Notes, Definitions, and Abbreviations (continued)
Opium is the milky exudate of the incised, unripe seedpod of the opium poppy.
Opium poppy (Papaver somniferum) is the source for many natural and semisynthetic narcotics.
Poppy straw concentrate is the alkaloid derived from the mature dried opium poppy.
Qat (kat, khat) is a stimulant from the buds or leaves of Catha edulis and is chewed or drunk as tea.
Stimulants are drugs that relieve mild depression, increase energy and activity, and include cocaine (coke, snow, crack), amphetamines (Desoxyn, Dexedrine), phenmetrazine (Preludin), methylphenidate (Ritalin), and others (Cylert, Sanorex, Tenuate).
Infant mortality rate: The number of deaths to infants under one year of age in a given year per 1,000 live births occurring in the same year.
Land use: Human use of the land surface is categorized as arable land—land cultivated for crops that are replanted after each harvest (wheat, maize, rice); permanent crops—land cultivated for crops that are not replanted after each harvest (citrus, coffee, rubber); meadows and pastures—land permanently used for herbaceous forage crops; forest and woodland—land under dense or open stands of trees; and other—any land type not specifically mentioned above (urban areas, roads, desert). The percentage figure for irrigated refers to the portion of the entire amount of land area that is artificially supplied with water.
Leaders: The chief of state is the titular leader of the country who represents the state at official and ceremonial functions but is not involved with the day-to-day activities of the government. The head of government is the administrative leader who manages the day-to-day activities of the government. In the UK, the monarch is the chief of state and the prime minister is the head of government. In the US, the President is both the chief of state and the head of government.
Life expectancy at birth: The average number of years to be lived by a group of people all born in the same year, if mortality at each age remains constant in the future.
Maritime claims: The proximity of neighboring states may prevent some national claims from being fully extended.
Merchant marine: All ships engaged in the carriage of goods. All commercial vessels (as opposed to all nonmilitary ships), which excludes tugs, fishing vessels, offshore oil rigs, etc. Also, a grouping of merchant ships by nationality or register.
Captive register—A register of ships maintained by a territory, possession, or colony primarily or exclusively for the use of ships owned in the parent country. Also referred to as an offshore register, the offshore equivalent of an internal register. Ships on a captive register will fly the same flag as the parent country, or a local variant of it, but will be subject to the maritime laws and taxation rules of the offshore territory. Although the nature of a captive register makes it especially desirable for ships owned in the parent country, just as in the internal register, the ships may also be owned abroad. The captive register then acts as a flag of convenience register, except that it is not the register of an independent state.
Flag of convenience register— A national register offering registration to a merchant ship not owned in the flag state. The major flags of convenience (FOC) attract ships to their register by virtue of low fees,
