The relationship of perceptions and emotions to behavior in the face of collective inequality

The present experiment investigated the role of emotions and perceptions in determining the overt behavior of disadvantaged group members. Three limitations to the existing psychological research are presented as a possible reason for the present inability to describe a consistent relationship between the emotions and perceptions of those faced with intergroup inequalities and their subsequent actions. The present experiment attempted to address these limitations by employing a laboratory paradigm in which subjects actually engage in overt behavior. As well, a broader array of emotions and perceptions were assessed and subjects were offered a variety of behaviors from which to choose. The findings point to a relatively strong relationship between emotions and perceptions on the one hand, and overt action on the other. Feelings of frustration and anger, the perception of one's personal treatment as satisfactory and just, and hope of future improvement of one's position combined to discriminate between subjects who accepted their disadvantaged position, those who took normative forms of action, those who reacted in an individual nonnormative way, and those who chose collective nonnormative behavior.     

A comparative study of analytical methods to determine postmortem changes in carbon monoxide concentration

Twenty-one autopsy blood samples were analyzed using spectrophotometric and gas chromatographic procedures after storage for 30 and 150 days.When carboxyhemoglobin was measured spectrophotometrically at the absorbance ratio of $\text{540}\text{nm}\text{555}\text{nm}$, the observed average percent losses were 8 ± 9% and 35 ± 27% after 30 and 150 days of storage, respectively. When measured at the absorbance ratio of $\text{540}\text{nm}\text{579}\text{nm}$, the average percent losses of carboxyhemoglobin were 7 ± 8% and 34 ± 25% after 30 and 150 days, respectively. Wavelength shifts and distorted spectral scans were observed at 150 days.When carbon monoxide was determined by gas chromatographic methods based on combining capacity, the average percent loss was 15 ± 24% and 37 ± 36% after 30 days and 150 days, respectively. The average percent loss of calculated CO based on hemoglobin concentration after 30 days was 31 ± 14% and at 150 days, 40 ± 24%. The average percent loss of calculated CO based on iron content was 23 ± 13% and 37 ± 23% after 30 and 150 days, respectively.
