Book Description
The scientists from the Northwest African region expressed their commitment to conduct their own acoustic surveys. All of the local research vessels conducted acoustic surveys in 2004. The ability of running acoustic surveys in the sub-region has developed to a good level and focus in the future should be on the development of human capacity and to resolve the recurrent technical problems of trawl performance, noise discrimination and data storage. The timeframe of the continued surveys with R/V DR. FRIDTJOF NANSEN and the support through the Nansen Programme is unknown and high priority must therefore be given to the improvement of scientists skills in acoustic abundance estimation.

Book Description
The report finds that all of the local research vessels conducted acoustic surveys in 2005 and major improvements have been made in standardisation of procedures and processing of data. Some problems still persist, such as problems with trawling using the pelagic trawl and problems related to noise levels, but these issues are now being addressed. Plans were made for a second parallel survey and intercalibration exercise to take place in October- December 2005. It was recommended that the countries in the Northwest African region, Senegal, the Gambia, Mauritania and Morocco should co-ordinate their survey effort to conduct two annual regional acoustic surveys, during the cold and warm seasons respectively.

Book Description
The fourth meeting of the FAO/CECAF Working Group on the Assessment of Small Pelagic Fish – Subgroup South was held in Elmina, Ghana from 12-20 September 2018. The overall objective of the Working Group is to contribute to the improved management of small pelagic resources in West Africa through the assessment of the state of the stocks and fisheries in order to ensure sustainable use of these resources for the benefit of coastal countries. The species assessed by the Working Group were: sardinella (Sardinella aurita and Sardinella maderensis), bonga (Ethmalosa fimbriata), anchovy (Engraulis encrasicolus) and horse mackerel (Trachurus trecae and Decapterus rhonchus), and other Carangidae, in the region between the northern border of Guinea-Bissau and the southern border of Angola. La quatrième réunion du Groupe de travail FAO/COPACE sur l’évaluation des petits pélagiques – Sous-groupe Sud, s’ets tenue à Elmina, Ghana, du 12 au 20 septembre 2018. L’objectif général du Groupe de travail est d’améliorer la gestion des ressources en petits pélagiques en Afrique de l’Ouest grâce à l’évaluation de l’état des stocks et des pêcheries de façon à assurer une utilisation durable de ces ressources au bénéfice des pays côtiers. Les espèces évaluées par le Groupe de travail sont les suivantes: les sardinelles (Sardinella aurita et t Sardinella maderensis), l’ethmalose (Ethmalosa fimbriata), l’anchois (Engraulis encrasicolus) et les chinchards (Trachurus trecae et Decapterus rhonchus) et autres carangidés, dans la région située entre la frontière nord de la Guinée-Bissau et la frontière sud de l’Angola.

Book Description
Berbers, also known as Imazighen, are the ancient inhabitants of North Africa, but rarely have they formed an actual kingdom or separate nation state. Ranging anywhere between 15-50 million, depending on how they are classified, the Berbers have influenced the culture and religion of Roman North Africa and played key roles in the spread of Islam and its culture in North Africa, Spain, and Sub-Saharan Africa. Taken together, these dynamics have over time converted to redefine the field of Berber identity and its socio-political representations and symbols, making it an even more important issue in the 21st century. This second edition of Historical Dictionary of the Berbers contains a chronology, an introduction, appendixes, and an extensive bibliography. The dictionary section has over 200 cross-referenced entries on important personalities, places, events, institutions, and aspects of culture, society, economy, and politics. This book is an excellent resource for students, researchers, and anyone wanting to know more about the Berbers.

Book Description
George C. Marshall once called him "the brains of the army." And yet General Lesley J. McNair (1883-1944), a man so instrumental to America's military preparedness and Army modernization, remains little known today, his papers purportedly lost, destroyed by his wife in her grief at his death in Normandy. This book, the product of an abiding interest and painstaking research, restores the general Army Magazine calls one of "Marshall's forgotten men" to his rightful place in American military history. Because McNair contributed so substantially to America's war preparedness, this first complete account of his extensive and varied career also leads to a reevaluation of U.S. Army effectiveness during WWII. Born halfway between the Civil War and the dawn of the 20th century, Lesley McNair–"Whitey" by his classmates for his blond hair–graduated 11th of 124 in West Point's class of 1904 and rose slowly through the ranks like all officers in the early twentieth century. He was 31 when World War I erupted, 34 and a junior officer when American troops prepared to join the fight. It was during this time, and in the interwar period that followed the end of the First World War, that McNair's considerable influence on Army doctrine and training, equipment development, unit organization, and combined arms fighting methods developed. By looking at the whole of McNair's career–not just his service in WWII as chief of staff, General Headquarters, 1940-1942, and then as commander, Army Ground Forces, 1942-1944–Calhoun reassesses the evolution and extent of that influence during the war, as well as McNair's, and the Army's, wartime performance. This in-depth study tracks the significantly positive impact of McNair's efforts in several critical areas: advanced officer education; modernization, military innovation, and technological development; the field-testing of doctrine; streamlining and pooling of assets for necessary efficiency; arduous and realistic combat training; combined arms tactics; and an increasingly mechanized and mobile force. Because McNair served primarily in staff roles throughout his career and did not command combat formations during WWII, his contribution has never received the attention given to more public–and publicized–military exploits. In its detail and scope, this first full military biography reveals the unique and valuable perspective McNair's generalship offers for the serious student of military history and leadership.
