Two elongatoolithid dinosaur eggs from the Upper Cretaceous of Ganzhou, Jiangxi Province and the embryonic skeletons they bear are described. They represent the first oviraptorosaurian eggs with embryonic skeletons in China and provide the first example that an oospecies can be correlated to certain dinosaur taxon/taxa. The two eggs are the same as the pair of the eggs inside a female oviraptorosaurian pelvis from the same horizon of the same area in both macro- and micro-structures of the egg shells, and can he referred to the oospecies, Macroolithus yaotunensis Zhao, 1975. The morphology of the preserved part of the embryonic skeletons indicates that they may have been laid by an oviraptorid, Heyuannia huangi from Guangdong Province or a closely related oviraptorosaurian, which may have been lived in the Ganzhou area too in the Late Cretaceous. The embryonic skeletons of the two eggs are not in the same developing stage. In one of the eggs, the postzygapophysis of the preserved vertebrae are well ossified, indicating that it was just hatched.

Linn and hsi show how computers, teachers, and peers can serve as learning partners--helping students build on their ideas and become lifelong science learners. They invite everyone interested in improving science education to build on their experiences, share insights on the Internet, and create instruction. Computers, Teachers, Peers: • offers case studies to bring the ideas of students learning science to life. •Join Sasha, Chris, Pat, and Lee as they try to make sense of experiments using computers to display data in real time;• • provides principles to help teachers improve their instruction, use technology better, and inspire more students to love science. •Find out how to use visualization tools, online discussion, and more to make science relevant;• • gives researchers and instructional designers a model for effective research and curriculum design. •Linn and hsi report that the partnership approach to research resulted in a 400% increase in student understanding of science;• • helps schools develop technology plans that continuously improve science instruction. •Find out how schools can design better ways to use technology for learning;• • describes a partnership inquiry process where science teachers, science education researchers, discipline specialists, and technologists consider each others''perspectives and jointly design instruction. •Boys and girls are equally successful in the resulting science courses;• and • features practical tools for learning and instruction, including''Points to Ponder''--to encourage reflection on the ideas in each chapter (partnership groups or classes might use the points as discussion starters or assignments), and''Ask Mr. K.''--an interview, in each chapter, with the classroom teacher who was a founding member of the CLP partnership (in these interviews Mr. K. adds insights from his own classroom experiences).

针对黄花菜采摘点识别定位求解困难,开发了一款基于双目视觉系统的黄花菜采摘机器人,从确定并联机械手尺寸参数到对黄花菜图像采摘点定位求解进行了研究。提出一种在自然场景下黄花菜视觉识别与采摘点定位方法,对黄花菜图像提取hsi空间分量S并采用迭代最佳阈值分割算法;将黄花菜生长趋势姿态分为两类,计算连通域最小外接矩形,确定不同生长姿态下的感兴趣区域;在区域内运用累计概率霍夫直线检测结合求解对应参考点点线最小距离约束,取线段离矩形框参考点距离最小的端点为采摘点。以晴天顺光、晴天背光和阴天光照条件下进行实验验证,结果表明可以为采摘机器人提供黄花菜采摘点精确坐标信息。

This study empirically examines the relationship between a firm＇s fulfilling of corporate social responsibility （CSR） and performance. We developed a CSR index （CSRI） to quantitatively evaluate CSR, which consists of four dimensions measuring a firm＇s contributions to the economy, society, environment, and corporate governance, respectively. With data from publicly-listed firms in Taiwan during the period of 2004--2009, results of quantile regression show that fulfilling CSR has a significantly positive impact on firm performance, and that the impact in a more profitable firm tends to be significantly greater than that in a less profitable firm. Specifically, when a firm is more profitable, its management would be more willing to implement CSR. The implication is that a firm could pursue better performance while serving as a good corporate citizen.
