The availability of preposition omission in ellipsis is assumed to follow from the possibility of preposition stranding in corresponding non-elliptical clauses (Merchant 2001). To test this assumption I sampled 409 ellipsis remnants from three corpora of American English, and developed generalized mixed-effects models of preposition omission in ellipsis. The results show that preposition omission is, among others, sensitive to gradient constraints independently found to influence preposition placement in interrogative clauses, without being correlated with the possibility of preposition stranding. This finding challenges evidence for syntactic parallels between elliptical constructions and their nonelliptical counterparts, and hence, for deletion-based approaches to ellipsis.

Southern American English is spoken in a large geographic region in the United States. Its characteristics include back-vowel fronting (e.g., in goose, foot, and goat), which has been ongoing since the mid-nineteenth century; meanwhile, the low back vowels (in lot and thought) have recently merged in some areas. We investigate these five vowels in the Digital Archive of Southern Speech, a legacy corpus of linguistic interviews with sixty-four speakers born 1886-1956. We extracted 89,367 vowel tokens and used generalized additive mixed-effects models to test for socially-driven changes to both their relative phonetic placements and the shapes of their formant trajectories. Our results reinforce previous descriptions of Southern vowels while contributing additional phonetic detail about their trajectories. Goose-fronting is a change in progress, with greatest fronting after coronal consonants. Goat is quite dynamic; it lowers and fronts in apparent time. Generally, women have more fronted realizations than men. Foot is largely monophthongal, and stable across time. Lot and thought are distinct and unmerged, occupying different regions of the vowel space. While their relative positions change across generations, all five vowels show a remarkable consistency in formant trajectory shapes across time. This study’s results reveal social and phonetic details about the back vowels of Southerners born in the late nineteenth and early twentieth centuries: goose-fronting was well underway, goat-fronting was beginning, but foot remained backed, and the low back vowels were unmerged.

Abstract Background Tofogliflozin, an SGLT2 inhibitor, is associated with favorable metabolic effects, including improved glycemic control and serum lipid profile and decreased body weight, visceral adipose tissue, and blood pressure (BP). This study evaluated the effects of tofogliflozin on the brachial-ankle pulse wave velocity (baPWV) in patients with type 2 diabetes (T2DM) without a history of apparent cardiovascular disease. Methods The using tofogliflozin for possible better intervention against atherosclerosis for type 2 diabetes patients (UTOPIA) trial is a prospective, randomized, open-label, multicenter, parallel-group, comparative study. As one of the prespecified secondary outcomes, changes in baPWV over 104 weeks were evaluated in 154 individuals (80 in the tofogliflozin group and 74 in the conventional treatment group) who completed baPWV measurement at baseline. Results In a mixed-effects model, the progression in the right, left, and mean baPWV over 104 weeks was significantly attenuated with tofogliflozin compared to that with conventional treatment (– 109.3 [– 184.3, – 34.3] (mean change [95% CI] cm/s, p = 0.005; – 98.3 [– 172.6, – 24.1] cm/s, p = 0.010; – 104.7 [– 177.0, – 32.4] cm/s, p = 0.005, respectively). Similar findings were obtained even after adjusting the mixed-effects models for traditional cardiovascular risk factors, including body mass index (BMI), glycated hemoglobin (HbA1c), total cholesterol, high-density lipoprotein (HDL)-cholesterol, triglyceride, systolic blood pressure (SBP), hypertension, smoking, and/or administration of drugs, including hypoglycemic agents, antihypertensive agents, statins, and anti-platelets, at baseline. The findings of the analysis of covariance (ANCOVA) models, which included the treatment group, baseline baPWV, and traditional cardiovascular risk factors, resembled those generated by the mixed-effects models. Conclusions Tofogliflozin significantly inhibited the increased baPWV in patients with T2DM without a history of apparent cardiovascular disease, suggesting that tofogliflozin suppressed the progression of arterial stiffness.

Wollack et al. (2015) suggested the erasure detection index (EDI) for detecting fraudulent erasures for individual examinees. Wollack and Eckerly (2017) and Sinharay (2018) extended the index of Wollack et al. (2015) to suggest three EDIs for detecting fraudulent erasures at the aggregate or group level. This article follows up on the research of Wollack and Eckerly (2017) and Sinharay (2018) and suggests a new aggregate-level EDI by incorporating the empirical best linear unbiased predictor from the literature of linear mixed-effects models (e.g., McCulloch et al., 2008). A simulation study shows that the new EDI has larger power than the indices of Wollack and Eckerly (2017) and Sinharay (2018). In addition, the new index has satisfactory Type I error rates. A real data example is also included.

The global severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic leading to coronavirus disease 2019 (COVID-19) is straining hospitals. Judicious resource allocation is paramount but difficult due to the unpredictable disease course. Once hospitalized, discerning which patients may progress to critical disease would be valuable for resource planning. Medical records were reviewed for consecutive hospitalized patients with COVID-19 in a large healthcare system in Texas. The main outcome was progression to critical disease within 10 days from admission. Albumin trends from admission to 7 days were analyzed using mixed-effects models, and progression to critical disease was modeled by multivariable logistic regression of laboratory results. Risk models were evaluated in an independent group. Of 153 non-critical patients, 28 (18%) progressed to critical disease. The rate of decrease in mean baseline-corrected (Δ) albumin was −0.08 g/dL/day (95% CI −0.11 to −0.04; p<0.001) or four times faster, in those who progressed compared with those who did not progress. A model of Δ albumin combined with lymphocyte percentage predicting progression to critical disease was validated in 60 separate patients (sensitivity, 0.70; specificity, 0.74). ALLY (delta albumin and lymphocyte percentage) is a simple tool to identify patients with COVID-19 at higher risk of disease progression when: (1) a 0.9 g/dL or greater albumin drop from baseline within 5 days of admission or (2) baseline lymphocyte of ≤10% is observed. The ALLY tool identified >70% of hospitalized cases that progressed to critical COVID-19 disease. We recommend prospectively tracking albumin. This is a globally applicable tool for all healthcare systems.
