Virtual anthropology: a preliminary test of macroscopic observation versus 3D surface scans and computed tomography (CT) scans

Virtual anthropology (VA) is based on applying anthropological methods currently used to analyse bones to 3D models of human remains. While great advances have been made in this endeavour in the past decade, several interrogations concerning how reliable these models are and what their proper use should be remain unanswered. In this research, a fundamental assumption of VA has been investigated: if the way we perceive and apply an anthropological method is truly similar when looking at bones macroscopically and through various 3D media. In order to answer, 10 skulls of known age and sex were scanned using a computed tomography (CT) scanner and a 3D surface scanner. Two observers separately applied a defined staging method to eight suture sites on these skulls, first looking at the bone macroscopically, then at the 3D surface scan, and finally on the CT scan. Two rounds of observation were carried out by each observer. Intra- and inter-observer error were evaluated, and two sample t-tests used to evaluate if the different types of medium used yielded significantly different observations. The results show a high degree of inter-observer error, and that data obtained from 3D surface scans differ from macroscopic observation (confidence level 95%, P ≤ 0.05). CT scans, in these settings, yielded results comparable to those obtained through macroscopic observations. These results offer many possibilities for future research, including indications on the kind of anthropological methods and anatomical landmarks that might be reliably transferable to the virtual environment. All current methods used in traditional anthropology should be tested, and if they prove unreliable, new techniques to analyse bones from virtual models should be developed.

Key points

• Large discrepancies between observation on dry bones and computer-generated 3D models (surface scans or CT scans) could lead to the re-evaluation of the suitability of traditional anthropological methods for application on 3D models.
• This preliminary study evaluates whether macroscopic, 3D surface scans, and CT scans viewings generate different observations.
• The results indicate that the data are not always coherent across all three media of observation.
• Explanations include the aspect given to the bone by the 3D software, differences between handling bones in real life versus on a computer, and level of expertise of the observers.

     

Selenium determination in mother and child's hair by electrothermal atomic absorption spectrometry

A method for the selenium determination in a mother and her child's hair using palladium as a chemical modifier was optimized. The sample was digested with nitric acid and hydrogen peroxide and diluted to 5 ml. To achieve complete mineralization the samples were ashed at 1200 degrees C in the presence of palladium as a chemical modifier. The optimum atomization temperature was 1900 degrees C. The precision and accuracy of the method were studied using the reference material CRM 397. Results of calibration using aqueous standards and the standard addition method were compared. The method was applied to the selenium determination in 30 samples of the mother's and child's hair. The levels found were 0.54 +/- 0.34 microgram/g for mother's hair and 0.77 +/- 0.25 microgram/g for child's hair.     

Long persistence of rigor mortis at constant low temperature

We studied the persistence of rigor mortis by using physical manipulation. We tested the mobility of the knee on 146 corpses kept under refrigeration at Torino's city mortuary at a constant temperature of +4 degrees C. We found a persistence of complete rigor lasting for 10 days in all the cadavers we kept under observation; and in one case, rigor lasted for 16 days. Between the 11th and the 17th days, a progressively increasing number of corpses showed a change from complete into partial rigor (characterized by partial bending of the articulation). After the 17th day, all the remaining corpses showed partial rigor and in the two cadavers that were kept under observation "à outrance" we found the absolute resolution of rigor mortis occurred on the 28th day. Our results prove that it is possible to find a persistence of rigor mortis that is much longer than the expected when environmental conditions resemble average outdoor winter temperatures in temperate zones. Therefore, this datum must be considered when a corpse is found in those environmental conditions so that when estimating the time of death, we are not misled by the long persistence of rigor mortis.     

Community rehabilitation workers as catalysts for disability: inclusive youth development through service learning

This paper explores access to health and education for disabled youth in sites with and without community rehabilitation workers (CRWs). A cross-sectional survey using a structured questionnaire was undertaken in nine sites in South Africa, and a snowball sample of 523 disabled youths of both sexes, aged between 18 and 35 years, was selected. The survey found that a significantly larger proportion of disabled youth living in sites with CRWs were seen by health care workers at home, and that there was a large difference in educational access between sites with and without CRWs. CRWs are well positioned to promote equal citizenship for disabled youth through service learning with occupational therapy final year students to improve access to health and education, so that barriers to their participation in economic development are removed.     

Beyond left and right: the eclectic populism of the Five Star Movement

Abstract

Born in 2009, the Five Star Movement (FSM) has been one of the most electorally successful European populist parties since 2013. While its classification as a populist party is unanimously accepted, some have considered it close to left-libertarian positions, others as an anti-immigrant far right party, and still others have simply deemed it as unclassifiable. This article sets out to shed light on this question, using the official documents issued by the party since 2009, posts retrieved from Grillo’s blog during three electoral campaigns, and the opinions of the party’s supporters as expressed in three surveys in 2013, 2014 and 2016. Although displaying a clear anti-establishment identity, in economic terms it presents left-of-centre positions inconsistently mixed with more conservative proposals, while on the issues of citizenship and immigration, it has an elusive positioning, mixing national securitisation and international humanitarianism. The conclusions highlight the eclectic nature of FSM’s populism.     

Ian Turner’s The Australian Dream and Australia’s “settler transition”

Focusing on radical labour historian Ian Turner’s The Australian Dream (1968), this article reflects on the evolution of Australia’s settler colonial imagination. During a few crucial decades in the nineteenth century, colonial traditions were overcome by settler colonial ones. The former espoused a system where British rulers would paternally manage a colonial environment and all its populations (pastoralists, free settlers, convicts, emancipated convicts, and Indigenous peoples); the latter advocated the establishment of self-reliant agricultural communities of free settlers. In Replenishing the Earth (2009), James Belich distinguished between settler “transition” and settler “revolution”, and emphasised the imaginative elements that underpin and precede the shift to settler self-government. As the global settler transition took hold, locales usually associated with the perception and expectation of degenerative processes were reconfigured as propitious sites for experimenting in sociopolitical regeneration. Following and expanding on Belich’s framework, this article links Australia’s settler transition with its historiography.
