RESUMEN
Correction for 'Cucurbit[7]uril inclusion complexation as a supramolecular strategy for color stabilization of anthocyanin model compounds' by Barbara Held, et al., Photochem. Photobiol. Sci., 2016, DOI: 10.1039/c6pp00060f.
RESUMEN
Host-guest complexation with cucurbit[7]uril of anthocyanin model compounds in which acid-base equilibria are blocked resulted in essentially complete stabilization of their color. The color protection is a thermodynamic effect and establishes a strategy to stabilize these colored compounds at pH values of interest for practical applications.

We use data from the 2006 American Community Survey to examine race and ethnic differences in the effects of marital status and co-residence of the middle generation on the likelihood of poverty among grandfathers who have primary responsibility for co-resident grandchildren (N = 3,379). Logistic regression results indicate that race/ethnicity and household composition are significant predictors of poverty for grandfather caregivers: non-Hispanic white grandfathers, those who are married, and those with a co-resident middle generation are the least likely to be poor. The effects of race/ethnicity, marital status, and the presence of a middle generation are, however, contingent upon one another. Specifically, the negative effect of being married is lower among grandfathers who are Hispanic, African American, non-Hispanic, and non-Hispanics of other race/ethnic groups compared to whites. In addition, having a middle generation in the home has a larger negative effect on poverty for race/ethnic minority grandfathers than for non-Hispanic whites. Finally, the combined effects of marriage and a middle generation vary across race/ethnic group and are associated with lower chances of poverty among some groups compared with others. We use the theory of cumulative disadvantage to interpret these findings and suggest that race/ethnicity and household composition are synergistically related to economic resources for grandfather caregivers.

OBJECTIVE: Our purpose was to determine whether administering the anti-inflammatory agent ketorolac after abdominal myomectomy reduces the incidence of febrile episodes. STUDY DESIGN: This prospective, randomized, double-blinded, placebo-controlled clinical investigation compared administering ketorolac 15 mg intravenously every 6 hours beginning in the recovery room with saline solution administered in the same regimen in 122 patients undergoing abdominal myomectomy in a large, urban academic medical center. The primary outcome was fever >101.0 degrees F in the postoperative period. Results were analyzed by chi(2) analysis, independent samples t test, and logistic regression. RESULTS: Data were analyzed on 112 patients, with 56 in the treatment group and 56 in the placebo group. After confounding factors were controlled with logistic regression, the data revealed a statistically significant reduction in febrile episodes in the ketorolac-treated group (27%) compared with the saline solution-treated group (41%) (P =.04). CONCLUSION: Treatment with ketorolac after abdominal myomectomy results in a statistically significant reduction in the rate of febrile episodes.

According to both popular and professional indicators, the push for the positive attitude in America is on the rise. After considering the popular culture zeitgeist, I compare and contrast two recent professional psychology movements-those of positive psychology and postmodern therapy-both of which rest on a foundation of optimism and positive thinking despite their opposing views about a proper philosophy of science. I then present cross-cultural empirical research that calls into question the typical (North American) assumption that a positive attitude is necessary for (a sense of) well-being. I also consider findings in health psychology, clinical/counseling psychology, and organizational behavioral science, findings which call into question the assumption that accentuating the positive (and eliminating the negative) is necessarily beneficial in terms of physical and mental health. The clinical/therapeutic implications of this analysis are addressed, as I put forth my conjecture about the existence of what I call the "tyranny of the positive attitude" in the form of a question: If there indeed now exists unprecedented pressure to accentuate the positive, could it then be that the pressure itself to be happy and optimistic contributes to at least some forms of unhappiness?

The attitudes and behaviors examined in this special section-namely, negativity, complaining, pessimism, and "false" hope-have not typically been viewed as virtuous either in popular culture or in professional psychology. In reconsidering these attitudes and behaviors, each of the authors demonstrates how there may actually be virtue, or at least something positive, in what has typically been cast in a negative light.
