Neighborhoods for Entailment

This paper presents a neighborhood semantics for logics of entailment. It begins with a minimal system Min that expresses the most fundamental assumptions about the entailment relation, and continues by examining various extensions that reflect further assumptions that might be made about entailment. This leads first to the logic B that is the basic relevant logic, and then to more powerful systems. All of these logics are proved to be sound and strongly complete. With B the neighborhood semantics meets the Routley–Meyer relational semantics for relevant logic; these connections are examined. The minimal and basic entailment logics are shown to have the finite model property, and hence to be decidable.     

小学生对情绪社会调节作用的理解

考察了小学二、四、六年级学生对情绪社会调节作用理解的特点.结果表明:小学生认为愤怒、悲伤和恐惧情绪标志着表达者不同的人际地位,会诱发接受者不同的情绪和后继行为:愤怒情绪标志着表达者的支配地位,会诱发出接受者的恐惧情绪和道歉认错行为;悲伤和恐惧标志着表达者的非支配地位,会诱发出接受者的悲伤情绪和目标恢复行为,恐惧情绪有时还会诱发接受者的高兴情绪.在对愤怒、悲伤和恐惧情绪反映表达者的社会目标的理解上,没有差异,都反映了表达者期待接受者采取目标恢复的社会行为.高年级学生在区分不同情绪表达的支配性以及诱发接受者的情绪上,存在着差别;低年级学生对接受者的后继行为的理解存在着差异.     

对体液免疫反应的条件反射性调节

以饮糖精水作为条件刺激(conditioned stimulus,CS),腹腔注射免疫抑制剂环磷酰胺作为非条件刺激(unconditioned stimulus,UCS)训练Wistar大鼠,3天后腹腔注射卵清蛋白(ovalbunfin,OVA)抗原,观察再次单独条件刺激对原发性体液免疫反应的作用。结果发现．一次CU-UCS结合训练导致CS组大鼠对再现糖精水产生厌恶反应,外周血中抗OVA-IgG抗体水平显著低于UCS组。两次CS-UCS结合训练并多次给予条件刺激后,CS组大鼠抗OVA-IgG的条件性免疫抑制效应与一次CS-UCS结合训练及再次给予一次条件刺激的反应类同。这些结果证明条件刺激增强了环磷酰胺对动物原发性体液免疫反应的抑制作用．这种条件性体液免疫抑制作用是相对稳定和有限度的,不易受条件反射建立参数的影响。     

特质线索对儿童情绪、行为判断与归因的影响

本研究探讨在不同的道德冲突情境中,线索及其与行为的匹配性对儿童行为预测、情绪推断及其归因的影响。结果表明：（1）7、8岁儿童在一定程度上具备了根据他人特质推测情绪的能力,但是他们还难以做出准确的解释;（2）儿童对亲社会情境和犯过情境存在不同的情绪判断与归因模式;（3）在他人特质与行为匹配的时间,儿童更容易根据他人的特质来推测其情绪反应;（4）在他人特质不良的情况下,儿童更容易根据特质来预测其行为;（5）儿童预测他人行为的能力优于对他人情绪的判断。     

精神分裂症患者的记忆损害

摘 要 目的 探讨精神分裂症患者记忆损害状况。方法 采用修正的加工分离记忆实验程序,分别测试精神分裂症患者和正常对照组的记忆能力。结果 （1）精神分裂症患者外显记忆功能存在广泛的缺陷,而内隐记忆功能缺陷只在概念驱动下的测验中出现。（2）以阳性症状为主的精神分裂症患者的外显记忆成绩均高于以阴性症状为主的精神分裂症患者。(3)阴性症状严重程度与外显记忆成绩呈显著负相关。结论 精神分裂症患者的内隐记忆功能相对完整,而外显记忆障碍在以阴性症状为主的精神分裂症患者尤为突出。

Genetic and Environmental Influences on Achievement Goal Orientations Shift with Age

Students engage in learning activities with different achievement goal orientations. Some students pursue learning for learning sake (i.e. mastery goal orientation), some are driven by gaining favourable judgement of their performance (i.e. performance approach goal orientation), and others focus on avoiding negative judgement (i.e. performance avoidance goal orientation). These goal orientations are linked with academic achievement, and troublingly, students report decreasing levels of goal orientations across the school years. However, little is known concerning the mechanisms that drive this decline. In a large (N = 891 twin pairs) cross‐sectional genetically informative sample (age = 8 to 22 years), we found that older students reported lower goal orientations. Then, we identified shifts in the magnitude of genetic and environmental variance in each goal orientation. For example, variance in mastery goal orientation was primarily associated with environmental factors during the elementary school years. As students entered high school, genetic influences increased, replacing shared environmental influences. Finally, we situated these findings in the larger nomological network by testing associations with psychological constructs (e.g. personality and cognitive ability) and contextual variables (e.g. parents, schools, and peers).

高层次医学影像技师培养与临床水平的提高

随着我国经济飞速发展,医疗技术日新月异,综合医院从国外引进的影像设备越来越先进,而影像技术人员普遍存在学历、职称偏低、知识结构老化等问题,高层次医学影像技术人才出现断层,限制了新技术的高级临床应用和开发。急需培养知识面宽、基础扎实、素质高、能力强的复合型、实用型影像专业技术人才。建议加强高层次医学影像技术人才的培养,以适应新时期综合医院医学发展对影像技术人才的要求。     

茅山炼师张绍英

江苏丹阳历史上释道人物很多.佛教中有法融者开创牛头禅宗而名闻天下;道教中有韦景昭、吴法通、汤志道、翟志颖四人先后入主茅山,并跻身上清派宗师之列.此外,北宋时还有一个丹阳籍高道,隐于茅山修炼而闻名遐迩,他就是宋仁宗屡诏不出的明真先生张绍英.     

中国慈善事业的发展与需要努力的方向——背景、意识、法制、机制

慈善事业是弘扬互助友爱精神和建设积极向上的伦理道德的最好途径与方式,具有缩小收入差距、化解社会矛盾、促进共享发展成果的不可替代的客观功效。中国的慈善事业面临着十分有利的时代背景,但同时也面临着慈善意识落后、法制建设滞后、慈善机制发育不良等诸多制约。因此,改良国民的慈善意识是发展中国慈善事业的基础工程,健全完善慈善法制是发展中国慈善事业的根本保证,促使慈善组织运行机制发育成熟则是发展中国慈善事业的关键所在。作者强调,构建和谐社会离不开慈善事业的发展,建立在互助友爱基础之上的各种慈善事业应当成为构建和谐社会的必要且重要的内容,慈善事业的大发展,将促使中国现代化强国之路走得更加文明、更加协调。
