Expressive Vocabulary Predicts Nonverbal Executive Function: A 2-year Longitudinal Study of Deaf and Hearing Children     

Anna Jones  Joanna Atkinson  Chloe Marshall  Nicola Botting  Michelle C. St Clair  Gary Morgan 《Child development》2020,91(2):e400-e414

Numerous studies suggest an association between language and executive function (EF), but evidence of a developmental relationship remains inconclusive. Data were collected from 75 deaf/hard-of-hearing (DHH) children and 82 hearing age-matched controls. Children were 6–11 years old at first time of testing and completed a battery of nonverbal EF tasks and a test of expressive vocabulary. These tasks were completed again 2 years later. Both groups improved their scores on all tasks over this period. DHH children performed significantly less well than hearing peers on some EF tasks and the vocabulary test at both time points. Cross-lagged panel models showed that vocabulary at Time 1 predicted change in EF scores for both DHH and hearing children but not the reverse.  相似文献   

Efficient implementation of associative classifiers for document classification     

Yongwook Yoon  Gary Geunbae Lee 《Information processing & management》2007

In practical text classification tasks, the ability to interpret the classification result is as important as the ability to classify exactly. Associative classifiers have many favorable characteristics such as rapid training, good classification accuracy, and excellent interpretation. However, associative classifiers also have some obstacles to overcome when they are applied in the area of text classification. The target text collection generally has a very high dimension, thus the training process might take a very long time. We propose a feature selection based on the mutual information between the word and class variables to reduce the space dimension of the associative classifiers. In addition, the training process of the associative classifier produces a huge amount of classification rules, which makes the prediction with a new document ineffective. We resolve this by introducing a new efficient method for storing and pruning classification rules. This method can also be used when predicting a test document. Experimental results using the 20-newsgroups dataset show many benefits of the associative classification in both training and predicting when applied to a real world problem.  相似文献   

The Bivariate Distribution of a Median Smoothed Markov Chain     

Federico Kuhlmann  Gary L. Wise 《Journal of The Franklin Institute》1982,313(2):107-118

Median based smoothing algorithms have received considerable attention in the last few years. Their properties make them sometimes superior to linear smoothers. In this paper we develop an expression for the bivariate distribution of a median- smoothed Markov chain and we illustrate one application of it by comparing the power spectra of the input and the output of a median smoother when the input is binary valued.  相似文献   

Dependency structure language model for topic detection and tracking     

Changki Lee  Gary Geunbae Lee  Myunggil Jang 《Information processing & management》2007

In this paper, we propose a new language model, namely, a dependency structure language model, for topic detection and tracking (TDT) to compensate for weakness of unigram and bigram language models. The dependency structure language model is based on the Chow expansion theory and the dependency parse tree generated by a linguistic parser. So, long-distance dependencies can be naturally captured by the dependency structure language model. We carried out extensive experiments to verify the proposed model on topic tracking and link detection in TDT. In both cases, the dependency structure language models perform better than strong baseline approaches.  相似文献   

The relationship between alumni satisfaction and work experiences   总被引：2，自引：2，他引：2  

Gary R. Pike 《Research in higher education》1994,35(1):105-123

Although alumni surveys frequently include questions about work experiences, little information is available about the relationship between work experiences and alumni satisfaction with college. The results of the present research indicate that work experiences are significantly related to alumni ratings of their college experiences. Specifically, alumni who are satisfied with their jobs are more likely to report being satisfied with their education experiences. The results of this research also indicate that women are less satisfied with their pay than men. Compared to men, women are neither more dissatisfied with the types of work they are performing nor more likely to be looking for another job. Counter to expectation, dissatisfaction with pay has a more significant effect on ratings of college experiences for women than for men. Presented at the 1993 AIR Forum, Chicago, May 1993.  相似文献

Using a hypertext environment for teaching process writing: An evaluation study of three student groups     

Linda Lohr  Steven M. Ross  Gary R. Morrison 《Educational technology research and development : ETR & D》1995,43(2):33-51

The present research consisted of a comprehensive evaluation of a hypertext model for teaching process writing at the junior high and high school level. Interests were to determine how two teachers and three different age groups of students used and reacted to the model, specifically, its embedded design features of model stories, note cards, idea buttons, mini-lessons, branching buttons, and cut-and-paste-tools. Results showed applications of the embedded features to vary based on teacher attitudes, feature attributes (e.g., ease of use and appeal), and student characteristics. Older students made more usage of many of the features, but were less positive about the hypertext model given their greater involvement with completing writing assignments rather than with exploring new forms of writing. The implications of the results are discussed regarding the instructional design and classroom implementation of new technologies for teaching process writing strategies.This study was conducted as a doctoral dissertation completed by the first author at the University of Memphis under the supervision of the second and third authors.  相似文献
