Scientific coats of arms

With their mythical creatures and arcane symbolism, coats of arms seem to have little connection with modern science. Yet despite its chivalric origins, the ancient language of heraldry has long fascinated famous scientists. Although this idiosyncratic tradition was parodied by Victorian geologists, who laughingly replaced unicorns and griffins with images of dinosaurs that they had recently discovered, it has been perpetuated since by Ernest Rutherford, who liked to present himself as a new alchemist.

Appendix B: Potential Effects on Children's Performance of Features of the Research Design

In addition to the variables of interest in this research (namely, age, delay, sequence type, mode of experience, and verbal reminders), children's performance may have been affected by a number of features of the research design. This Appendix is a report of the results of analyses of three potential influences on the children's performance. First, we examined the possibility that the particular experimenter who conducted the session might have affected the children's performance. Second, we examined the possibility that conclusions regarding children's recall of the event sequences were qualified by specific event sequence effects. Third, we examined the possibility that differences in the lengths of the child-controlled response periods might account for the patterns of effects observed. Although in each case some effects obtained, in no case did the findings present substantive qualifications to the major patterns described in the body of the text.     

Long-term effects of child punishment on Mexican women: a structural model

OBJECTIVE: The aim of this study was to investigate long-term effects of parental use of physical and verbal punishment on Mexican women. To study both direct and indirect effects of these phenomena, a structural model was developed and tested. METHOD: One hundred and fifty Mexican women were interviewed with regard to their history of child abuse, their level of depression, alcohol use, antisocial behavior, and punishment of their own children. Factors representing such constructs were specified within a structural equation model and their inter-relations were estimated. Women's history of abuse was considered as an exogenous latent variable directly affecting three other factors: mothers' antisocial behavior, their alcohol consumption, and their levels of depression or anxiety. These factors, in turn, were specified as influencing mothers' harsh discipline of their own children. RESULTS: Data supported this model, indicating that a history of abuse has long-term effects on women's behavior and psychological functioning, which in turn cause women's punitive behavior against their children. CONCLUSIONS: These results are discussed in terms of the theoretical framework of intergenerational transmission of violence. The direct consequences (depression, anxiety, alcohol consumption, and antisocial behavior) of child punishment act as risk factors for the next generation of child abuse.
