- The reaction (p) over barp -> (Lambda) over bar Lambda -> (p) over bar pi(+)p pi(-) has been measured with high statistics at a beam momentum of p((p) over bar)=1.637GeV/c. The use of a transversely polarized frozen-spin target combined with the self-analyzing property of Lambda/(Lambda) over bar decay allows access to unprecedented information on the spin structure of the interaction. The most general spin-scattering matrix can be written in terms of 11 real parameters for each bin of scattering angle; each of these parameters is determined with reasonable precision. From these results, all conceivable spin correlations are determined with inherent self-consistency. Good agreement is found with the few previously existing measurements of spin observables in (p) over barp ->(Lambda) over bar Lambda near this energy. Existing theoretical models do not give good predictions for those spin observables that had not been previously measured.

- The purpose of this paper is to examine the aspects of being a physician that such medical professionals mention in dialogue groups when given the opportunity to choose their own topics of discussion.Design/methodology/approachOver a period of two years, 60 physicians participated in eight dialogue groups at one of the main hospitals in Stockholm, Sweden. Five focus group interviews were performed after the final dialogue group session.FindingsQualitative content analysis showed that three themes dominated in the physicians' perceptions of their role: hierarchy and subgroups; understanding of learning and knowledge; clinical work. Very little time in the dialogue groups was spent discussing the third theme, i.e. problems or issues related to patients or their families. The hierarchy among doctors seemed to influence many aspects of the role of these individuals, their healthcare organisation and their work environment. The methodology in the dialogue groups challenged the prevailing hierarchical structures and seemed to improve the relations between different groups of doctors in the hierarchy. For some of the physicians, this also resulted in a new way of perceiving and acting in their professional role.Research limitations/implicationsThe results of this study represent only one hospital.Practical implicationsThe findings may help healthcare managers understand physicians' conceptions of their role.Originality/valueFew intervention studies have considered management programmes directed towards physicians. The present investigation is the first qualitative analysis of the use of dialogue groups within a healthcare setting.
