Effects of transportation accessibility on residential property values: Application of spatial hedonic price model in Seoul, South Korea, metropolitan area

A number of studies have focused on estimating the effects of accessibility on housing values by using the hedonic price model. In the majority of studies, estimation results have revealed that housing values increase as accessibility improves, although the magnitude of estimates has varied across studies. Adequately estimating the relationship between transportation accessibility and housing values is challenging for at least two reasons. First, the monocentric city assumption applied in location theory is no longer valid for many large or growing cities. Second, rather than being randomly distributed in space, housing values are clustered in space—often exhibiting spatial dependence. Recognizing these challenges, a study was undertaken to develop a spatial lag hedonic price model in the Seoul, South Korea, metropolitan region, which includes a measure of local accessibility as well as systemwide accessibility, in addition to other model covariates. Although the accessibility measures can be improved, the modeling results suggest that the spatial interactions of apartment sales prices occur across and within traffic analysis zones, and the sales prices for apartment communities are devalued as accessibility deteriorates. Consistent with findings in other cities, this study revealed that the distance to the central business district is still a significant determinant of sales price.

The Moral Economy of Everyday Crime: Markets, Consumers and Citizens

Between the crimes in the suites and the crimes in the streets lies the mostly unexplored terrain within which we find crimes of ‘everyday life’. Not all of these are formally illegal, but all are generally seen as morally dubious. Most of the crimes of everyday life are committed in the contemporary marketplace, and by those who think of themselves (and are mostly considered by others) as respectable citizens. We contextualize normative orientations that are conducive to such types of behaviour using a framework that links E. P. Thompson’s (1963) concept of the ‘moral economy’ with Institutional Anomie Theory (Messner and Rosenfeld 1994, 2007). Findings from a comparative survey study in three economic change regions (England and Wales, Western and Eastern Germany) show that a syndrome of market anomie comprising distrust, fear and cynical attitudes toward law increases the willingness of respectable citizens to engage in illegal and unfair practices in the marketplace.

Predicting freeway pavement construction cost using a back-propagation neural network : a case study in Henan, China

The objective of this research was to develop a model to estimate future freeway pavement construction costs in Henan Province, China. A comprehensive set of factors contributing to the cost of freeway pavement construction were included in the model formulation. These factors comprehensively reflect the characteristics of region and topography and altitude variation, the cost of labour, material, and equipment, and time-related variables such as index numbers of labour prices, material prices and equipment prices. An Artificial Neural Network model using the Back-Propagation learning algorithm was developed to estimate the cost of freeway pavement construction. A total of 88 valid freeway cases were obtained from freeway construction projects let by the Henan Transportation Department during the period 1994−2007. Data from a random selection of 81 freeway cases were used to train the Neural Network model and the remaining data were used to test the performance of the Neural Network model. The tested model was used to predict freeway pavement construction costs in 2010 based on predictions of input values. In addition, this paper provides a suggested correction for the prediction of the value for the future freeway pavement construction costs. Since the change in future freeway pavement construction cost is affected by many factors, the predictions obtained by the proposed method, and therefore the model, will need to be tested once actual data are obtained.

Motor Accident Insurance Act 1994 - request for information

In Angus v Conelius [2007] QCA 190 the Queensland Court of Appeal concluded that the obligations under the Motor Accident Insurance Act 1994 (Qld), and in particular s 45 of the Act (duty of claimant to cooperate with insurer), continue beyond the commencement of court proceedings
