We evaluated the use of video modeling, role play, prompting, and feedback to increase credit card promotion by sales associates in a retail setting. We first used the Performance Diagnostic Checklist (Austin, 2000) to identify the variables contributing to the poor performance of two sales associates. Based on the results, we developed an intervention package that included a video model, instructional prompt cards, role play, and feedback. During baseline, target employees asked a mean of 26% of customers to enroll in the credit card program. Following intervention, target employees asked a mean of 84% of customers to enroll in the credit card program. Furthermore, employees rated the intervention as enjoyable, as effective, and as a system that they would continue to use. The results illustrate the effectiveness of video modeling, prompting, and feedback in increasing credit card promotions and delivering critical information about the card to daily customers. 相似文献

This paper provides a comprehensive review of space- and place-based criminology, with a focus on the relationship between crime, the built environment, land use, and/or physical geography, through sociological and critical geography lenses. An historical overview of major criminological and spatial theories and contributors is presented before examining the current state of the field. In honor of critical geography's goal to be “a people's geography,”1 this paper aims to be an accessible overview of space- and place-based criminological research, especially for readers who are unfamiliar with these topics. 相似文献

This paper considers the analysis of time to event data in the presence of collinearity between covariates. In linear and
logistic regression models, the ridge regression estimator has been applied as an alternative to the maximum likelihood estimator
in the presence of collinearity. The advantage of the ridge regression estimator over the usual maximum likelihood estimator
is that the former often has a smaller total mean square error and is thus more precise. In this paper, we generalized this
approach for addressing collinearity to the Cox proportional hazards model. Simulation studies were conducted to evaluate
the performance of the ridge regression estimator. Our approach was motivated by an occupational radiation study conducted
at Oak Ridge National Laboratory to evaluate health risks associated with occupational radiation exposure in which the exposure
tends to be correlated with possible confounders such as years of exposure and attained age. We applied the proposed methods
to this study to evaluate the association of radiation exposure with all-cause mortality. 相似文献

The paper presents an extension of decision theory to the analysis of social power. The power of a person, A, over another person, B, is viewed in terms of the effect A has on B's decision. The analysis is based on the idea that B's decision regarding the performance of alternative behaviors is a function of 1) B's utility for the consequences of the behaviors and 2) B's subjective probabilities that the behaviors will lead to these consequences. In these terms, A's power over B lies in A's ability to mediate various consequences for B, contingent upon B's compliance or noncompliance. Subjects were asked to consider eight situations in which hypothetical individuals had to make a choice between two courses of action. In each situation another person (A) was attempting to induce the hypothetical individual (B) to choose one of the alternatives, while various situational factors were influencing B to choose the other alternative. The subjects were asked to consider B's utilities and subjective probabilities in each situation and to indicate whether or not B should comply with A and to make ratings of A's power. The decision theory analysis did well in predicting whether or not subjects would indicate that B should comply with A. Also, subjects generally were able to correctly specify whether A or the situational factors had more influence over B's decision. Finally, the subjects' ratings of A's power in the eight situations were highly related to the decision theoretic measure of power. 相似文献

It is clear from research policy statements throughout Europe and in the USA and Japan that governments are becoming increasingly interested in the well-being of small firms. This is based on a belief in their ability to generate employment, their potential for the industrial regeneration of the so-called development areas and their ability to produce technological innovations. It is to this latter issue—the innovation potential of small firms—that this article is addressed. Further, while most studies of the role of small firms in innovation have been concerned with ‘innovation counts’ and have adopted a rather static approach, we are here concerned with their role in the dynamics of the introduction and diffusion of new technologies, specifically semiconductors and computer aided design (CAD). Moreover, there has in the past been a tendency to emphasize the role of the small firms or the role of large firms in innovation; we reject this rather sterile view and demonstrate the interrelationship between the two. In both areas—semiconductors and CAD—the initial breakthroughs were made in the R&D laboratories of large companies which produced components and equipment for their own use; it was through the actions of new technology-based small firms that these innovations were diffused into more general use. Again in both cases, the basic technological know-how, the entrepreneurs themselves and often the risk capital, derived from the original innovating large companies. Thus, policies that do not take into account the dynamic complementarities between the large and the small clearly are of only limited utility. 相似文献

An identification procedure for multivariate autoregressive moving average (ARMA) echelon-form models is proposed. It is based on the study of the linear dependence between rows of the Hankel matrix of serial correlations. To that end, we define a statistical test for checking the linear dependence between vectors of serial correlations. It is shown that the test statistic t?n considered is distributed asymptotically as a finite linear combination of independent chi-square random variables with one degree of freedom under the null hypothesis, whereas under the alternative hypothesis, t?N/N converges in probability to a positive constant. These results allow us, in particular, to compute the asymptotic probability of making a specification error with the proposed procedure. Links to other methods based on the application of canonical analysis are discussed. A simulation experiment was done in order to study the performance of the procedure. It is seen that the graphical representation of t?N, as a function of N, can be very useful in identifying the dynamic structure of ARMA models. Furthermore, for the model considered, the proposed identification procedure performs very well for series of 100 observations or more and reasonably well with short series of 50 observations. 相似文献

"Studies in Australia show that an increasing proportion of the population have ancestors from more than one country. Evidence regarding differences in the marriage patterns of first and second generation migrants has been restricted in scope as published marriage registration data includes only birthplace of partners. Marriage registration records include information about the birthplace of parents of partners, but is available only through specially produced tabulations. Changes in the census for 1986 and 1991 make it possible to identify the second generation in households, and this article examines the use of census data as an alternative to marriage registration records in tracing changes in intermarriage patterns and differences between urban and rural areas." 相似文献
