Context and question: Political economy in anthropology is the application of the theories and methods of Historical Materialism to the traditional concerns of anthropology, including, but not limited to, non-capitalist societies. Political Economy introduced questions of history and colonialism to ahistorical anthropological theories of social structure and culture. Three main areas of interest rapidly developed. The first of these areas was concerned with the "pre-capitalist" societies that were subject to evolutionary "tribal" stereotypes. Sahlins work on Hunter-gatherers as the 'original affluent society' did much to dissipate that image. The second area was concerned with the vast majority of the world's population at the time, the peasantry, many of whom were involved in complex revolutionary wars such as in Vietnam. The third area was on colonialism, imperialism, and the creation of the capitalist world-system. More recently, these Political Economists have more directly addressed issues of industrial (and post-industrial) capitalism around the world.
What have Political Economists most recently focused on the issues of?
Answer: industrial (and post-industrial) capitalism
Context and question: International teams also play friendlies, generally in preparation for the qualifying or final stages of major tournaments. This is essential, since national squads generally have much less time together in which to prepare. The biggest difference between friendlies at the club and international levels is that international friendlies mostly take place during club league seasons, not between them. This has on occasion led to disagreement between national associations and clubs as to the availability of players, who could become injured or fatigued in a friendly.
Why are Friendly's nonessential for major tournaments?
Answer: unanswerable
Context and question: By the 1890s the profound effect of adrenal extracts on many different tissue types had been discovered, setting off a search both for the mechanism of chemical signalling and efforts to exploit these observations for the development of new drugs. The blood pressure raising and vasoconstrictive effects of adrenal extracts were of particular interest to surgeons as hemostatic agents and as treatment for shock, and a number of companies developed products based on adrenal extracts containing varying purities of the active substance. In 1897 John Abel of Johns Hopkins University identified the active principle as epinephrine, which he isolated in an impure state as the sulfate salt. Industrial chemist Jokichi Takamine later developed a method for obtaining epinephrine in a pure state, and licensed the technology to Parke Davis. Parke Davis marketed epinephrine under the trade name Adrenalin. Injected epinephrine proved to be especially efficacious for the acute treatment of asthma attacks, and an inhaled version was sold in the United States until 2011 (Primatene Mist). By 1929 epinephrine had been formulated into an inhaler for use in the treatment of nasal congestion.
Who identified the active substance?
Answer:
John Abel
