Specimens were repeatedly obtained for mycological examination from the skin, throat, urine, and feces of the six astronauts who conducted the Apollo 14 and Apollo 15 lunar exploration missions. Analysis of preflight data demonstrates that the process of severely restricting opportunities from colonization for 3 weeks before flight resulted in a 50% reduction in the number of isolated species. Postflight data indicate that exposure to the space flight environment for up to 2 weeks resulted in an even greater reduction with a relative increase in the potential pathogen Candida albicans. No incidences of microbial shock were observed when crewmembers were quarantined for 16 days after completion of the space flight. Intercrew transfer of particular species could not be demonstrated because most species were not consistently recovered.
A sample of 498 sexually active first-year students matriculating at a historically Black college in North Carolina was used to determine correlates of risky sexual behaviors. In an Ordinary Least Squares regression, the self-esteem element "I take a positive attitude toward myself" (B = 1.12, p = .05), non-condom use because of partner issues (B = .53, p = .05) and being drunk or high (B = 1.20, p = .001), oral sex (B = 1.74, p = .001), anal sex (B = .61, p = .04), and bisexuality (B = .85, p = .03) all increased the number of these behaviors. Higher scores on the condom usage scale (B = -.38, p = .002) were found to decrease the number of risky sexual behaviors. Illicit drug use was an underpinning of the surprisingly positive relationship between positive self-image and risky sexual behaviors. It was concluded that school-based social workers, mental health care professionals, and community-based prevention providers can play a critical role in the training of peer facilitators, development, and supervision of peer-driven risk-reduction programs to address the complex interplay among self-esteem, sex, and substances.
+ + 4-+ , marked homogenous erythema ; +++, homogenous erythema; ++, patchy erythema; +, slight erythema; 01, no reaction.An additional designation of t to indicate minimal reaction has been added.After reading of skin tests, hair was clipped from the $abdominal surface and 15 nd of sterile light minleral oil was injected intraperitoneally to evokle exudabive cells. Seventytwo b u r s after oil injection, animals were exsianguinated by inkracardial puncture, and peritoneal exudate cells were collected. For this collection, the abdominal wall was opened and the cavity washed 3 times with s t d eHanks balanced salt solution ( 1 1 ) , modified by the addition of 0.1% gelatin.
In the United States, the digital divide exists, which is a gap between people with access to technology and those who do not have access. The African American community is far behind Whites in terms of computer and Internet usage. Many advocates of Historically Black Colleges and Universities (HBCUs) are concerned about the existence of a digital divide between predominantly White colleges and HBCUs. This study reports technology scores for the faculty of a small Southern HBCU on its familiarity and use of technology. Furthermore, the study focuses on how the college administrators addressed technology issues on the campus over a 3-year period following the initial faculty technology survey. Recommendations are shared to enable HBCUs to compete and thrive technologically.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
