Evaluating the Impact of an Integrated Urban Design of Transport Infrastructure and Public Space on Human Behavior and Environmental Quality: A Case Study in Beijing
Urban transport infrastructure can result in the physical, psychological and environmental separation of neighborhoods, public spaces and pedestrian networks, leading to negative impacts on citizens’ daily commutes, social activities and the quality of the ecosystem. An integrated design of transport infrastructure and public space is beneficial for mediating these negative impacts. In this paper, we propose an integrated methodology, which combines urban design, computational scenario evaluation and decision-making processes, based on a conceptual model of human and ecological needs-driven planning. To evaluate the impacts of the road network and public space design on individual outdoor activities, travel behavior and air pollution, an agent-based model is demonstrated. This model is then applied to a case study in Beijing, leading to hourly traffic volume maps and car-related air pollution heat maps of a baseline road network-public space design
Urban and river flooding: Comparison of flood risk management approaches in the UK and China and an assessment of future knowledge needs
Increased urbanisation, economic growth, and long-term climate variability have made both the UK and China more susceptible to urban and river flooding, putting people and property at increased risk. This paper presents a review of the current flooding challenges that are affecting the UK and China and the actions that each country is undertaking to tackle these problems. Particular emphases in this paper are laid on (1) learning from previous flooding events in the UK and China, and (2) which management methodologies are commonly used to reduce flood risk. The paper concludes with a strategic research plan suggested by the authors, together with proposed ways to overcome identified knowledge gaps in flood management. Recommendations briefly comprise the engagement of all stakeholders to ensure a proactive approach to land use planning, early warning systems, and water-sensitive urban design or redesign through more effective policy, multi-level flood models, and data driven models of water quantity and quality
Interprovincial migration, regional development and state policy in China, 1985-2010
Internal migration in China occurs as a result of both market forces and government interventions. This paper investigates how indicators of migration have changed over the past quarter of a century using data from successive censuses, with particular attention given to the roles of regional economic development and national policy and the effects of age and education on spatial patterns of migration. The results show a surge in migration throughout the period, an increasing concentration of migration destinations and an improvement of migration efficiency prior to 2000, but a decreased focusing of migration during the first decade of the twenty-first century. Widening regional disparity has been responsible for a sharp increase of migration from the interior to the coast, and different national economic growth poles emerged as major migration destinations at different stages of economic reforms. The analyses of age- and education-specific migration flows indicate that young adults were more mobile and more sensitive than older cohorts to interregional economic differentials, and that educated migrants were more concentrated than less-educated migrants since knowledge-based industries were more concentrated than labour-intensive industries. Our findings suggest that massive eastward migration induced by unbalanced economic development and relaxed migration restrictions still persisted in the 2000s, and that the State's recent efforts to alleviate regional inequalities were far from achieving equilibrium in the migration system
Ten commandments for the future of ageing research in the UK: a vision for action
Increases in longevity resulting from improvements in health care and living conditions together with a decrease in fertility rates have contributed to a shift towards an aged population profile. For the first time the UK has more people over age 60 than below 16 years of age. The increase in longevity has not been accompanied by an increase in disease-free life expectancy and research into ageing is required to improve the health and quality of life of older people. However, as the House of Lords reported, ageing research in the UK is not adequately structured and a clear vision and plan are urgently required. Hence, with the aim of setting a common vision for action in ageing research in the UK, a 'Spark Workshop' was organised. International experts from different disciplines related to ageing research gathered to share their perspectives and to evaluate the present status of ageing research in the UK. A detailed assessment of potential improvements was conducted and the prospective secondary gains were considered, which were subsequently distilled into a list of 'ten commandments'. We believe that these commandments, if followed, will help to bring about the necessary implementation of an action plan for ageing research in the UK, commensurate with the scale of the challenge, which is to transform the manifold opportunities of increased longevity into actual delivery of a society living not only for longer, but also healthier, wealthier and happier
Coresidency, ethnicity, and happiness of China’s rural elders
As China moves into the ranks of aged societies, coresidency of elders with their adult children has become an increasingly important policy concern. This article utilizes data from the 2000 Population Census of China and the 2011 Chinese Household Ethnicity Survey (CHES) to analyze coresidency patterns of rural elders in seven Chinese provinces with high concentrations of ethnic minority populations. We also explore one consequence of coresidency, reported happiness. We find that socioeconomic variables matter in the determination of coresidency in China in ways that are very similar to their roles in other countries. However, changes between 2000 and 2011 in the effects of age and widowhood show that coresidency decisions among rural elders provinces are transitioning from child-centric to parent-centric. Our analysis also reveals the large role cultural norms play in determining coresidency, as evidenced by differences across ethnic groups. The CHES data allow us to compare coresidency across ethnicity with respect to both individual and regional degrees of assimilation versus isolation. Elders who do not speak Mandarin have higher rates of coresidency than those who do. Additionally, those who live in counties with low rates of intermarriage and intergroup friendships are also more likely to coreside. In exploring the determinants of happiness, we find again that socioeconomic and demographic conditions matter, as does ethnicity. Controlling all else, coresidency increases the happiness of the elderly by about 28 percent. Moreover, the unobserved characteristics that drive coresidency are highly detrimental to the happiness of the elderly
