Culture (redirected from Cultural significance)

culture, in anthropology, the integrated system of socially acquired values, beliefs, and rules of conduct which delimit the range of accepted behaviors in any given society. Cultural differences distinguish societies from one another. Archaeology, a branch of the broader field of anthropology, studies material culture, the remains of extinct human cultures (e.g., pottery, weaponry) in order to decipher something of the way people lived. Such analysis is particularly useful where no written records exist. One of the first anthropological definitions of the term was given by Sir Edward Burnett Tylor in the late 19th cent. By 1952, Alfred Kroeber and Clyde Kluckhohn had cataloged over 100 different definitions of the word.

The Nature of Culture

Culture is based on the uniquely human capacity to classify experiences, encode such classifications symbolically, and teach such abstractions to others. It is usually acquired through enculturation, the process through which an older generation induces and compels a younger generation to reproduce the established lifestyle; consequently, culture is embedded in a person's way of life. Culture is difficult to quantify, because it frequently exists at an unconscious level, or at least tends to be so pervasive that it escapes everyday thought. This is one reason that anthropologists tend to be skeptical of theorists who attempt to study their own culture. Anthropologists employ fieldwork and comparative, or cross-cultural, methods to study various cultures. Ethnographies may be produced from intensive study of another culture, usually involving protracted periods of living among a group. Ethnographic fieldwork generally involves the investigator assuming the role of participant-observer: gathering data by conversing and interacting with people in a natural manner and by observing people's behavior unobstrusively. Ethnologies use specialized monographs in order to draw comparisons among various cultures.

Theories of Culture

Investigations have arisen from belief in many different theories of culture and have often given voice to new theoretical bases for approaching the elusive term. Many early anthropologists conceived of culture as a collection of traits and studied the diffusion, or spread, of these traits from one society to another. Critics of diffusionism, however, pointed out that the theory failed to explain why certain traits spread and others do not. Cultural evolution theory holds that traits have a certain meaning in the context of evolutionary stages, and they look for relationships between material culture and social institutions and beliefs. These theorists classify cultures according to their relative degree of social complexity and employ several economic distinctions (foraging, hunting, farming, and industrial societies) or political distinctions (autonomous villages, chiefdoms, and states). Critics of this theory argue that the use of evolution as an explanatory metaphor is flawed, because it tends to assume a certain direction of development, with an implicit apex at modern, industrial society. Ecological approaches explain the different ways that people live around the world not in terms of their degree of evolution but rather as distinct adaptations to the variety of environments in which they live. They also demonstrate how ecological factors may lead to cultural change, such as the development of technological means to harness the environment. Structural-functionalists posit society as an integration of institutions (such as family and government), defining culture as a system of normative beliefs that reinforces social institutions. Some criticize this view, which suggests that societies are naturally stable (see functionalism). Historical-particularists look upon each culture as a unique result of its own historical processes. Symbolic anthropology looks at how people's mental constructs guide their lives. Structuralists analyze the relationships among cultural constructs of different societies, deriving universal mental patterns and processes from the abstract models of these relationships. They theorize that such patterns exist independent of, and often at odds with, practical behavior. Many theories of culture have been criticized for assuming, intentionally or otherwise, that all people in any one society experience their culture in the same way. Today, many anthropologists view social order as a fragile accomplishment that various members of a society work at explaining, enforcing, exploiting, or resisting. They have turned away from the notion of elusive "laws" of culture that often characterizes cross-cultural analyses to the study of the concrete historical, political, and economic forces that structure the relations among cultures. Important theorists on culture have included Franz Boas, Emile Durkheim, Ruth Benedict, and Clifford Geertz.

culture

Integrated pattern of human knowledge, belief, and behaviour that is both a result of and integral to the human capacity for learning and transmitting knowledge to succeeding generations. Culture thus consists of language, ideas, beliefs, customs, taboos, codes, institutions, tools, techniques, works of art, rituals, ceremonies, and symbols. It has played a crucial role in human evolution, allowing human beings to adapt the environment to their own purposes rather than depend solely on natural selection to achieve adaptive success. Every human society has its own particular culture, or sociocultural system. Variation among cultures is attributable to such factors as differing physical habitats and resources; the range of possibilities inherent in areas such as language, ritual, and social organization; and historical phenomena such as the development of links with other cultures. An individual's attitudes, values, ideals, and beliefs are greatly influenced by the culture (or cultures) in which he or she lives. Culture change takes place as a result of ecological, socioeconomic, political, religious, or other fundamental factors affecting a society. See also culture contact; sociocultural evolution.

Culture

The cultivation of cells in the laboratory. Bacteria and yeasts may be grown suspended in a liquid medium or as colonies on a solid medium; molds grow on moist surfaces; and animal and plant cells (tissue cultures) usually adhere to the glass or plastic beneath a liquid medium. Cultures must provide sources of energy and raw material for biosynthesis, as well as a suitable physical environment.

The materials supplied determine which organisms can grow out from a mixed inoculum. Some bacteria (prototrophic) can produce all their constituents from a single organic carbon source; hence they can grow on a simple medium. Other cells (auxotrophic) lack various biosynthetic pathways and hence require various amino acids, nucleic acid bases, and vitamins. Obligatory or facultative anaerobes grow in the absence of O₂; many cells require elevated CO₂. Cultures isolated from nature are usually mixed; pure cultures are best obtained by subculturing single colonies. Viruses are often grown in cultures of a host cell, and may be isolated as plaques in a continuous lawn of those cells. In diagnostic bacteriology, species are ordinarily identified by their ability to grow on various selective media and by the characteristic appearance of their colonies on test media. See Bacterial growth

Laboratory cultures are often made in small flasks, test tubes, or covered flat dishes (petri dishes). Industrial cultures for antibiotics or other microbial products are usually in fermentors of 10,000 gallons (37,850 liters) or more. The cells may be separated from the culture fluid by centrifugation or filtration.

Specific procedures are employed for isolation, cultivation, and manipulation of microorganisms, including viruses and rickettsia, and for propagation of plant and animal cells and tissues. A relatively minute number of cells, the inoculum, is introduced into a sterilized nutrient environment, the medium. The culture medium in a suitable vessel is protected by cotton plugs or loose-fitting covers with overlapping edges so as to allow diffusion of air, yet prevent access of contaminating organisms from the air or from unsterilized surfaces. The transfer, or inoculation, usually is done with the end of a flamed, then cooled, platinum wire. Sterile swabs may also be used and, in the case of liquid inoculum, sterile pipets.

The aqueous solution of nutrients may be left as a liquid medium or may be solidified by incorporation of a nutritionally inert substance, most commonly agar or silica gel. Special gas requirements may be provided in culture vessels closed to the atmosphere, as for anaerobic organisms. Inoculated vessels are held at a desired constant temperature in an incubator or water bath. Liquid culture media may be mechanically agitated during incubation. Maximal growth, which is visible as a turbidity or as masses of cells, is usually attained within a few days, although some organisms may require weeks to reach this stage. See Chemostat
