Jacques-Antoine-Hippolyte, comte de Guibert: Father of the Grande Armée

Description: The eighteenth century was a time of intense upheaval in France. The death of Louis XIV in 1715 and the subsequent reign of Louis XV saw the end of French political and martial hegemony on the continent. While French culture and language remained dominant in Europe, Louis XV's disinterested rule and military stagnation led to the disastrous defeat of the French army at the hands of Frederick the Great of Prussia in the Seven Years War (1756-1763). The battle of Rossbach marked the nadir of th… more

Conglomerate Performance as Influenced by Selected Management Practices

Description: The latest surge of corporate mergers has been characterized by a steadily increasing rate of conglomerate combinations. It would appear that one of the prime motivating factors in conglomerate merger is a firm belief in the principle of "synergism," or the mutually cooperating action of separate substances taken together to produce an effect greater than that of any component taken alone. It would also appear that in such instances wherein there is no direct relationship in regard to raw mater… more
