The affordability of owner occupied housing in Beijing

Facilitating home ownership and providing more affordable housing has received considerable attention in urban China. However, it remains a challenge to develop better measurements of affordability due to the income disparity and housing inequality in Beijing. In this study, a new measure of affordability is defined by residual income. Therefore, a minimum required budget for a family to purchase a “standard” unit is deduced by accounting for the basic necessities and financial loans. This paper also discusses the deficiencies of the implemented “Economic Housing Plan” on bridging the housing affordability gap.

The Limits of Decentralisation in Urban Zambia

Against a background of the expansion of decentralisation across sub-Saharan Africa and widespread debates concerning the benefits associated with decentralisation, this article analyses the example of Zambia. The paper highlights the “limits” or constraints affecting the success of decentralisation. From detailed research in Ndola, attention is drawn to several issues surrounding the council’s inadequate human resource base as well as critical funding constraints which impact upon public service delivery.

Public Perceptions of High-rise Building Emergency Evacuation Preparedness

In light of the events of September 11, 2001, a concern in the fire safety community is that the public attitudes toward emergency evacuation procedures and preparedness may have changed and that current assumptions about occupant behavior may no longer be valid. In 2006, a survey of high-rise building occupants was conducted to explore their knowledge of high-rise building safety and emergency evacuation procedures and their attitudes and perceptions about high-rise safety and emergency evacuation procedures. Some 244 residential building occupants in Chicago, New York City and San Francisco and 228 commercial building occupants in Boston, Chicago, Detroit, Houston, Los Angeles, Miami, and Philadelphia were surveyed. The study revealed that the events of September 11, 2001 have heightened occupants concerns about safety in high-rise buildings. Eight in ten commercial building respondents participated in a fire drill in the last year, compared to 18% of residential building respondents. Among both survey respondents, the most frequent top-of-mind suggestion to building management to improve safety was “more fire drills.” Almost all occupants know where the fire exits are. And, keeping with conventional wisdom, most occupants believe using elevators is unsafe during a fire, however, 28% also believe that going to the roof is a possible alternative to using the stairs. These findings support the need for continued public education about emergency evacuations procedures in high-rise buildings.

North–South transfers vs biodiversity conservation: a trade differential game

Trade relationships connect developed and developing countries. The former produces a consumption good, using labor, capital, and an intermediate “natural” good which is produced in the developing countries using labor and natural species. A finite horizon differential game is settled out. The North decides about either the saving rate or the portion of its disposable income to transfer to the South or both variables jointly. The South selects the range of species used in the production of the intermediate “natural” good required in the North’s productive process. This is a measure of biodiversity loss. The aim of the paper is to study how transfers from North to South affect capital growth and biodiversity conservation.

Are there really high-tech clusters? The geographic concentration of German manufacturing industries and its determinants

The agglomeration of industries has recently received much interest both in empirical and theoretical works time. Especially in Germany politicians became inspired by the notion of high-technology industry clusters, and regional policy has seen a wave of initiatives aiming at the formation of such clusters. This paper explores in a systematic way the geographic concentration of German manufacturing industries and relates it to industry characteristics and agglomeration forces proposed by theory. The main finding is that there is no general relationship between agglomeration and high-technology related business which suggests that hope put in the fast and effective development of “high-tech” clusters might see some disappointments in the future.

Performing the Primitive in the Postcolony: Nyoni’s Kraal in Cape Town

The production of particular spaces for tourist consumption of the “exotic” other involves the performance of particular conceptualizations of people and places that recreates theatrical versions of the primitive. Through analysis of one such space—Nyoni’s Kraal in Cape Town—we contend that both hosts and visitors are complicit in the construction of these spaces and imaginaries. To this end, practices of social and spatial policing as well as performativity and representations of cultural constructs of an “authentic Africa” are deployed in the projection of a specific form of constructed, “benign” multiculturalism. We contend that such practices reproduce a mythical idyll of Africa for consumption that recreates—rather than questions—colonial power structures, and therefore remain imbued with the inequitable and uncertain outcomes of modernity.

Testing the credit view with pooled data: dynamic links among state bank health, investment-oriented bank loans, and economic performance

This paper focuses on the “credit view” theory at the state level, which suggests that state-level banking sector health influences state-level real economic performance. Specifically, we extend typical analysis of the credit view theory, applying relevant state-level economic variables to consider whether the health of a state’s banking system affects capital investment loans and, in turn, whether growth of these loans affects a state’s economic performance. We develop a two-equation state-level model, use more refined measures of capital investment loans, and apply advanced dynamic pooled estimators to our panel of state data for the 1984–1993 period. Regression results support dynamic links among state bank health, state investment-oriented bank loans, and state economic performance, thus supporting existence of a state-level credit channel effect.

Job search success and employability in local labor markets

This paper considers the relationship between an unemployed person’s employability and job search success. Using a broad employability framework (covering individual, personal and external demand, and other factors) the paper considers a range of demand and supply factors, that were generally identified in applied and theoretical literature, that influence success in getting employment. The model is then used to consider the competing efficient metropolitan labor market and the local labor demand hypotheses in terms of the importance for this sample of skills mismatch and spatial mismatch. The findings suggest that professional qualifications, “soft” verbal skills and using speculative applications to employers were significantly associated with job search success. Length of unemployment, age, and having last worked in a manual occupation were negatively associated with job success, the latter decreasing the odds of getting a job to around thirty percent, suggesting difficulties in occupational “switching” for many job seekers. Higher academic qualifications were also significantly negative, as were those claiming that promotion chances will influence their reservation wage. The geographic accessibility to local jobs was significantly and positively associated with job search success. The results suggest that a range of employability factors and both skills mismatch and spatial mismatch are important in explaining job search success. The degree of “skills” or “spatial” mismatch in a local labor market will be contingent upon the characteristics of the local economy, employers, job seekers and the jobs being considered.

Market access and regional disparities

New economic geography (NEG) has reached a theoretical consolidation while related empirical tests are still scarce. The present paper aims at providing some evidence on the validity of forces emphasized by NEG. The analysis starts from the nominal wage equation derived from the Krugman “core–periphery model” and focuses on one of the main propositions of NEG that access advantages raise factor prices. The paper investigates the significance of market access for regional wages and the geographic extent of demand linkages for a cross section of European regions, also taking into account the effects of national borders. The regression analysis covers the period between 1985 and 2000. The results are consistent with the implication of NEG that demand linkages affect the geographic distribution of economic activities, confirming the basic findings of previous analyses. However, regarding the spatial extent of demand linkages, our results differ significantly from previous findings that point to highly localised effects.

Inter-generational Occupational Mobility Amongst Blacks in the Mitchell’s Plain Magisterial District, Cape Town: Evidence from the Khayelitsha/Mitchell’s Plain Survey

This study examines inter-generational occupational class mobility amongst blacks (Africans and coloureds) in the Mitchell’s Plain Magisterial District in Cape Town, South Africa. The results of the Khayelitsha/Mitchell’s Plain Survey conducted in 2000 serve as the main source of data. We show that middle-class occupational origins do not necessarily guarantee the transmission of advantage from one generation to the next. The findings revealed that there is a churning effect at work with respondents experiencing upward occupational class mobility due to the changing occupational structure, which at the same time is counteracted by considerable downward occupational class mobility. This result is partly due to (1) the particular class structure of the Mitchell’s Plain Magisterial District, which excludes many middle-class black areas and therefore has a more working-class character and (2) the precarious character of the black middle class, which is concentrated in low-paid nursing and teaching occupations.

Indicators of Small Town Tourism Development Potential: The Case of Fouriesburg, South Africa

As small towns experience economic and social restructuring, many are pursuing tourism opportunities as one component of a more diversified local economic strategy. This paper is interested in the small town of Fouriesburg in South Africa's Free State. While the town was once a thriving service center for a surrounding rural agricultural region, this traditional economy has faded. Given that the nearby town of Clarens has developed a substantial tourism economy, we pose the question of whether there already exist indicators that Fouriesburg may be poised for a similar change. These indicators include location within the urban field, timing within the tourist area life cycle model, differentials/opportunities in property values, and the role of real estate agents as “gatekeepers” in directing investments. The findings suggest that, while Fouriesburg has potential for developing a tourism-oriented economy, many of the important policy and planning supports needed to assist with diversification are not yet in place.

An Experimental Determination of a Real Fire Performance of a Non-Load Bearing Glass Wall Assembly

A glass wall assembly was exposed to an intense real-scale compartment fire. The wall assembly consisted of four glass sections, two of which were fitted with tempered double-pane glass and the other two sections were fitted with tempered single-pane glass. At each glass section, temperatures were measured at the exposed face and the unexposed face. Total heat flux gauges were used to measure both the temporal variation of the energy incident on the glass wall and the transmitted energy rate detected through two of the glass sections. Visual and infrared cameras were used to image the unexposed face of each wall assembly during the fire exposure. Results of glass breakage and subsequent glass fall out were compared to studies in the literature for glass sections exposed to compartment fires. The behavior of the glass wall assembly under a fire load is presented.

The spatial structure(s) of the Belgian housing stock

This paper presents the spatial structure(s) of the Belgian housing stock and the spatial outcome of socio-economic inequalities at a (sub)regional level and shows the link with the cultural landscape. A selection of housing patterns illustrates the processes that segment the Belgian housing stock today: north–south contrasts, east–west differences, centre–periphery and urban–non-urban dualities.

An Artificial Neural-network Based Predictive Model for Pre-evacuation Human Response in Domestic Building Fire

The post-1993 WTC attack study (Proulx and Fahy, In: Proceedings of ASIAFLAM’95—An International Conference on Fire Science and Engineering, Hong Kong, 1995, pp 199–210) revealed that occupants took 1–3 h to leave the 110-storey buildings, and the pre-movement reactions could account for over two-thirds of the overall evacuation time. This indicates that a thorough understanding of the pre-evacuation behavioral response of people under fire situations is of prime importance to fire safety design in buildings, especially for complex and ultra high-rise buildings. In view of the stochastic (the positions of the occupants) and fuzzy (uncertainty) nature of human behavior (Fraser-Mitchell, Fire Mater 23:349–355, 1999), conventional linear and polynomial predictive methods may not satisfactorily predict the people’s response. An alternative approach, Adaptive Network based Fuzzy Inference System (ANFIS), is proposed to predict the pre-evacuation behavior of peoples, which is an artificial neural network (ANN) based predictive model and integrates fuzzy logic (if-then rules) and neural network (based on back propagation learning procedures The ANFIS learning architecture can be trained by structured human behavioral data, and different fuzzy human decision rules. The applicability in simulating human behavior in fire is worth exploring.

Evaluation of Surfactant Enhanced Water Mist Performance

Water-mist technology provides efficient fire suppression for compartments while minimizing water usage. Even with the many advantages of water mist systems, there is still room for improvement. Water mist systems have demonstrated effectiveness at suppressing flammable liquids (Class B) fires in compartments. However, an especially challenging fire suppression scenario for water mist systems is the small Class B fire. This scenario is often realized after a large fire has been reduced in size or ‘controlled’ by water mist. The small fire scenario is challenging because a small fire may not be able to generate enough vaporized water to displace sufficient oxygen for complete extinction. It should also be noted that even if the Class B fire is extinguished with a water mist system, re-ignition from the hot surrounding surfaces may occur at any time. In the present work, an additive is introduced into the water supply and its effect on the water mist suppression performance is studied. This Forafac^TM additive is a specific formulation, which includes fluorinated surfactants for creating a robust fire suppression foam. The enhanced suppressant exiting the mist nozzle is dispersed in the form of small droplets (not as a continuous foam) similar to a pure water mist spray. However, these droplets create a foam blanket on the surface of the fire, which acts to isolate the fuel from the air. With this formulation, the efficiency of the water mist system is improved even on small fires and most importantly the re-ignition of class B fires is prevented.

A time series analysis of U.S. metropolitan and non-metropolitan income divergence

This paper employs time series methods to analyze convergence across metropolitan and non-metropolitan regions during the 1969–2001 period. The results suggest that non-metropolitan regions are diverging from below the U.S. average income level, while metropolitan regions show mixed evidence of convergence. These summary results vary by geographic location and the size of the region, with medium-sized metropolitan regions showing the strongest tendencies to converge, while non-metropolitan areas with larger urban centers and small towns showed the strongest tendencies to diverge. Differences in human capital (as well as employment concentrations in farming and mining) appear to have influenced the relative performance of metropolitan and non-metropolitan regions during the last 30 years, suggesting a role for agglomeration economies in the observed trend toward divergence.

The Reverse Side of the Medal: About the 2010 FIFA World Cup and the Beautification of the N2 in Cape Town

This paper aims to show the reverse side of the (football) medal. The N2 gateway project in Cape Town is presented, by government and media, as a ‘flagship’ project of the new Breaking New Ground strategy, to fight the housing backlog of 400,000 houses in the city. But I want to argue that the fast-tracking of the project has to be understood as a beautification strategy to prepare the city for 2010. Massive slum eradication and the construction of ‘beautiful formal housing opportunities’ between the airport and the mother city are becoming a painful reminder of the forced removals under the apartheid regime.

The Role of Mobile Phones in Tanzania’s Informal Construction Sector: The Case of Dar es Salaam

This paper explores how mobile phones are being used by informal construction workers in Dar es Salaam, Tanzania. It reveals that ownership of mobile phones is stratified along employment lines. This observation acts as a good indicator of what is now perhaps the biggest split in employment in many developing economies: a split between a stratum of employers and middlemen (who in Dar es Salaam’s informal construction sector are also mostly using mobile phones), and a stratum of employees, apprentices, family labourers and marginal-owner operators (who are generally not using mobile phones). The applicability of government policy on information and communication technology (ICT) is assessed in the context of these findings. This leads to the suggestion that since Tanzania’s small-enterprise development policy concentrates on use of the internet, much of this is irrelevant to the majority of informal-sector construction enterprises which – when they do use ICT – rely almost exclusively on mobile phones as a significant cost-saving device.

Innovation and regional absorptive capacity: the labour market dimension

In 2003, Eurostat published an ‘experimental’ dataset on regional innovation levels derived from the Second Community Innovation Survey. This dataset, part of the European Innovation Scoreboard, also contains a range of regional labour market indicators. In this paper, we report an exploratory analysis of this data, focussing on how the labour market characteristics of regions shape regions’ absorptive capacity (RACAP) and their ability to assimilate knowledge from public and externally conducted R&D. In particular, we aim to establish whether labour market aspects of RACAP are more important for innovation in prosperous or lagging regions of the European Union (EU).
