Stigma, Culture, and HIV and AIDS in the Western Cape, South Africa: An Application of the PEN-3 Cultural Model for Community-Based Research

HIV- and AIDS-related stigma has been reported to be a major factor contributing to the spread of HIV. In this study, the authors explore the meaning of stigma and its impact on HIV and AIDS in South African families and health care centers. They conducted focus group and key informant interviews among African and Colored populations in Khayelitsha, Gugulethu, and Mitchell's Plain in the Western Cape province. The audio-recorded interviews were transcribed and coded using NVivo. Using the PEN-3 cultural model, the authors analyzed results showing that participants' shared experiences ranged from positive/nonstigmatizing, to existential/unique to the contexts, to negative/stigmatizing. Families and health care centers were found to have both positive nonstigmatizing values and negative stigmatizing characteristics in addressing HIV/AIDS-related stigma. The authors conclude that a culture-centered analysis, relative to identity, is central to understanding the nature and contexts of HIV/AIDS-related stigma in South Africa.     

Persuasive Appeals and the Reduction of Skin Cancer Risk: The Roles of Appearance Concern, Perceived Benefits of a Tan, and Efficacy Information

This experiment compared the effectiveness of appearance-based messages focusing on the benefits of tanning and the efficacy of preventive measures on students' intentions to protect themselves against sun-induced skin damage. Subjects who were high or low on a dispositional measure of appearance concern responded to 1 of 4 essays providing either high or low benefits information, and high or low efficacy information. Overall, subjects low in appearance concern expressed greater intentions to take precautionary measures than did those high in appearance concern. Additionally, the low benefits of tanning message produced greater intentions to take precautions than did the high benefits message. The benefits results suggest 1 mechanism through which sun protection behaviors may be encouraged.     

Sequential contrast effects with human subjects

Institutionalized retardates were exposed to a multiple variable-interval: extinction schedule of reinforcement in which 5-min periods of variable-interval reinforcement and 5-min periods of extinction were presented in a random order. This schedule was found to generate sequential contrast effects: response rates during variable-interval reinforcement were higher when a variable-interval period followed an extinction period than when it followed another variable-interval period. The rate of responding within a variable-interval period also was affected by the number of extinction periods preceding a variable-interval period. As the number of successive extinction periods that preceded a variable-interval period increased, the rate of responding during that variable-interval period increased. The sequential contrast effects were transient, being most evident during the early sessions and generally disappearing by the tenth session.     

Interpersonal issues in counselling a resistant child: A case-study

A therapeutic relationship was established with a resistant child whose experiential background together with the ongoing uncertainty of her life situation created interpersonal issues which threatened the continuance of counselling. The case-study focuses on the aims of counselling and how these were handled within the oscillating relationship that was developed between counsellor and child.     

The Power of Feelings

Abstract

The relationship between myth, the dream, narrative and career are explored in order to understand better the underlying factors that influence career development and will thus inform the work of career counsellors. A case study is used to illustrate how these insights can be used in practice.     

Cognitive Development of Lead Exposed Children from Ages 6 to 15 Years: An Application of Growth Curve Analysis

The effect of lead exposure on cognitive growth patterns was assessed in a longitudinal study of 196 children. Performances on tests of verbal comprehension and perceptual organization (Vocabulary & Block Design, Wechsler Intelligence Scales for Children) were measured at ages 6.5, 11 and 15 years. Growth curve analyses revealed that the quadratic model best described the relationship between test scores and age. Children with higher lead levels, as measured at age 15 years, demonstrated lower verbal comprehension scores over time and greater decline in their rate of Vocabulary development at age 15 years, as compared to children with lower lead levels. Lead exposure was not significantly associated with growth in perceptual organization test scores. Socioeconomic status and maternal intelligence were statistically significantly associated with growth patterns for both test scores, independent of the effects of lead. The findings suggest that lead negatively impacts the developmental progression of specific cognitive skills from childhood through adolescence.
