Graphical user interface
The graphical user interface is a form of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, instead of text-based user interfaces, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces, which require commands to be typed on a computer keyboard; the actions in a GUI are performed through direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices and smaller household and industrial controls; the term GUI tends not to be applied to other lower-display resolution types of interfaces, such as video games, or not including flat screens, like volumetric displays because the term is restricted to the scope of two-dimensional display screens able to describe generic information, in the tradition of the computer science research at the Xerox Palo Alto Research Center.
Designing the visual composition and temporal behavior of a GUI is an important part of software application programming in the area of human–computer interaction. Its goal is to enhance the efficiency and ease of use for the underlying logical design of a stored program, a design discipline named usability. Methods of user-centered design are used to ensure that the visual language introduced in the design is well-tailored to the tasks; the visible graphical interface features of an application are sometimes referred to as chrome or GUI. Users interact with information by manipulating visual widgets that allow for interactions appropriate to the kind of data they hold; the widgets of a well-designed interface are selected to support the actions necessary to achieve the goals of users. A model–view–controller allows flexible structures in which the interface is independent from and indirectly linked to application functions, so the GUI can be customized easily; this allows users to select or design a different skin at will, eases the designer's work to change the interface as user needs evolve.
Good user interface design relates to users more, to system architecture less. Large widgets, such as windows provide a frame or container for the main presentation content such as a web page, email message or drawing. Smaller ones act as a user-input tool. A GUI may be designed for the requirements of a vertical market as application-specific graphical user interfaces. Examples include automated teller machines, point of sale touchscreens at restaurants, self-service checkouts used in a retail store, airline self-ticketing and check-in, information kiosks in a public space, like a train station or a museum, monitors or control screens in an embedded industrial application which employ a real-time operating system. By the 1980s, cell phones and handheld game systems employed application specific touchscreen GUIs. Newer automobiles use GUIs in their navigation systems and multimedia centers, or navigation multimedia center combinations. Sample graphical desktop environments A GUI uses a combination of technologies and devices to provide a platform that users can interact with, for the tasks of gathering and producing information.
A series of elements conforming a visual language have evolved to represent information stored in computers. This makes it easier for people with few computer skills to use computer software; the most common combination of such elements in GUIs is the windows, menus, pointer paradigm in personal computers. The WIMP style of interaction uses a virtual input device to represent the position of a pointing device, most a mouse, presents information organized in windows and represented with icons. Available commands are compiled together in menus, actions are performed making gestures with the pointing device. A window manager facilitates the interactions between windows and the windowing system; the windowing system handles hardware devices such as pointing devices, graphics hardware, positioning of the pointer. In personal computers, all these elements are modeled through a desktop metaphor to produce a simulation called a desktop environment in which the display represents a desktop, on which documents and folders of documents can be placed.
Window managers and other software combine to simulate the desktop environment with varying degrees of realism. Smaller mobile devices such as personal digital assistants and smartphones use the WIMP elements with different unifying metaphors, due to constraints in space and available input devices. Applications for which WIMP is not well suited may use newer interaction techniques, collectively termed post-WIMP user interfaces; as of 2011, some touchscreen-based operating systems such as Apple's iOS and Android use the class of GUIs named post-WIMP. These support styles of interaction using more than one finger in contact with a display, which allows actions such as pinching and rotating, which are unsupported by one pointer and mouse. Human interface devices, for the efficient interaction with a GUI include a computer keyboard used together with keyboard shortcuts, pointing devices for the cursor control: mouse, pointing stick, trackball, virtual keyboards, head-up displays. There are actions performed by programs that affect the GUI.
For example, there are components like inotify or D-Bus to facilitate communication between computer programs. Ivan Sutherland developed Sketchpad in 1963 held as the first graphical co
North America is a continent within the Northern Hemisphere and all within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, to the southeast by South America and the Caribbean Sea. North America covers an area of about 24,709,000 square kilometers, about 16.5% of the earth's land area and about 4.8% of its total surface. North America is the third largest continent by area, following Asia and Africa, the fourth by population after Asia and Europe. In 2013, its population was estimated at nearly 579 million people in 23 independent states, or about 7.5% of the world's population, if nearby islands are included. North America was reached by its first human populations during the last glacial period, via crossing the Bering land bridge 40,000 to 17,000 years ago; the so-called Paleo-Indian period is taken to have lasted until about 10,000 years ago. The Classic stage spans the 6th to 13th centuries.
The Pre-Columbian era ended in 1492, the transatlantic migrations—the arrival of European settlers during the Age of Discovery and the Early Modern period. Present-day cultural and ethnic patterns reflect interactions between European colonists, indigenous peoples, African slaves and their descendants. Owing to the European colonization of the Americas, most North Americans speak English, Spanish or French, their culture reflects Western traditions; the Americas are accepted as having been named after the Italian explorer Amerigo Vespucci by the German cartographers Martin Waldseemüller and Matthias Ringmann. Vespucci, who explored South America between 1497 and 1502, was the first European to suggest that the Americas were not the East Indies, but a different landmass unknown by Europeans. In 1507, Waldseemüller produced a world map, in which he placed the word "America" on the continent of South America, in the middle of what is today Brazil, he explained the rationale for the name in the accompanying book Cosmographiae Introductio:... ab Americo inventore... quasi Americi terram sive Americam.
For Waldseemüller, no one should object to the naming of the land after its discoverer. He used the Latinized version of Vespucci's name, but in its feminine form "America", following the examples of "Europa", "Asia" and "Africa". Other mapmakers extended the name America to the northern continent, In 1538, Gerard Mercator used America on his map of the world for all the Western Hemisphere; some argue that because the convention is to use the surname for naming discoveries, the derivation from "Amerigo Vespucci" could be put in question. In 1874, Thomas Belt proposed a derivation from the Amerrique mountains of Central America. Marcou corresponded with Augustus Le Plongeon, who wrote: "The name AMERICA or AMERRIQUE in the Mayan language means, a country of perpetually strong wind, or the Land of the Wind, and... the can mean... a spirit that breathes, life itself." The United Nations formally recognizes "North America" as comprising three areas: Northern America, Central America, The Caribbean.
This has been formally defined by the UN Statistics Division. The term North America maintains various definitions in accordance with context. In Canadian English, North America refers to the land mass as a whole consisting of Mexico, the United States, Canada, although it is ambiguous which other countries are included, is defined by context. In the United States of America, usage of the term may refer only to Canada and the US, sometimes includes Greenland and Mexico, as well as offshore islands. In France, Portugal, Romania and the countries of Latin America, the cognates of North America designate a subcontinent of the Americas comprising Canada, the United States, Mexico, Greenland, Saint Pierre et Miquelon, Bermuda. North America has been referred to by other names. Spanish North America was referred to as Northern America, this was the first official name given to Mexico. Geographically the North American continent has many subregions; these include cultural and geographic regions. Economic regions included those formed by trade blocs, such as the North American Trade Agreement bloc and Central American Trade Agreement.
Linguistically and culturally, the continent could be divided into Latin America. Anglo-America includes most of Northern America and Caribbean islands with English-speaking populations; the southern North American continent is composed of two regions. These are the Caribbean; the north of the continent maintains recognized regions as well. In contrast to the common definition of "North America", which encompasses the whole continent, the term "North America" is sometimes used to refer only to Mexico, the United States, Greenland; the term Northern America refers to the northern-most countries and territories of North America: the United States, Bermuda, St. Pierre and Miquelon and Greenland. Although the term does not refer to a unifie
Spartanburg, South Carolina
Spartanburg is the most populous city in and the seat of Spartanburg County, South Carolina, United States, the 12th-largest city by population in the state. The city of Spartanburg has a municipal population of 37,013, Spartanburg County has an urban population of 180,786 as of the 2010 census; the Spartanburg Metropolitan Statistical Area, including Spartanburg and Union counties, had a population of 317,057 as of the 2010-2014 American Community Survey 5-Year Estimates. Spartanburg is the second-largest city in the greater Greenville–Spartanburg–Anderson Combined Statistical Area, which has a population of 1,385,045 as of 2014, it is part of a 10-county region of northwestern South Carolina known as "The Upstate," and is located 98 miles northwest of Columbia, 80 miles west of Charlotte, North Carolina, about 190 miles northeast of Atlanta, Georgia. Spartanburg is a major city in South Carolina, it is the site of headquarters for Denny's. Spartanburg is home of the BMW Spartanburg factory.
Spartanburg was formed in 1785 and was named after a local militia called the Spartan Regiment in the American Revolutionary War. The Spartan Regiment, commanded by Andrew Pickens, participated in the nearby Battle of Cowpens. In 1831, Spartanburg was incorporated becoming known as the "Hub City": railroad lines radiated from the city forming the shape of a wheel hub, it became a center of textile manufacturing in the late 19th century, with around 40 textile mills being established through the early 1900s. During World War I Camp Wadsworth was used to train 100,000 soldiers for the war. Camp Croft trained soldiers during World War II; the facility was adapted as Croft State Park. By the 1950s, the production in these mills began to decline. Most textile manufacturing jobs were moved offshore by the companies. According to the United States Census Bureau, the city has a total area of 19.2 square miles, of which 19.1 square miles is land and 0.1 square miles, or 0.47%, is water. The city of Spartanburg has a humid subtropical climate with long and humid summers, cool to semi mild winters.
The average annual temperature is 61.6 °F. In the summer season from June through September, average highs are in the 80's to low 90's F, while in the winter months average highs are in the mid 50's F. Annual rainfall is spread evenly throughout the whole year. Spartanburg sees little snowfall, with the annual average being only 1.4 inches. Average precipitation is 51.3 inches and the average growing season is 231 days. Lawson's Fork Creek, a tributary of the Pacolet River, was once known for its plentiful wildlife and crystal clear waters. Parks and woodlands line much of its banks, rocky shoals and natural waterfalls can be found throughout its course, it stretches from the northern end of the county to the eastern end, where it empties into the Pacolet. The Cottonwood Trail is a walking trail located in the Edwin M. Griffin Nature Preserve that runs along part of Lawson's Fork Creek; the trail includes picnic areas, a raised path over an extensive wetlands area and access to sporadic sandbars.
Located just east of downtown, it is used by cyclists and walkers. Since the Lawson's Fork floodplain is not suitable for development, wildlife populate the area. Larger animals that can be found here include white-tailed deer, wild turkeys, pileated woodpeckers, mallard ducks, Canada geese and snapping turtles. Hatcher Garden and Woodland Preserve, is a preserve located in the midst of an urban environment. Retired social activist Harold Hatcher and his wife Josephine transformed an eroding gully into a thick woods and flower garden which now provides a haven for birds and other wildlife. Early European settlers to this area included French fur trappers, English woodsmen, Scots-Irish farmers. Few remnants survive from these early pioneering days, but traces can be found in the more rural areas of the county. Walnut Grove Plantation, an 18th-century farmhouse, has been preserved by The Spartanburg County Historical Association; the site of a locally famous skirmish during the American Revolutionary War, it was the home of the Moore family.
The plantation lies south of Spartanburg near the town of Roebuck, is open to the public for tours and during annual festivals. The Seay House, another 18th-century home, is a more typical representative of a pioneer home, its single stone fireplace and simple construction were common traits of farmsteads from this period. The Price House, the third 18th-century home maintained by the Historical Association, is unique, its sturdy Flemish-bond brick construction and three stories are less common in this area. By examining the original inventory lists of the house, the Historical Association has been able to retrieve period pieces that approximate the original contents of the house. First established in the 1780s as a courthouse village, Spartanburg may have been named for the Spartan regiment of the South Carolina militia; the city was incorporated in 1831, at the time of the 50th anniversary of the Battle of Cowpens, a pivotal fight of the American Revolution that took place only a few miles away.
The city's streets and architectural record reflect the changes of the 20th centuries. Morgan Square, the city's primary downtown hub, is the original courthouse village, it was founded adjacent to a small spring on the western slope of a ridge, which forms the border of the Tyger and Pacolet River watersheds. The square's name derives from Daniel Morgan, the general who commanded the American forces at Cowpens. A statue of Morgan was placed in the square in 1881; the oldest
Health Insurance Portability and Accountability Act
The Health Insurance Portability and Accountability Act of 1996 was enacted by the United States Congress and signed by President Bill Clinton in 1996. It was created to modernize the flow of healthcare information, stipulate how Personally Identifiable Information maintained by the healthcare and healthcare insurance industries should be protected from fraud and theft, address limitations on healthcare insurance coverage, it has been known as the Kennedy–Kassebaum Act or Kassebaum–Kennedy Act after two of its leading sponsors. The Act consists of five Titles. Title I of HIPAA protects health insurance coverage for workers and their families when they change or lose their jobs. Title II of HIPAA, known as the Administrative Simplification provisions, requires the establishment of national standards for electronic health care transactions and national identifiers for providers, health insurance plans, employers. Title III sets guidelines for pre-tax medical spending accounts, Title IV sets guidelines for group health plans, Title V governs company-owned life insurance policies.
There are five sections to the act, known as titles. Title I of HIPAA regulates the availability and breadth of group health plans and certain individual health insurance policies, it amended the Employee Retirement Income Security Act, the Public Health Service Act, the Internal Revenue Code. Title I requires the coverage of and limits restrictions that a group health plan can place on benefits for preexisting conditions. Group health plans may refuse to provide benefits in relation to preexisting conditions for either 12 months following enrollment in the plan or 18 months in the case of late enrollment. Title I allows individuals to reduce the exclusion period by the amount of time that they have had "creditable coverage" before enrolling in the plan and after any "significant breaks" in coverage. "Creditable coverage" is defined quite broadly and includes nearly all group and individual health plans and Medicaid. A "significant break" in coverage is defined as any 63-day period without any creditable coverage.
Along with an exception, allowing employers to tie premiums or co-payments to tobacco use, or body mass index. Title I requires insurers to issue policies without exclusion to those leaving group health plans with creditable coverage exceeding 18 months, renew individual policies for as long as they are offered or provide alternatives to discontinued plans for as long as the insurer stays in the market without exclusion regardless of health condition; some health care plans are exempted from Title I requirements, such as long-term health plans and limited-scope plans like dental or vision plans offered separately from the general health plan. However, if such benefits are part of the general health plan HIPAA still applies to such benefits. For example, if the new plan offers dental benefits it must count creditable continuous coverage under the old health plan towards any of its exclusion periods for dental benefits. An alternate method of calculating creditable continuous coverage is available to the health plan under Title I.
That is, 5 categories of health coverage can be considered separately, including dental and vision coverage. Anything not under those 5 categories must use the general calculation. Since limited-coverage plans are exempt from HIPAA requirements, the odd case exists in which the applicant to a general group health plan cannot obtain certificates of creditable continuous coverage for independent limited-scope plans, such as dental to apply towards exclusion periods of the new plan that does include those coverages. Hidden exclusion periods are not valid under Title I; such clauses must not be acted upon by the health plan. They must be re-written so they can comply with HIPAA. Title II of HIPAA establishes policies and procedures for maintaining the privacy and the security of individually identifiable health information, outlines numerous offenses relating to health care, establishes civil and criminal penalties for violations, it creates several programs to control fraud and abuse within the health-care system.
However, the most significant provisions of Title II are its Administrative Simplification rules. Title II requires the Department of Health and Human Services to increase the efficiency of the health-care system by creating standards for the use and dissemination of health-care information; these rules apply to "covered entities", as defined by HIPAA and the HHS. Covered entities include health plans, health care clearinghouses, health care providers that transmit health care data in a way regulated by HIPAA. Per the requirements of Title II, the HHS has promulgated five rules regarding Administrative Simplification: the Privacy Rule, the Transactions and Code Sets Rule, the Security Rule, the Unique Identifiers Rule, the Enforcement Rule; the HIPAA Privacy Rule is composed of national regulations for the use and disclosure of Protected Health Information in healthcare treatment and operations by covered entities. The effective compliance date of the Privacy Rule was April 14, 2003, with a one-year extension for certain "small plans".
The HIPAA Privacy Rule regulates the use and disclosure of protected health information held by "covered entitie
