Adverse Childhood Experiences
Adverse childhood experiences (ACEs) encompass various forms of physical and emotional abuse, neglect, and household dysfunction experienced in childhood. The harms of ACEs can be long-lasting, affecting people even in their adulthood. ACEs have been linked to premature death as well as to various health conditions, including those of mental disorders. Toxic stress linked to child abuse is related to a number of neurological changes in the structure of the brain and its function. Definition and types The concept of adverse childhood experiences refers to various traumatic events or circumstances affecting children before the age of 18 and causing mental or physical harm. There are 10 types of ACEs: * physical abuse * sexual abuse * psychological abuse * physical neglect * psychological neglect * witnessing domestic abuse * having a close family member who misused drugs or alcohol * having a close family member with mental health problems * having a close family member wh ...

Physical Abuse
Physical abuse is any intentional act causing injury or trauma to another person or animal by way of bodily contact. In most cases, children are the victims of physical abuse, but adults can also be victims, as in cases of domestic violence or workplace aggression. Alternative terms sometimes used include physical assault or physical violence, and may also include sexual abuse. Physical abuse may involve more than one abuser, and more than one victim. Forms Physical abuse means any non-accidental act or behavior causing injury, trauma, or other physical suffering or bodily harm. Abusive acts toward children can often result from parents' attempts at child discipline through excessive corporal punishment."Child physical abuse". American Hum ...

Poverty
Poverty is the state of having few material possessions or little income. Poverty can have diverse social, economic, and political causes and effects. When evaluating poverty in statistics or economics there are two main measures: ''absolute poverty'' compares income against the amount needed to meet basic needs, basic personal needs, such as food, clothing, and Shelter (building), shelter; ''relative poverty'' measures when a person cannot meet a minimum level of living standards, compared to others in the same time and place. The definition of ''relative poverty'' varies from one country to another, or from one society to another. Statistically, , most of the world's population live in poverty: in Purchasing Power Parity, PPP dollars, 85% of people live on less than $30 per day, two-thirds live on less than $10 per day, and 10% live on less than $1.90 per day ...

Dose–response Relationship
The dose–response relationship, or exposure–response relationship, describes the magnitude of the response of an organism, as a function of exposure (or doses) to a stimulus or stressor (usually a chemical) after a certain exposure time. Dose–response relationships can be described by dose–response curves. This is explained further in the following sections. A stimulus response function or stimulus response curve is defined more broadly as the response from any type of stimulus, not limited to chemicals. Motivation for studying dose–response relationships Studying dose response, and developing dose–response models, is central to determining "safe", "hazardous" and (where relevant) beneficial levels and dosages for drugs, pollutants, foods, and other substances to which humans or other organisms are exposed. These conclusions are often the basis for public policy. The U.S. Environmental Protection Agency has developed extensive guidance and reports on dose–respon ...

Glucocorticoid Receptors
Steroid hormone receptors are found in the nucleus, cytosol, and also on the plasma membrane of target cells. They are generally intracellular receptors (typically cytoplasmic or nuclear) and initiate signal transduction for steroid hormones which lead to changes in gene expression over a time period of hours to days. The best studied steroid hormone receptors are members of the nuclear receptor subfamily 3 (NR3) that include receptors for estrogen (group NR3A) and 3-ketosteroids (group NR3C). In addition to nuclear receptors, several G protein-coupled receptors and ion channels act as cell surface receptors for certain steroid hormones. Types Nuclear receptors Steroid receptors of the nuclear receptor family are all transcription factors. Depending upon the type of receptor, they are either located in the cytosol and move to the cell nucleus upon activation, or remain in the nucleus waiting for the steroid hormone to enter and activate them. This uptake into the nucleus is faci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corpus Callosum
The corpus callosum (Latin for "tough body"), also callosal commissure, is a wide, thick nerve tract, consisting of a flat bundle of commissural fibers, beneath the cerebral cortex in the brain. The corpus callosum is only found in placental mammals. It spans part of the longitudinal fissure, connecting the left and right cerebral hemispheres, enabling communication between them. It is the largest white matter structure in the human brain, about in length and consisting of 200–300 million axonal projections. A number of separate nerve tracts, classed as subregions of the corpus callosum, connect different parts of the hemispheres. The main ones are known as the genu, the rostrum, the trunk or body, and the splenium. Structure The corpus callosum forms the floor of the longitudinal fissure that separates the two cerebral hemispheres. Part of the corpus callosum forms the roof of the lateral ventricles. The corpus callosum has four main parts – individual nerve tracts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amygdala
The amygdala (; plural: amygdalae or amygdalas; also '; Latin from Greek, , ', 'almond', 'tonsil') is one of two almond-shaped clusters of nuclei located deep and medially within the temporal lobes of the brain's cerebrum in complex vertebrates, including humans. Shown to perform a primary role in the processing of memory, decision making, and emotional responses (including fear, anxiety, and aggression), the amygdalae are considered part of the limbic system. The term "amygdala" was first introduced by Karl Friedrich Burdach in 1822. Structure The regions described as amygdala nuclei encompass several structures of the cerebrum with distinct connectional and functional characteristics in humans and other animals. Among these nuclei are the basolateral complex, the cortical nucleus, the medial nucleus, the central nucleus, and the intercalated cell clusters. The basolateral complex can be further subdivided into the lateral, the basal, and the accessory basal nucle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hippocampus
The hippocampus (via Latin from Greek , 'seahorse') is a major component of the brain of humans and other vertebrates. Humans and other mammals have two hippocampi, one in each side of the brain. The hippocampus is part of the limbic system, and plays important roles in the consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation. The hippocampus is located in the allocortex, with neural projections into the neocortex in humans, as well as primates. The hippocampus, as the medial pallium, is a structure found in all vertebrates. In humans, it contains two main interlocking parts: the hippocampus proper (also called ''Ammon's horn''), and the dentate gyrus. In Alzheimer's disease (and other forms of dementia), the hippocampus is one of the first regions of the brain to suffer damage; short-term memory loss and disorientation are included among the early symptoms. Damage to the hippocampus can also result from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brain
A brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It is located in the head, usually close to the sensory organs for senses such as vision. It is the most complex organ in a vertebrate's body. In a human, the cerebral cortex contains approximately 14–16 billion neurons, and the estimated number of neurons in the cerebellum is 55–70 billion. Each neuron is connected by synapses to several thousand other neurons. These neurons typically communicate with one another by means of long fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells. Physiologically, brains exert centralized control over a body's other organs. They act on the rest of the body both by generating patterns of muscle activity and by driving the secretion of chemicals called hormones. This centralized control allows rapid and coordinated respon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recidivism
Recidivism (; from ''recidive'' and ''ism'', from Latin ''recidīvus'' "recurring", from ''re-'' "back" and ''cadō'' "I fall") is the act of a person repeating an undesirable behavior after they have experienced negative consequences of that behavior. It is also used to refer to the percentage of former prisoners who are rearrested for a similar offense.Henslin, James. ''Social Problems: A Down-To-Earth Approach'', 2008. The term is frequently used in conjunction with criminal behavior and substance abuse. Recidivism is a synonym for "relapse", which is more commonly used in medicine and in the disease model of addiction. Norway has one of the lowest recidivism rates in the world at 20%. Prisons in Norway and the Norwegian criminal justice system focus on restorative justice and rehabilitating prisoners rather than punishment. United States According to an April 2011 report by the Pew Center on the States, the average national recidivism rate for released prisoner ...

Externalization (psychology)
Psychoanalysis In Freudian psychology, externalization ( or externalisation) is a defense mechanism by which an individual projects their own internal characteristics onto the outside world, particularly onto other people. For example, a patient who is overly argumentative might instead perceive others as argumentative and themselves as blameless. Like other defense mechanisms, externalization is a protection against anxiety and is, therefore, part of a healthy, normally functioning mind. However, if taken to excess, it can lead to the development of a neurosis. Narrative therapy Michael White states that the problem of the client is externalized, to alter the client's point of view.

Internalizing
Internalization ( or internalisation) is the process of making something internal, with more specific meanings in various fields. It is the opposite of externalization. Psychology and sociology In psychology, internalization is the outcome of a conscious mind reasoning about a specific subject; the subject is internalized, and the consideration of the subject is internal. Internalization of ideals might take place following religious conversion, or in the process of, more generally, moral conversion. Internalization is directly associated with learning within an organism (or business) and recalling what has been learned. In psychology and sociology, internalization involves the integration of attitudes, values, standards and the opinions of others into one's own identity or sense of self. In psychoanalytic theory, internalization is a process involving the formation of the super ego. Many theorists believe that the internalized values of behavior implemented during early social ...

Child
A child ( : children) is a human being between the stages of birth and puberty, or between the developmental period of infancy and puberty. The legal definition of ''child'' generally refers to a minor, otherwise known as a person younger than the age of majority. Children generally have fewer rights and responsibilities than adults. They are classed as unable to make serious decisions. ''Child'' may also describe a relationship with a parent (such as sons and daughters of any age) or, metaphorically, an authority figure, or signify group membership in a clan, tribe, or religion; it can also signify being strongly affected by a specific time, place, or circumstance, as in "a child of nature" or "a child of the Sixties." Biological, legal and social definitions In the biological sciences, a child is usually defined as a person between birth and puberty, or between the developmental period of infancy and puberty. Legally, the term ''child'' may refer to anyone below th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
