Through intriguing paths of change, manner expressions may give rise to both quotatives and a diverse range of complementizers. These paths of change are still far from mapped or fully understood, but after years of relative ignorance, they have recently been the subject of increased interest. In this paper, we introduce a special issue the aim of which is to add to the growing knowledge and understanding of the development of manner expressions into complementizers or quotatives. Centering our discussion on Saxena's diachronic hypothesis from 1995, we first briefly go through a number of central studies of the issue. Subsequently, we summarize the main findings of the contributions to the special issue: (i) additional evidence of the development of manner expressions into complementizers or quotatives; (ii) an emphasis on the variation found in examples of this development; (iii) a number of developmental paths that do not conform to Saxena's hypothesis (but also a couple that might be compatible with it). In the final part of the paper, we introduce each of the individual contributions to the special issue. [ABSTRACT FROM AUTHOR]

Indexing P arguments on bivalent predicates is often considered more restricted and less often obligatory than A indexing. However, differential A indexing, i.e., the absence versus the presence of an index referring to the A argument role, is not uncommon either: usually present A indexes can be omitted in particular discourse settings. However, differential A indexing has been a Cinderella subject in the typological study of differential marking, as opposed to differential P indexing or differential A flagging. This paper scrutinizes various cases of both differential A and P indexing and examines structural and functional differences and similarities. It will be shown that exploring differential indexing helps to understand how indexing in general is linked to referential prominence which surfaces as factors such as identifiability, animacy or topicality. Cases where indexing is particularly sensitive to referential prominence, and where it thus is employed only if the referent fulfills certain criteria, bring out the fact that A and P indexing have a common purpose, namely tracking referents through discourse. In this context, the paper also points out that differential A indexing presents an exception from generalizations concerning the amount of material in coding asymmetries. [ABSTRACT FROM AUTHOR]

There is an extensive range of carbon substances with poorly ordered structures that are not well understood. Yet they are important indicators of conditions of related geological processes. The carbon minerals include nanocrystalline graphite, natural analogs of glass-like carbon (GLC)—shungite and impact ultrahigh-pressure GLC, recently discovered ultranocrystalline diamond, as well as natural carbon nanocomposites of diamond, lonsdaleite, and graphite. Studying these natural carbon substances using a standard Raman approach with excitation by visible radiation may lead to a significant distortion of the understanding of their phase states. This paper presents in detail for the first time the spectral features of natural, poorly ordered, and multiphase sp2-sp3 carbon composites by multi-wave Raman spectroscopy using laser excitations from visible to ultraviolet light applied to natural low-ordered carbon substances—nanocrystalline graphite and shungite, nanocrystalline and ultranocrystalline diamond, and multiphase carbon aggregates. The carbon state resolution advantages of ultraviolet Raman spectroscopy for phase analysis of nanostructured and poorly ordered polycomponent carbon substances containing sp2- and sp3-carbons are presented. Raman spectroscopy with ultraviolet excitation can also be applied in the analysis of industrial carbon materials, such as glassy carbon and functional carbon nanocomposites, including ultranocrystalline diamond, lonsdaleite, and amorphous sp3-carbon components.

Previous research has identified differences in language use between speakers representing different genders and sexual orientations, as well as stereotypical beliefs about the existence of such differences. The present paper investigates such stereotypical beliefs among speakers of two varieties of Spanish and explores whether linguistic stereotypes of gender and sexual orientation are stronger in a society with more conservative gender roles. We conducted an experiment where 252 speakers of European and Mexican Spanish were shown pairs of texts and sentences depicting the same event but differing in the use of morphosyntactic resources, creating stereotypically “masculine” and “feminine” variants of the same text or sentence. The informants were asked which of the variants was more likely uttered by a woman (rather than a man), a lesbian woman (rather than a straight woman), or a gay man (rather than a straight man). Some of the morphosyntactic features were strongly associated with speaker gender (e.g., use of first- and second-person singular) and others with lesbian (e.g., use of impersonal structures) or gay speakers (e.g., direct reported speech). Contrary to expectations, the responses did not differ according to informants’ age, gender, or nationality. While the present study did not reveal any differences between the two societies, more cross-linguistic and cultural research is needed to elucidate the effect of society on morphosyntactic variation and stereotypes thereof.

This paper explores variation in the patterns of reflexivity marking in the Mano language and possible influence from the Kpelle language by using an experimental design with a picture questionnaire. While Kpelle does not have a morphological distinction between reflexive and basic pronouns, the Mano variety spoken by Mano-dominant individuals does possess such a distinction in 3sg. In contrast, the Mano variety spoken by Kpelle-dominant individuals shows a pattern borrowing from Kpelle into Mano, whereby the basic pronoun is used for both coreferential and disjoint readings. In a bilingual village, however, despite daily usage of both languages, almost all speakers from our sample manifest a uniform pattern that aligns closely with the monolingual Mano pattern of reflexivity marking. Therefore, the intensity of contact alone does not predict the amount of influence of Kpelle on Mano. Contrary to predictions by Labov (2010. Principles of linguistic change. Volume 3, Cognitive and cultural factors. Hoboken: Wiley-Blackwell: 5), we conclude that the languages spoken in a multilingual speech community do not necessarily converge and that a balanced multilingual community may provide enough input to acquire monolingual-like competence, at least according to the specific parameter under investigation. In the long run, however, convergence between Mano and Kpelle could indeed be taking place, with Mano losing its reflexivity contrasts, having already lost the contrast in 3pl.

This paper summarizes an approach to crystal growth that was published in parts in various articles over the course of 25 years by the present author and his colleagues. Evidence for this approach, which is confirmed in detail by data in the cited publications and in the figures and equations in the supplementary material that accompanies this paper (see the Online Materials Deposit item AM-24-18851. Online Materials are free to all readers. Go online, via the table of contents or article view, and find the tab or link for supplemental materials.), comes mainly from the shapes of crystal size distributions (CSDs). Such distributions reveal the growth histories of natural minerals and synthetic compounds, histories that can be used to make geological interpretations and to guide industrial syntheses. CSDs have three fundamental shapes: log-normal, asymptotic, and Ostwald. These shapes result from different degrees of supersaturation near the time of nucleation. The first two distribution shapes form according to the Law of Proportionate Efect (LPE) at moderate supersaturation, and the latter rare distribution forms by Ostwald ripening at large supersaturation. Initially, the first two distributions have mean diameters of up to tens of nanometers and grow by surface-limited growth kinetics. The slow step in this reaction is the incorporation of nanoparticles (bits of crystal or adparticles) onto the crystal surface. As the crystals become larger, their demand for nutrients, as calculated by the LPE, increases exponentially. Then the slow step in the reaction changes to the rate of transfer of nutrients to the crystal (supply- or transport-limited growth). Crystal diameters often grow the most during this latter stage, and the initial CSD shapes that originally formed during surface-limited growth are retained and scaled up proportionately. Proportionate growth during the supply-limited stage can be simulated approximately by multiplying the diameter of each crystal in a distribution by a constant. Crystals can also grow by a constant rate law in which a constant length is added to each crystal diameter in the distribution. This rare process causes the original CSD to narrow so that its initial shape is not preserved. The growth law that prevails, either proportionate or constant, is determined by the manner in which nutrients are supplied to the crystal. Supply is by advective flow during proportionate growth, with the nutrient solution moving with respect to the crystals. Constant growth relies on the random difusion of nutrients through a quiescent solution. Proportionate growth is by far the most common growth law, and therefore, nutrient supply by difusion alone during crystal growth is uncommon. Distributions formed by Oswald ripening and those formed by other rare processes are also discussed. During Ostwald ripening, nucleation caused by mixing reactants at large supersaturation forms crystals that are extremely fine and numerous. The larger crystals grow at the expense of the finer, less stable crystals, thereby forming, on completion, the universal steady-state CSD shape predicted by the Lifshitz-Slyozov-Wagner (LSW) theory. This unique CSD shape, as well as other rare shapes, then are scaled up to larger sizes by supply limited proportionate growth. [ABSTRACT FROM AUTHOR]

In spontaneous discourse, a speaker sometimes encounters word-formulation trouble, and she may use a ‘placeholder’ (PH) such as whatchamacallit and you-know-what, a dummy expression to be inserted into the slot of a ‘target form’ in the sentence structure of an utterance. It has been widely held that there are two types of usage motives: (i) a speaker cannot produce a target form when, e.g., she does not recall it, or (ii) a speaker does not want to produce a target form when, e.g., it is considered taboo. Previous studies have described the grammatical and functional properties of PHs in a variety of languages, but no study has examined their usage-motive patterns crosslinguistically. In this paper, I propose an implicational hierarchy relating to the usage motives of PHs based on the relevance-theoretic notions of ‘ability’ and ‘preference’ and derive several predictions from this hierarchy, which are tested against PH data in 56 languages. The predictions are mostly confirmed, with some (putative) counterexamples explained by non-cognitive–pragmatic factors (e.g., lexical-semantic factors). As an implication, the hierarchy may also serve as a basis for drawing predictions in other linguistic fields (e.g., language acquisition). [ABSTRACT FROM AUTHOR]

Accurately determining the timing and mechanism of metallogenesis of ore deposits is essential for developing a robust genetic model for their exploration. In this paper, we analyze the formation conditions of cassiterite in five major deposits of southern Hunan Province, one of the most important tungsten-tin (W-Sn) provinces in South China, using a combination of cathodoluminescence imaging, in situ U-Pb geochronology, and trace-element concentration data. In situ cassiterite U-Pb geochronology constrains the main period of Sn mineralization to between 155.4 and 142.0 Ma, demonstrating a temporal and genetic relationship to silicic intrusive magmatism in the same area. Three stages of magmatic activity and metallogenic evolution are recognized: (1) Early Paleozoic and Triassic: the initial enrichment stage of tungsten and tin; (2) Jurassic: the metasomatic mineralization stage; and (3) Cretaceous: the magmatic-hydrothermal superposition stage. The cassiterite in these deposits takes four forms, i.e., quartz vein-type, greisen-skarn-type, greisen-type, and granite-type, representing a progression characterized by the increasing content and decreasing range of variation of high field strength elements (HFSEs), and reflecting a general increase in the degree of evolution of the associated granites. Rare earth element (REE) concentrations suggest that precipitation of cassiterite was insensitive to the redox state of the fluid and that precipitation of cassiterite in the southern Hunan Sn deposits did not require a high-fO2 environment. These findings provide new insights into tin mineralization processes and exploration strategies. [ABSTRACT FROM AUTHOR]

The application of whole-rock compositions to trace magma evolution or crystal-melt equilibrium may be called into question when foreign crystals are incorporated into host magmas. To address this challenge, establishing the origins (orthocrysts, antecrysts, xenocrysts, etc.) of minerals with variable textures in magmatic plumbing systems is necessary. In this paper, we describe complex oscillatory zoning patterns of clinopyroxenes (Cpx) from the Miocene Majuangou (MJG) alkali basalts from West Qinling, China. Our detailed petrographic, mineralogical, and geochemical analyses unravel the origins of various Cpx crystals with distinct textural patterns, thereby providing information about magma storage, recharging and/or mixing, and transportation, as well as the reactions between crystals and melts/fluids. Based on textural patterns, Cpx may be divided into four types: normal (Type-1 Cpx), simple oscillatory (Type-2 Cpx), complex oscillatory (Type-3 Cpx), and grains that lack zoning (Type-4 Cpx, suggested to be orthocrysts). Through the textural characterization of Cpx, the comparison between different types of Cpx, and the relationships between Cpx major compositions from different lithologies, we concluded that Type-1–3 Cpx cores are antecrysts or xenocrysts with diverse origins: primitive magma (Type-1 Cpx cores), magma mush (Type-2 Cpx cores), and crustal granulite (Type-3 Cpx cores). The zoning patterns and the compositions of these Cpx crystals indicate at least three batches of magmatic activity, i.e., the Batch-1 low-Mg# magma (Mg#: 47.4–53.3), the Batch-2 primitive magma (Mg#: 57.2–64.5), and the Batch-3 low-Mg# host alkali magma (Mg#: 47.2–54.6). Cpx-melt thermobarometry demonstrates that at least two crustal magma reservoirs existed in the magma plumbing system at depths of 30.1 and 40.9 km. The antecrystic/xenocrystic Cpx cores were captured by, continued to grow in, and subsequently reacted with ascending K-rich melt/fluid. The spongy textures in Cpx cores/mantles are attributed to this reaction, which may be expressed as: Melt 1 (primitive or evolved) + K-rich melts/fluids + Cpx (CaMgSi2O6) = K-feldspar (KAlSi3O8) + ilmenite (FeTiO3) + Melt 2 (derivative). The products of this reaction (K-feldspar and ilmenite) filled the sieves in the spongy zones of Type-1–3 Cpx. This detailed investigation of compositional and textural features of Cpx antecrysts/xenocrysts suggests that the interactions between various interconnected magma reservoirs are widespread beneath the magmatic plumbing system. Our study emphasizes the importance of the incorporation of foreign crystals and the Cpx-melt/fluid reaction in magmatic plumbing system, which can significantly modify the whole-rock compositions and lead to the formation of spongy textures without the need for fractures and cracks in minerals.

The article "Issue 32(1)" in the Communications of the German Mathematical Society (DMV) covers various topics such as the DMV Student Conference 2024 in Ilmenau, the significance of mathematics in museums, job opportunities for mathematics graduates, and the name of the DMV. The president of the DMV emphasizes the need to attract more and younger members and to make greater efforts towards women and diversity. It also reports on the discussion about renaming the DMV, for which suggestions from members are being collected. The 2023 PISA study shows that the average mathematical and reading competencies of adolescents in many OECD countries have declined compared to the previous study in 2018. Scientific competence has also decreased. In Germany, the performance losses in all three areas are above average. The reasons for the deterioration are mainly attributed to the effects of the COVID-19 pandemic, as well as language difficulties, interest, and motivation. The exhibition "From Newton to Einstein - a journey through space and time" was developed at the Max Planck Institute for Gravitational Physics in Potsdam and is now on display in Tübingen. The award winner Carla Cederbaum has also developed other projects, such as a book on mathematical magic tricks and the publication series "Oberwolfach-Snapshots of Modern Mathematics". Mathematicians Carolin Mehlmann and Thomas Richter from the University of Magdeburg participated in an expedition of the Polarstern to the Arctic Ocean to calibrate a new hybrid sea ice model. The hybrid sea ice model combines particle and continuum methods to better resolve the different sea ice regimes on different local scales. The text deals with the deformation theorem in differential geometry. It is shown that a manifold with boundary possesses a metric with certain properties if the double of the manifold carries such a metric. The question of whether the converse of this statement holds is also raised. The text deals with hypothesis testing and the problem of multiple error probability. Various methods for solving this problem are presented, including the Bonferroni correction and the development of better methods taking into account the dependency structure of the tests. It also addresses pseudoline arrangements, which have connections to combinatorics, geometry, and computer science. The text deals with various mathematical topics, including sorting networks, pseudoline arrangements, Rubik's cube, the PISA study, calculating machines, student studies, Felix Klein, and international cooperation in mathematics. Various concepts and applications are explained, such as the creation of sorting networks from pseudoline arrangements, the use of Markov chains to generate random pseudoline arrangements, and the development of calculation aids and calculating machines. The importance of student studies and international cooperation in mathematics is also emphasized. The text provides an insight into various mathematical topics and their applications. The article reports on Renate Tobies, a visiting scientist at Friedrich Schiller University Jena. She studied chemistry and mathematics and obtained her habilitation in the history of mathematics and natural sciences. Tobies has taught in various German cities and in Austria and was the managing editor of NTM History and Ethics of Natural Sciences, Technology, and Medicine. The article deals with a position paper by the professional societies DMV. [Extracted from the article]

This paper uncovers how metaphor forces argument overtness – across languages and parts of speech. It addresses the relationship between semantically unsaturated terms, functors, and the argument terms that complete them. When the component terms’ default senses clash semantically, a metaphor arises. In such cases, the argument must be overt, in contrast to literal uses. It is possible to say Everyone was waiting at the hotel. Finally, Kim arrived. By contrast, people do not use arrived metaphorically without a goal argument: Everything had been pointing to that conclusion all along. *Finally, Kim arrived. What they say is Finally, Kim arrived at it. We illustrate the phenomenon with powerful and diverse evidence: three corpus studies (Indo-Aryan languages, British English, Vera’a) and a sentence-completion experiment with around 250 native speakers of English. Both the corpus studies and the experiment show no or almost no exceptions to metaphor-driven argument overtness. The strength of the effect contrasts with a complete lack of speaker awareness. We propose that metaphor-driven argument overtness – as well as the lack of speaker consciousness – is a universal phenomenon that can be accounted for in terms of human language processing.
