    Full Text Available Background: Although the Indian girl child′s position is precarious throughout the country, she remains the most vulnerable in Punjab. Objectives: To assess the awareness and perceptions of school children regarding female feticide. Study Design: Cross- sectional study. Materials and Methods: The study involved collection of information regarding knowledge and perception of school students about female feticide using multiple choice questionnaire. A total of 527 students between the age group of 11-18 years of various schools of district Ludhiana, Punjab were the study subjects. They had come to participate in the poster competition on organ donation (SAARC Transplant games, organized by Department of Community Medicine, D.M.C and H, Ludhiana. Results: Out of total 527 students, 97.9% were aware of female feticide. Main source of information was TV (56%, followed by newspaper (33%. Majority of the students (65.2 % felt that discrimination between boys and girls is prevalent in the society. Regarding perception of school students for curbing this social evil, 37.8% school students were of the view that awareness among the masses is the solution to stop this practice, while 25% of the students responded that equal status to girls will stop this practice of female feticide. Conclusions: The school students had optimum level of awareness about female feticide and almost all of them strongly felt that this harmful practice should be stopped altogether.

    Energy gap is the main nutritional factor which affects work efficiency in all age groups. The low intake of food results in impaired working efficiency and a low level of vitality. Energy balance was evaluated among 30 healthy, nonpregnant, nonlactating housewives aged 29-40 years drawn from the campus of Punjab Agricultural University and its surrounding areas. The women's mean overall energy intake was 1777 +or- 31 kcal/day, 87% of the ICMR (1990) recommended allowances. Total energy expenditure was measured using a computer-based Nutriguide program of Song et al., Caltrac, FAO/WHO/UNU (1985) equations based upon body weight, and an ICMR (1990) prediction equation also based upon body weight. Statistical analysis identified a significant difference in the energy expenditure measured by all 4 methods except between the FAO/WHO/UNU and ICMR prediction equations. The overall energy balance was maximum and positive according to Caltrac at 4.5 kcal/day. The energy expenditure measured by the Nutriguide, FAO/WHO/UNU, and ICMR methods was significantly correlated to weight. Energy intake was significantly and highly correlated to energy balance in all of the 4 methods. While the subjects were overweight when compared with Life Insurance Corporation of India (1965) Standards, the women's body mass index of 23.11 kg/sq.m was within the normal range.

    The microbiological quality of bottled mineral water marketed in Ludhiana was examined, Twenty three brands were analyzed for presumptive coliform count by multiple tube tests, and E. coli count was confirmed by Eijkman test. Bacterial and fungal loads were tested by membrane filtration test. Out of 23 only one sample (4.4%) showed the presumptive coliform count to be 460 most probable number (MPN)l 1 00ml,and 1 was found to be positive when tested by Eijkman test for Ecoli. In the membrane filtration test three samples (13%) showed more than two types of bacteria. Different types of bacteria isolated included Bacillus sp (19/23). Pseudomonas spp (13123), Ecoli, Klebsiella sp and S.albus one each Fungi was isolated from five of twenty three. (22%) samples. Only one brand of mineral water was unfit for human consumption. The rest of the samples were contaminated with non pathogenic flora.

    Soil and plant samples were collected from sewage and tubewell irrigated sites from three industrially different cities of Punjab (India) viz. Ludhiana, Jalandhar and Malerkotla. The extent of lead (Pb) pollution was assessed with respect to background concentration of tubewell irrigation. In sewage irrigated surface soil layer (0-15 cm), the extent of Pb accumulation was 4.61, 4.20 and 2.26 times higher than those receiving tubewell irrigation sites in Ludhiana, Jalandhar and Malerkotla, respectively. Multiple regression analysis showed that soil pH, organic carbon, calcium carbonate and clay were significant soil parameters explaining the variation in available soil Pb. The mean Pb content in plants receiving sewage irrigation was 4.56, 5.48 and 2.72 times higher than tubewell irrigation in Ludhiana, Jalandhar and Malerkotla, respectively. The content of Pb in plants receiving sewage irrigation revealed that, assuming a weekly consumption of 500-1000 g of vegetables grown on sewage irrigated soils by an adult of 70 kg body weight, the Pb intake may far exceed the World Health Organization proposed tolerable weekly intake of Pb.

    Full Text Available 3D city model is a digital representation of the Earth’s surface and it’s related objects such as building, tree, vegetation, and some manmade feature belonging to urban area. The demand of 3D city modeling is increasing rapidly for various engineering and non-engineering applications. Generally four main image based approaches were used for virtual 3D city models generation. In first approach, researchers were used Sketch based modeling, second method is Procedural grammar based modeling, third approach is Close range photogrammetry based modeling and fourth approach is mainly based on Computer Vision techniques. SketchUp, CityEngine, Photomodeler and Agisoft Photoscan are the main softwares to represent these approaches respectively. These softwares have different approaches & methods suitable for image based 3D city modeling. Literature study shows that till date, there is no complete such type of comparative study available to create complete 3D city model by using images. This paper gives a comparative assessment of these four image based 3D modeling approaches. This comparative study is mainly based on data acquisition methods, data processing techniques and output 3D model products. For this research work, study area is the campus of civil engineering department, Indian Institute of Technology, Roorkee (India. This 3D campus acts as a prototype for city. This study also explains various governing parameters, factors and work experiences. This research work also gives a brief introduction, strengths and weakness of these four image based techniques. Some personal comment is also given as what can do or what can’t do from these softwares. At the last, this study shows; it concluded that, each and every software has some advantages and limitations. Choice of software depends on user requirements of 3D project. For normal visualization project, SketchUp software is a good option. For 3D documentation record, Photomodeler gives good

    Objective To evaluate clinical and hematological aspects of dogs naturally infected with Hepatozoon canis (H. canis) presented at the Small Animal Clinics of Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana. Methods Blood films of 34 naturally infected dogs were examined for haematological alterations and parasitaemia. Signalment and clinical signs were recorded from the animals. Clinical histories were filled out during the consultation. Results Of the 34 positive dogs by Giemsa stained peripheral blood films, 88.23% presented parasitaemia by H. canis only, while 11.77% had the combination of H. canis, Babesia sp. and Ehrlichia sp. Young male dogs less than one-year-old, of non-descript breed, were the most commonly affected. And 26.47% were presented with anorexia/inappetence as the only clinical symptom. Other clinical symptoms were mild to moderate fever, pale mucosae and lethargy; a few were also showing the signs of vomiting and diarrhoea. Haematological alterations showed mainly normochromic-normocytic anaemia, leukocytosis and neutrophilia. Conclusions The findings of this study substantiate that H. canis caused clinical and haematological alterations of the varied intensity in dogs, even with low parasitaemia, should be taken into consideration.

    2017-01-01

    The recent International Panel on Climate Change report predicts the highly urbanized Northeastern U.S. to be at high risk to heat waves. Since urban residents and infrastructure are known to be highly vulnerable to extreme heat, the goal of this paper is to understand the interaction between the synoptic-scale heat wave and the city-scale urban heat island (UHI) effects. The study also qualitatively analyzes the primary factors that contribute to UHIs by comparing their intensities in different cities with distinct geo-physical characteristics. Our results, generated by using the Weather Research and Forecasting model augmented with advanced urban surface parameterizations, confirm that the amplitude of UHI is related to the physical size of the city. However, the results suggest that cities of comparabale sizes might interact differently with heat waves: in New York City; Washington, DC; and Baltimore (but not in Philadelphia) the regular UHI was amplified more strongly during heat waves compared to smaller cities. The results also establish that the pattern of UHI in different cities, its variability, and its interaction with heat waves are inherently linked to dynamic factors.

    Full Text Available Context: As psychiatric illness requires long-term treatment, some patients are lost to follow-up. Aims: The present study aimed to find the follow-up pattern of psychiatric patients attending psychiatry outpatient department (OPD and to determine the correlation of follow-up with socio-demographic profile and diagnosis, if any. Settings and Design: This study was a retrospective data analysis study carried out at the OPD of Psychiatry, Christian Medical College and Hospital, Ludhiana. Subjects and Methods: New cases attending the OPD from April 2010 to March 2011 were included in this study. The data were scrutinized 1 year after the initial assessment. Socio-demographic data, diagnosis and follow-up information were obtained from the files. The collected data were statistically analyzed. Statistical Analysis Used: Chi-square and P value. Results: 53.1% of the patients dropped out after first visit, 29.4% patients had 1-3 follow-up, 14.9% had 4-10 follow-ups and only 2.6% had more than 10 follow-ups. Correlation between follow-up and various socio-demographic variables such as age, gender, place of living or distance from hospital, occupation, religion and marital status was not statistically significant. It was, however, seen that cognitive disorders, conversion disorder, mental retardation, and patients in which diagnosis was deferred, had more dropout rate after first visit. Conclusions: In our study 53.1% of the patients did not attend follow-up at all and only 2.6% had more than 10 follow ups. Correlation between follow-up and various socio-demographic variables was not statistically significant. Patients in which diagnosis was deferred had more drop out rate than patients who had a diagnosis and the difference was statistically significant.

    The international literature has paid significant attention to presenting China as the largest emitter of greenhouse gases (GHGs) in the world, despite having much lower per-capita emissions than the global average. In fact, the imbalance of economic development leads to diversity in GHG emissions profiles in different areas of China. This paper employs a common methodology, consistent with the Sustainable Energy Action Plan (SEAP) approved by the Covenant of Mayors (CoM), to estimate CO 2 emissions of four Chinese cities in highly urbanized areas from 2004 to 2010. The results show that the CO 2 emissions of all four cities are still rising and that secondary industries emit the most CO 2 in these cities. By comparing these data with the inventory results of two European cities, this paper further reveals that Chinese cities in highly urbanized areas contribute much higher per-capita emissions than their European competitors. Furthermore, the per-capita CO 2 emissions of the residential sector and private transport in these Chinese cities are growing rapidly, some of them approaching the levels of European cities. According to these findings, several policy suggestions considering regional disparities are provided that aim to reduce the CO 2 emissions of highly urbanized areas in China. - Highlights: ► An exemplary study of GHG emission inventory for Chinese cities. ► Estimate CO 2 emissions of Chinese city in highly urbanized areas from 2004 to 2010. ► The studied Chinese cities contribute higher per-capita emissions than European’s. ► Emissions of residential sector and private transport in China are growing rapidly. ► Several policy suggestions considering regional disparities are provided.

    Sustainability must be an urban issue. Cities should be managed so as to minimize their impacts on environment, but providing an appropriate framework for economic and social development. However, European cities are facing some trends that threaten sustainable development. The aim of the EC research project INSIGHT-7FP (2013/16) is to develop appropriate management tools that can help to achieve sustainability in the context of European cities. In the project, a set of policy objectives have been designed for the management of urban areas, in order to face the main threats existing over cities. The paper presents a methodology based on indicators for analysing the progress towards these ten policy objectives in the four EU cities participating in the project: London (12.3 mill. inhab.), Madrid (6.4 mill. inhab.), Barcelona (5.4 mill. inhab.) and Rotterdam (1.4 mill. inhab.). All the indicators used in the analysis have been validated by ten policy makers of European cities. These policy makers participated on the stakeholders consultation carried out in the project, where the importance of the policy objectives proposed was also assessed. The paper concludes determining the policy priority objectives in each city, in order to contain the main threats existing over them: London should especially address the threats of social exclusion and transport inefficiency; Madrid the threats of economic decline and urban sprawl; Barcelona the economic decline and Rotterdam the contribution to climate change and the urban sprawl. Finally, the role played by the land use and transport system in these policy objectives is analysed. To this end, the assessment allows for the comparability of the results in a horizontal manner, in the basis of common indicators. Nearly half of these indicators are related to the land use and transport system of the cities. (Author)

    High levels of 'excess' mortality (ie, that seemingly not explained by deprivation) have been shown for Scotland compared to England and Wales and, especially, for its largest city, Glasgow, compared to the similarly deprived English cities of Liverpool and Manchester. It has been suggested that this excess may be related to differences in 'Sense of Coherence' (SoC) between the populations. The aim of this study was to ascertain whether levels of SoC differed between these cities and whether, therefore, this could be a plausible explanation for the 'excess'. Three post-industrial UK cities: Glasgow, Liverpool and Manchester. A representative sample of more than 3700 adults (over 1200 in each city). SoC was measured using Antonovsky's 13-item scale (SOC-13). Multivariate linear regression was used to compare SoC between the cities while controlling for characteristics (age, gender, SES etc) of the samples. Additional modelling explored whether differences in SoC moderated city differences in levels of self-assessed health (SAH). SoC was higher, not lower, among the Glasgow sample. Fully adjusted mean SoC scores for residents of Liverpool and Manchester were, respectively, 5.1 (-5.1 (95% CI -6.0 to -4.1)) and 8.1 (-8.1 (-9.1 to -7.2)) lower than those in Glasgow. The additional modelling confirmed the relationship between SoC and SAH: a 1 unit increase in SoC predicted approximately 3% lower likelihood of reporting bad/very bad health (OR=0.97 (95% CI 0.96 to 0.98)): given the slightly worse SAH in Glasgow, this resulted in slightly lower odds of reporting bad/very bad health for the Liverpool and Manchester samples compared to Glasgow. The reasons for the high levels of 'excess' mortality seen in Scotland and particularly Glasgow remain unclear. However, on the basis of these analyses, it appears unlikely that a low SoC provides any explanation. Published by the BMJ Publishing Group Limited.

    Anthelmintic resistance against commonly used anthelmintic fenbendazole was evaluated by employing faecal egg count reduction test (FECRT) in naturally occurring gastrointestinal (GI) nematodes in the semi organized sheep and goat farms of Ludhiana and Amritsar districts. A total of 80 animals (20 each for sheep and goat in both districts) were randomly selected and their faecal samples were examined by qualitative and quantitative parasitological techniques. Results indicate presence of high level of resistance against fenbendazole in both sheep and goat population of Ludhiana and Amritsar districts. More resistance was observed in the GI nematodes from animals reared in Amritsar district as compared to Ludhiana district. The level of anthelmintic resistance observed was apparently more in sheep than goats.

    Cities are at the forefront of efforts to combat climate change and in this paper, we examine the influence of urban energy governance on these policy goals. An innovative framework for quantifying the combined governance of cities and energy systems is presented before focusing on a detailed study of London, Paris, Berlin and Copenhagen. By applying an optimization model to assess the lowest cost technology pathways to achieve emission reduction targets, the links between the governance of urban energy systems and the cost of achieving carbon targets are shown. Additionally a novel metric of scenario similarity is introduced in order to evaluate the difficulty of hypothesized energy system transitions. The results indicate that these tools can be valuable in identifying similar cities for the sharing of best practice, for performing comparative evaluations of energy transitions, and for reinforcing the need to complement quantitative assessments with a more holistic appreciation of local context. - Highlights: • Novel framework for comparing urban energy systems and their governance is presented. • Applied to four European cities with focus on climate change issues. • Bhattacharyya's distance introduced as measure of energy system scenario similarity. • Results suggest Paris is closest to its 2020 climate goals, London furthest

  17. Towards resilient cities. Comparing approaches/strategies

    Full Text Available The term “resilience” is used in many disciplines with different meanings. We will adopt the ecological concept of resilience, which epitomises the capacity of a system to adapt itself in response to the action of a force, achieving a state of equilibrium different from the original (White, 2011. Since the end of the last century, with a significant increase over the last few years, resilience has featured as key concept in many technical, political papers and documents, and appears in many researches. Of all this recent and varied range of literature, our focus is on those texts that combine resilience with strategies, processes and models for resilient cities, communities and regions. Starting from the resilience strategies developed as response for risks mitigation, the paper thus explores other approaches and experiences on cities resilience that have been conducted: the aim is to compare and identify innovation in the planning process towards risks mitigation. In this paper we present a summary of the initial survey stage of our research, with three main aims: understanding the approaches to resilience developed so far and identifying which aspects these approaches share (or not;understanding which strategies are being proposed for resilient regions, cities or social-ecological systems;understanding whether proposed resilience strategies involve innovations in urban and regional development disciplines. The aim is to understand whether the proposed concept of resilience, or rather strategies, constitute progress and contribute to innovation in the areas of urban planning and design in relation to risk mitigation. Three main families of literature have been identified from the recent literature promoting resilience as a key strategy. The first aim of the research is to understand which particular concept and which aspects of resilience are used, which resilience strategies are proposed, how the term ‘city’ is defined and interpreted

    In many countries around the world, smart cities are becoming a reality. These cities contribute to improving citizens' quality of life by providing services that are normally based on data extracted from wireless sensor networks (WSN) and other elements of the Internet of Things. Additionally, public administration uses these smart city data to increase its efficiency, to reduce costs and to provide additional services. However, the information received at smart city data centers is not always accurate, because WSNs are sometimes prone to error and are exposed to physical and computer attacks. In this article, we use real data from the smart city of Barcelona to simulate WSNs and implement typical attacks. Then, we compare frequently used anomaly detection techniques to disclose these attacks. We evaluate the algorithms under different requirements on the available network status information. As a result of this study, we conclude that one-class Support Vector Machines is the most appropriate technique. We achieve a true positive rate at least 56% higher than the rates achieved with the other compared techniques in a scenario with a maximum false positive rate of 5% and a 26% higher in a scenario with a false positive rate of 15%.

    We compared characteristics of homicides among New York City residents aged 18 years and older from 1990 to 1998 to determine differences in demographics, cause and place of death, and presence of illicit drugs and alcohol in the deceased's system. All medical examiner-certified homicides among New York City residents aged 18 years and older from 1990 to 1998 were studied (n = 11,850). Nonelderly (aged 18 to 64 years) and elderly (aged 65 years and older) victims were compared by gender, race/ethnicity, cause of death, place of death, and presence of illicit drugs or alcohol. Population-based homicide rates stratified by age, gender, and race were also calculated. Nonelderly homicide victims were significantly more likely to be male, non-White, to have been shot in the city streets, and to have evidence of illicit drug or alcohol use. Elderly victims were more likely to be female, White, to have been killed by nonfirearm injuries, and to have been killed in their own homes. The gender and race differences between age groups remained but were attenuated when population-based rates were compared. The characteristics of homicide in nonelderly adults do not apply to elderly adults in New York City. Demographic factors and vulnerabilities of the elderly may underlie these differences, pointing to the need for oversight of isolated or homebound elderly persons and for protective interventions.

Yet there is too little systematic comparative research on the practice of urban health policy and management (HPAM, particularly in the megacities of middle-income and developing nations. We make a case for creating a global database on cities, population health and healthcare systems. The expenses involved in data collection would be difficult to justify without some review of previous work, some agreement on indicators worth measuring, conceptual and methodological considerations to guide the construction of the global database, and a set of research questions and hypotheses to test. We, therefore, address these issues in a manner that we hope will stimulate further discussion and collaboration.

We, therefore, address these issues in a manner that we hope will stimulate further discussion and collaboration. © 2016 by Kerman University of Medical Sciences.

    Full Text Available China’s resource-based cities have currently entered a period of comprehensive transformation. The differences in the economic and technical environment and significant policy orientation make it unique to some extent. This study applied value chain theory to analyze the industrial value chain of China’s resource-based cities, and three important types of optimization paths that have been applied differently by different cities were proposed. Grey relational analysis was used to compare the comprehensive value creation capacity of the three paths and its relationship with the comparative advantage of local industry. We found that a circular economy system has significant capacity to optimize economic and social value and favorable prospects for environmental value. However, this may have obvious instability in early periods of transition. This disadvantage can be remedied by cultivating related industries that have significantly comprehensive advantages in the early period. In the long term, the other two paths need to be combined with cultivating emerging industries. Finally, we found that the value creation capacity of China’s resource-based cities has roots in optimization of the industrial value chain rather than enhancement of the industrial comparative advantage. The reason for this is that value creation capacity has not yet been transformed into a source of industrial comparative advantage.

    Full Text Available Smart cities link the city services, citizens, resource and infrastructures together and form the heart of the modern society. As a “smart” ecosystem, smart cities focus on sustainable growth, efficiency, productivity and environmentally friendly development. By comparing with the European Union, North America and other countries, smart cities in China are still in the preliminary stage. This study offers a comparative analysis of ten smart cities in China on the basis of an extensive database covering two time periods: 2005–2007 and 2008–2010. The unsupervised computational neural network self-organizing map (SOM analysis is adopted to map out the various cities based on their performance. The demonstration effect and mutual influences between these ten smart cities are also discussed by using social network analysis. Based on the smart city performance and cluster network, current problems for smart city development in China were pointed out. Future research directions for smart city research are discussed at the end this paper.

  8. Integration Policies of European Cities in Comparative Perspective: Structural Convergence and Substantial Differentiation

    Directory of Open Access Journals (Sweden)

    Full Text Available This article aims to review the comparative study of integration policies of European cities. The first two sections present an analytical framework for the study of immigrants’ integration processes and the policies that intend to steer such processes. The third section outlines how local integration policies have developed in relation to national policies and EU integration policies, particularly after 2003. The fourth and main section analyses the framing and content of integration policies of European cities, looking at their diversity in the legal/political dimension, the socio-economic dimension – including the domains of work, housing, education and health – and the cultural, religious and ethnic dimension. It is concluded that there is a structural convergence, in the sense that in the complex structure of multilevel governance of migration and integration, cities do take a similar position, developing horizontal relations of cooperation and exchange. Cities that develop explicit integration policies tend to do this from a more inclusive and pragmatic framing than national and EU-policies. At the same time, there is great variation in what cities actually do: in the legal/political and in the cultural/religious dimensions, framing, intentions and measures do vary greatly; in the socio-economic dimension this variation is less when it comes to the domains of activity, but more in the intensity of policy intervention.

    2007-01-01

    Objectives. We compared characteristics of homicides among New York City residents aged 18 years and older from 1990 to 1998 to determine differences in demographics, cause and place of death, and presence of illicit drugs and alcohol in the deceased’s system. Methods. All medical examiner–certified homicides among New York City residents aged 18 years and older from 1990 to 1998 were studied (n = 11 850). Nonelderly (aged 18 to 64 years) and elderly (aged 65 years and older) victims were compared by gender, race/ethnicity, cause of death, place of death, and presence of illicit drugs or alcohol. Population-based homicide rates stratified by age, gender, and race were also calculated. Results. Nonelderly homicide victims were significantly more likely to be male, non-White, to have been shot in the city streets, and to have evidence of illicit drug or alcohol use. Elderly victims were more likely to be female, White, to have been killed by nonfirearm injuries, and to have been killed in their own homes. The gender and race differences between age groups remained but were attenuated when population-based rates were compared. Conclusions. The characteristics of homicide in nonelderly adults do not apply to elderly adults in New York City. Demographic factors and vulnerabilities of the elderly may underlie these differences, pointing to the need for oversight of isolated or homebound elderly persons and for protective interventions.

    2016-01-01

    The energy efficiency of existing commercial buildings is more challenging to regulate and improve than the energy efficiency of new constructions. In 2011 and 2012, the Chinese Government selected four cities- Shanghai, Tianjin, Shenzhen, and Chongqing- to implement pilot commercial building energy efficiency retrofit program. Based on site surveys and expert interviews in these pilot cities, this research conducted a comparative analysis on incentive policies of local city level. The analysis results show that policy designs of existing commercial buildings should be further improved. The aspects that influence the implementation effect in the future, such as subsidy level, installments, and business model promotion, should be specified in the policy clauses. Referring to the technical solution and cost-benefit in Chongqing, we found that lighting system is the most common retrofit objects while envelope system is the least common one. And the subsidy incentive is greatest for educational buildings, followed by office buildings. In the end, we further discussed the problems and obstacles in commercial building retrofit market, and provided a series of recommendations. - Highlights: • Data and information were collected through site surveys to the four pilot cities. • Policy design and effectiveness in four cities were comparatively analyzed. • Well-designed policy increases market response, energy savings and EMC adoption. • Lighting is the most common retrofit while envelope is the least common one. • Subsidy incentive is greatest for educational buildings due to the utility tariff.

    The road transport sector is the major emission source of toxic air pollutants and greenhouse gases (GHGs) in large Asian cities. This paper comparatively analyzed on-road passenger traffic fleets (cars, buses, taxis, motorcycles), using local data collected in cities of Bangkok (BKK), Kathmandu, Hanoi, Ho Chi Minh City (HCMC), and Yangon. Surveys were done in 2010-2014 to obtain information on vehicle technology, driving activities (speed, distance, number, and types of starts), traffic density, and fuel characteristics. Large shares of pre-Euro vehicles were still observed, especially for public buses. The most advanced technology was Euro4, which was observed in small shares (<5%) of the personal car fleets in BKK, HCMC, and Yangon. Euro3 was generally the most advanced technology found in other fleets in these cities. Motorcycles (MC) was the most dominant fleet in all cities, except in Yangon, where they were not allowed. Low vehicle speeds, mainly below 25 km/h, were observed for all vehicle types, indicating traffic jams. Natural gas and LPG had considerable shares in BKK and Yangon while for other cities diesel and gasoline were still the two major fuels used in transportation. Running emission factors (EF) of buses and taxis in Kathmandu were considerably higher than other cities due to its hilly topography, low speeds, high mileage, and less advanced vehicle technologies. The number of passenger vehicles per 1000 people were 400-500 in HCMC and Hanoi (mainly by MC) and in BKK (also by cars), moderate in Kathmandu (200) and the lowest in Yangon (40) because of the MC ban. Annual emissions of the passenger fleets were calculated for each city using the International Vehicle Emission (IVE) for 14 species. BC and OC emissions were estimated using their fractions of PM10 emission. Annual emission per capita of toxic air pollutants and GHGs was analyzed. For example, the emission in kg/year/person for CO, VOC, NOx and PM10 in these cities was 24-150 for CO, 0

    Full Text Available Objective: To compare the growth curves from a population from a large city suburban hospital with those of the city of São Paulo, São Paulo State, Brazil. Methods: At Hospital Geral do Grajaú, that serves the high pregnancy risk population lacking health facilities, of low education level and smaller number of prenatal visits and great morbidity, a growth curve was built for the newborns, as the Hospital is provided with updated equipment and personnel. The curve was built from the database available containing information on live births during the 2003 to 2007 period and totaling 9,952 newborns, as their weight at birth and gestational age were taken as parameters. The distribution curves of 3%, 10%, 50% and 90% of the Grajaú were compared to those of the city of São Paulo curve. Results: The curves did not significantly differ from those of the São Paulo curve percentiles, as shown by the mean deviation (Z score calculation, notwithstanding the higher rates for prematurity, low weight, teenager mothers and lack of prenatal visits among the Grajaú population as compared to those of São Paulo. Conclusions: The São Paulo city curve showed to be appropriate for the suburban population despite the existing differences.

    Self-medication with antibiotics may result in antimicrobial resistance and its high prevalence is of particular concern in Low to Middle Income Countries (LMIC) like Guatemala. A better understanding of self-medication with antibiotics may represent an opportunity to develop interventions guiding the rational use of antibiotics. We aimed to compare the magnitude of antibiotic self-medication and the characteristics of those who self-medicate in two pharmacies serving disparate socio-economic communities in Guatemala City. We conducted a descriptive, cross-sectional study in one Suburban pharmacy and one City Center pharmacy in Guatemala City. We used a questionnaire to gather information about frequency of self-medication, income and education of those who self-medicate. We compared proportions between the two pharmacies, using two-sample z-test as appropriate. Four hundred and eighteen respondents completed the survey (221 in the Suburban pharmacy and 197 in the City Center pharmacy). Most respondents in both pharmacies were female (70%). The reported monthly income in the suburban pharmacy was between $1,250.00-$2,500.00, the city-center pharmacy reported a monthly income between $125.00- $625.00 (p Guatemala City. Additionally, self-medicating respondents were most often women and most commonly self-medicated with amoxicillin. Our findings support future public health interventions centered on the regulation of antibiotic sales and on the potential role of the pharmacist in guiding prescription with antibiotics in Guatemala.

    Full Text Available Background: Exponential growths of population and urbanization, and the development of social economy have resulted in an increase in the amount of MSW generation throughout the world. Objective: The present study aimed to survey qualitative and quantitative analysis of solid waste in Shiraz city and comparative these results with the world scenario of solid wastes generation for improving the sustainable management of solid waste. Methods: This cross-sectional study was conducted in 2014 in nine municipality regions Shiraz with a total population of approximately 1,549,354 people. Basic data was gathered through Shiraz waste management organization. Then generation (per capita and constituent percent of the solid waste were evaluated based on the sampling and field analyzing from reliable guidelines. Data were analyzed with Stata-13 and Excel statistical software. Kolmogorov-Smirnov test used for the normality of variables. Means were compared by Student T test and Mann-Whitney test. Findings: The rate of solid waste generated in the Shiraz city was 222.65 kg per person per year in 2014. Statistical analysis showed that the variables of organic materials, paper and cardboard, glass and metal between developed and developing countries were a significant difference (P0.05. Conclusion: Solid waste per capita in Shiraz city (about 600 g/day was near to the average amount of solid waste generation in Iran and other developing countries. Due to the high content of organic material in municipal solid waste of Shiraz, minimization of these material and separation of dry and wet solid wastes must be noted from the people and municipalities.

    2006-04-01

    Apheresis has now become an internationally popular mode of treatment for multiple immune complex disorders. However, the treatment remains quite expensive in Western Europe and the US. Apheresis tourism is a part of medical tourism or medical tourism specially related to therapeutic apheresis (TA) treatment in a foreign country on a cost effective basis. In the last couple of years, 'Medical Tourism' has become an upcoming and growing enterprise in India. The Indian Society for Apheresis (ISA) has taken a plunge at the opportune time and is trying to promote apheresis tourism in India. ISA is a member of various international apheresis organizations globally including the World Apheresis Association (WAA), the International Society for Apheresis (ISFA), the International Society for Artificial Organs (ISAO) and an associate of other national apheresis societies. The Indian Society for Apheresis (ISA) and the Ludhiana MediCiti (LMC) at Ludhiana Punjab are taking a big step in this direction. The therapeutic apheresis (TA) center at LMC is being set up as a Therapeutic Apheresis Institute and Research Center of excellence. The potential future impacts on the apheresis scenario are summarized.

    This paper presents results from the international AcceptH2 study (http://www.accepth2.com) of acceptability and preferences for hydrogen fuel cell (FC) buses. Using the contingent valuation method, this paper compares public willingness to pay (WTP) for the air pollution reductions associated with a scenario of large-scale introduction of hydrogen (H 2 ) FC buses in four cities: Berlin, London, Luxembourg and Perth. Results indicate that bus users in all cities have a positive WTP for H 2 buses, and that values (adjusted to the cost of living in each city) are very similar across geographical locations (ranging from WTP an extra Euro 0.29 to Euro 0.35 per single bus fare). Non-bus users were also interviewed in London and Perth, in order to capture values for the whole populations in these cities. Combined results for bus users and non-bus users confirm that overall residents in these cities are willing to pay extra (in taxes) to support the large-scale introduction of H 2 -buses

  19. A Framework for city leadership in multilevel governance settings: the comparative contexts of Italy and the UK

    Directory of Open Access Journals (Sweden)

    Leslie Budd

    2016-01-01

    Full Text Available This paper discusses the role of city leadership in the current multilevel governance settings and provides a conceptual framework for understanding the main elements of city leadership. Forms of political, managerial and civic leadership have been distinguished within city leadership and the main actors, structures, processes and followership patterns are examined using Italy and the UK as starting points of comparison. This comparative framework sheds a light on some common and different features in the city leadership patterns in Italy and the UK, such as the cross-cutting and multilayered administrative context for public service delivery; the common trend towards strengthening the executive side of political leadership rather than the representative one; the growing relevance of forms of civic leadership as a trigger for creating public and social value and for enhancing the resilience of the territories. Main differences deal instead with the role of central government in defining the role of city leaders, where Italy seems to experience a return towards greater centralization and controls, and the UK is experiencing an opposite trend towards the empowerment of local communities. Finally, the paper sets out some future directions for the research agenda on city leadership we are seeking to pursue.

    Sexual behaviors in China are rapidly changing; simultaneously, sexually transmitted infections (STI)/HIV prevalence is increasing in the general population. To investigate these major shifts, we examined sexual behaviors and self-reported STI in one prefectural city in southern China, Liuzhou, and compared it to other prefectural cities throughout China. We used adults age 18-39 from two sets of population-based surveys that paralleled each other in both content and method. The first set was the Liuzhou survey conducted in 2008 (n = 398). The second set consisted of two national surveys collected in 2006 and 2010 (n = 2,186). Liuzhou respondents reported more active social and sexual behaviors than their national counterparts, including more socializing, dancing, drinking excessively, sexual activity among never married men and women, purchasing commercial sex among men, one-night stands among men, multiple sexual partnerships and self-reported STI among both men and women. Women in Liuzhou reported greater sexual risk behavior than their national counterparts, although overall they reported less than their male counterparts; they were also more likely to have had an abortion than women in other prefectural cities. Our findings provide a comprehensive overview of the sexual context of Liuzhou among the general population, which may help explain the greater STI/HIV prevalence in Liuzhou.

    Wei-Ju Huang

    2013-08-01

    Full Text Available High-tech development—which lies at the very heart of the processes of economic growth—has been recognised by many developed and developing countries as a strategic instrument to enhance and sustain their competitiveness in the global economic network. Although the concept of high-tech development differs between countries, many share the underlying assumption that the core of high-tech development is to create a sound environment where innovation thrives. This ideology implies a definite spatial dimension. As a result, various spatial strategies have been formulated and implemented to support high-tech development. This has had intentional and unintentional effects on the economy, society and space. Numerous studies have been devoted to exploring, analysing and theorising this global phenomenon. However, there has been less attention given to the role spatial planning may play in the process of high-tech development and to the factors that shape the spatial planning approaches to high-tech development in a particular place. The major objectives of this research are to advance the knowledge of the role of spatial planning in the process of high-tech development, and to establish an analytical framework that helps reveal the major institutional factors that shape spatial planning mechanisms for dealing with the spatial issues of high-tech development in different places. This contributes to the field of high-tech spatial policies transfer and lesson-drawing. In order to explore the major factors that shape the practices of spatial planning in hightech development, a comparative approach is applied in this research. The Eindhoven city-region in the Netherlands and the Hsinchu city-region in Taiwan are selected as case study areas. Both city-regions can be recognised as success stories of high-tech development not only on a national scale but also on a global scale, despite the fact that they apply different approaches.

    Though there have been several indicator systems to monitor the status quo of science and technology and of scientific literacy, few are especially designed for science culture, especially for its social dimension. Furthermore there is little agreement on how to measure it. In a previous study, an indicator system, SCI (Science Culture Indicators), had been developed to monitor the status quo of the science culture of a nation at both individual and social dimensions. The purpose of this study was to explore a practical way to measure and compare local cities' social foundation of science culture by revising and standardizing the social dimension of SCI and by applying it to five metropolitan cities in Korea. Despite some limits, the results of this study appear not only to reflect the cities' current situations but also to show the strength and weakness of their social foundation of science culture.

  6. Cities in Sustainability Transitions: Comparing Helsinki and Istanbul

    Directory of Open Access Journals (Sweden)

    Anna Kuokkanen

    2018-05-01

    Full Text Available Systemic sustainability transitions are manifested as the needed scope to meet sustainability challenges at the local and global scales. While sustainability transitions are ubiquitous, each transition is nested in a specific spatial context. Especially, due to accelerating urbanization, cities are increasingly important agents, but they are also understudied geographical loci of change. Urban transitions are interesting because they operate at both the national and global scales, concentrating people, wealth, and resources. They have both regime and niche elements, as they act as an incubation space for novel experiments, ideas, and alternative social movements. Thus, this paper aims to improve understanding of the geographical context and spatial scales from a multilevel perspective and develop a framework for analytic comparison. Furthermore, the paper draws insights from two empirical cases, namely the cities of Helsinki and Istanbul. Consequently, opportunities and challenges for instigating context-specific sustainability transitions can be identified.

    Caring for parents whose infant has died is extremely demanding, difficult, and stressful. In some situations, nurses may experience personal failure, feel helpless, and need to distance themselves from bereaved parents because they are unable to deal with the enormity of the parental feelings of loss. The aim of the study was to describe and compare attitudes toward perinatal bereavement care across a sample of nurses working in five obstetrics and gynecology settings from three Asian cities, as well as the factors associated with these attitudes. A survey was conducted, and 573 nurses were recruited from 2006 to 2007. The data were collected using the perinatal bereavement attitudes scale, which involves an 11-item self-report questionnaire. Nurses' attitudes were mainly positive, but differed across cities, with the attitude of Jinan nurses being significantly more positive than nurses from the other two cities, and the attitude of Hong Kong nurses being significantly the lowest. Positive attitudes were associated with position, and nurses who were well informed of hospital policy and received training for bereavement care were statistically significantly more likely to have a positive attitude toward perinatal bereavement care. Although nurses' attitudes to prenatal bereavement care differ significantly across the three Asian cities, they are generally similar. The differences observed could be related to the wider social, cultural, and organizational circumstances of nursing practice.

  8. How collaborative governance can facilitate quality learning for sustainability in cities: A comparative case study of Bristol, Kitakyushu and Tongyeong

    Quality learning for sustainability can have a transformative effect in terms of promoting empowerment, leadership and wise investments in individual and collective lives and regenerating the local economies of cities, making them more inclusive, safe, resilient and sustainable. It can also help cities move towards achieving the United Nations Sustainable Development Goals (SDGs). Effecting the transformation of cities into Learning Cities, however, requires changes in the structure of governance. Drawing on interviews with key informants as well as secondary data, this article examines how collaborative governance has facilitated quality learning for sustainability in Bristol (United Kingdom), Kitakyushu (Japan) and Tongyeong (Republic of Korea). Focusing on a conceptual framework and practical application of learning initiatives, this comparative study reveals how these cities' governance mechanisms and institutional structures supported initiatives premised on cooperative learning relationships. While recognising differences in the scope and depth of the learning initiatives and the need for further improvements, the authors found evidence of general support for the governance structures and mechanisms for learning in these cities. The authors conclude by recommending that (1) to implement the Learning Cities concept based on UNESCO's Key Features of Learning Cities, recognition should be given to existing sustainability-related learning initiatives in cities; (2) collaborative governance of the Learning Cities concept at both local and international levels should be streamlined; and (3) UNESCO's Global Network of Learning Cities could serve as a hub for sharing education/learning resources and experiences for other international city-related programmes as an important contribution to the implementation of the SDGs.

    Full Text Available The aim of this research paper is to compare the quality of education delivered at the undergraduate level in the public and private institutions of the Twin Cities (Islamabad and Rawalpindi in Pakistan. Data is collected with the help of questionnaires from 246 students. The data was collected from three public and three private educational institutions of the Twin Cities, and the age of students ranged from 18 to 27 years. The research instrument used in this paper is the independent sample t-test to find the difference between the three private and three public educational institutions selected in Rawalpindi and Islamabad in terms of different variables that are very important in measuring the quality of education. For analysis, Levene’s test was adopted, which reflects the variations in educational quality with respect to academic staff availability in the twin cities. The differences in close supervision of students by academic staff between public and private sector educational institutions were also analysed, and the results reflected a difference between private and public educational institutions with respect to close supervision of students. The results also highlighted the factors that are involved in higher performance of students in private institutes as compared to that of students in public institutes. These factors can be implemented in the public sector to increase student performance.

    Consumption of chicken meat has tremendously increased, especially in big cities of Pakistan like Lahore, during last few decades, due to low cholesterol level and lesser price as compared to beef and lamb meat. Non- scientific slaughter methods common in practice have increased the risk of bacterial load on chicken meat making it unsafe for human consumption. Keeping in view, the risk of bacterial contamination on chicken meat present study was conducted to determine bacterial load in different areas (Shad Bagh, Samanabad, Sanda) of city Lahore. Pour-plate method was used with differential media of blood agar, and selective medias of eosinmethylene blue, citrimide agar and mannitol agar. Maximum bacteria] growth (35.3 plus minus 0.77 million per gram) was observed in blood agar in Shad Bagh's poultry meat while in Samanabad's poultry meat maximum bacterial growth was observed in eosinmethylene blue agar (9.6 plus minus 0.40 million per gram) while Sanda's poultry meat showed maximum bacterial growth in cetrimide agar (6.9 plus minus 0.43).

    2008-10-01

    Full Text Available Urban heat islands are one of the most critical urban environment heat problems. Landsat ETM+ satellite data were used to investigate the land surface temperature and underlying surface indices such as NDVI and NDBI. A comparative study of the urban heat environment at different scales, times and locations was done to verify the heat island characteristics. Since remote sensing technology has limitations for dynamic flow analysis in the study of urban spaces, a CFD simulation was used to validate the improvement of the heat environment in a city by means of wind. CFD technology has its own shortcomings in parameter setting and verification, while RS technology is helpful to remedy this. The city of Wuhan and its climatological condition of being hot in summer and cold in winter were chosen to verify the comparative and combinative application of RS with CFD in studying the urban heat island.

    This study examined population mobility among residents of 5 cities in China: Wuhan, Beijing, Shanghai, Guangzhou, and Shenzhen. Data were obtained from the 1995 Sample Survey of 1% of Wuhan Population and provincial Statistical Yearbooks. The total mobile population in China has increased from 20-80 million during 1982-95. Shanghai is the largest Chinese city. Beijing has a large proportion of international and internal migrants. Guangzhou is a capital city that was the first to adopt economic reforms. Migration fueled development in Shenzhen. A larger mobile population was related to larger population density. The mobile population was 20% in all cities, 30% of central city population, and 140.5% of the central city of Shenzhen. Beijing and Shanghai had the highest growth rates. Construction accounts for the largest percentage of business-related mobile population in Wuhan, Beijing, and Shanghai. Manufacturing accounts for the largest percentage in Guangzhou and Shenzhen. Most of the mobile population in capital cities such as Wuhan and Guangzhou, originates from within the provinces. The largest percentage of mobile population in Beijing and Shanghai come from adjacent provinces. Guangzhou receives many migrants from adjacent Hong Kong, Macao, and Taiwan. 47.8-78.8% of mobile population were farmers. More migrants are men. Educational levels are low. The mobile population contributes to industry and informational/cultural exchange. The migrants detract from urban areas in population pressure on housing and services, shortages of employment, illegal activities and crime, and unplanned births.

    Full Text Available The first impressions that caused the changes made in Mexico City in its process of transformation into a modern city were captured by its poets drawing attention to different aspects of life in the capital. While from the popular poetry the record of the entrance of the electricity in the public road was left, from the official poetry was tried to witness the new cosmopolitan status of the Mexico City in the Porfirian era, through the fashion and the customs that were revealed in one of the main streets of the city. Comparing these poems allows us to know the initial strategies of poetic figuration of urban space that will continue to develop along different paths throughout the twentieth century until we reach our days.

    2018-03-01

    Full Text Available Several cities around the world are self-proclaimed "smart" by integrating, in varying degrees, new technologies in the different spheres of the city. Nevertheless, despite this effervescence around the smart city, the concept requires more conceptualization from the researchers. This is even more important when it comes time to distinguishing between smart city and smart destination. The relationship between these two concepts is blurred and the transition from the smart city to the smart destination is not automatic. This situation is explained by the fact that the intrinsic characteristics of their respective target populations, being the citizens and the tourists, are different. This article compares three Canadian cities in the province of Quebec with the aim of demonstrating that the realization of a smart destination project requires the adaptation of governance structure and the involvement of all the stakeholders and more particularly in tourism.

    Full Text Available Urban tourism has become a significant phenomenon of tourism over the last decade. the importance of urban tourism has grown mainly due to the development of transport and information technologies. rapid advancement of low cost airlines and reduction of administrative barriers owing to the expansion of the schengen area caused not only the development of a number of urban destinations, including Prague, but also the growth of new source markets. this paper compares the development of urban tourism in Prague with the situation in Vienna and Budapest in the last decade. the aim of the paper is to describe the main trends of tourism development and the geographic distribution of tourism in Prague in comparison with culturally and historically similar cities - Vienna and Budapest. the analysis shows high load of tourism in Prague and its strong concentration in the old city. this causes congestion in the city centre and an extrusion of residential functions by the functions of tourism. As a result, a tourism ghetto has been formed in the centre of Prague and the urban society has been increasingly dualized.

    Full Text Available City branding is not only increasingly practiced in cities in established economies, but also among municipal governments in countries, until quite recently, rather closed off from the outside world. One country with a strong drive to engage in urban (redevelopment in the post-oil era through enhancing its ‘ecological modernization’ is Iran. Megacities in Iran have all begun to venture into making profiles of what they think they are or would like to be. However, some of the adopted city branding strategies lack sophistication. In this article, the authors examine what indicators can be used for evaluating the credibility of city brands and apply these to Iran’s 15 megacities. After offering brief descriptions of the generic features of each of these cities, they map their use of city brand identities and popular city labels related to ecological modernization and analyze the credibility of their city branding practices. Based on their findings, the authors distinguish five types of cities and explain what makes some types more credible in their use of brands than others. Generally speaking, compared to cities in other nations, Iranian cities pay special attention to historical, natural, cultural, and religious aspects.

    Today's cities generate tremendous amounts of data, thanks to a boom in affordable smart devices and sensors. The resulting big data creates opportunities to develop diverse sets of context-aware services and systems, ensuring smart city services are optimized to the dynamic city environment. Critical resources in these smart cities will be more rapidly deployed to regions in need, and those regions predicted to have an imminent or prospective need. For example, crime data analytics may be used to optimize the distribution of police, medical, and emergency services. However, as smart city services become dependent on data, they also become susceptible to disruptions in data streams, such as data loss due to signal quality reduction or due to power loss during data collection. This paper presents a dynamic network model for improving service resilience to data loss. The network model identifies statistically significant shared temporal trends across multivariate spatiotemporal data streams and utilizes these trends to improve data prediction performance in the case of data loss. Dynamics also allow the system to respond to changes in the data streams such as the loss or addition of new information flows. The network model is demonstrated by city-based crime rates reported in Montgomery County, MD, USA. A resilient network is developed utilizing shared temporal trends between cities to provide improved crime rate prediction and robustness to data loss, compared with the use of single city-based auto-regression. A maximum improvement in performance of 7.8% for Silver Spring is found and an average improvement of 5.6% among cities with high crime rates. The model also correctly identifies all the optimal network connections, according to prediction error minimization. City-to-city distance is designated as a predictor of shared temporal trends in crime and weather is shown to be a strong predictor of crime in Montgomery County.

  8. Addressing Flooding and SuDS when Improving Drainage and Sewerage Systems—A Comparative Study of Selected Scandinavian Cities

    2014-04-01

    Full Text Available Pluvial flooding already challenges the capacity of drainage and sewerage system in urban areas in Scandinavia. For system owners this requires a stricter prioritization when improving the systems. Experts seem to agree that a regime shift from improving old combined sewers by piped solutions to more sustainable drainage systems (SuDS, must take place. In this paper results from an investigation amongst the largest cities in Norway, Denmark and Sweden concerning drivers and preferred methods for improving the old system are presented. The results indicate that Norway ranks flood prevention lower than the other Scandinavian countries. During the last decades, Norwegian authorities have had a strong focus on pollution from wastewater treatment plants (WWTP. The attention to drainage and sewerage system regarding flooding, water leaks, infiltration or pollution has been neglected. Renewal or rate of investment in relation to existing drainage and sewerage system is easy to register, and provides a measure of the activity. In order to optimize flood prevention, and may be promoting the use of SuDS, the cities should be required to measure the efficiency, either by monitoring or modeling the impact of stormwater to the system. Lack of such requirements from Norwegian authorities seem to be a plausible explanation to why Norwegian cities are less focused on flood prevention compared to Swedish and Danish cities.

  9. The Politics of City Regions in Comparative Perspective

    Full Text Available An age of the urban regionalism has arrived. Postindustrial capitalism is evolving in ways that give renewed importance to city regions. New forms of economic interdependence, the rise of specialized flexible production, the spread of new technologies, and other factors are making the city region a prominent node in today’s globalized economy. Although governments at all levels have been responding to manage this reality, political intervention remains a contentious matter because regional economic development has unleashed new political tensions over governance. Some tensions arise from economic obstacles to regional political cooperation. Other tensions arise from the urban political process in city regions. Many political interests, including entire governments, oppose political collaboration necessary for regional governance because it threatens them with loss of power, status or wealth. The political forces favoring resistance at the local and metropolitan levels tend to differ in the North American and Western European contexts, however.L’âge du «régionalisme urbain» est arrivé. Le capitalisme postindustriel se développe avec des modalités qui accordent une nouvelle importance aux villes-régions. De nouvelles formes d’interdépendance économique, l’émergence d’une production spécialisée flexible, la diffusion des nouvelles technologies, et d’autres facteurs font des villes-régions un nœud prédominant dans l’économie globalisée d’aujourd’hui. Bien que les gouvernements de tous niveaux aient fourni des réponses pour gérer cette réalité, l’intervention politique demeure un objet de conflit parce que le développement économique régional a libéré de nouvelles tensions politiques. Certaines tensions naissent des obstacles économiques à une coopération politique de niveau métropolitain. D’autres proviennent de l’intérieur même du processus politique des villes. De nombreux int

    Full Text Available Cities are characterised by local identities, which have been shaped by natural and cultural values. Constituting elements of local identity are settlement pattern bearing the traces of past, local music, traditional taste, handicrafts and life story. Besides, there has been a fast pace of life owing to globalization, and globally standardized cities, where local identities are ignored, have been emerged in planning-design-implementation process. From this viewpoint, Cittaslow movement has become a major turning point for liveable and sustainable cities that emphasize the local character. In this context, in the study, it is aimed to raise awareness about Cittaslow which is an example of an urban model for sustainability. In line with this purpose, the importance of Cittaslow approach and the criteria that are needed to be met for being a member of the Association of Cittaslow have been revealed. In line with these criteria Cittaslow cities in Turkey were discussed comparatively in terms of their features were considered. Examples from our country have been evaluated together with the international Cittaslow examples. In addition, proposals have been made by developing strategies in planning- designing and implementation process for the Cittaslow approach.

    Red brick and interlocking brick are the building materials that are often used for wall installation work on houses construction. In the development of building materials technology and cost savings, interlocking brick can be alternative to replace red bricks. In Aceh Province, the use of interlocking bricks is less popular compared to other big cities in Indonesia. Interlocking brick is made from a mixture of clay, concrete sand and compacted cement and one of the environmentally friendly materials because it does not burn the process like red brick material. It is named interlocking brick because the installation method is locked together and it serves as a structural and partition wall of residential buildings. The aims of this study are to compare the cost of building a house in Banda Aceh City using red brick and interlock brick building materials. The data were obtained from interviews and questionnaires distributed to respondents who had built houses in Banda Aceh City. The results concluded that the house construction cost using interlock brick offer lower construction cost at comparable quality rather than using red brick.

    Prevalence of schizophrenia and rates of first admission to hospital for this disorder are higher in most modern industrialised cities, and in urban compared with rural areas. The "geographical drift" hypothesis (ie, most schizophrenics tend to drift into city areas because of their illness or its prodrome) has remained largely unchallenged. We have investigated the association between place of upbringing and the incidence of schizophrenia with data from a cohort of 49,191 male Swedish conscripts linked to the Swedish National Register of Psychiatric Care. The incidence of schizophrenia was 1.65 times higher (95% confidence interval 1.19-2.28) among men brought up in cities than in those who had had a rural upbringing. The association persisted despite adjustment for other factors associated with city life such as cannabis use, parental divorce, and family history of psychiatric disorder. This finding cannot be explained by the widely held notion that people with schizophrenia drift into cities at the beginning of their illness. We conclude that undetermined environmental factors found in cities increase the risk of schizophrenia.

Twitter offers organizations fast and effective way to monitor the users’ feelings towards their mood in the cities. In twitter there are the big information data that be able to download freely, this study collected data from twitter and make the classification based on users’ tweets to categorize the index of happiness of the city. The urban structure data are collected from the urban guideline development from each city. The index of happiness becomes the prosperity level paradigm of a city, it becomes a tool to assess and compare how the city is liveable. This study will analyse from the users’ tweets on a regular basis in three cities of Indonesia, to the parameters of happiness that will be compared with the urban structure development. Based on data of the index of happiness from social media can offer better information for city planners and developers that can be used to improve planning and quality of life in the city and future of urban development.

    In urban environments, green roofs provide a number of benefits, including decreased urban heat island effects and reduced energy costs for buildings. However, little research has been done on the non-plant biota associated with green roofs, which likely affect their functionality. For the current study, we evaluated whether or not green roofs planted with two native plant communities in New York City functioned as habitats for soil fungal communities, and compared fungal communities in green roof growing media to soil microbial composition in five city parks, including Central Park and the High Line. Ten replicate roofs were sampled one year after planting; three of these roofs were more intensively sampled and compared to nearby city parks. Using Illumina sequencing of the fungal ITS region we found that green roofs supported a diverse fungal community, with numerous taxa belonging to fungal groups capable of surviving in disturbed and polluted habitats. Across roofs, there was significant biogeographical clustering of fungal communities, indicating that community assembly of roof microbes across the greater New York City area is locally variable. Green roof fungal communities were compositionally distinct from city parks and only 54% of the green roof taxa were also found in the park soils. Phospholipid fatty acid analysis revealed that park soils had greater microbial biomass and higher bacterial to fungal ratios than green roof substrates. City park soils were also more enriched with heavy metals, had lower pH, and lower quantities of total bases (Ca, K, and Mg) compared to green roof substrates. While fungal communities were compositionally distinct across green roofs, they did not differentiate by plant community. Together, these results suggest that fungi living in the growing medium of green roofs may be an underestimated component of these biotic systems functioning to support some of the valued ecological services of green roofs.

City park soils were also more enriched with heavy metals, had lower pH, and lower quantities of total bases (Ca, K, and Mg compared to green roof substrates. While fungal communities were compositionally distinct across green roofs, they did not differentiate by plant community. Together, these results suggest that fungi living in the growing medium of green roofs may be an underestimated component of these biotic systems functioning to support some of the valued ecological services of green roofs.

    Full Text Available Sassanid replaced migrating nomads and tribes with urbanization system and concentration of population. Sassanid desire to increase the population was due to the fact that population is the core of urban systems and focus-oriented system. Sassanid tried marching to Syria and Asia Minor to gain population. Immigrant Roman population was accommodated in newly established cities. Romans had structured and deep thinking about urban development, such that their territory was made up of urban units which were connected through a system of roads and bridges. Romans innovation in urban development can be summed up in creating military cities. Sassanid urbanization after the Parthians was influenced by Roman urbanization which is most visible in the shape of Sassanid cities. In this study, while examining cities and urbanization in Sassanid reign and Roman Empire, their influence on each other and their similarities and differences in their urbanization methods were also investigated.

  3. [The monster and the city].

    1996-01-01

    "Negative aesthetic categories" and, specifically, the idea of monsters and monstrosity, are used in this discussion of urban phenomena and their relation to modern art. The reflection on monstrosity as a metaphor for the city draws upon such disparate sources as Greek philosophers, Freudian theory, and recent art criticism. It compares dictionary definitions of monster to a general concept of cities, judging the modern metropolis to be "excessively large or extraordinary," "disfigured and ugly," and even "cruel" and "perverse" as demonstrated in social pathologies such as terrorism that breed in cities. The relationship between monstrosity and the city is evident in a variety of artistic manifestations and can be seen in the work of planners, architects, and artists. The examination opens up promising areas for future research in greater depth.

    Consumers and organizations worldwide are searching for low-carbon alternatives to conventional gasoline and diesel vehicles to reduce greenhouse gas (GHG) emissions and their impact on the environment. A comprehensive technique used to estimate overall cost and environmental impact of vehicles is known as life cycle assessment (LCA). In this article, a comparative LCA of diesel and compressed natural gas (CNG) powered heavy duty refuse collection vehicles (RCVs) is conducted. The analysis utilizes real-time operational data obtained from the City of Surrey in British Columbia, Canada. The impact of the two alternative vehicles is assessed from various points in their life. No net gain in energy use is found when a diesel powered RCV is replaced by a CNG powered RCV. However, significant reductions (approximately 24% CO 2 -equivalent) in GHG and criteria air contaminant (CAC) emissions are obtained. Moreover, fuel cost estimations based on 2011 price levels and a 5-year lifetime for both RCVs reveal that considerable cost savings may be achieved by switching to CNG vehicles. Thus, CNG RCVs are not only favorable in terms of reduced climate change impact but also cost effective compared to conventional diesel RCVs, and provide a viable and realistic near-term strategy for cities and municipalities to reduce GHG emissions. - Highlights: ► Life cycle analysis is performed on two alternative refuse collection vehicle technologies. ► Real-time operational data obtained by the City of Surrey in British Columbia are utilized. ► The life cycle energy use is similar for diesel and CNG RCVs. ► A 24% reduction of GHG emissions (CO 2 -equivalent) may be realized by switching from diesel to CNG. ► CNG RCVs are estimated to be cost effective and may lead to reduced fuel costs.

    Full Text Available The article considers relations between the city of Irkutsk and Lake Baikal in terms of cultural geography. Baikal is included in the UNESCO world heritage list. Unlike the majority of lakes also included in this list, Baikal’s coast is inhabited, especially its southern part. Similar situation is, for example, in the cluster “the city of Bergen – Geiranger village – Geirangerfjord” in Norway. The comparative analysis shows how Norway’s positive experience of the system “a city – a village – a natural phenomenon” could be used in order to make Irkutsk more attractive for tourists and citizens.

    To determine and compare the relevance of Piaget's cognitive principles among 4- to 7-year-old parented and orphan children in Belagavi City, Karnataka, India. This study was conducted on 240 children between the ages of 4 to 7 years who were equally divided into two groups of 120 parented and 120 orphan children. These were subdivided into four groups of 30 children each. Various characteristics like egocentrism, concept of cardinal numbers based on centration, lack of conservation, and reversibility were assessed, using experiments and comparison of their prevalence between two groups was carried out. There is a statistically significant difference in the cognitive development among parented and orphan children age 4 to 7 years. There is a significantly better cognitive development among parented children as compared with orphan children in Belagavi city. A child is not a miniature adult but rather can think and perceive the world differently from an adult. Understanding a child's intellectual level can enable a pedodontist to deliver improved quality care to children. According to Jean Piaget, in the preoperational period, children think symbolically and their reasoning is based more on appearance rather than logic. It is often rightly said that a child's behavior is a reflection of his parents. However, Piaget did not consider the effect of social setting and culture on the cognitive development. This study was carried out as there is not much literature available to describe the cognitive development of children in the Indian scenario and the influence of parental presence on the same.

  13. The Usage and Perception of Pedestrian Zones in Lithuanian Cities: Multiple Criteria and Comparative Analysis

    Directory of Open Access Journals (Sweden)

    Rūta Dičiūnaitė-Rauktienė

    2018-03-01

    Full Text Available As pedestrian zones are public spaces in urban areas, they are important in terms of meeting people’s needs. However, it is worth noting that attention should be paid not only to the development of the physical infrastructure, but also to a sustainable balance between the socio-economic and environmental aspects. To guide urban planning and management initiatives towards more sustainable patterns, it is essential to re-examine the already existing characteristics of cities, establishing how they are used and perceived by inhabitants. The present research suggests environmental, economic and social criteria that determine a greater vitality of pedestrian zones in cities and better life quality for the inhabitants. A questionnaire survey was used to assess common attitudes regarding the research topic in major cities in Lithuania. The multiple criteria decision-making COPRAS (COmplex PRoportional ASsessment method was used for the formation of a priority queue. The research results showed the attitudes of inhabitants towards pedestrian zones in Vilnius, Kaunas and Klaipėda. The inhabitants of these three cities regarded social and environmental criteria groups as the most significant. Contrary to what was expected and anticipated, respondents do not consider economic criteria as playing a key role in the sustainable preservation and development of pedestrian zones.

    Gröger, Gerhard; Plümer, Lutz

    2012-07-01

    CityGML is the international standard of the Open Geospatial Consortium (OGC) for the representation and exchange of 3D city models. It defines the three-dimensional geometry, topology, semantics and appearance of the most relevant topographic objects in urban or regional contexts. These definitions are provided in different, well-defined Levels-of-Detail (multiresolution model). The focus of CityGML is on the semantical aspects of 3D city models, its structures, taxonomies and aggregations, allowing users to employ virtual 3D city models for advanced analysis and visualization tasks in a variety of application domains such as urban planning, indoor/outdoor pedestrian navigation, environmental simulations, cultural heritage, or facility management. This is in contrast to purely geometrical/graphical models such as KML, VRML, or X3D, which do not provide sufficient semantics. CityGML is based on the Geography Markup Language (GML), which provides a standardized geometry model. Due to this model and its well-defined semantics and structures, CityGML facilitates interoperable data exchange in the context of geo web services and spatial data infrastructures. Since its standardization in 2008, CityGML has become used on a worldwide scale: tools from notable companies in the geospatial field provide CityGML interfaces. Many applications and projects use this standard. CityGML is also having a strong impact on science: numerous approaches use CityGML, particularly its semantics, for disaster management, emergency responses, or energy-related applications as well as for visualizations, or they contribute to CityGML, improving its consistency and validity, or use CityGML, particularly its different Levels-of-Detail, as a source or target for generalizations. This paper gives an overview of CityGML, its underlying concepts, its Levels-of-Detail, how to extend it, its applications, its likely future development, and the role it plays in scientific research.

    2017-10-01

    The city waste is one of the main urban problems to be solved, since they generate large impacts on the environment, like use of land, contamination of the soil, water and air, and human diseases, among others. In Rosario city, placed in the Argentina Humid Pampa and having about 1 million inhabitants, the Municipality is developing different strategies in order to reduce the waste impact (295 000 Tons in 2016). One of the most important actions was the construction of the Bella Vista compost plant in 2012 (within the largest in South America). In the present work we analysed the possibility to use urban organic waste (that for Rosario city represents about 58% of the total waste in the last years) for: a) compost production and b) biogas production, with compost as a by-product. We determined the produced compost and biogas and the corresponding greenhouse gases (GHG) emissions, considering three possible scenarios: A reference scenario (Sr ) where 24 100 Tons of urban solid waste per year is transported from the city houses and buildings to a transfer landfill and then to the a final disposal landfill; a scenario number one (S1 ) in which the same fraction of waste is transported to the Compost plant and transformed to compost and a scenario number two (S2 ) where the same quantity of waste is used for the production of biogas (and compost). Applying the IPCC 2006 Model, we compare the results of the annual GHG emissions, in order to select the best alternative: to expand the Compost plant or to build a Biogas (plus compost) plant. We also discussed the extension of the present analysis to the situation in which all the capability of the Compost plant (25% of the 2016 waste production of the city) is used and the impact these plants are having for a better quality of life of persons involved in the informal waste activity.

    The climate of a region is an environmental resource with important implications for things such as thermal comfort, health and productivity of the population. In this work, the bioclimatic comfort was evaluated for seven seasonally warm/hot cities of Mexico by means of the following current indexes: Discomfort Index, Enthalpy Index and Heat Strain Index. Also, the periods during which it is necessary to use air conditioning in the studied cities were calculated from estimated global radiation and hourly data of temperature and relative humidity which made it possible to establish them with high precision. Finally, the useful of the Heat Strain Index is shown. It is a simple index needing available meteorological data to compare bioclimatic conditions of similar sites. [Spanish] El clima regional tiene implicaciones en el confort, la salud y la productividad de la poblacion. En este articulo se presentan las evaluaciones bioclimaticas comparativas de siete ciudades calidas de Mexico. Se aplicaron los indices bioclimaticos de disconfort, entalpia y esfuerzo frente al calor. Se calcularon los periodos para los cuales es necesario el uso de aire acondicionado, a partir de estimaciones de radiacion solar global y de temperatura y humedad horarias medias mensuales. Finalmente se muestra la utilidad y calidad del Indice de esfuerzo frente al calor, el cual requiere solo de datos climatologicos comunes para poder comparar condiciones bioclimaticas de sitios similares.

    Inhabitants of rural areas can be tempted to migrate to urban areas for the type and range of facilities available. Although urban inhabitants may benefit from greater access to human and social services, living in a big city can also bring disadvantages to some residents due to changes in social and physical environments. We analysed data from 4,208 women aged >15 years old participating in the fourth wave of the Indonesia Family Life Survey. Chronic condition risk factors - systolic and diastolic blood pressure (SBP and DBP), body mass index (BMI), and tobacco use - among women in four major cities in Indonesia (Jakarta, Surabaya, Medan, and Bandung) were compared against other cities. Fractional polynomial regression models were applied to examine the association between living in the major cities and SBP, DBP, BMI, and tobacco use. The models were also adjusted for age, education, employment status, migration status, ethnic groups, and religion. The patterns of SBP, DBP, and BMI were plotted and contrasted between groups of cities. Chronic condition prevalence was higher for women in major cities than in contrasting cities (p<0.005). Living in major cities increased the risk of having higher SBP, DBP, BMI and being a current smoker. Chronic disease risk factors in major cities were evident from younger ages. Women residing in Indonesia's major cities have a higher risk of developing chronic conditions, starting at younger ages. The findings highlight the challenges inherent in providing long-term healthcare with its associated cost within major Indonesian cities and the importance of chronic disease prevention programmes targeting women at an early age.

    Understanding emissions from cities is increasingly important as a growing fraction of the world's population moves to cities. Here we use a novel technology, dual frequency comb spectroscopy, to measure city emissions using a long outdoor open path. We simultaneously measured CO2, CH4, and H2O over the city of Boulder, Colorado and over a clean-air reference path for two months in the fall of 2016. Because of the spatial coverage of our measurements, the layout of the city and power plant locations, and the predominant wind direction, our measurements primarily pick up vehicle emissions. We choose two days with consistent CO2 enhancements over the city relative to the reference path and use a simple 0-D box model to calculate city emissions for these days. We scale these up to annual emissions and compare our measurements with the City of Boulder bottom-up vehicle emissions inventory based on total vehicle miles traveled, fuel efficiency, and vehicle type distribution. We find good agreement (within about a factor of two) between our top-down measurements and the city's bottom-up inventory value.

  2. Ecology for the shrinking city (JA) | Science Inventory | US ...

    Science.gov (United States)

    This article brings together the concepts of shrinking cities—the hundreds of cities worldwide experiencing long-term population loss—and ecology for the city. Ecology for the city is the application of a social–ecological understanding to shaping urban form and function along sustainable trajectories. Ecology for the shrinking city therefore acknowledges that urban transformations to sustainable trajectories may be quite different in shrinking cities as compared with growing cities. Shrinking cities are well poised for transformations, because shrinking is perceived as a crisis and can mobilize the social capacity to change. Ecology is particularly well suited to contribute solutions because of the extent of vacant land in shrinking cities that can be leveraged for ecosystem-services provisioning. A crucial role of an ecology for the shrinking city is identifying innovative pathways that create locally desired amenities that provide ecosystem services and contribute to urban sustainability at multiple scales. This paper brings together the concepts of ecology for the city and shrinking cities – the hundreds of cities worldwide experiencing long-term population loss. Ecology for the city is the application of social-ecological understanding to shaping urban form and function along sustainable trajectories.

    An urban heat island (UHI) is a climate phenomenon that results in an increased air temperature in cities when compared to their rural surroundings. In this Letter, the dependence of an UHI on urban geometry is studied. Multiyear urban-rural temperature differences and building footprints data combined with a heat radiation scaling model are used to demonstrate for more than 50 cities worldwide that city texture—measured by a building distribution function and the sky view factor—explains city-to-city variations in nocturnal UHIs. Our results show a strong correlation between nocturnal UHIs and the city texture.

    This book addresses the topic of playable cities, which use the ‘smartness’ of digital cities to offer their citizens playful events and activities. The contributions presented here examine various aspects of playable cities, including developments in pervasive and urban games, the use of urban data to design games and playful applications, architecture design and playability, and mischief and humor in playable cities. The smartness of digital cities can be found in the sensors and actuators that are embedded in their environment. This smartness allows them to monitor, anticipate and support our activities and increases the efficiency of the cities and our activities. These urban smart technologies can offer citizens playful interactions with streets, buildings, street furniture, traffic, public art and entertainment, large public displays and public events.

  9. Influence of exposure differences on city-to-city heterogeneity ...

    Science.gov (United States)

    Multi-city population-based epidemiological studies have observed heterogeneity between city-specific fine particulate matter (PM2.5)-mortality effect estimates. These studies typically use ambient monitoring data as a surrogate for exposure leading to potential exposure misclassification. The level of exposure misclassification can differ by city affecting the observed health effect estimate. The objective of this analysis is to evaluate whether previously developed residential infiltration-based city clusters can explain city-to-city heterogeneity in PM2.5 mortality risk estimates. In a prior paper 94 cities were clustered based on residential infiltration factors (e.g. home age/size, prevalence of air conditioning (AC)), resulting in 5 clusters. For this analysis, the association between PM2.5 and all-cause mortality was first determined in 77 cities across the United States for 2001–2005. Next, a second stage analysis was conducted evaluating the influence of cluster assignment on heterogeneity in the risk estimates. Associations between a 2-day (lag 0–1 days) moving average of PM2.5 concentrations and non-accidental mortality were determined for each city. Estimated effects ranged from −3.2 to 5.1% with a pooled estimate of 0.33% (95% CI: 0.13, 0.53) increase in mortality per 10 μg/m3 increase in PM2.5. The second stage analysis determined that cluster assignment was marginally significant in explaining the city-to-city heterogeneity. The health effe

    The concept of a livable smart city presented in this book highlights the relevance of the functionality and integrated resilience of viable cities of the future. It critically examines the progressive digitalization that is taking place and identifies the revolutionized energy sector as the basis of urban life. The concept is based on people and their natural environment, resulting in a broader definition of sustainability and an expanded product theory. Smart City 2.0 offers its residents many opportunities and is an attractive future market for innovative products and services. However, it presents numerous challenges for stakeholders and product developers.

  13. Universities scale like cities.

    Directory of Open Access Journals (Sweden)

    Anthony F J van Raan

    Full Text Available Recent studies of urban scaling show that important socioeconomic city characteristics such as wealth and innovation capacity exhibit a nonlinear, particularly a power law scaling with population size. These nonlinear effects are common to all cities, with similar power law exponents. These findings mean that the larger the city, the more disproportionally they are places of wealth and innovation. Local properties of cities cause a deviation from the expected behavior as predicted by the power law scaling. In this paper we demonstrate that universities show a similar behavior as cities in the distribution of the 'gross university income' in terms of total number of citations over 'size' in terms of total number of publications. Moreover, the power law exponents for university scaling are comparable to those for urban scaling. We find that deviations from the expected behavior can indeed be explained by specific local properties of universities, particularly the field-specific composition of a university, and its quality in terms of field-normalized citation impact. By studying both the set of the 500 largest universities worldwide and a specific subset of these 500 universities--the top-100 European universities--we are also able to distinguish between properties of universities with as well as without selection of one specific local property, the quality of a university in terms of its average field-normalized citation impact. It also reveals an interesting observation concerning the working of a crucial property in networked systems, preferential attachment.

  17. Impact of Location of the Central Activities on Development of Open Public Space in the City Centers of Small Cities

    Full Text Available Urban areas of the central activities with mixed land use are crucial for the development of city center, even in small cities. In the last decades or two the attention is drawn on the retail and service activities that are usually located outside of cities near main roads. Municipalities had already detected this problem, but they are not implementing any of the measures (Rebernik, 2010. The purpose of this paper is to demonstrate that the central activities in small cities in Slovenia are located in freestanding buildings, which is most appropriate in terms of forming the open public space in the city center. In this research we compared ten central activities (Vrišer, 1988, 1990, Kokole, 1971 in 34 small cities. We selected only those small cities (Prosen et al, 2008 which have among other activities a county court. The results showed the differences and commonalities of the central activities in selected small cities according to the indicators. Litija, Domžale and Sevnica are small cities, where activities that could articulate open public space are located in the larger building complexes. The phenomenon is similar to a modern machine, where action in it and indirectly the insight into the functioning of the society is invisible to the observer (Kos, 2008. We found out that in these tree cities the central activities are not forming the open public spaces in front of the public buildings (Vertelj Nared, 2014. The result is problematic image of the city and changed forces of the city life.

A cross-sectional study among 17,000 prisoners at 4 Mexico City prisons (June to December 2010). Participation was voluntary, confidential and based on informed consent. Participants were tested for HIV, Hepatitis B & C, syphilis, hypertension, obesity, and, if at risk, glucose and cholesterol. A subset completed a questionnaire on socio-demographic characteristics and risk behaviors. Positive results were delivered with counseling and treatment or referral. 76.8% (15,517/20,196) of men and 92.9% (1,779/1,914) of women participated. Complete data sets were available for 98.8%. The following prevalence data were established for transmissible infections: HIV 0.7%; syphilis: Anti-TP+/VDRL+ 2.0%; Hepatitis B: HBcAb 2.8%, HBsAg 0.15%; Anti-HCV 3.2%. Obesity: 9.5% men, 33.8% women. Compared with national age- and sex-matched data, the relative prevalence was greater for HIV and syphilis among women, HIV and Hepatitis C in men, and all infections in younger participants. Obesity prevalence was similar for women and lower among male participants. The prevalence of previously diagnosed diabetes and hypertension was lower. Questionnaire data (1,934 men, 520 women) demonstrated lower educational levels, increased smoking and substance use compared to national data. High levels of non-sterile tattooing, physical abuse and histories of sexual violence were found. The study identified that health screening is acceptable to Mexico City prisoners and feasible on a large-scale. It demonstrated higher prevalence of HIV and other infections compared to national data, though low rates compared to international data.

    The city has proved to be the most successful form of human agglomeration and provides wide employment opportunities for its dwellers. As advances in robotics and artificial intelligence revive concerns about the impact of automation on jobs, a question looms: how will automation affect employment in cities? Here, we provide a comparative picture of the impact of automation across US urban areas. Small cities will undertake greater adjustments, such as worker displacement and job content substitutions. We demonstrate that large cities exhibit increased occupational and skill specialization due to increased abundance of managerial and technical professions. These occupations are not easily automatable, and, thus, reduce the potential impact of automation in large cities. Our results pass several robustness checks including potential errors in the estimation of occupational automation and subsampling of occupations. Our study provides the first empirical law connecting two societal forces: urban agglomeration and automation's impact on employment. PMID:29436514

  3. Nuclear methods used to compare air pollution in a city and a pollution-free area

    International Nuclear Information System (INIS)

    Shani, G.; Haccoun, A.

    1976-01-01

    A comparison study was made between city pollution and open-area pollution in order to be able to distinguish between air pollution whose source is urban activity (i.e. industry, transportation, etc.) and that in an area free of man's activities. The comparison was made between Beersheba, a city in the south of Isreal, and a spot in the desert, 40 km south of the city. The meteorological conditions at the two places are the same, and it is reasonable to assume that the background pollution (the dust that covers the area), is the same in both places. Neutron activation analysis was used for pollution detection; it is clear that certain elements cannot be detected by this means, though they may be known to exist in the air; hence, certain trace elements of the dust could be detected, but not, for example, the major components such as Ca and Si. The results are classified as typical urban pollutants and non-urban pollutants. Weather condition dependence was also investigated. The major source of urban pollution in Beersheba is bromine, which exists in the air in large quantities. The other urban pollutants are Zn, Cr, and Sb; these elements are found mainly in the city, in smaller quantities than bromine. The concentration of these elements is greatly reduced at night due to cessation of work in industry and reduced vehicular movement. The effect of weather and a seasonal dependence are clearly indicated (e.g. when the wind velocity increases and its direction is from the east, pollution in Beersheba rises). At the end of the winter the air is clearer than at the end of the summer. (author)

    Directory of Open Access Journals (Sweden)

    Michelangelo Russo

    2014-05-01

    Full Text Available The port is a strategic area of transition, where it is possible to perceive the territory-landscape and the urban front. However it lost its urban character, gradually becoming an high specialized independent machines, a sectorial infrastructure divided from the city: this phenomenon has created increasingly socio-economical marginalization.  Within a double view, lengthwise and transverse, we can describe the port as a space closed to the city and as an unfathomable barrier for the transverse flows that previously connected the waterfront to the city. The paper examines the case study of Naples, where the port expansion continues to grow without any integration with other parts of the city, distorting its “urban area” role, establishing its independence and making urban system compatibility conditions even weaker. The functional and physical division increases the perception of the port as a barrier rather than a filter. Turning the sense of these conditions aims at rethinking waterfront as a public space, a place where integration and specialization spaces become new open and accessible spatial devices. In some contemporary European and American cities (Aalborg, Oslo and Toronto we could see the port as multifunctional system, an interdisciplinary project that creates urban spaces integrated to the city and that allows the coexistence of different uses. The project of a new public space between the sea and the hinterland could involve all these conflicting functions creating, with different strategies, a potential multifunctional landscape. In Naples as well, where the waterfront is still waiting to be re-connected with the story of the city itself.

    Serui City in Papua Province has many unique characters and must be maintained for the sake of the continuity of its identity. However, this city still lacks the facility and depend on other areas. Accordingly, it becomes vulnerable. The wholeness of the city is not just by having strong character but also having strength regarding vitality. The loss of it can affect the character and even eliminate it. Cities and people have many similarities regarding character and vitality. Therefore, there is a chance to solve the problems in the city using the similar approach to treat the human. We called city personification methods as problem-solving to the city. It means that we treat the city as a human being so that the problem can be solved as the human’s treatment. The personification of this city is conducted because of the many treatments that have proven effective in humans and may also be powerful to manifest in city. The personification makes the design will only focus on the particular networks and not on the whole “body,” remain in the hope for strengthening (maintain and improve) the quality of wholeness (character and vitality) city which in this case is Serui.

  8. Branding Cities, Changing Societies

    DEFF Research Database (Denmark)

    Ooi, Can-Seng

    Societal changes are seldom discussed in the literature on city branding. The time element is important because it highlights the fluctuating reality of society. The city brand message freezes the place but in fact, the city branding exercise is a continuous process. Society emerges too. City...... brands are supposed to accentuate the uniqueness of the city, be built from the bottom-up and reflect the city's identity. This paper highlights three paradoxes, pointing out that city branding processes can also make cities more alike, bring about societal changes and forge new city identities. A city...... branding campaign does not just present the city, it may change the city. The relationships between the branding exercise and the city are intertwined in the evolution of the place....

    Smart cities present a substantial growth opportunity in the coming years. The role of GIS in the smart city ecosystem is to integrate different data acquired by sensors in real time and provide better decisions, more efficiency and improved collaboration. Semantically enriched vision of GIS will help evolve smart cities into tomorrow's much smarter cities since geospatial/location data and applications may be recognized as a key ingredient of smart city vision. However, it is need for the Geospatial Information communities to debate on "Is 3D Web and mobile GIS technology ready for smart cities?"

    Municipal solid waste (MSW) management is still an issue in many cities in Indonesia including Medan. Understanding the waste generation, its characteristic and communities involvement could provide effective solid waste management. This research compares waste generation from people who live in the city center and suburban area. The research also examines the willingness and participation of community about environmental aspect, especially solid waste management. The method of waste generation used Indonesian Nasional Standard 19-3964-1994. The city center generates 0.295 kg/person/day of solid waste and 0.180 kg/person/day for suburbs. The result showed that there are the common amount of waste compositions between the city center and suburban area. The majority waste composition was an organic fraction. Questionnaires were distributed to examine the community awareness. The descriptive statistic used to analyze the data. The result showed that people living in the city center are slightly higher in community awareness than in the suburb. This paper highlights that area of living could give some effect to solid waste generation, waste composition and rate of awareness.

  12. Population-Area Relationship for Medieval European Cities.

    Directory of Open Access Journals (Sweden)

    Rudolf Cesaretti

    Full Text Available Medieval European urbanization presents a line of continuity between earlier cities and modern European urban systems. Yet, many of the spatial, political and economic features of medieval European cities were particular to the Middle Ages, and subsequently changed over the Early Modern Period and Industrial Revolution. There is a long tradition of demographic studies estimating the population sizes of medieval European cities, and comparative analyses of these data have shed much light on the long-term evolution of urban systems. However, the next step-to systematically relate the population size of these cities to their spatial and socioeconomic characteristics-has seldom been taken. This raises a series of interesting questions, as both modern and ancient cities have been observed to obey area-population relationships predicted by settlement scaling theory. To address these questions, we analyze a new dataset for the settled area and population of 173 European cities from the early fourteenth century to determine the relationship between population and settled area. To interpret this data, we develop two related models that lead to differing predictions regarding the quantitative form of the population-area relationship, depending on the level of social mixing present in these cities. Our empirical estimates of model parameters show a strong densification of cities with city population size, consistent with patterns in contemporary cities. Although social life in medieval Europe was orchestrated by hierarchical institutions (e.g., guilds, church, municipal organizations, our results show no statistically significant influence of these institutions on agglomeration effects. The similarities between the empirical patterns of settlement relating area to population observed here support the hypothesis that cities throughout history share common principles of organization that self-consistently relate their socioeconomic networks to structured

    Full Text Available The article is aimed at carrying out a comparative analysis of different approaches to the definition of concepts of «smart city» and «smart sustainable city», as well as formalizing these concepts for their implementation, which will potentially contribute to spreading of both the concept and the national practice of sustainable urban development, including the economic, environmental, and general justice issues. The main reasons connected with the key role of cities in the social and economic aspects of people’s life over the world and the enormous influence on the ecological stability are considered; the main current scientific sources concerned with the research on «smart» cities are covered, and their comparative analysis is carried out. The definitions of other alternative concepts such as «digital» city, «intellectual» city, «virtual» city, etc., representing more concrete and less inclusive levels of development of city, are considered in detail and presented. The differences between the concept of «smart city» and other related terms in three categories are discussed. A detailed analysis of different keywords from different sources is carried out. Based on the carried out analysis, six primary categories have been identified: smart life, smart people, smart environment and sustainability, smart management, smart mobility and smart economy, which are important for understanding the essence of «smart» sustainable city.

    Arafah, Y.; Winarso, H.; Suroso, D. S. A.

    2018-05-01

    This paper aims to compare five smart city models selected based on a number of specific criteria. Following the comparison and assessment performed, we draw conclusions and further linkages identifying the components and characters found in resilient cities. The purpose of this analysis is to produce a new approach and concept: the “smart and resilient city.” Through in-depth literature study, this paper analyzes five conceptual smart city models deemed to have a background, point of view, and benchmark towards software group, as they focus on welfare, inclusion, social equality, and competitiveness. Analyzing the strategies, methods, and techniques of five smart city models, this paper concludes that there has been no inclusion of resilience concepts in the assessment, especially in the context of natural disasters. Basically, the models are also interrelated and there are some things that overlap. As a recommendation, there is a model that tries to combine the components and character of smart city and resilient city into one entity that is embedded as a whole in a conceptual picture towards the new concept, the “smart and resilient city”. The concept of smart city and resilient city go hand in hand with each other and thus are interrelated. Therefore, it is imperative to study that concept deeper, in this case primarily in the context of disaster.

    Full Text Available We are grateful to our many colleagues who took the time to respond to our analysis of Shanghai’s declining “avoidable mortality.”1 The range of their perspectives across 5 recent commentaries reassures us that the topic is worthy of sustained study. Indeed, the presumption behind our comparative research on healthcare in world cities 2 is that the city is a strategic unit of analysis for understanding the health sector and that world cities share a host of important characteristics. Contrary to Cheng’s 3 comment that we compared“disparate cities whose only common characteristic is that they are of mega-size,” we have relied on a “most similar systems” approach to comparative analysis.4 World cities are characterized by high population size and density, similar commuting patterns between their outer rings and urban cores, and similar functions in the realms of international finance, culture, media, and provision of tertiary and quaternary medical care. Likewise, they exhibit flagrant socioeconomic inequalities, share many of the same strengths and weaknesses, but exist within nations with strikingly different health policies.

  20. Medan City: Informality and the Historical Global City

    As projected by UN that two-thirds of Indonesia’s population will live in urban areas by 2050, rapid urbanization is happening in Indonesian cities. Initial research on eight Indonesian Cities (which includes Medan, Jatinegara, Bandung, Surakarta, Yogyakarta, Surabaya, Balikpapan, and Manado) by Tunas Nusa Foundation since 2012 shows that urbanization of each city has happened throughout history creating cultural, economic, and environmental networks that are distinct from one city to another. While the networks remain until today and continuously shapes the urban agglomeration pattern, not all parts of the city could undergo subsequent development that confirms the existing pattern, leading to the creation informality. Nor could it make future planning that comprehends the nature of its integrated urban dynamic beyond its current administrative authority. In this paper, we would like to share our study for Medan, North Sumatra as it shows a portrait of a city with a long relationship to a global network since the Maritime trade era. Medan has become home to many ethnic groups which have sailed and migrated as part of a global economic agenda creating a strong economic network between port cities along the Malacca Strait. The city has kept its role in the global economic network until today, to name a few, becoming the frontier for the Indonesia-Malaysia-Thailand Growth Triangle. While we celebrate Medan’s potential to become a global city with major infrastructure development as well as cultural assets as its advantage in the future, we argue that microscale cohesion supported by government policy in agreed planning documents are fundamental for the city to thrive amidst the challenges it is facing. Yet, these cultural assets, as well as micro scale cohesion in Medan City today, are still undermined. Thus, informality in Medan exists as result of ignorance and marginalization of certain socio-cultural groups, abandoning places and identity, as well as the

    the contemporary city and maybe the understanding of the city needs to be updated in some areas, before we are able to do so. In this paper, the focus will be directed towards two themes which become present with the Shrinking Cities phenomenon and therefore seems important to discuss in order to understand...... the concept of Shrinking Cities. These two themes may affect the understanding of the existing city theory. The first theme is concerned with the physical understanding of the city where the traditional assumption about the city as a high density area, with buildings as the dominant structure, is questioned....... Here the concept of the city as an urban landscape will be introduced. The second theme points to the need for a discussion regarding the object of our planning when developing the cities. Previously, the purpose of city development has been growth and expansion, but with the Shrinking Cities...

    This paper aims to analyse the evolution experienced by the neighbourhoods that comprise the so-called first periphery. Most of them have been thoroughly studied, has led to recognize theirs values and to be included in the catalogues of heritage protection of their respective cities. However, this research shows that is pending an in-depth analysis in cities of intermediate scale. Its significance lies not only in the fact that they are the most significant operations of architecture of the modern movement in their respective cities, but are especially noteworthy the values derived from its strategic location within the urban structure of these intermediate scale cities. Being near to city centre, they have been constituted as transition pieces between historic sites, new peripheral developments, and even, their nearest territory. As method, this research proposes a comparative analysis of traceability among different study cases, from medium-sized cities of the Andalusian Coast (Spain). In this context, it means recording the evolution that these promotions have been experienced since their first designs until their current situation. It attempts to find the characteristics that have resulted in the urban configuration of this periphery and to recognize the sum of all the cultural, economic, social and technological aspects that conditions the ways of life that today are detected in them. Definitely, the knowledge generated by this research allows extracting architectural and urban values of these examples, which justify its necessary dissemination as part of our legacy.

  4. Primacy analysis in the system of Bulgarian cities

    The concept of "primacy" as introduced by Jefferson in 1939 in urban geography leads to the notion of "dominant city" also known as the primate city. Practically, the notion was extended by Sheppard in view of discussing some "hierarchy". The type of dominance is not universal nor any hierarchy reversal. Both can be time and sample dependent. Thus, as an example taking into consideration the existence of both pieces of the puzzle, we consider and discuss the Bulgarian urban system. It is also interesting to compare data on two groups of cities in different time intervals: (i) the whole Bulgaria city system which contains about 250 cities, - studied in the time interval between 2004 and 2011, and (ii) a system of 33 cities, - studied over the time interval 1887 till 2010. These latter cities are selected because the population was already over 10 000 inhabitants in 1946. It is shown that new additional indices are interestingly introduced in order to compensate defects in the Sheppard index. Numerical illustrations are illuminated through a "length ratio" measure, which allows to distinguish the (often) observed departures from the hyperbolic ranking seen by Jefferson.

  5. The City on Screen: A Methodological Approach on Cinematic City Studies

    2015-07-01

    Full Text Available The city has a strong memory and it never forgets its own experiences. The past, the present and the future of the city can be read in its streets, buildings, sounds, myths, rhythms and stories. More importantly, if the city is portrayed through a camera, it becomes as fictional and designable as films. At this stage, there is no difference between watching a film and seeing a city. Also, cinema itself turns into a paradigm that belongs to the city. This parallelism between the city and film is like an inevitable destiny so much so that they constitute and develop each other. Accordingly, those who attempt to understand the notion of the city should consult the films made about them and vice versa; hence, this paper deals with the question of how the city is cinematized, but this question involves another question: how does the cinematic imagination fictionalize itself in the city?

    Cities are often blamed for being the main emitters of greenhouse gases (up to 75% of CO_2 emissions are attributed to cities [IPCC, Climate Change Synthesis Report 2014]) due to the energy consumption tied to the activities they host: transport, industry, etc. But they are also the first to suffer from climate change: extreme climate events have more drastic outcomes in highly populated areas and the harmful effects of polluting activities are felt more strongly. Aware of the role that they can play, cities have been organising themselves into networks since the 1990's (C40, Cities Climate Leadership Group, ICLEI Local Governments for Sustainability, etc.) to share their experiences and reinforce their actions. Their commitment now singles them out as leading players: for example, London has announced an 80% reduction in its emissions by 2050, which is one of the most ambitious objectives targeted at local authority level or even national level. A comparative study conducted in five cities of the Global North and South (Agadir, Da Nang, Lima, London, Nantes) aimed at understanding their commitment to action on climate change. Why have they made this a priority? What concrete actions have been launched? What challenges are they facing?

    Full Text Available The article analyses the current problems of Vilnius city public transportation. The possible solutions (options and the technical means to improve the attractiveness of public transportation and accessibility are considered. Two main alternatives of means of electric transport (underground and tram have been singled out for Vilnius city. The suitability of these rail transport means have been substantiated. The nature and density of the work and residence places (areas of Vilnius city residents have been analysed. The scheme of tram and underground lines projected in Vilnius city are evaluated, which have been composed according to the current and forecasted flows of passengers, the nature of their changes and critical points. The technical economic indicators of the tram routes and underground lines in Vilnius city are analysed: average driving speed, average distance between the stations, the duration of the trip, the capacity of a single means of transport, the costs of line support and the size of investment. The accident rate of urban rail transportation is estimated. Comparative criteria of tram and underground lines are selected. The effectiveness of both rail means of transport in Vilnius city are compared according to three multi-criteria evaluation methods: the sum of ratings, simple additive weighting and geometrical means. The final conclusions and recommendations are provided.

    Material management faces a dual challenge: on the one hand satisfying large and increasing demands for goods and on the other hand accommodating wastes and emissions in sinks. Hence, the characterization of material flows and stocks is relevant for both improving resource efficiency and environmental protection. This article focuses on the urban scale, a dimension rarely investigated in past metal flow studies. We compare the copper (Cu) metabolism of two cities in different economic states, namely, Vienna (Europe) and Taipei (Asia). Substance flow analysis is used to calculate urban Cu balances in a comprehensive and transparent form. The main difference between Cu in the two cities appears to be the stock: Vienna seems close to saturation with 180 kilograms per capita (kg/cap) and a growth rate of 2% per year. In contrast, the Taipei stock of 30 kg/cap grows rapidly by 26% per year. Even though most Cu is recycled in both cities, bottom ash from municipal solid waste incineration represents an unused Cu potential accounting for 1% to 5% of annual demand. Nonpoint emissions are predominant; up to 50% of the loadings into the sewer system are from nonpoint sources. The results of this research are instrumental for the design of the Cu metabolism in each city. The outcomes serve as a base for identification and recovery of recyclables as well as for directing nonrecyclables to appropriate sinks, avoiding sensitive environmental pathways. The methodology applied is well suited for city benchmarking if sufficient data are available.

  13. Breach of Contact: An Intercultural Reading of China Miéville's 'The City and The City'

    Directory of Open Access Journals (Sweden)

    Barbara Elizabeth Hanna

    2014-08-01

    Full Text Available China Miéville’s 2009 'Weird' detective novel The City and The City is a tale of two city states, culturally distinct, between which unpoliced contact is forbidden. While residents of each city can learn about the other’s history, geography, politics, see photographs and watch news footage of the other city, relations between the two are tightly monitored and any direct contact requires a series of protocols, some of which might seem reasonable, or at least familiar: entry permits, international mail, international dialing codes, intercultural training courses. What complicates these apparently banal measures is the relative positioning of the two cities, each one around, within, amongst the other. The two populations live side by side, under a regime which requires ostentatious and systematic disregard or 'unnoticing' of the other in any context but a tightly regulated set of encounters. For all that interculturality is endemic to everyday life in the 21st century, what is striking is that critical and popular uptake of this novel so frequently decries the undesirability, the immorality even, of the cultural separation between the two populations, framing it as an allegory of unjust division within a single culture, and thus by implication endorsing the erasure of intercultural difference. We propose an alternative reading which sees this novel as exploring the management of intercultural encounters, and staging the irreducibility of intercultural difference. We examine how the intercultural is established in the novel, and ask how it compares to its representations in prevalent theoretical models, specifically that of the Third Place.

    Climate targets for cities abound. However, what these targets really imply is dependent on a number of decisions regarding system boundaries and methods of calculation. In order to understand and compare cities' climate targets, there is a need for a generic and comprehensive framework of key methodological considerations. This paper identifies eight key methodological considerations for the different choices that can be made when setting targets for GHG emissions in a city and arranges them in four categories: temporal scope of target, object for target setting, unit of target, and range of target. To explore how target setting is carried out in practice, the climate targets of eight European cities were analysed. The results showed that these targets cover only a limited part of what could be included. Moreover, the cities showed quite limited awareness of what is, or could be, include in the targets. This makes comparison and benchmarking between cities difficult. - Highlights: • Cities' climate targets are almost impossible to compare and benchmark. • There is a need for consistent protocols and frameworks supporting target setting. • A framework with key methodological considerations for cities' climate targets is identified. • The framework is used to explore the climate targets for eight European cities. • The difference between production- and consumption based accounting is illustrated in a new way

    A survey of female commercial sex workers (CSW) in Iloilo City, Philipines, was conducted in October and November 1995 to determine the level of knowledge, attitudes, and preventive practices regarding HIV/AIDS to guide future education programs. CSWs in the Philippines were categorized as registered or freelance. Registered CSWs included "hospitality girls" from licensed bars, night clubs, and massage parlors who have registered with the local social hygiene clinic (SHC). Freelance CSWs are not registered. 110 registered and 46 freelance CSWs were surveyed. We compared demographic data, scores from a basic knowledge test, and preventive practices between registered and freelance CSWs. Demographic data indicate that registered CSWs often originate from provinces outside of the Visayan Islands (25%) and most have never been married (93%). Freelance CSWs included more married (11%) and separated (11%) women from nearby cities. Knowledge test scores of registered and freelance CSWs were not significantly different. 90-96% of CSWs correctly answered questions regarding modes of transmission. However, 25% still believed it is possible to contract AIDS from using a public restroom. Registered and freelance CSWs believed their risks for AIDS to be equally great. However, 38% of freelance CSWs admit to never or almost never using condoms compared to 15% of registered CSWs. Licensed establishments and a support staff at the social hygiene clinic may provide a relatively structured working environment, giving registered CSWs security and confidence to insist on condom use. In most cases, condom use seems to depend on male customer compliance, and CSWs, especially freelancers, cannot afford to insist on condom use. The CSWs indicated that they learned most about AIDS through health personnel and television.

Today that the idea of smart city draws the attention of urban planners and policy makers and, at the same time, global competitiveness is considered essential for the success of a city, the paper aims to investigate the relationship between the concept of smart city and that of competitive city, identifying common characteristics and differences and answer the question: is “smartness” a new concept for urban studies? The analysis has been conducted in the Italian context, comparing the competitive structure of Italian provinces with their performance as smart cities. To rank Italian provinces because of their level of competitiveness, a previous ranking, carried out in 1995, has been updated with the most recent data available and the new hierarchy, thus obtained, has been compared with that of Italian smartest cities proposed by Forum PA.  The benchmarking shows that smartness and competitiveness are strictly connected: today, a city needs to improve its smart quotient in order to be more attractive and so more competitive, in fact, the efficiency and livability of cities, sought by potential citizens, can be improved by using ICTs, as supported by the advocates of smart cities, and represent a strategic factor for gaining a competitive advantage.

    As a new urban development pattern, the construction of sponge cities has been deeply integrated into the new urbanization and water safety strategy. Nanning City, as one of the first batch of experimental sponge cities in China, has undertaken exploration and practice on sponge city planning, construction, and management. The sponge city master plan of Nanning City establishes an urban ecological spatial pattern in order to protect the security of the sponge base. The sponge city construction strategy has also proposed an overall construction strategy of a sponge city in line with urban development features. Through the systematic analysis and planning, a “23+10+202” pattern of sponge city construction has been formed. “23” represents 23 drainage basins, in which major sponge facilities such as storage facilities, waterfront buffer zones, wetland parks, ecological rainwater corridor and sponge parks are allocated. “10” represents 10 sponge functional zones, which provide important reference for the establishment of sponge city construction index system. “202” represents 202 management units, which decomposes the general objective and provides technical support not only for sponge city construction and management, but also for the implementation of general objectives in the regulatory plan as well.

    Rosa Anna La Rocca

    2013-06-01

    Full Text Available The city of the future seems to be necessarily “intelligent” both in its physical and in functional features.This paper starts from the consideration that the diffusion of new communication technologies (ICTs is significantly changing the urban supply system of tourist services giving rise to new ways of enjoying the city.As tourism can be assumed as an urban activity, by a town planning point of view, the study of tourism is meaningful to identify development trajectories of the present cities targeted to sustainable and smarter models.As a matter of fact, almost all the projects to get a “smart city” are based on the idea of joining the potentialities of ICTs and the needs of urban management through people living or using the city.In such a vision, “tourist dimension” of the city becomes fundamental in promoting urban image as well as in improving efficiency of the city. This efficiency also depends on the capability of each city to share historical and cultural heritage as “common good”.As tourist demand has deeply changed also driven by technological development, this paper tries to investigate how the urban supply will change in order to meet the rising demand of quality and efficiency. The transition to smart tourist destination currently seems to be strongly connected with the number and the variety of apps to improve the “experiential component”. A lack of interest there seems to be in finding strategies and policies oriented to plan the urban supply of services tourist or not.This consideration, if shared, opens up new perspectives for research and experimentation in which city planning could have a key-role also in proposing an holistic approach to city development towards smart city.

    Full Text Available Abstract Background In 2005, Pakistan was first labeled as a country with concentrated epidemic of Human Immunodeficiency Virus (HIV. This was revealed through second generation surveillance conducted by HIV/AIDS Surveillance Project (HASP. While injection drug users (IDUs were driving the epidemic, subsequent surveys showed that Hijra (transgender sex workers (HSWs were emerging as the second most vulnerable group with an average national prevalence of 6.4%. An exceptionally high prevalence (27.6% was found in Larkana, which is a small town on the right bank of river Indus near the ruins of Mohenjo-Daro in the province of Sindh. This paper presents the risk factors associated with high prevalence of HIV among HSWs in Larkana as compared to other cities of the country. Methods Data were extracted for secondary analysis from 2008 Integrated behavioral and biological survey (IBBS to compare HSWs living in Larkana with those living in other cities including Karachi and Hyderabad in Sindh; Lahore and Faisalabad in Punjab; and Peshawar in Khyber Pakhtunkhwa provinces. After descriptive analysis, univariate and multivariate analyses were performed to identify risk factors. P value of 0.25 or less was used to include factors in multivariate analysis. Results We compared 199 HSWs from Larkana with 420 HSWs from other cities. The average age of HSWs in Larkana was 26.42 (±5.4 years. Majority were Sindhi speaking (80%, uneducated (68% and unmarried (97%. In univariate analysis, factors associated with higher prevalence of HIV in Larkana included younger age i.e. 20–24 years (OR: 5.8, CI: 2.809–12.15, being unmarried (OR: 2.4, CI: 1.0–5.7, sex work as the only mode of income (OR: 5.5, CI: 3.70–8.2 and longer duration of being involved in sex work 5–10 years (OR: 3.3, CI: 1.7–6.12. In multivariate logistic regression the HSWs from Larkana were more likely to lack knowledge regarding preventive measures against HIV (OR 11.9, CI: 3.4–41.08 and

    Cities are particularly vulnerable to climate risks due to their agglomeration of people, buildings and infrastructure. Differences in methodology, hazards considered, and climate models used limit the utility and comparability of climate studies on individual cities. Here we assess, for the first time, future changes in flood, heat-waves (HW), and drought impacts for all 571 European cities in the Urban Audit database using a consistent approach. To capture the full range of uncertainties in natural variability and climate models, we use all climate model runs from the Coupled Model Inter-comparison Project Phase 5 (CMIP5) for the RCP8.5 emissions scenario to calculate Low, Medium and High Impact scenarios, which correspond to the 10th, 50th and 90th percentiles of each hazard for each city. We find that HW days increase across all cities, but especially in southern Europe, whilst the greatest HW temperature increases are expected in central European cities. For the low impact scenario, drought conditions intensify in southern European cities while river flooding worsens in northern European cities. However, the high impact scenario projects that most European cities will see increases in both drought and river flood risks. Over 100 cities are particularly vulnerable to two or more climate impacts. Moreover, the magnitude of impacts exceeds those previously reported highlighting the substantial challenge cities face to manage future climate risks.

    Full Text Available Organizational culture is ultimately defined and practiced according to assumptions, attitudes, beliefs and values of the larger society it is imbedded. Organizational culture varies from one organization to the other. Thus, a closer look at the Philippine public administration shows that the Filipino culture is a special kind of environment. The reason being that there are three major traits that showcase the Filipino behavior and decision-making: personalism, familism, and particularism or popularism. The city governments of Batangas, Lipa and Tanauan like any other City Government have their own unique culture. This distinctness is based on many factors such as: events, history, past leadership as well as current leadership that results in routines or the way things are done in their respective institution. This paper presents a comparative analysis of organizational culture and employee’s motivation of selected cities in CALABARZON: Basis for Employee’s Motivation, Leadership and Innovative Management. The descriptive correlation method of research was used to gather the needed information. The result revealed that the three cities all agreed as to the organizational culture and levels of motivation. Overall, working relationship was found to be the best predictor among the organizational culture. While the best motivator among employees, was their need for achievement. Lastly, a proposed program to further boost employee’s motivation/morale, leadership, and innovative management was tabled based on the significance of the findings of the research.

    2010-04-01

    Full Text Available The issue of the safety of mobility in the urban environment has been emerging as a primary social topic for some time now due to the number of casualties and, more generally, due to the impact on living conditions in the city. If correctly formulated, in fact, this subject has implications primarily and fundamentally with regard to the quality of urban life, as the citizen, and the vulnerable road user in particular, is severely restricted in their use of urban public paces. Consequently, an increasingly greater focus is being placed on acquiring methods, techniques and strategies for addressing the issue of planning, constructing and managing roads, squares and urban green spaces (and above all, applying the logic of reclaiming the historic and consolidated city in order that the city can be used to its full potential by the citizen. The subject itself therefore presents an opportunity to re-establish urban planning regulations (and, more generally, city regulations in accordance with the renewed interest in public spaces. The article discusses this matter and includes supporting elements and examples, also referring to the implications on the urban landscape.

    2014-12-01

    Full Text Available Aim: In the present study, a therapeutic trial was conducted to assess comparative efficacy of crystalloid plus colloid and crystalloid intravenous infusions alone as fluid therapy in dogs suffering from hemorrhagic gastroenteritis (HGE. Materials and Methods: 20 dogs manifesting HGE, presented at Teaching Veterinary Clinical Services Complex, Ludhiana, Punjab, were selected randomly for the trial. All of them were observed to suffer from moderate dehydration on clinical examination. Crystalloids 5% DNS and RL were used in combination with polygelin 3.5% colloidal solution in the first group (Combination I and in the second group, the afore-said crystalloids (Combination II were used, both groups consisting of 10 cases each. Antibiotics and symptomatic treatment were same for all the 20 cases. The outcome of both treatment groups was evaluated on hemato-biochemical parameters, before and after administration of the therapies and compared statistically within and between the two groups. Hemato-biochemical parameters of eight clinically healthy animals were considered as control for comparison. Result: On hemato-biochemical examination, significant alterations were observed in leucogram, platelet and serum globulin concentration after the treatment in the first group as compared to before treatment values. In the second group, mean hemoglobin varied significantly after the treatment. After therapies were administered, significant difference in serum globulin level and albumin: Globulin was found in between the treatment groups (Combination I and Combination II. Clinical recovery was faster in the first group than the second group of animals. Conclusion: On hemodynamic and laboratory data, efficacies of both the fluid therapies were equivocal. Colloidal solutions may hasten recovery in small animals suffering from gastrointestinal crisis.

    Full Text Available After a systematic review of 38 current intelligent city evaluation systems (ICESs from around the world, this research analyzes the secondary and tertiary indicators of these 38 ICESs from the perspectives of scale structuring, approaches and indicator selection, and determines their common base. From this base, the fundamentals of the City Intelligence Quotient (City IQ Evaluation System are developed and five dimensions are selected after a clustering analysis. The basic version, City IQ Evaluation System 1.0, involves 275 experts from 14 high-end research institutions, which include the Chinese Academy of Engineering, the National Academy of Science and Engineering (Germany, the Royal Swedish Academy of Engineering Sciences, the Planning Management Center of the Ministry of Housing and Urban-Rural Development of China, and the Development Research Center of the State Council of China. City IQ Evaluation System 2.0 is further developed, with improvements in its universality, openness, and dynamic adjustment capability. After employing deviation evaluation methods in the IQ assessment, City IQ Evaluation System 3.0 was conceived. The research team has conducted a repeated assessment of 41 intelligent cities around the world using City IQ Evaluation System 3.0. The results have proved that the City IQ Evaluation System, developed on the basis of intelligent life, features more rational indicators selected from data sources that can offer better universality, openness, and dynamics, and is more sensitive and precise.

  5. Urban Big Data and the Development of City Intelligence

    Yunhe Pan

    2016-06-01

    Full Text Available This study provides a definition for urban big data while exploring its features and applications of China's city intelligence. The differences between city intelligence in China and the “smart city” concept in other countries are compared to highlight and contrast the unique definition and model for China's city intelligence in this paper. Furthermore, this paper examines the role of urban big data in city intelligence by showing that it not only serves as the cornerstone of this trend as it also plays a core role in the diffusion of city intelligence technology and serves as an inexhaustible resource for the sustained development of city intelligence. This study also points out the challenges of shaping and developing of China's urban big data. Considering the supporting and core role that urban big data plays in city intelligence, the study then expounds on the key points of urban big data, including infrastructure support, urban governance, public services, and economic and industrial development. Finally, this study points out that the utility of city intelligence as an ideal policy tool for advancing the goals of China's urban development. In conclusion, it is imperative that China make full use of its unique advantages—including using the nation's current state of development and resources, geographical advantages, and good human relations—in subjective and objective conditions to promote the development of city intelligence through the proper application of urban big data.

  8. @City: technologising Barcelona

    Directory of Open Access Journals (Sweden)

    Rojas, Jesús

    2007-05-01

    Full Text Available This article is about the concept of the contemporary city - the influence that technology has when one thinks about, plans and lives in a city. The conjunction of technology and city reformulates customs and social practices; it can even determine the way one constitutes one's own identity. One can see how close the relation is between technology (specifically, TICS and the structures of the city in a wide variety of situations: in social interactions on the street, in transport, and in ways of buying, of working and entertainment. "@City" is a concept that very well reflects the emergent properties of a current city, that is, the coexistence of a physical and a virtual urban space. The "22@Barcelona" project attempts to bring together different types of spaces. By combining the physical with the virtual, 22@Barcelona, as a neighborhood of @City, creates an uncertain and blurred border between both spaces.The article also examines the impact that these spaces have on the psycho-social processes involved in the daily life of a traditionally working-class neighborhood, now strongly limited by technological boundaries.

    Bi Jun; Zhang Rongrong; Wang Haikun; Liu Miaomiao; Wu Yi

    2011-01-01

    The development of urbanization is accelerating in China, and there are great pressures and opportunities in cities to reduce carbon emissions. An emissions inventory is a basic requirement for analyzing emissions of greenhouse gases (GHGs), their potential reduction and to realize low-carbon development of cities. This study describes a method to establish a GHGs emissions inventory in Chinese cities for 6 emission sources including industrial energy consumption, transportation, household energy consumption, commercial energy consumption, industrial processes and waste. Nanjing city was selected as a representative case to analyze the characteristics of carbon emissions in Chinese cities. The results show that carbon emissions in Nanjing have increased nearly 50% during the last decade. The three largest GHGs contributors were industrial energy consumption, industrial processes and transportation, which contributed 37-44%, 35-40% and 6-10%, respectively, to the total GHGs emissions. Per GDP carbon emissions decreased by 55% from 2002 to 2009, and the per capita and per GDP carbon emissions were comparable or even lower than the world average levels. These results have important policy implications for Chinese cities to control their carbon emissions. - Highlights: → Carbon emissions inventory using bottom-up methodology was firstly reported for a Chinese city. → Emission characteristics of Nanjing city were compared with other international cities. → Low carbon policies for Chinese cities were recommended based on the results of this research.

  13. City Carbon Footprint Networks

    Guangwu Chen

    2016-07-01

    Full Text Available Progressive cities worldwide have demonstrated political leadership by initiating meaningful strategies and actions to tackle climate change. However, the lack of knowledge concerning embodied greenhouse gas (GHG emissions of cities has hampered effective mitigation. We analyse trans-boundary GHG emission transfers between five Australian cities and their trading partners, with embodied emission flows broken down into major economic sectors. We examine intercity carbon footprint (CF networks and disclose a hierarchy of responsibility for emissions between cities and regions. Allocations of emissions to households, businesses and government and the carbon efficiency of expenditure have been analysed to inform mitigation policies. Our findings indicate that final demand in the five largest cities in Australia accounts for more than half of the nation’s CF. City households are responsible for about two thirds of the cities’ CFs; the rest can be attributed to government and business consumption and investment. The city network flows highlight that over half of emissions embodied in imports (EEI to the five cities occur overseas. However, a hierarchy of GHG emissions reveals that overseas regions also outsource emissions to Australian cities such as Perth. We finally discuss the implications of our findings on carbon neutrality, low-carbon city concepts and strategies and allocation of subnational GHG responsibility.

  14. Tales of two cities: political capitals and economic centres in the world city network.

    Directory of Open Access Journals (Sweden)

    Peter J. Taylor

    2014-12-01

    Full Text Available The majority of major cities in the world city network are capital cities. Between primacy and political specialization there are examples of countries where the capital city and a second city remain as major rival cities in contemporary globalization. In this paper we focus upon situations where the capital city is less important in global economic capacity: Rome and Milan, Berlin and Frankfurt, Abu Dhabi and Dubai, Delhi and Mumbai, Islamabad and Karachi. This is an exercise in double comparisons: between cities in each pairing and between the pairings. Despite the massive differences – economic, cultural and political – amongst our chosen pairs of cities we have found communalities relating to the specific circumstance we are investigating. First, there is some evidence that economic centres are more global and less local than their capital cities. Second, more particularly, we have shown that in terms of global economic connections there is a very consistent pattern: economic centres have a much more coherent and telling integration into the world city network.

Objectives: The objective of this study was to assess the satisfaction among the stakeholders participating in the MDS program of a premier Dental College in Ludhiana. Methodology: A cross-sectional survey was conducted in 12 villages of Ludhiana district in Punjab where the MDSs were being provided. Four hundred and fifty patients, 50 organizers and 40 service providers were interviewed separately with pretested questionnaires. Results: About 98.4% of the patients were completely satisfied with the overall care provided. 71.1% of the patients felt there was increased times in services and 76.7% felt that there was inadequate referral network. Most patients were satisfied with the communication skills of the doctors. 57.5% of the organizers felt that the overall care provided in the MDSs was consistently good and high quality in spite of challenging infrastructure. 100% of the health care providers felt that working in the MDS was a good learning experience in spite of the heavy workload and infrastructure challenges. Conclusion: The study reveals that the MDS is a satisfactory mode of dental care delivery for all the stakeholders involved. Despite the challenges, this partnership program can be nurtured as a successful model of oral health care delivery in underserved areas.

    There is a strong connection between economic growth and development of cities. Economic growth tends to stimulate city growth, and city economies have often shaped innovative environments that in turn support economic growth. Simultaneously, social and environmental problems related to city growth...... can be serious threats to the realization of the socio-economic contributions that cities can make. However, as a result of considerable diversity of competences combined with interactive learning and innovation, cities may also solve these problems. The ‘urban order’ may form a platform...... for innovative problem solving and potential spill-over effects, which may stimulate further economic growth and development.

We investigate how urban environment, political structure and residential behavior can best be adapted, with attention to the interactions among structural, political, and sociological configurations and with their consequences on human health. Demographers project that in the EU-25-States by 2050, approximately 30% of the population will be over age 65. Also by 2050, average tem¬peratures are projected to rise by 1 to 2 K. Combined, Europe can expect enhanced thermal stress and higher levels of particulate matter. CITY 2020+ amongst other sub-projects includes research project dealing with (1) a micro-scale assessment of blockages to low-level cold-air drainage flow into the city centre by vegetation and building structures, (2) a detailed analysis of the change of probability density functions related to the occurrence of heat waves during summer and the spatial and temporal structure of the urban heat island (UHI) (3) a meso-scale analysis of particulate matter (PM) concentrations depending on topography, local meteorological conditions and synoptic-scale weather patterns. First results will be presented specifically from sub-projects related to vegetation barriers within cold air drainage, the assessment of the UHI and the temporal and spatial pattern of PM loadings in the city centre. The analysis of the cold air drainage flow is investigated in two consecutive years with a clearing of vegetation stands in the beginning of the second year early in 2010. The spatial pattern of the UHI and its possible enhancement by climate change is addressed employing a unique setup using GPS devices and temperature probes fixed to

    This article gives a brief overview of the Internet of Things (IoT) for cities, offering examples of IoT-powered 21st century smart cities, including the experience of the Spanish city of Barcelona in implementing its own IoT-driven services to improve the quality of life of its people through measures that promote an eco-friendly, sustainable environment. The potential benefits as well as the challenges associated with IoT for cities are discussed. Much of the 'big data' that are continuously generated by IoT sensors, devices, systems and services are geo-tagged or geo-located. The importance of having robust, intelligent geospatial analytics systems in place to process and make sense of such data in real time cannot therefore be overestimated. The authors argue that IoT-powered smart cities stand better chances of becoming healthier cities. The World Health Organization (WHO) Healthy Cities Network and associated national networks have hundreds of member cities around the world that could benefit from, and harness the power of, IoT to improve the health and well-being of their local populations.

  6. From City-States to Global Cities: the role of Cities in Global Governance

    Directory of Open Access Journals (Sweden)

    2017-11-01

    Full Text Available Global governance has altered institutional architecture and the systemic and institutional conditions under which power is exercised, as well as the characteristics of the political system, the form of government, and the system of intermediation of interests. However, although it has surpassed the State’s dimension of power, it created new interstate dimensions and new relations between powers, particularly at the level of cities. Cities have helped to solve common problems in a more efficient and effective way by facilitating the exchange of knowledge, sharing of solutions and resources, and building capacity to implement and monitor progress in order to achieve collectively agreed goals, in a bottom-up approach. Cities have the virtue of securing the most direct social and political contract between societies and the notion of authority. This study, therefore, aims to reflect on this emerging, less hierarchical and rigid governance and address complex global challenges such as climate and demographic change; increasing crime rates; disruptive technology; and pressures on resources, infrastructure and energy. As a global/local interface, cities can ensure effective solutions to current challenges and act together in areas where the global agenda has stalled.

  9. Spatio-Semantic Comparison of Large 3d City Models in Citygml Using a Graph Database

    A city may have multiple CityGML documents recorded at different times or surveyed by different users. To analyse the city's evolution over a given period of time, as well as to update or edit the city model without negating modifications made by other users, it is of utmost importance to first compare, detect and locate spatio-semantic changes between CityGML datasets. This is however difficult due to the fact that CityGML elements belong to a complex hierarchical structure containing multi-level deep associations, which can basically be considered as a graph. Moreover, CityGML allows multiple syntactic ways to define an object leading to syntactic ambiguities in the exchange format. Furthermore, CityGML is capable of including not only 3D urban objects' graphical appearances but also their semantic properties. Since to date, no known algorithm is capable of detecting spatio-semantic changes in CityGML documents, a frequent approach is to replace the older models completely with the newer ones, which not only costs computational resources, but also loses track of collaborative and chronological changes. Thus, this research proposes an approach capable of comparing two arbitrarily large-sized CityGML documents on both semantic and geometric level. Detected deviations are then attached to their respective sources and can easily be retrieved on demand. As a result, updating a 3D city model using this approach is much more efficient as only real changes are committed. To achieve this, the research employs a graph database as the main data structure for storing and processing CityGML datasets in three major steps: mapping, matching and updating. The mapping process transforms input CityGML documents into respective graph representations. The matching process compares these graphs and attaches edit operations on the fly. Found changes can then be executed using the Web Feature Service (WFS), the standard interface for updating geographical features across the web.

    To compare the acute-poisoning characteristics between city and rural areas of Guangxi Province in order to provide clinical data for the formation of treatment strategies of acute poisoning in Guangxi. Data of acute poisoning patients as treated in 36 municipal and 12 county hospitals, and also 15 rural clinics in 11 cities of Guangxi during 2005 to 2009 were collected and analyzed according to poisoning population, poisoning site, poisoning process, and poisoning degree. By analysing 3678 and 2153 cases of acute poisoning patients in rural and urban areas, the gender [χ (2) = 5.53, P old (11.17% vs. 8.69%), farmers by occupation (74.84% vs. 2.79%), home (80.64% vs. 78.07%), sites of labor (11.83% vs. 3.07%) and other sites (4.08% vs. 2.97%), and the chief causes were professional (3.10% vs. 1.30%), taken by mistake (21.85% vs. 20.91%), homicide (0.30% vs. 0.28%), and suicide (39.07% vs. 18.77%), and by pesticide (60.94% vs. 12.13%), plant (7.08% vs. 2.88%) and animal poisons (7.73% vs. 6.56%), belonging to severe poisoning (25.86% vs. 19.04%) were higher than those in town. In the town, poisoning occurred predominantly in female (55.09% vs. 51.90%), age below 19 years old (23.78% vs. 19.44%), unemployed (33.35% vs. 13.76%), student (17.53% vs. 8.43%), industrial workers (31.95% vs. 2.69%), executives (10.84% vs. 0.22%) and other professional (3.53% vs. 0.05%); occurred in schools (8.78% vs. 0.82%), restaurants (5.48% vs. 1.55%), place of entertainment (1.63% vs. 1.09%), by accidental (52.23% vs. 31.27%), therapeutic (4.46% vs. 2.56%), and other reasons (2.04% vs. 1.85%); by chemicals (33.19% vs. 8.55%), medicines (24.31% vs. 9.12%), and other types of poison (20.92% vs. 6.59%); light and medium degree of poisoning (44.87% vs. 41.22%, 36.09% vs. 32.93%) were higher than those in rural areas. Regarding the acute poisoning in Guangxi, the composition of population, the poisoning sites and causes, the types of poisons, the poisoning degree are distinctly different

    Full Text Available Introduction: Oral diseases associated with psychological disorders have long been known in medicine. Emotional as well as psychological factors may act as significant risk factors in the initiation and progression of oromucosal diseases. Aims and Objectives: The aim of this study was to determine a correlation between stress and development of certain oral conditions such as lichen planus, myofacial pain dysfunction syndrome, xerostomia, bruxism, aphthous ulcers, and burning mouth syndrome. Materials and Methods: An observational comparative study was conducted among patients reporting to the Department of Oral Medicine and Radiology. A total of 130 patients gave a positive history of oral lesions, out of which 62 were stress related and the other 68 patients served as the control group (oral lesions with no history of stress. All these patients were subjected to routine systemic and oral examination. The results obtained were statistically compared using P value, t-test, and Chi-square test. Results: It was found that lichen planus and burning mouth syndrome were more common in females and myofacial pain dysfunction syndrome was prevalent in males. Xerostomia was found to increase with age. Conclusion: It was concluded that, though the etiology of most oral lesions is not known, the role of stress and other psychogenic factors cannot be ruled out in their occurrence.

    2015-11-01

    Heat waves are the most significant cause of mortality in the US compared to other natural hazards. Prior studies have found increased heat exposure for individuals of lower socioeconomic status in several US cities, but few comparative analyses of the social distribution of urban heat have been conducted. To address this gap, our paper examines and compares the environmental justice consequences of urban heat risk in the three largest US cities: New York City, Los Angeles, and Chicago. Risk to urban heat is estimated on the basis of three characteristics of the urban thermal landscape: land surface temperature, vegetation abundance, and structural density of the built urban environment. These variables are combined to develop an urban heat risk index, which is then statistically compared with social vulnerability indicators representing socioeconomic status, age, disability, race/ethnicity, and linguistic isolation. The results indicate a consistent and significant statistical association between lower socioeconomic and minority status and greater urban heat risk, in all three cities. Our findings support a growing body of environmental justice literature that indicates the presence of a landscape of thermal inequity in US cities and underscores the need to conduct comparative analyses of social inequities in exposure to urban heat.

  16. Expansion and growth in Chinese cities, 1978–2010

    Schneider, A; Mertes, C M

    2014-01-01

    It has long been recognized that compact versus more sprawling urban forms can have very different environmental impacts. As the Chinese population continues to rapidly urbanize, the size, shape, and configuration of cities in China will undoubtedly change to accommodate expansion of housing, industry, and commerce, causing direct and indirect environmental impacts at multiple scales. It is therefore imperative to understand how urban areas are evolving as socio-economic reforms in China are implemented across different regions. This paper compares trends in 142 Chinese cities (including 17 agglomerations) to understand urban expansion and population growth following reforms, 1978–2010. The results show that cities tripled in size, while doubling in population over the same period. In coastal areas targeted by early policies, urban land increased 4–5 times since 1978, for all city sizes. Large agglomerations are the primary consumers of land in coastal and western regions, each adding an average of 450 km 2 during the study period, while small-medium cities consumed an average 20 km 2 . Although populations in these agglomerations increased an average 1.3 million, 2000–2010, cities within 100 km of each agglomeration grew >1.8 million collectively. Proximity to large agglomerations contributed to the growth of small-medium cities, especially in western regions. (paper)

  17. Transnational city carbon footprint networks – Exploring carbon links between Australian and Chinese cities

    Highlights: • A trans-national, multi-region input-output analysis for cities is presented. • We examine the carbon footprint network of ten cities. • The balance of emissions embodied in trade discloses a hierarchy of responsibility. • We model how emissions reductions spread through the city carbon networks. • Implications on the Chinese and Australian carbon trading schemes are discussed. - Abstract: Cities are leading actions against climate change through global networks. More than 360 global cities announced during the 2015 Paris Climate Conference that the collective impact of their commitments will deliver over half of the world’s urban greenhouse gas emissions reductions by 2020. Previous studies on multi-city carbon footprint networks using sub-national, multi-region input-output (MRIO) modelling have identified additional opportunities for addressing the negative impacts of climate change through joint actions between cities within a country. However, similar links between city carbon footprints have not yet been studied across countries. In this study we focus on inter-city and inter-country carbon flows between two trading partners in a first attempt to address this gap. We construct a multi-scale, global MRIO model to describe a transnational city carbon footprint network among five Chinese megacities and the five largest Australian capital cities. First, we quantify city carbon footprints by sectors and regions. Based on the carbon map concept we show how local emissions reductions influence other regions’ carbon footprints. We then present a city emissions ’outsourcing hierarchy’ based on the balance of emissions embodied in intercity and international trade. The differences between cities and their position in the hierarchy emphasize the need for a bespoke treatment of their responsibilities towards climate change mitigation. Finally, we evaluate and discuss the potentially significant benefits of harmonising and aligning China

    Health Organization (WHO) guideline concentration limits for O3 and of the regulatory limits for NO2. Model tests were performed with CityChem to study the ozone formation rate with simultaneous variation of emissions of nitrogen oxides (NOx) and volatile organic compounds (VOC). Emissions of VOC in urban areas are not well quantified as they may originate from various sources, including solvent usage, industry, combustion plants and vehicular traffic. The employed chemical mechanism contains large uncertainties with respect to ozone formation. Observed high-O3 episodes were analyzed by comparing modelled pollutant concentrations with concentration data from the Hamburg air quality surveillance network (http://luft.hamburg.de/). The analysis inspected possible reasons for too low modelled O3 in summer such as missing emissions of VOC from natural sources like green parks and the vertical exchange of O3 towards the surface.

  20. Older adults abuse in three Brazilian cities

    Rosalina Aparecida Partezani Rodrigues

    Full Text Available ABSTRACT Objective: To analyze the police reports filed by older adults who suffered abuse in order to identify the socio-demographic characteristics of victims and aggressors, type of violence, location, as well as to compare rates in three Brazilian cities in the period from 2009 to 2013. Method: Ecological study, in which 2,612 police reports registered in Police Stations were analyzed. An instrument was used to obtain data from the victim, the aggressor and the type of violence. Results: Psychological abuse predominated and most cases occurred in the older adults own home. In the cities of Ribeirão Preto and João Pessoa, the older adults presented similar rates for both gender. Regarding the standardized rates, in João Pessoa, there was a rise of this type of abuse in the two first years, and later there was a certain stability. In the city of Teresina, there was an increase, also observed in the city of Ribeirão Preto in the three first years, followed by a decrease. Conclusion: Older adults abuse is a cultural phenomenon difficult to be reported by them, since it occurs in the family context.

    Full Text Available As an archipelagic country, many cities in Indonesia exist and grow at the waterfronts. This research aims to explore comparatively the spatial structure of two waterfront cities: Kendari represents a bay-front with U-form coast line, and Manado as a sea-front with straight line coast line. The spatial structures are represented by spatial pattern, land use pattern, population density, road network, BCR and urban hierarchy. Data were collected through field survey, reading government documents and doing in-depth interview of some key informants. Descriptive and comparative analyses - both similarities and differences - on spatial structures were focused on the relationships between spatial structures with the existence of the waterfronts. The findings show that at the early period of growth, spatial structures of both cities were formed by the existence of the waterfront similarly. Influenced by physical development such as commercial facilities and housing settlements, the spatial structure recently spreads out to the mainland area created some new sub-centers. Understanding the character of spatial structures will be significant for directing and controlling the urban land use to create a sustainable waterfront city.

    66,000 children and adolescents are treated at emergency departments (EDs) in England and Wales each year for assault injury. The aim of this study was to compare adolescent assault injury rates in cities and towns and determine how assault injury varies with deprivation and gender. The study was set in three cities in Wales, UK, and their surrounding towns. Subjects were 11-17 year olds treated for assault injury at one of seven EDs from 1 October 2005 to 30 September 2006. Area of residence (electoral divisions, EDivs) was identified from patient postcode. EDivs were aggregated into deprivation fifths for males and females and cities and towns. Assault injury rates, rate ratios and 95% CIs were calculated. 1472 children and adolescents of 11-17 years old were treated for assault injury. Male city assault injury rates were 14.2/1000 11-17 year olds; and 13.1 in towns. Female city assault injury rates were 6.0; and 5.6 in towns. In the most deprived city areas males had assault injury rates 2.6 times (95% CI 1.85 to 3.59) that of the most affluent, compared with 2.0 times in towns (95% CI 1.39 to 2.86). For females, the most deprived city areas had assault injury rates 5.3 times that of the most affluent (95% CI 2.93 to 9.41), compared with 2.8 times in towns (95% CI 1.47 to 5.28). Injury in youth violence increased with increasing deprivation in cities and their feeder towns. This was true for boys and girls, though rates for boys were consistently higher. This link between assault injury and deprivation was stronger for girls in cities than in feeder towns. Strategies to prevent youth violence need to include improved safeguarding arrangements for girls living in the most deprived city areas.

    An indoor radon survey of a total of 269 dwellings, with one dosimeter per house, distributed in four Saudi Arabian cities was carried out. The objective of this survey was to carry out indoor radon measurements of two cities in the Eastern Province, Khafji and Hafr Al-Batin and to compare this with two cities in the Western Province, Al-Madina and Taif. The survey provides additional information about indoor radon concentrations in Saudi Arabia. The results of the survey in these cities showed that the overall minimum, maximum and average radon concentration were 7,137 and 30 Bq m{sup -3}, respectively. The lowest average radon concentration (20 Bq m{sup -3}) was found in Hafr Al-Batin, while the highest average concentration was found in Khafji (40 Bq m{sup -3})

  5. Quality of life declines in big and growing cities. Poverty in cities.

    1997-01-01

    The quality of life in developing countries during the first couple of decades after the Second World War was higher in cities than in small towns and villages. However, the relative advantage of city dwellers in developing countries has declined since the 1970s, with high-growth rate cities experiencing a more severe decline. Infant mortality levels in Latin America and sub-Saharan Africa in the 1990s are as high in large cities as in the smallest towns and villages. In most developing regions, big city residents are increasingly disadvantaged, such that researchers and policymakers can no longer assume that the quality of life in urban areas is better than in rural areas. The urban transformation of the developing world is similar to the 19th century urbanization of now-developed countries, but today many more people are crowding into far bigger cities. Using survey information from 43 countries representing 63% of the developing world's urban population outside of China and India, Martin Brockerhoff of the Population Council and Ellen Brennan of the UN Population Division found that rapid population growth and big size have overwhelmed the capacity of cities to provide essential goods and services.

    2008-12-01

    Full Text Available The process of imaging for city marketing purposes has the implication on culture, conservation and heritage. City marketing, especially in the European context, has been examined in interdisciplinary literature with special focus on imaging for tourism. Little is reported about the imaging of those cities' ex-colonies in the East. The Historic City of Georgetown in Penang, dubbed 'the City of Living Culture', has been gearing her development towards living up to the image. This paper examines the imaging of the Historic City of Georgetown for heritage tourism and city marketing tool by the public agencies involved. A short introduction to city marketing, imaging and heritage tourism is offered due to sparse literature in the built environment literature and to serve as a foundation to the main discourse of this paper. The bulk of this paper discusses the conservation of heritage as image dimensions in the marketing of Georgetown. We submitted that Georgetown has successfully utilised and capitalised on its cultural diversity and tangible heritage based on its colonial legacy to promote the city as evidenced by its recent inscription into UNESCO's World Heritage Site list. Nonetheless, building and maintaining the synergy between the government, the private sector and the people is essential for the city's heritage tourism industry.

  8. The cultural heritage tourism in the city of Heidelberg, Germany: Plans, motivations and realities

    Directory of Open Access Journals (Sweden)

    Ferreira Pires Daniel Vítor

    2014-01-01

    Full Text Available In recent years, heritage has been responsible for the visibility that a large number of cities around the world have been getting as regards affirmation and differentiation of places. This also increased the number of cultural tourists that visit those cities worldwide. In this struggle for affirmation and differentiation, Heidelberg has quite an advantage, since the city's cultural heritage, as well as its unique atmosphere, have been spread by the Romantic Movement in the 19th century and it still happens nowadays, after more than two hundred years. But is Heidelberg indeed a city that receives cultural tourists? In this article, through an exploratory study, we intend to characterize the tourists that visit the city, to understand if the defined politics, actions and events taken by the different institutional authorities (like the Heidelberger Marketing and City Town hall, among others are getting the expected results. Through literature review and question­naires completed by the city's tourists, based on a probabilistic random sample and semi-structured interviews, we expect to trace the evolution of the policies defined, and compare those to the type of tourists that actually visit the city. As a preliminary result, we concluded that there is a difference between the tourist profile defined by the institutional authorities with responsibilities in the promotion and communication of the city's cultural heritage assets, comparing with the tourists that actually visit the city. This is the result not only of the motivations and effective length of the visits, but also in the lack of alternative or multiple visit narratives and routes for the cultural heritage city's assets.

    Young injection drug users (IDUs), a highly mobile population, engage in high levels of injecting risk behavior, yet little is understood about how such risk behavior may vary by the characteristics of the cities to which they travel, including the existence of a syringe exchange program (SEP), as well as travel partner characteristics. In 2004-2005, we conducted a 6-month prospective study to investigate the risk behavior of 89 young IDUs as they traveled, with detailed information gathered about 350 city visits. In multivariable analyses, travel to larger urban cities with a population of 500,000-1,000,000 was significantly associated with injecting drugs (adjusted odds ratio (AOR) = 3.71; 95 % confidence interval (CI), 1.56-8.82), ancillary equipment sharing (AES; AOR = 7.05; 95 % CI, 2.25-22.06) and receptive needle sharing (RNS; AOR = 5.73; 95 % CI, 1.11-27.95), as compared with visits to smaller cities with populations below 50,000. Region of the country, and the existence of a SEP within the city visited, were not independently associated with injecting drugs, AES, or RNS during city visits. Traveling with more than one injecting partner was associated with injecting drugs during city visits (AOR = 2.77; 95 % CI, 1.46-5.27), when compared with traveling alone. Additionally, both non-daily and daily/almost daily alcohol use during city visits were associated with AES (AOR = 3.37; 95 % CI, 1.42-7.68; AOR = 3.03; 95 % CI, 1.32-6.97, respectively) as compared with no alcohol consumption. Traveling young IDUs are more likely to inject when traveling with other IDUs and to engage in higher risk injection behavior when they are in large cities. Risk behavior occurring in city visits, including equipment sharing and alcohol consumption, suggests further need for focused interventions to reduce risk for viral infection among this population.

  11. Urban physiology: city ants possess high heat tolerance.

    Directory of Open Access Journals (Sweden)

    Michael J Angilletta

    Full Text Available Urbanization has caused regional increases in temperature that exceed those measured on a global scale, leading to urban heat islands as much as 12 degrees C hotter than their surroundings. Optimality models predict ectotherms in urban areas should tolerate heat better and cold worse than ectotherms in rural areas. We tested these predications by measuring heat and cold tolerances of leaf-cutter ants from South America's largest city (São Paulo, Brazil. Specifically, we compared thermal tolerances of ants from inside and outside of the city. Knock-down resistance and chill-coma recovery were used as indicators of heat and cold tolerances, respectively. Ants from within the city took 20% longer to lose mobility at 42 degrees C than ants from outside the city. Interestingly, greater heat tolerance came at no obvious expense of cold tolerance; hence, our observations only partially support current theory. Our results indicate that thermal tolerances of some organisms can respond to rapid changes in climate. Predictive models should account for acclimatory and evolutionary responses during climate change.

    Full Text Available In recent years European Commission has developed a set of documents for Members States tracing, directly or indirectly, recommendations for the transformation of the European city. The paper wants to outline which future EU draws for the city, through an integrated and contextual reading of addresses and strategies contained in the last documents, a future often suggested as Smart City. Although the three main documents (Cohesion Policy 2014-2020 of European Community, Digital Agenda for Europe and European Urban Agenda face the issue of the future development of European cities from different points of view, which are respectively cohesion social, ICT and urban dimension, each of them pays particular attention to urban and territorial dimension, identified by the name of Smart City. In other words, the paper aims at drawing the scenario of evolution of Smart Cities that can be delineated through the contextual reading of the three documents. To this end, the paper is divided into three parts: the first part briefly describes the general contents of the three European economic plan tools; the second part illustrates the scenarios for the future of the European city contained in each document; the third part seeks to trace the evolution of the Smart Cities issue developed by the set of the three instruments, in order to provide the framework of European Community for the near future of our cities

    The purpose of this paper is to discuss conceptual requirements for a City Sustainability Index (CSI) and to review existing major sustainability indices/indicators in terms of the requirements. The following indices are reviewed: Ecological Footprint (EF), Environmental Sustainability Index (ESI), Dashboard of Sustainability (DS), Welfare Index, Genuine Progress Indicator (GPI), Index of Sustainable Economic Welfare, City Development Index, emergy/exergy, Human Development Index (HDI), Environmental Vulnerability Index (EVI), Environmental Policy Index (EPI), Living Planet Index (LPI), Environmentally-adjusted Domestic Product (EDP), Genuine Saving (GS), and some applications of composite indices or/and multivariate indicators to local or regional context as case studies. The key conceptual requirements for an adequate CSI are: (i) to consider environmental, economic and social aspects (the triple bottom line of sustainability) from the viewpoint of strong sustainability; (ii) to capture external impacts (leakage effects) of city on other areas beyond the city boundaries particularly in terms of environmental aspects; (iii) to create indices/indicators originally for the purpose of assessing city sustainability; and (iv) to be able to assess world cities in both developed and developing countries using common axes of evaluation. Based on the review, we conclude that it is necessary to create a new CSI that enables us to assess and compare cities' sustainability performance in order to understand the global impact of cities on the environment and human life as compared with their economic contribution. In the future, the CSI will be able to provide local authorities with guidance toward sustainable paths. - Highlights: Black-Right-Pointing-Pointer We derive the four key requirements for a new City Sustainability Index (CSI) system.

    According to the world traveller that have visited the old cities on the Java Island in the 15th century, the cities have a seaport. The sea port became a place for transit and stay until grown as a coastal city, Unfortunately, some of these cities have disappeared due to the process of secretions. Semarang in the 14th century also had a sea port as a landing area in Kampung Melayu. Recently the village no longer located in the coastal but in the middle of the city. How to prove that the area was a coastal area? By tracing some architectural remains, toponimy and comparing with the Javanese urban design pattern revealed the old phenomena in the past. Architectural sketches will make a clearly information about the old coastal line of Semarang. It is estimated that the seaport directly connected to the alun-alun / traditional square as central government. The city founders in Java puts the center of government using the same city spatial structure as waterfront city. The architecture remaining as a landmark of coastal city should be conserved.

    Full Text Available Large cities possess a sufficient potential to participate in the investment processes both at the national and international levels. A potential investor’s awareness of the possibilities and prospects of a city development is of a great importance for him or her to make a decision. So, providing a potential investor with relevant, laconic and reliable information, the local authorities increase the intensity of the investment process in the city economy and vice-versa. As a hypothesis, there is a proposition that a large city administration can sufficiently activate the investment processes in the economy of a corresponding territorial entity using the tools of the information providing. The purpose of this article is to develop measures for the improvement of the investment portal of a large city as an important instrument of the information providing, which will make it possible to brisk up the investment processes at the level under analysis. The reasons of the unsatisfactory information providing on the investment process in a large city economy are deeply analyzed; the national and international experience in this sphere is studied; advantages and disadvantages of the information providing of the investment process in the economy of the city of Makeyevka are considered; the investment portals of different cities are compared. There are suggested technical approaches for improving the investment portal of a large city. The research results can be used to improve the investment policy of large cities.

    As the city and urbanization’s accelerated pace has caused galloping population, the urban framework is extending with increasingly complex social problems. The urban management tends to become complicated and the governance seems more difficult to pursue. exploring the urban management’s new model has attracted local governments’ urgent attention. tcombines the guiding ideology and that management’s practices based on ecological theory, explains the Smarter city Ecology Managementmodel’s formation, makes modern urban management’s comparative analysis and further defines the aforesaid management mode’s conceptual model. Based on the smarter city system theory’s ecological carrying capacity, the author uses mathematical model to prove the coordination relationship between the smarter city Ecology Managementmode’s subsystems, demonstrates that it can improve the urban management’s overall level, emphasizes smarter city management integrity, believing that urban system’s optimization is based on each subsystem being optimized, attaching the importance to elements, structure, and balance between each subsystem and between internal elements. Through the establishment of the smarter city Ecology Managementmodel’s conceptual model and theoretical argumentation, it provides a theoretical basis and technical guidance to that model’s innovation.

    Full Text Available Purpose: Explanation of the essence and features of the “city placement” strategy, while observing the changes in “classic” forms of marketing communications used by cities and regions, including main pros and implementation procedures.Methodology: This paper is conceptual and relies on diagnosis and analysis of “city placement” strategy implementation in a chosen Polish city as well as on the author’s professional experiences. Analysis of scarce existing marketing literature, including the notion of “product placement,” allowed us to present model structures, variations, and rules that explain the role and pros of the “city placement” strategy in the promotion mix of places.Conclusions: This paper comprises not only a set of notions and models structuring the “city placement” phenomenon but also many operational concepts related to the implementation of this strategy, which makes this paper a valuable point in the discussion on innovative changes in the “promotion mix” of cities and regions.Originality: “city placement” is a novelty in promotion strategies of cities and regions. In the existing literaturę on place marketing, there are no in-depth conceptual works explaining the role, features, and forms of “city placement.” This paper is a new approach suggested by the author and is an attempt to explain the process.

    The purpose of this study was to observe trends in the number of restaurants and restaurant employees two years before and two years after the New York City Smoke-Free Air Act took effect in April, 1995. Between April 1993 and April 1997, New York City added 19,347 new restaurant jobs (18% increase) while the rest of the state outside the immediate metropolitan area added 7,423 new jobs (5% increase). The rate of growth in the number of restaurants was comparable among New York City, neighboring counties, and the rest of the state. The data suggest that the New York City Smoke-Free Air Act did not result in job losses for the city's restaurant industry.

  20. Definition of an Ontology Matching Algorithm for Context Integration in Smart Cities.

    Otero-Cerdeira, Lorena; Rodríguez-Martínez, Francisco J; Gómez-Rodríguez, Alma

    2014-12-08

    In this paper we describe a novel proposal in the field of smart cities: using an ontology matching algorithm to guarantee the automatic information exchange between the agents and the smart city. A smart city is composed by different types of agents that behave as producers and/or consumers of the information in the smart city. In our proposal, the data from the context is obtained by sensor and device agents while users interact with the smart city by means of user or system agents. The knowledge of each agent, as well as the smart city's knowledge, is semantically represented using different ontologies. To have an open city, that is fully accessible to any agent and therefore to provide enhanced services to the users, there is the need to ensure a seamless communication between agents and the city, regardless of their inner knowledge representations, i.e., ontologies. To meet this goal we use ontology matching techniques, specifically we have defined a new ontology matching algorithm called OntoPhil to be deployed within a smart city, which has never been done before. OntoPhil was tested on the benchmarks provided by the well known evaluation initiative, Ontology Alignment Evaluation Initiative, and also compared to other matching algorithms, although these algorithms were not specifically designed for smart cities. Additionally, specific tests involving a smart city's ontology and different types of agents were conducted to validate the usefulness of OntoPhil in the smart city environment.

    This paper addresses a major problem in international solid waste management, which is twofold: a lack of data, and a lack of consistent data to allow comparison between cities. The paper presents an indicator set for integrated sustainable waste management (ISWM) in cities both North and South, to allow benchmarking of a city's performance, comparing cities and monitoring developments over time. It builds on pioneering work for UN-Habitat's solid waste management in the World's cities. The comprehensive analytical framework of a city's solid waste management system is divided into two overlapping 'triangles' - one comprising the three physical components, i.e. collection, recycling, and disposal, and the other comprising three governance aspects, i.e. inclusivity; financial sustainability; and sound institutions and proactive policies. The indicator set includes essential quantitative indicators as well as qualitative composite indicators. This updated and revised 'Wasteaware' set of ISWM benchmark indicators is the cumulative result of testing various prototypes in more than 50 cities around the world. This experience confirms the utility of indicators in allowing comprehensive performance measurement and comparison of both 'hard' physical components and 'soft' governance aspects; and in prioritising 'next steps' in developing a city's solid waste management system, by identifying both local strengths that can be built on and weak points to be addressed. The Wasteaware ISWM indicators are applicable to a broad range of cities with very different levels of income and solid waste management practices. Their wide application as a standard methodology will help to fill the historical data gap. Copyright © 2014 Elsevier Ltd. All rights reserved.

    As an important theme in global climate change and urban sustainable development, the changes of land surface temperature (LST) and surface urban heat island (SUHI) have been more and more focused by urban ecologists. This study used land-use data to identify the urban-rural areas in 285 cities in China and comparatively analyzed LST in urban-rural areas with the perspective of spatial-temporal dynamics heterogeneity. The results showed that, 98.9% of the cities exhibited SUHI effect in summer nighttime and the effect was stronger in northern cities than that in southern cities. In 2010, the mean SUHI intensity was the largest in summer daytime, with 4.6% of the cities having extreme SUHI of over 4°C. From 2001 to 2010, the nighttime LST of most cities increased more quickly in urban areas compared with rural areas, with an increasing tendency of the urban-rural LST difference. The difference in the urban- rural LST change rate was concentrated in the range of 0-0.1°C/year for 68.0% of cities in winter and 70.8% of cities in summer. For the higher LST increasing in urban areas compared with rural areas, there were more cities in summer than winter, indicating that the summer nighttime was the key temporal period for SUHI management. Based on the change slope of urban-rural LST, cities were clustered into four types and the vital and major zones for urban thermal environment management were identified in China. The vital zone included cities in Hunan, Hubei and other central rising provinces as well as the Beibu Gulf of Guangxi Province. The major zone included most of the cities in Central Plain Urban Agglomeration, Yangtze River Delta and Pearl River Delta. These results can provide scientific basis for SUHI adaptation in China.

    Bangladesh is the most densely populated city in the whole world, which is visible more in the capital city Dhaka. People have to suffer and valuable times are being wasted for this chronic quandary. Lack of proper planning of the city, different speed vehicles on the same road, over population, inadequate road space, unplanned stoppage or parking etc. are responsible for causing the traffic congestion in Dhaka City. Among those insufficient/unplanned parking system is one of the main reasons for causing traffic congestion. The automated rotary car parking system is the best and suitable because of its less utilization of space compared to other systems. It is a friendly parking system due to the non-utilization of noise/pollution related mechanism. The aim of this paper is to develop an automated car parking system with a minimum cost for reducing congestion in Dhaka city.

  4. Energy sustainable cities. From eco villages, eco districts towards zero carbon cities

    Minimizing energy consumption is the effect of sustainable design technics as among many others: designing buildings with solar access and natural ventilation, using climate responsive design materials and effective insulation. Contemporary examples of zero-carbon cities: Masdar City, United Arab Emirates and Dongtan, China, confirm technical feasibility of renewable energy by implementation of solar PV and wind technologies. The ecological city - medium or high density urban settlement separated by greenspace causes the smallest possible ecological footprint on the surrounding countryside through efficient use of land and its resources, recycling used materials and converting waste to energy. This paper investigates the concept of energy sustainable cities, examines, how urban settlements might affect building energy design in eco-villages, eco-districts (e.g. Vauban, Freiburg in Germany, Bo01 Malmo in Sweden), and discuss the strategies for achieving Zero Emission Cities principles in densely populated areas. It is focused on low energy architectural design solutions which could be incorporated into urban settlements to create ecological villages, districts and cities, designed with consideration of environmental impact, required minimal inputs of energy, water, food, waste and pollution.

    I define big data with respect to its size but pay particular attention to the fact that the data I am referring to is urban data, that is, data for cities that are invariably tagged to space and time. I argue that this sort of data are largely being streamed from sensors, and this represents a sea change in the kinds of data that we have about what happens where and when in cities. I describe how the growth of big data is shifting the emphasis from longer term strategic planning to short-term thinking about how cities function and can be managed, although with the possibility that over much longer periods of time, this kind of big data will become a source for information about every time horizon. By way of conclusion, I illustrate the need for new theory and analysis with respect to 6 months of smart travel card data of individual trips on Greater London's public transport systems.

    is therefore to increase understanding of how city logistics emerge, and secondarily, to investigate whether such processes can be managed at all. Design/methodology/approach: – A paradigm shift in urban planning creates new ways of involving stakeholders in new sustainability measures such as city logistics...... dialectic forces were at play. City logistics schemes are still in an innovation phase. The biggest challenge in managing a process toward city logistics is to convince the many public and private stakeholders of their mutual interest and goals. Research limitations/implications: – Urban goods transport...... city logistics projects may fail. Thereby, cities become more environmentally and socially sustainable. Originality/value: – Insights into a city logistics project from a change management perspective has not previously been reported in literature....

    Cities are currently undergoing a transformation into the Smart concept, like Smartphones or SmartTV. Many initiatives are being developed in the framework of the Smart Cities projects, however, there is a lack of consistent indicators and methodologies to assess, finance, prioritize and implement this kind of projects. Smart Cities projects are classified according to six axes: Government, Mobility, Environment, Economy, People and Living. (Giffinger, 2007). The main objective of this research is to develop an evaluation model in relation to the mobility concept as one of the six axes of the Smart City classification and apply it to the Spanish cities. The evaluation was carried out in the 62 cities that made up in September 2015 the Spanish Network of Smart Cities (RECI- Red Española de Ciudades Inteligentes). This research is part of a larger project about Smart Cities’ evaluation (+CITIES), the project evaluates RECI’s cities in all the axes. The analysis was carried out taking into account sociodemographic indicators such as the size of the city or the municipal budget per inhabitant. The mobility’s evaluation in those cities has been focused in: sustainability mobility urban plans and measures to reduce the number of vehicles. The 62 cities from the RECI have been evaluated according to their degree of progress in several Smart Cities’ initiatives related to smart mobility. The applied methodology has been specifically made for this project. The grading scale has different ranks depending on the deployment level of smart cities’ initiatives. (Author)

  8. Securing water for the cities.

    1993-01-01

    Many cities in developing countries have grown so much that they can no longer provide adequate, sustainable water. Over pumping in Dakar and Mexico City has forced those cities to obtain water from ever more distant sources. In Dakar, the result has been saltwater intrusion. Overpumping has caused Mexico City to sink, in some areas by as much as 9 m, resulting in serious damage to buildings and sewage and drainage pipes. Other cities facing similar water problems are coastal cities in Peru (e.g., Lima), La Rioja and Catamarca in Argentina, cities in Northern Mexico, and cities in dry areas of Africa. For some cities, the problem is not so much ever more distant water supplies but insufficient funds to expand supplies. Bangkok and Jakarta both face saltwater intrusion into their overdrawn aquifers. Even through agriculture is the dominant user of water in most countries, demand concentrated in a small area exhausts local and regional sources and pollutes rivers, lakes, and coasts with untreated human and industrial waste. Most cities in Africa and Asia do not have a sewerage system. Further, most cities do not have the drains to deal with storm water and external floodwater, causing frequent, seasonal flooding. The resulting stagnant water provides breeding grounds for insect vectors of diseases (e.g., malaria). The problems in most cities are a result of poor management, not lack of water. Reducing leaks in existing piped distribution systems from the usual 60% loss of water to leaks to 12% would increase the available water 2-fold. Another way to address water shortages would be commercial, industrial, and recreational use of minimally treated waste water, such as is the case in Madras and Mexico City. Political solutions are needed to resolve inadequate water supply and waste management.

  9. Cities and Energy Consumption: a Critical Review

    Directory of Open Access Journals (Sweden)

    Carmela Gargiulo

    2017-12-01

    Full Text Available The relationship between cities and energy consumption has been of great interest for the scientific community for over twenty years. Most of the energy consumption, indeed, occurs in cities because of the high concentration of human activities. Thus, cities are responsible for a big share of carbon dioxide emissions (CO2. However, the debate on this topic is still open, mainly because of the heterogeneity of published studies in the selection, definition and measurement of the urban features influencing energy consumption and CO2 emissions, as well as in the choice of the energy sectors to be considered, in the territorial scale of analysis, and in the geographical distribution of the sample. Therefore, the goal of this research is to systematize and compare the approach, methodology and results of the relevant literature on the relationship between cities and energy consumption over the last twenty years. Furthermore, this critical review identifies the knowledge gap between what is known and what is still under debate and, based on that, it proposes a conceptual framework that will help to outline a new direction for future research and support local policy makers in the definition of strategies and actions that can effectively reduce urban energy use and CO2 emissions.

    Here we sketch the rudiments of what constitutes a smart city which we define as a city in which ICT is merged with traditional infrastructures, coordinated and integrated using new digital technologies. We first sketch our vision defining seven goals which concern: developing a new understanding of urban problems; effective and feasible ways to coordinate urban technologies; models and methods for using urban data across spatial and temporal scales; developing new technologies for communication and dissemination; developing new forms of urban governance and organisation; defining critical problems relating to cities, transport, and energy; and identifying risk, uncertainty, and hazards in the smart city. To this, we add six research challenges: to relate the infrastructure of smart cities to their operational functioning and planning through management, control and optimisation; to explore the notion of the city as a laboratory for innovation; to provide portfolios of urban simulation which inform future designs; to develop technologies that ensure equity, fairness and realise a better quality of city life; to develop technologies that ensure informed participation and create shared knowledge for democratic city governance; and to ensure greater and more effective mobility and access to opportunities for urban populations. We begin by defining the state of the art, explaining the science of smart cities. We define six scenarios based on new cities badging themselves as smart, older cities regenerating themselves as smart, the development of science parks, tech cities, and technopoles focused on high technologies, the development of urban services using contemporary ICT, the use of ICT to develop new urban intelligence functions, and the development of online and mobile forms of participation. Seven project areas are then proposed: Integrated Databases for the Smart City, Sensing, Networking and the Impact of New Social Media, Modelling Network Performance

    2015-01-01

    In the twenty-first century, the population in China will be increasingly urbanized – focusing the sustainability challenge on cities and raising new challenges to address the urban resilience capacity. During the past two decades, China’s urban policies are state institution-directed, growth-oriented, and land-based, imposing unprecedented challenges on sustainability. Strengthening the capacity of cities to manage resilience appears to be a key factor for cities to effectively pursue sustainable development. The aim of this paper is to explore strategic planning approaches for creating resilient cities in China through a study on Hangzhou City in an integrated framework. Firstly, the paper gives a systematic insight into the structure of Hangzhou City. Secondly, the development trajectory of the urban system is analyzed to understand how the past has shaped the present and to get a broader perspective on its evolution. Thirdly, scenario planning is conducted to explore the adaptive capacity of Hangzhou City under different future conditions. At last, having analyzed the past, present, and future of the urban system, the paper discusses the strategies for resilient planning, which helps to identify factors and trends that might enhance or inhabit the adaptability.

    Lugaric, Luka; Krajcar, Slavko

    2016-01-01

    Recognized as implementation actors of operative measures for transition towards a low carbon economy, cities must establish a development roadmap integrating local resources with local energy development plans. A systematic approach does not exist yet and cities develop their plans individually, which is difficult for small and medium sized cities due to limited development capacities. Conventional city planning approaches do not integrate considerations on energy, economy and environment in transition plans in an easily comparable way, yet making decisions with regards to these parameters is vital to determine outcomes of planned developments on future sustainability of the city. The paper presents a framework model based on emergy synthesis which integrates energy, economic and environmental city systems in the decision making process, examining associated theoretical challenges and application limitations. The method is applied on the city of Sisak in Croatia which has developed plans to implement several initiatives geared towards creating a smart energy city. The model enables simulation and assessment of impacts of individual projects targeting the development of a smart energy city on city sustainability expressed through emergy performance, used as a tool for evaluating local development alternatives within the boundary of local resources. - Highlights: • Key concepts of present city development trends towards sustainability are examined. • Emergy synthesis is examined and applied as a tool for policy and decision makers. • Emergy model of a small city is developed, along with submodels for renewable energy sources and buildings. • Simulation of 5 different projects shows impacts on overall city sustainability in a comparable manner. • Increase in emergy sustainability index is confirmed after presumed implementation of simulated projects.

    Just as hard as describing the city of today, describing the city of tomorrow represents a real challenge. Energy Cities is active at both local and European levels, therefore we will only address the European-type cities in our reflection. Central to the vision of Energy Cities is of course the (sustainable and livable) energy issue. Therefore, our starting point is the consideration of energy issue as an essential component of urban and regional development as well as an excellent scanner of how the city and its periphery/region are organised. In 2050, cities will not look that much different than those of the beginning of the century. However, a lot of invisible radical changes will have occurred. These changes are already underway in an increasing number of cities, especially some which are committed with the Covenant of Mayors. These are 'weak signals' that pave the way for tomorrow. This paper aims at understanding these logics and at showing up paths of improvement in the domains of energy supply, urban form, buildings, mobility, public space, economy, consumption, governance, local authorities, multilevel governance and Territorial cohesion, quality of Life, peace and security

    The Air Quality Standards for Particulate Matter (PM) at high altitude urban areas in different countries, must consider the pressure and temperature due to the effect that these parameters have on the breath volume. This paper shows the importance to correct Air Quality Standards for PM considering pressure and temperature at different altitudes. Specific factors were suggested to convert the information concerning PM, from local to standard conditions, and adjust the Air Quality Standards for different high altitudes cities. The correction factors ranged from: 1.03 for Santiago de Chile to 1.47 for El Alto Bolivia. Other cities in this study include: Mexico City, México; La Paz, Bolivia; Bogota, Cali and Medellin, Colombia; Quito, Ecuador and Cuzco, Peru. If these corrections are not considered, the atmospheric concentrations will be underestimated. - Highlights: ► AQS for particulate matter concentrations adjusted by pressure and temperature. ► Particulate matter concentrations can be underestimated in high altitude Cities. ► Particulate matter concentrations must be compared under the same conditions. - In order to compare high altitude atmospheric PM concentrations with AQS, one must consider T and P of the sampling site.

  1. Internal migration and occupational achievement in Mexico city

    Full Text Available The purpose of this work is to analyze the effect of migration status on labor market insertion and occupational achievement. It is of interest to know whether the observed differences between people with a different migration status (from first-generation rural migrants to natives are due to their migratory condition per se or other sociodemographic variables associated with their status that could put migrants at disadvantage in the labor market of Mexico City. We elaborate on this by using data from the Survey on Inequality and Social Mobility in Mexico City, 2009. Unlike studies of major Mexican cities during the import substitution model, wich as sumed that upward occupational mobility rates benefited almost equally the born and raised in the city and the rural migrants our results suggest the opposite: that migrants do poorly, but not for the fact that they are migrants, but because they tend to have lower economic, cultural and social capital attributes in their families of origin due to certain factors that leave them unable to capitalize on their efforts to achieve an educational and occupational performance similar or superior to that of the natives. A suggestive finding is that, even after controlling for the disadvantageous social background, female rural migrants show a consistently unfavorable performance when compared to the native women of Mexico City.

    Full Text Available Cultural tourism associates itself with complex issues of dealing with urban memory. As a connotative communication channel, tourism sites and monuments are a perspective through which a city speaks for itself. A number of tourist destinations in the former GDR state faced drastic changes in their tourism management after the national unification of Germany. Which voice does the cultural heritage contain in these cities along its dissonant history and how the local perceptions on the heritage have been altered in the last 25 years are the main subjects of this research. Based on the former studies on the topic of 'heritage and urban identity', this paper explores the relation between architectural heritage management and the dwellers' perceptions on the heritage since the removal of visa controls between GDR and BDR in 1989. Compared to the economic and political studies after the German reunification, socio-cultural issues on local identity and cultural re-adaption process have not been much discussed. Taking three exemplary cities in Thuringia (Eisenach, Gotha and Weimar, the document analysis of the conceptual changes in cultural tourism management and qualitative interviews on both authorities and residents will be done. By providing empirical data on the ongoing German governance, the author attempts to explore the role of cultural heritage in Germany's urban resilience. Furthermore, this research aims to contribute to the contemporary agenda on cultural tourism management in multi-identity societies over international borders.

    Atmospheric corrosion is a significant problem given destruction of various materials, especially metals. The corrosion investigation in the industrial city environment was carried out during one year exposure. Corrosion potential was determined using the potentiometric method. The highest effect of corrosion processes was observed during the winter season due to increased air pollution. Corrosion of samples pre-treated in tannic acid before the exposure was more difficult compared with the samples without pretreatment. The corrosion products determined with the SEM/EDS method prove that the most corrosive pollutants present in the industrial city air are SO2, CO2, chlorides and dust.

    To examine whether physician social networks are associated with variation in treatment for men with localized prostate cancer. 2004-2005 Surveillance, Epidemiology and End Results-Medicare data from three cities. We identified the physicians who care for patients with prostate cancer and created physician networks for each city based on shared patients. Subgroups of urologists were defined as physicians with dense connections with one another via shared patients. Subgroups varied widely in their unadjusted rates of prostatectomy and the racial/ethnic and socioeconomic composition of their patients. There was an association between urologist subgroup and receipt of prostatectomy. In city A, four subgroups had significantly lower odds of prostatectomy compared with the subgroup with the highest rates of prostatectomy after adjusting for patient clinical and sociodemographic characteristics. Similarly, in cities B and C, subgroups had significantly lower odds of prostatectomy compared with the baseline. Using claims data to identify physician networks may provide an insight into the observed variation in treatment patterns for men with prostate cancer. © Health Research and Educational Trust.

    A smart city implies a consistent use of technology for the benefit of the community. As the city develops over time, components and subsystems such as smart grids, smart water management, smart traffic and transportation systems, smart waste management systems, smart security systems, or e-governance are added. These components ingest and generate a multitude of structured, semi-structured or unstructured data that may be processed using a variety of algorithms in batches, micro batches or in real-time. The ICT architecture must be able to handle the increased storage and processing needs. When vertical scaling is no longer a viable solution, Hadoop can offer efficient linear horizontal scaling, solving storage, processing, and data analyses problems in many ways. This enables architects and developers to choose a stack according to their needs and skill-levels. In this paper, we propose a Hadoop-based architectural stack that can provide the ICT backbone for efficiently managing a smart city. On the one hand, Hadoop, together with Spark and the plethora of NoSQL databases and accompanying Apache projects, is a mature ecosystem. This is one of the reasons why it is an attractive option for a Smart City architecture. On the other hand, it is also very dynamic; things can change very quickly, and many new frameworks, products and options continue to emerge as others decline. To construct an optimized, modern architecture, we discuss and compare various products and engines based on a process that takes into consideration how the products perform and scale, as well as the reusability of the code, innovations, features, and support and interest in online communities.

    2018-03-01

    In this study, information extracted from the first global urban fluvial flood risk data set (Aqueduct) is investigated and visualized to explore current and projected city-level flood impacts driven by urbanization and climate change. We use a novel adaption of the self-organizing map (SOM) method, an artificial neural network proficient at clustering, pattern extraction, and visualization of large, multi-dimensional data sets. Prevalent patterns of current relationships and anticipated changes over time in the nonlinearly-related environmental and social variables are presented, relating urban river flood impacts to socioeconomic development and changing hydrologic conditions. Comparisons are provided between 98 individual cities. Output visualizations compare baseline and changing trends of city-specific exposures of population and property to river flooding, revealing relationships between the cities based on their relative map placements. Cities experiencing high (or low) baseline flood impacts on population and/or property that are expected to improve (or worsen), as a result of anticipated climate change and development, are identified and compared. This paper condenses and conveys large amounts of information through visual communication to accelerate the understanding of relationships between local urban conditions and global processes.

    During March of 2006 we participated in MILAGRO (Megacities Initiative: Local and Global Research Observations), a multi-platform campaign to measure pollutants in and in outflow from the Mexico City metropolitan area. As part of MILAGRO we collected whole air canister samples at two Mexico City ground sites: the Instituto Mexicano del Petroleo, located in the city, northeast of the center, and the Universidad Technologica de Tecamac, a suburban site approximately 50 km northeast of the city center. Samples were also collected in various other locations throughout Mexico City. Over 300 whole air samples were collected and analyzed for a wide range of volatile organic compounds (VOCs) including methane, carbon monoxide, nonmethane hydrocarbons (NMHCs) and halocarbons. Propane was the most abundant NMHC at both the urban and suburban locations, with mixing ratios frequently in excess of 10 parts per billion at both locations. This is likely the result of the widespread use of liquefied petroleum gas (LPG) of which propane is the major component. For most species, median mixing ratios at the urban sites were significantly greater than at the suburban site. Here we compare results from both urban and suburban locations and also examine the influence of transport on the composition of outflow from Mexico City.

    Full Text Available The research in this paper is devoted to analysis of budget items for the city of Belgrade, to revenues and earnings, expenses and issuance for 2013, 2014 and 2015 in order to determine changes in the structure and in time, and, based on these, the appropriate conclusions were drawn, which can serve as recommendations for creating budgets in the future. One of the key problems in public procurement at the City of Belgrade level were significant differences in prices for the same items procured by different contracting authorities. In many cases the same bidder offered the very same items at prices which differed up to 50% to different contracting authorities at the city level. That was a signal for the city administration to centralize the procurement of certain items in 2015 achieving significant reduction in prices of bundled procurement compared to the ones undertaken by different contracting authorities previously. In this context, the subject of the second part of this paper will be devoted to the importance of centralization of public procurements in the segment where it is possible to achieve efficiency in the management of budget funds.

    Full Text Available Cities are living entities that change almost daily but its people are aware of it. They forget the state before the great changes and people become accustomed to the new urban image. In a hundred years a city can completely change its appearance and even its essence. This is the case of Granada, where its historic center was heavily modified during the nineteenth century. These changes have been studied by a project analyzing and virtually rebuilding the historic city. The work ranges from the Rey Chico, below the Alhambra palace, to Puerta Real, restoring the image of the city around 1831, based on the engravings and descriptions of romantic travelers, on the previous alignments and transformations in old pictures.

    The Department of Energy's Clean Cities program was created in 1993 to reduce petroleum usage in the transportation sector. The program promotes alternative fuels such as biofuels and fuel-saving strategies such as idle reduction and fleet management through coalitions of local government, non-profit, and private actors. Few studies have evaluated the impact of the program because of its complexity that include interrelated strategies of grants, education and training and diversity of participants. This paper uses a Difference-in-Differences (DiD) approach to evaluate the effectiveness of the program between 1990 and 2010. We quantify the effectiveness of the Clean Cities program by focusing on performance measures such as air quality, number of alternative fueling stations, private vehicle occupancy and transit ridership. We find that counties that participate in the program perform better on all these measures compared to counties that did not participate. Compared to the control group, counties in the Clean Cities program experienced a reduction in days with bad air quality (3.7%), a decrease in automobile commuters (2.9%), an overall increase in transit commuters (2.1%) and had greater numbers of new alternative fueling stations (12.9). The results suggest that the program is a qualified success. Copyright © 2016 Elsevier B.V. All rights reserved.

    City environmental conditions are associated with health outcomes in people living there. World Health Organization (WHO) initiated Healthy City in 1986. To promote the networking, Alliance for Healthy Cities (AFHC) was launched in 2003 with local offices including AFHC Japan. As of 2010, 26 cities are members of AFHC Japan. A questionnaire was sent to those member cities. It includes questions on why they became an AFHC member, which section is in charge of the initiatives, what factors are important for promotion, and others. Out of the 26 cities, 13 cities returned the completed questionnaire. As for factors important for promoting the initiatives, 10 (77%) out of the 13 cities answered "consciousness of residents", while five (38%) chose "budget". This result suggests that community participation is a more important factor than budget for promoting and succeeding in the initiatives. Aging is a problem in any of the member cities, and six cities out the 13 falls under the category of superaged society, which is defined as a society with the proportion of aged people cities (85%) agreed that bicycles are an alternative means of transportation to cars; however, infrastructure for ensuring safety needs further improvement. In the promotion of Healthy City, networking among the member cities in Japan and worldwide should be promoted. Community participation with empowerment from the planning stage should lead to sustainable initiatives. The function of AFHC in collaboration among the members should be strengthened to cope with the rapidly changing city environment.

    2017-10-01

    This article proposes to make a comparative bioclimatic analysis from 1990 to 2014 of the main square of Antofagasta, a coastal desert city in Chile, which was remodelled in 1995, and shows how the redesigning of green areas affects the microclimatic conditions and thermal comfort of the urban space. Ex ante measurements dating 1990 were compared with ex post results from 2014. Data were obtained in both cases in the month of September at different times of a day and in different climate conditions. The variables studied were: land surface temperature, humidity, wind speed, amount of light and square use frequency inside the square and in surrounding streets. The temperatures are not statistically different during the years 1990 and 2014 for the city of Antofagasta. The main layout of the square has not changed, and inside the square it is similar for both periods, but new species were introduced and bigger trees with shadow projection were cut down. The square had a micro-climate role in 2014 as well as in 1990. The highest frequency zone with an important surface lost it is comfort thermic condition with an increase of 1°C. Other smaller zones with less relevance for users gained in cooling with a 0.5°C reduction. The new design has been detrimental to the intensity of its micro climatic regulatory function affecting the thermic comfort of the square’s internal spaces, especially those formerly protected by shadow, which mitigate a high solar radiation. The study results suggest that bio-climatic analysis of public open spaces is a key component for the design of future projects as a heat mitigating tool in the context of climate change. Research question is: How does the redesign of the square impact a cool urban island and the thermic comfort of users? Significant differences between data in situ collected in 1990 and 2014. Thermal comfort was negatively affected by the redesign in the square. The square is still a cool island but with less strength.

  1. Smart Cities as Organizational Fields: A Framework for Mapping Sustainability-Enabling Configurations

    Directory of Open Access Journals (Sweden)

    Paul Pierce

    2017-08-01

    Full Text Available Despite the impressive growth of smart city initiatives worldwide, an organizational theory of smart city has yet to be developed, and we lack models addressing the unprecedented organizational and management challenges that emerge in smart city contexts. Traditional models are often of little use, because smart cities pursue different goals than traditional organizations, are based on networked, cross-boundary activity systems, rely on distributed innovation processes, and imply adaptive policy-making. Complex combinations of factors may lead to vicious or virtuous cycles in smart city initiatives, but we know very little about how these factors may be identified and mapped. Based on an inductive study of a set of primary and secondary sources, we develop a framework for the configurational analysis of smart cities viewed as place-specific organizational fields. This framework identifies five key dimensions in the configurations of smart city fields; these five dimensions are mapped through five sub-frameworks, which can be used both separately as well as for an integrated analysis. Our contribution is conceived to support longitudinal studies, natural experiments and comparative analyses on smart city fields, and to improve our understanding of how different combinations of factors affect the capability of smart innovations to translate into city resilience, sustainability and quality of life. In addition, our results suggest that new forms of place-based entrepreneurship constitute the engine that allows for the dynamic collaboration between government, citizens and research centers in successful smart city organizational fields.

    Full Text Available It has been a century since the first Garden Cities at Welwyn and Letchworth were founded and, in the eyes of many, we have entered the age of the Smart City. This commentary briefly reflects upon the origins of Ebenezer Howard’s vision in the slums of overcrowded, filthy London and the fire-traps of early 20th century Chicago before outlining some of the main contributing factors to its ultimate failure as an approach: the lack of a robust theory underpinning his ideas, a finance model which was unacceptable to the banks—leading to a compromise which robbed the more idealistic participants of any real power over their schemes—and finally, a dilution of Howard’s vision by architects who were more focused on population density than on social reform. A parallel is then drawn between the weaknesses which afflicted the Garden City vision, and those which afflict current Smart City visions, a loose agglomeration of ahistorical techno-utopian imaginaries, whose aims almost invariably include optimising various measures of efficiency using large-scale deployments of networked sensors and cameras, linked to monolithic control rooms from which our shared urban existence is overseen. The evolution (or perhaps more accurately: alteration of these concepts in response to criticism is then detailed, before some of the less well-known ideas which are now emerging are briefly discussed.

The problem is when these goals and these procedures are considered able to generate an architectural form, or when considered sufficient to return quality to the city. An urban quality that derives from "efficiency" makes think more about dystopia of Fritz Lang's Metropolis that utopia of the New City of Sant'Elia.

    Anthropogenic heating from building energy use, vehicle fuel consumption, and human metabolism is a key term in the urban energy budget equation. Heating from human metabolism, however, is often excluded from urban energy budgets because it is widely observed to be negligible. Few reports for low-latitude cities are available to support this observation, and no reports exist on the contribution of domestic animals to urban heat budgets. To provide a more comprehensive view of metabolic heating in cities, we quantified all terms of the anthropogenic heat budget at metropolitan scale for the world's 26 largest cities, using a top-down statistical approach. Results show that metabolic heat release from human populations in mid-latitude cities (e.g. London, Tokyo, New York) accounts for 4-8% of annual anthropogenic heating, compared to 10-45% in high-density tropical cities (e.g. Cairo, Dhaka, Kolkata). Heat release from animal populations amounts to <1% of anthropogenic heating in all cities. Heat flux density from human and animal metabolism combined is highest in Mumbai—the world's most densely populated megacity—at 6.5 W m-2, surpassing heat production by electricity use in buildings (5.8 W m-2) and fuel combustion in vehicles (3.9 W m-2). These findings, along with recent output from global climate models, suggest that in the world's largest and most crowded cities, heat emissions from human metabolism alone can force measurable change in mean annual temperature at regional scale.

    Full Text Available The virtual city exists in “time” whereas the real city exists in “space”. The first one is an expression of our imagination, the second one of our ability to create. Time has articulated the images of cities as artisan philosophers, historians, artists, dreamers and even poets have given it to us. Space has generated cities which have been worked upon by geographers, geologists, surveyors, and finally urban planners. Space and time however live together in both cities, even if with alternating states of subordination. The culture of thinking, of decision making and of working is the unifying center of both the cities; it is the generating element both of the crises and the prosperity of the cities and it works towards an overcoming of the first and for the pursuit of the second (prosperity using the experience of the past for the making of a better future.

    This report is designed to help city authorities evaluate and prioritize more than 70 different policy strategies that can reduce their city’s energy use and carbon-based greenhouse gas emissions of carbon dioxide (CO2) and methane (CH4). Local government officials, researchers, and planners can utilize the report to identify policies most relevant to local circumstances and to develop a low carbon city action plan that can be implemented in phases, over a multi-year timeframe. The policies cover nine city sectors: industry, public and commercial buildings, residential buildings, transportation, power and heat, street lighting, water & wastewater, solid waste, and urban green space. See Table 1 for a listing of the policies. Recognizing the prominence of urban industry in the energy and carbon inventories of Chinese cities, this report includes low carbon city policies for the industrial sector. The policies gathered here have proven effective in multiple locations around the world and have the potential to achieve future energy and carbon savings in Chinese cities.

  12. Eco-Environmental Factors in Green Roof Application in Indian Cities

    Mukherjee, M.

    2014-09-01

    Green-roof is the cost-effective environmental mitigation strategy for urban areas [1]. Its application is limited in India primarily due to inadequate understanding about its cost-benefit analysis and technicalities of its maintenance. Increasing awareness about green roof can alter conservative attitude towards its application. So, this work presents a quantified study on green-roof types, cost and environmental benefits while considering different geo-urban climate scenarios for cities of Kolkata, Mumbai, Chennai and New Delhi. Cost estimation for extensive and intensive green-roof with reference to commonly used roof in urban India is also worked out. Attributes considered for environmental discussion are energy savings related to thermal heat gain through roof, roof-top storm-water drainage and sound attenuation. The comparative study confirms that further focused study on individual cities would identify city-specific objectives for green-roof application; strategies like awareness, capacity building programmes, incentives, demonstration projects etc. can be worked out accordingly for wider application of green-roof in Indian cities.

    2016-09-01

    Intersectoral collaboration (ISC) is important in the health field because the complexity of determinants of health makes it difficult for one institution to resolve all health issues. Promotion of physical activity can especially benefit from a multi-sectoral approach. Despite so much emphasis on its importance in both primary health and health promotion, ISC has been underachieved in the field. This study aimed to examine the characteristics and level of ISC among physical activity programs in Healthy Cities as compared to non-Healthy Cities. I conducted a postal survey where 24 people from Healthy Cities and 72 people from non-Healthy Cities participated. The survey included questions to measure the level of ISC as well as to determine ISC partners and activities. Among the entire 393 physical activity programs, 336 (85.5%) had some kind of collaboration with one or more partners. The percentage having one or more partners was greater in Healthy Cities than in non-Healthy Cities. However, there were no statistical differences between the two groups in terms of the level of ISC within a municipal organization. Collaboration activities of the other departments were mostly supportive, such as providing a venue, recruiting participants and publicizing, and other kinds of administrative support. To strengthen ISC in Korean Healthy Cities, various actions including providing a legal basis, specific and substantive supports, financial incentives, and organizational recognitions will be helpful as well as the development of partnerships with other departments in urban planning, transport, urban design, and communication. © The Author 2015.

    Vatican City, the administrative and spiritual capital of the Roman catholic Church, has a population of 1000. Citizenship is generally accorded only to those who reside in Vatican City for reasons of office of employment. Supreme legislative, executive, and judicial power is currentily exercised by Pope John Paul II, the 1st non-italian pope in 5 centuries. The State of Vatican City is recognized by many nations as an independent sovereign state under the temporal jurisdiction of the Pope. By 1984, 108 countries had established diplomatic relations with the Holy See, most of which are not Roman Catholic. Third World countries comprise a large proportion of countries that have recently established relations with the Holy See. The US re-established relations with the Vatican in 1984 and there is frequent contact and consultation between the 2 states on key international issues.

    Full Text Available Street patterns of Israeli cities were investigated by comparing three time periods of urban development: (I the late 19th century until the establishment of the state of Israel in 1948; (II 1948 until the 1980s; and (III the late 1980s until the present. These time periods are related respectively to the pre-modern, modern and late-modern urban planning approach. Representative urban street networks were examined in selected cities by means of morphological analysis of typical street pattern properties: curvature, fragmentation, connectivity, continuity and differentiation. The study results reveal significant differences between the street patterns of the three examined periods in the development of cities in Israel. The results show clearly the gradual trends in the intensification of curvature, fragmentation, complexity and hierarchical organization of street networks as well as the weakening of the network's internal and external connectivity. The implications of these changes on connectivity and spatial integration are discussed with respect to planning approaches.

    Ding, Z.; Romanelli, F.; Chen, Y. T.; Panza, G. F.

    Algorithms for the calculation of synthetic seismograms in laterally heterogeneous anelastic media have been applied to model the ground motion in Beijing City. The synthetic signals are compared with the few available seismic recordings (1998, Zhangbei earthquake) and with the distribution of observed macroseismic intensity (1976, Tangshan earthquake). The synthetic three-component seismograms have been computed for the Xiji area and Beijing City. The numerical results show that the thick Tertiary and Quaternary sediments are responsible for the severe amplification of the seismic ground motion. Such a result is well correlated with the abnormally high macroseismic intensity zone in the Xiji area associated with the 1976 Tangshan earthquake as well as with the ground motion recorded in Beijing city in the wake of the 1998 Zhangbei earthquake.

    Full Text Available This paper explores smart city planning and development shortcomings. In particular, it investigates eleven cases of smart city strategies and the shortcomings that were observed during their planning and implementation stages. The cases include: Barcelona Smart City, PlanlT Valley, Stockholm Smart City, Cyberjaya, King Abdullah Economic City, Masdar City, Skolkovo, Songdo International Business District, Chicago Smart City, Rio de Janeiro Smart City, and Konza Technology City. The paper proceeds with the synthesis of the findings and their critical appraisal. Shortcomings are classified into economic and budget shortages, bureaucratic and organizational challenges, challenges in the development and layout of digital services, poor physical planning, struggle to attract investment and support the development of new businesses, low performance in attracting and engaging users, and stakeholder resistance. In turn, the shortcomings are clustered in two distinct groups and analyzed in terms of causes and effects. The paper closes with mitigation propositions, accounting for past experience and novel approaches to this end.

  1. Staying in the Global City: Patterns of Luxury Hotel Localization in Santiago de Chile

    2016-07-01

    Full Text Available Chile, for a long time a backwater of international tourism, is about to turn itself into a top–end destination, with the capital Santiago taking a leading role. In recent decades, international chains have constructed numerous luxury hotels aimed at the requirements of international city and business tourists. The continuing bicentric orientation of the city (core city and ‘modern town’, which has withstood all fragmentation processes, has led to a polycentric distribution of luxury hotels, with the largest, most expensive and most luxurious hotels situated in the ‘modern town’. The airport, the innovation centers and business parks, as well as the city center, have also seen investment. When compared with models of hotel localization in cities, it is evident that Santiago has overcome the traditional model of city tourism under the influence of globalization trends. Today the needs of global travelers, both city and business tourists, transport links and the surroundings of the hotels play an important role. This is reflected in the pricing structure and the distribution of luxury hotels across the city.

    2017-06-01

    Full Text Available Since the 1980s, within the broader context of studies on smart cities, there has been a growing body of academic research on networked cities and “computable cities” by authors including Manuel Castells (Castells, 1989; Castells & Cardoso, 2005, William Mitchell (1995, Michael Batty (2005, 2013, and Rob Kitchin (2011. Over the last decade, governments in Asia have displayed an appetite and commitment to construct large scale city developments from scratch—one of the most infamous being the smart entrepreneurial city of Songdo, South Korea. Using Songdo as a case study, this paper will examine, from an urban systems perspective, some of the challenges of using a green-city model led by networked technology. More specifically, this study intends to add to the growing body of smart city literature by using an external global event—the global financial crisis in 2008—to reveal what is missing from the smart city narrative in Songdo. The paper will use the definition of an urban system and internal subsystems by Bertuglia et al. (1987 and Bertuglia, Clarke and Wilson (1994 to reveal the sensitivity and resilience of a predetermined smart city narrative. For instance, what happens if the vision moves from the originally intended international-orientated population towards remarketing the city to attract a domestic middle-class population. The lens of the financial crisis in 2008 revealed that the inherent inflexibility of a closed-system approach in Songdo was not sufficiently resilient to external shocks. The shift towards a domestic middle-class population revealed the inequality in accessing the city services in a system designed with formalized and rigid inputs and outputs. By focusing predominantly on technology, the social dimensions of the city were not part of Songdo’s smart city vocabulary. Therefore, in adopting a technologically deterministic approach (Mullins & Shwayri, 2016 to achieving efficiency and combating environmental

    Studies confirm that the risk of exposure to indor radon is attributable to lung cancer worldwide. The relationship between radon exposure and cancer is a linear one which necessitates for need for measurements of indoor radon concentration. This paper presents the results of measurements of indoor radon in several libya cities using CR-39 plastic. The results showed that the average radon concentration in the cities of Tripoli, Al-harcha and Alrajaban were 48.8 Bg/m 3 , 51.4 Bg/m 3 and 55.5 Bg/m 3 respectively. The average indoor radon concentration in Libya is low comparing with other studies. (Author)

    2015-06-01

    Full Text Available Atmospheric corrosion is a significant problem given destruction of various materials, especially metals. The corrosion investigation in the industrial city environment was carried out during one year exposure. Corrosion potential was determined using the potentiometric method. The highest effect of corrosion processes was observed during the winter season due to increased air pollution. Corrosion of samples pre-treated in tannic acid before the exposure was more difficult compared with the samples without pretreatment. The corrosion products determined with the SEM/EDS method prove that the most corrosive pollutants present in the industrial city air are SO2, CO2, chlorides and dust.

    2012-08-01

    Real-time measurements of ambient concentrations of gas-phase ammonia (NH3) were performed in Barcelona (NE Spain) in summer between May and September 2011. Two measurement sites were selected: one in an urban background traffic-influenced area (UB) and the other in the historical city centre (CC). Levels of NH3 were higher at CC (5.6 ± 2.1 μg m-3 or 7.5 ± 2.8 ppbv) compared with UB (2.2 ± 1.0 μg m-3 or 2.9 ± 1.3 ppbv). This difference is attributed to the contribution from non-traffic sources such as waste containers, sewage systems, humans and open markets more dense in the densely populated historical city centre. Under high temperatures in summer these sources had the potential to increase the ambient levels of NH3 well above the urban-background-traffic-influenced UB measurement station. Measurements were used to assess major local emissions, sinks and diurnal evolution of NH3. The measured levels of NH3, especially high in the old city, may contribute to the high mean annual concentrations of secondary sulfate and nitrate measured in Barcelona compared with other cities in Spain affected by high traffic intensity. Ancillary measurements, including PM10, PM2.5, PM1 levels (Particulate Matter with aerodynamic diameter smaller than 10 μm, 2.5 μm, and 1 μm), gases and black carbon concentrations and meteorological data, were performed during the measurement campaign. The analysis of specific periods (3 special cases) during the campaign revealed that road traffic was a significant source of NH3. However, its effect was more evident at UB compared with CC where it was masked given the high levels of NH3 from non-traffic sources measured in the old city. The relationship between SO42- daily concentrations and gas-fraction ammonia (NH3/(NH3 + NH4+)) revealed that the gas-to-particle phase partitioning (volatilization or ammonium salts formation) also played an important role in the evolution of NH3 concentration in summer in Barcelona.

    2013-01-01

    Resource-based cities in China have made momentous contributions to the development of the national economy for decades. However, with the depletion of natural resources, their sustainable development is challenging and transition is important. The Chinese government has made great efforts to help resource-based cities. The purpose of this study is to investigate transition policies and their implementation. Firstly, we reviewed previous studies and summarized the essential elements of some successful resource-based cities, which are useful experiences for Chinese resource-based cities. Secondly, we studied the development of resource-based cities over the past 10 years with a focus on economic development, industrial structure, government revenue and environmental conditions. We found that resource-based cities were less developed compared to other cities. The main reasons are the after-effects of a planned economy, an unreasonable tax system, planning mistakes and misguided resources exploitation policies. Thirdly, we analyzed several aspects of the policy responses after the introduction of transition policies, including designating 69 resource-exhausted cities, supporting cities with funds and projects, formulating transition plans and evaluating transition performance. However, there are some deficiencies in the process of policy implementation. Finally, some recommendations were provided to improve transition performance and sustainable development for resource-based cities. - Highlights: ► Analyze the development of Chinese resource-based cities from four aspects. ► Analyze the causes of less development in resource-based cities. ► Investigate policies and their responses to transformation. ► Provide recommendations to improve transformation performance and sustainable development

The presented study shows that younger students and young adolescents compared to adult citizens have the basic social competence in the identification of dangerous and scary places in the city. Interpretive matrix of children for determining the "worst places" formed irrational and non-reflexive. The most significant differences between adults and children of city in the way they describe the Stranger in the city (which is assessed as dangerous Stranger.

  14. The Flickering Global City

    Directory of Open Access Journals (Sweden)

    Eric Slater

    2015-08-01

    Full Text Available This article explores new dimensions of the global city in light of the correlation between hegemonic transition and the prominence of financial centers. It counterposes Braudel’s historical sequence of dominant cities to extant approaches in the literature, shifting the emphasis from a convergence of form and function to variations in history and structure. The marked increase of finance in the composition of London, New York and Tokyo has paralleled each city’s occupation of a distinct niche in world financial markets: London is the principal center of currency exchange, New York is the primary equities market, and Tokyo is the leader in international banking. This division expresses the progression of world-economies since the nineteenth century and unfolds in the context of the present hegemonic transition. By combining world-historical and city-centered approaches, the article seeks to reframe the global city and overcome the limits inherent in the paradigm of globalization.

    This paper presents the biocorrosion of city sewer collectors impregnated with special polymer sulphur binders, polymerized sulphur, which is applied as the industrial waste material. The city sewer collectors are settled with a colony of soil bacteria which have corrosive effects on its structure. Chemoautotrophic nitrifying bacteria utilize the residues of halites (carbamide) which migrate in the city sewer collectors, due to the damaged dampproofing of the roadway and produce nitrogen salts. Chemoorganotrophic bacteria utilize the traces of organic substrates and produce a number of organic acids (formic, acetic, propionic, citric, oxalic and other). The activity of microorganisms so enables the origination of primary and secondary salts which affect physical properties of concretes in city sewer collectors unfavourably.

  19. Low-Energy City Policy Handbook. Part A: The city of the future, the future of the city; Part B: Lost in (energy) transition? Methods and tools

    International Nuclear Information System (INIS)

    2014-01-01

    Energy Cities started the IMAGINE initiative in 2006 to bring together cities and various stakeholders involved in urban energy issues. IMAGINE focuses on long-term perspectives and visioning approaches to energy and territory. Although an increasing number of cities are committing to achieving the EU objectives, notably through the Covenant of Mayors, they are also facing several obstacles. One of them is the difficulty for cities, their citizens and stakeholders to imagine, evaluate and accept the changes that are needed. Helping cities overcome such obstacles is the objective of the IMAGINE initiative. It is a platform for foresight, collaboration and exchanges, leading to action and change. Between 2012 and 2014, IMAGINE benefited from the support of the INTERREG IV program through a project called 'IMAGINE... low energy cities'. This project gathered 10 partners: Energy Cities - coordinator, Hafen City University - academic partner, and 8 pilot cities: Bistrita (Romania), Dobrich (Bulgaria), Figueres (Spain), Lille (France), Milton Keynes (United Kingdom), Modena (Italy), Munich (Germany), Odense (Denmark). These local authorities have committed to involving local stakeholders in co-building their cities' Local Energy Road-maps 2050 thanks to participatory approaches. Final publication from the 'IMAGINE low energy cities' project, this handbook is aimed at decision makers in European local authorities searching for new ways to work towards achieving low energy cities. It is intended to give inspiration and practical advice to elected political leaders as well as civil servants to run their own energy transition process at the local level. There are two ways to read this handbook. In Part A, it explains the way local authorities organise themselves to start and run a political and organisational process to set sustainable energy policies. This part of the handbook presents the results of the development of Local Energy Road-maps 2050 in the eight IMAGINE pilot

    Performed in 2013, sampling of centralized and noncentralized water-supply and analysis of engineering technology materials on household water use in 6 cities of Murmansk region (Nikel, Zapolyarny, Olenegorsk, Montchegorsk, Apatity, Kirovsk), subjected to industrial emissions, enabled to evaluate and compare levels of 15 metals in water sources (lakes and springs) and the cities' drinkable waters. Findings are that some cities lack sanitary protection zones for water sources, most cities require preliminary water processing, water desinfection involves only chlorination. Concentrations of most metals in water samples from all the cities at the points of water intake, water preparation and water supply are within the hygienic norms. But values significantly (2-5 times) exceeding MACs (both in water sources and in drinkable waters of the cities) were seen for aluminium in Kirovsk city and for nickel in Zapolarny and Nikel cities. To decrease effects of aluminium, nickel and their compounds in the three cities' residents (and preserve health of the population and offsprings), the authors necessitate specification and adaptation of measures to purify the drinkable waters from the pollutants. In all the cities studied, significantly increased concentrations of iron and other metals were seen during water transportation from the source to the city supply--that necessitates replacement of depreciated water supply systems by modern ones. Water taken from Petchenga region springs demonstrated relatively low levels of metals, except from strontium and barium.

    Full Text Available The term “eco-city,” and similar concepts such as “green” and “sustainable” cities, has evolved overtime concurrent to the development of the understanding of social change and mankind’s impact on environmental and economic health. With the advent of climate change impacts, modern economies developed the green city policy to create sustainable urban development, low emission, and environmentally friendly cities. In South Africa municipalities, including Buffalo City Metropolitan Municipality (BCMM have been tasked to and implement the green city policy. However, BCMM is yet to develop the green city policy that clearly articulate how the municipality will combat climate change and reduce its Green House Gases (GHG emissions in its spatial planning designs. Against this background, this article reviews and analyses green policy landscape in Metropolitan Municipalities. It is envisaged that the research will provide the basis for the development of a comprehensive green policy strategies and programmes for the local transition to action in Buffalo City Metropolitan Municipality, in the Eastern Cape Province.

    This paper investigates how the historical and cultural heritage of cities is and can be underpinned by means of smart city tools, solutions and applications. Smart cities stand for a conceptual technology-and-innovation driven urban development model. By becoming `smart', cities seek to achieve prosperity, effectiveness and competitiveness on multiple socio-economic levels. Although cultural heritage is one of the many issues addressed by existing smart city strategies, and despite the documented bilateral benefits, our research about the positioning of urban cultural heritage within three smart city strategies (Barcelona, Amsterdam, and London) reveals fragmented approaches. Our findings suggest that the objective of cultural heritage promotion is not substantially addressed in the investigated smart city strategies. Nevertheless, we observe that cultural heritage management can be incorporated in several different strategic areas of the smart city, reflecting different lines of thinking and serving an array of goals, depending on the case. We conclude that although potential applications and approaches abound, cultural heritage currently stands for a mostly unexploited asset, presenting multiple integration opportunities within smart city contexts. We prompt for further research into bridging the two disciplines and exploiting a variety of use cases with the purpose of enriching the current knowledge base at the intersection of cultural heritage and smart cities.

    Full Text Available The realization of e-city is a necessary component for achieving the green city. This paper outlines a vision for an e-city platform that is based on knowledge brokerage in the green city. The proposed platform will be a venue for creating dynamic virtual organizations to harness collective intelligence of knowledge hubs to analyze and manage sustainability knowledge in urban areas. Knowledge assets of participating organizations will be presented in three dimensions: process structures, human profile and software systems. These three facets of knowledge will be accessible and viewable through a self-describing mechanism. Cities can post their geospatial and real-time data on the net. Relevant environmental and energy-use data will be extracted using topic maps and data extraction services. Local decision makers can synchronize work processes (from participating hubs to create an integrated workflow for a new ad hoc virtual organization to collaboratively analyze the multifaceted nature of sustainable decision making. An e-city platform is envisioned in this paper that will be realized through intelligent, agent-like, domain-specific middleware (KnowWare. Through triangulation between people, software and processes, these KnowWare will discover, negotiate, integrate, reason and communicate knowledge (related to energy and environment from across organizations to the right person at the right time. KnowWare is fundamentally, a portal of social semantic services that resides on a cloud computing infrastructure. Knowware exploits thee main tools: 1 existing ontologies to represent knowledge in a semantic manner, 2 topic maps to profile sources of knowledge and match these to the complex needs of sustainability analysis, 3 domain-specific middleware for knowledge integration and reasoning.

    Full Text Available The paper is related to both theoretical concepts and best practice in the field of Knowledge Management Strategy. We have designed a mixture of research methodology that covers literature review, comparative case-study analysis, and best practices in the Smart-City field, in order to propose an adequate model, with a suitable quick guide for implementation that may provide a solution for the development of Cluj-Napoca case study. After an in-depth literature review, we proposed the following as the main research question: Could a smart city comparative case study methodology be used as a knowledge management strategy for development? After a preparatory stage we focused on the upgrading of a smart city development model. To put this model at work we looked for and designed a quick guide that can be used as a tool for implementing the model named Knowledge Broker Intervention Model (KBIM. This KBIM and the quick guide for implementation may be seen as our small contribution to the theory and practice in the field. The Knowledge Broker Intervention Model was designed to improve the networks of components in a new way and a more sustainable development. These outcomes of the comparative analysis may be used as a starting point for the transformation of Cluj Napoca into a Smart City based on the quick guide we developed. Cluj Innovation City is a first step towards transforming Cluj-Napoca into a Smart City, which could be developed around the existing Cluj IT Cluster. The role of a knowledge broker would be to ensure that knowledge of the organizational culture of private firms could be harvested, processed and further transferred to universities. In their turn, universities would adopt the new knowledge and apply it in such a way in which it will influence the nurture of scientists. This would come as a solution in the process of closing the gap between knowledge generation, dissemination and feedback actions. It will link research results with

    2013-01-01

    With “soft” costs accounting for well over 50% of the installed price of residential photovoltaic (PV) systems in the United States, this study evaluates the effect of city-level permitting processes on the installed price of residential PV systems and on the time required to develop those systems. The study uses a unique dataset from the U.S. Department of Energy's Rooftop Solar Challenge Program, which includes city-level permitting process “scores,” plus data from the California Solar Initiative and the U.S. Census. Econometric methods are used to quantify the price and development-time effects of city-level permitting processes on more than 3000 PV installations across 44 California cities in 2011. Results suggest that cities with the most favorable permitting practices can reduce average residential PV prices by $0.27–$0.77/W (4–12% of median PV prices in California) compared with cities with the most onerous permitting practices, depending on the regression model used. Though the empirical models for development times are less robust, results suggest that the most streamlined permitting practices may shorten development times by around 24 days on average (25% of the median development time). These findings illustrate the potential price and development-time benefits of streamlining local permitting procedures for PV systems. - Highlights: • The study uses a unique dataset from the U.S. DOE's Rooftop Solar Challenge Program. • We quantify the price and development-time effects of city-level permitting processes. • Most favorable permitting practices can reduce average residential PV prices by $0.27–$0.77/W

    Full Text Available In the quest for achieving sustainable cities, Intelligent and Knowledge City Programmes (ICPs and KCPs represent cost-efficient strategies for improving the overall performance of urban systems. However, even though nobody argues on the desirability of making cities “smarter”, the fundamental questions of how and to what extent can ICPs and KCPs contribute to the achievement of urban sustainability lack a precise answer. In the attempt of providing a structured answer to these interrogatives, this paper presents a methodology developed for investigating the modalities through which ICPs and KCPs contribute to the achievement or urban sustainability. Results suggest that ICPs and KCPs efficacy lies in supporting cities achieve a sustainable urban metabolism through optimization, innovation and behavior changes.

    1999-01-01

    This book starts out with the optimistic perspective that modern cities can indeed play a strategic role in the necessary pathway to sustainable development, with particular emphasis on the opportunities offered by local energy and environmental initiatives. Our study aims to demonstrate that an urban sustainability policy has many socio-economic benefits, while it also seeks to identify the critical success and failure factors of sustainable city innovations. After a comprehensive review of various opportunities and experiences, attention is focused particularly on renewable energy resources which may offer new potential for the active involvement of local authorities. The study also highlights major impediments regarding the adoption and implementation of renewable energies, in particular, the development of advanced energy-environmental technology in a world dominated by natural (public) monopolies and/or monopolistic competition elements. In this context both theoretical and empirical elements are discussed, as well as institutional aspects. The theory and methodology is tested by a thorough empirical investigation into local renewable energy initiatives in three European countries, viz. Greece, Italy and The Netherlands. Based on an extensive data base, various statistical models are estimated in order to identify the key elements and major driving forces of sustainable development at the city level. And finally, the study is concluded with a long list of applicable and operational policy guidelines for urban sustainability. These lessons are largely based on meta-analytic comparative studies of the various initiatives investigated. (orig.)

    2018-01-01

    In this paper, we assess the challenges of water, waste and climate change in six cities across the U.S.: New York City, Boston, Milwaukee, Phoenix, Portland and Los Angeles. We apply the City Blueprint ® Approach which consists of three indicator assessments: (1) the Trends and Pressures Framework (TPF), (2) the City Blueprint Framework (CBF) and (3) the water Governance Capacity Framework (GCF). The TPF summarizes the main social, environmental and financial pressures that may impede water management. The CBF provides an integrated overview of the management performances within the urban watercycle. Finally, the GCF provides a framework to identify key barriers and opportunities to develop governance capacity. The GCF has only been applied in NYC. Results show that all cities face pressures from heat risk. The management performances regarding resource efficiency and resource recovery from wastewater and solid waste show considerable room for improvement. Moreover, stormwater separation, infrastructure maintenance and green space require improvement in order to achieve a resilient urban watercycle. Finally, in New York City, the GCF results show that learning through smart monitoring, evaluation and cross-stakeholder learning is a limiting condition that needs to be addressed. We conclude that the City Blueprint Approach has large potential to assist cities in their strategic planning and exchange of knowledge, experiences and lessons. Because the methodology is well-structured, easy to understand, and concise, it may bridge the gap between science, policy and practice. It could therefore enable other cities to address their challenges of water, waste and climate change.

  5. City model enrichment

    Science.gov (United States)

    Smart, Philip D.; Quinn, Jonathan A.; Jones, Christopher B.

    The combination of mobile communication technology with location and orientation aware digital cameras has introduced increasing interest in the exploitation of 3D city models for applications such as augmented reality and automated image captioning. The effectiveness of such applications is, at present, severely limited by the often poor quality of semantic annotation of the 3D models. In this paper, we show how freely available sources of georeferenced Web 2.0 information can be used for automated enrichment of 3D city models. Point referenced names of prominent buildings and landmarks mined from Wikipedia articles and from the OpenStreetMaps digital map and Geonames gazetteer have been matched to the 2D ground plan geometry of a 3D city model. In order to address the ambiguities that arise in the associations between these sources and the city model, we present procedures to merge potentially related buildings and implement fuzzy matching between reference points and building polygons. An experimental evaluation demonstrates the effectiveness of the presented methods.

    Full Text Available To create a safe city free from natural disasters has been one of the important criteria in city planning. Since large cities have suffered from large fires caused by earthquakes, the planning of open spaces to prevent the spread of fires is part of the basic structure of city planning in Japan. Even in the feudal city of Edo, the former name of Tokyo, there had been open spaces to prevent fire disasters along canals and rivers. This paper discusses the historical evolution of open space planning, that we call landscape planning, through the experiences in Tokyo, and clarifies the characteristics and problems for achieving a safe city.

    Full Text Available The peripheral and semi-peripheral roles of islands are being challenged and contested as contemporary island cities assume positions as engines of growth and become centres of progress for driving economic development. Notably, island cities around the globe have become instrumental in shaping and influencing the dynamics of urban development as cities now compete with each other to strategically position themselves in today’s competitive global economy that leverages creativity and innovation. Particularly in a creative economy, the availability, quantity, and quality of unique cultures; creative talents; and creative/cultural industries within a city are differentiating and determining factors that can boost a city’s position and subsequently spur economic growth and progress. Against this backdrop, this paper explores the position of the island city of George Town (Penang en route to becoming a Creative City. This paper highlights the island’s urban dynamics as well as discusses the promise and perils of transforming George Town into a Creative City in its own right.

    Full Text Available Comparing adaptations to noisy city environments with those to natural mountain environments on the community level can provide significant insights that allow an understanding of the impact of anthropogenic noise on invertebrates that employ loud calling songs for mate attraction, especially when each species has its distinct song, as in the case of cicadas. In this study, we investigated the partitioning strategy of cicada assemblages in city and mountain environments by comparing the acoustic features and calling activity patterns of each species, recorded using automated digital recording systems. Our comparison of activity patterns of seasonal and diel calling revealed that there was no significant temporal partitioning of cicada assemblages in either environment. In addition, there was no correlation between the acoustic distance based on spectral features and temporal segregation. Heterospecific spectral overlap was low in both city and mountain environments, although city and mountain cicada assemblages were subject to significantly different levels of anthropogenic or interspecific noise. Furthermore, for the common species found in both environments, the calling activity patterns at both seasonal and diel time scales were significantly consistent across sites and across environments. We suggest that the temporal calling activity is constrained by endogenous factors for each species and is less flexible in response to external factors, such as anthropogenic noise. As a result, cicada assemblages in city environments with low species diversity do not demonstrate a more significant temporal partitioning than those in mountain environments with high species diversity.

    The paper developed an analysis method of the energy supply/demand structure of city and compared the conventional city and a city considering energy conservation. An energy supply/demand flow chart was newly proposed. From this flow chart, `energy sustainability ratios` was proposed as a new index for comprehensively evaluating two elements of the energy conservation by load reduction and heightening of energy conversion rates and the utilization of waste heat and renewable energy. A method for analysis of the energy supply/demand structure of city was developed including daily supply/demand patterns in the area where individual equipment in every residence/building correspond to the energy supply and the area where centralized energy systems such as district energy supply correspond it. From the developed analysis method, analysis was made of a newly developed city with a 0.6 million population in terms of the conventional city and energy conservation city, to clarify the present energy supply/demand structure of city and to express it in an energy flow chart. At the same time, validity of the analysis method and evaluation indexes were confirmed by comparing the conventional city and energy conservation city. 15 refs, 27 figs., 17 tabs.

    Reliable modeling for thermal infrared (IR) signatures of real-world city scenes is required for signature management of civil and military platforms. Traditional modeling methods generally assume that scene objects are individual entities during the physical processes occurring in infrared range. However, in reality, the physical scene involves convective and conductive interactions between objects as well as the radiations interactions between objects. A method based on radiosity model describes these complex effects. It has been developed to enable an accurate simulation for the radiance distribution of the city scenes. Firstly, the physical processes affecting the IR characteristic of city scenes were described. Secondly, heat balance equations were formed on the basis of combining the atmospheric conditions, shadow maps and the geometry of scene. Finally, finite difference method was used to calculate the kinetic temperature of object surface. A radiosity model was introduced to describe the scattering effect of radiation between surface elements in the scene. By the synthesis of objects radiance distribution in infrared range, we could obtain the IR characteristic of scene. Real infrared images and model predictions were shown and compared. The results demonstrate that this method can realistically simulate the IR characteristic of city scenes. It effectively displays the infrared shadow effects and the radiation interactions between objects in city scenes.

    The highest movement in Semarang City is dominated by motorcycles, which reached 79% of the number of vehicles. Highest percentage movement use motorcycle caused the highest percentage accident by motorcycle users, which reached 66% and 9% involving high school students. This happens because of the dependence of motorcycles usage in fulfilling the needs of movement in the city of Semarang. Understanding student travel behavior based on their activities is used to know travel needs and the cause of dependence on motorcycle usage. Analysis method in this study use network analysis to compare the potential accessibility and actual accessibility to known why motorcycle chosen by students as the main mode. In addition, phenomenology analysis is used to explain the intent and reasons the data produced by network analysis. The analysis result indicates that the high use of motorcycles by high school students in the Semarang city due to the absence of other effective and efficient modes in fulfilling the movement needs. Even, the student which can potentially use public transport preferred to use a motorcycle. This mode is more effective and efficient because of its flexibility and lower costs.

    Lucknow metropolitan city is one of the most populated cities of India, which have been facing many problems such as chaotic urbanization, overpopulation, water scarcity, waterlogging, etc., among these water scarcity is one of the important problem. Rain water harvesting is a futuristic tool for mitigation of water scarcity problem through conservation and storage of rain water. This rain water can be used for all purposes by human beings, thus it is necessary to check the chemistry of rain water. The rain water samples were collected from the five zones of Lucknow city. For the comparative study, water samples have been collected from two different dates first from first rainfall and second after 3 days of interval in the second rainfall. The heavy metal concentrations were found in both first and second rainfall water samples in all zones of Lucknow city. The concentration of chromium, cadmium and lead were found to be sufficiently high in several samples. These heavy metals show the concentration above the permissible limit as set by WHO, which can cause various adverse health impacts.

    Rezende, Vera F

    2010-01-01

    This article analyses the connections between the ideas and principles of American city planning from 1920 with those articulated by Brazilian city planners in the 1930s and implemented by the administration of the City of Rio de Janeiro, then the capital of Brazil, notably during the period of the Estado Novo [The New State] from 1937 to 1945. In a period characterized by the centralization of political power and the concentration of decision-making in the hands of the president and the state, the City of Rio de Janeiro undertook a series of restructuring projects which utilized new forms of administration and organization. This article explores the links between urban planning in Brazil and the USA that were a notable feature of these projects. It examines particular requirements set down in city plans, city planning commissions and funding for urban activities, such as 'excess condemnation', by focusing upon articles and books written by four Brazilian engineers and proposals put forward by the American City Planning Institute, detailed in the proceedings of the National Conference on City Planning, in the periodical, City Planning and works by affiliated authors.

    2018-01-01

    The recent emergence of smart cities is highly supported by the development of IT and IoT technologies. Nevertheless, a smart city needs to be built to meet the needs and requirements of its citizens. In order to build a smart city it is necessary to understand the benefits of such a city. A smart city is, beyond technology, populated by people. A smart city can be raised by its citizens’ contribution, and gamification is the means to motivate them. In this paper we included gamification techniques in the stage of capturing the citizens’ requirements for building a smart city. The system proposed in the paper is to create an application that allows the building of a virtual smart city customized by each user. From this virtual city, the most relevant features are extracted.

    Full Text Available The paradigm of network society emphasizes a distinct pattern comparing to the previous information society, as a "result of ongoing innovations embedding social networks". The question of how technological improvements (intelligent design, the use of intelligent devices, and a larger distribution of knowledge among diverse layers and dimensions of social networks have transformed mental softs, cultural practices, and socio-economic and political organizations, through the development of the network form,- networked individuals, communities, stakeholders, cities, regions, states, "interconnected life"- gives different responses depending on the positioning of the researcher inside/outside a specific field of studies, or knowledge network, and on the attitude adopted towards technology as a "civilization shifter". The conceptualization of the „smart city project” extends dilemmas and controversy and requires new understandings of how critical-reflexive and programmed regimes of knowledge, intermingle the knowledge creation and the distribution inside/outside the city. The current paper draws a line of flight between human, institutional and technological dimensions of the smart city.

    In 1995, the City of North Bonneville, WA installed a 10-ton Ground Source Heat Pump (GSHP) to replace the electric resistance furnace in its 4,000 square, foot City Hall. North Bonneville is 30 miles east of Portland, Oregon, at river level in the Columbia River Gorge. Funded jointly by the Bonneville Power Administration, the State of Washington and the City, this project has successfully reduced the heating cost of City Hall by nearly one-half while dramatically increasing comfort. It has become a commercial model in the Pacific Northwest for assessing values of commercial GSHP retrofits. This interim report compares estimated savings with actual experience for the first operating year. Projected savings were $1,500; actual savings were $1,390 prior to adjustment for extreme weather. Adjusted savings for Heating Year 1996 were $1,490, a 47 percent decrease. Maintenance savings (not itemized) were in addition to this amount. Monitoring continues in 1997.

    Concentrations of Cr, Co, Ni, Cu, Zn, Pb and Fe in the top-soils (0-10 cm) of Havana city urbanized and un-urbanized areas were measured by X-ray fluorescence analysis. The mean Cr, Co, Ni, Cu, Zn and Pb contents in the urban topsoil samples from Havana City (151 ± 90, 13.9 ± 4.1, 66 ± 26, 101 ± 51, 240 ± 132 and 101 ± 61 mg.kg -1 , respectively) were compared with mean concentrations for other cities around the world. The results revealed higher concentrations of heavy metals in topsoil samples from industrial sites. Lowest heavy metal contents were determined in the un-urbanized areas. The comparison with Dutch soil quality guidelines showed a slightly contamination with Cr, Co, Ni Cu and Zn in all studied sites and with Pb in industrial soils. On the other hand, the metal-to-iron normalisation using Earth crust contents as background showed that soils from urbanized areas in Havana city (industrial sites, parks and school grounds) are moderately enriched by zinc, moderately to severe enriched (city parks and school grounds) and severe enriched (industrial sites) by lead.

    The capacity of adaptation is essential elements towards urban resilience. One adaptation that can be done is to consider the provision of open space and public space in the city. Yogyakarta City development which focused on the built area and negates the open space has blurred the characteristics of the city. Efforts in increasing the availability of public space is one of the seven priorities of the programs included in the environmental and the utilization of space in Yogyakarta City. An understanding of the provision of public green open spaces in Yogyakarta is important because the products and processes that take place in a development will determine the successful implementation of the development plan. The objectives of this study are as follows: (1) to identify the provision green space in Yogyakarta City from the aspects of product and procedure; and (2) to identify the role of green space to build resilient city. This study is used descriptive qualitative approach with in-depth interview, literature review, and triangulation as the method for data collection. Yogyakarta has had instruments for public green open spaces provision called Masterplan Ruang Terbuka Hijau (RTH) Up-Scaling Yogyakarta 2013-2032 which govern the typologies and criteria for green open space development in the city.Public green open spaces development mechanism can be grouped into the planning phase, the utilization phase, and the control phase of each consisting of legal and regulatory aspects, institutional aspects, financial aspects, and technical aspects. The mechanism of green open space provision should regard the need of advocacy for “urban green commons” (UGCs) development as a systematic approach of collective-participatory for urban land management.

    Full Text Available Formulation of the problem. Today in Ukraine, we can observe the process of recovery of historical memory at all levels – national, local, personal. Unfortunately, not every resident of our city knows the history of his native land, although it is known that people who do not know their own history, cannot understand the present and build the future. This statement is particularly relevant for today's youth, living in the era of change, to understand which it is necessary to look into the past of their country and city. Analysis of the research. Among the various studies that reveal in detail the early history of the city on the Dnieper River, an important place belongs to works by D. Yavornytsky, S. Revsky, G. Gulyaev, V. Starostin, M. Kavun and others. The purpose of the article is making a comparative analysis of the causes and consequences of two construction projects of Katerynoslav on the Kilchen’ and on the Dnipro. Conclusion. The early history of our city demonstrates that Russian colonization power understood the strategic importance of its location, as there were here from the sixteenth century Ukrainian settlements such as Samar, Old Kodak, New Kodak and more. The Russian concept of building “the third imperial capital" was defeated, as it was being held only on the personal enthusiasm of Catherine II and her favorite Potemkin, but the real development of the city as an industrial center of Dnieper region began only in the late nineteenth century. Rich historical and cultural heritage on the territory of modern city creates excellent conditions for the development of diverse tourism industry, which can direct metropolis life in a new direction.

    Background It is anecdotally recognized that commercial gym users assume supplements in order to improve performance or health. However, dietary behaviours of people and athletes attending commercial gyms have been poorly studied. The exact amount and frequency of dietary supplements consumption are still needed to be investigated. The main purpose of this study is to understand the quantity and quality of food intake, as well as dietary supplementation in people attending commercial gyms. Secondly to compare the city centre and the suburbs of Palermo, Italy. Methods A face-to-face questionnaire was administered to 561 subjects, 207 from the city centre (CC) and 354 from the suburbs (SB) of Palermo, Italy. Frequency of protein supplements use and association with dietary behaviours were investigated. Subsequently, the frequency distribution was used for demographic assessment. Results Frequency of protein consumption was similar in both groups (30% for CC and 28.8% for SB). Males show greater consumption percentages than females (30.5% in males and 6.9% in females). Milk and chicken are the most frequently consumed foods. Data show that non-supplement users (NSU) consume significantly more snacks and bakery products than supplement users (SU) (P gym users is 30% for the CC and 28.8% for the SB. Significant differences were found between CC and SB females, underlining an interesting discrepancy, indicating to dietary supplement industries regarding regional implications. Subjects that use protein supplements also consume larger quantities of high protein food compared to NSU. NSU also eat higher proportions of unhealthy food compared to SU. PMID:24976800

    Full Text Available In this article we made a research about the Sentient Cities and produced an assessment model to analyse if a city is or could be potentially considered one. It can be used to evaluate the current situation of a city before introducing urban policies based on citizen participation in hybrid environments (physical and digital. To that effect, we've developed evaluation grids with the main elements that form a Sentient City and their measurement values. The Sentient City is a variation of the Smart City, also based on technology progress and innovation, but where the citizens are the principal agent. In this model, governments aim to have a participatory and sustainable system for achieving the Knowledge Society and Collective Intelligence development, as well as the city’s efficiency. Also, they increase communication channels between the Administration and citizens. In this new context, citizens are empowered because they have the opportunity to create a Local Identity and transform their surroundings through open and horizontal initiatives.

    Directory of Open Access Journals (Sweden)

    Koichiro Mori

    2015-09-01

    Full Text Available We have developed a visualized 3-D model of a City Sustainability Index (CSI based on our original concept of city sustainability in which a sustainable city is defined as one that maximizes socio-economic benefits while meeting constraint conditions of the environment and socio-economic equity on a permanent basis. The CSI is based on constraint and maximization indicators. Constraint indicators assess whether a city meets the necessary minimum conditions for city sustainability. Maximization indicators measure the benefits that a city generates in socio-economic aspects. When used in the policy-making process, the choice of constraint indicators should be implemented using a top-down approach. In contrast, a bottom-up approach is more suitable for defining maximization indicators because this technique involves multiple stakeholders (in a transdisciplinary approach. Using different materials of various colors, shapes, sizes, we designed and constructed the visualized physical model of the CSI to help people evaluate and compare the performance of different cities in terms of sustainability. The visualized model of the CSI can convey complicated information in a simple and straightforward manner to diverse stakeholders so that the sustainability analysis can be understood intuitively by ordinary citizens as well as experts. Thus, the CSI model helps stakeholders to develop critical thinking about city sustainability and enables policymakers to make informed decisions for sustainability through a transdisciplinary approach.

  17. Summer ammonia measurements in a densely populated Mediterranean city

    Full Text Available Real-time measurements of ambient concentrations of gas-phase ammonia (NH3 were performed in Barcelona (NE Spain in summer between May and September 2011. Two measurement sites were selected: one in an urban background traffic-influenced area (UB and the other in the historical city centre (CC. Levels of NH3 were higher at CC (5.6 ± 2.1 μg m−3 or 7.5 ± 2.8 ppbv compared with UB (2.2 ± 1.0 μg m−3 or 2.9 ± 1.3 ppbv. This difference is attributed to the contribution from non-traffic sources such as waste containers, sewage systems, humans and open markets more dense in the densely populated historical city centre. Under high temperatures in summer these sources had the potential to increase the ambient levels of NH3 well above the urban-background-traffic-influenced UB measurement station. Measurements were used to assess major local emissions, sinks and diurnal evolution of NH3. The measured levels of NH3, especially high in the old city, may contribute to the high mean annual concentrations of secondary sulfate and nitrate measured in Barcelona compared with other cities in Spain affected by high traffic intensity. Ancillary measurements, including PM10, PM2.5, PM1 levels (Particulate Matter with aerodynamic diameter smaller than 10 μm, 2.5 μm, and 1 μm, gases and black carbon concentrations and meteorological data, were performed during the measurement campaign. The analysis of specific periods (3 special cases during the campaign revealed that road traffic was a significant source of NH3. However, its effect was more evident at UB compared with CC where it was masked given the high levels of NH3 from non-traffic sources measured in the old city.

    Full Text Available In the wide and complex panorama of urban transformation, waterfront revitalisation is one of the most interesting phenomena of urban renewal of the last decades, bringing ‘cities on water’ around the world to a new leadership. After years of oblivion, the presence of the natural element –water– have shown to be of great appeal as an attractive pole for the quality of every day’s life. In particular, the visual contact with water together with pedestrian paths along the waterfronts and the implementation of waterborne transports, where possible, are giving an added value to these areas, becoming even more interesting in terms of Real Estate. Now spread out and developed at a global dimensions, involving both, big cities but also medium and smallscale cities at all latitudes and in all continents, waterfront regeneration is in many cases the starting point for the regeneration of the city itself and of its relocation in the international context. Under this point of view, marine, port and fluvial cities can be considered laboratories for the process of urban renewal in terms of residential, transports, public spaces and quality of the environment, in view of both, the broad range of cases and the quality of the results. In light of its 20-year long activity in terms of monitoring and studying best practices in the field of waterfront revitalisation, the Centre Cities on Water carried-out an international overview, developing a comparative analysis of the key element for the success of these operation. To this regards, a selection of case-studies has been identified at international level, according to the main ‘ingredients’ for a sustainable cohabitation between ports and cities and for a lasting success in waterfront regeneration processes. Water quality, public and free access and to water, public spaces, gradual and flexible development and shared participation in the entire process as well as a mix of functions and uses and the

    There are differences in the concepts of smart cities, which are reflected in many ideas and solutions. Globally one of the similarities of the goals for achieving smart cities is sustainable developmentwith the provision of best living conditions for people beingthe first priority. Ho Chi Minh City is not out of trend, taking the planning steps for the goal of becoming a smart city. It is necessary that design and construction of high-rise dwelling houses meet the criteria of "smart city" concept. This paper explores the design of high-rise dwelling houses forHo Chi Minh City with regards tothe framework of "smart city" concept. Methods used in the paper includedata collection, analytical - synthetical and modeling method.In order to proposedesign tasks and solutions of high-rise dwelling houses forHo Chi Minh Cityinthe concept "smart city"in the current period and near future, we present new approach, whichcan alsobe applied in practice for different cities in Vietnam.Moveover, it can also establishinformation resources, which areuseful in connecting and promotingfurther development for the success of a "smart city" program.

    2016-01-01

    Heat response plans are becoming increasingly more common as US cities prepare for heat waves and other effects of climate change. Standard elements of heat response plans exist, but plans vary depending on geographic location and distribution of vulnerable populations. Because heat events vary over time and affect populations differently based on vulnerability, it is difficult to compare heat response plans and evaluate responses to heat events. This article provides an overview of the Baltimore City heat response plan, the Code Red program, and discusses the city's response to the 2012 Ohio Valley/Mid Atlantic Derecho, a complex heat event. Challenges with and strategies for evaluating the program are reviewed and shared.

    2017-12-31

    This article analyses whether existing LCA and sustainability methods can be used in the assessment of a city or an urban region. The approach is performed through the review of current existing LCA-based and sustainability standards and guidelines. A focus is put into those LCA-based standards specially designed for the built environment. Moreover, a review of non-LCA based standards, indices and guides for the assessment of the sustainability of countries, cities or urban regions is done. The purpose is to check if these assessment tools can provide good results in the absence of LCA-based assessments for cities and urban regions. This review demonstrates the lack of consensus in the definition of both, the city and its boundaries, which hinders the development of useful sustainability standards. Furthermore, it is concluded that current sustainability assessment tools miss, at least, one of these aspects: (i) holistic point of view, (ii) focus on various environmental impacts, (iii) a Life Cycle (LC) perspective, and (iv) the possibility to compare the results among different cities or urban regions. From the LCA perspective, the deficiencies found also include the need for a definition of the function, functional unit (FU), and reference flow (RF) of neighbourhoods, cities, and urban regions.

    Manea, L.; Manea, A.; Florea, D.; Tarulescu, S.

    2017-10-01

    In the present paper was studied the noise pollution in Cernavodă city. The noise measurements were made for nine intersections from different city areas. Noise measurements were taken for three chosen routes with high population density, heavy traffic, commercial and residential buildings. Average, maximum and minimum values were collected and compared with standards. The impact of road traffic noise on the community depends on various factors such as road location and design, land use planning measures, building design, traffic composition, driver behaviour and the relief. In the study area 9 locations are identified to measure noise level. By using sound level meter noise levels are measured at different peak sessions i.e. morning, afternoon and evening. The presented values were collected for evening rush hour.

    2013-01-01

    Little is known about the intensity and extension of subsurface urban heat islands (UHI), and the individual role of the driving factors has not been revealed either. In this study, we compare groundwater temperatures in shallow aquifers beneath six German cities of different size (Berlin, Munich, Cologne, Frankfurt, Karlsruhe and Darmstadt). It is revealed that hotspots of up to +20K often exist, which stem from very local heat sources, such as insufficiently insulated power plants, landfills or open geothermal systems. When visualizing the regional conditions in isotherm maps, mostly a concentric picture is found with the highest temperatures in the city centers. This reflects the long-term accumulation of thermal energy over several centuries and the interplay of various factors, particularly in heat loss from basements, elevated ground surface temperatures (GST) and subsurface infrastructure. As a primary indicator to quantify and compare large-scale UHI intensity the 10-90%-quantile range UHII(10-90) of the temperature distribution is introduced. The latter reveals, in comparison to annual atmospheric UHI intensities, an even more pronounced heating of the shallow subsurface. Copyright © 2012 Elsevier B.V. All rights reserved.

  10. An Appraisal of Asia-Pacific Cities as Control and Command Centres Embedded in World City Network

    2017-08-01

    Full Text Available Since the globalization trend is proliferating at a staggering rate, world cities have emerged as the most dominant vanguard incorporated into global economy. Control and command function is one of the robust integral parts of world city formation, which is closely associated with the corporate headquarter status of some dominant multinational companies. Previous research works on this topic tend to concentrate on the Western Europe and North American arenas neglecting the Asia-Pacific region. Hence, the objective of this paper is to explore control and command functions of Asia-Pacific cities with reference to headquarters’ locations of multinational companies. The methodology will utilize the Forbes global 2000 dataset from the seminal study of GaWC research group, and apply the control and command center model and the interlocking city network model to discover the control and command index, as well as network connectivity of Asia-Pacific cities. Based upon the empirical study of this research, we could identify the hierarchical structure and spatial structure of Asia-Pacific world cities to emerge as some control and command centers embedded in world city network.

    activities, are naturally energy efficient. The lesson taught by Jane Jacobs in her seminal book Death and Life of Great American Cities remains relevant also assuming the energy approach. More recently, emerging planning themes are including the containment and retrofitting of urban sprawl by integrating transport and land use planning. Applying Transit Oriented Development (Tod principles can induce a change in mobility choices of inhabitants of this unsustainable form of urban settlement, by giving them more mobility opportunities.Land use planning will also play a relevant role in accommodating new forms of distributed sustainable energy production in the urban fabric. The recent 2015 Snapshot of Global Photovoltaic Markets, by the International Energy Agency, confirms that economic incentives, like feed-in tariffs, are not enough to guarantee a stable diffusion of this type of energy production. After the phasing out of this incentives there diffusion of PV, reduces considerably. This is case of Italy that installed only 300 MW of PV systems in 2014, compared to 9,3 GW in 2011, 3,6 GW in 2012 and 1,6 GW in 2013. Integrating energy production in the city as part of urban design will increase the opportunity of making sustainable energy production an inherent feature of the city design, including energy production devices in the city realm and using them for retrofitting poor quality buildings.In addition, planning tools have to incorporate incentives aimed at favouring higher energy standards, both for new and existing buildings. The costs of these actions should be covered by planning normative tools. Several techniques, like the Carbon Offset Fund in Great Britain, have been tested but there is a great need of new research in this field, at national and local level, since these tools are not easy to implement without taking into account site-specific norms and approaches. In addition, the exclusive use of the market leverage risks to confine these tools to wealthy

  12. Cities and Climate - What Visions?

    International Nuclear Information System (INIS)

    Haentjens, Jean

    2015-01-01

    Given the difficulty of achieving a global agreement to cope with the challenges of climate change or even a national resilience programme, an increasing number of initiatives are coming up from the local level for preemptively implementing policies to adapt to climate change or combat it. There are several towns and cities across the world that have taken this line (Copenhagen, Totnes, Vaexjoe, Bristol, etc.) but, as Jean Haentjens shows here, an effective response to climate change requires the development of a genuine strategic vision capable of mobilizing all the actors concerned. For the moment, the towns and cities that have managed to come up with such a vision are few and far between. After a -largely historical- review of the importance of vision in changes of urban paradigm, Jean Haentjens stresses how much twenty-first century eco-urbanism broadens the range of possible solutions to the many issues facing our towns and cities today. But, though digital innovations in fact offer new opportunities at the local level, we should nonetheless be wary of 'technological solutionism': the new technologies are tools which towns and cities can use to their advantage, but to become really 'smart' they have to develop a vision. After presenting a series of established or emerging urban models (the frugal city, the creative city, the leisure city and the eco-metropolis), along with the values and imaginative conceptions that underpin them, this article shows - without being unaware of the potential obstacles - how a town or city can produce and renew its strategic vision to reinvent itself and meet the challenges of today

    Our cities, from megalopolis to rural commune, are systems of an extraordinary technological and human complexity. Their balance is threatened by the growing population and rarefaction of resources. Massive urbanization endanges the environment, while global climate change, through natural hazards generated (climatic, hydrological and geological), threats people and goods. Connect the city, that is to say, design and spread systems able to route, between multiple actors, a very large amount of heterogeneous information natures and analyzed for various purposes, is at the heart of the hopes to make our cities more sustainable: climate-resilient, energy efficient and actresses of the energy transition, attractive to individuals and companies, health and environment friendly. If multiple players are already aware of this need, progress is slow because, beyond the only connectivity, it is the urban intelligence that will create the sustainable city, through coordinated capabilities of Perception, Decision and Action: to measure phenomena; to analyze their impact on urban sustainability in order to define strategies for improvement; to effectively act on the cause of the phenomenon. In this very active context with a strong societal impact, the Sense-City project aims to accelerate research and innovation in the field of sustainable city, particularly in the field of micro and nanosensors. The project is centered around a "mini climatic City", a unique mobile environmental chamber in Europe of 400m² that can accommodate realistic models of city main components, namely buildings, infrastructures, distribution networks or basements. This R&D test place, available in draft form from January 2015 and in finalized version in 2016, will allow to validate, in realistic conditions, innovative technologies performances for the sustainable city, especially micro- and nano-sensors, at the end of their development laboratory and upstream of industrialization.

    2014-05-01

    Reducing greenhouse gas emissions to avert potentially disastrous global climate change requires substantial redevelopment of infrastructure systems. Cities are recognized as key actors for leading such climate change mitigation efforts. We have studied the greenhouse gas inventories and underlying characteristics of 22 global cities. These cities differ in terms of their climates, income, levels of industrial activity, urban form and existing carbon intensity of electricity supply. Here we show how these differences in city characteristics lead to wide variations in the type of strategies that can be used for reducing emissions. Cities experiencing greater than ~1,500 heating degree days (below an 18 °C base), for example, will review building construction and retrofitting for cold climates. Electrification of infrastructure technologies is effective for cities where the carbon intensity of the grid is lower than ~600 tCO2e GWh-1 whereas transportation strategies will differ between low urban density (~6,000 persons km-2) cities. As nation states negotiate targets and develop policies for reducing greenhouse gas emissions, attention to the specific characteristics of their cities will broaden and improve their suite of options. Beyond carbon pricing, markets and taxation, governments may develop policies and target spending towards low-carbon urban infrastructure.

    In this paper, we combine the concepts of location, liability of foreignness (LoF), and their relation to factors that drive multinational enterprises (MNEs) towards, or away from, global cities. We argue that three interrelated characteristics of global cities - cosmopolitanism, availability...... indicate that MNEs have a stronger propensity to locate in global cities than in metropolitan or peripheral areas, and that these locational choices are affected by institutional distance and industrial characteristics. The results provide empirical support for our argument that locating in a global city...... can reduce the liability of foreignness suffered by MNEs, and that global cities play a central role in the process of globalisation....

  19. Urban heat islands in the subsurface of German cities

    Science.gov (United States)

    Menberg, K.; Blum, P.; Zhu, K.; Bayer, P.

    2012-04-01

    In the subsurface of many cities there are widespread and persistent thermal anomalies (subsurface urban heat islands) that result in a warming of urban aquifers. The reasons for this heating are manifold. Possible heat sources are basements of buildings, leakage of sewage systems, buried district heating networks, re-injection of cooling water and solar irradiation on paved surfaces. In the current study, the reported groundwater temperatures in several German cities, such as Berlin, Munich, Cologne and Karlsruhe, are compared. Available data sets are supplemented by temperature measurements and depth profiles in observation wells. Trend analyses are conducted with time series of groundwater temperatures, and three-dimensional groundwater temperature maps are provided. In all investigated cities, pronounced positive temperature anomalies are present. The distribution of groundwater temperatures appears to be spatially and temporally highly variable. Apparently, the increased heat input into the urban subsurface is controlled by very local and site-specific parameters. In the long-run, the superposition of various heat sources results in an extensive temperature increase. In many cases, the maximum temperature elevation is found close to the city centre. Regional groundwater temperature differences between the city centre and the rural background are up to 5 °C, with local hot spots of even more pronounced anomalies. Particular heat sources, like cooling water injections or case-specific underground constructions, can cause local temperatures > 20°C in the subsurface. Examination of the long-term variations in isotherm maps shows that temperatures have increased by about 1°C in the city, as well as in the rural background areas over the last decades. This increase could be reproduced with trend analysis of temperature data gathered from several groundwater wells. Comparison between groundwater and air temperatures in Karlsruhe, for example, also indicates a

    The City of Hamilton has launched an extensive energy planning exercise that examines the possibility of steep increases in oil and natural gas prices. This report examined and illustrated the issue of oil and gas price points. The report also examined and presented the city's role in an era of energy constraints, focusing on the city's transit system and its vehicle fleet. In addition, in response to City Council's direction, the report presented the aerotropolis proposal and discussed freight transport issues. Specific topics of discussion included oil and natural gas prospects; prospects for high oil and natural gas prices; impacts of fuel price increases; strategic planning objectives for energy constraints; reducing energy use by Hamilton's transport and in buildings; and land-use planning for energy constraints. Energy production opportunities involve the use of solar energy; wind energy; deep lake water cooling (DLWC); hydro-electric power; energy from waste; biogas production; district energy; and local food production. Economic and social development through preparing for energy constraints and matters raised by city council were also presented. The report also demonstrated how an energy-based strategy could be paid for and its components approved. The next steps for Hamilton were also identified. refs., tabs., figs.

    Electromagnetic radiation emitted by cell phone towers is a form of environmental pollution and is a new health hazard, especially to children and patients. The present studies were taken to estimate the microwave/RF pollution by measuring radiation power densities near schools and hospitals of Chandigarh city in India. The cell phone radiations were measured using a handheld portable power density meter TES 593 and specific absorption rates were estimated from the measured values. These values of electromagnetic radiation in the environment were compared with the levels at which biological system of humans and animals starts getting affected. The values were also compared with the international exposure limits set by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). The highest measured power density was 11.48 mW/m(2) which is 1,148% of the biological limit. The results indicated that the exposure levels in the city were below the ICNIRP limit, but much above the biological limit.

    Ecological footprint determines how much natural resources are consumed by an individual, city, region, state or all inhabitants of our planet in order to ensure their requirements and needs. It includes all activities, from food consumption, housing, transport to waste produced and allows us to compare particular activities and their impacts on the environment and natural resources. Ecological footprint is important issue for making sustainable development concept more popular using simplifications, which provide the public with basic information on situation on our planet. Today we know calculations of global (worldwide), national and local ecological footprints. During our research in cities, we were concentrated on calculation of city’s ecological footprint. The article tries to outline theoretical and assumptions and practical results of climate change consequences in cities of Bratislava and Nitra (Slovakia), to describe potential of mitigating adverse impacts of climate change and to provide information for general and professional public on theoretical assumptions in calculating ecological footprint. The intention is to present innovation of ecological footprint calculation, taking into consideration ecological stability of a city (with a specific focus on micro-climate functions of green areas). Present possibilities to reduce ecological footprint are presented.

    An intersectoral partnership for health improvement is a requirement of the WHO European Healthy Cities Network of municipalities. A review was undertaken in 59 cities based on responses to a structured questionnaire covering phase IV of the network (2003-2008). Cities usually combined formal and informal working partnerships in a pattern seen in previous phases. However, these encompassed more sectors than previously and achieved greater degrees of collaborative planning and implementation. Additional WHO technical support and networking in phase IV significantly enhanced collaboration with the urban planning sector. Critical success factors were high-level political commitment and a well-organized Healthy City office. Partnerships remain a successful component of Healthy City working. The core principles, purpose and intellectual rationale for intersectoral partnerships remain valid and fit for purpose. This applied to long-established phase III cities as well as newcomers to phase IV. The network, and in particular the WHO brand, is well regarded and encourages political and organizational engagement and is a source of support and technical expertise. A key challenge is to apply a more rigorous analytical framework and theory-informed approach to reviewing partnership and collaboration parameters.

    Full Text Available Cycling as a mode of transport is a low-cost, health-improving way to travel and offers environmental benefits for the cities that promote it. It is only recently, though, with concerns over climate change, pollution, congestion, and obesity among others, that have cities throughout the world have begun to implement policies to promote cycling. In Greece, however, the use of the bicycle is limited. In Preveza, a small touristic city in Northwestern Greece where the use of the bicycle is prominent when compared to other Greek cities, there are efforts to promote cycling. Through the aid of a structured questionnaire, the residents evaluated the suitability of the city for cycling, the existing infrastructure, appropriate education, and behavior of cyclists and drivers. More than half of the residents use bicycles as their transportation and stated that bicycles are an inexpensive way of transport in the city and had the opinion that the state should encourage bicycle use by supporting subvention in bicycle acquisition. Two-thirds of the residents evaluated the cycling facilities of their city as adequate, but unsafe for young cyclists who do not follow the rules of transport. Adult cyclists, in contrast, were more loyal to the code, but stated that drivers did not respect their presence on the roads. This research provides important information on the perceived shortcomings of cycling as a transport mode in Preveza that may be of interest to towns/cities with similar characteristics.

    This article investigates the emergence of the Copenhagen slaughterhouse, called the Meat City, during the late nineteenth century. This slaughterhouse was a product of a number of heterogeneous components: industrialization and new infrastructures were important, but hygiene and the significance...... of Danish bacon exports also played a key role. In the Meat City, this created a distinction between rising production and consumption on the one hand, and the isolation and closure of the slaughtering facility on the other. This friction mirrored an ambivalent attitude towards meat in the urban space: one...... where consumers demanded more meat than ever before, while animals were being removed from the public eye. These contradictions, it is argued, illustrate and underline the change of the city towards a ‘post-domestic’ culture. The article employs a variety of sources, but primarily the Copenhagen...

    Full Text Available A smart city is a sustainable and efficient urban centre that provides a high quality of life to its inhabitants through optimal management of its resources. Chemical industry has a key role to play in the sustainable evolution of the smart cities. Additionally, chemistry is at the heart of all modern industries, including electronics, information technology, biotechnology and nano-technology. Chemistry can make the smart cities project more sustainable, more energy efficient and more cost effective. There are six broad critical elements of any smart city: water management systems; infrastructure; transportation; energy; waste management and raw materials consumption. In all these elements chemistry and chemical engineering are deeply involved.

  17. Policy Responsiveness and Political Accountability in City Politics

    2017-03-01

    coverage of daily council business, leaves most voters inclined to rely on something other than political signals when they decide who to support. Inevitably, a candidate’s personal character and length of experience take on a larger priority in the voting decision. So, the longer a councillor serves, the longer he or she might be likely to keep serving. The natural outcome of this phenomenon is that city councils are less likely to become polarized as councillors have an incentive to seek consensus by limiting obvious policy distinctions between themselves and their fellow representatives, contributing to a dynamic where city council works more like a corporate body and less like a partisan legislature. As long as citizens remain largely unperturbed by the overall actions of their city council, they might judge the risk of replacing them at election time as unnecessarily high compared to sticking with the status quo. This behaviour challenges much of the prevailing theory about how political processes improve political responsiveness and accountability. This is occurring at a time when cities are emerging as important and increasingly powerful nodes in the modern global economy. That the very nature of how they are governed is diverging so markedly from the norm that Canadians have come to expect from other levels of government is not something to be considered lightly.

    Public quality reporting programs have been widely implemented in hospitals in an effort to improve quality and safety. One such program is Hospital Compare, Medicare's national quality reporting program for US hospitals. The New York City sanitary grade inspection program is a parallel effort for restaurants. The aims of Hospital Compare and the New York City sanitary inspection program are fundamentally similar: to address a common market failure resulting from consumers' lack of information on quality and safety. However, by displaying easily understandable information at the point of service, the New York City sanitary inspection program is better designed to encourage informed consumer decision making. We argue that this program holds important lessons for public quality reporting of US hospitals. © 2014 Society of Hospital Medicine.

    Full Text Available Essay faces the problem of determinacy of global capitalism processes for the reality of urban political life. The city is naturally communitarian form of human life and seems to be the place where radical pro-community politics could be undertaken. Already existing and operating forms of power could fruitfully influence the city social relations. Values and norms of conduct are broadly delegated on the urban space and materiality, thus conscious shaping of city space has severe consequences for community life. If a crisis of the political partly has its roots in metamorphoses of the cities, then also remedies, rising from the urban materiality and reestablishing political subjects, could be thought. City, as most real place of political life could be either reduced to the aggregate of consumers or reestablished as a political community. Due to this is the place where undesired course of action could be stopped, hence precisely here the radical democratic politics can emerge.

    2014-04-01

    Poor diet is a leading cause of disability, death, and rising health care costs. Government agencies can have a large impact on population nutrition by adopting healthy food purchasing policies. In 2007, New York City (NYC) began developing a nutrition policy for all foods purchased, served, or contracted for by City agencies. A Food Procurement Workgroup was created with representatives from all City agencies that engaged in food purchasing or service, and the NYC Health Department served as technical advisor. The NYC Standards for Meals/Snacks Purchased and Served (Standards) became a citywide policy in 2008. The first of its kind, the Standards apply to more than 3,000 programs run by 12 City agencies. This paper describes the development process and initial implementation of the Standards. With more than 260 million meals and snacks per year covered, the Standards increase demand for healthier products, model healthy eating, and may also affect clients' food choices beyond the institutional environment. Our experience suggests that implementation of nutrition standards across a wide range of diverse agencies is feasible, especially when high-level support is established and technical assistance is available. Healthy procurement policies can ensure that food purchased by a jurisdiction supports its public health efforts. Published by Elsevier Inc.

    2012-01-27

    Gang homicides account for a substantial proportion of homicides among youths in some U.S. cities; however, few surveillance systems collect data with the level of detail necessary to gang homicide prevention strategies. To compare characteristics of gang homicides with nongang homicides, CDC analyzed 2003-2008 data from the National Violent Death Reporting System (NVDRS) for five cities with high levels of gang homicide. This report describes the results of that analysis, which indicated that, consistent with similar previous research, a higher proportion of gang homicides than other homicides involved young adults and adolescents, racial and ethnic minorities, and males. Additionally, the proportion of gang homicides resulting from drug trade/use or with other crimes in progress was consistently low in the five cities, ranging from zero to 25%. Furthermore, this report found that gang homicides were more likely to occur with firearms and in public places, which suggests that gang homicides are quick, retaliatory reactions to ongoing gang-related conflict. These findings provide evidence for the need to prevent gang involvement early in adolescence and to increase youths' capacity to resolve conflict nonviolently.

  6. Effects of Harbor Modification on Crescent City, California's Tsunami Vulnerability

    2011-06-01

    More damaging tsunamis have impacted Crescent City, California in historic times than any other location on the West Coast of the USA. Crescent City's harbor has undergone significant modification since the early 20th century, including construction of several breakwaters, dredging, and a 200 × 300 m2 small boat basin. In 2006, a M w 8.3 earthquake in the Kuril Islands generated a moderate Pacific-wide tsunami. Crescent City recorded the highest amplitudes of any tide gauge in the Pacific and was the only location to experience structural damage. Strong currents damaged docks and boats within the small boat basin, causing more than US 20 million in damage and replacement costs. We examine how modifications to Crescent City's harbor may have affected its vulnerability to moderate tsunamis such as the 2006 event. A bathymetric grid of the basin was constructed based on US Army Corps of Engineers soundings in 1964 and 1965 before the construction of the small boat basin. The method of splitting tsunamis was used to estimate tsunami water heights and current velocities at several locations in the harbor using both the 1964-1965 grid and the 2006 bathymetric grid for the 2006 Kuril event and a similar-sized source along the Sanriku coast of Japan. Model velocity outputs are compared for the two different bathymetries at the tide gauge location and at six additional computational sites in the harbor. The largest difference between the two grids is at the small boat basin entrance, where the 2006 bathymetry produces currents over three times the strength of the currents produced by the 1965 bathymetry. Peak currents from a Sanriku event are comparable to those produced by the 2006 event, and within the boat basin may have been higher. The modifications of the harbor, and in particular the addition of the small boat basin, appear to have contributed to the high current velocities and resulting damage in 2006 and help to explain why the 1933 M w 8.4-8.7 Sanriku tsunami

    Flood response in an urban area is the product of interactions of spatially and temporally varying rainfall and infrastructures. In urban areas, however, the complex sub-surface networks of tunnels, waste and storm water drainage systems are often inaccessible, pose challenges for modeling and prediction of the drainage infrastructure performance. The increased availability of open data in cities is an emerging information asset for a better understanding of the dynamics of urban water drainage infrastructure. This includes crowd sourced data and community reporting. A well-known source of this type of data is the non-emergency hotline "311" which is available in many US cities, and may contain information pertaining to the performance of physical facilities, condition of the environment, or residents' experience, comfort and well-being. In this study, seven years of New York City 311 (NYC311) call during 2010-2016 is employed, as an alternative approach for identifying the areas of the city most prone to sewer back up flooding. These zones are compared with the hydrologic analysis of runoff flooding zones to provide a predictive model for the City. The proposed methodology is an example of urban system phenomenology using crowd sourced, open data. A novel algorithm for calculating the spatial distribution of flooding complaints across NYC's five boroughs is presented in this study. In this approach, the features that represent reporting bias are separated from those that relate to actual infrastructure system performance. The sewer backup results are assessed with the spatial distribution of runoff in NYC during 2010-2016. With advances in radar technologies, a high spatial-temporal resolution data set for precipitation is available for most of the United States that can be implemented in hydrologic analysis of dense urban environments. High resolution gridded Stage IV radar rainfall data along with the high resolution spatially distributed land cover data are

    2013-07-01

    Full Text Available In this article the strong effect of forming a corporate identity in city branding is  studied. It is emphasized that by strong identity and image acquisition cities distinguish by their unique branding elements rather than global city imposition  hat is carried out by globalization pressure. According to the opinions that perceive globalization as an absolute fact, cities like Istanbul have to articulate  to this new system. In this way of thinking, it is inevitable to suffer in McLuhan’s  “global village”. However creating strategies for powerful image and branding of a city can be a leading factor against global city imposition. Keeping up with the same method of creating a “corporate” identity, the image of the cities has to be managed by the symmetric communication with all the actors. By this way  globalization can be used as an opportunity instead of threat.

    Mexico City is one of the most populated cities in the world with almost 22 million inhabitants, located at an altitude of 2200 m. The old city was founded on an ancient lake and the zone is known by its high seismicity; indoor radon determination is an important public health issue. In this paper the data of indoor radon levels in Mexico City, measured independently by two research groups, both using Nuclear Track Detector systems but different methodologies, are correlated. The measurements were done during similar exposure periods of time, at family houses from the political administrative regions of the city. The results indicate a correlation coefficient between the two sets of data of R=0.886. Most of the differences between the two sets of data are inherent to houses having extreme (very high or very low indoor radon) included in the statistics of each group. The total average indoor radon found in Mexico City considering the two methods was 87Bqm{sup -3}.

    Seaman, R; Mitchell, R; Dundas, R; Leyland, A H; Popham, F

    2015-10-16

    Glasgow's low life expectancy and high levels of deprivation are well documented. Studies comparing Glasgow to similarly deprived cities in England suggest an excess of deaths in Glasgow that cannot be accounted for by deprivation. Within Scotland comparisons are more equivocal suggesting deprivation could explain Glasgow's excess mortality. Few studies have used life expectancy, an intuitive measure that quantifies the between-city difference in years. This study aimed to use the most up-to-date data to compare Glasgow to other Scottish cities and to (i) evaluate whether deprivation could account for lower life expectancy in Glasgow and (ii) explore whether the age distribution of mortality in Glasgow could explain its lower life expectancy. Sex specific life expectancy was calculated for 2007-2011 for the population in Glasgow and the combined population of Aberdeen, Dundee and Edinburgh. Life expectancy was calculated for deciles of income deprivation, based on the national ranking of datazones, using the Scottish Index of Multiple Deprivation. Life expectancy in Glasgow overall, and by deprivation decile, was compared to that in Aberdeen, Dundee and Edinburgh combined, and the life expectancy difference decomposed by age using Arriaga's discrete method. Life expectancy for the whole Glasgow population was lower than the population of Aberdeen, Dundee and Edinburgh combined. When life expectancy was compared by national income deprivation decile, Glasgow's life expectancy was not systematically lower, and deprivation accounted for over 90 % of the difference. This was reduced to 70 % of the difference when carrying out sensitivity analysis using city-specific income deprivation deciles. In both analyses life expectancy was not systematically lower in Glasgow when stratified by deprivation. Decomposing the differences in life expectancy also showed that the age distribution of mortality was not systematically different in Glasgow after accounting for deprivation

    This article addresses the impact of globalization on the contemporary society, particularly the role of the city that is becoming increasingly important. Three distinct yet intertwine aspects such as decentralization, technology, and para diplomacy become antecedent of competitiveness of the city. A city has more power and authority in creating wealth and prosperity of the society by utilizing technology. The smart city, in addition to the importance of technology as enabler, we argue that possessing the sophisticated technology and apply it towards the matter is not enough. The smart city needs to build smart diplomacy at the sub-national level. In this article, we extend the discussion about smart city by proposing a new framework of smart city diplomacy as one way to integrate information technology, public policy and international relations which will be the main contribution to literature and practice.

  15. Sustainability for Shrinking Cities | Science Inventory | US EPA

    Science.gov (United States)

    Shrinking cities are widespread throughout the world despite the rapidly increasing global urban population. These cities are attempting to transition to sustainable trajectories to improve the health and well-being of urban residents, to build their capacity to adapt to changing conditions and to cope with major events. The dynamics of shrinking cities are different than the dynamics of growing cities, and therefore intentional research and planning around creating sustainable cities is needed for shrinking cities. We propose research that can be applied to shrinking cities by identifying parallel challenges in growing cities and translating urban research and planning that is specific to each city’s dynamics. In addition, we offer applications of panarchy concepts to this problem. The contributions to this Special Issue take on this forward-looking planning task through drawing lessons for urban sustainability from shrinking cities, or translating general lessons from urban research to the context of shrinking cities. Humans are rapidly becoming an urban species, with greater populations in urban areas, increasing size of these urban areas, and increasing number of very large urban areas. As a consequence, much of what we know about cities is focused on how they grow and take shape, the strains that their growth puts on city infrastructure, the consequences for human and nonhuman inhabitants of these cities and their surroundings, and the policies which can

    Many city governments choose to supply more developable land and transportation infrastructure with the hope of attracting people and businesses to their cities. However, like those in Taiwan, major cities worldwide suffer from traffic congestion. This study applies the system thinking logic of the causal loops diagram (CLD) model in the System Dynamics (SD) approach to analyze the issue of traffic congestion and other issues related to roads and land development in Taiwan's cities. Comparing the characteristics of development trends with yearbook data for 2002 to 2013 for all of Taiwan's cities, this study explores the developing phenomenon of unlimited city sprawl and identifies the cause and effect relationships in the characteristics of development trends in traffic congestion, high-density population aggregation in cities, land development, and green land disappearance resulting from city sprawl. This study provides conclusions for Taiwan's cities' sustainability and development (S&D). When developing S&D policies, during decision making processes concerning city planning and land use management, governments should think with a holistic view of carrying capacity with the assistance of system thinking to clarify the prejudices in favor of the unlimited developing phenomena resulting from city sprawl.

    Full Text Available Through the establishment of the Coordination Group for the City of Zagreb Spatial Management IT System, the City of Zagreb has become actively involved in the wider global community by setting up the Zagreb Spatial Data Infrastructure (ZSDI service. In the City of Zagreb, many bodies of city administration use and create spatial data and services daily in their work. All are ZSDI users and obviously have to make data mutually available. Without spatial data and services, it would be impossible to manage space effectively, plan city development, monitor the situation on the ground, or carry out many other activities. This paper gives an overview of ZSDI set-up activities so far, as well as plans for the future.

    International Nuclear Information System (INIS)

    Harris, Paul G.; Chow, Alice S.Y.; Symons, Jonathan

    2012-01-01

    The diversity of greenhouse gas (GHG) accounting methodologies currently utilized by cities around the world make meaningful comparisons of their emissions almost impossible. Consequently, the 2010 United Nations International Standard for Determining Greenhouse Gas Emissions for Cities promotes a “harmonized protocol for quantifying the GHG emissions attributable to cities and local regions.” The UN's common standard has important implications for comparison, benchmarking and policy assessment related to energy policies. This paper uses Hong Kong as a case study to illustrate these implications. Hong Kong's per capita contribution to GHG emissions are among the highest in the world, yet the local government's official statistics indicate emissions that are far below those reported by most affluent economies. This discrepancy arises from a reporting methodology that does not require inclusion of GHG emissions linked to consumption of imported goods or emissions from aviation and shipping. The Hong Kong case reveals that current inventories do not provide sufficient information to guide policymaking related to energy and climate change. They also do not provide adequate information for comparing policies of cities internationally. Alternative emissions-reporting standards that focus more on pollution from consumption will create avenues for more effective climate-related policies. - Highlights: ► Flawed GHG inventory methodologies can lead cities to adopt misguided policies. ► Diverse GHG inventory methodologies make meaningful comparisons among cities difficult. ► A Hong Kong case study highlights that GHG inventories can misrepresent cities' climate impacts. ► City inventories often exclude GHG emissions linked to imports, aviation and shipping. ► The International Standard for Determining GHG Emissions for Cities can assist climate policy.

    Urban areas are increasingly at risk from climate change with negative impacts predicted for human health, the economy and ecosystems. These risks require responses from cities, to improve the resilience of their infrastructure, economy and environment to climate change. Policymakers need to understand what is already being spent on adaptation so that they can make more effective and comprehensive adaptation plans. Through the measurement of spend in the newly defined 'Adaptation Economy' we analysis the current efforts of 10 global megacities in adapting to climate change. These cities were chosen based on their size, geographical location and their developmental status. The cities are London, Paris, New York, Mexico City, Sao Paulo, Beijing, Mumbai, Jakarta, Lagos and Addis Ababa. It is important to study a range of cities in different regions of the world, with different climates and at different states of socio-economic development. While in economic terms, disaster losses from weather, climate and geophysical events are greater in developed countries, fatalities and economic losses as a proportion of GDP are higher in developing countries. In all cities examined the Adaptation Economy is still a small part of the overall economy accounting for a maximum of 0.3% of the Cities total GDP (GDPc). The differences in total spend are significant between cities in developed and rapidly emerging countries, compared to those in developing countries with a spend ranging from £16 million to £1,500 million. Comparing key sub sectors, we demonstrate that there are distinctive adaptation profiles with developing cities having a higher relative spend on health, while developed cities have a higher spend on disaster preparedness, ICT and professional services. Comparing spend per capita and as a percentage of GDPc demonstrates even more clearly disparities between the cities in the study; developing country cities spend half as much as a proportion of GPCc in some cases, and

    Some of the local government in Indonesia claimed they already created a smart city. Mostly the claim based of IT utilization for their governance. In general, a smart city definition is to describe a developed urban area that creates sustainable economic development and high quality of life by excelling in multiple key; economy, mobility, environment, people, living, and government. For public services, the law guarantees good governance by setting the standard for e-government implicitly including for local government or a city. Based on the arguments, this research tries to test the condition of e-government of the Indonesian city in 34 provinces. The purpose is to map e-government condition by measuring indicators of smart government, which are: transparent governance and open data for the public. This research is departing from public information disclosure law and to correspond with the existence law. By examining government transparency, the output of the research can be used to measure the effectiveness of public information disclosure law and to determine the condition of e-government in local government in which as part of a smart city.

    Full Text Available Taking into consideration that the development of strong partnerships involving local citizens, civil society, the local economy and the various levels of government is an indispensable element for an Integrated Sustainable Urban Development, our paper is focusing on the role of an appropriate urban networking in the relationship with the objectives of a smart city. In this context, the Romanian good practices - as Oradea city - are worth to mention. In compliance with Europe 2020 Strategy’s objectives there will be discussed the particularities of urban networking in order to strengthen the resilience of cities, and to ensure synergies amongst the investments supported by European Structural and Investment (ESI funds. According to economic literature the urban network is not a funding instrument but a way for cities to share feedback on the use of these new approaches. The estimated results of our research are related to the conclusion that the urban networks act as a forum for capacity building and exchange between the cities pioneering new techniques and developing integrated investments.

    Full Text Available Urban freight transport is a challenge for Brazilian cities due to the lack of adequate planning for freight flow movement. Public managers also show negligence and a lack of awareness when dealing with urban logistics. Decision-support data on urban freight transport are still scarce, despite being of fundamental value to economic development. With this in mind, this paper presents problems and solutions regarding urban freight transport in Brazilian cities. Data were obtained through a survey conducted in nine cities and analysed by means of descriptive statistics and the successive intervals method. Additionally, a cluster analysis was performed to identify patterns regarding the typical characteristics of each city in order to compare and generalise the perception of retailers regarding problems and solutions at the national level. The results indicate divergent opinions among retailers from different cities, even from cities with similar socioeconomic profiles and urban dynamics. The municipalities which demonstrated the most similarities were (i Betim and Niteroi, in the Southeast of Brazil; (ii Palmas and Quixada, in the North and Northeast, respectively; and (iii Palmas and Caruaru, also in the North and Northeast. The results reinforce the importance of studying the local context and involving stakeholders in the process of planning urban logistics solutions.

  5. Are Feed-in Tariffs suitable for promoting solar PV in New Zealand cities?

    2013-01-01

    Feed-in Tariffs (FITs) implemented by city councils in the USA have proven an effective means of stimulating installation of renewable-electricity generation capacity at a local level, and may also be effective for New Zealand cities. Though New Zealand has a high proportion of electricity generated renewably, this is mostly from centralized hydroelectricity plants. The suitability of city-level FITs for promoting solar photovoltaic panels in New Zealand is examined. Findings suggest that FITs, with rates obtained using the cost-of-generation method, could be implemented in New Zealand cities at rates comparable to those in successful FIT schemes internationally. The unique structure of New Zealand's liberalized electricity market, however, is likely to make financing FIT schemes at city-level more complex than the equivalent situation in the USA. Benefits of introducing such schemes will include the possibility for purchasers of solar PV systems to calculate returns on investment over the long term, and the streamlining of the grid connection process by reducing the number of authorities involved. - Highlights: • Results pertain to New Zealand city councils implementing FITs. • FIT rates similar to those in other countries provide sufficient investor incentive. • FITs could greatly increase investor security and ease grid connection. • Electricity market structure precludes financing through burden-sharing

    2015-10-31

    Brigham City owns and operates its own municipal power system which currently includes several hydroelectric facilities. This project was to update the efficiency and capacity of current hydro production due to increased water flow demands that could pass through existing generation facilities. During 2006-2012, this project completed efficiency evaluation as it related to its main objective by completing a feasibility study, undergoing necessary City Council approvals and required federal environmental reviews. As a result of Phase 1 of the project, a feasibility study was conducted to determine feasibility of hydro and solar portions of the original proposal. The results indicated that the existing Hydro plant which was constructed in the 1960’s was running at approximately 77% efficiency or less. Brigham City proposes that the efficiency calculations be refined to determine the economic feasibility of improving or replacing the existing equipment with new high efficiency equipment design specifically for the site. Brigham City completed the Feasibility Assessment of this project, and determined that the Upper Hydro that supplies the main culinary water to the city was feasible to continue with. Brigham City Council provided their approval of feasibility assessment’s results. The Upper Hydro Project include removal of the existing powerhouse equipment and controls and demolition of a section of concrete encased penstock, replacement of penstock just upstream of the turbine inlet, turbine bypass, turbine shut-off and bypass valves, turbine and generator package, control equipment, assembly, start-up, commissioning, Supervisory Control And Data Acquisition (SCADA), and the replacement of a section of conductors to the step-up transformer. Brigham City increased the existing 575 KW turbine and generator with an 825 KW turbine and generator. Following the results of the feasibility assessment Brigham City pursued required environmental reviews with the DOE and

  10. The scaling of urban surface water abundance and impairment with city size

    2018-03-01

    Urbanization alters surface water compared to nonurban landscapes, yet little is known regarding how basic aquatic ecosystem characteristics, such as the abundance and impairment of surface water, differ with population size or regional context. This study examined the abundance, scaling, and impairment of surface water by quantifying the stream length, water body area, and impaired stream length for 3520 cities in the United States with populations from 2500 to 18 million. Stream length, water body area, and impaired stream length were quantified using the National Hydrography Dataset and the EPA's 303(d) list. These metrics were scaled with population and city area using single and piecewise power-law models and related to biophysical factors (precipitation, topography) and land cover. Results show that abundance of stream length and water body area in cities actually increases with city area; however, the per person abundance decreases with population size. Relative to population, impaired stream length did not increase until city populations were > 25,000 people, then scaled linearly with population. Some variation in abundance and impairment was explained by biophysical context and land cover. Development intensity correlated with stream density and impairment; however, those relationships depended on the orientation of the land covers. When high intensity development occupied the local elevation highs (+ 15 m) and undeveloped land the elevation lows, the percentage of impaired streams was less than the opposite land cover orientation (- 15 m) or very flat land. These results show that surface water abundance and impairment across contiguous US cities are influenced by city size and by biophysical setting interacting with land cover intensity.

    Full Text Available A smart city is rising as an approach and strategy to reduce the troubles produced by rapid urbanization and the growth of urban population. Although, cities continue to develop and purify their social, economic and environmental goals along with the strategies to achieve them, this phenomenon has been discussed by little research yet. However, due to the requiring immediate action or attention for practical application of the principles of smart cities, city authorities, stakeholders and local communities need to know the current reality of their city and where development is being attained in their systems. Therefore, constructing a framework for smart cities assessment will help share or exchange the newcomer strong and weak points, and emphasize where actual development is taking place and update a plan for future developments. Moreover, this assessment is able to assist cities prioritizes actions. This paper developed a guiding assessment framework for smart cites that will help the creating, carefully choosing and priorities of crucial indicators. These indicators can then show the way to the smart cites performance assessment and monitoring. Drawing on the investigation of an extensive and wide collection of literature from a variety of disciplinary areas and based on the conceptual literature on smart cities, in addition to interviews this study identify a good tool to help recognizing of virtual achievement of smart city. Furthermore, it is significant to be taken into consideration in assessing smart city smartness level.

    This research investigates the maximum potential energy that can be made available by efficiently installing photovoltaic (PV) systems on buildings throughout a city, from the central business district (CBD) out to low density suburbs. The purpose of this is to evaluate the contribution that electricity from PVs can make to reduce the electricity load of a city, supply the needs of a mixture of building types, reduce peak electricity demand and contribute towards the charging of electric vehicles (EVs). Having established the maximum potential, intermediate stages in PV penetration can be backcasted. The results indicate that low dense suburbia is not only the most efficient collector of solar energy but that enough excess electricity can be generated to power daily transport needs of suburbia and also contribute to peak daytime electrical loads in the city centre. This challenges conventional thinking that suburbia is energy inefficient. While a compact city may be more efficient for the internal combustion engine vehicles, a dispersed city is more efficient when distributed generation of electricity by PVs is the main energy source and EVs are the means of transport. - Highlights: • A method for analysing the contribution of photovoltaics to a whole city is described. • Maps are presented that compare net-metering of energy throughout a city. • These maps provide a useful tool for renewable energy policy in urban areas. • In the case of Auckland, suburbia can be a net energy provider to the city. • Suburbia can produce electricity to charge all its electric vehicle travel needs

    Full Text Available Large Polish cities are currently dealing with an increasing significance of downtown areas, extending outside of the city centers (meaning the area directly surrounding the city square. The downtown alone seems to influence the fate of entire cities, facilitating their success or contributing to their failure. A good demographic, social and economic condition of a downtown, its positive image and the dynamic development of the part of the city perceived as the business and administration centre and a meeting place of residents and tourists, contribute to the image and potential of the whole city to a great extent. Changes in urban surroundings, the signs of which may be observed in spatial, aesthetic, architectural, urban-planning and socio-economic aspects, determine the functioning and condition of local real estate markets. Whether potential buyers consider the real estate attractive depends on the assessment of its significant features, of which transaction price is representative. The main research objective of the article is the identification, assessment and interpretation of differences in prices registered in the years 2009-2014 in downtown residential real estate markets. These considerations have been referred to analogical phenomena within the entire cities under examination. The detailed research objective is an attempt to explain the sources of individual reactions of the analyzed real estate markets in downtown areas. The cities under research include: Bydgoszcz, Kalisz, Toruń and Wrocław. The authors applied quantitative analysis (statistical, comparative to transaction data registered in local residential real estate markets.

    hour of the period of interest, the situation best matching the winds observed at weather stations within the GRAMM model domain. Detailed emission inventories available for the two cities serve as inputs for the dispersion simulations. For Zurich, an extremely detailed inventory with 60 source categories for 9 air pollutants including line, point and area sources has been generated by the city authorities, allowing us to simulate the contribution of different sources separately. The annual emissions are scaled with temporal profiles of diurnal, day-of-week and seasonal variability taking local information (e.g. heating and traffic activity) into account whenever possible. For the two cities, 10 years of NOx and PM concentrations have been simulated with hourly temporal and 5 m spatial resolution. We demonstrate the good performance of the model system compared to regular air pollution observations, and its potential for quantifying trends in emissions and imissions and for accurately assessing human exposure at the city scale.

    We surveyed background level of radioactive contamination in city area of Osaka before combusting the wide area disposal of disastrous debris at a municipal waste incineration plant of Osaka city. The debris was caused by Tohoku district great earthquake disaster and suspected to be contaminated with radionuclides released from the Fukushima Daiichi Nuclear Power Plants. We also investigated radioactivity in incineration ash of municipal waste incineration plants and of sewage treatment plants, as well as in water clarifier sludge of potable water treatment plants, and evaluated the accumulation and cleansing of radioactive materials via the reverse logistic function of the city. Radioactive caesium deposited in Osaka city area was estimated to be approximately 4.3 GBq from the concentrations observed in the monthly fallout, whereas that collected as municipal wastes and sewage was estimated to be approximately 0.9 GBq a year in 2011. Even two years after the accident, "1"3"4Cs, which is the evidence of the Fukushima Daiichi Nuclear Power Plant accident, had been detected in the municipal wastes at a level comparable to the activities found just after the accident, however, the radioactive caesium concentration in fallout measured in the Osaka city area had decreased below a detection limit after May 2012. Introduction of materials contaminated with radioactive caesium from outside the city area was suspected because the observed contamination level was inexplicable by that of observed in the environmental wastes such as pruned branches which are contaminated by with the fallout in city area of Osaka.

    2013-12-01

    Full Text Available Large port cities like Shanghai, Amsterdam and Rio de Janeiro are key cogwheels in international logistics and transport networks but also serve as showcases for the rest of the world; as such, they constitute strategic assets for the host country´s economy and international influence. Historically, a city and its port often developed independently, through sometimes contradictory or even confrontational policies. Today, the growing number of usage disputes over increasingly coveted coastal areas is prompting local managers to incorporate urban and port-related issues in overarching planning programs. In particular, planning of the sea front and the buffer zone between the port and the city must contribute decisively to the deployment of more effective, cleaner transport services for the port city as a whole. In general, one of the key global challenges for planners and decision-makers consists in integrating sustainable development goals (environmental and social components, as well as the stimulation of industrial competitiveness into urban planning. In this context the PHEBUS research group has initiated an international program of research to develop innovative methods and tools that can help territorial stakeholders to design, evaluate, compare and ultimately choose development scenarios for the future of their port cities. The main themes are addressed via a multidisciplinary systems approach on the scale of a coastal urban area with an industrial and port complex. In particular, the themes include sea front planning, the city-port interface, energy optimization (e.g. the introduction and sharing of renewable energies, risk resilience, climate change and multimodal, clean transport.

    Over the last decade, climate change has moved from being the concern of few to a widely recognized threat to humanity itself and the natural environment. The 1990s were the warmest decade on record, and ever-increasing atmospheric levels of greenhouse gases such as carbon dioxide (CO/sub 2/), could, if left unchecked lead to serious consequences globally, including increased risks of droughts, floods and storms, disruption to agriculture, rising sea levels and the spread of disease. The contribution of anthropogenic emissions of carbon dioxide has been recognized as the principal cause of the atmospheric changes that drive these climate trends. Globally, buildings are the largest source of indirect carbon emissions. In 2000, the UK Royal Commission on Environmental Pollution estimated that in order to stabilise carbon emissions at levels, which avoid catastrophic alterations in the climate, we would have to reduce emissions from the built environment by at least 60% by 2050 and 80% by 2100 relative to 1997 levels. Studies of the Oxford Ecohouse have demonstrated that it is not difficult to reduce carbon emissions from houses by 60% or more through energy efficiency measures, but it is only possible to reach the 90% level of reductions required by using renewable energy technologies. Solar energy technologies have been the most successfully applied of all renewable to date largely because they are the only systems that can be incorporated easily into the urban fabric. In addition, the short fossil fuel horizons that are predicted (c. 40 years left for oil and 65 years for gas) will drive the markets for solar technologies. For these reasons, the cities of the future will be powered by solar energy, to a greater or lesser extent, depending on the city form and location. In recognition of the need to move rapidly towards a renewable energy future, a group of international cities, including Oxford, have started the Solar City Network. In this paper we outline the

    A study on the data of the physique investigated in teenagers was carried out between Hong Kong and inland cities to compare their cardiopulmonary endurance and muscular fitness. Results revealed that cardiopulmonary endurance in school teenagers of both sex at different ages in inland cities was better than that in Hong Kong. Muscular strength and endurance of sports performance of teenagers, except for standing long jump, in Hong Kong were weaker than that in inland cities. It suggests that attention should be paid to the involvement of teenagers in physical education with the increase of people's living standard.

  10. Experiencing the Tourist City. The European Capital of Culture in Re-Designing City Routes

    Full Text Available Assuming that providing memorable experiences is the raison d’être of tourism industry, the city envisaged as a tourist destination should assume the tourist’s perspective when designing the settings and the most significant activities of a visit. Cities are facing new challenges, noticeably the globalisation of economies, the growing importance of the visual and the symbolic that define the current trends of consumption and the attractiveness of a place. Culture and events play a strategic role when designing innovative and appealing tourism experiences. The European Capital of Culture (ECoC is an international event which represents a unique opportunity for the cities to stand out in this globalised and competitive scenario. This paper focuses on the study of Pécs, European Capital of Culture 2010, and it aims to study the influence of this event on the design of city tourism routes. A survey by questionnaire was administered to tourists before and during ECoC in Pécs. Respondents indicated in open-ended questions the most outstanding points in their visit to the city, on which were designed the relevant circuits and routes during that tourist experience in Pécs. Data analysis was performed using the statistical software STAS.

    Full Text Available It’s obvious today that the city we knew has changed: grew far beyond its old limits, multiplied its centres, specialized some areas, expanded its influence with help from infrastructure networks. The rising of the information society, the changing in the economic and technologic paradigms, the globalization (as a process of spacial and temporal reorganization at a world level, reflected deeply in the functioning and demands made to the contemporary city. And if discourses about Space, continue to prevail in architectural and urban culture that we receive everyday, today’s architecture and city are strongly conditioned by different ways to “see” Time. More than temporal concepts schemes, the determinant for “space production” is the way how these temporal conceptions influence and determine the action the city project and its meaning. Analysing several examples of paradigmatic thinking, from recent theory on contemporary city, we’ll study statements and solutions for problems that rise from these new spatial and temporal transformations.

    2014-01-01

    Solar photovoltaic (PV) installations have been growing rapidly in the United States over the last few years, incentivized by policies from federal, state and local governments. The complex relationships between solar policies at multiple levels of government and solar deployment are questions of importance to policy makers and scholars. Extant literature on solar policies pays less attention to the role of local governments and policies than to their federal and state counterparts. Local governments and policies play indispensable roles in the deployment of solar PVs. This paper studies the multilevel governance of solar development in the U.S. by evaluating the relative effectiveness of state and local policy tools in stimulating solar PV installations, with an emphasis on local solar policies. With a regression analysis on a national sample of 186 U.S. cities, we find that cities with local financial incentives deploy 69% more solar PV capacities than cities without such policies. We also find that cities subject to RPS requirements have 295% more solar PV capacity, compared with cities not regulated by state RPS. - Highlights: • This study evaluates state and local solar PV policies. • State RPS has positive impacts on local solar PV capacity. • Local financial incentives matter for solar PV deployment

  15. A Comparison of Vacancy Dynamics between Growing and Shrinking Cities Using the Land Transformation Model

    Directory of Open Access Journals (Sweden)

    Jaekyung Lee

    2018-05-01

    Full Text Available Every city seeks opportunities to spur economic developments and, depending on its type, vacant land can be seen as a potential threat or an opportunity to achieve these developments. Although vacant land exists in all cities, the causes and effects of changes in vacant land can differ. Growing cities may have more vacant land than shrinking cities because of large scale annexation. Meanwhile, depopulation and economic downturn may increase the total amount of vacant and abandoned properties. Despite various causes of increase and decrease of vacant land, the ability to predict future vacancy patterns—where future vacant parcels may occur—could be a critical test to set up appropriate development strategies and land use policies, especially in shrinking cities, to manage urban decline and regeneration efforts more wisely. This study compares current and future vacancy patterns of a growing city (Fort Worth, TX, USA and a shrinking city (Chicago, IL, USA, by employing the Land Transformation Model (LTM to predict for future vacant lands. This research predicts and produces possible vacancy pattern scenarios by 2020 and deciphers the ranking of determinants of vacant land in each city type. The outcomes of this study indicate that the LTM can be useful for simulating vacancy patterns and the causes of vacancy vary in both growing and shrinking cities. Socio-economic factors such as unemployment rate and household income are powerful determinants of vacancy in a growing city, while physical and transportation-related conditions such as proximity to highways, vehicle accessibility, or building conditions show a stronger influence on increasing vacant land in a shrinking city.

  16. Benefits of Greenery in Contemporary City

    Science.gov (United States)

    Virtudes, Ana

    2016-10-01

    Greenery has always played an important role in the construction of cities. The need for green spaces has been present at city level since ancient times. However, the description of the evolutionary process of form and function of urban green spaces as it has developed from antiquity depends greatly upon the different roles played by these places throughout history. Nowadays, given that the main part of the world population is living in cities, it can be said that greenery has a strategic importance in the contemporary urban fabric. Therefore, urban design solutions should always consider both buildings and vegetation as being defining city's elements. However, the city is currently dominated by building structures which are detrimental to green spaces, causing problems of congestion and pollution. The most recent and compulsory Portuguese urban rehabilitation principles emphasize the improvement of sustainability. It is, therefore, critical to draw attention to this area and find innovative solutions in this domain, especially with regards the integration of vegetation in historical areas. In this sense, this research aims to present an approach about the importance of greenery in cities, referring some examples of green spaces as landmarks in the urban historiography. It is also focused on the benefits of green spaces in dense urban areas and their contribution for the sustainability of the cities.

    In view of the enormous social and environmental changes at the global level, more and more cities worldwide have directed their development strategies towards smart policies aimed at sustainable mobility, energy upgrading of the building stock, increase of energy production from renewable sources, improvement of waste management and implementation of ICT infrastructures. The goal is to turn into Smart Cities, able to improve the quality of life of their inhabitants by offering a lasting opportunity for cultural, economic and social growth within a healthy, safe, stimulating and dynamic environment. After an overview of the role of cities in climate changes and environmental pollution worldwide, the article provides an up to date definition of Smart City and of its main expected features, focussing on technology innovation, smart governance and main financing and support programs. An analysis of the most interesting initiatives at the international level pursued by cities investigating the three main areas of Green Buildings, Smart grid-Smart lighting, and Smart mobility is given, with the objective to offer a broad reference for the identification of development sustainable plans and programs at the urban level within the current legislative framework.

    Abstract The hypothesis in this paper is that the ideas and principles of linear cities, emerging in late 19th century and developing during the first half of 20th century, can be looked upon in a forward looking perspective as contributions to contemporary urban strategies. Throughout the 20th...... century, the major tendency has been the population’s relocation from the country to the city. In developing countries, the development has clearly been towards major cities while growth in industrialised countries has spread out through the entire urban system, including minor urban developments. A key...... concentration of people in a smaller area, without necessarily being followed by increased interaction by way of increased infrastructure. Both situations are interdependent through globalisation and in the long term, neither situation is sustainable. The relevance of discussing linear city principles today...

    2016-06-01

    Full Text Available The right to the city, defined by Henri Lefebvre in 1967 as the right of urban inhabitants to build, decide and create the city, and make of it a privileged space of anti-capitalist struggle, is again at the center of political debate. Social scientists, social movements, international aid agencies and States take it as a benchmark for policy analysis and to discuss the urban changes in contemporary capitalist cities. This article discusses the assumptions made by Lefebvre in 1967 and the transformation that the concept of right to the city has had from authors such as David Harvey, Edward Soja and Ana Fani Alessandri Carlos.

    Determine the fluoride content in all the wells that supply drinking water to the city of Aguascalientes, Mexico, in order to establish the population's degree of exposure. The fluoride content of the 126 wells that supply drinking water to the city of Aguascalientes was determined, using the SPADNS method, in accordance with two Mexican regulations, NMX-AA-77-1982 and NMX-014-SSAI-1993. Using that data, we created fluoride isopleth maps showing the distribution of fluoride concentrations in the water supplies for the city of Aguascalientes. We also estimated exposure doses for the city's inhabitants. The mean analysis uncertainty was 3.9%. Seventy-three wells had a fluoride concentration of" 1.5 mg/L, which was the maximum permissible value set by the Mexican standards then in effect. All the maximum exposure doses surpassed the minimum risk level set by Agency for Toxic Substances and Disease Registry (ATSDR) of the Department of Health and Human Services of the United States of America. In the children under 1 year of age, even the minimum does was slightly higher than the ATSDR risk level. From estimating the fluoride exposure doses caused by water consumption in the city of Aguascalientes and comparing those doses with ones from other states in Mexico, we concluded that the fluoride intake in Aguascalientes represents a potential risk for inhabitants' health. The fluoride content of the city's drinking water should be reduced to 0.69 mg/L.

    2016-12-01

    Full Text Available Integrating green spaces such as parks and gardens into the physical landscape of cities has been identified to enhance the health and wellbeing of urban dwellers. This paper assesses the state of green spaces in Kumasi city (Ghana, once known as the garden city of West Africa. Using a case study approach, a mixture of qualitative research techniques were employed whilst a set of eight themes were put together to guide the assessment. In all, green spaces were found to be in poor state. With the exception of conservation and heritage theme, the remaining seven themes that were used for the assessment all found the green spaces to be in poor state. It is therefore recommended that there should be an attitudinal change towards the maintenance of green spaces, the application of a collaborative governance approach, and priority giving to green spaces in all development agendas by city authorities.

  4. Measuring level of friendliness of smart city: a perceptual study

    2018-03-01

    Currently the concept of smart city comes not only at the level of discussion, but some cities have stepped in the stage of implementation. Many of promised benefits will be met for the needs of urban residents if the city applies this concept. Conversely, many professionals and scholars are still in doubt about readiness of a city in the application of this concept. Dimension of friendliness of the real city certainly will have some limitations in a smart city that relies more on interactions with information and communication technology (ICT). This new paradigm becomes background of this paper in viewing the friendliness dimension of a smart city based on city residents’ perceptions. This paper uses case of 2 cities that have different level of readiness in the application of smart city. They are Yogyakarta City and Magelang City, both are located in Central Java. The method applied in this paper is quantitative method based on perceptual answer of respondents structured in a Likert Scale. Importance Performance Analysis (IPA) is then used to look at the attributes of smart city’s dimension which will show the relationship of the level of city friendliness and the level of city readiness in an application of smart city. The result briefly shows that the level of city sensitivity in the application of smart city is very influential in viewing the friendliness of the city. The city that is better equipped to meet the needs of its population according to the dimensions of the smart city based on its existing characteristics has higher friendliness. Time period of applying a smart city concept as the City of Yogyakarta has done longer before Magelang City, is not a guarantee that the city then has a better level of friendliness. The urban citizens have appropriate affective aspect to articulate between what they need and what the city has provided.

  5. The Uses of Big Data in Cities.

    Bettencourt, Luís M A

    2014-03-01

    There is much enthusiasm currently about the possibilities created by new and more extensive sources of data to better understand and manage cities. Here, I explore how big data can be useful in urban planning by formalizing the planning process as a general computational problem. I show that, under general conditions, new sources of data coordinated with urban policy can be applied following fundamental principles of engineering to achieve new solutions to important age-old urban problems. I also show that comprehensive urban planning is computationally intractable (i.e., practically impossible) in large cities, regardless of the amounts of data available. This dilemma between the need for planning and coordination and its impossibility in detail is resolved by the recognition that cities are first and foremost self-organizing social networks embedded in space and enabled by urban infrastructure and services. As such, the primary role of big data in cities is to facilitate information flows and mechanisms of learning and coordination by heterogeneous individuals. However, processes of self-organization in cities, as well as of service improvement and expansion, must rely on general principles that enforce necessary conditions for cities to operate and evolve. Such ideas are the core of a developing scientific theory of cities, which is itself enabled by the growing availability of quantitative data on thousands of cities worldwide, across different geographies and levels of development. These three uses of data and information technologies in cities constitute then the necessary pillars for more successful urban policy and management that encourages, and does not stifle, the fundamental role of cities as engines of development and innovation in human societies.

    Full Text Available Objective: The aim of this study was to examine the synchrony of influenza epidemics between Hong Kong and Shenzhen, two neighboring subtropical cities in South China. Methods: Laboratory-confirmed influenza data for the period January 2006 to December 2016 were obtained from the Shenzhen Center for Disease Control and Prevention and the Department of Health in Hong Kong. The population data were retrieved from the 2011 population censuses. The weekly rates of laboratory-confirmed influenza cases were compared between Shenzhen and Hong Kong. Results: Unsynchronized influenza epidemics between Hong Kong and Shenzhen were frequently observed during the study period. Influenza A/H1N1 caused a more severe pandemic in Hong Kong in 2009, but the subsequent seasonal epidemics showed similar magnitudes in both cities. Two influenza A/H3N2 dominant epidemic waves were seen in Hong Kong in 2015, but these epidemics were very minor in Shenzhen. More influenza B epidemics occurred in Shenzhen than in Hong Kong. Conclusions: Influenza epidemics appeared to be unsynchronized between Hong Kong and Shenzhen most of the time. Given the close geographical locations of these two cities, this could be due to the strikingly different age structures of their populations. Keywords: Influenza epidemics, Synchrony, Shenzhen, Hong Kong

    2011-04-15

    We aimed to determine the level of antimicrobial consumption by adult inpatients at Auckland City Hospital (Auckland, New Zealand) and to compare our findings with those in other developed nations. We used the computerised records of the central Auckland District Health Board (ADHB) pharmacy to measure the amount of antimicrobials dispensed to inpatients (excluding psychiatric units, day stay units and outpatient clinics) during 2006 to 2009. The total weight of each antimicrobial dispensed was used to determine the number of defined daily doses (DDDs) dispensed. The Information Management and Technical Services department of ADHB provided data on the number of admissions and inpatient days, and these data, together with information from the 2006 census, were used to calculate antimicrobial consumption for adult inpatients measured in DDDs/100 admissions, DDDs/100 inpatient days and DDDs/1000 population. Total antimicrobial consumption by adult inpatients increased from 74 DDDs/100 inpatient days in 2006 to 80.3 DDDs/100 inpatient days in 2009. The level of consumption did not vary greatly with the season. The total level of consumption was very similar to that seen in adult inpatients in hospitals in Australia and Scandinavian countries. The level of consumption of fluoroquinolones, third or fourth generation cephalosporins, carbapenems and vancomycin (antimicrobial classes that are not available for unrestricted use in Auckland City Hospital) was comparable to or less than that seen in adult inpatients in hospitals in Australia or Scandinavian countries. Beta-lactamase susceptible penicillins (such as benzyl penicillin and phenoxymethylpenicillin) comprised a relatively small proportion of total penicillin use and beta-lactamase inhibitor combinations (predominantly amoxicillin/clavulanate) a relatively large proportion of total penicillin use, when compared with Scandinavian hospitals. The antimicrobial stewardship programme at Auckland City Hospital has

    Adriana ZAIŢ

    2016-06-01

    Full Text Available In the endeavor of analyzing urban development perspectives, the current paper aims to find out how warmth and competence stereotypes would operate in the case of a city, predicting its future, as a direct consequence of people's positive or negative feelings and actions. Results of such analyses would be of strategic importance, knowing that various aspects of urban development (from tourism to business, well-being, active population growth and talents retention depend on people’s decisions to visit that city, to invest, to work, to study, to settle down there, or to simply spread positive opinions about it. Therefore, relying on the well-known SCM -stereotype content model, the paper adapts previous warmth and competence scales, and develops a customized research instrument for analyzing connections between people's perceptions and the mental labels attached to a specific city. Considering warmth and competence dimensions, as well as the other variables of interest such as status, cooperation and competition, we use an exploratory procedure for item selection followed by a Q-sorting analysis for scale content validation. The paper adds to the literature in two main ways. It firstly advances an integrative view that connects the theories from social psychology, communication and branding with those from urban development. Secondly, it offers a content validated measurement instrument, as a necessary departure point for future analyses meant to identify challenges and to predict the potential for development of smart and sustainable cities.

  16. City Walks and Tactile Experience

    Directory of Open Access Journals (Sweden)

    Mădălina Diaconu

    2011-01-01

    Full Text Available This paper is an attempt to develop categories of the pedestrian’s tactile and kinaesthetic experience of the city. The beginning emphasizes the haptic qualities of surfaces and textures, which can be “palpated” visually or experienced by walking. Also the lived city is three-dimensional; its corporeal depth is discussed here in relation to the invisible sewers, protuberant profiles, and the formal diversity of roofscapes. A central role is ascribed in the present analysis to the formal similarities between the representation of the city by walking through it and the representation of the tactile form of objects. Additional aspects of the “tactile” experience of the city in a broad sense concern the feeling of their rhythms and the exposure to weather conditions. Finally, several aspects of contingency converge in the visible age of architectural works, which record traces of individual and collective histories.

  17. Methods for specifying spatial boundaries of cities in the world: The impacts of delineation methods on city sustainability indices.

    Science.gov (United States)

    Uchiyama, Yuta; Mori, Koichiro

    2017-08-15

    The purpose of this paper is to analyze how different definitions and methods for delineating the spatial boundaries of cities have an impact on the values of city sustainability indicators. It is necessary to distinguish the inside of cities from the outside when calculating the values of sustainability indicators that assess the impacts of human activities within cities on areas beyond their boundaries. For this purpose, spatial boundaries of cities should be practically detected on the basis of a relevant definition of a city. Although no definition of a city is commonly shared among academic fields, three practical methods for identifying urban areas are available in remote sensing science. Those practical methods are based on population density, landcover, and night-time lights. These methods are correlated, but non-negligible differences exist in their determination of urban extents and urban population. Furthermore, critical and statistically significant differences in some urban environmental sustainability indicators result from the three different urban detection methods. For example, the average values of CO 2 emissions per capita and PM 10 concentration in cities with more than 1 million residents are significantly different among the definitions. When analyzing city sustainability indicators and disseminating the implication of the results, the values based on the different definitions should be simultaneously investigated. It is necessary to carefully choose a relevant definition to analyze sustainability indicators for policy making. Otherwise, ineffective and inefficient policies will be developed.

    The book discusses the concept of the smart city, and is based on a multi-service and multi-sectoral approach to urban planning, including various urban functions and the human capital of cities. The work is divided into three parts. The first is an introductory section which covers definitions, policies and tools used at European level for the development and classification of a smart city. The second presents a selection of examples of Western and Eastern communities, which experienced technologies and strategies that have made them smart. The third describes in detail the main three possible approaches (economical, technological and social) to the smart city concept which are the focus ambits of the holistic concept of smart city. The work provides a good overview of the concept of smart city, and also offers a critical analysis of the various approaches to smart cities, in order to provide tools to develop solutions that address the smart development of cities with an approach as multi-sectoral as possibl...

    The aim of our article is an attempt to present the concept of urbanity that has been shaped throughout centuries along with the development of European civilisation and now entered a new phase of social production of space based on cultural dimensions. The future of the majority of World’s population is connected currently with the urban life with the assumption that qualitative characteristics of life in the 21st century define the quality of civilisation itself. Contrary to many scientists’ predictions of the decline of the city and urbanity, new reviving urban projects, social local activities and everyday urbanism appear which are connected with redefinition of the city as a community. The rebirth of cities, currently referred to as “urban renaissance”, “urban resurgence” or “urban revival”, can be also defined in terms of new urbanity regarded as an insightful and creative attitude towards the city and its culture. The elementary order of things was determined in the last decades not by the space but by the time and its acceleration and simultaneously the role of architecture alters. The course of thinking about the city is changing from a single space-time city towards a personalised city, based on individual identities and corresponding places in the physical and virtual space. That can mean a new role of the city in the creation of urbanity. In the era of advanced communication technologies, a question arises about the ontological status of the city when the emphasis is placed on independence and individuality in interactions between people. Social life becomes detached from traditional spatial patterns and practices. We are interested in the urbanity understood in the wider context of cultural urban studies which are focused on new ways of organising the communication space and social relations. We will refer in this article to the values constitutive for the city and urbanity that guided the idea of the city since the dawn of time as well

  20. Innovation in City Governments

    Lewis, Jenny M; Ricard, Lykke Margot; Klijn, Erik Hans

    Innovation has become an important focus for governments around the world over the last decade, with greater pressure on governments to do more with less, and expanding community expectations. Some are now calling this ‘social innovation’ – innovation that is related to creating new services...... that have value for stakeholders (such as citizens) in terms of the social and political outcomes they produce. Innovation in City Governments: Structures, Networks, and Leadership establishes an analytical framework of innovation capacity based on three dimensions: Structure - national governance...... project in Copenhagen, Barcelona and Rotterdam. The book provides major new insights on how structures, networks and leadership in city governments shape the social innovation capacity of cities. It provides ground-breaking analyses of how governance structures and local socio-economic challenges...
