Neural Correlates of Causal Confounding
Authors: Liljeholm Mimi 
Published: October 2019

Abstract
As scientists, we are keenly aware that if putative causes perfectly covary, the independent influence of neither can be discerned—a “no confounding” constraint on inference, fundamental to philosophical and statistical perspectives on causation. Intriguingly, a substantial behavioral literature suggests that naïve human reasoners, adults and children, are tacitly sensitive to causal confounding. Here, a combination of fMRI and computational cognitive modeling was used to investigate neural substrates mediating such sensitivity. While being scanned, participants observed and judged the influences of various putative causes with confounded or nonconfounded, deterministic or stochastic, influences. During judgments requiring generalization of causal knowledge from a feedback-based learning context to a transfer probe, activity in the dorsomedial pFC was better accounted for by a Bayesian causal model, sensitive to both confounding and stochasticity, than a purely error-driven algorithm, sensitive only to stochasticity. Implications for the detection and estimation of distinct forms of uncertainty, and for a neural mediation of domain-general constraints on causal induction, are discussed.
The Role of Free-Stream Turbulence in Attenuating the Wind Updraft above the Collector of Precipitation Gauges

Published: October 2019

AbstractIn operational conditions, wind is the main environmental source of measurement biases for catching-type precipitation gauges. The gauge geometry induces a deformation of the surrounding airflow pattern, which is generally characterized by relevant updraft zones in front of the collector and above it. This effect deviates the trajectories of the lighter hydrometeors away from the collector and thus is responsible for a significant reduction of the collection performance. Previous approaches to this problem, using computational fluid dynamics simulations and wind-tunnel tests, mostly assumed steady and uniform free-stream conditions. Wind is turbulent in nature, though. The role of natural free-stream turbulence on collection performance is investigated in this work for the case study of a calyx-shaped precipitation gauge and wind velocity between 10 and 18 m s−1. The unsteady Reynolds-averaged Navier–Stokes model was adopted. Turbulent conditions were simulated by imposing constant free-stream velocity and introducing a fixed solid fence upstream of the gauge to generate the desired turbulence intensity. Wind-tunnel measurements allowed validating numerical results by comparing measured and simulated velocity profiles in representative portions of the investigated domain. Results revealed that in the case of turbulent free-stream conditions both the normalized magnitude of the flow velocity and the updraft above the collector are reduced by approximately 20% and 12%, respectively. The dissipative effect of the turbulent fluctuations in the free stream has a damping role on the acceleration of the flow and on the updraft. This would result in a reduced undercatch with respect to literature simulations that employed the traditional uniform free-stream conditions.
The Extratropical Transition of Hurricane Debby (1982) and the Subsequent Development of an Intense Windstorm over Finland

Abstract
On 22 September 1982, an intense windstorm caused considerable damage in northern Finland. Local forecasters noted that this windstorm potentially was related to Hurricane Debby, a category 4 hurricane that occurred just 5 days earlier. Due to the unique nature of the event and lack of prior research, our aim is to document the synoptic sequence of events related to this storm using ERA-Interim reanalysis data, best track data, and output from OpenIFS simulations. During extratropical transition, the outflow from Debby resulted in a ridge building and an acceleration of the jet. Debby did not reintensify immediately in the midlatitudes despite the presence of an upper-level trough. Instead, ex-Debby propagated rapidly across the Atlantic as a diabatic Rossby wave–like feature. Simultaneously, an upper-level trough approached from the northeast and once ex-Debby moved ahead of this feature near the United Kingdom, rapid reintensification began. All OpenIFS forecasts diverged from reanalysis after only 2 days indicating intrinsic low predictability and strong sensitivities. Phasing between Hurricane Debby and the weak trough, and phasing of the upper- and lower-level potential vorticity anomalies near the United Kingdom was important in the evolution of ex-Debby. In the only OpenIFS simulation to correctly capture the phasing over the United Kingdom, stronger wind gusts were simulated over northern Finland than in any other simulation. Turbulent mixing behind the cold front, and convectively driven downdrafts in the warm sector, enhanced the wind gusts over Finland. To further improve understanding of this case, we suggest conducting research using an ensemble approach.

Published: October 2019

Background Measurement of serum neuron-specific enolase (NSE) for neuro-prognostication post out-of-hospital cardiac arrest (OHCA) is recommended by international guidelines. There is, however, a lack of consensus regarding the cut-offs and time points to use. In addition, NSE is particularly susceptible to haemolysis interference. This study aimed to define the optimum NSE testing strategy to support the intensive care unit (ICU). Methods Patients admitted to ICU post-OHCA over 16 months had NSE measured. The outcome was survival to ICU discharge. NSE at 0 h, 24 h, 48 h, 72 h and change in NSE (ΔNSE) were assessed for prognostic accuracy using receiver operator characteristic curve analysis. The magnitude of haemolysis interference was quantified by spiking haemolysate into paired serum. Results There is a consistent linear increase in NSE with increasing haemolysis, independent of baseline NSE concentration. A haemolysis index acceptance threshold was defined as 20. There were 142 patients, and 82 survived to ICU discharge. The NSE parameter with best predictive performance was ΔNSE at 48 h, which had an area under the receiver operator characteristic curve of 0.91. A cut-off of >0 μg/L at this time point had sensitivity of 80% and specificity of 97% for predicting death on ICU. When patients who died of non-neurological causes were removed, the sensitivity increased to 91%. Conclusions Application of a stringent haemolysis interference threshold and measurement of NSE at two time points enabled us to achieve excellent discrimination. Increasing NSE over the first 48 h, suggestive of an ongoing reperfusion injury to the brain, is a strong predictor of poor outcome.
Public–private partnerships: procedural over results-driven accountability
Authors: Parrado Salvador , Reynaers Anne-Marie 
Published: October 2019

The article examines to what extent Dutch and Spanish officials make trade-offs between process and result accountability during the design, management and adaptation of contracts for public–private partnerships. The countries’ distinct administrative traditions (legalistic versus managerial-oriented, respectively) are expected to be influential. Analysing contracts, policy documents and interviews with 89 Dutch and Spanish project members, the article shows that Dutch administrators focus on outcome accountability, following the tenets of relational governance, whereas Spanish officials opt for process accountability in line with the contractual governance framework in non-clinical services, and for result accountability for clinical services in hospitals. Points for practitioners • Procedural and results-based accountability are not necessarily alternatives. High legalistic countries may emphasize process accountability but results-based accountability is needed to realize the potential from the private-sector operator delivering public services. • Long-term contracts require that the procurer first sets the results to be achieved and then work out the more suitable accountability mechanisms. • Results-based accountability requires competencies that are not easily found in the public sector of legalistic countries and this is key for properly giving account of the contract.

Published: October 2019

The integration of photovoltaic modules into the building structure is a challenging task with respect to power generation of PV module and the effect of incident solar radiation. The performance of building integrated photovoltaic (BIPV) modules varies depending upon the orientation and azimuth angle of the building. In this work, the year-round performance and economic feasibility analysis of grid-connected building-integrated photovoltaic (GBIPV) modules is reported for the hot and humid climatic regional condition at Kovilpatti (9°10′0′′N, 77°52′0′′E), Tamil Nadu, India. The appropriate mounting structures are provided, to experimentally simulate the performance of GBIPV modules at various orientations and inclination angles (0° to 90°). The result indicated that the optimum orientation for installation of BIPV modules in the façade and walls is found to be east while that for a pitched roof south orientation is recommended. The overall average annual performance ratio, capacity utilisation factor, array capture loss and system losses are found to be 0.83, 23%, 0.07 (h/day), and 0.17 (h/day), respectively. In addition, the economic feasibility of grid connected PV system for residential buildings in Tamil Nadu, India is analysed using HOMER by incorporating both a net metering process and electricity tariff. Practical application: Grid-connected building-integrated photovoltaic system has many benefits and barriers by being installed and integrated into the building structure. The application of GBIPV in building structures and its orientation of installation needs to be optimised before installing into buildings. This study will assist architects and wider community to design buildings facades and roofs with GBIPV system which are more aesthetic and account for noise protection and thermal insulation in the region of equatorial climate zones. By adding as shading devices, they can reduce the need for artificial lighting, and moderate heating or cooling load of the buildings.

Published: October 2019

Purpose The purpose of the study was to examine feasibility outcomes and obtain initial efficacy data on an intervention testing collaborative implementation intentions (IIs) for physical activity (PA) among participants with type 2 diabetes. Methods The study used a pilot randomized design and enrolled people with diabetes (PWD) and their partners (N = 40 couples, 80 individuals). PWD reported psychosocial measures, including self-efficacy for PA, diabetes partner investment in diabetes self-management, and PA-related social support. Accelerometers (objective) and the International Physical Activity Questionnaire (self-report) were used to assess PA. Results Participants in both experimental conditions reported being satisfied with the intervention and highly committed to their PA plans. Participants were able to follow instructions and completed the intervention in less than 30 minutes. Participants in the collaborative IIs condition reported a greater increase in PA-related social support (partial 2 = .185, P < .05) and self-reported recreational PA (partial 2 = .210, P < .05) at 6 weeks compared to the other 2 conditions. In this pilot study, there were no significant group differences on other psychosocial outcomes or for objective PA; however, time in light PA trended higher for the collaborative IIs condition compared to the other 2 conditions (partial 2 = .237, P = .056). Conclusions This study provides initial support for collaborative IIs for PA with PWD and their partners. This brief intervention was feasible and highly acceptable, and it may improve relationship dynamics around PA as well as ultimately increase PA.

Authors: Godlwana Lonwabo , Stewart Aimee , Musenge Eustasius 
Published: October 2019

Objective: To establish if a home-based exercise and education programme is more effective than usual treatment in improving function, mobility and quality of life in people with lower limb amputation due to peripheral vascular disease. Method: A blocked randomized single-blinded controlled trial (RCT) with 154 participants (54 female; mean age 58) compared a home-based exercise and education programme (n = 77) with usual care (control) (n = 77). Participants were measured at baseline, immediately post intervention at three months, and after a further three months without any intervention. The outcome measures were the Barthel Index, Participation Scale, EuroQuol 5D, Modified Locomotor Capability Index and Timed Up and Go Test. Changes over time were established using generalized estimating equations and analysis of covariance, ( P < 0.05) Results: The Participation Scale (18.73 ± 14.91 against 26.67 ± 19.14; P = 0.011), the EuroQuol5D visual analogue scale (69.10 ± 20.31 against 55.37 ± 27.67; P = 0.003), EuroQuol5D utility index (0.672 ± 0.300 against 0.532 ± 0.358; P = 0.25) and the Modified Capability Index (21.03 ± 15.79 against 15.91 ± 13.67; P = 0.034) improved in the intervention group compared with the control group at three months. At six months, there was no difference between the groups in any of the measures except for the EuroQuol5D visual analogue scale (74.52 ± 16.14 against 66.34 ± 22.91; P = 0.033). Although there were no differences between the Timed Up and Go test at 3 (35.39 ± 32.48 against 45.08 ± 41.52; P = 0.192) and six months (28.22 ± 20.96 against 36.08 ± 36.19; P = 0.189) between the groups the intervention group was more mobile. Conclusion: This intervention improved function, mobility and quality of life in persons following lower limb amputation in the first three months post amputation.

Published: October 2019

Background: Posterior glenoid bone deficiency is an increasingly recognized entity in the setting of recurrent posterior shoulder instability; however, little is known about the subject. Due to the paucity of literature on posterior bone loss, historical comparisons with anterior bone loss may not be fully accurate. Purpose: To systematically describe the morphology of posterior bone defects in the setting of recurrent posterior shoulder instability based on several quantitative parameters, including the mean location, orientation, and extent of bone loss on a clockface model, as well as the angle of the defect relative to the long axis of the glenoid. Study Design: Cross-sectional study; Level of evidence, 4. Methods: Three-dimensional reconstructed computed tomography scans of serially collected patients with a history of recurrent posterior shoulder instability were evaluated by 3 separate reviewers. The posterior glenoid bone defect was characterized using the following measures: (1) the mean lesion location and orientation based on a clockface model with 6 o’clock denoted as inferior and 9 o’clock as directly posterior for all patients; (2) the total extent of the posterior bone defect based on the clockface; and (3) the average angle of the bone loss relative to the long axis of the glenoid. Results: A total of 70 male patients and 1 female patient with a mean age of 29.3 years (range, 24.4-35.1 years) were included in the analysis. The mean clockface location of the posterior glenoid defect originated at 6:44 (range, 4:16-8:12) and extended to a mean of 9:28 (range, 7:02-10:38). The mean extent of the posterior glenoid defect was 2:43 (range, 1:08-4:50), which corresponds to a mean total bone loss arc of 81.5° (range, 34.2°-144.9°), nearly 1 quadrant of the glenoid. Posterior bone loss occurred in a posteroinferior direction at a mean angle of 30.7° (range, 8.0°-80.0°) relative to the long axis of the glenoid. Conclusion: Posterior bone defects in the setting of posterior shoulder instability most commonly occur in the posteroinferior quadrant of the glenoid and extend on average from 6:44 to 9:28 (81.5° total degrees of arc) on a clockface model. Posterior bone loss occurs at a mean of 30° off the long axis of the glenoid in a posteroinferior direction, which is historically different from anterior bone loss, which occurs parallel to the long axis of the glenoid. This study serves to highlight the location and orientation of bone loss that one can expect in a patient with recurrent posterior shoulder instability, although additional work is needed to assess why this develops.
Global Patterns of Adolescent Fruit, Vegetable, Carbonated Soft Drink, and Fast-Food Consumption: A Meta-Analysis of Global School-Based Student Health Surveys
Authors: Beal Ty , Morris Saul S. , Tumilowicz Alison 
Published: October 2019

Background: Adolescence presents an opportunity to influence diet, which impacts present and future health outcomes, yet adolescent diets globally are poorly understood. Objective: We generate evidence on adolescent diets globally and explore patterns and trends by subpopulation. Methods: We estimated mean frequency of consumption and prevalence of less-than-daily fruit and vegetable consumption, at-least-daily carbonated beverage consumption, and at-least-weekly fast-food consumption among school-going adolescents aged primarily 12 to 17 years from the Global School-based Student Health Surveys in Africa, Asia, Oceania, and Latin America between 2008 and 2015. Random-effects meta-analysis was used to pool estimates globally and by subgroup. Results: On average, adolescents consumed fruit 1.43 (95% confidence interval [CI] 1.26–1.60) times per day, vegetables 1.75 (1.58–1.92) times per day, carbonated soft drinks 0.99 (0.77–1.22) times per day, and fast food 1.05 (0.78–1.32) times per week. Overall, 34.5% (95% CI 29.4–39.7) consumed fruit less than once per day, 20.6% (15.8–25.9) consumed vegetables less than once per day, 42.8% (35.2–50.7) drank carbonated soft drinks at least once per day, and 46.1% (38.6–53.7) consumed fast food at least once per week. Mean daily frequency of fruit consumption was particularly low in South and East Asia (1.30 [1.02–1.58]); carbonated soft drink consumption high in Latin America (1.54 [1.31–1.78]), high-income countries (1.66 [1.29–2.03]), and modern food system typologies (1.44 [0.75–2.12]); and mean weekly fast food consumption high in mixed food system typologies (1.29 [0.88–1.71]). Conclusions: School-going adolescents infrequently consume fruits and vegetables and frequently consume carbonated soft drinks, but there is wide variability by subpopulation.
Access to Firearms Among People Assessed by Psychiatric Services in the Emergency Department
Authors: Katz Cara , Bhaskaran Joanna , Bolton James M. 
Published: October 2019

Objective: In Canada, 80% of firearm-related deaths are suicides. Access to firearms is associated with increased suicide rates. This study examines the frequency and factors that influence assessment of firearm access in an emergency setting. Methods: A total of 15,847 consecutive adults seen for psychiatric consultation in two tertiary emergency departments (EDs) in Winnipeg, Manitoba were interviewed. Data captured whether access to firearms was assessed, and whether respondents endorsed access or not. Comparisons were done to determine group differences among those with and without and with known and unknown firearm access. Results: Access to firearms was unknown in 47% ( n = 7,363) of psychiatric ED consultations, including 43% ( n = 998) of individuals who presented with a suicide attempt. Female sex was associated with decreased odds of firearm access (odds ratio [ OR] 0.28; 95% CI, 0.22 to 0.35). Being single was associated with lower odds of known firearm access ( OR 0.83; 95% CI, 0.77 to 0.89) yet higher likelihood of firearm access ( OR 1.36; 95% CI, 1.11 to 1.68). Presenting with a suicide attempt ( OR 2.45; 95% CI, 1.80 to 3.34), preparatory acts ( OR 6.40; 95% CI, 4.38 to 9.36) and suicidal ideation ( OR 2.45; 95% CI, 1.87 to 3.21) were associated with increased odds of reporting access. When clinicians felt there was a high likelihood of future suicide, firearm access remained unknown in half of cases. Conclusion: Firearm ownership and access is an essential component of a suicide risk assessment and remains unknown in half of individuals seen by psychiatry in this tertiary care ED sample. People presenting with suicidal ideation and attempts were more likely to report access to firearms.
A Short History of Table-Talk and Live-Action Role-Playing in Japan: Replays and the Horror Genre as Drivers of Popularity
Authors: Kamm Björn-Ole 
Published: October 2019

Background. The history of larp, live-action role-play, in Japan may be rather short but documents exponential growth in the entertainment sector as well as in educational gaming. Following trends of related forms of analog role-playing games, the horror genre functions as a motor of increasing popularity. Aim. This article explores the development of non-digital role-playing games in the Japanese context in light of the online video platform niconico popularizing horror role-playing and practical considerations of adopting the genre to live-action play. Method. Cyberethnographic fieldwork including participant observation at larps between 2015 and 2018 forms the data basis for this article, followed by qualitative interviews with larp organizers, larp writers, and designers of analog games as well as observations online in respective webforums. Results. Replays, novelized transcripts of play sessions, have been an entry point into analog role-playing in Japan since the 1980s. With the advent of video sharing sites, replays moved from the book to audio-visual records and a focus on horror games. Creating a fertile ground for this genre, the first indigenous Japanese larp rulebook built on this interest and the ease of access, namely that players do not need elaborate costumes or equipment to participate in modern horror. Discussion. The dominant form of larps in Japan are one-room games, that work well with horror mysteries and function as a low threshold of accessibility. Furthermore, the emotional impact of horror larps, the affective interaction between players and their characters, allows for memorable experiences and so continues to draw in new players and organizers.
