Life-Span Developmental Psychology: Midlife and Later Years in Western and Non-Western Societies
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
Regulation of the RNA‐binding protein Smaug by the GPCR Smoothened via the kinase Fused
From fly to mammals, the Smaug/Samd4 family of prion-like RNA-binding proteins control gene expression by destabilizing and/or repressing the translation of numerous target transcripts. However, the regulation of its activity remains poorly understood. We show that Smaug's protein levels and mRNA repressive activity are downregulated by Hedgehog signaling in tissue culture cells. These effects rely on the interaction of Smaug with the G-protein coupled receptor Smoothened, which promotes the phosphorylation of Smaug by recruiting the kinase Fused. The activation of Fused and its binding to Smaug are sufficient to suppress its ability to form cytosolic bodies and to antagonize its negative effects on endogenous targets. Importantly, we demonstrate in vivo that HH reduces the levels of smaug mRNA and increases the level of several mRNAs downregulated by Smaug. Finally, we show that Smaug acts as a positive regulator of Hedgehog signaling during wing morphogenesis. These data constitute the first evidence for a post-translational regulation of Smaug and reveal that the fate of several mRNAs bound to Smaug is modulated by a major signaling pathway.Fil: Bruzzone, Lucia.

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?
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
