社会风险治理是社会治理的重要组成部分,增强基层政府社会风险治理能力是推进国家治理体系和治理能力现代化的一大关键。随着我国社会的进一步转型,社会风险呈现出虚拟化、网络化、联动化等新态势,它使得基层政府社会风险治理面临着新的挑战。因此,需要从流程优化的角度,对基层政府社会风险治理的机制与方式进行创新,从而提高基层政府社会风险治理的水平。  相似文献

对初始情境中受难者“陷困”功能的探讨,是“动物叙事”叙事语法研究中不容忽视的一环,其中贯穿了一个最为基础的叙事功能指向——“抉择之痛”。强调“动物与人”两类受难者角色在身体、心理抑或情感维度陷入某种矛盾与纠结的状态,并且彼此间时常呈现出一定的矛盾悖反性。这一角色身份由动物形象与人类形象分别或共同承担,均指向一种叙事伦理层面的现代境遇的表达。在题材范畴方面,这一功能指涉涵盖了家养类与野生类“动物叙事”各自的叙事范畴。其效力边际已不仅仅局限在单纯生态视域与人性指涉的层面,而是凸显现代语境下人类所面临的共通性的伦理困境:一种挥之不去的矛盾、困惑与不安的情感和心境的写照。  相似文献

《麦田里的守望者》是美国小说家塞林格(Jerome David Salinger)发表于1951年的长篇小说,也是他最负盛名的小说之一。本文从视点及叙述者的可靠性问题出发,探讨了《麦田里的守望者》中独特的叙事策略所产生的修辞效果。同时以分析小说中“反英雄”形象的塑造为切入点,展示出资本主义消费型社会对人性的异化和解构,从而引发读者对现代人生存困境的深刻反思。  相似文献

Abrupt changes often occur for environmental and financial time series. Most often, these changes are due to human intervention. Change point analysis is a statistical tool used to analyze sudden changes in observations along the time series. In this paper, we propose a Bayesian model for extreme values for environmental and economic datasets that present a typical change point behavior. The model proposed in this paper addresses the situation in which more than one change point can occur in a time series. By analyzing maxima, the distribution of each regime is a generalized extreme value distribution. In this model, the change points are unknown and considered parameters to be estimated. Simulations of extremes with two change points showed that the proposed algorithm can recover the true values of the parameters, in addition to detecting the true change points in different configurations. Also, the number of change points was a problem to be considered, and the Bayesian estimation can correctly identify the correct number of change points for each application. Environmental and financial data were analyzed and results showed the importance of considering the change point in the data and revealed that this change of regime brought about an increase in the return levels, increasing the number of floods in cities around the rivers. Stock market levels showed the necessity of a model with three different regimes.  相似文献

The term ‘end-to-end’ process management is now commonplace in the language and practice of operations. Managers are encouraged to migrate from functional process management to end-to-end process management to realise a range of performance improvements. However, these improvements are often elusive; the specific challenges associated with such a migration are under-researched. This paper uses a cross-sector study to identify the challenges of end-to-end process management and to generate practical managerial guidance. Three areas are identified that demand particular managerial attention: the need to move beyond process mapping, the role of IT in process management and maintaining the process infrastructure as a strategic asset. More significantly, the findings highlight the need for greater conceptual clarity regarding the end-to-end concept itself. The existing literature suggests that scope is the primary differentiator of the end-to-end process – the requirement to manage an extended boundary from customer order through to customer fulfilment. However, this research suggests that the end-to-end concept is more complex, comprising of three core constructs with seven dimensions: scope (boundary conditions, sequence/flow and controls); scale (resources and input/output transformation) and complexity (interrelationships and orientation). End-to-end process management involves much more than an extended boundary. It requires a systemic perspective and clarity regarding controls and transforming resources.  相似文献

Optimal scheduling of shopfloor activities in an environment of discrete part manufacturing is discussed. The scheduling problem is a well known NP complete one. The main part, the sequencing problem, has been tackled using two techniques: virtual resources identification and taboo search heuristics. The first approach allowed the authors to reduce the complexity of the sequencing from a job shop to a general flow shop problem. On the other hand, the search for an optimal solution, with respect to a fixed strategy, has been achieved via the taboo search. A synthesis of the results of a large number of tests is presented as well as the results of an application to a real case. The latter is shown in comparison with the output of the system being presently used in the examined factory.  相似文献

In make‐to‐stock production systems finished goods are produced in anticipation of demand. By contrast, in stockless production systems finished goods are not produced until demand is observed. In this study we investigate the problem of designing a multi‐item manufacturing system, where there is both demand‐ and production‐related uncertainty, so that stockless operation will be optimal for all items. For the problem of interest, we focus on gaining an understanding of the effect of two design variables: (i) manufacturing speed—measured by the average manufacturing rate or, equivalently, the average unit manufacturing time, and (ii) manufacturing consistency—measured by the variation in unit manufacturing times. We establish conditions on these two variables that decision makers can use to design stockless production systems. Managerial implications of the conditions are also discussed.  相似文献
