A simple management model for irregularly located wells is presented by considering interference between adjacent wells at a certain risk level and safe groundwater velocity which depends mainly on the hydraulic conductivity at individual well sites. The final decision variables for a confined aquifer are the maximum allowable discharge, velocity, and drawdown quantities. Regional variations of these quantities are presented in the form of maps which are most useful tools for identifying mismanagement areas and, accordingly, the necessary precautions can be taken. The application of the management model is performed with the actual field data from the Saq formation in the north-western part of the Kingdom of Saudi Arabia. 相似文献

Abstract. Faced with divergent opinions among consumers on the use of genetically modified (GM) foods, Canada has adopted a voluntary labelling approach for non‐GM foods, whereas the European Union has a mandatory labelling policy for GM foods. Interestingly, both labelling systems have resulted in very little, if any, additional consumer choice. Using an analytical model, we show that the coexistence of GM and non‐GM products at the retail level depends on the labelling policy, consumer perceptions, and the type of product. Although voluntary labelling tends to favour the use of GM products, it is more likely to provide consumer choice. 相似文献

Accurate assessment of farmers' credit constraint condition is important in order to understand the circumstances under which credit would have its greatest impact. In this study a switching regression model was used to determine the impact of credit on smallholder dairy farms in the East African highlands using farm level data from Ethiopia and Kenya. Farmers were classified as credit constrained or credit non-constrained based on their responses from the farm level surveys. No consistent relationship was found between farmers' credit constraint condition and their borrowing status. Most of the variation in milk output per farm was explained by the number of crossbred milking cows in the dairy herd. As credit is likely to facilitate investment in crossbred dairy cows it will have substantial impacts on smallholder dairy farms especially if it is targeted to credit constrained farms. 相似文献

The proxy hypothesis states that the negative relationship between inflation and stock returns is spurious and really only proxies for the positive relationship between stock returns and real variables. Previous testes of the proxy hypothesis have used actual values instead of forecasted values for the real activity variable. Using only forecasted variables, our results do not support the proxy hypothesis. 相似文献

Islamic Banks (IBs) are considered as having ethical identity, since the foundation of their business philosophy is closely tied to religion. In this article, we explore whether any discrepancy
exists between the communicated (based on information disclosed in the annual reports) and ideal (disclosure of information deemed vital based on the Islamic ethical business framework) ethical identities and we measure
this by what we have termed the Ethical Identity Index (EII). Our longitudinal survey results over a 3-year period indicate the overall mean EII of only one IB out of seven surveyed to be above average. The remaining six IBs suffer from disparity between the communicated and ideal ethical identities. We further found the largest incongruence to be related to four dimensions: commitments to society; disclosure
of corporate vision and mission; contribution to and management of zakah, charity and benevolent loans; and information regarding top management. The results have important implications for communication
management if IBs are to enhance their image and reputation in society as well as to remain competitive.

ABSTRACTThe purpose of this study, grounded in activity theory, is to empirically investigate the communal and individual mechanisms that simultaneously shape the customer experience in group-oriented event tourism. Based on a survey of 389 respondents with group travel experience to major events, the results confirm the research model, suggesting that the customer-experience construct constitutes a multidimensional structure comprising second-order components reflecting individual and communal experiences, with each containing first-order constructs. The results further confirm that the customer-experience construct predicts post-consumption evaluations of perceived value and satisfaction. Limitations of the study are outlined, and implications for research and managerial practice for the creation of customer experiences that are valuable and satisfying for group-travel consumers to events are discussed. 相似文献

A risk-based evaluation is performed for meeting future water demands in the Brahmaputra Floodplain Area within Bangladesh
(BFA). This evaluation is carried out using three risk-based performance indicators: reliability, resiliency and vulnerability.
The vulnerability indicator has been redefined incorporating the aspect of a supply failure. The analysis includes the impacts
of climate change on both water demands and resources, and the generation of synthetic flows of the Brahmaputra River using
time series models. The simulated values of the indicators reveal that the expected demand of the BFA up to the year 2050
can be supplied with the proposed Brahmaputra Barrage inside Bangladesh under the ‘no change’ in climatic condition, provided
that the groundwater remains usable. However, if groundwater becomes unusable due to widespread arsenic contamination and/or
a climate change occurs, it would not be possible to meet the future water demand of the region with high reliability, moderate
resiliency and low vulnerability. 相似文献

We explore the potential firm and industry characteristics that determine the corporate social responsibility (CSR) disclosure practises by Bangladeshi listed firms. We use a CSR disclosure checklist to measure the extent of CSR disclosure in the annual reports and a multiple regression analysis to examine the determinants of CSR disclosure. Our study finds that CSR disclosure has positive and significant relationships with export-oriented sector, firm size and types of industries. We also find a negative relationship between CSR disclosure and family ownership. The overall findings of our study provide empirical evidence which suggests that a number of firm and industry characteristics are important determinants of the extent of CSR disclosures in a developing country like Bangladesh. Our findings can help the policy makers to adopt necessary regulatory reform to improve the CSR practises and enhance organisational legitimacy. 相似文献

This paper models and estimates exchange rate pass-through and its determinants in Canadian manufacturing industries. The paper predicts theoretically that the exchange rate pass-through should be between one and zero, where it is positively affected by the share of tradable inputs in production costs and the domestic firms’ market share, and negatively by the elasticity of marginal cost with respect to output. The sign for the degree of product differentiation is not theoretically clear. Results of estimation indicate that pass-through is incomplete and is mostly affected by the share of tradable inputs in production costs (positively) and the elasticity of marginal cost with respect to output (negatively). 相似文献
