Kallikaks Ggrandson
''The Kallikak Family: A Study in the Heredity of Feeble-Mindedness'' was a 1912 book by the American psychologist and eugenicist Henry H. Goddard, dedicated to his patron Samuel Simeon Fels. Supposedly an extended case study of Goddard’s for the inheritance of "feeble-mindedness", a general category referring to a variety of mental disabilities including intellectual disability, learning disabilities, and mental illness, the book is noted for factual inaccuracies that render its conclusions invalid. Goddard believed that a variety of mental traits were hereditary and that society should limit reproduction by people possessing these traits. The name Kallikak is a pseudonym used as a family name throughout the book. Goddard coined the name from the Greek words καλός (''kallos'') meaning good and κακός (''kakos'') meaning bad. Summary The book begins by discussing the case of "Deborah Kallikak" (real name Emma Wolverton, 1889–1978),J. David Smith and Michael L. ...

Hereditary
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents. Through heredity, variations between individuals can accumulate and cause species to evolve by natural selection. The study of heredity in biology is genetics. Overview In humans, eye color is an example of an inherited characteristic: an individual might inherit the "brown-eye trait" from one of the parents. Inherited traits are controlled by genes and the complete set of genes within an organism's genome is called its genotype. The complete set of observable traits of the structure and behavior of an organism is called its phenotype. These traits arise from the interaction of its genotype with the environment. As a result, many aspects of an organism's phenotype are not inherited. For example, suntanned skin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Halftones
Halftone is the reprographic technique that simulates continuous-tone imagery through the use of dots, varying either in size or in spacing, thus generating a gradient-like effect.Campbell, Alastair. The Designer's Lexicon. ©2000 Chronicle, San Francisco. "Halftone" can also be used to refer specifically to the image that is produced by this process. Where continuous-tone imagery contains an infinite range of colors or greys, the halftone process reduces visual reproductions to an image that is printed with only one color of ink, in dots of differing size ( pulse-width modulation) or spacing (frequency modulation) or both. This reproduction relies on a basic optical illusion: when the halftone dots are small, the human eye interprets the patterned areas as if they were smooth tones. At a microscopic level, developed black-and-white photographic film also consists of only two colors, and not an infinite range of continuous tones. For details, see film grain. Just as color ph ...

Stephen Jay Gould
Stephen Jay Gould (; September 10, 1941 – May 20, 2002) was an American paleontologist, evolutionary biologist, and historian of science. He was one of the most influential and widely read authors of popular science of his generation. Gould spent most of his career teaching at Harvard University and working at the American Museum of Natural History in New York. In 1996, Gould was hired as the Vincent Astor Visiting Research Professor of Biology at New York University, after which he divided his time teaching between there and Harvard. Gould's most significant contribution to evolutionary biology was the theory of punctuated equilibrium developed with Niles Eldredge in 1972.Eldredge, Niles, and S. J. Gould (1972)"Punctuated equilibria: an alternative to phyletic gradualism."In T.J.M. Schopf, ed., ''Models in Paleobiology''. San Francisco: Freeman, Cooper and Company, pp. 82–115. The theory proposes that most evolution is characterized by long periods of evolutionary stability, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognitive
Cognition refers to "the mental action or process of acquiring knowledge and understanding through thought, experience, and the senses". It encompasses all aspects of intellectual functions and processes such as: perception, attention, thought, intelligence, the formation of knowledge, memory and working memory, judgment and evaluation, reasoning and computation, problem solving and decision making, comprehension and production of language. Imagination is also a cognitive process, it is considered as such because it involves thinking about possibilities. Cognitive processes use existing knowledge and discover new knowledge. Cognitive processes are analyzed from different perspectives within different contexts, notably in the fields of linguistics, musicology, anesthesia, neuroscience, psychiatry, psychology, education, philosophy, anthropology, biology, systemics, logic, and computer science. These and other approaches to the analysis of cognition (such as embodied cognition) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Nervous System
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord. The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts. It is a structure composed of nervous tissue positioned along the rostral (nose end) to caudal (tail end) axis of the body and may have an enlarged section at the rostral end which is a brain. Only arthropods, cephalopods and vertebrates have a true brain (precursor structures exist in onychophorans, gastropods and lancelets). The rest of this article exclusively discusses the vertebrate central nervous system, which is radically distinct from all other animals. Overview In vertebrates, the brain and spinal cord are both enclosed in the meninges. The meninges provide a barrier to chemicals dissolv ...

Craniofacial
Craniofacial (''cranio-'' combining form meaning head or skull + ''-facial'' combining form referring to the facial structures grossly) is an adjective referring to the parts of the head enclosing the brain and the face. The term is typically used to describe an area of focus for the study and treatment of certain congenital malformations or facial injuries. The first use of the term was 1859. The first PubMed citation with the use of the term Craniofacial was in 1876 by T. H. Huxley. See also *Craniofacial Team *Craniofacial surgery Craniofacial surgery is a surgical subspecialty that deals with congenital disorder, congenital and acquired deformity, deformities of the human head, head, human skull, skull, face, neck, jaws and associated structures.

Malnutrition
Malnutrition occurs when an organism gets too few or too many nutrients, resulting in health problems. Specifically, it is "a deficiency, excess, or imbalance of energy, protein and other nutrients" which adversely affects the body's tissues and form. Malnutrition is not receiving the correct amount of nutrition. Malnutrition is increasing in children under the age of five due to providers who cannot afford or do not have access to adequate nutrition. Malnutrition is a category of diseases that includes undernutrition and overnutrition. Undernutrition is a lack of nutrients, which can result in stunted growth, wasting, and underweight. A surplus of nutrients causes overnutrition, which can result in obesity. In some developing countries, overnutrition in the form of obesity is beginning to appear within the same communities as undernutrition. Most clinical studies use the term 'malnutrition' to refer to undernutrition. However, the use of 'malnutrition' instead of 'undernutrit ...

Madison Grant
Madison Grant (November 19, 1865 – May 30, 1937) was an American lawyer, zoologist, anthropologist, and writer known primarily for his work as a eugenicist and conservationist, and as an advocate of scientific racism. Grant is less noted for his far-reaching deeds in conservation than for his advocacy of Nordicism, a form of racism which views the "Nordic race" as superior. As a eugenicist, Grant was the author of ''The Passing of the Great Race'' (1916), one of the most famous racist texts, and played an active role in crafting immigration restriction and anti-miscegenation laws in the United States. As a conservationist, he is credited with the saving of species including the American bison, helped create the Bronx Zoo, Glacier National Park, and Denali National Park, and co-founded the Save the Redwoods League. Grant developed much of the discipline of wildlife management. Early life Grant was born in New York City, New York, the son of Gabriel Grant, a physician an ...
