In the present review paper by members of the collaborative research center "Register: Language Users' Knowledge of Situational-Functional Variation" (CRC 1412), we assess the pervasiveness of ...register phenomena across different time periods, languages, modalities, and cultures. We define "register" as recurring variation in language use depending on the function of language and on the social situation. Informed by rich data, we aim to better understand and model the knowledge involved in situation- and function-based use of language register. In order to achieve this goal, we are using complementary methods and measures. In the review, we start by clarifying the concept of "register", by reviewing the state of the art, and by setting out our methods and modeling goals. Against this background, we discuss three key challenges, two at the methodological level and one at the theoretical level: (1) To better uncover registers in text and spoken corpora, we propose changes to established analytical approaches. (2) To tease apart between-subject variability from the linguistic variability at issue (intra-individual situation-based register variability), we use within-subject designs and the modeling of individuals' social, language, and educational background. (3) We highlight a gap in cognitive modeling, viz. modeling the mental representations of register (processing), and present our first attempts at filling this gap. We argue that the targeted use of multiple complementary methods and measures supports investigating the pervasiveness of register phenomena and yields comprehensive insights into the cross-methodological robustness of register-related language variability. These comprehensive insights in turn provide a solid foundation for associated cognitive modeling.
Abstract Negative concord (NC) is used in many English varieties but usually considered ungrammatical in ‘standard’ contemporary English, where negative polarity items (NPIs) are used. In this paper, ...we take a novel experimental approach to the use of NC versus NPI constructions, in relation to register, sets of speech repertoires linked to specific situational and functional parameters. We report on two rating experiments with American and British English participants using interlocutor relations as a formality manipulation. Results show that (i) across both samples, NC constructions were rated as less appropriate than NPI associates, and (ii) there was a register effect in the American English data in that NC was rated less appropriate in formal than informal contexts. Our study is the first to provide experimental evidence for the register-sensitivity of NC constructions in American English.
The concept of bias is familiar to linguists primarily from the literature on questions. Following the work of Giannakidou and Mari (Truth and Veridicality in Grammar and Thought: Modality, Mood, and ...Propositional Attitudes, University of Chicago Press, Chicago, 2021), we assume “nonveridical equilibrium” (implying that
p
and
¬p
as equal possibilities) to be the default for epistemic modals, questions and conditionals. The equilibrium of conditionals, as that of questions, can be manipulated to produce bias (i.e., reduced or higher
speaker commitment
). In this paper, we focus on three kinds of modal elements in German that create bias in conditionals and questions: the adverb
wirklich
‘really’, the modal verb
sollte
‘should’, and conditional connectives such as
falls
‘if/in case’. We conducted two experiments collecting participants’ inference about speaker commitment in different manipulations, Experiment 1 on
sollte/wirklich
in
ob-
questions and
wenn-
conditionals, and Experiment 2 on
sollte/wirklich
in
wenn/falls/
V1-conditionals. Our findings are that both
ob-
questions and
falls-
conditionals express reduced speaker commitment about the modified (antecedent) proposition in comparison to
wenn-
conditionals, which did not differ from V1
-
conditionals. In addition,
sollte/wirklich
in the antecedent of conditionals both create negative bias about the antecedent proposition. Our studies are among the first that deal with bias in conditionals (in comparison to questions) and contribute to furthering our understanding of bias.
Treatment of patients with Parkinson’s disease in specialized units is quite common in Germany. Data on the benefit of this hospitalization of patients with Parkinson’s disease on motor and non-motor ...symptoms in conjunction with standardized tests are rare. Objective was to determine the efficacy of this therapeutic setting. We scored disease severity and performed clinical tests, respectively, instrumental procedures under standardized conditions in consecutively referred in-patients initially and at the end of their hospital stay. There was a decrease of motor and non-motor symptoms. The extent of improvement of non-motor and motor symptoms correlated to each other. Performance of complex movement sequences became better, whereas execution of simple movement series did not ameliorate. The interval for the timed up and go test went down. We demonstrate the effectiveness of an in-patient stay in a specialized unit for Parkinson’s disease. Objective standardized testing supplements subjective clinical scoring with established rating scales.
We previously reported the development of a prototype antibiotic sensitivity assay to detect drug-resistant Mycobacterium tuberculosis using infection by mycobacteriophage to create a novel nucleic ...acid transcript, a surrogate marker of mycobacterial viability, detected by reverse transcriptase PCR (M. C. Mulvey et al., mBio 3: e00312-11, 2012). This assay detects antibiotic resistance to all drugs, even drugs for which the resistance mechanism is unknown or complex: it is a phenotypic readout using nucleic acid detection. In this report, we describe development and characteristics of an optimized reporter system that directed expression of the RNA cyclase ribozyme, which generated circular RNA through an intramolecular splicing reaction and led to accumulation of a new nucleic acid sequence in phage-infected bacteria. These modifications simplified the assay, increased the limit of detection from 10(4) to <10(2) M. tuberculosis cells, and correctly identified the susceptibility profile of M. tuberculosis strains exposed for 16 h to either first-line or second-line antitubercular drugs. In addition to phenotypic drug resistance or susceptibility, the assay reported streptomycin MICs and clearly detected 10% drug-resistant cells in an otherwise drug-susceptible population.
One of the most established principles of Supreme Court jurisprudence is that except in matters governed by the Federal Constitution or by acts of Congress, the law to be applied in any case is the ...law of the state. There is no federal general common law. Nonetheless, the question of whether to apply federal common law has resurfaced in the context of corporate successor liability under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund or the Act). Part I of this Note explores the background of CERCLA liability, including the history and purposes of the statute, and further identifies the ambiguity in the statutory language. Part II discusses the controlling principles regarding application of federal common law and the extent to which different courts have followed those principles in this context. Part III introduces different theories of corporate successor liability and their relationship to both state and federal common law.
Mitochondrial DNA copy number (mtDNA-CN), a measure of the number of mitochondrial genomes per cell, is a minimally invasive proxy measure for mitochondrial function and has been associated with ...several aging-related diseases. Although quantitative real-time PCR (qPCR) is the current gold standard method for measuring mtDNA-CN, mtDNA-CN can also be measured from genotyping microarray probe intensities and DNA sequencing read counts. To conduct a comprehensive examination on the performance of these methods, we use known mtDNA-CN correlates (age, sex, white blood cell count, Duffy locus genotype, incident cardiovascular disease) to evaluate mtDNA-CN calculated from qPCR, two microarray platforms, as well as whole genome (WGS) and whole exome sequence (WES) data across 1,085 participants from the Atherosclerosis Risk in Communities (ARIC) study and 3,489 participants from the Multi-Ethnic Study of Atherosclerosis (MESA). We observe mtDNA-CN derived from WGS data is significantly more associated with known correlates compared to all other methods (p < 0.001). Additionally, mtDNA-CN measured from WGS is on average more significantly associated with traits by 5.6 orders of magnitude and has effect size estimates 5.8 times more extreme than the current gold standard of qPCR. We further investigated the role of DNA extraction method on mtDNA-CN estimate reproducibility and found mtDNA-CN estimated from cell lysate is significantly less variable than traditional phenol-chloroform-isoamyl alcohol (p = 5.44x10-4) and silica-based column selection (p = 2.82x10-7). In conclusion, we recommend the field moves towards more accurate methods for mtDNA-CN, as well as re-analyze trait associations as more WGS data becomes available from larger initiatives such as TOPMed.
Chronic obstructive pulmonary disease (COPD) is associated with age and smoking, but other determinants of the disease are incompletely understood. Clonal hematopoiesis of indeterminate potential ...(CHIP) is a common, age-related state in which somatic mutations in clonal blood populations induce aberrant inflammatory responses. Patients with CHIP have an elevated risk for cardiovascular disease, but the association of CHIP with COPD remains unclear. We analyzed whole-genome sequencing and whole-exome sequencing data to detect CHIP in 48 835 patients, of whom 8444 had moderate to very severe COPD, from four separate cohorts with COPD phenotyping and smoking history. We measured emphysema in murine models in which Tet2 was deleted in hematopoietic cells. In the COPDGene cohort, individuals with CHIP had risks of moderate-to-severe, severe, or very severe COPD that were 1.6 (adjusted 95% confidence interval CI, 1.1-2.2) and 2.2 (adjusted 95% CI, 1.5-3.2) times greater than those for noncarriers. These findings were consistently observed in three additional cohorts and meta-analyses of all patients. CHIP was also associated with decreased FEV1% predicted in the COPDGene cohort (mean between-group differences, -5.7%; adjusted 95% CI, -8.8% to -2.6%), a finding replicated in additional cohorts. Smoke exposure was associated with a small but significant increased risk of having CHIP (odds ratio, 1.03 per 10 pack-years; 95% CI, 1.01-1.05 per 10 pack-years) in the meta-analysis of all patients. Inactivation of Tet2 in mouse hematopoietic cells exacerbated the development of emphysema and inflammation in models of cigarette smoke exposure. Somatic mutations in blood cells are associated with the development and severity of COPD, independent of age and cumulative smoke exposure.
Aortic calcification is an important independent predictor of future cardiovascular events. We performed a genome-wide association meta-analysis to determine SNPs associated with the extent of ...abdominal aortic calcification (n = 9,417) or descending thoracic aortic calcification (n = 8,422). Two genetic loci, HDAC9 and RAP1GAP, were associated with abdominal aortic calcification at a genome-wide level (P < 5.0 × 10
). No SNPs were associated with thoracic aortic calcification at the genome-wide threshold. Increased expression of HDAC9 in human aortic smooth muscle cells promoted calcification and reduced contractility, while inhibition of HDAC9 in human aortic smooth muscle cells inhibited calcification and enhanced cell contractility. In matrix Gla protein-deficient mice, a model of human vascular calcification, mice lacking HDAC9 had a 40% reduction in aortic calcification and improved survival. This translational genomic study identifies the first genetic risk locus associated with calcification of the abdominal aorta and describes a previously unknown role for HDAC9 in the development of vascular calcification.
