We give a new approach to the failure of the Canonical Base Property (CBP) in the so far only known counterexample, produced by Hrushovski, Palacín and Pillay. For this purpose, we will give an alternative presentation of the counterexample as an additive cover of an algebraically closed field. We isolate two fundamental weakenings of the CBP, which already appeared in work of Chatzidakis and Moosa-Pillay and show that they do not hold in the counterexample. In order to do so, a study of imaginaries in additive covers is developed. As a by-product of the presentation, we observe that a pure binding-group-theoretic account of the CBP is unlikely.

This study performed a systematic literature review to examine existing and recommended CBT support for staff working within mental healthcare, who experienced occupational traumatization. The following questions were posed: (1) What are the effects of differing levels of occupational trauma on the individual and/or organization? (2) Are there any current CBT-specific models, or treatment pathways, aimed at supporting those experiencing the effects of occupational trauma? Conclusions showed the effects of occupational trauma are significant, varied and predominantly negative to both employees, and the organizations where they work. There were no CBT-specific models or pathways sourced to address occupational trauma; however, interventions were highlighted which may form parts of a larger pathway. Reviewed evidence suggests that development of a stepped CBT pathway for occupational trauma will be beneficial.

There is a paucity of research exploring the validity, reliability and impact on clinical outcome of Cognitive Behavioural Psychotherapy (CBP) case formulations. This review considers a variety of literature that relates to formulations and their use, it also draws on other types of psychotherapy where there appears to be a more established and robust research base. The literature review explores the research that has taken place within CBP and considers the themes that emerge from this research. Several themes were identified and these relate to decision-making and experience, specific guidelines to aid quality of formulations and a significant lack of understanding of clients' views on the formulation process and its outcome. It is unclear whether formulations do influence the successfulness of therapy. Recommendations are made as to what further research is needed and the form this should take.
