The present study explores the effect of perceived teacher support on three forms of thinking related to creativity. Tests of convergent thinking (by means of the Remote Associates Test), insight thinking (explored through a brain‐teaser test), and divergent thinking (by means of a verbal creativity test) were given to 512 middle school students in China, along with assessments of their perceived teacher support and creative self‐efficacy. The results of this study indicate that perceived teacher support positively predicts convergent thinking and insight thinking, with creative self‐efficacy playing a partial mediating role between perceived teacher support and convergent thinking. However, no significant relationships were found between perceived teacher support and divergent thinking. The findings partly lend support to the expectancy–value model of achievement motivation that teacher’s behavior influences student performance through self‐belief pathway. 相似文献

The polychoric instrumental variable (PIV) approach is a recently proposed method to fit a confirmatory factor analysis model with ordinal data. In this paper, we first examine the small-sample properties of the specification tests for testing the validity of instrumental variables (IVs). Second, we investigate the effects of using different numbers of IVs. Our results show that specification tests derived for continuous data are extremely oversized at all sample sizes when applied to ordinal variables. Possible modifications for ordinal data are proposed in the present study. Simulation results show that the modified specification tests with all available IVs are able to detect model misspecification. In terms of estimation accuracy, the PIV approach where the IVs outnumber the endogenous variables by one produces a lower bias but a higher variation than the PIV approach with more IVs for correctly specified factor loadings at small samples. 相似文献

Using data from the Longitudinal Study of Chinese Children and Adolescents (LSCCA), this study is the first to examine the roles of the dopamine D2 receptor (DRD2) gene polymorphisms (i.e., TaqIA and A241G) and maternal positive parenting at ages 10 and 11 years in the trajectories of depressive symptoms from early to mid-adolescence (ages 11 to 16 years). In a sample of 1090 Chinese adolescents (50% girls), three trajectories of depressive symptoms were identified: (i) low-stable (36.1%), (ii) moderate-increasing (44.5%), and (iii) high-increasing (19.4%). A241G AA homozygotes and youth exposed to lower levels of maternal positive parenting were both at increased odds to follow the high-increasing vs. low-stable trajectory. Moreover, the A241G polymorphism interacted with maternal positive parenting to distinguish the moderate-increasing trajectory from the high-increasing and the low-stable trajectories. For A241G G-allele carriers, but not AA homozygotes, exposure to high quality of maternal parenting decreased the odds to follow the high-increasing vs. moderate-increasing trajectory of depressive symptoms. For AA homozygotes, but not G-allele carriers, high quality of maternal parenting increased the odds to follow the low-stable vs. moderate-increasing trajectory. The DRD2 TaqIA polymorphism had neither a direct nor an interactive effect with maternal positive parenting on trajectory membership. The current findings highlight the importance of investigating gene-by-environment interactions (G × E) in trajectories of depressive symptoms over adolescence, and support a developmental versus static nature of G × E effects. 相似文献

The wetting behaviour and associated pressure effect of water in single-walled carbon nanotubes (SWCNTs) are investigated through molecular dynamics (MD) simulations. It is found that water molecules can enter SWCNTs via surface diffusion, and the effective infiltration rate increases with pressure. The effect of pressure on infiltration rate is highly non-linear, exhibiting characteristics of both hydrophilic and hydrophobic surfaces. There exists a nominal infiltration pressure that is dependent on the SWCNT size, above which the water flux is significantly increased. 相似文献

ABSTRACTWe have theoretically investigated the control of wave-vector filtering (WVF) by introducing δ-doping into a magnetically modulated nanostructure fabricated by depositing ferromagnetic stripes on top and bottom of a GaAs/AlxGa1 ?xAs heterostructure. With the help of an improved transfer matrix method, the Schrödinger equation for electrons in this semiconductor nanostructure is solved exactly and the transmission efficient calculated numerically. We demonstrate that the WVF efficiency is associated closely with the weight and position of the δ-doping, which may be helpful for designing a controllable electron-momentum filter based on such a magnetically modulated semiconductor nanostructure. 相似文献

The Wentzel–Kramers–Brillouin method is employed to study the cut-off frequencies of the horizontal shear waves in a freestanding functionally graded piezoelectric–piezomagnetic material film with the electrically and magnetically open boundary conditions. An analytical solution, which could be used in analyzing the problems of various functionally graded materials, is proven to have high precision by analytical analysis and a numerical example. The results reveal that the set of cut-off frequencies is a series of approximate arithmetic progressions. A theoretical foundation based on the relationship between the cut-off frequencies and the materials’ gradient property is established for nondestructive evaluation. 相似文献

It is reported that the application of a high magnetic field is capable of inducing the formation of twinned dendrites during directional solidification of Al–4.5wt%Cu alloy. Numerical results reveal that a unidirectional thermoelectric magnetic force acts on tilted dendrites during directional solidification under a magnetic field. This force should be responsible for the formation of twinned dendrites. The work may initiate a new method for inducing twinned dendrites in Al-based alloys via an applied high magnetic field during directional solidification. 相似文献

This article describes the development and validation of a scale that measures two distinct needs for individuals to manage their social "face". Scale development process resulted in an 11-item Consciousness of Social Face (CSF) scale made up of the following two correlated dimensions: desire to gain face and fear of losing face. The two-factor correlated structure of CSF scale was stable across multiple samples of both students and non-students subjects. The construct validity of CSF scale, including convergent validity, discriminant validity, and criterion-related validity was also demonstrated by examining relationships with other personality or demographical variables. 相似文献
