This collection of squadron histories has been prepared by the USAF Historical Division to complement the Division's book, Air Force Combat Units of World War II. The 1,226 units covered by this volume are the combat (tactical) squadrons that were active between 7 December 1941 and 2 September 1945. Each squadron is traced from its beginning through 5 March 1963, the fiftieth anniversary of the organization of the 1st Aero (later Bombardment) Squadron, the first Army unit to be equipped with aircraft for tactical operations. For each squadron there is a statement of the official lineage and data on the unit's assignments, stations, aircraft and missiles, operations, service streamers, campaign participation, decorations, and emblem.

The Condition of the Working Class in England is one of the best-known works of Friedrich Engels. Originally written in German as Die Lage der arbeitenden Klasse in England, it is a study of the working class in Victorian England. It was also Engels' first book, written during his stay in Manchester from 1842 to 1844. Manchester was then at the very heart of the Industrial Revolution, and Engels compiled his study from his own observations and detailed contemporary reports. Engels argues that the Industrial Revolution made workers worse off. He shows, for example, that in large industrial cities mortality from disease, as well as death-rates for workers were higher than in the countryside. In cities like Manchester and Liverpool mortality from smallpox, measles, scarlet fever and whooping cough was four times as high as in the surrounding countryside, and mortality from convulsions was ten times as high as in the countryside. The overall death-rate in Manchester and Liverpool was significantly higher than the national average (one in 32.72 and one in 31.90 and even one in 29.90, compared with one in 45 or one in 46). An interesting example shows the increase in the overall death-rates in the industrial town of Carlisle where before the introduction of mills (1779–1787), 4,408 out of 10,000 children died before reaching the age of five, and after their introduction the figure rose to 4,738. Before the introduction of mills, 1,006 out of 10,000 adults died before reaching 39 years old, and after their introduction the death rate rose to 1,261 out of 10,000.

The science and practice of psychology has evolved around the world on different trajectories and timelines, yet with a convergence on the recognition of the need for a human science that can confront the challenges facing the world today. Few would argue that the standard narrative of the history of psychology has emphasized European and American traditions over others, but in today's global culture, there is a greater need in psychology for international understanding. This volume describes the historical development of psychology in countries throughout the world. Contributors provide narratives that examine the political and socioeconomic forces that have shaped their nations' psychologies. Each unique story adds another element to our understanding of the history of psychology. The chapters in this volume remind us that there are unique contexts and circumstances that influence the ways in which the science and practice of psychology are assimilated into our daily lives. Making these contexts and circumstances explicit through historical research and writing provides some promise of greater international insight, as well as a better understanding of the human condition.

What is morally permissible, and what is morally obligatory? These questions form the core of a vast amount of philosophical reasoning. In his Fundamental Principles of the Metaphysics of Morals, Immanuel Kant developed a basis for the answers. In this landmark work, the German philosopher asks what sort of maxim might function as a guide to appropriate action under a given set of circumstances. By universalizing such a maxim, would morally permissible behavior not become clear? Suppose that everyone were to behave in accordance with this maxim. If everyone followed the maxim in the same way without harm to civilized culture, then the behavior would be morally permissible. But what if no one followed the maxim? Would civilization thereby be at risk? In such a case, the behavior would be morally obligatory. Kant's test, known as the Categorical Imperative, is a logical proof of the Golden Rule and the centerpiece of this work. It constitutes his best-known contribution to ethical discussion, and a familiarity with his reasoning in this book is essential to students of philosophy, religion, and history.
