This study explored the relationship between acculturation level and vocational identity among 112 graduate and undergraduate Taiwanese international students attending two midwestern universities. The results revealed that Taiwanese international students who were older and who had a shorter length of U.S. residency were more likely to identify themselves as Asian. The results also indicated that Taiwanese international students who were older and who had a lower acculturation level had higher vocational identity. 相似文献

Neural Oscillation Reveals Deficits in Visuospatial Working Memory in Children With Developmental Coordination Disorder 下载免费PDF全文
The electroencephalographic (EEG) oscillations associated with visuospatial working memory (VSWM) were examined in children with developmental coordination disorder (DCD; 10–11 years; N = 29) and typically developing (TD) children (10–11 years; N = 29). Behaviorally, DCD showed poorer VSWM than TD, which coincided with the diminished ability of DCD in modulating neural oscillations. Furthermore, prestimulus oscillatory alpha activity was correlated with VSWM performance. The results suggest that children with DCD might have a reduced ability to encode and recognize new information, and in particular have difficulty in maintaining task‐relevant information, resulting in poorer VSWM. This study thus concludes that changes in oscillatory EEG activity reflect some of the problems leading to cognitive deficits in DCD. 相似文献

The operational properties of the integration and product of Chebyshev polynomials are used in the analysis of bilinear systems by the approximation of time functions by truncated Chebyshev series. The operational properties are also applied to determine the unknown parameters of a general bilinear system from the input-output data. Examples with excellent results are given. 相似文献

In this study, we used multi-level regression modelling to assess the influence of age, sex, body size, skinfold thicknesses, maturity, thigh muscle volume and isokinetic leg strength on the development of load- and inertia-adjusted peak (1 s) and mean power (30 s) determined using the Wingate anaerobic test. Fifteen males and 19 females were measured twice, first aged 10.0 +/- 0.3 years and then aged 11.8 +/- 0.3 years. Initial models identified body mass and height as significant explanatory variables (P < 0.05) for peak power and mean power, with an additional age effect for the former. No significant differences between the sexes or maturity effects were observed for either peak or mean power (P > 0.05). The introduction of sum of skinfolds improved the fit of the model and rendered the height term non-significant for both peak and mean power (P> 0.05). An age effect became apparent for mean power. When isokinetic leg strength and thigh muscle volume were entered into the model, the latter exerted a significant effect on both peak and mean power (P< 0.05), whereas isokinetic leg strength was not a significant explanatory variable for either (P> 0.05). In conclusion, thigh muscle volume exerts a positive influence on young people's short-term power output, which is additional to the effects of body mass, sum of skinfolds and age. 相似文献

This article quantitatively summarizes experimental and quasi‐experimental studies on teaching students with mathematics difficulties (MD) published between 2000 and 2014, research that was available following earlier syntheses. It reports the analysis of effect sizes of 25 intervention studies on participant characteristics, intervention parameters, domains of mathematics interventions, and instructional approaches and components. Results indicate that several participant characteristics (e.g., grade level and level of mathematics difficulties) and intervention parameters (e.g., methodological soundness, intervention agent, and grouping) mediated the treatment effects. In addition, different types of instructional approaches and several instructional components contributed to the improvements in mathematics performance in students with MD. 相似文献

Effects of Tier 2 and Tier 3 Mathematics Interventions for Second Graders with Mathematics Difficulties 下载免费PDF全文
Minyi Shih Dennis 《Learning disabilities research & practice》2015,30(1):29-42
Two studies were conducted to examine the effects of Tier 2 and Tier 3 mathematics interventions on students with mathematics learning difficulties. In the first study, the work of Bryant et al. was replicated and expanded upon by documenting the sustained effects of a Tier 2 mathematics intervention on mathematics performance by second graders. In the second study, the Tier 2 intervention was intensified to a Tier 3 intervention through increases in two instructional features: group size and dosage. The results of the first study showed that the Tier 2 intervention improved mathematics performance for the majority of student participated in the study, and the effect of the intervention was sustained for the majority of students who responded to the Tier 2 intervention. The results of the second study showed that intensified Tier 3 intervention that involved one‐on‐one instruction and extended time for daily lessons may benefit students who have persistent difficulties with learning mathematics. 相似文献

Cognitive diagnosis models provide profile information about a set of latent binary attributes, whereas item response models yield a summary report on a latent continuous trait. To utilize the advantages of both models, higher order cognitive diagnosis models were developed in which information about both latent binary attributes and latent continuous traits is available. To facilitate the utility of cognitive diagnosis models, corresponding computerized adaptive testing (CAT) algorithms were developed. Most of them adopt the fixed‐length rule to terminate CAT and are limited to ordinary cognitive diagnosis models. In this study, the higher order deterministic‐input, noisy‐and‐gate (DINA) model was used as an example, and three criteria based on the minimum‐precision termination rule were implemented: one for the latent class, one for the latent trait, and the other for both. The simulation results demonstrated that all of the termination criteria were successful when items were selected according to the Kullback‐Leibler information and the posterior‐weighted Kullback‐Leibler information, and the minimum‐precision rule outperformed the fixed‐length rule with a similar test length in recovering the latent attributes and the latent trait. 相似文献

Chelladurai developed the Multidimensional Model of Leadership, which was designed to be situation-specific to examine leadership behaviour and effectiveness in sporting contexts. Applying Chelladurai's concept to the Singapore sporting context, this study aimed to assess the impact of congruence between perceived and preferred leadership behaviours on satisfaction with leadership among college student-athletes in Singapore. Data were collected from 185 college student-athletes enrolled in the five local tertiary institutes. The questionnaire utilized in this study consisted of the perception and preference versions of the Revised Leadership Scale for Sports and seven items measuring satisfaction with coaching leadership. Confirmatory factor analysis and a series of hierarchical multiple regression procedures were carried out to test the psychometric properties of the leadership scale and the hypothesized relationship between congruence levels and satisfaction. Results revealed congruence of perceived and preferred behaviour in social support was a significant indicator of athletes' satisfaction. Possible implications from the findings were discussed in an effort to better understand coaching effectiveness in Singapore. 相似文献
