Exploring risk and protective mechanisms associated with HIV infection among adolescents in South Africa

This study explored South African adolescents’ perceived risk and protection for HIV infection. Adolescents (N=28) with a mean age of 14.6 years receiving mental health care participated in Focus Group Discussions (FGDs) to engage in an in-depth exploration of their perceived risk and protective mechanisms for HIV prevention. The data were analysed using thematic content analysis. Themes that emerged from the FGDs associated with risk for HIV infection were: Alcohol and illicit drug use; Non-condom use; Prostitution and risky sexual activity with multiple partners; and Non-disclosure of HIV status. Themes that emerged as protective mechanisms included: HIV knowledge and appropriate HIV risk reducing behaviour; and Proactive parental attitudes and behaviour. These findings highlight the importance of ascertaining the perceptions of adolescents about risk and protection from HIV infection in order to inform future programs for HIV prevention among adolescents.     

On behalf of the consequence argument: time, modality, and the nature of free action

The consequence argument for the incompatibility of free action and determinism has long been under attack, but two important objections have only recently emerged: Warfield’s modal fallacy objection and Campbell’s no past objection. In this paper, I explain the significance of these objections and defend the consequence argument against them. First, I present a novel formulation of the argument that withstands their force. Next, I argue for the one controversial claim on which this formulation relies: the trans-temporality thesis. This thesis implies that an agent acts freely only if there is one time at which she is able to perform an action and a distinct time at which she actually performs it. I then point out that determinism, too, is a thesis about trans-temporal relations. I conclude that it is precisely because my formulation of the consequence argument emphasizes trans-temporality that it prevails against the modal fallacy and no past objections.     

Testing Deterrence Theory with Offenders: The Empirical Validity of Stafford and Warr's Model

Stafford and Warr (1993) reconceptualized general and specific deterrence into a single theory in which individuals' propensities to engage in crime are based on a combination of personal and vicarious experiences with being punished and avoiding punishment. The current study extends prior tests of this conceptualization of deterrence by expanding the definition of vicarious experience, analyzing extralegal as well as legal consequences, examining multiple types of offending behavior, and drawing its data from a sample of work release facility inmates. The results fail to support legal deterrence as an explanation of offending for this sample but suggest the importance of extralegal consequences.     

Examining the role of social cues in early word learning

Infants watched a video of an adult pointing towards two different objects while hearing novel labels. Analyses indicated that 14- and 18-month-olds looked longer at the target object, but only 18-month-olds showed word learning. The results suggest that different types of social cues are available at different ages.     

Effectiveness of follow‐up reminiscence therapy on autobiographical memory in pathological ageing

The objective is to examine the effects of reminiscence therapy (RT) on total, episodic and semantic autobiographical memory in amnestic mild cognitive impairment (aMCI) and Alzheimer's disease (AD) groups, testing the effects of RT on different stages of autobiographical memory, and its effectiveness at follow‐up. A sample composed of 43 aMCI (27 treatments, 16 controls) and 30 AD (15 treatments, 15 controls) subjects were evaluated with the Autobiographical Memory Interview (AMI) test. The RT consisted of 10 sessions lasting 60 minutes each. Both groups, aMCI and AD, showed significant effects on overall autobiographical memory; aMCI showed significant main effects on episodic and semantic autobiographical memory in the treatment group, increasing scores in both cases. For AD, significant effects were observed on autobiographical episodic memory, showing an increase in the treatment group from Time 1 to follow‐up; semantic memory showed a decrease in the control group from Time 1 to follow‐up. Results show that RT implementation and follow‐up are effective in increasing autobiographical memory in subjects with aMCI and AD.     

The Role of Recollection and Familiarity in Nondemented Parkinson's Patients

The aim of the current study was to examine if recollection and familiarity decline in nondemented Parkinson's patients. To do so we compared a sample of older people with Parkinson's disease (n = 32) to a control sample of healthy older people (n = 32) on an associative recognition task in which we manipulated the repetition of the pairs during the study phase (half of the pairs were presented once and half twice) to obtain corrected estimates of recollection, familiarity, and false recognition based on the logic of the process-dissociation procedure. The results clearly show that recollection is impaired but familiarity is preserved in nondemented Parkinson's patients. The results show that memory for pairs in Parkinson's patients relies largely on the familiarity of each item and not on a precise recollection of associative information, supporting the idea that recollection-based monitoring processes are impaired in these patients.     

Death Qualification as Systematic Exclusion of Jurors With Certain Religious and Other Characteristics

The death‐qualification process has been criticized because it tends to eliminate certain groups of individuals at a higher rate than others. This study examined whether the process systematically excludes jurors based on religious characteristics, justice philosophy, cognitive processing, and demographics. Results indicated that death qualification can be predicted by religious affiliation, devotionalism, fundamentalism, and Biblical interpretism; but not evangelism. Death qualification is predicted by the belief that murderers deserved to die, but not by beliefs that criminals deserve mercy, forgiveness, or payback. Cognitive processing had no impact on death qualification. Finally, gender and race predicted death qualification, while age and prior jury duty did not. These results are discussed in terms of implications for perceived legitimacy of the system.     

NATURALIZING TRANSCENDENCE IN THE NEW COSMOLOGIES OF EMERGENCE

Abstract. Recent discourse on emergence within the natural sciences offers a superior alternative to traditional notions of transcendence. Emergence is a term of common parlance in the natural sciences. It designates moments when various systems develop an internal dynamic that generates an entirely new level of complexity, a qualitatively different mode of existence that cannot simply be reduced to its constituent parts. To the natural scientist, emergence is an expression of transcendence without reference to final causality or central organizing principle. Autopoietic emergence is more congruent with contemporary understandings of the universe than the traditional anthropomorphizing concept of teleological design. In this article I offer both an interpretation of emergence as a new category for the interpretation of divinity and an explanation for traditional anthropomorphism rooted in contemporary cognitive sciences.
