UnemploymentUnemployment, according to the OECD (Organisation for Economic Co-operation and Development), is people above a specified age (usually 15) not being in paid employment or self-employment but currently available for work during the reference period. Unemployment is measured by the unemployment rate, which is the number of people who are unemployed as a percentage of the labour force (the total number of people employed added to those unemployed).
CrimeIn ordinary language, a crime is an unlawful act punishable by a state or other authority. The term crime does not, in modern criminal law, have any simple and universally accepted definition, though statutory definitions have been provided for certain purposes. The most popular view is that crime is a created by law; in other words, something is a crime if declared as such by the relevant and applicable law. One proposed definition is that a crime or offence (or criminal offence) is an act harmful not only to some individual but also to a community, society, or the state ("a public wrong").
Natural rate of unemploymentThe natural rate of unemployment is the name that was given to a key concept in the study of economic activity. Milton Friedman and Edmund Phelps, tackling this 'human' problem in the 1960s, both received the Nobel Memorial Prize in Economic Sciences for their work, and the development of the concept is cited as a main motivation behind the prize. A simplistic summary of the concept is: 'The natural rate of unemployment, when an economy is in a steady state of "full employment", is the proportion of the workforce who are unemployed'.
Hate crimeA hate crime (also known as a bias-motivated crime or bias crime) is a prejudice-motivated crime which occurs when a perpetrator targets a victim because of their membership (or perceived membership) of a certain social group or racial demographic. Examples of such groups can include, and are almost exclusively limited to ethnicity, disability, language, nationality, physical appearance, political views and/or affiliation, age, religion, sex, gender identity, or sexual orientation.
Crimes against humanityCrimes against humanity are widespread or systemic criminal acts which are committed by or on behalf of a de facto authority, usually by or on behalf of a state, that grossly violate human rights. Unlike war crimes, crimes against humanity do not have to take place within the context of wars, and they apply to widespread practices rather than acts which are committed by individuals. Although crimes against humanity apply to acts which are committed by or on behalf of authorities, they do not need to be part of an official policy, and they only need to be tolerated by authorities.
Crime statisticsCrime statistics refer to systematic, quantitative results about crime, as opposed to crime news or anecdotes. Notably, crime statistics can be the result of two rather different processes: scientific research, such as criminological studies, victimisation surveys; official figures, such as published by the police, prosecution, courts, and prisons. However, in their research, criminologists often draw on official figures as well. There are several methods for the measuring of crime.
Exploratory data analysisIn statistics, exploratory data analysis (EDA) is an approach of analyzing data sets to summarize their main characteristics, often using statistical graphics and other data visualization methods. A statistical model can be used or not, but primarily EDA is for seeing what the data can tell us beyond the formal modeling and thereby contrasts traditional hypothesis testing. Exploratory data analysis has been promoted by John Tukey since 1970 to encourage statisticians to explore the data, and possibly formulate hypotheses that could lead to new data collection and experiments.
Youth unemploymentYouth unemployment is the situation of young people who are looking for a job but cannot find a job, with the age range being defined by the United Nations as 15–24 years old. An unemployed person is defined as someone who does not have a job but is actively seeking one. To be qualified as unemployed for official and statistical measurement, the individual must be without employment, willing and able to work, of the officially designated "working age" (often from the teens to the mid-60s) and actively searching for a position.
Dependent and independent variablesDependent and independent variables are variables in mathematical modeling, statistical modeling and experimental sciences. Dependent variables are studied under the supposition or demand that they depend, by some law or rule (e.g., by a mathematical function), on the values of other variables. Independent variables, in turn, are not seen as depending on any other variable in the scope of the experiment in question. In this sense, some common independent variables are time, space, density, mass, fluid flow rate, and previous values of some observed value of interest (e.
Japanese war crimesThe Empire of Japan committed war crimes and crimes against humanity in many Asian-Pacific countries during the period of Japanese imperialism, primarily during the Second Sino-Japanese and Pacific Wars. These incidents have been described as "the Asian Holocaust". Some war crimes were committed by Japanese military personnel during the late 19th century, but most were committed during the first part of the Shōwa era, the name given to the reign of Emperor Hirohito.
