Instable career paths among workers 45 and over: Insight gained from long-term career trajectories

The study presented in this article focused on the instable career paths of older workers. The study, which is based on the life course approach, had two objectives: 1) identify the main variables which, through their interactions, characterized end-of-career paths; 2) piece together, from the beginning of the career onward, the sequence of key events, transitions, and turning points in the career trajectories that preceded these paths. The results, based on an analysis of in-depth interviews with 32 Canadian workers 45 years and older, showed that these participants' particular career path was characterized by considerable interdependent precariousness whose effects accumulated and intensified as the workers aged. The results also show that this career path was preceded by two distinct career trajectories: one named “fragmented,” which was punctuated by discontinuity and breaks of all kinds, and the other called “severed,” which was characterized by the sudden loss of a career job. Finally, the link between the end-of-career path seen here and the trajectories that preceded it sheds at least some light on the processes that can lead to an instable end-of-career path. These processes were condensed in our discussion into two distinct career biographies.     

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.     

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.     

Positive quadrant dependence tests for copulas

In this paper the interest is in testing the null hypothesis of positive quadrant dependence (PQD) between two random variables. Such a testing problem is important since prior knowledge of PQD is a qualitative restriction that should be taken into account in further statistical analysis, for example, when choosing an appropriate copula function to model the dependence structure. The key methodology of the proposed testing procedures consists of evaluating a “distance” between a nonparametric estimator of a copula and the independence copula, which serves as a reference case in the whole set of copulas having the PQD property. Choices of appropriate distances and nonparametric estimators of copula are discussed, and the proposed methods are compared with testing procedures based on bootstrap and multiplier techniques. The consistency of the testing procedures is established. In a simulation study the authors investigate the finite sample size and power performances of three types of test statistics, Kolmogorov–Smirnov, Cramér–von‐Mises, and Anderson–Darling statistics, together with several nonparametric estimators of a copula, including recently developed kernel type estimators. Finally, they apply the testing procedures on some real data. The Canadian Journal of Statistics 38: 555–581; 2010 © 2010 Statistical Society of Canada     

Rationales Effektivitätstraining als Coaching-Methode für Führungskräfte

The Rational Effectiveness Training (RET) had been developed on the basis of the therapy approach of REBT according to Albert Ellis. In the following article the author shows, that the RET corresponds to the criteria of a coaching method. In addition she recommends to attach importance to the interpersonal and systemic perspective. Considering as case study of a newly nominated supervisor the RET has been applied.     

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。
