TL;DR: The study found an inverted U-shaped pattern between energy use and economic growth in the long run, suggesting that at a higher level of economic development there is less intensification of energy consumption, hence, signifying a decline in energy intensity while validating energy efficiency in South Africa.

TL;DR: There is a high rate of acute PCS in both mTBI and non-brain injured trauma patients, and the use of the term PCS may be misleading as it incorrectly suggests that the basis of PCS is a brain injury.
Abstract: Background: The aetiology of postconcussion syndrome (PCS) following mild traumatic brain injury (mTBI) remains controversial. Identifying acute PCS (within the first 14 days after injury) may optimise initial recovery and rehabilitation, identify those at risk and increase understanding of PCS. Objective: To examine predictors of acute outcome by investigating the relationship between preinjury psychiatric disorder, demographic factors, injury related characteristics, neuropsychological and psychological variables and acute PCS. Methods: Prospective study of consecutive trauma admissions to a level 1 trauma hospital. The final sample comprised 90 patients with mTBI and 85 non-brain injured trauma controls. Individuals were administered a PCS checklist, and neuropsychological and psychological measures. Multiple imputation of missing data in multivariable logistic regression and bivariate logistic regressions were used to predict acute PCS at a mean of 4.90 days after injury. Results: Diagnosis of acute PCS was not specific to mTBI (mTBI 43.3%; controls 43.5%). Pain was associated with acute PCS in mTBI. The strongest effect for acute PCS was a previous affective or anxiety disorder (OR 5.76, 95% CI 2.19 to 15.0). Females were 3.33 times more likely than males to have acute PCS (95% CI 1.20 to 9.21). The effect of acute post-traumatic stress and neuropsychological function on acute PCS was relatively small. Higher IQ was associated with acute PCS. Conclusions: There is a high rate of acute PCS in both mTBI and non-brain injured trauma patients. PCS was not found to be specific to mTBI. The use of the term PCS may be misleading as it incorrectly suggests that the basis of PCS is a brain injury.

TL;DR: In this article, the authors used the statistics for halo concentration parameters in large cosmological simulations as a constraint to estimate the escape speed of the Milky Way-sized galaxies.
Abstract: We made new estimates of the Galactic escape speed at various Galactocentric radii using the latest data release of the RAdial Velocity Experiment (RAVE DR4) Compared to previous studies we have a database that is larger by a factor of 10, as well as reliable distance estimates for almost all stars Our analysis is based on statistical analysis of a rigorously selected sample of 90 highvelocity halo stars from RAVE and a previously published data set We calibrated and extensively tested our method using a suite of cosmological simulations of the formation of Milky Way-sized galaxies Our best estimate of the local Galactic escape speed, which we define as the minimum speed required to reach three virial radii R340, is 533 +54 −41 km s −1 (90% confidence), with an additional 4% systematic uncertainty, where R340 is the Galactocentric radius encompassing a mean overdensity of 340 times the critical density for closure in the Universe From the escape speed we further derived estimates of the mass of the Galaxy using a simple mass model with two options for the mass profile of the dark matter halo: an unaltered and an adiabatically contracted Navarro, Frenk & White (NFW) sphere If we fix the local circular velocity, the latter profile yields a significantly higher mass than the uncontracted halo, but if we instead use the statistics for halo concentration parameters in large cosmological simulations as a constraint, we find very similar masses for both models Our best estimate for M340, the mass interior to R340 (dark matter and baryons), is 13 +04 −03 × 10 12 M� (corresponds to M200 = 16 +05 −04 × 10 12 M� ) This estimate is in good agreement with recently published, independent mass estimates based on the kinematics of more distant halo stars and the satellite galaxy LeoI

TL;DR: The new self- guided course was beneficial, and automated emails facilitated outcomes, and further attention to strategies that facilitate adherence, learning, and safety will help realise the potential of self-guided interventions.
Abstract: Background Depression and anxiety are common, disabling and chronic Self-guided internet-delivered treatments are popular, but few people complete them New strategies are required to realise their potential Aims To evaluate the effect of automated emails on the effectiveness, safety, and acceptability of a new automated transdiagnostic self-guided internet-delivered treatment, the Wellbeing Course, for people with depression and anxiety Method A randomised controlled trial was conducted through the website: wwwecentreclinicorg Two hundred and fifty seven people with elevated symptoms were randomly allocated to the 8 week course either with or without automated emails, or to a waitlist control group Primary outcome measures were the Patient Health Questionnaire 9-Item (PHQ-9) and the Generalized Anxiety Disorder 7-Item (GAD-7) Results Participants in the treatment groups had lower PHQ-9 and GAD-7 scores at post-treatment than controls Automated emails increased rates of course completion (58% vs 35%), and improved outcomes in a subsample with elevated symptoms Conclusions The new self-guided course was beneficial, and automated emails facilitated outcomes Further attention to strategies that facilitate adherence, learning, and safety will help realise the potential of self-guided interventions Trial Registration Australian and New Zealand Clinical Trials Registry ACTRN12610001058066
