信任倾向与主观参照对网上购物意向的影响

该研究对225名大学生、在职人员进行问卷调查,通过分层回归分析探讨了信任倾向与主观参照对网上购物意向的影响。结果表明:男性在职人员的信任倾向要显著大于男大学生的信任倾向,而对于女性,这种差异不显著。工作与否、性别、学历在信任倾向、主观参照以及网上购物意向上差异不显著。主观参照对网上购物意向的影响受到信任倾向的缓冲,相对于高信任倾向的人,低信任倾向人的网上购物意向更容易受到主观参照的影响。信任倾向和主观参照对网上购物意向都有显著影响,但主观参照的回归效应更大。     

CS-dependent response probability in an auditory masked-detection task: considerations based on models of Pavlovian conditioning.

Experimental studies were performed using a Pavlovian-conditioned eyeblink response to measure detection of a variable-sound-level tone (T) in a fixed-sound-level masking noise (N) in rabbits. Results showed an increase in the asymptotic probability of conditioned responses (CRs) to the reinforced TN trials and a decrease in the asymptotic rate of eyeblink responses to the non-reinforced N presentations as a function of the sound level of the T. These observations are consistent with expected behaviour in an auditory masked detection task, but they are not consistent with predictions from a traditional application of the Rescorla-Wagner or Pearce models of associative learning. To implement these models, one typically considers only the actual stimuli and reinforcement on each trial. We found that by considering perceptual interactions and concepts from signal detection theory, these models could predict the CS dependence on the sound level of the T. In these alternative implementations, the animals response probabilities were used as a guide in making assumptions about the "effective stimuli".     

思想考古方法与中国哲学史研究

中国哲学史研究中长期运用的主要方法是经典的解读及理论的分析,但这种方法并不是惟一的、完全没有问题或缺陷的,所以,必须引入一些新的方法如思想考古的方法予以补充。所谓思想考古,即是借鉴历史学和人类文化学等学科的田野调查方法,去思想家生活、求学、家居、从业的地方进行详细的实地考察,以感受和体验研究对象的情感、思绪,把思想家的思想还原为在具体情境中的思想,找到其思想学说或行为的外在根据,并进而印证或质疑某些史书中对思想家的言行记载,对某些语焉不详的史料或有争议的问题做出分析与考辨。     

A regular arrangement of SmH2 fibres in an alpha-Fe matrix,found after the hydrogenation-disproportionation processing of Sm2Fe17

In the course of a study on microstructural changes in Sm2Fe17 during a hydrogenation-disproportionation-desorption-recombination process, a peculiar microstructure has been observed just after the hydrogenation-disproportionation processing. SmH2 crystals, formed as a result of decomposition of the Sm2Fe17 compound, are present with a fibrous shape, about 7 nm in diameter and 1 mum in length. These SmH2 fibres, all with the same orientation, are arranged at nearly regular intervals of about 11nm and with a definite orientation relationship to the alpha-Fe matrix, <110> Fe// <110> SmH2.     

Valence band structure of the NiAl–Mo alloy from the photoelectron spectrum

The valence band structures of the NiAl–Mo alloy was investigated by photoelectron spectroscopy. The valence band spectra of the NiAl–Mo alloy was shifted away from the Fermi level so that the Ni-d-band centroid moved to a higher energy by 0.22 eV as Mo was added. A possible explanation lied in the overlap of Ni-d bands in the energy with Mo-d and Al-p bands. The participation of Mo-d bands was correlated with the site preference of Mo in NiAl alloys.     

Aggression in Toddlers: Associations With Parenting and Marital Relations

This study examined the relation among parenting factors, marital relations, and toddler aggression. A structured questionnaire was administered to both parents of 254 2-year-olds. The authors used correlation and hierarchical multiple regression analyses to assess the extent to which certain personality traits, drug use, parenting style, and marital conflicts were related to the toddlers' aggressive behavior. Results showed that the maternal child-rearing and parental aggression domains had a direct effect on toddler aggression. The domain of maternal child rearing also served as a mediator for the domains of marital relations, paternal child rearing, parental aggression, and parental drug use. The findings indicated that maternal child-rearing practices, personality attributes, and drug use were more important than paternal attributes in relation to toddler aggression. Implications for prevention among families at risk are discussed.     

Dispositional and Situational Autonomy as Moderators of Mood and Creativity

Although previous research suggests that mood can influence creativity, the controversy about the effects of positive and negative moods has raged for years. This study investigated how the relationship between induced mood and creativity is moderated by dispositional and situational autonomy. It contrasted the different moderating effects of the 2 kinds of autonomy. In Experiment 1, 93 participants completed a questionnaire about dispositional autonomy and performed a creative task after watching 1 of 3 film clips, which were to induce positive, negative, or neutral moods. The results of experiment 1 indicated that positive moods prompted creativity and negative moods inhibited creativity when individuals were low in dispositional autonomy (low in autonomous orientation or high in impersonal orientation). In Experiment 2, 73 participants engaged in a game to manipulate levels of situational autonomy and induce positive or negative moods. The results of experiment 2 showed that positive moods fostered greater creativity than did negative moods when individuals were in full-autonomy condition. The different moderating effects of dispositional and situational autonomy are discussed.     

Hedonic Evaluation over Short and Long Retention Intervals: The Mechanism of the Peak–End Rule

The peak–end rule is used to explain how people make retrospective hedonic evaluations. This study advances our understanding of its mechanism by identifying the different effects of the rule on such evaluations over short and long retention intervals. The results of two experiments show that (i) respondents constructed their retrospective hedonic evaluations on the basis of the peak and end affects only over a short retention interval, not over a long one; and (ii) respondents relied on episodic information to construct their evaluations over a short retention interval, whereas they relied on both semantic and episodic information to construct their evaluations over a long retention interval. Our study also suggests that the “watershed” between short and long retention intervals is likely to lie between 3 and 7 weeks. Copyright © 2012 John Wiley & Sons, Ltd.     

Big-five personality and BIS/BAS traits as predictors of career exploration: The mediation role of career adaptability

Based on career construction theory, the current research examined whether career adaptability mediates the relations of the personality traits (Five-Factor Model personality traits and behavioral inhibition and activation systems (BIS/BAS)) to career exploration behavior. Results from a survey in Chinese university students (N = 264) showed that career exploration correlated negatively with neuroticism, and positively with openness to experience, extroversion, agreeableness, conscientiousness and BAS. Results of regression analyses further showed that openness to experience, agreeableness, conscientiousness and BAS served as the strongest predictors for career exploration. In addition, career adaptability was shown to be a key mediator for the relationships between personality traits and career exploration behavior. Career concern and career curiosity were the more important dimensions in the mediation model. These findings advance current understandings on how different personality traits predict career exploration behavior.
