Causes of Mental Disorders
A mental disorder is an impairment of the mind disrupting normal thinking, feeling, mood, behavior, or social interactions, and accompanied by significant distress or dysfunction. The causes of mental disorders are very complex and vary depending on the particular disorder and the individual. Although the causes of most mental disorders are not fully understood, researchers have identified a variety of biological, psychological, and environmental factors that can contribute to the development or progression of mental disorders. Most mental disorders result in a combination of several different factors rather than just a single factor.

Ontological Argument
Ontological is derived from ontos, the greek word being. The name is intended to convey the intent of the argument to prove God's existence by virtue of his existence being necessary. It was first proposed by the medieval philosopher Anselm of Canterbury in his Proslogion, and important variations have been developed by philosophers such as René Descartes, Gottfried Leibniz, Norman Malcolm, Charles Hartshorne, and Alvin Plantinga. A modal logic version of the argument was devised by mathematician Kurt Gödel. The ontological argument has been controversial in philosophy and many philosophers have famously criticized or opposed it, including Anselm's contemporary Gaunilo of Marmoutiers, as well as David Hume, Immanuel Kant, and Gottlob Frege. Some of these opponents have preferred to rely on cosmological arguments for the existence of God instead. It continues to garner discus ion to the present.

Duality (Mathematics)
In mathematics, a duality translates concepts, theorems or mathematical structures into other concepts, theorems or structures, in a one-to-one fashion, often (but not always) by means of an involution operation: if the dual of A is B, then the dual of B is A. Such involutions sometimes have fixed points, so that the dual of A is A itself. For example, Desargues' theorem is self-dual in this sense under the standard duality in projective geometry. In mathematical contexts, duality has numerous meanings. It has been described as "a very pervasive and important concept in (modern) mathematics" and "an important general theme that has manifestations in almost every area of mathematics". Many mathematical dualities between objects of two types correspond to pairings, bilinear functions from an object of one type and another object of the second type to some family of scalars. For instance, linear algebra duality corresponds in this way to bilinear maps from pairs of vector spaces to scalars, the duality between distributions and the associated test functions corresponds to the pairing in which one integrates a distribution against a test function, and Poincaré duality corresponds similarly to intersection number, viewed as a pairing between submanifolds of a given manifold. From a category theory viewpoint, duality can also be seen as a functor, at least in the realm of vector spaces. This functor assigns to each space its dual space, and the pullback construction assigns to each arrow f: V → W its dual f∗: W∗ → V∗.

Extractive Industries Transparency Initiative
The Extractive Industries Transparency Initiative (EITI) is a global standard for the good governance of oil, gas and mineral resources. It seeks to address the key governance issues in the extractive sectors. The EITI Standard requires information along the extractive industry value chain from the point of extraction, to how the revenue makes its way through the government and its contribution to the economy. This includes how licenses and contracts are allocated and registered, who the beneficial owners of those operations are, what the fiscal and legal arrangements are, how much is produced, how much is paid, where the revenue is allocated, and its contributions to the economy, including employment. The EITI Standard is implemented in 52 countries around the world. Each of these countries is required to publish an annual EITI Report to disclosing information on: contracts and licenses, production, revenue collection, revenue allocation, and social and economic spending. Every country goes through a quality-assurance mechanism, called Validation, at least every three years. Validation serves to assess performance towards meeting the EITI Standard and promote dialogue and learning at the country level. It also safeguards the integrity of the EITI by holding all EITI implementing countries to the same global standard. Each implementing country has its own national secretariat and multi-stakeholder group made up of representatives from the country’s government, extractive companies and civil society. The multi-stakeholder group takes decisions on how the EITI process is carried out in the country. The EITI Standard is developed and overseen by an international multi-stakeholder Board, consisting of representatives from governments, extractives companies, civil society organisations, financial institutions and international organisations. The current Chair of the EITI is Fredrik Reinfeldt, former Prime Minister of Sweden. The previous chairs have been Clare Short (2011-2016), former UK Secretary of State for International Development and Peter Eigen (2009-2011). The EITI International Secretariat is located in Oslo, Norway and is headed by Eddie Rich.

Spirit (Animating Force)
In folk belief, spirit is the vital principle or animating force within all living things. As recently as 1628 and 1633 respectively, both William Harvey and René Descartes still speculated that somewhere within the body, in a special locality, there was a "vital spirit" or "vital force", which animated the whole bodily frame, just as the engine in a factory moves the machinery in it. People have frequently conceived of spirit as a supernatural being, or non-physical entity; for example, a demon, ghost, fairy, or angel. In ancient Islamic terminology however, the term spirit (rūḥ), applies only to "pure" spirits, but not to other invisible creatures, such as jinn, demons and angels. Historically, spirit has been used to refer to a "subtle" as opposed to "gross" material substance, as put forth in the notable last paragraph of Sir Isaac Newton's Principia Mathematica. In English Bibles, "the Spirit" (with a capital "S"), specifically denotes the Holy Spirit. The concepts of spirit and soul often overlap, and some systems propose that both survive bodily death. "Spirit" can have the sense of "ghost", i.e. a manifestation of the spirit of a deceased person. "Spirit" is also often used to refer to the consciousness or personality.

Jurimetrics
Jurimetrics is the application of quantitative methods, and often especially probability and statistics, to law. In the United States, the journal Jurimetrics is published by the American Bar Association and Arizona State University. The Journal of Empirical Legal Studies is another publication that emphasizes the statistical analysis of law. The term was coined in 1949 by Lee Loevinger in his article "Jurimetrics: The Next Step Forward". Showing the influence of Oliver Wendell Holmes, Jr., Loevinger quoted Holmes' celebrated phrase that: The first work on this topic is attributed to Nicolaus I Bernoulli in his doctoral dissertation De Usu Artis Conjectandi in Jure, written in 1709.

Emotional Dysregulation
Emotional dysregulation is a term used in the mental health community that refers to emotional responses that are poorly modulated and do not lie within the accepted range of emotive response. Emotional dysregulation can be associated with an experience of early psychological trauma, brain injury, or chronic maltreatment (such as child abuse, child neglect, or institutional neglect/abuse), and associated disorders such as reactive attachment disorder. Emotional dysregulation may be present in people with psychiatric disorders such as attention deficit hyperactivity disorder, autism spectrum disorders, bipolar disorder, borderline personality disorder, complex post-traumatic stress disorder, and fetal alcohol spectrum disorders. In such cases as borderline personality disorder and complex post-traumatic stress disorder, hypersensitivity to emotional stimuli causes a slower return to a normal emotional state. This is manifested biologically by deficits in the frontal cortices of the brain. Possible manifestations of emotional dysregulation include extreme tearfulness, angry outbursts or behavioral outbursts such as destroying or throwing objects, aggression towards self or others, and threats to kill oneself. Emotional dysregulation can lead to behavioral problems and can interfere with a person's social interactions and relationships at home, in school, or at place of employment.

Risk Factors of Schizophrenia
Risk factors of schizophrenia include multiple genetic and environmental risk factors. The prevailing model of schizophrenia is that of a neurodevelopmental disorder with no precise boundary, or single cause, and is thought to develop from complex gene–environment interactions with involved vulnerability factors. The interactions of these risk factors are complicated, as numerous and diverse insults from conception to adulthood can be involved. The combination of genetic and environmental factors leads to deficits in the neural circuits that affect sensory input and cognitive functions. A genetic predisposition on its own, without interacting environmental factors, will not give rise to the development of schizophrenia. Environmental risk factors are many, and include pregnancy complications, prenatal stress and nutrition, and adverse childhood experiences. An environmental risk factor may act alone or in combination with others. Schizophrenia typically develops between the ages of 16–30 (generally males aged 16–25 years and females 25–30 years); about 75 percent of people living with the illness developed it in these age-ranges. Childhood schizophrenia that develops before the age of 13 is quite rare. There is on average a somewhat earlier onset for men than women, with the possible influence of the female sex hormone estrogen being one hypothesis and socio-cultural influences another. Estrogen is seen to have a dampening effect on dopamine receptors.

Altruism
In biology, altruism refers to behaviour by an individual that increases the fitness of another individual while decreasing the fitness of the agent. Altruism in this sense is different from the philosophical concept of altruism, in which an action would only be called "altruistic" if it was done with the conscious intention of helping another. In the behavioural sense, there is no such requirement. As such, it is not evaluated in moral terms—it is the consequences of an action for reproductive fitness that determine whether the action is considered altruistic, not the intentions, if any, with which the action is performed. The term altruism was coined by the French philosopher Auguste Comte in French, as altruisme, for an antonym of egoism. He derived it from the Italian altrui, which in turn was derived from Latin alteri, meaning "other people" or "somebody else". Altruistic behaviours appear most obviously in kin relationships, such as in parenting, but may also be evident among wider social groups, such as in social insects. They allow an individual to increase the success of its genes by helping relatives that share those genes. Obligate altruism is the permanent loss of direct fitness (with potential for indirect fitness gain). For example, honey bee workers may forage for the colony. Facultative altruism is temporary loss of direct fitness (with potential for indirect fitness gain followed by personal reproduction). For example, a Florida scrub jay may help at the nest, then gain parental territory.

Behavioral Operations Research
Behavioral operations research (BOR) examines and takes into consideration human behavior and emotions when facing complex decision problems. BOR is part of Operational Research. BOR relates to the behavioural aspects of the use of operations research in problem solving and decision support. Specifically, it focuses on understanding behaviour in, with and beyond models. The general purpose is to make better use and improve the use of operations research theories and practice, so that the benefits received from the potential improvements to operations research approaches in practice, that arise from recent findings in behavioural sciences, are realised . BOR approaches have heavily influenced supply chain management research, amongst others.
