We have developed a procedure that characterizes the land use pattern of an urban system using: (a) Spatial entropy that measures the extent of spread of residential, business and industrial sectors; and (b) Index of dissimilarity that quantifies the degree of mixing in space of different sectors. The approach is illustrated by using the land use zoning maps of the city state of Singapore and a selection of North American cities. We show that a common feature of most cities is for the industrial areas to be highly clustered while at the same time segregated from the residential or business districts. We also demonstrate that the combination of entropy of residential and dissimilarity index between residential and business areas provides a quantitative and potentially useful means of differentiating the land use pattern of different cities.

As a result of the new economic policy, fourteen Economic and Technological Development Zones (ETDZs) were established in twelve coastal cities between 1984 and 1988. The first ETDZs were Dalian, Yantai, Qingdao, Lianyungang, Nantong, Minhang (Shanghai), Hongqiao (Shanghai), Caohejing (Shanghai), Ningbo, Fuzhou, Guangzhou and Zhanjiang. Unlike Special Economic Zone (SEZ), an ETDZ is located in the suburban area of a major city. Special policies are adopted within the ETDZ. An administrative committee, normally selected by the local government, oversees economic and social management in the zones on behalf of the local government. The category ‘SEZ’ covers a broad range of more specific zone types, including Free Trade Zones (FTZ), Export Processing Zones (EPZ), Free Zones (FZ), Industrial Estates (IE), Free Ports, Urban Enterprise Zones and others. The second wave of expansion of ETDZs was led by the establishment of Pudong New District in Shanghai in 1990. This decision was aimed at elevating the status of Shanghai, making it the “Dragon Head” of the Yangtze River Delta Region, which comprises of Shanghai and parts of Jiangsu and Zhejiang. Prior to the establishment of this new district, the Pearl River Delta Region – comprising nine cities in Guangdong – was the forerunner of China’s open door policy. However, unlike Guangdong, which lies at the south-eastern coast of China, Shanghai’s economic development will have more impact on China’s vast hinterland. Between 1992 and 1993, a total of eighteen state-level ETDZs were established – Yingkou, Changchun, Shenyang, Harbin, Weihai, Kunshan, Hangzhou, Xiaoshan, Wenzhou, Rongqiao, Dongshan, Guangzhou Nansha, Huizhou Daya Bay, Wuhu, Wuhan, Chongqing, Beijing and Urumchi. Two special projects were added later. Founded in 1993, the Ningbo Daxie Development Zone is an investment by China International Trust and Investment Corporation (CITIC), and comes under its management. The other special project is the Suzhou Industrial Park, which was founded in 1994, and is a joint cooperation between the governments of China and Singapore. After 2000, in an effort to fuel the development of the Central and Western regions, the central government also endorsed the establishment of a further eleven national ETDZs in inland regions. Up till now, China has a total of fifty-four state-level ETDZs – thirty-two in coastal regions, and twenty-two in the hinterland. The region of Hong Kong has a role and status of innovation. The planners in this unique part of East Asia expect that some new concepts can help the former British colony to embrace a new economic model: a model in which design, marketing and branding play the crucial role in economy.

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 thesis examines and explains multinational employers' experiences of localized shortages of skilled process workers in Suzhou Industrial Park (SIP), China. It explains three challenges facing SIP employers in accessing sufficient skilled process workers and their responses within HRM to such challenges. These three challenges are employers' experiences with vocational education and training (VET) deficiencies in students' skill development, employers' experiences of poaching of skilled process workers by other companies, and employers' experiences of provision of workplace training for skilled process workers in their own companies. In response to these challenges, SIP employers have adopted various HRM measures that include differing combination of recruitment and selection, employee retention, training and development, and employment relations management. These policies and practices represent the different ways that SIP employers have attempted to meet the challenges of localized skill shortages in the context of their own business strategies.

Coarse typological studies on urban program and density defined by various urban energy conversion technologies in Singapore.

Compared to the beginning of the Twentieth Century, the urban area is expected to triple by 2030. The future urban energy performance is substantially influenced by how the urban area is planned, designed, and built. New energy technologies have enabled new possibilities of the urban form. For example, a district cooling system can free the building rooftops for more architectural design options, like an infinity pool or a sky garden. Vice versa, to maximize the energy performance, some new energy technologies enforce some specific requirements on the urban forms, like the urban form and density. We apply a Mixed Integer Linear Programming (MILP) formulation to identify the optimal allocation of energy demand density and energy systems (e.g. district cooling network) subject to resource availability and energy (or environmental) performance targets (e.g. renewable share). The optimized energy demand density can be translated into urban program combinations and density ranges and gradients. To build the model, we survey the prevailing energy conversion technologies and their costs. Based on the local standards of Singapore, we derive the energy profiles and demand densities of buildings with different programs. We adopt a real case study in Singapore to test the target energy technologies. Adjacent to the existing central business district, the site, currently a container terminal, has an area around 1,000 hectares. Upon the relocation of the terminal in 10 years, the energy technologies, the density, and the program of the site have a variety of possibilities. This paper builds a series of coarse urban typologies in terms of urban program and density when adopting different urban energy conversion technologies in Singapore. Furthermore, the general density and the density gradient may vary when the size of these energy infrastructures alters. In an integrated urban design process involving energy considerations, the urban designer can refer these urban typologies for rules on the general density, the density gradient, and the urban program combination based on the selected energy technologies. On the other way, these urban typologies can also help on the selection of energy technologies to accommodate the target urban density and program.
