In order to investigate the performance of number sense and its relationships with mathematics achievement of Taiwanese students who had just completed the 5th-grade mathematics curriculum, a computerized number sense scale has been developed. This number sense scale includes four factors which are recognizing relative number size, using multiple representations of numbers and operations, judging the reasonableness of estimates of computed results and recognizing the relative effect of operations on numbers. A total of 1,212 students in Taiwan participated in this study. The main findings of this study are summarized as follows. First, the students perform best on “recognizing relative number size” and perform worst on “judging the reasonableness of estimates of computed results”. This finding is consistent with previous studies. It shows that students in Taiwan seem quite poor on judging the reasonableness of estimates of computed results. Second, female students, on average, have higher scores on recognizing the relative number size than male students, even though only a small effect size is found. And, third, the achievements of the students in mathematics are significantly correlated with their number sense, as measured by the average grade for the academic year of 5th-grade students.

This paper examines the scalability of intimacy permissiveness measures in Taiwan by using island-wide survey data. Among models for scaling analysis, the Guttman scaling model and two latent class models – the latent-distance model and Goodman’s scale model – were employed to examine the scalability of the scale measures. The data were drawn from the 2002 Taiwan Social Change Survey (Questionnaire No. 2), conducted by Academia Sinica. A total of 1983 completed interviews were obtained. This study found that the measures of intimacy permissiveness scale (IPS) were able to form a reasonable Guttman-type scale based on three scaling models. In order to understand whether the attitudinal patterns of Taiwanese toward premarital intimacy permissiveness, particularly the existence of sexual double standards, are consistent with those suggested by the previous literature, we conducted multinomial logistic regression of socio-demographic variables on the scale. Gender and age differences were found consistent with previous studies and mostly reconfirmed the appropriateness of the measures of IPS designed for the Taiwan Social Change Survey.

The reliability and validity of four selected scales-namely, job control, psychological demands, supervisor support, and coworker support-from the Chinese Version of the Job Content Questionnaire (C-JCL) were studied in 551 male and 648 female workers in Taiwan. Cronbach's alpha coefficients for job control, supervisor support, and coworker support were all above .80. Whereas it was .55 for psychological demands, indicating insufficient internal consistency for this subscale. Participants responded to questionnaire items relatively consistently over a 3-month period. Exploratory factor analyses disclosed 4 empirical factors, which corresponded closely with theoretical constructs of the JCL. As predicted by the model, lowest levels of job satisfaction were found in workers in "iso-strain" category (i.e., high demands combined with low control and low social support). These findings indicated that the C-JCL is reliable and valid for assessing psychosocial work conditions among Taiwanese workers, although further improvement is needed for the psychological demands subscale.
