Four-phonon model of soft-matter quasicrystals is proposed, in which there are three solid phonons and one fluid phonon. With this model, the vibration spectrum of soft-matter quasicrystals can be obtained. The generalized Debye frequency, generalized Debye temperature and the thermodynamic functions of soft-matter quasicrystals are observed. The results on the specific heat of soft-matter quasicrystals demonstrate the contributions of both solid phonons and fluid phonon, respectively. 相似文献

鼻咽癌是我国高发恶性肿瘤之一,发病率为头颈部恶性肿瘤之首。鼻咽癌对放疗、化疗均敏感。单纯的放射治疗虽然能够使早期患者获得很好的局部控制率,但是对于局部晚期患者而言,其5年生存率难以令人满意,治疗失败主要是因为区域复发和远处转移。化学治疗对放疗起到了补充作用,临床应用目前主要有同期化疗、辅助化疗、诱导化疗三种。本文对过去20年间化疗在局部晚期鼻咽癌治疗中的应用归纳总结。 相似文献

The present study is a cross-sectional survey that investigates ethical practices among Chinese psychotherapists from the perspective of a large representative sample of Chinese clients (N?=?1,100). In reports from clients, we found that psychotherapists did poorly in providing informed consent and had other ethical difficulties in the therapeutic setting and with dual relationships. We conclude that Chinese culture, especially Confucianism, had significant impact on the attitudes toward the psychotherapists' ethical practices, which complicated ethical dilemmas. It is important for cross-cultural psychotherapists to become sensitive to the influences of traditional Chinese culture when counseling Chinese clients. 相似文献

Anchoring in judgments is the tendency for the final judgment to be biased toward the initial estimate through insufficient adjustment. In the context of the detection of deception, it has been used to explain phenomena such as negative absolute leakage and the truthfulness bias. We examined the influence of order of judgment type on attitude ratings, accuracy, and the truthfulness bias. Receivers of communications should tend to anchor their judgments on the sender's attitudinal position if asked to make attitude judgments first and on the sender's behavior if asked to make truthfulness judgments first. The results partly support these predictions. Negative absolute leakage, accuracy, and the truthfulness bias were not significantly different for those who made attitude judgments before truthfulness judgments. However, results show that accuracy decreased as the session continued and there was no difference in the confidence with which truth and deception judgments were made, but there was a positive relation between confidence and truthfulness bias. 相似文献

Auditory distractions can have serious consequences in critical situations such as driving. Mobile phones, radios, media players, and information devices that interpret and produce speech are increasingly common in vehicles, but the threats to visual attention are not yet fully understood. In three experiments, we found that most speech tasks had relatively small adverse effects on the detection of a briefly presented target among distractors across a 60° subarea of the visual field. Although there was a little impact on detectability, moderately difficult speech tasks slowed responding relative to silence. Our most demanding condition—generating and speaking a word beginning with the last letter of another word—had the greatest effects on accuracy and latency, with responding slowed by about 900 ms. An impairment of this magnitude presents a significant threat to safe driving and calls into question the belief that hands‐free voice‐controlled devices are the answer to the problem of driver distraction.

This study extended the concept of collective efficacy to supplement the variable of career self-efficacy to predict vocational exploration and commitment among adolescents. We developed a Collective Contributions to Career Efficacy Scale (CCCE) to measure adolescents' perceived contributions from parents, teachers, and peers on their career-related matters. A total of 1175 high school students from Hong Kong, Shanghai and Michigan participated in the study by completing the CCCE, the Career Decision Self-Efficacy Scale (CDSE-SF), and the Vocational Exploration and Commitment Subscale (VEC). Using multi-sample Structural Equation Modeling, we found that the effect of CCCE on VEC was mediated by CDSE. Although we found cultural differences in the overall level of the vocational measures among the Hong Kong, Shanghai, and American students, the mediation model was confirmed in all three groups of students. 相似文献

The aim of the present study was to investigate the time course of the positive advantage in the expression classification of faces by recording event-related potentials (ERPs). Although neutral faces were classified more quickly than either happy or sad faces, a significant positive classification advantage (PCA)—that is, faster classification for happy than for sad faces—was found. For ERP data, as compared with sad faces, happy faces elicited a smaller N170 and a larger posterior N2 component. The P3 was modulated by facial expressions with higher amplitudes and shorter latencies for both happy and neutral stimuli than for sad stimuli, and the reaction times were significantly correlated with the amplitude and latency of the P3. Overall, these data showed robust PCA in expression classification, starting when the stimulus has been recognized as a face revealed by the N170 component. 相似文献

Eye-tracking technique and visual search task were employed to examine the cognitive advantage for one’s own name and the possible effect of familiarity on this advantage. The results showed that fewer saccades and an earlier start time of first fixations on the target were associated with trials in which participants were asked to search for their own name, as compared to search for personally familiar or famous names. In addition, the results also demonstrated faster response times and higher accuracy in the former kind of trials. Taken together, these findings provide important evidence that one’s own name has the potential to capture attention and that familiarity cannot account for this advantage. 相似文献

We examined the effects of cue luminance on visual orienting. Experiment 1 established that the commonly-found early facilitation and late inhibition of return (IOR) effects were independent of cue luminance with single cues in terms of their amplitude, although IOR was delayed in the low compared to the high luminance cue condition. In contrast, Experiment 2 revealed that, with dual cues of mixed luminance, both facilitation and IOR effects were found only with bright cues. When cues had equal luminance, however, there were cueing effects for two cued locations but only when the cues were bright. The data were accommodated in a neural network model of biased competition in which cueing effects emerge at more than one location provided input activation is sufficient to overcome competitive damping of the selection system. 相似文献
