Hydro-economic Modeling in River Basin Management: Implications and Applications for the European Water Framework Directive

Economic ideas and processes are becoming increasingly integrated with more traditional engineering and hydrologic models of water management problems. Combining economic management concepts and performance indicators with an engineering-level of understanding of a hydrologic system can provide results and insights more directly relevant for water management decisions and policies. When such models are developed and used with involvement of stakeholders, they can become a basis for shared understanding of water problems as a foundation for negotiated management and policy solutions. When implemented with optimization software, integrated hydro-economic models also can suggest promising innovative solutions for policy-makers to consider. Their applications to river basin management problems are reviewed. Economic and integrated economic-engineering-hydrologic modeling is then discussed in the context of the evolving European Water Framework Directive. Relevant items are cost recovery and water pricing, cost-effectiveness of water management measures, and public participation in decision processes.     

Scaffolded writing and rewriting in the discipline: A web-based reciprocal peer review system

This paper describes how SWoRD (scaffolded writing and rewriting in the discipline), a web-based reciprocal peer review system, supports writing practice, particularly for large content courses in which writing is considered critical but not feasibly included. To help students gain content knowledge as well as writing and reviewing skills, SWoRD supports the whole cycle of writing, reviews, back-reviews, and rewriting by scaffolding the journal publication process as its authentic practice model. In addition, SWoRD includes algorithms that compute individual reviewer’s review accuracy, which is in turn used to support the various drawbacks of reciprocal peer reviews (e.g., variation in motivation or ability of reviewers). Finally, this paper describes an empirical evaluation showing that the SWoRD approach is effective in improving writing quality in content classes.     

我院大学生吸烟调查分析

不良的生活方式和个人行为对健康是一种“自我制造的危害”。吸烟有害世人皆知,然而,近年来吸烟大军更表现为年青化、女性化的特点,青年大学生们吸烟也较普遍,烟草危害在吸烟者身上表现也很明显,已给国家造成极大的疾病负担;青年大学生吸烟还有漫延之势,必须积极开设健康教育,传授保健知识,让他们自己起来同不良的生活习惯作斗争,同时,还必须制定有效的行政干预措施,才能把吸烟带来的毒害控制在最小范围。

环境友好油层保护钻井液的研究及应用

针对江苏油田地层特性和地面生态环境具体情况开展了钻井液防塌性能、油层保护与环境保护的协同研究。在研制和筛选能满足环境保护要求的钻井液处理剂如润滑剂、降滤失剂和油层保护剂等的基础上,通过配方优化研制出了环境友好油层保护钻井液体系,并进行了防塌、油层保护、裂缝封堵等性能的室内评价。评价结果表明:该钻井液体系具有较强的抑制泥页岩膨胀和分散能力,渗透率恢复值大于85%,润滑性及滤失性好,而且无生物毒性,化学毒性低,易生物降解。应用该钻井液体系在江苏油田AF地区进行了现场试验,现场应用表明,该钻井液体系防塌性和油层保护效果好,各项环境指标达到农用污染标准,可直接排放,从源头控制了钻井液的污染,可进一步推广应用。

Undergraduate Summer Research in Structural Engineering

For the last seven years, a summer Research Experiences for Undergraduates site in structural engineering, funded by the National Science Foundation, has operated at the University of Alabama at Birmingham. During this time, 33 students from 22 colleges and universities have participated in the site. Participants are recruited nationally and have come from as far away as California and Puerto Rico. The program is intended to provide students interested in graduate studies with an introduction to research methods, and to provide students who will not continue their studies past a bachelor of science in civil engineering with a better understanding of how research provides the theoretical foundation of engineering practice. Students work individually with faculty on literature reviews, computer modeling, laboratory testing, and field research. Three students have researched structural failure case studies and the technical and ethical lessons to be learned from them. Participants also have the opportunity to tour construction sites and construction material manufacturers’ and fabricators’ facilities. During the past three years, an ethics seminar series has been added. At the end of the program, students prepare research papers and Web pages documenting their work and present their results to faculty, students, and other participants.     

The Importance of Shared Environment in Infant-Father Attachment: A Behavioral Genetic Study of the Attachment Q-Sort.

In this first behavior genetic study on infant-father attachment, we estimated genetic and environmental influences on infant-father attachment behaviors and on temperamental dependency, both assessed with the Attachment Q-Sort (AQS; B. E.Vaughn & E. Waters, 1990; E. Waters, 1995). Mothers of mono- and dizygotic twins (N = 56 pairs) sorted the AQS with a focus on the infant's behaviors in the presence of the father. Genetic modeling showed that attachment was largely explained by shared environmental (59%) and unique environmental (41%) factors. For dependency, genetic factors explained 66% of the variance, and unique environmental factors including measurement error explained 34%. Attachment to father appears to be, to a significant degree, a function of the environment that twins share. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
