A derives grid-based model for simulation of pedestrian flow

We present a derived grid-based model for the simulation of pedestrian flow. Interactions among pedestrians are considered as the result of forces within a certain neighbourhood. Unlike the social force model, the forces here, as in Newtonian physics, are proportional to the inverse of the square of the distance. Despite the notion of neighbourhood and the underlying grid, this model differs from the existing cellular automaton (CA) models in that the pedestrians are treated as individuals. Bresenham's algorithm for line rastering is applied in the step calculation.     

对油膜滑动摩擦系数测量系统的研究

为了改变张力法中对静摩擦系数不易测量、滑轮对测量精度的影响和减少操作者的测量误差.该系统利用通电螺线管产生的均匀磁场,通电导体在磁场中受到的洛伦兹力与摩擦力相等做匀速运动的基本物理规律.通过光电测速技术,由AT89C52单片机来调节流入导体的电流强度,使被测物体达到匀速.同时计算出摩擦系数值,并且由字符液晶显示模块HD44780显示出来.该系统不但可以测量相对油膜滑动摩擦系数,而且可以测量油膜最大静摩擦系数,只要更换少量器件可以用于各种摩擦系数的测量.因此该系统有较大的实用价值.

资源和环保约束下中小企业发展循环经济探析--常熟市中小企业竞争力系列研究之二

随着资源性产品价格全面上涨和“民工荒”的出现,随着国内环保力度的加大和国际贸易中“绿色壁垒”的增多,常熟中小企业的成本竞争优势遇到了资源和环境的双重约束。发展循环经济既有利于企业节约资源,提升其经济效益和社会效益,又符合国内外消费者的消费态势,是摆脱资源和环境约束的必由之路。常熟应在微观、中观和宏观三个层面上推动中小企业循环经济的发展。

论死刑

死刑存废之争由来已久,立论点有十余种之多.死刑存置论者极力从死刑的威慑力来维护死刑的正当性,而死刑废止论者则以人权主义否定死刑的正当性.死刑的正当与否应有一个明确的结论.     

The political economy of post-secondary education: a comparison of British Columbia,Ontario and Québec

A policy sociology approach is taken to examine the connections between neo-liberalism, post-secondary provincial education (PSE) policy in Canada and the impact of those policies. Our thesis regarding the broad political economy of PSE is that over the last two decades the adoption of this ideology has been a major cause of some dramatic changes in these policies and has brought about a fundamental transformation of PSE in Canada. The discussion builds on a comparative, multiple, nested case study conducted at the provincial (Québec, Ontario and British Columbia) and national level. Through the analysis of key provincial and federal documents, the team concludes that five themes dominated the PSE policy-making process. These themes are Accessibility, Accountability, Marketization, Labour Force Development and Research and Development. In discussing these themes, we illustrate their impact on and within the three provincial PSE systems: BC, Ontario and Québec. In the conclusion, we place the changes in their political and economic contexts and explicate the intended and unintended consequences of these policy priorities. We argue that the pressure for access has led to the emergence of new institutional types, raising new questions about differentiation, mandate and identity and new lines of stratification. A trend toward vocationalism in the university sector has coincided with ‘academic drift’ in the community college sector, leading to convergences in programming and institutional functions across the system, as well as competition for resources, students, and external partners. Unprecedented demand has made education a viable industry, sustaining both a proliferation of private providers and a range of new entrepreneurial activities within public institutions. Levels and objectives of public funding have swung dramatically over the period. Public investments in PSE, in the form of capital grants and tuition subsidies, have alternately expanded and contracted, being at some times applied across the board and at others targeted to specific social groups or economic sectors. Likewise, policymakers have treated PSE at times as a mechanism for social inclusion and equality, at others as an instrument for labour force development, and at yet others as a market sector in its own right.

我国PPI波动的长期驱动力与短期驱动力——基于Gonzalo-Granger分解的分析

根据我国PPI的7项分类指数的月度数据,运用Gonzalo和Granger(1995)以及Darrat和Zhong(2002)提出的检验协整系统中的长期驱动力和短期驱动力的方法,从PPI分类指数的视角分析了我国工业品出厂价格指数波动的长期驱动力和短期驱动力。研究结果显示,全部3项生产资料的分类指数(采掘工业、原料工业、加工工业)以及一般日用品类和耐用消费品类分类指数是我国PPI波动的长期驱动力,生活资料中的食品类、衣着类和耐用消费品类分类指数是短期驱动力。     

人物·思想·时代——《蒋廷黻社会政治思想研究》读后

20世纪30、40年代中国社会出现了一批自由知识分子,他们对国际国内政局情势发表了自已的见解,特别是当时有一位特殊的历史人物——蒋廷黻,他起家于学术,兼跨行政、外交等诸般领域,相当程度上代表了当时一批自由知识分子的思想意向。在短短几十年间,这些博雅通达之士因应时势,成为民国政治舞台上军人集团外一支不容忽视的政治力量,在近代中国政治发展史上占据相当重要的地位。张玉龙博士的《蒋廷黻社会政治思想研究》的问世,某种程度上可以说是弥补了蒋廷黻学者从政以后的思想演变、政治实践及二者间的互动研究的缺陷。
