乾卦六龙的天文科学含义新解

本文认为乾卦六爻爻辞所说的“六龙”各种状态是苍龙星在一个回归年中所运动的不同天象。这种天象的观测年代,过去的研究都根据秦汉“二月二,龙抬头”等记载认为是春秋秦汉的实际观测。我们认为,其观测年代至少应早于西周晚期以前的乾卦爻辞形成年代;并根据秦汉易学中“建子起乾龙”“九二当太簇之月”的文献记载、甲骨文中“正月见龙”的记载以及仰韶文化时期的“(恙)和御龙”蚌塑图有力地证实了六龙天象的观测年代当与五帝虞夏的年代相当。同时认为,六龙天象的观测是先民们创制“六龙季历”的天文基础．“六龙季历”则是在古老的易占系统中流传的“易以三百六十析为期”的、刨制于原始社会晚期的一种太阳历。     

员工被上司信任感的形成机制

员工感知到上级对自己的信任是成功建立上下级信任关系的重要前提。然而,学界和业界对员工被上司信任感的形成机制却知之甚少。符号互动理论与社会信息加工理论为深入探究员工被信任感产生的机理提供了理论视角。根据这两个理论,我们提出授权与培养这两种管理行为是影响员工被上司信任感产生的重要因素;授权与培养对员工被上司信任感影响的有效性依赖于员工的目标导向、上司的可信度以及团队焦虑水平;员工被上司信任感的产生会影响员工的忠诚与敬业奉献,影响程度受制于上司所面临的管理风险。

The distracting effect of material reward: An alternative explanation for the superior performance of reward groups in probability learning

To determine whether the distraction effect associated with material rewards in discrimination learning can account for the superior performance of reward groups in probability learning, the performance of 144 school children (preschool, second, and fifth grades) on a two-choice successive discrimination task was compared under three reinforcement conditions (material reward, marker, and knowledge of results). The two events in the task had different frequencies of occurrence, as in probability learning, yet they appeared in a constant order to make 100% payoff possible. The subjects in the reward and marker groups learned the task more slowly, and the nonlearners among them used stereotyped alternation patterns to a greater degree than subjects in the knowledge-of-results condition. These findings suggest that a distracting effect of material reward is present in probability learning and may explain the superior performance of reward groups typically found in probability learning studies.     

Concomitant changes in classically conditioned heart rate and corneoretinal potential discrimination in the rabbit (Oryctolagus cuniculus)

Corneoretinal Potential (CRP) and heart rate changes were measured in a series of differential classical conditioning experiments in which the directionality of the heart rate response was related to (a) CRP acquisition, and (b) the certainty or uncertainty of the stimulus situation. The results suggested that heart rate decelerations were associated with stimuli that predict upcoming aversive events, while heart rate accelerations were associated with asymptotic CRP responding late in conditioning. These findings were interpreted in terms of (a) changes in general somatic activity, and (b) the cue properties associated with CSs which predict aversive events.     

巴蜀易学源流考

巴蜀易学素有渊源,两汉为滥觞期,六朝为续传期.唐代为总结期,两宋为高峰期,元明以下则为流衍期.自两汉迄清末,历代巴蜀易学著作约有180余种;数量虽然不多,然特征却很鲜明,流派众多,“四道”毕备,其“尚辞”者则有苏轼之《苏氏易传》,“尚象”“尚变”者则有李鼎柞之《集解》、来知德之《集注》,其“尚占”者则如汉严遵,而尤以卜筮易、道家易源远流长.至于《易》《老》兼治者,则有严遵、扬雄;发明图书易者,则如陈抟、胡世安;其以佛陀解《易》者,则有苏轼、龙昌期.至于仿圣拟经,由扬雄开其先(撰《太玄》),而王长文(攫《通玄经》)、卫元嵩(《元苞》)诸人继其事,成为巴蜀易学之一大特色.后之治《易》《玄》,谈《图》《书》者,皆以蜀学发其轫.刘成炘曰:“易学在蜀(伊川语),如诗之有唐矣.”(《蜀学论》)信然.
