基于新型评估指标的厌氧反应器快速诊断方法

有效的在线过程诊断是实现厌氧水处理工艺稳定运行的必要手段。基于在线监测数据,通过整合反应器气相液相重要参数,建构了一对新型状态评估指标,稳定性指标S以及辅助指标a。评估指标可以对厌氧反应器状态进行全面定量的诊断,也可以对过程潜在不稳定性进行早期预警。通过对厌氧反应器进行多种类型冲击实验（有机负荷、HRT、温度和毒物）,测试了指标对各种冲击状态的响应,实验结果表明新型指标可以对反应器状态进行准确快速的在线诊断。作为诊断方法的核心,指标对厌氧工艺的过程评估具有高精度和高灵敏性,并且特别适用于智能化的在线诊断和自动控制。

破坏性地震发生后,快速高效地开展地震应急工作离不开地震应急技术的基础支撑。为进一步掌握我国地震应急技术现状,持续增强我国应急能力,通过梳理现阶段我国地震应急指挥、地震烈度调查与损失评估、地震现场流动监测3大技术系统,从技术构成、技术功能、存在问题等方面探讨我国现有地震应急技术。结果表明:现阶段我国的地震应急技术发展显著,但仍存在不足和薄弱环节,标准化、智能化、综合化或将成为新方向。     

Speaking up and moving up: How voice can enhance employees' social status

A central argument in the literature on employee voice is that speaking up at work carries image risk. Challenging this assumption, we propose that voice can in fact positively affect how employees are viewed by others, thereby enhancing their social status. Using theory on status attainment and the fundamental social perception dimensions of agency and communion, we suggest that employee voice will result in higher status evaluations by increasing the extent to which an employee is judged as confident/competent (agency) and other‐oriented/helpful (communion). We conducted a survey study and two experiments to test these hypotheses. The results supported our predictions. Employees who voiced were ascribed higher status than those who did not, and this effect was mediated by judgments of agency (in all three studies) and communion (in two studies). These results highlight the implications of voice behavior for status enhancement within organizations.     

Past, Status Quo and Future of China’s Territorial Planning

Since 1949, China has witnessed four development stages of territorial planning. （1） In the 1950s the territorial planning got its start. （2） From the 1960s to 1970s territorial planning declined. （3） From, the 1980s to 1990s the first major tide of territorial planning began. （4） From the end of the 1990s to recent times the new round of territorial planning is under deliberation. Since 1998, the Ministry of Land and Resources has carried out some related work, especially in organizing pilot projects, and early research on the new round of national territorial planning. According to the need for economic and social development and the current conditions in China, it is the appropriate for China to carry out the new round of territorial planning. However, the government should correctly consider the correlations between territorial planning and other plan- nings, and take appropriate development action, e.g. stressing main points for the basis of overall planning, building a territorial planning system that coordinate with national conditions, strengthening research on various supportive measures of territorial planning, summarizing and upgrading experiences obtained in pilot projects, strengthening international exchange and training talented personnel.

Using expert knowledge to support Endangered Species Act decision-making for data-deficient species

Many questions relevant to conservation decision-making are characterized by extreme uncertainty due to lack of empirical data and complexity of the underlying ecologic processes, leading to a rapid increase in the use of structured protocols to elicit expert knowledge. Published ecologic applications often employ a modified Delphi method, where experts provide judgments anonymously and mathematical aggregation techniques are used to combine judgments. The Sheffield elicitation framework (SHELF) differs in its behavioral approach to synthesizing individual judgments into a fully specified probability distribution for an unknown quantity. We used the SHELF protocol remotely to assess extinction risk of three subterranean aquatic species that are being considered for listing under the U.S. Endangered Species Act. We provided experts an empirical threat assessment for each known locality over a video conference and recorded judgments on the probability of population persistence over four generations with online submission forms and R-shiny apps available through the SHELF package. Despite large uncertainty for all populations, there were key differences between species’ risk of extirpation based on spatial variation in dominant threats, local land use and management practices, and species’ microhabitat. The resulting probability distributions provided decision makers with a full picture of uncertainty that was consistent with the probabilistic nature of risk assessments. Discussion among experts during SHELF's behavioral aggregation stage clearly documented dominant threats (e.g., development, timber harvest, animal agriculture, and cave visitation) and their interactions with local cave geology and species’ habitat. Our virtual implementation of the SHELF protocol demonstrated the flexibility of the approach for conservation applications operating on budgets and time lines that can limit in-person meetings of geographically dispersed experts.     

Present Development Situation of Transgenic Crops and Effect on Ecological Environment

In recent years, genetic engineering technology has been playing a great role in improving crops. As far as property is concerned, transgenic crops are mainly classified into three types. One is anti-herbicide crops; next is anti-disease and anti-insect pest transgenic crops. The third is high added-value transgenic crops, such as insulin tomatoes China has cultivated. We have successfully expressed hepatitis B virus surface antigen genes in tomatoes and potatoes. Besides, scientists have al…     

Auditing a flooded quarry prior to marina development

Development of a marina in a flooded brownstone quarry will require construction of a canal to the Connecticut River through an isthmus separating the two systems. An environmental audit over a 16-month period developed quantitative limnological data required by regulatory agencies. The deep quarry basin, protected by high sandstone walls, became strongly stratified in summer. Development of littoral vegetation in the quarry was prevented by the steep sides of the basin. Unusual characteristics of the manmade quarry basin, compared to most natural lakes in Connecticut, included a mean depth of 14 m, an intense thermocline, and negative heterograde oxygen profiles with metalimnetic minima. Alkalinity, conductivity, and nutrient levels differed significantly between the quarry and the river. Mean chlorophyll a concentrations in the two systems were similar, but the distribution of phytoplankton classes were quite different. The environmental audit, by comparing physical, chemical, and biological characteristics of the quarry to those of the river, allowed prediction of changes in trophic status when the two systems are joined.
