从"耳目"、"喉舌"到"向导"、"政监"——略论清末报人的办报理念与公众舆论的话语伦理

清朝末年,随着报刊业的发展和社会思潮的流转,报人对报刊的社会角色和功用提出了自己的理解,始曰“耳目”、“喉舌”,继之言“第四种族”与“舆论之母”,再则称“政监”与“向导”,愈转愈进,愈转愈激。由于立意于作为“政监”和“向导”,报刊特重“主观”之“言论”,遂由“代言”而逐渐转向“灌输”,甚至直接“制造舆论”。因此,尽管报人与报刊仍以代表“公意”、“公益”而自期,但主观之“言论”究竟在多大程度表达了“一般国民之公共意志”而于“民主政治”建设有所贡献,不免令人生疑。     

An automated test development of parallel tests from a seed test

Binary programming models are presented to generate parallel tests from an itembank. The parallel tests are created to match item for item an existing seed test and match user supplied taxonomic specifications. The taxonomic specifications may be either obtained from the seed test or from some other user requirement. An algorithm is presented along with computational results to indicate the overall efficiency of the process. Empirical findings based on an itembank for the Arithmetic Reasoning section of the Armed Services Vocational Aptitude Battery are given.The Office of Naval Research, Program in Cognitive Science, N00014-87-C-0696 partially supported the work of Douglas H.

广州大学生对衣服款式及颜色爱好特点的实验研究

本文采用心理物理学的等级排列法,用男女各16种服式及27种颜色布样做材料,随机抽取广州市五所大学一年级学生男女各30名为被试,对被试的服式爱好和颜色爱好特点进行实验研究,结果表明:(1)单纯对布样颜色爱好的顺序与对特定服式的颜色爱好顺序不一样、衣服款式不同,喜欢配搭的颜色的爱好等级顺序也不同。(2)当前男女大学生都喜欢活泼大方、文雅、有朝气的服装款式,而不喜欢过时的、古旧的服式。(3)从颜色明度来看,大学生喜欢明度大的(反射率Y大的)颜色,不喜欢明度小的(反射率Y小的)颜色。其颜色爱好变化趋势是从明度大的颜色向明度小的颜色方向变化。     

Acupuncture and emotion: the influence of acupuncture anesthesia on the sensory and emotional components of pain

Objective indices (heart rate, perspiration quantity, finger plethysmograph curves, and facial expression) and subjective indices (sensory and emotional subject reports) were recorded for 25 young Chinese adults (16 men, 9 women) during and after the simultaneous application of a strong pain stimulus and either foot classical (alloneural points Tsusanli and Yanglingchuan) or hand classical (alloneural points Hegu and Neiguan) acupuncture. Both forms of acupuncture were equally effective, showing that stimulation of the same nerve is not essential for pain relief. Acupuncture assuaged the emotional, but not the sensory, response to the painful stimulation.     

Acomparison of the musical scales of the ancient Chinese bronze bell ensemble and the modern bamboo flute

We compare over a two-octave range the tonal, interval, and scale relationships of an ancient Chinese bell ensemble of the Zhou Dynasty and a modern bamboo flute. By using subjective pitches, a tonal system with simple harmonic partials (the flute) could be compared with a tonal system with complex inharmonic partials (the bell). We argue that the underlying musical scales of the bell ensemble and the flute are closely related and lie between an unequal-interval pure-system scale and the just-intonation scale. There is some evidence that a least interval of 60 or 66 cents figures in the flute scale, that both flute and bell scales include a 90-cent interval and a true (1,200-cent) octave, and that neither scale includes a 100-cent interval. Since there is a true octave, the scales cannot be cycles of fifths, and since there is no equal-temperament half-tone (100 cents), the scales cannot be equal in temperament. We conclude that the flute and Zhou bell scales are very similar if not the same. Apparently, strong cultural traditions and human perceptual constancies united to sustain a common flexible musical scale during 2,400 years.     

内侧前额皮层-伏隔核环路在决策冲动中的作用：基于动物模型的研究

注意缺陷多动障碍(attentiondeficit/hyperactivitydisorder,ADHD)行为控制不足与决策冲动密切相关,后者受内侧前额皮层(medial prefrontal cortex, mPFC)与伏隔核(nucleus accumbens, NAc)调节。为调查ADHD决策冲动与m PFC-NAc间功能耦合的关系,研究采用ADHD模型SHR (spontaneously hypertensive rat, SHR)大鼠,结合延迟折扣任务和在体电生理,研究发现,与对照Wistar (WIS)大鼠相比, SHR大鼠对延迟大奖赏的选择百分比降低; WIS大鼠m PFC-NAc的Theta频段相干值表现为延迟选择时显著大于立即选择时、首次选择时大于连续选择时、转换试次时大于连续试次时,而SHR大鼠在上述条件均低于WIS大鼠。回归分析发现m PFC-NAc的相干差值与延迟大奖赏选择率显著正相关。结果表明m PFC-NAc间功能联系减弱是ADHD决策冲动缺陷的重要环路基础,该缺陷与其深度信息加工以及策略转换能力受损有关,扩展了ADHD决策冲动的认知和神经机制的认识。     

Fragile promise: The role of justification in promise-breaking

People who consider themselves moral sometimes use self-serving justifications to rationalize their selfish behaviours. Previous studies have tested the role of ambiguity in justifying wrongdoings, but it remains unclear whether ambiguity also plays a role in justifying promise-breaking behaviour and whether heterogeneity exists. To investigate justification in promise-breaking, we introduced a new experimental paradigm called the card-guessing task and used hierarchical cluster analysis to classify participants based on their promise-breaking decisions in unambiguous and ambiguous conditions. Experiment 1 revealed three clusters of solutions: Cluster 1 always kept their promises (i.e., keepers); Cluster 2 only exploited the vague promises and broke their promises in the ambiguous condition (i.e., intermediates); Cluster 3 tended to take advantage of vague promises and broke their promises irrespective of ambiguity (i.e., breakers). Experiment 2 confirmed that participants in the three clusters differed in their norm-abiding preferences and social value orientations. Keepers were more altruistic and had a stronger sense of norm compliance than intermediates and breakers. In conclusion, our study demonstrates that self-serving justifications were more likely to be employed by people who are moderately sensitive to deviation from social norms, which has implications for strategic interventions and policy formulation concerning unethical behaviour.     

The temporal structure of spoken sentence comprehension in Chinese

Three experiments with 60 native Chinese speakers were conducted to examine the temporal structure of spoken sentence comprehension in Chinese. In the two sentence-gating experiments, listeners heard sentence fragments of various sizes, either successively or individually, and decided on the agent role of the sentence. In the agent-naming experiment, listeners repeated aloud the sentence agent upon hearing the sentence. Converging evidence was derived from these experiments indicating the usefulness of sentence gating in tapping into the temporal structure of comprehension and in evaluating listeners’ comprehension on the basis of partial information. Results from these experiments show that partial sentence information plays a very important role in Chinese sentence comprehension, and that Chinese listeners integrate incomplete and ungrammatical sentence fragments by reference to complete and grammatical models in the language. It is argued that these processing characteristics reflect properties of the Chinese language in which few morphological, grammatical, and syntactic constraints are placed on the relationships between sentence constituents.

The Role of Psychological Reactance in Drinking Following Alcohol Prevention Messages1

Two experiments tested whether a dogmatic alcohol prevention message may, by arousing psychological reactance (the motivation to reassert a threatened freedom) result in more subsequent alcohol consumption, compared to a neutral message. In Study 1, 535 college students received either a high-threat (dogmatic) or low-threat (neutral) message recommending either abstinence or controlled drinking. Results indicated that high-threat messages were rated more negatively and resulted in more drinking intentions compared to low threat. The negative effect of high threat on message ratings was most pronounced for habitually heavy drinkers and an abstinence-espousing message. In Study 2, under the guise of a “memory study,” 74 college students received either a high- or low-threat message recommending abstinence from alcohol. Then, under the guise of a “perception study,” all subjects participated in a taste-rating task in which their beer consumption was unobtrusively measured. Results indicated that the effect of high threat was most negative for male heavy drinkers, who drank significantly more beer compared to low-threat controls. These results suggest that the persuasive ability of alcohol prevention efforts depend to a considerable extent on the reactance-arousing properties of the materials and that dogmatic alcohol prevention materials may have counterproductive effects for some college students.
