People From Spencer, Massachusetts
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Hawaiian Sugar Planters' Association
Founded in 1895, the Hawaiian Sugar Planters' Association (HSPA) was an unincorporated, voluntary organization of sugarcane plantation owners in the Hawaiian Islands. Its objective was to promote the mutual benefits of its members and the development of the sugar industry in the islands. It conducted scientific studies and gathered accurate records about the sugar industry. The HSPA practiced paternalistic management. Plantation owners introduced welfare programs, sometimes out of concern for the workers, but often designed to suit their economic ends. Threats, coercion, and "divide and rule" tactics were employed, particularly to keep the plantation workers ethnically segregated. The HSPA also actively campaigned to bring workers to Hawaii. For instance, they opened offices in Manila and Vigan, Ilocos Sur, to recruit Filipino workers and provide them free passage to Hawaii. Similarly, the HSPA became a powerful organization with tentacles reaching as far as Washington, D.C., where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mendelian Inheritance
Mendelian inheritance (also known as Mendelism) is a type of biological inheritance following the principles originally proposed by Gregor Mendel in 1865 and 1866, re-discovered in 1900 by Hugo de Vries and Carl Correns, and later popularized by William Bateson. These principles were initially controversial. When Mendel's theories were integrated with the Boveri–Sutton chromosome theory of inheritance by Thomas Hunt Morgan in 1915, they became the core of classical genetics. Ronald Fisher combined these ideas with the theory of natural selection in his 1930 book ''The Genetical Theory of Natural Selection'', putting evolution onto a mathematical footing and forming the basis for population genetics within the modern evolutionary synthesis. History The principles of Mendelian inheritance were named for and first derived by Gregor Johann Mendel, a nineteenth-century Moravian monk who formulated his ideas after conducting simple hybridisation experiments with pea plants (' ...
