Identity, as a guiding concept for work and retirement decisions, is explored in the current study. Image theory suggests that actions that “fit” with the goals of the trajectory image are fundamental for maintaining a positive and consistent self-identity (Beach, 1998; Beach & Mitchell, 1987). Incompatibility is the mechanism that evaluates whether retiring or continued work provides sufficient “fit” with the goals one hopes to achieve. In the current study, the “fit” of the trajectory image with retirement and work was measured in 238 full-time employees. Consistent with image theory predictions, individuals' perception of the incompatibility between five personal goals, within the trajectory image, and the choices of working and retiring predicted 25% of their retirement intent. Further support for goal incompatibility as a decision criterion is provided by findings showing it yielded better prediction than an alternative model based on goal facilitation, and equal prediction to an alternative model based on cost/benefit. Overall, the results are consistent with image theory and expand on continuity theory's (Atchley, 1999) concept of identity as fundamental for predicting retirement intent.

Abstract Bayesian decision theory provides a simple formal elucidation of some of the ways that representation and representational abstraction are involved with, and exploit, both prediction and its rather distant cousin, predictive coding. Both model-free and model-based methods are involved.

The extracellular matrix (ECM) plays a critical role in directing cell behaviour and morphogenesis by regulating gene expression and nuclear organization. Using non-malignant (S1) human mammary epithelial cells (HMECs), it was previously shown that ECM-induced morphogenesis is accompanied by the redistribution of nuclear mitotic apparatus (NuMA) protein from a diffuse pattern in proliferating cells, to a multi-focal pattern as HMECs growth arrested and completed morphogenesis . A process taking 10 to 14 days.To further investigate the link between NuMA distribution and the growth stage of HMECs, we have investigated the distribution of NuMA in non-malignant S1 cells and their malignant, T4, counter-part using a novel model-based image analysis technique. This technique, based on a multi-scale Gaussian blur analysis (Figure 1), quantifies the size of punctate features in an image. Cells were cultured in the presence and absence of a reconstituted basement membrane (rBM) and imaged in 3D using confocal microscopy, for fluorescently labeled monoclonal antibodies to NuMA (fαNuMA) and fluorescently labeled total DNA.
