That survey research is error prone is not a new idea and different varieties of non-sampling error have been investigated
in the literature as well as consideration being given in many statistics textbooks to the issue of sampling error. The paper
here considers research upon corporate environmental reporting. It compares information provided by corporate environmental
reports with information that survey respondents claim their organization’s environmental report contains. This enables the
accuracy of the claims to be assessed. Consideration is given to two different industries the Water industry and the Energy
industry. Errors due to inaccurate reporting by survey respondents are shown to be relatively infrequent and respondents appear
just about as likely to claim they report information that they do not, in fact, report as to fail to indicate that they report
information that is, in fact, actually reported. 相似文献

Based on the unique historical site culture assets, series of culture activities and constructions are held by Taiwan municipal government positively in recent years to raise local strength. Though the city landscape of Taiwan is far away from the traditional one, the comparison and analysis of foundation of cultural industry and the situation of cultural participation should be carried on to find out the real issues in Taiwan's cultural industry and cultural marketing so as to strengthen the ability of local development. This study finds out the resources of culture administration and the social participation in hope for clearing up the matters of Taiwan's cultural industry development, avoiding type Ⅲ errors, and giving suggestions. 相似文献

We extend the concept of piecewise linear histogram introduced recently by Beirlant, Berlinet and Györfi. The disadvantage of that histogram is that in many models it takes on negative values with probability close to 1. We show that for a wide set of models, the extended class of estimates contains a bona fide density with probability tending to 1 as the sample size n increases to infinity. The mean integrated absolute error in the extended class of estimators decreases with the same rate n–2/5 as in the original narrower class. 相似文献

It is well known that dropping variables in regression analysis decreases the variance of the least squares (LS) estimator of the remaining parameters. However, after elimination estimates of these parameters are biased, if the full model is correct. In his recent paper, Boscher (1991) showed that the LS-estimator in the special case of a mean shift model (cf. Cook and Weisberg, 1982) which assumes no “outliers” can be considered in the framework of a linear regression model where some variables are deleted. He derived conditions under which this estimator outperforms the LS-estimator of the full model in terms of the mean squared error (MSE)-matrix criterion. We demonstrate that this approach can be extended to the general set-up of dropping variables. Necessary and sufficient conditions for the MSE-matrix superiority of the LS-estimator in the reduced model over that in the full model are derived. We also provide a uniformly most powerful F-statistic for testing the MSE-improvement. 相似文献

Utilizing Printed Media to Understand Desired Leadership Attributes in the People's Republic of China 总被引:1,自引:0,他引:1
Using news media as a reliable source, we content analyzed stories on business leaders in two major official Chinese newspapers in three different time periods over the past 20 years. Results show that the reform has brought an increase in stories of business leaders, and in coverage of the desirable leadership attributes relating to Confucian virtues, communist ideologies, and modern management philophies. The results suggest that, by publicizing and adorning specific leaders in both government and business sectors in the official media, the government reinforces the traditional values that are consistent with communist ideologies, and at the same time, it also introduces Western management values to suit the current needs of the society. The results of our study echo the findings of empirical studies on Chinese values that used data collected using other methods. We therefore encourage future research to use the printed media as a potentially valuable source of data for tracking changes in social phenomena in a society over time. 相似文献

Abstract When we talk about “City Development, Preservation, and Hospitality”, we do not forget to discuss Chinese Old Brand Enterprises. These enterprises, labeled with distinctive historical character, enjoy high reputation and wide recognition, are very important parts of urban cultural preservation and economic development. Nowadays, China is called an emerging economy in the world. In fact, China has a long history of business tradition for thousands of years. Especially, Chinese Old Brand Enterprises are those that inherit Chinese traditional culture and bear unique techniques, products, and services in their operations. The urban system in most countries is influenced by market forces and enterprises. Cities that produce goods and services that are in demand and attract people to live in them will have faster growth than those that do not. 相似文献

政府间公共文化财政事权与支出责任划分是基本公共文化服务标准化、均等化的基础性、支柱性保障,当前其划分改革仍存在事权共担模糊性与粗略并存、支出分担概括性与下移并存、财力主导性与保障不足并存,以及省以下划分改革尚未完成等缺憾。划分改革追求“权责清晰、财力协调、区域均衡”的中央与地方财政关系调整目标,但中央与地方的财政分权不能替代省级政府对省以下财政体制改革“负总责”,以及各级地方政府的分级负责。府际协调应坚持中央的统一领导,在省域内落实省级统筹调控功能,并实施地方政府的分级负责,突出“两个积极性”的地方积极性;在体制协调上保持财政事权、支出责任与财力相适应;在机制协调上实施标准化与均等化的衔接配合;在策略协调上强调动态化与确定性的适度平衡。 相似文献
