We present a generalization of Daniel Nagin’s finite mixture model that allows non parallel trajectories for different values of covariates. We investigate some mathematical properties of this model and illustrate its use by giving typical salary curves for the employees in the private sector in Luxembourg between 1981 and 2006, as a function of their gender, as well as of Luxembourg’s gross domestic product (GDP).

Aim Recent research results in clinical psychology, health psychology and neurobiology underline the relationship between dissociative states, complex posttraumatic syndromes and borderline functioning [11]. Our study is meant to investigate the traumatic hypothesis of borderline functioning and to develop appropriate psychotherapeutic measures based on artistic mediations. Material and Methods.To estimate the effect of traumatic events, from the beginning of life up to recent stressors, linked to natural catastrophes, war, political persecution and migration, we undertook an integrated clinical and experimental study with a sample of 73 refugees and asylum seekers. In a second stage, those who suffered from PTSD or complex post-traumatic states were offered to attend arts psychotherapeutic sessions.. To investigate the personality functioning at the structural level, we used a mixed quantitative and qualitative methodology, combining a semi-structured biographical interview, a projective test, i.e. the Sentences Completion Test, for which we developed a new manner of interpretation , and psychometric scales, i.e. the HADS and the Index of Wellbeing . Furthermore, we analysed the artistic production (pictures, stories written under musical induction) with the help of rating scales constructed in the phenomenological and structural tradition. Results. With the help of non parametric multidimensional statistics, we extracted two profiles of personality functioning, linked either to repeated breaks, negligence and maltreatment from the beginning of life, or either to a recent external catastrophe, interrupting a continuous life course. Through the evaluation of the arts therapeutic sessions, we could note the first signs of resumption of the blocked process of subjectivation. Discussion.The results of the study support the traumatogenic hypothesis of borderline functioning, as well as current clinical considerations concerning the defensive role of dissociation in complex posttraumatic states. Conclusion. The study opens tracks for future research concerning an in depth investigation of the arts therapeutic process with traumatized people. [less ▲]

In this research project, we describe an application of statistical shape analysis. In order to differentiate the various kidney tumours appearing in childhood we use shape analysis on two-dimensional magnetic resonance images (MRI). We show that this mathematical procedure can be an interesting tool to assist the radiologist who is required to make a decision based on their intuition and their experience in lack of specific tumour characteristics. This study is the first one using MR images in oncology for statistical shape analysis. Our method is innovative in the way to find suitable landmarks and to test the differences, even if the sample size is small. In order to test the mean shape, the statistical test of Ziezold is used.
