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

This investigation examined the original thinking of preschool children (N=48). The instruments were lenient and stringent solution‐standard measures of original problem solving and two subsets of the Wechsler Preschool and Primary Scale of Intelligence. Scores for popular and original responses were computed for the lenient and stringent measures. Findings supported the construct validity of conceptualizations of original problem solving based on ideational fluency within the lenient measures, but not within stringent measures. Findings also indicated that the lenient measures are better predictors of real‐world original behavior than stringent measures, especially for young children. The need for development of more reliable and valid measures for assessing real‐world creative behavior is discussed. 相似文献

The influence of vehicular control on motion sickness has implications for theories of motion sickness etiology. We asked whether motion sickness susceptibility might also be related to the control of non-vehicular locomotion. Participants were exposed to a console video game that featured ambulatory locomotion of a virtual avatar. In a yoked control design, individuals either played the game (players) or watched another participant's recorded game play (viewers). Viewers were more likely than players to report motion sickness. During exposure to the video game players moved more than viewers, and the movement of players was more predictable or self-similar than the movement of viewers. Coupling of movement within player-viewer pairs was greater for pairs in which the viewer later reported motion sickness than for pairs in which both participants stated that they were not motion sick. The results reveal that motion sickness incidence can be influenced by the control of stimulus motion, in general, and is not limited to control of vehicular motion. We discuss implications of these findings for theories of motion sickness etiology. 相似文献

This cross‐sectional study investigated the significant differences in students’ self‐efficacy and their involvement in learning science. Nine hundred and twenty‐two elementary school fifth graders, 499 junior high school eighth graders, and 1455 senior or vocational high school eleventh graders completed the students’ questionnaire. Analyses of variance (ANOVAs) and independent t‐tests compared the significant similarities and differences across school levels and genders. The initial findings were as follows: A sharp decline in boys’ and girls’ self‐efficacy scores from elementary to secondary school levels; boys have significantly higher self‐efficacy scores than girls at vocational and senior high school levels; students with more involvement in science learning presented significantly higher self‐efficacy scores than those with less involvement. The significant discrepancies in terms of gender and age in students’ self‐efficacy and involvement in learning science need to be addressed. Implications and limitations are provided. 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

The current research examined the moderating role of employees' need for cognitive closure in the relationship between their perceived person–job fit and their work-related attitudes. In Study 1, a survey was conducted among 176 Chinese employees from various organizations, and the results confirmed that both demand–ability fit and need–supply fit were positively related to employees' job satisfaction; moreover, these relations were stronger among people with higher need for closure than those scoring lower in need for closure. In Study 2, a survey was conducted among 242 employees from a Chinese city government, and the results replicated the findings of Study 1, but also found that need for closure moderated the relation between demand–ability fit and turnover intention. These results have important implications for research in organizational psychology and human resource management. 相似文献

Two studies investigated whether one dimension of action–state orientation, namely, persistence-volatility, would moderate the effect of implementation intentions on goal progress. Results from Study 1 indicated that spontaneous implementation intentions predicted goal progress 2 weeks later only among participants who scored high on persistence. In Study 2, participants were randomly allocated to an implementation intentions group and a control group. Results indicated that persistence was positively associated with goal progress among participants in the implementation intentions group but not among those in the control group. Theoretical and practical implications of these findings were discussed. 相似文献

The present study examined the developmental issue of cognitive factors that explain Chinese literacy. Phonological awareness, rapid automatized naming, short-term memory, orthographic awareness and morphological awareness and two literacy tasks (character naming and reading fluency) were administered to 408 second-graders, 428 fourth-graders and 496 six-graders. Results from linear regression analysis and path analysis model showed that the five reading-related cognitive constructs explained unique variances in character naming. Second, character naming is primary for reading fluency after controlling other cognitive constructs; third, the relation between the cognitive factors and literacy changes significantly as a function of reading skills. Results give a clear direction to understanding Chinese reading development. 相似文献
