Dislocation formation in the partially coherent interfaces of an embedded layer in a semi-infinite matrix

The formation of two misfit edge dislocations is theoretically investigated in the interfaces of a layer embedded in a semi-infinite matrix. Assuming the matrix–layer interfaces are partially coherent, the energy variation resulting from the formation of the dislocations from the lateral free surface of the structure has been determined in the shearing stress field due to the partial misfit. The mechanical stability of the structure is analysed with respect to the dislocation formation as a function of the size of the coherent region of the interface and the misfit strain.     

Sex,strain, and housing: Variables influencing the effects of prior shock exposure on shock-induced aggression

A series of experiments was conducted to investigate sex, housing conditions, and strain as possible factors influencing the interference effect of prior exposure to shock on shock-induced aggression. In albino subjects, female rats and rats housed in community cages evidenced the greatest suppression in aggression following prior exposure to shock. In addition, ten sessions of prior exposure to shock produced a greater suppression in shock-induced fighting than 20 sessions of prior exposure to shock. The prior shock effect was not obtained with hooded subjects. Responsivity to shock was also investigated to determine whether the prior exposure to shock attenuation of shock-induced fighting was a consequence of reduced activity in response to shock. Responsivity to shock measured with an isometric platform accounted for less than 4% of the variance in shock-induced fighting in the single experiment that obtained a correlation between responsivity and shock-induced aggression.     

Expressive suppression and financial risk taking: A mediated moderation model

This research aimed to investigate the relationship between the habitual use of expressive suppression, a type of emotion regulation strategy, and risk taking in the financial domain. It also attempted to further examine gender as a possible moderator of this relationship and to explore the anticipated emotion related to negative potential outcomes as the mechanism behind this moderated effect. Two studies were conducted for these purposes. In Study 1, a total of 657 college students completed a test battery, including both the Emotion Regulation Questionnaire and the Grable and Lytton Risk Tolerance Scale. The results showed that expressive suppression was negatively related to financial risk taking, and gender moderated this relationship. In Study 2, 441 college students took a test battery including both the Emotion Regulation Questionnaire and a financial investment allocation task. The results replicated the findings in Study 1 and indicated that the anticipated emotion related to negative potential outcomes fully mediated the moderated effect of gender in the suppression-financial risk taking association. These findings implied the importance of considering gender differences in the prediction of financial choices from the perspective of emotion regulation.
