Minneapolis, Minnesota
Minneapolis () is the largest city in Minnesota, United States, and the county seat of Hennepin County. The city is abundant in water, with thirteen lakes, wetlands, the Mississippi River, creeks and waterfalls. Minneapolis has its origins in timber and as the flour milling capital of the world. It occupies both banks of the Mississippi River and adjoins Saint Paul, the state capital of Minnesota. Prior to European settlement, the site of Minneapolis was inhabited by Dakota people. The settlement was founded along Saint Anthony Falls on a section of land north of Fort Snelling; its growth is attributed to its proximity to the fort and the falls providing power for industrial activity. , the city has an estimated 425,336 inhabitants.

Neuropsychiatry
Neuropsychiatry or Organic Psychiatry is a branch of medicine that deals with psychiatry as it relates to neurology, in an effort to understand and attribute behavior to the interaction of neurobiology and social psychology factors. Within neuropsychiatry, the mind is considered "as an emergent property of the brain", whereas other behavioral and neurological specialties might consider the two as separate entities. Neuropsychiatry preceded the current disciplines of psychiatry and neurology, which previously had common training, however, those disciplines have subsequently diverged and are typically practiced separately. Currently, neuropsychiatry has become a growing subspecialty of psychiatry as it closely relates the fields of neuropsychology and behavioral neurology, and attempts to utilize this understanding to better treat illnesses that fall under both neurological and mental disorder classifications (e.g., autism, ADHD, Tourette's syndrome). The case for the rapprochemen ...

Criminal Record
A criminal record, police record, or colloquially RAP sheet (Record of Arrests and Prosecutions) is a record of a person's criminal history. The information included in a criminal record and the existence of a criminal record varies between countries and even between jurisdictions within a country. In most cases it lists all non-expunged criminal offences and may also include traffic offences such as speeding and drunk driving. In some countries the record is limited to actual convictions (where the individual has pled guilty or been found guilty by a qualified court, resulting in the entry of a conviction), while in others it also includes arrests, charges dismissed, charges pending and charges of which the individual has been acquitted. A criminal history may be used by potential employers, lenders, and others to assess a person's trustworthiness. Criminal records may also be relevant for international travel, and for the charging and sentencing of persons who commit additio ...

Financial Independence
Financial independence is the status of having enough income or wealth sufficient to pay one's living expenses for the rest of one's life without having to be employed or dependent on others.Cummuta, John. The Myths & Realities of Achieving Financial Independence". Nightingale Conant. Retrieved on 14-Sep-2009 Income earned without having to work a job is commonly referred to as passive income. Others define financial independence differently according to their own goals. There are many strategies to achieve financial independence, each with their own benefits and drawbacks. Someone who wishes to achieve financial independence can find it helpful to have a financial plan and budget, so that they have a clear view of their current incomes and expenses, and can identify and choose appropriate strategies to move towards their financial goals. A financial plan addresses every aspect of a person's finances. Passive sources of income to achieve financial independence The followin ...

Married
Marriage, also called matrimony or wedlock, is a culturally and often legally recognized union between people called spouses. It establishes rights and obligations between them, as well as between them and their children, and between them and their in-laws. It is considered a cultural universal, but the definition of marriage varies between cultures and religions, and over time. Typically, it is an institution in which interpersonal relationships, usually sexual, are acknowledged or sanctioned. In some cultures, marriage is recommended or considered to be compulsory before pursuing any sexual activity. A marriage ceremony is called a wedding. Individuals may marry for several reasons, including legal, social, libidinal, emotional, financial, spiritual, and religious purposes. Whom they marry may be influenced by gender, socially determined rules of incest, prescriptive marriage rules, parental choice, and individual desire. In some areas of the world, arranged mar ...

License
A license (or licence) is an official permission or permit to do, use, or own something (as well as the document of that permission or permit). A license is granted by a party (licensor) to another party (licensee) as an element of an agreement between those parties. In the case of a license issued by a government, the license is obtained by applying for it. In the case of a private party, it is by a specific agreement, usually in writing (such as a lease or other contract). The simplest definition is "A license is a promise not to sue," because a license usually either permits the licensed party to engage in an activity which is illegal, and subject to prosecution, without the license (e.g. fishing, driving an automobile, or operating a broadcast radio or television station), or it permits the licensed party to do something that would violate the rights of the licensing party (e.g. make copies of a copyrighted work), which, without the license, the licensed party could be ...

Mainstream Science On Intelligence
"Mainstream Science on Intelligence" was a public statement issued by a group of researchers of topics associated with intelligence testing. It was published originally in ''The Wall Street Journal'' on December 13, 1994, as a response to criticism of the book ''The Bell Curve'' by Richard Herrnstein and Charles Murray, which appeared earlier the same year. The statement defended Herrnstein and Murray's controversial claims about race and intelligence. The statement was drafted by Linda Gottfredson, a professor of educational psychology at the University of Delaware. It was sent to 131 researchers whom Gottfredsen described as "experts in intelligence and allied fields". Of these, 52 signed the statement, 48 returned the request with an explicit refusal to sign, and 31 ignored the request. According to a 1996 response by former American Psychological Association president Donald Campbell, only ten of those who signed were actual experts in intelligence measurement. The Southern ...

The Bell Curve
''The Bell Curve: Intelligence and Class Structure in American Life'' is a 1994 book by psychologist Richard J. Herrnstein and political scientist Charles Murray, in which the authors argue that human intelligence is substantially influenced by both inherited and environmental factors and that it is a better predictor of many personal outcomes, including financial income, job performance, birth out of wedlock, and involvement in crime than are an individual's parental socioeconomic status. They also argue that those with high intelligence, the "cognitive elite", are becoming separated from those of average and below-average intelligence, and that this separation is a source of social division within the United States. The book was and remains highly controversial, especially where the authors discussed purported connections between race and intelligence and suggested policy implications based on these purported connections. Shortly after its publication, many people rallied bot ...

Trait (biological)
A phenotypic trait, simply trait, or character state is a distinct variant of a phenotypic characteristic of an organism; it may be either inherited or determined environmentally, but typically occurs as a combination of the two.Lawrence, Eleanor (2005) ''Henderson's Dictionary of Biology''. Pearson, Prentice Hall. For example, having eye color is a ''character'' of an organism, while blue, brown and hazel versions of eye colour are ''traits''. The term ''trait'' is generally used in genetics, often to describe phenotypic expression of different combinations of alleles in different individual organisms within a single population, such as the famous purple vs. white flower coloration in Gregor Mendel's pea plants. By contrast, in systematics, the term is ''character state'' is employed to describe features that represent fixed diagnostic differences among taxa, such as the absence of tails in great apes, relative to other primate groups. Definition A phenotypic trait is a ...

Heritability
Heritability is a statistic used in the fields of breeding and genetics that estimates the degree of ''variation'' in a phenotypic trait in a population that is due to genetic variation between individuals in that population. The concept of heritability can be expressed in the form of the following question: "What is the proportion of the variation in a given trait within a population that is ''not'' explained by the environment or random chance?" Other causes of measured variation in a trait are characterized as environmental factors, including observational error. In human studies of heritability these are often apportioned into factors from "shared environment" and "non-shared environment" based on whether they tend to result in persons brought up in the same household being more or less similar to persons who were not. Heritability is estimated by comparing individual phenotypic variation among related individuals in a population, by examining the association between indiv ...
