基于Open Inventor的储层建模系统三维可视化研究

为更好地满足储层建模系统三维可视化改进的需求,在研究软件三维显示功能的基础上,针对原有软件的特点,提出一种将原先只使用OpenGL库进行三维显示的系统改造成利用Open Inventor库与OpenGL库共同实现三维绘制功能的软件思路和实现方法。分析和总结了使用Open Inventor调用OpenGL常见的几种技术。结合储层建模的一般原理,将测井数据和地震数据资料的计算和储层模型的可视化功能进行了分离。     

Co-production of Knowledge in Multi-stakeholder Processes: Analyzing Joint Experimentation as Social Learning

Purpose: Changing research design and methodologies regarding how researchers articulate with end-users of technology is an important consideration in developing sustainable agricultural practices. This paper analyzes a joint experiment as a multi-stakeholder process and contributes to understand how the way of organizing social learning affects stakeholders’ ownership of process outcomes. Design/Methodology/Approach:A learning group composed of the different stakeholders of the oil palm seed system in Benin was set around a joint experiment. We use a detailed account of the group dynamics to understand the social process. Findings: The way the process is designed and conducted has a great effect on the ownership by the participants. Methodological steps taken in this research process showed its efficacy to produce quick and positive feedback mechanisms. Stakeholders’ perspectives on what constitutes a quality oil palm seedling varied widely. Participants, mainly nursery holders, learned new production practices. Representatives of the research center learned a mismatch of recommendations with users’ contexts. Field observations further to the process indicate changes in practices among stakeholders that would be sustainable. Practical Implications: Beyond focusing on outcomes, initiatives in multi-stakeholder processes should also document and analyze social processes in order to better understand the mechanisms by which such processes foster socio-technical change, as well as identify potential institutional barriers to such processes. Originality/Value: Through a detailed analysis of group dynamics, this paper addresses an important knowledge gap in participatory agricultural development.     

王世懋研究回顾与展望

王世懋是明代中期一位具有多方面才能的文学家,目前对他的研究主要集中在诗歌理论、诗论思想及其评点本《世说新语》等方面。但他的诗文集仍未被整理,其年谱、交游考、著述考等文献学方面的工作,其时代、家世、地域与其诗学思想之间的关系,王世懋对胡应麟诗学思想的影响及其与前后七子、与公安派之间的关系,《艺圃撷余》在中国文学批评史上的真正价值,王世懋文学思想的界定等问题亟待解决。

Oil royalties and the provision of public education in Brazil

This paper examines how resource-based windfalls to Brazilian municipalities’ revenues affects their provision of education. Using within-municipality variation in per capita oil revenues transferred to municipalities, we find that receiving more oil royalties increases municipal education expenditures, which translates into more teachers, classrooms, and schools per capita. These effects are present only for municipally funded schools, implying that increased educational provision is due to better funding and not through increased demand for schooling. We also find, however, that some evidence that some types of school infrastructure and services may be affected by oil royalties, implying that this additional schooling coverage may be of lower quality. Interestingly, despite the increased provision of education student outcomes like the dropout rate worsen with higher oil royalties, although this may be due to changes in student composition.
