Three-component theory of stratificationThe three-component theory of stratification, more widely known as Weberian stratification or the three class system, was developed by German sociologist Max Weber with class, status and party as distinct ideal types. Weber developed a multidimensional approach to social stratification that reflects the interplay among wealth, prestige and power. Weber argued that power can take a variety of forms. A person's power can be shown in the social order through their status, in the economic order through their class, and in the political order through their party.
Underwater environmentAn underwater environment is a environment of, and immersed in, liquid water in a natural or artificial feature (called a body of water), such as an ocean, sea, lake, pond, reservoir, river, canal, or aquifer. Some characteristics of the underwater environment are universal, but many depend on the local situation. Liquid water has been present on Earth for most of the history of the planet. The underwater environment is thought to be the place of the origin of life on Earth, and it remains the ecological region most critical to the support of life and the natural habitat of the majority of living organisms.
Life chancesLife chances (Lebenschancen in German) is a theory in sociology which refers to the opportunities each individual has to improve their quality of life. The concept was introduced by German sociologist Max Weber in the 1920s. It is a probabilistic concept, describing how likely it is, given certain factors, that an individual's life will turn out a certain way. According to this theory, life chances are positively correlated with one's socioeconomic status.
