CO2 is the main anthropogenic greenhouse gas and its reduction plays a decisive role in reducing global climate change. As a CO2 elimination method, the present work is based on chemical absorption using aqueous ammonia as solvent. A CFD (computational fluid dynamics) model was developed to study CO2 capture in a single droplet. The objective was to identify the main mechanisms responsible for CO2 absorption, such as diffusion, solubility, convection, chemical dissociation, and evaporation. The proposed CFD model takes into consideration the fluid motion inside and outside the droplet. It was found that diffusion prevails over convection, especially for small droplets. Chemical reactions increase the absorption by up to 472.7% in comparison with physical absorption alone, and evaporation reduces the absorption up to 41.9% for the parameters studied in the present work.

In recent years, the climate change (CC) and urban heat island (UHI) effects are becoming serious problems, affecting people’s life and health, especially in hot summer. For large cities such as Tokyo and Osaka in Japan, the UHI effect is particularly intense. It is known that about 40% of urban anthropogenic heat comes from buildings in large cities. To reduce the anthropogenic heat of buildings is an important countermeasure to this problem. Strategies for UHI mitigation include urban ventilation, urban greening, green roof, highly reflective (HR) roads, and HR building envelopes, etc. Among these mitigation strategies, the research on HR building envelopes has been carried out globally. However, it is not clear that how the HR building envelopes affect the urban outdoor environment temperature and indoor thermal loads of urban buildings which is directly related to the selection of heating, ventilation and air conditioning (HVAC) system. Thus, this study aims to evaluate the effect of solar reflectivity of building envelopes varied from 0.1 to 0.9, on the outdoor environment temperature and indoor thermal loads of buildings located on Osaka University Suita Campus, Japan, using Computational Fluid Dynamics (CFD) and numerical analysis.

According to the literature, both advanced and developing countries are facing several challenges due to the lack of clean energy and emissions of CO2 leading to climate change. Especially in the built environment, energy efficient buildings are highly desirable to save energy without affecting occupant’s health while providing an acceptable indoor environment and thermal conditions. The use of insulation, passive solar heating, and HVAC systems can contribute to improve the indoor thermal comfort. In the present study, a numerical simulation model is developed to evaluate the human comfort factors in a simulated indoor environment. The CFD model considers the thermal interaction of humans with the indoor environment. Ventilation and a heat source are added to model a workspace for evaluating indoor air temperature and human comfort factors. Indices like predicted mean vote (PMV) and predicted percentage dissatisfaction (PPD) are evaluated to assess thermal sensation of human body when adding and removing a heat source in the model office (i.e., radiator).

This presented paper focuses on the design and evaluation of the concept of concentrated solar heaters for segmental heat accumulators, which are designed to cover the energy needs of selected communities in terms of food preparation without the need for fossil fuels, which have a negative impact not only on the climate but especially on health. The proposed device is based on the traditional method of food preparation in the so-called earth oven; however, the fire-heated stones are replaced with heat accumulators heated by solar radiation. This approach eliminates the need to change common and long-term habits of food preparation for selected communities. The device connects solar vacuum heat pipes, a solar radiation concentrator, and heat accumulators. The concept was evaluated based on computational fluid dynamics (CFD) analysis with the use of a transient simulation of selected operating situations in three geographical locations. The results showed a significant temperature increase of the heat accumulators, where in the most effective case the temperature increased up to 227.23 °C. The concept was also evaluated based on a calorimetric analysis of the system consisting of heat accumulators and food. The resulting temperature in the considered case reached the pasteurization temperature necessary for safe and healthy food preparation.

Occupational Safety and Health (OSH) issues in the urban rail transport industry need to be given full attention due to the factors of the instability of declining occupational accident rate, increasing number of passengers each year, and the pressure of technological development; in addition, the day-to-day operations also involve the public and various interested communities. Organization is one of the factors that influence worker safety and health status. This study aimed to propose a factor model of the organizational safety climate towards a better safety and health status for Malaysian urban rail industry. This quantitative study used a questionnaire randomly distributed to Malaysian rail system workers. A total of 441 workers in the operation and maintenance division were involved in this study. Confirmatory factor analysis (CFA) using IBM SEM-AMOS was conducted to determine the reliability and validity of the observed variables and the latent variables. This study proved that all four dimensions identified as safety communication, safety training, safety support system, and safety value represents the organizational safety climate. Following the analysis, an organizational safety climate model is successfully developed. This factor model aims to be used in the context of rail management studies to measure the safety climate of their organization, thereby improving the safety level of the workers within the organization.

Working in today’s healthcare environment, with its increasing emphasis on profits, can result in our forgetting why we are here. This reductionistic climate is the antithesis of mental health and caring. To resurrect the culture of caring and help us reconnect with ourselves as nurses, the Center for Caring (CFC) at University Health System, based on the principles of Dr. Jean Watson’s Transpersonal Nursing, was established in 2003. During the first annual CFC retreat, the nurses created group Mandalas. This paper explores how the process of creating Mandalas gave participants the freedom to connect with themselves and each other, by living, imagining, and sharing Transpersonal Nursing in their lives.

Serbia is situated at Balkan Peninsula, and currently majority of the territory is under warm temperate ? fully humid climate type with warm summers (Cfb type, according to Koppen-Geiger Climate Classification). Observed changes in climate conditions since 1961 until present time show significant increase in temperature change and change in precipitation patterns. Disturbances in heat conditions, which are recorded to affect human health, agricultural production and forest eco?system, are priority in climate change analysis and application in adaptation plan?ning. Future change analysis show accelerated increase of temperature by the end of the 21st century, which proves the needs for immediate measures for mitigation of negative impacts. Temperature increase averaged over the territory of Serbia is 1.2?C for the period 1996-2015 with respect to the period 1961-1980, with highest increase of maximum daily temperature during the summer season, 2.2?C. Using high resolution multi-model ensemble approach for analysis of the future changes with respect to the base period 1986-2005, in compliance with Intergovernmental Panel on Climate Change (IPCC) fifth assessment report (AR5), it is estimated that temperature may increase by 1.9?C according to Representative Concentration Pathway 4.5 (RCP4.5) scenario and by 4.4?C according to RCP8.5 by the end of the century. Spatial distribution of temperature increase, intensification of high pre?cipitation events and decrease of summer precipitation, show intrusion of subtropi?cal climate over the Serbia and increase of high temperature and high precipitation risks. Results presented in this paper, using high-resolution multi-model ensemble approach, provide climate change information for short term to long term planning in different sectors of economy and preservation of human health and environment.

Fossil fuel vehicles, emitting air toxics into the atmosphere, impose a heavy burden on the economy through additional health care expenses and ecological degradation. Air pollution is responsible for millions of deaths and chronic and acute health problems every year, such as asthma and chronic obstructive pulmonary disease. The fossil-fuel-based transportation system releases tons of toxic gases into the atmosphere putting human health at risk, especially in urban areas. This analysis aims to determine the economic burden of environmental and health impacts caused by Highway 401 traffic. Due to the high volume of vehicles driving on the Toronto Highway 401 corridor, there is an annual release of 3771 tonnes of carbon dioxide equivalent (CO2e). These emissions are mainly emitted onsite through the combustion of gasoline and diesel fuel. The integration of electric and hydrogen vehicles shows maximum reductions of 405–476 g CO2e per vehicle-kilometer. Besides these carbon dioxide emissions, there is also a large amount of hazardous air pollutants. To examine the impact of air pollution on human health, the mass and concentrations of criteria pollutants of PM2.5 and NOx emitted by passenger vehicles and commercial trucks on Highway 401 were determined using the MOVES2014b software. Then, an air dispersion model (AERMOD) was used to find the concentration of different pollutants at the receptor’s location. The increased risk of health issues was calculated using hazard ratios from literature. Finally, the health cost of air pollution from Highway 401 traffic was estimated to be CAD 416 million per year using the value of statistical life, which is significantly higher than the climate change costs of CAD 55 million per year due to air pollution.

Objective: The present study was undertaken to determine the overall prevalence of nutritional status among young adult of VIT University, Vellore with impact of psycho-somatic changes, primary health and climate change among fresh admission. Material & Methods: Study measured data on height and weight of adults aged 17-23 years of the newly admitted students (n=157; Girls=87 & Boys=70). One commonly used indicator i.e., body mass index (BMI; kg/m2) was used to evaluate the nutritional status of subjects. Based on BMI, chronic energy deficiency (CED) and obesity were determined accordingly. Results: The mean BMI varies from 21.828 to 23.223 among girls between 17-23 years of age while 23.493 to 24.265 among boys of 17-19 years of age. The mean magnitudes of BMI are between 23.497 and 22.563 respectively among students of 17 to 23 years old. The nutritional status of 57.32% of fresher is normal with the estimated BMI while 11.46 % are suffering from under-nutrition and 31.21% are with obesity. Overall prevalence of CED was (11.3 %). Among 87 girls, 58 (67.5%) and 27.1% of 70 boys are psychologically stressed. The study has also intervened the shifting of time management and utilization before and after to VIT system. Students either gained or lost their bodyweight during the first semester of academic courses; a total of 51 students (17 girls and 34 boys) lost their weight by 1-10 kg while a total of 36 students gained weight. Conclusion: Acclimatization has brought changes among studied students those who came from distant states.

The intensity and duration of hot weather and the number of extreme weather events, such as heatwaves, are increasing, leading to a growing need for space cooling energy demand. Together with the building stock’s low energy performance, this phenomenon may also increase households’ energy consumption. On the other hand, the low level of ownership of cooling equipment can cause low energy consumption, leading to a lack of indoor thermal comfort and several health-related problems, yet increasing the risk of energy poverty in summer. Understanding future temperature variations and the associated impacts on building cooling demand will allow mitigating future issues related to a warmer climate. In this respect, this paper analyses the effects of change in temperatures in the residential sector cooling demand in 2050 for a case study of nineteen cities across seven countries: Cyprus, Finland, Greece, Israel, Portugal, Slovakia, and Spain, by estimating cooling degree days and hours (CDD and CDH). CDD and CDH are calculated using both fixed and adaptive thermal comfort temperature thresholds for 2020 and 2050, understanding their strengths and weaknesses to assess the effects of warmer temperatures. Results suggest a noticeable average increase in CDD and CDH values, up to double, by using both thresholds for 2050, with a particular interest in northern countries where structural modifications in the building stock and occupants’ behavior should be anticipated. Furthermore, the use of the adaptive thermal comfort threshold shows that the projected temperature increases for 2050 might affect people’s capability to adapt their comfort band (i.e., indoor habitability) as temperatures would be higher than the maximum admissible values for people’s comfort and health.

PurposeConducted with a staff of 562 persons working in the health sector in Quebec, mainly nurses, the purpose of this paper is to test the indirect effects of psychosocial safety climate (PSC) on workarounds through physical fatigue, cognitive weariness and emotional exhaustion as mediators.Design/methodology/approachThe structural equation method, namely CFA, was used to test the structure of constructs, the reliability and validity of the measurement scales as well as model fit. To test the mediation effects, Hayes’s PROCESS (2013) macro and 95 percent confidence intervals were used and 5,000 bootstrapping re-samples were run. The statistical treatments were carried out with the AMOS software V.24 and SPSS v.22.FindingsThe results based on bootstrap analysis and Sobel’s test demonstrate that physical fatigue, cognitive weariness and emotional exhaustion mediate the relationship between PSC and safety workarounds.Practical implicationsThe study has important practical implications in detecting blocks and obstacles in the work processes and decreasing the use of workaround behaviors, or in converting their negative consequences into positive contributions.Originality/valueTo the authors’ knowledge, this is the first study to examine the relationship between PSC, burnout and workaround behaviors. These results could contribute to a better understanding of this construct of workarounds and how to deal with it. Moreover, the test of the concepts of PSC in this study provides support for the theory of “conservation of resources” by proposing an extension of this theory.

The shortage of vegetation cover alongside urban structures and land hardscape in cities causes an artificial temperature increase in urban environments known as the urban heat island (UHI) effect. The artificial heat stress in cities has a particular threat for usability and health-safety of outdoor living in public space. Australia may face a likely 3.8°C increase in surface temperature by 2090. Such an increase in temperature will have a severe impact on regional and local climate systems, natural ecosystems, and human life in cities. This paper aims to determine the patterns of the UHI effect in micro-scale of Adelaide metropolitan area, South Australia. The urban near-surface temperature profile of Adelaide was measured along a linear east-west cross-section of the metropolitan area via mobile traverse method between 26 July 2013 and 15 August 2013. Results indicate that the while the maximum UHI effect occurs at midnight in the central business district (CBD) area in Adelaide, the afternoon urban warmth has more temperature variations (point-to-point variation), especially during the late afternoon when local air temperature is normally in its peak. Thus, critical measurement of heat-health consequences of the UHI effect need to be focused on the afternoon heat stress conditions in UHIs rather than the commonly known night time phenomenon. This mobile traverse urban heat study of Adelaide supports the hypothesis that the UHI effect varies in the built environment during daily cycles and within short distances. Classical UHI measurements are commonly performed during the night – when the urban-rural temperature differences are at their maximum. Thus, they fall short in addressing the issue of excess heat stress on human participants. However, having thermally comfortable urban microclimates is a fundamental characteristic of healthy and vibrant public spaces. Therefore, urban planning professionals and decision makers are required to consider diurnal heat stress alongside nocturnal urban heat islands in planning healthy cities. The results of this article show that the diurnal heat stress varies in the built environment during daily cycles and within short distances. This study confirms that the maximum urban heat stress occurs during late afternoon when both overall temperature and daily urban warmth are at their peak. Literature indicates that diurnal heat stress peaks in hard-landscapes urban settings while it may decrease in urban parklands and near water bodies. Therefore, urban greenery and surface water can assist achieving more liveable and healthy urban environments (generalisation requires further research). A better understanding of daily urban warmth variations in cities assists urban policy making and public life management in the context of climate change.

Extreme climate events have significant impacts on various sectors such as agriculture, ecosystem, health and energy. The issue would lead to economic losses as well as social problems. This study aims to investigate the trend of extreme precipitation in Sumatera Island based on observed data during 30-year period, 1981–2010. There are ten indices of climate extreme as defined by ETCCDMI, which were tested in this study, including PRCPTOT, SDII, CDD, CWD, R10, R50, R95p, R99p, Rx1day and Rx5day. Then, the trend was analyzed based on the Mann-Kendall statistic, performed on the time series of precipitation data. The result shows that there was positive trend of extreme precipitation found in most stations over Sumatera, either statistically significant or insignificant. In each extreme precipitation indices, the number of observed stations indicating the insignificant change is higher than the significant one. This research also found that some indices including SDII, Rx1day, R50, R95p and R99p, showed a significantly-positive trend followed by a higher intensity of wetter and heavier events of extreme precipitation over Sumatera. On the other hand, the wet spell (CWD) index shows a negative trend (α=0.05).

The Yellow River Basin (YLRB) and Yangtze River Basin (YZRB) are heavily populated, important grain-producing areas in China, and they are sensitive to climate change. In order to study the temporal and spatial distribution of extreme climate events in the two river basins, seven extreme temperature indices and seven extreme precipitation indices were projected for the periods of 2010–2039, 2040–2069, and 2070–2099 using data from 16 Coupled Model Intercomparison Project Phase 5 (CMIP5) models, and the delta change and reliability ensemble averaging (REA) methods were applied to obtain more robust ensemble values. First, the present evaluation indicated that the simulations satisfactorily reproduced the spatial distribution of temperature extremes, and the spatial distribution of precipitation extremes was generally suitably captured. Next, the REA values were adopted to conduct projections under different representative concentration pathway (RCP) scenarios (i.e., RCP4.5, and RCP8.5) in the 21st century. Warming extremes were projected to increase while cold events were projected to decrease, particularly on the eastern Tibetan Plateau, the Loess Plateau, and the lower reaches of the YZRB. In addition, the number of wet days (CWD) was projected to decrease in most regions of the two basins, but the highest five-day precipitation (Rx5day) and precipitation intensity (SDII) index values were projected to increase in the YZRB. The number of consecutive dry days (CDD) was projected to decrease in the northern and western regions of the two basins. Specifically, the warming trends in the two basins were correlated with altitude and atmospheric circulation patterns, and the wetting trends were related to the atmospheric water vapor content increases in summer and the strength of external radiative forcing. Notably, the magnitude of the changes in the extreme climate events was projected to increase with increasing warming targets, especially under the RCP8.5 scenario.

ABSTRACT Many dwellings in warm-humid climates attain a comfortable environment by natural ventilation. The opening of exterior windows for ventilation allows the entry of insects along with the breeze. As a remedy, occupants install insect-proof screens on windows resulting in reduced airflow into the interior. This study attempts to evaluate the air change effectiveness and thermal comfort in a residential kitchen with insect-proof screens. A kitchen with insect-proof screens on the windows is compared with a case without insect-proof screens. Numerical simulation was conducted using ANSYS Fluent 2019 R2. The insect-proof screen is modelled as a porous media. The air velocity and temperature measurements were validated by measurements in a real scenario. The presence of insect-proof screens reduced the air velocity inside the space by 82%. However, the airflow pattern in the case with screens was more uniformly distributed. The mean age of the air was considerably higher in the case with insect-proof screens, which in turn resulted in a reduced ACE. The presence of an insect-proof screen resulted in a Predicted Mean Vote (PMV) of 2.79 indicating a ‘hot’ sensation, whereas in the other case, the comfort vote is only 1.93 indicating a ‘warm’ sensation. The presence of insect-proof screens on windows reduced the air velocity and ventilation efficiency, contributing to increased thermal discomfort in the kitchen.

There are numerous threats to the natural environment that pose a significant risk both to the environment and to human health, including car tires. Thus, there is a need to determine the impact of the life cycle of car tires on the environment, starting with the processes of raw materials acquisition, production, and ending with end-of-life management. Therefore, the authors of this study chose to do research on passenger car tires (size: P205/55/R16). As part of the research, the life cycle assessment (LCA) of traditional car tires was performed with the use of the Eco-indicator 99, cumulative energy demand (CED), and Intergovernmental Panel on Climate Change (IPCC) methods. The level of negative effects was determined for the life cycle of a tire and its particular stages: Production, use, and end of life. The negative impact on the atmosphere, soil, and water, as well as on human health, the environment, and natural resources was also investigated. The results show that the most energy-absorbing stage of a car tire life cycle is the use stage. It was found that the most harmful impact involves the depletion of natural resources and emissions into the atmosphere. Recycling car tires reduces their negative environmental impact during all their life cycle stages.

Emissions from aircraft have adverse effects on the air quality in and around airports, contributing to public health concerns within neighbouring communities. AVIATOR will adopt a multi-level measurement, modelling and assessment approach to develop an improved description and quantification of the relevant aircraft engine emissions, and their impact on air quality under different climatic conditions. Particulate and gaseous emissions in a test cell and on-wing from an in-service aircraft will be measured to determine pollutant plume evolution from the engine and APU exhaust. This will provide an enhanced understanding of primary emitted pollutants, specifically the nvPM and vPM (down to 10nm), and the scalability between the regulatory test cell and real environments. AVIATOR will develop and deploy a proof-of-concept low cost sensor network for monitoring UFP, PM and gaseous species across multiple airports and surrounding communities. Campaigns will be complemented by high-fidelity modelling of aircraft exhaust dynamics, microphysical and chemical processes within the plume. CFD, box, and airport air quality models will be applied, providing validated parameterisations of the relevant processes, applicable to standard dispersion modelling on the local scale. Working with the regulatory community, AVIATOR will develop improved guidance on measuring and modelling the impact of aircraft emissions, and will provide airports and regulators with tools and guidance to improve the assessment of air quality in and around airports.

Car tire manufacturing can be the cause of numerous environmental hazards. Harmful emissions from the production process are an acute danger to human health as well as the environment. To mitigate these unwanted consequences, manufacturers employ the eco-balance analysis at the product designing and development stage, when formulating general development strategies, and increasingly when investigating the entire product lifecycle management process. Since the negative effects of products are considered in a broader range of implications, it has become necessary to extend the traditional scope of analytical interest onto the production, use, and end-of-life stages. This work investigates the manufacturing of passenger car tires executed with traditional and modern manufacturing technologies. The Life Cycle Assessment (LCA) of tires reported in this study involved three LCA methods: Eco-Indicator 99, Cumulative Energy Demand (CED) and the scientific assessment methods developed by the Intergovernmental Panel on Climate Change, Global Warming Potential (IPCC). LCA as a tool for environmental analysis can be carried out for the entire life cycle or its individual phases. The implementation of the work made it possible to demonstrate that as a result of the identification of the main sources of negative impacts, it is possible to propose ways to minimize these impacts in the car tire manufacturing process. The results indicate that the most damaging impact is the depletion of natural resources, which play a key role in the production process of car tires.

Abstract The 1987 Montreal Protocol regulating emissions of chlorofluorocarbons (CFCs) and other ozone-depleting substances (ODSs) was motivated primarily by the harm to human health and ecosystems arising from increased exposure to ultraviolet-B (UV-B) radiation associated with depletion of the ozone layer. It is now known that the Montreal Protocol has helped reduce radiative forcing of the climate system since CFCs are greenhouse gases (GHGs), and that ozone depletion (which is now on the verge of reversing) has been the dominant driver of atmospheric circulation changes in the Southern Hemisphere in the last half century. This paper demonstrates that the Montreal Protocol also significantly protects Earth’s hydroclimate. Using the Community Atmospheric Model, version 3 (CAM3), coupled to a simple mixed layer ocean, it is shown that in the “world avoided” (i.e., with CFC emissions not regulated), the subtropical dry zones would be substantially drier, and the middle- and high-latitude regions considerably wetter in the coming decade (2020–29) than in a world without ozone depletion. Surprisingly, these changes are very similar, in both pattern and magnitude, to those caused by projected increases in GHG concentrations over the same period. It is further shown that, by dynamical and thermodynamical mechanisms, both the stratospheric ozone depletion and increased CFCs contribute to these changes. The results herein imply that, as a consequence of the Montreal Protocol, changes in the hydrological cycle in the coming decade will be only half as strong as what they otherwise would be.

This study aimed to analyze the effect of land cover types to micro-climate of and analyze the effect microclimate to the trees and open land towards amenities environment for human. The City of Bitung has selected as a research site because it planned for mega projects. They are Special Economic Zones (KEK), International Relations Ports and Manado-Bitung Highways. The research used primary and secondary data. The parameters measured for each land cover includes the elements of microclimate namely: Air Temperature, Humidity and Solar Radiation. Data analysis using techniques T test, F test and Analysis of amenities based on the data of air temperature and humidity, it can be calculated by Temperature Humadity Index (THI). The measurement results microclimate taken at four different land cover that is at the city park, Central Business District (CBD), housing and industry. The results of this study prove the hypothesis that there are differences in the average value of the temperature and humidity in the trees, open land. Tree vegetation structures more effectively reduce the air temperature. The structure of the vegetation canopy of trees that have rounded and more densely branched patterns, height being between 6-10 m and serves to overshadow proved more effective in improving amenities in the surrounding area. Based on the value of THI, all land cover both parks, CBD, residential and industrial categorized uncomfortable because the average is at a value> 27. Housing area has very little green space. One of the efforts to improve the quality of the microclimate in order to enhance the user experience is to provide a good environment garden by planting vegetation predominant tree combined with shrubs and grasses to balance and harmonize between buildings and the environment also have aesthetic value. In the industrial area, the high levels of air pollution resulting from the production process so that recommended a good landscape arrangement, by expanding area of town forest and planting vegetation of trees that can absorb large numbers of pollutants result in healthy and fresh air for the region.

Computer Aided Design (CAD) is the reality of today’s architecture. Building Information Modelling (BIM) technique is a great opportunity for communication and data management in virtual space. BIM cloud-based collaboration provides up-to-date information, where project data is at the centre of the process and delivered to the point of the work, makes building workflows more efficient and effective, especially combined with the representational, analytic, and reality capture capabilities. The powerful computer hardware and software can store, transmit and evaluate huge amount of information, but this virtual universe sometimes seems to be too much and too complicated for architects, engineers and contractors (AEC) as single individuals. Widespread awareness of climate change, pollution, depletion of natural resources and huge amount of technical opportunities on global market have triggered professional demands for architects, in sustainable design. Adaptation is a crucial factor in sustainable architecture. Adequacy of decisions depends on the data applied. Systematization of all relevant information, aspects and tools from the very first design step is a crucial part of contemporary architecture. Building design and construction use significant quantities of natural resources and materials and the products we select affect the quality of the spaces we inhabit. Careful consideration of environment and construction parameters from the earliest stage of the design process can have an enormous impact on reducing subsequent operating costs, protecting the nature and our health. Sustainability in architectural design can be more effective based on a newly developing BIM managed integrated multilevel complex approach and database. It should consist of construction and material parameters, requirements and their qualification fitted to the design steps and systemized according to the performance based evaluation and building anatomy.

Green spaces are playing an essential role for ecological balance and for human health in the city as well.They play a fundamental role in providing opportunities for relaxation and enjoying the beauty of naturefor the urban population. Therefore, it is important to produce detailed vegetation maps to assist plannersin designing strategies for the optimisation of urban ecosystem services and to provide a suitable planfor climate change adaptation in one fast growing city. Hence, this research is an investigation using 0.5m high-resolution multispectral Pléiades data integrated with GIS data and techniques to detect andevaluate the spatial distribution of vegetation cover in Erbil City. A supervised classification was usedto classify different land cover types, and a normalised difference vegetation index (NDVI) was usedto retrieve it for the city districts. Moreover, to evaluate the accessibility of green space based on theirdistance and size, a buffer zone criterion was used. The results indicate that the built-up land coverageis 69% and vegetation land cover is 14%. Regarding NDVI results, the spatial distribution of vegetationcover was various and, in general, the lowest NDVI values were found in the districts located in the citycentre. On the other hand, the spatial distribution of vegetation land cover regarding the city districts wasnon-equal and non-concentric. The newly built districts and the districts far from the Central BusinessDistrict (CBD) recorded the lowest vegetation cover compared with the older constructed districts.Furthermore, most of the districts have a lack of access to green spaces based on their distance and size.Distance and accessibility of green areas throughout the city are not equally distributed. The majority ofthe city districts have access to green areas within radius buffer of two kilometres, whereas the lowestaccessibility observed for those districts located in the northeast of the city in particular (Xanzad,Brayate, Setaqan and Raperin). Our study is one of the first investigations of decision-making supportof the spatial planning in a fast-growing city in Iraq and will have a utilitarian impact on developmentprocesses and local and regional planning for Erbil City in the future.

Climate change induced sea-level rise (SLR) is on its increase globally. Regionally the lowlands of China, Vietnam, Bangladesh, and islands of the Malaysian, Indonesian and Philippine archipelagos are among the world’s most threatened regions. Sea-level rise has major impacts on the ecosystems and society. It threatens coastal populations, economic activities, and fragile ecosystems as mangroves, coastal salt-marches and wetlands. This paper provides a summary of the current state of knowledge of sea level-rise and its effects on both human and natural ecosystems. The focus is on coastal urban areas and low lying deltas in South-East Asia and Vietnam, as one of the most threatened areas in the world. About 3 mm per year reflects the growing consensus on the average SLR worldwide. The trend speeds up during recent decades. The figures are subject to local, temporal and methodological variation. In Vietnam the average values of 3.3 mm per year during the 1993-2014 period are above the worldwide average. Although a basic conceptual understanding exists that the increasing global frequency of the strongest tropical cyclones is related with the increasing temperature and SLR, this relationship is insufficiently understood. Moreover the precise, complex environmental, economic, social, and health impacts are currently unclear. SLR, storms and changing precipitation patterns increase flood risks, in particular in urban areas. Part of the current scientific debate is on how urban agglomeration can be made more resilient to flood risks. Where originally mainly technical interventions dominated this discussion, it becomes increasingly clear that proactive special planning, flood defense, flood risk mitigation, flood preparation, and flood recovery are important, but costly instruments. Next to the main focus on SLR and its effects on resilience, the paper reviews main SLR associated impacts: Floods and inundation, salinization, shoreline change, and effects on mangroves and wetlands. The hazards of SLR related floods increase fastest in urban areas. This is related with both the increasing surface major cities are expected to occupy during the decades to come and the increasing coastal population. In particular Asia and its megacities in the southern part of the continent are increasingly at risk. The discussion points to complexity, inter-disciplinarity, and the related uncertainty, as core characteristics. An integrated combination of mitigation, adaptation and resilience measures is currently considered as the most indicated way to resist SLR today and in the near future.References Aerts J.C.J.H., Hassan A., Savenije H.H.G., Khan M.F., 2000.

This work is part of a joint project funded by the Science and Technology Development Fund (STDF) of the Arab republic of Egypt and the Federal Ministry of Education and Research (BMBF) of the Federal Republic of Germany. Continuation of the use of fossil fuels in electricity production systems causes many problems such as: global warming, other environmental concerns, the depletion of fossil fuels reserves and continuing rise in the price of fuels. One of the most promising paths to solve the energy crisis is utilizing the renewable energy resources. In Egypt, high insolation and more than 90 percent available desert lands are two main factors that encourage the full development of solar power plants for thermal and electrical energy production. With an average temperature of about 40 °C for more than half of the year and average annual sunshine of about 3200 hours, which is close to the theoretical maximum annual sunshine hours, Aswan is one of the hottest and sunniest cities in the world. This climatic condition makes the city an ideal place for implementing solar energy harvesting projects from solar updraft tower. Therefore, a Solar Chimney Power Plant (SCPP) is being installed at Aswan City. The chimney height is 20.0 m, its diameter is 1.0m and the collector is a four-sided pyramid, which has a side length of 28.5 m. A mathematical model is used to predict its performance. The model shows that the plant can produce a maximum theoretical power of 2 kW. Moreover, a CFD code is used to analyse the temperature and velocity distribution inside the collector, turbine and chimney at different operating conditions. Static calculations, including dead weight and wind forces on the solar updraft chimney and its solar collector, have been performed for the prototype. Mechanical loading and ambient impact on highly used industrial structures such as chimneys and masts cause lifetime-related deteriorations. Structural degradations occur not only from rare extreme loading events, but often as a result of the ensemble of load effects during the life-time of the structure. A Structural Health Monitoring (SHM), framework for continuous monitoring, is implemented on the solar tower. For the ongoing case study, the types of impacts, the development of the strategic sensor positioning concept, examples of the initially obtained results and further prospects are discussed. Additional wind tunnel tests have been performed to investigate the flow situation underneath the solar collector and inside the transition section. The flow situation in and around the SCPP has been simulated by a combination of the wind tunnel flow and a second flow inside the solar tower. Different wind tunnel velocities and volume flow rates have been measured respectively. Particle Image Velocimetry (PIV) measurements give some indication of the flow situation on the in- and outside of the solar tower and underneath the collector roof. Numerical simulations have been performed with the ANSYS Fluent to validate the experimental tests.

Naturally ventilated buildings play a vital role in mitigating climate change since they produce lower CO2 emissions compared to mechanically ventilated alternatives. Also, occupants have better experiences in naturally ventilated buildings than in mechanically ventilated buildings. However, the application of natural ventilation design is often hindered by extreme weather conditions. To cope with such problems, this paper proposes climate adaptive natural ventilation designs which utilize and adapt to the local climate. The ventilation performance of this design is quantitatively evaluated using a computational fluid dynamics (CFD) approach. The CFD simulation is first validated against experiments and then utilized to reproduce the wind flow inside the building for all four seasons. The evaluation parameters include air changes per hour (ACH), wind speed at the pedestrian level and wind flow patterns indoors. Results showed that this climate adaptive natural ventilation meets the requirements of the Chinese green building assessment standards (GB/T50378-2019) with the highest ACH value of up to 15.8 times per hour. Furthermore, the wind speed at pedestrian level varies from 0.08 m/s to 0.39 m/s. The practice and findings reported in this paper can be useful for future development of sustainable, climate-adaptive buildings.

Difficulty in collecting conventional energy sources as well as their economic benefits including saving of time ,money, fertilizer of higher nutrient value, availability of waste easy and comfortable cooking, health benefits including the reduction diseases and environmental benefits such as saving of forest, clear surrounding were the main motivational factors for this research. However, climate temperatures in areas are too low to enable enough biogas production in small unheated digesters to meet the energy requirements of the institute, so the objectives of were to overcome the problem of energy by solar assisted with the hot water storage tank. In this research mathematical modeling of the solar water heater was designed and the analysis of heat transfer coefficient (losses) through the flat plate collector was done and the techniques that used to reduce these losses also mentioned. From the simulation results; the effect of mesh type on flat plate collector, temperature rise, and pressure drop were characterized including flow type in the laminar and turbulent using CFD approach. The FPC was needed for the preparation of the hot water for the heating of the waste food for the selected fixed dome digester with 2m2 was designed. The effect of water mass flow rate 0.01-0.05kg/s on flat plate collector, temperature rise, pressure drop, and velocity was characterized including the variation of flow types intensity using CFD approach. The optimal temperature to this process was 37 °C.The results obtained have been validated with analytical results

Bats have great economic and environmental importance, including nocturnal insect control, pollination, seed dispersal and forest regeneration. Bats, however, like insects and birds are suffering a precipitous global decline due to anthropogenic causes. Deliberate air pollution in the form of undisclosed tropospheric aerosol geoengineering (TAG) has extremely damaging effects throughout the biosphere. Forensic scientific evidence implicates coal fly ash (CFA), the toxic waste product of coal-burning, as the main constituent of the jet-sprayed particulate trails seen around the world. Coal fly ash is a primary source of the ultrafine and nano-sized particulate fraction of air pollution that adversely impacts human and environmental health. Recently, countless exogenous magnetic pollution particles from combustion sources were found in human brains and heart tissue. Previous studies reveal that aerosolized CFA is a significant factor in the catastrophic global decline of birds and insects. Insects can accumulate aerosolized CFA on their body surfaces and/or ingest CFA particulates that insectivorous bats then consume. Bats are excellent mammalian bioindicators of environmental contaminants and it is known that their tissue contains high levels of metals and persistent organic pollutants. From a review of the literature, we show that the pollutant element ratios in bat tissue and bat guano are consistent with an origin in CFA-type air pollution. These findings suggest that CFA, including its use in covert climate engineering operations, is an unacknowledged factor in the morbidity and mortality of bats. Bats, therefore, are an important "canary in the coal mine" pointing to the urgency of halting covert climate engineering and greatly reducing ultrafine particulate air pollution.

Abstract Background Little research exists on patient safety climate in the prehospital context. The purpose of this article is to test and validate a safety climate measurement model for the prehospital environment, and to explore and develop a theoretical model measuring associations between safety climate factors and the outcome variable transitions and handoffs. Methods A web-based survey design was utilized. An adjusted short version of the instrument Hospital Survey on Patient Safety Culture (HSOPSC) was developed into a hypothetical structural model. Three samples were obtained. Two from air ambulance workers in 2012 and 2016, with respectively 83 and 55% response rate, and the third from the ground ambulance workers in 2016, with 26% response rate. Confirmatory factor analysis (CFA) was applied to test validity and psychometric properties. Internal consistency was estimated and descriptive data analysis was performed. Structural equation modelling (SEM) was applied to assess the theoretical model developed for the prehospital setting. Results A post-hoc modified instrument consisting of six dimensions and 17 items provided overall acceptable psychometric properties for all samples, i.e. acceptable Chronbach’s alphas (.68–.86) and construct validity (model fit values: SRMR; .026–.056, TLI; .95–.98, RMSEA; .031–.052, CFI; .96–.98). A common structural model could also be established. Conclusions The results provided a validated instrument, the Prehospital Survey on Patient Safety Culture short version (PreHSOPSC-S), for measuring patient safety climate in a prehospital context. We also demonstrated a positive relation between safety climate dimensions from leadership to unit level, from unit to individual level, and from individual level on the outcome dimension related to transitions and handoffs. Safe patient transitions and handoffs are considered an important outcome of prehospital deliveries; hence, new theory and a validated model will constitute an important contribution to the prehospital safety climate research.

Besuki Residency well known at agricultural feld. Child and infant mortality in this area is high. Child healthproblems of agricultural-oriented at Besuki Residency no one has research yet. This research uses quantitativemethods that are retrospectives that include child health problems since 2017 until 2018. Quantitative methodis used to collect data on patient characteristics (gender, disease, nursing problems, and age criteria) and illnessto the children’s disease based on agricultural that arise due to activities or agricultural climate. The sampleincluded 807 children at seven hospital scattered in several residency areas using quota sampling technic. Dataanalysis uses confrmatory factor analyze (CFA), with parameter data estimation uses analysis of momentstructures. The result of p-values for health problems to gender = 0.033 (p<0.05), health problems to disease= 0.008 (p<0.05), health problems to nursing problems = 0.000 (p<0.05), health problems to age criteria =0.000 (p<0.05). Fit model value indicates that the model is perfect ft. Child health problems, especially such aspneumonia, diarrhea, and malaria in the agricultural area with an agricultural perspective in the Besuki Residencycan affect gender, disease, nursing problems, and age criteria. So that these health problems require specifchealth interventions or programs according to the characteristics of gender, disease, nursing problems, and agecriteria. The nurse should have a mapping of nursing problems and special agriculture-oriented interventions.

<p>Wellbeing is a multidimensional practical concept that captures a mix of people’s life circumstances. Categorically wellbeing may be divided into three divisions: physical, mental and social wellbeing. As a construct, it may also be perceived as objective wellbeing (relates to material attributes like the amount of wealth, provision of education and health care and social infrastructure) and subjective wellbeing (how people think and feel about their quality of life). In both, the dimension Environment, more specifically the natural environment plays an important key role- both negative and positive. Convention on Biological Diversity (CBD), [1] postulates the ecosystem approach as a means of understanding the roles played by land, water and living resources of the environment (ecological resources) in the life of people as well as integrated management of cultural and biological diversity of the land and the people. Ecosystems are defined as the functional units that are in continual dynamic and complex interaction among plants, animals, water bodies, forest, climate and all other non-living issues in the environment. Ecosystem services are the benefits that people are supposed to or actually obtain from the ecosystem. These inter-phase interactional dynamics is the guiding principle of Ecopsychiatry - where environmental issues influence positively or negatively on the mental health of the people (individual) and the community (collective). Or in other words the impact of environmental specificity (of normal or abnormal state) on the mental health and wellbeing (as also physical and spiritual) of the community or individual. </p><p>The following inter-connected Eco-psychiatric issues that negatively impacted human wellbeing (both physical and mental) are discussed:</p><ol><li>Anthropogenic factors and its impact on population density, land distribution, agricultural production, food insecurity and poverty.</li><li>Attempts to enhance the crop production in a climatic uncertainty and saline field by pesticide over/incorrect -use - resultant in a high incidence of mortality and morbidity (accidental and deliberate self-harm/suicide) of human and pesticide contamination of the environment.</li><li>Nutritional deficiency, animal health and livestock: salinization of water impacted the availability of freshwater fish species, and thus depriving the poor of their protein food source and adversely impacting the income and family integrity.</li><li>Risk factors in human-animal conflicts (tiger/ crocodile/snake attacks) and resultant mortality and morbidity: forest exploration for livelihood measures (fishing, timber-honey-crab-collection) leading to death, family disruption, poverty and overuse of eco-resources.</li><li>Sea-level change and its impact on environment and wellbeing: the health of human, animals, mangrove vegetation, repeated storm and flood, inundation of salt water in agricultural field (high salinity), flood and destruction of life and property is a recurrent event.</li><li>Land erosion and destruction of islands and internal and external migration and displacement of population.</li><li>Climate change and its impact on agriculture, food production, eco-resources and health and emergence of vector-born and water-borne diseases.

Red tide is the term used in Florida (USA) and elsewhere to describe a type of marine harmful algal bloom (HAB) that grows out of control and produces neurotoxins that adversely affect humans, birds, fish, shellfish, and marine mammals. HABs are becoming more abundant, extensive, and closer to shore, and longer in duration than any time in recorded history. Our objective is to review the effects the multifold components of aerosolized coal fly ash as they relate to the increasing occurrences of HABs. Aerosolized coal fly ash (CFA) pollutants from non-sequestered coal-fired power plant emissions and from undisclosed, although “hidden in plain sight,” tropospheric particulate geoengineering operations are inflicting irreparable damage to the world’s surface water-bodies and causing great harm to human health (including lung cancer, respiratory and neurodegenerative diseases) and environmental health (including major die-offs of insects, birds and trees). Florida’s ever-growing toxic nightmare of red tides and blue-green algae is a microcosm of similar activity globally. Atmospheric deposition of aerosol particulates, most importantly bioavailable iron, has drastically shifted the global plankton community balance in the direction of harmful algae and cyanobacterial blooms in fresh and salt water. Proposed geoengineering schemes of iron fertilization of the ocean would only make a bad situation unimaginably worse. Based on the evidence presented here, the global spread of harmful algae blooms will only be contained by rapidly reducing particulate air pollution both by implementation of universal industrial particulate-trapping and by the immediate halting of jet-sprayed particulate aerosols. Corrective actions depend not only on international cooperation, but on ending the deadly code of silence throughout government, academe, and media on the subject of ongoing tropospheric aerosol geoengineering. Long-standing weather control, climate intervention, and geoengineering operations have come to threaten not only all humans but the entire web of life on Earth.

Spotted Fever Rickettsioses (SFR) are diseases caused by bacteria of the genus Rickettsia, and are transmitted mainly by ticks. Its eco-epidemiological scenarios vary spatially, and may also vary over time due to environmental changes. It is the main disease transmitted by ticks to humans in Brazil, with the state of Paraná (PR) having the sixth highest number of notified incidences in the country. However, information is lacking regarding the SFR disease cycles at likely infection sites within PR. During case investigations or environmental surveillance in PR for SFR, 28,517 arthropods were collected, including species known or potentially involved in the SFR cycles, such as Amblyomma sculptum, Amblyomma aureolatum, Amblyomma ovale, Amblyomma dubitatum, Amblyomma parkeri, Ctenocephalides felis felis, and Rhipicephalus sanguineus sensu lato. From these Rickettsia asembonensis, Rickettsia bellii, Rickettsia felis, Rickettsia parkeri strain Atlantic Rainforest and Candidatus Rickettsia paranaensis were detected. Ectoparasite abundance was found to be related with specific hosts and collection environments. Rickettsiae circulation was observed for 48 municipalities, encompassing 16 Health Regions (HR). As for socio-demographic and assistance indicators, circulation occurred largely in the most urbanized HR, with a higher per capita Gross Domestic Product, lower Family Health Strategy coverage, and with a higher ratio of beds in the Unified Health System per thousand inhabitants. For environmental variables, circulation occurred predominantly in HR with a climatic classified as “subtropical with hot summers” (Cfa), and with forest type phytogeographic formations. In terms of land use, circulation was commonest in areas with agriculture, pasture and fields and forest cover. Rickettsiae were circulating in almost all hydrographic basins of PR state. The results of this study provide the first descriptive recognition of SFR in PR, as well as outlining its eco-epidemiological dynamics. These proved to be quite heterogeneous, and analyzed scenarios showed characteristics strongly-associated with the outbreaks, with cases presenting clinical variation in space, so illustrating the complexity of scenarios in PR state. Due to the diversity of the circumstances surrounding SFR infections in PR, public health initiatives are necessary to foster a better understanding of the dynamics and factors effecting vulnerability to SFR in this Brazilian state.

Abstract Background The implementation of evidence-based practice (EBP) in mental health care confers many benefits to patients, and research into factors facilitating the implementation of EBP is needed. As an important factor affecting the implementation of EBP, service providers’ attitudes toward EBP emerged. The Evidence-Based Practice Attitude Scale (EBPAS-36) is an instrument with good psychometric characteristics that measures positive and ambivalent attitudes toward EBP. However, a German version is missing. The present study therefore aims to provide a validated German translation of the EBPAS-36. Methods The scale was translated and back-translated as recommended by standard procedures. German psychotherapists were recruited to participate in an online survey. They provided demographic and professional information, completed the EBPAS-36, the Implementation Climate Scale (ICS) and the Intention Scale for Providers (ISP). Standard item and reliability analyses were conducted. Construct validity was evaluated with exploratory (EFA) and confirmatory factor analyses (CFA) in two subsamples (random split). Convergent validity was tested by predicting a high positive correlation of the EBPAS-36D with two scores of attitudes of the ISP and an interest in EBP score. It was tested whether the EBPAS-36D predicts the intention to use EBP. Results N = 599 psychotherapists participated in the study. The item analyses showed a mean item difficulty of pi = 0.64, a mean inter-item correlation of r = 0.18, and a mean item-total correlation of ritc = 0.40. The internal consistency was very good for the total scale (α = 0.89) and ranged from adequate to very good for the subscales (0.65–0.89), indicating high reliability. The original factor structure showed an acceptable model fit (RMSEA = 0.064 (90% CI = 0.059–0.068); SRMR = 0.0922; AIC = 1400.77), confirming the 12-factor structure of the EBPAS-36. However, a second-order factor structure derived by the EFA had an even better model fit (RMSEA = 0.057 (90% CI = 0.052–0.062); SRMR = 0.0822; AIC = 1274.56). When the EBPAS-36D was entered in a hierarchical regression model with the criterion Intention to use EBP, the EBPAS-36D contributed significantly to the prediction (Change in R2 = 0.28, p < 0.001) over and above gender, age and participants’ report of ever having worked in a university context. Conclusions The present study confirms good psychometric properties and validity of a German version of the EBPAS-36 in a sample of psychotherapists.

When historian Graeme Davison famously declared that “Australia was born urban and quickly grew suburban” (98), he was clearly referring to Melbourne or Sydney, but certainly not Brisbane. Although the Brisbane of 2011 might resemble a contemporary, thriving metropolis, its genealogy is not an urban one. For most of its history, as Gillian Whitlock has noted, Brisbane was “a place where urban industrial society is kept at bay” (80). What distinguishes Brisbane from Australia’s larger southern capital cities is its rapid morphology into a city from a provincial, suburban, town. Indeed it is Brisbane’s distinctive regionalism, with its sub-tropical climate, offering a steamy, fecund backdrop to narratives of the city that has produced a plethora of writing in literary accounts of the city, from author David Malouf through to contemporary writers such as Andrew McGahan, John Birmingham, Venero Armanno, Susan Johnson, and Nick Earls. Brisbane’s lack of urban tradition makes its transformation unique among Australian cities. Its rapid population growth and urban development have changed the way that many people now live in the city. Unlike the larger cities of Sydney or Melbourne, whose inner cities were established on the Victorian model of terrace-row housing on small lots, Brisbane’s early planners eschewed this approach. So, one of the features that gives the city its distinction is the languorous suburban quality of its inner-city areas, where many house blocks are the size of the suburban quarter-acre block, all within coo-ee of the city centre. Other allotments are medium to small in size, and, until recently, housed single dwellings of varying sizes and grandeur. Add to this a sub-tropical climate in which ‘green and growth’ is abundant and the pretty but flimsy timber vernacular housing, and it’s easy to imagine that you might be many kilometres from a major metropolitan centre as you walk around Brisbane’s inner city areas. It is partly this feature that prompted demographer Bernard Salt to declare Brisbane “Australia’s most suburban city” (Salt 5). Prior to urban renewal in the early 1990s, Brisbane was a low-density town with very few apartment blocks; most people lived in standalone houses.From the inception of the first Urban Renewal program in 1992, a joint initiative of the Federal government’s Building Better Cities Program and managed by the Brisbane City Council (BCC), Brisbane’s urban development has undergone significant change. In particular, the city’s Central Business District (CBD) and inner city have experienced intense development and densification with a sharp rise in medium- to high-density apartment dwellings to accommodate the city’s swelling population. Population growth has added to the demand for increased density, and from the period 1995–2006 Brisbane was Australia’s fastest growing city (ABS).Today, parts of Brisbane’s inner city resembles the density of the larger cities of Melbourne and Sydney. Apartment blocks have mushroomed along the riverfront and throughout inner and middle ring suburbs. Brisbane’s population has enthusiastically embraced apartment living, with “empty nesters” leaving their suburban family homes for the city, and apartments have become the affordable option for renters and first home purchasers. A significant increase in urban amenities such as large-scale parklands and river side boardwalks, and a growth in service industries such as cafes, restaurants and bars—a feature of cities the world over—have contributed to the appeal of the city and the changing way that people live in Brisbane.Urbanism demands specific techniques of living—life is different in medium- to high-density dwellings, in populous places, where people live in close proximity to one another. In many ways it’s the antithesis to suburban life, a way of living that, as Davison notes, was established around an ethos of privacy, health, and seclusion and is exemplified in the gated communities seen in the suburbs today. The suburbs are characterised by generosity of space and land, and developed as a refuge and escape from the city, a legacy of the nineteenth-century industrial city’s connection with overcrowding, disease, and disorder. Suburban living flourished in Australia from the eighteenth century and Davison notes how, when Governor Phillip drew up the first town plan for Sydney in 1789, it embodied the aspirations of “decency, good order, health and domestic privacy,” which lie at the heart of suburban ideals (100).The health and moral impetus underpinning the establishment of suburban life—that is, to remove people from overcrowding and the unhygienic conditions of slums—for Davison meant that the suburban ethos was based on a “logic of avoidance” (110). Attempting to banish anything deemed dangerous and offensive, the suburbs were seen to offer a more natural, orderly, and healthy environment. A virtuous and happy life required plenty of room—thus, a garden and the expectation of privacy was paramount.The suburbs as a site of lived experience and cultural meaning is significant for understanding the shift from suburban living to the adoption of medium- to high-density inner-city living in Brisbane. I suggest that the ways in which this shift is captured discursively, particularly in promotional material, are indicative of the suburbs' stronghold on the collective imagination. Reinforcing this perception of Brisbane as a suburban city is a history of literary narratives that have cast Brisbane in ways that set it apart from other Australian cities, and that are to do with its non-urban characteristics. Imaginative and symbolic discourses of place have real and material consequences (Lefebvre), as advertisers are only too well aware. Discursively, city life has been imagined oppositionally from life in the suburbs: the two sites embody different cultural meanings and values. In Australia, the suburbs are frequently a site of derision and satire, characterized as bastions of conformity and materialism (Horne), offering little of value in contrast to the city’s many enchantments and diverse pleasures. In the well-established tradition of satire, “suburban bashing is replete in literature, film and popular culture” (Felton et al xx). From Barry Humphries’s characterisation of Dame Edna Everage, housewife superstar, who first appeared in the 1960s, to the recent television comedy series Kath and Kim, suburbia and its inhabitants are represented as dull-witted, obsessed with trivia, and unworldly. This article does not intend to rehearse the tradition of suburban lampooning; rather, it seeks to illustrate how ideas about suburban living are hard held and how the suburban ethos maintains its grip, particularly in relation to notions of privacy and peace, despite the celebratory discourse around the emerging forms of urbanism in Brisbane.As Brisbane morphed rapidly from a provincial, suburban town to a metropolis throughout the 1990s and early 2000s, a set of metropolitan discourses developed in the local media that presented new ways of inhabiting and imagining the city and offered new affiliations and identifications with the city. In establishing Brisbane’s distinction as a city, marketing material relied heavily on the opposition between the city and the suburbs, implying that urban vitality and diversity rules triumphant over the suburbs’ apparent dullness and homogeneity. In a billboard advertisement for apartments in the urban renewal area of Newstead (2004), images of architectural renderings of the apartments were anchored by the words—“Urban living NOT suburban”—leaving little room for doubt. It is not the design qualities of the apartments or the building itself being promoted here, but a way of life that alludes to utopian ideas of urban life, of enchantment with the city, and implies, with the heavy emphasis of “NOT suburban,” the inferiority of suburban living.The cultural commodification of the late twentieth- and twenty-first-century city has been well documented (Evans; Dear; Zukin; Harvey) and its symbolic value as a commodity is expressed in marketing literature via familiar metropolitan tropes that are frequently amorphous and international. The malleability of such images makes them easily transportable and transposable, and they provided a useful stockpile for promoting a city such as Brisbane that lacked its own urban resources with which to construct a new identity. In the early days of urban renewal, the iconic images and references to powerhouse cities such as New York, London, and even Venice were heavily relied upon. In the latter example, an advertisement promoting Brisbane appeared in the Sydney Morning Herald colour magazine (May 2005). This advertisement represented Brisbane as an antipodean Venice, showing a large reach of the Brisbane river replete with gondolas flanked by the city’s only nineteenth-century riverside building, the Custom’s House. The allusion to traditional European culture is a departure from the usual tropes of “fun and sun” associated with promotions of Queensland, including Brisbane, while the new approach to promoting Brisbane is cognizant of the value of culture in the symbolic and economic hierarchy of the contemporary city. Perhaps equally, the advertisement could be read as ironic, a postmodern self-parodying statement about the city in general. In a nod to the centrality of the spectacle, the advertisement might be a salute to idea of the city as theme park, a pleasure playground and a collective fantasy of escape. Nonetheless, either interpretation presents Brisbane as somewhere else.In other promotional literature for apartment dwellings, suburban living maintains its imaginative grip, evident in a brochure advertising Petrie Point apartments in Brisbane’s urban renewal area of inner-city New Farm (2000). In the brochure, the promise of peace and calm—ideals that have their basis in suburban living—are imposed and promoted as a feature of inner-city living. Paradoxically, while suggesting that a wholesale evacuation and rejection of suburban life is occurring presumably because it is dull, the brochure simultaneously upholds the values of suburbia:Discerning baby boomers and generation X’ers who prefer lounging over latte rather than mowing the quarter acre block, are abandoning suburban living in droves. Instead, hankering after a more cosmopolitan lifestyle without the mind numbing drive to work, they are retreating to the residential mecca, the inner city, for chic shops and a lively dining, arts and theatre culture. (my italics)In the above extract, the rhetoric used to promote and uphold the virtues of a cosmopolitan inner-city life is sabotaged by a language that in many respects capitulates to the ideals of suburban living, and evokes the health and retreat ethos of suburbia. “Lounging” over lattes and “retreating to a residential mecca”[i] allude to precisely the type of suburban living the brochure purports to eschew. Privacy, relaxation, and health is a discourse and, more importantly, a way of living that is in many ways anathema to life in the city. It is a dream-wish that those features most valued about suburban life, can and should somehow be transplanted to the city. In its promotion of urban amenity, the brochure draws upon a somewhat bourgeois collection of cultural amenities and activities such as a (presumably traditional) arts and theatre culture, “lively dining,” and “chic” shops. The appeal to “discerning baby boomers and generation X’ers” has more than a whiff of status and class, an appeal that disavows the contemporary city’s attention to diversity and inclusivity, and frequently the source of promotion of many international cities. In contrast to the suburban sub-text of exclusivity and seclusion in the Petrie Point Apartment’s brochure, is a promotion of Sydney’s inner-city Newtown as a tourist site and spectacle, which makes an appeal to suburban antipathy clear from the outset. The brochure, distributed by NSW Tourism (2000) displays a strong emphasis on Newtown’s cultural and ethnic diversity, and the various forms of cultural consumption on offer. The inner-city suburb’s appeal is based on its re-framing as a site of tourist consumption of diversity and difference in which diversity is central to its performance as a tourist site. It relies on the distinction between “ordinary” suburbs and “cosmopolitan” places:Some cities are cursed with suburbs, but Sydney’s blessed with Newtown — a cosmopolitan neighbourhood of more than 600 stores, 70 restaurants, 42 cafes, theatres, pubs, and entertainment venues, all trading in two streets whose origins lie in the nineteenth century … Newtown is the Catwalk for those with more style than money … a parade where Yves St Laurent meets Saint Vincent de Paul, where Milano meets post-punk bohemia, where Max Mara meets Doc Marten, a stage where a petticoat is more likely to be your grandma’s than a Colette Dinnigan designer original (From Sydney Marketing brochure)Its opening oppositional gambit—“some cities are cursed with suburbs”—conveniently elides the fact that like all Australian cities, Sydney is largely suburban and many of Sydney’s suburbs are more ethnically diverse than its inner-city areas. Cabramatta, Fairfield, and most other suburbs have characteristically high numbers of ethnic groups such as Vietnamese, Korean, Lebanese, and so forth. Recent events, however, have helped to reframe these places as problem areas, rather than epicentres of diversity.The mingling of social groups invites the tourist-flâneur to a performance of difference, “a parade where Yves St Laurent meets Saint Vincent de Paul (my italics), where Milano meets post-punk bohemia,” and where “the upwardly mobile and down at heel” appear in what is presented as something of a theatrical extravaganza. Newtown is a product, its diversity a commodity. Consumed visually and corporeally via its divergent sights, sounds, smells and tastes (the brochure goes on to state that 70 restaurants offer cuisine from all over the globe), Newtown is a “successful neighbourhood experiment in the new globalism.” The area’s social inequities—which are implicit in the text, referred to as the “down at heel”—are vanquished and celebrated, incorporated into the rhetoric of difference.Brisbane’s lack of urban tradition and culture, as well as its lack of diversity in comparison to Sydney, reveals itself in the first brochure while the Newtown brochure appeals to the idea of a consumer-based cosmopolitanism. As a sociological concept, cosmopolitanism refers to a set of "subjective attitudes, outlooks and practices" broadly characterized as “disposition of openness towards others, people, things and experiences whose origin is non local” (Skrbis and Woodward 1). Clearly cosmopolitan attitudes do not have to be geographically located, but frequently the city is promoted as the site of these values, with the suburbs, apparently, forever looking inward.In the realm of marketing, appeals to the imagination are ubiquitous, but discursive practices can become embedded in everyday life. Despite the growth of urbanism, the increasing take up of metropolitan life and the enduring disdain among some for the suburbs, the hard-held suburban values of peace and privacy have pragmatic implications for the ways in which those values are embedded in people’s expectations of life in the inner city.The exponential growth in apartment living in Brisbane offers different ways of living to the suburban house. For a sub-tropical city where "life on the verandah" is a significant feature of the Queenslander house with its front and exterior verandahs, in the suburbs, a reasonable degree of privacy is assured. Much of Brisbane’s vernacular and contemporary housing is sensitive to this indoor-outdoor style of living, a distinct feature and appeal of everyday life in many suburbs. When "life on the verandah" is adapted to inner-city apartment buildings, expectations that indoor-outdoor living can be maintained in the same way can be problematic. In the inner city, life on the verandah may challenge expectations about privacy, noise and visual elements. While the Brisbane City Plan 2000 attempts to deal with privacy issues by mandating privacy screenings on verandahs, and the side screening of windows to prevent overlooking neighbours, there is ample evidence that attitudinal change is difficult. The exchange of a suburban lifestyle for an urban one, with the exposure to urbanity’s complexity, potential chaos and noise, can be confronting. In the Urban Renewal area and entertainment precinct of Fortitude Valley, during the late 1990s, several newly arrived residents mounted a vigorous campaign to the Brisbane City Council (BCC) and State government to have noise levels reduced from local nightclubs and bars. Fortitude Valley—the Valley, as it is known locally—had long been Brisbane’s main area for nightclubs, bars and brothels. A small precinct bounded by two major one-way roads, it was the locus of the infamous ABC 4 Corners “Moonlight State” report, which exposed the lines of corruption between politicians, police, and the judiciary of the former Bjelke-Petersen government (1974–1987) and who met in the Valley’s bars and brothels. The Valley was notorious for Brisbanites as the only place in a provincial, suburban town that resembled the seedy side of life associated with big cities. The BCC’s Urban Renewal Task Force and associated developers initially had a tough task convincing people that the area had been transformed. But as more amenity was established, and old buildings were converted to warehouse-style living in the pattern of gentrification the world over, people started moving in to the area from the suburbs and interstate (Felton). One of the resident campaigners against noise had purchased an apartment in the Sun Building, a former newspaper house and in which one of the apartment walls directly abutted the adjoining and popular nightclub, The Press Club. The Valley’s location as a music venue was supported by the BCC, who initially responded to residents’ noise complaints with its “loud and proud” campaign (Valley Metro). The focus of the campaign was to alert people moving into the newly converted apartments in the Valley to the existing use of the neighbourhood by musicians and music clubs. In another iteration of this campaign, the BCC worked with owners of music venues to ensure the area remains a viable music precinct while implementing restrictions on noise levels. Residents who objected to nightclub noise clearly failed to consider the impact of moving into an area that was already well known, even a decade ago, as the city’s premier precinct for music and entertainment venues. Since that time, the Valley has become Australia’s only regulated and promoted music precinct.The shift from suburban to urban living requires people to live in very different ways. Thrust into close proximity with strangers amongst a diverse population, residents can be confronted with a myriad of sensory inputs—to a cacophony of noise, sights, smells (Allon and Anderson). Expectations of order, retreat, and privacy inevitably come into conflict with urbanism’s inherent messiness. The contested nature of urban space is expressed in neighbour disputes, complaints about noise and visual amenity, and sometimes in eruptions of street violence. There is no shortage of examples in the Brisbane’s Urban Renewal areas such as Fortitude Valley, where acts of homophobia, racism, and other less destructive conflicts continue to be a frequent occurrence. While the refashioned discursive Brisbane is re-presented as cool, cultured, and creative, the tensions of urbanism and tests to civility remain in a process of constant negotiation. This is the way the city’s past disrupts and resists its cool new surface.[i] The use of the word mecca in the brochure occurred prior to 11 September 2001.ReferencesAllon, Fiona, and Kay Anderson.
