Abstract
The application of the fast multipole method reduces the computational costs and the memory requirements of the boundary element method from O(N2) to approximately O(N). In this paper we present that the computational costs can be strongly shortened, when the multipole method is not only used for the solution of the system of linear equations but also for the field computation in arbitrary points.

Abstract
Purpose
The paper follows Jason Cope's (2011) vision of a holistic perspective on the failure-based learning process. By analyzing the research since Cope's first attempt, which is often fragmentary in nature, and providing novel empirical insights, the paper aims to draw a new comprehensive picture of all five phases of entrepreneurial learning and their interplay.
Design/methodology/approach
The study features an interpretative phenomenological analysis of in-depth interviews with 18 failed entrepreneurs. Findings are presented and discussed in line with experiential learning theory and Cope's conceptual framework of five interrelated learning timeframes spanning from the descent into failure until re-emergence.
Findings
The study reveals different patterns of how entrepreneurs experience failure, ranging from abrupt to gradual descent paths, different management and coping behaviors, and varying learning effects depending on the new professional setting (entrepreneurial vs non-entrepreneurial). Analyzing the entrepreneurs' experiences throughout the process shows different paths and connections between individual phases. Findings indicate that the learning timeframes may overlap, appear in different orders, loop, or (partly) stay absent, indicating that the individual learning process is even more dynamic and heterogeneous than hitherto known.
Originality/value
The paper contributes to the field of entrepreneurial learning from failure, advancing Cope's seminal work on the learning process and -contents by providing novel empirical insights and discussing them in the light of recent scientific findings. Since entrepreneurial learning from failure is a complex and dynamic process, using a holistic lens in the analysis contributes to a better understanding of this phenomenon as an integrated whole.

Abstract
If the fast multipole method (FMM) is applied in the context of the boundary element method, the efficiency and accuracy of the FMM is significantly influenced by the used hierarchical grouping scheme. Hence, in this paper, a new approach to the grouping scheme is presented to solve numerical examples with problem‐oriented meshes and higher order elements accurately and efficiently. Furthermore, with the proposed meshing strategies the efficiency of the FMM can be additionally controlled.

Abstract
In October 2008, a group of international scholars met at Hohentuebingen Castle, in Tuebingen, Germany, to discuss issues of international governance in education. At that time, governance as an analytical concept was just beginning to be more widely discussed in German educational science. These discussions were primarily in the context of new forms of organizational steering and with regards to a changing embeddedness of national education systems attributed to processes of globalization and fiscal austerity. In addition, a large interdisciplinary research project located at the University of Bremen, TranState, was already exerting considerable international influence with a decidedly comparative perspective on those areas of German educational science. However, in this early phase, the debate on international governance in education was limited and focused heavily on emerging theories of governance, among colleagues at the University of Tuebingen, both at the Institute of Education as well as in other parts of the faculty. To me, Frank-Olaf Radtke was the key person who had first drawn my attention to educational governance, and I was especially grateful for having had the opportunity to continue our previous exchanges in the context of the Tuebingen meeting.

Abstract
An application of a boundary element method to the solution of static field problems in closed domains is presented in this paper. The fully populated system matrix of the boundary element method is compressed with the fast multipole method. Two approaches of modified transformation techniques are compared and discussed in the context of boundary element methods to further reduce the computational costs of the fast multipole method. The efficiency of the fast multipole method with modified transformations is shown in two numerical examples.
