Great-tailed grackles (Quiscalus mexicanus) have dramatically expanded into North America over the past century. However, little is known about the blood that parasites they support. Here, for the first time, we document an assemblage of trypanosome, haemosporida, and filarial nematodes co-circulating in invasive great-tailed grackles. Between February and July, 2015, 61 individuals were captured in an urban environment of College Station, Texas. Field microscopy and molecular diagnostics indicate that 52% (24/46) were visually infected with filarioid nematodes, 24% (11/46) with avian trypanosomes, and 73% (n = 44/60) with haemosporida parasites, such as Haemoproteus (Parahaemoproteus) and Plasmodium cathemerium. Overall, 87% of great-tailed grackles were infected with blood parasites. Although 50% of individuals hosted parasites from multiple phylum, no patterns of parasite assembly were observed. Results indicate that great-tailed grackles can support a relatively high level of blood parasitism. However, the consequences for avian health remain to be determined.

The purpose of the article is a realization of tradiтionalism as mеtаdirection of art in XX century that historically comparable with mеtаdirection of styles modern-vanguard, jointly forming artistic paradigm of the past century, then the last becomes firmly established in nеоrеnaissаnce world-outlook according to with "system of Leonardo da Vinci" P. Valéry. The methodology of the study is a historian-cомpаrаtive approach, as this demonstrates works of A.Losev, also culturology foreshortening of musicology analysis, as this is given in "Symphonic etude" and others beside B.Asafiev. The scientific novelty of the work is conditioned, first, that that for the first time in specified foreshortening is presented analysis composition of V.Vlasov, but, secondly, original is a theoretical idea about cultural intrusion in style-typology life length Neo-Gothic that impossible was in classicist of music creative activity to XIX-XX cent. Conclusions. Traditionalism forms mеtаdirection since in base this style unity prescribed expressiveness of romanticism-pоstromanticism and realism XIX century that forms analogies to mеtаstyle forming of the modernism (vеrism at the end XIX - at the beginning initially XX century, "hard" type of the neoclassicism I. Stravinsky and P. Hindemith, others), in which vanguard took place as focus of the symbiosis of the styles-directions expressionism, futurism, primitivism, having formed new unity of the vanguard of the second wave in the manner of nеоexpressionism.

Koch (1844) originally described only the male of Haemaphysalis (Rhipistoma) elliptica (Koch, 1844), which he named Rhipistoma ellipticum. For the past century, however, this name has been considered a junior synonym of Haemaphysalis (Rhipistoma) leachi (Audouin, 1826), or a nomen nudum. We redescribe here the male and larva of H. (R.) elliptica and describe the female and nymph for the first time. Our redescription is based on the male holotype, plus numerous specimens from southern and East Africa. The adults of this tick parasitize domestic and wild carnivores, and the immature stages infest rodents in these regions. For comparative purposes redescriptions of all parasitic stages of H. (R.) leachi are provided. It parasitizes the same hosts as H. (R.) elliptica in Egypt, and in northeastern, Central, West and East Africa.

AbstractS 786 is one of the so-called Orthodoxorum charters, a group of documents which provide important evidence about the Anglo-Saxon chancery, the development of charters in the tenth century, and the history of Pershore Abbey and the tenth-century Benedictine reforms. The document has therefore received a great deal of attention over the past century or so, but this attention has been focussed on the surviving tenth-century single sheet, and so a second, significantly different version of the text has lain unnoticed. This second version is preserved in a copy made by John Joscelyn, Latin Secretary to Archbishop Matthew Parker. Among the material uniquely preserved in this copy are Old English charter bounds for Wyegate (GL), Cumbtune (Compton, GL?) and part of the bounds probably for Lydney (GL), as well as a reference to a grant by Bishop Werferth of Worcester. In this article both versions of the document are discussed and are published together for the first time, and a translation of the single sheet is provided. The history of the two versions is discussed in some detail, and the text of a twelfth-century letter which refers to the charter is also edited and translated.

The article makes an attempt to analyse scope and timing prospects of students’ life goals in two East-Central European countries – Poland and Ukraine. These two countries were under similar socio-economic circumstances in the last decade of the past century, but nowadays the situation is totally different. The study was conducted in November and December 2019 using the authors’ survey questionnaire carried out on the sample of 658 university students from Lublin and Kyiv. Our research showed that symmetry in students’ life goals primarily occurred in the scope of goals and values, with a greater focus on family in the case of Ukrainian students and on material goods and business activity for Polish students. Asymmetry was observed in the term of planned implementation of particular life goals: Ukrainian students expected stabilisation based on family, children, and apartment ownership within 5 years from graduation and Polish students expected such stabilisation within 10 years after graduation. Moreover, more optimistic expectations for the future were observed in the case of Ukrainian students.

Over the past several decades, many attempts have been made to trace the route of the Hernando de Soto expedition through Texas. All of these efforts have been based on an incomplete understanding of the archeological record relating to the 16th century in Texas. A number of archeological investigations have been conducted over the past several decades, and provide better knowledge of the late prehistoric period in Texas. This article examines the route of the de Soto expedition, under the command of Luis de Moscoso, through the state based on our present archeological knowledge. The expedition is proposed to have entered Texas along the Red River and traveled southward until reaching Caddoan settlements near Nacogdoches in the east-central portion of the state. From here the expedition traveled westward until reaching the Guadalupe River of south-central Texas, where the soldiers abandoned hopes of reaching New Spain by an overland route. Implications of the proposed route upon Native American populations of eastern Texas are discussed and related to the possible introduction of European diseases.

Contemporary identity in Thailand is prominently configured through an allegiance of reformed Buddhism with the modern Thai state. What is not well understood, however, is the centrality of “comparative religion” to the construction of this naturalized religionationalist identity, for interreligious study in Siam has been an integral component of modern Thai identity since the mid-nineteenth century. First, the emergence of “religion” as an object of study in modern Thailand is explored here, in an effort to detail the genealogy of this field for the first time. The articulation of Thai religious identity is identified as a response to intellectual challenges from colonial influences, especially the reproofs of Buddhism by Christian missionaries and Orientalist scholarship on religion. Thai Buddhist intellectuals responded to these challenges by robustly countering that Theravada Buddhism was, in fact, superior to Christianity and other religions. Finally, I explore the contentions between the Thai Buddhist apologetics and their opponents as a genealogy of the knowledge in comparative religion in Siam over the past century and a half. Given this genealogy, the field of comparative religion in Thailand is revealed as being far from a disinterested pursuit of knowledge; rather, it is part of the formation and reaffirmation of Thai national identity.


The T. S. Eliot Studies Annual brings together a collection of essays at the fore of the critical reassessment of Eliot’s life and work in light of the ongoing publication of his letters, critical volumes of his complete prose, the new edition of his complete poems, and the forthcoming critical edition of his plays. The volume features various approaches, but the dominant methodology is a historicist: essays reconsider Eliot’s work as a poet, critic, playwright, editor, and foremost exemplar of literary modernism in light of contemporary debate, contexts, and newly available primary materials. In addition to cutting-edge scholarship re-dating the chronology and genesis of Eliot’s poetry and plays, recasting longstanding scholarly debates, and reframing standard critical narratives, this volume contains two special forums. The first commemorates the centenary of the publication of “The Love Song of J. Alfred Prufrock.” Together, essays in this cluster reexamine the circumstances surrounding the poem’s original publication, recontextualize its allusions, and reconstruct its reception over the past century. The second essay cluster examines the annotations made in books from Eliot’s personal library, recently made available to researchers for the first time. The book concludes with a bibliography of recent Eliot scholarship, including book reviews, dissertations, journal articles, book chapters, and monograph publications.

For the first time available in English, Licia do Prado Valladares’s classic anthropological study of Brazil’s vast, densely populated urban living environments reveals how the idea of the favela became an internationally established—and even attractive and exotic—representation of poverty. The study traces how the term “favela” emerged as an analytic category beginning in the mid-1960s, showing how it became the object of immense popular debate and sustained social science research. But the concept of the favela so favored by social scientists is not, Valladares argues, a straightforward reflection of its social reality, and it often obscures more than it reveals. The established representation of favelas undercuts more complex, accurate, and historicized explanations of Brazilian development. It marks and perpetuates favelas as zones of exception rather than as integral to Brazil’s modernization over the past century. And it has had important repercussions for the direction of research and policy affecting the lives of millions of Brazilians. Valladares’s foundational book will be welcomed by all who seek to understand Brazil’s evolution into the twenty-first century.

ABSTRACT We undertook a comprehensive phylogenetic study to establish the genetic relationship among the viruses of the genusFlavivirus and to compare the classification based on molecular phylogeny with the existing serologic method. By using a combination of quantitative definitions (bootstrap support level and the pairwise nucleotide sequence identity), the viruses could be classified into clusters, clades, and species. Our phylogenetic study revealed for the first time that from the putative ancestor two branches, non-vector and vector-borne virus clusters, evolved and from the latter cluster emerged tick-borne and mosquito-borne virus clusters. Provided that the theory of arthropod association being an acquired trait was correct, pairwise nucleotide sequence identity among these three clusters provided supporting data for a possibility that the non-vector cluster evolved first, followed by the separation of tick-borne and mosquito-borne virus clusters in that order. Clades established in our study correlated significantly with existing antigenic complexes. We also resolved many of the past taxonomic problems by establishing phylogenetic relationships of the antigenically unclassified viruses with the well-established viruses and by identifying synonymous viruses.

AbstractThe progress in our understanding of the endogenous protein concept over the past century is reviewed. Non-dietary proteins found in the digesta at the terminal ileum of poultry, known as endogenous protein loss, are comprised of digestive secretions, mucus and sloughed gut epithelial cells. The measurement of this loss is of fundamental importance because it is an indicator of gut metabolism and is essential to adjust apparent estimates of ileal amino acid digestibility. The ileal endogenous amino acid losses comprise of two components, namely basal and specific losses. The basal losses are fixed and associated with feed dry matter intake, whereas the specific losses are variable and induced by the presence of dietary components such as fibre and anti-nutrients. Currently there is no methodology available to directly measure the specific endogenous losses and these losses are calculated by determining the basal and total (basal plus specific) losses and, then subtracting the basal losses from total losses. The seminal features, specific applications and shortcomings of available methodologies are briefly outlined as well as the practical challenges faced in using the published endogenous amino acid loss values for true digestibility corrections. The relevance of taurine as a component of endogenous protein flow in poultry is identified for the first time.
