Structural Aspects of Differences in Income between Anglophones and Francophones*

Cet article compare les données publiées par Raynauld et al. concernant les différences dans le revenu entre les Français et les Anglais à l'aide de données récentes provenant d'une enquête sur échantillon. Il souligne plusieurs faiblesses méthodologiques de l'analyse de Raynauld. Une mise en parallèle des données recueillies en 1961 et en 1968 révèle un nivellement des différences dans le revenu durant cette période. Bien que le taux « national » du revenu moyen des francophones par rapport à celui des anglophones se rapproche de l'unité, les différences dans le revenu se sont accentuées chez les travailleurs au bas de l'échelle professionnelle. Cette conclusion ainsi que d'autres résultats permettent d'invoquer la « discrimination » comme étant un facteur influençant le niveau de revenu. This paper compares the data on French-British income differences presented by Raynauld et al. with more recent survey data. It mentions several methodological criticisms of Raynauld's analysis. Comparisons between data gathered in 1961 and 1968 indicate a levelling of the income differences during that period. Although the nation-wide ratio of francophone to anglophone incomes is now closer to unity, the income disparity has increased for persons in lower-skilled occupations. These and other findings invite various interpretations of “discrimination” as a variable related to income.     

On Conditional Correlation Coefficients of a Wold Markov Process of Gamma Intervals

In this paper we discuss the conditional correlations between two future intervals given the length of the current one in a Wold Markov process of Gamma intervals.     

A Multi-Faceted Response to an Adolescent's School Failure*

A family-based, multi-system intervention is described as a response to three years of an adolescent's school failure. In a case study describing an unmotivated family, unmotivated school, and systems-oriented helpers, an intervention plan is developed that is directed toward improving the adolescent's school behavior and performance. Family therapy occurred concurrently with those interventions. A family-trained psycho educational consultant is employed to mediate between family and school to avoid disturbing the integrity of the therapists relationship with the family. Short-term effects of these procedures are described.     

The self-image in the therapeutic dyad: A case example of mutual growth

The therapeutic relationship is seen as a mutual experiencing of self and other which is growth-promoting for the therapist as well as the patient. Work with a borderline woman during a period of two years evoked strong countertransference reactions in the therapist who, at times, experienced the patient as a mirror. A beginning sense of cohesion in the patient's highly fragmented sense of self found a parallel in this beginning therapist's developing professional identity.     

Jackknifing in Categorical Data Analysis

Estimation of nonlinear functions of a multinomial parameter vector is necessary in many categorical data problems. The first and second order jackknife are explored for the purpose of reduction of bias. The second order jackknife of a function g(.) of a multinomial parameter is shown to be asymptotically normal if all second order partials ?²g( p )?dp_i?p_j obey a Hölder condition with exponent α>1/2. Numerical results for the estimation of the log odds ratio in a 2times2 table demonstrate the efficiency of the jackknife method for reduction of mean-square-error and the construction of approximate confidence intervals.
