Abstract

Climate change and permafrost thaw may impact the mobilization of terrestrial dissolved organic carbon (DOC), mercury (Hg), and neurotoxic methylmercury (MeHg) into aquatic ecosystems; thus, understanding processes that control analyte export in northern catchments is needed. We monitored water chemistry for 3 years (2019–2021) at a peatland catchment (Scotty Creek) and a mixed catchment (Smith Creek) in the Dehcho (Northwest Territories), within the discontinuous permafrost zone of boreal western Canada. The peatland catchment had higher DOC and dissolved MeHg, but lower total Hg concentrations (mean ± standard deviation; 19 ± 2.6 mg DOC L−1; 0.08 ± 0.04 ng DMeHg L−1; 1.1 ± 0.3 ng THg L−1) than the mixed catchment (12 ± 4.4 mg DOC L−1; 0.05 ± 0.01 ng DMeHg L−1; 3.1 ± 2.2 ng THg L−1). Analyte concentrations increased with discharge at the mixed catchment, suggesting transport limitation and the flushing of near‐surface, organic‐rich flow paths during wet periods. In contrast, analyte concentrations in the peatland catchment were not primarily associated with discharge. MeHg concentrations, MeHg:THg, and MeHg:DOC increased with water temperature, suggesting enhanced Hg methylation during warmer periods. Mean open water season DOC and total MeHg yields were greater and more variable from the peatland than the mixed catchment (1.1–6.6 vs. 1.4–2.4 g DOC m−2; 5.2–36 vs. 6.1–10 ng MeHg m−2). Crucial storage thresholds controlling runoff generation likely drove greater inter‐annual variability in analyte yields from the peatland catchment. Our results suggest climate change may influence the production and transport of MeHg from boreal‐Arctic catchments as temperatures increase, peatlands thaw, and runoff generation is altered. Plain Language Summary: Boreal rivers deliver dissolved organic carbon (DOC), mercury (Hg), and its neurotoxic form, methylmercury (MeHg), from contributing landscapes to downstream waters. In northern regions, thawing permafrost (i.e., perennially frozen ground) in peatland environments may release Hg, MeHg, and DOC from soils to rivers. Over 3 years, we measured the concentrations of water chemistry in two boreal creeks with differing contributing landscapes in the discontinuous permafrost region of the Dehcho (Northwest Territories, Canada). Our results showed different patterns in analyte concentrations versus yields (i.e., annual analyte mass delivered per unit area) between the sites. At the peatland‐dominated Scotty Creek, concentrations of MeHg and DOC were consistently high and not primarily controlled by discharge. Still, runoff and analyte yields varied annually as peatlands stored water in a dry year and discharged water in wet years. At Smith Creek, with a mixed landscape of mountains, peatlands, and forests, concentrations of DOC and Hg increased during high‐flow events as runoff contributions from peatlands increased. Over the monitoring period, analyte yields at the mixed catchment varied less due to consistent groundwater inputs and runoff generation from steeper slopes. Changing runoff due to climate change and permafrost thaw will likely alter analyte yields in the region. Key Points: Comparison of mercury, methylmercury, and dissolved organic carbon concentrations and yields for a peatland and a mixed‐landscape catchmentProduction of methylmercury in the peatland catchment was temperature‐dependent, and yields were limited by runoff generation thresholdsAnalyte concentrations in the mixed catchment increased with discharge, and had lower inter‐annual variability in analyte yields [ABSTRACT FROM AUTHOR]

Abstract

This research project benefitted from Ministry of Education (Singapore) Tier 1 Grant R-313-000-131-115 (to A. Delios), National Science Foundation of China Grants 72002158 (to H.T.) and 71810107002 (to H.T.), grants from the Knut and Alice Wallenberg Foundation (to A. Dreber) and the Marianne and Marcus Wallenberg Foundation (through a Wallenberg Scholar grant; to A. Dreber), Austrian Science Fund (FWF) Grant SFB F63 (to A. Dreber), grants from the Jan Wallander and Tom Hedelius Foundation (Svenska Handelsbankens Forskningsstiftelser; to A. Dreber), and an Research & Development (R&D) research grant from Institut Européen d'Administration des Affaires (INSEAD) (to E.L.U.). Dmitrii Dubrov, of the G.T.F.C., was supported by the National Research University Higher School of Economics (HSE University) Basic Research Program. This initiative examined systematically the extent to which a large set of archival research findings generalizes across contexts. We repeated the key analyses for 29 original strategic management effects in the same context (direct reproduction) as well as in 52 novel time periods and geographies; 45% of the reproductions returned results matching the original reports together with 55% of tests in different spans of years and 40% of tests in novel geographies. Some original findings were associated with multiple new tests. Reproducibility was the best predictor of generalizability—for the findings that proved directly reproducible, 84% emerged in other available time periods and 57% emerged in other geographies. Overall, only limited empirical evidence emerged for context sensitivity. In a forecasting survey, independent scientists were able to anticipate which effects would find support in tests in new samples. Publisher PDF

39. Patient Information Leaflets for Lumbar Spine Surgery: An Opportunity for Improvement of Enhanced Recovery Pathways

Author

Low, M., Burgess, Louise, and Wainwright, Tom

Abstract

Objectives: Enhanced Recovery after Surgery (ERAS) has recently been applied to lumbar spinal procedures, using evidence-based practice and improved pathways to encourage lower rates of morbidity and improve longer-term outcomes; however the evidence for adoption is limited. High quality patient information is recommended as part of ERAS pathways to attenuate procedure related anxiety. As increasing workload pressure continues to reduce the time clinicians have to spend with patients, patient information leaflets remain an invaluable resource to facilitate the retention of important health information. The aim of this study is to analyse the current quality of patient information leaflets given to patients ahead of lumbar spine surgery in English National Health Service (NHS) Hospitals. Methods: Patient information leaflets were sourced from the websites of NHS providers of lumbar spinal surgery. The quality of the leaflets was evaluated using the DISCERN tool, a standardized 16-item instrument designed to help the users of consumer health information judge the quality of the written information about treatment choices. Reviewers assigned each question a score on a five-point Likert scale (one for low quality with extensive shortcomings, five for a high quality with minimal short comings). Results: Thirty two patient information leaflets on lumbar surgery were sourced (fusion, n=11; decompression, n=15; all lumbar procedures, n=6). Two leaflets (6%) were considered poor, 13 (41%) were marked as fair, 14 (44%) were of good quality and three (9%) were scored as excellent. The total mean score was 55 (30-74) which corresponds to good quality. The lowest scoring questions were: sources of information (Q4), balanced/unbiased (Q6) and results of no treatment (Q12). Consistently high scoring questions were: date of publication (Q5), description of treatment (Q9) and quality of life (Q13). Conclusion: The rationale for needing high quality preoperative patient information is well-documented; however there is considerable variation in the quality of the leaflets provided ahead of lumbar spine surgery. The scope for improvement is clear, and as the move towards patient centred evidence-based care continues, it is important that hospital resources provide recommendations based upon shared decision making and evidence of clinical effectiveness.

Abstract

This paper describes an integrated alignment model towards Industry 4.0 for undergraduate engineering education. This integrated alignment model nurtures synergy among engineering education activities such as applied learning, applied research, and continuous education training (CET) programs to share a common Industry 4.0 vision. The stakeholders of this model include students, faculty, industry partners, and recipients of CET programs. This model applies Singapore Smart Industry Readiness Index (SIRI) as a guideline to align the various engineering activities. It advocates effective collaborations with industry partners, thus improve the quality of applied learning and applied research. Meanwhile, industry partners can benefit from receiving the state-of-the-art concepts and knowledge of Industry 4.0. The proposed integrated model provides practical guidelines to align the undergraduate engineering education towards Industry 4.0 vision. The case study presented in this paper shows that multifaceted results can be obtained from applying this model. [ABSTRACT FROM AUTHOR]
