• Boxing.

  C Offensive Techniques To be effective, boxers must have an assortment of punches that are coordinated with their footwork.

C1 Feinting Moving the hands or head to confuse an opponent is called feinting. A smart boxer will first test the opponent by trying different feints, noting the reaction to each onebefore deciding which will b...

  line or rotates in any direction. Each canal also contains sensory areas with sensory hair cells that project into a cone-shaped cap of gelatin. Two of the semicircularcanals are in a vertical position and are used to detect vertical movement, such as jumping or falling. The third canal is horizontal and detects horizontal movement,such as turning or spinning. The action of the canals depends on the inertia of the fluid inside. When the motion of the body changes, the fluid lags behind, causing...

• Trinidad and Tobago - country.

Blacks of African ancestry andAsians of Indian ancestry each make up about 40 percent of the population. The remainder is mainly of mixed ancestry, although there are also small groups of peopleof Chinese, European, South American, and Middle Eastern descent. The ethnic diversity of Trinidad and Tobago owes its origins to slavery and its abolition. Afr...

• Spread of Islam - History.

  Muhammad died in 632 and was succeeded by Abu Bakr, the father of Muhammad’s favorite wife, Aisha. Abu Bakr was the first caliph ( khalifah, Arabic for “successor”) of Islam. Like Muhammad, Abu Bakr was a member of the Quraysh clan. While neither Abu Bakr nor any subsequent caliph claimed the role of prophet, they wereleaders of this new religious enterprise that was quickly becoming a political entity as well. The first four caliphs, all of whom were selected by some form of council ofMuslims,...

• Molecule - chemistry.

  attracted to the negatively charged electrons between them. The electrons belong to the molecule as a whole. However, each hydrogen atom now has a complete outershell of two electrons. The formula H 2 describes a hydrogen molecule, a discrete unit. When a molecule contains just two atoms, such as the hydrogen molecule does, it is called a diatomic molecule. Some atoms can form covalent bonds with more than one other atom and thus create a larger molecule. Atoms form molecules with covalent bo...

• Criminal Punishment.

  In the United States and Canada, younger offenders may be sentenced to highly regimented, military-style correctional programs known as boot camps. Generally,offenders volunteer to participate in boot camp programs to avoid other types of incarceration. At boot camps, officials subject offenders to strict discipline and physicaltraining. They also provide educational or vocational programs. Boot camps serve as an alternative to traditional, long-term incarceration and attempt to train offenderst...

• Great Depression in the United States - U.

  prices would continue to rise and they could soon sell their stocks at a profit. The widespread belief that anyone could get rich led many less affluent Americans into the market as well. Investors bought millions of shares of stock “on margin,” arisky practice similar to buying products on credit. They paid only a small part of the price and borrowed the rest, gambling that they could sell the stock at a highenough price to repay the loan and make a profit. For a time this was true: In 1928 the...

• Electoral College.

  III HISTORY OF THE ELECTORAL COLLEGE A Origins One thing is clear about the political theory underpinning the electoral college: The framers of the Constitution could not agree on one. From the outset, the framerswere uncertain about how the president should be chosen. Meeting in the Constitutional Convention in Philadelphia, Pennsylvania, in 1787, the framers originally decidedto have Congress choose the president, and that there should be no popular vote to elect the president. Then the Con...

• Skiing.

  Safety is very important to all skiers, and all Alpine resorts have a ski patrol. The ski patrol’s responsibility is to take care of injured skiers, to mark hazardous spots ontrails, to make sure that trails are in good condition before opening them, and, at times, to act as traffic police in congested areas. Skiers are also responsible for takingtheir own safety into consideration, as well as that of others. Anyone who participates in the sport should be aware of the Skier’s Responsibility Code...

• Automobile Racing.

  beginning in 1906 at Le Mans it came to refer to the principal F1 auto race in a given nation, except in the United States, where the term continues to be used lessdiscriminately. After the end of World War I in 1918, when automobile racing blossomed internationally, a series of GP races in several nations became reserved for F1competition, and an annual GP calendar was developed consisting of national races, such as the French Grand Prix and the British Grand Prix. An annual award calledthe Wor...

Transfers occurred in apiecemeal way, but no consistent removal program developed u...

• Cosmology - astronomy.

  In 1917 American scientist Harlow Shapley measured the distance to several groups of stars known as globular clusters. He measured these distances by using amethod developed in 1912 by American astronomer Henrietta Leavitt. Leavitt’s method relates distance to variations in brightness of Cepheid variables, a class of starsthat vary periodically in brightness. Shapley’s distance measurements showed that the clusters were centered around a point far from the Sun. The arrangement of theclusters was...

  whether the leave to appeal will be granted and the case heard by the Court. The Court has no specified criteria by which it determines whether to grant leave, and the Court does not give reasons for its decision. The key factor appears to be acase’s degree of national importance. Other factors might include the impact of uncertainty in the challenged law, the case’s appropriateness for developing the law torespond to changing social needs, and the presence of a split decision at the court of ap...

For publichousing, the state government built a number of high-rise apartment blocks in run-down inner suburbs after World War II (1939-1945). These housing projects weresoon deemed unsuccessful and were discontinued because they fostered crime and other social problems. More recently, public housing has taken the form of separateor semidetached ho...

• Television.

  A charge-coupled device (CCD) can be much smaller than a camera tube and is much more durable. As a result, cameras with CCDs are more compact and portablethan those using a camera tube. The image they create is less vulnerable to distortion and is therefore clearer. In a CCD, the light from a scene strikes an array ofphotodiodes arranged on a silicon chip. Photodiodes are devices that conduct electricity when they are struck by light; they send this electricity to tiny capacitors. Thecapacitors...

• Mammal - biology.

  On land, mammals live in many different habitats, and at a wide range of altitudes. Many mammals dig burrows as refuges or as places to raise their young, but somehave developed a largely subterranean lifestyle, feeding on small animals or plant roots beneath the soil's surface. These animals, including moles and mole-rats, digthrough the ground either with spadelike front paws or with their teeth, and they detect danger by being highly sensitive to vibrations transmitted through the soil.Most m...

• Culture.

  form of knowledge, such as scientific discoveries; objects, such as works of art; and traditions, such as the observance of holidays. C1 Ethnocentrism and Cultural Relativism Self-identity usually depends on culture to such a great extent that immersion in a very different culture—with which a person does not share common ways of life orbeliefs—can cause a feeling of confusion and disorientation. Anthropologists refer to this phenomenon as culture shock. In multicultural societies —societies s...

Later he turns to the consideration of the exercise of taste in judgments of works of art,developing an elaborate theory of such judgments, but declaring that judgments of beauty made about works of artare inevitably 'impure', because the judge is implicitly aware that the the object was made . Kant's argument for the impurity of such judgments is elliptical. It turns on his conviction that a pure judgment of taste does not involve theapplication of a predicate conce...

Nevertheless, Russia managed to keep theMir space station continuously staffed wit...

• Johnson Wins Olympic Gold.

  Johnson rewarded himself with a solid jump but faltered a bit on his fourth step. Fredericks took full advantage, grabbing an early lead. Johnson recovered, firstpassing Boldon and then, at the 80-meter mark, overtaking the Namibian. A twinge of pain shot through Johnson's right hamstring as he neared the tape (the injury would keep him out of the 4 x 400 relay), but by then victory was secured.He erased the final 100 meters in a blazing 9.2 seconds, leaning into the tape a comfortable 5 met...

  In 1885, a young boy and his mother arrived at Pasteur’s laboratory; the boy had been bitten badly by a rabid dog, and Pasteur was urged to treat him with his newmethod. At the end of the treatment, which lasted ten days, the boy was being inoculated with the most potent rabies virus known; he recovered and remainedhealthy. Since that time, thousands of people have been saved from rabies by this treatment. Pasteur’s research on rabies resulted, in 1888, in the founding of a special institute in...

  Halloween traditions in southern colonies such as Virginia and Maryland. Irish immigrants helped popularize Halloween traditions throughout the United States in themid-19th century. As belief in many of the old superstitions waned during the late 19th century, Halloween was increasingly regarded as a children’s holiday. In the 19th and early 20th centuries, young people often observed Halloween by perpetrating minor acts of vandalism, such as overturning sheds or breaking windows.Beginning in th...

• Debating Sports Records Mark Purdy, sports columnist for the San Jose Mercury News in California, compiles a list of sports records that he believes will never be broken and a separate list of records that he thinks are soon to be eclipsed.

  UCLA’s dominance of NCAA men’s college basketball in the late 1960s and early 1970s will never be matched. With John Wooden as coach, the Bruins went from1967 to 1973 without losing a tournament game. Wooden built a dynasty around a system that stressed team play and solid defense, anchored by standout centersLew Alcindor (who later changed his name to Kareem Abdul-Jabbar) and Bill Walton.

• Joyner-Kersee Wins Heptathlon.

  With her knee throbbing once again, Joyner-Kersee taped up for the javelin throw. Her toss of 45.35 m (149 ft 9.5 in) was about 3 m (10 ft) short of her personalaverage, dropping her another 86 points off of the record pace. “It was disgusting,” she told Sports Illustrated. ”The knee was sore. I wasn't using the legs. I was just arming it.” One event remained: the 800 meters, the most demanding of the heptathlon's seven tests. It was also the event that had cost Joyner-Kersee the gold meda...

• Chromosome.

  chromosome breaks off and attaches to another chromosome. A translocation involving chromosomes 9 and 22 is linked to a type of leukemia called chronic myelogenicleukemia. On the sex chromosomes, problems arise in men when an abnormal gene is present on the X chromosome. With no healthy gene found on the Y chromosometo override the abnormal gene, disease may result. For example, men who inherit a mutated gene that causes hemophilia from their mother on the X chromosome willdevelop this bleeding...

  both of which built fur trading posts near present-day Edmonton in 1795. The posts were rebuilt several times, always along the North Saskatchewan River, whichprovided the traders’ main transportation route. The last move came in 1830, when Fort Edmonton was erected on the high bluff where the Alberta Legislature nowstands. For the next 50 years, the fort was the major trading center on the western plains. The modern city began to take shape after 1900, when central Alberta was opened to Europea...

Both the idea of using logic as an underlying representation language for artificial intelligence and the emphasis on formalizing common-sense knowledge are present even in McCarthy's very early work (for example, McCarthy 1959 ), but the project receives its clearest articulation in a paper jointly authored by McCarthy and Patrick Hayes (1969 )...

  computer. Since there is only one token in the network, only one computer can transmit information at a time. Token Ring networks are now quite rare. Most LANs nowuse Ethernet technology. International Business Machines Corporation (IBM), the company that invented Token Ring in the early 1980s, no longer promotes thetechnology. In the mid-1990s a new protocol called Asynchronous Transfer Mode (ATM) was introduced. This protocol encodes data in fixed-sized packets called cells rather thanvariable...

  B Movement Toward Repeal In the late 1920s, however, more and more Americans found the idea of repeal increasingly attractive. The reasons for this were numerous and complex, thegovernment’s failure to enforce the law being only one of them.
