The paradoxical meanings of the artifact owls (Athene noctua) at the University of South Africa: An impediment to transformation,decolonization, and Africanization discourse

This paper interprets the expressions embedded in the artifact Owls displayed at the Theo Van Wijk building of the University of South Africa (Unisa) in relation to the university's transformation, decolonization, and Africanization discourse. These artifacts are said to depict Unisa as a space of wisdom; this in terms of Greek mythology and philosophy. The use of Greek mythology and philosophy in a university meant to be promoting African values, systems, and beliefs contradicts the university's transformation, decolonization, and Africanization discourse. Philosophical inquiry was adopted to intellectually interpret what these artifact Owls expressed. The paper found that these Owls are a point of contestation and conflict between Western and African cultures. The perpetual display of these Owls upholds and sustains tendencies of colonialism and apartheid although discarding Africannes. Unisa is reduced into a Western‐centric space of little and irrelevant significance for the postapartheid democratic state. These artifact Owls must be removed and replaced by an African‐friendly symbolism of wisdom. Sankambe could be the best option.     

Skeletal indicators of pregnancy and parturition: a historical review

Over a century of scientific literature has documented the research and analysis relating to the possible skeletal evidence of pregnancy, parturition, and childcare, yet today, there still exists variation in methodology and interpretation. Historical perspective facilitates understanding of the growth and development of the theories and research currently available to the forensic science community. Review of the relevant literature clearly indicates that specific skeletal alterations are not exclusively connected to obstetrical events. Although parturition and related events have been shown to leave various alterations on bone, the research record also demonstrates that other factors can contribute to the same or similar changes. Additionally, such alterations can often be found in nulliparous women and men and are frequently absent in parous and multiparous women. This literature review calls for the continued exploration of skeletal alterations for determining parity status in human skeletal remains.     

Revisiting Licensed Handgun Carrying: Personal Protection or Interpersonal Liability?

No debate is more sensitive or polemical than the question of ??gun rights?? in the U.S., and licensing private citizens to carry concealed handguns is the most controversial ??right?? of all. The morally charged nature of this controversy is reflected in the disparate results reported by various researchers who analyze the effects of these laws, and also by the especially intense methodological scrutiny that follows published research. A National Science Academy review of existing gun policy research issues methodological recommendations which may help resolve scientifically the question of whether or how ??right to carry?? licensing effects rates of lethal firearm violence. Similar efforts have been published previously, but this study improves upon those earlier efforts by increasing the sample cross-section, by further refining the model specification, and by distinguishing conceptually ??shall issue?? RTC laws from ??may issue?? RTC laws. The results provisionally suggest that the former increases homicide rates whereas the latter decreases them.     

Virtual forensic entomology: improving estimates of minimum post-mortem interval with 3D micro-computed tomography

We demonstrate how micro-computed tomography (micro-CT) can be a powerful tool for describing internal and external morphological changes in Calliphora vicina (Diptera: Calliphoridae) during metamorphosis. Pupae were sampled during the 1st, 2nd, 3rd and 4th quarter of development after the onset of pupariation at 23 °C, and placed directly into 80% ethanol for preservation. In order to find the optimal contrast, four batches of pupae were treated differently: batch one was stained in 0.5M aqueous iodine for 1 day; two for 7 days; three was tagged with a radiopaque dye; four was left unstained (control). Pupae stained for 7d in iodine resulted in the best contrast micro-CT scans. The scans were of sufficiently high spatial resolution (17.2 μm) to visualise the internal morphology of developing pharate adults at all four ages. A combination of external and internal morphological characters was shown to have the potential to estimate the age of blowfly pupae with a higher degree of accuracy and precision than using external morphological characters alone. Age specific developmental characters are described. The technique could be used as a measure to estimate a minimum post-mortem interval in cases of suspicious death where pupae are the oldest stages of insect evidence collected.

Prediction of Police Officer Performance Among New Mexico State Police as Assessed by the Personality Assessment Inventory

Little research has been conducted regarding the use of the Personality Assessment Inventory (PAI) in law enforcement screening and selection. The limited body of research that does exist appears to support its utility in the selection process. The purpose of the present study was to investigate the validity and reliability of the Psychological Rating Risk Factor Statement (PRRFS) developed by Roberts, Thompson, and Johnson (2004) in predicting and discriminating problem from non-problem New Mexico State Police (NMSP) applicants. PAI profiles for each officer were obtained and transferred into the PAI Law Enforcement, Corrections, and Public Safety Selection software program, which generated probability estimates (PRRFS) to predict the likelihood that participants were not well-suited for a career in law enforcement. Subsequent logistic regression and receiver operating characteristic (ROC) statistical analyses revealed that the PRRFS was ineffective in predicting and discriminating between problem and non-problem officers. Potential explanations for this finding are discussed.     

Recovery Rates of Human Fetal Skeletal Remains Using Varying Mesh Sizes

Human fetal skeletal elements of different gestational ages were screened with multiple mesh sizes (6.4 mm [1/4 inch], 3.2 mm [1/8 inch], 2.0 mm, and 1.0 mm) to determine their recovery rates. All remains were previously macerated, and no significantly damaged elements were used. The 6.4 mm mesh allowed a large loss of elements (63.2% overall), including diagnostic elements, while no diagnostic elements were lost when the 1 mm mesh (0.2%) was used. When using the 3.2 mm mesh, 16.2% of the bones were lost, including some diagnostic elements (primarily tooth crowns), while 7.5% were lost using the 2.0 mm mesh. The authors recommend that the potential loss of information incurred when utilizing larger mesh sizes be taken into consideration when planning recovery methods where fetal remains may be encountered and that a minimum of 1.0 mm mesh be utilized in recovery contexts known to include fetal remains.
