How Do Children Acquire Early Grammar and Build Multiword Utterances? A Corpus Study of French Children Aged 2 to 4

In the last 50 years, researchers have debated over the lexical or grammatical nature of children's early multiword utterances. Due to methodological limitations, the issue remains controversial. This corpus study explores the effect of grammatical, lexical, and pragmatic categories on mean length of utterances (MLU). A total of 312 speech samples from high‐low socioeconomic status (SES) French‐speaking children aged 2–4 years were annotated with a part‐of‐speech‐tagger. Multiple regression analyses show that grammatical categories, particularly the most frequent subcategories, were the best predictors of MLU both across age and SES groups. These findings support the view that early language learning is guided by grammatical rather than by lexical words. This corpus research design can be used for future cross‐linguistic and cross‐pathology studies.

Exploratory factor analysis to construct a model of university teaching evaluation indicators / Un análisis factorial exploratorio para la construcción de un modelo de indicadores de evaluación docente universitaria

Abstract

This article is a practical application of the technique of factor analysis. Its uniqueness lies in the nature of the variables we set out to study (determinants of the quality of university teaching), the data collection instrument designed for the study (scale assessment questionnaire) and the basic goal of this study, which is simply to seek the views of a representative sample of university students on the elements that form a system of indicators for assessing teaching skills in order to establish a profile of the role of university professor.     

Prediction of elite schoolboy 2000-m rowing ergometer performance from metabolic,anthropometric and strength variables

In 19 elite schoolboy rowers, the relationships between anthropometric characteristics, metabolic parameters, strength variables and 2000-m rowing ergometer performance time were analysed to test the hypothesis that a combination of these variables would predict performance better than either individual variables or one category of variables. Anthropometric characteristics, maximal oxygen uptake (V O 2m ax ), accumulated oxygen deficit, net efficiency, leg strength and 2000-m rowing ergometer time were measured. Body mass, V O 2max and knee extension correlated with 2000-m performance time (r = -0.41, -0.43 and-0.40, respectively; P 0.05), while net efficiency and accumulated oxygen deficit did not. Multiple-regression analyses indicated that the prediction model using anthropometric variables alone best predicts performance (R = 0.82), followed by the equation comprising body mass, V O 2max and skinfolds (R = 0.80). Although the regression equations increased the predictive power from that obtained using single variables, the hypothesis that a prediction model consisting of variables from different physiological categories would predict performance better than variables from one physiological category was not supported.     

Teachers' perceptions of in-service teacher training to support curriculum change in physical education: The Hong Kong experience

The purpose of this study was to evaluate the effectiveness of an in-service training program and understand teachers' receptivity to curriculum change in physical education. A total of 183 primary school teachers were recruited as participants on a voluntary basis. They were asked to respond to a questionnaire about their receptivity to changes in the current physical education curriculum as well as their views on the effectiveness of a teacher development program that was organized by the Chinese University of Hong Kong. The results showed that the participants felt that in-service training was needed to equip them to implement a physical education program in line with the curriculum reform. The in-service training program was deemed to be practical and effective, bringing about good communication among school teachers, educational experts, and government curriculum officers. In terms of their receptivity to curriculum change, the participants generally had positive attitudes to the innovation and showed further support for the change after attending the program. The role of the principal and the need for school support for the reform are discussed in the concluding section.

基于非线性半参数模型的似大地水准面系统误差研究

全球重力场模型EGM96是全球性大地水准面模型,由该模型确定的重力大地水准面与测区似大地水准面存在一个系统差值。本文引入非线性半参数模型,用非参数分量表示该系统差值,进行数据处理,同时与多项式拟合法进行比较,证明了非线性半参数方法求解结果更好。

InfoFair: an annual computer and information event

Since 1983, the Spencer S. Eccles Health Sciences Library has presented InfoFair, an annual event featuring presentations, exhibits, demonstrations, and workshops on computer and information topics of interest to health professionals and health information providers at the University of Utah Health Sciences Center and throughout Utah. The first InfoFair was held in response to an increasing number of inquiries from library users on how to search MEDLINE from their home or office computers. The focus of InfoFair has expanded and changed over the past nineteen years to reflect changes in library users' computer and information needs, concerns, and interests. While themes and programs have changed, a definite set of trends, guidelines, and procedures have developed based on the experience gained each year. The purpose of this paper is to review and evaluate the changes in InfoFair from 1983 to 2001 and to present information for use by other libraries for planning and presenting similar events.
