“BOT+TOD”轨道交通投融资模式初探——以佛山市地铁二号线为例

近年来,我国城市轨道交通进入快速发展阶段,城市轨道交通的快速发展需要巨大的资金支撑,传统城市轨道交通投融资方式已经难以为继。本文从城市轨道交通TOD发展模式出发,分析"BOT+TOD"投融资模式的特点及其总体方案,并且以佛山市地铁二号线为例,提出"BOT+TOD"的具体实施路径与操作方法,为市政公用基础设施投融资体制改革、创新轨道交通投融资模式、土地管理制度的改革提供借鉴。通过此创新投融资模式在我国城市轨道交通中的成功运用,改善融资困难局面,促进我国城市轨道交通持续快速发展。     

A VARIANCE-REDUCTION STRATEGY FOR RSM SIMULATION STUDIES

The application of optimization techniques in digital simulation experiments is frequently complicated by the presence of large experimental error variances. Two of the more widely accepted design strategies for the resolution of this problem include the assignment of common pseudorandom number streams and the assignment of antithetic pseudorandom number streams to the experimental points. When considered separately, however, each of these variance-reduction procedures has rather restrictive limitations. This paper examines the simultaneous use of these two techniques as a variance-reduction strategy in response surface methodology (RSM) analysis of simulation models. A simulation of an inventory system is used to illustrate the application and benefits of this assignment procedure, as well as the basic components of an RSM analysis.     

有限理性下的社保基金投资监管进化博弈研究

社保基金的投资监管是复杂的决策问题,无法满足主流博弈论“完全理性”的要求。因此从有限理性角度出发,分别建立了基金经理人之间、社保基金管理机构与基金经理人之间的进化博弈模型,求出模型的复制动态方程,研究不同情况下的进化稳定策略,并得到博弈群体的复制动态相位图。     

探因"贾岛现象"

在大诗人迭出的唐代,相形之下,贾岛的文学成就并不算高,但其对后世诗人的影响远远超出了其自身的成就.晚唐多种风格林立,但后人所称"晚唐体"却仅指贾岛一派诗风.北宋初九僧、林逋等隐逸诗人,南宋末永嘉四灵,明末竟陵派均宗师贾岛."贾岛现象"的浪底到底存在着怎样的动力源,竟能一次次地在文学史上掀起千层浪花?笔者试从贾岛生平、作诗态度、诗歌意境三方面进行论述,探究"贾岛现象"形成的原因.

公共支出绩效管理的国际比较与借鉴

提升公共支出绩效既体现了现代预算管理的变革趋势,又符合加强绩效管理的要求,是中国公共财政建设的改革方向。借鉴市场经济国家公共支出绩效管理的经验,需要结合具体国情,循序渐进地引入绩效管理的理念与制度框架,适时建立绩效评价结果与预算编制有机结合的预算约束机制。     

社会网络与女性职业性别隔离

社会学理论认为,人们的社会网络具有性别偏好,这导致了男女求职结果的性别分化,并部分地解释了职业的性别隔离问题。本文根据2009年8大城市调查数据,分析了我国城市女性的职业性别隔离在何等程度上受社会网络的影响。分析结果表明:8大城市在职者的社会网络具有性别同质化倾向,女性和男性更多地与同性亲朋交往;使用强关系成功求职的女性往往进入性别隔离的女性职业;使用弱关系成功求职的女性能摆脱职业性别隔离趋向,进入中性职业或男性职业。     

A Social Networks Approach to Public Relations on Twitter: Social Mediators and Mediated Public Relations

This study proposes theoretical and practical frameworks to systematically examine mediated public relations in social media spaces. We applied a social network conceptual framework to identify and characterize social mediators that connect the US State Department with its international public. The results showed that social mediators vary in terms of their formality and interdependence. Formal social mediators were primarily US government agencies while informal social mediators were nongovernmental organizations (NGOs) and individuals. Notably, relationships with populations in the Middle East and North Africa were mediated primarily by informal actors, and formal mediators played a key role in connecting the public with everywhere else in the world. Government-related formal mediators and informal social mediators showed similar levels of bilateral relationships. In contrast, news media, the most traditional public relations mediators, were rarely found as social mediators and demonstrated the most unilateral relationships.     

Electronic Play,Study, Communication,and Adolescent Achievement, 2003–2008

Adolescents’ time spent messaging, exploring websites, and studying on the computer increased between 2003 and 2008. Using data from the Panel Study of Income Dynamics Child Development Supplement, this study examines how such changes have influenced individual achievement and behavior from childhood to adolescence. Greater communications and Internet web time proved detrimental to vocabulary and reading whereas the increased use of computer games was associated with increased reading and problem‐solving scores, particularly for girls and minority children. Increased use of the computer for studying was associated with increased test scores for girls, but not boys. The consequences are more benign than many feared. Groups that have traditionally used the computer less (girls, minority children) appear to benefit from greater use.     

集体记忆与老字号的商道传承——以“义顺”商号为例

建号于1925年的“义顺”商号发展历程表明,老字号企业商道形成的过程也是老字号集体记忆内容的建构过程.老字号企业的集体记忆,既在社会环境中创造集体认同感,连接过去获得老字号商道的传承,又在群体的框架中去创新,重新建构老字号商道的时代性.老字号的商道传承,可以用集体记忆的时间机制实现商道的代际传递,用集体记忆的空间机制实现商道影响力的扩大,用集体记忆的升华机制实现商道从言行到制度、从制度到文化的转化,用集体记忆的强化机制不断重复商道,使得商道在实践中稳定延续和发展.
