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.     

Personal income taxation under mobility, exogenous and endogenous welfare weights, and asymmetric information

This paper analyses how governments should tax labour income accruing to a group of highly skilled and geographically mobile individuals who divide their time or career between several jurisdictions. The analysis differs from previous models on migration and taxation by addressing optimal regulation when agents work for several principals. Optimal taxation is developed for social welfare functions with exogenous and endogenous welfare weights. Marginal income taxes are applied for screening purposes, and the rates are lower with endogenous than with exogenous welfare weights. Received: 22 January 1998/Accepted: 3 July 1999)     

Cajun is Dead – Long Live Cajun: Shifting from a Linguistic to a Cultural Community

Researchers have reported an evolution or change in progress in the Cajun identity, though their intuitions have not been confirmed empirically. The traditional membership borders of what a community consists of no longer apply in the case of Cajun. In order to understand these questions of identity and belonging, and to scientifically control the interpretation of the linguistic behavior of Cajun speakers, a general survey has been conducted on the linguistic attitudes and cultural identity of a sample of 929 individuals stratified by age and sex from four communities. Our results show that Cajun identity rests fundamentally in the linguistic ability of the speakers, regardless of the age group one is in: the more one has access to the Cajun language, the more one self-identifies as Cajun. In general, respondents claim that the necessary criteria to be considered Cajun are just those criteria that they themselves satisfy. We will demonstrate that there appear to be several 'paths' to take insofar as the Cajun community identity in Louisiana is concerned. However, this segmentation obviously has not been established or maintained without creating considerable tension between members of the cultural Cajun community.     

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.     

Peach Trees Grow in the Spaces Between People: Counselling Practices in the Territory of Violence

In this paper the authors reflect on how therapeutic practices wove a community of care and concern with a young man in South Africa who was at risk of anger ruling his life. A counselor and outsider witnesses participated in responding to the problems the young man and his family faced. The authors discuss the steps they took in the therapeutic journey and describe how their personal and professional lives were shaped by this collaboration. This work inspires and sustains their enthusiasm in seeking to understand how to best respond when positioned to counsel.     

Immigrant Children: Their Experience of Violence at School and Community in Host Country

This article describes our qualitative sociological study of immigrant children's life experiences of violence. We conducted interviews with 42 first‐generation immigrant children from any country, aged 9–13 years old, living in the Quebec City region (Canada). Results from three main themes are presented: representations of violence and concrete violent acts experienced; perceived effects of violence on children health and well‐being; and reactions and coping strategies. Overall, the narratives show that they may experience racist peer violence in school that leads to suffering situations, and they consequently have to develop strategies to maintain their well‐being. Social implications are discussed.     

Nested patterns in urban butterfly species assemblages: respective roles of plot management,park layout and landscape features

Increasing numbers of cities are currently developing sustainable policies aimed at promoting urban biodiversity and ecological dynamics through the planning of green networks and the implementation of more sustainable management practices. These human activities can strongly influence environmental factors on which the organization of ecological communities at different scales depends. Thus, it is of fundamental importance to understand the relative impact of local management, green space design and landscape features on the distribution and the abundance of species in urban areas. On the basis of 2 years of butterfly surveys in urban public parks within an extensive Mediterranean metropolitan area, Marseille (South-East France), the aim of this paper is to provide a better understanding of the effect of these three environmental scales (plot, park, landscape) on the composition and organization of species assemblages. Using variation partitioning and nestedness analysis on ecological data aggregated at plot-level and park-level respectively, we demonstrate the preponderant effect of landscape scale features on urban butterfly assemblages. Our results also highlight an important co-variation of plot management, park layout and urban landscape features, in their interaction with the community structure of urban butterflies. Although there is no significant species-area relationship, significantly nested patterns arise in species composition. Selective colonization appears as a driving force constraining the constitution of species assemblages within the city. However, a prospective study on adjacent more natural areas suggests that biotic limitations, interspecific competition and habitat filtering may play an important role if a larger portion of the urbanization gradient is explored, which remains to be investigated.
