Association of serum leptin and ghrelin with depressive symptoms in a Japanese working population: a cross-sectional study

Leptin and ghrelin have been implicated in the pathogenesis of major depression. However, evidence is lacking among apparently healthy people. This study examined the relationship of these appetite hormones to depressive symptoms in a Japanese working population.

Critical factors in the adaptation and implementation of Japanese Lesson Study in the Australian context

Worldwide interest in Japanese Lesson Study as a vehicle to improve mathematics teaching practice through professional learning has left largely unanswered questions about the extent to which it can be replicated elsewhere. This paper reports on a small-scale research project, Implementing structured problem solving mathematics through lesson study, carried out in three Australian schools during 2012, and continued in a modified form during 2013 and 2014. Two major aims of the project were to investigate critical factors in the adaptation and effective implementation of (1) structured problem-solving mathematics lessons, and (2) Japanese Lesson Study as a model for teacher professional learning in the Australian context. This paper discusses the specific affordances that contributed to both the implementation of structured problem solving and to teachers' professional learning as a result of their participation in this project, as well as the constraints encountered, and the implications of these for the sustainability of lesson study in the Australian context. Critical factors identified by the teachers as contributing to the success of the project included the opportunities for in-depth lesson planning, the presence of large numbers of observers at the research lessons and the post-lesson discussions, and the insight provided by the " knowledgeable other". Major constraints included the difficulty in finding suitable problem solving tasks to match the Australian curriculum, and the teaching culture that emphasises small-group rather than whole-class teaching

Japanese lesson study : a numeracy coach's view

This paper reports findings based on interview data from a professional teacher educator who was a Numeracy Coach for a group of schools that participated in a research project, Implementing structured problem-solving mathematics lessons through Lesson Study. The Numeracy Coach was a highly-skilled professional teacher educator, whose position was such that she was both a support person to the teachers and a participant in the project. Her insights into the processes and effects of Japanese Lesson Study, on teachers, as well as herself, are extremely enlightening, and form the data for this paper. While the evidence is from a single source, the evidence is consistent with other projects into the effectiveness of the Japanese model of Lesson Study. Aspects of the project with implications for teacher professional development are detailed.
