La pratique de la médiation thérapeutique en groupe par le modelage de la terre avec des personnes autistes et psychotiques met en évidence les modalités de constitution et du travail du médium malléable.Ce dernier permet, à travers l’acte de modeler au sein du cadre dispositif, une mise en forme des traces sensori-motrices (ou traces sensorielles), préalables à la constitution de l’image du corps.Le travail du médium malléable rend aussi compte des modalités de constitution de l’enveloppe psychique, tant sur un plan individuel que groupal.Les formes constituées mettent en avant le recours à des actes symboliques, que nous répertorions, témoins de l’état de constitution de l’enveloppe psychique. De la bidimensionnalité (identification adhésive) à l’espace tridimensionnel (identification projective), le sujet émiette la matière, la morcelle, coupe, sépare, rassemble, assemble et construit.Le travail du médium malléable et le mode d’utilisation du médium réactualisent le lien à l’objet primaire. Ils permettent aussi de focaliser les effets transféro-contre-transférentiels. La spécificité de l’intervention des thérapeutes (en cothérapie dans ce dispositif) concerne la mise en acte de leur propre sensorialité, à travers l’adresse d’une « interprétation modelante ». / Practising the therapeutics mediation in group by the modeling of the earth with autistics and psychotics persons underlines the modalities/mode of constitution of the “medium malleable” and the work that it allows.The latest makes possible, through the action of modeling within framework plan, a setting of sensori motor (or sensorial traces), prior to the composition of the body image.The work of the “medium malleable” keeps the forms of the psychological envelope, as an individual plan or as a group.The constituted shapes emphasize the resort to symbolic acts that can be listed, witnesses of the state of composition of the psychological envelope. From the bi-dimension (adhesive identification)/2 dimension measurement to the 3 dimension measurement (projective identification), the subject crumbles the material, divides it, breaks, separates, gathers, puts together and builds. The work of the “medium malleable” and its mode of use update the link to the primary object. They also allow focusing on the “transfero-contre-transférentiels” effects. The specificity of the therapists (in co therapy in this case) concerns the acting of their own sensoriality, through the faculty of a “modeling interpretation”.

In the light of present problems with stress related illness in organizations, often affecting women working in health care, the purpose of the current study was to examine proactive and malleable factors that could influence nurse’s perception of work stressors. Based on a model, self-efficacy and grouped organizational factors were examined as antecedents to the outcome of anxiety and stress via cognitive appraisals. The mediating role of the cognitive appraisals was further examined. The sample consists of 117 nurses and assistant nurses of which 112 were females working at a hospital in southern Sweden. The analyses were conducted with simple and multiple regressions. The result revealed that self-efficacy and the organizational factor together serve as antecedents to cognitive appraisals of stress, however, contrary to previous research, not to all appraisals. The mediating role of the cognitive appraisals showed that the harm appraisal mediate the relation between the organizational factor and the outcome of both anxiety and stress. The threat appraisal is found to partly mediate the relation between the organizational factor and the anxiety outcome as well as the stress outcome. The result further showed a none mediation role for the challenge appraisal between any of the antecedents and the outcomes, which suggest that the challenge appraisal do not serve as an underlying mechanism in either relationship. Other relations in the model are further shown and discussed in the study together with limitations, implications and suggestions of future research.

This doctoral thesis is focused on comparative stress strain analysis of a spinal segment with a malleable fixation device and a physiologic spinal segment. In its opening a research study from available sources is carried out. It covers the contemporary state of scientific studies in the given area, anatomy of individual components of the spine, material properties, ways and magnitudes of loadings and also the most common FE model used in similar problems solved. To create a model of geometry of a spinal segment CT scans of a spinal segment of a 38-year-old woman are used. Then they are subsequently used in the modeling software SolidWorks to create the model of geometry of two lumbar vertebras L4 - L5 and a malleable fixation device. Using the computational system ANSYS Workbench, the complete computational model of the spinal motional segment with a malleable fixation device is compiled, covering models of material, loading and bonds. On the basis of the computational solution of FEM models for different ways of loading, a stress-strain analysis is performed. To compare obtained results a detailed comparative analysis with the physiological spinal segment, the segment with the degenerated disc and the segment with applied "rigid" fixation device is carried out. Within the stress strain analysis of the spinal segment with malleable fixation device, an analysis of the magnitude of the strain intensity of spongious bone tissue around the implanted transpedicular screw, depending on the cord pretension of the malleable fixation device, is performed.
