Correlations of normality and nervousness with cardiovascular functions in pointer dogs

Methylphenidate, 0.5 mg/kg, injected intravenously, was used in 10 normal (A line) and 10 genetically nervous (E line) dogs in a blind-design experiment to aid in prediction, from cardiovascular recordings alone, of behavioral normalityversus nervousness. The prediction was 75 per cent correct, based on heart rate (HR), form of the electrocardiogram (EKG), pattern of sinus arrhythmia, and pattern of HR response to methylphenidate. Nervous dogs were found to have slower baseline HR’s, delayed return of HR to baseline after methylphenidate, greater occurrence of baseline EKG abnormalities and much greater frequency of these after methylphenidate. Degree of nervousness was found to correlate rather highly (1)negatively with baseline HR level, (2)negatively with speed of BP response, and (3)positively with frequency of some of the EKG manifestations. These data, indicative of a relative inertness of physiological functions of nervous pointer dogs compared with normal pointers, are consistent with the behavioral and some of the biochemical findings previously reported.

The lntergenerational transmission of family violence: The long-term effects of aggressive behavior

This paper examines the contention that family violence is passed down from generation to generation. The sample was primarily nonclinical and was composed of 14 clients of community guidance clinics and 82 members of a randomly selected control group. The primary hypothesis that individuals who are exposed to a high degree of physical punishment as children are more likely to resort to family violence as adults was supported. Studies of the modeling of aggression were examined to suggest factors which may mediate the hypothesized relationship. It was found that respondents who had grown up in an environment characterized by either low family warmth or high stress in combination with exposure to a high degree of parental punishment were more likely to use physical punishment in their own families. Also, family violence was more likely to be transmitted in same-sex rather than cross-sex linkages.     

JUST WAR THEORIES RECONSIDERED: Problems with Prima Facie Duties and the Need for a Political Ethic

This essay challenges a “meta‐theory” in just war analysis that purports to bridge the divide between just war and pacifism. According to the meta‐theory, just war and pacifism share a common presumption against killing that can be overridden only under conditions stipulated by the just war criteria. Proponents of this meta‐theory purport that their interpretation leads to ecumenical consensus between “just warriors” and pacifists, and makes the just war theory more effective in reducing recourse to war. Engagement with the new meta‐theory reveals, however, that these purported advantages are illusory, made possible only by ignoring fundamental questions about the nature and function of political authority that are crucial to all moral reflection on the problem of war.
