Assessment of three-dimensional joint kinematics of the upper limb during simulated swimming using wearable inertial-magnetic measurement units

The analysis of the joint kinematics during swimming plays a fundamental role both in sports conditioning and in clinical contexts. Contrary to the traditional video analysis, wearable inertial-magnetic measurements units (IMMUs) allow to analyse both the underwater and aerial phases of the swimming stroke over the whole length of the swimming pool. Furthermore, the rapid calibration and short data processing required by IMMUs provide coaches and athletes with an immediate feedback on swimming kinematics during training. This study aimed to develop a protocol to assess the three-dimensional kinematics of the upper limbs during swimming using IMMUs. Kinematics were evaluated during simulated dry-land swimming trials performed in the laboratory by eight swimmers. A stereo-photogrammetric system was used as the gold standard. The results showed high coefficient of multiple correlation (CMC) values, with median (first–third quartile) of 0.97 (0.93–0.95) and 0.99 (0.97–0.99) for simulated front-crawl and breaststroke, respectively. Furthermore, the joint angles were estimated with an accuracy increasing from distal to proximal joints, with wrist indices showing median CMC values always higher than 0.90. The present findings represent an important step towards the practical use of technology based on IMMUs for the kinematic analysis of swimming in applied contexts.     

重庆第三产业R&D投入产出效应的实证研究

本文构建了二级三要素CES生产函数,把要素投入分为R&D投入与非R&D投入两个部分,计算了重庆第三产业五个主要行业的R&D投入与非R&D投入的替代弹性和产出弹性。研究发现这些行业目前都处于规模报酬递增阶段,人力投入与资本投入之间的替代弹性平均约为1,R&D资本投入替代弹性比R&D人力投入替代弹性小,非R&D投入的产出弹性高于R&D投入的产出弹性。最后根据研究结论提出了对策建议。     

关于生产函数的新思考——理论研究与实证分析

本文既考虑了本期投入对本期产出的影响，又考虑了过去累积形成的生产成果对本期产出的重要作用，并在此前提下建立一种新型生产函数-动态生产函数。运用动态生产函数与C-D生产函数对中国和中国部分省（区、市）的实证分析表明动态生产函数较符合中国和中国地区经济发展的实际。最后就各要素对产出增长率的贡献份额进行了测算。     

Determining factors in the success of R&D cooperative agreements between firms and research organizations

The purpose of this paper is to analyze the impact of a series of contextual and organizational factors on the success of 800 cooperative agreements between Spanish firms and research organizations, run between 1995 and 2000. Findings show that the most outstanding factors are, in the case of firms, commitment, previous links, definition of objectives and conflict, whereas for research organizations previous links, communication, commitment, trust and the partners’ reputation are more relevant. These study not only provides a comprehensive theoretical model to analyze the success of these agreements but is useful both for improving management of cooperation and for fostering collaboration both at a national an international level.     

Shareholder returns and the exploration-exploitation dilemma: R&D announcements by biotechnology firms

We explore a financial returns dimension of the exploration-exploitation dilemma. Using 1277 R&D announcements by 178 listed bio-pharmaceutical firms, we examine whether investors are myopic along the continuum of exploration (patenting and preclinical trials) to exploitation (human clinical trials and NDA). We find that investors respond positively at every stage, but there are differences between small and large firms. For small firms exploration is favored, provided it is focused. For large firms, there is value in both exploration and exploitation. Projects which are part of an alliance are no more likely to generate abnormal returns. Policy implications are discussed.
