基于哲学的幸福观思考

关于幸福的理解复杂多元,但对于"幸福是人的需求得到满足时的快乐感受和体验"这一点,是基本得到思想家们的共识的。根据幸福具有的主观性与客观性相统一的特点,幸福观并非一成不变,而是在不同的历史时期都是不同的,会随着社会变革而发生变化。所以,在现代文明日新月异的条件下我们要变革旧的、落后的幸福观,形成新的、先进的、适合于社会发展趋势、具有时代新特征的幸福观。当代社会新幸福观的哲学定位应是:物质幸福与精神幸福的统一;个人幸福与家庭幸福、社会整体幸福的统一;眼前幸福与长远幸福的统一;幸福目标与实现幸福手段的统一。

Understanding Recreational Boater Attitudes to Zoning in a Proposed Marine Protected Area

Although the success of marine protected areas (MPAs) and associated zoning schemes is largely dependent on stakeholder acceptance and support, there have been relatively few studies examining the response of recreational stakeholders to MPA proposals. This study investigates the response of recreational boaters to a proposed MPA in British Columbia, Canada. Using a structured questionnaire (n = 543) and a focus group (n = 6), the research examines the level of support for the concept of marine zoning and identifies key factors influencing support or opposition. Results indicate that a small majority of recreational boaters support the concept of marine zoning, but that there are areas of concern that ought to be addressed as MPA implementation proceeds. Support for zoning was strongly related to perceived benefits, particularly environmental benefits. Furthermore, perceived benefits overall were found to outweigh concerns as determinants of recreational boater support for zoning. Major dimensions of opposition included perceptions of over-regulation, loss of access for boating, and mistrust of the government. A suggestion is that such concerns may be mitigated through focused communication and meaningful involvement of boaters in the zoning process.     

Evaluating the effects of bus design on passenger flow: Is agent-based simulation a feasible approach?

In this paper, we propose an agent-based simulation approach that is capable of simulating the flow of passengers on board buses and at bus stops. The intention is that it will be applied during vehicle development to analyze how vehicle design affects passenger flow, and thus also how it affects system performance such as dwell time. In turn, this could aid the developers in making design decisions early in the development process. Besides introducing the simulation tool itself, the paper explores the realism of the data generated by the tool. A number of passenger flow experiments featuring a full-scale bus mockup and 50 participants were carried out. The setup of these experiments mirrored a number of ‘bus journeys’ (regarding vehicle design, number of passengers boarding/alighting at each stop and so on) that had previously been simulated using the simulation tool. When the data from the simulations were compared with the data from the passenger flow experiments, it could be concluded that the tool is indeed able to generate realistic passenger flows, although with some errors when a large number of passengers board/alight. The simulated dwell times were rationally affected by the tested bus layout aspects. It was concluded that the tool makes it possible to evaluate how variations in bus layouts affect passenger flow, providing data of sufficiently high quality to be useful in early phases of vehicle design.

基于GRNN的GSM-R场强覆盖预测算法

在比较Hata模型修正方法和GRNN算法场强覆盖预测效果的基础上,仿真分析了训练集构成和平滑因子选择对GRNN算法预测效果的影响,给出了训练集构成和平滑因子选择的方法;提出了电波传播环境相似系数来表征GRNN模型在不同环境下的适用性。仿真结果表明,两种传播环境的相似系数越大,由一种环境下测试数据确定的GRNN在另一环境下的预测精度越高。     

综合管廊在中关村西区市政工程中的应用与展望

以中关村西区建设的综合管廊为例,总结并分析了综合管廊在市政工程中的应用与前景。在市政工程设计综合工作中,改变了传统的以重力流管线为主导的设计思路,提出了以管廊为主导,合理确定管廊内部空间分配,充分利用管廊内、外部空间的新思路。通过对重力流管线系统的优化调整,较好地解决了重力流管线与管廊平面位置和高程交叉的矛盾,提出的一些建设性意见均得到了一级土地开发商的认同和有关设计单位的采用。通过对中关村西区建设综合管廊的思考,还对如何发展北京综合管廊事业提出了一些建议。
