The preservation of ectoparasites in archaeological sites is normally problematic, but the dry environment of the Egyptian desert keeps even the very fragile remains of fleas intact.Fleas, Siphonaptera, can be divided in three large groups: the sedentary fleas that live in the nest of their hosts, the mobile fleas that still require a nest but can also live on the host, and the stick-tight fleas that attach themselves on the host. The human flea, Pulex irritans L. is one of the mobile fleas, nowadays cosmopolitan, and has been found on a wide range of hosts (Hopla 1980; Cooper 2001). Man evolved in the Old World and although the human flea is closely associated with him, it probably has a New World origin (Hopla 1980: 201; Traub 1985: 408; Buckland & Sadler 1989), as all its congeners are found in the Americas. Donkin (1985) thought that the original host for P. irritans was the peccary (family Tayassuidae). However peccaries do not have relatively permanent nest sites, and Buckland & Sadler (19891, after examining the profiles of different animal hosts, have suggested Cavia porcellus L., the guinea pig (cavy) as the primary host for the flea. C. porcellus was domesticated during the pre-Colombian period for its meat, but its contribution to the South American agricultural economy has always been on a local scale. Recent archaeological finds of Pulex sp. on a pre-Columbian C. porcellus from Peru (Dittmar 2000) support the above hypothesis.

Bats provide important ecosystem services as pollinators, seed dispersers, and/or insect controllers, but they have also been found harboring different viruses with zoonotic potential. Virome studies in bats distributed in Asia, Africa, Europe, and North America have increased dramatically over the past decade, whereas information on viruses infecting South American species is scarce. We explored the virome of Tadarida brasiliensis, an insectivorous New World bat species inhabiting a maternity colony in Rosario (Argentina), by a metagenomic approach. The analysis of five pooled oral/anal swab samples indicated the presence of 43 different taxonomic viral families infecting a wide range of hosts. By conventional nucleic acid detection techniques and/or bioinformatics approaches, the genomes of two novel viruses were completely covered clustering into the Papillomaviridae (Tadarida brasiliensis papillomavirus type 1, TbraPV1) and Genomoviridae (Tadarida brasiliensis gemykibivirus 1, TbGkyV1) families. TbraPV1 is the first papillomavirus type identified in this host and the prototype of a novel genus. TbGkyV1 is the first genomovirus reported in New World bats and constitutes a new species within the genus Gemykibivirus. Our findings extend the knowledge about oral/anal viromes of a South American bat species and contribute to understand the evolution and genetic diversity of the novel characterized viruses.

AbstractHaving identified previously (Bonta 2015) the Peircean Category Firstness as the semiotic basis (or cultural Prime Symbol) for Australian Aboriginal culture, this paper examines the “lens” of Firstness as it is manifest in a variety of aboriginal (or “Shamanic”) cultures worldwide. By studying the semiotic contours of religion, language, social organization, and art, we find systemic prioritization of Firstness in its various manifestations, across a wide range of aboriginal cultures from Australia to the Indian Subcontinent to aboriginal Siberia and the New World. Shamanic culture, despite its ethnic and geographic variety, may therefore be represented as a semiotic type – and, in addition, one that, in its pristine form, is nearly extinct.

This Element examines urban imaginaries during the expansion of international news between the late nineteenth and the early twentieth centuries, when everyday information about faraway places found its way into newspapers all over the world. Building on the premise that news carried an unprecedented power to shape representations of the world, it follows this development as it made its way to regular readers beyond the dominant information poles, in the great port-cities of the South American Atlantic. Based on five case studies of typical turn-of-the-century foreign news, Lila Caimari shows how current events opened windows onto distant cities, feeding a new world horizon that was at once wider and eminently urban.

We discuss the radiocarbon chronology of Late Pleistocene archaeology in the Japanese islands. In sum, 429 samples from more than 100 archaeological sites were compiled and then divided into three periods and four stages. The Early Upper Paleolithic, characterized by Trapezoid industries, lasted during approximately 34-26 ka. The Late Upper Paleolithic period includes both the backed-blade stage and point-tool stage, the latter appearing chronologically later than the former. This stage covers ~25–15 ka. The Final Upper Paleolithic and Incipient Jomon are distinguished by the appearance of microblade industries and the emergence of pottery at the end of this period. This period covers approximately 14-12 ka. The microblade tradition, in the broadest sense, is strongly connected to the background of peopling of the New World. New data on the transitional stage from the Middle to the Upper Paleolithic are also discussed in regards to three archaeological sites. Issues on the application of the 14C calibration to the whole Japanese Upper Paleolithic are critically evaluated.

Workplace Assessment

Almost 20 years after McKinsey introduced the idea of a war for talent, technology is disrupting the talent identification industry. From smartphone profiling apps to workplace big data, the digital revolution has produced a wide range of new tools for making quick and cheap inferences about human potential and predicting future work performance. However, academic industrial–organizational (I-O) psychologists appear to be mostly spectators. Indeed, there is little scientific research on innovative assessment methods, leaving human resources (HR) practitioners with no credible evidence to evaluate the utility of such tools. To this end, this article provides an overview of new talent identification tools, using traditional workplace assessment methods as the organizing framework for classifying and evaluating new tools, which are largely technologically enhanced versions of traditional methods. We highlight some opportunities and challenges for I-O psychology practitioners interested in exploring and improving these innovations.

Abstract There is relatively good evidence that non-human primates can communicate about objects and events in their environment in ways that allow recipients to draw inferences about the nature of the event experienced by the signaller. In some species, there is also evidence that the basic semantic units are not individual calls, but call sequences and the combinations generated by them. These two findings are relevant to theories pertaining to the origins of human language because of the resemblances of these phenomena with linguistic reference and syntactic organisation. Until recently, however, most research efforts on the primate origins of human language have involved Old World species with comparatively few systematic studies on New World monkeys, which has prevented insights into the deeper phylogenetic roots and evolutionary origins of language-relevant capacities. To address this, we review the older primate literature and very recent evidence for functionally referential communication and call combinations in New World primates. Within the existing literature there is ample evidence in both Callitrichids and Ce-bids for acoustically distinct call variants given to external disturbances that are accompanied by distinct behavioural responses. A general pattern is that one call type is typically produced in response to a wide range of general disturbances, often on the ground but also including inter-group encounters, while another call type is produced in response to a much narrower range of aerial threats. This pattern is already described for Old World monkeys and Prosimians, suggesting an early evolutionary origin. Second, recent work with black-fronted titi monkeys has produced evidence for different alarm call sequences consisting of acoustically distinct call types. These sequences appear to encode several aspects of the predation event simultaneously, notably predator type and location. Since meaningful call sequences have already been described in Old World primates, we suggest that basic combinatorial vocal communication has evolved in the primate lineage long before the advent of language. Moreover, it is possible that some of these communicative abilities have evolved even earlier, or independently, as there is comparable evidence in other taxonomic groups. We discuss these findings in an attempt to shed further light on the primate stock from which human language has arisen.

Purpose. The article describes the history and analysis of the main issues in the study of archaeological sites of the Saka period in Semirechye. They are presented by three main types on this territory: burial and memorial complexes, settlements and hoards. The first type of monuments includes numerous burial mounds, where the elite burials of “royal” type and ordinary burials are located. Both social groups are combined by the unity of funeral rites, and the main differences are the complexity of architecture, memorial practices, and richness of burial equipment in the “royal” type burial mounds. The second category of monuments is presented by the settlements that are mostly small in size. The constructions like half dugouts were discovered on them, which gave a rich ceramic material. The third type of monuments of the Saka period in Semirechye includes numerous hoards of bronze items. Some of them are represented by the cult objects (sacrificial tables, lamps and cauldrons) that mark the places of worship. A significant percentage of the hoards contain items of weapons, horse equipment and household purposes and, apparently, serve as offerings to the spirits. However, despite the considerable progress in the study of the Saka monuments of the Semirechye Region, the main problem is their cultural attribution at this time. Some researchers suggest that the independent Saka archaeological culture was formed and developed on the territory of Semirechye in the Early Iron Age, while others believe that the Saka monuments of this region belong to the broader historical and cultural community that also covers the neighboring regions of Kyrgyzstan and Xinjiang. Results Another important issue in the study of the Saka sites of Semirechye is to clarify the chronology of burial and memorial complexes. Up to now, the significant database of radiocarbon dates has been accumulated, which allows us to consider the chronological positions of a wide range of monuments in a new way. It was of great importance to obtain such dates from several burials of Karatuma necropolis, which showed that it belonged to the Saka period, since burial monuments of this appearance are traditionally dated back to the Wusun period. Conclusion. The necessity of solution of these problems is an urgent task for further research of burial and settlement objects of the Saka period in this region.

El actual sistema energético mundial se caracteriza por una alta dependencia de los combustibles fósiles, un paradigma que empieza a encontrar dificultades en tanto se agotan las reservas existentes y aumentan los costos ecológicos. Así, la incorporación de energías renovables, su generación en forma distribuida y el crecimiento del parque automotor eléctrico, se presentan como la triada más prometedora en la conformación de un nuevo paradigma más eficiente y sustentable. Este artículo se centra en la importancia que adquieren los acumuladores energéticos ante este panorama, principalmente por su rol en la estabilización de las redes y posibilitar el autoconsumo y la propulsión eléctrica. Identifica en las baterías de ion-litio un abanico de posibilidades para Sudamérica, que posee las reservas más importantes de litio en el mundo, incorporando la idea del desarrollo dentro del nuevo patrón energético y en un mercado actual y potencial de grandes dimensiones. Abstract The current global energy system is characterized by a high dependence on fossil fuels, a paradigm that begins to encounter difficulties as existing reserves are depleted and ecological costs increase. Thus, the incorporation of renewable energies, their generation in a distributed form and the growth of the electric motor park, are presented as the most promising triad in the conformation of a new, more efficient and sustainable paradigm. This article focuses on the importance that energy accumulators acquire in this scenario, mainly due to their role in stabilizing networks and enabling self-consumption and electric propulsion. It identifies lithium-ion batteries with a wide range of possibilities for South America, which has the most important reserves of lithium in the world, incorporating the idea of ​​development within the new energy pattern and in a current and potential market of large dimensions.

AbstractThe Old World cotton bollworm Helicoverpa armigera was first detected in Brazil with subsequent reports from Paraguay, Argentina, Bolivia, and Uruguay. This pattern suggests that the H. armigera spread across the South American continent following incursions into northern/central Brazil, however, this hypothesis has not been tested. Here we compare northern and central Brazilian H. armigera mtDNA COI haplotypes with those from southern Brazil, Uruguay, Argentina, and Paraguay. We infer spatial genetic and gene flow patterns of this dispersive pest in the agricultural landscape of South America. We show that the spatial distribution of H. armigera mtDNA haplotypes and its inferred gene flow patterns in the southwestern region of South America exhibited signatures inconsistent with a single incursion hypothesis. Simulations on spatial distribution patterns show that the detection of rare and/or the absence of dominant mtDNA haplotypes in southern H. armigera populations are inconsistent with genetic signatures observed in northern and central Brazil. Incursions of H. armigera into the New World are therefore likely to have involved independent events in northern/central Brazil, and southern Brazil/Uruguay-Argentina-Paraguay. This study demonstrates the significant biosecurity challenges facing the South American continent, and highlights alternate pathways for introductions of alien species into the New World.
