Here is a question about this article: Jean Macfarlane founded the University of California, Berkeley's Institute of Human Development, formerly called the Institute of Child Welfare, in 1927. The Institute was instrumental in initiating studies of healthy development, in contrast to previous work that had been dominated by theories based on pathological personalities. The studies looked at human development during the Great Depression and World War II, unique historical circumstances under which a generation of children grew up. The Oakland Growth Study, initiated by Harold Jones and Herbert Stolz in 1931, aimed to study the physical, intellectual, and social development of children in the Oakland area. Data collection began in 1932 and continued until 1981, allowing the researchers to gather longitudinal data on the individuals that extended past adolescence into adulthood. Jean Macfarlane launched the Berkeley Guidance Study, which examined the development of children in terms of their socioeconomic and family backgrounds. These studies provided the background for Glen Elder in the 1960s, to propose a life-course perspective of adolescent development. Elder formulated several descriptive principles of adolescent development. The principle of historical time and place states that an individual's development is shaped by the period and location in which they grow up. The principle of the importance of timing in one's life refers to the different impact that life events have on development based on when in one's life they occur. The idea of linked lives states that one's development is shaped by the interconnected network of relationships of which one is a part; and the principle of human agency asserts that one's life course is constructed via the choices and actions of an individual within the context of their historical period and social network.

Here is a question about this article: The original services of an inn are now also available at other establishments, such as hotels, lodges, and motels, which focus more on lodging customers than on other services, although they usually provide meals; pubs, which are primarily alcohol-serving establishments; and restaurants and taverns, which serve food and drink. In North America, the lodging aspect of the word "inn" lives on in hotel brand names like Holiday Inn, and in some state laws that refer to lodging operators as innkeepers.

Here is a question about this article: The Paris department store had its roots in the magasin de nouveautés, or novelty store; the first, the Tapis Rouge, was created in 1784. They flourished in the early 19th century, with La Belle Jardiniere (1824), Aux Trois Quartiers (1829), and Le Petit Saint Thomas (1830). Balzac described their functioning in his novel César Birotteau. In the 1840s, with the arrival of the railroads in Paris and the increased number of shoppers they brought, they grew in size, and began to have large plate glass display windows, fixed prices and price tags, and advertising in newspapers.
