战略性、科学性、协调性、操作性——“行为导控”视角下对县级国土空间总体规划的反思

分析县级国土空间总体规划实践困境,认为其根源在于以客观空间为对象的终极蓝图与计划解构式规划编制实施路径,难以适应规划作为各类行为导控依据并落实用途管制意图的改革初心。由此本文通过分析国土空间与行为互动的社会关系及动态过程内涵,在行为导控视角下提出协调用途秩序与活力、约束空间行为底线及适应动态实施的规划原则。在此基础上结合县级国土空间总体规划实践探讨面向行为导控的编制实施策略,包括支持引领行为方向的内容体系,规制行为底线的用途管制规则,以及适应行为过程的动态实施机制,以期规划在揭示空间使用规律的前提下,维系国土空间整体格局协调并为多元价值演绎提供路径与机会,体现战略性、科学性、协调性与操作性。

大数据时代成人泛在学习行为导控

大数据时代,泛在学习的基础环境得到进一步优化,这给成人求学者带来了更均等的自主学习机会。然而,由于成人学习者的动机适配度、约束力、认知策略等因素影响,不少人的学习效果不甚理想。为此,作为学习资源提供方,需要进行科学干预。激发高成就动机、培养兴趣、利用元认知监控,是心理导控的艺术;营造文化氛围、以小模块微学分促进学习惯性、以反转课堂助推知识内化,是业务导控的创新。

Flocking behavior with multiple leaders and global trajectory

Aiming at the group of autonomous agents consisting of multiple leader agents and multiple follower ones,a flocking behavior method with multiple leaders and a global trajectory was proposed.In this flocking method,the group leaders can attain the information of the global trajectory,while each follower can communicate with its neighbors and corresponding leader but does not have global knowledge.Being to a distributed control method,the proposed method firstly sets a movable imaginary point on the global trajectory to ensure that the center and average velocity of the leader agents satisfy the constraints of the global trajectory.Secondly,a two-stage strategy was proposed to make the whole group satisfy the constraints of the global trajectory.Moreover,the distance between the center of the group and the desired trajectory was analyzed in detail according to the number ratio of the followers to the leaders.In this way,on one hand,the agents of the group emerge a basic flocking behavior; on the other hand,the center of the group satisfies the constraints of global trajectory.Simulation results demonstrate the effectiveness of the proposed method.
