Article history: Received October 1, 2011 Received in Revised form November, 14, 2011 Accepted 30 January 2012 Available online 20 February 2012 In this study, the backpropagation neural network (BPNN) is tested for the ability to forecast the daily volatility of two stock market indices from the Middle East and North Africa (MENA) region using volume; namely Morocco and Saudi Arabia. Volatilit...

Social networks have been resorted to as effective platforms for social mobility in many parts of the world. This mobility occurs when social media users exploit their interpersonal relationships, especially their ‘weak ties’ (Granovetter, 1973). Social networks enable their users to be producers of information, rather than mere consumers, and to be socially and politically well-informed. They ...

INTRODUCTION Visceral leishmaniasis (VL) is a neglected parasitic disease with a high fatality rate if left untreated. Endemic in Morocco, as well as in other countries in the Mediterranean basin, VL mainly affects children living in rural areas. In Morocco, the direct observation of Leishmania parasites in bone marrow (BM) aspirates is used to diagnose VL and meglumine antimoniate (SB) is the ...

The aim of this study was to investigate the prevalence and diversity of infectious bronchitis virus (IBV) genotypes in poultry flocks in 16 areas of Morocco between 2010 and 2014. A total of 360 chicken flocks suspected of being infected by IBV were screened for the IBV N gene using real-time reverse transcriptase-polymerase chain reaction (RT-PCR). Flocks were classified into four groups acco...

To assess the extent and severity of poisoning by Atractylis gummifera L. in Morocco, a descriptive retrospective study was conducted on all the poisoning cases listed between 1981 and 2004 to the Morocco Poison Control Center. During this period, 240 people were hospitalized for glue thistle poisoning, 72% of which are children under 16 years. The severity of the poisoning has been affirmed by...

Tuberculosis is a contagious disease that usually attacks the lungs but sometimes attacks other parts of the body, such as the kidneys, glands, and bones. It is an endemic and major public health problem in Morocco. Tuberculosis is transmitted through the airways via the inhalation of microdroplets containing Mycobacterium tuberculosis We present here the whole-genome shotgun sequences of three...

I read with great interest the article by Alavi-Moghaddam et al. (1) in which the authors concluded that application of the queuing theory analysis can improve movement and reduce the waiting times of patients in bottlenecks within the emergency department (ED) in Iran. As an epidemiologist in Morocco, I divide the frustration of the authors that throughput of patients in the emergency departme...

Monthly precipitation data from the Global Historical Climatology Network for 42 stations in Morocco and its vicinity are investigated with respect to baroclinicity, storm track and cyclone activity, moisture transports, North Atlantic Oscillation (NAO) variations, and different circulation types by means of correlation and composite studies. The results are related to a climate change scenario...

Detecting population substructure and ancestry is a critical issue for both association studies of health behaviors and forensic genetics. Determining aspects of a population's genetic history as potential sources of substructure can aid in design of future genetic studies. Within this context, fifteen autosomal short tandem repeat (STR), were used to examine population genetic structure and hy...
