虚拟社区中的网络政治参与的“群体极化”

随着网络技术的飞速发展，虚拟社区已经成为一种人类的“另类空间”，为人类提供一个崭新的交流平台和交往环境。而由于网络的固有的特性，使得网民参与政治以群体主体的形式出现，并且在网络政治参与中表现出“群体极化”现象。群体极化对我国的政治文明建设具有双重影响，全面评价群体极化的影响，探索造成群体极化的深层原因，是引导网络政治群体理性参与政治的基础。引导网络政治群体参与政治，防范群体极化，必须采取综合的措施。     

论政治参与对落实以人为本的价值

在物理教学中构建学生"主动参与"的策略

教学过程应该是促进学生"自我发展"的变化过程.教学过程只有通过学习者本身的积极参与、内化、吸收才能实现.因此学生能否主动地参与成为教学成败的关键.

河套灌区粮食水足迹与虚拟水净输出时空演变

为了正确评价灌区内水资源使用对改善现有水资源管理的影响,文中引入水足迹与虚拟水概念,同时考虑降雨和灌溉用水,计算了1960—2008年内蒙古河套灌区粮食水足迹与虚拟水净输出量的时空变化,进一步评价了灌区水资源在区域内和区域间的分配.结果表明：1960—2008年河套灌区粮食水足迹由3.534×109m3减小为1.634×109m3,自2000年灌区粮食虚拟水净输出量呈下降态势,两者构成均以蓝水为主（90%）;空间分布上,河套灌区中部地区（杭后、临河和五原）的粮食水足迹和虚拟水净输出量较大,而其他地区（磴口和前旗）较小;1960—2008年,粮食生产用水在灌区用水总量中所占比例呈显著下降趋势,年均下降1.07%.粮食生产用水的大部分以虚拟形式输送到灌区外部,该比例近年有所降低,但2008年仍高达76.22%.未来河套灌区应注重绿水和蓝水资源利用效率的提高.该研究为灌区水资源管理宏观政策的制定和可持续发展的实现提供理论依据.

Stakeholder participation in the distribution of freshwater in the Netherlands

It is widely recognized that integrated approaches are required to manage our limited water resources in an effective and sustainable manner. In the Netherlands, this is mostly realized by organizing integrated spatial development processes. This paper presents a discussion in which the distribution of freshwater is integrated with spatial development in the southwestern Delta in the Netherlands. This discussion is characterized by uncertainty in knowledge and stakeholders with diverging perceptions. By actively involving these stakeholders in a process of problem structuring, it was possible to reach an agreement on the preferred direction for solutions. Problem-structuring involves that stakeholders actively participate in formulating the problem and its solutions. It is characterized by interaction between stakeholders and the integration of expert knowledge and stakeholder knowledge. Based on these practical experiences, we conclude that putting integrated water management into practice benefits from a problem-structuring approach. This enhances learning processes and contributes to the development of an agreed upon and valid knowledge base. As the context of such processes is highly dynamic, there is a need for transparent and adaptive process management.

Modeling net water requirements for wetlands in semi-arid regions

Wetlands in arid and semi-arid regions often experience water shortage problems due to interrupted water supply. Rapid population growth and economic development have caused deterioration or total destruction of many wetlands in such regions. Protection or restoration of these wetlands require a good understanding of the relationship between water supply and the soil wetness. This paper presents a model simulation study of such a relationship based on weather and soil data from Xi’an, China. The study area has an average annual precipitation of 600 mm and evaporation of 1200 mm. The simulation results showed that, to produce a certain wet condition, the required amount of water supply varied with recharging time due to different evapotranspiration rates. To maintain a consecutive water table depth within 30 cm (1) for 5% of the growing season, water requirements varied from 7 cm to 16 cm for different recharging months; (2) for 12.5% of the growing season, water requirement varied from 9 cm to 20 cm; and (3) for 25% of the growing season, water requirements varied from 13 cm to 27 cm. The highest water requirement occurred in summer when the air temperature is the highest of the year. Simulation results also showed that the timing of recharge not only has an important effect on the threshold water requirement, but also on the overall soil wetness of a year. Recharging at earlier time of the growing season produced longer wet periods, but the overall water table remained low during the rest of the growing season. Later inflow only influenced the water table for a small portion of the growing season, but it maintained a generally high water table in winter months and the early part of the next growing season.

The potential for farmer participation in irrigation system management

The management of most irrigation systems involves shared responsibility between one or more government agencies and farmers. Finding the optimal level of farmer management participation is an essential part of achieving optimal system performance. Two cases are discussed where farmers have been encouraged to play a more active management role with promising results. In the Gal Oya system in Sri Lanka, farmers manage the tertiary channels and also have a voice in managing the main system. In the Philippines, small systems have been turned over entirely to farmer management, while on large systems farmers manage the tertiary or secondary levels. A number of factors appear to be important in the management success of these irrigation systems including:

-the social environment,

-a manageable main system,

-a strong commitment by the irrigation agency,

-the use of community organizers, and

-construction tasks around which farmers can organize.

Greater farmer involvement in irrigation management can have both economic and social benefits. Economically there is evidence that farmers perform certain functions better than outside agencies can, and that both farmers and agencies perform their management tasks better when they feel a mutual responsibility for a common objective. Social benefits include the organizational skills that farmers learn and which may be useful in other activities, and a sense of self-respect and self-reliance. Though farmer participation requires a deliberate effort on the part of international and government agencies, as well as farmers, the benefits can be substantial.
