狂便谈禅,悲还说梦--龚自珍佛教思想管窥

龚自珍堪称近代中国思想解放的精神先驱.当激进的改革要求遭受挫折后,龚自珍便将沉沉心事投向了佛学.佛学赋予的智慧和普渡众生的济世观念使龚自珍受益颇深,一方面既找到了一种崇高的精神依托,另一方面同样也可以借此学说以申张自己励志改革的决心.在龚自珍那里,佛学兼具理性与信仰的双重情感,它具有宗教性,但更是龚自珍批判礼教、倡导经世致用之学的理论渊源之一.而这一自佛学中吸取营养的学术风气后来渐至发扬光大,终于形成了一股强大的社会改良思潮,也开启了近代佛学的思辨之路.     

哈尼族村社祭司——咪谷

咪谷是哈尼族社会生活中重要角色人物。他既是自然属性的人,又是神灵的化身;他曾经既是行政首长,又是宗教祭司;他是做人的楷模,是村寨生活精神的象征,是人生价值的追求目标。本文阐述咪谷产生的历史背景及条件的基础上,阐明咪谷与莫批在哈尼族社会中地位和不同作用,提出了咪谷精神在当今构建和谐村社中具有重要的现实意义。     

咒语的本源、演变、基本特征以及与祷词、神谕的区别

巫术与神灵崇拜仪式中出现的仪式语言有咒语、祷词与神谕。在现代社会尚存的以民俗信仰为主的中国本土传统的宗教仪式中,三种仪式语言往往连用或混杂在一起,而咒语的情况最为复杂。原始形态的咒语源自巫术活动中的语言灵力崇拜,而在后世有各种与神灵崇拜相结合的形态。依照咒语形成的原理和基本特征,可以判别具体仪式中咒语的灵力构成形态。根据三种仪式语言的性质、特征的差异,以及所用词句的不同,可以将三者加以比较细致的区分,借此可以明了特定仪式的超自然力崇拜的具体状况。     

应当关注时间心理无意识的研究

随着心理无意识研究在记忆、学习和思维等领域的兴起,内隐时间认知也逐步成为时间心理学中的一个研究热点。本文分析了探究内隐时间认知的四种方法:分离范式、序列学习范式、表征动量范式和计时分布相关范式,指出内隐时间认知实验范式在无意识时间人格与社会心理学中的研究也是有相当前景的。     

The association between parents' ethnic socialization and positive and negative interethnic contact among majority and minority groups in China and the moderating role of essentialism

In a multiethnic country like China, ethnic membership is an important dimension of social construction, and interethnic contact is a necessary component of social interactions. Family is the context where ethnic socialization takes place and where parents play a relevant role. The present study focused on the Hui-Han interethnic context. Measures of perceived parent's ethnic socialization, interethnic contact, and essentialism were administrated to Hui minority (N = 560) and Han majority (N = 954) secondary students. Results indicated that parents' positive ethnic socialization (cultural socialization/pluralism, promotion of harmony) was associated with greater positive and lower negative contact, while negative ethnic socialization (preparation for bias, promotion of mistrust) had opposite effects. Essentialist views of ethnicity moderated the associations of perceived parents' positive ethnic socialization with positive contact: the association between positive ethnic socialization and positive contact was stronger among individuals with lower (vs. higher) essentialist views. Results did not differ across the majority and the minority group. Implications for prompting positive interethnic interactions and preventing negative contact are discussed.     

Numeral size, spacing between targets, and exposure time in discrimination by elderly people using an lcd monitor

The present study investigated the effects of numeral size, spacing between targets, and exposure time on the discrimination performance by elderly and younger people using a liquid crystal display screen. Analysis showed size of numerals significantly affected discrimination, which increased with increasing numeral size. Spacing between targets also had a significant effect on discrimination, i.e., the larger the space between numerals, the better their discrimination. When the spacing between numerals increased to 4 or 5 points, however, discrimination did not increase beyond that for 3-point spacing. Although performance increased with increasing exposure time, the difference in discrimination at an exposure time of 0.8 vs 1.0 sec. was not significant. The accuracy by the elderly group was less than that by younger subjects.     

Use of pirated compact discs on four college campuses: a perspective from theory of planned behavior

The Theory of Planned Behavior was chosen as the framework, assuming that college students are rational decision makers seeking to maximize economic gains in purchasing compact discs. A questionnaire was given to 450 students from four college campuses in the Kaohsiung area of Taiwan. Analyses showed that the more positively rated the Behavioral Intention toward purchasing pirated music compact discs, the more likely the college students were to purchase them. Conversely, when Subjective Norms and Perceived Behavioral Control were higher, college students were less likely to make a purchase. Therefore, buying pirated compact discs was consistent with the premises for Attitude, Subjective Norms, and Behavioral Control.     

"刑"与"直":礼法与情感——孔子究竟如何看待"证父攘羊"?

在伦理问题成为当今学术热点的背景下,围绕《论语》和《孟子》中的三个所谓“案例”(父与子相隐、舜窃父而逃、舜封弟于有庳)而展开的“儒家伦理争鸣”已经进行了好几年,然而至今没有结果。问题出在哪里呢?本文将通过对《论语》所载“父子相隐”问题的分析,提出自己的思考。这段记载如下:叶公语孔子曰:“吾党有直躬者,其父攘羊,而子证之。”孔子曰:“吾党之直者异于是。父为子隐,子为父隐,直在其中矣。”[1]这段记载是说:叶公以为“其父攘羊,其子证之”是“直”,而孔子指出“父为子隐,子为父隐”才是“直”。然而在近年的这场论战中,双方其…     

Cocaine-but not methamphetamine-associated memory requires de novo protein synthesis

Context-induced drug craving and continuous drug use manifest the critical roles of specific memory episodes associated with the drug use experiences. Drug-induced conditioned place preference (CPP) in C57BL/6J mouse model, in this regard, is an appropriate behavioral paradigm to study such drug use-associated memories. Requirement of protein synthesis in various forms of long-term memory formation and storage has been phylogenetically demonstrated. This study was undertaken to study the requirement of protein synthesis in the learning and memory aspect of the conditioned place preference induced by cocaine and methamphetamine, two abused drugs of choice in local area. Since pCREB has been documented as a candidate substrate for mediating the drug-induced neuroadaptation, the pCREB level in hippocampus, nucleus accumbens, and prefrontal cortex was examined for its potential participation in the formation of CPP caused by these psychostimulants. We found that cocaine (2.5 and 5.0 mg/kg/dose)-induced CPP was abolished by the pretreatment of anisomycin (50 mg/kg/dose), a protein synthesis inhibitor, whereas methamphetamine (0.5 or 1.0 mg/kg/dose)-induced CPP was not affected by the anisomycin pretreatment. Likewise, cocaine-induced CPP was mitigated by another protein synthesis inhibitor, cycloheximide (15 mg/kg/injection) pretreatment, whereas methamphetamine-induced CPP remained intact by such pretreatment. Moreover, anisomycin treatment 2h after each drug-place pairing disrupted the cocaine-induced CPP, whereas the same treatment did not affect methamphetamine-induced CPP. An increase of accumbal pCREB level was found to associate with the learning phase of cocaine, but not with the learning phase of methamphetamine. We further found that intraaccumbal CREB antisense oligodeoxynucleotide infusion diminished cocaine-induced CPP, whereas did not affect the methamphetamine-induced CPP. Taken together, these data suggest that protein synthesis and accumbal CREB phosphorylation are essential for the learning and consolidation of the cocaine-induced CPP, whereas methamphetamine-induced CPP may be unrelated to the synthesis of new proteins.     

Visual and haptic feedback contribute to tuning and online control during object manipulation

The authors employed a virtual environment to investigate how humans use haptic and visual feedback in a simple, rhythmic object-manipulation task. The authors hypothesized that feedback would help participants identify the appropriate resonant frequency and perform online control adjustments. The 1st test was whether sensory feedback is needed at all; the 2nd was whether the motor system combines visual and haptic feedback to improve performance. Task performance was quantified in terms of work performed on the virtual inertia, ability to identify the correct rhythm, and variability of movement. Strict feedforward control was found to be ineffective for this task, even when participants had previous knowledge of the rhythm. Participants (N = 11) performed far better when feedback was available (11 times more work, 2.2 times more precise frequency, 30% less variability; p < .05 for all 3 performance measures). Using sensory feedback, participants were able to rapidly identify 4 different spring-inertia systems without foreknowledge of the corresponding resonant frequencies. They performed over 20% more work with 24% less variability when provided with both visual and haptic feedback than they did with either feedback channel alone (p < .05), providing evidence that they integrated online sensory channels. Whereas feedforward control alone led to poor performance, feedback control led to fast tuning or calibration of control according to the resonant frequency of the object, and to better control of the rhythmic movement itself.
