Consumer susceptibility to reference group influence has been demonstrated for certain products and buying situations. This
article reports a study designed to determine if reference group influence varies between consumers classified as situationally-oriented
and dispositionally-oriented. Results indicate a considerable difference between the two groups.

The development of a standardized student evaluation form 总被引:1,自引:0,他引:1
David J. Lill Ph.D. 《Journal of the Academy of Marketing Science》1979,7(3):242-254
The original purpose of student evaluations was to provide feedback to the instructor to improve his/her teaching. However,
the use of student evaluations in assessing promotion and tenure decisions is becoming increasingly apparent. Given that students
represent one valuable source of evaluation data, the task involves gathering the information so as not to bias or influence
the results. Thus, the objectives of this report are to discuss the methodology and pitfalls in the construction of a data
collection instrument, and produce a “model” student evaluation form that may serve as the basis for establishing validity
by having the academic community put it to the test. 相似文献

Previous studies of the driving times of shopping center patrons have not examined the effect of limited access highways.
This study analyzed the impact of interstate highways on the driving times of 204 shoppers at three medium-sized regional
shopping centers. Those shoppers indicating usage of interstate highways to reach their shopping destinations were significantly
more likely to incur travel times greater than fifteen and twenty minutes than those not using the available interstate roads.
In predicting the drawing power of these shopping centers, factors besides mass were found to be useful. These include square
footage of shopping goods, stores, and number of parking places. 相似文献

The efficiency of a research design may be measured in terms of the degree to which knowledge is enhanced within given resource
constraints. Thus, two different types of research design, even though they contain the same number of expected observations,
may differ considerably in the amount of information provided. An example is the number N of 32 observations obtained with
an analysis of variance witheither 2 factors, 2 levels per factor and a replication of 8or 4 factors, 4 levels per factor and a replication of 2. We analyze and compare the relative efficiencies of regression and
variance analysis models and their implications to research strategy development. Three major considerations are evaluated:
(1) short versus long time horizon (interval until effects of a decision are realized), (2) small versus large cost of erroneous
rejection of the Null Hypothesis and (3) gross versus refined stage of development of the research study. A set of general
guidelines towards improved designs is developed. 相似文献

The implementation plan will remain the same: target an area of opportunity, measure and document the amount and value of the unofficial inventory, establish PAR levels, implement the use of hand-held terminals to assist in inventory control, and integrate inventory control with the implementation of new programs that will impact ordering, receiving, distribution, and invoicing. It is anticipated that the inventory in the main OR alone can be reduced by $1.5 million if we move forward with a stockless JIT system. This would reduce the days of inventory on hand from approximately 100 days to between 7 and 14 days. This could also mean a holding cost reduction of $150,000. The merit of reducing unofficial inventory is evident. Managing unofficial inventory is merely one piece of the successful materiel management foundation. The other foundation pieces include contract compliance and price negotiations, systematic methods of ordering products, and timely distribution of products to the end user. PHS cannot effectively move forward to a new, innovative materiel system for the future until we first measure, analyze, and document the present conditions. Once the foundation is laid by improving present business practices, then the framework of the structure can be designed and constructed. The goal is to implement a system that utilizes the full potential of people, equipment, logistics, and information so that our customers, the patient caretakers, do not have to worry about anything except the delivery of quality care.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献
