Restaurant Revenue Management at Chevys: Determining the Best Table Mix

Revenue management has been used in a variety of industries and generally takes the form of managing demand by manipulating length of customer usage and price. Supply mix is rarely considered, although it can have considerable impact on revenue. In this research, we focused on developing an optimal supply mix, specifically on determining the supply mix that would maximize revenue. We used data from a Chevys restaurant, part of a large chain of Mexican restaurants, in conjunction with a simulation model to evaluate and enumerate all possible supply (table) mixes. Compared to the restaurant's existing table mix, the optimal mix is capable of handling a 30% increase in customer volume without increasing waiting times beyond their original levels. While our study was in a restaurant context, the results of this research are applicable to other service businesses.

Distribution of Exposure Concentrations and Doses for Constituents of Environmental Tobacco Smoke

The ultimate goal of the research reported in this series of three articles is to derive distributions of doses of selected environmental tobacco smoke (ETS)-related chemicals for nonsmoking workers. This analysis uses data from the 16-City Study collected with personal monitors over the course of one workday in workplaces where smoking occurred. In this article, we describe distributions of ETS chemical concentrations and the characteristics of those distributions (e.g., whether the distribution was log normal for a given constituent) for the workplace exposure. Next, we present population parameters relevant for estimating dose distributions and the methods used for estimating those dose distributions. Finally, we derive distributions of doses of selected ETS-related constituents obtained in the workplace for people in smoking work environments. Estimating dose distributions provided information beyond the usual point estimate of dose and showed that the preponderance of individuals exposed to ETS in the workplace were exposed at the low end of the dose distribution curve. The results of this analysis include estimations of hourly maxima and time-weighted average (TWA) doses of nicotine from workplace exposures to ETS (extrapolated from 1 day to 1 week) and doses derived from modeled lung burdens of ultraviolet-absorbing particulate matter (UVPM) and solanesol resulting from workplace exposures to ETS (extrapolated from 1 day to 1 year).     

服务型政府研究文献的统计分析——以中国期刊网篇名含“服务型政府”的文献为考察对象

服务型政府是近年来学界研究的热点。以中国期刊网篇名含“服务型政府”的文献为考察对象,对服务型政府的概念、研究领域、分析视角、如何构建以及相关问题的具体分析,不难发现,当前我国的服务型政府研究存在着对于服务型政府的前景过于乐观,研究内容不够全面,研究视角、方法选择重复,研究中的本土化优势挖掘不够等问题。因此,应准确认识、理性对待、深入反思、科学选择、细化研究,从而完善我国的服务型政府研究。     

品牌个性维度的本土化研究

品牌个性维度一直是营销理论研究和营销实践领域中的一个热点课题。Jenniffer Aaker于1997年首次系统地发展了基于美国的品牌个性维度及量表,日本和西班牙的品牌个性维度及量表也相继诞生。然而,中国的本土化品牌个性维度及量表却仍然是一个空白。本文首先采用了西方的词汇法、因子分析和特质论作为方法论基础,以来自中文语言、中国的品牌为内容,经中国消费者的实证研究发展出中国的品牌个性维度及量表,并从中国传统文化角度阐释了中国的品牌个性维度——“仁、智、勇、乐、雅”。然后本文对中国的品牌个性维度与美国、日本的品牌个性维度进行了跨文化比较研究。     

经济学视角下的高校教育成本核算问题

高校教育成本应从经济学视角和会计学视角下分析,坚持权责发生制、收入与费用相匹配、划分收益性支出和资本性支出、相关性、可操作性、分类核算、会计期间学年制等实计价原则,分清核算存在的制度障碍、政策空白、缺乏实务、项目不统一等难点,明确人员经费、日常公用支出、直接用于学生的费用、固定资产支出、招待费、科研经费、后勤支出等计入标准,分别核算年度教育总成本、年度生均培养成本、毕业生在校期间培养成本.

Managing the International Strategic Sourcing Process as a Market-Driven Organizational Learning System*

This study examines the effects of market-driven organizational learning on a select set of strategic sourcing outcomes involving the sourcing function of a Fortune 500 multinational corporation. The focus is on the dyadic activities and relationships between the domestic and international strategic business units (SBUs) and the corporate buying center. The hypothesized relationships are tested on the overall sample and based on a two-by-two matrix framework defined by international versus domestic settings and frequent versus infrequent sourcing scenarios. Based on a sample of 179 domestic and 167 international SBUs, the results suggest that market-driven organizational learning in the strategic sourcing units influences customer satisfaction, relationship commitment, and cycle time of the sourcing process. However, while the set of learning orientations appears to be strategically robust across the four quadrant scenarios (moderator settings), the sourcing situations differ somewhat in the specific tactical learning orientations preferred.     

An Efficient Class of Estimators for the Population Mean Using Auxiliary Information in Stratified Random Sampling

This article addresses the problem of estimating the population mean in stratified random sampling using the information of an auxiliary variable. A class of estimators for population mean is defined with its properties under large sample approximation. In particular, various classes of estimators are identified as particular member of the suggested class. It has been shown that the proposed class of estimators is better than usual unbiased estimator, usual combined ratio estimator, usual product estimator, usual regression estimator and Koyuncu and Kadilar (2009 Koyuncu, N., Kadilar, C. (2009). Ratio and product estimators in stratified random sampling. J. Statist. Plan. Infere. 139:2552–2558.[Crossref], [Web of Science ®] , [Google Scholar]) class of estimators. The results have been illustrated through an empirical study.     

《东海岛屿文化与民俗》序论

《东海岛屿文化与民俗》是继《吴越地区民间信仰民俗》和《稻作文化与江南民俗》之后的关于吴越地区民俗文化的系列研究成果。由于海岛的独特性,该课题在调查方法上,突破了以往民俗学的"投入式调查"和"参与式调查"模式,而探索到了第三种调查方式,即以当地土生土长的文化人来调查和描述本地的民俗文化,实践证明,这种方式也是行之有效的。民俗学在理论上还存在着让人探索的广泛空间,以马克思主义的辩证唯物论和唯物辩证法为方法论来建立中国的民俗学学派,有着崭新的发展前景。
