Physics a set of nuclei formed directly from a preceding set in a chain reaction generation - a body of people who were born in the same period, variously defined.
- the period between the birth of such a group and the birth of their children, which, for demographic purposes, is usually accepted as 30 years.
MANNHEIM distinguished between generation as location (a birth cohort), and generation as actuality, where there is a sense of belonging to a group because of shared experience or feeling, e.g. the Sixties Generation, the Vietnam Generation. See also AGE SET, AGE GROUP, AGEING, LIFE COURSE.Generation in biology, a group of individuals with the same degree of kinship in relation to their common ancestors; the immediate offspring of the preceding generation. The longevity of a generation corresponds to the average reproductive age of an aggregate of individuals in a given species.
Generation in demography, a term referring to people born in the same year. (The term “cohort” is also used.) The interaction and succession of generations constitute the age structure of a society. The term “generation” is also applied to a stage or step in descent from a common ancestor (grandfather, father, son, and so forth), with the interval between steps usually reckoned at 30 years. A society’s age structure and the relationships that develop between generations are biological, social, and historical in character. They are biological in that the alternation of generations is linked to the natural life cycle, and social in that the division of functions among age groups and the criteria for this division depend on the socioeconomic structure of society. They are historical because each generation begins at a particular time. The members of a generation are united by certain lifetime experiences, and therefore, each generation is unique and unrepeatable. In demography, generational analysis makes it possible to discover long-range trends in population dynamics, as well as changes in the patterns of reproduction of the population and the length of productive life, for example. Among the problems studied by sociologists and ethnologists are the relationship between age groups and the social structure, the social division of labor, and the methods of socialization and education of young people. The relationship between age groups and other factors may be rigid and direct or fairly flexible and indirect. In primitive society there was an inflexible, formal system of age groups (sometimes called age classes by ethnologists). Membership in them was formalized and associated with certain specific rights and obligations. In modern society the formal boundaries between age groups have been partially erased and have become indefinite. Nonetheless, age remains an important social and psychological characteristic. In research on cultural history, the concept of the “generation” has primarily a symbolic meaning. It is associated less with a common time of birth than with the common, meaningful experiences of people who participated in or who lived at the time of certain important historical events (for example, “the generation of the October Revolution,” “the generation of the Great Patriotic War”). The concept is also applied to people linked by common intellectual orientations or attitudes (for example, the “lost generation”). The “life span” of such conventional generations is conditional and chronologically loose, and their designations are purely descriptive. The problem of generations is often discussed in connection with the problems of young people and the youth movement. In non-Marxist literature there have been attempts to make the concept of the “generation” the basis for universal historical periodization (for example, in the works of J. Ortega y Gasset and J. Marias of Spain) or to represent the “conflict of generations” as a universal moving force in history (L. S. Feuer of the USA, for example). Marxist sociology rejects so abstract an approach. The age structure of any society is closely linked with its socioeconomic class structure. Therefore, the actual relationships among the representatives of different generations, including the relationships between parents and children, may be understood only in the context of the more general social situation (the pace of historical development, the character of social conflicts, and the level of ideological cohesiveness or division in a society, for example).

Patient discussion about generationQ. Can cancer skip every other generation in your family? Can cancer be so hereditary as to skip every other generation in a family? On my dad's side of the family it seems like it does. Both my great grandmothers on my father's side had cancer (breast cancer and another type) and a great grandfather had cancer as well. My grandparents did not have cancer. My father ended up having cancer out of the three of my grandparents’ children. Me nor any of my cousins have had cancer. Is it possible any of our children will?A. If there is a BRCA mutation, it does not skip generations. A child of a person with a BRCA mutation has a 50/50 chance of having the mutation. Those who have the mutation can pass it on. Those who do not have the mutation cannot pass it on. Q. What alternatives are there for DDD.De generative Disc Disease? I can't sit upright for long periods of time, at times the symptoms are worse and then days and weeks where I feel fine. When I lean into my right legit alleviates it a little but it is excruciating when I shift weight. I also have to sleep with a pillow between my legs and have to shift frequently.I have a lot of strength in my legs and back. But if I stuck in my stomach more and curve my like doing a crunch. the pain is fine.A. Degenerative disc disease can often be successfully treated without surgery. One or a combination of treatments such as Physical therapy, chiropractic manipulative therapy (CMT), osteopathic manipulation, anti-inflammatory medications such as nonsteroidal anti-inflammatory drugs, chiropractic treatments, Traction (orthopedics), or spinal injections often provide adequate relief of these troubling symptoms.
The option of surgery may be recommended if the conservative treatment options do not provide relief within 2 to 3 months. If leg or back pain limits normal activity, if there is weakness or numbness in the legs, if it is difficult to walk or stand, or if medication or physical therapy are ineffective, surgery may be necessary. You should dicucss this with an orthopedic surgeon. Q. Hi I have pain in my knee since 3 years that I thought was generated by weight excess I've lost 28kg but the pain is still here, went to the doctor and he diagnosed a meniscus degenerated (direct translation from spanish, could be incorrect). He told me that there is nothing to do about that and that surgery won't help. My problem is that I love running and I can not do it anymore, everytime I try I start having pain in the back side of my knee and it last for days.I'd love to hear about alternativesRobertoA. Toberro, go to a GOOD health food store and get "Comfrey ointment". Rub this on your knee 2-3 times a day and see how you feel after a month of doing this. I have cured myself of carpal tunnel to avoid surgery doing this and it has also helped me with lower back pain! If you really want to feel better, stop eating any milk or cheese products and sugar! That all contributes to inflammation which arthritis is all about! Be well! :) More discussions about generationAcronymsSeeGENgeneration
