With the club industry comprising of different types of clubs, a more in-depth analysis separating clubs with and without golf operations would be beneficial. Financial performance can be summarized via financial ratios. This study surveyed 115 clubs regarding their financial performance and calculated 24 financial ratios for 2014. The median profit margin of all clubs was at 1.65%. Clubs with golf operations reported a median profit margin at 1.73%, doubling that of the nongolf operations at 0.83%. T-tests using means of financial ratios showed a statistically significantly difference in only the food inventory turnover by days.  相似文献

The hypothesis of induced innovation is tested for U.S. agriculture using a high-quality state-level panel data set and three disparate testing techniques—time series, direct econometric, and nonparametric. We find little support for the hypothesis. That conclusion is robust across testing techniques. However, as with all empirical tests of this hypothesis conducted to date, ours focus only on the demand side of the hypothesis. The hypothesis could have been rejected simply because the marginal cost of developing and implementing input-saving technologies for the relatively expensive inputs is greater than for the relatively cheap inputs.  相似文献

Before embarking on the development of rural areas or regions it seems necessary to answer the following key questions: what goals of the parties involved can be realized, and where, when and how? To tackle these questions we have developed a ‘roadmap’, as part of an overall sustainable development procedure for physical planning and spatial management in rural areas. The roadmap is a tool for the process manager and the people involved. It helps to find the way in the exploration of the potential social, economic and ecological benefits of developing the area or region. The purpose of using the roadmap is to alleviate doubts about the advantages of cooperating in pursuit of sustainable development. A back-casting approach is applied to create appealing visions of the future and visualize mutual opportunities worth implementing. In this article we first describe the need for this new roadmap. We then describe its use, step by step and in some detail. An example of the exploration process is described and the strengths and weaknesses of the roadmap are discussed.  相似文献

Statistical Thinking in Empirical Enquiry   总被引:4,自引:0,他引:4  
This paper discusses the thought processes involved in statistical problem solving in the broad sense from problem formulation to conclusions. It draws on the literature and in-depth interviews with statistics students and practising statisticians aimed at uncovering their statistical reasoning processes. From these interviews, a four-dimensional framework has been identified for statistical thinking in empirical enquiry. It includes an investigative cycle, an interrogative cycle, types of thinking and dispositions. We have begun to characterise these processes through models that can be used as a basis for thinking tools or frameworks for the enhancement of problem-solving. Tools of this form would complement the mathematical models used in analysis and address areas of the process of statistical investigation that the mathematical models do not, particularly areas requiring the synthesis of problem-contextual and statistical understanding. The central element of published definitions of statistical thinking is "variation". We further discuss the role of variation in the statistical conception of real-world problems, including the search for causes.  相似文献

A statistical test is applied to explore the possibility that children can affect the efficiency with which parents consume. Parents may receive some economic benefits from children in the form of reverse integenerational transfers that occur because of a positive influence children have on family behavior. Results show that not only do children have an influence on parental consumption, but also that the influence is beneficial. In fact, not accounting for such a benefit could cause an underestimate in such measures as the rate of return to education or the benefits from such governmental programs as Head Start.  相似文献
