Issue 15: Economic Precarity among Syrian Refugee Families Living in Lebanon: Policy Recommendations to Restore Hope in the Context of Displacement

The conflict in Syria has been described as the largest humanitarian crisis to date. Ongoing for over eight years, the conflict has resulted in over five million refugees and 6.6 million people internally displaced within the borders of Syria. Most refugees from Syria have been displaced to neighbouring countries such as Jordan, Turkey, Iraq, and Lebanon. Lebanon is host to over one million Syrian refugees. Prior to the Syrian crisis, Lebanon was struggling economically, which has since exacerbated anti-refugee sentiment and government policies that aim to discourage Syrians from seeking refuge in Lebanon. Within Lebanon, Syrian families are challenged with high rates of poverty, restrictive governmental policies and regulations, a lack of affordable housing and health care, food insecurity, and family violence. These challenges have a destabilizing effect on Syrian families, impacting the mental health of parents as well as their ability to meet their families’ basic needs. This policy brief draws on research conducted with Syrian families in Lebanon to highlight policy points to address the impacts of economic precarity on the health and well-being of Syrian families. The lessons drawn from this research can be applied both within areas of displacement and in post-resettlement settings where issues of economic precarity can often persist

Carry Trade with Maintained Currencies - A Risk and Return Analysis for the Egyptian Pound

The forward premium puzzle in the exchange rate market, resulting from the deviation and failure of interest rate parity, has awakened the interest of speculators to perform carry trade activities. Across literature the main risk associated and measured for carry trade has been the exchange rate risk and crash risk related to the relevant currencies used. But within the literature, the influence of maintained currencies on the carry trade results has not yet been covered. This paper analyzes the potential performance and the risk of carry trade strategies within a maintained exchange rate regime. For this analysis an empirical study of carry trade strategies applied between the EGP and other currencies has been used and compared to those with the USD as an example for a maintained exchange rate. Our risk and return analysis clearly shows a combination of high return and low risk for the maintained currency carry trade.Carry Trade Performance, Uncovered Interest Parity, Maintained Exchange Rates, Value at Risk

Adsorption of Sugars on Al- and Ga-doped Boron Nitride Surfaces: A Computational Study

Molecular adsorption on surfaces is a key element for many applications, including sensing and catalysis. Non-invasive sugar sensing has been an active area of research due to its importance to diabetes care. The adsorption of sugars on a template surface study is at the heart of matter. Here, we study doped hexagonal boron nitride sheets ($h$-BNNs) as adsorbing and sensing template for glucose and glucosamine. Using first principles calculations, we find that the adsorption of glucose and glucosamine on $h$-BNNs is significantly enhanced by the substitutional doping of the sheet with Al and Ga. Including long range van der Waals corrections gives adsorption energies of about 2 eV. In addition to the charge transfer occurring between glucose and the Al/Ga-doped BN sheets, the adsorption alters the size of the band gap, allowing for optical detection of adsorption. We also find that Al-doped boron nitride sheet is better than Ga-nitride sheet to enhance the adsorption energy of glucose and glucosamine. The results of our work can be potentially utilized when designing support templates for glucose and glucosamine

The geodesics structure of Schwarzschild electromagnetic black hole

The geodesic equations are considered in static mass imbedded in a uniform electromagnetic field. Due to electromagnetic field horizon shrinks and geodesics are modified. By analyzing the behavior of the effective potentials for the massless and massive particle we study the radial and circular trajectories. Radial geodesics for both photons and particles are solved exactly. It is shown that a particle falls toward the horizon in a finite proper time slows down so that the particle reaches the singularity in longer time than Schwarzschild case. Timelike and null circular geodesics are investigated. We have shown that, there is no stable circular orbits for photons, however stable and unstable second kind orbits are exists for massive particle. An exact analytical solution for the innermost circular orbits (ISCO) has been obtained. It has been shown that the radius of ISCO shrinks due to the presence of electromagnetic field.Comment: 21 pages, 14 figure

Treatment of Gingival Recession

Gingival recession is an intriguing and complex phenomenon. Recession frequently disturbs patients because of sensitivity and esthetics. Many surgical techniques have been introduced to treat gingival recession, including those involving autogenous tissue grafting, various flap designs, orthodontics, and guided tissue regeneration (GTR). This article describes different clinical approaches to treat gingival recession with emphasis on techniques that show promising results and root coverage
