The Use of Video Modeling,Prompting, and Feedback to Increase Credit Card Promotion in a Retail Setting

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 Austin, J. 2000. “Performance analysis and performance diagnostics”. In Handbook of applied behavior analysis, Edited by: Austin, J. and Carr, J. E. 321–349. Reno, NV: Context Press.  [Google Scholar]) 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.     

Estimation of a Change Point in a Hazard Function Based on Censored Data

The hazard function plays an important role in reliability or survival studies since it describes the instantaneous risk of failure of items at a time point, given that they have not failed before. In some real life applications, abrupt changes in the hazard function are observed due to overhauls, major operations or specific maintenance activities. In such situations it is of interest to detect the location where such a change occurs and estimate the size of the change. In this paper we consider the problem of estimating a single change point in a piecewise constant hazard function when the observed variables are subject to random censoring. We suggest an estimation procedure that is based on certain structural properties and on least squares ideas. A simulation study is carried out to compare the performance of this estimator with two estimators available in the literature: an estimator based on a functional of the Nelson-Aalen estimator and a maximum likelihood estimator. The proposed least squares estimator tums out to be less biased than the other two estimators, but has a larger variance. We illustrate the estimation method on some real data sets.

Analyse biographique du travail féminin

Cet article montre comment l'application d'une méthode d'analyse biographique d'interaction à un domaine où l'interaction paraît évidente — activité féminine et fécondite — ouvre des perspectives nouvelles. En effet, les limites qui apparaissent lors de cette analyse conduisent les auteurs à conclure que ce n'est pas en raffinant les méthodes mais plutôt la collecte que l'on parviendra à progresser dans ce domaine. Le problème des interactions de l'activité et de la fécondité semble mal posé avant même le recours à la méthode. Cela justifie la nécessité de saisir le travail féminin comme concept unifié ne dissociant pas la sphère domestique et la sphère rémunérée. Cela conduit les auteurs à dégager quelques principes de collecte mieux adaptés aux préoccupations récentes dans ce domaine: des données biographiques sur le travail féminin. L'interaction collectée à sa source se prêterait alors à une analyse biographique plus révélatrice que celle qui confronte deux processus sans en évaluer les modalités changeantes.This article demonstrates how life event history analysis applied to the interaction between fertility and female economic activity can lead to new perspectives in the analysis of this complicated relationship. The authors identify limits to the analysis of the interaction given the anticipatory nature of behaviour. They conclude that progress in this field requires not the refinement of methods but rather a fundamental change in the approach to the data collected. If fertility and employment are considered separately, a problem is created even before the methods of analysis are applied. They recommend a conception of women's work as a whole, a conception that does not dissociate domestic and paid work. The authors go on to identify ways of improving the relevance of data collection to contemporary issues in the life history analysis of women's work. They argue that data on the interaction, collected at its source, would yield a more revealing life history than that which sees domestic work and paid work as separate spheres, and fails to take account of changes in their relationship.

Security level,potential level,expected utility: A three-criteria decision model under risk

Among the violations of expected utility (E.U.) theory which have been observed by experimenters, the violations of its independence axiom is, by far, the most common. It seems that, in many cases, these inconsistencies can be ascribed to the desire for security - called the security factor by L. Lopes (1986) - which makes people attach special importance to the worst outcomes of risky decisions as well as to the sole outcomes of riskless decisions (certainty effect). J.-Y. Jaffray (1988) has proposed a model which generalizes E.U. theory by taking into account this factor and is then able to account for certain violations. However, especially in experiments on choice involving prospective losses, violations of the von Neumann-Morgenstern independence axiom cannot be explained by the security factor alone and have to be partially ascribed to the potential factor (L. Lopes, 1986) which reflects heightened attention to the best outcomes of decisions, especially when the best outcome is the status quo. In this paper, we construct an axiomatic model for subjects taking into account simultaneously or alternatively the security factor and the potential factor. For this, as in Jaffray's model, it has been necessary to weaken not only the standard independence axiom but also the continuity axiom and, in the same time, to reinforce the dominance axiom. In the resulting model, choices are partially determined by the mere comparison of the (security level, potential level) (i.e. the (worst outcome, best outcome)) pairs offered, and completed by the maximization of an affine function of the expected utility, the coefficients of which depend on both the security level and potential level.In this model, a decision maker who (i) has constant marginal utility for money, (ii) is sensitive to the security factor alone in the domain of gains, (iii) is sensitive to the potential factor alone in the domain of losses, behaves as a risk averter for gains and a risk seeker for losses.     

Independent directors,large shareholders and firm performance: the generational stage of family businesses and the socioemotional wealth approach

The effectiveness of independent directors is empirically addressed in the Southern European context using a sample of 221 publicly traded firms during the 2001–2007 period. Drawing on the socioemotional wealth approach, we focus on family control and influence to test whether there are significant differences in the effect of independent directors on the firm’s performance among non-family businesses (NFBs) that have a non-family large shareholder, and family businesses (FBs). In doing so, we consider the heterogeneity of FBs by testing whether the FB’s life cycle moderates the effectiveness of independent directors. To that end, we differentiate among founder lead family businesses and non-founder lead family businesses. Moreover, we test whether dual leadership structures, in particular when the family chief executive officer is also the chairperson of the board, moderates the effectiveness of independent directors. A cross-country and panel data design was used, taking into account the endogeneity problem arising in studies of corporate governance. The results show that the contribution of independent directors to a firm’s performance differs for NFBs and FBs. Moreover, findings confirm that in FBs, contribution is moderated by the generational stage of the FB and by the leadership structure of the firm.     

女性移民问题与女权主义干预

通过1990年至1991年对蒙特利尔社会服务系统内40位社会干预工作者的调查发现,女性移民最关注的社会问题,主要是移居导致的对传统性别角色分工的质疑和生理、心理健康问题。因此,主张在针对女性移民的社会工作干预实践中,应当加强女权主义干预的应用,以唤起对性别角色分工、妇女面临的社会问题和对妇女的偏见的认识为目标,鼓励干预者在尽可能平等的基础上和被帮助的妇女进行交流,以解决女性移民面临的各种问题。
