    Another Heavy Road of Decompositionality: Notes from a Dying Adverb

    Get PDF
    This contribution reports on a pilot case study conducted on historical corpus data from Old and Middle English (primarily Taylor et al. 2003, Kroch and Taylor 2000) and concerned with the ramifications of an ambiguous adverb (eft, ‘again’) at the syntax-semantics interface. The disappearance of the adverb is linked to the development of again’s partially similar functions during the Middle English period. Akin to studies on the adverb again (e.g. Fabricius-Hansen 2001, Gergel and Beck 2015, Beck and Gergel 2015), at least some instances of eft are claimed to require a particular type of analysis of so-called decompositional adverbs, namely one based on lexical rather than only on structural factors. Furthermore, the development shows characteristics of a cyclical development (cf. Jespersen 1917, van Gelderen 2011)

    CD8+ T Cells Mediate CD40-independent Maturation of Dendritic Cells In Vivo

    Induction of cytotoxic T lymphocyte (CTL) responses against minor histocompatibility antigens is dependent upon the presence of T cell help and requires the interaction of CD40 on dendritic cells (DCs) with CD40 ligand on activated T helper cells (Th). This study demonstrates that CD40 is neither involved in Th-dependent nor Th-independent antiviral CTL responses. Moreover, the data show that DC maturation occurs in vivo after viral infection in the absence of CD40 and Th. This maturation did not require viral infection of  DCs but was mediated by peptide-specific CD8+ T cells. Surprisingly, naive CD8+ T cells were able to trigger DC maturation within 24 h after activation in vivo and in vitro. Moreover, peptide-activated CD8+ T cells were able to induce maturation in trans, as DCs that failed to present the relevant antigen in vivo also underwent maturation. Upon isolation, the in vivo–stimulated DCs were able to convert a classically Th-dependent CTL response (anti-HY) into a Th-independent response in vitro. Thus, antiviral CD8+ T cells are sufficient for the maturation of DCs in the absence of CD40

    Simulating semantic change: A methodological note

    The current work discusses the Human Diachronic Simulation Paradigm (HUDSPA), a method to experimentally probe into historical meaning change set up to (i) scan for configurations similar to attested alterations of meaning but in (typically, but not necessarily, related) languages or varieties which did not actualize the change(s) under investigations; (ii) measure the reactions of native speakers in order to ascertain the verisimilitude as well as the particular semantic and pragmatic properties of the items scrutinized. Specifically, the present paper discusses the relative propensity of a particularizer (German eben) to be interpreted with comparatively high confidence as a scalar additive particle such as even and of a concessive item like English though to be interpreted similar to a modal particle along the lines of German doch

    Complement receptors regulate differentiation of bone marrow plasma cell precursors expressing transcription factors Blimp-1 and XBP-1

    Humoral immune responses are thought to be enhanced by complement-mediated recruitment of the CD21–CD19–CD81 coreceptor complex into the B cell antigen receptor (BCR) complex, which lowers the threshold of B cell activation and increases the survival and proliferative capacity of responding B cells. To investigate the role of the CD21–CD35 complement receptors in the generation of B cell memory, we analyzed the response against viral particles derived from the bacteriophage Qβ in mice deficient in CD21–CD35 (Cr2−/−). Despite highly efficient induction of early antibody responses and germinal center (GC) reactions to immunization with Qβ, Cr2−/− mice exhibited impaired antibody persistence paralleled by a strongly reduced development of bone marrow plasma cells. Surprisingly, antigen-specific memory B cells were essentially normal in these mice. In the absence of CD21-mediated costimulation, Qβ-specific post-GC B cells failed to induce the transcriptional regulators Blimp-1 and XBP-1 driving plasma cell differentiation, and the antiapoptotic protein Bcl-2, which resulted in failure to generate the precursor population of long-lived plasma cells residing in the bone marrow. These results suggest that complement receptors maintain antibody responses by delivery of differentiation and survival signals to precursors of bone marrow plasma cells

    Quantification and scales in change

    This volume contains thematic papers on semantic change which emerged from the second edition of Formal Diachronic Semantics held at Saarland University. Its authorship ranges from established scholars in the field of language change to advanced PhD students whose contributions have equally qualified and have been selected after a two-step peer-review process.   The key foci are variablity and diachronic trajectories in scale structures and quantification, but readers will also find a variety of further (and clearly non-disjoint) issues covered  including reference, modality, givenness, presuppositions, alternatives in language change, temporality, epistemic indefiniteness, as well as - in more general terms -  the interfaces of semantics with syntax, pragmatics and morphology.    Given the nature of the field, the contributions are primarily based on original corpus studies (in one case also on synchronic experimental data) and present a series of new findings and theoretical analyses of several languages, first and foremost from  the Germanic and Romance subbranches of Indo-European (English, French, German, Italian, Spanish) and from Semitic (with an analysis of universal quantification in Biblical Hebrew)
