title: How initial conditions-, structural-, and parameter-based model uncertainty interact and influence predictions in permafrost ecosystems: Modeling Archive

description: This dataset contains model output and input data, as well as source code examples for the Terrestrial Ecosystem Model with the Dynamic Vegetation Model and Dynamic Organic Soil (DVM-DOS-TEM) for the field sites Imnavait creek and the Bonanza creek Long Term Ecological Research Network (LTER). The data covers simulations from the last glacial maximum (LGM) until 2100 for a selection of paleo scenarios, setting the mean temperature of the LGM up to 10°C lower than pre-industrial conditions. The model structure was modulated to represent various model versions, and this dataset contains the relevant changes in the source code. The raw output data, the processed statistical data, the setup and processing scripts as well as parameter value distribution files from a parameter sensitivity analysis are included as well. Model outputs include active layer depth, organic soil carbon, soil layer depths, gross primary productivity (GPP) with and without nitrogen limitation, net primary productivity (NPP), soil liquid water content, heterotrophic, maintenance, and growth respiration, soil temperature, and vegetation carbon (*.nc files). The Next-Generation Ecosystem Experiments in the Arctic (NGEE Arctic) project is a research effort to reduce uncertainty in the Department of Energy’s Energy Exascale Earth System Model (E3SM) by developing a predictive understanding of Arctic tundra ecosystems underlain by permafrost and to quantify feedbacks from the Arctic tundra to the Earth system. NGEE Arctic is supported by the Department of Energy's Office of Biological and Environmental Research.Over Phases 1–3, observations made by the NGEE Arctic team across a gradient of permafrost landscapes in Arctic Alaska improved the representation of tundra processes in the land surface component of E3SM (the E3SM Land Model, ELM). Model improvements emphasized unique aspects of permafrost environments and explored reductions in model complexity while retaining predictive power. The Arctic-informed ELM developed by NGEE Arctic has been used to make novel predictions on processes ranging from permafrost thaw to soil biogeochemical cycling to Earth system feedbacks associated with the unique characteristics of tundra plants. In Phase 4, the NGEE Arctic team is evaluating our new predictive understanding under novel conditions across the Arctic domain. In collaboration with partners at long-term pan-Arctic research sites we are examining whether an Arctic-informed ELM can faithfully simulate interactions among surface and subsurface processes at site, regional, and pan-Arctic scales. In turn, we are using variety of tools to dynamically extend and evaluate ELM inference, with an emphasis on data synthesis and pan-Arctic model evaluation, reintegration of code with an evolving E3SM, scaling across heterogeneous Arctic landscapes, and the appropriate representation of the impacts of increasingly frequent Arctic disturbances.

title: Endgame policy support survey panel data

description: The dataset consists of quantitative and qualitative data collected through an online survey administered to adults residing in the United States. The survey includes measures of support for 36 tobacco Endgame policies grouped into six categories: Direct Sales Restrictions, Retailer Location and Density Policies, Product Placement and Packaging Policies, Pricing and Nicotine Level Policies, Smokefree and Multiunit Housing Policies, and Eliminating Penalties for Underage Use. Each item used a six-point scale ranging from strong opposition to strong support. 

Demographic variables include age, sex, race and ethnicity, household income, educational level, employment status, and rural or urban residence. Behavioral variables record smoking frequency, e-cigarette use frequency, and overall tobacco use. Political affiliation is self-reported. The dataset also contains responses to a question about whether regulation of tobacco products should occur at the local, state, or federal level.

Only the raw data and not any recoded or composite scores are included in the dataset.

Open-ended responses explaining participants’ preferred level of government are included as a qualitative dataset. These responses were analyzed using thematic analysis; however, the raw text data are preserved and available for re-analysis. No identifying information is included.

Data were collected using an online survey platform (Qualtrics). Quality checks incorporated attention check items, minimum completion time thresholds, and removal of invalid responses. Zip codes were converted to rural or urban classifications using established publicly available geographic coding systems.

title: Replication Data for: Trial of High-Dose Oral Rifampin in Adults with Tuberculous Meningitis

description: Abstract: 

Background: Tuberculous meningitis is often lethal, and many survivors suffer from disabilities despite antimicrobial treatment and adjunctive glucocorticoid therapy. Standard-dose rifampicin has limited central nervous system penetration. Whether higher-dose rifampicin could improve survival outcomes is unknown.
 
Methods: We performed a double-blind, randomized, placebo-controlled clinical trial involving adults with tuberculous meningitis in Indonesia, South Africa and Uganda. We assigned persons with and those without human immunodeficiency virus (HIV) coinfection to receive standard daily isoniazid, rifampin (at a dose of 10 mg per kilogram of body weight), ethambutol, and pyrazinamide plus either additional rifampin (for a cumulative dose of 35 mg per kilogram; high-dose group) or matched placebo (standard-dose group) for 8 weeks. The primary outcome was 6-month survival.

Results: A total of 499 participants were included in the intention-to-treat population
(249 randomly assigned to the high-dose group and 250 to the standard-dose group), of whom 304 (60.9%) were persons living with HIV and 428 (85.8%) had definite or probable tuberculous meningitis. During 6 months of follow-up, 109 participants (Kaplan–Meier estimate, 44.6%) in the high-dose group and 100 participants (Kaplan–Meier estimate, 40.7%) in the standard-dose group died (hazard ratio, 1.17; 95% confidence interval, 0.89 to 1.54; P=0.25). Among the participants who died within 6 months, the median time to death was 13 days (interquartile range, 4 to 39) in the high-dose group and 24 days (interquartile range, 6 to 56) in the standard-dose group. Drug-induced liver injury occurred in 8.0% of the participants in the high-dose group and in 4.4% of those in the standard-dose group, but no deaths from drug-induced liver injury occurred.

Conclusions: Among persons with tuberculous meningitis, no evidence of beneficial effect from high-dose rifampin was observed, and the potential for a harmful effect cannot be ruled out. (Funded by the U.K. Medical Research Council and others; ISRCTN Registry number, ISRCTN15668391.)
