Radiocarbon analysis of dental enamel and bone to evaluate date of birth and death: perspective from the southern hemisphere

Radiocarbon analysis was conducted on dental enamel, cortical bone and trabecular bone from four human adults from Andean Peru with known birth dates and death dates, the latter all falling within the modern bomb-curve period. Radiocarbon results were compared with known tropospheric values from the southern hemisphere. The results demonstrate that dental enamel can provide useful information regarding birth dates in consideration of known formation times of the specific teeth examined if the radiocarbon values fall within the modern bomb-curve period. Trabecular bone radiocarbon values are closer to the tropospheric values at the date of death than are values from cortical bone reflecting relative differences in the rate of bone remodeling in those tissues. Age at death also represents an important factor.     

Adipocere: what is known after over two centuries of research

This paper reviews over two centuries of research focusing on various issues relating to adipocere. Adipocere is a crumbly, soap-like postmortem product that forms from soft tissue in a variety of environments. The timing of the formation and degradation of adipocere depends largely on the environmental circumstances. Once formed, adipocere can persist for hundreds of years, acting as a preservative. In this way, some define it as a process of mummification. This type of persistence can be useful in a forensic context as it can preserve evidence. Sustained interest in adipocere prompted many investigations into the composition and conditions of formation. More recent investigations, aided by technological advances, build upon the knowledge gained from prior studies as well as delve into the chemical composition of adipocere. This in turn provides new information on detection and documentation of constituent substances.     

Between Constitutional Mo(nu)ments: Memorialising Past,Present and Future at the District Six Museum and Constitution Hill

This article explores the powers and potentialities of imaginations of political community at the site of the museum in contemporary South Africa. Taking the District Six Museum (Cape Town) and Constitution Hill (Johannesburg) as the empirical backdrop, I explore the ways in which memorialising practices at these sites bolster or deflate the exaltation of the post-1996 constitutional moment. This argument aligns closely with contemporary discussions by South African constitutional theorists about the role of monumentalism and counter-monumentalism. Indeed, I argue that memorialising techniques employed at the District Six Museum offer a practice of memory-making that resists the fixed and limited boundaries proffered by the new South African constitutional discourse exalted at Constitution Hill. However, my critique does not include a call for a reform of the latter. Instead, I argue that the continuation of monumental memory practices at Constitution Hill, in juxtaposition to counter-monumental practices at District Six, serves a key role in revealing the limits of fixed notions of law and subjectivity in imagining past and future political communities. Drawing on Antonio Negri’s concept of constituent power, I argue that the juxtaposition of monumental and counter-monumental memorial practices exposes the illusion of the division between transcendent Power (potestas) and immanent power (potentia). Finally, I turn to Emilios Christodoulidis’ conception of ‘strategies of rupture’ to consider ways in which this contradiction might be made to ‘persist’ through the site of the museum. Indeed, if the goal is to illuminate the illusion of transcendent power, the juxtaposition of memorialising practices between the two sites (a museological form of ‘tapping of contradiction’) may serve as a platform for the truth of constituent power to be realised.     

The Family Antecedents and the Subsequent Outcomes of Early Puberty

The purpose of this study was to examine both the family antecedents and the outcomes of early puberty, with a particular focus on factors related to family socioeconomic status (SES). The study employed a comprehensive measurement of pubertal development and longitudinal data from the Canadian National Longitudinal Survey of Children and Youth. The sample (N = 8,440; 49% girls) included four cohorts of children who were followed biennially for 10 years, starting from age 4–11 to 14–21 years. Data were drawn at different years of age from these cohorts of children. Girls whose fathers were unemployed were more likely to experience early puberty than those whose fathers were employed. For boys, those living with fathers who had not finished secondary school were more likely to experience early puberty. Early maturing girls tended to engage in smoking and drinking at an earlier age compared with their peers. These findings provide support for psychosocial acceleration theory and suggest that different aspects of low family SES may act as a psychosocial stress for early pubertal maturation in boys versus girls, which may lead to engagement in drinking and smoking at a younger age, at least for girls.     

Artifacts of CD burning in the Microsoft Windows master file table

When theft of a physical item occurs it is detectable by the fact that the object is missing, however, when the theft of a digital item occurs it can go unnoticed as exact replicas can be created. The original file is left intact but valuable information has been absconded. One of the challenges facing digital forensic examiners is detecting when files have been copied off of a computer system in some fashion. While certain methods do leave residual evidence behind, CD Burning has long been held as a copying method that cannot be identified. Through testing of the burning process and close examination of the New Technology File System (NTFS), artifacts from the master file table in the various versions of Microsoft Windows, markers have been found that are associated with copying or "burning" files to CD or DVD. Potential evidence that was once overlooked may now be detectable.     

Safety in Intimate Partnerships: The Role of Appraisals and Threat

For most intimate partners, safety is an important goal and basic need. How a partner perceives safety has an impact on what happens in the relationship, and this will in turn affect the responses from the other partner. Lack of safety can provoke negative emotions and actions which can lead to relationship deterioration and violence. However, little is known about this process from the insider’s perspective. In this study, constructivist grounded theory methods were used to analyze interviews from individuals (n = 37) to better understand individual appraisals of relational safety. The results include a theory that illustrates the process of relational safety and threat. This model articulates how certain relational conditions precede a perception of safety or threat, which then leads to corresponding actions. Implications of the model include a focus on interaction and context when assessing for safety and abuse, as well as the importance of self regulation.     

Differential outcomes of court-supervised substance abuse treatment among California parolees and probationers

To explore the effectiveness of court-supervised drug treatment for California parolees, offender characteristics, treatment experiences, and outcomes were examined and contrasted to those of probationers. The analysis used statewide administrative data on 4,507 parolees and 22,701 probationers referred to treatment by Proposition 36 during fiscal year 2006-2007. Compared with probationers, parolee problems were more severe at treatment entry, more were treated in residential settings, treatment retention was shorter, and fewer completed treatment. Regarding outcomes, fewer parolees were successful at treatment discharge and more recidivated over 12-months post admission. Both groups improved in many areas by treatment discharge, but improvements were generally smaller among parolees. Significant interaction effects indicated that parolees benefited from residential care and more treatment days, even after controlling for covariates. Court-supervised drug treatment for parolees can "work;" however, parolees have more frequent and diverse needs, and their outcomes are enhanced by more intensive treatment. Findings suggest methods for optimizing the effectiveness of criminal-justice-supervised programs for treating drug-dependent offenders.     

Social anxiety as a predictor of dating aggression

By far, most research on the behavior of socially anxious individuals has focused on the "flight" rather than the "fight" response described in the traditional conceptualization of anxiety. More recently, however, there has been some speculation and emerging evidence suggesting that social anxiety and aggression may be related. The present study examined social anxiety as a predictor of dating aggression within a late adolescent sample. Two forms of dating aggression were assessed: physical aggression, such as slapping, use of a weapon, or forced sexual activity, and psychological aggression, such as slamming doors, insulting, or refusing to talk to one's partner. One aspect of social anxiety, Fear of Negative Evaluation (FNE), emerged as a significant predictor of male dating aggression, even after controlling for relationship quality. Notably, FNE was most predictive of increased aggression of both types when men also perceived their romantic relationship to be more antagonistic. Despite its demonstrated importance as a contextual variable, however, relationship quality did not mediate the association between FNE and psychological or physical aggression. Implications for prevailing conceptualizations of social anxiety and dating aggression are discussed.     

Kevin Kelly's Complexity Theory: The Politics and Ideology of Self-organising Systems

Regarded as a contemporary prophet of the new technology and economy, widely acclaimed author and editor of Wired , Kevin Kelly argues that the realms of nature and human construction are becoming one. Human-made things are becoming more lifelike and life is becoming more engineered. Utilising complexity theory and other concepts fashioned on the paradigmatic logic of biological systems, Kelly envisions a future with radically different forms of social and organisational control. In this future world, control is dispersed in highly pluralistic, open, and decentralised systems. Natural, technological, economic and social elements of the system co-evolve towards a superior, neo-biological civilisation that (among other things) will foster bottom-up control, co-ordinated change and co-operation among all elements. We contest Kelly's metaphysic of the new economy and new technology, arguing that he illicitly collapses technology and the economy into nature, using nature metaphors to legitimate the new forms of economy and organisation. We argue that Kelly fails to factor in the logic of capital into his scenario and does not explore the consequences of the new organisation of economy and new technology for the environment and society.     

Utility of the Frontonasal Suture for Estimating Age at Death in Human Skeletal Remains*

Abstract: This project evaluated the utility of the frontonasal suture for estimating age at death. Utilizing human remains of known age at death with varying degrees of fusion, curated at the American Museum of Natural History in New York City and the Smithsonian Institution’s National Museum of Natural History in Washington, DC, data were collected from the ectocranial surface of 522 crania; 68 of these were sagittally sectioned, allowing collection of internal data and observation of suture closure through the bone. Degree of ectocranial suture closure does not significantly predict age, even when sex and ancestry are accounted for. Suture closure progression data were converted into a Hershkovitz ratio (sum of the measurement of open portion divided by the total suture length), and regression models demonstrate that the effect of age accounts for only 13% of variation in suture closure.
