某建设场地永久高边坡处理方案比选及设计

在永久高边坡处理中,通过多方案比较及实际运行,验证了在边坡中部设置平台将1个高边坡分成2个较低边坡的处理方式能够达到降低实施难度(包括设计、施工及征地拆迁的难度)、更经济合理的目的,较好地解决了用地指标限制与边坡稳定的矛盾。     

铁塔制造企业新型OA系统的构想与设计思路

为了提高生产效率和管理水平,铁塔制造企业大多购进先进数控设备来提高生产效率,但其生产流程与工序设置受种种局限依然在走传统的路子,导致硬件投入没有得到合理的回报。文章从铁塔制造企业的实际需求出发,通过对当今行业设备及软件状况的了解与掌握,提出了整套OA系统的设计构想与解决办法,旨在通过引导企业建立一套有针对性的、统筹高效的OA系统,在不过分增加投资的情况下,最大限度地提高效率与收益。     

Long-run purchasing power parity revisited: a Monte Carlo simulation

The existence of long-run purchasing power parity (PPP) implies that a cointegration vector of nominal exchange rate, domestic price, and foreign price is expected regardless of using the Engle-Granger two-step method or Johansen maximum likelihood approach. However, this paper has found conflicting results: the Engle-Granger technique tends to reject the long-run PPP hypothesis whereas the Johansen method is generally supportive of long-run PPP. Via Monte Carlo simulations, the present paper finds that the Johansen approach has a bias toward supporting long-run PPP especially under the circumstances in which the assumption of normally or/and independently and identically distributed disturbance terms is violated.     

债权激励降低了银行系统性风险吗?

2008年国际金融危机后,中国银监会把债权激励作为银行业薪酬制度改革的重要方向.理论上讲,债权激励存在防范风险、稳定金融的作用;而现实中,债权激励是否降低了银行系统性风险,其影响机制如何?文章利用CoVaR方法,测度了中国上市银行的系统性风险,构建非观测效应面板模型分析了债权激励影响银行系统性风险的直接与间接效应.研究发现:(1)债权激励能够显著降低银行系统性风险,存在直接影响效应.(2)债权激励对银行系统性风险的间接影响效应有两种渠道:其一,通过缓解期限错配,弱化银行间借贷关联,抑制银行系统性风险;其二,提高非利息收入(尤其是手续费及佣金收入)占比,强化银行的收入稳定性,达到降低银行系统性风险的目的.而衍生金融工具对银行系统性风险的影响存在不确定性,原因在于监管部门和银行业对衍生金融工具的使用过于谨慎.文章的结论对于中国银行业薪酬激励方案改革、优化审慎监管方向、防范银行系统性风险具有重要的政策意义.     

高速公路隧道施工管理对于造价控制的影响探究

为了促进我国经济的进一步发展,我国政府进一步提高了高速公路的建设力度.为了保证高速公路隧道行业能够快速发展,就必须优化工程内容,其中把控好工程造价,不仅可以有效降低成本,提高经济效益,还可以极大地减少资源浪费,实现资源可持续发展和资源的合理配置.本文结合隧道工程造价控制现状,分析了高速公路隧道工程造价的影响因素,探讨了编制隧道造价的注意事项,为类似高速公路隧道工程造价管理提供参考.     

采取措施严把工程质量关

西方知识分子的困境和理论

西方在近代社会通过知识分子这个阶层强烈地发展了一种“批判的建设性”,即对社会的贡献通过批判的建设来体现。这样的传统。与中国传统的知识分子的特征有很大不同。在中国,圣王真正参与朝政之中,可以选择与朝廷合作;如果不能合作,他仍可以在民间跟君道配合。实现士大夫的政治理想;如果朝政的道义基础彻底崩溃。他们也可以成为抗议精神的领袖,参与政治的空间是非常宽广的。     

Poverty,population and environmental degradation in China

This article examines the relationship between poverty, population, and environmental degradation in China. Environmental conditions include water pollution, deforestation, destruction of grasslands, soil erosion, and salinization. The authors review China's success in controlling environmental degradation through leadership, environmental policies, and institutional capacity. Findings suggest that environmental progress is best achieved indirectly by poverty alleviation, market integration, and population control. Government policies were not very effective. Degradation occurs due to limited financial resources, poorly trained personnel, and political factors. Control of water pollution was instituted since the 1980s. The levels of pollutants have been reduced, but the type of pollutant determines the seriousness of impact. Water pollution is due to industrial wastes, agricultural run-off, and soil erosion. Since the 1970s, reforestation targets have not been met. Technical extension and monitoring of planting is not available in most areas, and private, profit seeking interests control acreage. Grassland destruction is due to deforestation, agricultural expansion, and overgrazing. Independent regional authorities have successfully managed pasture programs. Erosion is the most serious in Loess Plateau, the Red Soils area, the Northeast China Plain, and the Northwest Grasslands, which comprise 70% of total land area. In 1990, erosion control was practiced in 39% of eroded land area. Salinization has remained fairly constant. Environmental controls (direct regulation, planned recovery, and state-mandated technological improvements) are uneven. The main tool for environmental management is the State Environmental Protection Commission and its executive unit, SEPA. Problems stem from vague laws, lack of means of enforcement, lack of coordination of laws, and lack of standards, schedules, and other provisions in ordinances.
