This paper estimates the quantity of pollutant produced by the Hong Kong hotel industry through diesel oil consumption. A survey of 20 hotels was carried out to collect three years' energy consumption data. Regression analysis indicated that gross floor area was a major and statistically accepted factor in explaining diesel oil consumption. Diesel oil consumption had reduced from the early 1990s and stabilised by the late 1990s. The sulphur dioxide, nitrogen dioxide, carbon dioxide and particulate pollution created by the hotel industry's diesel oil usage from 1990 to 1999 is estimated. The findings indicate that existing green measures and devices are passive and depend on the assimilation of the atmosphere. Environmental costs have stabilised at about HK$54,000 per annum. More proactive approaches to reduce usage and environmental impacts are proposed.  相似文献

Analyzing Real Estate Data Problems Using the Gibbs Sampler   总被引:2,自引:0,他引:2  
Real estate data are often characterized by data irregularities: missing data, censoring or truncation, measurement error, etc. Practitioners often discard missing- or censored-data cases and ignore measurement error. We argue here that an attractive remedy for these irregularity problems is simulation-based model fitting using the Gibbs sampler. The style of the paper is primarily pedagogic, employing a simple illustration to convey the essential ideas, unobscured by implementation complications. Focusing on the missing-data problem, we show dramatic improvement in inference by retaining rather than deleting cases of partially observed data. We also detail Gibbs-sampler usage for other data problems.  相似文献

This study examines the underlying relationships that exist among import competition, employment risk, and worker earnings. In addition, we consider how such competitiveness and risk experienced on a prior job will affect, under both equilibrium and disequilibrium interpretations of the labor market, alternative postdisplacement job-search outcomes. Econometric models of predisplacement earnings and postdisplacement outcomes (jobless duration, reemployment, and earnings) provide insights on these relationships and in turn on the comparative job-search success of trade-displaced and other displaced workers.  相似文献

The literature on wealth effects associated with the announcements of convertible-bond and warrant-bond offerings is reviewed. The findings of 35 event studies, which include 84 sub-samples and 6310 announcements, are analysed using meta-analysis. We find a mean cumulative abnormal return of?1.14% for convertibles compared with?0.02% for warrant bonds, the significant difference confirming a relative advantage for warrant bonds. Abnormal returns for hybrid securities issued in the USA are significantly more negative than those issued in other countries. In addition, issuing hybrid securities to refund debt does not seem to be favoured by investors. Finally, several factors identified as important by theory or in prior research are not significant within our cross-study models, suggesting that more evidence is needed to confirm whether they are robust.  相似文献

Recent years have witnessed a strong and growing interest in the computer science (CS) and information systems (IS) disciplines in applying and extending ontological principles to various CS/IS domains such as knowledge representation, natural language processing, conceptual modeling, and IS development. Similar interest and work have also been observed in accounting information systems (AIS) research. Though ontology research in AIS has enjoyed sustained interest and produced some significant results, there is relatively little incorporation of recent developments in CS/IS ontology research into AIS. This paper provides an overview of some leading areas of ontology research in CS/IS and AIS in an attempt to bridge this gap. The main objectives of this paper are to (1) introduce CS/IS ontology research, (2) highlight areas of future research in AIS where CS/IS ontology research developments can be used to address important and pressing issues, and (3) broaden an area of research where AIS can make unique contributions to distinguish itself.  相似文献

Michel Foucault's concept of governmentality has been central to critical accounting research for two decades, a centrality that has placed systems of calculation as the starting point of discussions of the state, the firm and the market. We begin by outlining the development of governmentality in Foucault's own work. Despite the rich, productive nature of the concept, Foucault was careful to define governmentality as broadly and loosely as possible, the better to convey its open-endedness. The second section considers the introduction of Foucault to accounting research. The combination of Foucault and accounting history is not at all obvious, but became possible because a series of important contextual studies demonstrated that accounting history had to consider both the historicity of the profession and that its practices were vital in constructing measures of organisational performance, not simply uncovering previously obscure or hidden social realities. Moreover, accounting history studies the production of targets and measures of progress towards utility and welfare, processes that are not reducible to the firm or even to economic calculation. Our third section outlines the genesis of the ‘London School of governmentality’ and the main strands of their theoretical contribution. Finally, we examine the governmentalists’ analysis of corporate restructuring and the introduction of new production organisation by Caterpillar. Our aim is to use the Caterpillar case as the vehicle for a broader consideration of governmentality, strategy and the enterprise.  相似文献

Over the last two decades there have been significant and well‐documented changes in the nature and structure of New Zealand dairy production. One particular feature has been a marked shift in the ‘input intensity’ of dairy farming systems through increased use of supplementary feed. These changes have generated debate about the impact of dairy farm intensity on the performance of farm businesses and the competitiveness of the New Zealand dairy sector. Using a novel econometric approach, we assess statistically the impact of three types of dairy farming systems on milk production and financial performance, using farm business data provided by DairyBase®. Our empirical results show that higher input systems perform significantly better physically than lower input systems, but not financially. The disaggregated analysis suggests that the average treatment effects differ by region and performance quantiles.  相似文献
