Precommitment
In psychology, precommitment refers to a strategy or a method of self-control that an agent may use to restrict the number of choices available to them at a future time. The strategy may also involve the imposition of obstacles or additional costs to certain courses of action in advance. As theorized by the social scientist Jon Elster, agents may precommit themselves when they predict that their preferences will change but wish to ensure that their future actions will align with their current preferences. Precommitment has also been studied as a bargaining strategy in which agents bind themselves to one course of action in order to enhance the credibility of present threats. Some scholars have proposed that collective political agents may also engage in precommitment by adopting constitutions that limit the scope of future legislation. The validity of this application of precommitment theory has been called into question, however. Background In two unrelated articles, both pub ...

Commitment Device
A commitment device is, according to journalist Stephen J. Dubner and economist Steven Levitt, a way to lock oneself into following a plan of action that one might not want to do, but which one knows is good for oneself. In other words, a commitment device is a way to give oneself a reward or punishment to make an empty promise stronger and believable. A commitment device is a technique where someone makes it easier for themselves to avoid akrasia (acting against one's better judgment), particularly procrastination. Commitment devices have two major features. They are voluntarily adopted for use and they tie consequences to follow-through failures. Consequences can be immutable (irreversible, such as a monetary consequence) or mutable (allows for the possibility of future reversal of the consequence). Overview The term "commitment device" is used in both economics and game theory. In particular, the concept is relevant to the fields of economics and especially the study of deci ...

Psychology
Psychology is the scientific study of mind and behavior. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Fernald LD (2008)''Psychology: Six perspectives'' (pp.12–15). Thousand Oaks, CA: Sage Publications.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. Ψ (''psi''), the first letter of the Greek word ''psyche'' from which the term psychology is derived (see below), is commonly associated with the science. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as behavioral or cognitive scientists. Some psyc ...

Siren (mythology)
In Greek mythology, the sirens (Ancient Greek: singular: ; plural: ) were humanlike beings with alluring voices; they appear in a scene in the Odyssey in which Odysseus saves his crew's lives. Roman poets placed them on some small islands called Sirenum scopuli. In some later, rationalized traditions, the literal geography of the "flowery" island of Anthemoessa, or Anthemusa, is fixed: sometimes on Cape Pelorum and at others in the islands known as the Sirenuse, near Paestum, or in Capreae. All such locations were surrounded by cliffs and rocks. Sirens continued to be used as a symbol for the dangerous temptation embodied by women regularly throughout Christian art of the medieval era. Nomenclature The etymology of the name is contested. Robert S. P. Beekes has suggested a Pre-Greek origin. Others connect the name to σειρά (''seirá'', "rope, cord") and εἴρω (''eírō'', "to tie, join, fasten"), resulting in the meaning "binder, entangler", i.e. one who binds ...

Addiction
Addiction is a neuropsychological disorder characterized by a persistent and intense urge to engage in certain behaviors, one of which is the usage of a drug, despite substantial harm and other negative consequences. Repetitive drug use often alters brain function in ways that perpetuate craving, and weakens (but does not completely negate) self-control. This phenomenon – drugs reshaping brain function – has led to an understanding of addiction as a brain disorder with a complex variety of psychosocial as well as neurobiological (and thus involuntary) factors that are implicated in addiction's development. Classic signs of addiction include compulsive engagement in rewarding stimuli, ''preoccupation'' with substances or behavior, and continued use despite negative consequences. Habits and patterns associated with addiction are typically characterized by immediate gratification (short-term reward), coupled with delayed deleterious effects (long-term costs). Examp ...

French Literature
French literature () generally speaking, is literature written in the French language, particularly by citizens of France; it may also refer to literature written by people living in France who speak traditional languages of France other than French. Literature written in the French language, by citizens of other nations such as Belgium, Switzerland, Canada, Senegal, Tunisia, Algeria, Morocco, etc. is referred to as Francophone literature. France itself ranks first on the list of Nobel Prizes in literature by country. For centuries, French literature has been an object of national pride for French people, and it has been one of the most influential components of the literature of Europe. One of the first known examples of French literature is the Song of Roland, the first major work in a series of poems known as, " chansons de geste". The French language is a Romance language derived from Latin and heavily influenced principally by Celtic and Frankish. Beginning in the 11th ...

Supermajority
A supermajority, supra-majority, qualified majority, or special majority is a requirement for a proposal to gain a specified level of support which is greater than the threshold of more than one-half used for a simple majority. Supermajority rules in a democracy can help to prevent a majority from eroding fundamental rights of a minority, but they can also hamper efforts to respond to problems and encourage corrupt compromises in the times action is taken. Changes to constitutions, especially those with entrenched clauses, commonly require supermajority support in a legislature. Parliamentary procedure requires that any action of a deliberative assembly that may alter the rights of a minority have a supermajority requirement, such as a two-thirds vote. Related concepts regarding alternatives to the majority vote requirement include a majority of the entire membership and a majority of the fixed membership. A supermajority can also be specified based on the entire membership or f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Judiciary
The judiciary (also known as the judicial system, judicature, judicial branch, judiciative branch, and court or judiciary system) is the system of courts that adjudicates legal disputes/disagreements and interprets, defends, and applies the law in legal cases. Definition The judiciary is the system of courts that interprets, defends, and applies the law in the name of the state. The judiciary can also be thought of as the mechanism for the resolution of disputes. Under the doctrine of the separation of powers, the judiciary generally does not make statutory law (which is the responsibility of the legislature) or enforce law (which is the responsibility of the executive), but rather interprets, defends, and applies the law to the facts of each case. However, in some countries the judiciary does make common law. In many jurisdictions the judicial branch has the power to change laws through the process of judicial review. Courts with judicial review power may annul the laws and r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Bank
A central bank, reserve bank, or monetary authority is an institution that manages the currency and monetary policy of a country or monetary union, and oversees their commercial banking system. In contrast to a commercial bank, a central bank possesses a monopoly on increasing the monetary base. Most central banks also have supervisory and regulatory powers to ensure the stability of member institutions, to prevent bank runs, and to discourage reckless or fraudulent behavior by member banks. Central banks in most developed nations are institutionally independent from political interference. Still, limited control by the executive and legislative bodies exists. Activities of central banks Functions of a central bank usually include: * Monetary policy: by setting the official interest rate and controlling the money supply; *Financial stability: acting as a government's banker and as the bankers' bank ("lender of last resort"); * Reserve management: managing a country's ...

Direct Democracy
Direct democracy or pure democracy is a form of democracy in which the Election#Electorate, electorate decides on policy initiatives without legislator, elected representatives as proxies. This differs from the majority of currently established democracies, which are representative democracy, representative democracies. The theory and practice of direct democracy and participation as its common characteristic was the core of work of many theorists, philosophers, politicians, and social critics, among whom the most important are Jean Jacques Rousseau, John Stuart Mill, and G. D. H. Cole, G.D.H. Cole. Overview In direct democracy, the people decide on policies without any intermediary or representative, whereas in a representative democracy people vote for representatives who then enact policy initiatives. Depending on the particular system in use, direct democracy might entail passing executive decisions, the use of sortition, making laws, directly electing or dismissing offici ...

Relapse
In internal medicine, relapse or recidivism is a recurrence of a past (typically medical) condition. For example, multiple sclerosis and malaria often exhibit peaks of activity and sometimes very long periods of dormancy, followed by relapse or recrudescence. In psychiatry, relapse or reinstatement of drug-seeking behavior, is the recurrence of pathological drug use, self harm or other symptoms after a period of recovery. Relapse is often observed in individuals who have developed a drug addiction or a form of drug dependence, as well as those who have a mental disorder. Risk factors Dopamine D2 receptor availability The availability of the dopamine receptor D2 plays a role in self-administration and the reinforcing effects of cocaine and other stimulants. The D2 receptor availability has an inverse relationship to the vulnerability of reinforcing effects of the drug. With the D2 receptors becoming limited, the user becomes more susceptible to the reinforcing effects of coca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
