The subjunctive alternation in Indian English
(2024) Schmidt, Karola
The study at hand is an exploration of the alternation between the mandative subjunctive and its equivalent modal construction with the verb should in Indian English. The study complements the growing body of research on the morphosyntax of the variety and it enhances our understanding of the relatively under-researched alternation. It adds a special focus on the short-term diachronic development of the subjunctive alternation in Indian English by using data from the South Asian Varieties of English corpus and its 2020 update. The following research questions are being investigated in the paper: Which factors influence the alternation between subjunctive and should in Indian English; are there short-term diachronic adjustments to the subjunctive paradigm? A multifactorial model was fitted on 508 extracted data points with the following predictors: lexical diversity, newspaper, word count, distance, gender, linking word, negation, subject number, subject person, time and trigger lemma. The results show minor diachronic adjustments and highlight well-known predictors of the alternation like voice as important factors.
On regression modeling in varieties research
(2024) Gries, Stefan Th.
One particularly prominent methodological development in linguistics is what has been termed the “quantitative turn”: Not only are more and more studies using statistical tools to explore data and to test hypotheses, the complexity of the statistical methods employed is growing as well. This development is particularly prominent in all kinds of corpus-linguistic studies: 20 years ago chi-squared tests, t-tests, and Pearson's r reigned supreme, but now more and more corpus studies are using multivariate exploratory tools and, for hypothesis testing, multifactorial predictive modeling techniques, in particular regression models (and, increasingly, tree-based methods). However welcome this development is, it, and especially its pace as well as the fact that few places offer rigorous training in statistical methods, comes with its own risks, chief among them that analytical methods are misapplied, which can lead imprecise, incomplete, or wrong analyses. In this paper, I will revisit a recent regression-analytic study in the research area of English varieties (on clause-final also and only in three Asian Englishes) to:
- highlight in particular three fundamental yet frequent mistakes that it exemplifies;
- discuss why and how each of these mistakes should be addressed;
- reanalyze the data (as far as is possible with what is available) and show briefly how that affects the analysis's results and interpretation.
Parentheticals in spoken Indian and Sri Lankan English
(2024) Degenhardt, Julia
While an increasing number of studies into the pragmatics of world Englishes indicate that sociobiographic factors—such as the speakers’ age or gender—influence pragmatic choices, most empirical investigations do not include sociobiographic information beyond said speaker characteristics. This study investigates parenthetical I assume/believe/feel/ guess/suppose/think in the spoken parts of the Indian and Sri Lankan English components of the International Corpus of English to answer the question of to what extent parenthetical function, that is, expressing either the speaker's opinion or insufficient knowledge, is influenced by structural, contextual and sociobiographic factors. Based on 1265 parentheticals, the results of multifactorial statistical analyses indicate that the speakers’ educational background and additional languages spoken at home are important predictors for the choice of parenthetical function. Therefore, the study calls for the inclusion of wide-ranging sociobiographic factors (and combinations thereof) in the description of pragmatic speaker choices in world Englishes.
Space-like electromagnetic form factors of lambda- and sigma-baryons from quark-diquark Faddeev equations
(2024) Liu, Langtian; Fischer, Christian S.
An important goal of ongoing and future experiments is to explore spectra and transition form factors of baryons with non-zero strangeness. Of particular interest is the transition form factor γ(\*) Σ0 -> Λ in the time-like momentum region that can be extracted from Dalitz decays. On the road towards a theoretical description of these form factors we extend a covariant dynamical quark-diquark model for the baryon Faddeev equation to the strange-quark sector. Based on an excellent description of the mass spectrum of selected baryon octet and decuplet states and reasonable results for the nucleon form factors we determine the elastic electromagnetic form factors of Λ and Σ+, Σ0, Σ- hyperons in the space-like region as well as the ones for the octet transition γ(\*) Σ0 -> Λ. We discuss qualitative and quantitative features of the diquark-quark picture and compare systematically with previous results from a three-body Faddeev approach and lattice data where available.
Experimental and theoretical total cross sections for single and double ionization of the open-4d-shell ions Xe12+, Xe13+, and Xe14+ by electron impact
(2024) Jin, Fengtao; Borovik, Alexander; Döhring, B. Michel; Ebinger, Benjamin; Müller, Alfred; Schippers, Stefan
We present new experimental and theoretical cross sections for electron-impact single ionization of Xe12+ and Xe13+ ions, and double ionization of Xe12+, Xe13+ and Xe14+ ions for collision energies from the respective ionization thresholds up to 3500 eV. The calculations use the fully relativistic subconfiguration-averaged distorted-wave approach and, partly, the more detailed level-to-level distorted wave method. We find that, unlike in previous work, our theoretical cross sections agree with our experimental ones within the experimental uncertainties, except for the near-threshold double-ionization cross sections. We attribute this remaining discrepancy to the neglect of direct-double ionization in the present theoretical treatment.
