Introduction: Theatrical Trade Routes

An Introduction to the focus issue "Theatrical Traderoutes"

Satellite Broadcasting as Trade Routes in the Sky

The metaphor of trade routes - used from time to time to think about the distribution of ideas and imagery - ought to nourish our conception of transnational paths of delivery of electronic communications. Our minds are full of Rupert Murdoch and Disney, CNN and the BBC as traders in information, great shippers of data, distributors of sitcoms and news and advertisements. In the common reading of the world of electronic signals, the media is considered global, and the general impression is of a constant and ever-present net that can deposit information everywhere, disregarding boundaries. Our common and most recent experiences with the Internet seem, at first blush, to confirm and underscore a belief that data careers around the world from server to server, in patterns that seem virtually impervious to purposive planning or political and legal intervention (Volokh, 1995). Sender and receiver are linked in ways that appear indifferent to the route or mode by which they are connected. The obsolescence of boundaries is reinforced. So, too, has been the effect of the seamlessness of telephony in the developed world, obliterating distance and time. In telephony, transmission pathways seem invisible, or at least irrelevant, to the substantive decisions of most users. Although users are almost never conscious of it, all these modes of communication (postal service, telegrams and telephones) required the construction of international systems of regulation. Assurance of adherence to worldwide standards was a condition for their instantaneous nature and compatibility. The predominance of the West in terms of development and control of access to technology dictated the change in structure of international communication, putting pressure on non-Western members to Westernize, in order to comply with the prevailing system\u27s bureaucratic rules

The Origins of Ashkenaz, Ashkenazic Jews, and Yiddish

Recently, the geographical origins of Ashkenazic Jews (AJs) and their native language Yiddish were investigated by applying the Geographic Population Structure (GPS) to a cohort of exclusively Yiddish-speaking and multilingual AJs. GPS localized most AJs along major ancient trade routes in northeastern Turkey adjacent to primeval villages with names that resemble the word "Ashkenaz." These findings were compatible with the hypothesis of an Irano-Turko-Slavic origin for AJs and a Slavic origin for Yiddish and at odds with the Rhineland hypothesis advocating a Levantine origin for AJs and German origins for Yiddish. We discuss how these findings advance three ongoing debates concerning (1) the historical meaning of the term "Ashkenaz;" (2) the genetic structure of AJs and their geographical origins as inferred from multiple studies employing both modern and ancient DNA and original ancient DNA analyses; and (3) the development of Yiddish. We provide additional validation to the non-Levantine origin of AJs using ancient DNA from the Near East and the Levant. Due to the rising popularity of geo-localization tools to address questions of origin, we briefly discuss the advantages and limitations of popular tools with focus on the GPS approach. Our results reinforce the non-Levantine origins of AJs

Cryptic Eimeria genotypes are common across the southern but not northern hemisphere

The phylum Apicomplexa includes parasites of medical, zoonotic and veterinary significance. Understanding the global distribution and genetic diversity of these protozoa is of fundamental importance for efficient, robust and long-lasting methods of control. Eimeria spp. cause intestinal coccidiosis in all major livestock animals and are the most important parasites of domestic chickens in terms of both economic impact and animal welfare. Despite having significant negative impacts on the efficiency of food production, many fundamental questions relating to the global distribution and genetic variation of Eimeria spp. remain largely unanswered. Here, we provide the broadest map yet of Eimeria occurrence for domestic chickens, confirming that all the known species (Eimeria acervulina, Eimeria brunetti, Eimeria maxima, Eimeria mitis, Eimeria necatrix, Eimeria praecox, Eimeria tenella) are present in all six continents where chickens are found (including 21 countries). Analysis of 248 internal transcribed spacer sequences derived from 17 countries provided evidence of possible allopatric diversity for species such as E. tenella (FST values ⩽0.34) but not E. acervulina and E. mitis, and highlighted a trend towards widespread genetic variance. We found that three genetic variants described previously only in Australia and southern Africa (operational taxonomic units x, y and z) have a wide distribution across the southern, but not the northern hemisphere. While the drivers for such a polarised distribution of these operational taxonomic unit genotypes remains unclear, the occurrence of genetically variant Eimeria may pose a risk to food security and animal welfare in Europe and North America should these parasites spread to the northern hemisphere
