Theory Of Intervening Opportunities
Theory of intervening opportunities attempts to describe the likelihood of migration. Its hypothesis is that this likelihood is influenced most by the opportunities to settle at the destination, less by distance or population pressure at the starting point. Stouffer's law of intervening opportunities states, ''"The number of persons going a given distance is directly proportional to the number of opportunities at that distance and inversely proportional to the number of intervening opportunities."'' Stouffer, ''American Sociological Review'', December 1940, p.846 Stouffer theorises that the amount of migration Migration, migratory, or migrate may refer to: Human migration * Human migration, physical movement by humans from one region to another ** International migration, when peoples cross state boundaries and stay in the host state for some minimum l ... over a given distance is directly proportional to the number of opportunities at the place of destination, and inversely pr ...

Population Pressure
Population pressure, a term summarizing the stress brought about by an excessive population density and its consequences, is used both in conjunction with human overpopulation and with other animal populations that suffer from too many individuals per area (or volume in the case of aquatic organisms). In the case of humans, absolute numbers of individuals may lead to population pressure, but the same is true for overexploitation and overconsumption of available resources and ensuing environmental degradation by otherwise-normal population densities. Similarly, when the carrying capacity of the environment goes down, unchanged population numbers may prove too high and again produce significant pressure. "Pressure" is to be understood metaphorically and hints at the analogy between a gas or fluid that under pressure will tend to escape a bounded container. Similarly, "population pressure" in animal populations in general usually leads to migration activity, and in humans, it may add ...

Samuel A
Samuel ''Šəmūʾēl'', Tiberian: ''Šămūʾēl''; ar, شموئيل or صموئيل '; el, Σαμουήλ ''Samouḗl''; la, Samūēl is a figure who, in the narratives of the Hebrew Bible, plays a key role in the transition from the biblical judges to the United Kingdom of Israel under Saul, and again in the monarchy's transition from Saul to David. He is venerated as a prophet in Judaism, Christianity, and Islam. In addition to his role in the Hebrew scriptures, Samuel is mentioned in Jewish rabbinical literature, in the Christian New Testament, and in the second chapter of the Quran (although Islamic texts do not mention him by name). He is also treated in the fifth through seventh books of ''Antiquities of the Jews'', written by the Jewish scholar Josephus in the first century. He is first called "the Seer" in 1 Samuel 9:9. Biblical account Family Samuel's mother was Hannah and his father was Elkanah. Elkanah lived at Ramathaim in the district of Zuph. His genealog ...

Human Migration
Human migration is the movement of people from one place to another with intentions of settling, permanently or temporarily, at a new location (geographic region). The movement often occurs over long distances and from one country to another (external migration), but internal migration (within a single country) is also possible; indeed, this is the dominant form of human migration globally. Migration is often associated with better human capital at both individual and household level, and with better access to migration networks, facilitating a possible second move. It has a high potential to improve human development, and some studies confirm that migration is the most direct route out of poverty.Age is also important for both work and non-work migration. People may migrate as individuals, in family units or in large groups. There are four major forms of migration: invasion, conquest, colonization and emigration/ immigration. Persons moving from their home due to forced di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Sociological Review
The ''American Sociological Review'' is a bi-monthly peer-reviewed academic journal covering all aspects of sociology. It is published by SAGE Publications on behalf of the American Sociological Association. It was established in 1936. The editors-in-chief are Arthur S. Alderson ( Indiana University-Bloomington) and Dina G. Okamoto (Indiana University-Bloomington). History For its first thirty years, the American Sociological Society (now the American Sociological Association) was largely dominated by the sociology department of the University of Chicago, and the quasi-official journal of the association was Chicago's ''American Journal of Sociology''. In 1935, the executive committee of the American Sociological Society voted 5 to 4 against disestablishing the ''American Journal of Sociology'' as the official journal of society, but the measure was passed on for consideration of the general membership, which voted 2 to 1 to establish a new journal independent of Chicago: the ''Amer ...
