  Teaching the Trees - Lessons...

  In this collection of natural-history essays, biologist Joan Maloof embarks on a series of lively, fact-filled expeditions into forests of the eastern United States. Through Maloof's engaging, conversational style, each essay offers a lesson in stewardship as it explores the interwoven connections between a tree species and the animals and insects whose lives depend on it—and who, in turn, work to ensure the tree's survival.Never really at home in a laboratory, Maloof took to the woods early in her career. Her enthusiasm for firsthand observation in the wild spills over into her writing, whether the subject is the composition of forest air, the eagle's preference for nesting in loblolly pines, the growth rings of the bald cypress, or the gray squirrel's fondness for weevil-infested acorns. With a storyteller's instinct for intriguing particulars, Maloof expands our notions about what a tree "is" through her many asides—about the six species of leafhoppers who eat only sycamore leaves or the midges who live inside holly berries and somehow prevent them from turning red.As a scientist, Maloof accepts that trees have a spiritual dimension that cannot be quantified. As an unrepentant tree hugger, she finds support in the scientific case for biodiversity. As an activist, she can't help but wonder how much time is left for our forests.

  This is a book of miracles-medical events witnessed by leading physicians for which there is no reasonable medical explanation, or, if there is, the explanation itself is extraordinary. These dramatic first-person essays detail spectacular serendipities, impossible cures, breathtaking resuscitations, extraordinary awakenings, and recovery from unimaginable disasters. Among the extraordinary cases poignantly recounted by the physicians witnessing them:A priest visiting a hospitalized patient went into cardiac arrest on the elevator, which opened up on the cardiac floor, right at the foot of the cardiac specialist, at just the right moment.A tiny premature baby dying from irreversible lung disease who recovered almost immediately after being taken from his hospital bed and placed on his mother's chest.President John F. Kennedy's son Patrick, who died shortly after birth, and whose disease eventually led to research that saved generations of babies.     Miracles We Have Seen is a book of inspiration and optimism, and a compelling glimpse into the lives of physicians.

  The Topics is is the fifth of Aristotle's six texts on logic which are collectively known as the Organon ("Instrument"). The Topics constitutes Aristotle's treatise on the art of dialectic—the invention and discovery of arguments in which the propositions rest upon commonly-held opinions or endoxa. Topoi are "places" from which such arguments can be discovered or invented. In his treatise on the Topics, Aristotle does not explicitly define a topos, though it is "at least primarily a strategy for argument not infrequently justified or explained by a principle."

  Wirral in the Great War

  On 4 August 1914 Britain declared war on Germany. Originally perceived as a short campaign to curtail Germanic imperialism, it developed into a four-year long war of attrition. The Great War is justifiably associated with the horrors of trench warfare and the death of a generation but history has overlooked the home fronts' colossal contribution to victory.On the outbreak of war thousands of troops arrived in Wirral to defend the coast from invasion and guard the docks and shipyards under the watchful eyes of the gunners of the Bidston Hill artillery batteries. The transition to a military garrison also led to the conversion of schools to military hospitals, predominately financed by the community. Thousands of wounded service men arriving at Woodside station were dispersed and administered to by a plethora of military or auxiliary hospitals. Voluntary organizations also procured funds for ambulances and comforts for those at the front. At the beginning of hostilities, the Government swiftly introduced draconian regulations to restrict liberty, particularly for those of foreign extraction. Following the 1915 sinking of the Lusitania, the xenophobia vented itself in Wallasey and Birkenhead where riots resulted in the destruction of German owned business premises. The resentment was further fueled by the German submarines attempt to destroy the British merchant fleet and starve Britain into submission  they almost succeeded. As vital cargoes plunged to the sea bed, food became the latest rationed commodity; consequently unused tracts of Wirral land were turned over to food production and German prisoners of war helped clear the river Birkett. The local shipyards and factories came under the control of the Ministry of Munitions and unlikely companies were involved in the national preoccupation of producing artillery shells. Following the 1916 introduction of compulsory military service, female workers increasingly replaced the men thereby making undreamed of advances in female emancipation. Also involved in the war effort were school children who collected food for wounded soldiers, boy scouts patrolled the coastline, 'sister Susie famously sewed shirts for soldiers' and a Dad's Army was established to repel invaders. Their activities and others are generally overlooked by twentieth century chroniclers.This is the fascinating, but forgotten story of how Wirral provided the sinews for war, and made a significant contribution to the comprehensive defeat of Germany.
