Purpose: Based on a resulting typing model, this paper focuses on four types of leaders (Approachables on the sidelines, Distanced overseers, Realistic succeeders and Dedicated sensitives), who differ in the analytical core category of "development of awareness.", Design/methodology/approach: Internal team coaching is intended to strengthen leaders in the health care system. The Team Leader Coaching Programme (TLCP) was implemented as an internal coaching instrument at rehabilitation centers using a train-the-trainer format. Twenty-one team leaders were surveyed on their experience of the coaching process they implemented in their teams. The interviews were analyzed using the grounded theory method (GTM) as theoretically discussed by representatives of second-generation GTM (Charmaz, 2014)., Findings: Use of the TLCP proved to be an intervention for initiating and enhancing an awareness development process regarding team leaders' reflections on their own position and leadership role, regardless of their profession. This process was found to be a prerequisite for implementing the learned content. The typing model is discussed given current contextual conditions in the rehabilitation system and their connectivity in practice for integrating coaching elements into daily management., Originality/value: This article presents a typology of healthcare leaders. Thanks to the reconstructive approach using grounded theory methodology, this article presents an in-depth analysis of the implementation process of a coaching program. The findings are both connectable to applied leadership research and useable for further development of training and interventions to strengthen team leaders in clinical settings., (© Janna Katharina Küllenberg, Debora Niermann, Sonja Becker and Mirjam Körner.)

A new A(n)B(n)O(3n-2) homologous series of anion-deficient perovskites has been evidenced by preparation of the members with n = 5 (Pb(2.9)Ba(2.1)Fe(4)TiO(13)) and n = 6 (Pb(3.8)Bi(0.2)Ba(2)Fe(4.2)Ti(1.8)O(16)) in a single phase form. The crystal structures of these compounds were determined using a combination of transmission electron microscopy and X-ray and neutron powder diffraction (S.G. Ammm, a = 5.74313(7), b = 3.98402(4), c = 26.8378(4) Å, R(I) = 0.035, R(P) = 0.042 for Pb(2.9)Ba(2.1)Fe(4)TiO(13) and S.G. Imma, a = 5.7199(1), b = 3.97066(7), c = 32.5245(8) Å, R(I) = 0.032, R(P) = 0.037 for Pb(3.8)Bi(0.2)Ba(2)Fe(4.2)Ti(1.8)O(16)). The crystal structures of the A(n)B(n)O(3n-2) homologues are formed by slicing the perovskite structure with (101)(p) crystallographic shear (CS) planes. The shear planes remove a layer of oxygen atoms and displace the perovskite blocks with respect to each other by the 1/2[110](p) vector. The CS planes introduce edge-sharing connections of the transition metal-oxygen polyhedra at the interface between the perovskite blocks. This results in intrinsically frustrated magnetic couplings between the perovskite blocks due to a competition of the exchange interactions between the edge- and the corner-sharing metal-oxygen polyhedra. Despite the magnetic frustration, neutron powder diffraction and Mössbauer spectroscopy reveal that Pb(2.9)Ba(2.1)Fe(4)TiO(13) and Pb(3.8)Bi(0.2)Ba(2)Fe(4.2)Ti(1.8)O(16) are antiferromagnetically ordered below T(N) = 407 and 343 K, respectively. The Pb(2.9)Ba(2.1)Fe(4)TiO(13) and Pb(3.8)Bi(0.2)Ba(2)Fe(4.2)Ti(1.8)O(16) compounds are in a paraelectric state in the 5-300 K temperature range.
