TL;DR: A guide to ion mobility mass spectrometry experiments, which covers both linear and nonlinear methods: what is measured, how the measurements are done, and how to report the results, including the uncertainties of mobility and collision cross section values.
Abstract: Here we present a guide to ion mobility mass spectrometry experiments, which covers both linear and nonlinear methods: what is measured, how the measurements are done, and how to report the results, including the uncertainties of mobility and collision cross section values. The guide aims to clarify some possibly confusing concepts, and the reporting recommendations should help researchers, authors and reviewers to contribute comprehensive reports, so that the ion mobility data can be reused more confidently. Starting from the concept of the definition of the measurand, we emphasize that (i) mobility values (K0) depend intrinsically on ion structure, the nature of the bath gas, temperature, and E/N; (ii) ion mobility does not measure molecular surfaces directly, but collision cross section (CCS) values are derived from mobility values using a physical model; (iii) methods relying on calibration are empirical (and thus may provide method‐dependent results) only if the gas nature, temperature or E/N cannot match those of the primary method. Our analysis highlights the urgency of a community effort toward establishing primary standards and reference materials for ion mobility, and provides recommendations to do so.

TL;DR: Estimates of direct medical costs for patients with RA are substantially higher than cost estimates before the biologic therapy era, and costs are now driven predominantly by the cost of drugs, primarily biologic agents.
Abstract: Objective To estimate total direct medical costs in persons with rheumatoid arthritis (RA) and to characterize predictors of these costs. Methods Patients (n = 7,527) participating in a longitudinal study of outcome in RA completed 25,050 semiannual questionnaires from January 1999 through December 2001. From these we determined direct medical care costs converted to 2001 US dollars using the consumer price index. We used generalized estimating equations to examine potential predictors of the costs. Monte Carlo simulations and sensitivity analyses were performed to evaluate the varying prevalence and cost of biologic therapy. Results The mean total annual direct medical care cost in 2001 for a patient with RA was 9,519 US dollars. Drug costs were 6,324 US dollars (66% of the total), while hospitalization costs were only 1,573 US dollars (17%). Approximately 25% of patients received biologic therapy. The mean total annual direct cost for patients receiving biologic agents was 19,016 US dollars per year, while the cost for those not receiving biologic therapy was 6,164 US dollars. RA patients who were in the worst quartile of functional status, as measured by the Health Assessment Questionnaire, experienced direct medical costs for the subsequent year that were 5,022 US dollars more than the costs incurred by those in the best quartile. Physical status as determined by the Short Form 36 physical component scale had a similar large effect on RA costs, as did comorbidity. Medical insurance type played a more limited role. However, those without insurance had substantially lower service utilization and costs, and health maintenance organization patients had lower drug costs and total medical costs. Increased years of education, increased income, and majority ethnic status were all associated with increased drug costs but not hospitalization costs. Costs in all categories decreased after age 65 years. Conclusion Estimates of direct medical costs for patients with RA are substantially higher than cost estimates before the biologic therapy era, and costs are now driven predominantly by the cost of drugs, primarily biologic agents. RA patients with poor function continue to incur substantially higher costs, as do those with comorbid conditions, and sociodemographic characteristics also play an important role in determination of costs.

TL;DR: The authors found that epistemological beliefs tend to be domain independent (i.e., they generalize across domains) and most students showed a consistent level of epistemology sophistication across domains.
Abstract: Investigators of students' beliefs about the nature of knowledge and learning, or epistemological beliefs, have generally assumed that epistemological beliefs are domain independent (i.e., they generalize across domains). The purpose of this research is to test this assumption. College students completed an epistemological questionnaire with a specific domain in mind (either social sciences or mathematics), read a passage (either social sciences or mathematics), answered a passage test, and completed another epistemological questionnaire with the alternative domain in mind. Results supported the idea that individuals' epistemological beliefs tend to be domain independent. Mathematical epistemological factors correlated with the corresponding social science epistemological factors. Epistemological beliefs in both domains predicted passage comprehension similarly, and most students showed a consistent level of epistemological sophistication across domains.

TL;DR: The results show that at the post adoption stage, perceived IS usefulness is a good predictor of extended usage and exploratory usage, However, surprisingly IS usefulness was found to explain a much larger variance in exploratory used, and information quality and system integration were found to influence IS usefulness.
