Using motion cues to enhance vessel contrast is a powerful tool for visualizing the capillary network, in the absence of contrast agents. The authors demonstrate a tool to study the microcirculation of healthy subjects noninvasively.

This study represents the first attempt to study sexual jealousy in a random community sample. Jealousy was reported by all subjects. Men, when jealous, were particularly concerned about the potential loss of the partner, whereas women were more concerned with the effects of infidelity on the quality of the relationship. Behaviours such as searching the partner's belongings or inspecting their clothes for signs of sexual activity correlated with unusually intense jealousy. Men tended to cope with jealousy by using denial and avoidance, whereas women were more likely to express their distress and to try to make themselves more attractive to their erring partner. Greater jealousy concerns were expressed by young men who had either married early or were now living without a partner. Heavy drinkers and those reporting more psychiatric symptoms were also more prone to jealousy. A clear correlation emerged between lowered self-esteem and increased jealousy, which was particularly marked in women, for whom robust self-esteem was virtually incompatible with high jealousy concerns. The study supported the prosaic notion that those who are satisfied with their romantic attachments are less prone to jealous suspicions. This study offers a starting point for the clinician seeking information about the experience of jealousy in the community.

We examined the structural validity, internal consistency (alpha and omega), and test-retest reliability of scores on the Cross Racial Identity Scale (CRIS; Vandiver et al., 2000 ; Worrell, Vandiver, & Cross, 2004 ), as well as the relationship between CRIS scores and several variables related to psychological adjustment. Participants consisted of several groups of African American college students (34 ≤ n ≤ 340) attending a predominantly White university in a Western state. Confirmatory factor analyses indicated an acceptable fit of the data to the theoretical model, and alpha and omega coefficients indicate that CRIS scores have moderate to high internal consistency. CRIS scores also demonstrated stability over periods between 2 and 20 months in ranges that suggest long-term stability of racial attitudes. As predicted by the expanded nigrescence model (Cross & Vandiver, 2001 ), only self-hatred attitudes had consistent, meaningful relationships with psychological adjustment.
