A-H键振动频率与原子价层轨道能

本文研究了原子价层轨道能与共价型分子氢化物中A-H键的振动频率v_(A-H)的关系,结果表明二者间有良好的线性关系,其计算式为: v_(A-H)=-a∑n_1E_1/∑n_1(A)+b (1) V_(A-H)=-c∑n_1E_1/∑n~(B)+d (2)利用上式计算的振动频率V_(A-H)值接近于文献值。从而验证了用韩长日方法计算电负性的合理性。

Cognitive and interpersonal abilities related to the primary activities of R&D managers

This study attempted to identify the primary activities performed by R&D managers at different supervisory levels, and the cognitive and interpersonal ability requirements that underlie these activities. A task inventory containing 244 managerial tasks was completed by 117 R&D managers in nine organizations. The 48 tasks which managers rated as having spent the most time were factor analyzed, resulting in the identification of three primary activities: project management, personnel supervision, and strategic planning. Furthermore, these activities varied with supervisory level, with R&D managers performing a wider range of these activities with the progression from first-line to upper-level management.Thirty R&D managers later rated the degree to which 19 cognitive and interpersonal abilities were required for performing these primary activities. Strategic planning was rated as requiring significantly higher levels of oral expression, logical reasoning, originality, fluency of ideas, oral defense, and resistance to premature judgement than was required for the other two primary activities. Personnel supervision required a higher level of social sensitivity than was required for the other two activities. Project management required high levels of information ordering, oral fact- finding ability, problem sensitivity, and oral and written comprehension. Implications of the findings for understanding R&D managerial performance and personnel staffing functions are discussed.     

海上救助公约的发展及其主要影响

1989年通过的国际救助公约对传统的“无效果无报酬”原则所作的例外规定,引起了海运界和贸易界的极大关注,从而导致某些国际规则和国内法的修订。本文运用比较的方法对海上救助公约的发展及其对英国劳氏标准救助契约、国际共同海损理算规则和我国海商法的影响作了论述,并且提出了我国当前海商法应作修改补充的几点建议。

高校合并对原医学院校学报的影响

高校合并将给合并前的原医学院校学报(以下简称学报)带来提高学术水平、扩大刊物影响力、增加稿源和扩展作者群的机会,但短期内学报刊名变更可能会影响检索系统数据库对其文献计量学参数的统计,也可能影响刊物的订阅.学报应抓住机遇,努力克服短期内的不利因素,不断提高刊载论文的学术水平,使学报越办越好.
