Ibn Khaldun can be regarded as the earliest scientific systematic sociologist. The modern sociology, emerged in the early 19th century as the academic response to the modernization of the world. Among many early sociologists (e.g., Emile Durkheim), the aim of sociology was in structuralism, understanding the cohesion of social groups, and developing an "antidote" to social disintegration. Max Weber was concerned with the modernization of society through the concept of rationalization, which he believed would trap individuals in an "iron cage" of rational thought. Some sociologists, including Georg Simmel and W. E. B. Du Bois, utilized more microsociological, qualitative analyses. This microlevel approach played an important role in American sociology, with the theories of George Herbert Mead and his student Herbert Blumer resulting in the creation of the symbolic interactionism approach to sociology.

Though known since antiquity the commercial growing of cotton in Egypt only started in 1820's, following a Frenchman, by the name of M. Jumel, propositioning the then ruler, Mohamed Ali Pasha, that he could earn a substantial income by growing an extra-long staple Maho (Barbadence) cotton, in Lower Egypt, for the French market. Mohamed Ali Pasha accepted the proposition and granted himself the monopoly on the sale and export of cotton in Egypt; and later dictated cotton should be grown in preference to other crops. By the time of the American Civil war annual exports had reached $16 million (120,000 bales), which rose to $56 million by 1864, primarily due to the loss of the Confederate supply on the world market. Exports continued to grow even after the reintroduction of US cotton, produced now by a paid workforce, and Egyptian exports reached 1.2 million bales a year by 1903.

Authorized headdress for the Canadian Armed Forces are the: beret, wedge cap, ballcap, Yukon cap, and tuque (toque). Each is coloured according to the distinctive uniform worn: navy (white or navy blue), army (rifle green or "regimental" colour), air force (light blue). Adherents of the Sikh faith may wear uniform turbans (dastar) (or patka, when operational) and Muslim women may wear uniform tucked hijabs under their authorized headdress. Jews may wear yarmulke under their authorized headdress and when bareheaded. The beret is probably the most widely worn headgear and is worn with almost all orders of dress (with the exception of the more formal orders of Navy and Air Force dress), and the colour of which is determined by the wearer's environment, branch, or mission. Naval personnel, however, seldom wear berets, preferring either service cap or authorized ballcaps (shipboard operational dress), which only the Navy wear. Air Force personnel, particularly officers, prefer the wedge cap to any other form of headdress. There is no naval variant of the wedge cap. The Yukon cap and tuque are worn only with winter dress, although clearance and combat divers may wear tuques year-round as a watch cap. Soldiers in Highland, Scottish, and Irish regiments generally wear alternative headdress, including the glengarry, balmoral, tam o'shanter, and caubeen instead of the beret. The officer cadets of both Royal Military Colleges wear gold-braided "pillbox" (cavalry) caps with their ceremonial dress and have a unique fur "Astrakhan" for winter wear. The Canadian Army wears the CG634 helmet.

What are some of the authorized head dresses for the CAF?
