Report of the panel on lithospheric structure and evolution, section 3

The panel concluded that NASA can contribute to developing a refined understanding of the compositional, structural, and thermal differences between continental and oceanic lithosphere through a vigorous program in solid Earth science with the following objectives: determine the most fundamental geophysical property of the planet; determine the global gravity field to an accuracy of a few milliGals at wavelengths of 100 km or less; determine the global lithospheric magnetic field to a few nanoTeslas at a wavelength of 100 km; determine how the lithosphere has evolved to its present state via acquiring geologic remote sensing data over all the continents

Racial/Ethnic differences among smokers: revisited and expanded to help seekers

Most research on racial/ethnic differences among smokers is outdated and does not focus on help seekers. The purpose of this study was to revisit racial/ethnic differences in variables related to cessation in a sample of smokers enrolled in a randomized trial. Adult smokers (N = 417; n = 126 White; n = 123 Hispanic; n = 168 Black) completed measures of demographics, smoking history, alcohol use, depressive symptoms, and readiness to quit. We found significant differences in these factors across groups. Blacks were more likely to be older, less educated, single, low income, smoke menthol cigarettes, and report greater nicotine dependence. Hispanics were younger, reported fewer years smoking and cigarettes per day, lower nicotine dependence, preferred mentholated cigarettes, and reported greater alcohol use intensity. After controlling for demographics and smoking history, Blacks reported greater depressive symptoms and lower readiness to quit compared with Whites and Hispanics. Help-seeking Blacks may exhibit more risk factors for difficulty quitting compared with other groups. Hispanics may have some protective factors, such as lower dependence, but require attention to alcohol use and menthol smoking. Identifying preintervention racial/ethnic differences in characteristics related to cessation is important for developing evidence-based and culturally specific interventions and for reducing tobacco-related health disparities

Associations between coping, affect, and social support among low-income African American smokers

Previous research has documented disparities in smoking cessation between African Americans and Caucasians. Many low-income African American smokers face a range of circumstances that may inhibit effective coping during quit attempts, yet previous research has not considered factors that influence coping in this population. This study examined (a) affect (positive and negative) and (b) perceived social support in association with coping strategies. The baseline assessment of African American smokers (N=168) enrolled in a randomized controlled trial included the Positive and Negative Affect Schedule, the Multidimensional Scale of Perceived Social Support, and the Brief COPE. A factor analysis of the Brief COPE resulted in two factors, adaptive and maladaptive strategies. Participants were mostly single (64%), women (61%), with ≥12years of education (68%), and low-income. They were middle aged (M=46.1, SD=8.7), smoked 21.8 (SD=13.3) cigarettes/day for 24.3 (SD=11) years, and were moderately nicotine dependent. Results demonstrated that adaptive coping was positively correlated with positive affect and social support. Maladaptive coping was positively correlated with negative affect, and inversely related to positive affect and social support. Multivariate analyses revealed that positive affect and social support were independently associated with adaptive coping strategies. In contrast, maladaptive coping was independently associated with negative affect, but not social support. Interventions that harness positive resources, such as social support and positive mood, may facilitate adaptive coping. Also, addressing negative affect among low-income African American smokers may be important to reduce maladaptive coping strategies. •Examined correlates of coping strategies among low-income African American smokers.•Positive affect and social support were independently related to adaptive coping.•Negative affect was related to the use of maladaptive coping strategies.•Knowledge of factors associated with coping can inform cessation interventions

Culturally specific versus standard smoking cessation messages targeting Hispanics: An experiment

Few smoking cessation trials have focused on U.S. Hispanics. Consequently, little is known about culturally specific considerations for intervention delivery. The purpose of this study was to test the efficacy of a written smoking cessation intervention varying in cultural specificity and language. Participants (N = 222) were English-Spanish bilingual Hispanic smokers recruited from the community. A 2 (cultural specificity-culturally specific or standard) × 2 (receipt of preferred language materials-preferred or less preferred) between-subjects experiment was conducted. Participants were assessed at baseline and at a 2-week post intervention follow-up. Dependent variables measured intervention evaluations (intended utilization and content evaluation), cigarettes smoked per day, and smoking cessation (secondary outcome). We hypothesized independent effects of cultural specificity, receipt of preferred language materials, and an interaction effect. Results demonstrated that intended utilization was greater among participants who received the intervention in their preferred language, F(1, 213) = 9.772, p = .002, η2 = .044. No differences in content evaluations were observed. However, number of cigarettes smoked per day was lower, and self-reported cessation was significantly greater among participants who received a culturally specific intervention, F(1, 152) = 4.939, p = .028, partial η2 = .031, and materials in their preferred language, OR = 5.356, p = .037, 95% CI [1.106, 25.948], respectively. In conclusion, this study contributes to our understanding of dimensions influencing responses to smoking cessation interventions among Hispanics. Both cultural specificity and preferred language delivery appear to be causally related to the intended utilization of interventions and smoking behavior. (PsycINFO Database Recor
