Expert reaction: From Where Does Alcatraz Come And Can We Stop It?

Описание

An expert is somebody who has a broad and deep competence in terms of knowledge, skill and experience through practice and education in a particular field. Informally, an expert is someone widely recognized as a reliable source of technique or skill whose faculty for judging or deciding rightly, justly, or wisely is accorded authority and status by peers or the public in a specific well-distinguished domain. An expert, more generally, is a person with extensive knowledge or ability based on research, experience, or occupation and in a particular area of study. Experts are called in for advice on their respective subject, but they do not always agree on the particulars of a field of study. An expert can be believed, by virtue of credentials, training, education, profession, publication or experience, to have special knowledge of a subject beyond that of the average person, sufficient that others may officially (and legally) rely upon the individual's opinion on that topic. Historically, an expert was referred to as a sage. The individual was usually a profound thinker distinguished for wisdom and sound judgment. In specific fields, the definition of expert is well established by consensus and therefore it is not always necessary for individuals to have a professional or academic qualification for them to be accepted as an expert. In this respect, a shepherd with 50 years of experience tending flocks would be widely recognized as having complete expertise in the use and training of sheep dogs and the care of sheep. Another example from computer science is that an expert system may be taught by a human and thereafter considered an expert, often outperforming human beings at particular tasks. In law, an expert witness must be recognized by argument and authority. Research in this area attempts to understand the relation between expert knowledge, skills and personal characteristics and exceptional performance. Some researchers have investigated the cognitive structures and processes of experts. The fundamental aim of this research is to describe what it is that experts know and how they use their knowledge to achieve performance that most people assume requires extreme or extraordinary ability. Studies have investigated the factors that enable experts to be fast and accurate.Reaction may refer to a process or to a response to an action, event, or exposure:Alcatraz Island (, Latin-American Spanish pronunciation: [alkaˈtɾas], European Spanish pronunciation: [alkaˈtɾaθ] from Arabic: الْغَطَّاس‎, romanized: al-ḡaṭṭās, lit. 'gannet ("the diver")') is located in San Francisco Bay, 1.25 miles (2.01 km) offshore from San Francisco, California, United States. The small island was developed with facilities for a lighthouse, a military fortification, a military prison, and a federal prison, the latter operated from August 11, 1934 until March 21, 1963. The strong currents around the island and cold water temperatures made escape all but impossible. Since the late 20th century, it has become a major tourist attraction. Beginning in November 1969, the island was occupied for more than 19 months by a group of Native Americans, initially primarily from San Francisco, who were later joined by AIM and other urban Indians from other parts of the country, who were part of a wave of Native American activists organizing public protests across the US through the 1970s. In 1972, Alcatraz was transferred to the Department of Interior to become part of Golden Gate National Recreation Area. It was designated as a National Historic Landmark in 1986. Today, the island's facilities are managed by the National Park Service as part of Golden Gate National Recreation Area. Visitors can reach the island in fewer than 15 minutes by ferry ride from Pier 33, located between the San Francisco Ferry Building and Fisherman's Wharf, San Francisco. Hornblower Cruises, operating under the name Alcatraz Cruises, is the official ferry provider to and from the island. Alcatraz Island is the site of the abandoned federal prison, the oldest operating lighthouse on the West Coast of the United States, early military fortifications, and natural features such as rock pools and a seabird colony (mostly western gulls, cormorants, and egrets). According to a 1971 documentary on the history of Alcatraz, the island measures 1,675 feet (511 m) by 590 feet (180 m) and is 135 feet (41 m) at highest point during mean tide. The total area of the island is reported to be 22 acres (8.9 ha).Landmarks on the island include the Main Cellhouse, Dining Hall, Lighthouse, the ruins of the Warden's House and Social Hall, Parade Grounds, Building 64, Water Tower, New Industries Building, Model Industries Building, and the Recreation Yard.
