Abstract:
Fighting and dying, or what Whitehouse calls "out-group hostility" and "extreme self-sacrifice," are not conceptually overlapping, but in fact are highly distinguishable, both theoretically and empirically. I present empirical evidence from a reanalysis of Ginges et al. (2009, Study 4), demonstrating the potentially inverse relationship between "parochial hostility" - fighting and "sacrificial altruism" - "and" dying.

Graphical and Analytic Representation of Sinusoids
The first step is measuring the peak-to-peak value, which is twice the amplitude of the sinusoid. This provides information about the maximum voltage swing of the waveform.
Secondly, the period and angular frequency are determined. The period is the time taken for one complete cycle of the waveform, while...
