present contribution includes two case studies on the financial burden of landslides for public budgets using the examples of the Lower Saxony Department of Transportation and the city of Hann. Münden. The basis of this research is a regional subset of a landslide database for the Federal Republic of Germany. Using a toolset for landslide cost modeling based on landslide databases (Klose et al., 2013), the direct costs of more than 30 landslide damage events to highways in a local case study area were determined. The annual average landslide maintenance, repair, and mitigation costs for highways in this case study area are estimated at 0.76 million between 1980 and 2010. Alternatively, a cost survey based on expert interviews has been conducted to collect landslide loss data for urban infrastructures. This cost survey for the city of Hann. Münden shows annual landslide losses of up to 3.4 million during the previous 10 years. Further expert interviews at city and highway agency level were focused on identifying procedure, resources, and limits of financing landslide damage costs. The information on landslide disaster financing and cost survey data on annual maintenance and construction budgets for highways, city sewer lines, and urban roads were used to evaluate the fiscal significance of estimated landslide losses. The results of this economic impact assessment prove variable financial burdens of analyzed public budgets. Thus, in costly years with landslide losses of more than 7 million, the Lower Saxony Department of Transportation is required to shift up to 19% of its

    Grace, Shamarion Gladys

    This is a three-article five chapter doctoral dissertation. The overall purpose of this three-pronged study is to engage a middle school science teacher and students in formal-informal science education within the context of a science standards-based curriculum and Urban Science Center. The goals of the study were: (1) to characterize the conversations of formal and informal science educators as they attempted to implement a standards-based curriculum augmented with science center exhibits; (2) to study the classroom discourse between the teacher and students that foster the development of common knowledge in science and student understanding of the concept of energy before observing science center exhibits on energy; (3) to investigate whether or not a standards-driven, project-based Investigating and Questioning our World through Science and Technology (IQWST) curriculum unit on forms and transformation of energy augmented with science center exhibits had a significant effect on urban African-American seventh grade students' achievement and learning. Overall, the study consisted of a mixed-method approach. Article one consists of a case study featuring semi-structured interviews and field notes. Article two consists of documenting and interpreting teacher-students' classroom discourse. Article three consists of qualitative methods (classroom discussion, focus group interviews, student video creation) and quantitative methods (multiple choice and open-ended questions). Oral discourses in all three studies were audio-recorded and transcribed verbatim. In article one, the community of educators' conversations were critically analyzed to discern the challenges educators encountered when they attempted to connect school curriculum to energy exhibits at the Urban Science Center. The five challenges that characterize the emergence of a third space were as follows: (a) science terminology for lesson focus, (b) "dumb-down" of science exhibits, (c) exploration distracts

    The prevalence of HIV&AIDS is embedded in social and economic inequity and the relationship between social determinants and HIV incidence is well established. The aim of this study was to determine which socio-economic and demographic factors are related to HIV status in the age group 18 to 49 years in informal settlements in the Eastern Cape, South Africa. This cross-sectional study was conducted in 3 informal settlements (n = 752) during March 2013 within the Nelson Mandela Bay and Buffalo City districts. A proportional cluster sample was selected and stratified by area and formal plot/squatter households in open areas. Respondents who volunteered to participate had to provide informed written consent before trained, bilingual peer educators interviewed them and completed the structured questionnaire. HIV status was determined and information on demographic and socio-economic variables was included in the bivariate analysis. The prevalence of HIV was higher, at 17.3%, than the 2011 estimated national prevalence among the general population in South Africa. The level of education (χ(2) = 5.50, df = 1, p food insecurity (χ(2) = 4.77, df = 1, p < 0.05), cooking with cast iron pots (χ(2) = 15.0, df = 3, p < 0.05) and availability of perceived 'wealth' indicators like mobile telephones and refrigerators (χ(2) = 9.67, df = 2, p < 0.05) were significantly associated with HIV-status. No significant associations could be demonstrated between household income, the number of people living in the household and the availability of electricity/water and HIV status. As the observed levels of HIV prevalence underlined gender bias and failure to graduate from high school, future interventions should focus on HIV prevention in female schoolchildren. However, HIV infection is also prevalent among wealthier individuals in informal settlements, which indicates that renewed efforts should be made to improve sexual risk behaviour within this group.

  14. Determination of Informal Sector as Urban Pollution Source : Fume Characterization of Small-scale Manual Metal Arc Welding using Factor Analysis in Bandung City

    Full Text Available In developing countries, the informal sector, particularly small-scale welding activities, are considered to be an important contributor to urban air pollution although studies in this sector are limited. This study aims to identify the composition of small-scale welding fume in order to further investigate the effects and set control strategies and urban pollution abatement policies. Breathing zone air samples were collected from 30 mild steel manual metal arc welders and 17 non-welders in Bandung City, West Java, Indonesia. The respirable particulates in air samples were analyzed using gravimetric method, and Instrumental Neutron Activation Analysis (INAA was employed to identify characteristic of welding fume. It was found that respirable particulates concentration in welders (range : 315.6 and 3,735.93 µgm-3; average 1,545.436 µgm-3 were significantly higher than in non-welders (range : 41.84 and 1,688.03 µgm-3; average : 375.783 µgm-3. Welders’ breathing zones contain Fe>Na>K>Mn>Al >Cr>Ti>Cl>Br>I>Zn>Sb>V>Co>Sc; while non-welders’ breathing zones contain Cr>F>Al>Ti>Na>Br>I>Mn>Cl>Co>Zn>Sc. Inter-species correlation analysis conducted using Statgraphic Ver. 4.0 shows that Fe (range : n.d. – 775.19 µgm-3; average: 0.1674 µgm-3, Co (range : n.d. – 0.51 µgm-3; average: 0.000082 µgm-3, Mn (range : 0.39 – 148.37 µgm-3; average: 0.0374 µgm-3, Na (range: 0.17 and 623.85 µgm-3; average: 0.0973 µgm-3 and K (range : n.d. – 301.15 µgm-3; average: 0.0535 µgm-3 were emitted from welding activity, and thus are considered as components of welding fume which contribute to urban air pollution. Although welding fume and the identified species in welding fume were still below permissible limit, small-scale welding activities have great potential in emitting higher fume concentration due to due to high variability of welding activities, such as welding frequency, materials being welded, and varied environmental conditions

    Full Text Available Cities present significant opportunities for new landscape perspectives that can help inform conservation and development decisions. Early in the twenty-first century, the majority of the planet’s population became urban as more people lived in city-regions for the first time in our history. As the global population increases, so does this urbanization. The environmental challenges of population and urban growth are profound. Landscapes represent a synthesis of natural and cultural processes. Cities are certainly cultural phenomena. Historically, cities provided refuge from nature. The expanding field of urban ecology, coupled with landscape ecology, can enhance how the dual natural and cultural dimensions of landscapes in cities are understood. Furthermore, concepts such as ecosystem services and green infrastructure are proving useful for urban landscape planning and design. Examples from Dayton, Ohio; Brooklyn, New York; and Austin, Texas are presented.

    Full Text Available Introduction: Present study describes the antimicrobial activity and free radical scavenging capacity (RSC of essential oil from Mentha longifolia (L. Huds. Aim of this study to investigate the quality, antimicrobial andantioxidant activity of wild species Mentha longifolia essential oil from Bosnia and Herzegovina.Methods: The chemical profi le of essential oil was evaluated by the means of gas chromatography-mass spectrometry (GC-MS and thin-layer chromatography (TLC. Antimicrobial activity was tested against 6bacterial strains. RSC was assessed by measuring the scavenging activity of essential oils on 2,2- diphenyl-1-picrylhydrazil (DPPH.Results: The main constituents of the essential oil of M. longifoliae folium were oxygenated monoterpenes,piperitone oxide (63.58% and 1,8-cineole (12.03%. Essential oil exhibited very strong antibacterial activity.The most important antibacterial activity essential oil was expressed on Gram negative strains: Escherichia coli, Pseudomonas aerginosa and Salmonella enterica. subsp.enterica serotype ABONY. Antioxidant activity was evaluated as a RSC. Investigated essential oil was able to reduce DPPH radicals into the neutral DPPHH form (IC50=10.5 μg/ml and this activity was dose –dependent.Conclusion: The study revealed signifi cant antimicrobial activity of the investigated essential oil. The examined oil exhibited high RSC, which was found to be in correlation to the content of mainly monoterpeneketones and aldehydes. These results indicate that essential oils could serve as safe antioxidant and antiseptic supplements in pharmaceuticals.

    Full Text Available Using Satellite Remote Sensing and Geographic Information System, this paper analyzes the land use and land cover change dynamics in the Bosomtwe District of Ghana, for 1986, 2010 thematic mapper and enhanced thematic Mapper+ (TM/ETM+ images, and 2014 Landsat 8 Operational Land Imager and Thermal Infrared Sensor (OLI/TIS image. The three images were geo-referenced and processed for classification, using the maximum likelihood classifier algorithm. A Jeffries-Matusita’s separability check was used in confirming the degree of spectral separation acceptability of the bands used for each of the land use and land cover classes. The best Kappa hat statistic of classification accuracy was 83%. Land Use and Land Cover (LULC transition analysis in Environmental Systems Research Institute ESRI’s ArcMap was performed. The results of the classification over the three periods showed that built up, bare land and concrete surfaces increased from 1201 in 1986 to 5454 ha in 2010. Dense forest decreased by 2253 ha over the same period and increased by 873 ha by the 2014. Low forest also decreased by 1043 ha in 2010; however, it increased by 13% in 2014. Our findings showed some of the important changes in the land use and land cover patterns in the District. After the urbanization process, coupled with farmland abandonment, between 1986 and 2010, substantial increments in urban land and clear increments in farmland coverage between 1986 and 2014were found to be the reason for vegetation cover decreases. This suggests that major changes in the socio-ecological driving forces affecting landscape dynamics have occurred in the last few decades.

    HIV risk in vulnerable groups such as itinerant male street labourers is often examined via a focus on individual determinants. This study provides a test of a modified Information-Motivation-Behavioral Skills (IMB) model to predict condom use behaviour among male street workers in urban Vietnam. In a cross-sectional survey using a social mapping technique, 450 male street labourers from 13 districts of Hanoi, Vietnam were recruited and interviewed. Collected data were first examined for completeness; structural equation modelling was then employed to test the model fit. Condoms were used inconsistently by many of these men, and usage varied in relation to a number of factors. A modified IMB model had a better fit than the original IMB model in predicting condom use behaviour. This modified model accounted for 49% of the variance, versus 10% by the original version. In the modified model, the influence of psychosocial factors was moderately high, whilst the influence of HIV prevention information, motivation and perceived behavioural skills was moderately low, explaining in part the limited level of condom use behaviour. This study provides insights into social factors that should be taken into account in public health planning to promote safer sexual behaviour among Asian male street labourers.

Occupy Wall street and its action in the autumn 2001 is the ultimate example of how urban political performances intensifies and transform every day spaces. Through examples of how OWS tactically appropriates and transforms urban....... Whereas urban planners and architects worldwide call for user participation governed by the authorities, these urban performances act. On the backdrop of their acting of ideas in public, I propose a potential for urban transformation taking urban social diversity as its point of departure....
