By reason of their generally longer travel times, transit users are not so well-served by many public facilities as are automobile drivers. This paper investigates the implications of this fact for the location of a specific type of service, public child day care. A location-allocation model is employed to determine the most accessible locations for a set of centres in Edmonton, Canada, for users of both modes. Transit is found to be capable of providing only 51% of the accessibility of the automobile, at 2.4 times the average travel time. The argument is advanced that in order to reduce the inequality of service to a minimum, public facilities should be located with the accessibilities of transit users in mind. The optimal systems are compared with Edmonton's present system which is found to be spatially inefficient and quite discriminatory in its inefficiency against transit users. This is attributed to the city's piecemeal planning policy and an inadequate understanding of the notion of accessibility. The paper concludes by recommending improvements which would improve our simple diagnostic model to the level of a useful planning device. 相似文献

Asset pricing theory and the valuation of Canadian paintings 总被引:1,自引:0,他引:1
Abstract. The valuation of Canadian paintings is analysed empirically. Using a sample of auction prices for major Canadian painters for the period 1968–2001, we run hedonic regressions to analyse the influence of various factors, including painter identity, on auction prices, as well as to construct a market price index. This index is used in a second‐stage analysis in which we analyse the properties of Canadian art viewed as an investment asset. We apply standard asset pricing theory, as incorporated in the capital asset pricing model (CAPM), to the analysis of price movements in the market for Canadian paintings. 相似文献

The present article focuses on the conditions that allow governments to increase property rights protection because they expect enough income from such action. We develop a behavioral explanation, according to which the answer lies in the growth in the importance, size and wealth of merchant guilds in the medieval era in Western Europe as well as a somewhat surprising effect of volatile price structures. We add to prior research by showing that even uncoordinated embargo pressures among multiple guilds could get medieval rulers to offer high levels of property rights protection. 相似文献

The residuals of the equations of the St. Louis model are analyzed individually and in pairs, using time series techniques in an attempt to discover mis-specifications in the model, in the form of incorrect lags or missing variables. The relationships discovered are,checked both inside and outside the sample. A variety of mis-specifications are apparent, and a much improved specification should be possible. The assumption made in the model that money supply is exogenous does not agree with the data. 相似文献

We examine the value relevance of accounting across several African countries and test whether IFRS improved the value association of earnings and equity book values. We report a stronger valuation association between accounting and stock prices in African countries classified as having a secrecy culture. This increases after IFRS and more so for earnings. On the other hand, IFRS induced a stronger increase in the book value coefficient in the less secretive and more developed South African market. We surmise that the more conceptual focus of IFRS induced an increased demand for higher‐quality accounting professionals, which had a filtering‐down effect of improving quality information flow and breaking down the secrecy culture. Our research highlights the diverse impacts of IFRS and the role of culture, asset markets and accounting professionalism, in driving the relevance of accounting components across Africa. 相似文献

The quality and cost of hospital care depends not only on what technologies have been developed, but on how quickly the most promising and cost-effective technologies diffuse across hospitals. Some technologies are high-cost when they are first introduced into the health care system, but improve in cost-effectiveness as doctors use the technologies and innovate. Some such examples are minimally invasive procedures, which have become more common in recent years. We sought to better understand what hospital characteristics are associated with fast adoption of four minimally invasive procedures (appendectomy, lobectomy, hysterectomy and colectomy). Our findings show that a hospital’s adoption of minimally invasive procedures in one type of procedure (e.g., lobectomy) is not predictive of that hospital’s probability of adopting minimally invasive procedures in another procedure type (e.g., zero appendectomies). The only hospital characteristic consistently correlated with adoption for three of the four procedure types was the extent that the hospital’s geographic neighbors had adopted minimally invasive technology for that particular procedure. These findings regarding peer effects fall in line with conclusions about diffusion from the development literature. 相似文献

Background: EOX (epirubicin, oxaliplatin, Xeloda; capecitabine) and FOLFOX4 (5-fluorouracil (5-FU), leucovorin, oxaliplatin) are the common chemotherapy regimens used in the treatment of advanced gastric cancer (aGC) in Hong Kong. This study aimed to compare the costs of these therapies for aGC patients from both the healthcare and societal perspectives. It should be noted that, while FOLFOX4 is routinely administered in an outpatient setting in North America and Europe, inpatient setting is adopted in Hong Kong instead, incurring hospitalization cost as a result.Methods: Fifty-eight patients were identified from the electronic records in two public tertiary hospitals, with 45 and 13 receiving EOX and FOLFOX4 regimens, respectively. Healthcare cost was direct medical costs including drugs, clinic follow-up, hospitalization, diagnostic laboratories, and radiographs. Societal cost refers to indirect costs such as patient time and travel costs. Cost items were further classified as “expected” or “unexpected”. All cost data was expressed in US dollars.Results: Patients in the EOX and FOLFOX4 arm received an average of 5.3 and 7.8 cycles of treatment, respectively. The capecitabine-based regimen group had a higher expected medication cost per cycle when compared to the 5-FU-based treatment group (US$290.3 vs US$66.9, p?.001), but lower expected hospitalization costs (US$76.9 vs US$1,269.2, p?.001). The total healthcare cost and total societal cost per patient was reduced by 67.2% (US$5,691.9 vs US$17,357.4, p?.001) and 25.3% (US$3,090.5 vs US$4,135.1, p?=?.001), respectively, in the capecitabine-based regimen group. Sensitivity analyses based on full cycle regimen costs and net capecitabine or 5-FU/leucovorin costs still showed EOX to be less costly than FOLFOX4.Conclusion: The capecitabine-based regimen, EOX, was found to generate significant cost saving from both the healthcare and societal perspectives in regions in which FOLFOX4 is given in an inpatient setting. 相似文献
