Understanding the needs and challenges of a Black community in South Africa

This article reports on a study conducted with an unemployed group of community members residing in the Gugulethu Township in South Africa. The study aimed to gain an in-depth understanding of their needs and challenges, and what they thought could be done to assist and empower them so that they could improve their lives. Their basic human needs were violated during apartheid and as a consequence, they are still battling poverty today. We offer suggestions on how Black communities in South Africa could be supported and empowered in order to become employable and self-reliant.     

FACTORS THAT ENHANCE OR CURTAIL THE SOCIAL FUNCTIONING OF FEMALE SINGLE PARENTS

Explored in this study of 67 women who have been divorced for 2 or more years are the factors enhancing or limiting the social functioning of these individuals. The path analysis identifies such factors as duration of marriage, number of children, involvement of ex-spouse, and family support as determinants of postdivorce adjustment.     

Morphology of bullet wounds when using police ammunition, type QD-P.E.P

6 years after introduction of the police ammunition QD-P.E.P. (9 mm caliber), 9 bullet wounds are presented from forensic investigations along with the results of experimental shots at pig carcasses. The evaluation reveals the characteristic pattern of such bullet wounds: a skin defect which is almost as large as the caliber and has a sharp-edged border thus looking like it has been punched out; the contusion ring ("abrasion ring") is conspicuously narrow. These findings can be explained by the shape and design of the projectile. In regular police work immediate incapacitation has not always been achieved, depending on the entry location of the bullet. Experimental shots at pig carcasses showed that in the case of shots at extremities, the residual energy of the exiting bullet may be sufficient to generate another penetrating bullet wound.     

Oral fluid testing for cannabis: on-site OraLine IV s.a.t. device versus GC/MS

Saliva or "oral fluid" has been presented as an alternative matrix to document drug use. The non-invasive collection of a saliva sample, which is relatively easy to perform and can be achieved under close supervision, is one of the most important benefits in a driving under the influence situation. Moreover, the presence of Delta9-tetrahydrocannabinol (THC) in oral fluid is a better indication of recent use than when 11-nor-Delta9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH) is detected in urine, so there is a higher probability that the subject is experiencing pharmacological effects at the time of sampling. In the first part of the study, 27 drug addicts were tested for the presence of THC using the OraLine IV s.a.t. device to establish the potential of this new on-site DOA detection technique. In parallel, oral fluid was collected with the Intercept DOA Oral Specimen Collection device and tested for THC by gas chromatography mass spectrometry (GC/MS) after methylation for THC (limit of quantification: 1 ng/mL). The OraLine device correctly identified nine saliva specimens positive for cannabis with THC concentrations ranging from 3 to 265 ng/mL, but remained negative in four other samples where low THC concentrations were detected by GC/MS (1-13 ng/mL). One false positive was noted. Secondly, two male subjects were screened in saliva using the OraLine and Intercept devices after consumption of a single cannabis cigarette containing 25mg of THC. Saliva was first tested with the OraLine device and then collected with the Intercept device for GC/MS confirmation. In one subject, the OraLine on-site test was positive for THC for 2 h following drug intake with THC concentrations decreasing from 196 to 16 ng/mL, while the test remained positive for 1.5 h for the second subject (THC concentrations ranging from 199 to 11 ng/mL). These preliminary results obtained with the OraLine IV s.a.t. device indicate more encouraging data for the detection of THC using on-site tests than previous evaluations.
