Assessing The Impact Of The Global Financial Crisis On GCC Countries

No doubt, the international financial crisis that started in the United States of America will cast its effects on all countries of the world, developed and developing. Yet these effects vary from one country to another for several reasons. The GCC countries would not escape these negative effects of this severe crisis. The negative effects of the crisis on gulf countries come from many aspects: first, decrease in price of oil on whose revenues the development programs in these countries depend; second, decrease in the value of US$and the subsequent decrease in the assets owned by these countries in US$; third, a case of economic stagnation will prevail in the world with effects starting to appear. It is obvious that this would be reflected on the real sector in the economies causing a series of negative effects through decrease of the world demand for exports of GCC countries of oil, petrochemicals and aluminum.  Lastly, increased inflation rates with decreased interest rates will result in a decrease in real interest with an accompanying decrease in incentives for saving and consequently investment and economic development. The main aim of the research is to assess the economic effects of the global financial crisis on GCC countries. The paper results are that the big reserves of foreign currencies achieved by the GCC countries in the past few years have helped increase their ability to bear the effects of the financial effects on one hand and their ability to adopt expansionary policies through pumping liquidity to absorb the regressive effects of the crisis on the other. The paper recommends the necessity of taking precautionary procedures for the effects which will result from the expansionary policies effective in GCC countries

Estimation Of The Economic Impact Of Brain Drain On The Labor Expelling Country

The emigration of human resources leads to many losses for the labor expelling country. Such losses would, without doubt, adversely affect the economic and social development programs in multiple aspects including state loss of migrants efforts in producing the desired growth whether in the planning and preparation stages or in the implementation stage and the cost opportunity represented in the financial resources spent on the migrants prior to their emigration which could have been utilized in other areas taking into account, the limited financial resources in the underdeveloped countries which are mainly labor expelling countries. Hence, the loss of such countries is doubled. They neither benefited from their labor after years of spending in education and health, nor they saved their funds and exploited in other alternatives like improving education and health services, providing job opportunities for residents, improving the innovation climate or even increasing civil production to improve the living standards of individuals. The study is devoted to analyze and measure of economic effects of labor emigration in the labor expelling economy, through taking Egypt – the largest Arab country suffering from this phenomenon- as an example and using data derived from Egyptian sources. Estimates have emphasized growing losses generated by the Egyptian labor emigration, especially by brain drain. The paper concludes that measures and policies must be adopted to stop this drain by addressing the causes of labor emigration or rather, the existing properties of the labor expelling country. Also, efforts must be made to ensure that data related to immigration is always available, updated and estimated by official bodies having human, financial and technical capabilities for this task

Poly (amido amine) dendrimer based membranes for wastewater treatment - A critical review

Membrane based wastewater treatment technologies in which polymeric membranes are most commonly used have been extensively applied in water/wastewater treatment to help address the issue of water shortage through water/wastewater reclamation and reuse. However, polymeric membranes due to their hydrophobic nature are subject damage caused by accumulation of organic/inorganic fouling during filtration processes, which results in a number of issues such as low water flux and low pollutant rejection. Several strategies have been considered to address these challenges and effectively improve the membrane performances. Alteration of membrane properties strategy using suitable nanofillers such us poly (amido amine) or PAMAM has been largely studied. Herein, research efforts regarding the synthesis and properties of PAMAM along with the synthesis of PAMAM multifunctional nanocomposites were concisely reviewed for the first time. Membrane performance enhancement by incorporation of PAMAM were reviewed and discussed. Results and contributions achieved in the improvement of PAMAM incorporated membranes for the treatment of different types of wastewaters has been reviewed and summarized.

The type II RAF inhibitor tovorafenib in relapsed/refractory pediatric low-grade glioma: the phase 2 FIREFLY-1 trial

\ua9 2023, The Author(s).BRAF genomic alterations are the most common oncogenic drivers in pediatric low-grade glioma (pLGG). Arm 1 (n = 77) of the ongoing phase 2 FIREFLY-1 (PNOC026) trial investigated the efficacy of the oral, selective, central nervous system–penetrant, type II RAF inhibitor tovorafenib (420 mg m−2 once weekly; 600 mg maximum) in patients with BRAF-altered, relapsed/refractory pLGG. Arm 2 (n = 60) is an extension cohort, which provided treatment access for patients with RAF-altered pLGG after arm 1 closure. Based on independent review, according to Response Assessment in Neuro-Oncology High-Grade Glioma (RANO-HGG) criteria, the overall response rate (ORR) of 67% met the arm 1 prespecified primary endpoint; median duration of response (DOR) was 16.6 months; and median time to response (TTR) was 3.0 months (secondary endpoints). Other select arm 1 secondary endpoints included ORR, DOR and TTR as assessed by Response Assessment in Pediatric Neuro-Oncology Low-Grade Glioma (RAPNO) criteria and safety (assessed in all treated patients and the primary endpoint for arm 2, n = 137). The ORR according to RAPNO criteria (including minor responses) was 51%; median DOR was 13.8 months; and median TTR was 5.3 months. The most common treatment-related adverse events (TRAEs) were hair color changes (76%), elevated creatine phosphokinase (56%) and anemia (49%). Grade ≥3 TRAEs occurred in 42% of patients. Nine (7%) patients had TRAEs leading to discontinuation of tovorafenib. These data indicate that tovorafenib could be an effective therapy for BRAF-altered, relapsed/refractory pLGG.

Imports and isotopes: a modern baseline study for interpreting Iron Age and Roman trade in fallow deer antlers

The European Fallow deer (Dama dama dama) became extinct in the British Isles and most of continental Europe at the time of the Last Glacial Maximum, with the species becoming restricted to an Anatolian refugium (Masseti et al. 2008). Human-mediated reintroductions resulted in fallow populations in Rhodes, Sicily, Mallorca, Iberia and other parts of western Europe (Sykes et al. 2013). Eventually, the species was brought to Britain by the Romans during the 1st century AD, with a breeding population being established at Fishbourne Roman Palace (Sykes et al. 2011). The human influence on the present-day distribution of the species makes it particularly interesting from a zooarchaeological perspective. This paper describes my MSc research, as part of the AHRC-funded project Dama International: Fallow Deer and European Society 6000 BC–AD 1600, looking at antlers from Iron Age and Roman sites in Britain for evidence of trade in body parts and whether this can be elucidated by a parallel stable isotope study of modern fallow antlers of known provenance

The Arab Spring: Do We Need a New Theory?

The waves of the Arab Spring in Tunisia, Egypt, Libya, Yemen and Syria, and any other country that may follow, is considered a unique phenomenon worth studying in view of the pre and post revolution events and effects on all sectors of the national economy, as well as their interlocking effects on the global economy. The current research aims at studying the concepts of the Arab Spring, its causes and its most important consequences, as well as the ability of the current economic theory to interpret such events. The most important results of the research lies in the need for a new theory to explain the Arab Spring revolutions, the new theory should based on showing how important was the technological revolution in the field of communications, the use of violence against the rebels, and legitimate demands of re-bels in continuation and success of the revolutions of the Arab Spring
