Students' achievement motivation in Finnish and Chinese higher education and its relation to perceived teaching-learning environments.

This cross-cultural study of Finnish and Chinese students set out to compare the levels of achievement motivation (AM) in order to investigate whether the differences in them might be explained by the different cultural response styles and whether these response styles could be controlled for with a method which includes response style variables as covariates in ANCOVA. This study also scrutinizes relationships between perceived teaching-learning environments (TLE) and AM within each cultural group. The survey sample consisted of 3,035 Finnish and 2,309 mainland Chinese university students. Finnish students were found to rate the level of AM markedly higher than do Chinese students. It was determined that the method applied for response style controlling is not suitable for cross-cultural studies, even though it is recommended for this use. A modification of the method, which is based on robust statistical tools, was found not to change this conclusion, but it can nevertheless be used to obtain useful information about the effects of response style differences. The results also show that similar relationships between AM and TLE could be identified in the data of both groups. However, for the Finnish group AM is related to perceived suitable workload, whereas for the Chinese group it is related to teacher encouragement.

Burnout among Finnish and Chinese university students.

In this study the levels of experienced burnout of Finnish and Chinese university students are compared using School Burnout Inventory (SBI). This study is motivated by earlier studies, which suggest that the level of student burnout is different in the culturally distinct Finnish and Chinese university systems, but which are based on different research instruments for the two groups. The sample studied consisted of 3,035 Finnish students and 2,309 Chinese students. Because of the cross-cultural nature of this study the level of structural equivalence of SBI between the cultural groups was examined and the effect of different response styles on the results was taken into account. Both standard and robust statistical methods were used for the analyses. The results showed that SBI with two extracted components is suitable for cross-cultural analysis between Finnish and Chinese university students. Virtually no difference was found in experienced overall burnout between the Finnish and Chinese students, which means that both university systems contain factors causing similar levels of student burnout. This study also verified that controlling for the response styles is important in cross-cultural studies as it was found to have a distinct effect on the results obtained from mean-level comparisons.

Dental functional traits of mammals resolve productivity in terrestrial ecosystems past and present.

We have recently shown that rainfall, one of the main climatic determinants of terrestrial net primary productivity (NPP), can be robustly estimated from mean molar tooth crown height (hypsodonty) of mammalian herbivores. Here, we show that another functional trait of herbivore molar surfaces, longitudinal loph count, can be similarly used to extract reasonable estimates of rainfall but also of temperature, the other main climatic determinant of terrestrial NPP. Together, molar height and the number of longitudinal lophs explain 73 per cent of the global variation in terrestrial NPP today and resolve the main terrestrial biomes in bivariate space. We explain the functional interpretation of the relationships between dental function and climate variables in terms of long- and short-term demands. We also show how the spatially and temporally dense fossil record of terrestrial mammals can be used to investigate the relationship between biodiversity and productivity under changing climates in geological time. The placement of the fossil chronofaunas in biome space suggests that they most probably represent multiple palaeobiomes, at least some of which do not correspond directly to any biomes of today's world.
