This article looks at the ability of a relatively new technique, hybrid artificial neural networks (ANNs), to predict Japanese banking and firm failures. These models are compared with traditional statistical techniques and conventional ANN models. The results suggest that hybrid neural networks outperform all other models in predicting failure for one year prior to the event. This suggests that for researchers, policymakers, and others interested in early warning systems, the hybrid network may be a useful tool for predicting banking and firm failures. 相似文献

二元经济结构理论对解决我国三农问题的启示 总被引:1,自引:0,他引:1
高海清 《榆林高等专科学校学报》2004,14(2):63-64
西方发展经济学的二元经济结构理论认为:只有当农业部门的剩余劳动已全部由工业部门吸收之后,农业部门的工资水平才能提高。我国当前“三农”问题产生的最主要原因:是建国初期城乡二元经济结构的制度化产生的阻滞作用。借鉴西方该理论对解决我国当前“三农”问题是一重要启示。 相似文献

Representing knowledge: instances of management information 总被引:1,自引:0,他引:1
Against the backdrop of discussions about the 'Information Society', the 'Informational Economy' and the role of IT in realizing organizational change we examine how representations of 'organizational knowledge' are constructed and used in work settings. We do this through the explication of ethnographic materials that detail the realization and use of Management Information (MI) in a major UK retail bank undergoing massive organizational change. We focus in particular on explicating how existing metric information was drawn upon to construct a representation of the work of the bank for those involved in managing that work. Systems designers have been increasingly interested in offering ways of conceptualizing the problem of 'knowledge' with a view to embedding these properties in systems. In the quest to develop representations of procedural knowledge to support work we argue that it is first necessary to understand how representations are actually created and used in work to support existing work practices. 相似文献

In this paper we develop a segmentation scheme for digital images based upon an iterative binary coloring technique that takes into account changing behavior of adjacent pixels. The output is a hierarchical structure of images which allows a better understanding of complex images. In particular, we propose two algorithms that should be considered as image preprocessing techniques. 相似文献

This article investigates the theoretical and empirical properties of a true cost-of-living index under conditions of changing preferences. A family of true indexes is defined based on the notion of the current utility function. A particular index, based on the previous period's utility level, is then defined. Given this definition, a true cost-of-living index is computed based on a quadratic expenditure system estimated with quarterly data from 1960–1981. For empirical purposes, changes in preferences are represented by the linear habit formation hypothesis. This index is then compared with Paasche and Laspeyres indexes. The true cost-of-living index grows somewhat faster than either the Paasche or Laspeyres index. It also displays considerably more variability. 相似文献

The bioethics movement has long promulgated a model of ‘principled decision‐making’ in which ethical dilemmas and conflicts between various rights, interests, and ethical principles are central. In many respects this movement has had a laudatory impact on health care and on health professionals, but we will also argue that the bioethical model of ethical analysis has important limitations. The model's theoretical orientation is discontinuous with the training and skills of health professionals, the manner in which health professionals conceptualise and solve problems that arise in a clinical setting, and the time constraints inherent in most clinical situations. As such, the model is not readily applicable to much of the day‐to‐day work of clinicians and, in particular, to the routine ethical questions and situations that arise in caring for patients. What we suggest is that the bioethical model does not take into account that health care professionals, as part of their daily work, encounter and manage difficult, often conflictual situations and that they do so by bringing to bear conceptual frameworks and therapeutic techniques that have, embedded within them, the ethical values and goals of their own fields, as well as established ways of dealing with problems and addressing competing priorities. We further argue that from a systems perspective, the bioethical model and the pragmatic, problem‐focused ethical decision‐making of clinicians operate on different levels of complexity; whereas the former is especially appropriate for situations that resist consensus or that raise significant issues of public policy, the latter serves as an effective framework in less difficult or complex situations that can be moved effectively toward consensus and closure. 相似文献
