Asymmetric effects of oil price shocks on the demand for money in Algeria by Amirouche, Chelghoum

“…This paper investigates the symmetric and asymmetric effects of real oil prices on real money demand in Algeria over the period 1999:Q1–2020:Q1. Using a linear autoregressive distributed lag model (ARDL), and a nonlinear autoregressive distributed lag model (NARDL), we find no evidence of a long-term relationship among the variables. …”

Rebound effects undermine carbon footprint reduction potential of autonomous electric vehicles by Onat, Nuri C.

“…In this study, we investigate tradeoffs between improved fuel economy and rebound effects from a life-cycle perspective. Our results show that autonomy introduces an average 21.2% decrease in operation phase emissions due to improved fuel economy while manufacturing phase emissions can surge up to 40%. …”

Pharmacoeconomic evaluation of voriconazole vs. liposomal amphotericin B in empiric treatment of invasive fungal infections in Turkey by Turner, Stuart J.

“…Univariate sensitivity analysis highlighted that increasing the duration of voriconazole by >1.2 days or decreasing LAmB by >1.0 days changes the result. Monte Carlo Simulation resulted in 69.4% of simulations favouring voriconazole per patient treated.Conclusion: There is a strong likelihood that voriconazole is economically more favourable than LAmB in the empiric treatment of IFI in Turkey.…”

Effect of Verbal Encouragement on Performance and Affective Responses in Male Sport Science Students during Sprint Modalities by Sahli, Faten

“…The assessed parameters comprised physical performance, rating of perceived exertion (RPE), and a feeling scale. Post hoc test analysis indicates a significant increase in physical performance during VETS and VESS conditions compared to the control condition due to a decrease in sprint in line 20 m (VETS: p < 0.001, d = 0.55; VESS: p = 0.016, d = 0.41), sprint 10*2 (VETS: p < 0.001, d = 0.64; VESS: p = 0.05, d = 0.36), and sprint L (VETS: p = 0.001, d = 1.19) times compared to the control condition. …”

Unraveling the future productivity burden of cardiovascular disease in Qatar: Investigating the modifiable risk factors control in type 2 diabetes by Abushanab, Dina

“…The financial value of PALYs was determined based on the gross domestic product (GDP) per full-time worker (i.e. US$80,573). The base-case model estimated the productivity burden of CVD, and interventional scenarios were simulated to assess potential gains resulting from improved control of modifiable risk factors, including reduced incidence of T2D, lower systolic blood pressure (SBP), decreased number of smokers, and reduced total cholesterol. …”
