    Life-Span Developmental Psychology: Midlife and Later Years in Western and Non-Western Societies

    No full text
    This chapter discusses the basis on which studies have been done on the later years of life in Western and non-Western cultures. It suggests that because Westerners value independence, most research on aging in Western societies has focused on how to help the individual maintain his or her functional independence throughout the life-span. Non-Westerners, on the other hand, value interdependence. Therefore, most research on aging has focused on the availability of social support in later life. But with Westernization influences in non-Western societies, there should be a shift in research efforts in order to accommodate a new understanding of aging and human development that includes the promotion of functional independence in later life

    Samia cynthia versus Bombyx mori : Comparative gene mapping between a species with a low-number karyotype and the model species of Lepidoptera

    We performed gene-based comparative FISH mapping between a wild silkmoth, Samia cynthia ssp. with a low number of chromosomes (2n = 25-28) and the model species, Bombyx mori (2n = 56), in order to identify the genomic components that make up the chromosomes in a low-number karyotype. Mapping of 64 fosmid probes containing orthologs of B. mori genes revealed that the homologues of either two or four B. mori chromosomes constitute the S. c. ricini (Vietnam population, 2n = 27♀/28♂, Z0/ZZ) autosomes. Where tested, even the gene order was conserved between S. c. ricini and B. mori. This was also true for the originally autosomal parts of the neo-sex chromosomes in S. c. walkeri (Sapporo population, 2n = 26♀/26♂, neo-Wneo-Z/neo-Zneo-Z) and S. cynthia subsp. indet. (Nagano population, 2n = 25♀/26♂, neo-WZ1Z2/Z1Z1Z2Z2). The results are evidence for an internal stability of lepidopteran chromosomes even when all autosomes had undergone fusion processes to form a low-number karyotype

    What’s missing in model-based teaching?

    No full text
    In this study, the author investigated how four science teachers employed model-based teaching (MBT) over a 1-year period. The purpose of the research was to develop a baseline of the fundamental and specific dimensions of MBT that are present and absent in science teaching. Teacher interviews, classroom observations, and pre and post-student assessments were gathered. Using a Generate-Evaluate-Modify framework as a theoretical guide, the author identified three fundamental aspects of MBT that were not apparent in an analysis of the teaching methods. Drawing on these findings, the author hypothesizes the consequent impact of the absence of these aspects on MBT on students’ experiences and performance in science. Implications for core science teacher professional development activities on MBT are discussed
