Cognized Environment
{{short description, Concept of how the people’s culture understands nature, contrasting with the operational environment Cognized environment is a concept first introduced by the late anthropologist Roy Rappaport (1968), in contrast to what he called the ''operational environment'' (see Rappaport 1979:97-144, 1984:337-352). Rappaport was an ecological anthropologist, like Andrew P. Vayda, and wished to contrast the actual reality and adaptations (the operational environment) within a people's ecological niche – say, the existence of tsetse flies and their role in causing sleeping sickness among humans – with how the people’s culture understands nature (the cognized environment) – say, the belief that witches live in those areas that science knows is the habitat of the tsetse. Rappaport’s principal concern was the role of ritual in mediating the cognized and operational environments. Another group of anthropologists later took up the use of Rappaport’s concepts and ...

Anthropologist
An anthropologist is a person engaged in the practice of anthropology. Anthropology is the study of aspects of humans within past and present societies. Social anthropology, cultural anthropology and philosophical anthropology study the norms and values of societies. Linguistic anthropology studies how language affects social life, while economic anthropology studies human economic behavior. Biological (physical), forensic and medical anthropology study the biological development of humans, the application of biological anthropology in a legal setting and the study of diseases and their impacts on humans over time, respectively. Education Anthropologists usually cover a breadth of topics within anthropology in their undergraduate education and then proceed to specialize in topics of their own choice at the graduate level. In some universities, a qualifying exam serves to test both the breadth and depth of a student's understanding of anthropology; the students who pass are pe ...

Roy Rappaport
Roy A. Rappaport (1926–1997) was an American anthropologist known for his contributions to the anthropological study of ritual and to ecological anthropology. Biography Rappaport received his Ph.D. at Columbia University and held a tenured position at the University of Michigan. One of his publications, ''Pigs for the Ancestors: Ritual in the Ecology of a New Guinea People'' (1968), is an ecological account of ritual among the Tsembaga Maring of New Guinea. This book is often considered the most influential and most cited work in ecological anthropology (see McGee and Warms 2004). In that book, and elaborated elsewhere, Rappaport coined the distinction between a people's cognized environment and their ''operational environment'', that is, between how a people understand the effects of their actions in the world and how an anthropologist interprets the environment through measurement and observation. Work Rappaport's work demonstrates the correlation between a culture and its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecological Anthropologist
Ecological anthropology is a sub-field of anthropology and is defined as the "study of cultural adaptations to environments". The sub-field is also defined as, "the study of relationships between a population of humans and their biophysical environment". The focus of its research concerns "how cultural beliefs and practices helped human populations adapt to their environments, and how people used elements of their culture to maintain their ecosystems". Ecological anthropology developed from the approach of cultural ecology, and it provided a conceptual framework more suitable for scientific inquiry than the cultural ecology approach. Research pursued under this approach aims to study a wide range of human responses to environmental problems. Ecological anthropologist, Conrad Kottak published arguing there is an original older 'functionalist', apolitical style ecological anthropology and, as of the time of writing in 1999, a 'new ecological anthropology' was emerging and being reco ...

Andrew P
Andrew is the English form of a given name common in many countries. In the 1990s, it was among the top ten most popular names given to boys in English-speaking countries. "Andrew" is frequently shortened to "Andy" or "Drew". The word is derived from the el, Ἀνδρέας, ''Andreas'', itself related to grc, ἀνήρ/ἀνδρός ''aner/andros'', "man" (as opposed to "woman"), thus meaning "manly" and, as consequence, "brave", "strong", "courageous", and "warrior". In the King James Bible, the Greek "Ἀνδρέας" is translated as Andrew. Popularity Australia In 2000, the name Andrew was the second most popular name in Australia. In 1999, it was the 19th most common name, while in 1940, it was the 31st most common name. Andrew was the first most popular name given to boys in the Northern Territory in 2003 to 2015 and continuing. In Victoria, Andrew was the first most popular name for a boy in the 1970s. Canada Andrew was the 20th most popular name chosen for male ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecological Niche
In ecology, a niche is the match of a species to a specific environmental condition. Three variants of ecological niche are described by It describes how an organism or population responds to the distribution of resources and competitors (for example, by growing when resources are abundant, and when predators, parasites and pathogens are scarce) and how it in turn alters those same factors (for example, limiting access to resources by other organisms, acting as a food source for predators and a consumer of prey). "The type and number of variables comprising the dimensions of an environmental niche vary from one species to another ndthe relative importance of particular environmental variables for a species may vary according to the geographic and biotic contexts". See also Chapter 2: Concepts of niches, pp. 7 ''ff'' A Grinnellian niche is determined by the habitat in which a species lives and its accompanying behavioral adaptations. An Eltonian niche emphasizes that a spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tsetse Flies
Tsetse ( , or ) (sometimes spelled tzetze; also known as tik-tik flies), are large, biting flies that inhabit much of tropical Africa. Tsetse flies include all the species in the genus ''Glossina'', which are placed in their own family, Glossinidae. The tsetse are obligate parasites, which live by feeding on the blood of vertebrate animals. Tsetse have been extensively studied, because of their role in transmitting disease. They have a prominent economic impact in sub-Saharan Africa, as the biological vectors of trypanosomes, causing human and animal trypanosomiasis. Tsetse are multivoltine and long-lived, typically producing about four broods per year, with up to 31 broods over their lifespans. Tsetse can be distinguished from other large flies by two easily-observed features: Primarily, tsetse fold their wings over their abdomens completely when they are resting (so that one wing rests directly on top of the other); Secondly, tsetse also have a long proboscis, extending d ...

Sleeping Sickness
African trypanosomiasis, also known as African sleeping sickness or simply sleeping sickness, is an insect-borne parasitic infection of humans and other animals. It is caused by the species ''Trypanosoma brucei''. Humans are infected by two types, ''Trypanosoma brucei gambiense'' (TbG) and '' Trypanosoma brucei rhodesiense'' (TbR). TbG causes over 98% of reported cases. Both are usually transmitted by the bite of an infected tsetse fly and are most common in rural areas. Initially, the first stage of the disease is characterized by fevers, headaches, itchiness, and joint pains, beginning one to three weeks after the bite. Weeks to months later, the second stage begins with confusion, poor coordination, numbness, and trouble sleeping. Diagnosis is by finding the parasite in a blood smear or in the fluid of a lymph node. A lumbar puncture is often needed to tell the difference between first- and second-stage disease. If the disease is not treated quickly it can lead to death. P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Witch
Witchcraft traditionally means the use of Magic (supernatural), magic or supernatural powers to harm others. A practitioner is a witch. In Middle Ages, medieval and early modern Europe, where the term originated, accused witches were usually women who were believed to have used Black magic, malevolent magic against their own community, and often to have communed with evil beings. It was thought witchcraft could be thwarted by Apotropaic magic, protective magic or counter-magic, which could be provided by cunning folk or folk healers. Suspected witches were also intimidated, banished, attacked or killed. Often they would be formally prosecuted and punished, if found guilty or simply believed to be guilty. European witch-hunts and witch trials in the early modern period led to tens of thousands of executions. In some regions, many of those accused of witchcraft were folk healers or midwife, midwives. European belief in witchcraft gradually dwindled during and after the Age of Enl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neuroanthropology
Neuroanthropology is the study of the relationship between culture and the brain. Overview Neuroanthropology explores how the brain gives rise to culture, how culture influences brain development, structure and function, and the pathways followed by the co-evolution of brain and culture. Moreover, neuroanthropologists consider how new findings in the brain sciences help us understand the interactive effects of culture and biology on human development and behavior. In one way or another, neuroanthropologists ground their research and explanations in how the human brain develops, how it is structured and how it functions within the genetic and cultural limits of its biology (see Biogenetic structuralism anrelated website. "Neuroanthropology" is a broad term, intended to embrace all dimensions of human neural activity, including emotion, perception, cognition, motor control, skill acquisition, and a range of other issues. Interests include the evolution of the hominid brain, cultu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biogenetic Structuralism
Charles D. Laughlin, Jr. (born 1938) is a neuroanthropologist known primarily for having co-founded a school of neuroanthropological theory called " biogenetic structuralism." Laughlin is an emeritus professor of anthropology and religion at Carleton University in Ottawa, Canada. Biography Following service in the American air force, Laughlin completed his undergraduate work in anthropology with a concentration in philosophy at San Francisco State University. He then did graduate work in anthropology at the University of Oregon, beginning in 1966. His doctoral dissertation was based on fieldwork conducted among a small tribe in northeast Uganda called the So (aka Tepeth, Tepes; see Laughlin and Allgeier 1979). Laughlin's choice of the So was influenced by conversations he had with Colin Turnbull, who had worked with nearby peoples. Laughlin completed his dissertation, ''Economics and Social Organization among the So of Northeastern Uganda'', and received his Ph.D. in 1972 while ...

Neuroendocrine System
Neuroendocrinology is the branch of biology (specifically of physiology) which studies the interaction between the nervous system and the endocrine system; i.e. how the brain regulates the hormonal activity in the body. The nervous and endocrine systems often act together in a process called neuroendocrine integration, to regulate the physiological processes of the human body. Neuroendocrinology arose from the recognition that the brain, especially the hypothalamus, controls secretion of pituitary gland hormones, and has subsequently expanded to investigate numerous interconnections of the endocrine and nervous systems. The endocrine system consists of numerous glands throughout the body that produce and secrete hormones of diverse chemical structure, including peptides, steroids, and neuroamines. Collectively, hormones regulate many physiological processes. The neuroendocrine system is the mechanism by which the hypothalamus maintains homeostasis, regulating reproduction, metab ...

Umwelt
In the semiotic theories of Jakob von Uexküll and Thomas A. Sebeok, ''umwelt'' (plural: umwelten; from the German ''Umwelt'' meaning "environment" or "surroundings") is the "biological foundations that lie at the very epicenter of the study of both communication and signification in the human nd non-humananimal". The term is usually translated as "self-centered world". Uexküll theorised that organisms can have different ''umwelten'', even though they share the same environment. The term ''umwelt'', together with companion terms ''Umgebung'' (an Umwelt as seen by another observer) and ''Innenwelt'' (the mapping of the self to the world of objects), have special relevance for cognitive philosophers, roboticists and cyberneticians because they offer a potential solution to the conundrum of the infinite regress of the Cartesian Theater. Discussion Each functional component of an ''umwelt'' has a meaning that represents the organism's model of the world. These functional comp ...
