International youth mental health case study of peer researchers’ experiences

BACKGROUND: The involvement of young people as peer researchers, especially with lived experience, is increasingly considered important in youth mental health research. Yet, there is variation in the understanding of the role, and limited evidence on its implementation across different research systems. This case study focusses on the barriers and enablers of implementing peer researcher roles within and across majority world countries contexts. METHODS: Based on an international youth mental health project involving different levels of peer researchers and participants from eight countries, peer researchers and a co-ordinating career researcher reflect on lessons regarding enabling and challenging factors. These reflections are captured and integrated by a systematic insight analysis process. RESULTS: Building on existing international networks, it was feasible to actively involve peer researchers with lived experience in a multi-country mental health study, who in turn recruited and engaged young participants. Identified challenges include the terminology and definition of the role, cultural differences in mental health concepts, and consistency across countries and sites. DISCUSSION: Peer researchers’ role could be strengthened and mainstreamed in the future through ongoing international networks, training, sufficient planning, and active influence throughout the research process.

Proceedings: 3rd International Conference on Food and Agricultural Economics: THE IMPACT OF EXCHANGE RATE VOLATILITY ON TURKEY’S LIVESTOCK IMPORTS

Turkey is a country with high young population rate. Also, after the internal conflicts that arose in neighboring countries, flocks of people have immigrated to Turkey. High population growth caused high food demand. Also, most of the population in Turkey is Muslim, and it is creating extra demand in the feast of sacrifice. During recent years, because of these reasons, the supply of meat could not meet the demand, and high demand increased the meat prices with high costs. The government of Turkey, therefore, started to import live animals to reduce meat prices. In this study, for the period 2005M01- 2018M01, the relationship between real effective exchange rate, real effective exchange rate volatility and Turkey’s livestock imports was examined using bounds test, symmetric and timevarying symmetric causality tests. In this study, unit root analysis was performed using ADF and PP tests. The results of ADF and PP unit root tests indicated that the parameters were stationary at different levels and that none of the parameters was stationary at the 2nd level. According to bounds test, the F-statistic value calculated at a significant level of 5% and 10% was found less than bottom limits, the cointegration relation between the variables was not determined. As a result of the bounds test, it was concluded that there was no long-term relationship between the variables. According to the results of a Hacker-Hatemi-J causality test, a causality relationship was not found from volatility, reel effective exchange rate and industrial production index to Turkey’s livestock exports. Timer varying causality analysis confirmed this result for a significant part of the time interval. However, a causality relationship was determined for some periods from volatility, reel effective exchange rate and industrial production index to Turkey’s livestock exports. In this study,for the period 2005M01- 2018M01, the relationship between real effective exchange rate, real effective exchange rate volatility and Turkey’s livestock imports was examined using bounds test, symmetric and time-varying symmetric causality tests

Parallel implicit DNS of temporally-evolving turbulent shear layer instability

In this study, a temporally-evolving incompressible and compressible Turbulent Shear Layer (TSL) instability problem is solved using an all-speed (all-Mach), implicit, non-dissipative and kinetic energy conserving algorithm. An in-house, fully parallel, finite-volume Direct Numerical Simulation (DNS) solver was developed using PETSc. Convergence characteristics at low-Mach numbers were also improved using a relaxation procedure. We aim here to assess the performance and behavior of the present algorithm for complex flows which contain multi-scale physics and gradually evolve into turbulence. The results show that the algorithm is able to produce correct physical mechanisms and capture the evolution of the turbulent fluctuations for both incompressible and compressible cases. It is observed that the non-dissipative and kinetic energy conserving properties make the algorithm powerful and applicable to challenging problems. For higher Mach numbers, a shock-capturing or a dissipative mechanism is required for robustness. \ua9 2013 Elsevier B.V. All rights reserved

Application of a parallel solver to the LES modelling of turbulent buoyant flows with heat transfer

An existing fully implicit, non-dissipative direct numerical simulation (DNS) algorithm is reformulated to utilise the sub-grid scale (SGS) models in large eddy simulation (LES). The Favre-filtered equations with low-Mach number scaling are derived. The wall-adapting local eddy-viscosity (WALE) is used as SGS model. A fully parallel, finite volume solver is developed based on the resulting LES algorithm using PETSc library and applied to buoyancy- and thermally-driven transitional/turbulent flows in Rayleigh-Taylor instability and turbulent Rayleigh-B\ue9nard convection. Results verify that the proposed low-Mach number LES approach, which is physically more accurate than pure incompressible methods for flows with variable properties, perfectly captures the evolution and complex physics of turbulent buoyant flows with or without heat transfer by taking the effects of density and viscosity changes into account without the Oberbeck-boussinesq (OB) assumption even at large temperature differences with uniform accuracy and efficiency
