Sex assessment with the radius in Portuguese skeletal populations (late 19th - early to mid 20th centuries).
TL;DR: Measurements of the radius are useful to develop standard guidelines for sex estimation of anonymous skeletal remains and show an accuracy ranging from 77.7% to 89.8% (cross-validation), and from 70% to 86% (test sample) in univariable and multivariable models.

TL;DR: South Africa has one of the highest crime rates in the world and the discovery of dismembered bodies for human identification process poses a greater challenge as discussed by the authors, and the South African Africans (also kno...

Recent advances in sex identification of human skeletal remains in South Africa : review article
TL;DR: In this paper, a literature review was carried out wherein the available methods of sex identification (morphological, metrical, geometric morphometrics and molecular) from South African skeletal material were critically examined.

Accuracies of discriminant function equations for sex estimation using long bones of upper extremities.
TL;DR: Assessment of the accuracies of population-specific discriminant function equations derived from measurements of long bones of the upper limb of South African population groups confirms that population- specific equations should not be applied to other population groups.

Adjusted binary classification (ABC) model in forensic science: An example on sex classification from handprint dimensions.
TL;DR: This paper proposed adjusted binary classification (ABC) algorithm that automatically adjusts posterior probabilities to reach classification accuracy and positive/negative predicted values (PPV, NPV) of 95 %, while PPVs/NPVs ranged between 78.2 and 93 %.

TL;DR: A detailed genetic analysis of most major groups of African populations is provided, suggesting that Africans represent 14 ancestral populations that correlate with self-described ethnicity and shared cultural and/or linguistic properties.

Sexual dimorphism in human lower limb bone structure: relationship to subsistence strategy and sexual division of labor
TL;DR: Upper and Middle Paleolithic samples are indistinguishable in terms of sexual dimorphism from modern huntergatherers, suggesting a similar sexual division of labor.

Sex determination from the femur and tibia in South African whites

TL;DR: In this article, the authors used SPSS discriminant function analysis to determine the sex of 56 male and 50 female individuals from cadaver collections, and found that the distal breadths from both the femur and tibia provided the best discrimination.

Sex determination and estimation of stature from the long bones of the arm
TL;DR: The present study was restricted to few easily accessible dimensions from bones which were prepared only by mechanically removing soft tissues, tendons and ligaments, leading to unsatifactory results with large 95%-confidence intervals for the coefficients and high standard errors of estimate.
