对构建"两课"实践教学新模式的探讨

该文针对学分制管理后“两课”实践教学面临的新问题，提出要构建“两课”实践教学的新模式，必须继承原有实践教学中的好形式，必须对“两课”实践教学的组织管理、内容、形式及考核评估等进行重新研究。     

新世纪高职英语教学面临的问题和对策

高等职业教育作为我国高等教育的重要组成部分，高职英语教学必须突出对学生语言实际交际能力的培养。但目前的高职英语教学存在学生英语基础薄弱，教师授课任务繁重。教材建设缓慢等问题。搞好高职英语教学，需要我们从师资、教材、教学手段等过多方面下功夫。     

研究"后过渡期"特点促进中国经济稳定发展

入世后3年,中国的国民经济始终保持着平稳快速增长,对世界经济的影响力也在不断增强.2004年底到2006年底是中国入世的后过渡期.能否准确认识和把握后过渡期特点,能否从更大范围和更宽视野统筹国内发展和对外开放,能否充分运用WTO规则以趋利避害,提高应对市场开放冲击的有效性,关系中国能否顺利度过后过渡期,关系中国经济的长期繁荣稳定.

金融机构呼唤税负公平

自改革开放以来，为吸引外资，对进入我国金融市场的外资金融机构提供了一定程度的税收优惠政策。在加入世界贸易组织，实现金融领域的全面开放以后，如果不及时改变对外资金融机构倾斜的财税政策，将对我国民族金融业的发展产生不利影响。     

佛山市中心组团桥梁群对河道影响的数值分析

Modelling the effects of dam removal on migratory walleye (Sander vitreus) early life‐history stages

Many dams in the USA have outlived their intended purpose and an increasing number are being considered for removal. Yet, quantitative studies of the potential physical, biological and ecological responses are needed to assess dam removal decisions. In this paper, the responses of migratory walleye (Sander vitreus) to increased spawning habitat availability as a result of dam removal was studied by comparing scenarios with and without a high‐head dam in the Sandusky River (Ohio), a major tributary to Lake Erie. A conceptual, ecological model was proposed to define the relationship between hydrodynamics and walleye spawning, egg hatching, larval drift and survival. A mathematical, ecological model of the early life‐history stages was then developed and coupled with time series of depth and velocity predictions over the spawning grounds from a 1‐D hydrodynamic model. Model simulations were run for 1984–1993 for both the with‐ and without‐dam scenarios to assess the potential benefit of dam removal. The simulation results demonstrated that velocity, depth and water temperature are major factors influencing adult walleye spawning success. Without the dam, 10 times the amount of spawning habitat would be available for walleye to spawn. This increase in spawning habitat area resulted in up to five times the total egg deposition and seven times the larval output to the nursing grounds, based on the assumption that 5% of the walleye population of Lake Erie migrated up the Sandusky River to spawn. We concluded that the spawning habitat in the current condition (with the dam) is limiting and additional spawning habitat upstream could significantly increase the number of larval walleye drifting to Lake Erie. The model sensitivity analysis showed that the number of walleye migrating up the river in spring is the dominant factor for larval recruitment to the lake.
