Acculturative Stress among Documented and Undocumented Latino Immigrants in the United States.

Abstract: The purpose of the study was to examine differences between documented and undocumented Latino immigrants in the prevalence of three immigration-related challenges (separation from family, traditionality, and language difficulties), which were made more severe after the passage of restrictive immigration legislation in 1996. Specifically, the study sought to determine the combined and unique associations of legal status, the three immigration-related challenges listed above, and fear of deportation to acculturative stress related to family and other social contexts. Participants in the study consisted of 416 documented and undocumented Mexican and Central American immigrants living in two major cities in Texas. The Hispanic Stress Inventory-Immigrant form was used to assess acculturative stress in the sample. Results indicated that although undocumented immigrants reported higher levels of the immigration challenges of separation from family, traditionality, and language difficulties than documented immigrants, both groups reported similar levels of fear of deportation. Results also indicated that the immigration challenges and undocumented status were uniquely associated with extrafamilial acculturative stress but not with intrafamilial acculturative stress. Only fear of deportation emerged as a unique predictor of both extrafamililal and intrafamilial acculturative stress.

Assessing the Relative Informativeness and Permanence of Pro Forma Earnings and GAAP Operating Earnings

Abstract: This study investigates whether market participants perceive pro forma earnings to be more informative and more persistent than GAAP operating income by analyzing a sample of 1,149 actual pro forma press releases. We find that pro forma announcers report frequent GAAP losses and are mostly concentrated in the service and high-tech industries. Our analyses of short-window abnormal returns and revisions in analyst' one-quarter-ahead earnings forecasts indicate that pro forma earnings are more informative and more permanent than GAAP operating earnings. Our evidence suggests that market participants believe pro forma earnings are more representative of "core earnings" than GAAP operating income.

Social-cognitive and cognitive correlates of depression in children

Abstract: The present investigation examined depression and its social-cognitive and cognitive correlates in a sample of 108 elementary school children: 36 children in each of grades 1, 4, and 8. Children were classified as depressed and nondepressed according to their scores on the Children's Depression Inventory (CDI). Depression appeared stable over a 3-week time interval. Depressed children reported a higher number of “masking” symptoms, were rated as more depressed by their teachers, and perceived their family environment to be more distressed. As posited, when compared to nondepressed children, depressed children have lower self-esteem, a more depressive attributional style, and more self-control deficits. Further, they have impaired performance on some cognitive tasks (block design, coding digit span) but not all (vocabulary). The prediction that depression would be manifested differently in first-, fourth-, and eighth-graders was not supported.

Heterocycle synthesis via direct C-H/N-H coupling.

Abstract: A method for five- and six-membered heterocycle formation by palladium-catalyzed C-H/N-H coupling is presented. The method employs a picolinamide directing group, PhI(OAc)(2) oxidant, and toluene solvent at 80-120 °C. Cyclization is effective for sp(2) as well as aliphatic and benzylic sp(3) C-H bonds.
