Environmental History
Environmental history is the study of human interaction with the natural world over time, emphasising the active role nature plays in influencing human affairs and vice versa. Environmental history first emerged in the United States out of the environmental movement of the 1960s and 1970s, and much of its impetus still stems from present-day global environmental concerns. The field was founded on conservation issues but has broadened in scope to include more general social and scientific history and may deal with cities, population or sustainable development. As all history occurs in the natural world, environmental history tends to focus on particular time-scales, geographic regions, or key themes. It is also a strongly multidisciplinary subject that draws widely on both the humanities and natural science. The subject matter of environmental history can be divided into three main components. The first, nature itself and its change over time, includes the physical impact of hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Attitude (psychology)
In psychology, attitude is a psychological construct that is a mental and emotional entity that inheres or characterizes a person, their attitude to approach to something, or their personal view on it. Attitude involves their mindset, outlook and feelings. Attitudes are complex and are an acquired state through life experience. Attitude is an individual's predisposed state of mind regarding a value and it is precipitated through a responsive expression towards oneself, a person, place, thing, or event (the attitude object) which in turn influences the individual's thought and action. Most simply understood attitudes in psychology are the feelings individuals have about themselves and the world. Prominent psychologist Gordon Allport described this latent psychological construct as "the most distinctive and indispensable concept in contemporary social psychology."Allport, Gordon. (1935). "Attitudes," in A Handbook of Social Psychology, ed. C. Murchison. Worcester, MA: Clark Univers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historiography
Historiography is the study of the methods of historians in developing history as an academic discipline, and by extension is any body of historical work on a particular subject. The historiography of a specific topic covers how historians have studied that topic using particular sources, techniques, and theoretical approaches. Scholars discuss historiography by topic—such as the historiography of the United Kingdom, that of WWII, the British Empire, early Islam, and China—and different approaches and genres, such as political history and social history. Beginning in the nineteenth century, with the development of academic history, there developed a body of historiographic literature. The extent to which historians are influenced by their own groups and loyalties—such as to their nation state—remains a debated question. In the ancient world, chronological annals were produced in civilizations such as ancient Egypt and Mesopotamia. However, the discipline of his ...

The Columbian Exchange
''The Columbian Exchange: Biological and Cultural Consequences of 1492 '' is a 1972 book on the Columbian exchange by Alfred W. Crosby. Reception Various academic authorities have reviewed the book. In the foreword to the 2003 edition of the book, J. R. McNeill says that in 1972 "Crosby's ideas met with indifference from most historians, neglect from many publishers, and hostility from at least some reviewers, (but) they now figure prominently in conventional presentations of modern history." Today, the book is a founding text of the field of environmental history. Its themes have been expanded upon and popularized by later works such as ''1491: New Revelations of the Americas Before Columbus'' (2005) and ''1493: Uncovering the New World Columbus Created'' (2012) by Charles C. Mann. References {{DEFAULTSORT:Columbian Exchange 1972 non-fiction books Environmental history Non-fiction books about indigenous peoples of the Americas 1972 in the environment ...

Science
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ...
