This paper offers an account of a process to build up relations of trust as a necessary condition for developing a new concept of auditing. The conceptual base of the discussion is centered upon the idea of managing complexity. Specifically, trust is observed not only as a form of reducing the complexity of our world relevant to each of us, but also as a most powerful amplifier of social complexity. In the paper the distinction is made between contextual trust and responsible trust. It is argued that responsible trust is necessary in order to accept diversity and increase the organization's performance in a demanding environment. This, in turn, suggests the necessity to move from hierarchical organizations to recursive organizations. The system in focus in this work was the Colombian State and, in particular, the National Audit Office of Colombia, which has begun a process to support the development of self-controlled organizational systems.  相似文献

This paper describes the process that was followed at the Colombian National Audit Office, during 3.5 years, to develop new auditing practices, called second-order auditing. The purpose of the second-order control is to detect possible faults in the internal control mechanisms of the audited entities. General and particular models for second-order audit are presented, along with a method to carry out this type of auditing. Finally, a particular application of second-order auditing carried out in a Colombian national institution is presented.  相似文献

审计评价的Agent系统问题,就是行为审计博弈方的最优对策问题,即审计服务双方对其收益最大化的管理与优化.因此,风险因素在审计收益管理中有着重要影响,当把风险因素引入审计评价系统,并设定评价为Agent模式后,审计资产所有者风险份额的相对控制会从外部推动审计服务与评价效能的提升,内部会启动提高审计资产所有者效率的动力机制,从而提高了评价系统活力.通过审计评价系统的Agent模型与优化调控审计绩效评价管理方向,有助于促进审计绩效的持续改善,更好地促进审计服务创新发展.  相似文献

This paper presents a conceptual framework for the systemic study of community organizations (COs) in contemporary societies. This framework is made up of two ideal-type models of COs. These models are structured around the notions of rights, social interaction, and the State. The first ideal-type model is based on a liberal conception of society, and the second model is grounded on communicative ethics as developed by Habermas for contemporary deliberative democracy. The relevance and limitations of such interpretive framework are discussed when a brief exploration on the social meaning of COs in Venezuela unveils grounds for further questioning about the role of COs in contemporary society.  相似文献

一类非线性系统的动态面二阶滑模控制   总被引:1,自引:0,他引:1  
针对一类具有非匹配不确定的严格反馈非线性系统,基于动态面控制和二阶滑模控制设计方法,进行一种新颖的状态反馈控制器设计,实现了不确定系统任意小的跟踪误差。动态面控制类似于反演设计,但其包含一系列低通滤波器;低通滤波器允许控制对象数学模型不可微,这样就避免了反演设计所存在的"膨胀项",减少了计算量,易于实现。同时,由于引入二阶滑模控制,消除了传统滑模控制(一阶滑模控制)存在的抖振现象,既增强了控制系统的鲁棒性,又提高了系统的控制精度。  相似文献

C. West Churchman and Humberto Maturana share similar cultural traditions involving frustrations with applying conventional systematic methods in domains of social systems design (Churchman) and neurobiology (Maturana). They have independently of each other developed a rich systemic framework of analysis based on a constructivist epistemology. But there appears to have been little correspondence between the two traditions. This paper explores six possible areas of congruence between the critical systemic perspective associated with Churchman and Maturanas autopoiesis. This initial sketch reveals possible ways forward in applying ideas of autopoiesis to our social world through a more constructive and adaptive conversation with the works of Churchman.  相似文献

为提高车辆的操纵稳定性,基于线性矩阵不等式方法(LMI)计了集成车辆前轮主动转向(AFS)与直接横摆力矩控制(DYC)的底盘鲁棒模型匹配控制器(R-MMC).由于反馈控制变量车身侧偏角在车辆行驶过程中很难测量,还设计了车身侧偏角滑模观测器(SMO).通过在Slalom和μ-split 极限工况下的仿真试验,验证了底盘集成控制器可以显著提高车辆的操纵稳定性和主动安全性,且滑模观测器在幅值和相位上都能准确跟踪车身侧偏角实际值.  相似文献

This paper sidesteps the usual starting points for debate about complexity and the philosophy of science, which tend to assume that science is primarily about observation. Instead, the starting point is intervention, defined as purposeful action by an agent to create change. While some authors suggest that intervention and observation are opposites, it is argued here that observation (as undertaken in science) should be viewed as just one type of intervention. We should therefore welcome scientific techniques of observation into a pluralistic set of intervention methods, alongside methods for exploring values, reflecting on subjective understandings, planning future activities, etc. However, there is a need to explicitly counter a possible pernicious interpretation of this argument: intervention could (erroneously) be viewed as flawlessly preplanned change based on accurate predictions of the consequences of action. This is the mechanistic worldview that systems thinking and complexity science seek to challenge. Therefore, having redefined scientific observation as intervention, the paper revisits insights from systems thinking and complexity to propose a methodology of systemic intervention. Some brief reflections are then provided on the wider social implications of this methodology.  相似文献

This paper presents a conceptual framework for using energy as a vehicle for holistic development to address: poverty, gender discrimination, community involvement in decision making on social, economic, and environmental issues. The approach is systemic and participatory ironically, energy is always seen or considered in fragmentation from other areas and as a technical subject, without considering it in less literal and more metaphorical terms as an end and means of communication. Energy should be seen holistically. Holism is based on a profound understanding of the interconnectedness of the various parts and their relationship to the whole. The point made in this paper is that, by adding energy to the development plan, we solve nothing unless we also consider community mobilization, participatory approaches, and the role of gender in development. Pradhan's research in Nepal has demonstrated that if one thinks of energy only in technical terms and development projects strive to provide more electricity, the interventions can paradoxically just add more drudgery to the lives of women, unless policies consider energy within the context of the whole social, political, economic, and environmental system. Energy provision is more than merely a technical intervention. Participation uses human energy and the creative energy of human beings in a different way. The heart of participatory development is co-creating (in the sense used by Reason, 1988, 2002) understanding based on communication that is generative in the sense used by Paulo Freire. Generative understanding provides a different kind of energy, based on resonance. So this is a play on words when we place energy in a technical sense and energy in a human sense at the center of development. Also, physicists would argue that energy needs to be considered far wore widely as a basis for communication and life. Some also argue that energy is the basis of all organic and inorganic matter in the universe; it is the communication across subatomic matter.  相似文献
