A Nelsonian Response to ‘the Most Embarrassing of All Twelfth-century Arguments’

Alberic of Paris put forward an argument, ‘the most embarrassing of all twelfth-century arguments’ according to Christopher Martin, which shows that the connexive principles contradict some other logical principles that have become deeply entrenched in our most widely accepted logical theories. Building upon some of Everett Nelson’s ideas, we will show that the steps in Alberic of Paris’ argument that should be rejected are precisely the ones that presuppose the validity of schemas that are nowadays taken as some of the most trivial logical truths: (A∧B) →_AB A and (A∧B) →_AB B, i.e. Simplification.     

Understanding Suicide in Socially Vulnerable Contexts: Psychological Autopsy in a Small Town in Mexico

In Mexico, suicides are increasing in certain latitudes where local rates have grown to levels of alert; suicide is also the second most common cause of death for the group aged 15 to 19. The psychological autopsy method was utilized to uncover and analyze common factors in all of the registered suicides within 2011 and 2012 in a small town of the state of Guanajuato, located in the center of Mexico. A total of nine decedents were analyzed, and 22 interviews were conducted. The most salient factors were as follows: poverty, financial stress, substance abuse, low levels of education, conflictive relationships, and a poor handling of emotions. The concepts of social exclusion and vulnerability were employed to analyze suicides as symptoms of a much deeper problem of this country, suggesting that anomie and social malady are nowadays important suicidal factors, mostly for children and young people.     

Does surgency moderate the relationship between parenting and children's aggression in middle childhood?

Parenting and child temperament have both been linked to aggression among children. This study explores the moderating effects of children's surgency and sex and paternal/maternal parenting practices on aggressive behaviour in middle childhood. We analyse whether the moderating effects observed fit a Diathesis-Stress, Differential Susceptibility or Vantage Sensitivity model. Participants were 203 school children aged 7–8 years (M = 92.42 months, SD = 3.52) from southern Spain. Maternal inconsistency and coercion and paternal hostility and indulgence, had a direct effect on children's aggressive behaviour. The effects of maternal hostility and anticipatory problem solving on children's aggression were moderated by surgency (Diathesis-Stress), as was the effect of paternal coercion on aggression (Vantage Sensitivity). Children's sex was not found to moderate any effect. It therefore seems that not all children are equally sensitive to the influence of parenting on their aggression levels, and that this influence depends on their temperament.

Highlights

• This study explores the moderating effects of children's surgency and sex and paternal/maternal parenting practices on aggressive behavior.
• Children's surgency moderated the effect of maternal hostility and anticipatory problem solving on children's aggression, with both effects fitting a Diathesis-Stress model.
• Children's surgency moderated the effect of paternal coercion on children's aggression, with this effect fitting a Vantage Sensitivity model.
