Recent research has demonstrated that preschool children can decode emotional meaning in expressive body movement; however, to date, no research has considered preschool children's ability to encode emotional meaning in this media. The current study investigated 4- (N = 23) and 5- (N = 24) year-old children's ability to encode the emotional meaning of an accompanying music segment by moving a teddy bear using previously modeled expressive movements to indicate one of four target emotions (happiness, sadness, anger, or fear). Adult judges visually categorized the silent videotaped expressive movement performances by children of both ages with greater than chance level accuracy. In addition, accuracy in categorizing the emotion being expressed varied as a function of age of child and emotion. A subsequent cue analysis revealed that children as young as 4 years old were systematically varying their expressive movements with respect to force, rotation, shifts in movement pattern, tempo, and upward movement in the process of emotional communication. The theoretical significance of such encoding ability is discussed with respect to children's nonverbal skills and the communication of emotion. 相似文献

感官动词"摸"所构成的动补结构"摸起来"、"摸上去",二者在语义、句法、语用、单位性质等方面存在着异同。两者在语法单位性质上根据二者语义的不同可视为短语或正向词过渡的短语。 相似文献

Music Education, as well as cultural and musical identities are all being renegotiated, post‐Apartheid, within the so‐called ‘newer’ rather than the commonly known ‘new’ South Africa. The developing situation with certain minority groups is particularly interesting. Education in general has undergone much change since the first democratic elections in 1994: music education specifically has been affected by such change in terms of content, delivery and assessment. Within the South African context, cultural and musical identities are often intertwined with language, racial and even tribal identities, and discussing one implies the others. We are particularly interested here in the role of formal Music Education in relation to white Afrikaners and Indians as they renegotiate their cultural development, including musical aspects. 相似文献

Starting from an applied Bone Marrow Transplantation(BMT) study, the problem of “unexpected protectivity” in competing risks
models is introduced, which occurs when one covariate shows a protective impact not expected from a medical perspective. Current
explanations found in the statistical literature suggest that unexpected protectivity might be due to the lack of independence
between the competing failures. Actually, in the presence of dependence, the Kaplan-Meier curves are not interpretable. Conversely,
the cumulative incidence curves remain interpretable, and therefore seem to be a candidate for solving the problem. We discuss
the particular nature of dependence in a competing risks framework and illustrate how this dependence may be created via a
common frailty factor. A Monte Carlo experiment is set up which accounts also for the association between the observable covariates
and the frailty factor. The aim of the experiment is to understand whether and how the bias showed by the estimates could
be related to the omitted frailty variable. The results show that dependence alone does not cause false protectivity, and
that the cumulative incidence curves suffer the same bias as the survival curves and therefore do not seem to be a solution
to false protectivity. Conversely, false protectivity may occur according to the magnitude and the sign of the dependence
between the frailty factor and the covariate. The paper ends with some suggestions for empirical research.

This study used path analysis to examine the relationship between perceived barriers, acculturation, and role model influence on the career self‐efficacy and career considerations of a sample of Hispanic women. Two path models were examined. The male‐dominated model accounted for 15% of the variance, and the female‐dominated model accounted for 26% of the variance. No relationship was found between the variables of interest and male‐dominated career self‐efficacy and consideration. However, perceived barriers were related to female‐dominated career consideration and Anglo acculturation significantly contributed to female‐dominated career self‐efficacy. Results are discussed with regard to career practice and research with Hispanic women. 相似文献

Nafion溶液在燃料电池、电极修饰、电化学分析、电化学催化等领域具有广泛用途。采用特种高沸点溶剂,获得了溶铸性能优良Nafion的溶液。比较溶铸Nafion膜与原始Nafion膜的IR光谱可以看出,Nafion溶液制备方法未对Nafion膜的化学组成与分子结构产生影响,但溶铸膜的分子排列更加规整有序。将该溶液在PEMFC中应用,其性能优于目前的商品水-醇体系Nafion溶液。 相似文献
