Communities of Practice (CoPs) are social learning systems that can be, to a certain extent, designed. Wenger (1998) proposes the following paradox; “ no community can fully design the learning of another, but at the same time, no community can fully design its own learning” (p:234). My interpretation of Wenger’s statement is that learning environments such as CoPs need to be facilitated in their learning processes, but not their specific design. Approaching CoPs this way allows for the design of interventions that facilitate learning processes within a CoP rather than regulate them. However, empirical studies on facilitating internal processes of CoPs are sparse – most work is anecdotal. This means that one needs to look to other fields for guidance in order to discover how to facilitate CoPs in their learning. This paper describes part of a larger research project that asks the question whether communities of practice can be instituted in higher professional educational organizations as an effective method to facilitate participant learning (professional development) and stimulate new knowledge creation in the service of the organization. Using a more pragmatic approach to cultivating CoPs (Ropes, 2007) opens the possibility to use different theoretical perspectives in order to find and ground interventions that can facilitate learning in CoPs and which are typically used in organizational development trajectories based on learning (de Caluwe & Vermaak, 2002). In this paper I look at how theories of human resource development, workplace learning and social constructivism conceptualize learning and what type of environments promote this. I then map out community of practice theory along these fields in order to come to a synthesized conceptual framework, which I will use to help understand what specific interventions can be used for designing CoPs. Finally I propose several interventions based on the work done here. The main question I consider here can be formulated as follows; ‘what insight can Human Resource Development theories, Workplace Learning theories and Social Constructivist learning theory give in order to design interventions that facilitate internal processes of communities of practice?’
In the midst of continuous health professions curriculum reforms, critical questions arise about the extent to which conceptual ideas are actually put into practice. Curricula are often not implemented as intended. An under-explored aspect that might play a role is governance. In light of major curriculum changes, we explored educators' perspectives of the role of governance in the process of translating curriculum goals and concepts into institutionalized curriculum change at micro-level (teacher-student). In three Dutch medical schools, 19 educators with a dual role (teacher and coordinator) were interviewed between March and May 2018, using the rich pictures method. We employed qualitative content analysis with inductive coding. Data collection occurred concurrently with data analysis. Different governance processes were mentioned, each with its own effects on the curriculum and organizational responses. In Institute 1, participants described an unclear governance structure, resulting in implementation chaos in which an abstract educational concept could not be fully realized. In Institute 2, participants described a top-down and strict governance structure contributing to relatively successful implementation of the educational concept. However it also led to demotivation of educators, who started rebelling to recover their perceived loss of freedom. In Institute 3, participants described a relatively fragmentized process granting a lot of freedom, which contributed to contentment and motivation but did not fully produce the intended changes. Our paper empirically illustrates the importance of governance in curriculum change. To advance curriculum change processes and improve their desired outcomes it seems important to define and explicate both hard and soft governance processes.

In this paper, the performance gain obtained by combining parallel peri- odic real-time processes is elaborated. In certain single-core mono-processor configurations, for example, embedded control systems in robotics comprising many short processes, process context switches may consume a considerable amount of the available processing power. For this reason, it can be advantageous to combine processes, to reduce the number of context switches and thereby increase the performance of the application. As we consider robotic applications only, often consisting of processes with identical periods, release times and deadlines, we restrict these configurations to periodic real-time processes executing on a single-core mono-processor. By graph-theoretical concepts and means, we provide necessary and sufficient conditions so that the number of context switches can be reduced by combining synchronising processes.
