Rhetorics and Realities in Public Service Organizations: Systemic Practice and Organizational Learning as Critically Reflexive Action Research (CRAR)

This article sets out to develop an argument and theory-in-practice related to organizational learning and systemic practice as critically reflexive action research (CRAR). It explores principles and concepts associated with CRAR, in the context of different emphases in understandings of and approaches to managing or working with change. The notion of epistemologies of practice is developed, as the basis for introducing on-site and off-site CRAR as interweaving cycles of managerial and organizational learning. A multilayered illustration of an improvisational CRAR environment, using principles of dialectical enquiry and critical learning theater, is offered. A diagrammatic analysis provides the framework for describing and reflecting critically on key CRAR processes. This is expanded with a consideration of possibilities for documentation that can assist with the validation of quality in CRAR processes and outcomes. This has relevance in the context of postpositivist action research at postgraduate levels or within project-based CRAR partnerships. This leads to a further discussion of principles and concepts, in the context of other literature and pressures on public services.     

MCHOKeM algorithm with assured bandwidth allocation in DiffServ networks

An active queue management (AQM) algorithm called MCHOKeM is presented, which is borrowed from CHOKeW that draws multi-packets at random from the buffer, the multi-packets are compared with an arriving packet and abandoned if they are from the same flow. But MCHOKeM uses multiple virtual queues for different priority packets and enhances the drawing function by adjusting the maximum number of draws based on the current status of virtual queue length. The number of parameters that MCHOKeM needs to maintain is determined by the number of priority levels being supported by the router, which usually has a small limited value. In order to explain the features of MCHOKeM, an analytical model is used. A series of simulation tests to evaluate the performance are given.     

基于多策略搜索的出租车服务仿真模型

为更细致、精确地描述出租车服务规律,提出一种依据历史信息和路网供求信息模拟出租车空车搜索行为的动态仿真模型,出租车根据以往的驾驶经验和对路网供求信息的掌握程度决定空车时如何寻找新乘客.仿真结果表明,向出租车提供路网供求信息不能有效提高出租车的空车效率,但有助于缩短乘客平均等待时间;依据平均历史信息的搜索策略能够有效提高空车效率.模型有助于城市交通管理部门更有效地规划和管理出租车运营系统,为其决策提供参考依据.     

Consumer Participation in Designing Community Based Consumer-Directed Disability Care: Lessons from a Participatory Action Research-Inspired Project

User participation has been embraced worldwide as a means to provide better consumer outcomes in health and community care. However, methodologies to achieve effective consumer engagement at the programme design level have remained under-explored. The purpose of this study was to evaluate the impact of a Participatory Action Research (PAR)-inspired methodology used to develop a consumer-directed community care/individualised funding service model for people with disabilities. A retrospective analysis of case notes and internal reports for the first 6 years of an ongoing project were examined. The findings suggest that PAR methodologies need to take into account community development, group support, and capacity building as well as succession planning and risk management issues in order to facilitate the often lengthy policy and project development process. Drawing on these findings, this article discusses five lessons and their methodological implications for PAR in a health or social policy/programme design context.
