非英语专业学生课堂生态位信念的实证研究

信息技术化的大学英语教学成为高校教育新的教学范式,这种范式的教学实践,打破了课堂生态系统的平衡。课堂生态系统中有三个基本因素:学生、信息技术及教师。根据生态位理论,采用定性与定量相结合的方法研究学生课堂生态位信念,并用spss16.0软件对所得数据进行分析。研究表明:学生作为课堂资源有效利用者的角色信念最高;学习过程表现者及课堂活动参与者的角色信念较高,学习策略使用者及自主学习者的角色信念处于中等水平;学生希望成为课堂信息流动的核心和积极能量的传递和转化者,但在信息流动和情感支持上对教师存在很大依赖性。     

Learning from Ecosystem-Based Management in Practice

We explore how marine ecosystem–based management (EBM) is translated from theory to practice at six sites with varying ecological and institutional contexts. Based on these case studies, we report on the goals, strategies, and outcomes of each project and what we can learn from these efforts to guide future implementation and assessment. In particular, we focus on how projects dealt with the challenges of working across geographic scales and diverse governance arrangements. While we hypothesized that EBM in the United States would be distinct from EBM in developing countries due to differences in social and political factors, we found that sites faced similar challenges. Variation among sites appeared to be more closely related to the preexisting management context and the scale at which the projects began rather than to clear differences between the United States and developing country contexts. EBM project implementers were able to overcome many of these challenges by focusing on a limited number of specific objectives, starting at a small scale, pursuing adaptive management, and monitoring a diverse set of indicators. These findings are directly relevant to current and future EBM efforts in these and other places.     

Modelling the spatial and temporal variability of the Cretan Sea ecosystem

The ecosystem function of the oligotrophic Cretan Sea is explored through the development and application of a 3D ecological model. The simulation system comprises of two on-line coupled submodels: the 3D Princeton Ocean Model (POM) and the 1D European Regional Seas Ecosystem Model (ERSEM) adapted to the Cretan Sea. For the tuning and initialisation of the ecosystem parameters, the 1D version of the biogeochemical model is used.After a model spin up period of 10 years to reach a quasi-steady state, the results from an annual simulation are presented. A cost function is used as validation method for the comparison of model results with field data. The estimated annual primary and bacteria production are found to be in the range of the reported values. Simulation results are in good agreement with in situ data illustrating the role of the physical processes in determining the evolution and variability of the ecosystem.     

Effective Policy Evaluation: Refining Design Processes for Coastal Ecosystem Condition Indicators

To achieve the desired outcomes of ecosystem-based or integrated coastal management, paradigm shifts must occur in all stages of the policy process. This article focuses on the evaluative stage following policy implementation, specifically on the use of coastal ecosystem condition indicators. A review of the recent literature suggests that coastal ecosystem condition indicators with too broad a scale or too narrow a scope lose utility and applicability. An analysis of these problems of scale and scope reveals that the process through which an index is designed and selected can hinder or heighten its validity. Local and diverse stakeholder input can help to ameliorate weaknesses, increasing the evaluative validity of coastal ecosystem condition indicators.

Advancing Coastal Habitat Resiliency Through Landscape-Scale Assessment

Coastal areas are among the most biologically rich regions in the world. They provide tremendous benefit to people through ecological services like pollution filtration, carbon sequestration, and storm protection. However, human activity has decreased the ability of ecosystems to provide these services, and in many coastal areas, restoration is not as effective as it could be. Limited success is largely attributed to vague goals and a lack of holistic, science-informed planning. Quantifying coastal habitat health can aid in setting better restoration goals and lead to greater restoration success. The Long Island Sound Study National Estuary Program conducted the first comprehensive look at coastal habitat health for the Long Island Sound Estuary. In this study we also reviewed landscape-scale habitat assessment progress within other coastal programs. Results can be applied to establish ecosystem health-oriented goals that improve habitat function and resilience across coastal areas.
