Sino-foreign cooperative education plays an important role in undergraduate education. It has also proved itself popular in higher vocational education in recent years, in which foreign teachers are undertaking the task of teaching some specialized courses. The teaching by foreign teachers has certain irreplaceable advantages, but nonnegligible disadvantages as well. Questionnaires have been distributed to the students majoring in Landscape Engineering from Shanghai Urban Construction College to investigate the teaching of specialized courses by foreign teachers. Based on the statistics, the advantages and disadvantages of their teaching have been analyzed, and several suggestions on how to adopt the good points and avoid the shortcomings are offered, so as to improve the quality of Sino-foreign cooperative education in higher vocational college.

AbstractThis paper explores how we can apply various modern data mining techniques to better understand Australian Income Protection Insurance (IPI). We provide a fast and objective method of scoring claims into different portfolios using available rating factors. Results from fitting several prediction models are compared based on not only the conventional loss prediction error function, but also a modified loss function. We demonstrate that the prediction power of all the data mining methods under consideration is clearly evident using a misclassification plot. We also point out that this predictability can be masked by looking at just the conventional prediction error function. We then suggest using the stepwise regression technique to reduce the number of variables used in the data mining methods. Apart from this variable selection method, we also look at principal components analysis to increase understanding of the rating factors that drive claim durations of insured lives. We also discuss and compare how different variable combining techniques can be used to weight available predicting variables. One interesting outcome we discover is that principal components analysis and the weighted combination prediction model together provide very consistent results on identifying the most significant variables for explaining claim durations.

The purpose of this study was to test the reliability, validity, and effectiveness of a health-related quality of life (HRQOL) instrument—the MiniAQLQ—among persons with asthma who were using a web-based intervention for guided self-management (www.MyAsthma.com). The MiniAQLQ was completed online in 1999 by 307 participants referred to www.MyAsthma.com by their primary care physicians. Construct validity of the MiniAQLQ was assessed by principal components analysis; reliability was estimated using Cronbach’s alpha coefficient; and differences in means between pretest and posttest were analyzed using paired t test. The analysis produced four empirically meaningful factors with reliability of scores ranging from 0.65 to 0.94. Participants reported significant improvement in HRQOL after participating in this intervention. The four factors (activities, symptoms, emotions, and environment) generated by the principal components analysis empirically supported the four domains used in the development of the MiniAQLQ. Scores for the four factors were internally consistent and assessed the distinct domains. The MiniAQLQ appears to be a psychometrically sound instrument for measuring HRQOL online among asthma patients who are participating in online interventions.

Twenty participants scaled similarities in odour quality, odour intensity and pleasantness/unpleasantness of 10 binary and 5 higher-order mixtures of 5 odorous degradation products from the polymer Polyamide 6.6. The perceived odour qualities of all binary mixtures were represented well as intermediary vectors relative to their component-odour vectors in a three-component principal components analysis. The odour qualities of the “floral/fruity” 2-pentylcyclopentan-1-one and the “sharp/cheese-like” pentanoic acid contributed profoundly to their binary mixtures, as did the “minty” cyclopentanone, but in fewer cases. Conversely, the “ether-like” 2-methyl pyridine and “nutty” butanamide did not contribute much. Odour similarity was shown to be caused by odour quality, rather than odour intensity. Three out of five degradation products formed distinct clusters of odours and were therefore interpreted to be profound contributors to the odour quality of the binary mixtures. The higher-order mixtures created new odour qualities which were completely different and untraceable to their various parts as perceived alone. These results demonstrate that it is critical to research the perception of natural mixtures in order to be able to understand the human olfactory code.

The enterprise practice of teachers in higher vocational colleges is adapt to the needs of the development of higher vocational education. It is an important approach to build “the double teacher” construction. Through researching the data obtained from some higher vocational college teachers' enterprise practice, the paper has done some analysis on the current overall status of the teachers in enterprise practice. We have carried on some explorations about the existing problems in three ways, such as the colleges, teachers and enterprise.

Innovative ability is the important content of higher vocational education. The cultivation of practice and innovation ability of college students is not only confined to a single practice ability, but includes the comprehensive ability cultivating, such as expression, questioning, thinking and so on. Practice has proved that the students comprehensive occupation quality can be improved through the cultivation of students innovation ability. But how to cultivate and improve students innovative ability in business website development teaching is a serious problem for computer teachers. Starting from the reality of business website development teaching in higher vocational college, the paper discusses how to efficiently cultivate the current higher vocational students innovative ability and spirits in classroom teaching mode from several aspects, provides new attempts for future development of higher vocational education.

Fourteen mother–child dyads were videotaped four times over 16 days as they repeatedly read an initially unfamiliar storybook. Videotapes were transcribed and a variety of discourse measures were coded for both mother and child. Principal components analysis was used to combine three maternal and three child variables into a single composite variable, engagement, which described levels and quality of maternal and child participation in extratextual interactions during the first reading session. Dyads with the highest levels of engagement during the first session showed the greatest rates of change for a number of discourse measures. Results are discussed in terms of maternal scaffolding approaches, child participation, the importance of context and the nature of the task, and implications for intervention.
