Attention deficit hyperactivity disorder

Attention deficit hyperactivity disorder (ADHD, similar to hyperkinetic disorder in the ICD-10) is a neurodevelopmental psychiatric disorder in which there are significant problems with executive functions (e.g., attentional control and inhibitory control) that cause attention deficits, hyperactivity, or impulsiveness which is not appropriate for a person's age. These symptoms must begin by age six to twelve and persist for more than six months for a diagnosis to be made. In school-aged individuals inattention symptoms often result in poor school performance. Although it causes impairment, particularly in modern society, many children have a good attention span for tasks they find interesting.

Despite being the most commonly studied and diagnosed psychiatric disorder in children and adolescents, the cause in the majority of cases is unknown. The World Health Organization estimates that it affected about 39 million people as of 2013. It affects about 6–7% of children when diagnosed via the DSM-IV criteria and 1–2% when diagnosed via the ICD-10 criteria. Rates are similar between countries and depend mostly on how it is diagnosed. ADHD is diagnosed approximately three times more in boys than in girls. About 30–50% of people diagnosed in childhood continue to have symptoms into adulthood and between 2–5% of adults have the condition. The condition can be difficult to tell apart from other disorders as well as from high levels of activity that are still within the normal-range.

Post-office box

A post-office box or post office box (commonly referred to as a PO box or a postal box) is a uniquely addressable lockable box located on the premises of a post office station.

In many regions, particularly in Africa and the Middle East, there is no 'door to door' delivery of mail. For example, should one post mail to a street address in Namibia, it will be returned to sender as undeliverable. Consequently, renting a PO box has traditionally been the only way to receive mail in such countries, although some, like Jordan, Egypt and Lebanon, do have mail home delivery.

Generally, post office boxes are rented from the post office either by individuals or by businesses on a basis ranging from monthly to annual, and the cost of rent varies depending on the box size. Central business district (CBD) PO boxes are usually more expensive than rural PO boxes.

In the United States, the rental rate used to be uniform across the country. Now, however, a postal facility can be in any of seven fee groups by location; in addition, certain customers qualify for free box rental.

Social media

Social media are computer-mediated tools that allow people or companies to create, share, or exchange information, career interests, ideas, and pictures/videos in virtual communities and networks. Social media is defined as "a group of Internet-based applications that build on the ideological and technological foundations of Web 2.0, and that allow the creation and exchange of user-generated content." Furthermore, social media depend on mobile and web-based technologies to create highly interactive platforms through which individuals and communities share, co-create, discuss, and modify user-generated content. They introduce substantial and pervasive changes to communication between businesses, organizations, communities, and individuals. These changes are the focus of the emerging field of technoself studies. Social media differ from traditional or industrial media in many ways, including quality,reach, frequency, usability, immediacy, and permanence. Social media operate in a dialogic transmission system (many sources to many receivers). This is in contrast to traditional media that operates under a monologic transmission model (one source to many receivers).

Whittier, California

Whittier (/ˈwɪtiər/) is a city in Southern California. The city had a population of 85,331 at the 2010 census, up from 83,680 as of the 2000 census, and encompasses 14.7 square miles (38.0 km²). Like nearby Montebello, the city constitutes part of the Gateway Cities. Whittier was incorporated in February 1898 and became a charter city in 1955. The city is named for the poet John Greenleaf Whittier and is home to Whittier College.

History

Whittier's roots can be traced to Spanish soldier Manuel Nieto. In 1784, Nieto received a Spanish land grant of 300,000 acres (1,200 km²), Rancho Los Nietos, as a reward for his military service and to encourage settlement in California. The area of Nieto's land grant was reduced in 1790 as the result of a dispute with Mission San Gabriel. Nonetheless, Nieto still had claim to 167,000 acres (680 km²) stretching from the hills north of Whittier, Fullerton and Brea, south to the Pacific ocean, and from what is known today as the Los Angeles River east to the Santa Ana River. Nieto built a rancho for his family near Whittier, and purchased cattle and horses for his ranch and also planted cornfields. When Nieto died in 1804, his children inherited their father's property.
