Numerals in many languages around the world can be argued to reflect a progressive build-up of historical stages (cf. Hurford 1987), each of which may also represent the synchronic upper limit of a numeral system in another language. This paper presents an intriguing test case of this claim by exploring the historical development of numerals in the languages of the Nadahup (Makú) family of the northwest Amazonian Vaupés region, in which the numeral strategies that can be inferred diachronically for one language are also represented synchronically in its sisters. The paper also demonstrates that even the most basic of the Nadahup numerals have transparent etymologies (a cross-linguistically unusual feature suggestive of their relatively recent development), and that areal diffusion contributed to the expansion of the systems, supporting the characterization of the Vaupés as a linguistic area.

AbstractCaffeine is the most consumed alkaloid stimulant in the world. It is synthesized through the activity of three known N-methyltransferase proteins. Here we are reporting on the 422-Mb chromosome-level assembly of the Coffea humblotiana genome, a wild and endangered, naturally caffeine-free, species from the Comoro archipelago. We predicted 32,874 genes and anchored 88.7% of the sequence onto the 11 chromosomes. Comparative analyses with the African Robusta coffee genome (C. canephora) revealed an extensive genome conservation, despite an estimated 11 million years of divergence and a broad diversity of genome sizes within the Coffea genus. In this genome, the absence of caffeine is likely due to the absence of the caffeine synthase gene which converts theobromine into caffeine through an illegitimate recombination mechanism. These findings pave the way for further characterization of caffeine-free species in the Coffea genus and will guide research towards naturally-decaffeinated coffee drinks for consumers.

This article originates from the theoretical and empirical characterization of factors in the World Trade Model (WTM). It first illustrates the usefulness of this type of model for water research to address policy questions related to virtual water trade, water constraints and water scarcity. It also illustrates the importance of certain key decisions regarding the heterogeneity of water and its relation to the technologies being employed and the prices obtained. With regard to WTM, the global economic input–output model in which multiple technologies can produce a “homogeneous output”, it was recently shown that two different mechanisms should be distinguished by which multiple technologies can arise, i.e., from “technology-specific” or from “shared” factors, which implies a mechanism-specific set of prices, quantities and rents. We discuss and extend these characterizations, notably in relation to the real-world characterization of water as a factor (for which we use the terms technology specific, fully shared and “mixed”). We propose that the presence of these separate mechanisms results in the models being sensitive to relatively small variations in specific numerical values. To address this sensitivity, we suggest a specific role for specific (sub)models or key choices to counter unrealistic model outcomes. To support our proposal we present a selection of simulations for aggregated world regions, and show how key results concerning quantities, prices and rents can be subject to considerable change depending on the precise definitions of resource endowments and the technology-specificity of the factors. For instance, depending on the adopted water heterogeneity level, outcomes can vary from relatively low-cost solutions to higher cost ones and can even reach infeasibility. In the main model discussed here (WTM) factor prices are exogenous, which also contributes to the overall numerical sensitivity of the model. All this affects to a large extent our interpretation of the water challenges, which preferably need to be assessed in integrated frameworks, to account for the main socioeconomic variables, technologies and resources.

AbstractDespite its relatively small size, Belgium has historically been considered to have the most diverse array of beer varieties in the world. We explore whether Belgium's institutional history has contributed to its beer diversity. The Belgian area has experienced a heterogeneous and variable array of institutional regimes over the last millennia. In many cases institutional borders crossed through the Belgian area. We trace the historical development of many of Belgium's well-known beer varieties to specific institutional causes. We also show that the geographic production of important varieties, such as Old Brown, Red Brown, Trappist, Lambic, Saison, and Gruitbeer, continues to be influenced by Belgium's institutional past.

Area studies, as a newly fashionable field of academic research, needs to recognize its less likely precedents if it is going to secure for itself a fresh start. The question of “desire” is relevant here because it indicates the less value-free aspects in its genealogy. As shown in Emma Bovary's embellished representation of Paris at her provincial home, an understanding of an area often reflects the particular needs and desires of the one who understands that area. Such restricted and restricting views of an area repeats itself outside the world of literary fictions, as is shown by the example of Guizot's picture of Europe in which his own country is given a privileged place as the very center of Western civilization itself. An instructive case showing the thin line between the projected desire of one who strives to know a geographical area and the scientific purity of the labor itself is further offered by Napoleon Bonaparte's heavy reliance on Orientalist scholarship in his invasion of Egypt. Moving further east from Egypt to China, we witness the denigrating remarks on China made by the great German thinkers of the past century, Hegel and Weber. Although their characterization of Chinese culture could find echoes in unbiased empirical research, they reveal all the same the trace of Europeans' desire to affirm their superiority over the supposedly inferior and false civilization of the East. Similarly, the Americans who divided the Korean peninsular at the 38th Parallel, with unquestioning confidence in their knowledge of the area and in the justice of their action, rightfully deserve their place in the tradition of Western area studies of serving the needs to dominate, control and exploit an objectified overseas territory. He assumed that words had kept their meaning, that desires still pointed in a single direction, and that ideas retained their logic; and he ignored the fact that the world of speech and desires has known invasions, struggles, plundering, disguises, ploys. From these elements, however, genealogy retrieves an indispensable restraint: it must record the singularity of events outside of any monotonous finality; it must seek them in the most unpromising places, in what we tend to feel is without history—in sentiments, love, conscience, instincts; it must be sensitive to their recurrence, not in order to trace the gradual curve of their evolution, but to isolate the different scenes where they engaged in different roles. — Michel Foucault, “Nietzsche, Genealogy, History” (Foucault 139–40).

Analyzed is one of the most comprehensive modern approaches to the problem of the existence of evolution of human society as such and of specific human communities, i.e. “General Theory of Historical Development” by American historian and sociologist Stephen Sanderson. While agreeing, in general, with its main ideas, we believe that it is important to note that the issue of existence of individual communities demonstrating devolution (regression to an earlier historical state), stagnation or degeneration at certain historical stages is practically ignored in the framework of the theory under consideration. This creates its vulnerability in the face of specific empirical data, indicating a deviation from the evolutionary trend. We believe that overcoming this theoretical difficulty is possible in the process of comprehending the theory of S. Sanderson in the context of ideas of the world-system approach of Immanuel Wallerstein. We want to show that examples of devolution, stagnation and degeneration of societies do not deny general progressive evolutionary tendencies, characteristic for the world-system as a whole, but only indicate the transition of a particular society to a lower level within the world-system (from the core to the semi-periphery, or from the semi-periphery to the periphery).

Abstract Phakopsora pachyrhizi is an obligatory biotrophic fungus that causes Asian soybean rust (ASR) disease. ASR control primarily involves chemical control and the use of resistant soybean cultivars carrying an Rpp (resistance to P. pachyrhizi) gene. This study aimed to characterize the ASR resistance of three soybean Asian landraces. By screening the world core collection (WC) of soybean, which consists of 80 varieties, three landraces were identified in Southeast Asia as resistant to ASR. Genetic mapping using the F2 population derived from a cross with an ASR-susceptible variety, BRS 184, indicated that KS 1034 (WC2) has ASR resistance conferred by a single dominant resistance gene, mapped on chromosome 18, in the same region where Rpp1 was mapped previously. The BRS 184 × WC61 (COL/THAI/1986/THAI-80) F2 population, on the other hand, showed an ASR resistance locus mapped by quantitative trait locus analysis on chromosome 6, in the region where the resistance conferred by PI 416764 Rpp3 resides, with a logarithm of the odds score peak at the same position as the marker, Satt079, while the BRS 184 × WC51 (HM 39) population showed the resistance to ASR allocated between Satt079 and Sat_263 markers, also in the region where Rpp3 was mapped previously. Both WC51 and WC61 have the same infection profile as FT-2 and PI 462312 when tested against the same ASR isolate panel. These three WCs can be used in MAS programs for introgression of Rpp1 and Rpp3 and the development of ASR-resistant cultivars in the breeding program.

Specifics of present moment of historical development is cardinal change of a geopolitical picture of the world. The period of partnership between Russia and the West came to an end. Partnership is succeeded by new structure of the international relations which will be constructed on much more pragmatic basis. At the same time it is obvious that the unipolar world was absolutely not effective. This world finally disbalanced all system of the international relations that was expressed in the number of the regional and local conflicts unprecedented before, and in return in the last two years of direct confrontation between Russia and the West.

Исследуется кризис вербальности контента в интернет-дискурсе, его активная визуализация, связанная с новыми открытиями в области компьютерных технологий. Цель работы - дать полиаспектную характеристику этому явлению и обозначить перспективы его влияния на речемыслительную деятельность подрастающего поколения, составляющего большую часть пользователей социальных сетей. Актуальность данной проблематики обусловлена обеспокоенностью филологической общественностью тем, что мир становится все менее лингвистическим. Новизна заключается в том, что впервые интернет-дискурс рассматривается в контексте кризиса вербальности контента. При таких темпах визуализации медиатекстов вполне вероятно обострение кризиса вербальности, последствия которого могут негативно сказаться на мыслетворческой деятельности у подрастающего поколения, которая возможна только при высокой языковой компетенции. The paper examines the crisis of content verbality in the Internet discourse, its active visualization associated with new discoveries in the field of computer technology. The aim of the work is to give a multi-aspect characterization of this phenomenon and outline the prospects of its influence on the speech-thinking activity of the younger generation, which makes up the majority of users of social networks. The relevance of this issue is due to the concern of the philological community that the world is becoming less and less linguistic. The novelty lies in the fact that for the first time Internet discourse is considered in the context of the crisis of content verbality. At such a rate of visualization of media texts, it is likely that the crisis of verbality will aggravate, the consequences of which can negatively affect the thinking activity of the younger generation, which is possible only with high linguistic competence.

An increase of nosocomial infections caused by Stenotrophomonas maltophilia strains has recently been observed all over the world. The isolation of these bacteria from the blood is of particular concern. In this study we performed the phenotypic and genotypic characterization of 94 S. maltophilia isolates, including isolates from patients hospitalized in a tertiary Warsaw hospital (n = 79) and from outpatients (n = 15). All isolates were found to be susceptible to trimethoprim-sulfamethoxazole and minocycline, while 44/94 isolates demonstrated a reduction in susceptibility to levofloxacin. A large genetic variation was observed among the isolates tested by pulsed-field gel electrophoresis. A clonal relationship with 100% similarity was observed between isolates within two sub-pulsotypes: the first included nine bloodstream isolates and the second involved six. Multilocus sequence typing showed two new sequence types (ST498 and ST499) deposited in public databases for molecular typing. Moreover, the presence of genes encoding ten different efflux pumps from the resistance-nodulation-division family and the ATP-binding cassette family was shown in the majority of the 94 isolates. The obtained knowledge about the prevalence of efflux pump genes in clinical S. maltophilia strains makes it possible to predict the scale of the risk of resistance emergence in strains as a result of gene overexpression.

The emergence of the Charismatic movement has generated a new awareness and interest in the Person and work of the Holy Spirit, but has also brought a realisation that there is a still-neglected Person of the Trinity, the Father. Part of the reason for this lies in the historical development in the doctrine of the Trinity, which led to a belief that external actions of God are not differentiated between the Persons, and also in the fact that the Father only generally acts in the world by Son and Spirit, so has no clear role. It seems natural to attribute creation to the Father, but even here, the Bible sees the Son as the actual creator. Nevertheless, the Father can be seen as the source of the concepts and means behind the material; interestingly there are hints of this in classical Greek thought and other faiths. This is ongoing, perhaps particularly in the evolutionary process of the world. Thus, paralleling the incarnation, the Father is present in the material universe, as its ethos. He can also be seen to be affected by creation, sharing in its nature in his kenōsis, and in its suffering. Creation then inspires a sense of wonder not only from its existence, extent and nature, but from its interactions and underlying concepts; this is worship of the Father. Sin is then when this is overlooked, or when actions disrupt it; these are an offence to the Father.
