Who Cares? Attitudes of High School Students From Various Countries Towards Global and Domestic Environmental Issues

This study focused on attitudes of 16 year-old students from six countries towards environmental issues on domestic and global scales. Male and female students from China, Guinea, Japan, Malaysia, Ukraine and Vietnam expressed their level of concern about the following in regard to their country and the world: (a) air quality, (b) drinking water quality, (c) pollution caused by atomic power plants, (d) clearing of forests, (e) extinction of plants and animals, (f) climate change and (g) global disaster. This research focused on gender and cultural variability and invariance under diverse conditions of students’ backgrounds. The most pronounced intercultural regularity found was the prioritization of certain issues. In all countries, both genders showed similar priorities when assessing global and domestic environmental issues. The differences were mainly in the level of anxiety expressed towards environmental problems. While in some countries the level of concern expressed by girls was higher than that of boys, there was no such pattern across all cultures. Only in Japan were the ratings given by boys higher when comparing to those of girls. Another intercultural regularity was that the level of concern about the world’s environmental problems listed above is higher for both genders than about own country with exceptions of specific pressing national problems

Parents’ perceptions on previous and current science education system in Japan

Parents’ views, beliefs, and experiences greatly affect children’s attitudes toward education. The research aimed to identify the parents’ perception in the past, present, and their desired priorities in science education as well as investigated the adolescents’ perceptions based on gender and academic performance on science. As a survey study, this research relied on a questionnaire as the primary method of data collection which the data gained then was analysed by using statistical descriptive (percentage). The results showed that the priorities in education have shifted toward physics and chemistry in recent decades. Moreover, biology and earth science were found to be perceived as ‘easy’ and ‘secondary’ areas in comparison to the ‘superior’ ones (physics and chemistry). This has been strengthened by the critical situation for earth science, as the education system of Japan often does not al low the students to select it. Thus, the parents wished for a more balanced system. There was a difference in adolescents’ perceptions of science areas based on gender and academic performance. Physics and chemistry were associated with boys and top performers, while biology and earth science were supposed to ‘fit’ girls and low performers

How seaweeds release the excess energy from sunlight to surrounding sea water

International audienceWe report an atomistic insight into the mechanism regulating the energy released by a porphyra-334 molecule, the ubiquitous photosensitive component of marine algae, in a liquid water environment upon an electron excitation. To quantify this rapidly occurring process, we resort to the Fourier analysis of the mass-weighted auto-correlation function, providing evidence for a remarkable dynamical change in the number of hydrogen bonds among water molecules and between the porphyra-334 and its surrounding hydrating water. Hydrogen bonds between the porphyra-334 and close by water molecules can act directly and rather easily to promote an efficient transfer of the excess kinetic energies of the porphyra-334 to the surrounding solvating water molecules via an activation of the collective modes identified as hydrogen-bond stretching modes in liquid water which eventually results in a disruption of the hydrogen bond network. Since porphyra-334 is present in seaweeds, aquatic cyanobacteria (blue-green algae) and red algae, our findings allow to address the question how algae in oceans or lakes, upon sunlight absorption, can release large amounts of energy into surrounding water without destabilizing neither their own nor the H 2 O molecular structure
