Intrataxonomic variability in metapodial and femur bone density related to age in guanaco (Lama guanicoe). Zooarchaeological and taphonomical implications

The aim of this paper is to present new information about bone mineral density (BMD) variability in guanaco (Lama guanicoe), a South American wild camelid; while taking into account its ontogenic development. The importance of considering intrataxonomic variability in bone density related to age for constructing zooarchaeological indices and applying them to archaeological assemblages is also discussed. The results presented here were developed from a large sample of 46 metacarpals and 45 femurs of modern guanacos, ranging in age from ca. 6 months of gestation to 12 years. Bone structural densities were measured using a biphotonic X-ray densitometer, DEXA method, Norland EXCELL and the bone mineral content (BMC) of each scanned portion or complete element was divided by its volume, which was obtained independently by water displacement. Our results indicate that the bone density of each anatomical unit is highly variable, even among individuals of the same species. According to metacarpals data, age is an important factor affecting BMD. Moreover, our study shows that the density ranges of different skeletal elements can overlap, suggesting that it is not possible to predict that a certain element is always denser than another one. Finally, we present new evidence about the potential age-related taphonomic bias in faunal assemblages, indicating that meanwhile some skeletal elements show clear differences in their density between their fused and unfused state (metacarpal) other do not (femur).     

Loyal citizens or dangerous stateless refugees? The ‘Armenian Question’ in World War II Romania, 1940–44

After the massacres and genocide perpetrated by the Ottoman Empire, thousands of Armenian refugees arrived in Romania and reinvigorated the local minority group (native Armenians), which at that time was mostly assimilated. While native Armenians were citizens, the refugees were stateless people holding Nansen passports. From the 1930s on, and especially during the Antonescu regime (1940–44), the legal status of Armenians, especially of Nansen refugees, worsened due to the rise of ethno-nationalism, particularly in the economic area (a process called Romanianization). This article investigates the ‘Armenian Question’ in World War II Romania, including its connection with the ‘Jewish Question’. Believing that Nansen Armenians were disloyal to Romania—because some of them wanted to repatriate to Soviet Armenia and engaged in communist and fascist revolutionary organizations—and profited from the Romanian economy, and especially from Romanianization, the Antonescu regime treated this group as dangerous foreigners and subjected them to police surveillance and legal and economic persecution, resembling, to a certain extent, its antisemitic policy. However, Antonescu did not push the persecution of Nansen Armenians too far and, in general, they fared better than the Jews.     

Hacking the citizenry?: Personality profiling, ‘big data’ and the election of Donald Trump

This article examines the reported use of ‘big data’ analysis by Cambridge Analytica in support of Donald Trump's presidential campaign. It investigates the transformations enveloping the overlapping worlds of politics, technology and social science. In particular, it critically reviews new developments in the field of psychometrics that have enabled researchers to harvest vast quantities of data by accessing social media platforms such as Facebook. The article also assesses claims that predictive analytics and ‘psychographics’ led to Trump's unexpected victory. The article concludes with a broader discussion about the state of political discourse in an era of digital communication.
