青海卡力岗人研究综述

自从上个世纪80年代初以来,居住在青海省化隆回族自治县西南部的卡力岗山区的一部分说藏语安多方言,有部分藏族生活习俗的回族穆斯林,日益引起学术界的关注。二十多年来的卡力岗研究取得了一些令人瞩目的成绩,然而也存在着许多显而易见的不足。本文旨在对这二十多年来的研究成果做一个学术回顾,以求为今后的卡力岗研究逐渐走向深入做好准备。     

国内外研究《格萨尔》状况概述

《格萨尔》史诗虽然产生于青藏高原,但是它以独特的魅力,不仅冲出族属的省界,流传于大半个中国,而且早已跨越国境,在许多国家的文苑中竞相开放,为世界人民所喜爱。《格萨尔》研究究竟是从什么时候开始的,经历了怎样的过程?有人说国外对《格萨尔》的研究比国内早,而且成果颇丰,正如敦煌学在中国,而敦煌研究在国外一样。同样,《格萨尔》史诗在中国,而《格萨尔》研究在国外。其实不然,事实上,这部史诗以其“非凡的普及性”引起国外学者注意之前,早就受到了本族学者的热切关注。在国内,研究史诗的历史比国外早近200年,研究成果令人瞩目。     

Marketing Communication Intensity Across Industries

Marketing communication intensity (i.e., the ratio of advertising and promotional expenditures to sales) has been an important topic for both business managers and academics. Here, we investigate cross-sectional and time-series variation of communication intensity due to: type of offering (product versus service) and type of market (consumer versus industrial). Overall, we find that both of these factors affect variation of communication intensity across industries and over time. However, the effect of market type is much more dramatic than the effect of offering type. Such knowledge about patterns in communication intensity levels helps managers make decisions about how much to spend on advertising and promotion.     

On Comparing Alternative Advertising Policies of Pulsation*

In this paper, five alternative advertising policies that belong to the advertising pulsation class are compared analytically for linear and concave response functions using a modified version of the Vidale-Wolfe model. The results of the research show that (1) For both linear and concave response functions, advertising pulsing/maintenance policy dominates advertising pulsing policy but is dominated by the Uniform Advertising Policy. For convex response functions, the order of dominance is reversed. (2) For linear response functions, uniform advertising policy dominates the impulse advertising policy but is dominated by the chattering advertising policy. (3) For concave response functions, uniform advertising policy dominates both the impulse advertising policy and the chattering advertising policy. (4) For convex response functions, chattering advertising policy dominates both the advertising pulsing policy and the impulse advertising policy. The Vidale-Wolfe model is estimated using the well-known Lydia Pinkham data. Optimality analysis shows that the company was overadvertising about half of the time studied. Overadvertising seems to have produced appreciable gain in sales and created significant barriers to competitive entry at a little cost in terms of foregone profits.

Interactive Effects of Major Response Facilitators

Practitioners and researchers have long been interested in achieving the highest response rate within resource constraints on their mailed surveys. Achieving this high response rate typically has required the selection of the right mix of response-facilitating techniques. The selection decisions were generally made under the assumption that the response-facilitating techniques act independently of one another. The authors have examined the validity of this independence assumption by identifying the major response facilitators in use and then analyzing the results of 531 independent mail survey studies. The authors conclude that major facilitators do not function independently. In fact, it was found that significant joint action interactive effects on response rates do exist. Practitioners and researchers who are faced with the survey design decisions of choosing response facilitators can receive assistance by reviewing the results of this diverse collection of reported experiences.     

On Sampling Error in Market Share Estimates*

The relative error in the usual estimator of a brand's market share is reformulated in terms of marketing parameters. Such error is shown to be influenced in an important way by market penetration, as well as by variation in brand and product category volume. Of particular interest is the result that the relative error does not depend on the actual share level. Using data from a marketing research firm that supplies share estimates to the health products industry, we find that the relative error may be substantial even when a large sample is available. An upper bound on this relative error is obtained using marketing parameters that can frequently be measured using industry data and a company's internal records, thus reducing the level of judgmental input required in the planning of sample surveys.     

明清回族进士考略(五)

本文考证了明清时期浙江以及镶黄旗6位进士的生平、事迹及其家世,重点考述了嘉善大姓丁氏。丁氏一族自宋至今千有余年,人才辈出,如明南都工部尚书丁宾、清初诗人丁澎、云贵总督丁思孔,均出自丁氏。丁氏一族来自西域极有可能。本文还提出丁氏可能为宋时入华的中亚国王所非尔之余脉的观点,为进一步深入研究提供了重要的线索。     

关于当前中国农村养老问题及其研究的思考

作为社会的一员 ,老年人有获得社会扶养的权利。如果这种权利不能实现或不能很好实现 ,便形成养老问题。养老问题的研究只能是以认识老年人获得社会保障权利实现过程中的问题并为之谋求对策为根本目的。从这个角度出发 ,养老问题应涵盖四个方面的内容 :(1)“谁来养”的问题 ;(2 )“养不养”的问题 ;(3)“怎么养”的问题 ;(4 )“养得怎么样”的问题。目前 ,这四个方面的问题在农村都存在。而此前的研究因被置于计划生育和老龄化等背景之下而显得不力及过于偏狭 :有限的研究集中于老龄化条件下农村老年人“谁来养”和“怎么养”的问题。这种状况不利于对农村养老问题的全面认识和解决。故笔者认为 ,今后应 (1)全面研究农村养老问题 ;(2 )重视现实 ,分清层次 ,切实研究急需解决的问题 ;(3)在社会变迁的视野下加强农村经济发展、社区建设、文化培育与养老关系的研究
