论文化利益结构

文化利益结构是指一个社会(或国家)内部相互关联、相互作用的文化利益取得、分配、交换和消费的网络,是把文化利益单元联系为文化系统的桥梁和中介。文化利益结构包括主体、单元、中介等要素。凡是利益都与某种"权"相联系,因此应该用法律制度和道德约束规范权利。了解文化利益结构的特性,加强对文化产业的管理,合理分配、调整文化利益,对于国家的文化安全、文化发展乃至整个社会的发展,都具有重要的意义。

利益多元化语境下的食品安全规制研究--以利益博弈为视角

利益是社会发展的动力,利益机制理论是研究社会问题的一种重要方法。在食品安全领域中存在相关利益群体的利益对立和冲突,由此产生了生产者与消费者、监管者与生产者、生产者与销售者之间的利益博弈现象。我国既有食品安全治理模式是建立在一种单元化利益观主导基础上的政府主导型模式,这种模式存在忽略食品安全领域相关利益群体利益冲突和协调机制、淡化其利益产生和分配机制、缺乏利益表达和保障机制的局限,应当重构一种以多元利益观为导向的新型食品安全治理模式。

Williams-Otto Plant Control Based on Production Planning Associated to Coordinated Decentralized Optimization and Plantwide Control Techniques

Manufacturing plants are increasingly complex and integrated, requiring control systems able to identify the interactions between the various operating units. Production planning and control design of a process are tools that, if combined, bring many economic benefits to the processes since they aim to identify and maintain optimal decision operations to a system. This work uses such integration between production planning and plantwide control to propose a control system for the Williams-Otto plant from the definition of the operating optimal point for coordinated decentralized optimization, in which the original optimization problem decomposition into smaller coordinated problems ensure that the found local optimum also meets the requirements of the global system. The results for decentralized optimization are satisfactory and very similar to the global optimum problem and to the control system response proposed based on the optimal obtained. It is effective taking smooth actions, working with （economic） optimal set points （economically） of operation. The unification of production planning techniques and plantwide control techniques is an effective tool for the control system design for entire plants.
