This study examines the frequency of consanguineous marriage and the coefficient of inbreeding in the United Arab Emirates (UAE). The study was conducted in Al Ain and Dubai cities between October 1994 and March 1995. A sample of 2033 married UAE females aged 15 years and over participated. The degree of consanguinity between each female and her spouse, and the degree of consanguinity between their parents were recorded. The rate of consanguinity in the present generation was high (50·5%) with a coefficient of inbreeding of 0·0222. The commonest type of consanguineous marriage was between first cousins (26·2%). Double first cousin marriages were common (3·5%) compared to other populations. The consanguinity rate in the UAE has increased from 39% to 50·5% in one generation. The level of consanguinity was higher in Al Ain (54·2%) than in Dubai (40%).

Many cities in the world define themselves as ‘smart.' Is this term appropriate for cities in the emergent Gulf region? This article investigates seven Gulf cities (Kuwait City, Manama, Doha, Abu Dhabi, Dubai, Sharjah, and Muscat) that have once grown rich due to large reserves of oil and gas. Now, with the threat of ending resources, governments focus on the development towards a knowledge society. The authors analyzed the cities in terms of their ‘smartness' or ‘informativeness' by a quantitative survey and by in-depth qualitative interviews (N = 34). Especially Doha in Qatar is well on its way towards an informational city, but also Dubai and Sharjah (both in the United Arab Emirates) make good scores.

<p><strong>Abstract.</strong> Assessing and analyzing the spatial distribution of earthquake events aids in identifying the presence of clustering and reveals hot and cold spots across the study area. Combining the spatial analysis of earthquake events with other geographical and geophysical parameters leads to more understanding of the vulnerability of critical infrastructure and the demographics of the affected population. This study will use Geographical Information Systems (GIS) to examine the spatiotemporal occurrence of earthquake events throughout the Arabian plate and their effect on the United Arab Emirates (UAE). Spatial pattern analysis techniques, including Moran I and Getis–Ord Gi*, were applied to 115 years of earthquakes (1900&ndash;2015) that have occurred throughout the Arabian plate. The directional distribution (standard deviational ellipse) of earthquake magnitudes was analyzed to determine the spatial characteristics and the directional tendency of the earthquakes throughout the Arabian plate. Afterword, geophysical parameters of UAE, specifically Peak Ground Acceleration (PGA), fault line distance, slope, soil type, and geology were ranked, weighted based on its contribution and combined using an Analytic Hierarchy Process (AHP) to identify and locate seismic hazard zones. The resulted Seismic Hazard Zonation Map (SHZM) was classified to five hazard zones ranging from very high to very low. It has been found that Fujairah city sited in the “very High” zone, Sharjah and Dubai cities located from “High” to moderate zones while Abu Dhabi city stands relatively far from seismic hot spots and major faults and placed in the low seismic hazard zone. The results of this study could help improve urban planning and emergency mitigation strategies in UAE.</p>

Texto completo da fonteResumo:
The article examines the effects of cultural diversity on social cohesion in the United Arab Emirates (UAE). The UAE is an oil-rich country established in 1971 as a federation of seven Emirates. It is a small state with a population of ten million; the citizens account only for 10% of the population. Oil wealth enables the country to achieve advanced levels of human, social and economic development. Recently, the UAE has experienced a massive social change; modernization processes have been impended on highest levels. However, due to the historical demographic structure of the local population, the UAE always depended on external labor forces. Skilled and unskilled male workers immigrate from neighboring countries; as a result, the population structure has changed. After the world economic depression in 2008, the UAE experienced a dramatic increase in the number of population. Professional workers from all over the world flowed to the country, and Dubai became a major center for the regional trade market; today, its free zones are considered the best technical base for service and logistic businesses. Today, more than 200 nationalities live in the country, and the majority of them are migrant male workers. This instable and unbalanced demographic structure created cultural domination - international cultures dominate the local one. The demographic imbalance between citizens and foreigners resulted in a kind of disharmony. Due to their feeling of being a minority, the Emiratis move from the old cities to the suburban areas, which creates many social tensions. All these circumstances affected social cohesion, communal harmony and the direct social interaction of cultural groups. To illustrate the tensions and discomforts in the UAE, the author presents the results of face-to-face interviews and a group discussion - as a critical analysis by those in the center of change.

Texto completo da fonteResumo:
This article analyses the case of Dubai’s smart city from a public policy perspective and demonstrates how critical it is to rely on the use of the public-private partnership (PPP) model. Effective use of this model can guarantee the building of a smart city that could potentially fulfill the vision of the political leadership in Dubai and serve as a catalyst and blueprint for other Gulf states that wish to follow Dubai’s example. This article argues that Dubai’s smart city project enjoys significant political support and has ambitious plans for sustainable growth, and that the government has invested heavily in developing the necessary institutional, legal/regulatory, and supervisory frameworks that are essential foundations for the success of any PPP project. The article also points to some important insights that the Dubai government can learn from the international experience with the delivery of smart cities through PPPs.

Texto completo da fonteResumo:
In the last years, the world has jumped rapidly towards more urbanisation, and for the first time in the history in 2008 urban population exceeded the rural population. By 2050, it is expected that two-thirds of the world population will live in urban areas. As a result of this rapid urbanisation worldwide, Sustainable Neighbourhoods SN emerged as a significant formation of cities that help in achieving sustainable development. The 2030 Agenda for Sustainable Development included this sustainability aim through the Sustainable Development Goal 11. This goal aims to “make cities and human settlements inclusive, safe, resilient and sustainable.”The Sustainable City in Dubai is located in the United Arab Emirates, the development and construction started in 2014, and 95% of the site was completed in mid of 2016. The development of the Sustainable City shows that the occupation residents will have many incentives to buy a villa and live in the city such as free rooftop solar systems, open landscaped gardens, free Green Star rated home appliances, zero net maintenance fees, and zero net service charges. Additionally,
the sustainable city in Dubai is an educational hub for sustainable design. It sponsored many students through its agreements with different universities and research labs. This research aims to understand the case of the sustainable city in Dubai as an Example of SN in the Arab world. The research will start with a literature review that identifies all related terminologies to SN, besides a comprehensive analysis of some fundamental principles of SN design. A case study analysis will be done including; site visit, and applying one of the principles of SN on the sustainable city in Dubai to understand and explore the sustainability principles in it.

The aim of this study was to examine consumers’ opinions toward adopting electric vehicles (EVs) for light-duty transport in the United Arab Emirates (UAE) from the functional value (i.e., the utility or benefit attained by consumers from the functions or tangible features associated with EVs) and symbolic value (i.e., the social meaning that consumers associate with EVs) perspectives. The primary research question was as follows: To what extent do functional and symbolic values affect consumers’ opinions toward adopting EVs in the UAE? The objectives were to determine if relationships exist between gender, age, and residency and the functional and symbolic values of consumers’ opinions toward adopting EVs. A survey of 5459 people was conducted in 14 cities across the seven emirates (Abu Dhabi, Ajman, Dubai, Fujairah, Ras Al Khaimah, Sharjah, and Umm Al Quwain) to test the relationship. The results revealed that females, respondents aged 20–29, and residents living in Abu Dhabi City found more appealing functional and symbolic values regarding EVs.

Blockchain technology is an innovative technology with the potential of transforming cities by augmenting the building of resilient societies and enabling the emergence of more transparent and accountable governments. To understand the capabilities of blockchain, as well as its impact on the public sector, this study conducted a review of blockchain technology and its implementations by various governments around the globe. E-government evolution is analyzed, based on empirical evidence from a Dubai government entity in the United Arab Emirates (UAE), which has utilized blockchain technology for developing end-user services, relevant to the public sector. Benefits achieved and challenges to overcome in such blockchain-based pilot deployments are discussed. The findings of this study offer new insights for practitioners involved in bringing in innovations for the benefit of society, using blockchain technology. Furthermore, it provides insights into policy actions to be developed to address the future challenges and to improve already existing e-government policies. The results of this research will benefit all blockchain-based pilot deployments by providing guidance and knowledge on this immature yet developing technology.

Texto completo da fonteResumo:
In 2022, the increased utilization of electric vehicles (EVs) curtailed global carbon dioxide emissions by 13 gigatons. While EV ownership has been on the rise in the United Arab Emirates (UAE), accounting for approximately 1.3% of passenger car vehicles in 2022, it has not yet attained a level of economic feasibility compared to petroleum vehicles. The authors examined consumers’ opinions in the UAE toward adopting EVs for light-duty transport from the economic and geographic perspectives. The main research question was the following: to what extent do economic and geographic factors affect consumers’ opinions toward adopting EVs in the UAE? The objectives were to determine if a relationship exists between economic factors, such as saving money on petroleum, the cost of car maintenance, the cost of purchase, and income level, and geographic factors, including 14 cities across the seven Emirates that affect consumers’ opinions toward adopting EVs. We designed a survey that was distributed to a sample of 5459 respondents to examine this relationship. Descriptive and inferential statistics as well as PyData analytical techniques complemented by the application of data visualization tools such as Seaborn, Plotly, and Matplotlib were employed to examine the dataset. The findings demonstrated that respondents across all income levels have a positive outlook regarding the appeal of EVs for saving money on petroleum, while their interest in saving money on car maintenance and the initial cost of purchase became more pronounced in the higher income levels. Moreover, there were variations in preferences in highly populated Emirates (e.g., Dubai and Abu Dhabi) compared to Emirates with lower populations (e.g., Ras Al Khaimah and Umm al Quwain), confirming that much more emphasis is required to promote EVs in rural areas. When comparing multiple income groups to determine the impact of different factors, the ANOVA confirmed the prevailing patterns evident in the associations.

Texto completo da fonteResumo:
The article aims at substantiating the theoretical and methodological foundations for creating a unified statistical indicators system and statistical analysis of the water resources management at the city level. The advantages of using standardized indicators in the field of sanitation and water supply at the city level are identified and characterized in accordance with ISO 37120: 2014 «Sustainable cities and communities – indicators of urban services and quality of life». Both the main and auxiliary indicators of urban services and quality of life on «Water and sanitary conditions» and «Sewage» topics are systematized as for their formulas, application features and data sources. It is established that, according to the Water Risk Filter, Ukraine can be divided into four regions depending on the water risk, namely, low, moderately medium, medium, and high water risk levels. Based on these data, such cities from the Global Register of Cities developed by the World Council on City Data (WCCD) were selected: Amsterdam (Netherlands), Barcelona (Spain), Dubai (United Arab Emirates), Guadalajara (Mexico). Their indicators in the field of sanitation and water supply were analyzed. It is established that these cities are characterized by a high level of water supply and sewerage services, as well as a fairly high level of the access to high-quality sanitary and hygienic conditions. The situation with quality indicators of water management is worse. For example, advanced waste treatment is only carried out in Dubai. In Guadalajara, 21% of urban wastewater is not treated at all. It is established that in general, Dubai is the leader in the quality of water supply and sanitation services, while Guadalajara is the outsider city, showing the lowest quality levels of most of the studied indicators. The national system of indicators is suggested to be expanded by including such an indicator as «Average annual duration of water supply outages per 1 household»

Abstract In the last half-century, the world has witnessed a fast-paced technological development where cities have been changing tremendously in terms of infrastructure, public health, and quality of life. Looking into the Middle East and specifically in the Gulf states, the rapid urban growth started in the late 20th century has made the status of heritage structures more vulnerable. Cultural heritage in general and modern architectural heritage in particular, are facing extreme danger, which in turn leads to the loss of cultural identity and memory. The paper investigates the modern architectural heritage of the United Arab Emirates (UAE), taking Dubai as a case study. Due to the constant urban and architectural growth that Dubai has been witnessing since the 1950s, its 20th-century heritage has been put in extreme danger of neglect, or extreme physical alterations and, in many cases, demolishment. The UAE governmental bodies have started launching initiatives for the study and preservation of the modern architectural heritage, beginning with the Dubai Municipality’s initiative in 2017, and continuing on a wider scope with the UAE’s Ministry of Culture and Youth initiative in 2019. The purpose of this paper is to contribute to this process by establishing a chronological overview of the various architectural expressions of the modern era in the UAE. In that sense, the paper introduces a set of commercial architectural examples built in Dubai during the period between the 1960s and the 1970s. As well, it identifies and analyses their cultural and architectural characteristics, and assesses their values based on a chronological, morphological, and stylistic overview. The paper provides preliminary results and key findings and discusses possible guidelines and evaluation criteria to identify and evaluate Dubai’s modern built environment to aid their identification and ranking process, as well as promoting the shaping of conservation policies.

Texto completo da fonteResumo:
Many of today´s world wide challenges such as climate change, water supply and transport systems in cities or movements of crowds need spatio-temporal data to be examined in detail. Thus the number of examinations in 3D space dealing with geospatial objects moving in space and time or even changing their shapes in time will rapidly increase in the future. Prominent spatio-temporal applications are subsurface reservoir modeling, water supply after seawater desalination and the development of transport systems in mega cities. All of these applications generate large spatio-temporal data sets. However, the modeling, management and analysis of 3D geo-objects with changing shape and attributes in time still is a challenge for geospatial database architectures. In this article we describe the application of concepts for the modeling, management and analysis of 2.5D and 3D spatial plus 1D temporal objects implemented in DB4GeO, our service-oriented geospatial database architecture. An example application with spatio-temporal data of a landfill, near the city of Osnabrück in Germany demonstrates the usage of the concepts. Finally, an outlook on our future research focusing on new applications with big data analysis in three spatial plus one temporal dimension in the United Arab Emirates, especially the Dubai area, is given.

Texto completo da fonteResumo:
The United Arab Emirates (UAE) has witnessed fast growth in urban development in the past four decades. A plan to build 7270 houses by 2021 has been initiated by the local authorities. Different local sustainability guidelines are being implemented, including the Public Realm Manual in Abu Dhabi. These local guidelines are tailored to consider the hot and arid climate of the UAE as well as the applied materials, the inclusion of greenery, shading devices, etc. Dubai, Abu Dhabi, and Al Ain are cities that have imposed the application of such guidelines. Additionally, the newly developed housing programs match the governmental plan. To understand the effect of these design programs on the outdoor thermal comfort (OTC), further investigations are necessary for each city. The most widely built prototype is detached villas, which result in untreated waste areas without shading or greenery. In the old local neighborhoods, Arabic houses were built next to each other to maximize the shading and to ease pedestrians’ walkability. This study aims to examine the districts where the housing programs are applied and to determine the most effective strategy to minimize the outdoor air temperatures and enhance walkability. The methodology implements the following processes in order: district analyses of the buildings as well as the externally applied materials, microclimate site measurements, ENVI-met (main software used) models of the current and future scenarios, results and recommendations. The strategies have different impacts in both cites due to the microclimate and other conditions.

Texto completo da fonteResumo:
Information and communication technologies (ICT), systems, and people are driving innovative approaches and actions to address issues such as urbanization, demographic change, and carbon footprints of cities. Current research on smart city technologies is typically focused on the areas of technology and applications. As a result, a holistic strategic framework is lacking, as partner organizations often fail to adopt and comply with the necessary interoperability standards, which can undermine the effective and rapid roll-out and transformation of smart city project strategies. This study aims to develop an ICT framework on the determinants of smart city adoption that is developed to help society and policymakers achieve the goals pursued under the smart city initiative, such as maximizing synergies between different ICT infrastructure activities and avoiding large-scale investments without increasing their potential or focusing on short-term solutions without considering long-term needs. Based on data from the literature review and expert interviews, combined with a case study of the United Arab Emirates, this paper identifies the relevant determinants, which are conceptually grouped into seven basic dimensions. For each of these dimensions, relevant sub-dimensions are specified. The framework was developed and validated through three methods: interviews with experts, a desktop study of 62 smart cities, and finally a case study of the Salik system in Dubai based on the concept of the framework. By identifying key adoption determinants, the framework provides a useful analytical perspective for policymakers and researchers involved in the strategic feasibility roll-out and transformation of smart cities.

Texto completo da fonteResumo:
The impact that climate change and urbanization are having on the thermal-energy balance of the built environment is a major environmental concern today. Urban heat island (UHI) is another phenomenon that can raise the temperature in cities. This study aims to examine the UHI magnitude and its association with the main meteorological parameters (i.e., temperature, wind speed, and wind direction) in Dubai, United Arab Emirates. Five years of hourly weather data (2014–2018) obtained from weather stations located in an urban, suburban, and rural area, were post-processed by means of a clustering technique. Six clusters characterized by different ranges of wind directions were analyzed. The analysis reveals that UHI is affected by the synoptic weather conditions (i.e., sea breeze and hot air coming from the desert) and is larger at night. In the urban area, air temperature and night-time UHI intensity, averaged on the five year period, are 1.3 °C and 3.3 °C higher with respect to the rural area, respectively, and the UHI and air temperature are independent of each other only when the wind comes from the desert. A negative and inverse correlation was found between the UHI and wind speed for all the wind directions, except for the northern wind where no correlation was observed. In the suburban area, the UHI and both temperatures and wind speed ranged between the strong and a weak negative correlation considering all the wind directions, while a strong negative correlation was observed in the rural area. This paper concludes that UHI intensity is strongly associated with local climatic parameters and to the changes in wind direction.

Building construction in the UAE is a growing industry. While Abu Dhabi and Dubai have a majority of mid-rise and high-rise buildings, AL Ain has mostly low-rise and mid-rise buildings. Additionally, the construction industry in Al Ain has seen an increase in the recent years. The aim of this study is to design a wellness center with a parametric roof in the challenging topography of Jebel Hafeet Mountain in AL Ain. The building must be socially and environmentally sustainable and must align with the local culture. The methodology used includes the following steps: performing an analysis of the selected site and climate; building the design on challenging topography; creating a parametric roof design; conducting an energy and radiation analysis. Wellness is the act of practicing healthy habits to attain better physical and mental health outcomes. The center will be for females only to provide privacy and to achieve social sustainability (based on the local culture). It will be in Al Ain (Jabel Hafeet Mountain) because unlike the other cities in the UAE, Al Ain does not contain any wellness centers. The design of the parametric roof aims to adapt to the mountain and decrease solar radiation on the roof. Both of the above aim to bring innovation to the city, country, and region for the purpose of building a sustainable design that is adapted to the local culture and environment. The results show a significant energy and solar radiation after the use of such structure. These findings are relevant to local authorities and the private construction industry.

Abstract. Aerosol particles play an important role in the microphysics of clouds and hence in their likelihood to precipitate. In the changing climate already-dry areas such as the United Arab Emirates (UAE) are predicted to become even drier. Comprehensive observations of the daily and seasonal variation in aerosol particle properties in such locations are required, reducing the uncertainty in such predictions. We analyse observations from a 1-year measurement campaign at a background location in the United Arab Emirates to investigate the properties of aerosol particles in this region, study the impact of boundary layer mixing on background aerosol particle properties measured at the surface, and study the temporal evolution of the aerosol particle cloud formation potential in the region. We used in situ aerosol particle measurements to characterise the aerosol particle composition, size, number, and cloud condensation nuclei (CCN) properties; in situ SO2 measurements as an anthropogenic signature; and a long-range scanning Doppler lidar to provide vertical profiles of the horizontal wind and turbulent properties to monitor the evolution of the boundary layer. Anthropogenic sulfate dominated the aerosol particle mass composition in this location. There was a clear diurnal cycle in the surface wind direction, which had a strong impact on aerosol particle total number concentration, SO2 concentration, and black carbon mass concentration. Local sources were the predominant source of black carbon as concentrations clearly depended on the presence of turbulent mixing, with much higher values during calm nights. The measured concentrations of SO2, instead, were highly dependent on the surface wind direction as well as on the depth of the boundary layer when entrainment from the advected elevated layers occurred. The wind direction at the surface or of the elevated layer suggests that the oil refineries and the cities of Dubai and Abu Dhabi and other coastal conurbations were the remote sources of SO2. We observed new-aerosol-particle formation events almost every day (on 4 d out of 5 on average). Calm nights had the highest CCN number concentrations and lowest κ values and activation fractions. We did not observe any clear dependence of CCN number concentration and κ parameter on the height of the daytime boundary layer, whereas the activation fraction did show a slight increase with increasing boundary layer height due to the change in the shape of the aerosol particle size distribution where the relative portion of larger aerosol particles increased with increasing boundary layer height. We believe that this indicates that size is more important than chemistry for aerosol particle CCN activation at this site. The combination of instrumentation used in this campaign enabled us to identify periods when anthropogenic pollution from remote sources that had been transported in elevated layers was present and had been mixed down to the surface in the growing boundary layer.

Abstract. The United Arab Emirates (UAE), a dryland country, has since its independence, emphasized on giant greening projects. Monitoring the trend of greening progress in the UAE has gained importance for environmental management and carbon footprint monitoring. Hence, this study created and analysed a time-series (TS) vegetation map to track and analyse vegetation dynamics over an extended period of fifty years. Study area included three selected desert cities of the UAE, Abu Dhabi (AD) capital city, Dubai city and Al Ain city. Random Forest algorithm was applied on Landsat multi-temporal images from 1972 until 2021 for classifying and monitoring the vegetation dynamics and change trajectories. Four vegetation subclasses (coastal/wetland vegetation, urban vegetation, farms/crop fields, and natural/artificial forests), were assessed then grouped and mapped as one vegetation class. With the adopted approach, we achieved overall classification accuracy ranging from 86% to 94%, with kappa coefficients ranging from 0.7200 to 0.8800. Current study showed that the vegetation cover extent in the UAE was at a constant growth for the past five decades from only 1,231.1 ha in 1972 to 23,176.46 ha in 2021, 19 times folds. Furthermore, it showed that desert cities tend to increase their vegetation cover while continuing their steady urban growth. The other drivers found include demographic increase and governmental policies (granting farms to locals and environmental protection laws). Finally, the approach implemented in this research can effectively and reliably be used in other urban centres for future monitoring and management of the vegetation cover status in the country.

Purpose – Despite the rising significance of the Arabian Gulf on the global corporate landscape, research is lacking in the area of organizational crisis communication. The purpose of this paper is to present a preliminary contribution to this gap in the form of an initial investigation of the conceptualization of crisis among female Emirati nationals in Dubai. Design/methodology/approach – With reference to Pearson and Clair’s (1998) list of organizational crises, the authors designed a survey to elicit perceptions of crises, their severity, and their likelihood of occurring in the United Arab Emirates; the authors administered this survey to 105 female Emirati respondents. Given the heavy delineation of gender roles that exists in the region, the authors limited this initial study to a single gender, women. The authors discuss the crises respondents identified as most severe and most likely to occur in the country in terms of culture, Islamic values, and business in Dubai. Findings – Responses indicate that perceptions of crisis differ vastly from those that typically obtain in western countries and that particular religious and cultural factors influence these perceptions. Research limitations/implications – Given the divergence between the construal of crisis in the Gulf and in western contexts, further investigation of how organizational crisis is perceived and responded to in Gulf contexts is warranted to inform corporate communication management in a region whose economic influence is increasingly important. Future research also needs to investigate a broader sample, including male respondents, in order to construct a framework of culture and crisis in the region. Practical implications – As more MNCs are attracted to Dubai, and other Gulf cities, it is imperative that they are well informed of the differing perceptions of, and reactions to, potential crises that may affect them directly or indirectly. Originality/value – The present study is the first the authors know of that assesses how organizational crises are perceived in a Gulf context. It brings to the fore certain particularities that could serve as hypotheses for an innovative research stream. While it is an exploratory study, it highlights salient issues that can be formulated into hypotheses in further research.

At a current world city scale, conurbations interweave complex multimodal systems of logistics, transport, and communications. As this process evolves into a global network of interconnected urban nodes. While diffusing globally, China’s One Belt One Road (OBOR) proposal creates an infrastructural framework for global exchange, analogous to the Ancient TransAsian links of Silk Road and Indian Ocean. Linked spatial dimensions and functional regions have always existed at different scales without any synchronized nomenclature for a grid with exact dimensional measurements. The global surface exists as a topological phenomenon of multi scalar dimensions covered by varied surface phenomena from earth to vegetation with fluid elements alternating in liquidity and flows. increasingly the world cities trend divides more advanced urban regions from less well viably connected territories, governments, industries, and commerce. Thus, the world has been experiencing an unequal distribution of trade and associated transport, logistics and handling facilities. In relation to global trade and transport tends to focus on the post-industrialized West and East and so underplays the role of other parts of the world system, including the MENASA (Middle East–North Africa–South Asia) region. In doing so, scholars discount a variety of spatial, morphological, environmental, historical, and socio-political urban patterns particular to these other regions and cities. This article addresses this oversight by examining the United Arab Emirates coastal conurbation (U.A.E.–CC, including Dubai–Abu Dhabi–Sharjah–Ajman), with its unique global positioning and political and economic conditions. The U.A.E.–CC is explored in relation to theories of the world/global city, the airport city or aerotropolis, and the polycentric urban region (PUR). The article demonstrates the emerging formation and potential of the U.A.E.–CC PUR, a member of a world-city network specializing as a transport hub and tourist destination and a global logistics center.

Purpose Cities from developing countries strive to compete on a global scale and hence try to attract and retain their residents in offering higher liveability. The purpose of this study is to examine the extent to which liveability influences resident’s sense of place and determines residents’ behavioural intentions. Design/methodology/approach A survey was carried out to test the hypotheses using a sample of 362 residents from the city of Dubai (United Arab Emirates). Structural equation modelling and the method suggested by Hayes and Preacher (2010) for mediation analysis were used. Findings Findings show that residents’ preferences for different types of liveability attributes (included in seven dimensions) influence their sense of place that in return shapes their behavioural intentions towards their place of residence. Results also reveal the importance of non-economic attributes of the urban environment. Moreover, residents’ sense of place mediates the relationship between liveability and residents’ behavioural intentions. Research limitations/implications Future research could more deeply investigate the social functioning of a place and particularly the role of place identity, as it is recognized to affect residents’ attitudes and behaviours. In addition, further developments may contribute to the ongoing debate on the relationship between liveability and growth. Practical implications From a public policy standpoint, this study suggests that local authorities need to identify a distinct set of economic and non-economic characteristics that will encourage residents to stay longer in the place they live. As such, enhancing liveability represents a critical strategic initiative for cities from developing countries to make them a great place to live. Originality/value Compared to developed countries’ cities, few attempts have been made to investigate the attitudes of residents towards a place and the role of liveability in the context of emerging countries fast-growing urban areas. In addition, findings revealed the importance of place-based meanings, i.e. sense of place, which played a pivotal role in the development of place-protective behaviours.

Texto completo da fonteResumo:
Over the last 50 years the cities in the United Arab Emirates (UAE) developed rapidly. Building stock is very diverse in the country and varies from one city to another. While Dubai has a large stock of skyscrapers, Abu Dhabi has more of a mix of high-rise and mid-rise buildings, and AL Ain—mainly mid-rise and low-rise buildings. The aim of this study is to evaluate the energy consumption of a retrofitted building versus a new building designed based on advanced tools of calculation. The new design is based on sustainability principles of design as well as the advanced parametric design where the analysis considers several parameters. This evaluation is a comparison between the current building, a retrofitted building, and a new design of the same build-up area. This analysis will be conducted considering local sustainability standards such as Estidama and Abu Dhabi Realm Manual. The methodology starts with the building selection process which consists of the selected building as part of a villa compound done in the city of AL Ain. The site measurements are the following step. This file is used for the boundary conditions of the models. The following step involves energy simulations. The models were prepared with several scenarios as per the predefined analysis and run for simulation. Grasshopper throughthrough rhino were the softwares used for energy simulations and applied design. Therefore, energy saving was calculated based on the selected matrix. The results show that the selection of the shape of the building and application of sustainable measures in the early stages of design can save 32% of energy, and a retrofit of the current building would save 9% of the electricity used.

ObjectivesTo assess Arabic-speaking patients’ preference for involvement in decision-making in the United Arab Emirates (UAE) and characterise people who preferred involvement in decision-making.DesignCross-sectional quantitative study. The conduct and reporting of this research complied with Strengthening the Reporting of Observational Studies in Epidemiology guidelines for cross-sectional studies.SettingParticipants were recruited from outpatient clinics of 10 major hospitals in four cities in the UAE: Abu Dhabi, Dubai, Sharjah and Umm al Quwain.ParticipantsAdult patients with at least one chronic disease completed a cross-sectional survey consisting of 37 items in six sections measuring variables that may influence preferred involvement in decision-making. These included health literacy, health status, unanswered questions about care and satisfaction with treatment decisions. Bivariate and multivariate analyses were performed to determine the predictors of patients’ preferred involvement in decision-making.ResultsA total of 516 participants completed the survey. One-in-four participants preferred shared decision-making. Preferred involvement in decision-making was more frequent among women, not married, unemployed, people who rarely/never had unanswered questions and participants with anxiety/depression symptoms. After adjustment, not being married (OR=1.634; 95% CI 1.049 to 2.544) remained as a predictor of preferred involvement in decision-making, while having unanswered questions (OR=0.612; 95% CI 0.393 to 0.954) and problems in self-care were predictors of a preference for paternalistic decision-making (OR=0.423; 95% CI 0.181 to 0.993).ConclusionsContrary to the results from Western countries, this study showed that a majority of Arabic-speaking patients with chronic diseases preferred a paternalistic decision-making model. At the same time, some subgroups of Arabic-speaking people (eg, women, unemployed patients) had a higher preference for participation in decision-making. Physicians’ support and changes in healthcare systems are required to foster Arabic-speaking patients’ involvement in treatment decision-making process.

Abstract Objective The study aims to analyze job satisfaction among registered clinical dentists in the United Arab Emirates (UAE), and also to explore satisfaction with different work environmental factors and relate them to overall job satisfaction. Materials and Methods A survey modified from the American Dental Association version of job satisfaction published in 2013 to 2014, was given to 197 licensed dentists in Dubai and Sharjah cities in the UAE. The questionnaire included four main sections, in addition to the demographic factors questions. All questions were answered using the 5-point Likert scale. The only exception was the comfortability in the working environment which was answered using a 3-point Likert scale. Statistical Analysis Categorical data were presented as frequencies and percentages, and data were analyzed using means and standard deviations. Regression analysis was performed with overall job satisfaction as the dependent variable and seven aspects of satisfaction with work and individual characteristics as the independent variables. An α level of 0.05 was used for tests of statistical significance. Results The overall job satisfaction of dentists working in the UAE is high compared with other countries. Highest satisfaction was related to the relationship with patients, colleagues, and staff. On the other hand, the least satisfaction was linked to the opportunity for part-time work and benefits package. There were no significant differences between male and female participants regarding all work-related factors apart from autonomy. However, private sector dentists had a higher level of satisfaction compared with the public sector in many work-related factors. Conclusion There are various dimensions that collectively influence the level of overall job satisfaction. Difference existing between the levels of job satisfaction among private and public sector dentists and between male and female dentists need to be addressed to increase the level of job satisfaction among UAE dentists and thus improve all dental care system.

Region and culture have been influenced in shaping the past architecture space. It is to examine that vernacular architecture in the modem cities of the United Arab Emirates (UAE). And how this view creates obstacles in the interaction of satisfying historic building forms and techniques. The greatest obstacle is the complex symbolic role that these buildings play in modem nation building. The objective of this study is to analysis the interaction between Tradition and Modernity in contemporary architecture and its relationship to the vernacular and cultural aspects, as evident in the case of the United Arab Emirates. While historic buildings are viewed with homesickness, they are also not deemed suitable for contemporary life and have been isolated in the process of economic and social development, separated from enlivening social activities, historic architecture in the UAE seems designed to survive only as outdoor museum displays.

Texto completo da fonteResumo:
The global record of 1,700 % urban footprint growth in only 38 years made Dubai one of the fastest growing cities in the world. The density of the metropolis population is approximately 762.6 individuals/ km2, and high-rise residential buildings in Dubai have reached 581,166 units (79%) in 2020 and become a common residential type. The objective of this study is to provide basic data for the design of high-rise residential buildings in the future by evaluating the health of the residents of high-rise residential buildings in Dubai. As a methodology, the Todai Health Index, a structured health assessment tool, was used for high-rise residents’ survey. For the analysis, the health evaluation data from residents were used as the dependent variable, and the number of living floors as the architectural characteristic and the indoor temperature and humidity condition as the residential environments were analyzed as the independent variable. The result had shown that residence floor is irrelevant to overall health, changes in the health status compared to those in the previous year, and the occurrence of daily disease health evaluation by the Todai Health Index. It was statistically proven that the thermal environment has a significant correlation with the residence floor, but the effect of the thermal environment on health was not strong. However, the humidity environment has a very strong relationship with the health of residents. The humidity environment has a very close relationship not only with the occurrence of daily diseases of residents but also with the health evaluation analyzed by the Todai Health Index. There is a significant relationship between the humidity environment and both physical and mental health. It was analyzed that a slightly humid condition had a positive effect on health.

Texto completo da fonteResumo:
AbstractThis study investigates the career paths of 33 graduates from Swiss Hospitality Management schools in China and the United Arab Emirates (UAE), exploring the nuances of international credential valuation. It identifies two key factors influencing access to management positions: (1) the degree of internationalization in major cities, which impacts the significance of international versus local skills and (2) individual cosmopolitan capital's role in shaping local career opportunities. The paper introduces a post‐colonial conceptualization of cosmopolitan capital, encompassing institutionalized, embodied and objectified forms, challenging Western‐centric views. By doing so, it reveals how mechanisms of racialization influence the assessment of international qualifications. In Hong Kong and Shanghai, returning Chinese are prospering in corporate head offices by mobilizing both local/national and international capital, challenging the white privilege of Western managers in this sector. Meanwhile, in Dubai and Abu Dhabi, the competition is for a pool of ‘international talent’, even though being perceived as ‘Arab’ or ‘white’ seems to improve career prospects.

Texto completo da fonteResumo:
The United Arab Emirates (UAE) has a long-term policy horizon, the financial capital, and a vision for a sustainable knowledge-based economy. These characteristics uniquely situate it as a potential leader for sea-level rise research. Climate science is already growing, and at the center of the UAE's pivot toward climate research is a burgeoning concern for sea-level rise. Over 85% of the UAE's population and more than 90% of the nation's infrastructure is within a few meters of present-day sea-level. With its low-lying and shallow-sloping geography (about 35 cm per km), this high-value coastline, including the rapidly expanding cities of Dubai and Abu Dhabi, is particularly vulnerable to sea-level rise. Meanwhile, limited regional research and data scarcity create deep uncertainty for sea-level projections. We set out a potential roadmap for the UAE to capitalize on its strengths to create usable and relevant sea-level projections for the region. With a newly established Climate Change Research Network, the UAE government is beginning to draw together universities and research centers for “furthering effective data collection and management, and advancing policy-relevant research on climate impacts and adaptation1.” By consolidating ideas from the science community within the UAE, we identify promoters and barriers to data gathering, information sharing, science-policy communication, and funding access. Our paper proposes pathways forward for the UAE to integrate sea-level science with coastal development and form best practices that can be scaled across climate science and throughout the region.

AbstractVertical urbanization to maximize land use in many cities has led to a shortage of urban spaces that could adequately meet people's needs. In response, CityWalk has emerged as a new urban form to solve this problem by attracting people to go from inside closed buildings to outside walks. Thus, it is promoting health, economy, and tourism. Locally in the United Arab Emirates (UAE), especially in Dubai, a limited number of CityWalks have been developed. Despite the increasing popularity of CityWalks, there has been a gap in research examining their distinct emerging urban typologies and their urban configuration. This study seeks to address this gap by first conceptualizing CityWalk as an emerging urban public space based on the exploration of global and local experiences. Second, the study categorized the morphological configuration of three selected case studies of CityWalks in Dubai using Geographic Information System (GIS) tools. These case studies represent three different developments of CityWalks in three different contexts in the UAE. First, CityWalks within the inner city's urban context are represented by ‘City Walk’ in Al Wasel. Second, CityWalks surrounded by the sea represented by 'The Walk’ in Marsa Dubai. Third, CityWalks developed next to traditional buildings represented by ‘Al Seef’ in Al Hamriya. The findings of the research investigations reveal that the emerging ‘CityWalks’ developments in each of the three different urban contexts in Dubai do not represent a single familiar urban space typology but rather a ‘harmonious’ blend of global and local urban design typologies. In addition, the urban morphological analysis of these three urban developments underscores the distinctive characteristics of each of them in terms of street network, urban form, urban compactness, land use, and shading. This contributes to better understanding of these emerging urban forms and hence pave the way for more research about their socio-economic robustness to ultimately contribute to more successful future designs of ‘CityWalks’ in Dubai and other cities in the region.

Infrastructure projects in the United Arab Emirates (UAE) at federal and local levels have been continuously growing. This includes installation, inspection, repair, and replacement of water mains, sewer, storm water, power, and telecommunication networks. Traditionally, these tasks related to underground utilities involve open trenching construction methods resulting in expensive and disruptive operations, particularly in congested urban areas like Dubai and Abu Dhabi cities. To avoid this serious problem, contractors and local municipalities are using trenchless construction in their infrastructure projects. The development of trenchless methods has gained impetus in the construction industry in UAE due to increasing amounts of investment in underground infrastructures that are new, deteriorating, or under capacity. This paper presents the results of a questionnaire survey of trenchless construction methods used by municipalities and contractors in UAE. The survey provides an indication of current and expected future trends in the application of trenchless construction technologies including types of technologies employed and percentage of projects that employed trenchless technologies. The survey results indicate that trenchless technology is gaining increasing popularity among contractors and municipalities across UAE. The survey results also indicate that trenchless technology is gaining increasing popularity among municipal engineers across UAE. The survey also revealed current and likely future growth in utilizing trenchless construction methods and the average expenditures of municipalities in UAE for new construction and for rehabilitation.

AbstractArid regions can benefit from using native desert plants, which require minimal freshwater and can aid in remediating soil phytotoxic metals (PTMs) from traffic emissions. In this study, we assessed the ability of three native desert plants—Pennisetum divisum, Tetraena qatarensis, and Brassica tournefortii—to accumulate phytotoxic metals (PTMs) in their different plant organs, including leaves, stems, and roots/rhizomes. The PTMs were analyzed in soil and plant samples collected from Dubai, United Arab Emirates (UAE). The results indicated significantly higher levels of PTMs on the soil surface than the subsurface layer. Brassica exhibited the highest concentrations of Fe and Zn, measuring 566.7 and 262.8 mg kg−1, respectively, while Tetraena accumulated the highest concentration of Sr (1676.9 mg kg−1) in their stems. In contrast, Pennisetum recorded the lowest concentration of Sr (21.0 mg kg−1), while Tetraena exhibited the lowest concentrations of Fe and Zn (22.5 and 30.1 mg kg−1) in their leaves. The roots of Pennisetum, Brassica, and Tetraena demonstrated the potential to accumulate Zn from the soil, with concentration factors (CF) of 1.75, 1.09, and 1.09, respectively. Moreover, Brassica exhibited the highest CF for Sr, measuring 2.34. Pennisetum, however, could not translocate PTMs from its rhizomes to other plant organs, as indicated by a translocation factor (TF) of 1. In contrast, Brassica effectively translocated the studied PTMs from its roots to the stem and leaves (except for Sr in the leaves). Furthermore, Pennisetum exclusively absorbed Zn from the soil into its leaves and stems, with an enrichment factor (EF) greater than 1. Brassica showed the ability to uptake the studied PTMs in its stem and leaves (except for Fe), while Tetraena primarily absorbed Sr and Zn into its stems. Based on the CF and TF results, Pennisetum appears to be a suitable species for phytostabilization of both Fe and Zn, while Brassica is well-suited for Sr and Zn polluted soils. Tetraena shows potential for Zn phytoremediation. These findings suggest that these plants are suitable for PTMs phytoextraction. Furthermore, based on the EF results, these plants can efficiently sequester PTMs.

Texto completo da fonteResumo:
AbstractEngineered canals and waterfront developments as a means to revitalize aging riverfront and coastal areas, dominated until the mid-thirties by industrial buildings and warehouses, have been at the forefront of many American and European cities. Urban revitalization is accomplished after prolonged public participation and has succeeded to transform abandoned areas to healthy public spaces, renovating old warehouses and industrial buildings to apartments with water views, and keeping alive the historical memory of a city. In contrast, in the United Arab Emirates (UAE), most of these waterfront developments, such as Al-Qana, a recent project in Abu Dhabi promote forms of modern, spectacular architecture that project a sense of departure from tradition, local culture and architecture. This is also visible in the area around the Dubai canal, which has opted for a modern development on its banks, replacing parts of an existing open park. A project that diverges from such an approach is the two-decades old waterfront project in the city of Sharjah, UAE. Al-Qasba in Sharjah aimed for a more balanced approach, intertwining new architectural forms with hybridized Islamic ornaments. The current article analyzes these three UAE waterfront development projects, focusing on the one in Abu Dhabi. In order to assess the water quality in these engineered canals on the long term we created simulation waterflow models using 2D Finite Element Surface Water Modelling System (FESWMS). Our hydrodynamic modeling results indicate that water velocities in some canals was better than others. Furthermore, on the long-term Al-Qana may require mechanical means in order to maintain healthy waterflow conditions.

Background: People with addiction do not have control over their behavior, actions or usage. Their addiction may reach to a point that it is harmful. Addiction does not only involve the physical aspects such as drugs or alcohol but also includes abstract things, often described as a behavioral addiction. The causes of addiction differ considerably and are seldom fully understood. They are generally caused by varying degrees of physical, mental, circumstantial and emotional factors. Objectives: To study the electronic devise profile among children and adolescent in modern global cities such as Dubai and to study the prevalence and size of the addiction phenomena. Methodology: This study was carried out in Dubai, United Arab Emirates during the Global School Health Survey in 2015. The sample included 7000 students who were randomly selected (multistage stratified random sample) from 10 private schools in Dubai. Data collection was carried out by standard questionnaire developed by the World Health Organization which includes different health domains (addiction, and addiction to electronic devices). Ethical issues were followed up to standards. The questionnaire and consent forms were given to the participants who met the inclusion criteria. An information sheet was attached to the questionnaire explaining the purpose of the study. The students were assured that the confidentiality and privacy of the answers were maintained. No names, phone numbers, and identification are required. Data coding, data entry and data analysis has been conducted by using SPSS 20 software. Results: The present study revealed that 56% of school children aged 13-15 years old spend three hours or more a day using electronic games, and this percentage rises to nearly 63% with the age group 16-17 years. The study showed that children, who excessively use these games might face social, emotional and behavioral problems such as isolation, anxiety and depression. Pointing out that children may complain of psychological pressure, stress or dehydration and burning eye, due to constant staring with bright light across the screens of devices. Most students (68.7%) said they were on social media between one and five hours daily, while 3.3 per cent said they spend less than an hour. 39.8% of students stayed without food or drink for a long time and 50.5 % tried to quit social media last year but failed. 15% of students spend 4-8 hours on social media and 1.6% spend more than 10 hours. When the students were asked about how they feel of the burden on their daily life and social commitments, 60% of them replied that social media decreases their interaction with the outside environment and family time, 55.6% said it interfered with their homework. The study showed that more than one quarter (26.7%) or almost one out of four reach up to more than 6 hours per day and could sometimes reach up to 10 in browsing and interacting with social media. The study reflected that more than 400 children showed the negative symptoms on the use of tablets. It appeared significantly on children who use them for more than two hours a day compared to their counterparts who do not use it at all or use it less than two hours. They have noticed that those who use it less

It appeared significantly on children who use them for more than two hours a day compared to their counterparts who do not use it at all or use it less than two hours. They have noticed that those who use it less have great language, motor and mental skills. Parents do not seem to be paying attention on how technology is taking their kids away from them. Children between the ages of 11 and 17 found out what really is keeping them so busy on all these addictive devices. Around 70% of them are most vulnerable to gaming addiction. They belong to the under-five age group, because parents are preoccupied with them. Conclusion: Electronic addiction among children and adolescents is a rapidly growing phenomena in the City of Dubai. It has a significant impact on the social and professional life and functions of this group, which necessitate intervention at many levels.

The study will conclude with a way to develop institutional structures implementing Solow’s conceptualization of intergeneralization that can collaborate peace and increase funds for quality water throughout the Middle East. The study is a humanitarian approach addressing the issue in the Middle East of many people going without natural resources of quality water. Identify what the commonalities between different sectors were and where synergies lay in terms of governance paths (Tiller etc al, 2021.p.1). Artificial Intelligence, Synthetic Intelligence and computational are investigated in to improve efficiency by implementing indicators for leaks, security and data and able to view in real-time. The study is a quantitative, qualitative, and mixed methods approach that includes an e-mail chain, service partners, auditing, and project scope. Synergy and value are the variables. Artificial Intelligence that can be transcended containment (Capitol Technology, 2022p.1). Machine learning is exploding as an application of narrow AI (Artificial Intelligence), used to comb through vast amounts of data to better develop and market products (Capitol Technology, 2022. P.1). Cultural transparency will be investigated along with how the government manages reluctance and how they build strong relationships. A focus is on building a network of founder’s challenges facing our world today to demonstrate how interconnected we are and how the fates of all people are bound up together (President Biden,2021). The outbreak of a virus overseas can cause profound grief and suffer at home (President Biden, 2021). Energy data will be reported to show key metrics and will be compared to countries in the Middle East and measured in amounts of water consumption and renewable energy. Conflict a continent away can create endangers our security (President Biden,2021). Economic downturns abroad can mean lost jobs and shuttered businesses in towns across the globe (President Biden, 2021). Global climate change worsens hurricanes in the Gulf, floods in the heartland, and wildfires in the West (President Biden,2021). An engineering analysis of options is needed to decide which method is the most cost-effective and the potential locations. Initial potential locations are Oman, Qatar, Emirates, Iraq and Saudi Arabia. Potable water is always supplied through some municipality or other government agency; we envision a public-private partnership for this phase. As a first step, the author is looking to collaborate with a partner to perform a feasibility analysis to determine which method will be the least costly to implement, have the secured payback in terms of selling the potable water, and have the largest long-term profitability and setting a standard. Intended Audience, Leading Corporations, Innovators, Investment Managers, Companies Raising Capitol, Wealth Advisors, Independent Scientists, Research Centers, Universities, Governments, Institutions, Water Dubai Industrial, Independent Sponsors, Islamic Financial Market, Governance Indictors, Businesses in the Arab World, Professors, Deans, Ministries, Authorities, Engineers, Foreign Holdings, The General Reserve, Monetary Agencies, Scholars, and Sovereign Wealth Fund Institutions. The study gives a historical comparison and uses the Ad Hoc theory implementing when necessary. The author is discussing how we can reduce evaporation as this increases the amount of water being produced. There is a more substantial cost with producing water from the air. There is also an abundance of panels that are required. Desalination is not new; it has been around since the ‘70s. The study shows that the Middle East will increase the water supply and have a cost available at .88 percent which comes from desalination plants which is much higher than what households and businesses pay for it (MENA, 2021.p.1). On current plans and projections, Bahrain will be able to increase desalination capacity to meet municipal water demand by 2030, but that will entail heavy financial, economic, and environmental burdens (Mena, 2021). The author searched the Persian Gulf, Talha, Khan, Aquil, Qatar, Saudi Arabia, Isreal, Bahrain, United Arab Emirates, and the counts were 415 companies and 1,860 contacts (Dunn,2021p.1).
